Description

A suspended drilling and screwing system Technical Field

[0001] The present invention relates to the technical field of well drilling equipment, and in particular to a suspended drilling and screwing system. Background Art

[0002] As the name suggests, shaft drilling is a similar channel in the vertical direction. The shaft is generally a space for the operation of lifting equipment. Holes are drilled in the shaft to allow expansion bolts to be driven into the inner wall of the shaft so that the bracket can be subsequently fixed to the inner wall of the shaft to provide stability for the lifting movement of the lifting equipment.

[0003] Existing shaft drilling equipment usually uses a winch and a sling to lift the drilling equipment into the shaft. Due to the large shaking amplitude of the sling during the descent, it not only affects the speed of drilling holes in the shaft side wall, but also affects the accuracy of shaft drilling. This causes a large deviation in the position and direction of the expansion screws subsequently inserted, affecting the fixation of the subsequent bracket, thus posing certain safety hazards.

[0004] Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the shortcomings of the prior art in which the drilling equipment shakes greatly during its descent into the shaft, which not only affects the speed of drilling holes in the shaft side walls, but also affects the accuracy of drilling holes in the shaft, resulting in large deviations in the position and direction of the expansion screws subsequently driven in, affecting the fixation of the subsequent brackets, thereby posing certain safety hazards, the present invention provides a suspended drilling and screwing system.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a suspended drilling and screwing system, including a main frame, a sling for controlling the horizontal lifting of the main frame is provided above the main frame, and support mechanisms are provided on both sides of the length direction of the main frame. The support mechanisms are used to prevent the main frame from shaking greatly during the lifting process. The support mechanisms are also used to fix the position of the main frame when the system is drilling and screwing. The side of the main frame close to the surface to be processed is provided with a wall support mechanism that cooperates with the side wall of the well, and a drilling and screwing mechanism is provided below the main frame. A driving mechanism for driving the drilling and screwing mechanism to move along the X-axis, move along the Y-axis, and rotate along the Z-axis is provided between the main frame and the drilling and screwing mechanism.

[0007] The drilling and screwing system is controlled to enter the shaft by a sling. In order to prevent the drilling and screwing system from shaking greatly in the shaft, the support mechanism is used to cooperate with the two side walls of the shaft that are arranged opposite to each other. On the one hand, it reduces the shaking amplitude of the drilling and screwing system when it moves up and down in the shaft. On the other hand, when the system drills holes and hammers screws into the side walls of the shaft, the support mechanism and the side walls of the shaft are pressed tightly to fix the position of the main frame, ensuring the stability of the drilling and screwing. The wall support mechanism cooperates with the surface to be processed of the shaft, making the drilling and screwing system more stable when moving up and down in the shaft, and making the position of the drilling and screwing system more accurate under the heavy hammer state. The support mechanism, wall support mechanism, drilling and screwing mechanism and driving mechanism cooperate with each other to drill holes in the surface to be processed of the shaft and hammer expansion screws into the holes to ensure that the holes are perpendicular to the ground.

[0008] Furthermore, the supporting mechanism includes an intermediate plate and a floating plate, the floating plate being arranged on a side of the intermediate plate away from the main frame, the middle position of the floating plate and the intermediate plate being hinged in the vertical direction, the intermediate plate being provided with a limit spring for limiting the swinging amplitude of the floating plate, the limit spring being arranged between the floating plate and the intermediate plate, support claws being provided at both ends of the side wall of the floating plate away from the intermediate plate, support wheels being provided above or below the support claws, an elastic member being provided between the support wheel and the floating plate, the vertical projection of the support wheel being driven by the elastic member being outside the vertical projection of the support claws, and an electric push rod being provided on the main frame for pushing the intermediate plates on the two supporting mechanisms in opposite directions toward the two sides of the main frame.

[0009] The middle plates on the two support mechanisms are pushed to both sides by an electric push rod, so that the middle plates are close to the two side walls of the well set opposite to each other, thereby driving the supporting wheels and supporting claws to approach the two side walls of the well; because the vertical projection of the supporting wheels is outside the vertical projection of the supporting claws under the drive of the elastic member, when the supporting wheels contact the side walls of the well, the supporting claws have not yet contacted the side walls of the well, and the elastic member makes the contact between the supporting wheels and the side walls of the well elastic, ensuring that the punching and screwing system can move up and down freely in the well, while reducing the shaking amplitude of the punching and screwing system in the well; when the punching and screwing system reaches the punching position, the electric push rod continues to drive the middle plate close to the two side walls of the well, making the supporting claws contact with the side walls of the well, ensuring that the punching and screwing system can be stably supported and the drilling is stable.

