Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight technology, and more specifically, to an anti-loosening device for elevator counterweight blocks. Background Technology

[0002] In elevator systems, counterweights are key components for balancing the weight of the car, and their stability directly affects the safety and comfort of elevator operation. Traditionally, counterweights are stacked in a counterweight frame, but this presents some problems:

[0003] Traditionally, counterweights are mostly stacked by gravity. During long-term elevator operation (such as frequent starts and stops, vibrations), the counterweights are prone to horizontal displacement due to inertia, resulting in loosening, misalignment, or collision with the counterweight frame, causing abnormal noises or even structural damage. Therefore, we have made an improvement and proposed an elevator counterweight anti-loosening device. Utility Model Content

[0004] The purpose of this invention is to address the problem that counterweights are prone to horizontal displacement due to inertia, resulting in loosening.

[0005] In order to achieve the above-mentioned objectives, this utility model provides an elevator counterweight anti-loosening device to improve the above-mentioned problems.

[0006] The application is as follows:

[0007] An elevator counterweight anti-loosening device includes a counterweight frame body, a plurality of counterweight blocks are arranged inside the counterweight frame body, slots are provided on both sides of the plurality of counterweight blocks, baffles are provided on both sides of the counterweight frame body, and a plurality of limiting plates are fixedly connected to the side of two baffles that are close to each other, and the outer surface of the limiting plates is inserted into the slots.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] For an example, please refer to... Figures 1-6 An elevator counterweight anti-loosening device includes a counterweight frame body 1, a plurality of counterweight bodies 101 are arranged inside the counterweight frame body 1, slots 102 are provided on both sides of the plurality of counterweight bodies 101, baffles 201 are provided on both sides of the counterweight frame body 1, and a plurality of limiting plates 203 are fixedly connected to the side of the two baffles 201 that are close to each other. The outer surface of the limiting plates 203 is inserted into the slots 102. In this application, by setting baffles 201 and limiting plates 203, after the limiting plates 203 are inserted into the counterweight bodies 101, the baffles 201 can prevent the horizontal and vertical displacement of the counterweight bodies 101, thereby reducing the loosening of the counterweight bodies 101 and improving the stability of the counterweight bodies 101 during operation.

[0032] Furthermore, several second fixing bolts 202 are connected between the two baffles 201 and the counterweight frame body 1. Nuts are provided on the second fixing bolts 202. The baffles 201 can be fixed to the counterweight frame body 1 by the cooperation of the second fixing bolts 202 and the nuts. The baffles 201 can be released by unscrewing the nuts and removing the second fixing bolts 202.

[0033] Furthermore, two limiting members are provided on the main body 1 of the counterweight frame, and the limiting members are in contact with the top of the uppermost counterweight block body 101. The limiting members can further limit the counterweight block body 101 and further reduce the possibility of the counterweight block body 101 becoming loose.

[0034] Furthermore, the limiting components include a first clamping plate 3 and a second clamping plate 301 disposed on the counterweight frame body 1. A stop plate 302 is fixedly connected to the bottom of the second clamping plate 301. The stop plate 302 contacts the top of the uppermost counterweight body 101, which can further limit the counterweight body 101 and further reduce the possibility of the counterweight body 101 becoming loose.

[0035] Furthermore, several third fixing bolts 303 are interlaced between the first clamping plate 3 and the second clamping plate 301. Nuts are also provided on the third fixing bolts 303. The third fixing bolts 303 and the nuts cooperate to fix the second clamping plate 301 and the first clamping plate 3 to the counterweight frame body 1, so as to further limit the counterweight block body 101. After unscrewing the nuts, the third fixing bolts 303 can be removed, thereby releasing the fixation of the first clamping plate 3 and the second clamping plate 301.

[0036] Furthermore, multiple limiting holes 304 are provided on the outer side of the main body 1 of the counterweight. A limiting rod 305 is fixedly connected to the first clamping plate 3. The end of the limiting rod 305 is inserted into the inner wall of one of the limiting holes 304. Through the cooperation of the limiting rod 305 and the limiting hole 304, the first clamping plate 3 can be limited, thereby limiting the second clamping plate 301 and the abutment plate 302, preventing the second clamping plate 301 and the abutment plate 302 from moving up and down, thereby improving the limiting effect on the counterweight main body 101.

[0037] Furthermore, the center distance between two adjacent limiting holes 304 is the same as the thickness of the counterweight body 101. That is, after the first clamping plate 3 moves up and down by a distance equal to the thickness of the counterweight body 101, it will align with the limiting hole 304 at the corresponding position, so as to adjust the position of the first clamping plate 3 according to the number of counterweight bodies 101.

[0038] Furthermore, auxiliary components are also provided on the main body 1 of the counterweight.

[0039] Furthermore, the auxiliary components include two notches 103 formed on the main body 1 of the counterweight frame. A guard plate 104 is provided on the main body 1 of the counterweight frame. A first fixing bolt 105 is connected between the guard plate 104 and the main body 1 of the counterweight frame. A nut is also provided on the first fixing bolt 105. After removing the first fixing bolt 105 and the guard plate 104, the main body 101 of the counterweight block can be removed from the notch 103.

[0040] Furthermore, the opening size of the notch 103 is larger than the thickness of the counterweight body 101, so as to facilitate the removal of the counterweight body 101.

[0041] During installation, the counterweight body 101 is placed into the counterweight frame body 1 along the notch 103, and then the guard plate 104 is fixed to the counterweight body 101 by the first fixing bolt 105. The limiting plate 203 is aligned with the slot 102 and inserted. Then, the baffle 201 is fixed by the second fixing bolt 202. Finally, the height of the first clamping plate 3 is adjusted so that the limiting rod 305 is inserted into the corresponding limiting hole 304 and locked by the third fixing bolt 303.
