Wind shielding device for underground coal mine

Abstract

The invention relates to a wind shielding device for an underground coal mine, and the wind shielding device is capable of adjusting the area of a wind shielding plate, freely adjusting the inclination angle, direction and position of the wind shielding plate, reducing the resistance during operation and being folded and stored when not in use. The wind shielding device is characterized in that one end of a fixing seat is arranged on a underground aerial mancar in a sleeving manner; a groove is formed in the other end of the fixing seat, the width of the fixing seat is gradually reduced from one end to the other end, the two ends of the fixing seat are of protruding semi-arc structures, a rotating lug is arranged in the groove, one end of a horizontal rod is connected with the rotating lug, a universal ball joint is arranged at the other end of the horizontal rod, and a main supporting frame is arranged at the bottom of the universal ball joint through a fixing rod; the edge of one side of the main supporting frame is connected with one side of the side baffle, the other side of the side baffle bends and extends in the direction of the horizontal rod, a strip-shaped containing groove is formed in the other side of the main supporting frame, one side of the wind shield is arranged in the containing groove, an auxiliary supporting frame is arranged on the other side of the wind shield, and a containing groove is formed in one side of the auxiliary supporting frame.

Problems solved by technology

[0002] The official full name of the monkey car is the mine overhead passenger cableway, which is mainly used to assist the transportation of workers in underground mines. The ventilation speed in the interior is high, and the wind blows directly on the face and body of the staff. In addition, the staff is sweaty and the work clothes are wet after the task is completed, which can easily cause the staff to have colds, fevers and other physical discomforts. Personnel are exposed to wind and cold when riding on monkey cars. In the prior art, windshields are added to the front side of the monkey cars to block the wind. However, the existing windshield structures used for monkey cars have a fixed volume during use, which greatly increases the time required for the monkey cars. The original space occupied by the monkey car caused the monkey car to take up a lot of space when it was stored, making it inconvenient to store it afterwards. At the same time, it was impossible to flexibly adjust the size of the windshield according to the needs of use, so as to reduce wind resistance as much as possible

[0003] The notification number CN210502659U discloses a windshield device for a monkey car in a coal mine, including a windshield, a windshield connecting device, a first connecting rod, a second connecting rod, a first connecting ear, a second connecting ear and an elastic bolt device, The structure of the windshield of the device is fixed, and the size of the windshield cannot be adjusted freely. It takes up a lot of space and is not convenient for folding and storage.

[0004] Notification number CN211519484U discloses a variable direction windshield for a monkey car, including: a windshield; a connecting rod used to connect the windshield and the monkey car, the first end of the connecting rod is used to connect with the monkey car, and the connecting rod One of the second end of the second end and the windshield is provided with a pivot, and the other is provided with a mounting hole, and the pivot is rotatably installed in the mounting hole; the handle is fixedly connected with the windshield, and the windshield The size of the windshield is fixed and cannot be folded and stored, taking up a lot of space
