Description

Technical Field

[0001] This utility model relates to the technical field of three-way vehicles, and specifically to a fork assembly. Background Technology

[0002] With increasing requirements for the fork's lifting range, most forklifts now use three-way forks, meaning the forks can lift, slide horizontally, and tilt to increase the lifting range. However, to prevent the forks from derailing, limiters are usually installed at each extreme position of the movement. But using limiters for mechanical limiting can cause the forks to stop abruptly in the event of an impact, resulting in violent shaking of the forks and poor stability of the goods on the forks. Utility Model Content

[0003] This utility model addresses the aforementioned problems and aims to provide a fork assembly and a three-way vehicle. Through photoelectric sensors, the lateral drive components can be controlled to decelerate and stop sequentially, ensuring the stability of the lateral movement of the fork assembly. Simultaneously, through angle sensors, the rotary motor can be controlled to ensure the stability of the rotation and tilting movements of the fork assembly.

[0004] To achieve the above objectives, this utility model provides a fork assembly, comprising:

[0005] A lateral movement assembly includes a lateral movement frame, a mounting frame, a lateral movement drive, and a lateral movement detection unit. The mounting frame is movably connected to the lateral movement frame. The lateral movement drive is fixed inside a first side of the mounting frame and is used to drive the mounting frame to move laterally along the lateral movement frame. Detection elements adapted to the lateral movement detection unit are provided on the inner sides of both ends of the lateral movement frame. The lateral movement detection unit is fixed to the first side of the mounting frame and is electrically connected to the lateral movement drive.

[0007] A fork assembly connected to the output end of the rotary drive;

[0008] The detection element has a first end near the middle of the transverse frame and a second end near the end of the transverse frame. When the transverse detection unit is opposite to the first end of the detection element, the transverse detection unit can control the transverse drive unit to decelerate. When the transverse detection unit is opposite to the second end of the detection element, the transverse detection unit can control the transverse drive unit to stop moving.

[0009] According to the fork assembly described above, the detection component is a metal bar, and the lateral movement detection unit is a photoelectric sensor, which is used to identify the position signal of the metal bar.

[0010] According to the fork assembly described above, the traverse drive includes a traverse motor and a traverse gear. The traverse motor is fixed in the mounting bracket, and the traverse bracket is provided with a traverse rack arranged laterally. The traverse gear is connected to the output shaft of the traverse motor and meshes with the traverse rack.

[0011] According to the fork assembly described above, two transverse racks are arranged at the upper and lower ends of the inner side of the transverse frame, and two transverse gears are rotatably fixed on the first side of the mounting frame through a first drive shaft and respectively mesh with the two transverse racks. The output shaft of the transverse motor is provided with a first drive gear, which meshes with one of the transverse gears.

[0012] According to the fork assembly described above, the traverse drive also includes guide wheels. Two sets of guide wheels are respectively arranged at the upper and lower ends of the first side of the mounting frame. The two sets of guide wheels can respectively abut against the upper and lower ends of the outer side of the traverse frame and respectively cooperate with the two traverse gears to clamp the traverse frame.

[0013] According to the fork assembly described above, the rotating component further includes a rotation detection unit. The rotating drive component includes a rotary motor, a transmission wheel set, and a second transmission shaft. The rotary motor is connected to the second transmission shaft through the transmission wheel set. The fork assembly is fixedly connected to the second transmission shaft. The rotation detection unit is located at the top of the second transmission shaft and is used to detect the rotation angle of the second transmission shaft.

[0014] According to the fork assembly described above, the rotation detection unit is configured as an angle sensor, which can be electrically connected to the rotary motor.

[0015] According to the above-described fork assembly, the fork assembly includes a fork carriage and two forks fixed on symmetrical sides of the fork carriage. The fork carriage is connected to the second drive shaft via a fixed seat, and a buffer block is provided on the side of the fork carriage near the mounting frame, the buffer block being able to abut against the mounting frame.

[0016] According to the fork assembly described above, the transmission wheel set includes a second transmission gear, a third transmission gear, a fourth transmission gear, and a fifth transmission gear.

