Description

Technical Field

[0001] The present application relates to the technical field of lifting equipment, and in particular to a lifting tool for precise installation of a hydraulic oil pipe for a sluice. Background Art

[0002] Sluice gates are important control structures in the water conservancy engineering system and are one of the main means of dispatching floods and ensuring the supply of water resources. In many sluice gate projects, hydraulic hoists are widely used. However, during the daily inspection and maintenance of the oil pipeline, maintenance personnel often find oil leakage in the return oil pipeline valve group joints, tees, etc., which poses a serious threat to the safe operation of the sluice gate. For this reason, a vacuum breaker valve is installed on the return oil main pipe to block the siphon phenomenon, slow down the oil leakage, and reduce the blockage and overflow in the return oil pipe. However, there are still many pipelines that cannot be used anymore, so they need to be disassembled and replaced.

[0003] When disassembling and assembling the oil pipe, lifting equipment is used in most cases. Traditional lifting equipment mainly includes hangers and hoists (hoisting equipment). After being tied with straps, the oil pipe is lifted by the hoisting equipment and then transferred to reduce the burden of manpower handling. However, there are certain problems with this use during installation. Ordinary hoists have a hook head. During the process of carrying the oil pipe, the oil pipe will inevitably shake, especially when the oil pipe is docked, the shaking will affect the installation process and docking accuracy.

[0004] To this end, the present application provides a lifting tool for the precise installation of the hydraulic oil pipe of a sluice gate, which solves the problem of shaking of the oil pipe caused by traditional lifting tools. Utility Model Content

[0024] The following will be combined with the attached examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0025] In order to solve the problems existing in the prior art, the present embodiment provides a lifting tool for the precise installation of the hydraulic oil pipe of a sluice gate, including a gantry 1, a movable hoist sling 2 is provided on the crossbeam of the gantry 1, the protruding end of the lifting chain of the hoist sling 2 is connected to a lifting frame 3, a lower hook 5 is provided at the lower end of the lifting frame 3, and hanging ears 4 are provided on both sides, guide rails 6 are provided on the inner sides of the two columns of the gantry 1, weights 7 are vertically slidably installed on the two guide rails 6, and connecting ropes 9 are hooked on the two weights 7, and the other ends of the two connecting ropes 9 are respectively connected to the hanging ears 4 on the same side.

[0026] Principle details of this embodiment:

[0027] A lifting tool for precise installation of hydraulic oil pipes for water gates, comprising a gantry 1, which is mainly composed of a crossbeam and columns erected at both ends of the crossbeam, and ribs are arranged on the columns to reinforce the support. A hoist sling 2 is arranged on the crossbeam of the gantry 1, and the hoist sling 2 is mounted on a mobile frame, and the mobile frame is provided with a guide wheel, which is driven by a motor to control the hoist sling 2 to move along the crossbeam. The hoist sling 2 comprises an upper hook, a winding mechanism, a lower hook 5, and a lifting chain. The upper hook is hoisted on the mobile frame.

[0028] The protruding end of the lifting chain of the hoist 2 is connected to a hanging frame 3, and hanging ears 4 are provided on both sides of the hanging frame 3. The lower hook 5 is suspended on the bottom wall of the hanging frame 3. Guide rails 6 are provided on the inner sides of the two columns of the gantry 1, and weights 7 are vertically slidably installed on the two guide rails 6. Both weights 7 are provided with hanging rings, and connecting ropes 9 are hooked on the hanging rings. The other ends of the two connecting ropes 9 are respectively hooked with the hanging ears 4 on the same side.

[0029] When in use, the oil pipe is lifted to the installation site by a car crane and then transferred to the device. The lower hook 5 lifts the oil pipe and is lifted and transferred. During the lifting process, the weight 7 moves along the guide rail 6, and the two weights 7 pull the hanging frame 3 through the connecting rope 9, thereby restricting the hanging frame 3, thereby improving the stability during the transfer process and reducing the probability of oil pipe shaking, so that the oil pipe installation and docking are more accurate; without shaking, the installation and docking are also faster, and the installation efficiency is improved.

