[0002] The ballastless track adopted by high-speed railways has the advantages of good smoothness, good stability, long service life, good durability and less maintenance work, and the large-scale laying of the ballastless track structure on high-speed railways has become a development trend. The quality control points of the ballastless track engineering mainly lie in precision control, steel bar insulation and concrete crack control, and the effectiveness of the steel bar insulation treatment and the advantages and disadvantages of the insulation quality directly affect the track circuit transmission performance and the stability after being put into use. The steel bar insulation treatment mainly adopts the mode of penetrating the insulation pipe on the ordinary steel bar and then solidifying through the heat shrinking process. Since there are multiple intersections of steel bars in the steel bar mesh, in order to realize the insulation of the steel bar intersection points, multiple insulation pipes need to be penetrated on each steel bar at different set positions. At present, the penetration of the insulation pipe is mainly performed manually, a large amount of labor cost is needed, the labor intensity of workers is large, the penetration efficiency is low, and the insulation pipe is prone to displacement. Therefore, in view of the low efficiency and uncontrollable quality of the manual installation of the heat shrinking insulation pipe, it is urgent to develop an automatic insulation pipe penetrating device.

[0052] The working process of the reinforcing steel bar supply system is as follows: a bundle of unpacked reinforcing steel bars is first hoisted into the stock bin frame of the reinforcing steel bar separating device, the magnetic plate adsorbs a plurality of reinforcing steel bars, the electric roller rotates, the reinforcing steel bars adsorbed on the magnetic plate are hindered by the reinforcing steel bar separating mounting seat, fall off the magnetic plate, and fall on the inclined material receiving table. The start and stop of the electric roller are controlled by three buried proximity switches; the highest buried proximity switch detects reinforcing steel bars, and the electric roller stops rotating; the lowest buried proximity switch must always be in a sensing state; the middle position buried proximity switch does not detect reinforcing steel bars, and the electric roller rotates to feed in reinforcing steel bars. The reinforcing steel bars falling on the inclined material receiving table are adsorbed by the uniform distribution magnetic seat, twelve magnets are uniformly distributed in a uniform distribution magnetic seat along the circumference, the magnets can be selected, the size (adsorption force) of the magnets in the uniform distribution magnetic seat is restricted, two uniform distribution magnetic seats can only adsorb one reinforcing steel bar at a time, the rotating shaft provided with the uniform distribution magnetic seat is driven by the driving motor to rotate 30° each time (the rotating angle is the same as the angle between every two adjacent magnets in the uniform distribution magnetic seat), and one reinforcing steel bar can be adsorbed each time; the dial plate is installed on the driving shaft, and every three dial rod blocks are uniformly distributed in a dial plate along the circumference; the driving shaft provided with the dial plate is driven by the motor of the chain conveyor to rotate 120° each time (the rotating angle is the same as the angle between every two adjacent dial rods on the dial plate), and one reinforcing steel bar can be pushed off from the uniform distribution magnetic seat each time, the pushed-off reinforcing steel bar falls on the chain, and is sequentially fed back to the V-shaped groove along the chain.

[0053] The working process of the insulating tube supply system is as follows: Insulating tubes are manually poured into a vibratory feeder, which can hold 800-1000 tubes. The vibratory feeder feeds the tubes spirally to its outlet, where they enter the guide groove of the linear vibrating guide rail. At this point, the tilting shaft drive cylinder is in the position of the limit lever end low and the stop lever end high. The limit lever is pressed down to block the insulating tube until a supply command is issued. Then, the tilting shaft drive cylinder extends, the limit lever rises, and the first insulating tube is released and moves in the guide groove. Simultaneously, the limit lever rises and the stop lever presses down, blocking the second insulating tube. The first insulating tube moves linearly along the guide groove, powered by the linear vibrator. After the laser sensor detects the first insulating tube, the drive cylinder rotates, the limit lever lowers, and the stop lever rises. The second insulating tube moves from the stop lever to the limit bolt, where it is blocked, awaiting a supply command. This process is repeated to complete the supply of insulating tubes to the synchronous conveyor belt. When the insulating tube is conveyed on the synchronous conveyor belt, the two lifting cylinders rise simultaneously, with the push plate positioned outside the U-shaped plate. The last blocking cylinder pushes down, and after it is pushed into place, the blocking block is located on the surface of the synchronous conveyor belt. The first insulating heat shrink tube is released onto the synchronous conveyor belt. When the laser sensor detects it, the last blocking cylinder pushes down, and the first insulating tube stops at the last blocking cylinder, simultaneously positioned behind the corresponding push plate. Then the second insulating tube is released. In this manner and sequence, the blocking cylinders from the end to the beginning push down in turn. After the laser sensor detects the set number of tubes, the synchronous conveyor belt stops running. Then, the two lifting cylinders descend simultaneously, all blocking cylinders rise simultaneously, and the push plate cylinders push out simultaneously. The push plate pushes the positioned insulating tube into the corresponding receiving groove in the lower mold on the rotating hub, where it is suctioned and positioned by the air hole.

[0054] The working process of the pipe-through system is as follows: after the steel bar falls into the V-shaped groove, the lower mold of one row of the rotating hub carrying the insulating pipe rotates to the lower side of the upper mold, the rotating hub stops, the upper beam driving cylinder drives the row of the upper mold to descend, after descending, each upper mold enters the flat groove in the corresponding lower mold, the upper mold descends to the set position, at this time, the upper arc-shaped groove and the lower arc-shaped groove are located on a circle, and the corresponding insulating pipe in the containing groove also becomes circular, after the upper mold descends to the set position, the steel bar pushing device pushes the steel bar in the V-shaped groove to move forward and backward to pass through the insulating pipe in each lower mold in turn, after pushing to the position, the swing cylinder acts, the push plate is lifted, and at the same time, the pushing cylinder reverses, the steel bar end is reset backward. After the reset is completed, the swing cylinder reverses, the steel bar end swings downward, and the next time the steel bar is pushed. The lower mold of the other row of the insulating pipe loading station of the uppermost end row of the lower mold loads the insulating pipe when the steel bar is through. After the steel bar is through, the upper beam driving cylinder drives the upper mold to ascend, after the insulating pipe in the lower mold is through the steel bar, the insulating pipe continues to rotate with the rotating hub to the next station, when reaching the steel bar removing station, the steel bar after the insulating pipe is through can be removed from the lower mold by relying on the gravity of the steel bar itself or be pushed down from the mold by relying on the action of the steel bar removing device through the pawl, and then is put on the chain conveying bed of the heat shrinkage furnace system to be heat shrunk.
