DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Example 1, refer to Figures 1-5 , the first embodiment of the present application provides a building wall demolition device which can guarantee the integrity of old bricks, including wall 1 and bearing box 2, also including demolition unit installed on bearing box 2, the demolition unit includes flat part and cutting part installed inside the bearing box 2;

[0036] The laying flat component comprises a rotating shaft 3 rotatably installed on the inner wall of the bearing box 2 on both sides, a deflection frame 4 fixedly installed on the rotating shaft 3, a plurality of connecting rods 5 fixedly installed on the inner wall of the deflection frame 4, a supporting plate 6 fixedly installed between the plurality of connecting rods 5, a support plate 7 fixedly installed on the supporting plate 6, a limiting plate 8 fixedly installed on the upper end of the deflection frame 4, a connecting plate 9 fixedly installed on one end of the limiting plate 8, a threaded hole opened on the connecting plate 9, a screw rod 10 threadedly installed on the threaded hole, a five-cornered nut 11 fixedly installed on one end of the screw rod 10, and a positioning frame 12 threadedly installed on the screw rod 10.

[0037] The fence 1 is located between the positioning frame 12 and the support plate 7, the lower end of the limiting plate 8 is tightly attached to the upper end of the fence 1, the positioning frame 12 is connected to the connecting plate 9 through the screw rod 10, the side wall of the support plate 7 is tightly attached to the side wall of the fence 1, and the inner wall of the bearing box 2 is provided with a pulling assembly.

[0038] Referring to Figure 9 and Figure 10 , the pulling assembly comprises a plurality of sliding rails 13 fixedly installed on the inner bottom wall of the bearing box 2, sliding blocks 14 slidingly installed on the sliding rails 13, pull rods 15 respectively hingedly installed on the corresponding sliding blocks 14, mounting blocks 16 respectively fixedly installed on the side walls of the connecting rods 5 and the supporting plate 6, shaft rods 17 fixedly installed on the mounting blocks 16, the shaft rods 17 being rotatably connected to one end of the corresponding pull rods 15, and a plurality of driving elements installed between the sliding blocks 14.

[0039] The driving element comprises a synchronous rod 18 fixedly installed between the side walls of the plurality of sliding blocks 14, a linkage rod 19 fixedly installed on the side wall of the synchronous rod 18, a driving box 20 fixedly installed on the side wall of the bearing box 2, a hydraulic cylinder 21 fixedly installed in the driving box 20, a push rod 22 fixedly installed on the telescopic end of the hydraulic cylinder 21, one end of the push rod 22 being fixedly connected to the linkage rod 19, and abutting plates 40 respectively fixedly installed on the two side walls of the positioning frame 12, one end of the abutting plate 40 being tightly attached to the side wall of the fence 1.

[0040] Specifically, the laying flat component has the following effects: the plurality of unit fences 1 after being divided are sequentially and slowly laid down, and the unit fence 1 is laid down and then cut in the horizontal direction, effectively avoiding the safety hazards or damage of the bricks when the construction personnel removes the bricks at a high place, improving the safety of the construction personnel when removing the wall, and facilitating the subsequent transportation of the cut bricks, effectively reducing the workload of the construction personnel. The positioning frame 12 is used for limiting and positioning the subsequent cutting, and also used for preventing the fence 1 from being laid down in the reverse direction after being cut, and when the deflection frame 4 is deflected after being divided, the unit fence 1 after being divided is driven to deflect synchronously through the positioning frame 12 and the abutting plate 40 until the wall surface is horizontal to the ground, and the laying down of the fence 1 is completed.

[0041] The positioning frame 12 is detachably mounted on the connecting plate 9 via the screw 10, which makes it easy for construction workers to install the device on the wall 1 that needs to be demolished. At the same time, after the wall 1 is demolished, the positioning frame 12 can be quickly removed and the cut bricks can be transported, which effectively improves the flexibility of the device. The overall installation is simple and quick, which effectively improves the demolition efficiency of the wall 1 by construction workers.

