Description

Technical Field

[0001] This invention relates to the technical field of trapezoidal sleeper production equipment, specifically to a trapezoidal sleeper production equipment and its usage method based on the long-line pedestal method. Background Technology

[0002] Currently, the production efficiency of concrete placing equipment for trapezoidal sleepers still has room for improvement compared to the ever-increasing market demand. Some placing machines have relatively slow placing speeds, especially when facing large-scale production tasks, where the placing process can easily become a bottleneck in the entire production process. At the same time, the connection between different processes is not smooth enough. For example, in the process of transporting concrete from the mixing plant to the placing machine, manual assistance is required. This might involve using trucks to transport hoppers to the mixing plant for receiving the concrete, then placing them under a crane, which lifts the hoppers and moves them onto the sleeper molds for placing. This process can be prolonged due to inaccurate equipment positioning or cumbersome procedures, often resulting in excess concrete spillage that requires manual cleanup. Overall, the placing efficiency is low, and the existing placing process uses a single hopper, which results in slow and inaccurate placing speeds for the double-strip trapezoidal sleepers. Summary of the Invention

[0003] The purpose of this invention is to provide a trapezoidal sleeper production equipment and its usage method based on the long-line pedestal method. This equipment solves the problem in the prior art that manual assistance is required during the ash transportation process from the mixing plant to the concrete placing machine. It also solves the problems of slow concrete placing speed and low precision in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A trapezoidal sleeper production equipment based on the long-line pedestal method includes multiple production lines arranged in parallel and spaced intervals, as well as a main truss, a transverse truss, a double-bottom ash-feeding machine, a cantilever truss, a material transport car, a transfer hopper, and a controller; the main truss is set on the outside of the multiple production lines; the transverse truss is slidably mounted on the main truss and is used to drive the double-bottom ash-feeding machine to move along the length of the production line; The material transport vehicle is slidably mounted on the transverse truss, and the double-bottom ash outlet material placing machine is installed on the material transport vehicle. The material transport vehicle drives the double-bottom ash outlet material placing machine to move along the length of the transverse truss. The double-bottom ash outlet material placing machine can place materials on multiple production lines separately. The cantilever truss is installed on one side of the production line. The cantilever truss includes a support frame, a cantilever frame, and diagonal bracing. The cantilever frame is cantilevered on one side of the support frame and is located above the transverse truss. The diagonal bracing is installed on both sides of the support frame and the cantilever frame. The transfer hopper is slidably installed on the cantilever truss; when the transfer hopper moves to one end of the cantilever truss, it is located below the mixing plant's discharge hopper to accurately receive materials; when the transfer hopper moves to the other end of the cantilever truss, it is located above the double-discharge material placing machine to prepare for material feeding. The controller is used to control the movement of the material transport vehicle, the movement of the transverse truss on the main truss, and the material placement of the double-lower gray-outlet material placing machine.

[0005] Preferably, a weighing device is installed on the material transport vehicle, and the double-bottom ash outlet concrete feeder is installed on the weighing device; the weighing device is used to control the double-bottom ash outlet concrete feeder to accurately feed materials; the weighing device is electrically connected to the controller.

[0006] Preferably, the double-feeding-outlet material feeder has two independent feeding bins, and the controller can control the opening and closing of the two feeding bins individually.

[0007] Preferably, the length of the main truss is not less than 150m; the span of the transverse truss is not less than 20m; and the length of the cantilever truss is not less than 12m.

[0008] Preferably, a monitor is installed on the double-bottomed ash-feeding machine, and the monitor is electrically connected to the controller.

[0009] Preferably, tensioning tables are provided at both ends of the production line, and retractable canopies are provided above the tensioning tables.

[0010] A method for using a trapezoidal sleeper production equipment based on the long-line pedestal method, the method comprising the following steps: Step 1: The transfer hopper receives the ash. The operator remotely controls the transfer hopper to move below the mixing plant's hopper via the controller. The mixing plant then pours the pre-mixed concrete into the transfer hopper. After the transfer hopper has received the ash, it is moved to the other end of the cantilever truss under the control of the controller. Step two: The double-bottom ash-feeding concrete placing machine receives ash. The operator remotely controls the double-bottom ash-feeding concrete placing machine to move to the end of the transfer hopper via the controller. At the same time, the operator moves the double-bottom ash-feeding concrete placing machine laterally to the corresponding position. When the ash-feeding port of the double-bottom ash-feeding concrete placing machine is directly below the transfer hopper, the operator opens the discharge switch of the transfer hopper via the controller, and the concrete slides into the double-bottom ash-feeding concrete placing machine, completing the ash-feeding process. Step 3: The double-bottom concrete placing machine places concrete. The operator remotely controls the transverse truss to move longitudinally along the main truss via the controller, and simultaneously controls the material transport vehicle to move laterally along the transverse truss. When the double-bottom concrete placing machine is above the trapezoidal sleeper mold, and the two discharge bins of the double-bottom concrete placing machine are directly above the two strip plates of the sleeper, the on-site operator uses the remote control switch to open the discharge bin switch, allowing concrete to flow into the trapezoidal sleeper mold. At the same time, the operator operates the remote control switch to slowly move the transverse truss. Another operator operates the vibrator attached to the trapezoidal sleeper mold to place and vibrate the concrete simultaneously. After pouring one trapezoidal sleeper, the above operation process is repeated for the remaining trapezoidal sleepers.

