Description

Technical Field

[0001] The present invention relates to the technical field of breaking machines, in particular to a low-damage concrete blank breaking machine. Background Art

[0002] When producing autoclaved aerated concrete blocks, the concrete blanks need to be separated before they are steam-cured. When breaking apart, the adjacent concrete blanks need to be clamped first, and then one of the blanks needs to be moved to achieve the breaking operation. When breaking apart, if the clamping force on the concrete blanks is too small, the movement of one concrete blank will cause the movement of another concrete blank, and the breaking cannot be completed; if the clamping force is too large, the concrete blank will be damaged. In the existing breaking machine technology, due to the relatively simple clamping structure, the clamping force on the concrete blank is always maintained at a constant value. Therefore, in order to ensure that it can be broken apart, the clamping force will be set too large, which can easily cause damage to the blank. Summary of the Invention

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; they may refer to mechanical or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0051] The present invention relates to a low-damage concrete blank breaking machine, such as Figures 1 to 6 As shown, its main structure includes an intermediate frame 1, a gantry frame 2, a slide bar 3, a bottom splitter 4 and a top splitter 5. The specific structure of each component is as follows:

[0052] The middle frame 1 is fixed on the ground;

[0053] The gantry frame 2 is fixedly arranged on the ground, and the beam above the gantry frame 2 spans over both sides of the intermediate frame 1.

[0054] A plurality of slide bars 3 are arranged in a horizontal array on the intermediate frame 1; all the slide bars 3 slide horizontally on the intermediate frame 1 without being driven by a power source and are in a freely sliding form;

[0055] Multiple bottom dividers 4 are divided into multiple groups (generally two groups) as needed and are arranged on both sides of the intermediate frame 1. The bottom dividers 4 in each group are arranged in a horizontal array on the intermediate frame 1, and the array direction is perpendicular to the array direction of the slide rod 3. The bottom dividers 4 are driven by a power mechanism to slide horizontally on the intermediate frame 1 at a height lower than the slide rod 3, and the sliding path is parallel to the sliding path of the slide rod 3. Each bottom divider 4 includes a fixed connector 41 and a sliding connector 42. The fixed connector 41 is relatively fixed to the bottom divider 4, and the sliding connector 42 is driven by an electric push cylinder to enable relative sliding between it and the bottom divider 4.

[0056] Multiple top splitters 5 are arranged on the gantry 2, and their number is the same as the number of groups of bottom splitters 4; each top splitter 5 corresponds to a group of bottom splitters 4, and each top splitter 5 specifically includes:

[0057] The sliding beam 51 extends along the array direction of each group of bottom splitters 4; a travel motor or a travel trolley is provided at both ends of the sliding beam 51, so that the sliding beam 51 can slide horizontally on the gantry 2, and the sliding direction is parallel to the array direction of the slide rod 3;

[0058] The inner slide 52 is driven by an electric push cylinder on the slide beam 51 to slide horizontally, and the sliding direction is parallel to the array direction of the slide bars 3;

[0059] Two downward pressing beams 53 slide vertically on the sliding beam 51 and the inner slide 52 respectively;

[0060] Each pressing beam 53 is provided with a plurality of vertically sliding pressing blocks 54 and a spring 55 provided between the pressing blocks 54 and the pressing beam 53;

[0061] The two pressing beams 53 are driven by a pressure control mechanism. Before the blank 10 is separated, the pressure control mechanism drives the two pressing beams 53 to move downward to a first height. After the blank 10 is separated, the pressure control mechanism drives the two pressing beams 53 to move upward to a second height.

[0062] The specific working process and principle of this device are as follows:

[0063] A plurality of mutually fitting blanks 10 will be placed as a whole on a plurality of slide bars 3, with one or more slide bars 3 supporting one blank 10. Afterwards, the bottom splitter 4 and the corresponding top splitter 5 will move to the blank 10 to be split, and the fixed connector 41 and the sliding connector 42 of the bottom splitter 4 will respectively connect the slide bars 3 at the bottom of the two blanks 10. The connection can be achieved by a variety of existing technical methods such as a cylinder pushing a push block into the slide bar 3, or using an electromagnet to energize and attract the slide bar 3, which will not be described in detail here; the two lower pressing beams 53 of the top splitter 5 move downward under the drive of the pressure control mechanism, so that the two pressing blocks 54 respectively press the tops of the two blanks 10, as shown in FIG. Figure 8 As shown, the spring 55 is now in a compressed state, and the thrust generated by the spring 55 can cause the pressing block 54 to exert pressure on the blank 10, thereby achieving the clamping function of the blank 10. After clamping, the upper and lower electric push cylinders drive the sliding connector 42 and the inner slide 52 to move respectively, while the fixed connector 41 and the slide beam 51 will stop, so that one of the two blanks 10 moves and the other is fixed, thereby completing the splitting operation.

