Abstract
Description
Technical Field
[0001] The utility model relates to a construction tool, in particular to a pipe pulling device. Background Art
[0002] During the civil construction process, some foundation pit fences are supported by steel pipes inserted into the soil. When the project is completed, these steel pipes inserted into the soil need to be pulled out and reused. How to develop a convenient pipe pulling tool to facilitate construction workers to complete the pipe pulling operation in a time-saving and labor-saving manner has become a problem that needs to be solved on site. Summary of the invention
[0003] The utility model provides a pipe pulling device, which solves the technical problem of how to conveniently pull out a steel pipe inserted into soil.
[0004] The utility model solves the above technical problems through the following technical solutions:
[0005] A pipe pulling device comprises a base plate, on which a column is fixedly arranged; a first hinge shaft is arranged at the top end of the column, a swing arm rod is hinged on the first hinge shaft, a handle is arranged at the right end of the swing arm rod, a second hinge shaft is arranged at the left end of the swing arm rod, a connecting rod is hinged on the second hinge shaft, a third hinge shaft is arranged at the other end of the connecting rod, an L-shaped clamping plate is hinged on the third hinge shaft, a sleeve is movably sleeved on the L-shaped clamping plate, a clamping rod is fixedly connected to the sleeve, the L-shaped clamping plate and the clamping rod form a clamp-shaped clamping mouth, and clamp adjusting screw holes are arranged at intervals and correspondingly between the sleeve and the horizontal rod of the L-shaped clamping plate, and bolts are inserted into the clamp adjusting screw holes.
[0006] The base plate is arranged on the soil ground, and a steel pipe with its lower part inserted into the soil is arranged on the soil ground on the left side of the base plate; the steel pipe is arranged in a clamp-shaped bayonet, and a rubber anti-skid pad is arranged in the clamp-shaped bayonet.
[0007] The utility model realizes the pulling out of the vertical steel pipe by means of the force transmission lever principle, can adapt to steel pipes with different diameters by adjusting the clamp-shaped bayonet, and is simple and labor-saving to operate on site. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the utility model;
[0009] Figure 2 It is a structural schematic diagram of the utility model when the steel pipe 2 is pulled upward for a section. DETAILED DESCRIPTION
[0010] The utility model is described in detail below with reference to the accompanying drawings:
[0011] A pipe extraction device comprises a base plate 3, on which a column 4 is fixedly arranged; a first hinge shaft 5 is arranged at the top end of the column 4, a swing arm rod 6 is hinged on the first hinge shaft 5, a handle 14 is arranged at the right end of the swing arm rod 6, a second hinge shaft 7 is arranged at the left end of the swing arm rod 6, a connecting rod 9 is hinged on the second hinge shaft 7, a third hinge shaft 8 is arranged at the other end of the connecting rod 9, an L-shaped clamping plate 10 is hinged on the third hinge shaft 8, a sleeve 12 is movably sleeved on the L-shaped clamping plate 10, a clamping rod 11 is fixedly connected to the sleeve 12, the L-shaped clamping plate 10 and the clamping rod 11 form a clamp-shaped clamp 15, and clamp adjustment screw holes are arranged at intervals and correspondingly between the sleeve 12 and the horizontal rod of the L-shaped clamping plate 10, and bolts 16 are passed through the clamp adjustment screw holes.
[0012] The base plate 3 is arranged on the soil ground 1 , and a steel pipe 2 with its lower part inserted into the soil is arranged on the soil ground 1 on the left side of the base plate 3 ; the steel pipe 2 is arranged in a clamp-shaped bayonet 15 , and a rubber anti-skid pad 13 is arranged in the clamp-shaped bayonet 15 .
[0013] According to the diameter of the steel pipe 2, the size of the clamp-shaped bayonet 15 is adjusted, and the bolt 16 is inserted into the corresponding bayonet adjustment screw hole to fix the clamp-shaped bayonet 15; the base plate 3 is placed on the soil ground 1 on the right side of the steel pipe 2 vertically inserted into the soil, the L-shaped clamping plate 10 is placed horizontally, and the clamp-shaped bayonet 15 is clamped on the upper part of the steel pipe 2; the operator swings the handle 14 downward to make the swing arm rod 6 swing clockwise around the first hinge shaft 5, and the second hinge shaft 7 drives the L-shaped clamping plate 10 and the clamping rod 11 to move upward through the connecting rod 9, so that the clamp-shaped bayonet 15 drives the steel pipe 2 to move upward for a distance; after the steel pipe 2 is pulled upward to a corresponding height, the handle 14 is lifted to make the clamp-shaped pipe clamp 6 in a horizontally relaxed state, and freely fall to a certain height, and then the vertical downward pressure on the handle 14 is repeatedly applied, and this action is repeated until the steel pipe 2 is pulled out from the soil ground 1.
