[0026] At the same time, the present invention also discloses a ballastless track laying method with simple steps, reasonable design, convenient implementation and good use effect, characterized in that the method comprises the following steps:

[0027] The method comprises the following steps:

[0028] Step 1: Set the ballastless track laying conditions:

[0029] Set the working condition of ballastless track laying to base plate pouring or roadbed slab pouring;

[0030] Step 2: Installation of the material placing device for ballastless track construction:

[0031] Step 201: Construction workers install the support frame on the ballastless track to be constructed; wherein the traveling mechanism is installed in the cable trench, and the crossbeam is arranged transversely along the ballastless track to be constructed;

[0032] Step 202: The gate plates in the two gate components are closed to close the discharge port at the bottom of the hopper, and the hopper filled with concrete is placed under the crossbeam through the support legs;

[0033] Step 203: operate the boom component to grab and suspend the hopper containing concrete;

[0034] Step 3: Operational judgment of ballastless track laying:

[0035] When the base plate needs to be poured, execute step 4; when the roadbed plate needs to be poured, execute step 5;

[0036] Step 4: Use the ballastless track construction device to pour the base plate:

[0037] Step 401: The controller controls the travel motor through the travel motor driver to operate. The travel motor drives the travel wheel to move along the bottom of the cable trench until the hopper moves to the designed starting position for construction. The guide wheel moves along the groove of the cable trench.

[0038] Step 402: The controller controls the transverse motor via the transverse motor driver. The transverse motor drives the reducer to rotate. The rotation of the reducer drives the rotating shaft and the sliding wheel to slide along the beam through the driving gear, the chain, and the driven gear, thereby driving the hopper to slide along the beam until the hopper moves to the position directly above the left-line pouring design construction position.

[0039] Step 402: Operate the traveling wheels to move at a constant speed along the bottom of the cable trench. Simultaneously, control the gate hydraulic cylinder to retract. The retraction of the gate hydraulic cylinder drives the gate plates to open through the transition plate and the lower U-shaped frame until the opening of the two gate plates meets the pouring design requirements. Then, the concrete in the hopper is poured into the left line base plate template through the discharge port.

[0040] Step 403: While the hopper moves with the traveling wheels to pour concrete, the traveling encoder detects the distance traveled by the ballastless track construction placing device and sends the detected travel distance to the controller.

[0041] When the concrete pouring in the current hopper is completed, the controller compares the driving distance received at that moment with the pouring distance setting value. If the driving distance is less than the pouring distance setting value, step 404 is executed; otherwise, step 405 is executed.

[0042] Step 404: operate the boom assembly to lower and disassemble the currently empty hopper, and then grab and suspend another hopper filled with concrete according to the method described in steps 202 and 203;

[0043] Step 405: Repeat steps 402 and 403 until the driving distance received by the controller is equal to the set value of the pouring distance, completing the left line pouring of the first working surface pouring section;

[0044] Step 406: The controller controls the transverse motor through the transverse motor driver. The transverse motor drives the reducer to rotate in the opposite direction. The rotation of the reducer drives the rotating shaft and the sliding wheel to slide in the opposite direction along the beam through the driving gear, the chain, and the driven gear. This in turn drives the hopper to slide in the opposite direction along the beam until the hopper moves to the position directly above the right-line pouring design construction position.

[0045] Step 407: According to the method described in steps 402 to 405, the concrete in the hopper is poured into the right line base plate template through the discharge port, completing the first working surface pouring section of the right line pouring;

[0046] Step 408: Repeat steps 402 and 407 multiple times until the left-line base plate and the right-line base plate are cast.

[0047] Step 5: Use the ballastless track placement device to pour the trackbed slab:

[0048] According to the method described in step four, the concrete in the hopper is poured into the left-lane roadbed slab template or the right-lane roadbed slab template through the discharge port until the pouring of the left-lane roadbed slab and the pouring of the right-lane roadbed slab are completed.

