Description

Counterweight adjustment device for elevator tensioner module installation Technical Field

[0001] This utility model relates to the field of tensioner technology, and in particular to a counterweight adjustment device for installing an elevator tensioner module. Background Technology

[0002] The elevator tensioner pulley is a key component of the governor-safety brake system. It tightens the steel cable using counterweights or spring force, ensuring the governor can monitor the car's speed in real time. When the steel cable weakens or travels too fast, and the tensioner pulley can no longer maintain tension, it falls along with its mounting bracket. An extension rod on one side of the bracket activates the emergency brake switch inside the elevator, immediately braking the car and preventing a fall.

[0003] The tension wheel module is movably installed on a fixed position at the bottom of the elevator shaft. A buffer spring is installed between the two. During the initial installation, the spring force between the tension wheel module and the fixed position needs to be adjusted to ensure that while the counterweight drives the tension wheel module to fall, the tension wheel can tighten the steel wire rope and the extension rod is installed above the emergency brake switch. Operators usually observe the compression of the springs. If there are not enough buffer springs, the spring force is insufficient, the tension wheel module falls too low, and the extension rod cannot be kept above the brake switch. In this case, the number of buffer springs needs to be increased. Operators need to disassemble the tension wheel module and weld more springs to the back of the mounting bracket before reinstalling it on the fixed position and observing again. There are situations where multiple adjustments are required. Therefore, adjusting the installation of the tension wheel module consumes a lot of time, resulting in reduced installation efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a counterweight adjustment device for installing an elevator tensioner module, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A counterweight adjustment device for installing an elevator tensioner module includes a mounting frame and an adjustment assembly mounted on one side of the mounting frame. The adjustment assembly includes a mounting plate, a fixing plate, a first spring, and a second spring. The fixing plate is fixed to the wall of the elevator shaft. The mounting plate is fixedly mounted on the outer wall of one side of the mounting frame and is movably positioned above the fixing plate. The first spring is installed between the mounting plate and the fixing plate. Two sliding grooves are formed through the outer walls of both the mounting plate and the fixing plate, and the two sets of sliding grooves are symmetrically arranged. The second spring is movably installed between the sliding grooves of the mounting plate and the fixing plate. Slider blocks are fixedly installed at both the upper and lower ends of the second spring, and the sliders are embedded inside the sliding grooves.

[0007] Preferably, the fixing plate is an L-shaped curved plate, one edge of which is used to fix it to the elevator shaft wall. A lifting groove is provided on one outer wall of the fixing plate, and a guide block is fixedly installed on one outer wall of the mounting frame. The guide block is embedded in the lifting groove.

[0008] Preferably, the mounting plate has a through-hole groove at its center, and the fixing plate has an annular groove at its center on the upper outer wall. The annular groove does not penetrate the fixing plate. A fitting plate, made of magnet material, is fitted into the fitting groove of the mounting plate. A fitting ring is fitted into the annular groove of the fixing plate. The spring is fixedly installed between the fitting plate and the fitting ring. A threaded tube is fixedly installed at the center of the fixing plate, communicating with the center of the fitting ring. A screw is threaded into the threaded tube, and the screw is located inside the spring.

[0009] The beneficial effects of this utility model are: by setting an adjustment component, the screw can lift the entire mounting frame, giving the operator more installation space. In addition, with the sliding grooves on the mounting plate and the fixing plate, the spring can be quickly installed and removed, saving the time that would otherwise be required to disassemble the mounting frame and improving installation efficiency.

[0016] As shown in Figures 1-4, a counterweight adjustment device for installing an elevator tensioner module includes a mounting frame 1 and an adjustment assembly installed on one side of the mounting frame 1. The adjustment assembly includes a mounting plate 2, a fixing plate 3, a first spring 6, and a second spring 10. The fixing plate 3 is fixed to the wall of the elevator shaft. The mounting plate 2 is fixedly installed on the outer wall of one side of the mounting frame 1 and is movably positioned above the fixing plate 3. The first spring 6 is installed between the mounting plate 2 and the fixing plate 3. Two sliding grooves 4 are formed through the outer walls of both the mounting plate 2 and the fixing plate 3, and the two sets of sliding grooves 4 are symmetrically arranged. The second spring 10 is movably installed between the sliding grooves 4 of the mounting plate 2 and the fixing plate 3. Slider 9s are fixedly installed at both the upper and lower ends of the second spring 10, and the slider 9s are embedded inside the sliding grooves 4.

[0017] The fixing plate 3 is L-shaped curved plate. One edge of the fixing plate 3 is used to fix it to the elevator shaft wall. A lifting groove 11 is opened on one side of the outer wall of the fixing plate 3. A guide block 12 is fixedly installed on one side of the outer wall of the mounting bracket 1. The guide block 12 is embedded in the lifting groove 11.

[0018] A fitting groove is formed through the center of the mounting plate 2. An annular groove is formed in the middle of the upper outer wall of the fixing plate 3. The annular groove does not penetrate the fixing plate 3. A fitting plate 7, made of magnet, is fitted into the fitting groove of the mounting plate 2. A fitting ring 5 is fitted into the annular groove of the fixing plate 3. A spring 6 is fixedly installed between the fitting plate 7 and the fitting ring 5. A threaded tube is fixedly installed at the center of the fixing plate 3. The threaded tube communicates with the center of the fitting ring 5. A screw 8 is threaded into the threaded tube and is located inside the spring 6.

[0019] Example: During the installation phase, an extension rod is fixedly installed on one edge of the mounting frame 1. The end of the extension rod is located above the elevator emergency brake switch. First, a tension wheel is installed on one side of the mounting frame 1 via a bearing. Then, the elevator cable is looped onto the tension wheel. Finally, a counterweight is fixedly installed at the bottom of the mounting frame 1. The counterweight causes the mounting frame 1 to sink. The guide block 12 of the mounting frame 1 slides down in the lifting groove 11 of the fixed plate 3. The lifting groove 11 serves as a guide. Then, the operator observes the compression of spring 6 and spring 10. If the mounting frame 1 sinks to the designated position and the extension rod remains above the brake switch after sinking, it means that the tension wheel module is installed in place.

[0020] If the extension rod is lowered too low, it will trigger the brake switch. In this case, the spring resistance between the mounting plate 2 and the fixing plate 3 needs to be adjusted. A cross groove is provided at the bottom of the screw 8. The operator can use an electric screwdriver to rotate the screw 8. The screw 8 rotates and its end contacts the fitting plate 7. The screw 8 then continues to rotate, continuously raising the fitting plate 7. The fitting plate 7 drives the mounting plate 2, which in turn drives the mounting bracket 1 to rise. The screw 8 stops after rotating to its limit position. The spring 6 between the fitting ring 5 and the fitting plate 7, and the spring 10 between the two sliders 9, are all stretched. The mounting plate 2 is made of ferrous metal. Therefore, the interlocking plate 7 and the mounting plate 2 are fixed by adsorption. At this time, the operator can insert another set of two sliders 9 and spring 10 into the slide groove 4. The slider 9 above spring 10 is inserted into the slide groove 4 of the mounting plate 2, and the slider 9 below is inserted into the slide groove 4 of the fixing plate 3. The operator can judge the sinking situation of the extension rod and add a few more elastic resistance components. Then the operator rotates the screw 8 again to make the mounting frame 1 drop as a whole. Observe the sinking position of the mounting frame 1. If it sinks to the right position, no adjustment is needed. If the sinking position is still too low, resistance components can be added.

[0021] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
