Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for underground conveyors in coal mines, and more specifically, to a quick-release, pluggable, anti-tumble protective net. Background Technology

[0002] Safety nets are now essential equipment for material conveying in underground coal mines. The safe operation of belt conveyors is crucial to the overall production efficiency of the mine and the safety of miners. Due to the complex environment and limited space in underground coal mines, or the need to arrange belt conveyors on slopes, multiple pieces of equipment are often arranged in the same roadway. Personnel passing by or conducting safety inspections pose a risk of accidental falls and contact with the operating belt conveyor, especially in sloped roadways, where there is a risk of spilled or splashed materials. Conventional safety nets are fixed to the conveyor frame, with only one fixing point, making them susceptible to overturning under stress, causing frame damage and downtime. Simple hanging safety nets are prone to edge warping, lower body swaying, or detachment. Routine maintenance of conveyors is also a necessary part of daily coal mine production, requiring safety nets that are easy to disassemble and allow maintenance workers to easily observe and replace damaged parts of the transport equipment. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a safety net is provided that can be quickly assembled and disassembled, prevents material spillage and splashing, prevents overturning, and is easy to fix.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A quick-release, hook-and-mount anti-tumbler protective net includes:

[0006] The main beam has an installation structure on one side and a wire mesh structure on the other side.

[0007] The upper protective netting includes an upper frame and netting panels. The upper frame has upper retaining rings on both sides that cooperate with the netting structure. The netting panels are installed on the upper frame.

[0008] The lower protective netting includes a lower frame and a lower mesh panel. The upper sides of the lower frame are equipped with lower retaining rings that cooperate with the hanging netting structure, and the lower mesh panel is set on the lower frame.

[0009] The main beams are installed on the intermediate frame channel steel of the belt conveyor through an installation structure. There are at least two main beams, and upper and lower protective nets are installed between adjacent main beams.

[0010] Preferably, the installation structure includes an upper hook and a lower fastening hook. The upper hook is fixedly connected to the main beam, and the lower fastening hook is detachably connected to the main beam. The upper hook and the lower fastening hook respectively hook onto the upper edge and lower edge of the channel steel of the intermediate frame of the belt conveyor.

[0011] Preferably, the hanging structure includes a first curved hook, a second curved hook, a third curved hook, and a fourth curved hook arranged sequentially from top to bottom. The upper frame is hung on the first curved hook via an upper retaining ring, and the lower end of the upper frame is inserted into the second curved hook. The lower frame is hung on the third curved hook via a lower retaining ring, and the lower end of the lower frame is inserted into the fourth curved hook.

[0012] Preferably, the main beam is provided with mounting holes, and one end of the lower fastening hook passes through the mounting holes and is threaded with a wing nut.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. This utility model achieves rapid installation and stable fixation through modular design (the main beam, upper and lower protective nets, and base can be flexibly assembled) and double hook structure. Its netting structure achieves rapid installation through the interlocking of multi-layer bent hooks and protective netting clips. Combined with the multi-directional constraint of the main beam and terrain adaptability adjustment function of the limiting rectangular steel base, it effectively prevents the protective net from tilting.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] like Figures 1 to 9 As shown, a quick-release, pluggable, fixed, anti-tilting protective net includes four parts: a main beam 1, an upper protective net 2, a lower protective net 3, and a base 4. The main beam 1, upper protective net 2, lower protective net 3, and base 4 adopt a modular design, allowing for assembly to the required length according to the direction of the belt conveyor. The main beam 1 is mounted on the channel steel of the intermediate frame of the belt conveyor via an installation structure. At least two main beams 1 are provided, with an upper protective net 2 and a lower protective net 3 installed between adjacent main beams 1. The base 4 is located at the lower end of the main beam 1.

[0031] A mounting structure is provided on one side of the main beam 1, and a mesh hanging structure is provided on the other side. Specifically, the mounting structure includes an upper hook 1.1 and a lower fastening hook 1.2. Mounting holes for the upper hook 1.1 and lower fastening hook 1.2 are machined in the middle of the main beam 1. The upper hook 1.1, according to the dimensions of the intermediate frame channel steel, passes through the main beam 1 and is welded and fixed. One end of the lower fastening hook 1.2 passes through the mounting hole and is threaded with a wing nut 1.7. During installation, the main beam 1 is tilted so that the upper hook 1.1 hangs on the upper edge of the intermediate frame channel steel. Then, the main beam 1 is rotated to make it vertical. The lower fastening hook 1.2 is adjusted so that it hangs on the lower edge of the intermediate frame channel steel and is tightened with the wing nut 1.7. The design of the mounting holes ensures reasonable stress distribution on the main beam 1 and prevents shearing.

[0032] The hanging net structure includes, from top to bottom, a first curved hook 1.3, a second curved hook 1.4, a third curved hook 1.5, and a fourth curved hook 1.6.

[0033] The upper protective netting 2 includes an upper frame 2.2 and netting panels 2.1. Both sides of the upper end of the upper frame 2.2 are equipped with upper retaining rings 2.4 that mate with the first curved hooks 1.3. During installation, the upper retaining rings 2.4 are hooked onto the first curved hooks 1.3, and the lower ends of the upper retaining rings 2.4 are inserted into the second curved hooks 1.4, thus securing the upper protective netting 2. Reinforcing angle steel I 2.3 is installed on the upper frame 2.2 to enhance its structural strength.

[0034] The lower protective netting 3 includes a lower frame 3.2 and a lower mesh panel 3.1. Both sides of the upper end of the lower frame 3.2 are equipped with lower retaining rings 3.3 that mate with the third curved hook 1.5. During installation, the lower retaining rings 3.3 are hooked onto the third curved hook 1.5, and the lower ends of the lower retaining rings 3.3 are inserted into the fourth curved hook 1.6, thus securing the lower protective netting 3. A reinforcing angle steel II 3.4 is installed on the lower frame 3.2 to enhance its structural strength.

[0035] The upper protective net 2 and the lower protective net 3 can be made in different sizes according to the needs of the protected parts.

[0036] The upper protective net 2 and the lower protective net 3 must not be installed in reverse, as this will not provide a secure fixation effect.

[0037] The base 4 consists of a base plate 4.1 and a limiting rectangular steel 4.2. The rectangular tube at the bottom of the main beam 1 slides into the limiting rectangular steel 4.2, limiting its movement left, right, forward, and backward, while allowing for vertical adjustment. This facilitates the placement of the protective netting along the terrain, better fulfilling its functional requirements and achieving safety objectives. The base plate 4.1 has connecting holes, allowing the base 4 to be secured with expansion bolts after proper installation and adjustment. The use of this base 4 prevents the protective netting from tipping over or turning over under stress.

[0038] Instructions for use: The upper protective net 2 is hung on the first curved hook 1.3 via the upper retaining ring 2.4, with its lower end inserted downwards into the second curved hook 1.4; the lower protective net 3 is hung on the third curved hook 1.5 via the lower retaining ring 3.3, with its lower end inserted downwards into the fourth curved hook 1.6. The installation of the upper protective net 2, lower protective net 3, and base 4 can be adjusted to a certain angle to accommodate the undulations of the conveyor.

[0039] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
