[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Figure 1A schematic diagram of the positioning adjustment device in an embodiment of this utility model is shown. The positioning adjustment device includes: a supporting base plate 1 and a Y-axis telescopic mechanism 2 disposed on the supporting base plate 1. The Y-axis telescopic mechanism 2 includes a movable plate 21. A first limiting arm 211 and a second limiting arm 212 are disposed on both sides of the movable plate 21. A limiting area for accommodating the guide rail is formed between the first limiting arm 211 and the second limiting arm 212. The position of the guide rail is limited based on the limiting area of ​​the Y-axis telescopic mechanism, and the guide rail is adjusted in the Y-axis direction by the Y-axis telescopic mechanism to ensure that the guide rail is in an accurate position.

[0028] Specifically, a locking arm 213 is provided on the first limiting arm 211. The locking arm 213 is rotatably disposed at the end of the first limiting arm 211, and one end of the locking arm 213 is engaged with the end of the second limiting arm 212. The Y-axis telescopic mechanism 2 is in a locked state, or one end of the locking arm 213 is located above the first limiting arm 211, and the Y-axis telescopic mechanism 2 is in an open state.

[0029] When the Y-axis telescopic mechanism 2 is in the open state, the first limiting arm 211 and the second limiting arm 212 are driven to move towards the guide rail, thereby changing the relative position between the first limiting arm 211, the second limiting arm 212 and the guide rail. That is, the guide rail can be located within the limiting area formed by the first limiting arm 211 and the second limiting arm 212. By adjusting the locking arm 213, the locking arm 213 connects the first limiting arm 211 and the second limiting arm 212, thereby switching the Y-axis telescopic mechanism 2 from the open state to the locked state to satisfy the positioning and clamping of the guide rail.

[0030] Specifically, Figure 2 A schematic diagram of the Y-axis telescopic mechanism in an embodiment of the present invention is shown. The Y-axis telescopic mechanism 2 includes: a first lead screw transmission assembly 22 disposed on the top surface of the bearing base plate 1; a moving plate 21 connected to the bearing base plate 1 based on the first lead screw transmission assembly 22; and the moving plate 21 is driven to move on the bearing base plate 1 based on the first lead screw transmission assembly 22, thereby realizing the telescopic movement of the moving plate 21 in the Y-axis.

[0031] The first lead screw transmission assembly 22 includes a first slide rail 222 disposed on the top surface of the supporting base plate 1, a first slider 223 disposed on the bottom surface of the moving plate 21, a first transmission lead screw 224 disposed in the middle of the moving plate 21, and a first drive motor 221 connected to the first transmission lead screw 224. The first slider 223 cooperates with the first slide rail 222, that is, the moving plate 21 slides on the first slide rail 222 based on the first slider 223, ensuring that the moving plate 21 can move along the first slide rail 222 on the supporting base plate 1 along the Y-axis.

[0032] The movable plate 21 is sleeved on the first transmission screw 224, and the movable plate 21 is threadedly connected to the first transmission screw 224. When the first drive motor 221 drives the first transmission screw 224 to rotate, the movable plate 21 is restricted in its rotation around the Y-axis due to the sliding engagement of the first slider 223 and the first slide rail 222. This allows the movable plate 21 to move along the first transmission screw 224, cooperating with the first slide rail 222 and the first slider 223 to achieve movement in the Y-axis.

[0033] Furthermore, based on the first drive motor 221 driving the first transmission screw 224 to rotate forward or reverse, the moving direction of the moving plate 21 in the Y-axis direction can be adjusted, thereby realizing the telescopic movement control of the moving plate 21 in the Y-axis direction.

[0034] Furthermore, two first slide rails 222 are provided on the top surface of the supporting base plate 1. The cooperation of the two first slide rails 222 can improve the stability and reliability of the cooperation between the moving plate 21 and the supporting base plate 1.

[0035] Specifically, Figure 3 A schematic diagram of the locking arm structure in an embodiment of the present invention is shown. A rotation mechanism 4 is provided between the first limiting arm 211 and the locking arm 213. The rotation mechanism 4 includes a rotary drive motor 41, a drive gear 42, and a driven gear 43. The rotary drive motor 41 is mounted on the first limiting arm 211 and drives the drive gear 42. The drive gear 42 and the driven gear 43 mesh. The driven gear 43 is rotatably mounted on the end face of the first limiting arm 211, and one end of the locking arm 213 is fixed to the driven gear 43. Based on the rotary drive motor 41 driving the drive gear 42 to rotate, and driving the driven gear 43 to rotate, the locking arm 213 rotates around the driven gear 43.

[0036] Furthermore, the rotary drive motor 41 is mounted on the first limiting arm 211. Based on the rotary drive motor 41 driving the drive gear 42 to rotate, the rotary action mechanism 4 drives the locking arm 213 to deflect towards the second limiting arm 212, thereby realizing the connection between the locking arm 213 and the second limiting arm 212, so that the Y-axis telescopic mechanism is in a locked state, and the guide rail is limited within the limiting area of ​​the Y-axis telescopic mechanism.

