Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0039] Please refer to Figure 1 The diagram shows a structural schematic of the construction machinery provided in this embodiment of the present invention, including a drilling carrier 4 and a drilling device. The drilling device includes a drilling assembly 1 and a support frame 2. The drilling assembly 1 includes a drill rod support 11 and a drill rod 12 rotatably connected to the drill rod support 11. The drill rod support 11 supports the drill rod 12, and the drill rod 12 is driven to rotate by a drive member 114 mounted on the drill rod support 11 to achieve drilling. The drill rod support 11 is connected to the drilling carrier 4, which is used to carry the drilling device. The drilling carrier 4 can be an excavator, which has a power unit and a control unit. The excavator provides a power source for the drilling device and controls the drilling device. The drilling carrier 4 can also be other power platforms with a power unit and a control unit.

[0040] This embodiment provides a support frame 2, such as Figure 1The force-bearing frame 2 is used to install on the drilling assembly 1. The installation method is preferably detachable, which facilitates installation on any drilling assembly 1, allows for application to multiple drilling assemblies 1, and facilitates transportation of the drilling device after disassembly. The force-bearing frame 2 includes a connecting end 21, an extension arm 22, and a force-bearing structure 23. The connecting end 21 is connected to the drill rod support 11, and the extension arm 22 extends from the connecting end 21 away from the drill rod support 11. The force-bearing structure 23 is located at the distal end of the extension arm 22 and is used to receive external forces and transmit them to the drill rod 12. By providing the force-bearing structure 23 extending to the distal end of the drill rod 12 assembly, it can receive the gravity or applied forces from other equipment such as the jacking device 3, gravity blocks, or other equipment, and then transmit the forces from other equipment to the drill rod 12 through the force-bearing structure 23. This allows the drill rod 12 to obtain greater gravity during drilling, thereby improving drilling efficiency.

[0041] Reference Figure 3 As an example, the aforementioned extension arm 22 includes a crossbeam 222 and two opposing longitudinal beams 221. The crossbeam 222 connects the two longitudinal beams 221. The two longitudinal beams 221 are respectively positioned opposite each other on both sides of the drill pipe support 11 and extend in a direction away from the drill pipe support 11. The crossbeam 222 connects the two longitudinal beams 221 near their distal ends, serving to connect the two longitudinal beams 221 and improve their stress stability. The force-bearing structure 23 is positioned between the distal ends of the two longitudinal beams 221, forming the force-bearing fulcrum of the longitudinal beams 221. The longitudinal beams 221 constitute the lever arm for transmitting forces. When the force-bearing structure 23 is subjected to external forces, the force can be transmitted to the drill pipe support 11 through the longitudinal beams 221 on both sides of the drill pipe support 11. Since the drill pipe 12 is mounted on the drill pipe support 11, the force can be transmitted to the drill pipe 12, thereby helping the drill pipe 12 to obtain greater gravity.

[0042] Furthermore, the aforementioned longitudinal beam 221 may be irregular in shape, with its distal end slightly inclined downwards to facilitate better stress distribution.

[0043] As an example, the aforementioned load-bearing structure 23 may include at least one pulley, the pulley's axis of which is perpendicular to the two longitudinal beams 221. The pulley's axle is rotatably connected to the ends of the two longitudinal beams 221, allowing the pulley to rotate. Thus, when other equipment applies a force to the pulley, sliding friction between it and the load-bearing structure 23 can be avoided, preventing damage to both the equipment and the load-bearing structure 23. The pulley's design achieves rolling friction, thus preventing damage.

[0044] Furthermore, multiple pulleys can be provided, preferably two, with the two pulleys arranged opposite each other, thereby forming a downward force support point and an upward force support point to assist the drill rod 12 in drilling and upward movement.

