Description

Technical Field

[0001] The invention belongs to the field of anchor bolt anchoring, in particular to an umbrella-shaped electric anchor bolt. Background Art

[0002] Slope reinforcement is an important part of geotechnical engineering, especially in the fields of highway, railway, water conservancy, mining and other engineering. With the continuous advancement of engineering construction, the stability of slopes has become increasingly prominent. Slope instability will not only cause huge economic losses, but also threaten people's lives and property. Therefore, it is extremely important to take effective slope reinforcement measures to ensure the stability and safety of the slope. Anchor reinforcement technology is a reinforcement method that forms a composite body between anchors and rock and soil, thereby enhancing the bearing capacity of rock and soil.

[0003] However, after being driven into the soil, traditional anchor rods are easily affected by various factors such as time, rainfall and earthquakes, causing loosening and relaxation, which in turn leads to the gradual weakening of the anchoring effect between the anchor rod and the soil, which may cause safety hazards. In addition, existing anchor rods in hard soil layers often face the problem of untimely opening of the external expansion rod or insufficient expansion, which further affects the self-expansion effect and overall stability of the anchor rod. Summary of the invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide an umbrella-shaped electric anchor rod which is simple to operate, saves time and effort, and has a high safety factor.

[0005] Technical solution: An umbrella-shaped electric anchor rod of the present invention comprises an anchor rod body, a rotating motor, an electric push rod assembly, an expansion assembly, an anchor head, a mud bin, a spiral push rod and a mud channel, wherein the mud bin is arranged inside the anchor rod body, the anchor head is arranged at the front end of the anchor rod body, the mud channel is arranged outside the anchor head, the rotating motor is arranged inside the rear end of the anchor rod body and is connected to the spiral push rod, the electric push rod assembly and the expansion assembly are both arranged on the outside of the anchor rod body, and the electric push rod assembly is connected to the expansion assembly; the electric push rod assembly comprises a protection bin, a first push rod, a second push rod, a third push rod and a clamping barb, the protection bin is arranged on the outside of the anchor rod body, the first push rod, the second push rod, the third push rod and the clamping barb are all located inside the protection bin, the first push rod is connected to the third push rod through the second push rod, the clamping barb is arranged on the outside of the first push rod, and the end of the third push rod is connected to the driving motor.

[0006] The rotating motor is used as the power source to drive the spiral push rod to rotate linearly and pierce the end wall of the mud bin. The electric push rod assembly provides thrust to enable the expansion assembly to expand or contract. The expansion assembly realizes opening and closing actions through the connecting rod structure. After the anchor rod is inserted into the soil, it is expanded to increase the anchoring force. The anchor head, as the front end part of the anchor rod, is directly inserted into the soil. The mud bin is used to store mud. The mud channel ensures that the mud can flow out smoothly and be distributed around the anchor rod to improve the anchoring force.

[0007] Furthermore, the inner wall of the front end of the mud bin inside the anchor body is made of thin-walled steel.

[0008] Furthermore, the spiral push rod is located inside the mud bin, and the front end of the spiral push rod is shaped like a conical spiral.

[0009] Furthermore, a sensor probe is provided at the mud channel, and a flow monitor and a buzzer are provided at the rear end of the anchor body. The mud channels are evenly spaced outside the anchor head, and the number is 24. The sensor probe is used to detect the flow of mud and transmit the data information to the flow monitor. The flow monitor receives the data information transmitted by the sensor probe and transmits the information to the buzzer. The buzzer is used to remind the operator to pay attention to the working status of the anchor.

[0010] Furthermore, a slider and a fixing block are arranged on the outer side of the anchor rod body, the slider is connected to the first push rod, and a first fixed pulley fixing piece and a second fixed pulley fixing piece are arranged on the outer side of the slider and the fixing block respectively.

[0011] Furthermore, the outward expansion component includes a first node, a second node, a third node, a sawtooth and an outward expansion connecting rod, one end of the outward expansion connecting rod is connected to the slider through a first fixed pulley fixing member, and the other end is connected to the fixed block through a second fixed pulley fixing member, the first node, the second node and the third node are all arranged on the outward expansion connecting rod, and the second node is located between the first node and the third node, the sawtooth is arranged on one side of the end of the outward expansion connecting rod, and the outward expansion connecting rod is a broken line shape.

