Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, if there are first and second descriptions for distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the precedence of the indicated technical features.

In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

The existing hydraulic disc brake device consists of three parts: the brake system comprises an actuating mechanism, a hydraulic station and an operating platform which are used for braking and are connected by hydraulic pipelines. The hydraulic station is a power source and provides necessary hydraulic power for the actuating mechanism; the operation table is a power control link; the brake executing mechanism is a brake executing part and consists of three parts, namely a brake caliper, a caliper frame and a brake disc, wherein the brake caliper is divided into a normally open type working caliper and a normally closed type safety caliper.

The working principle is as follows: when pressure oil P is input into the normally open single-action oil cylinder, thrust F is generated, and the magnitude of the thrust F is F = P × A, wherein A is the area of a piston. The pushing force F pushes a piston rod of the oil cylinder to extend out; meanwhile, the pushing force F is transmitted to the end of the brake block through the lever when the brake block contacts the brake disc, so that the pushing force F acts on the brake disc to generate positive pressure N. Under the action of the positive pressure N, a friction force, namely a braking force, is generated. Because the braking force and the oil pressure P are in a proportional change relationship, when the oil pressure P reaches a certain value, the brake disc is in a full braking state; when the oil pressure P =0, the lever returns to the original position under the action of the return spring, so that the brake block is separated from the brake disc, and the working caliper is in a completely released state. The working principle of the safety gear is opposite to that of the working gear. When the oil pressure P =0 in the normally closed single-acting oil cylinder, the built-in disc spring transmits force to the brake block through the two levers to act on the brake disc, so that positive pressure N is generated to realize braking; when the oil pressure P in the oil cylinder is not equal to 0, the oil pressure overcomes the force of the disc spring to compress the disc spring when the oil pressure is available, and the brake is released through the lever.

Before transformation: the operation platform comprises a single brake valve component, a parking valve component, a control valve group, a pipeline, a pressure gauge and the like. When the brake is operated, the brake valve is controlled by the brake lever, the brake valve is a manual proportional pressure reducing valve, the output pressure of the valve changes proportionally along with the pulling of the brake lever, and the output pressure of the brake valve changes from 0 to the maximum system pressure corresponding to different positions where the brake lever is located. The larger the pulling angle of the brake crank is, the larger the pressure of the oil cylinder of the working caliper is. The brake crank is pushed to the original position, the valve output pressure is 0, and the working pliers are released. The emergency brake is controlled by an emergency button valve which is a manual reversing air valve and controls an air control reversing valve. When the emergency brake button is pressed, the air source is cut off, and the pneumatic control reversing valve spring is reset, so that the safety tongs are braked; meanwhile, the hydraulic control reversing valve reverses due to the pressure loss of the control end, and pressure oil directly enters the working tongs, so that the braking of the working tongs is realized. Namely: all the brake calipers brake, and emergency braking is realized.

After transformation: the auxiliary driller operating table is added in the original driller room, and the added part comprises: emergency brake button valve, partial hydraulic pipeline, etc. The hydraulic pipeline is connected with an actuating mechanism which can simultaneously act on the brake of the working tongs, the pipeline of the actuating mechanism is connected with an oil pressure gauge through a tee joint, and when the actuating mechanism acts, the pressure gauge can display the pressure of the current working tongs in real time. The emergency brake button valve is a manual reversing air valve, and in order to ensure the safety of equipment, the emergency brake button valve is connected with the original operating platform emergency brake valve in series through a PU pipe, and the brake can be released only when the main driver operating platform and the auxiliary driver operating platform open the two emergency brake valves simultaneously.
