Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and specifically relates to a traction device for an elevator machine room. Background Art

[0002] An elevator traction machine is the power equipment of an elevator, also known as the elevator main engine. Its function is to transmit and transfer power to make the elevator operate. It consists of a motor, a brake, a coupling, a speed reducer, a traction wheel, a machine frame, a guide wheel, and an attached handwheel for disk operation, etc. The guide wheel is generally installed on the machine frame or the load-bearing beam under the machine frame. The handwheel for disk operation is either fixed on the motor shaft or usually hung on the nearby wall and then sleeved on the motor shaft when in use. During the long-term operation of the elevator traction machine speed reducer, it is necessary to lubricate and maintain the elevator traction machine speed reducer through a lubrication system to ensure the normal use of the elevator traction machine speed reducer.

[0003] The "a special anti-breaking-strand baffle for an elevator asynchronous main engine" described in the patent application number "CN202420272415.3" includes an asynchronous main engine. The utility model solves the problem that the existing asynchronous main engine lacks a device for preventing the traction steel wire rope from slipping out of the groove.

[0004] During the use of the above-mentioned equipment, only the internal gears can be lubricated, and the position where the traction wheel contacts the steel wire rope cannot be lubricated. In addition, modern elevator traction machines usually adopt a gearless design. Therefore, this equipment cannot reduce the increase in the friction coefficient between the steel wire rope and the traction wheel caused by excessive elevator operation times, the lubricating oil being exhausted and not added in time, resulting in wear on the surfaces of the steel wire rope and the traction wheel, increasing their surface roughness, further intensifying the friction between the steel wire rope and the traction wheel, ultimately leading to a decrease in elevator operation efficiency, and at the same time, the energy consumption and noise level will also increase accordingly.

[0005] Therefore, the utility model provides a traction device for an elevator machine room to solve the above problems. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a traction device for an elevator machine room, which solves the problem that the above-mentioned equipment cannot reduce the increase in friction between the traction wheel and the steel wire rope caused by excessive elevator operation times. This increase in friction will lead to a decrease in elevator operation efficiency, and at the same time, the energy consumption and noise level will also increase accordingly.

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions: A traction device for an elevator machine room includes a device base and a traction machine detachably installed on the device base. A traction wheel for traction of the elevator through a steel wire rope is rotatably connected to the front end of the traction machine. A lubrication assembly is arranged on the traction wheel, and the lubrication assembly is fixedly connected to the side of the traction machine to prevent dust and other impurities from entering the traction wheel.

[0008] The lubrication assembly includes a protective housing and a wire groove formed inside the protective housing, and the wire groove is matched with the wire rope to prevent the wire rope from slipping out of the groove on the traction sheave. A plurality of round holes are formed in the inner wall of the wire groove, and the round holes are arranged at equal intervals. Steel balls are placed in the plurality of round holes, and the diameter of the steel balls is larger than the diameter of the round holes so that the steel balls will not slip out of the round holes. An oil outlet groove is formed in the steel balls to ensure that the lubricating oil can drip onto the wire rope. An oil storage tank for filling the lubricating oil is formed inside the protective housing, and the oil storage tank is communicated with the round holes on the wire groove.

[0009] Preferably, the lubrication assembly further includes an oil inlet for injecting the lubricating oil, and a regulating valve for adjusting the flow rate of the lubricating oil is detachably connected to the oil inlet. A lubricating tank is detachably connected to the regulating valve so that the lubricating oil can be conveniently replenished.

[0010] Preferably, a drainage plate is provided at the end of the protective housing, brakes for deceleration are provided on both sides of the traction machine, and a large gap is left between the protective housing and the brakes to prevent the lubricating oil from splashing onto the brakes on both sides of the traction machine.

[0011] Preferably, a limiting ring for preventing the steel balls from entering the oil storage tank is further provided inside the round holes, and a spring for resetting the steel balls is provided between the limiting ring and the steel balls so that the steel balls can be automatically reset when the wire rope is driven.

[0012] Preferably, a rubber ring is fixedly connected to the inner side wall of the oil inlet to prevent the lubricating oil from overflowing, and the steel balls have a smooth surface so that no additional friction is added during the transmission between the traction sheave and the wire rope.

