Abstract
The utility model relates to a rotary drilling rig balance weight combined device which comprises a balance weight fixing frame (1), a balance weight stay bar (2), a clump weight (3) and an end clump weight (4), wherein the balance weight stay bar (2) is fixed on a rotary platform tail frame of a rotary drilling rig, the clump weight (3) is connected in series on the balance weight stay bar and is fastened on the balance weight fixing frame by threads, and adjustment on the entire weight of a balance weight can be realized by changing the number of clump weights which are connected in series. The rotary drilling rig balance weight combined device has the following beneficial effects: by adopting an adjustable structure, the weight of the balance weight can be adjusted appropriately according to different working conditions, so that the whole machine achieves a balanced state; and on the premise of guaranteeing safe use, the weight of the whole machine is configured optimally, so thatthe machine is convenient for disassembly during transportation, and weight unbalancing at the front part and the rear part is avoided. Simultaneously, the rotary drilling rig balance weight combined device can be adaptive to different machine types by adjusting the weight of the balance weight.
Description
Technical field
The utility model relates to a kind of rotary drilling rig counter weight device, specially refers to a kind of rotary drilling rig combinations of weights device.
Background technology
Integral arrangement is all carried out according to chassis of dredging machine form of structure in the rotary drilling rig crawler travel both domestic and external chassis of prior art, is counterbalance design fixed all generally, and is fixedly mounted on the afterbody of upper body part that can 360 ° of rotations.Because when design, the technician can only carry out the consideration of the design and installation position of counterweight weight by the required counterpoise of a certain type, the counterweights that adopt fixed profile more, weight is unique to be determined, and it is fixedly mounted on the last position of upper body, structure is single, can't realize the general of the interior different type of machines of a certain scope.Simultaneously, the work tool of rotary drilling rig needs by operation in the operating process of reality, need change.And their weight of different work tools respectively changes, and the variation of weight is also bigger sometimes.At the fixing state that is provided with of upper body afterbody, it is the most reasonable that the position of centre of gravity of complete machine is in all the time for counterweight for this, stable status.
In addition, for rotary drilling rig, because its key operation content is exactly in bored pile hole, ground, because its target is materials such as soil, cobble.When bore operation, once machinery rocks slightly, light then bucket tooth drilling machine damages, and is heavy then drill rod breaking will cause the generation of sizable economic loss and major accident.Therefore remain machinery and be in the most stable bearing state relatively, particularly allow be in the most stable relative bearing state between top facility and the rearmost counterweight in the mechanical arrangement, this seems even more important for rotary drilling rig.When transportation, on mast was packed up level frame and got on the bus, the weight concentrations caused moving behind the machine gravity in afterbody, and front and back weight is seriously lacked of proper care, and had strengthened transport difficulty, had increased the danger of transportation.
In sum, at the defective of prior art, need a kind of rotary drilling rig combinations of weights device especially, to solve above-mentioned problem.
The utility model content
The purpose of this utility model is to provide a kind of rotary drilling rig combinations of weights device, by the center of gravity that the quantity that changes counterweight is regulated rotary drilling rig, makes it to be in the most reasonable, stable status, solves the defective of above-mentioned prior art.
The technical problem that the utility model solved can realize by the following technical solutions:
A kind of rotary drilling rig combinations of weights device, comprise counterweight fixed mount, counterweight strut, balancing weight and end balancing weight, it is characterized in that, described counterweight strut is fixed on the revolving dial tailstock of rotary drilling rig, balancing weight and the series connection of end balancing weight are connected on the counterweight strut, connect with short pin between the balancing weight and be threadedly secured on the counterweight fixed mount, regulate weight by the quantity that changes the series connection balancing weight during use.Described counterweight strut adjustable length.Pass through four jiaos four short finger settings between the described balancing weight.Short pin is positioned at four corners of balancing weight.Described bolt is the M30 bolt.
Further, in the utility model, increase the combined counterbalance adjustable range.
Further, in the utility model, increase the scope of application of combined counterbalance in engineering machinery.
The beneficial effects of the utility model are:
The utility model adopts the technical scheme in the rotary drilling rig counterweight, after determining working environment, utilizes this increase and decrease structure, the assurance system can regulate counterweight in the shorter time effectively, to satisfy field requirement, reaches assembled machine balance, increase work efficiency, reduce application risk.
