Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment protection technology, and in particular to a protective device for the roller chain of a quenching machine. Background Technology

[0002] In the production of medium and heavy plates, the quenching machine roller conveyor is typically driven by a motor via a chain and sprocket system. During equipment operation, the chains, sprockets, and other components rotate at high speed. The existing technology suffers from the following prominent problems: First, there are significant safety hazards. The rotating parts of the quenching machine, such as the roller chain and sprockets, are usually exposed. During operation, the clothing and tools of operators and inspectors are easily caught in these rotating parts, or even come into direct contact with the body, causing serious mechanical injuries. Furthermore, the chain may break at high speeds, and flying debris can cause injury to nearby personnel.

[0003] Secondly, maintenance is time-consuming. The roller chains of quenching machines are prone to damage due to long-term high-speed operation and require regular replacement. Currently, most equipment uses only simple wire-bound guardrails for protection, which are not only cumbersome and time-consuming to disassemble and install, but also bulky, significantly increasing the time required to replace the chains and severely impacting the normal operating efficiency of the production line.

[0004] Therefore, there is an urgent need for a new type of protective device that can effectively isolate rotating parts, ensure personnel safety, and facilitate daily inspection and rapid maintenance. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a protective device for the roller chain of a quenching machine.

[0006] To solve the above technical problems, the technical solution of the present invention is as follows: A protective device for the roller chain of a quenching machine, comprising: The fixed frame is fixedly installed on the body of the quenching machine and is located on the outside of the roller chain of the quenching machine. A protective plate is slidably disposed within the fixed frame along the length of the fixed frame to shield the roller chain of the quenching machine.

[0007] As a preferred embodiment of the protective device for the roller chain of the quenching machine described in this invention, the fixed frame includes an upper crossbeam and a lower crossbeam that are parallel to each other and spaced apart. Both the upper crossbeam and the lower crossbeam are fixedly installed on the quenching machine body, and the protective plate is slidably installed between the upper crossbeam and the lower crossbeam.

[0008] As a preferred embodiment of the protective device for the roller chain of the quenching machine described in this invention, the upper crossbeam and the lower crossbeam are both I-beams, and the open side of the upper crossbeam and the open side of the lower crossbeam are arranged opposite to each other. The upper and lower ends of the protective plate are slidably disposed in the grooves of the upper and lower crossbeams, respectively.

[0009] As a preferred embodiment of the protective device for the roller chain of the quenching machine according to the present invention, wherein: a plurality of protective plates are provided, and the plurality of protective plates are arranged sequentially along the length direction of the fixed frame; The thickness of the protective plate is less than half the width of the groove.

[0010] As a preferred embodiment of the protective device for the roller chain of the quenching machine described in this invention, the fixed frame further includes reinforcing ribs for increasing load-bearing capacity. The reinforcing ribs are fixedly installed on the lower surface of the upper crossbeam and / or the lower surface of the lower crossbeam, and are fixedly connected to the quenching machine body.

[0011] As a preferred embodiment of the protective device for the roller chain of the quenching machine described in this invention, the reinforcing rib plate has a triangular structure.

[0012] As a preferred embodiment of the protective device for the roller chain of the quenching machine described in this invention, the protective plate is a protective grid.

[0013] The beneficial effects of this invention are: (1) By setting up a fixed frame and protective plate, the present invention completely physically isolates all rotating parts such as chains and sprockets of the quenching machine roller conveyor, effectively eliminating the risk of accidental contact by personnel. At the same time, it can block parts that are splashed due to chain breakage, greatly reducing the probability of mechanical injury and object impact accidents.

[0014] (2) The protective plate of the present invention adopts a push-pull structure design. When the chain needs to be inspected, replaced or repaired, the protective area can be opened or closed simply by pushing and pulling the protective plate. Unlike the traditional wire-binding guardrail, there is no need for cumbersome disassembly and reinstallation, which greatly shortens the maintenance operation time and improves the effective operation rate of the equipment and the production line capacity.

