Description

Technical Field

[0001] The present application relates to the field of bridge analysis, and in particular to an automatic coil winding device for measuring the suspension rod force using a magnetic flux method. Background Art

[0002] The hanger is the part of the bridge used to lift the bridge body, and the hanger force refers to the tension force of the hanger.

[0003] In the prior art, the use of a boom requires certain strength requirements, and the boom force is generally used as the strength standard of the boom. The boom force is generally tested by the magnetic flux method. When testing the boom force, a copper wire needs to be wound around the boom to be measured to form an induction coil, thereby inducing the magnetic field inside the boom and generating an induced voltage.

[0004] Generally, the copper wire is wound around the suspension rod manually. The copper wire constituting the induction coil is generally long, and the manual winding process is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0005] In order to improve the convenience of coil winding and to be able to automatically wind the coil, the present application provides an automatic coil winding device for measuring the suspension rod force using a magnetic flux method.

[0006] A device for automatically winding a coil for measuring the force of a suspension rod using a magnetic flux method comprises a base and a sleeve arranged on the suspension rod, one end of the sleeve is provided with a fixed wheel, a side of the base close to the sleeve is rotatably connected to a rotating rod, a driving wheel meshing with the fixed wheel is coaxially provided on the rotating rod, a through hole for the rotating rod to pass through is provided on the driving wheel, and a winding mechanism for evenly winding copper wire onto the sleeve along the height direction is provided on the side of the base close to the sleeve.

[0007] By adopting the above technical solution, the driving wheel is driven to rotate by the rotating rod, thereby driving the fixed wheel to rotate, and then the sleeve is rotated on the suspension rod. The copper wire is evenly wound on the sleeve along the height direction through the winding mechanism, thereby improving the convenience of coil winding.

[0008] Preferably, the winding mechanism comprises a fixing rod and a coil frame, wherein the fixing rod is arranged on a side of the base close to the sleeve, the coil frame is arranged on the fixing rod, and a penetration groove for the fixing rod to penetrate is opened on the coil frame.

[0009] By adopting the above technical solution, the fixing rod is pressed against the coil frame in the penetration groove, thereby reducing the horizontal slippage of the coil frame on the base. The copper wire is placed on the coil frame, and the copper wire is evenly wound along the height direction of the sleeve by the coil frame sliding in the height direction of the fixing rod, thereby improving the stability of the winding mechanism.

[0010] Preferably, the winding mechanism further comprises a reciprocating screw rod, which is rotatably connected to a side of the base close to the sleeve, and a threaded hole for the reciprocating screw rod to cooperate with is provided on the coil frame.

[0011] By adopting the above technical solution, the reciprocating screw rod is pressed against the coil frame in the threaded hole, thereby reducing the rotation of the coil frame along the circumferential direction of the fixed rod. When the reciprocating screw rod rotates, the coil frame is driven to continuously reciprocate in the height direction of the reciprocating screw rod, so that the copper wire is evenly wound along the height direction of the sleeve, thereby improving the stability of the winding mechanism.

[0012] Preferably, the coil frame comprises a fixed block and a coil barrel, the threaded hole and the through groove are provided on the fixed block, and the coil barrel is rotatably connected to the fixed block.

[0013] By adopting the above technical solution, the coil tube is used to gather the copper wire, and the fixed block slides back and forth in the height direction under the joint action of the reciprocating screw rod and the fixed rod, thereby driving the coil frame to slide back and forth in the height direction, so that the copper wire is evenly wound along the height direction of the sleeve, thereby improving the stability of the winding mechanism.

[0014] Preferably, the coil frame further comprises a wire wheel for guiding the copper wire to be wound onto the sleeve, and the wire wheel is rotatably connected to a side of the fixed block close to the sleeve.

[0015] By adopting the above technical solution, when the copper wire is wound onto the sleeve, the copper wire is output from the coil frame, and the copper wire contacts the wire wheel to drive the wire wheel to rotate, thereby reducing the wear caused by friction between the copper wire and the fixed frame, thereby improving the stability of the coil frame.

