[0002] At present, the mechanization level of coal mine driving faces in China is relatively low. In driving faces, a roadheader and a pneumatic bolt drill are still mostly used for driving and support operations respectively. This process has high labor intensity, poor safety and low efficiency. To improve the mechanization level of driving faces, in recent years, domestic vertical-axis roadheader-anchoring machines and horizontal-axis roadheader-anchoring machines have been developed. Among them, the vertical-axis roadheader-anchoring machine is equipped with an on-board bolt drill for support operations, but there are problems such as insufficient number of drill arms and slow positioning speed, and it cannot significantly improve the driving speed and efficiency. In addition, with the increasingly complex coal mine geological conditions in China, there is a new demand for long-distance exploration holes. Existing driving equipment usually only has the capabilities of driving and bolt support, and cannot realize the advance detection of the unexcavated area in front during the driving process, and cannot adjust the driving direction and driving speed according to the actual geological conditions, bringing various degrees of trouble to the driving work.

[0023] A multi-drill gantry tunneling, bolting and exploration integrated machine according to the present utility model, as Figures 1 - 3 shown, includes a frame 1, on which a crawler traveling mechanism 10 and a tunneling mechanism 11 are installed. The crawler traveling mechanism 10 is the traveling mechanism of the whole machine, which can be an existing crawler vehicle or other traveling devices with crawlers and pulleys. The tunneling mechanism 11 includes a rotatable cutting head 12 and a material conveyor belt 13. One end of the material conveyor belt 13 is located below the cutting head 12, and the other end of the material conveyor belt 13 is located at the rear of the frame 1. The rotation of the cutting head 12 can realize the opening excavation in the roadway, and the materials such as stones dropped during the excavation process can be conveyed by the material conveyor belt 13 outside the roadway to avoid interference with the tunneling, so as to facilitate the continuation of the tunneling. A swingable scraper plate mechanism 2 is installed at the front end of the frame 1, which can collect and convey the soil and stone dropped on the ground, so as to facilitate the movement of the whole machine in the roadway after tunneling.

[0024] To realize the stable anchoring support of the multi-drill gantry tunneling, bolting and exploration integrated machine in the roadway, a gantry multi-drill arm support system 3 is installed on the upper side of the tunneling mechanism 11. The gantry multi-drill arm support system 3 is installed on the frame 1 through an elastic lifting mechanism 4. The gantry multi-drill arm support system 3 can perform vertical lifting, horizontal telescoping and deflection angle adjustment relative to the frame 1 to adapt to roadways with different cross-sectional shapes. A number of anchor drill rigs are installed on the gantry multi-drill arm support system 3, which can make the whole machine form a more stable anchoring support in the roadway.

[0025] Among them, the gantry multi-boom support system 3 may include a gantry frame or a gantry-type frame structure, and corresponding support structures and anchoring drills are installed on the gantry frame and the gantry-type frame. The elastic lifting mechanism 4 may be a vertical movement mechanism with elastic deformation or a moving mechanism with an elastic guiding device. While realizing the installation function with the frame 1, it does not limit the relative position between the gantry multi-boom support system 3 and the frame 1, enabling the anchoring drills on the gantry multi-boom support system 3 to adaptively drill and anchor for support according to the actual roadway section shape, thereby improving the support stability of the whole machine in the roadway.

[0026] In order to formulate the subsequent excavation route and direction according to the actual geological conditions at the excavation position, a forward exploration drill system 5 is also installed at the front end of the frame 1. The forward exploration drill system 5 can perform long-distance drilling detection on the unexcavated position. Based on the actual geological conditions obtained from the detection, the staff can formulate a more favorable subsequent excavation plan.

[0027] The crawler travel mechanism 10 in the above multi-boom roadheader-anchor-explorer can drive the whole machine to travel in the roadway. The cutting head 12 in the tunneling mechanism 11 can excavate the roadway. The scraper plate mechanism 2 can shovel and collect the materials falling during the excavation process and convey and transfer them through the material conveyor belt 13. Under the telescopic control of the elastic lifting mechanism 4, the gantry multi-boom support system 3 can adaptively anchor and support the inner peripheral wall of the roadway.

