Description

Technical Field

[0001] This invention relates to the field of water supply pipeline construction technology, and in particular to a device for transferring underground water supply pipelines. Background Technology

[0002] The underground water supply pipes of various sizes together form the water supply network, which is a major component of the urban water supply system and is closely related to people's daily lives. Before construction, the water supply pipes are transported to the construction site in advance. Before entering the site, they need to undergo strict inspection to ensure that the quality of the pipes is qualified before they can be unloaded and stacked on the construction site. During construction, the pipes are moved into the pre-excavated trench and assembled.

[0003] Before formal construction, a visual inspection of the pipes and fittings must be carried out again. Any pipes or fittings found to be defective must not be used. Qualified pipes are generally hoisted and placed into the trench over a short distance using flexible slings to complete the connection between pipes. Since qualified pipes are stored on the construction site, and the trench for construction is also located on the construction site, only short-distance transportation is required.

[0004] Currently, most pipelines can be lifted and placed into trenches over short distances using hoisting equipment. However, when encountering numerous surrounding obstacles, such as a pre-dug trench passing between two buildings where the distance between the buildings is less than the width of the hoisting equipment, the equipment cannot enter and thus cannot properly lift and place the pipelines into the trench. In such cases, the pipelines must be manually moved into the trench.

[0005] To address this issue, Chinese patent application number 201510545193.3 discloses a simple pipe transfer device. This device has an upper positioning plate and a lower positioning plate that can clamp the pipe for transportation without manual intervention. However, both inserting and removing the pipe between the upper and lower positioning plates require manual operation. For large-diameter pipes, multiple people are needed to move them, which is time-consuming and labor-intensive. Operations in confined spaces are difficult, and the pipe surface is easily damaged during transport, affecting its lifespan. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a device for transferring underground water supply pipelines, which can transport pipelines of different diameters, and can clamp and unload the pipelines without manual operation, thus preventing damage to the pipelines.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] This invention provides a device for transferring underground water supply pipelines, comprising at least two main components arranged one in front of the other, with adjacent main components connected by a connecting seat;

[0011] The main body is provided with two clamping plates with adjustable left and right spacing. The two clamping plates move closer or further apart to selectively clamp the underground water supply pipe. All the clamping plates of the main body form the clamping space of the underground water supply pipe.

[0012] The main body is also provided with an electromagnet facing the clamping space, which can help fix the underground water supply pipe.

[0013] The bottom of the main body is equipped with multiple electric wheels that can move in the front-to-back direction.

[0014] Optionally, the clamping plate is arc-shaped, and the two clamping plates are symmetrically arranged and protrude in a direction away from each other.

[0015] Optionally, the electromagnet is provided with an arc-shaped groove, which is used to fit the outer wall of the underground water supply pipe.

[0016] Optionally, the main body is provided with a bidirectional lead screw and a motor for driving the bidirectional lead screw to rotate. The clamping plate is screwed onto the bidirectional lead screw, and the rotation of the bidirectional lead screw can drive the two clamping plates to move towards or away from each other.

[0017] Optionally, the main body is a hollow cube, the bidirectional lead screw is disposed inside the main body, a limiting slot is provided on the side wall of the main body, a movable seat is screwed onto the bidirectional lead screw, one end of the clamping plate is connected to the movable seat, and the other end of the clamping plate protrudes from the main body through the limiting slot.

[0018] Optionally, an electric reversing wheel is provided below the connecting seat, and the traveling direction of the electric reversing wheel is perpendicular to the traveling direction of the electric traveling wheel;

[0019] When the electric traveling wheels are working, the electric reversing wheels are raised; when the electric reversing wheels are working, one set of electric traveling wheels cooperates with them to reverse direction and travel, while the other set of electric traveling wheels is raised.

[0020] Optionally, the main body is connected to the electric walking wheel via a first hydraulic cylinder;

[0021] The connecting seat is connected to the electric reversing wheel via a second hydraulic cylinder.

[0022] Optionally, the connecting seat is provided with a control box, which is electrically connected to the electric walking wheel, the electric reversing wheel, the motor, the first hydraulic cylinder, the second hydraulic cylinder and the electromagnet.

