Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses a cage with a car stopper 200. Referring to fig. 1 and 2, a cage with a car stopper 200 includes a base plate 110 and two rails 120 parallel to each other. The rails 120 are laid on the base plate 110 and fixed to the base plate 110 by bolts. The mine car 400 includes wheels 410 and a hopper 420, the wheels 410 are rotatably connected to the bottom of the hopper 420, and the wheels 410 roll on the rails 120. The bottom plate 110 is also provided with two car stoppers 200 which are symmetrical with each other and used for stopping the mine car 400 from walking, and one car stopper 200 corresponds to one rail 120.

Referring to fig. 1 and 2, each car stopper 200 includes a rotation shaft fixedly installed on the base plate 110, a rotation member rotated on the rotation shaft, and a car stopper 220 for stopping on the rail 120. The bottom surface of the bottom plate 110 is fixedly connected or welded with two opposite channel steel 111 through bolts, and the length direction of the channel steel 111 is perpendicular to the length direction of the rail 120. The positioning shaft 240 is fixedly connected to the two channel steels 111 through bolts, and the axial direction of the positioning shaft 240 is perpendicular to the length direction of the rail 120. The rotating member is a rotating sleeve 210, the rotating sleeve 210 is coaxially sleeved on the positioning shaft 240, and the rotating sleeve 210 can also rotate relative to the positioning shaft 240 along the axis thereof. The outer circumferential surface of the rotating sleeve 210 is welded with a connecting plate 211, and the connecting plate 211 penetrates the bottom plate 110 from the outer side of the rail 120 and then is welded with the car stopper 220.

Referring to fig. 1 and 2, the two channel steels 111 are further fixedly connected or welded with a pull rod 112 through bolts, and the pull rod 112 is disposed between the two positioning shafts 240. Each car stopper 200 is further provided with two first return springs 230, each first return spring 230 is an extension spring, one end of each first return spring 230 is hooked with the connecting plate 211, and the other end of each first return spring 230 is connected to the pull rod 112 through the adjusting assembly 300. Thus, the car stopper 220 always tends to move toward the inner side of the rail 120 by the first return spring 230.

Referring to fig. 2 and 3, a guide surface 221 is formed on an end surface of the car stopper 220 near the inner side of the rail 120, and the guide surface 221 is provided at a rear end in the moving direction of the car 400 when entering the cage. That is, when the mine car 400 enters the cage, the wheels 410 of the mine car 400 first abut against the guide surfaces 221 of the car stoppers 220. As the mine car 400 enters the cage, the car stop 220 gradually moves toward the outside of the rail 120 until the wheels 410 completely pass the guide surface 221. When the wheel 410 passes the car stop 220, the car stop 220 is moved toward the inner side of the rail 120 by the first return spring 230, and is stopped on the traveling path of the mine car 400.

Referring to fig. 2 and 4, the adjustment assembly 300 includes a first stud 310, a second stud 320, and a connecting ring 330 connecting the first stud 310 and the second stud 320. One end of the first stud 310 is welded or screwed on the pull rod 112, and one end of the second stud 320 is hooked with one end of the first return spring 230 far away from the car stop 220. One end of the connection ring 330 is threadedly connected to one end of the first stud 310 away from the drawbar 112, the other end of the connection ring 330 is threadedly connected to one end of the second stud 320 away from the first return spring 230, and the first stud 310 is threaded in the opposite direction to the second stud 320.

Since the first return spring 230 is lowered in elasticity after a long time use, the car stopper 220 cannot be completely returned. After the elastic force of the first return spring 230 is decreased, the connection ring 330 is rotated to make the first stud 310 and the second stud 320 approach each other, and the elastic force of the first return spring 230 is restored. Therefore, when the elastic force of the first return spring 230 is insufficient, the first return spring 230 does not need to be detached and replaced, and resources are saved.

Referring to fig. 1 and 3, an access opening 113 for accessing the car stopper 200 is formed on the bottom plate 110, and the access opening 113 faces the adjusting assembly 300. When the elastic force of the first return spring 230 is lowered, the service man can directly adjust the connection ring 330 from the service opening 113. Therefore, the maintainers do not need to adjust the connecting ring 330 at the bottom of the cage, the labor force is reduced, and the safety is improved. The bottom plate 110 is also fixedly connected with an access panel 114 for plugging the access opening 113 through bolts, and the access panel 114 is fixed on the bottom plate 110 when the access is not needed, so that the phenomenon that an operator steps empty from the access opening 113 is avoided, and the safety is further improved.

