Description

Technical Field

[0001] This application relates to the technical field of elevator guide rail installation, and in particular to a safety fixing device for elevator guide rail installation. Background Technology

[0002] Elevator guide rails are the safety tracks for elevators as they move up and down the shaft. The guide rails are installed on the shaft wall and fixed to the shaft wall by guide rail brackets and supports. The most commonly used elevator guide rails are "T"-shaped guide rails, which are characterized by high rigidity, high reliability, safety, and low cost. The guide rail surface must be smooth, without any obvious unevenness. Since the guide rails are the shuttle tracks for the guide shoes and safety brakes on the elevator car, the clearance must be ensured during installation. Furthermore, the guide rails must bear the responsibility of stopping the elevator in the event of an overspeed accident, so their rigidity cannot be ignored.

[0003] A search revealed Chinese patent application CN202020141208.6, which discloses an elevator guide rail vibration damping connection device. The device includes a wall-mounted fixing component and a guide rail connector. The wall-mounted fixing component is fixedly installed on the shaft wall, and the guide rail connector is connected to the wall-mounted fixing component and the guide rail. At least one of the wall-mounted fixing component and the guide rail connector has a vibration damping pad on its surface. This invention uses a vibration damping pad to reduce friction between the guide rail connector and the shaft wall or guide rail caused by elevator vibration during elevator operation, thus providing a buffering effect, extending the service life of the guide rail connector and the guide rail, ensuring the safety and stability of elevator operation, and simultaneously reducing elevator operating noise, protecting the ears of passengers inside the car.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the process of use, the guide rail and the guide rail frame are usually connected by bolts and nuts. During long-term use, alternating stress may occur at the connection points, resulting in fatigue and causing the guide rail to loosen. Once loosened, it may affect the stability of the elevator movement and pose a safety hazard. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a safety fixing device for installing elevator guide rails. For example... Figure 1-4 As shown, the system includes a guide rail frame 1, a load-bearing rod 2 fixedly connected to one side of the guide rail frame 1, an elevator guide rail body 3 slidably fitted on the upper part of the load-bearing rod 2, a tightening nut 4 threadedly fitted on the load-bearing rod 2, a tightening groove 5 opened on the lower side of the guide rail frame 1, two tightening blocks 6 slidably fitted in the tightening groove 5, an L-shaped block 7 fixedly connected to the opposite side of the two tightening blocks 6, a connecting plate 8 fixedly connected to one side of the L-shaped block 7, and a pressure switch 9 fixedly connected to one side of the connecting plate 8.

[0024] Please see Figure 1 Anti-slip plates 18 are fitted on both load-bearing rods 2. The anti-slip plates 18 abut against the elevator guide rail body 3. The anti-slip plates 18 on the load-bearing rods 2, between the elevator guide rail body 3 and the tightening nut 4, increase the stability of the tightening nut 4.

[0025] Please see Figure 1 One end of the guide rail frame 1 is fixedly connected to the mounting base 19, and the mounting base 19 and the guide rail frame 1 are welded together. Multiple linkage ports 20 are opened on one side of the mounting base 19. By inserting the corresponding connectors through the linkage ports 20, the mounting base 19 can be fixed to the wall, thereby fixing the guide rail frame 1.

[0026] Please see Figure 4 Two force-bearing plates 22 are fixedly connected to one side of the connecting plate 8. The two force-bearing plates 22 are located on both sides of the pressure switch 9. When the elevator guide rail body 3 becomes loose and collides with the pressure switch 9, the force-bearing plate 22 can bear a certain amount of force to avoid excessive shaking and damage to the pressure switch 9.

[0027] A processing box 10 is fixedly connected to one side of the L-shaped block 7. The processing box 10 and the pressure switch 9 cooperate with each other. A limit plate 11 is fixedly connected to the upper side of the connecting plate 8. The limit plate 11 cooperates with the load-bearing rod 2. A drive mechanism 13 is provided on the inner wall of the tightening groove 5.

[0028] Please see Figure 3 The drive mechanism 13 includes a bidirectional lead screw 131 rotatably fitted on the inner wall of the tightening groove 5 and an operating disc 132 fixedly connected to one side of the bidirectional lead screw 131. One end of the bidirectional lead screw 131 extends to one side of the guide rail frame 1 and is rotatably fitted. The bidirectional lead screw 131 is threadedly fitted with two tightening blocks 6. The bidirectional lead screw 131 can be easily operated by holding the operating disc 132. The bidirectional lead screw 131 drives the two tightening blocks 6, causing them to move the L-shaped blocks 7 accordingly.

[0029] Please see Figure 3 An anti-slip sleeve 21 is fixedly connected to the control panel 132. The anti-slip sleeve 21 is provided with anti-slip texture. When the control panel 132 is operated, the anti-slip texture on the anti-slip sleeve 21 can increase the anti-slip stability of the operation.

[0030] Please see Figure 3 A limiting groove 14 is provided on one side of the guide rail frame 1, and a movable opening 15 is provided on one side of the operation panel 132. A locking pin 16 that cooperates with the limiting groove 14 is slidably fitted on the inner wall of the movable opening 15. A tension spring 17 is provided between the locking pin 16 and the operation panel 132. The locking pin 16 is pulled by the tension spring 17, so that the locking pin 16 is inserted into the limiting groove 14, which can strengthen the operation panel 132 and prevent the bidirectional lead screw 131 from loosening.

[0031] The implementation principle of the safety fixing device for elevator guide rail installation in this application embodiment is as follows: When in use, the guide rail frame 1 is fixed by passing a collision screw through the linkage port 20 of the mounting base 19. After the fixing is completed, the elevator guide rail body 3 is fixed by tightening the nut 4 on the load-bearing rod 2, thereby realizing the installation of the elevator guide rail body 3.

[0032] Then, the hand-held control panel 132 drives the bidirectional lead screw 131 to rotate, which tightens the tightening block 6, causing the corresponding L-shaped block 7, connecting plate 8, and limit plate 11 to move. Then, the pressure switch 9 will fit against one side of the elevator guide rail body 3. Once the elevator guide rail body 3 becomes loose, it will be displaced during guidance, causing pressure on the pressure switch 9 and transmitting a signal to the processing box 10. The processing box 10 is connected to the external property monitoring to realize an alarm, allowing maintenance personnel to carry out timely repairs and take measures before an accident occurs, ensuring the safety of passengers and improving the safety of the installation.

[0033] After the movement, the limiting plate 11 will abut against one side of the load-bearing rod 2, thereby limiting the tightening nut 4. If the tightening nut 4 loosens, it will not detach from the load-bearing rod 2, so that the load-bearing rod 2 will always support the elevator guide rail body 3, preventing loosening and falling off, and achieving safety protection.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
