Description

A tire crane track welding rail pressing tooling

technical field

The utility model relates to the field of cranes, in particular to a rail welding tool for tire crane rails.

Background technique

With the growth of port container throughput, the improvement of loading and unloading efficiency and economic benefit requirements, and the development of modern science and technology, tire cranes have begun to play an increasingly important role.

Most of the trolley rails of tire cranes are fixed by welding to the girder. Recently, welding cracks on the trolley rails have frequently appeared in major ports around the world. After research, the residual stress caused by unreasonable welding methods has been removed. The gap between the trolley track and the girder panel is also a potential factor for cracks, which directly affects the fatigue life of the welded track; because the backing plate needs to be welded to the bottom surface of the track before the track and the girder panel are welded, the backing plate is deformed, and then resulting in gaps.

In order to reduce the gap between the trolley track and the girder panel, it is necessary to design a reasonable tooling to restrain it.

Contents of the invention

The problem to be solved by this utility model is to provide a tire crane track welding rail pressing tool to reduce the gap between the trolley track and the girder panel.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a tire crane track welding rail clamping tool, and its innovative point is that the rail clamping tool includes a beam, two legs supporting the two ends of the beam, located on the beam There are two pressing mechanisms on the top; the lower end of the leg is fixed on the cast iron platform by bolts, and the upper end is provided with ear plates, which are fixed with the two ends of the beam by bolts; the pressing mechanism includes a slider, which passes through the slider vertically The screw, the runner fixedly connected to the top of the screw and the pressure head located at the bottom of the screw, the inner side of the slider and the screw contact are provided with threads, when the runner is rotated, the screw can move up and down, the bottom of the pressure head has A groove penetrating along its long axis, the groove can be fitted with the top of the track, the top of the indenter is movably connected with the screw, and the indenter will not follow the rotation of the screw; the upper end of the beam is provided with a The protrusion extending in the direction of the beam, the upper end of the slider near the cross beam is provided with a groove that can fit the protrusion, and the bottom end of the side near the cross beam is provided with a stopper in contact with the lower end of the cross beam, so that the slider and the cross beam It is articulated and can translate along the long axis of the beam.

Further, a handle for vertical auxiliary rotation is provided on the rotating wheel.

Further, the protrusion on the beam is discontinuous, and the slider can be installed on the beam from the break of the protrusion.

Beneficial effects of the utility model: 1. The rail is tightly attached to the girder panel by using the rail pressing tool, which eliminates the gap and reduces the factors causing cracks; 2. Since the distance between the two pressing mechanisms can be adjusted, the rail pressing tool It is suitable for various types of tracks and has a wide range of applications.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Fig. 1 is a schematic diagram of a tire crane track welding rail pressing tool of the present invention.

Fig. 2 is the A-A view of Fig. 1 .

Fig. 3 is a B-B view of Fig. 2 .

Detailed ways

As can be seen from the schematic diagrams shown in Figure 1, Figure 2 and Figure 3, the utility model discloses a tire crane track welding rail clamping tool, the rail clamping tool 2 includes a beam 3, and two legs 4 supporting the two ends of the beam 3 , Two pressing mechanisms 5 located on the beam 3 .

The lower ends of the supporting legs 4 on both sides are fixed on the cast iron platform 1 by bolts, the upper ends of the supporting legs 4 are provided with ear plates, and the two ends of the supporting legs 4 and the beam 3 are fixed by bolts.

As can be seen from the schematic diagram shown in Figure 3, the pressing mechanism 5 includes a slide block 8, a screw rod 7 passing through the slide block 8 vertically, a runner 6 fixedly connected to the top end of the screw rod 7, and a pressure head 9 positioned at the bottom end of the screw rod 7 The inboard of slide block 8 is provided with screw thread at contact with screw rod 7, when rotating runner 6, screw rod 7 can move up and down in the vertical direction, and the bottom surface of pressure head 9 has a groove through along its long axis direction, The groove can just fit with the top of the track, and the top of the pressure head 9 is flexibly connected with the screw rod, so that when the rotating wheel 6 is rotated, the pressure head 9 will not follow the rotation of the screw rod 7; The protrusion 10 extending in the direction, the slider 8 of the pressing mechanism 5 is provided with a groove that can just fit the protrusion at the upper end of the side near the cross beam, and a groove that is in contact with the lower end surface of the cross beam 3 is provided at the bottom end of the side near the cross beam 3. The stopper makes the slider 8 movably connected with the crossbeam 3 and can translate along the long axis direction of the crossbeam 3 .

When in use, the upper panel of the girder is first spliced and hoisted on the platform 1, fixed, and then the track is assembled, and a plurality of rail clamping fixtures 2 are installed at a certain distance along the track direction, and the legs 4 of the rail clamping fixture 2 are fixed on the platform 1 with bolts. On the platform 1, adjust the position of the slider 8 on the pressing mechanism 5 to align with the track, rotate the runner 6, clamp the track until there is no gap between the track and the girder panel, and weld.