[0021] The fork assembly described above is height-adjustable and mounted on the mast assembly.

[0022] This utility model has the following beneficial effects:

[0023] 1. The first and second ends of the detection component can be detected by the lateral movement detection unit. When the first end of the detection component is opposite to the first end of the detection component, it proves that the mounting frame is close to moving to the end of the lateral movement frame. At this time, the first lateral movement detection unit can control the lateral movement drive to decelerate, which can reduce the moving speed of the mounting frame. Then, when the lateral movement detection unit is opposite to the second end of the detection component, it proves that the mounting frame has moved to the end of the lateral movement frame. It controls the lateral movement drive to stop, and the mounting frame also stops moving to avoid the mounting frame derailing. Due to the previous deceleration, sudden stop can be avoided, which can ensure the stability of the fork assembly during lateral movement.

[0024] 2. The rotation detection unit can detect the rotation angle of the second drive shaft. Since the rotation angle of the second drive shaft is the same as the rotation angle of the fork assembly, when the fork assembly is about to approach the mounting frame, the rotation drive can be controlled to decelerate, avoiding violent impact between the fork assembly and the mounting frame, and improving the stability of the goods on the fork assembly.

[0025] 3. A buffer block is provided on the side of the fork carriage closest to the mounting frame. When the fork carriage collides with the mounting frame, the buffer block contacts the mounting frame first, which can play a buffering role and reduce the shaking of the fork assembly.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] like Figure 1-4 As shown, a fork assembly includes a lateral movement component 100, a rotation component 200, and a fork assembly 300. The lateral movement component 100 is used to drive the rotation component 200 and the fork assembly 300 to move laterally, while the rotation component 200 is used to drive the fork assembly 300 to rotate and tilt, thereby meeting the multi-directional movement requirements of the fork assembly 300.

[0038] Specifically, the lateral movement assembly 100 includes a lateral movement frame 110, a mounting frame 120, a lateral movement drive 130, and a lateral movement detection unit 140. The mounting frame 120 is movably connected to the lateral movement frame 110, and the rotating assembly 200 is mounted on the mounting frame 120. The fork assembly 300 is connected to the output end of the rotating drive 210. The displacement of the mounting frame 120 on the lateral movement frame 110 can drive the rotating assembly 200 and the fork assembly 300 to move synchronously. To achieve the displacement of the mounting frame 120 on the lateral movement frame 110, the lateral movement... The drive component 130 is fixed inside the first side of the mounting bracket 120. It is used to drive the mounting bracket 120 to move laterally along the transverse frame 110. That is, the movement of the mounting bracket 120 is controlled by the transverse drive component 130. In order to ensure the smooth movement of the mounting bracket 120, detection components 111 adapted to the transverse detection unit 140 are provided on the inner sides of both ends of the transverse frame 110. The inner side of the transverse frame 110 refers to the side of the transverse frame 110 close to the mounting bracket 120. The transverse detection unit 140 is fixed to the first side of the mounting bracket 120 and is connected to the transverse detection unit 140. When the transverse drive unit 130 is electrically connected, the transverse detection unit 140 can move together with the mounting frame 120. When it moves with the mounting frame 120 to the end of the transverse frame 110, the transverse detection unit 140 will be opposite to the detection element 111. In this embodiment, the detection element 111 has a first end near the middle of the transverse frame 110 and a second end near the end of the transverse frame 110. When the transverse detection unit 140 is opposite to the first end of the detection element 111, it indicates that the mounting frame 120 has approached and moved to the end of the transverse frame 110. The first lateral movement detection unit 140 can control the lateral movement drive 130 to decelerate, which can gradually reduce the moving speed of the mounting frame 120. Then, when the lateral movement detection unit 140 is opposite to the second end of the detection element 111, it proves that the mounting frame 120 has moved to the end of the lateral movement frame 110. It controls the lateral movement drive 130 to stop, and the mounting frame 120 also stops moving to avoid the mounting frame 120 derailing. Due to the previous deceleration, sudden stop can be avoided, and the stability of the fork assembly 300 in the lateral movement can be guaranteed.

