Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline installation, and in particular relates to a device and method for suspending pipelines in a confined space. Background Art

[0002] In the fields of building construction, municipal engineering, etc., there are many indoor pipeline installation situations. Some pipelines are located in confined spaces such as large basements, corridors, pools or boxes. The installation height is relatively high, and the space in the confined space is limited. Many conventional methods cannot be implemented, and the operation is difficult.

However, these devices are impractical in some confined spaces. Furthermore, installation typically occurs after civil engineering is complete, and installation is not possible before the structure is sealed. Currently, pipeline installation in confined spaces primarily relies on manual handling, hand winches, and platform erection, resulting in low efficiency, high labor costs, and a lack of comprehensive installation equipment or methods for the entire process.

[0025] This patent can achieve the following beneficial effects:

[0026] The confined space suspension pipe device provided by the present invention is advantageous for use under space-constrained conditions, because generally pipe hooks are required for lifting pipes, but the pipe hooks must ensure that the pipes are in a horizontal state when lifting. In the case of limited space, for example, when lifting the pipes into a basement, the pipe hooks cannot play their role because the basement entrance is small and the pipes must be lifted vertically. The present invention designs a pipe lifting guard for loading pipes, which, in conjunction with self-made non-standard lifting equipment, can complete the lifting work under space-constrained conditions. When installing the pipe lifting guard, there is no need to lift the pipe again. It is only necessary to put the pipe lifting guard on the upper part of the pipe, install the detachable support rod, and then roll the pipe lifting guard. The installation is simple and labor-saving.

[0027] Additionally, the arc-shaped plate facilitates manual rotation of the pipe hoisting frame, allowing it to flip 180°. The universal ball joint facilitates manual pushing of the pipe hoisting frame, allowing for position adjustment. The rollers shift the frame when tilted, preventing it from being dragged.

DETAILED DESCRIPTION

[0053] The preferred solution is Figures 1 to 23 As shown, a device for suspending pipes in a confined space includes a pipe transport device 16, a pipe lifting guard frame 17, a vertical lifting device and a hydraulic lift 18; the pipe transport device 16 includes two wheelbarrows, which are used to transport pipes in combination; the pipe lifting guard frame 17 includes two curved plates 17.1, a plurality of support rods are provided between the two curved plates 17.1, a flat groove 17.2 is opened in the middle of the curved plate 17.1, a plurality of universal balls 17.3 are provided in the flat groove 17.2, a roller frame 17.4 is provided on the side of the curved plate 17.1, and a roller 17.5 is provided on the roller frame 17.4; the pipe lifting guard frame 17 is used to be installed on the outside of the pipe, and the vertical lifting device is used to lift the pipe lifting guard frame 17 and the pipe inside the pipe lifting guard frame 17; the hydraulic lift 18 includes at least two units, and the hydraulic lift 18 is provided with an auxiliary tire frame 19.

[0054] The pipe hoisting guard 17 is designed to provide a loading tool for pipes. Pipe hooks are typically used for lifting pipes, but they must maintain a horizontal position. This is particularly problematic in limited space, such as when lifting pipes into a basement, where the entrance is small and the pipe must be hoisted vertically. The present invention provides a pipe hoisting guard 17 for loading pipes. Combined with custom-made, non-standard lifting equipment, this can facilitate lifting operations in confined spaces.

[0055] Specifically, the curved plate 17.1 of the pipe hoisting support frame 17 is an arc-shaped plate with an arc angle greater than 180°, preferably 270°. The support rods include at least two detachable support rods 17.6 and one fixed support rod 17.7, with the two detachable support rods 17.6 being mounted at both ends of the curved plate 17.1. A reinforcement frame 17.8 is provided on the curved plate 17.1, and a lifting lug 17.9 is provided on the reinforcement frame 17.8.

[0056] After removing the two detachable support rods 17.6, the pipe lifting guard 17 can be sleeved on the pipe from above, and then the detachable support rods 17.6 can be installed. The detachable support rods 17.6 can prevent the pipe from rolling out of the pipe lifting guard 17. The fixed support rods 17.7 are rods that are not frequently removed and are generally designed to be two or more.

[0057] The arc-shaped plate 17.1 facilitates manual rotation of the pipe hoisting frame 17, allowing it to flip 180°. The universal ball 17.3 facilitates manual pushing of the pipe hoisting frame 17, allowing it to adjust its position. The roller 17.5 shifts the pipe hoisting frame 17 when it tilts, preventing it from being dragged.

[0058] Furthermore, the vertical lifting device includes at least two retractable supports, a column 1 is detachably provided on the top of the retractable support, a secondary beam 2 is detachably provided on the top of the column 1, the secondary beam 2 is detachably connected to the main beam 3, a pulley 4 is provided on the main beam 3, the pulley 4 is matched with the lifting rope 5, one end of the lifting rope 5 is connected to the hook 6, and the other end of the lifting rope 5 is connected to the winch 7; the retractable support includes a first bracket 8 and a second bracket 9, a first cross bar 10 is provided on the first bracket 8, and a second cross bar 11 is provided on the second bracket 9, the first cross bar 10 and the second cross bar 11 are slidably matched with each other, and the first cross bar 10 and the second cross bar 11 are fixed by a limit member 12.

[0059] The vertical lifting device provided by the present invention includes five major parts: a lifting drive component, a telescopic support, a column 1, a secondary beam 2 and a main beam 3. It can be temporarily assembled in places where space is limited; the main beam 3 can be made of H-shaped steel, the secondary beam 2 and the column 1 can be made of square steel pipes, and flange plates are welded at the upper and lower ends of the column 1; the telescopic support is welded with square steel, and the telescopic support can be extended or retracted, which is conducive to transportation in places where space is limited.

