Description

Technical Field

[0001] This invention relates to the field of concrete component reuse, and particularly to a grinding device for reinforced concrete components. Background Technology

[0002] Buildings need to be demolished after a certain number of years of use. Demolition is typically carried out using blasting or excavators equipped with drills. While blasting offers advantages such as speed and efficiency, it also has disadvantages including high noise and dust levels, safety hazards for personnel, damage to building components, and high costs for construction waste cleanup. Its operating costs and recyclable costs are relatively low. Excavator-based demolition, on the other hand, requires breaking down every single building component, resulting in low processing efficiency and making it difficult to retain intact components for reuse.

[0003] In related technologies, there are solutions that involve cutting components directly and reusing them. However, there are no exposed reinforcing bars on the cut surfaces of the components, making it difficult to connect them with other components to form a more reliable connection structure.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Generally, a reinforced concrete member has four main reinforcing bars distributed along its length. During the pouring and molding of the reinforced concrete member, some of the main reinforcing bars extend beyond the concrete portion to connect with other concrete components. After the reinforced concrete member is cut, the originally protruding portions of the main reinforcing bars are retained within the cut portion.

[0037] Reference Figures 1 to 5 As shown in the figure, this embodiment of the invention proposes a grinding device for reinforced concrete components. The grinding device grinds the remaining original protruding part of the main reinforcing bar, so that the remaining original protruding part of the main reinforcing bar is exposed outside the concrete part of the reinforced concrete component. This allows the reinforced concrete component to be reconnected to other reinforced concrete components through the main reinforcing bar in this part, realizing the reuse of the reinforced concrete component. The grinding device for reinforced concrete components includes: a grinding disc 100 and a drive assembly 200.

[0038] In this embodiment, the grinding disc 100 includes a grinding surface 110, clearance holes 120 disposed on the grinding surface 110, and a grinding assembly 130 disposed on the grinding surface 110. The clearance holes 120 are used to avoid the reinforcing bars at the mounting end, and the grinding assembly 130 is used to grind the end face of the mounting end. The grinding disc 100 is disc-shaped, the grinding surface 110 is the end face of the grinding disc 100, the clearance holes 120 are located basically at the center of the grinding disc 100, and at least communicate with the grinding surface 110 along the axial direction of the grinding disc 100. The clearance holes 120 may only communicate with the grinding surface 110, as long as the depth of the clearance holes 120 can accommodate the exposed length of the reinforcing bars of the reinforced concrete component. The clearance holes 120 may also communicate with the grinding surface 110 and the other end face opposite to the grinding surface 110 to accommodate the exposed reinforcing bars of the reinforced concrete component. The grinding assembly 130 consists of multiple cutting tools with a certain rigidity and hardness to fully grind the concrete portion of the reinforced concrete component and break it down, thereby exposing the reinforcing steel bars on the end face of the installation.

[0039] The drive assembly 200 is connected to the grinding disc 100 and is used to drive the grinding disc 100 to rotate. The drive assembly 200 is a torque motor, and the drive shaft of the torque motor is connected to the grinding disc 100. Because the length of the reinforcing bar that needs to be exposed on the mounting end face is limited, the axial length of the clearance hole 120 is limited. When the drive assembly 200 is connected to the center position of the grinding disc 100, the center position of the grinding disc 100 is provided with a transmission block that avoids the clearance hole 120 along its axial direction. The transmission block is connected to the drive shaft of the torque motor, so that the grinding disc 100 rotates.

[0040] It is worth understanding that during the grinding process of the grinding disc 100 grinding the end face of the installation end, the drive assembly 200 drives the grinding disc 100 to rotate and grind the installation end of the reinforced concrete component. The grinding device automatically retains the reinforcing bars on the end face of the installation end through the clearance hole 120, and only grinds the concrete part through the grinding assembly 130, so that the reinforcing bars of the reinforced concrete component are automatically exposed at the installation end of the reinforced concrete component. In the subsequent reuse process of the reinforced concrete component, it can be connected to the reinforcing bars of other components as a whole, and then cast to form a connection node. The connection node has higher connection strength, and the use of the reinforced concrete component is more convenient and reliable.