[0013] Preferably, the regulating valve and the lubricating tank are detachably connected by a thread and a thread groove, and a rubber ring for sealing is provided at the connection between the regulating valve and the lubricating tank.

[0014] The present utility model provides a traction device for an elevator machine room. Compared with the prior art, the following beneficial effects are achieved:

[0015] (1). In the traction device for the elevator machine room, the traction sheave drives the wire rope to rotate, and the wire rope contacts the steel balls inside the wire groove, causing the steel balls to move towards the inside of the oil storage tank of the wire groove. The lubricating oil in the oil storage tank seeps out from the inside of the wire groove and is applied to the surface of the wire rope. At the same time, under the action of the traction sheave, the lubricating oil can penetrate into the contact position between the traction sheave and the wire rope, thereby avoiding the surface wear of the wire rope and the traction sheave due to the increase in the number of elevator operations, the increase in their surface roughness, the increase in the friction force between the traction sheave and the wire rope, and the resulting reduction in the operating efficiency of the elevator, as well as the simultaneous increase in energy consumption and noise level.

[0016] (2) The traction device of this elevator machine room fixes the lubricating tank to the regulating valve, and adjusts the speed of the lubricating oil flowing into the interior of the protective housing through the knob on the regulating valve, so that the lubricating oil can be replenished more conveniently. Moreover, the rubber ring between the oil inlet, the regulating valve and the lubricating tank can prevent the overflow of the lubricating oil, avoid waste of the lubricating oil, and prevent the lubricating oil from splashing onto the brake of the equipment and affecting the operation of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1:

[0024] Please refer to Figures 1 to 4 , a traction device of an elevator machine room, including an equipment base 2 and a traction machine 1 detachably installed on the equipment base 2. A traction wheel 4 for traction of the elevator through a steel wire rope 5 is rotatably connected to the front end of the traction machine 1. A lubrication assembly 6 is provided on the traction wheel 4, and the lubrication assembly 6 is fixedly connected to the side of the traction machine 1 so that dust and other impurities will not enter the traction wheel 4;

[0025] The lubricating assembly 6 includes a protective housing 61 and a wire groove 62 formed inside the protective housing 61. The wire groove 62 is matched with the wire rope 5 to prevent the wire rope 5 from slipping out of the groove on the traction sheave 4. A plurality of round holes are formed in the inner wall of the wire groove 62, and the round holes are arranged at equal intervals. Steel balls 64 are placed in each of the plurality of round holes, and the diameter of the steel balls 64 is larger than the diameter of the round holes, so that the steel balls 64 will not slip out of the round holes. Oil discharge grooves are formed in the steel balls 64 to ensure that the lubricating oil can drip onto the wire rope 5. An oil storage tank 63 for filling the lubricating oil is formed inside the protective housing 61, and the oil storage tank 63 is communicated with the round holes on the wire groove 62. A drainage plate is provided at the end of the protective housing 61. Brakes 3 for deceleration are provided on both sides of the traction machine 1, and a large gap is left between the protective housing 61 and the brakes 3 to prevent the lubricating oil from splashing onto the brakes 3 on both sides of the traction machine 1. A limiting ring 66 for preventing the steel balls 64 from entering the oil storage tank 63 is further provided inside the round holes, and a spring 65 for resetting the steel balls 64 is provided between the limiting ring 66 and the steel balls 64, so that the steel balls 64 can automatically reset when the wire rope 5 is driving. At the same time, when the elevator is running, the traction sheave 4 will drive the wire rope 5 to rotate, and the contact between the wire rope 5 and the steel balls 64 inside the wire groove 62 causes the steel balls 64 to move towards the inside of the oil storage tank 63 of the wire groove 62, so that the lubricating oil in the oil storage tank 63 seeps out from inside the wire groove 62 and is applied to the surface of the wire rope 5. At the same time, under the action of the traction sheave 4, the lubricating oil can penetrate into the contact position between the traction sheave 4 and the wire rope 5, thereby avoiding the increase in the friction force between the traction sheave 4 and the wire rope 5 caused by the increase in the number of elevator operations, resulting in a reduction in the operating efficiency of the elevator, and the synchronous increase in energy consumption and noise level. And the spring 65 between the steel balls 64 and the limiting ring 66 can keep the steel balls 64 restricted between the wire rope 5 and the wire groove 62, so as to prevent the steel balls 64 from slipping out inside the wire groove 62. Through the above equipment, the maintenance frequency of the elevator can be reduced, and the lubricating oil can be applied to the equipment without disassembling the equipment, which reduces the work burden.