[0011] In this invention, the weighing device accurately measures the mass of ash receiving and discharging, achieving precise material distribution. The double-discharge ash-feeding machine has two discharge bins, improving distribution efficiency. The monitoring system allows personnel to operate the system from a central control room and observe the real-time operation.

[0012] The cantilevered truss structure can solve the problem of the 12-meter distance difference between the material discharge port of the mixing plant and the double-feeding-outlet concrete placing machine, thus solving the problems of high labor intensity and low efficiency in manual transportation and improving the efficiency of concrete placing.

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 5The illustrated trapezoidal sleeper production equipment based on the long-line pedestal method includes multiple parallel and spaced production lines 1. In this embodiment, two or three production lines 1 are arranged according to production requirements, and multiple trapezoidal sleeper molds are set on each production line 1. Tensioning tables 12 are set at both ends of the production line 1. The tensioning tables 12 are used to apply precise prestress to the reinforcing bars and maintain the tension state of the reinforcing bars during pouring. A telescopic awning 13 is set above the tensioning tables 12. The telescopic awning 13 can be used to seal the concrete after pouring, and steam curing is carried out inside the awning for heat preservation and moisture retention.

[0015] The equipment also includes a main truss 2, a transverse truss 3, a double-bottomed concrete placing machine 4, a cantilever truss 5, a material transport car 6, a transfer hopper 7, and a controller 8. The main truss 2 is located outside the multiple production lines 1, and its length is no less than 150m. Tracks for the movement of the transverse truss 3 are installed on the main truss 2. A laser rangefinder is installed at one end of the main truss 2 to detect the movement position of the transverse truss 3.

[0016] The transverse truss 3 is slidably mounted on the main truss 2, used to drive the double-bottom ash-feeder placing machine 4 to move along the length of the production line 1. In this embodiment, a traveling mechanism is provided on the transverse truss 3. This traveling mechanism travels on a track, and the operator controls the movement and stopping of the traveling mechanism through the controller 8 to control the longitudinal position of the double-bottom ash-feeder placing machine 4. The span of the transverse truss 3 is not less than 20m. The traveling mechanism can be a traveling mechanism from a commercially available truss overhead crane. A laser rangefinder sensor is provided at one end of the transverse truss 3. This laser rangefinder sensor is used to detect the moving position of the double-bottom ash-feeder placing machine 4.

[0017] The material transport trolley 6 is slidably mounted on the transverse truss 3. The double-bottom ash-feeding material placing machine 4 is installed on the material transport trolley 6. The material transport trolley 6 drives the double-bottom ash-feeding material placing machine 4 to move along the length of the transverse truss 3. The double-bottom ash-feeding material placing machine 4 can place material on multiple production lines 1 separately. The specific structure of the material transport trolley 6 can be selected from the traveling mechanism of a truss crane. A track for the material transport trolley 6 to travel is provided on the transverse truss 3. The operator controls the movement and stopping of the traveling mechanism through the controller 8, thereby controlling the lateral position of the double-bottom ash-feeding material placing machine 4.

[0018] A weighing device 9 is installed on the material transport vehicle 6, and a double-bottom concrete placing machine 4 is mounted on the weighing device 9. The weighing device 9 is used to control the double-bottom concrete placing machine 4 to accurately pour a specified amount of concrete into each sleeper mold. The weighing device 9 is electrically connected to the controller 8, and the amount of concrete poured by the double-bottom concrete placing machine 4 each time is transmitted to the controller 8. The weighing device 9 can be equipped with a weight sensor.

[0019] The double-feeding-outlet concrete placing machine 4 has two independent feeding bins 10, and the controller 8 can control the opening and closing of the two feeding bins 10 individually. During pouring, the controller 8 controls the opening and closing of the feeding bins 10 according to the mass reduction of the weighing device 9, so as to achieve precise material placement.

