Description

The spacing pin anti-slip device of a kind of crane hoisting

Technical field

The utility model belongs to hoisting crane technical field, particularly relates to the spacing pin anti-slip device of a kind of crane hoisting.

Background technology

Hoisting crane is a kind ofly widely used in the professional equipment of the places such as industrial and mining enterprises, railway, harbour, warehouse for handling weight; heavy hammer limiting switch is the common limiting and protecting device that hoists, and the effect of hoisting crane heavy hammer limiting switch is the limiting and protecting device preventing accident of rushing to summit in rising at the major-minor hook in operation that hoists.

Metallurgical, machinery industry needs to carry out crane loading operation in producing, therefore lifting position-limit switch prevents to rush to summit the fender guard of class accident in lifting operation, whether the limit switch reliable in action that hoists directly affects the safety of the operation that hoists, the harm that brings of rushing to summit when especially lifting dangerous article is larger, and the heavy hammer limiting switch action stop lever reliably whether weight is spacing is that it is crucial, stop lever has problem to cause to rush to summit, cause the generation of grave accident, staff comes to harm and device damage, run to crane safety and bring larger puzzlement, problem common is at present:

1) existing crane hoisting limiting and protecting device pin (block material) has capitate block material, steel pipe, angle steel etc. to be connected with heavy hammer limiting switch with connection cord to use, the impact of circumscribed height in crane running process, the long pin that causes of connection cord rocks, be wound around with main hoist rope, thus cause the limiting and protecting device action inefficacy that hoists, class of rushing to summit accident;

2) the many employings of the limiting and protecting device that hoists 2 connection cords of existing hoisting crane major-minor hook forms connect, and when leading (pair) hook and colliding and hoist limiting block lever apparatus, pin can occur and break away, cause the limit switch action inefficacy that hoists because connection cord is long;

3) due to hoist limiting and protecting device and pin connection cord long, cause comparatively large and main (pair) hook steel rope of pin amplitude of fluctuation to rub, thus affect the service life of steel rope.

Therefore the design of lifting of travelling crane spacing pin is unreasonable is the subject matter existed at present, needs to take appropriate measures improvement, just can reach minimizing accident, improve device security reliability.

Summary of the invention

Technical problem to be solved in the utility model is to provide the spacing pin anti-slip device of a kind of crane hoisting, stop the spacing inefficacy of crane hoisting and cause the problems such as class safety misadventure of rushing to summit, actv. improves equipment operation rate, reduce fault rate, rational in infrastructure, element is compact, accurate positioning, safe and reliable, practical.

The utility model solves the technical scheme that its technical matters adopts: provide a kind of crane hoisting spacing pin anti-slip device, comprise the main drum be arranged in parallel, loose drum, described main drum, below loose drum, main hook and auxiliary hook are housed respectively, it is characterized in that, the outside of described main drum and loose drum arranges main hook heavy hammer limiting switch and auxiliary hook heavy hammer limiting switch respectively, described main hook heavy hammer limiting switch and auxiliary hook heavy hammer limiting switch are connected by the two ends of hauling rope pin spacing with anticollision respectively, the spacing pin of described anticollision is horizontally placed on the below of main drum and loose drum, and be positioned at above main hook and auxiliary hook.

Be connected with the frame between main drum, loose drum by hauling rope in the middle part of the spacing pin of described anticollision.

Manage under the described hauling rope overcoat with being connected in the middle part of the spacing pin of anticollision has anti-slip hauling rope, under described anti-slip hauling rope, pipe is fixed in frame.

Pipe to be diameter the be steel pipe of 16 millimeters under described anti-slip hauling rope.

The described hauling rope overcoat be connected with the spacing pin two ends of anticollision has heavy hammer limiting switch hauling rope skirt, and described heavy hammer limiting switch hauling rope skirt is fixed in frame.

Described heavy hammer limiting switch hauling rope skirt to be diameter be 16 steel pipe.

Described main hook heavy hammer limiting switch is connected with hauling rope by wire rope grip with auxiliary hook heavy hammer limiting switch, and described hauling rope is connected by the spacing pin of wire rope grip and anticollision.

Described hauling rope to be diameter the be steel rope of 5 millimeters.

Beneficial effect

The utility model has the advantage of, actv. solves the inhibiting device that to cause with steel rope generation winding because hauling rope is long hoisting and lost efficacy, original weight limiting block lever apparatus adds the spacing skirt of weight, avoid driving to run at cart and in the process that hoists, pin steel rope occurs significantly to swing, add anti-slip skirt device leading during (pair) hook rises collides that pin can not break away, the problem such as come off simultaneously, adopt gauge member, low price, improves implementation cost low; Actv. solves driving class accident of rushing to summit and occurs, and applicability is strong, improves, have certain application value to other similar devices.
