Background
The hydraulic strain clamp is used as an important connecting hardware fitting of the power transmission line, and the safe operation of the hydraulic strain clamp has important significance on the safety of a power grid. The hydraulic strain clamp is used for fixing a longer extending lead to bear the extending tension of the lead in the length direction and hanging the lead to a strain insulator-string group or a hardware fitting on a tower, and the strain clamp is generally used for corner and connection in lead laying and terminal connection; the hydraulic tension-resistant wire clamp not only plays a role in bearing the tension of a line, but also plays a role in transmitting load current. When the hydraulic strain clamp is actually used on site, the hydraulic strain clamp is usually used in pairs.
For the transmission line, when the operating temperature of the hydraulic strain clamp exceeds the maximum bearing temperature, the clamp is overheated, and the transmission quality of electric energy is directly influenced. The light strain clamp generates heat to cause electric energy loss, the heavy strain clamp breaks to cause large-area power failure accidents, and the heating condition of the strain clamp in operation is related to the load flow, the contact condition of the drainage plate, the material and the like; the abnormal heating of the wire clamp is mainly contact looseness, so that the heating caused by overlarge contact resistance is caused. The bolt plays a key role in the tightness of the electrical contact of the wire clamp, and the magnitude of the contact pressure is closely related to the tightness of the bolt.
The hydraulic tension clamp commonly used at present generally comprises a pipe body, a steel anchor is inserted into one end of the pipe body, and a drainage clamp extending outwards is fixedly connected onto the pipe body through a bolt. When traditional hydraulic pressure strain clamp used, need with spiral aluminium package copper wire cartridge to the body, with the fixed crimping of hydraulic pressure mode with body, steel anchor, spiral aluminium package copper wire together, just so connect into close inseparable body structure with the three. Traditional hydraulic pressure strain clamp simple structure, it is also very convenient to operate, and is very extensive in electric power system application, and its weak point lies in: the drainage wire clamp is only pressed on the tube body through the bolt and is electrically connected with the tube body by virtue of pressing force, so that the problem that the poor electrical connection between the drainage wire clamp and the tube body is caused due to the fact that the bolt is loosened after long-term use exists.
When the wire clamp loosens or is poorly connected, the wire clamp can be caused to generate heat, and the transmission quality of electric energy is directly influenced. The light strain clamp generates heat to cause electric energy loss, the heavy strain clamp is blown to cause large-area power failure accidents, and the heating condition of the strain clamp in operation is related to load current, the contact condition of the drainage plate, the material and the like; the abnormal heating of the wire clamp is mainly the loosening of a connecting point, so that the heating caused by the overlarge contact resistance is caused. The bolt plays a key role in the tightness degree of the contact of the clamping points, and the magnitude of the contact pressure is closely related to the tightness degree of the bolt.

Specifically, the long axis 201b is a circular axis, the contact piece 203 is also a circular axis, and the through hole 201c is a circular hole.
The ring groove 201b-1 provides a space for the stopper 201d-1 to be placed, in an initial state, the stopper 201d-1 is located in the ring groove 201b-1, the third spring 201b-4 is connected to the inner side of the stopper 201d-1, so that the stopper 201d-1 is kept in the ring groove 201b-1, the second guide groove 201b-2 is matched with the trigger 201d, and meanwhile, the matching limits the trigger 201d to enable the trigger 201d to move only along the radial direction of the long shaft 201 b.
The structure of the unassembled locking member 202 is shown in fig. 7, in which the blocking piece 202c is located at the end of the first spring 202d, the first spring 202d occupies most of the space in the receiving groove 202a, at this time, the blocking piece 201s-1 cannot enter the receiving groove 202a, a portion of the end of the push rod 202j extends to the outside of the locking member 202, the rotating member 202k can rotate around the rotating shaft 202k-1 under the connection between the rotating shaft 202k-1 and the fixing groove 202i, in the initial state, the blocking piece 202c contacts with one end of the rotating member 202k, and the second spring 202h is in the natural state.
After the locking member 202 is sleeved on the long shaft 201b, the push rod 202j contacts with the side surface of the first wire clamp 101, the locking member 202 continues to approach the first wire clamp 101, the push rod 202j is pushed towards the inside of the locking member 202, specifically, the second spring 202h is stretched, one end of the rotating member 202k is pushed, so that the rotating member 202k starts to rotate, the other end of the rotating member 202k shifts the blocking piece 202c to move towards one side of the first spring 202d, so that the first spring 202d is compressed, and the space between the blocking piece 202c and one side of the accommodating groove 202a is vacated, which is in the state shown in fig. 5.
The positioning bar 201c-1 and the second guiding groove 201b-2 are matched to position the abutting piece 203, after the locking piece 202 is installed, the abutting piece 203 is inserted into the through hole 201c, the end of the abutting piece 203 is contacted with the positioning bar 201c-1 after the abutting piece 203 is inserted, at the moment, the abutting piece 203 is rotated, the positioning groove 203a is enabled to correspond to the positioning bar 201c-1, and the abutting piece 203 can be continuously inserted into the through hole 201c inwards.
It should be noted that the height of the positioning bar 201c-1 is smaller than the groove depth of the positioning groove 203a where the high surface 203a-1 is located, and at this time, the positioning bar 201c-1 does not touch the transition surface 203a-2, so as to prevent the abutting member 203 from being blocked and unable to move forward.
Since the positioning bar 201c-1 and the second guiding groove 201b-2 are located on the same radial plane, that is, the positioning groove 203a corresponds to the position of the trigger 201d, the touch member 203 continues to enter, and the trigger 201d enters the positioning groove 203a, when the stop block 201d-1 is in the annular groove 201b-1, the bottom of the touch block 201d is at a position corresponding to the transition surface 203a-2, specifically, a position close to the lower surface 203a-3, and at this time, the touch block 201d is continuously pushed into the touch piece 203, the bottom of the touch block 201d contacts the transition surface 203a-2, and the contact block 201d is pushed by the transition surface 203a-2 to move radially outward, and then the stopper 201d-1 moves into the receiving groove 202a, one end of the stopper 201d-1 contacts with one side of the blocking piece 202c, and the other end contacts with one side of the accommodating groove 202 a.
It should be noted that, when the push rod 202j is completely located in the locking member 202, the space in the receiving groove 202a left after the blocking piece 202c is shifted can accommodate the stop 201d-1 to enter, and is in interference fit, so that the outer edge of the stop 201d-1 located at one end of the blocking piece 202c is provided with a chamfer, when the stop 201d-1 enters the receiving groove 202a, the stop 201d-1 further pushes the blocking piece 202c, so that the first spring 202d is further compressed, and the pushing force of the first spring 202d on the blocking piece 202c is applied to the stop 202 d-1.
In this state, the force applied by the blocking piece 202c to the rotating piece 202k is reduced, and meanwhile, in this state, the stop 201d-1 is located in the accommodating groove 202a, and the touch block 201d connected to the stop 201d-1 is located in the positioning groove 203a and the second guide groove 201b-2, that is, the whole of the stop 201d-1 and the touch block 201d is connected to the inserting piece 201, the locking piece 202 and the abutting piece 203, and the three are fixed together.
The first spring 202d applies a force to the stopper 201d-1 through the stopper 202c to clamp the stopper 201d-1, so that the locking member 202 is fixed between the stopper 201d-1 and the first wire clamp 101.
