Description

Technical Field

[0001] The present invention relates to an anchor drill, specifically a follow-up arm type single-rail anchor drill, belonging to the technical field of roadway tunneling machinery. Background Art

[0002] At present, in the roadway tunneling construction of coal mines or non-coal mines in China, the tunneling machines, rock drilling jumbo, tunnel drills (drilling water exploration air holes), anchor drill trucks and drilling and loading units used are all equipment that travels on the ground by crawler or tire. Such roadway construction equipment traveling on the ground occupies a certain ground space size. Since the cross-sectional size of the roadway is relatively narrow, when these equipment need to enter the narrow roadway for construction operations, the construction equipment of the previous process must be withdrawn first, and then the equipment of this process is driven in and corresponding construction operations are carried out; during this process, there is a long time of "empty roof". If the geological conditions are not good and there is a large rock burst, the roadway is prone to collapse during the empty roof, and serious accidents may occur in severe cases.

[0003] In addition, in order to ensure the safe passing of construction equipment, some mines widen the roadway, and some mines make "passing bays" at certain intervals in the roadway. Whether widening the roadway or making "passing bays", it will affect the geological structure and increase the roadway tunneling and support costs; and the frequent entry and exit of equipment in the roadway to pass each other will take a lot of time, and a lot of manual cooperation is required to direct the reverse or forward movement of the vehicle, etc. Coupled with the poor lighting in the roadway, collisions are also likely to occur during the passing process. Therefore, whether it is "empty roof" or passing each other, there are safety hazards, which affect the construction efficiency and result in a low tunneling footage of the roadway.

[0004] And now there are also suspended rail drilling and anchoring equipment on the market being used, but such suspended rail equipment generally adopts a wing-type arm mechanism, as Figure 13 shown, it is necessary to lower the drill arm platform through the wing-type arm mechanism and then erect the drilling rig assembly to drill. The following problems exist in the use process:

[0005] 1. The drilling rig assembly can only be erected to drill around the cross-section and cannot drill forward;

[0006] 2. The drilling rig assembly cannot adjust its own position height according to the cross-section size and cannot adapt to the working conditions of higher roadways;

Moreover, a unique translational drill arm mechanism is used to connect the follow-up operating mechanism and the central frame, so as to drive the follow-up operating mechanism and the bolt drill assembly to swing up, down, left and right and adjust the length through the translational drill arm mechanism, so as to move the follow-up operating mechanism and the bolt drill assembly to any position in the roadway, greatly simplifying the overall structure of the machine and improving the operation convenience and application range of the whole machine.

[0034] Third, the present invention enables the bolt drill assembly to perform 360° dead-angle-free omnidirectional operations as a whole by using the follow-up operating mechanism. Moreover, a follow-up design is adopted between the follow-up operating mechanism and the bolt drill assembly, making the construction of workers more convenient and safer.

[0074] In one embodiment, two front telescopic outer sleeves 63 are symmetrically installed on one side of the upper surface of the central frame 101. The inner side walls of two front telescopic outer sleeves 63 are both slidably connected with front telescopic inner linings 61. Front telescopic oil cylinders 62 are installed between the front telescopic inner linings 61 and the front telescopic outer sleeves 63. One end of the front telescopic inner lining 61 and the bottom of the inner side wall of the front telescopic outer sleeve 63 are both installed with rollers 69;

[0075] On the other side of the upper surface of the central frame 101, two rear telescopic outer sleeves 65 are symmetrically installed. The inner side walls of the two rear telescopic outer sleeves 65 are both slidably connected with rear telescopic inner linings 66. Rear telescopic oil cylinders 64 are installed between the rear telescopic outer sleeves 65 and the rear telescopic inner linings 66. One end of the rear telescopic inner lining 66 and the bottom of the inner side wall of the rear telescopic outer sleeve 65 are both installed with rollers 69. On the side of the central frame 101 close to the rear telescopic inner lining 66, two hydraulic upper support assemblies 67 are symmetrically installed;

[0076] By using the piston rod of the front telescopic oil cylinder 62 to push the front telescopic inner lining 61 to move, the moving front telescopic inner lining 61 slides in the front telescopic outer sleeve 63, and drives the translational drill arm mechanism 2, the follow-up operation mechanism 3 and the anchor drill assembly 103 to move horizontally as a whole, so as to horizontally adjust the translational drill arm mechanism 2, the follow-up operation mechanism 3 and the anchor drill assembly 103 as a whole according to actual needs; By using the hydraulic upper support assembly 67 to contact the top of the roadway, support is provided for the top of the anchor drill.

