[0020] 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.

[0021] This embodiment discloses a four-fold wireless remote-controlled dual-lobed grab bucket, such as... Figure 1 As shown, it includes a balance frame 1, a wire rope 2, an upper support beam 4, a sliding seat 6, a lower support beam 7, and a grab bucket 8. The upper support beam 4 is arranged along the front-to-back direction, and the balance frame 1 is fixed on the upper support beam 4, as shown. 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.

[0022] The upper support beam 4 and the grab bucket 8 are connected by a support rod 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 grab bucket 8 by a pin. The lower support beam 7 is installed on the upper end of the grab bucket 8 in the front-back direction. The lower support beam 7 is rotatably connected to the double petals of the grab bucket 8. When the lower support beam 7 moves down, the double petals of the grab bucket 9 flip open. When the lower support beam 7 moves up, the double petals of the grab bucket 9 flip close.

[0023] like Figure 3 As shown, hydraulic cylinders 9 are fixedly installed on the front and rear sides of the lower support beam 7. The upper end of the sliding seat 6 is fitted onto the hydraulic cylinder 9 through a set of symmetrical sleeve blocks. An oil tank, a hydraulic device 10 and a remote control device 11 are also fixedly installed on the lower support beam 7. The oil pipe of the upper cavity of the hydraulic cylinder 9 is connected to the valve block of the hydraulic device 10, and the oil pipe of the lower cavity of the hydraulic cylinder 9 is connected to the oil tank.

[0024] The sliding seat 6 is driven to move up and down by the steel 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 sleeve block of the sliding seat 6 to move down within a certain range, that is, to limit the downward movement range of the lower bearing beam 7.

[0025] 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.

[0026] 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.

[0027] In this embodiment, 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 double petals of the grab bucket 8 to grab the goods.

[0028] When the grab bucket 8 reaches the designated unloading position, the hydraulic oil in the hydraulic cylinder 9 is switched to the oil tank through the solenoid valve. The hydraulic cylinder 9 extends to release the sleeve of the sliding seat 6, and the lower support beam 7 disengages from the sliding seat 6 and slides down, so that the grab bucket 8 opens its double petals to unload the cargo.

[0029] 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 grab bucket 8 can be opened remotely.

[0030] 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.
