Description

Technical Field

[0001] The present invention relates to the technical field of building pipeline transportation, in particular to a pipeline transportation vehicle suitable for use in a narrow space of a building. Background Art

[0002] During the construction process, there are situations where various types of pipelines need to be transported. The larger the diameter and the longer the length of the pipeline, the more difficult it is to transport it. In addition, for areas with narrow space for pipeline installation, for example, when pipelines need to be installed in a building mezzanine, the transportation of the pipeline is greatly inconvenient due to the small space, complex pipeline layout, and the presence of pipeline supports in the space. At the same time, for some heavy pipelines such as cast iron pipes and galvanized steel pipes, it is difficult for one or two people to carry and install them. Even if a two-person carrying method is adopted, the workers' physical strength will decline seriously during the transfer and installation operation due to the long carrying time, thereby affecting work efficiency. In addition, fatigue work in a narrow and confined space is prone to safety accidents. In response to the above-mentioned problems, the present invention proposes a pipeline transport vehicle suitable for use in narrow spaces in buildings. Summary of the Invention

[0003] The purpose of the present invention is to solve the defects in the prior art and to propose a pipeline transport vehicle suitable for use in narrow spaces of buildings.

[0010] The lifting assembly includes two U-shaped vertical guide rails fixed to the top surface of the base, an annular guide rail is fixed to the upper ends of the two U-shaped vertical guide rails, and a plurality of sliding brackets are slidably provided in the annular guide rails, and a double-sided gear ring is installed on the upper ends of the sliding brackets;

[0011] The inner sides of the two U-shaped vertical guide rails are each equipped with a screw rod for vertical rotation. The two sides of the lifting seat extend into the two U-shaped vertical guide rails respectively and are threadedly installed with the screw rod on the same side. The upper ends of the two screw rods extend to the upper side of the U-shaped vertical guide rail and are respectively equipped with driven gears.

[0012] Furthermore, the annular guide rail includes two limit rings arranged in parallel above and below, and a slideway is formed between the two limit rings. The sliding bracket has an L-shaped structure, and the lower end of the sliding bracket is slidably arranged in the slideway between the limit rings, and the upper end is fixed on the lower surface of the bilateral gear rings.

[0013] Furthermore, there are multiple anti-slip positioning components, and the multiple anti-slip positioning components are symmetrically arranged on both sides of the inner wall of the U-shaped support frame.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0032] Reference Figure 1-8 A pipeline transport vehicle suitable for use in a narrow space of a building comprises a base 1, a plurality of universal wheels 2 are installed around the base 1, a sleeve 4 is fixed to the upper side of the base 1 through a plurality of support rods 3, a push rod 5 is fixed to the side of the sleeve 4, and a handle 6 is installed at the end of the push rod 5 away from the sleeve 4;

[0033] A vertical shaft 7 is vertically inserted into the center of the sleeve 4, and a lifting assembly 9 is provided on the upper side of the base 1, and the lifting assembly 9 is connected to the lower end of the vertical shaft 7;

[0034] A U-shaped support frame 8 is rotatably mounted on the upper end of the vertical shaft 7 , and an anti-slip positioning component 10 is provided inside the U-shaped support frame 8 .

[0035] like Figure 2 As shown, the pipeline is first placed on the inner side of the U-shaped support frame 8 during transportation. For pipelines with larger diameters and longer lengths, two transport vehicles can be used to cooperate with each other for transportation. When the pipeline is placed on the inner side of the U-shaped support frame 8, the anti-slip positioning component 10 is used to position the pipeline to increase the stability of the pipeline placement and avoid shaking. At the same time, it can also be used for pipelines of different diameters. In addition, in the subsequent mobile transportation process, it can prevent the pipeline from sliding relative to the U-shaped support frame 8 due to shaking, thereby causing the pipeline to slip, ensuring that the pipeline is safely and stably placed on the inner side of the U-shaped support frame 8.

[0036] During transportation, workers only need to control the movement of the entire transport vehicle through the handle 6 and the push rod 5, and can adjust the height of the U-shaped support frame 8 through the lifting component 9 to meet the use requirements in a small space, making the pipeline transportation operation in a small space more convenient and quick; during transportation, the base 1 of the transport vehicle and the U-shaped support frame 8 can be controlled according to the surrounding environment. The rotation angle can be used to avoid obstacles more conveniently in a small space and smoothly complete the pipeline transportation operation.

[0037] Furthermore, an electric control assembly 11 is provided on the upper side of the base 1. The electric control assembly 11 is used to control the driving lifting assembly 9. The electric control assembly 11 includes a battery and a controller. The battery supplies power to the lifting assembly 9 and controls the driving lifting assembly 9 to operate.

