Technical Field
[0001] The utility model relates to the technical field of underground mining equipment, in particular to a gantry type machine-mounted drilling and anchoring system. Background Art
[0002] Anchor support is a coal tunnel support method that has developed rapidly in recent years. The construction speed and quality of anchor support depend largely on the anchor drill, which is one of the key technologies affecting the speed, quality and efficiency of anchor support construction. At present, the construction process of using tunneling machines and anchor drills to operate independently can no longer meet the needs of efficient tunneling. The existing device has an integrated design that mounts the anchor drill on the tunneling machine, but the movement range of the anchor drill after being installed on the tunneling machine is very limited, and the position adjustment flexibility of the anchor drill is insufficient during use, which is prone to interference and cannot be applied to tunnel support operations of different sizes and diameters. Utility Model Content
[0003] The purpose of the utility model is to provide a gantry-type airborne drilling and anchoring system, on which a first anchor drilling rig capable of horizontal movement and rotational swinging, and a second anchor drilling rig capable of vertical movement and rotational swinging are arranged. When in use, they will not interfere with each other and their moving range and flexibility meet the requirements. Anchors can be installed at various positions on the top and side surfaces of tunnels of different sizes, solving the problems in the prior art.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] The positive effect of the utility model is that the gantry-type airborne drilling and anchoring system described in the utility model includes a gantry, on one side of the gantry are installed two groups of first anchor drilling rigs that can move and rotate and swing along the length direction of the horizontal beam, and on the other side of the gantry are installed two groups of second anchor drilling rigs that can lift and lower and rotate and swing along the height direction of the vertical beam. The anchor drilling rigs are arranged on the tunneling machine through the gantry, and the movement range on the tunneling machine is significantly improved. The drilling rigs on the gantry can be swung and adjusted, and will not interfere with each other during use. The movement range and flexibility meet the requirements, which solves the problem of too small horizontal and vertical movement distances of the anchor drilling rigs, enhances the applicability to different tunnel widths and heights, and the four groups of anchor drilling rigs can operate independently, which improves the efficiency of anchor support operations in the tunnel to a certain extent.

[0016] The utility model discloses a gantry-type airborne drilling and anchoring system, such as Figure 1-4 As shown, the gantry frame comprises a horizontally arranged crossbeam (1) and vertical beams (2) on both sides of the crossbeam (1). The gantry frame can be arranged on a tunnel boring machine and move together with the tunnel boring machine in the tunnel to perform subsequent anchor bolt installation operations.
[0017] Two groups of first anchor drilling machines (3) are installed on one side of the horizontal beam (1), and each of the first anchor drilling machines (3) can move along the length direction of the horizontal beam (1) and rotate and swing, so that the first anchor drilling machines (3) can install anchor rods at various positions on the top surface of the tunnel. Two groups of second anchor drilling machines (4) are installed on the other side of the horizontal beam (1), and each of the second anchor drilling machines (4) can be lifted and lowered along the height direction of the vertical beam (2) and rotate and swing, so that the second anchor drilling machines (4) can install anchor rods at various positions on the side of the tunnel, wherein the rotation angles of the first anchor drilling machines (3) and the second anchor drilling machines (4) are both ≥90°.
[0018] A longitudinal movement mechanism is installed at the bottom of each vertical beam (2), and the longitudinal movement mechanism and the vertical beam (2) are connected via a swing oil cylinder (32). The piston rod of the swing oil cylinder (32) can be extended and retracted to drive the gantry to swing relative to the longitudinal movement mechanism. The longitudinal movement mechanism can be an existing telescopic cylinder, a moving rod with a driving mechanism such as a motor, or other telescopic moving mechanism, which can drive the vertical beam (2) to move longitudinally.
