Description

Technical Field

[0001] The present invention relates to the technical field of full-face hard rock tunnel boring machines, and more particularly to a TBM hydraulic anchor rod rotating and feeding device. Background Art

[0002] TBM generally refers to a full-section hard rock tunnel boring machine, which has the advantages of fast excavation speed, environmental protection, and high comprehensive benefits. It can realize long-term rapid construction in complex geographical terrain that is difficult to achieve with traditional drilling and blasting methods. TBM mainly includes a cutterhead, a main drive system, a shield, a propulsion system, a support system, a main machine belt conveyor, an auxiliary support system, etc. Among them, the anchor drill rig is one of the key equipment for anchor support construction, which is directly related to whether the TBM can be excavated safely and smoothly and whether the project quality can meet the design requirements. In the existing technology, the anchor rod controls the motor assembly on the large gear ring through a wireless controller to rotate. The angle of rotation from the side of the large gear ring to the front is overly dependent on the wireless controller. Once the motor assembly is displaced, there will be a certain angle deviation from the tunnel normal when it rotates to the advance support grouting position. When it rotates to the support position, it cannot be parallel to the face and cannot achieve precise support. Summary of the Invention

[0015] Preferably, the annular gear ring and the driving gear are provided with a protective shell, the protective shell is fixedly connected to a pair of connecting rods, and a long strip opening is reserved at the bottom of the protective shell for the axle of the driving gear to pass through.

[0016] Preferably, the third truss is rotated to install the anchor bolt machine body by a rotating structure, and the rotating structure includes:

[0017] a rotating sleeve comprising a fixed sleeve, a movable sleeve, and a movable sleeve motor; the axes of the fixed sleeve and the movable sleeve coincide and are arranged horizontally; the fixed sleeve is fixedly connected to the third truss; the movable sleeve is electrically connected to the movable sleeve motor; and the movable sleeve rotates relative to the fixed sleeve when driven by the movable sleeve motor;

[0019] Among them, when the rotating frame rotates to a vertical state, the anchor rods sent out by the anchor bolt machine body are perpendicular to the tunnel face; when the rotating frame rotates to a horizontal state and the give way groove engages with the third truss, the anchor rods sent out by the anchor bolt machine body are parallel to the tunnel face.

[0020] The present invention has at least the following beneficial effects:

[0021] First, the present invention realizes sliding on the large gear ring by connecting the installation base with the slider, and rotates the rod feeding cylinder, the first truss, the second truss, and the third truss to cooperate and pull with each other, so as to realize the swing of the third truss at the predetermined positioning point in the horizontal plane, without over-relying on the calculation accuracy of the wireless controller, ensuring the accurate grouting and support of the anchor machine assembly and enhancing the anchoring effect.

[0022] Second, the slider is set in the slide groove of the large gear ring, and the slider motor drives it to slide to different height change positions for grouting or support operations. The mounting base is preferably an acute triangle structure, and its inner side is the mounting surface for mounting the slider, which can be fixedly connected by anchoring, welding, etc. The three hinge points set on the top surface are connected to the components respectively by rotating the sleeve column of the U-shaped turntable. The first truss, the second truss, and the third truss are pulled together, and the rotating rod cylinder provides power. The traction point of the first truss is formed by the extension and shortening of the piston rod. The first hinge point is set at a position close to one end of the first truss. The shorter section rotates with a smaller displacement to make the longer section rotate. The larger displacement pulls the second truss to make a large displacement movement. The hinge point of the second truss and the third truss is close to one end of the third truss. The shorter section rotates with a smaller displacement to make the longer section rotate with a larger displacement, pulling the third truss to make a large displacement movement within a range of 90°. When advance support grouting is required, it is rotated to be parallel to the installation surface. At this time, the first truss and the second truss are 180°. When support is required, it is rotated to be perpendicular to the installation surface. At this time, the second truss coincides with the third truss. The assembly components are mainly composed of mechanical structures. Each truss checks and balances each other. The wireless controller only needs to control the telescopic length of the rotating feed rod cylinder, eliminating the steps of fixed-point positioning calculation, and has better controllability.

