Description

[0002] Currently, there are two types of coal roadway comprehensive excavating machines: EBZ series longitudinal axis type roadheader and integrated excavating and anchoring machine. The EBZ series longitudinal axis type roadheader has strong applicability, mature technology, and is widely used, with a monthly average footage of 180-280 meters. However, the roadheader does not integrate a rock bolt drilling machine, and the time for supporting operation accounts for more than 80% of the total operation time, resulting in low construction efficiency. The integrated excavating and anchoring machine integrates a rock bolt drilling machine, with a monthly average footage of 400-480 meters. However, due to the limited supporting capacity, the machine has poor adaptability and is required to have strict geological conditions for excavating a roadway. SUMMARY

DETAILED DESCRIPTION

[0068] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0069] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can also be implemented in other manners different from those described herein; obviously, the embodiments in the description are only a part of the embodiments of the present application, not all the embodiments.

[0070] In one embodiment, as Figures 1 to 10As shown, an integrated anchor and support device is provided, which comprises a frame 1, a drum-type cutting mechanism 2, a shovel plate mechanism 3, a main anchor drilling device 4, a side anchor drilling device 5, an intermediate top anchor drilling device 6, a bottom side anchor drilling device 7 and a support device 8. The bottom of the frame 1 is provided with a traveling mechanism 11, and the frame 1 is internally provided with a transport mechanism 12 which penetrates the frame 1 in the front-rear direction. The drum-type cutting mechanism 2 comprises a drum-type cutting head 21, a cutting swing arm 22 and a cutting driving member. The axis of the drum-type cutting head 21 is arranged in the left-right direction. One end of the cutting swing arm 22 is connected with the drum-type cutting head 21, and the other end is hinged with the frame 1. The cutting driving member is fixed on the frame 1 and is adapted to drive the cutting swing arm 22 to swing in the vertical plane in the front-rear direction. The shovel plate mechanism 3 is located at the front end of the frame 1 and below the drum-type cutting head 21, and is in abutment with the transport mechanism 12. The main anchor drilling device 4 comprises two groups of main anchor drilling mechanisms 41 which are symmetrically distributed in the left-right direction. An avoiding area is left between the two groups of main anchor drilling mechanisms 41 for avoiding the cutting swing arm 22. Each group of main anchor drilling mechanisms 41 comprises a main top anchor drilling machine 411 and a main top side anchor drilling machine 412. The main top anchor drilling machine 411 is located outside the main top side anchor drilling machine 412 in the left-right direction. All the main anchor drilling mechanisms 41 are driven to move in the front-rear direction and eccentrically rotate about a vertical shaft. The main top side anchor drilling machine 412 is driven to extend and retract along its axis and rotate about a horizontal shaft. The side anchor drilling device 5 is located behind the main anchor drilling device 4. The side anchor drilling device 5 comprises two groups of side anchor drilling mechanisms 51 which are symmetrically distributed in the left-right direction. The side anchor drilling mechanism 51 comprises a side anchor drilling machine 511. All the side anchor drilling machines 511 are driven to lift, translate in the front-rear direction, translate in the left-right direction and rotate about an axis arranged in the front-rear direction. The intermediate top anchor drilling device 6 is located behind the side anchor drilling device 5 and corresponds to the avoiding area between the two groups of main anchor drilling mechanisms 41 in the front-rear direction. The intermediate top anchor drilling device 6 comprises an intermediate top anchor drilling machine 61. The intermediate top anchor drilling machine 61 is driven to translate in the front-rear direction and translate in the left-right direction. The bottom side anchor drilling device 7 is located at the rear end of the frame 1. The bottom side anchor drilling device 7 comprises two groups of bottom side anchor drilling mechanisms 71 which are symmetrically distributed in the left-right direction. The bottom side anchor drilling mechanism 71 comprises a bottom side anchor drilling machine 711. The bottom side anchor drilling machine 711 is driven to rotate about an axis arranged in the front-rear direction. The support device 8 comprises a horizontally arranged support net plate 81. The support net plate 81 is located above the main anchor drilling device 4. The support net plate 81 is driven to lift and move in the front-rear direction.