[0064] Before the two blanks 10 are broken apart, the clamping force needs to be relatively large to prevent one blank 10 from being carried away by the other blank 10 during the breaking. However, after the two blanks 10 are broken apart, only a small clamping force is required to prevent the blank 10 from tipping over during the process of moving one blank 10 to a distant place. Therefore, the pressure control mechanism will drive the two lower pressing beams 53 to move upward to the second height, such as Figure 9 As shown, the compression amount of the spring 55 will decrease at this time, and the thrust generated will reduce the pressure of the pressure block 54 on the blank 10, thereby applying only a smaller clamping force to the blank 10, avoiding damage to the blank 10 caused by a long-term large clamping force.

[0065] The pressure control mechanism can realize the switching of its mode through the traditional electric control method. However, the traditional electric control mode not only requires a variety of sensors for detecting the position, but also has high requirements for the synchronous control of the components. Once the synchronization is not achieved, it will aggravate the damage to the blank 10. In addition, a pneumatic power source is usually required to avoid excessive pressure on the blank 10 when pushing. It is not easy to control the force of the pneumatic power source by electric control. Therefore, this splitting machine proposes a pressure control mechanism in the form of a purely mechanical structure, such as Figures 7-9 Shown, including:

[0066] The first telescopic cylinder 56 has a top end hinged to the slide beam 51;

[0067] The first rotating block 57 is preferably designed to be L-shaped as a whole, with one end hinged to a lower pressure beam 53 and the other end hinged to the bottom end of the first telescopic cylinder 56, and a clamping rod 57a is provided in the middle section;

[0068] A second telescopic cylinder 58, the top end of which is hinged to the inner slide 52;

[0069] The second rotating block 59 is preferably designed to be L-shaped as a whole, with the middle section hinged to the other lower pressure beam 53, one end hinged to the bottom end of the second telescopic cylinder 58, and the other end provided with a clamping groove 59a;

[0070] The engaging groove 59a is horizontally aligned with the engaging rod 57a.

[0071] The specific working process and principle of this pressure control mechanism are as follows:

[0072] Before reaching the top of the blank 10 to be broken, Figure 7 As shown, the first telescopic cylinder 56 and the second telescopic cylinder 58 are retracted, and the clamping groove 59a will clamp the clamping rod 57a. At this time, the lower pressing beam 53 will be at the basic height H0, so that the pressing block 54 is still a certain distance from the top of the blank 10.

[0073] After reaching the top of the blank 10 to be broken, Figure 8 As shown, the first telescopic cylinder 56 and the second telescopic cylinder 58 are extended. When extended, the clamping rod 57a of the first rotating block 57 tends to rotate downward, while the clamping groove 59a of the second rotating block 59 tends to rotate upward. Since the clamping groove 59a is clamped to the clamping rod 57a before breaking apart, the rotation trends of the first rotating block 57 and the second rotating block 59 are offset, so that neither can rotate, so that the two downward pressure beams 53 are pushed downward the farthest distance to reach the first height H1. At this position, the deformation of the spring 55 is the largest, and the clamping force generated on the blank 10 is also the largest.

[0074] When the blank 10 is broken apart, as the inner slide 52 moves, the engaging groove 59a will be disengaged from the engaging rod 57a, and after disengagement, both the first rotating block 57 and the second rotating block 59 can rotate. Figure 9 As shown, at this time, the two pressing beams 53 will reach the second height H2 as the first rotating block 57 and the second rotating block 59 rotate. The deformation of the spring 55 at this position will be reduced, and the clamping force generated on the blank 10 will also be relatively reduced.

[0075] When the split is completed and reset is performed, the first telescopic cylinder 56 and the second telescopic cylinder 58 are first retracted to reset the first rotating block 57 and the second rotating block 59. Then the inner slide 52 moves to make the two lower pressing beams 53 close to each other, and finally the clamping groove 59a is clamped on the clamping rod 57a again, and the position returns to the original position. Figure 7 The status shown.

[0076] It is preferred that the hinge of the first telescopic cylinder 56 and the first rotating block 57 be designed to be aligned in the horizontal direction with the clamping rod 57a, and the hinge of the second telescopic cylinder 58 and the second rotating block 59 be designed to be aligned in the horizontal direction with the clamping rod 57a. In this way, when the clamping groove 59a is clamped with the clamping rod 57a, the two hinges and the clamping rod 57a can be on a horizontal straight line, so that the force applied by the first telescopic cylinder 56 and the second telescopic cylinder 58 can be better transmitted to the two lower pressure beams 53.

