Description

Technical Field

[0001] The utility model relates to the field of forklift lifting, in particular to an intelligent forklift electric lifting structure. Background Art

[0002] Smart forklifts combine barcode technology, wireless LAN technology, and data collection technology to form a field operation system. Their main purpose is to extend the enterprise management system to the operator's hands or on the forklift, making their work more convenient and the system more intelligent. Equipping the forklift with a wireless vehicle-mounted terminal allows the operation to be guided by information. This is the concept of a smart forklift.

[0003] Existing intelligent forklifts are mainly composed of a body, a hydraulic mechanism, an electronic module, a driving mechanism, a lifting mechanism, a fork mechanism, etc. When in use, the fork mechanism is lowered to the bottom, and the body is moved to shovel the material onto the fork mechanism. Then the body can be moved, and finally the lifting mechanism can drive the fork mechanism and the material to rise. When the material reaches the required position, it can be pushed out to discharge the material for stacking. Most of the existing intelligent forklifts have two methods: rearward moving the fork mechanism to disengage the material and manual unloading. However, the rearward moving fork mechanism can only be disengaged from the material when the bottom of both sides of the material is lower than the fork mechanism, which is convenient for the fork mechanism to insert or withdraw. It has certain limitations in use, and manual unloading is time-consuming and labor-intensive, and has low efficiency.

[0004] Therefore, it is necessary to invent an intelligent forklift electric lifting structure. Utility Model Content

[0005] The purpose of this utility model is to solve the problems raised in the above background technology.

[0007] The fork tine assembly includes a first fork tine and a second fork tine, the second fork tine is located on both sides of the first fork tine, and a limiting groove is provided on one side of the second fork tine.

[0008] Based on the above features: when the first fork tine and the second fork tine are at the bottom, once the machine body is pushed toward the material, the material can be shoveled above the first fork tine and the second fork tine. At this time, the pushing assembly will be attached to one side of the fixed plate. When the lifting screw is adjusted forward or reverse, the fixed plate and the fork tine assembly can be driven to rise and fall on one side of the gantry, which is convenient for lifting and stacking the material on the fork tine assembly. When the material is lifted to the required position for discharge, the pushing assembly can be driven to move. At this time, the pushing assembly can be guided by the limit slot to move to the side away from the fixed plate, which is convenient for pushing out the material on the first fork tine and the second fork tine. It is simple and convenient.

[0009] Preferably, guide grooves are symmetrically provided on both sides of the outer wall of the gantry.

[0010] Based on the above features: when the fixed plate and the fork tine assembly are raised and lowered, the guide slots can be used to guide and limit the fixed plate and the fork tine assembly, so as to facilitate the vertical lifting of the fixed plate and the fork tine assembly.

[0011] Preferably, a locking nut is fixedly installed in the middle of one side of the fixing plate, connecting plates are symmetrically installed on both sides of the upper end of the fixing plate, and a guide slider is installed at one end of the connecting plate.

[0015] Preferably, a positioning block is fixedly installed on the outside of the movable nut, and plug plates are symmetrically installed on both sides of the positioning block, and fixing holes are opened on the surface of the plug plates.

[0016] Based on the above features: the positioning block is limited inside the movable groove, and the two sides of the positioning block are connected to the bottom end of the pushing component through the plug plate and the fixing hole, which makes it convenient for the movable nut to drive the pushing component to move through the positioning block and the plug plate, and at the same time facilitates the disassembly and assembly of the plug plate and the pushing component.

[0017] Preferably, the pushing assembly includes a base and a push plate fixedly installed on the upper end of the base, a slot is provided on one side of the push plate, and threaded holes are symmetrically provided on both sides of the slot.

[0018] Based on the above characteristics: when the material is above the fork tine assembly, the base can drive the push plate to move to one side and fit the surface of the fixed plate. When the material needs to be pushed out, the movable nut can drive the base and the push plate to move. At this time, the movable push plate can move to the side away from the fixed plate, thereby pushing out the material above the fork tine assembly.

[0019] Preferably, a telescopic slot is provided on a side of the base away from the slot, a limiting slider is installed inside the telescopic slot, a compression spring is installed at one end of the limiting slider, and a pull plate is installed on the side of the end of the limiting slider close to the compression spring.

[0020] Based on the above features: when the limit slider extends outward, the limit slider can be stuck in the limit slot, and when the base and the push plate move and adjust, the limit slider can slide guidedly in the limit slot, so that the base and the push plate maintain stable translation.

