In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The application provides a maintenance device and a concrete prefabricated part production device with the same.

Example one

As shown in fig. 1 to 5, the curing device of the first embodiment includes a housing 10, a support structure 20, and a driving structure. Wherein the support structure 20 is movably disposed in the housing 10 in a vertical direction and adapted to support the mold table 100. The support structure 20 is plural, and the plural support structures 20 are arranged at intervals in a vertical direction to form the multi-layered curing station 200 within the housing 10. Further, an opening 11 is provided on the housing 10, and each layer of the curing station 200 can circulate the mold table 100 through the opening 11. A drive structure 30 is disposed within the housing 10, the drive structure 30 being adapted to drive simultaneous movement of a plurality of support structures 20, or the drive structure 30 being adapted to drive independent movement of each support structure 20.

With the technical solution of this embodiment, the driving structure 30 can drive the supporting structure 20 to move, so that the mold table 100 on the supporting structure 20 can be circulated between different curing stations 200 in the vertical direction. When the mould platform circulation inefficiency of outside hoisting device, can carry out the inside mould platform circulation of curing means through drive structure 30 to improve curing means's whole circulation efficiency. Therefore, the technical scheme of the embodiment overcomes the defect of low mould platform circulation efficiency of the curing kiln in the prior art.

It should be noted that when the driving structure 30 drives the supporting structure 20 to move upwards or downwards, the mold table 100 supported by the supporting structure 20 can move upwards or downwards synchronously, so that the mold table 100 can flow in the vertical direction inside the curing device.

In this embodiment, the driving structure 30 is used to drive the plurality of support structures 20 to move up or down synchronously. That is, when the driving structure 30 is activated, the mold table 100 located in the curing station 200 of the different layers is simultaneously moved upward or downward.

As shown in fig. 3, in the solution of the present embodiment, the maintenance device further includes a support pillar 40, the support pillar 40 is disposed in the housing 10, and the plurality of support structures 20 are movably disposed on the support pillar 40. Specifically, the bracket posts 40 are column structures extending in the vertical direction, and thus it may be convenient to dispose a plurality of support structures 20 at intervals in the vertical direction. Of course, the support structure 20 may be disposed in other manners, for example, the support structure 20 is disposed directly on the inner side wall of the housing 10, which is also a feasible embodiment

As shown in fig. 3, the bracket post 40 is provided with a sliding groove 41 extending in a vertical direction, and the support structure 20 is disposed in the sliding groove 41. Specifically, since the slide groove 41 extends in the vertical direction, the support structure 20 can be moved in the vertical direction along the extending direction of the slide groove 41. Preferably, since the plurality of support structures 20 move in synchronization in the vertical direction in the present embodiment, it is sufficient to dispose the plurality of support structures 20 in the same chute 41. As can also be seen from fig. 3, the length of the slide groove 41 is long, so that a plurality of support structures 20 can be arranged in the same slide groove 41 at intervals in the vertical direction.

As shown in fig. 1, in the technical solution of the present embodiment, there are a plurality of support columns 40, and each support column 40 is provided with a plurality of support structures 20, so that the mold table 100 in each layer of curing station 200 is supported by a plurality of support structures 20, wherein the support structures 20 located in the same layer of curing station 200 move synchronously. Specifically, since the support structure 20 in the present embodiment has a small volume, in order to ensure that the mold table 100 can be stably supported, a plurality of support structures 20 need to be provided in each layer of the curing station 200. As can be seen from fig. 1, the rack post 40 is provided in plurality in the horizontal direction, and a plurality of support structures 20 are provided on each rack post 40. Further, the number of the supporting structures 20 on each of the supporting columns 40 is the same, and the supporting structures 20 on the plurality of supporting columns 40 are arranged at the same vertical position, so that the plurality of supporting structures 20 form a horizontal supporting plane in the same layer of curing station 200.

For example, in fig. 3, one side of the support column 40 is provided with 7 support structures 20, and thus the 7 support structures form 7 maintenance stations 200. Meanwhile, 4 support columns 40 are shown in fig. 1, each support column 40 is provided with 7 support structures 20, and the arrangement manner of the 7 support structures 20 on each support column 40 is the same (actually, support columns 40 are provided on both sides in the casing 10 (see the content in fig. 14), so that in this embodiment, 8 support columns 40 are provided in the casing 10, and therefore, the support points of the support structures 20 in the same layer of maintenance station 200 form a plane, and the mold table 100 is ensured to be in a horizontal position.

