[0017] Figure 2 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Example 1, please refer to Figure 1-2 , the utility model provides a technical solution:

[0020] The removal inspection and control device comprises a gear shaft 1, a gear for input motion is arranged at one end of the gear shaft 1, and a trapezoidal thread for output motion is arranged at the other end;

[0021] A telescopic sleeve 2 for converting axial motion is arranged on the trapezoidal thread, a guide seat 3 is arranged on the surface of the telescopic sleeve 2, and a limiting sleeve 4 is arranged at one end of the telescopic sleeve 2 close to the gear shaft 1.

[0022] like Figure 2 As shown: a bearing seat 5 is arranged on the gear. For coordinated use, a bearing for connecting the gear shaft 1 is installed inside the bearing seat 5 to facilitate bearing the gear shaft 1.

[0023] like Figure 2 As shown: an internal thread 1 that matches the trapezoidal thread is provided inside the telescopic sleeve 2 to facilitate connection and convert the rotational motion of the gear shaft 1 into axial motion.

[0024] like Figure 2 As shown: a bearing sleeve for matching the telescopic sleeve 2 is installed inside the guide seat 3 to facilitate supporting the telescopic sleeve 2.

[0025] like Figure 2 As shown: an inner hole thread 2 matching the trapezoidal thread is provided inside the limiting sleeve 4 to facilitate disassembly, assembly and maintenance.

[0026] like Figure 2 As shown: the device is also provided with three inspection positions 6, and the inspection position 6 is equipped with a travel switch, and the travel switch is equipped with a roller;

[0027] The outer circle of the telescopic sleeve 2 is provided with a guide keyway which cooperates with the roller.

[0028] The outer circle of the limiting sleeve 4 is provided with a chamfer that matches the roller, so as to facilitate the smooth combination with the roller on the switch.

[0029] Working principle:

[0030] The gear on the gear shaft 1 meshes with the transmission system of the mobile workbench through the gears to drive the gear shaft to rotate. The guide keyway on the telescopic sleeve 2 limits its own rotation while realizing the axial movement of the telescopic sleeve 2 through the internal spiral transmission with the gear shaft 1.

[0031] The outer structure of the limit sleeve 4 is convenient for the roller introduction of the travel switch, and the connection method between the inner hole thread 2 and the telescopic sleeve 2 can implement fine adjustment of the control point and facilitate later repair and maintenance.

[0032] The guide seat 3 and the bearing seat 5 are used to support the transmission system of the device.

[0033] Travel switches are provided at the three control positions 6 of deceleration (located on one side of the telescopic sleeve 2), stop (located on one side of the limit sleeve 4), and safety limit (located at one end 2 of the telescopic sleeve and aligned with it). The detection signal is used to control the motor, thereby meeting the movement requirements of the mobile workbench.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
