Description

Technical Field

[0001] The utility model relates to the technical field of cargo forks, in particular to a cargo fork structure suitable for a field-shaped pallet. Background Art

[0002] With the rapid development of the logistics industry, cargo handling efficiency has become a key factor in improving overall logistics efficiency. Pallets, as essential tools for carrying cargo, have a direct impact on the efficiency and safety of handling operations. While there are many common types of pallets on the market, the "T-shaped" pallet is particularly popular due to its stable structure and high load-bearing capacity.

[0003] However, traditional fork mechanisms have limitations when used with cross-section pallets. A cross-section pallet typically consists of a main body and multiple crosspieces positioned underneath. These crosspieces create a gap between the pallet and the main body to facilitate fork insertion and removal. However, due to the design of traditional forks, smooth and quick access to the gap beneath the pallet is often difficult. This is especially true when working with crosspieces of varying heights and widths, which can easily cause fork jams or damage the pallet, impacting handling efficiency and increasing maintenance costs. Summary of the Invention

[0004] The present invention is made in consideration of the above-mentioned problems. The purpose of the utility model is to provide a fork structure suitable for a field-shaped pallet, which can easily pass through the gap between the cross bar and the bottom of the pallet body and is suitable for a field-shaped pallet.

[0005] To achieve the above-mentioned object, the present invention provides a fork structure suitable for a zigzag pallet, the zigzag pallet comprising a pallet body and a crossbar located below the pallet body, a gap being provided between the crossbar and the pallet body for the fork structure to pass through, the fork structure comprising a guide wheel, a load-bearing wheel, an auxiliary wheel, and a fork body, which can sequentially abut against the top of the crossbar;

[0006] The guide wheel, the load-bearing wheel and the auxiliary wheel are sequentially arranged at the bottom of the front end of the fork body along the front-back direction, and the bottom heights of the guide wheel and the auxiliary wheel are higher than the bottom height of the load-bearing wheel.

[0007] According to the fork structure suitable for the field pallet described above, there are multiple guide wheels, and the multiple guide wheels are arranged obliquely at the bottom of the front end of the fork body, and the horizontal heights of the multiple guide wheels gradually decrease from the front to the back, and the bottom surface heights of the multiple guide wheels are all higher than the bottom surface height of the load-bearing wheels.

[0008] According to the fork structure suitable for the field pallet described above, the guide wheels are provided in three numbers, and the three guide wheels are arranged obliquely in the front-to-back direction at the bottom of the front end of the fork body. The load-bearing wheel is provided in one number, and the load-bearing wheel is rotatably connected to the bottom of the fork body through a wheel frame and is located on the rear side of the guide wheel.

[0009] According to the fork structure suitable for the field pallet described above, there are two guide wheels, which are arranged obliquely at the bottom of the front end of the fork body in the front-to-back direction, and there are two load-bearing wheels, which are rotatably connected to the bottom of the fork body through a wheel frame and are arranged on the rear side of the guide wheels in the front-to-back direction.

[0010] According to the fork structure suitable for the field pallet described above, the auxiliary wheel is fixed on the wheel frame, and the top of the fork body is provided with a first hole and a second hole arranged in the front-to-back direction, the load-bearing wheel is installed directly below the first hole, and the auxiliary wheel is installed directly below the second hole.

[0011] According to the fork structure suitable for the cross-piece pallet described above, the crosspiece is provided in plurality, and the plurality of crosspieces are arranged at intervals along the front-to-rear direction of the pallet body directly below the pallet body. When the auxiliary wheel passes through the gap and disengages from the crosspiece, the fork body can abut against the top of the crosspiece.

[0012] According to the fork structure suitable for the field pallet described above, the fork body is provided with guide plates on both sides thereof, the guide plates protrude downward from the bottom of the fork body, and the guide plates can abut against the top of the crossbar.

[0013] The utility model has the following beneficial effects: during the process of inserting the fork into the cross-piece pallet, its guide wheel will contact the cross piece first. Due to its high horizontal height, it is easier to enter the gap between the cross piece and the pallet body. Since multiple guide wheels are arranged at an angle, it can raise the front end of the fork body, thereby making it easier for the load-bearing wheel to enter the gap. When the guide wheel passes over the first cross piece, its load-bearing wheel abuts against the top of the cross piece. When the load-bearing wheel moves to disengage from the cross piece, the auxiliary wheel abuts against the top of the cross piece, and the fork continues to insert forward. The auxiliary wheel disengages from the cross piece, and the guide part on the fork body abuts against the top of the cross piece, which can ensure that the fork as a whole can continue to move forward and pass through the next cross piece. It has good passability, and through the cooperation of the guide wheel, the load-bearing wheel and the auxiliary wheel, it can be made more stable and reduce shaking.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1-5 As shown, a fork structure suitable for a square pallet includes a guide wheel 2, a load-bearing wheel 3, an auxiliary wheel 4 and a fork body 5.

