Description

Technical Field

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

[0002] The counterweight is located inside the hoistway and is connected to the car via traction ropes and a traction sheave. During elevator operation, the counterweight slides on the counterweight guide rails via counterweight guide shoes, providing balance. The counterweight consists of two parts: the counterweight frame and the counterweight blocks.

[0003] The existing counterweight frame mainly consists of a base frame, vertical frames, and a top plate. The base frame and vertical frames are connected by bolts or rivets. Since the weight of the counterweight is entirely on the base frame, the connection between the base frame and the vertical frames is subjected to a large amount of pressure. When abnormal situations occur, such as the counterweight frame falling rapidly and the buffer component located at the lower end of the counterweight frame colliding with the buffer seat, the reaction force of the collision and the counterweight will squeeze the base frame, which can easily lead to the failure of the connection between the base frame and the vertical frames. Utility Model Content

[0004] The purpose of this invention is to provide a novel counterweight frame structure, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The novel counterweight frame structure includes a base frame, upright frames disposed on both sides of the upper end of the base frame, and a top plate. The upright frames include an expansion section and storage sections disposed at both ends of the expansion section. The base frame is fixedly connected to the storage section below the expansion section, and the top plate is fixedly connected to the storage section above the expansion section. It also includes several support components disposed within the expansion section. The support components provide support and limit the counterweight. The number of support components within a single expansion section is greater than the number of counterweights. Each support component includes a right-angled support plate. The support plate has a bottom surface and a side surface. The distance between the two side surfaces of two support plates at the same horizontal height is equal to the distance between the inner side surfaces of the two storage sections. Two studs are disposed on one side of the support plate. A through hole is provided on the outer surface of the expansion section for the studs to pass through. Nuts are threaded onto the studs.

[0006] Preferably, the support plate is made of rubber, and a steel support frame is provided inside the support plate.

[0007] Preferably, it also includes several wedge-shaped pads, the pads being made of rubber, and the pads having a steel core plate inside.

[0008] Preferably, a buffer is provided on the lower surface of the bottom frame.

[0009] Preferably, the number of support components in a single expansion section is one more than the number of counterweights in the expansion section, and the inner side of the uppermost support plate is provided with reinforcing ribs.

[0010] The beneficial effects of this utility model are:

[0011] When this type of counterweight frame is in use, only a portion of the counterweight weight is placed on the bottom frame, while the remaining counterweight weight is placed on the vertical frame via support plates. When the buffer under the bottom frame collides with the buffer seat below the elevator shaft, the impact of the reaction force during the collision and the weight of the counterweight on the bottom frame is significantly reduced because the weight of the counterweight on the bottom frame is relatively small compared to the existing bottom frame. This also reduces the impact at the connection between the bottom frame and the vertical frame, avoiding the problem of connection failure between the bottom frame and the vertical frame.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-4As shown, a novel counterweight frame structure includes a base frame 1, upright frames 2 disposed on both sides of the upper end of the base frame 1, and a top plate 3. The upright frames 2 include an expansion section 201 and storage sections 202 disposed at both ends of the expansion section 201. The base frame 1 is fixedly connected to the storage section 202 below the expansion section 201, and the top plate 3 is fixedly connected to the storage section 202 above the expansion section 201. It also includes several support components disposed within the expansion section 201. The support components provide support and limit the counterweight 4. The number of support components in a single expansion section 201 is greater than the number of counterweight 4. The support components include right-angled support plates 5. The support plates 5 have a bottom surface 6 and side surfaces 7. The distance between the two side surfaces 7 of two support plates 5 located at the same horizontal height is equal to the distance between the inner side surfaces 7 of the two storage sections 202. Two studs 8 are disposed on one side of the support plate 5. Through holes for the studs 8 to pass through are opened on the outer surface of the expansion section 201. Nuts 9 are threaded onto the studs 8.