[0023] Optionally, the connecting seat includes a hollow sleeve and an insert plate that are respectively connected to two adjacent main body components. The hollow sleeve is fitted on the outside, and the insert plate can enter or extend into the hollow sleeve, thereby shortening or lengthening the distance between adjacent main body components.

[0024] Optionally, the insert plate is provided with several through holes, and the hollow sleeve is provided with a first bolt.

[0025] Secondly, this invention provides a method for using a device for transferring underground water supply pipelines. The device is moved above the underground water supply pipeline to be transferred using electric wheels. When a change of direction is needed, the electric wheels on one set of main components are raised, and the electric reversing wheel is lowered, causing the device to change direction. Then, the first hydraulic cylinder is activated, causing it to retract and lower both the first and second main components. During this descent, an electromagnet is energized, and after contacting the underground water supply pipeline, the pipeline is tightly attracted to the electromagnet. The first hydraulic cylinder is then activated again, causing both the first and second main components to rise until the underground water supply pipeline is detached from the ground. The motor is then activated, driving a bidirectional lead screw to rotate. Under the driving action of the screw thread, the bidirectional lead screw drives two sets of moving seats to move in opposite directions under the sliding limit action of the mounting block, thereby causing two sets of clamping plates to move in opposite directions, clamping and fixing the underground water supply pipeline. The underground water supply pipeline is then transferred using electric wheels. Once the preset position is reached, the first hydraulic cylinder is activated to lower the pipe until most of it enters the trench. At this point, the motor drives the bidirectional lead screw to reverse, causing the two sets of clamping plates to move towards each other, releasing the pipe. Then, the electromagnet is de-energized, and the pipe is fully inserted into the trench, completing the stable placement of the pipe.

[0026] (III) Beneficial Effects

[0027] The beneficial effects of this invention are as follows: This invention provides a device for transferring underground water supply pipes. By setting at least two main components, each capable of clamping the pipe, the stability of the clamping is improved. By incorporating clamping plates, the two clamping plates, when close together, can grip the sidewall of the pipe, achieving pipe gripping; when the two clamping plates move away from each other, the pipe falls, achieving automatic unloading. By incorporating an electromagnet, it can achieve magnetic attraction for most pipes. When the clamping plates are clamping, the electromagnet is energized to attract the pipe, assisting in clamping; when the clamping plates are removed, the electromagnet is de-energized, losing its magnetic attraction to the pipe, allowing the pipe to be smoothly unloaded. This device can transfer and transport pipes into trenches. It has a compact structure and small size, allowing free movement in complex environments with many obstacles. It effectively replaces manual labor for short-distance pipe transfer, saving time and effort, ensuring construction progress, and preventing damage to the pipe surface. Furthermore, the clamping position is adjustable, making it suitable for lifting and transferring water supply pipes of different lengths.

[0028] The clamping plate of the present invention is a symmetrically arranged arc shape, which is more suitable for the shape of the pipe. When used with an electromagnet with an arc groove, the clamping and fixing of the pipe is more secure.

[0029] This invention uses a motor to drive a bidirectional lead screw to rotate, which can cause the two clamping devices on both sides to move closer or further apart, and can automatically control the device to grip, clamp, and release the pipe.

[0030] The electric walking wheels of this invention can automatically travel in a straight line, and the electric reversing wheels can turn the device in the trench, adjust the direction of movement, and allow the pipeline to smoothly reach the designated location.

[0031] The connector of this invention allows adjustment of the distance between the two main components, making it suitable for pipes of different lengths. The connector's extended length is fixed by inserting bolts into the through holes, resulting in a more secure device.

