DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will provide a clear and complete description of the technical solution of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary skilled persons in the art without creative labor are within the scope of protection of the present disclosure.

[0032] In the description of the present disclosure, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be broadly understood, for example, they can be fixed connections, detachable connections, or integral connections; It can be a mechanical connection or an electrical connection; It can be directly connected, indirectly connected through an intermediate medium, or connected internally between two components. For ordinary technical personnel in this field, the specific meanings of the above terms in the present disclosure can be understood in specific situations.

[0033] In addition, the technical features involved in different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0034] Referring to FIG. 1 to FIG. 22, as a preferred embodiment of the present disclosure, the embodiment provides a multifunctional drilling and blasting integrated trolley device. The device includes a steel arch frame 10 and a plurality of motor-driven crawler traveling mechanisms 20 connected to a bottom of the steel arch frame 10. The steel arch frame 10 includes a front arch beam 11, a rear arch beam 12, and an upper cross beam 13 and a bottom beam 14 that are connected to the front arch beam and the rear arch beam. The front and rear arch beams are of similarly H-shaped cross-section structures. The steel arch frame 10 in the present disclosure is an appropriate steel arch frame designed based on a hole size of a tunnel. The device further includes a plurality of groups of drilling and explosive conveying devices 30. The drilling and explosive conveying device 30 includes a guide rod 31 disposed parallel to the upper cross beam 13. Two ends of the guide rod 31 are connected to guide rod wheels 32. The guide rod wheel may be circular, or may be polygonal. A plurality of first magnetic suction plates 33 are disposed on a wheel circumference of the guide rod wheel 32 at intervals. The guide rod wheel 32 is magnetically connected to a first magnetic guide rail 15 disposed on the front arch beam 11 and the rear arch beam 12. The magnetic guide rail is disposed on the circumferential direction of the front arch beam and the rear arch beam. A plurality of first contact points 16 are disposed adapted to the first magnetic suction plate 33 on the first magnetic guide rail 15 at intervals. When the plurality of first contact points 16 are controlled to be powered on or powered off, the powered-on first contact points 16 are attracted with the first magnetic suction plate 33, and the powered-off first contact points and the first magnetic suction plate 33 are free of suction to realize movement of the guide rod wheel 32 on the first magnetic guide rail 15. The guide rod 31 is connected to a drill rod slot 34 by using a bearing. A main arm 35 is hinged into the drill rod slot 34. An end of the main arm 35 is hinged to an auxiliary arm 36. A luffing cylinder 37 is hinged between the main arm 35 and the auxiliary arm 36. An end of the auxiliary arm 36 is hinged to a saddle 38. A luffing cylinder is further hinged between the saddle 38 and the auxiliary arm 36. A drilling device 40 and a charging device 50 are connected to the saddle 38. A luffing cylinder is hinged between a middle part of the main arm 35 and the drill rod slot 34. The luffing cylinders are all hydraulic cylinders. The luffing cylinder between the middle part of the main arm 35 and the drill rod slot 34 drives the main arm 35 to perform a luffing motion around a hinge point of the drill rod slot 34 and the drill rod slot 34.

[0035] As shown in FIG. 8 to FIG. 12, the hinge point is fixedly disposed in the guide rod slot 34 to connect to the main arm 35. In addition, the disposed hinge point is connected to the luffing cylinder 37 to be capable of driving the main arm 35 to perform the luffing motion. The auxiliary arm 36 is hinged and connected to the other end of the main arm 35. The auxiliary arm 36 is driven to perform the luffing motion around the hinge point at the end of the main arm by using the luffing cylinder between the main arm 35 and the auxiliary arm 36. The other end of the auxiliary arm 36 is connected to the saddle 38 by using the hinge point. The saddle 38 is driven to perform the luffing motion by using the luffing cylinder between the auxiliary arm 36 and the saddle 38.

[0036] As shown in FIG. 9, the saddle 38 is preferably of an arc-shaped structure, and a circle center axis of the arc-shaped structure of the saddle 38 is parallel to an axis of the guide rod 31. In this way, a radius of the circle center axis of the guide rod 31 may be kept unchanged when rotating around the guide rod 31, so that charging of explosive can be implemented by swinging a small angle after drilling is completed. A distance with the axis of the guide rod 31 is not adjusted by using the luffing cylinder between the main arm 35 and the auxiliary arm 36, thereby simplifying operation and fully improving efficiency.

