Double hole rail clamp for 43kg steel rails
GDGL-2 rail clip is a kind of double hole rail clamp, designed to fix 43kg heavy rails.
GDGL-2 double hole rail clamp is a two-hole pressure plate, which is a 43kg track fixture, 150*95*18mm long with a slope, and matching accessories include wedge-shaped backing plates, M-shaped backing plates, bolts, etc. The GDGL-2 track pressure plate complies with the 04G325 national standard (special size requirements can be customized according to the customer). Manufacturer’s phone: 18653422237. The GDGL-2 track pressure plate is used in industrial plants and missed trestle bridges with reinforced concrete crane beams or prestressed concrete crane beams.
Materials and requirements for GDGL-2 rail clamp:
1. Steel plate The splint and section steel adopt Q235 steel (No. 3 steel), and its technical conditions are in line with national standards.
2. Hexagon head bolts should meet the requirements of <GB/T5780-2000>, hexagon nuts should meet the requirements of <GB/T41-2000>, spring washers should meet the requirements of <GB/T93-1987>, and flat washers should meet the requirements of <GB/T93-1987>. GB/T95-2002> regulations.
3. The pressing plate adopts carbon steel castings (ZG230-450) or wrought cast iron (KTZ450-06), and its mechanical properties should meet the requirements of national standards.
4. The elastic backing plate adopts the rubber backing plate, the rubber tongue, and the rubber backing plate are made of oil-resistant rubber, and its performance should comply with GB/T5574-94 (industrial rubber standard)
GDGL-2 double hole rail clamp
General characteristics of GDGL-2 rail clamp:
1) It is used for the elastic fixed connection of steel rail concrete crane beam track. It has the performance of reducing the wear of the top of the rail, reducing the impact of the crane on the crane beam, reducing the wear of the crane wheel flange, and reducing the noise;
2) Because the elastic composite rubber pad is set between the track and the crane beam, it not only increases the friction between them, makes the rail-less easy to move, but also reduces or reduces the gap between the track and the crane beam along with the full length of the track The phenomenon of unevenness. Thereby improving the force of the pressure plate bolts.
3) The section of the elastic composite rubber backing plate is slightly convex in the middle so that the force is reasonable. The small rectangular convex strips on the backing plate are easy to deform, which not only makes the backing plate easy to contact with the track but also increases the elasticity of the backing plate. Played a shock absorption effect.
4) The rectangular groove of the elastic composite rubber backing plate is placed in the cross-sectional direction of the backing plate, which reduces the overall lateral deformation of the backing plate after being stressed, and reduces the damage to the rubber panel caused by the extrusion deformation. As it is equipped with treated steel plates, its structure is very reasonable. The performance remains good after 2 million fatigue performance tests. Therefore, the backing plate will not be damaged even after long-term use.
5) The pressure plate is fastened to the crane beam, it will not loosen and it is not easy to wear the crane beam. The symmetrically arranged pressing plates form a wedge-shaped structure in the section direction, thereby limiting the left and right displacement of the track.
6) The elliptical long hole designed on the main body of the pressure plate allows the pressure plate to be adjusted; the sloped hole is matched with the stop block to effectively prevent the pressure plate from moving and displacement after tightening. It provides convenience for the lateral adjustment of crane track installation or maintenance.
7) It is allowed to have a slight swing in the track during the operation of the crane
8) Used for welding long rails
