Description

Technical Field

[0001] This utility model relates to the field of precast column hoisting auxiliary devices, specifically a large precast column hoisting auxiliary device. Background Technology

[0002] With the rapid development of the modern construction industry, the scale of industrial buildings is constantly expanding, while the construction cycle is constantly being compressed, which puts forward higher requirements for construction safety and efficiency. In the construction of large industrial plants, the hoisting of precast columns is of paramount importance.

[0003] Currently, the hoisting of large precast columns is a key link in industrialized construction and plays an irreplaceable role in factory construction. However, the traditional dual-crane hoisting mode has significant drawbacks. For example, the current dual-crane collaborative operation requires 20 to 30 people to direct and coordinate on-site. Uneven tension on the wire rope can easily lead to the overturning of the precast column. Moreover, the hoisting process requires repeated adjustments to the actions of the two machines and the posture of the column. At the same time, the column base lacks effective support during the dragging process on the ground, which greatly increases the cost of later repairs. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an auxiliary device for hoisting large precast columns, so as to solve the technical problems of large workload of manual coordination, high risk of overturning due to force imbalance, low hoisting efficiency and severe wear and tear of column base in the traditional double-crane hoisting mode.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large precast column hoisting auxiliary device, comprising a moving mechanism and an adjusting mechanism, wherein the moving mechanism includes a flat plate support, a drag seat and moving wheels, and the adjusting mechanism is arranged side by side with the moving mechanism on the ground;

[0006] The support bracket is hinged to the top of the flat plate support. The support bracket is used to support the column foot end of the precast column. The movable wheel is fixed to the four corners of the bottom surface of the flat plate support. The movable wheel includes a universal wheel seat, a rotating wheel and a tire lock.

[0007] The support is provided with elastic straps, the two ends of which are detachably connected to the edge of the support. The adjustment mechanism includes an adjustment support for supporting the other end of the precast column. An electric push rod is vertically installed at the bottom of the adjustment support.

[0008] By adopting the above technical solution, the device fixes the column foot end by the drag seat of the moving mechanism and independently supports the other end by the adjusting mechanism, eliminating the risk of coordination when lifting by two cranes; the elastic straps prevent the column foot from being dragged and worn; and the moving wheels of the flat plate support enable the column foot to move with the movement.

[0009] Furthermore, the support includes a support frame and a mounting groove, the mounting groove being located on one side of the support frame, the hinge being embedded in the mounting groove, and the rotation axis of the hinge being parallel to the length direction of the support.

[0010] By adopting the above technical solutions, the mounting groove of the bracket precisely positions the hinge, ensuring that its rotation axis is parallel to the length direction of the bracket, so that the column foot end rotates axially without deviation when the precast column is flipped; the bracket frame enhances the bending strength of the bracket and avoids overload deformation.

[0011] Furthermore, the universal wheel seat is bolted to the bottom surface of the flat plate support, the rotating wheel is connected to the bottom of the universal wheel seat through a bearing, and the tire lock is a ratchet structure located at the outer end of the rotating wheel axle.

[0012] By adopting the above technical solutions, the universal wheel seat bolt fixation improves the connection rigidity between the flat plate support and the moving wheel; the ratchet tire lock achieves millisecond-level braking of displacement overspeed by locking the outer end of the wheel axle; and the bearing reduces the frictional resistance of the rotating wheel.

[0013] Furthermore, a level observation instrument is embedded in the side wall of the adjusting support. The level observation instrument is a bubble level. A rubber block is bonded to the bottom of the electric push rod. The contact surface of the rubber block with the ground is provided with anti-slip texture.

[0014] By adopting the above technical solution, the level observation instrument is embedded in the side wall of the adjusting support to facilitate real-time observation of the horizontal deviation; the anti-slip texture of the rubber block at the bottom of the electric actuator enhances the ground friction and prevents the adjusting support from sliding during the leveling operation.

[0015] Furthermore, the adjustment mechanism also includes an electric regulator, which is electrically connected to the electric push rod via a circuit line.

[0016] By adopting the above technical solution, the electric regulator controls the extension and retraction of the electric push rod through the circuit, replacing the manual leveling operation; the circuit simplifies the complexity of electrical connections.

[0017] Furthermore, the circuit line is a shielded cable, which is routed along the side wall of the adjusting support.

[0018] By adopting the above technical solution, the shielded cable circuit is routed along the side wall of the adjusting support to avoid cable breakage caused by mechanical wear; the side wall routing isolates the electrical control system from interference with the lifting mechanism.

[0019] Furthermore, the horizontal observation instrument is equipped with a transparent protective cover, which is bolted to the side wall of the adjusting support, and the area of ​​the rubber block is larger than the bottom cross-section of the electric actuator.

[0020] By adopting the above technical solutions, the transparent protective cover of the horizontal observation instrument is fixed with bolts for dust and water resistance; the area of ​​the rubber block is increased to improve the stability of the support.

