Description
Technical Field
[0001] This utility model relates to the field of municipal construction, and in particular to a tail support device for a pipe jacking machine. Background Technology
[0002] Pipe jacking machines are mechanical equipment used in municipal underground trenchless engineering. They are modern engineering construction equipment that can complete the laying of underground pipelines across highways, railways, rivers, ground buildings, underground structures, etc. without excavating the surface layer.
[0003] When a pipe jacking machine is used in construction, a support plate is usually fixed to the inner wall of the pipe jacking pit. The support plate is used as a pad, that is, the hydraulic seat at the tail of the pipe jacking machine is supported by the support plate, thereby protecting the inner wall of the pipe jacking pit.
[0004] However, the support plates in related technologies are usually made of a single steel plate, which is not conducive to the transportation and installation of the support plates by workers. At the same time, the installation of the support plates requires the use of large cranes for hoisting and multiple workers to work together, which not only increases construction costs but also poses safety hazards. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tail support device for a pipe jacking machine. It adopts a modular design, which facilitates the installation of the support device by workers, improves installation efficiency, and reduces safety hazards.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tail support device for a pipe jacking machine, comprising two horizontally arranged support rails, the opening sides of the two support rails being arranged opposite each other, and the two support rails being connected by a tensioning member, and a plurality of support plates being vertically arranged between the two support rails, the plurality of support plates being arranged sequentially along the length direction of the support rails, two adjacent support plates abutting each other, and the two side surfaces of the support plates being flush with the corresponding surfaces of the support rails, and a support block being integrally formed at the upper and lower ends of each support plate, and the support block being tightly inserted into the corresponding support rail.
[0007] In a preferred embodiment, the present invention can be further configured such that: multiple positioning columns are vertically fixedly connected to the two support rails respectively, the multiple positioning columns are arranged in a one-to-one correspondence with the multiple support blocks, each support block is provided with a positioning groove, and the multiple positioning columns can be inserted into the corresponding positioning grooves respectively.
[0008] In a preferred embodiment, the present invention can be further configured such that: a dovetail strip is provided on one side of the support plate and a dovetail groove is provided on the other side, and the dovetail strip matches the dovetail groove so that two adjacent support plates can be spliced and fixed.
[0009] In a preferred embodiment, the present invention can be further configured as follows: the tensioning member includes two vertically arranged tensioning rods, and a plurality of support plates are respectively located between the two tensioning rods. The bottom of each of the two tensioning rods is fixedly connected to a support base, and the support base is connected to the support rail located below by a plurality of fastening screws. The two ends of the support rail located above are respectively provided with mounting holes, the tops of the two tensioning rods respectively pass through the corresponding mounting holes, and the top of each tensioning rod is respectively threaded with a clamping nut.
[0010] In a preferred embodiment, the present invention can be further configured such that: each end of the two support rails is provided with an assembly hole through which expansion bolts pass.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Reference Figure 1 , Figure 2 A tail support device for a pipe jacking machine includes two horizontally arranged support rails 1, one above the other, with their openings facing each other, and connected by a tensioning member 2. Simultaneously, each end of the two support rails 1 has a through-hole 3 for expansion bolts to pass through, meaning the support rails 1 can be fixed to the inner wall of the pipe jacking pit by expansion bolts.
[0022] Reference Figure 2 , Figure 3 Multiple support plates 4 are vertically arranged between two support rails 1. The support plates 4 are arranged sequentially along the length of the support rails 1, with adjacent support plates 4 abutting against each other. The two side surfaces of the support plates 4 are flush with the corresponding surfaces of the support rails 1. At the same time, support blocks 5 are integrally formed at the upper and lower ends of each support plate 4, and the support blocks 5 are tightly inserted into the corresponding support rails 1.
[0023] Reference Figure 2 , Figure 3 Multiple positioning posts 6 are vertically fixedly connected to the two support rails 1. The multiple positioning posts 6 are set one-to-one with multiple support blocks 5. Each support block 5 is provided with a positioning groove 7, and the multiple positioning posts 6 can be inserted into the corresponding positioning groove 7 to realize the horizontal positioning of the support plate 4.
[0024] Reference Figure 2 , Figure 3 One side of the support plate 4 is provided with a dovetail strip 8 and the other side is provided with a dovetail groove 9, and the dovetail strip 8 and the dovetail groove 9 are matched so that two adjacent support plates 4 can be spliced and fixed, which can improve the connection stability between two adjacent support plates 4 and improve the structural stability of the support device.
[0025] Reference Figure 2 , Figure 3Each support block 5 is provided with a clearance groove 10, and a lifting ring 11 is fixedly connected in each clearance groove 10 for hooking with the lifting hook of the lifting equipment, so as to facilitate the lifting and transportation of the support plate 4 by the workers. At the same time, elastic buffer layers 12 are fixedly connected to both sides of each support plate 4 to protect the inner wall of the pipe jacking pit and reduce the risk of scratches on the inner wall of the pipe jacking pit.
[0026] Reference Figure 1 , Figure 2 The tensioning component 2 includes two vertically arranged tensioning rods 21, with multiple support plates 4 located between the two tensioning rods 21. Support seats 22 are fixedly connected to the bottom of each of the two tensioning rods 21, and the support seats 22 are connected to the lower support rail 1 via multiple fastening screws 23. Mounting holes 13 are provided at both ends of the upper support rail 1, and the tops of the two tensioning rods 21 pass through the corresponding mounting holes 13. A clamping nut 24 is threaded onto the top of each tensioning rod 21.
[0027] When the support device needs to be installed, the lower support rail 1 is connected to the inner wall of the jacking pit using expansion bolts. Then, the support seats 22 at the bottom of the two tension rods 21 are connected to the support rail 1 using fastening screws 23. Next, the first support plate 4 is installed on the support rail 1, that is, the support block 5 below the support plate 4 is inserted into the support rail 1, and the positioning groove 7 at the bottom of the support block 5 forms an interlocking fit with the corresponding positioning post 6. Immediately afterwards, the second support plate 4 is installed on the support rail 1, ensuring that the dovetail block between the two support plates 4 forms an interlocking fit with the dovetail groove 9. This process is repeated until all support plates 4 are installed in place.
[0028] Subsequently, the upper support rail 1 is installed above the multiple support plates 4, meaning that the support blocks 5 above each support plate 4 are respectively inserted into the support rail 1, and the positioning groove 7 on the top of each support block 5 is respectively engaged with the corresponding positioning post 6. The tops of the two tension rods 21 pass through the corresponding mounting holes 13. Next, clamping nuts 24 are installed on the tops of the two tension rods 21, and the clamping nuts 24 are tightened until they abut against the support rail 1. The rail is then connected to the inner wall of the jacking pit using expansion bolts, thus completing the installation of the support device.
