Description

Technical Field

[0001] This invention relates to the field of drilling equipment, and in particular to a drilling, anchoring and injection integrated trolley. Background Technology

[0002] Anchor bolt support is a reinforcement method used in surface engineering projects such as slopes and deep foundation pits, as well as in underground chamber construction such as tunnels and mining areas. Anchor bolts made of metal, wood, polymer, or other materials are driven into pre-drilled holes in the surface rock or the rock mass surrounding the chamber. Utilizing the special structure of the head and body of the bolt and the tail support plate, or relying on bonding, the anchor bolts combine with the surrounding rock to alter its mechanical state, forming a unified and stable rock band around the tunnel. The combined action of the anchor bolts and the surrounding rock produces a suspension effect, a composite beam effect, and a reinforcement effect, thus achieving the purpose of support.

[0003] Currently, the technology level, equipment, and domestic production of rapid construction equipment for soft rock tunnels in my country's railway and highway construction are still in the early stages of mechanized tunnel construction. Anchor bolt installation technology is outdated, relying heavily on manual drilling, manual pushing, and manual grouting. Anchor bolt construction remains largely manual, time-consuming, complex, and poses significant safety hazards. Therefore, existing technologies generally employ automated equipment, such as the tunnel drilling-anchoring-grouting integrated trolley with publication number CN114837712B and the double-arm, basket-type drilling-anchoring integrated anchor bolt trolley with publication number CN223344072U.

[0004] However, the existing integrated drilling, anchoring and grouting trolley still has shortcomings in positioning accuracy, especially before and after drilling. Due to the vibration during drilling, the propulsion beam will shift to a certain extent after the drill rod is withdrawn after drilling is completed, and the operators cannot know the offset in time. This offset will not only cause friction between the drill rod and the drill hole when withdrawing the rod, but also cause errors in subsequent grouting and anchor bolt insertion, often requiring repositioning and seriously reducing construction efficiency. Summary of the Invention

[0005] The core of this invention lies in addressing the problem in existing technologies where the shift of the propulsion beam after drilling is not immediately apparent to operators. This is achieved by monitoring the shift of the propulsion beam before and after drilling. Furthermore, the invention measures the shift and provides operators with intuitive adjustment instructions.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A drilling, anchoring and grouting integrated trolley includes a chassis system. The chassis system includes a front frame, a rear frame articulated with the front frame, a front drive axle mounted on the front frame, a rear drive axle mounted on the rear frame, a drive shaft connecting the front drive axle and the rear drive axle, a gearbox mounted on the rear frame and connected to the drive shaft, an expansion axle support leg mounted on the front frame, and a rear support leg mounted on the rear frame. A cab is mounted on the front frame, and a working arm and a basket arm are mounted on both sides of the front frame on the cab. An electrical control box is mounted on the rear frame, and a grouting machine is mounted at the rear of the rear frame. A floating monitor is fixedly connected to the end of the working arm, and an air pump is installed below the floating monitor. The air pump is connected to the floating monitor through an air supply pipe, and an air release pipe is also connected to the air supply pipe. An air release valve is installed at the air outlet of the air release pipe.

[0008] Furthermore, the boom includes a boom connecting seat 1, a telescopic boom 1 hinged to the boom connecting seat 1, a luffing cylinder 1 hinged between the boom connecting seat 1 and the telescopic boom 1, a swing frame mounted on the output end of the telescopic boom 1, and a push beam mounted on the swing frame. The swing frame includes a motor rotatable base, a rotary motor 1 and a rotary motor 2 respectively installed at the upper and lower ends of the motor rotatable base, a frame installed on the rotary motor 1, a push beam connecting seat 1 and a push beam connecting seat 2 installed at both ends of the frame, a feed cylinder installed on the side of the frame near the push beam connecting seat 1, a swing cylinder installed on the frame below the push beam connecting seat 2, a top plate cylinder installed on the side of the frame near the push beam connecting seat 2, and a top plate installed at the output end of the top plate cylinder; The propulsion beam includes a rock drill propulsion cylinder, a rock drill connected to the output end of the rock drill propulsion cylinder, a power head propulsion cylinder, a power head assembly connected to the output end of the power head propulsion cylinder, an anchor bolt magazine assembly installed on one side of the power head assembly, an anchor bolt gripper located between the power head assembly and the anchor bolt magazine assembly, an anchor injection frame located between the rock drill and the power head assembly, and a resin roll installed on the anchor injection frame; The suspended platform arm includes a boom connecting seat 2, a telescopic boom 2 hinged to the boom connecting seat 2, a luffing cylinder 2 and a synchronizing cylinder hinged between the boom connecting seat 2 and the telescopic boom 2, a suspended platform connecting seat installed on the output end of the telescopic boom 2, a suspended platform installed on the suspended platform connecting seat, and a pitching cylinder hinged between the suspended platform connecting seat and the suspended platform.

