Description

Lever type movable pile cutting machine

Technical field

The utility model is related to CFG cuts a device, and in particular, it is related to a kind of lever Mobile pile cutting machine.

Background technology

CFG head（Hereinafter referred to as CFG pile crowns）Mixed by rubble, aggregate chips, sand, flyash and cement plus water Afterwards, the concrete-pile with some strength being pressed into using forming machinery.In actual use, pile crown squeeze into ground it Afterwards, it is necessary to by Partial Resection above ground level.The universal processing mode of CFG pile crowns is abolishes, with minitype cutting machine along surrounding Pile crown is cut, 3 ~ 5cm of depth of cut, drilled with electric drill with three faces of 120 ° of deciles, then carried out with chock disrumpent feelings Processing；To the pile crown of surface irregularity, stake top repaired using small-sized pneumatic pick smooth.

Conventional pile cutting machine which disclose one kind and cut stake as shown in the patent that Authorization Notice No. is CN202012081U Machine, including base, be connected the handrail for setting and being upwardly extended below base with base, and the one end of base away from handrail is provided with and cuts stake Blade, blade are connected on base by main shaft, and tire is additionally provided with base.In use, people promotes pile cutting machine along stake Head is rotated, and pile crown is cut.Due to needing artificial promote to be cut around pile crown when cutting pile crown, artificial is difficult that control is each The position of secondary cutting pile crown, pile cutting machine is bigger, and workmen's promotion is relatively elaborate, is also not easy to cut flat with pile crown.

Utility model content

The purpose of this utility model is to provide a kind of lever type movable pile cutting machine, set close to the position of pile cutting tool piece Expansion link, the position of fixed pile crown, frame, which is provided with swing handle driving, cuts stake and saws and moved to pile body, and it is more laborsaving to cut stake, stake The section of body is also more smooth.

Above-mentioned purpose of the present utility model technical scheme is that：A kind of lever type movable cuts stake Machine, including frame, one end of frame are provided with the handle for promoting pile cutting machine, and one end away from handle, which is provided with, cuts stake saw, is set in frame There is driving to cut the motor that stake saw rotates, universal wheel is provided with below frame, is stretched in frame close to the position rotation connection for cutting stake saw Bar, saw coaxial fixed drive in frame and cut stake with cutting stake and saw the handle rotated to expansion link；Expansion link includes and gantry rotation The outer loop bar of connection, and be threadedly coupled with outer loop bar, the L-shaped interior bar for clamping pile body.

Using above technical scheme, one end of frame, which is fixed with, cuts stake saw, with cutting the coaxial fixed handle of stake saw.Leaned in frame The nearly position rotation connection expansion link for cutting stake saw.Expansion link, frame and the cavity for cutting stake saw one U-shaped of composition, stake to be cut Body is stuck in the cavity of U-shaped and cut.When cutting, pile cutting machine is pushed into specified location, stake saw is cut in startup, with pile body and L-shaped The contact point of interior bar is fulcrum, holds handle and rotates frame to expansion link direction, and pile body is cut along pile body radial direction.

Expansion link include threaded connection outer loop bar and L-shaped interior bar, by rotate L-shaped interior bar can adjust cut stake saw and L The distance between shape interior bar, to adapt to the pile body of different-diameter.Handle is coaxial fixed with cutting stake saw, increases the arm of force, conveniently cuts stake. Radial cut stake of the stake saw along pile body is cut, section is more smooth.

The utility model is further arranged to, and L-shaped interior bar includes the threaded rod being threadedly coupled with outer loop bar, and and screw thread The vertical clamping bar for clamping pile body of bar.

Using above technical scheme, the threaded rod of L-shaped interior bar is as expansion link distance adjusting means, and threaded rod is towards frame Direction rotates, and the distance between clamping bar and frame reduce, and adapts to the less pile body of diameter.Threaded rod rotates away from frame direction When, the increase of the distance between clamping bar and frame, use the pile body being relatively large in diameter.

The utility model is further arranged to：Reinforcement is provided between threaded rod and clamping bar.

Using above technical scheme, pile body is stuck between clamping bar and frame, connecing with pile body and clamping bar when cutting Contact is fulcrum, is connected to reinforce threaded rod with clamping bar, and reinforcement is set between threaded rod and clamping bar.

The utility model is further arranged to, and expansion link is located at the both sides of frame with stake saw is cut respectively.

Stake saw is cut using above technical scheme, when cutting to move towards expansion link direction, by expansion link and is cut stake saw and is split In the both sides up and down of frame, avoid cutting stake saw and interfered with expansion link.

The utility model is further arranged to, and the universal wheel is at least three.

Using above technical scheme, universal wheel is arranged on bottom of the frame, moving frame when conveniently cutting.In order to ensure to consolidate Mobile support, universal wheel are at least set to three, while forming stable support, are also convenient for moving.

The utility model is further arranged to, and is cut side of the stake saw away from expansion link and is set shield.

Using above technical scheme, when cutting, stake saw high-speed rotation is cut, people is hurt in order to avoid cutting a sawing stake mistiming, Cutting side of the stake saw away from expansion link, shield is set.

In summary, the utility model has the advantages that：Stretched in frame close to the position rotation connection for cutting stake saw Contracting bar.When cutting, using pile body and the contact point of L-shaped interior bar as fulcrum, hold handle and rotate frame to expansion link direction, along pile body Radial direction cuts pile body, arm of force increase, it is more laborsaving to cut stake.In addition, expansion link can stretch to adapt to the stake of different-diameter Body.
