Description

Lowering or hoisting gear

Technical field

The utility model is related to construction equipment field, and in particular, it is related to a kind of lowering or hoisting gear.

Background technology

Among construction, lift undertakes emphatically as material and personnel's vertical transport and the main tool of conveying The conveying task wanted.Because the complete sets of basic equipment facility of construction building does not have enough time also completing, thus above and below the lift during, In order to maintain the driving power supply of supply, electricity long in tow is needed along the building hoist above and below guide rail bracket or elevator drives body Cable, and the length of cable directly determines the straight-line displacement of lift highly.Due to unit length cable weight Through very big, and the story height constructed is higher, and therefore, lift or its driving body pull one section of longer cable, are spinning out Cable own wt it is larger in the case of, not only increase lifting difficulty, while being also unfavorable for safety, easily cause cable Fracture or winding accident, so as to trigger quality accident and interrupt constructing operation.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of lowering or hoisting gear, can effectively it subtract Light drag cable line lifts the influence of performance to lowering or hoisting gear, reduces because of the fault rate that cable breakage or winding trigger.

To achieve the above object, the utility model provides following technical scheme：A kind of lowering or hoisting gear, including guide rail bracket, Cage, the shock mount installed in guide rail bracket bottom moved up and down on guide rail bracket and along guide rail bracket, in guide rail bracket and Provided with cable saddle, along the spaced apart some cable guard rings of guide rail bracket short transverse, along guide rail bracket short transverse between cage The cable coaster of slip, fixed cable arm；The cable guard ring includes support arm, and one end of the support arm is provided with entirety and is in The guard ring of U-shaped, the U-shaped mouth two ends of guard ring are vertically close on the side wall of support arm, and guard ring is in integrally " Jie " shape, branch with support arm Passage is formed between brace and guard ring, guard ring includes the curve bend at U-shaped mouth two ends, and two curve bends are symmetrical arranged, two arcs Opening is left between shape bend pipe.

By using above-mentioned technical proposal, cable is led to from the bottom of guide rail bracket along guide rail at fixed cable arm, then Draw and be wrapped on cable coaster from fixed cable arm again, then led to by cable coaster on the cable saddle on cage, finally Cable is connected to power with the drive mechanism on cage.Cable sequentially passes through cable saddle, cable guard ring, cable coaster and consolidated Determine cable arm so that cable is locked, it is to avoid outwards rock and cause winding.Cable coaster is equivalent to movable pulley, cable saddle The half of cable and cable coaster gross weight is only equivalent to the tractive force that cable is provided, shadow of the cable to cage is greatly reduced Ring.Meanwhile, when cage rises, cable coaster rises under the lift power effect of cable along guide rail bracket；When cage declines, electricity Cable coaster declines under self gravitation effect along guide rail bracket so that cable is constantly in exceptionally straight state, it is to avoid cable is because of relaxation Bending is knotted or wound.And cable guard ring can not only by cable it is spacing live, and its opening can facilitate cable through being limited System is in cable guard ring

Preferably, the end top of the curve bend is horizontally disposed the closed component for preventing that cable from deviating from.

By using above-mentioned technical proposal, further prevent cable from deviating from.

Preferably, the closed component include be fixed on curve bend end connecting plate two and with the company of connecting plate two The rubber slab connect.

By using above-mentioned technical proposal, rubber slab can not only play restriction effect to cable, also, by cable When piercing into cable guard ring, due to the elasticity that rubber slab has, its operation is very convenient.

Preferably, be provided with the connecting plate two on nail, the rubber slab be provided with it is corresponding with the nail Perforation, by bolt through nail and perforation attaching nut rubber slab and connecting plate two are connected.

It is convenient that rubber slab is connected on connecting plate two by using above-mentioned technical proposal.

Preferably, the lower section of the rubber slab, which is provided with correspondence bolt position on backing plate, backing plate, is provided with nail, the end of bolt Fixed by packing ring and nut, rubber slab is gripped by backing plate and connecting plate two.

By using above-mentioned technical proposal so that the installation of rubber slab is more consolidated.

Preferably, the rubber slab of two curve bend ends is staggered.

By using above-mentioned technical proposal so that two rubber slabs can be overlapping, so that opening be blocked completely.

In summary, the utility model has the advantages that compared to prior art：

1st, position-limiting action is played to cable, prevents the cable pulled is rocked to guide rail bracket from winding；

2nd, the part of composition can be made into standard component, produce in batches, and cost is low；

3rd, simple in construction, onsite application is easy for installation.
