Description

Technical Field

[0001] This invention relates to the field of construction waste treatment, specifically a construction waste treatment facility for construction projects. Background Technology

[0002] Construction waste refers to building materials generated during construction projects due to human or natural causes, including slag, excavated soil, bamboo and wood, silt, and other discarded materials. These materials offer no benefit to the building itself in the later stages, but they are necessary or generated during the construction process. Therefore, after construction is completed, construction waste needs to be properly disposed of to ensure the project achieves its intended goals. Because it is a holistic process, careful consideration of each stage is crucial. Formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the weight of the formwork itself and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate construction progress, and reduce project costs. After its service life, formwork becomes construction waste. Some formwork, due to its structural integrity and durability, can be recycled and reused after cleaning, reducing construction costs. However, as one of the components that directly contact concrete or walls and floors during construction, the surface of formwork often adheres to varying degrees of concrete residue, mud, and dust. Furthermore, the number of formwork generated in construction projects is often enormous. Using traditional cleaning and recycling methods to handle the residue adhering to the formwork surface often presents the following difficulties: Because construction projects use a large number of templates of different specifications, and the residue on the template surface is unevenly distributed, traditional recycling and processing institutions have difficulty adapting to the size changes of templates of different specifications, making it difficult to peel off and decompose the residue adhering to the template surface layer by layer, to accelerate the removal of residue by multi-angle and multi-directional tapping, and to carry out regional distributed grinding of the upper surface of the template. This increases the probability that the overall cleaning and grinding will not be smooth due to the large volume of residue adhering in a single area, thereby reducing the efficiency of template recycling and cleaning and the cleanliness after cleaning. Summary of the Invention

[0003] This invention provides a construction waste treatment mechanism for building engineering, which solves the technical problem that traditional recycling and treatment mechanisms are difficult to adapt to the size changes of templates of different specifications during the process of recycling and reuse of building templates, and that the residues adhering to the template surface are peeled off and decomposed layer by layer, which reduces the efficiency of template recycling and cleaning and the cleanliness after cleaning.

[0014] The beneficial effects of this invention are: (1) The construction waste treatment mechanism for construction engineering described in this invention, through a telescopic cleaning rod with multiple workstations, can adapt to the width changes of templates of different specifications. The elastically set friction plates can conform to the surface of the template through their adaptive deformation, and grind and clean the residue on the upper surface of the template. The protruding teeth set on the friction plates can improve the cleaning and scraping effect of the residue. Through the cleaning ring with multiple workstations, the upper surface of the template can be regionally distributed to grind, so that the grinding and cleaning areas of adjacent areas do not affect each other, thereby avoiding the uneven grinding caused by the large volume of residue adhering in a single area. Through the tilting and swinging of the cleaning rod, the cleaning and grinding operation of the friction plates can be carried out at the front, middle and rear.

[0015] (2) The construction waste treatment mechanism for construction engineering described in this invention can peel off and decompose the residue adhering to the upper surface of the template layer by layer by using the progressive baffles and linear cutting action of the inclined wire cutting cable. Through the arc surface structure of the wire cutting block itself and the vibration of the magnetic sand inside the wire cutting block, the ability of the wire cutting block to flip over the residue can be improved, so that the wire cutting block can perform multi-directional knocking and grinding operations from the front, back, left, right and top of the residue, thereby increasing the rate of residue shedding. Through the serrated wire cutting groove and the pin inserted in the groove, large-volume residue can be ground and decomposed multiple times. And through the hollow setting, the heat dissipation effect of the wire cutting block itself is improved, thereby increasing the continuous use time. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] An embodiment of the present invention is described below. Figures 1 to 3 A construction waste treatment mechanism for construction projects includes a base frame 1, conveying rollers 2, and scrapers 3. Several conveying rollers 2 are detachably installed in the middle of the base frame 1, and scrapers 3 are detachably installed at the upper end of the base frame 1. The base frame 1 has an "H" shaped structure. The conveying rollers 2 are horizontally installed on the front and rear sides of the base frame 1. Scrapers 3 are symmetrically installed on the left and right sides of the upper end of the base frame 1. The scrapers 3 are perpendicular to the axis of the conveying rollers 2, and a shovel frame 4 is detachably installed in the middle of the scraper 3.

