Embodiment Construction

[0020] Figure 1, Figure 2, image 3 As shown, the hydraulic slit thruster with double push tail brace and fixed column reset is composed of integrated cylinder 1, double oil channel plate frame 25 and hydraulic reversing. Integrated group cylinder 1 is composed of integrated group cylinder cylinder body 2, fixed column reset plunger 6, push plunger 7, opposite support plunger 8, sealing ring 12, tension spring 14, support plate 15, inserting strip 21, rubber and plastic layer 17 compositions. The central part of the integrated group cylinder body 2 is a reset cylinder body 3 with unequal diameter through holes, the front part on both sides is a push cylinder body 4, and the rear part is a supporting group cylinder body 5, and tension springs are distributed on the supporting group cylinder body Holes 13 and the upper and lower sides are grooves 16 and convex support plates 15 to cooperate to leave a small amount of vertical displacement intervals. After the support plates 15 a...

Abstract

The present invention discloses a twin-tailboom fixed column type reset hydraulic pressure narrow slit thruster which mainly includes an integrated group cylinder I, a double oil channel grillage 25 and a hydrodynamically operated inverting portion, wherein the integrated group cylinder I is composed by a fixed column type reset cylinder 9, a push cylinder 10 and opposite- support group cylinder II; the hydrodynamically operated inverting is composed by a feedback oil cylinder I 23, a feedback oil cylinder II 24 and a hydraulically operated direction control valve. The hydraulic narrow slit thruster described in the invention has unique structure, stable support and locating, powerful impulse force and the grillage structure is suitable for cutting rocks and plate-type powerful digging operations, and the cylinder structure is suitable for well-digging, probe boring and channel digging etc.

Description

(1) Technical field: [0001] The invention belongs to hydraulic actuators, in particular to a hydraulic slit thruster with a double-push tailstay and a fixed column reset type. (two) background technology: [0002] At present, there are few machines and tools for slit propulsion. The latest friction-rolling slit propulsion and paired cylinder hydraulic slit propulsion are limited by low propulsion force, too small friction support surface, unstable work, and complex and fragile pipelines. and cannot be promoted. (3) Contents of the invention: [0003] In order to solve the existing problems in the prior art, the present invention provides a hydraulic slit thruster with a unique structure, stable positioning of the friction struts, and strong thrust. In addition to common technologies such as hydraulic power, overflow valve, and speed control valve, this slit thruster mainly includes three components: integrated cylinder group, double oil passage plate frame, and hydraulic ...
