Technical Field

An automatic demoulding device for a concrete prefabricated part.

Background

The concrete prefabricated member is also called PC member, and refers to a concrete product produced by standardized and mechanized processing in a factory. The corresponding traditional cast-in-place concrete needs site moulding, site pouring and site maintenance. The concrete prefabricated member is widely applied to the fields of buildings, traffic, water conservancy and the like, and plays an important role in national economy.

In order to provide a height difference for the prefabricated part to be separated from the mould after demoulding, the front surface of the mould is provided with discontinuous bulges. When the mold is demolded in a vibrating mode, the mold is reversely buckled on the vibrating table, upward impact force can be transmitted to the precast block only through the small-area bulges, and the impact effect is weakened through the structure. In the actual production process, the individual demoulding is not successful, and workers need to take the mould with the residual prefabricated parts out of the production line at the next station and manually knock the mould to release.

An automatic concrete preform demolding device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

Referring to fig. 1, the automatic demolding device for the concrete prefabricated member according to the embodiment of the invention comprises a support, a vibration mechanism, a pressing member 1 and a lifting mechanism.

The support can provide a mounting platform for other components of the automatic demoulding device for the concrete prefabricated member, such as a vibration mechanism.

The vibration mechanism is used for providing impact force from top to bottom for the die 2 which is positioned at the demolding station and has a downward opening. Because 2 left-hand threads of mould arrange, the opening arranges down promptly, and its direct action is in the bottom surface of mould 2 when vibration mechanism provides the impact force from top to bottom to mould 2, and the concrete prefabricated part in mould 2 is conducted to the impact force through 2 bottoms of mould by a large scale to guarantee membrane mould effect, membrane mould efficiency.

In this embodiment, the vibration mechanism includes a vibration motor 3 and an impact platform 4, and the vibration motor 3 is fixedly mounted on the impact platform 4, for example, fixed on the impact platform 4 by bolts, but may also be mounted on the impact platform 4 by other fixing methods. The impact platform 4 may be a rectangular steel plate, and preferably, the vibration motor 3 is installed in the middle of the impact platform 4, so that the impact force can be relatively uniformly transmitted to one or more molds 2 with downward openings through the impact platform 4.

Specifically, the support comprises two horizontal beam bodies 5 which are arranged oppositely, a plurality of sub-supports 6 which are erected between the two horizontal beam bodies 5 and are fixedly connected with the corresponding horizontal beam bodies 5 at two sides respectively, and the sub-supports 6 are sequentially arranged along the moving direction of the die 2. The number of the vibration mechanisms is the same as that of the sub-supports 6, and each vibration mechanism is hung on the corresponding sub-support 6 through a connecting piece 7 and can move in the vertical direction relative to the supports. Therefore, the multiple groups of dies 2 can be simultaneously demoulded at the demoulding station, and the working efficiency is improved.

In one embodiment, the connecting member 7 is a bolt, the impact platform 4 and the sub-bracket 6 are both provided with a through hole for a screw of the bolt to pass through, the head of the bolt supports the impact platform 4, and the screw is hung on the sub-bracket 6 through a nut, so that the vibration mechanism is hung on the sub-bracket 6. For the same vibration mechanism, a plurality of connecting pieces 7 can be adopted to hoist the vibration mechanism to the sub-bracket 6 according to the size of the impact platform 4, the power of the vibration motor 3 and the like, and the number of the connecting pieces 7 is not limited in the embodiment. Preferably, the middle part of the sub-bracket 6 is rectangular frame-shaped, and a space for the vibration motor 3 to move in the vertical direction can be provided, so that the space occupied by the automatic demoulding device for the concrete prefabricated member is saved. It should be understood that the bracket and the connecting member 7 may also adopt other suitable structures, which are not listed here.

The size of the mould and the concrete prefabricated part can be changed at different temperatures, the same vibration frequency of the vibration mechanism has different demoulding effects at different temperatures, and the demoulding effect difference is more obvious particularly for areas with larger temperature difference. To solve this problem, it is preferable that the vibration mechanism further includes a frequency converter (not shown in the figure) for changing the frequency of the working power supply of the vibration motor 3, so that the vibration motor 3 can generate correspondingly suitable vibration frequencies at different temperatures to ensure the demolding effect.

The pressing member 1 is used for urging the vibration mechanism to press down on the mold 2 even if the vibration platform can be tightly attached to the bottom surface of the mold 2. In this embodiment, the pressing member 1 is a spring, which is sleeved on the connecting member 7, and two ends of the spring are respectively abutted against the impact platform 4 and the bracket. Because the spring has the energy storage effect, it can absorb the kinetic energy of shaking platform rebound to release energy when shaking platform rebound, thereby further improve the impact force to mould 2, and then improve drawing of patterns effect. Of course, the compression element 1 may take on other suitable configurations, not listed herein.

