Description

Technical Field

[0002] In the secondary structure project of building construction, the construction of the infill wall masonry project is the key line, and its construction progress and quality are of utmost importance. During the construction process of infill wall masonry, in order to improve efficiency, reasonable equipment or tools are generally selected. For example, in the construction where aerated concrete blocks require specific dimensions, in order to improve efficiency, TL-30 type aerated block brick cutting equipment is generally used. This equipment is widely used in the infill wall masonry project. However, the prerequisite for using this equipment is generally that an open working surface is required to facilitate placing the equipment and the construction workers to carry the aerated concrete blocks to the equipment for cutting. In the construction of infill wall masonry with a small working surface (such as a pipe well), the cutting equipment generally selected is a manual aerated block brick cutting machine, which can complete cutting in a small working surface.

[0003] However, both of the above two types of equipment have certain limitations during the block cutting process. For example, during the use of the TL-30 type aerated block brick cutting machine, it is not suitable to be selected if the following situations exist at the construction site: the cutting working surface is far from the construction location. The manual aerated block brick cutting machine uses manual pressing of the connecting rod as power, and it has the following limitations: it must be carried by hand or carried by multiple people during handling. Moreover, they also have a common limitation: they cannot perform diagonal cutting on aerated blocks.

[0004] In summary, neither of the above two types of equipment is suitable for a large number of cuts of specific-shaped blocks in the construction of infill walls with a small working surface. Content of the Utility Model

[0029] Embodiment:

[0030] As Figure 1 、 Figure 2 shown, this embodiment provides a quick-positioning block cutting machine, including a bottom plate platform 1. On the left and right sides of the rear part of the bottom plate platform 1, a T-shaped frame support plate 2 is respectively installed. The T-shaped frame support plate 2 includes an upper vertical plate and a lower horizontal plate. An upper knife vertical slot 3 is provided on the upper side of the upper vertical plate, and a lower knife vertical slot 4 is provided on the lower side. An upper blade 5 is installed between two upper knife vertical slots 3, and a lower blade 6 is installed between two lower knife vertical slots 4. The upper blade 5 can move up and down along the upper knife vertical slot 3, and the lower blade 6 can move up and down along the lower knife vertical slot 4.

[0031] In a further specific embodiment, a positioning support plate 15 and a positioning support rod 16 for ensuring the stable connection of the two T-shaped frame support plates 2 are connected between the two upper vertical plates.

[0032] A rotating shaft 7 is installed between the upper knife vertical slots 3 at the upper parts of the two upper vertical plates. An operating rod 8 is connected to the middle of the rotating shaft 7. The two ends of the rotating shaft 7 pass through the corresponding upper knife vertical slots 3 and are respectively eccentrically connected with a hinge joint 9. A linkage rod 10 is provided on the outer side of the upper vertical plate. The upper end of the linkage rod 10 is hinged to the corresponding hinge joint 9, and the lower end is hinged to the outer end of the lower blade 6.

[0033] The linkage rod 10 is a key component for connecting the lower blade 6. When pressing the operating rod 8, the linkage rod 10 provides an upward force to the lower blade 6, enabling the lower blade 6 and the upper blade 5 to cooperate together to improve the cutting efficiency. The specific process is as follows: By controlling the operating rod 8 to drive the rotation of the rotating shaft 7, the hinge joints 9 at both ends of the rotating shaft 7 can be driven to rotate. Since the hinge joints 9 are eccentrically fixed on the rotating shaft 7, the hinge joints 9 can drive the lower blade 6 to move up and down through the linkage rod 10 to complete the brick cutting function, making the brick cutting more efficient and labor-saving.

[0034] The up-and-down position of the upper blade 5 is adjusted by a blade adjusting mechanism installed between the two upper vertical plates, enabling the instrument to be applicable to various block cuttings.

[0035] Specifically, the blade adjustment mechanism includes a mounting rod 18, which is connected to the upper part between the two upper vertical plates. A vertical screw barrel 19 is fixed to the middle position of the mounting rod 18. A blade adjustment rod 20 with an external thread is screwed into the vertical screw barrel 19. The bottom end of the blade adjustment rod 20 is fixedly connected to the upper blade 5. By rotating the blade adjustment rod 20 to make it move up and down relative to the vertical screw barrel 19, the upper and lower positions of the upper blade 5 can be adjusted.

[0036] Furthermore, a through hole 1 is provided on the vertical screw barrel 19, and several through holes 2 are vertically arranged on the blade adjustment rod 20. The positioning pin passes through the through hole 1 and the corresponding through hole 2 in sequence to position the upper and lower positions of the blade adjustment rod 20, ensuring that the upper blade 5 will not move up and down after being positioned.

