Description

Technical Field

[0001] The present application relates to the field of road engineering slope protection equipment, and in particular to an integrated drilling, anchoring and grouting equipment for road engineering construction. Background Art

[0002] Slope refers to the slope part extending outward from the edge of the roadbed on the cross section of the road, and sometimes also refers to the slopes on both sides of the road. In road construction, slope construction is an important component, and its design and construction are very important for the stability and safety of the road, especially in mountainous road construction. The importance of slopes is particularly significant. The geological conditions in mountainous areas are complex, and slopes are easily affected by natural disasters such as landslides and mud-rock flows. Through reasonable slope design and reinforcement, the stability of the slope can be significantly improved.

[0003] The slope reinforcement process is relatively complicated. First, a scaffolding is built. After the technicians calculate the drilling angle, they use a drill rod to drill the hole, pull out the drill rod and clean the hole, and then inject grout. After the concrete slurry solidifies, subsequent slope surface reinforcement measures are taken to prevent surface collapse.

[0004] Nowadays, slope reinforcement technology has become more mature and a fixed reinforcement process system has been formed. However, the functions of the devices used in the slope reinforcement process are still relatively simple. For example, the drilling process uses drilling equipment, the grouting process uses grouting pumps and grouting pipes, and the anchoring process is usually done manually to manually send the anchor rod into the borehole.

[0005] Therefore, based on the above slope reinforcement process, if a multifunctional integrated equipment is designed and applied to the above drilling, anchoring and grouting processes, it can save the time of staff in replacing and debugging equipment and improve the efficiency of the slope reinforcement process. Summary of the invention

[0006] In order to improve the efficiency of the slope reinforcement process and reasonably shorten the road construction period, the present application provides an integrated drilling, anchoring and grouting equipment for road engineering construction.

[0007] The present application provides an integrated drilling, anchoring and grouting equipment for road engineering construction, which adopts the following technical solution: An integrated drilling, anchoring and grouting device for road engineering construction comprises a base, an equipment compartment is arranged on the base, and further comprises: An arm is arranged above the base, and its bottom wall is connected to the base. An anchor rod bin is provided in the arm, and the anchor rod bin is used to place anchor rods. One end wall of the anchor rod bin is open; A support assembly is disposed between the arm and the base, connects the arm and the base, and adjusts the tilt angle of the arm; A driving motor is slidably connected to the top of the arm, and a connecting piece for connecting an anchor rod and a drill rod is provided at the end of its output shaft; A cleaning assembly, arranged at the bottom of the arm, for cleaning the debris in the drill hole; The grouting assembly is arranged on the base and is used for injecting grout into the drill hole.

[0008] By adopting the above technical solution, the base is the supporting structure of the equipment components in the above technical solution, and the equipment bin is arranged on one side of the base for installing and protecting the components arranged inside the base; the arm is the main component for drilling, anchoring and grouting, and the anchor bin opened inside the arm is used to place the anchors in the anchoring process, and one end of the anchor bin is open, and the construction personnel can place the anchors in the anchor bin according to the open end of the anchors to replenish the anchors in the anchor bin; The push motor is connected to the arm rod by sliding along the length direction of the arm rod, sliding from one end of the arm rod to the other end, and the piston rod end of the push motor is connected to the anchor rod or drill rod through the connecting piece. During the drilling process, the push motor is pushed forward, and the output shaft of the push motor rotates, and the drill rod rotates and feeds to drill holes on the slope. After the drilling is completed, the push motor is retracted, and the drill rod is pulled out of the borehole. Then, the dust in the borehole is cleaned by the cleaning component, and the anchor rod in the anchor rod bin is installed on the connecting piece. The push motor is fed again to deliver the anchor rod to the borehole, and finally grouting is performed by the grouting component. To complete the above process, the construction personnel need to calculate the injection inclination angle of the anchor rod in advance, and adjust the inclination angle of the arm with the help of the support assembly according to the calculation result, so that the arm meets the injection inclination angle. The change of the inclination angle of the arm needs to be achieved by the support assembly. The support assembly connects the base and the arm, and adjusts the inclination angle of the arm under the stable support of the base.

[0009] Optionally, also include: A plurality of rack rods are arranged on two opposite side walls of the arm rod, and the plurality of rack rods are distributed along the length direction of the arm rod; The screw groove is fixedly connected to the bottom end of the frame rod, and the inner thread is connected with a screw, and the top end of the driving motor is threadedly connected to the screw.

