Description
Technical Field
The utility model relates to a hoist pulley technical field, in particular to hoist pulley convenient to dismouting.
Background
The crane pulley is the fixed pulley of hook group cooperation work, is fixed in structurally, forms by a plurality of fixed pulley and movable pulley combination, and it both can be laborsaving can change the effect direction of force again, and current crane pulley weak point lies in: 1. simple structure need use instruments such as sleeve pipe, bar copper during the installation, and even power is strikeed and just can be installed on the center pin, need use during the dismantlement to draw instruments such as horse to adopt and demolish it, take trouble hard, 2, fixed stability inadequately, long-time wearing and tearing lead to appearing the gap between installation hole and the center pin, 3, can't know its rotation state, for this, we provide a crane pulley of the dismouting of being convenient for.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide a crane pulley which is easy to assemble and disassemble, and which can effectively solve the problems of the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a hoist pulley convenient to dismouting, includes pulley plate, installation hole and strengthening rib, the installation hole has been seted up to pulley plate one end, the screw is installed through the mounting groove in installation hole both sides and installation hole both ends are installed through the thread groove and are installed the jackscrew, the welding has seted up the reservation hole between strengthening rib and the strengthening rib between installation hole and the pulley plate, the indicator has been seted up at the pulley plate both ends.
Further, the number of the reinforcing ribs and the preformed holes is multiple.
Further, one end of the screw rod is located outside the mounting hole.
Furthermore, the outer surface of the pulley plate is sprayed with an anticorrosive coating which is made of silicon carbide metal anticorrosive paint.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. through setting up the hob, the personnel pass through the installation hole cover with the pulley sheave on the center pin, and the hob of installation hole both sides is rotated simultaneously to the use tool, drives the pulley sheave and removes, makes it install to the center pin on, otherwise, when dismantling, the while antiport hob drives the pulley sheave and removes, makes it break away from on the center pin.
2. Through setting up the preformed hole, personnel are installing the pulley sheave at the center pin after, and the jackscrew is rotated to the use tool, makes it withstand the center pin, can fix the pulley sheave on the center pin, makes it difficult not hard up, drops.
3. Through setting up the indicateing arm, can follow its rotation when the pulley sheaves rotates, make things convenient for personnel to know the pulley sheaves pivoted condition.

In the figure: 1. a pulley plate; 2. mounting holes; 3. reinforcing ribs; 4. reserving a hole; 5. a screw rod; 6. carrying out top thread; 7. an indicator mark; 8. and (4) an anticorrosive layer.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-3, a hoist pulley convenient to dismouting, includes pulley disc 1, installation hole 2 and strengthening rib 3, installation hole 2 has been seted up to pulley disc 1 one end, installation hole 2 both sides are installed hob 5 and are installed 2 both ends in hole and install jackscrew 6 through the thread groove through the mounting groove, the welding has between installation hole 2 and the pulley disc 1 strengthening rib 3 and has seted up preformed hole 4 between the strengthening rib 3, indicator 7 has been seted up at pulley disc 1 both ends.
Wherein, the quantity of strengthening rib 3 and preformed hole 4 is a plurality of.
In this embodiment, as shown in fig. 1, the plurality of reinforcing ribs 3 can effectively improve the overall strength of the pulley sheave 1, and the plurality of preformed holes 4 can effectively reduce the weight of the pulley sheave 1.
Wherein, one end of the screw rod 5 is positioned outside the mounting hole 2.
In this embodiment, as shown in fig. 1, one end of the screw rod 5 is located outside the mounting hole 2, which is convenient for a person to use a tool to rotate the screw rod 5.
Wherein, the pulley disc 1 surface spray has anticorrosive coating 8 and anticorrosive coating 8 is for carborundum metal anticorrosive paint to make.
In this embodiment, as shown in fig. 3, the corrosion-resistant layer 8 made of the silicon carbide metal corrosion-resistant paint can effectively prevent the pulley plate 1 from rusting and corroding, and avoids influencing the rotation of the pulley plate 1.
It should be noted that the utility model relates to a crane pulley convenient for disassembly and assembly, when in operation, a worker sleeves a pulley plate 1 on a central shaft through an installation hole 2, the worker uses a tool to rotate a screw rod 5, the screw rod 5 rotates to drive the pulley plate 1 to move, thereby being installed on the central shaft, after the installation is in place, the worker uses the tool to rotate a jackscrew 6 to jack the central shaft, and fix the pulley plate 1 after the installation, when in disassembly, the worker uses the tool to reversely rotate the screw rod 5 to drive the pulley plate 1 to move until the pulley plate 1 is separated from the central shaft, the disassembly and assembly are convenient and quick, a plurality of reinforcing ribs 3 can effectively improve the overall strength of the pulley plate 1, a plurality of reserved holes 4 can effectively reduce the weight of the pulley plate 1, an indicator 7 can rotate along with the pulley plate 1 when the pulley plate 1 rotates, the worker can conveniently know the rotation state of the pulley plate 1, an anticorrosive coating 8 made of, can effectively prevent the pulley plate 1 from rusting and corroding and avoid influencing the rotation of the pulley plate 1.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
