[0024] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-4 , the preferred embodiments of the utility model are further described in detail:

[0026] like Figure 1-2As shown, a preferred drilling rig frame support frame of the utility model includes a base 1, a support base 2, a scissor-type lifting frame 4 and a lifting arm 5. The base 1 is correspondingly arranged below the support base 2, and the base 1 and the support base 2 are connected by two groups of scissor-type lifting frames 4, and the two groups of scissor-type lifting frames 4 are respectively arranged at the end positions on both sides of the base 1, and the lifting arm 5 is correspondingly arranged on the outside of the scissor-type lifting frame 4, the bottom end of which is fixed on the base 1, and the top end thereof passes through the support base 2 and extends upward, and the lifting arm 5 is used to drive the scissor-type lifting frame 4 to perform lifting movement, and the lifting arm 5 performs telescopic movement in a direction perpendicular to the base 1, and the lifting height of the vertically lifted lifting arm 5 is the changed height of the drilling rig frame 8. Therefore, the on-site construction personnel can determine the elevation change of the drilling rig frame 8 by the lifting height of the lifting arm 5, so that the on-site height adjustment is more intuitive and convenient for the construction personnel to operate;

[0027] The scissor lift frame 4 is a double-limb linkage scissor lift mechanism, comprising a scissor lift arm composed of a plurality of layers of hingedly connected scissor support rods 401. Two scissor support rods 401 in the same layer of the same scissor lift arm are hingedly connected at the middle of the rod bodies through a pin 403 to form an X-shaped scissor. The scissor support rods 401 of the same scissor lift arm and two adjacent layers of the X-shaped scissor are hingedly connected at the staggered end positions of the rod bodies through a pin 403.

[0028] The top end of the scissor support rod 401 of the top X-shaped scissors fork, which is located on the outside (the side close to the lifting arm 5), is hinged on the support seat 2 through a pin shaft 403, and the top end of the scissor support rod 401 of the top X-shaped scissors fork, which is located on the inside (the side away from the lifting arm 5), is hinged in a slide groove 3 provided on the support seat 2 through a pin shaft 403 and can slide along the slide groove 3;

[0029] The bottom end of the scissor support rod 401 of the bottom X-shaped scissors fork, located on the outside (the side close to the lifting arm 5), is hinged on the base 1 through a pin 403, and the bottom end of the scissor support rod 401 of the bottom X-shaped scissors fork, located on the inside (the side away from the lifting arm 5), is hinged in a slide groove 3 provided on the base 1 through a pin 403, and can slide along the slide groove 3;

[0030] The two sets of scissor lift arms are correspondingly hinged on the same connecting cross brace 402, and the connecting cross brace 402 is hingedly connected to the lift arm 5;

[0031] like Figure 3As shown, the lifting arm 5 includes an inner support tube 501, an outer sliding tube 502, a lifting cylinder 503 and a driving block 506. The bottom end of the inner support tube 501 is fixed on the base 1, and the outer sliding tube 502 is sleeved on the inner support tube 501 and can slide along the inner support tube 501. The lifting cylinder 503 is inserted into the inner support tube 501, and its bottom end is connected to the bottom end of the inner support tube 501 through a connecting shaft 504, and its top end is connected to the top end of the outer sliding tube 502 through a connecting shaft 504. The driving block 506 is arranged on the outer sliding tube 502, and the driving block 506 is hingedly connected to the connecting cross brace 402 through a hinge plate 507;

[0032] The driving block 506 can be directly fixed on the outer sliding tube 502. However, the fixed setting method has high requirements on the bearing capacity of the lifting cylinder 503. In order to better adapt to the jacking operation of large loads in the case of ultra-long drill pipes, it is advisable to consider the principle of labor-saving of movable pulleys and optimize the installation method of the driving block 506. At this time, a sliding groove 505 is opened on the outer sliding tube 502, and the driving block 506 is slidably embedded in the sliding groove 505 and can slide along the sliding groove 505. A chain 508 is fixed to the top of the driving block 506, and a guide pulley 509 is rotatably installed on the top of the outer sliding tube 502. The chain 508 bypasses the guide pulley 509 from bottom to top and extends downward along the vertical surface of the other side of the outer sliding tube 502 to the bottom of the inner support tube 501 and is fixedly connected to the inner support tube 501 or the base 1. Of course, the chain 508 can also be replaced by a wire rope;

