[0039] Referring to Figure 1 , Figure 2 and Figure 4 The utility model embodiment provides a building dismantling device, including: dismantling assembly 100, cutting assembly 200, hoisting frame 300 and hoisting assembly 400.

[0040] Among them, the dismantling assembly 100 includes the dismantling platform 110 that can be lifted along the height direction of the building;The dismantling platform 110 is pre-assembled at the bottom of the building, and has lifting cable, and one lifting limiting piece is arranged at each floor of the building to limit the lifting cable, after the dismantling platform 110 is assembled, the dismantling platform 110 is lifted by the lifting cable, and the lifting limiting piece can also prevent the sudden falling of the dismantling platform 110. The outer peripheral surface of the dismantling platform 110 can also be provided with an anti-falling net to prevent parts or building waste from falling. Among them, it should be noted that the specific structure of the lifting cable and the lifting limiting piece is widely used in the field of building, for example, when building high-rise buildings, the lifting cable and the lifting limiting piece structure are used, and the specific structure of the lifting cable and the lifting limiting piece is not described here.

[0041] The cutting assembly 200 is arranged on the dismantling platform 110 and is used for dismantling the components of the building according to the assembly shape of the building components;The cutting assembly 200 is arranged on the dismantling platform 110 and moves together with the dismantling platform 110, so that the cutting assembly 200 moves to the top of the building, and the cutting assembly 200 starts the dismantling operation from the top of the building. For example, when the building needs to be dismantled beam, the cutting assembly 200 cuts the two ends of the beam, so that the main body of the beam is preserved intact, the beam is basically kept intact along the length direction, and the beam can be used in a new construction site.

[0042] The hoisting frame 300 is arranged along the height direction of the building and is arranged at intervals along the circumference of the building and the demolition platform 110, and a demolition passage for passing the components is formed between the hoisting platform and the demolition platform 110. The hoisting assembly 400 is arranged at the top of the hoisting frame 300, and the hoisting assembly 400 can hoist the components removed from the top of the building to the ground. After the beams or columns of each floor of the building are removed, the ropes are bound to the outer circumferential surface of the components to fix the beams or columns, and the hoisting assembly 400 is hoisted. After the components are hoisted, the components are moved from the top of the building to the ground through the demolition passage, wherein the length direction of the beams or columns is generally the same as the height direction of the building during hoisting. The hoisting frame 300 is more convenient for transferring the components at the interval between the hoisting frame 300 and the demolition platform 110. The hoisting frame 300 itself does not hinder the hoisting of the components, and is more convenient to use. The hoisting assembly 400 is a cantilever crane.

[0043] It is worth understanding that the demolition assembly 100 climbs along the outer surface of the building, the cutting assembly 200 moves to the top of the building, and the components of the building are cut, so that the components of the building can be separated from the main body of the building in a substantially complete state, and after separation, the components are hoisted by the hoisting assembly 400 along the height direction of the building to the ground to transfer the components, and then the components can be used to other construction sites, saving production costs, and the components are fully utilized, and the cost of demolition is also reduced.

During the lifting or lowering process of the dismantling platform 110, the fixing member is separated from the building, so that the dismantling platform 110 can be moved under the driving of the lifting member. The fixing member is connected to the wall of the building by bolts.

[0046] Referring to Figure 1 With Figure 2 In some specific embodiments of the utility model, the dismantling platform 110 is provided with a first track 111 along the circumference of the building, and the cutting assembly 200 is slidingly connected to the first track 111.

[0047] It is worth understanding that the cutting assembly 200 is slidingly connected to the first track 111, so that the cutting assembly 200 can move along the circumference of the building through the first track 111, and then the cutting assembly 200 can be moved to different positions of the building through the separate cutting assembly 200 to cut the beams or columns at various positions of the building, thereby reducing the manufacturing cost of the equipment.

[0048] In the embodiment, the first track 111 protrudes from the top surface of the dismantling platform 110, the cutting assembly 200 is clamped on both sides of the first track 111 from the first track 111, and moves relative to the first track 111 through a pulley.

[0049] In addition, both ends of the cutting assembly 200 along the length direction of the first track 111 are also provided with air outlets, and a fan is integrated on the cutting assembly 200 to blow the dust on the first track 111 through the air outlets in advance, thereby improving the smoothness of the movement of the cutting assembly 200. The cutting assembly 200 can also be positioned through the first track 111, so that the cutting assembly 200 can be aligned with the end of the beam or column, and the cutting size precision of the beam or column is higher.

