Technical Field

[0001] The utility model relates to the technical field of forklift arms, in particular to a rotary distance-adjustable fork with a fork arm capable of stably supporting the fork arm. Background Art

[0002] Forklifts are industrial vehicles used for handling and stacking items and are widely used in warehousing, logistics, and production. Their primary function is to lift, move, and stack goods, especially in confined spaces or overhead locations. The forklift arm is often a key component of the forklift, used to lift and move goods. Made of steel, it is designed to be strong and durable.

[0003] However, existing forklift arms have the following disadvantages. Since the distance between the forks of most forklifts is usually fixed, but the sizes of cargo vary, the forks with a fixed distance are not convenient for carrying cargo of different sizes, resulting in unstable placement of the cargo, reducing the support stability of the forklift fork arms for the cargo, and the orientation of the forks is not convenient for rotation and adjustment as needed. Therefore, we propose a rotating fork with adjustable distance that can provide stable support. Utility Model Content

[0004] The purpose of the utility model is to provide a rotating distance-adjustable fork with a fork arm that can stably support the fork, so as to solve the problem raised in the above-mentioned background art that the distance between the fork arms of forklifts currently on the market is usually fixed, but the cargo sizes are different, the fork arms with a fixed distance are not convenient for carrying cargo of different sizes, and the orientation of the fork is not convenient for rotation and adjustment according to needs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rotary distance-adjustable fork with a fork arm that can stably support the fork, comprising a fork and a base plate, a sliding rod being slidably sleeved on one side of the fork, a panel being connected to the side of the sliding rod away from the fork, an oil cylinder and a positioning mechanism being installed in the middle of the side of the panel close to the fork, and an output end of the oil cylinder being connected to the fork, the base plate being arranged on the side of the panel away from the oil cylinder, one side of the positioning mechanism being located in the built-in groove of the fork, a positioning groove being provided on the inner side of the positioning mechanism, and the positioning mechanism comprising a fixing plate, a positioning block and a reset spring.

[0006] Preferably, a fixing plate is connected to a side of the panel close to the fork, and a return spring is provided in a built-in groove on a side of the fork close to the fixing plate.

[0007] Preferably, a positioning block is provided on one side of the return spring, and the positioning grooves are evenly spaced and distributed on one side of the fixing plate close to the positioning block.

[0011] Preferably, a valve body is installed on the middle portion of the panel near the slide rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. A positioning mechanism, a slide bar, an oil cylinder and a gear ring are provided. The oil cylinder is started to push the forks to both sides, so that the upper and lower ends of the forks slide to one side on the outside of the slide bar. At the same time, the positioning block is squeezed by the positioning groove and disengages from the positioning groove, and the positioning block squeezes the reset spring to shrink. Then, when the oil cylinder pushes the forks to the appropriate position, the reset spring rebounds and drives the positioning block to fit into the positioning groove, which can assist in limiting the forks, facilitates the fast and stable adjustment of the spacing between the forks, and meets the use of goods of different sizes. The motor drives the gear to rotate, and the gear and the gear ring are meshed and connected. The gear drives the gear ring to rotate, and the gear ring drives the panel to rotate, so that the goods can be rotated 360 degrees, which is convenient for unloading and improves the support stability and convenience of the rotary distance adjustable fork.

[0014] 2. Equipped with anti-slip strips and guard bars. The triangular anti-slip strips increase the friction between the forks and the goods to prevent left and right sliding. At the same time, the guard bar can move with the change of the fork spacing. The guard bar is always supported under the goods to prevent leakage from the damaged area under the goods, thereby improving the safety of the rotary adjustable fork.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-6 The utility model provides a technical solution: a rotary distance-adjustable fork with a fork arm that can stably support the fork arm, comprising a cargo fork 1 and a base plate 7, a sliding rod 2 being slidably sleeved on one side of the cargo fork 1, a panel 4 being connected to the side of the sliding rod 2 away from the cargo fork 1, a rotary support frame 5 being provided on the side of the panel 4 close to the base plate 7, a gear ring 13 being movably installed on the inner side of the rotary support frame 5, a motor 9 being installed in the reserved groove of the base plate 7, a gear 14 being connected to the side of the motor 9 close to the rotary support frame 5 through a coupling, a valve body 6 being installed on the middle part of the panel 4 near the slide rod 2, the gear ring 13 and the panel 4 being connected by bolts, and the base plate 7 and the rotary support frame 5 being connected by bolts.

