[0039] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0040] The utility model provides a dismantling stacker and a concrete prefabricated component production line. Figures 1 to 19 , firstly, an embodiment of a destacker is introduced.

[0041] Embodiment 1

[0042] like Figures 1 to 6 As shown, the stacker dismantling machine of the first embodiment includes a frame 1, a transmission device 2 and a lifting device 3 arranged on the frame 1. Specifically, the frame 1 includes two supporting frames 11 arranged opposite to each other, and the two supporting frames 11 are respectively located on both sides of the supported object. A transmission device 2 and a lifting device 3 are arranged on each supporting frame 11. The transmission device 2 includes a transmission wheel and a transmission chain 21, and the transmission wheel is suitable for driving the transmission chain 21 to transmit. The lifting device 3 is connected to the transmission chain 21, and the transmission chain 21 is suitable for driving the lifting device 3 to rise and fall when transmitting. The lifting device 3 has an extended position and a retracted position. When the lifting device 3 is in the extended position, the lifting device 3 is suitable for connecting with the supported object. When the lifting device 3 is in the retracted position, the lifting device 3 is suitable for separating from the supported object.

[0043] In this embodiment, the transmission chain 21 can drive the lifting device 3 to rise and fall when driven by the transmission wheel, so that the lifting device 3 can drive the supported object to rise and fall when in the extended position, so as to achieve stacking or unstacking of the supported object layer by layer from bottom to top, and the unstacking cycle is fast. Moreover, the transmission efficiency of the transmission chain 21 and the transmission wheel is high, which improves the lifting efficiency of the lifting device 3, and the lifting device 3 is connected or separated from the supported object on both sides of the supported object, which reduces the lifting stroke, further improves the efficiency of unstacking, and is convenient for adapting to fast-beat production.

[0044] In a concrete precast component production line, the supported object is usually a formwork table 7 , and the following description will be made assuming that the supported object is the formwork table 7 .

[0045] Each support frame 11 may include a plurality of sub-support frames arranged at intervals, that is, a plurality of sub-support frames are arranged on both sides of the mold platform 7, and each sub-support frame is provided with the above-mentioned transmission device 2 and lifting device 3. For example, Figure 1 As shown, each support frame 11 includes two sub-support frames arranged at an interval, and the four sub-support frames are roughly arranged to form a rectangular structure.

[0046] Furthermore, the stacker dismantling machine further includes a synchronous drive device 4, wherein the transmission wheel includes a driven wheel 23 and a driving wheel 22, and the synchronous drive device 4 is suitable for connecting with the driving wheel 22 of each transmission device 2, and is suitable for driving the driving wheel 22 of each transmission device 2 to rotate synchronously. The transmission chain 21 is constructed as a closed ring structure, and is meshed and matched between the driven wheel 23 and the driving wheel 22. With such a configuration, when the synchronous drive device 4 drives the driving wheel 22 of each transmission device 2 to rotate synchronously, it can drive the driven wheel 23 of each transmission device 2 to rotate synchronously through the transmission chain 21, thereby causing the transmission chain 21 of each transmission device 2 to rotate synchronously, and driving the lifting device 3 connected to the transmission chain 21 to rise and fall synchronously, so as to ensure the stability of the lifting of the mold platform 7.

[0047] Furthermore, each support frame 11 is provided with a plurality of transmission devices 2, which are arranged at intervals along the axial direction of the transmission wheel, and the transmission wheels of the plurality of transmission devices 2 are arranged coaxially and rotate synchronously. The lifting device 3 is connected to the transmission chains 21 of the plurality of transmission devices 2. The plurality of transmission chains 21 jointly drive the lifting device 3 to rise and fall, which can ensure the reliability of the support mold platform 7 and the stability of the lifting and falling of the mold platform 7.

[0048] Specifically, it can be achieved, such as Figure 1-3 Each support frame 11 includes two sub-support frames arranged at intervals, and the four sub-support frames are roughly arranged in a rectangular structure. Two sets of transmission devices 2 and a set of lifting devices 3 are arranged on each sub-support frame, and the lifting devices 3 are connected to the transmission chains 21 of the two sets of transmission devices 2.

