DETAILED DESCRIPTION

[0035] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, and are not a limitation on the present application. In addition, it should be noted that, for ease of description, only the parts related to the present application are shown in the drawings, rather than all the structures.

[0036] As shown in Figure 1 , the present embodiment discloses a portable anchor rod drilling construction angle control device, which comprises a drill bit guide tube 30, an upper support assembly 40, a lower support assembly 50, and an angle adjustment assembly 60.

[0037] The left and right ends of the upper support assembly 40 are respectively used for mounting to the left side steel arch 12 and the right side steel arch 11. The left and right ends of the lower support assembly 50 are respectively used for mounting to the left side steel arch 12 and the right side steel arch 11. The upper support assembly 40 and the lower support assembly 50 are arranged at intervals, and the upper support assembly 40 is located above the lower support assembly 50.

[0038] The structure of the lower support assembly 50 is as shown in Figure 2As shown, the lower support assembly 50 comprises a left rod body 51 and a right telescopic rod 52, and the left rod body 51 is connected with the right telescopic rod 52 through a telescopic rod connector 53. The structure of the telescopic rod connector 53 is as shown in the following figure. Figure 7

[0039] The tube body 531 of the telescopic rod connector 53 is divided into left and right two parts, and the inner wall of the left part 5311 is smooth. The inner wall of the right part 5312 is a threaded structure. The outer wall of the tube body 531 of the telescopic rod connector 53 is provided with a rotating handle 532. The rotating handle 532 is welded with the tube body 531.

[0040] The left rod body 51 is a thick-walled hollow steel pipe, and the diameter of the right end of the left rod body 51 is slightly smaller than the diameter of the telescopic rod connector 53, so that the right end of the left rod body 51 can be sleeved with the left part 5311 of the telescopic rod connector 53, and after the sleeving, the telescopic rod connector 53 can rotate relative to the left rod body 51.

[0041] The right telescopic rod 52 is a threaded rod, and the right telescopic rod 52 is screwed with the right part 5312 of the telescopic rod connector 53. Rotating the rotating handle 532 of the telescopic rod connector 53 can make the right telescopic rod 52 telescopic, thereby adjusting the length of the whole lower support assembly 50, so as to adjust the length and installation stability of the whole lower support assembly 50, and ensure that the whole lower support assembly 50 can adapt to the change of the distance between the right steel arch 11 and the left steel arch 12.

[0042] The left end of the lower support assembly 50 is provided with a left fixing clamp 54 and a bolt 56, and the right end of the lower support assembly 50 is provided with a right fixing clamp 55 and a bolt 56. Specifically, the left end of the left rod body 51 is provided with a left fixing clamp 54 and a bolt 56, and the right end of the right telescopic rod 52 is provided with a right fixing clamp 55 and a bolt 56.

[0043] The left fixing clamp 54 and the bolt 56 are used for detachable connection with the left steel arch 12. The right fixing clamp 55 and the bolt 56 are used for detachable connection with the right steel arch 11.

[0044] The installation process of the lower support assembly 50 is as follows: after selecting the anchor rod construction area, first, install the lower support assembly 50 on the right steel arch 11 and the left steel arch 12, so that the lower support assembly 50 is perpendicular to the right steel arch 11 and the left steel arch 12. Adjust the length of the lower support assembly 50 through the rotating handle 532, so as to adapt to the length of the right steel arch 11 and the left steel arch 12. Connect and fix the left fixing clamp 54 and the bolt 56 with the left steel arch 12, and connect and fix the right fixing clamp 55 and the bolt 56 with the right steel arch 11.

[0045] ​The left and right fixing clamps 54 and 55 are tightened by rotating the bolt 56, and the fixing clamps do not slide or rotate relative to the steel arch.

[0046] The structure of the upper support assembly 40 is shown in Figure 3 The structure of the upper support assembly 40 is similar to that of the lower support assembly 50, except that the upper support assembly 40 is provided with a guide pipe positioner 70.

[0047] Specifically, the upper support assembly 40 includes a left rod body 41, a right telescopic rod 42, a telescopic rod connecting piece 43, a left fixing clamp 44, a right fixing clamp 45, and a bolt 46.

[0048] The left rod body 41 is provided with a plurality of spaced-apart clamping grooves 411 along the length direction, and the clamping grooves 411 are in communication with the inner cavity of the left rod body 41. The clamping grooves 411 are used to install the guide pipe positioner 70.

[0049] The installation and adjustment of the upper support assembly 40 are the same as those of the lower support assembly 50.

[0050] The installation process of the upper support assembly 40 is as follows: the upper support assembly 40 is installed on the right steel arch 11 and the left steel arch 12 at a suitable position above the lower support assembly 50, so that the upper support assembly 40 is perpendicular to the right steel arch 11 and the left steel arch 12 and parallel to the lower support assembly 50. The length of the upper support assembly 40 is adjusted by rotating the handle to adapt to the length of the right steel arch 11 and the left steel arch 12. The left fixing clamp 44 and the bolt 46 are connected and fixed to the left steel arch 12, and the right fixing clamp 44 and the bolt 46 are connected and fixed to the right steel arch 11. The left and right fixing clamps 44 and 45 are tightened by rotating the bolt 46, and the fixing clamps do not slide or rotate relative to the steel arch.

