The utility model relates to a kind of engineering machinery counter weight Self-loading-unloading mechanism, and it comprises jib, configuration handling steel wire rope, counterweight hoisting frame, pulley, counterweight and turntable; Wherein, described configuration handling steel wire rope one end is by one first pinned connection on jib, and it walks around described pulley, and the other end is connected with counterweight by one second bearing pin; Described counterweight hoisting frame is arranged on turntable, and can to movement before and after turntable; Described pulley is articulated on counterweight hoisting frame.Engineering machinery counter weight Self-loading-unloading mechanism of the present utility model rises and falls in process in connection counterweight and counterweight, adjustment space is large, connect easy to loading and unloading, as there is counterweight in the process of rising and falling, all around any direction is eccentric, also the counterweight handling steel wire rope by herringbone structure adjusts automatically, and location is simple accurately in operating process, have lifting steadily, can automatically adjust, easy to operate, safety with reliably, the plurality of advantages such as cost is low.
Description
Technical field
The utility model relates to a kind of composition mechanism of engineering machinery, is specifically related to a kind of engineering machinery counter weight Self-loading-unloading mechanism, belongs to technical field of engineering machinery.
Background technology
Engineering machinery counterweight install and handling time, the lifting of counterweight is realized by the following two kinds mode: one is by auxiliary equipment, carries out installation and removal after winching to installation site as counterweight risen by crane.This kind of mounting means must by relevant auxiliary equipment, and too complexity, waste of manpower, high cost and poor reliability, completely by the qualification of the operating personnel of auxiliary equipment, are installed in location.Two is that engineering machinery installs balance weight auto-loading additional and unloads oil cylinder, and the moving up and down of weight balancing oil cylinder promotes counterweight and carry out to installation site being installed on dismounting.This kind of mounting means can save manpower, easy and simple to handle, but need additionally to increase oil cylinder, operating valve, balanced valve and pipeline, cost is high and balance weight auto-loading unloads oil cylinder lifting counterweight, in counterweight eccentric or operation left and right oil cylinder is asynchronous time, the easy unstability of weight balancing oil cylinder cylinder bar, cause oil cylinder to damage, there is potential safety hazard.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel engineering machinery counter weight Self-loading-unloading mechanism, to overcome described defect of the prior art.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of structure simple, safe and reliable, portable and effective and the low engineering machinery counter weight Self-loading-unloading mechanism of cost.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of engineering machinery counter weight Self-loading-unloading mechanism, and it comprises jib, configuration handling steel wire rope, counterweight hoisting frame, pulley, counterweight and turntable; Wherein, described configuration handling steel wire rope one end is by one first pinned connection on jib, and it walks around described pulley, and the other end is connected with counterweight by one second bearing pin; Described counterweight hoisting frame is arranged on turntable, and can to movement before and after turntable; Described pulley is articulated on counterweight hoisting frame.
Engineering machinery counter weight Self-loading-unloading mechanism of the present utility model is set to further: described configuration handling steel wire rope carry from above rope, roller and under carry Suo Zucheng; Described roller is connected to the one end carrying rope; Carry rope under described and walk around described roller, and be arranged on the both sides of roller.
Engineering machinery counter weight Self-loading-unloading mechanism of the present utility model is also set to: described configuration handling steel wire rope is herringbone structure.
Compared with prior art, the utility model has following beneficial effect: engineering machinery counter weight Self-loading-unloading mechanism of the present utility model rises and falls in process in connection counterweight and counterweight, adjustment space is large, connect easy to loading and unloading, as there is counterweight in the process of rising and falling, all around any direction is eccentric, also the counterweight handling steel wire rope by herringbone structure adjusts automatically, and location is accurately simple in operating process, have lifting steadily, can automatically adjust, easy to operate, safety with reliably, the plurality of advantages such as cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of engineering machinery counter weight Self-loading-unloading mechanism of the present utility model.
Fig. 2 is the configuration handling construction of wire rope schematic diagram in Fig. 1.
Detailed description of the invention
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of engineering machinery counter weight Self-loading-unloading mechanism, and it is assembled by a few parts such as jib 1, configuration handling steel wire rope 2, counterweight hoisting frame 3, pulley 4, counterweight 5 and turntables 6.
Wherein, described configuration handling steel wire rope 2 one end is connected on jib 1 by one first bearing pin 7, and it walks around described pulley 4, and the other end is connected with counterweight 5 by one second bearing pin 8.
Described counterweight hoisting frame 3 is arranged on turntable 6, and can to movement before and after turntable 6.Described pulley 4 is articulated on counterweight hoisting frame 3.
Further, described configuration handling steel wire rope 2 in herringbone structure, its carry from above rope 21, roller 22 and under carry rope 23 and form.Described roller 22 is connected to the one end carrying rope 21; Carry rope 23 under described and walk around described roller 22, and be arranged on the both sides of roller 22.
The operation principle of engineering machinery counter weight Self-loading-unloading mechanism of the present utility model is as follows: counterweight 5 is put in ground, jib 1 is lain prone flat, by the first bearing pin 7 counterweight loaded and unloaded steel wire rope 2 one end and jib 1 is hinged, upwards luffing is to certain angle (reducing the distance of the first bearing pin 7 to the second bearing pin 8), counterweight is loaded and unloaded steel wire rope 2 and walk around the pulley 4 be arranged on counterweight hoisting frame 3, the other end is hinged with counterweight 5 by the second bearing pin 8, then downward luffing (distance of the first bearing pin 7 to the second bearing pin 8 is joined in increase) is to certain angle, counterweight 5 to installation site is mentioned by counterweight handling steel wire rope 2, insert fixed pin shaft 9 by hinged to counterweight 5 and turntable 6, the weight of counterweight 5 is all born by fixed pin shaft 9, and counterweight handling steel wire rope 2 is no longer stressed, easily extracts the first bearing pin 7 to the second bearing pin 8, pull down counterweight handling steel wire rope 2, so far counterweight installation process completes.Counterweight unloading process is contrary with installation process.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
