Description

Technical Field

[0001] The utility model relates to a production device for concrete slabs, in particular to a machine for separating concrete slabs. Background Art

[0002] With the progress of technology and the enhancement of environmental awareness, in recent years, aerated concrete blocks / slabs (hereinafter referred to as blocks / slabs) have gradually replaced traditional red bricks or blue bricks and become the preferred materials in many large-scale civil engineering projects. The challenge faced by current production enterprises is how to improve the production efficiency and output of blocks / slabs. In the production process of aerated concrete blocks / slabs, the concrete is mixed well and then poured into a walking formwork, where it is formed. Then, it is transported to the next station for cutting through the walking formwork. After being cut into multiple upper and lower layers of slabs, it is finally sent into an autoclave for autoclave curing. Since the cut blocks will still adhere to each other after the concrete solidifies, separation is required after curing. Currently, all slab separators are of mobile structure. For example, the utility model patent named "Multifunctional Aerated Concrete Block Separator" (Publication No. CN104385453A) allows the lifting frame to reach the bottom of the block by the movement of the walking frame, and then the lifting frame is lifted. However, since the walking frame is mobile, even with the most powerful braking, there will inevitably be slight movement or shaking when separating the blocks or slabs, thus affecting the yield rate. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the utility model innovatively provides a fixed concrete slab separator with more stable operation.

[0004] This fixed concrete slab separator includes a fixed frame, a lifting seat, a lifting mechanism, and a clamping device.

[0020] As Figure 1 shown, this fixed - type concrete slab separator includes a fixed frame 1, a lifting seat 2, a lifting mechanism 8 and a clamping device 9. The lifting seat 2 is slidably arranged on the fixed frame 1 in a liftable manner, and the lifting mechanism 8 is in transmission connection with the lifting seat 2. By the pulling of the lifting mechanism 8, the lifting seat 2 can move up and down on the fixed frame 1, thereby slowly lifting the building block.

[0021] As Figure 1 shown, two parallel fixed beams 4 are installed on the fixed frame 1, and the clamping devices 9 are installed on both fixed beams 4. As Figure 3 shown, and two parallel lifting beams 5 are arranged left and right above the fixed beam 4, and the clamping devices 9 are installed on each lifting beam 5. A separation hydraulic cylinder 7 is installed on the lifting beam 5, and the piston rod of the separation hydraulic cylinder 7 is connected to the fixed beam 4; As Figure 1 shown, several transmission wheel mechanisms 3 are arranged below the fixed frame 1, and several transmission wheel mechanisms 3 are arranged in a row and pass through between the left and right fixed legs of the fixed frame 1. As Figure 2 shown, the transmission wheel mechanism 3 includes a transmission wheel support 30, a transmission wheel 31 and a transmission wheel power source 32. The transmission wheel 31 is rotatably installed on the transmission wheel support 30, the transmission wheel power source 32 is in transmission connection with the transmission wheel 31, and the lifting seat 2 can be lowered to a position lower than the transmission wheel 31.

[0022] Its working principle is as follows. The driving wheel power source 32 drives the driving wheel 31 to rotate, so that the plate placed on a row of driving wheels 31 can be pushed forward. Since the lifting seat 2 can be lowered to a position lower than the driving wheel 31, and the lifting seat 2 can enter between the front and rear two driving wheel mechanisms 3, the plate can pass through between the left and right fixing legs of the fixing frame 1 and pass above the lifting seat 2. In this way, the lifting mechanism 8 can directly drive the lifting seat 2 to rise and lift the block plate. After the block plate is lifted, the left and right rows of clamping devices 9 on the fixing beam 4 clamp a layer of block plates, and the left and right rows of clamping devices 9 on the lifting beam 5 clamp the upper layer of block plates. When the separation hydraulic cylinder 7 is driven, it drives the lifting beam 5 to move upward, so that the clamping device 9 on the lifting beam 5 clamps the plate and separates it from the lower layer of plates; by driving the lifting seat 2 to gradually rise through the lifting mechanism 8 and then through the clamping and separation of the upper and lower layer clamping devices 9, the block plates are separated layer by layer.

[0023] As Figure 3 shown, the lifting mechanism 8 includes a hydraulic cylinder 81, a first gear 85, a second gear 87, a steering gear 86, a first chain 830 and a second chain 840; two parallel upper cross beams 6 are installed on the fixing frame 1, and a connecting support 80 is installed on each upper cross beam 6. The connecting support 80 is hinged to the hydraulic cylinder 81, the piston rod of the hydraulic cylinder 81 is hinged to the horizontal slider 82, a guide groove 820 is installed on the upper cross beam 6, and the horizontal slider 82 is slidably arranged in the guide groove 820 through a pulley. A first chain connecting head 83 and a second chain connecting head 84 are installed on the horizontal slider 82. The first chain connecting head 83 is connected to one end of the first chain 830. The first gear 85 is rotatably installed at one end of the upper cross beam 6. As Figure 4 shown, the first chain 830 bypasses the first gear 85 and is connected to a lower lifting seat 2; the second chain connecting head 84 is connected to one end of the second chain 840. The second gear 87 is rotatably installed at one end of the upper cross beam 6, the steering gear 86 is rotatably installed on the upper cross beam 6 and is located between the first gear 85 and the second gear 87. The second chain 840 first bypasses the steering gear 86 and then bypasses the second gear 87 and is connected to the other lower lifting seat 2. Through the drive of the hydraulic cylinder 81, the first chain 830 and the second chain 840 can synchronously lift the left and right lifting seats 2.