[0041] Reference Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the drive component 200 is configured to drive the grinding disc 100 to rotate eccentrically, define the projection along the axis perpendicular to the rotation as the projection surface, the projection of the eccentric rotation trajectory of the clearance hole 120 onto the projection surface has an overlapping area, and the projection of the reinforcing bar at the mounting end onto the projection surface is located within the overlapping area.

[0042] It is worth understanding that the grinding disc 100 rotates eccentrically so that the clearance hole 120 rotates eccentrically. Furthermore, the overlapping area of ​​the clearance hole 120 during eccentric rotation can be controlled by the amplitude of the eccentric rotation of the grinding disc 100. The size of the overlapping area is controllable, which can adapt to steel bars of different sizes. The grinding device for reinforced concrete components has a wider range of applications.

[0043] Specifically, the drive shaft of the drive assembly 200 is located within the clearance hole 120, and the axis of the drive shaft does not coincide with the axis of the clearance hole 120. During the rotation of the drive shaft, the eccentric rotation of the clearance hole 120 results in an overlapping area. The closer the axis of the drive shaft is to the center of the clearance hole 120, the larger the overlapping area; the closer the axis of the drive shaft is to the edge of the clearance hole 120, the smaller the overlapping area. Therefore, by changing the relative position of the drive shaft of the drive assembly 200 and the transmission block along the radial direction of the grinding disk 100, i.e., the relative position of the drive shaft and the axis of the clearance hole 120, the size of the overlapping area can be changed, thereby controlling the size of the exposed portion of the mounting end. In practical applications, the corresponding overlapping area size can be selected according to the size of the reinforcing bar on the end face of the mounting end, so that the reinforcing bar is precisely exposed after grinding.

[0044] Since the dimensions of the reinforcing bars are generally specified values ​​and are usually integers, the difference in dimensions between different specifications of reinforcing bars can be determined. Based on this difference in dimensions, the relative position of the drive shaft and the transmission block can be determined, and then a corresponding mounting structure can be set on the transmission block. For example, the transmission block can be set with bolt holes of different sizes, and different mounting positions can be distributed sequentially along the circumferential direction of the clearance hole 120, which is convenient for differentiation and connection of the drive shaft.

[0045] Reference Figure 4 and Figure 5 As shown, the grinding disc 100 has multiple sets of eccentric connecting holes 140, and the different sets of eccentric connecting holes 140 are distributed at intervals along the circumference of the grinding disc 100. Each set of eccentric connecting holes 140 is used to fixably connect to the drive shaft of the drive assembly 200 by means of bolts or other connecting parts. In this embodiment, the number of each set of eccentric connecting holes 140 is set to four.

[0046] Reference Figure 3 As shown, in some specific embodiments of the present invention, the inner circumferential surface of the clearance hole 120 is provided with rolling teeth.

[0047] It is understandable that during the eccentric rotation of the clearance hole 120, some concrete may enter the clearance hole 120. The compaction teeth on the inner circumference of the clearance hole 120 collide and squeeze the concrete remaining on the surface of the steel bar and the concrete inside the clearance hole 120, so that the concrete remaining on the surface of the steel bar can be further removed, thereby improving the exposure effect of the steel bar.

[0048] In this embodiment, the distance between the inner circumferential surface of the clearance hole 120 and the surface of the reinforcing bar is within a reasonable range. When concrete enters between the inner circumferential surface of the clearance hole 120 and the surface of the reinforcing bar, the rolling teeth can squeeze the concrete together with the reinforcing bar, and the concrete remaining on the surface of the reinforcing bar is also loosened and fell off due to the squeezing force, resulting in less concrete remaining on the surface of the reinforcing bar and a better exposure effect of the reinforcing bar.