[0019] In most operating situations, the first anchor drilling rig (3) and the second anchor drilling rig (4) can realize anchor support at various positions on the top and side of the tunnel, and are suitable for tunnels of different sizes and types. Each anchor drilling rig can adjust the operation independently, which improves the efficiency of anchor support operations in the tunnel to a certain extent. The lateral movement of the first anchor drilling rig (3) and the vertical movement of the second anchor drilling rig (4) can be achieved by a drive mechanism such as a telescopic cylinder or a motor, and its own rotation can be achieved by a slewing support and a slewing motor. In specific demand situations, for example, two groups of first anchor drilling rigs (3) and second anchor drilling rigs (4) need to be anchored to the top of the tunnel, and two groups of first anchor drilling rigs (3) and second anchor drilling rigs (4) need to be anchored to the side of the tunnel. The first anchor drilling rig (3) can also install anchors on the side of the tunnel, and the second anchor drilling rig (4) can also install anchors on the top of the tunnel, and the respective movements and drilling rod movements of the two anchor drilling rigs will not interfere with each other.
[0020] In order to realize the installation of the first anchor drilling machine (3) on the cross beam (1), as well as the lateral movement along the length direction of the cross beam (1) and the relative rotation thereof, a lateral movement slide plate (5) is installed on one side of the cross beam (1), the lateral movement slide plate (5) can move laterally relative to the cross beam (1), a rotatable first rotating disk (6) is installed on the lateral movement slide plate (5), a first rotating seat (7) is arranged on the first rotating disk (6), and the first anchor drilling machine (3) is fixedly installed on the first rotating seat (7). A first rotating oil cylinder (8) is hingedly installed between the lateral movement slide plate (5) and the first rotating disk (6), and the extension and retraction of the piston rod of the first rotating oil cylinder (8) can drive the first anchor drilling machine (3) to rotate and swing relative to the lateral movement slide plate (5).
[0021] like Figure 5 As shown, one side of the crossbeam (1) is provided with a transverse slide rail (9) and a rack (10) arranged along the length direction, and a sliding block (11) matched with the transverse slide rail (9) is installed on the transverse slide plate (5). A rotary reducer (12) is also provided on the transverse slide plate (5), and a gear (13 meshing with the rack (10) is installed on the output shaft of the rotary reducer (12). The rotary reducer (12) can drive the transverse slide plate (5) and the first anchor drilling rig (3) thereon to move horizontally.
[0022] By rotating the first anchor drill (3) itself and moving horizontally in the length direction of the crossbeam (1), vertical anchor bolt or inclined anchor bolt support operations can be performed at various positions on the top of the tunnel during the movement of the tunnel boring machine.
[0023] In order to realize the installation of the second anchor drilling machine (4) on the gantry, as well as the vertical movement along the height direction of the vertical beam (2) and the relative rotation thereof, a vertical movement slide plate (14) is installed on the other side of the horizontal beam (1), and the vertical movement slide plate (14) can be vertically lifted and lowered relative to the horizontal beam (1). A rotatable second rotating disk (15) is installed on the vertical movement slide plate (14), and a second rotating seat (16) is arranged on the second rotating disk (15), and the second anchor drilling machine (4) is fixedly installed on the second rotating seat (16). A second rotating oil cylinder (17) is hingedly installed between the vertical movement slide plate (14) and the second rotating seat (16), and the extension and retraction of the piston rod of the second rotating oil cylinder (17) can drive the second anchor drilling machine (4) to rotate and swing relative to the vertical movement slide plate (14).
[0024] like Figure 6 As shown, a vertical slide rail (18) and a lifting cylinder (19) are provided on one side of the vertical beam (2), a vertical slide block (20) matched with the vertical slide rail (18) is installed on the vertical slide plate (14), and the piston rod of the lifting cylinder (19) is connected to the vertical slide plate (14), and the piston rod of the lifting cylinder (19) can drive the vertical slide plate (14) and the second anchor drilling rig (4) thereon to rise and fall vertically. A hydraulic cylinder-chain multiple-speed feeding mechanism can be formed between the piston rod of the lifting cylinder (19) and the vertical slide plate (14) by adding mechanisms such as chains and rollers, so that a large vertical movement of the vertical slide plate (14) can be achieved by a small vertical lifting of the lifting cylinder (19) within a small space.
