Description

Technical Field

[0001] The invention relates to the field of tunnel and bridge engineering, and in particular to a ring reinforcement distributing device. Background Art

[0002] During construction, circular or arc-shaped steel bar structures are often used in bridge piers, tunnel linings, culverts, chimneys, nuclear power containment vessels, and pipe corridors.

[0003] At present, steel bars are generally tied manually at the construction site. When tying steel bars on site, all the ring bars that need to be tied are generally placed manually according to the set distance, and then the ring bars are tied at the corresponding positions of the straight bars. Before tying the ring bars, it is necessary to first fix the top / bottom ring bars as the "reference ring bars", and then use a plumb line and a horizontal tube to control the verticality and horizontality based on this standard, and position each ring bar one by one. Especially for tying steel arches with larger diameters, a crane is generally required to transport the ring bars to the corresponding positions. During the hoisting, the ring bars may be deformed, resulting in some ring bars being unusable. In addition, more tools are required when positioning and distributing the ring bars one by one, resulting in low efficiency in positioning and distributing the ring bars. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the current manual positioning and distribution of ring bars requires many steps, and the ring bars may be deformed and unusable during the lifting and auxiliary positioning of the ring bars. In addition, more tools are required when positioning and distributing the ring bars one by one, resulting in low efficiency in positioning and distributing the ring bars. The purpose is to provide a ring bar material distribution device that automatically positions and distributes multiple ring bars at one time according to the set distance and position, and prevents the ring bars from deforming during transportation, thereby replacing the manual positioning and distribution of the ring bars one by one and improving work efficiency.

[0005] The present invention is achieved through the following technical solutions: A ring reinforcement material distribution device includes a positioning cross rail, a material transport cross rail and a material transport trolley, the positioning cross rail is connected to the top of the bracket, and several positioning frames are detachably connected to the positioning cross rail; the material transport cross rail is connected to the top of the bracket and is parallel to the positioning cross rail, and the material transport frame is slidably connected to the material transport cross rail; the top of the material transport trolley is connected to the bottom of the material transport frame, and in the working state, the material transport trolley drives the material transport frame to slide along the material transport cross rail, and drives the material transport frame to move downward to distribute several ring reinforcements located on the material transport frame to the corresponding positioning frames; a sliding support structure, when the ring reinforcement is sliding, the sliding support structure supports two symmetrical points on the inner side of the ring reinforcement.

[0006] The lifting of the lifting gear is controlled by the lifting gear of the lifting gear, and the lifting gear is controlled by the lifting gear of the lifting gear to be adjusted. When the lifting gear is adjusted, the lifting gear is controlled by the lifting gear of the lifting gear to be adjusted. When the lifting gear is adjusted, the lifting gear is controlled by the lifting gear. The lifting gear is controlled by the lifting gear.

[0007] In some embodiments, the bracket includes two circular rings and a transverse plate. The open end of the circular ring is mounted on the base. The two ends of the positioning rail and the material transport rail are respectively connected to the top of the corresponding circular ring. The four corners of the transverse plate are respectively connected to the inner side of the upper part of the circular ring. The transverse plate is parallel to the material transport rail. A trolley slide rail is installed on the transverse plate along the length of the transverse plate. In the working state, the material transport trolley slides along the trolley slide rail. By setting the bracket in a circular ring shape and connecting the two transverse rails to the top of the circular ring, it is convenient for the bracket to support the ring ribs to facilitate the positioning of the ring ribs. By setting a transverse plate below the material transport rail and setting a trolley slide rail on the transverse plate, it is convenient for the trolley to run along the trolley slide rail, limiting the sliding path of the trolley, and then allowing the trolley to drive the material transport rack to slide along the material transport rail.

[0008] In some embodiments, the material transport rack includes a support frame and a support rod. The support frame is in the shape of a rectangular frame. The top of the support frame is open, and several positioning grooves are evenly distributed along the length direction of the support frame. The positioning grooves are located at the top of the two side walls of the support frame. The distance between two adjacent positioning grooves is equal to the setting distance between two adjacent annular ribs. The top of the support rod is detachably connected to the bottom of the support frame, and a material transport cylinder is vertically installed on the top of the trolley. The free end of the piston rod of the material transport cylinder is detachably connected to the bottom of the support rod. By setting the support frame into a rectangular frame shape and setting several positioning grooves at the top of the support frame in the longitudinal direction, the inner side of the ring rib is supported at two points, thereby improving the stability and positioning accuracy of the ring rib, and the distance between two adjacent positioning grooves is equal to the setting distance between the two adjacent ring ribs, so that during operation, the ring ribs can be distributed according to the setting distance through the positioning grooves. A material transport cylinder is also set on the top of the trolley, so that when the trolley reaches the bottom of the corresponding positioning frame, the piston rod of the material transport cylinder is retracted, so that the material transport frame and the ring ribs move down synchronously, and the ring ribs are positioned and distributed on the positioning frame.

