Description

Technical Field

[0001] This application relates to the field of cement mixing pile technology, and more specifically, to a cement mixing pile construction positioning device. Background Technology

[0002] When constructing cement mixing piles, the construction points must first be marked at the construction site, and the mixing rod must be accurately positioned and installed above the construction points. Accurate positioning ensures that the axis of the mixing rod coincides with the construction point. Currently, the axis of the mixing rod is positioned using a C-shaped connecting rod and a connecting sleeve with the same dimensions, with a laser locator installed below the mixing rod. The laser spot of the locator is used as a reference to adjust the axis of the mixing rod to coincide with the construction point. However, in actual use, the mixing rod will frequently rub against the concrete during construction, causing scratches and pits on its outer wall. When the connecting sleeve and C-shaped connecting rod are installed on the outer wall of the mixing rod, the laser locator will shift and tilt, and its axis will not coincide with the axis of the mixing rod, affecting the accuracy of the mixing rod positioning.

[0003] Therefore, it is necessary for the inventors to design a new cement mixing pile construction positioning device to overcome the above problems. Summary of the Invention

[0004] The main objective of this application is to provide a cement mixing pile construction positioning device to solve the problem of low positioning accuracy of cement mixing rods in related technologies.

[0005] To achieve the above objectives, this application provides a cement mixing pile construction positioning device. The laser locator is detachably connected to a double-opening connecting sleeve on its outer side. An arc-shaped rotating connecting ring is fixedly connected to the outer wall of the double-opening connecting sleeve. An inner arc groove connecting ring is rotatably connected to the outer wall of the arc-shaped rotating connecting ring. Horizontal adjusting rods are provided on both sides of the inner arc groove connecting ring. An extension connecting rod is threaded to the outer wall of one of the horizontal adjusting rods. A lateral adjusting rod is fixedly connected between the two horizontal adjusting rods. The lateral adjusting rod is slidably connected to the inner arc groove connecting ring. A plumb line cone is detachably connected to the bottom of the double-opening connecting sleeve.

[0006] Optionally, the bottom end of the double-opening connecting sleeve is fixedly connected to two symmetrically distributed flip-up connecting rods, and the top end of the vertical cone is fixedly connected to a "Y"-shaped connecting line, which is hung inside the flip-up connecting rods.

[0007] Optionally, a spacer support plate is fixedly connected to the inner wall of the double-opening connecting sleeve, and a magnetic positioning plate is fixedly connected to the top of the spacer support plate. The magnetic positioning plate is magnetically connected to the laser positioner.

[0008] Optionally, each of the two extension connecting rods is fixedly connected to a snap-fit ​​connecting arc plate at its top end, and the two snap-fit ​​connecting arc plates are fixedly connected by bolts.

[0009] Optionally, a polytetrafluoroethylene coating is provided between the arc-shaped rotating connecting ring and the inner arc groove connecting ring.

[0010] The cement mixing pile construction positioning device provided by this utility model has the following advantages compared with the prior art:

[0011] The laser positioner is positioned using a double-opening connecting sleeve. The laser positioner is suspended and positioned by the cooperation of the arc-shaped rotating connecting ring, the inner arc groove connecting ring, and the vertical cone. The position of the double-opening connecting sleeve can be adjusted by the horizontal adjustment rod, the extension connecting rod, and the lateral adjustment rod, which can ignore the connection error between the locking connecting arc plate and the stirring rod, adjust the axis of the laser positioner and the stirring rod, improve the accuracy of the laser positioner installation position, and position the stirring rod more accurately.

[0024] like Figs. 1 to 4As shown, a cement mixing pile construction positioning device includes a laser locator 1 with a detachable double-opening connecting sleeve 2 on its outer side. An arc-shaped rotating connecting ring 21 is fixedly connected to the outer wall of the double-opening connecting sleeve 2. An inner arc groove connecting ring 3 is rotatably connected to the outer wall of the arc-shaped rotating connecting ring 21. Horizontal adjusting rods 31 are provided on both sides of the inner arc groove connecting ring 3. One of the horizontal adjusting rods 31 has an extension connecting rod 32 threadedly connected to its outer wall. A lateral adjusting rod 33 is fixedly connected between the two horizontal adjusting rods 31. The lateral adjusting rod 33 is slidably connected to the inner arc groove connecting ring 3. A plumb bob 4 is detachably connected to the bottom of the double-opening connecting sleeve 2.

