Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment technology, and more specifically to a small drilling rig used for small-scale drilling operations. Background Technology

[0002] In infrastructure construction projects such as highways and railways (e.g., tunnel construction during subway construction), it is often necessary to carry out small-scale drilling operations on the surface of mountains, inside mountains, or underground (e.g., the construction of anchor bolt holes and blasting holes). Such operations usually rely on small drilling rigs.

[0003] In the prior art, small drilling rigs used for the above-mentioned drilling operations typically include a base and a drilling device; the base is used to provide a supporting foundation for the drilling rig, and the drilling device is mounted on the base, which includes a drilling device (such as a rock drill) and a propulsion device, wherein the drilling device is used to perform specific drilling operations, and the propulsion device is used to drive the drilling device to move along a preset direction to achieve a feeding action.

[0004] However, in actual construction, the mountain surface or work platform often has a large number of uneven rocks or irregular structures, which often causes the drilling equipment to be placed at an angle, making it impossible to accurately drill at the predetermined position. Additional processing of the drilling rig's placement surface is necessary to meet the angle requirements of the drilling equipment, thus increasing construction procedures and labor costs, and reducing overall construction efficiency. Therefore, an adjustment base structure is needed to mount the drilling equipment on the base and allow for adjustment of the drilling equipment's installation angle. Utility Model Content

[0005] One of the purposes of this utility model is to address the shortcomings of the existing technology by providing an adjusting seat that can be mounted on a base to accommodate drilling devices that can be rotated to different angles and positions, adapting to different working conditions.

[0006] The second objective of this utility model is to provide a drilling machine that uses the above-mentioned adjusting seat to install the drilling device at an adjustable angle on the base, thereby improving construction efficiency under different working conditions.

[0007] The overall technical solution of this utility model is as follows:

[0008] This invention addresses the problem that existing drilling rigs cannot adjust the drilling angle to suit the actual environment, thus reducing construction efficiency. Specifically, existing drilling devices are often fixedly connected to the base in a non-adjustable manner. This means that when the platform is uneven, a significant amount of manpower and time must be spent modifying the platform, further reducing construction efficiency.

[0009] Based on this, the present invention proposes an adjusting seat for mounting a drilling device on a base and for mounting the drilling device to different angles under different operating conditions; the adjusting seat allows the drilling device to be mounted on the base at an adjustable angle.

[0010] Specifically, the adjusting seat in this utility model is used to form a mounting structure for the drilling device on the base, and the adjusting seat includes:

[0011] The mounting frame has a fixing part for fixedly connecting to the base;

[0012] A rotating shaft is rotatably mounted on the mounting frame, and a connecting plate for mounting the drilling device is provided at one end.

[0013] The control shaft is rotated and mounted on the mounting frame.

[0014] The axis of the rotating shaft and the axis of the control shaft are arranged in an alternating manner, and a transmission gear is fixedly mounted on the rotating shaft. The control shaft has helical teeth that extend spirally along the axial direction. The transmission gear and the helical teeth mesh to form a worm gear reducer structure.

[0015] One end of the control shaft also has a wheel that drives the control shaft to rotate;

[0016] The wheel has a handle, which is configured to be held by hand and to bear the force that drives the wheel to rotate.

[0017] The above solution provides an adjustment seat for mounting the drilling device on the base. When the drilling device is mounted on the base using this adjustment seat, the connecting plate is rotated by rotating the wheel, which can adapt to the installation of drilling devices at different tilt angles and under different drilling angle requirements. No additional modifications to the external environment are required, thus improving construction efficiency in different environments.

[0018] Furthermore, by employing a worm gear reducer structure to amplify the rotational torque input from the wheel disc, a larger torque can be obtained to drive the connecting plate on which the drilling device is mounted. Even if the drilling device is mounted on the connecting plate, the operator can more easily and effortlessly adjust the rotation angle of the connecting plate, thereby driving the drilling device to rotate and adjust the drilling angle.

[0019] In some embodiments, the handle is a column protruding on the side of the wheel facing away from the helical teeth;

[0020] Furthermore, the handle and the control shaft are arranged at intervals along the radial direction of the control shaft. This makes it easier for the operator to drive the wheel by gripping the handle.

[0021] In some embodiments, the handle portion has a first end connected to the wheel and a second end located away from the wheel;

[0022] The outer diameter of the handle gradually increases from the first end to the second end. This design better matches the force applied by the operator when gripping the handle, reducing the possibility of slipping out and improving the stability of force application during rotation.

