Description

Technical Field

[0001] The invention relates to an elevator guide rail installation calibration device and method, belonging to the technical field of elevator installation. Background Art

[0002] With the acceleration of urbanization, the construction of high-rise and super high-rise buildings in my country has ushered in new development opportunities and has become the main battlefield for high-rise building construction in the world. This type of building not only represents the city's skyline, but also puts forward higher requirements for the internal vertical transportation system, especially the widespread application of high-speed elevators has become an inevitable trend. As a key device connecting floors, the carrying efficiency of high-speed elevators and the riding experience of passengers are directly related to the overall operating efficiency and comfort of the building.

[0003] In the elevator system of high-rise and super high-rise buildings, the elevator guide rail is a key component that supports and guides the elevator car up and down. Its installation accuracy directly affects the smoothness, safety and comfort of the elevator operation. Due to the high requirements of high-rise and super high-rise buildings for the carrying speed of elevators, the elevator guide rails not only need to withstand higher operating speeds and greater dynamic loads, but also need to maintain extremely low vibration and noise levels during high-speed operation, which poses an extremely stringent challenge to the installation accuracy of the guide rails.

[0004] However, there are several problems that need to be solved in the current installation process of elevator guide rails:

[0005] 1. Labor intensity challenges caused by the increase in guide rail material and weight: To meet the needs of high-speed operation, the guide rails used in high-speed elevators often have higher weight and stiffness. Compared with the guide rails of ordinary high-rise building elevators, their weight and stiffness have increased by 5% to 10%. This change has significantly increased the labor intensity of the installation workers, and has put forward higher requirements on the installers' physical strength, skills and work efficiency.

[0006] 2. Long installation period and time-consuming calibration and adjustment: During the installation of elevators in high-rise and super-high-rise buildings, the calibration and adjustment of the guide rails after installation is one of the most time-consuming links, accounting for about 20% of the entire elevator construction time, and this proportion will further increase as the building height increases. This not only prolongs the construction period and increases the project cost, but also affects the overall delivery progress of the building.

[0007] 3. Insufficient accuracy of manual installation and calibration: Traditional manual installation and calibration methods are limited by the operator's skill level, physical condition and environmental factors, and it is difficult to achieve the extremely high accuracy requirements required for high-speed elevator operation. Insufficient accuracy will lead to increased vibration and noise during elevator operation, which will affect the comfort of passengers and may even threaten the safe operation of the elevator.

[0008] In addition, even if the existing elevator guide rail installation calibration device can alleviate the problems existing in the above elevator guide rail installation process to a certain extent, the existing elevator guide rail installation calibration device is a rigid connection structure, and all adopts a rigid clamping method for the elevator guide rail. When clamping the elevator guide rail, it will bring about the stress concentration problem caused by the clamping of the structure itself. Due to the reasons of structure, assembly and force, the structure of the calibration device will be deformed, and it will not be able to adapt to the torque generated when clamping the elevator guide rail, which will reduce the stability of the calibration device's own assembly, and cannot meet the parallelism requirements of the guide rail calibration, and the calibration accuracy is low.

[0043] like Figure 1-Figure 4As shown, the present application provides an elevator guide rail installation and calibration device, which in some embodiments includes a first mounting seat 6, which is installed on a construction platform of the elevator shaft, and a sliding guide rail module 5 is installed on the first mounting seat 6. A lifting mechanism 4 is slidably connected to the sliding guide rail module 5, and the lifting mechanism 4 can move along the Y-axis direction on the sliding guide rail module 5. The lifting mechanism 4 is connected to a wall-supporting mechanism 1, and the lifting mechanism 4 is used to drive the wall-supporting mechanism 1 to move along the Z-axis direction. The wall-supporting mechanism 1 is connected to a calibration mechanism 2 for clamping the elevator guide rail 8, and the calibration mechanism 2 is connected to a guide rail measuring mechanism 3.

