A sway-reducing and stabilizing device for crane sling

Abstract

The present invention relates to the field of crane equipment, and in particular to a sway reduction and stabilization device for a crane hoist. In view of the problem in the prior art that a steel wire rope will inevitably shake during the speed regulation of a trolley, a sway reduction and stabilization device for a crane hoist is provided. Two first auxiliary ropes that are cross-arranged with each other are respectively arranged on the front and rear sides between a stabilization plate and a mounting plate. The lower ends of the first auxiliary ropes are respectively fixedly connected to fixed plates. When the crane trolley drives the hoist to move, the fixed plates are pulled mutually by the first auxiliary ropes that are cross-arranged with each other. Under the action of a two-way ratchet self-locking structure, while ensuring that the first auxiliary rope can be retracted and released by a first winding wheel, the pulling force from the first auxiliary rope cannot drive the first winding wheel to rotate, so that the first auxiliary rope can effectively maintain traction, reduce the shaking of the hoist during movement, and enhance the stability of the hoist during movement.

Description

Technical Field

[0002] In modern industry, construction, ports, mining and other fields, cranes are important mechanical equipment for lifting and moving heavy objects, and their stability and safety are of vital importance. During the start, stop, acceleration and deceleration of the crane, due to speed changes, external interference factors (such as wind force) and imprecise operation control, the spreader often swings left and right or forward and backward. This swing not only reduces work efficiency and affects the efficiency of lifting and loading and unloading, but also increases the labor intensity of operators, causing damage to goods or accidental injury to operators, causing safety hazards. During the operation of the crane, in order to avoid the spreader from shaking during operation, the travel speed of the crane trolley can be adjusted accordingly according to the shaking of the spreader to offset the shaking during construction. However, in actual operation, it is necessary to accumulate skilled operating techniques, and the wire rope will inevitably shake during the speed adjustment of the trolley, which is not conducive to the operation and training of construction personnel.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0031] like Figure 1-14 As shown, the present invention provides a sway reduction and stabilization device for a crane sling, comprising a crane trolley 1, a sling 2, and a steel wire rope 9 connected between the crane trolley 1 and the sling 2. When the crane is in operation, the crane trolley 1 drives the sling 2 to move by moving, and is used to transport goods. When the sling 2 is hoisting goods, the steel wire rope 9 drives the goods to be lifted and moved. A mounting plate 3 is fixedly connected to the lower side of the crane trolley 1, a fixing plate 5 is fixedly connected to the upper end of the sling 2, a stabilizing plate 4 is connected to the upper side of the fixing plate 5, and an elastic buffer component is installed between the fixing plate 5 and the stabilizing plate 4, such as Figure 2 and Figure 6As shown, two mutually cross-arranged first auxiliary ropes 19 are respectively arranged on the front and rear sides between the stabilizing plate 4 and the mounting plate 3, and the lower ends of the first auxiliary ropes 19 are respectively fixedly connected to the fixing plates 5. When the crane trolley 1 drives the sling 2 to move, the mutually cross-arranged first auxiliary ropes 19 are used to pull the fixing plates 5 to each other, so as to reduce the shaking of the sling 2 during movement and enhance the stability of the sling 2 during movement. The front and rear sides of the left and right sides of the lower end of the mounting plate 3 are respectively rotatably connected with first winding wheels 18 for winding up the corresponding first auxiliary ropes 19. The front and rear correspondingly arranged first winding wheels 18 are coaxially fixedly connected. When the sling 2 is lifted or lowered, the first winding wheels 18 can rotate synchronously to wind and release the first auxiliary ropes 19, so as to avoid the first auxiliary ropes 19 being too scattered, and to maintain the tension of the first auxiliary ropes 19 and the traction effect of the first auxiliary ropes 19. The lower end of the mounting plate 3 is fixedly connected to a fixing frame 10, and the left and right sides of the front and rear ends of the fixing frame 10 are respectively provided with pressure wheel assemblies, which cooperate with the wire rope 9. When the wire rope 9 is working, power is transmitted through the pressure wheel assembly, and the front ends of the first winding wheels 18 on the front side are respectively connected with two-way ratchet self-locking structures, and a spline transmission assembly is connected between the two-way ratchet self-locking structure and the pressure wheel assembly. When the sling 2 is lifted or lowered, the wire rope 9 is in a moving state, and the power is transmitted to the sling 2 through the spline transmission assembly through the cooperation of the wire rope 9 and the pressure wheel assembly. The two-way ratchet self-locking structure drives the first winding wheel 18 to rotate. Under the action of the two-way ratchet self-locking structure, the forward and reverse rotations of the first winding wheel 18 have a self-locking effect, which does not affect the winding and releasing of the first auxiliary rope 19 of the first winding wheel 18, and the tension from the first auxiliary rope 19 cannot drive the first winding wheel 18 to rotate, so that the first auxiliary rope 19 can effectively maintain the traction force. When the stabilizing plate 4 shakes to one side, the first auxiliary rope 19 on the other side can pull the stabilizing plate 4 to reduce the shaking of the stabilizing plate 4.