[0020] As one embodiment of the present invention, such as Figure 3 , Figure 4 and Figure 11As shown, two sets of crossbars 40 are symmetrically installed at the front and rear ends of the scraper 3. A cross plate 42 is installed at the end of each set of crossbars 40. A wire cutting cable 5 is movably installed on the cross plate 42. A vertical shaft 6 is installed in the middle of the scraper 3 through a bearing. A synchronous pulley 61 is fixedly installed at the lower part of the vertical shaft 6. Multiple synchronous pulleys 61 are connected and driven by a synchronous belt 62. Square grooves 11 are symmetrically opened on the left and right sides of the "H"-shaped middle of the base frame 1. A slider 12 is slidably installed in each square groove 11. Pull ropes 41 are movably installed at both ends of the shovel frame 4. The pull ropes 41 at both ends are respectively connected to the sliders 12 on the left and right sides of the base frame 1. An idler wheel 13 is installed at the lower part of the slider 12 by rotational engagement. The idler wheel 13 is at the same height as the synchronous pulley 61. The middle part of the synchronous belt 62 slides against the side wall of the idler wheel 13. A two-way cylinder 14 is fixedly installed in the middle of the base frame 1. The two telescopic ends of the two-way cylinder 14 are respectively connected to the sliders 12 on both sides.

[0021] In the specific operation, the wall template 00 to be recycled and cleaned is first placed on the base frame 1 by manual labor or existing hoisting equipment. Then, the conveyor roller 2 is started to operate, and the operation of the conveyor roller 2 realizes the forward movement of the template 00, so that the template 00 enters the working area. During the conveying of the template 00, the bidirectional cylinder 14 is started, and the telescopic end of the bidirectional cylinder 14 moves back and forth. Then, the telescopic end of the bidirectional cylinder 14 drives the two sliders 12 to move in opposite directions in a straight line within the square groove 11. The sliders 12 drive the idler wheel 13 to move synchronously. During the reciprocating movement of the idler wheel 13, the middle part of the synchronous belt 62 is intermittently pulled by the abutment, so that the synchronous belt 62 generates a reciprocating rotation within a certain angle. Then, through the meshing transmission between the synchronous wheel 61 and the synchronous belt 62, the vertical shaft 6 reciprocates within a predetermined angle.

[0022] As one embodiment of the present invention, such as Figures 11 to 13As shown, a fixed plate 7 is evenly installed in the middle of the shovel frame 4. An annular groove 71 is formed in the middle of the annular surface of the fixed plate 7. A rotating frame 72 is slidably installed in the annular groove 71. A cleaning ring 73 is detachably installed at the lower part of the rotating frame 72. A rotating rod 721 with the same diameter as the fixed plate 7 is located in the middle of the rotating frame 72. Both ends of the rotating rod 721 are slidably fitted into the annular groove 71, and both ends of the rotating rod 721 are connected to the fixed plate 7 by compression springs 722. An approach rod 723 is slidably fitted into the middle of the rotating rod 721. A locking bolt 724 is installed at the upper end of the approach rod 723, and the end of the locking bolt 724 abuts against the side wall of the rotating rod 721. The cleaning ring 73 is detachably installed in… The lower part of the approach rod 723 and the upper part of the approach rod 723 are fixedly installed with a sector disk 725. The upper end of the fixed disk 7 is installed with a limit shaft 76 through a bearing. The upper parts of multiple fixed disks 7 are jointly installed with a pull rod 77 through a sliding fit. The pull rod 77 is located between the limit shaft 76 and the sector disk 725, and the limit shaft 76 abuts against the side wall of the pull rod 77 through a rolling fit. The arc-shaped side wall of the sector disk 725 and the side wall of the pull rod 77 on the same side as the arc-shaped side wall are symmetrically provided with meshing teeth. The left and right ends of the shovel frame 4 are both installed with steering wheels 43 through a rotating fit. The middle part of the pull rope 41 abuts against the side wall of the steering wheel 43, and the ends of the two pull ropes 41 are respectively connected to the two ends of the pull rod 77.

