Description

Technical Field

[0001] This utility model belongs to the field of pile hole detection technology, specifically relating to a pile hole detection device for engineering construction. Background Technology

[0002] Piling is a type of foundation treatment. Piling is formed by drilling and pouring concrete to enhance the bearing capacity of the foundation. Therefore, during the construction process, it is often necessary to excavate pile holes to lay a solid foundation for a building. To ensure the quality of the pile holes, various data of the pile holes need to be tested after the pile holes are formed. Among them, the diameter test of the pile holes is particularly important.

[0003] In related existing technologies, such as Chinese Patent No. CN222733572U, a pile hole diameter detection device for engineering management is disclosed. This device includes a support platform with four casters fixedly connected to the four corners of its bottom. A support frame is fixedly connected to the bottom of the support platform via screws. A motor is fixedly connected to the inner wall of the support frame, and an output rod is fixedly connected to the top output end of the motor. This solution uses a push rod, specifically an auxiliary block, to support the electric push rod. This allows the push rod to adjust the support block, positioning it at the top of the pile hole. The adjusting threaded rod can then be moved downwards or upwards via a rotating ring, causing the adapter ring to move downwards or upwards. This facilitates the placement of the adapter ring inside the pile hole for diameter detection, significantly reducing the complex procedures of manually assembling measuring equipment and streamlining the pile hole detection process, thereby saving manpower and improving detection efficiency.

[0004] However, in actual use, when the above-mentioned device detects the diameter of the pile hole, the rotating ring is located above the pile hole and needs to be manually controlled. The diameter of the pile hole is usually between 0.8-2.5m and the depth is relatively deep. The method of manually rotating the rotating ring is not safe, and workers are prone to slipping and falling into the pile hole. Moreover, when the diameter is large, such as 2.5m, it is difficult for workers on the ground to reach the rotating ring. In other words, it is difficult to manually control the rotation of the rotating ring, which makes it difficult for the detection end of the above-mentioned scheme to enter the pile hole under human control. Utility Model Content

[0005] The present invention aims to provide a pile hole detection device for engineering construction, which is safer to operate and easier for workers to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pile hole detection device for engineering construction, comprising...

[0007] The trolley has a mounting bracket on top, with a multi-stage telescopic rod fixed on the mounting bracket, and clearance holes are provided on the trolley.

[0008] The diameter detection mechanism includes a control motor, a transmission assembly, and two abutment plates. The control motor is installed at the movable end of the multi-stage telescopic rod. The transmission assembly is connected to the control motor. The two abutment plates are connected to the transmission assembly and are symmetrically arranged on both sides of the control motor. The transmission assembly is driven by the control motor to move the two abutment plates closer to or further apart from each other. A rangefinder and a reflector are respectively installed on the opposite side of the two abutment plates.

[0009] The principle and effects of this technical solution:

[0010] 1. The installation frame and multi-stage telescopic rods allow the multi-stage telescopic rods to be installed on the trolley and above the ground. When not in use, the diameter detection mechanism can be stored above the ground and inside the installation frame to avoid interference between the trolley and the ground. When in use, the extension and retraction of the multi-stage telescopic rods drive the diameter detection mechanism deeper into the pile hole without manual operation, improving the safety of the device. Workers can also control the device through the control panel, making it more convenient to use.

[0011] 2. By controlling the motor to drive the transmission assembly, the two abutting plates can move away from each other and abut against the inner wall of the pile hole. With the setting of the rangefinder and reflector, after the abutting plates on both sides abut against the inner wall of the pile hole, the inner diameter of the pile hole can be measured by the rangefinder. The whole process does not require manual operation of the mechanical body of the detection end, only the control end needs to be controlled.

[0012] The present invention is further configured as follows: the transmission assembly includes a drive screw, a fixed plate, a movable plate, a first transmission rod, a second transmission rod, a transmission plate, and a limiting plate; a control motor is fixed on the fixed plate; a protective cover is fixed on the fixed plate; the protective cover is fixed to the movable end of the multi-stage telescopic rod; the drive screw is rotatably mounted on the bottom of the fixed plate and is connected to the movable end of the control motor; a transmission plate is mounted on the side wall of the abutment plate; a first transmission rod and a second transmission rod are rotatably mounted on the transmission plate; the end of the first transmission rod is rotatably connected to the fixed plate; the end of the second transmission rod is rotatably connected to the movable plate; the movable plate is threaded onto the drive screw; the limiting plate is mounted on the bottom of the drive screw; and the rangefinder and the reflector are respectively disposed on opposite sides of the two transmission plates.