Further, when the driving structure 30 drives the supporting structure 20 to ascend or descend, the supporting structure 20 in the same layer of the curing station 200 ascends or descends synchronously among the plurality of support columns 40, so that the mold table 100 can keep ascending or descending smoothly.

As shown in fig. 4, in the solution of the present embodiment, the driving structure 30 includes two sprockets 31, a chain 32 and a driving element. Wherein, two sprockets 31 are arranged relatively, and chain 32 sets up on two sprockets 31, and bearing structure 20 sets up on chain 32, and drive sprocket 31 rotates. Specifically, the driving structure 30 is disposed in the support column 40, one end of the supporting structure 20 is disposed in the sliding slot 41 and connected to the chain 32, and the other end protrudes from the sliding slot 41 and is adapted to support the mold table 100. The driving member is preferably a motor, which can drive one of the two chain wheels 31 to rotate, and further drive the chain 32 to move, and the chain 32 can drive the supporting structure 20 to move in the chute 41 in the vertical direction when moving. Further, since the length of the chain 32 is long, a plurality of sprockets may be provided at intervals between the two sprockets 31 to secure the chain 32 in tension.

Further, it will be understood by those skilled in the art that the raising or lowering of the support structure 20 may be controlled by controlling the forward and reverse rotation of the motor.

As shown in fig. 4, the supporting structures 20 in this embodiment are disposed on the same sprocket 31 at intervals in the vertical direction, so that when the driving sprocket 31 rotates, the supporting structures 20 can be driven to ascend or descend synchronously.

Of course, the driving structure 30 is not limited to the chain and sprocket structure, and other conventional linear driving structures can be used as the driving structure 30, such as a driving cylinder, an electric push rod, a lead screw and nut mechanism, etc.

As shown in fig. 5, in the solution of the present embodiment, the upper surface of the supporting structure 20 is provided with a sliding structure 70. Specifically, the sliding structure 70 is a pulley, and the sliding structure 70 facilitates the circulation of the mold table 100 to slide the mold table 100 from the support structure 20 into the external lifting device. Further, the pulley may be a powered structure, and further may drive the die table 100 to circulate. Or the rollers are unpowered, and the die table 100 is driven by an external traction device (or the die table 100 is self-powered).

As shown in fig. 2, in the technical solution of this embodiment, a plurality of kilns 12 are disposed at the opening 11, and the kilns 12 and the multi-layer maintenance stations 200 are disposed in a one-to-one correspondence manner. Specifically, the kiln door 12 is closed during maintenance. When the mold table 100 of a certain layer of maintenance station 200 needs to be circulated, the kiln door 12 corresponding to the layer of maintenance station 200 is opened, the mold table 100 is circulated out (or circulated into) the maintenance station, and then the kiln door 12 corresponding to the layer of maintenance station 200 is closed.

Example two

As shown in fig. 6 and 7, the curing device of the second embodiment is different from the first embodiment in that a plurality of slide grooves 41 are provided, and a plurality of support structures 20 and a plurality of slide grooves 41 are provided in one-to-one correspondence. And the driving structure 30 is provided in plurality, and the plurality of driving structures 30 and the plurality of supporting structures 20 are arranged in one-to-one correspondence to drive each supporting structure 20 to move independently.

In the second embodiment, each support structure 20 of the plurality of support structures 20 is independently movable, so that the mold table 100 in a certain layer of the curing station 200 can be independently vertically circulated. Specifically, the maintenance device in the first embodiment has a certain limit when the pallet 100 is vertically circulated. Since the plurality of support structures 20 are raised or lowered in synchronization in the vertical direction in the first embodiment, if the mold table 100 is present in the uppermost curing station 200, the entire circulation system cannot perform upward circulation any more. Similarly, if there is a mold table 100 in the lowermost curing station 200, the entire circulation system cannot perform downward circulation any more. In the second embodiment, as long as the adjacent curing stations 200 corresponding to a certain mold table 100 have empty positions, the mold table 100 can be vertically circulated upwards or downwards independently, and the flow flexibility is greatly improved compared with that of the first embodiment.

