Description

Technical Field

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

[0002] With the advancement of technology and the enhancement of environmental awareness, in recent years, aerated concrete blocks / sheets (referred to as blocks / sheets) have gradually replaced traditional red bricks or blue bricks and become the preferred material in many large-scale civil engineering projects. The challenge currently faced by manufacturers is how to improve the production efficiency and output of blocks / sheets. In the production process of aerated concrete blocks / sheets, after the concrete is mixed, it is poured into the walking mold frame and formed in the walking mold frame. Then it is transported to the next station through the walking mold frame for cutting. After being cut into upper and lower multi-layer sheets, it is finally sent to the autoclave for autoclave curing. Since the cut blocks will still be partially bonded after the concrete solidifies, they must be separated after curing. At present, plate separators are all mobile structures. For example, the utility model patent named "Aerated Concrete Multifunctional Block Separator" (Announcement No. CN104385453A) uses the walking frame to allow the lifting frame to reach the bottom of the block, and then lift the lifting frame. The lifting frame is pulled by a chain, but the chain will shake, and will be stretched after long-term use, thereby affecting the lifting accuracy of the lifting frame and affecting the subsequent clamping and separation work. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model innovatively provides a mobile block separator with higher lifting accuracy.

[0004] This mobile block separator includes a fixed frame, a traveling trolley, two lifting seats, a lifting mechanism and a clamping device. The traveling trolley is slidably arranged on the fixed frame, and two left and right longitudinal beams are installed on the traveling trolley. The lifting seat can be lifted and slid and is arranged on the longitudinal beams, and the lifting mechanism is connected to the lifting seat by transmission. Two parallel fixed beams are installed on the traveling trolley, and the clamping device is installed on the two fixed beams. Two left and right parallel lifting beams are arranged above the fixed beams, and the clamping device is installed on each lifting beam.

It is characterized in that: the lifting mechanism is a lifting hydraulic cylinder, the upper end of the longitudinal beam is connected to a support, the lifting hydraulic cylinder is hinged on the support, the lifting seat includes a lifting leg and a lifting foot, and the piston rod of the lifting hydraulic cylinder is hinged to the lifting leg of the lifting seat.

[0005] The lifting leg of the lifting seat is hollow, and the piston rod of the lifting hydraulic cylinder enters into the hollow interior of the lifting leg and is hinged with the lifting leg.

[0006] The fixing frame is provided with a horizontal guide rail. The two ends of the traveling trolley are provided with traveling wheels, and the traveling wheels are slidably arranged on the horizontal guide rail.

[0021] As Figure 1 shown, this mobile block separator includes a fixed frame 1, a traveling trolley 3, two lifting seats 2, a lifting mechanism, and a clamping device 9. The traveling trolley 3 is slidably arranged on the fixed frame 1. As Figure 2 shown, two longitudinal beams 6 are installed on the traveling trolley 3. The lifting seats 2 are slidably arranged on the longitudinal beams 6 in a liftable manner. The lifting mechanism is in driving connection with the lifting seats 2. Through the lifting mechanism, the lifting seats 2 can be driven to move up and down on the longitudinal beams 6, and the traveling trolley 3 can drive the lifting seats 2 to move horizontally.

[0022] As Figure 2 shown, two parallel fixed beams 4 are installed on the traveling trolley 3. Clamping devices 9 are installed on both of the two fixed beams 4. As Figure 5 shown, two parallel lifting beams 5 are arranged above the fixed beams 4. Clamping devices 9 are installed on each of the two lifting beams 5. A separating hydraulic cylinder 7 is installed on the lifting beam 5. The piston rod of the separating hydraulic cylinder 7 is connected to the fixed beam 4. As Figure 4 shown, the lifting mechanism is a lifting hydraulic cylinder 8 (an oil cylinder). A support 60 is connected to the upper end of the longitudinal beam 6. The lifting hydraulic cylinder 8 is hinged to the support 60. The lifting seat 2 includes a lifting leg 20 and a lifting foot 21. The piston rod of the lifting hydraulic cylinder 8 is hinged to the lifting leg 20 of the lifting seat 2.

[0023] Its working principle is as follows: The blocks are conveyed to the lower part of the fixed frame 1. The traveling trolley 3 moves forward, driving the lifting seats 2 to the lower parts of both ends of the blocks. In this way, the lifting hydraulic cylinder 8 directly drives the lifting seats 2 to rise, lifting the blocks. After the blocks are lifted, the left and right rows of clamping devices 9 on the fixed beam 4 clamp one layer of blocks, and the left and right rows of clamping devices 9 on the lifting beam 5 clamp the upper layer of blocks. When the separating hydraulic cylinder 7 is driven, it drives the lifting beam 5 to move upward. In this way, the clamping devices 9 on the lifting beam 5 clamp the blocks and separate them from the lower-layer blocks; by driving the lifting seats 2 to gradually rise through the lifting hydraulic cylinder 8 and then through the clamping and separation of the upper and lower-layer clamping devices 9, the blocks are separated layer by layer. Since the lifting hydraulic cylinder 8 is not fully utilized and will not deform, the structure is more stable, and the movement accuracy of the lifting seats 2 is not affected during long-term operation.

