Description

Technical Field

[0001] The present application relates to the field of forklifts, and in particular to a novel forklift fork structure. Background Art

[0002] The fork is the most commonly used picking device on a forklift, hence the name. A forklift is equipped with two forks shaped like the letter L. The horizontal section of the fork is the working part that places the goods, and the vertical section is the supporting part. When using existing forklift forks, they need to be used with a pallet. The goods are placed on the pallet, and there are slots on the underside of the pallet for the forks to be inserted. When a forklift is moving goods, the goods need to be kept close to the forklift to prevent the forklift from tilting due to the center of gravity of the goods being far away. When a forklift needs to move goods placed in the middle of a truck, it is difficult for the forklift to get close, and the forks can only be inserted to the edge of the pallet. The center of gravity of the goods is far away from the forklift, and the forklift needs to repeatedly pick up the goods and adjust the goods to the edge of the truck, which is very labor-intensive for the staff.

[0003] In order to facilitate the adjustment of the position of the goods on the forks, a load-bearing wheel structure can be set on the horizontal section of the forks. When the forks lift the goods, the relative position of the goods and the forklift is adjusted by the load-bearing wheel structure so that the center of gravity of the goods is close to the forklift. However, due to the existence of the load-bearing wheel structure, the pallet is easy to slide on the forks, which makes it inconvenient to fix the goods.

[0004] In order to limit the position of pallet cargo, a baffle that slides along the fork is usually set on the horizontal section of the fork. The baffle is used to limit the position of the pallet cargo and push the pallet to move at the same time. However, the baffle will form a bulge on the horizontal section of the fork, forming an obstruction, making it inconvenient for the fork to insert and withdraw the pallet.

[0005] Therefore, a new forklift fork structure is needed. Utility Model Content

[0006] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.

[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a new forklift fork structure, including: a main frame, which is installed on the forklift and is used to move up and down for lifting operations; a fork member, which is provided with two groups, and the two groups of fork members are arranged on the main frame with adjustable spacing; the fork member includes: a vertical part slidingly arranged on the main frame and a horizontal part connected to the vertical part, the horizontal part forks the pallet; a push block assembly is provided on the horizontal part for pushing the push plate to slide along the horizontal part; the push block assembly includes at least one movable block for pushing the pallet and a locking structure for locking the movable block; the push block assembly The component also includes: a first motor, fixed on the forklift, with its axis parallel to the horizontal part; a first screw rod, fixed at the power output end of the first motor, with its rotation axis arranged in the same direction as the horizontal part; a sliding block, sliding along the horizontal part, and being threadedly connected to the first screw rod, the first screw rod passes through the sliding block and is threadedly connected to the sliding block; a spring is arranged on the sliding block, with its two ends respectively connected to the sliding block and the movable block; the movable block is movably arranged on the sliding block, and the movable block has a vertical surface abutting against the side of the pallet on the side close to the main frame, which is used to push the pallet, and the movable block has an inclined surface on the side away from the main frame, and the inclined surface gradually approaches the main frame from bottom to top.

[0008] The two forks with adjustable spacing make it possible to adapt to pallets of different sizes and ensure stability when lifting larger goods. The push assembly allows the fork to push the pallet to adjust the position of the goods after picking up the goods. The movable block prevents the movable block from blocking the horizontal part when it is inserted into or pulled out of the pallet, making it easier to insert and pull out the horizontal part.

[0009] Furthermore, the locking structure includes: a locking shaft, fixedly arranged on the horizontal part, used to abut against the inclined surface of the movable block to move the movable block; a limiting protrusion, fixed on the movable block, used to abut against the sliding block for limiting; a locking groove, opened on the sliding block, for the locking shaft to be embedded.

[0010] The locking shaft and the inclined surface on the movable block that contacts the locking shaft ensure that when the horizontal portion is inserted into or removed from the tray, the locking shaft contacts the inclined surface of the movable block, causing the movable block to move out of contact with the tray, thereby preventing the movable block from causing obstruction. Furthermore, the locking slot is provided, into which the locking shaft fits, ensuring secure locking.

[0011] Furthermore, a receiving groove is provided on the sliding block, the movable block is arranged in the receiving groove, the spring is arranged in the groove, and the two ends are respectively abutted against the bottom wall of the receiving groove and the movable block.

[0012] The accommodating groove is provided so that the movable block moves in the accommodating groove, and then under the action of the spring, the movable block has two states: being able to contact with the side surface of the tray and being unable to contact with the side surface of the tray.

[0013] Furthermore, the movable block is provided with a rotating shaft portion, and the movable block is rotatably arranged in the accommodating groove via the rotating shaft portion.

[0014] The movable block is rotated in the receiving groove by rotating the shaft, so that when the inclined surface contacts the tray or the locking shaft, the movable block rotates so that the vertical surface is partially received in the receiving groove to avoid obstruction.

[0015] Furthermore, an adjustment slot extending along the horizontal portion is provided on the horizontal portion, the sliding block is slidably arranged in the adjustment slot, and the locking shaft is located on a side of the sliding block away from the main frame.

