A guide rail structure for a ship crane

Abstract

The present invention belongs to the technical field of cranes, and discloses a guide rail structure for a ship crane, which includes two support components; a stay cable component; two sets of connection components; a slide rail component; a drive component and an auxiliary component. By installing the newly designed auxiliary component, the lifting structure hangs and hoists the heavy object, and before starting, the auxiliary component is flexibly driven according to the position where the heavy object is hoisted. If the heavy object is on the front side of the slide rail component, the first motor can be driven, and the lead screw is driven to rotate counterclockwise through the bevel gear set, so that the moving plate moves backward in the track groove. At this time, the two sets of third springs on the front side will be stretched, and the two sets of third springs on the back side will contract. In this way, the first guide rail on the front side will receive a stronger pulling force, solving the problem that the traditional guide rail structure uses hard connection, and the connection strength on both sides of the horizontal position is not adjustable, which may cause the negative effects of loosening and bending of the guide rail frame connection after multiple hoistings.

Description

Technical Field

[0001] The invention belongs to the technical field of cranes, and particularly relates to a guide rail structure for a ship crane. Background Art

[0002] A ship crane is an important mechanical device installed on a ship for loading, unloading and transporting goods. It is mainly used for the transfer of goods between ships. The guide rail of the crane is a series of products dedicated to the running track of the crane, mainly made of high-strength steel. This kind of guide rail has the characteristics of high precision, high rigidity and high durability, and can withstand various loads and stresses during the operation of the crane;

[0003] However, when actually lifting goods, the lifting point and the landing point of the goods will not be the central position of the crane. Therefore, when the moving component runs on the crane, the gravity degrees on both ends of the guide rail frame are different. Especially when the ship is sailing, the base of the crane is not completely horizontal at this time, and the offset force situation is more obvious. The traditional guide rail structure adopts hard connection, and the connection strength on both sides of the horizontal position is not adjustable. After multiple liftings, it may cause negative effects such as loose connection and bending of the guide rail frame. Summary of the Invention

Two grooves are formed in the inner side of the top of the gantry.

[0008] Preferably, the stay cable assembly includes two hollow blocks. The two hollow blocks are fixedly installed on the left and right sides of the gantry.

[0011] Preferably, the drive assembly includes two second motors. The two second motors are fixedly installed on the top of the second guide rail and are symmetrically installed.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention is equipped with a newly designed auxiliary component. When the heavy object is on the front side of the slide rail component, the first motor is driven, and the lead screw is driven to rotate counterclockwise through the bevel gear set, so that the moving plate can move backward in the track groove.

[0015] 2. The present invention is equipped with a connection component and a diagonal tension component in cooperation. When the equipment starts and stops, affected by the inertia of the vertically suspended heavy object, the first torsion bar will be forced to rotate a certain angle in the groove and then reset, and the second torsion bar will rotate a certain angle in the elliptical block and then reset. The first torsion bar will be forced to rotate a certain angle in the groove and then reset, and the second torsion bar will rotate a certain angle in the elliptical block and then reset. The steel cable will move up and down in the hollow block, compressing and resetting the second spring to offset the force of longitudinal movement.

[0016] 3. The present invention is equipped with a support component with a tapered block. Through the structure of the tapered block and the first spring, it is ensured that the crane can maintain stability under different working conditions. The tapered block will swing back and forth under the traction of the first spring according to the force situation and then reset, offsetting the lateral force, thereby reducing the damage to the mechanical structure caused by inertia.

