[0046] The present invention is illustrated below with specific embodiments, but these are not intended to limit the invention.

[0047] Example 1

[0048] like Figures 1-10 As shown in this embodiment, a vertical cutting device for concrete blocks is provided, including a movable frame 1. The movable frame 1 is supported by a bracket 10 and a lifting frame 11 above the conveyor line 9 for conveying concrete blocks. That is, the bracket 10 is fixed on the conveyor line 9. The bracket 10 includes four vertical columns and a top plate. The four corners of the lifting frame 11 are sleeved on the columns of the bracket 10. The top plate is also provided with a drive mechanism for driving the lifting frame 11 to move up and down. The movable frame 1 is horizontally arranged inside the lifting frame 11. A cylinder 12 is fixed on the lifting frame 11. The output shaft of the cylinder 12 is connected to the movable frame 1 to control the movable frame 1 to move back and forth left and right inside the lifting frame 11.

[0049] For example, the drive mechanism includes a motor, a suspension rope, and a roller for winding the suspension rope. The end of the suspension rope is connected to the lifting frame 11. The motor controls the winding roller to wind up the suspension rope, thereby controlling the length of the suspension rope as it unfolds, and thus driving the lifting frame 11 to rise and fall.

[0050] Two rows of support seats 2 are symmetrically arranged on the mobile frame 1. The two rows of support seats 2 correspond one to one. A steel tangent 4 is arranged horizontally between each pair of corresponding support seats 2. Multiple steel tangent 4 are tensioned in parallel on the mobile frame 1. When the lifting frame 11 moves up and down on the support 10, the mobile frame 1 moves up and down with the steel tangent 4. At the same time, the cylinder 12 drives the mobile frame 1 to move back and forth with the steel tangent 4, thereby realizing the vertical cutting of concrete blocks.

[0051] The support base 2 is rotationally connected with a tensioning column 3, and the end of the tensioning column 3 is provided with a clamping assembly 5 for clamping the end of a steel cutting line 4. The steel cutting line 4 is coaxially arranged with the tensioning column 3, and rotates along its own axis when the tensioning column 3 rotates on the support base 2. The support base 2 is fixedly installed with a fixed sleeve 7, and the fixed sleeve 7 is sleeved with a buffer sleeve 6. The end of the tensioning column 3 away from the clamping assembly 5 penetrates through the fixed sleeve 7 and is fixedly connected with an abutting plate 301. The end face of the buffer sleeve 6 close to the abutting plate 301 is axially arrayed with a plurality of top pressing blocks 601, as shown in FIG. 1. The side wall of the fixed sleeve 7 is provided with a plug-in groove 701 matched with the top pressing blocks 601. After the buffer sleeve 6 is sleeved on the fixed sleeve 7, each top pressing block 601 is plugged into the plug-in groove 701, so as to limit the axial rotation of the buffer sleeve 6 on the fixed sleeve 7. The top pressing block 601 is rotationally connected with a ball 602 for supporting the abutting plate 301. After the top pressing block 601 is plugged into the plug-in groove 701, the ball 602 penetrates through the side wall of the plug-in groove 701 and contacts with the side wall of the abutting plate 301. Figure 6

[0052] In order to control the rotation of the tensioning column 3, two synchronously rotating worms 13 are arranged on the moving frame 1 corresponding to the two rows of support bases 2 (a motor for driving the worms 13 to rotate is arranged on the moving frame 1, and the motor is a prior art product, so it is not shown in the figure). The abutting plate 301 is fixedly provided with a driven gear 14, which is meshingly connected with the worm 13 on the same side. When the worm 13 rotates, the worm 13 rotates with the abutting plate 301 and the tensioning column 3, thereby driving the steel cutting line 4 to rotate during cutting. The rotation of the steel cutting line 4 can disperse the wear of the steel cutting line 4 and slow down the problem of local rapid wear.

