Description

Technical Field

[0001] This utility model relates to the field of wiring technology for drop weight testing machines, and in particular to a wiring device for drop weight testing machines. Background Technology

[0002] The drop hammer impact test for ferritic steel is a crucial step in the inspection of metallic materials. With the increasing demand for drop hammer testing machines for ferritic steel, the rational design of its related components is becoming increasingly important. The testing standard GB / T6803-2008 provides detailed specifications for all aspects of the drop hammer test method for the non-plastic transformation temperature of ferritic steel, including scope, principle, terminology and definitions, specimens, testing equipment and instruments, testing requirements, testing procedures, evaluation of test results, and test reports.

[0003] The lifting system of the equipment mainly consists of two parts: the lifting device and the hammer body. It adopts the traction electromagnet to release the hammer and requires a 220V power supply. In addition, a proximity switch is installed between the lifting device and the hammer body. Therefore, the installation of the wires becomes a key component of the drop hammer test. Under the traditional wiring method, the wires are exposed to the air, which is prone to problems such as wire insulation wear and safety hazards. To address these issues, we propose a wiring device for the drop hammer test machine. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wiring device for a drop hammer test machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wiring device for a drop weight testing machine includes a base, with fixed frames fixed on both sides of the upper end of the base. A top plate is installed on the upper end of the fixed frames. A crossbeam is slidably connected between the top plate and the base. The crossbeam has an opening, in which an auxiliary traction mechanism and a clamping mechanism are installed. A current collector is installed on one side of the crossbeam via a current collector clip. An insulating box is installed on one side of the fixed frames. Insulating box covers are installed on both sides of the insulating box. A sliding groove is installed inside the insulating box. A spring carbon brush is installed on the sliding groove. A guide pulley is installed on the spring carbon brush and is engaged in the sliding groove. A photoelectric switch is installed on one side of the lower end of the crossbeam.

[0007] Preferably, two guide rods are fixed between the opposite sidewalls of the top plate and the base, and copper sleeves are fixedly fitted on both sides of the crossbeam, with one guide rod on the same side passing through one copper sleeve on the same side.

[0008] Preferably, the auxiliary traction mechanism includes a chain seat installed in the opening, the upper end of which is connected to a chain, the chain passing through the crossbeam and extending to the upper end of the crossbeam.

[0009] Preferably, the clamping mechanism includes a traction electromagnet installed on one side of the opening, and a hook is installed at the lower end of the crossbeam. One end of the hook is connected to the traction electromagnet via a clamping plate.

[0010] Preferably, multiple retaining clips are fixed at equal intervals around the perimeter of the insulating box, and one end of each retaining clip is fixed to the bottom plate of the insulating box, which is installed on one side of the fixed frame.

[0011] In this invention, a safety mechanism of self-locking upon power failure and hammer release upon power success is adopted. The V on the traction electromagnet includes two power lines (positive and negative), and the proximity switch includes two power lines (positive and negative) and one signal line, for a total of five lines. A six-pole sliding groove is selected. The specific implementation steps are as follows:

[0012] 1. Current collector installation: The current collector is installed on the side of the crossbeam using the current collector clip. Connect the five power lines of the lifting device to the current collector terminals respectively, and ensure proper insulation.

[0013] 2. Slide rail fixing: Use clamps to fix the slide rail and insulation box to the side of the fixing frame;

[0014] 3. Conductivity: The current collector is equipped with four guide pulleys and six spring carbon brushes. The spring carbon brushes contact the copper plate in the slide groove, thereby achieving the conductivity function.

[0015] 4. Insulation treatment: An insulation box is installed at one end of the sliding rail. The insulation box, the insulation box cover plate and the insulation box bottom plate are combined to tightly wrap the exposed end of the sliding rail. The power cord is led out through the hole on the insulation box cover plate.

[0016] The clamping mechanism is used to clamp the test object. The test is conducted by connecting the traction lifting mechanism and the auxiliary traction mechanism with a chain at the upper end of the top plate.

[0017] This utility model has the following advantages:

[0018] 1. This wiring device uses a combination of components such as current collectors, wire guides and insulation boxes to arrange and protect wires in a reasonable manner. The wire guides provide a relatively enclosed space for the wires, avoiding direct exposure, reducing the risk of wire insulation wear, and greatly improving the safety of the equipment.

[0019] 2. The combination of the insulation box, insulation box cover, and insulation box base plate tightly wraps the exposed end of the sliding wire groove to prevent leakage, further ensuring the safety of operators and the stable operation of the equipment;

[0020] 3. The selection of a six-pole sliding groove can meet the requirements of the circuit layout, ensure the normal operation of the lifting system, and provide stable power support for the drop hammer test;

[0021] In summary, this utility model rationally arranges and protects the wires. The sliding groove provides a relatively enclosed space for the wires, avoiding direct exposure, reducing the risk of wire insulation wear, greatly improving equipment safety, preventing leakage, and further ensuring the safety of operators and the stable operation of the equipment. At the same time, it eliminates the need for complex wiring connections and debugging processes, thus improving the working efficiency of the equipment. Attached Figure Description

The guide pulley 11 is engaged in the sliding groove 8, ensuring the stable sliding of the current collector 10 on the sliding groove 8.

[0027] A photoelectric switch 7 is installed on one side of the lower end of the crossbeam 1. The photoelectric switch 7 can monitor relevant parameters during the test in real time, such as the position and motion state of the object, and convert this information into electrical signals and transmit them to the control system so that the control system can make corresponding decisions and adjustments.