[0025] By rotating the second anchor drill (4) itself and moving vertically in the height direction of the vertical beam (2), vertical anchor or inclined anchor support operations can be performed at various positions on both sides of the tunnel during the travel of the tunnel boring machine.
[0026] The first anchor drilling rig (3) and the second anchor drilling rig (4) expand the range of anchor drilling that can be performed, and each anchor drilling rig can rotate by an angle of ≥90°, so that the anchor drilling rig can be switched between horizontal and vertical angles.
[0027] In order to realize the longitudinal movement of the gantry with the anchor drilling rig on the tunnel boring machine, the stable connection and longitudinal telescopic movement on the tunnel boring machine are required. Figure 7 and Figure 8As shown, the longitudinal movement mechanism comprises a fixed outer cylinder (21), the fixed outer cylinder (21) is arranged on both sides of the tunnel boring machine, a telescopic middle cylinder (22) is installed in the fixed outer cylinder (21), a telescopic inner cylinder (23) is installed in the telescopic middle cylinder (22), and a gantry is installed at the front end of the telescopic inner cylinder (23). A first longitudinal movement cylinder (24) is installed between the fixed outer cylinder (21) and the telescopic middle cylinder (22), and a second longitudinal movement cylinder (25) is installed between the telescopic middle cylinder (22) and the telescopic inner cylinder (23). The longitudinal movement of the gantry relative to the tunnel boring machine can be achieved by telescoping the piston rods of the first longitudinal movement cylinder (24) and the second longitudinal movement cylinder (25), thereby adaptively adjusting the anchor drilling position in the tunnel.
[0028] Furthermore, in order to improve the installation strength of the fixed outer cylinder (21) on the tunnel boring machine, a protective plate (26) is provided on the inner side of the fixed outer cylinder (21). In order to realize the installation and positioning of the first longitudinal displacement cylinder (24), a plurality of side-by-side arranged limiting plates (27) are provided on the upper side of the fixed outer cylinder (21). Each limiting plate (27) is provided with a through hole, and the cylinder barrel of the first longitudinal displacement cylinder (24) is located in the through hole of the limiting plate (27).
[0029] In the above structure, the first longitudinal movement cylinder (24) is arranged at the outer side of the fixed outer cylinder (21). Compared with the structure in which the moving cylinder is arranged inside the cylinder, the volume of the fixed outer cylinder (21) can be effectively reduced, the material used for the components can be reduced, and the structural strength can be improved, the weight of the moving mechanism required for longitudinal movement can be reduced, and the input of power during longitudinal movement can be reduced. The cylinder barrel of the first longitudinal movement cylinder (24) is positioned and arranged inside the limit plate (27), and the piston rod of the first longitudinal movement cylinder (24) is fixedly connected to the end position of the telescopic middle cylinder (22) through the reinforcing rib plate. The setting of the limit plate (27) not only provides installation positioning for the first longitudinal movement cylinder (24), so that when the piston rod of the first longitudinal movement cylinder (24) is extended or retracted, the telescopic middle cylinder (22) can smoothly perform longitudinal movement and guided extension and retraction at the set position relative to the fixed outer cylinder (21), but also can improve the connection strength between the fixed outer cylinder (21) and the guard plate (26) to a certain extent. Furthermore, the first longitudinal movement cylinder (24) located at the outer position allows the operator to have a more intuitive perception of the longitudinal movement and telescopic distance of the overall structure, and facilitates the inspection and maintenance of the first longitudinal movement cylinder (24).
