Description

[Technical field]

[0001] The utility model relates to the field of block machines, in particular to a gas-liquid braking device of a block machine. [Background technology]

[0002] Masonry blocks are man-made blocks made of concrete and other materials. They are larger in size than bricks. Bricks cut from them are a new type of wall material. They have the advantage of fast laying speed and meet the requirements of walls in the development of building industrialization.

[0003] When the heightened block machine produces heightened bricks, the friction between the base material in the pressing mold and the mold increases because the bricks are high. Therefore, during the demoulding process, the pressing head 104' needs to be kept stationary to successfully demould. Otherwise, during the demoulding process, the pressing head 104' will be moved by the demoulding effect, affecting the quality of the blocks and even scrapping the blocks. Therefore, it is particularly important to use a braking mechanism to maintain the braking effect of the pressing head 104'.

[0004] As attached Figure 1 and 2 As shown, the braking mechanism 100' of the old-fashioned block machine mostly adopts a hydraulic braking solution, using a hydraulic control valve 101' and an accumulator 102' to push the brake cylinder 103' to achieve braking. There are three disadvantages:

[0005] 1. The brake oil cylinder 103' is expensive, and as the hydraulic oil temperature increases, the oil cylinder seal fails, thereby causing brake failure.

[0006] 2. The main engine hydraulic station is required, so other hydraulic actions cannot be performed during braking, affecting efficiency.

[0007] 3. Once the brake cylinder 103' needs to be repaired, the spare parts supply cycle is long due to the small number of matching parts.

[0008] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Contents of the utility model]

[0009] The utility model provides a gas-liquid brake device for a block machine. The gas-liquid brake device adopts a mature and reliable gas-over-oil brake technology and has high braking efficiency.

[0010] The utility model is implemented as follows: a gas-liquid brake device for a block machine comprises an air brake valve, a booster pump, a brake mechanism and a synchronous shaft; the air brake valve and the booster pump are installed on a frame of the block machine, two mounting seats are fixedly installed on the frame, and the two ends of the synchronous shaft are rotatably connected to the two mounting seats respectively; the output end of the air brake valve is connected to the input end of the booster pump through a pipeline, and the output end of the booster pump is connected to the brake mechanism through a pipeline; the brake mechanism is fixedly connected to the outside of the synchronous shaft.

[0011] Furthermore, the output end of the booster pump is connected to two braking mechanisms via a three-way pipe.

[0012] Furthermore, the braking mechanism includes a brake caliper and a brake disc; the interior of the brake caliper is provided with a plurality of pistons and a chamber for the movement of the pistons, and the brake caliper also includes two brake pads, which are respectively installed on both sides of the brake disc. During braking, gas enters the chamber to compress the piston to move and drive the brake pad to approach the brake disc to brake.

[0013] Furthermore, a friction plate is provided between the brake pad and the brake disc.

[0014] Furthermore, a through hole is formed in the middle of the brake disc for the synchronization shaft to pass through.

[0015] Furthermore, the block machine also includes a driving mechanism for rotating a pressure head and a synchronous shaft.

[0016] Furthermore, two gears are fixedly provided outside the synchronization shaft; and a gear row meshing with the gears is provided on the pressure head.

[0017] Furthermore, a support plate is provided on the frame, a support seat is fixedly installed on the support plate, and a guide ring is fixedly installed in the support seat; a guide column is installed on the top of the pressure head, and the guide column is inserted into the guide ring.

[0018] Furthermore, the brake mechanism also includes a fixing block, one end of which is fixedly connected to the brake caliper via bolts, and the other end of which is welded to the support plate.

[0019] Furthermore, there are two fixed blocks, which are distributed on both sides of the synchronization shaft.

[0020] The advantages of the utility model are:

[0021] 1. The gas-liquid brake device of the block machine of the utility model compresses the gas to drive the brake mechanism to work through the synergistic effect of the gas brake valve and the booster pump. The brake mechanism adopts a mature engineering machinery disc brake caliper. The batch mature brake caliper has low cost, sufficient supply of accessories and short supply cycle.

