                                              作者:管理員    發布于:2019-09-02 15:24:17    文字:【】【】【
                                              First, use:
                                              The concrete anchor rails used in China's railways have the characteristics of high strength, reliable use, low cost, convenient construction and easy maintenance. However, it must be ensured that the good quality of the sulfur anchoring can achieve satisfactory results. The detector is a testing device for testing the quality of sulfur anchoring of concrete sleepers on site. It is applicable to the inspection and construction quality acceptance of single pillows that have been anchored in the new line engineering, rail-row base, line overhaul and maintenance, and the management unit and related laboratories. Used to supervise the quality of sulfur anchoring.
                                              Second, the technical parameters of the railway casing drawing instrument:

                                              2, display unit: direct reading KN
                                              3, accuracy level: ≤ standard level
                                              4, storage, viewing, clearing function
                                              Hollow cylinder
                                              1, rated tensile force (T)
                                              30
                                              2. Nominal oil pressure (MPa)
                                              60
                                              3, the maximum stroke of the piston (mm)

                                              4, the center hole diameter (mm)
                                              45
                                              5, weight (Kg)
                                              12
                                              Third, the railway casing drawing instrument structure
                                              The railway casing drawing instrument is a pulling tool for the railway cement sleeper thread spikes.
                                              It consists of a base, a pull rod, an elastic cone, a tightening rod, a lifting nut, a snap ring and a thrust bearing. The pull rod is a hollow rod with external thread and is processed with a tapered surface matched with the elastic cone head. The tapered portion of the elastic cone head is also processed with a plurality of elastic grooves, and the convex surface of the base and the rail of the rail are avoided on the base. The bottom is machined with a bevel and the screw can be removed. When using, screw the rod into the base and place it on the sleeper, so that the threaded spike penetrates into it. Screw the elastic cone to the thread of the spike with the tightening rod. After tightening, remove the tightening rod to prevent the tightening rod from being too high. Invade the traffic limit. Then, the lifting nut is twisted to screw out the pulling rod. During the screwing process, the elastic cone head clamps the threaded spike under the action of the taper cone surface, and moves with the pulling rod in the direction of screwing out. The base is pressed against the sleeper, so that the bond between the spikes anchored into the sleeper portion and the anchored sulfur mortar is broken and the spike is pulled out.
                                              Fourth, the detection method of railway casing drawing instrument:
                                              The detection of the railway casing puller is carried out on the already anchored sleepers.
                                              1. Install the detector:
                                              Screw the tie rod together with the beam onto the spike to be inspected, place the post on the shoulder of the sleeper and connect it to the adjustment nut.
                                              2. Place the pressure pump on the sleeper platform, rotate the adjustment nut or the pressure pump pressure handle to make the top of the pressure pump contact the instrument main beam (this fashion is not forceful), and keep the beam at a basic level.
                                              3. Install the meter on the top of the instrument's force beam, which can be used.
