DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] When hoisting the steel cage, the hoisting equipment in the prior art usually first uses ropes to tie the steel cage, and then fixes the ropes for tying the steel cage to the hooks. This is not only inefficient, but also the steel cage is prone to swaying greatly due to inertia during the hoisting process, making it difficult to quickly and accurately place the steel cage inside the casting mold. In order to solve this technical defect in the prior art, Figure 1 as well as Figure 4-Figure 8As shown, this embodiment proposes a lifting device for processing crack-resistant reinforced concrete culverts, which can effectively limit the steel wire sling 305 during the lifting process, and can effectively prevent the culvert steel cage 2 from swinging greatly due to inertia. The culvert steel cage 2 is placed on the lifting platform 1 of the equipment, and the lifting platform 1 is provided with a cage lifting mechanism 3 for quickly transferring the culvert steel cage 2. The cage lifting mechanism 3 is provided with an anti-swaying and correcting mechanism 4 for maintaining the stability of the steel cage. The lifting platform 1 is provided with a steel cage soaking mechanism to improve the corrosion resistance. The anti-corrosion immersion mechanism 5 and the side of the lifting platform 1 are provided with a cage conveying mechanism 6. When the reinforced concrete culvert is processed, first, the cage conveying mechanism 6 will convey the rolled culvert steel cage 2 to one side of the lifting platform 1. Next, the cage lifting mechanism 3 will lift the culvert steel cage 2 into the anti-corrosion immersion mechanism 5 for immersion, thereby improving the firmness of the connection between the culvert steel cage 2 and the concrete. During the lifting process, the anti-sway and deviation correction mechanism 4 will limit the position of the culvert steel cage 2 to avoid large shaking of the culvert steel cage 2.

[0039] In order to prevent the steel wire sling 305 from shaking greatly during movement and improve stability, the present embodiment is provided with an anti-sway and deviation-correcting mechanism 4. Specifically, the anti-sway and deviation-correcting mechanism 4 includes a fixed protrusion 401 fixedly installed at the end of the steel wire sling 305. The fixed protrusion 401 is provided with a plurality of branch steel cables 402 in an array along the circumferential direction. A lifting circular plate 403 is provided below the fixed protrusion 401. The branch steel cables 402 are fixedly connected to the lifting circular plate 403. A mounting cylinder 404 is fixedly installed on the lifting circular plate 403. A fixed disc 405 is fixedly installed at the lower end of the mounting cylinder 404. A movable support foot 40 is provided on the fixed disc 405. 6. Several movable legs 406 are arranged along the circumferential direction of the fixed disc 405. The movable legs 406 are slidably connected with the fixed disc 405. A sealing rubber ring is arranged on the fixed disc 405. When the inflation component 407 is powered on, multiple movable legs 406 are extended outward at the same time. The interior of the mounting cylinder 404 is provided with an inflation component 407. The inflation component 407 includes a small air pump fixedly installed inside the mounting cylinder 404. The exhaust end of the small air pump is connected with an exhaust vertical pipe. The exhaust vertical pipe extends to the interior of the fixed disc 405. When the small air pump is running, air is input into the interior of the fixed disc 405 through the exhaust vertical pipe. A return spring 408 is fixedly connected between the inflatable component 407 and the movable support foot 406, a mounting cross bar 409 is movably installed on the movable boom 303, a micro motor for driving the mounting cross bar 409 to rotate is arranged inside the movable boom 303, a horizontal sensor is arranged on the mounting cross bar 409, when the inclination angle of the movable boom 303 changes, the mounting cross bar 409 will rotate under the drive of the micro motor, so as to ensure that the mounting cross bar 409 is always parallel to the lifting platform 1, a limit block 410 is arranged on the mounting cross bar 409, the length of the mounting cross bar 409 is adjustable, a vertical circular hole is penetrated on the limit block 410, and the telescopic circle The tube 411 is coaxially arranged with the vertical circular hole, and a horizontal sensor is arranged on the mounting cross bar 409. When the inclination angle of the movable boom 303 changes, the angle between the wire sling 305 and the movable boom 303 will also change. At this time, the mounting cross bar 409 will automatically extend horizontally, thereby ensuring that the wire sling 305 can be in a vertical state. A telescopic circular tube 411 is fixedly installed at the lower end of the limiting protrusion 410, and a position sensor 412 is coaxially arranged at the lower end of the fixed disc 405. The wire sling 305 passes through the inside of the limiting protrusion 410 and the telescopic circular tube 411, and the lower end of the telescopic circular tube 411 is fixedly connected to the fixed protrusion 401.

[0040] According to the above content, when the steel cage is hoisted, first, the installation cylinder 404 and the fixed disc 405 will enter the interior of the culvert steel cage 2 under the action of the cage hoisting mechanism 3. After reaching the specified height, the small air pump will automatically inflate the interior of the fixed disc 405 through the exhaust riser, so that the multiple movable legs 406 are extended outward at the same time. Figure 3As shown, the movable legs 406 are extended and inserted into the inner part of the side wall of the steel cage.