[0033] Considering the on-site construction conditions, it is usually set that the scissor-type lifting frame 4 is set with two layers of X-shaped scissors to meet the construction requirements. Of course, when constructing a cavern with a larger diameter, the number of layers of the X-shaped scissors can be adjusted accordingly, wherein two groups of lifting arms 5 are preferably set, and the two groups of lifting arms 5 are arranged corresponding to the positions of the two groups of scissor-type lifting arms, respectively. The driving blocks 506 of the two groups of lifting arms 5 are connected to the same connecting cross brace 402 through hinge plates 507, that is, one end of the hinge plate 507 is hinged to the driving block 506 through a hinge shaft, and the other end is hinged to the connecting cross brace 402 through a hinge shaft. The connecting ear plates need to be welded in advance on the connecting cross brace 402 and the driving block 506. The connecting cross brace 402 is preferably set at the top position of the scissor support rod 401 of the bottom layer X-shaped scissors, which is located on the outside. The connecting cross brace 402 connects the two groups of scissor-type lifting arms of corresponding heights into one, so as to ensure that the two groups of lifting arms 5 synchronously drive the two groups of scissor-type lifting arms to move synchronously;

[0034] The base 1 and the support seat 2 are both rectangular frame structures connected by steel rods, which can better reduce the deadweight of the structure while playing a stable supporting role, and avoid structural components such as the lifting arm 5 and the telescopic arm 6 set on the frame;

[0035] The drilling rig frame 8 can be directly mounted on the support base 2 and supported by the support base 2. However, in this structural form, it is more troublesome to adjust the elevation angle of the drilling rig frame 8. For this reason, a telescopic arm 6 can be further provided. Figure 4 As shown, the telescopic arm 6 is correspondingly arranged at the end position of the support seat 2 beyond the base 1, and the top of the telescopic arm 6 is connected to the bottom of the drilling rig frame 8. The telescopic arm 6 includes an outer support arm 601, an inner sliding arm 602, a telescopic cylinder 603 and a connecting bracket 605. The outer support arm 601 is fixed on the support seat 2. In order to better utilize the space, the outer support arm 601 is preferably inserted into the frame of the support seat 2, and the fixed position of the two is preferably set at the top of the outer support arm 601. The inner sliding arm 602 is slidably inserted into the outer support arm 601. And it can slide along the outer support arm 601, the telescopic oil cylinder 603 is arranged in the inner sliding arm 602, and its bottom end is connected to the bottom end of the outer support arm 601 through a connecting pin 604, and its top end is connected to the top end of the inner sliding arm 602 through a connecting pin 604. The connecting bracket 605 is hinged to the top end of the inner sliding arm 602, and the connecting bracket 605 is fixed on the drilling rig frame 8. The setting of the telescopic arm 6 can, on the one hand, cooperate with the lifting arm 5 to increase the height adjustment range of the support frame, and on the other hand, it can also effectively adjust the elevation angle of the drilling rig to meet the on-site construction requirements;

[0036] As the excavation of the cavern progresses, the longitudinal positions of the drilling rig frame 8 and the support frame need to be advanced synchronously, and under the same excavation section, when supporting operations are performed on different parts, the lateral setting positions of the drilling rig frame 8 and the support frame also need to be adjusted. In order to more conveniently realize the position adjustment of the two, a walking walking system 7 is preferably installed at the bottom of the base 1. The walking walking system 7 is an existing mature technology, mainly including an upper chassis (the base 1 is used as its upper chassis in this application), a turntable, a walking system and other components. For details, please refer to the folding walking machine base disclosed in CN2832914Y or the dual-power-driven walking chassis disclosed in CN2925778Y, which will not be repeated here.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
