Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, in particular to a hydraulic transport vehicle with high stability. Background Art

[0002] A pallet truck is a logistics handling equipment used to transport goods. When used at a handling station, a manual pallet truck inserts the forks it carries into the pallet holes, and manually drives the hydraulic system to lift and lower the pallet goods, and the handling operation is completed by manual pulling. It is the simplest, most effective and most common loading, unloading and handling tool among the pallet transportation tools at the handling station.

[0003] There are two ways to transport goods with a hydraulic truck: pallet loading and direct handling. When transporting goods with a pallet, in order to ensure the stability of the goods on the pallet, the hydraulic truck generally will not lift the pallet too high to avoid the goods from tipping over. Therefore, when the truck encounters obstacles such as speed bumps, the pallet will contact the obstacle, causing the pallet to detach from the fork. When transporting directly, there are no corresponding bindings. When the truck encounters an obstacle, the truck will shake, causing the goods on the fork to be unstable and tip over and scatter.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a highly stable hydraulic transport truck, which transmits power to the transmission member through the movable plate and the pad, and to the transmission member and the blocking assembly, respectively. During pallet loading, the blocking member moves out of the storage slot and rotates through the driving source, thereby resisting one end of the pallet, and then fixing the pallet between the movable plate and the blocking member for stabilization. At the same time, the binding member is unlocked, and the goods are bundled and secured. When loading directly, the goods drive the pad to move, causing the blocking member to rotate and unlock the binding member, thereby bundling the goods securely through the binding member. This solves the problem that the goods on the pallet are prone to tipping over when bumped and the pallet is prone to detaching from the fork when the hydraulic transport truck is transporting the pallet, and that the goods on the fork are prone to tipping over when bumped when loading directly.

[0019] Compared with the prior art, the present invention provides a highly stable hydraulic transport vehicle with the following beneficial effects:

[0020] 1. The present invention transmits power to the transmission member respectively through the movable plate and the pad, and the transmission member and the blocking assembly, so that during the pallet loading process, the blocking member moves out of the storage slot and rotates through the driving source, thereby resisting one end of the pallet, and then fixing the pallet between the movable plate and the blocking member to stabilize it.

[0021] 2. The present invention utilizes the socket connection between the rectangular plate and the rectangular hole so that when the storage box moves toward one side of the bracket and is connected to the side of the bracket, the connecting rod contacts the roller shaft and drives the binding piece to move away from the connecting rod, and causes the second spring to be squeezed. At this time, the rectangular plate disengages from the rectangular hole, so that the strap can be pulled out through the card plate. When the work is completed, the strap is stored in the storage box, and the blocking piece is reset and moves to the inner cavity of the storage groove. At this time, the connecting rod no longer contacts the roller shaft, and causes the second spring to restore its elasticity and move the binding piece toward the bracket, thereby causing the rectangular plate to move toward the inner cavity of the rectangular groove, thereby fixing the strap, so that the card plate no longer moves and cannot drive the strap to move, thereby achieving the goal of unlocking the binding piece for use when the device is working, and storing the binding piece in the storage box when the device is finished working.

[0022] 3. The present invention adopts a rotatable setting of the pad, so that when the forks are directly loading, if the goods carried by the forks are too small, the two pads can be rotated in opposite directions to fill the gap between the two forks, thereby preventing the goods from falling from the gap between the two forks. If the goods being carried are too long, the two pads can be rotated in opposite directions to increase the lateral distance of the device, thereby increasing the stability of the device.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0034] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a high-stability hydraulic transport vehicle.

[0035] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 5 A high-stability hydraulic transport truck includes a handle 1, a cylinder 2, two forks 3, a primary drive assembly 4 is provided between the two forks 3, a secondary drive assembly 5 is provided on the top of the forks 3, and a blocking assembly 6 is provided at the tail of the forks 3;

[0036] A transmission member 7 is provided in the middle of the inner cavity of the fork 3, and the primary drive assembly 4 and the secondary drive assembly 5 are driven by the transmission member 7 and the blocking assembly 6;

[0037] The blocking assembly 6 includes a blocking member 61 and a driving source 62. A receiving groove 8 is provided at the bottom end of the fork 3. The blocking member 61 is slidably disposed in the inner cavity of the receiving groove 8.