[0042] During use, construction workers press one end of the carrying box 2 against the side wall of the fence 1 to be demolished, and activate the hydraulic cylinder 21. The hydraulic cylinder 21 drives the push rod 22 to move horizontally through its telescopic end. During the movement of the push rod 22, multiple sliding blocks 14 move synchronously through the linkage rod 19 and the synchronizing rod 18. During the movement of the sliding blocks 14, the pull rod 15 generates a thrust on the deflection frame 4, which in turn causes the deflection frame 4 to deflect around the pivot 3, thus causing the deflection frame 4 to deflect 90° and press against the side of the fence 1. Then, the positioning frame 12 is installed on the connecting plate 9 on the deflection frame 4 through the screw 10 and further fixed with the five-corner nut 11. After the division is completed, the telescopic end of the hydraulic cylinder 21 drives the sliding block 14 to slide in the opposite direction to reset, so that when the positioning frame 12 and the deflection frame 4 deflect in the opposite direction to reset, they drive the divided wall unit to move synchronously, making the wall unit parallel to the ground.

[0043] Example 2, refer to Figures 6-8 as well as Figure 10 This is the second embodiment of the present invention, which differs from the first embodiment in that: the cutting component includes a limiting groove 23 formed on the positioning frame 12, a moving block 24 slidably mounted on the limiting groove 23, a mounting strip 25 fixedly mounted on the moving block 24, a vertical groove 26 formed on the mounting strip 25, a moving block 27 slidably mounted inside the vertical groove 26, and a first connecting plate 28 fixedly mounted on the moving block 27. The end face of the limiting groove 23 is U-shaped. A removal component is mounted on the first connecting plate 28, and a positioning component is mounted on the side wall of the positioning frame 12. The removal component includes a mounting hole formed on the first connecting plate 28, a bolt 29 threaded into the mounting hole, a second connecting plate 30 threaded onto the bolt 29, and an electric saw 31 fixedly mounted on the second connecting plate 30.

[0044] Specifically, the cutting component is used for dividing the enclosing wall 1 into a plurality of wall units, so that the construction personnel can ensure the completeness of the bricks when the enclosing wall 1 is demolished. The limiting groove 23 is arranged on the positioning frame 12, so that the construction personnel can ensure that the cutting point is a straight line when the enclosing wall 1 is cut by the electric saw 31, and the cut wall unit is regular and complete, thereby facilitating the subsequent horizontal cutting. The electric saw 31 is detachably installed on the adapter plate one 28 through the adapter plate two 30, so that the construction personnel can quickly detach the electric saw 31, and the electric saw 31 can cut the enclosing wall 1 at different positions. The adapter plate one 28 can slide in the vertical groove 26 through the moving block 27, so that the construction personnel can slide the electric saw 31 in the vertical groove 26 after the electric saw 31 is installed on the corresponding adapter plate one 28, and the electric saw 31 can enter the inside of the enclosing wall 1 to cut the enclosing wall 1.

[0045] In use, the construction personnel installs the electric saw 31 on the adapter plate one 28 through the bolt 29 and the adapter plate two 30, turns on the electric saw 31 and moves the electric saw 31 along the vertical groove 26 to the enclosing wall 1, cuts the enclosing wall 1 during the movement of the electric saw 31, and slides the electric saw 31 in the limiting groove 23. At this time, the electric saw 31 cuts the enclosing wall 1, and the cut wall unit is equal to the shape of the limiting groove 23 during the cutting. When the electric saw 31 cuts along the limiting groove 23 and is completed, the cutting of the enclosing wall 1 is completed.

[0046] The remaining structure is the same as that of the first embodiment.

[0047] Embodiment 3, refer to Figures 2-3 This is the third embodiment of the present application, which is different from the second embodiment: the two side walls of the positioning frame 12 are provided with side wall grooves 32, a positioning rod 33 is slidably installed between the two side wall grooves 32, a horizontal groove 34 is arranged on the positioning rod 33, a positioning block 35 is slidably installed in the horizontal groove 34, a moving groove is arranged on the positioning block 35, an adapter plate three 36 is slidably installed in the moving groove, and a fixing element is installed on the side wall of the positioning rod 33. The fixing element comprises a square plate 37 fixedly installed on the side wall of the positioning rod 33, a circular hole arranged on the square plate 37, a fixed threaded rod 38 threadedly installed in the circular hole, and a rubber ring 39 sleevedly installed on one end of the fixed threaded rod 38.

[0048] Specifically, the positioning rod 33 is used to position the cutting point of the electric saw 31 at the joint between the two adjacent bricks when cutting the laid wall unit, so that when the worker pushes the electric saw 31 to slide in the horizontal groove 34, the cutting point can cut along the joint, and the wall unit is cut into a strip composed of multiple bricks, and then the worker can quickly cut the strip-shaped wall into individual bricks. The fixing assembly is used to fix the positioning rod 33 at the positioning point, so that when the worker pushes the electric saw 31 to slide in the horizontal groove 34, the positioning rod 33 does not move, so that the cutting point is not a straight line. By rotating the fixing threaded rod 38, the end of the fixing threaded rod 38 sleeved with the rubber ring 39 is tightly attached to the abutting plate 40, so that the positioning rod 33 is in a fixed state, and the stability during cutting is improved.

