Existing demolding devices generally use robotic arms to complete the picking and placing of concrete components. However, the manufacturing cost of robotic arms is relatively high, and concrete components such as shutters are generally heavy and long. It is not easy to maintain stability during the picking and placing process of conventional robotic arms.

[0003] Therefore, it is necessary to provide an improved technical solution for the deficiencies of the above-mentioned existing technologies. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0022] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0023] As Figure 1-2 shown, a demolding machine for concrete components, especially suitable for the production process of the shutter 11, includes a demolding track, a demolding frame 1 and a main frame 2. The main frame 2 is a square frame. One end of the demolding track extends to the outlet of the steam curing kiln, and the other end extends to the mold closing station. A demolding station is provided on the extension path of the demolding track. The demolding station disassembles the top plate and side plates of the mold through a robotic arm, and then the shutter 11 can be taken and placed. After the taking and placing are completed, the mold rotates downward for cleaning and mold closing, and then the next pouring is carried out. A transfer platform 6 is provided on the side of the demolding station. The demolding frame 1 straddles above the demolding station and the transfer platform 6, so that it can move freely between the two after taking and placing the shutter 11.

[0024] The main frame 2 is slidably assembled on the demolding frame 1 to reciprocate along the demolding frame 1 between the demolding station and the transfer platform 6, so as to transfer the shutter 11 from the mold to the transfer platform 6 after taking it out. In the prior art, two shutters 11 are cast simultaneously in the same shutter 11 mold. Two sets of demolding trusses are provided on the main frame 2, so that the two shutters 11 in the same mold can be taken and placed.

[0025] The main frame 2 is provided with a lifting rod 4. The lifting rod 4 can be an oil cylinder, and its lower end is connected to the demolding truss. The lifting rod 4 can longitudinally expand and contract to drive the demolding truss. A plug 5 is provided below the demolding truss. Embedded steel bars 10 are provided on the shutter 11. The embedded steel bars 10 are used for connection with the bridge deck pouring. Both ends of the embedded steel bars 10 are poured into the concrete, so that a plurality of structures similar to handles can be formed. The plug 5 is adapted to the length of the concrete member and corresponds to the plug 5 adapted to the embedded steel bars 10 above the concrete member, thus forming a fork tooth similar to that of a forklift. One end of the upper surface of the plug 5 away from the transfer platform 6 is inclined downward, and the inclination surface ensures that the shutter 11 is not easily detached, ensuring the stability during the picking and placing process.

[0026] In this embodiment, the demolding frame 1 includes two gantry frames distributed at intervals, thereby forming an operation channel corresponding to the main frame 2 in the middle. Transverse movement tracks are provided on both sides of the demolding frame 1 corresponding to the operation channel. The transverse movement tracks can be fixed to the demolding frame 1 in the form of welding or bolts.

[0027] The main frame 2 is provided with transverse movement wheels corresponding to the transverse movement tracks. The transverse movement wheels are correspondingly connected with drive motors, so as to drive the main frame 2 to move along the transverse movement tracks through the drive motors.

[0028] In an alternative embodiment, a plurality of positioning columns extend downward from the main frame 2. The positioning columns can be square steel. The plurality of positioning columns are circumferentially evenly distributed around the demolding truss. A guide column corresponding to the demolding truss is fixed to the side of the positioning column close to the demolding truss through a connecting seat. The guide column passes through the demolding truss and is slidably assembled with it. A stop plate corresponding to the demolding truss is provided on the side of the positioning column. The stop plate defines the lowest position of the demolding truss. At this position, the plug 5 can just pass through the embedded steel bar 10. First, the main frame 2 moves to the side of the demolding station away from the transfer platform 6, and then controls the lowering to align the plug 5 with the embedded steel bar 10, drives the plug 5 to move towards the transfer platform 6 to achieve insertion, and then can be lifted upward to take out the shutter 11, and then moves to the transfer platform 6 to put down the shutter 11.

[0029] In an alternative embodiment, the plug 5 is a plate-like structure, and one end of it away from the transfer platform 6 is bent upward and fixed to the demolding truss, so that there is a gap between the plug 5 and the demolding truss, which is convenient for the plug 5 to insert into the embedded steel bar 10.

[0030] Based on the fact that two shutters 11 are cast at one time by the current mold, the distance between two sets of demolding trusses is adapted to the distance between the embedded steel bars 10 above two concrete members in the same mold, so that two shutters 11 in the mold can be taken out simultaneously.

[0031] Position sensors corresponding to the main frame 2 are provided at both ends and in the middle of the demolding track, so as to detect the moving position of the main frame 2. Among the position sensors in the middle, one corresponds to the station where the plug-in 5 is inserted into the embedded steel bar 10, one corresponds to the position of the transfer platform 6, and another corresponds to the position where the plug-in 5 exits the embedded steel bar 10 on the transfer platform 6, so as to realize automatic operation. The position sensor can be any one of an infrared sensor, a Hall sensor, and a touch switch.