[0053] The installation process of the support base 2, the tensioning column 3, the abutting plate 301, the buffer sleeve 6 and the fixed sleeve 7 is as follows:

[0054] Firstly, the buffer sleeve 6 is sleeved on the fixed sleeve 7, the top pressing block 601 is plugged into the plug-in groove 701, and the ball 602 is exposed from the plug-in groove 701;

[0055] Then, the fixed sleeve 7 sleeved with the buffer sleeve 6 is fixed on the support base 2, and the end of the tensioning column 3 away from the abutting plate 301 is sleeved in the fixed sleeve 7;

[0056] Finally, the abutting plate 301 is fixed on the tensioning column 3. After the abutting plate 301 is fixed on the tensioning column 3, the ball 602 abuts against the side wall of the abutting plate 301. When the tensioning column 3 rotates in the fixed sleeve 7, the ball 602 rolls relative to the abutting plate 301 to support the abutting plate 301 and the tensioning column 3, which is conducive to the rotation of the tensioning column 3.

[0057] In addition, a bearing is sleeved in the inner ring of the fixed sleeve 7, so as to further improve the smoothness of the rotation of the tensioning column 3.​

[0058] Embodiment two

[0059] As shown in Figure 3 , Figure 5 , based on embodiment one, in order to connect the end of the steel cutting line 4, the clamping assembly 5 comprises a connecting block 501 connected to the end of the tensioning column 3; an outer conical shell 502 is fixed to the side wall of the connecting block 501, and a conical cavity 503 is formed in the inner front end of the outer conical shell 502; a conical core 506 is arranged in the inner part of the outer conical shell 502, and a conical wall 504 is arranged on the side wall of the conical core 506 to clamp the steel cutting line 4 in cooperation with the conical cavity 503, and a through hole 505 is formed in the side wall of the conical core 506 for the steel cutting line 4 to pass through.

[0060] The process of clamping the steel cutting line 4 by the clamping assembly 5 is as follows:

[0061] The end of the steel cutting line 4 is inserted into the front end of the outer conical shell 502, and then the end of the steel cutting line 4 is connected to the through hole 505 of the conical core 506, and then the end of the steel cutting line 4 is pulled out from the rear end of the outer conical shell 502, and in this state, the conical core 506 is inserted into the outer conical shell 502 from the rear end of the outer conical shell 502, and in this state, the steel cutting line 4 is clamped between the inner wall of the conical cavity 503 and the conical wall 504.

[0062] When tension is applied to the whole steel cutting line 4, the tension of the steel cutting line 4 acts on the conical core 506, and at this time, the inner wall of the conical cavity 503 and the conical wall 504 clamp the steel cutting line 4 more tightly, thereby improving the stability of clamping the steel cutting line 4.

[0063] A spring 507 is arranged between the connecting block 501 and the conical core 506 for springing the conical core 506, as shown in Figure 3 , Figure 5 , during the process of fixing the outer conical shell 502 to the connecting block 501, one end of the spring 507 abuts against the side wall of the connecting block 501, and the other end abuts against the side wall of the conical core 506, and at this time, through the springing of the spring 507, the conical core 506 can be springed towards the inner cavity front end of the outer conical shell 502, thereby increasing the stability of clamping the steel cutting line 4.

[0064] A bolt column 508 is fixed to the connecting block 501, a threaded hole 302 adapted to the bolt column 508 is formed in the end of the tensioning column 3, and a locking bolt 303 is arranged on the side wall of the tensioning column 3, the threaded end of the locking bolt 303 penetrates through the side wall of the tensioning column 3 and movably abuts against the side wall of the bolt column 508, and the bolt column 508 is screwed into the inner part of the threaded hole 302, thereby fixing the connecting block 501 to the tensioning column 3.

[0065] When the tapered wall 504 of the tapered core 506 is matched with the tapered cavity 503 of the outer tapered shell 502 to clamp the steel cutting line 4, the bolt column 508 is screwed into the threaded hole 302, the clamping assembly 5 moves towards the tensioning column 3, which can play a role in tensioning the steel cutting line 4. After the steel cutting line 4 is tensioned, the locking bolt 303 is tightened, so that the threaded end of the locking bolt 303 presses on the side wall of the bolt column 508. At this time, the bolt column 508 is fixed in the threaded hole 302, that is, the steel cutting line 4 is in a tensioned state.

