Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a hydraulic folding rotating frame of a steel cable coring tunnel drilling rig. Background Art

[0002] Traditional wire rope coring tunnel drilling rigs need to be replaced and moved every 3-5 days in underground mines. When setting up and fixing during the operation, at least 6 people are needed on site to level the site, lay anti-skid wooden planks, and install the wire rope coring tunnel drilling rig. The installation operation sequence of the traditional wire rope coring tunnel drilling rig is: first install 2 screw columns, and ensure that the upper part of the screw column is tight against the rock top plate and padded with anti-skid wooden planks, and the lower part is tight against the anti-skid wooden planks on the ground, and build a scaffolding. 2 people tighten the screw, and another 2 people hold the screw column, and 1 person stands on the scaffolding to lay anti-skid wooden planks. The last 6 people measure the verticality of the screw column; the screw columns are installed in the above order. After the two screw columns are installed, two people will carry the drill rig turntable and clamp it to the two screw columns, and the other two people will install the 8 bolts of the drill rig turntable pressure plate. After the drill rig turntable is installed, two people will install the steel cable coring tunnel drill rig turntable to the drill rig turntable, and one person will tighten the two bolts behind the screw column. When the installation of the two screw columns and the drilling rig swivel head is completed, one person stands on the scaffolding and hangs a fall chain at the top of the screw column. Then four people move the steel cable core tunnel drilling rig slide to the bottom of the screw column, fasten the lifting fall chain, lift the steel cable core tunnel drilling rig slide onto the drilling rig swivel head and fix it with four bolts. Then use the fall chain to lift the hydraulic motor gearbox and fix it on the steel cable core tunnel drilling rig slide. Then lift the hydraulic motor and install it on the gearbox and fix it. Finally, remove the scaffolding and start the steel cable core tunnel drilling rig. After adjusting the drilling anchor angle, tighten the two bolts of the drilling rig swivel head, connect the hydraulic oil pipe to the steel cable core tunnel drilling rig main unit and the hydraulic pump station, start the machine to drill the anchor rod at the front end of the steel cable core tunnel drilling rig, and after drilling the anchor rod hole, connect the anchor rod and the steel cable core tunnel drilling rig, and install the connecting bolts. After loosening two bolts on the drill's swivel head, four people adjusted the cable coring tunnel drill to the correct angle for coring. They then installed the lead screw sub-column and began drilling and coring. The entire process of installing the cable coring tunnel drill and drilling the anchor holes required at least six people and over a dozen hours to complete the drill support work, which was time-consuming, labor-intensive, and posed safety risks.

[0003] When the drilling rig is subsequently relocated, workers must rebuild the scaffolding and gradually dismantle the rig. To ensure construction safety, at least six people are needed to assist in the dismantling process to prevent it from tipping over and injuring people. Once dismantling is complete, the rig must be loaded and unloaded at the next work area, repeating the installation, drilling, and dismantling process. Therefore, for construction sites requiring multiple horizontal fan-shaped holes in a roadway, the entire rig must be disassembled and installed multiple times. This complex and tedious process is extremely time-consuming and labor-intensive, and safety cannot be guaranteed.

[0004] Therefore, the conventional wireline coring tunnel drilling rig still has inconveniences and defects during operation, and needs to be further improved. Therefore, how to design a wireline coring tunnel drilling rig support device that is simple to operate, low-cost, and highly safe has become the current main solution. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0034] Combine Figure 1-3As shown, this embodiment specifically discloses a hydraulic folding rotating frame of a steel cable coring tunnel drilling rig, which includes two sets of hydraulic support main columns 3, at least one set of hydraulic column support cylinders 4, a folding frame base 1, a horizontal rotating base 19 and a rotating lifting cylinder 18.