[0032] This invention can control the electric walking wheel, electric reversing wheel, motor, first hydraulic cylinder, second hydraulic cylinder and electromagnet through a control box, thereby achieving automation. Attached Figure Description

Detailed Implementation

[0043] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0045] Example 1:

[0046] refer to Figures 1-8This invention protects a device for transferring underground water supply pipes, comprising at least two main body components 100 and 200 arranged one behind the other, connected to adjacent main body components 100 and 200 via connecting seats. Each main body component 100 and 200 is provided with two clamping plates 603 with adjustable lateral spacing. The two clamping plates 603 can be moved horizontally, allowing them to move closer or further apart to selectively clamp the underground water supply pipe. The clamping plates 603 of all main body components 100 and 200 form a clamping space for the underground water supply pipe. Each main body component 100 and 200 is also provided with an electromagnet 700 facing the clamping space, which assists in fixing the underground water supply pipe. The bottom of each main body component 100 and 200 is provided with multiple electrically driven wheels that can move in a front-to-back direction.

[0047] This invention improves clamping stability by using at least two main components, each capable of clamping the pipe. Clamping plates 603 are positioned close together to grip the pipe's side, enabling gripping; when the clamping plates move away, the pipe falls, allowing for automatic release. An electromagnet 700 provides magnetic attraction for most pipes. When the clamping plates 603 are clamping, the electromagnet 700 uses electromagnetic attraction to assist in clamping; when the clamping plates 603 are removed, the electromagnet 700 is de-energized, losing its magnetic attraction and allowing the pipe to be released smoothly.

[0048] refer to Figure 1 In one specific embodiment, the clamping plate 603 is arc-shaped, with two clamping plates 603 symmetrically arranged and protruding in a direction away from each other. The arc shape allows the clamping plate 603 to better fit against the outer wall surface of the pipe, improving the stability of the clamping.

[0049] refer to Figure 3 In one specific embodiment, the electromagnet 700 is provided with an arc-shaped groove, which can conform to the outer wall of the underground water supply pipe. The arc-shaped groove allows for a better fit to the outer wall of the pipe, making the pipe more stable when clamped; on the other hand, when the electromagnet 700 is energized, it can magnetically attract the pipe, assisting the clamping plate 603 in clamping the underground water supply pipe.

[0050] refer to Figure 4 In one specific embodiment, the main body 100, 200 is provided with a bidirectional lead screw 605 and a motor 600 for driving the bidirectional lead screw 605 to rotate. The clamping plate 603 is screwed onto the bidirectional lead screw 605. The rotation of the bidirectional lead screw can drive the two clamping plates to move towards or away from each other. The motor 600 may be a servo motor.

[0051] refer to Figures 1-3, in a specific embodiment, the main bodies 100, 200 are hollow cubic shapes. The bidirectional screw rod 605 is disposed inside the main bodies 100, 200. The side walls of the main bodies 100, 200 are provided with limiting slots 602. A moving seat 601 is screwed on the bidirectional screw rod 605. One end of the clamping plate 603 is connected to the moving seat 601, and the other end of the clamping plate 603 passes through the limiting slot 602 and protrudes from the main bodies 100, 200.

[0052] In a specific embodiment, an electric reversing wheel is provided below the connecting seat, and the traveling direction of the electric reversing wheel is perpendicular to the traveling direction of the electric traveling wheels; when the electric traveling wheels 501 are working, the electric reversing wheel 503 rises; when the electric reversing wheel 503 is working, one group of the electric traveling wheels 501 cooperates with it for reversing travel, and the other group of the electric traveling wheels 501 rises.

[0053] In a specific embodiment, the main bodies 100, 200 are connected to the electric traveling wheels 501 through the first hydraulic cylinders 500.

[0054] In a specific embodiment, the connecting seat is connected to the electric reversing wheel 503 through the second hydraulic cylinders 502.

[0055] In a specific embodiment, a control box 400 is provided on the connecting seat, and the control box 400 is electrically connected to the electric traveling wheels 501, the electric reversing wheel 503, the motor 600, the first hydraulic cylinders 500, the second hydraulic cylinders 502, and the electromagnets 700 respectively.

[0056] In a specific embodiment, the connecting seat includes a hollow sleeve 300 and a plug board 301 that are respectively connected to two adjacent main bodies 100, 200. The hollow sleeve 300 is sleeved outside, and the plug board 301 can enter or extend out of the hollow sleeve 300 to shorten or extend the distance between the adjacent main bodies 100, 200.

