Description

Technical Field

[0001] The invention belongs to the field of degaussing cable laying, in particular to a vertical degaussing coil quick laying auxiliary device. Background Art

[0002] A ship is equivalent to a huge metal body. When it is sailing, the hull constantly cuts the earth's magnetic lines, generates magnetic induction current on the hull, enhances the ship's magnetic field, and changes the original characteristics of the ship's magnetic field, making the ship's magnetic characteristics very obvious and easy to identify. The main material of a warship is easily magnetized iron, and many instruments on it are equipped with artificial magnets (such as ammeters, voltmeters, etc.). The comprehensive magnetism of these artificial magnets is strong, and it is easy to magnetize the warship. The magnetized warship affects the accuracy of equipment, instruments, instruments, and especially weapons, which is not conducive to safety, so it is necessary to demagnetize. At present, before the demagnetization operation, the longitudinal demagnetization coil needs to be evenly wound around the hull. It is necessary to pull the cable manually and drop the longitudinal coil vertically around the hull. When the coil is retracted, the retracted cable often rubs against the edge of the ship's side. It is easy to cause the paint on the ship's side to fall off, and it also places high demands on the operator's physical strength. During the operation, the cables are stacked on the deck, resulting in a messy work site. Therefore, people need a vertical demagnetization coil quick laying auxiliary device to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a vertical degaussing coil quick laying auxiliary device to solve the problems in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A vertical demagnetization coil rapid laying auxiliary device comprises a shell, a first bracket is arranged inside the shell, a rotating shaft is arranged in the middle of the first bracket, the rotating shaft is rotatably connected to a rotating friction disk, the rotating shaft and the rotating friction disk are connected by a key, so that the connection is more stable and firm, a stationary friction disk is arranged on one side of the rotating friction disk, the stationary friction disk is slidably connected to a sleeve, the sleeve is spirally rotatably connected to a knob, a cable guide is arranged at the lower end of the shell, a cable reel is coaxially installed with the rotating friction disk and rotates at the same time, a square shaft is arranged on one side of the stationary friction disk, the square shaft slides axially in the sleeve, and under the adjustment of the knob on one side of the sleeve, the pressure between the rotating friction disk and the stationary friction disk is changed, thereby changing the friction between the two, and preventing the cable reel from being quickly lowered due to inertia.

[0006] As a further improvement of the above technical solution, a driven gear is provided at the other end of the rotating shaft, the driven gear is meshedly connected with the driving gear, the driving gear rotating shaft is connected to the rocking arm, the driven gear is meshedly connected with the driving gear, and the driving gear and the rocking arm are connected by a key. When the operator shakes the rocking arm, the rocking arm drives the driving gear to rotate, the driving gear is meshedly connected with the driven gear to rotate, and the driven gear drives the rotating shaft to rotate. The cable pulls the longitudinal cable, so that the cable can be retracted and released. When the knob adjusts the speed of the rotating friction disk, the shaking resistance of the rocking arm can also be indirectly controlled. If the knob presses the rotating friction disk to a slow speed or even no rotation, when the rocking arm is shaken to retract and release the cable, if it is necessary to pause the retraction and release of the cable, when the operator releases the rocking arm, due to the pressure of the stationary friction disk, the rotating friction disk will not rotate by itself under the inertia release of the cable reel, and the rotating friction disk will not drive the rocking arm to rotate too fast, causing damage to the personal safety of the operator.

[0007] As a further improvement of the above technical solution, a roller is provided on one side of the outer shell, and a cable hole is provided on the upper end of the roller. The head end of the cable passes through the cable hole and is placed on the roller. The setting of the long roller can meet the multi-directional retraction and release during the cable retraction and release operation, and avoid unidirectional jamming. When the roller is retracted and released in multiple directions, the brackets on both sides of the roller are away from the outer shell and the ship's side, and have less contact with the ship's side and the outer shell, which can avoid wear on the ship's side and protect the cable.

[0008] As a further improvement of the above technical solution, a base is provided at the lower end of the shell, and the base is connected to the cable guide through a locking tongue. An unlocking button is installed on one side of the locking tongue. The cable reel is connected to the cable guide via the base, which can save installation space. At the same time, the cable guide serves as a placement mechanism for transverse cables and can concentrate the transverse and longitudinal cable placement ends.

