Abstract

The utility model relates to a U-shaped chassis high efficiency dynamic compaction machine. A left crawler belt and a right crawler belt of the U-shaped chassis are connected through a crossbeam. The intersection parts between the left crawler belt and the right crawler and the crossbeam are respectively provided with a left support and a right support. Furthermore the U-shaped chassis is connected with a trapezoidal truss through the hinge points on the crawler belts. The top of the trapezoidal truss is provided with a pulley block. A hoister is equipped on the crossbeam. A lifting wire rope on the hoister is connected with a suspension hook through a pulley block. The suspension hook is connected with a rammer. According to the utility model, as the U-shaped structure is used as the chassis and the supporting hinge points of the trapezoidal truss are provided above the crawler belts, non only is force bearing state of the chassis improved, but also the space in the chassis is enlarged. A purpose of lifting at the center of the inner part of rammer is realized. The defect in the cantilever structure of crane is overcome. The impact and vibration are remarkably reduced. Furthermore the stability of the whole machine is greatly improved.

Description

The efficient dynamic compaction machinery in U type chassis

Technical field

The utility model relates to the efficient dynamic compaction machinery in a kind of U type chassis.

Background technology

Dynamic compaction machinery is a kind of ground foundation reinforcement means of French Menard technology company in initiative in 1969, domesticly begin to apply in later 1990s, at present, domestic construction enterprises are mostly with medium and small tonnage (15-70 ton), and crawler crane increases the strong rammer operation that servicing unit realizes that 800 tons of rice energy levels are following.At present, be arm-type structure because crawler crane adopts, it is big to exist jerk load for the impact working method of this unexpected unloading of strong rammer, poor stability, the life-span is low, shortcomings such as maintaining difficulty.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, safe and reliable, the efficient dynamic compaction machinery in U type chassis being convenient to move.

In order to achieve the above object, the technical solution adopted in the utility model is: described U type chassis connects left and right crawler belt by crossbeam, be positioned at left and right crawler belt and the crossbeam intersection area is provided with left and right supporting, and join by hinge on the crawler belt and parallel chord truss, the parallel chord truss top is equipped with assembly pulley, hoist engine is installed on the crossbeam, and the hoist rope of hoist engine is connected with suspension hook through assembly pulley, and suspension hook is connected with hammer ram by detacher.

The utility model has the advantages that:

Because the chassis adopts the supporting hinge of U type structure and parallel chord truss to be positioned at the crawler belt top, not only improved the force-bearing situation on chassis, and enlarged the chassis volume inside, realized the purpose of hammer ram inside center lifting operation, overcome the defective that the jib boom structure exists, obviously reduced shock and vibration, and complete machine stability improves greatly.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that the A of Fig. 1 is to schematic diagram;

Fig. 3 is a U type chassis structure schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 3 as can be known, U type described in the utility model chassis connects left and

right crawler belt

11,10 by crossbeam 14, be positioned at left and

right crawler belt

11,10 and crossbeam 14 intersection areas and be provided with left and right supporting 12,13, and join by hinge on the crawler belt and parallel chord truss 2, parallel chord truss 2 tops are equipped with assembly pulley 9, hoist engine 1 is installed on the crossbeam 14, and the hoist rope of hoist engine 1 is connected with suspension hook 8 through assembly pulley 9, and suspension hook 8 is connected with hammer ram 6 by detacher 7.

By the parallel chord truss 2 that crossbeam bar 3 between four intilted main chords 5 and the main chord and diagonal member 4 are formed, each limit is trapezoidal forms triangular structure by main chord 5 and crossbeam bar 3 and diagonal member 4.

The utility model is because the chassis adopts the supporting hinge of U type structure and parallel chord truss to be positioned at the crawler belt top, not only improved the force-bearing situation on chassis, and enlarged the chassis volume inside, realized the purpose of hammer ram inside center lifting operation, overcome the defective that the jib boom structure exists, obviously reduced shock and vibration, and complete machine stability improves greatly.

The utility model car load is by rigidity U type chassis and parallel chord truss is hinged constitutes, and wherein the left and right crawler belt on U type chassis is furnished with drive unit, makes car load realize the on-the-spot walking of bearing a heavy burden, and promotes elevator and is connected with hammer ram by wire rope, assembly pulley, suspension hook, detacher.The utility model drives the lift work that elevator work realizes hammer ram by power-driven system.
