[0002] The connecting device of the elevator rope head plate is an important part of the traction system in the elevator industry, and its function is to ensure the reliable connection between the traction steel wire rope and the elevator car, the counterweight device or the machine room load-bearing beam. The normal operation of the elevator depends on an accurate suspension system, in which the rope head assembly and the rope head plate connecting device play a crucial role, affecting the safety performance and operation efficiency of the elevator.

[0003] During the design and installation of the elevator, the rope head plate connecting device often adopts a welding method for fixation to ensure the structural stability and long-term reliability. The welding process is complex, difficult to repair and replace, the complexity of changing the traction method is high, and the equipment and labor costs increase. Welding operations require professional equipment and skilled operators. During the welding process, the temperature and welding materials need to be strictly controlled to prevent deformation or damage of the rope head plate. Once the welding is completed, if the rope head device needs to be repaired or replaced, it usually requires cutting and re-welding, which not only increases the repair cost, but also may damage the rope head plate. Changing the traction method of the elevator may involve repositioning or adding rope head devices. For the welding method, this usually means a large amount of re-welding work. A large amount of welding operations not only increase the operation risk, but also may lead to an extended system downtime, affecting the normal use of the elevator. Welding operations require professional welding equipment and operators, increasing the initial installation and subsequent maintenance costs. Summary of the Utility Model

[0021] 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.

[0022] Please refer to Figures 1 to 3 As shown, the present invention is a connecting device for an elevator rope socket board, including an upper plate structure 1, and a lower plate structure 2 is detachably and fixedly arranged below the upper plate structure 1 through a positioning bolt 3.

[0023] The upper plate structure 1 includes an upper connecting plate 11. Two rows of upper through holes 112 are opened along the center on the surface of the upper connecting plate 11 according to a predetermined design. A Chinese character-shaped lifting hole 113 is opened inside the upper connecting plate 11 on one side of the upper through hole 112. Limiting rods 114 are slidably arranged inside the lifting holes 113. The limiting rods 114 are of a T-shaped structure and are slidably and limitedly arranged inside the lifting holes 113 through springs 115. The lower ends of the limiting rods 114 are provided with balls, and the balls are always in active contact with the upper surface of the lower connecting plate 21. Fixed side plates 111 are integrally arranged on the left and right sides of the upper connecting plate 11, and through mounting through holes are opened on the surfaces of the fixed side plates 111.

[0024] The lower plate structure 2 includes a lower connecting plate 21. Through lower through holes 211 are opened on the surface of the lower connecting plate 21 corresponding to the positions of the upper through holes 112. The lower through holes 211 are in a dart-shaped structure on the surface of the lower connecting plate 21. Plate bodies extending downward are integrally connected to both sides of the lower connecting plate 21, and five through strip-shaped bolt positioning grooves 212 are opened on the side surfaces of the plate bodies. Among them, the bolt positioning groove 212 in the middle position is the largest, and the other four strip-shaped bolt positioning grooves 212 are annularly distributed along the bolt positioning groove 212 in the middle position. Open sliding grooves are opened from the center position to both sides inside the extending plate bodies on both sides of the lower connecting plate 21, and movable mounting arms 22 are slidably arranged inside the sliding grooves. The movable mounting arms 22 are L-shaped plate bodies, and the extending plate bodies on both sides of the movable mounting arms 22 are also provided with bolt positioning grooves 212 corresponding to the lower connecting plate 21.

