The utility model discloses a following technical scheme accomplishes: an overhead pulley for a portal frame comprises two connecting plates which are arranged at intervals and in opposite directions, and is characterized in that main bearing wheels are arranged at the upper parts of the two connecting plates, auxiliary bearing wheels in opposite directions are arranged at the lower parts of the two connecting plates, a connecting rod is arranged at the bottom of the two connecting plates, and a lifting ring is arranged on the connecting rod and connected with the portal frame.
The main bearing wheels are arranged on the top plate of the I-beam, the opposite auxiliary bearing wheels are respectively arranged on the wing plates on two sides of the bottom of the I-beam, so that the main bearing wheels and the opposite auxiliary bearing wheels move along the I-beam to form an overhead pulley, and the portal frame is driven to move through the hanging ring.
The two connecting plates are both vertical plates with rectangular upper parts and inverted trapezoidal lower parts.
The two main bearing wheels are arranged on the upper parts of the two connecting plates, and the two ends of the wheel shaft of each main bearing wheel respectively penetrate through corresponding through holes on the upper parts of the two connecting plates, extend outwards and are in threaded connection with nuts, so that the two main bearing wheels are fixed between the two connecting plates;
the number of the auxiliary bearing wheels at the lower parts of the two connecting plates is four, each connecting plate is provided with two auxiliary bearing wheels, and the wheel shaft of each auxiliary bearing wheel is in rolling connection with the corresponding bearing at the lower part of the connecting plate;
so as to improve the bearing capacity and the stability of the whole overhead tackle on the I-shaped beam 7, and ensure that the gantry frame connected with the hoisting ring can meet the requirements of dismounting and carrying while keeping the hoisting capacity of the gantry frame.
The distance between the main bearing wheel and the auxiliary bearing wheel is matched with the distance between the upper top plate and the lower wing plate of the I-beam.
The two ends of the connecting rod connected with the lifting ring respectively penetrate through the corresponding through holes at the bottoms of the two connecting plates and extend outwards to be in threaded connection with the nut, so that the connecting rod is fixed between the two connecting plates, and the lifting ring is fixed through the connecting rod.
The utility model has the advantages of the following and the effect: adopt above-mentioned scheme, make on the main bearing wheel arranges the roof on the I-beam in, the pterygoid lamina in I-beam bottom both sides is arranged respectively in to the supplementary bearing wheel in opposite directions, form overhead type coaster to make main bearing wheel, the supplementary bearing wheel in opposite directions remove along the I-beam, and then drive the portal frame through rings and remove, improve the utility model discloses bearing capacity on the I-beam makes the portal frame when keeping the hoisting capacity, can satisfy the requirement of the dismouting of being convenient for, transport. The utility model has the advantages of novel structure, convenient use, obvious effect, etc. The pulley is an ideal pulley.
