Abstract

The utility model relates to the improvement of a running mechanism of a lath extruder. The utility model is characterized in that a front wheel adopts a universal wheel 11 which is provided with a fixing plate 7; a pair of waist circular holes 10 is arranged on the universal wheel 11; the corresponding positions of a carrier bar 1 are provided with a pair of screw holes; screws 9 and a spring 16 and a washer which are matched the screws 9 are screwed in the screw holes; the fixing plate 7 is locked and fixed by the washer 8 and the screws passing through the waist circular holes; the carrier bar and the lateral surface of a wheel carrier 11 are tightly compressed by the left lateral surface of the fixing plate 7 to cause the wheel carrier and the carrier bar to be correspondingly fixed; nuts are loosened to lift the fixing plate to be disengaged from the contact of the lateral surface of the wheel carrier, and the wheel carrier can rotate freely.

Description

Walking of batten extruder and guiding mechanism

The utility model relates to building material machinery, particularly a kind of improved walking mechanism of batten extruder of making batten.

Batten is popularized gradually as the building non-bearing wallboard and is used, and makes the mechanical and few of batten, and the walking mechanism of the batten machine that uses is but fixed at present, i.e. can only be during its operation along the trapped orbit straightaway, and very inconvenience of transition after operation finishes.Therefore people just are provided with a universal wheel in batten machine the place ahead, by the leading screw rotation batten machine are risen after operation finishes, and universal wheel contacts to earth, and road wheel is liftoff, so that clever the living of batten cut to.But exist stressed excessively in actual use, the flimsy shortcoming of universal wheel uses operation also inconvenient simultaneously.

The purpose of this utility model is exactly to solve stressed bad, the awkward defective of directive wheel in the prior art and a kind of new guiding walking mechanism of skill meter.

To achieve these goals, the utility model has adopted following technical proposals:

The carrier bar of batten extruder is provided with a pair of front-wheel and trailing wheel, the wheel carrier of trailing wheel and carrier bar fixed connection, the wheel carrier that it is characterized in that each front-wheel is provided with axis, carrier bar is provided with corresponding axis hole and dead eye, the axis root is equipped with plane bearing and is installed in the lower bearing hole of carrier bar, axis passes behind the axis hole its top and journal bearing is housed and is loaded in the upper shaft hole of carrier bar, axis upper end is associated with an end cap and locking nut thereof, and it is corresponding and leave the gap with carrier bar that end cap inner ring and journal bearing contact cooperation, outer ring; Other is provided with a fixed head, its one side is provided with concave surface, which is provided with a pair of microscler oval hole, carrier bar is provided with corresponding screw, be screwed into a screw in each screw, its middle part is with spring and packing ring, screw after passing the oval hole of fixed head is locked it, rely on fixed head plane and carrier bar side and wheel carrier contacts side surfaces spacing, wheel carrier and carrier bar are fixed, unclamp screw fixed head is climbed away the wheel carrier side in the oval hole length, tighten screw than the time and make that fixed head is unlikely to be fallen, then wheel carrier can freely rotate.Another kind of scheme is the hinged a pair of ratchet that has spanner on the carrier bar, connect a torsion spring on the pawl axis, fixed head is provided with a pair of corresponding breach, when fixed head upwards rises, its lower end breaks away from wheel carrier side, when the upper end breach surpasses ratchet, ratchet snaps in above-mentioned breach the fixed head location can not be fallen under the effect of torsion spring.

Owing to adopted technique scheme, two front-wheels are simultaneously stressed, and stressing conditions is greatly improved, and greatly improve service life; The guiding because front-wheel itself walking is held concurrently again makes simple in structurely, and the cost reduction is manipulated more flexible simultaneously.

In order to describe the utility model in further detail, following routine accompanying drawing provides a most preferred embodiment of the present utility model.

Description of drawings:

Fig. 1 is carrier bar of the present utility model and connection front and back wheel schematic diagram thereon;

Fig. 2 is that Figure 1A-A is to cutaway view.

As shown in Figure 1, pair of rear wheels is fixed on carrier bar 1 left end, a pair of front-wheel is connected in carrier bar 1 right-hand member, concrete draw bail as shown in Figure 2, wheel carrier 11 tops of front-wheel are provided with an axis 4, the axis root has shoulder 12, there is screw thread the upper end, carrier bar is provided with the lower bearing hole, axis hole and upper bearing (metal) hole, axis root shoulder place is fitted with plane bearing 13, from under pack into the lower bearing hole, its top was equipped with journal bearing 14 after axis passed axis hole, journal bearing is loaded on again in the upper bearing (metal) hole, and axis top is provided with an end cap 6, and its inner ring contacts with journal bearing, the outer ring is corresponding with carrier bar and leave the gap, axis upper end threaded portion is associated with nut 5 and is used to lock end cap 6, makes axis with respect to the carrier bar axial restraint, circumferentially freely rotate.Fixed head 7 profiles are square plate, its width is corresponding with wheel carrier 11, there is concave surface at fixed head 7 left surfaces middle part, the microscler oval hole 10 that wherein is provided with two symmetries is (as Fig. 1, shown in Figure 2), corresponding position is provided with a pair of corresponding screw on the carrier bar, be screwed into screw 9 in the screw, the screw middle part is with spring 16 and packing ring 8, they are arranged in the concave surface and the carrier bar counterbore 15 of fixed head, screw 9 passes 10 backs, oval hole and is connected by itself and packing ring 8 lockings, rely on fixed head left surface 17 (non-concave parts) to contact simultaneously and press carrier bar 1 and wheel carrier 11 sides, wheel carrier 11 relative carrier bars 1 are fixed; Unclamp screw 9 and rise fixed heads 7, make its lower end break away from wheel carrier side (can screw this moment screw 9 make fixed head is unlikely to be fallen), wheel carrier is free to rotate.Better scheme is the ratchet that has spanner 2 in hinged two symmetries in carrier bar side, be associated with torsion spring on the jointed shaft of ratchet 2, the fixed head both ends of the surface are provided with a pair of corresponding breach 3 and cooperate with ratchet 2, promptly when the fixed head rising, its lower end breaks away from wheel carrier, when breach 3 is crossed ratchet 2, under the effect of torsion spring, ratchet 2 snaps in the breach 3 fixed head is fixed, and wheel carrier is rotatable; Manually break into two with one's hands ratchet then fixed head fall.