[0023] In actual operation, at the initial working position, the operator adjusts the working position of the approach rod 723 on the indexing rod 721, and after the adjustment, tightens the locking bolt 724 to fix the relative position of the two. Subsequently, during the reciprocating linear movement of the slider 12, the pull rod 77 reciprocates linearly within the shovel frame 4 through the connection of the pull rope 41. This, in turn, causes the sector disk 725 to reciprocate and deflect through the meshing transmission between the pull rod 77 and the sector disk 725. When the movement distance of the pull rod 77 exceeds the meshing range with the sector disk 725, the sector disk 725 stops rotating and the pull rod 77 stops moving. Slippage occurs between the rods 77 until the pull rod 77 moves in the opposite direction to reset. During the rotation of the sector disk 725, the transmission action of the approach rod 723 causes the indexing rod 721 to reciprocate synchronously within the annular groove 71. Through the elastic extension and contraction of the compression spring 722, the rotation of the indexing rod 721 is provided with a continuous restoring force, so that the deflection angle of the sector disk 725 is within the preset range when it is in meshing contact or slipping contact with the pull rod 77. Furthermore, during the rotation of the approach rod 723 and the indexing rod 721, the cleaning ring 73 set below is driven to rotate synchronously.

[0024] As one embodiment of the present invention, such as Figures 11 to 13As shown, the cleaning ring 73 is a downward-opening semi-circular ring structure. A cleaning rod 74 is detachably installed at the open end of the cleaning ring 73. The cleaning rod 74 is a telescopic multi-segment structure. The lower part of the cleaning rod 74 has an inwardly recessed notch, in which a friction plate 741 is snapped and installed. The friction plate 741 is an elastic structure, parallel to the central axis of the cleaning rod 74, and the lower end of the friction plate 741 protrudes from the lower notch of the cleaning rod 74. The two sidewalls of the friction plate 741 The cleaning ring 73 is uniformly provided with protruding teeth 742, which are spaced apart and have a tapered structure with the tip pointing downwards. The cleaning ring 73 has a cleaning rod 75 installed at the open end by means of rotational engagement. The cleaning rod 75 is located on both sides of the cleaning rod 74. The angle between the axis of the cleaning rod 75 and the axis of the cleaning rod 74 is an acute angle. A torsion spring connects the cleaning rod 75 and the cleaning ring 73. The lower part of the cleaning rod 75 is uniformly provided with bristles, and the lower end of the bristles is at the same height as the lower end of the friction plate 741.

[0025] In specific operation, when adjusting the relative position between the approach rod 723 and the indexing rod 721, the telescopic length between the multiple cleaning rods 74 is simultaneously adjusted so that the multiple cleaning rods 74 are aligned end to end, thereby adapting to the width variations of templates 00 of different specifications. When the template 00 is conveyed by the conveying roller 2 to the position below the cleaning ring 73, the friction plate 741 first adheres to the upper surface of the template 00 and undergoes adaptive deformation and bending. Subsequently, as the cleaning ring 73 rotates, the cleaning rods 74 rotate circumferentially, driving the friction plate 741 below it to rotate synchronously. The friction plate 741 polishes and cleans the upper surface of the template 00. The protruding teeth 742 set on the friction plate 741 can improve the cleaning and scraping effect of the residue. Through the multi-station cleaning ring 741, the cleaning rods 744 rotate circumferentially. 3. The upper surface of the template 00 can be regionally distributed for grinding, so that the grinding and cleaning areas of adjacent areas do not affect each other. This avoids uneven grinding caused by excessive residue adhesion in a single area. Secondly, during the rotation of the cleaning ring 73, the cleaning rod 75 is driven to rotate synchronously in the circumferential direction. Through the torsion force of the torsion spring, the cleaning rod 75 swings during the circumferential rotation of the cleaning rod 75 and the contact between the lower bristles and the residue. Through the rotation and swing of the cleaning rod 75, the upper surface of the template 00 can be swept and cleaned multiple times before, during and after the grinding and cleaning operation of the friction plate 741. This keeps the removed residue away from the grinding operation area, thereby reducing the workload of the friction plate 741 during the scraping operation and improving the cleaning efficiency and the cleanliness after cleaning.

