Onboard front detecting beam for development machine

The utility model relates to an onboard front detecting beam for a development machine. The onboard front detecting beam comprises a front detecting beam top beam. Side overturning plates connected through hinges are arranged on the two sides of the front detecting beam top beam respectively, the lower planes of the side overturning plates are provided with clamping grooves, and E-shaped plates are clamped in the clamping grooves and can be pushed and pulled in the clamping grooves. The onboard front detecting beam for the development machine is simple in structure, a normal cutting operation function of the development machine is not disturbed, an anchor mesh and a steel strip or groove steel can be supported while the temporary support is met, mechanical supporting operation is achieved, the operation strength is reduced, the tunneling efficiency is improved, and the safety of anchor support workers is effectively guaranteed.