[0012] Furthermore, the length of the rod body between the sliding block and the fixed block is 50-75 mm, and the length of the rod body between the first node, the second node and the third node gradually decreases.

[0013] Furthermore, a spring block is arranged on the outer side of the anchor rod body, and the spring block is located between the sliding block and the fixing block.

[0014] Working principle: Insert the anchor rod into the pre-drilled hole, connect the power supply, and turn on the electric push rod assembly and the switch of the internal circuit system to start the anchor rod. The mud bin is initially filled with mud, and the sensor probe has no mud flow signal, so the flow monitor has no data to display, and the buzzer remains silent. Start the rotating motor to drive the spiral push rod in the mud bin to rotate forward, and then the spiral push rod pierces the end wall of the mud bin to connect the mud bin with the mud channel. The mud in the mud bin flows into the mud channel through the rupture, and then flows into the soil along the mud channel and consolidates with the soil. At this time, the sensor probe detects the flow of mud and transmits the data information to the flow monitor. After the flow monitor processes the information, The signal is transmitted to the buzzer, which makes a sound to indicate that the mud is flowing. Subsequently, the multi-stage push rods inside the protection bin begin to extend, pushing the slider forward. The first push rod slowly extends out of the protection bin, and the spikes on it pierce into the soil. The expansion link begins to expand into the soil as the slider slides. When the slider slides over the spring block on the anchor rod, the serrations on the expansion link all pierce into the soil, and the expansion nodes of the expansion link complete the expansion. The spring prevents the slider from sliding backward, ensuring the stability and reliability of the expansion component. When the mud in the mud bin has completely flowed out and the flow monitor shows zero, the buzzer stops sounding, indicating that the grouting work of the anchor rod is completed, and the mud injection and the deployment and anchoring of the expansion component have been completed.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant features:

[0016] 1. The expansion process of the anchor rod expansion member is completely completed by the electric system, which greatly saves construction time and manpower. Even in relatively hard soil layers, the construction can be easily completed, thus improving work efficiency;

[0017] 2. The electric push rod assembly not only provides thrust for the expansion assembly, but also bears part of the shear force, which enhances the overall stability of the anchor rod. The thorn design on the first push rod makes the anchor rod more stable in the soil layer and not easy to slide or loosen;

[0018] 3. The mud chamber set in the anchor realizes the automation of the grouting process, which is convenient and simple to operate and improves the construction efficiency. The mud can flow smoothly into the mud channel and be evenly distributed around the anchor, which enhances the consolidation effect between the anchor and the soil.

[0019] 4. After the expansion rod is fully expanded, the anchoring force and pull-out resistance of the anchor rod are greatly improved. Under the action of the mud, the entire anchor rod is relatively stable as a whole, and it is not easy to loosen or slacken even over time. This avoids the secondary repair of the anchor rod to a certain extent and reduces the maintenance cost;

[0020] 5. The combination of sensor probe and flow monitor can monitor the flow of mud in real time, providing operators with accurate working status information. The setting of buzzer enables operators to be reminded in time when the mud runs out or abnormalities occur, which helps to avoid over-grouting or under-grouting. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1A rib-shaped electric anchor comprises an anchor body 1, a rotating motor 2, an electric push rod assembly 3, an external expansion assembly 4, an anchor head 5, a mud bin 6, a spiral push rod 7 and a mud channel 8. The mud bin 6 is opened inside the anchor body 1, the anchor head 5 is fixedly installed at the front end of the anchor body 1, the mud channel 8 is opened on the outside of the anchor head 5 and passes through the anchor head 5, the rotating motor 2 is fixedly installed inside the rear end of the anchor body 1 and is rotatably connected to the spiral push rod 7, the electric push rod assembly 3 and the external expansion assembly 4 are both fixedly installed on the outside of the anchor body 1, and the electric push rod assembly 3 is fixedly connected to the external expansion assembly 4 through a slider 12. The rotating motor 2 serves as a power source to drive the spiral push rod 7 to perform linear rotation and movement, and enable it to pierce the end wall of the mud bin 6. The electric push rod assembly 3 provides thrust to enable the expansion assembly 4 to expand or contract. The expansion assembly 4 realizes opening and closing actions through a connecting rod structure. After the anchor rod is inserted into the soil, it is expanded to increase the anchoring force. The anchor head 5, as the front end part of the anchor rod, is directly inserted into the soil. The mud bin 6 is used to store mud. The mud channel 8 ensures that the mud can flow out smoothly and be distributed around the anchor rod to improve the anchoring force.

