The device and method for quickly positioning a ballastless track steel formwork, through the projection lights in the left and right groups of horizontally arranged radiation adjustment parts, can quickly adjust the position of the entire device through self-locking rollers before placing the steel formwork while reducing errors and ensuring positioning accuracy. At the same time, during the installation of the steel formwork, the radiation adjustment part can move with it into the interior of the connecting frame, which greatly shortens the time for positioning and placing the steel formwork.

[0004] The above-mentioned equipment has certain deficiencies when performing installation operations on steel formwork structures. The steel formwork structure is composed of multiple groups of side forms and one group of bottom forms, and the above-mentioned equipment can only complete the installation operation of one group of side forms at a time when in use, and the side form position needs to be repeatedly positioned during repeated installation, which reduces its work efficiency; at the same time, the above-mentioned equipment does not have a multiple positioning structure. When it performs the installation operations on the side forms and bottom forms of the steel formwork structure, it is necessary to manually calibrate the side forms and the bottom forms, which increases its installation difficulty and has a single functionality; secondly, when the above-mentioned equipment performs the installation operations on the side forms and bottom forms of the steel formwork structure, it is necessary to manually complete the side form loading operation. When repeatedly assembling multiple groups of steel formworks, the side form loading operation cannot be automatically completed, and it does not have an auxiliary feeding structure, which reduces its use effect.

[0026] During operation, in order to complete the precise docking between the bottom mold and the side mold, the first positioning member, the second positioning member and the mover are used to respectively position the two groups of side molds and the bottom mold, so that the side molds are accurately installed on the upper end of the bottom mold. The first positioning member and the second positioning member use the lifting base plate at the bottom thereof to pick up and fix the two groups of side molds, and the side molds are translated to the upper end of the bottom mold by the movement of the moving frame, so that the side molds and the bottom mold complete the docking operation. When the side molds are picked up and installed, the positioning guide column can be used to complete the positioning operation between the lifting base plate and the side mold. When the lifting base plate and the side mold are aligned, the electric push rod is used to drive the sliding block, so that the sliding block drives the moving buckle to move, so as to complete the docking and fixation of the lifting base plate and the side mold. The lifting base plate is driven by the lifting rod to make The lifting base plate drives the side mold to move up and down to complete the docking operation between the side mold and the bottom mold. During operation, the caster frame of the mover is used to move to both sides of the bottom mold of the steel template, and the two sides of the bottom mold are fixed by positioning the side plates and the positioning clamps. The positions of the first positioning member and the second positioning member are adjusted by the two-way screw rod, and the first positioning member and the second positioning member are moved to the top of the storage box, and the side mold is fixed to the bottom of the lifting base plate.

[0042] To solve the problem of rapid positioning during the installation of steel formwork structures, such as Figure 2As shown, guide rods 12 are provided on both sides of the lifting rod 11 between the lifting base plate 8 and the movable slider 13. The two groups of movable sliders 13 are driven by a bidirectional screw rod 14. A motor 4 is provided at one end of the movable frame 5. In order to complete the precise docking between the bottom mold 27 and the side mold 28, the first positioning member 3, the second positioning member 7 and the mover 1 are used to respectively position the two groups of side molds 28 and the bottom mold 27, so that the side mold 28 is accurately installed on the upper end of the bottom mold 27. The first positioning member 3 and the second positioning member 7 use the lifting base plate 8 at the bottom thereof to pick up and fix the two groups of side molds 28. The side mold 28 is translated to the upper end of the bottom mold 27 by the movement of the movable frame 5, so that the side mold 28 and the bottom mold 27 complete the docking operation.

[0043] To solve the installation problems of steel formwork structures of different specifications, such as Figure 3 As shown, the movable buckle 9 and the lifting base plate 8 as well as the positioning guide column 10 and the lifting base plate 8 are movably connected via the sliding block 15. The interior of the lifting base plate 8 is provided with an electric push rod 16 used in conjunction with the movable buckle 9. When the side mold 28 is picked up and installed, the positioning guide column 10 can be used to complete the positioning operation between the lifting base plate 8 and the side mold 28. When the lifting base plate 8 and the side mold 28 are aligned, the sliding block 15 is driven by the electric push rod 16, so that the sliding block 15 drives the movable buckle 9 to move, thereby completing the docking and fixation of the lifting base plate 8 and the side mold 28. The lifting base plate 8 is driven by the lifting rod 11, so that the lifting base plate 8 drives the side mold 28 to move up and down, thereby completing the docking operation between the side mold 28 and the bottom mold 27.

