Description

Technical Field

[0001] The utility model belongs to the technical field of generator sets, and in particular relates to a cable sheath rack used for generator sets. Background Art

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow or fuel combustion into mechanical energy and transmits it to the generator, which then converts it into electrical energy and outputs it to electrical equipment for use.

[0003] When the generator set is in use, the electric energy is usually transmitted by cables. In order to lay and fix the cables, a cable sheath rack is usually used. The structure of the traditional cable sheath rack is relatively simple, mainly including a mounting frame, on which a casing or a cable fixing ring is installed, and the cable is passed through the casing or the cable fixing ring.

[0004] However, the above-mentioned cable sheath rack has poor practicality. Although it can achieve the purpose of laying out and fixing cables, when encountering strong winds or strong airflows, the cables are easily swayed by the wind. During the swaying process, the sheath of the cable will rub against the cable sheath rack, and then wear and twist will occur, causing damage to the cable and affecting the use of the cable.

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are described in detail as follows:

[0021] See also Figure 1 The cable sheath rack for a generator set of the utility model includes a general mounting seat 4, on which a hinged mounting member 6 is fixedly connected, on which a support swing seat 2 is hingedly installed through a pin shaft, and a guide support rod 1 is installed at the end of the support swing seat 2 away from the hinge point, and the lower end of the guide support rod 1 is in rolling contact with the general mounting seat 4; in this embodiment, a bull's eye ball is fixedly connected to the bottom of the guide support rod 1 and is in rolling contact with the top surface of the general mounting seat 4.

[0022] Since the support swing seat 2 and the hinged mounting member 6 are hingedly connected, the support swing seat 2 will swing around the hinge point between it and the hinged mounting member 6 under the action of wind or airflow. In order to reduce the amplitude of the above-mentioned swinging process, multiple groups of elastic buffer devices 3 are installed between the support swing seat 2 and the general mounting seat 4 and are respectively arranged on both sides of the support swing seat 2. For further reference, Figure 2 In this embodiment, the elastic buffer device 3 includes a buffer seat structure fixed on the main mounting seat 4, a buffer guide rod 3-2 is slidably inserted into the buffer seat structure and is laterally arranged, and the inner end of the buffer guide rod 3-2 is pivotally connected to the support swing seat 2; a buffer spring 3-4 is sleeved on the buffer guide rod 3-2 and is in elastic contact with the buffer seat structure.

This embodiment also includes a first movable clamping wheel 10 whose lateral position is adjustable corresponding to the two groups of first stationary clamping wheels 12, and a second movable clamping wheel 16 whose lateral position is adjustable corresponding to the two groups of second stationary clamping wheels 15. The above-mentioned first movable clamping wheel 10 and the second movable clamping wheel 16 are located on opposite sides of the movable clamping wheel, wherein the first movable clamping wheel 10 is arranged in cooperation with the two groups of first stationary clamping wheels 12, and the second movable clamping wheel 16 is arranged in cooperation with the two groups of second stationary clamping wheels 15.

[0026] In order to achieve the purpose of adjusting the two sets of first movable clamping wheels 10 and second movable clamping wheels 16, the present embodiment further includes two sets of driving racks 14 which are slidably connected and arranged opposite to each other on the clamping wheel mounting seat 11. The outer ends of the two sets of driving racks 14 are respectively connected to the first movable clamping wheel 10 and the second movable clamping wheel 16, so that the first movable clamping wheel 10 and the second movable clamping wheel 16 can be driven to move by the lateral movement of the driving racks 14. In order to improve the stability of the movement process of the first movable clamping wheel 10 and the second movable clamping wheel 16, as shown in FIG. Figure 1 and Figure 3As shown, two sets of rack guides 13 arranged opposite to each other are fixedly connected to the clamping wheel mounting seat 11, and two sets of driving racks 14 are respectively slidably inserted into the slide grooves provided on the two sets of rack guides 13.
