[0044] As Figures 8 to 11As shown, the auxiliary assembly 8 comprises a sleeve 81 fixedly connected to the end of the two gear wheels respectively, and an industrial camera module 82 fixedly installed on one side of each mounting seat 75, the inner side of the sleeve 81 is fixedly installed with a filling pipe 83, the inner side of the filling pipe 83 is nestedly installed with a plug 84, the plug 84 slides in the inner side of the filling pipe 83, the end of the plug 84 is connected with a U-shaped rod 85, the tail end of the U-shaped rod 85 is connected with a piston plate 86 through a connecting rod, the outer side of the piston plate 86 is sleevedly installed with an oil box 87, the oil box 87 is communicated with the filling pipe 83, the inner side of the filling pipe 83 is nestedly installed with a contact rod 88, the contact rod 88 is fixedly installed on the end of the docking ring 610, by setting the auxiliary assembly 8, when the sleeve 81 is docked with the docking ring 610, the contact rod 88 on one side of the docking ring 610 is docked with the filling pipe 83, the contact rod 88 pushes the plug 84 in the inner side of the filling pipe 83, so that the U-shaped rod 85 slides in the connecting channel between the filling pipe 83 and the oil box 87, the tail end of the U-shaped rod 85 pushes the piston plate 86 to slide in the inner side of the oil box 87, the piston plate 86 pushes the lubricating oil to the channel on one side of the oil box 87, the plug 84 no longer blocks the channel on one side of the oil box 87, the lubricating oil flows into the inner side channel of the docking ring 610 through the opening on one side of the contact rod 88 and the inner side channel, and flows to the surface of the mounting shaft 61, spreads the surface of the mounting shaft 61 and the connecting mechanism, forms an oil film covering layer, and under the action of centrifugal force generated by the rotation of the sleeve 81, the lubricating oil continuously penetrates, so as to uniformly cover the surface of the mounting shaft 61 and the inner side contact surface position of the threaded sleeve 67 and the fixed sleeve 68, which can reduce the mechanical wear between the mounting shaft 61 and each connecting part, reduce the running resistance, also can isolate the moisture and impurities in the air, effectively inhibit the oxidation and corrosion of the metal surface, significantly improve the operation stability and service life of the whole mechanical system.

[0045] The working principle of the technical scheme provided by the application is as follows:

[0046] The operator first lays the reinforcing steel in the sleeper mold 4, passes the mounting shaft 61 through the side wall hole of the sleeper mold 4, selects a gasket 64 of an appropriate size according to the diameter of the reinforcing steel to be selected, passes the reinforcing steel through the gasket 64, and inserts the gasket 64 into the inner side of the four elastic clamping piece seats 63, so that the end of the gasket 64 is in contact with the spring 65. The connecting piece of the threaded sleeve 67 and the fixing sleeve 68 is aligned and sleeved on the outer side of the elastic clamping piece seat 63, so that the elastic pieces in the elastic clamping piece seat 63 are shrunk under the extrusion force of the fixing sleeve 68. Then, the inner side threads of the threaded sleeve 67 and the outer side threads of the four threaded blocks 66 are engaged with each other. After the threaded sleeve 67 is tightened, the four threaded blocks 66 will be synchronously radially displaced to the center position, driving the elastic pieces of the elastic clamping piece seat 63 to be gathered to the center, cooperating with the annular stress structure of the gasket 64, so that the clamping force is uniformly distributed along the circumferential direction of the reinforcing steel, avoiding local stress concentration to cause damage to the reinforcing steel. Moreover, through the cooperation of the inner side taper surface of the fixing sleeve 68 and the outer surface of the clamping piece of the elastic clamping piece seat 63, the clamping piece of the elastic clamping piece seat 63 can be ensured to have stable shrinkage, and the threaded connection between the threaded sleeve 67 and the threaded block 66 can be prevented from being loose under stress. Then, the operator sleeves the unlocking ring 69 on the outer side of the mounting shaft 61, so that the unlocking ring 69 can tightly contact the end of the threaded sleeve 67. Then, the standard part latch is passed through the hole of the mounting shaft 61 to limit the unlocking ring 69, so as to limit the axial movement of the unlocking ring 69 on the mounting shaft 61, and the butt joint ring 610 is connected to the tail thread of the mounting shaft 61 through the inner side thread.

