Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Examples

As shown in figure 1, the application provides a rail trolley limiting mechanism which is arranged on one side of a trolley track 12 and is convenient for limiting a trolley of a transportation clamp in the transportation process. This stop gear includes base 1, connection platform 2 and the tray 8 that from the bottom up set gradually. The connecting table 2 is fixed on the base 1. A V-shaped groove is arranged in the middle of the supporting block 8, and inclined planes which incline downwards are respectively arranged on two sides of the supporting block along the extending direction of the track 12 and are used as guide planes. The lower side of the carrier block 8 is supported above the connecting table 2 by means of a telescopic shaft 7 and a spring 6. A supporting rod 4 fixed in the connecting table 2 is arranged in the spring 6, a fixed stop block 5 is arranged at the top of the supporting rod 4, and a supporting block 8 is sleeved on the supporting rod 4 and is limited below the fixed stop block 5. The lower end of the telescopic shaft 7 is fixed in the connecting table 2 through a fixed shaft sleeve 3.

A moving stop 9 is arranged between the upper side of the supporting block 8 and the fixed stop 5. A gasket 10 is arranged between the upper side of the supporting block 8 and the moving stop 9. When the limiting mechanism is in a non-working state, as shown in fig. 2, the position of the moving stop 9 influenced by the tension of the spring 6 is limited by the fixed stop 5 arranged on the support rod 4, so that the height of the support block 8 is ensured, and the height of the support block 8 can be adjusted by the gasket 10. The connecting platform 2 is connected to the base 1 through the round large hole, and the error of the connecting platform 2 in the direction can be adjusted through the position of the round large hole, so that the coordination of one or more limiting mechanisms during the joint work is ensured.

In this embodiment, two support rods 4 are arranged in the middle of the connecting platform 2, and are respectively sleeved with springs 6. The telescopic shaft 7 is also provided with two, one on each side of the spring 6 in the direction of extension of the rail 12.

The working principle of the limiting mechanism is as follows:

as shown in fig. 3, when the trolley runs to the limiting mechanism, the outer edge of the trolley wheel 11 is contacted with the guide surface of the supporting block 8; as shown in fig. 4, as the wheels 11 of the trolley move along the guide surface, a downward force is applied to the supporting block 8, the force is transmitted to the spring 6, so that the spring 6 is compressed, and the telescopic shafts 7 on the two sides orderly and synchronously act in the fixed shaft sleeve 3 in the process, thereby ensuring the levelness of the whole supporting block 8;

as shown in fig. 5 and 6, when the trolley wheel 11 moves away from the highest position of the support block 8, under the influence of the downward slope of the middle V-shaped groove of the support block 8, the spring 6 is extended upward while entering the space generated by the middle V-shaped groove of the support block 8, the support block 8 is ejected upward, and the trolley wheel 11 is limited in the V-shaped groove at this time.

After the limiting time period, the trolley wheels 11 can move upwards along the V-shaped grooves of the supporting blocks 8 by applying a force to get rid of the limiting space and get away from the limiting mechanism.
