[0031] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0032] like Figures 1 to 8 As shown, the present invention provides an elevator maintenance transmission device based on the Internet, comprising: Shell 1; A placement plate 2 is fixedly mounted on the inner wall of the housing 1 and is used to place power machine parts; The power mechanism 3 is fixedly mounted on the top of the placement plate 2 and is used to provide power for the operation of the car; The buffer mechanism 4 is arranged on both sides and the bottom of the inner wall of the shell 1 to protect the operation of the car; The auxiliary mechanism 5 is arranged at the bottom of the inner wall of the shell 1 and is used for assisting the operation of the power mechanism 3 .

[0033] like Figures 1 to 8 As shown, the power mechanism 3 includes a first motor 301, the output end of the first motor 301 is fixedly connected to a worm 302, the surface of the worm 302 is meshed with a worm wheel 303, the inside of the worm wheel 303 is fixedly connected to a cross bar 304, both sides of the cross bar 304 are movably connected to vertical plates 305 through bearing seats, the bottom of the vertical plates 305 is fixedly connected to the top of the placement plate 2, both sides of the surface of the cross bar 304 are movably connected to output rods 307 through bevel gears 306, both sides of the surface of the output rod 307 are fixedly connected to guide wheels 308, the surface of the guide wheel 308 is movably connected to a pull rope 309, the pull rope 309 is located at the bottom of the left side of the first motor 301 and is fixedly connected to an elevator car 310, the pull rope 309 is located at the bottom of the right side of the first motor 301 and is fixedly connected to a box 311, a counterweight block 312 is placed inside the box 311, and the bottom of the pull rope 309 passes through the bottom of the placement plate 2.

[0034] In the embodiment of the present invention (working principle), when in use, the user activates the power mechanism 3: When the elevator receives the operation command, the first motor 301 starts to work. A worm 302 is fixedly connected to the output end of the motor, so the rotation of the motor drives the worm 302 to rotate.

[0035] Transmission of worm 302 and worm wheel 303: The surface of the worm 302 meshes with the worm wheel 303, so the rotation of the worm 302 drives the worm wheel 303 to rotate. A crossbar 304 is fixedly connected inside the worm wheel 303, so that the rotation of the worm wheel 303 is converted into the rotation of the crossbar 304.

[0036] Connection between the crossbar 304, the vertical plate 305 and the placement plate 2: The crossbar 304 is movably connected to the vertical plate 305 through the bearing seat, and the bottom of the vertical plate 305 is fixedly connected to the placement plate 2. This design allows the vertical plate 305 and the placement plate 2 to remain relatively stable when the crossbar 304 rotates, and does not rotate with the crossbar 304.

[0037] Transmission of the bevel gear 306 and the output rod 307: Both sides of the surface of the crossbar 304 are movably connected with output rods 307 through bevel gears 306. When the crossbar 304 rotates, the meshing of the bevel gears 306 drives the output rods 307 to rotate.

[0038] Transmission of guide wheel 308 and pull rope 309: A guide wheel 308 is fixedly connected to the surface of the output rod 307, and a pull rope 309 is wound around the guide wheel 308. As the output rod 307 rotates, the guide wheel 308 drives the pull rope 309 to move.

[0039] The bottom of the pull rope 309 passes through the bottom of the placement plate 2 and is respectively connected to the elevator car 310 (located on the left side of the first motor 301 ) and the box 311 . A counterweight block 312 is placed inside the box 311 , which is located on the right side of the first motor 301 .

[0040] Balancing motion of elevator car 310 and counterweight 312: When the first motor 301 rotates and drives the pull rope 309 to move through a series of transmission mechanisms, the elevator car 310 will rise or fall accordingly. At the same time, since the other end of the pull rope 309 is connected to the counterweight 312 in the box 311, the counterweight 312 will also rise or fall accordingly to keep the balance of the entire system.

[0041] The presence of the counterweight block 312 can effectively reduce the burden on the motor and improve the stability and efficiency of the elevator operation.

