Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation detection equipment, and particularly relates to a pile foundation flatness detection device using a self-balancing method. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is simply called a pile foundation. Pile foundation flatness detection is extremely important in pile foundation construction and inspection, because the verticality or flatness of the pile foundation is one of the key factors affecting its bearing capacity and stability. If there is a problem with the flatness of the pile foundation, it may cause uneven settlement or even damage to the structure. Therefore, this device plays an important role in construction quality control. The self-balancing method is a measurement method that does not require an external reference. It is usually used in situations where the construction site is more complex or external references are difficult to obtain. This method uses the balance component inside the device to determine the balance state of the device, and then determines the deviation of the pile foundation from this known "balanced" state through the measurement system. Such a device can automatically compensate for some factors that may affect the measurement, such as vibration or temperature changes.

[0003] For example, a Chinese utility model patent with announcement number CN220318598U discloses a pile foundation detection device, which drives a contact plate to fit tightly against the surface to be tested of the pile foundation, detects the distance between the contact plate and the main pipe through a distance sensor to obtain a detection result 1 of the flatness of the surface to be tested of the pile foundation, detects the elastic force of the spring through a pressure sensor, indirectly obtains the downward movement distance of each piston, and then indirectly obtains a detection result 2 of the flatness of the surface to be tested of the pile foundation. By comparing the two detection results, the final detection result is obtained, and the detection is more accurate and reliable.

[0004] However, when the device is actually used, small gravel is likely to remain on the surface of the pile foundation, which can easily affect the accuracy of the flatness test results. In order to prevent the above situation from occurring, the surface of the pile foundation to be tested can only be manually cleaned in advance, and the process is relatively cumbersome.

[0005] In summary, there is currently a need for a pile foundation flatness detection device that can be pre-cleaned before detection. Utility Model Content

[0006] The utility model aims to provide a self-balancing pile foundation flatness detection device. While the electric push rod pushes the flatness detector to detect the surface of the pile foundation, the bristles at the bottom of two sets of slides are moved to both sides at the same time, so that the small gravel on the pile foundation surface to be tested is cleaned to both sides, thereby ensuring the accuracy of the detection result.

[0007] The utility model solves the above problems by adopting a technical solution: a self-balancing pile foundation flatness detection device, comprising:

[0008] A base, wherein the base is a rectangular frame structure, a connecting seat is arranged on the inner side of the base, a bracket is fixedly connected to the top of the connecting seat, an electric push rod is fixedly connected to the top center of the bracket, a connecting plate is fixedly connected to the telescopic end of the electric push rod, and a flatness detector is fixedly connected to the bottom of the connecting plate;

[0009] A pile foundation surface cleaning component includes a cross bar symmetrically fixedly connected to the top of a connecting seat, and slide plates are symmetrically slidably connected to the outside of both sides of the cross bar. Bristles are evenly arranged on the bottom of the slide plate, and a connecting rod is hinged between the slide plate and the connecting plate through a hinge.

[0010] A further preferred technical solution is that it also includes a cleaning device dust removal assembly, which includes sliding rods symmetrically fixedly connected to both sides of the slide, the sliding rods are slidably connected to sliding bars on the outside, a blocking rod is fixedly connected between the two groups of sliding bars, and the sliding rods are provided with a spring on the outside.

[0011] A further preferred technical solution is that the dust removal assembly of the cleaning device also includes a straight rod fixedly connected to the inner side of the connecting seat, the end of the straight rod is fixedly connected to a first magnet block, and the outer side of the sliding bar is fixedly connected to a second magnet block for adsorbing the first magnet block.

[0012] A further preferred technical solution is that the center of the first magnet block and the center of the second magnet block on the same side are on the same horizontal line.

[0013] A further preferred technical solution is that a screw rod is rotatably connected to one side of the connecting seat and the screw rod is threadedly connected to the base.

[0014] A further preferred technical solution is that a handwheel is fixedly connected to the end of the screw rod.

[0015] A further preferred technical solution is that a guide block is fixedly connected to the side of the connecting seat, and guide grooves are symmetrically provided on the inner side surface of the base and are slidably connected to the guide block.

