Abstract
The utility model discloses a hanger rod-pulley device. The hanger rod-pulley device comprises a pulley (1) and a clamp plate (2), wherein the pulley (1) is connected with the clamp plate (2) rotatably; wherein the upper part of the clamp plate (2) is circular; the upper end and the lower end of the clamp plate (2) are provided with two openings; and a bolt (3), a nut (4) and a cotter pin (5) are arranged at each of the openings. The diameter of circumference formed by the clamp plate (2) is 70 mm; and the distance between the bolts (3) arranged at the upper opening and the lower opening of the clamp plate (2) is 120 mm. By adopting the hanger rod-pulley provided by the utility model, the service life can be prolonged, the hanger rod-pulley device is simple and convenient to install, and raw materials are saved.
Description
Technical field
The utility model relates to a kind of pulley, just relates to a kind of suspension rod pulley specifically.
Background technology
Differential pulley commonly used in the factory also is a kind of assembly pulley.Be used widely in the assembly pulley mechanical field.Pulley has two kinds: fixed pulley and movable pulley are combined into assembly pulley.Fixed pulley essence is bascule, not laborsaving also leicht fallen D/A, but can change force direction. the characteristics of fixed pulley are to come the drag hook sign indicating number not laborsaving through fixed pulley.Through or through fixed pulley, reading be the same.Thus it is clear that, do not use fixed pulley laborsaving but can change the direction of power.Under many situation, the direction that changes power can bring convenience to work.Fixed pulley essence is a bascule, and power L1, resistance L2 arm all equal the pulley radius.Also can draw not labour-saving conclusion of fixed pulley according to lever equilibrium condition.Movable pulley essence is that power arm is the lever of two times of resistance arms, 1 times of distance of the many expenses of 1/2 power of economizing. the characteristics of movable pulley are to use movable pulley can economize half power, take distance.This is that the hook sign indicating number is played by two sections ropes because when using movable pulley, and every section rope is only born the half the of hook code weight.Though use movable pulley to economize power, the distance that power moves has promptly been taken distance greater than the distance that the hook sign indicating number raises.Assembly pulley: the assembly pulley of forming with movable pulley by fixed pulley; Not only laborsaving but also can change the direction of power. assembly pulley is with several sections ropes object that plays; The power of mentioning used for object is exactly the part of gross weight. and the free end of rope is walked around one section of the calculation of movable pulley; Though and that just do not calculated that walks around fixed pulley uses assembly pulley to economize power, has taken distance, the distance that the distance that power moves moves greater than weight.
Summary of the invention
The purpose of the utility model provides a kind of in-problem a kind of suspension rod pulley in the prior art that overcomes.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
A kind of suspension rod pulley; Comprise pulley, clamping plate; Said pulley and clamping plate are rotatably connected, and the top of said clamping plate is rounded and have two openings, at said opening part bolt, nut and spring cotter is installed; The diameter of the formed circumference of described clamping plate is 70mm, and the distance between the bolt that has two opening parts installations up and down of described clamping plate is 120mm.
The effect and the benefit of the utility model are:
Adopt the suspension rod pulley of the utility model, can improve service life, simple installation is saved raw MAT'L.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model.
Specific embodiment:
Be described in detail the most preferred embodiment that the utility model is described below in conjunction with technical scheme and accompanying drawing.
A kind of suspension rod pulley gear comprises pulley 1, clamping plate 2, and said pulley 1 is rotatably connected with clamping plate 2, and the top of said clamping plate 2 is rounded and have two openings, at said opening part bolt 3, nut 4 and spring cotter 5 is installed.The diameter of described clamping plate 2 formed circumference is 70mm, and the distance between the bolt 3 that has two opening parts installations up and down of described clamping plate 2 is 120mm.Bolt adopts M16 * 35 in the utility model, and nut adopts M16 in the utility model, and the utility model split shed pin adopts 5 * 15.
Claims (1)
1. suspension rod pulley gear; Comprise pulley (1), clamping plate (2); Said pulley (1) is rotatably connected with clamping plate (2), and the top of said clamping plate (2) is rounded and having two openings up and down, at said opening part bolt (3), nut (4) and spring cotter (5) is installed; It is characterized in that: the diameter of the formed circumference of described clamping plate (2) is 70mm, and the distance between the bolt (3) that has two opening parts installations up and down of described clamping plate (2) is 120mm.