[0049] Furthermore, the synchronous drive device 4 includes a drive motor 41 and a plurality of transmission shafts 44. The drive motor 41 may be a reduction motor connected to the plurality of transmission shafts 44 to provide a rotational driving force for the transmission shafts 44. The plurality of transmission shafts 44 are diffusely connected to the driving wheels 22 on the four sub-support frames with the reduction motor as the center position. Figure 1 and 2 As shown, the transmission shaft 44 includes six, six rotating shafts connected and distributed in an "I" shape. Among them, two transmission shafts 44 are provided between the two sub-support frames of each support frame 11, and the two transmission shafts 44 are respectively connected to the driving wheel 22 of the transmission device 2 on one of the support frames 11 to drive the driving wheel 22 to rotate. Among them, two transmission shafts 44 are also provided on the inner sides of the two support frames 11. The driving motor 41 is connected between the two transmission shafts 44 located on the inner sides of the two support frames 11 to realize the linkage of the six transmission shafts 44.

[0050] Exemplarily, a transfer case 42 is further connected between the two transmission shafts 44 between the two sub-support frames of each support frame 11, and a coupling 43 is provided on the transmission shaft 44 connected to the driving wheel 22, and the driving wheel 22 is mounted on the coupling 43. Exemplarily, two sets of transmission devices 2 are provided on each sub-support frame, and the two driving wheels 22 of the two sets of transmission devices 2 are both arranged on the same coupling 43 to achieve coaxial arrangement and synchronous rotation.

[0051] like Figure 1 As shown, the synchronous drive device 4 can be arranged at the bottom of the frame 1, and correspondingly, the driving wheel 22 of each transmission device 2 is also arranged at the bottom of the support frame 11, and the driven wheel 23 is provided at the top of the support frame 11. In some embodiments not shown in the figures, the synchronous drive device 4 can be arranged at the top of the frame 1, and correspondingly, the driving wheel 22 of each transmission device 2 is also arranged at the top of the support frame 11, and the driven wheel 23 is provided at the bottom of the support frame 11.

[0052] Further, such as Figure 4 The lifting device 3 includes a lifting seat 31 and a telescopic member 32. The lifting seat 31 is connected to the transmission chain 21. The telescopic member 32 is telescopically arranged on the lifting seat 31 to facilitate switching between the extended position and the retracted position, which is simple and convenient.

[0053] Specifically, the telescopic member 32 includes a driving structure and a latch 321, and the driving structure is suitable for driving the latch 321 to extend or retract to the inner side of the support frame 11, so as to connect or separate from the mold platform 7. It can be understood that the inner side of the support frame 11 refers to the opposite side between the two support frames 11.

[0054] like Fig.18 and 19 As shown, a support 71 is provided on the side of the die table 7, and the support 71 is composed of a bottom plate 711, a top plate 712, and two side plates 713 connected to both sides of the bottom plate 711 and the top plate 712. The bottom plate 711, the top plate 712, and the two side plates 713 jointly surround a clamping groove. When the driving structure drives the bayonet 321 to extend, the bayonet 321 is inserted into the clamping groove to achieve connection with the die table 7. Among them, the driving structure can adopt a lead screw structure, a linear motor, a cylinder, etc., as long as it can achieve the function of driving the bayonet 321 to extend.

[0055] Furthermore, the stacker dismantling machine further comprises a guide structure, which is arranged between the lifting seat 31 and the support frame 11, and is suitable for guiding the lifting seat 31 to move in the vertical direction to ensure the stability of the lifting device 3 driving the die table 7 to rise and fall. The guide structure comprises a guide rail 113 and a first pulley 311, the guide rail 113 is arranged on the support frame 11, the first pulley 311 is arranged on the lifting seat 31, and the first pulley 311 and the guide rail 113 are in rolling cooperation.

