[0029] like Figures 1 to 8 As shown, the working pipe conveying device for pipe jacking construction includes a top fastener 51 and a bottom fastener 52. The top fastener 51 and the bottom fastener 52 are interlocked and sleeved on the working pipe 4. The two ends of the top fastener 51 and the two ends of the bottom fastener 52 are connected by a connecting component. A sliding component 1 55, a sliding component 2 54 and an elastic telescopic member are arranged at the bottom of the bottom fastener 52. The sliding component 1 55 is arranged at the center of the bottom wall of the bottom fastener 52 through the elastic telescopic member, and a group of sliding components 2 54 are respectively arranged on both sides of the sliding component 1 55.

[0030] In this embodiment, two groups of elastic telescopic parts are provided, each group includes a bottom plate 563, a sleeve 564 and a spring 565, the bottom plate 563 is provided on the bottom wall of the bottom fastener 52, the sleeve 564 and the spring 565 are provided on the bottom plate 563, the two sleeves 564 of the two groups of elastic telescopic parts are close to each other on one side along the axis direction of the sleeve 564, the spring 565 is provided in the sleeve 564, the ends of the two springs 565 away from the bottom plate 563 are respectively connected to the two ends of the sliding component 1 55, the sliding component 1 55 is located between the two groups of elastic telescopic parts and is slidably provided with the sliding groove 567. In order to prevent the existence of sediment in the bottom pipe, the built-in spring 565 allows the sliding component 1 55 to freely expand and contract according to the situation of the concrete pipe 2, and provides a sliding effect.

[0031] The sliding assembly 1 55 includes a rotating shaft 568, a solid wheel 566 and two baffles 561. The solid wheel 566 of the sliding assembly 1 55 is connected to one end of the two springs 565 away from the bottom plate 563 through the rotating shaft 568. Two baffles 561 are arranged on the rotating shaft 568. The two baffles 561 are respectively located on both sides of the solid wheel 566 and between the two sets of elastic telescopic parts. The solid wheel 566 of the sliding assembly 1 55 can be freely extended and retracted along the radial direction of the working tube 4 while rotating and under the action of elastic force.

[0032] The two sets of sliding components 54 each include a rotating shaft 568, a solid wheel 566 and two baffles 561. The two baffles 561 of each set of sliding components 54 are arranged on the bottom wall of the bottom fastener 52. A solid wheel 566 is rotatably arranged between the two baffles 561 via the rotating shaft 568. The sliding components 54 play a role in assisting transportation.

[0033] Stiffening ribs 562 are provided on the sides of the two baffles 561 of the sliding assembly 1 55 and the sliding assembly 2 54 that are away from each other. The stiffening ribs 562 on the baffle 561 in the sliding assembly 1 55 are located on both sides of the bottom plate 563 .

[0034] In this embodiment, the top fastener 51 and the bottom fastener 52 are arc-shaped, and connecting plates 57 are respectively provided at both ends of the top fastener 51 and the bottom fastener 52. The arc of the arc structure of the top fastener 51 and the bottom fastener 52 matches the working pipe 4 and the concrete pipe 2. On the one hand, the bottom fastener 51 fits with the working pipe 4 to avoid damage to the working pipe 4 during transportation. On the other hand, it is convenient for the sliding component 1 55 and the sliding component 2 54 to move in the concrete pipe 2 along the normal direction of the working pipe 4.

[0035] Bolt holes 56 are correspondingly formed on the connecting plates 57 of the top fastener 51 and the bottom fastener 52 . Connecting components are arranged in the bolt holes 56 , and the connecting components include bolts 53 .

[0036] After the concrete pipe 2 is penetrated in the soil layer 1, the working pipe 4 is gently lifted into the concrete pipe 2 with a lifting device, and a conveying device 5 is installed at the end of the working pipe 4 and slowly translated into the concrete pipe 2. During the translation process, a conveying device 5 is installed every 5-10 meters until the working pipe 4 penetrates the entire concrete pipe 2. The device has a simple structure and effectively improves the problem of reduced working pipe construction efficiency caused by friction during the top pipe construction process. During the penetration process, the conveying device is easy and quick to install, and the working pipe 4 is delivered by rolling through the solid wheel 566, with low construction difficulty and high penetration efficiency. The use of the conveying device greatly improves the construction efficiency and reduces the construction period cost. At the same time, it can effectively avoid the pipeline performance and life problems caused by the friction of the pipe wall, and reduce the later pipeline maintenance costs. The sliding component is set to a telescopic type, which can be automatically adjusted according to the situation in the concrete pipe, and has a good use effect.

[0037] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model.
