Description

Technical Field

[0001] This utility model relates to the field of straightening device technology, specifically an elevator guide rail straightening device. Background Technology

[0002] An elevator guide rail straightening device is a specialized piece of equipment used to correct problems such as bending, twisting, and unevenness in elevator guide rails. This device effectively improves the straightness and flatness of the elevator guide rails, thereby ensuring stable elevator operation and passenger safety. Therefore, the guide rails need to be straightened before installation, requiring the use of an elevator guide rail straightening device.

[0003] Existing guide rail straightening devices generally use two sets of staggered pressing rollers to straighten the bent parts of the guide rail. However, since the distance between the two sets of pressing rollers is relatively fixed, it is inconvenient to straighten guide rails of different widths, making it inconvenient to use.

[0004] Furthermore, when the guide rail is straightened using only the compression roller, the compression force on the guide rail is limited, making it difficult to apply appropriate compression force to the degree of bending of the guide rail, resulting in an unsatisfactory straightening effect. Therefore, it is necessary to propose an elevator guide rail straightening device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an elevator guide rail straightening device, which has the characteristics of adjustable distance between the extrusion rollers, convenient for straightening guide rails of different widths, and can apply corresponding extrusion force according to the degree of curvature of the guide rail, resulting in good straightening effect.

[0006] The purpose of this utility model is to provide an elevator guide rail straightening device, including a U-shaped frame. The U-shaped frame is rotatably connected to a reverse threaded screw. The outer wall of the reverse threaded screw is threaded with two symmetrically distributed threaded sleeves. The upper end face of each of the two threaded sleeves is fixedly connected to a support plate. The upper end face of each of the two support plates is fixedly connected to a mounting plate. An electric push rod is installed on the opposite side of each of the two mounting plates. The output end of each of the two electric push rods passes through the mounting plate and is fixedly connected to a pressing plate.

[0007] Multiple evenly distributed extrusion rollers are rotatably connected to the upper end faces of both support plates;

[0008] Each of the two support plates has a mounting shell fixedly connected to its upper end face. Each of the two mounting shells has a lidar sensor installed inside. The opposite sides of the two lidar sensors are flush with the two support plates respectively.

[0009] To facilitate the movement of the drive rail, in a preferred embodiment of the elevator guide rail straightening device of this utility model, the upper surfaces of the two support plates are rotatably connected to two drive rollers distributed to the left and right, the lower ends of the two drive rollers extend to the bottom of the support plates, the lower surfaces of the two support plates are fixedly connected to L-shaped plates, and motors are installed on the lower surfaces of the two L-shaped plates. The output end of the motor passes through the L-shaped plate and is fixedly connected to one of the drive rollers.

[0010] The two drive rollers, positioned on the left and right, are connected by a belt.

[0011] To facilitate the rotation of the reverse threaded screw, as a preferred embodiment of the elevator guide rail straightening device of this utility model, a second motor is installed at the front end of the U-shaped frame, and the output end of the second motor passes through the U-shaped frame and is fixedly connected to the reverse threaded screw.

[0012] To facilitate the straightening of the guide rail, in a preferred embodiment of the elevator guide rail straightening device of this utility model, the plurality of extrusion rollers located at the front end and the plurality of extrusion rollers located at the rear end are staggered.

[0013] To prevent the threaded sleeves from rotating axially, as a preferred embodiment of the elevator guide rail straightening device of this utility model, both threaded sleeves are slidably connected to the U-shaped frame via slide rails.

[0014] For ease of operation, in a preferred embodiment of the elevator guide rail straightening device of this utility model, a controller is installed at the front end of the U-shaped frame, and the controller is electrically connected to two laser radar sensors.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, a second motor drives a reverse threaded screw to rotate. When the reverse threaded screw rotates, it drives two threaded sleeves to move relative to each other, thereby driving two mounting plates, electric push rods, extrusion plates, and extrusion rollers connected thereto to move relative to each other, so that the distance between the multiple extrusion rollers located at the front end and the multiple extrusion rollers located at the rear end matches the width of the guide rail.

[0017] As the guide rail moves between multiple extrusion rollers, it first passes through two lidar sensors. These sensors detect the distance between the guide rail and the lidar sensors. When the distance is greater than or less than a set value, it indicates that the guide rail is bent. At this point, the electric actuator can be activated to drive the corresponding extrusion plate. Based on the specific deviation value detected by the lidar sensors, the electric actuator can be controlled to drive the extrusion plate to apply the corresponding extrusion force to the bent part of the guide rail, thus performing an initial straightening operation. Then, the guide rail passes through multiple staggered extrusion rollers for further straightening.

[0018] In summary, the goal is to achieve an adjustable distance between the extrusion rollers, facilitating the straightening of guide rails of different widths, and allowing the application of appropriate extrusion force based on the degree of curvature of the guide rails, resulting in a good straightening effect.

At this time, the electric push rod 6 can be activated to drive the corresponding extrusion plate 7 and, based on the specific deviation value detected by the lidar sensors 10, control the electric push rod 6 to drive the extrusion plate 7 to apply the corresponding extrusion force to the bent part of the guide rail, and perform the initial straightening operation on the bent part of the guide rail. Then, the guide rail passes through multiple staggered extrusion rollers 8 for further straightening operation.

[0032] In this embodiment: the guide rail is placed between multiple drive rollers 12 distributed in the front and rear, and two motors 11 are started to rotate in opposite directions, thereby driving the drive rollers 12 connected to them to rotate relative to each other. At the same time, another drive roller 12 is driven to rotate simultaneously through a belt. This process serves to transport the guide rail.

[0040] In this embodiment, the controller 15 is electrically connected to the two lidar sensors 10, which facilitates signal transmission.

[0041] Working principle: First, the second motor 14 drives the reverse threaded screw 2 to rotate. When the reverse threaded screw 2 rotates, it drives the two threaded sleeves 3 to move relative to each other, thereby driving the two mounting plates 5, electric push rods 6, extrusion plates 7 and the extrusion rollers 8 connected thereto to move relative to each other, so that the distance between the multiple extrusion rollers 8 at the front end and the multiple extrusion rollers 8 at the rear end matches the width of the guide rail.

[0042] As the guide rail moves between multiple extrusion rollers 8, it first passes through two lidar sensors 10. The distance between the guide rail and the lidar sensors 10 can be detected by the two lidar sensors 10, and the signal is transmitted to the controller 15. When the distance is greater than or less than the set value, it proves that the guide rail is bent.