[0049] Furthermore, during the eccentric rotation of the grinding disc 100, the grinding contact time at the location corresponding to the clearance hole 120 is shorter than that in other areas, resulting in insufficient grinding of the concrete near the reinforcing bar and making it easier for concrete residue to remain around the reinforcing bar. Increasing the grinding contact time of the concrete around the reinforcing bar by using the grinding teeth makes it less likely for concrete residue to remain around the reinforcing bar.

[0050] Furthermore, the radial section of the clearance hole 120 is perpendicular to the axial direction of the clearance hole 120. Along the direction from the grinding surface 110 to the other end face of the grinding disk 100, the radial section of the clearance hole 120 gradually abuts. In this embodiment, the radial section of the clearance hole 120 is circular, and its diameter gradually increases. The clearance hole 120 mainly grinds the circumferential surface of the reinforcing bar at the small end near the grinding surface 110. At the same time, the reinforcing bar is supported by the reinforced concrete component, and the reinforcing bar itself is not easily deformed. It can better remove the concrete from the surface of the reinforcing bar together with the grinding teeth. At the large end away from the grinding surface 110, the radial section of the clearance hole 120 increases, and the distance between the clearance hole 120 and the reinforcing bar increases. The clearance hole 120 is less likely to affect the end of the reinforcing bar away from the reinforced concrete component, thereby avoiding deformation of the reinforcing bar. In other embodiments, the clearance hole 120 is divided into multiple segments along its axial direction, each segment having a certain axial length. The axial length of each segment can be the same or different. The radial length of each segment can be a fixed value, but the radial lengths of different segments are different, and the radial lengths of different segments increase along the direction from the grinding surface 110 to the other end face of the grinding disk 100. Alternatively, the radial length of some segments is fixed, and the radial length of other segments increases along the direction from the grinding surface 110 to the other end face of the grinding disk 100.

[0051] Reference Figure 3 As shown, in some specific embodiments of the present invention, the grinding assembly 130 includes an edge grinding tooth 131 and a center grinding tooth 132, the center grinding tooth 132 surrounding the clearance hole 120, and the edge grinding tooth 131 surrounding the center grinding tooth 132.

[0052] It is understandable that the grinding assembly 130 grinds the concrete portion around the clearance hole 120 through the central grinding tooth 132, so that the concrete portion near the clearance hole 120 can be better ground, and the central grinding tooth 132 can better grind the portion surrounding the reinforcing bar in the mounting end of the reinforced concrete member; the edge grinding tooth 131 grinds the portion of the mounting end away from the reinforcing bar, so that the end face of the mounting end is fully ground.

[0053] Reference Figure 3 As shown, in some specific embodiments of the present invention, the central grinding tooth 132 protrudes from the grinding surface 110, and the central grinding tooth 132 includes a plurality of grinding sub-teeth distributed along an arc.

[0054] In this embodiment, the central grinding tooth 132 includes multiple tool sets, all of which are uniformly distributed around the axial direction of the clearance hole 120. Each tool set includes multiple tools arranged in a spiral pattern along the radial direction of the clearance hole 120. The spiral-shaped tools guide the ground concrete fragments out along the direction from the center of the clearance hole 120 to the outer edge of the grinding disk 100. Each tool is made of a high-strength wear-resistant material to ensure excellent wear resistance, impact resistance, and high-temperature stability during use, such as cemented carbide. The edge grinding tooth 131 uses a single-edged hob for crushing and grinding, enabling more efficient removal of concrete from reinforced concrete components. The material selection requirements for the edge grinding tooth 131 are basically the same as those for the central grinding tooth 132; cemented carbide can also be used.

[0055] Reference Figure 3 As shown, in some specific embodiments of the present invention, the grinding surface 110 has a mounting groove 111, and the edge grinding teeth 131 are mounted in the mounting groove 111. The edge grinding teeth 131 include a main body and a grinding part rotatably connected to the main body. At least a portion of the grinding part extends out of the groove of the mounting groove 111 located in the groove of the grinding surface 110.

