Example one

A fork tool, as shown in fig. 1-3, which specifically comprises a fork tool holder 1, a fork knife 2, a lockable telescopic rod 4 and a fork knife driving mechanism 5.

The forklift frame 1 is a flat plate, and one side of the back surface of the forklift frame is used for being connected with a forklift, for example, fixedly connected through bolts. Generally, since the pitching arm of the forklift truck has a high and low pitching function, the fork mounted on the pitching arm needs to be adjusted in a pitching angle, in this embodiment, the back surface of the forklift truck 1 is provided with a pin hole or a pin shaft arranged in a horizontal direction, so that after the pitching arm angle changes, the fork can restore the original horizontal position by rotating in a reverse direction with the pitching arm of the forklift truck, for example, in this embodiment, it is preferable that pin shaft seats 11 are provided on both the upper part and the lower part of the back surface of the forklift truck 1, pin holes for the pin shaft to pass through are provided on the pin shaft seats 11, and the forklift truck is connected with the forklift truck 1 through the pin shaft seats 11. For the forklift truck without pitching operation, in one embodiment, the forklift truck 1 only needs to be provided with a bolt hole or a fixture block clamping groove structure, and the back of the forklift truck 1 can be fixedly connected to the forklift truck.

The two fork knives 2 are connected to the same side (the front side) of the fork knife rest 1 in a sliding mode, and the sliding directions of the two fork knives 2 are parallel to each other. In the present embodiment, the fork blade 2 slides in the horizontal direction (i.e. the left-right direction), and is parallel to the front surface of the fork blade holder 1, and two fork blades 2 are arranged oppositely along the horizontal direction, so that the two fork blades 2 can move in the same direction, for example, the operation of moving the two fork blades 2 laterally integrally, or move in the opposite direction, for example, the operation of increasing or decreasing the distance between the two fork blades 2 can be performed. In addition, in the present embodiment, the front surface of the fork tool holder 1 is fixedly provided with the guide slide rail 6, the fork tool 2 includes the sliding body 21 and the cutter body 22 fixed at the lower part of the sliding body 21, and the sliding body 21 is provided with the guide sleeve 7 adapted to the guide slide rail 6, so that the whole fork tool 2 can slide along the guide slide rail 6, thereby realizing the sliding connection between the fork tool 2 and the fork tool holder 1. And the further setting fork blade 2 (specifically, the sliding body 21) of this embodiment has a certain length in the direction perpendicular to the sliding direction (i.e., the up-down direction), so that one guide sleeve 7 is respectively disposed on the upper portion and the lower portion of the sliding body 21, and a corresponding number of guide slide rails 6 are disposed at corresponding positions on the front side of the fork blade holder 1, thereby improving the sliding stability of the fork blade 2 and preventing the fork blade 2 from rotating on the guide slide rails 6.

The lockable telescopic part 4 is connected between the two fork knives 2, when the distance between the two knife bodies 22 needs to be adjusted, the locking state of the lockable telescopic part 4 can be unlocked, and when the distance between the two knife bodies 22 is adjusted, the lockable telescopic part 4 can be locked. In this embodiment, the lockable telescopic part 4 comprises a first connecting rod 41, a second connecting rod 42 and a locking screw 43, one end of the first connecting rod 41 is inserted into one end of the second connecting rod 42, the other end of the first connecting rod 41 is fixedly connected to one of the two fork blades 2 (specifically, the sliding body 21), and the other end of the second connecting rod 42 is fixedly connected to the other of the two fork blades 2 (specifically, the sliding body 21). Meanwhile, an axial through groove 44 is formed in a side wall of the second link 41, a threaded hole is formed in a side wall of the second link 42, and one end (end having an external thread) of the locking screw 43 is screwed into the threaded hole after passing through the axial through groove 44. When locking is required, the second connecting rod 42 can be clamped through the screwing parts of the first connecting rod 41 and the locking screw 43 only by screwing the other end (the end with the screwing part) of the locking screw 43, which is positioned outside the axial through groove 44, and the first connecting rod 41 and the second connecting rod 42 cannot move relatively by increasing friction force; when the locking is required to be released, the locking screw 43 is reversely screwed, the first connecting rod 41 and the second connecting rod 42 can move relatively, and at the moment, the locking screw 43 moves in the axial through groove 44.

