Abstract
The utility model provides an improved structure of a forklift gantry, comprising an inner gantry, an outer gantry and a guide wheel device, wherein the inner gantry slidably arranged in the outer gantry; the guide wheel device comprises an outer ring, a plurality of pin rollers, an axle and an added axle seat; the upper end of the outer gantry is provided with an opening hole; the added axle seat is provided with a fixing hole corresponding to the axle and the added axle seat is detachably arranged on one side surface of the outer gantry far away from the inner gantry; one end of the axle penetrates through the opening hole of the outer gantry and the fixing hole of the added axle seat in sequence; each pin roller is rotatably arranged on the outer side wall of the circumference at the other end of the axle; and the inner side wall of the circumference of the outer ring is contacted with each pin roller and can rotate opposite to the pin roller. In the utility model, the axle which is originally welded at the upper end of the outer gantry is changed to be detachably arranged at the upper end of the outer gantry through the added axle sea, therefore the repair and detachment are easy and convenient.
Description
Technical field
The utility model relates to the fork truck field, more particularly relates to a kind of improvement structure of forklift door frame.
Background technology
Fork truck is the high-efficiency appliance of mechanized handling, stacking and short-distance transportation.Door frame in the fork truck is the major bearing structures of fork truck load-engaging device, gets the requirement of goods lifting altitude according to fork, and forklift door frame can be made two-stage or multistage, and common common fork truck adopts the two-stage door frame more.The two-stage door frame is made up of inner upright mounting and outer mast, inner upright mounting has roller, be embedded in the outer mast, can in outer mast, do upper and lower motion, outer mast top is provided with capstan, is used for when inner upright mounting rises, and the guiding inner upright mounting rises, guide wheel rotates along the guide rail in the inner upright mounting outside, can also play and accept the gravity that is subjected to the goods compressing from inner upright mounting.At present, the capstan on fork truck outer mast top is to be through a wheel shaft that is welded on the outer mast, because the wheel shaft weldering is extremely on outer mast, when capstan damaged, capstan was difficult to disassemble from wheel shaft, causes the difficulty of keeping in repair dismounting.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of improvement structure of forklift door frame, has solved the problem of prior art fork truck outer mast upper end capstan maintenance dismounting difficulty.
In order to achieve the above object, the utility model is by the following technical solutions: the improvement structure of forklift door frame, comprise inner upright mounting and outer mast, described inner upright mounting is located in the outer mast slidably, also include guide wheel device, described guide wheel device comprises the outer ring, a plurality of rollers, wheel shaft and wheel shaft add seat, described outer mast upper end is provided with a perforate, described wheel shaft adds seat and is provided with and the corresponding fixed orifice of wheel shaft, wheel shaft adds seat and is located at removably on the side of outer mast away from inner upright mounting, one end of wheel shaft is arranged in the perforate of outer mast and the fixed orifice that wheel shaft adds seat successively, described each roller is located on the periphery wall of the wheel shaft other end rotationally, the inside circumference wall of outer ring contacts with each roller, and can relatively rotate with each roller.
Further, described wheel shaft add the seat be fixedly arranged on the side of outer mast away from inner upright mounting by bolt.
The utility model compared with prior art, has following advantage: because simple and reasonable, original wheel shaft that is welded in the outer mast upper end is made into add seat by a wheel shaft wheel shaft is located at the outer mast upper end removably, having changed original technology wheel shaft can't disassemble from outer mast, causes the problem of maintenance dismounting inconvenience; The utility model, only needs bolt is screwed out owing to be by bolt wheel shaft to be added seat to be fixed on the outer mast when capstan damages, takes off wheel shaft and adds toilet and wheel shaft can be taken out from outer mast, and with regard to replaceable maintenance capstan, it is lighter, more convenient to keep in repair dismounting.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is that Fig. 1 is a right elevation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
With reference to figure 1, Fig. 2, the utility model embodiment discloses a kind of improvement structure of forklift door frame, comprise outer mast 1 and inner upright mounting 2, described inner upright mounting 2 is located in the outer mast 1 slidably, also include guide wheel device, described guide wheel device comprises outer ring 31, a plurality of rollers, wheel shaft 32 and wheel shaft add seat 33, described outer mast 1 upper end is provided with a perforate, described wheel shaft adds seat 33 and is provided with and wheel shaft 32 corresponding fixed orifices 331, wheel shaft adds seat 33 and is located at removably on the side of outer mast 1 away from inner upright mounting 2, perforate and wheel shaft that one end of wheel shaft 32 is arranged in outer mast 1 successively add on the fixed orifice 331 of seat 33, described each roller is located on the periphery wall of wheel shaft 32 other ends rotationally, the inside circumference wall of outer ring 31 contacts with each roller, and can relatively rotate with each roller.
It is one to have certain thickness oblong or pros open iron plate that above-mentioned wheel shaft adds seat 33, four angles of iron plate offer bolt hole 332, also be provided with cooresponding bolt hole on the outer mast 1, screw in cooresponding bolt hole 332 by bolt 4, wheel shaft is added seat 33 be fixedly arranged on outer mast 1 upper end, wheel shaft 32 also is fixedly arranged on the outer mast upper end simultaneously.When capstan damages, only need bolt 4 is screwed out, to take off wheel shaft and add seat 33 and just wheel shaft 32 can be taken out from outer mast 1, the maintenance dismounting is lighter, more convenient.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present invention that do not break away from appended claims and limited; can make various variations to the present invention in the form and details, be protection domain of the present utility model.
