[0003] However, the specifications of the pallets used for different types of goods are different. When forking pallets of different specifications, the position of the forklift's fork arms needs to be adjusted so that the fork arms can be adapted to the forked pallet. Currently, the fork arms are usually connected to the forklift mast through guide rails, and when adjusting the position of the fork arms, it is usually done manually by pushing the fork arms closer to or farther away from another fork arm to adjust the distance between the two fork arms. This adjustment method is rather troublesome.

[0004] Therefore, a new technical solution is needed to solve the above problems. Utility Model Content

Detailed implementation manners

[0043] The following further elaborates on the present application in conjunction with the accompanying drawings.

[0044] A combined fork mechanism for assembling building materials storage disclosed in the present application, as Figure 1 shown, includes a mounting base 1 for being installed on a forklift, and four groups of telescopic fork picking components 2 arranged on the mounting base 1 along the length direction of the mounting base 1. The telescopic fork picking component 2 itself can generate telescopic movement so that its overall length becomes longer or shorter. The telescopic direction of the telescopic fork picking component 2 is perpendicular to the arrangement direction of the telescopic fork picking component 2. When the middle two telescopic fork picking components 2 need to be used, the lengths of the telescopic fork picking components 2 on both sides are shortened while the lengths of the middle two telescopic fork picking components 2 become longer, enabling the telescopic fork picking component 2 to extend or shorten according to the specifications of the pallet, and realizing the picking of pallets of different specifications.

[0045] The telescopic fork picking component 2 includes a base 21 installed on the mounting base 1, a fork arm 22 slidably arranged on the base 21, and a driving member 23 for driving the fork arm 22 to move. The bases 21 are all arranged on the mounting base 1 and arranged along the length direction of the mounting base 1. The fork arm 22 includes a main fork 221 slidably arranged on the base 21, a middle fork 222 slidably arranged on the main fork 221, and a small fork 223 slidably arranged on the middle fork 222. The main fork 221, the middle fork 222, and the small fork 223 are slidably matched through guide rails in sequence. The main fork 221, the middle fork 222, and the small fork 223 move in one direction so that the overall length of the telescopic fork picking component 2 becomes longer, realizing the picking of the pallet.

[0046] As Figure 2 and Figure 3As shown in the figure, the driving member 23 includes a gear 231 rotatably connected to the base 21, a rack 232 mounted below the main fork 221, two chains 233 for driving the small fork 223 to move, a plurality of sprockets 234 for guiding the two chains 233 respectively, and a motor 235 for driving the gear 231 to move. The rack 232 is arranged along the length direction of the main fork 221. Two gears 231 are provided and meshed with each other. The upper gear 231 meshes with the rack 232, so as to drive the main fork 221 to move when the gear 231 rotates. The sprockets 234 are arranged at both ends of the main fork 221 and both ends of the middle fork 222. The chains 233 are arranged around the two sprockets 234 on the main fork 221 and the two sprockets 234 on the middle fork 222. Both ends of the chain 233 arranged on the main fork 221 are fixed, and the chain 233 is simultaneously fixed to one end of the upper end surface of the base 21 close to the extending direction of the main fork 221 and one end of the middle fork 222 close to the retracting direction. Both ends of the chain 233 arranged on the middle fork 222 are fixed, and the chain 233 is simultaneously fixed to one end of the main fork 221 close to the extending direction and one end of the small fork 223 close to the retracting direction. When the gear 231 drives the main fork 221 to extend, it can drive the chain 233 to rotate, so that the middle fork 222 and the small fork 223 both extend.

[0047] The motors 235 of the two intermediate telescopic fork picking components 2 are respectively mounted below the adjacent bases 21, and the motors 235 of the two telescopic fork picking components 2 on both sides are respectively mounted below the adjacent bases 21, thus leaving a space for mounting the motor 235.

[0048] As Figure 2 shown in the figure, since the base 21 will produce a certain downward deformation due to the force during work, when the motor 235 transmits power to the gear 231, a relative displacement will occur between the motor 235 and the gear 231, affecting the driving of the gear 231 by the motor 235. Therefore, the motor 235 is connected to the gear 231 through a transmission component 3. The transmission component 3 includes a rotating shaft 31 rotatably connected to the lower part of the base 21 and spherical hinge joints 32 respectively arranged at the two ends of the rotating shaft 31. The spherical hinge joints 32 are coaxially arranged with the rotating shaft 31. The spherical hinge joint 32 at one end is connected to the gear 231, and the spherical hinge joint 32 at the other end is connected to the output shaft of the motor 235 through a retracting component 4. The spherical hinge joint 32 is used to realize the transmission of power between the motor 235 and the gear 231, and when the relative position between the motor 235 and the gear 231 changes, the motor 235 can also normally drive the gear 231 to rotate.

[0049] As Figure 2 and Figure 4As shown, the retraction assembly 4 includes a retraction rod 44 coaxially mounted on the output shaft of the motor 235, a retraction sleeve 41 mounted on the spherical hinge 32 near one end of the motor 235, a plurality of rolling balls 42 disposed in the retraction sleeve 41, and a plurality of elastic members 43 for pushing the rolling balls 42 to move towards the retraction rod 44. The retraction sleeve 41 is sleeved on the retraction rod 44. A plurality of sliding grooves 411 penetrate through the inner wall of the retraction sleeve 41 in the circumferential direction. The rolling balls 42 and the elastic members 43 are both disposed in the sliding grooves 411. A plug for closing the opening of the sliding groove 411 is threadedly connected to one end of the sliding groove 411 away from the axis of the retraction sleeve 41. The elastic member 43 is selected as a spring in this embodiment. One end of the elastic member 43 abuts against one end of the rolling ball 42 away from the retraction rod 44, and the other end of the elastic member 43 abuts against the plug, so that the elastic member 43 can be used to push the rolling ball 42 to always abut against the retraction rod 44. A plurality of retraction grooves 441 are circumferentially formed on the surface of the retraction rod 44. The depth of the retraction grooves 441 is less than the radius of the rolling ball 42. The rolling balls 42 are embedded in the retraction grooves 441. Thus, when the retraction rod 44 rotates, the rolling balls 42 and the retraction sleeve 41 can be driven to rotate by relying on the friction force between the rolling balls 42 and the retraction rod 44. When the force on the fork arm 22 towards the base 21 changes and causes the fork arm 22 to retract, the rolling balls 42 are pressed and all retract from the retraction grooves 441, causing relative rotation between the retraction sleeve 41 and the retraction rod 44, enabling the fork arm 22 to retract and the motor 235 to be not easily damaged.

[0050] In order to prevent the retraction rod 44 from disengaging from the retraction grooves 441 during normal operation, two bearing seats 24 are further installed at the lower end of the base 21. The retraction rod 44 and the retraction sleeve 41 are both mounted on the bearing seats 24 through bearings, and the relative positions of the retraction rod 44 and the retraction sleeve 41 are limited by the bearing seats 24, so that the two can be stably connected.

[0051] The implementation principle of this embodiment is as follows: When it is necessary to fork a pallet, select the two middle telescopic fork components 2 or the telescopic fork components 2 on both sides according to the size of the pallet. After the selection is completed, the motor 235 rotates to drive the main fork 221 to extend. At the same time, the chain 233 also drives the middle fork 222 and the small fork 223 to extend. After the small fork 223 and the main fork 221 are all extended, the middle fork 222 and the small fork 223 extend under the pallet to fork the pallet.

[0052] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
