Description

Technical Field

[0001] The present invention relates to the technical field of elevator installation and construction, and in particular to a leveling-adjustable wall supporting mechanism and an adjustment method thereof. Background Art

[0002] With the development of the economy and society, high-rise buildings are increasing in number. Elevators in these buildings have become an indispensable part of people's lives, and elevator installation equipment is becoming increasingly sophisticated. Currently, elevator installation equipment is developing towards intelligent, automated, and unmanned operation. Various drilling and calibration robots are gradually transitioning from concept to reality. While these robots are operating, they need to be secured by a wall support mechanism before they can continue to operate other functions. However, if the wall support mechanism tilts during wall support, the entire system will tilt, affecting subsequent operations such as drilling and calibration accuracy, potentially preventing some functions from functioning properly, and thus affecting the normal use of the elevator. Therefore, leveling the wall support mechanism is crucial for elevator installation.

[0003] At present, most wall-supporting mechanisms adopt a direct wall-supporting method to abut against the elevator shaft. They cannot adjust themselves and are difficult to deal with walls that are too tilted or uneven. When adjusting the wall-supporting mechanism, each support point of the wall-supporting mechanism is usually adjusted one by one by manually operating mechanical components such as screws, nuts, and jacks to change the height or angle of the support position so that the wall-supporting mechanism reaches a horizontal state. However, this method has limited leveling accuracy and low leveling efficiency, which can easily lead to deviations in the verticality and parallelism of the track, affecting the stability and accuracy of the elevator operation. The Chinese patent document with publication number CN113800358A provides a rigid and flexible wall-supporting mechanism for an elevator shaft. Although it is equipped with a horizontal posture detection component and a vertical posture detection component, and can adjust the horizontal and vertical directions of the wall-supporting mechanism, it relies on four sets of mechanical arms for wall support and adjustment. The overall structure is relatively complex and the size is large. Moreover, the extension and retraction are all done by hydraulic rods or electric push rods, which has limited applicability to shafts of different sizes. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a leveling wall support mechanism and an adjustment method thereof, which solves the problems in the prior art that the manual adjustment accuracy of the wall support mechanism is limited and the leveling efficiency is low, resulting in deviations in the verticality and parallelism of the track, and when a mechanical arm is used for wall support adjustment, the structure is complex, the size is large, and the applicability to wells of different sizes is limited.

[0005] In a first aspect, the present invention provides a leveling wall support mechanism, comprising:

[0006] main beam;

[0007] a telescopic module connected to the main beam;

[0008] A secondary beam, the secondary beam being connected to a side of the main beam facing away from the telescopic module;

[0009] a first leveling module connected to the telescopic module;

[0010] a second leveling module connected to the sub-beam;

[0011] A sensor and a control system, wherein the sensor and the control system are mounted on the main beam, and the sensor is connected to the control system;

[0012] The sensor can detect the inclination angle of the wall support mechanism and transmit the detection information to the control system. According to the detection information, the control system controls the first leveling module to move in the vertical direction and controls the second leveling module to rotate in the horizontal direction to achieve leveling of the wall support mechanism.

[0013] In one embodiment of the present invention, the first leveling module includes a first driving mechanism, a first screw rod and a first slider. The first driving mechanism is connected to the first screw rod, and the first screw rod is slidingly connected to the first slider. The control system can control the movement of the first driving mechanism.

[0014] In one embodiment of the present invention, the first leveling module further includes a first beam, a first rotating shaft, a mounting plate, and an elastic body. The first beam is hingedly connected to the first slider via the first rotating shaft, the mounting plate abuts against the first beam, and the elastic body abuts against the mounting plate. This ensures that the first beam remains horizontal in the initial state and can return to a horizontal state after supporting the wall.

[0015] In one embodiment of the present invention, the second leveling module includes a push rod, a second cross beam and a base, the base is connected to the sub-beam, the push rod is connected to the base, the second cross beam is connected to the push rod and the base respectively, and the push rod, the second cross beam and the base form a triangular structure.

