Description

Technical Field

[0001] This utility model relates to the field of home elevator technology, specifically a counterweight device for a home elevator. Background Technology

[0002] The counterweight is a component of the elevator traction system. It is located in the elevator shaft and connected to the car via the traction rope and traction sheave. During elevator operation, the counterweight moves up and down along the counterweight guide rail through the counterweight guide shoes to balance the weight of the car.

[0003] As the market for self-built elevators continues to expand and the application of home elevators becomes more widespread, the top floor and pit of home elevators are relatively small, and the decoration requirements are also quite numerous, which imposes certain limitations on the counterweight device. Therefore, in order to reduce installation requirements, the balancing range of the counterweight device in home elevators can be relatively reduced, only needing to match the weight of family members. However, the individual weight and number of family members are not constant, so the weight of the counterweight device needs to be adjusted. Currently, most counterweight frames are relatively fixed with upper and lower openings, making it inconvenient to disassemble and assemble the counterweight frame when adjusting the counterweight. Utility Model Content

[0004] The purpose of this invention is to provide a counterweight device for a home elevator to solve the problems mentioned in the background art.

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

[0006] A counterweight device for a home elevator, comprising:

[0007] A lifting frame, the lifting frame including a base frame;

[0008] The configuration frame includes a movable frame, the lower two sides of which are hinged to the lower end of the base frame, and several counterweights are snapped into the interior of the movable frame.

[0009] A locking structure is fixedly installed on both ends of the upper surface of the base frame and the movable frame.

[0010] The guide structure consists of two sets, which are fixedly installed on both sides of the lifting frame.

[0011] Furthermore, the lifting frame also includes:

[0012] Two hinge pieces are fixedly installed at both ends of the lower edge of the front surface of the base frame.

[0013] Wheel frame, which is fixedly installed in the middle of the upper surface of the base frame;

[0014] The counterweight reverse rope pulley is rotatably mounted inside the pulley frame;

[0015] A steel wire rope, said steel wire rope being wound around the side surface of the counterweight reel.

[0016] Furthermore, the lifting frame also includes:

[0017] A rope loop is fixedly installed in the middle of the lower surface of the base frame;

[0018] A compensating rope, one end of which is fixedly connected to a rope loop.

[0019] Furthermore, the configuration box also includes:

[0020] Hinge slots are provided at the lower ends of both sides of the movable frame.

[0021] Two limiting screws are provided, and the lower ends of the two limiting screws are installed in the bottom of the movable frame.

[0022] A limiting sleeve is screwed onto the side surface of the limiting screw.

[0023] Furthermore, the locking structure includes:

[0024] A hinged base is fixedly installed on the upper surface of the base frame;

[0025] A threaded rod, the rear end of which is rotatably connected to a hinged seat;

[0026] A snap-fit ​​connector is fixedly installed on the upper surface of the movable frame.

[0027] A snap-fit ​​groove is inserted into the middle of the snap-fit ​​seat, and the snap-fit ​​groove is snapped into the threaded rod;

[0028] A fastening nut is rotatably fitted onto one end of a threaded rod.

[0029] Furthermore, the guiding structure includes:

[0030] The corner brackets are four in number and are fixedly installed at both ends of the upper and lower surfaces of the base frame.

[0034] An I-shaped steel section is provided, with a slide rail fixedly installed on one side. The slide rail is slidably engaged with a slide groove, and one side of the slide rail rolls against an auxiliary roller.

[0035] Compared with the prior art, the beneficial effects of this utility model are:

[0036] 1. The movable frame is hinged to the lower end of the base frame and locked at the upper end by a locking structure to stabilize each counterweight block. The traditional one-piece counterweight frame is optimized into an openable frame structure composed of a base frame and a movable frame. The movable frame can be opened directly to expose the internally snap-fit ​​counterweight blocks. As needed, some counterweight blocks can be added or removed, and then the base frame and movable frame can be closed again and locked by the locking structure, which facilitates the adjustment of the actual counterweight mass.

[0037] 2. Insert the counterweight into the limiting screw and lock it into the movable frame. Then screw the limiting sleeve onto the upper end of the limiting screw. Use the limiting sleeve to abut against the upper surface of each stacked counterweight and tighten it to secure and limit the stacked counterweight. This prevents the counterweight from moving inside the base frame and movable frame due to inertia when the entire counterweight device moves up and down, thus avoiding weight changes that could affect the working effect.

Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figure 1-6 In this embodiment of the present invention, a counterweight device for a home elevator includes a lifting frame 1, a configuration frame 2, a locking structure 3, and a guide structure 4. The lifting frame 1 includes a base frame 101; the configuration frame 2 includes a movable frame 201, the lower ends of which are hinged to the lower ends of the base frame 101 on both sides, and a plurality of counterweight blocks 205 are snapped into the movable frame 201; the locking structure 3 is fixedly installed on both ends of the upper surface of the base frame 101 and the movable frame 201; the guide structure 4 consists of two sets, which are fixedly installed on both sides of the lifting frame 1.

