When the operator uses the hoisting device 91, the operator controls the crown block 9 to move to the position above the object to be hoisted, then manually surrounds and fixes the hoisting member 911 to the object to be hoisted, and finally controls the crown block 9 to transversely transport the object to a preset position. In the operation process, when the object to be hung is fixed on the hanger 911, the object to be hung needs to be wound and positioned by manpower, which is laborious and time-consuming, and accidents are easily caused by careless operation, so the hoisting device 91 needs to be improved.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 4, 5 and 6, an embodiment of the pipe hanging device of the present invention is suitable for being installed on a crown block a and used for hanging and transferring at least one pipe 90 (see fig. 9), and the embodiment includes a lifting unit 1 connected to the lower part of the crown block a and capable of longitudinally extending and retracting, a connecting unit 2 disposed at the bottom of the lifting unit 1 and spaced from the crown block a, a plurality of clamping units 3 erected below the connecting unit 2 and spaced from each other transversely, a linking unit 4 installed between the connecting unit 2 and the clamping unit 3, a driving unit 6 electrically connected to the clamping unit 3, a rolling unit 5 located between the crown block a and the lifting unit 1, and a control unit 7 in information connection with the driving unit 6 and the rolling unit 5.

First, the present embodiment is described in an environment where the operation space is limited by the floor space of the factory according to the pipe pickling plant, and the main embodiment is a case where one or more pipes 90 are transported and put into a pickling tank B (shown in fig. 10 and 11).

In this embodiment, the connecting unit 2 is specifically a bracket extending horizontally in the transverse direction, and can move longitudinally relative to the crown block a along with the longitudinal extension and contraction of the lifting unit 1. The connection unit 2 comprises a front end 21 and a rear end 22 which are respectively arranged at two opposite sides along the transverse direction, and a horizontal corrector 23 which is in information connection with the lifting unit 1 and is used for recording a horizontal parameter. A reference line L is defined in advance, which is connected to the front end 21 and the rear end 22. Specifically, the front end 21 and the rear end 22 of the connection unit 2 are defined by opposite ends of the connection unit 2 extending along the reference line L.

The lifting unit 1 comprises two telescopic booms 11 which are arranged between the front end 21 and the rear end 22 of the connecting unit 2 at intervals and extend longitudinally. The telescopic booms 11 may be respectively extended and retracted up and down by different lengths, or may be extended and retracted up and down by the same length, and are mainly used to adjust the distances between the front end 21 and the rear end 22 of the connection unit 2 and the crown block a, respectively, so that the connection unit 2 may be changed in different inclination directions.

Each clamping unit 3 includes two spaced gripping members 31 for cooperating with each other to position at least one pipe 90, two adjusting members 32 respectively disposed between the gripping members 31 and the connecting unit 2 for adjusting the distance between the gripping members 31, and two outer coating layers 33 respectively covering the gripping members 31 and made of corrosion-resistant polypropylene (PP) plastic. Each gripping member 31 has a downwardly extending arm portion 311 and a hooking portion 312 extending transversely from the bottom end of the arm portion 311. The adjusting member 32 is driven to adjust the opening distance between the gripping members 31 according to the diameter and width of the pipe 90. A virtual line L' is defined, which projects from the reference line L to the same plane as the hooking part 312 and is parallel to the reference line L.

As shown in fig. 6, 10 and 11, in this embodiment, the pipe 90 is put into the pickling tank B, and the gripping member 31 carrying the pipe 90 is likely to be corroded and damaged by the pickling material during transportation, so the outer coating layer 33 needs to be coated to prevent the gripping member 31 from directly contacting the pickling material, and to prolong the service life of the gripping member 31.

The linkage unit 4 is disposed below the connection unit 2 and is a linkage mechanism, which generally includes a transmission rod 41 and two driven rods 42, each driven rod 42 is connected to a corresponding clamping member 31, and the rest clamping members 31 are connected to the transmission rod 41. When the gripping members 31 located on the transmission rod 41 start to actuate, the transmission rod 41 transmits power to the driven rod 42, so that the gripping members 31 connected to the driven rod 42 actuate synchronously.

Referring to fig. 7 and fig. 4, in the present embodiment, the control unit 7 is a central control module capable of transmitting a control signal, the driving unit 6 is a motor providing operation power, and the scrolling unit 5 is two windlasses respectively used for adjusting the lifting height of the lifting unit 1, but the specific implementation and equipment selection are not limited thereto. The control unit 7 is used for controlling the crown block a, the driving unit 6 and the scrolling unit 5, the crown block a is controlled by the control unit 7 to move along the front-back direction and the left-right direction, the driving unit 6 can drive the arm part 311 and the hooking part 312 to rotate at a longitudinal rotating shaft at the same time by an angle, and the scrolling unit 5 can scroll to enable the lifting unit 1 to move up and down and to enable the connecting unit 2 to tilt at an angle in a linkage manner, so that a user can move to a target position through the crown block a, the scrolling unit 5 and the driving unit 6 in multiple directions only by remotely operating the control unit 7.