[0071] Specifically, the traveling mechanism 11 can be selected from the structures commonly used in the art, such as traveling wheels, traveling caterpillar belts, etc. Preferably, the traveling caterpillar belt is adopted, which can better adapt to the complex road surface environment in the mine.

[0072] It is easy to understand that the main function of the transport mechanism 12 is to transport the scattered coal after cutting to the outside of the device. Specifically, the transport mechanism 12 can adopt a conventional conveying device such as a conveying belt.

[0073] It is easy to understand that how the cutting drive drives the cutting swing arm 22 to swing is easy to be designed by those skilled in the art, for example, the cutting drive is a linear drive such as a pneumatic cylinder, an oil cylinder, etc., and is hinged at one end to the rack 1 and at the other end to the middle of the cutting swing arm 22, and the swing of the cutting swing arm 22 is driven by the extension and retraction of the linear drive; or a rotary drive is directly installed at the hinge point of the cutting swing arm 22 and the rack 1, and the swing of the cutting swing arm 22 is driven by the rotation of the rotary drive.

[0074] It should be noted that the aforementioned terms "front", "back", "left" and "right" are used for more clearly describing the relative position relationship of the components, "front" means the direction of the whole device moving forward, "back" means the opposite direction of "front", and "left" and "right" are located on the two sides of the forward direction.

[0075] It should be noted that the shovel plate mechanism 3 is a relatively mature structure in the coal roadway fully mechanized excavation equipment, which will not be described in detail here.

[0076] Specifically, the movement and rotation of the anchor drills such as the main anchor drill, the side anchor drill 511, the middle roof anchor drill 61 and the bottom side anchor drill 711 are driven by the existing structure. For example, the movement is achieved by a telescopic pneumatic cylinder, a linear motor, a motor synchronous belt assembly, etc., and the rotation is achieved by a rotary pneumatic cylinder, a motor, etc.

[0077] It should be noted that the main function of the supporting device 8 is to support the corresponding part between the main anchor drills to avoid the falling and collapse of the anchor drill part. After the main anchor drill is completed, the anchor drill part has been supported, and the subsequent side anchor drill, middle roof anchor drill and bottom side anchor drill no longer need the support of the supporting device 8.

[0078] Specifically, the supporting device 8 is a mature structure in the art, and the main body of the structure is generally a mesh plate structure, and the mesh holes of the mesh plate are reserved for the positions of the anchor drills.

[0079] The working process of the above-mentioned integrated excavation, anchoring and supporting device is as follows:

[0080] Firstly, the cutting driving member drives the cutting swing arm 22 to swing, and drives the drum-type cutting head 21 to cut coal from top to bottom, and the shovel plate mechanism 3 pushes the fallen coal to avoid entering the inside of the equipment, and outputs the coal through the external conveying mechanism; after the first cutting of the unit, the supporting device 8 acts to complete the support of the position to be anchored; then, the two groups of main anchor drilling mechanisms 41 of the main anchor drilling device 4 act to anchor the roof with anchor rods, and after the completion of the main roof anchor drilling mechanism 412 of the two main anchor drilling mechanisms 41, the side wall anchor drilling mechanism 412 rotates to the two sides to gradually complete the anchor rod support of the side wall; after the second cutting of the unit, the roof anchor drilling device 5 reaches the section where the main anchor drilling has been completed, and the roof anchor drilling device 5 adjusts the position by moving and rotating to support the remaining part of the main anchor rod; after the third cutting of the unit, the intermediate roof anchor drilling device 6 reaches the section, and the intermediate roof anchor drilling device 6 acts to support the roof with anchor rods to make up for the omission of the main anchor drilling device 4; after the fourth cutting of the unit, the bottom roof anchor drilling device 7 reaches the section, and the bottom roof anchor drilling device 7 acts to support the bottom edge with anchor rods; in this way, the section of the roadway has been fully supported, and the support is completed.

