[0042] The working principle of the above-mentioned prefabricated box beam end formwork rapid removal system is:
[0043] First, when using the device, first place the device in the working area, then connect the device to an external power source to provide the device with the power required for operation, and provide hydraulic energy and air pressure energy to the hydraulic cylinder assembly 454, the pressure mechanical arm 463, the rust removal nozzle 467, the pneumatic clamp 4643 and the mold removal nozzle 4645 through the connecting pipe;
[0044] Second, fix the fixed base 1 at the box beam opening with bolts, reset the winch 2 and the mobile lifting trolley 33, check the working status of each component of the trolley assembly 3 and the demolding assembly 4, and place the sleeve nut 4664 used to fix the end mold support beam on the plug-in rod 4663;
[0045] Third, a wireless connection is established with an external control terminal through the single chip chassis 32, and then the transmission gear 43 is driven to transmit by controlling the first stepper motor 42, so that the transmission gear 43 is meshed with the tooth groove on the side of the steel beam guide rail 44, and then the steel beam guide rail 44 slides in the motor seat 41, and the steel beam guide rail 44 drives the moving vehicle assembly 46 and the tail support assembly 45 to quickly move close to the end mold, and then the self-locking motor 452 drives the first bevel gear set 453 to rotate to adjust the angle of the hydraulic cylinder assembly 454. When the hydraulic cylinder assembly 454 is adjusted to maintain a vertical state with the ground, the multiple groups of hydraulic cylinders in the hydraulic cylinder assembly 454 are driven to extend through the external control terminal, thereby driving the coil bottom plate 455 to contact the ground, and the electromagnetic coil inside the coil bottom plate 455 is energized to generate magnetism and fixedly adsorbed with the steel bars tied to the bottom side of the prefabricated box beam, thereby further improving the supporting effect of the tail support assembly 45;
[0046] Fourth, the load moving vehicle 461 and the pressure mechanical arm 463 in the moving vehicle assembly 46 drive the first mounting frame 465 and the bolt removal assembly 466 to slowly and accurately approach the bolt at the connection between the support screw and the end mold, and the second visual camera 462 is used here for real-time image monitoring, and then the external rust remover is sprayed on the bolt of the support screw through the rust removal nozzle 467 to provide rust removal for the bolt connection to facilitate disassembly, and then the sleeve nut head 4664 in the bolt removal assembly 466 is matched with the bolt, and then the sleeve nut head 4664 is driven by the second stepping motor 4661 to Disassembly; then insert the connecting rods on the front and rear two sets of pressure mechanical arms 463 and the quick-insert assembly 464 on the top side of the load moving vehicle 461 into the screw holes of the support rods, and then the pressure mechanical arms 463 grab the support rods and place them on the turntable assembly 34 on the top side of the mobile lifting trolley 33. Here, the first visual camera 35 is used to detect the placement status of the turntable assembly 34 and the support rods, and then the angle of the support rods is adjusted by the rotation of the turntable assembly 34, and then the mobile lifting trolley 33 is pulled by the winch 2 to drive the turntable assembly 34 and the support rods out of the box beam opening, and the staff removes the support rods through external equipment;
[0047] Fifth, the first stepper motor 42 and the transmission gear 43 drive the steel beam guide rail 44 to further move into the end mold, and the load moving vehicle 461 and the pressure mechanical arm 463 are repeatedly controlled to move and drive the sleeve nut head 4664 to approach the bolts on the bottom side of the end mold. The steps are repeated to make the second stepper motor 4661 and the sleeve nut head 4664 dismantle the bolts of the frame. At this time, the top frame of the end mold changes from the fixed state of the straight state to the M state, and the steps are repeated to grab the frame and place it on the top of the mobile lifting trolley 33 and the turntable assembly 34. Then, according to the same steps, the top side frame of the end mold is disassembled and transported out via the mobile lifting trolley 33. Here, the top and both sides of the end mold are not supported by the frame.
[0048] Sixth, the staff here removes the connecting rod on the quick-insert assembly 464 through the electromagnetic clamp 4642 and replaces it with the pneumatic clamp 4643, and then uses the pneumatic clamp 4643 to slowly peel off the end mold on one side of the box girder with the cooperation of the load moving vehicle 461 and the pressure mechanical arm 463. Here, the reversing valve 4644 ensures that the clamping air pressure of the pneumatic clamp 4643 is stable, and then the gas is guided to the demoulding nozzle 4645. Here, the end mold and concrete are stripped by high-pressure gas to purge, which plays a role in the concrete. The function is to separate the soil surface from the bonding surface of the prefabricated end mold; after determining that the end mold is detached from the concrete surface, the mobile lifting trolley 33 is controlled to move into the box beam, and the lifting action of the mobile lifting trolley 33 is driven to make its lifting platform push up against the right end of the steel beam guide rail 44, and cooperate with the tail support assembly 45 to keep the steel beam guide rail 44 in a high-load horizontal state, and then the end mold is grabbed and transported out by the pressure mechanical arm 463 and the pneumatic clamp 4643 at its end, and then the other side end mold is removed and transported out through the same steps.
[0049] The present invention provides a system for quickly removing the end mold of a prefabricated box beam through improvements. The system arranges a trolley assembly 3 and a mold removal assembly 4 on the top of a fixed base 1, and utilizes the adjustment actions of a fixed lifting trolley 31 and a mobile lifting trolley 33 to cooperate with the semi-automatic disassembly action of the mold removal assembly 4 on each node of the end mold. The hydraulic pressure of a pressure mechanical arm is used to improve the construction efficiency of the end mold, and high-pressure gas purging is also used to assist in separation, which saves time and effort and ensures the safety of construction workers to a great extent. The equipment is simple and convenient to operate, has strong maneuverability, realizes basic universality of the inner mold of the box beam, and greatly improves the efficiency of inner mold assembly and disassembly.