[0010] Furthermore, the shaft wall itself will be somewhat uneven, and the relatively arranged walls will not be absolutely parallel. In order to make the support wheel / support claw close to the shaft wall, the intermediate plate and the floating plate are both U-shaped plates, the inner diameter of the floating plate is slightly larger than the outer diameter of the intermediate plate, and the intermediate plate partially extends into the U-shaped groove of the floating plate. A U-shaped connecting frame is provided on the outside of the intermediate plate, and a connecting pin that cooperates with the floating plate is vertically provided in the connecting frame.

[0011] Furthermore, in order to improve the stability of the connection between the support mechanism and the main frame, at least one set of sleeve assemblies is provided on the main frame, and the sleeve assembly includes a sliding rod and a sliding sleeve. The axes of the sliding rod and the sliding sleeve are parallel to the axis of the electric push rod. The sliding rods are slidably connected at both ends of the sliding sleeve, and the ends of the two sliding rods away from the sliding sleeve are fixedly connected to the middle plates on the two support mechanisms respectively.

[0012] Furthermore, the wall supporting mechanism includes two wall supporting wheel assemblies arranged at intervals, and the wall supporting wheel assembly includes an L-shaped frame and a wall supporting wheel. One end of the L-shaped frame is rotatably connected to the wall supporting wheel, and the other end is rotatably connected to the main frame in the horizontal direction. The height of the rotation center of the wall supporting wheel is lower than the height of the rotation center between the L-shaped frame and the main frame.

[0013] The supporting wheel is set on the side of the main frame close to the surface to be processed in the shaft. The supporting wheel is rotatably connected to the main frame through an L-shaped frame, so that the supporting wheel can rotate freely 360°. The supporting wheel is set vertically under the action of gravity and cooperates with the surface to be processed in the shaft to ensure that the drilling position of the drilling and screwing system is more accurate under the heavy hammer state.

[0014] Furthermore, the drilling and screwing mechanism includes a frame and a drilling drill and a percussion hammer arranged on the frame, and the axes of the output ends of the drilling drill and the percussion hammer are parallel and arranged in opposite directions.

[0015] Furthermore, the driving mechanism includes a first slide rail, a second slide rail and a rotating shaft, the first slide rail is arranged below the main frame along the X-axis, the first slide rail is slidably connected to the first slider, one side of the first slide rail is provided with a screw and a first motor for driving the first slider to slide back and forth along the X-axis, the second slide rail is arranged at the lower end of the first slider along the Y-axis, the second slide rail is slidably connected to the second slider, one side of the second slide rail is provided with a screw and a second motor for driving the second slider to move back and forth along the Y-axis, the rotating shaft is arranged along the Z-axis, the upper end is rotatably connected to the second slider, and the lower end is rotatably connected to the frame, and the second slider is transmission-connected to the third motor for controlling the frame to rotate along the rotating shaft.

[0016] Furthermore, the frame is equipped with a rebar detector, which is equipped with a motor screw for controlling the rebar detector's back-and-forth movement on the Z-axis. The motor screw adjusts the height of the rebar detector, which detects the height of the rebar within the surface to be processed in the shaft. This, in conjunction with the sling that controls the height of the main frame, allows the drill to drill holes in locations where there are no rebar.

[0017] Furthermore, a screw feeding assembly is provided on the side of the second slide rail away from the wall to be punched, and the screw feeding assembly includes a sprocket and a chain, the rotation center of the sprocket is arranged in the horizontal direction, a chain is wound around the sprocket, and a plurality of feeding units are provided at intervals on the outer wall of the chain, the feeding unit includes two screw clamps arranged opposite to each other, the expansion screw is clamped in the screw clamp and the axis is parallel to the sprocket axis, a magnet for attracting the expansion screw is provided between the two screw clamps of the feeding unit, a loading position switch for monitoring the expansion screw is provided on one side of the highest point of the sprocket, and a feeding assembly for pushing the expansion screw out of the screw clamp to facilitate the hammer to grab the expansion screw is provided on one side of the loading position switch.

[0018] An expansion screw is manually placed in each loading unit in advance, secured with two screw clamps and magnets. The highest point of the sprocket is used as the loading point, and the sprocket drives the chain to rotate in a fixed direction, thereby loading the expansion screw. The loading position switch is an infrared sensor. When the loading position switch detects the expansion screw, the motor on the sprocket stops, and the prying assembly is used to pry the expansion screw out of the screw clamp, away from the magnet, so that the hammer can grab the expansion screw, completing the loading. This process is repeated to automatically load the expansion screws.

[0019] Furthermore, in order to push the expansion screw out of the screw clamp, the pushing assembly includes a pushing plate and a pushing motor. The output end axis of the pushing motor is parallel to the sprocket axis. Two parallel pushing plates are provided on the output end of the pushing motor. The two pushing plates are provided on both sides of the sprocket. The pushing plates are provided with arc grooves that cooperate with the expansion screws.

