Description

Technical Field

[0001] This application relates to the technical field of hoistway drilling equipment, and particularly to a suspended drilling and anchor tightening system.

Background Art

[0002] Hoistway drilling, as the name implies, is to drill a passage such as in the vertical direction. A hoistway is generally a space for the operation of hoisting equipment. In order to realize the stability of the hoisting movement of the hoisting equipment by fixing a frame to the inner wall of the hoistway, holes are drilled in the hoistway and expansion anchors are driven into the inner wall of the hoistway.

[0003] In conventional hoistway drilling equipment, usually, a hoist and a suspension cable cooperate to suspend a drilling device in the hoistway. The swing amplitude during the descent of the suspension cable is large, which not only affects the drilling speed of the side wall of the hoistway, but also affects the drilling accuracy of the hoistway. Therefore, the deviation of the position and orientation of the expansion anchor driven later becomes large, which affects the subsequent fixing of the frame and there is a certain safety risk.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The technical problem to be solved by this application is that the swing amplitude of the suspension cable of the conventional drilling equipment during the descent and the entry into the inner wall of the hoistway is large, which not only affects the drilling speed of the side wall of the hoistway, but also affects the drilling accuracy of the hoistway. Therefore, the deviation of the position and orientation of the expansion anchor driven later becomes large, which affects the subsequent fixing of the frame and there is a certain safety risk. According to this application, a suspended drilling and anchor tightening system is provided.

Means for Solving the Problems

[0005] To solve the technical problem, the technical solution adopted in this application is a suspended drilling and anchor tightening system, and the suspended drilling and anchor tightening system is Including mainframes, Above the main frame, a suspension cable is provided to control the horizontal raising and lowering of the main frame. Support mechanisms are provided on both sides of the main frame in the longitudinal direction to suppress the amplitude of swaying during the raising and lowering of the main frame. The support mechanism is further used to fix the position of the main frame during drilling and anchor tightening by the system. A wall support mechanism is provided on the side of the main frame that is close to the surface to be machined, which engages with the side wall of the elevator shaft. Below the main frame, a drilling and anchor tightening mechanism is provided. A drive mechanism is provided between the main frame and the drilling and anchor tightening mechanism to drive the movement of the drilling and anchor tightening mechanism along the X-axis, Y-axis, and Z-axis.

[0006] To prevent large swings of the drilling and anchoring system within the hoistway, a suspension cable is used to control the system's entry into the hoistway. The support mechanism is used to engage with two opposing side walls of the hoistway, reducing the swing of the drilling and anchoring system as it moves up and down within the hoistway. When the system drills into the side walls of the hoistway and drives in anchors, the support mechanism and the side walls of the hoistway push against each other to fix the position of the main frame, ensuring the stability of drilling and anchoring. The wall support mechanism engages with the work surface of the hoistway, making the movement of the drilling and anchoring system within the hoistway more stable and ensuring a more accurate position of the drilling and anchoring system in a vertically balanced state. The support mechanism, wall support mechanism, drilling and anchoring mounting mechanism, and drive mechanism work together to drill into the work surface of the hoistway so that the drilled holes are perpendicular to the ground, and to drive in the expansion anchors into the holes.

[0007] Furthermore, the support mechanism includes a central plate and a floating plate, The floating plate is provided on the side of the central plate away from the main frame, The central portion of the floating plate and the central plate are hinged together so as to be rotatable around a vertical axis. The central plate is provided with a positioning spring used to limit the oscillation range of the floating plate. The positioning spring is provided between the floating plate and the central plate. Support claws are provided at both ends of the side walls of the floating plate that are away from the central plate. A support ring is provided above or below the support claw. An elastic member is provided between the support ring and the floating plate. The support ring, when driven by the elastic member, has a vertical projection that is outward from the vertical projection of the support claw. The main frame is provided with electric push rods that push the central plates on the two support mechanisms in opposite directions to the sides of the main frame.