[0056] Specifically, it can be achieved, such as Figure 4 As shown, a slide groove is formed in the sub-support frame along the vertical direction, and the lifting seat 31 is located in the slide groove and rises and falls along the slide groove. The lifting seat 31 is constructed as a square cylindrical structure with a hollow interior, and two transmission chains 21 are arranged in the lifting seat 31 and are fixedly connected to the side walls on both sides of the lifting seat 31. Exemplarily, the sub-support frame may include a first frame body 111 and a second frame body 112 connected to each other, and the above-mentioned slide groove is formed between the first frame body 111 and the second frame body 112.

[0057] In the relative direction of the two support frames 11, both ends of the lifting seat 31 extend out of the sub-support frame, and a plurality of first pulleys 311 are provided at both ends of the lifting seat 31. Accordingly, guide rails 113 extending in the vertical direction are correspondingly provided on both sides of the sub-support frame, and when the lifting seat 31 is lifted and lowered under the drive of the transmission chain 21, the first pulleys 311 roll along the guide rails 113.

[0058] Furthermore, the stacker dismantling machine further comprises a sliding support device 5, which is arranged on the inner side of the two support frames 11 and is suitable for supporting and conveying the die table 7. Figure 1 , two groups of sliding support devices 5 are provided, each of which is arranged adjacent to one of the support frames 11 to support the two sides of the die table 7. Exemplarily, the frame 1 also includes a base 12, and the two support frames 11 are both arranged on the base 12, and the two groups of sliding support devices 5 are also arranged on the base 12, and are respectively arranged close to one of the support frames 11. Alternatively, in some embodiments, the two groups of sliding support devices 5 can also be arranged on the foundation. Each group of sliding support devices 5 can include a plurality of driving wheels and guide wheels arranged at intervals.

[0059] Furthermore, the stacker dismantling machine also includes a positioning guide device 6, which includes a positioning pin 61 and a correction wheel. The positioning pin 61 can be arranged on the base 12 or on the foundation. The positioning pin 61 is arranged corresponding to the support 71 of the mold platform 7 and is suitable for telescoping in the vertical direction to abut or separate from the bottom plate 711 of the support 71. The correction wheel can be arranged on the base 12, and the correction wheels are arranged in pairs, and multiple pairs can be arranged. Each pair of correction wheels is respectively located on both sides of the mold platform 7, and can be rollingly matched with the mold platform 7 to limit the position of both sides of the mold platform 7 to avoid position deviation of the mold platform 7 in the width direction.

[0060] In this embodiment, the stacking operation steps of the stacker are as follows:

[0061] S11: The mold platform 7 flows into the stacker and is supported on the sliding support device 5. The positioning pin 61 of the positioning guide device 6 abuts against the support 71 of the mold platform 7. The correcting wheel corrects the position of both sides of the mold platform 7 to ensure the accuracy of the position of the mold platform 7.

[0062] S12: The lifting device 3 is located at the bottom of the support frame 11, and the latch 321 is extended and inserted into the support 71 of the mold platform 7; the transmission chain 21 rotates upward, and the lifting device 3 drives the mold platform 7 to rise.

[0063] S13: The next die plate 7 flows into the destacker and the same action of S11 is performed. It can be understood that in this step, before the next die plate 7 flows in, the positioning pin 61 has been retracted so as not to interfere with the next die plate 7.

[0064] S14: the lifting device 3 drives the mold platform 7 to descend, and places the upper mold platform 7 on the lower mold platform 7, and the latch 321 retracts; the lifting device 3 continues to descend to the bottom of the support frame 11, and also executes the action of S12.

[0065] S15: Repeat steps S13 and S14 until the mold platform 7 is stacked to a preset number of layers. At this time, the state of the mold platform 7 is as follows: Figure 6As shown; the sliding support device 5 transfers the entire stack of mold platforms 7 out of the destacker, and the mold platforms 7 enter the next process.

