Abstract
The invention belongs to the technical field of flexible pull rod prestress tensioning, and particularly relates to a striding type flexible pull rod hydraulic tensioning device. The striding type flexible pull rod hydraulic tensioning device is mainly composed of a high-strength pull rod, a front kidney-shaped notched plate, a rear kidney-shaped notched plate, a hydraulic jack, a manual hydraulic pump and the like. The striding type flexible pull rod hydraulic tensioning device can be mounted on two flexible pull rods which are connected through turn buckles, and can tightly abut against the flexible pull rods through a front nut and a rear nut; under the tensioning action of the hydraulic jack, the turn buckles are tightly screwed while the high-strength pull rod is tightened, and therefore the purpose of straining the flexible pull rods for tensioning is achieved. The striding type flexible pull rod hydraulic tensioning device can well solve the problems that a jack used for an existing hydraulic tensioning device is complex in structure, large in amount of steel used at joints, inconvenient to construct and the like, and also can solve the problem that the application of prestress of the flexible pull rods is inaccurate. As a result, delivery-receiving acceptance of a flexible support is strict, and a large amount of steel is saved.
Description
Technical field
The invention belongs to flexible draw bar prestressing stretching technique field, be specifically related to a kind of great-leap-forward flexible draw bar hydraulic stretching device.
Background technology
Flexible draw bar generally is comprised of parts such as cylindrical rod piece, regulating sleeve, locknut and two ends Earring connectors.Due to its restriction that is not subject to slenderness ratio, in tall and slender structure, front face area is little, saves material, so be used widely.Apply prestressed flexible draw bar and not only significantly reduce the head tower steel quantity consumption, and can not cause the reduction of the rigidity of structure.Usually adopt at present hydraulic stretching device to apply prestressing force to flexible draw bar, but there is following defect in existing hydraulic stretching device: its jack is enclosed within on the same straight line of flexible draw bar usually, directly flexible draw bar is carried out to stretch-draw, tend to disturb mutually with the rod end gusset plate, so need on flexible draw bar, add adapter, complex structure, the node steel using amount is large; Volume is larger, and the construction transportation is installed inconvenient.Flexible draw bar can also be connected by flower basket bolt, adopt the handmade rotary flower basket bolt to add pretension, this way exists pretension inaccurate, the affected defect of quality.
Summary of the invention
The above-mentioned defect existed in order to overcome the prior art field, the object of the invention is to, and provides that a kind of volume is little, simple structure, node steel using amount are little, apply prestressing force great-leap-forward flexible draw bar hydraulic stretching device accurately.
Great-leap-forward flexible draw bar hydraulic stretching device provided by the invention, it comprises high-strength pull bar, Attacking Midfielder's v notch v plate, low back v notch v plate, high-strength pull-rod nut and hydraulic jack, described high-strength pull bar one end is fixedly connected with hydraulic jack through Attacking Midfielder's v notch v plate, and the other end is fixedly connected with high-strength pull-rod nut through low back v notch v plate; Described high-strength pull bar, hydraulic jack, high-strength pull-rod nut have respectively two, and described two high-strength pull bars are in same level; Described each high-strength pull bar includes two strength round steels and a high strength steel pipe, and described two strength round steels are set in respectively the two ends of high strength steel pipe, and adopts fillet weld weld all around or plug welding to reinforce; It also comprises hydraulic hand-pump, and described hydraulic hand-pump is connected with hydraulic jack by petroleum pipeline; Described piston rod of hydraulic jack end is provided with stop nut.
Great-leap-forward flexible draw bar hydraulic stretching device provided by the invention, its beneficial effect is: jack is enclosed within on high-strength pull bar, with flexible draw bar, not on same straight line, not limited by the flexible draw bar end node, reduces structural acessory, saves steel using amount; Two hydraulic jack are arranged, effectively improved the stretching force of tensioner, promoted the convenience of construction and installation simultaneously; The employing Materials with High Strength is made, and conducts oneself with dignity lighter; Solved the inaccurate problem of current flexible draw bar prestressing force, made flexible support delivery receiving acceptance severization; Carry out two times tensioning for the flexible draw bar of having installed also very convenient, and can detect by the oil pressure gauge on hydraulic hand-pump the value of thrust in stretching process, in single storey industry workshop, tower mast (comprising power tower) and other buildings, structure, promotional value also be arranged.
