Description

Technical Field

[0001] The invention relates to the technical field of elevator track laying equipment, and in particular to a light automatic installation guide rail system. Background Art

[0002] Elevator guide rails are two or more vertical or inclined rigid rails installed in the elevator shaft or between floors, ensuring that the car and counterweight move up and down along them, ensuring that the escalator and moving walkway steps move along them in an inclined or horizontal manner, and providing guidance for the elevator car, counterweight device or steps. They are usually called car guide rails and are the main rails. When laying the elevator main rails, the main rails need to be fed;

[0003] The current elevator main rail laying process usually requires manual laying of the main rails. The height inside the elevator shaft is high and the operation is dangerous. Some main rail installation devices need to feed each main rail separately when feeding the main rails, resulting in low installation efficiency and wasted installation time. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of low efficiency and high risk of manual track laying of elevators in the prior art, the present invention provides a light automatic installation guide rail system.

[0005] The technical solution to be adopted by the present invention to solve its technical problems is: a light-duty automatic installation guide rail system, including a rail feeding mechanism arranged at the bottom of a well, wherein a plurality of rails are installed in the rail feeding mechanism, and the rails are formed into a "丄"-shaped rail by cooperating a bottom plate and a vertical plate, and a drilling and installation robot is suspended above the rail feeding mechanism for rotating the rails 180° along the Z axis and then installing them on the side wall of the well. A reference rail vertically fixed to the side wall of the well is provided on one side of the rail feeding mechanism, and a plurality of guide sliders are arranged on the reference rail at intervals along the length direction, and U-shaped grooves cooperating with the rails are provided on the two side walls of the guide sliders which are arranged opposite to each other, and the U-shaped grooves correspond to the position of the discharge port of the rail feeding mechanism, the lowest guide slider is connected to the guide slider above it by a rotating shaft, and steel wire ropes are connected between the remaining adjacent guide sliders, and a first crane for towing the uppermost guide slider and a second crane for towing the drilling and installation robot are provided at the top of the well.

[0006] After installing the reference track at the bottom of the hoistway, a plurality of guiding sliders are configured on the reference track. The second track is inserted into the U-shaped groove of the guiding sliders through the rail feeding mechanism. The uppermost guiding slider is towed by the first crane, and each guiding slider and the track provided on the guiding slider are towed upward along the reference track in a sliding manner. When the track is towed above the reference track, the lowermost guiding slider is still on the reference track. The drilling and installation robot rotates the towed track 180° around the rotating shaft along the Z-axis and then fixes it to the side wall of the hoistway through expansion bolts, completing the fixation of the second track. Subsequently, each guiding slider descends along the second track to the reference track, and the third track is fed into the U-shaped groove of the guiding slider through the rail feeding mechanism. The above steps are repeated to install the third track above the second track, and so on until all the tracks on one side wall of the hoistway are installed. After all the tracks on one side wall of the hoistway are installed, the positions of the rail feeding mechanism, the crane, and the drilling and installation robot are adjusted, and the installation of the tracks on the next side wall of the hoistway continues.

[0007] Further, the rail feeding mechanism includes a frame. A plurality of clamping mechanisms are arranged on the frame at intervals in the vertical direction. The clamping mechanism includes two relatively arranged clamping components. A row of tracks is arranged vertically between the two clamping components. A row of supporting wheels for facilitating the translation of the track along the X-axis is arranged at the bottom of the row of tracks. The clamping component includes a first substrate arranged on the frame. A first telescopic component arranged in the Y-axis direction is arranged at the lower end of the first substrate. A row of first U-shaped frames arranged at intervals in the X-axis direction is arranged at the output end of the first telescopic component. A second telescopic component for driving the second substrate to move in the Y-axis direction is arranged at the upper end of the first substrate. A third telescopic component for driving the third substrate to move in the X-axis direction is arranged at the upper end of the second substrate. A row of second U-shaped frames arranged at intervals in the X-axis direction is arranged on the side of the third substrate close to the track.

[0008] The two clamping components cooperate with each other to clamp the two ends of the track bottom plate through the first U-shaped frame or the second U-shaped frame. The rail feeding mechanism is used to insert the vertical plate of the track into the U-shaped groove of each guiding slider to complete the feeding of the track. In the initial state, the first telescopic component extends to insert each first U-shaped frame into each track bottom plate to fix the positions of the tracks arranged in the frame. When feeding is required, the second telescopic component is driven to drive the second substrate close to the track to insert the second U-shaped frame into each track bottom plate. Then the first telescopic component retracts, and the first U-shaped frame moves away from each track. Next, the third telescopic component extends to move each track closer to the reference track. After the track to be fed closest to the reference track is inserted into the U-shaped groove of the guiding slider, the feeding is completed. Subsequently, the first telescopic component extends to fix the positions of the tracks arranged in the frame, the second telescopic component contracts to move the second U-shaped frame away from each track, and finally the third telescopic component contracts to complete the reset and wait for the next feeding.

[0009] Further, in order to prevent friction between the track and the U-shaped groove, a plurality of rollers are provided on the bottom wall and the side wall of the U-shaped groove. In order to prevent the track from disengaging from the U-shaped groove, a plurality of magnets cooperating with the track are provided on the bottom wall of the U-shaped groove.