[0010] By adopting the above technical solution, the sliding drive of the push motor along the arm is realized. If the sliding drive of the push motor is arranged in the anchor rod bin inside the arm rod, it will affect the installation and placement of the anchor rod bin. Therefore, the sliding drive of the push motor is moved out of the anchor rod bin and placed above the anchor rod bin, and supported by multiple racks. The frame rod supports the groove wall of the screw groove. The above-mentioned sliding drive component is a screw that is rotatably connected in the screw groove. The top of the pushing motor is threadedly connected to the screw. The pushing motor slides along the screw groove through the rotation of the screw. A slider that adapts to the screw groove can also be threadedly connected to the screw. The sliding drive of the pushing motor is realized by fixing the slider to the pushing motor.

[0011] Optionally, also include: A lifting frame is vertically slidably connected to the anchor rod compartment, and the lifting frame is arranged in layers, respectively used to place the anchor rod and the drill rod; A lifting power member is arranged on the bottom wall of the anchor bar bin and is used for lifting the lifting frame.

[0012] By adopting the above technical solution, the lifting frame and the lifting power part are both used to provide auxiliary installation of the anchor rod in the anchor rod bin. During the preparation work, the construction personnel place the pre-made anchor rod in the anchor rod bin through the open end of the anchor rod bin, and then adjust the angle and position of the arm rod, and the construction personnel install the anchor rod on the output shaft of the pushing motor, and push the anchor rod in the anchor rod bin into the drilled hole through the pushing motor; in the process of docking the anchor rod in the above anchor rod bin and the pushing motor, the lifting power part first lifts the lifting frame until one end of the anchor rod is aligned with the output shaft of the pushing motor, and the two are flush in height, and then the relevant personnel push the anchor rod to dock and install one end of it with the connecting piece on the output shaft of the pushing motor; In addition, in the above scheme, for the anchor rod that is aligned with the output shaft of the driving motor, a power piece can be added to the lifting frame to replace the manual pushing of the anchor rod by the construction personnel; In the above scheme, the lifting frame is arranged in layers, and the space in the anchor rod bin is divided into multiple layers, and each layer is used to pack different types of rod bodies. Since the implementation environment of this scheme is limited to slope reinforcement, usually only anchor rods and drill rods are required. Therefore, the lifting frame can be divided into two layers, one of which is used to place drill rods and the other is used to place anchor rods. Generally speaking, drill rods are placed on the upper layer of the lifting frame and anchor rods are placed on the lower layer of the lifting frame. Before the lifting power unit is operated, the lower anchor rods and the upper drill rods are stored in the anchor rod groove. The opening end of the anchor rod bin is opened corresponding to the lower layer of the frame rod, that is, before the lifting power unit is operated, the construction personnel can directly push the anchor rods into the lower lifting frame.

[0013] Optionally, the support assembly includes: A support seat is arranged above the base, and a support cylinder is hinged on the support seat; A support block is arranged at the bottom end of the arm rod. A pushing member is fixedly connected inside the support block to push the arm rod to rise and fall. The piston rod end of the support cylinder is hinged to the outer bottom wall of the support block.

[0014] By adopting the above technical solution, the support seat and the support block are used to change the inclination angle of the arm, which is achieved by the support cylinder arranged on the support seat. The support cylinder is arranged to be tilted, and the bottom end of the cylinder body is hinged, so that the inclination angle of the support cylinder body itself can be changed. The piston rod end of the support cylinder is hinged to the bottom end of the support block, and the inclination angle of the support block and the arm is controlled by controlling the extension length of the support cylinder. During the change of the arm angle, the two ends of the support cylinder are hinged so that it can rotate flexibly. A pusher is arranged in the support block, which makes the arm rise and fall on the basis of a fixed inclination angle when the inclination angle of the arm is changed, and changes the height of the arm so that different parts of the arm are aligned with different height parts of the slope.

[0015] Optionally, the cleaning component includes: An air chamber is provided at the bottom end of the arm and below the anchor chamber, and an air nozzle is provided at a portion of one end of the arm corresponding to the air chamber, and the air nozzle is connected to the air chamber; A gas rod is arranged in the gas bin, with its length direction parallel to the length direction of the gas bin, the inside of the gas rod is hollowed out, and one end of the gas rod is provided with a gas port connected to the inside of the gas rod; A sealing plate is formed at one end of the gas rod away from the gas nozzle, the size of the sealing plate is the same as the size of the gas chamber, and a portion of the sealing plate corresponding to the gas rod is pierced with a through hole connected to the inside of the gas rod; The air pump is arranged in the equipment bin and is connected to the air bin through an air pipe.

