Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to an auxiliary device for the installation and hoisting of an ultra-long steel cage inclinometer tube. Background Technology

[0002] Extra-long steel cage inclinometer tubes are specialized tubes pre-embedded inside extra-long steel cages and used in conjunction with inclinometers to monitor deep horizontal displacements in pile foundations, foundation pit retaining structures, and other similar structures. They are commonly used in large-scale projects such as super high-rise buildings, deep foundation pits, and cross-sea bridges. Currently, with the increase in building height and foundation pit depth, the application of extra-long steel cages is becoming more and more widespread, but the installation accuracy and efficiency of inclinometer tubes are becoming increasingly prominent issues.

[0003] When installing inclinometer tubes inside an extra-long steel cage, the steel cage is welded and hoisted in sections, and the inclinometer tubes can only be installed in sections as well. The inclinometer tubes in the bottom steel cage can be fixed, but the inclinometer tubes in the upper steel cage cannot be fixed and tied. During the hoisting process, the conventional S-shaped hooks cannot support the weight of the upper inclinometer tubes. In addition, the steel cage shakes during the hoisting process, which can easily cause the inclinometer tubes to fall off.

[0004] To save manpower, prevent inclinometer tubes from falling, ensure safety during hoisting, and facilitate inclinometer tube installation, this utility model proposes an auxiliary device for the installation and hoisting of ultra-long steel cage inclinometer tubes. Utility Model Content In view of the above-mentioned prior art, in order to solve the problem that conventional S-shaped hooks cannot bear the weight of the upper inclinometer tube during hoisting, and that the inclinometer tube is prone to falling due to the swaying of the steel cage during hoisting, this application provides an auxiliary device for the installation and hoisting of ultra-long steel cage inclinometer tubes.

[0005] This application provides an auxiliary device for the installation and hoisting of ultra-long steel cage inclinometer tubes, which adopts the following technical solution: An auxiliary device for installing and hoisting an ultra-long steel cage inclinometer tube includes a hook for attaching to the steel cage. A pulley block is detachably connected to the upper part of the hook. A bottom-sealed steel pipe is fixedly connected to the bottom end of the hook. An inclinometer tube body is installed on the steel pipe, with the bottom end of the inclinometer tube body located inside the steel pipe. A fixing collar is fitted and connected to the upper part of the inclinometer tube body. A rope for pulling the upper part of the inclinometer tube body is connected to the fixing collar, and the end of the rope away from the fixing collar passes through the pulley block on the hook.

[0006] By adopting the above technical solution, the integrated structure of "hook-steel pipe-fixing collar-pulley assembly" achieves stable binding between the inclinometer tube and the reinforcing cage, avoiding damage or positional displacement of the inclinometer tube due to its own weight sagging and swaying during hoisting, and adapting to the construction needs of ultra-long dimensions. At the same time, by directly attaching the hook to the reinforcing cage, the inclinometer tube and the reinforcing cage can be hoisted simultaneously, eliminating the need for separate inclinometer tube installation. This avoids the cumbersome process of installing the inclinometer tube at high altitude after hoisting the reinforcing cage, shortening the construction cycle. Furthermore, by using the pulley system to change the direction of force, the position of the inclinometer tube can be quickly adjusted by pulling the upper part of the inclinometer tube with ropes, eliminating the need for manual climbing of the reinforcing cage for binding or adjustment, reducing the risk and labor intensity of high-altitude operations, and improving construction safety and ease of operation.

[0007] Preferably, a buckle is provided at the hook above the hook to prevent the hook from falling off. One end of the buckle is connected to the hook hinge, and the other end of the buckle contacts the hook head. A torsion spring is provided on the buckle for buckle rebound and reset.

[0008] By adopting the above technical solution, the buckle provides continuous rebound tension through the torsion spring. One end is connected to the hook hinge, and the other end is in close contact with the hook head, forming a "closed locking" structure for the hook opening. When the hook is attached to the main bar of the steel cage, the torsion spring automatically drives the buckle to reset, completely sealing the opening and preventing the hook from slipping off the main bar due to the swaying of the steel cage, inertial impact, or rope traction force during hoisting.