[0041] Next, the installation cylinder 404 will move upwards under the action of the steel wire sling 305, thereby lifting the culvert reinforcement cage 2. At the same time, the rotating bracket 302 will slowly rotate under the action of the driving motor, thereby rotating and transporting the culvert reinforcement cage 2.

[0042] Moreover, if Figure 4 As shown, during the rotational transportation process, the wire sling 305 passes through the inside of the limiting protrusion 410 and the telescopic circular tube 411 in turn, and at this time, the length of the installation cross bar 409 is fixed, so the limiting protrusion 410 and the telescopic circular tube 411 can continuously limit the wire sling 305, which can effectively prevent the culvert steel cage 2 from shaking at a large angle during the rotational transportation process.

[0043] When the position sensor 412 moves to the top of the immersion pool 507, the rotating bracket 302 stops rotating. Next, the mounting cylinder 404 moves vertically downward under the action of the wire sling 305, thereby placing the culvert steel cage 2 into the immersion pool 507. After the immersion is completed, the steel cage is transferred to the casting pool (the casting pool and the immersion pool 507 are symmetrically arranged on both sides of the fixed base 301) in the same way.

[0044] In this embodiment, by setting up the anti-sway and deviation-correcting mechanism 4 and utilizing the mutual cooperation between the limiting protrusion 410 and the telescopic round tube 411, the steel wire sling 305 can be continuously and effectively limited during the lifting process, which can effectively prevent the culvert steel cage 2 from swinging greatly due to inertia, and there is no need for the staff to perform auxiliary limiting on the culvert steel cage 2 below; moreover, in this embodiment, by setting up the anti-sway and deviation-correcting mechanism 4 and utilizing the mutual cooperation between the inflatable component 407 and the movable support leg 406, the lifting and unloading of the steel cage can be completed quickly, without using ropes to fix the culvert The culvert reinforcement cage 2 is tied up, which can effectively improve the lifting efficiency and ensure the safety during the lifting process; in addition, the present embodiment sets an anti-sway and deviation correction mechanism 4, and utilizes the mutual cooperation between the telescopic circular tube 411 and the branch steel cable 402. When the culvert reinforcement cage 2 is vertically transported, the telescopic circular tube 411 will synchronously extend or contract with the movement of the lifting circular plate 403. At the same time, multiple branch steel cables 402 will work together to maintain the stability of the installation cylinder 404, thereby ensuring that the culvert reinforcement cage 2 can accurately enter the interior of the immersion circular pool 507 or the casting pool.

[0045] Embodiment 2

[0046] In order to improve the hoisting efficiency of the culvert reinforcement cage 2 as much as possible and reduce the labor intensity of the staff, on the basis of the first embodiment, as shown in FIG. Figure 1-Figure 4As shown, the present embodiment is provided with a cage hoisting mechanism 3. Specifically, the cage hoisting mechanism 3 comprises a fixed base 301 fixedly mounted on the hoisting platform 1, a rotating bracket 302 is movably mounted on the fixed base 301, a movable boom 303 is rotatably connected to the rotating bracket 302, a driving motor 304 for driving the movable boom 303 to rotate up and down is fixedly mounted on the side of the rotating bracket 302, a steel wire sling 305 is arranged on the movable boom 303, a driving motor for driving the rotating bracket 302 to rotate is arranged inside the hoisting platform 1, a winding assembly 306 for winding or releasing the steel wire sling 305 is arranged on the movable boom 303, and the winding assembly 306 includes The utility model comprises an installation box fixedly installed on the movable boom 303, a winding drum is movably installed inside the installation box, a winding motor driving the winding drum is fixedly installed outside the installation box, one end of the wire rope 305 is fixedly connected to the winding drum, the other end of the wire rope 305 passes around the top pulley 307 and is fixedly connected to the fixed protrusion 401, when the winding drum rotates, the wire rope 305 is wound or released, a top pulley 307 is movably installed on the top of the movable boom 303, a lubricating square cover 308 is arranged outside the movable boom 303, a viscous lubricating oil is arranged inside the lubricating square cover 308, and the wire rope 305 passes through the inside of the lubricating square cover 308.

[0047] According to the above content, when the driving motor is powered on, the rotating bracket 302 will rotate at a constant rate. During the lifting process, the mounting cylinder 404 is initially located above the cage conveying mechanism 6. Next, the mounting cylinder 404 will be moved to the top of the immersion pool 507 and the casting pool in turn under the action of the rotating bracket 302.

[0048] When the installation cylinder 404 is located directly above the immersion pool 507 or the casting pool, the winding drum will release the steel wire sling 305 under the action of the winding motor, so that the culvert reinforcement cage 2 enters the immersion pool 507 or the casting pool.

[0049] Moreover, if Figure 4 As shown, during the movement of the steel wire sling 305 , it will always pass through the inside of the lubricating cover 308 . At this time, the lubricating oil inside the lubricating cover 308 will adhere to the surface of the steel wire sling 305 , thereby lubricating and cooling the steel wire sling 305 .

