A force frame, a punching device and a rock stratum puncher
By installing a force-bearing frame on the drilling device, the downward pressure of an external force-applying object is used to improve the drilling efficiency of the drilling device by lever principle, thus solving the problem of insufficient drill rod weight due to the weight limitation of the drilling device.

AI Technical Summary
Technical Problem
Existing drilling devices have limited weight, resulting in relatively limited gravity on the drill rod and thus low drilling efficiency.
Method used
Design a force-bearing frame that is installed on a drilling device. By applying downward pressure from an external force-bearing object, the drilling efficiency of the device can be improved using the lever principle.
Benefits of technology
By designing a support frame, the drilling device can obtain greater downward pressure, thereby improving the hole-forming efficiency.

Abstract
This utility model provides a force-bearing frame, a drilling device, and a rock drilling machine, belonging to the field of engineering machinery. The drilling device is used for drilling into rock formations. The force-bearing frame includes two force-bearing beams, which are directly or indirectly connected. A force-bearing part is provided at the front end of the force-bearing frame for cooperating with a force-applying object. The rear ends of the force-bearing beams are spaced apart and connected to the drilling device. The drilling device includes a swing frame assembly, a drilling assembly, and a force-bearing frame. The drilling assembly is mounted on the swing frame assembly, and the rear end of the force-bearing frame is connected to the swing frame assembly. The force-bearing frame extends forward, allowing an external force-applying object to provide downward pressure to the drilling assembly through the force-bearing frame. Due to the forward extension of the force-bearing frame and the lever principle, the drilling device can obtain a large downward pressure, thereby improving the drilling efficiency.