[0021] Furthermore, the electric regulator is equipped with a lifting control button and a power indicator light on its surface, and the connection between the circuit wire and the electric push rod is covered with a waterproof sleeve.

[0022] By adopting the above technical solutions, the buttons and indicator lights of the electric regulator can intuitively display the operating status; the waterproof sleeves of the circuit wires seal the cable interfaces to prevent leakage and short circuits.

[0023] In summary, the present invention has the following main advantages:

[0024] This utility model incorporates components such as a support base, hinges, casters, and elastic straps. The support base is constructed from high-strength steel plate welded together with a non-slip rubber layer, providing excellent pressure resistance and wear resistance. The casters integrate universal wheel seats and ratchet-type tire locks, achieving low-friction displacement through bearing-connected rotating wheels. During operation, the precast column's base is placed on the support base, and the edges of the support base are locked in place using hooks on both ends of the elastic straps, rigidly fixing the column base to the support base. The other end of the precast column is mounted on an adjusting support. An electric actuator levels the column based on data from a leveling instrument. When the truck crane lifts... During the prefabrication of the column, the column base is driven by traction force to move the trailer synchronously. The hinge adapts to the changes in the column's tilt angle in real time, and the moving wheels autonomously turn along the crane's direction of travel. Once the column's posture becomes unbalanced or the displacement speed exceeds the limit, the ratchet structure of the tire lock instantly locks the rotating wheel to prevent the column base from sliding and colliding. In addition, the anti-slip surface of the trailer and the elastic strap form a double fixing barrier, completely isolating the column base from friction and wear. The rigid-flexible coupling structure of the hinge and the universal wheel seat ensures that the column is always controlled during 0-90° rotation. The millisecond-level mechanical locking response of the tire lock provides active safety protection for operations in narrow spaces. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] A large precast column hoisting auxiliary device, such as Figure 1-4 As shown, it includes a moving mechanism 1 and an adjusting mechanism 2. The moving mechanism 1 includes a flat plate support 101, a drag seat 102 and a moving wheel 103. The adjusting mechanism 2 is arranged on the ground in parallel with the moving mechanism 1.

[0032] The support 102 is mounted on the top of the flat support 101 via a hinge 1023. The support 102 is used to support the column foot end of the precast column. The movable wheel 103 is fixed to the four corners of the bottom surface of the flat support 101. The movable wheel 103 includes a universal wheel seat 1031, a rotating wheel 1032 and a tire lock 1033.

[0033] The support 102 is equipped with an elastic strap 104, the two ends of which are detachably connected to the edge of the support 102. The adjustment mechanism 2 includes an adjustment support 201, which is used to support the other end of the precast column. An electric actuator 202 is vertically installed at the bottom of the adjustment support 201. The support 102 of the moving mechanism 1 supports and fixes the column foot of the precast column. The adjustment support 201 of the adjustment mechanism 2 independently supports the other end of the column, forming a double-point separation support structure, which completely eliminates the need for the coordination of two cranes. The universal wheel seat 1031 and the rotating wheel 1032 of the moving wheel 103 realize the follow-up displacement of the flat support 101, avoiding the column foot from dragging on the ground. The elastic strap 104 is rigidly connected to the edge of the support 102 through buckles at both ends, which isolates the column foot from friction damage. The electric actuator 202 vertically supports the adjustment support 201, providing a basis for dynamic leveling.

[0034] See Figure 3 , Figure 4 The support 102 includes a support frame 1021 and a mounting groove 1022. The mounting groove 1022 is located on one side of the support frame 1021. A hinge 1023 is embedded in the mounting groove 1022. The rotation axis of the hinge 1023 is parallel to the length direction of the support 102. The rectangular frame structure of the support frame 1021 improves the overall bending strength of the support 102 and prevents plastic deformation caused by the pressure of the precast column. The U-shaped positioning design of the mounting groove 1022 at the four corners of the support frame 1021 ensures that the base hinge of the hinge 1023 is accurately embedded. The parallel layout of the rotation axis of the hinge 1023 with the length direction of the support 102 ensures that the column foot rotates only along a single axis during the 0-90° rotation of the precast column, eliminating the risk of displacement of the support 102 caused by torsional stress.

[0035] See Figure 1 , Figure 4 The universal wheel seat 1031 is bolted to the bottom surface of the flat plate support 101. The rotating wheel 1032 is connected to the bottom of the universal wheel seat 1031 through a bearing. The tire lock 1033 is a ratchet structure and is located at the outer end of the wheel axle of the rotating wheel 1032. The universal wheel seat 1031 is fastened to the bottom surface of the flat plate support 101 with bolts, which improves the overall shear strength of the moving wheel 103. The rotating wheel 1032 is connected to the bottom of the universal wheel seat 1031 through a ball bearing, which converts sliding friction into rolling friction and reduces displacement energy consumption. The ratchet tire lock 1033 is located at the outer end of the wheel axle of the rotating wheel 1032. It uses the ratchet one-way locking principle to lock the wheel axle instantly when the displacement of the tow seat 102 exceeds the speed, forming a mechanical active protection.