[0037] A scale 11 is longitudinally arranged at the left end or the right end of the upper surface of the base platform, and the rear end of the scale 11 is hinged to the base platform 1, so that the scale 11 can move freely in the area above the base platform 1. At the same time, the scale 11 is restricted from rotating in the direction away from the base platform 1 when it is in the longitudinal state. Therefore, the scale 11 can be against the side of the block when the block is cut at a right angle, and it is convenient for the staff to intuitively determine the cutting size, reduce the use of tape measures to measure the size and draw positioning lines, and enhance the cutting construction efficiency.

[0038] The upper surface of the base platform 1 is provided with a 45° positioning hole 13 and a 30° positioning hole 14 into which a positioning pin 12 can be inserted, and a scale positioning hole adapted for the positioning pin 12 is provided at a corresponding position on the scale 11. The scale positioning hole can be rotated to coincide with the 45° positioning hole 13 or the 30° positioning hole 14 to temporarily fix the inclined scale 11.

[0039] The 45° positioning hole 13 and the 30° positioning hole 14 are holes for positioning and fixing the positioning pin 12 when cutting the 45° angle and 30° angle building blocks.

[0040] In a further specific embodiment, a roller 17 is installed at the rear end of each of the two lower horizontal plates to facilitate the transportation of the device after folding.

[0041] In a further specific embodiment, an array of rectangular wheel holes is provided on the upper surface of the base platform 1, and two horizontally and laterally arranged rectangular wheel holes form a group. An axle rod is installed at the bottom of the base platform 1 relative to each group of rectangular wheel holes, and bearings 21 are installed on both sides of the axle rod. The upper half of the wheel body of the bearing 21 protrudes from the rectangular wheel hole to the outside of the upper surface of the base platform 1.

[0042] The utility model supports the building blocks by installing a plurality of bearings 21 on the upper surface of the bottom plate platform 1, which can effectively reduce the friction between the building blocks and the bottom plate platform 1, so that the staff can push the bricks more easily.

[0043] In a further specific embodiment, the left and right sides of the rear part of the bottom plate platform 1 are respectively hinged to the corresponding lower cross plates, and the bottom plate platform 1 can be rotationally folded relative to the T-shaped frame support plate 2 through the hinge points.

[0044] Furthermore, one side of the bottom plate platform 1 is also provided with a fixing pin hole with a folding fixing pin, the upper vertical plate is provided with a positioning hole, and the lower cross plate is provided with a limiting groove 22 and a transverse adjustment hole 23; when the bottom plate platform 1 is unfolded for work, the folding fixing pin can be clamped in the limiting groove 22, and the bottom plate platform 1 can be adjusted back and forth along the transverse adjustment hole 23, and the limiting groove 22 can make its operation more stable when the cutting machine is working; when folding, the fixing pin hole and the positioning hole are connected by the folding fixing pin, and the folded bottom plate platform 1 can be fixed to the T-shaped frame support plate 2.

[0045] This practical confidence cutting machine can be folded when not in use, which is convenient for transportation and reduces the occupied space.

[0046] In a further specific embodiment, the operating rod 8 is detachably installed on the rotating shaft 7. The detachable operating rod 8 can reduce the transportation space of the cutting machine and make it more convenient to carry.

[0047] As Figure 3 shown, during the construction process of the present utility model, if it is desired to cut special-sized building blocks with 45° angles and 30° angles, then only need to insert the positioning pin 12 into the designated positioning hole (45° positioning hole 13 or 30° positioning hole 14). Both the 45° positioning hole 13 and the 30° positioning hole 14 are 8 mm in diameter and have internal threads machined in the holes. The positioning pin 12 is a stainless steel cylinder, and one end of the positioning pin 12 has external threads to be adaptively connected to the 45° positioning hole 13 or the 30° positioning hole 14; the building block is placed on the bottom plate platform 1, the side of the building block abuts against the side of the positioning pin 12, and the top corner of the building block abuts against the scale 11, so that an angle of 30° or 45° can be formed with the cutter head. If a right angle is to be cut, only the side of the building block needs to abut against the scale 11 to position and fix the building block; after fixing, adjust the blade adjusting rod 20 to adjust the position of the upper blade 5; press down the operating rod 8, drive the linkage rod 10 to move upward, and at the same time, the linkage rod 10 drives the lower blade 6 to move upward together to cooperate and quickly cut the building block.

[0048] After the tool is used up, first remove the folding fixing pin, then fold the tool and then insert the folding fixing pin into the fixing pin hole and the positioning hole to save storage space, and the rollers 17 facilitate the pushing of this cutting machine.

[0049] The equipment of the utility model has the characteristics of low cost, high efficiency, portability, economy and practicality, simple operation, safety, etc., which can effectively improve the construction efficiency of obliquely cutting blocks, ensure the project quality, reduce the labor intensity of workers, and accelerate the project construction progress.