As shown in fig. 6 and 7, in the solution of the present embodiment, the adjacent support structures 20 are arranged offset in the horizontal direction, and the movement tracks of the adjacent support structures 20 have an overlapping portion 50 in the vertical direction. Specifically, since the support structure 20 is disposed in the chute 41, the movement locus of the support structure 20 is actually the locus of the chute 41. As shown in fig. 7, a plurality of sliding grooves 41 are disposed on the support column 40, a plurality of supporting structures 20 are disposed in the sliding grooves 41 in a one-to-one correspondence manner, and each sliding groove 41 corresponds to one set of driving structures 30, so as to drive the supporting structures 20 in the sliding groove 41 to move independently.

Further, as can be seen in fig. 7, the adjacent sliding grooves 41 are arranged in a staggered manner, and a part of the adjacent sliding grooves 41 in the vertical direction is overlapped, that is, an overlapped portion 50 is formed. It will be appreciated by those skilled in the art that the intermediate runners 41 have the above-described overlapping portions 50 at both the upper and lower ends, except for the uppermost and lowermost runners 41.

Through the structure, by taking the adjacent two layers of maintenance stations 200 as an example, the supporting structure 20 of the lower layer of maintenance station can move into the upper layer of maintenance station, so that the mold table 100 is supported by the supporting structure 20 in the lower layer of maintenance station and is changed into the supporting structure 20 in the upper layer of maintenance station, and upward circulation of the mold table 100 is realized. Similarly, the supporting structure 20 of the upper curing station can move to the lower curing station, so that the mold table 100 is supported by the supporting structure 20 in the upper curing station and is changed into a supporting structure 20 in the lower curing station, the downward circulation of the mold table 100 is realized, and the downward circulation of the mold table 100 is realized.

Preferably, the support structure 20 has a support position adapted to support the mold table 100, and a retracted position to avoid the mold table 100. Specifically, the support structure 20 is configured as a telescopic structure, thereby preventing the support structure 20 and the mold 100 from interfering when the mold 100 is circulated.

When the table 100 is circulated upwardly, the lower support structure 20 moves upwardly and the upper support structure 20 is in the retracted position with the table 100 passing over the upper support structure 20 and above the upper support structure 20. The upper support structure 20 is then in the support position and the lower support structure 20 is moved downwardly to the home position, so that the mold table 100 is supported by the lower support structure 20 to be changed to be supported by the upper support structure 20, thereby achieving the upward circulation of the mold table 100.

When the downward flow of the mold table 100 is performed, the lower support structure 20 moves upward and supports the mold table 100 located above, and then the upper support structure 20 is in the retracted position. The lower support structure 20 is now moved downwardly and can pass over the upper support structure 20 in the retracted position and bring the die table 100 downwardly. When the lower support structure 20 is moved to the home position, the upper support structure 20 is in the support position, thereby completing the downward flow of the mold table 100.

Further, the telescoping configuration of support structure 20 may be accomplished in a variety of ways, for example, support structure 20 may itself be a nested configuration and may be extended or retracted. Alternatively, the support structure 20 may be extendable or retractable relative to the support post 40 described above.

Therefore, by combining the above-mentioned position arrangement of the sliding grooves 41 and the design of the telescopic structure of the supporting structure 20, the single mold table 100 can be circulated upwards or downwards, and the circulation flexibility is greatly improved.

EXAMPLE III

As shown in fig. 8 to 11, the curing device of the third embodiment is different from the curing device of the second embodiment in that the support structure 20 of the curing device of the third embodiment is used for making an upward circulation to the mold table 100, and the movement of the support structure 20 between the support position and the retracted position is realized by a mechanical structure without additionally providing a driving part.

As shown in fig. 12 and 13, in the solution of the present embodiment, a guide slot 411 is provided on a side wall of the sliding slot 41 of the support post 40. The supporting structure 20 comprises a sliding block 21 and a supporting block 22 arranged on the sliding block 21, the sliding block 21 is arranged in the sliding groove 41, the driving structure 30 is suitable for driving the sliding block 21 to move in the sliding groove 41, a guide block 23 is arranged on the side of the sliding block 21, and the guide block 23 is embedded in the guide groove 411. Specifically, when the sprocket 31 rotates, the chain 32 can drive the sliding block 21 to slide in the sliding slot 41, and the guide slot 411 and the guide block 23 play a guiding role, so that the sliding block 21 can slide smoothly in the sliding slot 41.

