Description

Technical Field

[0001] This utility model relates to the field of borehole inspection technology, specifically a borehole inspection device for bored piles. Background Technology

[0002] A borehole inspection tool is used to inspect the quality of bored piles. During the construction of bored piles, problems such as irregular hole shape, hole wall collapse, and excessive sediment buildup may occur due to geological conditions, construction techniques, and human factors. These problems can all affect the quality and safety of the pile foundation. Therefore, tools are needed to inspect the quality of bored piles, and the bored pile inspection tool is a commonly used inspection tool.

[0003] To facilitate the movement of the inspection device, a moving component is installed at the bottom of the frame. However, after the inspection device is moved to the required position, it does not have a limit function, which causes the inspection device to move during use, resulting in inaccurate inspection. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a borehole inspection device for bored piles, which has the advantages of limiting the inspection device and solving the problem that the inspection device does not have a limiting function.

[0005] This utility model discloses a borehole inspection device for cast-in-place piles, comprising a frame, inspection components mounted on the surface of the frame, movable components at the four corners of the frame's bottom, and limiting components on both sides of the frame. Each limiting component includes an electric push rod, the inner side of which is connected to the frame. A pressure plate is mounted at the output end of the electric push rod, and eight limiting teeth are evenly spaced at the bottom of the pressure plate. Sliding rods are mounted on both sides of the top of the pressure plate, with limiting blocks fixedly connected to the top of each sliding rod. A sliding sleeve is movably connected to the surface of each sliding rod, and the inner side of the sliding sleeve is fixedly connected to the frame. This utility model allows for movement when necessary. The moving component drives the frame to move. After the frame moves to the required position, the electric push rod operates, which drives the pressure plate to move downward. The sliding rod assists in moving the pressure plate downward, and the sliding sleeve assists in moving the sliding rod downward. The limiting block limits the sliding rod to move within the sliding sleeve. The pressure plate drives the limiting tooth to move downward. When the limiting tooth inserts into the soil, it increases the stability of the frame. This avoids the situation where the frame lacks the limiting function after moving to the required position, which would otherwise lead to poor inspection of the bored pile by the inspection component. At this time, the inspection component operates, and the bored pile can be inspected by the inspection component.

[0006] This utility model discloses a borehole inspection device for cast-in-place piles. The inspection assembly includes a frame fitted around the center of a machine frame. A motor is mounted on the top of the front of the frame, and a rotating rod is mounted on the output end of the motor. One end of the rotating rod extends through and into the inner cavity of the frame. A take-up roller is fixedly mounted on the surface of the rotating rod, and a traction rope is wound around the surface of the take-up roller. The end of the traction rope away from the take-up roller is fixedly connected to the inspection device body. An infrared ranging head is mounted on the bottom of the inspection device body. When inspection is required, the motor first runs, driving the rotating rod to rotate, which in turn drives the take-up roller to rotate, and the take-up roller drives the traction rope to release the line. At this time, the traction rope will drive the infrared ranging head and the inspection device body to move downwards. When the infrared ranging head and the inspection device body move into the borehole pile, the dimensions inside the borehole pile can be accurately measured. The measured data is then transmitted to an external receiving end through the inspection device body.

[0007] The borehole inspection device of this utility model has the motor fixedly connected to the frame at the top and bottom by a fixing bracket, and the motor is located at the center of the top front of the frame. The fixing bracket can fix the motor, so that the motor can perform better when used and avoid the motor shaking during use, which would lead to poor motor operation.

[0008] The present invention relates to a borehole inspection device for cast-in-place piles, wherein the end of the rotating rod away from the motor is rotatably connected to a movable shaft, and the other end of the movable shaft is fixedly connected to the inner wall of the frame. Through the movable shaft, the rotating rod can be stabilized during rotation, thus preventing the rotating rod from jamming.

[0009] The present invention relates to a borehole inspection device for cast-in-place piles, wherein the bottom of the front and back sides of the frame are fitted with fixing bolts, and the inner side of the fixing bolts is fixedly connected to the frame. The fixing bolts can fix the frame to the frame more stably, avoiding the frame from moving during use, which would lead to instability of the components inside the frame.

[0010] The present invention relates to a borehole inspection device for cast-in-place piles, wherein each of the four corners of the bottom of the frame is provided with a movable component, the movable component includes a fixed rod, the top of the fixed rod is fixedly connected to the frame, the bottom of the fixed rod is fixedly connected to a concave plate, the inner cavity of the concave plate is rotatably connected to a movable rod, and the surface of the movable rod is fitted with a pulley.