[0032] In an alternative embodiment, in order to make the layout of the casting mold more reasonable in the prior art, two shutter plates 11 are symmetrically distributed about the mold center line. Therefore, one of the shutter plates 11 needs to be rotated to facilitate subsequent maintenance and storage. In order to facilitate subsequent handling, one of the transfer platforms 6 is fixedly supported by support legs below; the other transfer platform 6 is rotatably connected to a support frame 9 below. The support frame 9 can be a square truss. A rotary driving member 16 corresponding to the rotating platform is provided inside the support frame 9. The rotary driving member 16 can be a driving motor. A moving wheel 18 is provided at the bottom of the support frame 9. The moving wheel 18 is correspondingly connected to a driving motor. A steel rail 7 corresponding to the moving wheel 18 is laid on the ground, so that the support frame 9 can be rotated away from the fixed transfer platform 6 by the driving wheel, ensuring that there will be no movement interference during the rotation process, and resetting (or moving to a specified position) after the rotation is completed, so that the two shutter plates 11 can be lifted by a forklift at the same time.

[0033] In order to ensure that the shutter plate with an inverted V-shaped or arc-shaped bottom can be stably placed on the transfer platform, on any one of the transfer platforms 6, two cushion plates 8 symmetrically distributed about the center line are provided above the transfer platform 6. There is a gap between the two cushion plates 8. One side of each of the two cushion plates 8 away from each other is hinged above the transfer platform 6 through a support plate 13. The size of the gap is not limited here, as long as it satisfies that there will be no mutual interference during the up and down rotation of the cushion plates 8. Elastic bands are provided on one side of the two cushion plates 8 close to each other. The elastic bands can be made of rubber material, so that the gap between the two cushion plates 8 is elastically connected, and the elastic bands are used for sealing to prevent debris from slipping from between the two cushion plates 8 onto the transfer platform 6.

[0034] A plurality of reset springs 12 that upwardly abut against the cushion plates 8 are evenly distributed on the transfer platform 6. The reset springs 12 are arranged between adjacent wedge-shaped support members 14. The reset springs 12 drive the cushion plates 8 to have an upward rotation tendency through elastic potential energy, so that the two cushion plates 8 are distributed in a roof shape in the state of not placing concrete components, and the fallen concrete debris slides to both sides, so that it is not necessary to frequently clean the tabletop. Elastic bands are provided between the two cushion plates 8 to always keep the gap sealed during the rotation of the cushion plates 8.

[0035] In an alternative embodiment, the support frame 9 is rotatably connected to the transfer platform 6 through a thrust bearing 17. Both ends of the thrust bearing 17 abut against the support frame 9 and the transfer platform 6 respectively. A gear disk 15 coaxially distributed with the thrust bearing 17 is provided below the transfer platform 6. The main shaft of the rotary drive member 16 drives the gear disk 15 through a drive gear, and the transfer platform 6 is driven to rotate through the rotary drive member 16, thereby realizing the turning of the shutter 11.

[0036] In order to improve the support stability of the backing plate 8, a wedge-shaped support member 14 is provided in the middle of the transfer platform 6. The wedge-shaped support member 14 can be in the shape of a plate to support the backing plate 8 below. The upper surface of the wedge-shaped support member 14 is inclined. After the shutter 11 is placed on the backing plate 8, the backing plate 8 is adapted to the shape of the lower surface of the concrete member, thereby ensuring the stability of the shutter 11.

[0037] In this embodiment, the wedge-shaped support member 14 is in the shape of a plate. One end of the wedge-shaped support member 14 corresponding to the support plate 13 is fixedly connected to the inner side of the support plate 13, and the other end extends towards the center line of the transfer platform 6. A plurality of wedge-shaped support members 14 on the same support plate 13 are evenly distributed to support the backing plate 8.

[0038] In an alternative embodiment, the support plate 13 is a strip-shaped plate body adapted to the backing plate 8. The upper edge of the support plate 13 is hinged to the backing plate 8 through a hinge member. The hinge member can be a hinge, and the lower part is fixedly connected to the transfer platform 6 through a connecting ear and a bolt, or can also be fixed by welding.

[0039] The width of the elastic band is adapted to the distance between the two backing plates 8 in the state where no concrete member is placed. The return spring 12 has a large elastic force to meet the requirement that the backing plate 8 can be bulged upward to a roof shape. Both sides of the backing plate 8 are fixed to the backing plate 8 in forms such as gluing and bolt fixing.

[0040] In the above embodiment, the drive motor and the lifting rod 4 are controlled by the same controller. The controller can be a PLC controller.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the pending claims of the present invention.
