Abstract
The utility model discloses a limit controller which comprises an electric appliance box, an input shaft and a rocker arm, wherein the input shaft and the rocker arm are arranged on the outer side of the electric appliance box. One end of the rocker arm is fixedly connected with the input shaft and the other end of the rocker arm is an insulation arm. The limit controller is used for conducting insulation protection to one end of the rocker arm. The limit controller is not as sharp as a metal sheet so that electric cables are not easy to scratch. Even though the electric cables appear electricity leakage conditions, the limit controller can be protected from be damaged for the reason that the insulation protection is achieved and is safe to use. Insulation materials which are good in insulating property and low in cost can be used as the insulation materials. The production cost is not increased.
Description
Technical field
The utility model relates to a kind of limit controller, specifically, relates to the good limit controller of a kind of safety performance.
Background technology
The large-scale handling equipment in harbour adopt the power supply mode of cable drum or reel more, electric cable run-in synchronism in the assurance, in order to prevent the wrong volume of upper electric cable, to climb the improper displacement of cable, and cause the cable can not normal operation, What is more can cause the accident, need to pull dolly leading of cable limit controller is installed, yet the rocking arm of limit controller mostly is steel-sheet type at present, contact with cable easily and scratch cable, and steel rocking arm conduction, contact the conduction accident that easily occurs with high-tension cable, thereby cause the damage of cable.
Based on this, how to invent a kind of safe limit controller, when can reduce production costs, improve its insulativity and safety, can satisfy preferably the equipment operating needs, be the problem that the utility model mainly solves.
Summary of the invention
The utility model uses unsafe problem for the rocking arm that solves existing limit controller scratches cable easily, and a kind of limit controller is provided, and its rocking arm one end has been carried out insulation protection, is not easy to scratch cable, uses safety.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of limit controller comprises electrical appliance kit, is arranged on input shaft and the rocking arm in the described electrical appliance kit outside, and described rocking arm one end is captiveed joint with input shaft, and an other end is insulation arm.
Further, described rocking arm one end is the Metallic rod that has mounting hole, and an other end cover has insulation sleeve, and described input shaft is connected with rocking arm by mounting hole.
Further again, an other end of described rocking arm is with externally threaded projection, and described insulation sleeve is with the negative thread that matches with described outside thread.
Wherein, described insulation sleeve can be the nylon insulation sleeve.
Described insulation sleeve can be plastic insulation covering.
Described insulation sleeve can be rubber insulation sleeve.
Described insulation sleeve can be wooden insulation sleeve.
Compared with prior art; advantage of the present utility model and good effect are: limit controller of the present utility model; by its rocking arm one end has been carried out insulation protection; and do not have sheetmetal so sharp, be not easy to scratch cable, even if cable outlet electric leakage situation; limit controller is carried out insulation protection not to be damaged; use safety, the insulation material can adopt good insulation preformance, nylon that cost is low, plastics, rubber, the material such as wooden, does not increase cost of manufacture.
After reading by reference to the accompanying drawings the detailed description of the utility model embodiment, other characteristics of the present utility model and advantage will become clearer.
Description of drawings
Fig. 1 is a kind of example structure scheme drawing of the limit controller that proposes of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in more detail.
Embodiment one, and referring to shown in Figure 1, the limit controller of present embodiment comprises electrical appliance kit 1, input shaft 2 and rocking arm 3, and described input shaft 2 is arranged on described electrical appliance kit 1 outside, and described rocking arm 3 one ends are captiveed joint with input shaft, and an other end is insulation arm.The limit controller of present embodiment in use; wrong volume, the cable of climbing the improper displacement of generation such as cable touch insulation arm one end of rocking arm 3; it is rotated; rocking arm 3 and then with the rotation of driven input shaft 2, give the control unit incoming signal in the electrical appliance kit 1, and then can take certain measures such as power-off protection; and insulation arm does not have sheetmetal so sharp; be not easy to scratch cable, even if cable outlet electric leakage situation is carried out insulation protection to limit controller and is not damaged.
Concrete described rocking arm 3 one ends are the Metallic rod 31 that has mounting hole in the present embodiment, and an other end 32 covers have insulation sleeve 4, and described input shaft 2 is connected convenient disassembly by mounting hole with rocking arm 3.
Further, in order to make things convenient for the installation of rocking arm 3 and insulation sleeve 4, an other end 32 of described rocking arm 3 is with externally threaded projection, and described insulation sleeve 4 is with the negative thread that matches with described outside thread, when mounted described projection is screwed in insulation sleeve 4 and get final product, the convenient installation and replacing insulation sleeve 4
Wherein, described insulation sleeve 4 preferred low nylon insulation sleeve or the plastic insulation coverings of cost that adopt also can be rubber insulation sleeve or wooden insulation sleeve etc., and such insulation sleeve appearance is round and smooth, can be to the cable injury.
The limit controller of present embodiment can well be protected cable winding.This is spacing to be directly used in the wrong volume of electric cable on the high pressure, climb cable, the reel cable falls improper displacement detecting such as groove, need not add other links, it is highly sensitive, reliability is strong, can be widely used in machine high pressure reel on the heavy mechanical equipment, the improper displacement detecting of hose coiling mechanism cable.By its rocking arm one end has been carried out insulation protection; be not easy to scratch cable; even if cable outlet electric leakage situation; limit controller is carried out insulation protection not to be damaged; use safety; the insulation material can adopt good insulation preformance, nylon that cost is low, plastics, rubber, the material such as wooden, does not increase cost of manufacture.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