[0038] The primary drive assembly 4 includes a movable plate 41, which is slidably arranged between the two forks 3. When the movable plate 41 moves toward the front end of the forks 3, the movable plate 41 drives the transmission member 7 to operate, and the transmission member 7 drives the blocking member 61 to move toward the rear end of the forks 3 and move out of the storage slot 8, so that the blocking member 61 contacts the drive source 62 and rotates from a horizontal state to a vertical state. At this time, the upper end of the storage box 611 is higher than the top surface of the forks 3;

[0039] The secondary drive assembly 5 includes a pad 51, which is slidably arranged on the top of the fork 3. During the movement of the pad 51 toward the front end of the fork 3, the pad 51 drives the transmission member 7 to operate. At this time, the upper end position of the storage box 611 is higher than the top surface of the fork 3.

[0040] When the pallet is lifted up, the two forks 3 of the hydraulic transport truck enter the two fork entrances on one side of the pallet. When the pallet forks 3 enter the fork entrances, the crossbeam between the two fork entrances contacts the movable plate 41 and drives the movable plate 41 to move toward the direction of the handle 1. During the movement of the movable plate 41, the power transmission between the primary drive assembly 4 and the transmission member 7 drives the transmission member 7 to operate, and then the power transmission between the transmission member 7 and the blocking assembly 6 drives the blocking member 61 to move toward the tail end of the fork 3 and drives the blocking member 61 to separate from the storage slot 8. When the blocking member 61 separates from the storage slot 8 and contacts the driving source 62, the movable plate 41 and the pallet on the fork 3 stop moving. At this time, the blocking member 61 is driven by the driving source 62 to rotate from the horizontal state to the vertical state, so that the upper end position of the storage box 611 in the vertical state is higher than the position of the top surface of the fork 3, and the binding member 63 is unlocked, and the goods on the pallet are bound and fixed by the binding member 63.

[0041] When the hydraulic transport truck transports goods without a pallet, the goods are transported to the pad 51 on the fork 3, and the pad 51 and the goods on the pad 51 are moved synchronously toward the handle 1 through the slidability of the pad 51. During the movement of the pad 51, the pad 51 drives the transmission member 7 to operate through the power transmission between the secondary drive assembly 5 and the transmission member 7, and then the power transmission between the transmission member 7 and the blocking assembly 6 makes the blocking member 61 contact with the driving source 62, and the driving source 62 drives the blocking member 61 to rotate from a horizontal state to a vertical state, so that the upper end position of the storage box 611 in the vertical state is higher than the position of the top surface of the fork 3, and the binding member 63 is unlocked, and the goods on the pallet are bound and fixed by the binding member 63;

[0042] When the hydraulic transport truck carries cargo with a pallet, the fork 3 enters the fork entrance of the pallet. At this time, the movable plate 41 operates and drives the transmission member 7 to operate. Since the transmission member 7 and the secondary drive assembly 5 transmit power, the pad 51 is affected by the operation of the transmission member 7, which causes the pad 51 and the movable plate 41 to operate synchronously. Since the top of the fork entrance cavity does not contact the pad 51 at the top of the fork 3, when the fork 3 completely enters the fork entrance cavity, the operation of the pad 51 will not affect the movement of the fork 3. Similarly, the movement of the cargo on the pad 51 will not be affected by the movement of the movable plate 41.

[0043] Through the power transmission of the first-level drive component 4 and the second-level drive component 5 to the transmission member 7 respectively, and the power transmission of the transmission member 7 to the blocking component 6, during the pallet loading process, the blocking member 61 moves out of the storage slot 8 and rotates through the driving source 62, thereby resisting one end of the pallet, and then fixing the pallet between the movable plate 41 and the blocking member 61 for stabilization, and at the same time the binding member 63 is unlocked, and the goods are bundled and secured. When loading directly, the goods drive the pad 51 to move, so that the blocking member 61 rotates and unlocks the binding member 63, thereby bundling and securing the goods through the binding member 63, which solves the problem that the goods on the pallet are easy to tip over when bumping and the pallet is easy to detach from the fork 3 when the hydraulic transport truck is transporting the pallet, and at the same time, the goods on the fork 3 are easy to tip over when bumping when loading directly.

[0044] Further, see Figure 3 、 Figure 4 and Figure 7 , for the above-mentioned transmission member 7, the transmission member 7 includes a left driving plate 71 and a right driving plate 72. A left slide groove 73 and a right slide groove 74 are provided on both sides of the inner cavity of the fork 3. The left driving plate 71 is slidably arranged in the inner cavity of the left slide groove 73, and the right driving plate 72 is slidably arranged in the inner cavity of the right slide groove 74. Guide grooves 75 are provided on the opposite sides of the two forks 3. Connecting blocks 76 are fixedly provided at both ends of the movable plate 41. The connecting block 76 is slidably arranged in the inner cavity of the guide groove 75. The movable plate 41 is fixedly connected to the left driving plate 71 through the connecting plate. A guide groove 77 is provided on the top of the fork 3. One end of the bottom of the pad 51 is rotatably connected to a fixed block 78 through a bearing. The fixed block 78 is slidably arranged in the inner cavity of the guide groove 77 and the bottom is fixedly connected to the right driving plate 72;

