Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
Examples
The belt replacing device of the belt conveyor, as shown in fig. 1 to 6, comprises a supporting seat 1, a guide frame 2 and a traction mechanism. The supporting seat 1 comprises a base 11 and two vertical supporting plates 12 fixedly arranged on the base 11. The guide frame 2 is used for guiding the cut old belt 5 to move from the gap at the upper part of the tension pulley 6 of the belt conveyor to the outside of the belt conveyor, one end of the guide frame 2 is connected with the two vertical support plates 12 of the support seat 1, and the other end of the guide frame is used for extending into the gap at the upper part of the tension pulley 6 of the belt conveyor. The pulling mechanism is used for pulling the old belt 5 to move along the guide frame 2.
As shown in fig. 2, one end of the guide frame 2 close to the support seat 1 is perpendicular to one end of the guide frame 2 far from the support seat 1. Because the opening of the gap above the tension pulley 6 of the belt conveyor is smaller, and the opening direction is vertical to the moving direction of the conveyor belt, in order to install the device, the two ends of the guide frame 2 of the device are set to be vertical to each other, when the device is used, only the support seat 1 is needed to be placed outside the belt conveyor, one side of the support seat 1, which is provided with the guide frame 2, is just opposite to the tension pulley 6, then one end of the guide frame 2 is inserted into the gap above the tension pulley 6, the guide frame 2 inserted into the gap above the tension pulley 6 can be just opposite to the cutting surface of the old belt 5, the whole device is not needed to be placed into the gap above the tension pulley 6, after the guide frame 2 is sent into the gap above the tension pulley 6, the guide frame 2 can be just opposite to the cutting part of the old belt 5 without a worker repeatedly adjusting the angle of the guide frame 2, the installation is simple and convenient, the efficiency is high, and when the guide frame 2 is just opposite to the cutting surface of the old belt 5 to enable the traction mechanism to pull the old belt 5 to move, the old belt 5 can move along the moving direction of the new belt 4 under the guiding action of the lead frame, and the situation that the position of the new belt 4 is deviated due to the friction force between the old belt 5 and the new belt 4 when the old belt 5 is pulled out of the belt conveyor can not occur.
As shown in fig. 2, a contact roller 21 is rotatably disposed at an end of the guide frame 2 away from the support base 1, and the contact roller 21 is used for pressing against a position where the new belt 4 is located at the cut-off position of the old belt 5.

The working process is as follows:
when the device is used for pulling out an old belt 5 of a belt conveyor, one side of the device, which is provided with the guide frame 2, faces a tension pulley 6 of the belt conveyor, then the support seat 1 is moved to send one end of the guide frame 2, which is far away from the support seat 1, into a gap above the tension pulley 6, the contact roller 21 on the guide frame 2 is pressed against a new belt 4 at the cut-off part of the old belt 5, the contact roller 21 can rotate synchronously with the new belt 4, at the moment, one end of the guide frame 2, which is far away from the support seat 1, is opposite to the cut-off surface of the old belt 5, and then the chuck 31 is pulled out from the first material receiving roller assembly 32, so that the traction lines of the two chucks 31 and the connecting chuck 31 move to one end of the guide frame 2, which is far away from the support seat 1, along the direction of the guide frame 2. The pressing handle 313 of the moving chuck 31 makes the eccentric roller 314 on the pressing handle 313 press against the movable clamping block 312 to move towards the direction close to the clamping part 3111, so that the two chucks 31 are respectively clamped on the cut ends of the old belt 5 in parallel, then the rocker arm 351 is rotated, the rocker arm 351 drives the driving gear 352 to rotate, the driving gear 352 further drives the driven gear 353 to rotate, the reel 321 fixedly connected with the driven gear 353 rotates, the reel 321 rotates to pull the traction rope 34 on the reel 321, the traction rope 34 is tensioned and is rewound and taken back on the reel 321 along with the rotation of the reel 321, so that the chucks 31 and the old belt 5 clamped by the chucks 31 move along the guide frame 2 towards the direction close to the supporting seat 1 along with the traction rope 34, when the rocker arm 351 is rotated, the conveyor can be intermittently clicked, the old belt 5 and the new belt 4 rotate, the labor of workers for rotating the rocker arm 351 can be saved, it is also possible to reduce the friction between the old belt 5 and the new belt 4 and protect the new belt 4. With the rotation of the rocker arm 351, when the old belt 5 is pulled to be close to the first material receiving roller assembly 32 and the second material receiving roller assembly 33, the pressure rod 362 is pressed downwards, the contact cylinder 365 on the pressure rod 362 abuts against the first link 363, so that the end of the first link 363 hinged with the second link 364 moves downwards, the second link 364 further moves downwards, the second link 364 pushes the sliding block 331 to move downwards against the tension of the return spring 361 when moving downwards, so that the sliding block 331 drives the rotating shaft 332 to move downwards, the distance between the second material receiving roller assembly 33 and the first material receiving roller assembly 32 is increased, the rocker arm 351 is continuously rotated, so that the collet 31 drives the old belt 5 to pass through the gap between the first material receiving roller assembly 32 and the second material receiving roller assembly 33, then the pressure knob 313 is reversely moved, so that the eccentric roller 314 on the pressure knob 313 does not abut against the movable clamping block 312 any more, and the collet 31 loosens the clamping of the old belt 5, the collet 31 is separated from the old belt 5 and then the collet 31 is caught at the gap between the main winding roller 322 and the sub-winding roller 323. The downward pressure on the pressure rod 362 is released, so that the second material receiving roller assembly 33 moves upwards under the action of the elastic restoring force of the return spring 361, the second material receiving roller assembly 33 and the first material receiving roller assembly 32 are respectively abutted to two side faces of the old belt 5, the rocker arm 351 is continuously rotated, the first material receiving roller assembly 32 rotates, the old belt 5 is continuously pulled to move towards the outside of the conveyor along the guide frame 2 under the coordination of the second material receiving roller, and the old belt 5 is pulled out of the conveyor completely, so that the pulling-out work of the old belt 5 of the conveyor is completed.