[0032] like Figure 4 and Figure 5 As shown, the pressing wheel assembly includes a mounting seat 11 fixedly connected to the front and rear sides of the left and right ends of the mounting plate 3, and an upper pressing wheel 14 and a lower pressing wheel 15 are respectively arranged on the upper and lower sides of the mounting seat 11. The upper pressing wheel 14 and the lower pressing wheel 15 are pressed against the surface of the wire rope 9 respectively. When the wire rope 9 moves, the upper pressing wheel 14 and the lower pressing wheel 15 can be driven to rotate under the action of the friction force with the upper pressing wheel 14 and the lower pressing wheel 15; The front and rear ends of the upper pressing wheel 14 are respectively connected to the upper clamping plate 12 for coaxial rotation, and the front and rear ends of the lower pressing wheel 15 are respectively connected to the lower clamping plate 13 for coaxial rotation. The inner ends of the upper clamping plate 12 and the lower clamp are respectively connected to the mounting seat 11 for rotation. The surfaces of the upper clamping plate 12 and the lower clamping plate 13 which are arranged correspondingly above and below are commonly fixedly connected with a tension spring 17. Under the action of the tension spring 17, the upper and lower corresponding upper clamping plates 12 and the lower clamping plates 13 have a traction force to swing inward, so that the upper pressing wheel 14 and the lower pressing wheel 15 can always maintain a close connection with the wire rope 9, ensuring the friction between the upper pressing wheel 14 and the lower pressing wheel 15 and the wire rope 9 respectively, and when the wire rope 9 shakes, the tension spring 17 can act on the surface of the wire rope 9 through its own elastic tension, thereby assisting the wire rope 9 to reduce the shaking.