[0026] As one embodiment of the present invention, such as Figures 5 to 10As shown, the horizontal plate 42 has symmetrically arranged strip grooves 431 at both ends. Tensioning blocks 432 are slidably installed in the strip grooves 431. Tensioning wheels 433 are detachably installed on the upper part of the tensioning blocks 432. The wire cutting cable 5 is sleeved on the tensioning wheel 433. A deflecting block 51 is fixedly installed in the middle of the wire cutting cable 5. A deflecting rod 63 is fixedly installed on the upper part of the vertical shaft 6. The front part of the deflecting rod 63 has a "U" shaped structure. A roller is installed on the lower part of the deflecting block 51 through a rotatable engagement. The roller is located in the "U" shape at the front of the deflecting rod 63. Wire cutting blocks 52 are evenly installed in the middle of the wire cutting cable 5. The wire cutting block 52 has a cylindrical structure and both ends of the wire cutting block 52 are provided with tapered heads with gradually decreasing diameters. The lower middle part of the wire cutting block 52 is uniformly provided with wire cutting grooves 521. The wire cutting grooves 521 are serrated with an oblique downward direction. Pins 522 are uniformly arranged at the bottom of the wire cutting grooves 521. The ends of the pins 522 are exposed outside the wire cutting grooves 521 and the pins 522 are perpendicular to the central axis of the wire cutting block 52. The inner side of the wire cutting block 52 is a hollow structure. The hollow groove of the wire cutting block 52 is filled with magnetic sand 523. A permanent magnet 21 is installed in the middle of the conveying roller 2 and the permanent magnet 21 is attracted to the magnetic sand 523.

[0027] In practice, at the initial position, the tensioning block 432 is moved within the strip groove 431 by the operator. The tensioning block 432 drives the tensioning wheel 433 to move synchronously. While the tensioning wheel 433 tightens the wire cutting cable 5, it also causes the wire cutting cables 5 on both sides of the base frame 1 to expand and contract within a certain angle. This causes the wire cutting cable 5 located in the middle of the base frame 1 to deflect within a certain angle. Subsequently, during the reciprocating deflection of the vertical shaft 6, it drives the upper actuating rod 63 to reciprocate within a certain angle, thereby causing the front "U"-shaped knot to... The limiting action between the mechanism and the lower roller of the actuating block 51 causes the actuating block 51 to reciprocate linearly in the horizontal direction. The actuating block 51 causes the parallel wire cutting cables 5 on both sides of the base frame 1 to reciprocate linearly, thereby causing the wire cutting cables 5 to reciprocate within a certain angle. Through the blocking and linear cutting action of the wire cutting cables 5, the residue adhering to the upper surface of the template 00 is peeled and decomposed. The inclination of the wire cutting cables 5 themselves allows for progressive cutting of the residue on the upper surface of the template 00. The evenly distributed wire cutting blocks 52, with their tapered inclined surfaces at both ends, when they touch the general... When residue accumulates, the wire cutting block 52 smoothly slides to the side of the residue and is worn away and decomposed by the serrated wire cutting groove 521 set in its lower part. The hollow design improves the heat dissipation of the wire cutting block 52 itself. The pins 522 set in the wire cutting groove 521 can enhance the scraping effect on the residue. The wire cutting cable 5 reciprocates, driving the wire cutting block 52 to move back and forth, allowing the wire cutting block 52 to reciprocate through both ends of the residue, thereby reciprocatingly impacting and wearing away the residue. During the reciprocating contact and collision between the wire cutting block 52 and the residue, the wire cutting block 52 is set with... The magnetic sand 523 inside the hollow groove of the wire cutting block 52 can reciprocate under this action, thereby causing the wire cutting block 52 to generate vertical polarization within a certain range. Combined with the arc-shaped outer wall structure of the wire cutting block 52 itself, it can enhance the ability of the wire cutting block 52 to flip over the residue, allowing the wire cutting block 52 to perform multi-directional knocking and grinding operations from the front, back, left, right and top of the residue, further increasing the residue shedding rate. Secondly, through the adsorption effect between the permanent magnet 21 and the magnetic sand 523, the pressure when the wire cutting block 52 contacts the residue on the upper surface of the template 00 can be increased, thereby improving the impact and cutting effect.

