Description

Technical Field

[0001] This utility model relates to a ladder, and more particularly to a telescopic safety ladder for elevator maintenance. Background Technology

[0002] In the field of elevator maintenance, ladders are indispensable auxiliary equipment. Traditional elevator maintenance ladders are mostly of fixed height, and their height cannot be flexibly adjusted according to the actual working scenario, such as the elevator shaft and the inspection position of the car. When facing elevator maintenance needs at different floor heights, or when different positions such as the top and bottom of the elevator need to be inspected, fixed-height ladders cannot meet diverse work requirements. Maintenance personnel may need to carry multiple sets of ladders of different specifications, resulting in low work efficiency and increased equipment transportation costs.

[0003] Furthermore, some height-adjustable ladders use complex bolt or snap-fit ​​connections, making adjustments cumbersome and time-consuming. These connections also pose a risk of loosening during climbing, affecting ladder stability and the safety of maintenance personnel. Additionally, non-retractable ladders are bulky, occupying significant space when not in use, making storage and transportation extremely inconvenient.

[0004] Based on the shortcomings of the existing technology, the development of a telescopic safety ladder for elevator maintenance that is simple in structure, easy to adjust, safe and reliable, and can adapt to different working heights has become an urgent problem to be solved in the industry. The telescopic design of this utility model is proposed to solve these technical pain points. Utility Model Content

[0005] In order to overcome the shortcomings mentioned in the background art, this utility model provides a telescopic elevator maintenance safety ladder.

[0006] The technical solution of this utility model is as follows: a telescopic elevator maintenance safety ladder, including a base support, telescopic tubes, connecting frame, pedals, top frame, inclined blocks and springs. Multi-stage telescopic tubes are symmetrically installed on the top of the base support. The outermost pipes of the two telescopic tubes are connected by the connecting frame. A pedal is installed between each pair of left-right symmetrical pipes at the same level. The topmost pipes are fixedly connected to the top frame. Except for the outermost pipe, the lower ends of the other pipes in the telescopic tubes are symmetrically slidably connected to inclined blocks. Two springs are connected between the inclined blocks and the inside of the pipes. When the telescopic tube is in the retracted state, the springs are in the compressed state.

[0007] As a further preferred option, it also includes a non-slip foot pedal, with a non-slip foot pedal attached to the outer side of the pedal.

[0008] As a further preferred option, it also includes anti-slip blocks, with anti-slip blocks connected to the rear side of the top frame.

[0009] As a further preferred option, it also includes pulleys and anti-slip rubber blocks. The pulleys are symmetrically installed on the base bracket, with the pulleys facing forward, and anti-slip rubber blocks are respectively fitted on the left and right ends of the base bracket.

[0010] As a further preferred option, it also includes a handle, with a handle connected to the front side of the top frame.

[0011] As a further preferred option, hooks are also included, with hooks detachably installed on the top of the uppermost pipe of the telescopic tube.

[0012] This utility model has the following advantages: 1. Through the multi-stage telescopic tube combined with the snap-fit ​​structure of the inclined block and the spring, in the face of elevator maintenance scenarios of different heights, the length of the telescopic tube can be flexibly and quickly adjusted by easily lifting the tube step by step, accurately adapting to the work requirements, avoiding the situation that the ladder cannot be used due to the fixed height of the ladder, effectively expanding the application range of the ladder, and providing greater flexibility and practicality for elevator maintenance work.

[0013] 2. When the ladder is not in use, the multi-stage telescopic tube can be retracted step by step, which can greatly reduce the overall volume of the ladder, making it easy to store in small spaces and saving storage space.

[0014] 2. The anti-slip foot pedal on the outside of the pedal increases friction and prevents people from slipping while climbing; the anti-slip block on the back of the top frame ensures that the ladder is firmly against the elevator wall; the anti-slip rubber block on the base support enhances the stability of the ground during use. The multi-structure work together to ensure the safety of maintenance personnel. Attached Figure Description

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] Example: A safety ladder for maintaining a telescopic elevator, such as... Figures 1-3 As shown, the system includes a base support 1, telescopic tubes 2, connecting frame 201, pedals 3, anti-slip foot pedals 4, top frame 5, inclined blocks 8, and springs 9. Multi-stage telescopic tubes 2 are symmetrically installed on the top of the base support 1. The outermost pipes of the two telescopic tubes 2 are securely connected via connecting frame 201. A pedal 3 is installed between each pair of symmetrical pipes at the same level. The topmost pipes are fixedly connected to the top frame 5. In actual use, the top frame 5 is aligned with the elevator wall, placing the ladder at an angle. Maintenance personnel can climb using the pedals 3. Anti-slip foot pedals 4 are connected to the outer side of the pedals 3, effectively increasing the friction between the maintenance personnel's feet and the pedals 3 to prevent slipping during climbing. Except for the outermost pipe, the telescopic tubes 2... The lower ends of the remaining pipes are symmetrically connected with inclined blocks 8. Two springs 9 are connected between the inclined blocks 8 and the inside of the pipe. When the telescopic pipe 2 is in the retracted state, the springs 9 are in the compressed state. When the pipe is pulled upward to extend it, the inclined blocks 8 are no longer obstructed and spring open to both sides under the elastic force of the springs 9. At this time, the inclined blocks 8 of the pipe are engaged with the top surface of the next adjacent pipe, so that the upper pipe is stably supported by the lower pipe, ensuring that the pipe remains in the extended state and realizing flexible adjustment of the ladder height. When it is necessary to retract the telescopic pipe 2, simply squeeze the inclined blocks 8 on both sides inward to retract them into the pipe. The springs 9 are compressed again, and then the pipe can be pushed downward to store it into the next level pipe. The retraction of the telescopic pipe 2 is completed by operating in sequence.

[0022] like Figure 1 and Figure 4 As shown, it also includes pulleys 11 and anti-slip rubber blocks 12. Pulleys 11 are symmetrically installed on the left and right sides of the base bracket 1, with the pulleys 11 facing forward. Anti-slip rubber blocks 12 are respectively fitted on the left and right ends of the base bracket 1. When moving the ladder, it is tilted forward so that the pulleys 11 contact the ground, so that it can be moved easily. When in use, the pulleys 11 are off the ground and the anti-slip rubber blocks 12 are in contact with the ground to ensure that the base bracket 1 is stable.

[0023] like Figure 1 and Figure 4As shown, it also includes anti-slip block 6, handle 13 and hook 14. The anti-slip block 6 is connected to the rear side of the top frame 5. When the ladder is tilted and supported against the elevator wall, the anti-slip block 6 is in close contact with the elevator wall, which enhances the positional stability of the ladder and ensures the safety of personnel climbing. The handle 13 is connected to the front side of the top frame 5, which makes it convenient for maintenance personnel to operate by pulling the handle 13 when unfolding or retracting the telescopic tube 2, improving the ease of use. The top of the uppermost pipe of the telescopic tube 2 can be detachably installed with hook 14. In specific scenarios, the hook 14 can be hooked and supported with the elevator bracket or wall to be climbed, so that the ladder can be used in a vertical state, which is suitable for climbing needs of different structures.
