Description

Technical Field

[0001] This utility model relates to the field of forks, and more particularly to a telescopic plate fork. Background Technology

[0002] Telescopic pallet forks are flat forks with integrated telescopic function, mainly used in material handling equipment (such as forklifts, stackers, AGVs, etc.). The length can be adjusted by telescopic mechanism to adapt to goods of different sizes or positions (such as long pallets, plates, pipes, etc.).

[0003] In the existing technology, most telescopic pallet forks use a single-pallet telescopic structure to handle goods. This can easily cause the center of gravity of the goods to tilt to one side during handling, resulting in the goods falling off. This makes the handling stability poor. Utility Model Content

[0004] The present invention aims to provide a telescopic plate fork to overcome or at least partially solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows: This utility model provides a telescopic fork, including a support column, a connecting frame sleeved on the support column, and the connecting frame slidably connected to the support column via a guide rail. A first telescopic plate is slidably connected to the connecting frame, and a second telescopic plate is slidably connected to the first telescopic plate. A first servo motor is fixedly installed at the top of the support column, and the output shaft of the first servo motor is connected to a ball screw. The ball screw is inserted into the connecting frame and drives the connecting frame to move along the support column and the ball screw. A second servo motor is also installed on the connecting frame, and the output shaft of the second servo motor is connected to a gear set. The gear set is located inside the connecting frame, and the top of the gear set meshes with a rack through gear teeth. The rack is fixedly installed at the bottom of the first telescopic plate and drives the first telescopic plate to move. A fixing block is also fixedly installed on the connecting frame, and traction ropes are connected to both ends of the fixing block. The other end of the traction rope is fixedly connected to a rope connector, and the rope connector is installed inside the second telescopic plate.

[0006] As a further embodiment of this utility model, the gear set is provided in two sets, which are symmetrically arranged inside the connecting frame, and a coupling is connected between the two sets of gear sets to enable the two sets of gear sets to rotate synchronously.

[0007] As a further embodiment of this utility model, guide rails are fixedly installed on both the left and right sides of the support column, and connecting plates are slidably connected to the guide rails, with the connecting plates being fixedly connected to the connecting frame.

[0008] As a further embodiment of this utility model, a support base is fixedly installed at the top of the support column, and the first servo motor is installed on the support base.

[0009] As a further embodiment of this utility model, the top of the first telescopic plate is provided with a rope groove, the rope joint is disposed in the rope groove, and guide wheels are provided on the left and right sides of the second telescopic plate, and the traction rope passes around the guide wheels.

[0010] As a further embodiment of this utility model, both the first telescopic plate and the second telescopic plate are provided with two sets, and the fixing block, the traction rope and the rope joint are provided with four sets. The four sets of traction ropes are symmetrically connected to the connecting frame, and the tractor is used to pull the second telescopic plate to perform reciprocating motion.

[0011] This utility model provides a telescopic forklift, which has the following advantages: by extending and retracting the telescopic plate, goods at a greater distance can be forked out and transferred.

[0019] See Figure 1-4 This utility model provides a telescopic plate fork, including a support column 1, a connecting frame 8 sleeved on the support column 1, and the connecting frame 8 slidably connected to the support column 1 via a guide rail 9. A first telescopic plate 3 is slidably connected to the connecting frame 8, and a second telescopic plate 4 is slidably connected to the first telescopic plate 3. A first servo motor 5 is fixedly installed at the top of the support column 1, and the output shaft of the first servo motor 5 is connected to a ball screw 2. The ball screw 2 is inserted into the connecting frame 8 and drives the connecting frame 8 to move along the support column 1 and the ball screw 2. A second servo motor 10 is also installed on the connecting frame 8. The output shaft of the second servo motor 10 is connected to the gear set 12. The gear set 12 is located inside the connecting frame 8, and the top of the gear set 12 meshes with the rack through the gear teeth. The rack is fixedly installed at the bottom of the first telescopic plate 3 and drives the first telescopic plate 3 to move. A fixing block 13 is also fixedly installed on the connecting frame 8. Both ends of the fixing block 13 are connected to the traction rope 14. The other end of the traction rope 14 is fixedly connected to the rope connector 15. The rope connector 15 is installed inside the second telescopic plate 4.

[0020] Two sets of gears 12 are provided, and the two sets of gears 12 are symmetrically arranged inside the connecting frame 8. A coupling 11 is also connected between the two sets of gears 12 to enable the two sets of gears 12 to rotate synchronously.

[0021] Guide rails 9 are fixedly installed on the left and right sides of the support column 1, and connecting plates 7 are slidably connected to the guide rails 9. The connecting plates 7 are fixedly connected to the connecting frame 8, so that the connecting frame 8 can maintain stability and guidance when moving.

[0022] A support base 6 is fixedly installed at the top of the support column 1, and the first servo motor 5 is installed on the support base 6, thereby fixing the first servo motor 5 through the support base 6.

[0023] The top of the first telescopic plate 3 is provided with a rope groove, and the rope joint 15 is set in the rope groove. The left and right sides of the second telescopic plate 4 are provided with guide wheels, and the traction rope 14 passes around the guide wheels. The first telescopic plate 3 and the second telescopic plate 4 are each provided with two sets, and the fixing block 13, the traction rope 14 and the rope joint 15 are each provided with four sets. The four sets of traction ropes 14 are symmetrically connected to the connecting frame 8. The tractor is used to pull the second telescopic plate 4 to reciprocate, so that the reciprocating movement of the first telescopic plate 3 can drive the second telescopic plate 4 to reciprocate synchronously.

[0024] In use, the first servo motor 5 drives the ball screw 2 to rotate, which in turn drives the connecting frame 8 to move up and down along the guide rail 9 and the ball screw 2. This, in turn, drives the first telescopic plate 3 and the second telescopic plate 4 to move synchronously. The second servo motor 10 drives the gear set 12 to rotate, and the coupling 11 ensures that the two gear sets 12 rotate synchronously in the same direction. Through the meshing of the gear set 12 with the gear, the first telescopic plate 3 can be driven to move to the left or right, and the traction rope 14 can synchronously drive the second telescopic plate 4 to move to the left or right, thus achieving the purpose of double extension.
