Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a lifting platform type drilling machine. Background Technology

[0002] Rock drilling rigs are large-scale construction equipment used for drilling blast holes, advance exploration holes, anchor bolt holes, and advance pipe roof holes. Traditional rock drilling rigs have insufficient drilling height due to the limitations of the boom, making it impossible to perform high-level drilling operations in large-section tunnels. Increasing the drilling height requires the use of multi-stage telescopic booms, which increases the overall size and weight of the machine and raises costs. In addition, there are problems such as difficulty and danger in adding and removing drill rods during high-level drilling, the need to frequently change the drilling position, and the need to constantly adjust the boom posture and telescopic stroke.

[0003] Therefore, it is necessary to provide a new type of lifting platform drilling rig to solve the above-mentioned technical problems. Utility Model Content

[0029] This utility model proposes a lifting platform type drilling rig, which aims to solve the problems of existing drilling equipment requiring frequent changes in drilling positions and low working efficiency.

[0030] See Figure 1The lifting platform drilling rig includes a traveling chassis 1, a lifting platform mechanism 2, a drilling device 3, and a lateral drive mechanism. The traveling chassis 1 can travel along the ground. The lifting platform mechanism 2 is mounted on the traveling chassis 1 and can be raised and lowered in the vertical direction. The drilling device 3 is slidably mounted on the lifting platform mechanism 2 and is used for drilling operations. The lateral drive mechanism is located between the drilling device 3 and the lifting platform mechanism 2 and can drive the drilling device 3 to slide along the lifting platform mechanism 2. In this embodiment, the lifting platform drilling rig travels along the ground via the traveling chassis 1. The lifting platform mechanism 2 can raise the drilling device 3 to any height to adapt to drilling operations at different heights. Furthermore, the lateral movement mechanism can drive the drilling device 3 to move along the width of the traveling chassis 1 to adapt to drilling operations at different horizontal positions. This satisfies the need for large-scale drilling operations in the vertical direction, improves the adaptability of the step method, reduces the attitude adjustment movements of the drilling device 3, and allows operators to add and remove drill rods on the lifting platform mechanism 2, reducing the workload of manually carrying drill rods up and down ladders and increasing the safety of installing and removing drill rods. Compared to traditional rock drilling rigs with their pitch cylinders, telescopic cylinders, and multi-stage telescopic booms, which have complex manufacturing processes and higher costs, and require regular maintenance and replacement of the internal sliders of multi-stage telescopic booms, resulting in poor maintainability, the lifting platform drilling rig is simpler to design, manufacture, and process, is more cost-effective, and offers better maintainability.

[0031] See also Figure 2 and Figure 3 The lifting platform mechanism 2 includes a scissor lift structure 2.1, a work platform 2.2, and a lifting drive mechanism 2.3. The scissor lift structure 2.1 is mounted on the chassis 1; the work platform 2.2 is mounted on the scissor lift structure 2.1; the lifting drive mechanism 2.3 connects the hinge point of the scissor lift structure 2.1 to the chassis 1. The lifting drive mechanism 2.3 can change the position of the hinge point of the scissor lift structure 2.1 to drive the work platform 2.2 to rise and fall. By changing the position of the hinge point of the scissor lift structure 2.1, the lifting drive mechanism 2.3 drives the scissor lift structure 2.1 to extend or retract, thereby adjusting the height of the work platform 2.2 on the scissor lift structure 2.1. The operation is simple and the adjustment is convenient.

