[0020] The present invention will be further described in detail below with reference to the drawings and embodiments. The same reference numerals are used for the same components. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of the specific component respectively.
[0021] Refer to Figures 1 to 4As shown in the figure, to achieve the above object, the present invention provides the following technical solution: A building steel bar demolition device, which includes a moving frame 1, a lifting member 2, a lifting seat 3, and a cutting assembly 4. The lifting seat 3 is slidably connected to the moving frame 1. The lifting member 2 is used to drive the lifting seat 3 to move up and down. The cutting assembly 4 is installed at the upper end of the lifting seat 3. An installation groove 31 is provided at the upper end of the lifting seat 3. A rotating seat 5, a guiding plate 6, and a driving member 7 are arranged in the installation groove 31. There are two groups of guiding plates 6, which are respectively arranged on both sides of the installation groove 31. Both guiding plates 6 are provided with guiding straight grooves 61 and guiding arc grooves 62. The guiding arc groove 62 is connected to the middle of the guiding straight groove 61. The rotating seat 5 is slidably connected to the guiding plate 6. The driving member 7 is used to drive the rotating seat 5 to slide along the guiding straight groove 61 into the guiding arc groove 62. When the driving member 7 drives the rotating seat 5 to move, the rotating seat 5 first moves along the guiding straight groove 61 and then flips 90° along the guiding arc groove 62.
[0022] In the design of the present invention, 1. The height of the cutting assembly 4 can be adjusted by the lifting member 2, so as to meet the requirements of cutting steel bars at different height positions.
[0023] 2. When performing a cutting operation on the upper end of the steel bar, a horizontal cutting operation is first performed. When vertical cutting is required, the orientation of the cutting assembly 4 can be changed by the driving member 7, so as to meet the cutting requirements of horizontal and vertical steel bars.
[0024] 3. Since square voids will be formed after the steel bars are arranged, during the process of adjusting the cutting orientation, the cutting part will first move upward and then flip. The advantage of this design is that it is not necessary to adjust the lifting member 2 twice, so that the cutting part can avoid the steel bar area during the flipping process and will not form an obstacle.
[0025] The present invention is further provided as follows: The driving member 7 includes a driving motor 71, a first connecting rod 72, and a second connecting rod 73. The driving motor 71 is installed on one guiding plate 6. The driving motor 71 is connected to the first end of the first connecting rod 72. The second end of the first connecting rod 72 is linked and connected to the first end of the second connecting rod 73. The second end of the second connecting rod 73 is linked and connected to the rotating seat 5.
[0026] Combined with Figure 2 and Figure 3 As shown, the first connecting rod 72 is directly connected to the driving motor 71. During the rotation of the first connecting rod 72, the rotating seat 5 can be driven to flip along the guiding plate 6 through the second connecting rod 73.
[0027] The present invention is further provided as follows: The rotating seat 5 includes a linkage part 51 with a T-shaped structure. The linkage part 51 includes a first guiding head 52, a second guiding head 53, and a linkage head 54. The second connecting rod 73 is connected to the linkage head 54. The first guiding head 52 is slidably connected within the straight guiding groove 61 or the arc guiding groove 62; The second guiding head 53 is always slidably connected within the straight guiding groove 61.
[0028] There are two sets of linkage parts 51, which are respectively slidably connected to the guiding plates 6 on both sides, and the two second guiding heads 53 are connected and arranged through a connecting rod. (The seat part of the rotating seat 5 is not drawn in the figure) As Figure 3 shown, the flipping steps include: 1. When the first connecting rod 72 rotates, the linkage part 51 will first move linearly along the straight guiding groove 61. At this time, the rotating seat 5 will move upward first, causing the cutting assembly 4 to be misaligned with the corresponding steel bar; 2. When the first connecting rod 72 continues to rotate, at this time the first guiding head 52 is located within the arc guiding groove 62, the second guiding head 53 abuts against one end of the straight guiding groove 61, and the linkage part 51 rotates around the second guiding head 53 and makes a flipping movement along the arc guiding groove 62, with a flipping angle of 90°, which can change the cutting direction from horizontal to vertical.
