Technical Field
[0001] This utility model relates to the field of elevator equipment technology, and in particular to an elevator guide rail positioning device. Background Technology
[0002] Accurate positioning of elevator guide rails is crucial during elevator installation and maintenance.
[0003] Traditional elevator guide rail positioning methods have many shortcomings, such as low positioning accuracy, which makes it difficult to meet the high precision requirements of modern high-speed elevators; complex installation process, which consumes a lot of manpower and time costs; and poor stability of the positioning device, which makes the guide rail prone to displacement during long-term elevator operation, affecting the safe operation of the elevator.
[0004] Therefore, this utility model proposes an elevator guide rail positioning device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose an elevator guide rail positioning device.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an elevator guide rail positioning device, comprising:
[0007] An elevator guide rail has two guide rail fixing holes, which are symmetrical about the vertical line of the elevator guide rail.
[0008] The limiting clamping assembly consists of two clamping frames disposed on both sides of the elevator guide rail. Each clamping frame has a guide rail snap-fit groove and is snapped onto both sides of the elevator guide rail through the guide rail snap-fit groove. Each of the two clamping frames has a tightening block snap-fit groove on the side that is close to each other.
[0009] The tightening and fixing assembly consists of a tightening block disposed between two clamping frames. The clamping frames are engaged with both sides of the tightening block via clamping block locking grooves. A bidirectional lead screw is rotatably connected inside the tightening block. A strip-shaped toothed groove is provided at the center of the bidirectional lead screw. Sliding grooves are provided on both sides of the bidirectional lead screw inside the tightening block. A lead screw sleeve that is threadedly connected to the bidirectional lead screw is slidably connected inside the sliding grooves. A threaded rod is provided at the end of the lead screw sleeve away from the bidirectional lead screw. A transmission gear and an eccentric gear are provided on one side of the strip-shaped toothed groove inside the tightening block.
[0010] Furthermore, an anti-slip pad is provided on the side of the tightening block near the elevator guide rail, and the other side of the anti-slip pad is in contact with the surface of the elevator guide rail.
[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: an anti-slip pad is thoughtfully provided on the side of the tightening block near the elevator guide rail. The anti-slip pad not only has excellent anti-slip performance, but also has a certain degree of flexibility and cushioning effect. When its other side is in close contact with the surface of the elevator guide rail, it can effectively increase the friction force, prevent the tightening block from sliding between the guide rail and the guide rail, ensure the stability and safety of the elevator operation, and provide passengers with more reliable travel protection.
[0012] Furthermore, a mounting bracket is provided on the side of the tightening block away from the clamping frame. There are two mounting brackets in total, and the two mounting brackets are symmetrical about the center of the tightening and fixing component. Both mounting brackets are L-shaped structures, and the vertical ends of both mounting brackets are provided with wall fixing holes.
[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: The tightening block is cleverly provided with a mounting bracket on the side away from the clamping frame. The two mounting brackets are L-shaped and symmetrically distributed around the center of the tightening and fixing components. Their vertical ends are provided with wall fixing holes, which facilitates the use of bolts and other connecting parts to securely connect to the wall, ensuring that the entire device is firmly installed and will not shake or shift during use, greatly enhancing the stability of the equipment and effectively ensuring its normal operation.
[0014] Furthermore, the transmission gear and the eccentric gear are rotatably connected inside the tightening block. The transmission gear is rotatably connected between the eccentric gear and the double-acting lead screw. The strip tooth groove, the transmission gear, and the eccentric gear are meshed together. One side of the eccentric gear passes through the tightening block.
[0015] The beneficial effects of adopting the above-mentioned further solution are: the transmission gear and the eccentric gear are flexibly connected inside the tightening block, the transmission gear is located between the eccentric gear and the double-acting screw, the strip tooth groove, the transmission gear and the eccentric gear mesh with each other, the ingenious transmission structure can efficiently convert the rotation of the double-acting screw into the unique motion of the eccentric gear, one side of the eccentric gear passes through the tightening block, accurately realizes the corresponding function, and provides stable and reliable power transmission for equipment operation.
[0016] Furthermore, the clamping frame has clamping mounting holes on both sides of the guide rail slot, and the size of the clamping mounting holes is adapted to the size of the guide rail fixing holes.
[0017] The beneficial effects of adopting the above-mentioned further solution are: the clamping frame is provided with clamping installation holes on both sides of the guide rail slot, which are adapted to the size of the guide rail fixing hole. During installation, the two can be precisely aligned. With the help of bolts and other connecting parts, the clamping frame and the elevator guide rail are tightly connected, which greatly improves the stability of the connection, effectively prevents the two from shifting or loosening during elevator operation, ensures the safety and stability of elevator operation, and extends the service life of the equipment.
[0018] Furthermore, the clamping frame has a tightening and fixing hole located in the tightening block slot.
[0019] The beneficial effects of adopting the above-mentioned further solution are: the clamping frame is provided with a tightening and fixing hole in the tightening block snap-fit groove. This design is of great significance. After the tightening block and the clamping frame are snapped into place, the tightening block can be firmly fixed on the clamping frame by installing bolts and other fasteners in the tightening and fixing hole, so as to avoid relative displacement between the two during the operation of the equipment, ensure the stability of the entire device structure, and allow the various components of the equipment to work together to complete the task efficiently.
[0020] Furthermore, the threaded rod is disposed through the tightening and fixing hole, and a fixing nut is threadedly connected to the end of the tightening and fixing hole away from the lead screw sleeve.
[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: the threaded rod passes through the tightening and fixing hole, and at the end away from the screw sleeve, it is threadedly connected to the fixing nut. This design allows for flexible adjustment of the tightening force of the threaded rod on the tightening block by tightening the fixing nut, accurately adapting to different installation requirements, ensuring that the tightening block and the clamping frame are tightly fitted and firmly connected, effectively enhancing the stability of the overall structure and ensuring the safe and reliable operation of the equipment.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0023] 1. In this utility model, the tightening and fixing assembly consists of a tightening block located between two clamping frames. The clamping frames are secured to both sides of the clamping block via locking grooves, making installation convenient and stable. Inside the tightening block, a bidirectional lead screw rotates, and the central strip tooth groove cooperates with the transmission gear and eccentric gear to achieve precise transmission. In the sliding grooves on both sides, the lead screw sleeve is threadedly connected to the bidirectional lead screw. Rotating the lead screw can drive it to slide along the groove, causing the two lead screw sleeves to move closer or further apart, thereby adapting to the installation of guide rail fixing holes of different widths. This allows the clamping frame to be tightened and fixed after being locked into the guide rail fixing hole, thus improving the applicability of the device.
[0024] 2. In this utility model, the limiting clamping assembly consists of two clamping frames placed on both sides of the elevator guide rail. The guide rail locking groove on the clamping frame can accurately fit the elevator guide rail and lock tightly, effectively preventing the elevator guide rail from shaking or shifting during operation, ensuring the stability of the elevator operation. The tightening block locking groove opened on the side of the two clamping frames close to each other provides an interface for the subsequent installation of tightening and fixing components, which facilitates further reinforcement of the overall structure, enhances the stability and safety of the equipment, and ensures the long-term reliable operation of the elevator.
