[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figures 1 to 10 As shown, this embodiment discloses a mobile elevator, comprising a pair of lower car guide rails 1, a pair of upper car guide rails 2, a pair of lower counterweight guide rails 3, a pair of upper counterweight guide rails 4, a car 5, a counterweight 6, a traction rope 7, a traction machine 8, a rope end fixing assembly 9 and a rope end winding machine 10, the pair of lower car guide rails 1 and the pair of lower counterweight guide rails 3 are all fixedly installed in the bottom floor housing 11, the pair of upper car guide rails 2 and the pair of upper counterweight guide rails 4 are all fixedly installed in the top floor housing 12; the lower car guide rails 1 and the upper car guide rails 2 are connected up and down to form a car guide rail for limiting the upward and downward movement of the car 5; the lower counterweight guide rails 3 and the upper counterweight guide rails 4 are connected up and down to form a counterweight guide rail for limiting the upward and downward movement of the counterweight 6;

[0030] A top plate 13 is fixedly provided on the top of the upper car guide rail 2 and the upper counterweight guide rail 4, and the traction machine 8, the rope end fixing assembly 9 and the rope end winder 10 are fixed on the top plate 13; one end of the traction rope 7 is fixed to the rope end fixing assembly 9, and the other end is fixed to the rope end winder 10 after passing through the counterweight 6, the traction machine 8 and the car 5 in sequence. The rope end winder 10 can wind up the traction rope 7 so that the car 5 and the counterweight 6 are both lifted and moved to the top floor room 12; a car locking device 14 is provided on the car 5, and the upper car guide rail 2 is provided with a car locking plate 15, and the car locking device 14 is adapted to the car locking plate 15. The mobile elevator of the present embodiment can meet the use conditions of mobile house disassembly and transportation. When the bottom house body 11 and the top house body 12 are disassembled, it is only necessary to control the traction machine 8 to make the car 5 rise to the top house body 12, and the car locking device 14 is actuated to cooperate with the car locking plate 15 to lock the car 5 in the top house body 12; then the traction machine 8 and the rope end winder 10 work synchronously, and the rope end winder 10 gradually winds up the traction rope 7 to make the counterweight 6 rise to the top house body 12; when the bottom house body 11 and the top house body 12 are disassembled, the mobile elevator only needs to be disassembled at the joints of the lower car guide rail 1 and the upper car guide rail 2, and the joints of the lower counterweight guide rail 3 and the upper counterweight guide rail 4. Each component of the mobile elevator can move with the bottom house 11 and the top house 12. After moving to a new location, it is only necessary to install and fix the bottom house 11 and the top house 12, so that the lower car guide rail 1 is connected with the upper car guide rail 2, and the lower counterweight guide rail 3 is connected with the upper counterweight guide rail 4; the traction machine 8 and the rope head winder 10 are controlled to work synchronously, and the rope head winder 10 gradually unwinds the traction rope 7, so that the counterweight 6 is lowered into the bottom house 11. After the traction rope 7 is unwound, the car locking device 14 is actuated, disengaged from the car locking plate 15, and the position lock of the car 5 is released, so that the mobile elevator can be restored to normal use without the need to disassemble or disassemble other components, thereby improving the convenience of the mobile elevator in changing its position, conforming to the installation and use conditions of the mobile house, and meeting the requirements of flexible movement. When the mobile elevator is in normal use, the rope head winder 10 stops working and serves as the rope head fixing part at the other end of the traction rope 7.

[0031] Of course, in order to improve the stability of the counterweight 6 during transportation, a counterweight locking device is provided on the counterweight 6, and a counterweight locking plate is provided on the upper counterweight guide rail 4, and the counterweight locking device is adapted to the counterweight locking plate. When the rope head winder 10 gradually winds up the traction rope 7, so that the counterweight 6 rises to the top floor housing 12, and the counterweight locking device is aligned with the counterweight locking plate, the counterweight locking device is actuated, and cooperates with the counterweight locking plate to lock the counterweight 6 in the top floor housing 12, so that the counterweight 6 can be stably locked to the counterweight guide rail to prevent the counterweight 6 from shaking during transportation. When the mobile elevator is transported to a new placement location, the counterweight locking device is controlled to actuate, disengage from the counterweight locking plate, and release the position lock of the counterweight 6.

