Description

Technical Field

[0001] This invention belongs to the field of elevator technology, and specifically relates to a mobile elevator. Background Technology

[0002] A mobile elevator is an elevator installed inside a mobile home that can move with the mobile home. Mobile homes, as a new form of housing, are gradually gaining popularity due to their high flexibility and ability to be easily relocated as needed.

[0003] As shown in Chinese patent document CN119683438B, a mobile elevator is disclosed, including a pair of lower car guide rails, a pair of upper car guide rails, a pair of lower counterweight guide rails, a pair of upper counterweight guide rails, a car, a counterweight, traction ropes, a traction machine, a rope end fixing assembly, and a rope end winding machine. The lower car guide rails and lower counterweight guide rails are installed in the bottom room, and the upper car guide rails and upper counterweight guide rails are installed in the top room. The rope end winding machine is installed on the top plate. When the bottom room and the top room are separated, the car and counterweight can be lifted into the top room first by the traction machine and the rope end winding machine. The mobile elevator only needs to be separated at the docking points of the lower car guide rails and the upper car guide rails, as well as the docking points of the lower counterweight guide rails and the upper counterweight guide rails. Other components remain in their original installation positions and move with the bottom room and the top room, greatly improving the ease of operation for changing the position of the mobile elevator. It is compatible with the installation and use conditions of mobile houses and meets the requirements for flexible movement.

[0004] While existing mobile elevators can meet the needs of flexible movement, their traction elevator structure makes the overall structure more complex and heavier, increasing the difficulty of hoisting and moving them. Therefore, it is necessary to further optimize the structure of mobile elevators in accordance with the usage scenarios to make them meet the application requirements of mobile elevators.

The rope end fixing plate is fitted into the recessed position, and the steel wire rope is led out from the position where the recessed position communicates with the winding grooves. The end face sealing plate is fixedly connected to the end face of the pulley body, thus fixing the rope end fixing plate within the recessed position. The recessed position is formed by recessing inward from the end face of the pulley body, and includes... The wheel body has a semi-annular groove and an open groove. A central shaft hole is provided at the center of the wheel body for connection with the output shaft of the reducer. The central axis of the semi-annular groove coincides with the central axis of the central shaft hole. The semi-annular groove is located between the central shaft hole and the winding groove. The open groove radially connects the semi-annular groove to the outside of the wheel body and is also connected to the winding groove.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] like Figures 1 to 18As shown, this embodiment discloses a mobile elevator, including a pair of lower car guide rails 3, a pair of upper car guide rails 4, a main frame 5, a drive unit 6, a backpack frame 7, a car 8, and a car locking mechanism 9. The mobile house includes a bottom room 1 and a top room 2. The top room 2 is detachably installed on the bottom room 1. The pair of lower car guide rails 3 and the pair of upper car guide rails 4 are respectively fixedly installed in the bottom room 1 and the top room 2. The lower car guide rails 3 and the upper car guide rails 4 are connected by a connecting plate 10. The lower car guide rails 3 and the upper car guide rails 4 are joined vertically to form car guide rails for limiting the vertical movement of the car 8. The main frame 5 is fixedly installed on the top of the pair of upper car guide rails 4. The drive unit 6 is fixedly installed on the main frame 5. The backpack frame 7 slides with the car guide rails. The car 8 is fixedly installed on the backpack frame 7. The drive unit 6 is connected to the backpack frame 7 through a steel wire rope to drive the backpack frame 7. The moving car 8 moves up and down, and the car locking mechanism 9 is fixed inside the top floor room 2 and located between a pair of upper car guide rails 4; the drive host 6 includes a drive motor 61, a reducer 62, a drive rope pulley 63 and a brake 64. The reducer 62 is connected to the rotating shaft of the drive motor 61, and the drive rope pulley 63 is connected to the output shaft 6231 of the reducer 62. The output shaft 6231 of the reducer 62 extends to the brake 64 and is connected to the brake 64; when the drive motor 61 is working, it drives the drive rope pulley 63 to rotate through the reducer 62. The drive rope pulley 63 drives the wire rope to perform winding and unwinding work on the outer circumference of the drive rope pulley 63, thereby driving the backpack frame 7 and the car 8 to move up and down. The brake 64 achieves the effect of elevator braking by limiting the rotation speed of the output shaft 6231 of the reducer 62; the bottom of the backpack frame 7 is provided with an anti-falling bracket 71, and the car locking mechanism 9 is adapted to the anti-falling bracket 71. When the mobile elevator needs to be moved, the backpack frame 7 and the car 8 are first moved upwards to the upper floor. The brake 64 is activated, keeping the output shaft 6231 of the reducer 62 in a braking state, thus keeping the drive pulley 63 stationary. At the same time, the car locking mechanism 9 is activated, extending into the anti-fall latch 71 to cooperate with the anti-fall latch 71 to prevent the car 8 from falling due to brake failure, thus improving the safety of elevator transfer and the safety of elevator assembly and disassembly personnel. Then, the staff enters the elevator shaft and removes the connecting plate 10, allowing the lower car guide rail 3 and the upper car guide rail 4 to be separated. The bottom floor 1 and the top floor 2 are then hoisted and moved to the designated positions and re-fixed. Other elevator components do not need to be disassembled. After the bottom floor 1 and the top floor 2 are fixed in their new positions, the lower car guide rail 3 and the upper car guide rail 4 are fixed again using the connecting plate 10 to restore the elevator to normal use and meet the requirements for flexible movement. Furthermore, the overall structure of the mobile elevator in this embodiment is simplified, and it does not have a counterweight, which reduces the overall weight of the elevator and makes it easier to move and transport. This embodiment uses multiple steel wire ropes to distribute the weight carried by the car 8, thereby ensuring the elevator's load-bearing capacity.Meanwhile, for mobile elevators, the space of the car 8 is relatively small, and the number of people carried at one time is less than 3. Therefore, the operating load is not large. Generally, a maximum load of 250kg is sufficient to meet the usage requirements. Thus, the load requirements of the drive motor 61 are not high. Generally, a drive motor 61 with a power of 2500W can meet the operating requirements of the elevator. The low requirements for the drive motor 61 reduce the technical conditions for the implementation of mobile elevators and avoid the problem of excessive load on the drive motor and long-term overload operation leading to increased failure rate. This ensures that the mobile elevator meets the usage requirements for safe operation.

