Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, specifically to an elevator counterweight compensator. Background Technology

[0002] Elevators, as core equipment for vertical transportation, are widely used in various buildings, such as residential buildings, commercial buildings, and industrial plants, providing great convenience for people's daily travel and goods handling, and greatly improving the building's utilization efficiency and space value. They operate based on traction drive, and the counterweight balances the weight of the car and reduces the load on the traction machine.

[0003] Chinese patent CN218231481U discloses an elevator counterweight balancing device. This counterweight device is threadedly connected to a connecting column via a support ring to support a counterweight plate. Several counterweight plates are respectively set on the side wall of the connecting component via several support rings. Each counterweight plate is individually connected to the connecting column, improving the safety of the device. A groove for accommodating the support ring is opened in the middle of the bottom end of the counterweight plate. During installation, the support ring is embedded in the groove of the corresponding counterweight plate, reducing the overall space occupied by the counterweight component. During installation, the counterweight plate is placed in the receiving chamber, ensuring stability.

[0004] In the above-mentioned device, several counterweight plates are threaded onto the connecting columns. On the one hand, the assembly efficiency is low, and it is difficult to control the height of the connecting columns with threaded connections. There is a height difference between the two connecting columns, which affects the uniformity of force distribution and increases safety hazards. On the other hand, when the counterweight needs to be adjusted later, the connecting columns need to be rotated to add or remove counterweight plates. However, the top of the connecting column is connected to the traction rope, and directly rotating the connecting column will have an adverse effect on the use of the traction rope, making the adjustment of the counterweight plates very inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide an elevator counterweight compensator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] An elevator counterweight compensator includes a top plate and multiple counterweight plates. Lifting rings are installed on both sides of the top of the top plate, and side plates are connected to both sides of the bottom of the top plate. A support plate is installed on the bottom of both side plates, and the multiple counterweight plates are mounted on the support plate. Slots are provided at both ends of each counterweight plate, and the surface of the side plates is provided with a insertion mechanism that engages with the slots.

[0008] Therefore, it is evident that through the interlocking mechanism and slots, even if the support plate breaks, the counterweight plate's counterweight function can still be guaranteed, preventing it from falling and ensuring good safety. Furthermore, the counterweight plate is easy to assemble and disassemble, facilitating future adjustments to its quantity. The two lifting rings remain at a fixed height, preventing uneven force distribution due to height differences.

[0009] Furthermore, the insertion mechanism includes a base plate disposed on the surface of the side plate. Multiple insertion blocks are evenly spaced along the height direction of the base plate surface. Multiple through slots are evenly spaced on the surface of the side plate, and the ends of the insertion blocks pass through the through slots and are inserted into the slots. Inserting the insertion blocks from the base plate through the through slots and into the slots provides secondary support for the counterweight plate.

[0010] Furthermore, fixing blocks are installed at the four corners of the substrate surface, and bolts are mounted on the fixing blocks. The side plate surface has four screw holes that match the bolts. By simply unscrewing the bolts to release the substrate, the number of counterweight plates can be adjusted.

[0011] Furthermore, limit plates are provided on both sides of the side plate surface, with a notch between the top of the limit plate and the bottom of the top plate. This prevents the counterweight plates from falling off the support plate when adding or removing them.

[0012] Furthermore, handles are provided on both the front and back sides of the counterweight plate, offering hand gripping points for easy handling.

[0013] Furthermore, corner plates are installed at the connection between the side panels and the top panel. These plates reinforce the connection, increase the strength of the connection, and reduce the possibility of deformation.

[0014] Furthermore, it also includes two guide rails. Mounting plates are installed at both ends of the top plate, and multiple guide wheels are rotatably mounted on the outer surface of the mounting plates. The outer edges of the guide wheels are set within the guide rails. This serves to limit and guide movement, ensuring stability during lifting and lowering.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] This invention provides basic support for the counterweight plate using a support plate and secondary support by inserting blocks into slots. This ensures that both the support plate and side plates provide support, guaranteeing the counterweight plate's function even if the support plate breaks, preventing it from falling and ensuring good safety. Furthermore, the counterweight plate is easy to assemble and disassemble, facilitating future adjustments to its quantity. The two lifting rings remain at a fixed height, preventing uneven stress due to height differences. Attached Figure Description

[0019] 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.

