Description

Technical Field

[0001] The present invention relates to the technical field of windproof cable devices, and particularly relates to an automatic windproof cable. Background Art

[0002] An automatic windproof cable is an automated windproof device used for large-scale lifting equipment, such as port portal cranes, ship unloaders, and quay cranes. Its core function is to automatically fix and unlock the equipment through an electromechanical integration structure during the non-working state to prevent the equipment from moving or tipping over due to strong winds.

[0003] In the Chinese patent with the publication number CN214059651U, an automatic windproof cable device for large port equipment is disclosed, including: a mounting seat, an anchoring block, and a telescopic assembly. The mounting seat is fixedly connected to the large port equipment body and is internally provided with a force sensor. The anchoring block is fixed to the foundation and is provided with a card slot. The telescopic assembly includes a driving assembly and a clamping part. The fixed end of the driving assembly is rotatably connected to the mounting seat. The clamping part is connected to the output end of the driving assembly and is clamped in the card slot. The windproof cable device may further include a swinging assembly, which is respectively connected to the large port equipment body and the driving assembly for driving the driving assembly and the clamping part to be clamped in the card slot. This application document may solve the technical problem in the prior art that the windproof cable device requires manual auxiliary positioning and pre-tightening, which may consume a large amount of physical strength of workers.

[0004] The above patent document solves the problem that the windproof cable device in the prior art requires manual auxiliary positioning and pre-tightening, which may consume a large amount of physical strength of workers. However, for the cable tightened by the continuous impact of typhoons, it is easy to cause an increase in wear between the screw rod and the sleeve, and even cause a fracture at the internal mating part, resulting in the failure of the cable, thus causing the failure of fixing the large machinery. At the same time, if the typhoon impacts the cable and causes the device to deform and unable to automatically contract normally, it will affect the normal use and reduce the service life of the cable. Summary of the Invention

[0013] Preferably, a plurality of limiting boxes are arranged at intervals along the circumferential direction on the end face of the first fixing ring. Openings are formed on the limiting boxes. A limiting block is elastically slidably arranged inside the limiting box. The limiting block can slide closer to or away from the opening inside the limiting box. A first inclined surface is formed on the limiting block. A pushing block is arranged on the end face of the second fixing ring facing the first fixing ring, and the pushing block can cooperate with the first inclined surface to limit and fix the threaded sleeve.

[0014] Preferably, a sleeve is arranged on one side end face of the second fixing ring, and the bottom of the sleeve has an opening. A spiral guiding groove is axially formed inside the sleeve, and there are two spiral guiding grooves which are symmetrically distributed on the inner ring surface of the sleeve. A plurality of rotating rods are arranged at intervals along the circumferential direction on the end face of the first fixing ring. A pushing rod is fixedly arranged on the outer peripheral surface of the rotating rod. An extrusion inclined surface is formed at one end of the pushing rod close to the threaded sleeve.

A friction block is slidably and sealingly arranged inside the hydraulic friction member, and the chamber formed by the friction block and the inner bottom wall of the hydraulic friction member is an oil chamber.

[0016] Preferably, the slip detection assembly includes: a detection ring and a contact head.

[0020] The beneficial effects of the present invention are as follows:

[0023] 3. The dual locking mechanism. The inclined surface cooperation between the limiting block and the pushing block realizes the radial locking of the threaded sleeve, and the hydraulic friction member drives the friction block to axially fix the threaded tie rod through oil pressure. The dual locking prevents the structural slip or loosening caused by typhoon impact.

[0024] 4. The redundant operation design is equipped with dual operation modes of electric drive and manual nut, and the emergency locking or release can still be completed by manually turning the nut in case of power failure, ensuring reliability under extreme working conditions.

[0025] 5. The synchronous action of multiple cable mechanisms is realized through the electric control cabinet, and the pre-tightening force is controlled by setting the threshold value of the pressure sensor, improving the efficiency and consistency of the overall windproof cable fixation of large equipment.

