Description

Technical Field

[0001] The utility model relates to the technical field of guardrail accessories, in particular to a guardrail fixing component for an elevator. Background Art

[0002] As vertical transportation equipment, elevators play a vital role in construction, logistics, and other fields. To ensure the safety of operators, elevators are often equipped with guardrails to prevent people and objects from accidentally falling. With the development of industrial technology, higher requirements are being placed on the safety, flexibility, and ease of operation of elevators.

[0003] Currently, most elevator guardrail mounting components on the market utilize fixed connections, such as bolts or welding. This design requires disassembly of the guardrail for loading and unloading oversized cargo or transporting personnel, a cumbersome and time-consuming process. Furthermore, while some elevator guardrails are designed to be removable or foldable, their structural design is inefficient, making the disassembly and folding process complex and impacting work efficiency.

[0004] The guardrail fixing assembly of the prior art mainly has the following defects:

[0005] Inflexible fixing: The fixing method is single and cannot be quickly adapted to different usage scenarios. In particular, when the guardrail needs to be quickly disassembled in an emergency, the existing design cannot meet the needs.

[0006] Difficulty in disassembly and installation: The disassembly and installation process of the guardrail is complicated and requires professional operation, which increases labor costs and time costs. In addition, frequent disassembly and installation may cause damage to the guardrail fixing components, affecting the service life.

[0007] Insufficient safety: The mechanical strength of some elevator guardrail fixing components is insufficient, and they are prone to deformation or damage during use, posing a safety hazard. Summary of the Invention

[0008] The purpose of the present utility model is to provide an elevator guardrail fixing assembly to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned object, the present invention provides the following technical solution: an elevator guardrail fixing assembly, comprising a main cable, wherein the lower end of the main cable is fixedly connected to a connecting plate, the lower end of the connecting plate is annularly fixedly connected to a plurality of traction ropes, one end of the plurality of traction ropes away from the connecting plate is commonly fixedly connected to a frame, and the inner surface of the frame is annularly provided with a plurality of fixing fasteners;

[0010] Preferably, the fixing fastener includes a support member fixedly connected to the inner surface of the frame, a compression member is provided on the upper inner surface of the support member, and locking members connected to the compression member are symmetrically provided on the left and right sides of the inner surface of the support member.

[0011] Preferably, the support member includes a support frame fixedly connected to the inner surface of the skeleton, the top of the support frame is horizontal and the bottom is an L-shaped block with two vertical sides relatively distributed, a limiting groove 1 is symmetrically provided on the inner surface of the support frame, and a limiting groove 2 is symmetrically provided on the inner surfaces of the two limiting grooves 1.

[0012] Preferably, the first limiting groove and the second limiting groove are both L-shaped, and the intersection of the vertical part and the horizontal part thereof is a smooth arc track.

[0013] Preferably, the compression member includes a compression block, the upper end of the compression block is symmetrically fixedly connected to a limiting rod, the outer surfaces of the two limiting rods are slidably connected to a base plate, the end of the base plate opposite to the telescopic lever is jointly fixedly connected to two compression springs sleeved on the outer surfaces of adjacent limiting rods, and the upper end of the base plate is symmetrically fixedly connected to a limiting plate fixedly connected to the top wall of the inner surface of the support frame.

[0014] Preferably, the opposite ends of the two limit plates are rotatably connected to telescopic levers that are symmetrically distributed on the left and right. The two telescopic levers are provided with a buffer groove that passes through the front and back on the side close to the limit rod. The limit rod is slidably connected to the inner surface of the buffer groove. The ends of the two telescopic levers away from the limit rod on the same side are rotatably connected to a T-shaped slider that is slidably connected to the inner surface of the limit groove on the same side. The lower ends of the two T-shaped sliders are rotatably connected to the locking piece on the same side.

[0015] Preferably, the locking member includes a plurality of chain links distributed along the path curve of the limiting groove 1, and two adjacent chain links are rotatably connected to each other. The front and rear sides of the chain links are slidably connected to the inner surface of the limiting groove 2 through pulleys. The chain link on the side away from the T-shaped slider 1 is rotatably connected to the T-shaped slider 2 which is slidably connected to the horizontal part of the limiting groove 1, and the upper end of the T-shaped slider 2 is fixedly connected to a locking block.

[0017] Preferably, the inner cavity of the locking block is provided with a limit spring fixedly connected to the side positioning plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The elevator guardrail fixing assembly drives the limit rod to rise through the interaction between the compression block and the upper part of the guardrail, and promotes the telescopic lever to rotate around the rotation axis between it and the limit plate through the interaction between the limit rod and the telescopic lever, thereby driving the T-shaped slider to slide downward along the limit groove. During this process, the chain buckle will gradually transmit the force to the locking block, thereby pushing the locking block inward at the upper part of the guardrail, and thereby clamping at the lower part of the guardrail to fix the guardrail inside the frame; at the same time, the chain buckle and the connecting rod cooperate to push the connecting rod to the edge of the guardrail, positioning the guardrail from both sides to avoid dislocation of the guardrail in the frame that affects the fixing effect, thereby further improving the stability of the fixation.

[0020] 2. The elevator guardrail fixing component lifts the frame upward after the guardrail falls to the ground. At this time, due to the buffering effect of the compression spring, the pressure block continues to fit with the upper end of the guardrail, but the distance between the limit rod and the base plate will change. During this process, the lever formed by the telescopic lever will pull the T-shaped slider to move upward along the base plate. The locking block is gradually pulled back by the chain buckle and the T-shaped slider and disengaged from the edge of the guardrail, simplifying the dismantling process.

The two telescopic levers 523 are provided with a buffer groove 524 that passes through the front and back on the side close to the limit rod 527. The limit rod 527 is slidably connected to the inner surface of the buffer groove 524. The ends of the two telescopic levers 523 away from the limit rod 527 on the same side are rotatably connected to a T-shaped slider 525 that is slidably connected to the inner surface of the limit groove 512 on the same side.