[0016] In one embodiment of the present invention, the second leveling module also includes a third driving mechanism, a second rotating shaft and a third rotating shaft. The third driving mechanism is connected to the push rod and can drive the push rod to perform telescopic movement; the push rod is hinged to the second beam through the second rotating shaft, and the second beam is hinged to the base through the third rotating shaft. The control system can control the movement of the third driving mechanism.

[0017] In one embodiment of the present invention, a pin is provided on the main beam, and the pin extends through the through holes of the telescopic module, the main beam, and the auxiliary beam, thereby connecting the telescopic module and the auxiliary beam to the main beam. By changing the position of the connecting holes, the initial length of the wall support mechanism can be adjusted, making it suitable for elevator shafts of different sizes, thereby increasing the applicability of the mechanism.

[0018] In one embodiment of the present invention, the telescopic module includes a second lead screw, a second slider, a telescopic seat and a telescopic sub-beam, the second slider is mounted on the outer periphery of the second lead screw and can move along the second lead screw; the telescopic seat is connected to the main beam, the telescopic sub-beam is connected to the second slider, and the first leveling module is installed on the telescopic sub-beam.

[0019] In one embodiment of the present invention, the telescopic module further includes a second driving mechanism and a screw seat, the screw seat is connected to the telescopic seat, and the second driving mechanism passes through the screw seat and is connected to the second screw;

[0020] The telescopic seat is provided with a hole, and the pin shaft passes through the hole to connect the telescopic seat with the main beam.

[0021] In one embodiment of the present invention, a ratchet block and a distance sensor are installed on both the first crossbeam and the second crossbeam, a first brake pad is installed on the first drive mechanism, and a second brake pad is installed on the second drive mechanism, and the sensor is an angle sensor. The first brake pad and the second brake pad perform a braking action in the event of a power outage to ensure that the state of the wall support does not change. If the brake pads are not used, the motor may rotate under its own weight, thereby losing its original horizontal state. The distance sensor can detect the distance between the two ends of the beam and the wall and compare it with a preset value to determine whether the wall has a large tilt, unevenness, foreign objects, etc., to avoid failure of the wall support mechanism due to the above conditions.

[0022] In a second aspect, the present invention provides a method for adjusting a leveling wall support mechanism, the method comprising:

[0023] Step 1: Install the wall support mechanism in the elevator shaft, adjust the relative positions of the telescopic module, auxiliary beam and main beam, and then use pins to connect the telescopic module, auxiliary beam and main beam;

[0024] Step 2: At a specified height, the distance sensors at both ends of the first beam detect the distances from the wall and calculate the difference between the two. This difference is compared with a preset value. If it exceeds the preset value, the position of the wall support is adjusted until the difference between the two does not exceed the preset value. The distance sensors at both ends of the second beam detect the distances from the other wall and calculate the difference between the two. This difference is compared with a preset value. If it exceeds the preset value, the position of the wall support is adjusted until the difference between the two does not exceed the preset value.

[0025] Step 3: The control system drives the second driving mechanism to rotate, so that the telescopic sub-beam of the telescopic module is gradually extended until the first crossbeam and the second crossbeam respectively abut against the wall of the shaft and maintain a certain pressure on the wall;

[0026] Step 4. Horizontal leveling: The sensor reads the horizontal tilt angle in the current state and transmits it to the control system. The control system controls the third drive mechanism to perform forward or reverse motion according to the angle value, so that the push rod extends or retracts, driving the base to rotate around the third rotation axis, thereby driving the main beam, telescopic module and auxiliary beam to rotate, so as to achieve horizontal angle adjustment of the main beam, telescopic module and auxiliary beam. The horizontal tilt angle read by the sensor in real time is compared with the value 0 until the difference between the horizontal tilt angle and the value 0 is less than the preset value.

