Description

Technical Field

[0001] This utility model belongs to the field of elevator car technology, and in particular relates to an assembled protective railing assembly for elevator cars. Background Technology

[0002] The elevator car is the core box-shaped structural component of an elevator system used to carry and transport passengers or goods; it is the transportation space that users directly interact with. Guardrails are important safety devices in the elevator car structure, primarily used to protect the safety of maintenance personnel working on the car top.

[0003] There are many types of guardrail structures on the market. For example, an elevator guardrail with the publication number CN220283220U is disclosed on the China Patent website. This guardrail can be used for the protection of elevator cars, but it has some defects and shortcomings that need to be improved: (1) Most of the existing guardrails adopt a fixed structure, and their protection height is difficult to adjust according to the height and body shape of different maintenance personnel. Moreover, when the guardrail structure is damaged due to long-term use, it is not convenient to disassemble and replace it; (2) Due to the structural design, there is often a certain gap between the bottom of some existing guardrails and the top of the elevator car. When maintenance personnel work on the top of the car, maintenance tools or parts can easily fall through the gap from the top of the elevator car, thus causing safety hazards; (3) Some existing guardrail structures are not rigid enough and lack effective reinforcement measures. When the guardrail is subjected to external force such as collision, it is easy to bend and deform, thus affecting its protective effect and service life. Therefore, in view of the above problems, the assembly guardrail component for elevator cars provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides an assembled safety railing assembly for elevator cars. Through a movable structural design, the height of the safety railing assembly can be adjusted and fixed to protect maintenance personnel of different heights and builds. When the safety railing assembly is damaged due to prolonged use, the individual uprights can be pulled out of the positioning cylinder by unscrewing the screws for disassembly and replacement. The lower baffle effectively fills the gap between the safety railing assembly and the top of the elevator car, preventing maintenance tools or parts from passing through when maintenance personnel are working on the car roof. The gap caused a safety hazard as the guardrail fell through the top of the elevator car. Multiple reinforcing ribs can strengthen the positioning cylinder, increasing its rigidity and preventing bending and deformation under prolonged stress, thus ensuring the stability of the guardrail assembly. Simultaneously, multiple reinforcing blocks can strengthen the lower and upper baffles, improving their resistance to deformation and effectively preventing bending and deformation under impact, thus extending their protective effect and service life. In summary, this solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses an assembly of protective railings for elevator cars, comprising several positioning cylinders. Each positioning cylinder is fixedly connected to the top of the elevator car, and its top wall has a pair of slots. A threaded tube is fixedly connected to the outer wall of the top of each positioning cylinder, and the threaded tube communicates with the inner cavity of the positioning cylinder. A screw is threadedly connected to the inner wall of the threaded tube and engages with it. An upper baffle and a lower baffle are fixedly connected between the outer walls of two adjacent positioning cylinders, respectively. A vertical rod is inserted into each positioning cylinder, and a protrusion is fixedly connected to the top of each vertical rod. Several threaded grooves are formed on the body of each vertical rod, and a handrail is fixedly connected between two adjacent vertical rods.

[0007] Furthermore, the positioning cylinder is cylindrical and located at the four corners of the top surface of the elevator car. The inner diameter of the positioning cylinder is equal to the diameter of the upright, the diameter of the threaded groove is equal to the inner diameter of the threaded tube, and the threaded groove is equidistantly linearly distributed along the axial direction of the upright.

[0008] Furthermore, each of the positioning cylinders has several reinforcing ribs fixedly connected to its bottom outer wall. The reinforcing ribs are triangular in shape, with their bottoms fixedly connected to the top surface of the elevator car, and the reinforcing ribs are distributed in an equidistant ring along the circumference of the positioning cylinder.

[0009] Furthermore, the lower baffle is located below the upper baffle, and the bottom surface of the lower baffle is attached to the top surface of the elevator car.

[0010] Furthermore, the lower baffle and the upper baffle are elongated strips, and the inner surfaces of the lower baffle and the upper baffle are provided with a number of buffer blocks. The surfaces of the buffer blocks are arc-shaped, and the buffer blocks are equidistantly linearly distributed along the length direction of the lower baffle and the upper baffle, respectively.

