AI Technical Summary
[0004]现有的帮锚系统实现前后位置调整有两种形式：第一种是预留安装孔位式，将帮锚系统拆下后调整安装孔位后再安装，这种方式无法实时调整帮锚杆钻机前后位置，与顶锚杆钻机排距固定，无法根据巷道支护情况进行实时调整，适应性差；第二种是前后滑移式，帮锚系统前后滑动安装在工作平台上表面，虽然可以及时调整帮锚杆钻机与顶锚杆钻机排距，但是帮锚系统的帮锚杆钻机与其提升装置一般为前后布置，导致帮锚系统在巷道前后方向尺寸较大，减小了工作平台的施工空间，挤压了施工人员的工作空间，降低了施工便捷性和安全性
[0008]有益效果：帮锚杆钻机、帮锚连接架、倍增程提升架和前后滑移架左右间隔布置并组装在一体构成帮锚系统，如此，该帮锚系统在巷道前后方向尺寸仅为帮锚杆钻机的前后方向尺寸，相比传统的帮锚系统在巷道前后方向尺寸大大减小，增大了工作平台的施工空间，较小挤压施工人员的工作空间，增加了施工便捷性和安全性，同时，前后滑移架在工作平台一侧边缘的立板箱体上前后滑动，帮锚前后滑移油缸的两端分别连接在前后滑移架和立板箱体上，既保证了帮锚系统前后滑动，又进一步节省了工作平台的施工空间，不会影响施工人员施工操作。

Description
Technical Field
[0001] This utility model relates to the field of tunnel excavation equipment technology, specifically to a tunneling and anchoring integrated machine with a side anchoring system. Background Technology
[0002] In coal mine roadway excavation, geological conditions, roadway cross-sections, anchor bolt spacing, row spacing, and installation angles vary. Therefore, different anchor bolt arrangement parameters must be selected according to the specific conditions of each roadway when providing support. Furthermore, to ensure the effectiveness of anchor bolt support, the installation angle of the anchor bolts should not be too large; ideally, they should be perpendicular to the roof or sidewalls.
[0003] The roadheader-anchor (BAR) is a mainstream type of equipment for coal mine roadway excavation and a key piece of equipment in rapid excavation systems, integrating excavation and anchoring. The BAR's anchoring system includes a top anchor system and a side anchor system. The top anchor system provides bolt support to the roadway roof, allowing for lateral sliding, lateral swinging, and forward / backward swinging. The side anchor system provides bolt support to the roadway sides, allowing for forward / backward sliding, upward / downward sliding, and upward / downward swinging.
[0004] There are two existing methods for adjusting the front and rear positions of the anchoring system: The first is the pre-drilled installation hole type, where the anchoring system is removed, the installation hole position is adjusted, and then it is reinstalled. This method cannot adjust the front and rear positions of the anchoring drill in real time, and the spacing between it and the top anchoring drill is fixed. It cannot be adjusted in real time according to the roadway support conditions, resulting in poor adaptability. The second method is the front and rear sliding type, where the anchoring system is slidably installed on the surface of the working platform. Although the spacing between the anchoring drill and the top anchoring drill can be adjusted in time, the anchoring drill and its lifting device are generally arranged front and rear, resulting in a large front and rear dimension of the anchoring system in the roadway. This reduces the construction space of the working platform, squeezes the workspace of the construction personnel, and reduces the convenience and safety of construction.
[0005] Meanwhile, the sliding cylinders that drive the anchoring system are located on the upper surface of the work platform, which will further encroach on the construction space of the work platform and affect the construction operations of the construction personnel. Summary of the Invention
[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing an integrated tunneling and anchoring machine support system. This utility model increases the construction space of the working platform, enhances construction convenience and safety, and significantly expands the support range of the support anchor drilling rig.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a tunneling and anchoring machine support anchoring system, wherein a set is respectively set on the left and right working platforms of the tunneling and anchoring machine, the two sets of tunneling and anchoring machine support anchoring systems have the same structure and are symmetrical left and right, the left tunneling and anchoring machine support anchoring system includes a support anchoring drill, a support anchoring connecting frame, a range multiplier lifting frame and a front and rear sliding frame arranged at intervals on the left and right. The right end of the anchor bolt drilling rig is hinged to the anchor bolt connecting frame, and the anchor bolt drilling rig and the anchor bolt connecting frame are connected by an anchor bolt swing cylinder for driving the anchor bolt drilling rig to swing up and down. The anchor connection frame is installed on the multiplier lifting frame and the multiplier lifts and lowers under the drive of the multiplier lifting frame; The range multiplier lifting frame is slidably mounted on the front and rear sliding frames, and the range multiplier lifting frame and the front and rear sliding frames are connected by an anchor sliding cylinder. A vertical plate box is set on the right edge of the left working platform. The front and rear sliding frames are slidably installed on the left side of the vertical plate box. The front and rear sliding frames are connected to the vertical plate box by a front and rear sliding cylinder.
