Technical Field

[0001] This invention belongs to the field of infrastructure construction such as high-speed rail and buildings, and specifically relates to a complete set of devices for vertically lowering auxiliary steel cages. Background Technology

[0002] Traditional methods of lowering rebar cages require a crane to suspend and lift the cage before slowly lowering it into the wellhead. This process presents numerous problems: the cage sways significantly at the bottom, making precise and rapid lowering difficult, especially in muddy formations where the cage may tilt after being placed in the well, leading to lowering failure and severely impacting construction progress; furthermore, multiple workers are needed to manually align the cage with the wellhead, resulting in poor alignment, wasting time and effort, and posing serious safety hazards to the workers.

[0003] Therefore, how to achieve rapid and accurate vertical lowering of steel cages during construction, saving manpower, material resources, and financial resources, and ensuring worker safety, is a technical problem that this field is eager to solve. Summary of the Invention

[0004] The purpose of this invention is to provide a complete set of auxiliary steel cage vertical lowering devices that are simple to operate, safe and efficient, especially for formations with large wellheads where steel cages need to be lowered and siltation conditions, enabling rapid and accurate vertical lowering of steel cages.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a complete set of auxiliary steel cage vertical lowering devices, characterized in that: it includes a moving mechanism, an output mechanism, and a straightening buckle; the moving mechanism includes a vehicle body and tracks; the output mechanism includes hydraulic plates a, b, c, and d, rollers, a transmission belt, and a motor; the hydraulic plates a, b, c, and d are sequentially connected by sliding grooves and can move along the sliding grooves themselves; the hydraulic plates a, b, c, and d are connected by sliding grooves and can move along the sliding grooves themselves; the hydraulic plates a, b, c, and d are connected by sliding grooves and tracks, rollers, a transmission belt, and a motor. The plate d is equipped with hydraulic rods and hydraulic cylinders to connect the upper and lower components and achieve hydraulic drive; the straightening buckle includes a straightening ring, a straightening belt, double concave rings, a single convex ring, a locking screw, and a locking nut; the straightening buckle is semi-circular in shape, and a single straightening buckle contains two straightening rings and three straightening belts, with two double concave rings on one side and two single convex rings on the other side. When working, the two straightening buckles are installed as a whole, with the double concave ring of one straightening buckle engaging with the single convex ring of the other straightening buckle, and locked by the locking screw and locking nut.

[0006] Preferably, the hydraulic plate b includes a hydraulic cylinder b, a dovetail groove, an observation groove, a sliding groove b, and a hydraulic rod b. It is connected to the hydraulic plate a through the dovetail groove, and the hydraulic rod b is connected to the hydraulic cylinder of the hydraulic plate a to achieve vertical movement. It is connected to the hydraulic rod of the hydraulic plate c through the hydraulic cylinder b, and the sliding groove b is connected to the hydraulic plate c to achieve horizontal movement of the hydraulic plate c.

[0007] Preferably, the single hydraulic plate d cooperates with two rollers, the two rollers are covered with a transmission belt, and each roller is engaged with a motor via a shaft, so that the motor can drive the rollers to rotate, and ultimately drive the transmission belt to move.

[0008] Preferably, the straightening band on the straightening buckle is in the shape of an outwardly convex arc, and the straightening band is connected to the straightening ring by welding or other means.

[0009] Preferably, the observation groove on the hydraulic plate b is U-shaped, which makes it easy for the operator to observe the clamping condition of the transmission belt and the steel cage inside the vehicle.

[0010] Preferably, the vehicle body contains a cab and the power components of the entire device. The operator in the cab can operate the hydraulic system and control the rotation of the motor. The power components are connected to the tracks, which replace conventional tires, so that the vehicle body can move under various harsh working conditions on site.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) The hydraulic plates a, b, c, and d are connected by a sliding groove and hydraulic rods and hydraulic cylinders are respectively set, which can realize the movement adjustment in six degrees of freedom, ensure that the transmission belt can stably fit the steel cage, and realize the centering of the lower end of the steel cage.

Detailed Implementation

[0015] The invention will now be further described with reference to the accompanying drawings.

[0016] like Figure 1-5 As shown, the auxiliary steel cage vertical lowering assembly is characterized in that: the auxiliary steel cage vertical lowering assembly includes: a moving mechanism, an output mechanism, and a straightening buckle 2; the moving mechanism includes a vehicle body 6 and a track 16; the output mechanism includes a hydraulic plate a13, a hydraulic plate b15, a hydraulic plate c9, a hydraulic plate d10, a roller 11, a transmission belt 12, and a motor 14; the straightening buckle 2 includes a straightening ring 201, a straightening belt 202, a double concave ring 203, a single convex ring 204, a locking screw 8, and a locking nut 7.

