Description

Technical Field

[0001] The present invention relates to the field of transport vehicles, in particular to a high-lift anti-dumping and anti-dropping electric hydraulic transport vehicle. Background Art

[0002] A pallet truck is a piece of logistics handling equipment used to transport goods. When in use, an electric hydraulic pallet truck inserts its carrying fork into the pallet hole, and the hydraulic system is driven by electricity to lift and lower the pallet goods, and the handling operation is completed by human pull. It is the simplest, most effective and most common loading and unloading and handling tool among pallet transport tools. Common pallet trucks have limited lifting capabilities and cannot effectively prevent the pallet truck from tipping over. The mechanism to prevent the transported items from falling is relatively simple, and the function of preventing the falling items is relatively limited.

[0003] To this end, Chinese invention patent No. 202121583330.X discloses a scissor-type hydraulic transporter, comprising a base and handrails. The base is provided with a scissor-type lifting frame, which is provided with a fork frame. The base is also provided with a hydraulic cylinder for pushing the fork frame up and down. The lower surface of the fork frame is provided with a telescopic support member, and the telescopic support member is also provided with a first fixing member for locking the length of the telescopic support member. The telescopic support member is provided with a roller at one end away from the connection between the telescopic support member and the fork frame. The utility model supports the fork frame through the telescopic support member, so that when the transporter is transporting items, the fork frame is not easily broken or bent due to uneven force when the lift is large.

[0004] Through research on the above-mentioned scissor-type hydraulic transporter equipment, it was found that when transporting items, the fork frame is not easily broken or bent due to uneven force when the lift is large, but it cannot solve the problem of the transporter tilting or even tipping over when transporting heavy items. When transporting heavy items, it consumes manpower, and the items are easily dropped and damaged on uneven roads. When stacking items, it cannot reasonably utilize higher space.

[0005] Therefore, we are in urgent need of inventing a hydraulic transport vehicle that has a higher lift and prevents tipping, which saves time and effort and prevents falling, to solve the above problems. Summary of the Invention

[0006] In response to the above problems, the present invention provides a high-lift anti-dumping and anti-dropping electric hydraulic transport vehicle. By arranging a vehicle body moving mechanism, a transport fork mechanism, a lifting mechanism, an anti-rollover mechanism and anti-drop mechanisms on both sides, the functions of moving, transporting, lifting, anti-rollover and anti-dropping are integrated into one, which not only increases the function of the transport vehicle, but also protects the operator and improves work efficiency. When transporting large and heavy items, the transport vehicle will not dump, and when the road surface is uneven, the items will not fall from the side. It has a higher lift and rationally utilizes the space in the height direction.

[0030] The technical solution of the present invention will be further specifically described below through examples and in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0032] Examples, such as Figure 1-8 As shown, a high-lift anti-dumping and anti-dropping electric hydraulic transport vehicle includes a vehicle body moving mechanism 1, a transport fork mechanism 2, a lifting mechanism 3, an anti-rollover mechanism 4 and anti-drop mechanisms 5 on both sides;

[0033] The vehicle moving mechanism 1 contacts the ground through four wheels 103, the vehicle body 104 is provided with a wheel rod connected to the wheel 103, a motor A101 is provided at the rear lower part of the vehicle body 104, and a wheel set 102 is provided at the wheel rod at the rear lower part. Above the vehicle body 104 is a gravity block 105, and the anti-rollover mechanism 4 is inserted into the mounting groove of the gravity block 105 and fixed and in contact with the ground. The lifting mechanism 3 is installed on the vehicle moving mechanism 1 by flipping the hydraulic rod 301, the flip plate 302 and the support column 308. The transport fork mechanism 2 is fixedly connected to the lifting plate 303 of the lifting mechanism 3 through the fork mounting plate 205 to realize the fork insertion of the transported object, and the push plates 501 in the anti-drop mechanisms 5 on both sides are installed on the sides of the forks 206 in the transport fork mechanism 2;

