Background technique
The building machineries such as hydraulic crawler excavator, for the swing of machine when balanced operation, are typically necessary in operation process
Configured with counterweight.Traditional counterweight is by counterweight crust two parts of hollow form into counterweight, and one of counterweight crust is equipped with
Concrete filling exit reaches specified weight to counterweight enclosure interior fill concrete by concrete filling exit, then makes
It is vibrated the air inside with venting with tamping equipment appropriate, is sealed after concrete setting.
Due to integrally filling in counterweight crust, internal filling concrete can only be air-dried solid this counterweight by filling aperture
Change, it is different to be easy to produce air-dried speed, the halfway phenomenon of air dry cure, and the internal curing for eventually leading to counterweight is bad, no
Uniformly, the presentation qualities such as early stage corrosion, pull-away inside counterweight are caused.
Summary of the invention
The present invention is directed to the problem of traditional counterweight process and proposes the system of novel counter weight of excavator a kind of
Make method.
In order to achieve the above object, the present invention is realized using following technical solutions:
A kind of manufacturing method of counter weight of excavator, includes the following steps:
(1) counterweight crust of the production with filling exit and side opening；
(2) the crust cover board being adapted with counterweight crust side opening is made, multiple through-holes, crust are set on the crust cover board
Cover board and counterweight crust are combined into counterweight cavity plate；
(3) the counterweight punch-pin adaptable with through-hole on crust cover board is made；
(4) counterweight cavity plate and counterweight punch-pin are assembled, filler is added in filling exit；
(5) it extracts counterweight punch-pin after object curing molding to be filled out, stands or ventilation is completed up to filler air-dries；
(6) pellet that batch making and through-hole are adapted, is inserted into one or more into through-hole, adjusts balance weight.
Preferably, in surface fixing trim cover plate after the completion of the step (6).
Preferably, the shape of the through-hole cross section is any one or a few in circle, polygon or ellipse.
Preferably, the filler in the step (4) is concrete and/or steel.
Preferably, the pellet material in the step (6) is concrete and/or steel.
Compared with prior art, the advantages and positive effects of the present invention are:
1. being air-dried using multiple through-holes, is conducive to the Quick-air-drying solidification of the filler materials such as internal concrete, greatly shortens counterweight
The air dry cure time.
2. can realize the increase and decrease of counterweight overall weight, it can be achieved that industrialization by the increase and decrease quantity pellet different with material
Pipelining effectively improves production efficiency.
3. its internal Concrete Filled air dry cure is good, and can be effectively controlled, promotes presentation quality.

Specific embodiment
To better understand the objects, features and advantages of the present invention, right combined with specific embodiments below
The present invention is described further.It should be noted that in the absence of conflict, the spy in embodiments herein and embodiment
Sign can be combined with each other.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other modes described herein are different from, therefore, the present invention is not limited to the specific of specification is described below
The limitation of embodiment.
Embodiment 1, as shown in Figs. 1-5, the present embodiment provides the specific process steps of the manufacturing method of counter weight of excavator.
(1) hollow counterweight crust 1 of the production with filling exit and side opening, filling exit are located at the top of counterweight crust 1,
For filling filler 8, the open face of counterweight crust 1 in any one side of counterweight crust 1, be typically chosen cross-sectional area compared with
Big side is as open face；
(2) the crust cover board 2 being adapted with 1 side opening of counterweight crust is made, multiple through-holes 3 are set on the crust cover board 2,
Crust cover board 2 and counterweight crust 1 are combined into counterweight cavity plate 4, can be combined using the modes such as welding or bolt fixation；
(3) the counterweight punch-pin 5 adaptable with through-hole 3 on crust cover board 2 is made, the effect of counterweight punch-pin 5 is to be inserted into before filling the container
Counterweight cavity plate 4, so that the filler 8 after filling has multiple through-holes；
(4) counterweight cavity plate 4 and counterweight punch-pin 5 are assembled, filler 8 is added in filling exit, the material of filler 8 can be concrete
Or the leftover bits and pieces of steel；
(5) counterweight punch-pin 5 is extracted after object 8 to be filled slightly curing molding out, whole placement or ventilation are completed up to filler air-dries；
(6) pellet 6 that batch making and through-hole are adapted, is inserted into one or more into through-hole, adjusts balance weight, that is, passes through
Increase and decrease quantity or 6 material of pellet of pellet 6 to adjust balance weight, the material of pellet 6 can be under concrete or steel
Heel, save the cost.