[0042] like Figures 1 to 8 As shown, the buffer mechanism 4 includes a buffer rope 401, which is fixedly installed at the four corners of the top of the elevator car 310. The top of the buffer rope 401 passes through the top of the placement plate 2 and is fixedly connected to a damping box 402. Both sides of the inner wall of the shell 1 are fixedly connected to a winding box 403. The interior of the winding box 403 is movably connected to a hook lock 404 through a damper. Motors 405 are fixedly installed on both sides of the elevator car 310. The output end of the motor 405 is fixedly connected to an adjusting plate 406. The outer side of the adjusting plate 406 is movably connected to both sides of the elevator car 310 through an axle pin. The top of the inner side of the section plate 406 is fixedly connected with a hanging rod 407, which is used in conjunction with the hook lock 404. The elevator car 310 is provided with a buffer plate 408. The four corners of the bottom of the buffer plate 408 are fixedly connected with a limiting rod 409. The surface of the limiting rod 409 is slidably connected with a limiting tube 410. The bottom of the limiting tube 410 is fixedly connected to the bottom of the inner wall of the outer shell 1. A buffer air cushion 411 is provided inside the limiting tube 410. A vertical groove 12 is opened on the surface of the inner wall of the limiting tube 410. A vertical block 413 used in conjunction with the vertical groove 12 is fixedly connected to the surface of the limiting rod 409.

[0043] In the embodiment of the present invention, the buffer rope 401 and the damping box 402: when the elevator car 310 encounters a sudden stop or deceleration during operation, the elevator car 310 will continue to move forward due to inertia. At this time, the buffer ropes 401 installed at the four corners of the top of the elevator car 310 will begin to stretch to absorb part of the impact energy. The top of the buffer rope 401 passes through the placement plate 2 and is fixedly connected to the damping box 402. The damping box 402 is filled with damping material. When the buffer rope 401 is stretched, the damping material will provide additional resistance to further slow down the impact speed of the elevator car 310 and protect the safety of passengers and equipment. Working principle of hook lock 404 and reel box 403 Winding box 403, damper and hook lock 404: Winding boxes 403 are fixed on both sides of the inner wall of the shell 1. The inside of the winding box 403 is movably connected to the hook lock 404 through a damper. The damper can provide a certain resistance to prevent the hook lock 404 from being suddenly released under uncontrolled conditions. Motors 405 are installed on both sides of the elevator car 310. The motor 405 drives the adjustment plate 406 to rotate. The adjustment plate 406 is movably connected to the elevator car 310 through an axle pin so that it can rotate flexibly. When the elevator car 310 needs to stop, the motor 405 is started to drive the adjustment plate 406 to rotate to an appropriate position, so that the hanging rod 407 cooperates with the hook lock 404 in the winding box 403. The hook lock 404 is slowly released under the action of the damper and locked with the hanging rod 407, thereby fixing the position of the elevator car 310. This design improves the stability and safety of the elevator stop and prevents the elevator car 310 from slipping due to sudden power outages or failures. Working principle of buffer plate 408 and limit tube 410 Buffer plate 408, limit rod 409 and limit tube 410: A buffer plate 408 is arranged inside the elevator car 310 to provide additional protection when the elevator car 310 is impacted. The four corners at the bottom of the buffer plate 408 are fixedly connected to the limit rod 409. The limit rod 409 slides in the limit tube 410. The bottom of the limit tube 410 is fixedly connected to the inner wall of the outer shell 1, providing stable guidance and support for the limit rod 409. A buffer air cushion 411 is arranged inside the limit tube 410. When the elevator car 310 is impacted, the limit rod 409 will compress the buffer air cushion 411, thereby absorbing part of the impact energy. The elasticity of the buffer air cushion 411 can slow down the impact speed and protect passengers and equipment from damage.

[0044] like Figures 1 to 8As shown, the auxiliary mechanism 5 includes a second motor 51, which is fixedly mounted on the bottom of the inner wall of the outer shell 1, and the output end of the second motor 51 is fixedly connected to a turntable 52, and the surface of the turntable 52 is movably connected to an auxiliary rope 53, and the top of the auxiliary rope 53 close to the elevator car 310 is fixedly connected to the bottom of the frame 311, and the top of the auxiliary rope 53 away from the elevator car 310 is fixedly connected to the top of the elevator car 310 through a fixed pulley 54, and the fixed pulley 54 is fixedly mounted on the bottom of the placement plate 2, and the fixed pulley 54 is used in conjunction with the auxiliary rope 53.

[0045] In the embodiment of the present invention, by starting the second motor 51, the turntable 52 is driven to rotate by the rotation of the second motor 51, thereby driving the auxiliary rope 53 to rotate. When the elevator car 310 rises, the frame 311 descends. By rotating the turntable 52 counterclockwise, the auxiliary rope 53 at the bottom of the frame 311 pulls the frame 311 to move toward the bottom. When the elevator car 310 moves to the bottom, the frame 311 moves to the top, thereby rotating the turntable 52 in the opposite direction, so that the auxiliary rope 53 pulls the frame 311 to the top, which is convenient for users to use.

[0046] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
