Technical Field

[0001] This utility model relates to the field of grab bucket technology, and in particular to a four-fold wireless remote-controlled multi-lobed grab bucket. Background Technology

[0002] Grab buckets are mainly used in ship cranes. Due to height limitations, the grab bucket wire rope often adopts a three-fold ratio structure. When used in port gantry cranes and ship unloaders, the three-fold ratio grabbing force is insufficient and the grabbing force needs to be further increased. Summary of the Invention

[0003] The purpose of this invention is to provide a four-fold wireless remote-controlled multi-lobed grab bucket.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A 4x wireless remote-controlled multi-lobed grab bucket, characterized by comprising a balance frame, a steel wire rope, an upper support beam, a sliding seat, a lower support beam, and a six-lobed bucket body. The upper support beam is hexagonal, and the balance frame is fixed to the upper support beam. The six sides of the upper support beam are connected to the six-lobed bucket body by six support rods. The upper end of the bucket body is hinged to the outer edge of the lower support beam. A hydraulic cylinder is fixedly installed at the center of the upper end of the lower support beam. A hydraulic system and a remote control system are fixedly installed on the side of the upper end of the lower support beam. An oil tank is fixedly installed at the lower end of the lower support beam. The oil pipe of the hydraulic cylinder is connected to the valve block of the hydraulic system. The hydraulic oil in the grab bucket cylinder is switched by a solenoid valve. When the oil tank is connected, the solenoid valve is controlled by a remote control system to switch directions. The inner side of the sliding seat is connected to the hydraulic cylinder through a sleeve block. The hydraulic cylinder can lock or release the sleeve block of the sliding seat. The sleeve block limits the downward movement range of the hydraulic cylinder. The upper support beam is equipped with an upper pulley. The front and rear sides of the sliding seat are respectively equipped with a first lower pulley and a second lower pulley. The upper end of the upper support beam is equipped with a rope guide device. One end of the wire rope is suspended on the balance frame. The other end of the wire rope passes through the rope guide device from one end of the upper support beam to the first lower pulley, then upwards to the upper pulley, then downwards to the second lower pulley, and finally upwards to the other end of the upper support beam for fixation.

[0006] Furthermore, the upper end of the support rod is rotatably connected to the upper support beam via a pin, and the lower end of the support rod is rotatably connected to the bucket body via a pin.

[0007] Furthermore, one end of the wire rope is suspended on the balance frame via a small shackle.

[0008] Furthermore, the other end of the wire rope is fixed to the upper bearing beam by a wedge and a fixed wedge sleeve.

[0009] Furthermore, a large shackle is fixedly provided at the upper end of the balance frame, and a long ring is fitted onto the large shackle, which is connected to the hook of the gantry crane.

[0010] This invention improves upon the three-fold ratio of the grab bucket wire rope by adopting a parallel, U-shaped rope threading method to provide a four-fold ratio remote-controlled grab bucket, which greatly improves the grabbing force, makes the overall force distribution of the grab bucket more stable and reliable, and allows a single grab bucket to meet the needs of grabbing different species, thereby reducing costs.

[0011] This utility model features a six-lobed grab structure, which enables the grab to achieve greater gripping force and has a certain demolition capability. Attached Figure Description

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This embodiment discloses a four-fold wireless remote-controlled multi-lobed grab bucket, such as... Figure 1 As shown, it includes a balance frame 1, wire rope 2, upper support beam 4, sliding seat 6, lower support beam 7, and six-lobed bucket body 8, as follows. Figure 2 As shown, a large shackle 12 is fixedly installed at the upper end of the balance frame 1. The large shackle 12 is fitted with a long ring 13, which is connected to the hook of the gantry crane.

[0023] like Figure 3 As shown, the upper support beam 4 is hexagonal, the balance frame 1 is fixed on the upper support beam 4, and the six sides of the upper support beam 4 are connected to the six-lobed bucket body 8 by six support rods 5. The upper end of the support rod 5 is rotatably connected to the upper support beam 4 by a pin, and the lower end of the support rod 5 is rotatably connected to the bucket body 8 by a pin. The upper end of the bucket body 8 is hinged to the outer edge of the lower support beam 7.

[0024] A hydraulic cylinder 9 is fixedly installed at the center of the upper end of the lower support beam 7. A hydraulic system 10 and a remote control system 11 are fixedly installed on the side of the upper end of the lower support beam 7. An oil tank is fixedly installed at the lower end of the lower support beam 7. The oil pipe of the hydraulic cylinder 9 is connected to the valve block of the hydraulic system 10. The hydraulic oil in the grab cylinder 9 is switched to the oil tank through a solenoid valve. The solenoid valve is controlled by the remote control system 11 to switch.

[0025] The inner side of the sliding seat 6 is fitted onto the hydraulic cylinder 9 via a sleeve block. The sliding seat 6 is driven to move up and down by the wire rope 2. The hydraulic cylinder 9 can lock or release the sleeve block of the sliding seat 6. At the same time, the hydraulic cylinder 9 is limited by the lower movement range of the sleeve block of the sliding seat 6, that is, the lower movement range of the lower bearing beam 7 is limited.

[0026] The upper support beam 4 is equipped with an upper pulley 16, and the front and rear ends of the sliding seat 6 are respectively equipped with a first lower pulley 17 and a second lower pulley 18. The upper end of the upper support beam 4 is equipped with a guide rope device 3, such as... Figure 4 As shown, one end of the wire rope 2 is suspended on the balance frame 1, and the other end of the wire rope 2 passes through the guide rope device 3 from one end of the upper support beam 4 to the first pulley 17, then up to the upper pulley 16, then down to the second pulley 18, and finally up to the other end of the upper support beam 4 for fixation.

[0027] One end of the wire rope 2 is suspended on the balance frame 1 via a small shackle 19, and the other end of the wire rope 2 is fixed to the upper bearing beam 4 via a wedge 15 and a fixed wedge sleeve 14. Figure 4 As shown, the other end of the wire rope 2 is first wound counterclockwise around the wedge 15, and then the fixed wedge sleeve 14 is used to press down and clamp the wire rope 2 and the wedge 15. The structure of the wedge 15 and the fixed wedge sleeve 14 makes it easy to disassemble and install.

[0028] In this embodiment, when the grab bucket is in use, the sliding seat 6 and the lower support beam 7 are locked by the hydraulic cylinder 9, and the steel wire rope 2, combined with the pulley block, drives the lower support beam 7 and the sliding seat 6 to move upward synchronously with a force of four times the ratio to close the six-lobed bucket body 8 to grab the goods.

[0029] When the grab reaches the designated unloading position, the hydraulic oil in the grab cylinder 9 is switched to the oil tank through the solenoid valve. The cylinder 9 extends to release the sleeve block of the sliding seat 6, the lower support beam 7 disengages from the sliding seat 6 and slides down, and the six-lobed bucket body 8 flips open.

[0030] The switching of the solenoid valve is controlled by a remote controller. The remote controller and receiver together form the remote control system 11 of the grab bucket. Through the combination of the remote control system 11 and the hydraulic system 10, the bucket body 8 can be opened remotely.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
