Description

Technical Field

[0001] This invention relates to the field of construction machinery, specifically to a protective demolition equipment and method for decorative flooring blocks. Background Technology

[0002] In recent years, with the deepening of urban renewal, there has been an increasing number of projects involving the protection, renovation, relocation, and jacking of historical buildings. In these projects, due to the need for structural replacement, it is often necessary to protectively remove decorative blocks such as floor tiles, ceramic tiles, and mosaics from the ground floor. After removal, it is required to protect and preserve these decorative blocks. Since the original floor decorative blocks were spliced ​​and bonded with mortar materials, protective removal is difficult and can easily cause damage.

[0003] There are currently two types of conventional protective demolition methods. One type involves removing the reinforced concrete slab from the ground. This is often done by cutting the slab into large pieces and preserving them in bulk, resulting in a large area of ​​damage. This is especially problematic when preserving partially patterned floor tiles or mosaics intact, as this presents numerous challenges and makes preservation and restoration difficult. The other type involves laying decorative blocks directly on rammed earth or brickwork and then removing them through manual excavation, digging, and dismantling. This method requires a large amount of manpower, is inefficient, and time-consuming. It is also difficult to preserve the blocks intact during on-site dismantling, and most of the blocks end up incomplete when restored and reused later. Summary of the Invention

[0004] In view of the problems of low efficiency, large size, easy damage during dismantling, and difficulty in repair and utilization of existing protective removal work for floor decorative blocks (tiles, mosaics), this invention provides a protective removal construction equipment and method for floor decorative blocks to solve the problems of protective removal and subsequent repair and utilization of floor decorative blocks. It is applicable to various base layers and floor tile, mosaic materials.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A protective removal construction equipment for floor decorative blocks includes a three-axis frame, a power system, a control handle, and cutting blades. The three-axis frame includes one main shaft and two auxiliary shafts. A spiral drill rod is embedded in the auxiliary shaft. The power system is installed on the main shaft. The control handle is connected to the power system. The power system is driven by the spiral drill rod and the cutting blades.

[0007] As a preferred technical solution, the power system includes a motor, a secondary shaft drive wheel, and a main shaft drive wheel. The motor controls the rotation direction and power of the motor rotor through a control handle. The motor rotor shaft is divided into inner and outer parts, and the two parts are nested and connected to the secondary shaft drive wheel and the main shaft drive wheel respectively. The nesting method is unidirectional transmission. The main shaft drive wheel is connected to the cutting blade, and the secondary shaft drive wheel is connected to the auger drill rod.

[0008] As a preferred technical solution, the cutting insert includes a cutting drive wheel, a central shaft, a sleeve, a key, a cover plate, and the insert. The main shaft drive wheel is connected to the cutting drive wheel via a conveyor belt. The top end of the central shaft is coaxially and fixedly connected to the cutting drive wheel. The bottom end of the central shaft is fixed to the insert. The sleeve is fitted onto the central shaft, and the bottom end of the sleeve is fixed to the cover plate. The cover plate covers the insert. The sleeve and the central shaft are connected by a key.

[0009] As a preferred technical solution, the pin passes through the cover plate, and the pin is provided with a water injection hole to make the pin tubular.

[0010] As a preferred technical solution, a method for using protective removal equipment for floor decorative blocks includes the following steps:

[0011] Step 1: Partially remove the floor decorative blocks;

[0012] Step 2: Adjust the equipment placement posture;

[0013] Step 3: Begin cutting;

[0014] Step 4: Sorting materials and moving the machine position.

[0015] As a preferred technical solution, in step two, adjusting the equipment placement posture includes: placing the equipment so that one main shaft and two auxiliary shafts are both located in the exposed adhesive layer or base layer area; controlling the rotation direction of the motor by controlling the control handle to make the spiral drill rods embedded in the two auxiliary shafts rotate and drill into the adhesive layer or base layer structural board; ensuring that the frame is firmly fixed; and adjusting the height of the spiral foot at the bottom of the main shaft so that the cutting blade is consistent with the bottom surface of the decorative block and the thickness of the adhesive layer in vertical height.

[0016] As a preferred technical solution, in step three, the cutting step includes: controlling the rotation direction of the motor by controlling the control handle to make the cutting blade start to rotate, and controlling the power of the motor by controlling the control handle. The horizontal rotation of the direction handle makes the cutting blade start to rotate in a plane around the spindle. The cutting blade approaches the adhesive layer and begins to cut horizontally. During the cutting process, water is injected through the water injection hole on the key.

[0017] As a preferred technical solution, step four includes: the cut decorative blocks fall onto the cover plate, forming a new working surface after sorting; the machine position is moved to repeat steps two and three, and the dismantling and construction of the entire area is completed by advancing the process in sections and blocks.