[0034] When transporting items, people drive the vehicle moving mechanism 1 to a position close to the items, and then drive the fork 206 in the fork mechanism 2 to a suitable position according to the size of the items. Then the lifting mechanism 3 drives the fork 206 in the fork mechanism 2 to contact the ground and align with the pallet hole under the items by flipping the hydraulic rod 301 and the flip plate 302. Then the vehicle body mechanism 1 is driven forward to fork in the items, and the flip hydraulic rod 301 is driven backward again to lift the items. Then the first group of hydraulic rods 305 and the second group of hydraulic rods 306 in the lifting mechanism 3 are used to lift the items to a specified height. Then the vehicle body mechanism 1 is driven to the location where the items are to be stored. During the operation of the transport vehicle, the anti-drop mechanism 5 and the anti-rollover mechanism 4 on both sides work to prevent the items from falling and prevent the transport vehicle from overturning.

[0035] Examples, such as Figure 3-4 As shown, the transport fork mechanism 2 includes: a motor B201, a gear 202, a rack 203, a fork sliding plate 204, a fork mounting plate 205, a fork 206 and a pressure relief plate 207;

[0036] A motor B201 is provided below the transport fork mechanism 2, a gear 202 is fixed to the motor B201, a rack 203 is fixed in a groove of a fork mounting plate 205, a fork 206 is connected to a fork sliding plate 204, a pressure relief plate 207 is mounted on the fork mounting plate 205, and the transport fork mechanism 2 is fixed to a first set of hydraulic rods 305;

[0037] When the equipment moves to the designated position, according to the size of the item, the motor B201 starts to drive the gear 202 to rotate, and then drives the rack 203 to move, thereby driving the fork sliding plate 204 to slide in the groove of the fork mounting plate 205, thereby driving the fork 206 to move to the designated position. A pressure relief plate 207 is installed on the fork mounting plate 205 to prevent the fork 206 from tilting when transporting items, causing the transported items to slide toward the fork mounting plate 205 and causing damage to the transported items.

[0038] Examples, such as Figure 5-6 As shown, the lifting mechanism 3 includes: a flip hydraulic rod 301, a flip plate 302, a lifting plate 303, a support block A304, a first group of hydraulic rods 305, a second group of hydraulic rods 306, a support plate 307 and a support column 308;

[0039] One end of the flip hydraulic rod 301 is installed in the large groove at the top of the gravity block 105, and the other end is fixed to the flip plate 302. The flip plate 302 is installed at the front end of the vehicle body 104. The first set of hydraulic rods 305 is installed on the lifting plate 303, and the lifting plate 303 is installed on the second set of hydraulic rods 306. The support block A304 is installed on the back of the flip plate 302, and the support plate 307 is installed above the flip plate 302. Two support columns 308 are installed symmetrically, one end of which is installed in the small groove of the gravity block 105, and the other end is installed on the support plate 307;

[0040] When the two forks 206 are separated to the designated position according to the size of the items to be transported, the flip hydraulic rod 301 works to flip the flip plate 302 forward by a certain angle, thereby driving the lifting plate 303 to flip, thereby driving the fork mounting plate 205 to flip, and then making the end of the fork 206 contact the ground. At this time, the fork tilts forward, and the equipment moves to insert the fork 206 into the pallet of the item to be transported. The flip hydraulic rod 301 works to flip the flip plate 302 backward by a certain angle, thereby driving the lifting plate 303 to flip backward by a certain angle, and then driving the transport fork mechanism 2 to flip. After the flip plate flips backward, the support block A304 contacts the gravity block 105, and then supports the flip plate 302. At this time, the fork 206 tilts backward, and the items on the fork As the forks 206 move toward the bottom of the forks 206, the objects being carried press down the pressure relief plate 207, causing the first set of hydraulic rods 305 to lift the forks 206, thereby lifting the objects being carried to the designated location. When the height to be carried is higher, the second set of hydraulic rods 306 installed in the flip plate 302 starts to work, thereby lifting the lifting plate 303, which in turn lifts the first set of hydraulic rods 305, which in turn lifts the forks 206, thereby lifting the objects being carried to the designated location. As the lifting plate 303 rises, it also lifts the support plate 307, which contacts the fork mounting plate 205 and supports the fork mounting plate 205 through the support columns 308 at the rear end, thereby supporting the objects being carried, thereby enabling the carrying of heavier objects. As the support plate 307 rises, it drives the support columns 308 to slide in the grooves on the gravity block 105, allowing the support plate 307 to rise and remain in contact with the fork mounting plate 205.