[0037] When in use, the main arm 35 and the auxiliary arm 36 may be retracted from the drill rod slot 34 in a non-working state by folding of each luffing cylinder, thereby avoiding structural damage while effectively utilizing space.

[0038] In some preferred embodiments, as shown in FIG. 10 and FIG. 11, the guide rod wheel 32 is connected to a wheel frame 48. A first side blocking wheel 49 is further connected to the wheel frame 48. The first side blocking wheel is configured to abut against two side plates of the first magnetic guide rail 15, so as to limit a motion trail of the guide rod wheel.

[0039] In the present disclosure, under the action of a control program, the first contact points 16 in a forward direction to the guide rod wheel 32 are continuously powered on by using the first magnetic guide rail 15. When the previous first contact is powered on, the first contact point away from the forward direction is randomly powered off randomly while the previous first contact point is powered on. The first contact point that is powered on is attracted with the first magnetic plate 33 on the guide rod wheel 32, so that the guide rod wheel 32 can be driven to move in the forward direction. When the powered-on first contact point is converted quickly forward, the guide wheel runs fast. When powered-on first contact point is converted slowly, the guide rod wheel runs slowly. A motion in the reverse direction is in a similar way. The side blocking wheels 49 on two sides of the guide rod wheel 32 are fixed to the position of the wheel frame 48, and slidably make contact with the side plates of the front arch frame 11 and the rear arch frame 12 to ensure that the position of the guide rod wheel 32 is directly above the contact point, so that the first contact point is accurately aligned with the first magnetic suction plate, and suction can be well achieved. Further, it is ensured that the guide rod wheel 32 moves stably on the first magnetic guide rail 15. When the guide rod wheel 32 needs to be brake or stops at a position, no on-off change is performed at magnetic point points under program control, and the first contact point corresponding to the guide rod wheel 32 is kept to be powered on.

[0040] Each first magnetic guide rail can accurately position a corresponding working mechanism under information acquisition of a control system and the control program based on specific positions of suction points of the contact points on the first magnetic suction plate with the guide rod, the traveling wheel, and the like, so as to implement precision and automated work.

[0041] Specifically, as shown in FIG. 10 and FIG. 14, the drilling device 40 includes a drilling rig sleeve 41. A drilling rig 42 is disposed in the drilling rig sleeve 41. The bottom of the drilling rig 42 is connected to a drilling rig wheel 43. A plurality of second magnetic suction plates are connected in a circumferential direction of the drilling jig wheel 43 at intervals. A second magnetic guide rail is further disposed at the bottom of the drilling rig sleeve 41. A plurality of second contact points are arranged adapted to the second magnetic suction plate on the second magnetic guide rail at intervals. When the plurality of second contacts are powered on or powered off, the powered-on second contact points are attracted with the magnetic suction plate to realize movement of the drilling jig wheel on the second magnetic guide rail. Here, a working principle of the second magnetic guide rail is similar to that of the first magnetic guide rail on the front arch beam and the rear arch beam. Under a combined action of the second magnetic guide rail and the drilling rig wheel 43 disposed at a lower part of the drilling rig, the drilling rig 42 may move forward and back along the drilling rig sleeve 41.

[0042] In some embodiments, a positioning wheel 44 is further disposed in the drilling rig sleeve 41. The positioning wheel 44 abuts against the drilling jig 42. A plurality of positioning wheels 44 are fixedly disposed on a top surface inside the drilling rig sleeve 41 so as to facilitate positioning and stability of the drilling rig 42 when moving forward and back inside the drilling rig sleeve 41. The drilling rig 42 is driven by a motor to rotate so as to perform a drilling operation on a rock surface. During the drilling operation, a plurality of drilling rig wheels 43 disposed at the lower part of the drilling rig 42 are simultaneously sucked to ensure stability during the drilling operation.

[0043] Specifically, as shown in FIG. 10 and FIG. 13, the charging device 50 includes a charging cylinder 51 and an explosive bag 52 disposed in the charging cylinder. One end inside the charging cylinder 51 is connected to a reset spring 53. The other end of the reset spring 53 is fixedly connected to a plug plate 54. A suction cup 55 is disposed at one end of the explosive bag 52. The suction cup 55 is adsorbed with and connected to the plug plate 54. An inflation port 56 is formed in one end of the charging cylinder 51. The inflation port 56 is connected to a pressure relief valve 57. The inflation port 56 is configured to inflate air in the charging cylinder 51 so that the explosive bag 52 is moved towards a target direction after the plug plate 54 is pushed. The pressure relief valve 57 is configured to leak air for the charging cylinder 51 so that the plug plate 54 is reset under an elastic action of the reset spring 53 after charging is completed.