[0009] As a further improvement of the above technical solution, the unlocking button is located inside the fairlead, and the unlocking button is connected to the locking tongue through a connecting strip. After pressing the unlocking button, the unlocking button can drive the locking tongue to move in the groove, and the locking tongue extends or retracts, so that the quick laying device can be easily installed on the fairlead to fix the laying device.

[0010] As a further improvement of the above technical solution, a screw clamp is provided at the lower end of the fairlead, and the setting of the screw clamp can fix the fairlead on the ship's side. The screw clamp is connected to the silicone buffer pad, and the lower opening structure of the fairlead can be clamped on the ship's side. The silicone pads on both sides of the fairlead clamp the ship's side, which can prevent the fairlead from causing wear on the ship's side.

[0011] As a further improvement of the above technical solution, a first clamping head is provided on the inner side below the fairlead, and the device is fixed by the first clamping head;

[0012] The screw clamp comprises a threaded seat, a transmission screw, a second clamping head, a rotary bearing and a rotary nut;

[0013] A threaded seat is provided on the other side of the lower end of the fairlead, and the threaded seat is used to limit and fix the transmission screw while driving the transmission screw to move. The threaded seat is internally connected to a transmission screw through a threaded rotation, and a second clamping head is installed at one end of the transmission screw close to the first clamping head. The device can be effectively fixed by using the first clamping head and the second clamping head, so that the device can be stably fixed on the ship. The transmission screw and the second clamping head are rotationally connected by a rotating bearing, so that the transmission screw will not cause the second clamping head to rotate when it rotates, so that the second clamping head can move horizontally under the action of the transmission screw, and a rotating nut is provided on the other side of the transmission screw, and the transmission screw can be rotated by rotating the nut.

[0014] As a further improvement of the above technical solution, a first pulley is installed at the corner on one side of the fairlead, a second pulley is installed at the corner on the other side of the fairlead, and a third pulley is installed below the second pulley on one side of the fairlead. Through the rotation of the first pulley, the second pulley and the third pulley, the transverse cable can be retracted and released, and the cable can also be protected. When the cable is released, it can be prevented from rubbing against the ship's side and paint falling off.

[0015] As a further improvement of the above technical solution, the rocker is L-shaped, and a bent rod is provided at the bent part of the rocker, and the angles between the bent rod and the rocker are all acute angles, so that it is more labor-saving when using the rocker to rotate.

[0016] As a further improvement of the above technical solution, the first clamping head and the second clamping head are concave, and the inner walls of the first clamping head and the second clamping head are both bonded with rubber, so that the device is fixed using the first clamping head and the second clamping head more stably and slipping is avoided.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention is simple and reasonable in structure, and manages the cable release end in the housing, which solves the problem of random stacking of cables and messy site during operation in the traditional cable release process;

[0019] 2. Add a stationary friction disc on one side of the rotating friction disc. The stationary friction disc can adjust the pressure of the stationary friction disc under the knob adjustment, thereby adjusting the resistance of the rocker connected to the gear mechanism of the stationary friction disc. When the cable is normally retracted and released, the resistance of the stationary friction disc can be such that when the retraction and release is suspended, the rotating friction disc does not rotate or rotates slowly, so as to avoid the inertia release of the cable reel, which drives the rocker to endanger the operator. Adjusting the rotation resistance of the rocker can save manpower;

[0020] 3. A latch structure is added to the upper end of the fairlead. The latch includes an unlocking button and a locking tongue. The cable reel and the rotating friction disk mechanism are connected to the fairlead through the base, which can centrally manage the cable in the horizontal and vertical directions, while saving installation space. At the same time, the screw clamp at the lower end of the fairlead can fix the fairlead on the ship's side to prevent the cable from wearing and peeling off the ship's side during dragging. At the same time, the first pulley set at the upper end of the fairlead can also protect the cable.

