Description

Technical Field

[0001] This utility model relates to the field of pipe gallery construction technology, specifically to a pipe jacking and transportation device for pipe gallery construction. Background Technology

[0002] Underground utility tunnels, as an important means of intensive laying of municipal infrastructure, can centrally lay municipal pipelines such as electricity, communications, radio and television, water supply and drainage, heating, and gas. They are of great practical significance for alleviating the pressure of urban network operation and maintenance, reducing economic losses caused by the use of above-ground pipelines, fully developing and utilizing underground space, and building modern cities.

[0003] During the construction of integrated utility tunnels, due to the large excavation cross-section and deep excavation, especially when located on or passing through existing roads, pipe jacking is often used to avoid the impact of excavation on the environment and traffic, and for the sake of project safety. In particular, for areas with abundant groundwater such as deep silt or silty soft soil or sandy or gravelly layers, the implementation effect of the pipe jacking working well is crucial.

[0004] Pipe jacking, a trenchless construction technique, is a method of tunneling or underground pipelines that crosses various obstacles such as towers, roads, rivers, or buildings. During pipe jacking, a prepared jacking pit or shaft is used as the starting point. The pipe rack is lowered into the pit, and hydraulic jacks are used to press it into the soil. Simultaneously, the soil in front of the pipe rack is excavated and removed.

[0005] During construction, the limited space at the construction site and the confined transportation space make it inconvenient to use existing transport vehicles for transshipment. Although precautions are taken at all times during transportation, collisions and crushing accidents still need to be considered, resulting in poor safety. Therefore, in the confined space of the pipe gallery construction site, manual handling is still relied upon, which makes the transportation process quite inconvenient, especially for the transportation of large-diameter water supply steel pipes, which are heavy, bulky, time-consuming, and labor-intensive, seriously reducing work efficiency.

[0006] Therefore, it is necessary to study a pipe jacking transportation device for pipe gallery construction. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a pipe jacking transportation device for pipe gallery construction, which can effectively solve the problems of inconvenient use of transportation vehicles and time-consuming and labor-intensive manual handling when transporting pipes in limited construction sites.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A pipe jacking transportation device for pipe gallery construction includes at least two sets of transportation vehicles used together.

[0010] The transport vehicle includes a support base, a pipe jacking bracket, a transport handle, and a set of transport wheels.

[0011] The support base has a semi-enclosed structure with an opening at the top, and transport handles are fixedly connected to both the left and right sides of the support base.

[0012] The jacking pipe bracket is fixedly installed in the support base. The jacking pipe bracket has a semi-circular support groove with an upper opening that matches the size of the jacking pipe. A bottom support plate is fixedly installed on the support groove to support the jacking pipe.

[0013] The transport wheel set is arranged in two sets on the bottom left and right sides of the support base. The transport wheel set is fixedly connected to the support base through a rotating support to facilitate turning.

[0014] Furthermore, a side rib plate is fixedly connected between the lower surface of the handle and the support base, and the side rib plate is a trapezoid that is wider at the top and narrower at the bottom.

[0015] Furthermore, an auxiliary wheel seat is fixedly connected to the bottom of the side rib plate. The auxiliary wheel seat is a U-shaped structure with an opening at the bottom. An auxiliary wheel is rotatably arranged in the auxiliary wheel seat, and the auxiliary wheel is located above the transport wheel assembly and is spaced from the ground.

[0016] Furthermore, the diameter of the auxiliary wheel gradually narrows from both sides towards the center, forming a spindle-shaped structure that is thicker at both ends and thinner in the middle.

[0017] Furthermore, several ribs are fixedly connected between the top surface of the auxiliary wheel seat and the side wall of the side rib plate.

[0018] Furthermore, the side wall of the jacking bracket and the lower surface of the bottom support plate are fixedly connected at intervals with several reinforcing ribs.

[0019] Furthermore, the transport wheel assembly includes a transport wheel seat and a transport wheel, wherein the transport wheel seat has a bottom-opening structure, and the transport wheel is rotatably mounted in the transport wheel seat.

[0020] Furthermore, the transport wheel is a columnar structure extending in the left-right direction, and multiple transport wheels are spaced apart in the front-back direction.

[0021] The beneficial effects of the above technical solution are:

[0022] This invention employs at least two sets of transport vehicles working together to effectively distribute the weight of the jacking pipe, reduce ground pressure at single points, and lower the risk of settlement caused by uneven foundations and concentrated loads. The transport vehicles form a stable support structure through a semi-enclosed support base with an upper opening and a built-in jacking pipe bracket. The jacking pipe bracket has an upper-opening semi-circular groove adapted to the size of the jacking pipe, on which a bottom support plate is fixedly installed. The jacking pipe can be stably supported in the groove, and with the bottom support plate, the force is evenly distributed, preventing the pipe from rolling, shaking, or shifting during transportation, thus ensuring the stability and safety of the transportation process.

