Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight system technology, specifically a counterweight elastic guide wheel assembly device. Background Technology

[0002] The counterweight elastic guide wheel assembly is a core component of the counterweight system in an elevator system. It is mainly used to balance the weight of the car, guide the counterweight to run smoothly along the guide rail, and absorb vibrations and shocks during operation through its elastic structure, thereby improving the safety and comfort of the elevator. The technological evolution of the counterweight elastic guide wheel assembly is shifting from single-function optimization to systemic innovation. Through the deep integration of materials, structure, and intelligent technologies, it is gradually achieving the goal of "maintenance-free, highly reliable, and sustainable".

[0003] The counterweight is connected to the car via steel wire ropes, and its weight is typically 40%-50% of the car's own weight plus the rated load. The counterweight's elastic guide wheel assembly, through its elastic support structure, ensures dynamic balance between the counterweight and the car during operation, reducing the load on the traction machine. The guide wheels in the assembly, by contacting the guide rails, limit the lateral sway of the counterweight, ensuring its vertical movement along the guide rails. Elastic elements (such as springs and rubber) automatically compensate for geometric errors and installation deviations in the guide rails, avoiding rigid collisions.

[0004] However, in actual use, the above-mentioned counterweight elastic guide wheel assembly device has two main drawbacks. First, it lacks guiding flexibility. The traditional snap-fit ​​sliding method is limited to a single dimension and fixed point, which cannot achieve multi-directional dynamic adjustment and is difficult to adapt to the multi-dimensional vibration of the counterweight system and guide rail deviation. Second, it has poor adaptability to extreme working conditions and lacks targeted protection design in its structure, resulting in short lifespan and frequent failures. Therefore, we propose a counterweight elastic guide wheel assembly device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a counterweight elastic guide wheel assembly device, which solves the problems of insufficient guiding flexibility and poor adaptability to extreme working conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a counterweight elastic guide wheel assembly device, comprising a guide wheel frame and a vertical support rod disposed on one side of the guide wheel frame. The guide wheel frame is fixedly connected to the vertical support rod, and two sets of wide pulleys are provided on the side of the guide wheel frame away from the vertical support rod. A connecting rod is installed through the wide pulleys near the guide wheel frame via a bearing component, and the connecting rod is fixedly connected to the guide wheel frame on the side near the guide wheel frame. A narrow pulley is provided on the side of the wide pulley away from the vertical support rod, and a side-mounted rod is installed through the narrow pulleys near the guide wheel frame via a bearing component. The side-mounted rod is fixedly connected to the guide wheel frame on the side near the guide wheel frame. A snap-fit ​​component is fixedly installed on the side-mounted rod away from the narrow pulley, and a side pulley is snapped and movably mounted on the side of the snap-fit ​​component away from the side-mounted rod. Two sets of upper support rods are provided on the side of the vertical support rod away from the guide wheel frame, and the upper support rods are fixedly connected to the vertical support rod.

[0007] Preferably, a mounting plate one is fixedly connected to the side of the guide wheel frame near the vertical frame rod, and the side of the mounting plate one near the vertical frame rod is fixedly connected to the vertical frame rod. A mounting plate two is fixedly connected to the side of the upper frame rod near the guide wheel frame, and the side of the mounting plate two near the vertical frame rod is fixedly connected to the vertical frame rod.

[0008] Preferably, a U-shaped mounting plate is fixedly installed on the side of the upper frame pole perpendicular to the vertical frame pole. A rope-hanging wheel is provided on the side of the U-shaped mounting plate away from the upper frame pole. A connecting rod two is installed through a bearing component on the side of the rope-hanging wheel near the upper frame pole, and the side of the connecting rod two near the upper frame pole is fixedly installed on the upper frame pole.

[0009] Preferably, a base plate is provided on the side of the vertical frame pole away from the upper frame pole, and a mounting plate three is fixedly connected to the side of the base plate near the vertical frame pole, and the mounting plate three is placed on one side of the vertical frame pole and fixedly connected to the vertical frame pole.

[0010] Preferably, a counterweight is movably installed on one side of the base plate perpendicular to the vertical support rod, and the side of the counterweight close to the vertical support rod is embedded in the vertical support rod and can slide along the inner side of the vertical support rod.

