Abstract

The utility model relates to a sleeve-type double anti-tilt bar compaction mechanism which comprises an intermediate arm and a lower segmental arm, wherein the intermediate arm is hinged with the upper end of a main anti-tilt bar; the lower end of the main anti-tilt bar is hinged with an A-shaped frame; the A-shaped frame is hinged with the lower end of an auxiliary anti-tilt bar; and the upper end of the auxiliary anti-tilt bar is hinged with the lower segmental arm. With the double anti-tilt bar structure including the main and the auxiliary anti-tilt bars, the utility model solves the problem of mechanical limiting safety of the arm support of the compaction machine during the amplitude-variable motion and the problem of rebound buffer function of the arm support during the compaction process. Besides, the main anti-tilt bar adopts the hinge seat-type connection mode and the hinge shaft-type connection mode, in which an inner support rod of the main anti-tilt bar can pass through an outer support rod hinge seat in a sliding manner, and a spring is arranged on the inner support rod, so as to solve the problem that the travel of the inner support rod is restricted by the two end hinge shaft connection mode and the problem of rebound buffer function of the arm support during the compaction process. The utility model is convenient for installation, enhances the buffer effect during the compaction process, and improves safety.

Description

Telescopic pair of sway bar rammed Working mechanism by force

Technical field

The utility model belongs to mechanical field, is specifically related to a kind of strong rammer Working mechanism.

Background technology

The operating principle of dynamic compaction machinery: be that the hammer ram of certain tonnage is brought up to corresponding height, allow its free-falling then, potential energy is converted into kinetic energy, it is based on power densification theory, by the percussion of hammer ram to the soil body, air in the soil is overflowed, soil body particle rearranges, reduce the void ratio of the soil body, reduce the compressibilty of the soil body, eliminate its settlement by soaking, increase the dry density of the soil body, improve bearing capacity of foundation soil, be widely used in civilian construction, airport construction, petrochemical industry storage base, the harbour, harbour, the stockyard, commonly used in the market have two class dynamic compaction machineries: based on shovel crawler chassis refit mechanical type dynamic compaction machinery and, use crawler crane repacking carrying out ramming operation dynamic compaction machinery.And common strong rammer Working mechanism has two kinds: 1. as shown in Figure 1, comprise secondary sway bar 5, secondary sway bar 5 upper ends are hinged on down on the joint arm 8, the lower end is hinged on the A type frame 7, this Working mechanism is owing to have only one group of pair sway bar mechanism 5, when ramming operation by force,, cause the generation of damage of jib early fatigue even jib overthrow accident, can not get assurance at capacity utilization and secure context because the jib bounce-back acutely can not get abundant buffering.2. as shown in Figure 2, comprise main sway bar 2, main sway bar 2 upper ends and intermediate arm 9 are hinged, lower end and A type frame 7 are hinged, the sway bar that all adopts the twisted axis formula to be connected with the jib centre position on the A type frame in this structure, when the ramming operation, can play the effect of jib bounce-back buffering, the dynamic compaction machinery that can be used for medium and small tonnage, but because the large-tonnage dynamic compaction machinery is limited by space structures, if sway bar adopts traditional two ends twisted axis formula to connect, when the jib horizontal level is installed, can cause in the main sway bar, outer pole is separated, only when the jib change angle is spent the left and right sides greater than 30, install, increase installation difficulty and danger.

The utility model content

The technical problems to be solved in the utility model is that the use of existing strong rammer Working mechanism is dangerous, provides a kind of and uses telescopic pair of safer sway bar to ram Working mechanism by force.

The technical solution of the utility model realizes in the following manner:

A kind of telescopic pair of sway bar rammed Working mechanism by force, comprises intermediate arm and saves arm down, and the upper end of intermediate arm and main sway bar is hinged, and the lower end of main sway bar and A type frame are hinged, and A type frame and secondary sway bar lower end are hinged, and secondary sway bar upper end is with the joint arm is hinged down.

Described main sway bar comprises inner supporting rod and outer pole, and outer pole and A type frame are hinged, and the inner supporting rod upper end is hinged with intermediate arm, and inner supporting rod is arranged in the outer pole, and inner supporting rod 1 upper end is arranged with spring.

The utility model adopts major and minor pair of sway bar structure, solves the dynamic compaction machinery jib and is carrying out the spacing safe problem of luffing movable machinery; And the problem of jib bounce-back cushioning effect during the ramming operation.Main in addition sway bar adopts the twisted seat formula to be connected with the twisted axis formula, its inner supporting rod can pass outer pole twisted seat end and slide, inner supporting rod is provided with spring, has solved the problem of jib bounce-back cushioning effect when the inner supporting rod stroke is subjected to two ends twisted axis formula connected mode restriction and ramming operation.The utility model simple installation, ramming operation enhancing buffering effect is obvious, safety is higher.

The specific embodiment

As shown in Figure 3, originally be that intermediate arm 9 is hinged with the upper end of main sway bar 2 with novel intermediate arm 9 and the following joint arm 8 of comprising, the lower end of main sway bar 2 and A type frame 7 are hinged, and A type frame 7 is hinged with secondary sway bar 5 lower ends, and secondary sway bar 5 upper ends are hinged with following joint arm 8.As shown in Figure 4, described main sway bar 2 comprises inner supporting rod 11 and outer pole 10, and outer pole 10 is hinged with A type frame 7, and inner supporting rod 11 upper ends and intermediate arm 9 are hinged, and inner supporting rod 11 is arranged in the outer pole 10, and inner supporting rod 11 upper ends are arranged with spring 18.

Shown in Fig. 5～8, A type frame is provided with A type frame twisted seat 14 and A type frame otic placode hole 15, wherein A type frame twisted seat 14 and outer pole 10 are hinged, A type frame otic placode hole 15 links to each other with secondary sway bar lower end twisted axis 12, secondary sway bar upper end twisted axis 13 links to each other with joint arm otic placode hole 17 down, and intermediate arm otic placode hole 16 links to each other with twisted axis on the inner supporting rod 11.Avoid in the jib operation process causing the generation of jib overthrow accident because of tractor driver's maloperation makes the excessive lifting of jib, and in the strong jib auxiliary cushioning effect that rebounded when ramming operation.

In the utility model, inner supporting rod 11 slides in the pole 10 outside, makes the stroke of winner's sway bar 2 no longer restricted, and inner supporting rod 11 upper ends are provided with spring 18, in the time of ambient pressure hour, under the effect of spring 18 restoring forces, inner supporting rod 11 upwards slides along outer pole 10.Make jib luffing in 0～80 ° of scope can not cause the disengaging of inside and outside pole.
