Description

Switching mechanism for traction machine

Technical Field

The utility model relates to a hauler stopper technical field, especially a switching mechanism for hauler.

Background

At present, the microswitch used by the tractor brake used in the market is generally in a direct triggering type, and a small part of the microswitch is also in a reed type. The requirement on the clearance of the directly triggered microswitch is very high, if the clearance of the brake is improperly controlled, the sensitivity of the microswitch is reduced, finally the microswitch is failed, and the action of the brake cannot be judged; the microswitch adopting the reed type has high requirements on the service life and the reliability of the reed, and the reed can deform and the like in the actual use process, so that the microswitch finally fails.

The application discloses a microswitch for a tractor, which has the defects that a shifting lever of a switch mechanism is not provided with a rebound device, the locking condition is easy to occur, the stability is not high, the shifting lever and an adjusting bolt are in linear contact, a contact is easy to wear, finally, the action of the microswitch has errors, and the sensitivity is reduced. Therefore, it is urgently needed to develop a microswitch for a traction machine with higher stability and sensitivity to meet the market demand.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a switching mechanism for hauler. The novel LED lamp has the advantages of compact overall structure, high stability, good flexibility and more reliable use.

The technical scheme of the utility model: a switch mechanism for a tractor comprises a mandril arranged on a brake armature component and a microswitch component arranged on a brake electromagnet component, wherein the microswitch component comprises a bracket, a microswitch body is arranged on the bracket, a contact is arranged on the microswitch body, a lever is arranged on one side of the contact, and the lever is rotatably connected with the bracket through the matching of a pin shaft and a torsional spring; the support includes that the support lateral wall that carries on spacingly to the lever is equipped with the passageway that supplies the ejector pin to pass on the support lateral wall.

In the switch mechanism for the traction machine, the micro switch assembly is rigidly connected with the electromagnet assembly of the brake.

In the aforementioned switch mechanism for a hoisting machine, the lever is made of a rigid material.

In the switch mechanism for the traction machine, the microswitch body is fixed with the bracket through the fixing screw.

Compared with the prior art, the microswitch component of the utility model is rigidly connected on the electromagnet component of the brake, wherein, the microswitch component comprises a bracket, a microswitch body is arranged on the bracket, a contact is arranged on the microswitch body, a lever is arranged at one side of the contact, the lever is rotationally connected with the bracket through the matching of a pin shaft and a torsional spring, the microswitch body and the lever are orderly arranged on the bracket, the whole structure is compact, when the brake is powered on, the ejector rod props against the middle part of the lever, the lever rotates around the pin shaft, so that the tail end of the lever contacts with the contact on the microswitch body, when the brake is powered off, the lever rebounds and resets under the action of the torsional spring, the lever can not generate the phenomenon of locking, the stability and the reliability are both good, after the utility model is powered on or powered off, the lever can rapidly move to contact or keep away from the contact, the sensitivity is high; the support includes that the support lateral wall that carries on spacingly to the lever makes the lever be in same position all the time when the stopper outage, is equipped with the passageway that supplies the ejector pin to pass on the support lateral wall, makes the ejector pin can directly act on the lever.

In addition, the microswitch assembly is rigidly connected with the electromagnet assembly of the brake, the lever is made of rigid materials, and the microswitch body is fixed with the support through the fixing screw, so that the stability of the mechanism operation is improved.

To sum up, the utility model has the advantages of compact integral structure, high stability, good flexibility and more reliable use.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example (b): a switch mechanism for a tractor is structurally shown in figures 1 to 4 and comprises a mandril 2 arranged on a brake armature component 1 and a microswitch component 4 arranged on a brake electromagnet component 3, wherein the microswitch component 4 comprises a bracket 41, a microswitch body 42 is arranged on the bracket 41, a contact 421 is arranged on the microswitch body 42, a lever 43 is arranged on one side of the contact 421, and the lever 43 is rotatably connected with the bracket 41 through the matching of a pin shaft 44 and a torsion spring 45; the bracket 41 comprises a bracket side wall 411 for limiting the lever 43, and a channel for the mandril 2 to pass through is arranged on the bracket side wall 411.
