Whether it is in infrastructure construction fields such as ports, docks, bridges, and tunnels, or in industrial production fields such as machinery manufacturing and automobile manufacturing, gantry cranes can be used to complete the lifting and handling of various heavy objects.

[0003] However, in the existing gantry crane track beam support structure, during the open cut method construction of the underpass tunnel in the municipal engineering, in order to facilitate the material transportation, formwork disassembly and transfer during the construction process.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1-5, an embodiment provided by the utility model: a support structure for a gantry crane track beam, including a lower cover plate 1. In the middle position of the upper side wall of the lower cover plate 1, an I-beam 2 is installed. The I-beam 2 includes a joint reinforcement plate 3. In the middle position of the inner side wall of the joint reinforcement plate 3 and on both sides near the middle position of the inner side wall, a number of I-beam webs 5 are installed. On both side walls and in the middle position of the number of I-beam webs 5, embedded rib plates 4 are installed. The number of embedded rib plates 4 are distributed in a rectangular array. In the middle position of the upper side wall of the joint reinforcement plate 3, a reinforcement steel plate 8 is installed. The application of this gantry crane track beam support structure effectively solves the problem of the gantry crane walking across the pump house, provides great convenience for the hoisting of materials on site, ensures the safety of material hoisting at the pump house part, and saves construction costs.

[0032] On the upper side wall of the reinforcement steel plate 8, near the middle position, a track lower backing plate 7 is installed. In the middle position of the upper side wall of the track lower backing plate 7, a traveling wheel 6 is installed. The traveling wheel 6 is a schematic diagram of the gantry crane traveling mechanism. Through the cooperation between the track lower backing plate 7 and the limit plate 11 and the channel steel, the traveling wheel 6 is limited. On the upper side wall of the reinforcement steel plate 8, in the middle position near the other side, an upper cover plate 9 is installed. The reinforcement steel plate 8 is welded to the I-beam, ensuring the overall force stability of the track beam structure. The upper cover plate 9 is made of a rigid material and is used to cooperate with the upper side wall of the reinforcement steel plate 8 near the other side to adapt to gantry cranes of different models and weights.

[0033] On the upper side wall of the upper cover plate 9, in the middle position near the other side, a partition plate 10 is installed. On the upper side wall of the upper cover plate 9, in the middle position near one side, a limit plate 11 is installed. The partition plate 10 and the limit plate 11 are mirror-image and oppositely distributed. The partition plate 10 and the limit plate 11 are used for the limit during the gantry crane walking. At the end of the I-beam 2, a triple-plate 14 is welded. One end of the connecting steel plate 13 is welded to the surface of the triple-plate 14. The inner side wall of the connecting steel plate 13 is welded to the outer side wall of the H-shaped steel flange of the SMW method pile H-shaped steel 12, forming a support system for the gantry crane track beam across the pump house section, ensuring that the gantry crane track beam can smoothly pass through the deep and large foundation pit at the pump house position.

[0034] A number of I-beam webs 5, a number of embedded rib plates 4, the reinforcement steel plate 8 and the lower cover plate 1 are all made of rigid materials. Steel materials have high strength, good impact resistance: The strength of steel is high and it is widely used in various projects. Its impact resistance is strong and it can resist external impact forces. It has strong corrosion resistance: The corrosion resistance of steel is good and it can be used for a long time in harsh environments. It has good plasticity: Steel can be shaped into various shapes through various processing methods, greatly broadening the scope of use. Each group of I-beam webs 5 and each group of embedded rib plates 4 are connected to form a triple-plate 14, and the triple-plate 14 is welded and temporarily fixed.

[0035] Working principle: Lay out lines on the bearing girder according to the gauge of the crane, pop out the center line of the track, and then pop out the bottom edge line of the track according to the bottom width of the track. Taking the track line on the conductive side as the benchmark, use a steel tape measure and a spring scale to determine the center line of the other side of the track according to the gauge, pop out the center line of the track and the installation lines at both ends, hoist the three-piece section steel and make temporary fixation. Adjust the elevation: Add the required shims according to the measured elevation. After the elevation is adjusted and in place, align, position, and fasten the track. Install and adjust the track of the gantry crane at the joint of the track spanning the pump house and the crown beams at both ends by pulling a wire. After the adjustment is in place, use connecting steel plates to fix and weld the section steel of the track beam spanning the pump house and the diaphragm wall pile, so that the track beam spanning the pump house and the diaphragm wall pile are connected into a whole. When the gantry crane at the pump house spanning the pump house is in operation, it is in a simply supported stress state. Through calculation, the deflection is 23.7 mm under the condition of the maximum load of 200 KN on one side. In order to make the traveling of the crane smooth, a 25-mm camber is reserved during the processing of the steel beam. Three lateral stabilizer bars are welded to the web of the steel beam at the center position of the steel beam to prevent the steel beam from losing stability due to the impact and vibration when the crane trolley moves. When conducting the re-inspection of the track, the track foundation is laid as required, and the horizontal distance between the center line of the track and the foundation is determined. The track is re-inspected and accepted by the on-site operation supervisor, technician, and project quality inspection department at three levels. Before installation, the actual situation of the track should be measured, and the best position should be selected as the installation reference position of the gantry crane. Tools used: level, steel tape measure, spring scale, feeler gauge. The specific inspection requirements are as follows: The gap between the track joints is not more than 2 mm, the height difference and lateral misalignment of the track joints are not more than 1 mm, the longitudinal inclination of the track top surface relative to its designed position is not more than 3 / 1000, the height difference within the whole stroke is not more than 10 mm, the elevation of the reference point on the track top surface allows a tolerance of ±10 mm relative to the designed elevation, and the elevation difference between the two parallel tracks in the same section is not more than 10 mm.
