Description

Technical Field

[0001] The present invention relates to the technical field of anchor agent installation, and in particular to a resin anchor agent spraying device and a tunnel construction equipment. Background Art

[0002] As a key part of the tunnel construction of the New Austrian Tunneling Method, low-prestress anchor bolts play an important role in preventing disasters such as rock bursts and large deformations, and are widely used. After the tunnel is excavated, the prestressed anchor bolts are immediately installed and prestressed, so as to form a load-bearing arch with a certain thickness in the surrounding rock, adjust the stress distribution inside the surrounding rock, and actively reduce the surrounding rock pressure on the excavation surface, thereby reducing and eliminating the occurrence of rock bursts and preventing the occurrence of large deformations. The low-prestress resin hollow anchor bolt has the advantages of being less affected by the surrounding rock, having a fast response speed, and applying a large prestress compared with the low-prestress expandable shell hollow anchor bolt, and is widely used in mines, tunnels and other fields.

[0003] At present, the construction of resin anchor agents mainly relies on manual pushing, with a low degree of mechanization and a mismatch with mechanization. Especially for plateau railway tunnels, the characteristics of uneven hardness of the surrounding rock, large demand for tunnel support, and combination of long and short anchor bolts make the demand for mechanized construction of resin anchor agents more prominent.

[0004] In recent years, with the continuous improvement of the degree of mechanization, some improvements and relatively novel tooling have emerged in the blowing of resin anchor agents.

[0005] For example, the Chinese invention patent application with the publication date of February 22, 2017 and the publication number of CN 106437797 A discloses an automatic spraying and loading device for resin anchor agents, which solves the problems of poor working environment, high dust and high gas, low safety factor, high labor intensity and low production efficiency for the anchor drilling workers in coal mines. The device includes a main frame, a loading door, a connecting and guiding spray pipe, a conveying chain system and a driving motor. The main frame is provided with four frame box plates on the top, bottom, left and right. The frame box plates of the main frame are provided with loading windows and conduit ports. A loading door is provided on the loading window, and a connecting and guiding spray pipe is provided on the conduit port. A conveying chain system is arranged inside the main frame. The conveying chain system is driven by a driving motor, and a number of conduits that can be docked with the connecting and guiding spray pipe are fixed on the conveying chain system.

[0006] As for the Chinese invention patent application with the publication date of March 12, 2021 and the publication number of CN 112483148 A, it discloses an automatic spraying and loading device for resin anchor agents, including an operation gantry and a spraying box. The operation gantry is fixedly installed on the upper surface of the foundation pit through a positioning disc. The spraying box includes a box body, a turntable and six groups of resin anchor agent clamping components. The turntable is rotatably installed in the operation gantry. The box body is fixedly installed on the upper surface of the turntable. The resin anchor agent clamping components are fixedly installed in the box body. The turntable is annularly and equidistantly arrayed with first guide pipes. The bottom of the turntable is drivingly connected with a driving component. A second guide pipe is fixedly installed at the central position in the operation gantry. The vertical center lines of the resin anchor agent clamping components and the first guide pipes are collinear. An air pump is slidably installed on the lower surface of the operation gantry through a first electric slide table. The air pump is fixedly communicated with the box body and also fixedly communicated with the resin anchor agent clamping components.

[0007] In the actual application process of the technical solution of the above-mentioned invention patent application, especially during the pushing and installation of resin anchor agents, there are certain limitations. It is impossible to install two different resin anchor agents at the same time, and there are problems such as poor reliability and inability to guarantee the construction quality. Therefore, it is necessary to design a device and method to test the influence between the characteristics of concrete and frozen soil, and find the optimal working temperature of concrete on the premise of not affecting the stability of frozen soil.

[0055] As a preferred embodiment, as Figure 8 shown, the wheel type pipe feeder 4.2 includes a first clamping wheel 4.2.2 and a second clamping wheel 4.2.3 that clamp the hard pipe 4.4. The first clamping wheel 4.2.2 and the second clamping wheel 4.2.3 are driven by a chain drive mechanism.