Referring to fig. 8 and 9 in conjunction with fig. 4, the clamping of a pipe 90 to be processed by the present embodiment is described. The hooking portion 312 and the arm portion 311 of the clamping member 31 are driven to move between a first position and a second position, in the first position, the clamping member 31 is displaced along a direction parallel to the reference line L, and the hooking portions 312 face the same direction and are spaced apart from each other. In the second position, the ends of the hooking portions 312 facing each other are adjacent to each other along a direction parallel to the reference line L, and are capable of cooperatively carrying the pipe 90 to be processed. It should be added that the hooking portion 312 and the arm portion 311 of the gripping member 31 can be driven to change between the first position and the second position, and a member electrically connected to the driving unit 6, specifically a pivot, is used to rotate the gripping member 31 connected to the pivot around the pivot, but in practice, the gripping member 31 can be rotated in the same manner, and the invention is not limited thereto.

As shown in fig. 4, five groups of clamping units 3 perpendicular to the connecting unit 2 are illustrated in the embodiment as an example, and the spacing distance between each group of clamping units 3 is equal, but in the actual implementation of the embodiment, the number of the clamping units 3 may be increased or decreased according to the size of the factory or the stacking amount of the pipes 90 to be processed. In addition, the arm 311 and the hook 312 of each gripper 31 are arranged in a staggered manner in front and back as shown in fig. 8, so that the grippers 31 can be more stable when fixing and conveying the pipe 90 to be processed.

Referring to fig. 9 and fig. 4 and 5, in actual operation, an operator may first operate the crown block a to move transversely to the placement area of the pipe 90 to be processed, and control the adjusting member 32 as shown in fig. 5, first open the gripping members 31 in a direction away from each other to be greater than the diameter width of the pipe 90 to be processed and to reserve a margin distance, and then the hooking portion 312 of the gripping member 31 is located at the first position. Then, the telescopic boom 11 is controlled to extend downwards at the same time, so that the hooking portion 312 is located at the bottom end of the pipe 90 to be processed, and in the process of controlling the hooking portion 312 to descend, the distance between the clamping members 31 needs to be finely adjusted to reach an opening distance which does not collide with the pipe 90 to be processed and does not occupy a working space. The driving unit 6 drives the gripping member 31 to rotate the hooking portion 312 to the second position, and controls the adjusting member 32 to make the gripping member 31 approach each other to hold and fix the pipe 90 to be processed, so as to carry the pipe 90 to be processed.

Referring to fig. 8 to 10, when the hooking portion 312 is at the first position, an included angle between the virtual line L 'and the hooking portion 312 is 0 degree, when the hooking portion 312 rotates to the second position, the included angle between the virtual line L' and the hooking portion 312 is 90 degrees, a rotatable angle of the hooking portion 312 is any one of 0 to 90 degrees, and the operator adjusts the hooking portion 312 to rotate to a required angle according to the shape and arrangement of the pipes 90 to be processed, so that the pipes 90 to be processed can be stably fixed between the clamping members 31. This gripping method is useful for reducing the working space when the opening distance of the gripping member 31 is set in accordance with the specification of the pipe 90 to be processed. In response to the shaking of the telescopic boom 11 during the up-and-down movement, the relative position where the hooking portion 312 and the pipe 90 to be processed are parallel to each other is relatively less prone to collision, so that the pipe 90 to be processed can be closer to the opening distance than the manner that the clamping jaw 933 needs to be opened horizontally as shown in fig. 3, and the operation space can be more reduced.

Referring to fig. 10 and 11, the first end of the connection unit 2 immersed in the liquid is the front end 21 and the rear end 22, respectively, to illustrate the efficacy of the present embodiment. When the overhead traveling crane a carries the pipe fitting 90 to be processed to the top of the pickling tank B, the connection unit 2 is in a horizontal state, if the pipe fitting 90 to be processed is directly immersed in the pickling tank B, the pickling solution can instantly and simultaneously flow into the pipe fitting 90 to be processed from both ends of the pipe fitting 90 to be processed, so that a turbulent effect is easily generated to cause the pipe fitting 90 to be processed to slide down or separate from the clamping member 31, at this time, the operator firstly makes the telescopic boom 11 respectively extend and retract for different distances to make the connection unit 2 in an inclined state, as shown in fig. 10, the front end 21 of the connection unit 2 is lower than the rear end 22, or as shown in fig. 11, the rear end 22 of the connection unit 2 is lower than the front end 21, thereby respectively taking the front end 21 and the rear end 22 as solution inlet ends and moving towards the pickling tank B to immerse the pipe fitting 90 to be processed, the pickling solution will slowly flow into the pipe 90 to be treated along the solution inlet direction, so as to reduce the occurrence of turbulent flow effect.

Referring to fig. 10 and 11 in conjunction with fig. 7, after the pipe 90 to be treated is immersed, the telescopic boom 11 is simultaneously retracted upward by a length to take the pipe 90 to be treated away from the pickling tank B, and at this time, the connection unit 2 is still in the inclined state, and the operator transfers the control signal via the control unit 7, so that the driving unit 6 drives the scrolling unit 5 and drives the telescopic boom 11 to actuate, and triggers the horizontal parameter recorded by the horizontal corrector 23, and further moves the connection unit 2 back to the horizontal state from the inclined state, so that the pipe completing the pickling operation can be transported to a pre-placing area, and the pipe 90 to be treated of the next batch can be subsequently pickled.

However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereto, and all the simple equivalent changes and modifications made according to the claims and the contents of the specification should be included in the scope of the present invention.