[0045] like Figure 1In one specific embodiment, when the device used for the force-bearing structure 23 is a jacking device 3, the jacking device 3 includes a jacking carrier 31 and a jacking support 32. The jacking support 32 can cooperate with the force-bearing structure 23 by setting a force-applying structure 33. The force-applying structure 33 is driven to move up or down by a lifting cylinder, applying an upward lifting force or a downward force to the force-bearing structure 23. When the force-applying structure 33 moves downward to apply a force, if its downward moving speed is greater than the downward moving speed of the force-bearing structure 23 with the drill pipe 12, the jacking support 32 will move upward under the action of the reaction force. This easily drives its front part to move upward, while its lower rear end is always in contact with the rock layer. This causes the front part of the jacking carrier 31 and the jacking support 32 to rotate relative to the rock layer around the lower rear end of the carrier. During this rotation, the force-applying structure 33 will move forward relative to the force-bearing structure 23. The pulley structure enables the force-applying structure 33 to roll and rub against it, thereby avoiding damage to both. When the force-applying structure 33 moves upward to apply lifting force, it first moves to below the force-receiving structure 23, and then drives it to move upward through the lifting cylinder to apply lifting force to the force-receiving structure 23.

[0046] Reference Figure 3 As an example, the aforementioned force-bearing structure 23 may include at least one block structure 231, which extends away from the drill pipe support 11. The block structure 231 is a strip-shaped block that can be connected between two longitudinal beams 221 via connecting rods, extending away from the drill pipe support 11 to facilitate the formation of a force-bearing fulcrum and receive applied forces. When the force-bearing structure 23 is set as a block structure 231, the force-applying structure 33 of the jacking device 3 can be set as a pulley, thus achieving rolling friction and reducing damage. Furthermore, the cooperation between the pulley and the block structure 231 is a line-to-line cooperation in both the transverse and longitudinal directions, which greatly improves the ease of cooperation between the force-bearing structure 23 and the force-applying structure 33.

[0047] Furthermore, multiple block structures 231 can be provided, preferably two. The two block structures 231 are arranged opposite each other to form a downward force support point and an upward force support point, which assist the drill rod 12 in drilling and upward movement.

[0048] Reference Figure 2In this embodiment, the drill pipe support 11 includes a first support 111 and a second support 112. The first support 111 is rotatably connected to the drilling carrier 4 via a connecting frame 41. Specifically, one end of the connecting frame 41 is hinged to the drilling carrier 4, and the other end of the connecting frame 41 is hinged to the first support 111. A rotating cylinder 42 is provided on the connecting frame 41, with one end of the rotating cylinder 42 hinged to the connecting frame 41 and the other end of the rotating cylinder 42 hinged to the first support 111. A lifting cylinder 43 is provided on one or both sides of the connecting frame 41, with one end of the lifting cylinder 43 hinged to the drilling carrier 4 and the other end of the lifting cylinder 43 hinged to the first support 111. The rotation of the drill pipe support 11 can be achieved through the connecting frame 41, the rotating cylinder 42, and the lifting cylinder 43, facilitating transportation. Specifically, the lifting cylinder 43 can limit the height of the front end of the connecting frame 41 in the vertical direction, and the rotating cylinder 42 can limit the angle between the connecting frame 41 and the first support 111. During transportation, the upper part of the first support 111 is the highest point of the drill bit. The lifting cylinder 43 and the rotating cylinder 42 work together to limit the upper part of the first support 111 within the transportation height limit range.

[0049] The second support 112 is slidably mounted on the first support 111, and the second support 112 and the first support 111 are connected by a lifting drive mechanism, preferably a lifting cylinder 113. The drill rod 12 is connected to the driving component 114 mounted on the second support 112. That is, the first support 111 is fixed, the lifting cylinder 113 drives the second support 112 and the drill rod 12 to move up or down synchronously, and the driving component 114 drives the drill rod 12 to rotate at high speed, cooperating with the lifting cylinder 113 to achieve downward drilling or upward return of the drill rod 12. The two longitudinal beams 221 are connected to both sides of the first support 111 or both sides of the second support 112 through connecting ends 21, that is, the force-bearing frame 2 can be connected to the first support 111 or the second support 112. When the force-bearing frame 2 is connected to the first support 111, it remains fixed during drilling; when the force-bearing frame 2 is connected to the second support 112, it moves up and down synchronously with the second support 112 and the drill rod 12 during drilling.