[0011] Furthermore, a number of reinforcing blocks are fixedly connected between the lower baffle and the upper baffle. The reinforcing blocks are X-shaped and are equidistantly linearly distributed along the length direction of the lower baffle and the upper baffle.

[0012] Furthermore, the diameter of the handrail corresponds to the width of the slot, and each handrail is fitted with an anti-slip sleeve. The inner diameter of the anti-slip sleeve corresponds to the diameter of the handrail, and the surface of the anti-slip sleeve is provided with herringbone anti-slip texture.

[0013] The present invention has the following advantages over the prior art:

[0014] (1) When using the elevator car assembly of the present invention, the height of the assembly can be adjusted and fixed through the movable structure design so that it can protect maintenance personnel of different heights and body types. When the assembly is damaged due to long-term use, each upright can be pulled out from the positioning cylinder by unscrewing the screw so that the assembly can be disassembled and replaced.

[0015] (2) When the elevator car assembly of the present invention is used, the gap between the assembly and the top of the elevator car can be effectively filled by the lower baffle to prevent maintenance tools or parts from falling from the top of the elevator car through the gap when maintenance personnel are working on the car top, thus preventing safety hazards.

[0016] (3) When the elevator car assembly of the present invention is used, the positioning cylinder can be reinforced by multiple reinforcing ribs to improve the rigidity of the positioning cylinder, thereby preventing it from bending and deforming after being subjected to force for a long time, thus affecting the installation stability of the assembly. At the same time, the lower baffle and the upper baffle can be reinforced by multiple reinforcing blocks to improve the deformation resistance of the lower baffle and the upper baffle, thereby effectively preventing the lower baffle and the upper baffle from bending and deforming when subjected to external impact, thus affecting their protective effect and service life.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1-4 As shown, this utility model discloses an assembly of protective railings for elevator cars, comprising several positioning cylinders 1. The positioning cylinders 1 are fixedly connected to the top of the elevator car, and a pair of slots 2 are provided on the top wall of the cylinder. A threaded tube 3 is fixedly connected to the outer wall of the top of the positioning cylinder 1, and the threaded tube 3 communicates with the inner cavity of the positioning cylinder 1. A screw 4 that mates with the threaded tube 3 is threadedly connected to the inner wall of the threaded tube 3. An upper baffle 5 and a lower baffle 6 are fixedly connected between the outer walls of two adjacent positioning cylinders 1, and a vertical rod 7 is inserted into each positioning cylinder 1. A protrusion 8 is fixedly connected to the top of the vertical rod 7, and several threaded grooves 9 are provided on the body of the vertical rod 7. A handrail 10 is fixedly connected between two adjacent vertical rods 7. When the protective railing assembly is installed on the top of the elevator car, it can surround the edge of the elevator car to play a protective and blocking role, thereby effectively preventing maintenance personnel from accidentally falling when working on the top of the car.

[0028] The positioning cylinder 1 is cylindrical and located at the four corners of the top surface of the elevator car. The inner diameter of the positioning cylinder 1 is equal to the diameter of the upright 7, and the diameter of the threaded groove 9 is equal to the inner diameter of the threaded tube 3. The threaded grooves 9 are equidistantly distributed along the axial direction of the upright 7. Each upright 7 can drive the handrail 10 to move up and down along the positioning cylinder 1. By tightening the screw 4 in the threaded tube 3, the screw 4 can be screwed into the corresponding threaded groove 9 until the end of the screw 4 is tightly pressed against the bottom of the threaded groove 9. At this time, the height of the guardrail assembly can be adjusted and fixed by the mutual cooperation between the screw 4 and the threaded groove 9 so that it can protect maintenance personnel of different heights and body types. When the guardrail assembly is damaged due to long-term use, each upright 7 can be pulled out from the positioning cylinder 1 by unscrewing the screw 4 so that the guardrail assembly can be disassembled and replaced.

[0029] Each positioning cylinder 1 has several reinforcing ribs 11 fixedly connected to its bottom outer wall. The reinforcing ribs 11 are triangular in shape and their bottoms are fixedly connected to the top surface of the elevator car. The reinforcing ribs 11 are distributed in an equidistant ring along the circumference of the positioning cylinder 1. The positioning cylinder 1 can be reinforced by multiple reinforcing ribs 11 to improve the rigidity of the positioning cylinder 1, thereby preventing it from bending and deforming after being subjected to force for a long time, which would affect the installation stability of the guardrail assembly.

