Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to an intelligent and precise long-term lubrication device for escalators. Background Technology

[0002] An escalator is a continuous conveying machine with circulating steps used to transport passengers upwards and downwards at an incline. It mainly consists of a stairway including steps, a traction chain, a power drive unit, a handrail system, a metal structural frame, a truss, and safety devices. These parts are connected by a traction chain to form a circulating stairway. Driven by the power drive unit, the traction chain causes the steps to circulate along the guide rails, thus transporting people.

[0003] A search revealed Chinese Patent Publication No. CN109019285A, which discloses an escalator belonging to the field of elevator technology. This escalator solves the problem of inconvenient handrail cleaning in existing escalators. The escalator includes an escalator body, which includes a handrail. A support member is mounted on the escalator body's bracket, and two cleaning claws are symmetrically rotated on the support member. The inner ring of each cleaning claw has an arc that matches the outer arc surface of the handrail, and the arc has a cleaning part for wiping the outer ring of the handrail. When the two cleaning claws are rotated to a mutually fitted state, they can completely enclose the handrail in the cross-sectional direction. The two cleaning claws are connected by a pair of... The drive mechanism drives the rotation, and the two cleaning claws rotate synchronously in opposite directions. Compared with the existing technology, this escalator can automatically clean the escalator handrail with excellent cleaning effect. However, the long-term efficient and stable operation of the escalator depends on good lubrication conditions. The existing escalator lubrication system is maintained by manually adding lubricating oil periodically. However, when adding lubricating oil manually, it is impossible to accurately control the amount of lubricating oil added. As a result, the escalator will wear and be damaged due to insufficient lubrication or excessive addition of lubricating oil, thus reducing the service life of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an intelligent and precise long-term lubrication device for escalators, which aims to improve the problem in the prior art where insufficient or excessive manual addition of lubricating oil causes wear and damage to the equipment, thereby reducing the service life of the equipment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent and precise long-lasting lubrication device for escalators, comprising a body, a square plate fixedly connected to the top right side of the body, an oil storage tank fixedly connected to the top front side of the square plate, a flow regulating valve connected to the lower middle part of the outer wall of the oil storage tank, an oil delivery pipe fixedly connected to the inner wall of the flow regulating valve, a high-pressure pump fixedly connected to the middle of the top wall of the square plate, a controller fixedly connected to the top right side of the square plate, and a hollow inner sliding groove block fixedly connected to the top left side of the square plate. The block has a rack that slides inside. A long hollow plate is fixedly connected to the right side of the outer wall of the hollow inner sliding block. A threaded locking rod is threadedly connected to the middle of the outer wall of the long hollow plate. A fixed short column is rotatably connected to the rear side of the outer wall of the controller. A gear is fixedly connected to the left end of the outer wall of the fixed short column. The gear meshes with the rack. A nozzle is fixedly connected to the rear side of the outer wall of the rack. The other end of the oil pipe passes through the threaded locking rod and is fixedly connected to the nozzle. A cleaning mechanism is installed on the right side of the machine body. The cleaning mechanism is used to clean impurities and dust attached to the escalator chain.

[0006] The above technical solution works as follows: A humidity sensor first measures the ambient temperature and humidity, calculates the appropriate lubricating oil viscosity value, and transmits this value to the controller. Based on the viscosity value, the high-pressure pump extracts a fixed amount of lubricating oil from the storage tank and delivers it to the nozzle through the oil supply pipe. Then, the oil pressure sensor detects the oil pressure and transmits the information back to the controller. If abnormally low or high oil pressure is detected, the controller immediately adjusts the opening of the flow control valve to maintain smooth oil flow and stable oil supply. Finally, the lubricating oil is atomized into fine particles by the nozzle and evenly adheres to the surface of the escalator chain and other moving parts, forming a protective film that effectively isolates direct metal-to-metal contact and reduces wear. Rotating the fixed short column drives the left-end gear to mesh with the rack, allowing the nozzle height to be adjusted according to lubrication needs.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes a support plate mounted on the right side of the machine body. A motor is fixedly connected to the top of the support plate. A support frame is fixedly connected to the upper right side of the outer wall of the machine body. An inner sliding groove hollow long plate is fixedly connected to the bottom of the support frame. A connecting rod is fixedly connected to the output end of the motor. A double-section rotating rod is fixedly connected to the front end of the outer wall. A sliding block is fixedly connected to the front side of the outer wall of the double-section rotating rod. The sliding block is slidably connected to the inner sliding groove hollow long plate. A cleaning brush is fixedly connected to the front end of the sliding block.

