[0031] like Figure 1-10 As shown, one specific embodiment of an anti-callback brick clamp is shown, wherein the hydraulic pipelines of the grabbing and releasing cylinder, the adjusting cylinder and the hydraulically controlled motor are not shown in the figure, and the air pipeline of the telescopic cylinder is also not shown. The control methods thereof are all existing technologies and will not be described in detail here. Specifically, it includes a fixing device 1, which includes a bottom fixing part 101, an intermediate support frame 102 and an upper connecting plate 103. The connecting plate is welded to the upper end of the support frame and the fixing part is welded to the lower end to form a fixing device. The top of the fixing device 1 is rotatably connected to the rotating gear 6, and the rotating gear is fixedly installed with a fixing block. The specific method adopted in this embodiment is that the rotating gear 6 is connected to the connecting plate 103 through a rotating disk 11. The upper end surface of the rotating gear 6 is provided with an annular inner groove 12, and the upper end surface of the rotating disk 11 is provided with an annular flange 13; the flange 13 is embedded in the inner groove 12, and the lower end surface of the rotating disk 11 is bolted to the connecting plate 103 below through the inner ring of the rotating gear 6. All devices below the connecting plate are now integrated with the rotating disk 11, which is suspended from the rotating gear 6 and can rotate relative to it. A hole is provided in the connecting plate 103 for the hydraulic motor 8 to pass through. The hydraulic motor is bolted to the support frame 102 of the fixed device 1, and its rotating shaft passes through the hole in the connecting plate 103. A power gear 9 is mounted on the rotating shaft of the hydraulic motor 8, which meshes with the rotating gear 6. The interaction between the power gear 9 and the rotating gear 6 drives the fixed device 1 and other devices connected thereto to rotate.

[0032] like Figure 2-5 There are two fixing members 101, one welded to the front and rear sides of the fixture. Each fixing member 101 comprises two opposing fixing plates 1011 and a cover plate 1012 fixedly connected to the upper and lower ends of the two fixing plates 1011, creating a cavity within the fixing member. Both ends of the fixing plates 1011 are provided with waist-shaped holes 104. The waist-shaped holes at the ends of the two fixing plates on the same fixing member are arranged in a facing relationship, and the length of the waist-shaped holes 104 is horizontal.

[0033] A movable wall 3 is installed on both sides of the fixing device. The movable wall 3 includes two support plates 301 and a wall plate 302 welded to the lower ends of the two support plates 301. The wall plate is used to clamp the brick stack. A reinforcement plate 303 is welded between the upper ends of the two support plates 301 on the same side. In this specific embodiment, the reinforcement plate and the support plate are formed as an integral plate, which increases the connection strength between the two support plates. The two support plates 301 are matched with two fixing members 101 respectively, and the support plates are located between the two fixing plates 1011 of the corresponding fixing members. A hinge shaft 2 is installed between the two opposite waist-shaped holes 104 on the same side of the fixing member. The hinge shaft can move along the length of the waist-shaped hole. Both hinge shafts 2 are rotatably connected to the support plates 301. Specifically, the support plates are welded with sliding sleeves, which are mounted on the hinge shafts, allowing the support plates to rotate around the hinge shafts, thereby allowing the entire movable wall to rotate around the hinge shafts to clamp or release the brick stack and achieve displacement of the brick stack. A grab-and-release cylinder 4 is installed between the upper ends of the two movable walls 3. There are two grab-and-release cylinders 4, one on each side of the movable wall 3, to balance the applied force. The specific connection method is to weld a hinge plate to the movable wall, and both ends of the grab-and-release cylinder 4 are hinged to the hinge plate via a pin. Two adjustment cylinders 5 are installed in each fixed component 101. The fixed ends of the two adjustment cylinders are installed in the middle of the fixed component, and the telescopic ends of the two adjustment cylinders can be extended to the sides of the fixed component. The telescopic ends of the adjustment cylinders are connected to the hinge shaft via earrings and are used to adjust the position of the hinge shaft 2 on both sides within the waist-shaped hole 104. When the two adjustment cylinders 5 are extended, the hinge shaft can move toward the sides along the waist-shaped hole, increasing the distance between the two movable walls to accommodate wider brick stacks. When the two adjustment cylinders 5 are shortened, the hinge shaft can move toward the inside of the waist-shaped hole to reduce the distance between the two movable walls to accommodate narrower brick stacks.

