Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction tools, in particular to a pipe pile laying device. Background Art
[0002] PHC (Pre-stressed High-strength Concrete) pipe pile is a hollow cylindrical concrete precast component made by pre-stressed centrifugal forming process. It has been widely used due to its high single pile bearing capacity and low engineering cost.
[0003] At present, most of the surveying and laying out in the construction process uses GPS (Global Positioning System) or total station. This method can measure and lay out points more conveniently, but it cannot quickly measure and lay out the construction position of the outer contour of the pile. When the PHC pile is directly pressed in without a top support plate, since the cross-section of the PHC pile is annular, it is impossible to accurately press in according to the measured center point. Conventionally, when the PHC pile is constructed without a top support plate, an instrument is often used to measure the center point and insert a short stick. Then, the end fixing frame of the tape measure is inserted into the short stick, and the outer radius distance of the PHC pile is measured with the center point as the center of the circle. The outer contour position of the PHC pile is determined by spreading white lime around the center of the circle. Although this method can measure and lay out the outer contour line of the PHC pile, it is less efficient. Utility Model Content

[0029] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a pipe pile laying device, including an outer sleeve 100, a positioning rod 200, a tray 300 and a discharge plate 400, wherein the outer sleeve 100 is a hollow cylindrical structure with two ends open, the positioning rod 200 includes a rod section 210 axially movably inserted into the outer sleeve 100 and a positioning tip 221 formed at the end of the rod section 210; the tray 300 includes a disk body 310 and an annular baffle 320 fixedly arranged on the disk body 310, and the annular baffle 320 A stacking area 330 is constructed together with the disk body 310. The disk body 310 is fixedly connected to the outer periphery of the positioning rod 200 and is located between the outer sleeve 100 and the positioning tip 221. The disk body 310 is provided with a plurality of unloading holes 311 arranged in a ring shape, and the outer diameter of the ring is the same as the outer diameter of the pipe pile; the unloading plate 400 is fixedly connected to one end of the outer sleeve 100 close to the positioning tip 221, the unloading plate 400 is located in the stacking area 330, and the unloading plate 400 covers the unloading holes 311 along the axial direction.
[0031] When it is necessary to lay out the pipe piles, first, use a measuring instrument to measure and lay out the center point of the pipe piles; secondly, align the positioning tip 221 of the positioning rod 200 with the center point and press it into the soil layer; then, fill the stacking area 330 of the tray 300 with lime for marking the lines, at which time the lime covers the unloading plate 400; then, lift the outer sleeve 100 so that the unloading plate 400 moves upward to increase the distance between the unloading plate 400 and the tray body 310 of the tray 300, so that the lime in the stacking area 330 can enter the area between the unloading plate 400 and the tray body 310, thereby flowing to the ground through the unloading port; finally, take the pipe pile laying device out from the ground, so as to obtain a positioning ring on the ground with the same outer diameter as the pipe pile.
[0032] The pipe pile laying device can quickly form a positioning ring consistent with the outer contour line of the pipe pile from the center point measured by the measuring instrument, with high efficiency, so that the construction laying speed is greatly improved in the working environment where a large number of pipe piles are used for construction. In addition, compared with the manual ash spreading operation mode, the material is discharged through the discharge hole 311 of the tray 300, the accuracy is improved, and there is no need for manual bending operation, which effectively reduces the fatigue of the staff during the operation.
[0033] In addition, the pipe pile laying device is only a mechanical laying structure, and does not require power equipment or other energy equipment for power supply during use. It not only saves energy and reduces emissions, but also can well meet the construction environment such as the field where there is no power condition. It has high versatility and a wide range of uses.
[0034] It should be noted that, in this embodiment, the pipe pile can be a PHC pipe pile.
[0035] It should also be noted that, in this embodiment, “axial direction” refers to the length direction of the positioning rod 200 .
[0036] Please continue to refer to Figure 1 , and combined with Figure 3 In this embodiment, the positioning rod 200 may further include a handle 230 . Specifically, the handle 230 is fixedly disposed at the end of the rod body section 210 away from the positioning tip 221 .
[0037] When the pipe pile laying device is needed for laying out, the staff can hold the handle 230 to move the pipe pile laying device. The setting of the handle 230 provides a force application point for the staff, which is convenient for carrying the pipe pile laying device.
[0038] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the handle 230 may be a long plate-shaped structure, and a wave surface is provided on the lower surface of the handle 230. This arrangement can improve the convenience of gripping for the staff.
[0039] It should be noted that, in this embodiment, the handle 230 can be installed after the rod section 210 passes through the outer sleeve 100 .
[0040] In this embodiment, the handle 230 can be made of a flexible material.
[0041] Please continue to refer to Figure 1 , and combined with Figure 4 In this embodiment, the rod body section 210 is a tapered section 220 at the end away from the handle 230 , wherein the apex of the tapered section 220 forms a positioning tip 221 .
