Abstract
The utility model discloses a force (applied to anchor cable)-measuring device whose cylinder body and piston form two stepping cylindrical sealing faces with different diameters. High pressure oil is filled to push the piston connected with the anchor head of a cable in order to achieve the goal of measuring and adjusting the cable force of the cable.
Description
The utility model is a kind of isolated plant of measuring cable tension.
Frequency measurement method, Strain Method and hydraulic jack method are more generally adopted in the measurement of cable-stayed bridge cable tension at present, and several method all has weak point.Though the frequency measurement method is simple and easy to do, tension force changes with the cable rigid condition is different with the relation of frequency, has certain error; Though Strain Method is intuitive and reliable, the element of measuring distortion is difficult to fixing and long preservation on cable; Hydraulic jack method numerical value is reliable, but volume is big, heavy, uses very inconveniently, if bridge builds up, does not have loop wheel machine, and the force-bearing situation that measure cable is just more difficult.
The purpose of this utility model is to provide a kind of measurement precision height directly perceived, and mounting or dismounting are convenient, and the cable device for measuring force that can adjust while surveying cable.
The related cable device for measuring force of the utility model is made up of the cylinder body (5) and the piston (4) of the garden cylindricality mating surface that has two diameter not wait, and packoff (3) is arranged on two mating surfaces, can form with O shape rubber seal and polytetrafluoroethylene ring washer.Oil supply hole (6) and the hydraulic quick coupler jack (7) that is used for being connected with oil pipe are arranged on the cylinder body, and the shoulder plane between the cylinder of the not isometrical garden of oil supply hole and piston communicates.Cylinder body one end can have safety screen (2) and Stroke Control and telltale (1), the promising adjustment anchor head of other end nut (8) and the opening that is provided with.The mesopore screw thread is arranged on the piston, can with the thread connection of cable anchor head.
When the novel cable device for measuring force uses, by the thread connection of piston by mesopore screw thread and cable anchor head, connect the high-pressure oil pump oil pipe with hydraulic quick coupler, oil pump is gone into cylinder body form an annular oil cavity, promote piston and drive cable slightly, record is oil pressure at this moment, and exerting oneself by oil pressure and piston that prior demarcation is good, (linear relationship chart of cable tension is promptly known cable tension.When doing the Suo Li adjustment, only need increase throw of poston slightly, the cable elongation is increased to some extent, the anchoring nut that drives on the anchor head is thrown off beam body support plate, from the opening part setting nut, to reach the purpose of adjusting cable force.This device is just just in running order when feeding hydraulic oil, and in non-Measuring Time, its inner member is in the non-stress state, and the life-span is long.Because of adopting the national standard seal element, versatility is good again.
Accompanying drawing 1 is a novel cable device for measuring force structural principle diagrammatic sketch.(1) Stroke Control and telltale among the figure, (2) safety screen, (3) packoff, (4) piston, (5) cylinder body, (6) oil supply hole, (7) hydraulic quick coupler jack, (8) anchor head nut.Accompanying drawing 2 is that the novel cable device for measuring force is at the installation site of Liang Tishang diagrammatic sketch.(9) cable among the figure, (10) beam body, (11) anchor head, (12) cable device for measuring force, (13) beam body support plate.
The utility model can be equipped with different pressure caps at piston when making, during less than the piston intermediate pore size, then by the internal thread on the pressure cap and anchor head threaded engagement, make device have versatility with the anchor head size of convenient cable.
Claims (2)
1, a kind of cable device for measuring force that constitutes by cylinder body, piston, the mating surface that it is characterized in that cylinder body and piston is the garden cylindroid that two diameter do not wait, on the two garden cylinders packoff is arranged, oil pipe hydraulic quick coupler jack and oil supply hole are arranged on the cylinder body, shoulder plane between the cylinder of the not isometrical garden of oil supply hole and piston communicates, and the mesopore screw thread is arranged on the piston.
2, cable device for measuring force according to claim 1 is characterized in that packoff is made up of O shape rubber seal and polytetrafluoroethylene ring washer.