[0047] This modular anchorage device only needs to replace gaskets 64 of different inner diameters for installation when reinforcing steels of different diameters are used. The gasket 64 not only isolates the direct contact between the reinforcing steel and the elastic clamping piece seat 63, thereby reducing the contact wear of the mechanical mechanism, but also forms a pre-tightening force adjustment buffer through cooperation with the spring 65, so that different diameter reinforcing steels can obtain consistent pre-tightening effect when clamped. At the same time, with the double restraint of the threaded sleeve 67 and the fixing sleeve 68, the reliable locking of the clamping state during the release of the reinforcing steel can be ensured, and the stress sensor 62 can also record the stress size according to the release process.

[0048] After the operator lays the reinforcing steel in the sleeper mold 4 and grouts, waits for the concrete pouring to be completed and reaches the specified strength, the operator controls the moving plate 3 to drive the sleeper mold 4 to move to the specified release stress area on the slide rail 1 through the control module (not marked in the figure). Then, the operator can drive the sliding seat 2 to gradually approach the sleeper mold 4 by sliding on the slide rail 1 through the control module (not marked in the figure).

[0049] The height of the sleeve 81 is adjusted to be close to the center height of the butt joint ring 610 on one side of the sleeper mold 4, and then the position of the butt joint ring 610 on one side of the sleeper mold 4 is measured by the industrial camera module 82. Then, the shooting data is uploaded to the control module, and after processing the data by the control module, the driving mechanism is adjusted after comparing the size of the sleeper mold 4 and the distance between the two butt joint rings 610 in the control module cloud. When the butt joint ring 610 is too small, the mounting plate 77 is lowered by the electric push rod 79 (in the initial state, the electric push rod 79 is in the lifting state), so that the mounting plate 77 drives the mounting seat 75 to move downward, thereby driving the corresponding gear two 74 to move downward, and the gear two 74 drives the corresponding connecting plate 73 on one side to rotate downward at the end of the gear one 72. After the two mounting seats 75 are pulled, the reciprocating screw rod 76 rotates inside the bracket of the mounting plate 77, converts the pulling force of the connecting plate 73 into the translation motion of the two mounting seats 75, and makes the two mounting seats 75 move towards each other under the limiting guidance of the auxiliary rod 78 outside the reciprocating screw rod 76, so that the two gear twos 74 drive the corresponding sleeves 81 to move towards each other.

[0050] By moving the sliding seat 2 to the direction of the butt joint ring 610 on one side of the sleeper mold 4, the sleeve 81 is connected to the butt joint ring 610, the gear one 72 is driven to rotate by the reduction motor 71, the two gear twos 74 are engaged with the gear one 72 to rotate, thereby driving the sleeve 81 to rotate and rotate the butt joint ring 610, so as to tension the prestressed steel bar and transfer the prestress to the concrete, so as to form a stable prestressed structure of the sleeper.

[0051] When the sleeve 81 is in abutment with the abutment ring 610, the contact rod 88 on one side of the abutment ring 610 is in abutment with the filling pipe 83, the contact rod 88 pushes the plug 84 inside the filling pipe 83, the U-shaped rod 85 is forced to slide inside the connecting channel of the filling pipe 83 and the oil box 87, the tail end of the U-shaped rod 85 pushes the piston plate 86 to slide inside the oil box 87, the piston plate 86 pushes the lubricating oil to the channel on one side of the oil box 87, the plug 84 no longer blocks the channel on one side of the oil box 87, the lubricating oil flows into the inside channel of the abutment ring 610 through the opening on one side of the contact rod 88 and the inside channel, and flows to the surface of the mounting shaft 61, spreads on the surface of the mounting shaft 61 and the connecting mechanism, forms an oil film cover layer, and under the action of centrifugal force generated by the rotation of the sleeve 81, the lubricating oil continuously penetrates, thereby uniformly covering the surface of the mounting shaft 61 and the inside contact surface position of the threaded sleeve 67 and the fixed sleeve 68, which can reduce the mechanical wear between the mounting shaft 61 and each connecting component, reduce the running resistance, and also can isolate the moisture and impurities in the air, effectively inhibit the oxidation and corrosion of the metal surface, and significantly improve the operation stability and service life of the entire mechanical system.
