Description

Technical Field

[0001] The invention relates to the technical field of wire winding equipment, and in particular to a pipeline retracting and releasing mechanism with durable elasticity. Background Art

[0002] The pipeline retracting and releasing device is a device commonly used to store wires and water pipes in industry, agriculture, mine fire protection, etc., such as spring-type reels, hysteresis-type, electric friction plate-type, coupling-type and other winding devices. The spring-type reel can always have elastic force during the process of retracting and releasing the wire, tighten the cable, cause less damage to the cable, has a good degree of fit, and the running speed of the equipment carried can be adjusted, but its biggest disadvantage is that it cannot retract and release the cable over a long distance. Magnetic hysteresis-type, electric friction plate-type, coupling-type and other winding devices are relatively complex and fragile, and it is difficult to control the retracting and releasing force and speed. For longer pipelines, the diameter of the winding reel needs to be large enough, and its installation space and use are limited. Therefore, it is necessary to design a pipeline retracting and releasing mechanism with small size, unlimited winding distance, and the ability to meet the instantaneous acceleration and deceleration of the equipment carried, and with long-lasting elasticity. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and propose a pipeline retracting and releasing mechanism which is small in size, has unlimited winding distance, can meet the instantaneous acceleration and deceleration of the carried equipment, and has durable elasticity.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A pipeline retracting and releasing mechanism with durable elasticity comprises a housing assembly and also comprises:

[0006] The winding reel drives a hollow main shaft, which is arranged on the housing assembly and has a screw coaxially arranged at one end;

[0007] A winding drum, a fixed sleeve is arranged on the outer periphery of the hollow main shaft driven by the winding drum, and is used for winding the pipeline;

[0008] A coil spring is fixedly arranged on one end of the hollow main shaft driving the winding drum close to the screw rod;

[0009] The coil spring drives the hollow main shaft, which is arranged on the housing assembly through a bearing, and is sleeved on the outer periphery of the screw rod and the coil spring, and is fixedly connected to the outer ring of the coil spring, and transverse slide grooves are arranged on both sides;

[0010] A movable sliding sleeve is threadedly connected to the screw rod, sleeved on the hollow main shaft driven by the coil spring, and can slide along the sliding groove;

[0011] The coil spring driven brake motor is used to drive the coil spring to drive the hollow spindle to rotate forward and reverse and keep it stationary;

[0012] The induction switch is used to sense the position of the moving sleeve to control the forward rotation, power off and reverse rotation of the coil spring driven brake motor.

[0013] In the above structure, the cable reel drives the cable reel-driven hollow main shaft to rotate as the pipeline is reeled in and out, and at the same time, drives the screw to rotate, causing the movable sleeve to move left and right, thereby triggering the induction switches of the corresponding functions, thereby controlling the forward, stop and reverse rotation of the coil spring-driven brake motor. The movable sleeve rotates simultaneously with the coil spring-driven hollow main shaft, and through the screw fixed on the cable reel-driven hollow main shaft, the movable sleeve moves left and right along the transverse groove on the coil spring-driven hollow main shaft, and senses the induction switches of the corresponding functions, thereby achieving the purpose of forward, stop and reverse rotation.

[0016] Furthermore, the outer ring of the coil spring is connected to the hollow main shaft driven by the coil spring through a coil spring outer ring locking screw, and the inner ring of the coil spring is connected to the hollow main shaft driven by the winding reel through a coil spring inner ring locking sleeve.

[0017] Furthermore, the movable sleeve includes a circular ring and an intermediate beam, the two ends of the intermediate beam are fixedly connected to the inner wall of the circular ring, the center of the intermediate beam is threadedly connected to the screw, and the intermediate beams located on the upper and lower sides of the screw respectively penetrate the two slide grooves opened by the coil spring-driven hollow main shaft. The above structural setting can not only realize the threaded connection between the movable sleeve and the screw, and the movable sleeve can slide back and forth along the coil spring-driven hollow main shaft, but also realize that the coil spring drives the hollow main shaft to rotate while driving the movable sleeve to move on the screw.

[0019] Furthermore, the induction switch includes a power-off switch, a forward switch and a reverse switch, and the power-off switch is located between the forward switch and the reverse switch.

[0020] Furthermore, the pipeline retracting and releasing mechanism with durable elasticity also includes a controller, and the controller is connected to a coil spring driven brake motor, a switch and other equipment to achieve automatic control.

[0021] Furthermore, the housing assembly is provided with a wire arrangement mechanism, which includes a reciprocating screw and a sliding wire guide wheel arranged on the reciprocating screw; the reciprocating screw can drive the sliding wire guide wheel to move back and forth to arrange the wires.

[0022] Furthermore, the output end of the coil spring driven brake motor is connected to the driving sprocket, and the coil spring driven hollow main shaft is fixedly provided with a passive sprocket, and the driving sprocket and the passive sprocket are connected through a transmission chain. The coil spring driven brake motor drives the driving sprocket, and the passive sprocket is rotated forward and reversely through the transmission chain, thereby realizing the forward and reverse rotation of the coil spring driven hollow main shaft.

The bearing is arranged on the housing assembly 12, and is sleeved on the outer periphery of the screw 5 and the coil spring 7, and is fixedly connected to the outer ring of the coil spring 7 through the coil spring outer ring locking screw 9, and transverse slide grooves 19 are arranged on both sides; the movable sleeve 6 is threadedly connected to the screw 5, and is sleeved on the coil spring driven hollow main shaft 4, and can move left and right along the slide groove 19; the induction switch is used to sense the position of the movable sleeve 6 to control the forward rotation, power off and reverse rotation of the coil spring driven brake motor 11; the coil spring driven brake motor 11 is used to drive the coil spring driven hollow main shaft 4 to rotate forward and reverse and keep it stationary.

