Abstract
The utility model relates to a crawler type multifunctional towing machine, which comprises a vehicle body, a large arm hinged with the vehicle body, a hoisting sheave mounted on the end of the large arm, two sets of crawler belts, two crossbeams for mounting the crawler belts and a hydraulic motor; the upper end of a variable amplitude support is hinged with the vehicle body under the large arm; the rear end of a support variable amplitude oil cylinder is hinged with the vehicle body; the piston rod of the support variable amplitude oil cylinder is extended from the cylinder and hinged with the lower end of the variable amplitude support; the lower end of the variable amplitude support is contacted with the ground to realize more stable support to the vehicle body. When the crawler type multifunctional towing machine tows a slope roller, the support on the ground improves the stability of the vehicle body effectively; when the towing machine inclines forwards, a solenoid valve triggering rod is moved up by the thrusting force from the ground to trigger the shake-up to open, then the a hoister solenoid valve is closed, the hoister stops, the pulling force of a suspension hook is reduced, and the vehicle body is reset, thereby the stability of the vehicle body is maintained; the hoisting sheave is reinforced on both sides, can bear a radial force and an axial force at the same time, thereby solves the problem of hoisting sheave damage caused by the complex pressures caused by towing vibrations.
Description
Technical field
The utility model relates to a kind of crawler-type multifunctional tractor, and it is to belong to length in the engineering construction apart from hitching machinery.
Background technology
Side slope extensively is present in the middle of nature and the engineering, as flood control dam, hillock or the like.Slope stability is people's questions of common concern, and the compaction rate of slope soil is to influence its stable key factor.In the slope treatment practice, side slope rolls and can effectively increase soil body compactness, improves its stability.Side slope roll need function admirable length apart from hitching machinery.At present, multiple side slope rolls hitching machinery and has been applied in widely in the slope treatment engineering, for slope treatment has been made very big contribution.
But, in the slope treatment practice,, need the big slope of deadweight rolling machine in order to obtain good side slope rolling effect.Because the rolling machine fuselage is heavier, makes tractor stability very poor relatively like this, and toppling of hitching machinery taken place easily, threaten the safety of operating personnel and plant equipment.Therefore, there is the not enough shortcoming of stability in existing hitching machinery, can not satisfy the needs of slope treatment construction fully.
Summary of the invention
The purpose of this utility model is to provide a kind of crawler-type multifunctional tractor at the weak point of existing hitching machinery, improves the hitching machinery self stability, guarantees the safety of operating personnel and plant equipment, and reaches the improvement requirement.
The utility model purpose is realized by following technical scheme:
A kind of crawler-type multifunctional tractor, big arm, the head sheave that is installed on big arm end, the two cover crawler belts that comprise vehicle body, are hinged with vehicle body, two crossbeams that crawler belt is installed and hydraulic motor, it is characterized in that having the upper end of a luffing support and described vehicle body to be hinged, place the below of described big arm, there are the rear end of the cylinder block and the vehicle body of a support amplitude oil cylinder to be hinged, the piston rod of support amplitude oil cylinder stretches out cylinder body and is hinged with the bottom of described luffing support, during the kiss the earth of luffing support lower end vehicle body is formed and increases steady support.
Install shake-up electromagnetic valve and touch pole thereof additional in luffing support bottom in the utility model, the touch pole middle part adds the adjustable limiting switch, and the adjustable limiting switch links to each other with the shake-up electromagnetic valve, touches electromagnetic valve and links to each other with the hoist engine electromagnetic valve by circuit.
Head sheave is equipped with girth member in the utility model: radially circumferentially uniformly in the head sheave both sides add 8 HRB33518mm round bars.
The utility model compared with prior art, have following conspicuous outstanding substantive distinguishing features and remarkable advantage: the utility model adopts the crawler-type multifunctional tractor that has the luffing support, tractor is when the rolling machine of traction slope, and support lands, and improves the stability of vehicle body effectively; When tractor leaned forward, the touch pole that touches electromagnetic valve was moved up by ground thrust, and touch electromagnetic valve and be opened, hoist engine closed electromagnetic valve then, hoist engine just quits work, and the suspension hook pulling force reduces, and makes the vehicle body return keep its stability; Head sheave adopts the both sides reinforcement measure, when head sheave is subjected to radial load, also can be subjected to axial force, has solved effectively to drag wrong pressure of shaking to cause head sheave to damage.
Description of drawings
Accompanying drawing 1 is the structural representation of an embodiment of the utility model.
Accompanying drawing 2 is that the head sheave of Fig. 1 example is reinforced schematic diagram.
The specific embodiment
In conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in further detail: referring to Fig. 1, this crawler-type multifunctional tractor, comprise vehicle body 1, big arm 6 with vehicle body 1 hinge, be installed on the head sheave 8 of big arm 6 ends, two cover crawler belts 10, two crossbeams 9 and the hydraulic motor of crawler belt 10 are installed, there are the upper end and the described vehicle body 1 of a luffing support 2 to be hinged, place the below of described big arm 6, there are the rear end of the cylinder block and the vehicle body 1 of a support amplitude oil cylinder 7 to be hinged, the piston rod of support amplitude oil cylinder 7 stretches out cylinder body and is hinged with the bottom of described luffing support 2, during luffing support 2 lower end kiss the earths vehicle body 1 is formed and increases steady support.
Install shake-up electromagnetic valve 5 and touch pole 3 thereof additional in luffing support 2 bottoms, touch pole 3 middle parts add adjustable limiting switch 4, and adjustable limiting switch 4 links to each other with shake-up electromagnetic valve 5, touches electromagnetic valve 5 and links to each other with the hoist engine electromagnetic valve by circuit; Referring to Fig. 2, above-mentioned head sheave 8 has girth member 11; Radially circumferentially uniformly in head sheave 8 both sides add 8 HRB33518mm round bars.When rolled on the tractor slope, luffing support 2 landed, and had improved vehicle body 1 stability effectively; When tractor leaned forward, electromagnetic valve touch pole 3 was moved up by ground thrust, and touch electromagnetic valve 5 and be opened, hoist engine closed electromagnetic valve then, hoist engine just quits work, and the suspension hook pulling force reduces, and makes the vehicle body return keep its stability.
