Description

Technical Field

[0001] The invention relates to a prefabricated concrete component production device, in particular to a squirrel cage type turnover demoulding machine for small prefabricated components. Background Art

[0002] With the development of prefabricated buildings, precast concrete components (PC components) are increasingly widely used. Small precast components refer to precast concrete components with smaller volumes, which are often used in railway and highway construction.

[0003] During the production process of small prefabricated components, concrete is poured into a cavity mold by a placing machine, and then cured and solidified. After the curing and solidification, the component is taken out of the mold to obtain a finished small prefabricated component. The process of taking a small prefabricated component out of the mold is called demoulding, and the machine that realizes this process is called a demoulding machine.

[0004] The existing flip demoulding machines for precast concrete component production have the following disadvantages: the supporting structure of the flip body (flip plate) is integral, not suitable for on-site installation, and inconvenient to adjust. The flip body (flip plate) is driven by a belt, and the tension of the transmission body driving the flip body (flip plate) is inconvenient to adjust, and the reliability is poor. During the flipping process of the mold, the conveying system is not connected and fixed as a whole, and the conveying system is prone to deformation and dislocation. There is impact during the flipping process, and the vibration effect is weakened. The material connection and conveying after the component falls off smoothly are not achieved, and other equipment needs to be used in coordination with the demoulding machine, which increases the difficulty of coordination between equipment.

[0005] Relevant patent document: CN116674072A discloses a small prefabricated component flipping and demoulding equipment, comprising: an annular frame, which is provided with two groups, each group of the annular frames is coaxially distributed, and the annular frame is provided with an opening for the mold to enter and exit; a frame, which is provided with two groups, which are respectively arranged at the bottom of the two groups of annular frames, and one of the frames in one group is provided with a driving member. In this scheme, the mold is transported from the opening to the equipment through a conveying member, so that the mold is located between the limiting part and the placement plate, so that the mold with the prefabricated part is not thrown out during the flipping process, and the driving member is started. The driving member drives the annular frame to rotate, and the annular frame drives the vibration mechanism to rotate. The vibration mechanism drives the mold flipping degree through the conveying mechanism, so that the conveying mechanism reaches the top, and the vibration component is started. The vibration component drives the moving frame to vibrate up and down, and the vibration force is transmitted to the placement plate, so that each position of the mold can vibrate synchronously, and the mold can be completely demolded. CN222096498U discloses a preform flip demoulding machine, comprising a fixed bracket, characterized in that: a driving motor is connected to the side wall of the fixed bracket, a driving end of the driving motor is connected to a driving rod through a coupling, a driving sprocket is symmetrically connected to the side wall of the driving rod, and a driven sprocket is meshedly connected to the side wall of the driving sprocket through a driving chain. An adjustable clamping structure is provided in the preform flip demoulding machine, so that the rotating motor in the adjustable clamping structure can be adjusted according to the size of the preform through the transmission structure, so that during the use of the preform flip demoulding machine, the clamping position can be adjusted according to the size of the preform, making the device more convenient to use, thereby solving the problem of the non-adjustable clamping position.

At the same time, the upper surface of the vibration beam 306 is in contact with the bottom of the mold A. At this time, the piston rod of the lifting cylinder 304 stops after descending to the position. The two claw assemblies 308 are actuated by the four claw cylinders 3083, driving the hook bodies 30811 of the two claws 3081 in each claw assembly 308 to move inward relative to each other, and the four claws 3081 in the two claw assemblies 308 clamp the mold A to fix the mold A.