[0015] (3) This invention mainly uses common materials such as I-beams, steel plates, and standard mesh guardrails. It can be manufactured through conventional processes such as welding and cutting. It has a simple structure, is sturdy and durable, and can adapt to the harsh working environment of high temperature, high humidity and dust around the quenching machine. It also has low manufacturing cost and long service life. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a schematic diagram of the protective device for the roller chain of a quenching machine provided by the present invention; Figure 2 This is a schematic diagram of another working state of the protective device for the roller chain of a quenching machine provided by the present invention. The components include: 1. Fixed frame; 2. Upper crossbeam; 3. Lower crossbeam; 4. Protective panel. Detailed Implementation

[0018] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] Figure 1 This is a schematic diagram of a protective device for the roller conveyor chain of a quenching machine provided in an embodiment of this application. The device mainly includes a fixed frame 1 and a protective plate 4. The fixed frame 1 and the protective plate 4 completely physically isolate all rotating parts of the quenching machine roller conveyor, such as the chain and sprockets.

[0020] Specifically, the fixed frame 1 provides overall support and is fixedly connected to the quenching machine body. In this embodiment, the fixed frame 1 includes an upper crossbeam 2 and a lower crossbeam 3 that are parallel to each other and spaced apart. Both the upper crossbeam 2 and the lower crossbeam 3 are made of 18# I-beams, and their lengths are determined according to the protection range of the quenching machine roller chain, for example, 4800mm. The upper crossbeam 2 and the lower crossbeam 3 are fixedly installed on the original frame columns of the quenching machine by welding (preferably full welding), wherein the lower crossbeam 3 is welded to the base, and the height of the upper crossbeam 2 from the lower crossbeam 3 can be, for example, 1900mm.

[0021] To further enhance the load-bearing capacity of the fixed frame 1, the fixed frame 1 also includes a reinforcing rib plate for increasing the load-bearing capacity. The reinforcing rib plate is fixedly installed on the lower surface of the upper crossbeam 2 and / or the lower surface of the lower crossbeam 3, and is fixedly connected to the quenching machine body.

[0022] In this embodiment, the stiffening plate is a triangular structure cut diagonally from a 300mm×300mm steel plate, and a total of four pieces are provided, which are respectively welded to the lower surface of the upper crossbeam 2 and the lower crossbeam 3.

[0023] The protective plate 4 adopts a grid-like structure with a grid size of 30mm × 30mm to ensure protective effect while facilitating observation of the internal chain operation. In this embodiment, three protective plates 4 are provided. The upper and lower edges of the protective plate 4 are respectively inserted into the grooves of the I-beams that serve as the upper crossbeam 2 and the lower crossbeam 3, thereby allowing it to slide freely along its length within the fixed frame 1.

[0024] It should be noted that the thickness of the protective plate 4 is less than half the width of the groove. This allows adjacent protective plates 4 to intersect. (See also...) Figure 1 Under normal operating conditions, the protective plate 4 is pushed or pulled to interlock, covering the entire chain drive area and forming a complete physical barrier, effectively preventing personnel or objects from contacting the rotating chain and sprockets. (See also...) Figure 2 When the chain needs to be inspected, maintained, or replaced, the operator only needs to push or pull the protective plate 4 along the length of the fixed frame 1, i.e., along the direction of the groove, to open one or more operating windows for convenient operation. After the operation is completed, the protective plate 4 can be pushed back to its original position.

[0025] Therefore, the technical solution of this application, by setting up a fixed frame 1 and a protective plate 4, completely physically isolates all rotating parts of the quenching machine roller conveyor, such as chains and sprockets, effectively eliminating the risk of accidental contact by personnel. At the same time, it can block parts that fly out due to chain breakage, greatly reducing the probability of mechanical injury and object impact accidents. In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