[0028] Further, as Figures 4 - 7 shown, the gantry multi-boom support system 3 includes two sets of telescopic outer beams 30 arranged side by side. The telescopic outer beams 30 are arranged along the length direction of the whole machine and are located at the upper positions on both sides of the whole. A telescopic inner beam 31 is installed in each telescopic outer beam 30 in a matching manner. A telescopic cylinder 32 is installed between the telescopic inner beam 31 and the telescopic outer beam 30. Through the drive of the telescopic cylinder 32, the telescopic inner beam 31 can move relative to the telescopic outer beam 30 to complete the forward extension of the whole gantry multi-boom support system 3 to cover and support the front cutting head 12 of the whole machine.

[0029] Cross beams 33 are installed at the ends of the two sets of telescopic inner beams 31. Drill fixing seats 34 are provided at both ends in the length direction of the cross beams 33. The cross beams 33 and the drill fixing seats 34 form a gantry structure at the front end position of the gantry multi-boom support system 3. Among them, a top beam 35 is installed between the two sets of telescopic outer beams 30. The top beam 35 is installed on the frame 1 through the elastic lifting mechanism 4, thereby realizing the multi-angle position movement of the gantry multi-boom support system 3 relative to the frame 1.

[0030] A number of horizontally movable and rotatable cable bolt drills 36 are installed on the sides of the roof beam 35 between the telescopic outer beams 30. A number of horizontally movable and rotatable roof bolt drills 37 are installed on the front side of the cross beam 33. A rib bolt drill 38 capable of vertical lifting and rotation is installed on the drill fixing seat 34. Among them, the cable bolt drill 36 can drill and fix cable bolts at various angular positions on the top of the roadway. The roof bolt drill 37 can drill and fix roof bolts at various angular positions on the top of the roadway. The rib bolt drill 38 can drill and fix rib bolts at various angular positions on the side of the roadway.

[0031] The horizontal movement or vertical lifting of each of the above-mentioned drills can be guided by a rack and pinion mechanism or a slide rail and slider mechanism, and a gear with a motor or an oil cylinder, an electric push rod, etc. is used as the driving force. The rotation of the drill can be achieved by a slewing bearing or a driving cylinder connected by a hinge to perform the corresponding angular rotation action.

[0032] To achieve the adaptive support of the gantry multi-drill arm support system 3 in different roadways, as Figure 8 shown, a rear support mechanism is installed at the rear end of the telescopic outer beam 30. The rear support mechanism includes a U-shaped frame 39 fixed to the telescopic outer beam 30. A turning plate 310 is hingedly installed on the U-shaped frame 39. A rear support plate 311 is provided at the end of the turning plate 310. The rear support plate 311 can rotate relative to the U-shaped frame 39 together with the turning plate 310. Clamping plates 312 arranged side by side are provided at the end of the telescopic outer beam 30. A rear support cylinder 313 is installed between the clamping plate 312 and the rear support plate 311. Among them, the cylinder barrel of the rear support cylinder 313 is hinged between the clamping plates 312, and the piston rod of the rear support cylinder 313 is hinged to the rear support plate 311. The extending length of the piston rod of the rear support cylinder 313 can adjust the rotation opening and closing angle of the rear support plate 311 and can press the rear support plate 311 tightly against the inner peripheral wall of the roadway, so as to form a stable support at the rear end position of the gantry multi-drill arm support system 3.

[0033] A front support mechanism is installed on the cross beam 33. When the telescopic inner beam 31 is located inside the telescopic outer beam 30, the cross beam 33 and the front support mechanism are located in the middle position of the whole machine and will not affect the normal advancement of the whole machine in the roadway. When tunneling support is required, the telescopic inner beam 31 extends forward, and the cross beam 33 and the front support mechanism can extend forward above the cutting head 12 for anchoring support, so as to improve the anchoring stability of the whole machine in the roadway during the tunneling operation.