[0042] This form of forming the positioning tip 221 by using the vertex of the conical section 220 realizes the structural transition from the rod body section 210 to the positioning tip 221 , ensures the structural strength of the positioning tip 221 , and reduces the risk of the positioning tip 221 breaking.
[0043] It should be noted that the tapered section 220 may be a conical structure or a pyramidal structure.
[0044] Please continue to refer to Figure 1 and Figure 3In this embodiment, the pipe pile laying device may further include a rebound structure 500 , wherein the rebound structure 500 is configured to make the outer sleeve 100 always have a tendency to move toward the disc body 310 .
[0045] During use of the pipe pile laying device, after the outer sleeve 100 is lifted to make the discharge plate 400 move upward to lay out the wire, under the action of the rebound structure 500, the outer sleeve 100 will move back to the disk body 310 to wait for the next laying out operation.
[0046] The arrangement of the above-mentioned rebound structure 500 can realize the automatic reset of the outer cover 100, and further improve the wire-releasing efficiency.
[0047] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the rebound structure 500 includes a first flange 510, a second flange 520 and an elastic element 530, wherein the first flange 510 is fixedly arranged on the outer periphery of the rod body segment 210, the second flange 520 is fixedly arranged on the outer periphery of the sleeve 100, the elastic element 530 is located between the first flange 510 and the second flange 520, and the elastic expansion and contraction direction of the elastic element 530 is along the axial direction.
[0048] During use of the pipe pile laying device, when the outer sleeve 100 is lifted to make the discharge plate 400 move upward, the elastic element 530 is compressed to generate elastic potential energy; after the lime in the stacking area 330 flows out to the ground through the discharge hole 311, that is, after the laying operation is completed, when the staff releases the outer sleeve 100, the outer sleeve 100 will move toward the disk body 310 under the action of the above-mentioned elastic potential energy, and reset to wait for the next lifting and laying operation.
[0049] By setting the elastic expansion and contraction direction of the elastic element 530 to be along the axial direction, after the jacket 100 is loosened, the elastic potential energy generated by the elastic element 530 can directly act on the jacket 100 to drive the jacket 100 to move downward, thereby ensuring the reliability and timeliness of the resetting of the jacket 100.
[0050] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the elastic element 530 may include a coil spring, wherein the coil spring is sleeved on the rod body segment 210 , and one end of the coil spring abuts against the first flange 510 , and the other end of the coil spring abuts against the second flange 520 .
[0051] This arrangement of the elastic element 530, on the one hand, can utilize the rod body segment 210 to guide the expansion and contraction process of the elastic element 530 to a certain extent, thereby preventing the elastic element 530 from twisting or bending. On the other hand, the rod body segment 210 can also be utilized to limit the elastic element 530, thereby preventing the elastic element 530 from falling off between the first flange 510 and the second flange 520.
[0052] It should be noted that, when assembling the pipe pile laying-out device, the elastic element 530 and the first flange 510 can also be assembled after the rod section 210 passes through the outer sleeve 100 .
[0053] Please continue to refer to Figure 1 and Figure 3 , the outer diameter of the first flange 510 is smaller than the outer diameter of the second flange 520 .
[0054] By setting the outer diameter of the first flange 510 to be smaller than the outer diameter of the second flange 520 , the second flange 520 is radially more protruding than the first flange 510 , making it easier for workers to apply a lifting force to the outer sleeve 100 through the second flange 520 .
[0055] In this embodiment, the outer sleeve 100, the positioning rod 200, the tray 300, the unloading plate 400, the first flange 510 and the second flange 520 are all made of aluminum alloy. In other words, in the pipe pile laying device, except for the elastic element 530, the rest of the materials can be set to aluminum alloy.
[0056] The setting of the above-mentioned materials can, on the one hand, reduce the weight of the pipe pile laying-out device, making the pipe pile laying-out device lighter and easier to move and use; on the other hand, it can also ensure the strength of the pipe pile laying-out device, improve its durability, and thus extend its service life.
[0057] In this embodiment, lubricating grease is filled between the rod section 210 and the outer sleeve 100 .
[0058] By filling lubricating grease between the rod segment 210 and the outer sleeve 100, the friction resistance between the rod segment 210 and the outer sleeve 100 can be reduced, and the smoothness of the relative movement of the rod segment 210 and the outer sleeve 100 along the axial direction can be improved, thereby further improving the wire release efficiency.
[0059] Please continue to refer to Figure 2 In this embodiment, a plurality of discharge holes 311 are arranged at equal intervals along the circumference of the rod body section 210 .
[0060] By arranging the plurality of discharge holes 311 at equal intervals along the circumference of the rod body section 210 , the lime in the stacking area 330 can form a relatively regular circular ring mark on the ground after flowing out of the discharge holes 311 , thereby facilitating identification by the staff.
[0061] Please continue to refer to Figure 1 In this embodiment, the total length L of the pipe pile laying device is 1200 mm. This configuration makes the pipe pile laying device more ergonomically designed during use, and basically does not require workers to squat or bend over to operate, further reducing the fatigue of workers during operation.
