[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0039] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0040] Combine the following Figures 1 to 5 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute a limitation on the present invention.

[0041] like Figure 1 and Figure 2As shown, the present invention provides a pipe gallery hoist, comprising: a main beam body 100, a hydraulic cylinder 200 and a suspension rod 300, one end of the hydraulic cylinder 200 is evenly arranged on the main beam body 100, and the other end of the hydraulic cylinder 200 is connected to the suspension rod 300, and the suspension rod 300 is used to connect the pipe gallery body 110.

[0042] The hydraulic cylinders 200 are divided into at least three groups, each group of hydraulic cylinders 200 is connected in parallel and can be controlled individually, and the hydraulic cylinders 200 in each group are adjacent to each other and connected in series.

[0043] In other words, the main beam body 100 is connected to the hydraulic cylinder 200 , and the hydraulic cylinder 200 is connected to the pipe gallery body 110 through the suspension rod 300 .

[0044] Furthermore, since the hydraulic cylinders 200 are evenly installed on the main beam body 100 and the hydraulic cylinders 200 remain vertical to the main beam body 100 during operation, each hydraulic cylinder 200 in each group is subjected to the same force.

[0045] In an optional embodiment of the present invention, the pipe gallery hoist includes three groups of hydraulic cylinders 200 , wherein the first group includes 6 hydraulic cylinders 200 , the second group includes 6 hydraulic cylinders 200 , and the third group includes 8 hydraulic cylinders 200 .

[0046] Under actual working conditions, the hydraulic cylinders 200 in each group can be used simultaneously or individually. In other words, when hoisting an 8m pipeline corridor, the first group including 6 hydraulic cylinders 200, the second group including 6 hydraulic cylinders 200, and the third group including 8 hydraulic cylinders 200 are started simultaneously.

[0047] When hoisting a 4m pipe gallery, through the manual valve, the first group opens the 3 hydraulic cylinders 200 in the inner circle, the second group opens the 3 hydraulic cylinders 200 in the inner circle, and the third group opens the 4 hydraulic cylinders 200 in the inner circle. That is, only the middle 10 cylinders are used for hoisting.

[0048] Therefore, the pipe gallery hoist of the present invention can hoist pipe galleries of different sizes and has a wide range of uses.

[0049] like Figure 3 As shown, the hydraulic cylinders 200 are divided into at least three groups, which are equivalent to at least three force points. Since three points can determine a surface, at least three groups of hydraulic cylinders 200 can ensure that the pipe gallery body 110 is lifted horizontally.

[0050] Furthermore, a force sensor may be installed on each hydraulic cylinder 200 , and when the pipe gallery body 110 is lifted, real-time monitoring may be performed through a display screen connected to the controller.

[0051] like Figure 4As shown, in an optional embodiment of the present invention, the hydraulic cylinder 200 includes a cylinder body 201, a mounting seat 202 and a connecting seat 203, one end of the cylinder body 201 is connected to the mounting seat 202 through a first pin shaft 204, and the piston rod at the other end of the cylinder body 201 is connected to the connecting seat 203 through a second pin shaft 205.

[0052] The first pin shaft 204 and the second pin shaft 205 are arranged vertically.

[0053] In addition, the cylinder body 201 of the hydraulic cylinder 200 is inside the main beam body 100, saving height space.

[0054] In other words, the hydraulic cylinder 200 is connected to the main beam 100 through the mounting seat 202, and the piston rod of the hydraulic cylinder 200 is connected to the suspension rod 300 through the connecting seat 203. In terms of space, the first pin 204 and the second pin 205 are arranged in a cross shape.

[0055] By vertically arranging the first pin shaft 204 and the second pin shaft 205 , when the pipe gallery body 110 is lifted or hoisted, no matter whether the pipe gallery body 110 swings in the X direction or the Y direction, the suspension rod 300 will be adjusted according to the angle of the pipe gallery body 110 without damaging the pipe gallery body 110 .

[0056] Continue to refer Figure 4 In an optional embodiment of the present invention, the suspension rod 300 is a threaded rod, one end of the suspension rod 300 is connected to the connection seat 203 through a nut, and the other end of the suspension rod 300 passes through the hoisting hole of the pipe gallery body 110 and is connected to the pipe gallery body 110 through a nut. The height of the suspension device is reduced to save space.

[0057] Because the diameter of the gallery hoisting hole is only a dozen millimeters larger than the diameter of the boom, and there are many hoisting points, it is time-consuming to insert the boom with a traditional hanger. However, since the hydraulic cylinder 200 is hinged and can swing, it is easier to insert the boom 300 into the gallery hoisting hole.

[0058] Continue to refer Figure 1 In one embodiment of the present invention, the pipe gallery hoist further comprises a lifting lug 101, which is welded to the main beam 100. The main beam 100 has a through hole, and the hydraulic cylinder 200 is placed in the through hole, thereby reducing the space of the pipe gallery hoist.