[0032] The workbench 2.2 includes a main board 2.2.1 and two hinged flaps 2.2.2 at both ends of the main board 2.2.1. The main board 2.2.1 is mounted on the scissor structure 2.1. The lifting platform mechanism 2 also includes a flip drive assembly 2.4, which includes a mounting plate 2.4.1 and two flip drive components 2.4.2. The mounting plate 2.4.1 is vertically mounted on the bottom of the main board 2.2.1. The flip drive components 2.4.2 are correspondingly mounted to the flaps 2.2.2. The first end of the flip drive component 2.4.2 is hinged to the end of the mounting plate 2.4.1 away from the main board 2.2.1, and the second end is hinged to the corresponding flap 2.2.2. The flip drive component 2.4.2 can drive the flaps 2.2.2 to move between horizontal and vertical positions. When the flip plate 2.2.2 is in a horizontal position, it is on the same plane as the main board 2.2.1. The drilling device 3 can move on the main board 2.2.1 and the flip plate 2.2.2 under the action of the lateral drive mechanism to meet the drilling construction needs at different positions in the horizontal direction. After the drilling device 3 is moved onto the flip plate 2.2.2, the flip plate 2.2.2 is driven by the flip plate 2.2.2 drive assembly to flip the flip plate 2.2.2 from the horizontal position to the vertical position. At this time, the flip plate 2.2.2 is set perpendicular to the main board 2.2.1, so that the drilling device 3 can adapt to a wide range of pitch drilling conditions in the vertical direction, meeting the needs of various working conditions and effectively reducing the attitude adjustment movements of the drilling device 3. The lifting platform mechanism 2 can be adjusted according to different needs, such as increasing the platform height and changing the shape of the worktable, so as to adapt to small and medium-sized tunnels and large-section tunnels. This flexibility allows the lifting platform drilling rig to adapt to various complex drilling working conditions, improving the flexibility and adaptability of the operation.

[0033] Specifically, the lifting platform mechanism 2 also includes two slide rails 2.5 arranged along the width direction of the traveling chassis 1. The two slide rails 2.5 are arranged opposite to each other. Each slide rail 2.5 includes a first section 2.5.1, a second section 2.5.2, and a third section 2.5.3 arranged along the same straight direction and abutting each other in sequence. The first section 2.5.1 and the second section 2.5.2 are respectively arranged on two flip plates 2.2.2, and the second section 2.5.2 is arranged on the main plate 2.2.1. The drilling device 3 is slidably connected to the two slide rails 2.5 respectively. The transverse drive mechanism includes a transverse drive component, a gear, and a rack. The transverse drive component is arranged on the drilling device 3. The gear is connected to the output shaft of the transverse drive component. The rack is arranged on the slide rail 2.5 along the width direction of the traveling chassis 1, and the gear meshes with the rack. The transverse drive component can drive the gear to move along the rack, so as to drive the drilling device 3 to move along the slide rail 2.5. When the flap 2.2.2 is in the horizontal position, the first section 2.5.1, the second section 2.5.2, and the third section 2.5.3 of the slide rail 2.5 abut together in sequence to form a continuous overall structure. The lateral drive can drive the gear to move along the rack on the slide rail 2.5, thereby driving the slide plate 3.2 to slide along the slide rail 2.5, which in turn enables the drilling device 3 to move laterally on the worktable 2.2, further expanding the working range of the drilling device 3.

[0034] In this embodiment, the scissor lift structure 2.1 includes two scissor lift support members 2.1.1 spaced apart along the width direction of the chassis 1. Each scissor lift support member 2.1.1 includes two cross-hinged support rods A1. The first end of one support rod A1 is hinged to the main board 2.2.1, and the second end of one support rod A1 is hinged to the chassis 1. The second end of the other support rod A1 is slidably hinged to the chassis 1 along its length. A lifting drive mechanism 2.3 is disposed between the two scissor lift support members 2.1.1. The two support rods A1 in the scissor lift structure 2.1 are hinged to each other. Under the action of the lifting drive mechanism 2.3, the two support rods A1 move closer or further apart to drive the main board 2.2.1 to lift. The two scissor lift support members 2.1.1 cooperate to support the main board 2.2.1, which helps ensure the stability of the lifting process.

