Description

Technical Field

[0001] This utility model relates to the field of welding construction technology, specifically to a detachable and retractable windproof device for pile welding construction. Background Technology

[0002] The environment near water is generally more complex. Because air flows faster and friction is lower over water, air flows more smoothly, and wind speed increases. In addition, topographical factors also play a role. Riverbanks or seashores are usually flat and have no tall obstacles to block air flow, allowing air to move more freely and thus creating strong winds.

[0003] During the welding process of precast pipe piles, especially in open-air environments, high wind speeds can significantly impact welding quality. Welding must be prohibited when wind speeds are too high. Failure to take measures to block the wind and welding slag can lead to sparks flying, causing fires and serious quality problems.

[0004] To address these issues, we offer a detachable and retractable windproof device for pile welding construction. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a detachable and retractable windproof device for pile welding construction, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A removable and retractable windproof device for pile welding construction, including:

[0008] The vertical support main beam has an installation interface on its side, a pin is installed at the bottom, and a vertical shaft and a rotating wind vane are installed at the top.

[0009] Single-frame support keel, the single-frame support keel is bent and the inside is installed with fireproof and flame-retardant cloth;

[0010] For prestressed pipe piles, at least two sets of support keels are set for each frame, with one end connected to the installation interface of the vertical support main beam; the other end is located on the leeward side of the rotating wind vane.

[0011] The vertical support main beam and two sets of single-frame brackets are used to surround the prestressed pipe piles in a non-closed installation.

[0012] In a further technical solution, the vertical support beam is a triangular prism, and installation interfaces are installed on the adjacent two sides.

[0013] In a further technical solution, the insertion rod includes a rod body, with a spiked plug at the bottom of the rod body and a limit ring integrally formed on the rod body.

[0014] In a further technical solution, the vertical axis is detachably connected to the vertical support beam, and a mounting cavity is provided at the top. A connecting bearing is installed in the mounting cavity, the outer ring of the connecting bearing is fixedly connected to the inner wall of the mounting cavity, and the inner ring of the connecting bearing is fixedly connected to the rotating wind vane; the rotating wind vane is adapted to rotate relative to the vertical axis.

[0015] A limit ring is integrally installed on the outside of the vertical axis.

[0016] In a further technical solution, threaded holes are provided at both the upper and lower ends of the vertical support beam, and are respectively threaded to the rod body and the vertical shaft.

[0017] In a further technical solution, at least two sets of installation interfaces are provided on each side of the vertical support main beam;

[0018] Each set of installation interfaces includes an upper position plate and a lower position plate, and a positioning hole is provided between the upper position plate and the lower position plate; a connecting plate is provided at the end of a single bracket keel, and a mounting hole adapted to the positioning hole is provided on the connecting plate. The connecting plate is suitable for installation between the upper position plate and the lower position plate and is threadedly connected to a locking rod that passes through the mounting hole.

[0019] In a further technical solution, a single support keel includes two sets of frame plates; adjacent frame plates are hinged together.

[0020] In a further technical solution, the frame plate is C-shaped; a second connecting plate is fixedly installed at the open end of the frame plate, and an installation interface is provided on the frame plate; the second connecting plate and the installation interface are connected by a locking rod.

[0021] In a further technical solution, a plug is installed on the frame plate, and a pin rod is detachably installed inside the plug.

[0026] After the device is assembled, it is covered with fire-retardant cloth, and a rotating anemometer is inserted into the upper end of the vertical support beam to determine the wind direction. The position of the windproof device is then adjusted so that the opening faces the leeward side. Welding operations are carried out inside the windproof device, providing a good environment free from wind and welding slag splashes. This ensures both work quality and safety.

[0027] Compared with existing technologies, it has the following advantages:

[0028] After assembly, this invention covers the device with a fire-retardant cloth and inserts a wind gauge into the upper surface of the vertical support beam to determine the wind direction. The position of the windproof device is then adjusted so that the opening faces the leeward side. Welding operations are carried out inside the windproof device, providing excellent wind protection and preventing welding slag from splashing. This ensures both work quality and safety. The device is safe and stable, can be flexibly folded for storage, is easy to install and disassemble, can be reused continuously, and has a simple structure that is easy to maintain.

[0029] This utility model uses a track plate to achieve the sliding connection of the sliding plate, and enables the sliding installation of the fireproof and flame-retardant cloth while naturally preventing the fireproof and flame-retardant cloth from detaching from the frame plate, thus enabling the detachable installation of the fireproof and flame-retardant cloth.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1

[0050] Please see Figure 1-6 This utility model provides a technical solution for a detachable and retractable windproof device for pile welding construction, comprising:

[0051] The vertical support main beam 1 has an installation interface 2 on its side, a pin rod 3 is installed at the bottom, and a vertical shaft 4 and a rotating wind vane 5 are installed at the top.