[0039] Of course, the detection component 111 is provided with an iron bar, which is arranged laterally on the transverse frame 110. The transverse detection unit 140 is a photoelectric sensor. In this embodiment, the size of the first end of the iron bar is smaller than the size of the second end. That is, when the photoelectric sensor detects the iron bar, it can easily determine the location of the iron bar and identify the position signal of the iron bar. After identifying the position signal, it can send a corresponding control signal to the transverse drive component 130 to control the transverse drive component 130 to perform the corresponding action.

[0040] Furthermore, in order to achieve the displacement of the mounting bracket 120 on the transverse frame 110, the transverse drive component 130 includes a transverse motor 131 and a transverse gear 132. The transverse motor 131 is fixed inside the mounting bracket 120, and the transverse frame 110 is provided with a transverse rack 112 arranged in the transverse direction. The transverse gear 132 is connected to the output shaft of the transverse motor 131 and meshes with the transverse rack 112. That is, the transverse motor 131 drives the transverse gear 132 to rotate. Through the meshing and rolling of the transverse gear 132 on the transverse rack 112, the displacement of the mounting bracket 120 can be achieved.

[0041] Furthermore, to ensure the stability of the movement of the mounting frame 120, two transverse racks 112 are arranged at the upper and lower ends of the inner side of the transverse frame 110. Two transverse gears 132 are rotatably fixed to the first side of the mounting frame 120 through the first transmission shaft 133 and respectively mesh with the two transverse racks 112. The output shaft of the transverse motor 131 is provided with a first transmission gear 131a, which meshes with one of the transverse gears 132. The transverse motor 131 drives the first transmission gear 131a to rotate, and the first transmission gear 131a drives the transverse gear 132 meshing with it to rotate. The transverse gear 132 can drive the first transmission shaft 133 to rotate, and the first transmission shaft 133 will drive the other transverse gear 132 to rotate synchronously, thereby realizing simultaneous driving on both the upper and lower sides and ensuring the stability of the movement of the mounting frame 120.

[0042] Furthermore, to ensure the stability of the assembly between the mounting bracket 120 and the transverse frame 110, the transverse drive component 130 also includes guide wheels 134. Two sets of guide wheels 134 are respectively arranged at the upper and lower ends of the first side of the mounting bracket 120. The two sets of guide wheels 134 can respectively abut against the upper and lower ends of the outer side of the transverse frame 110 and cooperate with two transverse gears 132 to clamp the transverse frame 110. That is, the upper and lower ends of the transverse frame 110 can be clamped at the same time to prevent the mounting bracket 120 from falling off the transverse frame 110. Similarly, the rolling clamping of the guide wheels 134 can avoid interference caused by the movement of the mounting bracket 120.

[0043] Specifically, the rotating assembly 200 includes a rotating drive 210 and a rotating detection unit 220 mounted on the second side of the mounting bracket 120. The rotating drive 210 and the lateral drive 130 are located on opposite sides of the mounting bracket 120 to avoid mutual interference. The rotating drive 210 includes a rotating motor 211, a transmission wheel set, and a second transmission shaft 212. The rotating motor 211 is connected to the second transmission shaft 212 via the transmission wheel set. The fork assembly 300 is fixedly connected to the second transmission shaft 212. The rotating detection unit 220 is located on top of the second transmission shaft 212 and is used to detect the rotation angle of the second transmission shaft 212. The rotary motor 211 drives the second drive shaft 212 to rotate via the transmission wheel set. The second drive shaft 212 can drive the fork assembly 300 to rotate synchronously. The rotation angle of the fork assembly 300 and the second drive shaft 212 are the same. The rotation detection unit 220 detects the rotation angle of the second drive shaft 212 and can determine the rotation angle of the fork assembly 300. When it determines that the fork assembly 300 is about to reach its limit position, it can control the rotary motor 211 to decelerate to avoid violent impact between the fork assembly 300 and the mounting frame 120 and improve the stability of the fork assembly 300 during rotation.