[0023] In addition, by setting transport wheel sets on the left and right sides of the bottom of the support base and connecting them with the support base using rotating supports, the transport vehicle has good steering ability, adapting to the transportation needs of complex and narrow paths in the pipe gallery. With the transport handle, it is easy to push or adjust the direction manually, which significantly reduces the labor intensity of the operators.

[0024] This utility model has a compact overall structure and is suitable for typical scenarios such as limited space, tortuous passages, and no mechanical access in pipe jacking construction. It can effectively solve the problems of inconvenient use of transport vehicles and time-consuming and labor-intensive manual handling when transporting pipes in limited construction sites. It can be effectively applied to the transportation of large-diameter pipes in limited construction sites and improve the portability of pipe jacking transportation. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0032] This embodiment aims to provide a pipe jacking transportation device for pipe gallery construction, which is mainly used for transporting jacked pipes during pipe gallery construction. It addresses the problems of inconvenient use of transport vehicles and time-consuming and labor-intensive manual handling when transporting pipes in limited construction sites.

[0033] A pipe jacking and transport device for pipe gallery construction, such as Figure 5 This includes at least two sets of transport vehicles used in a set. For example... Figure 1 and Figure 2 The transport vehicle 1 includes a support base 2, a pipe jacking bracket 3, a transport handle 4, and a transport wheel set 5.

[0034] The support base 2 is a semi-enclosed structure with an opening at the top, made of three steel plates welded together. Transport handles 4 are welded and fixedly connected to both the left and right sides of the support base 2 for hand-held pushing of the transport vehicle 1.

[0035] The pipe jacking bracket 3 is welded and fixed in the support base 2. The pipe jacking bracket 3 is made of steel plate and is vertically welded in the support base 2. The pipe jacking bracket 3 has a semi-circular support groove with an upper opening that matches the size of the pipe jacking 13. A bottom support plate 6 is welded and fixed on the groove to support the pipe jacking 13, prevent stress concentration, and ensure that the pipe jacking 13 is evenly stressed. Several reinforcing ribs 12 are fixedly connected at intervals between the side wall of the pipe jacking bracket 3 and the lower surface of the bottom support plate 6 to avoid stress concentration at the connection node between the pipe jacking bracket 3 and the bottom support plate 6 and improve the firmness of the bottom support plate 6.

[0036] Two sets of transport wheel sets 5 are arranged on the left and right sides at the bottom of the support base 2. The transport wheel sets 5 are fixedly connected to the support base 2 via rotating supports 7 to facilitate steering. Specifically, as shown... Figure 4 The transport wheel assembly 5 includes a transport wheel base 501 and transport wheels 502. The transport wheel base 501 has a structure with openings at the front and rear and a bottom opening. The transport wheels 502 are rotatably mounted in the transport wheel base 501 via a rotating shaft. The transport wheels 502 are columnar structures extending in the left-right direction. Multiple transport wheels 502 are spaced apart in the front-back direction to reduce pressure damage to the ground.

[0037] Furthermore, a side rib plate 8 is fixedly connected between the lower surface of the handle and the support base 2. The side rib plate 8 is a trapezoid with a wider top and a narrower bottom. On the one hand, it can improve the strength of the structure. On the other hand, when the transport wheel 502 is stuck in the ground depression and cannot move forward, it can be pried with a crowbar using the bottom of the side rib plate 8 as the fulcrum, thus solving the problem that the small transport wheel 502 is prone to getting stuck in the ground depression and getting stuck.

[0038] Furthermore, an auxiliary wheel seat 9 is fixedly connected to the bottom of the side rib plate 8. The auxiliary wheel seat 9 is a U-shaped structure with an opening at the bottom. An auxiliary wheel 10 is rotatably mounted in the auxiliary wheel seat 9. The auxiliary wheel 10 is located above the transport wheel set 5 and is spaced from the ground. The auxiliary wheel 10 is mainly used for prying with a crowbar. Using the wheel surface of the auxiliary wheel 10 as a fulcrum, compared to using the side rib plate 8 as a fulcrum directly, can reduce friction damage and facilitate the transport vehicle 1 to move forward and get out of the jamming point.

[0039] Furthermore, such as Figure 3 The diameter of the auxiliary wheel 10 gradually narrows from both sides towards the center, forming a spindle-shaped structure that is thick at both ends and thin in the middle. This structure can limit the pry bar to the left and right, prevent slippage and misalignment, and make it easier to pry.

[0040] Furthermore, several ribs 11 are fixedly connected between the top surface of the auxiliary wheel seat 9 and the side wall of the side rib plate 8, making the structure of the auxiliary wheel seat 9 more stable, avoiding stress concentration, and reducing the risk of breakage of the connection node between the auxiliary wheel seat 9 and the side rib plate 8 when prying.