[0049] The above method is characterized in that: in step 203, the suspension rod component is operated to grab and suspend the hopper containing concrete, and the specific process is as follows:

[0050] Step 2031: Extend the piston rod of the suspension hydraulic cylinder to bring the hook close to the hanging rod on the hopper;

[0051] Step 2032: Adjust the extension of the piston rod of the hydraulic cylinder. The extension of the piston rod of the hydraulic cylinder drives one end of the two lower tilt links to swing through the U-shaped hinge seat. The other ends of the two lower tilt links drive the connecting shaft to swing through the upper vertical link. The swinging of the connecting shaft drives the hooks at the bottom ends of the piston rods of the two suspension hydraulic cylinders to move closer to each other, so that the two hooks are located between the inner sides of the two hanging rods.

[0052] Step 2033: Control the piston rod of the suspension hydraulic cylinder to continue extending and adjust the piston rod of the hydraulic cylinder to retract, so that the hooks move away from each other and hook onto the hanging rod on the hopper until the upper vertical connecting rod and the suspension beam are arranged vertically; wherein the suspension hydraulic cylinder is arranged vertically;

[0053] Step 2034: The piston rod of the suspension hydraulic cylinder contracts, and the hopper is driven to rise through the hook until the bottom height of the hopper meets the construction design requirements.

[0054] The above method is characterized in that: in step 404, the boom component is operated to lower and disassemble the hopper, and the specific process is as follows:

[0055] Step 4041: The gate hydraulic cylinder extends and closes the two gates to close the discharge port at the bottom of the hopper; wherein the gate hydraulic cylinder extends and swings the lower end of the transition plate away from the lower U-shaped frame crossbar to separate the transition plate from the lower U-shaped frame crossbar;

[0056] Step 4042: Extend the piston rod of the suspension hydraulic cylinder so that the hopper is placed under the beam via the support legs.

[0057] Step 4043: Regulate the extension of the piston rod of the hydraulic cylinder to drive the hooks at the bottom ends of the piston rods of the two suspension hydraulic cylinders to move closer to each other;

[0058] At the same time, the piston rod of the suspension hydraulic cylinder is retracted, so that the hooks are separated from the hanging rod during the process of the hooks approaching each other, until the suspension hydraulic cylinder is arranged vertically;

[0059] Step 4044: manually take out the hopper.

[0060] Compared with the prior art, the present invention has the following advantages:

[0061] 1. The present invention has a simple structure, reasonable design, easy installation and layout, convenient operation, and realizes the automation of concrete pouring of the base plate and the roadbed plate.

[0062] 2. The boom component used can not only realize the lifting and raising of the hopper containing concrete, but also realize the lowering and unloading of the hopper when the concrete pouring in the hopper is completed, thereby reducing manual participation in the process of grabbing and lifting the hopper.

[0063] 3. The power components used are to ensure that the first sliding seat and the second sliding seat slide along the direction of the crossbeam, and then realize the sliding of the hopper along the direction of the crossbeam, so as to effectively cast the left and right line base plates and roadbed plates in the ballastless track, and the adjustment is convenient.

[0064] 4. The traveling mechanism used can not only enable the ballastless track construction placing device to move along the cable trench of the ballastless track to be constructed, but also drive the hopper during the walking process to realize the pouring work of the hopper in the extension direction of the double-block ballastless track, which can meet the length requirements of the double-block ballastless track.

[0065] 5. The first sliding seat and the second sliding seat are used, on the one hand, to be able to be mounted on the first beam and the second beam, thereby driving the hopper to slide along the length direction of the first beam and the second beam, realizing the casting of the left and right line base plates and the roadbed plates in the ballastless track, and increasing the casting range; on the other hand, it is for the integrated layout of the boom components and the gate components, which is compact as a whole.

[0066] 6. The boom components used are, on the one hand, for grabbing the bucket and replacing the bucket, so as to adapt to the long-distance working surface casting; on the other hand, for lifting and lowering the bucket, and suspending the bucket under the first beam and the second beam, and meeting the casting distance adjustment requirements.

[0067] 7. The ballastless track laying method of the present invention has simple steps, is easy to implement and simple to operate, and ensures uniform laying of the ballastless track.

[0068] 8. The ballastless track laying method of the present invention has a good use effect. First, the ballastless track laying working conditions are set, followed by the installation of the ballastless track construction laying device, and then the ballastless track laying operation is judged. When it is necessary to cast the base plate, the ballastless track construction laying device is used to cast the base plate; when it is necessary to cast the track bed plate, the ballastless track construction laying device is used to cast the track bed plate.