[0066] Example three

[0067] As shown in Figure 4 , Figure 7 , Figure 10 based on example one, in order to effectively buffer the cutting of the steel cutting line 4, a lubricating cavity 603 is opened in the inside of the pressing block 601, an oil hole 604 is opened on the pressing block 601 for the ball 602 to contact the oil in the lubricating cavity 603, a ball groove 607 is opened in the inside of the pressing block 601 for accommodating the ball 602, the mouth of the ball groove 607 is fixed with a retainer 608 for limiting the ball 602 in the ball groove 607, the ball groove 607 is communicated with the lubricating cavity 603 through the oil hole 604, and the oil can flow from the lubricating cavity 603 to the inside of the ball groove 607. When the ball 602 rotates in the inside of the ball groove 607, a layer of lubricating oil film is formed on the surface of the ball 602, which can improve the smoothness of the ball 602 rolling on the pressing plate 301.

[0068] The inside of the buffer sleeve 6 is provided with an oil supply cavity 605 corresponding to the lubricating cavity 603, the buffer sleeve 6 is provided with an oil injection pipe 606 connected with an external oil supply system, the end of the buffer sleeve 6 away from the pressing block 601 is fixed with a buffer pad 8, the end of the buffer pad 8 close to the buffer sleeve 6 is fixed with a plurality of tapered heads 801 for plugging the end of the oil supply cavity 605, the outer contour of the buffer pad 8 is provided with a ring groove 802, the ring groove 802 is communicated with the oil injection pipe 606, the inside of the buffer pad 8 is provided with a plurality of oil channels 803, the plurality of oil channels 803 correspond to the tapered heads 801 and the oil supply cavities 605 one by one, and the ring groove 802 is communicated with each oil supply cavity 605 through the oil channels 803, as shown in Figure 4 , Figure 7 the number of oil channels 803 corresponds to the number of oil supply cavities 605.

[0069] In addition, the buffer pad 8 and the tapered head 801 can be made of rubber material. Since the buffer pad 8 is arranged between the buffer sleeve 6 and the support seat 2, when axial vibration is encountered during cutting, the buffer pad 8 buffers the buffer sleeve 6 through the top pressing block 601, the ball 602 and the abutting plate 301 to buffer the tensioning column 3, that is, the steel cutting line 4 plays a buffering role during cutting. During the buffering process, when the buffer pad 8 is deformed and compressed, the tapered head 801 will move towards the oil supply cavity 605 (the movement is slight, and after the buffering force is eliminated, the buffer pad 8 and the tapered head 801 are reset). At this time, the tapered head 801 can extrude the oil in the oil supply cavity 605 towards the lubricating cavity 603, so that the oil in the lubricating cavity 603 flows in and out of the oil hole 604 and is coated on the ball 602, thereby improving the lubricating effect.

[0070] The tapered head 801 is in the shape of a truncated cone, the oil channel 803 penetrates the tapered head 801 along the axis of the tapered head 801, and the oil supply cavity 605 is arranged at the port portion close to the buffer pad 8 in a trumpet shape matched with the tapered head 801.

[0071] When the tapered head 801 moves towards the oil supply cavity 605, the tapered head 801 is limited to shrink and deform by the trumpet-shaped port of the oil supply cavity 605, so that the oil channel 803 shrinks. When the oil in the oil supply cavity 605 is extruded towards the lubricating cavity 603, the shrinkage of the oil channel 803 can reduce the backflow of the oil in the oil supply cavity 605 from the oil channel 803, increase the amount of oil flowing from the oil supply cavity 605 to the lubricating cavity 603, and further improve the lubricating effect.

[0072] The lubricating cavity 603 and the oil supply cavity 605 are filled with a sponge layer that absorbs oil. The function of the sponge layer absorbing oil can make the inner cavities of the lubricating cavity 603 and the oil supply cavity 605 full of oil.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present application can still be modified or equivalently replaced without departing from the spirit and scope of the present application. Any modification or partial replacement should be covered in the scope of the claims of the present application.
