Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of elevators, and particularly to a guide rail frame for installing an escalator. Background Art
[0002] An escalator, or an automatic pedestrian elevator, handrail elevator, moving staircase, is a type of escalator with a circulating running staircase, and is a fixed power-driven device for transporting passengers upward or downward on an inclined path. An escalator is generally inclined. When a pedestrian stands on the automatically moving steps at one end of the escalator, they will be automatically taken to the other end. During the journey, the steps will remain horizontal all the way. Handrails that move synchronously with the steps are provided on both sides of the escalator for users to hold. An escalator can always run in one direction, but most can be controlled by the management staff to change the running direction according to time, the flow of people, etc. Another pedestrian transportation tool very similar to an escalator is an automatic walkway. The main difference between the two is that an automatic walkway has no steps and mostly runs on flat ground or with a slight inclination.
[0003] The escalator step track guide rail includes all the guide rails for the main and auxiliary wheels, the return rail and the corresponding supports. The step track is a closed loop system, which is divided into an upper step track system, a lower step track system, a traction chain, and a rotating wall part. The function of the escalator guide rail system is to ensure that the steps follow a predetermined trajectory. When installing the step chain, the step chain rollers need to be clamped inside the guide rail, and the guide rail positions the step chain rollers to achieve the positioning of the step chain. When the step chain rollers are running, the rollers at both ends of the step chain need to be absolutely parallel. However, in common step chain rollers at present, they are often directly clamped inside the guide rail, and there is a gap between the inner wall of the guide rail and the rollers. As the use time increases, the clearance between the rollers and the inner wall of the guide rail increases, resulting in the step chain being prone to shaking during operation. In addition, when the escalator is running, the maximum tension on the step chain is generally located at the upper and lower corner positions of the escalator, that is, the R section commonly known in the industry. During operation, the R section needs to bear the impact of the step chain's own operation and the load of passengers. After long-term use, it is easy to cause the R section to be deformed by the force. For this reason, we propose a guide rail frame for installing an escalator to solve the above-mentioned problems. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the present invention provides a guide rail frame for installing an escalator, which has the advantages of reducing the stress level of the R section of the escalator and improving the stability of the step chain rollers during operation, and solves the problems raised in the above background art.
[0005] To achieve the above objectives of reducing the stress on the R section of the escalator and improving the stability of the step chain rollers during operation, the present invention is realized through the following technical solutions: A guide rail frame for installing an escalator includes two sets of guide rail frames. Inside each of the two sets of guide rail frames, there is a fixedly connected mounting frame. The guide rail frame includes a linear conveying mechanism, an upper R section mechanism, a lower R section mechanism, and a swivel head mechanism. Inside each of the two sets of guide rail frames, there are detachably and fixedly installed a first connecting ring and a second connecting ring. On the inner sides of the first connecting ring and the second connecting ring, there are positioning strips. Inside the positioning strips, there are embedded third pressure sensors. Inside each of the two sets of guide rail frames, there is a clamped step chain roller, and a connecting rod is fixedly connected to the middle of the step chain roller. On the mounting frame, there are a first pressure sensor, a second pressure sensor, a first electric telescopic rod, and a second electric telescopic rod located at the upper R section mechanism and the lower R section mechanism. On the circumferential side of the step chain roller, there are positioning grooves that cooperate with the positioning strips. The step chain roller is clamped inside the guide rail frame through the positioning strips and the positioning grooves. Inside the positioning strips, there are evenly distributed third pressure sensors, and the number of the third pressure sensors is at least three. The distance from the end of the third pressure sensor to the surface of the positioning strip is 0.2 - 0.5 mm. At both ends of the guide rail frame, there are swivel head mechanisms. At the connection parts between the guide rail frame and the two swivel head mechanisms, there are respectively an upper R section mechanism and a lower R section mechanism. On the mounting frame, there are support frames located at the upper R section mechanism and the lower R section mechanism, and a first electric telescopic rod is fixedly installed inside the support frames. A first top plate is fixedly connected to the output shaft of the first electric telescopic rod. On the mounting frame, there is a second electric telescopic rod located at the upper R section mechanism and the lower R section mechanism, and a second top plate is fixedly connected to the output shaft of the second electric telescopic rod.
[0006] Preferably, on the mounting frame, there is a first pressure sensor located at the upper R section mechanism and the lower R section mechanism, and a second pressure sensor is fixedly installed on the support frame.