[0081] The tunneling, anchoring and supporting integrated device provided by the embodiment is provided with a rack 1, a drum-type cutting mechanism 2 and a shovel plate mechanism 3, which can meet the basic requirements of excavation and mining; the device is also provided with a main anchor drilling device 4, a roof anchor drilling device 5, an intermediate roof anchor drilling device 6 and a bottom roof anchor device, and the main anchor drilling device 4 is correspondingly provided with a supporting device 8, which integrates tunneling, anchoring and supporting in one, shortens the support time, improves the construction efficiency, and through the cooperation of the four anchoring devices, the full section can be anchored, which greatly improves the support capacity and can be applied to most coal roadway comprehensive tunneling, and has stronger adaptability.

[0082] In some embodiments, with reference to Figure 2 The drum-type cutting head 21 includes a cutting head body 211 and two groups of extended cutting heads 212; the cutting head body 211 is connected with the cutting swing arm 22; the two groups of extended cutting heads 212 are coaxially sleeved on the inner sides of the two ends of the cutting head body 211, and the extended cutting heads 212 are driven to slide along the axial direction of the cutting head body 211 to extend out of the cutting head body 211.

[0083] Specifically, the extended cutting heads 212 can be driven to slide along the axial direction of the cutting head body 211 by telescopic pneumatic cylinders, telescopic oil cylinders or motor synchronous belt groups.

[0084] In specific implementation, in order to smoothly enter the excavated roadway, the width of the drum-type cutting head 21 in the left-right direction should be greater than the width of the main body of the vehicle body, and the extended cutting heads 212 can increase the width of the drum-type cutting head 21 by sliding to extend out of the cutting head body 211, thereby meeting this requirement; and the extended cutting heads 212 can also increase the one-time cutting area and improve the cutting efficiency.

[0085] As a further improved embodiment, referring to Figure 3 , the shovel plate mechanism 3 comprises a shovel plate base 31 and two groups of shovel plate assemblies 32; the shovel plate base 31 is connected to the front end of the frame 1 through a shovel plate connecting arm; the two groups of shovel plate assemblies 32 are respectively located at the left and right ends of the shovel plate base 31, and a discharging area 33 is left between the two groups of shovel plate assemblies 32, the discharging area 33 is connected to the conveying mechanism 12, the shovel plate assembly 32 comprises a lower fixed shovel plate 321, a lower movable shovel plate 322 and an upper movable shovel plate 323, the lower fixed shovel plate 321 is fixed on the shovel plate base 31, the lower movable shovel plate 322 is installed on the lower fixed shovel plate 321 and is driven to slide left and right relative to the lower fixed shovel plate 321 to extend outward from the lower fixed shovel plate 321, and the lower end of the upper movable shovel plate 323 is hinged to the top end of the lower movable shovel plate 322, and the middle part of the upper movable shovel plate 323 is hinged to the shovel plate connecting arm through a linear driving element to realize overturning.

[0086] It is easy to understand that the main function of the discharging area 33 connected to the conveying mechanism 12 is to collect and concentrate the scattered coal after cutting to the rear of the equipment.

[0087] In specific implementation, the lower movable shovel plate 322 extends outward from the lower fixed shovel plate 321 to realize the expansion of the shovel plate assembly 32 in the left and right directions, so as to adapt to the width change of the drum-type cutting head 21; the upper movable shovel plate 323 can be overturned to increase the height of the shovel plate assembly 32, thereby increasing the coal blocking capacity.

[0088] In some embodiments, referring to Figure 4 and Figure 5 , the main anchor drilling mechanism 41 further comprises a sliding platform 413, a first support shaft 414 and a first horizontal sliding pair; the sliding direction of the sliding platform 413 is the front and back direction; the first support shaft 414 is rotatably installed on the sliding platform 413 and is vertically arranged, and the first support shaft 414 is driven to rotate; the fixed part of the first horizontal sliding pair is fixed on the first support shaft 414; the main top anchor drilling machine 411 is fixed on the sliding part of the first horizontal sliding pair, and the axis of the main top anchor drilling machine 411 is vertically arranged.

[0089] Specifically, the first horizontal sliding pair can be a telescopic oil cylinder, a telescopic air cylinder, a motor synchronous belt, etc.; the first support shaft 414 can be driven to rotate by a rotary cylinder, a motor, etc.

