The first connecting member 30 and the second connecting member 50 can adopt the structures of hoops, buckles, hooks with locking structures and the like in the prior art. The rope 40 is made of steel wire rope.
The housing 10 is fixedly mounted on the base 110, the housing 10 covers the outside of the winding roller 20, a wire guide hole for the outer end of the rope 40 to pass through is formed in one side of the housing 10 away from the first connecting member 30, and the outer end of the rope 40 passes through the wire guide hole and then is assembled and connected with the second connecting member 50. The state adjustment operation part 72 is disposed outside the housing 10, so that an operator can adjust the operation state of the brake assembly 60 by manipulating the state adjustment operation part 72, thereby achieving convenience in adjusting whether the winding roller 20 is in the locked state or the unlocked state.
When the integrated adjustable locking pulling device is used, the state adjusting component 70 adjusts the operation state of the braking component 60, so that the winding roller 20 is in the following working modes:
in the first operation mode, the rotation state adjustment operation portion 72 makes the first abutting portion 711 abut against and cooperate with the state adjustment abutting portion 622, and at this time, the first locking member 62 is located outside the revolving outer contour of the brake disc 61, that is, the first locking member does not interfere with or obstruct the revolving of the brake disc 61, so that the purpose of paying off the rope 40 by pulling the second connecting member 50 can be achieved, and further, the paying off length of the rope 40 can be adjusted, and in the case of the device having the take-up assembly, after the acting force pulling the second connecting member 50 is removed, the winding roller 20 can achieve the purpose of taking up the rope 40 when the take-up assembly 100 is in operation. For example, if the winding assembly 100 is a coil spring, the automatic winding of the cord 40 can be easily achieved.
In the second operation mode, the state adjustment operation portion 72 is rotated to make the second abutting portion 711 abut against and engage with the state adjustment abutting portion 622, and the locking groove 611 of the first locking element 62 on the brake disc 61 forms a locking engagement, i.e. the rotation of the brake disc 61 is hindered, especially the rotation of the brake disc 61 in the unwinding direction of the winding roller 20 is hindered, so that the winding roller 20 stops unwinding the rope 40, the object is thus achieved that the reel 20 cannot pay out the rope 40 by pulling the second connecting element 50, thereby maintaining the length of the rope 40 already outside the device, in this mode of operation, if the first connecting member 30 is connected to a ground-securing structure (e.g., an earth anchor), after the second connecting member 50 is installed and connected to the pole/tower, it can be used as a temporary stay wire to prevent the pole/tower from falling down.
In the third operation mode, when the apparatus is in the first operation mode and the retracting assembly 100 is capable of automatically retracting the rope 40, if the length of the rope 40 extending out of the apparatus as a cord is long, during the automatic retraction of the rope 40, the acceleration of the retracting roller 20 to the rope 40 may gradually increase to cause the outer end portion of the rope 40 to bounce in a non-directional manner, thereby causing injury to the field worker, and in order to prevent such an event, the retracting speed of the rope 40 may be buffered by the second locking member 63 during the retraction of the rope. The specific implementation can be operated as follows: an operator holds the handle body 91 and the handle 64 by one hand, then pulls the handle 64 to be close to the handle body 91 to enable the limiting clamping portion 631 to move out of the second clamping groove 82, then turns over the handle 90 to rotate around the axis of the winding roller 20 until the limiting clamping portion 631 corresponds to the first clamping groove 81, releases the handle 64, enables the limiting clamping portion 631 to be clamped into the first clamping groove 81 under the action of the second elastic resetting piece 74, and meanwhile, the second locking piece 63 and the locking groove 611 on the brake disc 61 form locking fit to limit the winding roller 20 to rotate towards the direction of the winding rope 40; if the winding roller 20 is to be allowed to rotate in the direction of the winding cord 40, this can be achieved as long as the pulling handle 64 is moved closer to the handle body 91 until the second blocking element 63 is outside the pivoted outer contour of the braking disc 61. Under the working mode, the handle 64 is released timely to enable the handle to be far away from the handle body 91 for resetting, so that the second locking piece 63 is close to the brake disc 61 timely and forms locking fit with the brake disc, the purpose of timely adjusting the winding roller 20 to stop winding can be achieved, and the winding roller 20 can wind the rope 40 more safely and reliably; by pulling the handle 64 at a proper time to make the handle 64 close to the handle body 91, and further to make the second locking member 63 timely separate from the brake disc 61, the winding roller 20 can be allowed to resume the winding of the rope 40.
