Principle details of the present embodiment:

A lifting tool for accurately installing a hydraulic oil pipe of a sluice comprises a portal frame 1, wherein the portal frame 1 mainly comprises a cross beam and upright posts standing at two ends of the cross beam, and rib posts are arranged on the upright posts to strengthen and support the upright posts. The beam of the portal frame 1 is provided with a hoist lifting appliance 2, the hoist lifting appliance 2 is erected on a movable frame, the movable frame is provided with guide wheels, and the guide wheels are driven by a motor to further control the hoist lifting appliance 2 to move along the beam. The hoist lifting appliance 2 comprises an upper lifting hook, a winding mechanism, a lower lifting hook 5 and a lifting chain. Wherein the upper lifting hook is hung on the movable frame.

The hoisting chain of hoist 2 stretches out the end and is connected with hanging frame 3, and hanging frame 3 both sides all are equipped with hangers 4, and lower lifting hook 5 hangs on hanging frame 3 diapire, and two stand inboard of portal frame 1 all are equipped with guide rail 6, and equal vertical slidable mounting has heavy burden 7 on two guide rails 6, all is equipped with the link on two heavy burden 7, and the link is hooked with connecting rope 9, and two connecting rope 9 other ends are hooked with hanger 4 of homonymy respectively.

When in use, the oil pipe is hung to the installation position by the automobile crane and then is transferred to the device. The lower lifting hook 5 lifts the oil pipe to lift and transfer, in the lifting process, the load 7 moves along the guide rail 6, and the two load 7 pull the lifting frame 3 through the connecting rope 9, so that the lifting frame 3 is limited, the stability in the transferring process is further improved, the shaking probability of the oil pipe is reduced, the oil pipe is more accurate in installation and butt joint, the oil pipe is not shaken, the installation and butt joint are faster, and the installation efficiency is improved.

In a further embodiment of the scheme, the hoist lifting device 2 is any one of a chain block or an electric block, and can realize the lifting of the oil pipe.

In a further embodiment of the present solution, the load 7 is sleeved on the guide rail 6. The load 7 is provided with a through hole and is sleeved on the guide rail 6, and the diameter of the through hole is larger than the size of the guide rail 6 so as to leave a gap and avoid clamping.

In a further embodiment of the solution, the guide rail 6 is detachably mounted on the gantry 1. The guide rail 6 is C-shaped, one end of the guide rail 6 is a cylindrical end, a stud is rotatably arranged at one end of the guide rail, and jacks and threaded holes are vertically arranged on the upright post of the portal frame 1 at intervals. When the guide rail 6 is installed, the cylindrical end is aligned with the jack, the stud is aligned with the threaded hole, the stud is screwed into the threaded hole by screwing the stud, and the cylindrical end is also inserted into the jack, so that the guide rail 6 is installed on the upright post. The guide rail 6 can be detachably installed, and is convenient to maintain and replace. And for the fastening of guide rail 6 both ends on the stand through a plurality of fasteners, when driving the structure installation like this, only need twist one, the installation is more convenient light.

The heavy load 7 is used for traction limiting, and for a large sluice, the oil pipe is large in size and heavy in weight, so that the heavy load 7 on the other side of the heavy load is still likely to deviate to one side due to gravity center deviation, and the heavy load 7 on the other side of the gravity center deviation direction slides upwards to be straightened for traction. Although the limit can still be pulled finally, small-amplitude shaking still occurs. Therefore, in this embodiment, a structure is provided instead of the weight-bearing structure 7. The bottom ends of the upright posts on two sides of the portal frame 1 are respectively provided with a winch 8, a traction rope 10 is wound on a reel of each winch 8, a hook is arranged at the extending end of each traction rope 10, and the hooks are connected with the corresponding side hanging lugs 4. The winch 8 is used for winding or loosening in real time along with the pulling state, so that the hanging frame 3 is always in a vertical stretching state no matter in the lifting or moving process, and the device is more intelligent (if moving to the left, the left winch 8 winds the pulling rope 10, the right winch 8 releases the pulling rope 10, and the pulling rope 10 is always stretched. And because hoist engine 8 does not remove, then the traction point is motionless to make the restriction more firm, can not be because of the swing of the removal of hanging frame 3, can improve the steadiness of hoist and mount more, avoid hoist and mount to rock, improve oil pipe's installation accuracy.

In a further embodiment of the scheme, the hoist lifting appliance 2 is selected to be an electric hoist, the portal frame 1 is provided with a control box 11, and the control box 11 is electrically connected with controllers of the two hoists 8, the electric hoist and the motor. The control box 11 is electrically connected with a remote controller 12, the remote controller 12 is shown in fig. 6, the upper end and the lower end of the remote controller 12 are respectively provided with an emergency stop button and a switch knob, four paired buttons are vertically arranged in the middle at intervals, and the buttons correspond to the winding and loosening buttons of the two windlass 8 and the electric hoist and the motor advancing and retreating buttons of the movable frame respectively. Through this remote controller 12, can the manual control multiunit electronic equipment, and it is clear for the operation is more convenient, convenient. The switch knob is turned on and off, so that locking capability is improved, the electric equipment is prevented from being started due to false collision and collision, and the equipment is started only after the switch knob is turned on, so that use safety is improved.

The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, shall cover the scope of the present application by equivalent substitution or modification according to the technical scheme of the present application and the application concept thereof.