[0044] To solve the problem of accurate positioning during the installation of steel formwork structures, such as Figure 4 As shown, a support seat 23 is movably installed on the other side of the caster frame 18, and a lifting support plate 17 is installed on the lower end of the support seat 23 through a hydraulic rod. The support seat 23 and the caster frame 18 are movably connected through a second cross bar 22, and the caster frame 18 and the positioning side plate 19 are movably connected through a first cross bar 21. The positions of the positioning side plate 19 and the support seat 23 can be adjusted respectively by using the first cross bar 21 and the second cross bar 22. The support seat 23 plays an auxiliary supporting role for the mover 1, through which the stability of the moving frame 5 can be improved, and the positioning side plate 19 assists in fixing the side of the bottom mold 27, and plays an auxiliary positioning role when the bottom mold 27 and the side mold 28 are docked.

[0045] like Figure 4 As shown, two groups of positioning clamps 20 are fixedly installed on the outer surface of the side of the positioning side plate 19, the first cross bar 21 and the second cross bar 22 are staggered, and a transverse slide groove 6 is provided at the upper end of the movable frame 5. The positioning clamps 20 are inserted into the grooves of the bottom mold 27 by moving the positioning side plate 19, so that the first positioning member 3 and the second positioning member 7 are precisely placed directly above the bottom mold 27.

[0046] Solve the feeding problem during the installation of steel formwork structure, such as Figure 5 As shown, two groups of storage boxes 2 are fixedly installed on one side of the mobile frame 5. The storage boxes 2 and the mobile frame 5 are docked and fixed by installing a mounting base 26. The storage boxes 2 are used to carry the side mold 28, which facilitates the first positioning member 3 and the second positioning member 7 to perform installation operations on the side mold 28.

[0047] Two sets of limit card plates 24 are spliced ​​and installed on the inner side of the storage box 2, and a telescopic top block 25 is movably installed between the limit card plates 24 on the inner side of the storage box 2. When the side mold 28 is installed, the limit card plates 24 and the telescopic top block 25 play a role of limiting and fixing the two ends and sides of the side mold 28, so that the storage box 2 can be suitable for the installation operation of side molds 28 of different specifications.

[0048] like Figure 6 As shown, the side mold 28 is spliced ​​and installed on the upper outer surface of the bottom mold 27. The side mold 28 and the bottom mold 27 are spliced ​​and fixed by a docking rod 30. The upper end of the side mold 28 is provided with a groove used to cooperate with the movable buckle 9 and the positioning guide column 10. The side mold 28 and the bottom mold 27 are spliced ​​and fixed by the docking rod 30, so that the side mold 28 and the bottom mold 27 are precisely docked after splicing, thereby improving the installation accuracy.

[0049] like Figure 7 As shown, the two sets of side molds 28 are fixed together by docking sleeves 29 in cooperation with the card slots. The outer surface of the side edge of the bottom mold 27 is provided with a card slot used to cooperate with the positioning clamp 20. The docking sleeves 29 cooperate with the card slots to enable the two sets of side molds 28 to be accurately docked, thereby improving the docking accuracy of the steel template structure.

[0050] A method for using a ballastless track steel formwork rapid positioning device comprises the following steps:

[0051] Step 1: Use the caster frame 18 of the mover 1 to move to both sides of the steel template bottom mold 27, and fix both sides of the bottom mold 27 through the positioning side plates 19 and the positioning clamps 20;

[0052] Step 2: Use the bidirectional screw 14 to adjust the positions of the first positioning member 3 and the second positioning member 7, move the first positioning member 3 and the second positioning member 7 to the top of the storage box 2, and fix the side mold 28 to the bottom of the lifting base plate 8;

[0053] Step three, move the side mold 28 to the upper end of the bottom mold 27 through the first positioning member 3 and the second positioning member 7, and move the side mold 28 downward so that the side mold 28 and the bottom mold 27 are docked and fixed by the docking rod 30. After the four sets of side molds 28 are installed, the installation operation of the roadbed plate steel mold structure is completed.

[0054] When in use, the steel formwork structure is composed of multiple sets of side forms 28 and one set of bottom forms 27, while the conventional equipment can only complete the installation operation of one set of side forms 28 at a time, and the position of the side forms 28 needs to be repeatedly positioned when repeatedly installed, which reduces its working efficiency;

[0055] To this end, by providing the first positioning member 3 and the second positioning member 7, when the ballastless track steel formwork rapid positioning device is used, it is possible to simultaneously complete the installation operation of two sets of steel formwork structure side forms 28, and at the same time, there is no need to perform position calibration during repeated installation operations, so that the positioning operation of the steel formwork structure is quickly completed, thereby improving the installation efficiency of the steel formwork structure;

