Abstract

The invention provides a road crossing sleeve penetrating leading-in vehicle for a buried pipeline. The road crossing sleeve penetrating leading-in vehicle for the buried pipeline comprises three arc-shaped supporting plates, wherein a roller shaft is arranged at each of the front part and the rear part of each arc-shaped supporting plate; the diameter of the roller body of each roller shaft is 50mm, shaft ends are arranged on the two sides of each roller shaft, the shaft ends are arranged in ear plates, and the ear plates are fixedly connected with the outer sides of the arc surfaces of thearc-shaped supporting plates; the two sides of the arc-shaped supporting plates are fixedly connected to with shaft pipes, the side edges of the three arc-shaped supporting plates are sequentially connected with the side edges to form a large arc plate, the shaft pipes of each two adjacent arc-shaped supporting plates are arranged in a staggered mode, and pins are arranged in the shaft pipes in apenetrating mode; and the road crossing sleeve penetrating leading-in vehicle for the buried pipeline is further provided with L-shaped steel plate hooks, the lower ends of the L-shaped steel plate hooks are fixedly connected with the front end parts of the arc-shaped supporting plates, bolt holes are formed in the upper end parts of the L-shaped steel plate hooks, and nuts are arranged in the bolt holes. The invention further provides a using method of the above road crossing sleeve penetrating leading-in vehicle for the buried pipeline. The using method specifically comprises the following steps that the above leading-in vehicle is clamped and sleeved on the head end of a main pipe, and then the tail end of the main pipe is lifted, so that the main pipe is parallel with a sleeve, and themain pipe is advanced in the state that the main pipe is kept parallel with the sleeve. The scheme prevents anticorrosive coating at the surface of the main pipe from being damaged.

Example Embodiment

[0021] The present invention will be described in detail below with reference to the drawings and embodiments:

[0022] Such as Figure 1-5 The shown is an underground pipeline crossing casing pipe introduction vehicle, which includes three arc-shaped pallets 1, and each arc-shaped pallet 1 is provided with a roller 3 at the front and the rear of the plate. The diameter of the body is 50mm, and the shaft ends are arranged on both sides. The shaft ends are installed in the lug plate 2. The lug plate 2 is fixedly connected to the outer side of the arc surface of the arc-shaped support plate 1; the two sides of the arc-shaped support plate 1 are fixed to the shaft tube 4, The sides of the three arc-shaped pallets 1 are connected in turn to form a large arc plate. The shaft tubes 4 of the two adjacent arc-shaped pallets 1 are staggered, and the shaft tube 4 is provided with a pin 5; The lower end of the L-shaped steel plate hook 6 is fixed to the front end of the arc-shaped pallet 1, and the upper end of the L-shaped steel plate hook 6 is provided with a bolt hole, and a bolt 7 is installed in the bolt hole.

[0023] The roller shaft 3 of the present invention is made of φ50mm round steel, there are 6 roller shafts, and 2 are installed at the bottom of each arc-shaped pallet, such as figure 1 The roller shaft shown is equipped with shaft ends at both ends of the roller body. The shaft ends can be milled on the basis of φ50mm round steel, or small diameter round steel welded at the center of the two ends of the roller body.

[0024] The arc-shaped pallet 1 of the present invention is formed by pressing a steel plate with a thickness of 10 mm and a size of 200*500 mm. The arc of the arc-shaped pallet of this practical embodiment is set to R=600mm. The bottom of the arc pallet (outside the arc) is fixedly connected to the ear plate 2. In this embodiment, the lug plate is made of 10mm steel plate, the size of the steel plate is 70*55mm; the lug plate has a φ22 round hole for installing the roller shaft end. A total of 12 ear plates are required.

[0025] The L-shaped steel plate hook 6 of the present invention is used to fix the tool on the end of the main pipe 8. The height of the L-shaped steel plate hook 6 is greater than the wall thickness of the main pipe 8, and the M20 bolt provided at the upper end of the L-shaped steel plate hook is used to press the pipe through.

[0026] Use the above-mentioned buried pipeline crossing casing pipe piercing tool for pipe piercing construction, combined Image 6 , The specific steps are as follows:

[0027] First, fix the shaft tube 4 on both sides of the arc-shaped pallet 1, and select 2-3 arc-shaped pallets according to the pipeline size of the buried main pipe 8 and assemble them in parallel to form an introduction vehicle. The shaft tubes of the adjacent arc-shaped pallets 1 are staggered Setting, adopting the pin shaft 5 to insert the shaft tube 4 to connect the arc-shaped plates. Such as image 3 Shown.

[0028] In the second step, set the L-shaped steel plate hook 6 of the lead-in vehicle to the head end of the underground pipe main pipe 8, and tighten the bolt 7 to fix the lead-in vehicle to the bottom of the pipeline.

[0029] In the third step, after the head end of the main pipe is fed into the casing 9, use a forklift to lift the tail end of the main pipe 8 so that it is parallel to the inner wall of the casing 9 and push forward until it passes through the casing 9.

[0030] The fourth step is to construct from the other end of the casing 9 and remove the lead-in truck for subsequent use.

[0031] In this construction method, the main pipe and the casing are in a horizontal state, and the main pipe will not contact the inner wall of the casing during the advancing movement. Therefore, the anti-corrosion layer is prevented from contacting the inner wall of the casing and the degree of damage is greatly reduced. At the same time, the efficiency of pipe penetration is increased to reduce the construction cost, and the three parts are connected by pin shafts, which can be used for various specifications of casing.
