Abstract
Description
Technical Field
[0001] This utility model relates to elevator equipment, and more specifically, to a counterweight anti-jump device. Background Technology
[0002] Currently, elevators in industrial parks typically have large load capacities, resulting in long and heavy counterweights. This presents significant challenges for the installation of elevator counterweights. Current counterweights are secured by top rods on the side beams of the elevator frame. However, the pressure exerted by these top rods is not reliable enough to secure the counterweights. Furthermore, the small contact area between the top rods and the counterweight results in very high pressure at the contact point, easily crushing the surface of the concrete counterweight. This leads to loosening at the contact point between the top rods and the counterweight, preventing reliable fixation. Loosening causes the counterweights to bounce, affecting the normal operation of the elevator.
[0003] Therefore, a new solution is needed to address this problem. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a counterweight anti-jump device.

[0006] A counterweight anti-jump device includes a lower counterweight beam, two side counterweight beams, and several counterweights. The two side counterweight beams are fixedly connected to both ends of the lower counterweight beam. A vertically oriented limiting groove is provided on one side of the two side counterweight beams. Each counterweight is stacked on the lower counterweight beam, and a portion of the counterweight is embedded in the limiting groove of the side counterweight beam. The device also includes two anti-jump plates, which press against the upper part of the uppermost counterweight, and both sides of the anti-jump plates are fixedly connected to the side counterweight beams on both sides.

[0012] The present invention is further configured such that the anti-jump plate abuts against the outer side of the side guard, and the clamping mechanism includes a clamping block, a pad block and a bolt component two. The clamping block is located on the inner side of the side guard, the pad block is located on the outer side of the anti-jump plate, and the bolt component two penetrates through the anti-jump plate, thereby locking the clamping block and the pad block. The anti-jump plate and the side guard can be press-fitted and fixed between the clamping block and the pad block.
[0013] The present invention is further configured such that the clamping block includes a clamping part one and a clamping part two, the clamping part one abuts against the anti-jump plate, the clamping part two forms a clamping gap with the anti-jump plate, and the side guard extends into the clamping gap to achieve clamping and fixing.

[0016] In summary, this utility model has the following beneficial effects:
[0017] By employing two anti-slip plates, the upper part of the counterweight can be pressed and limited. The large contact area between the anti-slip plates and the counterweight ensures the stability of the counterweight during installation. Furthermore, the anti-slip plates are connected and fixed to the side beams of the counterweight frame via a clamping mechanism located at the end of the anti-slip plates. The clamping mechanism and the side edge of the counterweight frame side beam can slide up and down relative to each other for adjustment, eliminating the need for pre-drilling holes in the side beams and facilitating fixing at different positions. The bolted connection eliminates the need for welding, making installation convenient and quick. Attached Figure Description