Further, as can be seen in fig. 8, the number of the guide blocks 23 is four, two of the guide blocks 23 are disposed on one side of the slider 21, and the other two guide blocks 23 are disposed on the other side of the slider 21. Guide grooves 411 are provided on both side edges of the slide groove 41, two guide blocks 23 of one side of the slider 21 are provided in one guide groove 411, and two guide blocks 23 of the other side of the slider 21 are provided in the other guide groove 411.

The four guide blocks 23 can ensure that the slider 21 does not twist or turn when moving up and down, and further ensure that the position of the support block 22 is stable, so that the die table 100 can be stably supported.

As shown in fig. 8 to 11, in the solution of the present embodiment, the supporting block 22 is pivotally disposed on the slider 21, when the supporting block 22 swings to the horizontal position, the supporting structure 20 is at the supporting position, and when the supporting block 22 swings upward to the vertical position, the supporting structure 20 is at the retracted position. Wherein, the supporting block 22 is provided with a stop surface 221, the stop surface 221 is suitable for abutting against the outer surface of the slider 21 to limit the downward swing of the supporting block 22, the supporting structure 20 further comprises an elastic restoring member 24, and the elastic restoring member 24 applies an elastic force to the supporting block 22 from the vertical position to the horizontal position.

Specifically, the slider 21 is provided with an accommodating recess, and the support block 22 is rotatably provided in the accommodating recess through a rotation shaft. The position of the supporting block 22 where the rotating shaft is provided with the above-mentioned stop surface 221, and when the supporting block 22 swings to the horizontal position, the stop surface 221 is in abutting contact with the outer surface of the slider 21, so that the supporting block 22 cannot swing downward. The elastic restoring member 24 is a torsion spring provided at the rotating shaft, and the torsion spring applies an outward elastic force to the supporting block 22, that is, the supporting block 22 has a tendency to move from the vertical position toward the horizontal position.

It will be understood by those skilled in the art that the support block 22 can swing upward into the receiving space when the lower end of the support block 22 is pushed upward. When the pushing force below the supporting block 22 is removed, the elastic restoring member 24 automatically restores the supporting block 22 to the horizontal position. Meanwhile, the stopper surface 221 allows the supporting block 22 to be maintained in a horizontal position, thereby supporting the die table 100.

Preferably, the lower surface of the supporting block 22 is a wedge surface, so that the lower end of the supporting block 22 can swing upwards more smoothly when being stressed.

Preferably, the sliding structure 70 is disposed on the upper surface of the supporting block 22.

With reference to the above, the following describes in detail the step of the curing device of the third embodiment of upwardly circulating the mold table 100:

for convenience of explanation, in fig. 14, the structure denoted by 20 at the top is designated as the upper support structure 20, and the structure denoted by 20 at the bottom is designated as the lower support structure 20. The upward flow of the mold table 100 is the upward flow of the mold table 100 from the lower support structure 20 to the upper support structure 20.

The method comprises the following steps: as shown in fig. 14, the lower support structure 20 moves upward, thereby moving the mold table 100 upward;

step two: as shown in fig. 15, when the die table 100 moves into contact with the lower surface of the upper support structure 20, the die table 100 pushes the support blocks 22 of the upper support structure 20 upward and swings them to a vertical position, at which time the die table 100 continues to move upward to pass through the upper support structure 20.

Step three: as shown in fig. 16, when the die table 100 moves to be separated from the upper support structure 20, the supporting block 22 of the upper support structure 20 is restored to the horizontal position by the elastic restoring member 24. At this time, the lower support structure 20 is lowered, and the mold table 100 is supported by the lower support structure 20 and is changed to be supported by the upper support structure 20.

Example four

As shown in fig. 17 to 21, the curing device of the fourth embodiment is different from the curing device of the third embodiment in that the support structure 20 is used for downward circulation of the mold table 100, and the structure of the support structure 20 and the structure of the chute 41 are different.

Specifically, as shown in fig. 17 to 19, the guide block 23 includes a first guide block 231 and a second guide block 232, the first guide block 231 is located above the second guide block 232, the guide slot 411 includes a vertical section 4111 and a bending section 4112 arranged below the vertical section 4111, and the bending section 4112 bends toward the outside, wherein when the first guide block 231 and the second guide block 232 are both located in the vertical section 4111, the support structure 20 is in the support position, and when the slider 21 slides downward and makes the second guide block 232 located in the bending section 4112, the slider 21 swings inward, so that the support structure 20 is in the retracted position.

