[0002] The length of the beam string is nearly 100 meters, and it needs to be assembled in sections on the cradle on site. The butt welds are all first-level welds, which makes on-site welding difficult; the beam string is divided into multiple sections and assembled on the cradle, and the precision control of the external dimensions is difficult; the sliding unit is heavy, and to ensure synchronization during the sliding process, the construction height is dozens of meters, the amount of high-altitude work is large, many measures are taken for construction safety, and the available construction site is relatively limited. The construction process requires high coordination between the tower crane and the crane, and there are many instruments in the process, which may involve cross-operation with other types of construction.

DETAILED DESCRIPTION

[0025] The following is a detailed description of this design scheme with reference to the accompanying drawings.

[0026] A construction device for sliding and pushing a beam string is used to push a beam string structure 11, comprising: a hydraulic pump source system, a sensor detector, a computer synchronous control system, a sliding beam 1, a slide 2, a certain number of side block groups 3, a slide plate 4, an ear plate 1 5, a hydraulic cylinder 6, an ear plate 2 7 and a tightening block 8. The hydraulic pump source system, the sensor detector and the computer synchronous control system are electrically connected to the hydraulic cylinder 6 respectively. The specification of the sliding beam 1 is B (400-1000-400) × 700 × 20 × 35, and the material is Q355B. There are two slides 2, which are arranged parallel to the sliding beam 1 at a certain interval. The slide 2 structure plays the role of bearing, guiding and laterally limiting the horizontal displacement of the beam string structure 11 during the sliding process of the beam string structure 11. The side block groups 3 are arranged at a certain interval. Between the two slides 2, the side block is welded to the sliding beam 1, and one of the side blocks has a specification of 25×40×150mm (material Q235B), which plays a role in resisting the thrust and horizontal force of the sliding tensioned beam structure 11. There are two slides 4, which are symmetrically clamped on the two slides 2 respectively. The tensioned beam structure 11 is placed on the two slides 4, and the ear plate 5 is fixedly connected to the side wall of the tensioned beam structure 11 in the opposite direction of travel. One end of the hydraulic cylinder 6 is hinged to the ear plate 5 through a pin shaft, and its output end is hinged to the ear plate 2 7 through a pin shaft to transmit the horizontal sliding thrust. The ear plate thickness is t=20mm. The ear plate 2 7 is fixedly connected to one end of the tightening block 8 in the direction of travel. The two sides of the tightening block 8 are respectively clamped on the two slides 2, and the end opposite to the direction of travel is clamped with the side block group 3.

[0027] In some embodiments, the slide plate 4 is an inverted U-shaped structure, and the bottom sides are chamfered. During the horizontal sliding process, the occurrence of "rail jamming" and "rail gnawing" phenomena should be strictly prevented. The slide plate 4 uses a steel plate (material Q235B) with a specification of -35×120×L (L=500mm).

[0028] In some embodiments, the side block is welded to the sliding beam 1, and welding feet 9 are provided at the connection points on both sides. The side block weld adopts a double-sided fillet weld, and the height of the welding foot 9 is not less than 10 mm.

[0029] In some embodiments, the tightening block 8 is an inverted U-shaped structure, with a notch inclined upward on one side of its travel direction, and a positioning block 10 is also provided in the middle. The left and right inner walls of the tightening block 8 respectively abut against the outer walls of the two slides 2 and can slide relative to each other, and the two side walls of the positioning block 10 respectively abut against the inner walls of the two sides of the side block group 3 and can slide relative to each other.

[0030] In some embodiments, the length of the tightening block 8 is greater than the distance between two adjacent sets of side block groups 3 .

[0031] In some embodiments, a clamping plate 12 is provided at both ends of the top surface of the slide 4. When the beam-string structure 11 that needs to be pushed needs to be supported, the gap formed between the two clamping plates 12 is used to limit and fix the support 13 supporting the beam-string structure 11. The ear plate 5 is provided on the support 13. The clamping plate 12 is made of Q235B and is connected to the slide 4 through a fillet weld. The weld foot 9 has a size of 10 mm.

[0032] Example

[0033] The operator can observe the hydraulic jacking process and related data and (or) issue control instructions through the hydraulic synchronous computer control system human-machine interface in the central control room.

[0034] The jacking block 8 of the hydraulic jacking device has a one-way locking function. When the hydraulic cylinder 6 extends, the jacking block 8 works and automatically tightens the side of the slideway 2; when the hydraulic cylinder 6 retracts, the jacking block 8 does not work and moves in the same direction as the hydraulic cylinder 6.

[0035] Step 1: The hydraulic jacking device's jacking block 8 is installed on the slide 2, close to the side block group 3; the cylinder ear plate 5 of the hydraulic cylinder 6 is connected to the pushed tension string structure 11 through the pin shaft; the hydraulic jacking device's hydraulic cylinder 6 extends the cylinder, pushing the pushed tension string structure 11 to slide forward.

[0036] Step 2: The hydraulic cylinder 6 of the hydraulic pushing device continuously extends a stroke, pushing the pushed structure to slide forward a distance (a step distance).

[0037] Step 3: After one stroke of cylinder extension is completed, the pushed beam string structure 11 does not move; the hydraulic cylinder 6 of the hydraulic jacking device retracts the cylinder, so that the tightening block 8 is released from the slide 2 and the side block group 3, and moves forward with the hydraulic cylinder 6.

[0038] Step 4: After the hydraulic cylinder 6 has completed one stroke of cylinder retraction, it drags the tightening block 8 forward by one step. The pushing and sliding of one stroke is completed, and the next stroke sequence is executed from step 1.
