Abstract
The utility model discloses a double hook line tightening device, comprising hook screw rods, a nut, a sleeve cylinder, safety pins, a ratchet wheel, a handgrip assembly, and locking plates. The end part of each hook screw rod is provided with a safety pin, preventing the hook screw rod from disengaging from the nut in screwing-out; the head part of each hook screw rod is provided with a locking plate, preventing propping of steel strands or wire ropes from the hooks in hitching. the two hook screw rods are left and right T-shaped screw thread screw rods, and are respectively screwed in the two left and right T-shaped screw thread nuts, the two left and right T-shaped screw thread nuts are respectively screwed at the outer walls at the two sides of the sleeve cylinder via triangular screw threads. The ratchet wheel is installed at the middle part of the cylinder sleeve, the external of the ratchet wheel is provided with the handgrip assembly, the internal of the handgrip assembly is provided with a ratchet pawl capable of changing direction, turning of a handle can drive the sleeve cylinder to rotate via the ratchet wheel, change of engagement positions of the pawl and the ratchet wheel can make the ratchet wheel in a forward rotation or backward rotation, and make the hook screw rods screw in or out of the sleeve cylinder, thereby realizing purpose of tensioning or loosening. The line tightening device in the utility model is advantaged by safety and reliable use, and convenient operation.
Description
Technical field
The utility model belongs to the small sheet clamping tool, is specifically related to a kind of double hook turnbuckle.
Background technology
Tensioning when turnbuckle is mainly used in fixed object in department's work progress such as electric power, telecommunications, railway, building; Distance and pulling force according to required tensioning vary in size, and its form mainly contains: ratchet roll type, double hook are telescopic, chain block, screw-button (turnbuckle) etc.Wherein use comparatively extensive with the telescopic turnbuckle of double hook; It mainly is made up of sleeve, hook-type screw mandrel and handgrip, and the sleeve two ends are furnished with the different T shape screw thread screw of rotation direction, and the thread rotary orientation of two hook-type screw mandrels is also different; Be combined on respectively in two screws; When pulling handgrip and drive sleeve and rotate forward or backwards, two hook-type screw mandrels will shrink or stretch out in opposite directions, the purpose that reaches tensioning or unclamp.Not enough below the telescopic turnbuckle of existing double hook exists: as to treat generally that 1. the steel strand wires of tensioning or steel wire rope all have elasticity; Be easy to ejected after beginning to hang the turnbuckle gib head; People's operation is relatively more difficult, needs three people to operate simultaneously usually and could accomplish tensioning work.2. owing to can't see behind the hook-type screw mandrel screw-in sleeve, might throw off screw or too short when outwards screwing out fully, cause certain potential safety hazard because of length of thread engagement.3. be the turnbuckle of the band ratchet mechanism of ZL200520100795.X like the patent No., its structure is huge, requirement on machining accuracy is high, manufacturing is difficult.Cause the reason of the above-mentioned deficiency of this turnbuckle to be: two nuts in sleeve two ends are through being threaded in sleeve lining on the one hand; Simultaneously also will with guy hook through being threaded; Under the certain situation of live load; Be guy hook diameter one regularly, its nut is connected sleeve lining and is connected the required sleeve diameter of sleeve outer wall than nut and must increases.This turnbuckle is set to a hollow guy hook and a solid guy hook on the other hand, and when double hook was reduced to certain position, solid guy hook was flexible in hollow guy hook, and this also requires to increase sleeve diameter.This makes that all the physical dimensions such as ratchet, handle that are enclosed within its outside also must corresponding increase, this turnbuckle sleeve diameter=solid guy hook screw mandrel diameter+reasonable clearance+hollow guy hook wall thickness+be connected wall thickness of sleeve lining place nut.
Summary of the invention
The purpose of the utility model is to overcome the deficiency and the defective of prior art, proposes a kind of simple in structure, easily manufactured, safe and reliable double hook turnbuckle.
The technical scheme that realizes above-mentioned purpose is: the double hook turnbuckle, it comprises two hook-type screw mandrels, two screws, a sleeve, a ratchet, a handle assembly, two safety pins and two locking plates.Said two hook-type screw mandrels are respectively left and right sides T shape threaded screw rod; Two screws are respectively left and right sides T shape screw thread screw; The sleeve middle part is provided with ratchet; Two left and right sides T shape screw thread hook-type screw mandrels screw respectively in two left and right sides T shape screw thread screws, and two screws screw the wall outside the sleeve two ends respectively through angular thread, and handle assembly is installed on the ratchet.
The effect of the utility model is: the double hook turnbuckle according to such scheme is made, can change the ratchet direction according to instructions for use, and pull handgrip and drive the sleeve rotation through ratchet, make the hook-type screw mandrel screw in or screw out sleeve simultaneously in opposite directions.Can not deviate from screw when the hook-type screw mandrel screws out, be tensioned steel strand wires or steel wire rope can not eject the gib head of hook-type screw mandrel yet, and be safe and reliable, easy to use.The utility model sleeve diameter=screw mandrel diameter+reasonable clearance, simple in structure, easy to process.
Description of drawings
Fig. 1 is the overall structure sketch map of an embodiment of the utility model double hook turnbuckle.
Fig. 2 is the enlarged drawing at Figure 1A place.
Among the figure: 1. hook-type screw mandrel, 2. screw, 3. sleeve, 4. safety pin, 5. rivet, 6. handle assembly, 7. ratchet, 8. screw, 9. bearing pin, 10. locking plate, 11. springs.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, the utility model double hook turnbuckle includes two hook-type screw mandrels 1, two screws 2, sleeve 3, two safety pins 4, two rivets 5, handle assembly 6, ratchet 7 and two screws 8.Be processed with left and right sides T shape screw thread on two hook-type screw mandrels 1 respectively; And screw respectively in two screws 2 that are processed with left and right sides T shape screw thread; Screwing back hook-type screw mandrel end riveted joint has safety pin 4, can not throw off screw 2 when screwing out with assurance hook-type screw mandrel 1, and guarantee to have certain screwing length.Two screws 2 screw the outer wall at the two ends of sleeve 3 respectively through angular thread, and are fixed on the sleeve 3 through screw 8.Ratchet 7 is riveted on the middle part of sleeve 3 through rivet 5, and the handle assembly 6 with ratchet capable of reversing is housed on the ratchet 7.Pull handle assembly 6 during work, drive sleeve 3 through ratchet 7 and rotate forward or backwards with screw 2, two hook-type screw mandrels in two ends 1 will screw in or screw out sleeve 3, the purpose that reaches tensioning or unclamp simultaneously in opposite directions.
As shown in Figure 2, hook-type screw mandrel 1 is provided with bearing pin 9, locking plate 10 and spring 11.Locking plate 10 and spring 11 are fixed on the gib head portion of hook-type screw mandrel 1 through bearing pin 9, and locking plate 10 can rotate around bearing pin 9 with spring 11.Depressing locking plate 10 can hang over steel strand wires or steel wire rope in the gib head of hook-type screw mandrel 1; Hang back locking plate 10 rebound reset under the elastic force effect of spring 11; And be stuck in the gib head place of hook-type screw mandrel 1, hung steel strand wires or steel wire rope can't eject from the gib head of hook-type screw mandrel 1.