[0025] Specifically, the operator installs the snap-fit ​​connecting arc plate 34 on the outer wall of the stirring rod. Using the extension connecting rod 32, the inner arc groove connecting ring 3, the horizontal adjusting rod 31, the lateral adjusting rod 33, and the double-opening connecting sleeve 2 are extended to the bottom of the stirring rod. The operator then installs a plumb bob 4 below the double-opening connecting sleeve 2, using the plumb bob 4 to suspend and position the double-opening connecting sleeve 2, ensuring it is vertical. The arc-shaped rotating connecting ring 21, in conjunction with the inner arc groove connecting ring 3, allows the double-opening connecting sleeve 2 to rotate freely. Subsequently, the operator inserts the laser positioner 1 into the opening at the top of the double-opening connecting sleeve 2, using the double-opening connecting sleeve 2 to position the laser positioner 1. The operator then uses the horizontal adjusting rod 31, the extension connecting rod 32, and the lateral adjusting rod 33 to... 3. Adjust the position of the double-opening connecting sleeve 2 to align the laser spot of the laser positioner 1 with the center of the stirring rod. Then, the operator inserts the laser positioner 1 into the bottom opening of the double-opening connecting sleeve 2 and removes the plumb bob 4. Measure the distance between the laser spot of the laser positioner 1 and the pre-marked construction point. The operator adjusts the position of the stirring rod according to the measured distance until the laser spot of the laser positioner 1 coincides with the pre-marked construction point. During this process, the device can ignore the connection error between the locking connecting arc plate 34 and the stirring rod, and adjust the axis of the laser positioner 1 and the stirring rod to align. Unevenness caused by damage to the outer wall of the stirring rod will not affect the positioning accuracy of the double-opening connecting sleeve 2, thereby improving the accuracy of the laser positioner 1 installation position and more accurately positioning the stirring rod.

[0026] The bottom end of the double-opening connecting sleeve 2 is fixedly connected to two symmetrically distributed rotating connecting rods 22, and the top end of the plumb line cone 4 is fixedly connected to a "Y"-shaped connecting line 41, which is hung inside the rotating connecting rods 22. Specifically, by setting the rotating connecting rods 22 and the "Y"-shaped connecting line 41, the double-opening connecting sleeve 2 and the plumb line cone 4 can be detachably connected, allowing workers to easily install and remove the plumb line cone 4 from under the double-opening connecting sleeve 2. In actual production, a lubricating coating is applied to the outer wall of the rotating connecting rods 22 so that the forked line at the top of the "Y"-shaped connecting line 41 can slide smoothly to the bottom of the rotating connecting rods 22, so that the forked line at the top of the "Y"-shaped connecting line 41 can be symmetrically distributed, and so that the axis of the plumb line cone 4 can coincide with the central axis of the double-opening connecting sleeve 2.

[0027] A spacer support plate 23 is fixedly connected to the inner wall of the double-opening connecting sleeve 2. A magnetic positioning plate 24 is fixedly connected to the top of the spacer support plate 23, and the magnetic positioning plate 24 is magnetically connected to the laser positioner 1. Specifically, by setting the spacer support plate 23, the internal space of the double-opening connecting sleeve 2 can be separated, and the laser positioner 1 can be supported, so that the laser positioner 1 can be stably installed in the top opening of the double-opening connecting sleeve 2. The laser positioner 1 has an iron shell, so that the laser positioner 1 can be magnetically connected to the magnetic positioning plate 24. By setting the magnetic positioning plate 24, it is easy to position the laser positioner 1 and prevent the laser positioner 1 from falling under the action of gravity.

[0028] Both of the extended connecting rods 32 are fixedly connected to their top ends with engaging connecting arc plates 34, which are then fixedly connected by bolts. Specifically, by setting the engaging connecting arc plates 34, the device can be installed on the outside of the stirring rod. The engaging connecting arc plates 34 only serve a fixing and supporting function and will not be affected by damage from the unevenness of the outer wall of the stirring rod.

[0029] A polytetrafluoroethylene (PTFE) coating is provided between the arc-shaped rotating connecting ring 21 and the inner arc groove connecting ring 3. Specifically, by providing the PTFE coating, the friction between the arc-shaped rotating connecting ring 21 and the inner arc groove connecting ring 3 can be reduced, thereby further improving the positioning accuracy of the double-opening connecting sleeve 2.

[0030] The working principle and usage process of this utility model are as follows: The operator installs the snap-fit ​​connecting arc plate 34 on the outer wall of the stirring rod. Using the extension connecting rod 32, the inner arc groove connecting ring 3, the horizontal adjusting rod 31, the lateral adjusting rod 33, and the double-opening connecting sleeve 2 are extended to the bottom of the stirring rod. The operator then installs a plumb bob 4 below the double-opening connecting sleeve 2, using the plumb bob 4 to suspend and position the double-opening connecting sleeve 2, ensuring it is in a vertical position. The arc-shaped rotating connecting ring 21, in conjunction with the inner arc groove connecting ring 3, allows the double-opening connecting sleeve 2 to rotate freely. Subsequently, the operator inserts the laser positioner 1 into the double-opening... The laser positioner 1 is positioned in the opening at the top of the connecting sleeve 2. The operator adjusts the position of the double-opening connecting sleeve 2 using the horizontal adjusting rod 31, the extension connecting rod 32, and the lateral adjusting rod 33 to adjust the spot of the laser positioner 1 to the center of the stirring rod. Then, the operator inserts the laser positioner 1 into the bottom opening of the double-opening connecting sleeve 2 and removes the plumb bob 4. The distance between the spot of the laser positioner 1 and the pre-marked construction point is measured. The operator adjusts the position of the stirring rod according to the measured distance until the spot of the laser positioner 1 coincides with the pre-marked construction point.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