[0013] The principle and effect of this technical solution are as follows: By controlling the motor to drive the drive screw to rotate, the drive screw can drive the movable plate to move. The connection between the first transmission rod and the fixed plate restricts the rotation of the transmission plate, which in turn restricts the rotation of the second transmission rod connected to the transmission plate and the movable plate connected to the second transmission rod. That is, controlling the motor to drive the drive screw to rotate can make the movable plate move up and down along the drive screw. By moving the movable plate up and down, the distance and angle between the first and second transmission rods are changed. As the distance and angle between the first and second transmission rods change, the distance between the transmission plate and the drive screw also changes. This achieves the effect of driving the abutment plate to abut against the inner wall of the pile hole and away from the inner wall of the pile hole. Moreover, by setting it on both sides, the abutment plates on both sides can be controlled synchronously.

[0014] The present invention is further configured to include a spring-loaded assembly, which includes a connecting rod, a connector, and a spring. The connecting rod is slidably inserted into the transmission plate. One end of the connecting rod is fixed to the abutment plate, and the other end of the connecting rod is fixed to the connector. The connector abuts against the side of the transmission plate away from the abutment plate. The spring is fitted onto the connecting rod and is located between the abutment plate and the transmission plate. A rangefinder is fixed to one side of the connector, and a reflector is fixed to the other side of the connector.

[0015] The principle and effect of this technical solution: By setting the connecting rod and the connecting head, the abutment plate can move horizontally relative to the transmission plate. Furthermore, by setting the spring, the abutment plate has a tendency to spontaneously move away from the transmission plate. When the abutment plate abuts against the inner wall of the pile hole, after the abutment plate is pressed against the pile hole wall, the control motor can also drive the drive screw to rotate and drive the movable plate to move, thereby further unfolding the first transmission rod and the second transmission rod to ensure that the abutment plate is fully pressed against the pile hole wall.

[0016] The present invention is further configured such that: the diameter detection mechanism also includes a stabilizing frame, the cross-section of the stabilizing frame is "C" shaped, one end of the stabilizing frame is connected to the fixing plate, and the other end of the stabilizing frame is connected to the limiting plate.

[0017] The principle and effect of this technical solution: By setting up the stabilizing frame, the position of the limiting plate can be reinforced, so that the drive screw can rotate stably between the fixed plate and the limiting plate.

[0018] The present invention is further configured such that a ball bearing is installed on the side of the abutment plate away from the control motor.

[0019] The principle and effect of this technical solution: By setting the ball bearings, the friction between the abutment plate and the inner wall of the pile hole is changed from sliding friction to rolling friction, resulting in a smaller coefficient of friction, less wear during testing and use, longer service life, and less frictional resistance when moving up and down against the inner wall of the pile hole.

[0020] The present invention is further configured such that a pressure sensor is provided inside the abutment plate.

[0021] The principle and effect of this technical solution: By setting up a pressure sensor, the user can stop the motor in time based on the feedback from the pressure sensor when controlling the motor to avoid excessive stretching and damage to the diameter detection mechanism.

[0022] The present invention is further configured such that the cross-section of the abutment plate is arc-shaped.

[0023] The principle and effect of this technical solution: By setting the arc shape, the shape of the abutment plate can better fit the shape of the pile hole.

[0024] The present invention is further provided that the outer wall of the trolley has a threaded hole.

[0025] The principle and effect of this technical solution: When the diameter of the pile hole is large (such as 2.5 meters), an extension rod can be threaded into the side wall of the trolley through the threaded hole. The extension rod contacts the ground, thereby hanging the trolley above the pile hole to achieve the detection effect. At the same time, it can reduce the size of the trolley, making the space required by the trolley smaller and facilitating the transportation and carrying of the trolley. Attached Figure Description

[0037] Example:

[0038] As attached Figure 1-5 As shown, this utility model discloses a pile hole detection device for engineering construction, including a trolley 110, a spring-loaded component, and a diameter detection mechanism. A mounting frame 120 is installed on the top of the trolley 110, and a multi-stage telescopic rod 130 is fixed on the mounting frame 120 (the multi-stage telescopic rod 130 is a multi-stage linkage electric telescopic cylinder, which is a commercially available product and will not be described in detail here). A clearance hole 111 is provided on the trolley 110, and the movable end of the multi-stage telescopic rod 130 and the diameter detection mechanism can both pass through the clearance hole 111.

