[0002] Nowadays, industrial robots are widely used in various production and manufacturing fields. However, except for some collaborative robots with high safety performance that can be set beside personnel to work together, most industrial robots need to build guardrails for isolation in their working places to meet the conditions for safe operation.

[0003] In most of the existing guardrails, the wire mesh and the columns are mostly connected by welding. However, this method is not convenient for the flexible disassembly and assembly of the wire mesh and the columns. There are also some existing technologies that weld the wire mesh in a support frame and then connect the support frame to the columns through bolts. Although this method can achieve the flexible disassembly and assembly between the wire mesh and the columns, the wire mesh is restricted within the support frame and cannot be flexibly cut according to the on-site requirements, resulting in poor adaptability.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an industrial robot guardrail.

An extension part and a bending part are provided on the side of the connecting plate away from the wire mesh. The extension part is fixedly connected to the column through a second bolt. A limiting groove is provided on the column, and the bending part is snapped into the limiting groove.

[0007] In one of the embodiments, the limiting protrusion is a frustum structure with an area gradually shrinking from the mating plate towards the connecting plate, and the maximum area of the limiting protrusion is larger than the area of the grid.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1 to 4 shown, an embodiment of the present application provides an industrial robot guardrail, which includes a plurality of guardrail bodies. The plurality of guardrail bodies are sequentially connected and surrounded to form the guardrail. The guardrail body includes a column 2, a wire mesh 1, and a detachable connection structure for connecting and fixing the wire mesh 1 to the column 2. The wire mesh 1 includes a plurality of grids 12 formed by welding a plurality of wires 11 vertically and horizontally. The detachable connection structure includes a connecting plate 5 and a mating plate 8. A first bolt 6 for clamping and fixing the wire mesh 1 is connected between the connecting plate 5 and the mating plate 8. A limiting protrusion 81 that can extend into the grid 12 is provided on the mating plate 8. An extension part 52 and a bending part 53 are provided on the side of the connecting plate 5 away from the wire mesh 1. The extension part 52 is fixedly connected to the column 2 through a second bolt 7. Bolt holes for the second bolt 7 to penetrate are provided on the extension part 52 and the column 2. A limiting card slot 22 is provided on the column 2. The bending part 53 is snapped into the limiting card slot 22.

[0020] The implementation principle of the above industrial robot guardrail is as follows: During installation, first fix a plurality of columns 2 at predetermined positions to form the basic framework of the guardrail, and then use the detachable connection structure to sequentially install the wire mesh 1 between the columns 2. The specific operation is as follows: Align the limiting protrusion 81 on the mating plate 8 with the grid 12 of the wire mesh 1 and insert it, and then clamp and fix the wire mesh 1 by the connecting plate 5 and the mating plate 8 through the first bolt 6; then align the extension part 52 on the connecting plate 5 with the bolt hole on the column 2, and at the same time snap the bending part 53 on the connecting plate 5 into the limiting card slot 22 of the column 2, and tighten and connect through the second bolt 7 to complete the entire installation process.

[0021] When it is necessary to disassemble or replace the wire mesh 1, just reverse the above steps.

[0022] In the above manner, the installation and disassembly process is simplified and the work efficiency is improved by setting the detachable connection structure. At the same time, it is also convenient to maintain or replace parts when necessary. At the same time, the detachable connection structure and the column 2 and the wire mesh 1 are all detachable. Since the wire mesh 1 is not fixedly welded in the support frame, but is connected to the column 2 through the detachable connection structure, the user can flexibly cut the size of the wire mesh 1 according to the specific needs of the site to adapt to work areas of different sizes or shapes, thereby enhancing the adaptability and flexibility of the guardrail and enabling it to be more widely used in various industrial environments. At the same time, the limiting protrusion 81 set on the adapter plate 8 can extend into the frame 12 of the wire mesh 1, effectively preventing the wire mesh 1 from being displaced or falling off when subjected to external force, thereby ensuring the stability and safety of the guardrail, and the bending portion 53 on the connecting plate 5 is snapped into the limiting slot 22 on the column 2, further enhancing the stability of the connection structure and preventing safety hazards caused by loose connection.

[0023] In this embodiment, the limiting protrusion 81 is a prism structure with an area that shrinks from the adapter plate 8 toward the connecting plate 5 , and the maximum area of ​​the limiting protrusion 81 is greater than the area of ​​the frame 12 .

[0024] In the above manner, when the limiting protrusion 81 of the prism structure is inserted into the frame 12 of the wire mesh 1, since its maximum area is larger than the area of ​​the frame 12, it can provide a larger contact area and a tighter fit, so that the wire mesh 1 is not easy to fall out of the limiting protrusion 81 when subjected to external force, thereby enhancing the stability of the entire guardrail.

[0025] In this embodiment, the connecting plate 5 is provided with a connecting hole 51, the adapter plate 8 is provided with a threaded hole 82 at a position opposite to the connecting hole 51 and penetrating the limiting protrusion 81, and the bolt includes a rotating portion and a threaded portion, the rotating portion is rotatably connected to the connecting hole 51, and the threaded portion is threadedly connected to the threaded hole 82. Through the connection of the rotating portion and the threaded portion of the bolt with the connecting hole 51 and the threaded hole 82 respectively, more precise assembly positioning can be achieved, the rotation of the rotating portion in the connecting hole 51 can ensure that the bolt is aligned and smoothly enters the threaded hole 82 during the installation process, and the close fit between the threaded portion and the threaded hole 82 ensures the stability and reliability of the connection.

[0026] In this embodiment, a plurality of reinforcing structures are provided on the steel wire mesh 1 , and the reinforcing structures include an arc-shaped portion 111 formed by bending the steel wires 11 in the longitudinal position and the steel wires 11 in the transverse position connected to the arc-shaped portion 111 .

[0027] In the above method, the arrangement of the arc portion 111 can disperse and resist forces from different directions, while the transverse steel wires 11 connect these arc portions 111 to form a more stable structure, making the wire mesh 1 not easily deformed or broken when subjected to external force impacts, thereby improving its durability and safety.

[0028] In this embodiment, a doorway 3 is formed at intervals between any two adjacent guardrail bodies. A sliding door 4 for opening and closing the doorway 3 is provided on the guardrail body. The sliding door 4 adopts the prior art, and its detailed structure will not be elaborated in this embodiment. The arrangement of the sliding door 4 enables personnel or materials to conveniently enter and exit the area enclosed by the guardrail when needed. Compared with traditional fixed doors or swing doors, the sliding door 4 is faster and smoother when opening and closing, reducing waiting time and traffic obstacles, and improving work efficiency.

[0029] In this embodiment, a base 21 is fixedly connected to the bottom of the column 2, and the base 21 is fixedly connected to the ground through expansion bolts.

[0030] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