[0009] Preferably, the pulley assembly includes a connecting plate and a plurality of pulley bodies. The side of the connecting plate closest to the hook is fixedly connected to the hook. The pulley bodies are rotatably connected to the connecting plate, and the rope is sequentially wound around the pulley bodies on the connecting plate.

[0010] By adopting the above technical solution, the multi-pulley design ensures that the tension of the rope is evenly distributed in the contact section between each pulley and the rope. This avoids excessive local wear of the rope due to excessive force on a single pulley, while also reducing the tensile deformation of the rope and improving its load-bearing safety. Furthermore, the rope is "sequentially wound" around multiple pulleys to form a fixed traction trajectory, which effectively prevents the rope from slipping out of the pulley groove, deviating, or getting knotted during traction. This ensures that the tension is always transmitted along the axis of the inclinometer tube, avoiding tilting or positioning deviation of the inclinometer tube due to tension offset, and further guaranteeing the verticality and axial consistency of the inclinometer tube.

[0011] Preferably, the fixing collar is provided with a connecting ring for connecting to the rope, and the end of the rope away from the pulley block is detachably connected to the connecting ring.

[0012] By adopting the above technical solution, one end of the rope is fixed to the connecting ring on the fixed collar. The connecting ring allows the tension of the rope to be transmitted to the fixed collar through a single point, avoiding the local pressure concentration caused by the direct winding of the rope. This not only prevents scratches and deformation on the surface of the inclinometer tube due to rope compression, but also reduces local wear on the rope, extends the service life of both, and reduces construction losses.

[0013] Preferably, the bottom of the hook is connected to a support rod for supporting the steel pipe, and the connecting rod is integrally formed with the hook.

[0014] By adopting the above technical solution, the hook and support rod form an L-shaped integral structure, which has significantly better rigidity than the split design. It can effectively resist the downward pull of the steel pipe caused by the weight of the inclinometer tube and the lateral sway during the hoisting process, avoid bending deformation of the bottom of the hook due to excessive local stress, ensure that the steel pipe always remains vertical, provide a stable limiting space for the inclinometer tube, and indirectly ensure the verticality and positioning accuracy of the inclinometer tube.

[0015] Preferably, the bottom and surface of the steel pipe are fixed to the support pipe and the hook by welding, respectively, and the steel pipe is made of stainless steel.

[0016] By adopting the above technical solution, double-point welding forms a seamless force-bearing community between the steel pipe, hook, and support rod, dispersing the longitudinal tensile force (self-weight of the inclinometer tube) and transverse shear force (hoisting sway) borne by the steel pipe. This avoids bending and torsional deformation of the steel pipe caused by single-point force, ensuring that the steel pipe always remains vertical, and indirectly guaranteeing the verticality and axial consistency of the inclinometer tube.

[0017] Preferably, the diameter of the steel pipe is larger than the diameter of the inclinometer tube, and the top of the steel pipe is given a transition treatment.

[0018] By adopting the above technical solution, the diameter of the steel pipe is larger than that of the inclinometer tube, allowing the inclinometer tube to have slight radial adjustment space within the steel pipe. When the inclinometer tube is positioned by pulling the pulley system, the operator can fine-tune the axial position of the inclinometer tube using ropes to ensure that the inclinometer tube is completely aligned with the axis of the reinforcing cage, avoiding uncorrectable positioning deviations caused by "the steel pipe and the inclinometer tube being too tightly fitted". At the same time, the steel pipe itself is fixed by welding and supported by support rods to maintain verticality, and the annular gap ensures that the inclinometer tube can be freely adjusted within the vertical steel pipe, ultimately achieving high-precision positioning of the inclinometer tube and ensuring the accuracy of subsequent inclinometer data.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model adopts an integrated structure of "hook-steel pipe-fixing collar-pulley assembly", combined with the integrated molding design of hook and support rod and the double-point welding fixing method of steel pipe, to build a high-rigidity force system, effectively resisting the self-weight tension of inclinometer tube and lateral swaying during hoisting, avoiding bending and torsional deformation of components, and ensuring that the inclinometer tube is always in a stable and limited state; 2. This utility model achieves automatic locking and closure after hooking by combining a buckle and a torsion spring at the hook, eliminating the risk of hook slippage during hoisting, further enhancing the connection stability of the overall structure, and ensuring safe and controllable construction process; 3. This utility model achieves synchronous hoisting of the inclinometer tube and the steel cage by directly attaching the hook to the steel cage, eliminating the need for separate high-altitude installation work after the steel cage is hoisted, saving cumbersome procedures, greatly shortening the construction cycle, and improving the overall construction efficiency.