[0020] Furthermore, in order to control the range of movement of the material diverter plate, a material diverter initial position switch and a material diverter in-place switch are provided on one side of the material diverter motor. When the material diverter plate contacts the material diverter initial position switch, the arc groove is arranged below the material loading in-place switch. When the material diverter plate contacts the material diverter in-place switch, the arc groove is arranged above the material loading in-place switch.

[0021] The material initial position switch and the material in-position switch are micro switches. The material shifting plate contacts the micro switch to confirm whether the material shifting plate is rotated into position, thereby timely cutting off the power to the material shifting motor.

[0022] Furthermore, it also includes a measuring mechanism, which includes several distance sensors, a controller and a laser plumb line arranged on the main frame, and the distance sensors, laser plumb line, first motor, second motor and third motor are all connected to the controller circuit.

[0023] The laser plumb line is used to detect whether the system is in a heavy hammer state; the drilling and screwing system cooperates with the winch and the sling to put the entire drilling and screwing system in a heavy hammer state, ensuring that the drilling and screwing system is always perpendicular to the ground under the action of the winch and the sling. In this state, the distance between the distance sensor and the surface to be processed in the shaft is detected, and then the support claw is extended to lock the position of the main frame. At this time, the difference between the distance between the distance sensor and the surface to be processed and the distance between them is calculated, and it is compensated to the drilling position to ensure that the hole is perpendicular to the ground.

[0024] The beneficial effects of the present invention are as follows: the present invention provides a suspended punching and screwing system, which adopts a supporting mechanism, a wall supporting mechanism, a driving mechanism and a punching and screwing mechanism arranged on the main frame to cooperate with each other. When the system is in a heavy hammer state, holes perpendicular to the ground are punched on the wall of the well, so that the expansion screws hammered into the holes are accurately positioned, thereby ensuring the structural strength of the bracket fixed on the inner wall of the well and ensuring the stability of the lifting movement of the lifting equipment.

[0048] It also includes a measuring mechanism, which includes several distance sensors 32, a controller and a laser plumb line 33 arranged on the main frame 1. The distance sensors 32, the laser plumb line 33, the first motor, the second motor and the third motor are all connected to the controller circuit.

[0049] Working process:

[0050] The system is controlled by the winch and the sling 3 to descend into the shaft. The two wall-supporting wheels 15 on the main frame 1 cooperate with the wall surface to be processed in the shaft. The electric push rods 11 on both sides of the main frame 1 extend to push the two middle plates 4 to both sides, thereby driving the supporting wheels 7 and the supporting claws 6 to approach the walls on both sides of the wall surface to be processed in the shaft. When the supporting wheels 7 abut against the side walls of the shaft and the supporting claws 6 have not yet contacted the side walls of the shaft, the spring hinges make the supporting wheels 7 elastically contact the side walls of the shaft, ensuring the free movement of the system up and down while preventing the system from shaking significantly from front to back and left to right in the shaft.

[0051] When the system reaches the drilling height, the steel bar detector 21 is used to detect whether there are steel bars in the wall to be drilled. If there are steel bars, the sling 3 and the winch need to readjust the system height. The system is in a heavy hammer state in the shaft and is always perpendicular to the ground. In this state, the distance sensor 32 is used to measure the distance to the shaft wall for the first time, and then the support claw 6 is extended and locked with the walls on both sides. At this time, the distance sensor 32 measures the distance to the shaft wall for the second time, and the controller calculates the difference from the first measurement and compensates it to the drill 2-2. The first motor, the second motor and the third motor on the drive mechanism cooperate with each other to adjust the position of the drill 2-2 to ensure that the hole drilled by the drill 2-2 is perpendicular to the ground.

[0052] After punching the hole, the expansion screw 26 is loaded through the sprocket 22 chain 23. When the loading in place switch 27 detects that the expansion screw 26 is in place, the loading motor 34 on the sprocket 22 stops rotating, and the feeding motor 29 drives the feeding plate 28 to rotate. During the rotation of the feeding plate 28, the expansion screw 26 in the screw clamping plate 24 is pulled out. When the feeding in place switch 31 senses the feeding plate 28, the feeding plate 28 stops rotating. At this time, the hammer 2-3 approaches and removes the expansion screw 26 on the feeding plate 28. The feeding motor 29 drives the feeding plate 28 to rotate in the opposite direction. When the feeding initial position switch 30 senses the feeding plate 28, the feeding plate 28 stops rotating, waiting for the sprocket 22 to send the next expansion screw 26 to the loading in place switch 27, and so on, to complete the automatic loading of the expansion screw 26.

[0053] The controller cooperates with the first motor, the second motor and the third motor on the driving mechanism to adjust the position of the percussion hammer 2-3. After the percussion hammer 2-3 removes the expansion screw 26, the expansion screw 26 on the percussion hammer 2-3 is hammered into the hole punched by the punch drill 2-2.
