Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically a precision positioning hoisting device for installing hydraulic gates. Background Technology

[0002] Hydraulic gates are important water conservancy facilities used to control water flow and regulate water levels. In the construction of water conservancy projects, the installation accuracy of gates directly affects their performance and safety. Due to their large size and heavy weight, gates need to be moved and positioned with the help of hoisting equipment during installation.

[0003] The reference patent title is: A gate installation device for water conservancy construction (Authorization Announcement No.: CN219808341U, Authorization Announcement Date: 2023.10.10), which includes a bridging plate. The upper end surface of the bridging plate is provided with a hoisting guide mechanism. The hoisting guide mechanism includes an anti-sway positioning seat and an alignment hole. The anti-sway positioning seat is fixed in the middle of the upper surface of the bridging plate, and the alignment hole is opened through the upper surface of the bridging plate. The gate body is provided inside the bridging plate. The lower part of the bridging plate has a clamping mechanism, which includes symmetrically arranged anti-shifting plates. The anti-shifting plates are slidably connected to the lower part of the bridging plate. This device, through the hoisting guide mechanism, allows the hoisting equipment to descend and control the gate body to extend downward along the anti-sway positioning seat during the installation of the gate body. This ensures stable hoisting and lowering of the gate, thereby reducing the difficulty of gate installation.

[0004] Based on the above-mentioned documents, in the existing technology, hydraulic gate hoisting devices mostly use conventional cranes with hooks for hoisting, which has the following shortcomings: First, there is a lack of auxiliary positioning structure, and the gate is prone to shaking during hoisting, posing a safety hazard; second, the flexibility and precision of adjusting the rotation angle of the gate after hoisting are insufficient, making it difficult to accurately align the gate with the installation position, requiring multiple adjustments, resulting in low efficiency. Therefore, this utility model provides a precise positioning hoisting device for hydraulic gate installation. Utility Model Content

It solves the problems of existing hoisting devices lacking auxiliary positioning structures, which leads to gates easily shaking after hoisting, posing safety hazards, and insufficient precision in adjusting the gate's rotation angle after hoisting, thus affecting installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision positioning and hoisting device for installing hydraulic gates, comprising a bridge-building body, wherein a movable seat is slidably driven on the bridge-building body via a movable device, and a hoisting mechanism is provided at the bottom of the movable seat, the hoisting mechanism comprising:

[0026] The hoisting assembly 31 includes an equipment box 311 installed at the bottom of the movable seat 2.

[0028] It should be noted that the main body 1 of the bridge frame is fixedly installed on the vehicle body, and the bridge frame 1 is moved by the vehicle body. The main body 1 of the bridge frame includes a base shaft for fixing. The lifting shaft is driven by a hydraulic cylinder to slide up and down inside the base shaft.

One end of the moving screw is rotatably connected to the other side of the inner wall of the support arm, and the surface of the moving screw is threadedly connected to the inside of the moving seat 2. At the same time, the inner wall of the support arm is equipped with a limiting strip for guiding and limiting the sliding of the moving seat 2, so that the moving seat 2 keeps sliding horizontally. This part is a commonly used structure in the present invention, so it is not described in detail in the claims.

[0029] The limiting rod 315 is used to limit the sliding of the sliding plate 316.

[0030] Rubber pads are installed on opposite sides of the two auxiliary positioning plates 318 to prevent the auxiliary positioning plates 318 from directly contacting the gate and causing collision damage.

[0031] The electric hoist 313 adopts the CD1 type wire rope electric hoist, equipped with a rope breakage protection device and limit switch, and the two sets of electric hoists 313 are controlled by the control system to achieve synchronous start and stop.

[0032] The hook is made of 314 stainless steel with a tongue-type anti-detachment device and is galvanized for rust prevention.

[0033] By setting up the hoisting mechanism 3, the electric hoist 313 drives the hook 314 to lift and lower to realize the hoisting of the gate. The drive component 32 drives the auxiliary positioning plate 318 to slide. The position of the auxiliary positioning plate 318 can be adjusted according to the width of the gate to limit the gate on both sides, prevent the gate from shaking during hoisting, and improve the positioning accuracy and safety.