[0038] Furthermore, the upper end of the vertical shaft 7 is rotatably mounted on the lower surface of the U-shaped support frame 8 through a bearing 71, and the lower end of the vertical shaft 7 slides and extends to the lower side of the sleeve 4 and is installed with a lifting seat 72; the U-shaped support frame 8 can be rotated relative to the upper end of the vertical shaft 7 and the base 1, and the height can be raised and lowered through the lifting component 9, so that it is suitable for using a transport vehicle in a narrow space.

[0039] The lifting assembly 9 includes two U-shaped vertical guide rails 91 fixed to the top surface of the base 1. The upper ends of the two U-shaped vertical guide rails 91 are fixed with an annular guide rail 93. A plurality of sliding brackets 94 are slidably provided in the annular guide rail 93. The upper ends of the sliding brackets 94 are jointly installed with double-sided gear rings 95.

[0040] The inner sides of the two U-shaped vertical guide rails 91 are both vertically rotatably installed with screw rods 92. The two sides of the lifting seat 72 extend into the two U-shaped vertical guide rails 91 respectively and are threadedly installed with the screw rods 92 on the same side. The upper ends of the two screw rods 92 extend to the upper side of the U-shaped vertical guide rails 91 and are respectively installed with driven gears 98. The lower end of the sleeve 4 is installed with a motor 96, which is electrically connected to the battery and the controller. The driving shaft of the motor 96 is installed with a driving gear 97. The driving gear 97 is engaged with the outer teeth of the bilateral gear rings 95, and the driven gear 98 is engaged with the inner teeth of the bilateral gear rings 95.

[0041] In the lifting assembly 9, the motor 96 is used to drive the driving gear 97 to rotate. Since the driving gear 97 is engaged with the outer teeth of the double-sided gear ring 95, and the driven gear 98 is engaged with the inner teeth of the double-sided gear ring 95, the motor 96 can control the two screw rods 92 to rotate simultaneously. Then, by using the threaded cooperation between the screw rod 92 and the lifting seat 72, the vertical shaft 7 and the U-shaped support frame 8 can be controlled to achieve height adjustment, thereby facilitating the transportation of pipelines in a narrow space.

[0042] Furthermore, the annular guide rail 93 includes two limit rings arranged in parallel above and below, and a slideway is formed between the two limit rings. The sliding bracket 94 has an L-shaped structure, and the lower end of the sliding bracket 94 is slidably set in the slideway between the limit rings, and the upper end is fixed on the lower surface of the bilateral gear ring 95.

[0043] Furthermore, there are multiple anti-slip positioning components 10, and the multiple anti-slip positioning components 10 are symmetrically arranged on both sides of the inner wall of the U-shaped support frame 8. The anti-slip positioning component 10 includes an anti-slip positioning rod 101 that is slidably installed with the inner wall of the U-shaped support frame 8, and the anti-slip positioning rod 101 is slidably installed with the inner wall of the U-shaped support frame 8 through a spring sliding shaft 102.

[0044] Furthermore, the anti-slip positioning rod 101 includes a horizontal section, an inclined section and a vertical section. The inclined section is fixed at the upper end of the vertical section, the horizontal section is fixed at the upper end of the inclined section, the end of the horizontal section away from the inclined section passes through the outer side of the U-shaped support frame 8, and the lower end of the vertical section passes through the outer side of the U-shaped support frame 8. The lower end of the U-shaped support frame 8 is provided with a sliding groove 103 that matches the lower end of the vertical section.

[0045] Furthermore, the spring slide shaft 102 comprises a slide shaft fixed in the middle of the vertical section. The end of the slide shaft, away from the vertical section, extends to the outside of the U-shaped support frame 8 and is fitted with a stop block. A spring is wound around the slide shaft and positioned between the inner sidewall of the U-shaped support frame 8 and the vertical section. The spring's elastic force ensures a stable clamping force when the anti-slip positioning rod 101 contacts the pipe, and can be used with pipes of different diameters.

[0046] Furthermore, a rubber sleeve is wrapped on the surface of the anti-slip positioning rod 101. The rubber sleeve provided on the anti-slip positioning rod 101 can increase the friction when in contact with the pipeline, thereby increasing the anti-slip effect on the pipeline.

[0047] When the pipeline is placed on the inner side of the U-shaped support frame 8, different clamping forces are formed between the pipeline and the anti-slip positioning component 10 according to the diameter of the pipeline. The clamping force can increase the stability and anti-slip effect of the pipeline after placement, thereby ensuring that the pipeline is stably supported on the U-shaped support frame 8 and transported stably during transportation, avoiding the pipeline from sliding off the U-shaped support frame 8 due to shaking or uneven force, ensuring the safety of the pipeline and personnel during transportation, and the operation process is simple and safe.