[0038] Specifically, the backpack frame 7 includes a pair of backpack uprights 72, a pair of backpack support beams 73, a backpack connecting beam 74, and a rope end fixing component 75. The pair of backpack uprights 72 are slidably connected to the car guide rails via guide shoes. The pair of backpack support beams 73 are fixed to the bottom of the pair of backpack uprights 72. The two ends of the backpack connecting beam 74 are fixedly connected to the pair of backpack support beams 73. The rope end fixing component 75 is fixed to the rear side of the backpack connecting beam 74, and the end of the steel wire rope is fixedly connected to the rope end fixing component 75. Each of the two backpack support beams 73 is equipped with a fall arrestor 71, which has openings on opposite sides and the rear side of the two backpack support beams 73. The car locking mechanism 9 includes a fixed bracket 91, an electric rotator 92, a pair of connecting rods 93 and a pair of locking arms 94. The fixed bracket 91 is fixed inside the top floor body 2. The electric rotator 92 is fixed on the fixed bracket 91. The electric rotator 92 is equipped with a rotating disk 95. The pair of locking arms 94 are rotatably connected to the rotating disk 95 by a pair of connecting rods 93. One end of the connecting rod 93 is rotatably connected to the rotating disk 95, and the other end of the connecting rod 93 is rotatably connected to one end of the locking arm 94. The other end of the locking arm 94 is a free end. The locking arm 94 is a corner structure, and the corner of the locking arm 94 is an obtuse angle. The corner of the locking arm 94 is rotatably connected to the fixed bracket 91. When the mobile elevator needs to be disassembled, the electric rotator 92 is controlled to rotate the rotating disk 95, causing a pair of locking arms 94 to extend. A pair of connecting rods 93 connected to the rotating disk 95 push the locking arms 94 on both sides to extend into the anti-fall locking positions 71. Through the cooperation of the locking arms 94 with the backpack support beams 73, the backpack frame 7 and the car 8 are protected from falling. When the brake 64 fails to provide effective braking to the backpack frame 7 and the car 8, the locking arms 94 can support and lock the backpack frame 7, preventing them from falling. Furthermore, during the mobile elevator's movement, the power needs to be disconnected. In this embodiment, the locking arms 94 can remain extended even when the power is disconnected, cooperating with the anti-fall locking positions 71 of the backpack frame 7 to effectively support and lock the backpack frame 7, avoiding the problem of power failure. After the mobile elevator is reinstalled, the electric rotator 92 is controlled to rotate in the opposite direction, so that the pair of locking arms 94 are retracted and the pair of locking arms 94 leave the fall arrestor 71 and exit the space where the backpack frame 7 moves up and down, and the mobile elevator resumes normal use.