[0029] The present invention is further configured as: The cutting assembly 4 includes a cutting member 41, a cutting seat 42, and a driving cylinder 43. The cutting seat 42 is slidably connected to the rotating seat 5, the cutting member 41 is fixedly installed on the cutting seat 42, and the driving cylinder 43 is used to drive the cutting seat 42 to move. This structure is a prior art, and the driving cylinder 43 or other motor screw structures are used to drive the cutting seat 42 to approach or move away from the steel bar to meet the cutting requirements.
[0030] The present invention is further configured as: The lifting member 2 includes a lifting motor 21, a lifting rod 22, a guiding rod 23, and a transmission gear set 24. The lifting motor 21 is linked with the lifting rod 22 through the transmission gear set 24. The lifting seat 3 is connected to the upper end of the lifting rod 22. A guiding hole for the guiding rod 23 to pass through is provided on the moving frame 1. The guiding rod 23 is arranged at the lower end of the lifting seat 3 and symmetrically arranged at both ends of the lifting rod 22.
[0031] As Figure 1 and Figure 2 shown, the transmission gear set 24 includes two bevel gears that can mesh with each other. When the driving motor 71 drives one bevel gear to rotate, the other bevel gear that meshes with it can be driven to rotate, thereby driving the lifting rod 22 to rotate.
[0032] The lifting rod 22 is designed using prior art and is composed of a threaded rod body, a rod body with a threaded groove, and a bearing. When the threaded rod body rotates with the bevel gear, the other rod body can move up and down.
[0033] And under the action of the guiding rod 23 and the guiding hole, the stable lifting of the lifting seat 3 is ensured.
[0034] The present invention is further configured as follows: a balancing component 8 is provided on the moving frame 1 , and the balancing component 8 is provided in linkage with the lifting motor 21 .
[0035] The present invention is further configured as follows: the mobile frame 1 includes a base 11 located at the lower end, a sliding groove 12 is arranged in the base 11, an expansion plate 13 is slidingly connected in the sliding groove 12, and the expansion plate 13 is linked to the balancing component 8.

[0037] The design of the balancing assembly 8 can increase the size of the base 11 when the lifting seat 3 rises. The larger the area of the base 11, the more stable the center of gravity. When the lifting seat 3 falls back, the size of the base 11 is reduced, thereby facilitating storage of the equipment.
[0038] The transmission gear set 24, while retaining the two original bevel gears, further includes: Figure 4 The driving gear shown can mesh with the expansion gear 82, and the driving gear is also installed on the lifting motor 21. When the lifting motor 21 is started, the expansion gear 82 can be driven to rotate through the driving gear, so that the expansion rod 81 can rotate accordingly.
[0039] The structure of the expansion rod 81 is consistent with that of the lifting rod 22, and the existing technology is adopted to achieve telescopic adjustment during the rotation process.
[0040] In summary, the transmission gear set 24 includes but is not limited to the above-mentioned gears. In order to meet the spatial arrangement requirements, the deceleration requirements, and the extension ratio requirements, multiple gears can be additionally provided.
[0041] The present invention is further configured as follows: the expansion plate 13 is provided with a plurality of support grooves 14 along its length direction; a support rod 15 is hingedly connected to the mobile frame 1; and a support foot 16 is telescopically provided at the lower end of the support rod 15 .
[0042] With the design of this structure, when the expansion plate 13 is extended, the support rod 15 can be moved, and then the support foot 16 can be pulled out so that the support foot 16 is inserted into the support groove 14, thereby enhancing the stability of both.
[0043] The support foot 16 and the support rod 15 are in sliding cooperation, and there is a rubber member between the two to increase the friction force, thereby achieving resistive sliding.
[0044] A torsion spring is provided between the support rod 15 and the moving frame 1. With their cooperation, the support feet 16 can be engaged into the support grooves 14.
[0045] Further preferably, as Figure 1 and Figure 2 shown, in order to facilitate the flipping of the rotating seat 5, the lifting seat 3 is arranged in a stepped structure.
[0046] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