[0037] Specifically, the other end of the locking arm 213 is provided with a mating part 2131, and the end of the second limiting arm 212 is provided with a mating groove 2121. When the locking arm 213 is flipped and connected with the second limiting arm 212, the mating part 2131 of the locking arm 213 is engaged in the mating groove 2121 of the second limiting arm 212, so that the locking arm 213 and the second limiting arm 212 are engaged.

[0038] Specifically, a positioning seat 5 is provided at the end of the first transmission screw 224. The positioning seat 5 is fixed on the bearing base plate 1. The end of the positioning seat 5 facing the guide rail is set as a contact surface. When the bearing base plate 1 moves closer to the guide rail, the contact surface of the positioning seat 5 abuts against the guide rail to realize the working positioning between the positioning adjustment device and the guide rail.

[0039] Furthermore, the positioning adjustment device is installed inside the mobile platform. Based on the mobile platform, the position of the positioning adjustment device can be adjusted, that is, the position of the bearing base plate 1 can be adjusted, so that the positioning seat 5 of the positioning adjustment device can abut against the front end face of the guide rail, thereby meeting the processing requirements for guide rail docking and installation.

[0040] Specifically, Figure 4 A schematic diagram of the X-axis telescopic mechanism in an embodiment of the present invention is shown. The positioning adjustment device further includes an X-axis telescopic mechanism 3 disposed on the bottom surface of the bearing base plate 1. The X-axis telescopic mechanism 3 includes a second lead screw transmission assembly and a movable push plate 31. The movable push plate 31 is used to adjust the position of the guide rail in the X-axis direction.

[0041] Specifically, the second lead screw transmission assembly includes a second slide rail 323 disposed on the bottom surface of the bearing base plate 1, a second slider 324 disposed on the movable push plate 31, a second transmission lead screw 322 disposed on the bottom surface of the bearing plate, and a second drive motor 321 connected to the second transmission lead screw 322. The second slider 324 cooperates with the second slide rail 323, that is, the movable push plate 31 slides on the second slide rail 323 based on the second slider 324, ensuring that the movable push plate 31 can move along the second slide rail 323 on the bearing base plate 1 along the X-axis.

[0042] The movable push plate 31 is sleeved on the second transmission screw 322, and the movable push plate 31 is threadedly connected to the second transmission screw 322. When the second drive motor 321 drives the second transmission screw 322 to rotate, the movable push plate 31 is restricted in its rotational freedom around the X-axis due to the sliding engagement of the second slider 324 and the second slide rail 323. This allows the movable push plate 31 to move along the second transmission screw 322, cooperating with the second slide rail 323 and the second slider 324 to achieve movement in the X-axis.

[0043] Furthermore, the movable push plate 31 is provided with a push block 311. When the movable push plate 31 moves based on the drive of the second lead screw transmission assembly, the push block 311 can connect with the guide rail and push the guide rail to move upward along the X-axis, so that the guide rail is located in the accurate installation position.

[0044] Specifically, the working principle of the positioning adjustment device is as follows: During the installation of the elevator guide rail, a first section of guide rail is installed in the elevator shaft as a reference guide rail. The guide rail is vertically arranged along the Z-axis using hoisting equipment, and positioned above the reference guide rail. The positioning seat 5, in conjunction with the reference guide rail, adjusts the position of the positioning adjustment device. The X-axis telescopic mechanism 3 drives the movable push plate 31 closer to the guide rail, and the push block 311 of the movable push plate 31 pushes the guide rail to move, causing the guide rail to correspond and engage with the reference guide rail, thus achieving the adjustment and positioning of the guide rail. By driving the moving plate 21 of the Y-axis telescopic mechanism 2 to move towards the guide rail, the guide rail is completely contained within the limiting area of ​​the Y-axis telescopic mechanism 2. By driving the locking arm 213 to flip through the rotating action mechanism 4, the Y-axis telescopic mechanism 2 is in a closed state. By driving the moving plate 21 to move away from the guide rail, the locking arm 213 abuts against the rear end face of the guide rail. Based on the contact surface of the positioning seat 5 being attached to the front end face of the guide rail, the locking arm 213 and the positioning seat 5 can clamp and fix the guide rail, thereby realizing the positioning and clamping operation of the guide rail, meeting the docking connection requirements between the guide rail and the reference guide rail, and thus improving the accuracy of guide rail installation.

[0045] Furthermore, after the guide rail is connected to the reference guide rail, the Y-axis telescopic mechanism drives the moving plate 21 to move towards the guide rail and drives the locking arm 213 to flip and disengage from the second limiting arm 212, so that the Y-axis telescopic mechanism 2 is in the open state. By adjusting the relative position of the positioning adjustment device and the guide rail, the positioning adjustment device is moved away from the guide rail, and a positioning adjustment operation is performed for the installation of the next guide rail.

[0046] This utility model embodiment provides a positioning adjustment device, which adjusts and positions the guide rail by setting a Y-axis telescopic mechanism 2, limits the guide rail based on the first limiting arm 211, the second limiting arm 212 and the locking arm 213, and clamps and fixes the guide rail with the positioning seat 5, thereby improving the accuracy of the positioning and installation of the guide rail.

[0047] Furthermore, the positioning adjustment device provided by the embodiments of this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