[0023] In this embodiment, the crossbar 1 includes a pallet body 11 and a crossbar 12 located below the pallet body 11. A gap is provided between the crossbar 12 and the pallet body 11 for the fork structure to pass through. Specifically, there are multiple crossbars 12, and the multiple crossbars 12 are arranged at intervals along the front and rear directions of the pallet body 11 directly below the pallet body 11. Its guide wheels 2, load-bearing wheels 3, auxiliary wheels 4 and fork body 5 successively abut against the top of the crossbar 12 when passing through the gap.

[0024] Specifically, the guide wheel 2, the load-bearing wheel 3 and the auxiliary wheel 4 are sequentially arranged at the bottom of the front end of the fork body 5 in the front-to-back direction, and the bottom heights of the guide wheel 2 and the auxiliary wheel 4 are higher than the bottom height of the load-bearing wheel 3. The guide wheel 2 first contacts the crosspiece 12. Due to its higher horizontal height, it is easier for it to cross the crosspiece 12 and enter the gap between the crosspiece 12 and the pallet body 11, which is conducive to crossing obstacles. As the fork continues to move forward, the guide wheel 2, the load-bearing wheel 3, the auxiliary wheel 4 and the fork body 5 sequentially contact the crosspiece 12, wherein, After the guide wheel 2 disengages from the cross piece 12, the load-bearing wheel 3 abuts against the top of the cross piece 12. When the load-bearing wheel 3 passes over the cross piece 12, the auxiliary wheel 4 abuts against the top of the cross piece 12. When the auxiliary wheel 4 passes through the gap and disengages from the cross piece 12, the fork body 5 can abut against the top of the cross piece 12, which is conducive to maintaining the height of the fork body 5, so that the guide wheel 2 can easily enter the gap between the next cross piece 12 and the pallet body 11. The fork has a small lifting range and good stability during the insertion process, and can be applied to field pallets 1 of different sizes.

[0025] When the fork body 5 contacts the top of the crossbar 12, the weight of the fork plus the field pallet 1 is greater than the weight of the fork. Therefore, the friction between the field pallet 1 and the ground will be greater than the friction between the fork and the field pallet 1, which can ensure that the fork body 5 moves forward without moving the field pallet 1.

[0026] Specifically, there are multiple guide wheels 2, and the multiple guide wheels 2 are arranged obliquely at the bottom of the front end of the fork body 5, and the horizontal height of the multiple guide wheels 2 gradually decreases from front to back, and the bottom surface height of the multiple guide wheels 2 is higher than the bottom surface height of the load-bearing wheel 3. When the multiple guide wheels 2 enter the gap between the cross piece 12 and the pallet body 11 in turn, they will gradually lift the front end of the fork body 5, causing the horizontal height of the load-bearing wheel 3 and the auxiliary wheel 4 to also increase, making it easier for the load-bearing wheel 3 to enter the gap, thereby avoiding the load-bearing wheel 3 from getting stuck.

[0027] In this embodiment, in order to match small-hole forks and large-hole forks, when using small-hole forks, the guide wheels 2 are set to three, and the three guide wheels 2 are arranged at the bottom of the front end of the fork body 5 in an inclined manner along the front-to-back direction. The load-bearing wheel 3 is set to one, and the load-bearing wheel 3 is rotatably connected to the bottom of the fork body 5 through the wheel frame, and is located on the rear side of the guide wheel 2, and one load-bearing wheel 3 is just located at its small hole. When using large-hole forks, the guide wheels 2 are set to two, and the two guide wheels 2 are arranged at the bottom of the front end of the fork body 5 in an inclined manner along the front-to-back direction. The load-bearing wheels 3 are set to two, and the two load-bearing wheels 3 are rotatably connected to the bottom of the fork body 5 through the wheel frame, and are arranged at the rear side of the guide wheel 2 in the front-to-back direction, and the two load-bearing wheels 3 are located at their large holes. The lengths of the two types of forks are similar.

[0028] Specifically, the auxiliary wheel 4 is fixed to the wheel frame, and the top of the fork body 5 is provided with a hole and a second hole 52 arranged in the front-to-back direction. The load-bearing wheel 3 is installed directly below the first hole 51, and the auxiliary wheel 4 is installed directly below the second hole 52. The size of the first hole 51 determines the number of load-bearing wheels 3.

[0029] In order to increase the height of the fork body 5 when it abuts the crosspiece 12, the fork body 5 is provided with guide plates 53 on both sides thereof. The guide plates 53 protrude downward from the bottom of the fork body 5 and can abut against the top of the crosspiece 12. The two guide plates 53 can increase the height of the fork body 5, making it easier for the guide wheel 2 to enter the gap between the next crosspiece 12 and the pallet body 11.