[0090] In specific implementation, the main top anchor drilling machine 411 moves forward and backward through the sliding platform 413 and the horizontal sliding pair, and rotates eccentrically around the vertical shaft through the rotation of the first support shaft 414 in cooperation with the horizontal sliding pair. The sliding platform 413 can realize the sliding of the main top anchor drilling machine 411 in the front and back direction, the first horizontal sliding pair can increase the sliding stroke of the main top anchor drilling machine 411 in the front and back direction, and the main top anchor drilling machine 411 can be more flexible in adjusting the hole.

[0091] Further, referring toFigure 5 The main anchor drilling mechanism 41 further comprises a second support shaft 415, a second horizontal sliding pair, a rotating pair 416 and an extension pair 417. The second support shaft 415 is rotatably installed on the sliding platform 413 and vertically arranged, and is driven to rotate. The fixed part of the second horizontal sliding pair is fixed to the second support shaft 415. The fixed part of the rotating pair 416 is fixed to the sliding part of the second horizontal sliding pair, and the rotating shaft of the rotating pair 416 is horizontally arranged. The fixed part of the extension pair 417 is fixed to the rotating part of the rotating pair 416, and the extension direction of the extension pair 417 is perpendicular to the rotating shaft of the rotating pair 416. The main top anchor drilling machine 412 is fixed to the movable part of the extension pair 417, and the axis of the main top anchor drilling machine 412 is parallel to the extension direction of the extension pair 417.

[0092] Specifically, the second horizontal sliding pair can be an extension oil cylinder, an extension air cylinder, a motor synchronous belt, etc. The second support shaft 415 can be driven to rotate by a rotating air cylinder, a motor, etc. The rotating pair 416 can be a rotating motor, a rotating air cylinder, etc. The extension pair 417 can be an extension oil cylinder, an extension air cylinder or an electric push rod.

[0093] It is easy to understand that the main top anchor drilling machine 412 has two more degrees of freedom than the main top anchor drilling machine 411 because the main top anchor drilling machine 412 not only completes the top anchor support of the foundation, but also completes the side wall anchor through rotation.

[0094] In specific implementation, the main top anchor drilling machine 412 moves forward and backward through the sliding platform 413 and the second horizontal sliding pair, rotates around a horizontal shaft through the rotating pair 416, extends along its axis through the extension pair 417, and eccentrically rotates around a vertical shaft through the rotation of the second support shaft 415 in cooperation with the second horizontal sliding pair.

[0095] As another improved embodiment of the above embodiment, referring to Figure 9 and Figure 11 The support device 8 further comprises an expansion support mechanism 82, which is provided with two groups and is located on the left and right sides of the main anchor drilling device 4. The expansion support mechanism 82 comprises a left and right extension driving pair 821, an expansion main frame 822, an upper expansion frame 823 and a front expansion frame 824. The fixed part of the left and right extension driving pair 821 is fixed to the sliding platform 413. The expansion main frame 822 is vertically arranged, and its lower end is fixed to the movable part of the left and right extension driving pair 821. The upper expansion frame 823 is installed in the expansion main frame 822 and can be driven to slide upward to extend outward from the expansion main frame 822. The front expansion frame 824 is installed in the expansion main frame 822 and can be driven to slide forward to extend outward from the expansion main frame 822.

[0096] Specifically, the left and right extension driving pair 821 can be a linear motor, an extension air cylinder, a hydraulic oil cylinder, etc.

[0097] In practice, the expansion support structure can support the sidewall in advance, avoiding the sidewall from falling during anchor drilling. The upper expansion frame 823 and the front expansion frame 824 can respectively increase the height and length of the expansion support structure, thereby increasing the support area and improving the support capacity.

[0098] In some embodiments, referring to Figure 6 , the helper anchor drilling mechanism 51 further comprises a left-right sliding pair 512, an up-down sliding pair 513, a rotating pair 514, and a front-rear sliding pair 515. The fixed part of the left-right sliding pair 512 is fixed to the frame 1. The fixed part of the up-down sliding pair 513 is fixed to the sliding part of the left-right sliding pair 512.
