Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the above-mentioned pile extractor places the base on the ground and uses the support provided by the ground to complete the pile extraction work, so it can only be used in environments with hard soil or poured concrete; When used in soft soil, the base is easy to sink into the soil layer, causing the base to be unstable, and it is difficult to give the hydraulic cylinder a good supporting force, which affects the pile pulling effect

Embodiment 1

[0037] Embodiment 1: refer to Figure 1-3 , is a pile extractor disclosed in the present invention, comprising a base 1 and a support frame 2, the support frame 2 is installed on the base 1 through a hydraulic cylinder 5 and moves up and down along the height direction of the base 1; the support frame 2 moves along the length direction of the base 1 The two sides of the two sides are symmetrically provided with a fixed frame 9 respectively, and the fixed frame 9 is welded on the base 1; Three groups of piles are adjacent to each other in the clamping soil layer; when the three clamping parts 13 are clamped and fixed with the corresponding pile bodies, the hydraulic cylinder 15 drives the support frame 2 to move upwards, driving the middle pile body out of the soil layer 6-8 meters; then move the base 1, drive the clamping part 1 on one side to clamp the pile body pulled out from the soil layer, and use the reaction force of the pulled out pile body and the pile body on the oth...

Embodiment 2

[0041] Embodiment 2: The difference from Embodiment 1 is that, with reference to figure 1 with 3 , the above-mentioned hydraulic cylinder one 5 is provided with two, two hydraulic cylinder one 5 are respectively arranged on both sides of the width direction of the base 1, the lower end of the hydraulic cylinder one 5 is fixed with a roller shaft 8, and the support frame 2 and the base 1 are respectively arranged along the length direction of the base 1. There is provided a chute 6 for insertion of the telescopic shaft and the roller shaft 8 and linear movement, and the movement of the hydraulic cylinder one 5 is restricted by a limiting member.

[0042] The above-mentioned limiting parts include the limiting groove 1 provided on the base 1 and the support frame 2 respectively corresponding to the axes of the hydraulic cylinder 2 37 and the hydraulic cylinder 3 43, the telescopic shaft of the hydraulic cylinder 1 5 and the limiting groove 2 provided on the roller shaft 8, When...

Embodiment 3

[0044] Embodiment 3: The difference with Embodiment 1 is that, with reference to image 3 with 4 , the support block 1 35, clamping block 1 34, support groove 1 36 and hydraulic cylinder 2 37 in the above clamping member 1 3 are evenly arranged in six groups along the center of the pile body, and the six groups of clamping block 1 34 surround a circle ; Among them, two groups of clamping blocks 134 arranged symmetrically along the width direction of the base are flat on the side facing the pile body, and the other four groups of clamping blocks 134 are curved on the side facing the pile body.

[0045] refer to Figure 5 , in this embodiment, one end of the above-mentioned clamping block 34 in the supporting groove 36 is set on an inclined surface whose upper side is narrower than the lower side, and the inner wall of the supporting block 35 abuts against the inclined surface of the clamping block 34, giving clamping Hold block one 34 facing forward with lower stress.

Abstract

The invention relates to a pile pulling machine which comprises a base and a supporting frame. First clamping parts used for clamping or loosening pile bodies of piles are arranged on the supporting frame. The at least three sets of first clamping parts are arranged in the length direction of the base. The middle set of first clamping parts is used for lifting the piles, the two sets of first clamping parts on the two sides are clamped on the piles on the two sides, and a supporting function is provided for the base. The middle set of first clamping parts shifts up and down relative to the base through first hydraulic cylinders, and the first clamping parts on the two sides are arranged on fixed frames and are fixed to the base through the fixed frames. The pile pulling machine has the effects that counter acting force is provided through the adjacent piles, and the pile pulling machine can be operated and used by adapting to different geographical environments.

Description

technical field [0001] The invention relates to the technical field of pile pulling machines, in particular to a pile pulling machine. Background technique [0002] Pile extractor is to utilize the power of hydraulic cylinder 1 to pull out the pile machinery of stratum with circular pipe pile, I-beam, Larsen steel sheet pile at present. [0003] Existing such as figure 1 A pile extractor shown includes a base, a hydraulic cylinder and a support frame. Two hydraulic cylinders are arranged symmetrically along the width direction of the base. , to drive the support frame to move up and down. Two support plates are fixed at the lower end of the support frame. The support plates are correspondingly arranged on both sides of the pile body. The two support plates are also correspondingly opened with through holes, and the through holes are inserted with bolts passing through the pile body. The support frame is located above the support plate and is provided with two clamping bloc...