[0018] Compared with the prior art, the protective removal equipment and method for floor decorative blocks of the present invention have the following advantages:

[0019] (1) It solves the problems of difficult preservation, low efficiency and easy damage in the protective removal and construction of floor decorative blocks, and realizes low-carbon, green and efficient construction.

[0020] (2) The dismantling process directly cuts away the original mortar bonding layer, reducing secondary damage to decorative blocks such as bricks and mosaics during the dismantling process. After dismantling, the blocks are directly used as raw materials, improving the degree of repair and utilization, and playing a positive role in the protection and preservation of the characteristic parts of historical buildings.

[0030] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0031] like Figure 1 As shown, a protective removal construction equipment for floor decorative blocks includes a three-axis frame 1, a power system 2, a control handle 3, and a cutting blade 4. The three-axis frame 1 includes a main shaft 11 and two auxiliary shafts 12. A spiral drill rod 13 is embedded in the auxiliary shaft 12. The power system 2 is installed on the main shaft 11. The control handle 3 is connected to the power system 2. The power system 2 is driven by the spiral drill rod 13 and the cutting blade 4.

[0032] like Figure 2 and Figure 3 As shown, the power system 2 includes a motor 21, a main shaft drive wheel 23, and two secondary shaft drive wheels 22, as follows: Figure 4 As shown, the motor 21 controls the direction and power of its rotor rotation via the control handle 3, similar to the control handle 3 in an electric vehicle. The rotor shaft of the motor 21 is divided into inner and outer parts, each nested with the main shaft drive wheel 23 and two secondary shaft drive wheels 22, respectively. The nesting method is unidirectional transmission. The main shaft drive wheel 23 is connected to the cutting blade 4, as shown in the diagram. Figure 6 As shown, the secondary shaft drive wheel 22 corresponds one-to-one with the auger drill rod 13 and the two are connected by a one-way drive bearing. When the motor 21 rotates forward, the main shaft drive wheel 23 rotates, driving the cutting blade 4 to work, while the two secondary shaft drive wheels 22 do not rotate; when the motor 21 rotates in reverse, the two secondary shaft drive wheels 22 rotate, driving the two auger drill rods 13 to rotate, while the main shaft drive wheel 23 does not rotate.

[0033] like Figure 5 As shown, the cutting insert 4 includes a cutting drive wheel 41, a central shaft 42, a sleeve 43, a key 44, a cover plate 45, and an insert 46. The spindle drive wheel 23 is connected to the cutting drive wheel 41 via a conveyor belt. The top end of the central shaft 42 is coaxially and fixedly connected to the cutting drive wheel 41, and the bottom end of the central shaft 42 is fixed to the insert 46. The sleeve 43 is fitted onto the central shaft 42, and the bottom end of the sleeve 43 is fixed to the cover plate 45. The cover plate 45 covers the insert 46, and the sleeve 43 and the central shaft 42 are connected by the key 44. The key 44 is used to ensure that when the spindle drive wheel 23 rotates horizontally, the cover plate 45 and the insert 46 are aligned with the cutting direction.

[0034] The key 44 passes through the cover plate 45, and the key 44 is provided with a water injection hole so that the key 44 is tubular, so that water can be injected during the cutting process to reduce the cutting temperature.

[0035] A method for using protective removal equipment for floor decorative blocks includes the following steps:

[0036] Step 1: Partially remove the floor decorative blocks;

[0037] Specifically, select a corner of the room or an area where the decorative blocks are severely damaged, and manually remove the surface layer of the decorative blocks to expose the adhesive layer or the base structural board.

[0038] Step two, as Figure 7 As shown, adjust the equipment placement posture;

[0039] Specifically, the equipment is placed so that one main shaft 11 and two auxiliary shafts 12 are located in the exposed adhesive layer or base layer area. The rotation direction of the motor 21 is controlled by the control handle 3, so that the spiral drill rods 13 embedded in the two auxiliary shafts 12 rotate and drill into the adhesive layer or base layer structure board. Ensure that the frame is firmly fixed. Adjust the height of the spiral foot at the bottom of the main shaft 11 so that the cutting blade 4 is aligned with the bottom surface of the decorative block and the thickness of the adhesive layer in vertical height.

[0040] Step 3, as Figure 8 As shown, begin cutting;

[0041] Specifically, the direction of rotation of motor 21 is controlled by control handle 3, so that cutting blade 4 starts to rotate. The power of motor 21 is controlled by control handle 3. The direction handle is rotated horizontally so that cutting blade 4 starts to rotate in a plane around spindle 11. Cutting blade 4 approaches the adhesive layer and starts horizontal cutting. During the cutting process, water is injected through the water injection hole on key 44.

[0042] Step 4: Sorting materials and moving the machine position.

[0043] Specifically, the cut decorative blocks fall onto the cover plate 45, forming a new working surface after sorting. The machine position is moved to repeat steps two and three, and the dismantling and construction of the entire area is completed by advancing the process in sections and blocks.

[0044] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-creative modifications to this embodiment as needed after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