[0035] Specifically, in this embodiment, the horizontal rotating base 19 is located below the folding frame base 1, the rotating lifting cylinder 18 is located at the center of the horizontal rotating base 19, and the cylinder body of the rotating lifting cylinder 18 is fixedly connected to the folding frame base 1, and the folding frame base 1 is driven to rise and fall by the rotating lifting cylinder 18, and the folding frame base 1 can rotate around the center of the horizontal rotating base 19; More specifically, in this embodiment, the side of the rotating lifting cylinder 18 is connected to a rotating lifting cylinder bracket 17, as shown in FIG. Figure 1 As shown, the rotary lift cylinder bracket 17 of this embodiment uses four connecting rods, which are respectively connected to the four corners of the folding frame base 1 through the four connecting rods, thereby fixing the folding frame base 1 to the rotary lift cylinder 18. The folding frame base 1 can be lifted and lowered by the telescopic action of the rotary lift cylinder 18. As the cylinder body and telescopic rods in the rotary lift cylinder 18 can rotate relative to each other in the circumferential direction, the folding frame base 1 and the horizontal rotating base 19 can also rotate in the circumferential direction, thereby enabling the hydraulic folding rotary frame of the steel cable core tunnel drilling rig to achieve horizontal drilling angle adjustment. In addition, this embodiment is provided with a manual hydraulic pump 20 on the side of the folding frame base 1. The manual hydraulic pump 20 can manually provide hydraulic pressure to the rotary lift cylinder 18 to control its lifting action. Of course, in addition to the manual control method, this embodiment can also integrate its control method with other hydraulic control methods and adopt automatic control method for operation.

[0036] Furthermore, the folding frame base 1 in this embodiment includes two longitudinal fixing rods and two connecting beams, wherein the two longitudinal fixing rods are arranged in parallel, and the two connecting beams are located in front and behind the longitudinal fixing rods, and the two ends of each connecting beam are vertically connected to the longitudinal fixing rods respectively, and the longitudinal fixing rods and the connecting beams constitute a rectangular plane frame. The front side of the folding frame base 1 is hinged with two column mounting rods 2, and each column mounting rod 2 is connected to a group of the hydraulic support main columns 3, and a main column support cross bar 5 is provided between the lower parts of the two groups of hydraulic support main columns 3. The two ends of the main column support cross bar 5 are respectively fixedly connected to the hydraulic support main columns 3 at the corresponding ends. In this embodiment, the hydraulic column support cylinder 4 is provided with at least one group, preferably two groups, wherein one end of the hydraulic column support cylinder 4 is connected to the main column support cross bar 5, and the other end is connected to the rear side of the folding frame base 1, preferably hingedly connected to the connecting beam on the rear side of the folding frame base 1, and the hydraulic support main column 3 is pushed and lifted or folded through the telescopic action of the hydraulic column support cylinder 4. The folded steel cable core tunnel drilling rig hydraulic folding rotating frame can reduce the transportation space and is more convenient for relocation and transportation.

[0037] Furthermore, in this embodiment, a hydraulic balancing cylinder 13 is provided on the connecting crossbeam on the rear side of the folding frame base 1. The hydraulic balancing cylinder 13 is located between the two sets of hydraulic column support cylinders 4. The hydraulic balancing cylinder 13 is used to balance the hydraulic pressure of the two sets of hydraulic column support cylinders 4, so that the two sets of hydraulic column support cylinders 4 are opened and raised synchronously. It should be noted that the purpose of providing the hydraulic balancing cylinder 13 between the two sets of hydraulic column support cylinders 4 in this embodiment is mainly to balance the hydraulic force of the two sets of hydraulic column support cylinders 4, so as to ensure that the extension and contraction of the two sets of hydraulic column support cylinders 4 are synchronized, thereby ensuring that the hydraulic support main column 3 is evenly stressed and supported, and avoiding distortion caused by the asynchronous operation of the two sets of hydraulic column support cylinders 4.

