[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a shock-absorbing mechanism for an industrial elevator traction machine, comprising a base 1, mounting blocks 2 symmetrically and fixedly connected to both sides of the base 1, a mounting platform 3 provided above the base 1, a traction machine base plate 4 tightly inserted above the mounting platform 3, a traction machine body 5 fixedly connected above the traction machine base plate 4, the mounting platform 3 and the traction machine base plate 4 being connected by a connecting component 6, and the base 1 and the mounting platform 3 being connected by a shock-absorbing component 7.

[0024] Specifically, the connecting component 6 includes a bidirectional trapezoidal lead screw 61, a rotating block 62, a square slider 63, a drive plate 64, a fixing rod 65, and a limiting component 66. The bidirectional trapezoidal lead screw 61 is rotatably connected to the inside of the mounting platform 3 via bearings. One end of the bidirectional trapezoidal lead screw 61 passes through the mounting platform 3 and is fixedly connected to the rotating block 62. The surface of the bidirectional trapezoidal lead screw 61 is symmetrical and threadedly connected to the square slider 63. The square slider 63 and the mounting platform 3 are in close sliding connection. The drive plate 64 is fixedly connected above the square slider 63. The drive plate 64 and the mounting platform 3 are in sliding connection. A fixing rod 65 is fixedly connected to one side of the drive plate 64. The limiting component 66 is provided above the rotating block 62.

[0025] By adopting the above technical solution, rotating the rotating block 62 causes the bidirectional trapezoidal screw 61 to rotate. The rotation of the bidirectional trapezoidal screw 61 causes the square slider 63, which is symmetrically arranged on the surface, to move. This causes the square slider 63 to move the drive plate 64, thereby causing the fixing rod 65 to disengage from the fixing holes on both sides of the traction machine base plate 4. Then, the traction machine base plate 4 and the mounting platform 3 can be separated and removed for inspection and maintenance of the traction machine body 5.

[0026] Specifically, the limiting component 66 includes a gear 661, a support plate 662, a limiting screw 663, a toothed block 664, a guide slide rod 665, and a throttle 666. The gear 661 is fixedly connected to the rotating rod of the throttle block 62. The support plate 662 is fixedly connected to one end of the mounting platform 3. The limiting screw 663 is threaded to one end of the support plate 662. The toothed block 664 is rotatably connected to the lower part of the limiting screw 663. The toothed block 664 and the gear 661 are meshed. The throttle 666 is fixedly connected to the upper part of the limiting screw 663. The guide slide rod 665 is fixedly connected to one side above the toothed block 664. The guide slide rod 665 and the support plate 662 are slidably connected.

[0027] By adopting the above technical solution, after the rotating block 62 drives the fixing rod 65 to fix the traction machine base plate 4, the throttle 666 is rotated. The throttle 666 will drive the limiting screw 663 to rotate. Under the action of the guide slide rod 665, the tooth block 664 will move down and mesh with the gear 661, thereby limiting and fixing the rotating rod of the rotating block 62 and improving the stability after fixing.

[0028] Specifically, the surface of the rotating block 62 is surrounded and fixedly connected with rubber anti-slip strips.

[0029] By adopting the above technical solution, the rubber anti-slip strip makes it easy to rotate the rotating block 62, thus achieving an anti-slip effect.

[0030] In this embodiment, when in use: rotating the rotating block 62 causes the bidirectional trapezoidal lead screw 61 to rotate, which in turn causes the symmetrically arranged square sliders 63 to move. This causes the square sliders 63 to move the drive plate 64, thereby causing the fixing rod 65 to disengage from the fixing holes on both sides of the traction machine base plate 4. Then, the traction machine base plate 4 and the mounting platform 3 can be separated and removed for inspection and maintenance of the traction machine body 5. After the rotating block 62 drives the fixing rod 65 to fix the traction machine base plate 4, rotating the handle 666 causes the limit screw 663 to rotate. Under the action of the guide slide rod 665, the toothed block 664 moves down and meshes with the gear 661, thereby limiting and fixing the rotating rod of the rotating block 62, improving the stability after fixing. This allows the traction machine base plate 4 to be easily disassembled and assembled during use, and the structure has high stability.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the damping assembly 7 includes a damping seat 71, a damping telescopic rod 72, a damping spring 73, and a damping plate 74. The damping seat 71 is fixedly connected to the top of the base 1. The damping telescopic rod 72 is symmetrically and fixedly connected to both sides inside the damping seat 71. The damping spring 73 is sleeved on the surface of the damping telescopic rod 72. The damping plate 74 is fixedly connected to the top of the damping telescopic rod 72. The damping plate 74 and the damping seat 71 are slidably connected. The top of the damping plate 74 is fixedly connected to the mounting platform 3.

