Description

Technical Field

[0001] The invention belongs to the technical field of treatment of demolished concrete solid waste, and in particular relates to a device for recycling and treating bridge demolished concrete solid waste. Background Art

[0002] After years of operation, bridges experience a decline in load-bearing capacity and a variety of complex and serious defects. Even reinforcement efforts are unlikely to meet demand, while expansion is prohibitively expensive. Consequently, bridges must be dismantled and rebuilt. Currently, the most widely used method for building demolition involves using a variety of machinery to cut or crush bridges into larger concrete solid waste, which is then transported to a processing plant for crushing and recycling. However, replacing demolition equipment during construction consumes significant time, and transporting the demolished concrete solid waste consumes significant transportation resources and manpower.

[0003] After searching, the publication number CN110194358A is a bridge demolition construction solid waste auxiliary recovery device, which includes a steel plate, a vehicle body, a demolition component, a buffer component, a collection box, two mobile components and two guide rails, the two guide rails are symmetrically arranged on the top of the steel plate, the vehicle body is arranged on the two guide rails, and the bottom end of the vehicle body is provided with four rectangularly distributed moving wheels, the four moving wheels are all located in the two guide rails, the demolition component is installed on the top of the vehicle body, the buffer component is installed on the top of the vehicle body, and the buffer component is located on the side of the demolition component, the collection box is installed on the top of the buffer component, and the two mobile components are symmetrically arranged on both sides of the top of the vehicle body; the demolition component demolishes the bridge to be demolished, and the demolished stones fall into the collection box. When the demolished stones fall into the collection box, the buffer component buffers the collection box to prevent the collection box from being damaged by excessive force; however, during the demolition process, the size of the solid waste dropped by the demolition is uneven, and the volume of the solid waste that falls into the collection box in an instant is immeasurable, which can easily cause a demolition accident;

[0004] After searching, the publication number CN117123315A is a method for preparing construction solid waste concrete and its alkali reduction treatment method, which includes a crushing component and a screening component. First, the construction solid waste at the construction site is collected by a construction solid waste collection device. During the collection process, recyclable solid waste is selected through manual primary screening. The initially recovered construction solid waste is then crushed by the screening component. The crushed construction solid waste forms recycled aggregate. Finally, the recycled aggregate is screened in multiple stages according to particle size using the screening component. Although the device can be used for on-site construction to treat construction solid waste, the early collection process requires manual primary selective recovery, which reduces the convenience and versatility of equipment recycling.

[0005] In view of this, a bridge demolition concrete solid waste recycling and processing device is proposed, which can directly crush and recycle the demolished concrete solid waste while automatically replacing equipment to demolish the bridge. Summary of the Invention

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1) Hydraulic motor III can control the rotation of mounting box I by meshing the gear on the output end with the gear teeth at the bottom of rotating seat I, making it easier for the cutter and breaker to demolish the bridge from multiple angles.

[0013] 2) Hydraulic motor I controls the threaded rod to drive the cutting machine to rise, retract or descend to cut and decompose the bridge; when the cutting machine remains in the retracted state, the hydraulic motor II can be controlled to cooperate with the gear to control the sliding plate I to slide along the slide groove on the installation box I. When the connecting box is located directly below the installation box I, the breaker hammer can break the bridge concrete. Since the breaker hammer cannot handle the steel bars inside the bridge body, after the breaker hammer completes the breaking of the bridge concrete, it is necessary to control the hydraulic cylinder I to push the hydraulic shear so that the sliding seat I contacts the bottom of the sliding plate II. After the sliding plate II contacts the bottom of the slide groove on the connecting box, the hydraulic cylinder I is controlled to continue to extend, so that the hydraulic shear rotates with the connection point between the sliding seat I and the hydraulic shear as the axis to cut the steel bars, preventing the concrete blocks broken by the breaker hammer from being unable to be completely disconnected from the bridge due to the steel bar connection. At the same time, the motor in the installation box I cooperates with the gear on the output end and the gear teeth on the connecting seat I to control the rotation of the connecting box, so that the hydraulic shear can It can shear steel bars at any inclined angle; after completing cutting or crushing and shearing, the hydraulic motor II controls the sliding plate I to drive the installation box II to move to the bottom of the installation box I. Since the hydraulic cylinder II and the hydraulic cylinder III can be controlled independently, the connecting rod and the clamping rod can be controlled to rotate at different angles according to the characteristics of the concrete surface, so that the connecting rod and the clamping rod can better fit the concrete surface to grab it. At the same time, the motor in the installation box II cooperates with the gear on the output end and the gear on the connecting seat I to control the rotation of the installation box II according to the concrete placement angle, so that the connecting rod and the clamping rod can better fit the concrete surface to grab it; then the demolition device cooperates with the mechanical arm and the sliding turntable to put the concrete solid waste clamped by the connecting rod and the clamping rod into the crushing box I. Through the multi-stage integrated chain action of crushing, shearing, cutting and grabbing, the bridge demolition is just right to cope with the complex on-site processing environment;