[0050] Referring to Figure 3 In other specific embodiments of the utility model, the first track 111 can also be laid inside the building to cut the beams, columns and upper floors inside the building, further reducing manual work and improving the degree of automation.

[0051] With reference to Figure 1 With Figure 2 As shown in the drawings, in some embodiments of the present application, the building demolition device comprises two demolition assemblies 100 and two cutting assemblies 200 arranged oppositely, the two demolition assemblies 100 are respectively arranged at two first opposite sides of the building, and at least part of the demolition platform 110 is located at a second opposite side of the building; the first track 111 comprises a straight section and two arc sections respectively arranged at two ends of the straight section, the straight section is arranged at a first opposite side, and the two arc sections are respectively arranged at two second opposite sides; the two cutting assemblies 200 are respectively arranged at the two demolition platforms 110 and can slide along the first track 111 to move to the first opposite side or the second opposite side and cut the components; the lifting frame 300 is arranged at the second opposite side.

[0052] It is worth understanding that the two demolition platforms 110 are respectively arranged at opposite sides of the building to simultaneously perform construction and improve the demolition efficiency of the building.

[0053] In the present embodiment, the building is in the shape of a rectangular parallelepiped and comprises four sides, namely a first side, a second side, a third side and a fourth side in sequence, the first side is opposite to the third side, and the second side is opposite to the fourth side, one demolition assembly 100 is arranged at the first side, and the other demolition assembly 100 is arranged at the third side, and the lifting frame 300 is arranged at the second side. Among them, the straight section of the first track 111 is located at the first side or the third side, and the two arc sections are respectively located at the second side and the fourth side. The cutting assembly 200 on the demolition assembly 100 located at the first side can move on the first side through the first track 111 and can move to the second side and the fourth side to cut the beams on the second side or the fourth side, so that the building is more convenient to disassemble.

[0054] With reference to Figure 1 , Figure 2 With Figure 4As shown, in some embodiments of the utility model, the cutting assembly 200 includes a rotatable rotating table 210, a base 220 connected to the rotating table 210, a first rotating rod 230 rotatably connected to the base 220, a second rotating rod 240 rotatably connected to the first rotating rod 230, and a cutting member 250 rotatably connected to the second rotating rod 240, the cutting member 250 includes a first cutting state, a second cutting state, a first cutting position and a second cutting position; wherein the cutting member 250 is configured: in the first cutting state, the first rotating rod 230 is rotated to be distributed along the height direction of the building, and the second rotating rod 240 drives the cutting member 250 to cut the end of the beam; in the second cutting state, the first rotating rod 230 is rotated to be distributed along the horizontal direction, and the second rotating rod 240 drives the cutting member 250 to cut the end of the column; in the first cutting position, the rotating table 210 is located at the first opposite side to cut the beam and column of the first opposite side; in the second cutting position, the rotating table 210 is located at the second opposite side to cut the beam and column of the second opposite side.

[0055] It is worth understanding that through the rotation of the rotating table 210, the rotation of the first rotating rod 230 and the second rotating rod 240, the cutting member 250 has multiple positions to cut different positions of the beam or column, so that the same cutting member 250 can cut different components, which is more convenient to use and has lower use cost.

[0056] In this embodiment, the cutting member 250 further includes a third cutting state, wherein the cutting member 250 is located at the first side, and the wall of the first side has been removed, the first rotating rod 230 is rotated to be aligned with the root of the wall of the second side in the building along the horizontal direction, and the rotating table 210 is rotated so that the first rotating rod 230 cuts the root of the wall of the second side in the building, while the rotating table 210 moves along the first track 111 in the direction away from the second side, so that the cutting member 250 can move along the length direction of the root of the wall of the second side to cut the root of the wall of the second side, realizing the cutting of the wall. Wherein, when the cutting member 250 is aligned with the top of the wall along the horizontal direction, the cutting member 250 cuts the top of the wall.

[0057] In some embodiments of the utility model, the first rotating rod 230 can be telescopic along the length direction of the first rotating rod 230.

[0058] In this embodiment, when the first rotating rod 230 is in the second cutting state, the first rotating rod 230 can be telescopic along the length direction to move along the length direction of the first side, so that the cutting member 250 can cut the wall located at the first side, realizing the cutting of the wall of the first side.

[0059] In some embodiments of the utility model, the second rotating rod 240 can be telescopic along the length direction of the second rotating rod 240. The length of the second rotating rod 240 is changed, and the position of the cutting member 250 is conveniently adjusted.

[0060] As another embodiment, the non-load-bearing wall is mainly formed by stacking bricks, which is a structure stacked after the main frame of the building is completed. The structure has little reuse value and low structural strength, and can be removed by workers or by setting a wall removal tool, such as a wall removal machine with a drill bit, in the building to remove the wall.