[0066] In this embodiment, the destacking operation steps of the destacker are as follows:

[0067] S16: The whole stack of mold platforms 7 flows into the destacker and is supported on the sliding support device 5. The positioning pin 61 of the positioning guide device 6 abuts against the support 71 of the mold platform 7. The correcting wheels correct the positions of the two sides of the mold platform 7 to ensure the accuracy of the position of the mold platform 7.

[0068] S17: The lifting device 3 moves to the second layer at the bottom of the mold platform 7, and the latch 321 is inserted into the support 71 of the second layer of the mold platform 7 at the bottom; the transmission chain 21 rotates upward, and the lifting device 3 drives the second layer of the bottom and the mold platform 7 above it to rise.

[0069] S18: The sliding support device 5 transfers the mold platform 7 of the first layer at the bottom out of the destacker, and the mold platform 7 of the first layer enters the next process;

[0070] S19: the lifting device 3 descends to the bottom of the support frame 11, places the mold platform 7 on the sliding support device 5, and the latch 321 retracts; the lifting device 3 rises to the second layer position at the bottom of the mold platform 7 at this time, and also performs the action of S17.

[0071] S20: Repeat steps S18 and S19 until all the mold tables 7 flow out of the destacker.

[0072] Embodiment 2

[0073] like Figure 7-Figure 17 As shown, the difference between the destacker of the second embodiment and the destacker of the first embodiment is that the lifting device 3 includes a lifting seat 31, a clamping arm 33 arranged on the lifting seat 31, and a limiting structure arranged on the lifting seat 31 and cooperating with the clamping arm 33. The clamping arm 33 is swingably arranged on the lifting seat 31. When the lifting seat 31 moves upward, the clamping arm 33 swings to the extended position and abuts against the side of the mold platform 7, and the limiting structure is suitable for keeping the clamping arm 33 in the extended position. In this embodiment, the clamping arm 33 realizes the switching between the extended position and the retracted position by swinging around the lifting seat 31, without setting a driving structure, which is simple and economical.

[0074] Specifically, the limiting structure includes a clamping block 34 , which is disposed on the lifting seat 31 . In the lifting position, the clamping block 34 abuts against the bottom of the clamping arm 33 , so that the clamping arm 33 can be kept in the extended position, providing support force for the mold platform 7 .

[0075] like Figures 10 to 15As shown, the support frame 11 includes a first frame body 111 and a second frame body 112 , the transmission chains 21 of the two transmission devices 2 are arranged side by side between the first frame body 111 and the second frame body 112 , and the lifting seat 31 is connected to both transmission chains 21 .

[0076] like Fig.11 and 12 The lifting seat 31 includes an upper frame 313 and a lower frame 314 which are arranged at intervals. The upper frame 313 and the lower frame 314 are fixedly connected by two connecting shafts. The upper frame 313, the lower frame 314 and the two connecting shafts are collectively formed into a frame-like structure. The above-mentioned clamping arm 33 and the clamping block 34 are both arranged on the lower frame 314, and the two ends of the upper frame 313 are respectively connected to the two transmission chains 21.

[0077] One end of the clamping arm 33 is rotatably connected to the lower frame 314 , and the other end is located outside the transmission chain 21 . The clamping arm 33 swings by rotating around the lower frame 314 , thereby switching between the extended position and the retracted position.

[0078] The clamping block 34 is connected to one side of the lower frame 314 and is located below the clamping arm 33 . Preferably, the clamping block 34 is located below the rotation connection between the clamping arm 33 and the lower frame 314 .

