Description

Technical Field

[0001] This utility model belongs to the field of installation tool technology, and specifically relates to a fixing device that facilitates the rapid installation of pile clamps. Background Technology

[0002] In the construction of floating docks and floating bridges, in order to prevent the floating structures from capsizing in wind and waves, the floating structures need to be connected to positioning piles through pile clamps. The floating structures restricted by the pile clamps can only float up and down along the axis of the positioning piles, thus preventing them from capsizing.

[0003] Currently, the installation method for pile grippers and floating structures is mostly on-site installation; the pile gripper includes a ring frame, rollers and positioning plates; the ring frame is a ring structure, the shape of the positioning plate matches the shape of the outer wall of the ring frame, and the center of the positioning plate is provided with positioning holes that match the cross-sectional shape of the positioning pile;

[0004] When installing the pile driver, first put the circumferential frame on the positioning pile and fix the circumferential frame to one side of the building on the water.

[0005] The positioning plate is fitted onto the positioning pile through the positioning hole. One worker on the water structure passes the connecting end of the bolt through the pre-drilled screw holes on the positioning plate and the circumferential frame to the lower end of the circumferential frame. Another worker dives underwater and connects the nut to the connecting end of the bolt. Then, a wrench or socket is used to fix the nut. At this time, the worker on the water structure can turn the bolt to cooperate with the worker underwater to tighten the bolt until the bolt and nut lock the positioning plate and the circumferential frame.

[0006] After all the bolts on the positioning plate and the circumferential frame are tightened, the workers on the surface of the structure pass the bolt ends through the pre-drilled holes in the roller support frame and the positioning plate, so that the bolt ends extend to the lower end of the positioning plate. The workers underwater complete the connection between the nut and the bolt in the same way. Two workers work together to tighten the bolt until the bolt and nut lock the support frame and the positioning plate, so as to prevent the bolts from loosening during the operation of the pile gripper and causing the components (circumferential frame, roller and positioning plate) to detach from each other.

[0007] The above-mentioned installation method for pile drivers has the following defects:

[0008] 1) Tightening the bolts and nuts requires two workers to work together, which increases labor costs, and one of the workers needs to dive underwater to fix the nuts, which poses a significant safety hazard.

[0009] 2) There are multiple bolts and nuts to be tightened on one piling holder, and multiple piling holders generally need to be installed on water-based buildings, resulting in a large workload. Moreover, the installation process is affected by hydrological conditions such as wind and waves, making the entire installation process time-consuming.

[0010] 3) The space between the side wall of the positioning pile and the side wall of the water-based building underwater is narrow, making it inconvenient for workers to enter and fix the nuts, increasing the installation difficulty. Utility Model Content

[0011] The utility model provides a fixing device for facilitating the rapid installation of a piling holder, so as to solve the technical problems in the prior art that the installation of the piling holder is difficult, inefficient, and has relatively large potential safety hazards.

[0012] The utility model is realized through the following technical solutions:

[0013] A fixing device for facilitating the rapid installation of a piling holder includes a fixed sleeve and a grip rod.

[0014] The upper end surface of the fixed sleeve is provided with a fixing hole for fixing nuts.

[0015] The grip rod is in a "U" - shaped structure. The fixed end of the grip rod is connected to the side wall of the fixed sleeve, and the gripping end of the grip rod is located above the fixed sleeve.

[0016] To better realize the utility model, further optimization is made to the above structure. The lower end surface of the fixed sleeve is provided with a through - hole for the bolt to pass through. The through - hole is communicated with the fixing hole. The diameter of the through - hole is smaller than the diameter of the fixing hole, and the axis of the through - hole coincides with the axis of the fixing hole.

[0017] To better realize the utility model, further optimization is made to the above structure. The grip rod includes a handle and a force - transmitting rod.

[0018] The force - transmitting rod includes a fixed rod and a connecting rod. The fixed end of the fixed rod is connected to the fixed end of the connecting rod, and the length direction of the fixed rod is perpendicular to the length direction of the connecting rod.

[0019] The fixed sleeve and the handle are respectively arranged at the movable ends of the fixed rod and the connecting rod.

[0020] To better realize the utility model, further optimization is made to the above structure. The fixed rod is in a cylindrical rod - like structure. A frustum - shaped connecting seat is arranged at the fixed end of the fixed rod. The diameter of the small end of the connecting seat is equal to the diameter of the fixed end of the fixed rod, and the large end of the connecting seat is connected to the fixed sleeve.