[0016] Preferably, a hinge is provided at one end of the sleeve, the hinge is sleeved on the driving wheel and the fixed wheel, and the hinge is meshed with the driving wheel and the fixed wheel at the same time.

[0017] By adopting the above technical solution, the inner ring of the hinge is pressed against the driving wheel and the fixed wheel at the same time, thereby reducing the situation where the driving wheel is separated from the fixed wheel and causes the driving wheel to spin idly, thereby improving the stability of the driving wheel.

[0018] Preferably, the fixing wheels are symmetrically arranged at both ends of the sleeve.

[0019] By adopting the above technical solution, the two fixed wheels are meshed with the two driving wheels respectively at the same time, thereby reducing the relative slip between the driving wheel and the fixed wheel due to excessive resistance when the driving wheel drives the fixed wheel, thereby improving the stability of the driving wheel.

[0020] Preferably, a limiting block is arranged on a side of the rotating rod close to the driving wheel, and a limiting groove for inserting and installing the limiting block is opened on the driving wheel.

[0021] By adopting the above technical solution, the limiting block presses against the driving wheel in the limiting groove, thereby reducing the situation where the driving wheel rotates circumferentially on the rotating rod and causes the fixed wheel to stop rotating, thereby improving the stability of the driving wheel in use.

[0022] Preferably, the base includes a first bracket and a second bracket, the rotating rod is arranged on the first bracket, the reciprocating screw rod and the fixed rod are arranged on the second bracket, a limiting column is arranged on the side of the first bracket close to the second bracket, and a limiting cavity for inserting the limiting column is opened on the second bracket.

[0023] By adopting the above technical solution, the limiting column presses against the second bracket in the limiting cavity, thereby reducing the relative slippage of the first bracket and the second bracket, and further reducing the deviation of the driving wheel and the winding mechanism, thereby improving the stability of the base.

[0024] Preferably, a first driving member for driving the rotating rod to rotate is disposed on a side of the first bracket close to the rotating rod, and a second driving member for driving the reciprocating screw to rotate is disposed on a side of the second bracket close to the reciprocating screw.

[0025] By adopting the above technical solution, the rotation speed of the driving wheel is controlled by the first driving member, thereby controlling the rotation speed of the sleeve, and the reciprocating speed of the coil frame on the reciprocating screw rod is controlled by the second driving member, thereby controlling the coil to be evenly wound on the sleeve, thereby improving the stability of the automatic coil winding device.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The rotating rod drives the driving wheel to rotate, thereby driving the fixed wheel to rotate, and then the sleeve rotates on the boom. The copper wire is evenly wound on the sleeve along the height direction through the winding mechanism, thereby improving the convenience of coil winding;

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an automatic coil winding device for measuring the force of a suspension rod using a magnetic flux method, comprising a base 2, a sleeve 1, a fixed wheel 3, a rotating rod 5, a driving wheel 4, a first driving member 23 and a winding mechanism 7. A cavity is reserved on the base 2 for the suspension rod 25 to pass through, and the base 2 is divided into a first bracket 19 and a second bracket 20 with the suspension rod 25 as the center. The sleeve 1 is sleeved on the suspension rod 25, and the copper wire is wound on the sleeve 1 to form an induction coil. The fixed wheel 3 is integrally arranged at both ends of the sleeve 1, and the sleeve 1 and the fixed wheel 3 are composed of two parts arranged in the height direction. The rotating rod 5 is rotatably connected to the side of the first bracket 19 close to the sleeve 1, and the driving wheel 4 is coaxially welded on the rotating rod 5. The driving wheel 4 is provided with a penetration hole 6 for the rotating rod 5 to pass through, and the driving wheel 4 is meshed with the fixed wheel 3. The first driving member 23 is disposed on the first bracket 19, and the rotating rod 5 is disposed on the driving shaft of the first driving member 23. The first driving member 23 is used to drive the rotating rod 5 to rotate. In this embodiment, a motor is used as an example. The winding mechanism 7 is disposed on the second bracket 20, and the winding mechanism 7 is used to drive the copper wire to be evenly wound onto the sleeve 1 along the height direction.