[0079] So set up, such as Fig.14 As shown, when the lifting device 3 is in the extended position, the clamping arm 33 swings to a horizontal state, and the bottom of the clamping arm 33 abuts against the clamping block 34. At this time, the mold table 7 can flow into the stacker, and the support 71 of the mold table 7 corresponds to the position of the clamping arm 33 (as shown in FIG. Fig.16 When the transmission chain 21 rotates upward, the clamping arm 33 of the lifting device 3 is driven to rise. Under the action of the clamping block 34, the clamping arm 33 is kept in a horizontal position, and the upper surface of the clamping arm 33 can abut against the lower surface of the top plate 712 of the support 71 of the die table 7 (such as Fig.17 As shown in the figure, the die table 7 is driven to rise or fall. Furthermore, when the transmission chain 21 rotates downward, the lifting device 3 drives the clamping arm 33 to fall. When the clamping arm 33 contacts the upper surface of the bottom plate 711 of the support 71, the bottom plate 711 pushes the support arm to rotate upward, that is, the support arm clamping arm 33 rotates in the direction away from the clamping block 34, and finally the clamping arm 33 leaves the support 71 and switches to the retracted position.

[0080] It should be noted that if Fig.19 As shown, avoidance grooves are provided on the two side plates 713 of the support 71 of the mold platform 7, so that when the clamping arm 33 is in the extended position, the mold platform 7 can flow into the stacker without interfering with the clamping arm 33.

[0081] Furthermore, the stacker dismantling machine further comprises a guide structure, which is arranged between the lifting seat 31 and the support frame 11, and is suitable for guiding the lifting seat 31 to move in the vertical direction to ensure the stability of the lifting of the die table 7. Specifically, the guide structure comprises a guide groove 114 and a second pulley 312, the guide groove 114 is arranged on the support frame 11, the second pulley 312 is arranged on the lifting seat 31, and the second pulley 312 and the guide groove 114 are rollingly matched.

[0082] like Fig.13 and 14 As shown, the first frame 111 and the second frame 112 are both provided with the above-mentioned guide groove 114, and the guide groove 114 is roughly constructed as a "U"-shaped structure with an opening upward. Correspondingly, both ends of the lifting seat 31 are provided with a second pulley 312, and the second pulleys 312 at both ends of the lifting seat 31 are respectively rollingly matched with the guide grooves 114 on the first frame 111 and the second frame 112.

[0083] So set up, such as Fig.15 As shown, when the transmission chain 21 rotates downward, it can drive the clamping arm 33 to move to the outside of the support frame 11, and the clamping arm 33 is in the retracted position. In addition, when the transmission chain 21 rotates upward, the clamping arm 33 can rotate to a horizontal position under its own gravity, and abut against the clamping block 34 below to maintain the extended position.

[0084] In this embodiment, Fig.10 As shown, the lifting devices 3 can be arranged in multiple groups at intervals in the vertical direction, and are preferably arranged at even intervals. The interval height between two adjacent groups of lifting devices 3 is slightly greater than the height of the single-layer mold platform 7, such as Fig.17 As shown, when each group of lifting devices 3 supports a layer of mold platforms 7, adjacent mold platforms 7 are separated from each other. The number of lifting devices 3 can be adaptively adjusted according to the preset number of mold platforms 7 in the whole stack, and this application does not make specific restrictions on this.

[0085] In this embodiment, the stacking operation steps of the stacker are as follows:

[0086] S21: The mold platform 7 flows into the stacker and is supported on the sliding support device 5. The positioning pin 61 of the positioning guide device 6 abuts against the support 71 of the mold platform 7. The correcting wheel corrects the position of both sides of the mold platform 7 to ensure the accuracy of the position of the mold platform 7.

[0087] S22: The state of the lifting device 3 is as follows: Fig.14 As shown, the clamping arm 33 is in the retracted position; the transmission chain 21 rotates upward, driving the lifting device 3 to rotate upward, and the clamping arm 33 of the first lifting device 3 rotates to the extended position; the transmission chain 21 continues to rise until the clamping arm 33 abuts against the lower surface of the top plate 712 of the mold platform 7 support 71, and the clamping arm 33 drives the mold platform 7 to rise.

[0088] S23: The next die plate 7 flows into the destacker and performs the same action of S21.

[0089] S24: The transmission chain 21 continues to rotate upward, driving the lifting device 3 to rotate upward, and the clamping arm 33 of the lifting device 3 located downstream of the first lifting device 3 rotates to the extended position; the transmission chain 21 continues to rise until the clamping arm 33 abuts against the lower surface of the top plate 712 of the mold platform 7 support 71, and the clamping arm 33 drives the mold platform 7 to rise.

