Description

Technical Field

[0001] The utility model belongs to the technical field of brackets, and particularly relates to a fixed bracket for a magnetic control switch of a blind main shaft wellbore. Background Art

[0002] A magnetic control switch is a switch control device with a wide range of uses. In the structure and operation of an elevator, a large number of sensors and various passage control structures are required to realize the corresponding operation and attitude control of the elevator, and the switch fixed bracket is an in-well bracket for installing the magnetic control switch.

[0003] The existing magnetic control switch is only fixed in position by being installed on an angle steel. However, when the magnetic control switch is installed in a well, there is a hidden danger of being damaged by falling objects. Content of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model provides the following technical solutions:

[0005] The fixed bracket for the magnetic control switch of the blind main shaft wellbore includes an angle steel and a magnetic valve switch installed on the angle steel. Two groups of support columns are hinged to the bottom end of the magnetic valve switch, and the bottom ends of the support columns are connected to a first slider. The first sliders all slide on the outer wall of a slide bar, and the slide bar is installed in a limit groove. The limit groove is opened at the top end of the angle steel. The two first sliders are connected by an elastic member, and the middle part of the elastic member surrounds the outer wall of the slide bar.

[0006] The magnetic valve switch is installed on the angle steel under the action of the elastic mechanism. When the magnetic valve switch is damaged by falling objects, under the combined action of the elastic mechanism, the magnetic valve switch is buffered to avoid the situation that the traditional magnetic valve switch and the angle steel are rigidly connected and broken due to falling objects.

[0007] Preferably, a second slider is installed in the magnetic valve switch, and the second sliders all slide in slide rails. The slide rails are symmetrically opened on the outer wall of the angle steel.

[0008] When the magnetic valve switch elastically buffers on the angle steel under the support of the support columns and the elastic potential energy of the elastic member, the stability of the movement of the magnetic valve switch under the sliding cooperation of the second slider and the slide rail is guaranteed.

[0009] Preferably, balls are rollingly embedded at the top end of the outer wall of the angle steel, and the outer walls of the balls rollingly abut against the inner wall of the magnetic valve switch.

[0010] Under the rolling action of the balls, combined with the elastic mechanism and the sliding action of the second slider and the slide rail, the smoothness efficiency of the movement of the magnetic valve switch on the outer wall of the angle steel is further improved.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In this application, the magnetic valve switch is installed on the angle steel under the action of the elastic mechanism. When the magnetic valve switch is damaged by falling objects, it is buffered by the elastic mechanism, thus avoiding the situation that the traditional magnetic valve switch and the angle steel are rigidly connected and broken due to falling objects.

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] In view of the problem that the magnetic control switch in the prior art is damaged by falling objects when installed in the well, the magnetic valve switch 2 is installed on the angle steel 1 under the action of the elastic mechanism. When the magnetic valve switch 2 is damaged by falling objects, it is buffered by the elastic mechanism, thus avoiding the situation that the traditional magnetic valve switch 2 and the angle steel 1 are rigidly connected and broken due to falling objects.

[0020] As Figure 1 and Figure 2 shown, in the embodiment of the present utility model, the fixed bracket for the magnetic control switch of the blind main shaft includes the angle steel 1 and the magnetic valve switch 2 installed on the angle steel 1; this is well known to those skilled in the art and will not be elaborated in this application.

[0021] As Figure 2 and Figure 3As shown in the figure, two sets of support columns 3 are hinged to the bottom end of the solenoid valve switch 2, and the bottom ends of the support columns 3 are connected to the first sliders 4. The first sliders 4 are all slidably arranged on the outer wall of the slide bar 5. The slide bar 5 is installed in the limit groove 6, and the limit groove 6 is opened at the top end of the angle steel 1. The two first sliders 4 are connected by an elastic member 7, and the middle part of the elastic member 7 surrounds the outer wall of the slide bar 5. When an object falls on the top end of the solenoid valve switch 2, at this time, under the elastic potential energy of the elastic member 7, the sliding action of the first slider 4 and the slide bar 5, and the supporting action of the support column 3, an elastic buffering action is carried out at the top end of the angle steel 1, avoiding the situation that the traditional solenoid valve switch 2 and the angle steel 1 are rigidly connected and broken due to the falling object; A second slider 9 is installed in the solenoid valve switch 2, and the second sliders 9 are all slidably arranged in the slide rails 10. The slide rails 10 are symmetrically opened on the outer wall of the angle steel 1; When the solenoid valve switch 2 performs elastic buffering on the angle steel 1 under the support of the support column 3 and the elastic potential energy of the elastic member 7, the stability of the movement of the solenoid valve switch 2 is guaranteed under the sliding cooperation of the second slider 9 and the slide rail 10; The outer wall of the top end of the angle steel 1 is rollingly embedded with a ball 8, and the outer wall of the ball 8 is rollingly abutted against the inner wall of the solenoid valve switch 2; Under the rolling action of the ball 8, the elastic mechanism, and the sliding action of the second slider 9 and the slide rail 10, the smoothness efficiency of the movement of the solenoid valve switch 2 on the outer wall of the angle steel 1 is further improved.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
