The compact drilling trolley of this embodiment includes a frame 9, on which a cab 8, an air compressor 11, an engine 12, a motor pump group 13, a water pipe reel 14, a hydraulic oil tank 15, a cable reel 16 and an electric control cabinet 17 are arranged. The engine 12 is arranged in the middle of the frame 9, the cab 8 is arranged at the front end of the engine 12, the air compressor 11 is arranged above the engine 12, the electric control cabinet 17 is arranged on both sides of the air compressor 11, the hydraulic oil tank 15 is arranged at the rear end of the frame 9, the motor pump group 13 is arranged between the air compressor 11 and the hydraulic oil tank 15, and the water pipe reel 14 and the cable reel 16 are arranged on both sides of the hydraulic oil tank 15 respectively.

[0029] The compact rock drilling trolley of the present embodiment has a drill arm arranged at the front end of a frame 9, a cab 8 arranged close to the drill arm, and a hydraulic oil tank 15 arranged at the rear end of the frame 9. The up-down, forward-backward, left-right space between the cab 8 on the frame 9 and the hydraulic oil tank 15 is fully utilized, and the engine 12, air compressor 11, motor pump group 13, two electric control cabinets 17, the water pipe reel 14 and the cable reel 16 are reasonably arranged, which can effectively reduce the width and length of the rock drilling trolley, making the whole rock drilling trolley compact and more suitable for the rapid construction of small and medium-section tunnels such as inclined shafts and cross tunnels.

[0030] The engine 12 is arranged in the middle of the frame 9, the air compressor 11 is arranged above the engine 12, the electric control cabinet 17 is arranged on both sides of the air compressor 11, and the motor pump group 13 is arranged at the rear side of the air compressor 11, which effectively reduces the width and length of the whole machine and is more suitable for small space tunnel construction applications such as inclined shafts.

[0031] like Figure 3As shown, in this embodiment, the cable reel 16 includes a pin shaft 91 arranged on the frame 9, a guide frame 161 hinged to the frame 9 through the pin shaft 91, and a reel body 162 arranged on the guide frame 161. The guide frame 161 is provided with a lug 163, and a detachable limit pin 164 for limiting the opening and closing of the guide frame 161 is arranged on the lug 163. A limit hole adapted to the limit pin 164 is arranged on the frame 9; the cable is wound around the reel body 162, and the cable is reeled and unreeled by the reel body 162 being rotated forward and reversely. The frame 9 and the guide frame 161 are hinged through the pin shaft 91, and the limit pin 164 is pulled out from the limit hole so that the guide frame 161 rotates around the pin shaft 91 as the axis, and the limit pin 164 is inserted to limit the rotation of the guide frame 161, so that the cable reel 16 can be opened for maintenance. Optionally, the limit hole includes a closed hole position and an open hole position. After the cable reel 16 is opened, the limit pin 164 is inserted into the open hole position, so that the cable reel 16 is always in the open state, to prevent the cable reel 16 from automatically closing and pinching the maintenance personnel; after the maintenance is completed, the limit pin 164 is pulled out from the open hole position, the guide frame 161 is rotated to close the cable reel 16, and then the limit pin 164 is inserted into the closed hole position, so that the cable reel 16 is always in the closed state.