[0037] As a feasible implementation method, the output end of the coil spring driven brake motor 11 is connected to the driving sprocket 20, and the coil spring driven hollow main shaft 4 is fixedly provided with a passive sprocket 21, and the driving sprocket 20 and the passive sprocket 21 are connected through a transmission chain 22. The coil spring driven brake motor 11 drives the driving sprocket 20, and the passive sprocket 21 is realized through the transmission chain 22, thereby realizing the forward and reverse rotation of the coil spring driven hollow main shaft 4. As another feasible implementation method, a gear can be set on the coil spring driven hollow main shaft 4, and a gear is also set at the output end of the coil spring driven brake motor 11, and both gears are meshed with the intermediate gear, so that the coil spring driven brake motor 11 drives the coil spring driven hollow main shaft 4 to rotate.

[0038] The main box 18 is arranged in the cable reel 1, one end of the main box 18 is fixedly connected to the outer shell assembly 12, and the other end is connected to the cable reel driving hollow main shaft 3 through a bearing. When the cable reel drives the hollow main shaft 3 to rotate, the main box 18 remains stationary, and the cable reel 1 and the main box 18 do not affect each other; the coil spring 7, the coil spring driven hollow main shaft 4, the coil spring driven brake motor 11 and the switch are all arranged inside the cable reel 1, which is conducive to the installation of various components. For example, the coil spring driven brake motor 11, the switch, etc. can be installed on the outer shell assembly 12, and can also be installed on the main box 18.

[0043] Working principle:

[0044] In the pipeline retracting and releasing mechanism with durable elasticity described in the present invention, in the initial state, the movable sleeve 6 is located at the position of the forward switch 14. When the power is connected to the cable, the coil spring driving brake motor 11 starts to rotate forward, so that the coil spring 7 fixed between the coil spring driving hollow main shaft 4 and the reel driving hollow main shaft 3 starts to increase the elastic force, and starts to drive the reel 1 to rotate forward through the reel driving hollow main shaft 3. The cable is completely wound into the reel 1 until the reel 1 is pulled by the fixed power supply end to stop the reel 1 from rotating. At this time, since the screw rod 5 and the reel driving hollow main shaft 3 are integrated, the screw rod 5 also stops rotating. At this time, the coil spring driving brake motor 11 does not stop rotating, causing the movable sleeve 6 to start to move right, until the movable sleeve 6 moves to the power off switch 13, triggering the stop signal, and the controller 16 controls the coil spring driving brake motor 11 to stop rotating forward. At this time, the capacity tightness of the coil spring 7 does not exceed half.

[0045] In the working state, the coil spring driven brake motor 11 stops rotating due to the position of the movable sleeve 6 at the power-off switch 13, and the wire-releasing action starts at this time. The wire reel 1 drives the wire reel to drive the hollow main shaft 3 to rotate counterclockwise. At this time, the movable sleeve 6 does not rotate under the static force of the coil spring driven brake motor 11, but moves to the right along the transverse groove 19 of the coil spring driven hollow main shaft 4 under the action of the screw 5 (at this time, the coil spring 7 drives the hollow main shaft 3 to rotate through the coil reel, driving the coil spring inner ring locking sleeve 8 to continue to compress and accumulate force to increase the capacity), until the reverse switch 15 is triggered, and the coil spring drive is controlled by the controller 16. The brake motor 11 starts to reverse. At this time, the rotation speed of the brake motor 11 driven by the coil spring exceeds the winding reel 1 and the winding reel driven hollow main shaft 3, and the rotation speed is the fastest speed of unwinding (at this time, the coil spring 7 reverses along with the coil spring driven brake motor 11, that is, the coil spring drives the brake motor 11 through the coil spring driven hollow main shaft 4, and then through the coil spring outer ring locking screw 9, drives the coil spring 7 to reverse and release the coil spring capacity and reduce the stored force), so that the movable sleeve 6 moves to the left under the clockwise rapid drive of the coil spring driven hollow main shaft 4 until the power-off switch 13 is triggered, and the rotation of the coil spring driven brake motor 11 and the mechanism connected to it is stopped.

[0046] The wire-winding action is as follows: the wire reel 1 is subjected to the rotational force released by the winding spring 7, and the winding reel drives the hollow main shaft 3 to drive the wire reel 1 to rotate clockwise to achieve the purpose of winding; and at the same time, the screw 5 is driven to rotate clockwise, so that the movable sleeve 6 which does not rotate but can slide moves to the left until the forward rotation switch 14 is triggered. At this time, the controller 16 controls the winding spring to drive the brake motor 11 to start forward rotation (the rotation speed of the winding spring to drive the brake motor 11 exceeds the speed of the wire reel 1), so that the movable sleeve 6 gradually disengages from the forward rotation switch 14 and triggers the power-off switch 13, and the winding spring drives the brake motor 11 to stop forward rotation, and at the same time, the force released by the winding spring 7 is replenished, and this cycle repeats itself. Whether it is winding or releasing the wire, the winding spring 7 has sufficient elastic force to run back and forth between the trigger switches, which does not exceed the bearing range of the winding spring 7 and maintains sufficient elastic force to allow the wire reel 1 to be normally wound and released.

[0047] The above-mentioned specific implementation modes are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the above-mentioned specific implementation modes.