In one embodiment, the threaded holes and locking screws described above can also be replaced by studs fixed to the side wall of the first link 41 and having the other end of the stud pass through the axial through slot 44 in the side wall of the second link 42, and locking nuts screwed onto the other end of the stud passing through the axial through slot 44.

The fork knife driving mechanism 5 is connected between the fork knife holder 1 and the fork knife 2 (specifically, the sliding body 21) to drive the two fork knives 2 to move in the same direction or in the opposite direction. For example, the fork-knife drive mechanism 5 may comprise two linear drive mechanisms 51, one linear drive mechanism 51 described above being connected between each fork knife 2 and the fork knife holder 1, i.e. the linear drive mechanism 51 is mounted on the fork knife holder 1 at one end and on the fork knife 2 at the other end. In the present embodiment, the linear driving mechanism 51 is preferably a hydraulic cylinder, and in another embodiment, may be a driving mechanism having a linear reciprocating structure, such as an electric cylinder or an air cylinder.

It will be appreciated that since there is typically some spacing between the forks 3 and hence the fork carriage 1 between the forks 2, the present embodiment preferably mounts the fork drive mechanism 5, i.e., the linear drive mechanisms 51, described above on the fork carriage 1 between the forks 2.

When the fork tool is used, the distance between the fork tools 2 is adjusted in advance for goods with fixed fork loading holes such as trays, the two linear driving mechanisms 51 work (namely extend or shorten) during adjustment to drive the two fork tools 2 to move in opposite directions, so that the distance between the fork tools 2 is changed, the two linear driving mechanisms 51 stop working until the distance between the fork tools 2 reaches a proper value, at the moment, the distance between the two fork tools 2 can be fixed through locking of the lockable telescopic part 4, and the goods can be loaded by the fork tool after the distance between the fork tools 2 is adjusted; when the placement position of the goods deviates to make the knife body 22 of the fork knife 2 unable to fork, the two linear driving mechanisms 51 can be controlled to work (one is extended and the other is shortened), so that the two fork knives 2 move in the same direction, that is, the whole fork knife moves laterally, and the fork knives 2 can be forked into the fork holes. Meanwhile, when the bulk materials are loaded in the fork mode, the lockable telescopic piece 4 can be loosened to reduce the distance between the two fork knives 2, and therefore the bulk materials can be forked by the two fork knives 2.

Specifically, as shown in fig. 4 to 6, the fork further includes a bracket 3, and a rear side of the bracket 3 is used for connecting to a forklift, and a structure for connecting to the forklift is the same as that of the fork carriage 1, and is not described again.

The forkhead 1 is rotatably coupled to the bracket 3, and the forkhead 1 has a front surface for mounting the fork 2 and the fork drive mechanism 5 described above. In this embodiment, the forklifts 1 are rotatably connected to the bracket 3 through the slewing bearing.

Meanwhile, a rotary driving mechanism 8 for driving the fork tool rest 1 to rotate relative to the support 3 is arranged between the support 3 and the fork tool rest 1.

In this embodiment, the rotary driving mechanism 8 includes a motor, a driving gear and a fixed gear ring, wherein the fixed gear ring is fixedly mounted on the fork carriage 1, the motor is fixedly mounted on the bracket 3, the driving gear is mounted on an output shaft of the motor, and the driving gear is engaged with the fixed gear ring. So set up for the motor work back, rotate through the driving gear, the fixed ring gear of drive rotates, and then drives fork rest 1 and rotate relative support 3. Meanwhile, in the present embodiment, the rotation driving mechanism 8 includes two motors, and each motor is provided with a driving gear, so that the forklifts 1 are driven to rotate by the two motors.

Alternatively, in another embodiment, the rotary drive mechanism 8 may further comprise a hydraulic cylinder, a rack and a gear ring, wherein the gear ring is fixedly mounted on the fork carriage 1, the hydraulic cylinder is fixedly mounted on the carriage 3, the rack is slidably connected to the carriage 3 through a slide-and-slide structure, and the rack is configured to engage with the gear ring. Thereby, the rack is deduced to move through the hydraulic oil cylinder, and the forking tool rest 1 is driven to rotate relative to the bracket 3.

When the forklift is used, when goods incline or the goods need to rotate, the forklift frame 1 and the cutter body 22 can rotate through the rotary driving mechanism 8, so that the forklift is used for forklift loading of the inclined goods and rotation operation of the forklift loaded goods are performed.