The fourth working mode is that on the basis that the device is in the second working mode, the locking cooperation of the second locking piece 63 and the brake disc 61 can be utilized, and a structure for preventing the winding roller 20 from continuing to unwind and lock is added, so that the stability, the safety and the reliability of the device when the device is used for temporary wire drawing are improved. The specific operation is as follows: an operator holds the handle body 91 and the handle 64 simultaneously on one hand, then the pulling handle 64 is close to the handle body 91 to make the limiting clamping part 631 shift out of the second clamping groove 82, then the overturning handle 90 rotates around the axle center of the winding roller 20, until the limiting clamping part 631 corresponds to the first clamping groove 81 in position, the handle 64 is loosened, under the action of the second elastic resetting piece 74, the limiting clamping part 631 is clamped into the first clamping groove 81, meanwhile, the second locking piece 63 and the locking groove 611 on the brake disc 61 form locking cooperation, and the winding roller 20 can be limited to rotate towards the direction of the winding rope 40.
A fifth mode of operation is that when the device is not in a rest state as a temporary pull line or needs to be transferred, the transfer of the device can be conveniently realized by the following operations: after rope 40 has completely been taken up to the winding up roller, operating personnel holds handle body 91 and handle 64 simultaneously on one hand, then pulling handle 64 is close to handle body 91 and makes spacing joint portion 631 follow and shift out from first draw-in groove 81, then upset handle 90 rotates around winding up roller 20 axle center, until spacing joint portion 631 corresponds with second draw-in groove 82 position, next unclamp handle 64, under the effect of second elasticity piece 74 that resets, make spacing joint portion 631 card go into second draw-in groove 82, later through mention the handle with the device transfer away can. Of course, in order to prevent the rope 40 from unwinding during the transfer process, the following operations are further performed: since the second locking member 63 is outside the revolving outer contour of the braking disc 61, if the winding assembly 100 is a coil spring capable of maintaining the winding tendency of the rope 40 by the driving roller 20, the device can be transferred by lifting the handle 90; if the furling assembly 100 can not limit the rotation of the winding roller 20 in the unwinding direction in the natural state, the state adjusting operation portion 72 needs to be rotated, so that the second abutting portion 712 and the state adjusting abutting portion 622 abut against and cooperate, and further the rotation of the winding roller 20 in the unwinding direction is limited, and then the device is transferred by lifting the handle 90.
The general application method of the wire drawing device is as follows:
when needs install interim act as go-between to pole, iron tower, earlier with the ground anchor fixed connection on the device of first connecting piece 30 and ground, then, take out the outer end of rope 40 from the device in, tensile to the upper end of pole or iron tower is waited to install the position, after reacing fixed position, fix the outer end of rope 40 and pole, iron tower component or rope 40 self through being similar to staple bolt or metal buckle.
After the outer end of the rope 40 is fixed to the upper end of the electric pole or the iron tower, the operating state of the braking component 60 is adjusted through the state adjusting component 70, and the winding roller 20 on the ground is locked, so that the upper end and the lower end of the rope 40 are both fixed firmly and reliably. The exterior of the wire drawing device can mechanically display the locked state, that is, the position of the operation portion 72 can be adjusted by the state. If the electric pole and the iron tower topple and shift at this moment, the first locking piece 62 and the second locking piece 63 in the braking assembly 60 in the device can play two roles of protection, and the phenomenon of toppling and shifting is slowed down or even stopped.
After work, earlier remove the upper end of rope 40 with pole, iron tower and be connected, will be in the winding up roller on ground again and remove the locking, the rope 40 that will stretch out through the inside coil spring of device is automatic withdraws, owing to inside be equipped with second locking piece 63, handle 64 and the second elasticity piece 74 that can supply manual regulation to prevent to take place because of the too fast risk that causes mechanical injury of rope 40 roll-up.