Referring to fig. 1 and 3, the car stopper 220 has a positioning groove 222 formed at a front end in a moving direction of the car 400 when the car 400 enters the cage, and the positioning groove 222 is fitted to a wheel 410 of the car 400. After the wheels 410 of the mine car 400 completely pass through the car blocking member 220 and the wheels 410 of the mine car 400 roll in the direction away from the cage, the wheels 410 of the mine car 400 are clamped in the positioning grooves 222, so that the car blocking member 220 is not easy to open, and the safety is improved.

When the wheels 410 of the mine car 400 roll away from the cage, but the wheels 410 of the mine car 400 are engaged in the positioning slots 222, the car stopper 220 is prone to being accidentally opened, which may cause a danger. Referring to fig. 2 and 5, in order to further reduce the probability that the car stopper 220 is accidentally opened, the rear end of the rotating sleeve 210 in the moving direction when the mine car 400 enters the cage is provided with a clamping groove 212, the positioning shaft 240 is integrally formed with a clamping block 241, and the rotating sleeve 210 can also slide relative to the positioning shaft 240 along the axis of the rotating sleeve. The positioning shaft 240 is coaxially sleeved with a second return spring 250, one end of the second return spring 250 is abutted to the rotating sleeve 210, the other end of the second return spring 250 can be abutted to the channel steel 111, and one end, far away from the rotating sleeve 210, of the second return spring 250 can also be abutted to other positions relatively fixed to the channel steel 111. In this embodiment, the positioning shaft 240 is further coaxially and integrally formed with a limiting block 242, and one end of the second return spring 250 away from the rotating sleeve 210 abuts against the limiting block 242.

When the wheels 410 of the mine car 400 roll in the direction away from the cage, but the wheels 410 of the mine car 400 are clamped in the positioning grooves 222, the wheels 410 of the mine car 400 can still push the car stop 220 to slide with the rotating sleeve 210, at the moment, the clamping blocks 241 are clamped with the clamping grooves 212, the rotating sleeve 210 cannot rotate relative to the positioning shaft 240 along the axis of the rotating sleeve, and the car stop 220 is stopped on the traveling path of the mine car 400.

The implementation principle of the cage with the car stopper 200 in the embodiment of the application is as follows:

when the mine car 400 enters the cage, the wheels 410 of the mine car 400 abut against the guide surfaces 221 of the car blocking members 220, and under the guiding action of the guide surfaces 221, the two car blocking members 220 are far away from each other, so that the mine car 400 enters the cage; when the mine car 400 is completely inserted into the cage, the two car blocking members 220 are moved toward each other by the first return spring 230, and are blocked in the traveling path of the mine car 400. When the mine car 400 has a tendency of leaving the cage, the wheels 410 are clamped in the positioning grooves 222, so that the car stopper 220 cannot be opened, the probability that the mine car 400 leaves the cage accidentally is reduced, and the safety is improved. After the force applied to the car stopping member 220 by the mine car 400 is transmitted to the rotating sleeve 210, the direction of the force is parallel to the axial direction of the rotating sleeve 210, so that the rotating sleeve 210 is not easy to bend and deform, and the probability of relative clamping of the rotating sleeve 210 and the positioning shaft 240 is reduced.

When the elastic force of the first return spring 230 is decreased, the car stopping member 220 may not be completely reset, at this time, the wheel 410 cannot be clamped into the positioning groove 222, and under the pushing action of the wheel 410, the rotating sleeve 210 slides along the axis of the rotating sleeve, so that the clamping block 241 is clamped with the clamping groove 212, thereby reducing the probability that the two car stopping members 220 move back to back. And when the wheel 410 fails to be normally locked in the positioning groove 222, the service person may open the service panel 114 and rotate the connection ring 330 to make the first stud 310 and the second stud 320 approach each other, thereby restoring the elastic force of the first return spring 230.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