[0008] Beneficial effects: The anchor bolt drilling rig, anchor bolt connecting frame, multiplier lifting frame, and front and rear sliding frames are arranged and assembled into an integrated anchor bolt system with left and right intervals. In this way, the front and rear dimensions of the anchor bolt system in the roadway are only the front and rear dimensions of the anchor bolt drilling rig, which is much smaller than the traditional anchor bolt system. This increases the construction space of the working platform, reduces the compression of the working space of the construction personnel, and increases the convenience and safety of construction. At the same time, the front and rear sliding frames slide back and forth on the vertical plate box on one side edge of the working platform. The two ends of the front and rear sliding cylinders of the anchor bolt are connected to the front and rear sliding frames and the vertical plate box respectively, which not only ensures the front and rear sliding of the anchor bolt system, but also further saves the construction space of the working platform and does not affect the construction personnel's operation.
[0009] Furthermore, the lifting frame can be used to increase the range of the rock bolt drilling rig. At the same time, the lifting frame can also be raised and lowered on the front and rear sliding frames via the sliding cylinders of the rock bolt. In this way, the rock bolt drilling rig can slide up and down over a wide range, thereby greatly increasing the support range of the rock bolt drilling rig.
[0010] Based on the above, the range multiplier lifting frame includes a frame body, guide columns, range multiplier sliders, and a stroke multiplier mechanism. The frame body is a vertical, long box-shaped structure with an open left side. The guide columns are vertically installed inside the frame body, with their upper and lower ends fixedly connected to the top and bottom plates of the frame body, respectively. The range multiplier sliders are slidably connected to the guide columns. The stroke multiplier mechanism is installed inside the frame body and drives the range multiplier sliders to rise and fall on the guide columns. The anchoring frame is fixedly installed on the left side of the range multiplier sliders. The right side plate of the frame body has vertically fixed upper and lower sliding guide rails for sliding connection with the front and rear sliding frames.
[0011] Beneficial effects: The stroke multiplier mechanism can multiply the lifting and lowering stroke of the anchor bolt drilling rig on the frame, thereby increasing the range of upward and downward sliding of the anchor bolt drilling rig.
[0012] Based on the above, the front and rear sliding frame includes front and rear sliding plates, which are arranged parallel to the upright plate box. Front and rear sliding guide rails are fixedly installed on the left side of the upright plate box along the front and rear direction. The front and rear sliding plates are slidably connected to the front and rear sliding guide rails. The front and rear ends of the anchor front and rear sliding cylinders are respectively hinged to the front and rear sliding plates and the upright plate box. The left side of the front and rear sliding plates is fixedly installed with upper and lower sliding plates that are slidably connected to the upper and lower sliding guide rails. The upper and lower ends of the anchor upper and lower sliding cylinders are respectively hinged to the upper and lower sliding plates and the frame.
[0013] Beneficial effects: The front and rear sliding cylinders of the anchor bolting machine drive the front and rear sliding plates to slide back and forth on the front and rear sliding guide rails of the vertical plate box, thus realizing the front and rear sliding of the anchor bolting machine. Moreover, the front and rear sliding cylinders of the anchor bolting machine do not occupy the construction space of the work platform, thus saving the construction space of the work platform and not affecting the construction operation of the construction personnel. At the same time, through the upward and downward sliding connection between the upper and lower sliding plates and the upper and lower sliding guide rails, the frame can be raised and lowered on the upper and lower sliding plates under the drive of the upper and lower sliding cylinders of the anchor bolting machine, thereby realizing the raising and lowering of the anchor bolting machine.
[0014] In summary, the side anchoring system of this utility model optimizes and reduces the dimensions in the front and rear directions of the roadway, increases the construction space of the working platform, reduces the compression of the working space of construction personnel, and increases the convenience and safety of construction. At the same time, it enables the side anchor drilling rig to slide up and down over a wide range, thereby significantly increasing the support range of the side anchor drilling rig.

Detailed Implementation
[0021] The technical solution of this utility model will be further described in detail below through specific embodiments.