[0016] By adopting the above technical solution, the cleaning component is used to clean the dust in the hole after drilling a hole on the slope soil. The above solution uses high-pressure airflow to blow out the dust in the hole. Therefore, it is necessary to send one end of the air outlet of the cleaning component into the bottom of the hole, and the airflow mixed with dust from the bottom of the hole is blown out from the hole of the hole. The key point of the technical solution is to send the air outlet part into the bottom of the hole. It is realized through an air bin, an air rod, and an air pump. The air pump is arranged in the equipment bin on the base, and mainly plays the role of conveying airflow to the air bin through the air pipe. In the above scheme, it is used as an air source. The air bin is opened at the bottom of the arm, that is, the part below the anchor bin. The air bin and the anchor bin are not connected and are independent. Both ends of the air bin extend to both ends of the arm. The air pipe connected to the air pump is plugged into one end of the air bin, and airflow is sent into the air bin from one end of the air bin. The airflow inside the air bin can also be sucked out from the end of the air bin to increase or decrease the air pressure in the air bin. An air rod is arranged in the air bin. The air rod is a hollowed-out tube, one end of which is an air outlet. The air outlet of the air rod is arranged at the end of the air rod away from the air inlet end of the air bin. A vertically arranged sealing plate is formed at the end of the air rod away from its own air outlet, that is, the end of the air rod close to the air inlet of the air bin. The size of the sealing plate is the same as that of the air bin. The edges of the sealing plate on multiple sides are fitted with the inner wall of the corresponding side of the air bin. A perforation is arranged on the sealing plate corresponding to the air rod. Therefore, in the process of the air pipe continuously supplying air to the air bin, the air pressure on one side of the sealing plate inside the air bin gradually increases, pushing the air rod to move along the air bin to one end of the air nozzle, until the air rod extends out of the air nozzle and extends into the bottom of the drilled hole. In practical applications, sealing lips may be provided between the sealing plate and the inner walls of the gas chamber, and rubber seals in the prior art may be sufficient.

[0017] Optionally, also include: The sealing valve is arranged on the sealing plate and corresponds to the perforation of the sealing plate, and is used to block or open the perforation.

[0018] By adopting the above technical solution, the sealing valve is used to conduct or close the perforation on the above sealing plate. When the air pipe injects air into the air bin, the sealing valve closes the perforation, so that the air bin and the inside of the air rod are not connected. The air pressure on the air inlet side of the sealing plate gradually increases, pushing the air rod to slide. After the air outlet of the air rod extends into the bottom of the drilled hole, the sealing valve opens to blow the air out from the air outlet of the air rod. In the above process, it is necessary to reasonably control the airflow delivery speed in the gas chamber. During the sliding stage of the gas rod, the sealing valve is closed. If the airflow delivery speed is too fast at this time, the pressure in the gas chamber will increase suddenly, causing the gas rod to protrude instantly and be inserted into the drill hole, which may easily damage the hole wall of the drill hole. Therefore, during the sealing valve closing stage, the airflow velocity should be maintained in the preset speed range. When the sealing valve is opened, the airflow velocity is enhanced to blow out the dust in the drill hole.

[0019] It is recommended that the sealing valve in the above scheme be implemented by an electrically controllable solenoid valve.

[0020] Optionally, the grouting assembly comprises: A grouting bin, arranged in the equipment bin and used for containing concrete slurry; A grouting pump is arranged in the equipment compartment, and a grouting pipe is connected to a grouting outlet of the grouting pump; A winding device is arranged at the bottom of one end of the arm and is used for winding the grouting pipe.

[0021] By adopting the above technical solution, the grouting bin and the grouting pump are used for the grouting process after drilling and cleaning. The grouting bin is filled with concrete slurry. The grouting pump provides the conveying power of the concrete slurry, and outputs the concrete slurry from the grouting bin through the grouting pipe. One end of the grouting pipe is connected to the grouting bin, and the other end is wound on the winding device. During grouting, the construction personnel can remove the grouting pipe from the winding device. The winding device can be a cylindrical structure with a hollow interior, which rotates around an axis. One end of the winding device is connected to the grouting bin through a section of grouting pipe, and the other end is connected to another section of grouting pipe. Therefore, construction personnel only need to rotate the winding device to tighten and lower the grouting pipe without manual winding.

