Detailed Description

It is noted that relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

The features and properties of the present invention are described in further detail below with reference to examples.

Referring to fig. 1-4, an electric hoist suitable for different working environments comprises an electric hoist body 11, wherein the electric hoist body 11 comprises all equipment meeting the normal operation of the electric hoist, such as a working cabinet, a power transmission and control system and the like; the upper part of the electric hoist body 11 is connected with a moving part 13 through a bracket 12, the moving part 13 is directly connected with a cross beam 15 above a factory in a hanging mode, and the moving part 13 can slide on the cross beam 15 in a manual operation mode; a traction rope 111 extends out of the lower part of the electric hoist body 11, and the lower part of the traction rope 111 is connected with a hook 14 through a fixed pulley 112; the hook 14 is moved up and down by the extension and contraction of the pulling rope 111.

In daily electric block's installation, it is all different to discover the crossbeam 15 design between a plurality of mills, and the crossbeam 15 that has some mills directly adopts the square steel to make, and the crossbeam 15 that has some mills directly adopts the round steel to make, and both do not adopt the installation dedicated electric block spout to be installed altogether electric block, consequently when needs install electric block in these two kinds of mills, still need install a spout altogether electric block normal operating specially, fairly inconvenient.

Therefore, the moving part 13 is designed to be three-in-one, in other words, three kinds of pulleys are designed and installed in the moving part 13 to meet different factory requirements; the moving part 13 comprises a first pulley block 131, a second pulley block 132 and a third pulley block 133; the first pulley block 131, the second pulley block 132 and the third pulley block 133 sequentially pass through the built-in shaft 121 from top to bottom and are mounted on the bracket 12.

The first pulley block 131 consists of two track pulleys in total to be matched with a special sliding groove of the electric hoist; the special sliding chute for the electric hoist is I-shaped; during installation, as shown in fig. 2, the two rail pulleys are arranged corresponding to the two sides of the chute special for the electric hoist, so that the first pulley block 131 is hung on the chute special for the electric hoist, and the installation is completed.

The second pulley block 132 is arranged below the first pulley block 131, and has a certain distance with the first pulley block 131, and the distance is such a size that the special chute for the electric hoist cannot contact with the second pulley block 132 after the first pulley block 131 is installed; the second pulley block 132 is composed of a plurality of cylindrical rollers, and circular baffles 1321 are arranged on two sides of each cylindrical roller; the device is used for being mounted on a cross beam 15 made of square steel; during installation, as shown in fig. 3, the second pulley block 132 is installed above the cross beam 15 made of square steel, and the circular baffles 1321 clamp the square steel, so that the second pulley block 132 is fixed in the horizontal direction, and the second pulley block 132 is prevented from turning on one side.

The third pulley block 133 is used in cooperation with the cross beam 15 made of round steel; the third pulley block 133 is composed of a plurality of U-shaped rollers; the third pulley block 133 is arranged below the second pulley block 132 and has a certain distance with the second pulley block 132, and the distance is such that the beam 15 does not contact with the third pulley block 133 after the second pulley block 132 is installed; during installation, as shown in fig. 4, the third pulley block 133 is only needed to be installed on the cross beam 15 made of round steel, and the groove on the third pulley block 133 is clamped with the cross beam 15, so that the installation of the electric hoist is completed.

Due to the design of the three groups of pulley blocks, the electric hoist can be directly used in a plurality of different working environments, and is quite convenient; when the pulley block is installed on the cross beam 15, the built-in shaft 121 can be taken down firstly, the pulley block is placed on the cross beam 15, and convenient installation is achieved by installing the built-in shaft 121.

The above-mentioned embodiments only express the specific embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for those skilled in the art, without departing from the technical idea of the present application, several changes and modifications can be made, which are all within the protection scope of the present application.
