Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to an emergency platform for elevator maintenance. Background Art

[0002] With the increasing number of high-rise buildings, elevators have become an indispensable means of vertical transportation in people's daily lives. The safe operation of elevators is of vital importance, and regular maintenance is an important means to ensure the safety and reliability of elevators.

[0003] However, current elevator maintenance often faces several challenges. For one thing, traditional elevator maintenance methods lack a dedicated emergency response platform. When maintenance personnel encounter unexpected situations during elevator maintenance, such as accidental damage to elevator components or control system failures, the lack of a suitable emergency response platform makes it difficult for them to quickly and effectively respond. This can extend maintenance time, impact the normal operation of the elevator, and even pose a potential threat to passenger safety.

[0004] A search revealed that a Chinese patent document disclosed an emergency platform for elevator repair and maintenance [Application No.: 201920929053.X, Publication No.: CN210366895U], which includes an emergency platform body, with columns fixedly connected to both sides of the top of the emergency platform body, and guardrails provided on the inner sides of the columns. Although this emergency platform can achieve the desired effect, it has poor adaptability and an unreliable structure. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1 to 7 The utility model provides a technical solution: an emergency platform for elevator maintenance, characterized by:

[0040] Including base, support frame and operating platform;

[0041] An operating platform is provided on the top of the support frame, and a base is provided on the bottom of the support frame;

[0042] The base includes a base platform 101, a drive device 102, wheels 103 and a ladder 104. The drive device 102 is arranged at the bottom of the base platform 101, the output end of the drive device 102 is installed with wheels 103, and the ladder 104 is arranged on the side of the base platform 101;

[0043] The support frame includes an outer support arm 201, an inner support arm 202 and a hydraulic cylinder 203. The outer support arm 201 and the inner support arm 202 are connected by a connecting rod 204. One end of the hydraulic cylinder 203 is set on the inner support arm 202, and the other end of the hydraulic cylinder 203 is set on the inner support arm 202.

[0044] The operating platform includes an operating table 301, a guardrail 302, a protective door 303, a movable platform 304 and a protective baffle 305. A protective door 303 is provided at one end of the operating table 301, and the protective door 303 and the ladder 104 are located on the same side. A movable platform 304 is movably provided at the other end of the operating table 301, and a protective baffle 305 is installed on the movable platform 304. Guardrails 302 are provided on both sides of the operating table 301.

[0045] The base platform 101 is internally provided with batteries and electronic control equipment.

[0046] Specifically, trap doors 105 are provided on both sides of the base platform 101, handle holes 401 are provided on the trap doors 105, and emergency stop switches 402 are provided on the trap doors 105. The trap doors 105 can be used to quickly and easily maintain the internal equipment. The design of the handle holes 401 makes it easy to observe the internal conditions of the equipment and can also ventilate and dissipate heat. The emergency stop switches 402 on both sides can ensure that braking can be performed immediately when problems occur, avoiding the situation where emergency braking is not timely due to the emergency stop switch 402 being provided on only one side.

[0047] Specifically, a counterweight block 106 is provided at the bottom of the base, which can effectively reduce the shaking of the equipment during operation and enhance the stability of the platform. The setting of the counterweight block 106 can provide better balance when the equipment is lifted or moved, and prevent the risk of overturning due to the shift of the center of gravity.

[0048] Specifically, the protective baffle 305 can be movably installed on the operating table 301, and the protective baffle 305 can be installed or removed as needed. This movable installation design improves the adaptability of the equipment. When a larger device needs to be transported to the platform, the protective baffle 305 can be removed for easy transportation, which greatly enhances the functionality and ease of use of the operating table 301.

[0049] Specifically, the support frame adopts a scissor-like arrangement, which allows it to achieve a greater range of extension and retraction within a limited space, improving the platform's lifting efficiency and stability. The scissor-like structural design effectively distributes the load, reduces stress concentration at a single support point, and enhances the support frame's load-bearing capacity and resistance to deformation. This design also ensures that the support frame remains stable during the lifting process, preventing the platform from tilting or shaking, further improving operational safety and the platform's service life.

[0050] Specifically, a solenoid valve is installed within drive device 102, enabling real-time control of drive device 102 and improving operational efficiency and safety. This solenoid valve configuration helps prevent malfunction of drive device 102 due to unexpected power outages or voltage fluctuations, ensuring stable operation under various operating conditions. This design not only enhances the system's automation level but also reduces the complexity of maintenance and troubleshooting, thereby increasing overall device reliability and lifespan.

[0051] Specifically, a safety support frame 205 is provided on the connecting rod 204, which can provide additional support and stability when the connecting rod 204 is subjected to force, and effectively prevent the connecting rod 204 from deforming or breaking during operation. This design enhances the bearing capacity and safety of the overall structure and reduces the risk of accidents that may be caused by failure of the connecting rod 204.

[0052] Specifically, guardrails 306 are provided on both sides of the movable platform 304. These guardrails 306 provide effective safety protection for operators, preventing them from accidentally falling during the platform's lifting, lowering, or movement. The design of guardrails 306 also standardizes standing and operating positions, preventing potential safety hazards caused by accidental collisions or errors, and improving overall operational safety and efficiency.