[0021] To better realize the utility model, further optimization is made to the above structure. The diameter of the large end of the connecting seat is equal to the height of the fixed sleeve.

[0022] To better realize this utility model, the above structure is further optimized, and the force transmission rod is an integrally formed component.

[0023] To better realize this utility model, the above structure is further optimized by providing an anti-slip sleeve on the grip bar, which is sleeved on the grip bar by the gripping end.

[0024] Compared with the prior art, this utility model has the following advantages:

[0025] In the fixing device provided by this utility model, the gripping rod can extend the fixing sleeve through the gap between the positioning hole on the positioning plate of the pile gripper and the positioning pile into the lower end face of the ring frame. When installing the pile gripper, the nut can be placed in the fixing hole of the fixing sleeve and pushed into the lower end face of the ring frame by the gripping rod. The worker can tighten the bolts that pass through the positioning plate and the ring frame, as well as through the support frame and the positioning plate and are connected to the nut on the water structure. The gripping rod applies a reverse load to the nut to prevent the nut from rotating. The connection between the bolt and the nut realizes the fastening of the positioning plate and the ring frame, as well as the fastening of the support frame and the positioning plate, so as to realize the quick installation of the positioning plate and the ring frame or the support frame and the positioning plate, improve the installation efficiency of the pile gripper, and the bolt tightening process can be easily completed by only one worker without entering the water to fix the nut, thereby reducing the labor cost and safety hazards in the installation process of the pile gripper.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In embodiments of this utility model, such as Figures 1 to 6 As shown, the fixing device includes a fixing sleeve 1 and a handle 2; wherein,

[0045] The upper end face of the fixed sleeve 1 is provided with a fixing hole 11 for fixing the nut;

[0046] The grip bar 2 has a "U"-shaped structure. The fixed end of the grip bar 2 is connected to the side wall of the fixed sleeve 1, and the gripping end of the grip bar 2 is located above the fixed sleeve 1. See [reference needed]. Figure 1 and Figure 2 .

[0047] When installing the pile driver, the workers can first put the ring frame 4 on the positioning pile 3 and fix the ring frame 4 to one side of the water structure 7.

[0048] Then, the positioning plate 5 is fitted onto the positioning pile 3 through the positioning hole, and the position of the positioning plate 5 is adjusted so that the screw hole reserved on the positioning plate 5 is aligned with the screw hole reserved on the circumferential frame 4.

[0049] Next, place the nut in the fixing hole 11 of the fixing sleeve 1. Using the handle 2, extend the fixing sleeve 1 through the gap between the positioning hole on the positioning plate 5 and the positioning stake 3 into the lower end face of the circumferential frame 4, aligning it with the pre-drilled screw holes on the positioning plate 5 and the circumferential frame 4. (See...) Figure 5 ;

[0050] Then, the bolts are passed through the pre-drilled screw holes on the positioning plate 5 and the pre-drilled screw holes on the ring bracket 4 from the upper end face of the positioning plate 5, and abutted against the threaded hole of the nut. The bolts are then turned by hand four to five turns to make them initially mate with the nut.

[0051] While using an electric wrench to tighten the bolt, the worker grips the handle 2 firmly and applies a reverse load to the nut through the handle 2 to prevent the nut from rotating with the bolt during the tightening process, so as to ensure that the bolt can be tightened into the nut and together with the nut, lock the positioning plate 5 and the ring bracket 4.

[0052] This fixing device can easily tighten the bolts and nuts on the pile gripper, enabling the rapid installation of the positioning plate 5 and the ring frame 4, improving the installation efficiency of the pile gripper. Moreover, the bolt tightening process can be easily completed by only one worker without having to enter the water to fix the nuts, thereby reducing the labor costs and safety hazards in the pile gripper installation process.

[0053] To ensure smoother and more stable sliding of the pile gripper along the positioning pile 3, multiple rollers 6 can be installed on the positioning plate 5. These rollers 6 are arranged circumferentially along the positioning hole, extending their rolling surfaces into the hole. This reduces friction between the positioning plate 5 and the positioning pile 3.