[0019] A portion of the counterweight 4 is placed on the bottom frame 1 and located between the storage sections 202 of the two side upright frames 2. The weight of this portion of the counterweight 4 mainly acts on the bottom frame 1. Since not all of the counterweight 4 acts on the bottom frame 1, the pressure at the connection between the bottom frame 1 and the upright frame 2 can be reduced. The bottom frame 1 and the upright frame 2 can be connected by bolts or by riveting.

[0020] The remaining counterweights 4 need to be installed sequentially into the expansion section 201 on the frame 2. Specifically, first, place a support plate 5 in each of the two receiving sections and fix the support plate 5 to the expansion section 201 by threading the nut 9 to the stud 8. After fixing the support plate 5, place a single counterweight 4 on the two support plates 5. Then, place two more support plates 5 on each side above the counterweight 4 and fix the support plates 5 back to the expansion section 201. Then, place the counterweights 4 again until all the counterweights 4 are installed. After all the counterweights 4 have been installed on the expansion section 201, support plates 5 are placed on both sides of the upper surface of the top counterweight 4 and fixed to the expansion section 201 to limit the position of the top counterweight 4. Since the counterweights 4 in this part are placed on the support plates 5 respectively, and the support plates 5 are fixed to the expansion section 201 on the vertical frame 2 by studs 8 and nuts 9, the weight of the counterweights 4 in this part will not act on the bottom frame 1, thereby reducing the pressure at the connection between the bottom frame 1 and the vertical frame 2.

[0021] The counterweight 4 installed in the expansion section 201 has the same specifications as the counterweight 4 installed in the storage section 202, so only counterweight 4 of the same specifications need to be prepared. There is no order in which the counterweight 4 is installed, which improves the convenience of installing the counterweight 4.

[0022] Furthermore, when placing the counterweight 4 between the storage sections 202, the counterweight 4 can be inserted between the two upright frames 2 from the expansion section 201. The expansion section 201 can provide more space for the counterweight 4 to enter between the two upright frames 2, that is, it is not necessary to tilt the counterweight 4 at a larger angle. The counterweight 4 only needs to be tilted at a smaller angle to enter between the two upright frames 2, thereby improving the convenience of installing the counterweight 4.

[0023] For the counterweight 4 placed on the bottom frame 1 and located in the receiving section, the support plate 5 located in the expansion section 201 and at the bottom can restrict the counterweight 4 within the vertical frame 2. The lower surface of the vertical plate abuts against the upper surface of the counterweight 4, which can restrict the movement of the counterweight 4.

[0024] Furthermore, the support plate 5 is made of rubber, and a steel support frame 10 is installed inside the support plate 5, which can reduce the friction noise between the support plate 5 and the counterweight.

[0025] Furthermore, it also includes several wedge-shaped pads 11, which are made of rubber. A steel core plate 12 is installed inside each pad 11. After the counterweights 4 in the receiving section and the expansion section 201 are installed, there is a gap between the uppermost counterweight 4 in the receiving section and the lowermost counterweight 4 in the expansion section 201, and there is also a gap between two adjacent counterweights 4 in the expansion section 201. The height of this gap is equal to the thickness of the support plate 5 after compression. One end of the pad 11 can enter the... Inside the gap, the pad 11 is then struck with a hammer or similar object. The core plate 12 prevents the pad 11 from bending during the strike. During the strike, the pad 11 will enter the gap and be compressed. This improves the installation stability of the counterweight 4, allowing it to be firmly installed on the frame 2. The counterweight 4 is difficult to move on the frame 2, thus avoiding friction noise between the counterweight 4 and the frame 2, the base frame 1, and between the counterweight 4 and the frame 2.

[0026] Furthermore, a buffer 13 is provided on the lower surface of the bottom frame 1.

[0027] Furthermore, the number of support components in a single expansion section 201 is one more than the number of counterweights 4 located in the expansion section 201, and a reinforcing rib 14 is provided on the inner side of the uppermost support plate 5, which can improve the limiting ability of the uppermost support plate 5 to the uppermost counterweight 4.

[0028] 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.