[0059] Continue to view Figure 3 In another embodiment of the present invention, the main beam body 100 includes a first half main beam body 102 and a second half main beam body 103, and the first half main beam body 102 and the second half main beam body 103 are connected by bolts. The first half main beam body 102 and the second half main beam body 103 are symmetrical structures.

[0060] Furthermore, the first half main beam body 102 and the second half main beam body 103 are respectively provided with lifting ears 101 , and the positions of the lifting ears 101 are symmetrical and uniform.

[0061] like Figure 5 As shown, the present invention further provides a hydraulic system, including at least three groups of hydraulic cylinder control modules 400 , a hydraulic pump 401 and an oil tank 402 . The hydraulic cylinder control modules 400 are connected to the hydraulic pump 401 in parallel, and the oil tank 402 supplies oil to the hydraulic pump 401 .

[0062] In addition, the hydraulic cylinder control module 400 includes a plurality of the above-mentioned hydraulic cylinders 200 connected in series. Each hydraulic cylinder 200 is controlled by a stop valve.

[0063] Specifically, each group of hydraulic cylinder control modules 400 is connected in parallel. The hydraulic cylinders 200 in each group of hydraulic cylinder control modules 400 are connected in series end to end.

[0064] Alternatively, each group of hydraulic cylinder control modules 400 may be individually controlled through a stop valve.

[0065] Continue to refer Figure 5 In another embodiment of the present invention, the hydraulic cylinder control module 400 further includes a balancing valve group 410 and an electromagnetic reversing valve 411. The hydraulic cylinder 200 is connected to the balancing valve group 410, and the balancing valve group 410 is connected to the electromagnetic reversing valve 411. The balancing valve group 410 can balance the pressure of each group of hydraulic cylinders to balance the pressure, and also has the functions of maintaining and maintaining constant pressure.

[0066] In addition, the rodless chamber of the hydraulic cylinder 200 is connected to the pilot port of the balance valve group 410. The balance valve group 410 includes a balance valve and a check valve.

[0067] In another optional embodiment of the present invention, a stacked one-way throttle valve 412 is installed between the electromagnetic reversing valve 411 and the balancing valve group 410 .

[0068] In other words, the hydraulic oil flowing out of the electromagnetic reversing valve 411 is regulated by the superimposed one-way throttle valve 412 before entering the balancing valve group 410, and the hydraulic oil comes out of the rodless chamber of the hydraulic cylinder 200 and is regulated by the superimposed one-way throttle valve 412 before entering the electromagnetic reversing valve 411.

[0069] Furthermore, in one embodiment of the present invention, a cooler 413 and a filter 414 are installed at the oil return port of the oil tank 402 .

[0070] In addition, the hydraulic system further includes a relief valve 415 connected in parallel with the hydraulic cylinder control module 400 , and a two-position four-way electromagnetic reversing valve connected in parallel with the relief valve 415 .

[0071] Furthermore, the hydraulic pump 401 is a plunger pump and is driven by an electric motor. A one-way valve is installed at the oil outlet of the hydraulic pump 401 to prevent backflow.

[0072] The pipe gallery hoist provided by the present invention evenly arranges hydraulic cylinders on the main beam, and divides the hydraulic cylinders into at least three groups and connects them in parallel. The at least three groups of hydraulic cylinders can determine the level of the main beam, and the hydraulic cylinders in each group are connected in series to achieve the same force on each hydraulic cylinder, thereby realizing a pipe gallery hoist with a self-balancing function, which can minimize the damage during pipe gallery hoisting in a balanced state.

[0073] The working process of hoisting based on the above pipe gallery hoist and hydraulic system:

[0074] Connect the sling to the lifting equipment;

[0075] Reset all hydraulic cylinders to ensure that the piston rods of each hydraulic cylinder have the same extension length and the lower end surfaces of the booms are on the same plane;

[0076] Remove the nuts under the boom and raise the hanger to a certain height;

[0077] Move the lifting equipment so that the lifting rod is facing the lifting hole of the pipe gallery;

[0078] After alignment, lower the lifting equipment and insert the lifting rod into the lifting hole of the pipe gallery, ensuring that the insertion depth of the lifting rod into the lifting hole of the pipe gallery is consistent;

[0079] In the pipe gallery, tighten the nut so that the exposed screw length of the hanger rod is not less than 100mm;

[0080] Start the hydraulic pump of the pipe gallery hoist, and the red light in the three-color indicator will flash;

[0081] Start all groups of hydraulic cylinders at the same time so that each hydraulic cylinder is subjected to the same force;

[0082] Start the lifting equipment and make the pipe gallery 50mm to 100mm above the ground and keep it still; let the hydraulic lifting device self-balance the hydraulic cylinder until the pipe gallery is in a horizontal state;

[0083] Start the lifting equipment again and lift the pipeline gallery.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
