Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and more specifically, to an adjustable forklift frame for handling timber. Background Technology

[0002] Forklifts are the simplest, most efficient, and most common loading, unloading, and handling tools among pallet transport vehicles, and are widely used in logistics, warehouses, factories, hospitals, schools, shopping malls, airports, stadiums, train stations, and so on.

[0003] A search revealed that patent publication number CN217676647U discloses a forklift frame for logistics management, comprising a forklift frame body, a push rod mounted on one side of the frame body, a roller mounted inside one end of the frame body, an anti-slip plate mounted on the upper surface of the frame body, and a baffle rotatably connected to one end of the frame body. The beneficial effects are: installing two sets of baffles on one side of the frame body allows the connection angle between the baffles and the frame to be adjusted via a rotating mechanism, thus blocking one end of the frame body; and by installing the anti-slip plate on the surface of the frame body, goods on the frame surface will not slip off when the frame is moved downhill, preventing damage from falling to the ground, thus improving safety. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing forklift frames require the use of binding structures when dealing with goods that are difficult to secure. However, the binding structures are usually designed according to the frame. When the stacking height of the goods changes, it is difficult to fix the ropes in the optimal position on the forklift frame, resulting in the binding position being too high or too low. This causes the center of gravity of the goods to be mismatched with the binding point. During transportation, due to inertial forces or turning actions, the goods are prone to tipping over or sliding around the binding point, posing a handling risk.

[0005] Therefore, an adjustable forklift frame for handling timber is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable forklift frame for handling timber, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable forklift frame for handling timber, comprising a forklift head, a load-bearing frame, a rear fixed frame and a front fixed frame, forklift arms welded to both sides of the front end face of the forklift head, a forklift arm lifting frame installed at the bottom of the forklift arms, and a hydraulic adjustment seat provided on the rear end face of the forklift head.

[0008] A support rod is welded to the upper end of the hydraulic adjustment seat, the load-bearing frame is welded to both sides of the forklift head, the rear end fixing frame is welded to the inner surface of the load-bearing frame, and the front end fixing frames are respectively set on the front end faces of the two sets of forklift arms.

[0009] Preferably, the load-bearing frame is square in shape and is fixed around the outer surface of the forklift head.

[0010] Preferably, the rear end fixing frame is provided in several groups, and the several groups of rear end fixing frames are distributed at equal intervals around the inner surface of the load-bearing frame.

[0011] Preferably, a hand grip is welded to the upper end of the support rod, and adjustment push rods are provided on both sides of the hydraulic adjustment seat.

[0012] Preferably, both sides of the forklift frame are connected to the forklift frame via two sets of adjusting push rods, and the end of the forklift frame away from the adjusting push rods is movably connected to a movable wheel via a rotating shaft.

[0013] Preferably, both the rear end fixing frame and the front end fixing frame have cavities for ropes to pass through, and the front end fixing frame is semi-circular in shape.

[0014] Preferably, each pair of rear end fixing frames corresponds to each other, and the bottom of the hydraulic adjustment seat is equipped with a main steering wheel.

[0015] Preferably, there are two sets of main steering wheels, and both sets of main steering wheels are movably connected to the hydraulic adjustment seat via a rotating shaft.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with the prior art, the adjustable wood handling forklift frame can be adapted to goods with different stacking heights through the load-bearing frame and the front and rear fixed frames. By adjusting the position of the rope in the rear fixed frame, the rope can always be kept close to the outer surface of the goods, avoiding tipping of the goods due to the inertia of movement when the stacking height of the goods changes and the binding position is different.

[0018] 2. Compared with the prior art, the adjustable timber handling forklift frame provides standardized binding anchor points through several fixed rings, and can precisely control the rope binding position, providing a limited position, which can bind the goods around the whole body, thereby tightly restraining the left and right sides and the entire outer perimeter of the goods, and preventing the goods from shifting outward due to centrifugal force when the forklift turns.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] As attached Figures 1 to 4 An adjustable forklift frame for handling timber is shown, including a forklift head 1, a load-bearing frame 10, a rear fixed frame 11, and a front fixed frame 12. Forklift arms 2 are welded to both sides of the front end of the forklift head 1. The forklift head 1 is the main frame of the entire equipment, integrating key components to form a rigid overall structure. The forklift arms 2 are symmetrically welded to both sides of the front end of the forklift head 1 for inserting into the bottom pallet of timber or directly lifting timber stacks. A forklift lifting frame 3 is installed at the bottom of the forklift arms 2. A hydraulic adjustment seat 5 is provided on the rear end of the forklift head 1. The forklift lifting frame 3 is installed at the bottom of the forklift arms 2. The lifting control of the forklift arms 2 is realized through the hydraulic adjustment seat 5. The hydraulic adjustment seat 5 is located on the rear end of the forklift head 1 and the height of the forklift lifting frame 3 is adjusted by hydraulic drive.