[0045] The transmission member 7 also includes a main drive plate 79, a sliding groove 710 is provided in the middle of the inner cavity of the fork 3, the main drive plate 79 is slidably arranged in the inner cavity of the sliding groove 710, and main tooth grooves 711 are provided on both sides of the main drive plate 79. Built-in grooves communicating with the left slide groove 73 and the right slide groove 74 are provided on both sides of the sliding groove 710. A left gear 712 and a right gear 713 meshing with the main tooth groove 711 are respectively provided on both sides of the main drive plate 79. A left tooth groove 714 is provided on one side of the left drive plate 71, and a right tooth groove 715 is provided on one side of the right drive plate 72. The left drive plate 71 is meshed and connected with the left gear 712 through the left tooth groove 714, and the right drive plate 72 is meshed and connected with the right gear 713 through the right gear 713. The end of the main drive plate 79 near the tail end of the fork 3 is movably connected with the blocking member 61;

[0046] After the gear 713 is engaged with the main gear 711, the gear 713 is engaged with the main gear 711 and the gear 712, and the gear 713 is engaged with the main gear 711, thereby driving the main drive plate 79 to move toward the tail end of the fork 3, thereby pushing the blocking member 61 out of the storage slot 8. During the movement of the main drive plate 79 toward the tail end of the fork 3, the right gear 713 is driven to rotate counterclockwise through the meshing connection between the main gear 711 and the right gear 713. The meshing connection between the right gear 713 and the right gear 715 makes the right gear 713 rotate and drive the right drive plate 72 to move away from the tail end of the fork 3 when it rotates. Similarly, when the pad 51 moves away from the tail end of the fork 3, the movable plate 41 will also move away from the tail end of the fork 3.

[0047] Further, see Figure 4 , for the above-mentioned transmission member 7, the transmission member 7 also includes a first spring 716, a guide rod is installed in the inner cavity of the left slide groove 73, the left drive plate 71 is sleeved on the outer periphery of the guide rod, and the first spring 716 is arranged on the side of the left drive plate 71 away from the tail end of the fork 3, and the first spring 716 is sleeved on the outer periphery of the guide rod;

[0048] After the load is unloaded, the driving member 71 is reset by the driving source 62, and the movable plate 41 side is unobstructed, so that the left driving plate 71 side has no force to block. At this time, the first spring 716 recovers its elasticity and drives the left driving plate 71 to move toward the tail end of the cargo fork 3, and the left gear 712 is driven to rotate counterclockwise by the meshing connection between the left driving plate 71 and the left gear 712. The meshing connection between the left gear 712 and the main driving plate 79 drives the main driving plate 79 to move away from the tail end of the cargo fork 3, thereby storing the blocking member 61. At the same time, when the main driving plate 79 moves away from the tail end of the cargo fork 3, the meshing connection between the main driving plate 79 and the right gear 713 drives the right gear 713 to rotate clockwise, and the meshing connection between the right gear 713 and the right driving plate 72 drives the right driving plate 72 to move toward the tail end of the cargo fork 3.

[0049] Similarly, when the cargo on the pad 51 is unloaded, the driving member is reset by the driving source 62, and the pad 51 is not under pressure, so that the first spring 716 recovers its elasticity, thereby driving the movable plate 41 to move toward the tail end of the fork 3 and accommodate the blocking member 61.

[0050] Further, see Figure 5 、 Figure 8 and Figure 9 As for the above-mentioned blocking member 61, the blocking member 61 includes a storage box 611, one end of which is rotatably connected to one end of the main driving plate 79 via a bearing. The binding member 63 includes a rolled strap 631. A movable plate 612 is installed in the inner cavity of the storage box 611. One side of the movable plate 612 is rotatably connected to a roller 632 via a bearing. One end of the strap 631 is fixed to the roller 632, and the other end of the strap 631 passes through the outside of the storage box 611 and is fixedly installed with a clamping plate 633.

[0051] One side of the clamping plate 633 is attached to the surface of the storage box 611. When the goods on the fork 3 need to be tied and fixed, the clamping plate 633 moves outward, causing the strap 631 to move outward and the roller 632 to rotate.

[0052] Further, see Figure 5 、 Figure 8 and Figure 9 For the above-mentioned storage box 611, support rods 613 are fixedly installed at the four corners of the inner wall of the storage box 611. One end of the support rod 613 passes through the movable plate 612 and is fixedly installed with a stopper. A plurality of second springs 614 are provided on the side of the movable plate 612 away from the strap 631. The second springs 614 are sleeved on the outer circumference of the support rod 613.