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 6 shown, the embodiment of the present invention provides a guide rail structure for a ship crane, including two support components 1. Stay cable components 2 are fixedly installed on both sides of the two support components 1. It also includes

[0026] a linkage hoisting guide rail mechanism, which includes two groups of connection components 3. The two groups of connection components 3 are both movably hinged to the tops of the two support components 1. The bottoms of the two groups of connection components 3 are fixedly connected with a slide rail component 5. A drive component 6 is fixedly installed on the top of the slide rail component 5;

[0027] an auxiliary component 4. The auxiliary component 4 is fixedly installed on the tops of the two support components 1. The auxiliary component 4 includes two track grooves 41. A lead screw 42 is rotatably installed in the right track groove 41. The front end of the lead screw 42 is fixedly connected with a bevel gear set 43. The bevel gear set 43 is fixedly connected with a first motor 44 in the vertical direction. A moving plate 45 is threadedly connected to the outer edge of the lead screw 42. The right side of the moving plate 45 is movably clamped inside the left track groove 41. Two fixed blocks 46 are fixedly installed on the top of the moving plate 45. Two third springs 47 are movably hinged to the left and right sides of the two fixed blocks 46. The ends of the four groups of third springs 47 are all fixedly connected with rotating columns 48;

[0028] When the heavy object is on the front side of the sliding rail assembly 5, drive the first motor 44. The lead screw 42 is driven to rotate counterclockwise through the bevel gear set 43, so that the moving plate 45 can move backward in the track groove 41. At this time, the two sets of third springs 47 on the front side will be stretched, and the two sets of third springs 47 on the back side will contract. In this way, the first guide rail 51 on the front side will receive a stronger pulling force, solving the problem that the traditional guide rail structure uses hard connections and the connection strength on both sides in the horizontal position is non-adjustable. After multiple liftings, it may cause negative effects such as loose connection and bending of the guide rail frame;

[0029] Among them, the support assembly 1 includes two fixed seats 11. The bottoms of the two fixed seats 11 are elastically connected with first springs 12. The bottoms of the two first springs 12 are fixedly connected with conical blocks 13. A gantry 14 is fixedly installed on the tops of the two fixed seats 11. Two grooves 15 are opened on the inner side of the top of the gantry 14;

[0030] Through the structure of the conical block 13 and the first spring 12, it is ensured that the crane can maintain stability under different working conditions. The conical block 13 will swing back and forth and then reset under the traction of the first spring 12 according to the force condition, offsetting the lateral force, thereby reducing the damage to the mechanical structure caused by inertia;

[0031] Among them, the stay cable assembly 2 includes two hollow blocks 21. The two hollow blocks 21 are fixedly installed on the left and right sides of the gantry 14. The interiors of the two hollow blocks 21 are elastically connected with second springs 22. Steel cables 23 are fixedly connected to the middle positions of the two second springs 22. The tails of the two steel cables 23 are movably hinged with fixed rods 24;

[0032] The fixed rod 24 is fixed at a position far from the gantry 14, so that the steel cable 23 can reach the maximum range and can realize lateral traction. Affected by the inertia of the vertically suspended heavy object, the steel cable 23 will move up and down in the hollow block 21, compressing and resetting the second spring 22, thereby offsetting the longitudinal movement;

[0033] Among them, the connection assembly 3 includes two first torsion bars 31. The two first torsion bars 31 are movably hinged in the two grooves 15. Connecting rods 32 are fixedly connected to the bottoms of the two first torsion bars 31. Second torsion bars 33 are fixedly connected to the bottoms of the two connecting rods 32.

Fixed strips 36 are fixedly connected to the tails of the two bent rods 35;

[0034] When the equipment starts and stops, affected by the inertia of the vertically suspended heavy object, the first torsion bar 31 will rotate a certain angle under force in the groove 15 and then reset. The second torsion bar 33 will rotate a certain angle in the oval block 34 and then reset, offsetting the longitudinal moving force;

