The specific embodiment

By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification sheets.

Refer to accompanying drawing.Notice, appended graphic the illustrated structure of this specification sheets, ratio, size etc., equal contents in order to coordinate specification sheets to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Meanwhile, described in this specification sheets " on " side refers to the direction contrary with the action direction of gravity; D score side refers to the direction identical with the action direction of gravity; " front " side refers to the direction identical with the throughput direction of material; " afterwards ", side referred to the direction contrary with the throughput direction of material.

Fig. 2 is to the structural representation that Figure 5 shows that material-pulling device of the present utility model, and as shown in Figures 2 to 5, the material-pulling device that the utility model provides also comprises delivery track 4, lorry cylinder 1 and is connected in lorry 2 of lorry cylinder 1 etc.In order to simplify the structure of material-pulling device, the material-pulling device that the utility model provides has removed the devices such as shift fork cylinder 6 and associated gas circuit, circuit, the shift fork being installed on lorry 2 is the eccentric shift fork 3 of installing, shift fork 3 is installed in a rotating shaft 31 rotationally, the center of gravity of shift fork 3 is positioned at rotating shaft 31 belows, make shift fork 3 state of being kept upright under Action of Gravity Field, and the upper end of shift fork 3 is higher than the end face of delivery track 4.When the upper end of shift fork 3 is promoted forward along delivery track 4 by external force, shift fork 3 can turn to below the end face of delivery track 4.

In embodiment, the steel material being pushed by material-pulling device is square tube 5.In Fig. 2 to Fig. 4, the front line direction of square tube 5 on delivery track 4 is arrow indicated direction, and the initial condition of shift fork 3 is erectility.When square tube 5 is encountered upright shift fork 3, the thrust that shift fork 3 is subject to is forward overturn and is toppled over forward along the front line direction of square tube 5, and whole shift fork 3 is positioned at below the end face of delivery track 4 completely, and the center of gravity of shift fork 3 is elevated simultaneously.When square tube 5 is from shift fork 3 tops are passed through, thrust that shift fork 3 is subject to disappears, and under the effect of himself eccentric weight moment, turns back to again erectility.Now the piston rod of lorry cylinder 1 is released, and promotes lorry 2 and moves forward.Wheel 22 is housed on lorry 2, during lorry 2 operation, in the wheel track of wheel 22 below delivery track 4, rolls.Between the axletree of installing wheel 22 and lorry 2, there is no relative motion, shift fork 3 can directly be installed on axletree, and the rotating shaft 31 of shift fork 3 is exactly the axletree of lorry 2, and shift fork 3 can 31 rotate around the shaft.Shift fork 3 in erectility promotes square tube 5 and continues operation forward under the drive of lorry 2, until be pushed on packaging platform.After this, the piston rod of lorry cylinder 1 is regained, and pulls lorry 2 and shift fork to get back to initial position.

Shift fork 3 is subject to External Force Acting and will overturns, and for preventing that the antagonistic force that shift fork 3 in propelling movement process is subject to square tube 5 from turning over, is provided with the limiting stopper 21 coordinating with shift fork 3 on lorry 2.As shown in Figure 5, this limiting stopper 21 can be installed in the front portion of lorry 2, and the lower end of shift fork 3 is provided with a confined planes 32 forward, and when shift fork 3 is during in erectility, confined planes 32 and the limiting stopper 21 of shift fork 3 connect.Even if be therefore subject to the antagonistic force of square tube 5, also can not turn at the effect lower shift fork 3 of limiting stopper 21.

The material-pulling device that the utility model provides has replaced needing in prior art shift fork cylinder to control its shift fork upright or upset with eccentric shift fork, and without devices such as shift fork cylinder and relative gas circuit and circuit, the structure of whole material-pulling device is more simple; Shift fork is meeting Automatic-dumping under the pressure-acting of pushed product, and pressure can rely on the Action of Gravity Field adjustment of self to return erectility after disappearing, and has greatly simplified operating process, has improved production efficiency, has also eliminated the potential safety hazard causing because of complicated operation.

In sum, the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.

Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
