[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0027] Please see Figures 1-4This utility model embodiment provides an energy-saving traction machine for elevator construction, including a traction machine body 1, which is an energy-saving electric motor. The electric motor is the power source of the traction machine and drives the traction wheel to rotate through a gearbox or direct drive. A lubrication mechanism 2 is provided on the back of the traction machine body 1.

[0028] The lubrication mechanism 2 includes a traction drum 201. The front of the traction drum 201 is fixedly connected to the output end of the traction machine body 1. A stabilizing bearing 202 is provided on the back of the traction machine body 1. The inner ring of the stabilizing bearing 202 is fixedly connected to the outer surface of the traction drum 201. A mounting bracket 203 is fixedly connected to the upper surface of the stabilizing bearing 202. Two compression springs 204 are fixedly connected to the bottom surface of the mounting bracket 203. The bottom ends of the two compression springs 204 are fixedly connected to a lubrication box 205. The back of the lubrication box 205 is in contact with the front of the stabilizing bearing 202. The bottom surface of the lubrication box 205 is in contact with the outer surface of the traction drum 201. A sliding groove 206 is provided on the bottom surface of the lubrication box 205.

[0029] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 A cooling component 3 is provided on the back of the traction machine body 1, and a mounting and fixing component 4 is provided below the cooling component 3. The cooling component 3 includes a gearbox 302, which is a mechanical device used to change the speed and torque of power transmission. It is commonly used in automobiles, motorcycles, bicycles and other mechanical equipment that require power transmission. The main function of the gearbox 302 is to adjust the speed and torque output of the engine by changing the gear ratio to adapt to different driving conditions and needs, thereby facilitating the output of high-speed power by the gearbox 302. The front of the gearbox 302 is fixedly connected to the front of the stabilizing bearing 202. The traction drum 201 is rotatably connected to the inside of the gearbox 302. A rotating fan blade 303 is fixedly connected to the output end of the gearbox 302. The high-speed power output by the gearbox 302 can drive the rotating fan blade 303 to rotate at high speed, thereby facilitating the airflow near the wire rope by the high-speed rotating fan blade 303.

[0030] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 A wind baffle ring 301 is fixedly connected to the outer surface of the traction drum 201. The front of the mounting bracket 203 contacts the back of the wind baffle ring 301. The wind baffle ring 301 can conveniently block the flowing wind, thereby accelerating the airflow near the wire rope. It can also block the winding and unwinding of the wire rope, thereby improving the winding and unwinding stability of the wire rope.

[0031] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3The mounting and fixing assembly 4 includes a mounting base plate 401. The bottom surface of the traction machine body 1 and the outer ring of the stabilizing bearing 202 are fixedly connected to the upper surface of the mounting base plate 401. By using the mounting base plate 401 to set in the required position, the traction machine can be stably fixed in the required position using the mounting structure.

[0032] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The upper surface of the mounting base plate 401 is provided with two sets of mounting threaded holes 402. Each set of mounting threaded holes 402 is threaded with a mounting bolt 403. The bottom ends of the two sets of mounting bolts 403 pass through the two sets of mounting bolts 403 and extend to the bottom of the mounting base plate 401. By drilling holes corresponding to the mounting threaded holes 402 at the required positions, the mounting bolts 403 can be easily threaded through the mounting threaded holes 402 and connected to the drilled holes, thereby fixing the mounting base plate 401 in the required position.

[0033] Please refer to this carefully. Figure 1 Figure 2 Figure 3 Figure 1 Each set of mounting bolts 403 has a compression spring 404 fixedly connected to its outer surface, and an impact ring 405 fixedly connected to the bottom end of each set of compression springs 404. The inner walls of the two sets of impact rings 405 are in contact with the outer surfaces of the two sets of mounting bolts 403, and the bottom surface of each set of impact rings 405 is in contact with the upper surface of the mounting base plate 401. The compression springs 404 fixed on the impact rings 405 facilitate the compression of the compression springs 404 by twisting the mounting bolts 403. The elastic force inside the compression springs 404 can be used to improve the installation stability of the mounting bolts 403.

[0034] When using this utility model: First, connect the main body 1 of the traction machine to the power supply. When the energy-saving traction machine is to be used for elevator construction, first manually place the mounting base plate 401 of the traction machine in the required position, and drill holes corresponding to the mounting thread holes 402 in the required position. This allows the mounting bolts 403 to pass through the mounting thread holes 402 so that the mounting base plate 401 can be firmly fixed in the required position.

[0035] By continuing to twist the mounting bolt 403, the impact ring 405 can compress the compression spring 404 fixed to the outside of the mounting bolt 403 until the compression spring 404 reaches its maximum compression. When the traction machine vibrates during operation, the mounting bolt 403 may loosen due to the vibration. The compression spring 404 installed outside the mounting bolt 403 can then be used to firmly connect the mounting bolt 403 to the mounting base plate 401, thereby further improving the installation stability of the traction machine.

[0036] Next, one end of the wire rope of the traction machine is manually connected to the elevator, so that the wire rope is wound around the traction drum 201 fixed at the output end of the traction machine body 1. By controlling the power supply of the traction machine body 1, the traction machine body 1 can drive the traction drum 201 to rotate. The traction drum 201 can output high-speed rotation power in the gearbox 302, which can facilitate the high-speed rotation of the rotating fan blade 303. The high-speed rotating fan blade 303 can accelerate the air flow of the wire rope outside the traction drum 201, thereby accelerating the cooling of the wire rope.

[0037] Meanwhile, the mounting bracket 203, which is fixed externally to the stabilizing bearing 202, can fix the lubrication box 205 to the outside of the traction drum 201 by means of two compression springs 204. This allows the wire rope to slide in the sliding groove 206 opened under the lubrication box 205, thereby continuously applying lubricating oil to the outside of the wire rope, reducing the friction of the wire rope and extending the service life of the traction machine.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
