Detailed Description
As shown in fig. 1 and 2, an automatic wire-setting tensioning device for a power pole wire comprises a bottom plate 10, wherein support plates 20 are fixedly connected to the left and right sides of the top of the bottom plate 10, rotatable rotating rods 21 are rotatably connected to opposite sides of the two support plates 20, a winding roller 22 is mounted on the rotating rods 21, and a wire body 23 is fixedly wound on the winding roller 22.
Specifically, a first connecting plate 24 is fixedly connected to the left side of the support plate 20 on the left side, a motor 25 is fixedly connected to the top of the first connecting plate 24, and an output end of the motor 25 is fixedly connected to the left side of the rotating rod 21. When the wire body 23 is installed behind the wire pole and needs tensioning, the motor 25 is started through an external power supply, and the output end of the motor 25 drives the winding roller 22 to rotate, so that the wire body 23 is wound on the winding roller 22. Thereby putting the wire in tension.
In the winding process of the wire body 23, the wire body 23 cannot be guided when being wound, so that the wire body 23 is wound at one position of the winding roller 22, and the winding roller 22 is excessively thick at one position, thereby affecting the storage of the wire body 23 on the winding roller 22. A guide mechanism at the time of winding the electric wire body 23 is thus proposed.
Referring to fig. 1, 2 and 3, a fixed plate 30 is fixedly connected to the top of the bottom plate 10, the fixed plate 30 is located in front of the supporting plate 20, vertical plates 31 are fixedly connected to the left and right ends of the top of the fixed plate 30, rotatable reciprocating screw rods 32 are rotatably connected to opposite sides of the two vertical plates 31, and a moving block 33 is connected to the reciprocating screw rods 32 in a threaded manner; the opposite sides of the two vertical plates 31 are fixedly connected with guide rods 34, and the guide rods 34 penetrate through the moving block 33, so that the guide of the moving block 33 during movement is achieved. A tensioning mechanism 50 is mounted on the top of the fixing plate 30, and the tensioning mechanism 50 is used for tensioning the wire body 23 when winding.
When in use, the rotating reciprocating screw rod 32 drives the moving block 33 to move, and when the moving block 33 moves to the end part of the reciprocating screw rod 32, the moving block 33 automatically moves to the other end, thereby achieving the effect of reciprocating the moving block 33 and the tensioning mechanism 50 and driving the wire body 23 positioned outside the winding roller 22 to reciprocate. The winding or the unwinding of the wire body 23 is matched with the winding roller 22, so that the effect that the wire body 23 is uniformly wound on the winding roller 22 is achieved.
The above-mentioned wind-up roll 22 often has an asynchronous condition when being matched with the moving block 33 (i.e. the position of the wind-up roll 22 winding the wire body 23 does not correspond to the position of the moving block 33) so that the winding of the outgoing wire body 23 is not tight, and therefore a synchronous mechanism is proposed.
Referring to fig. 1 and 2, the output end of the motor 25 is fixedly connected with a synchronous pulley 40, the left end of the reciprocating screw rod 32 extends out of the vertical plate 31 and is fixedly connected with the same synchronous pulley 40, and the outer sides of the two synchronous pulleys 40 are meshed with a synchronous belt 41. When one synchronous pulley 40 rotates, the other synchronous pulley 40 is driven to rotate in the same direction by the synchronous belt 41. Thereby achieving the effect of rotation synchronization of the wind-up roller 22 and the reciprocating screw 32, and further enabling the position of the wind-up roller 22 wound on the electric wire body 23 to correspond to the position of the moving block 33.
When the wire body 23 is pulled outwards or wound inwards, the wire body 23 may be too loose when the winding roller 22 winds the wire body 23 due to no restriction force, so that the effect of storing the wire body 23 on the winding roller 22 is poor, and the wire body 23 is unreeled from the winding roller 22, so that the wire body 23 is inconvenient to be pulled out and fixed on a wire pole. When the force of pulling the wire body 23 outwards is too large, the loose wire body 23 may directly drive the wind-up roller 22 to rotate rapidly, so that the length of the pulled wire body 23 is too long. The tensioning mechanism 50 is therefore proposed.
