Description

Technical Field

[0001] This utility model relates to the field of elevator lifting technology, specifically a new type of backpack frame elevator lifting structure. Background Technology

[0002] The lifting structure is used to connect the wire rope and the car. The lifting structure is equipped with a rope end cone sleeve, which can fix one end of the wire rope to the lifting structure. After a long period of use, the wear of the wire rope on the rope end cone sleeve is greater than that of the wire rope in other parts. Currently, the general solution is to replace the entire wire rope, but this method not only increases costs but is also relatively cumbersome and inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a novel lifting structure for a backpack frame elevator, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: The lifting structure of the novel backpack frame elevator includes a bottom frame and a top frame, which are connected by two upright plates. It also includes a mounting box, on which four fixing units for fixing steel wire ropes are provided. Each fixing unit includes a base, and a fixing plate is provided inside the base. After the movable end of the steel wire rope passes around the fixing plate, it is fixed to the steel wire rope body by a clamp. A vertical rod is provided on the lower surface of the base, and the vertical rod passes through the mounting box. A detachable stop is provided at the lower end of the vertical rod. A spring is fitted on the upright, and the spring is located between the mounting box and the stop block. Fixed plates are respectively provided on both sides of the interior of the mounting box. Through slots are respectively opened on both sides of the mounting box. Push plates slide on both sides of the interior of the mounting box. A wedge is provided on one side of the push plate. An elastic element is provided between the fixed plate and the push plate. Several positioning slots are opened on the side of the upright plate. Extension plates are respectively provided on both sides of the mounting box. Through holes are opened on the extension plates. Threaded holes are opened on both sides of the positioning slots on the upright plate. The extension plates and the upright plates are connected by bolts.

[0005] Preferably, the outer surface of the fixing plate is provided with an arc-shaped groove for placing the wire rope.

[0006] Preferably, the stop block has a threaded hole, the upright has an external thread, and the stop block is threadedly connected to the upright.

[0007] Preferably, the mounting box is provided with a support plate inside.

[0008] Preferably, a noise-reducing pad is fitted onto the upright, and the noise-reducing pad is located between the mounting box and the spring.

[0009] The beneficial effects of this utility model are:

[0010] The position of the mounting box in this lifting structure can be adjusted, so that after the movable end of the severely worn wire rope is cut, the height of the mounting box can be raised so that the wire rope can still be fixed to the mounting box by the base, fixing plate and clamp, without the need to replace the entire wire rope. This can save maintenance costs, improve resource utilization while ensuring safety, and reduce the cumbersome wire rope replacement, resulting in good performance. Attached Figure Description

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-3As shown, a novel backpack frame elevator lifting structure includes a bottom frame 2 and a top frame 3, connected by two upright plates 4. It also includes a mounting box 5, which has four fixing units for securing steel wire ropes 6. Each fixing unit includes a base 7, with a fixing plate 8 inside. The movable end of the steel wire rope 6 passes over the fixing plate 8 and is then fixed to the steel wire rope body by a clamp 9. An upright 10 is provided on the lower surface of the base 7, penetrating the mounting box 5. A detachable stop 11 is provided at the lower end of the upright 10, and a spring 1 is fitted onto the upright 10. 2. Spring 12 is located between mounting box 5 and stop block 11. Fixing plates 13 are respectively provided on both sides of the interior of mounting box 5. Through slots are opened on both sides of mounting box 5. Push plates 14 slide on both sides of the interior of mounting box 5. A wedge block 15 is provided on one side of push plate 14. An elastic element 16 is provided between fixing plate 13 and push plate 14. Several positioning slots 17 are opened on the side of upright plate 4. Extension plates 18 are respectively provided on both sides of mounting box 5. Through holes are opened on extension plates 18. Threaded holes 19 are opened on both sides of upright plate 4 located in the positioning slots 17. Extension plates 18 and upright plate 4 are connected by bolts.

[0017] The car 1 of the backpack frame elevator is installed between the top frame 3 and the bottom frame 2, and the mounting box 5 and the components attached to the mounting box 5 are located on the side of the car 1.

[0018] After the movable end of the wire rope 6 is fixed to the wire rope 6 body by the clamp 9, the friction of the wire rope 6 at the clamp 9 position is relatively severe as the wire rope 6 repeatedly pulls the car 1 up and down. During elevator maintenance, firstly, all the clamps 9 fixing the wire rope 6 are removed, then the bolts connecting the extension plate 18 and the vertical plate 4 are removed, and then the mounting box 5 is pushed upward. During the upward movement of the mounting box 5, the wedge 15 will abut against the positioning groove 17 and will be squeezed. The wedge 15 compresses the elastic element 16 between the push plate 14 and the fixed plate 13 through the push plate 14. When the wedge 15 is completely removed from the positioning groove 17, Continue pushing the mounting box 5 upward until it reaches a certain height. At this point, the wedge 15 can re-enter the positioning groove 17 under the action of the elastic element 16. After the two wedges 15 in the mounting box 5 enter the positioning groove 17 on the vertical plate 4, the mounting box 5 no longer needs to be supported. This makes it easier to fix the mounting box 5. When fixing the mounting box 5, connect the extension plate 18 to the vertical plate 4 with bolts. Then, cut off the severely worn part of the movable end of the wire rope 6. Then, pass the new movable end of the wire rope 6 around the fixing plate 8. Finally, fix the movable end of the wire rope 6 to the wire rope 6 body with the clamp 9.

[0019] Since the wire rope 6 passes through the inside of the base 7, the wire rope 6 will not come off the fixing plate 8 under normal circumstances after the clamp 9 fixes the movable end of the wire rope 6 to the body of the wire rope 6.

[0020] Furthermore, the outer surface of the fixing plate 8 is provided with an arc-shaped groove for placing the wire rope 6, so as to avoid excessive compression and wear in the part of the wire rope 6 that contacts the fixing plate 8.

[0021] Furthermore, the stop block 11 has a threaded hole 19, and the upright 10 has an external thread. The stop block 11 and the upright 10 are threadedly connected, which facilitates the adjustment of the tension of the spring 12 on the upright 10.

[0022] Furthermore, the interior of the mounting box 5 is equipped with a support plate 20, which helps to improve the bending resistance of the mounting box 5.

[0023] Furthermore, a noise-reducing pad 21 is fitted on the upright 10. The noise-reducing pad 21 is located between the mounting box 5 and the spring 12. The noise-reducing pad 21 is made of rubber and is used to reduce the friction noise between the spring 12 and the mounting box 5.

[0024] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
