Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail installation technology, and in particular to an elevator guide rail quick installation and positioning device. Background Technology

[0002] The elevator car and counterweight move up and down along the guide rails. If the guide rails are not accurately positioned and their verticality cannot be guaranteed, the car will sway during operation. Therefore, a positioning device for installing elevator guide rails, disclosed in CN220485266U, is proposed. This device uses four reels, each connected to a rotating shaft and positioned on the side of the rotating shaft furthest from the motor. Each reel has a baffle fixedly connected to both sides. The rotation of the rotating shafts drives the reels to rotate, which in turn winds up or unwinds the wire rope, thus raising or lowering the worktable. When installing the elevator guide rails, the positioning blocks are pre-installed at the bottom of the support base, and then laser emitters are installed in the positioning slots. The lasers emitted by the two laser emitters on each positioning block are positioned on both sides of the elevator guide rail to be installed, thereby completing the positioning of the elevator guide rails.

[0003] However, the movement and operation of the installer on the workbench (such as moving the guide rails, using tools, etc.) will generate forces, causing the workbench to shake. The laser emitter needs to be precisely aligned with both sides of the elevator guide rail to be installed. The shaking of the workbench will cause the laser emitter's emission direction to change, thus affecting its positioning accuracy. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a quick installation and positioning device for elevator guide rails.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rapid installation and positioning device for elevator guide rails, comprising a workbench, several laser emitting modules, a laser receiving module, and an infrared transmitter. The laser emitting modules are installed around the bottom of the elevator shaft and are respectively positioned close to the elevator guide rail installation location. Mounting seats are fixedly installed on both sides of the upper surface of the workbench near the elevator guide rail. Two horizontally distributed frames are fixedly installed in the mounting seats. Two sliders are slidably installed in the horizontal frames. Rollers for abutting against the inner wall of the elevator shaft are movably installed on the sides of the two sliders in the upper horizontal frame. A retaining ball is movably installed on the side of the slider in the lower horizontal frame. A connecting tube is fixedly installed through the surface of the retaining ball. A laser receiving module and an infrared transmitter are provided at the top and bottom of the outer side of each connecting tube.

[0006] Preferably, a horizontally positioned electric push rod is provided between the roller and the corresponding slider.

[0007] Preferably, a horizontally arranged electric telescopic rod is fixedly installed on the side of the slider in the lower horizontal frame, and the telescopic end of the electric telescopic rod is arranged in a ring shape and a ball is rolled and installed in the telescopic end of the electric telescopic rod.

[0008] Preferably, a bidirectional lead screw is rotatably connected within the horizontal frame at the upper position, and the two ends of the bidirectional lead screw are threaded through two sliders within the same horizontal frame.

[0009] Preferably, the horizontal frame at the lower position is rotatably connected to the inner sidewall with screws, and the two screws in the same horizontal frame are coaxial at their opposite end faces and rotatably connected, and are threaded through the two sliders in the same horizontal frame respectively.

[0010] Preferably, a counterweight block for mounting an infrared transmitter is fixedly installed on the bottom edge of the outer wall of the connecting pipe, and a counterweight rod is fixedly installed on the other side of the top of the counterweight block.

[0011] Preferably, the counterweight is coaxially arranged with the connecting pipe, and the counterweight rod and infrared emitter on the counterweight are symmetrically distributed about the connecting pipe and have equal weight and shape.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the distance between the two sliders in the horizontal frame at the top position is adjusted by moving them, and the rollers on the sliders are moved to abut against the inner wall of the elevator shaft, so that the workbench can be fixed in the elevator shaft to prevent the workbench from shaking. The position of the infrared transmitter can be quickly adjusted by using the combination of the laser emitting module and the laser receiving module. The infrared laser line generated by the infrared transmitter is set to fit the surface of the elevator guide rail, which facilitates quick positioning when installing the elevator guide rail.

[0014] 2. In this utility model, by setting a retaining ball, because the surface of the retaining ball is arc-shaped, the connecting tube always remains vertical under the action of gravity, regardless of the tilt of the worktable. The set counterweight ensures that the connecting tube naturally falls to a vertical state under the rolling action of the retaining ball, and the set counterweight rod can achieve weight balance on both sides of the counterweight.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, an elevator guide rail quick installation and positioning device includes a workbench 6, several laser emitting modules 1, laser receiving modules 5, and infrared transmitters 2. Several laser emitting modules 1 are installed around the bottom of the elevator shaft and are respectively set close to the elevator guide rail installation position. Several laser emitting modules 1 generate upward laser lines that are parallel to the elevator guide rail installation direction. The workbench 6 can be lifted by a commonly used elevator traction machine to realize the lifting and lowering of the workbench 6 in the elevator shaft.

[0023] Mounting seats 7 are fixedly installed on both sides of the upper surface of the workbench 6 near the elevator guide rail. Two horizontally arranged frames 16 are fixedly installed inside the mounting seats 7. Two sliders 14 are slidably installed inside the horizontal frames 16. Rollers 15 are movably installed on the sides of the two sliders 14 in the upper horizontal frame 16 to abut against the inner wall of the elevator shaft. A horizontally positioned electric push rod 9 is provided between the rollers 15 and the corresponding sliders 14. The two sliders 14 in the upper horizontal frame 16 are moved to adjust their spacing, and the electric push rod 9 on the sliders 14 extends and retracts to move the rollers 15 until they abut against the inner wall of the elevator shaft. This fixes the workbench 6 inside the elevator shaft, preventing it from shaking.

