Description

A kind of excavator loading machine is with structural member counterweight and production method thereof

Technical field

The present invention relates to counterweight and make the field, especially relate to a kind of excavator loading machine with structural member counterweight and production method thereof.

Background technology

Excavator, loader need be installed counterweight in use on car body, come balancing vehicle, avoid vehicle nose or rollover; The casting of existing excavator, loader casting counterweight needs a large amount of foundry iron and various rare element usually; Also need quartz sand, graphite, alcohol, resin, curing compound, coke etc. in addition, the energy consumption amount is big, and cost is high; The counterweight center of gravity is high, poor stability during use.

Chinese patent notification number CN102407564A discloses the preparation method of a kind of vehicle with concrete weight coating spare April 11 2012 day for announcing, and making step is: (1) is processed basin shape housing with sheet metal through cutting, punching press; (2) weld centre bore pipe, fixing hole pipe and hole for hoist pipe respectively in the inside of basin shape housing; (3) between the inwall and centre bore pipe and fixing hole pipe of basin shape housing, with the webbed metallic framework of welded wire; (4) cement, stone, stone flour, coarse sand, diamond dust, flyash, curing compound, blender and water are not got in the mark score by weight; Each raw material of being got mixed to stir process concrete inserts (5) the concrete inserts that stirs is cast in the basin shape housing natural air drying after the compacting; That the present invention has is with low cost, process simple advantage; Weak point is that inserts is easy to crack, thereby breaks away from housing; Damage housing owing to inertia causes the inserts impact objectives in the use, counterweight is short application life; The counterweight center of gravity is high, poor stability during use.

Summary of the invention

The object of the invention is to overcome that the counterweight of prior art is fragile, application life short, the deficiency of center of gravity high stability difference, provides the excavator loading machine of a kind of not fragile, long service life, the low good stability of center of gravity to use the structural member counterweight.

Another object of the present invention is to provide the production method of a kind of excavator loading machine with the structural member counterweight.

The technical scheme that the present invention solves its technical problem employing is:

A kind of excavator loading machine is used the structural member counterweight; Comprise casing and be filled in the inserts in the said casing, said inserts is processed by following components in weight percentage: iron sand 30 ~ 50%, shot 20 ~ 30%; Quartz sand 12.5 ~ 41%; Gangue 1 ~ 5%, cement 2.5 ~ 8%, said inserts layering is filled.The present invention processes simply, and energy consumption cost is low, and iron sand, quartz sand, gangue wide material sources, raw material are easy to obtain, and with each inserts layering filling, has overcome between the inserts of different rerum naturas and is difficult for mixing, inserts problem easy to crack.

As preferably, be followed successively by the mixing filling bed of material that iron sand is filled the bed of material, the shot filling bed of material and processed by quartz sand and gangue from bottom half to top.Heavy inserts is seated in lower box, and the counterweight center of gravity that makes is low, good stability during use.

As preferably, the proportion of said iron sand is 4.2 ~ 7.2t/m3.

As preferably, said quartz sand particle size 1 ~ 20mm, wherein particle diameter is that the quartz sand percentage by weight of 1 ~ 4mm is 20 ~ 30%, particle diameter is 70 ~ 80% greater than 4mm smaller or equal to the quartz sand percentage by weight of 20mm.The quartz sand thickness combines, and has reduced the void content of mixing inserts, has improved the density of mixing inserts, has also improved the solidifiability that mixes inserts.

As preferably, the inwall plane of symmetry of said casing is welded with the skeleton that is made up of reinforcing bar.Skeleton plays fixation to the inserts that solidifies, and prevents that inserts shrinkage and cabinet wall break away from, and owing to inertia, inserts and cabinet wall collide and the damage casing when avoiding the use of.

As preferably, said cabinet wall is bonded with the elastic caoutchouc liner that thickness is 2 ~ 4cm.The inserts heat of can alleviating the elastic caoutchouc liner rises to the destruction of casing, also can prevent to break away from cabinet wall after the inserts shrinkage, in causing using because inertia inserts damaged in collision casing, but also noise reduction of elastic caoutchouc liner, absorbing, thereby prolong the casing life-span.

A kind of excavator loading machine is with the production method of structural member counterweight, and described production method comprises the steps:

(1) take by weighing required iron sand, shot, quartz sand, gangue and cement successively, said cement is divided into 4 parts;

(2) with iron sand and 1 part of cement mixing, the water mixing that adds iron sand weight 1 ~ 2% is then processed the iron sand inserts, described iron sand inserts is placed bottom half, jolt ramming then;

(3) with shot and 1 part of cement mixing, the water mixing that adds shot weight 1 ~ 2% is then processed the shot inserts, described shot inserts is placed on the iron sand inserts jolt ramming then;

(4) with quartz sand, gangue and 2 parts of cement mixings, the water mixing that adds quartz sand and gangue gross weight 8 ~ 10% is then processed the mixing inserts, described mixing inserts is placed on the shot inserts, and jolt ramming then, natural air drying gets final product.

Each inserts layering is up filled from bottom half successively, and heavy inserts is filled in lower box, and prepared structural member counterweight center of gravity is low, uses good stability.

As preferably, the percentage by weight of each component is following in the step (1): iron sand 30 ~ 50%, and shot 20 ~ 30%, quartz sand 12.5 ~ 41%, gangue 1 ~ 5%, cement 2.5 ~ 8%, the percentage by weight sum of each component is 100%.

As preferably, the inwall plane of symmetry of casing is welded with the skeleton that is made up of reinforcing bar described in the step (2).

As preferably, the inwall of casing described in the step (2) is bonded with the elastic caoutchouc liner that thickness is 2 ~ 4cm.

The present invention has following beneficial effect: (1) processing is simple, and is much lower with existing casting counterweight specific energy consumption; (2) the packing material collocation is reasonable, and proportion is high, can significantly improve the proportion of structural member counterweight; (3) the inwall plane of symmetry of casing is welded with skeleton or is provided with the elastic caoutchouc liner, can avoid or alleviate the rising-heat contracting-cold of inserts, and inserts is not easy to crack, can not separate with cabinet wall, and casing is not fragile, structural member counterweight long service life.