[0027] Step 5, vertical leveling: The sensor reads the vertical tilt angle in the current state and transmits it to the control system. The control system controls the first drive mechanism to drive the first screw rod to rotate forward or reverse according to the angle value, so that the first screw rod moves relative to the first slider, thereby changing the height of the telescopic sub-beam close to the first leveling module. The sensor reads the vertical tilt angle in real time and compares it with the value of 0 until the difference between the vertical tilt angle and the value of 0 is less than a preset value.

[0028] Step 6. Horizontal angle re-detection: The sensor reads the horizontal tilt angle in the current state and confirms whether the difference between the horizontal tilt angle and 0 is less than a preset value. If it is less than the preset value, it means that the wall support mechanism has been leveled and the adjustment is completed. Otherwise, repeat Step 4.

[0029] Step 7: The control system drives the second driving mechanism to rotate, so that the telescopic sub-beam of the telescopic module extends again until the pressure on the wall reaches the required wall-supporting value.

[0030] Beneficial effects of the present invention:

[0031] The present invention provides a leveling wall support mechanism comprising a first leveling module, a second leveling module, an angle sensor, and a control system. The angle sensor detects the horizontal and vertical tilt angles of the main beam and transmits this information to the control system, which drives the first and second leveling modules to achieve automatic leveling of the wall support mechanism. This fully automated operation eliminates the need for human intervention, improving the wall support mechanism's leveling accuracy and efficiency, preventing tilting of the wall support mechanism and the resulting equipment, and ensuring the normal operation of the elevator.

[0032] 2. The main beam of this leveling wall support mechanism is equipped with several through-holes, through which pins pass to connect the telescopic module and the secondary beam to the main beam. By adjusting the position of the connecting holes, the initial length of the wall support mechanism can be adjusted, adapting it to elevator shafts of varying sizes and expanding its applicability. Driven by a second drive mechanism, the telescopic module can be extended and retracted, ensuring that the wall support mechanism exerts the required pressure on the wall.

[0033] 3. The first and second beams of this leveling wall support mechanism are equipped with ratchet blocks on both sides. These blocks abut the shaft wall, transferring the pressure provided by the telescopic module to the wall, converting it into sufficient friction to secure the first and second beams to the shaft wall. The first and second beams are hingedly connected to the telescopic module and auxiliary beam, respectively, allowing for rotation within a certain range, making them suitable for tilted and uneven walls.

[0034] 4. Distance sensors are installed on both sides of the first and second beams of the leveling wall support mechanism. The distance sensors can detect the distance between the two ends of the beam and the wall and compare it with the preset value to determine whether the wall has a large tilt, unevenness, foreign objects, etc., to avoid failure of the wall support mechanism due to the above conditions.

Those skilled in the art will understand the specific meanings of the above terms in the present invention.

[0046] like Figures 1 to 6 As shown, the present invention provides a leveling wall support mechanism. After the wall support mechanism is installed in the hoistway, the wall support mechanism can automatically and quickly level itself to prevent the equipment from tilting and ensure the smooth operation of the elevator. The leveling wall support mechanism includes a first leveling module 1, a telescopic module 2, a main beam 3, a sensor 4, a control system 5, a pin 6, a sub-beam 7, and a second leveling module 8. One end of the telescopic module 2 is connected to the first leveling module 1, and the end of the telescopic module 2 facing away from the first leveling module 1 is installed in the main beam 3. One end of the sub-beam 7 is set in the main beam 3, and the end of the sub-beam 7 facing away from the main beam 3 is connected to the second leveling module 8. The sensor 4 and the control system 5 are both installed on the main beam 3. The sensor 4 is connected to the control system 5. The sensor 4 is an angle sensor used to monitor the vertical and horizontal angles of the wall support mechanism and can feed back the monitored data to the control system 5. The control system 5 automatically adjusts the wall support mechanism by controlling the first leveling module 1 and the second leveling module 8 to make the wall support mechanism reach a horizontal state.