[0008] Using electric push rods, the central plates on the two support mechanisms are pushed outwards, bringing them closer to the two opposing side walls of the hoistway, thereby bringing the support wheels and support claws closer to the two side walls of the hoistway. Due to the drive of the elastic member, the vertical projection of the support wheels is outside the vertical projection of the support claws, so when the support wheels contact the side walls of the hoistway, the support claws have not yet contacted the side walls. Due to the action of the elastic member, the support wheels elastically contact the side walls of the hoistway, reducing the amplitude of sway of the drilling and anchoring system within the hoistway, while ensuring free vertical operation and movement of the drilling and anchoring system within the hoistway. When the drilling and anchoring system reaches the drilling position, the electric push rods continue to bring the central plates closer to both side walls of the hoistway and bring the support claws into contact with the side walls of the hoistway, ensuring that the drilling and anchoring system can be stably supported, thereby ensuring drilling stability.

[0009] Furthermore, since the walls of the elevator shaft have some irregularities and the opposing walls are never perfectly parallel, the central plate and the floating plate are both U-shaped in order to ensure that the support wheels / support claws are in close contact with the elevator shaft walls. The inner diameter of the floating plate is slightly larger than the outer diameter of the central plate. The central plate partially extends into the U-shaped groove of the floating plate, A U-shaped connecting frame is provided on the outside of the central plate. Within the connecting frame, a link pin that fits into the floating plate is provided vertically.

[0010] Furthermore, in order to improve the stability of the connection between the support mechanism and the main frame, the main frame is provided with at least one set of telescopic rod bush assemblies. The aforementioned telescopic rod bush assembly includes a slide rod and a slide bush, The axes of the slide rod and the slide bush are parallel to the axis of the electric push rod. The slide rods are slidably connected to both ends of the slide bush. The ends of the two slide rods that are not connected to the slide bushings are each fixed to the central plates of the two support mechanisms.

[0011] Furthermore, the wall support mechanism includes two wall support wheel assemblies spaced apart, The wall support wheel assembly includes an L-shaped frame and a wall support wheel. The L-shaped frame is rotatably connected at one end to the wall support ring, and rotatably connected horizontally to the main frame at the other end. The height of the rotation center of the wall support wheel is lower than the height of the rotation center between the L-shaped frame and the main frame.

[0012] The wall support wheel is provided on the side close to the machining target surface of the lifting path of the main frame. To enable the wall support wheel to rotate freely by 360°, the wall support wheel is rotationally connected to the main frame via an L-shaped frame. The wall support wheel is vertically provided by gravity and engages with the machining target surface of the lifting path to ensure a more accurate drilling position in the vertical equilibrium state of the drilling and anchor fastening system.

[0013] Furthermore, the drilling and anchor fastening mechanism includes an equipment frame, a drilling drill provided on the equipment frame, and a hammer, The output ends of the drilling drill and the hammer are provided with their axes parallel and facing in opposite directions.

[0014] Furthermore, the drive mechanism includes a first slide rail, a second slide rail, and a rotating shaft. The first slide rail is provided below the main frame along the X-axis. A first slider is slidably connected to the first slide rail. On one side of the first slide rail, a guide screw and a first motor for reciprocally sliding the first slider along the X-axis are provided. The second slide rail is provided at the lower end of the first slider along the Y-axis. A second slider is slidably connected to the second slide rail. On one side of the second slide rail, a guide screw and a second motor for reciprocally moving the second slider along the Y-axis are provided. The rotating shaft is provided along the Z-axis, with its upper end rotatably connected to the second slider and its lower end rotatably connected to the equipment frame. A third motor for controlling the rotation of the equipment frame around the rotating shaft is transmissionally connected to the second slider.

[0015] Furthermore, a rebar detector is further provided on the equipment frame. The rebar detector is provided with a motor guide screw for controlling the reciprocating movement of the rebar detector in the Z-axis. The height of the rebar detector is adjusted by the motor guide screw. The rebar detector measures the position and height of the rebar within the processing target surface of the lifting path, and in cooperation with the suspension cable that controls the height of the main frame, the drilling drill is drilled at a position where there is no rebar.