[0009] Furthermore, the center points of the rock drill, power head assembly, and anchor injection frame are set at the same center, and the three can swing within a range of ±27°.

[0010] Preferably, a floating monitor is fixedly connected to the end of the rock drill, and an air pump is installed at the lower end of the rock drill. The air pump is connected to the floating monitor through an air supply pipe, and an air release pipe is also connected to the air supply pipe. An air release valve is installed at the air outlet of the air release pipe.

[0011] Furthermore, the floating monitor includes a fixed base, an inflatable base, and a floating base. The inner wall of the fixed base has a ventilation cavity communicating with the interior of the inflatable base. The interior of the inflatable base is equipped with multiple horizontally symmetrically distributed connecting rods, and both ends of the connecting rods are fixedly connected to hinged balls. Two hinged balls are respectively movably embedded in the inner walls of the fixed base and the floating base. The inner wall of the fixed base has an inlay groove that matches the hinged balls, and the inner wall of the inlay groove is equipped with a thin-film pressure sensor. The side wall of the hinged ball is fixedly connected to a pressure head that contacts the thin-film pressure sensor. An alarm connected to the signal of the thin-film pressure sensor is also installed in the cab.

[0012] Furthermore, a protective pad is fixedly connected to the outer surface of the thin-film pressure sensor, and the protective pad is made of elastic and wear-resistant material.

[0013] Furthermore, the inflatable base is made of flexible material, while the connecting rods and articulated balls are made of high-strength rigid material.

[0014] Furthermore, the side wall of the floating seat is also fixedly connected with multiple evenly distributed positioning cones. The positioning cones include a corrugated telescopic cylinder and a cone head. The corrugated telescopic cylinder is made of a highly elastic material, and the cone head is made of an alloy material.

[0015] Optionally, the corrugated telescopic cylinder has a hollow structure, and the inner wall of the floating seat has a second ventilation chamber that communicates with the corrugated telescopic cylinder, and a solenoid valve is installed at the air inlet of the second ventilation chamber.

[0016] Furthermore, an adjustment indicator connected to the diaphragm pressure sensor signal is installed in the cab. The adjustment indicator includes a circular graphic display, and the center point of the graphic display corresponds to the starting point of the pressure head. The graphic display is represented by a line connecting the center point of the starting point and the offset point.

[0017] Compared with the prior art, the advantages of this invention are: (1) The working arm and the basket arm of this scheme have a unique telescopic arm structure, a large working range, no jamming, no abnormal noise, a large adjustable angle of the swing frame, and the push beam can be used for rod connection. The joint structure is stable, flexible, quick and accurate in positioning, simple to operate, and suitable for drilling and anchoring operations under multiple working conditions.

[0018] (2) By adding an offset monitoring device on the top plate to monitor the offset of the propulsion beam before and after drilling, the operators can be informed in time. Compared with the existing technology that only discovers the offset after the impact, it can be discovered in advance and prevented proactively, ensuring the smooth implementation of subsequent grouting and anchor bolt installation. Moreover, the offset direction and offset amount can be presented to the operators in an intuitive form, which is convenient for adjustment. Compared with the existing technology of manual visual adjustment, it can effectively improve efficiency and safety. Attached Figure Description