[0044] The elevator guide rail installation and calibration device provided in this embodiment of the present application is installed on the construction platform of the elevator shaft through the first mounting seat 6. By adjusting the sliding guide rail module 5 and the lifting mechanism 4, a suitable position is found to support the wall support mechanism 1 to the wall of the elevator shaft and fix it. The elevator guide rails 8 at both ends are clamped respectively by two sets of calibration mechanisms 2, and the sample line 7 is measured by the guide rail measuring mechanisms 3 at both ends. The calibration mechanism 2 adjusts the position of the elevator guide rail 8 in real time, thereby calibrating the installation accuracy of the elevator guide rail 8.

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the lifting mechanism 4 is a linear module, including a lifting drive mechanism 41 and a lifting plate 42 connected thereto, the lifting drive mechanism 41 is used to drive the lifting plate 42 to move along the Z-axis direction, and a third connecting shaft 43 is fixedly connected to the lifting plate 42.

[0046] In this embodiment, the elevator guide rail installation calibration device can drive the wall support mechanism 1, the calibration mechanism 2, and the guide rail measuring mechanism 3 to move up and down through the lifting mechanism 4, thereby adjusting the height position of the elevator guide rail installation calibration device. Exemplarily, the lifting drive mechanism 41 can be a rotary motor, etc., which is not specifically limited.

[0047] like Figure 1-Figure 5 As shown, in some embodiments, the wall-supporting mechanism 1 includes a second linear module 15, and the second linear module 15 includes a second driving mechanism 151 and a telescopic member 152 connected thereto, and the second driving mechanism 151 is used to drive the telescopic member 152 to perform telescopic movement.

[0048] In this embodiment, the wall support mechanism 1 drives the telescopic member 152 to perform telescopic movement through the second driving mechanism 151 of the second linear module 15. When the second driving mechanism 151 drives the telescopic member 152 to extend, the extended telescopic member 152 abuts against and is fixed to the hoistway wall, thereby supporting the wall support mechanism 1 to the hoistway wall; when the second driving mechanism 151 drives the telescopic member 152 to retract, the retracted telescopic member 152 is away from the hoistway wall, so that the elevator guide rail installation calibration device can move normally in the elevator hoistway. Exemplarily, the second driving mechanism 151 can be a rotary motor, etc., which is not specifically limited.

[0049] Furthermore, a first guide rail 16 is provided on a side of the second linear module 15 close to the lifting mechanism 4, the first guide rail 16 is slidably connected to a first slider 13, the first slider 13 is fixedly connected to an articulated seat 14, and the third connecting shaft 43 of the lifting mechanism 4 is hinged to the articulated seat 14 of the second linear module 15 close to the lifting mechanism 4; two articulated seats 14 are fixedly connected to the side of the second linear module 15 away from the lifting mechanism 4, and the first linear module 11 is hinged on the two articulated seats 14 on the side of the second linear module 15 away from the lifting mechanism 4, and the first linear module 11 includes a first driving mechanism 111 and a first sliding member 112 connected thereto, the first sliding member 112 is fixedly connected to the first connecting shaft 12, and the first driving mechanism 111 is used to drive the first sliding member 112 and the first connecting shaft 12 to move.

[0050] In this embodiment, since the first guide rail 16 is slidably connected to the first slider 13, the wall-supporting mechanism 1 can slide within a certain range on the lifting mechanism 4, and since the third connecting shaft 43 of the lifting mechanism 4 is hinged to the hinge seat 14 of the second linear module 15, the wall-supporting mechanism 1 and the lifting mechanism 4 are hinged and slidably connected; further, the wall-supporting mechanism 1, the calibration mechanism 2 and the lifting mechanism 4 are all hinged and slidably connected. This connection method has the following two advantages: on the one hand, the wall-supporting mechanism 1 and the calibration mechanism 2 can rotate around the lifting mechanism 4 by a certain angle, and can slide a certain distance relative to the lifting mechanism 4 to adapt to different installation positions in the elevator shaft; on the other hand, this hinged and slidable flexible connection method can release the stress concentration generated by the structure of the elevator guide rail installation calibration device itself when the calibration mechanism 2 clamps the elevator guide rail 8 to a certain extent, and can avoid structural deformation caused by assembly and force.