[0034] The front support mechanism includes first front support plates 314 fixed to both ends of the cross beam 33 in the length direction. An anti-collision cushion plate 315 is installed on the top of the first front support plates 314. A number of front support cylinders 316 are installed on the cross beam 33 between the two first front support plates 314. A second front support plate 317 is installed on the piston rod of each front support cylinder 316, and the second front support plate 317 can vertically lift and lower relative to the cross beam 33. The first front support plates 314 at both ends are fixedly arranged. When the multi-boom portal support system 3 makes multi-angle adaptive position adjustment, the ends in the length direction of the cross beam 33 first come into contact with the inner wall of the roadway. Therefore, the corresponding anti-collision cushion plates 315 are provided. The second front support plates 317 at the remaining positions can adjust the height position according to the actual situation to achieve adaptive support for the inner wall of the roadway.

[0035] In order to shield and support the roof bolt drill 37, side bolt drill 38 and other mechanisms on the cross beam 33, and to form necessary contact limits for the forward movement of the cross beam 33, the front ends of the first front support plate 314 and the second front support plate 317 extending out of the cross beam 33 are arc plates bent downward.

[0036] In order to enable the multi-boom portal support system 3 to form a more comprehensive support in the roadway, a side support mechanism is installed at the end of the cross beam 33. The side support mechanism includes a side turning plate 318 hinged to the cross beam 33. A side support plate 319 is provided at the end of the side turning plate 318. A side support cylinder 320 is installed between the side support plate 319 and the cross beam 33 in a hinged manner. The telescopic movement of the piston rod of the side support cylinder 320 can drive the side support plate 319 to rotate and open and close, and press the side support plate 319 against the side of the roadway for support and positioning.

[0037] To achieve support and positioning of the bottom position of the roadway, a vertically arranged lower support cylinder 321 is installed on the outer side of the drill fixing base 34. A positioning cone sleeve 322 is installed on the piston rod of the lower support cylinder 321. When the piston rod of the lower support cylinder 321 extends, it can drive the positioning cone sleeve 322 to move down to the roadway floor and form stable contact support.

[0038] In order to facilitate the anchoring support in the roadway and enable the staff to assist in observing and correcting, so that each anchor drill can perform anchoring support at the set position. Corresponding to the position of the roof bolt drill 37, an auxiliary roof drill platform 323 is installed at the bottom of the cross beam 33. Corresponding to the position of the side bolt drill 38, an auxiliary side drill platform 324 is installed at the bottom of the drill fixing base 34. The above platforms can provide positions for the staff to assist in observing.

[0039] Further, as Figures 9 - 12As shown in the figure, the elastic lifting mechanism 4 includes a top beam 35 provided on the gantry multi-boring arm support system 3. The top beam 35 is fixedly installed on the telescopic outer beam 30 of the gantry multi-boring arm support system 3. At both ends of the top beam 35 corresponding to the length direction, base frames 40 arranged side by side are installed on the frame 1. A fixed sleeve 41 is provided on each base frame 40. An outer guide sleeve 42 is installed in the fixed sleeve 41 through a pin shaft. The outer guide sleeve 42 is made of elastic material and can undergo elastic deformation within a limited range. An inner guide post 43 cooperating with the outer guide sleeve 42 is hingedly installed at the bottom of the top beam 35. Lifting cylinders 44 are installed on the base frames 40 on both sides of the outer guide sleeve 42. The cylinder barrel of the lifting cylinder 44 is hingedly connected to the base frame 40 through a spherical bearing, and the end of the piston rod of the lifting cylinder 44 is hingedly connected to the top beam 35 through a spherical bearing.

[0040] The four groups of lifting cylinders 44 on the elastic lifting mechanism 4 are independently controlled. By respectively controlling the lifting of the four groups of lifting cylinders 44, the inner guide post 43 can move vertically up and down along the outer guide sleeve 42, enabling the vertical lifting, horizontal telescoping, and deflection angle adjustment of the gantry multi-boring arm support system 3 relative to the frame 1, so that the gantry multi-boring arm support system 3 can be inclined in different angular directions to adapt to roadways with different cross-sections and complete adaptive support and anchoring.

[0041] Furthermore, in order to guide the movement of the inner guide post 43 relative to the outer guide sleeve 42, a guiding round shaft 45 is installed in the outer guide sleeve 42, and a guiding groove 46 cooperating with the guiding round shaft 45 is provided on the inner guide post 43. In order to achieve the inclined deformation of the outer guide sleeve 42 at different angular positions, the outer guide sleeve 42 is made of spring steel plate.