[0041] Examples, such as Figure 7 As shown, the rollover prevention mechanism 4 includes: a rollover support rod 401 and a support ball 402;

[0042] The support ball 402 installed at the lower part of the rollover support rod 401 contacts the ground, so that the support ball 402 is supported on the ground, and the support force is transmitted to the gravity block 105 through the rollover support rod 401, thereby supporting the device;

[0043] When the device rolls over, the support ball 402 installed at the bottom of the rollover support rod 401 contacts the ground, and then the support ball 402 is supported on the ground. The supporting force is transmitted to the gravity block 105 through the rollover support rod 401, and then the device support column is turned to support the device when it rolls over, so that the rollover angle will not be too large. When the device moves, the support ball 402 rotates on the rollover support column 401 without interfering with the movement of the device.

[0044] Examples, such as Figure 8 As shown, the anti-drop mechanism 5 on both sides includes: a pushing plate 501, an anti-drop main plate 502, an anti-drop plate 503, a straight groove plate 504, a connecting plate 505, a supporting slider 506, a slide plate 507, a support rod 508, a sliding plate 509, a support block B510 and a column 511;

[0045] The pushing plates 501 at both ends of the two forks 206 are connected to the anti-drop main board 502, and a slide plate 507 is installed on the outside of the anti-drop main board 502. The support slider 506 slides on the slide plate 507, and the support rods 508 on both sides are respectively forked into the support slider 506 and fixed. The lower end of the support rod has a pulley in contact with the ground. One end of the connecting plate 505 is fixed to the support slider 506, and the other end is fixed to the straight groove plate 504. The straight groove plate 504 is connected to the anti-drop plate 503. The inner side of the anti-drop plate 503 is used to fix objects, and the outer side is used to drag the support block B510. The sliding plate 509 is clamped between the support block B510 and the anti-drop plate 503. A column 511 with a ball bearing is installed at the bottom of the anti-drop main board 502, which can support the anti-drop main board 502 and prevent the anti-drop main board 502 from affecting the movement of the equipment.

[0046] When the two forks 206 are separated, the pushing plate 501 installed on the side of the fork 206 pushes the anti-drop main board 502 to the designated position. After the fork 206 forks the object, the fork 206 rises and drives the object to rise, and then the top of the object contacts the anti-drop plate 503, and then drives the anti-drop plate 503 to rise, thereby driving the straight groove plate 504 to rise, thereby driving the connecting plate 505 to move, and then driving the supporting slider 506 to move on the slide plate 507. The higher the position of the object is raised, the more the supporting slider 506 moves toward the fork 206. The movement of the supporting slider 506 drives the straight groove plate 504 to move. After moving to the designated position, the anti-drop main board 502 is supported by the support rod 508 and the supporting slider 506, and then the anti-drop plate 503 is lifted. 03 supports, so that when the object falls to the sides, the object can be stuck and the object cannot fall to the sides. When the object rises to the specified position, the object will continue to rise and will drive the sliding plate 509 to rise. The sliding plate 509 can slide into the anti-drop main board 502 to save space. When the object rises to the specified position, the support slider 506 slides to the lower part of the support block B510. The support slider 506 contacts the lower end of the support block B510. The support slider 506 supports the support block B510, thereby supporting the sliding plate 509, and then supporting the anti-drop plate 503. A column 511 with a ball bearing is installed at the bottom of the anti-drop main board 502, which can support the anti-drop main board 502 and prevent the anti-drop main board 502 from affecting the movement of the equipment.
