The interlocking blocks of the yard need to be repaired. Due to foundation settlement and vehicle crushing, the new and old joints and the edge parts of the site cannot fit effectively, and the shape of the interlocking blocks needs to be cut.

[0003] At present, a brick cutting device (such as publication number CN210500871U) has appeared, which is provided with upper and lower blades. The upper blade is fixed, and the lower blade is fixedly set on a working platform. The working platform rises under the action of a jack to cut the brick body. The working platform includes a support plate, which is fixedly connected to the lower blade. The support plate can be used to support the brick body during the cutting process to avoid hand-held brick cutting.

[0004] The existing brick cutting device for avoiding hand-held bricks makes the top of the lower blade not higher than the upper surface of the working platform. Although the brick can be placed stably on the working platform, the lower blade cannot play a cutting role during the cutting process. The cutting of the brick depends on the force between the upper blade and the working platform. The required cutting force is large, which is not convenient for cutting the brick and is very likely to cause damage to the upper blade and the working platform. Utility Model Content

[0022] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] In a typical implementation of the present invention, Figure 1-Figure 3 As shown, an interlocking block cutting device is proposed, comprising: a base 1, a bracket 4 and a lifting mechanism are fixedly installed on the base 1, wherein an upper cutter 5 is fixedly installed on the bracket 4, the blade of the upper cutter 5 is downward, the lifting mechanism is a jack 2, a lower cutter 6 is fixedly installed on the top of the telescopic rod of the jack 2, the blade of the lower cutter 6 is upward, and the lower cutter 6 is located directly below the upper cutter 5, and the bottoms of both ends of the lower cutter 6 are connected to the base 1 through springs 8, so that the lower cutter 6 can be driven by the jack 2 to move upward to cooperate with the upper cutter 5 to achieve cutting of the interlocking block.

[0024] like Figure 1 The bracket 4 includes two columns and a cover plate. The two columns are relatively vertically fixed on the base 1. The cover plate is buckled on the top of the two columns to connect the tops of the two columns. The lower cutter 6 is located between the two columns, and the two ends of the lower cutter 6 are slidably connected to the adjacent columns. At the same time, a support plate 7 is also slidably provided between the two columns. The support plate 7 is located directly above the lower cutter 6 and directly below the upper cutter 5. The two ends of the support plate 7 are slidably connected to the adjacent columns. After moving into place, the two ends of the support plate 7 are fixedly connected to the columns by bolts 9.

[0025] Specifically, a first guide groove 11 and a second guide groove 12 are vertically opened on the inner side wall of each column, wherein one first guide groove 11 is provided, and the first guide groove 11 is vertically opened at the middle position of the inner side wall of the column, and two second guide grooves 12 are provided, and the two second guide grooves 12 are relatively distributed on both sides of the first guide groove 11, and the two ends of the lower cutter 6 are slidably set in the first guide groove 11 on the columns on both sides, and the two ends of the support plate 7 are slidably set in the second guide groove 12 on the columns on both sides, and the middle part of the support plate 7 is vacant, and the lower cutter 6 is located directly below the vacancy in the middle of the support plate 7, and the blade part of the lower cutter 6 can pass through the support plate 7 upward from the middle vacancy to cooperate with the upper cutter 5 to cut the interlocking block.

[0026] like Figure 2As shown, the support plate 7 includes a support portion 72, two ends of the support portion 72 are respectively fixed with two legs 71, the legs 71 are slidably arranged in the second guide groove 12, and play a role of limiting and guiding, and the cross-sections of the second guide groove 12 and the legs 71 are both rectangular;

[0027] The support portion 72 is located between the two columns and is used to support the interlocking block during the cutting process. There is no need to manually hold the interlocking block, which improves the safety of the cutting process. The support portion 72 is a plate-like structure, and a rectangular opening 74 is opened in the middle position of the support portion 72. The opening 74 can allow the blade of the lower cutter 6 to pass through.