[0021] 4. The present invention realizes the clamping of the fairlead by providing a screw clamp. At the same time, the screw clamp can be fixed on the side of the ship with different thicknesses and diameters, thereby improving the use range of the fairlead. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example: Figure 1-2As shown, a vertical demagnetization coil quick laying auxiliary device includes a shell 13, a first bracket 4 is arranged inside the shell 13, a rotating shaft 9 is arranged in the middle of the first bracket 4, the rotating shaft 9 is rotatably connected with a rotating friction disk 1, the rotating shaft 9 and the rotating friction disk 1 are connected by a key, a stationary friction disk 6 is arranged on one side of the rotating friction disk 1, the stationary friction disk 6 is slidably connected with a sleeve 7, the sleeve 7 is spirally connected with a knob 8, a fairlead 15 is arranged at the lower end of the shell 13, bearings are arranged on both sides of the rotating shaft 9, the bearings are fixedly connected to the first bracket 4 and the second bracket 5, so as to support the rotating shaft 9, and the rotating shaft 9 can be moved when the bearings are working. It is used to rotate between the first bracket 4 and the second bracket 5. The second bracket 5 is an H-shaped structure. A sleeve 7 is provided at the rear end of the H-shaped structure. The sleeve 7 is fixedly connected to the second bracket 5 with bolts. The left side of the sleeve 7 is a square shaft groove, and the right side is a spiral inner thread structure. A square shaft is integrally connected to the right side of the stationary friction disc 6. The square shaft slides on the left end of the sleeve 7, and a knob 8 provided on the right side of the sleeve 7 rotates within the inner thread on the right side of the sleeve 7. When the knob 8 is tightened, the screw of the knob 8 will push the square shaft of the stationary friction disc 6 to move leftward, thereby changing the pressure between the rotating friction disc 1 and the stationary friction disc 6, and then changing the friction between the two, and adjusting the rotation speed of the rotating friction disc 1.

[0030] A driven gear 10 is provided at one end of the rotating shaft 9, and a driving gear 11 is installed on one side of the driven gear 10. The driven gear 10 is meshedly connected with the driving gear 11. The rotating shaft of the driving gear 11 is connected to a rocker 12. The driving gear 11 and the rocker 12 are connected by a key. When the rocker 12 is shaken, the rocker 12 will drive the driving gear 11 to rotate. One end of the rotating shaft of the driving gear 11 is rotatably connected to a hole set in the housing 13, and the other end is connected to a hole set in the first bracket 4. When the driving gear 11 rotates, the meshing connected driven gear 10 rotates, and the driven gear 10 will drive the rotating shaft 9 to rotate, which can drive the rotating friction disk 1 to rotate, thereby driving the cable reel 2 passing through the rotating shaft 9 to rotate. The cable pulls the longitudinal cable, so that the cable can be retracted and released.

[0031] like Figure 3 As shown, a roller 3 is provided on one side of the shell 13, and a cable hole is provided on the upper end of the roller 3. When the cable is retracted or released, the cable passes through the cable hole of the shell 13 and is placed on the roller 3. The roller 3 is a long roller and can retract and release the cable in multiple directions. The brackets on both sides of the roller 3 can keep the roller 3 away from the shell 15 and the side of the ship. At the same time, the setting of the roller 3 can assist in buffering the retraction and release of the cable to avoid wear on the side of the ship and paint peeling.

[0032] A base 14 is provided at the lower end of the shell 13, and the base 14 is connected to the fairlead 15 through a locking tongue 18. The base 14 is connected to the fairlead 15, and an unlocking button 17 is installed on one side of the locking tongue 18, which can concentrate the longitudinal cable release mechanism of the cable reel 2 and the transverse cable release mechanism of the fairlead 15 in one place for easy management.

[0033] like Figure 4 As shown, the unlocking button 17 is located inside the fairlead 15, and the unlocking button 17 is connected to the locking tongue 18 through a connecting strip. There are two unlocking buttons 17, and they are symmetrically designed relative to the base 14, so that the cable reel 2 structure at the upper end of the fairlead 15 can be placed more stably. When the unlocking buttons at both ends are pressed, the unlocking button 17 retracts, and at the same time drives the locking tongue 18 to retract, so that the base 14 can be installed or disassembled. When the unlocking button 17 is released, the unlocking button 17 rebounds, which will drive the locking tongue 18 to rebound, and the locking tongue 18 will pass through the corresponding hole on the fairlead 15 to the locking tongue hole on the base 14, and the base 14 can be fixed at this time.

[0034] like Figure 3 As shown, a screw clamp 19 is provided at the lower end of the fairlead 15, a buffer silicone block is provided at the left end of the screw clamp 19, and a buffer silicone block is also provided on the other side of the fairlead 15. The opening at the lower end of the fairlead 15 can be clamped on the ship's side, and the adjusting knob 19 can fix the fairlead 15. At the same time, the setting of the buffer silicone can avoid wear and damage to the ship's side.

[0035] The rocker 12 is L-shaped, and a bending rod is provided at the bending part of the rocker 12. The angles between the bending rod and the rocker 12 are all acute angles. The design of two acute angles makes it more labor-saving to rotate the rocker 12.