[0011] The borehole inspection device of this utility model has two ends of the top of the pressure plate and the connection of the slide rods fixedly connected by connecting blocks. The two slide rods are arranged symmetrically about the pressure plate. The connecting blocks can fix the slide rods, so that the slide rods are more effective in use and avoid the slide rods from becoming loose during use, which would cause the slide rods to move unsmoothly in the sliding sleeve.

[0012] The present invention relates to a borehole inspection device for cast-in-place piles, wherein both ends of the electric push rod are fixedly connected to mounting plates, and the inner cavity of the mounting plates is fixedly connected to the frame through mounting rods. The mounting plates and mounting rods can fix the electric push rod, thus improving the performance of the electric push rod during use and preventing it from shaking, which could lead to instability in the downward movement of the pressure plate driven by the electric push rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When the machine needs to be moved, the moving component drives the frame to move. After the frame moves to the required position, the electric push rod operates, which drives the pressure plate to move downward. The sliding rod assists the pressure plate to move downward, and the sliding sleeve assists the sliding rod to move downward. The limiting block limits the sliding rod to move within the sliding sleeve. The pressure plate drives the limiting tooth to move downward. When the limiting tooth is inserted into the soil, the stability of the frame is increased. This avoids the situation where the frame does not have the limiting function after moving to the required position, which would lead to poor hole inspection effect of the inspection component on the bored pile. At this time, the hole inspection component operates, and the bored pile can be inspected by the hole inspection component.

[0015] 2. When borehole inspection is required, the motor first runs, which drives the rotating rod to rotate, which in turn drives the winding roller to rotate, which in turn drives the traction rope to release the line. At this time, the traction rope will drive the infrared ranging head and the borehole inspector body to move downward. When the infrared ranging head and the borehole inspector body move into the drilled pile, the dimensions inside the drilled pile can be accurately measured. The measured data can be transmitted to the external receiving end through the borehole inspector body.

[0016] The mounting bracket can be used to fix the motor in place, which makes the motor perform better during use and prevents the motor from shaking, which would lead to poor motor performance.

[0017] The movable shaft can stabilize the rotation of the rotating rod, preventing it from jamming during rotation.

[0018] By using fixing bolts, the frame can be more stably fixed to the machine frame, preventing the frame from moving during use and thus avoiding instability of the components inside the frame.

[0019] The connecting block can fix the slide rod, which makes the slide rod perform better when used and avoids the slide rod becoming loose during use, which would cause the slide rod to move unsmoothly in the sliding sleeve.

[0020] The mounting plate and mounting rod can be used to fix the electric push rod, which makes the electric push rod more effective during use and avoids the situation where the electric push rod shakes during use, which would cause the pressure plate to move downwards unstably.

Detailed Implementation

[0027] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0028] Please see Figure 1-4 The present invention discloses a borehole inspection device for cast-in-place piles, comprising a frame 1, an inspection assembly 2 on the surface of the frame 1, movable assemblies 4 at the four corners of the bottom of the frame 1, and limiting assemblies 3 on both sides of the frame 1. Each limiting assembly 3 includes an electric push rod 301, the inner side of which is connected to the frame 1. A pressure plate 305 is provided at the output end of the electric push rod 301. Eight limiting teeth 306 are evenly spaced at the bottom of the pressure plate 305. Sliding rods 308 are provided on both sides of the top of the pressure plate 305. Limiting blocks 309 are fixedly connected to the top of the sliding rods 308. Sliding sleeves 304 are movably connected to the surface of the sliding rods 308, and the inner side of the sliding sleeves 304 is fixedly connected to the frame 1. When movement is required, the frame is moved by the movable assemblies 4. 1. The frame 1 is moved. After the frame 1 is moved to the required position, the electric push rod 301 is activated. The electric push rod 301 drives the pressure plate 305 to move downward. The sliding rod 308 assists in the downward movement of the pressure plate 305. The sliding sleeve 304 assists in the downward movement of the sliding rod 308. The limiting block 309 limits the movement of the sliding rod 308 within the sliding sleeve 304. The pressure plate 305 drives the limiting tooth 306 to move downward. When the limiting tooth 306 is inserted into the soil, the stability of the frame 1 is increased. This avoids the situation where the frame 1 does not have the limiting function after it is moved to the required position, which would lead to the poor inspection effect of the inspection component 2 on the bored pile. At this time, the inspection component 2 is activated, and the bored pile can be inspected by the inspection component 2.

