Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor safety protection technology, specifically a convenient belt conveyor protective net. Background Technology
[0002] Belt conveyors are commonly used conveying equipment in coal processing and transportation. The function of belt conveyor guards is to prevent material from splashing and to prevent damage to the belt conveyor from falling rocks from the mine roof, thereby ensuring production safety.
[0003] However, the existing belt conveyor safety nets are mainly constructed by three sets of safety nets, which are used to protect the top and sides of the belt conveyor, resulting in high investment costs. Secondly, the safety net at the top is horizontal, making it easy for rocks from the top of the mine to accumulate on top. When too many rocks accumulate, they need to be cleaned up in time, but the belt conveyor is long, making the cleaning process quite troublesome. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a convenient belt conveyor guard net. This convenient belt conveyor guard net can protect the top and sides of the belt conveyor with two sets of protective nets. Compared with the traditional three sets of protective nets to protect the top and sides of the belt conveyor, its investment cost is lower, and its top does not accumulate rocks from the mine top, making it more convenient to use.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A portable conveyor belt guard includes two sets of external reinforcing frames, and each set of reinforcing frames has a crisscrossing protective net welded and fixed inside.
[0007] The two sets of external reinforcement frames are rotatably installed together via a connecting shaft. After rotatable installation, the two sets of external reinforcement frames are erected and fixed directly above the belt conveyor.
[0008] Two sets of external reinforcement frames and protective nets are installed at an angle from the middle of the belt conveyor to both sides, like a roof. At this time, the two sets of external reinforcement frames and protective nets can protect the top and sides of the belt conveyor.
[0009] Using the above solution, this portable belt conveyor guard can protect the top and sides of the belt conveyor with two sets of guard nets. Compared with the traditional three sets of guard nets for the top and sides of the belt conveyor, it has a lower investment cost and does not accumulate rocks from the top of the mine, making it more convenient to use.
[0010] As a preferred embodiment of a convenient belt conveyor safety net, the bottom of the belt conveyor is welded and fixed with support legs. The bottom of the outer reinforcing frame and the support legs are reinforced and fixed by an adjustment and positioning mechanism. The adjustment and positioning mechanism includes an adjustment part and a positioning part. The adjustment part is installed at the bottom of the outer reinforcing frame, and the positioning part is installed on the support legs. The distance between the adjustment part and the positioning part can be adjusted by adjusting the adjustment part, thereby adjusting the tilt angle of the two sets of outer reinforcing frames and the safety net.
[0011] By adopting the above scheme, in order to strengthen the fixation of the external reinforcement frame and adjust its tilt angle, the tilt angle of the two sets of external reinforcement frames and protective nets can be adjusted by changing the distance between the adjustment part and the positioning part during use, so as to adapt to different application scenarios and improve its application flexibility.
[0012] As a preferred embodiment of a portable conveyor belt guard, the adjustment part includes an adjustment base with rotating shafts fixed at both ends. The adjustment base is rotatably mounted in a clearance groove at the bottom of the outer reinforcing frame via the rotating shafts. A screw is rotatably mounted inside the adjustment base, facing the positioning part. The screw is threaded only near the positioning part, and two limiting stops are fixed on the shaft of the screw at the front and rear of the adjustment base. A rotating handle is fixed at the end of the screw near the adjustment base.
[0013] The positioning part includes a positioning base, a nut fixed at the center of the positioning base, and a screw that engages with the nut via threads; a limit stop is fixed at the end of the screw near the positioning base; and J-shaped hooks are detachably installed at both ends of the positioning base by screws, which are hooked onto the support legs.
[0014] Using the above solution, when operating the adjustment section, the screw is rotated by turning the rotary handle. With the help of the thread, the distance between the adjustment base and the positioning base can be quickly adjusted, thereby adjusting the tilt angle of the two sets of external reinforcement frames and the protective net. The operation is simple and convenient and can be carried out without the need for tools.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are:
[0016] 1. This portable belt conveyor guard net can protect the top and sides of the belt conveyor with two sets of guard nets. Compared with the traditional three sets of guard nets to protect the top and sides of the belt conveyor, it has a lower investment cost and does not accumulate rocks from the top of the mine, making it more convenient to use.
[0017] 2. In order to strengthen the fixation of the external reinforcement frame and adjust its tilt angle, the tilt angle of the two sets of external reinforcement frames and protective netting can be adjusted by changing the distance between the adjustment part and the positioning part during use, so as to adapt to different application scenarios and improve its application flexibility.
[0018] 3. When operating the adjustment section, the screw can be rotated by turning the rotary handle. With the help of the thread, the distance between the adjustment base and the positioning base can be quickly adjusted, thereby adjusting the tilt angle of the two sets of external reinforcement frames and the protective net. The operation is simple and convenient and can be carried out without the need for tools. Attached Figure Description
