[0024] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0025] The present invention provides a transfer bracket for a circular workpiece. Figure 1 As shown, it includes a base 1 and three columns vertically fixedly installed on the base 1, and the three columns are correspondingly provided with a plurality of brackets arranged at intervals along their respective axes. The three correspondingly arranged brackets cooperate to form a shelf plane for the circular workpiece to be placed, wherein at least one of the three fulcrums constituting the shelf plane is a lockable movable bracket 4, so that the circular workpiece can be stably placed layer by layer in the shelf plane, thereby effectively avoiding pressure damage to the workpiece, and at the same time, the circular workpiece can be conveniently removed from the shelf plane by operating the movable bracket 4.

[0026] In the above scheme, specifically, the three columns on the bottom bracket 1 are divided into fixed columns 3 and movable columns 2 according to the bracket type thereon, wherein the bracket on the fixed column 3 is a fixed bracket 5, and the fixed bracket 5 is fixedly connected to the fixed column 3 by welding or the like; the bracket on the movable bracket 4 is a movable bracket 4, and the movable bracket 4 is rotatably sleeved on the movable column 2 in the circumferential direction, and the movable column 2 is a cylindrical structure and the movable column 2 is provided with a locking member 21 (in the embodiment, the locking member 21 is a screw) below each movable bracket 4, and the locking member 21 is arranged at intervals on the axis of the movable column 2 to realize that a plurality of movable brackets 4 are arranged at intervals on the movable column 2, each A locking mouth 411 that cooperates with the locking piece 21 to lock is provided on the lower end of each movable bracket 4. The engagement of the locking mouth 411 with the locking piece 21 can realize the positioning of the movable bracket 4 and prevent its circumferential rotation. In this way, when the movable bracket 4 is in a locked state, the three corresponding brackets arranged in the same plane can cooperate to form a resting plane for the circular workpiece to be stably placed. At the same time, each movable bracket 4 can slide upward along the movable column 2 to realize the separation and unlocking of the locking mouth 411 and the locking piece 21. After being unlocked, the movable bracket 4 can rotate circumferentially along the movable column 2 to destroy at least one resting point constituting the resting plane, so that the circular workpiece can be conveniently removed from the resting plane.

[0027] In the above scheme, it is preferred that the circular workpiece can only be removed layer by layer from top to bottom, that is, only after the upper movable bracket 4 is unlocked to remove the circular workpiece can the adjacent lower movable bracket 4 be unlocked to remove the circular workpiece; specifically, when two adjacent movable brackets 4 are in a locked state, the distance that the lower movable bracket 4 can slide upward is less than the distance required for the locking member 21 to slide out of the lock mouth 411, so that the lower movable bracket 4 cannot slide upward to unlock; when the upper movable bracket 4 is in an unlocked state, that is, the lock mouth 411 of the upper movable bracket 4 is separated from the locking member 21 and rotated to be placed on the lower locking member 21, the distance that the lower movable bracket 4 can slide upward is greater than the distance required for the locking member 21 to slide out of the lock mouth 411, so that the lower movable bracket 4 can slide upward to unlock.

[0028] In the above scheme, specifically Figure 2 , Figure 3 and Figure 4As shown, the movable bracket 4 includes a sleeve portion 41 that is sleeved and matched with the movable column 2, and a rest portion 42 fixedly connected to the sleeve portion 41, a locking opening 411 that matches with the lower locking member 21 is provided on the lower end portion of the sleeve portion 41, and a notch 412 that matches and slides with the locking member 21 is provided at the upper end portion of the sleeve portion 41 corresponding to the lower area of ​​the upper locking member 21; when two adjacent movable brackets 4 are in a locked state, the distance between the upper end portion of the lower sleeve portion 41 (the portion except the notch 412) and the lower end portion of the adjacent upper sleeve portion 41 is L1, and the distance that the locking member 21 is inserted into the locking opening 411 is L2 (i.e., the distance required for the locking member 21 to slide out of the locking opening 411), at this time L1<L2, i.e., the distance that the lower sleeve portion 41 can slide upward is not enough to support the locking opening 411 of the lower sleeve portion 41 to separate from the locking member 21 Unlock; when the upper movable bracket 4 is in an unlocked state (the lower end is placed on the locking piece 21 below after rotation) and the adjacent lower movable bracket 4 is in a locked state, the distance between the bottom of the notch 412 of the lower sleeve portion 41 and the adjacent upper locking piece 21 is L3, at this time, L3≥(L1+L2), so that the notch 412 of the lower sleeve portion 41 constitutes a yield structure of the locking piece 21, which effectively increases the distance that the lower sleeve portion 41 can slide up, and can make the lock 411 of the lower sleeve portion 41 and the corresponding locking piece 21 separated and unlocked, the upper locking piece 21 is inserted into the notch 412 of the lower sleeve portion 41 and slides along the notch 412 to realize circumferential rotation, the locking piece 21 and the notch 412 cooperate to constrain the axial rotation angle of the lower sleeve portion 41, so that the circular workpiece can be easily removed from the shelf plane.

[0029] In the above scheme, preferably, when the movable bracket 4 is in a locked state, the locking member 21 located at the top is opposite to the starting end of the slot 412, and the slot 412 cooperates with the locking member 21 to limit the maximum rotation angle of the movable bracket to 180°. In this way, after unlocking and rotating, the shelf portion 42 in the locked state at the front can be limitedly rotated to the rear, thereby avoiding collision with the shelf portion 42 during the process of picking up the round workpiece.

[0030] In the above scheme, specifically, the three columns on the base 1 are arranged in an isosceles triangle, and preferably the three columns are arranged in an isosceles triangle structure with a vertex angle less than 60°. The column corresponding to the vertex is the movable column 2, and the other two columns are fixed columns 3. In this way, by rotating and unlocking the movable bracket 4, the circular workpiece inside can be easily taken out from the two waists.

[0031] Preferably, the shelf surfaces of the three brackets constituting the shelf plane are all provided with anti-collision pads, and the anti-collision pads are sponge pads, rubber pads, etc.

[0032] Compared with the prior art, the present invention has a simple and reasonable structure. The turnover vehicle or transport vehicle can conveniently lift the transfer bracket as a whole for transportation. By embedding and locking the locking mouth of the movable bracket with the locking member below, multiple circular workpieces can be placed layer by layer on the placing plane, which can effectively avoid the circular workpieces from being subjected to force and ensure the accuracy of the circular workpieces. Furthermore, the circular workpieces placed on the transfer bracket can only be taken down layer by layer from top to bottom, which effectively ensures the orderly taking of the circular workpieces and reduces the possibility of bumps during the taking process.

[0033] The above disclosure is only an embodiment of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