The lifting mechanism is used for lifting and lowering the support, when the mould 2 with the concrete prefabricated part needs to enter or leave the demoulding station, the lifting mechanism lifts the support, the support drives the vibration mechanism to be lifted synchronously, a set height gap is reserved between the vibration mechanism and the mould 2, if a 1cm height gap is reserved, then the mould 2 can smoothly enter or leave the demoulding station. When the mould 2 needs to be demoulded, the lifting mechanism lowers the bracket to enable the vibration mechanism to be tightly pressed on the mould 2.

In this embodiment, the lifting mechanism is composed of a plurality of cylinders 8, and one end of a piston rod of each cylinder 8 is fixedly connected with the support, specifically, the bottom of the horizontal beam body 5. When the piston rod of the air cylinder 8 extends outwards, the height of the support is increased, and when the piston rod of the air cylinder 8 retracts inwards, the height of the support is reduced. The number and arrangement of the cylinders 8 can be determined according to the load and the support structure, and the number and arrangement of the cylinders 8 are not limited in this embodiment. It should be understood that the lifting mechanism may also be of other suitable configurations, not listed here.

In this embodiment, the automatic demolding device for concrete prefabricated parts further comprises a conveying mechanism 9, wherein the conveying mechanism 9 is used for promoting the mold 2 to move to the demolding station and leave the demolding station. The conveying mechanism 9 may be a conveyor belt, and a driving mechanism, such as a motor, for driving the conveyor belt to operate, but other suitable structures may also be adopted.

Referring now to fig. 2, in another embodiment, the automatic demolding apparatus for concrete prefabricated parts further comprises a first turnover mechanism 10, wherein the first turnover mechanism 10 is used for turning the mold 2 with the upward opening into the downward opening, i.e. reversely arranging the mold 2, and conveying the mold 2 to the conveying mechanism 9.

Specifically, as shown in fig. 4, the first turnover mechanism 10 includes two first horizontal conveyor belts 11 and a second horizontal conveyor belt 12 which are arranged opposite to each other, and a driving mechanism (not shown in the figure) for driving the first horizontal conveyor belts 11 and the second horizontal conveyor belts 12 to operate, where the first horizontal conveyor belts 11 and the second horizontal conveyor belts 12 operate at the same speed, and cooperate with each other to clamp the mold 2 and convey the mold 2 to the conveying mechanism 9. The first turnover mechanism 10 further includes a first rotary table 13 connected to the material input end of the first horizontal conveyor belt 11 and the material input end of the second horizontal conveyor belt 12, a second rotary table 14 connected to the material output end of the first horizontal conveyor belt 11 and the material output end of the second horizontal conveyor belt 12, and a driving mechanism (not shown) for driving the first rotary table 13 and the second rotary table 14 to rotate synchronously.

After the concrete prefabricated member is poured and molded in the mold 2, the concrete prefabricated member enters a first turnover mechanism 10, is driven by a first horizontal conveying belt 11 and a second horizontal conveying belt 12 to be conveyed forwards, and meanwhile, a first rotating disc 13 and a second rotating disc 14 rotate 180 degrees, so that the mold 2 is also rotated 180 degrees under the clamping of the first horizontal conveying belt 11 and the second horizontal conveying belt 12, and then the first turnover mechanism 10 turns over the mold 2 with the opening arranged upwards to arrange the opening downwards and conveys the opening to a conveying mechanism 9. It should be understood that the first flipping mechanism 10 may also have other suitable configurations, not listed herein.

Returning now to fig. 2, in this embodiment, the automatic demolding apparatus for concrete preforms further comprises a mold recovery mechanism 15, and the mold recovery mechanism 15 is used for moving the mold 2 leaving the demolding station to the recovery station. As shown in fig. 5, the mold recovery mechanism 15 includes a robot arm 16, and a pickup device 17, such as a gripper, a suction cup, or the like, mounted to the robot arm 16, the pickup device 17 being capable of picking up and releasing the mold 2.

So as to be convenient for follow-up maintenance, finished product stacking and the like of the concrete prefabricated member.

Since the second turnover mechanism 18 has the same structure as the first turnover mechanism 10 in this embodiment, the detailed structure of the second turnover mechanism 18 will not be described in detail. It should be understood that the second flipping mechanism 18 may also have other suitable configurations, not listed herein.