[0009] In some embodiments, several sliders are also included, which are slidably connected to the positioning cross rail and the material transport cross rail respectively. The structures of the positioning cross rail and the material transport cross rail are the same. Two guide bars are provided at the upper ends of the positioning cross rail and the material transport cross rail. The two guide bars are respectively provided on both sides of the corresponding cross rail. The inner side of the slider is hollow and the bottom is set to be open. Two positioning ridges extending along the length direction are provided on the two inner side walls of the slider. The inner sides of the positioning ridges on the same side wall are respectively engaged with the corresponding guide bars and the top of the cross rail. The material transport rack and the positioning rack can be slidably connected to the corresponding slider up and down. By providing two guide strips at the upper ends of the positioning cross rail and the material transport cross rail, and providing two positioning ridges extending along the length direction on the two inner side walls of the slider, and by respectively engaging the inner sides of the positioning ridges on the two side walls with the corresponding guide strips and the top of the cross rail, the force on both sides of the slider is balanced, and the slider is prevented from tilting or shaking when sliding along the corresponding cross rail, thereby ensuring the stability of the ring ribs positioned on the material transport rack or support rack.

[0010] In some embodiments, the middle portions of the positioning rail and the material transport rail are provided with guide holes, the guide holes vertically passing through the top and bottom portions of the corresponding positioning rail and material transport rail, and extending along the length direction of the corresponding positioning rail and material transport rail. The middle portion of the slider is provided with a positioning through-hole, the positioning through-hole is for the support rod to pass through, the positioning through-hole is tightly fitted with the support rod, and in the working state, the support rod slides along the guide hole. By providing guide holes extending along the length direction of the positioning rail and the material transport rail in the middle portions, and also providing positioning through-holes on the slider, it is convenient for the material transport trolley to drive the support rod and the support frame connected to the support rod to move, and the guide holes are used to limit the movement trajectory of the support rod. By also providing positioning through-holes on the slider for the support rod to pass through, it is convenient for the support rod to move up and down along the positioning through-holes.

[0011] In some embodiments, the present invention further comprises a connecting plate and a positioning cylinder, wherein the positioning frame comprises a positioning frame and a connecting rod, wherein the structure and size of the positioning frame are identical to those of the support frame, the top of the connecting rod is connected to the bottom of the corresponding positioning frame by a thread, and the other end is connected to the connecting plate, the positioning through hole on the slider that matches the positioning rail is tightly matched with the axial hole of the connecting rod, the positioning cylinder is vertically mounted on the cross plate, and the free end of the piston rod of the positioning cylinder is connected to the middle of the connecting plate. By making the structure and size of the positioning frame identical to those of the support frame, it is convenient for the annular reinforcement to be directly unloaded from the support frame to the positioning frame during operation, and by providing a positioning cylinder and connecting the free end of the piston rod of the positioning cylinder to the connecting plate, a plurality of connecting rods are connected to the upper end of the connecting plate, and the other end of the connecting rod is connected to the positioning frame, so that after the annular reinforcement is tied to the main reinforcement, the positioning relationship with the annular reinforcement is released by retracting the piston rod of the positioning cylinder, so that the mobile mechanism can remove the tied annular reinforcement arch from the material distribution device.

[0012] In some embodiments, a central mounting plate is further included, the central mounting plate being in the shape of a rectangular plate, the four corners of the central mounting plate being respectively mounted on the inner sides of the two circular rings, the central mounting plate being located below the transverse plate and parallel to the transverse plate, and radial support plates that can be extended and retracted along the width direction of the central mounting plate are provided at both ends of the central mounting plate, and in the working state, the inner sides of the annular ribs abut against the radial support plates. By providing a central mounting plate and installing radial support plates that can be extended and retracted along the width direction of the central mounting plate on the central mounting plate, the inner sides of the annular ribs can be supported and positioned by the radial support plates during operation, so that the inner sides of the annular ribs are supported at three points, thereby preventing the annular ribs from deforming during transportation and from being displaced and deformed during binding, thereby ensuring the accuracy and stability of the positioning of the annular ribs.