[0020] 4. This utility model, through the cooperation of pulley blocks, ropes, and connecting rings, enables the adjustment of the inclinometer tube position without manual climbing of the steel cage. It can be quickly completed by pulling the rope from the ground, making the operation convenient and efficient, reducing manual input and operation time. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0024] This application discloses an auxiliary device for the installation and hoisting of an ultra-long steel cage inclinometer tube.

[0025] Reference Figure 1 and Figure 2An auxiliary device for installing and hoisting an ultra-long rebar cage inclinometer tube includes a hook 10, a pulley block 20, and a steel pipe 30. The pulley block 20 is fixed to the upper middle part of the hook 10 with bolts and nuts. The steel pipe 30 is fixed to the bottom of the hook 10, and the bottom of the steel pipe 30 is sealed, forming an integrated structure with the steel pipe 30, hook 10, and pulley block 20. By hanging the hook 10 onto the rebar cage, the entire structure consisting of the steel pipe 30, hook 10, and pulley block 20 can be hoisted together onto the rebar cage. A clinometer tube 40 is installed on the steel pipe 30, with one end of the clinometer tube 40 located inside the steel pipe 30, so that the steel pipe 30 supports the clinometer tube 40. A fixing collar 50 is fitted and connected to the surface of the clinometer tube 40. The fixing collar 50 is located in the upper middle part of the clinometer tube 40. A rope 60 is connected to the fixing collar 50. The end of the rope 60 away from the fixing collar 50 passes through the pulley block 20 to the bottom of the hook 10, so that pulling the rope 60 moves the end of the clinometer tube 40 away from the steel pipe 30 upward.

[0026] Specifically, the bottom-sealed steel pipe 30 is welded and fixed to the bottom of the hook 10, and a support rod 90 for supporting the steel pipe 30 is integrally connected to the bottom of the hook 10. The top of the support rod 90 is welded and fixed to the bottom of the steel pipe 30, so that the support rod 90 provides stable support for the steel pipe 30. Then, the fixing collar 50 is fitted onto the inclinometer tube 40, so that the fixing collar 50 is fixed to the inclinometer tube 40. One end of the rope 60 is fixed to the fixing collar 50, and the other end of the rope 60 is wrapped around the pulley block 20 and extends to the hook. At the bottom of the 10, it is easy for the operator to pull the rope 60. One end of the inclinometer tube 40 is placed inside the steel pipe 30, and the other end is moved upward by pulling the rope 60. Then, by hanging the hook 10 on the steel cage, the inclinometer tube 40 is stably hoisted. Through the integrated structure of "hook 10-steel pipe 30-fixing collar 50-pulley block 20 pieces", the inclinometer tube 40 is stably bound to the steel cage, avoiding damage or position displacement of the inclinometer tube 40 due to its own weight sagging and swaying during hoisting, and adapting to the construction needs of extra-long size.

[0027] refer to Figure 3 and Figure 4 The hook 10 is equipped with a buckle 70 at the hook above it. The buckle 70 is an arc-shaped steel plate with a thickness of 8-10mm. One end of the buckle is hinged to the side wall of the hook 10 via a stainless steel hinge, and the other end is in contact with the end face of the hook head of the hook 10. A torsion spring 80 is installed inside the hinge. One end of the torsion spring 80 is engaged in the groove of the side wall of the hook 10, and the other end abuts against the inside of the buckle 70, so that the buckle 70 is normally in contact with the hook body. When the steel cage is attached, the buckle 70 is opened by pressure and automatically springs back to lock after attachment, preventing the hook 10 from falling off during hoisting.