[0056] During operation, in order to complete the precise docking between the bottom mold 27 and the side mold 28, the first positioning member 3, the second positioning member 7 and the mover 1 are used to respectively position the two groups of side molds 28 and the bottom mold 27, so that the side mold 28 is accurately installed on the upper end of the bottom mold 27. The first positioning member 3 and the second positioning member 7 use the lifting base plate 8 at the bottom thereof to pick up and fix the two groups of side molds 28, and the side mold 28 is translated to the upper end of the bottom mold 27 by the movement of the moving frame 5, so that the side mold 28 and the bottom mold 27 complete the docking operation. When the side mold 28 is picked up and installed, the positioning guide column 10 can be used to complete the positioning operation between the lifting base plate 8 and the side mold 28. When the lifting base plate 8 and the side mold 28 are aligned, the electric push rod 16 is used to drive the sliding block 15, so that the sliding block 15 drives the moving buckle 9 to move, so as to complete the docking and fixation of the lifting base plate 8 and the side mold 28, and the lifting base plate is driven by the lifting rod 11 8, so that the lifting base plate 8 drives the side mold 28 to move up and down, and completes the docking operation between the side mold 28 and the bottom mold 27. During the operation, the caster frame 18 of the mover 1 is used to move to the two sides of the bottom mold 27 of the steel template, and the two sides of the bottom mold 27 are fixed by the positioning side plates 19 and the positioning clamps 20. The positions of the first positioning member 3 and the second positioning member 7 are adjusted by the bidirectional screw rod 14, and the first positioning member 3 and the second positioning member 7 are moved to the top of the storage box 2, and the side mold 28 is fixed to the bottom of the lifting base plate 8. The side mold 28 is moved to the upper end of the bottom mold 27 by the first positioning member 3 and the second positioning member 7, and the side mold 28 is moved downward, so that the side mold 28 and the bottom mold 27 are docked and fixed by the docking plug rod 30. After the four sets of side molds 28 are installed, the installation operation of the roadbed plate steel mold structure is completed, so that the installation operation of two sets of side molds 28 can be completed in a single time, thereby improving its work efficiency;

[0057] The conventional equipment does not have a multiple positioning structure. When the side mold 28 and the bottom mold 27 of the steel formwork structure are installed, the side mold 28 and the bottom mold 27 need to be manually calibrated, which increases the difficulty of installation and has a single function.

[0058] To this end, by providing a mover 1, when the ballastless track steel formwork rapid positioning device is used, it has a multiple positioning structure, thereby improving the installation accuracy of the ballastless track steel formwork structure and avoiding the misalignment phenomenon when assembling the steel formwork structure;

[0059] When in use, the mover 1 can use the first cross bar 21 and the second cross bar 22 to adjust the positions of the positioning side plates 19 and the support seats 23 respectively. The support seats 23 play an auxiliary supporting role for the mover 1, through which the stability of the moving frame 5 can be improved, and the positioning side plates 19 assist in fixing the sides of the bottom mold 27, and play an auxiliary positioning role when the bottom mold 27 and the side mold 28 are docked, thereby improving their installation accuracy. When it is performing the side mold 28 installation operation, the positioning clamping head 20 is inserted into the card slot of the bottom mold 27 by moving the positioning side plates 19, and the position calibration of the bottom mold 27 and the moving frame 5 is completed, so that when the moving frame 5 is performing the side mold 28 installation operation, the first positioning member 3 and the second positioning member 7 are accurately placed directly above the bottom mold 27. Secondly, when the moving frame 5 is performing the side mold 28 installation operation, the lifting support plate 17 at the bottom of the support seat 23 is driven downward by the hydraulic rod, so that the lifting support plate 17 contacts the ground, which can play an auxiliary fixing role for the moving frame 5 and improve its stability.

[0060] Secondly, when the traditional equipment is performing the installation operation of the side form 28 and the bottom form 27 of the steel formwork structure, it is necessary to manually complete the loading operation of the side form 28. When the assembly operation of multiple sets of steel formworks is repeated, the loading operation on the side form 28 cannot be automatically completed, and there is no auxiliary feeding structure, which reduces its use effect;

[0061] To this end, by providing a storage box 2, when the ballastless track steel formwork rapid positioning device is used, it has an auxiliary feeding structure, and by providing the storage box 2 on both sides of the mobile frame 5, the mobile frame 5 can continuously perform installation operations on multiple sets of bottom molds 27 and side molds 28, thereby improving its use effect;

[0062] During operation, the storage box 2 is used to carry the side mold 28, which is convenient for the first positioning member 3 and the second positioning member 7 to perform installation operations on the side mold 28.
