Description

Technical Field

[0001] The invention relates to the technical field of an environmentally friendly self-cleaning hydraulic passenger elevator without a machine room, and in particular to an environmentally friendly self-cleaning hydraulic passenger elevator without a machine room. Background Art

[0002] A hydraulic elevator is an elevator that uses a hydraulic power source to pressurize oil into the cylinder to make the plunger move in a straight line, thereby moving the car directly or indirectly through a wire rope. A hydraulic elevator is a product that integrates mechanics, electricity, electronics, and hydraulics, and is composed of the following relatively independent but interconnected and coordinated systems: pump station system, hydraulic system, guide system, car, door system, electrical control system, safety protection system, etc.

[0003] The hydraulic cylinder in a hydraulic elevator is the most important component for driving the car up and down, and plays an important role in use. By pressing hydraulic oil into the hydraulic cylinder, the plunger in the hydraulic cylinder is pushed up; and when the plunger rises, oil stains will remain on the outer wall of the plunger, and the plunger will come into contact with the air after rising, and the dust or floating particles in the air will adhere to the outer wall of the plunger because of the oil stains. When the plunger descends and retracts into the hydraulic cylinder, the dust particles on the outer wall of the plunger will cause wear and scratches on the inner wall of the hydraulic cylinder, causing the sealing between the plunger and the hydraulic cylinder to weaken, greatly reducing the service life of the hydraulic cylinder, and in severe cases causing hydraulic oil leakage, causing the car to slide down rapidly, posing a safety hazard. Summary of the invention

[0008] In order to improve the cleaning effect on the push rod, further, the second gear is rotatably connected to the top of the hydraulic cylinder.

[0011] In order to facilitate the driving of the piston plate in the piston cylinder to slide back and forth, further, the fixed plate is rotatably connected with a connecting shaft, one end of the connecting shaft is fixedly connected with an eccentric wheel, an annular connecting groove is opened on the circumference of the outer diameter of the eccentric wheel, and the end of the sliding rod away from the piston cylinder is slidably connected in the annular connecting groove.

[0012] In order to facilitate driving the impeller to rotate continuously, further, the piston cylinder is symmetrically arranged on both sides of the eccentric wheel.

[0017] S2: After the gas in the piston cylinder enters the installation box, the impeller rotates, and drives the third gear to rotate. The third gear meshes with the second gear to rotate, and drives the wiping cloth to wipe and clean the ejector rod;

[0018] S3: The gas entering the installation box is discharged into the air passage of the connecting ring through the second connecting pipe, and is blown onto the ejector rod from the blowing hole.

[0019] Compared with the prior art, the present invention provides an environmentally friendly self-cleaning machine room-less hydraulic passenger elevator, which has the following beneficial effects:

[0020] 1. For the environmentally friendly self-cleaning machine room-less hydraulic passenger elevator, when the push rod rises, the crossbeam drives the rack to rise, and the rising rack drives the first gear to rotate by meshing with the first gear, and the first gear then drives the eccentric wheel to rotate through the connecting shaft. When the eccentric wheel rotates, it pulls the piston plate in the piston cylinder back and forth through the annular connecting groove to slide, and when sliding, air is introduced into the piston cylinder through the air inlet pipe, and when the piston plate is pushed by the eccentric wheel, the gas is squeezed out through the air outlet pipe, and the gas enters the first connecting pipe through the air outlet pipe, and enters the installation box, blowing the impeller to rotate, and when the impeller rotates, it drives the second gear to rotate at the top of the hydraulic cylinder through the meshing of the third gear, and the rotation of the second gear drives the wiping cloth to wipe the outer wall of the push rod, wipe the dust or foreign matter adhering to the outer wall of the push rod, and further improve the wiping effect through rotation.

[0021] 2. For the environmentally friendly self-cleaning machine room-less hydraulic passenger elevator, the gas entering the installation box enters the air duct of the connecting ring through the second connecting pipe, and is discharged from the blowing hole and blown onto the top rod. It can be pre-cleaned before wiping with the wiping cloth to blow away the dust that can be blown off the top rod, further improving the effect of wiping the top rod with the wiping cloth.

[0022] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the push rod is lifted up and down, the rack is driven to lift up and down synchronously. When the rack is lifted up and down, the meshing drives the first gear to rotate, and drives the piston cylinder to intake air into the installation box through the eccentric wheel. The second gear is driven to rotate on the push rod by driving the impeller to rotate, and the push rod is wiped during rotation to prevent dust or particles from entering the hydraulic cylinder, thereby increasing the service life of the hydraulic cylinder. When cleaning the outer wall of the push rod, the device does not need to use other electrical equipment to effectively clean the outer wall of the push rod. BRIEF DESCRIPTION OF THE DRAWINGS