[0028] refer to Figure 3 and Figure 4 The pulley block 20 includes a rectangular connecting plate 21 and three pulley bodies 22 arranged side by side. The connecting plate 21 is detachably connected to the hook 10 on the side closest to the hook 10. The pulley bodies 22 are rotatably connected to the connecting plate 21 by stainless steel pins, with elastic retaining rings fitted at both ends of the pins for limiting their position. The width of the groove of the pulley body 22 is adapted to the diameter of the rope 60, and the center lines of the grooves of the two pulley bodies 22 are aligned to ensure smooth traction of the rope 60. The pulley body 22 is rotatably connected to the connecting plate 21, allowing the pulley body 22 to rotate flexibly with the traction of the rope 60. This converts the sliding friction between the rope 60 and the pulley into rolling friction, significantly reducing frictional resistance. This reduces wear on the rope 60, extends its service life, and makes the traction operation smoother, preventing traction jamming due to excessive friction.

[0029] refer to Figure 4 The fixed collar 50 is provided with a connecting ring 51 for connecting to the rope 60, and the end of the rope 60 away from the pulley block 20 is detachably connected to the connecting ring 51. By fixing one end of the rope 60 to the connecting ring 51 on the fixed collar 50, the connecting ring 51 allows the tension of the rope 60 to be transmitted to the fixed collar 50 through a single point, avoiding the local pressure concentration caused by the direct winding of the rope 60. This not only prevents scratches and deformation on the surface of the inclinometer tube due to the squeezing of the rope 60, but also reduces local wear on the rope 60, extends the service life of both, and reduces construction losses.

[0030] The diameter of the steel pipe 30 is larger than that of the inclinometer tube 40, and the top of the steel pipe 30 is made with a transition treatment to reduce wear between the steel pipe 30 and the inclinometer tube 40. When the inclinometer tube 40 is positioned by the pulley block 20, the operator can finely adjust the axial position of the inclinometer tube 40 through the rope 60 to ensure that the inclinometer tube 40 is completely aligned with the axis of the reinforcing cage, thus avoiding the inability to correct the positioning deviation caused by the "steel pipe 30 and the inclinometer tube 40 being too tightly fitted".

[0031] The implementation principle of this application embodiment is as follows: In implementation, firstly, the pulley block 20 is fixed to the hook 10 with bolts, and then the steel pipe 30 is welded and fixed to the support rod 90 and vertical section of the hook 10 to complete the main assembly of the auxiliary device; the bottom end of the inclinometer tube 40 is inserted into the steel pipe 30, and after adjusting the verticality of the inclinometer tube 40, the fixing collar 50 is placed on the upper middle part of the inclinometer tube 40 and the clamp bolts are tightened for fixation; then the hook head of the hook 10 is hooked onto the main reinforcement of the steel cage, and the buckle 70 automatically rebounds under the action of the torsion spring 80, and fits and locks with the hook head to prevent the hook 10 from falling off; one end of the rope 60 is connected to the connecting ring 51 of the fixing collar 50 through a U-shaped shackle, and the other end is wound around the pulley body 22 of the pulley block 20 in sequence, and the free end of the rope 60 is... Construction workers pull the steel cage; the hoisting equipment is started to lift the steel cage. The construction workers adjust the position of the inclinometer tube 40 by pulling the rope 60 to ensure that it remains vertical. During the hoisting process, the steel pipe 30 protects the bottom of the inclinometer tube 40. The fixing collar 50 and the rope 60 work together to prevent the inclinometer tube 40 from shifting or shaking. After the steel cage is hoisted into place, the clamp bolts of the fixing collar 50 are loosened, the fixing collar 50 is removed, the connection between the rope 60 and the connecting ring 51 is released, and finally the buckle 70 is pressed to remove the hook 10 from the steel cage, thus completing one operation. This achieves a stable binding between the inclinometer tube 40 and the steel cage, avoiding damage or positional displacement of the inclinometer tube 40 due to its own weight sagging or shaking during the hoisting process, and adapting to the construction needs of extra-long dimensions.

[0032] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