[0049] In use, when the divided wall unit is laid down, the worker installs the electric saw 31 on the adapter plate 36 and adjusts the positioning rod 33 so that the cutting point of the electric saw 31 is at the joint between the two adjacent bricks. After the position is adjusted, the electric saw 31 is turned on and pressed downward, so that the electric saw 31 cuts the wall unit. The worker pushes the electric saw 31 to slide in the horizontal groove 34, so that the electric saw 31 cuts the joint between the bricks and cuts the wall unit into a strip. Then the worker takes out the strip-shaped wall and cuts the strip-shaped wall in the vertical direction in turn and divides it into multiple bricks. While the fence 1 is removed, the bricks are completely preserved, which facilitates the reuse of the bricks.

[0050] Therefore, with reference to Figures 10-12 , the present application avoids the safety risk of brick falling and damage when demolishing the wall at a high place, and can orderly demolish according to the stacking method of the bricks during stacking of the wall. During the construction of the wall, the worker usually stacks the bricks in an alternating manner according to the upper and lower adjacent bricks to ensure the stability of the overall wall. This makes it difficult for the worker to cut the upper and lower adjacent bricks in a straight line in the vertical direction when using the electric saw to cut and demolish them. Therefore, after the fence 1 is laid down, the positioning assembly is used to position the joint of each layer of bricks, and then the wall unit is cut into multiple strips in the horizontal direction. After cutting, the worker cuts the strip-shaped wall in the vertical direction to further divide the strip-shaped wall into individual bricks. When demolishing the wall, the worker can protect most of the bricks from damage, which facilitates the reuse of the bricks. The orderly cutting can improve the efficiency of the worker during the demolition of the wall and improve the quality of the wall demolition.

[0051] The remaining structure is the same as that of embodiment 2.

[0052] In combination with the embodiments 1-3, the working principle of the present application is as follows: the construction personnel abut one end of the bearing box 2 to the side wall of the wall to be demolished, open the hydraulic cylinder 21, the hydraulic cylinder 21 drives the push rod 22 to move in the horizontal direction through the telescopic end, the push rod 22 drives the plurality of sliding blocks 14 to move synchronously through the linkage rod 19 and the synchronous rod 18 in the movement process, the sliding blocks 14 generate a pushing force on the deflection frame 4 through the pull rod 15 in the movement process, further drive the deflection frame 4 to deflect around the pivot shaft 3, further make the deflection frame 4 abut the side of the wall 1 after deflection of 90°, then install the positioning frame 12 on the connecting plate 9 on the deflection frame 4 through the screw rod 10, and further fix it through the five-angle nut 11.

[0053] The construction personnel install the electric saw 31 on the adapter plate one 28 through the bolt 29 and the adapter plate two 30, open the electric saw 31 and move the electric saw 31 along the vertical slot 26 to the wall 1, the electric saw 31 cuts the wall 1 in the movement process, and pushes the electric saw 31 to slide in the limiting slot 23, at this time the electric saw 31 cuts the wall 1, and the cut wall unit is equal to the shape of the limiting slot 23 when cutting, when the electric saw 31 cuts along the limiting slot 23, the cutting of the wall 1 is completed.

[0054] After the cutting is completed, the sliding blocks 14 are driven by the telescopic end of the hydraulic cylinder 21 to slide reversely to reset, so that the positioning frame 12 and the deflection frame 4 drive the cut wall unit to move synchronously when resetting reversely, so that the wall unit is parallel to the ground.

[0055] When the cut wall unit is laid down, the construction personnel install the electric saw 31 on the adapter plate three 36, and adjust the positioning rod 33 so that the cutting point of the electric saw 31 is at the connecting point between the adjacent two bricks, after the position adjustment is completed, open the electric saw 31 and press the electric saw 31 downward, so that the electric saw 31 cuts the wall unit, the construction personnel push the electric saw 31 to make the electric saw 31 slide in the horizontal slot 34, so that the electric saw 31 cuts the connecting part of the bricks, and the wall unit is cut into strips, then the construction personnel take out the strip-shaped wall, cut the strip-shaped wall in the vertical direction in turn, and cut into a plurality of bricks, while the wall 1 is demolished, the bricks are completely retained, which is convenient for the reuse of the bricks.
