Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of coal mine inclined shaft personnel transportation, in particular to a rotatable wind shielding device of a mining monkey car. Background Art
[0002] The full name of the monkey car is the mine overhead passenger ropeway, which is mainly used for assisting the transportation of workers in underground mines. The steel wire rope is installed on the driving wheel, the supporting rope wheel, the pressure rope wheel, and the detour wheel and is tightened by the tensioning device. The driving device outputs power to drive the driving wheel and the steel wire rope to run, thereby realizing the principle of transporting miners.
[0003] It is often used in the auxiliary inclined shaft to transport miners. Its purpose is to shorten the travel time of miners going up and down the shaft and reduce the physical energy consumption of miners going up and down the shaft. During use, when miners ride on the monkey car to go up and down, due to the ventilation of the tunnel, there will be wind blowing on the passengers, which can easily cause colds. Especially in the northwest mining area in winter, the temperature is low and the coal mine requires a large amount of air. It is easy to induce problems such as wind chill when going up and down the shaft. Moreover, when going up and down the shaft, the passengers always face the forward direction, and the wind will come from the front and back. Therefore, the development of a rotatable wind shield to block the cold wind on the windward side when miners go up and down is of great significance to the physical health of miners and humanistic care.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example
[0022] like Figure 1-2 As shown, the rotatable windshield device of a mining monkey car described in this embodiment includes a fixed rod 2, a rotating arm 3, a windshield plate 4, and a counterweight 5. One end of the fixed rod 2 is connected to the main vertical rod 1 of the monkey car, and the other end is provided with a rotating shaft. The rotating arm 3 here is in the shape of a straight rod, and the rotating arm 3 spans the rotating shaft and is rotatably connected to the fixed rod 2 through the rotating shaft. The rotating arm 3 can rotate on a horizontal plane around the rotating shaft, and when a person rides on the monkey car, the rotating arm 3 is higher than the person's head and rotates in a horizontal plane above the person's head, which does not affect the person, and the person will not affect the rotation of the rotating arm 3.
[0023] In conjunction with the accompanying drawings, one end of the rotating arm 3 is connected to the windshield 4, and the other end is connected to the counterweight 5. The windshield 4 is in the shape of a vertical plate and is connected to the rotating arm 3 through a one-way rebound hinge. The windshield 4 rotates around the one-way rebound hinge in the direction away from the monkey car, and the axial direction of the rotating arm 3 is coplanar or parallel to the rotation plane of the windshield 4. The weight of the windshield 4 is balanced by the counterweight 5. The rotating arm 3 can rotate with the windshield 4 and the counterweight 5. Preferably, the rotating shaft is located on the center of gravity of the monkey car, which is conducive to the monkey car to maintain balance. The windshield 4 here is mainly to resist the wind blowing in the lane, and it is necessary to retain the field of vision when riding. In this example, the windshield 4 is a transparent acrylic plate. The wind blowing in the lane is from top to bottom. When riding, the personnel always face the direction of the monkey car. Therefore, when going down the well, the baffle needs to be located behind the personnel, and when going up the well, the baffle is located in front of the personnel. The front and rear position adjustment of the windshield 4 can be achieved by using the rotating arm 3.
[0024] When the rotating arm 3 rotates horizontally, it may be blocked by the main body vertical rod 1, so it is necessary to control the rotation angle range of the rotating arm 3 and the length of the rod from the rotating shaft to the counterweight block 5 to avoid the main body vertical rod 1 blocking the rotation. In this example, the fixed rod 2 is a straight rod, which is perpendicular to the main body vertical rod 1. The length of the rod from the rotating shaft to the counterweight block 5 is less than the length of the fixed rod 2. The length of the rod from the rotating shaft to the wind shield 4 does not need to be limited, and the wind shield 4 can also be guaranteed to rotate in the front and rear positions when going up and down the well.
[0025] Preferably, the rotating arm 3 in this example is provided with a fan ring guide rail 6. In conjunction with the accompanying drawings, the rotating arm 3 is cut into two sections by the fan ring guide rail 6, and the fan ring guide rail 6 is sleeved on the main body vertical rod 1 and slidably connected thereto. The fan ring guide rail 6 is a semicircular arc, and the fan ring guide rail 6 is provided with a buckle (not shown in the figure) that is engaged with the main body vertical rod 1. There are three buckles, which are respectively arranged at 0°, 90°, and 180° of the semicircular arc, as shown in the attached figure. Figure 1 The state at 90° is shown. When the rotating arm 3 rotates, the main body vertical rod 1 moves in the hole of the fan-shaped guide rail. The fan-shaped guide rail can provide three position buckles to facilitate the main body vertical rod 1 to maintain position. In this way, the fan-shaped guide rail can not only guide and limit the rotation of the rotating arm 3, but also use the buckles to achieve the three position holding function. Figure 2 It is shown that when ascending the well, the wind shield 4 is located in front of the body (position B, semicircular arc 0°), and when descending the well, the wind shield 4 is located behind the body (position C, semicircular arc 180°), and the wind shield 4 is reset to the position (position A, semicircular arc 90°).
[0026] The windshield 4 can rotate around the one-way rebound hinge away from the monkey car, the purpose is to avoid the possibility that when people get off the car, the windshield 4 is located behind them and affects the getting off. If the windshield 4 is fixedly connected, it will always remain vertical. When the windshield 4 is located behind them and goes down the well, the moment when the people get off the car will be hit by the windshield 4, and it is easy to bring people down, and there may be a safety accident. The windshield 4 of this example can rotate away from the monkey car. When the people get off the car, the windshield 4 is moved by the body, and then the windshield 4 rotates around the one-way rebound hinge to avoid bringing people down, ensuring safety. The one-way rebound hinge here is an existing product, which is only used here. Of course, it can also be replaced by other structural forms. The purpose is to be unidirectionally rotatable and resiliently reset. When resetting, the windshield 4 plays a windproof role, and it is unidirectionally rotating, and it will not rotate towards the direction close to the monkey car, that is, it can ensure the effect of windproofing against the wind direction (when the windshield 4 is located in front of the body and behind the body, it is all against the wind), and it will not affect the passengers.
[0027] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