[0017] like Figure 2 , Figure 3 As shown, in one embodiment, the hydraulic plates a13, b15, c9, and d10 are connected sequentially by a sliding groove and can move along the sliding groove. Hydraulic rods and hydraulic cylinders are respectively provided on the hydraulic plates a13, b15, c9, and d10 for connecting the upper and lower components and realizing hydraulic drive.

[0018] like Figure 2 , Figure 3As shown, in one embodiment, the single hydraulic plate d10 cooperates with two rollers 11, the two rollers 11 are covered with a transmission belt 12, and each roller 11 is engaged with a motor 14 via a shaft, so that the motor 14 can drive the roller 11 to rotate, and ultimately drive the transmission belt 12 to move.

[0019] like Figure 2 , Figure 4 As shown, in one embodiment, the hydraulic plate b15 includes a hydraulic cylinder b151, a dovetail groove 152, an observation groove 153, a sliding groove b154, and a hydraulic rod b155. It is connected to the hydraulic plate a13 via the dovetail groove 152, and the hydraulic rod b155 is connected to the hydraulic cylinder of the hydraulic plate a13, enabling vertical movement. It is also connected to the hydraulic rod of the hydraulic plate c9 via the hydraulic cylinder b151, and the sliding groove b154 is connected to the hydraulic plate c9, enabling horizontal movement of the hydraulic plate c9. The observation groove 153 on the hydraulic plate b15 is U-shaped, facilitating the operator's observation of the clamping condition of the transmission belt 12 and the reinforcing cage 5 within the vehicle body 6.

[0020] like Figure 5 As shown, in one embodiment, the straightening buckle 2 is semi-circular in shape. Each straightening buckle 2 contains two straightening rings 201 and three straightening straps 202. One side has two double concave rings 203, and the other side has two single convex rings 204. During operation, the two straightening buckles 2 are assembled as a whole. The double concave rings 203 of one straightening buckle 2 cooperate with the single convex rings 204 of the other straightening buckle 2, and are locked by locking screws 8 and locking nuts 7. The straightening straps 202 on the straightening buckle 2 are convex arc-shaped, and the straightening straps 202 are connected to the straightening rings 201 by welding or other methods.

[0021] like Figure 1As shown, in one embodiment, the construction process of the auxiliary rebar cage vertical lowering device of the present invention is as follows: When the rebar cage 5 needs to be lowered at the construction site, the vibrator 3 is first connected to the vibrator rod 4, and the rebar cage 5 is connected to the upper end of the vibrator rod 4. At this time, a worker operates the crane 1 to use the hook to lift the vibrator 3, the vibrator rod 4 and the rebar cage 5 together to the vicinity of the well opening, and then another worker drives the vehicle body 6 to the rebar cage 5. By controlling the movement of hydraulic plates a12, b15, c9 and d10, the transmission belt 12 clamps the lifted rebar cage 5. This not only stabilizes the lower end of the rebar cage 5, but also adjusts the position of the rebar cage 5 by controlling the movement of hydraulic plates a12, b15, c9 and d10 to ensure that the rebar cage 5 is completely aligned with the well opening. Further, a worker installs two straightening buckles 2 at the lower end of the rebar cage 5, and installs locking screws 8 and locking nuts 7 in conjunction. Then, one worker starts the crane 1, controlling the hoisting rope to slowly lower it, while another worker starts the motor 14. The rotation of the roller 11 drives the transmission belt 12, ultimately causing the reinforcing cage 5 to move down. The centering buckle 2 also descends into the well along with the reinforcing cage 5. If the reinforcing cage 5 is slightly tilted relative to the well wall, the centering buckle 2 will generate a rebound force through its external convex arc-shaped centering belt 202 to assist in centering and correct the tilt. After the reinforcing cage 5 is lowered, the connection between the reinforcing cage 5 and the vibrator 4 is disconnected. The crane 1 is then started to lift the vibrator 3 and the vibrator 4, and a new reinforcing cage 5 is connected. The vehicle 6 is then driven to another wellhead location to lower a new reinforcing cage 5.

[0022] The auxiliary steel cage vertical lowering device provided by this invention replaces the traditional method of several workers manually controlling the lowering and centering of the steel cage. The entire process is mechanized, using hydraulic and motor control systems. The entire process achieves efficient, accurate, and safe vertical lowering of the steel cage, greatly reducing the input of manpower, material resources, and financial resources, and ensuring the safety of workers. It has significant advantages, especially in situations where steel cages need to be lowered into large wellheads and in silt formations.