[0047] In some embodiments, a plurality of through holes 31 are provided on the main beam 3, and the pin shaft 6 passes through the through holes 31 on the telescopic module 2, the auxiliary beam 7 and the main beam 3, so that the telescopic module 2 and the auxiliary beam 7 are connected to the main beam 3. By changing the different hole positions of their connection, the initial length of the wall support mechanism can be adjusted so that it can be suitable for elevator shafts of different sizes, thereby improving the scope of application of this mechanism.

[0048] In some embodiments, the first leveling module 1 includes a bracket 110, a first driving mechanism 17, a first screw rod 18, a guide rail 16 and a first slider 15. The first leveling module 1 is mounted on the telescopic module 2 via the bracket 110, and the first driving mechanism 17 is connected to the control system 5, which can control the start or stop of the first driving mechanism 17. The first driving mechanism 17 is connected to the first screw rod 18, which is mounted on the guide rail 16, which is mounted on the bracket 110. The first screw rod 18 is slidably connected to the first slider 15, and the first screw rod 18 can slide relative to the first slider 15 under the drive of the first driving mechanism 17. A first crossbeam 14 is installed on the side of the first slider 15 facing away from the first screw rod 18. The first crossbeam 14 is connected to the first slider 15 via the first rotating shaft 13, and the first crossbeam 14 is hinged to the first rotating shaft 13. When the first crossbeam 14 contacts the shaft wall, the first drive mechanism 17 drives the first lead screw 18 to move vertically along the first slider 15. This, in turn, drives the end of the telescopic module 2 closest to the first leveling module 1 to move vertically, thereby maintaining the telescopic module 2, main beam 3, and auxiliary beam 7 in a horizontal position. In the initial state, the first slider 15 is positioned midway between the first lead screw 18, enabling the telescopic module 2 to reciprocate vertically, adjusting the vertical tilt angle of the wall support mechanism.

[0049] In some embodiments, an elastic body 11 and a mounting plate 12 are installed below the first crossbeam 14. There are two mounting plates 12, namely a first mounting plate 121 and a second mounting plate 122. The first crossbeam 14 is symmetrically mounted above the first mounting plate 121. The first mounting plate 121 abuts the first crossbeam 14, and the second mounting plate 122 is fixedly connected to the first slider 15. The first mounting plate 121 and the second mounting plate 122 are connected by bolts. The two ends of the elastic body 11 abut the first mounting plate 121 and the second mounting plate 122 respectively. There are also two elastic bodies 11, symmetrically arranged between the two mounting plates 12, which can ensure that the first crossbeam 14 remains horizontal in the initial state and can return to a horizontal state after the wall support is completed.

[0050] In some embodiments, the second leveling module 8 includes a third drive mechanism 81, a push rod 82, a second rotating shaft 83, a third rotating shaft 84, a second crossbeam 85, and a base 86. The base 86 is connected to the sub-beam 7. The third drive mechanism 81 is connected to the push rod 82. The end of the push rod 82 facing away from the third drive mechanism 81 is connected to the second crossbeam 85. The push rod 82 is hinged to the second crossbeam 85 via the second rotating shaft 83, and the second crossbeam 85 is hinged to the base 86 via the third rotating shaft 84. The third drive mechanism 81 and the push rod 82 are connected to the base 86 via a mounting bracket. The push rod 82, the second crossbeam 85, and the base 86 form a triangular structure. The third drive mechanism 81 is connected to the control system 5, which can control the start and stop of the third drive mechanism 81. The third drive mechanism 81 drives the push rod 82 in reciprocating motion. Extending or retracting the push rod 82 changes the angle between the second crossbeam 85 and the base 86, causing the base 86 to rotate about the third rotation axis 84, thereby rotating the main beam 3, the telescopic module 2, and the auxiliary beam 7. This adjusts the horizontal angle of the main beam 3, the telescopic module 2, and the auxiliary beam 7, thereby bringing them to a horizontal position. Initially, the push rod 82 is mid-stroke, facilitating increasing or decreasing the angle between the second crossbeam 85 and the base 86.

