Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, and in particular to a protective device for multiple-length flying shears. Background Technology

[0002] Multiple-length flying shears are key pieces of equipment on steel rolling production lines, primarily used to cut rolled steel to a predetermined length. During operation, the internal shearing mechanism operates at high speed, posing a safety hazard and potentially causing accidental injury to operators. Therefore, to ensure production safety, protective devices must be installed on multiple-length flying shears. Existing multiple-length flying shear protective devices are typically fixed structures with a fixed protection range, making it difficult to flexibly adjust to the shearing requirements of different steel specifications in actual production, resulting in less than ideal protective effects. Furthermore, the installation and disassembly of some protective devices are cumbersome, hindering subsequent maintenance and repair. Therefore, we propose a multiple-length flying shear protective device to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a protective device for multiple-length flying shears, which can flexibly adjust the protection range according to actual production needs, thereby improving the applicability and protective effect of the device. At the same time, the device is easy to install and disassemble, facilitating subsequent maintenance and repair.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a double-length flying shear protection device includes a main protective cover, a reinforcing plate fixedly installed on one side of the main protective cover, two auxiliary protective covers rotatably installed inside the main protective cover, a fixed rod fixedly installed at the bottom of the main protective cover, a rotating plate fixedly installed on the auxiliary protective cover, the rotating plate being rotatably sleeved on the fixed rod, and the two rotating plates not being on the same horizontal line; a guide groove is provided on the inner wall of the main protective cover, the two sides of the guide groove are set as openings, a guide seat is fixedly installed on the outer side of the auxiliary protective cover, and the guide seat is slidably connected to the guide groove; an adjustment mechanism is provided between the main protective cover and the auxiliary protective covers, and a fixing mechanism for fixing the main protective cover is provided on the outer side of the main protective cover.

[0005] By adopting the above technical solution, the protection range can be flexibly adjusted according to actual production needs, which improves the applicability and protection effect of the protective device; at the same time, the protective device is easy to install and disassemble, which facilitates later maintenance and repair work.

[0006] The present invention is further configured such that: the adjustment mechanism includes an arc-shaped hole, a push seat and a push plate; the top of the main protective cover has two arc-shaped holes; the top of the secondary protective cover is fixedly installed with a push seat; the push seat passes through the arc-shaped holes and is fixedly installed with a push plate; when the push plate is pushed, the push plate drives the secondary protective cover to rotate through the push seat; the arc-shaped holes provide a path for the movement of the push seat. By adopting the above technical solution, the rotation adjustment of the secondary protective cover can be achieved through a simple pushing action, providing a convenient operation method for changing the protection range. A further feature of this invention is that the top of the main protective cover has multiple slots, and a mating mechanism is provided between the push plate and the corresponding slot. The mating mechanism can fix the push plate in the corresponding position, thereby fixing the secondary protective cover. The mating mechanism includes a moving hole and a plug rod. The push plate has a moving hole, and the plug rod is slidably installed in the moving hole. The plug rod is adapted to the corresponding slot, and the push plate can be fixed by inserting the plug rod into the slot.

[0007] By adopting the above technical solution, the adjusted push plate can be firmly fixed, thereby ensuring that the secondary protective cover works stably in the set position and preventing it from moving accidentally and affecting the protective effect. A further feature of this invention is that the top ends of the two corresponding insertion rods are fixedly equipped with the same handle, and the handle is located above the push plate. The handle facilitates the operator's operation of the insertion rods and ensures that the two insertion rods move synchronously.

[0008] By adopting the above technical solution, it is easier for operators to operate the two insertion rods at the same time, thus improving the convenience and synchronization of the insertion mechanism operation. A further feature of this invention is that the bottom of the push plate has two spring grooves, and a clamping mechanism for pressing the insertion rod is provided in the spring grooves. The clamping mechanism includes a baffle and a compression spring. The baffle is fixedly sleeved on the insertion rod, the bottom end of the compression spring is fixedly installed on the baffle, and the top end of the compression spring is fixedly installed on the top inner wall of the spring groove. When the compression spring is in a compressed state, its elastic force acts on the insertion rod through the baffle, causing the insertion rod to have a downward tendency, thereby ensuring that the insertion rod can be tightly inserted into the slot.

[0009] By adopting the above technical solution, the elastic force of the compression spring is used to continuously apply downward pressure to the insertion rod, ensuring that the insertion rod and the slot are always tightly fitted, thus enhancing the reliability of the fixation. The present invention is further configured such that: the fixing mechanism includes a mounting base, a threaded hole and a fixing bolt; multiple mounting bases are fixedly installed at equal intervals on the outer side of the main protective cover; the top of the mounting base is provided with a threaded hole; a fixing bolt for fixing the main protective cover is installed in the threaded hole; the mounting base is connected to the double-length flying shear by the fixing bolt, thereby realizing the fixed installation of the main protective cover.

[0010] By adopting the above technical solution, the main protective cover can be firmly installed on the double-length flying shear, and the threaded connection makes the installation and disassembly process simple and easy, facilitating equipment maintenance. A further feature of this invention is that a rotating hole is provided on the rotating plate, and the rotating hole is rotatably connected to the fixed rod. The rotating hole provides conditions for the rotating plate to rotate around the fixed rod. The number of the multiple slots located on the same side is set to six to ten, and the six to ten slots are equally spaced. The multiple equally spaced slots can provide multiple fixed positions for the secondary protective cover to meet different protection requirements.

[0011] By adopting the above technical solution, the smoothness of the rotating plate is ensured, and multiple fixing options are provided for the secondary protective cover, which can better adapt to the protection needs of steel of different specifications.

[0012] The beneficial effects of this utility model are: (1) By setting up a main protective cover and two auxiliary protective covers, the multiple-length flying shear can be protected in all directions, effectively blocking the debris and foreign matter that may be splashed out during the shearing process, and ensuring the safety of the operators. The setting of the reinforcing plate enhances the structural strength of the main protective cover and improves the stability and durability of the entire protective device. (2) The opening and closing angles of the two auxiliary protective covers can be easily adjusted using the adjustment mechanism, thereby flexibly changing the protection range according to the shearing requirements of steel of different specifications. When adjustment is required, the push plate is pushed, which drives the push seat to move along the arc-shaped hole, thereby causing the auxiliary protective cover to rotate around the fixed rod. During the rotation of the auxiliary protective cover, the guide seat slides in the guide groove, providing a stable guiding effect for the rotation of the auxiliary protective cover and ensuring that its rotation process is smooth and reliable.