[0051] Furthermore, the number of the sliding guide rail modules 5, the lifting mechanism 4, the wall support mechanism 1 and the calibration mechanism 2 are two each, the number of the first linear modules 11 is four, the two sliding guide rail modules 5 are installed side by side on the first mounting seat 6, the two wall support mechanisms 1 are arranged opposite to each other, and the second linear modules 15 of the two wall support mechanisms 1 are connected by a connecting frame 17.

[0052] like Figure 1-Figure 10 As shown, in some embodiments, the calibration mechanism 2 includes a mounting frame 21, and the mounting frame 21 is hinged to the first connecting axis 12 on the two first linear modules 11 of the wall-supporting mechanism 1, and the first linear module 11 is used to drive the calibration mechanism 2 to move, and the second linear module 15 is hinged to the two first linear modules 11, and the two first linear modules 11 are hinged to the mounting frame 21 so that the second linear module 15 and the mounting frame 21 form a quadrilateral structure, thereby making the wall-supporting mechanism 1 and the calibration mechanism 2 form a quadrilateral structure, and the two wall-supporting mechanisms 1 are respectively connected to the two calibration mechanisms 2 to form two groups of quadrilateral structures.

[0053] in, Fig.10 The dotted box in the figure represents a set of quadrilateral structures consisting of a wall supporting mechanism 1 and a calibration mechanism 2 connected thereto. Fig.10The four dotted circles in represent the four hinge points of the quadrilateral structure respectively. The elevator guide rail installation calibration device provided by the present application, its second linear module 15 is hinged with the two first linear modules 11, and the two first linear modules 11 are hinged with the mounting frame 21 so that the second linear module 15 and the mounting frame 21 form a quadrilateral structure, so that the wall support mechanism 1 and the calibration mechanism 2 form a quadrilateral structure, and the two wall support mechanisms 1 are respectively connected with the two calibration mechanisms 2 to form two groups of quadrilateral structures, so that the elevator guide rail installation calibration device is designed as a flexible and adjustable quadrilateral structure, which can adapt to the torque generated when clamping the elevator guide rail 8, ensure the stability of the calibration device's own assembly, and improve the calibration accuracy. Specifically, no matter how the quadrilateral structure is subjected to force, its movement will be carried out in accordance with the quadrilateral, which can ensure the calibration accuracy of the elevator guide rail 8. The quadrilateral structure can realize movement in the X-axis and Y-axis directions, can avoid structural deformation of the calibration device caused by structure, assembly and force, can meet the parallelism requirements of the guide rail calibration, and improve its own accuracy. The elevator guide rails 8 on both sides are clamped and calibrated by two sets of independent quadrilateral structures, which avoids the stress concentration problem caused by the hard-connected entire calibration device clamping two elevator guide rails 8 at the same time, and can release the stress concentration generated by the structure itself when clamping, so that the stress generated when the calibration device clamps the elevator guide rail 8 is released by the hinged quadrilateral structure, which alleviates the structural deformation of the calibration device during the assembly process to a certain extent. In addition, the auxiliary deflection measurement sensors 37 on both sides can repeatedly calibrate the parallelism between the two elevator guide rails 8, further improving the installation calibration accuracy of the elevator guide rails 8.

[0054] Furthermore, the mounting frame 21 is fixedly connected to a third linear module 22, and the third linear module 22 is drivingly connected to a reinforcing plate 23, and the reinforcing plate 23 is fixedly connected to a second mounting seat 26. The third linear module 22 is used to drive the reinforcing plate 23 and the second mounting seat 26 to move, and the second mounting seat 26 is hingedly connected to a clamping assembly 24 for clamping and fixing the elevator guide rail 8 through a second connecting shaft 25. The clamping assembly 24 includes a third driving mechanism 241 hinged to the second mounting seat 26, a first moving block 242 and a second moving block 243 drivingly connected to the third driving mechanism 241, and an embracing frame 244 connected to the second moving block 243; the third driving mechanism 241 is used to drive the first moving block 242 and the second moving block 243 to approach or move away from each other, so as to clamp and fix the elevator guide rail 8 between the first moving block 242 and the second moving block 243 or release the elevator guide rail 8, and the embracing frame 244 surrounds and fixes the elevator guide rail 8.