[0007] Preferably, the positioning strips are located in the middle of the front and rear sides of the first connecting ring and the second connecting ring, and the width values of the first connecting ring and the second connecting ring are the same as the depth values inside the guide rail frame.
[0008] The present invention provides a guide rail frame for installing an escalator, which has the following beneficial effects:
[0009] 1. For the guide rail frame of the escalator installation, by arranging first pressure sensors on the inner and outer sides of the R sections on the upper and lower sides of the guide rail frame, when in operation, the force-bearing degree of the R sections of the guide rail frame is detected by the first pressure sensors, and the detection signals are fed back to the control system of the escalator. The control system controls the first electric telescopic rod and the second electric telescopic rod to drive the first top plate and the second top plate to press against the guide rail frame respectively according to the signals detected by the first pressure sensors, balancing the force on the R sections of the guide rail frame during the operation of the escalator, preventing excessive unidirectional force on the R sections from causing damage, and improving the service life.
[0010] 2. For the guide rail frame of the escalator installation, by fixedly installing a first connecting ring and a second connecting ring inside the guide rail frame, positioning is carried out through the positioning strips on the inner sides of the first connecting ring and the second connecting ring in combination with the positioning grooves outside the step chain rollers, ensuring the stability of the step chain rollers during operation, improving the stability of the step chain during operation, and reducing the probability of faults occurring during the operation of the escalator.
[0011] 3. For the guide rail frame of the escalator installation, by inlaying third pressure sensors in the positioning strips on the inner sides of the first connecting ring and the second connecting ring, when the positioning strips are worn, the third pressure sensors can come into contact with the running step chain rollers, so that the third pressure sensors are subjected to pressure and the signals are fed back to the control system, enabling the detection of the wear degree of the positioning strips and allowing for timely replacement of the positioning strips to ensure the accuracy of the positioning of the step chain rollers by the positioning strips.

Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0020] Please refer to Figure 1 , the present invention provides a technical solution: a guide rail frame for installing an escalator, including two groups of guide rail frames 1. Inside both groups of guide rail frames 1, there are fixedly connected mounting frames 2. The guide rail frame 1 includes a linear conveying mechanism 4, an upper R-section mechanism 5, a lower R-section mechanism 6, and a slewing head mechanism 3. Inside both groups of guide rail frames 1, there are detachably and fixedly installed a first connection ring 16 and a second connection ring 17. Inside the first connection ring 16 and the second connection ring 17, there are positioning strips 18. The step chain roller 8 is positioned by the positioning strip 18, which ensures the stability of the step chain roller 8 during operation and improves the stability of the step chain during operation. Inside the positioning strip 18, there is inlaid a third pressure sensor 19. The third pressure sensor 19 can detect the wear condition of the positioning strip 18, and the positioning strip 18 can be replaced in time to ensure the accuracy of the positioning of the step chain roller 8 by the positioning strip 18. Inside both groups of guide rail frames 1, there is a snap connection of step chain rollers 8, and a connecting rod 7 is fixedly connected to the middle of the step chain roller 8. On the mounting frame 2, there are a first pressure sensor 9, a second pressure sensor 15, a first electric telescopic rod 11, and a second electric telescopic rod 13 located at the upper R-section mechanism 5 and the lower R-section mechanism 6. When the escalator is running, the force condition of the R-section of the escalator can be detected by combining the first pressure sensor 9 and the second pressure sensor 15. The first electric telescopic rod 11 drives the first top plate 12 to move, and the second electric telescopic rod 13 drives the second top plate 14 to move, applying a top pressure to the guide rail frame 1 to balance the force on the R-section of the guide rail frame 1 during the operation of the escalator.
[0021] Please refer to Figure 2 , at both ends of the guide rail frame 1, there are slewing head mechanisms 3. At the connection parts of the guide rail frame 1 and the two groups of slewing head mechanisms 3, there are respectively an upper R-section mechanism 5 and a lower R-section mechanism 6. By setting the slewing head mechanism 3 and the upper R-section mechanism 5 and the lower R-section mechanism 6, the guide rail frame can form a circular whole, thereby restricting the running direction of the step chain and ensuring the stability of the step chain during operation.
