[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Please see Figures 1 to 3 The utility model is a telescopic fork which can rotate at multiple angles in a lane, and comprises a fixed part 1, a mobile frame 2 which moves along the fixed part 1, a steering mechanism 3 installed at the end of the mobile frame 2, and a fork 4 driven by the steering mechanism 3.
[0025] Please see Figure 1 The fixing part 1 includes a fixing plate 11, a track 12 and a rack 13 installed on the surface of the fixing plate 11. The fixing plate 11 is perpendicular to the horizontal plane. The track 12 is a pair, extending from one end of the fixing plate 11 to the other end thereof. The rack 13 is located between the pair of tracks 12, extending from one end of the fixing plate 11 to the other end thereof.
[0026] Please see Figure 1 to Figure 2 The movable frame 2 includes a frame body 21 and a linear motor 22 installed on the frame body 21. A movable plate 23 is fixedly installed at one end of the frame body 21. A slider 24 is fixedly installed on the surface of the movable plate 23. The slider 24 is movably connected to the track 12. The linear motor 22 is located at the top of the frame body 21. It has a driving shaft 221 and a driving gear 222 sleeved on the driving shaft 221. The driving shaft 221 penetrates the frame body 21 and extends vertically downward. It is driven by the linear motor 22 to drive the driving gear 222 to rotate synchronously.
[0027] Please see Figure 2 A speed reducer 25 is provided on one side of the driving gear 222. The speed reducer 25 includes a driven shaft 251 and a driven gear 252 sleeved on the driven shaft 251. The driven shaft 251 is fixedly installed on the inner side of the frame 21 and is arranged relatively parallel to the driving shaft 221. One side of the driven gear 252 is on the same horizontal line as the driving gear 222 and meshes with the driving gear 222. The other side of the driven gear 252 is on the same horizontal line as the rack 13 and meshes with the rack 13. Secondly, a bearing is provided between the driven shaft 251 and the driven gear 252.
[0028] The linear motor 22 drives the driving gear 222 to rotate via the driving shaft 221 , and the driving gear 222 drives the driven gear 252 to rotate synchronously. Since the driven gear 252 meshes with the rack 13 , the moving frame 2 is driven to move horizontally along the rack 13 and the track 12 as a whole.
[0029] Please see Figure 1 and Figure 3The steering mechanism 3 includes a steering motor 31, a central shaft 32 driven by the steering motor 31, and a steering sleeve 33 sleeved with the central shaft 32. The steering motor 31 is located at the top of the frame 21, and a reducer 34 is connected to its end. The reducer 34 is used to reduce the rotation speed output by the steering motor 31. One end of the central shaft 32 extends into the reducer 34, and the other end thereof extends vertically downward. The steering sleeve 33 moves synchronously with the central shaft 32, and a follower plate 36 is provided at both the upper and lower ends thereof. One end of the follower plate 36 is fixedly connected to the steering sleeve 33, and the other end thereof extends horizontally outward. A docking plate 35 is installed at the end of the follower plate 36, and the docking plate 35 moves synchronously with the follower plate 36.
[0030] The steering motor 31 drives the steering sleeve 33 to rotate through the central shaft 32 , and the steering sleeve 33 drives the follower plate 36 and the docking plate 35 to rotate synchronously at a certain angle around the central shaft 32 .
[0031] The cargo fork 4 is mounted on the docking plate 35 and is used for lifting cargo.
[0032] When the telescopic fork capable of rotating at multiple angles in a lane is used, the linear motor 22 drives the driving gear 222 to rotate through the driving shaft 221, and the driving gear 222 drives the passive gear 252 to rotate synchronously. Since the passive gear 252 is meshed with the rack 13, the moving frame 2 is driven to move horizontally along the rack 13 and the track 12 as a whole. After moving to a predetermined position, according to demand, the steering motor 31 drives the steering sleeve 33 to rotate through the central shaft 32, and the steering sleeve 33 drives the follower plate 36 and the docking plate 35 to rotate synchronously at a certain angle with the central shaft 32 as the center, so that the fork 4 is accurately adjusted to a corresponding angle with the central shaft 32 as the center, thereby changing the position of the fork 4.
[0033] The utility model is a telescopic fork which can be rotated at multiple angles in lanes and has the characteristic of high adaptability. A linear motor drives the moving frame to move horizontally as a whole, and a steering motor drives the follower plate and the docking plate to synchronously rotate at a certain angle around the central axis, so that the fork can be accurately adjusted to the corresponding angle, adapting to different working environments and improving adaptability.
