Technical Field

The invention relates to a sliding self-locking structure of a frame sealing plate of an excavator, and belongs to the technical field of hydraulic excavators.

Background

The crawler-type hydraulic excavator is a single bucket hydraulic excavator adopting a crawler walking chassis, and mainly comprises an upper turning platform and a lower turning platform. Wherein, the rotary platform of getting on the bus is provided with a cab, a power system, a hydraulic system, a shed and the like, and the walking part of getting off the bus comprises a lower frame, a track, a thrust wheel, a supporting chain wheel, a driving wheel and the like. The upper turning platform realizes the relative rotation of the upper vehicle and the lower vehicle through the central turning joint. Meanwhile, a hydraulic oil hose of the upper turning platform is connected to a driving motor of the lower turning part through a central turning joint, and hydraulic oil is conveyed to the lower turning part through the hose, so that the functions of complete machine running and the like are realized.

Usually, excavator frame access hole passes through the bolt and fixes the shrouding on frame bottom plate, when needs overhauld pipeline and central swivel joint of getting off, needs to demolish end shrouding fixing bolt completely, and need pull down the shrouding totally or partially, and shrouding thickness is 5 ~ 10mm usually, and to large-tonnage excavator, its shrouding weight reaches dozens of kilograms usually or even hundreds of kilograms, and the dismantlement process is both wasted time and energy, and is unsafe again.

Generally, the current excavator frame manhole mainly comprises an integral sealing plate and a split sealing plate. The integral sealing plate is completely fixed on the frame bottom plate through bolts, and the sealing plate can be detached only after all the bolts on the periphery are detached during maintenance; in addition, split type shrouding fixed knot constructs, will former integral shrouding divide into two parts, and one of them part realizes the partial opening of shrouding through the hinge point, but the fixed portion of this shrouding form still passes through the bolt fastening at the frame bottom.

The fixed form of current shrouding, before overhauing the operation, must demolish the frame shrouding totally or partially, can't realize overhauing the high efficiency of process shrouding and open. In addition, the common sealing plate fixing structure can only detach the sealing plate after all the fixing bolts are unscrewed, and the detached sealing plate can only be carried to the ground and cannot be temporarily stored on the frame. After the overhaul operation is completed, at least two persons are needed to cooperate to realize the re-fixation of the sealing plate, so that the time and the labor are wasted, and the safety risk exists.

Detailed Description

The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.

As shown in fig. 1 to 5, the invention provides a sliding self-locking structure of a frame sealing plate of an excavator, which comprises a frame bottom plate 6, wherein two parallel slideway supporting plates 2 are arranged below the frame bottom plate 6, a sealing plate assembly 1 is arranged between the two slideway supporting plates 2 and the frame bottom plate 6, the sealing plate assembly 1 comprises two sealing plates 1-1 which are oppositely arranged, the sealing plate 1-1 is semicircular in shape, and a handle 1-5 is connected below the sealing plate 1-1. The whole shape of the sealing plate assembly 1 is semicircular, and the sealing plate assembly is symmetrically arranged relative to the bottom maintenance hole of the frame to form a protection structure of the bottom maintenance hole of the frame bottom plate 6.

Locking blocks 1-2 and cushion blocks 1-4 are respectively arranged below two ends of the inner side of the sealing plate 1-1, guide blocks 1-3 are respectively connected below the locking blocks 1-2 and the cushion blocks 1-4, oblong slideways 2-1 are respectively arranged on the left side and the right side of the slideway supporting plate 2, the width of each guide block 1-3 is slightly smaller than the width of each oblong slideway 2-1 on the slideway supporting plate 2, after the sealing plate assembly 1-1 is installed, the guide blocks 1-2 are arranged in the slideways in the slideway supporting plate 2, the guide blocks 1-3 slide left and right along the oblong slideways 2-1, and locking pieces matched with the locking blocks 1-2 are arranged above the slideway supporting plate 2.

First thread seats 3 are arranged at the two ends of the slide supporting plate 2, second thread seats 5 are arranged at the middle of the slide supporting plate 2, self-tapping thread holes are formed in the first thread seats 3 and the second thread seats 5, the first thread seats 3 and the second thread seats 5 are fixed on the frame bottom plate 6 in a welding mode, bolts penetrate through mounting holes in the slide supporting plate 2 and then are connected with the first thread seats 3 and the second thread seats 5 respectively, and locking pieces are arranged on the second thread seats 5.

As shown in fig. 4, the locking member is an index pin 4, and the index pin 4 is fixed in a threaded hole at the top of the second threaded seat 5 through threads. The indexing pin 4 is a universal part, the end part of the indexing pin is provided with a movable pin 4-1, when the pin 4-1 is extruded, the pin 4-1 can retract into the indexing pin 4, and when the extrusion force disappears, the pin is extended again under the action of a return spring force in the indexing pin 4. The inner end of the locking block 1-2 is provided with a convex part 1-2-2 which is connected integrally, a locking channel for accommodating the convex part 1-2-2 is arranged in the second thread seat 5, a locking hole 1-2-1 is arranged on the convex part 1-2-2, and the pin 4-1 extends to clamp the locking hole 1-2-1.
