Therefore, need provide a kind of engineering mechanical device and roll wheel assembly thereof, to address the above problem.
The model utility content
The technical problem that the utility model mainly solves provides a kind of engineering mechanical device and roll wheel assembly thereof, can prevent that rope and roller break away from, and avoid having an accident.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of roll wheel assembly is provided, and wherein, roll wheel assembly comprises: scaffold, roller, rope and escapement.Roller rotates and is installed on the scaffold.Rope is set around on the roller, to be led by roller.Escapement is installed on the scaffold, passes through and limit the cornerite of rope pair roller to allow rope.
Wherein, be arranged at intervals with first through hole and second through hole on the escapement, rope is located in first through hole before on being set around roller, and is located in after on being set around roller in second through hole, and the diameter of first through hole and second through hole is greater than the diameter of rope.
Wherein, the spacing between first through hole and second through hole equals rope and is set around parallel distance on the roller.
Wherein, roll wheel assembly further comprises fitting seat, and scaffold is fixed on the fitting seat.
Wherein, scaffold comprises two mounting plates and an installation shaft, and two mounting plates relatively secured in parallel are installed on the fitting seat, and installation shaft fixedly is arranged between two mounting plates, and roller is arranged between two mounting plates and rotates and is installed on the installation shaft.
Wherein, escapement is fixedly set between two mounting plates, and the mounting point of escapement is positioned at the extended side of rope.
Wherein, the outer circumferential face of roller is provided with groove, and groove is used for holding rope.
Wherein, the degree of depth of groove is greater than or equal to the diameter of rope.
Wherein, the width of groove is greater than or equal to the diameter of rope.
For solving the problems of the technologies described above, another technological scheme that the utility model adopts is: a kind of engineering mechanical device is provided, and this project machinery comprises above-mentioned any one described roll wheel assembly.
The beneficial effects of the utility model are: be different from the situation of prior art, the utility model limits the cornerite of rope pair roller by escapement is set, and can prevent that rope and roller break away from, and avoid having an accident.
Description of drawings
Fig. 1 is the plan view of the preferred embodiment of roll wheel assembly of the present utility model;
Fig. 2 is the plan view of roll wheel assembly among Fig. 1;
Fig. 3 is the structural representation of escapement of the present utility model.
Embodiment
See also Fig. 1, Fig. 1 is the plan view of the preferred embodiment of roll wheel assembly of the present utility model.In the present embodiment, roll wheel assembly 1 comprises fitting seat 10, scaffold 11, roller 12, rope 13 and escapement 14.
See also Fig. 2, Fig. 2 is the plan view of roll wheel assembly among Fig. 1.In the present embodiment, scaffold 11 is fixed on the fitting seat 10.Scaffold 11 is preferably and comprises two mounting plates 111,112 and one installation shaft 113.Two mounting plates 111,112 relatively secured in parallel is on fitting seat 10, and installation shaft 113 fixedly is arranged between two mounting plates 111,112, and installation shaft 113 and two mounting plates 111,112 plate face all are preferably vertical setting.Fitting seat 10 generally is fixed on the precalculated position of engineering mechanical device.In other embodiments, roll wheel assembly 1 also can not comprise fitting seat 10, and scaffold 11 is directly fixed on the engineering mechanical device, also can not comprise fitting seat 10 when perhaps roll wheel assembly 1 is as movable pulley.
See also Fig. 3, Fig. 3 is the structural representation of escapement of the present utility model.In the present embodiment, escapement 14 is the metal bar of cuboid.And in other embodiments, can the shape of disconnecting prevention structure 14 be changed, be oval-shaped metal bar etc. for the cross section for example, the utility model is not done restriction in shape at escapement 14.In other embodiments, but escapement 14 also can be the nylon monomer-cast nylon bar of selflubricating.Be arranged at intervals with first through hole 141 and second through hole 142 on the escapement 14.Rope 13 is located in first through hole 141 before on being set around roller 12, and is located in after on being set around roller 12 in second through hole 142.And the diameter of first through hole 141 and second through hole 142 is greater than the diameter of rope 13.Wherein, the spacing between first through hole 141 and second through hole 142 equals rope 13 and is set around parallel distance on the roller 12, so that rope 13 is before being set around on the roller 12 and be arranged in parallel afterwards.By the way, the cornerite that escapement 14 can stationary rope 13 pair rollers 12, when rope 13 does not stress or pretension when insufficient, rope 13 pair rollers 12 cornerites can not become greatly, and rope 13 is unlikely to come off.
It should be noted that in the present embodiment, escapement 14 be preferably through hole is set thereon mode with stationary rope 13 pair rollers 12 cornerites, in other embodiments, escapement 14 is stationary rope 13 pair rollers 12 cornerites by other means also.
The utility model has also disclosed a kind of engineering mechanical device, and it comprises the above-mentioned described roll wheel assembly of any embodiment.