[0014] 3) Hydraulic cylinder IV extends, controlling the mounting plate to drive the vibration plate close to the concrete. At the same time, hydraulic cylinder VI extends and contracts to control the triangular prism blade to change its angle. Hydraulic motor IV drives the eccentric wheel to rotate, thereby controlling the vibration plate to drive the triangular prism blade to crush the concrete from different angles, further changing the internal stress of the concrete and causing cracks on the concrete surface. After the quadrangular hammer head and crushing block hammer into the concrete, the force points on the contact surface of the concrete are different. Hydraulic cylinder V extends and contracts to control the movement of the crushing block and side blade knife to squeeze and crush the concrete, further causing the concrete to be broken quickly. After the crushing is completed, the manipulator slides along the guide rail to pick up the steel bars mixed in the concrete fragments into the slide. The steel bars slide along the slide and accumulate on the side of the vehicle body for subsequent recovery. Finally, hydraulic motor V is turned on to make the conveyor chain transport the concrete fragments to the drop port.

[0015] 4) Concrete fragments enter the crushing box II through the discharge port, are crushed into recycled aggregates by the crushing roller, and then fall onto the screening belt to screen the recycled aggregates into two aggregates of different sizes, making it convenient to apply aggregates of different sizes to different recycling methods; the large aggregates are transported to the discharge port II by the screening belt, and sent out of the device through the discharge port II to wait for transportation, and the smaller aggregates pass through the screening belt and fall onto the conical baffle. The strong magnetic strips in the conical mounting box screen the metal waste in the aggregate and adsorb it on the surface of the conical baffle to prevent the metal waste from falling into the bottom of the screening cylinder with the aggregate and being reused together with the aggregate, causing engineering quality problems; then the motor I controls the rotation of the conical mounting box, and the adsorbed metal waste slides on the surface of the conical baffle into the through groove on the conical baffle. At the same time, the hydraulic cylinder VII extends and the hydraulic cylinder VIII retracts, so that the bottom of the scraper fits on one side of the through groove on the conical baffle, The waste is scraped into the groove on the conical baffle. When the groove on the conical mounting box coincides with the groove on the conical baffle, the metal waste falls into the receiving barrel and is transported to the outside of the device through the spiral discharging machine, so as to continuously adsorb and collect the metal waste mixed in the aggregate, thereby realizing the recycling and reuse of metal resources; at the same time, the hydraulic motor Ⅶ controls the connecting seat Ⅱ to drive the roller Ⅰ to roll along the arc chute at the top of the support column. When the roller Ⅰ moves to the highest point of the arc chute at the top of the support column, the roller Ⅰ lifts the connecting column, so that the connecting column drives the conical baffle and the conical mounting box to swing under the restriction of the limit rod Ⅰ and the limit rod Ⅱ, thereby reducing the time that the aggregate stays on the conical baffle, preventing the aggregate from accumulating on the conical baffle and affecting the adsorption effect of the strong magnetic strip in the conical mounting box on the metal waste. Finally, the aggregate accumulated at the bottom of the screening drum is sent out of the device through the discharge port Ⅰ. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A bridge demolition concrete solid waste recycling and treatment device, the working process is as follows:

