Description
Technical field
The utility model belongs to seismoreceiver manufacturing, relates to a kind of cable tension test machine.
Background technology
Cable is mainly used in controlling installation, connection device, transmitting electric power, and is common and indispensable a kind of thing in daily life.Because cable is charged, so it is careful especially to install needs, electric wire is made by drawing, twisting, coated three kinds of techniques complete, and model specification is more complicated, and repeatability is higher.Drawing is in metal-pressed machine, under the effect of external force, make metal be forced through mould, metal cross-sectional area is compressed, and the technology job operation of cross-sectional area shape and size required by obtaining, strand system is the pliability in order to improve electric wire, overall degree, allow the single line of more than 2, according to the direction weave in of regulation, coated is according to the performance requirement different to electric wire, adopt special equipment in the outside of conductor coated different material, after coated good cable, needed water to cool, thus made coated material shaping.In cable production field, need to carry out tensile test to the different batches cable produced, and existing device for testing tensile force can only solely be tested the cable in a certain range of size, the scope of application is little, and structure is stable not, can not measure precisely.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provide a kind of structure simple, manufacture easy, applied widely, tensile test can be carried out to the cable of various sizes model, Stability Analysis of Structures, can measure precisely, and operate cable tension test machine easily.
For achieving the above object, technical solution of the present utility model is: a kind of cable tension test machine, and it comprises bracing frame, be fixed on the fixed head of bracing frame upper end and bottom and base, the lower stationary installation of the cable be fixed on base, electronic crane scale, the upper stationary installation being fixed on the cable of electronic crane scale lower end and take-up device; Take-up device lower end is fixed on the upper end of electronic crane scale, and upper end is fixed on fixed head, its adjustable length between fixed head and electronic crane scale, and it pulls electronic crane scale to move up and down; Upper stationary installation and the lower stationary installation of cable are vertically opposite, the cable after installation and horizontal plane.
Take-up device described above comprises the feed screw nut of band handwheel, the leading screw being fixed on electronic crane scale upper end, thrust ball bearing and bearing seat; Leading screw upper end passes through via hole, feed screw nut on via hole, thrust ball bearing and bearing seat that fixed head has successively, and is threaded in feed screw nut; Bearing seat is fixed on fixed head upper surface, and feed screw nut is connected and fixed by thrust ball bearing and bearing seat.Like this, rotation hand wheel, leading screw just can move up and down along feed screw nut, thus drives electronic crane scale to move up and down, and its Stability Analysis of Structures, makes measurement more accurate.
Upper stationary installation and the lower stationary installation of cable described above comprise holder respectively, be fixed on the horizontally disposed cable clamping seats in holder upper end or lower end two and cable support axle; Cable clamping seats is made up of the clamping seats and gland two opposite faces having cable clamping slot, and gland has the compression matched with clamping slot protruding in the position that the cable clamping slot with clamping seats is corresponding, gland is bolted on clamping seats by plural; The cable clamping seats of upper stationary installation and lower stationary installation and cable support shaft position are just in time contrary, and intersecting vertical is relative.During use, cable lower end is through in the cable clamping slot of the clamping seats of lower stationary installation, after being fixed by gland, after walking around the cable support axle of lower stationary installation, from pull-up vertical between cable clamping seats and cable support axle, the other end, from after walking around the cable support axle of upper stationary installation between the cable clamping seats and cable support axle of upper stationary installation, is through in the cable clamping slot of the clamping seats of stationary installation, is fixed by gland.The upper and lower fixing apparatus structure of this structure is simple, easy stretching cable.
When using the utility model, as long as be fixed in lower stationary installation by cable lower end, upper end is fixed in stationary installation, and take-up device tension electronic crane scale, until cable is broken, the power that electronic crane scale shows is the maximum pull that cable bears.As long as and the length of adjustment take-up device between fixed head and electronic crane scale can adapt to the test of the cable of various length.The utility model structure is simple, manufactures easy, applied widely, can carry out tensile test, Stability Analysis of Structures to the cable of various sizes model, can measure precisely, and operation is convenient.
