The specific embodiment
Core of the present utility model provides a kind of take-up device that is used for crawler crane, and it is simple in structure, easy to operate, and has lower cost.Another core of the present utility model provides a kind of crawler crane that comprises above-mentioned take-up device.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 4 and Fig. 5, Fig. 4 is the structural representation of the utility model crawler crane that a kind of specific embodiment provides; Fig. 5 is the jib structure scheme drawing of crawler crane shown in Figure 4.
In a kind of specific embodiment, crawler crane provided by the utility model comprises caterpillar chassis and turntable, and the bottom of mast 21 is articulated on the described turntable, and the bottom of jib 22 is articulated on the described turntable equally.
Under the principal arm operating mode, jib 22 can be understood as and only comprises principal arm; Under tower auxiliary operating mode, jib 22 can be understood as the integral body that comprises principal arm, auxiliary.
For the smooth amount of deflection that realizes the luffing of jib 22 and alleviate jib 22, can between mast 21 and jib 22, take-up device be set.
Described take-up device comprises first strain component 23 and second strain component 24.
Can mast 21 be risen by drive element, can make described crawler crane change operating condition over to like this, and make 23 tensionings of first strain component, rotate around its bottom, realize the luffing of jib 22 thereby drive jib 22.
First end of second strain component 24 is connected between the both ends of jib 22, and particular location can further be determined according to actual condition, usually above-mentioned first end is connected in the position that may produce on the jib 22 than high camber.Second end of second strain component 24 is connected between the both ends of first take-up device 23, and as shown in Figure 5, above-mentioned second end can be connected in the middle part of first take-up device 23 usually.
Owing to may take place to have applied the pulling force that makes progress than the position of high camber at jib 22 by second strain component 24, the part gravity of jib 22 is balanced, so its overall force-bearing situation improves, and its amount of deflection will significantly alleviate.
The end of first end of second strain component 24 and second end, jib 22, above-mentioned three distribution triangular in shape, therefore the top of mast 21 can act on the end and the bigger position of middle part amount of deflection thereof of jib 22 simultaneously by first strain component 23 and second strain component 24, described take-up device thereby can successfully realize the luffing of jib 22, and can effectively alleviate the amount of deflection of jib 22; Compare with the waist rope with steel rope of the prior art, described take-up device simple in structure, the length of second strain component 24 significantly are shorter than the length of prior art middle part of the side rope, and cost is therefore lower, and easy to operate.
Please also refer to Fig. 6 and Fig. 7, Fig. 6 is the partial enlarged drawing at B position among Fig. 5; Fig. 7 is that the C of single arm-tie and double clamp among Fig. 6 is to view.
Can the tracked construction equipment in the above-mentioned specific embodiment be improved.
At this moment, second end of second strain component 24 can be hinged by the above-mentioned bearing pin and first strain component 23.As the case may be, second end of second strain component 24 can be selected the jointed shaft of a suitable person as itself and first strain component 23 among a plurality of described bearing pins.
As previously mentioned, first end of second strain component 24 is connected in the middle part of jib 22.Connection otic placode (not adding Reference numeral among the figure) can be set on jib 22, and first end of second strain component 24 can be connected with jib 22 by connecting otic placode.
Structure to second strain component 24 also can be carried out some improvement.
For example, second strain component 24 can have the drawplate type structure.Second strain component 24 can comprise two arm-ties 241 of at least one joint and the single arm-tie 242 of at least one joint, and two arm-ties 241 are connected by connecting pin 243 with single arm-tie 242.Two arm-ties 241 and single arm-tie 242 are a joint among Fig. 6, obviously should not be limited to this.Certainly, second strain component 24 can also comprise the two arm-ties of at least one joint and at least one joint three arm-ties, and two arm-ties are connected by connecting pin equally with three arm-ties.This specific embodiment only describes in detail to second strain component 24 that is made of two arm-ties 241 and single arm-tie 242.
Can take measures, the length of second strain component 24 can be adjusted.For example, offer at least two connecting bores 2411 on two arm-ties 241, each connecting bore 2411 distributes along the length direction of two arm-ties 241, and connecting bore 2411 also can be arranged at other arm-ties, in for example single arm-tie 242 or three arm-ties.Like this, connecting pin 243 can be arranged in arbitrary connecting bore 2411, and the length of second strain component 24 just can change.Certainly, the length that changes second strain component 24 by other modes also is fine.
At this moment, when the length of jib 22 changes under different operating conditions, the connection location at second strain component, 24 two ends can remain unchanged, the length that only needs suitably to adjust second strain component 24 can make it be applicable to new operating mode, so just avoid loaded down with trivial details dismounting operation, significantly simplified operating process.Simultaneously, the length of second strain component 24 can be adjusted its comformability is significantly improved, and then arm 22 deflection upward can effectively avoid lift heavy the time, has improved the lifting performance of arm 22.
In addition, single arm-tie 242 of second strain component 24 and two arm-tie 241 all can be formed by a blanking of high-strength panel; With respect to by joint, connect fork bonded assembly steel rope, like this, not only processing technology is simple, and can effectively avoid coming off in the junction, helps improving the safety of equipment.
The utility model provides the structure of other parts of crawler crane to please refer to prior art, and this paper repeats no more.
More than crawler crane provided by the utility model and take-up device thereof are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