[0032] The hydraulic motor Ⅰ 203 controls the threaded rod 2031 to drive the cutter 202 to rise, retract or descend to cut and decompose the bridge; when the cutter 202 remains in the retracted state, the hydraulic motor Ⅱ 204 can be controlled to cooperate with the gear 2041 to control the sliding plate Ⅰ 206 to slide along the slide groove on the installation box Ⅰ 201. When the connecting box 207 is located directly below the installation box Ⅰ 201, the breaker hammer 2071 can break the bridge concrete. Since the breaker hammer 2071 cannot handle the steel bars inside the bridge body, it is necessary to control the hydraulic motor Ⅱ 204 ... The pressure cylinder I 2073 pushes the hydraulic shear 2074, so that the sliding seat I 2075 contacts the bottom of the sliding plate II 2076. After the sliding plate II 2076 contacts the bottom of the chute on the connection box 207, the hydraulic cylinder I 2073 is controlled to continue to extend, so that the hydraulic shear 2074 rotates with the connection point between the sliding seat I 2075 and the hydraulic shear 2074 as the axis to cut the steel bar, preventing the concrete blocks broken by the breaker 2071 from being completely disconnected from the bridge due to the steel bar connection. At the same time, the motor in the installation box I 2072 cooperates with the gear on the output end and the gear on the connection seat I 2062 to control the connection box. 207 rotates, so that the hydraulic shear 2074 can cut the steel bars at any inclined angle; after the cutting or crushing is completed, the hydraulic motor II 204 controls the sliding plate I 206 to drive the installation box II 208 to move to the bottom of the installation box I 201. Since the hydraulic cylinder II 2081 and the hydraulic cylinder III 2083 can be controlled independently, the connecting rod 2084 and the clamping rod 2085 can be controlled to rotate at different angles according to the characteristics of the concrete surface, so that the connecting rod 2084 and the clamping rod 2085 can better fit the concrete surface to grab it, and at the same time the installation box II 208 The motor in 2 cooperates with the gear on the connecting seat I 2062 through the gear on the output end, and controls the rotation of the installation box II 208 according to the concrete placement angle, so that the connecting rod 2084 and the clamping rod 2085 can better fit the concrete surface to grab it; then the demolition device 2 cooperates with the mechanical arm 8 and the sliding turntable 5 to put the concrete solid waste clamped by the connecting rod 2084 and the clamping rod 2085 into the crushing box I 101, and completes the bridge demolition just right through the multi-stage integrated chain action of crushing, shearing, cutting and grabbing to cope with the complex on-site processing environment. Then, hydraulic cylinder IV 3011 extends, controlling mounting plate 301 to drive vibration plate 302 close to the concrete. Simultaneously, hydraulic cylinder VI 3023 retracts and controls triangular prism blade 3021 to change its angle. Hydraulic motor IV 304 rotates eccentric wheel 3041, thereby controlling vibration plate 302 to drive triangular prism blade 3021 to crush the concrete from different angles, further changing the stress within the concrete. When the quadrangular pyramid hammer head 3012 and crushing block 3014 are inserted into the concrete, hydraulic cylinder V 3013 retracts and controls the movement of crushing block 3014, squeezing and crushing the concrete, causing the force points on the concrete contact surface to differ.After the crushing is completed, the manipulator 7 slides along the guide rail 1013 and picks the steel bars mixed in the concrete fragments into the slide 305. The steel bars slide along the slide 305 and accumulate on the side of the vehicle body 1 for subsequent recycling. Finally, the hydraulic motor V 306 is turned on to make the conveyor chain plate 3061 transport the concrete fragments to the drop port 1012. The concrete fragments pass through the drop port 1012 and enter the crushing box II 4013. After being crushed into recycled aggregates by the crushing roller 402, they fall onto the screening belt 4031 to screen the recycled aggregates into two kinds of aggregates of different sizes, which is convenient for applying the different sizes of aggregates to different recycling methods. The large aggregates are The screening belt 4031 is transported to the discharge port II 4014, and then sent to the outside of the device through the discharge port II 4014 to wait for transportation. The smaller aggregate passes through the screening belt 4031 and falls on the conical baffle 4056. The strong magnetic strip in the conical mounting box 4057 screens the metal waste in the aggregate and adsorbs it on the surface of the conical baffle 4056, preventing the metal waste from falling into the bottom of the screening drum 4011 with the aggregate and being reused together with the aggregate, causing engineering quality problems. Then the motor I 408 controls the rotation of the conical mounting box 4057, and the adsorbed metal waste slides on the surface of the conical baffle 4056 into the through groove on the conical baffle 4056. At the same time, the hydraulic cylinder VII4 052 extends, and the hydraulic cylinder VIII 4055 retracts, so that the bottom of the scraper 4053 is attached to one side of the through groove on the conical baffle 4056, and the metal waste is scraped into the through groove on the conical baffle 4056. When the through groove on the conical mounting box 4057 coincides with the through groove on the conical baffle 4056, the metal waste falls into the receiving barrel 404 and is transported to the outside of the device through the spiral discharger 4041, thereby continuously adsorbing and collecting the metal waste mixed in the aggregate, realizing the recycling and reuse of metal resources; at the same time, the hydraulic motor VII 407 controls the connecting seat II 4071 to drive the roller I 4072 along the top of the support column 406 When roller I 4072 reaches the highest point of the curved chute at the top of support column 406, roller I 4072 lifts connecting column 4054, causing connecting column 4054 to swing under the constraints of limit rods I 4061 and II 4062, thereby reducing the time that aggregate remains on conical baffle 4056 and preventing it from accumulating on conical baffle 4056 and affecting the strong magnetic strips in conical mounting box 4057's ability to attract metal scrap. Finally, aggregate accumulated at the bottom of screening drum 4011 is discharged from the device through discharge port I 4012.
