Description

Technical Field

[0001] The utility model belongs to the technical field of PHC pipe pile detection, and in particular relates to a PHC pipe pile core detection device. Background Art

[0002] Among renewable energy sources, wind power and photovoltaic power generation are among the fastest growing emerging industries in the world, especially in recent years, China's wind power and photovoltaic power generation industries have developed rapidly. With the continuous increase of wind power and photovoltaic projects in China, wind power and photovoltaic construction projects are also increasing, and the market is getting bigger and bigger.

[0003] During the construction of wind power and photovoltaic projects, in order to shorten the construction period, speed up the construction, and put into production and generate electricity as soon as possible, most projects choose PHC prefabricated pipe piles, i.e. prestressed high-strength concrete pipe piles, for construction based on the actual construction period on site.

[0004] At present, one of the main factors that determine the strength and construction accuracy of PHC piles is the uniformity of the pile wall thickness, especially for PHC piles with pile shoes in wind power projects. If the center of the pile shoe does not coincide with the center of the pile, the pile will deviate from the designed pile center during construction, resulting in rework and other consequences, causing huge waste and increasing construction costs.

[0005] Due to the above reasons, it is necessary and urgent to provide a PHC pipe pile core detection tool that is easy to use on site and has high accuracy. Utility Model Content

[0009] The pile circumferential fixing mechanism comprises a plurality of first connecting tubes, hinged tubes and first adjusting screws; adjacent first connecting tubes are respectively hingedly connected by hinged tubes to form a straight-line and bendable integral structure; first adjusting screws are respectively connected to the first connecting tubes at both ends.

[0010] The first connecting tube is an aluminum alloy square tube; both ends of the first connecting tube are symmetrically provided with hinge holes penetrating the upper and lower surfaces.

[0013] The lengths of the hinged tube and the first connecting tube are 200-300 mm and 400-500 mm respectively.

[0014] The regulating mechanism comprises a second connecting tube, a leveler and a second adjusting screw. At least two levels are provided. The two levelers and the second adjusting screws are respectively connected to the second connecting tube.

[0015] The two levelers are connected to the second connecting pipe on the left and right sides; and the second adjusting screw is connected between the two levelers.

[0016] The second connecting pipe is made of an aluminum alloy square pipe.

[0017] The two levels are a horizontal level and a vertical level with scales. Beneficial Effects

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] according to Figure 1 and Figure 2 A PHC pile center detection device shown includes a pile circumferential fixing mechanism, an adjusting mechanism 4 and a plumb bob; the adjusting mechanism 4 is connected to the center position of the pile circumferential fixing mechanism and is vertically arranged with the pile circumferential fixing mechanism; the plumb bob is suspended at the free end of the adjusting mechanism 4.

[0028] When in use, the pile circumference fixing mechanism is connected to the pile at the junction of the pile and the pile shoe, and the axis of the adjustment mechanism 4 is adjusted to be parallel to the axis of the pile. Then, the plumb bob is hung on the free end of the adjustment mechanism 4 near the pile shoe side, and after the plumb bob is stable, a tape measure is used to measure the vertical distance from the center of the pile shoe to the plumb line. The smaller the vertical distance from the center of the pile shoe to the plumb line, the higher the accuracy of measuring the coincidence of the center of the pile shoe with the center of the pile.

[0029] The use of the utility model to detect the core of the PHC pipe pile is not only simple and convenient, but also has a low manufacturing cost.

[0030] Furthermore, the pile circumferential fixing mechanism includes multiple sections of first connecting tubes 2, hinged tubes 3 and first adjusting screws 1; adjacent first connecting tubes 2 are respectively hinged by hinged tubes 3 to form a straight-line and bendable integral structure; first adjusting screws 1 are respectively connected to the first connecting tubes 2 at both ends. Multiple sections of first connecting tubes 2 are hinged together by hinged tubes 3, so that the pile circumferential fixing mechanism can be conveniently matched with the outer periphery of PHC piles of different diameters, and the position of the first adjusting screw 1 on the pile is adjusted so that the axis of the adjusting mechanism 4 is parallel to the axis of the pile and then fixed on the pile. This technical solution makes the application range of the utility model wider.

[0031] Furthermore, the first connecting tube 2 is an aluminum alloy square tube; both ends of the first connecting tube 2 are symmetrically provided with hinge holes penetrating the upper and lower sides. The first connecting tube 2 is a square tube, so that the connection between the circumferential fixing mechanism of the pile and the pile is more stable, and the measured result is more accurate. The square tube is an aluminum alloy square tube, so that the overall weight is light, and it is more convenient to carry and store.

[0032] Furthermore, hinge holes are symmetrically formed at both ends of the hinged tube 3. The hinge holes are symmetrically arranged at both ends of the hinged tube 3, which not only makes the overall structure of the pipe pile circumferential fixing mechanism more symmetrical, but also facilitates the centering of the pipe pile circumferential fixing mechanism when it is used as a whole; at the same time, the stability of the connection between the pipe pile circumferential fixing mechanism as a whole and the pipe pile is relatively good.

[0033] Furthermore, the outer diameter of the articulated tube 3 is smaller than the inner diameter of the first connecting tube 2; the length of the articulated tube 3 is smaller than the length of the first connecting tube 2; and the ends of the articulated tube 3 are respectively placed in the first connecting tubes 2 on both sides. In actual use, the articulated tube 3 and the first connecting tube 2 adopt this technical solution, so that the circumferential fixing mechanism of the pile is better fitted with the pile. In specific application, the lengths of the articulated tube 3 and the first connecting tube 2 are 200-300mm and 400-500mm respectively, and the lengths of the articulated tube 3 and the first connecting tube 2 can be selected according to the actual diameter of the pile.

[0034] Furthermore, the adjustment mechanism 4 includes a second connecting tube 6 , a level 5 and a second adjusting screw 7 ; at least two levels 5 are provided; and the two levels 5 and the second adjusting screws 7 are respectively connected to the second connecting tube 6 .

[0035] Furthermore, the two levelers 5 are connected to the second connecting pipe 6, and the second adjusting screw 7 is connected between the two levelers 5. In a specific application, the second adjusting screw 7 can also be adjusted in position.

[0036] Furthermore, the two levels 5 are respectively a horizontal level and a vertical level with scales.

[0037] Furthermore, the second connecting pipe 6 is made of an aluminum alloy square pipe.

[0038] In actual use, the purpose of adjusting the adjustment mechanism 4 is achieved by adjusting the first adjustment screw 1 and the second adjustment screw 7. During the adjustment process, two levelers 5, namely the horizontal leveler and the vertical leveler, are used for observation, and a reasonable adjustment strategy is adopted to finally make the axis of the adjustment mechanism 4 horizontal and parallel to the central axis of the pile.

[0039] The second connecting tube 6 adopts the technical solution of an aluminum alloy square tube, so that during the whole measurement process, the stability of the adjustment mechanism 4 is relatively good, thereby ensuring the accuracy of the measurement.

[0040] In the absence of conflicts, technicians in this field can combine the relevant technical features in the above examples according to actual conditions to achieve corresponding technical effects. The specific combinations are not described here one by one.
