[0002] Elevator maintenance is a comprehensive work involving multiple fields such as electrical and mechanical, aiming to ensure the normal operation of elevator equipment and the safety of passengers. In order to reduce the occurrence of elevator failures and improve the reliability and safety of elevators, preventive maintenance is very important. Preventive maintenance includes regular inspection, cleaning, lubrication, adjustment and replacement of wearing parts of elevators. Through preventive maintenance, problems can be discovered and solved in a timely manner, the occurrence and expansion of failures can be avoided, and the service life of the elevator can be extended. The components of vertical elevators are installed in various positions above and below the entire shaft, so problems may occur at each height and require maintenance. However, since the elevator car and counterweight frame run through the entire shaft, maintenance personnel can usually only carry out safe construction on the top of the car. If for some reason, construction cannot be carried out on the top of the car, but instead needs to be carried out away from the car or under the car, then the maintenance personnel are usually forced to choose dangerous high-altitude operations. Even with safety belts and safety ropes as insurance, they still face the risk of falling. Therefore, this application provides an elevator shaft maintenance auxiliary platform to meet the needs.

[0028] like Figures 1 to 4 As shown, an embodiment of the utility model provides an elevator shaft maintenance auxiliary platform, including a platform bracket 1, a guide fixing frame 3 and a fixed splint 4. The platform bracket 1 is detachably connected to the guide fixing frame 3, and the guide fixing frame 3 is detachably connected to the fixed guide rail 5 through the fixed splint 4; the platform bracket 1 is composed of multiple metal rods connected to each other, and a support rod 8 is installed at the bottom of the platform bracket 1, and a platform pedal 2 is horizontally arranged on the support rod 8. A platform guardrail 6 is provided on the side of the platform bracket 1, and the platform guardrail 6 is arranged vertically to the platform bracket 1. The platform guardrail 6 is used to protect construction workers from falling.

[0029] like Figure 3 As shown, the guide fixing frame 3 includes guide fixing members 11 and fixing rods 14. The number of fixing rods 14 is at least four and they are arranged in parallel. The guide fixing members 11 are divided into two groups, and the two groups of guide fixing members 11 are fixedly connected to the two ends of the fixing rods 14. The platform bracket 1 is connected to the fixing rods 14 by bolts. The surface of the fixing rods 14 near the platform bracket 1 is provided with multiple mounting holes 15 that are compatible with the bolts.

[0030] like Figure 2 As shown, the platform bracket 1 is fixedly connected to a diagonal reinforcement rod 9. A connecting block 10 is provided at the end of the diagonal reinforcement rod 9 away from the platform bracket 1. The connecting block 10 is fixedly connected to a fixing rod 14. There are two sets of diagonal reinforcement rods 9, and the two sets of diagonal reinforcement rods 9 are symmetrically arranged. The diagonal reinforcement rods 9 prevent the platform tread 2 from tilting horizontally due to weight imbalance when construction workers stand on it.

[0031] like Figure 3As shown, the fixing plate 4 is provided with a plurality of first assembly holes 12, and the guide fixing member 11 is provided with a plurality of second assembly holes 17, which correspond one to one with the first assembly holes 12. Fixing bolts 13 are installed between the first assembly holes 12 and the second assembly holes 17.

[0032] like Figure 4 As shown, the guide fixing member 11 is adapted to the shape of the fixed guide rail 5, and a groove 16 is provided on the side of the guide fixing member 11 facing the fixed guide rail 5. The groove 16 can be tightly attached to and stuck on the fixed guide rail 5 to prevent the guide fixing frame 3 from tilting when the weight of the front and rear of the platform is unbalanced.

[0033] The working principle of the technical solution provided by the utility model is as follows:

[0034] During use, the specific height position where construction is required and the position where the platform needs to be fixed are determined according to the elevator failure situation. If the car needs to be at the bottom of the platform during construction, the platform is carried on the top of the car. The guide fixing frame 3 and the fixing splint 4 are first installed at the predetermined position, and then the platform bracket 1, platform guardrail 6, and platform pedal 2 are assembled in sequence. Then the construction workers wear safety belts and safety ropes to enter the construction.

[0035] If the car needs to stop on the upper part of the platform during construction, the platform will be installed at the floor door near the lower part of the car. Construction workers are required to wear safety belts and safety ropes in advance. At the same time, safety ropes need to be connected during the installation of each part as secondary protection to prevent falling. If the construction position on the platform pedal 2 is too low, 1 to 2 platform pedals 2 can be added and fixed.

[0036] In the above scheme, the elevator shaft maintenance auxiliary platform has high safety, simple structure, low equipment cost, can efficiently carry out construction of various parts in the elevator shaft, and the overall combined process is easy to operate and can be widely promoted.

[0037] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the preferred embodiments of this invention, but those skilled in the art can fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion about the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
