Description

Technical Field

[0001] This utility model relates to the field of elevator counterweight guardrail technology, and in particular to a reinforced counterweight guardrail. Background Technology

[0002] Elevator counterweight guardrails, such as pit counterweight side guardrails, can effectively isolate the running trajectory of the counterweight device, preventing personnel from accidentally entering under the counterweight during pit operations and avoiding being hit by the moving counterweight. The guardrail is usually installed between the two guide rails in the pit, with a height of 2.5 meters, 0.3 meters from the ground, and a width that covers both sides of the counterweight plus 0.1 meters on each side to ensure the tightness of physical isolation. However, existing elevator counterweight guardrails are usually customized according to the size of the elevator car guide rails, and cannot be adaptively adjusted according to the size of the elevator car guide rails during installation.

[0003] For example, Chinese utility model patent CN221396813U discloses a noise-reducing and easy-to-install counterweight guardrail, which is also the mainstream design of elevator counterweight guardrails on the market. Although this solution can increase the height of the upper part of the guardrail according to the actual required protection height, the guardrail cannot adjust the width of the guardrail for the distance between the two guide rails inside the elevator shaft. This means that a counterweight guardrail often needs to be specially customized according to the elevator shaft of different scenarios, and the installation is very complicated. This is not conducive to the market promotion and standardization of counterweight guardrails.

[0004] In view of this, a reinforced counterweight guardrail that can solve the above problems is proposed. Utility Model Content

[0005] To address the technical challenge of adapting the counterweight guardrail to the width of the elevator track, this invention provides a reinforced counterweight guardrail.

[0006] This utility model is achieved using the following technical solution: a reinforced counterweight guardrail, comprising a reinforcing plate and two guide rails, a reflective sign is provided on one side of the reinforcing plate, multiple sleeves are fixedly connected to both sides of the reinforcing plate, and a second connecting rod is slidably connected to the inner side of each of the multiple sleeves. A fixing plate is fixedly connected to the end of each of the multiple second connecting rods away from the sleeve, and an elevator fixing mechanism is provided on the side of each fixing plate near the guide rail. A positioning rod mechanism is provided between the reinforcing plate and the fixing plates on both sides.

[0007] As a further improvement to the above solution, the elevator fixing mechanism includes multiple connecting plates fixedly connected to the side of each fixing plate near the guide rail. The multiple connecting plates are arranged in a linear array. Each connecting plate has a sliding groove and a running groove on its upper side, and a clamping mechanism is provided on the inner side of each running groove.

[0008] As a further improvement to the above solution, the clamping mechanism includes multiple clamping rods fixedly connected to the guide rails on each side. The multiple clamping rods on the same side are paired with multiple sliding grooves respectively. Each sliding groove has a rotatably connected pliers on its inner side, and the pliers are configured to cooperate with the clamping rods.

[0009] As a further improvement to the above solution, a counterweight is fixedly connected to the upper side of each of the pliers.

[0010] As a further improvement to the above solution, the positioning rod mechanism includes sleeves that are fixedly connected to the upper and lower sides of the reinforcing plate, respectively. A connecting rod is slidably connected to the inner side of each sleeve, and a positioning handwheel mechanism is provided on one side of each sleeve.

[0011] As a further improvement to the above solution, the positioning handwheel mechanism includes a No. 1 handwheel that is threadedly connected to the two sleeve sides at the upper end of the reinforcing plate, and a No. 2 handwheel that is threadedly connected to the lower sides of the two sleeves at the lower end of the reinforcing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model can adjust the distance between the two fixed plates by sliding the multiple No. 2 connecting rods on both sides inward or outward along the inner side of the sleeve. In this way, it can adapt to the installation distance between the two guide rails in the elevator shaft without the need for specific size customization. It achieves the advantage of being able to install and use in elevator shafts of various sizes with just one counterweight guardrail.

[0014] 2. This utility model uses a rotating pliers on a connecting plate. When installing the counterweight guardrail, it pushes the guide rail to one side, causing the locking rod on the guide rail to move along the inside of the groove towards the pliers. Due to the special structure on the outside of the pliers, it can automatically push the pliers open and lock them closed, which has the advantage of convenient installation.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figures 1-3 This embodiment of a reinforced counterweight guardrail includes a reinforcing plate 1 and two guide rails 12. A reflective sign 2 is provided on one side of the reinforcing plate 1. The reflective sign 2 can remind the surrounding staff to maintain a safe distance.

[0024] Please combine Figure 1 As shown, multiple sleeves 3 are fixedly connected to both sides of the reinforcing plate 1, and a second connecting rod 10 is slidably connected to the inner side of the multiple sleeves 3. The width can be adjusted by the insertion and removal distance of the second connecting rod 10 in the sleeve 3.

[0025] Please combine Figure 1 As shown, the ends of multiple second connecting rods 10 on each side away from the sleeve 3 are simultaneously fixedly connected to a fixing plate 4. Each fixing plate 4 is provided with an elevator fixing mechanism on the side near the guide rail 12. A positioning rod mechanism is provided between the reinforcing plate 1 and the fixing plates 4 on both sides.

[0026] Please combine Figure 1 As shown, the elevator fixing mechanism includes three connecting plates 9 fixedly connected to the side of each fixing plate 4 near the guide rail 12. The three connecting plates 9 are arranged in a linear array. Each connecting plate 9 has a sliding groove 16 and a sliding groove 15 on its upper side. The clamping rod 11 can approach the pliers 14 through the sliding groove 15. Each sliding groove 15 has a clamping mechanism on its inner side.

[0027] Please combine Figure 1 As shown, the clamping mechanism includes three clamping rods 11 fixedly connected to each side guide rail 12. The three clamping rods 11 on the same side are paired with multiple sliding grooves 15 respectively. Each sliding groove 16 has a rotatably connected pliers 14 on its inner side. The pliers 14 are configured to cooperate with the clamping rods 11.

[0028] Please combine Figure 4 As shown, each pair of pliers 14 is fixedly connected to a counterweight 8 on its upper side. In this embodiment, the counterweight 8 is a spherical structure.

[0029] Please combine Figure 1 As shown, the positioning rod mechanism includes sleeves 6 that are fixedly connected to the upper and lower ends of the reinforcing plate 1 respectively. A connecting rod 7 is slidably connected to the inner side of each sleeve 6. A positioning handwheel mechanism is provided on one side of each sleeve 6. In this embodiment, the sleeve 6 is a square tube structure.

[0030] Please combine Figure 1 As shown, the positioning handwheel mechanism includes a first handwheel 5 that is threadedly connected to the sides of the two sleeves 6 at the upper end of the reinforcing plate 1, and a second handwheel 13 that is threadedly connected to the lower sides of the two sleeves 6 at the lower end of the reinforcing plate 1.

[0031] The implementation principle of a reinforced counterweight guardrail in this application embodiment is as follows: Before installation, the distance between the two fixed plates 4 is adjusted according to the size of the two guide rails 12 in the elevator shaft. Multiple second connecting rods 10 on each side are pulled to one side along the inside of the sleeve 3. Then, the positions of the upper and lower connecting rods 7 are positioned by the first handwheel 5 and the second handwheel 13 respectively. The distance after positioning is close to the distance between the two guide rails 12. Then, the entire guardrail is pushed towards the clamping rod 11 on the guide rail 12 so that the clamping rod 11 enters the groove 15 on the connecting plate 9. Then, the clamping rod 11 lifts the pliers 14 to rotate and open. When the clamping rod 11 enters the bottom of the groove 15, the pliers 14 close and lock with the cooperation of the counterweight block 8, forming a fixing function for the clamping rod 11.