[0036] like Figure 1 , Fig. 9 , Fig.10As shown, the structure of the conveying mechanism 4 installed on the upper fixed frame 201 is that the conveying mechanism 4 has four worm gear elevators 402, a transfer case 403, a main motor 404 that drives the driving ends of the four worm gear elevators 402 through the transfer case to make the lifting rod of each worm gear elevator move up and down, and a belt conveyor 401. The bases of the four worm gear elevators 402, the base of the transfer case 403, and the base of the main motor 404 are all fixedly installed on the upper fixed frame 201. The belt conveyor 401 comprises a support frame 4013, a reduction motor 4011, an active roller shaft 4015 installed on the support frame 4013 and arranged horizontally left and right, a driven roller shaft 4012 installed on the support frame and arranged horizontally left and right, a conveyor belt 4014 passing around the active roller shaft 4015 and the driven roller shaft 4012, a driving sprocket 4017 fixedly installed on the power output shaft of the reduction motor 4011, a driven sprocket 4019 fixedly installed on the active roller shaft 4015, and a first chain 4018 connecting the active sprocket 4017 and the driven sprocket 4019. The support frame 4013 is in the shape of a rectangular parallelepiped, and the base of the reduction motor 4011 is fixed on the outer wall of the upper fixed frame 201. Specifically, the base of the reduction motor 4011 is fixed to the mounting plate 4016 by bolts, and the mounting plate 4016 is horizontally arranged and fixed (welded) on the outer wall of the upper fixed frame 201. The active roller shaft 4015 and the driven roller shaft 4012 are both limitedly supported by the support frame 4013. The conveyor belt 4014 is disconnected at the corresponding position of the lifting rod of each of the worm gear elevators 402 and is divided into three sections. The bottom end of the lifting rod of each of the worm gear elevators 402 is fixedly connected to the support frame 4013 (it can be a flange connection), thereby realizing the connection between the worm gear elevator 402 and the belt conveyor 401. In this way, the main motor 404 drives the four worm gear elevators 402 to drive the belt conveyor 401 to achieve synchronous and stable lifting. At the same time, due to the self-locking performance of the worm gear mechanism, the belt conveyor 401 can be stopped at the working position more safely and reliably. The above-mentioned turnover mechanism 2 also has two reinforcing rods 203 that connect the two turnover disks 205 into one. The two reinforcing rods 203 are located between the upper fixed frame 201 and the lower fixed frame 202. The two ends of each reinforcing rod 203 are respectively fixedly connected to the outer edges of the inner side walls of the two turnover disks 205 (can be welded). In this way, the two reinforcing rods 203 are provided to increase the rigidity of the turnover mechanism 2.

[0037] When the present invention is working, when the clamping claw 3081 in the clamping claw assembly 308 clamps the mold A, the mold A is fixed, and the worm gear elevator 402 drives the belt conveyor 401 to descend. After the lower surface of the belt conveyor 401, i.e., the lower surface of the conveyor belt 4014, is lowered to fit the upper surface of the mold A, the worm gear elevator 402 stops running. At this time, the driving motor 204 in the flipping mechanism 2 is started, and the flipping mechanism 2 drives the mold A to flip 180° until the mold A stops in a horizontal position. Then, the vibration motor 305 in the vibration demoulding mechanism 3 is started, and the exciting force of the vibration motor 305 is transmitted to the mold A and the components in the mold A (i.e., the small prefabricated component finished product B, which can be two rows of 14 finished products) through the vibration beam 306. By setting a certain vibration time, until the small prefabricated component finished product B is completely ejected from the mold A, the demoulding process is completed. The exciting force of the vibration motor 305 is adjustable by the frequency converter to meet the needs of various prefabricated component products. During the turning process of the turning mechanism 2, the lower surface of the belt conveyor 401, i.e., the lower surface of the conveyor belt 4014, is in contact with the upper surface of the mold A, which can prevent the component from falling out and causing damage during the turning process. After demoulding is completed, the worm gear elevator 402 brings the belt conveyor 401 and the finished component (i.e., the small prefabricated component finished product B) down to a set height, and the reduction motor 4011 of the belt conveyor 401 is started, and the finished component (i.e., the small prefabricated component finished product B) is transmitted to the stacking station through the conveyor belt 4014, and enters the finished product stacking process. A component monitoring device is installed on the belt conveyor 401. After all the finished components (i.e., the finished small prefabricated components B) are transferred, the reduction motor 4011 of the belt conveyor 401 stops working, the turning mechanism 2 turns the empty mold A by 180° back to the horizontal position of the mold A, the claw 3081 releases the mold A, and then the lifting cylinder 304 is actuated to lift the lifting frame 301, so that the conveying support roller body 302 and the conveying driving wheel 303 are fitted with the mold A together. At this time, the second motor 307 that provides driving force for the conveying driving wheel 303 is started, and the empty mold A is conveyed to the lower station for the empty mold cleaning process, thereby completing the entire turning and demoulding operation of the mold A loaded with the finished small prefabricated component B. During the operation, the mold A loaded with the finished small prefabricated component B enters from the gap 200 on the side wall of the turning disc 205 on the left, and the empty mold A is conveyed out from the gap 200 on the side wall of the turning disc 205 on the right. The inversion demoulding of the present invention is carried out in a cavity formed by two inversion plates 205 and the upper fixing frame 201 and the lower fixing frame 202. The cavity is shaped like a squirrel cage, so it is called a squirrel cage type inversion demoulding machine.