[0023] In some embodiments, the outer surface of the control shaft has outwardly protruding teeth;

[0024] The mounting frame is connected to a rotatable locking rod, the rotation coverage area of ​​which overlaps with the rotation coverage area of ​​the locking teeth, so that the locking rod can rotate to collide with the locking teeth.

[0025] Furthermore, the locking rod is provided with a locking groove that matches the rotation trajectory of the locking tooth, allowing the locking tooth to engage.

[0026] By rotating the locking lever, the locking teeth are engaged / disengaged from the locking groove, so that the control shaft is in a non-rotatable locked state / rotatable movable state.

[0027] The locking mechanism, consisting of a locking rod and locking teeth, allows for the adjustment of the rotatability of the control shaft and connecting plate as needed. This enables the connecting plate to adapt to the tilt angle of the drilling device when adjustment is required, facilitating installation of the drilling device at that tilt angle. Conversely, when no adjustment is needed, the connecting plate provides stable support for the drilling device, enabling it to perform drilling operations more stably and effectively.

[0028] Furthermore, in some embodiments, the outer surface of the control shaft has a plurality of teeth spaced apart in the circumferential direction of the control shaft;

[0029] At least two locking slots are provided to allow the locking rod to engage with at least two locking teeth. By increasing the number of locking teeth, more engagement positions can be created on the control shaft. When locking the control shaft or connecting plate is required, a locking tooth can be engaged with the nearest locking slot more quickly to achieve locking. Furthermore, at least two locking slots are simultaneously provided on the locking rod to allow the locking teeth to engage with the locking rod at the same time, further improving the stability of the locking engagement.

[0030] Furthermore, in some embodiments, the locking rod is provided with a positioning hole, and the mounting frame is provided with a plug-in hole. When the control shaft is in the locked state, the plug-in hole and the positioning hole are aligned.

[0031] A movable pin is inserted into the positioning hole. The pin is configured such that when the insertion hole and the positioning hole are aligned, one end of the pin can be inserted into the insertion hole / pulled out of the insertion hole, so that the locking rod is in a non-rotatable locked state / rotatable movable state.

[0032] The detachable pin connection structure formed by the pin can further change the rotation state of the locking rod, so that when the control shaft is in a non-rotatable locked state, the locking rod is simultaneously made to be in a non-rotatable locked state, which can more stably ensure the locking and fixing of the control shaft.

[0033] Furthermore, in some embodiments, the positioning hole is a strip-shaped hole;

[0034] Furthermore, the positioning hole is configured such that, when the locking lever is in the locked state, the positioning hole extends in the direction of the interval between the axis of the pin and the axis of rotation of the locking lever. The positioning hole, with its strip-shaped hole structure, provides more movement space for the pin insertion, reducing the possibility that the pin may not be able to be properly inserted into the insertion hole due to production deviations.

[0035] This utility model also provides a drilling machine with the above-mentioned adjusting seat. Specifically, the drilling machine includes: a base, a drilling device, and the adjusting seat described in any of the above embodiments.

[0036] The fixing part of the adjusting seat is fixed to the base;

[0037] The drilling device is fixed to the connecting plate of the adjusting seat so that the drilling angle of the drilling device can be changed by rotating with the connecting plate.

[0038] When the placement angle of the drilling device cannot meet the drilling operation requirements, force is applied to the handle to drive the control shaft to rotate, which in turn drives the connecting plate to rotate. This allows the drilling device to be rotated to match the required drilling angle without requiring additional modifications to the external space, thereby improving the construction efficiency when using the drilling machine for drilling operations.

[0039] In some implementations, the control axis is configured to extend vertically;

[0040] Furthermore, the axis of rotation of the control shaft relative to the mounting bracket is also vertically arranged. In this way, when force is applied to the handle to drive the control shaft to rotate, this force and the weight of the control shaft itself are less likely to cause bending of the control shaft, thus better improving the service life of the control shaft.

[0041] Furthermore, in some embodiments, the wheel is positioned at the lower end of the control shaft, and at least part of the wheel is located below the mounting frame. This allows the mounting frame to provide some protection for the wheel, better preventing falling rocks during drilling from obstructing its rotation and thus improving the service life of the drilling rig.