[0033] Further, such as Figure 8 , Fig. 9 and Fig.10 As shown, the bidirectional ratchet self-locking structure includes a ratchet 27 coaxially arranged on the front side of the first winding wheel 18, a right-angle plate 38 is fixedly connected to the surface of the ratchet 27, the upper end of the right-angle plate 38 is fixedly connected to the mounting plate 3, and the ratchet 27 is fixedly connected to the mounting plate 3. When the first winding wheel 18 reels the first auxiliary rope 19, braking is achieved through the ratchet 27; A second transmission rod 39 is fixedly connected to the front end of the first winding wheel 18 on the front side, and the second transmission rod 39 is coaxially rotatably connected to the ratchet 27. A driven plate 30 is rotatably connected to the surface of the second transmission rod 39, and the driven plate 30 is coaxially rotatably connected to the inner side of the ratchet 27. The circumferential surface of the driven plate 30 is respectively connected to a plurality of ratchet plates 31 in radial sliding manner, and the inner ends of the ratchet plates 31 are respectively meshed with the ratchet 27, and meshing springs 37 are respectively fixedly connected between the ratchet plate 31 and the driven plate 30, and the second meshing springs 37 are used to push the ratchet plate 31 to mesh with the ratchet 27 to maintain a one-way braking effect; A first annular brake pad 32 is provided on the front side of the driven plate 30, and the first annular brake pad 32 is axially slidably connected to the surface of the second transmission rod 39, and an adjusting cylinder 34 is threadedly connected to the front end of the second transmission rod 39, and the screwing direction of the adjusting cylinder 34 is the same as the direction in which the driven plate 30 can be driven to rotate under the meshing of the ratchet plate 31 and the ratchet wheel 27, and a second annular brake pad 35 capable of cooperating with the first annular brake pad 32 is fixedly connected to the rear end of the adjusting cylinder 34, and the second annular brake pad 35, the first annular brake pad 32 and the driven plate 30 are tightly fitted under the extrusion of the adjusting cylinder 34, and the transmission is transmitted through friction force, and the surface of the adjusting cylinder 34 is axially slidably connected to a transmission cylinder 36, and the front end of the transmission cylinder 36 is connected to the spline transmission assembly for transmission; when the transmission cylinder 36 When rotating, the adjusting cylinder 34 can be driven to rotate. When the adjusting cylinder 34 rotates and screws in, the first annular brake pad 32 is pressed toward the driven plate 30 through the second annular brake pad 35, so that the first annular brake pad 32, the second annular brake pad 35 and the driven plate 30 are kept in close connection. Then, the adjusting cylinder 34 can drive the driven plate 30 to rotate during the continuous rotation, and then the driven plate 30 is driven to move on the circumferential surface of the ratchet wheel 27 through the driven plate 30. Under the meshing of the ratchet plate 31 and the ratchet wheel 27, when the adjusting cylinder 34 rotates in the screwing direction, it can only drive the driven plate 30 to rotate in the direction of the first winding wheel 18 to reel in the first auxiliary rope 19. The first winding wheel 18 cannot be reversed, and then the first auxiliary rope 19 can achieve the traction of the fixed plate 5. When the sling 2 moves downward, the first winding wheel 18 needs to be rotated to release the first auxiliary rope 19. At this time, the transmission cylinder 36 drives the adjustment cylinder 34 to rotate in the opposite direction. Since the driven plate 30 cannot be reversed under the meshing of the ratchet plate 31 and the ratchet wheel 27, when the adjustment cylinder 34 rotates in the opposite direction, it will rotate in the direction of rotation, so that the first annular brake pad 32, the second annular brake pad 35 and the driven plate 30 are no longer squeezed, and the friction force disappears. The first auxiliary rope 19 can be pulled downward under the action of gravity and drive the first winding wheel 18 to rotate in the opposite direction. It is worth noting that when the first winding wheel 18 rotates in the opposite direction, the second transmission rod 39 also rotates in the opposite direction. While driving the transmission rod in the opposite direction under the action of gravity, the adjusting cylinder 34 can be screwed in under the action of the threaded connection with the adjusting cylinder 34, thereby maintaining the friction between the first annular brake pad 32, the second annular brake pad 35 and the driven plate 30, so that the transmission rod keeps rotating at the same speed when the adjusting cylinder 34 rotates in the opposite direction, allowing the load on the first auxiliary rope 19 to decrease at the same speed as the rotation of the adjusting cylinder 34, so that when the adjusting cylinder 34 rotates in the opposite direction to reduce the pressure on the first annular brake pad 32, the second annular brake pad 35 and the driven plate 30, the load on the first auxiliary rope 19 causes the transmission rod to rotate at the same speed, and the adjusting cylinder 34 is driven to be screwed in under the action of the threaded connection between the transmission rod and the adjusting cylinder 34, so as to maintain the pressure on the first annular brake pad 32, the second annular brake pad 35 and the driven plate 30, so that the transmission rod will not exceed the rotation speed of the adjusting cylinder 34, thereby achieving a self-locking effect.