[0032] In this embodiment, the rope winder 10 includes a winding motor 101, a worm 102, a worm wheel 103 and a winding wheel 104. The worm 102 is connected to the rotating shaft of the winding motor 101, the worm wheel 103 is connected to the worm 102, the worm wheel 103 is connected to the winding wheel 104 through a connecting shaft 105, and the end of the traction rope 7 is fixedly connected to the winding wheel 104. The winding motor 101 rotates, driving the worm 102 to rotate, the worm 102 drives the worm wheel 103 to rotate, the worm wheel 103 drives the winding wheel 104 to rotate coaxially through the connecting shaft 105, and the rotation of the winding wheel 104 can drive the traction rope 7 to be wound or unwound around the outer periphery of the winding wheel 104. In addition, the winding wheel 104 of the present embodiment is driven by the transmission of the worm wheel 103 and the worm 102. During the winding or unwinding of the traction rope 7, the worm 102 can be used to drive the worm wheel 103 to rotate, so that the winding wheel 104 rotates to realize the winding and unwinding of the traction rope 7. The self-locking effect between the worm wheel 103 and the worm 102 can also be used to prevent the torque generated by the traction rope 7 on the winding wheel 104 from driving the worm 102 through the worm wheel 103, and then driving the winding motor 101 to rotate in the opposite direction, thereby ensuring that the rope end winder 10 can stably and reliably perform the winding and unwinding operations of the traction rope 7.

[0033] Furthermore, the winding wheel 104 includes a wheel body 1041, a rope end fixing plate 1042 and an end face sealing plate 1043, the outer periphery of the wheel body 1041 is provided with a plurality of winding grooves 104A for winding the traction rope 7, the wheel body 1041 is provided with a recessed position 104B for accommodating the rope end fixing plate 1042, and the recessed position 104B is connected with the winding groove 104A; the rope end fixing plate 1042 is provided with a plurality of groups of rope end holes 104f for fixing and connecting the traction rope 7, and each group of rope end holes 104f is provided with two rope end holes 104f. When fixing the end of the traction rope 7, the end of the traction rope 7 enters into one rope end hole 104f, and after passing through the other rope end hole 104f in the reverse direction, the end of the traction rope 7 is fixed and locked on the rope body of the traction rope 7 through the rope end fixing ring, thereby binding the traction rope 7 to the rope end fixing plate 1042. After all the traction ropes 7 are bound to the rope end fixing plate 1042, the rope end fixing plate 1042 is adaptively installed in the recessed position 104B, the traction rope 7 is led out from the position where the recessed position 104B is connected to the winding groove 104A, and then fixedly connected to the end face of the wheel body 1041 through the end face sealing plate 1043, so that the rope end fixing plate 1042 is fixed in the recessed position 104B. Specifically, the recessed position 104B is formed by recessing inward from the end surface of the wheel body 1041, and the recessed position 104B includes a semi-annular groove 104a and an open groove 104b. A central shaft hole 104c for cooperating with the connecting shaft 105 is provided at the center of the wheel body 1041. The central axis of the semi-annular groove 104a coincides with the central axis of the central shaft hole 104c. The semi-annular groove 104a is located between the central shaft hole 104c and the winding groove 104A. The open groove 104b radially connects the semi-annular groove 104a and the outside of the wheel body 1041, and the open groove 104b is connected to the winding groove 104A. The rope end fixing plate 1042 includes a semi-circular plate 104d adapted to the semi-circular groove 104a and a boss 104e adapted to the open groove 104b, wherein the boss 104e is located on the outside of the semi-circular plate 104d, and the outer side surface of the boss 104e is flush with the bottom surface of the winding groove 104A, so that the traction rope 7 can fully enter the winding groove 104A when winding. The rope end hole 104f is opened inward from the outer side surface of the boss 104e, and the rope end hole 104f passes through the inner side of the semi-circular plate 104d. By designing the semi-circular groove 104a in the wheel body 1041 and the semi-circular plate 104d in the rope end fixing plate 1042, the contact area between the rope end fixing plate 1042 and the wheel body 1041 can be greatly increased, thereby ensuring the load-bearing capacity of the rope end fixing plate 1042.

