[0001] This invention relates to the field of mining equipment technology, and in particular to a connecting device and a transport vehicle. Background Technology

[0002] Traditional mobile shaft drilling rigs are mostly limited to a flared diameter of no more than 3 meters. When the flared diameter of a shaft drilling rig exceeds 3 meters, the required main components of the shaft drilling rig also become larger. However, most mine transport roadways in my country are relatively small, which restricts the use of large transport and lifting equipment. This makes it difficult to transport and relocate the main components of large-diameter shaft drilling rigs and to operate them for retrieval. In some cases, it is even necessary to disassemble and transport the main components of large-diameter shaft drilling rigs, which is not only time-consuming and labor-intensive, but also poses many safety hazards due to frequent lifting and disassembly.

[0033] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 5 According to one embodiment of the present invention, a connecting device includes a first rod group 100 and a second rod group 200. One end of the first rod group 100 is hinged to one end of the second rod group 200. The main body assembly of the well drilling rig is connected to the first rod group 100, and a drop frame 140 is also connected to the hinge point of the first rod group 100 and the second rod group 200. The function of the drop frame 140 is to support the main body assembly of the well drilling rig. (Refer to...) Figures 3 to 5 As shown, the drop frame 140 is provided in two sets. One set is connected to the hinge of the first rod group 100 and the second rod group 200, and the other set is connected to the main unit of the well drilling rig. When the main unit of the well drilling rig is completely unloaded from the transport vehicle, the two sets of drop frames 140 are used to support the weight of the main unit of the well drilling rig.

[0035] Reference Figure 1 , Figure 2 As shown, the first rod group 100 is hinged to one end with the first hydraulic cylinder 110, the second rod group 200 is hinged to one end with the first rod group 100 and to the other end with the second hydraulic cylinder 210, and the middle of the second rod group 200 is hinged to the transport vehicle.

[0036] In some specific embodiments of the present invention, the first rod assembly 100 includes two spaced-apart first arms 120 and a first connecting rod 130 for connecting the two first arms 120; the second rod assembly 200 includes two spaced-apart second arms 220 and a second connecting rod 230 for connecting the two second arms 220; the two first arms 120 are respectively hinged to the two second arms 220. Specifically, the well drilling rig main unit is connected to the two spaced-apart first arms 120, and the first arms 120 are provided with a plurality of connecting holes 123 for connecting to the well drilling rig main unit. Two first connecting rods 130 are provided and spaced apart to reinforce the connection between the two first arms 120.

[0037] In some embodiments of the present invention, the first boom 120 is provided with an embedding groove 121 on the side facing the second boom 220 for partial embedding of the first boom 120. Specifically, the purpose of providing the embedding groove 121 for the second boom 220 to be embedded is to further reduce space occupation. When the main unit of the well drilling rig is completely stored on the transport vehicle, the second boom 220 is partially inserted into the embedding groove 121, thereby enabling the main unit of the well drilling rig to be placed on the transport vehicle in a more horizontal manner, thus avoiding the left and right swaying of the main unit of the well drilling rig during transportation and making transportation more convenient.

[0038] In some embodiments of the present invention, both ends of the second boom 220 are bent in the same direction. Specifically, both ends of the second boom 220 are hinged to the second hydraulic cylinder 210 and the first rod assembly 100, respectively, and the middle part of the second boom 220 is hinged to the transport vehicle. The bending of both ends of the second boom 220 in the same direction can also be understood as the middle part of the second boom 220 being concave, so that the hinge position of the second boom 220 with the transport vehicle is lower than the hinge position of the second boom 220 with the second hydraulic cylinder 210 or with the first rod assembly 100. The purpose of this design is to better utilize the lever principle to realize the loading and unloading of the main components of the riser drilling rig.

[0039] In some embodiments of the present invention, the second rod assembly 200 further includes a support rod 240, which is disposed between the two second arm rods 220. A second connecting rod 230 passes through the support rod 240 to connect the support rod 240 and the second arm rod 220. The end of the support rod 240 is connected to the second hydraulic cylinder 210. Specifically, refer to... Figure 1 , Figure 2 As shown, there are two support rods 240 that are spaced apart, and part of the support rod 240 protrudes from the second arm 220. When the main unit of the well drilling rig is completely stored on the transport vehicle, the support rod 240 abuts against the first connecting rod 130 of the first rod group 100 to support the first rod group 100 and the main unit of the well drilling rig.