[0052] The single frame keel 6 is bent and has fireproof and flame-retardant cloth 7 installed inside.

[0053] The prestressed pipe pile 8 has at least two sets of single-frame support keels 6, one end of which is connected to the installation interface 2 of the vertical support main beam 1; the other end is located on the leeward side of the rotating wind vane 5. Here, the line connecting the midpoint of the vertical support main beam and the midpoint of the end edge of the single-frame support keel 6 furthest from the vertical support main beam is in the same direction as the wind. The vertical support main beam is at the beginning, and the end edge of the single-frame support keel 6 furthest from the vertical support main beam is the end. This ensures that the wind blows towards the vertical support main beam first, thus allowing it to withstand greater wind force. The two sets of single-frame support keels 6 are not closed openings, facilitating personnel access. Each single-frame support keel 6 includes two sets of frame plates 63; adjacent frame plates 63 are hinged together.

[0054] The vertical support main beam 1 and two sets of single-frame brackets 6 are used to surround the prestressed pipe pile 8 and are installed in a non-closed manner. The vertical support main beam 1 is triangular prism-shaped, and installation interfaces 2 are installed on the sides of the adjacent two sides.

[0055] like Figure 6 As shown, the insert rod 3 includes a rod body 31, with a spiked plug 32 at the bottom of the rod body 31, and a limit ring 33 integrally provided on the rod body 31.

[0056] like Figure 4 As shown, the vertical shaft 4 is detachably connected to the vertical support beam 1, and has an installation cavity at the top. A connecting bearing 41 is installed in the installation cavity. The outer ring of the connecting bearing 41 is fixedly connected to the inner wall of the installation cavity, and the inner ring of the connecting bearing 41 is fixedly connected to the rotating wind vane 5. The rotating wind vane 5 is adapted to rotate relative to the vertical shaft 4. A limit ring 42 is integrally installed on the outside of the vertical shaft 4.

[0057] Both ends of the vertical support main beam 1 are provided with threaded holes 11, which are respectively threaded to the rod body 31 and the vertical shaft 4. The bottom threaded hole is not shown; refer to the top setting, as shown below. Figure 3 As shown.

[0058] At least two sets of installation interfaces 2 are provided on each side of the vertical support main beam 1;

[0059] like Figure 2As shown, each set of installation interfaces 2 includes an upper position plate 21 and a lower position plate 22, and positioning holes are provided between the upper position plate 21 and the lower position plate 22; a connecting plate 61 is provided at the end of the single bracket keel 6, and the connecting plate 61 is provided with mounting holes 62 that are adapted to the positioning holes. The connecting plate 61 is suitable for installation between the upper position plate 21 and the lower position plate 22 and is connected with a plug rod 10.

[0060] Specific implementation steps:

[0061] 1) Use a hammer to drive the drill rod 3 into the soil at the predetermined point, and connect the threaded hole at the lower end of the vertical support beam 1 to the drill rod 3.

[0062] 2) Insert the connecting plate at the end of the single bracket keel 6 between the upper and lower position plates on the vertical support main beam 1, and initially fix it with locking rods. Then connect the other single bracket keels 6 in the same way.

[0063] 3) Insert the fire-retardant fabric covering layer 9 into the keel support to seal it. In this embodiment, the four sides of the fire-retardant fabric can be fixed to the single keel support 6;

[0064] 4) Rotate the wind vane 5 on the fixed shaft via the connecting bearing, allowing it to rotate under wind force. After observing the wind direction, adjust the windproof device as a whole, ensuring the open end faces the leeward side. Personnel then enter the windproof device to perform pile welding operations. This prevents the multiple single-frame support keels from closing around the vertical support main beam.

[0065] 5) After use, pull out the plug rod 3. It can be disassembled and transferred directly. Alternatively, after removing the locking rod, rotate the single bracket keel to fold the entire device from the unfolded state, tie it with a rope, and transfer it directly.

[0066] Example 2

[0067] like Figure 7 and 8 As shown, another embodiment of the present invention is presented. Based on embodiment 1, the frame plate 63 is in the shape of a "C". A connecting plate 67 is fixedly installed at the open end of the frame plate 63, and an installation interface 2 is provided on the frame plate 63. The connecting plate 67 and the installation interface 2 are connected by a locking rod 10.

[0068] A plug 68 is mounted on the frame plate 63, and a pin 69 is detachably installed inside the plug 68. Combined with... Figure 8 As shown, the frame plate 63 is symmetrically provided with track plates 65 on one side of the prestressed pipe pile 8, and fireproof and flame-retardant cloth 7 is installed inside the track plate 65; sliding strips 66 are provided on both sides of the fireproof and flame-retardant cloth 7, the sliding strips 66 are slidably installed inside the track plate 65, and are fixed to the frame plate 63 on both sides by positioning bolts.

[0069] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