[0034] In this embodiment, the car locking device 14 includes a locking motor 141, a locking gear 142, an upper rack 143, a lower rack 144, a left latch mechanism 145 and a right latch mechanism 146. The locking gear 142 is connected to the rotating shaft of the locking motor 141, the upper rack 143 and the lower rack 144 are respectively meshed with the upper and lower sides of the locking gear 142, one end of the left latch mechanism 145 and the right latch mechanism 146 are respectively connected to the lower rack 144 and the upper rack 143, and the other ends of the left latch mechanism 145 and the right latch mechanism 146 extend to the car locking plate 15 opposite thereto. When the locking motor 141 rotates, the locking gear 142 is driven to rotate, and the locking gear 142 drives the lower rack 144 and the upper rack 143 to move synchronously laterally, thereby driving the left latch mechanism 145 and the right latch mechanism 146 to move synchronously laterally, thereby realizing the locking and unlocking actions of the car 5.

[0035] Furthermore, the left latch mechanism 145 includes an extension rod 1451, a connecting head 1452, a U-shaped plug plate 1453 and a mounting bracket 1454, one end of the extension rod 1451 is connected to the lower rack 144, and the other end is fixedly connected to the U-shaped plug plate 1453 through the connecting head 1452; the U-shaped plug plate 1453 includes two laterally extending lock tongues 145A, one end of the two lock tongues 145A are connected; the other end extends through the mounting bracket 1454 to the car locking plate 15 opposite thereto, the mounting bracket 1454 is fixed on the car 5, and the car locking plate 15 is provided with two lock holes 151 respectively adapted to the two lock tongues 145A. When the rack moves laterally, the U-shaped plug plate 1453 is driven to move laterally through the extension rod 1451 and the connector 1452, and the mounting bracket 1454 is used to limit and support the U-shaped plug plate 1453 so that the U-shaped plug plate 1453 can move laterally stably and smoothly.

[0036] Furthermore, the U-shaped plug plate 1453 is provided with a downwardly recessed sensing recess 145B, and the mounting bracket 1454 is provided with a contact sensor 1455, the sensing end of the contact sensor 1455 is movably matched with the sensing recess 145B, and the transverse length of the sensing recess 145B is equivalent to the transverse movement length of the U-shaped plug plate 1453 when locking or unlocking the car 5. When the U-shaped plug plate 1453 is transversely moved and inserted into the lock hole 151 to lock the position of the car 5, the sensing end of the contact sensor 1455 is separated from the sensing recess 145B, and the top of the U-shaped plug plate 1453 touches the sensing end of the contact sensor 1455, so that the contact sensor 1455 sends a signal to the elevator control system to confirm that the U-shaped plug plate 1453 is inserted into the lock hole 151 and the car 5 is in a locked state. When the U-shaped plug 1453 moves laterally out of the lock hole 151, the position of the car 5 is in the unlocked state. At this time, the sensing end of the contact sensor 1455 cooperates with the sensing recess 145B, the sensing end of the contact sensor 1455 is reset, and the contact sensor 1455 does not send a signal to the outside. The elevator control system determines that the U-shaped plug 1453 leaves the lock hole 151 and the car 5 is in the unlocked state. The contact sensor 1455 is set to feedback the action signal of the car locking device 14. When the feedback signal of the contact sensor 1455 matches the signal executed by the car locking device 14, the elevator control system controls the mobile elevator to execute the next action; otherwise, it stops executing the next action and sends an error prompt signal to the outside.

[0037] In this embodiment, the structure of the right latch mechanism 146 is the same as that of the left latch mechanism 145, and the specific structure of the right latch mechanism 146 will not be described in detail here. Similarly, the structure of the counterweight locking device is the same as that of the car locking device 14, and the structure of the counterweight locking plate is the same as that of the car locking plate 15, and the specific structures of the counterweight locking device and the counterweight locking plate will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means belongs to the protection scope of the present invention.
