Wherein, the bottom and the supporting leg 3 of fork truck body 1 all are provided with pulley 4, can make things convenient for fork truck to remove.
Referring to fig. 2, the yoke 55 assembly includes a mounting bracket 51, a rotating rod 52, a guide rod 53, two connecting rods 54, and two yokes 55. The dovetail groove 21 is formed in the lifting gantry 2 along the height direction of the lifting gantry 2, the dovetail block 511 is arranged on one side, facing the lifting gantry 2, of the mounting frame 51, and the dovetail block 511 is arranged in the dovetail groove 21 in a sliding mode, so that the mounting frame 51 can be prevented from being separated from the lifting gantry 2.
The cross section of mounting bracket 51 is "U" style of calligraphy, and bull stick 52 rotates and sets up in mounting bracket 51, and wherein one end of bull stick 52 runs through the lateral wall of mounting bracket 51 and extends to the outside of mounting bracket 51, and the bull stick 52 that is located the mounting bracket 51 outside is connected with hand wheel 56, through setting up hand wheel 56, has the effect of being convenient for rotate bull stick 52.
The periphery side symmetry of bull stick 52 is provided with forward screw thread and reverse screw thread, and of two connecting rods 54, one connecting rod 54 and bull stick 52 is through forward screw thread fit, and another connecting rod 54 and bull stick 52 is through reverse screw thread fit, and guide bar 53 is parallel with bull stick 52, and guide bar 53 fixed mounting is on mounting bracket 51, and two connecting rods 54 all pass guide bar 53, and connecting rod 54 and guide bar 53 sliding connection.
Therefore, when the hand wheel 56 is rotated, the two connecting rods 54 are moved toward or away from each other by the guide of the guide rod 53. Since one end of the fork 55 is fixed to the end of the connecting rod 54 remote from the rotating rod 52, when the connecting rods 54 are close to or remote from each other, the two fork 55 are also close to or remote from each other, and the fork 55 can be adapted to trays having different sizes by adjusting the distance between the two fork 55.
In addition, the end of the fork 55 remote from the lifting mast 2 is inclined upwards, which is beneficial to reducing the possibility that the pallet falls off from the side of the fork 55 remote from the mounting frame 51.
When ground is uneven, the fork truck can vibrate easily when transporting the enameled wires, so that the enameled wires placed on the tray can fall off from the tray easily. In order to solve the problem, in this example, the mounting frame 51 is provided with a limiting structure, and the limiting structure is limited on two sides of the tray, so that the possibility that the enameled wire falls off from two sides of the tray can be reduced.
Referring to fig. 2, the limiting structure includes a supporting rod 61, a limiting member and an abutting member.

In this embodiment, the limiting member is specifically a limiting plate 62, the limiting plate 62 is fixedly connected with a sliding plate 63, the sliding plate 63 passes through the guide rod 53 and the support rod 61 at the same time, the sliding plate 63 is connected with the limiting plate 62 in a staggered manner, and the sliding plate 63 drives the limiting plate 62, the guide rod 53 and the support rod 61 to slide along the length direction of the guide rod 53 and the support rod 61. In addition, the abutting pieces are abutting bolts 64, wherein the abutting bolts 64 are in threaded fit with the sliding plates 63, the number of the abutting bolts 64 is four, two of the abutting bolts 64 abut two sliding plates 63 which are oppositely arranged on the guide rod 53, and the other two abutting bolts 64 abut two sliding plates 63 which are oppositely arranged on the support rod 61. When the sliding of the position-limiting plate 62 is required, the tightening bolt 64 is screwed out to a side away from the guide rod 53 or the support rod 61, so that the position-limiting plate 62 can be slid along the length direction of the guide rod 53 or the support rod 61.
In order to prevent the sliding plate 63 from sliding out of the two ends of the guide rod 53 or the support rod 61, in this embodiment, the two ends of the guide rod 53 and the support rod 61 are respectively provided with a retaining block, and the retaining blocks are perpendicular to the guide rod 53 and the support rod 61.
In addition, in this embodiment, the mounting frame 51 is connected to a driving component for driving the mounting frame to drive the fork 55 to ascend or descend. The driving assembly comprises a lifting cylinder 81, a chain wheel 82 and a chain 83 matched with the chain 83. Wherein, the cylinder body of lift cylinder 81 is fixedly installed at the bottom of lift portal 2, and the piston rod of lift cylinder 81 is connected with sprocket 82, and when the piston rod of lift cylinder 81 rises or descends, sprocket 82 rises or descends along with lift cylinder 81. In addition, the chain 83 is driven around the chain wheel 82, wherein one end of the chain 83 is fixed on the forklift body 1, the other end of the chain 83 is fixed on the mounting frame 51, and the mounting frame 51 is slidably connected with the lifting door, so that when the lifting cylinder 81 is started, the chain 83 can drive the fork rod 55 and the limiting plate 62 on the mounting frame 51 to move up and down along the height direction of the lifting door frame 2.
The implementation principle of the embodiment is as follows: during work, the lifting cylinder 81 is started to enable the fork rods 55 to move downwards, and the hand wheel 56 is rotated to adjust the distance between the two fork rods 55 so as to load a tray filled with enameled wires; after the pallet is loaded, the cylinder is started again to enable the fork rod 55 to move upwards for a preset height, so that the fork rod 55 leaves the ground, and the effect of moving the forklift is facilitated; finally, the limiting plates 62 are slid to enable the limiting plates 62 to abut against two opposite sides of the tray, then the abutting bolts 64 are screwed in, the abutting bolts 64 abut against the guide rods 53 and the supporting rods 61, the enameled wire on the tray is limited, and the possibility that the enameled wire falls off from two sides of the tray is reduced.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