[0051] The structure of the angle adjustment assembly 60 is shown in Figure 4 The structure of the angle adjustment assembly 60 is the same as that of the lower support assembly 50. The angle adjustment assembly 60 includes a left rod body 61, a right telescopic rod 62, a telescopic rod connecting piece 63, a left fixing clamp 64, a right fixing clamp 65, and a bolt 66.

[0052] The installation process of the angle adjustment assembly 60 is as follows: the right fixing clamp 65 of the angle adjustment assembly 60 is connected to the left rod body 51 of the lower support assembly 50. The left rod body 61 of the angle adjustment assembly 60 is waiting to be connected to the drill bit guide pipe 30. The angle adjustment assembly 60 is perpendicular to the upper support assembly 40 and the lower support assembly 50 to ensure the accuracy of vertical adjustment, and there is no contact between the angle adjustment assembly 60 and the upper support assembly 40, which facilitates the adjustment of the height of the angle adjustment assembly 60.

[0053] The structure of the drill bit guide pipe 30 is shown in Figure 5 The drill bit guide pipe 30 is the core component of the embodiment, and the position of the drill bit guide pipe 30 finally determines the angle of the drilling rig drilling and the anchoring rod erection. The drill bit guide pipe 30 is a hollow steel pipe. The drill bit guide pipe 30 mainly relies on the guide pipe positioner 70 to adjust the angle.

[0054] The structure of the guide pipe positioner 70 is shown in Figure 6 The guide pipe positioner 70 includes a fixed clamping plate 71, a guide pipe limiting ring 72, a limiting hole 73, a telescopic buckle 74, and a scale disc 75. The guide pipe limiting ring 72 is rotatably installed on the fixed clamping plate 71, and the guide pipe limiting ring 72 has a scale pointer. The guide pipe limiting ring 72 is used for the drill bit guide pipe 30 to pass through, and the angle of rotation of the guide pipe limiting ring 72 is determined by the scale disc 75 to determine the angle of the drill bit guide pipe 30.

[0055] Specifically, a preset clamping groove 411 is selected as needed, the fixed clamping plate 71 is installed in the preset clamping groove 411 of the upper support assembly 40, and is positioned by the telescopic buckle 74. At this time, the position of the guide pipe positioner 70 is fixed. Then the drill bit guide pipe 30 passes through the guide pipe limiting ring 72, the guide pipe limiting ring 72 can rotate, and the angle of rotation of the guide pipe limiting ring 72 is determined by the scale disc 75 to determine the angle of the drill bit guide pipe 30, thereby determining the final angle of the anchoring rod.

[0056] The telescopic rod connecting piece 63 of the angle adjustment assembly 60 is rotated to adjust the vertical height of the angle adjustment assembly 60, so that the left side fixing clamp 64 of the angle adjustment assembly 60 vertically extends to the drill bit guide pipe 30, and the left side fixing clamp 64 of the angle adjustment assembly 60 is connected with the drill bit guide pipe 30, and is fixed by the bolt 66, so that the drill bit guide pipe 30 does not rotate or translate.

[0057] The embodiment fine-tunes the lateral and longitudinal positions and the angle of the drill bit guide pipe 30 until it is adjusted to the best position.

[0058] When drilling multiple anchoring rods in a region, after completing the drilling of the first anchoring rod, only the corresponding bolts 66 of the telescopic buckle 74 of the guide pipe positioner 70 and the left side fixing clamp 64 of the angle adjustment assembly 60 need to be loosened, and then the two are moved left and right as a whole and the angle is adjusted. After reaching the specified position, the telescopic buckle 74 is fixed and the corresponding bolt 66 of the left side fixing clamp 64 of the angle adjustment assembly 60 is tightened. After the two are fixed, the drilling position is verified to ensure the accuracy of the drilling.

[0059] Before the next area working face drilling construction is carried out, the device can be disassembled in sequence according to the foregoing installation sequence, and the device is continuously used, and only the upper support assembly 40 and the lower support assembly 50 need to be removed from the right steel arch 11 and the left steel arch 12.

[0060] After all the drilling work is completed, the device is disassembled in reverse order of installation, the parts are collected and maintained, and is ready for use next time.

[0061] The guide pipe positioner 70 of the embodiment can move left and right on the left side rod body 41 of the upper support assembly 40 through the limiting hole 73, and the specific position is determined by the clamping grooves 411 and the transverse position of the anchor hole, the distance between the clamping grooves 411 can be specially customized according to the demand, and the clamping grooves 411 are uniformly distributed. The main function of the guide pipe positioner 70 is to fix the position of the drill bit guide pipe 30, ensure the stability of the drill bit guide pipe 30, and adjust the angle of the drill bit guide pipe 30.

[0062] The embodiment realizes angle control of anchor hole at any position of full section by using the stable structure composed of the upper support assembly 40, the lower support assembly 50, the angle adjusting assembly 60, the drill bit guide pipe 30 and the guide pipe positioner 70, and the drilling construction of multiple anchor rods in a region can be realized by installing the device once, the cumbersome process of “one hole one installation” is avoided, the structure is reasonable, the technology is reliable, the construction quality is guaranteed, and the construction efficiency is greatly improved.

[0063] Most of the embodiments are detachable connection modes, which are simple in structure, flexible in disassembly and assembly, small in size, convenient to carry and not prone to failure, can be reused, can effectively save materials and resources, and are practical in the construction process.