[0030] The lower baffle 6 is located below the upper baffle 5, and the bottom surface of the lower baffle 6 is attached to the top surface of the elevator car. The lower baffle 6 can effectively fill the gap between the guardrail assembly and the top of the elevator car, so as to prevent maintenance tools or parts from falling from the top of the elevator car through the gap and causing safety hazards when maintenance personnel are working on the top of the car.

[0031] The lower baffle 6 and the upper baffle 5 are elongated strips, and several buffer blocks 12 are provided on the inner surface of both the lower baffle 6 and the upper baffle 5. The surface of the buffer block 12 is arc-shaped, and the buffer blocks 12 are equidistantly linearly distributed along the length direction of the lower baffle 6 and the upper baffle 5. The buffer blocks 12 can be made of elastic materials such as sponge and are fixed by means of glue. When maintenance personnel accidentally collide with the lower baffle 6 and the upper baffle 5 during maintenance, the impact force can be effectively decomposed and absorbed by each buffer block 12 to play a buffering protection role, thereby effectively preventing maintenance personnel from being injured by collision.

[0032] Among them, a number of reinforcing blocks 13 are fixedly connected between the lower baffle 6 and the upper baffle 5. The reinforcing blocks 13 are X-shaped and are distributed linearly at equal intervals along the length direction of the lower baffle 6 and the upper baffle 5. The lower baffle 6 and the upper baffle 5 can be reinforced by multiple reinforcing blocks 13 to improve the deformation resistance of the lower baffle 6 and the upper baffle 5, thereby effectively preventing the lower baffle 6 and the upper baffle 5 from bending and deforming when subjected to external impact, thus affecting their protective effect and service life.

[0033] The diameter of the handrail 10 is equal to the width of the slot 2. When the upright 7 is inserted into the positioning cylinder 1, each handrail 10 can fit into the corresponding slot 2 to achieve a limiting and fixing function. When maintenance personnel work on the top of the elevator car, they can maintain their balance through the handrail 10 to prevent falls. Each handrail 10 is fitted with an anti-slip sleeve 14. The inner diameter of the anti-slip sleeve 14 is equal to the diameter of the handrail 10, and the surface of the anti-slip sleeve 14 is provided with herringbone anti-slip texture. The anti-slip sleeve 14 can be made of elastic materials such as rubber and is fixed by means of glue. When holding the handrail 10, the anti-slip texture on the surface of the anti-slip sleeve 14 can increase the friction between the hand and the handrail 10 to achieve an anti-slip function, thereby preventing slippage and loss of hand when holding the handrail 10.

[0034] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0035] The working principle of this utility model is as follows:

[0036] In use, this utility model allows the guardrail assembly to be fixedly installed on the top of the elevator car. The guardrail assembly surrounds the edge of the elevator car, providing protection and preventing maintenance personnel from accidentally falling while working on the car top. Each upright 7 can move the handrail 10 up and down along the positioning cylinder 1. By tightening the screw 4 inside the threaded tube 3, the screw 4 can be screwed into the corresponding threaded groove 9 until the end of the screw 4 firmly abuts against the bottom of the threaded groove 9. The height of the guardrail assembly can be adjusted and fixed through the interaction between the screw 4 and the threaded groove 9, allowing it to protect maintenance personnel of different heights and builds. An upper baffle 5 and a lower baffle 6 are fixedly connected between the outer walls of two adjacent positioning cylinders 1. The lower baffle 6 effectively fills the gap between the guardrail assembly and the elevator car. The gap between the top sections is designed to prevent maintenance tools or parts from falling through the gap and causing safety hazards when maintenance personnel are working on the top of the elevator car. Multiple reinforcing ribs 11 can reinforce the positioning cylinder 1 to improve its rigidity and strength, thereby preventing it from bending and deforming after prolonged stress, which would affect the installation stability of the guardrail assembly. Multiple reinforcing blocks 13 can reinforce the lower baffle 6 and the upper baffle 5 to improve their deformation resistance, thereby effectively preventing them from bending and deforming under external impact, which would affect their protective effect and service life. When the guardrail assembly is damaged due to prolonged use, the individual uprights 7 can be pulled out of the positioning cylinder 1 by unscrewing the screws 4, so that the guardrail assembly can be disassembled and replaced.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