[0035] Furthermore, the lifting drive mechanism 2.3 includes a crossbeam 2.3.1 and a lifting drive component 2.3.2. The crossbeam 2.3.1 includes a crossbar B1 and a lug B2. The crossbar B1 is connected between the hinge points of two parallel support rods A1. The lug B2 is vertically mounted on the crossbar B1, and the end of the lug B2 away from the crossbar B1 forms an extension, which is inclined in the vertical direction. The lifting drive component 2.3.2 is hinged between the extension and the traveling chassis 1. The lifting drive component 2.3.2 drives the crossbar B1 through the extension to rotate the two parallel support rods A1, thereby raising or lowering the hinge points of the two scissor structures 2.1, causing the two scissor structures 2.1 to extend or fold. The extension is inclined to convert the force applied by the lifting drive component 2.3.2 into the force that drives the support rods A1 to rotate through the lug B2 via the crossbar B1, ensuring transmission stability while achieving simultaneous lifting and lowering.

[0036] Furthermore, the number of lifting drive components 2.3.2 is one or more, with each lifting drive component 2.3.2 spaced apart along the width direction of the traveling chassis 1, and each lifting drive component 2.3.2 corresponding to an ear seat B2. Each lifting drive component 2.3.2 works in conjunction with the crossbeam 2.3.1 to drive the support rod A1 to rotate, which helps to improve operational stability and efficiency.

[0037] In this embodiment, there are two lateral movement drive mechanisms, which cooperate to drive the drilling device 3 to move along the slide rail 2.5. The two lateral movement drive mechanisms drive synchronously, and both slide rails 2.5 are equipped with racks. The gears in the two lateral movement drive mechanisms rotate in opposite directions to cooperate in driving the drilling device 3 to move in a specified direction, which improves the stability of the lateral movement process and helps to ensure operational safety.

[0038] Specifically, the main board 2.2.1 is equipped with evenly spaced anti-slip protrusions, and both sides of the main board 2.2.1 along its width are equipped with flip-up guardrails 2.2.3. Operators can connect and disconnect drill rods on the main board 2.2.1, increasing the safety and convenience of connecting and disconnecting rods when drilling at high positions. The anti-slip protrusions effectively prevent slippage and improve operational safety.

[0039] See Figure 4The drilling device 3 includes a rotary drive 3.1, a sliding plate 3.2, a rotary seat 3.3, a propulsion beam 3.4, a propulsion compensation drive 3.5, a power head 3.6, and a clamp 3.7. The rotary drive 3.1 is slidably connected to the lifting platform mechanism 2 via the sliding plate 3.2; the rotary seat 3.3 is connected to the output end of the rotary drive 3.1; the propulsion beam 3.4 is slidably mounted on the rotary seat 3.3; the propulsion compensation drive 3.5 is connected between the rotary seat 3.3 and the propulsion beam 3.4, and can drive the propulsion beam 3.4 to slide relative to the rotary seat 3.3; the power head 3.6 is mounted on the propulsion beam 3.4 for drilling operations; and the clamp 3.7 is mounted on the propulsion beam 3.4 for limiting the drill rod position. In this embodiment, the rotary drive 3.1 is a rotary reducer. The propulsion beam 3.4 achieves 360° rotation through the rotary reducer at the bottom. At the same time, the propulsion compensation drive 3.5 extends the propulsion beam 3.4 to the top of the rock surface, realizing drilling at any angle in the horizontal direction. This not only meets the drilling conditions of the front face, but also enables the construction of multi-angle working conditions such as tunnel sidewall exploration holes and drainage holes.

[0040] In addition, the lifting platform drilling rig also includes a hydraulic oil tank 4, a motor pump unit 5, an electrical system 6, and an engine system 7. The hydraulic oil tank 4 stores hydraulic oil; the motor pump unit 5 is located on the oil line between the hydraulic oil tank 4 and the drilling device 3, and is used to provide power to the drilling device 3; the electrical system 6 is used to control the drilling device 3 to perform drilling operations; and the engine system 7 is used to drive the traveling chassis 1 to move along the ground. The motor pump unit 5 provides power for all the actions of the drilling rig, the hydraulic oil tank 4 stores hydraulic oil, and the electrical system 6 contains switches to control the electrical equipment in the drilling rig. The equipment uses engine power when moving and transferring, and uses electric motor power when drilling in tunnels, thus avoiding exhaust gas pollution in the confined space of the tunnel.
