Abstract
The utility model relates to rescue equipment, in particular to a miniature portable hydraulic spreader which can be operated in a narrow space. The miniature portable hydraulic spreader is provided with an oil cylinder (20), a spreading clamp body (1) and a spreading block (2). A quick coupling (6) is arranged at the position of an oil inlet of the oil cylinder, a piston reset spring is arranged in the oil cylinder, and the miniature portable hydraulic spreader is characterized in that one end of the spreading block is connected with an oil cylinder piston (14), the other end of the spreading block is arranged in the spreading clamp body, the spreading clamp body is formed by symmetrically combining two spreading arms, and the spreading arms are fixed on a clamp body base (16) through fastening bolts. A tension spring (13) is arranged in the oil cylinder, and is arranged on a tension spring fixing base (15), one end of the tension spring is fixed inside the oil cylinder, and the other end of the tension spring is connected to the spreading clamp body. The miniature portable hydraulic spreader has the advantages of being convenient to use, simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of rescue aid, particularly belongs to a kind of minitype portable hydraulic spreader that can operate in small space.
Background technology
Expander is equipment conventional in rescue operation and engineering, can be used for mobile, lifting barrier, pries open gap and is extended for passage, makes metal structure distortion, tears car body surface steel plate.Conventional expander at present, there is strong expansion, tear and tractive function, can carry out the rescue operation of high load capacity, but this expander in use, strong in function often, act in large environment, and ignored the operator scheme in small space, and sometimes need deep inside, lack simple, light expansion tool.
Utility model content
The purpose of this utility model is to provide a kind of novel micro portable hydraulic spreader, to reach small volume and less weight, simple and practical object.
Micro portable hydraulic spreader provided by the utility model, has oil cylinder, expansion caliper and expansion piece, and the oil-in place of oil cylinder is provided with snap joint, piston reset spring is installed in oil cylinder, it is characterized in that, one end of expansion piece connects oil cylinder piston, and the other end is placed in expansion caliper; Described expansion caliper is formed by two expansion arm Symmetric Composites, and expansion arm is fixed on caliper seat by fastening bolt; In oil cylinder, be provided with extension spring, extension spring is arranged on extension spring holder, and one end of extension spring is fixed on oil cylinder inside, and the other end is connected to expansion caliper.
Micro portable hydraulic spreader provided by the utility model, in use, is connected to the hydraulic oil pipe of manual pump snap joint place of micro portable hydraulic spreader, and then, with manual pump pressurization, oil enters in oil cylinder by oil pipe, promotes piston and stretches out oil cylinder; Be arranged on expansion piece on piston protruding under the promotion of piston, drive the jaw of expansion caliper separately, and then realize extensional motion, there is good effect easy to use, simple in structure, cost is low.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiment of the utility model, wherein,
Fig. 1, the jaw separated position schematic diagram of the utility model expansion caliper;
Fig. 2, the jaw closed schematic diagram of the utility model expansion caliper.
The specific embodiment
As shown in Figure 1, micro portable hydraulic spreader provided by the utility model, has oil cylinder 20, expansion caliper 1 and expansion piece 2, and one end of expansion piece connects oil cylinder piston 14 outboard end, in other end embedded expanding caliper, the stressed promotion expansion of expansion piece caliper opens.Described expansion caliper is formed by the expansion arm Symmetric Composite of two polymorphic structure bodies, and expansion arm afterbody is fixed on caliper seat 16 by fastening bolt, and the oil-in place of oil cylinder is provided with snap joint 6.For guaranteeing in the situation that not using this device, expansion caliper, in closure state, is provided with extension spring 13 in oil cylinder, one end of extension spring is fixed on oil cylinder inside, the other end is connected to expansion caliper, and extension spring is arranged on extension spring holder 15, and extension spring fixed seating is in cylinder tube.For guaranteeing in the situation that not using this device, oil cylinder piston is regained in oil cylinder, and piston reset spring is installed in hydraulic jack, does not do too much explanation therefore belong to prior art.
As shown in Figure 2, the utility model in closing course, by manual pump pressure release, the piston oil cylinder of retracting under the effect of back-moving spring, and then expansion piece retracts, the expansion arm of expansion caliper is withdrawn into original position by under extension spring.