[0016] The sliding block slides along the adjusting slot, and when the vertical surface of the movable block contacts the side surface of the tray, the tray can be driven to move toward the main frame.

[0017] Furthermore, mounting holes for inserting the two ends of the locking shaft are opened on the two side walls of the adjustment groove, and multiple groups of mounting holes extend along the horizontal part. The locking shaft includes a screw part and two end parts sleeved on the screw part, and the two end parts are respectively inserted into the two mounting holes.

[0018] By adjusting the two end portions to be inserted into mounting holes at different positions, the position of the locking shaft in the adjustment slot is adjusted. When the size of the tray is large, the locking shaft is installed on the mounting hole away from the main frame.

[0019] Furthermore, the two end portions are threadedly connected to the screw portion.

[0020] By rotating the two end portions, the end portions are extended along the axis direction of the locking shaft, so as to be conveniently inserted into the mounting hole.

[0021] Furthermore, a load-bearing wheel in contact with the bottom of the tray is rotatably connected to the horizontal portion, and the load-bearing wheel has a tangent in the same direction as the horizontal portion.

[0022] The tray is supported by the provided load-bearing wheels, so that the tray can be easily moved on the horizontal portion.

[0023] Furthermore, a second motor is fixedly connected to the main frame, and a bidirectional screw is fixedly connected to the power output end of the second motor. The axial direction of the bidirectional screw is consistent with the sliding direction of the vertical part. The bidirectional screw passes through the two vertical parts and is threadedly connected to the vertical parts. The thread options of the two vertical parts are opposite.

[0024] By providing a second motor and a bidirectional screw rod, the two fork members rotated by the bidirectional screw rod can move toward or away from each other, so as to adjust the distance between the two fork members.

[0025] Furthermore, an anti-slip rubber layer is provided on the load-bearing wheel.

[0026] The anti-skid rubber layer prevents the pallet from slipping axially on the load-bearing wheels.

[0027] The beneficial effects of this application are:

[0028] 1. By setting up two forks with adjustable spacing, it is possible to adapt to pallets of different specifications while ensuring stability when forking large goods. By setting up a second motor and a bidirectional screw, the motor controls the rotation of the screw to accurately adjust the spacing between the two forks.

[0029] 2. Through the load-bearing wheels, when the forks lift the pallet cargo, it is convenient to move the pallet closer to the forklift, so that the center of gravity of the cargo is close to the forklift, avoiding the danger of the forklift tilting.

[0030] 3. Through the set movable block, when the pallet needs to be moved towards the forklift, the movable block can be used to push the pallet to move, reducing the workload. At the same time, when the forklift pulls out the pallet, the movable block can be avoided from causing obstruction, making operation easier.

[0031] 4. By setting the sliding block, the first motor and the first screw rod, the first motor outputs power to drive the first screw rod to rotate, and then the sliding block moves, so that the movable block moves synchronously, pushing the pallet toward the forklift, reducing labor intensity.

[0032] 5. By setting the locking shaft and multiple sets of mounting holes, the locking shaft position can be adjusted according to pallets of different sizes, so that the sliding block can be moved to the locking shaft position as quickly as possible, reducing the distance the sliding block needs to move, saving time and improving work efficiency.

[0033] The present application provides a novel forklift fork structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0048] Reference Figure 1-4A new forklift fork structure includes: a main frame 100, a fork member 101, a first motor 102, a first screw rod 103, a sliding block 104, a spring 105, a movable block 106, a locking shaft 107, a limiting protrusion 108, and a locking groove 109. The main frame 100 is installed on the forklift for moving up and down for lifting operations. There are two fork members 101 for forking pallets. The fork member 101 includes a vertical portion 110 slidably arranged on the main frame 100 and a horizontal portion 111 connected to the vertical portion 110. The upper end surface of the horizontal portion 111 contacts the pallet and forks the pallet. The two fork members 101 adjust the distance between the two fork frames through the movement of the vertical portion 110 on the main frame 100.

[0049] The horizontal portion 111 is provided with an adjustment slot 112 extending along the horizontal portion 111. A sliding block 104 is slidably connected within the adjustment slot 112. Furthermore, a first motor 102 is fixedly connected to the fork member 101. A first screw 103 is fixedly connected to the output end of the first motor 102. The rotation axis of the first screw 103 is aligned with the horizontal portion 111. The first screw 103 passes through the sliding block 104 and is threadedly connected thereto. When the first motor 102 outputs power, the first screw 103 rotates, thereby driving the sliding block 104 along the horizontal portion 111. Under forward and reverse power output from the first motor 102, the sliding block 104 can move in both directions.

[0050] A second motor 113 is fixedly connected to the main frame 100. A bidirectional screw 114 is fixedly connected to the power output end of the second motor 113. The axial direction of the bidirectional screw 114 is consistent with the sliding direction of the vertical portion 110. The bidirectional screw 114 passes through the two vertical portions 110 and is threadedly connected to the vertical portions 110. The thread options of the two vertical portions 110 are opposite. The second motor 113 and bidirectional screw 114 are configured to enable the two forks 101 to move toward or away from each other through the rotation of the bidirectional screw 114, thereby adjusting the spacing between the two forks 101.

