Abstract

The utility model relates to a double-roller soil compacting machine tracked by traction machinery used for earthwork compacting construction. The utility model is composed of a towing bracket with a draw-hook, and a frame provided with a roller. The deadweight tonnage is increased manyfold through fillingsteel ball groups with different diameters in the roller, and additionally, the buffer device arranged between the draw-hook and the towing bracket adopts a demountable connection mode with the towing bracket and the frame. The utility model is especially suitable for the clay soils with the requirement of large compacting density and depth, and the earthwork construction containing a large amount of gravels and weathered stone, and is convenient for turning and rotary transport in narrow areas.

Description

Double-roller soil compacting machine

The utility model relates to a kind of Double-roller soil compacting machine, and it is dragged by hitching machinery and is used for a cubic metre of earth compacting construction.

At present domestic at highway, the earthwork compacting in the earthwork constructions such as earth dam generally all is to adopt the light face to roll static roller and vibrating roller.The light face rolls that its roller of road roller area contiguously is big, and unit pressure is little, only be suitable for the soil layer of compacting pine shop 20-25cm thickness, and it rolls number of times and link is more, and operating efficiency is not high.Vibrating roller only is suitable at non-sticky soil and the thin clayed soil roller compaction construction of individual layer compacted depth, and limitation is bigger.A kind of sheepfoot roller of existing domestic use, by the poker that on roller, is provided with, the double effects that in construction, soil layer is had static(al) compacting and deep layer wedge reality, but it adopts conventional loading method (adding water or sandstone in roller), make that machine volume is big and deadweight tonnage still less (4～6 tons) is undesirable to the soil layer consolidation effect that loose laying depth is bigger.

The purpose of this utility model be to overcome above-mentioned the deficiencies in the prior art and provide a kind of volume little, simple in structure, change loading method the deadweight tonnage be multiplied, be particularly useful for the big fine grain clayed soil of the requirement compacted density and the degree of depth and contain a large amount of days gravels and the Double-roller soil compacting machine of the earthwork construction of land waste, be convenient to turn tune and transition transportation in narrow place.

The purpose of this utility model is achieved in that a kind of Double-roller soil compacting machine, and it comprises the bracket with towing hook, and the framework of roller is housed, and is separately fixed at broach and poker tooth on framework and the roller, and its special character is to be fitted with loading ball group in roller.

Above-mentioned loading ball group is made up of the steel ball of two or more different-diameters at least, and it can be three kinds or multiple.The steel ball of selecting for use is fitted in the roller according to a certain percentage, thereby makes the roller of the certain volume deadweight tonnage that has been multiplied.

In order to slow down the destruction of shock loading, between towing hook and bracket, also be provided with the buffer of forming by spring, sliding sleeve, the packing ring that is embedded with cushion rubber bumper and nut to the connector between bracket and framework and roller shaft, block bearing.Bracket is connected with framework by securing member, is convenient to the dismounting transportation like this.In frame rear portion balancing weight is housed also, in order to equalization frame.

The utility model has the advantages that: compare with 6 tons of sheepfoot rollers of existing domestic maximum, under the situation that volume reduces, the deadweight tonnage can reach more than 20 tons.Because deadweight is multiplied, its disposable pine shop is rolled soil thickness and can be reached more than the 50cm, be adapted to the roller compaction construction of large-scale ground works especially, can play very significant effect at aspects such as the efficient that improves mechanized, reduction expense for using mechanical equipment, reductions of erection time, add the buffer and the detachable drawing frame structure of setting, in construction of narrow place and transition transportation, more show its superiority compared with similar products.

Fig. 1 is the utility model overall structure schematic diagram.Fig. 2 is the vertical view of Fig. 1.

Below in conjunction with accompanying drawing the utility model most preferred embodiment is further described: the bracket (12) with towing hook (18) is fixed on a side of the framework (2) that is provided with broach (3) by securing member (as bolt) (13), the roller (5) that is provided with poker tooth (4) is installed in the bearing (7) on the framework by the roller shaft on it (6), described roller is two rollers, be symmetricly set on the steel ball (9), (10), (11) that are fitted with two or more different-diameters in the framework upper roller, steel ball can be packed into by the dress ball hole on the roller.For reinforcing roller, in roller, can add many supports (8).Towing hook is connected with bracket by buffer, buffer is by the sliding sleeve (16) that is contained on the towing hook neck, being contained in spring (17) between sliding sleeve, packing ring (15) that an end is embedded with cushion rubber bumper and nut (14) forms upper reinforcing plate (19) and lower reinforcing plate (20) is housed on bracket, upper and lower stiffener one end is overlapped on the framework, and pass through bolton, the remainder of upper and lower stiffener can be fixed on the bracket, at the opposite side with respect to bracket of framework, balancing weight (1) is housed also.

The utility model is dragged by hitching machinery can carry out rolling operation.