Detailed Implementation

[0021] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0022] First implementation method: Please see Figure 1 , Figure 2 A drilling, anchoring, and injection integrated trolley includes a chassis system 1. The chassis system 1 includes a front frame 101, a rear frame 102 hinged to the front frame 101, a front drive axle 103 mounted on the front frame 101, a rear drive axle 104 mounted on the rear frame 102, a drive shaft 105 connecting the front drive axle 103 and the rear drive axle 104, a gearbox 106 mounted on the rear frame 102 and connected to the drive shaft 105, an extended axle support leg 107 mounted on the front frame 101, and a rear support leg 108 mounted on the rear frame 102. The front and rear frames are hinged to ensure that the trolley can operate quickly, safely, and flexibly in narrow tunnels. Please see Figure 1The cab 2 is mounted on the front frame 101, and the working arm 3 and the basket arm 4 are mounted on both sides of the cab 2. The electrical control box 5 is mounted on the rear frame 102, and the grouting machine 6 is mounted at the rear of the rear frame 102. The trolley adopts a dual power source control system. When the chassis is moving, it is driven by an internal combustion engine. When the working arm 3 and the basket arm 4 are in working condition, they are driven by an external power source. The internal combustion engine and the external power source cannot be used at the same time. Please see Figure 3 The boom 3 includes a boom connecting seat 301, a telescopic boom 302 hinged to the boom connecting seat 301, a luffing cylinder 303 hinged between the boom connecting seat 301 and the telescopic boom 302, a swing frame 304 mounted on the output end of the telescopic boom 302, and a push beam 305 mounted on the swing frame 304. The boom 3 adjusts the overall pitch and swing range through the luffing cylinder 303. Its pitch range is -30° to +60°, and its swing range is -45° to +45°. The push beam 305 slides and feeds on the swing frame 304. The maximum feed of the push beam 305 is 1800mm. Please see Figure 4 The swing frame 304 includes a motor swivel base 3041, a rotary motor 3042 and a rotary motor 3043 respectively mounted on the upper and lower ends of the motor swivel base 3041, a frame mounted on the rotary motor 3042, a push beam connecting seat 3044 and a push beam connecting seat 3045 mounted on both ends of the frame, a feed cylinder 3046 mounted on the side of the frame near the push beam connecting seat 3044, a swing cylinder 3047 mounted on the frame below the push beam connecting seat 3045, a top plate cylinder 3048 mounted on the side of the frame near the push beam connecting seat 3045, and a top plate 3049 mounted on the output end of the top plate cylinder 3048. The swing frame 304 adopts a dual 360° rotary motor structure, with the rotary motor 3042 carrying... The propulsion beam 305 rotates around the motor axis, and the rotary motor 3043 drives the propulsion beam 305 to rotate around the boom, so that the propulsion beam 305 can approach the working surface at any angle. After approaching the working surface, the top plate cylinder 3048 extends the top plate 3049 and the swing frame 304. The two ends of the feed cylinder 3046 are respectively connected to the propulsion beam connecting seat 3044 and the propulsion beam 305. When the feed cylinder 3046 extends, the propulsion beam 305 retracts. Conversely, when the feed cylinder 3046 retracts, the propulsion beam 305 extends. The swing cylinder 3047 drives the propulsion beam 305 to swing left and right within the range of ±27°. After the top plate 3049 extends and fixes the swing frame 304, the propulsion beam 305 automatically controls the rock drill 3052 and the power head assembly 3054 to switch between construction with the top plate 3049 axis as the center. Please see Figure 5The propulsion beam 305 includes a rock drill propulsion cylinder 3051, a rock drill 3052 connected to the output end of the rock drill propulsion cylinder 3051, a power head propulsion cylinder 3053, a power head assembly 3054 connected to the output end of the power head propulsion cylinder 3053, an anchor bolt magazine assembly 3055 installed on one side of the power head assembly 3054, an anchor bolt gripper 3056 located between the power head assembly 3054 and the anchor bolt magazine assembly 3055, and an anchor bolt gripper 3056 located between the rock drill 3052 and the power head assembly 3054. The injection rack 3057 and the resin roll 3058 installed on the injection rack 3057 are equipped with two anchor bolt grippers 3056 on the push beam 305. These grippers are responsible for clamping the anchor bolts out of the anchor bolt magazine assembly 3055 and fixing them to the power head assembly 3054. After pushing them into the anchor bolt hole, they are released to complete the bolt replacement work. The anchor bolt magazine assembly 3055 can store up to 10 anchor bolts and is rotated by a motor for bolt replacement. During construction, after the top plate 3049 is fixed, the rock drill push cylinder 3051 first pushes the rock drill 3052 to drill holes (e.g., Figure 8 As shown in Figure a), after drilling is completed, the rod is retracted and switched to the anchor injection frame 3057 (as shown in Figure a). Figure 8 As shown in Figure b), a resin hose 3058 is installed on the anchor injection holder 3057 and connected to an air compressor to blow the anchor injection agent into the anchor bolt hole. Then, the connection is switched to the power head assembly 3054 (as shown in Figure b). Figure 8 As shown in c), after the anchor bolt gripper 3056 clamps out the anchor bolt and fixes it to the power head assembly 3054, the power head pushes it into the hole by the hydraulic cylinder 3053. The power head drives the anchor bolt to rotate and stir the anchoring agent until it solidifies. After solidification, the power head pulls out the anchor bolt to provide pre-tightening force. Then, the locking nut is rotated. Finally, the power head connects to the grouting machine 6 to grout and fix the anchor bolt to complete the anchor bolt support. Please see Figure 6 The suspended platform arm 4 includes a boom connecting seat 2 401, a telescopic boom 2 402 hinged to the boom connecting seat 2 401, a luffing cylinder 2 403 and a synchronizing cylinder 404 hinged between the boom connecting seat 2 401 and the telescopic boom 2 402, a suspended platform connecting seat 405 installed on the output end of the telescopic boom 2 402, a suspended platform 406 installed on the suspended platform connecting seat 405, and a pitch cylinder 407 hinged between the suspended platform connecting seat 405 and the suspended platform 406. The luffing cylinder 2 403 adjusts the pitch and swing range of the suspended platform arm 4 as a whole. Its pitch range is -30° to +60°, and its swing range is -45° to +45°. The suspended platform 406 is hinged to the telescopic boom 2 402 through the suspended platform connecting seat 405 and is equipped with a pitch cylinder 407. The pitch cylinder 407 is linked with the synchronizing cylinder 404 to keep the suspended platform 406 always horizontal. Please see Figure 7 , Figure 8 The center points of the rock drill 3052, the power head assembly 3054, and the anchor injection frame 3057 are set at the same center, and the three can swing within a range of ±27°.

