Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and more specifically, to a rock drilling rig propulsion beam positioning mechanism and a rock drilling rig. Background Technology

[0002] In engineering fields such as tunnel excavation and mining, rock drills are core equipment for achieving efficient drilling operations. Their performance largely depends on the flexibility of the propulsion beam positioning mechanism—this mechanism needs to precisely control the spatial orientation of the drill bit to quickly cover blast holes at different locations on the working face. Currently, rock drills typically use multi-stage articulated arms in conjunction with an end-positioning mechanism to position the propulsion beam. The propulsion beam's own orientation adjustment capability directly affects the hole-laying efficiency and equipment mobility, resulting in the propulsion beam being unable to position blast holes at certain locations. Utility Model Content

[0003] This utility model provides a positioning mechanism for the propulsion beam of a rock drilling rig and a rock drilling rig, which improves the orientation adjustment capability of the propulsion beam and enables the blast hole at each position to be positioned.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A rock drilling rig's propulsion beam positioning mechanism includes a frame, a rocker arm, a swing arm, and a propulsion beam mounting bracket.

[0006] One end of the frame is rotatably connected to the base and can rotate around the base in the up-down direction, and the other end is rotatably connected to one end of the rocker arm, so that the rocker arm can rotate around the frame in the front-back direction; the rocker arm is also rotatably connected to one end of the swing arm, and the swing arm can swing around the rocker arm in the left-right direction; the other end of the swing arm is connected to the propulsion beam mounting frame through a rotary assembly, and the rotary assembly can drive the propulsion beam mounting frame to rotate at all angles in the left-right direction.

[0007] As a further improvement, the rotary assembly includes a rotary drive and a rotary output end of the drive. The rotary output end of the drive is connected to the propulsion beam mounting bracket, which is used to slidably connect the propulsion beam.

[0008] As a further improvement, the propulsion beam mounting bracket can be connected to the propulsion beam via a propulsion cylinder, which is used to propel the propulsion beam to move.

[0009] As a further improvement, the rotation drive has at least one component, and the rotation drive is a hydraulic motor; the rotation output end of the drive is a rotatable worm gear.

[0010] As a further improvement, the frame is connected to the base via a frame pivot, and a lifting cylinder is also connected between the frame and the base, the lifting cylinder being used to drive the frame to rotate.

[0011] As a further improvement, the rocker arm is connected to the frame via a rocker arm pivot, and a pitch cylinder is also connected between the rocker arm and the frame, the pitch cylinder being used to drive the rocker arm to rotate.

[0012] As a further improvement, the swing arm is connected to the rocker arm via a swing arm pivot, and at least one swing cylinder is also connected between the swing arm and the rocker arm, the swing cylinder being used to drive the swing arm to swing.

[0013] As a further improvement, two swing cylinders are provided, which are symmetrically arranged on the left and right sides of the swing arm.

[0014] As a further improvement, at least one support rod is also connected to the end of the frame away from the base.

[0015] This utility model also provides a rock drilling rig, including the rock drilling rig propulsion beam positioning mechanism, wherein the base is connected to the frame of the rock drilling rig.

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] (1) The rock drilling rig propulsion beam positioning mechanism of this utility model makes the structure simpler and more flexible by using the rocker arm, swing arm and propulsion beam mounting frame to move in different directions. The propulsion beam mounting frame can rotate in the full range of angles through the drive of the rotary component, that is, the propulsion beam mounting frame can rotate 360° to achieve 360° full coverage of the tunnel cross section for rock drilling.

[0018] (2) The rock drilling rig propulsion beam positioning mechanism of this utility model has a hydraulic motor as the rotating drive component in the rotary assembly; the rotating output end of the drive component is a rotatable worm gear, which is small in size and more compact in structure, and has better weather resistance. It can reduce the maintenance frequency of the equipment when operating in underground mines with poor environment.

[0019] (3) The rock drilling rig propulsion beam positioning mechanism of this utility model has two swing cylinders, which makes the swing arm more stable when it swings.