[0016] A further preferred technical solution is that: the bottom of the base is rotatably connected with a moving wheel.

[0017] A further preferred technical solution is that a push handle is fixedly connected to the side of the base.

[0018] A further preferred technical solution is that the length of the blocking rod is greater than the length of the sliding plate.

[0019] In summary, the utility model has the following benefits:

[0020] 1. The utility model uses an electric push rod to push the flatness detector to detect the surface of the pile foundation. At the same time, the hinged effect between the connecting plate and the slide plate and the connecting rod, and the sliding cooperation between the slide plate and the cross bar can be used to push the bristles at the bottom of the two sets of slide plates to move to both sides at the same time, so that the small gravel on the surface to be tested of the pile foundation can be cleaned to both sides, thereby ensuring the accuracy of the detection result.

[0021] 2. In the process of pushing the two groups of slides to both sides, the utility model will also drive the slide bar to move with the slide bar. When the second magnet block on the slide bar contacts the first magnet block on the straight rod, the two will be adsorbed together. When the detection is completed and the flatness detector is driven to rise, the two groups of slide bars can be driven to move inward at the same time. At this time, the slide bar and the slide rod are used to slide together, and the slide bar will squeeze the spring. When the spring is compressed to the maximum contraction amount, as the slide bar continues to move, the first magnet block will separate from the second magnet block. The rebound effect of the spring will be used to make the slide bar drive the baffle bar to quickly reset. During the resetting process, the baffle bar will move the bristles, so that dust and impurities attached to the bristles can be shaken off, thereby ensuring a good cleaning effect of the bristles.

[0032] The pile foundation surface cleaning assembly includes a cross bar 101 symmetrically fixedly connected to the top of the connecting seat 2, and a slide plate 102 is symmetrically slidably connected to the outside of the two sides of the cross bar 101, and bristles 103 are evenly arranged on the bottom of the slide plate 102. A connecting rod 104 is hinged between the slide plate 102 and the connecting plate 5 through a hinge;

[0033] The cleaning device dust removal component includes a slide bar 201 symmetrically fixedly connected to both sides of the slide plate 102, the slide bar 201 is slidably connected to the outside of the slide bar 201, a baffle 203 is fixedly connected between the two sets of slide bars 202, the slide bar 201 is externally sleeved with a spring 204, the length of the baffle 203 is greater than the length of the slide plate 102, and can ensure the thoroughness of the cleaning of the bristles 103, the horizontal position of the baffle 203 is flush with the horizontal position of the middle of the bristles 103, so as to better shake off the dust and impurities on the bristles 103.

[0034] The cleaning device dust removal assembly also includes:

[0035] Four groups of straight rods 205 are symmetrically fixedly connected to the inner side of the connecting seat 2, the ends of the straight rods 205 are fixedly connected to the first magnet block 206, and the outside of the sliding bar 202 is fixedly connected to the second magnet block 207.

[0036] The implementation principle of a self-balancing pile foundation flatness detection device in the embodiment of the present application is as follows: first, the device is placed in the specified position, and then the hand wheel is turned to drive the screw rod 7 to rotate, and the sliding cooperation between the guide block 8 and the guide groove is utilized to push the connecting seat 2 to move horizontally, so that the position adjustment of the flatness detector 6 can be achieved, and then the electric push rod 4 is started, and the electric push rod 4 can push the flatness detector 6 to approach the pile foundation surface to be tested for detection, and the connection plate 5 and the hinge between the slide plate 102 and the connecting rod 104, and the sliding cooperation between the slide plate 102 and the cross bar 101 are utilized, so that the flatness detector 6 can push the bristles 103 at the bottom of the two groups of slide plates 102 to move to both sides at the same time during the descent process, so that the small gravel on the pile foundation surface to be tested can be cleaned to both sides, thereby ensuring the accuracy of the detection result, and when the two groups of slide plates 102 are pushed to move to both sides, During the process, the slider 202 will also be driven to move with the slide plate 102.