[0025] During operation, the upper connecting plate 11 is fixed to the surface of the support crossbeam through the fixed side plate 111 and bolts. After fixation, the lower connecting plate 21 is placed flat below the upper connecting plate 11, and then the upper connecting plate 11 and the lower connecting plate 21 are fixed through the positioning bolts 3. Then, the lower connecting plate 21 is fixed through bolts and the bolt positioning grooves 212. Then, the elevator rope socket can be arranged and connected to the elevator car. After the elevator is assembled, if adjustment is required, a lifting device can be used to position the elevator car. After positioning, the elevator rope socket is disassembled, and then the lower connecting plate 21 is adjusted. During the rotation process, the limiting rod 114 will pop out from the inside of the lifting hole 113 under the action of the spring 115. When the lower connecting plate 21 and the upper connecting plate 11 are in a cross state, the popped limiting rod 114 will limit the lower connecting plate 21. Then, the adjusted upper connecting plate 11 and the lower connecting plate 21 are fixed through the positioning bolts 3. After fixation, the stretchable movable mounting arm 22 can be extended so that it extends out from the inside of the lower connecting plate 21, ensuring that the movable mounting arm 22 adheres to the surface of the support crossbeam. Then, the extended movable mounting arm 22 is fixed again through bolts and the bolt positioning grooves 212. After fixation, the lower connecting plate 21 and the support crossbeam are fixed through bolts and the movable mounting arm 22. Then, the elevator rope socket is rearranged and connected to the elevator car, and it can be tested again after assembly.

[0026] In summary, through the settings of the upper connecting plate 11, the fixed side plate 111, the upper through-hole 112, the lifting hole 113, the limiting rod 114, the spring 115, the lower connecting plate 21, the lower through-hole 211, the bolt positioning grooves 212, and the movable mounting arm 22, by using a layered design, a rotatable adjustment method, and the stretchable movable mounting arm 22, even after fixation, it still has the ability to be rotated and adjusted after being loosened. In this way, it can easily and conveniently change the perforation hole position of the elevator rope socket and realize the adjustment of the elevator rope socket. Compared with the current elevator rope socket plate, it can greatly reduce the operation difficulty and workload during adjustment. At the same time, with the design of the above structure, during the process of adjusting and changing the holes, it still has a one-layer support structure, which can greatly reduce the load intensity of the lifting device, and it is not necessary to replace all the elevator rope sockets. Only the corresponding elevator rope sockets need to be replaced, and the safety and convenience will be greatly improved, which is more conducive to reducing the time required for elevator assembly and maintenance.

[0027] The working principle is as follows: First, weld and fix the supporting crossbeam above the hoistway, and ensure that there is enough space between the crossbeams for placing the lower connecting plate 21 and rotation. Then, fix the upper connecting plate 11 on the surface of the supporting crossbeam through the fixed side plate 111 and bolts. After fixing, place the lower connecting plate 21 flat under the upper connecting plate 11, and then fix the upper connecting plate 11 and the lower connecting plate 21 through the positioning bolts 3. Then, fix the lower connecting plate 21 through bolts and bolt positioning grooves 212. Then, the elevator rope socket can be arranged and connected to the elevator car. After the elevator is assembled, the elevator can be inspected, and the state of the elevator rope socket plate connecting device can be detected during the inspection. If there are unstable conditions, affecting the elevator rope socket, or maintenance is required, after the elevator stops, use lifting equipment to position the elevator car. After positioning, disassemble the elevator rope socket, and then adjust the position of the lower connecting plate 21. During the rotation process, the limiting rod 114 will pop out from the inside of the lifting hole 113 under the action of the spring 115. When the lower connecting plate 21 and the upper connecting plate 11 are in a cross state, the popped-out limiting rod 114 will limit the lower connecting plate 21. Then, fix the adjusted upper connecting plate 11 and the lower connecting plate 21 through the positioning bolts 3. After fixing, stretch the movable mounting arm 22 so that it extends out from the inside of the lower connecting plate 21, ensuring that the movable mounting arm 22 is attached to the surface of the supporting crossbeam. Then, fix the extended movable mounting arm 22 again through bolts and bolt positioning grooves 212. After fixing, fix the lower connecting plate 21 and the supporting crossbeam through bolts and the movable mounting arm 22. Then, rearrange the corresponding elevator rope sockets that need to change holes, and after connecting and assembling with the elevator car, it can be detected and used again.

[0028] The above are only the preferred embodiments of the present invention, which do not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