[0022] 2. The air brake valve and booster pump adopt an independent air-over-oil braking solution, which does not require the use of the main engine hydraulic system, so compound actions can be achieved to improve braking efficiency; the air-over-oil braking technology is mature and reliable, and the brake fluid is resistant to high temperatures, and the temperature above 100° has little effect on braking.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0034] See also Figures 3 to 6As shown, the utility model provides a gas-liquid brake device 100 for a block machine, comprising an air brake valve 1, a booster pump 2, a brake mechanism 3, and a synchronous shaft 4; the air brake valve 1 and the booster pump 2 are installed on a frame 5 of the block machine, and two mounting seats 6 are fixedly installed on the left and right of the frame 5, and the two ends of the synchronous shaft 4 are rotatably connected to the two mounting seats 6 respectively; the output end of the air brake valve 1 is connected to the input end of the booster pump 2 through a pipeline 7, and the output end of the booster pump 2 is connected to the brake mechanism 3 through a pipeline 7; the brake mechanism 3 is fixedly connected to the outside of the synchronous shaft 4.

[0035] The gas-liquid brake device 100 of the block machine of the utility model compresses the gas to drive the brake mechanism 3 to work through the synergistic effect of the gas brake valve 1 and the booster pump 2. The brake mechanism 3 adopts a mature engineering machinery disc brake caliper 31, which has at least the following beneficial technical effects:

[0036] 1. Use the mature batch brake caliper 31, which has low cost, sufficient supply of accessories and short supply cycle.

[0037] 2. The air brake valve 1 and the booster pump 2 adopt an independent air-over-oil braking solution. The air-over-oil braking solution uses compressed air to push the brake mechanism 3 to achieve the purpose of braking. The host hydraulic system does not need to be used, so compound actions can be achieved to improve braking efficiency; the air-over-oil braking technology is mature and reliable, and the brake fluid is resistant to high temperatures, and the temperature above 100° has little effect on braking.

[0038] In the present invention, the output end of the booster pump 2 is connected to two brake mechanisms 3 via a three-way pipe 7. By providing two brake mechanisms 3, braking stability can be ensured.

[0039] In the utility model, the brake mechanism 3 includes a brake caliper 31 and a brake disc 32; the brake caliper 31 is provided with a plurality of pistons 33 and a chamber 34 for the piston 33 to move inside, and the brake caliper 31 also includes two brake pads 35, which are respectively installed on both sides of the brake disc 32. When braking, gas enters the chamber 34 to compress the piston 33 to move and drive the brake pads 35 to approach to brake the brake disc 32. When the brake mechanism 3 brakes, gas is pressed into the chamber 34, and the piston 33 presses the two brake pads 35 against the brake disc 32 under the action of air pressure to generate friction and brake; when not braking, the air pressure decreases, and the piston 33 and the brake pad 35 return to their positions.

[0040] Preferably, the brake disc 32 is made of alloy material. The brake disc 32 is a circular brake disc.

[0041] Preferably, the number of the pistons 33 is 4, and they are distributed in pairs on both sides of the brake disc 32. One piston 33 is correspondingly installed in one chamber 34, and two pistons 33 on the same side push one brake pad 35 to move.

[0042] In the utility model, a friction plate 36 is further provided between the brake pad 35 and the brake disc 32. To ensure that the brake is released, when not braking, the gap between the friction plate 36 and the brake disc 32 is 0.2 mm on each side. The brake disc 32 will expand due to heat, and its thickness will also change slightly. The 0.2 mm gap can avoid dragging.

[0043] In the present invention, a through hole is formed in the middle of the brake disc 32 for the synchronous shaft 4 to pass through. The brake disc 32 is fixedly connected to the synchronous shaft 4 through the through hole and rotates with the synchronous shaft 4.

[0044] In the utility model, the block machine also includes a pressure head 8 and a driving mechanism, which drives the synchronous shaft 4 to rotate and drives the pressure head 8 to move up and down. Two gears 10 are fixedly provided on the outside of the synchronous shaft 4; the pressure head 8 is provided with a tooth row 9 meshing with the gear 10. The rotation of the synchronous shaft 4 drives the gear 10 to move up and down on the tooth row 9, thereby driving the pressure head 8 to move up and down.

[0045] In the present invention, a support plate 51 is provided on the frame 5, a support seat 52 is fixedly mounted on the support plate 51, a guide ring 53 is fixedly mounted in the support seat 52; a guide column 54 is installed at the top of the pressure head 8, and the guide column 54 is inserted into the guide ring 53. When the pressure head 8 moves, the guide column 54 moves up and down along the guide ring 53, ensuring the stability of the pressure head 8 to be able to move vertically up and down.

[0046] In the present invention, the brake mechanism 3 further comprises a fixing block 37, one end of which is fixedly connected to the brake caliper 31 by a bolt 33, and the other end is welded to the support plate 51. The brake caliper 31 is fixed by the fixing block 37, so that the two brake mechanisms 3 are stably arranged.

[0047] In the present invention, there are two fixing blocks 37 , which are distributed on both sides of the synchronization shaft 4 .

[0048] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