[0051] In some embodiments, the telescopic module 2 includes a second drive mechanism 21, a second slider 22, a second screw rod 23, a telescopic base 24, a telescopic sub-beam 25, and a screw rod base 26. The telescopic base 24 is provided with a hole 27, through which the pin 6 passes to connect the telescopic base 24 to the main beam 3. The screw rod base 26 is fixedly mounted on the telescopic base 24. One end of the screw rod base 26 is connected to the second drive mechanism 21. The second screw rod 23 is connected to the output end of the second drive mechanism 21. The second slider 22 is sleeved on the outer periphery of the second screw rod 23 and is capable of moving along the second screw rod 23. The second slider 22 is fixedly connected to the telescopic sub-beam 25, and the end of the telescopic sub-beam 25 facing away from the second slider 22 is connected to the bracket 110. The second drive mechanism 21 is connected to the control system 5, which can control the start or stop of the second drive mechanism 21. The second driving mechanism 21 drives the second screw rod 23 to rotate, so that the second slider 22 moves along the second screw rod 23, thereby driving the telescopic sub-beam 25 to move along the second screw rod 23, realizing the telescopic module 2. It can be used for the telescopic adjustment of the wall supporting mechanism in the length direction, so that the pressure of the wall supporting mechanism on the wall reaches the required wall supporting value.

[0052] In some embodiments, ratchet blocks 19 are mounted on both the first crossbeam 14 and the second crossbeam 85. These ratchet blocks 19 can abut against the shaft wall, securing the first and second crossbeams 14, 85 to the shaft wall. The ratchet blocks 19 are positioned on either side of the first crossbeam 14 to transfer the pressure provided by the telescopic module 2 to the wall, converting it into sufficient friction against the wall.

[0053] In some embodiments, a distance sensor 9 is provided on the first beam 14 and the second beam 85 respectively. The distance sensor 9 can detect the distance between the two ends of the beam and the wall and compare it with the preset value, so as to determine whether the wall has a large tilt, unevenness, foreign objects, etc., to avoid the failure of the wall support mechanism due to the above conditions.

[0054] Optionally, a first brake pad 171 is installed on the first drive mechanism 17, and a second brake pad 811 is installed on the second drive mechanism 81. The first brake pad 171 and the second brake pad 811 perform braking in the event of a power outage, thereby ensuring that the wall support state remains unchanged. If the brake pads are not used, the motor may rotate under its own weight, thereby losing its original horizontal state.

[0055] Optionally, the first drive mechanism 17, the second drive mechanism 21, and the third drive mechanism 81 all use motors and are connected to the control system 5. The sensor 4 monitors the vertical and horizontal angles of the main beam 3 in real time and transmits the monitoring data to the control system 5. The control system 5 controls the first drive mechanism 17 and the third drive mechanism 81 to adjust the main beam 3 to a horizontal state.

[0056] Optionally, two sensors 4 may be provided, both mounted on the main beam 3 and connected to the control system 5. The two sensors 4 are used to monitor the horizontal tilt angle and the vertical tilt angle, respectively, and feed the monitored data back to the control system 5. The control system 5 simultaneously controls the movement of the first drive mechanism 11 and the third drive mechanism 81, so that the wall support mechanism can simultaneously adjust the horizontal tilt angle and the vertical tilt angle until the value detected by the sensor 4 is 0. This can improve the adjustment efficiency of the wall support mechanism.

[0057] Optionally, other sensors can be installed on the main beam 3 and combined with the data detected by the sensor 4 to avoid failure of a single sensor or errors in the detection data, which prevents the wall support mechanism from being adjusted to a horizontal state.

[0058] Optionally, the elastic body 11 is a spring. Two springs are symmetrically installed between the two mounting plates 12 to keep the first crossbeam 14 horizontal.