[0056] It is worth understanding that the edge grinding teeth 131 can rotate. When the grinding disc 100 rotates, the edge grinding teeth 131 contact the installation end face of the reinforced concrete component. Driven by the contact pressure, the grinding part of the edge grinding teeth 131 rotates around its main body, causing the edge grinding teeth 131 to rotate and break the concrete part of the reinforced concrete component, thereby achieving efficient crushing of the reinforced concrete component.

[0057] In this embodiment, the grinding part is annular and the main body is disc-shaped. The grinding part and the main body are rotatably connected by a tapered roller bearing. The outer edge of the grinding part includes grinding teeth evenly distributed along its circumference. The grinding teeth can better grind the installation end face of the reinforced concrete component and improve the grinding effect.

[0058] Reference Figure 3 As shown, in some specific embodiments of the present invention, multiple edge grinding teeth 131 and multiple center grinding teeth 132 are provided. The multiple edge grinding teeth 131 are evenly distributed along the circumference of the clearance hole 120, and the multiple center grinding teeth 132 are evenly distributed along the circumference of the clearance hole 120.

[0059] It is worth understanding that the edge grinding teeth 131 and the center grinding teeth 132 are both distributed along the axial direction of the clearance hole 120, and the number of each is set to multiple, which makes the grinding efficiency of the grinding disc 100 higher, and can grind the installation end face of the reinforced concrete component more efficiently, thereby exposing the reinforcing steel on the installation end face.

[0060] In addition, to enable the edge grinding teeth 131 and the center grinding teeth 132 to operate at higher speeds, a cooling nozzle is provided on the grinding surface 110. The cooling nozzle is connected to the cooling tank and can be sprayed out by a water pump to draw water from the cooling tank, thereby removing the heat generated during the grinding of the edge grinding teeth 131 and the center grinding teeth 132 and improving their service life.

[0061] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, two grinding discs 100 are provided, and two drive components 200 are provided, with the two drive components 200 respectively connected to the two grinding discs 100 in a transmission manner; wherein, the two grinding discs 100 are configured to grind two steel bars that expose the mounting end face along the first diagonal direction respectively.

[0062] It should be noted that, generally speaking, reinforced concrete members have four main reinforcing bars distributed along their length. During the pouring and molding of the reinforced concrete member, some of the main reinforcing bars will extend beyond the concrete portion to connect with other concrete components. The shape formed by connecting the four main reinforcing bars in sequence is roughly rectangular, with the four main reinforcing bars located at the four ends of the rectangle.

[0063] The first diagonal direction is the direction of the line connecting the endpoints of two main reinforcing bars that are diagonally opposite each other.

[0064] It is understandable that by setting two grinding discs 100, the two grinding discs 100 grind the two main reinforcing bars at opposite corners, exposing these bars and improving the processing efficiency of the installation end face of the reinforced concrete component. The spacing between the two main reinforcing bars along the first diagonal direction is the largest, providing ample space to accommodate the grinding discs 100. This allows for a suitable increase in the radial dimension of the grinding discs 100, enabling the grinding of a larger area of ​​concrete and reducing dead corners.

[0065] Compared to a grinding device for reinforced concrete components with only one grinding disc 100, a grinding device for reinforced concrete components with two grinding discs 100 has higher grinding efficiency. Compared to a grinding device for reinforced concrete components with three or four grinding discs 100, a grinding device for reinforced concrete components with two grinding discs 100 has a larger grinding surface area 110, which greatly reduces the existence of dead corners and makes the end face of the reinforced concrete component more neatly ground.

[0066] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the grinding device for reinforced concrete components further includes: a spacing adjustment component 300, the grinding disc 100 and the corresponding driving component 200 are all disposed in the spacing adjustment component 300, and the spacing adjustment component 300 is used to adjust the distance between the two grinding discs 100.

[0067] It should be noted that the positional distribution of the four main reinforcing bars in different reinforced concrete components is not the same. In order to adapt to reinforced concrete components of different sizes, the relative position between the two grinding discs 100 is adjusted by the spacing adjustment component 300, so that the grinding device for reinforced concrete components can be adapted to reinforced concrete components of different sizes. The equipment has a lower operating cost, does not need to be customized for each size of reinforced concrete component, and the equipment cost is also lower.