[0021] Preferably, the drive assembly includes a protective box and a drive motor installed inside the protective box, a turbine is installed at the output end of the drive motor, one end of the turbine is meshed with a worm, and one end of the worm has a transmission shaft.

[0022] Based on the above characteristics: the rotating shaft at the output end of the driving motor is connected to the turbine. When the turbine is adjusted to rotate forward or reverse, the transmission shaft can be driven to rotate through the worm. The transmission shaft is connected to one end of the adjusting screw. When the transmission shaft rotates, the adjusting screw can be driven to rotate synchronously.

[0023] The beneficial effects of the utility model are:

[0024] 1. When the material is above the first fork tine and the second fork tine, the push plate will be located on one side surface of the fixed plate. When the machine body moves to stack the material, the lifting screw is driven to rotate. At this time, the locking nut can drive the fork tine assembly and the material to be lifted to the position where stacking is required through the fixed plate. Then the driving assembly can drive the adjusting screw to rotate. As the adjusting screw rotates, the movable nut on its outside can drive the positioning block to move, and the positioning block can drive the push plate to move through the base. Finally, the moving push plate can push out the material above the first fork tine and the second fork tine.

[0025] 2. The positioning block is limited inside the movable slot, and the two sides of the positioning block are inserted into the slot at one end of the base through the plug-in plate. At this time, the fixing hole and the threaded hole are aligned, and then the bolts are passed through and locked to facilitate the movable disassembly and assembly between the positioning block and the base. At the same time, the other end of the base can be inserted into the limit slot using the limit slider. When the base and the push plate are moved and adjusted, the limit slider can be guided and slid inside the limit slot to keep the base and the push plate stable in translation.

When the motor drives the gear at the output end to rotate, the rotating gear can drive the gear at the bottom of the lifting screw 3 to rotate. At this time, the lifting screw 3 will also rotate synchronously. It is not shown in the figure because it is blocked by the body 1. It is also an existing driving means, so it is not shown. It is hereby explained). A fixing plate 4 is provided on one side of the gantry 2, and a fork tine assembly 5 is fixedly installed at the lower end of the fixing plate 4 away from the gantry 2.

A universal wheel is set at the lower end of the body 1 to facilitate the movement and direction adjustment of the body 1. When the first fork 51 and the second fork 52 are at the bottom, once the body 1 is pushed toward the material, the material can be shoveled onto the first fork 51 and the second fork 52. At this time, the pushing component 6 will be attached to one side of the fixed plate 4. When the lifting screw 3 is adjusted forward or reverse, it can drive the fixed plate 4 and the fork component 5 to rise and fall on one side of the gantry 2, which is convenient for lifting and stacking the material on the fork component 5. When the material is lifted to the required position for discharge, the pushing component 6 can be driven to move.

[0044] When the material is above the fork tine assembly 5, the base 61 can drive the push plate 62 to move to one side and fit into the surface of the fixed plate 4. When the material needs to be pushed out, the movable nut 513 can drive the base 61 and the push plate 62 to move. At this time, the movable push plate 62 can move to the side away from the fixed plate 4, so that the material above the fork tine assembly 5 can be pushed out. One end of the base 61 is connected to the insert plate 5132 through the slot 63. When the two are connected, the fixing hole 5133 and the threaded hole 64 can be aligned, and finally they can be connected by bolts.

When the turbine 73 is adjusted to rotate forward or reverse, the transmission shaft 75 can be driven to rotate through the worm 74. The transmission shaft 75 is connected to one end of the adjusting screw 512. When the transmission shaft 75 rotates, the adjusting screw 512 can be driven to rotate synchronously.

[0049] The use process of the present invention is as follows: when the first fork 51 and the second fork 52 are located on one side of the bottom of the fixed plate 4, the body 1 can be pushed toward the material, and the material can be shoveled above the first fork 51 and the second fork 52. At this time, the push plate 62 will be located on one side of the fixed plate 4.

At this time, the locking nut 41 can drive the fork assembly 5 and the material to be lifted to the position where stacking is required through the fixed plate 4, and then the driving motor 72 can be driven. The turbine 73 is driven to rotate through the rotating shaft, and the turbine 73 can drive the adjusting screw 512 to rotate through the worm 74 and the transmission shaft 75. As the adjusting screw 512 rotates, the movable nut 513 on its outside can drive the positioning block 5131 to move, and the positioning block 5131 can drive the push plate 62 to move through the base 61. Finally, the moving push plate 62 can push out the material above the first fork tine 51 and the second fork tine 52. After the material is pushed out, the adjusting screw 512 can be rotated to make the push plate 62 move back and fit onto one side surface of the fixed plate 4.