[0020] like Figure 1-5 As shown, an elevator counterweight compensator includes a top plate 1 and multiple counterweight plates 2. Lifting rings 103 are installed on both sides of the top of the top plate 1, and side plates 101 are connected to both sides of the bottom of the top plate 1. A support plate 102 is installed on the bottom of both side plates 101, and the multiple counterweight plates 2 are mounted on the support plate 102. Slots 201 are provided at both ends of each counterweight plate 2, and a insertion mechanism 3 is provided on the surface of the side plates 101 to engage with the slots 201.

[0021] In use, first, according to the counterweight requirements, place an appropriate number of counterweight plates 2 on the support plate 102. Then, use the insertion mechanism 3 to connect with the slot 201 to support and fix the counterweight plates 2 from the side. Next, connect the traction rope to the lifting ring 103. The support plate 102 provides basic support for the counterweight plates 2, and the insertion mechanism 3 provides secondary support for the counterweight plates 2. Thus, both the support plate 102 and the side plate 101 play a supporting role. Even if the support plate 102 breaks, the counterweight function of the counterweight plates 2 can still be guaranteed, preventing them from falling and ensuring good safety.

[0022] Furthermore, the counterweight plate 2 is easy to assemble and disassemble. Simply disconnect the insertion mechanism 3 from the slot 201, and the number of counterweight plates 2 can be adjusted. During adjustment, the traction rope remains connected to the lifting ring 103, which does not affect the elevator's operation, making it very convenient. Also, the two lifting rings 103 are always at a fixed height, preventing uneven force distribution due to height differences.

[0023] Preferably, the insertion mechanism 3 includes a base plate 301 disposed on the surface of the side plate 101. A plurality of insertion blocks 302 are installed at equal intervals along the height direction on the surface of the base plate 301. A plurality of through slots 303 are opened at equal intervals on the surface of the side plate 101. The ends of the insertion blocks 302 pass through the through slots 303 and are inserted into the slots 201.

[0024] After the counterweight plate 2 is placed on the support plate 102, the insert block 302 on the base plate 301 passes through the through groove 303 and is inserted into the slot 201. At this time, it can provide secondary support for the counterweight plate 2. When the support plate 102 breaks, the insert block 302 can still support the counterweight plate 2 to prevent it from falling, which is safe.

[0025] Preferably, a fixing block 304 is installed at each of the four corners of the surface of the substrate 301, and a bolt 305 is installed on the fixing block 304. The surface of the side plate 101 is provided with four screw holes that are compatible with the bolts 305.

[0026] The connection method of bolt 305 ensures that the insert 302 can be stably inserted into the slot 201, which is safe. When increasing or decreasing the number of counterweight plates 2, simply unscrew the bolt 305 to release the fixation of the base plate 301, and then pull the insert 302 out of the slot 201 to adjust the number of counterweight plates 2 at will. The operation is simple.

[0027] Preferably, a limiting plate 4 is provided on both sides of the surface of the side plate 101, and a notch 401 is provided between the top of the limiting plate 4 and the bottom of the top plate 1.

[0028] When adding or removing the counterweight plate 2, the insert block 302 needs to be pulled out of the slot 201 first. At this time, the limit plates 4 on both sides can play a limiting role to prevent the counterweight plate 2 from falling off the support plate 102. The counterweight plate 2 can be added or removed through the notch 401.

[0029] Furthermore, the limiting plate 4 ensures that the slot 201 can accurately correspond to the plug 302, thereby improving the insertion efficiency.

[0030] Preferably, handles 202 are provided on both the front and rear sides of the counterweight plate 2.

[0031] The handle 202 provides a hand gripping point for easy picking up.

[0032] Preferably, a corner plate 6 is provided at the connection between the side plate 101 and the top plate 1.

[0033] The corner plate 6 provides reinforcement at the connection between the side plate 101 and the top plate 1, improving the connection strength and reducing the possibility of deformation.

[0034] Preferably, it also includes two guide rails 5. Mounting plates 501 are installed at both ends of the top plate 1, and multiple guide wheels 502 are rotatably mounted on the outer surface of the mounting plates 501. The outer edges of the guide wheels 502 are set inside the guide rails 5.

[0035] The guide rail 5 is installed on the inner wall of the elevator shaft. When the top plate 1 is raised or lowered, it drives the guide wheel 502 to roll on the guide rail 5, which can play a role in limiting and guiding, and ensure the stability during the raising and lowering process.
