Abstract
The utility model discloses a strand penetrating device for drawing steel strands. Symmetrical clamping bodies are combined into integration and are composed of an end cover, an elastic sleeve, an anchor cup and clamping pieces, wherein the front half part of the anchor cup is made into a conical shape, the clamping pieces filled into the anchor cup are meshed with the front half part of the anchor cup, the inclination between the clamping pieces and the anchor cup is from 5 to 7 DEG, and springs are arranged on the big ends of the clamping pieces. The utility model is characterized in that central wires of steel strands are clamped by the clamping pieces to provide convenience for penetration and bundle; steel strands can be pushed, conveyed and drawn during penetration and bundle; the looseness and the desquamation of steel strands can be effectively prevented. The utility model has the advantages of high penetrating and bundling efficiency and easy operation.
Description
The utility model relates to a kind of device that is used to draw the steel strand lashing.
The penetrating device of bullet hair style is generally adopted in the steel strand lashing of present domestic suspension cable bridge, this device needs screw thread on the center screw tap of steel strand is linked to each other with the small end of sub warhead again, and the big end of sub warhead and the other end of steel strand are nested together, can only realize lashing by pushing steel strand, because steel strand very easily get loose in pushing the steel strand process, bring the deuce to pay to lashing work.
It is a kind of by clamping steel strand central hair making things convenient for lashing that the purpose of this utility model is to provide, and not only can push but also can draw the lashing device of steel strand when lashing.
Lashing device provided by the utility model fuses symmetrical cramping body by connector, cramping body comprises end cap, elastic cover, anchor cup, intermediate plate, the first half of anchor cup is taper, the intermediate plate that the anchor cup of packing into is interior and the first half of anchor cup match, the gradient α of intermediate plate and anchor cup is 5 °-7 °, at the big end of intermediate plate spring is housed.
Because this lashing device adopts clamping device, therefore it is compared with existing penetrating device and has following advantage: the steel strand lashing is convenient, can clamp steel strand during lashing, can prevent effectively that steel strand from getting loose, in lashing, not only can push steel strand like this, and can also draw steel strand, and make lashing work efficiency height, easy to operate.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1--be structural representation of the present utility model.
As shown in Figure 1, the utility model links into an integrated entity symmetrical cramping body by connector 8, cramping body is made up of end cap 1, elastic cover 2, anchor cup 5, intermediate plate 6, the first half of anchor cup 5 is made taper, the first half of intermediate plate 6 and anchor cup 5 in the anchor cup 2 of packing into matches, intermediate plate 6 is 5 °-7 ° with the gradient α of anchor cup 5, and the big end of intermediate plate 6 is equipped with spring 7, can guarantee that under the effect of spring 7 intermediate plate 6 resets.Again elastic cover 2 is packed into after anchor cup 5 inner clamp pieces 6 small ends, be held tight steel strand and conveniently get loose and withdraw from for making, with the anchor cup 5 of elastic cover 2 opposite positions on have notch 4, clamped steel strand need get loose, the notch 4 promotion elastic covers 2 that insert anchor cup 5 with bottle opener take off intermediate plate 6 to sinciput, withdraw from thereby the steel strand central hair that is clamped by intermediate plate 6 is got loose, the spring 3 that is contained between elastic cover 2 and the anchor cup 6 can make elastic cover 2 reset.During lashing, each penetrates the central hair at steel strand two ends since the cramping body two ends, pass end cap 1, elastic cover 2, anchor cup 5, intermediate plate 6, by intermediate plate 6 the steel strand central hair that passes is clamped, the spring 7 automatic roof pressure intermediate plates 6 that are contained in intermediate plate 6 front ends make it press from both sides steady steel wire.