[0024] A ball bearing 4 is movably mounted on the side of the slider 14 inside the horizontal frame 16 at the lower position. A connecting tube 11 is fixedly mounted through the surface of the ball bearing 4. A laser receiving module 5 and an infrared emitter 2 are provided at the top and bottom of the outer side of each connecting tube 11. A horizontally arranged electric telescopic rod 8 is fixedly mounted on the side of the slider 14 inside the horizontal frame 16 at the lower position. The telescopic end of the electric telescopic rod 8 is arranged in a ring shape, and the ball bearing 4 is rolled inside the telescopic end of the electric telescopic rod 8. The connecting tube 11 generates a pulling force on the lower end of the ball bearing 4. Because the surface of the ball bearing 4 is arc-shaped, the connecting tube 11 always remains vertical under the action of gravity, regardless of the inclination of the worktable 6. The slider 14 is used to... The longitudinal position of the ball 4 is adjusted within the lower horizontal frame 16, and the lateral position of the ball 4 is adjusted by extending and retracting the electric telescopic rod 8 until the laser receiving module 5 at the top of the connecting pipe 11 receives the laser line emitted by the laser emitting module 1 directly below. At this time, the infrared emitting device 2 installed on the surface of the connecting pipe 11 emits infrared rays vertically upward, which is convenient for personnel to refer to when installing the elevator guide rail. In this solution, by reasonably distributing the installation position of the laser emitting module 1 and the position of the infrared emitting device 2 relative to the connecting pipe 11, the infrared laser line generated by the infrared emitting device 2 is set to fit against the surface of the elevator guide rail after the laser receiving module 5 and the laser emitting module 1 are aligned, which is convenient for personnel to adjust the installation position of the elevator guide rail.

[0025] A bidirectional lead screw 12 is rotatably connected inside the upper horizontal frame 16, with both ends of the bidirectional lead screw 12 threaded through two sliders 14 within the same horizontal frame 16. Screws 13 are rotatably connected to the inner sidewalls of the lower horizontal frame 16. The two screws 13 within the same horizontal frame 16 have coaxial end faces and are rotatably connected, threaded through two sliders 14 within the same horizontal frame 16. In this design, one and two stepper motors can be installed on the sides of the upper and lower horizontal frames 16, respectively, meaning three stepper motors are used to drive the bidirectional lead screw 12 and the two screws 13 to rotate. This allows the two sliders 14 within the upper horizontal frame 16 to move relative to or towards each other, and the two sliders 14 within the lower horizontal frame 16 to move independently.

[0026] A counterweight 3 for mounting an infrared transmitter 2 is fixedly installed on the bottom edge of the outer wall of the connecting pipe 11. A counterweight rod 10 is fixedly installed on the other side of the top of the counterweight 3. The counterweight 3 and the connecting pipe 11 are coaxially arranged, and the counterweight rod 10 on the counterweight 3 and the infrared transmitter 2 are symmetrically distributed about the connecting pipe 11 and have the same weight and shape. The counterweight 3 ensures that the connecting pipe 11 naturally falls to a vertical state under the rolling action of the ball 4, while the counterweight rod 10 can achieve weight balance on both sides of the counterweight 3.

[0027] Working principle: During use, several laser emitting modules 1 are installed around the bottom of the elevator shaft and are positioned close to several elevator guide rail installation positions. The laser emitting modules 1 generate laser lines that are vertically upward and parallel to the installation direction of the elevator guide rails. The laser emitting modules 1 are distributed at a certain distance from the corresponding elevator guide rails. After the worktable 6 is pulled up and down to a fixed position inside the elevator shaft by the elevator traction machine, the two sliders 14 in the upper horizontal frame 16 move and the electric push rod 9 on the slider 14 extends and retracts to push the roller 15 to move to abut against the inner wall of the elevator shaft, thus fixing the worktable 6 inside the elevator shaft. Then, the sliders 14 in the lower horizontal frame 16 move longitudinally and the electric telescopic rod 8 extends and retracts to adjust the lateral position of the locking ball 4 until the laser receiving module 5 at the top of the connecting tube 11 receives the laser line emitted by the laser emitting module 1 directly below. At this time, the infrared emitter 2 installed on the surface of the connecting tube 11 emits infrared rays that are vertically upward and attached to the expected position on the surface of the elevator guide rail, which facilitates quick positioning when installing the elevator guide rails.

[0028] The wiring diagrams for the laser emitting module 1, infrared transmitter 2, laser receiver module 5, electric telescopic rod 8, electric push rod 9, and stepper motor in this utility model are common knowledge in the field. Their working principles are well-known technologies. The appropriate model is selected based on actual use. Therefore, the control methods and wiring layouts for the laser emitting module 1, infrared transmitter 2, laser receiver module 5, electric telescopic rod 8, electric push rod 9, and stepper motor will not be explained in detail. The laser emitting module 1 can be a Huawei laser radar emitting module, the laser receiver module 5 can be an APD (avalanche photodiode) receiver module, and the infrared transmitter 2 can be a commonly available infrared laser pointer.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