[0050] The present embodiment provides a cage hoisting mechanism 3, and utilizes the cooperation between the winding assembly 306 and the rotating bracket 302, so that the culvert steel cage 2 can be automatically and accurately transported to the inside of the immersion pool 507 and the casting pool without manual operation by the staff, which can effectively improve the processing efficiency of the reinforced concrete culvert and is easy to use; moreover, the present embodiment provides a cage hoisting mechanism 3, and utilizes the cooperation between the lubrication assembly 308 and the winding assembly 306, so that the steel wire sling 305 can be automatically cooled and lubricated during the hoisting process, which can effectively reduce the wear of the steel wire sling 305.

[0051] Embodiment 3

[0052] In order to improve the bonding strength between the culvert steel cage 2 and the concrete and improve the crack resistance of the reinforced concrete culvert, Figure 1 , Figure 2 , Figure 8 as well as Fig. 9 As shown, on the basis of the above embodiment, the present embodiment is provided with an anti-corrosion immersion mechanism 5. Specifically, the anti-corrosion immersion mechanism 5 includes a fixed collar 501 coaxially arranged on the outside of the mounting cylinder 404, a driving gear shaft 502 is arranged inside the fixed collar 501, a movable ring 503 is movably installed on the fixed collar 501, a plurality of rectangular square tubes 504 are equidistantly arranged outside the movable ring 503, a limiting assembly 505 is movably installed on the rectangular square tube 504, the limiting assembly 505 includes an electric push rod fixedly installed inside the rectangular square tube 504, a limiting rubber block is slidably connected to the rectangular square tube 504, and the limiting rubber block is connected to the electric push rod The push rod is fixedly connected. When the electric push rod is extended, the limiting rubber block will contact the inner wall of the culvert steel cage 2, thereby preventing relative sliding between the culvert steel cage 2 and the movable support leg 406 during the lifting process. A fixed gear ring 506 is inlaid on the inner wall of the movable ring 503, and the fixed gear ring 506 is meshed with the driving gear shaft 502. The lifting platform 1 is symmetrically provided with an immersion pool 507 and a casting pool. A rotating bottom plate 508 is movably installed inside the immersion pool 507. A material receiving disc 509 is provided on the side of the lifting platform 1. When the driving gear shaft 502 rotates, the movable ring 503 will rotate through cooperation with the fixed gear ring 506.

[0053] According to the above content, during the lifting process, multiple limiting rubber blocks will contact the inner wall of the culvert steel cage 2 at the same time under the action of the electric push rod, thereby preventing relative sliding between the culvert steel cage 2 and the movable support legs 406 during the lifting process, and effectively preventing the culvert steel cage 2 from falling.

[0054] Moreover, when the installation cylinder 404 moves to the top of the immersion pool 507, the culvert steel cage 2 will move downward synchronously with the installation cylinder 404 until the lower end of the culvert steel cage 2 contacts the rotating bottom plate 508. At this time, the movable support leg 406 will shrink to the inside of the fixed disc 405 under the action of the reset spring 408. Next, the culvert steel cage 2 will contact the surfactant in the immersion pool 507, thereby improving the bonding force between the culvert steel cage 2 and the concrete, which can prevent the reinforced concrete culvert from cracking during use to a certain extent.

[0055] Subsequently, the movable ring 503 will rotate at a constant rate under the action of the driving gear shaft 502. When the movable ring 503 rotates, the limiting rubber block will rotate synchronously, so that the culvert steel cage 2 can rotate at a constant rate, which can effectively improve the uniformity of contact between the culvert steel cage 2 and the mixed coating, so that the coating can be evenly adhered to the surface of the culvert steel cage 2.

[0056] After the soaking is completed, the installation cylinder 404 will lift the culvert reinforcement cage 2 upwards and transport it from above the receiving disc 509 to above the casting pool. During the transportation process, the excess surfactant on the culvert reinforcement cage 2 will fall into the inside of the receiving disc 509.

[0057] In this embodiment, by providing an anti-corrosion immersion mechanism 5 and utilizing the mutual cooperation between the immersion circular pool 507 and the limiting component 505, the surfactant can be automatically and evenly adhered to the surface of the culvert steel cage 2, thereby improving the bonding force between the culvert steel cage 2 and the concrete, and effectively improving the anti-cracking performance of the reinforced concrete culvert; moreover, in this embodiment, by providing an anti-corrosion immersion mechanism 5 and utilizing the mutual cooperation between the rotating bottom plate 508 and the limiting component 505, relative sliding between the culvert steel cage 2 and the movable support leg 406 can be prevented during the lifting process, and the culvert steel cage 2 can be rotated at a uniform speed during the immersion process, thereby improving the uniformity of contact between the culvert steel cage 2 and the surfactant.

A feeding motor for driving the first conveying shaft 602 to rotate is arranged inside the cage conveying platform 601. When the feeding motor is energized, the conveying steel belt 604 will move horizontally.

[0060] According to the above content, after the steel cage is rolled, the staff will place it on the conveyor steel belt 604 in turn. Next, the conveyor steel belt 604 will move slowly under the action of the first conveyor shaft 602, so as to intermittently transport multiple steel cages to the designated position, in preparation for the subsequent immersion and casting processes.
