Description
Technical Field
[0001] The utility model relates to the technical field of pile foundation construction equipment, and specifically relates to a rain-proof device for pile welding during the pile planting process. Background Art
[0002] Welding and lengthening upper and lower precast pipe piles is a conventional operation during the pile planting process. If it rains, the construction has to stop, which affects the construction period. If welding is carried out in the rain, the welding quality and construction efficiency are likely to be affected.
[0003] In recent years, some rain-proof devices for pile welding during the pile planting process have emerged. Some are in the structure of sunshades, and some are in the structure of tents.
[0004] However, the above-mentioned existing rain-proof devices for pile welding during the pile planting process still have the following deficiencies: some structures are relatively complex. For example, the tent structure cannot be quickly installed and disassembled. Generally, they only have the functions of rain-proof and sun-shading, and do not have the function of preventing high-altitude falling objects. For example, large mud blocks sometimes fall off the upper pile of precast pipe piles, damaging the raincloth or hurting people.
[0005] The above-mentioned existing rain-proof devices for pile welding during the pile planting process also have a common deficiency: the rain-proof devices are detachably connected to the upper pile of the butt-jointed precast pipe piles. For each pair of upper and lower piles welded, the rain-proof device must be installed once, and after welding is completed, the rain-proof device must be disassembled once. Their installation and disassembly are relatively cumbersome, which relatively increases the labor intensity of operators and relatively reduces the construction efficiency. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is to provide a rain-proof device for pile welding during the pile planting process, which has the functions of rain-proof, is convenient and fast in installation and disassembly, and does not need to be installed and disassembled on the upper pile every time a pair of upper and lower piles are welded.
[0007] The technical solution of the utility model is to provide a rain-proof device for pile welding during the pile planting process, which includes two rigid plates for rain-proof connected to the two pressing pile cylinders on both sides of the static pile pressing device of the pile driver construction platform. The connection enables each rigid plate to be in a vertical state outside the pressing pile cylinder or in a horizontal state above the pressing pile cylinder; each rigid plate has a semi-circular hole or a C-shaped hole matching the shape of the precast pipe pile; there is a lock for fixing the two rigid plates to each other when they are in a horizontal state.
[0008] After adopting the above structure, the rain-proof device for pile welding during the pile planting process of the utility model has the following advantages:
[0009] When in use, manually turn the two rigid plates, such as the opaque steel plates described below, to a horizontal state above the pile pressing cylinder, i.e., above the weld, and buckle the lock to fix the two rigid plates to each other as an integral shielding plate to protect against rain or sun. The structure of this rainproof device is relatively simple. In particular, it is not necessary to install and disassemble this rainproof device on the upper pile every time a pair of upper and lower piles are welded. Instead, the two rigid plates for rain protection are permanently installed on the pile pressing cylinders on both sides of the static pile pressing device on the pile driving machine construction platform. When in use, manually rotate and close them and buckle them to the use state. After each weld is completed, manually unfasten and rotate them to separate to the vertical state. When not in use, the two rigid plates are in a vertical state and are located outside the pile pressing cylinders respectively, neither affecting pile pressing nor interfering with normal construction. Their installation to the use state and disassembly to the non-use state are both convenient and fast, relatively reducing the labor intensity of the operators and relatively improving the construction efficiency.
[0010] Further, there are two locks, which are respectively located at the connection of the two rigid plates on both sides of the pipe pile. After adopting the above structure, the locked connection after clamping is more firm and reliable, making the structure of the two rigid plates as an integral shielding plate more firm, stable and reliable.
[0011] Further, each lock includes a hanging ring seat fixed on one rigid plate, a hanging ring is hinged on the hanging ring seat, each lock also includes a hook fixed on the other rigid plate for the hanging ring to hang into to fix the two rigid plates, the opening of the hook is away from the hanging ring seat, and each lock also includes a structure for tightening or disengaging the hanging ring and the hook. After adopting the above structure, the buckling or unbuckling and disengaging of the lock are more convenient and fast, and the locked connection after clamping is more firm and reliable, making the structure of the two rigid plates as an integral shielding plate more firm, stable and reliable.
[0012] Further, the hanging ring is rectangular; one end of a lever is hinged to one end of the hanging ring seat close to the hook, a transverse rod of the rectangular hanging ring is movably sleeved in a through hole at the end of the lever away from the hook, and the free end of the lever away from the hook is a force application end for making the lever fit against the hanging ring seat and making the other transverse rod of the hanging ring tightly buckle on the inner wall of the hook when the other transverse rod of the hanging ring is hooked in the hook. After the structure for tightening or disengaging the hanging ring and the hook adopts the above specific structure, its tightening or unbuckling and disengaging operations are convenient, fast and the tightening is firm, stable and reliable, further ensuring the technical effect that the structure of the two rigid plates as an integral shielding plate is more firm, stable and reliable.