[0030] In order to improve the support stability of the lifting device when performing anchor support operations at the top position in the tunnel, a vertical support cylinder (28) is installed on the front side of the vertical beam (2), the piston rod of the vertical support cylinder (28) is downward and is installed with a support foot, and in order to realize the vertical lifting of the overall gantry, a vertical displacement lifting cylinder (29) is installed in the vertical beam (2). A swing cylinder (30) is installed on the outer periphery of the vertical support cylinder (28) and the vertical displacement lifting cylinder (29), and a reinforcing plate (31) is provided at the end of the telescopic inner cylinder (23). The reinforcing plate (31) and the swing cylinder (30) are hingedly connected through a rotating shaft. A swing oil cylinder (32) is also installed between the reinforcing plate (31) and the swing cylinder (30). The piston rod of the swing oil cylinder (32) can drive the gantry to swing and adjust relative to the longitudinal movement mechanism, that is, adjust the pitch angle position of the overall gantry on the tunneling machine, so that the position adjustment of the anchor drilling machine is more flexible, thereby realizing the anchor fixing operation at various positions in the tunnel.
[0031] Furthermore, if Fig.10 As shown, a supporting square tube (40) is installed in the vertical beam (2), the diameter of the supporting square tube (40) is smaller than the diameter of the vertical beam (2), the vertical beam (2) is sleeved on the outer circumference of the supporting square tube (40), and the vertical beam (2) is located on the upper part of the supporting square tube (40). A vertical displacement lifting cylinder (29) is installed in the supporting square tube (40), wherein the cylinder barrel of the vertical displacement lifting cylinder (29) is hinged in the supporting square tube (40), the piston rod of the vertical displacement lifting cylinder (29) is hinged at the top position of the vertical beam (2), the supporting square tube (40) extends out of the lower end of the vertical beam (2) and is connected to the swing tube (30), and the extension of the piston rod of the vertical displacement lifting cylinder (29) can drive the vertical beam (2) to move vertically upward along the supporting square tube (40).
[0032] The arrangement of the above-mentioned structure can realize the vertical lifting of the vertical beam (2), and because a vertical sliding rail (18) needs to be arranged on the vertical beam (2) to realize the vertical movement of the anchor drilling rig, the vertical beam (2) is set on the outer periphery of the supporting square tube (40). When the vertical beam (2) is vertically lifted, the sliding rail installed on the outer side thereof will not interfere with the internal supporting square tube (40). While realizing the vertical movement of the vertical beam (2) and the gantry, it will not affect the movement and adjustment of the anchor drilling rigs on the gantry, thereby greatly improving the flexibility of the adjustment of the anchor drilling rig.
[0033] Furthermore, in order to facilitate the maintenance or auxiliary work of the staff on the gantry, a fixed pipe (33) is provided on the front side of the vertical beam (2), and both sides of the fixed pipe (33) are hingedly installed with an operating platform plate (34) that can be rotated and opened, and the staff can stand on the operating platform plate (34) to perform auxiliary operations. In order to improve the stability of the side anchor support of the tunnel, side protection cylinders (35) are installed at both ends of the length direction of the crossbeam (1), and the piston rods of the side protection cylinders (35) can be extended to support the walls on both sides of the tunnel, thereby improving the stability of the overall device in the tunnel, solving the problem that the second anchor drilling machine (4) is prone to horizontal vibration when working, and enhancing the stability of the gantry type hydraulic drilling and anchoring system when working.
[0034] Furthermore, a support mechanism is installed on the upper part of the crossbeam (1), and the support mechanism can receive fallen rocks and soil blocks from the top during the excavation process to prevent the falling rocks and soil blocks from causing damage to the devices at the bottom. Fig. 9 As shown, the support mechanism includes support vertical pipes (36) arranged side by side, support cylinders (37) are installed in the support vertical pipes (36), a support main frame (38) is hingedly installed on the piston rod of the support cylinder (37), and flippable support side frames (39) are hingedly installed on both sides of the support main frame (38). The support cylinder (37) can drive the support main frame (38) to perform vertical lifting and adjustment, and the support side frames (39) on both sides can increase the falling object receiving range of the entire support mechanism, thereby providing more comprehensive protection for the various mechanisms at the bottom.