[0042] Furthermore, as Figure 13 shown, the forward exploration drilling rig system 5 includes a drilling rig 50. A first slewing bearing 51 is installed on the frame 1. A connecting plate 52 is installed on the inner ring of the first slewing bearing 51. A second slewing bearing 53 is installed on the upper side of the end of the connecting plate 52 away from the first slewing bearing 51. The drilling rig 50 is installed on the inner ring of the second slewing bearing 53. The first slewing bearing 51 and the second slewing bearing 53 are respectively located at the upper and lower positions at both ends of the length direction of the connecting plate 52. Through the rotation drive of the first slewing bearing 51 and the second slewing bearing 53, the drilling rig 50 can be driven to perform drilling exploration at different angular positions on the roadway driving face, and at the same time, it can also perform drilling exploration at various inclined angles at other positions such as the side of the roadway.

[0043] Furthermore, as Figure 14 and Figure 15As shown, the scraper plate mechanism 2 includes a scraper plate main body 20. At the end of the scraper plate main body 20, there are a connecting ear seat 21 and an oil cylinder ear seat 22. The connecting ear seat 21 is used for hinged installation on the frame 1, and between the oil cylinder ear seat 22 and the frame 1, a swing oil cylinder is installed, and the rotation, lifting or lowering of the scraper plate mechanism 2 is realized through the telescopic drive of the swing oil cylinder.

[0044] On the scraper plate main body 20, there are also two groups of star wheel rake claws 23 arranged symmetrically. On the scraper plate main body 20 between the two groups of star wheel rake claws 23, there is a guide groove matching with the material conveyor belt 13. Wear-resistant plates 24 are arranged in the guide groove. The rotation directions of the two groups of star wheel rake claws 23 are opposite and both rotate towards the inner side of the scraper plate main body 20, and the materials such as earth and stone on the scraper plate main body 20 can be transferred to the material conveyor belt 13 between the star wheel rake claws 23. At the front end of the scraper plate main body 20, there are several scraper teeth 25. On both sides of the scraper plate main body 20, expandable scraper plates 27 that can be telescoped are installed through side extension cylinders 26. By adjusting the extended position of the expandable scraper plates 27, the overall scraper plate mechanism 2 can be adapted to the width distance in the roadway. During the tunneling process, the excavated materials such as earth and stone can all directly fall onto the scraper plate main body 20, realizing full-section material collection operation, facilitating collection and transportation, and avoiding falling to the bottom of the roadway and affecting the subsequent passage of the overall equipment.

[0045] Furthermore, in order to preliminarily crush the earth and stone with a relatively large diameter on the material conveyor belt 13 and avoid the phenomenon that the earth and stone with a large diameter get stuck on the material conveyor belt 13, as Figure 16 and Figure 17 shown, the material conveyor belt 13 includes a drive chain 130. On the corresponding drive chain 130, there are scraper plates 131 installed. On the upper surface of each scraper plate 131, there are planing teeth 132. There is an inclined surface 133 on the planing teeth 132, and the position of the inclined surface 133 on the planing teeth 132 is consistent with the direction of material conveyance.

[0046] On the frame 1 above the material conveyor belt 13, a baffle 134 is installed. When the earth and stone driven by the scraper plate 131 move to the position of the baffle 134, if it can directly pass through the space between the baffle 134 and the scraper plate 131, it indicates that the diameter of the earth and stone meets the requirements and will not get stuck during transportation. If the diameter of the earth and stone exceeds the limit range, it will be clamped between the baffle 134 and the planing teeth 132 of the scraper plate 131. And with the continuous rotation of the drive chain 130, the earth and stone are squeezed by the baffle 134 and the scraper plate 131. The planing teeth 132 and the baffle 134 can extrude and plane the large-diameter material to break it. After the diameter of the extruded and broken earth and stone meets the requirements, it can pass smoothly. If it still does not meet the passing requirements, it can continue to be extruded and planed until it can pass, thereby realizing the preliminary crushing treatment of the earth and stone with a relatively large diameter on the material conveyor belt 13 and avoiding the phenomenon of getting stuck during subsequent transportation.