[0013] Further, there are two pile pressing cylinders on each side. A cross bar is fixed on the two pile pressing cylinders. One end of the cross bar is hinged to one end of a vertical bar, and the other end of the vertical bar is hinged to the outer edge of the bottom surface of a rigid plate. After adopting the above structure, by using the existing static pile pressing device with two pile pressing cylinders on each side, each rigid plate is connected to the pile pressing cylinders through its respective vertical bar and cross bar. Its rotation for closing or separating is convenient and smooth. When closed, the support is firm, stable and reliable, further ensuring the technical effect that the structure of the two rigid plates as an integral shielding plate is more firm, more stable and more reliable.
[0014] Further, there is a reinforcing strip on the outer edge of the bottom surface of the rigid plate. The pair of hinge ear plates of the hinged structure between the other end of the vertical bar and the bottom plate are fixed on the reinforcing strip. After adopting the above structure, the overall strength and firmness of the rigid plate are better. Further ensuring the technical effect that the structure of the two rigid plates as an integral shielding plate is more firm, more stable and more reliable.
[0015] Further, there is one or more push-pull handles on the outer side of the bottom surface of each rigid plate. After adopting the above structure, the operation of manually closing or separating the two rigid plates is more convenient, labor-saving, handy and fast.
[0016] Further, sealing half rings forming a complete sealing ring are fixed on the inner walls of the semicircular holes or U-shaped holes of each rigid plate. After adopting the above structure, after the two rigid plates are closed to form an integral shielding plate, the central hole of the rigid plate is liquid-sealed with the pipe pile, preventing rainwater from penetrating between the hole wall and the outer wall of the pipe pile, further ensuring the quality and efficiency of the welding of the upper and lower pipe pile welds.
[0017] Further, the rigid plate is a steel plate. After adopting the above structure, the steel plate is opaque, has stiffness and strength, overcoming the disadvantages of the existing rain-proof devices having only rain-proof function or only rain-proof and sun-shading functions, making the device have the function of preventing high-altitude falling objects. For example, even if large mud blocks fall off from the upper pile of the upper precast pipe pile from time to time, they will not damage the shielding plate, and it also prevents the phenomenon of high-altitude falling objects hurting people.

[0026] The specific embodiments of the present utility model will be further described below with reference to the accompanying drawings. It should be noted here that the description of these specific embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various specific embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown.
[0028] Generally, the pile pressing device on the pile driving machine construction platform in the prior art is a static pile pressing device 1. As shown in the figure, the static pile pressing device 1 includes a base 14. Two gantry frames 12 are fixed to the base 14, such as by welding. On each of the two gantry frames 12 on both sides, there are two pile pressing cylinders 11. The two pile pressing cylinders 11 are fixed, such as by using a flange 15 and multiple screws 16, to the top surface of the cross beam 121 of the respective gantry frame 12. The piston rods 111 of the respective pile pressing cylinders 11 extend downward through the vertical through holes in the cross beam 121 of the gantry frame 12. It is not difficult to understand that the pile holding box connected to the free end of the piston rod 111 and multiple horizontal pile holding cylinders provided on the pile holding box are omitted in the figure. The lower pile 132 of the precast pipe pile 13 to be extended is held by the horizontal pile holding cylinders of the pile holding box. The upper pile 131 to be butt-jointed is coaxially butted on the top of the lower pile 132. Both the upper pile 131 and the lower pile 132 are in a vertical state, and the connection between the upper pile 131 and the lower pile 132 is a weld 133. The above is the prior art.
[0029] The rainproof device of the present invention for the welding of pile splicing during the pile planting process, which can also be called the device for rainproof of pile splicing welding during the pile planting process. The rainproof device 2 includes two rigid plates 21 for rainproof, which are connected to the pile pressing cylinders 11 on both sides of the static pile pressing device 1 on the pile driving machine construction platform. The connection is such that Figure 5 as shown, each rigid plate 21 can be in a vertical state outside the pile pressing cylinder 11, or Figure 1 and Figure 2 as shown, in a horizontal state above the pile pressing cylinder 11 or above the weld 133, which is an articulated connection. Each rigid plate 21 has a semicircular hole 211 or a C-shaped hole that matches the outer shape of the precast pipe pile 13. It is not difficult to understand that the circular hole formed after the semicircular holes 211 are closed matches the circular precast pipe pile 13, and the square hole formed after the C-shaped holes are closed matches the square precast pipe pile. The rigid plate 21 is an opaque rigid plate, generally made of steel plate, and can also be made of hard plastic plate, wooden board, etc. It is not difficult to understand that the rainproof device 2 for the welding of pile splicing during the pile planting process also has the functions of sunshade and preventing high-altitude falling objects.
[0030] There are latches 22 on the two rigid plates 21 for fixing the two rigid plates 21 to each other when in a horizontal state.
[0031] Preferably, there are two latches 22, which are respectively located at the connection of the two rigid plates 21 on both sides of the precast pipe pile 13. It can also be understood as the connection of the two rigid plates 21 respectively located on both sides of the circular hole formed after the two semicircular holes 211 are closed.