[0020] (4) The positioning mechanism of the rock drilling rig propulsion beam of this utility model has at least one support rod connected to the end of the frame away from the base, which is used to support the positioning mechanism so that it is firmly in contact with the ground and can adjust the height difference between the left and right sides of the positioning mechanism and the ground so that both sides of the positioning mechanism can be firmly in contact with the ground, thereby compensating for the situation where the positioning mechanism is unstable due to uneven ground and cannot be firmly in contact with the ground.

[0038] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0039] like Figure 1-3 As shown, this embodiment provides a rock drilling rig propulsion beam positioning mechanism, including a frame 2, a rocker arm 3, a swing arm 4, and a propulsion beam mounting frame 501.

[0040] One end of the frame 2 is rotatably connected to the base 1 and can rotate around the base 1 in the up-down direction. The other end is rotatably connected to one end of the rocker arm 3, so that the rocker arm 3 can rotate around the frame 2 in the front-back direction. The rocker arm 3 is also rotatably connected to one end of the swing arm 4, which can swing around the rocker arm 3 in the left-right direction. The other end of the swing arm 4 is connected to the push beam 5 through the rotary assembly 405, which can drive the push beam mounting frame 501 to rotate at all angles in the left-right direction.

[0041] by Figure 1To explain, if the operator is on the rock drilling rig and facing the positioning mechanism of the propulsion beam, the forward and backward directions of the rock drilling rig are the "front and back directions", the left and right directions of the operator are the "left and right directions", and the up and down directions of the operator are the "up and down directions".

[0042] The rock drilling rig's propulsion beam positioning mechanism in this design achieves a simpler and more flexible structure through the movement of the rocker arm 3, swing arm 4, and propulsion beam mounting frame 501 in different directions. Driven by the rotary assembly 405, the propulsion beam mounting frame 501 can rotate within a full angular range, enabling 360° rotation and achieving 360° full coverage of the tunnel cross-section for rock drilling. Furthermore, the swing arm 4 and the rotary assembly 405 cooperate and compensate for each other, allowing for better parallel drilling operations.

[0043] like Figure 5 As shown, the rotary assembly 405 includes a rotation drive 4051 and a drive rotation output end 4052. The drive rotation output end 4052 is connected to the propulsion beam mounting bracket 501, which is used to slide with the propulsion beam 5.

[0044] Furthermore, combined Figure 9 and Figure 10 As shown, a propulsion cylinder 502 can be connected between the propulsion beam mounting frame 501 and the propulsion beam 5. The propulsion cylinder 502 is used to propel the propulsion beam 5. Specifically, the propulsion beam mounting frame 501 is fixedly connected to the drive component rotation output end 4052. When the drive component rotation output end 4052 rotates, it drives the propulsion beam mounting frame 501 to rotate. At the same time, one end of the propulsion cylinder 502 is connected to the propulsion beam mounting frame 501, and the other end is connected to the propulsion beam 5, which is used to drive the propulsion beam 5 to slide back and forth along the propulsion beam mounting frame 501.

[0045] In a preferred embodiment, the rotation drive 4051 has at least one component, and the rotation drive 4051 is a hydraulic motor; the rotation output end 4052 of the drive component is a rotatable worm gear. More specifically, as... Figure 5 As shown, the rotation drive component 4051 is connected to the brake 4053, the brake 4053 is connected to a worm gear, and the worm gear is connected to the rotation output end 4052 of the drive component, forming a worm gear reducer, which is used to drive the propulsion beam mounting frame 501 to rotate. In this embodiment, two rotation drive components 4051 are provided, respectively located on both sides of the rotation output end 4052 of the drive component. Using two rotation drive components 4051 increases the rotational torque of the rotation output end 4052 of the drive component, enabling it to carry a larger load.

[0046] Of course, in other embodiments, the rotation drive 4051 can also be a geared motor, and the rotation output end 4052 of the drive is the output shaft of the geared motor. However, in this embodiment, a hydraulic motor is used to drive the worm gear to rotate, thereby driving the propulsion beam mounting frame 501. This method results in a smaller size and more compact structure, as well as better weather resistance. When operating in harsh environments such as underground mines, it can reduce the frequency of equipment maintenance.