[0023] Third, the bolter body includes a control mechanism, a rotating mechanism, a long feed mechanism, a roof mechanism, a sliding assembly, etc. The main steps of grouting and support are drilling. Before drilling, check whether all parts are complete, whether the fasteners are loose, whether the operating mechanisms are flexible, and whether the operation control switch of the host is in the closed position (the cylinder should be retracted to the minimum value). When drilling, operate the feed mechanism handle to put in the drill rod, operate the feed mechanism handle, push the rotary mechanism until the drill bit is close to the coal wall, operate the rotary mechanism to rotate forward and push the handle to advance the feed mechanism, and drill to the designed hole depth. After drilling is completed, exit the feed mechanism, remove the drill rod, put the resin medicine roll into the anchor hole, put the tray on the top plate of the roof mechanism, insert the anchor into the anchor hole, put the nut end of the anchor into the agitator, push the feed handle, push the anchor into the hole, rotate the anchor for the required time, wait for the time required by the medicine bag, tighten the nut, return the drilling rig, retract the support plate, and return the roof mechanism and feed mechanism to their original positions.

[0024] Fourth, a protective plate is set up to prevent external debris from falling and affecting the turnover of each component, and a gap is reserved to facilitate the third truss to swing within a 90° range; the large gear ring is slidably connected to the front section of the main beam to ensure smooth forward movement during grouting; the setting of the gear ring limit sliding structure ensures smooth and precise sliding through double sliding limits. A pair of frames are set front and back, with through holes for the connecting rod to slide through and rolling structures (such as rollers), and limiting structures (such as blocking rings with larger outer diameters). The annular gear ring and the driving gear are located in the same horizontal plane, and the toothed disc of the driving gear is set on the gear shaft. A part of the arc section of the toothed disc is provided with teeth, which mesh with the annular gear ring. The driven gear motor drives the active gear to rotate in one direction. The teeth of the first straight segment and the second straight segment are arranged opposite to each other. When rotating, the active gear alternately engages with the racks of the first straight segment and the second straight segment in turn, driving the large gear ring to move forward and backward. When grouting operation is required, it moves forward and positions, and when support operation is required, it moves backward and positions. The stroke of the large gear ring is limited by the drive of the active gear motor, and the sliding cooperation between the limit groove and the limit block further ensures that the large gear ring moves forward to the predetermined position and retreats to the predetermined position; a protective shell is set to prevent external debris from falling and affecting the turnover of each component, and a reserved opening is convenient for the wheel axle to pass through when the annular gear ring moves.

[0025] Fifth, the setting of the rotating structure enables the anchor bolt machine body to rotate 0-90° directly relative to the third truss. The fixed cylinder is installed with the third truss, and the movable cylinder is rotated by the movable cylinder motor. The fixed cylinder and the movable cylinder can be selected in the form of inner and outer cylinders, or in the form of clamping in sequence. The movable cylinder is fixedly connected to the rotating frame, and the rotation of the movable cylinder drives the rotating frame to rotate. When the rotating frame rotates to a vertical state, the anchor bolt machine body is ready for advance support grouting. When the rotating frame rotates to a horizontal state, the clearance groove cooperates with the third truss, and the anchor bolt machine body is ready for support, which is convenient for the arrangement of multiple components in a narrow space to achieve precise positioning.