Note that the above-mentioned "bending the bending section 4112 outward" means that the bending section 4112 is bent outward with respect to the housing 10. In other words, if the mold table 100 is provided in the maintenance station 200, the outward bending means bending in a direction away from the mold table 100.

In the fourth embodiment, the supporting block 22 is fixedly disposed on the slider 21. The movement of the support structure 20 between the support position and the retracted position is achieved by a downward oscillation of the slider 21. The contents of fig. 20 and 21 are combined. If the first guide block 231 and the second guide block 232 are both located in the vertical section 4111, the slider 21 will maintain a vertical position, i.e. the support block 22 maintains a horizontal position, and the support structure 20 is in a support position. When the driving mechanism 30 drives the slider 21 to move downward and the second guiding block 232 moves into the bending section 4112, the lower end of the slider 21 tilts inward, so that the supporting block 22 swings inward, and the supporting mechanism 20 is in the retracted position and can be retracted from the die table 100. It will be appreciated by those skilled in the art that if the slider 21 is moved further upwardly, the support structure 20 can now be returned from the retracted position to the support position.

Preferably, the bending section 4112 is an arc-shaped section. Of course, the bending section 4112 may also be a straight line section.

Further, since the driving structure 30 includes the chain 32, in order to prevent the slider 21 and the supporting block 22 from interfering with the chain 32 when swinging downward, in the embodiment, the slider 21 and the supporting block 22 are composed of two side plates connected by a connecting plate, and a cavity is formed between the two side plates. Therefore, when the slider 21 and the supporting block 22 swing downward, the chain 32 can be placed in the cavity, thereby preventing the structural interference.

As shown in fig. 17 and 19, in the solution of the present embodiment, the supporting structure 20 further includes a rotating shaft 25, the sliding block 21 is rotatably disposed on the rotating shaft 25, and the first guiding blocks 231 are disposed at two ends of the rotating shaft 25. Above-mentioned structure can make slider 21 and supporting shoe 22 can swing for pivot 25, therefore when second guide block 232 moves to bend segment 4112, slider 21 and supporting shoe 22 can swing around pivot 25, and then make inward swing motion more smooth, prevent that the structure from blocking.

With the above, the following describes in detail the procedure of the fourth embodiment in which the curing device performs downward flow on the mold table 100:

for convenience of explanation, in fig. 22, the structure indicated by the upper reference numeral 20 is an upper support structure 20, and the structure indicated by the lower reference numeral 20 is a lower support structure 20. The downward flow of the mold table 100 is the upward flow of the mold table 100 from the upper support structure 20 to the lower support structure 20.

The method comprises the following steps: as shown in fig. 22, the lower support structure 20 moves upward and above the upper support structure 20, so that the mold table 100 is supported by the lower support structure 20;

step two: as shown in fig. 23, the upper support structure 20 is moved downwardly, thereby bringing the lower support structure 20 to the retracted position;

step three: as shown in fig. 24, the lower support structure 20 is moved downwardly, and since the upper support structure 20 is now in the retracted position, the mold table 100 can be moved downwardly past the upper support structure 20 and into the lower maintenance station 200;

step four: as shown in fig. 25, the upper support structure 20 moves upwardly and moves the upper support structure 20 from the retracted position to the support position. At this time, the mold table 100 is completely supported by the upper support structure 20 and changed to be supported by the lower support structure 20.

It should be noted that, although the curing device in the third embodiment can only achieve the upward flow of the mold table 100, and the curing device in the fourth embodiment can only achieve the downward flow of the mold table 100, in the two embodiments, the support structure 20 can achieve the transition between the retracted position and the support position through a mechanical structure, no additional driving member is needed, and the production cost is low. When the support structure 20 is freely retractable by the additional driving member, the upward or downward circulation of the single mold table 100 is realized as described in the second embodiment.

As shown in fig. 26, an embodiment of a concrete precast element production line according to the present invention includes the above-described curing device. A lifting device 300 is further included, the lifting device 300 being arranged outside the curing device and corresponding to the opening 11. Specifically, the lifting device 300 may effect the circulation of the mold table 100 outside the curing device, and the support structure 20 and the driving structure 30 inside the curing device may effect the circulation of the mold table 100 inside the curing device. Therefore, when the circulation efficiency of the lifting device 300 is low, the circulation inside the curing device can be activated, thereby improving the overall circulation efficiency of the mold stage 100.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And obvious variations or modifications therefrom are within the scope of the invention.