[0053] A baffle 615 is installed at one end of the strap 631 away from the movable plate 612, one end of the roller shaft 632 passes through the baffle 615 and is rotatably connected to the baffle 615 through a bearing, a clamping hole 616 is opened at one end of the roller shaft 632, and a bracket 617 is fixedly installed at the tail end of the fork 3. The driving source 62 includes a rotating disc 621, which is installed on the outside of the bracket 617. A connecting rod 622 is fixedly installed at the axis center of one side of the rotating disc 621. The connecting rod 622 passes through the bracket 617 and is rotatably connected to the bracket 617 through a bearing. One end of the connecting rod 622 extends to the inside of the bracket 617, and a clamping block 618 is fixedly connected to the end of the connecting rod 622 close to the inside of the bracket 617. The connecting rod 622 passes through the storage box 611, and the clamping block 618 at one end is consistent with the clamping hole 616;

[0054] When the blocking member 61 moves toward the tail end of the fork 3 under the drive of the main driving plate 79 and moves out of the storage slot 8, the storage box 611 moves toward the bracket 617, so that one end of the connecting rod 622 on one side of the rotating disk 621 contacts one end of the roller 632, and the block 618 at one end of the connecting rod 622 coincides with the card space, so that the driving disk rotates to drive the connecting rod 622 to rotate, and drives the roller 632 to rotate. When the driving disk drives the roller 632 to rotate clockwise and the card plate 633 abuts against the outside of the storage box 611, the roller 632 rotates and drives the entire blocking member 61 to rotate, so that the blocking member 61 rotates from a horizontal state to a vertical state. When the strap 631 is in the working state, the roller 632 rotates clockwise to store the strap 631 outside the storage box 611 on the outside of the roller 632. When the strap 631 is pulled out, the roller 632 and the rotating disk 621 at one end rotate counterclockwise. During the process of the storage box 611 moving toward the side of the bracket 617 and contacting the side of the bracket 617, the connecting rod 622 contacts the roller 632 and drives the roller 632 to move away from the connecting rod 622, thereby causing the baffle 615, the movable plate 612 and the strap 631 to move away from the connecting rod 622 and causing the second spring 614 to be squeezed.

[0055] Further, see Figure 5 、 Figure 8 and Figure 9 As for the above-mentioned card plate 633, a rectangular hole 619 is opened on the top of the storage box 611, and a rectangular plate 634 is fixedly installed near the card plate 633 on the strap 631. The rectangular plate 634 is sleeved in the inner cavity of the rectangular hole 619. When the rectangular plate 634 is located in the inner cavity of the rectangular hole 619, the card plate 633 cannot drive the strap 631 to move outward. When the rectangular plate 634 moves out of the rectangular hole 619, the card plate 633 drives the strap 631 to move outward.

[0056] When the storage box 611 moves toward the side of the bracket 617 and contacts the side of the bracket 617, the connecting rod 622 contacts the roller 632 and drives the roller 632 to move away from the connecting rod 622, so that the baffle 615, the movable plate 612 and the strap 631 all move away from the connecting rod 622, and the second spring 614 is squeezed. At this time, the rectangular plate 634 is separated from the rectangular hole 619, so that the strap 631 can be pulled out through the clamping plate 633. When the work is completed, The strap 631 is stored in the storage box 611. At this time, the blocking member 61 is reset and moves toward the inner cavity of the storage groove 8. At this time, the connecting rod 622 no longer resists the roller shaft 632, and the second spring 614 restores its elasticity, and moves the movable plate 612, the strap 631, the roller shaft 632 and the baffle 615 toward the direction close to the bracket 617, so that the rectangular plate 634 moves toward the inner cavity of the rectangular groove, thereby fixing the strap 631, so that the clamping plate 633 no longer moves and cannot drive the strap 631 to move.

