DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0020] The following describes an embodiment of the utility model based on its overall structure.

[0021] An elevator traction sheave maintenance device, such as Figure 1-Figure 3 As shown, it includes a bottom plate 1 and a support spring 11, a scale plate 6 is arranged on one side of the top of the bottom plate 1, a mounting frame 9 is arranged on the other side of the top of the bottom plate 1, a sliding seat 10 is slidably connected to the top of the mounting frame 9, a roller 12 is rotatably connected to the inner side of the sliding seat 10, a sliding frame 8 is arranged on one side of the sliding seat 10, a pointer 7 is arranged on the right side of the front end of the sliding frame 8, a support spring 11 is arranged between the sliding seat 10 and the mounting frame 9, and the sliding seat 10 and the mounting frame 9 form an elastic structure through the support spring 11;

[0022] See also Figure 1-Figure 3 It can be seen that the bottom plate 1 is installed below the external traction wheel, and under the action of the support spring 11, the roller 12 is always in one-to-one contact with the rope groove, the traction wheel is moved by external power, and the traction wheel moves the roller 12 through the rope groove. In the process of vertical movement of the roller 12, the sliding frame 8 and the pointer 7 move together, so that the wear degree of the rope groove can be judged by the direction of the pointer 7 on the scale plate 6.

[0023] See also Figure 2 It can be seen that a limiting hole 5 is provided inside the first vertical plate 301, and a limiting rod 4 penetrating the limiting hole 5 is welded to the side of the second vertical plate 303 close to the first vertical plate 301. The second vertical plate 303 and the first vertical plate 301 form a sliding structure through the limiting hole 5 and the limiting rod 4. Two limiting holes 5 and two limiting rods 4 are symmetrically arranged about the central axis of the first vertical plate 301, which can play a supporting and limiting role, thereby increasing the stability of the second vertical plate 303 during sliding and preventing the second vertical plate 303 from deflecting during sliding.

[0024] See also Figure 1-Figure 3It can be seen that the top of the scale plate 6 is provided with a support frame 2, and the front end of the support frame 2 is provided with a positioning mechanism 3, and the positioning mechanism 3 includes a first vertical plate 301, an electric push rod 302 and a telescopic spring 305. The first vertical plate 301 is arranged at the front end of the support frame 2, and one side of the first vertical plate 301 is movably connected with a second vertical plate 303, and a positioning rod 304 is penetrated inside the second vertical plate 303. A positioning groove 306 is opened on the side of the pointer 7 close to the positioning rod 304. An electric push rod 302 connected to the second vertical plate 303 is installed inside the first vertical plate 301, and the pointer 7 and the second vertical plate 303 form a clamping structure through a positioning groove 306 and a positioning rod 304. A telescopic spring 305 is welded and connected between the positioning rod 304 and the second vertical plate 303. An inclined surface is provided at one end of the positioning rod 304 close to the pointer 7. The positioning rod 304 and the second vertical plate 303 form a sliding structure through a through hole. The positioning rod 304 is set as an inverted "T" structure;

[0025] See also Figure 1 and Figure 2 It can be seen that since the positioning rod 304 is elastically connected to the second vertical plate 303 through the telescopic spring 305, and the end of the positioning rod 304 close to the pointer 7 is provided with an inclined surface, during the wear degree measurement process, the pointer 7 will move in the vertical direction, and at the same time, the positioning rod 304 will be stuck in the positioning groove 306 under the action of the telescopic spring 305, thereby realizing the positioning of the pointer 7, so that personnel can accurately record the scale value, thereby facilitating accurate and rapid judgment of the wear degree of the rope groove. After the scale value is recorded once, the electric push rod 302 works and contracts, so that the positioning rod 304 is separated from the positioning groove 306. After the pointer 7 is reset, the positioning rod 304 is reset to facilitate measurement again, which is more convenient and accurate.

[0026] The working principle of the utility model is as follows: when the elevator traction sheave maintenance device is used, the bottom plate 1 is installed under the external traction sheave, and under the action of the supporting spring 11, the roller 12 is always in one-to-one contact with the rope groove, the traction sheave is moved by the external power, and the traction sheave moves the roller 12 through the rope groove. In the process of the vertical movement of the roller 12, the sliding frame 8 and the pointer 7 move together, so that the wear degree of the rope groove can be judged by the direction of the pointer 7 on the scale plate 6. In this process, the positioning rod 304 will be stuck in the positioning groove 306 under the action of the telescopic spring 305, so as to realize the positioning of the pointer 7, so that the personnel can record the accurate scale value, so as to facilitate the accurate and rapid judgment of the wear degree of the rope groove. After the scale value is recorded once, the electric push rod 302 works and contracts, so that the positioning rod 304 is separated from the positioning groove 306. After the pointer 7 is reset, the positioning rod 304 is reset so as to measure again, which is more convenient and accurate. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