[0033] By adopting the above technical solution, the vibration of the device is reduced by moving the damping plate 74 in the damping seat 71 to compress the damping spring 73, and in conjunction with the damping telescopic rod 72.

[0034] Specifically, a rubber damping block 75 is fixedly connected in the middle inside the damping seat 71, and a rubber damping block 76 is fixedly connected in the middle below the damping plate 74.

[0035] By adopting the above technical solution, the rubber damping block 75 and the rubber damping block 76 are squeezed against each other, which facilitates further damping.

[0036] In this embodiment, the vibration of the device is reduced by moving the damping plate 74 in the damping seat 71 to compress the damping spring 73, which works in conjunction with the damping telescopic rod 72. The vibration of the device is reduced by the mutual compression of the rubber damping block 75 and the rubber damping block 76. The double damping makes the damping effect better, so the device can easily dampen the vibration encountered during use, resulting in a good damping effect.

[0037] The structure and operating principle of the base 1, mounting block 2, mounting platform 3, traction machine base plate 4, and traction machine body 5 in this utility model have been disclosed in a disassembled elevator traction machine shock absorption device disclosed in Chinese patent application number 202222640781.3. Its working principle is that the device is fixed in the position of use by the mounting block 2, and then connected by the traction machine base plate 4 and the mounting platform 3 to facilitate the installation and use of the traction machine body 5.

[0038] The working principle and usage process of this utility model: This utility model facilitates vibration reduction of the traction machine. In use, the device is fixed in the position by the mounting block 2, and then connected to the traction machine base plate 4 and mounting platform 3 for easy installation and use of the traction machine body 5. The traction machine base plate 4 and mounting platform 3 are fixed by the connecting component 6. During use, the vibration is reduced by the vibration damping component 7. When the traction machine body 5 needs to be disassembled for maintenance, it can be quickly disassembled and reassembled via the connecting component 6. When using the connecting component 6, rotating the rotating block 62 causes the bidirectional trapezoidal lead screw 61 to rotate. The rotation of the bidirectional trapezoidal lead screw 61 causes the symmetrically arranged square sliders 63 to move, which in turn causes the drive plate 64 to move, thereby causing the fixing rod 65 to disengage from the fixing holes on both sides of the traction machine base plate 4. Then, the traction machine base plate 4 and mounting platform 3 can be separated and removed. During the maintenance and repair of the traction machine body 5, after the rotating block 62 drives the fixing rod 65 to fix the traction machine base plate 4, the throttle 666 is rotated. The throttle 666 will drive the limit screw 663 to rotate. Under the action of the guide slide rod 665, the tooth block 664 will move down and mesh with the gear 661, thereby limiting and fixing the rotating rod of the rotating block 62, improving the stability after fixing. This allows the traction machine base plate 4 to be easily disassembled and assembled during use, and the structure has high stability. When the shock absorption component 7 is used, the shock absorption plate 74 moves in the shock absorption seat 71 to compress the shock absorption spring 73. In conjunction with the damping telescopic rod 72, the vibration of the device is reduced. The rubber shock absorption block 1 75 and the rubber shock absorption block 2 76 squeeze each other to facilitate further shock absorption. The double shock absorption makes the shock absorption effect better, and the device can easily perform double shock absorption on the encountered vibrations during use, resulting in a good shock absorption effect.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