[0047] In the utility model, the gantry multi-boom support system 3 has the functions of lifting, telescoping, and angle adjustment. The airborne drill rigs arranged on the gantry mechanism are moved to the working position through functions such as telescoping and lifting. Moreover, each drill rig has a lifting, horizontal sliding, and slewing mechanism on the gantry mechanism, and can perform anchor support operations after moving to the corresponding position. The forward exploration drill rig system 5 is located on the front side of the whole machine, and the drilling azimuth can be adjusted through a multi-stage slewing mechanism, which can meet the long-distance drilling requirements in the front and both sides.

[0048] The upper and lower ends of the elastic lifting mechanism 4 are respectively hinged to the top beam 35 and the base frame 40. Through the action of the lifting cylinder 44, the top beam 35 and the telescopic outer beam 30 perform vertical lifting, lateral angle adjustment, and longitudinal angle adjustment. The all-round support of the front support mechanism, side support mechanism, rear support mechanism, and lower support mechanism improves the working stability of the gantry mechanism. Moreover, through the gantry mechanism, the working positions and working states of multiple drill rigs are adjusted. It has high structural strength and good working stability. Multiple drill rigs can realize rapid support operations, which can greatly improve the footage speed. Moreover, the drill rigs only need to perform lateral, vertical, and slewing motions, and the drilling positioning speed is fast and the working efficiency is high.

[0049] Since the gantry multi-boom support system 3 adopts a gantry longitudinal movement structure, has two long-distance telescopic beams, and the equipment width is relatively large, it is necessary to adopt a lifting and angle adjustment mechanism with elastic deformation, that is, the elastic lifting mechanism 4. Spring steel plates are used as the outer guide sleeve 42, and multiple groups of oil cylinders are used to control the lifting and angle adjustment of the inner guide column 43, which meets the structural design requirements of the gantry roadheader-anchor machine and prevents structural damage caused by non-synchronization.

[0050] Among them, the outer guide sleeve 42 is made of spring plates. By adjusting the stroke of the lifting cylinders 44 on the left and right positions, the top beam 35 can be tilted left and right. At this time, the outer guide sleeve 42 is deformed by external forces and tilts following the top beam 35. The lifting cylinders 44 are arranged left and right, with two on each side. By controlling the different telescopic strokes of the four oil cylinders, the top frame can be made horizontal and tilted in the front and rear directions. The four oil cylinders can be independently controlled, and different telescopic strokes can adjust the horizontal and front and rear direction angle changes of the top beam 35, the outer guide sleeve 42, and the inner guide column 43.

[0051] Through the cooperative operation of the four lifting cylinders 44, the adjustment of the top beam 35 in the front and rear, left and right directions and the vertical lifting operation are realized. Through the use of spring steel plates, beneficial deformation can occur under external forces to prevent mechanical interference. The frame structure improves the strength of the lifting mechanism and ensures the normal operation of the equipment.

[0052] The extended cutting plate 27 in the cutting plate mechanism 2 can ensure that the side of the cutting plate is closely attached to the side wall of the roadway, ensuring that the roadheader is always located in the middle of the roadway. Combined with the function of the telescopic large-stroke cutting part for hard rock, it realizes the full-section automatic positioning cutting operation, improving the tunneling speed. The material collection is completed by the rotation of the star wheel scraper 23, and the hard alloy cutting teeth 25 arranged at the front have the functions of assisting in cleaning and leveling the roadway floor.

[0053] The above-mentioned cutting plate mechanism 2 realizes the centering of the roadheader during construction. The specially designed wide section realizes the one-time material collection operation, greatly improving the equipment adaptability. It can adapt to the material collection operation of roadways with different widths, forming in one go according to the pre-set program. The roadway forming speed is fast and the accuracy is high. The cutting and material collection actions do not rely on manual operation, getting rid of the skill dependence on the roadheader driver, avoiding the time for the equipment to move left and right during tunneling. When cutting a roadway with a large cross-section, high rock hardness and poor conditions, it realizes continuous operation in one bolt support operation cycle, avoiding secondary repair, greatly reducing the operation time and improving the production efficiency.

[0054] The technical solution of the present utility model is not limited within the scope of the embodiments described in the present utility model. The technical content not described in detail in the present utility model is well-known technology.