[0050] Furthermore, to prevent interference between the load-bearing frame 2 and the transport vehicle during the transportation of the drilling device, the load-bearing frame 2 is detachably connected to the first bracket 111 or the second bracket 112. It should be noted that when the drilling device is in the transportation state, its drill rod bracket 11 and drill rod 12 are tilted. If the load-bearing frame 2 is integrally connected to the drill rod bracket 11, it is easy to interfere with the transport vehicle if its length is long.

[0051] Reference Figures 5-7As an example, first connectors 115 are respectively provided on both sides of the first bracket 111 or the second bracket 112, preferably on both sides of the first bracket 111, so as to make the operation more stable. Second connectors 201 are respectively provided on both sides of the connecting end 21, and the first connectors 115 and the second connectors 201 are engaged.

[0052] Furthermore, the first connector 115 may be a locking block or a locking slot, and the second connector 201 may be a locking slot or a locking block that is adapted to engage with it.

[0053] Specifically, when the first connector 115 is a locking block, the second connector 201 is a downward-facing locking groove. During connection, the locking groove of the force-bearing frame 2 is engaged with the locking block from top to bottom. The locking block passes through the locking groove laterally and can cooperate with the groove to restrict the longitudinal movement of the locking block relative to the locking groove.

[0054] Alternatively, when the second connector 201 is a locking block, the first connector 115 is an upward-opening locking groove. During connection, the locking block of the force-bearing frame 2 is moved from top to bottom and locked into the locking groove. The locking block passes through the locking groove laterally and can cooperate with the groove to restrict the longitudinal movement of the locking block relative to the locking groove.

[0055] Understandably, in order to improve connection stability, two sets of first connectors 115 and second connectors 201 are provided on the same side of the drill pipe bracket 11. The two first connectors 115 are arranged vertically and horizontally on the bracket, and the two second connectors 201 are arranged vertically and horizontally at the upper and lower ends on the same side of the connection end 21, respectively opposite to the first connectors 115.

[0056] Furthermore, a limiting card 116 is provided at the opening of the card slot. The limiting card 116 is fixed to both ends of the opening of the card slot by a pin to close the opening and prevent the card block from coming out of the groove.

[0057] Since the load-bearing frame 2 needs to withstand a large force, if bolts or pins are used to connect the load-bearing frame 2 to the drill pipe bracket 11, the bolts and pins are relatively large, which makes installation inconvenient. This application, through the above structural design, allows for easy installation of the load-bearing frame 2 by simply engaging the locking block with the locking slot from above, and then installing the limiting card 116. Removal is achieved by reversing the steps; compared to bolt and pin connections, the locking mechanism is more convenient.

[0058] Reference Figure 4As an example, the first support 111 is provided with a first support base 13 at its bottom end, and the second support 112 is provided with a second support base 14 at its bottom end; the first support base 13 and the second support base 14 can simultaneously contact the transport vehicle. The first support base 13 can be integrally connected to or detachably connected to the bottom end of the first support 111, and the second support base 14 can be integrally connected to or detachably connected to the bottom end of the second support 112. By providing the first support base 13 and the second support base 14, in the transport state of the drilling device, the first support base 13 and the second support base 14 can simultaneously contact the upper part of the transport vehicle, facilitating limiting and fixing. At the same time, the first support base 13 can restrict the upper part of the first support 111 from moving upward, and the second support base 14 can restrict the upper part of the second support 112 from moving downward, avoiding unexpected changes in the transport state of the first support 111 due to possible depressurization of the rotating cylinder 42.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