[0035] Among them, the slide rail assembly 5 includes two first guide rails 51. The two first guide rails 51 are fixedly installed on the inner sides of the two gantry frames 14. Guide rods 52 are fixedly connected to the outer sides of the two first guide rails 51. A round hole block 53 is slidably sleeved on the outer edges of the two guide rods 52. A second guide rail 54 is fixedly connected to the bottom of the two round hole blocks 53. Two sets of driven wheels 55 are fixedly installed on the top of the second guide rail 54. A U-shaped block 56 is movably installed at the bottom of the second guide rail 54. Two electric guide wheels 57 are installed through the U-shaped block 56, and both of the two electric guide wheels 57 are movably clamped in the second guide rail 54;

[0036] During the movement, the round hole block 53 will slide on the outer edge of the guide rod 52 to play a guiding role on the other side. When the second guide rail 54 moves, the two sets of driven wheels 55 and the rotating wheels 65 will firmly clamp the entire second guide rail 54 on the two first guide rails 51;

[0037] Among them, the driving assembly 6 includes two second motors 61. The two second motors 61 are both fixedly installed on the top of the second guide rail 54 and are symmetrically installed. Output shafts of the two second motors 61 are fixedly connected with first gears 62. Second gears 63 are meshed with the outer edges of the two first gears 62. Rotating shafts of the two second gears 63 are fixedly connected with transmission shafts 64. Rotating wheels 65 are fixedly connected to both ends of the two transmission shafts 64; Four groups of rotating columns 48 are fixedly installed on the tops of the two first guide rails 51. The two sets of driven wheels 55 are both movably clamped in the first guide rail 51. The two sets of rotating wheels 65 are both movably clamped in the first guide rail 51;

[0038] When the two second motors 61 drive the second gears 63 to rotate clockwise through the first gears 62, the second guide rail 54 can move horizontally to the right on the first guide rail 51. When the two second gears 63 rotate counterclockwise, it will drive the second guide rail 54 to move horizontally to the left on the first guide rail 51.

[0039] Working principle:

[0040] When using the present invention, first install the lifting structure at the bottom of the U-shaped block 56, fix the fixing rod 24 at a position far from the gantry frame 14, and make the steel cable 23 reach the maximum range to achieve lateral pulling. Then, the electric guide wheels 57 can be driven to drive the U-shaped block 56 to move longitudinally on the second guide rail 54. When the two second motors 61 drive the second gears 63 to rotate clockwise through the first gears 62, the second guide rail 54 can move horizontally to the right on the first guide rail 51. When the two second gears 63 rotate counterclockwise, it will drive the second guide rail 54 to move horizontally to the left on the first guide rail 51. When the second guide rail 54 moves, the two sets of driven wheels 55 and the rotating wheels 65 will firmly clamp the entire second guide rail 54 on the two first guide rails 51;

[0041] After the above operations, the lifting structure can be moved to any position on the bottom surface of the device. Hang and lift the heavy object, and flexibly drive the auxiliary component 4 according to the position where the heavy object is lifted before starting. If the heavy object is on the front side of the slide rail component 5, drive the first motor 44. The bevel gear set 43 drives the lead screw 42 to rotate counterclockwise, so that the moving plate 45 can move backward in the track groove 41. At this time, the two groups of third springs 47 on the front side will be stretched, and the two groups of third springs 47 on the back side will contract. In this way, the first guide rail 51 on the front side will receive a stronger pulling force. Then start the driving component 6 and the electric guide wheel 57, and hoist the heavy object to the designated area and unload it.

[0042] During the movement, the round hole block 53 will slide on the outer edge of the guiding rod 52 to play a guiding role on the other side. Moreover, when the device starts and stops, affected by the inertia of the vertically suspended heavy object, the first torsion bar 31 will rotate by a certain angle and reset under force in the groove 15. The second torsion bar 33 will rotate by a certain angle and reset in the elliptical block 34. The steel cable 23 will move up and down in the hollow block 21, compressing and resetting the second spring 22, so as to offset the force of longitudinal movement. The conical block 13 will swing back and forth and reset under the traction of the first spring 12 according to the force condition to offset the lateral force, thereby reducing the damage of inertia to the mechanical structure. So far, the working process ends.
