I. Prerequisites for product installation

Rail clips with adjustable by rail clips can overcome the past traditional rail clips in use in fault, traditional platen in use is often directly and rail pressure of the rail steel on steel, after installation can't guarantee the platen and rail have reliable contact, some of the pressure plate after installation can't to adjust the horizontal direction, This is easy to wear after the normal load or thermal expansion and contraction caused by longitudinal movement of the track, resulting in loose plate bolts, plate rotation, resulting in track surface wear and gnawing rail, serious rail breakage, which will also affect the wear of the host wheel and drive mechanism damage. When the adjustable combined rail platen is used, the rail can be fixed in the horizontal direction and the rail position can be adjusted horizontally. For example, the QU80 platen allows the lateral adjustment of the distance to the rail to be 15mm. QU120 platens allow lateral adjustment of the spacing to 20mm on the track. And has the self-locking function, can reliably fix the track, prevent the track in the big wheel pressure when the offset. An elastic force is used to fix the track in the vertical direction. That is, the hot rubber tongue on the track pressure head is made of wear-resistant, oil-resistant, high-temperature resistant and corrosion-resistant synthetic rubber.

1. Installation of rail pressing device shall be carried out after the steel beam of lifting surface is adjusted; Rail pressure device

2. The steel beam of the crane shall meet the requirements of the Code for Construction and Acceptance of Steel Structure Engineering (GBJ205-83) and the current code for steel structure;

3, rail pressure device should be installed;

4. Before rail pressure installation, the crane beam surface painting is finished and in line with the current requirements;

5. Before the rail pressure device is installed, the track joint should be connected completely. The track joint and lateral bending deviation conform to the provisions of the Steel Structure Engineering and Acceptance Code (GBJ205-83).

6. The welding between the bottom control panel and the steel hanging beam shall meet the design requirements.

Two, installation sequence and key points

A, welding fixed base, can use the fixed base, the surface of the three grooving and rail pressure device ** position positioning, the position of the crane beam ** line allowable deviation is ±1.0mm;

B. Put the T-bolt into place and move it toward the rail;

C. Place the wedge adjusting plate and make the slotted side face up;

D. Install rail platens, washers, spring washers and nuts successively;

E. Move the wedge adjusting plate to adjust the rail press in a position perpendicular to the rail direction. Tighten the nut after the rail press plate is tightly pressed with the rail lower flange;

F. The influence of welding fixed plate on the disturbance variation of crane beam should be considered during design or construction.