[0034] like Figure 2-7As shown, in this specific embodiment, a positioning device 15 is installed between both sides of the two fixed members. The positioning device 15 comprises a mounting base 1501, two telescopic cylinders 1502 fixed to the mounting base 1501, and a stopper 1503 welded to the telescopic ends of the telescopic cylinders 1502. Specifically, the positioning device is installed between the two fixed members via the mounting base, with one positioning device installed at each end of the two fixed members. The control principle and control device of the telescopic cylinders are not further described here. The stopper 1503 is an elongated strip with an arc-shaped groove 1504 at one end. When the articulated shaft 2, driven by the adjustment cylinder, reaches the inward end of the waist-shaped hole 104, the stopper 1503 is able to enter the waist-shaped hole 104. The groove 1504 matches the outer contour of the articulated shaft 2, and the end of the stopper 1503 away from the groove 1504 matches the inner contour of the waist-shaped hole 104. The stopper supports the articulated shaft, preventing the articulated shaft from moving back. Because when the movable wall is clamping the brick pile, the upper end of the grabbing and releasing oil has to extend outward to clamp the lower end of the movable wall. At this time, the hinge shaft is pushed outward. If it is fixed only by the pulling force of the oil cylinder, it will easily shift, causing the brick pile to fall. In this application, when the hinge shaft moves inward to clamp the narrow brick pile, the limit block is used to support the hinge shaft, thereby maintaining stability when clamping the brick pile. When the hinge shaft needs to be moved inward, the limit block can be retracted from the waist-shaped hole by the telescopic cylinder. In addition, a slide rail 17 is fixed between the two sides of the two fixing members 101, and a slider 18 is fixed to the telescopic end of the two telescopic cylinders 1502 on the positioning device 15. The slider 18 cooperates with the slide rail 17. When the telescopic cylinder is extended or shortened, the movement of the limit block is guided by the slide rail, and the movement trajectory is more stable to prevent vibration, so that the limit block can accurately enter the waist-shaped hole.

[0035] like Figure 1 、 2 As shown, in addition to the above features, in this embodiment, a synchronization device 10 is also provided between the two movable walls 3. The synchronization device 10 includes two connecting arms 1001, two fixed arms 1002 and two synchronization gears 1003. The synchronization gears 1003 are rotatably provided on the fixed device 1, and the two synchronization gears 1003 are engaged with each other. The two synchronization gears 1003 are respectively welded to one end of the fixed arm 1002, and the other end of the fixed arm 1002 is hinged to one end of the connecting arm 1001, and the other end of the connecting arm 1001 is hinged to the movable wall 3. When the grabbing and releasing cylinder 4 is extended, the rotation angles of the movable 3 on both sides are the same, and the brick clamping will not be deflected. The synchronization device is also divided into two groups, and one grabbing and releasing cylinder 4 corresponds to one group of synchronization devices 10.

[0036] The fixing device 1 is provided with guard plates 16 on both sides. The lower ends of the guard plates 16 are hinged to the ends of the two fixing members 101, and the upper ends are hinged to the upper ends of the movable wall 3. The guard plates can move with the position change and movement of the movable wall, which not only protects the movable wall but also makes it more beautiful.

[0037] like Figure 11 As shown, the present invention also discloses a loader, including a telescopic arm 14, the front end of which is hinged with the above-mentioned anti-callback brick holding clamp. Specifically, the front end of the telescopic arm 14 is hinged to the fixed block 7 at the top of the anti-callback brick holding clamp. The loader can realize movement, and the telescopic arm can also be extended and retracted to a specified position, lowering the brick holding clamp, controlling the rotation of the hydraulic motor, and rotating the brick holding clamp to a specified angle. Adjusting the extension and retraction of the oil cylinder can adjust the distance between the two movable walls, so that the articulated shaft is located at the innermost and outermost states of the waist-shaped hole. When the distance between the movable walls reaches the minimum, the articulated shaft is at the innermost side of the waist-shaped hole. At this time, the control limit block enters the waist-shaped hole to prevent the articulated shaft from calling back.

[0038] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