[0013] In some embodiments, two first screw servo motors are further included, wherein the first screw servo motors are installed horizontally along the width direction of the middle mounting plate, the free ends of the screws of the two first screw servo motors are both facing the outside of the middle mounting plate, the screw nuts of the first screw servo motors are connected to the corresponding radial support plates, and the radial support plates are provided with a plurality of support grooves on the side away from the first screw servo motors, each of the support grooves is vertically aligned with the corresponding positioning grooves on the positioning frame, and in the working state, the bottom of the support grooves is against the inner side of the corresponding ring reinforcement. By providing the first screw servo motor, it is convenient to drive the screw nut to move toward the inner side of the ring reinforcement during operation through the servo motor, thereby causing the support grooves on the support plate to abut against the inner side of the corresponding ring reinforcement, supporting and positioning both sides of the ring reinforcement, improving the positioning effect of the ring reinforcement, and also conveniently driving the support plate to move toward the middle mounting plate through the first screw servo motor after the ring reinforcement is tied into a steel bar arch, thereby releasing the positioning of the ring reinforcement, and facilitating the removal of the steel bar arch from the device in the subsequent process.

[0014] In some embodiments, the sliding support structure includes two second screw servo motors and two sliding support blocks. The second screw servo motors are installed horizontally along the width direction of the middle mounting plate. The free ends of the screws of the two second screw servo motors are facing the outside of the middle mounting plate. The screw nuts of the second screw servo motors are connected to the corresponding sliding support blocks. The sliding support blocks are located above the corresponding radial support plates. The free ends of the sliding support blocks are embedded with metal-based self-lubricating plates. The free ends of the metal-based self-lubricating plates are provided with arc tops. In the working state, the arc tops are against the inner side of the annular ribs. During operation, the sliding support block is first pushed to the corresponding position by the second screw servo motor to meet the needs of supporting ring ribs of different diameters. When the ring rib moves with the material transport rack, the inner side of the ring rib slides along the free end of the support block, thereby increasing the supporting force of the ring rib and preventing the ring rib from deforming during the movement and causing the ring rib to become unusable. A metal-based self-lubricating plate is provided at the free end of the sliding support block, and an arc top is provided at the free end of the metal-based self-lubricating plate, so that the inner side of the ring rib is in line contact when sliding along the self-arc top of the metal-based self-lubricating plate, thereby reducing friction. The metal-based self-lubricating plate has both metal strength and self-lubricating properties, and the lubricant is precipitated to form a protective film when worn to protect the inner side of the ring rib, thereby ensuring the quality of the ring rib.

[0015] In some embodiments, several inductive proximity sensor rods are also included, and the inductive proximity sensor rods are installed on the outside of the bottom of the material transport rail. Each of the inductive proximity sensor rods is located on the same vertical plane as the end of the corresponding positioning frame. The inductive proximity sensor rod, material transport cylinder, trolley motor, first screw servo motor and positioning cylinder are all electrically connected to the controller. By installing several inductive proximity sensor rods on the outer side of the bottom of the material transport rail, and locating each of the inductive proximity sensor rods on the same vertical plane as the end of the corresponding positioning frame, when the slider installed on the material transport rail moves to the positioning frame where the ring reinforcement needs to be placed, the inductive proximity sensor rod at the corresponding position outputs a signal to the controller. After receiving the signal, the controller issues a stop command to the trolley motor and issues a retracting piston rod command to the material transport cylinder, so that the ring reinforcement on the material transport frame is unloaded onto the corresponding positioning frame, realizing automatic positioning and distribution of the ring reinforcement. When all the ring reinforcements required for making the steel bar arch are positioned on the corresponding positioning frame, the controller then issues a command to the first screw servo motor to move the support plate toward the inside of the ring reinforcement, further positioning all the ring reinforcements, and ensuring the stability of the ring reinforcement when the steel bars are subsequently tied. After the steel bar arch is made, the first screw servo motor and the positioning cylinder are again instructed to release the positioning of the ring reinforcement on the support plate and the positioning frame.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. By setting up a mobile material transport trolley, several ring reinforcements on the material transport frame are moved synchronously, and the moving ring reinforcements are continuously supported under the action of the sliding support structure to prevent the ring reinforcements from deformation during transportation. When the material transport trolley reaches the designated position, it stops, and under the action of the material transport trolley, the material transport frame is lowered, and the inner sides of the tops of several ring reinforcements on the material transport frame are overlapped with the corresponding positions of the positioning frame. The material transport frame continues to move downward to disengage the material transport frame from the ring reinforcement, and then distributes several ring reinforcements on the positioning frame, so that multiple ring reinforcements can be automatically positioned and distributed at one time according to the set distance and position, thereby improving work efficiency.

[0017] 2. By snapping the inner sides of the positioning ridges on the two side walls into engagement with the corresponding guide bars and the top of the cross rails, the forces on both sides of the slider are balanced, and the slider is prevented from tilting or shaking when sliding along the corresponding cross rails, thereby ensuring the stability of the ring ribs positioned on the transport rack or support frame.