[0036] Reference Figure 1 and Figure 2 A limit block 17 is integrally provided on the side of the rotating rod 5 close to the driving wheel 4, and a limit groove 18 for installing the limit block 17 is provided on the driving wheel 4. The limit block 17 presses against the driving wheel 4 in the limit groove 18, thereby reducing the situation where the driving wheel 4 rotates along the circumferential direction on the rotating rod 5. A hinge 16 is sleeved on the fixed wheel 3, and the hinge 16 is meshed with the fixed wheel 3 and the driving wheel 4 at the same time, thereby reducing the situation where the driving wheel 4 is separated from the fixed wheel 3 and causes the driving wheel 4 to rotate idly.

[0037] Reference Figure 1 and Figure 3The winding mechanism 7 includes a fixed rod 8, a reciprocating screw rod 11 and a coil frame 9. The fixed rod 8 is welded to the side of the second bracket 20 close to the sleeve 1, and the coil frame 9 is provided with a penetration groove 10 for the fixed rod 8 to penetrate. The reciprocating screw rod 11 is rotatably connected to the side of the second bracket 20 close to the sleeve 1, and the coil frame 9 is provided with a threaded hole 12 for the reciprocating screw rod 11 to cooperate with. The threaded portion of the reciprocating screw rod 11 is set corresponding to the length of the sleeve 1, and the reciprocating screw rod 11 is used to drive the coil frame 9 to reciprocate along the height direction on the reciprocating screw rod 11. When the reciprocating screw rod 11 rotates to drive the coil frame 9 to reciprocate, the fixed rod 8 presses against the coil frame 9 in the penetration groove 10, thereby reducing the rotation of the coil frame 9 in the circumferential direction of the reciprocating screw rod 11. A second driving member 24 for driving the reciprocating screw 11 to rotate is disposed on one side of the second bracket 20 close to the sleeve 1. The reciprocating screw 11 is fixed on a driving shaft of the second driving member 24. In this embodiment, a motor is taken as an example.

[0038] Reference Figure 1 and Figure 3 The coil frame 9 includes a fixed block 13, a coil barrel 14 and a wire pulley 15. The threaded hole 12 and the threading groove 10 are both arranged on the fixed block 13. The coil barrel 14 is rotatably connected to the fixed block 13. The coil barrel 14 is used to gather the copper wire. The wire pulley 15 is rotatably connected to the side of the fixed block 13 close to the sleeve 1. When the fixed wheel 3 drives the sleeve 1 to rotate, the rotation of the sleeve 1 drives the copper wire to be wound around the sleeve 1. The friction between the copper wire and the wire pulley 15 drives the wire pulley 15 to rotate, thereby reducing wear.

[0039] Reference Figure 2 and Figure 3 A limiting column 21 is symmetrically arranged on one side of the first bracket 19 close to the second bracket 20. A limiting cavity 22 for installing the limiting column 21 is opened on the second bracket 20. The limiting column 21 presses against the second bracket 20 in the limiting cavity 22 to reduce the relative sliding of the first bracket 19 and the second bracket 20.

[0040] Working process:

[0041] 1. The first driving member 23 drives the rotating rod 5 to rotate, thereby driving the driving wheel 4 to rotate, and then driving the fixed wheel 3 meshing with the driving wheel 4 to rotate, and finally driving the sleeve 1 to rotate on the suspension rod 25;

[0042] 2. Pull one end of the copper wire out of the coil barrel 14, and wind one end of the copper wire onto the sleeve 1 through the wire wheel 15. At this time, the rotation of the sleeve 1 drives the copper wire to be wound onto the sleeve 1;

[0043] 3. The second driving member 24 drives the reciprocating screw 11 to rotate. At this time, the reciprocating screw 11 is pressed against the fixed block 13 in the threaded hole 12 to drive the fixed block 13 to reciprocate on the reciprocating screw 11 along the height direction. The fixed rod 8 is pressed against the fixed block 13 in the penetration groove 10 to reduce the circumferential rotation of the fixed block 13 on the reciprocating screw 11, so that the copper wire is evenly wound on the sleeve 1 along the height direction of the sleeve 1.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
