Description

The utility model relates to lifting and transport equipment, namely to winding devices, in particular to cable drums, and can be used in mobile equipment such as lifting, mining, and special equipment.

Due to the high power required for this type of equipment, for example, an excavator, gantry cranes, etc., most manufacturers use drive mechanisms that run on liquid fuels, which leads to significant energy consumption and serious environmental pollution. Therefore, at present, the types of equipment that run on electricity are widely used. These devices require long cables to provide a range of operating conditions. To move long-distance cables when dragging cables along the ground, they are easily damaged and pose a hazard to the work environment. Thus, an urgent problem is the use of a winding mechanism, for example, for a cable reel, which can prevent damage to cables, facilitate the movement, winding and unwinding of various cables. The purpose of the winding device (cable drum) is to protect the cable from damage and wear during the movement of the machine (crane, truck, excavator, car pushers, etc.).

Known options for using a spiral cable reel with the traditional method is the fastening of the cable reel on 2 supports, when the rotation is transmitted to the gear, rigidly fixed on the drum. As an example - cable drums of gantry cranes (see link):

Disadvantages of the traditional method of attaching a cable drum to two supports: the need to install a shaft rigidly fixed to the winding drum with two radial bearings (traditional design), the need to manufacture a separate gear ring, shaft and bearing assemblies - structurally and technologically difficult and costly, the need to adjust the alignment of the gear ring and bearings with a shaft, which is technologically difficult, with the wear of the ring gear during operation, difficulties with replacement, the need to have special equipment and technologies during manufacture and operation, which reduces the overall reliability of the winding device.

During the operation of the winding mechanism, the gear rim and radial bearings are exposed to the greatest load and wear, which reduces the service life and reliability of the winding device and the cable drum as a whole, while replacing this unit is technologically difficult and costly, and as a result, low maintainability, low durability of the winding device ...

To eliminate the aforementioned drawbacks, the design of the winding device is proposed, in which the gear wheel and the gear wheel of the winding device are replaced by a functional unit of the support-rotary unit, made as a standard module. The slewing bearing unit (hereinafter referred to as the OPU) combines two functional elements - a gear wheel and a bearing. OCPs as a standard module are serially produced by machine-building enterprises all over the world in a large assortment and work as devices for transmitting the rotation of lifting machines with a vertical axis of rotation.

Thus, the winding device comprises a pivot assembly made as a standard module, consisting of a gear wheel and a bearing, while the slewing bearing assembly is an easily replaceable standard module. This achieves an increase in the maintainability, durability of the winding device, simplification of the design, and an increase in the efficiency of production and operation of the winding device.

The technical result is an increase in the durability and maintainability of the winding device by simplifying the design.

The technical result is achieved due to the design of a winding device containing a frame on which an engine with a drive gear is installed, characterized in that the drive gear is installed with the possibility of transmitting torque to a rotary bearing unit containing a bearing and a gear wheel, the gear rim of which is rigidly fixed to the reel of the winding device, and the base of the pivoting unit is rigidly fixed by fasteners to the frame of the reeling unit, while the pivoting unit is a standard functional unit. As a special case, with a wide winding device, the spool axis is equipped with an additional support.

The essence of the technical solution is illustrated by the images in FIG. 1-8.

An example of implementation.

The winding device consists of a frame 1, on which an engine 5 with a driving gear is installed 4. The driving gear 4 transmits torque to the rotary bearing unit 2, the gear rim of which is rigidly fixed to the winding drum 6, and the base of the rotary bearing unit 2 is rigidly fixed by fasteners elements 3 to the frame 1 of the winding device. The rotation of the drum 6 is transmitted from the engine 5 through the drive gear 4 to the ring gear and then to the winding drum.

The slewing bearing unit 2 as a functional unit combines two constituent elements - a gear wheel and a bearing. As a standard module, slewing rings are serially produced by machine-building enterprises all over the world in a large assortment and are used to transmit the rotation of lifting machines with a vertical axis of rotation.

A winding device with an OPU in the design of a winding drum with a narrow bobbin (Fig. 1, 2). When using winding drums with a wide bobbin, it is required to install an additional bearing support 7. Two types of designs with an additional support - on one side with a support (Fig. 3, 4) and from different sides (Fig. 5, 6).

A conventional winding device is shown in FIG. 4, with a winding drum supported by a shaft and two bearing assemblies.

The use of an OPU in a winding device provides the following advantages:

1. Significant structural simplification of the rotation transmission unit. There is no need to install a shaft rigidly fixed to the winding drum with two radial bearings (traditional design).

2. Simplification of the manufacturing technology of the winding device due to the absence of the need to manufacture a separate gear rim, shaft and bearing assemblies and replace them with a serial OPU.

3. The assembly of the winding device is simplified, since there is no need to adjust the alignment of the gear rim and bearings with the shaft (in the OPU they are combined into one unit and are set by the manufacturer).

4. If the ring gear is worn out during operation, the replacement does not cause additional problems for consumers.

5. General conclusion. The use of a winding device with an OPU instead of individually manufactured parts provides the following advantages: simplified design, reduced production time for winding devices, no need for special equipment and technologies, increased maintainability, increased overall reliability of the device due to the use of serial modules of the OPU and, as a result, makes a winding a device with an OPU is more cost-effective in production and operation.