[0029] The hole inspection assembly 2 includes a frame 201, which is fitted onto the center of the surface of the frame 1. A motor 204 is located at the top of the front of the frame 201. A rotating rod 209 is located at the output end of the motor 204. One end of the rotating rod 209 passes through and extends into the inner cavity of the frame 201. A take-up roller 202 is fixedly fitted onto the surface of the rotating rod 209. A traction rope 208 is wound around the surface of the take-up roller 202. The end of the traction rope 208 away from the take-up roller 202 is fixedly connected to the hole inspector body 207. An infrared ranging head 206 is located at the bottom of the hole inspector body 207. This utility model... When borehole inspection is required, motor 204 first starts running, which drives rotating rod 209 to rotate. Rotating rod 209 drives take-up roller 202 to rotate, which in turn drives traction rope 208 to release the line. At this time, traction rope 208 will drive infrared ranging head 206 and borehole inspector body 207 to move downward. When infrared ranging head 206 and borehole inspector body 207 move into the borehole pile, the dimensions inside the borehole pile can be accurately measured. The measured data is then transmitted to the external receiving end through borehole inspector body 207.

[0030] The top and bottom of the motor 204 are fixedly connected to the frame 201 by a fixing bracket 203. The motor 204 is located at the center of the top front of the frame 201. The fixing bracket 203 can fix the motor 204, so the motor 204 performs better when in use and avoids the motor 204 shaking during use, which would lead to poor operation of the motor 204.

[0031] The end of the rotating rod 209 away from the motor 204 is rotatably connected to a movable shaft 2010, and the other end of the movable shaft 2010 is fixedly connected to the inner wall of the frame 201. Through the movable shaft 2010, the rotating rod 209 can be stabilized when it rotates, thus avoiding the situation where the rotating rod 209 gets stuck when it rotates.

[0032] The bottom of the front and back of the frame 201 is fitted with fixing bolts 205, and the inner side of the fixing bolts 205 is fixedly connected to the frame 1. The fixing bolts 205 can fix the frame 201 to the frame 1 more stably, and prevent the frame 201 from moving during use, which would lead to the instability of the components inside the frame 201.

[0033] The four corners of the bottom of the frame 1 are provided with moving components 4. The moving components 4 include fixed rods 401. The top of the fixed rods 401 is fixedly connected to the frame 1. The bottom of the fixed rods 401 is fixedly connected to a concave plate 404. The inner cavity of the concave plate 404 is rotatably connected to a movable rod 403. The surface of the movable rod 403 is fitted with a pulley 402.

[0034] Both ends of the top of the pressure plate 305 are fixedly connected to the slide rod 308 by connecting blocks 307. The two slide rods 308 are arranged symmetrically about the pressure plate 305. The connecting blocks 307 can fix the slide rods 308, so that the slide rods 308 can perform better in use and avoid the slide rods 308 from becoming loose during use, which would cause the slide rods 308 to move unsmoothly in the sliding sleeve 304.

[0035] Both ends of the electric push rod 301 are fixedly connected to mounting plates 302, and the inner cavity of the mounting plate 302 is fixedly connected to the frame 1 through the mounting rod 303. The mounting plate 302 and the mounting rod 303 can fix the electric push rod 301, so that the electric push rod 301 performs better when in use and avoids the electric push rod 301 shaking during use, which would cause the electric push rod 301 to drive the pressure plate 305 to move downwards unstably.

[0036] When using this utility model: when movement is required, the frame 1 is moved by the moving component 4. After the frame 1 is moved to the required position, the electric push rod 301 is activated, which drives the pressure plate 305 to move downward. The sliding rod 308 assists the pressure plate 305 to move downward, and the sliding sleeve 304 assists the sliding rod 308 to move downward. The limiting block 309 limits the sliding rod 308 to move within the sliding sleeve 304. The pressure plate 305 drives the limiting tooth 306 to move downward. When the limiting tooth 306 is inserted into the soil, the stability of the frame 1 is increased. This avoids the situation where the frame 1 does not have the limiting function after it is moved to the required position, which would lead to the hole inspection component 2 not being effective in inspecting the bored pile. At this time, the hole inspection component 2 is activated, and the bored pile can be inspected by the hole inspection component 2.

[0037] When borehole inspection is required, motor 204 first runs, driving rotating rod 209 to rotate, which in turn drives take-up roller 202 to rotate, which in turn drives traction rope 208 to release the line. At this time, traction rope 208 will drive infrared ranging head 206 and borehole inspector body 207 to move downward. When infrared ranging head 206 and borehole inspector body 207 move into the drilled pile, the dimensions inside the drilled pile can be accurately measured. The measured data is then transmitted to the external receiving end through borehole inspector body 207.

[0038] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