[0042] The main beneficial effects of the above technical solution are as follows:

[0043] An adjustment base is provided for mounting the drilling device on the base and for adjusting the installation angle of the drilling device. It can be adapted to the installation of drilling devices at different angle positions to meet the drilling angle requirements under different working conditions.

[0044] It also provides a drilling machine that uses the aforementioned adjustment seat to mount the drilling device on the base, which can drive the drilling device to rotate to adapt to the drilling operation angle required in the actual environment without additional modification to the external space, thereby improving the construction efficiency when using the drilling machine for drilling operations.

[0050] Figure 5 A schematic diagram of the adjusting seat when the control shaft is in the locked position. Detailed Implementation

[0051] The present invention will be illustrated with specific examples below:

[0052] Example 1:

[0053] Adjustment seat 2, used to form a mounting structure for drilling device 3 on base 1, i.e.: as shown in the attached figure. Figure 1 As shown, the adjusting seat 2 is used to connect to the base 1 so that the base 1 has an installation structure for the drilling device 3 to be installed, so that the drilling device 3 can be installed on the base 1 through the adjusting seat 2.

[0054] For details, see attached. Figure 2 To be continued Figure 5As shown, the adjusting seat 2 includes a mounting frame 2.1 formed by several plates and rods. The mounting frame 2.1 has a fixing part 2.11 for fixing the mounting frame 2.1 to the base 1. For example, when the adjusting seat 2 is fixed to the base 1 with screws, the fixing part 2.11 can be a threaded hole through which the screw passes. The threaded end of the screw can pass through the fixing part 2.11 and be screwed to the base 1 to fix the mounting frame 2.1 to the base 1.

[0055] The mounting frame 2.1 has a rotatable shaft 2.2 inside, which is rotatably connected to the mounting frame 2.1 by means of, for example, a bearing. One end of the shaft 2.2 has a portion extending outside the mounting frame 2.1, and this portion is fixedly connected to a connecting plate 2.3 that rotates synchronously with the shaft 2.2. The connecting plate 2.3 is used for mounting the drilling device 3.

[0056] At this time, the connecting plate 2.3 may also have a protrusion that protrudes towards the mounting frame 2.1. The mounting frame 2.1 may be provided with a groove for the protrusion to be inserted when the connecting plate 2.3 rotates with the rotating shaft 2.2, so that the mounting frame 2.1 can directly support the rotatable connecting plate 2.3.

[0057] The mounting frame 2.1 is also equipped with a rotatable control shaft 2.4, which is rotatably connected to the mounting frame 2.1 by means of, for example, a bearing.

[0058] Furthermore, as attached Figure 2 As shown, the axis of the rotating shaft 2.2 and the axis of the control shaft 2.4 are arranged in an alternating manner. For example, the axis of the rotating shaft 2.2 is arranged horizontally, while the axis of the control shaft 2.4 is arranged vertically. A transmission gear 2.5 is fixedly mounted on the rotating shaft 2.2 and placed inside the mounting frame 2.1. The portion of the control shaft 2.4 placed inside the mounting frame 2.1 is provided with helical teeth 2.41 that extend helically along the axial direction.

[0059] The teeth of the transmission gear 2.5 and the helical teeth 2.41 mesh to form a worm gear reducer structure. At this time, by inputting torque A to drive the control shaft 2.4 to rotate, a torque B greater than torque A can be obtained to drive the rotating shaft 2.2 and the connecting plate 2.3 to rotate; the number of teeth of the transmission gear 2.5 and the helical teeth 2.41 are set according to the actual transmission ratio requirements.

[0060] The control shaft 2.4 has one end extending outward from the mounting bracket 2.1. This end also has a wheel 2.6 that drives the control shaft 2.4 to rotate. The wheel 2.6 has a handle 2.61, which is configured to be held by hand to bear the force that drives the wheel 2.6 to rotate. This allows the operator to hold the handle 2.61 and apply force to drive the wheel 2.6 to rotate, thereby driving the control shaft 2.4 to rotate.

[0061] As attached Figure 2 As shown, the handle portion 2.61 is a column protruding on the side of the wheel 2.6 facing away from the helical teeth 2.41. Furthermore, the handle portion 2.61 and the control shaft 2.4 are arranged at intervals in the radial direction of the control shaft 2.4; for example, when the axial direction of the control shaft 2.4 extends vertically, the handle portion 2.61 and the control shaft 2.4 are arranged at intervals in the horizontal direction.

