[0007] Optionally, the running wheels include swivel casters and fixed casters, with a pair of swivel casters mounted at one end of the chassis body along the longitudinal direction and a pair of fixed casters mounted at the other end of the chassis body along the longitudinal direction.

[0008] Optionally, it also includes a lifting cylinder, which is vertically mounted on the chassis body.

[0009] Optionally, it also includes a hydraulic column, which is vertically mounted on the chassis body.

[0010] Optionally, the chassis further includes a clamp assembly, which includes a first clamp plate and a second clamp plate. The second clamp plate is fixedly connected to the chassis body, and the first clamp plate is used to connect with the second clamp plate to form a ring structure for sleeve connection to the hydraulic column.

[0011] Optionally, the chassis body includes crossbeams and supporting longitudinal beams. The two crossbeams are arranged parallel to each other in the transverse direction, and the two supporting longitudinal beams are arranged parallel to each other in the longitudinal direction.

[0022] It should be noted that in the XYZ coordinate system provided herein, the positive X-axis represents the right, and the negative X-axis represents the left; the positive Y-axis represents the rear, and the negative Y-axis represents the front; the positive Z-axis represents the top, and the negative Z-axis represents the bottom. Furthermore, it should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0023] This invention provides a drilling rig trolley, including a chassis 1, traveling wheels 2, and a drilling rig 3. The chassis 1 includes a chassis body 11 and a support plate 12 connected to each other. The support plate 12 has a first mounting hole 121 and a second mounting hole 122. At least two of the first mounting holes 121 are arranged in an arc-shaped interval with the central axis of the second mounting hole 122 as the central axis. The traveling wheels 2 are mounted on the chassis body 11. The drilling rig 3 includes a body 31, a connecting member 32, and a rotating connecting member 33. The connecting member 32 is connected to the body 31, and the rotating connecting member 33 is rotatably connected to the body 31 and connected to the support plate 12 in the second mounting hole 122. The body 31 is detachably connected to the support plate 12 in the first mounting hole 121 via the connecting member 32.

[0024] Specifically, in combination Figure 1 As shown, the support plate 12 is a flat plate structure, parallel to the ZY plane in the figure, and fixedly connected to the chassis body 11 (to ensure the stability of the connection between the drilling rig 3 and the body 31, multiple support plates 12 can be arranged parallel to each other on the chassis body 11 and connected to the body 31). The traveling wheels 2 can be selected from existing wheel sets as needed. Figure 2 and Figure 4 As shown, the support plate 12 has first mounting holes 121 and second mounting holes 122 on its surface (the example in the figure shows five first mounting holes 121; in actual applications, the design can be customized according to the drilling rig angle requirements). These five first mounting holes 121 are arranged in an arc shape with a certain radius around the central axis of the second mounting holes 122 (i.e., the axis on the second mounting hole 122 that passes through its own center and is parallel to the X-axis in the figure). The interval angle between each first mounting hole 121 is 8° (usually, the interval distance and angle between each first mounting hole 121 are equal, but different interval distances and angles can be designed according to the drilling rig angle requirements). Thus, the line connecting each first mounting hole 121 to the second mounting hole 122 has an inclination angle of 0°, ±8°, and ±16°, respectively. Combined with... Figure 1 As shown, the connector 32 can be a fastener such as a bolt, which passes through the first mounting hole 121 and the preset mounting hole on the body 31 to detachably connect the body 31 and the support plate 12. The rotating connector 33 can be a component in the prior art that can realize relative rotation between the two structures, such as a bearing or a hinge.

[0025] The drilling trolley of the present invention connects the drilling machine 3 to the support plate 12 and mounts the traveling wheels 2 on the chassis body 11, so that the drilling trolley can move the drilling machine 3. Furthermore, the support plate 12 is provided with a first mounting hole 121 and a second mounting hole 122. The drilling machine 3 can rotate around the second mounting hole 122 as the axis by rotating the connecting piece 33. Since the first mounting holes 121 are distributed in an arc shape with the central axis of the second mounting hole 122 as the axis, the drilling machine 3 can be detachably connected to the support plate 12 at each first mounting hole 121 by the connecting piece 32, thereby realizing the function of adjusting the drilling angle of the drilling machine 3. This allows the drilling trolley to be used in working conditions with various tunnel sizes, achieve more precise drilling operations, and improve the flexibility of the drilling trolley.