Referring to fig. 1, 4, 5, and 6, the tensioning mechanism 50 includes a through block 501, the through block 501 is penetrated from left to right, a pair of mirror-symmetrical movable slots 502 are respectively formed on front and rear sides of an inner portion of the through block 501, sliding rods 503 are fixedly connected to upper and lower sides of an inner portion of the movable slots 502, sliding blocks 504 are respectively and slidably connected to upper and lower sides of the sliding rods 503, supporting springs 505 are fixedly connected to outer sides of the sliding blocks 504, and the other sides of the supporting springs 505 are fixedly connected to the movable slots 502. The front and back sides corresponding to the opposite sides of the sliding block 504 are provided with turning rods 506, and the turning rods 506 are fixedly connected with guide wheels 507.
Preferably, the surface of the guide wheel 507 is arc-shaped, so that the opposite sides of the left and right groups of guide wheels 507 form a similar oval gap. When the electric wire body 23 is used, the outer side end of the electric wire body 23 sequentially passes through the opposite ends of the two guide wheels 507 at the left side and the right side, and the electric wire body 23 is slightly larger than a gap between the two guide wheels 507 at the beginning, so that when the outer side of the electric wire body 23 is inserted into the gap between the two guide wheels 507, the electric wire body 23 slightly and outwards expands the two guide wheels 507, the two guide wheels 507 move to enable the supporting springs 505 to be compressed and deformed, the deformed supporting springs 505 support the sliding blocks 504 and clamp the electric wire body 23 at the gap at the opposite sides of the two guide wheels 507, and extrusion force is applied to the electric wire body 23, so that constant tension is kept when the electric wire body 23 is wound or unwound, and the electric wire body 23 is prevented from being excessively loosened when being wound on the winding roller 22.
Preferably, referring to fig. 5, an inclined triangular block 35 is fixedly connected to the bottom of the penetrating block 501, and the bottom of the inclined triangular block 35 is fixedly connected to the top of the moving block 33. The inclined triangular block 35 gradually rises from left to right, so that the penetrating block 501 is designed to be low on the left and high on the right, and the electric wire body 23 can move obliquely when unreeling, and the electric wire body 23 can be conveniently connected with a telegraph pole at a high position.
After the winding or unwinding of the wire body 23 is completed, the winding roller 22 needs to be fixed, so that the winding roller 22 is prevented from rotating again due to natural rotation of the winding roller 22 caused by external wind power, and the wound wire body 23 is scattered again. A securing mechanism is therefore proposed.
Referring to fig. 2 and 7, the right end of the rotating rod 21 extends rightward to penetrate through the surface of the supporting plate 20, and a turntable 60 is mounted on the right side of the rotating rod 21, the turntable 60 includes a disc 601, a set of arc-shaped blocking pieces 602 are fixedly connected to the outer side of the disc 601, a section of gap 604 is formed between the two arc-shaped blocking pieces 602, and a groove 603 is formed at the joint of the two arc-shaped blocking pieces 602; the right side of the supporting plate 20 is fixedly connected with a second connecting plate 61, the left side and the right side of the top of the second connecting plate 61 are fixedly connected with a hollow pipe 62, the inside of the hollow pipe 62 is slidably connected with an extension rod 64, the bottom of the extension rod 64 is fixedly connected with a connecting spring 63, and the bottom of the connecting spring 63 is fixedly connected with the hollow pipe 62; the top of the two extension rods 64 is fixedly connected with an insertion block 65.
