For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.
[0029] like Figure 1-2 As shown, an embodiment of the utility model is an automatic sinking device for an expanded body anchor rod, comprising a support platform 1, a first movable arm and a second movable arm. The support platform 1 is arranged at the sinking position of the expanded body anchor rod 12, and a through hole is arranged in the center of the support platform 1, and the through hole is aligned with the anchor hole 13 at the sinking position. On the support platform 1, a first movable arm and a second movable arm are arranged in sequence along the sinking direction of the expanded body anchor rod 12, and the first movable arm is arranged above the second movable arm. The first movable arm can clamp the expanded body anchor rod 12 and move it toward the second movable arm, so that the expanded body anchor rod 12 passes through the support platform 1 and gradually sinks at the sinking position. During the gradual sinking process, the second movable arm can clamp and fix the expanded body anchor rod 12.
[0030] Specifically, in order to ensure that the expanded body anchor rod 12 can sink steadily, multiple first movable arms and second movable arms are provided, and are evenly arranged along the circumference of the anchor rod. In this embodiment, three first movable arms and three second movable arms are provided, and are evenly arranged along the circumference of the expanded body anchor rod 12. The upper first movable arm and the lower second movable arm are aligned. The first movable arm and the second movable arm can clamp the expanded body anchor rod 12 in three directions.
[0031] Specifically, in order to facilitate the installation of the first movable arm and the second movable arm, a support frame 2 is installed on the upper part of the support platform 1. The ends of the first movable arm and the second movable arm away from the expansion anchor rod 12 are arranged on the support frame 2. In this embodiment, the support frame 2 is a triangular cylinder, and the bottom is fixedly connected to the support platform 1. The through hole on the support platform 1 is located at the center of the triangular cylinder.
[0032] Specifically, the first movable arm and the second movable arm both include a linear module 3 and a telescopic arm 5. The linear module 3 is also called a linear module, which can drive the load to perform linear motion through a slider 4. It is a prior art, and the specific structure is not described here. The linear module 3 is vertically arranged along the height of the support frame 2, and the linear modules 3 of the first movable arm and the second movable arm are aligned. The telescopic arm 5 is arranged horizontally, and can be close to or away from the expansion anchor rod 12 to clamp or release the expansion anchor rod 12. The end of the telescopic arm 5 away from the expansion anchor rod 12 is fixed on the slider 4, and the linear module 3 can drive the telescopic arm 5 to move up and down. In this embodiment, the telescopic arm 5 is specifically an electric telescopic rod. The initial position of the telescopic arm 5 of the first movable arm is set at the top of the support frame 2, and the position of the telescopic arm 5 of the second movable arm is set at the bottom of the support frame 2. A spacing is set between the telescopic arms 5 of the first movable arm and the second movable arm. The spacing is the sinking depth of the expansion anchor rod 12 each time it sinks step by step. The specific heights of the telescopic arms 5 of the first movable arm and the second movable arm can be set according to the length of the expanded body anchor rod 12 and the actual working conditions. The telescopic arm 5 of the first movable arm moves close to the expanded body anchor rod 12, and the three first movable arms clamp and fix the expanded body anchor rod 12 in three directions. The linear module 3 of the first movable arm drives the telescopic arm 5 of the first movable arm to move downward through the slider 4, and under the clamping action of the telescopic arm 5 of the first movable arm, drives the expanded body anchor rod 12 to move downward. When the telescopic arm 5 of the first movable arm moves downward to the top of the telescopic arm 5 of the second movable arm, the telescopic arm 5 of the second movable arm extends out to clamp the expanded body anchor rod 12. The telescopic arm 5 of the first movable arm shrinks and moves upward to the initial position, then extends out to clamp the expanded body anchor rod 12, and at this time, the telescopic arm 5 of the second movable arm shrinks. The first movable arm and the second movable arm repeat the above actions, gradually driving the expanded body anchor rod 12 to sink vertically along the anchor hole 13.
[0033] Preferably, in order to facilitate the telescopic arm 5 to clamp the expanded anchor rod 12, an arc plate 6 is fixed to one end of the telescopic arm 5 close to the expanded anchor rod 12, and the arc plate 6 is adapted to the outer wall of the expanded anchor rod 12. The telescopic arm 5 can drive the arc plate 6 to approach or move away from the expanded anchor rod 12 to clamp or release the expanded anchor rod 12.
[0034] Preferably, Figure 2 As shown, in order to prevent sliding between the arc plate 6 and the expanded anchor rod 12, a friction pad 7 is fixed on the side of the arc plate 6 close to the expanded anchor rod 12, so that the sinking of the expanded anchor rod 12 is more stable, and the shape of the friction pad 7 is adapted to the shape of the arc plate 6. The material of the friction pad 7 is not limited.
