Abstract

The present invention relates to a long-distance gripping device for fuel balls of ball bed high-temperature air cooled reactors, which belongs to the technical field of reactor engineering. In the device, a pull plate is arranged in a handle and is linked with a pull rod through a pull rod shaft, a steel cable and a connecting rod in sequence, and a gripping claw is linked with the pull rod through male pins. A connecting pipe is fixed on the handle and is sheathed outside the steel cable, a first bushing is sheathed outside the steel cable, and one end of the first bushing is inserted into the connecting pipe. A second bushing is sheathed outside the connecting rod, one end of the second bushing is inserted into the first bushing, and the connecting position of the first and the second bushings is fixed relatively by a fixing support frame and round nuts. A spring is sheathed outside the steel cable and is arranged in the first bushing. The gripping device of the present invention can grip radioactive fuel balls from a long distance and reduces the radiation dose to operators. Fuel balls are gripped firmly and can not drop off in the transferring process, the fuel balls are released once, and the operation is free. The movement of the gripping claw is flexible, and the phenomena that the gripping claw can not open or can not grip a fuel ball can not occur.

Description

Long-range picker of fuel ball of ball bed high-temperature air cooled reactor
Technical field
The present invention relates to a kind of long-range picker of fuel ball of ball bed high-temperature air cooled reactor, belong to the reactor engineering technical field, be used for the remote extracting and the transhipment of pebble bed high temperature reactor radioactive fuel ball.
Background technology
Pebble bed high temperature reactor at some in particular cases, having radioactive fuel sphere is scattering on the ground, or be rolled into a certain position, this radioactive fuel sphere does not allow personnel close, more do not allow to clutch, collect these radioactive fuel balls if handle, must adopt remote machinery picks tools, be subjected to excessive radio exposure to avoid personnel.
Summary of the invention
The objective of the invention is to propose a kind of long-range picker of fuel ball of ball bed high-temperature air cooled reactor, can grasp the radioactive fuel ball at a distance, be subjected to the injury of radio exposure to avoid the staff.
The long-range picker of fuel ball of ball bed high-temperature air cooled reactor that the present invention proposes comprises handle, arm-tie, pull rod shaft, wire rope, adapter, first sleeve pipe, second sleeve pipe, spring, connecting rod, pull bar and grabs lobe.Arm-tie places in the handle, and arm-tie is successively by pull rod shaft, wire rope, connecting rod and pull bar interlock.Grab lobe and be installed in rotation on the parts that link together with second sleeve pipe, an end of grabbing end of lobe and pull bar is hinged, the other end of pull bar and rod hinge connection.Adapter is fixed on the handle, and is enclosed within outside the wire rope.First casing pipe sleeve is outside wire rope, in the one end inserts and takes over; Described second casing pipe sleeve is outside connecting rod, and the one end inserts first sleeve pipe, and the junction of first sleeve pipe and second sleeve pipe is by fixed support and round nut relative fixed.Spring housing and places in first sleeve pipe outside wire rope.When the pulling arm-tie, connecting rod drives pull bar and moves to handle orientations, thereby compression spring unclamps arm-tie, and connecting rod and spring move to the direction of grabbing lobe under the effect of the restoring force of spring, make to grab the lobe closure.
