Abstract
The utility model discloses a connecting structure of a work device of a digging machine. The work device comprises a digging hopper, a hopper rod and a movable arm, wherein both ends of the hopper rod are respectively hinged with the digging hopper and the movable arm, the bottom of the movable arm is hinged with an upper turntable, and wear-resistance plates are arranged on all support end surfaces among each hinge part between the hopper rod and the digging hopper, between the hopper rod and the movable arm and between the movable arm and the upper turntable. The connecting structure can prevent the abrasion generated by direct contact of each component of the work device, and the trouble for replacing the components of the work device can be avoided. When the wear-resistance plates are abraded after being used for a certain time, only the wear-resistance plates need to be replaced, so a large amount of time can be saved, the efficiency can be improved, and meanwhile, the cost can also be saved.
Description
Technical field
The utility model relates to the construction machinery in a kind of building foundation engineering, is specifically related to a kind of syndeton of digger operating device.
Background technology
Excavator claims excavation machinery (excavating machinery) again, is to excavate with scraper bowl to be higher or lower than the material that holds machine side, and the haulage vehicle or unload earth moving plant to rickyard of packing into.The material that excavates mainly is soil and the rock behind soil, coal, silt and the pre-pine of process.From the development of engineering machinery in recent years, the development of excavator is very fast relatively, and excavator has obtained widespread usage as one of topmost engineering machinery type in the engineering construction.
Existing excavator mainly comprises equipment, top turntable and walking mechanism, and described equipment comprises scraper bowl, dipper and swing arm, and the two ends of dipper are hinged with scraper bowl, swing arm respectively, and the bottom of swing arm and top turntable are hinged.During excavator work, above-mentioned syndeton particularly each hinged place is often rotated, and causes the supported end surface wear; And long-term wearing and tearing accumulation can cause dipper and swing arm normally not to use, and needs to change swing arm and dipper at last, and this has not only brought to the client and has changed the difficulty of swing arm and dipper, but also has improved client's use cost, has caused unnecessary waste.
Summary of the invention
The utility model purpose provides a kind of syndeton of digger operating device, to improve the application life of excavator.
For achieving the above object, the technical solution adopted in the utility model is: a kind of syndeton of digger operating device, described equipment comprises scraper bowl, dipper and swing arm, the two ends of dipper are hinged with scraper bowl, swing arm respectively, the bottom of swing arm and top turntable are hinged, are equipped with wearing plate on the supporting end face between each hinged place of described dipper and scraper bowl, dipper and swing arm, swing arm and top turntable.
Above, the supporting end face between each hinged place of described dipper and scraper bowl, dipper and swing arm, swing arm and top turntable is meant the actual contact part of each hinged place, thereby prevents directly contact friction between the parts; Described wearing plate can be located at one of them parts of hinged place, for example on the bearing surface at dipper two ends wearing plate is set.Wearing plate can be fixed on parts (as the dipper) bearing surface by sunk screw, directly contacts with another parts with the wear-resistant surface that guarantees wearing plate.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, is provided with wearing plate on the supporting end face between each hinged place of the utility model equipment, prevented each parts of equipment, avoided the trouble of replacing equipment parts because of directly contacting the wearing and tearing that produce; After using the wearing and tearing of certain hour wearing plate, as long as change wearing plate, thereby saved a large amount of time, improved efficient, the while has also been saved cost.
2, the utility model is simple in structure, be convenient to produce preparation, and cost is lower, is suitable for applying.
Description of drawings
Fig. 1 is the assembling schematic diagram of the utility model embodiment one;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of wearing plate among the utility model embodiment one.
Wherein: 1, scraper bowl; 2, dipper; 3, wearing plate; 4, sunk screw; 5, counterbore.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one
Shown in Fig. 1~3, a kind of syndeton of digger operating device, described equipment comprises scraper bowl 1, dipper 2 and swing arm, the two ends of dipper are hinged with scraper bowl, swing arm respectively, the bottom of swing arm and top turntable are hinged, are equipped with wearing plate 3 on the supporting end face between each hinged place of described dipper and scraper bowl, dipper and swing arm, swing arm and top turntable.
Shown in Fig. 1~2 is the connection diagram of dipper and scraper bowl, and wherein wearing plate 3 is installed on the bottom of dipper 2, and wearing plate 3 is installed on the dipper by sunk screw 4.
Shown in wearing plate thickness be 4mm, sheet material is No. 45 steel, it is two-sided to carry out hard surfacing and handles, case hardness reaches 50~60HRC, hardening depth is 1mm, surface roughness is 1.6; Have counterbore 5 on the circumference of wearing plate, so that sunk screw is installed.
