Description

The crawler belt spring tension holding device of heavy construction equipment

Technical field

The present invention relates to the crawler belt spring tension holding device (a track spring tension maintenance apparatus for a construction heavy equipment) of heavy construction equipment; In more detail; Relate in using the process of heavy construction equipment if the tension force of crawler belt spring descends, then cylinder body is automatically injected lubricating oil and recover the device of the tension force of crawler belt spring.

Background technology

Generally speaking, (Track Shoe Ass ' y) is flexibly supported by the crawler belt spring assembly and stretches within the specific limits the creeper tread assembly of heavy construction equipment, thereby relaxes the impact in the driving process.

Fig. 1 representes the longitudinal section of the crawler belt spring assembly of relevant heavy construction equipment of the present invention.

As shown in Figure 1; The crawler belt spring assembly 100 that flexibly supports creeper tread assembly adopts following form etc.; Be connected with free gear at cylinder body 110 crawler belt spring 130 is set between the carriage 120; Have inject runner 141 piston 140 to the left and right direction be arranged on the inside of cylinder body 110 movably, be incorporated into cylinder body 110 a side axle 150 to the left and right direction is connected carriage 120 connections movably with free gear.

The free gear of above-mentioned crawler belt spring assembly 100 connects carriage 120 and combines with the free gear of mobile devices, and above-mentioned piston 140 is fixedly installed on the crawler frame.

In above-mentioned crawler belt spring assembly 100; If the injection runner 141 through being arranged at piston 140 injects lubricating oil to the inside of cylinder body 110; Then cylinder body 110 and axle 150 move to free gear connection carriage 120 directions because of the pressure of lubricating oil; Crawler belt spring 130 connects carriage 120 and free gear pressurization to free gear simultaneously along with cylinder body 110 mobile is compressed and moves it, thereby to the creeper tread assembly that contacts with free gear tension force is provided.

And in the process that heavy construction equipment goes, the crawler belt spring 130 through above-mentioned crawler belt spring assembly 100 absorbs the impact that is applied on free gear and the analog bracket.

But; In the process that heavy construction equipment was worked at the scene in the past; It is not enough that the leakage of the cylinder body 110 in-to-in lubricating oils (Grease) that cause owing to the process along with the time, the tension force of crawler belt spring 130 become, thereby frequently produce the sagging phenomenon of creeper tread assembly.

So existence need be carried extra lubricating oil and oiling machine (Gun) and come cylinder body 110 problem of make-up oil is at any time existed in the work very loaded down with trivial details problem of actual job site to cylinder body 110 make-up oils.

In said structure; If cylinder body 110 abundant make-up oils are not caused the tension force of crawler belt spring 130 not enough; Then produce the inordinate wear etc. of crawler belt associated components, thereby cause reduce the endurance life of crawler belt associated components owing to the interference between underframe (Under carriage) parts such as the disengaging of creeper tread assembly or lower rollers, upper roll, crawler belt protector, crawler frame and the creeper tread assembly.

Summary of the invention

The present invention makes in view of the situation of aforesaid prior art; Its purpose is to provide the crawler belt spring tension holding device of heavy construction equipment; This device can make the tension force of crawler belt spring and creeper tread assembly keep certain; Thereby in the process of heavy construction equipment work, can prevent the disengaging of creeper tread assembly, and can prolong the endurance life of chassis component.

In order to achieve the above object, the crawler belt spring tension holding device of heavy construction equipment of the present invention is characterised in that, lubricating oil auto-supply device is set on the piston of crawler belt spring assembly, thereby to cylinder interior supplying lubricating oil automatically.

Promptly; The crawler belt spring tension holding device of heavy construction equipment of the present invention has the crawler belt spring assembly; This crawler belt spring assembly is connected with free gear at cylinder body and is provided with the crawler belt spring between the carriage; Direction is provided with movably and has the piston that injects runner to the left and right in the inside of cylinder body, be incorporated into cylinder body a side axle to the left and right direction is connected the carriage connection movably with free gear, thereby flexibly support creeper tread assembly; The crawler belt spring tension holding device of above-mentioned heavy construction equipment is provided with lubricating oil auto-supply device on above-mentioned piston; Thereby when the tension force of crawler belt spring is not enough,, the tension force of crawler belt spring is increased, can make the tension force of crawler belt spring keep certain thus cylinder body supplying lubricating oil automatically.

In the crawler belt spring tension holding device of heavy construction equipment of the present invention; Lubricating oil auto-supply device can constitute with following form; One side possesses lubricating oil packing space portion in the inside of housing; Central interior at housing is provided with increased pressure board, and opposite side is provided with the pressure regulating spring that increased pressure board is pressurizeed in the inside of housing, and the injection connection pipe that is arranged at a side of lubricating oil packing space portion is connected with the injection runner of piston.

In addition, the electric press regulating mechanism of controlling through other control mechanism is installed on the increased pressure board of lubricating oil auto-supply device, increased pressure board is pressurizeed and to the cylinder body supplying lubricating oil through the electric press regulating mechanism.

In the crawler belt spring tension holding device of heavy construction equipment of the present invention, on the injection runner of piston, be provided with and be used to prevent the check valve of the lubricating oil of cylinder body to lubricating oil auto-supply device side adverse current.

The present invention has following beneficial effect.

Crawler belt spring tension holding device according to heavy construction equipment of the present invention; In the process of using heavy construction equipment; If the oil leak of cylinder body and cause the tension force of crawler belt spring and creeper tread assembly to descend; Then by lubricating oil auto-supply device to cylinder body supplying lubricating oil and make the tension force of crawler belt spring keep certain automatically; Therefore disengaging not only can be prevented, and the endurance life of underframe (Under carriage) parts such as lower rollers, upper roll, crawler belt protector, crawler frame can be prolonged because of the not enough creeper tread assembly that causes of tension force of crawler belt spring.

And the operator does not need with the naked eye to confirm at any time the tension force of crawler belt spring and at any time to the cylinder body supplying lubricating oil, operator's the comfort feature that therefore can be improved, and can increase substantially the effect of the functional and commodity etc. of heavy construction equipment.
