Description

Technical Field

[0001] The invention relates to the field of concrete pouring, and in particular to an automatic demoulding mechanism for a prefabricated concrete part. Background Art

[0002] When pouring concrete for internal hole-type buildings (septic tanks, pipe wells, bridge piers with internal holes, elevator shafts, etc.), demoulding of the internal holes of the building needs to be completely disassembled, which is cumbersome to construct and difficult to ensure the shape and its precise size when the mold is formed. The demoulding mechanism that can shrink in one piece has poor locking retention force. If there is no self-locking mechanism, it will loosen after a long period of vibration, resulting in a reduction in the molding size. In addition, special fasteners are required to connect the template and the drive mechanism, which have poor versatility and are difficult to fix. In addition, the demoulding shrinkage drive method is single, and demoulding cannot be driven from the inside. Lifting requires the help of external force, which has poor stability. The overhead crane cannot have a large load, and there are strict requirements on the weight of the mechanism itself. Summary of the invention

[0003] In view of the above-mentioned deficiencies, the present invention provides an automatic demoulding mechanism for precast concrete parts.

[0004] The technical solution adopted by the present invention to solve the technical problem is: an automatic demoulding mechanism for precast concrete parts, including a base system, a lifting and ejecting system, a separation drive system, a top cover system and a template system;

[0007] The worm gear mechanism has a self-locking function, which can prevent the automatic rotation of the internal drive worm gear and the bidirectional lead screw, thus playing a self-locking role.

[0008] The base system is used for supporting and adjusting the entire mechanism, the lifting and ejection system cooperates with the base system for lifting and lowering the entire mechanism, the separation drive system and the formwork system are used for inward and outward support of the formwork during demoulding, and the top cover system is used for internal protection and introduction of concrete during pouring.

When internal drive is required, the driving clutch is closed, the main worm wheel engages with the internal driving clutch, the driving clutch engages with the main driving rod, and the main driving rod drives the operation of other components to achieve internal drive.

[0010] Push out the driving clutch and separate it from the main worm gear. The main driving rod can directly drive other components to realize driving from the top. At the same time, closing the inner driving clutch after the driving is completed can also prevent the main driving rod from rotating by itself, thus playing a self-locking role.

[0018] As an optimization, the lifting and escape system adopts a self-climbing hoisting mechanism;

[0019] The self-climbing hoisting mechanism comprises a lifting and ejecting beam and a plurality of multi-stage hydraulic power cylinders arranged at the top of the prefabricated parts. The lifting and ejecting beam passes through the top cover system and is fixedly connected to the template system via a special connecting rod.

[0020] As an optimization, the top cover system includes an outer frame, which is fixedly connected to the formwork system by pins; the cross-section of the outer frame is an isosceles right triangle, which is convenient for introducing concrete.

[0021] As an optimization, the movable plate and the template system are fixed by pins.

[0022] As an optimization, the cross section of the substrate is a right angle or a chamfer.

[0023] The present invention has the following beneficial effects:

[0024] 1. A separate drive system with a dual-drive power mechanism compatible with internal drive and external drive is adopted, which can realize the operation of personnel above the top cover system and also realize the operation of personnel in the operation cavity of the mechanism;

[0025] 2. The separation drive system adopts a worm gear mechanism with a self-locking function to prevent the separation drive system from opening automatically, thereby avoiding the shrinkage system from shrinking inwards, causing the size of the prefabricated part to change;

[0026] 3. The connection between the formwork system and the formwork system, and the connection between the separation drive system and the formwork system are all connected by standard pins, which increases versatility and reduces installation difficulty;

[0027] 4. The lifting and ejection system adopts a rigid and flexible guide mechanism to ensure stability during lifting and prevent the entire mechanism from being scratched and damaged by the prefabricated wall, thereby damaging the wall or the entire mechanism;

[0028] 5. The base system adopts a special support mechanism to ensure the stability of the whole set of support;

[0029] 6. The base system and the lifting and release system adopt a double-insurance support mechanism, which acts as different fulcrums when the system is lifted;

[0075] S2: pouring base concrete, pouring concrete from top to bottom and waiting for the concrete to solidify;

[0076] S3: demoulding, the main worm 311 is driven manually or by a stepper motor, and the main worm 311 drives the main worm wheel 309 to rotate, thereby realizing the rotation of the main driving rod 303, thereby driving the inner driving worm 304 to rotate, and the inner driving worm 304 drives the inner driving worm wheel 305 to rotate; the inner driving worm wheel 305 drives the coaxially arranged bidirectional lead screw 306 to rotate, and the bidirectional lead screw 306 has symmetrical bidirectional positive and negative threads, and the rotation of the positive and negative threads drives the driving nut block 307 to separate or move together at the same time, and when the driving nut block 307 separates, the moving plate 302 separates, and when the driving nut block 307 moves together, the moving plate 302 moves together, and the moving plate 302 moves together to drive the template system 5 to separate from the preform molding surface; at the same time, it drives the base plate 301 to move inward and separate from the preform molding surface, so as to realize the separation of the entire mechanism from the preform molding surface;

[0077] S4: The mechanism as a whole climbs upward. When the self-climbing lifting mechanism is adopted, the first leg 1032 located in the reserved hole groove of the concrete wall is firstly retracted, and then the hydraulic power cylinder 201 is started to make the mechanism as a whole rise, so that the first leg 1032 reaches the position of the next reserved hole groove of the concrete wall, and the first leg 1032 is inserted therein and fixed, and then the pull rope is pulled to make the driving rod 2023 drive the second leg 2024 to be retracted from the reserved hole groove of the concrete wall, and the hydraulic power cylinder 201 is contracted to make the second leg 2024 reach the position of the next reserved hole groove of the concrete wall, and the driving rod 2023 is pressed to make the second leg 2024 inserted therein and fixed;

[0078] When the self-climbing lifting mechanism is used, the first leg 1032 located in the reserved hole groove of the concrete wall is first retracted, and then the hydraulic power cylinder 201 is started to make the mechanism rise as a whole, so that the first leg 1032 reaches the position of the next reserved hole groove of the concrete wall, and the first leg 1032 is inserted into it and fixed, and the multi-stage hydraulic power cylinder 201 is started to drive the lifting of the escape beam 204.