[0022] Optionally, the connecting piece includes: The connecting rod is arranged horizontally and has a threaded hole at one end; The clamping disk is fixedly connected to one end of the connecting rod close to the threaded hole, the surface of the clamping disk protrudes from the end surface of the connecting rod, and the clamping disk is composed of multiple independent parts, and the multiple independent parts slide radially.

[0023] By adopting the above technical solution, the connector provides two connection methods at the same time, namely, the threaded connection at one end of the connecting rod and the clamping of the clamping disk, wherein the threaded connection at the end of the connecting rod is used to fix the drill rod. Due to the need for drilling holes with the drill rod, if the clamping disk is used to fix the drill rod, when the drill rod rotates to drill holes, the part connected between the clamping disk and the drill rod is prone to relative rotation and friction, which damages the clamping disk and reduces the drilling effect of the slope. Therefore, a threaded connection method that is easy to disassemble and assemble is selected, a threaded hole is opened at one end of the connecting rod, and a thread that is adapted to the threaded hole is opened at the end of the drill rod, so that one end of the drill rod is threadedly connected to the connecting rod; In this technical solution, the clamping disc is used to clamp the anchor rod. In actual road engineering, the anchor rod is usually composed of multiple steel bars, and its diameter depends on the diameter and number of the steel bars. The various parts of the clamping disc slide radially to clamp the anchor rods of different diameters. The clamping disc can use a three-jaw chuck.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. This application integrates the three core functions of drilling, anchoring and grouting into a single device through an integrated design, which significantly simplifies the complex process of traditional slope reinforcement, reduces equipment procurement and maintenance costs, and improves operating efficiency; 2. By setting up multifunctional connectors, the drill rod and anchor rod can be quickly switched, which reduces the equipment replacement time, ensures the continuity of construction, and further improves the efficiency of slope reinforcement operations; 3. The application has a reasonable structural design and is easy to operate. It is particularly suitable for areas with harsh natural environments and complex working conditions such as mountainous areas, effectively reducing safety hazards and improving construction safety.

Therefore, after the above-mentioned inclination angle of the arm 3 is fixed, the cylinder drives the arm 3 to rise and fall while maintaining the angle, changing the height of the arm 3, and improving the flexibility of the arm 3.

[0038] Reference Figure 1 and Figure 3 An anchor rod bin 31 is provided inside the arm 3 for holding anchor rods and drill rods used in the anchoring process. The arm 3 is hollowed out inside and the top wall is opened, so that the arm 3 is in a shell shape as a whole. A plurality of rack rods 32 are fixedly connected to the opposite side walls of the arm 3. The rack rods 32 on the opposite side walls are symmetrically distributed. A screw groove is fixedly connected to the top of the plurality of rack rods 32. The length direction of the screw groove is parallel to the length direction of the arm 3. The screw groove is supported by the rack rod 32 and is arranged above the arm 3 in parallel with the arm 3. The screw groove and the rack rod 32 are in a door shape, so that the part between the screw groove and the rack rod 32 is separated by a preset distance. A screw is rotatably connected in the screw groove, and the length direction of the screw is parallel to the length direction of the screw groove.

[0041] Reference Figure 3 and Figure 5An air bin 38 is provided at the bottom of the arm 3 and below the anchor bin 31. The air bin 38 is independent of the anchor bin 31 and is not connected. A perforation is provided at one end of the arm 3 corresponding to the air bin 38 to connect the air bin 38 with the outside world, and an air nozzle 381 is formed at the part of the arm 3 corresponding to the perforation; an air rod 382 is provided in the air bin 38, and the length direction of the air rod 382 is parallel to the length direction of the air bin 38. The end of the air rod 382 close to the air nozzle 381 has a smaller diameter and is a tip. The inside of the air rod 382 is hollowed out so that the air rod 382 is tubular as a whole. The tip of the air rod 382 is provided with an air port connected to the inside of the air rod 382, ​​and the end of the air rod 382 away from the air nozzle 381 is fixedly connected or integrally formed with a sealing plate 383, and the sealing plate 383 is arranged perpendicular to the bottom wall of the air bin 38, and its four side edges are pressed against the air bin 3 8 side walls, the side edges of the sealing plate 383 are sealed with the inner walls of the air bin 38 on each side, so that the air bin 38 spaces on both sides of the sealing plate 383 are blocked, and the sealing plate 383 is provided with a perforation connected to the inside of the air pipe, and the sealing plate 383 is provided with a sealing valve 384 corresponding to the perforation. In this embodiment, the sealing valve 384 adopts an electromagnetic valve, and the construction personnel can control the opening and closing of the electromagnetic valve by electric control, thereby controlling the conduction between the air bin 38 space on one side of the sealing plate 383 and the internal space of the air rod 382; the end of the arm 3 away from the air nozzle 381 is connected to the part of the air bin 38 corresponding to the air bin 38 with an air pipe, one end of the air pipe is plugged into the arm 3 and connected to the air bin 38, and the other end is plugged into the equipment bin 11, and a fan connected to the air pipe is provided in the equipment bin 11, and the air outlet of the fan supplies air to the air bin 38 through the air pipe.