[0028] During work: Step 1: First, place the wall template 00 to be recycled and cleaned onto the base frame 1 manually or using existing hoisting equipment. Then, start the conveyor roller 2 to move the template 00 forward and into the work area. During the conveying of the template 00, start the bidirectional cylinder 14 to reciprocate. The extension end of the bidirectional cylinder 14 then drives two sliders 12 to reciprocate linearly in opposite directions within the square groove 11. The sliders 12 drive the idler wheel 13 to move synchronously. During the reciprocating movement of the idler wheel 13, it intermittently pulls the middle of the synchronous belt 62 through the abutment action, causing the synchronous belt 62 to reciprocate within a certain angle. Then, through the meshing transmission between the synchronous pulley 61 and the synchronous belt 62, the vertical shaft 6 reciprocates within a predetermined angle.

[0029] Step 2: At the initial work station, the tensioning block 432 is pushed by the staff to move in the strip groove 431. The tensioning block 432 drives the tensioning wheel 433 to move synchronously. While the tensioning wheel 433 tightens the wire cutting cable 5, the wire cutting cables 5 on both sides of the base frame 1 expand and contract within a certain angle, thereby causing the wire cutting cable 5 located in the middle of the base frame 1 to deflect within a certain angle. The operator adjusts the working position of the approach rod 723 on the indexing rod 721, and after the adjustment is completed, tightens the locking bolt 724 to fix the relative position of the two. Then, during the reciprocating linear movement of the slider 12, the pull rod 77 reciprocates linearly within the shovel frame 4 through the connection of the pull rope 41. Then, through the meshing transmission of the meshing teeth between the pull rod 77 and the sector disk 725, the sector disk 725 reciprocates. Through the transmission action of the approach rod 723, the indexing rod 721 reciprocates synchronously within the annular groove 71, thereby driving the cleaning ring 73 set below to rotate synchronously.

[0030] Step 3: When the template 00 is conveyed by the conveying roller 2 to the position below the cleaning ring 73, the friction plate 741 first adheres to the upper surface of the template 00 and undergoes adaptive deformation and bending. Subsequently, as the cleaning ring 73 rotates, the cleaning rod 74 rotates circumferentially and drives the friction plate 741 below it to rotate synchronously. The friction plate 741 polishes the upper surface of the template 00 and cleans the residue.

[0031] Step 4: During the reciprocating deflection of the vertical shaft 6, the upper actuating rod 63 is driven to reciprocate within a certain angle. Then, through the limiting effect between the front "U"-shaped structure and the lower roller of the actuating block 51, the actuating block 51 is made to reciprocate linearly in the horizontal direction. The actuating block 51 causes the parallel wire cutting cables 5 on both sides of the base frame 1 to reciprocate linearly, and then the wire cutting cables 5 reciprocate within a certain angle. Through the blocking and linear cutting effect of the wire cutting cables 5, the residue adhering to the upper surface of the template 00 is peeled off and decomposed.
