Problems solved by technology

[0002] At present, domestic similar drilling rigs can be roughly divided into two categories, one is anchor drilling rigs, such as attached figure 1 The one shown is an anchor drilling rig with a short stroke of the power head, which is mainly suitable for anchoring, micro-pile and pipe shed construction, but cannot realize high-efficiency large-depth rotary grouting construction; the other type is a special small rotary grouting Because the drilling rig has a short stroke and no jib components, it is necessary to frequently load and unload drill pipes, start and stop mud pumps and other equipment to realize rotary grouting during rotary grouting construction, which seriously affects the construction efficiency and the quality of rotary grouting piles. Efficient large depth rotary spraying construction
[0003] Since the drilling rig needs to be fed with high-pressure cement slurry and even air and water media during the rotary grouting construction, the existing drilling rig has a short stroke, generally 3-5m. If ultra-deep rotary grouting pile construction is required, Then it is necessary to frequently load and unload the drill pipe, and at the same time, it is necessary to start and stop the mud pump, air compressor or water pump. The working process is cumbersome and inefficient, and seriously affects the pile quality of the jet grouting pile

Embodiment 1

[0037] Such as Figure 2-5 As shown, a multifunctional drilling rig capable of rotary spraying construction, which can realize construction functions such as anchoring, micro-pile, pipe shed and high-pressure rotary spraying, includes a crawler chassis 1, a main engine 2, a luffing mechanism 3 and a main arm 4, The connection relationship between the crawler chassis 1, the main engine 2, the luffing mechanism 3 and the main arm 4 is the prior art, and they jointly form the basic module of the drilling rig, and also include a rotary spray assembly; the rotary spray assembly includes: auxiliary arm 7. Support, drilling tool 8, driving device 12 and clamping device 13;

[0038] The bottom end of the auxiliary arm 7 is connected to the top of the main arm 4, and the extension direction of the two is the same, and the auxiliary arm 7 is provided with a guide, and the guide can follow the chute on the auxiliary arm 7 and the main arm 4 slide;

[0039] The support is arranged on on...

Embodiment 2

[0046] Such as Figure 6-9 As shown, the difference between this embodiment and Embodiment 1 is that the support is a double-rod support, which includes a second support frame 5a, a second connecting rod 6a, a third connecting rod 6b, and a second threaded rod 10a and the third threaded rod 10b; the second support frame 5a is arranged on the main arm 4; the second connecting rod 6a and the third connecting rod 6b are arranged symmetrically, and the bottom ends of the two are respectively connected to the top of the second support frame 5a The two ends of the two are connected, and the tops of the two are respectively connected with one end of the second threaded rod 10a and the third threaded rod 10b, and the other ends of the second threaded rod 10a and the third threaded rod 10b are respectively connected to the secondary arm through the pin shaft 9 7 are connected in rotation; preferably, in order to improve stability, the extension lines of the second connecting rod 6a and...