[0009] The above technical solution works as follows: by turning on the motor at the top of the supporting short plate, the connecting short rod fixedly connected to the output end rotates, which in turn drives the double-section rotating rod at the front to rotate. When the double-section rotating rod rotates, it drives the sliding block on the front side to slide in the hollow long plate of the inner sliding groove at the bottom of the support frame. When the sliding block moves, it drives the cleaning brush at the front to clean the impurities and dirt attached to the escalator chain.

[0021] Through the above technical solution, the warning sign on the outer wall of the right handrail can remind passengers of precautions when riding the escalator to avoid danger.

[0022] As a further description of the above technical solution:

[0023] A second throttle is fixedly connected to the right end of the outer wall of the fixed short column, and a second protective sleeve is fixedly connected to the outer wall of the second throttle.

[0024] Through the above technical solution, the throttle two fixedly connected to the right end of the outer wall of the fixed short column can serve to fix the short column so that it can be rotated easily.

[0025] As a further description of the above technical solution:

[0026] A throttle is fixedly connected to the front end of the outer wall of the threaded block rod, and a protective sleeve is fixedly connected to the outer wall of the throttle.

[0027] The above technical solution allows the protective sleeve fixedly connected to the outer wall of the throttle to enhance the comfort of the operator's hands when turning the throttle.

[0029] 1. In this utility model, the ambient temperature and humidity are first measured by a humidity sensor. After calculating the appropriate viscosity value of the lubricating oil, the value is transmitted to the controller.

The oil is then atomized into fine particles and evenly adhered to the surface of the escalator chain and other moving parts to form a protective film. This avoids the problem of wear and damage to the equipment caused by insufficient or excessive manual addition of lubricating oil, which would reduce the service life of the equipment.

[0030] 2. In this utility model, by turning on the motor and rotating the connecting short rod fixedly connected to the output end, the connecting short rod will drive the double-section rotating rod at the front end to rotate. When the double-section rotating rod rotates, it will drive the sliding block on the front side to slide in the hollow long plate of the inner sliding groove at the bottom of the support frame. When the sliding block moves, it will drive the cleaning brush at the front end to clean the impurities and dirt attached to the escalator chain, thereby avoiding the problem of excessive dust and dirt on the chain affecting the overall lubrication effect.

[0045] Working principle: The humidity sensor 10 first measures the ambient temperature and humidity, calculates the appropriate lubricating oil viscosity value, and transmits it to the controller 8. Based on the viscosity value command, the high-pressure pump 18 extracts a certain amount of lubricating oil from the oil storage tank 6 and transmits it to the nozzle 27 through the oil delivery pipe 17. Then, the oil pressure sensor in the oil delivery pipe 17 detects the oil pressure information and transmits it back to the controller 8. When abnormally low or high oil pressure is detected, the controller 8 will immediately adjust the opening of the flow regulating valve 7 to maintain smooth oil flow and stable oil supply. Finally, the lubricating oil is atomized into fine particles by the nozzle 27 and then evenly adheres to the surface of the escalator chain and other moving parts, forming a protective film that effectively isolates direct metal-to-metal contact and reduces wear. By rotating the fixed short column 26, the left-end gear 28 meshes with the rack 25, and the height of the nozzle 27 can be adjusted according to the lubrication requirements for spraying. This avoids the problem of wear and damage to the equipment due to insufficient or excessive manual addition of lubricating oil, thus reducing the service life of the equipment.

[0046] By activating the motor 202 at the top of the supporting short plate 201, the connecting short rod 208, which is fixedly connected to the output end, rotates. As the connecting short rod 208 rotates, it drives the double-section rotating rod 203 at the front end to rotate. When the double-section rotating rod 203 rotates, it drives the sliding block 204 on the front side to slide within the hollow long plate 205 in the inner groove at the bottom of the support frame 206. As the sliding block 204 moves, it drives the cleaning brush 207 at the front end to clean the impurities and dirt attached to the escalator chain, thereby avoiding the problem of excessive dust and dirt on the chain affecting the overall lubrication effect.