[0026] Embodiment 2:

[0027] Please refer to Figures 1 to 4, this embodiment provides a technical solution based on Embodiment 1: The lubrication assembly 6 further includes an oil inlet 67 for instilling lubricating oil, and a regulating valve 7 for adjusting the flow rate of the lubricating oil is detachably connected to the oil inlet 67. A lubricating oil tank 8 is detachably connected to the regulating valve 7 to enable convenient replenishment of the lubricating oil. A rubber ring is fixedly connected to the inner side wall of the oil inlet 67 to prevent the lubricating oil from overflowing. Moreover, the steel ball 64 has a smooth surface so that no additional friction will be generated during the transmission between the traction wheel 4 and the steel wire rope 5. The regulating valve 7 and the lubricating oil tank 8 are detachably connected by a thread and a thread groove, and a rubber ring for sealing is provided at the connection between the regulating valve 7 and the lubricating oil tank 8 to fixedly connect the lubricating oil tank 8 to the regulating valve 7. The speed of the lubricating oil flowing into the protective housing 61 is adjusted through the knob on the regulating valve 7, so that the lubricating oil can be replenished more conveniently. Moreover, the rubber rings between the oil inlet 67, the regulating valve 7, and the lubricating oil tank 8 can prevent the overflow of the lubricating oil, avoid waste of the lubricating oil, and prevent the lubricating oil from splashing onto the brake 3 of the equipment and affecting the operation of the equipment.

[0028] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] Working principle: During operation, the lubricating oil tank 8 is fixedly connected to the regulating valve 7, and the speed of the lubricating oil flowing into the protective housing 61 is adjusted through the knob on the regulating valve 7 (the regulating valve 7 is an existing technology used to adjust the flow rate of the lubricating oil, which is common knowledge in this technical field and will not be elaborated here). In this way, the lubricating oil can be replenished more conveniently. Moreover, the rubber rings between the oil inlet 67 and the regulating valve 7, and between the regulating valve 7 and the lubricating oil tank 8 can prevent the overflow of the lubricating oil, avoid waste of the lubricating oil, and prevent the lubricating oil from splashing onto the brake 3 of the equipment and affecting the operation of the equipment. At the same time, when the elevator is running, the traction wheel 4 drives the steel wire rope 5 to rotate, and the steel wire rope 5 contacts the steel balls 64 inside the steel wire groove 62, causing the steel balls 64 to move into the oil storage groove 63 of the steel wire groove 62. Under the action of the oil outlet grooves on the steel balls 64, the lubricating oil in the oil storage groove 63 seeps out from inside the steel wire groove 62 and is applied to the surface of the steel wire rope 5. At the same time, under the action of the traction wheel 4, the lubricating oil can penetrate into the contact position between the traction wheel 4 and the steel wire rope 5, thereby preventing the surface of the steel wire rope 5 and the traction wheel 4 from being worn due to the increase in the number of elevator operations, resulting in an increase in their surface roughness, an increase in the friction force between the traction wheel 4 and the steel wire rope 5, a decrease in the operating efficiency of the elevator, and a simultaneous increase in energy consumption and noise level. Moreover, the spring 65 between the steel ball 64 and the limiting ring 66 can keep the steel ball 64 restricted between the steel wire rope 5 and the steel wire groove 62 to prevent the steel ball 64 from coming out of the steel wire groove 62. Through the above equipment, the maintenance frequency of the elevator can be reduced, and lubricating oil can be applied to the equipment without disassembling the equipment, reducing the workload.
