Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor rod drilling machine, especially a small empty help distance roof anchor rod drilling machine adjusting mechanism for coal mine. BACKGROUND

[0002] In the complex environment of coal mining, coal roadway support is the key link to ensure mine safety and improve mining efficiency, and its importance is self-evident. Anchor rod machine can quickly and accurately complete the drilling and anchor rod installation task, and reduce the burden of workers. The anchor rod drilling machine is divided into roof anchor rod drilling machine and side anchor rod drilling machine. The roof anchor rod drilling machine is arranged behind the shovel plate and in front of the track of the tunneling and anchoring machine, and is arranged as four parts, two parts on the left and right, anchoring the roof anchor rod and anchor cable. The side anchor rod drilling machine is arranged in the middle of the tunneling and anchoring machine, anchoring the side anchor rod and anchor cable, and one part on the left and right.

[0003] However, most of the tunneling and anchoring machines on the market are roof anchor rod drilling machines that can only anchor the roof, or side anchor rod drilling machines that can only anchor the side, and cannot realize the function of one machine with multiple functions. In addition, the biggest disadvantage of this equipment is that the empty roof distance of the side anchor rod is too large, and the flexibility is too small. Especially in the mine area with complex geological conditions and variable coal seam thickness, the roof and side empty roof time is long, which affects the support efficiency, and further causes the roof to fall off, the side to explode, and other phenomena, which affects the tunneling efficiency. The traditional support method has been difficult to meet the production requirements of modern mines, seriously restricting the output and efficiency of coal mines, and posing a major threat to mine safety production.

[0022] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0023] Please see the appendix Figures 1-3 As shown, an adjustment mechanism for a small-gap top anchor bolt drilling rig used in coal mines is symmetrically arranged on both sides of the drilling rig.

[0024] Specifically, it includes an external drilling rig 1 for top anchor bolts and an internal drilling rig 2 for side anchor bolts. The internal drilling rig 2 is located near the sidewall of the roadway and can be used for both side anchor bolts and top anchor bolts.

[0025] The internal drilling rig 2 is connected to a lifting cylinder 3. A rotating mechanism 4 is fixed on the slider of the lifting cylinder 3. The internal drilling rig 2 is driven to rotate left and right to adjust the side anchoring angle through the rotating mechanism 4. The back of the lifting cylinder 3 is also provided with a swing mechanism 5 for driving the internal drilling rig 2 to swing back and forth to adjust the angle. Under the action of multiple adjustment mechanisms, the internal drilling rig 2 can slide and rotate in multiple directions such as front and back, up and down, left and right, and has the ability to rotate 360° with the front and back direction as the axis, so as to achieve all-round and dead-angle operation capability.

[0026] Because the distance between the internal drilling rig 2 and the external drilling rig 1 is relatively short, and the drilling rig itself is quite long when anchoring, the external drilling rig 1 is connected to a side sliding mechanism 6 to facilitate the side anchoring of the internal drilling rig 2. The side sliding mechanism 6 drives the external drilling rig 1 to move laterally to make way for the internal drilling rig 2 when rotating. Both the external drilling rig 1 and the external drilling rig 2 are connected to a front and rear sliding mechanism 7, which can drive the drilling rig to move forward to achieve anchoring with a small gap between the top and bottom.

[0027] As attached Figure 4 and attached Figure 5 As shown, the rotating mechanism 4 includes a support 41, a rotating cylinder 42, and a connecting plate 43 fixedly connected to the internal drilling rig 2. The support 41 is fixedly connected to the slider on the lifting cylinder 3. The bottom end of the rotating cylinder 42 is hinged to the top of the support 41, and the telescopic end of the rotating cylinder 42 is hinged to the top of the connecting plate 43. The bottom of the connecting plate 43 is rotatably connected to the slider on the lifting cylinder 3. The telescopic end of the rotating cylinder 42 drives the internal drilling rig 2 to rotate left and right, that is, it can rotate around the top plate drilling rig as an axis, which can anchor the side walls and corner anchors. The rotation state of the internal drilling rig 2 is shown in the attached figure. Figure 3 As shown.