[0011] Preferably, a pressure member is provided on the side of the counterweight away from the base plate, and side plate one and side plate two are fixedly connected to the pressure member on both sides perpendicular to the counterweight. The side of side plate one and side plate two away from the pressure member are both fixedly connected to the vertical frame rod.

[0012] Preferably, the vertical support rod has a limiting hole on the side near side plate one and side plate two for use with both, which is used to limit the installation position of side plate one and side plate two; the vertical support rod has a pressure reducing groove on the side near the guide wheel frame.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, a guide wheel frame is fixedly installed on one side of the vertical support rod. The guide wheel frame is a U-shaped mounting accessory. A wide pulley is provided on the side of the guide wheel frame away from the vertical support rod. On the side of the guide wheel frame perpendicular to the wide pulley, two sets of opposing side pulleys are provided through a side mounting rod, so that the wide pulley and the two sets of side pulleys form a three-point wrap-around contact with the guide rail from the side and both sides of the vertical direction. This structure breaks through the limitation of the traditional guide wheel's "single-direction or two-dimensional contact" and can simultaneously absorb the guide rail's lateral offset, vertical vibration, and small torsional deviation, constructing a "three-dimensional wrap-around" buffer guide mechanism. Under the instantaneous impact of elevator start / brake and the lateral force of the curved section of rail transit, the wide pulley and the two sets of side pulleys compensate for the guide rail deviation in real time through elastic buffering, ensuring that the counterweight system always runs along the center trajectory of the guide rail, significantly improving the smoothness of operation.

[0014] 2. In this utility model, a narrow pulley is provided on the side of the side pulley near the guide wheel frame, and is mounted on the side mounting rod through a bearing component. This allows each set of side pulleys to rotate flexibly around the bearing component and to adaptively conform to the guide rail surface through the elastic deformation of the narrow pulley. The "all-round buffer wheel set" formed by multiple sets of guide wheels can be tightly engaged with the side and corners of the counterweight guide rail. The three-dimensional contact structure disperses the lateral force and vertical impact force of the guide rail to the wide pulley and the two sets of side pulleys, alleviating the load-bearing capacity of a single set of guide wheels. At the same time, the low-friction rotation of the bearing component, combined with the buffer adjustment of the narrow pulley, keeps the contact pressure fluctuation between the guide wheel and the guide rail within the design allowable range, avoiding uneven wear caused by local stress concentration and improving the overall adaptability of the guide wheel set.

[0018] refer to Figures 1-5 The counterweight elastic guide wheel assembly shown includes a guide wheel frame 1 and a vertical support rod 2 disposed on one side of the guide wheel frame 1. A specific embodiment is shown below: Example

[0019] The guide wheel frame 1 is fixedly connected to the vertical support rod 2.

The side of the mounting plate 107 that is close to the vertical frame rod 2 is fixedly connected to the vertical frame rod 2. Example

[0020] Two sets of upper frame rods 3 are provided on the side of the vertical frame rod 2 away from the guide wheel frame 1, and the upper frame rods 3 are fixedly connected to the vertical frame rod 2. The side of the upper frame rod 3 near the guide wheel frame 1 is fixedly connected to the mounting plate 2, and the side of the mounting plate 2 near the vertical frame rod 2 is fixedly connected to the vertical frame rod 2. A U-shaped mounting plate 601 is fixedly installed on the side of the upper frame rod 3 perpendicular to the vertical frame rod 2. A rope-hanging wheel 6 is provided on the side of the U-shaped mounting plate 601 away from the upper frame rod 3. A connecting rod 2 602 is installed through a bearing on the side of the rope-hanging wheel 6 near the upper frame rod 3, and the connecting rod 2 602 is fixedly installed on the side of the upper frame rod 3 near the upper frame rod 3. Example

