Abstract
Description
Technical Field
[0001] The utility model relates to a construction auxiliary device, in particular to a positioner used for prefabricated pile construction. Background Art
[0002] At present, on construction sites, during the sinking operation of precast piles, special casings are generally set on the pile frame or column of the pile driver to ensure the vertical sinking of the precast piles. The casings are fixedly installed on the pile frame or column of the pile driver. Therefore, each time for the construction of precast piles of different specifications and shapes (mainly circular precast piles and square precast piles), the casings need to be replaced as a whole, which is very inconvenient and has low work efficiency. Another more important point is that during the construction process, since each precast pile generally has a height of about half a meter exposed to the ground after sinking into place, plus the height of the casing itself, the lifting height of the next precast pile must be at least greater than the height above the casing. In this way, the lifting height of the precast pile will be higher, affecting construction safety. Summary of the invention
[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a precast pile construction operation positioner that can quickly adapt to the construction of precast piles of different specifications and shapes, reduce labor intensity and improve work efficiency, while reducing the lifting height of the precast piles during the construction process to ensure construction safety.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0005] The precast pile construction positioner is characterized in that it includes a fixed connecting frame, on which a left movable arm and a right movable arm are provided, the left movable arm and the right movable arm are pushed by a hydraulic cylinder on the fixed connecting frame to move closer to or farther away from each other, the front end of the left movable arm is detachably connected with a left positioning chuck, the front end of the right movable arm is detachably connected with a right positioning chuck, and the left and right positioning chucks are opposite to each other; when used for positioning in the construction of circular precast piles, the left and right positioning chucks have an arc-shaped positioning working surface, and when used for positioning in the construction of square precast piles, the left and right positioning chucks have a square positioning working surface.
[0006] The left movable arm and the right movable arm are swingably arranged on the fixed connecting frame. The left movable arm is pushed alone by the left hydraulic cylinder, and the right movable arm is pushed alone by the right hydraulic cylinder. The left and right hydraulic cylinders are installed on the fixed connecting frame.
[0007] When the positioning chuck has a square positioning working surface, the positioning chuck is composed of front and rear halves that are independent of each other.
[0008] The precast pile construction locator of the above technical solution can be installed at a very low height (less than half a meter, and the fixed connection frame of the precast pile locator is welded and fixed to the pile frame of the pile driver during installation) because the left and right positioning chucks are designed to be movable and open, so the height of the precast pile locator can be very low (less than half a meter, and the fixed connection frame of the precast pile locator is welded and fixed to the pile frame of the pile driver during installation), so that the lifting height of the next precast pile during the construction process only needs to be greater than the height of the previous precast pile exposed to the ground, thereby reducing the lifting height of the precast pile during the construction process and ensuring construction safety. In addition, since the left and right positioning chucks and the fixed connection frame respectively adopt a detachable connection structure, by quickly replacing the positioning chucks with arc-shaped positioning working surfaces of different curvatures and square positioning working surfaces of different sizes, it can quickly adapt to the construction of precast piles of different specifications and shapes, reduce labor intensity and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The utility model has the following drawings:
[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0011] As shown in the figure, the prefabricated pile construction positioner of the utility model includes a fixed connecting frame 1, which is used for fixedly welding and connecting with the pile frame of the pile driver. A left movable arm 10 and a right movable arm 5 are provided on the fixed connecting frame 1. The left movable arm 10 is swingably arranged on the fixed connecting frame 1 through a pin shaft 11, and the right movable arm 5 is swingably arranged on the fixed connecting frame 1 through a pin shaft 4. The swing of the left movable arm 10 is driven solely by the left hydraulic cylinder 2, and the swing of the right movable arm 5 is driven solely by the right hydraulic cylinder 3. The left hydraulic cylinder 2 and the right hydraulic cylinder 3 are installed on the fixed connecting frame. The front end of the left movable arm 10 is detachably connected to the left positioning clamp 8 by a bolt 9, and the front end of the right movable arm 5 is detachably connected to the right positioning clamp 7 by a bolt 6. The left positioning clamp 8 and the right positioning clamp 7 are opposite to each other; when used for positioning in the construction of circular precast piles, the left and right positioning clamps have an arc-shaped positioning working surface 81, and when used for positioning in the construction of square precast piles, the left and right positioning clamps have a square positioning working surface 71. Figure 1 In the figure, the left positioning chuck 8 has an arc-shaped positioning working surface 81, and the right positioning chuck 7 has a square positioning working surface 71. The right positioning chuck 7 with the square positioning working surface 71 is composed of front and rear halves that are independent of each other.
[0012] The above-mentioned precast pile construction locator, during the sinking operation of the precast pile, the left and right positioning clamps will approach each other, close and hold the precast pile under construction to ensure the vertical sinking of the precast pile. When the above-mentioned precast pile sinks into place, the left and right positioning clamps move away from each other, and the crane lifts the next precast pile to the top of the above-mentioned precast pile at a very small lifting height, and then the left and right positioning clamps approach each other again, close and hold the next precast pile, and then the sinking construction operation of the next precast pile can be carried out, and this cycle is repeated.