[0028] Please see the appendix Figure 4 As shown, the swing mechanism 5 includes a base 51, a swing cylinder 52, and a triangular plate 53 fixed to the back of the lifting cylinder 3. The bottom end of the triangular plate 53 is hinged to the side of the base 51, the swing cylinder 52 is hinged to the top of the base 51, and the telescopic end of the swing cylinder 52 is hinged to the top of the triangular plate 53. Its working principle is the same as that of the rotating mechanism 4, only the direction of rotation is different. The swing mechanism 5 can adjust the position of the drilling rig back and forth, which is convenient for hole alignment. Since the rotating mechanism 4 is fixed on the slider of the lifting cylinder 3, the swing cylinder 52 will drive the rotating mechanism 4 and the internal drilling rig 2 to swing back and forth together when working.

[0029] In this embodiment, the internal drilling rig 2 can be used not only for top anchor bolts but also for side anchor bolts. When making top anchor bolts, there is no need to adjust the swing mechanism 5 and the rotation mechanism 4; the internal drilling rig 2 can simply be arranged vertically.

[0030] Please see the appendix Figure 6As shown, the side sliding mechanism 6 comprises a side sliding oil cylinder 61, a movable block 62 and a connecting plate two 63 fixedly connected with the external drilling machine 1, the telescopic end of the side sliding oil cylinder 61 is fixedly connected with the movable block 62, the movable block 62 is fixedly connected with the bottom of the connecting plate two 63, the left and right movement of the external drilling machine 1 is realized through the side sliding oil cylinder 61, the distance of the drilling machine is adjusted, the distance between anchor rods is adjusted, the external drilling machine 1 is only used for top anchor rod, therefore, the external drilling machine 1 is not provided with the rotating mechanism 4 and the swinging mechanism 5, the internal drilling machine 2 cooperates with the external drilling machine 1, the top anchor rod and the side anchor rod are simultaneously performed, and the working efficiency is improved.

[0031] Among them, the two front and rear sliding mechanisms 7 are front and rear pushing oil cylinders, the telescopic ends of the pushing oil cylinders are respectively fixedly connected with the base 51 and the side sliding oil cylinder 61, and the front and rear pushing oil cylinders and the side sliding oil cylinder 61 are vertically arranged.

[0032] In the above embodiment, preferably, the front and rear pushing oil cylinders are provided with protective shells on the side sliding oil cylinder 61.

[0033] Specific working process:

[0034] When the roof anchor rod and anchor cable are performed, the external drilling machine 1 and the internal drilling machine 2 are first made perpendicular to the roof, the external drilling machine 1 is operated to move forward by a certain distance, and then the roof anchor rod and anchor cable are anchored, at this time, the empty roof distance of the roof anchor rod drilling machine is greatly reduced, the anchor rod is close to the head when anchoring, and small empty roof operation is realized. In this process, the internal drilling machine 2 can also perform the top anchor rod according to the above;

[0035] After the external drilling machine 1 is anchored, the side sliding mechanism 6 is operated to make the external drilling machine 1 slide to the side, and after sliding to a certain position, the external drilling machine 1 is operated to anchor the outermost roof anchor rod and anchor cable.

[0036] When the side anchor rod and anchor cable are performed, the external drilling machine 1 is first operated to move forward or sideward to give way to the internal drilling machine 2 until the internal drilling machine 2 is not interfered when rotating, the internal drilling machine 2 is lifted by a certain distance by the lifting oil cylinder 3, the internal drilling machine 2 is rotated by the rotating mechanism 4, the angle anchor rod and anchor cable are anchored after rotating by a certain angle, the anchor rod drilling machine is rotated by the rotating mechanism 4 after the angle anchor rod is anchored, the anchor rod drilling machine is perpendicular to the side, the internal drilling machine 2 is lowered by a certain distance by the lifting oil cylinder 3 to anchor the side anchor rod, the empty side distance of the side anchor rod is reduced, the anchoring of the side is met, and the empty side time and distance are shortened.

[0037] The scheme reduces the empty roof and side distance of tunneling, realizes small hole roof operation, realizes the omnidirectional and dead angle free operation ability of the anchor rod, and can meet the tunneling anchoring process under complex geological conditions.
