DETAILED DESCRIPTION

[0018] 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 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 creative work are within the scope of protection of the present invention. Example

[0019] See also Figure 1-9 The present invention provides a technical solution: a pallet truck mechanism capable of forking double-sided pallets without damage, comprising a truck body 1, a transport pallet 11 is placed at the front end of the truck body 1, and a socket 12 is provided inside the transport pallet 11; The fork-picking mechanism 2 includes a lifting rod 21 disposed at the front end of the transport vehicle body 1, and a transverse plate 22 is fixedly connected to one end of the lifting rod 21 away from the transport vehicle body 1, and two forks 23 are slidably connected above the transverse plate 22; An adjustment mechanism 3, the adjustment mechanism 3 is located on both sides of the fork 23, and the adjustment mechanism 3 can adjust the fork 23 so that the fork 23 is inserted into the insertion hole 12 to fork the transport pallet 11; A lifting mechanism 4, which is located inside the fork 23 and can assist in lifting the transport pallet 11 when the fork 23 is inserted into the insertion hole 12 through the adjustment mechanism 3; When the present invention is in use, the operator can adjust the fork 23 through the adjustment mechanism 3 to facilitate the fork 23 to be inserted into the socket 12 inside the transport pallet 11. After the fork 23 is inserted into the socket 12, the lifting mechanism 4 on the outside of the fork 23 extends out, and the lifting mechanism 4 pushes out the lifting plate 45, making it convenient for the lifting plate 45 to assist in lifting the forked transport pallet 11, ensuring that the fork 23 is more stable when forking the transport pallet 11.

[0020] The adjustment mechanism 3 includes hydraulic cylinders 31 respectively arranged on the outer sides of the forks 23, the hydraulic cylinders 31 are fixedly connected to the cross plate 22, the hydraulic cylinders 31 are slidably connected to one end of the forks 23 with a hydraulic rod 32, the end of the hydraulic rod 32 away from the hydraulic cylinder 31 is fixedly connected to the outer wall of the forks 23, and the two ends of the forks 23 are provided with adjustment members 5 for driving the hydraulic cylinders 31 to adjust the forks 23; When the operator adjusts the truck body 1, there is no need to adjust the truck body 1. The operator only needs to adjust the position of the fork 23 through the hydraulic cylinder 31. The hydraulic cylinder 31 drives the fork 23 to slide and connect with the cross plate 22 through the adjustment member 5, so that the fork 23 can be inserted into the socket 12 provided on the transport pallet 11, which not only saves the workload of the truck body 1, but also improves the transport efficiency.

[0021] The adjusting member 5 includes distance measuring sensors 51 respectively arranged at both ends of the fork 23, the distance measuring sensors 51 are fixedly connected to the outer wall of the fork 23, and the distance measuring sensors 51 are connected to the hydraulic cylinder 31 circuit; when the fork 23 needs to be used to fork the transport pallet 11, the distance measuring sensors 51 located at both ends of the fork 23 measure the position of the socket 12 and feed back to the hydraulic cylinder 31 at the same time, and the hydraulic cylinder 31 drives the hydraulic rod 32 to slide the fork 23 and the cross plate 22. When the fork 23 is aligned with the socket 12 opened on the transport pallet 11, the hydraulic cylinder 31 stops driving the hydraulic rod 32 to push the fork 23, so as to prevent the fork 23 from abutting and damaging the inner wall of the socket 12 and the surface of the transport pallet 11 due to the fork 23 not being aligned with the socket 12, thereby preventing the fork 23 from damaging the transport pallet 11.

[0022] The lifting mechanism 4 includes a sliding groove 41 provided on the outer side of the fork 23, and limiting grooves 42 are provided at both ends of the sliding groove 41.

At this time, the spring 1 43 is reset to lift the limit plate 44, and the lifting plate 45 located at the end of the limit plate 44 away from the spring 1 43 extends out of the fork 23. The limit plate 44 slides inside the limit groove 42 and is clamped with the end of the limit groove 42 close to the sliding groove 41. The extension of the lifting plate 45 can assist the fork 23 in forking the transport pallet 11, making it more stable for the fork 23 to fork the transport pallet 11, which is convenient for the transport vehicle body 1 to transport and stack goods.