[0034] In this embodiment, a symmetrical sliding groove 5 is provided at the bottom of the support plate 312, and the inner surface of the sliding groove 5 is slidably connected to the surface of the sliding rod 317.

[0035] In this embodiment, the drive assembly 32 includes a drive motor 321 mounted on one side of the support plate 312. One end of the output shaft of the drive motor 321 is fixedly connected to a bidirectional lead screw 322 via a coupling.

The surface of the bidirectional lead screw 322 is threadedly connected to the inside of the sliding plate 316.

[0036] Drive motor 321 is a three-phase asynchronous motor;

[0037] In this embodiment, the rotating assembly 4 includes a rotating motor 41 installed on one side of the equipment box 311. One end of the output shaft of the rotating motor 41 is fixedly connected to a worm gear 42 via a coupling. The surface of the worm gear 42 drives the connecting shaft 44 to rotate inside the equipment box 311 via the linkage assembly 43. The bottom end of the connecting shaft 44 is fixedly connected to the top of the support plate 312.

[0038] Rotary motor 41 is a three-phase asynchronous motor;

[0039] In this embodiment, the linkage assembly 43 includes a linkage rod 431 installed at the top of the connecting shaft 44. The top of the linkage rod 431 is rotatably connected to the top of the inner cavity of the device box 311. A worm gear 432 is fixedly connected to the surface of the linkage rod 431, and the surface of the worm gear 432 meshes with the surface of the worm 42.

[0040] In this embodiment, an absolute encoder 6 is fixedly connected to the top of the device box 311. The output end of the absolute encoder 6 extends into the interior of the device box 311 and is fixedly connected to the top of the linkage rod 431.

[0041] The absolute encoder 6 uses a multi-turn absolute encoder for precise control of the gate's rotation angle;

[0042] In this embodiment, all electrical components are controlled by an external control system, which includes a PLC controller, a touch screen, and a wireless remote control. This system enables one-button operation for movement, lifting, rotation, and positioning, while also displaying real-time parameters of each component, such as position, angle, and load.

[0043] By setting up the rotating component 4, the rotating motor 41 drives the worm gear 42 to rotate. The worm gear 42 meshes with the worm wheel 432, driving the linkage rod 431 and the connecting shaft 44 to rotate, thereby causing the bearing plate 312 and the gate to rotate, realizing the adjustment of the hoisting angle. The absolute encoder 6 can monitor the rotation angle of the linkage rod 431 in real time, which facilitates precise control of the gate's rotation angle and further improves the positioning accuracy.

[0044] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0045] When using the precision positioning and hoisting device for the installation of the water conservancy gate, first drive the vehicle to a suitable position, fix the vehicle, and then adjust the height and angle of the main bridge body 1 according to the hoisting requirements.

[0046] Then, the mobile motor is started, which drives the moving screw to rotate, so that the moving seat 2 moves along the support arm to above the gate. Then, the controller starts the two sets of electric hoists 313 to work simultaneously, so that the hook 314 descends and hooks the gate. Then, the electric hoists 313 drive the gate to rise.

[0047] Subsequently, the drive motor 321 is started, which drives the bidirectional lead screw 322 to rotate, causing the two sliding plates 316 to move towards each other, and the sliding plates 316 to slide on the surface of the limiting rod 315. The sliding rod 317 drives the auxiliary positioning plate 318 to contact the two sides of the gate, thereby limiting and fixing the gate.

[0048] According to the installation angle requirements, the rotating motor 41 is started, which drives the worm 42 to rotate. The worm 42 meshes with the worm wheel 432, which drives the linkage rod 431, the connecting shaft 44 and the bearing plate 312 to rotate, thereby adjusting the angle of the gate. The absolute encoder 6 monitors the rotation angle in real time to ensure the angle is accurate.

[0049] After the adjustment is completed, the gate is moved to the installation position by the bridge-building body 1, and the electric hoist 313 is controlled to lower the gate to complete the installation.
