Description

Technical Field

[0001] The present invention relates to the technical field of pipe jacking transportation, and in particular to transportation equipment and a transportation method for a pipe jacking water delivery pipe section. Background Art

[0002] Pipe jacking is a pipeline burial construction technique that requires minimal or no excavation. Within a working pit, the jacking force generated by jacking equipment overcomes the friction between the pipe and the surrounding soil, allowing the water pipe to be pushed into the soil according to the designed slope. Pipe jacking sections are typically cast in a prefabrication plant, then transported to the construction site by a transport vehicle. Finally, a hoisting crane is used to lift the sections into the construction pit.

[0003] Prior art typically uses a hanging crane with a cable equipped with two hooks. Holes are drilled in the pipe segment to install lifting lugs, which are then hooked onto the lugs to lift the segment. Alternatively, the segment is tied to a rope, which is then hooked onto the hook. However, installing the lifting lugs requires drilling holes in the segment, which can affect the overall strength of the segment. Binding the segment and removing the ropes are time-consuming, which can affect the progress of the pipe jacking operation.

[0004] Therefore, the existing technology needs to be improved. Summary of the Invention

DETAILED DESCRIPTION

[0030] In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention. The following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] It should be noted that similar numbers and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in the subsequent figures. In the description of the embodiment of the present invention, "plurality" represents at least 2. In the description of the embodiment of the present invention, it should also be noted that, unless otherwise clearly stipulated and limited, the terms "setting", "installation", "connection", 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 it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] Example 1, please refer to Figures 1 to 4 , shown is a transportation device for a jacking water pipe section according to Example 1 of the present invention, and the specific structure and principle are described as follows.

[0033] Combine Figure 1As shown, the automatically delivered transport frame for pipe construction in this embodiment mainly includes three parts: a jacking track 1, a lifting transport frame 2 and an inclined rolling track 3. The inclined rolling track 3 is used to guide the pipe section 9 to roll toward the lifting transport frame 2. The lifting transport frame 2 transports the pipe section 9 to the jacking track 1. The jacking track 1 is used as a track for the pipe section 9 to move forward.

[0034] In some implementations of this embodiment, Figure 1 and Figure 4 As shown, two sets of inclined rolling tracks 3 are installed, fixed to the left and right sides of the top of the construction pit. These tracks consist of a slideway 301, a baffle 302, and a clamping plate 303. The slideway 301 is a tilted flat plate, on which the pipe section 9 rests. The triangular bracket 304 is a metal pipe column secured to the ground with ground spikes, bolts, and other tools. This support ensures that the end of the slideway 301 closer to the construction pit is lower than the end farther away, facilitating the rolling of the pipe section 9 toward the construction pit.

[0035] It should be noted that the inclination angle of the slideway 301 does not exceed 10°, and in this embodiment it is preferably 8° or 10° to ensure that the pipe segment 9 rolls slowly.

[0036] Further, combined Figure 4 As shown, baffles 302 are fixedly installed on both sides of the slide 301 to limit the two ends of the pipe section 9. Two clamps 303 are installed at the end of the slide 301 close to the construction well. The clamps 303 are inserted into the grooves of the baffles 302. The clamps 303 are perpendicular to the surface of the slide 301 to prevent the pipe section 9 from rolling. And only one pipe section 9 can be accommodated between the two clamps 303. When the pipe section 9 needs to be released, the clamp 303 on the left is removed first. After the pipe section 9 is moved away, the clamp 303 on the left is installed and the clamp 303 on the right is removed. After the remaining pipe section 9 is moved, the clamp 303 on the right is installed.

[0037] In some implementations of this embodiment, Figure 1 and Figure 2 As shown, the lifting and transporting frame 2 mainly comprises a lifting frame 201, a first load plate 204, and a second load plate 205. The lifting frame 201 adopts a gantry frame as is conventionally used. An electric hoist is mounted on the gantry frame. The electric hoist is connected to a first sling 202 and a second sling 203 that can be extended into the construction well. The first sling 202 has two or more slings and is located on the left side, while the second sling 203 has two or more slings and is located on the right side. The lower end of the first sling 202 is connected to the lifting lug at the top of the first load plate 204, and the lower end of the second sling 203 is connected to the lifting lug at the top of the second load plate 205. The electric hoist controls the synchronous retraction and extension of the first sling 202 and the second load plate 203, thereby controlling the raising and lowering of the first load plate 204 and the second load plate 205.

[0038] Further, combined Figure 1 、 Figure 2 and Figure 3 As shown, in order to guide the rise and fall of the bearing plate 1 204 and the bearing plate 2 205, four guide rods 6 are vertically installed in the construction well. A guide plate 7 is hinged on the left side of the bearing plate 1 204, and a guide plate 7 is also hinged on the right side of the bearing plate 205. Figure 3 As shown, two upper and lower guide holes 701 are provided on the left and right guide plates 7, and the guide rod 6 passes through the guide holes 701. Through the cooperation of the guide rod 6 and the guide holes 701, it is ensured that the supporting plate 1 204 and the supporting plate 2 205 rise or fall stably, reducing the horizontal shaking.

