Abstract
The invention discloses a front leaning-resistance device for a forced ramming device, which comprises a fixed device, a buffer and a follow-up device, wherein the fixed device is a stretching beam the rear end of which is fixed on a main platform; the lower end of the buffer is hinged on the front end of the stretching beam; the upper end of an expansion link of the buffer is connected with the lower part of a rammer frame through a steel wire; and a steel cylinder of the buffer is connected on the main platform through the follow-up device. In the invention, the spring pretightening force in the buffer is adjusted through the length of the steel wire, so that the steel wire has higher strength of extension, has good adaptability, can be blended, and the length can be adjusted conveniently. The follow-up device is composed of a follow-up wire and a tensioned spring, can ensure the rotation of the buffer, prevent the damage to human and other loss because of falling down of the buffer caused by the loosen of steel wire at instant. The invention has reasonable design, simple structure, convenient installation and reliable work, solves the problem of the traditional leaning-resistance device, and is particularly suitable for the forced ramming device of different grades to use.
Description
One. technical field
The invention belongs to engineering machinery anti-dumping technical field, be specifically related to a kind of anti-tilt device of dynamic compaction machinery.
Two. background technology
Dynamic compaction machinery is used for the backfill compacting.Its operating principle is: after according to working condition requirement hammer ram being risen to predetermined altitude, detacher is thrown off hammer ram, the hammer ram free-falling, and the gravitional force with hammer ram in the dropping process is converted into kinetic energy, and kinetic energy is converted into ballistic work soft terrain is tamped when landing.Dynamic compaction machinery is in promoting the hammer ram process, and hammer ram is conducted oneself with dignity to ramming downward force of frame, makes the rammer frame produce elastic deformation downwards.When hammer ram is brought up to predetermined height, transfer suddenly, at this moment ram the downward elasticity of frame and be released, the rammer frame recoils backward and hits, and causes rammer frame and whole machine body to swing back and forth, and has produced fluctuating load, has influenced the application life of complete machine.Traditional solution is to install anti-tilt device additional in rammer frame back.Anti-tilt device is with the different steel pipe sockets of two diameters together, and the centre installs a compression spring additional, rams the frame swing to alleviate.But there is following problem in traditional anti-tilt device: select that the different steel strengths of two diameters are low for use, spring stiffness factor hour, alleviate that to ram frame swing effect bad, and the easy unstability of steel pipe; Select the different steel strength height of two diameters for use, when the spring stiffness factor is big because anti-tilt device is with to ram between the frame angle little, when a bit, anti-tilt device at this moment becomes a rigid body to length of spring compressed, causes the bending of rammer frame to certain.
The anti-tilt device that dynamic compaction machinery rams frame is continued to use anti-tilt device behind the crane always.Because the special operation condition of dynamic compaction machinery, back anti-tilt device can not satisfy the dynamic compaction machinery instructions for use fully.
Three. summary of the invention
The purpose of this invention is to provide the preceding anti-tilt device of a kind of dynamic compaction machinery, ram the frame vibration problems in the dynamic compaction machinery work to solve effectively, thus the application life of improving complete machine.
The technical solution used in the present invention is: anti-tilt device comprises fastening devices, snubber and hunting gear before the dynamic compaction machinery, it is characterized in that: its fastening devices is horizontal beam, horizontal beam rear end is fixed on the main platform, the snubber lower end is hinged on horizontal beam front end, the expansion link upper end of snubber is connected with rammer frame bottom by steel cable, and the steel cylinder of snubber is connected on the main platform by hunting gear.
Characteristics such as the present invention is by the length adjustment snubber medi-spring pretightning force of steel cable, and steel cable has advantages of higher tensile strength, and length adjustment is convenient, and servo-actuated is good, and is flexible.Snubber is made up of component such as steel cylinder, expansion link, springs.Its major function is to be connected steel cable tension snubber medi-spring with snubber by ramming frame, absorbs by length of spring compressed, elongation and rams the swing that frame produced.Hunting gear is made up of steel cable, extension spring.It both can guarantee that buffer rotated, and had prevented that again the personnel that cause injure and unknown losses owing to ram frame and be connected steel cable moment with buffer and relax and cause buffer to fall down to the ground.
The present invention is reasonable in design, and is simple in structure, easy for installation, reliable operation.Solved the problem that traditional sway bar device exists.The dynamic compaction machinery that is particularly suitable for different stage uses.

Five. the specific embodiment
Dynamic compaction machinery comprises main frame 1, anti-tilt device 2, rams frame 3, hammer ram 4 and detacher 5, and the anti-tilt device 2 of existing dynamic compaction machinery is the back sway bar that is made of different steel pipes of two diameters and spring, and back sway bar is connected with main frame in rammer frame back.Anti-tilt device 2 of the present invention is preceding anti-tilt devices, and it is that snubber is installed on the preceding beam that is fixed on the main platform, and the expansion link of snubber is connected by steel cable and rams on the frame.
Preceding anti-tilt device partly is made up of horizontal beam 7, snubber 8, hunting gear 9 three.Horizontal beam 7 rear ends are fixed on the main platform 6, and snubber 8 lower ends are hinged on horizontal beam 7 front ends, and the expansion link upper end of snubber 8 is connected with rammer frame 3 bottoms by steel cable 10, and the steel cylinder of snubber 8 is connected on the main platform 6 by hunting gear 9.
Hunting gear 9 constitutes by connecting extension spring with running rope, and the extension spring end is connected the steel cylinder upper end of snubber 8, is connected on the main platform 6 with running rope.
There is a pulley snubber 8 expansion links upper end, and steel cable 10 is enclosed within on this pulley, and the two ends of steel cable 10 are connected to be rammed on the frame 3.This device guarantees to connect two steel cable pulling force equalizations of ramming frame.
For the ease of transportation, horizontal beam 7 designs are dismantled and assembled.Horizontal beam 7 is divided into two joints, connects by flange between two joints, and the rear end of horizontal beam 7 is welded on the front of main platform 6, with bolt forward and backward horizontal beam flange is linked to each other.
The weldment of horizontal beam 7, snubber 8 is that common seamless steel pipe stiffened panel makes, and is simple in structure, is convenient to processing.
