Abstract
The utility model discloses a machine body shield limiting device. The machine body shield limiting device comprises a slide rail, an inverted-U-shaped supporting rod, and slide blocks respectively fixed at two ends of the inverted-U-shaped supporting rod. The slide rail is longitudinally fixed in the middle of one side of a machine body shield and provided with a longitudinal long sliding groove, two ends of the long sliding groove respectively extend out of a first limiting hole and a second limiting hole, the diameter d1 of the first limiting hole and the second limiting hole is larger than the width b of the longitudinal long sliding groove, the sliding block at one end of the inverted-U-shaped supporting rod is connected with the longitudinal long sliding groove in a sliding mode, and the other end of the inverted-U-shaped supporting rod is connected with an underbed on a machine body in a hinged mode through the slide blocks. When the machine body shield starts locking, the sliding block at one end of the inverted-U-shaped supporting rod slides into a lower limiting hole in the slide rail and limits the machine body shield in a supporting mode. When the machine body shield stops locking, the sliding block at one end of the inverted-U-shaped supporting rod falls into the second limiting hole in the slide rail. The machine body shield limiting device is simple in structure, safe, reliable, simple and convenient to operate, timesaving and laborsaving, and the sliding block at one end of the inverted-U-shaped supporting rod is reliable in limiting.
Description
Technical field
The utility model relates to a kind of fuselage guard shield of engineering machinery, and especially a kind of stopping means of engineering machinery fuselage guard shield belongs to technical field of engineering machinery.
Background technology
Excavator is engineering machinery the most frequently used in the engineering construction, and its working environment is very abominable, and able to turn on or off fuselage guard shield can prevent effectively that dust foreign material etc. from entering excavator base machine inside, and protection motor and hydraulic transmission etc. are not damaged.When excavator detects or keep in repair, need to open the fuselage guard shield and it be supported fixing.Existing fuselage guard shield support limit mechanism structure is complicated, and it is spacing unreliable that fuselage guard shield unlatching rear pole locks, and in a single day the strut locking lost efficacy, and the fuselage guard shield drops suddenly, very easily personnel is damaged.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, strut and locks spacing reliable fuselage guard shield stopping means.
The utility model is achieved by the following technical programs:
A kind of fuselage guard shield stopping means, comprise slide rail, inverted U-shaped strut and be separately fixed at the slide block of termination, inverted U-shaped strut two ends, described slide rail is vertically fixed in fuselage guard shield upside or lower middle side part, slide rail is provided with vertical long chute, vertically long chute two ends extend outward respectively the first spacing hole and the second spacing hole, described the first spacing hole or the second spacing hole diameter d 1 are greater than vertical long chute width b, inverted U-shaped strut one end slide block slidably is connected with described vertical long chute, and the inverted U-shaped strut other end is hinged by slide block and fuselage underframe one side; When the fuselage guard shield was opened, inverted U-shaped strut one end slide block fell into slide rail the first spacing hole, with fuselage guard shield support limit; When the fuselage guard shield was closed locking, inverted U-shaped strut one end slide block fell into slide rail the second spacing hole.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid fuselage guard shield stopping means, wherein said slide block is the little multidiameter structure in large centre, two, comprise block, lower block, be positioned at the limited block of block below and the jackshaft that connects limited block and lower block, described limited block diameter d 2 is less than the first spacing hole and the second spacing hole diameter d 1.
The utility model is simple in structure, and the strut locking is reliable.When opening the fuselage guard shield, inverted U-shaped strut one end slide block along the longitudinal long chute slides, until the connection limited block of slide block falls into the inverted U-shaped strut of slide rail the first spacing hole locking, the fuselage protective guard lock fixes on opening, can detect and keep in repair excavator.When closing the fuselage guard shield, on lift inverted U-shaped strut, connect limited block and break away from slide rail the first spacing hole, along with closing of fuselage guard shield, the jackshaft of slide block slides along the vertical long chute of slide rail, until inverted U-shaped strut one end slide block falls into slide rail the second spacing hole, the fuselage protective guard lock fixes on closed condition, and inverted U-shaped strut locking is reliable.Easy and simple to handle, time saving and energy saving.
Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the utility model fuselage guard shield opening front view;
Fig. 2 is the I section enlarged drawing of Fig. 1;
Fig. 3 is the top view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Such as Fig. 1～shown in Figure 3, the utility model comprises slide rail 1, inverted U-shaped strut 2 and be welded on respectively the slide block 3 of termination, inverted U-shaped strut 2 two ends, slide rail 1 is vertically fixed in fuselage guard shield 4 upsides or lower middle side part, slide rail 1 is provided with vertical long chute 11, vertically long chute 11 two ends extend outward respectively the first spacing hole 12 and the second spacing hole 13, the first spacing hole 12 is identical with the second spacing hole 13 diameters, its diameter d 1 is greater than vertical long chute width b, inverted U-shaped strut 2 one end slide blocks 3 longitudinally long chute 11 slide, and the slide block 3 of inverted U-shaped strut 2 other ends is hinged with fuselage underframe 5 one sides.Slide block 3 is the little multidiameter structure in large centre, two, comprise block 31, lower block 32, be positioned at the limited block 33 of block 31 belows and the jackshaft 34 that connects limited block 33 and lower block 32, the diameter d 2 of limited block 33 is less than the diameter d 1 of the first spacing hole 12 and the second spacing hole 13, being convenient to limited block 33 falls in the first spacing hole 12 or the second spacing hole 13, during fuselage guard shield 4 open locking, inverted U-shaped strut 2 one end slide blocks 3 fall into the first spacing hole 12 of slide rail 1, with fuselage guard shield 4 support limit; When fuselage guard shield 4 was closed locking, inverted U-shaped strut 2 one end slide blocks fell into slide rail 1 second spacing hole 13.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
