[0005] To achieve the above object, the utility model provides the following technical scheme: a track locomotive backstop fixing structure, including the protection shell, the front end surface fixed mounting of protection shell has rear baffle, the protection shell in fixed mounting has the connecting plate, the protection shell in rotation mounting has the connecting rod, both sides end surfaces of connecting rod all fixed mounting has the knob, the connecting rod fixed mounting has two first gear plates, two first gear plates are opposite arrangement, the connecting plate in rotation mounting has two second gear plates that are opposite arrangement, the bottom of two second gear plates all penetrates to connecting plate, second gear plate and first gear plate are intermeshed, the bottom of protection shell is equipped with the limiting groove.
[0006] By rotating the knob installed on one side of the connecting rod to make the connecting rod rotate, and because there are two first gear plates installed on the connecting rod, and the second gear plates are rotatably installed on the connecting plate and intermeshed with the first gear plates, when the connecting rod drives the first gear plates to rotate, the second gear plates will also rotate, because the sleeve is installed on the bottom of the second gear plate, and the threaded block is arranged in the sleeve and intermeshed with the threaded groove in the sleeve, so when the second gear plate rotates, the sleeve can be better rotated.
[0007] Preferably, the bottom of the second gear plate is fixedly provided with a sleeve, the sleeve is provided with a threaded groove, the bottom of the sleeve is fixedly provided with a limiting plate, and the limiting plate is provided with a through hole.
[0008] The sleeve is installed at the bottom of the second gear plate, the threaded block is arranged in the sleeve, and the threaded block is engaged with the threaded groove in the sleeve, so that when the second gear plate rotates, the sleeve can rotate, so that the threaded block engaged in the sleeve drives the fixed rod to move, and the limiting plate arranged at the bottom of the sleeve can better limit the threaded block.
[0009] Preferably, the sleeve is provided with a threaded block, the threaded block and the threaded groove in the sleeve are engaged with each other, the bottom of the threaded block is fixedly provided with a fixed rod, the fixed rod penetrates the through hole, and the bottom of the fixed rod is fixedly provided with a fixed block arranged in the limiting groove.
[0010] The fixed block at the bottom of the fixed rod is inserted into the limiting groove, so that when the sleeve rotates, the threaded block can better move up and down in the sleeve, and after the threaded block drives the fixed block to extend out of the limiting groove, the worker inserts the fixed block into the recess pre-formed on the outside, so as to fix it.
[0011] Preferably, the top end of the protective shell is provided with a slot, the rear end surface of the protective shell is provided with two positioning grooves, the top end of the protective shell is provided with a top plate, both side end faces of the top plate are fixedly provided with an insertion block, the rear end surface of the top plate is fixedly provided with two positioning plates, the positioning plates and the positioning grooves are both provided with positioning holes, and the positioning holes are inserted with positioning bolts.
[0012] The positioning bolt is removed, so that the limitation between the top plate and the protective shell is cancelled, and then after the limitation between the top plate and the protective shell is cancelled, the worker pulls out the top plate outward, so that the insertion blocks at both ends of the top plate are pulled out of the slots formed in the protective shell, so that the top plate is taken out of the protective shell. In this way, the worker can better lubricate and maintain the first gear plate and the second gear plate.
[0013] Preferably, the connecting rod, the fixed rod and the fixed block are made of cast iron.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The rear stop fixing structure of this railcar uses a knob installed on one side of the connecting rod to rotate the connecting rod. Since there are two first gear plates installed on the connecting rod, when the connecting rod drives the first gear plate to rotate, the second gear plate will also rotate. When the second gear plate rotates, it can effectively rotate the sleeve, thereby causing the threaded block inside the sleeve to move the fixing rod. After the threaded block drives the fixing block to extend out of the limiting groove, the fixing block is inserted into the pre-opened groove on the outside, which can be adjusted effectively. This makes the rear stop more stable after fixing and also simple to operate.
[0017] 2. The rear stop fixing structure of this railcar allows the restriction between the top plate and the protective shell to be removed by removing the positioning bolts. After the restriction between the top plate and the protective shell is removed, the workers can pull the top plate outward to remove the inserts installed at both ends of the top plate from the slots opened in the protective shell, thus removing the top plate from the protective shell. This facilitates the workers to apply lubricating oil to the first gear plate and the second gear plate and also allows for better maintenance. Attached Figure Description