[0035] Preferably, Figure 2As shown, in order to facilitate the detection of the distance between the telescopic arms 5 of the first moving arm and the second moving arm, a position sensor 8 is provided at the relative position of the linear module 3 of the first moving arm and the slider 4 of the linear module 3 of the second moving arm. The position sensor 8 is a through-shooting sensor. The position sensor 8 on the first moving arm is installed below the slider 4 of the first moving arm, and the position sensor 8 on the second moving arm is installed above the slider 4 of the second moving arm. By setting the position sensor 8, the position information of the telescopic arm 5 of the first moving arm can be detected. When the position sensor 8 detects that the telescopic arm 5 of the first moving arm descends to the top of the telescopic arm 5 of the second moving arm, the telescopic arm 5 of the first moving arm stops moving downward, and the telescopic arm 5 of the second moving arm extends to clamp the expansion anchor rod 12. When the position sensor 8 detects that the telescopic arm 5 of the first moving arm rises to the initial position, the telescopic arm 5 of the first moving arm stops moving upward and extends to clamp the expansion anchor rod 12, and the telescopic arm 5 of the second moving arm contracts.
[0036] Preferably, Figure 3 As shown, a support rod 9 is provided on the support platform 1, and a measuring instrument 10 is provided at the calibrated height of the support rod 9, which is used to measure the distance h1 between the top of the expanded body anchor rod 12 and the calibrated height. The calibrated height is the set height h2, the height of the support platform 1 is h3, and the total length of the expanded body anchor rod 12 is h4, and the sinking depth h=h4-(h2+h3-h1) of the expanded body anchor rod 12 can be calculated. In this embodiment, the measuring instrument 10 is an infrared measuring instrument, and the installation position of the measuring instrument 10 is higher than the top of the support frame 2, that is, the height of the support frame 2 cannot affect the measurement of the measuring instrument 10. The infrared measuring instrument emits infrared rays to the top of the expanded body anchor rod 12, and by measuring the time from the emission of the infrared rays to the reception of the infrared rays, and combining the propagation speed of the infrared rays, h1 can be calculated. The infrared measuring instrument is a prior art and will not be described here.
[0037] Preferably, in order to make the measurement more accurate, a plurality of support rods 9 and measuring instruments 10 may be provided, arranged along the circumference of the support frame 2. In this embodiment, two support rods 9 are provided along the circumference of the support frame 2, and a measuring instrument 10 is installed on each support rod 9.
[0038] Specifically, in order to facilitate the movement of the entire device, a universal wheel 11 is installed at the bottom of the support platform 1. In order to ensure the stable sinking of the expansion anchor rod 12, a brake device is installed on the universal wheel 11, which is a prior art and the specific structure is not repeated here.
[0039] A method for using an automatic sinking device for an expanded anchor rod comprises the following steps:
[0040] 1. According to the actual situation at the construction site, the automatic sinking device of the expanded anchor rod is moved to the sinking position through the support platform 1 and the universal wheel 11 for positioning, so that the through hole of the support platform 1 is aligned with the anchor hole 13.
[0041] 2. Use construction machinery to lift the expanded anchor rod 12 to the top of the entire device, and prepare to start the sinking construction.
[0042] 3. The construction machinery slowly lowers the expanded anchor rod 12 into the support frame 2. When the bottom of the expanded anchor rod 12 drops below the telescopic arm 5 of the first movable arm, the telescopic arm 5 of the first movable arm located at the upper part extends out and clamps and fixes the expanded anchor rod 12 through the arc plate 6.
[0043] 4. Driven by the construction machinery and the linear module 3 of the first movable arm, the expanded anchor rod 12 moves downward. During the movement, the friction pad 7 can prevent the arc plate 6 and the expanded anchor rod 12 from sliding relative to each other, thereby ensuring the stability of the movement.
[0044] 5. When the position sensor 8 detects that the telescopic arm 5 of the first movable arm moves down to above the telescopic arm 5 of the second movable arm, the telescopic arm 5 of the second movable arm extends to clamp and fix the expanded anchor rod 12, and the construction machinery releases the expanded anchor rod 12 at this time.
[0045] 6. The telescopic arm 5 of the first movable arm contracts and moves upward. When the position sensor 8 detects that the telescopic arm 5 of the first movable arm rises to the initial position, the telescopic arm 5 of the first movable arm stops rising.
[0046] 7. The telescopic arm 5 of the first moving arm extends to clamp and fix the expanded anchor rod 12, and the telescopic arm 5 of the second moving arm retracts. The first moving arm and the second moving arm repeat the actions in steps 4-6, driving the expanded anchor rod 12 to gradually sink to the required depth. After the sinking is completed, the distance h1 between the top of the expanded anchor rod 12 and the calibrated height can be measured by the measuring instrument 10, and the final sinking depth of the expanded anchor rod 12 can be calculated by h=h4-(h2+h3-h1) to check whether it meets the construction requirements.
[0047] The advantages and positive effects of the utility model are:
[0048] 1. The automatic sinking of the expanded anchor rod is realized by setting the first movable arm and the second movable arm, which speeds up the sinking speed and improves the construction efficiency.
[0049] 2. By setting up the linear module, the verticality of the expansion anchor rod sinking is ensured, the tilting and deviation of the expansion anchor rod during the sinking process is avoided, and the construction quality is improved.
[0050] 3. By setting up a measuring instrument, the final sinking depth of the expanded anchor rod can be detected, further ensuring the construction quality.
[0051] 4. The first movable arm and the second movable arm can firmly clamp the expanded anchor rod. The stability of the clamping is further guaranteed by setting the friction pad, thereby ensuring the stability and safety of the expanded anchor rod during the sinking process.
[0052] 5. Reduce labor consumption, reduce labor costs, simple structure and convenient operation.
[0053] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