[0044] Furthermore, the rotation detection unit 220 is configured as an angle sensor, which can be electrically connected to the rotary motor 211 and can be used to send signals to the rotary motor 211 to control the rotary motor 211 to perform deceleration.

[0045] Furthermore, the transmission gear set includes a second transmission gear 213, a third transmission gear 214, a fourth transmission gear 215, and a fifth transmission gear 216. The second transmission gear 213 is located on the output shaft of the rotary motor, and the fifth transmission gear 216 is located on the second transmission shaft 212. The third transmission gear 214 and the fourth transmission gear 215 are coaxially arranged, and the third transmission gear 214 meshes with the second transmission gear 213, while the fourth transmission gear 215 meshes with the fifth transmission gear 216. That is, the rotary motor drives the second transmission gear 213 to rotate through the output shaft, and the second transmission gear 213 drives the third transmission gear 214 to rotate. Since the third transmission gear 214 and the fourth transmission gear 215 are coaxially arranged, when the third transmission gear 214 rotates... When in motion, the fourth transmission gear 215 rotates synchronously, which in turn drives the fifth transmission gear 216 to rotate, thereby driving the second transmission shaft 212 to rotate. The second transmission shaft 212 drives the fork assembly 300 to rotate. The diameter of the second transmission gear 213 is smaller than that of the third transmission gear 214, and the diameter of the fourth transmission gear 215 is smaller than that of the fifth transmission gear 216. When the second transmission gear 213 drives the third transmission gear 214 to rotate, it can have a deceleration effect. When the fourth transmission gear 215 drives the fifth transmission gear 216 to rotate, it can also have a deceleration effect. This can achieve a two-stage deceleration from the motor to the fork assembly 300, preventing the fork assembly 300 from rotating too fast and improving safety performance.

[0046] In this embodiment, the power units of the transverse drive 130 and the rotary drive 210 are both electric motors, which have higher control precision and faster response speed compared to conventional hydraulic drives.

[0047] Specifically, the fork assembly 300 includes a fork carriage 310 and two forks 320 fixed on both sides of the fork carriage 310. The fork carriage is connected to the second drive shaft 212 through a fixed seat. A buffer block is provided on the side of the fork carriage 310 near the mounting frame 120. The buffer block can abut against the mounting frame 120. When the fork carriage 310 rotates to the side near the mounting frame 120, the buffer block is the first to contact the mounting frame 120. It can play a role in buffering and decelerating, thereby avoiding violent impact between the fork carriage 310 and the mounting frame 120, and further improving the stability of the fork assembly 300 during rotation.

[0048] A three-way vehicle includes a body 400, a mast assembly, and the aforementioned fork 320 assembly. The mast assembly is located on the front side of the body 400, and the fork 320 assembly is mounted on the mast assembly in a height-adjustable manner to realize the lifting and lowering action of the forks 320.

[0049] In this embodiment, a fork assembly 320 and a three-way vehicle are disclosed. The fork assembly 320 includes a lateral movement component 100, a rotation component 200, and a fork assembly 300. The lateral movement component 100 includes a lateral movement frame 110, a mounting frame 120, a lateral movement drive component 130, and a lateral movement detection unit 140. The mounting frame 120 is movably connected to the lateral movement frame 110, and the rotation component 200 is mounted on the mounting frame 120. The fork assembly 300 is connected to the output end of the rotation drive component 210. The mounting frame 120 is movably connected to the lateral movement frame 110, and the lateral movement drive component 130 is fixed inside the first side of the mounting frame 120 and is used for driving... The movable mounting bracket 120 moves laterally along the transverse frame 110. The inner sides of both ends of the transverse frame 110 are provided with detection elements 111 that are adapted to the transverse detection unit 140. The transverse detection unit 140 is fixed on the first side of the mounting bracket 120 and is electrically connected to the transverse drive unit 130. When the transverse detection unit 140 is opposite to the first end of the detection element 111, the transverse detection unit 140 can control the transverse drive unit to decelerate. When the transverse detection unit 140 is opposite to the second end of the detection element 111, the transverse detection unit 140 can control the transverse drive unit to stop moving, which can improve the smoothness of the transverse movement of the fork assembly 300.