[0028] It is understandable that the width of the support portion 72 can be set according to demand, as long as it can meet the support requirements for the interlocking block, and no excessive restrictions are made here.

[0029] like Figure 3 As shown, the lower cutter 6 includes a mounting seat 61 and a blade portion 62. The mounting seat 61 is a rectangular plate-shaped structure. The mounting seat 61 is fixedly arranged on the top of the telescopic rod of the jack 2. The two ends of the mounting seat 61 are slidably arranged in the first guide grooves 11 of the columns on both sides thereof. The blade portion 62 is fixedly arranged on the mounting seat 61. The length of the blade portion 62 is smaller than the mounting seat 61, and the blade portion 62 is located directly below the through opening 74 on the support plate 7. The length and width of the blade portion 62 are not greater than the length and width of the through opening 74. The thickness of the blade portion 62 is slightly greater than the thickness of the support plate 7 (it can also be understood as the thickness of the through opening 74). Therefore, when the lower cutter 6 moves upward under the drive of the jack 2, the support plate 7 can avoid obstruction to the lower cutter 6, so that the blade portion 62 passes through the support plate 7 to cooperate with the upper cutter 5 to achieve the cutting of the interlocking block.

[0030] It is understandable that the thickness of the blade portion 62 only needs to be able to ensure that it can pass through the support plate 7 upwards and contact the bottom of the interlocking block, and it does not need to extend too much, as long as it can ensure that the blade can contact the bottom of the interlocking block.

[0031] Since the support plate 7 needs to support the interlocking block, the support plate 7 needs to be fixed after adjusting the position, such as Figure 1-Figure 2 As shown, a plurality of mounting holes 10 are provided on the two upright posts of the bracket 4 at vertical intervals, and the mounting holes 10 pass through the second guide groove 12 for installing the bolts 9. A through hole 73 is provided on the leg 71 of the support plate 7. When positioning is required, the bolt 9 is passed through the mounting hole 10 and the through hole 73 in sequence to achieve a fixed connection between the support plate 7 and the bracket 4.

[0032] The jack 2 comprises a pressure rod 3 , through which the movement of the telescopic rod of the jack 2 can be controlled.

[0033] The specific working principle is:

[0034] Place the interlocking block on the support plate 7 so that the position of the interlocking block to be cut is located directly above the through opening 74 of the support portion 72;

[0035] Then adjust the position of the support plate 7 according to the thickness of the interlocking block so that the top of the interlocking block to be cut contacts the blade of the upper cutter 5. When the support plate 7 is adjusted into place, tighten the bolt 9 to fix the position of the support plate 7.

[0036] The pressure rod 3 is manually operated to control the telescopic rod of the jack 2 to extend upward, thereby driving the lower cutter 6 to move upward and stretching the spring 8. The blade portion 62 of the lower cutter 6 passes through the through opening 74 at the middle position of the support plate 7 and extends upward. The blade portion 62 of the lower cutter 6 contacts the bottom of the interlocking block at the cutting position. Through the cooperation of the upper cutter 5 and the lower cutter 6, the cutting of the interlocking block is achieved, the telescopic rod is controlled to be retracted, and the lower cutter 6 is quickly reset under the action of the spring 8.

[0037] In this embodiment, during the cutting operation, the interlocking block is supported by the support plate 7. The support plate 7 cooperates with the upper cutter 5 to limit the interlocking block without manual support, which effectively reduces the operation risk. The support plate 7 can adjust the position vertically and is suitable for interlocking blocks of different thicknesses. The setting of the through port 74 and the lower cutter 6 structure can facilitate the contact between the blade 62 of the lower cutter 6 and the bottom of the interlocking block without being blocked by the support plate 7. The coordinated use of the upper cutter 5 and the lower cutter 6 effectively reduces the force area of ​​the interlocking block at the cutting position, and can quickly cut the interlocking block with a small cutting force.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