[0069] In summary, the present invention has a reasonable design, realizes the grabbing, lifting, lateral movement and travel of the hopper, and can quickly complete the casting of the left and right line base plates and roadbed plates in the ballastless track without frequent manual intervention, saving manpower and material resources and improving construction efficiency.

[0168] like Figure 12 A ballastless track laying method shown includes the following steps:

[0169] The method comprises the following steps:

[0170] Step 1: Set the ballastless track laying conditions:

[0171] Set the working condition of ballastless track laying to base plate pouring or roadbed slab pouring;

[0172] Step 2: Installation of the material placing device for ballastless track construction:

[0173] Step 201: Construction workers install the support frame on the ballastless track to be constructed; wherein the traveling mechanism is installed in the cable trench, and the crossbeam 3 is arranged transversely along the ballastless track to be constructed;

[0174] Step 202: The gate plates 21-7 in the two gate components are closed to close the discharge port at the bottom of the hopper 8, and the hopper 8 filled with concrete is placed under the crossbeam 3 through the support legs 8-1;

[0175] Step 203: operate the boom component to grab and suspend the hopper 8 filled with concrete;

[0176] Step 3: Operational judgment of ballastless track laying:

[0177] When the base plate needs to be poured, execute step 4; when the roadbed plate needs to be poured, execute step 5;

[0178] Step 4: Use the ballastless track construction device to pour the base plate:

[0179] Step 401: The controller 2 controls the travel motor 4-3 via the travel motor driver 19 to operate. The travel motor 4-3 drives the travel wheel 4-2 to move along the bottom of the cable trench until the hopper 8 moves to the designed starting position for construction. The guide wheel 4-4 moves along the end of the cable trench.

[0180] Step 402: The controller 2 controls the traverse motor 10 via the traverse motor driver 10-1. The traverse motor 10 drives the reducer 11 to rotate. The reducer 11 drives the rotating shaft 7-4 and the sliding wheel 7-5 to slide along the beam 3 through the driving gear 12, the chain 13, and the driven gear, thereby driving the hopper 8 to slide along the beam 3 until the hopper 8 moves to the position directly above the left-line pouring design construction position.

[0181] Step 402: Operate the traveling wheel 4-2 to move at a constant speed along the bottom of the cable trench. At the same time, control the gate hydraulic cylinder 21-4 to retract. The gate hydraulic cylinder 21-4 retracts, driving the gate plate 21-7 to open through the transition plate 21-5 and the lower U-shaped frame 21-6 until the opening of the two gate plates 21-7 meets the pouring design requirements. Then, the concrete in the hopper 8 is poured into the left line base plate template through the discharge port.

[0182] Step 403: While the hopper 8 is moving along with the traveling wheels 4-2 to pour concrete, the traveling encoder 12 detects the distance traveled by the ballastless track construction placing device and sends the detected travel distance to the controller 2.

[0183] When the concrete pouring in the current hopper 8 is completed, the controller 2 compares the driving distance received at that moment with the pouring distance setting value. If the driving distance is less than the pouring distance setting value, step 404 is executed; otherwise, step 405 is executed.

[0184] Step 404: operate the boom assembly to lower and disassemble the currently empty hopper 8, and according to the method described in steps 202 and 203, grab and suspend another hopper 8 filled with concrete;

[0185] Step 405: Repeat steps 402 and 403 until the driving distance received by the controller 2 is equal to the set value of the pouring distance, and the left line pouring of the first working surface pouring section is completed;

[0186] Step 406: The controller 2 controls the traverse motor 10 via the traverse motor driver 10-1. The traverse motor 10 drives the reducer 11 to rotate in the opposite direction. The reducer 11 drives the rotating shaft 7-4 and the sliding wheel 7-5 to slide in the opposite direction along the beam 3 through the driving gear 12, the chain 13, and the driven gear. This drives the hopper 8 to slide in the opposite direction along the beam 3 until the hopper 8 moves to the position directly above the right-line pouring design construction position.

[0187] Step 407: According to the method described in steps 402 to 405, the concrete in the hopper 8 is poured into the right line base plate template through the discharge port, completing the first working surface pouring section of the right line pouring;

[0188] Step 408: Repeat steps 402 and 407 multiple times until the left-line base plate and the right-line base plate are cast.

