Abstract
The utility model relates to a large-tonnage equal-thrust engineering hydraulic jack, and the hydraulic jack comprises at least three cylinder bodies, a hanging piece, a main oil way, a front cover, and a rear cover. The three cylinder bodies are a cylinder body 1, a cylinder body 2, and a cylinder body 3. The cylinder body 1 is provided with pistons of the cylinder body 1, and the pistons of the cylinder body 1 are connected to two ends of the cylinder body 1 in a screw joint manner. The cylinder body 2 is provided with pistons of the cylinder body 2, and the pistons of the cylinder body 2 are connected to two ends of the cylinder body 2 in a screw joint manner. The cylinder body 3 is provided with pistons of the cylinder body 3, and the pistons of the cylinder body 3 are connected to two ends of the cylinder body 3 in a screw joint manner. The hydraulic jack provided by the utility model employs at least three cylinder bodies, achieves the total travel: the contour length greater than 2: 1, is suitable for the engineering pipe drawing in narrow construction places and the pipe-drawing length, reduces the situations of frequent reciprocating movement of a push rod, improves the work efficiency, and reduces the power consumption and wear.
Description
Technical field
The utility model belongs to the thrust engineering hydraulic jacks such as large-tonnage engineering hydraulic jack technical field, especially a kind of large-tonnage.
Background technology
At present, engineering tube drawing workyard is narrow, and tube drawing length is large, and single-stage large-tonnage push rod is placed wastes time and energy, and sometimes can not let go at all.The single-stage large-tonnage jack of prior art, total kilometrage: clearance length < 2: 1, needs that push rod is frequent back and forth, the jig that moves around, and efficiency is low, power consumption is many, fragile; Along with scientific and technological progress, need to develop a kind of jack that dwindles clearance length stroke extension.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the thrust engineering hydraulic jacks such as a kind of large-tonnage are provided, its total kilometrage: clearance length > 2: 1, and efficiency is high, energy-conserving and environment-protective, reduction wearing and tearing, increases the service life.
The utility model solves its technical matters and takes following technical scheme to realize:
The thrust engineering hydraulic jacks such as a kind of large-tonnage, comprise at least three cylinder bodies, lifting suspension member, working connection, protecgulum and bonnet, described three cylinder bodies are a cylinder body, two cylinder bodies and three cylinder bodies, a described cylinder body is provided with a cylinder piston, and a cylinder piston is bolted in the two ends of a cylinder body, described two cylinder bodies are provided with two cylinder piston, and two cylinder piston is bolted in the two ends of two cylinder bodies, described three cylinder bodies are provided with three cylinder pistons, and three cylinder pistons are bolted in the two ends of three cylinder bodies.
And described protecgulum comprises a cylinder front cover, two cylinder front covers and three cylinder front covers.
And described bonnet comprises a cylinder body bonnet and two cylinder body bonnets.
Advantage of the present utility model and good effect are:
1, the utility model adopts at least three cylinder bodies, reached total kilometrage: clearance length > 2: 1, better narrow workyard and the tube drawing length that adapts to engineering tube drawing, the situation that has reduced the back and forth frequent and jig that moves around of push rod, has improved work efficiency, has reduced power consumption, has reduced wearing and tearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
