Description

Technical Field

[0001] The utility model belongs to the technical field of stackers, and particularly relates to a cargo fixing device for a stacker. Background Art

[0002] A stacker is a key device in a modern logistics warehousing system. In an automated stereoscopic warehouse, the stacker can perform the operations of storing and retrieving goods, and place the goods at a designated position or retrieve the goods from a designated position through a lifting and traveling mechanism. The use of the stacker greatly reduces the labor demand and improves the efficiency of warehouse handling. However, the existing stackers cannot effectively fix goods of different shapes and sizes during operation, resulting in unstable fixation of the goods on the stacker. During transportation, the goods are prone to move, tilt, or even slide, causing economic losses and posing safety risks. Summary of the Utility Model

[0003] In view of this, to solve the above technical problems, the utility model provides a cargo fixing device for a stacker, which can effectively fix goods of different sizes on the stacker and effectively improve the stability of transporting goods by the stacker.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0005] A cargo fixing device for a stacker, characterized by comprising:

[0006] An installation base plate;

[0007] A height adjustment component, the height adjustment component includes an electric slide rail group vertically arranged on the installation base plate, a horizontal cantilever with one end connected to the electric slide rail group and capable of sliding in the vertical direction, and a mounting seat connected to the other end of the horizontal cantilever;

[0008] A clamping component, the clamping component includes a double-rod hydraulic cylinder, clamping arms, and a limiting mechanism; the double-rod hydraulic cylinder is installed in the mounting seat, and the telescopic directions of its two telescopic rods are left and right; there are two clamping arms, and the upper ends of the two clamping arms are respectively connected to the free ends of the two telescopic rods; there are two limiting mechanisms, symmetrically installed at the lower ends of the two clamping arms, and the two limiting mechanisms are used to clamp the goods symmetrically left and right;

[0009] A pressing component, the pressing component is arranged on the lower end surface of the mounting seat and is used to press against the goods from the top.

[0010] This fixing device is fixed to the load-carrying plate of the stacker through the mounting base plate. The mounting base plate can be connected to the load-carrying plate by welding or bolt fixing, and it can move up and down with the load-carrying plate. The height adjustment component can adjust the height of the horizontal cantilever, thereby adjusting the heights of the clamping component and the pressing component. For goods of different sizes, the horizontal cantilever is adjusted to an appropriate position so that the pressing component presses against the top of the goods, forming a clamping force between the load-carrying plate of the stacker. The clamping component adjusts the left and right sides through the two telescopic rods of the double-rod hydraulic cylinder, so that the two symmetrical limiting mechanisms on the left and right press against the left and right sides of the goods, forming a clamping force.

[0011] Furthermore, the mounting base plate is a rectangular plate-like structure, and its upper end surface can be fixed to the lower end surface of the load-carrying plate of the stacker by welding or bolt fixing.

[0012] The mounting base plate is connected from the rear side of the load-carrying plate. This fixing device is located at the rear side of the load-carrying plate, which does not affect the connection between the load-carrying plate and the lifting devices on the left and right sides of the stacker frame, nor does it affect the loading and unloading in the front side of the load-carrying plate.

[0013] Furthermore, the electric slide rail group includes a vertically upward housing fixed to the upper end surface of the mounting base plate, a rotary drive motor installed at the bottom of the inner cavity of the housing, a lead screw vertically arranged in the inner cavity of the housing driven by the rotary drive motor, a sliding connection seat fixed to the lead screw nut on the lead screw, and a moving plate connected to the sliding connection seat; a vertical slideway is provided on the front side wall of the housing, and the moving plate is located on the outer side surface of the front side wall of the housing and can move along the slideway; one end of the horizontal cantilever is fixed to the moving plate.

[0014] The rotary drive motor drives the lead screw to rotate. The lead screw nut drives the sliding connection seat to move up and down along the lead screw, and then the moving plate moves along the slideway, finally realizing the height adjustment of the horizontal cantilever.

[0015] Furthermore, the limiting mechanism includes a limiting plate, a clamping soft pad installed on the clamping surface of the limiting plate, a shaft rod fixed to the back surface of the limiting plate at one end, and a spring fixed to the back surface of the limiting plate at one end; the other end of the shaft rod is movably connected to the inner side surface of the lower end of the clamping arm through a rotating shaft; the other end of the spring is fixed to the inner side surface of the lower end of the clamping arm.

[0016] The limiting plate and the clamping arm are connected by a shaft rod and a rotating shaft, which can make the limiting plate rotate within a certain range. At the same time, a spring is set to limit the limiting plate, so that it can better fit and press against goods with different shapes, with stronger adaptability and better stability; the clamping soft pad can be a silica gel soft pad, which can avoid scratching the surface of the goods, and at the same time increase the friction force of the contact surface and clamp more firmly.

[0017] Further, a stabilizing plate parallel to the limiting plate is further provided at the lower end of the clamping arm; the stabilizing plate and the limiting plate are connected by a spring.

[0018] Further, the pressing assembly includes a fixing base installed on the lower end surface of the mounting base, a pressing plate fixed to the lower end surface of the fixing base, and a pressing soft pad installed on the lower end surface of the pressing plate.

[0019] The pressing soft pad can be a silica gel soft pad, which can avoid scratching the surface of the goods, improve the friction of the contact surface at the same time, and make the clamping more stable.

[0020] Compared with the prior art, the goods fixing device for a stacker of the present utility model has the following advantages:

[0021] (1) The goods fixing device for a stacker of the present utility model is convenient to install, can be directly fixed on the loading plate of the stacker, and does not affect the operation of the stacker itself; through the height adjustment assembly, the clamping assembly, and the pressing assembly, different sizes of goods carried can be effectively fixed in multiple directions, preventing the goods from moving and sliding during loading and unloading, and improving the stability and safety of the stacker in carrying goods.

[0022] (2) The limiting plate and the clamping arm of the goods fixing device for a stacker of the present utility model are connected by a shaft rod and a rotating shaft, so that the limiting plate can rotate within a certain range, and at the same time, a spring is provided to limit the limiting plate, which can better fit and resist goods with different shapes, with stronger adaptability and better stability.
