Abstract
Description
Technical Field
[0001] This invention belongs to the field of railway sleeper processing technology, and particularly relates to a railway sleeper conveying and grouping device and its manufacturing process. Background Technology
[0002] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems:
[0003] In traditional technology, sleepers are transported sequentially, making it impossible to group them. When stacking, they need to be transported in groups of four, stacked in four piles. This sequential transport method makes it difficult to group the sleepers, which is not conducive to the subsequent forklift transfer and storage after stacking.
[0004] CN211944962U - A conveying device for a sleeper truss destacking mechanism discloses a conveying device for a sleeper truss destacking mechanism. This device is installed at the output end of the sleeper truss destacking mechanism and includes two transversely parallel conveyor chains and a drive shaft that drives the conveyor chains. The drive shaft and conveyor chains are driven by sprockets. A drive motor is also provided on the frame, and the drive motor is chain-driven with the drive shaft. When the drive motor is working, it drives the drive shaft to rotate, thereby driving the conveyor chains. Several V-shaped supports are evenly arranged along the length of the conveyor chains. When the sleeper truss destacking mechanism outputs a single sleeper truss, the sleeper truss falls into the corresponding V-shaped support. However, this method cannot solve the aforementioned technical problem. Summary of the Invention

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.
[0047] See Figure 1-5 A sleeper conveying and grouping device, comprising:
[0048] The frame consists of a frame 1, a longitudinal main beam 2 mounted on the frame 1, a slide rail 3 mounted on the longitudinal main beam 2, and multiple sets of slider mechanisms slidably mounted on the slide rail 3. Each set of slider mechanisms includes at least two sliders 4. Adjacent sliders in each set of slider mechanisms are connected by a movable connecting piece 14. The movable connecting piece 14 has a U-shaped hole, and the slider has a movable pin 13 that matches the U-shaped hole of the movable connecting piece 14. The movable pin 13 can slide within the U-shaped hole. The slider can support the sleeper. The frame column is equipped with a longitudinal main beam 2, and the main beam is equipped with a slide rail 3. Twelve sets of sliders 4 are provided for placing the sleeper.
[0049] Adjacent slider mechanisms are connected by a fixed connecting piece 15; the slider mechanism is provided with a fixed pin adapted to the fixed connecting piece 15; the sliders are connected to the movable pin 13 on the slider by connecting pieces, and the four groups of sliders are connected by a movable connecting piece 14 with a U-shaped hole. The connecting piece 15 is a fixed connecting piece, used for 4 sleepers in 1 group, with a gap between the groups.
[0050] The drive mechanism drives the slider mechanism to slide on the slide rail 3. The drive mechanism is a chain mechanism; the chain mechanism has a chain 12 and a sprocket; the sprocket is rotatably mounted on the longitudinal main beam 2, the chain 12 is wound around the sprocket, and the slider mechanism is connected to the chain 12; it also has a power mechanism to drive the sprocket. The power mechanism includes a motor 5 and a reducer 6; the motor 5 and reducer 6 are mounted on the frame 1; the rotating shaft of the motor 5 is connected to the transmission shaft 9 of the sprocket through the reducer 6. The reducer 6 includes a reducer 6, a pinion 7, and a gear 8; the reducer 6 is connected to the rotating shaft of the motor 5, the pinion 7 is connected to the reducer 6, and the gear 8 is fixedly connected to the transmission shaft 9; the gear 8 meshes with the pinion 7. The drive part consists of a motor 5, a reducer 6, a pinion 7, a gear 8, a driving sprocket 11, a driven sprocket 11-1, and a chain 12. A fixing pin 16 is mounted on the chain 12 and fixedly connected to the last slider 4-1. The large gear 8 and two sprockets are fixed on the transmission shaft 9, and the transmission shaft 9 is fixed to the frame through two bearing seats.
[0051] The slider mechanism consists of three groups; each group has four sliders 4. The number of sliders in the slider mechanism can be changed according to the actual stacking quantity. A connecting rod 16 is fixedly installed on the chain 12, and the connecting rod 16 is fixedly connected to the end slider 4-1 of the end slider mechanism.
[0052] Working principle: After being demolded from the 1*12 sleeper mold, the sleepers are evenly placed on the slider. To facilitate stacking and forklift transport in the next process, four sleepers need to be grouped together, with sufficient gaps between each group. This device achieves grouping during the transport to the next workstation.
[0053] Initially, the equipment is in the sleeper demolding initial position, with 12 sleepers evenly placed on the slider. The motor is started, and the drive chain propels slider 4-1 forward. After the fixed pin on the slider is pushed into the U-shaped hole between the connecting pieces and subjected to force, it continues to push the next slider forward until the sleepers are grouped as shown. Then, all sliders simultaneously continue to push forward until the motor stops at the next station. At the next station, the grouped sleepers are removed and stacked. The motor is then started in reverse, and the chain propels the slider back to the initial position. The grouping mechanism stacks the sleepers in groups of four, four stacks, facilitating forklift transport and storage after the next stacking step.
[0054] The steps for using a multi-slider mechanism include:
[0055] 1) Multiple sets of slider mechanisms are in their initial positions;
[0056] 2) After the 12 sleepers are demolded from the mold, they are placed on the slider by a logistics trolley;
[0057] 3) Start the motor, and the transmission chain drives the slider forward. After the movable pin on the slider is pushed into the U-shaped hole of the movable connecting piece and subjected to force, it continues to push the next slider forward until the sleeper grouping is completed. The fixed connecting piece locks the distance between the front and rear slider mechanisms, keeping the distance between each group of sleepers at 15cm.
[0058] 4) The drive chain continues to drive the end slider forward, and all sliders continue to move forward simultaneously to the next station, at which point the motor stops;
[0059] 5) At the next workstation, the stacker will grab, transport, and stack the 12 sleepers in three separate trips.
[0060] 6) Reverse start the motor, and the chain drives the slider back to the initial position.
[0061] In step 2) above, the spacing between each sleeper is 15cm; the movable spacing of the U-shaped hole is 15cm, and the inner sleeper under stress has no gap.
[0062] The manufacturing process of railway sleepers includes the following steps:
[0063] 1) Automatic cleaning of 1×12 double-block sleeper molds;
[0064] 2) Manually inspect the mold cleaning process, clean hard-to-reach areas, and vacuum the dust;
[0065] 3) Automatically spray the mold with release agent, extract and remove the residual release agent after atomization, and perform cleaning treatment;
[0066] 4) Install the pre-embedded sleeve;
[0067] 5) Hoist the welded steel truss into the formwork;
[0068] 6) Lock the steel truss after it has been placed in the formwork;
[0069] 7) When pouring concrete, the vibration is carried out using a permanent magnet attached bottom vibration method;
[0070] 8) After the concrete has initially set, stack the molds in 3 or 4 layers to prepare for steam curing;
[0071] 9) Steam curing of railway sleepers;
[0072] 10) After steam curing, disassemble the stacked molds and rotate them 180 degrees to prepare for demolding;
[0073] 11) Loosen the sleeve bolts and use the vibration mold to separate the sleeper from the mold;
[0074] 12) After demolding, the sleepers enter the conveying and grouping device; the mold is cleaned and enters the next cycle.