[0056] As a preferred embodiment, the idler rollers 4.5 are arranged at intervals on the frame. A drill rod holder 4.3 is provided on the frame. The hard pipe 4.4 passes through the wheel type pipe feeder 4.2, the drill rod holder 4.3, and the idler rollers 4.5 in sequence. The wheel type pipe feeder 4.2 and the drill rod holder 4.3 are connected to the frame through a lifting seat 4.7.

[0057] As the best embodiment, the present invention includes a storage hopper and a pushing hopper: An anchoring agent push plate, a sliding plate, a cam, a swing motor, a transmission shaft, a feeder, etc. are installed on the storage hopper for storing resin anchoring agents and sorting the resin anchoring agents. A cylinder, a piston, a connecting block, etc. are installed on the pushing hopper for pushing the resin anchoring agents into the pipeline, and then with the help of externally connected compressed air, the resin anchoring agents are blown into the bolt hole along the pipeline through the pipe feeding mechanism. The storage hopper is composed of a bin, a push plate, a sliding plate, a cam, a camshaft, a feeder, a swing motor, and a transmission shaft. The pushing hopper is composed of a pushing bin, a cylinder, a piston rod, a piston cylinder, and a connecting block. The pipe feeding mechanism is composed of idler rollers, steel pipes, drill rod holders, and wheel type pipe feeding mechanisms.

[0058] As described above, the motor drives the sorting mechanism and the push plate through chain drive to sort the resin anchor agents, and then sends the resin anchor agents into the cylinder in the pushing hopper. The air cylinder on the pushing hopper drives the piston rod to push the resin anchor agents into the pipeline, and the resin anchor agents are blown to the bottom of the hole through the pipe feeding mechanism by connecting to compressed air through the connecting block.

[0059] Specifically, the present invention includes a storage bin, a mechanical pushing mechanism, a pneumatic mechanism, a cleaning mechanism, and a rigid pipe conveying mechanism. The storage bin is used for storing and sorting the anchor agents and conveying the anchor agents to the pushing mechanism. The pushing mechanism pushes the anchor agents to the pneumatic mechanism. The pneumatic mechanism blows the anchor agents to the rigid pipe conveying mechanism. The rigid pipe conveying mechanism conveys the anchor agents into the anchor hole, and the cleaning mechanism is used for cleaning the anchor agent conveying channel.

[0060] The present invention is mainly composed of a storage mechanism 1, a feeding mechanism, a pipeline 3, and a pipe feeding mechanism 4.

[0061] The storage mechanism 1 is used for storing and sorting the anchor agents. Among them, the storage bin 1.1 is used for storing materials and installing other components. The partition plate 1.2 is used to divide the storage bin 1.1 into two parts for storing anchor agents with different reaction rates. The push plate 1.3 is installed on the storage bin 1.1. The push plate 1.3 and the bin 1.1 form a V-shaped blanking port, and the resin anchor agents can fall one by one through the V-shaped blanking port.

[0062] In order to prevent multiple anchor agents from falling down simultaneously and getting stuck at the V-shaped blanking port, a cam 1.10 is arranged below the push plate 1.3. The cam 1.10 is driven by a 180° cycloidal motor 1.7, a chain 1.6, and a cam transmission shaft 1.4, and then pushes the push plate 1.3 to make a slight movement to prevent the anchor agents from getting stuck at the V-shaped blanking port.

[0063] In order to adapt to anchor agents with different diameters, a sliding plate 1.5 is arranged on the push plate 1.3. The passing diameter of the V-shaped blanking port is changed by adjusting the sliding plate 1.5, so as to realize the construction of anchor agents with different diameters. In order to match the V-shaped blanking port, a baffle 1.12 is arranged at the outlet of the storage bin 1.1 to adjust the gap of the outlet and prevent multiple anchor agents from falling simultaneously.

[0064] In order to send the anchor agents into the pushing device one by one, a disc grooved resin anchor agent feeder 1.9 is arranged below the outlet of the storage bin 1.1. The feeder 1.9 is driven by a 180° cycloidal motor 1.7 and a transmission shaft 1.8, and rotates 180° each time to send the anchor agents into the pushing device. In order to detect in time that the resin anchor agents are stuck, a proximity sensor 1.11 is arranged at the V-shaped blanking port. Once the material is monitored, the alarm device will be triggered in time to give an alarm.