[0010] Further, after the track on one side wall of the hoistway is laid, it is necessary to separate the guiding slider from the installed track. In order to facilitate the separation of the track from the guiding slider, a separation assembly is provided on the guiding slider. The separation assembly includes a driving motor provided on one side of the guiding slider. A driving disc is provided at the output end of the driving motor. A driving rod is slidably connected to the bottom wall of the U-shaped groove. An intermediate shaft is hinged between the driving disc and the driving rod. By driving the driving disc to rotate by the driving motor and transmitting through the intermediate shaft, the telescoping of the driving rod is realized. When the driving rod extends, the track is extruded out of the U-shaped groove of the guiding slider, so as to remove the guiding slider from the track.

[0011] Further, the punching and installation robot includes a main frame. Support mechanisms are provided on both sides of the main frame. The support mechanisms include support wheels and support claws. A hydraulic cylinder is provided between the support claws and the main frame. An elastic torsion spring is provided between the support wheels and the main frame. A first universal robot and a second universal robot are slidably arranged on the main frame along the Y-axis direction. A clamping cylinder cooperating with the track is connected to the output end of the first universal robot. A screwdriver is connected to the output end of the second universal robot.

[0012] When the second hoist pulls the punching and installation robot to move up and down in the hoistway, the support wheels cooperate with the side wall of the hoistway to ensure the stability of the punching and installation robot during movement; when the punching and installation robot moves to a suitable position, the hydraulic cylinder drives the support claws to extend to fix the position of the punching and installation robot, so as to facilitate the normal and stable operation of the first universal robot and the second universal robot.

[0013] The first universal robot grabs the lifted track, rotates the track 180° along the Z-axis with the rotating shaft as the center, and then presses it against the side wall of the hoistway. The second universal robot fixes the lifted track to the upper end of the previous track by driving screws with the screwdriver.

[0014] Further, nail storage plates are provided on both sides of the main frame, and a number of expansion screws are inserted into the nail storage plates.

[0015] Further, in order to ensure the stability of the punching and installation robot during lifting in the hoistway, wall-following wheels are provided on the side of the main frame.

[0016] The beneficial effects of the present invention are as follows: A lightweight automatic installation guide rail system provided by the present invention uses a rail feeding mechanism to sequentially feed vertically arranged rails. In cooperation with a crane and a guiding slider, the rails are fed to the installation position from bottom to top in sequence. The punching and installation robot rotates the rail 180° along the Z-axis and then fixedly installs it on the side wall of the shaft. It has a high degree of automation, good laying quality, and high installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Preparatory work in the early stage:

[0033] Install a first hoist 6 and a second hoist 7 at the top of the shaft 1; after installing the reference track 31 at the bottom of the shaft 1, configure a plurality of guiding sliders 5 on the reference track 31. The guiding sliders 5 are connected by a steel wire rope 53. The uppermost guiding slider 5 is connected to the first hoist 6, and the second hoist 7 is connected to the main frame 41 of the punching and installation robot 4. Install the frame 21 of the rail feeding mechanism 2 on one side of the reference track 31, and the material outlet is arranged corresponding to the reference track 31.

[0034] Rail installation process:

[0035] In the initial state, the first telescopic assembly extends to insert each first U-shaped frame 26 into the bottom plate of each track 3 to fix the positions of the tracks 3 arranged in the frame 21.

[0036] When feeding is required, the second telescopic assembly is driven to move the second base plate 24 close to the track 3 to insert the second U-shaped frame 27 into the bottom plate of each track 3. Then the first telescopic assembly retracts, and the first U-shaped frame 26 moves away from each track 3. Then the third telescopic assembly extends to move each track 3 close to the reference track 31. After the track 3 to be fed closest to the reference track 31 is inserted into the U-shaped groove 51 of the guiding slider 5, the feeding is completed. Subsequently, the first telescopic assembly extends, and the second telescopic assembly and the third telescopic assembly contract and reset in sequence, waiting for the next feeding.

[0037] The uppermost guiding slider 5 is towed by the first hoist 6 to tow each guiding slider 5 and the second track 3 loaded onto the guiding slider 5 upward. When the second track 3 is towed above the reference track 31, the lowermost guiding slider 5 is still on the reference track 31. The first omnidirectional robot 44 clamps the track 3 through the clamping cylinder 46 and rotates the towed track 3 by 180° to closely adhere to the side wall of the shaft 1. Then, the second omnidirectional robot 45 grabs expansion screws through the screwdriver 47 and fixes the second track 3 on the side wall of the shaft 1;

[0038] Subsequently, each guiding slider 5 descends along the second track 3 to the reference track 31. The third track 3 is loaded into the U-shaped groove 51 of the guiding slider 5 through the track feeding mechanism 2. The above steps are repeated to install the third track 3 above the second track 3, and so on until all the tracks 3 on one side wall of the shaft 1 are installed. After all the tracks 3 on one side wall of the shaft 1 are installed, the positions of the track feeding mechanism 2, the hoist, and the drilling and installation robot 4 are adjusted, and the installation of the tracks 3 on the next side wall of the shaft 1 continues.