[0023] The working arm and basket arm of this embodiment have a unique telescopic arm structure, a large working range, no jamming, no abnormal noise, a large adjustable angle for the swing frame, and the propulsion beam can be used for rod connection operations. The joint structure is stable, flexible, quick and accurate in positioning, simple to operate, and suitable for drilling and anchoring operations under multiple working conditions.

[0024] Second implementation method: Considering that in the first embodiment, the vibration during drilling will cause the propulsion beam to shift by a certain amount after the drilling is completed and the drill rod is withdrawn, it is obviously insufficient to rely solely on the top plate 3049 for positioning. Therefore, this embodiment adds a floating monitor 7 to monitor the shift based on the first embodiment, while the rest remains the same as the first embodiment. Please see Figure 9 The end of the working arm 3 is also fixedly connected to a floating monitor 7, and an air pump 8 is installed below the floating monitor 7. The air pump 8 is connected to the floating monitor 7 through an air supply pipe, and an air release pipe 9 is also connected to the air supply pipe. An air release valve is installed at the air outlet of the air release pipe 9. The air release valve is opened and closed by electromagnetic control (its structure is the same as that of a solenoid valve). Please see Figure 10 , Figure 11 and Figure 12The floating monitor 7 includes a fixed base 701, an inflatable base 702, and a floating base 703. The inner wall of the fixed base 701 has a ventilation cavity 7011 communicating with the interior of the inflatable base 702. Multiple horizontally symmetrically distributed connecting rods 704 are installed inside the inflatable base 702, and each end of a connecting rod 704 is fixedly connected to a hinge ball 705. Two hinge balls 705 are movably embedded in the inner walls of the fixed base 701 and the floating base 703, respectively. The inner wall of the fixed base 701 has an inlay groove matching the hinge ball 705, and a thin-film pressure sensor is installed on the inner wall of the inlay groove. 707 (the specific model is selected according to actual needs and will not be described in detail here), the side wall of the articulated ball 705 is fixedly connected to the contact head 706 that contacts the diaphragm pressure sensor 707. An alarm connected to the signal of the diaphragm pressure sensor 707 is also installed in the cab 2. Before drilling, the air pump 8 is started to inflate the floating monitor 7. After the air is filled, the air seat 702 expands, changing from a soft state before inflation to a state that can maintain its shape after inflation. This makes it easy to press the floating monitor 7 against the working surface. Then the push beam 30 5. Slide a short distance towards the working surface to allow the floating seat 703 to rest against the working surface, and then extend the top plate 3049 for fixation. Before drilling begins, open the vent valve on the vent pipe 9 to release the gas inside the floating monitor 7. At this time, the inflatable seat 702 becomes flaccid again, so the fixed seat 701 is in a floating state relative to the floating seat 703. Once the push beam 305 behind the fixed seat 701 shifts, it can be detected by the diaphragm pressure sensor 707. In this state, regardless of whether the floating seat 703 shifts relative to the fixed seat 701, Each pressure head 706 triggers a pressure point on the diaphragm pressure sensor 707. This pressure point is the starting point for offset monitoring. After drilling is completed and the rod is retracted, if the fixed seat 701 does not shift relative to the floating seat 703, the pressure point triggered by the pressure head 706 on the diaphragm pressure sensor 707 remains unchanged. If the fixed seat 701 shifts relative to the floating seat 703, the pressure point of the pressure head 706 on the diaphragm pressure sensor 707 also changes accordingly. Consequently, the diaphragm pressure sensor 707 triggers an alarm to promptly inform the operators. Please see Figure 11 The outer surface of the thin-film pressure sensor 707 is also fixedly connected with a protective pad 7071, and the protective pad 7071 is made of elastic and wear-resistant material (polyurethane elastic material is preferred, but other materials