Technical Field

[0001] The invention relates to the field of coal mining equipment, and in particular to a reversible drill box for an anchor drill. Background Art

[0002] At present, most coal mines use anchor support technology, using pneumatic or hydraulic anchor drills to construct anchors. Hydraulic anchor drills have the advantages of large torque, high speed, and fast construction speed. They are the mainstream trend of anchor construction equipment in coal mines. However, due to the limited space of coal mine equipment, the anchor drill has a short stroke and cannot drill holes in one construction. It is necessary to carry out joint drilling, that is, a small stroke drilling is carried out once, and the whole drilling is carried out in a second joint drilling. In the existing process, the drill needs to be moved away for joint drilling, which increases the secondary positioning process of the drill, prolongs the drilling operation time, and reduces work efficiency.

[0003] Therefore, the prior art needs to be further developed and improved. Summary of the invention

[0004] In view of the above technical problems, an embodiment of the present invention provides a flip drill box for an anchor drill rig to solve the problem of extending the operation time and reducing the work efficiency due to the insertion of anchor rods in the existing brazing operation.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more centered elements can exist between them. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in this specification and in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] At present, underground anchor support is mostly carried out by hydraulic anchor drilling rigs. Due to the small underground space, the anchor drilling rigs are mostly designed with a smaller feed stroke (generally 1200-1600mm). The length of the underground anchor is generally 2000-2800mm. After the anchor drilling rig completes the drilling, the anchor needs to be inserted into the borehole. Since the anchor drilling rig has a short stroke, it hinders the insertion of the anchor. The anchor drilling rig needs to be moved to one side before the anchor can be inserted. In this process, due to the influence of hydraulic control and mechanical structure, there are deviations in the movement of the drilling rig, and it is cumbersome to find the eye. This greatly affects the efficiency of anchor support. Figure 1The reversible drill box for the anchor drilling rig shown can solve the above problems well. The reversible drill box includes a fixed seat 100 arranged on the slide rail of the anchor drilling rig, a drill box 200 that can be turned relative to the fixed seat, and a turning cylinder 300 that pushes the drill box to turn over. The drill box is connected to the fixed seat through a first hinge shaft 410, one end of the turning cylinder is connected to the drill box through a second hinge shaft 420, and the other end of the turning cylinder is connected to the fixed seat through a third hinge shaft 430. The drill box is driven by the turning cylinder to turn left and right around the first hinge shaft. When the anchor needs to be inserted, the drill box is driven by the turning cylinder to rotate the drill box around the first hinge shaft, so that the output axis of the original drill box moves, thereby ensuring that there is no interference from any mechanism (part) in the axial direction of the drilling hole. The setting of the reversible drill box allows the drill box to be automatically turned over instead of being moved manually before, greatly improving work efficiency. More importantly, the reversible drill box can ensure the accurate turning and returning of the drill box, thereby ensuring the rapid replacement of the anchor of the drilling rig and achieving continuous normal operation of the drilling rig.

[0024] Specifically, Figure 2 As shown, the bottom of the fixing seat is provided with a slot 110 for clamping the bolting machine slide rail. The setting of the slot facilitates the use and fixation of the flip drill box, and the fixing seat is further fixed in position by a fixing pin or screw.

[0025] In a specific embodiment, the top of the piston rod of the flip cylinder is connected to the drill box through the second hinge shaft 420, and the bottom of the flip cylinder is connected to the fixed seat through the third hinge shaft 430. The second hinge shaft is arranged above the first hinge shaft, and the third hinge shaft is arranged below the first hinge shaft. The arrangement of the second hinge shaft and the third hinge shaft enables the flip cylinder to drive the drill box to flip using as little space as possible based on the principle of leverage, so that the drill box can be flipped into place through a smaller cylinder driving stroke, which reduces the size of the device accordingly and facilitates use in the lane.

[0026] Specifically, a connecting ear for fixing the outer cylinder body of the flip cylinder is provided on the outer cylinder body of the flip cylinder. The outer cylinder body is fixed by the connecting ear to ensure the stability of the operation of the flip cylinder.

[0027] In a preferred embodiment, the angle between the axis of the drill box and the first hinge axis and the second hinge axis is 60 degrees. In this way, the drill box can be flipped with the shortest flip cylinder driving stroke, the flip cylinder can push the drill box to move with the minimum thrust, and ensure that the axial direction of the drilling hole is completely unaffected by the drill box.

[0028] Furthermore, the fixing seat is connected to the bottom of the turning cylinder via an articulated base 500, the third articulated shaft is arranged on the articulated base 500, and the articulated base is detachably connected to the fixing seat. By providing a detachable articulated base, it is possible to ensure that the drilling box can replace the turning cylinders of different sizes and types based on the usage scenario, thereby enhancing the use range of the device.

[0029] In a preferred embodiment, Figure 2 As shown, the fixing seat is provided with a pad 120 on the opposite side of the first hinge axis of the drill box. Correspondingly, the drill box is provided with an abutting plane corresponding to the pad. When the drill box is working, the abutting plane of the drill box abuts against the pad. When the drill box is working, a rotation torque centered on the first hinge axis is generated. The pad contacts the abutting plane of the drill box to eliminate the reverse torque, reduce the force on the turning cylinder, and ensure the reliability of the structure.

[0030] In a preferred embodiment, contact sensing probes are respectively embedded on the corresponding surfaces of the abutting plane and the pad, and the contact sensing probes are connected to a buzzer with a controller. The contact sensing probes on the abutting plane and the pad are in contact to form a conductive loop to make the buzzer sound. The buzzer can remind the operator whether the drill box is flipped in place, thereby ensuring the normal use of the drilling rig, avoiding the problem of drilling rig loss and shortened service life caused by abnormal use of the drilling rig, and correspondingly extending the service life of the drilling rig.

[0031] In addition, a guard plate 600 is provided on the side of the fixing seat corresponding to the pad. On the one hand, the guard plate prevents impurities from entering the drill box position and protects the drill box. On the other hand, the guard plate serves as a connecting piece to be connected to an external fixing device, thereby fixing the drill box together with the fixing seat, thereby improving the stability of the drill box operation.

[0032] The present invention provides a reversible drill box for an anchor drill. The device solves the problem that when an anchor drill is used to construct anchors in a small tunnel, the anchor drill does not need to be moved when inserting anchors, solves the problem of low efficiency in replacing drill rods and anchors, makes inserting anchors more convenient, improves anchoring efficiency, reduces secondary eye-finding time, and increases anchor support speed. The device has a simple structure, flexible operation mode, and labor-saving, which is conducive to large-scale promotion.

[0033] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
