Description

Technical Field

[0001] The invention relates to the technical field of rock drilling arms, in particular to a telescopic translational drill arm mechanism and a rock drilling trolley. Background Art

[0002] A rock drilling rig, also known as a drilling rig, is a type of rock drilling equipment used in tunnel and underground projects using the drill and blast method. The rock drilling rig was introduced in the early 1980s and can move and support multiple rock drills to perform drilling operations simultaneously.

[0003] The existing rock drilling rig is mainly composed of a rock drill, a drill arm (the support, positioning and propulsion mechanism of the rock drill), a steel frame, a traveling mechanism and other necessary auxiliary equipment. When the drilling method is used to excavate a tunnel, favorable conditions are provided for the use of the rock drilling rig. The combination of the rock drilling rig and the ballast loading equipment can speed up the construction, increase labor productivity and improve working conditions.

[0004] For example, the Chinese invention patent with the authorization announcement number: CN105201405B discloses a propulsion device for a rock drill, including: a propulsion beam; a sliding base plate, which is movably arranged on the propulsion beam and used to set the rock drill; a propulsion cylinder, which is arranged on the propulsion beam and used to push the sliding base plate to move; and a displacement sensor, which is arranged on the propulsion cylinder and used to monitor the movement position of the sliding base plate in real time. Since the displacement sensor can monitor the displacement of the rock drill in real time, when the drilling depth needs to be changed, the displacement sensor can be directly arranged so that it can respond accordingly when the sliding base plate moves to the required amount of movement.

[0005] When the telescopic and translational drill arm mechanism in the prior art is in use, the rubber block at the front end of the propulsion device is usually pressed against the working surface to provide positioning for subsequent drilling. However, due to the low flatness of the drilling working surface, the single-point positioning effect is poor. In the prior art, a drill support is respectively arranged at the front and middle of the propulsion beam, and the drill rod is passed through the two drill supports in sequence to ensure that the drill rod is stably extended in one direction. The drill rod is only supported by the front fixed drill support and a single middle movable drill support. The span between the two drill supports and the span between the middle drill support and the rock drill are both large. When the drill rod is highly rotated, it is difficult to ensure the stability of the drill rod. The drill rod is prone to violent shaking, which affects the smooth drilling of the drill rod.

A connecting rod 1 614 is hingedly installed on the outer surface of the driving block 613 and at the position corresponding to the support plate 602. A connecting rod 2 615 is hingedly installed on the other end of the connecting rod 1 614. The other end of the connecting rod 2 615 movably penetrates the fixed cylinder 601 and extends to the outside of the fixed cylinder 601. One end of the connecting rod 2 615 extending to the outside of the fixed cylinder 601 is fixedly connected to a limited tooth block 616. The driving block 613 is away from the elastic support component 1 612. A return spring 2 617 is fixedly connected to one side of 12, and an extrusion block 618 is fixedly connected to the other end of the return spring 2 617. The extrusion block 618 movably passes through the fixed cylinder 601 and extends to the outside of the fixed cylinder 601. A plurality of elastic support components 2 619 are fixedly connected to the inner wall of the fixed cylinder 601, and the other end of the elastic support component 2 619 is fixedly connected to a limited position trigger block 620. The elastic force of the return spring 2 617 is greater than the elastic force of the return spring 3 6122, and the elastic force of the return spring 3 6122 is greater than the elastic force of the return spring 4 6192.

[0049] The front end and the rear end of the limit trigger block 620 are respectively provided with a first guiding slope 6201 and a second guiding slope 6202 .

[0050] The elastic telescopic mechanism 1 includes a telescopic rod 1 6121 and a return spring 3 6122. The telescopic rod 1 6121 and the return spring 3 6122 are both fixedly mounted on one side of the inner wall of the fixed cylinder 601 close to the aluminum alloy propulsion beam 1. The return spring 3 6122 is movably sleeved on the outer surface of the telescopic rod 1 6121. The telescopic rod 1 6121 and the return spring 3 6122 are both fixedly connected to the driving block 613.

[0051] The elastic support component 2 619 includes a telescopic rod 2 6191 and a reset spring 4 6192. The telescopic rod 2 6191 and the reset spring 4 6192 are both fixedly mounted on the inner wall of the fixed cylinder 601. The reset spring 4 6192 is movably sleeved on the outer surface of the telescopic rod 2 6191. The telescopic rod 2 6191 and the reset spring 4 6192 are both fixedly connected to the limit trigger block 620.