[0026] Optionally, the connector 32 includes a pin 321 and a cotter pin 322. The body 31 is detachably connected to the support plate 12 in the first mounting hole 121 via the pin 321. The cotter pin 322 is detachably connected to the pin 321 to limit the pin 321.

[0027] Specifically, in combination Figure 2 As shown, the pin 321 is provided with a through hole for inserting the cotter pin 322 (that is, a through hole arranged radially along the cylindrical pin 321 in the figure). The pin 321 is inserted into the first mounting hole 121 and the preset mounting hole on the body 31, and the cotter pin 322 is inserted into the aforementioned through hole.

[0028] Thus, the detachable connection between the machine body 31 and the support plate 12 can be achieved through the pin 321, and the disassembly and assembly process is relatively simple and quick; the cotter pin 322 is detachably connected to the pin 321, which plays a limiting role on the pin 321, preventing the pin 321 from coming out of the first mounting hole 121 along its own axis, thereby improving the safety of the drilling carriage.

[0029] Optionally, the rotating connector 33 includes a pin 331 and a baffle 332. The pin 331 has a groove, and the baffle 332 is mounted on the support plate 12 and abuts against the pin 331 in the groove. The pin 331 is rotatably connected to the machine body 31.

[0030] Specifically, in combination Figure 1 and Figure 2 As shown, the pin 331 is inserted into the second mounting hole 122 and rotatably connected to the body 31. The pin 331 has a groove at each end along the positive and negative directions of the Y-axis in the figure. Two rectangular plate-shaped baffles 332 are mounted on the support plate 12 by fasteners and are located on both sides of the pin 331 along the positive and negative directions of the Y-axis in the figure. The baffles 332 abut against the pin 331 in the grooves on the pin 331.

[0031] Thus, the rotation of the pin 331 relative to the support plate 12 is restricted by the baffle 332, so that the rotation between the pin 331 and the body 31 is more stable.

[0032] Optionally, the running wheels 2 include swivel casters 21 and directional casters 22. A pair of swivel casters 21 are installed at one end of the chassis body 11 along the longitudinal direction, and a pair of directional casters 22 are installed at the other end of the chassis body 11 along the longitudinal direction.

[0033] Specifically, in combination Figure 1 and Figure 3 As shown, the swivel caster 21 is mounted on the chassis body 11 at one end in the opposite direction of the Y-axis in the figure via its own mounting base, and the fixed caster 22 is mounted on the chassis body 11 at one end in the positive direction of the Y-axis in the figure via its own mounting base. The caster part of the swivel caster 21 can rotate relative to the mounting base part, while the angle of the fixed caster 22 remains unchanged.

[0034] Thus, the omnidirectional casters 21 and directional casters 22 enable the drilling trolley to move stably in all directions.

[0035] Optionally, it also includes a lifting cylinder 5, which is vertically mounted on the chassis body 11.

[0036] Specifically, in combination Figure 3As shown, the cylinder body of the lifting cylinder 5 is mounted on the lower end of the chassis body 11 (i.e., the end opposite to the Z-axis in the figure) via a connecting plate and fasteners, and the piston part of the lifting cylinder 5 faces the ground.

[0037] Thus, by controlling the extension and retraction of the lifting cylinder 5, the drilling rig 3 can be driven to move up and down, thereby adjusting the drilling position and improving the flexibility of the drilling trolley.

[0038] Optionally, combined Figure 3 As shown, it also includes a hydraulic column 4, which is vertically mounted on the chassis body 11. The piston portion of the hydraulic column 4 faces upward, and the cylinder portion is mounted on the chassis body 11. In this way, before drilling operations are carried out downhole, the hydraulic column 4 is extended so that its upper and lower ends press against the well wall to achieve stable drilling operations.

