Abstract
The utility model provides a work limiting mechanism of a loader bucket. The mechanism mainly comprises a bucket retracting limiting block and an unloading limiting block. The bucket retracting limiting block is welded to the upper side of a movable arm supporting plate at the rear end of a bucket assembly, and the unloading limiting block is welded to the lower side of the movable arm supporting plate at the rear end of the bucket assembly. The bucket retracting limiting block and the unloading limiting block are respectively provided with adjusting pad pressing plates, multiple adjusting pads are arranged between the adjusting pad pressing plates and the bucket retracting limiting block or between the adjusting pad pressing plates and the unloading limiting block, and the adjusting pad pressing plates and the adjusting pads are fixed to the bucket retracting limiting block or the unloading limiting block through fixing bolts. When a bucket limiting block is welded, people only need to weld the bucket limiting block after a bucket is loaded and do not need to connect the bucket to a work device. Adjustment of the limiting thickness through the adjusting pad effectively reduce production blindness, and meanwhile unloading and bucket retracting angles of the bucket are guaranteed, so that the limiting block mechanism guarantees technical parameters of work of the bucket and overcomes the defects of traditional work.
Description
Technical field
The utility model belongs to technical field of engineering machinery, is specifically related to a kind of loading shovel work position-limit mechanism.
Background technology
Wheel loader is a kind ofly to take handling bulk material and be main earth moving machinery, can be widely used in the places such as the engineerings such as highway, railway, harbour, harbour, colliery, mine, goods yard, water conservancy, national defence and urban construction, configure multiple equipment and can realize the functions such as handling, excavation, fragmentation, a tractor serves several purposes.At present loading shovel receive bucket and discharging spacing generally adopt on assembly line, assembled join weldering after equipment can not mode position limiting structure, this weldering scraper bowl limited block mode of joining is used for many years on loader, but there is a lot of drawbacks, the one, while joining weldering scraper bowl discharging limited block, scraper bowl need to be risen to extreme higher position, make scraper bowl reach discharging angle 45 degree, welding is easy to cause cylinder piston rod to get ready, damage oil cylinder, and join weldering scraper bowl discharging limited block and belong to aerial work, work abnormally dangerous, have potential safety hazard, easily cause security incident; The 2nd, to join scraper bowl weldering limited block and can waste a lot of time, production efficiency is low, causes scraper bowl and movable arm welding splash thereof after having welded, and for removing these splashes, also will re-start and spray paint, and cost of production is increased; The 3rd, due to the mismachining tolerance of parts, causing scraper bowl limited block and swing arm contact position to form line contacts, whether the welding of scraper bowl limited block accurately directly has influence on the application life of operating efficiency and the parts of loader, while is due to the existence of mismachining tolerance, produce and need the different limited block of the various thickness of preparation to meet Production requirement, take a lot of work, time-consuming, to stock control, bring suitable trouble.
Summary of the invention
The utility model provides a kind of loading shovel work position-limit mechanism, to solve the problems of the technologies described above.
The utility model mainly forms by receiving bucket limited block and discharging limited block, and solving the technical scheme that its problem adopts is to receive bucket limited block in the welding of scraper bowl assembly rear end swing arm gripper shoe upside, at scraper bowl assembly rear end swing arm gripper shoe downside welding discharging limited block; Receive on bucket limited block and discharging limited block adjusting pad pressing plate is set respectively, between adjusting pad pressing plate and receipts bucket limited block or discharging limited block, several adjusting pads are set, adjusting pad pressing plate and adjusting pad are fixed on and are received on bucket limited block or discharging limited block by set bolt.
Preferably, described adjusting pad thickness of compressive plate is 16-18mm, and the thickness of each adjusting pad is 1-5mm.
During the utility model weldering scraper bowl limited block, only need after scraper bowl has taken up, just can weld, not need scraper bowl to be connected on equipment; And adjusting pad has also effectively been shared the blindness of producing to the adjustment of spacing thickness, also guaranteed the discharging of scraper bowl simultaneously and received bucket angle, so this utility model limit block mechanism has guaranteed the technical data of scraper bowl work, require and avoid traditional work drawback.
The utility model is very convenient, saves time, and production efficiency is very high, and labour intensity is little; Owing to adopting directly fixing weldering tire of scraper bowl tie point, reduced the component processing accumulation of error, the welding of scraper bowl limited block is more accurate, and when realizing scraper bowl limited block and contact with swing arm, face contacts, and guarantees limit effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model scraper bowl limited block welding schematic diagram;
In figure, 1 scraper bowl assembly, 2 set bolts, 3 swing arms, 4 adjusting pad pressing plates, 5 adjusting pads, 6 discharging limited blocks, 7 are received locating shaft on bucket limited block, 8,9 scraper bowl limited block weldering tires, 10 times locating shafts.
The specific embodiment
As shown in the figure, when receiving bucket limited block 7(work, the 1 rear end swing arm 3 gripper shoe upside welding of scraper bowl assembly contact with swing arm front edge of board upside), when the 1 rear end swing arm 3 gripper shoe downside welding discharging limited block 6(work of scraper bowl assembly, contact with swing arm front edge of board downside), particular location and angle are guaranteed by scraper bowl limited block weldering tire 9; Receive on bucket limited block 7 and discharging limited block 6 adjusting pad pressing plate 4 is set respectively, between adjusting pad pressing plate 4 and receipts bucket limited block 7 or discharging limited block 6, several adjusting pads 5 are set, adjusting pad pressing plate 4 and adjusting pad 5 are fixed on and are received on bucket limited block 7 or discharging limited block 6 by set bolt 2; Adjusting pad pressing plate 4 thickness are 16-18mm, and the thickness of each adjusting pad 5 is 1-5mm.
During welding, first using locating shaft 8 and lower locating shaft 10 is fixed on scraper bowl limited block weldering tire 9 on scraper bowl assembly 1 by two connecting holes, then by struggle against A, the B face of limited block 7 or discharging limited block 6 and scraper bowl limited block weldering tire 9 of receipts, determine that position and the angle of receiving bucket limited block 7 or discharging limited block 6 (are limited and received struggle against limited block 7 or discharging limited block 6 and swing arm 3 contact positions by A face respectively, by B face, limited the angle of receiving bucket limited block 7 or discharging limited block 6), receipts bucket limited block 7 and discharging limited block 6 are welded on to (see figure 2) on scraper bowl assembly 1.After having welded, scraper bowl limited block weldering tire 9 is taken off, scraper bowl assembly 1 and complete machine are connected, adjust scraper bowl assembly 1 to respective angles (receive bucket and discharging and be 45 degree), according to the gap between scraper bowl assembly 1 and swing arm 3, increase corresponding adjusting pad, concrete scheme is: directly contact with swing arm for thickness be the adjusting pad pressing plate 4 of 16-18mm, prevent from receiving the too early wearing and tearing of bucket limited block 7 and discharging limited block 6, between adjusting pad pressing plate 4 and receipts bucket limited block 7 or discharging limited block 6, increase several adjusting pads 5, each adjusting pad 5 thickness is 1mm, 2mm, 3mm or 5mm, the quantity of required adjusting pad 5 is as the criterion to reach the angle of technical requirements, finally with set bolt 2, fix.