[0031] like Figure 2 The inner wall of the front end of the mud bin 6 inside the anchor body 1 is made of thin-walled steel. Infrared spotlights and photoresistors are provided on both sides of the mud bin 6. When the mud flows out, the infrared spotlights will shine on the photoresistor. The spiral push rod 7 is located inside the mud bin 6, and the shape of the front end of the spiral push rod 7 is a conical spiral. It is convenient to pierce the end wall of the mud bin 6. A sensor probe 9 is fixedly installed at the mud channel 8, and a flow monitor 10 and a buzzer 11 are fixedly installed at the rear end of the anchor body 1. The number of mud channels 8 is 24. The sensor probe 9 is used to detect the flow of mud and transmit the data information to the flow monitor 10. The flow monitor 10 receives the data information transmitted by the sensor probe 9 and transmits the information to the buzzer 11. The buzzer 11 is used to remind the operator to pay attention to the working status of the anchor.

[0032] like Figures 3-4 The electric push rod assembly 3 includes a protection bin 31, a first push rod 32, a second push rod 33, a third push rod 34 and a thorn 35. The protection bin 31 is fixedly installed on the outside of the anchor rod body 1, and the first push rod 32, the second push rod 33, the third push rod 34 and the thorn 35 are all located inside the protection bin 31. The first push rod 32 is connected to the third push rod 34 through the second push rod 33. The thorn 35 is fixedly installed on the outside of the first push rod 32, and the end of the third push rod 34 is fixedly connected to the driving motor.

[0033] like Figures 5-6The slider 12 is sleeved on the outside of the anchor rod body 1, and the fixing block 13 is fixedly installed on the anchor rod by bolts. The slider 12 is connected to the first push rod 32. The first fixed pulley fixing member 121 and the second fixed pulley fixing member 131 are fixedly installed on the outside of the slider 12 and the fixing block 13, respectively, and the number of the first fixed pulley fixing member 121 and the second fixed pulley fixing member 131 is four. The slider 12 connects the electric push rod assembly 3 and the external expansion assembly 4 to transmit thrust or tension. The fixing block 13 serves as a fixed point to provide stable support and connection, ensuring that the external expansion assembly 4 has sufficient stability and bearing capacity when working.

[0034] like Figures 7 to 9 The expansion assembly 4 includes a first node 41, a second node 42, a third node 43, a sawtooth 44 and an expansion link 45. One end of the expansion link 45 is connected to the slider 12 through a first fixed pulley fixing member 121, and the other end is connected to the fixed block 13 through a second fixed pulley fixing member 131. The rod bodies of the expansion link 45 are hinged through the first node 41, the second node 42 and the third node 43. The sawtooth 44 is fixedly installed on one side of the expansion link 45, and its front angle is 5°, the rear angle is 40°, and the wedge angle of the sawtooth 44 is 45°, which ensures the effective engagement and stability of the sawtooth 44 during the anchoring process. The length of the rod body between the slider 12 and the fixed block 13 is 50-75 mm, and the rod body between the subsequent nodes is 100 mm long. The length of the body is reduced successively. The expansion connecting rod 45 is made of high-quality aluminum alloy material, which not only has excellent strength but also has good corrosion resistance, thereby ensuring the long service life of the connecting rod in harsh environments. When the expansion connecting rod 45 is fully retracted, that is, when the two rod bodies between the fixed block 13 and the slider 12 are in a 180° state, the contracted size is smaller than the diameter of the anchor head 5, effectively avoiding unnecessary friction resistance generated by the anchor rod body 1 during the lowering process. When the expansion connecting rod 45 is fully opened, a stable triangular structure is formed between the fixed block 13, the two rod bodies between the slider 12 and the anchor rod body 1, and this structure gives the anchor rod sufficient stability and bearing capacity during the anchoring process. A spring clamp 14 is installed on the outside of the anchor rod body 1, and the spring clamp 14 is located between the slider 12 and the fixed block 13. The spring clamp 14 uses the elastic force of the spring to achieve clamping and loosening actions, prevent the slider 12 from sliding back, and ensure the stability and reliability of the expansion component 4.