[0036] The first clamping head 20 and the second clamping head 1903 are concave, and the inner walls of the first clamping head 20 and the second clamping head 1903 are both fitted with rubber. The contact between the rubber and the hull makes the device more stably fixed when in use.

[0037] like Figure 5 As shown, a first clamping head 20 is provided on the inner side below the fairlead 15;

[0038] The screw clamp 19 includes a threaded seat 1901, a transmission screw 1902, a second clamping head 1903, a rotary bearing 1904 and a rotary nut 1905;

[0039] A threaded seat 1901 is provided on the other side of the lower end of the cable guide 15. The threaded seat 1901 is used to fix the transmission screw 1902 and drive the movement of the transmission screw 1902. The transmission screw 1902 is rotatably connected to the inside of the threaded seat 1901 through a thread. The transmission screw 1902 is used to drive the second clamping head 1903. The second clamping head 1903 is installed at one end of the transmission screw 1902 close to the first clamping head 20. The device is fixed by the first clamping head 20 and the second clamping head 1903. The transmission screw 1902 and the second clamping head 1903 are rotatably connected by a rotating bearing 1904, which is used to realize the transmission between the second clamping head 1903 and the transmission screw 1902 to prevent the second clamping head 1903 from rotating when the transmission screw 1902 rotates. A rotating nut 1905 is provided on the other side of the transmission screw 1902.

[0040] A first pulley 16 is installed at a corner on one side of the fairlead 15, a second pulley 21 is installed at a corner on the other side of the fairlead 15, and a third pulley 22 is installed below the second pulley 21 and located on one side of the fairlead 15. When the transverse cable is retracted or released, the transverse cable is placed on the first pulley 16 at the upper end of the fairlead 15, which can ensure that the shape of the cable is relatively complete and avoid damage to the cable. It can also prevent the cable from rubbing against the side of the ship and causing paint loss on the hull.

[0041] The working principle of the present invention is: first, when the fairlead 15 is fixed on the ship's side by the screw clamp 19 at its lower end, first, align the first clamping head 20 with the ship's side on one side, then place the fairlead 15 horizontally, and then rotate the rotating nut 1905, so that the rotation of the rotating nut 1905 drives the transmission screw 1902 to rotate, and when the transmission screw 1902 rotates, it will move horizontally under the action of the threaded seat 1901. At this time, the horizontally moving transmission screw 1902 drives the second clamping head 1903 to move horizontally. Due to the action of the rotating bearing 1904, when the transmission screw 1902 rotates, the second clamping head 1903 will not rotate but move horizontally. When the second clamping head 1903 contacts the ship's side, under the action of the first clamping head 20 and the second clamping head 1903, the device can be stably fixed on the ship's side. At the same time, under the action of the rubber, the device The fixation is more stable, align the lock tongue hole of the base 14 with the lock tongue hole on the cable guide 15, push the unlocking button 17, push the lock tongue 18 into the cable guide 15, complete the fixation of the base 14, the cable reel 2 is coaxially installed with the rotating friction disc 1, and rotates at the same time. At this time, the head end of the cable is placed on the roller 3 through the cable hole set on one side of the shell 13, and the rocker 12 set on one side of the shell 13 is shaken to rotate the driving gear 11 connected to the rocker 12. The driving gear 11 is meshed and connected to the driven gear 10 to rotate. The driven gear 10 rotates and drives the rotating shaft 9 to rotate, which can drive the rotating friction disc 1 to drive the cable reel 2 to rotate. When the knob 8 on the right side of the rotating friction disc 1 is rotated, the screw rod of the knob 8 will push the square shaft on the right side of the stationary friction disc 6. The square shaft moves axially in the sleeve 7, which can push the stationary friction disc 6 to press the rotating friction disc 1, and adjust the friction force of the shaking rocker 12. The greater the force with which the stationary friction disk 6 presses the rotating friction disk 1, the greater the force with which the stationary friction disk 6 presses the rotating friction disk 1. When releasing or pausing the winding, stop shaking the rocker 12, and the cable reel 2 will not roll or will roll very slowly under the indirect pressure of the stationary friction disk 6, and will not cause the rocker 12 to rotate too fast to endanger the operator. When the cable needs to be released quickly, the rocker 12 can be removed and the knob 8 can be adjusted to quickly release or pause the cable.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
