[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0023] Combined with Figures 1 - 5 , an oil - pressure - type log clamp for forklifts, which is convenient to use, of the present utility model includes forklift forks 1. At the top of the forklift forks 1, a mounting frame 2 is fixed to connect the two forklift forks 1 together. On the top of the mounting frame 2, two groups of mounting blocks 202 are symmetrically fixed. A rotating plate 601 is rotatably connected to the mounting blocks 202. Inside the rotating plate 601, a working clamping arm 6 is fixedly connected. At one end of the forklift forks 1, a fixing component 7 is fixed. The fixing component 7 includes a fixed baffle 701, which is rotatably connected inside a fixed groove 101 opened at one end of the forklift forks 1. A fixed clamping block 702 is installed in a hole on one side of the fixed baffle 701. A spring 703 is fixed to the top of the fixed clamping block 702. A pulling rope 704 is fixed to the top of the fixed clamping block 702 and passes through one side of the fixed baffle 701. The other end of the pulling rope 704 is fixed with a pulling ring 7041.

[0024] Specifically, when this case is in use, after placing the log at the junction of the forklift fork 1 and the mounting bracket 2, the drive turning plate 601 rotates at the connection with the mounting block 202, and the working clamping arm 6 fixed on the turning plate 601 rotates accordingly. The end of the working clamping arm 6 moves towards the forklift fork 1. When the working clamping arm 6 engages with the opening of the forklift fork 1, manually pull the pull rope 704 through the pull ring 7041 so that the fixed clamping block 702 at its bottom enters the inside of the fixed baffle 701, pull the fixed baffle 701 to rotate, and pull it from one side fixing groove 101 into the other side fixing groove 101. Then release the pull ring 7041, and the spring 703 pushes the fixed clamping block 702 out, which is clamped on one side of the forklift fork 1 to complete the fixation, fixing the working clamping arm 6 in the opening of the forklift fork 1. When disassembly is required, just pull the pull ring 7041 and rotate the fixed baffle 701 to reset. This component has good fixing effect, simple operation and convenient use, increases the stability of the components, does not affect the work of other components, and improves the use effect of the device.

[0025] Combined with Figures 1 - 4 , on one side of the top of the forklift fork 1, a mounting seat 3 is fixedly installed. In the middle position of the top of the mounting seat 3, a conveying box 4 is fixedly installed. On both sides of the top, an oil cylinder 5 is respectively rotatably connected through a fixing plate 301. The conveying box 4 is connected to the oil cylinder 5 through two oil pipes 401. The other end of the oil cylinder 5 is rotatably connected to the turning plate 601. When in use, start the conveying box 4, supply oil to the oil cylinder 5 through the oil pipe 401 connected to the lower part of the oil cylinder 5 to realize the outward movement of the piston rod, thereby realizing the work of the oil cylinder 5, controlling the turning plate 601 at the top of the oil cylinder 5 to rotate along the mounting block 202, driving the working clamping arm 6 to move, supply oil to the oil cylinder 5 through the oil pipe 401 above the oil cylinder 5, the piston rod moves inward, driving the turning plate 601 to rotate and driving the working clamping arm 6 to reset. Driving the movement of the working clamping arm 6 through oil pressure is simple and convenient to operate.

[0026] Two first support blocks 201 are staggeredly fixed and supported between the mounting bracket 2 and the mounting seat 3, and a second support block 203 is used to fixedly support between the mounting block 202 and the top of the mounting bracket 2. Staggeredly fixing two first support blocks 201 between the mounting bracket 2 and the mounting seat 3 can provide strong support for the device, significantly enhance the bearing capacity of the device, ensure the stability of the device, improve the connectivity between devices, and achieve the effect of mutual support. The second support block 203 between the mounting block 202 and the mounting bracket 2 also provides support for the mounting block 202.

[0027] There are two pipeline fixing parts 302 fixed on the top of the mounting base 3. The oil pipe 401 is sorted and fixed through the pipeline fixing parts 302. The pipeline fixing parts 302 include a lower fixing block 3021 fixed on the top of the mounting base 3. A upper fixing block 3022 is rotatably connected to the top of the lower fixing block 3021. A clamping groove 3024 is formed on the lower fixing block 3021. A convex block 3023 is fixed on the upper fixing block 3022. A protective pad 3025 is fixed on the arc-shaped areas of the lower fixing block 3021 and the upper fixing block 3022. When in use, after connecting the oil pipes 401 to the conveying box 4 and the oil cylinder 5 respectively, place the pipeline on the arc-shaped area on the top of the lower fixing block 3021 and rotate the upper fixing block 3022, so that the convex block 3023 on the upper fixing block 3022 is engaged into the clamping groove 3024 on the lower fixing block 3021, and fix the oil pipe 401 between the lower fixing block 3021 and the upper fixing block 3022. The setting of the pipeline fixing parts 302 effectively fixes the oil supply pipeline in a specific position, avoids the shaking and movement of the pipeline during operation, thus enhancing the stability of the pipeline, and also greatly reducing the risk of pipeline damage. It plays a role in sorting and fixing the pipeline. The protective pad 3025 fixed on the fixing surfaces of the lower fixing block 3021 and the upper fixing block 3022 also plays a role in protecting the pipeline here.

[0028] Combined Figures 1 - 3 , the working clamping arm 6, the rotating plate 601 and the mounting block 202 are rotatably connected together through bolts 602 and nuts 603, and gaskets 604 are arranged on both sides of the connection of the bolts 602. Using the cooperation of the bolts 602 and the nuts 603, the working clamping arm 6, the rotating plate 601 and the mounting block 202 are well connected together, and it does not affect the rotation of the rotating plate 601. And the gaskets 604 are arranged at the connection, which can effectively provide buffering and extend the service life of the components.

[0029] An auxiliary clamping arm 606 is fixed between the two working clamping arms 6. Rubber pads 605 are fixed on the clamping sides of the working clamping arm 6 and the auxiliary clamping arm 606. Fixing the auxiliary clamping arm 606 between the two working clamping arms 6 provides an additional support point for clamping, making the round log more stable during the clamping process, reducing the shaking and displacement of the round log, providing a safer working environment, reducing the working risk, and the rubber pads 605 fixed on the clamping sides of the working clamping arm 6 and the auxiliary clamping arm 606 can effectively increase the friction force and prevent the round log from sliding during the clamping process.

[0030] All components of the forklift fork 1, the oil cylinder 5, the working clamping arm 6 and the fixing component 7 are made of alloy steel. The alloy steel has relatively high hardness and strength, can withstand greater pressure, is suitable for dealing with work with high hardness and strength, and at the same time has certain wear resistance and corrosion resistance, and is suitable for all components of the hydraulic round log clamp.

[0031] On one side of the mounting base 3, a nameplate 303 and a reflective warning label 304 are symmetrically fixed. Fixing the nameplate 303 and the reflective warning label 304 on one side of the mounting base 3 facilitates the quick identification of the basic information of the device, and enables the device to be clearly identified even at night or in a dimly lit environment, enhancing the visibility of the device and improving production safety.
