Description

Technical Field

[0001] This utility model belongs to the field of elevator shaft construction operation platform, and relates to a mobile operation platform for elevator shafts. Background Technology

[0002] An elevator shaft is a vertical passage or space used for installing and operating elevators. It is typically constructed of concrete or steel, located at the center or edge of a building, running through all floors to allow the elevator to move up and down. The design and construction of elevator shafts must comply with a series of safety codes and building regulations to ensure the safety and stability of elevator operation. A mobile operating platform within the elevator shaft is a device used for maintenance, upkeep, or installation work. Existing elevator shaft operating platforms use tower cranes to suspend the platform at its four corners, allowing it to move up and down along the interior of the elevator shaft. This facilitates access for construction workers to different floors for installation work. However, in existing elevator shaft operating platforms, the slings used by the tower cranes are flexible, making it difficult to effectively control the platform's position in the center of the shaft. Consequently, the four edges of the platform easily rub against the walls during movement, causing wear and tear on both the platform and the shaft walls. This results in a lack of flexibility during platform movement, affecting its efficiency.

[0003] Therefore, this utility model provides a mobile operating platform for elevator shafts to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses an elevator shaft moving operation platform. The technical solution adopted is as follows: it includes a top cover, with symmetrical slots opened in the middle of the left and right side walls of the top cover. Hanging rings are fixedly installed at the four corners of the upper surface of the top cover. A wall buffer assembly is installed on the lower surface of the top cover. The wall buffer assembly includes a bidirectional screw rod rotatably installed in the middle of the lower surface of the top cover. The left and right sides of the bidirectional screw rod are respectively fitted with the center holes of the moving plates. Holes are opened on the front and rear sides of the left and right moving plates to movably fit moving columns. Tension springs are fitted at opposite ends of the left and right moving columns. Tension spring fixing seats are fixedly connected to the ends of the moving columns at opposite ends of the left and right moving columns. Universal wheels are fixedly installed at the outward ends of the left and right moving columns. Holes are also opened at the front and rear ends of the left and right moving plates to movably fit on guide columns. The left and right ends of the front guide columns are fixedly connected to the left and right inner side walls of the top cover. A first gear is fixedly fitted in the middle of the bidirectional screw rod. The rear side of the first gear meshes with the teeth of a second gear. The second gear is fixedly fitted on the output shaft of a motor. The motor is fixedly installed on the lower surface of the top cover.

[0005] In a preferred embodiment of this utility model, one end of the tension spring is fixedly connected to a corresponding tension spring fixing seat, and the other end of the tension spring is fixedly connected to a corresponding movable plate.

[0006] In a preferred embodiment of this utility model, the outward-facing ends of the left, right, front, and rear movable columns and the universal wheels respectively move through the front and rear ends of the left and right slots. This design facilitates the rotation of the bidirectional lead screw driven by the motor, thereby causing the left and right movable plates to move in opposite directions. This, in turn, causes the universal wheels at the ends of the movable columns to pass through or retract into the corresponding slots, making sliding contact with the wall of the elevator shaft. This avoids the left and right edges of the top cover rubbing against the wall when the operating platform moves up and down along the inner wall of the elevator shaft, preventing scratches and wear on the device and the wall. At the same time, it effectively reduces the friction between the operating platform and the inner wall of the elevator shaft, improving the efficiency of its up and down movement.

[0007] As a preferred embodiment of this utility model, vertical support frames are fixedly connected to the left and right sides of the inner side of the rear wall of the top cover, and triangular clips are fixedly connected to the left and right sides of the rear wall at the lower end of the vertical support frames. By using triangular clips, it is easy to clip the device onto the lower edge of the corresponding elevator entrance, thereby fixing the device to the corresponding floor.

[0008] As a preferred embodiment of this utility model, the left and right sides of the front sidewall at the lower end of the vertical support frame are respectively inclined upward and connected with reinforcing ribs, and the upper ends of the left and right reinforcing ribs are respectively fixedly connected to the left and right sides of the inner sidewall of the front sidewall of the top cover.

[0009] As a preferred embodiment of this utility model, a lithium battery and a controller are fixedly installed on the front and rear edges of the lower surface of the top cover, respectively; by using the controller, wireless transmission can be performed, thereby realizing wireless control of the motor rotation and avoiding the trouble of wiring.