[0068] In this embodiment, the spacing adjustment assembly 300 includes an adjustment fixing plate 310, two adjustment plates 320, two sliding rails 330, and two adjustment rails 340. The sliding rails 330 and adjustment rails 340 are both fixed to the adjustment fixing plate 310. The adjustment plates 320 slide through the two sliding rails 330 and are connected to the adjustment rails 340. The adjustment plates 320 can be fixed at any position or a preset position on the adjustment rails 340 to adjust the relative position of the two adjustment plates 320. Two drive assemblies 200 are respectively fixed to the two adjustment plates 320 and respectively support and drive the grinding discs 100. The spacing between the two grinding discs 100 is adjusted by the distance between the two adjustment plates 320. The adjustment rails 340 are screw-slider structures, with the slider fixedly connected to the adjustment plate 320 and the screw rotatably connected to the adjustment fixing plate 310.

[0069] It should also be noted that when the two grinding discs 100 rotate, the distance between them is fixed and a certain gap must be maintained to avoid mutual interference. The gap between the two grinding discs 100 will not be ground, resulting in some concrete residue that needs to be processed again. In this embodiment, because the grinding discs 100 rotate eccentrically, the movement trajectories of the grinding surfaces 110 of the two grinding discs 100 can partially overlap. However, during the rotation, the timing of the two grinding discs 100 passing through the overlapping part is not the same. One grinding disc 100 passes through the overlapping part first, and the other passes through the overlapping part later. This allows the two grinding discs 100 to grind the overlapping part simultaneously without interfering with each other, thereby increasing the grinding surface area 110 of the reinforced concrete component grinding device. The overlapping part of the two grinding discs 100 is the position between the two grinding discs 100. In terms of the installation end face of the reinforced concrete component, it is the center position between the two diagonally opposite main reinforcing bars (provided that the radial dimensions of the two grinding discs 100 are basically the same). This allows the two grinding discs 100 to grind the center position of the reinforced concrete component at the same time, resulting in less concrete residue on the installation end face, making the processing more convenient, and resulting in a flatter installation end face of the reinforced concrete component without the need for secondary processing to grind off excess concrete.

[0070] Reference Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, the grinding device for reinforced concrete components further includes: a rotating assembly 400, all grinding discs 100 and all driving assemblies 200 are connected to the rotating assembly 400, and the rotating assembly 400 is configured to: drive the grinding discs 100 and the driving assemblies 200 to move to the second diagonal direction, and respectively grind the two reinforcing bars that expose the mounting end faces along the second diagonal direction.

[0071] It is worth noting that by switching the position of the grinding disc 100 through the rotating component 400 without rotating the reinforced concrete component, the grinding device for reinforced concrete components can grind the reinforced concrete components more conveniently and with higher grinding efficiency.

[0072] In this embodiment, the rotating component 400 includes a turntable and a rotating motor. The turntable is connected to the rotating motor and rotates under the drive of the rotating motor. An adjustment track 340 is fixedly provided on the turntable to support the adjustment plate 320, and the adjustment plate 320 supports the drive component 200 and the grinding disc 100.

[0073] Reference Figure 1 and Figure 2As shown, in some specific embodiments of the present invention, the grinding device for reinforced concrete components further includes: a horizontal moving component 500, used to drive the rotating component 400 to move along the length direction of the reinforced concrete component.

[0074] The reinforced concrete components are placed horizontally. In this embodiment, the horizontal moving assembly 500 includes a support frame perpendicular to the ground, a horizontal moving component connected to the bottom of the support frame, a base supporting the horizontal moving component and the support frame, and an auxiliary sliding component connected to the base and passing through the support frame. The support frame is connected to the rotating assembly 400. The horizontal moving component is a screw-slider structure, with the slider connected to the support frame and the screw rotatably connected to the base.

[0075] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