The long-range picker of fuel ball of ball bed high-temperature air cooled reactor that the present invention proposes, it is a long handle specific purpose tool that is used for gripping radioactive fuel ball, be used for to be scattered in the outer fuel sphere gripping of container and be returned in original place or the safety container, also can be used to remove fuel element.Its advantage is: (1) grabbing device is designed to closed type, promptly under conventional state, grabbing device is in the state of clamping ball, when only grasping the arm-tie and the application of force, grabbing device just is in open configuration, therefore can avoid fully in removing the process of ball because the absent minded misoperation of operating personnel is scattered the radioactive fuel ball once more.(2) grasp ball at a distance, significantly reduce the radiation dose that operating personnel are subjected to.The suffered radiation dose of operating personnel size and personnel square are inversely proportional to from the radioactive source distance, the distance of 4m for example, and the suffered dosage of personnel be 1/16 of close radiation source positions.(3) effective length of the remote grabbing device of fuel sphere can also can extend or shorten according to actual needs.The device parts mainly adopt aluminum alloy materials, therefore from heavy and light, and flexible operation, convenience.(4) scope of opening of grabbing lobe in apparatus of the present invention can design according to actual needs, and it is spherical grasping article, therefore also can be used to grasp other approximate spherical article.
Description of drawings
Fig. 1 is the result schematic diagram of the long-range picker of fuel ball of ball bed high-temperature air cooled reactor that proposes of the present invention.
Among Fig. 1, the 1st, handle, the 2nd, arm-tie, the 3rd, pull rod shaft, the 4th, wire rope, the 5th, take over, 6 is first sleeve pipes, the 7th, spring, the 8th, round nut, the 9th, fixed support, the 10th, connecting rod, the 11st, pull bar, the 12nd, grab lobe, 13 is second sleeve pipes, the 14th, pin.
Embodiment
The long-range picker of fuel ball of ball bed high-temperature air cooled reactor that the present invention proposes, its structure comprises handle 1, arm-tie 2, pull rod shaft 3, wire rope 4, takes over 5, first sleeve pipe 6, second sleeve pipe 13, spring 7, connecting rod 10, pull bar 11 and grab lobe 12 as shown in Figure 1.Arm-tie 2 places in the handle 1, and arm-tie 2 is successively by pull rod shaft 3, wire rope 4, connecting rod 10 and pull bar 11 interlocks.Grab lobe 12 and be installed in rotation on the parts that link together with second sleeve pipe 13, an end of grabbing end of lobe 12 and pull bar 11 is hinged, and the other end of pull bar and connecting rod 10 are hinged.Take over 5 and be fixed on the handle 1, and be enclosed within outside the wire rope 4.First sleeve pipe 6 is enclosed within outside the wire rope 4, and the one end inserts to be taken in 5.Second sleeve pipe 13 is enclosed within outside the connecting rod 10, and the one end inserts the junction of first sleeve pipe, 6, the first sleeve pipes 6 and second sleeve pipe 13 by fixed support 9 and round nut 8 relative fixed.Spring 7 is enclosed within outside the wire rope 4, and places in first sleeve pipe 6.When pulling arm-tie 2, connecting rod 10 drives pull bar 11 and moves to handle 1 direction, thereby compression spring 7 unclamps arm-tie 2, and connecting rod 10 and spring 7 move to the direction of grabbing lobe 12 under the effect of the restoring force of spring, make to grab lobe 12 closures.
Below in conjunction with accompanying drawing, introduce the principle of work of grabbing device of the present invention in detail:
During original state, pull bar 11 and grab lobe 12 and be in the position shown in Fig. 1 dotted line, promptly grabbing device is in the position of extracting.When the needs extracting is scattered in the fuel sphere of ground or other position, with pulling moving arm-tie 2, make pull rod shaft 3 move to handle 1 direction together with wire rope 4, connecting rod 10 drives pull bar 11 and also moves to handle 1 direction, thereby compression spring 7 makes spring 7 be in compressive state.Grab lobe 12 and move along with pull bar 11 and open, be in the position shown in the solid line among Fig. 1.When grabbing after lobe 12 catches fuel sphere, unclamp the hand of catching arm-tie 2, connecting rod 10 and pull bar 11 to the direction motion of grabbing lobe 12, make and grab that lobe 12 moves along with pull bar 11 and closed, thereby clamp fuel sphere under the restoring force effect of spring.
The remote grabbing device of fuel sphere of the present invention's design, the folder ball is fastening, can not lose in transfer, and once finish release, and operation is grabbed the lobe motion flexibly, the phenomenon that fuel sphere can not take place to open not open or can't clip freely.