[0021] A base plate 4 is provided on the side of the vertical support rod 2 away from the upper support rod 3. A mounting plate 3 401 is fixedly connected to the side of the base plate 4 near the vertical support rod 2, and the mounting plate 3 401 is placed on one side of the vertical support rod 2 and fixedly connected to the vertical support rod 2. A counterweight 503 is movably installed on the side of the base plate 4 perpendicular to the vertical support rod 2, and the side of the counterweight 503 near the vertical support rod 2 is embedded in the vertical support rod 2 and can slide along the inner side of the vertical support rod 2. A pressure member is provided on the side of the counterweight 503 away from the base plate 4. 5. The pressure member 5 is fixedly connected to two sides of the counterweight 503, with side plate 1 501 and side plate 2 502 respectively. The side of side plate 1 501 and side plate 2 502 away from the pressure member 5 are fixedly connected to the vertical frame rod 2. The vertical frame rod 2 is provided with a limiting hole 202 on the side of side plate 1 501 and side plate 2 502 for use with both, which is used to limit the installation position of side plate 1 501 and side plate 2 502. The vertical frame rod 2 is provided with a pressure reducing groove 201 on the side of the guide wheel frame 1.

[0022] Working principle of this utility model: First, the device uses the vertical frame rod 2 as the core load-bearing and limiting skeleton, and lays the working foundation through multiple sets of rigid connection structures. The guide wheel frame 1 is rigidly fixed to the vertical frame rod 2 via mounting plate 107, forming the mounting base for the guide wheel assembly; the guide wheel frame 1 is designed with a U-shaped structure, its opening facing the counterweight guide rail, reserving space for the subsequent "wrapped guidance" of the pulley assembly; two sets of upper frame rods 3 are fixed to the top of the vertical frame rod 2 via mounting plate 301, and the U-shaped structure on the upper frame rods 3... The mounting plate 601 and the connecting rod 602 support the hanging rope wheel 6, which is connected to the car via a steel wire rope to achieve force transmission between the counterweight and the car. The bottom of the vertical frame rod 2 is fixed to the base plate 4 via the mounting plate 401. The base plate 4 provides a bearing foundation for the counterweight 503, and the counterweight 503 is embedded inside the vertical frame rod 2 to form a longitudinal sliding limit, preventing the counterweight from shifting laterally. A pressure-reducing groove 201 is opened on the side of the vertical frame rod 2 near the guide wheel frame 1 to disperse the lateral force transmitted by the guide wheel frame and reduce stress concentration at the connection point. The limiting hole 202 on the vertical frame rod 2 fixes the position of the side plate 501 and the side plate 502 to ensure that the pressure member 5 forms a stable top limit on the counterweight 503, preventing the counterweight from shifting during lifting and lowering.

[0023] Secondly, the wide pulley 104, narrow pulley 105, and side pulley 106 on the guide wheel frame 1 constitute a "three-point three-dimensional buffer guide system." The core of this system is to achieve dynamic adaptation to the guide rail through "multi-pulley coordination + elastic deformation + low-friction rotation." The wide pulley 104 is connected to the guide wheel frame 1 via a connecting rod 101, which passes through the bearing inside the wide pulley. When the counterweight system moves up and down along the guide rail, the wide pulley 104 rolls against the lateral surface of the guide rail. The two sets of side pulleys 106 are movably connected to the side mounting rod 102 via a snap-fit ​​103, and the side mounting rod 102 passes through the bearing inside the narrow pulley 105. The side pulleys 106 conform to the vertical surfaces on both sides of the guide rail, forming "bidirectional left and right limiting" to prevent the counterweight system from lateral swinging.

[0024] Then, the counterweight 503 and the guide wheel assembly form a "load balance + stable guidance" linkage mechanism to ensure that the counterweight system operates smoothly and synchronously with the car. The pressure member 5 is fixed to the vertical frame rod 2 through side plate 1 501 and side plate 2 502. By adjusting the preload of the pressure member, it can be ensured that the counterweight 503 fits tightly with the base plate 4, avoiding intermittent vibration when the counterweight is raised or lowered. The rope wheel 6 is connected to the upper frame rod 3 through connecting rod 2 602. One end of the wire rope is wrapped around the rope wheel 6, and the other end is connected to the car. When the car is raised or lowered, the wire rope drives the rope wheel 6 to rotate, thereby pulling the counterweight system to rise and fall synchronously along the guide rail. At this time, the wide pulley and side pulley of the guide wheel assembly adapt to the state of the guide rail in real time, providing stable guidance for the counterweight system.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