Detailed implementation manners

[0041] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] As Figures 1 to 13 shown, an automatic windproof cable of the present invention includes: a cylinder body 10, a threaded sleeve 20, two threaded tie rods 30, a fixing assembly, a sliding detection assembly and a lubrication mechanism 90. The threaded sleeve 20 is rotatably arranged inside the cylinder body 10 along the axial direction. The two threaded tie rods 30 are respectively connected to both ends of the threaded sleeve 20, and the two are in threaded cooperation so that the threaded sleeve 20 can drive the two threaded tie rods 30 to approach or move away from each other. At the same time, both ends of the two threaded tie rods 30 are respectively connected to the cable. The fixing assembly is arranged on the outer peripheral surface of the threaded sleeve 20, and the fixing assembly can limit and fix the threaded sleeve 20 and the threaded tie rods 30. The sliding detection assembly and the lubrication mechanism 90 are arranged inside the cylinder body 10, and the sliding detection assembly can detect the threaded cooperation of the threaded sleeve 20 and the threaded tie rods 30, so as to drive the lubrication mechanism 90 to lubricate it accurately, thereby ensuring the service life of the device.

[0043] When it is necessary to fix large port machinery, the two ropes respectively connected to the two threaded tie rods 30 are connected to the large machinery and the ground fixing ring respectively. Subsequently, the threaded sleeve 20 rotates to drive the two threaded tie rods 30 to move towards each other, thereby pulling the ropes corresponding to the two threaded tie rods 30 to automatically tighten, so as to quickly fix the machinery. Subsequently, the fixing component limits and fixes the outer peripheral surface of the threaded sleeve 20 to prevent the threaded sleeve 20 from rotating under the impact of a typhoon. At the same time, the fixing component fixes the threaded tie rod 30 to prevent the threaded tie rod 30 from axially moving under the impact of a typhoon, thereby avoiding an increase in wear of the threaded tie rod 30 and the threaded sleeve 20 caused by the typhoon impact, ensuring the service life of the device, and improving the stability of the device when fixing the machinery. The slip detection component and the lubrication mechanism 90 can accurately detect and lubricate the threaded tie rod 30 and the threaded sleeve 20, facilitating automated maintenance and lubrication and reducing the manual workload.

[0044] As shown in Figures x to x, both ends of the threaded sleeve 20 penetrate through both ends of the cylinder body 10, and a bearing is provided on the outer peripheral surface of the threaded sleeve 20 at the penetration position, so that the threaded sleeve 20 is rotatably connected to the cylinder body 10 through the bearing. A first toothed ring 21 is fixedly provided on one end surface of the threaded sleeve 20, and the inner diameter of the first toothed ring 21 is the same as the inner diameter of the threaded sleeve 20. A driving component is provided inside the cylinder body 10, and the output end of the driving component is in transmission connection with the first toothed ring 21, so that the driving component can drive the first toothed ring 21 and the threaded sleeve 20 to rotate. The inside of the threaded sleeve 20 is in threaded cooperation with the two threaded tie rods 30 respectively, and the threading directions of the two threaded tie rods 30 are opposite, so that the rotation of the threaded sleeve 20 can drive the two threaded tie rods 30 to move in opposite directions. An opening is provided on the outer peripheral surface of the threaded sleeve 20, which facilitates lubrication, grinding, and correction of the threaded tie rod 30. Two limiting grooves 34 are axially provided on the outer peripheral surface of the threaded tie rod 30, and the two limiting grooves 34 are symmetrically provided on the outer peripheral surface of the threaded tie rod 30.

[0045] As shown in Figures x to x, in this embodiment, there are two groups of fixing components, and the two groups of fixing components are symmetrically arranged on the outer peripheral surface of the threaded sleeve 20 along the axial direction to fix the threaded sleeve 20 and the two threaded tie rods 30. One group of fixing components includes: a first fixing ring 40, a second fixing ring 41, a limiting ring 44, a plurality of first tension rods 42, and a second tension rod 43. The first fixing ring 40 is fixedly provided on the inner wall of the end surface of the cylinder body 10, and the first fixing ring 40 is sleeved on the outer peripheral surface of the threaded sleeve 20. The plurality of first tension rods 42 are evenly spaced along the circumferential direction on the end surface of the first fixing ring 40. The second fixing ring 41 is sleeved on the outer peripheral surface of the threaded sleeve 20, and the top extension ends of the plurality of first tension rods 42 are connected to one side end surface of the second fixing ring 41, so that the first tension rods 42 can drive the second fixing ring 41 to move away from or close to the first fixing ring 40 along the axial direction of the cylinder body 10.

