In the field of building, down-the-hole hammer type pipe-following drilling equipment is common vertical drilling construction equipment, namely common construction equipment for drilling holes perpendicular to the ground. However, due to the structural limitation of the down-the-hole hammer type drill rod, the down-the-hole hammer type pipe following drilling equipment has high requirement on the height of the field space, and the drill bit part of the down-the-hole hammer type drill rod has heavy weight and large size, so that the drilling of the thin and short drill holes is difficult to realize, and therefore, the down-the-hole hammer type pipe following drilling equipment is particularly not suitable for drilling construction with complex geological environment and complex field environment.
For example, in the process of collapse prevention treatment in the subway construction process or in the process of treatment after the subway collapse is generated, excavation construction needs to be carried out after reinforcement is carried out on a crack zone, a broken zone and a collapse section of a foundation, but due to the influence of the structure of the underground hammer type pipe-following drilling equipment, the underground hammer type pipe-following drilling equipment cannot enter a construction site, and therefore the underground collapse prevention and treatment method is not suitable for the underground collapse prevention and treatment.

Wherein the top hammer rock drill 300 is slidably arranged on the feed beam 700 and is movable in a first direction, and the drill clamp 500 is arranged on the feed beam 700 near the front end. It should be noted that, in the present embodiment, the first direction refers to a length direction of the feed beam 700, for example, an x direction indicated in fig. 1, the second direction refers to a height direction of the feed beam 700, for example, a y direction indicated in fig. 1, and the third direction refers to a width direction of the feed beam 700, for example, a z direction indicated in fig. 1; the top hammer rock drill 300 described in the present embodiment moving in the first direction means that the top hammer rock drill 300 can advance and retreat in the first direction.
The main heel tube assembly 600 comprises a main drill rod and a main sleeve, wherein the main sleeve is sleeved on the main drill rod; the length of the main casing is less than the length of the main drill rod, so that the end of the main drill rod close to the top hammer rock drill 300 can be exposed out of the main casing, thereby facilitating the installation/extension of the main drill rod.

The first connection end of the main drill rod and the matching connection structure of the head of the main casing can refer to the connection structure of the drill rod and the casing in the down-the-hole hammer type casing drilling equipment, such as, but not limited to, chinese patent document No. 2012102948866 and chinese patent document No. 2003201152028.
The second link of kelly is connected with top hammer rock drill 300 drivably, namely, the power of the motion end of top hammer rock drill 300 can be transmitted to the second link of kelly, and this power both includes the rotatory rotational drive power of drive kelly, has also included the impact force that drives the kelly and gos forward to realize top hammer rock drill 300 to the drive of creeping into of kelly. The second connecting end of the main drill rod is in transmission connection with the top hammer type rock drill 300, namely, the second connecting end can be directly connected with the moving end of the top hammer type rock drill 300 and can also be connected through a transmission piece; in some scenarios, the transmission may be an additional drill rod 110, thereby increasing the drilling depth of the drill of the present embodiment.
For example, in drilling construction, if the design depth of the drill hole is high and the length of the main drill pipe and/or the main casing is less than the design depth of the drill hole, extension rods and/or adapter pipes are generally required to achieve an extension of the drilling depth. Meanwhile, in the embodiment, because the length of the main casing is smaller than that of the main drill rod, the drilling depth is usually extended only in two ways, namely, only connecting pipes are used for connecting the main casing and the main drill rod, namely, the length of the casing is extended; the other is to perform extension rods and joints, i.e. to extend the length of the drill pipe and casing.
In the first mode, the top hammer type rock drill 300 drives the main heel tube assembly 600 to drill from the rear end of the push beam, after the tail end of the main casing passes through the drill clamp 500, the drill clamp 500 clamps the main drill rod, the main drill rod and the top hammer type rock drill 300 complete rod disassembly, the top hammer type rock drill 300 returns to the rear end of the push beam, then the additional casing is sleeved on the main drill rod, the tail of the main casing is connected with the head of the additional casing, and then the top hammer type rock drill 300 moves to the second connecting end of the main drill rod to be connected with the main drill rod connecting rod, and the main heel tube assembly 600 is continuously driven to drill.
As for the second mode, after the tail end of the main casing passes through the drill clamp 500, the drill clamp 500 clamps the main drill rod, the main drill rod and the top hammer type rock drill 300 complete rod disassembly, the top hammer type rock drill 300 retracts to the rear end of the push beam, then the additional drill rod 110 is conveyed to the pipe connecting position, the first connecting end 111 of the additional drill rod 110 is connected with the second connecting end of the main drill rod, then the sheathing of the additional casing is completed, the connection between the additional casing and the main casing is completed, and the top hammer type rock drill 300 is moved to the second connecting end 112 of the additional drill rod 110 to be connected with the additional drill rod 110. The extension rod position of the additional drill rod 110 means that the additional drill rod 110 is placed on the feed beam 700 with the first connector 111 capable of driving connection with the main drill rod and the second connector 112 capable of being connected with the top hammer rock drill 300.
Of course, in some situations, when the pipe connecting/pipe connecting operation is required to be performed several times according to the designed depth of the borehole, the specific operation process may refer to the two manners described above, that is, after the main casing/additional casing at the end in the first direction passes through the drill clamp 500, the main drill pipe/additional drill pipe is clamped by the drill clamp 500, and then the pipe connecting/pipe connecting operation is performed.
In the following, the following description is given,

Wherein the bracket 201 is attached to the feed beam 700 such that the storage magazine 200 is attached to the feed beam 700. The rotating shaft 212 is rotatably connected to the bracket 201, and the rotating shaft 212 can rotate relative to the push beam 700, and specifically can be driven to rotate by the driving member 211; the rotating shaft 212 is further provided with at least two chucks 220, the chucks 220 are circumferentially provided with a plurality of bayonets, the bayonets at corresponding positions on different chucks 220 form clamping positions together, and the additional drill rod 110 is clamped in the clamping positions and can rotate relative to the support 201 along with the rotating shaft 212.
A stop 230 is provided on the carriage 201, the stop 230 being adapted to stop the additional drill rod 110 in the stored condition from being removed from the magazine 200. The storage state refers to a state in which the additional drill rod 110 is accommodated in the magazine 200 when the extension rod is not needed. In addition, the stopping portion 230 is further provided with a notch 231 for allowing the additional drill rod 110 to be removed from the storage magazine 200, and when the rotating shaft 212 rotates relative to the push beam 700, the rotating shaft also rotates relative to the stopping portion 230; when the rotating shaft 212 is rotated to a specific position, one of the additional drill rods 110 clamped on the chuck 220 is located at a position corresponding to the notch 231, i.e., in a standby state, and the robot 240 can take out the additional drill rod 110 from the magazine 200 and transport it to the extension rod position. The standby state means a state in which the additional drill rod 110 can be transported to the position of the extension rod to extend the extension rod.
Referring to fig. 2, an additional casing 120 may be further provided on the additional drill rod 110, the additional drill rod 110 and the additional casing 120 together form an additional casing follower assembly 100, and the additional casing follower assembly 100 is accommodated in the magazine 200, so that the robot 240 can simultaneously complete the handling of the additional casing 120 while handling the additional drill rod 110, thereby improving the efficiency of the take-over and extension rod.
Both ends of the additional sleeve 120 are provided with a first connection part 121 and a second connection part 122, respectively. Wherein, the first connection part 121 is used to connect with the tail part of the main casing, and when a plurality of additional casings 120 are connected to the drill rod of the present embodiment, the additional casing 120 at the front end is connected with the first connection part 121 of the additional casing 120 at the rear end through the second connection part 122 to implement a connection pipe.