[0038] During the production process, the concrete placing machine pours concrete into the cavity mold A. After curing and solidification, the concrete reaches the demoulding station through the transmission line. The squirrel cage type flip demoulding machine of the present invention flips and demoulds to realize batch automatic demoulding of multiple groups of small prefabricated components. Fig.11As shown, the mold A loaded with the finished small prefabricated component B is moved to the squirrel cage type flip demoulding machine of the present invention via the transmission line along the production line direction (i.e., the conveying direction of the mold A), and the mold A is flipped 180°. The vibration motor 305 of the present invention applies an exciting force to the mold A together with the component to make the component pop out of the mold A, and the finished component is output laterally from the squirrel cage type flip demoulding machine of the present invention to the finished product stacking station. After demoulding, the empty mold A enters the next mold cleaning station along the production line direction, thereby completing the entire process of demoulding the small prefabricated component and achieving the purpose of batch automatic demoulding. Fig.11 In the figure, reference numeral C is the invented squirrel cage type flip demoulding machine, reference numeral D is the production line direction, reference numeral A is the mold, wherein the mold A on the left is loaded with a small prefabricated component finished product B, the mold A on the left is an empty mold, and reference numeral E is the finished product stacking station.

[0039] Compared with the technical solution disclosed in CN116674072A (reference document 1) in the background technology, the present invention is essentially different therefrom, and the specific differences are as follows: 1. The supporting structure of the flip plate is different. The present invention is a support seat structure, which is flexible to install on site and convenient to level. Comparative Document 1 is two sets of integral supports, which are inconvenient to adjust.

[0040] 2. The driving modes of the flipping disk are different. The present invention is driven by a chain to flip, while the comparative document 1 is driven by a belt. The present invention adopts a combination of a chain and a tensioning seat, which are connected and fixed with a pin, a pull rod, and a lock nut. The operation is safer and more reliable, the tensioning seat is easy to adjust, the transmission body tension (chain tension) of the driving flipping disk is easy to adjust, the chain transmits force more directly, and the driving of the flipping disk is smoother.

[0041] 3. The conveying systems for the mold from entering to exiting are different. Comparative Document 1 is a chain conveyor, while the present invention is a support wheel system driven conveyor (a combination of a conveying support roller body and a conveying driving wheel). During the flipping process, the support wheel system frame (a combination of a lifting frame body, a conveying support roller body, and a conveying driving wheel) is connected and fixed as a whole, which is safe and reliable. However, the chain (bar) conveying method is prone to deformation and dislocation during the flipping process.

[0042] 4. The fixing method of the mold before flipping is different. The present invention uses a claw cylinder and a claw to fix the mold, and the rigid fixation is safe and reliable. In addition, a shock-absorbing pad is arranged at the bottom of the mold after it is fixed, which has a good shock-absorbing effect on the supporting device. In the comparative document 1, the mold is located between the limiting part (limiting plate) and the placing part (placing plate), without rigid fixation, and there is impact during the flipping process.

[0043] 5. The arrangement of the vibration motor is different. In the present invention, the mold is rigidly fixed, and the vibration motor is directly transmitted to the bottom of the mold through the vibration beam, so the vibration transmission effect is good. In the comparative document 1, the mold is not fixed after the mold is flipped, and the mold relies on the elastic force of the spring and the vibration motor to work together. The vibration demolding effect depends on the spring adjustment, and the vibration effect is weakened.

[0044] 6. The transportation methods of components after vibration demolding are different. The present invention adopts conveyor belt transportation. Comparative Document 1 sets a mobile vehicle under the equipment. The conveyor belt transportation of the present invention can meet the demolding transportation of various types of components in the mold, and can achieve seamless connection with the mold, so as to truly achieve the smooth removal of components and the material connection and transportation. The mobile vehicle in Comparative Document 1 needs to cooperate with the demolding machine, which increases the difficulty of controlling the coordination between equipment.

[0045] The present invention adopts the technical solution of flipping the mold 180° and demoulding by vibration, which achieves the purpose of demoulding and removing multiple groups of small components in the mold in batches. The whole process is completed automatically, which improves the demoulding efficiency, and also plays a role in reducing labor intensity and improving safety. After the small prefabricated components are demoulded, the finished products are output along the side of the production line and enter the finished product stacking station, while the empty molds enter the empty molds along the production line direction to clean up the empty positions. The layout of the present invention is reasonable, which improves the operating efficiency of the entire production line and realizes the automatic demoulding of small prefabricated components in batches. Compared with the existing related technologies, the operating efficiency of the entire production line in the above embodiments of the present invention is improved by more than 12%.

[0046] In summary, the squirrel cage type flip demoulding machine for small prefabricated components of the present invention has an easily adjustable transmission body tension driving the flip body (flip disk), which achieves the smooth removal of components and the subsequent material connection and transportation, avoids the need for other equipment to cooperate with the demoulding machine, and makes the operation more reliable.
