[0020] like Figure 1-6 As shown, an electric-driven sled with an anti-collision device comprises a sled 1, a connecting piece 2 for connecting with a rail trolley is connected to the front side of the sled 1, a mounting frame 3 is connected below the connecting piece 2, a front anti-collision device is installed on the front side of the mounting frame 3, the front anti-collision device comprises a first shock-absorbing alarm component 4 and a second shock-absorbing alarm component 5, the front ends of the first shock-absorbing alarm component 4 and the second shock-absorbing alarm component 5 are connected with a first shock-absorbing plate 6, a sliding rod 8 is connected between the first shock-absorbing alarm component 4 and the second shock-absorbing alarm component 5, a first sliding seat 9 and a second sliding seat 12 are sleeved on the sliding rod 8, and the first sliding seat 9 and the second sliding seat 12 are sleeved on the sliding rod 8. A first compression spring 10 is connected between the first shock-absorbing alarm component 4, a second compression spring 13 is connected between the second slide 12 and the second shock-absorbing alarm component 5, a first connecting rod 11 is hinged between the first slide 9 and the first shock-absorbing plate 6, and a second connecting rod 14 is hinged between the second slide 12 and the first shock-absorbing plate 6; a rear anti-collision device is installed on the rear side of the sliding vehicle 1, and the rear anti-collision device includes a third shock-absorbing alarm component 15, and a second shock-absorbing plate 16 is connected to the rear end of the third shock-absorbing alarm component 15, and a plurality of rubber blocks 7 are bonded to the first shock-absorbing plate 6 and the second shock-absorbing plate 16, and the rubber blocks 7 play a certain buffering role.

[0021] like Figure 4As shown, the mounting frame 3 includes a main body 301, which is arranged in an inverted U shape, and the main body 301 is welded or bolted to the bottom surface of the connecting member 2, and two fixing plates 302 are welded or bolted to the lower part of the main body 301, and the first shock absorbing alarm component 4 and the second shock absorbing alarm component 5 are respectively installed on the left and right fixing plates 302.

[0022] The first shock absorbing alarm component 4, the second shock absorbing alarm component 5 and the third shock absorbing alarm component 15 have the same structure. The first shock absorbing alarm component 4 is taken as an example to introduce its specific structure, and the structures of the second shock absorbing alarm component 5 and the third shock absorbing alarm component 15 are not repeated here. Figure 5 As shown, the first shock-absorbing alarm component 4 includes a fixed cylinder 401, a cylindrical piston chamber 402 is opened inside the fixed cylinder 401, the internal sliding seal of the cylindrical piston chamber 402 is matched with a piston 403, a third compression spring 404 is connected between the piston 403 and the inner wall of the cylindrical piston chamber 402, and a movable rod 406 is connected to the end of the piston 403 away from the third compression spring 404, and the movable rod 406 extends to the outside of the fixed cylinder 401, a whistle 405 is installed on the top of the fixed cylinder 401, and the whistle 405 is communicated with the cylindrical piston chamber 402, and a gas one-way valve 407 is installed at the bottom of the fixed cylinder 401, and the gas one-way valve 407 is communicated with the cylindrical piston chamber 402.

[0023] When the first shock-absorbing plate 6 collides with the walking frame, the first shock-absorbing plate 6 squeezes the movable rod 406, and the movable rod 406 pushes the piston 403 to move in the direction of the third compression spring 404. The piston 403 pushes the third compression spring 404 to compress, which plays a buffering role. When the space of the third compression spring 404 is compressed, it exhausts air to the outside through the whistle 405, and blows the whistle 405 while exhausting air. After the whistle 405 is blown, it can remind the operator that the sliding trolley is about to hit the wall and needs to be dealt with in time; in addition, a gas one-way valve 407 that communicates with the outside atmosphere is connected at the bottom of the third compression spring 404. When the piston 403 is reset, the gas one-way valve 407 is turned on, and the outside air enters the cylindrical piston chamber 402, making the piston 403 reset more smoothly; the action process of the second shock-absorbing alarm component 5 is the same as that of the first shock-absorbing alarm component 4, which will not be repeated here.

[0024] When the first shock-absorbing plate 6 moves rearward after being hit, the first connecting rod 11 drives the first slide seat 9 to move along the slide rod 8, squeezing the first compression spring 10, and the second connecting rod 14 drives the second slide seat 12 to move along the slide rod 8, squeezing the second compression spring 13, thereby playing a shock-absorbing and buffering role, reducing damage to the sliding vehicle and improving safety.

[0025] In actual operation, when the sliding trolley moves backward, the operator will be more careful and pay more attention, and the probability of collision is relatively small, so only the third shock-absorbing alarm component is designed in the rear anti-collision device; when the sliding trolley moves to the rear side, the second shock-absorbing plate 16 in the rear anti-collision device collides with the walking frame, and the whistle in the third shock-absorbing alarm component 15 blows to remind the operator, and the piston in the third shock-absorbing alarm component 15 squeezes the compression spring, which also plays a buffering role.

[0026] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
