Description

Technical Field

[0001] The utility model belongs to the field of mechanical production, in particular to large-scale components, and specifically is a state transport platform vehicle for transporting large-scale pipes. Background Art

[0002] When large pipe fittings are manufactured and processed, they often need to be transported to different workshops for different processing techniques. The transportation tools are generally rail-mounted non-powered transfer platform vehicles. This type of platform vehicle has a heavy load and strong inertia, but low friction, and can transport large pipe fittings effortlessly.

[0003] However, the current platform vehicles are limited by their structure, and their carrying tonnage can no longer meet the development needs of production and transportation. When carrying and lifting some overweight large pipes, the vehicle body may be bent or partially desoldered, resulting in the inability to disperse the force of the overall structure, causing serious deformation of the overall structure, and then derailment and damaging the ground. The maintenance frequency is high, and the efficiency of use is low, affecting normal production and transportation work. Utility Model Content

[0011] In the utility model, the frame also includes ribs, which are arranged on the other side of one beam relative to another beam, the ribs are perpendicular to the side of the beam and are evenly distributed, the outer ends of the ribs are connected to side beams, the height of the ribs is less than the beam, and rib plates are arranged at the lower part of the ribs, the rib plates are in the shape of right-angled triangle plates or right-angled trapezoidal plates, and the rib plates are respectively connected to fix the ribs and the beams or rail wheel frames.

[0017] The lower beam reinforcement plate provided at the lower part of the cross beam of the present application can further improve the stability of the connection between the cross beam and the main beam;

[0018] The track wheel frame structure of the present application can disperse the force of the track wheel supporting the frame, and the wheel frame reinforcement plate can strengthen the connection structure between the track wheel frame and the beam, thereby preventing the front and rear sets of wheel frames from being separated forward and backward respectively when bearing load, and effectively improving the overall stability of the frame;

[0025] A non-powered transfer platform vehicle is arranged on a ground track, comprising a vehicle frame 1, a vehicle plate and a track wheel 6, wherein the track wheel 6 cooperates with the ground track, the upper end surface of the vehicle frame 1 is flush and welded to the vehicle plate, the vehicle frame 1 comprises a main beam 2, a cross beam 3, a rib 5, a side beam 4 and a track wheel frame 7, Figure 1 and Figure 2 In the embodiment, two beams 2 are arranged in the front-to-back direction and are parallel to each other. A cross beam 3 is evenly arranged between the two beams 2. The two ends of the cross beam 3 are perpendicular to the beams 2 on both sides. Ribs 5 and side beams 4 are arranged outside the two beams 2. The side beams 4 are parallel to the beams 2. The ribs 5 are arranged between the beams 2 and the side beams 4. The two ends of the ribs 5 are respectively perpendicular to the beams 2 and the side beams 4. There are four sets of track wheel frames 7 and track wheels 6, which correspond to each other and are arranged at the front and rear ends of the two beams 2 respectively.

[0026] The cross beam 3 includes an upper beam and a lower beam of an integrated structure, the two ends of the upper beam are connected to the upper parts of the two side beams 2, the two ends of the lower beam are connected to the lower parts of the two side beams 2, the upper beam and the lower beam are of the same length, a lower beam reinforcement plate 8 is provided at the bottom of the beam 2, one side of the lower beam reinforcement plate 8 is connected to the inner edge of the bottom of the beam 2, and the other side of the lower beam reinforcement plate 8 is connected to the lower side surface of the lower beam.

[0027] The track wheel frame 7 includes two side plates arranged vertically in parallel, a track wheel 6 is arranged between the two side plates, an axle is passed through the center of the track wheel 6, and both ends of the axle are respectively connected to the two side plates, and an axle reinforcement plate 9 is arranged at the position where the side plate is connected to the axle, the two sides of the track wheel 6 are gap-matched with the two side plates, the front and rear ends of the two side plates are closed, and a crossbeam 3 is arranged between the two track wheel frames 7 symmetrically arranged on the left and right.

[0028] The width of the track wheel frame 7 is not less than the width of the beam 2, the height of the track wheel frame 7 is greater than the beam 2, and the lower part of the track wheel frame 7 that exceeds the beam 2 is provided with a wheel frame reinforcement plate 11. The wheel frame reinforcement plate 11 is in the shape of a right-angled trapezoidal plate, and a vertical edge of the wheel frame reinforcement plate 11 is fixedly connected to the track wheel frame 7, and the lower bottom edge of the wheel frame reinforcement plate 11 is fixedly connected to the beam 2.

[0029] The height of the rib 5 is smaller than the beam 2. A rib plate 10 is arranged at the lower part of the rib 5. The rib plate 10 is in the shape of a right-angled triangle plate.

When it is used to carry large pipe fittings, the large pipe fittings are hoisted to the middle of the vehicle plate of the platform vehicle, and wedge-shaped or block-shaped limiters are placed on the left and right sides of the large pipe fittings. The large pipe fittings can be moved and transported after they are stable and stationary.

The ground supports the vehicle frame 1 through the track wheel 6, and the track wheel frame 7 disperses the force to the pressure on the vehicle plate directly above it and the torsion of the track wheel frame 7 on the beam 2. The torsion from the track wheel frame 7 and the stress of the beam 2 itself form a pair of balancing forces. The beam 2 disperses the torsion to the pressure on the vehicle plate directly above it and the pulling force on the cross beam 3. The pulling force of the beam 2 on the cross beam 3 and the stress of the connecting structure between them form a pair of balancing forces, and the pulling forces of the two beams 2 on the cross beam 3 are equally neutralized. The lower beam reinforcement plate 8 and the wheel frame reinforcement plate 11 in the present invention are both arranged at the stress concentration point, which effectively increases the local stress to resist the deformation torque, so that the present invention has a higher overall structural stability.

[0031] In summary, combined with the above-mentioned structure and working process, it can be found that the utility model has novel conception, ingenious design, stable and strong overall structure, good force dispersion effect, strong carrying capacity, high transportation efficiency, low safety risk, and is not easy to damage.