[0044] When drilling is completed, explosive needs to be filled. Under program control, based on a distance between an axis of the drilling jig 42 and an axis of the guide rod 31, the program automatically calculates an angle value that needs to be rotated, and the adjusting motor 47 drives an adjusting gear to drive the drill rod slot 34 and an upper structure thereof to deflect at a small angle. In this way, it can be ensured that a tube port of the charging cylinder 51 directly faces a port in which needs the explosive to be filled. The explosive bag 52 is packed in the charging cylinder 51 in advance. A tail of the explosive bag 52 and the suction cup 55 fixedly disposed on the plug plate 54 are sucked with negative pressure after jacking and air extrusion to fix the explosive bag 52. A link of pushing the explosive bag 52 into the hole is needed. Air is inflated into a plug cylinder through the inflation port 56 by using an air supply pipe. The plug plate 54 is pushed to move forward. The explosive bag 52 enters into the hole under the guide of the charging cylinder 51. When the suction cup 55 needs to be detached from the explosive bag 52, the adjusting gear 46 and the fixed gear 39 are driven to rotate at a small angle to implement detachment, and then the pressure relief valve 57 relieves pressure. The plug plate 54 can be retracted and reset under the action of the reset spring 53 to be put in the explosive bag again to repeat a working cycle. The magnetic rails and the plurality of groups of drilling devices and charging devices are disposed in upward directions and downward directions of the front arch beam and the rear arch beam of the steel arch frame, so that each group of drilling devices and charging devices can work simultaneously to ensure maximum efficiency. The control program automatically distributes work holes based on a blasting design of an excavation surface, thereby efficiently implementing a drilling operation and a charging operation.

[0045] In some preferred embodiments, the saddle 38 is an arched plate, and the drilling device 40 and the charging device 50 are disposed on the saddle in parallel.

[0046] In some preferred embodiments, an axis of the saddle is parallel to an axis of the guide rod, so that the drilling device 40 and the charging device 50 are facilitated to be adjusted preferably.

[0047] In some preferred embodiments, as shown in FIG. 1 to FIG. 4, the device further includes support shoe devices 60 disposed on two sides and a rear side of the steel arch frame 10, and the support shoe devices 60 are configured to abut against a side wall or ground of a tunnel during a drilling operation or a charging operation to provide reaction force to ensure stability of the operation.

[0048] Specifically, as shown in FIG 1 and FIG. 16, the support shoe device 60 includes a support arm 61 hinged to the steel arch frame 10. An end of the support arm 51 is hinged to a support plate 62. A luffing cylinder is hinged between the support arm 61 and the steel arch frame 10. A drag plate 63 and a magnetic suction plate 65 are connected to a bottom of the support plate 62. A wedge pin 64 is further disposed at one end of the support plate 62.

[0049] A plurality of support shoe devices 60 are disposed on two sides and at the back of the steel arch frame 10, so that when the steel arch frame 10 performs drilling and other operations, support shoes can abut against the ground to provide better stability for the steel arch frame 10. The support shoe device 60 on a side surface abuts against the ground or a side wall, and the support shoe device at the back abuts against the ground. The support shoe devices on the side surface or at the back are basically the same in structures. A drag plate 63 of a wearable and soft material is disposed on a bottom surface of the support plate 62. The support plate 62 is further provided with a support shoe magnetic suction plate 65. One end is further provided with the wedge pin 64 in a support. For example, when the ground is concrete or hard non-metallic ground, the drag plate 63 can provide support force for the steel arch frame 10 by using extrusion force with the ground. For example, when the ground is ground of a metal material, the support shoe magnetic suction plate 65 is powered on to generate suction force, and is firmly attracted with the metal ground, which can provide support force for the steel arch frame 10. For example, the ground is soft muddy or gravelly ground. On one hand, the drag plate 63 is tightened, and on the other hand, after the wedge pin 64 is wedged into the ground, support force is provided for the steel arch frame 10 jointly.