[0042] Therefore, after the drilling is completed, the construction personnel align the air nozzle 381 with the drill hole in advance, and then the fan supplies air to the inside of the air bin 38, and the sealing valve 384 is closed, so that the air bin 38 space near the air pipe side of the sealing plate 383 is sealed. As the air pipe continues to input air, the air pressure in the air bin 38 increases, pushing the air rod 382 to slide to the side of the air nozzle 381, and protruding from the air nozzle 381, until the air rod 382 is transported to the inside of the drill hole. After one end of the air port of the air rod 382 extends to the bottom of the air hole, the sealing valve 384 is opened, and the air flow enters the inside of the air pipe and is output from the air port, and then the air flow is blown out from the bottom of the drill hole at high speed.

[0043] Replay Figure 1In this embodiment, the chamber inside the equipment bin 11 for holding concrete is a grouting bin. A grouting pump is also provided in the equipment bin 11. The grouting pump is connected to the grouting bin through a pipeline to extract the concrete slurry in the grouting bin; a grouting pipe 4 is provided on the base 1. One end of the grouting pipe 4 is fixed to the bin wall of the equipment bin 11 and extends into the equipment bin 11, connected to the slurry outlet of the grouting pump, and conveys the concrete slurry extracted from the grouting bin by the grouting pump. Since the grouting pipe 4 needs to extend into the bottom of the borehole during the grouting process, the length of the grouting pipe 4 needs to meet the requirements. In this embodiment, a horizontally arranged winding roller 41 is rotatably connected to one end of the arm 3 for winding the grouting pipe 4; when performing the grouting process, the construction personnel rotate the winding roller 41, remove the grouting pipe 4 and insert it into the borehole.

[0044] The implementation principle of the integrated drilling, anchoring and grouting equipment for road engineering construction in an embodiment of the present application is as follows: construction personnel operate the integrated drilling, anchoring and grouting equipment to bring it close to the slope that needs to be reinforced, and operate the structures and devices provided on the equipment to perform the drilling, anchoring and grouting processes in sequence according to the data results pre-calculated by the technicians.

[0045] First, according to the angle calculated in advance by the technicians, the construction personnel operate the support cylinder 21 to make the arm 3 have a preset tilt angle. The tilt angle of the arm 3 determines the drilling angle of the slope and the angle of the anchor rod. The construction personnel transport the anchor rod from the open end of the arm 3 to the anchor rod bin 31.

[0046] The lifting cylinder 37 operates to lift the lifting frame 36, so that the drill rod on the upper layer of the lifting frame 36 is aligned with the connecting rod 34 on the push motor 33, and the construction personnel tighten the drill rod to fix it. The screw rotates to drive the push motor 33 to slide along the arm 3, and the push motor 33 rotates while sliding, driving the drill rod to drill a hole. When the drill rod completes the drilling process, the push motor 33 is withdrawn, and the construction personnel remove the drill rod, and the drilling process is completed.

[0047] The piston rod of the lifting cylinder 37 continues to extend, so that the anchor rod on the lower layer of the lifting frame 36 is aligned with the connecting rod 34, and the anchor rod is clamped by the clamping plate 35, pushing the motor 33 to slide, driving the anchor rod to move downward and be inserted into the drill hole.

[0048] Then the construction personnel take down the grouting pipe 4 from the winding roller 41 and insert the grouting pipe 4 into the drill hole to complete the grouting process.

[0049] Finally, the construction workers replenished the anchor rods immediately.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