[0020] In a preferred embodiment, a monitor 11 is installed on the double-bottom ash-outlet concrete placing machine 4, and the monitor 11 is electrically connected to the controller 8. During the pouring operation, the monitor 11 monitors the operation of the double-bottom ash-outlet concrete placing machine 4 in real time and uploads the data to the central control room. The operator can grasp the overall pouring situation based on the real-time images transmitted by the monitor 11.

[0021] A cantilever truss 5 is installed on one side of the end of production line 1. The cantilever truss 5 includes a support frame 50, a cantilever frame 51, and a diagonal brace 52. The cantilever frame 51 is welded and cantilevered on one side of the support frame 50, and is located above the transverse truss 3. The diagonal brace 52 is fixedly installed on both sides of the support frame 50 and the cantilever frame 51, increasing the structural strength of the cantilever frame 51. In this embodiment, the overall length of the cantilever truss 5 is not less than 12m, the cantilever length of the cantilever frame 51 is 4m, and the upper end of the cantilever frame 51 is 4160mm from the workshop floor.

[0022] The transfer hopper 7 is slidably mounted on the cantilever truss 5 via a traveling mechanism. This traveling mechanism can be a commercially available truss crane mechanism or another mechanism capable of controlling the movement of the transfer hopper 7. The traveling speed of the traveling mechanism is 30 m / min. When the transfer hopper 7 moves to one end of the cantilever truss 5, it is positioned below the mixing plant's discharge hopper, accurately receiving material. When the transfer hopper 7 moves to the other end of the cantilever truss 5, it is positioned above the double-discharge concrete placing machine 4, ready to discharge material. In a preferred embodiment, a weighing device 9 is also provided between the transfer hopper 7 and the traveling mechanism. This weighing device 9 can accurately discharge 1 cubic meter of concrete into the two independent discharge hoppers 10 of the double-discharge concrete placing machine 4. The weighing device 9 can be a weight sensor. The transfer hopper 7 has a volume of not less than 2.2 cubic meters and a hydraulic door opening and closing mechanism.

[0023] The controller 8 is used to control the movement of the material transport vehicle 6, the movement of the transverse truss 3 on the main truss 2, and the material placement of the double-bottom ash-feeding machine 4. The controller 8 is a PLC programmable controller.

[0024] like Figures 1 to 5 The illustrated method for using a trapezoidal sleeper production equipment based on the long-line pedestal method includes the following steps: Step 1: Transfer hopper 7 receives ash. The operator remotely controls the transfer hopper 7 to move below the mixing plant's discharge hopper via controller 8 in the central control room. The mixing plant then discharges the pre-mixed concrete into the transfer hopper 7. After the transfer hopper 7 has received the ash, it is moved to the other end of the cantilever truss 5 under the control of controller 8.

[0025] Step two: The double-bottom ash-feeding concrete placing machine 4 receives concrete. The operator remotely controls the double-bottom ash-feeding concrete placing machine 4 via the controller 8 to move it to the end of the transfer hopper 7. At the same time, the operator moves the double-bottom ash-feeding concrete placing machine 4 laterally to the corresponding position. When the concrete receiving port of the double-bottom ash-feeding concrete placing machine 4 is directly below the transfer hopper 7, the operator opens the discharge switch of the transfer hopper 7 via the controller 8, and the concrete slides into the double-bottom ash-feeding concrete placing machine 4, completing the concrete receiving process.

[0026] Step 3: The double-bottom concrete placing machine 4 places concrete. The operator remotely controls the transverse truss 3 to move longitudinally along the main truss 2 via the controller 8, and simultaneously controls the material transport vehicle 6 to move laterally along the transverse truss 3. When the double-bottom concrete placing machine 4 is above the trapezoidal sleeper mold, and the two discharge bins 10 of the double-bottom concrete placing machine 4 are respectively directly above the two strip plates of the sleeper, the on-site operator uses the remote control switch to turn on the switch of the discharge bin 10, allowing the concrete to flow into the trapezoidal sleeper mold. At the same time, the remote control switch is operated to control the transverse truss 3 to move slowly. Another operator operates the vibrator attached to the trapezoidal sleeper mold to place and vibrate the concrete simultaneously. After one trapezoidal sleeper is poured, the above operation process is repeated for the remaining trapezoidal sleepers.

[0027] As the two independent discharge hoppers 10 of the double-discharge concrete placing machine 4 move longitudinally from one end of the mold to the other, concrete is discharged and moved along the same time. The concrete has filled 2 / 3 of the mold, and at the same time, it is vibrated by a vibrator, causing the concrete to settle due to its density. Then, the double-discharge concrete placing machine 4 is operated to move back, and the concrete is discharged again to fill the sleeper mold, while vibrating it along the same time.

[0028] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
