Description

Technical Field

[0001] The utility model relates to the field of mine belt conveyors, and particularly relates to a self - moving tail device for a belt conveyor used in a coal mine gate road. Background Technique

[0002] With the development of coal mining technology, belt conveyor self - moving tails are widely used in fully - mechanized coal mining faces underground in coal mines. They are intermediate connecting devices between gate road transfer conveyors and belt conveyors, with functions such as rapid propulsion, belt deviation adjustment, and height adjustment. However, their applicability is general. When there is a large steep downhill in the gate road, the connection between the self - moving tail and the belt conveyor often causes the belt to warp, vibrate, and coal to fall, and even serious safety accidents may occur.

[0003] Existing measures generally involve manually leveling the gate road floor or raising the position of the head end frame of the self - moving tail to make a relatively gentle transition with the belt conveyor to ensure normal coal transportation by the belt. However, this measure has poor operability and low economy, and it is difficult to completely solve the problem. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a self - moving tail device for a belt conveyor used in a coal mine gate road, which can solve the problems of belt warping, vibration, and coal falling at the connection between the belt self - moving tail and the belt conveyor under special working conditions, reduce safety risks, lighten the labor intensity of workers, and ensure normal coal transportation.

[0005] To achieve the above - mentioned purpose, the utility model proposes the following technical solutions:

[0006] A self - moving tail device for a belt conveyor used in a coal mine gate road includes a floating frame, a floating oil cylinder, a head end frame, a fuselage, a trolley, and a traveling oil cylinder. The head end frame is installed at the front end of the fuselage. One end of the head end frame is hinged to one end of the floating frame, and at the same time, the head end frame is hinged to the other end of the floating frame through the floating oil cylinder. The floating frame can be lifted or lowered under the action of the floating oil cylinder to adjust the belt tension or adapt to the height change of the belt conveyor. The trolley is installed above the fuselage and is connected to the transfer conveyor. The traveling oil cylinders are arranged on both sides below the fuselage and are used to drive the whole fuselage to move.

[0007] The floating frame is provided with a floating idler set, a lower belt idler, a floating coal baffle, wing plates, and a connecting frame. The floating frame, the floating idler set are connected to the belt conveyor.

[0008] The floating idler set includes a main idler and deviation - adjusting idlers arranged on both sides of the main idler. The floating idler set is arranged at the tail of the floating frame and is perpendicular to the running direction of the upper belt of the belt conveyor. The floating idler set is used to support the upper belt of the belt conveyor.

[0009] The lower belt idler is arranged on the floating frame. The lower belt idler is parallel to the floating idler group and is located below the floating idler group. The lower belt idler is used to support the lower belt of the belt conveyor.

[0010] There are two floating coal baffles, which are respectively arranged on both sides in the width direction of the floating frame, are placed outside the belt, and are arranged oppositely; the floating coal baffles are arranged vertically, and the length direction of the floating coal baffle is consistent with the length direction of the floating frame, and the floating coal baffle is placed above the floating frame; one end of the floating coal baffle is hinged to one end of the floating frame, and the other end of the floating coal baffle is hinged to the other end of the floating frame through a connecting frame, and both ends of the connecting frame are hinged.

[0011] The wing plate is obliquely arranged inside the floating coal baffle. The plane where the wing plate is located is parallel to the axis of the deviation adjusting idler. There is a gap between the wing plate and the deviation adjusting idler, so that the edge of the upper belt can be placed between the wing plate and the deviation adjusting idler to limit and guide the upper belt to a certain extent.

[0012] The combination of the floating coal baffle and the wing plate can reduce coal dropping, and at the same time, the wing plate can better limit and guide the upper belt to prevent the belt from warping and shaking.

[0013] Preferably, the lower belt idler is arranged inside the floating idler group.

[0014] Preferably, an inclined connecting plate is arranged inside the floating coal baffle. The wing plate is fixed on the inclined connecting plate through a pressing plate and bolts. The inclined angles of the inclined connecting plate and the wing plate are the same, further stabilizing the inclination degree of the wing plate.

[0015] Preferably, the wing plate is a rubber plate, which has a certain elasticity to reduce damage to the upper belt.

[0016] Preferably, the width of the wing plate is 0.1 - 0.3 of the length of the deviation adjusting idler.

[0017] Preferably, the length of the wing plate is 0.8 - 0.85 of the length of the floating frame.

[0018] Preferably, the floating coal baffle is located inside the floating idler group.

[0019] Preferably, the length of the floating coal baffle is 0.8 - 0.85 of the length of the floating frame.

[0020] Specifically, the floating frame, the floating idler group are connected to the belt conveyor. The upper belt of the belt conveyor is supported by the floating idler group, and the lower belt of the belt conveyor is supported by the lower belt idler.

[0021] Under special working conditions, such as when there is a large steep downhill in the gate roadway, the floating coal baffle on the floating frame can reduce coal falling. At the same time, the floating idler group supports the upper belt, and the lower belt idlers support the lower belt. The edge of the upper belt is placed between the deviation adjusting idlers and the wing plates, which can guide the upper belt well and prevent the belt from warping and jittering.

[0022] In order to adjust the belt tension or adapt to the height change of the belt conveyor, the floating frame will be lifted or lowered under the action of the floating oil cylinder. During the movement of the floating frame, the floating coal baffle and the wing plates will move accordingly. In different height states of the floating frame, it can reduce coal falling and prevent the belt from warping and jittering.

[0023] The beneficial effects of the present utility model are as follows:

[0024] By adding lower belt idlers on the floating frame and cooperating with the floating idler group, the present utility model realizes the guiding of the upper belt and the lower belt, and prevents the belt from warping and jittering.

[0025] By adding a floating coal baffle on the floating frame, the present utility model can reduce coal falling.

[0026] By arranging wing plates on the floating coal baffle, extending the length of the wing plates, and expanding the guiding range of the belt, the present utility model further limits and guides the upper belt to prevent the belt from warping and jittering.

[0027] Adopting the above scheme, the present utility model can solve the problems of belt warping, jittering and coal falling at the connection between the belt self - moving tail and the belt conveyor under special working conditions, reduce the safety risk, lighten the labor intensity of workers, and ensure the normal conveying of coal.