[0189] Step 5: Use the ballastless track placement device to pour the trackbed slab:

[0190] According to the method described in step four, the concrete in the hopper 8 is poured into the left-lane roadbed slab template or the right-lane roadbed slab template through the discharge port until the pouring of the left-lane roadbed slab and the pouring of the right-lane roadbed slab are completed.

[0191] In this embodiment, in step 203, the hopper 8 containing concrete is grabbed and suspended by operating the boom component. The specific process is as follows:

[0192] Step 2031: The piston rod of the suspension hydraulic cylinder 15 is extended so that the hook 15-2 is close to the hanging rod 8-2 on the hopper 8;

[0193] Step 2032: Adjust the extension of the piston rod of the hydraulic cylinder 20-2. The extension of the piston rod of the hydraulic cylinder 20-2 drives one end of the two lower tilt links 20-4 to swing through the U-shaped hinge seat 20-3. The other ends of the two lower tilt links 20-4 drive the connecting shaft 15-1 to swing through the upper vertical link 20-5. The swinging of the connecting shaft 15-1 drives the hooks 15-2 at the bottom ends of the piston rods of the two suspension hydraulic cylinders 15 to move closer to each other, so that the two hooks 15-2 are located between the inner sides of the two hanging rods 8-2.

[0194] Step 2033: Control the piston rod of the suspension hydraulic cylinder 15 to continue extending and the piston rod of the adjustment hydraulic cylinder 20-2 to retract, so that the hooks 15-2 are hooked onto the hanging rod 8-2 on the hopper 8 while moving away from each other, until the upper vertical connecting rod 20-5 and the suspension beam 9 are arranged vertically; wherein the suspension hydraulic cylinder 15 is arranged vertically;

[0195] Step 2034: The piston rod of the suspension hydraulic cylinder 15 contracts, driving the hopper 8 to rise through the hook 15-2 until the bottom height of the hopper 8 meets the construction design requirements.

[0196] In this embodiment, in step 404, the boom component is operated to lower and disassemble the hopper 8. The specific process is as follows:

[0197] Step 4041: The gate hydraulic cylinder 21-4 extends and closes the two gates 21-7 to close the discharge port at the bottom of the hopper 8; wherein, the gate hydraulic cylinder 21-4 extends and swings through the lower end of the transition plate 21-5 away from the cross bar of the lower U-shaped frame 21-6, so that the transition plate 21-5 is separated from the cross bar of the lower U-shaped frame 21-6;

[0198] Step 4042: The piston rod of the suspension hydraulic cylinder 15 is extended so that the hopper 8 is placed below the crossbeam 3 via the support legs 8-1.

[0199] Step 4043: Regulate the extension of the piston rod of the hydraulic cylinder 20-2 to drive the hooks 15-2 at the bottom ends of the piston rods of the two suspension hydraulic cylinders 15 to move closer to each other;

[0200] At the same time, the piston rod of the suspension hydraulic cylinder 15 contracts, so that the hooks 15-2 are separated from the hanging rod 8-2 during the process of the hooks 15-2 approaching each other, until the suspension hydraulic cylinder 15 is arranged vertically;

[0201] Step 4044: manually remove the hopper 8;

[0202] In this embodiment, the pouring distance is set to 100 meters to 200 meters.

[0203] In this embodiment, the construction starting design position, the left-line pouring design construction position, and the right-line pouring design construction position only need to meet the construction requirements.

[0204] In this embodiment, the suspension hydraulic cylinder 15 swings around the mounting hole 9 - 2 via the connecting shaft 15 - 1 so that the hooks 15 - 2 move closer to or farther away from each other.

[0205] In this embodiment, during actual use, the outer cover of the gas spring 16 is provided with a foldable protective cover to prevent concrete from contaminating the gas spring 16, and the concrete on the foldable protective cover can be cleaned; in addition, the diameter of the limiting hole 21-7-3 is larger than the diameter of the positioning shaft 8-3 to ensure flexible rotation.

[0206] To sum up, the structure is simple and the design is reasonable, which can realize the grabbing, lifting, lateral movement and driving of the hopper, and can quickly complete the casting of the left and right line base plates and roadbed plates in the ballastless track without frequent manual intervention, saving manpower and material resources and improving construction efficiency.

[0207] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