[0038] In addition, a hydraulic swivel support beam 7 is installed between the two sets of hydraulic support main columns 3 in this embodiment. A lower slide 8 is connected to the hydraulic swivel support beam 7. More specifically, the lower slide 8 has slots on both sides that connect to the bottom edges of the drill rig 10. These slots clamp the bottom edges of the drill rig 10, thereby securing the drill rig 10 to the lower slide 8. In this embodiment, when the slots in the lower slide 8 are released, the wireline coring tunnel drill rig can move forward and backward, adjusting the clearance between the front end of the wireline coring tunnel drill rig and the rock face to facilitate drilling operations. Furthermore, a hydraulic rotator 9 is installed at one end of the hydraulic swivel support beam 7. During drilling operations, the hydraulic rotator 9 can be controlled to rotate, thereby driving the drill rig 10 to rotate 180 degrees up and down around the axis of the hydraulic swivel support beam 7. Combined with the 360-degree rotation adjustment of the rotary lift cylinder 18 in this embodiment, drilling operations can be performed at any position within a given space.

[0039] Furthermore, to improve the stability of the drilling rig 10 during the drilling process, this embodiment further provides at least one set of hydraulic support secondary columns 11 on the folding frame base 1, wherein the hydraulic support secondary columns 11 are detachably connected to the folding frame base 1. When the device is folded, the hydraulic support secondary columns 11 can be removed, and when performing support, the hydraulic support secondary columns 11 can be installed on the folding frame base 1. Furthermore, in this embodiment, a secondary column support cross bar 12 is connected to the hydraulic support secondary columns 11. The secondary column support cross bar 12 is connected to the rear of the drilling rig 10. The rear of the drilling rig 10 can be supported by the secondary column support cross bar 12, thereby maintaining the drilling angle of the drilling rig 10.

[0040] It should be noted that in this embodiment, both the hydraulically supported main column 3 and the hydraulically supported secondary column 11 are equipped with a hydraulic lock 6. This lock 6 is used to maintain the support height of the corresponding hydraulically supported column under a certain load. The specific structure and connection structure of the hydraulic lock 6 can be adapted from existing hydraulic structures and can be adaptively adjusted as the overall structure changes, so a detailed description is not provided here.

[0041] More specifically, in this embodiment, column supports 21 and drill rig supports 22 are provided on the folding frame base 1. These supports are intended to support the hydraulically supported main columns 3 and the drill rig 10 when the hydraulically folding rotary frame of the wireline coring tunnel drill rig is folded, preventing deformation and thereby extending the life of the equipment. Specifically, two sets of column supports 21 are located on either side of the folding frame base 1, and the tops of the column supports 21 are provided with arcuate mounting grooves that mate with the sides of the hydraulically supported main columns 3. The drill rig support 22 is located between the two sets of column supports 21 and utilizes a gate-shaped structure. The top of the drill rig support 22 provides jacking support for the rear portion of the drill rig 10.

[0042] At the same time, in this embodiment, to facilitate equipment operation, a multi-angle folding hydraulic operating platform 14 is provided on the rear side of the folding frame base 1. The multi-angle folding hydraulic operating platform 14 can be used to control the hydraulic support main column 3, hydraulic column support cylinder 4, folding frame base 1, horizontal rotation base 19, and rotary lifting cylinder 18 in the equipment, thereby supporting the drilling rig 10. The multi-angle folding hydraulic operating platform 14 is supported by a supporting gas spring 15, which is connected to a gas spring switch 16. The gas spring switch 16 and the supporting gas spring 15 can be used to adjust the height of the multi-angle folding hydraulic operating platform 14. Furthermore, the gas spring switch 16 in this embodiment is provided with a metal structural frame, and the multi-angle folding hydraulic operating platform 14 can be installed on the metal structural frame of the gas spring switch 16. The bottom of the metal structural frame is hinged to the folding frame base 1. When folding is required, only the gas spring switch 16 needs to be pulled to remove the supporting force of the supporting gas spring 15, and the multi-angle folding hydraulic operating platform 14 and the metal structural frame can be folded; and when drilling operations are performed, the metal structural frame is lifted and fixed by the supporting gas spring 15, which makes it convenient for construction personnel to operate the multi-angle folding hydraulic operating platform 14.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