[0039] Furthermore, to improve the support capacity of the locking arm 94 and enable it to stably prevent the backpack frame 7 and the car 8 from falling, the fixed bracket 91 includes a bracket body 911 and a pair of mounting seats 912. The bracket body 911 is fixed to the inner wall of the top floor room 2, the pair of mounting seats 912 are fixed to the bracket body 911, and the pair of locking arms 94 are rotatably connected to the pair of mounting seats 912 respectively. The connecting rod 93 is connected to the bottom surface of the locking arm 94. The mounting seat 912 is provided with a raised step 9121 for supporting the locking arm 94. The corner of the locking arm 94 is connected to the raised step 9121 through a connector, so that the locking arm 94 is rotatably connected to the mounting seat 912. The rear side of the raised step 9121 is provided with a first movable position 9122 and a second movable position 9123. The top of the second movable position 9123 is provided with a pressure plate 9124. When the locking arm 94 is in the retracted state, one end of the locking arm 94 connecting to the connecting rod 93 is located in the first movable position 9122; when the locking arm 94 is in the extended state, one end of the locking arm 94 connecting to the connecting rod 93 is located in the second movable position 9123, and the bottom surface of the pressure plate 9124 presses against the top surface of the locking arm 94. When the backpack frame 7 and the car 8 fall, downward pressure is applied to the free end of the locking arm 94. At this time, one end of the locking arm 94 connecting to the connecting rod 93 has a tendency to tilt upward. By setting the pressure plate 9124 on the second movable position 9123, downward pressure is applied to one end of the locking arm 94 connecting to the connecting rod 93, thereby preventing the locking arm 94 from tilting upward and damaging the connection. Preferably, the mounting base 912 includes a base body 9125 and an enclosure 9126. The enclosure 9126 has a "7"-shaped structure and includes a vertical plate 9127 and a pressure plate 9124. The vertical plate 9127 is fixed to the rear side of the base body 9125 corresponding to the second movable position 9123. One end of the pressure plate 9124 is connected to the top of the vertical plate 9127, and the other end of the pressure plate 9124 extends forward to cover the top of the second movable position 9123. In this embodiment, the locking arm 94 is connected through the mounting base 912, and the first movable position 9122 of the mounting base 912 is in an open state, which can effectively prevent the locking arm 94 from interfering with the mounting base 912 when it moves. By setting the pressure plate 9124 on the top of the second movable position 9123, the locking arm 94 can be provided with downward pressure when it is extended, thus providing connection protection for the locking arm 94. The raised step 9121 is also provided with a lifting limit member 9128 for limiting the locking arm 94 when it is in the extended state. The lifting limit member 9128 can be raised and lowered from the top surface of the raised step 9121.When the locking arm 94 is in the extended state, the lifting limit member 9128 protrudes from the top surface of the raised step 9121, limiting the locking arm 94 and preventing it from rotating under external force, thus ensuring the locking arm 94's locking effect on the backpack frame 7 and the car 8. When the locking arm 94 needs to rotate from the extended state to the retracted state, the lifting limit member 9128 sinks below the top surface of the raised step 9121, releasing its limiting effect on the locking arm 94. Specifically, the lifting limit member 9128 can be an electrical device capable of controlling extension and retraction, such as an electric telescopic rod. The mounting base 912 can also be an integral structure.