[0062] The handle 2.61 can be detachably fixed to the wheel 2.6 by means of, for example, screws; the wheel 2.6 can also be detachably fixed to one end of the control shaft 2.4 by means of, for example, screws.

[0063] The handle portion 2.61 has a first end connected to the wheel 2.6 and a second end away from the wheel 2.6; the outer diameter of the handle portion 2.61 gradually increases in the direction from the first end to the second end, so that an inclined surface is formed on the surface of the handle portion 2.61 to prevent the hand holding the handle portion 2.61 from leaving the handle portion 2.61.

[0064] As attached Figure 4 Appendix Figure 5 As shown, the outer surface of the control shaft 2.4 has an outwardly protruding retaining tooth 2.42; the retaining tooth 2.42 is located on the side of the helical tooth 2.41 facing away from the wheel 2.6.

[0065] The mounting frame 2.1 is provided with a connecting shaft 2.13, and a locking rod 2.7 that can pivot relative to the connecting shaft 2.13 is pivotally connected to the connecting shaft 2.13. The rotation coverage area of ​​the locking rod 2.7 (the area that the object can pass through when it rotates) has a portion that overlaps with the rotation coverage area of ​​the locking tooth 2.42, so that when the locking rod 2.7 rotates, it can rotate to collide with the locking tooth 2.42.

[0066] Furthermore, the locking rod 2.7 is provided with a locking groove 2.71, which is set to match the rotation trajectory of the locking tooth 2.42 so that when the locking rod 2.7 rotates to the point of colliding with the locking tooth 2.42, the locking tooth 2.42 can engage in the locking groove 2.71 to lock the control shaft 2.4 and prevent the control shaft 2.4 from continuing to rotate.

[0067] At this point, by rotating the locking rod 2.7 in the forward direction, the locking teeth 2.42 are engaged in the locking groove 2.71, which makes the control shaft 2.4 in a non-rotatable locked state.

[0068] By rotating the locking rod 2.7 in the opposite direction, the locking teeth 2.42 are disengaged from the locking groove 2.71, allowing the control shaft 2.4 to be in a rotatable state.

[0069] The locking tooth 2.42 can be located in the part of the control shaft 2.4 that extends out of the mounting frame 2.1, or in the part located inside the mounting frame 2.1. In this case, as shown in the attached diagram... Figure 5 As shown, the mounting frame 2.1 may be provided with a notch 2.14 for the locking teeth 2.42 to engage with the locking rod 2.7.

[0070] The outer surface of the control shaft 2.4 may have a plurality of locking teeth 2.42 arranged at intervals around the circumference of the control shaft 2.4. Furthermore, at least two locking grooves 2.71 are provided so that when the locking rod 2.7 rotates to collide with the locking teeth 2.42, the locking rod 2.7 can engage at least two locking teeth 2.42.

[0071] As attached Figure 5 As shown, the locking rod 2.7 is provided with a positioning hole 2.72, and the mounting frame 2.1 is provided with a plug hole 2.12. When the control shaft 2.4 is in the locked state, the plug hole 2.12 and the positioning hole 2.72 are aligned.

[0072] A movable pin 2.8 is inserted into the positioning hole 2.72. The pin 2.8 is configured such that when the insertion hole 2.12 is aligned with the positioning hole 2.72, one end of the pin can be inserted into or removed from the insertion hole 2.12.

[0073] When one end of the pin 2.8 is inserted into the insertion hole 2.12, the locking rod 2.7 is locked in a non-rotatable state.

[0074] When one end of the pin 2.8 is pulled out of the insertion hole 2.12, the locking rod 2.7 is in a rotatable state.

[0075] The positioning hole 2.72 is preferably a strip-shaped hole, and the positioning hole 2.72 is configured such that when the locking rod 2.7 is in the locked state, the positioning hole 2.72 extends in the direction of the interval between the axis of the pin 2.8 and the axis of rotation of the locking rod 2.7.

[0076] When using adjustment seat 2:

[0077] The mounting frame 2.1 of the adjusting seat 2 is fixedly connected to the base 1 by the fixing part 2.11, while the drilling device 3 is fixedly connected to the connecting plate 2.3.

[0078] When it is necessary to adjust the drilling angle of the drilling device 3 according to the actual working conditions, the end of the pin 2.8 is pulled out from the insertion hole 2.12, and then the locking rod 2.7 is driven to rotate away from the control shaft 2.4 to disengage the locking tooth 2.42 from the locking groove 2.71 of the locking rod 2.7, so that the control shaft 2.4 is in a rotatable state.

