Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of tunnel or underground engineering rock drilling equipment, especially relates to a rock drilling device and rock drilling jumbo. BACKGROUND

[0002] The rock drilling jumbo is a kind of rock drilling equipment for tunnel or underground engineering, mainly used for drill and blast method construction. The core working device is rock drilling machine, which is installed on the advancing beam. The advancing beam is also provided with front end drill holder, middle drill holder, advancing cylinder, steel wire rope and movable pulley and other components. The advancing beam is the supporting and positioning mechanism of the rock drilling machine, while the advancing cylinder, steel wire rope and movable pulley constitute the advancing mechanism of the rock drilling machine, which can move the rock drilling machine on the advancing beam. The output shaft of the rock drilling machine is connected with drill rod, and the other end of the drill rod is connected with drill bit. The rock drilling machine rotates and impacts the drill rod by driving, and performs drilling operation on the working surface. At the same time, the advancing cylinder drives the rock drilling machine to feed, and completes the drilling work.

[0003] Since the drilling depth of the rock drilling machine is limited by the length of the drill rod, and the length of the single drill rod is limited by the length of the advancing beam, when the drilling depth exceeds the parameter range of the advancing beam, the prior art usually adopts the following methods:

[0004] Method one: manual connection of rods. Multiple drill rods are connected one by one manually to increase the drilling depth. However, this method has high labor intensity, and workers need to work at the front end of the tunnel excavation, which increases the risk factor.

[0005] Method two: use of super-long single drill rod. A single drill rod longer than the advancing beam is used. However, this method is prone to bending of the drill rod when the drill bit starts to drill the working surface, and the drill bit deviates from the predetermined hole position, resulting in inaccurate hole position.

[0006] Method three: with rod clamping device. A drill rod is installed on the clamping device, and a front end clamping device is arranged at the front end of the advancing beam to replace the front end drill holder. When the rock drilling machine drives the first drill rod into the working surface, the front end clamping device clamps the drill rod, the output shaft of the rock drilling machine is reversed to loosen the connection with the first drill rod and disengage. Then, the clamping device sends the second drill rod to the rod connection position, the rock drilling machine is connected with the second drill rod and continues to drill. However, this method can only add one drill rod, and the drilling depth is limited. If deeper holes need to be drilled, manual rod connection method still needs to be used.

[0007] In addition, some rock drilling jumbos are equipped with a large rod storage and rod connection and delivery device, which can connect multiple drill rods. However, this design is bulky and not suitable for small cross-section construction sites such as mine roadway, water and electricity tunnel and the like. These sites have strict requirements on the flexibility and size of construction machinery, and currently there is no such device applied on small rock drilling jumbos. CONTENT OF THE UTILITY MODEL

[0014] In the tunneling rock drilling device, preferably, the push rod device and the clamping device are arranged on the same side of the advancing beam, and the push rod device is located below the side of the gripper. The push rod device and the gripper are staggered in space, avoiding mutual interference in the process of pushing the drill rod and clamping by the clamping device, improving the smoothness and reliability of the device operation, and arranging the push rod device and the clamping device on the same side of the advancing beam makes the overall structure more compact and the spatial layout more reasonable.