[0036] See Figure 3 , Figure 4 The adjustable support 201 has a level observation instrument 204 embedded in its side wall. The level observation instrument 204 is a bubble level. A rubber block 203 is bonded to the bottom of the electric actuator 202. The contact surface of the rubber block 203 with the ground has anti-slip texture. The bubble level observation instrument 204 is embedded in the observation port of the side wall of the adjustable support 201, allowing the operator to directly read the column inclination angle data. The rubber block 203 is bonded to the bottom of the electric actuator 202 through a high-viscosity adhesive layer. The anti-slip texture on its bottom adopts an interlaced groove design to increase the static friction coefficient between the rubber block 203 and the ground. During the raising and lowering of the adjustable support 201, the deformation of the rubber block 203 buffers the shock and vibration, and works with the anti-slip texture to prevent displacement.

[0037] See Figure 1 , Figure 2 The adjustment mechanism 2 also includes an electric regulator 206, which is electrically connected to the electric push rod 202 via a circuit line 205. The output port of the electric regulator 206 is connected to the motor interface of the electric push rod 202 via the circuit line 205, converting the lifting command into an electrical signal for transmission. The operator controls the extension and retraction of the electric push rod 202 via the button on the electric regulator 206, precisely replacing manual adjustment. The direct connection architecture of the circuit line 205 eliminates the need for intermediate relays, reducing the system failure rate.

[0038] See Figure 3 , Figure 4 The circuit line 205 is a shielded cable, which is routed along the side wall of the adjusting support 201. The circuit line 205 uses a copper mesh shielded cable to isolate the influence of external electromagnetic interference on the electrical signal. The circuit line 205 is routed along the wire groove on the side wall of the adjusting support 201 to keep the circuit line 205 away from the telescopic movement area of ​​the electric push rod 202. The wire groove is fixed to prevent the circuit line 205 from rubbing and cutting against the metal edge of the adjusting support 201, thus ensuring electrical safety.

[0039] See Figure 1 , Figure 2The horizontal observation instrument 204 is equipped with a transparent protective cover, which is bolted to the side wall of the adjusting support 201. The area of ​​the rubber block 203 is larger than the bottom cross-section of the electric actuator 202. The transparent protective cover of the horizontal observation instrument 204 is fastened to the side wall of the adjusting support 201 by bolts to prevent rainwater and dust from entering the bubble cavity and interfering with the observation accuracy. The design of the rubber block 203 covering an area larger than the bottom cross-section of the electric actuator 202 allows the edge of the rubber block 203 to extend beyond the outer diameter of the electric actuator 202. The increased grounding area disperses the pressure of the adjusting support 201 and suppresses the settlement of the soft soil foundation.

[0040] See Figure 1 , Figure 4 The electric regulator 206 has a lifting control button and a power indicator light on its surface. The connection between the circuit wire 205 and the electric push rod 202 is covered with a waterproof sleeve. The lifting control button on the surface of the electric regulator 206 triggers the action signal of the electric push rod 202, and the power indicator light displays the power status in real time. The waterproof sleeve at the connection between the circuit wire 205 and the electric push rod 202 adopts a silicone sealing ring compression structure to prevent rainwater from seeping in along the interface. The internal thread tightening design of the waterproof sleeve strengthens the cable's tensile strength.

[0041] The implementation principle of this embodiment is as follows: First, the flat plate support 101 of the moving mechanism 1 and the adjusting support 201 of the adjusting mechanism 2 are placed side by side at the designated position for the hoisting of the precast column, and the rotating wheel 1032 is locked by the tire lock 1033 of the moving wheel 103.

[0042] Next, place the base of the precast column on the support 102 of the flat plate support 101 and fix it to the edge of the support 102 by the elastic straps 104 at both ends; the other end of the precast column is mounted on the adjusting support 201, and the electric adjuster 206 is operated to control the electric push rod 202 to rise and fall, and the precast column is leveled by combining the data of the level observation instrument 204.

[0043] Subsequently, the tire lock 1033 is released, and the crane lifts the top of the precast column; the column foot end pulls the drag seat 102 to move, the hinge 1023 rotates along the axis to adapt to the change of column inclination angle, and the moving wheel 103 autonomously turns and moves with the crane through the universal wheel seat 1031; if the displacement speed exceeds the limit, the ratchet structure of the tire lock 1033 instantly locks the rotating wheel 1032.

[0044] Finally, when the precast column is erected to 90°, the elastic strap 104 is released, and the crane lifts the precast column to the installation position to complete the hoisting.