[0050] In some preferred embodiments, as shown in FIG. 3 and FIG. 6, the device further includes an explosive networking and inspection device 70. The explosive networking and inspection device 70 is used for an operator to perform explosive networking and inspection at a plurality of blasting points. The explosive networking and inspection device 70 includes a magnetic tape track 71 and a basket vertical plate 72 disposed on the front arch beam 11. A traveling wheel 73 is disposed on the basket vertical plate 72. A plurality of third magnetic suction plates are disposed on a wheel circumference of the traveling wheel 73 at intervals. The traveling wheel 73 is magnetically connected to the magnetic tape track 71. The basket vertical plate 72 is L-shaped. A star wheel motor 74 is disposed at the bottom of the basket vertical plate 72. A driving gear 77 is connected to the star wheel motor 74. A work basket 75 is further slidably disposed on the basket vertical plate 72 by using a horizontal track. A rack 76 meshed with the driving gear 77 is disposed at the bottom of the work basket 75.

[0051] Explosive networking and inspection are fine tasks, and are only suitable for manual operation and completion. In the explosive networking and inspection device 70, working principles, working manners, and operation and stopping working principles of the traveling wheel 73 and the magnetic tape track 71 are exactly the same as those of the guide rod wheel 32 on the guide rod 31 and the first magnetic guide rail 15. Details are not described herein again.

[0052] In some embodiments, second side blocking wheels are disposed on two sides of the traveling wheel 73, and the second side blocking wheels are configured to abut against two side plates of the magnetic tape track to limit motion trails of the traveling wheel.

[0053] In some preferred embodiments, as shown in FIG. 3, FIG. 6 and FIG. 7, the magnetic tape track 71 and the basket vertical plate 72 are disposed on the two parallel front arch beams 11. The work basket includes a left basket 75-1, a middle basket 75-2 and a right basket 75-3. The middle basket 75-2 is slidably connected between the left basket 75-1 and the right basket 75-3 by using guide rails. The rack 76 is disposed at the bottoms of the left basket 75-1 and the right basket 75-3.

[0054] In this embodiment, the work basket is a retractable multi-segment structure, so that length extension of the work basket 75 can be realized. Length extension and contraction of the work basket 75 may be adapted to a change of a tunnel width and a requirement of avoiding a barrier in the tunnel, thereby further improving adaptability of the device in the present disclosure. A cross-section size of the middle basket 75-2 is slightly smaller than those of the left basket 75-1 and the right basket 75-3. Preferably, three guide wheels are disposed on two sides and at the bottom of the middle basket 75-2 on a same motion section, and left and right ends of the middle basket 75-2 are additionally respectively provided with one motion section. Three guide wheel slots are formed in corresponding positions inside the left basket 75-1 and the right basket 75-3, so that the guide wheels can roll in the guide wheel slots, namely, the effect that the middle basket can telescopically slide inside the left basket 75-1 and the right basket 75-3 at both ends can be realized. A control cabinet is further disposed on the work basket, so that the personnel can operate telescoping and integral up-and-down movement of the work basket on a hanging basket. Preferably, a motor-driven star wheel is used at the bottoms of the left basket 75-1 and the right basket 75-3, and the star wheel drives the left basket 75-1 and the right basket 75-3 to move towards the middle basket 75-2 in the middle by driving the rack at the bottom of the side basket, so that integral length shortening of the hanging basket can be realized. On the contrary, if the left basket 75-1 and the right basket 75-3 move towards a direction away from the middle basket under the action of a driving device at the bottom, integral length elongation of the hanging basket can be realized.

[0055] When all burst holes in an excavation face have been blasted, after all charging cylinders 51 are charged and disengaged from the explosive bag 52, an operator enters the work basket 75 to perform position control by using the control cabinet on the work basket 75. A detonator is installed for explosive, and testing is performed after networking, that is, all preparation work before blasting is completed.

[0056] In some preferred embodiments, as shown in FIG. 1, flange adjusting mechanisms 80 are disposed at the bottoms of the front arch beam 11 and the rear arch beam 12.

[0057] Specifically, as shown in FIG. 5, in order to ensure that integral inclination caused by the fact that the traveling wheel encounters obstacles when the device in the present disclosure is in operation further possibly causes a risk of falling. The flange adjusting mechanism 80 is disposed at lower parts of four main beams in the vertical direction. The flange adjusting mechanism 80 includes an upper flange 81 connected to the bottoms of the front arch beam 11 and the rear arch beam 12, and a lower flange 82 connected to the top of the crawler traveling mechanism 20. The upper flange 81 and the lower flange 82 are inserted with a wedge block 83. Adjusting oil cylinders are disposed in the front arch beam 11 and the rear arch beam 12. A spirit level is disposed on the upper cross beam 13.