[0047] Specifically, the lower ends of the movable frame 201 and the base frame 101 are hinged together, and the upper ends are locked by the locking structure 3 to stabilize each counterweight block 205. The traditional integrated counterweight frame is optimized into an openable frame structure composed of the base frame 101 and the movable frame 201. The movable frame 201 can be opened directly to expose the internally snap-fit ​​counterweight blocks 205. According to the needs, some counterweight blocks can be added or removed, and then the base frame 101 and the movable frame 201 can be closed again and locked by the locking structure 3, which facilitates the adjustment of the actual weight of the counterweight.

[0048] Example 1

[0049] like Figure 3As shown, in this embodiment, the lifting frame 1 further includes hinge plates 102, wheel frames 103, counterweight reverse rope pulleys 104, steel wire ropes 105, rope loops 106, and compensating ropes 107. There are two hinge plates 102, which are fixedly installed at both ends of the lower edge of the front surface of the base frame 101. The wheel frame 103 is fixedly installed in the middle of the upper surface of the base frame 101. The counterweight reverse rope pulleys 104 are rotatably installed inside the wheel frame 103. The steel wire rope 105 is wound around the side surface of the counterweight reverse rope pulleys 104. The rope loops 106 are fixedly installed in the middle of the lower surface of the base frame 101. One end of the compensating rope 107 is fixedly connected to the rope loops 106.

[0050] In this embodiment, the steel wire rope 105 passes through the counterweight sheave 104 and is connected to the home elevator car to balance the weight of the car. One end of the compensating rope 107 is connected to the rope loop 106, and the other end is connected to the bottom of the elevator car to balance the weight changes of the traction rope and traveling cable during elevator operation.

[0051] like Figure 2-5 As shown, in this embodiment, the configuration frame 2 further includes a hinge groove 202, a limiting screw 203, and a limiting sleeve 204. The hinge groove 202 is opened at the lower ends of both sides of the movable frame 201; there are two limiting screws 203, and the lower ends of the two limiting screws 203 are installed on the inner bottom of the movable frame 201; the limiting sleeve 204 is screwed onto the side surface of the limiting screw 203; the locking structure 3 includes a hinge seat 301, a threaded rod 302, a snap-fit ​​seat 303, a snap-fit ​​groove 304, and a fastening nut 305. The hinge seat 301 is fixedly installed on the upper surface of the base frame 101; the rear end of the threaded rod 302 is rotatably connected to the hinge seat 301; the snap-fit ​​seat 303 is fixedly installed on the upper surface of the movable frame 201; the snap-fit ​​groove 304 is inserted into the middle of the snap-fit ​​seat 303, and the snap-fit ​​groove 304 and the threaded rod 302 snap-fit ​​each other; the fastening nut 305 is rotatably sleeved on one end of the threaded rod 302.

[0052] In practice, after opening the movable frame 201, the counterweight 205 is inserted into the limiting screw 203 and locked inside the movable frame 201. The limiting sleeve 204 is screwed onto the upper end of the limiting screw 203. The limiting sleeve 204 is used to abut against the upper surface of each stacked counterweight 205 and tightened to secure and limit the stacked counterweight 205. This prevents the counterweight 205 from moving inside the base frame 101 and movable frame 201 due to inertia when the overall counterweight device moves up and down, thus avoiding weight changes that would affect the working effect. After the counterweight 205 is adjusted, the movable frame 201 is rotated to close with the base frame 101. The threaded rod 302 is then inserted into the locking groove 304, and the fastening nut 305 is screwed on so that the fastening nut 305 abuts against the front surface of the locking seat 303, locking the base frame 101 and movable frame 201.

[0053] Example 2

[0054] Based on Embodiment 1, this invention supplements the specific methods by which the counterweight device as a whole remains stable during operation, which were not mentioned in Embodiment 1.

[0055] like Figure 1 , Figure 6 As shown, in this embodiment, the guide structure 4 includes corner brackets 401, sliders 402, grooves 403, auxiliary rollers 404, and I-beams 405. There are four corner brackets 401, which are fixedly installed at both ends of the upper and lower surfaces of the base frame 101. The sliders 402 are fixedly installed on one side of the vertical plate of the corner brackets 401. The grooves 403 are formed on one side of the sliders 402. There are several auxiliary rollers 404, which are rotatably installed inside the grooves 403. A slide rail 406 is fixedly installed on one side of the I-beams 405. The slide rail 406 is slidably engaged with the grooves 403, and one side of the slide rail 406 rolls against the auxiliary rollers 404.

[0056] In practice, the sliding engagement of slider 402 and slide rail 406 is used to guide and limit the movement of the overall counterweight structure, ensuring the stability of the counterweight operation. At the same time, the auxiliary roller 404 is used to replace part of the inner wall of the slide groove 403 and the slide rail 406 to abut against each other, improving the smoothness of the up and down sliding.