[0059] In addition, the present invention also provides an adjustment method for a leveling wall support mechanism:

[0060] Step 1. Install the wall support equipment in the elevator shaft, adjust the relative positions of the telescopic module 2, the auxiliary beam 7 and the main beam 3, and then use the pin 6 to fix the telescopic module 2, the auxiliary beam 7 and the main beam 3.

[0061] Step 2. At the specified height, the distance sensors 9 at both ends of the first beam 14 respectively detect the distance between the two ends and the wall, and calculate the difference between the two. By comparing the difference with the preset value, if it exceeds the preset value, it means that the inclination angle and the unevenness of the wall are too large, and the position of the supporting wall needs to be adjusted; after adjustment, re-detection is performed until the difference between the two does not exceed the preset value; then, the distance sensors 9 at both ends of the second beam 85 respectively detect the distance between the two ends and the other side wall, and calculate the difference between the two. By comparing the difference with the preset value, if it exceeds the preset value, it means that the inclination angle and the unevenness of the wall are too large, and the position of the supporting wall needs to be adjusted; after adjustment, re-detection is performed until the difference between the two does not exceed the preset value.

[0062] Step 3: The control system 5 drives the second driving mechanism 21 to rotate, so that the telescopic sub-beam 25 of the telescopic module 2 is gradually extended until the first crossbeam 14 and the second crossbeam 85 respectively abut against the wall and maintain a certain pressure on the wall.

[0063] Step 4, horizontal leveling: The sensor 4 reads the horizontal tilt angle in the current state and transmits it to the control system 5. The control system 5 controls the third drive mechanism 81 to rotate forward or reverse according to the angle value, so that the push rod 82 extends or retracts, driving the base 86 to rotate around the third rotation axis 84, thereby driving the main beam 3, the telescopic module 2 and the auxiliary beam 7 to rotate, and realizing the horizontal angle adjustment of the main beam 3, the telescopic module 2 and the auxiliary beam 7. Since the first beam 14 and the second beam 85 are provided with a ratchet block 19, the friction between the ratchet block 19 and the wall is significantly greater than the friction at the hinge between the base 86 and the third rotation axis 84, so that the wall-supporting mechanism itself can rotate; the horizontal tilt angle read in real time by the sensor 4 is compared with the value 0 until the difference between the horizontal tilt angle and the value 0 is less than the preset value.

[0064] Step 5, vertical leveling: The sensor 4 reads the vertical tilt angle in the current state and transmits it to the control system 5. The control system 5 controls the first drive mechanism 17 to drive the first screw rod 18 to rotate forward or reverse according to the angle value, so that the first screw rod 18 moves upward or downward, thereby changing the height of the end of the telescopic sub-beam 2; the vertical tilt angle read by the sensor 4 in real time is compared with the value 0 until the difference between the vertical tilt angle and the value 0 is less than the preset value.

[0065] Step 6. Horizontal angle re-detection: Sensor 4 reads the horizontal tilt angle in the current state and confirms whether the difference between the horizontal tilt angle and 0 is less than the preset value. If it is less than the preset value, it means that the wall support mechanism has been leveled and the adjustment is completed. Otherwise, repeat Step 4.

[0066] Step 7: The control system 5 drives the second driving mechanism 21 to rotate, so that the telescopic sub-beam 25 of the telescopic module 2 is extended again until the pressure on the wall reaches the required wall-supporting value.

[0067] The wall support mechanism automatically reads the horizontal and vertical tilt angles and controls different modules for automated adjustment. This fully automated operation eliminates the need for human intervention, improving the leveling accuracy and efficiency of the wall support mechanism and preventing tilting of the wall support mechanism, which could cause equipment tilt and affect the normal operation of the elevator. Furthermore, by changing the perforation position of the pin 6 on the main beam 3, the spacing between the main beam 3, the telescopic module 2, and the secondary beam 7 can be manually adjusted, expanding its applicability to a wide range of hoistway sizes.