[0022] like Figures 1-5 As shown, a roadheader-anchor integrated machine support anchoring system is provided on the left and right working platforms 17 of the roadheader-anchor integrated machine. The two support anchoring systems of the roadheader-anchor integrated machine have the same structure and are symmetrical. The support anchoring system of the roadheader-anchor integrated machine on the left includes a support anchor drill 1, a support anchor connecting frame 2, a range multiplier lifting frame 3 and a front and rear sliding frame 4 arranged at intervals on the left and right. The right end of the anchor bolt drilling machine 1 is hinged to the anchor bolt connecting frame 2. An anchor bolt swing cylinder 5 is connected between the anchor bolt drilling machine 1 and the anchor bolt connecting frame 2 to drive the anchor bolt drilling machine 1 to swing up and down. The anchoring frame 2 is installed on the multiplier lifting frame 3 and its range is increased and decreased under the drive of the multiplier lifting frame 3; The range-multiplying lifting frame 3 is slidably mounted on the front and rear sliding frames 4. The range-multiplying lifting frame 3 and the front and rear sliding frames 4 are connected by an anchor sliding cylinder 6. A vertical plate box 7 is provided on the right edge of the working platform 17 on the left side. The front and rear sliding frame 4 is slidably installed on the left side of the vertical plate box 7. A front and rear sliding cylinder 8 is connected between the front and rear sliding frame 4 and the vertical plate box 7.
[0023] The range multiplier lifting frame 3 includes a frame body 9, guide columns 10, range multiplier sliders 11, and a stroke multiplier mechanism 12. The frame body 9 is a vertical, long box-shaped structure with an open left side. The guide columns 10 are vertically installed inside the frame body 9, and the upper and lower ends of the guide columns 10 are fixedly connected to the top and bottom plates of the frame body 9, respectively. The range multiplier sliders 11 are slidably connected to the guide columns 10. The stroke multiplier mechanism 12 is installed inside the frame body 9 and drives the range multiplier sliders 11 to rise and fall on the guide columns 10. The anchoring frame 2 is fixedly installed on the left side of the range multiplier sliders 11. The right side plate of the frame body 9 has vertically fixed upper and lower sliding guide rails 13 for sliding connection with the front and rear sliding frames 4.
[0024] The front and rear sliding frame 4 includes a front and rear sliding plate 14, which is arranged parallel to the upright plate box 7. A front and rear sliding guide rail 15 is fixedly installed on the left side of the upright plate box 7 along the front and rear direction. The front and rear sliding plate 14 is slidably connected to the front and rear sliding guide rail 15. The front and rear ends of the anchor front and rear sliding cylinder 8 are respectively hinged to the front and rear sliding plate 14 and the upright plate box 7. An upper and lower sliding plate 16, which is slidably connected to the upper and lower sliding guide rail 13, is fixedly installed on the left side of the front and rear sliding plate 14. The upper and lower ends of the anchor upper and lower sliding cylinder 6 are respectively hinged to the upper and lower sliding plate 16 and the frame 9.
[0025] The stroke multiplier mechanism 12 is a conventional technology that can multiply the stroke of the rock bolt drilling rig 1 as it slides up and down.
[0026] In use, this invention utilizes a front and rear sliding cylinder 8 to drive a front and rear sliding plate 14 to slide back and forth on the front and rear sliding guide rails 15 of the vertical plate box 7. This, in turn, causes the frame 9 and the anchor bolt drill 1 to slide back and forth, allowing for timely adjustment of the spacing between the anchor bolt drill 1 and the top anchor bolt drill 18. Since the front and rear sliding cylinder 8 no longer occupies the construction space of the work platform 17, it saves construction space and does not affect the operation of construction personnel. The anchor bolt drill 1, anchor bolt connecting frame 2, multiplier lifting frame 3, and front and rear sliding frame 4 are arranged at intervals on the left and right sides. Thus, the front and rear dimensions of this anchor bolt system in the roadway are only the same as the front and rear dimensions of the anchor bolt drill 1, significantly reducing the front and rear dimensions compared to traditional anchor bolt systems. This increases the construction space of the work platform 17, reduces the pressure on the work space of construction personnel, and increases construction convenience and safety.
[0027] When the anchor bolt drilling rig 1 slides up and down, on the one hand, the stroke multiplication mechanism 12 of the stroke multiplication lifting frame 3 drives the stroke multiplication slider 11 to rise and fall on the guide column 10, and then the stroke multiplication slider 11 drives the anchor bolt connecting frame 2 and the anchor bolt drilling rig 1 to achieve stroke multiplication lifting. On the other hand, the frame 9 of the stroke multiplication lifting frame 3 can also rise and fall on the upper and lower sliding plates 16 of the front and rear sliding frames 4 through the anchor bolt sliding cylinder 6, and then the frame 9 can also drive the anchor bolt drilling rig 1 to rise and fall. In this way, the anchor bolt drilling rig 1 can be moved up and down over a large range, thereby greatly increasing the support range of the anchor bolt drilling rig 1.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