[0018] 3. The inner side of the ring reinforcement is supported and positioned by the radial support plate, so that the inner side of the ring reinforcement forms three points of support to prevent the ring reinforcement from deforming during transportation and displacement and deformation during binding, ensuring the accuracy and stability of the ring reinforcement positioning.

[0019] 4. When the slider installed on the transport rail moves to the positioning frame where the ring ribs need to be placed, the inductive proximity sensor rod at the corresponding position outputs a signal to the controller. After receiving the signal, the controller issues a stop command to the trolley motor and issues a command to the transport cylinder to retract the piston rod, so that the ring ribs on the transport frame are unloaded to the corresponding positioning frame, realizing automatic positioning and distribution of the ring ribs.

By installing several inductive proximity sensor rods 40 on the outer side of the bottom of the material transport rail 20, and locating each of the inductive proximity sensor rods 40 on the same vertical plane as the end of the corresponding positioning frame 211, it is convenient that during operation, when the slider 205 installed on the material transport rail 20 moves to the positioning frame 211 where the ring reinforcement needs to be placed, the inductive proximity sensor rod 40 located at the corresponding position outputs a signal to the controller. After receiving the signal, the controller issues a stop command to the trolley motor 34 and issues a retract piston rod command to the material transport cylinder 204, so that the ring reinforcement located on the material transport frame 201 is unloaded onto the corresponding positioning frame 211, realizing automatic positioning and distribution of the ring reinforcement. After all the ring reinforcement required for making the steel bar arch are positioned on the corresponding positioning frame 211, the controller then issues a command to the first screw servo motor 13 to move the support plate toward the inside of the ring reinforcement, further positioning all the ring reinforcement, and ensuring the stability of the ring reinforcement during subsequent steel bar binding. After the steel bar arch is formed, the first screw servo motor 13 and the positioning cylinder 24 are instructed to release the support plate and the positioning frame 211 from positioning the ring bar. Specifically, a control cabinet is included, in which the controller is installed. The control cabinet is provided with multiple buttons. By pressing corresponding buttons, the controller issues corresponding instructions to the first screw servo motor 13 and the positioning cylinder 24.

[0036] See also Figure 1 and Figure 4The sliding support structure includes two second screw servo motors 132 and two sliding support blocks 142. The second screw servo motors 132 are installed horizontally along the width direction of the middle mounting plate 12. The free ends of the screws of the two second screw servo motors 132 are facing the outside of the middle mounting plate 12. The screw nuts 131 of the second screw servo motors 132 are connected to the corresponding sliding support blocks 142. The sliding support blocks 142 are located above the corresponding radial support plates. The free ends of the sliding support blocks 142 are embedded with a metal-based self-lubricating plate 1421. The free ends of the metal-based self-lubricating plate 1421 are provided with an arc top 1422. In the working state, the arc top 1422 is abutted against the inner side of the annular rib. During operation, the sliding support block 142 is first pushed to the corresponding position by the second screw servo motor 132 to meet the needs of supporting ring ribs of different diameters. When the ring ribs move with the material transport rack 201, the inner side of the ring ribs slides along the free end of the support block, thereby increasing the supporting force of the ring ribs and preventing the ring ribs from deforming during movement, which causes the ring ribs to become unusable. A metal-based self-lubricating plate 1421 is provided at the free end of the sliding support block 142, and the free end of the metal-based self-lubricating plate 1421 is provided with an arc top 1422, so that the inner side of the ring ribs are in line contact when sliding along the self-arc top 1422 of the metal-based self-lubricating plate 1421, thereby reducing friction. The metal-based self-lubricating plate 1421 has both metal strength and self-lubricating properties, and the lubricant precipitates to form a protective film when worn to protect the inner side of the ring ribs, thereby ensuring the quality of the ring ribs. Specifically, the metal-based self-lubricating plate 1421 is composed of a copper / iron matrix + a solid lubricant (graphite, 、 ) is made of metal-based self-lubricating composite materials.

[0037] See also Figure 2 The material transport trolley 30 of the present invention includes a frame 31, four running wheels 32, a transmission shaft 33, and a trolley motor 34. The trolley motor 34 is fixedly connected to the frame 31 and is connected to an input shaft via a coupling. An input sprocket 35 is mounted on the input shaft. The four running wheels 32 include two driving wheels and two driven wheels. The two driving wheels are connected by an output shaft. A driven sprocket is mounted on the output shaft. The driven sprocket and the driving sprocket are connected by a chain 37. The four running wheels 32 are all mounted on the frame 31 via bearings. When the trolley motor 34 rotates, it drives the driving sprocket to rotate, which in turn drives the driven shaft to rotate. The rotation of the driven shaft drives the two running wheels to rotate. The two driven wheels rotate synchronously, causing the trolley to move.