[0057] In a specific embodiment, several through holes 302 are provided on the plug board 301, and a first bolt 303 is provided on the hollow sleeve 300. The first bolt 303 can pass through the hollow sleeve and cooperate with the through holes 302.

[0058] The following are the specific embodiments.

[0059] As Figures 1 to 8 shown, in this embodiment, the number of main bodies is two, namely the first main body 100 and the second main body 200. The first main body 100 and the second main body 200 are two symmetrically arranged parts. Both the first main body 100 and the second main body 200 are hollow cuboids, and one end is open, which is convenient for disassembling, assembling, inspecting, and maintaining the components installed inside.

[0060] Refer Figure 2, Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , the connecting seat includes a hollow sleeve 300 and a plug board 301. The plug board 301 is fixedly connected to the first main body 100, and the hollow sleeve 300 is fixedly connected to the second main body 200. The plug board 301 is inserted into the hollow sleeve 300, and the hollow sleeve 300 and the plug board 301 are connected by a first bolt 303. The inside of the connecting seat is a hollow structure. The plug board 301 and the hollow sleeve 300 cooperate with each other. The plug board 301 can slide and expand telescopically inside the hollow sleeve 300, so as to adjust the effective length, enabling the distance between the first main body 100 and the second main body 200 to be adjusted flexibly.

[0061] Among them, when transferring a longer pipeline, adjusting the effective length of the hollow sleeve 300 and the plug board 301 to the maximum state can hold and transfer the longer pipeline more stably. When transferring a shorter pipeline, adjusting the effective length of the hollow sleeve 300 and the plug board 301 to the minimum state can ensure that the pipeline can be normally held.

[0062] Refer Figure 1 and Figure 2 As shown in Figure 1 and Figure 2 , the control box 400 is arranged on the connecting seat. The inside of the control box 400 includes electrical components such as a power supply and a frequency conversion controller. The control box 400 serves as a control center to control the normal operation and stop of each component, enabling each component to independently complete the functions it needs to perform.

[0063] Refer Figure 1 and Figure 3 As shown in Figure 1 and Figure 3 , first hydraulic cylinders 500 are respectively installed at the bottoms of the first main body 100 and the second main body 200, and electric traveling wheels 501 are installed at the bottoms of the first hydraulic cylinders 500. The first hydraulic cylinders 500 are controlled by a set of independent hydraulic control systems (not shown in the figure) and are responsible for controlling the flexible lifting of the first main body 100 and the second main body 200.

[0064] Refer Figure 1 and Figure 3 As shown in Figure 1 and Figure 3 , the bottom of the connecting seat is connected to an electric reversing wheel 503 through a second hydraulic cylinder 502, and the traveling direction of the electric reversing wheel 503 is perpendicular to the traveling direction of the electric traveling wheel 501. Both the electric traveling wheel 501 and the electric reversing wheel 503 are driven by independent motors. The electric traveling wheel 501 is used for traveling, and the electric reversing wheel 503 is used for steering.

[0065] Specifically, refer Figure 4 and Figure 8As shown, when walking, the electric driving wheel 501 contacts the ground, and the electric reversing wheel 503 is in a suspended state, ensuring unidirectional walking. When steering is required, the second hydraulic cylinder 502 pushes the electric reversing wheel 503 down to make it contact the ground, and then the electric driving wheel 501 under the first main body 100 rises off the ground. At this time, the steering function can be achieved by the rotation of the electric reversing wheel 503.

[0066] In this embodiment, the electric driving wheel 501 and the electric reversing wheel 503 can be replaced by a walking mechanism for manually controlling the direction, which consists of two groups of universal wheels, two groups of electric wheels and a handrail. Here, the two groups of electric wheels are installed at the bottom end of the first hydraulic cylinder 500 under the first main body 100, the two groups of universal wheels are installed at the bottom end of the first hydraulic cylinder 500 under the second main body 200, and the handrail is installed on the second main body 200. During actual operation, automatic walking is achieved through the two groups of electric wheels, and the construction personnel can control the universal wheels for steering through the handrail, and can also achieve the automatic walking and steering of the transfer device.