[0046] A plurality of limit boxes 45 are circumferentially spaced on the end face of the first fixing ring 40. The side wall of each limit box 45 close to the center position of the first fixing ring 40 is arranged as an arc surface, and the arc surface is in fit with the outer peripheral surface of the threaded sleeve 20. An opening is formed in the arc surface of the limit box 45 close to the center position of the first fixing ring 40. A limit block 47 is elastically and slidably arranged inside the limit box 45. The limit block 47 can slide in the limit box 45 close to or away from the opening. The side wall of the limit block 47 at the opening position is also an arc surface, increasing the contact area between the limit block 47 and the outer peripheral surface of the threaded sleeve 20, improving the stability of fixing the threaded sleeve 20. A first inclined surface 48 is formed on the limit block 47 as shown in Figure 7 shown. A pushing block 46 is arranged on the end face of the second fixing ring 41 facing the first fixing ring 40, and the pushing block 46 can cooperate with the first inclined surface 48 to limit and fix the threaded sleeve 20.

[0047] Therefore, after tightening a large machine with a rope, it is necessary to limit and fix the threaded sleeve 20 and the threaded sleeve 20 to avoid increasing the wear of the threaded rod 30 and the threaded sleeve 20 under the impact of a typhoon. Therefore, a plurality of first tension rods 42 stretch the second fixing ring 41 to approach the first fixing ring 40. At the same time, the movement of the second fixing ring 41 drives the pushing block 46 to move, so that the pushing block 46 contacts the first inclined surface 48. The continuous movement of the second fixing ring 41 enables the pushing block 46 to cooperate with the first inclined surface 48 and squeeze the limit block 47 to move towards the opening of the limit box 45. Finally, the limit block 47 contacts the outer peripheral surface of the threaded sleeve 20, and the plurality of limit blocks 47 apply a radial extrusion force to the threaded sleeve 20, thereby realizing the fixing of the threaded sleeve 20, avoiding the axial shaking or circumferential rotation of the threaded sleeve 20, and thus improving the stability of the entire cable.

[0048] As shown in Figures 5 to 7As shown in the figure, in order to further fix the threaded sleeve 20 and at the same time be able to limit and compensate the limit block 47, a sleeve 50 is provided on one end face of the second fixing ring 41, and the bottom of the sleeve 50 has an opening. A spiral guiding groove 51 is axially formed inside the sleeve 50, and there are two spiral guiding grooves 51 which are symmetrically distributed on the inner ring surface of the sleeve 50. A plurality of rotating rods 52 are circumferentially spaced on the end face of the first fixing ring 40. The rotating rod 52 is rotatably connected to the first fixing ring 40 and a torsion spring is provided at the connection position between the two. A push rod 53 is fixedly provided on the outer peripheral surface of the rotating rod 52. An extrusion inclined surface 54 is formed at one end of the push rod 53 close to the threaded sleeve 20. The torsion spring makes the extrusion inclined surface 54 of the push rod 53 separated from the threaded sleeve 20 in the initial state. A guiding block 55 is provided on the outer peripheral surface of the rotating rod 52. The guiding block 55 is matched with the spiral guiding groove 51. It should be noted that the extrusion inclined surfaces 54 at the ends of the push rods 53 on both sides of each first tension rod 42 are symmetrical, so that adjacent two push rods 53 apply pushing forces in different directions to the outer peripheral surface of the threaded sleeve 20, thereby preventing the threaded sleeve 20 from rotating circumferentially.

[0049] Therefore, when a plurality of first tension rods 42 stretch the second fixing ring 41 to approach the first fixing ring 40, the second fixing ring 41 drives the sleeve 50 to move towards the rotating rod 52. When the sleeve 50 is sleeved on the outer peripheral surface of the rotating rod 52, the sleeve 50 continues to move downward so that the guiding block 55 is matched with the spiral guiding groove 51, causing the rotating rod 52 to rotate and drive the push rod 53 to rotate. As a result, the extrusion inclined surface 54 of the push rod 53 abuts against the outer peripheral surface of the threaded sleeve 20 and applies a pushing force to fix the threaded sleeve 20, so that the threaded sleeve 20 can be stably fixed in the circumferential and axial directions. At the same time, the fixing components are all sleeved on the outer peripheral surface of the threaded sleeve 20, which can improve the rigidity of the threaded sleeve 20, prevent the threaded sleeve 20 from being bent or damaged by typhoon impact, and ensure the service life of the device.