[0039] It should be noted that guide sleeves 702 are fixedly mounted on the top and bottom surfaces of the guide plate 7 . The inner diameter of the guide sleeve 702 is consistent with the guide hole 701 and they are concentrically aligned. The guide sleeve 702 makes the guide plate 7 more stable.

[0040] In some implementations of this embodiment, Figure 3 As shown, a winch 1 (4) is fixedly mounted on the lower side of the first carrier plate 204 near the second carrier plate 205, with a retractable cable 1 (401) wound around its drum. A winch 2 (5) is fixedly mounted on the upper side of the second carrier plate 205 near the first carrier plate 204, with a retractable cable 2 (501) wound around its drum.

[0041] Further, combined Figure 1 and Figure 3 As shown, a mounting groove 1 2041 is defined on the upper side of the first carrier plate 204, near the side wall of the second carrier plate 205. The first vertical pulley 2042 is fixed in the mounting groove 1 2041. The second cable 501 passes through the wheel groove of the first vertical pulley 2042 and is then fixedly connected to the second carrier plate 205. Similarly, a mounting groove 2051 is defined on the lower side of the second carrier plate 205, near the side wall of the first carrier plate 204. The second vertical pulley 2052 is fixed in the mounting groove 2051. The first cable 401 passes through the wheel groove of the second vertical pulley 2052 and is then fixedly connected to the first carrier plate 204.

[0042] It should be noted that the vertical pulley 1 2042 and the vertical pulley 2 2052 serve as movable pulleys, making it easier to reel in the cable 1 401 and the cable 2 501 .

[0043] The winch 1 4, winch 2 5, vertical pulley 1 2042, and vertical pulley 2 2052 are centrally symmetrical, and the winch 1 4 and winch 2 5 control the synchronous retraction and extension of the cable 1 401 and the cable 2 501, thereby controlling the width of the slot 206 between the bearing plate 1 204 and the bearing plate 2 205. Figure 1As shown in FIG1 , after the first and second cables 401 and 501 are tightened, the width of the slot 206 becomes smaller, making it easier to lift the pipe section 9. Figure 2 As shown, after the first and second cables 401 and 501 are released, the width of the clamping slot 206 becomes larger, making it easier to remove the pipe section 9.

[0044] It should be noted that, in order to prevent the edges and corners of the bearing plate 1 204 and the bearing plate 2 205 from causing a large pressure on the pipe section 9, as shown in FIG. Figure 3 As shown, the right side of the support plate 1 204 and the left side of the support plate 2 205 are wrapped with a rubber pad 8. The rubber pad 8 has elasticity and can be deformed after being compressed, which has a good protective effect on the pipe section 9.

[0045] In some implementations of this embodiment, the jacking track 1 is installed in the construction well. The jacking track 1 has a guide rail 101 aligned with the excavation direction. The jacking track 1 is used to support the pipe segment 9 to facilitate the hydraulic press on the rear side to push the pipe segment 9 into the hole for jacking construction.

[0046] Further, combined Figure 1 As shown, the jacking track 1 is provided with a support frame 102 to increase the strength of the jacking track 1. A plurality of sleepers 103 are installed at the bottom of the support frame 102 to increase the contact area and prevent the jacking track 1 from sinking.

[0047] Example 2: This example provides a transportation method, which uses the transportation equipment for the jacking pipe water supply pipe section of Example 1 to transport the pipe section 9 outside the construction well to the jacking track 1 inside the construction well.

[0048] Before transportation, the pipe segments 9 for construction are temporarily placed on the inclined rolling track 3. Hoists 1 4 and 2 5 tighten cables 1 401 and 2 501, bringing load plates 1 204 and 2 205 closer together and closing the gaps 206. Slings 1 202 and 203 then lift load plates 1 204 and 205 until they are aligned with the inclined rolling track 3. During transportation, one pipe segment 9 rolls down the slide 301 to the gap 206, and then slings 1 202 and 203 lower load plates 1 204 and 205. When approaching the jacking track 1, winches 1 4 and 2 5 release cables 1 401 and 2 501 to a certain length, causing load plates 1 204 and 205 to move away from each other and the slit 206 to open. The bottom of pipe segment 9 is now exposed through the slit 206, allowing load plates 1 204 and 205 to continue descending and lift the pipe segment 9 onto the jacking track 1. After lifting, winches 1 4 and 2 5 release cables 1 401 and 2 501 to their maximum length, causing load plates 1 204 and 205 to move away from each other and the slit 206 to open to its maximum width. At this point, the width of the slit 206 is greater than the width of the pipe segment 9. Slings 1 202 and 203 lift load plates 1 204 and 205, separating them from the pipe segment 9. This completes the transport of the pipe segment 9. During the transportation of the pipe segment 9, no lifting lugs are required, so the strength of the pipe segment 9 is higher, and no rope binding is required, so the efficiency of the pipe jacking construction is higher.

[0049] In summary, the present invention provides a transportation device for a jacking pipe water supply section, which includes a jacking track 1, a lifting transport frame 2 and an inclined rolling track 3. The jacking track 1 is arranged in a construction well, and the jacking track 1 has a guide rail 101 aligned with the excavation direction.