[0024] During specific implementation, when the orientation of the fork 1 is adjusted as needed, the motor 9 drives the gear 14 to rotate, and the gear 14 is meshed with the gear ring 13, driving the gear ring 13 to rotate, and the gear ring 13 then drives the panel 4 to rotate, so that the goods can be rotated 360 degrees, which facilitates unloading and improves the convenience of the rotary adjustable distance fork.

[0025] See also Figures 1-6 , the panel 4 is installed with a cylinder 3 and a positioning mechanism 8 in the middle of the side close to the fork 1, and the output end of the cylinder 3 is connected to the fork 1, the substrate 7 is arranged on the side of the panel 4 away from the cylinder 3, one side of the positioning mechanism 8 is located in the built-in groove of the fork 1, and a positioning groove 12 is provided on the inner side of the positioning mechanism 8, the positioning mechanism 8 includes a fixed plate 801, a positioning block 802 and a return spring 803, the panel 4 is connected to the side close to the fork 1 with a fixed plate 801, the fork 1 is provided with a return spring 803 in the built-in groove on the side close to the fixed plate 801, and a positioning block 802 is provided on one side of the return spring 803, the positioning grooves 12 are evenly spaced on the side of the fixed plate 801 close to the positioning block 802, and the positioning block 802 is conical in shape.

[0026] During specific implementation, since the distance between the fork arms of most forklifts is usually fixed, but the sizes of goods are different, the fork arms with a fixed distance are not convenient for carrying goods of different sizes, which may cause the goods to be placed unstable, reducing the supporting stability of the forklift fork arms for the goods. Before supporting different goods, the distance between the forks 1 can be adjusted according to the size of the goods. By starting the oil cylinder 3 to push the fork 1 to both sides, the upper and lower ends of the fork 1 slide to one side on the outside of the slide bar 2, and at the same time, the positioning block 802 is squeezed by the positioning groove 12 and disengaged from the positioning groove 12, and the positioning block 802 squeezes the return spring 803 to contract. Then, when the oil cylinder 3 pushes the fork 1 to the appropriate position, the return spring 803 rebounds and drives the positioning block 802 to be stuck in the positioning groove 12, which can assist in limiting the fork 1, making it convenient to quickly and stably adjust the distance between the forks 1 to meet the use of goods of different sizes and improve the supporting stability of the rotary distance adjustable fork.

[0027] See also Figure 1-Figure 5 The side of the forks 1 that are close to each other is connected with equally spaced baffles 11, and the surface of the forks 1 is provided with equally spaced anti-slip strips 10, and the cross-sectional shape of the anti-slip strips 10 is triangular.

[0028] During specific implementation, since the surface of most forks 1 is relatively smooth, the goods are prone to sliding and falling. The triangular anti-slip strip 10 can be used to increase the friction between the fork 1 and the goods to prevent left and right sliding. At the same time, the barrier rod 11 can move with the change of the spacing between the forks 1. The barrier rod 11 is always supported under the goods to prevent leakage of goods from the damaged area under the goods, thereby improving the safety of the rotary adjustable distance fork.

[0029] Working principle: When using the rotary distance-adjustable fork that can be stably supported by the fork arm, first hang the base plate 7 on the forklift, connect the oil circuit of the valve body 6, and then adjust the distance between the forks 1 through the oil cylinder 3, slide rod 2 and positioning mechanism 8, and assist in limiting the fork 1. At the same time, the panel 4 can be driven to rotate 360 degrees by the motor 9, gear ring 13 and gear 14, which can meet the support and unloading needs of goods of different sizes, and the anti-slip strip 10 and the baffle bar 11 increase the friction between the goods and the fork 1, thereby improving the support stability of the rotary distance-adjustable fork. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