[0024] In order to keep the four chains moving synchronously, as Figure 3 shown, the two first gears 85 on the same side of the two upper cross beams 6 are connected by a first coupling shaft 88, and the two second gears 87 on the same side of the two upper cross beams 6 are connected by a second coupling shaft 89. With this structure, the two first chains 830 and the two second chains 840 can synchronously lift the left and right lifting seats 2 in the form of four lifting points, so that the lifting of the lifting seat 2 is more stable.

[0025] In order to enable the lifting seat 2 to lift smoothly on the fixing frame 1, as Figure 1 shown, a vertical guiding frame 10 is installed on the fixing frame 1. Sliding parts 20 are provided on both sides of the lifting seat 2. Rollers are installed on the sliding parts 20, and the rollers are slidably arranged in the guiding frame 10. Two first chains 830 are correspondingly connected to the sliding parts 20 on both sides of one lifting seat 2, and two second chains 840 are correspondingly connected to the sliding parts 20 on both sides of the other lifting seat 2. Through this structure, the lifting seat 2 can lift and lower on the fixing frame 1 very smoothly and smoothly.

[0026] As Figure 6 shown in Figure 7 , the clamping device includes an oil cylinder 91, a rubber block 93 and a rubber seat 92. The rubber block 93 is installed on the rubber seat 92, and the telescopic rod 910 of the oil cylinder 91 is hinged to the rubber seat 92. During operation, the oil cylinder 91 drives the rubber seat 92 to move forward, and the rubber block 93 acts on the building block. Of course, building block clamps are provided on both the left and right sides of the building block, and the building block clamps on both sides act on the building block at the same time. When the lifting frame carries the building block clamps, the building block is lifted, so as to be separated from the building block below.

[0027] In order to facilitate the disassembly and assembly of the rubber block 93 and the rubber seat 92, as Figure 7 shown, the utility model has a connecting part 930 on the inner side of the rubber block 93. Card slots are provided on both the upper and lower surfaces of the connecting part 930, and the rubber seat 92 has a connecting groove. Protruding parts 920 are provided on both the upper and lower inner side surfaces of the connecting groove. The connecting part 930 of the rubber block 93 is arranged in the connecting groove of the rubber seat 92, and at the same time, the protruding parts 920 of the rubber seat 92 are fitted in the card slots of the rubber block 93. Through this structure, when connecting the rubber block 93 and the rubber seat 92, as long as the connecting part 930 of the rubber block 93 is inserted into the connecting groove from the side of the rubber seat 92, the connecting part 930 of the rubber block 93 is connected in the connecting groove of the rubber seat 92, and at the same time, the protruding parts 920 of the rubber seat 92 are stuck in the card slots of the rubber block 93. Due to the limitation of the protruding parts 920, the rubber block 93 is not easy to fall out. When replacement and disassembly are required, as long as the rubber block 93 is pulled out from the side, it is very convenient. Since only the rubber block 93 needs to be replaced, the maintenance cost can be significantly reduced.

[0028] In addition, the rear part of the rubber seat 92 has a hinge support 921 and two guide supports 922. The hinge support 921 is located between the two guide supports 922. The telescopic rod 910 of the oil cylinder 91 is hinged to the hinge support 921, and the two guide supports 922 are both connected to the guide shaft 94. When the telescopic rod 910 of the oil cylinder 91 pushes the rubber seat 92 to move back and forth, the guide shaft 94 moves back and forth in the guide sleeve (the guide sleeve is not shown), which plays a guiding role in the back-and-forth movement of the rubber seat 92, so that the rubber seat 92 will not swing, and thus the front surface of the rubber block 93 acts on the building block.

[0029] The guide support 922 is a bushing or a plate surface. When the guide support 922 is a bushing, the guide shaft 94 can be connected to the bushing with an interference fit; when the guide support 922 is a plate surface, the guide shaft 94 can be connected to the plate surface by bolts. The guide supports 922 on both the left and right sides can both be bushings, or one side can be a bushing and the other half can be a plate surface. For old models, adopting the latter only requires replacing fewer parts, which can save more costs.

[0030] Finally, it is worth mentioning that the cross-sections of the convex part 920 and the card slot are both semi-circular. In this way, the convex part 920 can easily enter the card slot.
