Description

Technical Field

[0001] This utility model relates to the field of industrial equipment safety protection technology, specifically a workshop corner protective fence, which is particularly suitable for the safety isolation and protection of mechanical equipment in workshops. It features a simplified structure, convenient installation, and strong resistance to deformation. Background Technology

[0002] Traditional workshop corner guardrails typically consist of framed protective netting and support poles, and their structure and installation methods have the following problems:

[0003] 1. Complex structure: Multiple main connecting pieces need to be welded to adjacent sides of the support rod, and the protective net needs to be embedded in the metal frame, making the production process cumbersome and costly;

[0004] 2. Low installation efficiency: Each piece of protective netting needs to be fixed one by one to the main and auxiliary connecting plates on both sides of the support rod with bolts. It requires two people to work together to complete the alignment of the holes and tighten the bolts, which is time-consuming and labor-intensive.

[0005] 3. Heavy and prone to rust: The framed protective net is heavy due to the presence of the metal frame, and the welded connecting pieces are prone to rusting and falling off after long-term use;

[0006] 4. Weak resistance to deformation: Traditional protective nets are prone to wavy deformation due to gravity or external forces, affecting the protective effect;

[0007] To address the aforementioned issues, there is an urgent need for a new type of corner protective fence that is structurally simplified, efficiently installed, lightweight, and durable. Summary of the Invention

[0008] This utility model aims to provide a protective fence for workshop corners. By optimizing the connection structure between the support rod and the protective net, it solves the problems of complex installation, easy corrosion, and poor deformation resistance of traditional fences, and achieves quick installation by a single person, high stability and long service life.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A protective fence for a workshop corner includes a support rod, a protective net, hook bolts, and nuts; the top of the support rod has a right-angle slot, the upper edge of the protective net is bent to form a hook, and the hook is hooked into the right-angle slot; through holes a and b are respectively opened on two adjacent sides of the support rod, and the hook bolt passes through the protective net and the through hole and is fixed by the nut.

[0011] Furthermore, this application provides a protective fence for a workshop corner, wherein the lower edge of the protective net is bent towards the front to form a stepped section, the bending angle of the stepped section is 20-40 degrees, and the length is 10-30 mm, which enhances the deformation resistance of the protective net.

[0012] Furthermore, this application provides a workshop corner protective fence, wherein the through holes a and b are staggered on two adjacent surfaces of the support rod to avoid bolt installation interference.

[0013] Furthermore, this application provides a protective fence for a workshop corner, wherein a fixing plate is welded to the bottom of the support rod, and the fixing plate is fixed to the ground by expansion bolts; multiple support rods are arranged at intervals, and a protective net covers the adjacent sides of the support rods to form a continuous protective surface.

[0014] Furthermore, this application provides a workshop corner protective fence, wherein the hook portion of the hook bolt supports the protective net upwards, and after the nut is tightened, the threaded end of the hook bolt is tightly fitted with the back of the support rod to form a bidirectional force-fixed structure.

[0015] Its core innovations are as follows:

[0016] 1. Frameless protective net design: The protective net is made of high-strength perforated metal plate or woven mesh, eliminating the metal frame and reducing the weight by more than 40%.

[0017] 2. Right-angle slot and bending structure: A right-angle slot is opened at the top of the support rod. The upper edge of the protective net is bent towards the back to form a hook part, and the lower edge is bent towards the front to form a step part. The hook part is directly hooked into the right-angle slot to achieve quick pre-fixing.

[0018] 3. Offset through hole design: Through holes a and b are opened on two adjacent sides of the support rod, and the two sets of through holes are staggered to avoid interference during bolt installation.

[0019] 4. Hook bolt connection system: Hook bolts pass through the protective net and through hole a or through hole b in sequence, and are locked to the back of the support rod by nuts to form a two-way force fixation.

[0020] 5. Corrosion-resistant design: The welded connecting plate structure is completely abandoned, and bolts are used for direct connection to avoid failure caused by corrosion of the welded parts.

[0021] This invention has the following advantages over the prior art:

[0022] 1. Single-person installation: The protective net is pre-fixed by right-angle slots, eliminating the need for lifting and hole alignment. Installation can be completed by a single person, reducing time by more than 50%.

[0023] 2. Reduced manufacturing costs: Eliminating the frame and connecting pieces reduces material costs by 30% and simplifies the production process.

[0024] 3. Lightweight and deformation resistant: The frameless design reduces weight, the bending structure improves bending strength, and the flatness retention rate of the protective netting is increased by 60%.

[0025] 4. Rust resistance and long service life: There are no welded connecting pieces; the bolts are used for direct connection, which extends the service life by more than 2 times.

[0026] 5. Flexible adaptation: The right-angle slot and staggered through-hole design are adapted to the 90° corner layout of the workshop, and the protective surface is continuous and seamless. Attached Figure Description

The length is 10-30 mm to enhance the deformation resistance of the protective net; the through holes a6 and b10 are staggered on the adjacent surfaces of the support rod 1 to avoid bolt installation interference; the bottom of the support rod 1 is welded with a fixing plate 5, which is fixed to the ground by expansion bolts; multiple support rods 1 are arranged at intervals, and the protective net 2 covers the adjacent surfaces of the support rod 1 to form a continuous protective surface; the hook part of the hook bolt 3 supports the protective net 2 upward, and after the nut 4 is tightened, the threaded end of the hook bolt 3 is tightly fitted with the back of the support rod 1 to form a bidirectional force fixation.

[0034] 1. Manufacturing and fixing of support rods

[0035] The support rod 1 is made of angle steel or rectangular steel pipe, with a height of 1.5-2.0 meters. A fixing plate 5 is welded to the bottom of the support rod 1, with pre-drilled mounting holes. The support rod 1 is vertically fixed to the corner of the ground using expansion bolts. A right-angle groove 7 is machined at the top of the support rod 1, with a depth of 10-15 mm and a width slightly greater than the thickness of the hook part 8, ensuring that the protective net 2 can be quickly hung. Through holes a6 and b10 are respectively opened on two adjacent sides of the support rod 1 along the height direction. The two sets of through holes are staggered, with a spacing of 30-40 cm between them to avoid interference during bolt installation.

[0036] 2. Protective netting processing and installation

[0037] 1) Bending treatment of protective netting: bend the upper edge of the protective netting 2 to the back at 90 degrees to form a hook part 8, and bend the lower edge to the front at 30 degrees to form a step part 9. The bending lengths are 50 mm and 20 mm respectively.

[0038] 2) Pre-attach protective netting: Attach two protective nets 2 at 90° angles to each other on the adjacent sides of the support rod 1, align the hook part 8 with the right-angle slot 7, and press down lightly to make it fully embedded in the slot.

[0039] 3) Bolt tightening: Insert the hook bolt 3 from the front of the support rod 1, so that the hook end passes through the mesh of the protective net 2 and is inserted into the through hole a6 or through hole b10.
