Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a buried pipe pay-off device for water conservancy projects, which effectively solves the problem that the existing buried pipe pay-off method not only has low work efficiency, but also can cause problems when the cable is too long. When the pipe is bent, it is easy to bend in the pipe and cannot move forward in the pipe; if there is a foreign object in the buried pipe, it will not be possible to complete the work of laying out the buried pipe

Embodiment 1

[0034] Embodiment 1, the present invention is a buried pipe pay-off device for water conservancy projects, which includes an outer cylinder 1 with closed left and right ends, and the outer cylinder 1 provides a fixed foundation for the subsequent structure. It is characterized in that the outer cylinder 1 Square adjustment holes 2 are respectively opened on the front, rear, upper and lower sides, and the four adjustment holes 2 respectively pass through the side wall of the outer cylinder 1, and a square adjustment screw rod 3 is slidingly installed in the four adjustment holes 2, respectively. The screw rods 3 can slide radially around in the adjusting cylinder 2 at the same time. When the four adjusting screw rods 3 slide outward, the distance between the four adjusting screw rods 3 becomes larger, that is, the axis of the outer cylinder 1 to the adjusting screw rods 3 The distance from the top of the top is the radius. When the adjusting screw 3 slides, the radius changes ac...

Embodiment 2

[0038] Embodiment 2. On the basis of Embodiment 1, square telescopic holes 17 are respectively opened at the ends of the four adjustment screw rods 3 located outside the outer cylinder 1. The cross-sections of the four walking wheel shafts 4 are square and respectively Slidingly installed in the four telescopic holes 17, the telescopic springs 18 between the walking wheel shaft 4 and the telescopic holes 17 are installed respectively in the four telescopic holes 17, when the positions of the four adjusting screw mandrels 3 are adjusted, the four When a walking wheel 5 drives the outer cylinder 1 to walk in the buried pipe, if there is a protrusion or foreign matter on the inner wall of the pipe, the walking wheel shaft 4 can slide into the telescopic hole 17 and compress the telescopic spring 18. When passing through the protrusion or foreign matter Under the action of the telescopic spring 18, the traveling wheel shaft 4 slides outwards, so that the traveling wheel 5 walks clo...

Embodiment 3

[0039] Embodiment 3, on the basis of Embodiment 1, the tensioning device includes tensioning slide plates 27 fixedly installed on the inner wall of the outer cylinder 1 and respectively flush with the two sides of each transmission groove 23, and each group of Tensioning chute 28 in the left and right direction is respectively opened on the tensioning slide plate 27, and two tensioning wheels 29 are respectively slidably installed in the tensioning chute 28 described in each group, and the shafts of the two tensioning wheels 29 can respectively Slide left and right in the two tensioning chutes 28, the tensioning wheel 29 can rotate on the shaft, and the right end of each group of tensioning slides 27 is respectively fixedly equipped with a spring plate 30 perpendicular to the two tensioning slides 27, so The spring plate 30 runs through and is slidably installed with a tensioning spring bar 31 left and right, the tensioning spring bar 31 can slide left and right on the spring p...

Abstract

The invention provides a buried pipe pay-off device for water conservancy projects, which solves the problems of low working efficiency of the existing buried pipe pay-off method, and the problems that the cable is easily bent in the pipe and cannot move forward when the cable is too long; it includes an outer cylinder, an outer There are square adjustment holes on the front, rear, upper and lower sides of the cylinder respectively, and there are adjustment screw rods sliding in the four adjustment holes, one end of the four adjustment screw rods on the outside of the outer cylinder is respectively fixed with a walking wheel shaft, and the other ends of the four walking wheel shafts are respectively rotated There are walking wheels, and the inner wall of the outer cylinder is rotated with external tooth internal thread sleeves that are coaxial with the four adjustment screw rods and threaded. The adjusting ring gear is installed on the inner wall of the outer cylinder, and the adjusting drive gear meshing with the adjusting ring gear is installed on the inner wall of the outer cylinder; the present invention adopts a mechanical automatic transmission device, so that the work of laying out the buried pipe is automated, which not only improves the work efficiency, but also does not A problem occurs where the cable becomes stagnant in the duct.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a buried pipe setting-out device for water conservancy engineering. Background technique [0002] Water conservancy engineering is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating benefits, also known as water engineering; water is an indispensable precious resource for human production and life, but its natural existence The state does not fully meet the needs of human beings. Only by building water conservancy projects can water flow be controlled, floods prevented, and water volume adjusted and distributed to meet the needs of people's life and production for water resources. Water conservancy projects require the construction of dams, dikes, Spillways, sluices, water intakes, channels, aqueducts, raftways, fishways and other different types of hydraulic structures to...