[0067] Refer to Figure 4 、 Figure 5 and Figure 8 As shown, motors 600 are respectively installed on one side of the first main body 100 and the second main body 200. The specific model of the motor 600 can be GM7G-09AFC61S. Ball bearings are respectively fixedly connected to both sides inside the first main body 100 and the second main body 200. A bidirectional screw rod 605 is installed between the two groups of ball bearings. The rotor shaft of the motor 600 is fixedly connected to one side of the bidirectional screw rod 605 through a coupling.

[0068] Refer to Figure 4 、 Figure 5 and Figure 8 As shown, two groups of moving seats 601 are installed outside the bidirectional screw rod 605, and a clamping plate 603 is installed below the moving seat 601. The two groups of moving seats 601 are symmetrically arranged about the center of the bidirectional screw rod 605, and threaded holes matching the threads of the bidirectional screw rod 605 are provided on the horizontal center line of the moving seat 601. When the bidirectional screw rod 605 rotates, under the driving action of the threads, the two groups of moving seats 601 can move horizontally away from or towards each other at the same time, so that the clamping plates 603 below the two groups of moving seats 601 are loosened and clamped.

[0069] Refer to Figure 1 and Figure 3As shown, the electromagnets 700 are respectively fixedly connected to the bottom ends of the first main body 100 and the second main body 200, and the buffer pads 701 are fixedly connected to the bottom ends of the electromagnets 700. The buffer pads 701 can play a good buffering and protective effect when the electromagnets 700 adsorb the pipeline, preventing the pipeline from colliding with the electromagnets 700 and causing surface damage, which is beneficial to extending the service life of the pipeline.

[0070] Among them, the electromagnets 700 are electrically connected to wires for power on and off (not shown in the figure). When powered on, the electromagnets 700 have strong magnetism and can adsorb and fix the side wall of the pipeline. When the pipeline needs to be lowered, the power supply is disconnected, and the magnetism of the electromagnets 700 disappears, enabling the pipeline to be smoothly lowered.

[0071] See Figure 2 and Figure 6 As shown, there are two groups of the first bolts 303 penetrating through the hollow sleeve 300, and there are two rows of through holes 302 provided on the plug board 301, with multiple groups evenly arranged in each row. The first bolts 303 are matched with the through holes 302. After the first bolts 303 penetrate through the inside of the through holes 302 and are locked, the plug board 301 can be locked inside the hollow sleeve 300. The opening of multiple groups of through holes 302 enables the plug board 301 to be locked after adjusting the length inserted into the hollow sleeve 300.

[0072] See Figures 1-3 As shown, two groups of the second hydraulic cylinders 502 are respectively fixedly connected to both sides of the connecting seat, and the electric reversing wheels 503 are fixedly installed at the bottom ends of the second hydraulic cylinders 502. The specific models of the second hydraulic cylinders 502 and the first hydraulic cylinder 500 can both be 3TG - E86*350. The second hydraulic cylinders 502 are used to drive the electric reversing wheels 503 to lift and lower.

[0073] Among them, the installation positions of the second hydraulic cylinders 502 and the electric reversing wheels 503 on the connecting seat should be as close as possible to the first main body 100 to ensure that when the electric walking wheels 501 are lifted, the overall device still has a stable four - corner support structure, avoiding tilting and toppling during the turning process.

[0074] See Figures 4-7 As shown, an installation block 604 is fixedly connected to the bottom end of the moving seat 601, and the clamping plate 603 is fixedly installed at the bottom end of the installation block 604. Two groups of limiting slots 602 are opened on the lower end surfaces of the first main body 100 and the second main body 200, and the installation block 604 slides through the inside of the limiting slots 602.

[0075] Among them, when the bidirectional screw rod 605 drives the moving seat 601 to move horizontally, the installation block 604 slides inside the limit slot 602, which can play a role in limiting and guiding the horizontal movement of the moving seat 601, enabling the moving seat 601 to move horizontally smoothly and not deflect following the bidirectional screw rod 605 under the action of the friction force between the threads, ensuring that the two clamping plates 603 can clamp more smoothly.

