Travel switch used for of three-dimensional garage car-loading disc

Abstract

A travel switch used for of a three-dimensional garage car-loading disc comprises an elastic reset collision rod and an electrical trigger device box capable of matching with the elastic reset collision rod. The travel switch used for of the three-dimensional garage car-loading disc is characterized in that the elastic reset collision rod and the electrical trigger device box are respectively accommodated in an inner cavity of a closed travelling wheel box located on a base of the three-dimensional garage car-loading disc, a through hole is arranged on the top of the travelling wheel box, and the end portion of the elastic reset collision rod is penetrating arranged in the through hole and exposed outside the travelling wheel box. Compared with the prior art, the travel switch used for of the three-dimensional garage car-loading disc has the advantages that since both the elastic reset collision rod and the electrical trigger device box of the travel switch are accommodated in the travelling wheel box, a concealed travel switch structure is achieved, the electrical trigger device box and a trigger device of the travel switch can be protected effectively, the electrical trigger device box and the trigger device can be prevented from action of external impact force of a fixed stop iron and the like, reliability and safety of action of the stroke switch are guaranteed, accordingly failure-free operation time of the car-loading disc is extended greatly, and service life of the car-loading disc is prolonged.

Description

technical field [0001] The invention relates to a travel switch, in particular to a travel switch used for a car tray in a three-dimensional garage. Background technique [0002] At present, the traversing vehicle tray of the three-dimensional garage includes a base with a wheel box. The wheel box is provided with a wheel transmission shaft. Shift; there is a travel switch on one side of the base, the travel switch includes an elastic reset ram and an electrical trigger box, when the vehicle-carrying plate moves laterally in place, the fixed stop iron collides with the elastic reset ram, and the elastic reset ram is connected with the electric trigger box. The contacts of the triggering device box contact, so that the travel switch acts, and the vehicle-carrying disc is in place, so that the vehicle in the vehicle-carrying disc can be driven out or driven in. [0003] However, most of the travel switches of the existing vehicle-carrying discs adopt an exposed installation s...

Problems solved by technology

[0003] However, most of the travel switches of the existing vehicle-carrying discs adopt an exposed installation structure, that is, the elastic reset striker of the travel switch and the electrical trigger box are all exposed and installed on the vehicle-carrying disc base or on the corresponding components, without sealing and protection. In addition, most of them use a structural design in which the moving parts directly hit the travel switch, so that the external impact force is directly applied to the travel switch, which is not conducive to the effective protection of the travel switch as a whole, thus affecting the reliability of its operation. Safety and safety; secondly, due to the limit switch installed on the vehicle-carrying plate, it will frequently be subjected to impact loads during the movement of the car-carrying plate. For the exposed electrical trigger device box, it is vulnerable to external environmental factors, etc. Interference, especially vulnerable to external force collisions, poor safety protection performance, because the electrical trigger box is damaged, it is easy to cause the action of the travel switch to fail, which in turn leads to the failure of the vehicle-mounted disk
