In order to solve the technical problems, the technical scheme of the invention is as follows:

the utility model provides a novel self-balancing load formula pressurized cylinder, includes:

the box body comprises a round hole, a cement paste hole and a water inlet hole, the round hole is arranged in the center of the box body, an oil inlet hole is formed in the round hole, the cement paste hole is respectively arranged at the left end and the right end of the round hole, and the water inlet hole is respectively arranged at the front end and the rear end of the round hole;

the piston mechanisms are respectively arranged at four top corners of the bottom of the box body and comprise cylinder head oil seals and cylinder heads which are arranged from bottom to top, and the cylinder heads are respectively connected with the round holes through oil inlet holes;

and the top plate mechanism is arranged at the bottom of the box body and comprises a top plate and a steel shaft which are arranged from bottom to top.

Further, the diameter of the steel shaft is equal to the diameter of the cylinder head.

Further, the inlet port is from inside to outside diameter grow gradually, and the cross-section presents isosceles trapezoid, just the inlet port is only one, the inlet port is including locating the oil inlet way in the outside, the inlet port passes through the oil inlet way and is connected with the cylinder head respectively.

Further, the top plate moves in the cylinder head in the vertical direction through a steel shaft.

Further, the top plate is limited by a cylinder head oil seal.

Further, the diameter of the round hole is 30% of the diameter of the box body.

The invention has the beneficial effects that:

according to the self-balancing load-type supercharging oil cylinder, the top plate moves in the cylinder head in the vertical direction through the steel shaft, the diameter of the top plate gradually increases from inside to outside through the oil inlet hole, the section of the top plate is in an isosceles trapezoid shape, the diameter of the steel shaft is equal to that of the cylinder head, and the like, so that the novel self-balancing load-type supercharging oil cylinder is compact in structure, accurate in jacking and simple and convenient to use.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

According to the description of fig. 1-4:

the utility model provides a novel self-balancing load formula pressurized cylinder, includes:

the box body 1 comprises a round hole 11, a cement paste hole 13 and a water inlet hole 12, wherein the round hole 11 is arranged at the center of the box body 1, an oil inlet hole 111 is formed in the round hole 11, the cement paste hole 13 is respectively arranged at the left end and the right end of the round hole 11, and the water inlet hole 12 is respectively arranged at the front end and the rear end of the round hole 11;

the piston mechanisms 2 are respectively arranged at four top corners at the bottom of the box body 1 and comprise cylinder head oil seals 21 and cylinder heads 22 arranged from bottom to top, and the cylinder heads 22 are respectively connected with the round holes 11 through oil inlet holes 111;

the top plate mechanism 3 is arranged at the bottom of the box body 1 and comprises a top plate 31 and a steel shaft 32 which are arranged from bottom to top.

The diameter of the steel shaft 32 is equal to the diameter of the cylinder head 22.

Because the diameter of the oil inlet hole 111 gradually increases from inside to outside, the cross section of the oil inlet hole is in an isosceles trapezoid shape, only one oil inlet hole is provided, the oil inlet hole 111 comprises the oil inlet channel 1111 arranged on the outer side, and the oil inlet hole 111 is respectively connected with the cylinder head through the oil inlet channel 1111, when a user uses the oil delivery pipe of the oil delivery pipe, the oil delivery pipe of the oil delivery pipe, the oil delivery pipe of the oil delivery pipe, the oil delivery pipe of the oil delivery pipe, and the oil delivery pipe of the oil delivery pipe, the oil of the oil delivery pipe of the oil delivery, thereby solving the phenomena of cylinder pulling and shaft pulling.

The diameter of the circular hole 11 is 30% of the diameter of the box body 1.

The top plate 31 is vertically moved in the cylinder head 22 by a steel shaft 32.

Because the top plate 31 is limited by the cylinder head oil seal 21, when a user uses the invention, the top plate 31 can be prevented from moving upwards too much by the limitation when being driven upwards, the inner space of the cylinder head 22 is filled, and the top plate 31 cannot be lifted downwards when cylinder oil is input.

When a user uses the invention, firstly the invention and an external pile foundation reinforcement cage are welded, then an oil delivery pipe, a water inlet pipe and a cement paste pipe are respectively placed in the round hole 11, the water inlet hole 12 and the cement paste hole 13, then concrete piles can be respectively formed by pouring through the pouring of cement paste, when an oil pump outside the oil delivery pipe outputs or pumps back cylinder oil, the top plate 31 is lifted or descended along with the oil pressure of the cylinder oil in the cylinder head 22, and because the piston mechanism 2 is arranged in four corners, the phenomenon that the position is lifted or descended and the position is inclined can be avoided when the top plate 31 is lifted or descended.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