[0010] The beneficial effects of this utility model are as follows: By driving the bidirectional lead screw to rotate via a motor, the left and right moving plates move in the same or opposite directions, thereby causing the casters at the ends of the movable column to pass through or retract into the corresponding slots. This improves the flexibility of the wall buffer assembly during use. When moving the operating platform inside the elevator shaft, the casters at the ends of the movable column pass through and retract into the corresponding slots. Under the action of the corresponding tension springs on the left and right sides, the casters make sliding elastic contact with the wall of the elevator shaft. This prevents the left and right edges of the top cover from rubbing against the wall when the operating platform moves up and down along the inner wall of the elevator shaft, thus avoiding scratches and wear on the device and the wall. At the same time, it effectively reduces the friction between the operating platform and the inner wall of the elevator shaft, improving its flexibility and efficiency in moving up and down.

Detailed Implementation

[0014] Example 1

[0015] like Figures 1 to 2As shown, the elevator shaft mobile operating platform of this utility model adopts the following technical solution: It includes a top cover 1, with symmetrical slots 11 opened in the middle of the left and right side walls of the top cover 1. Hanging rings 12 are fixedly installed at the four corners of the upper surface of the top cover 1. A wall buffer assembly 2 is installed on the lower surface of the top cover 1. The wall buffer assembly 2 includes a bidirectional screw 21 rotatably installed in the middle of the lower surface of the top cover 1. The left and right ends of the bidirectional screw 21 are installed on the lower surface of the top cover 1 through fixing ears. The left and right sides of the bidirectional screw 21 are respectively fitted into the center holes of the moving plates 22. Holes are opened on the front and rear sides of the left and right moving plates 22 to movably mount movable columns 23. Tension springs 24 are respectively mounted on opposite ends of the left and right movable columns 23. Tension spring fixing seats 231 are fixedly connected to the opposite ends of the movable columns of the left and right movable columns 23. One end of the tension spring 24 is fixedly connected to the corresponding tension spring fixing seat 231, and the other end of the tension spring 24 is fixedly connected to the corresponding moving plate 22. The outward-facing ends of the left and right movable columns 23 are respectively fixed... The casters 25 are installed, and the outward-facing ends of the movable columns 23 on the left, right, front, and rear sides, as well as the casters 25, respectively movably pass through the front and rear ends of the slots 11 on the left and right sides. The front and rear ends of the left and right movable plates 22 are also movably fitted onto the guide columns 26 with holes. The left and right ends of the guide columns 26 are respectively fixedly connected to the left and right inner side walls of the top cover 1. The first gear 3 is fixedly fitted in the middle of the bidirectional lead screw 21. The rear side of the first gear 3 meshes with the teeth of the second gear 4. The second gear 4 is fixedly fitted onto the output shaft of the motor 5. The motor 5 is fixedly installed on the lower surface of the top cover 1. Vertical support frames 6 are fixedly connected to the left and right sides of the inner side of the rear wall of the top cover 1. Triangular clips 61 are fixedly connected to the left and right sides of the rear wall of the lower end of the vertical support frame 6. Reinforcing ribs 7 are connected to the left and right sides of the front wall of the lower end of the vertical support frame 6 at an upward angle. The upper ends of the left and right reinforcing ribs 7 are fixedly connected to the left and right sides of the inner side of the front wall of the top cover 1. Lithium batteries 8 and controllers 9 are fixedly installed on the front and rear edges of the lower surface of the top cover 1, respectively.

[0016] The working principle of this utility model is as follows: When using this operating platform, a tower crane is used to connect the lifting rings at the four corners of the top cover 1 with slings, and then place it into the elevator shaft. The controller 9 can remotely control the motor 5 to rotate. The motor 5 drives the second gear 4 to rotate, and the second gear 4 drives the first gear 3 to rotate, which in turn drives the bidirectional lead screw 21 to rotate. The left and right moving plates 22 on the bidirectional lead screw 21 move to the left and right sides along the inner sidewall of the top cover 1, which in turn drives the left and right front and rear movable columns 23 and the corresponding universal wheels 25 to extend out of the slots 11 on the left and right sidewalls of the top cover 1. This causes the universal wheels 25 to make squeezing and sliding contact with the left and right inner sidewalls of the elevator shaft, thereby separating the left and right sides of the top cover 1 from the elevator shaft. When the tower crane moves the device up and down, the universal wheels 25 can slide and contact with the walls of the elevator shaft, thereby avoiding the left and right sides of the top cover 1 from rubbing against the elevator shaft and effectively reducing the resistance to its up and down movement. When the device is not in use, the motor 5 can be controlled to retract the left and right universal wheels 25 back into the top cover 1.
