The steel ball sleeve 5 comprises 1 cylinder 501, a bottom plate 502 is fixedly connected to the outer side of the bottom of the cylinder 501, the bottom plate 502 is fixedly connected with the lower tray 1 through a high-strength bolt 503, and the steel ball sleeve can be well clamped and fixed with the steel ball 6.
And a reinforcing rib 504 is also connected between the side wall of the cylinder 501 and the bottom plate 502, so that the structural strength of the steel ball sleeve 5 is improved.
The stay bar 7 comprises a sleeve 701, and a screw 702 is sleeved in the sleeve 701 in a threaded manner, so that the extension length of the stay bar 7 can be conveniently adjusted.
T roof beam handling work flow: the T beam is hung on a T beam bracket 12 of a main gun and a subsidiary gun according to the normal condition, the T beam is tightly jacked by two side supporting rods 7, a steel rope (jack) is fixed from a T beam reinforcing hook 10 on one side and then wound from the T beam top to a T beam reinforcing hook 10 on the other side, a chain hoist is connected with the jack from a reinforcing hook on one side of the jack end, and the T beam loading reinforcement is completed by tightening the chain hoist. After the T beam is transported out from the beam field, the T beam is walked on a highway far away from one side of the bridge abutment as far as possible, after the auxiliary cannon is quickly approaching the bridge sideline extension line, steering is conducted to the bridge abutment, the main cannon walks straight line, when the auxiliary cannon is stopped when traveling to the tail end of the bridge machine, the front end of the T beam is lifted by the front crown block of the bridge machine, the main cannon continuously advances, and simultaneously the front crown block of the bridge machine is moved forward, the main cannon is slowly steered towards the bridge direction, when the T beam approaches to the truss at the other side of the bridge machine, the front crown block and the main cannon are moved backwards simultaneously, the main cannon is corrected, and the process is repeated until the main cannon and the bridge machine are on the same line, and the main cannon and the bridge machine are lifted according to a normal program.
Working principle: the beam plate longer than the road width is rotated by 90 degrees or more in a limited road width by adopting the principle of a push grinding method. Because the device adopts the ball 6 to support the upper turntable 2, the T beam can keep balance at any angle in the rotating process of the gun carriage, the gun carriage can not be turned over due to unbalanced stress, and meanwhile, the beam plate longer than the road degree can rotate by 90 degrees or more by utilizing the characteristic that the bridge crane crown block can move back and forth.
The application conditions are as follows: the bridge is a reinforced concrete prestressed T-shaped beam bridge with the width of 12m and 15T-shaped beams, wherein the bridge is a reinforced concrete prestressed T-shaped beam bridge with the width of 3X 30m in the Jiangkou county of the dangerous bridge reconstruction project in the copper core area of 2022 years. The beam-slab transportation that narrow needs the wide-angle steering of T roof beam of topography gorges is all suitable for.
Economic benefit: and after the beam plate is lifted and rotated 900 by adopting a large-sized automobile crane, the beam plate is lifted and rotated by using a gun carrier transportation bridge feeding bridge crane. Thus, the hoisting cost is high, the hoisting tonnage of the required crane is large, and the hoisting cost is exemplified by a 30mT beam: the weight of each side beam and each embedded part reaches 85 tons, if the maximum hanging distance of a gun carriage channel reserved on site is more than 20m, more than 400 tons of cranes are needed to finish the operation, the unit price of a 400 ton crane is 32000 yuan, 7 large-scale flat-bed trailers are needed to transport the balance weights in a field, and the transportation cost of the balance weights in the field is 10.8 ten thousand yuan when the balance weights are taken from Guiyang to Jiangkou as an example. Taking a copper rock bridge as an example: the total 15 pieces of 30mT beams of the bridge are hoisted for 7 days (including bridge machine through holes), the working cost of a crane is 7 multiplied by 32000= 224000 yuan, the hoisting mechanical cost (without bridge machine renting) is 332000 yuan when the working cost of the crane is added, and the hoisting mechanical cost is amortized to each piece of T beams to be 22133 yuan/piece. The whole refitting cost of the girder transporting vehicle is only 140400 yuan, and compared with the prior art, the girder transporting vehicle can save the engineering cost: 33200-140400= 191600 (yuan).