[0065] The feeding mechanism 2 is used to push the anchor agents sorted by the storage mechanism 1 into the pipeline. Among them, the receiving bin 2.1 is used to receive the anchor agents sent by the storage mechanism and fix other components. The inside of the receiving bin is in a V-shaped structure for guiding the resin anchor agents, so that the anchor agents sent by the disc-grooved resin anchor agent feeder 1.9 can enter the inside of the cylinder 2.3 with grooves. The piston rod 2.2 drives the anchor agents into the air path connection block 2.5 under the drive of the air cylinder 2.4. The air path connection block 2.5 is used to connect the blowing pipeline, the water pipeline and the air path to make them communicate with each other.

[0066] The air path connection block 2.5 is used to connect each pipeline. After the resin blown anchor agents are pushed to the resin blowing pipeline 3.1 by the pushing device, the compressed air enters the resin blowing pipeline 3.1 through the compressed air pipe 3.2 and the air path electromagnetic control valve 3.3. The resin anchor agents reach the bottom of the hole along the resin blowing pipeline 3.1 through the pipe feeding mechanism. If the resin anchor agents break inside the resin blowing pipeline 3.1 during the construction process, high-pressure water is needed to clean the pipeline. The high-pressure water enters the resin blowing pipeline 3.1 through the high-pressure water pipe 3.4 and the water path electromagnetic control valve 3.5 to clean the pipeline. In addition, after the construction is completed, the pipeline may need to be cleaned to facilitate the next use.

[0067] The pipe feeding mechanism 4 is used to send the hard pipe to the bottom of the bolt hole. The resin anchor agents reach the bottom of the hole along the hard pipe to complete the final blowing of the resin anchor agents. The hard pipe 4.1 is connected to the hard pipe connecting pipe 4.4 by threads and enters the wheel-type pipe feeder 4.2 through the idler roller 4.5 and the drill rod holder 4.3. The wheel-type pipe feeder 4.2 provides power. The first clamping wheel 4.2.2 and the second clamping wheel 4.2.3 are driven by the motor 4.2.1 through the chain 4.2.5 and the tensioning wheel 4.2.4, and the hard pipe is conveyed by generating friction force by clamping the hard pipe. The pipe feeding mechanism 4 adopts a clamping wheel design, which can push hard pipes with different diameters through, so as to realize the blowing of resin anchor agents with different diameters. When hard pipes with different diameters need to be conveyed, only the distance between the first clamping wheel 4.2.2 and the second clamping wheel 4.2.3 and the tensioning wheel 4.2.4 need to be adjusted.

[0068] The drill rod holder 4.3 plays a guiding role, the idler roller 4.5 provides auxiliary support for the hard pipe 4.1, and the lifting oil cylinder 4.7 is used to adjust the height of the hard pipe to facilitate hole alignment. The installation beam 4.6 is used to install components such as idler rollers, drill rod holders and wheel-type pipe feeders. The whole device can be integrally installed on the tunnel construction equipment for resin anchor agent construction.

[0069] The above actions are controlled by motors, air cylinders and compressed air. The on-off of the oil path or air path can be controlled by the corresponding solenoid valves to achieve automatic control. Each action can be controlled singly, or can be continuously controlled through the controller to achieve one-key installation of resin.

[0070] In the present invention, the connection method can be replaced by threads, keys, gears, fasteners, or mating forms.

[0071] In the present invention, the bearings described can be replaced by self-lubricating bearings, copper bushings, or other bushings.

[0072] In the present invention, the driving motor described can be replaced by driving methods such as motors, oil cylinders, etc.

[0073] A tunnel construction device includes a robotic arm, and the feeding mechanism is arranged on the robotic arm. That is, the feeding mechanism can be installed on any tunnel construction device with a robotic arm, such as a rock bolt jumbo, etc.
