Description

Excavating machine frame suspender

Technical field

The utility model belongs to the lifting field, particularly excavating machine frame lifting appliance.

Background technology

In recent years, the excavating machine industry was in China's fast development, will carry out handling to vehicle frame in the maintenance of excavating machine and assembling process.Use the lifting of two leg hook-type riggings under the current background, have following drawback: 1. the vehicle frame of every kind of model need be joined a kind of suspender, and commonality is poor, and composing room needs standby many cover suspenders can satisfy operating needs.2. owing to rely on suspension hook opening upper surface to contact the location with the workpiece finished surface, during lifting machinework face there is certain damage, so that the matching property variation of the machinework face of workpiece.3. hoisting point position is grasped by manual, the suspension centre skewness often occurs and locates the unreliable potential safety hazard that exists.Present above-mentioned drawback is anxious to be resolved.

The utility model content

The utility model is intended to overcome the defective of prior art, and a kind of highly versatile is provided, and the excavating machine frame suspender of lifting safety and steady, can be widely used in the excavating machine manufacture.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

Excavating machine frame suspender, comprise suspension ring, compacting rope sling, suspension hook, it is characterized in that, also comprise slide block and litter support, connect three compacting rope slings on the described suspension ring, each described compacting rope sling one end is flexibly connected by shackle and suspension hook, on each described suspension hook a slide block is installed, the litter support comprises three litter, and each described suspension hook is all by the slide block litter sliding block joint corresponding with.

The other end that described compacting rope sling connects suspension ring is equipped with buckle, and the described compacting rope sling other end is equipped with the attaching parts of connecting bore.

Described suspension hook is made of two plate bodys and the slide block that is movably connected between two plate bodys, and described suspension hook top is provided with connecting bore, and described suspension hook bottom has the suspension hook opening to center position.

Described litter support is that three litter that radially distribute are welded to form, and welds in twos connecting rod between the litter, and the litter outside face is orbital plane, and the litter outside face slidely connects slide block, in described litter carriage center the center plectane is installed.

Compared with prior art, the utlity model has following beneficial effect:

The utility model commonality is wide, realizes that a plurality of vehicle frame one cover suspenders are general, simple to operate, and suspension centre is located automatically, lifts by crane more steady, safety, makes the excavator frame lifting convenient and swift; Can not damage hanging the thing finished surface in the lifting process.This invention can be widely used in the excavating machine manufacture, has a extensive future, and is the desirable regeneration product of present China excavating machine frame suspender, has widely promotional value.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.

Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 5, excavating machine frame suspender, comprise suspension ring 1, compacting rope sling 2, suspension hook 3, slide block 4 and litter support 5, in crown block hook 7 suspentions suspension ring 1 are arranged, connect three compacting rope slings 2 on the suspension ring 1, the other end that compacting rope sling 2 connects suspension ring 1 is equipped with buckle, and compacting rope sling 2 one ends are equipped with shackle 6, and shackle 6 ends have connecting bore.One end of each described compacting rope sling 2 is flexibly connected by the bolt in the connecting bore and suspension hook 3, suspension hook 3 is made of two plate bodys 31 and the slide block 4 that is movably connected between two plate bodys, described suspension hook 3 tops arrange bolt hole, and suspension hook 3 bottoms have the suspension hook opening 32 to center position.On each described suspension hook 3 slide block 4 is installed, has the litter hole on the slide block 4, adopt between slide block 4 and suspension hook 3 bodies to be flexibly connected, slide block 4 can freely rotate to adapt to different lifting angles.

As shown in Figure 3, litter support 5 comprises three litter 51, described litter support 5 is that three litter that radially distribute 51 are welded to form, weld in twos connecting rod 52 between the litter, the litter outside face is orbital plane, the litter outside face slides in the litter hole of slide block 4 through corresponding processing and processing, in described litter carriage center center plectane 53 is installed.Each described suspension hook 3 is all by slide block 4 litter 51 sliding block joints corresponding with.

Litter support 5 is rigid support, and three litter 51 evenly distribute, and every litter 51 outside faces of litter support are orbital plane, and suspension hook 3 slides along orbital plane.Because three litter evenly distribute, so that suspension hook can both distribute by even angle when being in any state.Centripetal three suspension hooks of component can keep hooking state when relying on the suspender lifting.Because the suspended object suspension centre is distributed on the regular circular flange and center of gravity overlaps with the litter support center of circle, so litter carriage center plectane 53 will be aligned suspended object flange center, just can guarantee that three suspension hooks evenly distribute when suspension hook hooks again.

The utility model three leg hook type riggings add sliding rod rack, make the rigging aperture automatically adjustable, and three suspension hooks evenly distribute, thereby the commonality that has improved rigging makes more convenient to operate.

Because suspension hook opening size, suspender are subjected to force line, are hung the relative position difference of flange in the suspension hook mouth, so that this suspender can both guarantee that the fulcrum that flange contacts has exceeded line of action of force below suspension hook when the suspended object of lifting in any regulatory specifications, suspension hook 3 can only oriented inner rotary tendency, suspension hook opening 32 upper surfaces do not contact (see figure 4) with the suspended object upper surface, have so just guaranteed that the suspended object finished surface is not damaged by pressure.Again owing to adopted 3 liftings and litter support with three suspension hook associations together, occuring when suspension hook is subject to external impacts to slide also is that three suspension hooks slide simultaneously around center of gravity, suspension centre does not change with respect to center-of-gravity position, so total energy keeps suspension hook to contact with the effective of flange, thereby guarantee that lifting is steady, safety.

The above only is explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