[0090] S25: Repeat steps S23 and S24 until the mold platform 7 is stacked to a preset number of layers. At this time, the state of the mold platform 7 is as follows: Fig.17 As shown; the transmission chain 21 rotates downward, and the die table 7 is placed on the sliding support device 5 in turn. The sliding support device 5 transfers the entire stack of die tables 7 out of the destacker, and the die table 7 enters the next process.

[0091] In this embodiment, the destacking operation steps of the destacker are as follows:

[0092] S26: The support arms of each lifting device 3 are switched to the extended state, and the lifting device 3 located at the bottom moves to the position of the second layer of mold platform 7 at the bottom of the entire stack of mold platforms 7.

[0093] S27: The whole stack of mold platforms 7 flows into the destacker and is supported on the sliding support device 5. The positioning pin 61 of the positioning guide device 6 abuts against the support 71 of the mold platform 7. The correction wheel corrects the position of both sides of the mold platform 7 to ensure the accuracy of the position of the mold platform 7. At this time, the state between the mold platform 7 and each lifting device 3 is as follows: Fig.16 As shown, the support arms of each lifting device 3 correspond to the support base 71 of one of the mold platforms 7, and there is no corresponding lifting device 3 at the position where the first layer of the mold platform 7 at the bottom is located.

[0094] S28: The transmission chain 21 rises and rotates, driving each lifting device 3 to rotate upward, and the support arms corresponding to each layer of the mold platform 7 abut against the lower surface of the top plate 712 of the corresponding mold platform 7 support 71, and each support arm drives the corresponding layer of the mold platform 7 to rise. When the support arms of each lifting device 3 lift the corresponding mold platform 7, the mold platform 7 and the lifting device 3 will present the following Fig.17 state, that is, the mold platforms 7 of each layer are separated from each other.

[0095] S29: The sliding support device 5 transfers the mold platform 7 of the first layer at the bottom out of the destacker, and the mold platform 7 of the first layer enters the next process;

[0096] S30: The transmission chain 21 rotates downward, driving the lifting device 3 to descend, and the support arm corresponding to the second-layer mold platform 7 at the bottom places the second-layer mold platform 7 on the sliding support device 5. The sliding support device 5 transfers the second-layer mold platform 7 at the bottom out of the stacker, and the second-layer mold platform 7 enters the next process. In this step, since the mold platforms 7 on each layer are separated from each other, there is no interaction force between the mold platforms 7 on each layer, and the mold platform 7 on the upper layer will not affect the outflow of the mold platform 7 on the lower layer.

[0097] S31: Repeat step S30 until all the mold tables 7 flow out of the destacker.

[0098] It can be seen that in the destacker of the second embodiment, when stacking, the transmission chain 21 first drives the lifting device 3 to rise, each lifting device 3 lifts the corresponding mold platform 7 one by one, and the transmission chain 21 then drives the lifting device 3 to descend, and the mold platforms 7 stacked to a predetermined number of layers are placed one by one on the sliding support device 5, so that the stacking of the mold platforms 7 can be achieved. When destacking, the transmission chain 21 first drives the lifting device 3 to rise, each lifting device 3 lifts the mold platforms 7 of the corresponding layer one by one, and the transmission chain 21 then drives the lifting device 3 to descend, and the mold platforms 7 of each layer are placed one by one on the sliding support device 5 and flow away, so that the destacking of the mold platforms 7 can be achieved. In the destacker of this embodiment, whether it is a stacking operation or a destacking operation, the lifting device 3 does not need to repeatedly perform the rising or falling action, which reduces the lifting stroke and further improves the stacking efficiency.

[0099] In addition, the present invention also provides a precast concrete component production line, including the destacker as described in any of the above embodiments. Because the precast concrete component production line of the present invention includes the destacker, it has the same technical effect as the destacker, and will not be described in detail here.

[0100] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