[0032] Each latch 22 preferably includes a hanging ring seat 221 fixed, such as by welding or screwing with multiple screws, onto a rigid plate 21. A hanging ring 222 is hinged to the hanging ring seat 221. Each latch 22 further includes a hook 223 fixed, such as by welding or screwing with multiple screws, onto another rigid plate 21, and into which the hanging ring 222 is hooked to fix the two rigid plates 21. The opening of the hook 223 faces away from the hanging ring seat 221. Each latch 22 also includes a structure for fastening or disengaging the hanging ring 222 with the hook 223. It is not difficult to understand that the hanging ring 222 can be rectangular. As Figure 3 shown, the structure for fastening or disengaging the hanging ring 222 with the hook 223 can be that one end of a lever 224 is hinged to one end of the hanging ring seat 221 close to the hook 223. A transverse rod 2221 of the rectangular hanging ring is movably sleeved in a through hole 2241 or a transverse through hole away from the hook 223 on the lever 224. The free end of the lever 224 away from the hook 223 is a force - applying end 2242 that, when the other transverse rod 2222 of the hanging ring 222 is hooked in the hook 223, makes the lever 224 fit against the hanging ring seat 221 and makes the other transverse rod 2222 of the hanging ring 222 fastened against the inner wall of the hook 223. The lever 224 can rotate 180° around the axis of the hinge shaft 225, so that the hanging ring 222 falls into the opening of the hook 223 and is turned 180° in the reverse direction to fasten the hanging ring 222 with the hook 223, or in the fastened state, rotate 180° around the axis of the hinge shaft 225 to disengage the hanging ring 222 from the hook 223 to separate the two rigid plates 21, such as two steel plates.
[0033] The structure for fastening or disengaging the hanging ring with the hook can also be that a transverse rod of the rectangular hanging ring is slidably fitted in a longitudinal long through hole of the hanging ring seat. A cam - type pressing block is hinged to the hanging ring seat. When the other transverse rod of the hanging ring is hooked in the hook, rotate the cam - type pressing block to press a transverse rod of the hanging ring away from the hook direction to make the other transverse rod fastened against the inner wall of the hook, and reverse operation can disengage it.
[0034] As Figure 1 、 Figure 2 and Figure 5 shown, there can be two pile - pressing cylinders 11 on each side. A cross bar 23 is fixed, such as by a hoop 210 and multiple bolt nuts 212, onto the two pile - pressing cylinders 11. One end of the cross bar 23 is hinged to one end of a vertical rod 24, and the other end of the vertical rod 24 is hinged to the outer edge of the bottom surface of a rigid plate 21.
[0035] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, there is a reinforcing strip 25 along the outer edge of the bottom surface of the rigid plate 21, such as a strip-shaped steel plate welded to the bottom surface of each steel plate. The specific structure of the hinge described above can be: one end of the vertical rod 24 has a steel sleeve 241, and the steel sleeve 241 is rotatably sleeved on the cross bar 23; a pair of ear plates 26 are welded on the reinforcing strip 25 such as the strip-shaped steel plate, and the other end of the vertical rod 24 is hinged to the pair of ear plates 26. For example, the other end of the vertical rod 24 is a flat connecting block 242, the connecting block 242 has a hinge pin through hole, and the pair of ear plates 26 have a pair of hinge pin through holes coaxial with the hinge pin through hole on the connecting block 242. A hinge pin 27 passes through the three hinge pin through holes, one end of the hinge pin 27 can be axially limited by a shoulder or a large head, and the other end can be axially limited by a split pin or a nut.
[0036] Of course, there can also be one pressing pile oil cylinder on each side. The top end of one pressing pile oil cylinder can be fixed with a pair of ear plates, and the upper and lower ends of the vertical rod can be hinged to their respective pairs of ear plates through their respective hinge pins.
[0037] There is one or more push-pull handles 28 on the outer side of the bottom surface of each rigid plate 21. Such as Figure 1 and Figure 2 As shown, two push-pull handles 28 are welded on the outer side of the bottom surface of each rigid plate 21 such as a steel plate. Both of the two push-pull handles 28 can be welded on the reinforcing strip 25 such as the strip-shaped steel plate.
[0038] Sealing half rings 29 forming a complete sealing ring are fixed on the inner walls of the semi-circular holes 211 or U-shaped holes of each rigid plate 21, such as a rubber sealing ring or rubber seal formed by rubber sealing half rings adhesively bonded or screwed with countersunk screws on the inner walls of the semi-circular holes 211 or U-shaped holes.
[0039] Except for the description of the lock 22 involving two rigid plates 21, the above mainly describes one of the two rigid plates 21 and its accessory structures such as the semi-circular holes 211, accessories such as the reinforcing strip 25, the push-pull handles 28, etc. and their connection structures with their respective pressing pile oil cylinders 11. It is not difficult to understand that except for the different structures of the lock 22 on their respective rigid plates 21, the remaining structures on the two rigid plates 21 are the same and symmetrically arranged.
[0040] Hinging, pivoting and rotational connection can be used interchangeably. The hinge shaft 225 and the hinge pin 27 can be used interchangeably.
