Description

Technical Field

[0001] The utility model belongs to the technical field of elevator door deformation measurement, and particularly relates to an elevator door deformation measuring instrument. Background Art

[0002] The main reasons for elevator door deformation include the following: Mechanical failure: Deformation of the elevator door guide rail or wear of the slider may cause obstruction of the door leaf movement, thereby causing deformation. This is usually caused by long-term use and lack of maintenance. External force: For example, the decoration workers blocked the elevator door with glass, causing the glass to be clamped when the elevator started, thereby causing the elevator door to deform and the elevator to be damaged. Environmental factors: In low temperature weather, cold air enters the elevator hall door through the elevator shaft, creating a pressure difference, resulting in increased resistance to closing the door. Long-term pressure may cause the door leaf to deform.

[0003] When the deformation of the elevator door is slight, it is impossible to observe with the naked eye whether the elevator door is deformed. As a result, the elevator door is usually measured by the staff taking the detection device and moving it on the surface of the elevator door to measure the elevator door surface. However, it is inconvenient to measure the higher part of the elevator door. At the same time, the detection device may not be perpendicular to the ground during the movement, which makes it difficult to detect the tilt of the elevator door in time. Utility Model Content

[0026] By placing the box body 1 on one side of the elevator door, the first motor 3 drives the first driving gear 4 to rotate, so that the second driving gear 5 and the threaded rod 6 rotate, so as to drive the threaded barrel 7 to move upward, which can push the top plate 8 to move upward. The upper end of the top plate 8 contacts the upper end of one side of the elevator door, which can keep the shell 12 and the ground horizontally arranged, so that the multiple contact detection blocks 18 are arranged vertically to the ground. The stabilizing blocks on both sides of the threaded barrel 7 are respectively located in the two stabilizing grooves and slide, thereby improving the stability of the movement of the threaded barrel 7. A detachable mobile power supply is connected to one side of the outer wall of the box body 1;

[0027] The upper end of the moving component is connected to a top plate 8, the lower end of the top plate 8 is connected to a hydraulic cylinder 9, the lower end of the hydraulic cylinder 9 is connected to a moving plate 10, the middle of one side of the moving plate 10 is connected to an electric telescopic rod 11, one end of the electric telescopic rod 11 extends through to one side of the moving plate 10, one end of the electric telescopic rod 11 is connected to a detection component, the detection component is convenient for detecting one side of the elevator door, the detection component includes a shell 12, the middle of one side of the shell 12 is connected to a second motor 13, the output end of the second motor 13 extends through to the inside of the shell 12, and the output end of the second motor 13 is connected to the first bevel gear 1 4. One side of the first bevel gear 14 is meshedly connected to the second bevel gear 15. The inner wall of the second bevel gear 15 is connected to a screw rod 16. Both ends of the screw rod 16 are slidably connected to a moving block 17. The middle part of one side of the housing 12 and the middle part of one side of the two moving blocks 17 are connected to a contact detection block 18. One end of the two moving blocks 17 is connected to a support plate 19. One side of the two support plates 19 is evenly embedded with moving balls 20. The middle of the inner wall of the housing 12 is connected to a connecting ring. Slide rods are connected to the corresponding connecting rings on both sides of the screw rod 16. One end of the two slide rods is respectively located on the inner wall of the connecting ring for sliding connection;

[0028] An audible and visual alarm is installed inside the contact detection block 18. The contact detection block 18 is connected to the audible and visual alarm through a wire and contacts the upper end of the elevator hall outside the elevator door through the top plate 8, so that multiple contact detection blocks 18 are arranged vertically with the ground. The electric telescopic rod 11 pushes the shell 12 to move to one side, so that multiple contact detection blocks 18 are respectively in contact with one side of the elevator door, and the first bevel gear 14 is driven to rotate by the second motor 13, so that the second bevel gear 15 is engaged with the first bevel gear 14, which can drive the second bevel gear 15 and the screw rod 16 to rotate.

Multiple moving balls 20 contact the walls on both sides outside the elevator hall respectively. The hydraulic cylinder 9 pushes the moving plate 10, the shell 12 and the multiple contact detection blocks 18 to move on one side of the elevator door, which can detect one side of the elevator door. When the elevator door is tilted or deformed, the contact detection block 18 cannot contact one side of the elevator door, causing the contact detection block 18 to issue an alarm, so that the detection staff can quickly find where the elevator door is deformed.

[0029] Working principle: When using the device, place the device on the side of the elevator door that needs to be detected, and use the first motor 3 to drive the first drive gear 4 and the second drive gear 5 to rotate, so that the threaded rod 6 rotates, drives the threaded cylinder 7 to move upward, and pushes the top plate 8 to contact the upper end outside the elevator hall. The electric telescopic rod 11 pushes the shell 12 to one side, and multiple contact detection blocks 18 contact one side of the elevator door. The second motor 13 drives the first bevel gear 14 to rotate, drives the second bevel gear 15 and the screw rod 16 to rotate, so as to drive the two moving blocks 17 and the two support plates 19 to move. The two support plates 19 contact the walls on both sides outside the elevator hall, which can detect elevator doors of different widths. At the same time, multiple moving balls 20 contact the elevator door to be detected, and the hydraulic cylinder 9 pushes the shell 12 and the multiple contact detection blocks 18 to move on one side of the elevator door. When the elevator door is tilted or deformed, the contact detection block 18 cannot contact the deformed part of the elevator door, causing the contact detection block 18 to issue an alarm, which facilitates rapid detection of the elevator door.