[0040] The slider 4 is slidingly set in the slide groove of the large gear ring 2, and the slider motor drives it to slide to different height change positions for grouting operations or support operations. The mounting base 5 is preferably an acute triangle structure, the inner side of which is the mounting surface for mounting the slider 4, which can be fixedly connected by anchoring, welding, etc. The three hinge points set on the top surface can be connected to the components respectively by rotating the sleeve column of the U-shaped turntable. The first truss 62, the second truss 63, and the third truss 64 pull each other, and the rotating rod cylinder 61 provides power. The traction point of the first truss 62 is formed by the extension and shortening of the piston rod. The first hinge point is set at a position close to one end of the first truss 62. The shorter section rotates with a smaller displacement to make the longer section rotate with a larger displacement. , pulling the second truss 63 to make a large displacement movement, the hinge point of the second truss 63 and the third truss 64 is close to one end of the third truss 64, the shorter section rotates a smaller displacement to make the longer section rotate a larger displacement, pulling the third truss 64 to make a large displacement movement within a 90° range, when advance support grouting is required, it is rotated to be parallel to the installation surface, at this time the first truss 62 and the second truss 63 are 180°, when support is required, it is rotated to be perpendicular to the installation surface, at this time the second truss 63 and the third truss 64 coincide with each other, the assembly components are mainly composed of mechanical structures, each truss checks and balances each other, the wireless controller only needs to control the telescopic length of the rotating feed rod cylinder 61, eliminating the steps of fixed-point positioning calculation, and the controllability is better.

[0041] The anchor machine body 1 includes a control mechanism, a rotating mechanism, a long feed mechanism, a roof mechanism, a sliding assembly, etc. The main steps of grouting and support are drilling. Before drilling, check whether all parts are complete, whether the fasteners are loose, whether the operating mechanisms are flexible, and whether the operation control switch of the main machine is in the closed position (the oil cylinder should be retracted to the minimum value). When drilling, operate the feed mechanism handle to put in the drill rod, operate the feed mechanism handle, push the rotating mechanism until the drill bit is close to the coal wall, operate the rotating mechanism to rotate forward and the push handle to push the feed mechanism forward, and drill to the designed hole depth.

[0042] In another technical solution, protective plates are installed above and below the rotating rod feed cylinder 61, the first truss 62, the second truss 63, and the third truss 64. These plates are connected by a sealing plate and have a notch reserved for the rotation of the third truss 64. The protective plates prevent external debris from falling and affecting the rotation of the components, and the notch allows the third truss 64 to swing within a 90-degree range.

[0043] In another technical solution, there are two large gear rings 2, symmetrically distributed on both sides of the main beam front section 3. The large gear rings 2 are arc-shaped, with the top and bottom of the large gear rings 2 slidingly mounted on the top and bottom surfaces of the main beam front section 3. The outer sides of the large gear rings 2 are provided with sliding grooves for the sliding blocks 4. The large gear rings 2 are slidably connected to the main beam front section 3 to ensure smooth forward movement during grouting.

[0044] In another technical solution, the top and bottom of the large gear ring 2 are slidably mounted on the top and bottom surfaces of the main beam front section 3 by a gear ring limiting sliding structure, and the gear ring limiting sliding structure includes:

[0045] A pair of frames 7, which are mounted on the front section 3 of the main beam;

[0046] The gear ring assembly comprises an annular gear ring, a driving gear, and a driving gear motor. The annular gear ring is horizontally arranged and is formed by a front semicircular segment, a first straight segment, a rear semicircular segment, and a second straight segment connected end to end. The middle parts of the outer sides of the front semicircular segment and the rear semicircular segment are movably mounted on a pair of frames 7 through connecting rods. Racks are provided on the inner sides of the first straight segment and the second straight segment, and teeth are provided on a part of the arc section of the outer periphery of the driving gear. The driving gear is point-connected with the driving gear motor. When the driving gear rotates to engage with the rack of the first straight segment, the driving gear rotates to drive the annular gear ring to move forward relative to the pair of frames 7. When the driving gear rotates to engage with the rack of the second straight segment, the driving gear rotates to drive the annular gear ring to move backward relative to the pair of frames 7. The outer side of the first straight segment is fixedly connected to the top or bottom of the large gear ring 2.

