DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figure 1As shown, a hydraulic grab bucket hanging plate includes a panel 1, a group of main load-bearing ribs 2 arranged on the panel 1, a cross hanging handle assembly 3 movably arranged on the main load-bearing ribs 2, a balance beam assembly 4 movably arranged on the cross hanging handle assembly 3, and a winding drum 5 arranged on the panel 1. The center of the panel 1 and the center of the main load-bearing ribs 2 are located on the same axis. The main load-bearing ribs 2 are welded to the middle position of the panel 1, and the winding drum 5 is welded to the middle position of the side of the panel 1 perpendicularly relative to the main load-bearing ribs 2. The balance beam, cross hanging handle and main load-bearing ribs 2 are connected by a pin 6, and the pin is fixed with a slotted nut. The slotted nut 10 is prevented from loosening by a cotter pin 8. The slotted nut 10 increases the contact area and prevents loosening through a nut gasket 9 and provides a smooth surface.

[0020] Panel 1 serves as the basic component of the hydraulic grab bucket's hanging plate. Panel 1 bears the weight of the entire hanging plate and the load generated during lifting. A group of main load-bearing ribs 2 are set on the panel 1, playing a key load-bearing and supporting role. Together with the panel 1, they constitute the main structure of the hanging plate, enhancing the overall stability and load-bearing capacity of the hanging plate. The cross handle assembly 3, which is movably set on the main load-bearing rib 2, is a key component connecting the hanging plate and the lifting equipment. It allows the hanging plate to be flexibly rotated and adjusted during the lifting process to adapt to lifting requirements at different angles and directions. The balance beam assembly 4, which is movably set on the cross handle assembly 3, plays a role in balancing and stabilizing the hanging plate. It can help to reasonably distribute and balance the load during the lifting process and prevent the hanging plate from tilting or being damaged due to uneven load. The reel 5 set on the panel 1 fixes the power cord on the reel 5 to avoid entanglement. It ensures safety and reliability during the lifting process and reduces safety hazards during use.

[0021] like Figure 2 As shown, the cross handle assembly 3 includes a straight ear plate 3.1, a round ear plate 3.2 provided at the upper end of the straight ear plate 3.1, and an anti-rotation baffle 3.3 provided at the bottom side of the straight ear plate 3.1 and the side of the round ear plate 3.2. The round ear plate 3.2 is connected to the main load-bearing rib plate 2 via a pin, and the round ear plate 3.2 is connected to the balance beam via a pin. During the grabbing process, the position and direction can be automatically adjusted as the grab bucket swings. The straight ear plate 3.1 can transfer the weight of the hanging board and the lifting load to the main load-bearing rib plate 2, and then distribute it to the entire hanging board structure. During the lifting process, the anti-rotation baffle 3.3 can prevent the straight ear plate 3.1 and the round ear plate 3.2 from rotating due to uneven force or external factors, thereby ensuring the stability and safety of the hanging board. Through the coordinated use of the straight ear plate 3.1, the round ear plate 3.2 and the pin shaft, the cross handle assembly 3 achieves a reliable connection with the main load-bearing rib 2 and the balance beam, and at the same time adjusts the lifting posture and angle according to actual needs, thereby improving the flexibility and adaptability of the lifting.

[0022] like Figure 3As shown, the balance beam assembly 4 includes a balance beam main board 4.3, balance beam ear plates 4.2 respectively arranged at both ends of the balance beam main board 4.3, and ear plate support plates 4.1 arranged at the ends of the balance beam ear plates 4.2. The balance beam main board 4.3 is connected to the round ear plates 3.2 of the cross handle assembly 3 by a pin. During the hoisting process, the balance beam main board 4.3 can bear the weight and hoisting load from the hanging plate and transfer it to the balance beam ear plates 4.2 at both ends. The balance beam main board 4.3 is connected to the round ear plates 3.2 of the cross handle assembly 3 by a pin, realizing the connection and transmission between the hanging plate and the hoisting equipment. In addition, a mounting hole for mounting a shaft sleeve 11 is opened on the balance beam main board 4.3. The mounting hole and the shaft sleeve 11 are interference fit. The shaft sleeve 11 is connected to the round ear plates 3.2 of the cross handle assembly 3 by a pin, so that the balance beam assembly 4 and the cross handle assembly 3 can swing. A through hole is provided on the balance beam ear plate 4.2, and the through hole is connected to the special hoisting mechanism of the crane through a pin shaft.

[0023] like Figure 4 As shown, panel 1 is provided with ribs 7, the end faces of which are perpendicularly connected to the sides of the primary load-bearing ribs 2. This perpendicular connection between ribs 7 and the sides of the primary load-bearing ribs 2 creates a more stable structural system. This connection effectively distributes and absorbs the weight and lifting load of the hanger panel, preventing deformation or damage to panel 1 due to excessive forces. The addition of ribs 7 significantly increases the structural strength and rigidity of the entire hanger panel, ensuring its stability and safety during installation.

[0024] The wire reel 5 includes two side panels 5.2 spaced apart on the panel 1 and a wire reel tube 5.1 disposed between the upper ends of the two side panels 5.2. The side panels 5.2 are disposed on the panel 1, and the end faces of the side panels 5.2 are vertically connected to the side faces of the main load-bearing ribs 2. The side panels 5.2 serve as the basic support structure of the wire reel 5 and are firmly connected to the panel 1, providing stable support for the wire reel tube 5.1. The wire reel tube 5.1 is the core component of the wire reel 5. The power cord is fixed to the wire reel tube 5.1. The wire reel 5 is positioned away from the fixed position of the balance beam. During hoisting, the power cord is kept away from the wire rope to avoid entanglement, thereby reducing potential safety hazards during use, making operation more convenient, and reducing the failure rate.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