[0047] See Figure 6 As shown, frame 2 is connected to base 1 via frame pivot 201. Lifting cylinder 202 is also connected between frame 2 and base 1. Lifting cylinder 202 is used to drive frame 2 to rotate. One end of lifting cylinder 202 is connected to base 1, and the other end is connected to frame 2. Lifting cylinder 202 pushes frame 2 to rotate around frame pivot 201, causing frame 2 to rotate up and down.

[0048] See Figure 7 As shown, the end of frame 2 furthest from base 1 is connected to rocker arm 3. Specifically, rocker arm 3 is connected to frame 2 via rocker arm pivot 301, and a pitch cylinder 302 is also connected between rocker arm 3 and frame 2. Pitch cylinder 302 is used to drive rocker arm 3 to rotate. Specifically, one end of pitch cylinder 302 is pitch cylinder first connecting shaft 303, which is connected to frame 2; the other end of pitch cylinder 302 is pitch cylinder second connecting shaft 304, which is connected to the end of rocker arm 3 furthest from rocker arm pivot 301, so that pitch cylinder 302 can drive rocker arm 3 to rotate around rocker arm pivot 301.

[0049] Combination Figure 1 , Figure 7 and Figure 8 As shown, one end of the rocker arm 3 near the rocker arm pivot 301 is also connected to the swing arm 4. Specifically, the swing arm 4 is connected to the rocker arm 3 via the swing arm pivot 401, and at least one swing cylinder 402 is also connected between the swing arm 4 and the rocker arm 3. The swing cylinder 402 is used to drive the swing arm 4 to swing.

[0050] Preferably, two swing cylinders 402 are provided, symmetrically arranged on the left and right sides of the swing arm 4. Specifically, one end of the swing cylinder 402 is a first connecting shaft 403, connected to the rocker arm 3; the other end of the swing cylinder 402 is a second connecting shaft 404, connected to the end of the swing arm 4 away from the swing arm pivot 401. When the swing arm 4 swings, one swing cylinder 402 extends and the other swing cylinder 402 shortens, causing the swing arm 4 to rotate around the swing arm pivot 401. Providing two swing cylinders 402 gives the swing arm 4 better stability during swinging.

[0051] Combination Figure 1 and Figure 4As shown, regarding the rocker arm 3, it should also be noted that the front center of the rocker arm 3 has a receiving position for mounting the pitch cylinder 302. The rocker arm pivot 301 has two shafts located on both sides of the rocker arm 3 and simultaneously connected to the frame 2. The rocker arm 3 above the pivot 301 is also connected to the first connecting shaft 403 of the swing cylinder. The swing arm pivot 401 is mounted on the rear center of the rocker arm 3, and is connected to the swing arm 4. The rotation direction of the swing arm pivot 401 is perpendicular to that of the rocker arm pivot 301.

[0052] It should be noted that when frame 2 is raised up and down, the rocker arm 3, swing arm 4, and push beam 5 connected to it are raised simultaneously. When rocker arm 3 rotates back and forth, the swing arm 4 and push beam 5 connected to it rotate simultaneously. When swing arm 4 swings left and right, the push beam 5 connected to it swings simultaneously.

[0053] As a further improvement, at least one support rod 6 is connected to the end of the frame 2 furthest from the base 1. In a preferred embodiment, two support rods 6 are provided, located on the left and right sides of the frame 2 respectively. The support rods 6 are jacks used for support and are fixedly connected to the frame 2. The support rods 6 are used to support the positioning mechanism so that it is in firm contact with the ground, and can adjust the height difference between the left and right sides of the positioning mechanism and the ground, so that both sides of the positioning mechanism can be in firm contact with the ground, thereby compensating for the situation where the positioning mechanism is unstable due to uneven ground and cannot be in firm contact with the ground.

[0054] In this scheme, the propulsion beam positioning mechanism allows the propulsion beam 5 to move to different positions under the drive of the frame 2, rocker arm 3, swing arm 4, and rotary assembly 405, thereby achieving 360° full coverage of the tunnel cross section for rock drilling.

[0055] This application also provides a rock drilling rig, including the rock drilling rig propulsion beam positioning mechanism, with the base 1 connected to the frame of the rock drilling rig.

[0056] The terms "installation," "setup," "equipped with," and "connection" used in this application should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0057] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