can also be selected according to actual needs). In order to prevent the pressure head 706 from directly contacting the thin-film pressure sensor 707 and causing wear, the protective pad 7071 is added to protect the thin-film pressure sensor 707. The inflatable seat 702 is made of flexible material (rubber is preferred, but other materials can be selected according to actual needs), while the connecting rod 704 and the articulated ball 705 are made of high-strength rigid material (alloy material is preferred, but other materials can be selected according to actual needs). In order to keep the deflated floating seat 703 in a floating state, the inflatable seat 702 must be made of flexible material. However, since the floating monitor 7 needs to be pressed against the working surface, the connecting rod 704 and the articulated ball 705 are made of rigid material to prevent deformation. Please see Figure 11 The side wall of the floating seat 703 is also fixedly connected with multiple evenly distributed positioning cones 708. The positioning cone 708 includes a corrugated telescopic cylinder 7081 and a cone head 7082. The corrugated telescopic cylinder 7081 is made of a highly elastic material, and the cone head 7082 is made of an alloy material. The rock surface of the working face is uneven. In order to enhance the fixing effect of the floating seat 703, the positioning cones 708 are added to improve the positioning effect and prevent side slippage from affecting the accuracy of the monitoring results. Please see Figure 12 The corrugated telescopic cylinder 7081 has a hollow structure. The inner wall of the floating seat 703 has a second ventilation chamber 7031 that communicates with the corrugated telescopic cylinder 7081. A solenoid valve 7032 is installed at the air inlet of the second ventilation chamber 7031 (the specific model is selected according to actual needs and will not be described in detail here). Since the rock surface is of varying depths, in order to improve the firm grip of all positioning cones 708, the telescopic performance of the corrugated telescopic cylinder 7081 is used to allow the positioning cones 708 to adapt to the shape of the rock surface. When inflating, the solenoid valve 7032 is opened to allow gas to be filled into the corrugated telescopic cylinder 7081, thereby further effectively preventing the floating seat 703 from sliding sideways. Please see Figure 13 The cab 2 is also equipped with an adjustment indicator connected to the diaphragm pressure sensor 707. The adjustment indicator includes a circular graphic display 10, and the center point of the graphic display 10 corresponds to the starting point of the pressure head 706. The graphic display 10 displays the position by connecting the center point of the starting point and the offset point. The alarm can only play the role of offset alarm, but how to adjust the offset swing frame 304 back to its original position is still adjusted manually by visual inspection. This seriously affects the construction progress. Therefore, by adding a graphic display 10, when the diaphragm pressure sensor 707 detects the offset, the diaphragm pressure sensor 707 records the starting point and the offset point. Then, the diaphragm pressure sensor 707 sends the coordinate information of the starting point and the offset point and the offset angle to the graphic display 10. The graphic display 10 displays the starting point at its center point and the offset point at other positions. The center point of the starting point and the offset point are connected by a straight line. The operator can use the straight line to operate the working arm 3 to reset the swing frame 304. This embodiment adds an offset monitoring device to the top plate 3049 to monitor the offset of the propulsion beam before and after drilling. This allows operators to be aware of the offset in a timely manner. Compared with the existing technology that only detects the offset after the rod hits the target, this method can detect the offset in advance and take proactive measures to ensure the smooth implementation of subsequent grouting and anchor bolt installation. In addition, the offset direction and amount can be presented to the operators in a visual form, which is convenient for adjustment. Compared with the existing technology of manual visual adjustment, this method can effectively improve efficiency and safety.
