The invention discloses a method for making a counterweight for an excavator, which is characterized by comprising the following steps of: firstly, welding and constructing a prefabricated cement block steel frame structure, and arranging the welded prefabricated cement block steel frame structure in a mould; secondly, filling a material to be filled into the mould, air drying after the filling is finished, then demoulding to obtain a prefabricated cement block, finishing the prefabricated cement block, and protruding the prefabricated cement block steel frame structure from the cement block; thirdly, making a counterweight shell panel and sealing plate; fourthly, welding the counterweight shell panel and the prefabricated cement block steel frame structure together, and filling cement in a gap at the joint of the counterweight shell panel and the prefabricated cement block and air drying; and fifthly, assembling and welding the counterweight shell sealing plate and panel, as well as the prefabricated cement block steel frame structure together, then coating and finishing the making of the counterweight. By dividing the counterweight making into prefabricated cement block making and counterweight shell making, the invention enables a counterweight shell not to be easy to deform, ensures the quality of the counterweight shell and enhances the production efficiency.
Description
Technical field
The present invention relates to a kind of counterweight manufacture method, be specifically related to a kind of counterweight manufacture method that is used for excavator.
Background technology
The main purpose of excavator is a digging material and transfer to the emptying point from the face of land, goes back to excavation site after the discharging again, repeats.At present the excavator that generally uses is a hydraulic crawler excavator, has construction maneuverability, advantage that efficient is high, thereby is widely used in occasions such as the foundation dredging of building construction and the cleaning after the completion, urban duct laying, construction of water conservancy works.Excavator generally is made up of several parts such as equipment, slewing equipment, running gear and control device, and slewing equipment and running gear are the bodies of excavator, and equipment is transferred on slewing equipment, and slewing equipment is fixed on the underframe of running gear.Described equipment is a device of directly finishing mining task, partly be made up of swing arm, dipper, scraper bowl etc., thereby swing arm rises and falls, dipper stretches and mining task is finished in the scraper bowl rotation.
At present, excavator is in operation process, and the swing of machine during for the balance excavator operation generally all needs to dispose counterweight.Traditional counterweight mode of production is a can cement mixed pulp in the good counterweight housing of welding, and whole then placement is waited for and being solidified.Referring to shown in Figure 1, counterweight comprises a counterweight housing 1, offers filling exit 2 on the counterweight housing 1, and manufacturing process is: after counterweight housing welding is finished, the cement mixing slurry is injected in the counterweight housing until reaching specified wt from filling exit, dry then, sealing of hole.Though the said method technological process is comparatively simple, and is easy to operate, can adapt to general production demand, but this mode of production is the building formula mode of production, have following point: 1. can thing cement mixing slurry pushes the counterweight housing, and housing distortion is serious, difficult quality guarantee; 2. need carry out can adjustment, Weight control difficulty during each counterweight can; 3. it is low to make production efficiency; 4. cause the production scene filthy in the manufacture process, management is also comparatively difficult; 5. this canning means is the building formula mode of production, and counterweight welding, coating process then adopt the industrial flow-line formula mode of production, and both are in conjunction with difficulty, and the industrialized mass difficulty is bigger.
Summary of the invention
The object of the invention provides a kind of counterweight manufacture method that is used for excavator, uses this method, makes the counterweight housing not yielding, and quality is guaranteed, and has improved production efficiency.
For achieving the above object, the technical solution used in the present invention is: a kind of counterweight manufacture method that is used for excavator comprises the following steps:
(1) prefabricated cement block steel skeleton construction is built in welding, and the prefabricated cement block steel skeleton construction after will having welded is positioned in the mould;
(2) material to be filled is poured in the described mould, can is dried after finishing, and the demoulding then obtains prefabricated cement block and to its finishing, makes prefabricated cement block steel skeleton construction protrude cement block;
(3) make counterweight case panel and shrouding;
(4) counterweight case panel and prefabricated cement block steel skeleton construction are welded, the gap employing cement of counterweight case panel and prefabricated cement block junction is filled up and is dried;
(5) with counterweight housing shrouding and panel and prefabricated cement block steel skeleton construction assembly welding, the counterweight manufacturing is finished in application then.
In the technique scheme, described counterweight manufacturing is decomposed into prefabricated cement block manufacturing and housing manufacturing, prefabricated cement block manufacturing replaces before traditional grouting formula and produces, promptly by actual required counterweight shape, prefabricated at precasting yard, parts as counterweight, incorporate counterweight production into, described prefabricated cement block, be with yellow sand, ore in sand form, iron ore, barite, other ore, in iron and steel or other tubulose material one or more and cement is proportioning by a certain percentage, concrete can material after the preparation is filled into interior prefabricated the forming of mould that inside is placed with prefabricated cement block steel skeleton construction, concrete fill material and proportioning require according to actual density and decide, to reach difformity, the requirement of Different Weight.When counterweight is made, the can material is poured in the mould of putting up, make prefabricated cement block, prefabricated cement block can be an integral body, it also can be the combination of several prefabricated cement blocks separately, in making prefabricated cement block process, by with mount pad, various counterweight inner structural members such as lifting seat make up prefabricated in the lump, shortened the Workshop Production link of counterweight, prefabricated cement block shape is with inclined to one side 10～40mm in the counterweight housing profile, prefabricated cement block steel skeleton construction constitutes the reservation pad around protruding prefabricated cement block, is used for counterweight capping component such as counterweight case panel and counterweight housing shrouding assembly welding are successively finished the manufacturing of counterweight.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention is by being decomposed into the counterweight manufacturing prefabricated cement block manufacturing and the manufacturing of counterweight housing, carry out prefabricated cement block production earlier, and will produce good prefabricated cement block and counterweight housing and carry out assembly welding, finish the counterweight manufacturing, compare with counterweight manufacture method in the past, need not again the can material directly to be poured into the counterweight housing, solved the can material and directly poured into the counterweight housing and cause the counterweight housing distortion, the problem that weight mass can't guarantee;
2. but the prefabricated production of can scale of the prefabricated cement block among the present invention has improved production efficiency, and filling quality is stable;
3. can is transferred to precasting yard and carries out, and has got rid of the can of counterweight housing production department and has polluted, and helps production management;
4. the present invention has changed the traditional building formula production method of counterweight manufacturing, is fit to large-scale industrialization production.
