Description

A kind of device of quick-detachment encoder

Technical field

The utility model relates to a kind of dismounting encoder implementation, particularly a kind of device for quick-detachment elevator traction machine rotary encoder.

Background technology

Along with the fast development in home lift market in recent years, the maintenance of elevator seems extremely important and crucial, especially the core component traction machine of elevator, and traction machine needs the parts changed to be exactly rotary encoder often.Often can there is at building-site the situation cannot taking out encoder, stop over maintenance progress, have impact on use.

Utility model content

Technical problem to be solved in the utility model to provide a kind of energy easy and simple to handle, the device of quickness and high efficiency ground quick-detachment encoder.

In order to solve above technical problem, the utility model provides a kind of device of quick-detachment encoder, described device is L-type, minor face is handle, and long limit is telescopic shaft, and termination, long limit is the externally threaded thread head of band, shaft has pushing block near handle place cover, the inner bolt hole of thread head and rotary encoder inside is spirally connected, and pushing block post-tensioning knocks handle, takes out the rotary encoder be embedded in traction machine.

Described thread head and shaft are flexibly connected.

Described pushing block and shaft are flexibly connected, the weight of replaceable pushing block and size.

Described handle and shaft are flexibly connected.

Operation principle of the present utility model: the internal thread hole being tightened rotary encoder inside by the thread head of shaft end, make shaft and rotary encoder fixation, then pull back to handle by pushing block, pull back handle, by reaction force, realize the dismounting to rotary encoder.

Superior effect of the present utility model is: for the dismounting of embedded rotary encoder, realizes quick-detachment rotary encoder, and effectively protects rotary encoder and do not damage in unloading process.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.

Fig. 1 shows schematic diagram of the present utility model, and Fig. 2 shows front view of the present utility model, and Fig. 3 shows specific embodiment of the utility model figure.As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of device of quick-detachment encoder, described device is L-type, and minor face is handle 4, and long limit is telescopic shaft 2, termination, long limit is the externally threaded thread head 1 of band, shaft 2 has pushing block 3 near handle place cover, and thread head 1 is spirally connected with the inner bolt hole of rotary encoder 6 inside, and pushing block 3 post-tensioning is to handle 4, pushing block 3 knocks handle 4 backward, takes out the rotary encoder 6 be embedded in traction machine 5.

Described thread head 1 is be flexibly connected with shaft 2, changes thread head easy.

Described pushing block 3 is be flexibly connected with shaft 2, the weight of replaceable pushing block and size.

Described handle 4 is be flexibly connected with shaft 2, changes handle easy.

Operation principle of the present utility model: the internal thread hole being tightened rotary encoder 6 inside by the thread head 1 of shaft end, make shaft 2 and rotary encoder 6 fixation, pull back to handle 4 by pushing block 3 again, pushing block 3 knocks handle 4 backward, by reaction force, realize the dismounting to rotary encoder 6.

The foregoing is only preferred embodiments of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., within all should being included in protection domain of the present utility model.
