Description

Technical Field

[0001] The utility model belongs to the technical field of steel truss assembly construction, and particularly relates to a safety deviation correction device for steel truss assembly and towing. Background Art

[0002] During the towing construction of a steel truss, due to differences and variations in the frictional resistance between the steel beams on both sides of the steel truss and the slideway, changes in the height difference between the slideways, changes in the center of gravity of the beam, wind direction, temperature difference, etc., the steel truss will inevitably deviate laterally during the jacking movement.

[0003] In the prior art, a Chinese invention patent application with the application publication number CN113774813A discloses a traction deviation correction device for facilitating the installation of large-section steel truss box girders. A plurality of sliding carts are arranged at the bottom of the steel truss. During deviation correction, the sliding carts need to move and adjust along the direction perpendicular to the slide rail. The sliding carts move along the slide rail and cannot move along the direction perpendicular to the slide rail. During the adjustment process, the frictional force is large, the control difficulty is high, and it is easy to over-correct. The deviation correction hydraulic cylinder needs to be used in cooperation with a three-dimensional jack assembly to quickly correct the steel truss.

[0004] Therefore, it is necessary to design a safety deviation correction device for steel truss assembly and towing that reduces the frictional force between the steel truss and the slideway beam, reduces the adjustment control difficulty, and is not prone to over-correction to solve the current technical problems. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the utility model provides a safety deviation correction device for steel truss assembly and towing that reduces the frictional force between the steel truss and the slideway beam, reduces the adjustment control difficulty, and is not prone to over-correction.

[0006] The technical solution of the utility model is as follows: A safety deviation correction device for steel truss assembly and towing includes a load-sharing beam and a steel truss. A slideway beam is vertically arranged on the top of the load-sharing beam. A sliding shoe assembly is arranged above the slideway beam. The steel truss is arranged on the top of the sliding shoe assembly. A column is vertically and fixedly arranged on the top of the load-sharing beam. A jack corresponding to the side of the steel truss is vertically and fixedly arranged on one side of the column. A side sliding plate is fixedly arranged at one end of the jack close to the steel truss. The sliding shoe assembly is freely slidably connected to the top of the slideway beam.

[0007] The sliding shoe assembly has a sliding plate slidably arranged on the top of the slideway beam. An MGE plate is arranged at the bottom of the sliding plate. The steel truss is placed above the sliding plate.

[0008] Side limiting plates parallel to the slideway beam are arranged on both sides of the top of the sliding plate. A stiffening plate is arranged between the side of the side limiting plate facing away from the slideway beam and the bottom of the sliding plate.

[0009] A gap of 5-30 mm is reserved between the side limit plate and the slideway beam.

[0010] MGE board limit strips are arranged around the MGE board, and the MGE board limit strips are fixedly arranged at the bottom of the slide plate.

[0011] Steel cushion blocks are arranged on the top of the slide plate, and the steel truss is placed above the steel cushion blocks.

[0012] Rubber cushion blocks are arranged on the top of the steel cushion blocks, and the steel truss is placed above the rubber cushion blocks.

[0013] A stainless steel plate is fixedly arranged on the top of the slideway beam, and the MGE board slides freely on the top of the stainless steel plate.

[0014] The slideway beam is spliced by a number of H-shaped steels.

[0015] A connecting arm is arranged between the column and the slideway beam.

[0016] The beneficial effects of the utility model are as follows:

[0017] (1) In the utility model, during the towing process, a total station or a theodolite is used to intermittently observe and control the central axis of the steel truss in front of and behind the steel truss. The deviation of the central line of the steel truss is checked at any time. When it is found that the axis of the steel truss deviates, there is no need to stop the machine for deviation correction. A jack is used to gradually apply a certain horizontal force to the steel truss, so that the steel truss is offset back to the established axis and continue to be jacked.

[0018] (2) The sliding shoe assembly is freely slidably connected to the top of the slideway beam. When the steel truss is jacked by a jack, the sliding shoe assembly can slide along the direction perpendicular to the slideway beam. By setting the sliding shoe assembly, the friction between the steel truss and the slideway beam is reduced, the difficulty of adjustment and control is reduced, and it is not easy to over-correct the deviation.

[0019] (3) The end of the jack contacts the side of the steel truss through the side slide plate, which can reduce the friction on the side of the steel truss. Description of the Drawings

A side slide plate 7 is fixedly arranged at one end of the jack 6 close to the steel truss 1; the sliding shoe assembly 2 is freely slidably connected to the top of the slideway beam 4; in this embodiment, during the dragging process, a total station or a theodolite is used to intermittently observe in front of and behind the steel truss 1 to control the central axis of the steel truss 1, and the deviation amount of the center line of the steel truss 1 is checked at any time. When it is found that the axis of the steel truss 1 deviates, there is no need to stop the machine for deviation correction. The jack 6 is used to gradually apply a certain horizontal force to the steel truss 1 to make the steel truss 1 shift back to the established axis and continue to push; the sliding shoe assembly 2 is freely slidably connected to the top of the slideway beam 4. When the steel truss 1 is pushed by the jack 6, the sliding shoe assembly 2 can slide along the direction perpendicular to the slideway beam 4. By arranging the sliding shoe assembly 2, the friction between the steel truss 1 and the slideway beam 4 is reduced, the difficulty of adjustment and control is reduced, and it is not easy to over-correct; the end of the jack 7 contacts the side surface of the steel truss 1 through the side slide plate 7, which can reduce the friction on the side surface of the steel truss 1.

[0026] In some embodiments, as Figure 2As shown, the shoe assembly 2 has a skateboard 23 slidably arranged on the top of the slideway beam 4. An MGE board 24 is arranged at the bottom of the skateboard 23. The steel truss 1 is placed above the skateboard 23. The MGE board 24 has the characteristics of high compressive strength, wear resistance, low friction coefficient, large bearing capacity, strong shear and impact resistance, and easy connection and fixation with the skateboard 23.

[0027] In some embodiments, as Figure 3 shown, to reduce the lateral deviation of the skateboard 23 during the jacking process, side limit plates 231 parallel to the slideway beam 4 are arranged on both sides of the top of the skateboard 23. A stiffening plate 232 is arranged between the side of the side limit plate 231 facing away from the slideway beam 4 and the bottom of the skateboard 23. The strength of the side limit plate 231 can be improved through the stiffening plate 232.

[0028] In some embodiments, a gap of 5 - 30 mm is reserved between the side limit plate 231 and the slideway beam 4 to reserve a moving distance for deviation correction.

[0029] In some embodiments, MGE board limit strips 241 are arranged around the MGE board 24, and the MGE board limit strips 241 are fixedly arranged at the bottom of the skateboard 23.

[0030] In some embodiments, steel cushion blocks 22 are arranged on the top of the skateboard 23. The steel truss 1 is placed above the steel cushion blocks 22. According to the height requirements of different shoe assemblies 2, steel cushion blocks 22 with different heights can be adopted, and the steel cushion blocks 22 are fixed to the top of the skateboard 23 by welding.

[0031] In some embodiments, rubber cushion blocks 21 are arranged on the top of the steel cushion blocks 22. The steel truss 1 is placed above the rubber cushion blocks 21. When the steel truss 1 is placed above the steel cushion blocks 22, the rubber cushion blocks 21 play a certain buffering role for the steel truss 1.

[0032] In some embodiments, a stainless steel plate 41 is fixedly arranged on the top of the slideway beam 4, and the MGE board 24 slides freely on the top of the stainless steel plate 41.