[0077] Preferably, a limit plate is provided on the lower pressure beam 53. One side of the limit plate is a horizontal plane structure, and the other side is an inclined structure. At the two extreme positions of the first rotating block 57 and the second rotating block 59, there will be a portion of the structure that fits with the two sides of the limit plate, thereby limiting the rotation angle of the first rotating block 57 and the second rotating block 59, and preventing the first rotating block 57 and the second rotating block 59 from rotating to an angle outside the design, which would cause the pressure control mechanism to fail. Preferably, a downwardly extending extension section is provided on both the first rotating block 57 and the second rotating block 59. The first rotating block 57 and the second rotating block 59 fit the horizontal plane structure of the limit plate through the extension section. The extension section needs to be provided on one side of the hinge between the two rotating blocks and the lower pressure beam 53, and on the side away from the corresponding telescopic cylinder, so that the rotation angle of the first rotating block 57 and the second rotating block 59 can be increased.

[0078] The engaging groove 59a is provided with a guide section, and the distance between the upper and lower inner walls of the guide section gradually increases in the direction toward the engaging rod 57a, so that the engaging rod 57a can enter the engaging groove 59a more conveniently when the inner slide 52 is reset.

[0079] In order to facilitate the movement of the blank 10 before and after breaking, the present breaking machine is further provided with a transport plate 6, which is used to transport the blank 10. During the breaking operation, the transport plate 6 will be placed on the intermediate frame 1;

[0080] A plurality of support beams 61 are provided in the middle of the transport plate 6. Figure 10 As shown, there is a gap between adjacent support beams 61, and during the transportation process, the blank 10 will be supported by the support beams 61;

[0081] A plurality of support blocks 31 are provided on the slide bar 3, such as Figure 11 As shown, when the transport plate 6 is placed on the intermediate frame 1, the support blocks 31 pass through the spaces between the support beams 61 and lift the blanks 10 from the support beams 61, thereby separating each blank 10 from the support beams 61 and enabling it to move along with the slide bar 3;

[0082] After the splitting is completed, the transport plate 6 can be lifted upwards so that the support beam 61 can lift the blank 10 again for transport.

[0083] In order to ensure that each blank 10 can be aligned with the corresponding slide bar 3, a rotating block 62 can be set on both sides of the conveying plate 6; the rotating block 62 is L-shaped, one end is hinged to the outer side surface of the conveying plate 6, and the other end extends from the bottom of the conveying plate 6 into the middle of the conveying plate 6 and a push roller 63 is set. A tension spring 64 is set between the rotating block 62 and the conveying plate 6, and the two ends of the tension spring 64 are respectively connected to the inner side surface of the conveying plate 6 and one end of the rotating block 62 extending into the conveying plate 6.

[0084] When the transport plate 6 is lowered onto the intermediate frame 1, Figure 12 As shown, the push rollers 63 contact the two outermost slide bars 3, forcing the slide bars 3 into contact with each other and allowing them to move to the center of the transport plate 6, thereby aligning with the respective blanks 10. When the push rollers 63 contact the slide bars 3, this causes that end of the rotating block 62 to rotate upward. However, the bottom of the transport plate 6 restrains the rotating block 62, preventing it from rotating, thereby ensuring that the push rollers 63 can push the slide bars 3. Once the transport plate 6 is placed on the intermediate frame 1, the push rollers 63 are lower than the slide bars 3, preventing them from sliding.

[0085] When the transport plate 6 is lifted upward, Figure 13 As shown, the support beam 61 first lifts the blank 10 away from the support block 31 of the slide bar 3, and then the rotating block 62 hits the slide bar 3. At this time, the end of the rotating block 62 with the push roller 63 tends to rotate downward, and the transport plate 6 does not restrict this rotation of the rotating block 62. Therefore, the rotating block 62 can rotate without affecting the lifting of the transport plate 6, and the slide bar 3 can be pushed back to the state of close contact to facilitate subsequent work. After the transport plate 6 is fully lifted, the tension spring 64 can reset the rotating block 62.

[0086] A plurality of push rollers 63 are provided, and the plurality of push rollers 63 are distributed obliquely, so that the distance between the two corresponding push rollers 63 on both sides of the conveying plate 6 in the height direction gradually increases from top to bottom. In this way, when the conveying plate 6 is lowered, the two push rollers 63 with a large spacing will first push the slide bar 3 inward, and then the two push rollers 63 with a smaller spacing will continue to push the slide bar 3 inward, and finally the slide bars 3 will reach a position where they are close to each other.

[0087] It is preferred that the multiple bottom dividers 4 located on the same side of the intermediate frame 1 are driven to move by the same power mechanism. For example, a motor can be used to simultaneously drive multiple screws to rotate through a converter, and then the bottom dividers 4 on the same side are all connected to the screws through a screw slider transmission. In this way, the multiple bottom dividers 4 can be moved synchronously to ensure that these bottom dividers 4 can be aligned with various parts of the slide rod 3 at the same time, avoiding uneven force on the slide rod 3, resulting in uneven force and damage to the blank 10 when it is broken.