[0079] At this time, by holding the handle 2.61 to drive the wheel 2.6 to rotate, the rotating shaft 2.2 and the connecting plate 2.3 can be driven to rotate, thereby causing the drilling device 3 to rotate to the tilt angle position that meets the drilling requirements.

[0080] After the angle is adjusted, the locking rod 2.7 is driven to rotate close to the control shaft 2.4 to engage the locking teeth 2.42 in the locking groove 2.71 of the locking rod 2.7. When the end of the pin 2.8 is inserted into the insertion hole 2.12, the position of the locking rod 2.7 and the control shaft 2.4 is locked, thereby locking the angle of the connecting plate 2.3 and the drilling device 3 and completing the angle adjustment.

[0081] Alternatively, the drilling device 3 can be installed on the connecting plate 2.3 without first adjusting the angle of the connecting plate 2.3 using the steps described above.

[0082] Example 2:

[0083] Drilling rig, as attached Figure 1 As shown, it includes: a base 1, a drilling device 3, and an adjustment seat 2 as described in any of the embodiments in Example 1.

[0084] The fixing part 2.11 of the adjusting seat 2 is fixed to the mounting bracket 1.1 of the base 1 by means of, for example, screws, and the drilling device 3 is fixed to the connecting plate 2.3 of the adjusting seat 2 by means of, for example, screws, so that the drilling device 3 can change the drilling angle of the drilling device 3 by rotating with the connecting plate 2.3.

[0085] The base 1 is a frame consisting of several rods and plates, which is used to provide support.

[0086] The drilling device 3 includes a propulsion beam 3.1 and a drilling device 3.2 (e.g., a rock drill); the propulsion beam 3.1 includes a propulsion beam housing and a propulsion device, the drilling device 3.2 is slidably mounted on the propulsion beam housing by, for example, a commonly used slide rail structure, and the propulsion device is connected to the drilling device 3.2 and drives the drilling device 3.2 to reciprocate on the propulsion beam housing.

[0087] During installation, the propulsion beam housing is fixed to the connecting plate 2.3 of the adjusting seat 2 by means of screws, for example. The propulsion device and the drilling device 3.2 are both installed on the propulsion beam housing.

[0088] The propulsion device can be a push rod motor, a hydraulic push rod device, or a screw drive structure, which has a part that can reciprocate. The drilling device 3.2 is fixedly connected to this part so that it can perform drilling operations by reciprocating under the drive of the propulsion device.

[0089] As attached Figure 2 To be continued Figure 3 As shown, the control shaft 2.4 is configured to extend vertically, meaning it is a vertical axis extending axially; the rotation shaft 2.2 is configured to extend horizontally, meaning it is a horizontal axis extending axially. In this case, the axis through which the control shaft 2.4 rotates relative to the mounting frame 2.1 is also vertically arranged.

[0090] The wheel 2.6 is positioned at the lower end of the control shaft 2.4, and at least part of the wheel 2.6 is located below the mounting frame 2.1, so that the mounting frame 2.1 covers the wheel 2.6 from above.

[0091] When it is necessary to adjust the drilling angle of the drilling device 3:

[0092] Pull the end of the pin 2.8 out of the insertion hole 2.12, and then drive the locking rod 2.7 away from the control shaft 2.4 to rotate, so as to disengage the locking tooth 2.42 from the locking groove 2.71 of the locking rod 2.7, so that the control shaft 2.4 is in a rotatable state.

[0093] At this time, by holding the handle 2.61 to drive the wheel 2.6 to rotate, the rotating shaft 2.2 and the connecting plate 2.3 can be driven to rotate, thereby causing the drilling device 3 to rotate to the tilt angle position that meets the drilling requirements.

[0094] After the angle is adjusted, the locking rod 2.7 is driven to rotate close to the control shaft 2.4 to engage the locking teeth 2.42 in the locking groove 2.71 of the locking rod 2.7. When the end of the pin 2.8 is inserted into the insertion hole 2.12, the position of the locking rod 2.7 and the control shaft 2.4 is locked, thereby locking the angle of the connecting plate 2.3 and the drilling device 3 and completing the angle adjustment.

Furthermore, the terms "vertical," "horizontal," "front," and "rear," etc., mentioned in the embodiments of the present utility model, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the product is in use.
