Description
Technical field
The utility model relates to a kind of door frame that connects lift truck attachment and built-in oil circuit, is applicable to fork truck.
Background technology
Common forklift accessory oil circuit adopts plug-in tube coiling appts, by being arranged on accessory on the sebific duct shaft clevis support body of both sides tube coiling apptss the inside of outer mast upper end.But in the time that fork is got higher goods, tube coiling appts easily blocks operator's sight line, impact operation sight line.Tube coiling appts is positioned at outer mast both sides, and misoperation may bump with the goods stacked on work-yard, cause potential safety hazard, and the price of tube coiling appts is also more expensive.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide the door frame of a kind of connection lift truck attachment simple in structure, easy for installation, lower-cost and built-in oil circuit, to reduce the impact on operator's sight line.
The technical scheme that the utility model adopts is: a kind of door frame that connects lift truck attachment and built-in oil circuit, there is outer mast, inner upright mounting and crotch body, wherein inner upright mounting is moving up and down is installed in outer mast, same moving up and down being installed on inner upright mounting of crotch body, it is characterized in that: on described outer mast, fix three steel oil pipes and tetrad steel oil pipe, corresponding two steel oil pipes are provided with two pulleys at inner upright mounting top, and pulley is fixed on inner upright mounting top through bearing pin; Corresponding three steel oil pipes and tetrad steel oil pipe are installed respectively and are fixed three and join oil clot and tetrad is joined oil clot on crotch body; Described three steel oil pipe one end three oil pipe I connect forklift multi-way valve, and the other end connects three and joins oil clot after three oil pipe II are walked around the corresponding pulley of institute; Described tetrad steel oil pipe one end connects forklift multi-way valve through tetrad oil pipe I, and the other end connects tetrad and joins oil clot after tetrad oil pipe II is walked around the corresponding pulley of institute.
Two pulleys are arranged about inner upright mounting Central Symmetry.
The beneficial effects of the utility model are: tube coiling appts plug-in left and right is designed to built-in connection oil circuit by the utility model.In fork truck work, avoid human element, cause goods on oil circuit and work-yard to bump.When fork is got higher goods, avoid blocking operator's sight line, improved the safety of oil circuit and fork truck, connection structure is simple, there is no complex parts, has therefore improved product life.The utility model is simple in structure, easy for installation and cost is lower.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment is a kind of door frame that connects lift truck attachment and built-in oil circuit, comprise outer mast A, inner upright mounting B and crotch body C, wherein inner upright mounting B is installed in outer mast A, and outer mast A moves up and down relatively, crotch body C is installed in inner upright mounting B, and (lift truck attachment is arranged on crotch body C), and outer mast A moves up and down relatively.In the present embodiment, on outer mast A, fix three steel oil pipes 3 and tetrad steel oil pipe 4, two steel oil pipe upper ends about outer mast A Central Symmetry.The upper end of corresponding two steel oil pipes is provided with two pulleys 7 at inner upright mounting B top, and pulley is fixedly installed on inner upright mounting B through bearing pin 8.Corresponding three steel oil pipes 3 and tetrad steel oil pipe 4 are fixed three and are joined oil clot 9 and tetrad is joined oil clot 10 installing respectively on (crotch body) C.Three steel oil pipe 3 lower end three oil pipe I 2 connect forklift multi-way valve, and upper end connects three and joins oil clot 9 after three oil pipe II 5 are walked around the corresponding pulley 7 of institute.Tetrad steel oil pipe 4 lower ends connect forklift multi-way valve through tetrad oil pipe I 1, and upper end connects tetrad and joins oil clot 10 after tetrad oil pipe II 6 is walked around the corresponding pulley of institute.
In the present embodiment, according to the wide door frame characteristics of motion of fork truck two-stage, outer mast A is fixed static state, and crotch body C moves in inner upright mounting B, and speed is v; The relative outer mast A motion of inner upright mounting B, speed is v; Therefore crotch body C speed relative and outer mast A is 2v.
Pulley 7 is fixed on inner upright mounting, is a kind of movable pulley structure, and three oil pipe II 5 and tetrad oil pipe II 6 are all around on pulley 7.According to the principle of movable pulley, inner upright mounting B top sheave 7 has along the straight-line motion of outer mast and the rotation of self.Rely on pulley 7 to rotate, crotch body C upper three joins oil clot 9 and tetrad, and to join relative and speed outer mast of oil clot 10 be 2v.Thereby can obtain the kinematic velocity of oil pipe and the kinematic velocity of door frame is consistent.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation made, change and add or replace, all should belong to protection domain of the present utility model.
