Problems solved by technology
[0003] When the vehicle stops suddenly due to inertia, it will continue to move forward, and will eventually be decelerated and stopped by the buffer bump on the cart. Therefore, when the buffer bumps of two driving carts collide, it will inevitably bring large vibrations and shocks, which will affect the Its detection accuracy and service life

Abstract
The invention discloses a travelling crane cart limiting device which comprises a first limiting device and a first fixed circular ring. The first fixed circular ring is fixedly connected to the sidewall of the first limiting device; a fixed block is fixedly connected to one end of the first limiting device; a second limiting device is arranged on one side of the first limiting device; a first fixed frame is fixedly connected to the upper end of the fixed block; a first buffer chamber is arranged on the side wall of the first fixed frame; a support rod is arranged under the first buffer chamber; a second spring is fixedly connected to the inner side wall of the first buffer chamber; a first round ball is fixedly connected to one end of the support rod; a T-shaped driving rod is fixedly connected to one end of the second spring; and a reflector plate is fixedly connected to one end of the T-shaped driving rod. According to the travelling crane cart limiting device provided by the invention, a third spring is used for compressing, so that the vibration of a vehicle on the first limiting device and the second limiting device during the driving process is reduced, and the working precision of the first limiting device is improved.
Description
technical field [0001] The invention relates to the technical field of traffic supplies, in particular to a limiting device for a trolley. Background technique [0002] At present, when a factory with more than three (including two) cranes on one span is in use, mutual limit devices must be installed between the cranes to ensure that when one crane is running, the operator will approach the other when the operator is not paying attention. It can stop automatically to avoid excessive collisions and unnecessary safety accidents. A photoelectric switch is installed on one drive, and a reflector is installed at the corresponding position on the adjacent drive. When the distance between adjacent drives reaches the set distance , the photoelectric switch receives the signal reflected by the reflector, and immediately triggers the control circuit connected to it to realize the power off of the vehicle; it uses the principle of blocking or reflecting the light beam by the detected o...
