Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hydraulic wood-grabbing machinery, and more specifically, to a reinforced hydraulic wood grabber. BACKGROUND ART

[0002] The main existing forms of wood grabbers on the market are divided into single-cylinder hydraulic wood grabbers, double-cylinder hydraulic wood grabbers, and mechanical wood grabbers in terms of principle. Their structural forms are mainly hollow-shaped grab teeth, and their design purposes are mainly for grabbing wood.

[0003] After retrieval, the utility model patent with the publication number of CN220950856U discloses a double-link hydraulic rotary wood grabber, which includes a rotary table, a boom connecting body, a mounting seat, a left claw body and a right claw body, a left hydraulic cylinder and a right hydraulic cylinder. A claw body connecting body is provided at the bottom of the mounting seat, and hydraulic cylinder connecting bodies are provided on both sides. The two ends of the bottom of the claw body connecting body are respectively hinged to the left claw body and the right claw body. The left hydraulic cylinder connects the left claw body and the hydraulic cylinder connecting body on the left side, and the right hydraulic cylinder connects the right claw body and the hydraulic cylinder connecting body on the right side. Hinged connecting rods are provided on both sides of the mounting seat and between the left claw body and the right claw body. One end of the hinged connecting rod is hinged to the top of the left claw body, and the other end is hinged to the top of the right claw body. The structure of this patent is reasonable. There is a hinged connecting rod between the left claw body and the right claw body, which are interrelated during the working process. When the left hydraulic cylinder and the right hydraulic cylinder act on the left claw body and the right claw body respectively, it can ensure balance and the opening degree of the two claw bodies, which is beneficial to grabbing a large amount of wood. However, the above patent still has the following deficiencies: the widths of the left claw body and the right claw body are fixed, which is not convenient for stably supporting the grabbed wood. At the same time, the space inside the left claw body and the right claw body after closing is fixed, which is not convenient for stably grabbing the wood. For this reason, we propose a reinforced hydraulic wood grabber. CONTENTS OF THE UTILITY MODEL

A driving mechanism 6 is provided between every two claw bodies 4 and the triangular hanging bracket 2. An extrusion limiting mechanism 5 is provided on the triangular hanging bracket 2. Claw plates 7 are placed inside every two claw bodies 4. Threaded holes 8 are formed in the claw plates 7. Step holes 9 are formed in the claw bodies 4. An internal hexagonal bolt 10 is sleeved in the inner cavity of the step hole 9. The end of the internal hexagonal bolt 10 is threadedly installed into the inner cavity of the threaded hole 8.

[0026] Specifically, please refer to Figures 1 to 3 , The extrusion limiting mechanism 5 includes support plates 11 fixedly connected to both sides of the triangular hanging bracket 2. Springs 12 are fixedly connected to the bottom surfaces of the two support plates 11. A reinforcing plate 13 is fixedly connected to the bottom ends of the two springs 12. Two sliding rods 14 are fixedly connected to the top surface of the reinforcing plate 13. The top ends of the two sliding rods 14 are respectively movably sleeved on the tops of the support plates 11 and fixedly connected with limit seats 15.

[0027] In this embodiment, the reinforcing plate 13 is limited by the movable sleeve connection between the support plate 11 and the sliding rod 14, so that the reinforcing plate 13 can only move along the axial direction of the sliding rod 14.

[0028] Specifically, please refer to Figures 1 to 3 , The driving mechanism 6 includes an upper rotating bracket 17 fixedly connected to the end of the triangular hanging bracket 2 and a lower rotating bracket 16 fixedly connected to the outside of the two claw bodies 4. A rotating column 19 is fixedly sleeved between the two lower rotating brackets 16. A lower rotating seat 20 is rotatably connected to the middle of the rotating column 19. An upper rotating seat 18 is rotatably connected to the upper rotating bracket 17. A hydraulic cylinder 21 is fixedly installed at the end of the upper rotating seat 18. The output end of the hydraulic cylinder 21 is connected to the end of the lower rotating seat 20.

[0029] In this embodiment, the telescopic movement of the hydraulic cylinder 21 drives the claw body 4 to rotate, so as to grab the wood by the claw plate 7 on the claw body 4.

[0030] Specifically, please refer to Figure 1 , A plurality of mounting holes 22 are formed in the top surface of the mounting base 1.

[0031] In this embodiment, the log grapple is connected to the driving machine through the cooperation of the mounting holes 22 and screws.

[0032] Specifically, please refer to Figure 2 , The outer diameter of the threaded end of the internal hexagonal bolt 10 is equal to the inner diameter of the top end of the step hole 9.

[0033] In this embodiment, the stability of the hexagon socket head bolt 10 inserted into the stepped hole 9 is ensured, so as to ensure the stability of the installation of the hexagon socket head bolt 10 on the clamping plate 7.

[0034] Specifically, please refer to Figure 4 , a ramp opening 23 is provided at the bottom end of the clamping plate 7.

[0035] In this embodiment, the ramp opening 23 is used to facilitate the grasping of the wood.

[0036] Working principle: During use, first, the clamping plate 7 is installed on the claw body 4 through the cooperation of the threaded hole 8, the stepped hole 9 and the hexagon socket head bolt 10. Then, the driving mechanism is used to drive the two clamping plates 7 to move above the wood. The hydraulic cylinder 21 is started to contract, so as to drive the claw body 4 to rotate around the rotating shaft 3, so that the claw body 4 and the clamping plate 7 expand outwards. Then, the driving mechanism is used to drive the claw body 4 and the clamping plate 7 to move downwards, so that the wood is placed inside the two claw bodies 4 on both sides. At this time, the top of the wood contacts the reinforcing plate 13, and the wood squeezes the reinforcing plate 13 to move upwards, and the spring 12 contracts to generate a squeezing force. Finally, the hydraulic cylinder 21 is started to extend, so that the two claw bodies 4 on both sides are closed to each other, and the clamping plate 7 is used to grasp the wood. During grasping, the reinforcing plate 13 continuously squeezes the wood to ensure the stability of the wood during grasping, and that's it.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
