[0024] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0025] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 3 As shown, the utility model provides a correctable sliding system for dragging a steel beam. By designing a sliding system with self-correction, a special slide 200 with correction is set on the surface of a common slide 100, and the slide 200 with correction is divided into an upper and lower part. The upper slide 202 can realize horizontal left and right movement on the lower slide 201 under the action of the horizontal correction jack 300. When correction is needed, the horizontal position of the upper slide 202 can be adjusted at any time to drive the steel beam to move horizontally. The lower slide 201 is connected to the horizontal drag jack 500 and the steel strand 700 set in front of the slide 100. The lower slide 201 is pulled by the horizontal drag jack 500 to drive the steel beam to slide longitudinally. A vertical jack 400 is set at the head of the slide 100 to adjust the vertical height of the steel beam.

[0027] Specifically, by setting a slide with a correction function, a lateral correction, a vertical jack 400 and a horizontal drag jack 500 on the slide 100, the three-way movement of the steel beam under the support of the slide is realized. Among them, the steel beam is placed on the top surface of the slide with correction 200, and the slide 100 is fixed with temporary piers and other fixed supports. By laying a stainless steel plate 102 on the slide 100, a polytetrafluoroethylene slide plate is fixed on the bottom surface of the slide to form a longitudinal sliding surface 206, and the horizontal drag jack 500 drags the slide to make the stainless steel plate 102 and the polytetrafluoroethylene slide plate slide relative to each other, so as to realize the longitudinal movement of the steel beam. By setting a lateral limit device and a pull-back lateral roller 207 on both sides of the lower slide 201, the lateral limit of the slide when sliding back and forth is realized. By setting two layers of slides on the slide with correction 200, and setting a lateral sliding surface 205 of the stainless steel plate 102 and the polytetrafluoroethylene slide plate between the two layers, the lateral relative movement between the upper and lower slides is realized, so that the steel beam can realize lateral correction. By setting a reaction seat in front of the slideway 100 and installing a horizontal towing jack 500, the longitudinal towing of the slide is realized. The vertical height of the steel beam is adjusted by the vertical jack 400 set in front of the slideway 100. The slide is quickly returned by the pull-back winch 600 set at the tail of the slideway 100. The horizontal forward movement of the slide and the steel beam is realized by the steel strand 700 between the slide and the horizontal towing jack 500.

[0028] The sliding system of the present application mainly includes: a slideway 100, a sliding seat with correction 200, a transverse correction jack 300, a vertical jack 400, a horizontal towing jack 500, a sliding seat pull-back winch 600 and a towing connection steel strand 700.

[0029] The slideway 100 mainly includes: a slideway beam 101 and a stainless steel plate 102. The slideway beam 101 and the stainless steel plate 102 are welded, and the surface of the stainless steel plate 102 is flat to ensure smooth sliding.

[0030] The belt correction slide 200 mainly includes: a lower slide 201, an upper slide 202, a transverse correction block 203, a longitudinal sliding block 204, a transverse sliding surface 205, a longitudinal sliding surface 206, a pull-back lateral roller 207 and a connecting hole 208 for the steel strand 700. The lower slide 201 is arranged above the slide 100 and slides back and forth longitudinally along the slide 100. The upper slide 202 is arranged on the lower slide 201, and a steel beam is placed above the upper slide 202. The transverse correction jack 300 is used to move transversely between the upper and lower slides 201 to ensure the transverse correction of the steel beam. The transverse correction block 203 is arranged between the upper and lower slides 201, and is a limiting device when the steel beam is corrected. The longitudinal sliding block 204 is used to limit the slide when the steel beam slides, ensuring that the steel beam moves along the slide 100. Grease is applied between the transverse sliding surface 205 and the longitudinal sliding surface 206 to ensure smooth sliding of the sliding surface. The pull-back lateral roller 207 is a roller set on the side of the slide seat and the slideway 100 when the slide seat is pulled back to ensure smooth pull-back. The steel strand 700 connection hole 208 is a device for connecting the steel strand 700 to the slide seat through the anchor head after passing through the slide seat.

[0031] The lateral deviation-correcting jack 300, the vertical jack 400 and the horizontal dragging jack 500 are respectively tool-type hydraulic jack structures, which respectively realize the three actions of the steel beam through the action and control system of the hydraulic equipment.

[0032] The pull-back winch 600 is mainly used to pull the slide back quickly. The dragging connecting steel strand 700 is used to connect the slide and the horizontal drag jack 500, so as to realize the forward movement of the slide and drive the steel beam to move.

[0033] The construction method of steel beam dragging using the system of the present application comprises the following steps:

[0034] Step 1: If Figure 4 As shown, the vertical jack 400 lifts up the steel beam as a whole and then lowers it, so that the steel beam is placed on the slide seat for support and force, and the gap between the vertical jack 400 and the bottom plate of the steel beam is greater than 100 mm.

[0035] Step 2: If Figure 5 As shown, the slide is dragged forward by the horizontal drag jack 500 and the steel strand 700 in front. During the sliding process and when the slide is in place, the slide's own deviation correction function can be used to adjust the horizontal deviation of the steel beam and drag the entire steel beam forward by a segment of 14m.

[0036] Step 3: If Figure 6 As shown, after a segment is pushed up, the steel beam is lifted up as a whole by a vertical jack 400. The dragging slide is not subjected to stress, but is subjected to stress by the vertical jack 400. The gap between the supporting slide and the bottom of the steel beam is greater than 80 mm.

[0037] Step 4: Figure 7 As shown, the pull-back winch 600 provided at the tail is used to pull the slide back as a whole and restore it to the starting position, and then the vertical jack 400 lowers the steel beam onto the slide to bear the force, preparing for the next jacking cycle.