[0051] The sliding block 104 is provided with a receiving groove 115, and the movable block 106 is arranged in the receiving groove 115. The movable block 106 has two states. In the first state, the movable block 106 is completely located in the receiving groove 115 and cannot push the tray; in the second state, a portion of the movable block 106 extends out of the receiving groove 115, so that the vertical surface can push the tray. In one embodiment, the movable block 106 is slidably arranged on the sliding block 104, and the spring 105 is arranged on the sliding block 104, and the two ends of the spring 105 are fixedly connected to the sliding block 104 and the movable block 106 respectively. The movable block 106 has a vertical surface on the side close to the main frame 100 that abuts against the side of the tray for pushing the tray, and the movable block 106 has an inclined surface on the side away from the main frame 100, and the inclined surface gradually approaches the main frame 100 from bottom to top. When the movable block 106 moves synchronously with the sliding block 104 and the inclined surface contacts the tray, the movable block 106 slides downward to squeeze the spring 105 and does not push the tray to move; when the movable block 106 moves synchronously with the sliding block 104 and the vertical surface contacts the tray, the movable block 106 pushes the tray to move.

[0052] In another embodiment, a receiving slot 115 is defined on the sliding block 104, and a movable block 106 is rotatably mounted within the receiving slot 115. A spring 105 is positioned within the same slot, with its ends abutting the bottom wall of the receiving slot 115 and the movable block 106, respectively. The movable block 106 has a pivoting axis, which allows it to be pivoted within the receiving slot 115. When the inclined surface contacts the tray, the movable block 106 rotates to compress the spring 105, preventing the tray from being pushed. When the vertical surface contacts the tray, the movable block 106 pushes the tray forward.

[0053] Locking shaft 107 is disposed on horizontal portion 111 and is configured to abut against the inclined surface of movable block 106, causing movable block 106 to rotate, positioning movable block 106 within receiving slot 115 without obstructing the tray. Locking slot 109 is defined on sliding block 104 and is configured to receive locking shaft 107. When sliding block 104 moves to the position of locking shaft 107, locking shaft 107 abuts against the inclined surface of movable block 106, causing movable block 106 to rotate, positioning movable block 106 within receiving slot 115 in the first position. Simultaneously, locking shaft 107 is embedded in locking slot 109.

[0054] The limiting protrusion 108 is fixed on the movable block 106 and is used to abut and limit the sliding block 104. When the movable block 106 is in the second state and the vertical surface abuts and pushes the tray, the limiting protrusion 108 abuts the sliding block 104 to limit the movable block 106.

[0055] Mounting holes 116 are provided on both side walls of the adjustment slot 112 for inserting the two ends of the locking shaft 107. Multiple groups of mounting holes 116 extend along the horizontal portion 111. The locking shaft 107 includes a screw portion 117 and two end portions 118 sleeved on the screw portion 117. The end portions 118 are threadedly connected to the screw portion 117 and are respectively inserted into the two mounting holes 116. By rotating the two end portions 118, the end portions 118 are extended along the axis of the locking shaft 107, making it easier to insert them into the mounting holes 116.

[0056] The horizontal portion 111 is rotatably connected to a load wheel 119 in contact with the bottom of the tray, and the load wheel 119 has a tangent in the same direction as the horizontal portion 111. The bottom of the tray is supported by the load wheel 119, and the rotation of the load wheel 119 facilitates the movement of the push tray.

[0057] The load-bearing wheels 119 are provided with an anti-skid rubber layer to prevent the tray from slipping axially on the load-bearing wheels 119 .

[0058] Working process or usage:

[0059] 1. The first motor 102 outputs power to move the sliding block 104 to the position of the locking shaft 107. The locking shaft 107 is embedded in the locking groove 109, so that the movable block 106 is in the first state, which facilitates the insertion of the horizontal portion 111 into the lower side of the pallet for forking.

[0060] 2. When the tray is located between the main frame 100 and the sliding block 104, the first motor 102 is started to output power, which in turn drives the first screw rod 103 to rotate, driving the sliding block 104 to move, so that the locking shaft 107 disengages from the locking groove 109. At this time, the movable block 106 is in the second state.

[0061] 3. The first motor 102 continuously outputs power to drive the sliding block 104 to move, so that the vertical surface of the movable block 106 contacts the side of the pallet, pushing the pallet toward the main frame 100, and facilitating the movement of the pallet through the load-bearing wheels 119. At the same time, the movable block 106 limits the pallet to prevent it from sliding.

[0062] 4. When the pallet cargo is forked to the destination, the first motor 102 is started to output power in the reverse direction, driving the sliding block 104 to move toward the locking shaft 107, so that the locking shaft 107 is re-embedded in the locking groove 109, and the movable block 106 returns to the first state, at which time it is convenient to withdraw the fork member 101.

[0063] 5. By rotating the end portion 118 , the locking shaft 107 can be easily installed in the installation hole 116 at different positions, so that the tray is located between the sliding block 104 and the main frame 100 .

[0064] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
