Abstract

The utility model discloses a liftable steering fixed pulley, include the triangle-shaped support body that comprises horizontal pole, pole setting and bracing link to each other, the bottom of pole setting pass through the fixed plate and fix on ground the front end of the horizontal pole of triangle-shaped support body open and to have a quad slit, square clamping screw's lower part pass the quad slit and link to each other with the outer lane of bearing is fixed, the roof of the U-shaped support of a fixed pulley passes through the inner circle of connecting rod and bearing and fixes continuously square clamping screw on the spacing hole that has a plurality of axes to set up along the horizontal direction of spaced apart from top to bottom, a location bolt has been inserted in the spacing hole of setting for position department, the location bolt support make square clamping screw fix in the position department of setting for the height on the roof of horizontal pole. The pulley can enable the target object to quickly reach the designated height and the designated direction.

Description

Liftable steering fixed pulley

Technical Field

The utility model relates to a fixed pulley especially relates to liftable steering fixed pulley.

Background

The traditional fixed pulley is a fixed device, and the motion trail of a target object is simply changed by changing the direction of force. The target object cannot be quickly reached to the designated height and the designated direction, so that the working efficiency is low.

Disclosure of Invention

An object of the utility model is to overcome prior art's shortcoming, provide one kind and provide and to make the target object arrive appointed height and appointed direction fast, improved production efficiency's liftable steering fixed pulley simultaneously.

In order to solve the technical problem who exists among the current fixed pulley, the utility model discloses a following technical scheme:

the utility model discloses a liftable steering fixed pulley, include the triangle-shaped support body that comprises horizontal pole, pole setting and bracing link to each other, the bottom of pole setting pass through the fixed plate and fix on ground the front end of the horizontal pole of triangle-shaped support body open and to have a quad slit, square clamping screw's lower part pass the quad slit and link to each other with the outer lane of bearing is fixed, the roof of the U-shaped support of a fixed pulley passes through the inner circle of connecting rod and bearing and fixes continuously square clamping screw on the spacing hole that has a plurality of axes to set up along the horizontal direction of upper and lower spaced apart, a location bolt has been inserted in the spacing hole of setting for position department, the location bolt support make square clamping screw fix in the position department of setting for the height on the roof of horizontal pole.

The utility model has the advantages that the structure is suitable for portable hoisting operation, and the existing fixed pulley is improved, thereby achieving the purpose of improving the production efficiency and enabling the target object to quickly reach the designated height and the designated direction.

Drawings

Fig. 1 is a schematic structural view of the liftable fixed pulley.

Detailed Description

The present invention is further described with reference to the accompanying drawings:

as shown in the attached drawings, the lifting and steering fixed pulley comprises a triangular frame body formed by connecting a cross rod 10, a vertical rod 8 and an inclined strut 9, wherein the bottom of the vertical rod 8 is fixed on the ground through a fixing plate 11.

The front end of a cross rod 10 of the triangular frame body is provided with a square hole (the square hole is used for ensuring that a fixing screw rod cannot rotate along with the movement of a target object and is provided with rotation by a bearing 6, so that the stability of the whole structure and the flexibility of pulley rotation are ensured), the lower part of a square fixing screw rod 1-1 penetrates through the square hole and is fixedly connected with the outer ring of the bearing 6, the top wall of a U-shaped support 2 of a fixed pulley 3 is fixedly connected with the inner ring of the bearing 6 through a connecting rod 1-2, a plurality of limiting holes 7 with axes arranged along the horizontal direction are arranged on the square fixing screw rod 1 at intervals from top to bottom, a positioning bolt 5 is inserted into the limiting hole at a set position, and the positioning bolt 5 is supported on the top wall of the cross rod 10 so that the square fixing screw rod 1 is fixed at the set height. In the figure 4 is the pulley shaft of the fixed pulley 3.

The bearing can make the fixed pulley turn to among this structure, has square opening on supporting the support body horizontal pole, guarantees that set screw can insert the horizontal pole opening, according to the spacing hole height of demand height adjustment set screw, inserts the location bolt.

The above examples are only used to illustrate the present invention, and the structure, material and connection of each component can be changed, and all the equivalent changes and improvements performed on the basis of the technology of the present invention should not be excluded from the protection scope of the present invention.

Claims

1. Liftable turn to fixed pulley includes the triangle-shaped support body that constitutes by horizontal pole, pole setting and bracing link to each other, the bottom of pole setting pass through the fixed plate and fix on ground its characterized in that: the front end of the cross rod of the triangular frame body is provided with a square hole, the lower part of a square fixing screw rod penetrates through the square hole and is fixedly connected with the outer ring of the bearing, the top wall of a U-shaped support of a fixed pulley is fixedly connected with the inner ring of the bearing through a connecting rod, the square fixing screw rod is provided with a plurality of limiting holes which are arranged along the horizontal direction at intervals from top to bottom, a positioning bolt is inserted into the limiting hole at the set position, and the positioning bolt is supported on the top wall of the cross rod to fix the square fixing screw rod at the set height.
