[0042] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although 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 described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0043] like Figures 1 to 6 As shown, the embodiment of the present invention provides an elevator car assembly and docking auxiliary machine, including: a first base 1; a second base 2, located on one side of the first base 1, cooperating with the first base 1 to work; a universal wheel 3, fixedly connected to the lower surface of the first base 1, so that the first base 1 moves; a top plate 4, located above the first base 1, to lift and align the car; a telescopic rod 5, fixedly connected to the upper surface of the first base 1, so that the top plate 4 can move up and down stably; a bidirectional screw 6, rotatably connected to the inner wall of the first base 1, to drive the top plate 4 to move up and down; a double-section folding rod 9, threadedly connected to the arc surface of the bidirectional screw 6, one end of the double-section folding rod 9 is fixedly connected to the top plate 4, and cooperates with the bidirectional screw 6 to support the top plate 4 to move up and down; an adjusting device 7, arranged on the surface of the first base 1, to fine-tune the distance between the first base 1 and the second base 2 and fix it; a supporting device 8, arranged on the surface of the first base 1, to enable the auxiliary machine to be stably parked on an uneven ground.

[0044] like Figures 2 to 5As shown, the adjusting device 7 includes a turntable 73, which is rotatably connected to the first base 1, and an adjusting screw 71 is fixedly connected to the surface of the turntable 73. The adjusting screw 71 is threadedly connected to the second base 2, and a rubber sleeve 74 is fixedly connected to the surface of the turntable 73. When an auxiliary machine is needed to splice the elevator car, the staff pushes the first base 1 and the second base 2 to the specified position, and drives the double-section folding rod 9 to lift the top plate 4 by rotating the bidirectional screw 6. When the top plate 4 moves up and down, the telescopic rod 5 will extend and contract accordingly. The operation method of the devices on the first base 1 and the second base 2 is the same. After adjusting the position of the top plates 4 on the two bases to the appropriate angle, the staff can control the position of the adjusting screw 71 in the second base 2 by rotating the turntable 73. The surface of the turntable 73 is provided with a rubber sleeve 74, which can provide the necessary friction, thereby achieving fine adjustment of the distance between the second base 2 and the first base 1 and making adjustments between the two bases. The screw thread 71 of the embodiment of the present invention is fixed in the shape of a circle 77 and the center of the circle 78 is fixed in the shape of a circle 77. The movement of the adjusting screw 71 can effectively ensure that the car assembly is in the appropriate position and height during the assembly process, so that the auxiliary machine can efficiently realize the precise assembly and docking of the elevator car, thereby improving the assembly quality and efficiency. The surface of the second base 2 is fixedly connected with a fixing ring 77, and the inner wall of the fixing ring 77 is fixedly connected with bristles 78. When the adjusting screw 71 rotates, the bristles 78 in the fixing ring 77 brush the thread lines in the adjusting screw 71. The inner wall of the second base 2 is provided with a circular hole 76. The size of the circular hole 76 is adapted to the size of the guide rod 72 and is slidably connected. The circular hole 76 provided on the inner wall of the second base 2 is adapted to the size of the guide rod 72. When the adjusting screw 71 rotates, the guide rod 72 slides in the circular hole 76. The inner wall of the guide rod 72 is rotatably connected with a ball 75, and the ball 75 is slidably connected to the circular hole 76. Since the inner wall of the guide rod 72 is connected with the ball 75, the rotation of the ball 75 in the guide rod 72 further reduces friction.

[0045] In the embodiment of the present utility model, when an auxiliary machine is needed to splice the elevator car, the staff pushes the first base 1 and the second base 2 to the specified position, and drives the double-section folding rod 9 to lift the top plate 4 by rotating the bidirectional screw 6. When the top plate 4 moves up and down, the telescopic rod 5 will expand and contract accordingly. The operation method of the devices on the first base 1 and the second base 2 is the same. After adjusting the position of the top plates 4 on the two bases to a suitable angle, the staff can control the position of the adjusting screw 71 in the second base 2 by rotating the turntable 73. The surface of the turntable 73 is provided with a rubber sleeve 74, which can provide the necessary friction, thereby achieving fine adjustment of the second base 2 and the first The spacing between the bases 1 is adjusted, and the two bases are fixed. The movement of the adjusting screw 71 can effectively ensure that the car assembly is in the appropriate position and height during the assembly process. When the adjusting screw 71 rotates, the bristles 78 in the fixing ring 77 brush the thread lines in the adjusting screw 71. The circular hole 76 opened on the inner wall of the second base 2 is adapted to the size of the guide rod 72. When the adjusting screw 71 rotates, the guide rod 72 slides in the circular hole 76. Since the inner wall of the guide rod 72 is connected to the ball 75, the rotation of the ball 75 in the guide rod 72 further reduces the friction, so that the auxiliary machine can efficiently realize the precise assembly and docking of the elevator car, thereby improving the assembly quality and efficiency.

[0046] like Figure 6 As shown, the supporting device 8 includes a fixing block 81, which is detachably mounted on the first base 1. The inner wall of the fixing block 81 is threadedly connected to a long screw rod 82, and one end of the long screw rod 82 is fixedly connected to a stop block 83. When an auxiliary machine is used to assemble the elevator car at a position where the ground is uneven, the fixing block 81 is detachably connected to the first base 1. The internal threaded structure allows the long screw rod 82 to adjust its height by rotation. The stop block 83 fixedly connected to one end of the long screw rod 82 can effectively support and position the car assembly during the adjustment process to ensure that it remains stable during assembly and docking, so as to ensure that the first A base 1 and a second base 2 are aligned horizontally so that the positions of the components to be assembled are precisely aligned. The inner wall of the fixed block 81 is threadedly connected with a short screw rod 84, and one end of the short screw rod 84 is against the surface of the first base 1. At the same time, the short screw rod 84 arranged in the fixed block 81 is also in contact with the surface of the first base 1, so that the fixed block 81 is fixed on the first base 1. One end of the long screw rod 82 and the short screw rod 84 is fixedly connected with a screw block 85, and one end of the long screw rod 82 and the short screw rod 84 is fixedly connected with the screw block 85. By rotating these screw blocks 85, the height of the short screw rod 84 and the long screw rod 82 in the fixed block 81 can be adjusted.

[0047] In an embodiment of the present utility model, when an auxiliary machine is used to splice the elevator car at a location with an uneven ground, the fixed block 81 is connected to the first base 1 in a detachable manner, and the internal threaded structure allows the long screw rod 82 to adjust its height by rotation. The block 83 fixedly connected at one end of the long screw rod 82 can effectively support and position the car assembly during the adjustment process to ensure that it remains stable during assembly and docking. At the same time, the short screw rod 84 arranged in the fixed block 81 also contacts the surface of the first base 1, so that the fixed block 81 is fixed on the first base 1, and one end of the long screw rod 82 and the short screw rod 84 are fixedly connected to the screw block 85. By rotating these screw blocks 85, the height of the short screw rod 84 and the long screw rod 82 in the fixed block 81 can be adjusted to ensure that the first base 1 and the second base 2 are horizontally aligned during the assembly process, so that the positions of the components to be assembled are accurately aligned.

[0048] 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 described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