[0057] Working principle: When the hydraulic transport truck is transporting goods with a pallet, the two forks 3 of the hydraulic transport truck enter the two fork entrances on one side of the pallet. During the process of the forks 3 entering the fork entrances, the crossbeam between the two fork entrances contacts the movable plate 41 and drives the movable plate 41 to move toward the handle 1. During the movement of the movable plate 41, the movable plate 41 drives the left drive plate 71 to move synchronously. The left gear 712 is driven to rotate clockwise through the meshing connection between the left tooth groove 714 on the left drive plate 71 and the left gear 712. The left gear 712 is engaged with the main tooth groove 711 to drive the main drive plate 79 to move toward the tail end of the forks 3, thereby blocking the block 6. 1 is pushed out of the storage slot 8 and contacts the driving source 62. At this time, the driving source 62 drives the blocking member 61 to rotate from a horizontal state to a vertical state, so that the upper end of the storage box 611 in the vertical state is higher than the position of the top surface of the fork 3, and the binding member 63 is unlocked. The blocking member 61 moves out of the storage slot 8 and rotates through the driving source 62, thereby blocking one end of the pallet, and then fixing the pallet between the movable plate 41 and the blocking member 61 to stabilize it. At the same time, the binding member 63 is unlocked and the goods are tied and stabilized. When loading directly, the goods drive the pad 51 to move, causing the blocking member 61 to rotate and unlock the binding member 63, so that the goods are tied and stabilized by the binding member 63;

[0058] When the blocking member 61 moves toward the tail end of the fork 3 under the drive of the main driving plate 79 and moves out of the storage slot 8, the storage box 611 moves toward the bracket 617, so that one end of the connecting rod 622 on one side of the rotating disk 621 contacts one end of the roller 632, and the block 618 at one end of the connecting rod 622 coincides with the card space, so that the driving disk rotates to drive the connecting rod 622 to rotate, and drives the roller 632 to rotate. When the driving disk drives the roller 632 to rotate clockwise, and When the card plate 633 is against the outside of the storage box 611, the roller 632 rotates to drive the entire barrier 61 to rotate, so that the barrier 61 is rotated from a horizontal state to a vertical state. When the strap 631 is in the working state, the roller 632 rotates clockwise to store the strap 631 outside the storage box 611 on the outside of the roller 632. When the strap 631 is pulled outward, the roller 632 and the rotating disk 621 at one end rotate counterclockwise. When the storage box 611 moves toward the side of the bracket 617, the roller 632 rotates counterclockwise. During the process of moving and contacting one side of the bracket 617, the connecting rod 622 contacts the roller 632 and drives the roller 632 to move away from the connecting rod 622, so that the baffle 615, the movable plate 612 and the strap 631 are all moved away from the connecting rod 622, and the second spring 614 is squeezed. At this time, the rectangular plate 634 is separated from the rectangular hole 619, so that the strap 631 can be pulled out through the card plate 633. When the work is completed, the strap 631 is stored in In the storage box 611, the blocking member 61 is reset and moves toward the inner cavity of the storage slot 8. At this time, the connecting rod 622 no longer interferes with the roller shaft 632, and the second spring 614 recovers its elasticity, and moves the movable plate 612, the strap 631, the roller shaft 632, and the blocking plate 615 toward the bracket 617, thereby moving the rectangular plate 634 toward the inner cavity of the rectangular slot, thereby fixing the strap 631, so that the clamping plate 633 no longer moves and cannot drive the strap 631 to move;

[0059] After the cargo on the fork 3 is unloaded, the driving member is reset by the driving source 62. There is no obstruction on the side of the movable plate 41, so that there is no force blocking the side of the left driving plate 71. At this time, the first spring 716 recovers its elasticity and drives the left driving plate 71 to move toward the tail end of the fork 3. The meshing connection between the left driving plate 71 and the left gear 712 drives the left gear 712 to rotate counterclockwise. The meshing connection between the left gear 712 and the main driving plate 79 drives the main driving plate 79 to move away from the tail end of the fork 3, thereby storing the blocking member 61.

[0060] When the main driving plate 79 moves toward the tail end of the fork 3, the meshing connection between the main tooth groove 711 and the right gear 713 drives the right gear 713 to rotate counterclockwise. The meshing connection between the right gear 713 and the right tooth groove 715 makes the right gear 713 rotate and drives the right driving plate 72 to move away from the tail end of the fork 3. Similarly, when the pad 51 moves away from the tail end of the fork 3, the movable plate 41 also moves away from the tail end of the fork 3. Therefore, the pad 51 and the movable plate 41 move synchronously, and when the hydraulic transport truck carries a pallet When the fork 3 enters the fork entrance of the pallet, the movable plate 41 runs and drives the transmission member 7 to run. Since the transmission member 7 and the secondary drive assembly 5 are powered, the pad 51 is affected by the operation of the transmission member 7, which will cause the pad 51 and the movable plate 41 to run synchronously. Since the top of the fork entrance cavity will not contact the pad 51 at the top of the fork 3, when the fork 3 completely enters the fork entrance cavity, the operation of the pad 51 will not affect the movement of the fork 3. Similarly, the movement of the goods on the pad 51 will not be affected by the movement of the movable plate 41.
