Abstract
An reinforced walking system of a laying caterpillar comprises a loop wheel machine, an compensating beam and a machine frame, wherein the front of the machine frame is rigidly fixed to a box beam by a support and fasteners, the two side of the back of the machine frame are fixed to a loop wheel machine support by a support and fasteners. Based on a 320-horse-power caterpillar bulldozer, the utility model adopts rigid connection between the machine frame and the lop wheel machine to eliminate the problem that prior caterpillars swing left and right in the process of turning, which remarkably improves the stability of the whole machine in operation and satisfies the stability of plural cooperating machines. By increasing the quantity of thrust wheels and widening apron wheels, the contact area between the walking system and the ground is increased and specific pressure is decreased, thereby the utility model can adapt to various operating modes and the strength and the weight of the machine frame is reinforced on the basis of a prior machine frame, which increases the carrying capacity of the laying caterpillar and makes the laying caterpillar safe and reliable in operation.
Description
Technical field
The utility model relates to the running gear of pipe sling, particularly laying tractor heavier-duty running gear.
Background technology
Pipe sling is the specialized equipment that oil and natural gas pipeline is laid, and in recent years, because China is to the vigorous development of energy demand, the construction of natural fuels and petroleum pipe line has also obtained fast development, and the pipe sling of big caliber 90t--100t series is had demand.Because the lifting amount is big, this series pipe sling requires very high to running gear.Consider that from the applying working condition and the lifting amount of pipe sling whole running gear must be firm, also will play the counterweight effect.The running gear of pipe sling comprises crawler type chassis and vehicle frame at present, vehicle frame adopts elastic element to be erected on the crawler type chassis with semi-rigid hang, and occur swinging when adopting semi-rigid hang to cause pipe sling to turn to easily, when making the complete machine operation, stability is bad.
The width of existing in addition pipe sling crawler belt is not enough, causes the counterweight and the intensity that can not increase driving system.
The utility model content
The purpose of this utility model is on 320 horsepowers of crawler doer bases and propose a kind of laying tractor heavier-duty running gear, to solve present laying tractor running gear built on the sand, can not be suitable for problems such as several work operating mode.
The utility model solves the problems referred to above by the following technical programs, reaches goal of the invention of the present utility model.
A kind of laying tractor heavier-duty running gear comprises chassis, equalizing bar and vehicle frame; Described chassis comprises the left and right hub that links to each other with the semiaxis upper bracket by bearing cap shim, and caterpillar wheel is installed the box girder of caterpillar wheel and is looped around crawler belt on drive sprocket, the caterpillar wheel; It is characterized in that the front portion of described vehicle frame is rigidly fixed on the box girder by bearing and fastener, the both sides, rear portion are fixed on the chassis bearing by bearing and fastener.
The quantity of described caterpillar wheel is nine.The width of described crawler belt is 760-860mm.
The utility model is on 320 horsepowers of crawler doer bases, by taking being rigidly connected of vehicle frame and chassis, the problem that swings that has existed when having eliminated existing pipe sling and turning to, thereby the stability when having improved the complete machine operation greatly, the stability when having satisfied multiple devices work compound.Quantity by increasing caterpillar wheel and add broad track, running gear and contact area of ground are increased, reduce specific pressure, make it to adapt to various operation operating modes, whole vehicle frame all can strengthened on intensity and weight on the original basis, the pipe sling bearing capacity is increased, safe and reliable.Because 320 horsepowers of every performance figure of crawler doer satisfy the operating needs of 90t pipe sling, and its maximum hoisting moment reaches 117t.m (1.3m), thereby can satisfy the requirement of 90t pipe sling fully.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the front view of running gear described in the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the E-E cutaway view of Fig. 1.
Fig. 4 is the F-F cutaway view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
The utility model is transformed on 320 horsepowers of crawler doer bases and is formed.
Referring to Fig. 1 to Fig. 4, a kind of laying tractor heavier-duty running gear, comprise chassis 1, equalizing bar 2 and vehicle frame 4, A place in Fig. 1, the left and right hub of chassis 1 links to each other with the semiaxis upper bracket by bearing cap shim, specifically how bonded assembly is well known to those of ordinary skill in the art, is not described in detail at this.By such connection mode, the oscillating axle axle center of chassis 1 overlaps with the drive sprocket center, and when vehicle cleared the jumps, load additional in the driving section of crawler belt 5 was less.Chassis 1 also comprises caterpillar wheel 6, the box girder 7 of caterpillar wheel 6 is installed and be looped around crawler belt 5 on drive sprocket, the caterpillar wheel 6, C place in Fig. 1 and D place and Fig. 3, vehicle frame 4 pass through bearing 3 and fastener is rigidly fixed on the box girder 7, as the following contact surface of equalizing bar 2 and box girder 7 bolt togethers of interior contact surface and chassis 1, equalizing bar 2 is rigidly connected with vehicle frame 4 bearings.B place and Fig. 4 in Fig. 1, both sides, vehicle frame 4 rear portion are by bearing 3 and be bolted on chassis 1 bearing.Equipment installation in the past and the bad shortcoming of maintainability have been changed.The vehicle frame 4 of whole running gear is connected on the chassis 1 by three place's rigidity, chassis 1 and vehicle frame 4 form rigid frame structure, the problem that swings that exists when eliminating pipe sling and turning to, thereby the stability when having improved the complete machine operation greatly, the stability when having satisfied multiple devices work compound.
According to pipe sling operating environment and the big requirement of actual measurement weight (AMW), the utility model increases to 760-860mm with the width of the crawler belt 5 of running gear, simultaneously caterpillar wheel 6 is increased to nine from seven, makes crawler belt 5 and ground contact surface increase, reduce specific pressure, made it to adapt to various operation operating modes.Whole vehicle frame is all being strengthened on intensity and weight on the original basis, and chassis uses steel plate to use thickening type, and weld seam is obviously strengthened, and makes the swing pipe function bear 90 tons hoisting weight, and is safe and reliable.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