[0039] The diameter detection mechanism includes a control motor 210, a transmission assembly, and two abutment plates 220. The two abutment plates 220 are connected to the transmission assembly and are symmetrically arranged on both sides of the control motor 210. The transmission assembly includes a drive screw 310, a fixed plate 320, a movable plate 330, a first transmission rod 340, a second transmission rod 350, a transmission plate 360, and a limiting plate 370. The control motor 210 is fixed to the fixed plate 320, and a protective cover 211 is fixed to the fixed plate 320. The protective cover 211 is connected to the movable multi-stage telescopic rod 130. The drive screw 310 is rotatably mounted on the bottom of the fixed plate 320 and is connected to the movable end of the control motor 210. A transmission plate 360 ​​is installed on the side wall of the abutment plate 220. A first transmission rod 340 and a second transmission rod 350 are rotatably mounted on the transmission plate 360. The end of the first transmission rod 340 is rotatably connected to the fixed plate 320, and the end of the second transmission rod 350 is rotatably connected to the movable plate 330. The movable plate 330 is threaded onto the drive screw 310, and a limiting plate 370 is installed at the bottom of the drive screw 310.

[0040] The spring-loaded assembly includes a connecting rod 410, a connector 420, and a spring 430. The connecting rod 410 is slidably inserted into the transmission plate 360. One end of the connecting rod 410 is fixed to the abutment plate 220, and the other end of the connecting rod 410 is fixed to the connector 420, which abuts against the side of the transmission plate 360 ​​away from the abutment plate 220. The spring 430 is fitted onto the connecting rod 410 and located between the abutment plate 220 and the transmission plate 360. A rangefinder 230 is fixed to one side of the connector 420, and a reflector 240 is fixed to the other side of the connector 420. In this scheme, one transmission plate 360 ​​corresponds to two sets of spring-loaded components, that is, there are four sets of spring-loaded components, corresponding to four connectors 420. Two connectors 420 on the same side are respectively equipped with a rangefinder 230 and a reflector 240. Two connectors 420 on the other side are also equipped with a rangefinder 230 and a reflector 240. The positions of the rangefinder 230 and the reflector 240 on different sides correspond. The rangefinder 230 can be an infrared rangefinder 230 or a laser rangefinder 230. The reflector 240 is used to accurately reflect the beam of the rangefinder 230, reduce energy loss, and improve detection accuracy.

[0041] The diameter detection mechanism also includes a stabilizing frame 380, which has a C-shaped cross-section. One end of the stabilizing frame 380 is connected to the fixing plate 320, and the other end is connected to the limiting plate 370. A ball bearing 221 is installed on the side of the abutment plate 220 away from the control motor 210. A pressure sensor is installed inside the abutment plate 220. The ball bearing 221 presses against the pressure sensor. The pressure exerted by the ball bearing 221 determines the degree of contact between the abutment plate 220 and the inner wall of the pile hole, thereby determining whether to continue rotating the drive screw 310. The cross-section of the abutment plate 220 is arc-shaped.

[0042] The trolley 110 is equipped with a control module and a power supply. The control module is used to receive or send information about the pressure sensor, rangefinder 230, control motor 210, and multi-stage telescopic rod 130. The control module is connected to the power supply, and staff can control the various electronic components through the control module. The control module and power supply are commonly used electronic components, such as control panels, which are commercially available products and are not covered by this solution. They are only used as a supplement to the completeness of the solution.

[0043] The trolley 110 has threaded holes 112 on its outer wall. Each of the four outer side walls of the trolley 110 has two threaded holes 112. The threaded holes 112 can be used to insert threaded rods. By inserting threaded rods, the coverage area of ​​the trolley 110 can be extended, allowing the trolley to be hung above pile holes with a large diameter, such as 2.5 meters. When the trolley 110 needs to be suspended above the pile hole, although the overall weight of the device is not large, at least three people should work together to set it up, or a hoisting device should be used in conjunction with manpower to set it up on the pile hole to ensure safety.

[0045] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.