[0016] Furthermore, an anchor supply assembly is provided on the side of the second slide rail away from the drilling target wall. The anchor supply assembly includes a sprocket and a chain. The rotation axis of the sprocket is provided in the horizontal direction. The chain is wound around the sprocket. A plurality of supply units are provided at intervals on the outer wall surface of the chain. The supply unit includes two anchor locking plates provided facing away from each other. The expansion anchor is engaged within the anchor locking plate such that its axis is parallel to the axis of the sprocket. A magnet for attracting the expansion anchor is provided between the two anchor locking plates of the supply unit. A supply arrival position switch for detecting the expansion anchor is provided on one side of the highest point of the sprocket. On one side of the supply arrival position switch, a payout assembly is provided for paying out the expansion anchor from the anchor locking plate so that the impact hammer can easily take out the expansion anchor.

[0017] One expansion anchor is manually placed in each supply unit beforehand, and the expansion anchor is secured by two anchor locking plates and a magnet. The highest point of the sprocket is used as the supply point, and the expansion anchor is supplied by rotating the chain in the fixing direction via the sprocket. The supply arrival position switch is an infrared sensor, and when the supply arrival position switch detects the expansion anchor, the motor on the sprocket stops rotating, and the dispensing assembly is used to dispensing the expansion anchor away from the magnet by the anchor locking plate 24 so that the striking hammer can easily pick up and supply the expansion anchor. By repeating the above, the expansion anchor can be supplied automatically.

[0018] Furthermore, in order to dispense the expansion anchor from the anchor locking plate, the dispensing assembly includes a dispensing plate and a dispensing motor. The axis of the output end of the aforementioned dispensing motor is parallel to the axis of the aforementioned sprocket. Two of the dispensing plates are provided parallel to each other at the output terminal of the dispensing motor. The two aforementioned discharge plates are provided on both sides of the sprocket. The discharge plate is provided with an arc-shaped groove that engages with the expansion anchor.

[0019] Furthermore, in order to control the movable range of the dispensing plate, an initial dispensing position switch and a dispensing arrival position switch are provided on one side of the dispensing motor. When the dispensing plate contacts the initial dispensing position switch, the arc-shaped groove is positioned below the supply arrival position switch. When the dispensing plate contacts the dispensing arrival position switch, the arc-shaped groove is positioned above the supply arrival position switch.

[0020] The initial dispensing position switch and the final dispensing position switch are microswitches. When the dispensing plate makes contact with the microswitch, it is confirmed that the dispensing plate has rotated to a predetermined position, and the power to the dispensing motor is cut off in an appropriate manner.

[0021] Furthermore, the main frame further includes a measurement mechanism comprising multiple distance sensors, controllers, and a laser plumb bob, The distance sensor, the laser plumb bob, the first motor, the second motor, and the third motor are all connected to the controller.

[0022] A laser plumb bob is used to detect whether the system is in a vertical equilibrium state. In this drilling and anchoring system, the hoist and suspension cable work together to keep the drilling and anchoring system in a vertical equilibrium state, so that it is always perpendicular to the ground under the action of the hoist and suspension cable. In this state, the distance of the hoistway to the work surface is measured by the distance sensor, and then the support claws are extended to fix the position of the main frame. At this time, the difference between the distance of each distance sensor and the work surface is calculated and used to compensate for the drilling position so that the hole to be drilled is perpendicular to the ground.

[0023] The beneficial effects of this invention are as follows: With the suspended drilling and anchoring system provided by this invention, the support mechanism, wall support mechanism, drive mechanism, and drilling and anchoring mechanism provided on the main frame cooperate, and when the system is in a vertical equilibrium state, a hole perpendicular to the ground is drilled in the wall of the elevator shaft, and the position of the expansion anchor driven into the hole is precise, thereby ensuring the structural strength of the frame fixed to the inner wall of the elevator shaft and ensuring the stability of the elevator's movement.

[0034] On the side of the second slide rail 17 away from the wall to be drilled, an anchor supply assembly is provided, the anchor supply assembly includes a sprocket 22 and a chain 23, the sprocket 22 to which a supply motor 34 is movably connected, the rotation axis of the sprocket 22 is provided horizontally, the chain 23 is wound around the sprocket 22, a plurality of supply units are provided at intervals on the outer wall surface of the chain 23, the supply unit includes two anchor locking plates 24 provided facing each other, and expansion anchor 2 6 is engaged within the anchor locking plate 24 such that its axis is parallel to the axis of the sprocket 22, a magnet 25 for attracting the expansion anchor 26 is provided between the two anchor locking plates 24 of the supply unit, a supply reach position switch 27 for detecting the expansion anchor 26 is provided on one side of the highest point of the sprocket 22, and a dispensing assembly is provided on one side of the supply reach position switch 27 for dispensing the expansion anchor 26 from the anchor locking plate 24 so that the striking hammer 2-3 can easily take out the expansion anchor 26.