[0023] 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.
[0024] This embodiment discloses a counterweight anti-jump device, including a lower counterweight beam 2, two side counterweight beams 1, several counterweights 4, and two anti-jump plates 3. The two side counterweight beams 1 are fixedly connected to both ends of the lower counterweight beam 2, and vertically oriented limiting grooves 11 are provided on opposite sides of the two side counterweight beams 1. The counterweights 4 are stacked on the lower counterweight beam 2, with parts of the counterweights 4 embedded in the limiting grooves 11 of the side counterweight beams 1. The limiting grooves 11 can effectively limit the lateral movement of the counterweights 4, maintaining their horizontal position in a stable state.
[0025] Two anti-skid plates 3 press against the upper part of the uppermost counterweight 4, and the two sides of the anti-skid plates 3 are fixedly connected to the side beams 1 of the counterweight frame on both sides. The two anti-skid plates 3 can press and limit the upper part of the counterweight 4, and the lower side of the anti-skid plates 3 presses against the counterweight 4. The pressing position between the two is a surface-to-surface structure, which can reduce the pressure at the pressing position, maintain a stable pressing and clamping state, and keep the upper and lower positions of the counterweight 4 stable.
[0026] Reference Figure 2 , Figure 3 As shown, the counterweight 4 includes two limiting parts 41 and two pressing parts 42. The two limiting parts 41 and the two pressing parts 42 are respectively located at the four edges of the outer periphery of the counterweight 4, and the two limiting parts 41 are arranged opposite to each other, and the two pressing parts 42 are also arranged opposite to each other.
[0027] The size of the limiting part 41 is adapted to the limiting groove 11, and it can be embedded in the limiting groove 11 of the counterweight frame side beam 1. It can also be adjusted up and down in the limiting groove 11, so that the counterweight block 4 can be placed downward along the limiting groove 11 of the counterweight frame side beam 1. The two pressing parts 42 are located on the lower side of the anti-jump plate 3. The anti-jump plate 3 abuts against the pressing part 42 of the uppermost counterweight block 4. The anti-jump plate 3 presses and blocks from above, which can keep the counterweight block 4 stably installed.
[0028] Reference Figure 1 , Figure 2 As shown, a middle clamping plate 5 is also installed between the two anti-jumping boards 3. The middle clamping plate 5 is located approximately in the middle of the anti-jumping board 3, and its two sides are connected and fixed to the two anti-jumping boards 3 respectively. The middle clamping plate 5 can connect and fix the two anti-jumping boards 3 to form a whole, thereby ensuring the stability of the two anti-jumping boards 3 and helping to increase their strength.
[0029] Specifically, connecting parts 51 are fixedly connected to both sides of the intermediate clamping plate 5, and the connecting parts 51 are fixedly connected to the anti-slip plates 3 on both sides by bolts 6. Furthermore, the lower side of the intermediate clamping plate 5 is relatively flush with the lower side of the anti-slip plate 3, and the lower sides of the anti-slip plate 3 and the intermediate clamping plate 5 can jointly abut against the upper part of the counterweight 4. The lower side of the intermediate clamping plate 5 can also abut against the upper part of the uppermost counterweight 4, which can form additional pressure points between the anti-slip plates 3, further increasing the installation stability of the counterweight 4.
[0030] Reference Figure 2 As shown, each of the two counterweight side beams 1 has two side guards 12 fixedly connected to one side of its opposite side, and a limiting groove 11 is formed between the two side guards 12. Specifically, the cross-section of the counterweight side beam 1 is I-shaped.
[0031] The anti-skid plate 3 is connected and fixed to the side guard 12 of the counterweight frame side beam 1 by a clamping mechanism 7, and the fixed position can be adjusted up and down along the side guard 12. There are four sets of clamping mechanisms 7, which can connect and fix two anti-skid plates 3 and two counterweight frame side beams 1, and the four sets of clamping mechanisms 7 are located at the four corners.
[0032] Reference Figure 4 As shown, the anti-jump plate 3 abuts against the outer side of the side guard 12. The clamping mechanism 7 includes a clamping block 71, a pad 72, and a bolt 73. The clamping block 71 is located inside the side guard 12, and the pad 72 is located outside the anti-jump plate 3. The bolt 73 penetrates the anti-jump plate 3 and can lock the clamping block 71 and the pad 72. The anti-jump plate 3 and the side guard 12 can be press-fitted and fixed between the clamping block 71 and the pad 72. By tightening the bolt 73, the clamping connection can be locked and fixed.
[0033] The clamping block 71 includes a first clamping part 711 and a second clamping part 712. The first clamping part 711 abuts against the anti-jump plate 3, and the second clamping part 712 forms a clamping gap 713 with the anti-jump plate 3. During installation, the side guard 12 extends into the clamping gap 713 to achieve clamping and fixation. The clamping mechanism 7 can adjust up and down with the anti-jump plate 3. During the adjustment process, the side guard 12 can be within the clamping gap 713, and the two can form an adaptive up and down adjustment movement.
[0034] To facilitate the installation of bolt component 73, a through hole 31 is provided on the anti-skid plate 3 corresponding to the clamping mechanism 7. Bolt component 73 passes through the through hole 31, and the screw head and nut at both ends of bolt component 73 are respectively located at the two ends to form a limit. The through hole 31 is specifically a slotted hole, and its direction is set in the transverse direction. Bolt component 73 and clamping mechanism 7 can be adjusted in the transverse direction along the through hole 31. By adjusting, the depth of the side guard 12 extending into the clamping gap 713 can be adjusted, so that the clamping mechanism 7 can stably and effectively clamp and fix the side guard 12, ensuring that the clamping mechanism 7 can connect and fix the anti-skid plate 3 and the counterweight side beam 1. By clamping, each counterweight block 4 can be stably installed.
[0035] During installation, the counterweight blocks 4 are first stacked on the lower beam 2 of the counterweight frame, and the two anti-slip plates 3 are placed on the uppermost counterweight block 4. The middle clamping plate 5 and the anti-slip plates 3 are connected with hexagonal bolts. At this time, the anti-slip plates 3 are attached to the side beam 1 of the counterweight frame. The clamping mechanism 7 is installed at the end of the anti-slip plate 3. The bolt part 73 is passed through the clamping block 71 and the pad 72. The side guard 12 of the side beam 1 of the counterweight frame is embedded into the clamping gap 713 and extends into the clamping mechanism 7. The bolt part 73 is tightened, and the side guard 12 of the side beam 1 of the counterweight frame is clamped and fixed to the anti-slip plate 3 through the clamping mechanism 7. In addition, the remaining three clamping mechanisms 7 are also locked and fixed, which can realize the connection and fixation of the two sets of anti-slip plates 3 to the two sets of side beams 1 of the counterweight frame. The device is assembled as a whole, without welding or drilling holes in the side beam 1 of the counterweight frame, making the installation convenient and quick.
