[0019] Please refer to Figs. 1-3The application discloses a detection device for a construction elevator, which comprises a tilt detection device body arranged on a mounting plate 2, a horizontal detection assembly arranged on the upper portion of the mounting plate 2, and a mounting shaft 5 arranged on the lower portion of the mounting plate 2 through rotary connection. The outer surface of the mounting shaft 5 is fixedly provided with a bottom plate 6, and a tilt sensor 11 in communication with a controller is arranged below the bottom plate 6. The mounting shaft 5 is driven to rotate by a driving device in communication with the controller, so that the bottom plate 6 is always kept in dynamic balance with the horizontal plane. An angle ruler 13 is arranged on the side of the mounting plate 2 away from the driving device, and the center point of the angle ruler 13 is aligned with the axis of the mounting shaft 5. The horizontal detection assembly comprises a level tube 4, and a horizontal groove is specially designed on the mounting plate 2 for accurately mounting the level tube 4.

[0020] The driving device comprises a speed reducer 9, a driving gear 10, a driven gear 7 and a driving motor 8 in communication with the tilt sensor 11. The driving motor 8 is fixed on the mounting plate 2, the input shaft of the speed reducer 9 is connected with the output shaft of the driving motor 8, and the driving gear 10 is fixed on the output shaft of the speed reducer 9. The driven gear 7 is fixed on the mounting shaft 5 and is engaged with the driving gear 10. In order to facilitate the installation of the driving motor 8 and the speed reducer 9, corresponding notches are reserved on the mounting plate 2. In addition, an installation rod 12 is fixed on the side of the mounting plate 2 away from the driving device, and the angle ruler 13 is fixed on the installation rod 12 and located on the left side of the bottom plate 6. The mechanism of the tilt detection device body is described above, and the related structure and working principle of a crane body tilt detection device disclosed in application No. 202321868637.3 can be referred to. Although different instruments are applied, the detection purposes are the same, and the detection device can also be applied to the elevator. The subsequent principle will not be described.

[0021] The middle part of the mounting plate 2 is provided with a rectangular through hole 20, and a bidirectional screw rod 21 is transversely rotatably connected in the rectangular through hole 20. The outer side of the bidirectional screw rod 21 is symmetrically and threadedly connected with an L-shaped plate 27. The L-shaped plate 27 includes a horizontal plate and a vertical plate. The horizontal plate is fixedly connected to the upper end of the vertical plate and away from the center of the mounting plate 2. A first clamping space for clamping the vertical rod of an elevator T-shaped guardrail 29 is formed between the two L-shaped plates 27. The elevator T-shaped guardrail 29 is the uppermost end of the protective fence on the elevator. The elevator T-shaped guardrail 29 has a T-shaped cross section. Two U-shaped rods 24 are slidably connected to the two sides of the mounting plate 2. The middle part of each U-shaped rod 24 is fixedly connected with an extension plate. The position of the extension plate is adjusted according to the horizontal rod of the elevator T-shaped guardrail 29, so that the distance between the elevator T-shaped guardrail 29 and the mounting plate 2 can just clamp the horizontal rod of the elevator T-shaped guardrail 29. A second clamping space for clamping the horizontal rod of the elevator T-shaped guardrail 29 is formed between the U-shaped rod 24 and the upper end surface of the L-shaped plate 27. The extension plate is attached to the two sides of the horizontal rod of the elevator T-shaped guardrail 29, so that the mounting plate 2 and the elevator T-shaped guardrail 29 can be tightly attached and fixed. By installing a detection device on the elevator T-shaped guardrail 29, the rotation and movement of the mounting plate 2 can be prevented, and the accuracy of detection can be ensured.

[0022] Specifically, in order to facilitate the driving of the bidirectional screw rod 21, the two ends of the bidirectional screw rod 21 penetrate the end portions of the mounting plate 2 and are fixedly connected with a handle 23.

[0023] Specifically, the outer side of the bidirectional screw rod 21 is symmetrically and threadedly connected with a nut block 22, and the vertical plate of the L-shaped plate 27 is fixedly connected to the nut block 22.

[0024] Specifically, the lower end of the extension plate is fixedly connected with a mounting block 25 on both sides, and a plug rod 26 is inserted into the mounting block 25. The plug rod 26 penetrates the L-shaped plate 27, so that the U-shaped rod 24 and the horizontal plate of the L-shaped plate 27 are relatively fixed.

[0025] Specifically, the upper half of the mounting plate 2 is provided with a sliding groove 28, and the end portion of the U-shaped rod 24 is slidably connected in the sliding groove 28, so as to realize the installation of the U-shaped rod 24.

[0026] The installation method is as follows: firstly, rotate the bidirectional screw 21 counterclockwise to drive the nut block 22 to move towards the rotating handle 23, then insert the first clamping space into the vertical rod of the elevator T-shaped handrail 29 until the elevator T-shaped handrail 29 is attached to the mounting plate 2, after alignment, rotate the bidirectional screw 21 clockwise, so that the vertical plate of the L-shaped plate 27 is attached to the vertical rod of the elevator T-shaped handrail 29, and the tilt detection device body is moved upward, so that the vertical plate of the L-shaped plate 27 is attached to the horizontal rod of the elevator T-shaped handrail 29, then move the U-shaped rod 24 downward, so that the lower end of the U-shaped rod 24 is attached to the upper end of the horizontal rod of the elevator T-shaped handrail 29, at this time, the insertion rod 26 can be inserted into the mounting block 25 and the L-shaped plate 27, and the installation of the tilt detection device body is completed.