[0040] Specifically, the drive pulley 63 includes a pulley body 631, a rope end fixing plate 632, and an end face sealing plate 633. The outer circumference of the pulley body 631 is provided with several winding grooves 6311 for winding the wire rope. The pulley body 631 is provided with a recessed position 6312 that can accommodate the rope end fixing plate 632. The recessed position 6312 communicates with the winding grooves 6311. The rope end fixing plate 632 is provided with several sets of rope end holes 6321 for fixing and connecting the wire rope. Each set of rope end holes 6321 has two rope end holes 6321. When fixing the end of the wire rope, the end of the wire rope enters into one rope end hole 6321 and exits in the opposite direction through the other rope end hole 6321. The end of the wire rope is fixed and locked to the rope body of the wire rope by the rope end fixing ring, thereby binding the wire rope to the rope end fixing plate 632. After all the wire ropes are bound to the rope end fixing plate 632, the rope end fixing plate 632 is fitted into the recessed position 6312. The wire rope is led out from the position of the recessed position 6312 connecting to the winding groove 6311, and then fixedly connected to the end face of the wheel body 631 through the end face sealing plate 633, so that the rope end fixing plate 632 is fixed in the recessed position 6312. Specifically, the recessed position 6312 is formed by recessing inward from the end face of the wheel body 631. The recessed position 6312 includes a semi-annular groove 6313 and an open groove 6314. The center of the wheel body 631 is provided with a central shaft hole 6315 for connecting with the output shaft 6231 of the reducer 62. The central axis of the semi-annular groove 6313 coincides with the central axis of the central shaft hole 6315. The semi-annular groove 6313 is located between the central shaft hole 6315 and the take-up groove 6311. The open groove 6314 connects the semi-annular groove 6313 and the outside of the wheel body 631 radially, and the open groove 6314 is connected to the take-up groove 6311. The rope end fixing plate 632 includes a semi-annular plate 6322 adapted to the semi-annular groove 6313 and a boss 6323 adapted to the opening groove 6314. The boss 6323 is located on the outside of the semi-annular plate 6322, and its outer surface is flush with the bottom surface of the winding groove 6311, so that the wire rope can fully enter the winding groove 6311 during winding. The rope end hole 6321 is opened from the outer surface of the boss 6323 inward and passes through the inner side of the semi-annular plate 6322. By designing the semi-annular groove 6313 in the wheel body 631 and the semi-annular plate 6322 in the rope end fixing plate 632, the contact area between the rope end fixing plate 632 and the wheel body 631 can be increased to a large extent, ensuring the load-bearing capacity of the rope end fixing plate 632.

[0041] Specifically, the reducer 62 includes a front housing 621, a rear housing 622, an output shaft connector 623, an input shaft connector 624, and two planetary gears 625. The output shaft connector 623 includes, along the axial direction, an output shaft 6231, a first mounting section 6232, and a second mounting section 6233. The input shaft connector 624 is mounted on the second mounting section 6233. A sun gear 6241 is provided at the front end of the input shaft connector 624, extending into the first mounting section 6232. The two planetary gears 625 are mounted on the first mounting section 6232 and mesh with the outer sides of the planetary gears 625 respectively. The input shaft connector 624 has a bushing 6242 at its rear end for connecting the rotating shaft of the drive motor 61. The bushing 6242 extends from the rear end of the second mounting section 6233. The front housing 621 has an internal gear ring 6211. Two planetary gears 625 mesh with the internal gear ring 6211 respectively. The front housing 621 is connected to the rear housing 622. The input shaft extends from the front end of the front housing 621, and the bushing 6242 extends from the rear end of the rear housing 622. The central axes of the sun gear 6241 and the two planetary gears 625 are located on the same plane. The number of teeth of the sun gear 6241 is less than the number of teeth of the planetary gears 625. The rotating shaft of the drive unit 6 is connected to the bushing 6242. When the drive motor 61 rotates, it drives the input shaft connector 624 to rotate via the rotating shaft. The sun gear 6241 of the input shaft connector 624 drives the two planetary gears 625 to rotate. Under the meshing action of the two planetary gears 625 and the internal gear ring 6211, the two planetary gears 625 drive the output shaft connecting bracket 623 to revolve around the sun gear 6241, thereby causing the output shaft 6231 to rotate and output. In this embodiment, the reducer 62 transmits power through the meshing of the sun gear 6241 and the planetary gears 625, and the meshing of the planetary gears 625 and the internal gear ring 6211. This allows the planetary gears 625 to rotate on their own axes while revolving around the sun gear 6241, thus making the output of the reducer 62 smoother and more stable. Meanwhile, when one end of the output shaft 6231 serves as the power source, the planetary gear 625 needs to revolve and rotate to drive the sun gear 6241, resulting in significant resistance. Therefore, in this embodiment, the reducer 62 inputs a larger torque in the reverse direction, enabling a self-locking function. That is, when the drive motor 61 operates, moving the car 8 to the designated position, the drive pulley 63 can stop under the self-locking action of the reducer 62. The reducer 62 can only input in one direction, preventing the drive pulley 63 from rotating under the weight of the car 8 via the steel cable. Additionally, it should be noted that in this embodiment, the stopping action of the mobile elevator primarily relies on the brake 64 during operation. The self-locking function of the reducer 62 serves as an auxiliary stopping action, providing resistance to stabilize the elevator in a stopped state. The stopping and station holding during the elevator's up and down movement are achieved through the action of the brake 64.

