[0002] The existing rail trolley can carry prefabricated components and flow between different workstations according to process requirements. It is mainly used for the flow of prefabricated components in the production process of the assembly line. The rail trolley consists of a frame, a driving wheel group, a driven wheel group, an electronic control system, a prefabricated component bottom mold, etc. The main working principle is: the main driving wheel group and the driven wheel group are arranged in two rows along the trolley track to support the frame. The prefabricated component bottom mold is installed on the plane of the main beam of the frame. The rail trolley is driven by the reduction motor configured by the driving wheel group. The electronic control system is used to control the start and stop of the rail trolley. Because the prefabricated components carried by the rail trolley are heavy and long in size, when the rail trolley runs on a fixed track, there will inevitably be wheel slippage caused by factors such as trolley deformation, uneven track, and uneven load, and even wheel suspension, which will cause the rail trolley to be unable to flow, the production line to run poorly, and affect production efficiency. For this reason, it is necessary to provide an adaptive drive system for a rail trolley. Utility Model Content

DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown:

[0015] The utility model is an adaptive driving system for a rail trolley, comprising a rail trolley consisting of a frame 1, a driving wheel box 2, a driven wheel group 3, an electronic control system, and a prefabricated component bottom mold 4. A main driving wheel group 5, a driven wheel 6, and a reduction motor 7 are arranged in the driving wheel box 2. The main driving wheel group 5 and the reduction motor 7 are adjustably installed with the driving wheel box 2. The main driving wheel group 5 and the driven wheel group 3 are evenly arranged in two rows along the length direction of the bottom of the frame 1 to support the frame 1; the prefabricated component bottom mold 4 is fixedly installed on the plane of the main beam of the frame 1, the rail trolley relies on the reduction motor 7 to drive the main driving wheel group 5 to achieve walking, and the electronic control system is used to control the start and stop of the rail trolley; one side of the driving wheel box 2 adjusts the main driving wheel group 5 and the reduction motor 7 through the elastic action of the adaptive device 11, so that the reduction motor 7 drives the walking to always fit closely with the track.

[0016] In at least one embodiment, the adaptive device 11 includes a disc spring bracket 12, a support screw 13, a clamping nut 14, a lock nut 15, and a disc spring 16. The disc spring bracket 12 is welded to the driving wheel housing 2. The support screw 13 passes through the frame hole and the disc spring 16 in sequence on the disc spring bracket 12. The upper end of the support screw 13 passes through the disc spring 16 and is supported on the main beam of the frame 1. The upper end of the support screw 13 is threadedly installed with the lock nut 15 and the clamping nut 14 in sequence from top to bottom.

[0017] In at least one embodiment, the driving wheel box 2 is installed at the bottom of the frame 1 through the axle box 17, and a main driving wheel set 5 is arranged on the side of the driving wheel box 2 in the direction of travel. The main driving wheel set 5 is driven by a reduction motor 7, and a driven wheel 6 is arranged on the side of the driving wheel box 2 away from the main driving wheel set 5.

[0018] In at least one embodiment, at least four sets of driving wheel boxes 2 are symmetrically arranged on both sides of the bottom length direction of the frame 1. In this embodiment, four sets of driving wheel boxes 2 are used, which are evenly distributed on both sides of the bottom length direction of the frame 1.

[0019] The structural principle of the adaptive device is as follows: the disc spring bracket 12 of the adaptive device is welded to the driving wheel housing 2, the support screw 13 passes through the frame hole opened on the disc spring 16 support and the inner hole of the disc spring 16 in sequence, the upper end of the support screw 13 is supported on the main beam of the frame 1, and the upper end of the support screw 13 is threadedly installed with a locking nut 15 and a clamping nut 14 in sequence from top to bottom, and the clamping nut 14 is tightened. The locking nut 15 is used to prevent loosening. When the rail trolley runs on the track, if the wheel slips due to factors such as the deformation of the trolley, uneven track, and uneven load, or even when the wheel is suspended in the air, the disc spring 16 presses down on the disc spring bracket 12, thereby providing downward pressure for the main driving wheel group 5, so that it generates sufficient positive pressure with the track to prevent the wheel from slipping and idling. Within the adjustment range of the disc spring, the main driving wheel group 5 relies on this adaptive device to keep the driving wheel in close contact with the track at all times, ensuring the normal operation of the rail trolley.

[0020] The embodiments of the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent alternatives that can be thought of by those skilled in the art are all within the protection scope of the present invention.