[0050] As shown in Figures x to x, it is necessary to fix both the threaded tie rod 30 and the threaded sleeve 20 simultaneously to avoid increased wear caused by typhoon impact. Therefore, a plurality of second tension rods 43 are provided on the end face of the second fixing ring 41 away from the first fixing ring 40, and the second tension rods 43 are evenly spaced circumferentially. The limiting ring 44 is sleeved on the outer peripheral surface of the threaded sleeve 20, and the tension end of the second tension rod 43 is connected to the limiting ring 44 so that the limiting ring 44 can move along the axial direction of the threaded sleeve 20. Support blocks 35 are symmetrically arranged on the inner ring surface of the limiting ring 44. Hydraulic friction members 36 are provided on the opposite side walls of the support blocks 35, and the hydraulic friction members 36 are located in the limiting grooves 34. A friction block 38 is slidably and sealed inside the hydraulic friction member 36. The chamber formed by the friction block 38 and the inner bottom wall of the hydraulic friction member 36 is the oil chamber 37. The oil chamber 37 is filled with hydraulic oil. An annular pipeline is provided inside the limiting ring 44 to communicate the two hydraulic friction members 36. An oil inlet hole is provided on the limiting ring 44 and is connected to an oil pump.

[0051] When limiting and fixing the threaded tie rod 30, the second tension rod 43 pushes the limiting ring 44 to move. The movement of the limiting ring 44 drives the support blocks 35 and the hydraulic friction members 36 to move, so that the hydraulic friction members 36 slide in the limiting grooves 34. When the hydraulic friction members 36 slide to one end side wall of the limiting grooves 34, they stop moving. Subsequently, the oil pump pumps oil into the oil chamber 37, so that the hydraulic oil pushes the friction block 38 to move upward, so that the top of the friction block 38 abuts against the top wall of the limiting groove 34, the bottom of the hydraulic friction member 36 abuts against the bottom wall of the limiting groove 34, and the side wall of the hydraulic friction member 36 abuts against one end side wall, realizing the fixation of the threaded tie rod 30, avoiding the axial movement of the threaded tie rod 30 caused by typhoon pulling, reducing the friction between the threaded tie rod 30 and the threaded sleeve 20, and ensuring the service life.

[0052] It should be noted that the threaded tie rod 30 and the threaded sleeve 20 are in threaded fit at both ends of the threaded sleeve 20. When a typhoon impacts the rope, it is easy to cause the rope to pull the threaded tie rod 30 and the threaded sleeve 20 to rub against each other, and it is easy to cause the threaded fit position to bend or even break. Therefore, the two fixing components are symmetrically arranged on the outer peripheral surface of the threaded sleeve 20 and are respectively located at both ends of the threaded sleeve 20, forming a full-wrap constraint on the threaded fit section of the threaded sleeve 20 and the threaded tie rod 30, significantly improving the overall bending stiffness of the threaded fit part, making the axial load evenly distributed on the inner wall of the threaded sleeve 20, avoiding the risk of plastic deformation or fracture caused by local stress concentration, increasing the impact resistance against typhoons, and improving the service life of the device.

[0053] As Figure 3 and Figure 11As shown in the figure, the driving component includes: a reduction motor 13, a rotating shaft 14, and a reduction gear 15. Support plates 16 are provided on two outer walls of the reduction motor 13, and the support plates 16 are fixedly connected to the inner ring surface of the cylinder 10. The rotating shaft 14 is provided at the output end of the reduction motor 13, and the rotating shaft 14 penetrates through one end face of the cylinder 10. The reduction gear 15 is provided at the end of the rotating shaft 14, and the reduction gear 15 meshes with the first toothed ring 21. Therefore, when it is necessary to tighten the rope, the reduction motor 13 will drive the rotating shaft 14 to rotate, and the rotation of the rotating shaft 14 drives the reduction gear 15 to rotate. Since the reduction gear 15 meshes with the first toothed ring 21, the rotation of the reduction gear 15 drives the first toothed ring 21 and the threaded sleeve 20 to rotate. Thus, the threaded sleeve 20 and the threaded rod 30 cooperate with each other to achieve the effect of automatically tightening or loosening the rope, reducing the workload of manual labor and improving the fixing efficiency of the entire large-scale machinery.