[0047] The limiting groove and the limiting block, the limiting groove is arranged on the front section 3 of the main beam, the limiting block is fixedly connected to the top or bottom of the large gear ring 2, the limiting block is slidably arranged in the limiting groove, and the length of the limiting groove is set: when the annular gear ring moves forward or backward to the limit, the limiting block slides to the front end or rear end of the limiting groove respectively.

[0048] In the above technical solution, the setting of the gear ring limiting sliding structure ensures smooth and precise sliding through double sliding limits. A pair of frames 7 are arranged front and back, and have a through hole for the connecting rod to slide through and a rolling structure (such as a roller) and a limiting structure (such as a blocking ring with a larger outer diameter). The annular gear ring and the driving gear are located in the same horizontal plane. The toothed disc of the driving gear is sleeved on the gear shaft. A part of the arc section of the toothed disc is provided with teeth, and the teeth are meshed with the annular gear ring. The driving gear motor drives the driving gear to rotate unidirectionally. The teeth of the first straight segment and the second straight segment are arranged opposite to each other. When rotating, the driving gear alternately meshes with the racks of the first straight segment and the second straight segment, driving the large gear ring 2 to move forward and backward. When grouting operation is required, it moves forward and positions, and when support operation is required, it moves backward and positions. The stroke of the large gear ring 2 is limited by the drive of the driving gear motor, and the sliding cooperation between the limiting groove and the limiting block further ensures that the large gear ring 2 moves forward to the predetermined position and retreats to the predetermined position.

[0049] In another technical solution, the annular gear ring and driving gear are protected by a protective housing fixedly connected to a pair of connecting rods. A long, narrow opening is reserved at the bottom of the housing for the driving gear's axle to pass through. The protective housing prevents external debris from falling and disrupting the rotation of the components, while the reserved opening facilitates the passage of the axle during the movement of the annular gear ring.

[0050] In another technical solution, Figure 4 As shown, the third truss 64 is rotated to install the anchor bolt machine body 1 through a rotating structure, and the rotating structure includes:

[0051] The rotating sleeve 8 includes a fixed sleeve, a movable sleeve, and a movable sleeve motor. The axes of the fixed sleeve and the movable sleeve coincide and are arranged horizontally. The fixed sleeve is fixedly connected to the third truss 64. The movable sleeve is electrically connected to the movable sleeve motor. The movable sleeve rotates relative to the fixed sleeve when driven by the movable sleeve motor.

[0052] The rotating frame 9 is a U-shaped structure. Both ends of the rotating frame 9 are fixed to the moving cylinder. The middle part of the rotating frame 9 is provided with a clearance groove that matches the curvature of the third truss 64. The rotating frame 9 is fixedly connected to the anchor bolt machine body 1.

[0053] Among them, when the rotating frame 9 rotates to a vertical state, the anchor rods sent out by the anchor bolt machine body 1 are perpendicular to the tunnel face. When the rotating frame 9 rotates to a horizontal state and the clearance groove engages with the third truss 64, the anchor rods sent out by the anchor bolt machine body 1 are parallel to the tunnel face.

[0054] In the above technical solution, the setting of the rotating structure enables the anchor bolt machine body 1 to rotate 0-90° directly relative to the third truss 64. The fixed cylinder is installed with the third truss 64, and the movable cylinder is rotated under the drive of the movable cylinder motor. The fixed cylinder and the movable cylinder can be selected in the form of inner and outer cylinders, or in the form of clamping in sequence. The movable cylinder is fixedly connected to the rotating frame 9. The rotation of the movable cylinder drives the rotating frame 9 to rotate. When the rotating frame 9 rotates to a vertical state, the anchor bolt machine body 1 is ready for advance support grouting. When the rotating frame 9 rotates to a horizontal state, the clearance groove cooperates with the third truss 64, and the anchor bolt machine body 1 is ready for support, which is convenient for the arrangement of multiple components in a narrow space to achieve precise positioning.
