Description
Technical Field
The utility model relates to a hoisting equipment technical field, in particular to press from both sides rail utensils wedge clamp clamping block's positioning mechanism.
Background
The existing rail clamping devices are various in types, wherein wedge-shaped clamping block type rail clamping devices are increasingly paid more attention and are rapidly developed. The rail type clamping rail device with wedge-shaped clamping blocks relates to various rail types: the rail clamp comprises standard series rails such as light rails and heavy rails, section steel rails such as channel steel, I-steel and H-shaped steel, even linear and plate rails such as steel strands, steel belts and steel plates, and certain parts of existing engineering structural members are used as rails, but no matter what kind of rails, the rail clamp has the characteristic that two symmetrical rail surfaces are used as clamping working surfaces of the rail clamp.
The rail clamping device uses the wedge-shaped clamping block, regardless of the shape and the size, and has the characteristic that the basic form of the wedge-shaped clamping block has a working tooth surface for clamping a rail surface and a wedge surface matched with a sliding wedge surface of a rail clamping device box body.
In an ideal state, in any working stage of the rail clamping device, the wedge surface of the wedge-shaped clamping block is always attached to the sliding wedge surface of the rail clamping device, the two wedge-shaped clamping blocks which are paired are in a symmetrical state with the rail as the center, the two clamping blocks are synchronously and symmetrically clamped in the clamping stage to obtain the maximum clamping force, the two clamping blocks are balanced in stress, and the two clamping blocks are withdrawn after being synchronously separated from the rail surface in the opening stage to obtain the optimal opening distance, so that the rail clamping device can be easily displaced without damaging the tooth surface of the clamping block and the working surface of the rail.
The actual situation is not the same, because the existing rail clamping devices are not provided with clamping block positioning mechanisms, wedge surfaces of the clamping blocks cannot be attached to sliding wedge surfaces of the box body during working, and when the clamping blocks are opened, one end of each clamping block can stretch downwards due to dead weight or other factors, and even the whole clamping block can be hung on a rail surface. When the rail clamping device is displaced, even if the clamping block is loosened, the working tooth surface of the clamping block stretched on the rail surface still clings to the rail surface, the working tooth surface of the clamping block and the rail surface are rubbed with each other to cause mutual abrasion along with the displacement of the rail clamping device on the rail surface, more seriously, the clamping block cannot be completely separated from an occluded state, the tooth point of the clamping block is still embedded in the rail surface, and along with the displacement of the rail clamping device, the rail surface forms shearing to the tooth point of the clamping block, so that the tooth point is extremely easy to shear, and the clamping block is directly scrapped. No matter wear each other or the prong is cut off, will shorten the life who presss from both sides tight piece greatly, increase the consumption that presss from both sides tight piece, strain the rail face, increase later stage rail face repair work load and influence track structural strength even threatens the engineering quality.
Further, as described above, due to the severe friction between the clamping blocks and the rail surface, the resistance when the rail clamping device is shifted will be increased, the position where the clamping blocks stay after the rail clamping device is shifted will also be affected, the paired clamping blocks are difficult to be in a symmetrical state, when the rail clamping device is clamped next step, the two clamping blocks will appear in tandem, except that the clamping force is affected, the stress of the increased clamping blocks is uneven, and the damage of the clamping blocks is easily caused, the center of the whole rail clamping device will also be shifted, the direction of the reverse thrust provided by the rail clamping device will also be changed accordingly, and the working effect of the rail clamping device will be seriously affected.
As mentioned above, the back thrust of the rail clamping device during clamping can be greatly reduced due to the abrasion of the tooth surface of the clamping block, the construction quality is seriously influenced, and meanwhile, the clamping block needs to be frequently replaced along with the increase or scrapping of the abrasion of the clamping block, so that the working efficiency is greatly influenced, and the engineering progress is influenced.
The on-site condition of the rail clamping device during working is extremely poor, under the actual working condition, the rail clamping device and the rail are difficult to be in an ideal centering state, the whole rail clamping device can float when being clamped and opened, and the clamping blocks in the rail clamping device are difficult to be in a symmetrical and synchronous state when being clamped every time, so that the clamping effect and the construction quality under the actual working condition cannot be ensured at all.
As described above, it is very important and necessary to precisely position the wedge-shaped clamping block in the rail clamping device to improve the clamping effect of the rail clamping device, prolong the service life of the clamping block, and reduce the damage to the rail surface.