[0030] In a further embodiment of the present solution, the hoist 2 is any one of a hand chain hoist and an electric hoist, both of which can realize the hoisting of the oil pipe.

[0031] In a further embodiment of the present invention, the weight 7 is sleeved on the guide rail 6. The weight 7 is provided with a through hole and sleeved on the guide rail 6, and the diameter of the through hole is larger than the size of the guide rail 6 to leave a gap to avoid jamming.

[0032] In a further embodiment of the present scheme, the guide rail 6 can be detachably mounted on the gantry 1. The guide rail 6 is C-shaped, with one end of the guide rail 6 being a cylindrical end and the other end being rotatably mounted with a stud. The columns of the gantry 1 are provided with plug holes and threaded holes at vertical intervals. During installation, the cylindrical end is aligned with the plug hole, the stud is aligned with the threaded hole, the stud is screwed and tightened into the threaded hole, and the cylindrical end is also inserted into the plug hole, thereby installing the guide rail 6 on the column. The guide rail 6 can be detachably installed, which is convenient for maintenance and replacement. And compared with fastening the two ends of the guide rail 6 to the column through multiple fasteners, when the driving structure is installed, only one needs to be screwed, and the installation is more convenient and easy.

[0033] In a further embodiment of the present scheme, the guide rail 6 can also be a C-shaped tube, and the openings of the two C-shaped tubes are both facing the hoist sling 2. At this time, the weight 7 is a steel ball, and the steel ball-shaped weight 7 is embedded in the C-shaped tube, and the connecting rope 9 extends from the opening of the C-shaped tube.

[0034] The weight 7 is used to pull and limit the position. For large sluice gates, the oil pipe is large in size and heavy in weight. Then, it may still deviate to one side due to the deviation of the center of gravity. At this time, the weight 7 on the other side of the deviation direction will slide upward and straighten to pull. Although the pull and limit can still be achieved in the end, there is still a small amount of shaking. Therefore, in this embodiment, another structure is set to replace the weight 7 structure. A winch 8 is provided at the bottom end of the columns on both sides of the gantry 1. A pulling rope 10 is wound on the reel of the winch 8. A hook is provided at the protruding end of the pulling rope 10, and the hook is connected to the corresponding side hanging ear 4. The winch 8 is wound or released in real time according to the pulling state, so as to ensure that the hanging frame 3 is always in a vertical straight state regardless of whether it is lifting or moving, which is more intelligent (such as moving to the left, the left winch 8 winds up the pulling rope 10, and the right winch 8 releases the pulling rope 10, and the pulling rope 10 is always straight). And because the winch 8 does not move, the pulling point does not move, so that the restriction is more stable and will not swing due to the movement of the hanging frame 3, which can further improve the stability of the hoisting, avoid hoisting shaking, and improve the installation accuracy of the oil pipe.

[0035] In a further embodiment of this scheme, the hoist 2 is selected as an electric hoist, and a control box 11 is provided on the gantry 1. The control box 11 is electrically connected to the controllers of the two hoists 8, the electric hoist, and the motor. The control box 11 is electrically connected to a remote controller 12. The remote controller 12 is shown in the attached figure. Figure 6 As shown, the upper and lower ends are respectively provided with an emergency stop button and a switch knob, and the middle part is provided with four groups of paired buttons at vertical intervals, which correspond to the two winches 8, the winding and releasing buttons of the electric hoist, and the forward and backward buttons of the motor of the mobile frame. Through the remote control 12, multiple groups of electric equipment can be manually controlled, and the operation is clear and convenient. The switch knob is turned to open and close, which increases the locking ability and avoids the electric equipment from being started by accidental contact or bumping; the equipment is started only after the switch knob is turned, which improves the safety of use.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