[0052] The bracket 802 is mounted on the mechanical arm of the rock drilling trolley by bolts. When drilling operation is required on the working surface, the position of the aluminum alloy push beam 1 is first adjusted by the mechanical arm on the rock drilling trolley, so that the rock drilling mechanism 9 on the aluminum alloy push beam 1 is opposite to the position to be drilled on the working surface, and then the aluminum alloy push beam 1 is pushed to the side close to the working surface by the push mechanism 2 8, and the multi-point adaptive positioning mechanism 6 is driven to move synchronously. When the rubber block 607 abuts against the working surface, the push mechanism 2 8 continues to push the aluminum alloy push beam 1 to move, so that a relative displacement occurs between the rubber block 607 and the support plate 602, that is, the rubber block 607 moves to the side close to the support plate 602, and drives the moving rod 604 to move synchronously. At this time, through Under the guiding action of the threaded groove 605 on the guide column 2 606, the guide column 2 606 and the gear 603 make a circular motion with the axis of the moving rod 604 as a circle, and when the moving rod 604 moves, the limit rod 609 and the fixed block 610 are driven to move synchronously through the connecting plate 608, and the fixed block 610 squeezes the return spring 1 611 to make it in a compressed state and store energy. When the multiple rubber blocks 607 are adaptively contracted to a suitable position according to the flatness of the working surface, that is, the multiple rubber blocks 607 are all in contact with the working surface, and then the propulsion mechanism 2 8 continues to propel the aluminum alloy propulsion beam 1 to the side close to the working surface. When the extrusion block 618 is in contact with the working surface, the extrusion block 618 and the fixed cylinder 601 are relatively displaced. That is, the extrusion block 618 moves toward the inside of the fixed cylinder 601, and squeezes the return spring 2 617 to make it in a compressed state and store energy, until the extrusion block 618 abuts against the guide slope 1 6201 at the front end of the limit trigger block 620, and the extrusion block 618 pushes the limit trigger block 620 to move to the side away from the driving block 613, so that the limit trigger block 620 releases the limit on the driving block 613. At this time, since the elastic force of the return spring 2 617 is greater than the elastic force of the return spring 3 6122, the elastic force of the return spring 2 617 can push the driving block 613 to move to the side close to the aluminum alloy propulsion beam 1, and squeeze the return spring 3 6122 to make it in a compressed state and store energy. At the same time, the driving block 613 The movement is carried out by pushing the connecting rod 1 614 to push the connecting rod 2 615 to move to the outside of the fixed cylinder 601, and driving the limiting tooth block 616 to move to the side close to the gear 603, until the limiting tooth block 616 is inserted between the adjacent teeth on the gear 603, and the gear 603 and the guide column 2 606 are limited and fixed, so that they cannot rotate, and then the moving rod 604 and the rubber block 607 are indirectly limited and fixed, and the multiple rubber blocks 607 are adaptively abutted with the working surface according to the flatness of the working surface, so as to achieve multi-point adaptive positioning, greatly improve the positioning effect of the aluminum alloy propulsion beam 1, and have stronger adaptability, whether the working surface is flat or not, it can provide stable positioning for subsequent drilling, and effectively improve the quality of subsequent drilling;

[0053] After the aluminum alloy push beam 1 is stably positioned by the multi-point adaptive positioning mechanism 6, the push slide 3 is driven to move to the side close to the working surface, that is, to the front end of the aluminum alloy push beam 1, by the push mechanism 1 7. At the same time, the rock drill 901 is started to drive the drill rod 902 to rotate and perform drilling operations on the working surface. During the movement of the rock drilling mechanism 9, that is, the movement of the push slide 3, the distance adjustment slide 503 at the bottom of the push slide 3 is driven to move synchronously, and the guide column 1 504 inside the distance adjustment slide 503 is driven to move synchronously, so that the guide column 1 504 moves in the corresponding variable pitch thread guide groove 502, so that the distance adjustment rod 501 is rotated synchronously under the guiding action of the variable pitch thread guide groove 502, thereby driving the remaining variable pitch thread guide grooves 502 to rotate synchronously and push The guide column 504 moves, thereby driving the middle drill support 4 to move, and then when the propulsion mechanism 7 drives the propulsion slide 3 and the rock drilling mechanism 9 to move for drilling operations, it can drive multiple middle drill supports 4, front drill supports 2 and propulsion slide 3 to perform equidistant variable distance adjustment, so that when the rock drilling mechanism 9 moves forward for drilling operations, multiple middle drill supports 4 are always equidistantly distributed between the front drill support 2 and the propulsion slide 3. Through the coordinated use of multiple equidistant variable distance adjusted middle drill supports 4 and front drill supports 2, the span between adjacent supporting parts of the drill rod 902 can be reduced to ensure stable support for the drill rod 902, avoid violent shaking of the drill rod 902 during high-speed rotation drilling operations, ensure smooth drilling of the drill rod 902, and effectively improve the efficiency and quality of the drilling operation.

[0054] The present invention also provides a rock drilling rig, which includes a drill arm mechanism. The drill arm mechanism adopts the telescopic and translational drill arm mechanism as described above.
