Abstract
The present invention relates to a kind of external clamping angle steel fixed pulleys, including upper clamp plate, lower clamp plate and fixed pulley, upper clamp plate and the L-shaped vertical connection of lower clamp plate, fixed pulley is mounted on lower clamp plate, the wheel shaft axle center of fixed pulley and lower clamp plate sustained height, the wheel shaft of fixed pulley is vertical with upper clamp plate, and the wheel shaft both ends of fixed pulley have reinforcing rib, and reinforcing rib is connect with upper clamp plate.The present invention is convenient to mount and dismount, connects simply, and when work, and the axle center of pulley and clamped angle steel are the same as high, it has been lifted working depth, so that the rope binding height around single-sheaved block is increased, convenient for the operation of the higher slinging work of binding point, improve work efficiency.
Description
Technical field
The present invention relates to a kind of external clamping angle steel fixed pulley, the high-altitude suitable for overhead power line angle steel tower is applied
Work industry, belongs to electric power application field.
Background technique
Fixed pulley in existing machinery operation, be responsible in the service work of transmission line of electricity lifting, transmitting Work tool or
The effect of various types of materials.But under specific condition, because of the relative position of its work, work on the spot can be unfavorable for.For example, replacing
When line insulator string, for the insulator chain of the top conducting wire, it is connect and is played with fixed pulley suspension hook by steel wire loop
Hoisting point position will be too low, keeps more changing jobs for insulator chain more laborious.In addition, being easy to swing when fixed pulley works, to construction
Operation affects.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provides a kind of external clamping angle steel fixed pulley, i.e.,
The working depth for having raised fixed pulley in turn avoids swing when fixed pulley work.
Technical scheme is as follows:
External clamping angle steel fixed pulley, including upper clamp plate, lower clamp plate and fixed pulley, upper clamp plate and lower clamp plate is L-shaped vertically connects
It connects, fixed pulley is mounted on lower clamp plate, the wheel shaft axle center of fixed pulley and lower clamp plate sustained height, the wheel shaft and upper clamp plate of fixed pulley
Vertically, the wheel shaft both ends of fixed pulley have reinforcing rib, and reinforcing rib is connect with upper clamp plate.
The upper clamp plate and lower clamp plate is equipped with long lumbar hole, and screw rod passes through long lumbar hole and is fixed on upper clamp plate and lower clamp plate
On angle steel, gasket is equipped between screw rod and long lumbar hole.
The lower clamp plate is equipped with via hole, and via hole is set to the two sides of fixed pulley.
The reinforcing rib uses hollow design.
Advantages of the present invention effect is as follows:
The present invention is convenient to mount and dismount, connects simply, and when work, the job platform (axle center) of fixed pulley and clamped angle steel are same
Height has been lifted working depth, so that the rope binding height around fixed pulley is increased, convenient for the higher lifting work of binding point
The operation of work, improves work efficiency.And by the clamping of upper and lower plywoods, the swing of fixed pulley is avoided, in addition, outer clip
Formula angle steel fixed pulley can also spin upside down installation, flexible multi-purpose.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of upper and lower plywoods of the present invention.
In figure, 1, upper clamp plate, 2, fixed pulley, 3, reinforcing rib, 4, via hole, 5, lower clamp plate, 6, long lumbar hole.
Specific embodiment
Referring to the drawings, detailed description of the present invention specific structure and mode of operation.
Embodiment
As shown, external clamping angle steel fixed pulley, including upper clamp plate 1, lower clamp plate 5 and fixed pulley 2,1 He of upper clamp plate
The L-shaped vertical connection of lower clamp plate 5, fixed pulley 2 are mounted on lower clamp plate 5, the wheel shaft axle center of fixed pulley and lower clamp plate sustained height,
It has been lifted the working depth of fixed pulley.The wheel shaft of fixed pulley is vertical with upper clamp plate, and the wheel shaft both ends of fixed pulley have reinforcing rib 3,
Reinforcing rib is connect with upper clamp plate, and reinforcing rib can upgrade heavy load, maximum load 1000kg, and make to determine cunning by reinforcing rib
For wheel by the two-sided fixation of upper and lower plywoods, stress is secured.
The upper clamp plate and lower clamp plate is equipped with long lumbar hole 6, installation site can be adjusted according to specific angle steel size, through moving
Dynamic adjustment is applicable to width 100mm angle steel below, and can spin upside down installation, flexible multi-purpose, and screw rod passes through long lumbar hole
Upper clamp plate and lower clamp plate are fixed on angle steel, gasket is equipped between screw rod and long lumbar hole, gasket becomes after can avoid clamping plate fastening
Shape.
The lower clamp plate is equipped with via hole 4, and via hole is set to the two sides of fixed pulley, it is possible to provide ties up for complementary
Bundle or carry.
The reinforcing rib, using hollow design, to mitigate weight.
When the present invention installs, it can be fixed on the angle steel that gauge size is ∠ 50-100mm, it should be by upper clamp plate, lower clamp plate point
It is not placed in the inside and outside side of angle steel, upper and lower two clamping plate is connected by long lumbar hole, screw rod, installs gasket additional between two clamping plates and screw rod.
When work, first should according to the width of angle steel, using screw rod by long lumbar hole by upper clamp plate, that lower clamp plate is mounted on angle steel is suitable
Operating position, rope bypass fixed pulley race, can carry out lifting or lift work after having bound hanging object.Via hole can be used to
Bolt hangs Work tool and other items, assists fixed pulley work.
Design parameter of the present invention: upper and lower plywoods wide 150mm, long 200mm；Overall weight about 4kg；Fixed pulley diameter 80mm,
Maximum hoisting weight 1000kg.