[0024] like Figure 4 As shown, the lifting leg 20 of the lifting seat 2 is hollow, and the piston rod of the lifting hydraulic cylinder 8 enters the hollow interior of the lifting leg 20 and is hinged to the lifting leg 20. Since the piston rod of the lifting hydraulic cylinder 8 is hinged to the interior of the lifting leg 20, the structure is more stable, the concentricity is higher, and the lifting is more stable.

[0025] like Figure 1 and Figure 3 As shown, in order to make the walking trolley 3 walk on the fixed frame 1, a horizontal guide rail 11 is provided on the fixed frame 1, and walking wheels are provided at both ends of the walking trolley 3, and the walking wheels are slidably arranged on the horizontal guide rail 11. A walking motor 10 is installed on the walking trolley 3, and the walking motor 10 is connected to the transmission rotating rod 12 in transmission, and a rotatable transmission shaft 13 is installed on the walking trolley 3, one end of the transmission shaft 13 is connected to the transmission rotating rod 12, and one end of the transmission shaft 13 is connected to the first gear 14, and a horizontal rack 15 parallel to the horizontal guide rail 11 is provided on the fixed frame 1, and the horizontal rack 15 is meshed with the first gear 14. Through this structure, the walking motor 10 drives the transmission rotating rods 12 on both sides to rotate, and drives the first gears 14 on both sides to rotate on the horizontal rack 15, so that the walking trolley 3 can move on the horizontal guide rail 11 of the frame 1, and at the same time, because the first gears 14 on both sides rotate synchronously, the two ends of the walking trolley 3 also move synchronously, so the walking is more stable.

[0026] like Figure 4 As shown, the two lifting seats 2 are connected by a connecting beam 23, a rotatable balance bar 24 is mounted on the connecting beam 23, two second gears 25 are connected to the balance bar 24, and vertical racks 61 are provided on the two longitudinal beams 6. The second gears 25 on the same side are meshed with the vertical racks 61. Since the second gears 25 on both sides rotate synchronously, the left and right sides of the lifting seat 2 also move synchronously, so the lifting is more stable.

[0027] like Figure 4 As shown, the lifting seat 2 is provided with a vertical support 26, and two front and rear I-shaped wheels 27 are provided on the vertical support 26. Vertical guide bars 62 are provided on the front and rear surfaces of the longitudinal beam 6, and the vertical guide bars 62 are located between the left and right I-shaped wheels 27. Through the guidance of the two I-shaped wheels 27 to the vertical guide bars 62, the lifting seat 2 can be lifted and lowered more smoothly.

[0028] like Figure 6 and Figure 7As shown in the figure, 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, there are building block clamps on both the left and right sides of the building block. 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 and separated from the building block below.

[0029] 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 portion 930 on the inner side of the rubber block 93. There are card slots on both the upper and lower surfaces of the connecting portion 930, and the rubber seat 92 has a connecting groove. There are protruding portions 920 on both the upper and lower inner side surfaces of the connecting groove. The connecting portion 930 of the rubber block 93 is arranged in the connecting groove of the rubber seat 92. At the same time, the protruding portion 920 of the rubber seat 92 is fitted in the card slot of the rubber block 93. With this structure, when connecting the rubber block 93 and the rubber seat 92, as long as the connecting portion 930 of the rubber block 93 is inserted into the connecting groove from the side of the rubber seat 92, the connecting portion 930 of the rubber block 93 is connected in the connecting groove of the rubber seat 92. At the same time, the protruding portion 920 of the rubber seat 92 is stuck in the card slot of the rubber block 93. Due to the limitation of the protruding portion 920, the rubber block 93 is not easily dropped out. When it needs to be replaced and disassembled, as long as the rubber block 93 is pulled out from the side, which is very convenient. Since only the rubber block 93 needs to be replaced, the maintenance cost can be significantly reduced.

[0030] 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 both guide supports 922 are 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 does not swing, and thus the rubber block 93 acts on the building block frontally.

[0031] 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 in interference fit with the bushing; 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 and can save more costs.

[0032] Finally, it is worth mentioning that the cross-sections of the convex portion 920 and the card slot are both semicircular. In this way, the convex portion 920 can easily enter the card slot.