[0027] A support rod 7 is welded to the upper end of the hydraulic adjustment seat 5. The support rod 7 is welded to the upper end of the hydraulic adjustment seat 5 to transmit hydraulic adjustment power. The load-bearing frame 10 is welded to both sides of the forklift head 1 to form a frame structure. The rear fixing frame 11 is welded to the inner surface of the load-bearing frame 10 to fix the end of the rope and adjust the binding tension. The front fixing frame 12 is respectively set on the front end face of the two sets of forklift arms 2. The front fixing frame 12 guides the direction of the rope and provides the front anchor point.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] In a preferred embodiment, the load-bearing frame 10 is rectangular in shape and is fixed to the outer surface of the forklift head 1. The rectangular load-bearing frame 10 is fixed to the outer surface of the forklift head 1 by welding to form an integral support structure. Several sets of rear-end fixing frames 11 are provided, and the sets of rear-end fixing frames 11 are evenly distributed around the inner surface of the load-bearing frame 10. The sets of rear-end fixing frames 11 can fix multiple ropes or ropes at different heights. When the goods are stacked high, the upper rear-end fixing frame 11 is used, and the rope length or fixing point position is adjusted. When the goods are stacked low, the lower rear-end fixing frame 11 is used to tie them, so that the ropes always fit the outer surface of the goods and avoid the binding loosening due to changes in height.

[0031] In a preferred embodiment, a hand grip 8 is welded to the upper end of the support rod 7. The hand grip 8 is convenient for hand gripping and applying force, and releases the pressure in the hydraulic adjustment seat 5 through the internal pull bolt, thereby lowering the height of the forklift. Adjustment push rods 9 are provided on both sides of the hydraulic adjustment seat 5. The two sides of the forklift lifting frame 3 are respectively connected to the forklift lifting frame 3 through two sets of adjustment push rods 9. Each side of the hydraulic adjustment seat 5 is connected to a set of adjustment push rods 9 to form symmetry, ensuring that the force on both sides of the forklift lifting frame 3 is even when it is raised and lowered, avoiding tilting or jamming. The end of the forklift lifting frame 3 away from the adjustment push rods 9 is movably connected to the moving wheel 4 through the rotating shaft. The moving wheel 4 is connected to the forklift lifting frame 3 through the rotating shaft to achieve the movement effect.

[0032] In a preferred embodiment, both the rear fixing frame 11 and the front fixing frame 12 have cavities for ropes to pass through. The front fixing frame 12 is semi-circular in shape. The cavities in the rear fixing frame 11 and the front fixing frame 12 provide a fixed passage for the ropes. Each pair of rear fixing frames 11 corresponds to each other, forming a pair of binding points. The ropes can be tied diagonally or in a loop to fix the center of gravity of the goods at the center of the forklift frame, balance the inertial force during transportation, and prevent the goods from tilting to one side. The bottom of the hydraulic adjustment seat 5 is equipped with main steering wheels 6. There are two sets of main steering wheels 6. Both sets of main steering wheels 6 are movably connected to the hydraulic adjustment seat 5 through a rotating shaft. The main steering wheels 6 are responsible for providing directional control. They can be turned by the operator holding the handle 8 and move together with the two sets of moving wheels 4 to bear the weight.

[0033] The working process of this utility model is as follows: First, the operator holds the hand grip 8 and pushes the forklift to turn through the main steering wheel 6, aligning the symmetrically distributed forklift arms 2 with the bottom pallet of the wood or the gap between the wood, and slowly moves forward so that the forklift arms 2 are fully inserted under the wood. Then, the operator pulls the hand grip 8 and the support rod 7 and presses them down, thereby driving the piston in the hydraulic adjustment seat 5 to rise, thereby driving the adjustment push rod 9 and the forklift lifting frame 3 to rise, thereby lifting the goods.

[0034] Subsequently, the position of the rear fixing frame 11 at the corresponding height is adjusted according to the height of the stacked wood. First, one end of the binding rope is passed through the semi-circular notch of the front fixing frame 12 and tied to form a front anchor point. The other end passes over the wood and goes around to the cavity of the rear fixing frame 11 at the corresponding height at the load-bearing frame 10. Then, the rope is tied at the selected position to fix the wood at different heights. Multiple other ropes are wrapped around the wood and finally tied in the inner cavity of the rear fixing frame 11 to achieve a circular binding. The operator holds the handle 8 and pushes the forklift. The main steering wheel 6 adjusts synchronously with the steering angle of the handle. The moving wheel 4 assists the main steering wheel 6 in guiding. After reaching the target position, the operator pulls the hydraulic release bolt in the handle 8, the hydraulic adjustment seat 5 is depressurized, and the adjustment push rod 9 retracts synchronously. The forklift lifting frame 3 slowly descends under the weight of the wood until the forklift arm 2 fully contacts the ground and the wood lands smoothly. The above is the working principle of this adjustable wood handling forklift frame.
