Abstract
It the utility model is related to a kind of anti-slip pinch roller of prestress wire strand pulling machine, including 4 pinch rollers driven on strand pulling machine and by strand pulling machine reducing motor, 4 pinch rollers are divided into two groups, each group of pinch roller includes two pinch rollers set one on the other, and two groups of pinch rollers are one in front and one in back set along prestress wire lashing direction；Each pinch roller is provided around the arc groove of wheel face, and groove interior edge pinch roller ring is uniformly arranged multiple salient points.
Description
Technical field
It the utility model is related to prestress wire lashing apparatus field, and in particular to a kind of precast beam prestressed pore passage
The structure of pinch roller used in steel strand pulling machine.
Background technology
, it is necessary to penetrate prestress wire in prestress pipe during precast beam panel construction.Traditional lashing method
It is artificial lashing, but due to the problems such as workload is big, drafting error is big, time-consuming, it is at present to use prestress wire more
Strand pulling machine reduces hand labor intensity to improve operating efficiency.A kind of typical prestress wire strand pulling machine, such as Chinese patent
Application number 201120451750.2, entitled " prestress wire strand pulling machine " patent disclosed in structure, it includes two
Driving wheel, driving wheel top set fastening wheel, and prestress wire passes through between driving wheel and fastening wheel, is rotated by driving wheel
Frictional force drives prestress wire movement, prestress wire is penetrated into prestress pipe.Current prestressing force strand pulling machine
After used a period of time, more serious abrasion occurs in driving wheel, causes prestress wire skidding, it is necessary to adjust
Fastening wheel is to increase the frictional force between driving wheel and steel strand wires；As frequency of use increases, skidding be continuously increased, it is necessary to
Constantly adjustment pinch roller, or driving wheel is changed, therefore work efficiency is have impact on, add construction cost.
The content of the invention
The purpose of this utility model is to be directed to skidding caused by current prestress wire strand pulling machine use, carried
For a kind of prestress wire strand pulling machine anti-slip pinch roller, to be skidded when solving the problems, such as strand pulling machine work, work efficiency is improved,
Reduce cost.
The technical solution of the utility model is as follows：
A kind of anti-slip pinch roller of prestress wire strand pulling machine, including on strand pulling machine and by strand pulling machine deceleration electricity
4 pinch rollers of machine driving, it is characterised in that：4 pinch rollers are divided into two groups, and each group of pinch roller includes two pressures set one on the other
Wheel, two groups of pinch rollers are one in front and one in back set along prestress wire lashing direction；Each pinch roller is provided around the arc groove of wheel face,
Groove interior edge pinch roller ring is uniformly arranged multiple salient points.
The utility model has the advantages of simple in construction, cost is low, by setting anti-skidding salient point on pinch roller, increases pinch roller
With steel strand wires contact point, reaching prevents slipping effect, extends strand pulling machine service life, improves efficiency of construction.
Brief description of the drawings
Fig. 1 is structural representation of the pinch roller of the present utility model along parallel pinch roller axial direction；
Fig. 2 is structural representation of the pinch roller of the present utility model along vertical pinch roller axial direction.
Fig. 3 is a kind of use state side view of the present utility model；
Fig. 4 is a kind of use state front view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model includes being arranged on 4 driven on strand pulling machine 1 and by strand pulling machine reducing motor
Individual 2,4 pinch rollers 2 of pinch roller are divided to for two groups, and each group of pinch roller includes two pinch rollers set one on the other, and two groups of pinch rollers are answered along pre-
Power steel stranded wire penetrating adapter direction is one in front and one in back set；Each pinch roller 2 is provided around the arc groove 3 of wheel face, the interior edge pinch roller ring of groove 3
To being uniformly arranged multiple salient points 4.
As shown in Fig. 3 Fig. 4,4 pinch rollers are arranged on strand pulling machine, and pinch roller is driven by strand pulling machine reducing motor to be rotated.Will be pre-
Prestress steel strand 5 by two pinch rollers upper lower pressure wheel 2 space pass through, and compressed by upper lower pressure wheel, strand pulling machine reducing motor
Lower pressure wheel rotates round about respectively in driving, is made by the frictional force between the salient point 4 and prestress wire 5 on pinch roller 2
Prestress wire moves into the prestress pipe 7 of precast plate girder 6, realizes prestress wire lashing.
The utility model connects due to being provided with salient point, salient point on pinch roller with prestress wire perficial helical connected in star
Touch, increase frictional force, reduce prestress wire skidding during lashing, so as to improve operating efficiency, also extend
The service life of pinch roller.