[0035] The dispensing assembly includes a dispensing plate 28 and a dispensing motor 29, the axis of the output end of the dispensing motor 29 being parallel to the axis of the sprocket 22, two dispensing plates 28 being provided parallel to each other at the output end of the dispensing motor 29, the two dispensing plates 28 being provided on both sides of the sprocket 22, and the dispensing plates 28 are provided with arc-shaped grooves 28-1 that engage with the expansion anchor 26.

[0036] On one side of the dispensing motor 29, there is a dispensing initial position switch 30 and a dispensing arrival position switch 31. When the dispensing plate 28 contacts the dispensing initial position switch 30, the arc-shaped groove 28-1 is positioned below the supply arrival position switch 27, and when the dispensing plate 28 contacts the dispensing arrival position switch 30, the arc-shaped groove 28-1 is positioned above the supply arrival position switch 27.

[0037] The system further includes a measurement mechanism comprising a plurality of distance sensors 32, a controller, and a laser plumb bob 33, all of which are connected to the controller.

[0038] Work procedure The system is controlled to descend using a hoist and suspension cable 3 and enter the elevator shaft, and the two wall support wheels 15 on the main frame 1 engage with the wall surface to be worked on in the elevator shaft. The electric push rods 11 on both sides of the main frame 1 protrude and push the two central plates 4 to the sides. This brings the support wheels 7 and support claws 6 close to the walls on both sides of the wall surface to be worked on in the elevator shaft. When the support wheels 7 are in contact with the side wall of the elevator shaft and the support claws 6 are not in contact with the side wall of the elevator shaft, the spring-loaded hinges elastically bring the support wheels 7 into contact with the side wall of the elevator shaft. This ensures the system's free vertical movement while simultaneously preventing the system from swaying significantly in the front-back and side-to-side directions within the well.

[0039] When the system reaches the drilling height, the rebar detector 21 is used to check whether or not rebar is present in the wall to be drilled. If rebar is present, the height of the system must be readjusted using the suspension cable 3 and hoist. The system is in a vertically balanced state within the elevator shaft and is always perpendicular to the ground. In this state, the distance sensor 32 is used to take the first measurement of the distance to the elevator shaft wall. Next, the support claws 6 are extended and locked to the walls on both sides, and at this time, the distance sensor 32 is used to take the second measurement of the distance to the elevator shaft wall. The controller calculates the difference between the first and second measurements and compensates the drilling drill 2-2. The first motor, second motor, and third motor on the drive mechanism cooperate with each other to adjust the position of the drilling drill 2-2 so that the hole drilled by the drilling drill 2-2 is perpendicular to the ground.

[0040] After drilling is complete, the expansion anchor 26 is supplied using the sprocket 22 and chain 23. When the supply arrival position switch 27 detects that the expansion anchor 26 has reached its position, the supply motor 34 on the sprocket 22 stops rotating, and the discharge motor 29 rotates the discharge plate 28. As the discharge plate 28 rotates, it dispenses the expansion anchor 26 from the anchor locking plate 24. When the supply arrival position switch 31 senses the discharge plate 28, the discharge plate 28 stops rotating. At this time, the striking hammer 2-3 approaches and removes the expansion anchor 26 from the discharge plate 28, and the discharge motor 29 rotates the discharge plate 28 in the reverse direction. When the discharge initial position switch 30 senses the discharge plate 28, the discharge plate 28 stops rotating, and the sprocket 22 waits for the next expansion anchor 26 to be sent to the supply arrival position switch 27. This process is repeated until the automatic supply of the expansion anchor 26 is complete.

[0041] The controller works in cooperation with the first motor, second motor, and third motor on the drive mechanism to adjust the position of the striking hammer 2-3, and after the striking hammer 2-3 has taken out the expansion anchor 26, it drives the expansion anchor 26 on the striking hammer 2-3 into the hole drilled by the drilling drill 2-2.