[0077] In one embodiment, the follow-up arm type single-rail anchor drill is a front-two-rear-two follow-up arm type single-rail anchor drill. Among them, both the translational drill arm mechanism 2 and the follow-up operation mechanism 3 are four groups; One end of the telescopic outer wall 204 of the two groups of translational drill arm mechanisms 2 far from the telescopic inner wall frame 203 and one end of the piston rod of the two boom cylinders 206 are both hinged to the inner side wall of the front telescopic inner lining 61. One end of the telescopic outer wall 204 of the other two groups of translational drill arm mechanisms 2 far from the telescopic inner wall frame 203 and one end of the piston rod of the two boom cylinders 206 are both hinged to the inner side wall of the rear telescopic inner lining 66. Two hydraulic main legs 68 are symmetrically installed at the bottom of the central frame 101. One side of each of the two hydraulic main legs 68 is installed with a hydraulic side leg 70;

[0078] By using the four groups of translational drill arm mechanisms 2 and the follow-up operation mechanism 3, so that a single anchor drill can have four working positions at the same time to improve the construction efficiency. However, the power required for the overall drive of the anchor drill will also increase. Therefore, a power station assembly needs to be installed between the track mechanism 4 and the central frame 101; By expanding the hydraulic main legs 68, the contact area between the anchor drill and the ground can be increased by using the hydraulic main legs 68, and the side walls of the roadway can be squeezed and fitted by the hydraulic side legs 70 to form a vehicle stabilizing mechanism to improve the stability of the anchor drill during operation.

[0079] When the present invention is in operation: First, according to actual requirements, the bolt drill is installed at a designated position. When it is necessary to drive the entire bolt drill to move along the direction of the guide rail 404, the output shaft of the assembly motor 506 drives the driving traction wheel 504 to rotate. The rotating driving traction wheel 504 cooperates with the guide rail 404 to drive the overall movement of the central frame 101 by means of friction, and the overall movement direction of the central frame 101 can be changed by controlling the rotation direction of the driving traction wheel 504. After the central frame 101 moves to the designated position, the braking assembly between the track mechanism 4 and the central frame 101 can be used to brake the overall central frame 101.

[0080] When it is necessary to support the top, two sides or the heading face of the roadway, the support platform 102 is driven to move by using the support connecting piece 104, and then the support platform 102 is unfolded for support to ensure construction safety.

[0081] When it is necessary to adjust the positions of the follow-up operating mechanism 3 and the bolt drill assembly 103, the overall positions of the follow-up operating mechanism 3 and the bolt drill assembly 103 are adjusted for lifting and left-right swinging by the telescopic movement of the piston rod of the translation cylinder 202 in cooperation with the boom cylinder 206. The length of the telescopic inner wall frame 203 and the telescopic outer wall 204 can also be adjusted by controlling the telescopic movement of the piston rod of the telescopic drive cylinder 205 to meet the needs of adjusting the position of the bolt drill assembly 103 on the follow-up operating mechanism 3.

[0082] When it is necessary to perform drilling operations, the hydraulic main leg 68 is unfolded to increase the contact area between the bolt drill and the ground by using the hydraulic main leg 68, so as to further improve the stability of the bolt drill during operation. Then, the bolt drill assembly 103 can be directly used for drilling operations, and each translation drill arm mechanism 2 and the follow-up operating mechanism 3 are operated independently and do not interfere with each other. Drilling can be carried out in the full section or at the heading face. When the translation drill arm mechanism 2 is in construction operation, the overall positions of the follow-up operating mechanism 3 and the bolt drill assembly 103 can be further controlled to drill multiple rows of bolt and cable holes at one time in a stable machine state.