[0039] Optionally, the chassis 1 further includes a clamp assembly 13, which includes a first clamp plate 131 and a second clamp plate 132. The second clamp plate 132 is fixedly connected to the chassis body 11, and the first clamp plate 131 is used to connect with the second clamp plate 132 to form a ring structure for sleeve connection to the hydraulic column 4.

[0040] Specifically, in combination Figure 1 and Figure 4 As shown, the first hoop 131 and the second hoop 132 are both semi-circular arc hoop structures. The first hoop 131 and the second hoop 132 are connected by fasteners to form a ring structure similar to a sleeve (i.e., the clamp assembly 13), which is then fitted and connected to the hydraulic column 4.

[0041] Thus, the clamp assembly 13 can be fitted and connected to the hydraulic column 4. When the hydraulic column 4 extends and abuts against the well wall, the chassis body 11 achieves a stable connection with the hydraulic column 4 through the clamp assembly 13, ensuring the stability of the drilling trolley during drilling operations.

[0042] Optionally, the chassis body 11 includes a crossbeam 111 and a supporting longitudinal beam 112. The two crossbeams 111 are arranged parallel to each other in the transverse direction, and the two supporting longitudinal beams 112 are arranged parallel to each other in the longitudinal direction. One end of each of the two supporting longitudinal beams 112 is fixedly connected to one of the two crossbeams 111 in the longitudinal direction, and the other end is fixedly connected to the other crossbeam 111 in the longitudinal direction. The two supporting plates 12 are arranged vertically opposite to each other and are respectively fixedly connected to the two supporting longitudinal beams 112.

[0043] Specifically, in combination Figure 4As shown, two crossbeams 111 and two supporting longitudinal beams 112 are arranged in an I-shape. The two supporting longitudinal beams 112 are arranged parallel to the Y-axis in the figure, and the two crossbeams 111 are arranged parallel to the X-axis in the figure. The ends of the two supporting longitudinal beams 112 along the positive Y-axis in the figure are welded and fixed to one crossbeam 111, and the ends of the two supporting longitudinal beams 112 along the opposite Y-axis in the figure are welded and fixed to the other crossbeam 111. The surfaces of the two supporting plates 12 are parallel to the ZY plane in the figure and are respectively installed on the two supporting longitudinal beams 112.

[0044] In this way, the overall structure of the chassis body 11 of the drilling rig trolley is more stable. The support plate 12 is supported by two support longitudinal beams 112, and the drilling rig 3 is connected by the two support plates 12, which improves the accuracy of the drilling operation of the drilling rig 3.

[0045] Optionally, the chassis body 11 further includes an installation platform 113, which is horizontally arranged and located between the two crossbeams 111. The installation platform 113 is fixedly connected to the supporting longitudinal beam 112 and the two crossbeams 111, and the running wheels 2 are mounted on the installation platform 113.

[0046] Specifically, in combination Figure 3 and 4 As shown, the mounting platform 113 is a plate-like structure, fixedly installed on the lower end face of the supporting longitudinal beam 112 and transverse beam 111 by welding or fastener connection. The swivel casters 21 and directional casters 22 of the traveling wheels 2 are installed on the lower end face of the mounting platform 113 by mounting seats and fasteners. In addition, the mounting platform 113 has U-shaped openings at both ends along the X-axis direction in the figure. The cylinder body of the lifting cylinder 5 is located in the U-shaped opening, and the connecting plate of its cylinder body is installed on the mounting platform 113 by fasteners. In this way, the lifting cylinder 5 can better drive the entire drilling rig trolley to move up and down.

[0047] Thus, the structural design of the mounting platform 113 facilitates the installation of components such as the running wheels 2, while also improving the stability of the chassis body 11.

[0048] Optionally, combined Figure 4 As shown, the chassis body 11 also includes stiffening plates 114, which are fixedly connected to the mounting platform 113 and the support plate 12. Multiple stiffening plates 114 can be set as needed. In this embodiment, a single support plate 12 is equipped with two stiffening plates 114, and a total of four stiffening plates 114 are symmetrically arranged along the Y-axis in the figure.

[0049] This further strengthens the support plate 12, improving the stability of the drilling rig 3 and ensuring the accuracy of the drilling operation.

[0050] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
