Description
Technical field
The utility model relates to a kind of gear controller, particularly relates to a kind of crawler crane of novel variable-amplitude auxiliary arm fall line mode.
Background technology
Along with the quickening of Urbanization in China, economic fast development, the scale of state fundamental construction is increasing, and weight and the lifting altitude of the article of needs lifting are increasing, crawler crane more and more shows its preceence, and crawler crane obtains swift and violent development.Crawler crane in order to improve its lifting altitude and work range, usual design and installation variable-amplitude auxiliary arm.
As shown in Figure 1, principal arm system has a special elevator joint near jib heel, and elevator joint is provided with variable-amplitude auxiliary arm luffing elevator (sequence 02), and variable-amplitude auxiliary arm luffing elevator (sequence 02) is upper is wound around variable-amplitude auxiliary arm variable-amplitude steel wire rope (sequence 04); Principal arm system has a special transition arm joint near arm head place, this transition segment is provided with variable-amplitude steel wire rope guide pulley device (sequence 03); After variable-amplitude steel wire rope guide pulley device (sequence 03), arrive variable-amplitude auxiliary arm support (sequence 07-2) head assembly pulley after variable-amplitude auxiliary arm variable-amplitude steel wire rope (sequence 04) exports from variable-amplitude auxiliary arm luffing elevator (sequence 02), be then wrapped on variable-amplitude auxiliary arm support (sequence 07-1, sequence 07-2) head assembly pulley successively; Regained by variable-amplitude auxiliary arm luffing elevator (sequence 02) during work or release variable-amplitude auxiliary arm variable-amplitude steel wire rope (sequence 04) and reach the object that variable-amplitude auxiliary arm (sequence 08) changes amplitude.From the hoist rope (sequence 05) that the elevator that hoists (sequence 01) exports, the hoist rope guide pulley device (sequence 06) successively on variable-amplitude auxiliary arm support (sequence 07), finally arrives variable-amplitude auxiliary arm arm head leading sheave (sequence 010), thus realizes lifting.Wherein the concrete pulley arrangements of variable-amplitude auxiliary arm support hoist rope guide pulley device as shown in Figure 9.
As shown in Figure 7, during principal arm operating mode, from the hoist rope (sequence 05) that the elevator that hoists (sequence 01) exports, directly through the hoist rope guide pulley device (sequence 012) of principal arm head, thus realize lifting; As seen from Figure 8, because elevator has certain width, hoist rope can move around along the direction of arrow shown in Fig. 8 on elevator, and when hoist rope changes to opposite side from elevator side, hoist rope is passed by certain angle.
Playing arm is the process that boom system is lifted to required working condition position by hoisting crane.Can, for crawler crane especially large tonnage crawler crane, playing an arm operating mode be the most dangerous, worst operating mode, play the success or not of arm and be directly connected to and carry out operation, or even the danger such as framing member damages, complete machine is tumbled.Be illustrated in figure 5 crawler crane principal arm operating mode and play arm schematic diagram, as seen from Figure 5, when playing arm, jib can produce a downward amount of deflection, jib weight is especially larger near the arm head place heavier amount of deflection of weight, along with the increase of amount of deflection, the difficulty playing arm also strengthens, therefore, and the amount of deflection of jib when control the difficulty of jib and play arm.
There is following shortcoming in above-mentioned crawler crane:
1. need special variable-amplitude steel wire rope guide pulley device, as shown in Figure 2, and for being fixedly connected with this variable-amplitude steel wire rope guide pulley device: special principal arm transition segment, the commonality of principal arm arm internode is reduced, increase the overall processing complexity of jib, increase cost;
2. what principal arm transition segment can only be fixed be assemblied near the position of arm head, increases complexity when installing;
3. the variable-amplitude steel wire rope guide pulley device pulling force that needs special reinforcement to produce to adapt to variable-amplitude steel wire rope in a-quadrant as shown in Figure 4, principal arm transition segment installation site, this transition segment weight is caused to increase, and the installation site of this transition segment must near arm head, whole jib is increased near arm head place weight, larger the produced capsizing moment of weight of jib self and amount of deflection when playing arm larger, an arm difficulty of complete machine is larger;
4. crawler crane is owing to being subject to transportation clearance and transport heavy quantitative limitation, often need before and after operation to carry out dismounting, variable-amplitude auxiliary arm variable-amplitude steel wire rope also needs winding repeatedly, be illustrated in figure 6 the schematic diagram of variable-amplitude steel wire rope fall line when variable-amplitude auxiliary arm is installed, as can be seen from the figure, variable-amplitude steel wire rope walks on the rope at variable-amplitude auxiliary arm frame upper, because variable-amplitude auxiliary arm has needed various function, this frame upper has a considerable amount of annex, as attached smallclothes such as arm-tie brackets, inevitably interfere with these annexes when variable-amplitude steel wire rope wire rope handling, cause the damage of framing member or the wearing and tearing etc. of steel rope,
5. under principal arm operating mode, hoist rope arrives the hoist rope guide pulley device of principal arm head after lifting mechanism exports, when hoist rope can be interferenceed with the variable-amplitude steel wire rope guide pulley device on principal arm transition segment in moving process on lifting mechanism, framing member and steel rope is caused to damage, therefore under principal arm operating mode, need variable-amplitude steel wire rope guide pulley device to remove, increase the complexity of dismounting;
6., during transport, principal arm transition segment is due to variable-amplitude auxiliary arm variable-amplitude steel wire rope guide pulley device superelevation, and as shown in Figure 3, the height of H, needs this guide pulley device to remove transport separately, increase traffic cost, reduce efficiency simultaneously.
