Abstract
The invention provides a caterpillar band tensioning device which is characterized in that bosses (6) are symmetrically arranged on opposite faces of two opposite support seats (1), a guide bolt (5) is arranged between the two bosses (6), a steel spring (4) is sleeved on the guide bolt (5), the end portions of the steel spring (4) are connected with the bosses (6), the inner surface of an outer ring spring (2) and the outer surfaces of inner ring springs (3) are matched to form an annular spring, the inner ring springs (3) at two ends of the annular spring are tightly attached on the support seats (1) and are fixed on the bosses (6) of the support seats (1). The caterpillar band tensioning device can tension a caterpillar band anytime, the caterpillar band is in a certain tensioning state all the time, and damage to a caterpillar band chain caused by sudden impact force can be effectively lowered. The caterpillar band tensioning device is mainly used in walking parts of an excavator, a bulldozer, a crane and the like which are provided with a caterpillar band structure.
Description
Technical field
The invention belongs to technical field of engineering machinery, particularly have the construction machinery and equipment of crawler type walking mechanism.
Technical background
Track unit has the good characteristics such as tractive force is large, hill climbing ability is strong, turn radius is little, grounding pressure is low, thereby be widely used in fields such as construction machinery and equipment, mining machinery, vehicle for constructions, track unit particularly obtains general application in big-and-middle-sized self-propelled machinery, as machineries such as trench cutting machine, excavating machine, drillers.And Caterpillar belt tightening device has a great impact crawler travel performance tool.In the prior art, the main method of tensioner crawler belt comprises spring swelling method, oil cylinder tensioner method, screw rod tensioner method.If wherein adopt the spring swelling method, owing between the elastic force of spring and its scantling of structure, certain proportionate relationship being arranged, spring undersized, its insufficient rigidity is to remain on crawler belt the state of tensioner; Spring is oversize, because the restriction of crawler belt physical construction is difficult for installing and using.And adopt oil cylinder and screw rod tensioner method, and because the good rigidly of oil cylinder and screw rod is not yielding, when crawler belt was subject to impulsive force, crawler belt can not keep it to be at any time the tensioner state, and the effect of its tensioner will be had a strong impact on.Therefore, be necessary to invent a kind of Caterpillar belt tightening device of new structure.The present invention relates to the Caterpillar belt tightening device of new structure, particularly relates to the Caterpillar belt tightening device of the traveling gear of the construction machinery and equipment such as excavating machine, is mainly used between the positioning plate on the guide wheel of different horsepower traxcavators and chassis.Play the effect of tensioner, buffering, can improve the burst impulsive force to the destruction of crawler belt link by actv..
Summary of the invention
The purpose of this invention is to provide a kind of Caterpillar belt tightening device, it can effectively solve and keep at any time it to be in the problem of tensioner state in the crawler travel process.
The present invention realizes its goal of the invention, realized by following technical scheme: a kind of Caterpillar belt tightening device, the opposite face of two relative supporting seats is arranged with boss, is provided with guide bolt between two boss, on guide bolt, cover has steel spring, and the end of steel spring is connected with boss; The inside face of outer ring spring and the outside face of inner ring coupling forms annual spring, and the inner ring at annual spring two ends is close to supporting seat and is fixed on the boss of supporting seat.
During use, supporting seat is connected with swelling device mount pad on the crawler belt longeron to be got final product.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can play the effect of tensioner crawler belt at any time, makes crawler belt remain certain tensile force.Make crawler belt can keep certain tension force all the time, but actv. improve the impulsive force of burst, reduces the destruction to caterpillar chain.
Take ring-like cluster spring structure as main load bearing component, play the effect of buffering, tensioner, long service life; Need swelling device to remain certain tension force tensioner crawler belt during due to crawler travel, consider that annual spring restores slow problem, at the inner steel spring of placing of annual spring, can guarantee like this expanding force of caterpillar chain, resume speed is fast simultaneously.After the steel spring fracture failure, annual spring still can play the effect of tensioner and impact-absorbing, has avoided the direct impact to caterpillar chain of losing efficacy and to cause due to steel spring, the service life of having improved caterpillar chain.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the Caterpillar belt tightening device structural representation of invention.
The specific embodiment
Embodiment
Fig. 1 illustrates, one embodiment of the present invention are: a kind of Caterpillar belt tightening device, the opposite face of two relative supporting seats 1 are arranged with between boss 6, two boss 6 and are provided with guide bolt 5, on guide bolt 5, cover has steel spring 4, and the end of steel spring 4 is connected with boss 6; The outside face of the inside face of outer ring spring 2 and inner ring 3 coupling forms annual spring, and the inner ring 3 at annual spring two ends is close to supporting seat 1 and is fixed on the boss 6 of supporting seat 1.
Supporting base 1 can adopt the process of processing after first forging blank, has improved the intensity of supporting seat 1, and the contact position of supporting base 1 and annual spring 2 and steel spring 4 is carried out machinework, can guarantee each other better more flat contact.
Supporting seat is connected with swelling device mount pad on track beam whole swelling device can be packed on crawler belt, and allow whole device be in its pre-compressed state can to produce tensioner and buffer action.Its principle of work is: outwards promote the track adjusting wheel of crawler belt by the predetermincd tension of this swelling device, thereby make the outer in-migration tensioner crawler belt of guide wheel of crawler belt.Like this, can guarantee that guide wheel slides to change wheelspan along track frame, guarantee the dismounting of crawler belt, reduce the impact of walking process, avoid the derailing of rail chain.The technique of ring expansion after annual spring employing forging blank, the conical suface that processing coordinates after heat treatment, the grade of finish of conical suface directly affects the service life of annual spring and the degree of absorption power.
Claims (1)
1. Caterpillar belt tightening device, it is characterized in that: the opposite face of relative two supporting seats (1) is arranged with boss (6), be provided with guide bolt (5) between two boss (6), the upper cover of guide bolt (5) has steel spring (4), and the end of steel spring (4) is connected with boss (6); The outside face of the inside face of outer ring spring (2) and inner ring (3) coupling forms annual spring, and the inner ring (3) at annual spring two ends is close to supporting seat (1) and is fixed on the boss (6) of supporting seat (1).