Preferably, the top of the insert 65 is triangular to fit the groove 603, and the top of the insert 65 is rounded. The top of the second connecting plate 61 is fixedly connected with an air cylinder 66, when the air cylinder 66 is started through an external power supply, the output end of the air cylinder 66 moves upwards to gradually contact with the bottom of the insert block 65 until the output end of the air cylinder 66 abuts against the bottom of the insert block 65 and continuously drives the insert block 65 to move upwards to abut against the groove 603 at the bottommost part of the turntable 60, so that the stopping of the turntable 60 is achieved, and the fixing of the winding roller 22 is further achieved. Meanwhile, when the output end of the air cylinder 66 is retracted, the insert 65 loses the restriction force on the turntable 60, so that the turntable 60 can freely rotate. When the winding roller 22 continues to unreel the electric wire body 23, the winding roller 22 rotates anticlockwise to drive the turntable 60 to rotate in the same direction, and the arc-shaped baffle 602 contacts with the top boundary of the insert block 65, so that the effect of reducing the rotation speed of the turntable 60 is achieved, the winding roller 22 is prevented from rotating too fast, and the abrasion of the joint of the rotating rod 21 and the supporting plate 20 is aggravated. When in use, the rotating force of the turntable 60 drives the insert blocks 65 to move downwards, meanwhile, the connecting springs 63 are driven to compress, when the lowest arc-shaped baffle plates 602 pass through the surface of the insert blocks 65, the connecting springs 63 lose pressing force to rebound to drive the insert blocks 65 to move upwards, the insert blocks 65 are positioned between the lowest notches 604, the time when the insert blocks 65 are not in contact with the turntable 60, the speed of the turntable 60 cannot be influenced, the rotating speed of the turntable 60 rises, when the insert blocks 65 are in contact with the next arc-shaped baffle plates 602, the speed is slowed down, the turntable 60 rotates to achieve a clamping effect, and the effect of speed reduction when the turntable 60 moves is achieved along with the reciprocating motion of the insert blocks 65 in cooperation with the rotating turntable 60, and meanwhile, when the arc-shaped baffle plates 602 are in surface contact with the insert blocks 65, the intermittent clamping effect is achieved.
When the winding roller 22 rotates due to the pulling force of the wire body 23 when unwinding, the winding roller 22 continues to rotate for a few weeks due to inertia when the pulling force is stopped, so as to drive the wire on the winding roller 22 to continuously unwind outwards, and further, because the tensioning mechanism 50 clamps the wire body 23, the continuously unwound wire is accumulated between the tensioning mechanism 50 and the winding roller 22, so that a section of the wire body 23 is always accumulated between the tensioning mechanism 50 and the winding roller 22 when the wire body 23 is subsequently unwound. The reducing mechanism not only does not reduce the inertia force of the winding roller 22 during rotation, but also has the clamping effect when the turntable 60 contacts with the surface of the inserting block 65, when the winding roller 22 rotates due to inertia, the winding roller 22 drives the turntable 60 to rotate, and the rotating inertia force of the winding roller 22 is reduced, the extruding force of the turntable 60 to the inserting block 65 cannot drive the inserting block 65 to too much downwards, the supporting force of the connecting spring 63 to the inserting block 65 is gradually larger than the extruding force of the turntable 60 to the inserting block 65, so that the turntable 60 slightly reverses, the winding roller 22 is driven to slightly reverse, and the wire body 23 is positioned in the middle of the tensioning mechanism 50 and the winding roller 22 by matching with the tensioning mechanism 50.
When the electric wire body 23 is wound up, the speed reducing mechanism is not required because the external electric wire body 23 is tensioned, and therefore, the speed reducing mechanism is set to be manually opened according to the need.
Referring to the figure, the front surface of the insert 65 is fixedly connected with a hook 67, and the front surface of the air cylinder 66 is fixedly connected with a fixing ring 68. When the speed reducing mechanism is not used, the insert block 65 is pressed to the lowest position, and the hooks 67 are hung on the fixing ring 68, so that the insert block 65 is fixed, and meanwhile, the insert block 65 is not contacted with the turntable 60 at the lowest position, so that the winding of the turntable 60 and the winding roller 22 is not affected.
The working principle of the invention is as follows: the outer side end of the wire body 23 sequentially passes through the opposite ends of the two guide wheels 507 on the left side and the right side, and the wire body 23 is slightly larger than the gap between the two guide wheels 507 at the beginning, so when the outer side of the wire body 23 is inserted into the gap between the two guide wheels 507, the wire body 23 slightly and outwards expands the two guide wheels 507, the two guide wheels 507 move to enable the supporting springs 505 to be compressed and deformed, the deformed supporting springs 505 support the sliding blocks 504 and clamp the wire body 23 at the gap on the opposite sides of the two guide wheels 507, and extrusion force is applied to the wire body 23, so that constant tension is kept when the wire body 23 is wound or unwound, and excessive looseness is prevented when the wire body 23 is wound on the winding roller 22. When the wire body 23 is installed behind the telegraph pole and needs to be tensioned, the motor 25 is started through an external power supply, and the output end of the motor 25 drives the winding roller 22 to rotate, so that the wire body 23 is wound on the winding roller 22. Thereby putting the wire in tension.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
