Travelling crane and boarding/alighting safety device of travelling crane

Abstract

The invention discloses a travelling crane and a boarding / alighting safety device of the travelling crane. The boarding / alighting safety device comprises a guide device (100), a connection rod (200) and a control switch (300). The guide device (100) is arranged at one side of a crawling ladder (400) of the travelling crane and extends along an extension direction of the crawling ladder (400). The connection rod (200) is slidingly arranged on the guide device (100). The top end of the connection rod (200) extends to the top of the crawling ladder (400) and the bottom end of the connection rod (200) extends to the bottom end of the crawling ladder (400). The connection rod (200) is provided with a stirring part (210). The control switch (300) is arranged at one side of the connection rod (200) provided with the stirring part (210) and is used for controlling travelling crane motor circuit on / off switching. The control switch (300) is a spring normally open switch. The stirring part (210) can produce interference with the control switch (300) along with connection rod (200) movement so that the stirring part (210) can apply a force for closing the control switch (300). The boarding / alighting safety device solves the problem that travelling crane maloperation causes braking failure so that a boarding person can be damaged because of crowding.

Description

technical field [0001] The invention relates to the technical field of driving, in particular to a safety device for driving and getting on and off the vehicle. Background technique [0002] Crane is a relatively common lifting equipment used for hoisting heavy objects. During the continuous work or inspection process of the crane, the operator or inspection personnel need to wait for the crane to stop before boarding the crane for work. When the driving is in the parking state, the driving cart is in the braking state. Once the operator makes a wrong operation, it is very easy to cause the brake to fail, which will cause the vehicle to release the brake and start moving again. Obviously, this is extremely likely to cause crushing injuries to boarding personnel. [0003] It can be seen that how to improve the safety of boarding personnel when driving is in a stopped state is a technical problem to be solved urgently by those skilled in the art.