[0055] In this embodiment, the third linear module 22 drives the clamping assembly 24 to move along the X-axis direction, the third driving mechanism 241 drives the first moving block 242 and the second moving block 243 to move toward each other along the Y-axis direction, and the provided embracing frame 244 surrounds and fixes the elevator guide rail 8, which can prevent the clamping assembly 24 from detaching from the elevator guide rail 8 on the one hand, and prevent the guide rail measuring mechanism 3 from being vibrated, loosened, and falling off on the other hand. Exemplarily, the third driving mechanism 241 is a slide module.

[0056] Among them, the clamping component 24 is hinged to the second mounting seat 26 through the second connecting shaft 25, so that the third linear module 22 and the clamping component 24 are in a hinged flexible connection relationship. When the third linear module 22 drives the clamping component 24 to move along the X-axis direction, the clamping component 24 can rotate around the third linear module 22. On the one hand, this design can release the stress concentration generated by the structure of the clamping component 24 itself when the clamping component 24 clamps the elevator guide rail 8 to a certain extent, and can avoid the deformation of the clamping component 24 structure caused by assembly and force; on the other hand, the hinged connection mode of the clamping component 24 at the end of the installation calibration device can realize the quadrilateral movement and precise calibration of the quadrilateral structure composed of the wall support mechanism 1 and the calibration mechanism 2.

[0057] Figure 1-Figure 4 , Fig.10 and Fig.11 As shown, in some embodiments, the guide rail measuring mechanism 3 includes a slide rail 31 installed on the embracing frame 244 of the clamping assembly 24, an X-axis distance measuring sensor 33 and a Y-axis distance measuring sensor 34 slidably connected to one end of the slide rail 31, an auxiliary deflection measurement sensor 37 slidably connected to the other end of the slide rail 31, and an end identifier 32, a magnetic block 35 and a locking block 36 connected to the slide rail 31 and connected to each other; the guide rail measuring mechanism 3 is adsorbed on the elevator guide rail 8 through the magnetic block 35 and clamped by the locking block 36, the X-axis distance measuring sensor 33 and the Y-axis distance measuring sensor 34 calibrate and adjust the accuracy of the elevator guide rail 8 by measuring the distance of the sample line 7; the auxiliary deflection measurement sensor 37 is used to measure the deflection size of the elevator guide rail 8 to recalibrate the accuracy of the elevator guide rail 8; the end identifier 32 is used to identify the ring beam structure of the elevator shaft.

[0058] Furthermore, there are two guide rail measuring mechanisms 3, which are respectively located on the clamping assemblies 24 of the two calibration mechanisms 2, and are respectively used to measure and calibrate the installation accuracy of the two elevator guide rails in the elevator hoistway.

[0059] In this embodiment, the guide rail measuring mechanism 3 is installed on the clamping assembly 24, and the elevator guide rail 8 is used to assist in positioning. By adjusting the distance, the sample line 7 is ensured to be within the measurement range of the X-axis distance sensor 33 and the Y-axis distance sensor 34, so as to avoid repeated disassembly of the guide rail measuring mechanism 3. Among them, the sample line 7 moves within the limited space of the guide rail measuring mechanism 3, and the offset direction can be clearly determined even if it exceeds the measurement range. When automatically adjusting the elevator guide rail 8, according to the calibration accuracy of the X-axis distance sensor 33 and the Y-axis distance sensor 34, the auxiliary deflection measurement sensor 37 ensures that the deflection of the elevator guide rails 8 on both sides is adjusted to the same straight line to ensure the parallelism of the elevator guide rails 8.
