Detailed Implementation

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] Please see Figure 1 This utility model provides a high-efficiency and safe gantry rail system, including a first rectangular hollow steel section 1, a second rectangular hollow steel section 2 bolted to the upper end of the first rectangular hollow steel section 1, a third rectangular hollow steel section 3 bolted to the lower end of the first rectangular hollow steel section 1, the right side of the first rectangular hollow steel section 1 locked to the lower end of a fourth rectangular hollow steel section 4, and the upper end of the fourth rectangular hollow steel section 4 locked to the second rectangular hollow steel section 2, a first flat steel section 5 and a second flat steel section 6 bolted to the upper left side of the second rectangular hollow steel section 2, the lower ends of the first flat steel section 5 and the second flat steel section 6 locked to the first rectangular hollow steel section 1, a third flat steel section 7 installed at the lower right side of the first rectangular hollow steel section 1, and the lower end of the third flat steel section 7 locked to the bottom of the third rectangular hollow steel section 3, and a rail body 8 connected to the lower left side of the first rectangular hollow steel section 1.

[0026] The bolts used in the first rectangular hollow steel 1, the second rectangular hollow steel 2, and the third rectangular hollow steel 3 are of the same size, and the bolts are equipped with nuts, flat washers, and spring washers, thus forming a firm connection and locking structure.

[0027] Among them, the contact position between the main body of the track 8 and the first rectangular hollow steel 1 is coated with anti-bimetallic corrosion measures, thus achieving anti-corrosion treatment and improving service life.

[0028] Please see Figures 2-6 In this embodiment, the track body 8 is installed on the lower left side of the first rectangular hollow steel section 1. It should be noted that the track body 8 is made of 6061-T6 aluminum profile. Through bolts 9 are installed at both ends of one side of the track body 8, and these through bolts 9 are of type 2NOS M8 GR8.8. Vertical fixing bolts 10 are distributed on the four sides of the upper end of the track body 8, and these fixing bolts 10 are of type 4NOS GR8.8. M20 bolt type, the upper end of the fixing bolt 10 is inserted into the four sides of the positioning steel plate 11 to achieve positioning connection and locking movement, and the thickness of the positioning steel plate 11 is not less than 12mm. The positioning steel plate 11 and the first rectangular hollow steel 1 are welded with fillet welds 12 to improve the connection firmness. The outermost end of the first rectangular hollow steel 1 is welded with a first end plate 13. The upper ends of the first rectangular hollow steel 1 are welded with second end plates 14 on both sides, and there is a gap between the two second end plates 14, which are connected to the I-beam 15 on one side of the lower end of the first rectangular hollow steel 1.

[0029] Among them, the through bolt 9 is positioned at the two ends of the track body 8, which limits the movement of the gantry pulley to prevent it from slipping out of the track range.

[0030] Among them, the fillet weld 12 is welded to the connection between the first rectangular hollow steel 1 and the positioning steel plate 11, and the fillet weld 12 is extended to the connection between the second end plate 14 and the first rectangular hollow steel 1. The fillet weld thickness of the fillet weld 12 is not less than 5mm, that is, the connection between the lifting rail and the steel structure truss is firm, and the structural strength is enhanced.

[0031] The positioning steel plates 11 are evenly distributed at 3m intervals along the upper end of the main track body 8, and each positioning steel plate 11 is locked to the fixing bolts 10 on all four sides.

[0032] Among them, three sets of second end plates 14 are welded along the upper end of the first rectangular hollow steel 1, and the three sets of second end plates 14 are respectively bolted to the fourth rectangular hollow steel 4, the first flat steel 5 and the second flat steel 6.

[0033] The working principle is as follows:

[0034] First, the system uses the main track body 8 as the operating reference, and the gondola pulley moves back and forth along its track groove. The main track body 8 is locked with the positioning steel plate 11 by fixing bolts 10, and welded to the bottom of the first rectangular hollow steel 1 by fillet welds 12 to form the main connecting base. The first end plate 13 is used to seal the end to prevent deformation. At the same time, the through bolts 9 form a limit at the rail end to prevent the manned gondola from moving laterally out of the track range and overturning. Meanwhile, the manned gondola pulley slides in the groove of the main track body 8, and the manned gondola wire passes through the long opening between the two grooves of the main track body 8, which meets the special safety requirements of the gondola. At the same time, the first rectangular hollow steel 1, as the core force and tension transmission component, together with the second rectangular hollow steel 2, the third rectangular hollow steel 3 and the fourth rectangular hollow steel 4, forms a stable mechanical network. Combined with the I-beam 15, it forms an effective vertical and horizontal load-bearing channel, so that the upper load is reliably transmitted to the main structure, and the overall system load-bearing capacity and safety redundancy performance are improved.

[0035] Secondly, to ensure the stability of the manned gondola during operation, the superstructure adopts a multi-directional triangular support combination. The second rectangular hollow steel section 2 bears the tensile force and vertical pressure at the upper end of the rail. It is bolted to the first flat steel section 5 and the second flat steel section 6 to form a triangular diagonal bracing system on both sides. These first flat steel sections 5 and 6 are then bolted to the first rectangular hollow steel section 1, forming a three-sided stable force-bearing structure, effectively preventing lateral swaying and torque deviation caused by vibration during rail operation. The fourth rectangular hollow steel section 4 is diagonally supported at the right end of the first rectangular hollow steel section 1, thereby balancing the lateral load and further improving the torsional and tensile resistance of the connection nodes. The system uses high-strength bolts to achieve strong node connections, ensuring uniform force distribution when the gondola moves horizontally. The lower end of the system is supported by a third rectangular hollow steel section 3, which bears the main vertical load. Its upper end is connected to the first rectangular hollow steel section 1 by bolts. It further cooperates with the third flat steel section 7 to form a lower triangular stabilizing unit, realizing a closed loop of upper, middle and lower load distribution. This allows the load to be transmitted to the main building structure through multiple paths. In addition, the process requirements of the fillet weld 12 make the positioning steel plate 11 and the first rectangular hollow steel section 1 more firmly welded, achieving a rigid overall effect between the truss and the main track 8. This ensures structural stability during gondola operation and prevents deformation or fatigue failure.

[0036] Third, in terms of operational safety design, the through bolts 9 are arranged at both ends of the track body 8 to form physical limits, effectively preventing the gantry pulley from exceeding the usage area and causing derailment accidents; the fixing bolts 10 are vertically inserted into the positioning holes of the positioning steel plate 11 to create a precise positioning effect, avoiding track deviation caused by loosening of the connection after long-term use. In addition, the contact area between the first rectangular hollow steel 1 and the track body 8 is coated with anti-bimetallic corrosion material, effectively isolating the electrochemical corrosion between aluminum and steel, improving the applicability to outdoor high humidity environments, ensuring long-term reusability, and adopting standardized hole positions and bolt assembly methods to facilitate quick installation and disassembly, improve construction site efficiency, and reduce construction costs and environmental burden through reuse, achieving the beneficial effects of safety, efficiency and environmental protection.
