Abstract
The utility model relates to an outward extending support leg, comprising a handle, a hand ball, a lead screw, a casting, a base, bolts, support legs, an oblique hole and bolt holes; the outward extending support leg is characterized in that the casting is made of casting aluminum; one oblique hole is formed in the front end of the casting and is internally provided with internal threads; the lead screw is connected with the casting by threads; the rear end of the casting extends into the support legs; the casting is fixedly connected with the support legs by the bolts; the included angle between the lower end of the lead screw and the support legs is larger than 90 degrees; the base is arranged at the lower end of the lead screw; the handle is arranged at the upper end of the lead screw and is provided with the hand ball. A mounting and using method comprises the steps of screwing the lead screw into the casting, then mounting the base, connecting and locking the support legs and the casting by the bolts and mounting the handle and the hand ball. When the machine is used, the four support legs are inserted into four angular rectangular pipes of the machine. The casting adopts the casting aluminum material, has better casting performance and higher mechanical performance and is wear-resistant, the lead screw and the ground are arranged in an inclining state and the stability is improved.
Description
Technical field
The utility model relates to construction machinery industry, and a kind of overhanging supporting leg, is applied to play a supportive role in high-lift operation specifically.
Background technique
The supporting leg of like product in prior art, screw mandrel and foundry goods all adopt steel matter to make, and the hardness of steel is larger, and steel and steel friction are worn and torn larger, and screw mandrel is easily broken.And supporting leg is vertical and bottom surface arranges, and bears pressure large, poor stability.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of overhanging supporting leg is provided, the utility model solves the technological scheme that its technical problem adopts: structure of the present utility model comprises handle, handball, screw mandrel, foundry goods, base, bolt, supporting leg, inclined hole, bolt hole, it is characterized in that foundry goods adopts cast aluminium to make, the front end inside of foundry goods is provided with an inclined hole, in inclined hole, be provided with internal thread, screw mandrel is connected with foundry goods by screw thread, on foundry goods, rear side is provided with two bolts hole, the rear end of foundry goods extend in supporting leg, foundry goods is fixedly connected with supporting leg by bolt, between the lower end of screw mandrel and supporting leg, the angle of angle is greater than 90 degree, screw mandrel lower end is provided with base, the upper end of screw mandrel is provided with handle, on handle, be provided with handball.
Install and using method: first screw mandrel is rotated into foundry goods, load onto base, then supporting leg is connected to locking with foundry goods with bolt, be loaded on handle and handball.Four supporting legs are injected to four angular moment pipes of machine when using machine.Rotation handball, height that can four supporting legs of leveling, makes machine keep level, after treating machine level, just can make machine increase.What the casting material in this equipment adopted is that cast aluminium ZL115 makes, and has good castability and higher mechanical property, and the friction of steel and cast aluminium is mainly used in engineering structure part and other parts of large load.Cast aluminium rubs mutually with screw mandrel, and screw mandrel is not easily damaged.This support leg structure is to adopt leg-of-mutton stability principle, and the attachment hole of foundry goods front end is made to angle of inclination, and screw mandrel is rotated into after foundry goods, becomes heeling condition with ground, forms a triangle.Strengthen stability.
The beneficial effects of the utility model are, the utility model foundry goods adopts cast aluminium material, has good castability and higher mechanical property, rub resistance, and screw mandrel becomes heeling condition setting with ground, improved stability.
Accompanying drawing explanation