[0023] The clamping member 6 includes a clamping groove 61 formed at one end of the limit plate 44 away from the transport vehicle body 1, a second spring 62 is fixedly connected to the inner wall of the clamping groove 61, and a clamping block 63 is fixedly connected to one end of the second spring 62 away from the bottom of the clamping groove 61, the clamping block 63 is located inside the clamping groove 61 and is slidably connected to the clamping groove 61, and a clamping hole 64 is formed at one end of the sliding groove 41 away from the transport vehicle body 1, and the clamping block 63 is located inside the clamping hole 64 and is slidably connected to the clamping hole 64; When the lifting plate 45 is located inside the sliding groove 41, the engaging block 63 located inside the limiting plate 44 is engaged with the engaging hole 64. When the engaging block 63 slides into the engaging groove 61 through the disengagement member 7, the spring 2 62 is compressed, and the limiting plate 44 is disengaged from the engaging hole 64. The spring 1 43 is reset to be able to drive the lifting plate 45 to move through the limiting plate 44. When the lifting plate 45 is retracted into the sliding groove 41, when the limiting plate 44 slides to the engaging hole 64, the engaging block 63 is reset by the spring 2 62, so that the engaging block 63 is lifted up to the engaging hole 64. At this time, the limiting plate 44 is engaged with the engaging hole 64, the spring 1 43 is compressed, and the lifting plate 45 is retracted into the sliding groove 41, so as to facilitate the auxiliary fork 23 to fork and carry the pallet 11 after extending it next time.

[0024] The disengagement member 7 includes a disengagement hole 71 formed on the outer side of the fork 23, the disengagement hole 71 is connected to the clamping hole 64, a spring 3 72 is fixedly connected to the bottom of the disengagement hole 71, a disengagement plate 73 is fixedly connected to one end of the spring 3 72 away from the bottom of the disengagement hole 71, the disengagement plate is located inside the disengagement hole 71 and is slidably connected to the disengagement hole 71, a fixed rod 74 is fixedly connected to one end of the disengagement plate 73 away from the spring 3 72, a disengagement rod 75 is rotatably connected to the outer periphery of the fixed rod 74, and the disengagement rod 75 is located inside the clamping hole 64; When the fork 23 is inserted into the socket 12, since the end of the disengagement plate 73 away from the spring three 72 is fixedly connected with the trigger rod 77, the trigger rod 77 is located at the end of the disengagement rod 75 away from the lifting plate 45, the trigger rod 77 is located in the disengagement hole 71 and is slidably connected to the disengagement hole 71, and the end of the trigger rod 77 away from the disengagement plate 73 is arc-shaped. The trigger rod 77 first abuts against the inner wall of the socket 12 and retracts into the disengagement hole 71. When the trigger rod 77 slides, it squeezes the spring three 72 through the disengagement plate 73. At this time, the spring three 72 accumulates force. When the trigger rod 77 moves to the horizontal position of the socket 12, the spring three 72 is reset, and the spring three 72 lifts the trigger rod 77 through the disengagement plate 73. At the same time, the disengagement plate 73 drives the fixed rod 74 to move When the spring 72 is released, the disengagement rod 75 moves in the opposite direction of the partition 76, and the disengagement rod 75 moves to the inside of the engaging hole 64 and hits the engaging block 63, pushing the engaging block 63 into the engaging groove 61, and the limiting plate 44 is disengaged from the engaging hole 64, and the limiting plate 44 drives the lifting plate 45 to extend through the spring 1 43, so as to facilitate the auxiliary fork 23 to lift and carry the pallet 11; When the fork 23 is pulled out of the transport pallet 11, since the lifting plate 45 is inclined at one end away from the limiting plate 44, the lifting plate 45 tends to descend toward the transport vehicle body 1. When the fork 23 is pulled out, the inclined surface of the lifting plate 45 first touches the inner wall of the insertion hole 12, and the lifting plate 45 gradually retracts into the sliding groove 41. When the limiting groove 42 moves to the position of the locking hole 64, the locking block 63 slides out of the locking groove 61 through the spring 62 and extends into the inside of the locking hole 64, so that the lifting plate 45 can be retracted into the sliding groove 41, which is convenient for the next auxiliary fork 23 to fork the transport pallet 11, and is very convenient to use.