[0022] Please refer to Figure 3 As shown in the figure, a support frame 10 is fixedly installed on the mounting frame 2 at the upper R-section mechanism 5 and the lower R-section mechanism 6. A first electric telescopic rod 11 is fixedly installed inside the support frame 10, and a first top plate 12 is fixedly connected to the output shaft of the first electric telescopic rod 11. A second electric telescopic rod 13 is fixedly installed on the mounting frame 2 at the upper R-section mechanism 5 and the lower R-section mechanism 6, and a second top plate 14 is fixedly connected to the output shaft of the second electric telescopic rod 13. The control system controls the first electric telescopic rod 11 and the second electric telescopic rod 13 to drive the first top plate 12 and the second top plate 14 to press against the guide rail frame 1 respectively according to the signal detected by the first pressure sensor 9, so as to balance the force on the R-section of the guide rail frame 1 during the operation of the escalator.
[0023] Please refer to Figure 1 As shown in the figure, a first pressure sensor 9 is arranged on the mounting frame 2 at the upper R-section mechanism 5 and the lower R-section mechanism 6, and a second pressure sensor 15 is fixedly installed on the support frame 10. When the escalator is running, the force conditions of the upper R-section mechanism 5 and the lower R-section mechanism 6 are detected by the first pressure sensor 9 and the second pressure sensor 15 and fed back to the control system, which is convenient for subsequent balancing of the forces on the upper R-section mechanism 5 and the lower R-section mechanism 6.
[0024] Please refer to Figure 5 and 6 As shown in the figure, a positioning groove 20 that cooperates with the positioning strip 18 is formed on the circumferential side of the step chain roller 8. The step chain roller 8 is clamped inside the guide rail frame 1 through the positioning strip 18 and the positioning groove 20, which ensures the stability of the step chain roller 8 during operation, improves the stability of the step chain during operation, and reduces the probability of faults occurring during the operation of the escalator.
[0025] Please refer to Figure 4 As shown in the figure, evenly distributed third pressure sensors 19 are embedded inside the positioning strip 18, and the number of the third pressure sensors 19 is at least three groups. When the positioning strip 18 is worn, the third pressure sensors 19 can contact the running step chain roller 8, so that the third pressure sensors 19 are stressed and the signals are fed back to the control system, and the wear degree of the positioning strip 18 can be detected.
[0026] The distance from the end of the third pressure sensor 19 to the surface of the positioning strip 18 is 0.2 - 0.5 mm, reserving a wear value of 0.2 - 0.5 mm for the positioning strip 18. When the positioning strip 18 is gradually worn, the third pressure sensor 19 can contact the step chain roller 8 for detection.
[0027] The positioning strip 18 is located in the middle of the front and rear sides of the first connecting ring 16 and the second connecting ring 17, ensuring the balanced force on the front and rear sides of the step chain roller 8 during operation, and further improving the stability of the step chain roller 8 during operation.
[0028] The width values of the first connecting ring 16 and the second connecting ring 17 are the same as the depth value inside the guide rail frame 1. The first connecting ring 16 and the second connecting ring 17 can be installed inside the guide rail frame 1 by screws, facilitating the replacement of the positioning strip 18 through the first connecting ring 16 and the second connecting ring 17.
[0029] In summary, for the guide rail frame of this installed escalator, during use, when the escalator is running, the first pressure sensor 9 and the second pressure sensor 15 on the inner and outer sides of the upper R-section mechanism 5 and the lower R-section mechanism 6 detect the stress level of the R-section of the guide rail frame 1 during operation, and feedback the detection signal to the control system of the escalator. The control system controls the first electric telescopic rod 11 to drive the first top plate 12 to move and the second electric telescopic rod 13 to drive the second top plate 14 to move according to the signals detected by the first pressure sensor 9 and the second pressure sensor 15, applying an upward pressure to the guide rail frame 1 to balance the stress of the R-section of the guide rail frame 1 during escalator operation. When the step chain is running, the positioning strip 18 inside the first connecting ring 16 and the second connecting ring 17 and the third pressure sensor 19 outside the step chain roller 8 are used to position the step chain roller 8, ensuring that the step chain rollers 8 at both ends of the step chain are absolutely parallel, guaranteeing the stability of the step chain during operation. The third pressure sensor 19 inside the first connecting ring 16 and the second connecting ring 17 detects the wear degree of the positioning strip 18 and feeds the signal back to the control system to detect the wear degree of the positioning strip 18. When the positioning strip 18 is worn excessively, the positioning strip 18 can be replaced in a timely manner.