[0054] As Figures 12 to 13 shown in the figure, the slip detection component includes: a detection ring 70 and a contact head 75. The detection ring 70 is sleeved on the outer peripheral surface of the threaded sleeve 20, and there are two detection rings 70. Fixing plates 73 are provided on the inner ring surfaces of the plurality of detection rings 70. The contact head 75 is provided on one outer wall of the fixing plate 73. Fixing blocks 71 are provided on the outer peripheral surface of the detection ring 70, and the fixing blocks 71 are symmetrically arranged on the outer peripheral surface of the threaded sleeve 20. Threaded holes 72 are provided in the fixing blocks 71. A bidirectional lead screw 81 is provided on the inner wall of the cylinder 10, and the bidirectional lead screw 81 is threadedly connected to the threaded holes 72. A motor 80 is provided at one end of the bidirectional lead screw 81. Lubricating mechanisms 90 are provided on two end faces of the cylinder 10, and the lubricating mechanisms 90 are located above the threaded engagement portion of the threaded sleeve 20 and the threaded rod 30. The lubricating mechanisms 90 are connected to the controller in the control box.

[0055] When detecting the fit degree of the threaded sleeve 20 and the threaded rod 30, first, the driving component drives the threaded rod 30 to move to both sides. While moving, the motor 80 drives the bidirectional lead screw 81 to rotate, and the rotation of the bidirectional lead screw 81 drives the detection ring 70 to move, so that the two detection rings 70 respectively follow the corresponding threaded rods 30 to move. When the cooperation between the threaded rod 30 and the threaded sleeve 20 is not smooth, it will cause a sudden change in the speed of the threaded rod 30 or jamming. At this time, the end of the threaded rod 30 will contact the contact head 75 on the detection ring 70. There is a pressure sensor at the bottom of the contact head 75. The information is detected by the pressure sensor and fed back to the control box. The control box controls the lubricating mechanism 90 to accurately lubricate the threaded sleeve 20 and the threaded rod 30, thus avoiding waste of lubricating oil. At the same time, the slip detection component can help personnel quickly determine the position with excessive wear and improve the maintenance efficiency.

[0056] As shown in Figures x to x, first joints 60 and second joints 61 are respectively arranged at both ends of the threaded tie rod 30. Both the first joint 60 and the second joint 61 are U-shaped, and there are openings at the upper part. The rope is placed in the U-shaped groove and connected through a pin. A pressure sensor 63 is arranged at the connection between the first joint 60 and the threaded tie rod 30. The pressure sensor 63 is electrically connected to the control box. In this embodiment, the electrical connection is realized through a wire. The pressure sensor 63 enables the device to reach the required pre-tightening force during braking, can quickly and stably tighten the device, and plays a very good protective role for the transmission components. U-shaped fasteners 33 are arranged on the outer walls of one sides of the first joint 60 and the second joint 61. Guide rods 31 are arranged on the outer walls of both ends of the cylinder body 10. The guide rods 31 correspond to the U-shaped fasteners 33 one by one, and the U-shaped fasteners 33 are slidably matched with the guide rods 31 to play a guiding role for the translational movement of the threaded tie rod 30.

[0057] A nut 22 is fixedly arranged on one end face of the first toothed ring 21, and the nut 22 is also threadedly connected to the threaded tie rod 30. When the electronic control element fails, manually disengage the reduction gear 15 from meshing with the first toothed ring 21, and then manually hold the nut 22 and rotate the nut 22 manually to rotate the threaded sleeve 20 manually to control the tightening or loosening of the ropes at both ends.

[0058] As shown in Figures x to x, an electrical connection module 19 is arranged on the outer wall of the cylinder body 10. The electrical connection module 19 is connected to the electrical control cabinet. The electrical control cabinet can provide power for the drive assembly and the control box. As needed, one control box can also control multiple cable mechanisms at the same time. When the cable is locked, first, after the electrical control cabinet is powered on, operate the control knob switch of the control box to the "control on" position, and operate the "cable tightening" button. At this time, multiple cable mechanisms work simultaneously to perform the tightening action. When each cable mechanism is tightened to the set value of each pressure sensor 63, the action stops. At this time, the cable has completed the tightening action, and the tightening indicator light of the control box lights up; when the cable is released, operate the "cable release" button of the control box. At this time, multiple cable mechanisms work simultaneously to perform the release action. When each cable mechanism is released to the in-place limit, the action stops. At this time, the cable has been released. When it is necessary to operate a single cable mechanism, the "control" knob switch of the control box needs to be turned to the "control off" position. At this time, the cable can be controlled separately through the control box, improving the efficiency of fixing and locking the entire large-scale machinery and reducing the manual workload.