[0058] An outer flange of the main beam penetrates into a pin hole of the flange by using the wedge block 83 with an upper wide part and a lower narrow part. A plurality of wedge blocks 83 and a plurality of pin holes are disposed on a circumference of each flange. The adjusting oil cylinder is further disposed inside the main beam. The device in the present disclosure is used in an environment inside holes or at other excavation construction areas. A road surface in this working environment is often a non-pouring forming road, and a road condition is often poor. In a walking process of the steel arch frame, a side encounters earth and stone fallen from a vehicle, a slope, or a pit, and levelness of the top surface of the steel arch frame may be caused to be out-of-tolerance, which may lead to unnormal traveling, and even cause device tilting. Therefore, a level meter is disposed on a surface of the horizontal beam, which may feed back a deviation condition to a control system. When the deviation is out-of-tolerance in an allowance range, the control system does not perform action control. However, once the levelness is out-of-tolerance, the control system immediately and automatically performs elongation adjustment on the adjusting oil cylinder inside the main beam needing to be adjusted after calculation. The corresponding flange may also become into an open state from a closed state. To avoid flange dislocation after the adjusting oil cylinder is retracted, the wedge block 83 and the pin hole are formed. The upper flange also drives the wedge block 83 to move upward in an upward movement process under the driving of the adjusting oil cylinder. When the adjusting oil cylinder is reset, the upper flange is also returned to be attached to the lower flange, and the wedge block 83 can play a role in guiding and promoting correct reset.

[0059] In addition, a main beam shaft is connected to a lower end of the main beam, and the main beam shaft extends into a traveling column of an upper part of the traveling wheel. The main beam shaft and the traveling column are connected through relative movement of a side bearing and a bottom bearing.

[0060] In traveling and walking working conditions of the steel arch frame, for example, the conditions that the steel arch frame travels to the excavation surface before excavation or avoids the gun before blasting belong to such working conditions, but are not limited to these working conditions. The levelness can be automatically or manually adjusted based on levelness data measured by the system.

[0063] In some preferred embodiments, as shown in FIG. 1 and FIG. 5, in order to facilitate the function of local position adjustment or even steering in a narrow space such as in a hole, the reverse gear 27 and the ring gear 24 are preferably helical gears and helical gear rings, and the reverse gear 27 driven by the steering motor 26 on the connecting plate 25 at the bottom end of the main beam is meshed with the ring gear 24 to drive the crawler traveling mechanism to adjust the direction or even steer.

[0064] In the present disclosure, a lower part of the steel arch frame preferably has a crawler-type traveling mode, so as to better adapt to an uneven walking condition of roads inside and outside the tunnel. The mode can not only adapt to the uneven situation on one side, but also realize the independent or integral direction adjustment or steering of a single crawler traveling wheel.

[0065] In some preferred embodiments, the crawler traveling mechanism is used as a common traveling mechanism in engineering machinery. Further, a drive wheel driven by a motor is connected to an upper part of a structure plate inside the crawler traveling wheel, and a follower wheel is further disposed at another end of the internal structure plate.

[0066] In addition, the traveling mechanism can be in the form of crawler, and various suitable ways such as tire type and spiral wheel can also be selected.

[0067] In some preferred embodiments, as shown in FIG. 12 and FIG. 13, a fixed gear 39 is further disposed on the guide rod 31. The bottom of the drill rod slot 34 is connected to an adjusting gear 46 meshed with the fixed gear 39 by using a fixed rod 45.

[0068] A supporting point of the drill rod slot 34 is connected to the guide rod 31 through the bearing. An upper structure of the supporting point cannot slide on the guide rod 31, but can rotate around the guide rod 31. A lower part of one end of the drill rod slot drives the adjusting gear 46 by using the adjusting motor 47 to perform an meshed motion with the fixed gear 39 fixedly disposed on the guide rod 31. Under the meshed motion of the adjusting gear 46 driven by the adjusting motor 47, the drill rod slot 34 and an upper structure thereof rotate around the guide rod 31 through two supporting points.