[0042] Furthermore, a first support section 6234 is provided between the output shaft 6231 and the first mounting section 6232, and a second support section 6235 is provided between the first mounting section 6232 and the second mounting section 6233. Bearings are installed on the outer sides of the first support section 6234, the second support section 6235, and the input shaft connector 624. The output shaft connecting bracket 623 is rotatably connected to the front housing 621 through the bearings on the outer sides of the first support section 6234 and the second support section 6235. The input shaft connector 624 is rotatably connected to the rear housing 622 through the bearings on the outer side of the input shaft connector 624.

[0043] Specifically, the bottom surface of the upper car guide rail 4 is provided with an upwardly recessed positioning groove 41, and the top surface of the lower car guide rail 3 is provided with an upwardly protruding positioning strip 31. The positioning groove 41 is adapted to the positioning strip 31. The bottom of the upper car guide rail 4 is provided with an upper connecting hole 42, and the top of the lower car guide rail 3 is provided with a lower connecting hole 32. The connecting plate 10 includes a main plate surface 101 and two positioning plate surfaces 102. The two positioning plate surfaces 102 are arranged opposite to each other on both sides of the main plate surface 101. The main plate surface 101 is provided with an upper plate hole 103 corresponding to the upper connecting hole 42 and a lower plate hole 104 corresponding to the lower connecting hole 32. Both the upper car guide rail 4 and the lower car guide rail 3 are T-shaped guide rail structures, and both include a sliding guide rail strip 100 for sliding with the guide shoe and a fixing strip 200 for fixed installation. The sliding guide rail strip 100 is located in the middle of the fixing strip 200. When the upper car guide rail 4 and the lower car guide rail 3 are connected, the positioning strip 31 enters the positioning groove 41 for positioning, and the bottom and top of the upper car guide rail 4 are connected by the connecting plate 10. The connecting piece passes through the upper plate hole 103 and the upper connecting hole 42, and the lower plate hole 104 and the lower connecting hole 32 for fixation. When the connecting plate 10 is connected to the upper car guide rail 4 and the lower car guide rail 3, the main plate surface 101 of the connecting plate 10 is in contact with the outer side of the fixing strip 200 of the upper car guide rail 4 and the fixing strip 200 of the lower car guide rail 3, and the positioning plate surface 102 of the connecting plate 10 is in contact with the left and right sides of the fixing strip 200 of the upper car guide rail 4 and the lower car guide rail 3, thereby ensuring the stability and accuracy of the connection between the upper car guide rail 4 and the lower car guide rail 3.

[0044] In addition, in this embodiment, the elevator is installed on one side of the top floor room 2 and the bottom floor room 1. To prevent the center of gravity of the top floor room 2 and the bottom floor room 1 from becoming unbalanced during hoisting and movement, a photovoltaic panel 300 is installed on the top of the side of the top floor room 2 away from the elevator installation position, and a storage battery 400 is installed on the top of the side of the bottom floor room 1 where the elevator is installed. The storage battery 400 is electrically connected to the photovoltaic panel 300. After the photovoltaic panel 300 converts solar energy into electrical energy, it charges the storage battery 400. The storage battery 400 is electrically connected to the drive motor 61 to supply power to the elevator. By setting up a photovoltaic panel 300 on the top floor room 2 and a storage battery 400 on the bottom floor room 1 to balance the weight of the mobile elevator, the top floor room 2 and the bottom floor room 1 are more stable during hoisting and movement, reducing the instability of the hoisting and movement. In addition, by placing the battery 400 on the top of the ground floor 1, compared to placing it on the bottom of the ground floor 1, the battery 400 in this embodiment can be better protected, effectively preventing the ground floor 1 from being damaged by collision with stones on the ground when it is placed on the ground.
