Description

Technical Field

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

[0002] The counterweight frame is a structure used in elevator systems to install counterweight blocks. When installing the counterweight blocks onto the counterweight frame, since the counterweight frame is already installed on the elevator guide rail, and the distance between the two slots on the counterweight frame is fixed, it is necessary to control the counterweight blocks to be tilted when inserting them into the slots. As the placement height increases, the difficulty of inserting the counterweight blocks also gradually increases. At the same time, after the counterweight blocks are placed, the two ends of the counterweight blocks cannot simultaneously contact the two inner surfaces of the slots, causing the counterweight blocks to move between the two slots and generate noise. Utility Model Content

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

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The novel counterweight frame structure includes a base frame, with upright frames at both ends of the base frame, and top plates for connecting the two upright frames on both sides of the upper end of the upright frames. A fixing groove is provided on the base frame and on one side of one of the upright frames, the fixing groove being fixedly connected to the base frame and the top plate. The structure also includes a movable groove. A fixing plate is provided on the base frame and between the two top plates. The other upright frame is connected to the fixing plate via a fixing rod. Both ends of the movable groove are slidably connected to the fixing rod. A bolt is threaded onto the upright frame, the tail end of which is rotatably connected to the movable groove. The structure also includes a limiting frame, which is connected to the fixing groove and the movable groove via fasteners.

[0005] Preferably, a spring is fitted onto the fixed rod, and the spring is located between the movable groove and the upright frame.

[0006] Preferably, a sleeve is provided on the inner side of the movable groove, and the fixed rod is slidably connected to the sleeve.

[0007] Preferably, the inner side of the upright frame is provided with a reinforcing cylinder, and the reinforcing cylinder is provided with a threaded hole that mates with a bolt.

[0008] Preferably, the limiting frame has an elastic pad inside, and the pad is in a compressed state when the limiting frame is fixed to the movable groove and the fixed groove by fasteners.

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

[0010] When installing the counterweight, the counterweight frame increases the distance between the movable slot and the fixed slot, thus facilitating the installation of the counterweight. After the counterweight is installed, by controlling the movable slot, the counterweight is positioned between the movable slot and the fixed slot, and both ends of the counterweight can contact the fixed slot and the movable slot respectively. Therefore, the noise caused by the counterweight moving between the movable slot and the fixed slot can be reduced. Attached Figure Description

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

[0016] like Figure 1-3 As shown, a novel counterweight frame structure includes a base frame 1, with upright frames 2 at both ends of the base frame 1. Top plates 3 for connecting the two upright frames 2 are respectively provided on the upper sides of the upright frames 2. A fixing groove 4 is provided on the base frame 1 and on one side of one of the upright frames 2. The fixing groove 4 is fixedly connected to the base frame 1 and the top plate 3. The structure also includes a movable groove 15. Fixing plates 5 are respectively provided on the base frame 1 and between the two top plates 3. The other upright frame 2 is connected to the fixing plate 5 by a fixing rod 6. The two ends of the movable groove 15 are slidably connected to the fixing rod 6. Bolts 7 are threadedly connected to the upright frame 2. The tail end of the bolts 7 is rotatably connected to the movable groove 15. The structure also includes a limiting frame 8, which is connected to the fixing groove 4 and the movable groove 15 by fasteners 9.

[0017] When installing the counterweight 14, first install the counterweight frame onto the elevator guide rail frame. Then, rotate bolt 7. Since bolt 7 is threaded to the vertical frame 2 and its tail end is rotatably connected to the movable slot 15, as bolt 7 is unscrewed from the vertical frame 2, the movable slot 15 will move along the fixed rod 6, increasing the distance between the movable slot 15 and the fixed slot 4. This increased distance facilitates the placement of the counterweight 14 between the movable slot 15 and the fixed slot 4. The counterweight 14 can then be placed horizontally between the movable slot 15 and the fixed slot 4, with one end of the counterweight 14 entering the fixed slot 4. Then, the counterweight 14 is stacked upwards sequentially. The process continues until all counterweights 14 are placed. After the counterweights 14 are placed, the control bolt 7 is rotated in the opposite direction, pushing the movable groove 15 towards the fixed groove 4. As the distance between the movable groove 15 and the fixed groove 4 decreases, one end of the counterweight 14 will enter the movable groove 15. When the movable groove 15 comes into contact with the counterweight 14, it can no longer be pushed to move. At this point, the adjustment of the movable groove 15 is completed, the rotation of the bolt 7 is stopped, and then the limiting frame 8 is placed on the uppermost counterweight 14. The limiting frame 8 is installed on the movable groove 15 and the fixed groove 4 through the fastener 9 and the through holes reserved on the movable groove 15 and the fixed groove 4, thereby stably limiting the counterweight 14 on the counterweight frame.

[0018] The positions of the through holes opened in the movable groove 15 and the fixed groove 4 correspond to the number of counterweights 14. That is, after the rated number of counterweights 14 are placed, and when the limiting frame 8 is placed on the uppermost counterweight 14, the position of the through hole corresponds exactly to the position of the limiting frame 8, so that the limiting frame 8 can be fixed to the fixed groove 4 and the movable groove 15 by fasteners 9. If there is an error in the position of the through hole, it can be solved by opening new through holes later.

[0019] Because the counterweight frame uses two upright frames 2, a movable slot 15, and a fixed slot 4, and all four components can be connected to the base frame 1 simultaneously, the stability of the base frame 1 is increased. This avoids the problem of the upright frames 2 and the base frame 1 breaking or failing to connect due to impact when the existing counterweight frame is subjected to an impact. It ensures that the base frame 1 can effectively support the counterweight block 14 above, preventing the counterweight block 14 from falling down from the base frame 1. At the same time, the weight of the counterweight block 14 used in this counterweight frame is less than that of a conventional counterweight block 14, making it easier for workers to handle and install. Only a larger number of counterweight blocks 14 are needed to meet the counterweight requirements.

[0020] Furthermore, a spring 10 is fitted onto the fixed rod 6, and the spring 10 is located between the movable groove 15 and the upright frame 2 to improve the stability and smoothness of the movable groove 15 during movement.

[0021] Furthermore, a sleeve 11 is provided on the inner side of the movable groove 15, and the fixed rod 6 is slidably connected to the sleeve 11, which further improves the stability and smoothness of the movable groove 15 when it moves.

[0022] Furthermore, a reinforcing cylinder 12 is provided on the inner side of the upright frame 2, and the reinforcing cylinder 12 is provided with a threaded hole that mates with the bolt 7, thereby improving the stability of the bolt 7 when it rotates on the upright frame 2.

[0023] Furthermore, the limiting frame 8 is provided with an elastic pad 13 inside. When the limiting frame 8 is fixed to the movable groove 15 and the fixed groove 4 by the fastener 9, the pad 13 is in a compressed state, so that the counterweight block 14 on the counterweight frame can fit together tightly, thereby avoiding friction noise caused by movement.

[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.
