Abstract
The utility model relates to a front container lifter with a movable counterweight mechanism, which comprises a lifter body, a matching block and a suspended arm assembled on the lifter body. The utility model is characterized in that the matching block is a removable matching block arranged at the tail part of the lifter body and driven by a hydraulic oil cylinder connected to the matching block to slip. The front moving position and the back moving position are respectively provided with an upper limit stop and a lower limit stop. The matching block is also provided with an upper sliding track matched with a lower sliding track arranged on the lifter body. The utility model is provided with the counterweight which can move forward and backward at the tail part of the lifter body, the equilibrant moment of the lifter body is relative to the hanging load can be increased under the condition that the counterweight is not increased, and the weight of the whole lifter is decreased under the condition that the front container lifter lifts the same rated load, so that the manufacturing cost and operating cost of the whole lifter are decreased. Meanwhile, the operating flexibility in a use process is increased.
Description
Technical field:
The utility model relates to the machinery of a kind of container transshipment, stacking, particularly a kind of improvement of container face crane of Tape movement counterweight.
Background technology:
The counterweight of existing container face crane generally all is fixed in the afterbody of car body, under length over ends of body unmodified situation, counterweight and lift heavy are complementary, if but the Container Weight that is hung is heavier, then corresponding counterweight weight is bigger, makes the weight of car load lay particular stress on; If reduce counterweight, can make troubles to the car load walking again with the increasing length over ends of body.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and providing a kind of need not increase the container face crane that counterweight can improve the Tape movement balance weight mechanism of car load lift heavy rated value.
The utility model is to solve the problems of the technologies described above by following technical scheme.It comprises car body, clump weight and is loaded on arm on the car body, it is characterized in that described clump weight is for being arranged at the removable clump weight of hull back, this clump weight is driven by the hydraulic ram that joins with it and does slippage, and the position, back is equipped with upper limit block and lower limit block respectively before moving.On clump weight, also be provided with slide rail, on this slide rail with corresponding be loaded on the car body under slide rail match.
The utility model is by installing the counterweight that can move forward and backward at hull back, under the situation that does not increase counterweight, can increase the balancing torque of car body with respect to lift heavy, make container face crane under same nominal lift heavy situation, reduce complete vehicle weight, make the manufacturing cost and the use cost of car load reduce, also increased the flexibility of operation in the use simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 2;
Fig. 4 is the C-C cutaway view of Fig. 2.
Among the figure:
1-car body 2-clump weight; The last slide rail of 3-;
The 4-glidepath; The 5-hydraulic ram; 6-upper limit block;
7-lower limit block; The 8-arm.
The specific embodiment:
As shown in Figure 1, the utility model comprises car body 1, clump weight 2 and arm 8, arm 8 is loaded on the car body 1, it is characterized in that it is that afterbody at car body 1 is provided with one and can makes the clump weight 2 that moves forward and backward as required, when the handling Different Weight, the distance of clump weight 2 scalable itself and suspension transferring machine center of gravity makes it form a balancing force distance with respect to handling weight, and do not need to increase the weight of clump weight, thereby reached the purpose that the utility model will be realized.
Fig. 2, Fig. 3, Fig. 4 have showed specific embodiment of the utility model, and it is finished by hydraulic ram.As Fig. 2, shown in Figure 3, offer a groove at clump weight 2 bottom midways location, slide rail 3 on two is housed in it, be fixed on the clump weight 2, also can directly cast them as a whole.On car body 1, correspondence is equipped with two glidepaths 4, and last slide rail 3, glidepath 4 cooperatively interact, between the two slidably.In the middle part of clump weight 2 and car body 1, hydraulic ram 5 has been installed, these hydraulic ram 5 cylinder ends are fixed on the car body 1, and rod end and clump weight 2 are hinged.When hydraulic ram 5 piston rods stretch out, move behind the clump weight 2; Otherwise, clump weight 2 reaches.
As shown in Figure 4, the front and back position that moves at clump weight 2 is arranged with upper limit block 6 and lower limit block 7, can be loaded on respectively on clump weight 2 and the glidepath 4.When clump weight 2 moves to end position, can touch mutually with two blocks, do not deviate from slideway to guarantee clump weight 2, play the security insurance effect, also can protect hydraulic ram 5 simultaneously, be unlikely being subjected to excessive impact tension.
The utility model can operate simultaneously by manual control and automatic guidance, and it is manually controlled is to realize by electric switch and electromagnetic valve, by stretching of operating personal direct control hydraulic ram 5, and clump weight 2 is moved forward and backward.Automatic guidance is the lift heavy tilting moment that detects car load by electric-control system, and when meeting or exceeding prescribed limit values, electric-control system sends corresponding electric signal, and clump weight 2 is moved under the drive of hydraulic ram 5.
Claims (4)
