Abstract
An overhead traveling crane vertical loading board for difficult drop-off, belonging to overhead traveling crane lifting utensil technical field, coming off for preventing vertical loading board when lifting weight.Its technical scheme is: it comprises vertical loading board, snap ring, puller bolt, snap ring is metal ring, the diameter of bore of snap ring and the external diameter of vertical loading board match, snap ring circumferentially hold out against screw, hold out against the axial circle diameter along snap ring of screw, hold out against the center that screw is positioned at snap ring wall width, puller bolt with hold out against screw and match, two snap rings are set in the two ends of vertical loading board.The utility model in hoisting process vertical loading board once run-off the straight, owing to there being the stop of snap ring, vertical loading board can not come off from the suspension ring of hanging belt or steel rope, also can not slippage from the suspension ring hole of weight with holes, avoid weight from free falling in midair, eliminate in lifting operation the potential safety hazard using vertical loading board to exist.The utility model structure is simple, esy to use, safe and reliable, has the value promoted the use of.
Description
Technical field
The vertical loading board that the utility model uses when relating to a kind of overhead traveling crane lifting weight, belongs to overhead traveling crane lifting utensil technical field.
Background technology
When overhead traveling crane carries out lifting operation, overhead traveling crane connects weight lifting indirectly by suspension rod sometimes.Conveniently, save trouble, overhead traveling crane and suspension rod, between suspension rod with weight often through the simplest hanging belt or steel rope etc. carry out binding be connected after hoisting heavy, start to the weight liftoff stage in overhead traveling crane lifting, due to weight crank, the reason such as to rock, cause suspension rod run-off the straight sometimes and come off, especially when suspension rod be horizontally through weight with holes directly lift by crane time, the easier run-off the straight of suspension rod comes off, thus cause weight from free falling in midair, bring very big hidden danger to production and safety.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of overhead traveling crane vertical loading board of difficult drop-off, this vertical loading board can effectively prevent from overhead traveling crane from using vertical loading board indirectly to lift in weight process vertical loading board occurs tilting to come off, and eliminates in lifting operation the potential safety hazard existed thus.
The technical scheme solved the problems of the technologies described above is:
A kind of overhead traveling crane vertical loading board of difficult drop-off, it comprises vertical loading board, snap ring, puller bolt, snap ring is metal ring, the diameter of bore of snap ring and the external diameter of vertical loading board match, and have gap between snap ring endoporus and the outer wall of vertical loading board, snap ring circumferentially hold out against screw, hold out against the axial circle diameter along snap ring of screw, hold out against the center that screw is positioned at snap ring wall width, puller bolt with hold out against screw and match, two snap rings are set in the two ends of vertical loading board.
The overhead traveling crane vertical loading board of above-mentioned difficult drop-off, the bar wall at the two ends of described vertical loading board holds out against plane respectively, hold out against the longitudinal axis of plane and vertical loading board, hold out against plane and be positioned at the position that vertical loading board installs snap ring, hold out against plane relative with the puller bolt front end on snap ring.
The overhead traveling crane vertical loading board of above-mentioned difficult drop-off, the diameter of bore of described snap ring is greater than the external diameter 2-3mm of vertical loading board, and the wall thickness of snap ring is 10-20mm, and the width of snap ring is 30-50mm, and the diameter holding out against screw is 10-15mm, and the length of puller bolt is greater than 60mm.
The beneficial effects of the utility model are:
Snap ring of the present utility model is set in the two ends of vertical loading board, snap ring is fixedly connected with vertical loading board by puller bolt, vertical loading board in hoisting process is once run-off the straight, owing to there being the stop of snap ring, vertical loading board can not come off from the suspension ring of hanging belt or steel rope, also can not slippage from the suspension ring hole of weight with holes, avoid weight from free falling in midair, eliminate in lifting operation the potential safety hazard using vertical loading board to exist.The utility model structure is simple, esy to use, safe and reliable, do not change original lifting mode and vertical loading board structure simultaneously, has the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the lateral plan of Fig. 1;
Fig. 3 is using state schematic diagram of the present utility model.
In figure, mark is as follows: vertical loading board 1, snap ring 2, puller bolt 3, hold out against plane 4, electrode 5.
Detailed description of the invention
The utility model comprises vertical loading board 1, snap ring 2, puller bolt 3.
Show in figure, snap ring 2 is circular metal ring, and the diameter of bore of snap ring 2 is greater than the external diameter 2-3mm of vertical loading board 1, and the wall thickness of snap ring 2 is 10-20mm, and the width of snap ring 2 is 30-50mm, and two snap rings 2 are set in the two ends of vertical loading board 1.
Show in figure, the outer circumferential walls of snap ring 2 holds out against screw, hold out against the axial circle diameter along snap ring 2 of screw, hold out against the center that screw is positioned at snap ring wall width, puller bolt 3 with hold out against screw and match, the diameter holding out against screw is 10-15mm, and the length of puller bolt 3 is greater than 60mm.Puller bolt 3 withstands on the sidewall of vertical loading board 1 through holding out against screw, snap ring 2 and vertical loading board 1 is locked firmly, snap ring 2 can not be slided along vertical loading board 1.
Show in figure, the bar wall at the two ends of vertical loading board 1 holds out against plane 4 respectively, hold out against the longitudinal axis of plane 4 and vertical loading board 1, hold out against plane 4 and be positioned at the position that vertical loading board 1 installs snap ring 2, puller bolt 3 withstands on and holds out against in plane 4.The effect holding out against plane 4 is that puller bolt 3 is pushed up in the plane, instead of withstands on the circular arc outer wall of vertical loading board 1, makes to hold out against more firm.
An embodiment of the present utility model is as follows:
Lifting snap ring 2 material be 45# steel, internal diameter 30mm, wall thickness 12.5mm, width is 30mm, snap ring 2 Width has a diameter be 10mm hold out against screw.
The material of puller bolt 3 is 45# steel, and length is 65mm, and external thread diameter is 10mm, and the nut of puller bolt 3 is hexagon, thickness 8mm, and width is 19mm.
Vertical loading board 1 bar wall two ends point-blank process and hold out against plane 4, and the width holding out against plane of the present embodiment is 12mm, and length is 40mm.
Fig. 3 shows, and the utility model uses vertical loading board 1 to lift by crane electroslag remelting electrode 5, installs snap ring 2 respectively, effectively can prevent vertical loading board 1 coming off in overhead traveling crane hoisting process at vertical loading board 1 two ends.