[0034] The upper and lower sides of the surface of the driven plate 30 are respectively provided with connecting grooves along the radial direction of the ratchet 27, and the inner ends of the ratchet plate 31 are respectively fixedly connected with connecting sliders, which are slidably connected to the connecting grooves. Under the action of the sliding connection between the connecting sliders and the connecting grooves, the ratchet plate 31 moves stably and maintains engagement with the ratchet 27. The engagement springs 37 are respectively arranged on the outside of the connecting sliders. Under the engagement of the ratchet plate 31 with the ratchet 27, the driven plate 30 can rotate in the direction of driving the first winding wheel 18 to wind the first auxiliary rope 19.

[0035] A plurality of second linkage protrusions 33 are evenly provided on the inner side of the first annular brake pad 32, and a plurality of second linkage grooves that slide with the second linkage protrusions 33 are evenly provided on the surface of the second transmission rod 39. Under the sliding cooperation between the second linkage grooves and the second linkage protrusions 33, the second annular pad can be displaced on the surface of the second transmission rod 39, and brake the second transmission rod 39 while the first annular brake pad 32 and the driven plate 30 maintain pressure; a plurality of first linkage protrusions 28 are evenly provided on the front end surface of the adjusting cylinder 34, and a plurality of first linkage grooves that slide with the first linkage protrusions 28 are evenly provided on the inner side of the transmission cylinder 36. Under the sliding cooperation between the first linkage grooves and the first linkage protrusions 28, the transmission cylinder 36 can not only drive the adjusting cylinder 34 to rotate, but also the adjusting cylinder 34 can move axially inside the transmission cylinder 36.

[0036] like Figure 7 As shown, the spline transmission assembly includes a spline cylinder 20 and a spline shaft 21 connected with a spline, the end of the spline shaft 21 away from the spline cylinder 20 is coaxially fixedly connected with a third transmission bevel gear 25, the front end of the first transmission rod 29 is coaxially fixedly connected with a fourth transmission bevel gear 26, and the third transmission bevel gear 25 is meshed with the fourth transmission bevel gear 26; A second transmission bevel gear 24 is coaxially fixedly connected to one end of the spline cylinder 20 away from the spline shaft 21, and a first transmission bevel gear 23 is coaxially fixedly connected to the front side of the upper pressing wheel 14, and the first transmission bevel gear 23 is meshed with the second transmission bevel gear 24; One end of the spline cylinder 20 and the spline shaft 21 are respectively rotatably connected with a coupling frame 22, and the other end of the coupling frame 22 is respectively rotatably connected with the corresponding first transmission rod 29 and the upper pressure wheel 14. When the wire rope 9 drives the upper pressure wheel 14 to rotate, the spline cylinder 20 can be driven to rotate through the meshing transmission of the first transmission bevel gear 23 and the second transmission bevel gear 24, and the third transmission bevel gear 25 can be driven to rotate through the spline connection between the spline cylinder 20 and the spline shaft 21, and then the third transmission bevel gear 25 and the fourth transmission bevel gear 25 are connected to the spline cylinder 20. The meshing transmission of the gear 26 drives the first transmission rod 29 to rotate, and when the first transmission rod 29 rotates, the first winding wheel 18 is driven to rotate through the two-way ratchet self-locking structure to retract and release the first auxiliary rope 19; and the spline cylinder 20 and the spline shaft 21 can not only transmit when rotating due to the spline connection, but the spline cylinder 20 can also move axially on the surface of the spline shaft 21, and the spline cylinder 20 can move on the surface of the spline shaft 21 when the upper clamping plate 12 swings, without affecting the transmission effect of the spline cylinder 20 and the spline shaft 21.
