[0003] The car is generally suspended, and then the limiter and the driving part are set to achieve the vertical movement of the car up and down. There are various components on the top of the car to drive and protect the car. Elevator failure or regular maintenance requires workers to stand on the top of the car to work. The guardrail on the top of the car is used to protect the workers and also facilitate the workers to move around on the car.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the guardrail is arranged around the top of the car, and one end is arranged as an open structure to facilitate the up and down movement of personnel. The existence of the fence forms an obstacle between the top of the car and the columns on both sides of the elevator shaft. However, the connection is a part where faults are prone to occur and is also a key part of maintenance. Due to the existence of the guardrail, the maintenance work will be affected and the convenience of operation will also be affected. Secondly, since there are various components such as driving parts, power connecting parts, locking protection parts, etc. on the top of the car, the troubleshooting process generally requires the help of detection equipment. The space on the car is limited, which makes it impossible for the detection equipment to be stably placed and detected, which is not conducive to the maintenance work.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1 - Figure 4 This application is described in further detail.

[0023] Reference Figure 1 - Figure 2 , an elevator car guardrail structure, the guardrail consists of a first guardrail 1 and a second guardrail 2, a quick-disassembly opening and closing mechanism 3 is provided between the first guardrail 1 and the second guardrail 2, the opening and closing mechanism 3 is located at the connection between the middle of the top of the car and the columns on both sides of the elevator shaft, and a supporting mechanism 4 for the placement of detection equipment and parts during maintenance is provided on the inner side of the first guardrail 1; the opening and closing mechanism 3 includes a first clamping rod 301 located on the side of the first guardrail 1 close to the second guardrail 2 and a second clamping rod 302 located on the side of the second guardrail 2 close to the first guardrail 1, and a telescopic rod 303 fixed on the first clamping rod 301 and the second clamping rod 302, and telescopic holes 304 for the telescopic rod 303 to slide are provided on the first guardrail 1 and the second guardrail 2.

[0024] Reference Figure 2 - Figure 3 The opening and closing mechanism 3 also includes an insertion block 305 connecting the first clamping rod 301 and the second clamping rod 302 and a slot 306 for clamping the two. A slot 307 for inserting the insertion block 305 is provided inside the second clamping rod 302. A clamping block 308 is provided in the slot 307 through a torsion spring and is engaged with the slot 306. The insertion and engagement are carried out simultaneously, which has the advantages of convenient operation and high connection reliability. The clamping block 308 is engaged with the slot 306 through a torsion spring.

[0025] Reference Figure 2 - Figure 3A linkage rod 309 fixed to the plug block 305 is vertically slidable inside the first clamp rod 301, and a return spring 310 is provided between the linkage rod 309 and the first clamp rod 301. A lever 311 passing through the first clamp rod 301 is fixed to the upper end of the linkage rod 309 close to the outer side of the first guardrail 1. The lever 311 is set at the upper end of the outer side, and the operation convenience of the upper end will be better. The outer side can prevent accidental touch, so as to prevent the staff from triggering the opening and closing mechanism 3 when repairing other parts, and the reliability is better. The first clamp rod 301 is provided with movable slots for the two plug blocks 305 to move upward.

[0026] Reference Figure 2 - Figure 3 A guide rod 312 is fixed on the first clamp rod 301 and the second clamp rod 302, and the guide rod 312 slides through the first guardrail 1 and the second guardrail 2. An opening spring 313 is provided between the end of the guide rod 312 and the first guardrail 1 and the second guardrail 2 to open the first clamp rod 301 and the second clamp rod 302 to both sides. A buffer pad 314 is provided on the side of the first clamp rod 301 close to the first guardrail 1 and the side of the second clamp rod 302 close to the second guardrail 2. The opening spring 313 is used for automatic opening of the first clamp rod 301 and the second clamp rod 302 after they are disengaged, and they are always in an open state when not affected by external force for easy maintenance. The buffer pad 314 can play a buffering and silencing role.

[0027] Reference Figure 4 The support mechanism 4 includes a support plate 401 hinged on the inner side of the first guardrail 1 and used for placing the detection equipment, and a placement groove 402 integrally arranged on the support plate 401 for placing maintenance parts. After the support plate 401 is opened, it is parallel to the car, and the placement groove 402 is concave. Support platforms 403 for positioning and supporting the support plate 401 are fixed at both ends of the inner side of the first guardrail 1. The support mechanism 4 reasonably utilizes the space above the car and is provided with retractable support parts, which is convenient for the stable placement and use of the detection equipment and improves the convenience of maintenance work. The position of the support platform 403 will not have a significant impact on the maintenance work.

[0028] Reference Figure 4 A magnetic strip 405 is provided at the middle of the first guardrail 1 and the support plate 401 away from the hinged end of the first guardrail 1. The two magnetic strips 405 attract each other. A paddle 404 is provided on the side of the support plate 401 close to the magnetic strip 405. The support plate 401 is stored on the inner wall of the first guardrail 1 through the mutual fit of the two magnetic strips 405.

[0029] Working principle: When the car is normal, the support mechanism 4 is in the storage state, and the opening and closing mechanisms 3 on both sides are also in the closed state. When there is no need to inspect the connection between the car and the column, the opening and closing mechanisms 3 are also in the closed state;

[0030] When it is necessary to open the opening and closing mechanism 3 to inspect the connection between the car and the column, the lever 311 is held from the outside of the first guardrail 1 and pulled upward, the linkage rod 309 and the plug block 305 move upward accordingly, and the reset spring 310 is gradually compressed. When the clamping groove 306 and the clamping block 308 are completely offset, the first clamping rod 301 and the second clamping rod 302 are separated from each other, and the opening spring 313 resets the two to move in opposite directions. At this time, the guardrail of the connection between the car and the column is in the open state, and the staff can inspect and maintain this part.

[0031] After the inspection of this part is completed, the opening and closing mechanism 3 needs to be closed, and the first clamping rod 301 and the second clamping rod 302 are pulled inward at the same time, the telescopic rod 303 slides inside the telescopic hole 304, and the guide rod 312 moves accordingly, the opening spring 313 is gradually compressed, the plug block 305 is inserted into the slot 307, and the two symmetrical clamping blocks 308 are squeezed outward. After being fully inserted, the clamping block 308 is engaged with the clamping slot 306 under the action of the reset torsion spring, and the closing of the single-sided opening and closing mechanism 3 is completed;

[0032] When it is necessary to pass through the equipment during maintenance, the support plate 401 is opened downward and supported on the support platform 403, and the magnetic strip 405 is detached from the adsorption. The support plate 401 is convenient for the placement and operation of the detection equipment. The placement groove 402 is recessed for the placement of small parts for disassembly and assembly to prevent small parts from falling. After use, the support plate 401 is flipped upward, and the two magnetic strips 405 are attracted to complete the storage.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