[0054] Roller 6 includes a wheel body and a support frame, with the wheel body rotatably mounted on the support frame; the specific installation method of roller 6 is as follows:

[0055] Place the support frame against the upper end face of the positioning plate 5 and align the screw holes on the support frame with the screw holes on the positioning plate 5. Then place the nut in the fixing hole 11 of the fixing sleeve 1 and use the gripping rod 2 to extend the fixing sleeve 1 from the gap between the positioning hole and the positioning pile 3 on the positioning plate 5 into the lower end face of the positioning plate 5 and align it with the screw holes on the positioning plate 5.

[0056] Then, pass the bolt through the pre-drilled screw holes on the support frame and the pre-drilled screw holes on the positioning plate 5 from the upper end face of the positioning plate 5, and place it against the threaded hole of the nut. Tighten the bolt by hand for four to five turns to make it initially connect with the nut.

[0057] While using an electric wrench to tighten the bolt, the worker grips the handle 2 firmly and applies a reverse load to the nut through the handle 2 to prevent the nut from rotating with the bolt during the tightening process. This ensures that the bolt can be tightened into the nut and together with the nut, lock the support frame and positioning plate 5, thus completing the installation of the roller.

[0058] The optimized version of the fixing sleeve 1 is made of high-strength alloy steel to ensure its structural strength and improve the service life of the fixing device.

[0059] In some embodiments, the lower end face of the aforementioned fixing sleeve 1 is provided with a through hole 12 for a bolt to pass through, see [reference]. Figure 2 , Figure 3 and Figure 6 ;

[0060] The through hole 12 is connected to the fixing hole 11. The diameter of the through hole 12 is smaller than the diameter of the fixing hole 11, and the axis of the through hole 12 coincides with the axis of the fixing hole 11, so that the fixing hole 11 and the through hole 12 form a stepped hole.

[0061] When the length of the bolt is much greater than the thickness of the positioning plate 5, the ring bracket 4 and the nut, during the process of tightening the bolt, when the end of the bolt passes through the bottom of the nut, the end of the bolt can pass through the through hole so that the worker can continue to tighten the bolt until the bolt and nut lock the positioning plate 5 and the ring bracket 4.

[0062] In some embodiments, the aforementioned grip bar 2 includes a handle 21 and a force transmission bar 22, see [link / reference]. Figure 3 and Figure 4 ;in,

[0063] The force transmission rod 22 includes a fixed rod 221 and a connecting rod 222. The fixed end of the fixed rod 221 is connected to the fixed end of the connecting rod 222. The length direction of the fixed rod 221 is perpendicular to the length direction of the connecting rod 222, so that the end of the force transmission rod 22 can extend to the bottom of the ring frame 4 after passing through a narrow gap, which facilitates the transmission and fixing of the nut.

[0064] The fixed sleeve 1 and the handle 21 are respectively provided with the movable end of the fixed rod 221 and the movable end of the connecting rod 222.

[0065] Preferably, the force transmission rod 22 is an L-shaped force-bearing member made of alloy round steel through a hot bending forming process. It has excellent torsional strength and rigidity, ensuring that it can stably transmit torque load and apply reverse load to the nut when fixing the nut.

[0066] In some embodiments, the fixing rod 221 described above is a cylindrical rod-shaped structure, and the fixing end of the fixing rod 221 is provided with a frustum-shaped connecting seat. See [reference needed]. Figure 2 and Figure 3 ;

[0067] The diameter of the small end of the connecting seat is equal to the diameter of the fixed end of the fixing rod 221, and the large end of the connecting seat is connected to the fixing sleeve 1, thereby increasing the connection area between the fixing rod 221 and the fixing sleeve 1 and making the connection between the fixing rod 221 and the fixing sleeve 1 more stable. Preferably, the diameter of the large end of the connecting seat is equal to the height of the fixing sleeve 1.

[0068] In some embodiments, the grip bar 2 described above is provided with an anti-slip sleeve 23, see [reference]. Figure 1 and Figure 2 ;in,

[0069] The anti-slip sleeve 23 is fitted onto the gripping end of the handle 2, increasing the roughness of the handle 2 surface to prevent the worker's hand from slipping off the handle 2 when applying a reverse load to the nut. Preferably, the anti-slip sleeve 23 is made of rubber material, which has good wear resistance, impact resistance, anti-slip properties, and sweat absorption to further improve its anti-slip effect.

[0070] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
