DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0026] First embodiment

[0027] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A schematic structural diagram of a first embodiment of a trenchless pipe laying and expanding machine provided by the utility model; Figure 2 for Figure 1 The trenchless pipe laying and expanding machine comprises:

[0028] Chassis assembly 4;

[0029] A clamp assembly 5, wherein the clamp assembly 5 is arranged on the top of the base frame assembly 4;

[0030] Two racks 6, the two racks 6 are arranged inside the chassis assembly 4, and one side of the two racks 6 is respectively arranged on both sides of the inner wall of the chassis assembly 4;

[0031] The rotary return support assembly 3 is arranged on the top of the base frame assembly 4, two rotary motors 1 are arranged on one side of the rotary return support assembly 3, and a feed motor 2 is arranged on one side of the rotary return support assembly 3.

[0032] The feed motor 2 is arranged between the two rotary motors 1 to save the space in the well to the maximum extent.

[0033] The function of the clamp assembly 5 is to support the drill rod to achieve horizontal drilling.

[0034] The function of the rotary support assembly 3 is to disengage the reaming head from the horizontal hole.

[0035] The working principle of the trenchless pipe laying and expanding machine provided by the utility model is as follows:

[0036] During operation, the rotary motor 1 drags the rotary return support assembly 3 and the reaming head back to one end of the rack 6, and then the rotary return support assembly 3 and the reaming head are dragged back to the other end of the rack 6 through the feed motor 2, and then the reaming head is taken out from between the two racks 6 to complete the reaming and realize the trenchless construction of the network pipe.

[0037] Furthermore, by changing the output direction of the vertically arranged feed motor 2 to horizontal output through gears, the vertically arranged feed motor 2 does not occupy too much space in the well. When a feed motor 2 with greater power needs to be replaced, it only occupies the vertical space, thus meeting the construction requirements in more environments.

[0038] Compared with the related art, the trenchless pipe laying and expanding machine provided by the utility model has the following beneficial effects:

[0039] The utility model provides a trenchless pipe reaming machine, which saves space in the well to the maximum extent by arranging a feed motor 2 between two rotary motors 1. At the same time, the feed racks 6 are arranged on both sides of the base frame assembly 4, leaving the middle space for expanding the space for accommodating the reaming head during back dragging. The rotary motor 1 drags the rotary return support assembly 3 and the reaming head back to one end of the rack 6, and then drags the rotary return support assembly 3 and the reaming head back to the other end of the rack 6 through the feed motor 2, and then takes out the reaming head from between the two racks 6. The rotary return support assembly 3 is used to facilitate the reaming head to be removed from the horizontal hole, thereby facilitating the reaming head to be taken out from between the two racks 6.

[0042] Specifically, the difference of the trenchless pipe laying and expanding machine provided in the second embodiment of the present application is that, in the trenchless pipe laying and expanding machine, a support sleeve 11 is provided on the surface of the base frame assembly 4, a movable plate 10 is fixedly connected to one side of the support sleeve 11, and a fixing hole 12 is provided inside the support sleeve 11.

[0043] Four support sleeves 11 are fixedly connected to one side of the movable plate 10 , and the top and one side of the four support sleeves 11 are through openings for facilitating the insertion of four mounting frames fixedly connected to the bottom of the chassis assembly 4 into the interior of the four support sleeves 11 .

[0044] A through slot is formed in the middle of the support plate 8 .

[0045] A support plate 8 is disposed on one side of the movable plate 10 , a support frame 7 is disposed at one end of the support plate 8 , and a movable groove 9 is formed inside the support plate 8 .
