[0046] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0047] 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, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] See also Figures 1 to 7 A specific implementation method of a flip telescopic work platform and an anchor drilling vehicle is shown. The flip telescopic work platform can be used for drilling vehicle equipment for anchor / anchor cable support operations. When the workers perform anchor support operations, the vehicle body is far away from the coal wall, which makes the operation time-consuming and laborious. When working, the workers need to extend their bodies beyond the width of the vehicle body to perform anchor support operations. The flip telescopic work platform of this embodiment is installed on both sides of the anchor / anchor cable drilling vehicle lifting platform, taking into account the functions of protecting the side and preventing personnel from falling.

[0049] Specifically, Figure 1 and Figure 2 As shown, a flip telescopic work platform includes a lifting platform 100, a first drive unit 3, a fixed flap 2 and a movable flap 1.
