Description
Technical field
The utility model relates to a kind of Forklift mast apparatus.
Background technology
External sebific duct assembly pulley is all adopted in the high-pressure work oil pipe of empty container piling crane and the transmission of cable.During the operation of working space,, need be elevated to twenties meters high at the harbour etc., make the part working tubing and the cable that are used for suspender to fix because the stroke of suspender is bigger.When Forklift is travelling, turns, starts, stopping and door frame when waving, working tubing and cable can produce significantly swing, and working tubing and cable are easy to be hung on the framing member of some protrusions on the door frame like this.Under this situation,, can cause the damage of high-pressure work oil pipe and cable if continue operation.Must be limited in the sebific duct roller owing to high-pressure work oil pipe (that is to say sebific duct) again, thus the predetermincd tension that sebific duct need be certain, make sebific duct bear pulling force, pulling force will increase when sebific duct rocks, and reduce the life-span of sebific duct.Be the generation of prevention malignant event, external sebific duct assembly pulley need increase overhanging baffle plate, blocks sebific duct and rocks; Employing sebific duct shock absorber reduces the axial tension of sebific duct, but effect is also not satisfactory.
CN200620069229 discloses a kind of scheme, wherein sebific duct is placed in the door frame, and outer mast frame protection sebific duct in allowing or not sebific duct be hung up by lamp bracket and retaining pipe support.Sebific duct still has very long one section can not fix, and still exists sebific duct to rock, and can't eliminate the suffered longitudinal pulling force of sebific duct, and the sebific duct life-span is shorter.
The utility model content
The utility model proposes a kind of new mast apparatus that is used for Forklift, it can guarantee that sebific duct and/or cable do not rock, and can reduce the pulling force of sebific duct, the functional reliability that improves sebific duct and/or cable service life and guarantee Forklift.
The utility model provides such solution, a kind of mast apparatus that is used for Forklift, comprise: door frame, chain and the cable and the high-pressure rubber pipe that are used for the Forklift suspender, wherein, described door frame comprises outer mast and the inner upright mounting that moves with respect to described outer mast, and described chain is wrapped on the sprocket wheel that is positioned at described inner upright mounting inboard, it is characterized in that, also be provided with the pipe clamp that is fixed on the described chain, described pipe clamp clamps described high-pressure rubber pipe and/or described cable.
The utility model considers that chain and cable, high-pressure rubber pipe stroke are consistent; propose the suffered longitudinal force of sebific duct is unloaded on the chain; thereby utilizing chain to rock minimum characteristic can protect sebific duct and/or cable not to rock; further chain is protected, improved sebific duct, cable service life greatly by pipe clamp.In addition owing to need not to be stretched in the sebific duct roller, therefore can reduce the pulling force of sebific duct, but also can further reduce the suffered pulling force of sebific duct by the length that strengthens sebific duct, the functional reliability that improves sebific duct and/or cable service life and guarantee the Forklift suspender.
According to an improvement project of the present utility model, described sebific duct is settled in described pipe clamp with longitudinal movement.Can eliminate the suffered external pulling force of sebific duct fully, and can not rock so that sebific duct has the surplus of length direction.Simultaneously can reduce the harm that hydraulic efficiency impact brings.
Preferably, the quantity of pipe clamp is a plurality of, and described a plurality of pipe clamps are fixed on the described chain in a longitudinal direction with predetermined interval.
Preferably, described pipe clamp removably is fixed on the described chain.
Preferably, described sebific duct and/or described cable clamp are settled in described pipe clamp concurrently, make the operation of sebific duct and cable smooth and easy.
The advantage of scheme of the present utility model is when door frame hoists; because sebific duct and cable is limited by chain and the protection of pipe clamp; difficult generation is rocked; thereby be difficult for causing sebific duct and cable flexing scratch to hang up and tensile phenomenon; reduced the sebific duct fault rate; increased the service life of sebific duct, further also can be by making the length of sebific duct surplus be arranged and eliminate the suffered external pulling force of sebific duct fully.Because the utility model adopts portal-framed structure simple, cancel baffle plate, sebific duct pulley yoke, promoted support, fixed support and sebific duct buffer gear, reduced the produce and market cost; And it is easy to maintenance.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described further
Fig. 1 is the structural representation of mast apparatus;
Fig. 2,3,5 is a partial enlarged drawing;
Fig. 4 is the pipe clamp structure scheme drawing;
Fig. 6 is the chain scheme drawing.
The specific embodiment
Fig. 1 is the structural representation that is used for mast apparatus, as shown in Figure 1, mast apparatus comprises: outer mast 3 and inner upright mounting 2, chain 5 and the cable 6 and the high-pressure rubber pipe 7 that move with respect to described outer mast 3, and chain 5 is wrapped on the sprocket wheel 8, and described sprocket wheel 8 is positioned at the inboard of described inner upright mounting 2.Inner upright mounting 2 is by elevating ram 9 liftings, and suspender 1 is elevated to the higher position, and the fuel feeding oil return sebific duct 7 and the cable 6 that need to be used for suspender 1 fixedly avoid its generation to rock.
In the utility model, as shown in Figure 1, the fixed form of cable 6 and high-pressure rubber pipe 7 can be passed to its longitudinal loading on the chain 5, thus since chain 5 to be subjected to the action of gravity rolling momentum of suspender 1 less, thereby rocking of sebific duct 7 and/or cable 6 is also less.The transmission of chain 5 this longitudinal loadings realizes that by pipe clamp 4 pipe clamp 4 has been fixed on the chain 5, and high-pressure rubber pipe 7 and/or cable 6 are clamped.Shown in Fig. 2,3,5 partial enlarged drawing.
Because the movement travel of chain 5 is the same with sebific duct 7, be that an end is fixed on that the other end is fixed on the suspender 1 on the outer mast 3, therefore, can limit rocking of sebific duct 7 by the pipe clamp 4 that is fixed on the chain 5.Preferably, the quantity of pipe clamp 4 is a plurality of, and described a plurality of pipe clamps 4 are fixed on the described chain 5 in a longitudinal direction with predetermined interval.
In specific embodiment according to Fig. 1, consider that chain 5 is crooked by sprocket wheel 8 places, sebific duct 7 is different with the bending spring of chain 5, if sebific duct 7 is extremely fixing with chain 5, sebific duct 7 will elongate.Be subjected to longitudinal pulling force for fear of sebific duct 7, so sebific duct can not be fixing too tight by pipe clamp 4, so used pipe clamp 4 as shown in Figure 4, this pipe clamp 4 can make sebific duct 7 vertically move freely, the surplus of the length of sebific duct 7 can be strengthened like this, the longitudinal pulling force that sebific duct 7 is subjected to will be significantly reduced.
In addition, described as shown in Figure 4 sebific duct 7 and/or described cable 6 are settled in described pipe clamp 4 concurrently.In addition, pipe clamp 4 removably is fixed on the chain 5, as shown in Figure 4, utilizes bolt 10 that pipe clamp 4 is fixed on the chain 5.