[0061] Referring to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the utility model, the cutting assembly 200 further comprises a telescopic member 260, one end of the telescopic member 260 is rotatably connected to the first rotating rod 230, and the other end is rotatably connected to the second rotating rod 240. The telescopic member 260 is used to drive the second rotating rod 240 to rotate around the first rotating rod 230.

[0062] It is worth understanding that the second rotating rod 240 rotates around the first rotating rod 230 through the telescopic member 260. The telescopic rod can provide greater torque to the second rotating rod 240. The second rotating rod 240 adheres the cutting member 250 to the member through the torque, and then cuts the member, improving the reliability of the member cutting.

[0063] As another embodiment, the second rotating rod 240 can also be driven to rotate around the first rotating rod 230 by a motor. Specifically, the motor is fixed to the first rotating rod 230 and is in transmission connection with the second rotating rod 230. Among them, the rotation between the rotating table 210, the first rotating rod 230 and the base 220 is realized by the motor. Specifically, the rotating table 210 comprises a base and a rotating part. The base is slidably connected to the track 111. The motor is fixedly connected to the rotating part and is in transmission connection with the base, so that the rotating part can rotate relative to the base (wherein the motor rotates with the rotating part), realizing the rotation of the rotating table 210. The rotating motor of the base 220 is fixed to the rotating part and is in transmission connection with the base 220, so that the base 220 can rotate. The rotating motor of the first rotating rod 230 is fixed to the base 220 and is in transmission connection with the first rotating rod 230, so that the first rotating rod 230 can rotate.

[0064] Referring to Figure 4 , in some embodiments of the utility model, the axis of rotation of the first rotating rod 230 around the base 220 is the first rotation axis, the axis of rotation of the second rotating rod 240 around the first rotating rod 230 is the second rotation axis, and the first rotation axis is perpendicular to the second rotation axis.

[0065] It is worth understanding that the first rotation axis is perpendicular to the second rotation axis, so that when the second rotating rod 240 rotates around the first rotating rod 230, the rotation of the second rotating rod 240 and the vibration when the cutting member 250 cuts the member are not easy to interfere with the rotation connection between the first rotating rod 230 and the base 220, and the second rotating rod 240 can rotate more stably, thereby making the cutting of the cutting member 250 on the member more stable, and improving the cutting effect of the cutting member 250.

[0066] Referring to Figure 4 As shown in the utility model, in some specific embodiments of the utility model, the cutting member 250 includes a disc part and a sawtooth part arranged at the edge of the disc part, and the efficiency of the cutting member 250 in cutting the member is improved through the sawtooth part, so that the cutting effect of the cutting member 250 is better.

[0067] Referring to Figure 1 With Figure 2 As shown in the utility model, in some specific embodiments of the utility model, the lifting frame 300 includes a first guide 310 in the building height direction and a second guide connected to the member, and the second guide is used for guiding cooperation with the guide in the building height direction.

[0068] It should be noted that when the lifting frame 300 lifts the member in the building height direction, the member is easy to swing and collide with the building main body or the lifting frame 300, and the lifting and conveying of the member has a safety hazard, which is easy to cause safety accidents, and also easy to affect the integrity of the member, thereby affecting the reuse of the member.

[0069] It is worth understanding that the first guide 310 is arranged on the lifting frame 300, and the second guide is arranged on the member, and then the movement of the member is guided to avoid the possibility of swinging of the member during the conveying process in the building height direction, improve the transportation safety performance of the member, and at the same time be beneficial to the integrity of the member, and the member meets the use conditions of reuse.

[0070] In the embodiment, the first guide 310 is an electromagnet, and the second guide is an iron bar or other magnetically attracted objects that do not have magnetism by themselves. In the use process, when the lifting assembly 400 lifts the member, the electromagnet is not powered, when the lifting assembly 400 slowly moves the member to be basically aligned with the lifting frame 300, the electromagnet is powered, so that the second guide is attracted to the first guide 310, and at the same time, a magnetic force in the horizontal direction is applied to the member to overcome the swing force of the member in the horizontal direction, so that the member is attached to the lifting frame 300, and the movement of the member in the building height direction is more stable.

[0071] The utility model embodiment makes the detailed explanation in combination with the drawing, but the utility model is not limited to the above -mentioned embodiment, still can make various changes in the knowledge range that the person skilled in the art has possesses without departing from the utility model's tenet under the precondition that the utility model is not limited to the above -mentioned embodiment.