[0040] In some embodiments of the present invention, abutment rods 250 are provided at the ends of the two second arms 220 away from the first rod assembly 100, and the first arm 120 is provided with a hook groove 122 for the abutment rods 250 to be inserted. Specifically, the abutment rods 250 are hinged to the second hydraulic cylinder 210, and the ends of the abutment rods 250 extend beyond the ends of the second arms 220. The hook grooves 122 are provided at the ends of the first arms 120 away from the second rod assembly 200. The purpose of providing the hook grooves 122 and the abutment rods 250 is to better limit the first rod assembly 100 and bear part of the weight of the main components of the well drilling rig, so that the connection between the first rod assembly 100 and the second rod assembly 200 is more accurate, thereby reducing the thrust required by the second hydraulic cylinder 210.

[0041] According to the connecting device of the present invention, the main components of the well drilling rig can be quickly loaded and unloaded by connecting two hinged first rod groups 100 and second rod groups 200, which effectively improves loading and unloading efficiency, reduces the use of lifting equipment, and thus reduces safety hazards. The connecting device only includes the first rod group 100 and the second rod group 200, which has a simple structure, is easy to process, has low manufacturing cost, and is convenient for large-scale production.

[0042] Reference Figures 1 to 5Another embodiment of the transport vehicle of the present invention includes a front end 300, a frame 310, and the aforementioned connecting device. The frame 310 is provided with tracks 320, and the front end 300 is used to drive the tracks 320 to move. The first hydraulic cylinder 110 and the second hydraulic cylinder 210 are respectively hinged to different positions of the frame 310. Specifically, refer to... Figure 1 As shown, tracks 320 are installed on both sides of the chassis 310, and the front of the vehicle 300 is driven by an internal combustion engine to move along the tracks 320. The tracks 320 are suitable for various complex road conditions, have better passability, and are conducive to the transfer of main components of the well drilling rig.

[0043] Furthermore, the second hydraulic cylinder 210 is positioned closer to the connecting device, while the first hydraulic cylinder 110 is positioned closer to the front of the vehicle 300. Therefore, the second hydraulic cylinder 210 is shorter than the first hydraulic cylinder 110, but the initial starting torque of the second hydraulic cylinder 210 is greater than that of the first hydraulic cylinder 110. The second arm 220 of the second linkage 200 is hinged to the frame 310.

[0044] In some specific embodiments of the present invention, there are two first cylinders 110 and two second cylinders 210. The two first cylinders 110 are spaced apart and connected to the two first arms 120 respectively, and the two second cylinders 210 are spaced apart and connected to the two second arms 220 respectively.

[0045] The unloading method for the main components of the well drilling rig is as follows: Figures 3 to 5 As shown:

[0046] Figure 3 This is a schematic diagram of the positions of each component when neither the first hydraulic cylinder 110 nor the second hydraulic cylinder 210 is activated. At this time, the main body assembly of the well drilling rig is basically horizontally placed on the frame 310, which facilitates lowering the center of gravity of the main body assembly of the well drilling rig, and the main body assembly of the well drilling rig does not extend out of the frame 310, which facilitates transportation; at this time, the first rod group 100 and the second rod group 200 are in a mutually engaged state.

[0047] Figure 4 This is a schematic diagram showing the positions of each component when the second hydraulic cylinder 210 moves and the first hydraulic cylinder 110 moves accordingly. At this time, the second linkage 200 rotates at a certain angle around the hinge point with the frame 310, and due to the rotation of the first linkage 100, the first linkage 100 is driven to move, so the first hydraulic cylinder 110 also extends out at this time; at this time, the lowering frame 140 has also made contact with the ground.

[0048] Figure 5 This is a schematic diagram showing the positions of each component when the second and third hydraulic cylinders are both extended. At this time, due to the push of the first hydraulic cylinder 110, the first rod group 100 is basically in a vertical position. At this time, the main unit of the well drilling rig is completely vertical to the ground. The main unit of the well drilling rig is unloaded from the transport vehicle and can be used for further drilling operations.

[0049] Understandably, the loading and unloading procedures for the main components of the well drilling rig are reversed.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