[0083] When it is necessary to adjust the horizontal positions of the translation drill arm mechanism 2, the follow-up operating mechanism 3 and the bolt drill assembly 103 as a whole, the piston rod of the front telescopic cylinder 62 pushes the front telescopic inner lining 61 to move. The moving front telescopic inner lining 61 slides in the front telescopic outer sleeve 63 and drives the translation drill arm mechanism 2, the follow-up operating mechanism 3 and the bolt drill assembly 103 to move horizontally, so as to horizontally adjust the translation drill arm mechanism 2, the follow-up operating mechanism 3 and the bolt drill assembly 103 as a whole according to actual requirements.

[0084] When it is necessary to adjust the drilling direction of the entire bolt drill assembly 103, the output shaft of the first spiral swing oil cylinder 302 drives the entire bolt drill assembly 103 to rotate around the Y-axis, so as to preliminarily adjust the drilling direction of the bolt drill assembly 103. Then, the output shaft of the second spiral swing oil cylinder 304 drives the first spiral swing oil cylinder 302 and the entire bolt drill assembly 103 to rotate around the X-axis, so as to further adjust the drilling of the bolt drill assembly 103 according to actual needs, enabling the entire bolt drill assembly 103 to perform 360° dead-angle-free and all-round operations.

[0085] Embodiment 2

[0086] As Figures 1 - 12 shown, the embodiment of the present invention also provides a follow-up arm type single-rail bolt drill, including a drill assembly 1 and a translational drill arm mechanism 2. The drill assembly 1 includes a central frame 101, a support platform 102, a bolt drill assembly 103, and a support connecting piece 104;

[0087] Among them, the support connecting piece 104 is hinged to one side of the central frame 101, the support platform 102 is installed on the other side of the support connecting piece 104, the bolt drill assembly 103 is arranged below the support platform 102, a translational drill arm mechanism 2 is installed outside the central frame 101, a follow-up operation mechanism 3 is installed on the side of the translational drill arm mechanism 2 away from the central frame 101, the bolt drill assembly 103 is installed on one side of the follow-up operation mechanism 3, a track mechanism 4 is arranged above the central frame 101, and a drive assembly 5 is installed between the track mechanism 4 and the central frame 101;

[0088] Among them, the translational drill arm mechanism 2 is used to drive the follow-up operation mechanism 3 and the bolt drill assembly 103 to swing up, down, left, and right, and has a lengthwise telescopic adjustment function;

[0089] Among them, the follow-up operation mechanism 3 is used to cooperate with the translational drill arm mechanism 2 to adjust the direction of the bolt drill assembly 103 and move synchronously with the bolt drill assembly 103;

[0090] Among them, the track mechanism 4 is used to hang the bolt drill on the top of the roadway for operation;

[0091] Among them, the drive assembly 5 is used to cooperate with the track mechanism 4 to drive the bolt drill to move on the top of the roadway

[0092] The difference from the first embodiment is that the follow-up arm type single-track bolt drill is a front-two follow-up arm type single-track bolt drill. Among them, both the translational drill arm mechanism 2 and the follow-up operation mechanism 3 are in two groups; the ends of the telescopic outer walls 204 of the two groups of translational drill arm mechanisms 2 away from the telescopic inner wall frame 203 and the piston rod ends of the two boom cylinders 206 are all hinged to the inner side wall of the front telescopic lining 61. Four hydraulic main legs 68 are symmetrically installed at the bottom of the central frame 101, and hydraulic side legs 70 are installed on one side of each of the four hydraulic main legs 68;

[0093] By reducing the number of the translational drill arm mechanism 2 and the follow-up operation mechanism 3, the overall structure of the bolt drill is made more compact, so as to correspond to the tunneling operation in narrow roadways, and the power requirement for driving the bolt drill is reduced; by expanding the hydraulic main legs 68, the contact area between the bolt drill and the ground can be increased by using the hydraulic main legs 68, and the side walls of the roadway are squeezed and fitted by the hydraulic side legs 70 to form a vehicle stabilizing mechanism, so as to improve the stability of the bolt drill during operation.

[0094] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