[0076] As shown Figure 7 in the figure, a fixing groove 606 is opened on the lower end surface of the installation block 604, and two sets of assembly holes 607 are opened at a position near the top end of the clamping plate 603. The top end of the clamping plate 603 is inserted into the fixing groove 606. The plug-in installation between the clamping plate 603 and the fixing groove 606 has a pre-positioning effect, making the assembly of the clamping plate 603 more accurate.

[0077] As shown Figure 7 in the figure, two sets of second bolts 608 penetrate between the two sides of the fixing groove 606, and the second bolts 608 are matched with the assembly holes 607. After the clamping plate 603 is inserted into the fixing groove 606, by passing the second bolts 608 through the assembly holes 607 and locking them, the part of the clamping plate 603 inserted into the fixing groove 606 can be fixed, thereby fixing the clamping plate 603 to the bottom end of the installation block 604.

[0078] Among them, the clamping plate 603 is an arc-shaped plate with a certain curvature, and the surface is smooth enough not to cause damage to the surface of the pipeline when clamping. And the clamping plate 603 can have various specifications, and the curvature of each specification is different. By replacing the clamping plate 603, pipelines of various specifications can be clamped. When it is necessary to replace the clamping plate 603 of different specifications, only need to remove the second bolts 608, and the clamping plate 603 can be removed, which is convenient to replace the clamping plate 603 matching the pipeline to be fixed according to the pipeline.

[0079] As shown Figure 3 and Figure 4 in the figure, the lower end surface of the electromagnet 700 is arc-shaped, and the curvature of the arc is large enough to adapt to the adsorption and fixation of pipelines of various calibers.

[0080] As shown Figures 3-5 in the figure, the buffer pad 701 can be one of a polyurethane buffer pad, an ethylene propylene diene monomer rubber elastic buffer pad, an EVA elastic foam buffer pad or an industrial rubber buffer pad. In this embodiment, in order to meet the good buffer effect on the pipeline, the main material of the buffer pad 701 is a polyurethane buffer pad with a certain structural strength and compressive performance.

[0081] As shown Figure 2 and Figure 7As shown, before use, adjust the distance between the first main body 100 and the second main body 200 according to the length of the pipeline to be transferred, and complete the fixation using the first bolt 303. Then, replace and install the holding plate 603 with the corresponding shape.

[0082] Refer Figure 1 and Figure 8 As shown, during use, move the transfer device above the pipeline to be transported and transferred through the electric driving wheels 501. Then, start the first hydraulic cylinder 500 to contract it. At this time, both the first main body 100 and the second main body 200 descend. During the descending process, power on the electromagnet 700. After the electromagnet 700 contacts the pipeline, it will tightly adsorb to it. At this time, start the first hydraulic cylinder 500 again to make both the first main body 100 and the second main body 200 rise a certain distance until the pipeline is lifted off the ground. Then, start the motor 600. The motor 600 will drive the bidirectional screw rod 605 to rotate. Under the driving effect of the thread, the bidirectional screw rod 605 will drive the two groups of moving seats 601 to move towards each other under the sliding limit of the mounting block 604, so that the two groups of holding plates 603 move towards each other to tightly hold and fix the pipeline.

[0083] Refer Figure 1 and Figure 8 As shown, afterwards, the transfer device transfers the tightly held and fixed pipeline for a short distance through the electric driving wheels 501, making the pipeline located above the pre-dug trench. Then, start the first hydraulic cylinder 500 to lower the pipeline until most of the pipeline enters the trench. At this time, drive the bidirectional screw rod 605 to reverse through the motor 600, making the two groups of holding plates 603 move towards each other to loosen the pipeline. Then, cut off the power supply of the electromagnet 700 to make it lose the adsorption and fixation effect on the pipeline. At this time, the pipeline is completely released and will directly enter the trench to complete the stable placement of the pipeline.
