Description

Technical Field

[0001] The utility model relates to a concrete block production device, in particular to a block rotating fixture. Background Art

[0002] In recent years, aerated concrete blocks have gradually replaced traditional red bricks or blue bricks and become the preferred material in many civil engineering projects. Because of this, how to improve their production efficiency and output has become a problem often considered by production enterprises. In the production process of aerated concrete blocks, there is a process of misaligned stacking of aerated concrete blocks. At present, the method adopted by manufacturers is to stack them misaligned manually. Obviously, this method requires a large amount of manpower and has very low efficiency. To solve this problem, the applicant (Ruian Ruigang Machinery Co., Ltd.) has made corresponding designs and applied for a utility model patent named "A Full-automatic Rotating Fixture" (Publication No. CN204054046U). The rotating fixture includes a rotating mechanism, a clamping mechanism, and left and right clamping plates. The rotating mechanism includes a rotating bracket and a hydraulic slewing device. During operation, the rotating fixture clamps the block through rubber pads on the lowermost ends of the left and right clamping plates. However, there is friction between the rubber pads and the blocks. Over time, the rubber pads become thinner, so that the clamping force of the left and right clamping plates will gradually become smaller, and the rubber pads need to be replaced, which is very troublesome. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the utility model innovatively provides a block rotating fixture capable of adjusting the position of rubber pads.

[0014] As Figure 1 shown in Figure 2 and

[0015] shown in Figure 2 , this block rotating clamp includes a frame 1, a walking trolley 2, a rotary drive 7, a left and a right clamping hand 5, and a clamping power source 10. The clamping power source 10 can drive the left and right clamping hands 5 to perform a clamping action. The rotary drive 7 can drive the left and right clamping hands 5 to rotate on a horizontal plane, and the walking trolley 2 can drive the left and right clamping hands 5 to move on the frame 1. Figure 3 As shown in, a rubber pad 51 is installed on the inner side of the lower end of each clamping hand 5.As shown in the figure, a bottom plate 50 is provided at the lower end of the clamping hand 5. A rubber pad 51 is located inside the bottom plate 50. An adjusting plate 52 is provided between the bottom plate 50 and the rubber pad 51. The rubber pad 51 has a countersunk hole 510. A positioning bolt 54 is provided in the countersunk hole 510. The positioning bolt 54 passes through the adjusting plate 52 and is threadedly connected to the first screw hole 501 of the bottom plate 50. A second screw hole 502 is provided on the bottom plate 50. An adjusting bolt 53 is threadedly connected in the second screw hole 502. The adjusting bolt 53 acts on the adjusting plate 52. When the rubber pad 51 gradually becomes thinner due to friction, by rotating the positioning bolt 54 outwards, the rubber pad 51 is made to come out a little ( Figure 3 in the left direction in the figure), and then the adjusting bolt 53 is rotated so that the adjusting bolt 53 abuts against the adjusting plate 52. The adjusting plate 52 then acts on the rubber pad 51 (applying a leftward force to the rubber pad 51), and thus the rubber pad 51 is fixed. With this structure, even when the rubber pad 51 becomes thinner, the working surface of the rubber pad 51 can be adjusted to the reference position, so it is not necessary to frequently replace the rubber pad.

[0016] In order to enable the walking trolley 2 to move on the frame 1, as Figure 1 shown, a horizontal guide rail 11 is provided on the frame 1. Walking wheels are provided at both ends of the walking trolley 2. The walking wheels are slidably arranged on the horizontal guide rail 11. As Figure 4 shown, a walking motor 13 is installed on the walking trolley 2. The walking motor 13 is in transmission connection with a transmission rotating rod 14. A rotatable transmission shaft 15 is installed on the walking trolley 2. One end of the transmission shaft 15 is connected to the transmission rotating rod 14. A first gear 16 is connected to one end of the transmission shaft 15. A horizontal rack 17 parallel to the horizontal guide rail 11 is provided on the frame 1. The horizontal rack 17 meshes with the first gear 16. With this structure, the walking motor 13 drives the transmission rotating rods 14 on both sides to rotate, which drives the first gears 16 on both sides to rotate on the horizontal rack 17. In this way, the walking trolley 2 can move on the horizontal guide rail 11 of the frame 1. At the same time, since the first gears 16 on both sides rotate synchronously, the two ends of the walking trolley 2 also move synchronously, so the walking is more stable.

[0017] As Figure 2 shown, the left and right clamping hands 5 are both slidably arranged in the guide frame 9 through rollers (the rollers are not shown). The clamping power source 10 can drive the left and right clamping hands 5 to move relatively. The guide frame 9 is connected to the mounting plate 8, and the mounting plate 8 is connected to the rotary drive 7. The rotary drive 7 is installed on the lifting bracket 3. A hydraulic lifting cylinder 6 is installed on the walking trolley 2. The hydraulic lifting cylinder 6 is in transmission connection with the lifting bracket 3. Through the drive of the hydraulic lifting cylinder 6, the left and right clamping hands 5 can be lifted up and down.

[0018] As Figure 4As shown in the figure, in order to make the lifting bracket 3 lift stably, a vertical support 4 is installed on the walking trolley 2, and two front and rear guide wheel sets are installed on the vertical support 4. Each guide wheel set includes two left and right guide wheels 40. Vertical guide bars 30 are provided on the front and rear surfaces of the lifting bracket 3, and the vertical guide bars 30 are located between the left and right guide wheels 40. By guiding the vertical guide bars 30 with the two guide wheels 40, the lifting bracket 3 can be lifted more smoothly.

[0019] As Figure 4 shown in the figure, in order to make the left and right sides of the lifting bracket 3 lift synchronously and prevent the lifting bracket 3 from jamming during lifting, a rotatable balance rod 41 is installed on the vertical support 4, and two second gears 42 are connected to the balance rod 41. Vertical racks 31 are provided on both sides of the lifting bracket 3, and the second gears 42 on the same side are engaged with the vertical racks 31. Since the two second gears 42 on both sides rotate synchronously, the left and right sides of the lifting bracket 3 also move synchronously, so the lifting is more stable.