[0060] This solution includes two retractable supports, each topped with two columns 1. A secondary beam 2 is positioned between the two columns 1. Secondary beam 2 is provided with a slot 2.1, which houses a main beam 3. Both slot 2.1 and main beam 3 have bolt holes, and slot 2.1 is secured to main beam 3 via bolts. The columns 1 are connected to the retractable supports via flange plates, and the columns 1 are connected to the secondary beam 2 via flange plates.

[0061] The first crossbar 10 is inserted into the second crossbar 11; the first crossbar 10 is provided with a first slide 13, and the second crossbar 11 is provided with a second slide 14. The first slide 13 is provided with a limit groove 15 at both ends, and the second slide 14 is provided with a limit groove 15 at one end; the limit member 12 includes a slide bar 12.1, and the slide bar 12.1 is provided with a limit plate 12.2, and the limit plate 12.2 is used to cooperate with the limit groove 15. The first crossbar 10 and the second crossbar 11 are square steel pipes. The reason why the first crossbar 10 and the second crossbar 11 are not connected by bolts is that the bolts easily slide between the first slide 13 and the second slide 14. If the bolts are over-tightened to improve the stability of the connection, the first crossbar 10 and the second crossbar 11 may be deformed. Therefore, a limit member 12 with a limit function is used to cooperate with the first slide 13, the second slide 14 and the limit groove 15.

[0062] The slide bar 12.1 is provided with an external thread 12.3, which is connected to the nut 12.4. An upper baffle 12.5 and a lower baffle 12.6 are respectively provided at the upper and lower ends of the slide bar 12.1.

[0063] The operating principle of the limiting member 12 is as follows: rotating the nut 12.4 adjusts the height of the limiting plate 12.2. When the limiting plate 12.2 disengages the limiting slot 15, the relative position of the first crossbar 10 and the second crossbar 11 can be adjusted. When the first crossbar 10 and the second crossbar 11 overlap, they are in the retracted state, and when they are fully extended, they are in the extended state. When the nut 12.4 is rotated upward and disengaged from the external thread, the slide bar 12.1 drops, the limiting plate 12.2 drops, the upper baffle 12.5 becomes the support point of the entire limiting member 12, and the limiting plate 12.2 disengages from the limiting slot 15, retracting the first crossbar 10. Rotating the nut 12.4 causes the slide bar 12.1 to rise. When the lower baffle 12.6 contacts the second crossbar 11, it rotates into place, and the limiting plate 12.2 is located in the limiting slot 15.

[0064] Furthermore, the hydraulic lift 18 is a hydraulic scissor lift, and an auxiliary tire frame 19 is provided on the lifting platform of the hydraulic scissor lift. The auxiliary tire frame 19 includes an arc-shaped slot, and the arc-shaped slot is used for placing pipes.

[0065] Furthermore, the wheelbarrow includes an arc-shaped support plate, a wheel is provided at the bottom of the arc-shaped support plate, the arc-shaped support plate is connected to a handrail, and a support column is provided at the bottom of the handrail.

[0066] Preferably, the method for hoisting a suspended pipe device in a confined space comprises the following steps:

[0067] S1: If Figure 3 As shown, a vertical lifting device is set up in advance at the lifting position, such as Figure 22 As shown, the pipeline is transported to the operation site using a pipeline transport device 16;

[0068] S2: If Figure 5 As shown, remove the two detachable support rods 17.6 of the pipe lifting guard 17, and sleeve the pipe lifting guard 17 on the pipe from top to bottom;

[0069] S3: If Figure 6 As shown, reinstall the detachable support rod 17.6 so that the pipeline hoisting guard 17 covers the pipeline;

[0070] S4: As Figure 7 As shown, the pipe hoisting frame 17 is rolled so that the pipe hoisting frame 17 drives the pipe to roll together, so that the flat groove 17.2 faces the ground, and the universal ball 17.3 serves as the support point of the entire pipe hoisting frame 17;

[0071] S5: If Figure 8-9 As shown, push the pipeline hoisting frame 17 to transport the pipeline to the vicinity of the hoisting hole, and connect the hook 6 with the lifting lug 17.9;

[0072] S6: As Figure 10-11As shown, the winch 7 is turned on to slowly lift the pipe hoisting guard frame 17. During the tilting process, the universal ball 17.3 slowly leaves the ground, and the roller 17.5 contacts the ground. The roller 17.5 serves as the support point of the pipe hoisting guard frame 17. The pipe hoisting guard frame 17 is pulled by the winch 7 and gradually approaches the hole until the pipe hoisting guard frame 17 is completely lifted vertically.

[0073] S7: As Figure 12 As shown, the pipe lifting guard frame 17 is lowered. After the pipe lifting guard frame 17 contacts the ground, the pipe lifting guard frame 17 changes from a vertical state to an inclined state. The rollers 17.5 support the pipe lifting guard frame 17 and move the pipe lifting guard frame 17 to one side until the pipe lifting guard frame 17 is completely leveled.

[0074] S8: Move the pipe lifting guard frame 17 to the auxiliary tire frame 19, rotate the pipe lifting guard frame 17 so that one end of the flat groove 17.2 of the pipe lifting guard frame 17 faces upward, remove the detachable support rod 17.6, and then remove the pipe lifting guard frame 17;

[0075] S9: As Figure 23 As shown, the hydraulic lift 18 is turned on to move the pipeline upward, and then the pipeline is installed on the pipeline hanger, completing the pipeline lifting work.

[0076] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. In other words, equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
