Crane trolley anticollision device

Abstract

The invention relates to a crane trolley anticollision device which comprises a fixed seat; a mounting seat is connected to the right part of the fixed seat in a clamping manner; a guide shaft is arranged at the left part of the mounting seat; the other end of the guide shaft is connected with the fixed seat through a nut; a spring is connected to the outer wall of the middle part of the guide shaft in a sleeving manner; one end of the spring is connected with the mounting seat; the other end of the spring is connected with the fixed seat; an anticollision block is connected to the right partof the mounting seat in the clamping manner; a distance measurement device is arranged on the upper side surface of the fixed seat and is provided with a controller; an ultrasonic emission module, a display, an alarm and an ultrasonic receiving module are connected to the output end of the controller through signal wires respectively; and a press key module is connected to the input end of the controller through a signal wire. The crane trolley anticollision device provided by the invention has the advantages of reasonable structure, convenience in use, high safety performance and low runningcost.

Description

technical field [0001] The invention belongs to the technical field of crane equipment, and in particular relates to an anti-collision device for a crane trolley. Background technique [0002] The crane trolley is an important part of the lifting device of the crane. The crane trolley is set on the main girder of the crane and walks on the track on the main girder of the crane to realize the lateral movement of the lifting object. During the braking process of the crane trolley, usually, Due to the effect of inertia, the limit device will be collided. Long-term collision will not only cause damage to the limit device and increase maintenance costs, but also cause damage to the crane trolley. At present, the crane trolley is usually operated by the operator Observe the start and stop, resulting in unreasonable stop position of the crane trolley, resulting in relatively large impulse force on the anti-collision device due to excessive inertia, and the existing anti-collision d...

[0002] The crane trolley is an important part of the lifting device of the crane. The crane trolley is set on the main girder of the crane and walks on the track on the main girder of the crane to realize the lateral movement of the lifting object. During the braking process of the crane trolley, usually, Due to the effect of inertia, the limit device will be collided. Long-term collision will not only cause damage to the limit device and increase maintenance costs, but also cause damage to the crane trolley. At present, the crane trolley is usually operated by the operator Observe the start and stop, resulting in unreasonable stop position of the crane trolley, resulting in relatively large impulse force on the anti-collision device due to excessive inertia, and the existing anti-collision device structure is unreasonable, and the buffering effect is not obvious. In addition, when the crane trolley appears The trolley cannot be stopped in time after a failure, which will cause a major impact on the anti-collision device and may cause a greater accident. For this, a crane trolley anti-collision system with reasonable structure, convenient use, high safety performance and low operating cost is provided. device is very important
