Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance equipment technology, and more specifically, to an operating platform for elevator maintenance. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building, with its car moving between at least two rigid guide rails perpendicular to the horizontal plane or at an angle of inclination less than 15 degrees to the vertical. There are also escalators, where steps are mounted on a continuous track and run continuously; these are commonly known as moving walkways or automatic stairs. They are fixed lifting devices serving designated floors. A vertical elevator has a car that runs between at least two rigid guide rails that are vertical or at an angle of inclination less than 15 degrees. The size and structure of the car facilitate passenger entry and exit or loading and unloading of goods. Conventionally, regardless of its drive method, elevator is considered a general term for vertical transportation tools within a building. Elevators require regular maintenance and are prone to malfunctions requiring repair.

[0003] During elevator maintenance, maintenance personnel often need to enter the elevator car and access the top of the car through a connection point inside the car to perform maintenance work. Currently, maintenance personnel typically use a folding ladder to enter the top of the car. This method of entry is prone to the following problems: The elevator car may shift during operations on the top of the car, affecting the maintenance personnel on top and causing instability and potential danger. Furthermore, using a folding ladder inside the car is inconvenient due to the narrow interior space, making it difficult to unfold stably. This invention proposes a new solution to these problems. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a solution to the technical problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An operating platform for elevator maintenance includes a standing platform. Multiple sets of support columns are symmetrically arranged on both sides of the standing platform. Connecting through holes are provided on the end faces of both sides of the standing platform corresponding to the positions of the support columns. Connecting arms are provided on the support columns corresponding to the positions of the connecting through holes. The support columns are connected to the standing platform by inserting the connecting arms into the connecting through holes. Two sets of support arms are symmetrically arranged between two sets of support columns. A first push rod is fixedly installed on the outer end face of the support arm. A door stop is fixedly installed on the output end of the first push rod. Multiple sets of second push rods are fixedly installed inside the top of the support columns. Supporting crossbars are fixedly installed on the output ends of the two symmetrical sets of second push rods. A reinforcing column is fixedly installed on the top of the upper end face of the supporting crossbar. A ladder is provided on the top of the lower end face of the standing platform.

[0007] Preferably, two sets of buffer sleeves are symmetrically arranged on the inner end face of the reinforcing column along the transverse centerline. A buffer spring is fixedly installed inside the buffer sleeve, and a slider is slidably connected inside the buffer sleeve. The end of the slider is fixedly connected to the top of the buffer spring, and a support block is fixedly installed at the top of the slider.

[0008] In any of the above embodiments, it is preferred that the ladder and the bottom of the corresponding two sets of supporting columns are fixedly installed with a movable plate, and multiple sets of movable wheels are evenly distributed and fixedly installed on the lower end surface of the movable plate.

[0009] In any of the above embodiments, it is preferred that a protective plate is rotatably installed on one end face between the supporting columns, and support strips are provided symmetrically on the top of the protective plate supporting the end face of the supporting columns.

[0010] In any of the above embodiments, it is preferred that a battery is fixedly installed on one end face of the protection plate, and an operation panel is installed above the battery on one end face of the protection plate.

[0011] In any of the above embodiments, it is preferred that a friction block is fixedly installed at the top of the support block.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This utility model provides an operating platform for elevator maintenance. By setting the standing platform among multiple sets of support columns and installing support crossbars and reinforcing columns at the top of the support columns, elevator maintenance personnel can fix the device inside the elevator by driving the first push rod after entering the top of the car. The second push rod drives the support crossbars to fix the longitudinal position of the elevator. The support block at the top of the support crossbars prevents the elevator car from shifting, ensuring the safety of the maintenance personnel at the top. At the same time, the stable connection of the support columns, standing platform and ladder makes the climbing process safer and more stable for maintenance personnel. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figures 1 to 4 An operating platform for elevator maintenance includes a standing platform 1. Multiple sets of supporting columns 2 are symmetrically arranged on both sides of the standing platform 1. Connecting through holes 3 are opened on the end faces of both sides of the standing platform 1 corresponding to the positions of the supporting columns 2. Connecting arms 4 are provided on the supporting columns 2 corresponding to the positions of the connecting through holes 3. The supporting columns 2 are connected to the standing platform 1 by inserting the connecting arms 4 into the connecting through holes 3. Two sets of supporting arms 5 are symmetrically arranged between the two sets of supporting columns 2. A first push rod 6 is fixedly installed on the outer end face of the supporting arm 5. A door baffle 7 is fixedly installed on the output end of the first push rod 6. Multiple sets of second push rods 8 are fixedly installed inside the top of the supporting columns 2. Supporting crossbars 9 are fixedly installed on the output ends of the two symmetrical sets of second push rods 8. A reinforcing column 10 is fixedly installed on the top of the upper end face of the supporting crossbar 9. A ladder 11 is provided on the top of the lower end face of the standing platform 1.

[0022] In this embodiment, two sets of buffer sleeves 12 are symmetrically arranged on the inner end face of the reinforcing column 10 along the transverse centerline. A buffer spring 13 is fixedly installed inside the buffer sleeve 12. A slider 14 is slidably connected inside the buffer sleeve 12. The end of the slider 14 is fixedly connected to the top of the buffer spring 13. A support block 15 is fixedly installed at the top of the slider 14.

[0023] In this embodiment, the ladder 11 and the bottom of the corresponding two sets of supporting columns 2 are fixedly installed with movable plates 16, and multiple sets of movable wheels 17 are evenly distributed and fixedly installed on the lower end surface of the movable plates 16.

[0024] In this embodiment, a protective plate 18 is rotatably installed on one end face between the supporting columns 2, and a support strip 19 is provided on the top of the protective plate 18 to symmetrically support the end face of the supporting column 2.

[0025] In this embodiment, a storage battery 20 is fixedly disposed on one side of the protection plate 18, and an operation plate 21 is disposed above the storage battery 20 on one side of the protection plate 18.

[0026] In this embodiment, a friction block 22 is fixedly installed on the top of the support block 15.

[0027] The working process of this utility model is as follows:

[0028] In use, this utility model first moves the device to the elevator car door where the operation is required using the moving wheels 17. Then, multiple sets of support columns 2 located on both sides of the standing platform 1 are extended by connecting arms. The first push rod 6 drives the door baffle 7 to fix the doors on both sides of the car using the operating plate 21. The second push rod 8 drives multiple sets of support crossbars 9 to lift them to the top of the car door using the operating plate 21. At the same time, it ensures that the support block 15 above the reinforcing column 10 is tightly attached to the top wall of the outer side of the car. After the operator enters the car, the protective plate 18 rotatably connected to the support column 2 can be lowered to prevent other personnel from entering the car. The operator can then access the top of the car via the ladder 11 and the standing platform 1.

[0029] Compared to the current method of accessing the top of the elevator car via a folding ladder, this device, by placing the standing platform 1 between multiple sets of supporting columns 2 and installing a supporting crossbeam 9 and a reinforcing column 10 at the top of the supporting columns 2, allows elevator maintenance personnel to fix the device inside the elevator by driving the first push rod 6 after entering the top of the car. The second push rod 8 drives the supporting crossbeam 9 to fix the longitudinal position of the elevator. The support block 15 at the top of the supporting crossbeam 9 prevents the elevator car from shifting, ensuring the safety of the maintenance personnel at the top. At the same time, the stable connection of the supporting columns 2, the standing platform 1, and the ladder 11 makes the climbing process safer and more stable for maintenance personnel.
