[0023] Application Overview:
[0024] With the development of electrified railways, steel pipe hard crossovers have been widely used as an important supporting device for the power supply of the contact network of electrified railways. The contact network steel pipe hard crossover is a contact network structure used in electrified railways, which can effectively provide support for the contact network components. It is a door-type structure composed of steel pipe hard crossbeams and steel pipe columns. The steel pipe hard crossbeams are assembled and welded by seamless steel pipes, connecting flanges and stiffening plates. The main welding seam type is fillet welds. The crossbeam is a triangular cross-section lattice steel pipe composite beam. The beam section is spliced by the middle section and the side section; flange connections are used between the beam sections and between the crossbeams and the pillars. The contact network steel pipe hard crossover has the following advantages: first, it has a simple structure, is easy to install, and has low maintenance costs; second, the steel pipe has good mechanical strength and corrosion resistance, and can adapt to various climatic conditions; third, the steel pipe hard crossover can improve the rigidity and stability of the contact network, reduce the fluctuation of the contact line, and improve the operating speed and safety. The contact network steel pipe hard crossover has been widely used in many high-speed railways and urban rail transit lines in my country, making important contributions to the development of my country's railway industry.
[0025] During the manufacturing process, the curved section of the middle beam of the steel tube rigid beam has a certain arch value. The arch is to prevent the middle beam from sagging too much (excessive deflection) during the installation process, so that the steel tube rigid beam can reach the horizontal position. The current test method for the arch value is to fix the middle beam on the jig, apply pressure to the middle part of the middle beam with a jack, and then overlap the two ends of the steel pipe with a line, and use a steel ruler to measure the height of the middle part of the middle beam. This method is not only time-consuming and labor-intensive, but may also cause the arch value to be too large or too small, affecting the quality and safety of the steel pipe.
[0026] Figure 1 The figure is a structural schematic diagram of a non-working state of an electric railway contact network steel pipe hard crossbeam arching measuring device provided by an embodiment of the utility model; Figure 2 The figure is a schematic structural diagram of an electrified railway contact network steel pipe hard crossbeam arch measuring device in a working state provided by an embodiment of the utility model.
[0027] like Figure 1 As shown, combined Figure 2The arch measuring device includes: a center beam 1; a supporting structure 2, which is arranged on both sides of the center beam 1; a jack plate 31, which is placed on the center beam 1; a jack 3, which is placed on the jack plate 31, and is used to apply pressure to the center beam 1 to measure the arch value of the center beam 1; a laser emitting device 4, which is placed on the jack plate 31; a scale 5, which is arranged on the supporting structure 2; wherein, when the jack 3 applies pressure to the center beam 1, the laser emitting device 4 moves along with the jack 3 toward the jack plate 31, and the laser emitting device 4 emits laser and moves along the scale 5. By setting a supporting structure 2 on both sides of the center beam 1, the arch value of the center beam 1 can be measured. When the jack 3 applies pressure to the center beam 1 and moves downward, the laser of the laser emitting device 4 set on the jack pressure plate 31 moves along with the movement of the jack 3 toward the center beam 1, and the laser also moves on the scale ruler 5. The scale value of the laser moving on the scale ruler 5 is the arch value of the center beam 1. The arch measuring device has a simple process and can ensure the consistency of the arch value. The measured arch value has high accuracy, which can ensure the quality and safety of the steel pipe, thereby improving the production efficiency and accuracy of the steel pipe hard beam.
[0028] In one embodiment, the supporting structure 2 includes: a first supporting steel plate 21; a second supporting steel plate 22, the first supporting steel plate 21 and the second supporting steel plate 22 are respectively arranged on both sides of the middle beam 1, and the scale ruler 5 is installed on the first supporting steel plate 21 or the second supporting steel plate 22. Specifically, the first supporting steel plate 21 and the second supporting steel plate 22 are arranged on both sides of the middle part of the middle beam 1, and the first supporting steel plate 21 and the second supporting steel plate 22 are both perpendicular to the ground.
[0029] It should be understood that the scale ruler 5 can be installed on the first supporting steel plate 21 or on the second supporting steel plate 22, as long as the scale ruler 5 corresponds to the position of the laser emitting device 4, that is, the laser emitted by the laser emitting device 4 can be irradiated onto the scale ruler 5.
[0030] In one embodiment, the support structure 2 also includes: a top plate 24, one end of the top plate 24 is fixedly connected to the top of the first support steel plate 21, and the other end of the top plate 24 is fixedly connected to the top of the second support steel plate 22, and the first support steel plate 21, the second support steel plate 22 and the top plate 24 form a door-like structure.
[0031] It should be understood that the top plate 24 is arranged on the top of the first supporting steel plate 21 and the second supporting steel plate 22, and the jack 3 is placed under the top plate 24. When the jack 3 is in working state, one end of the jack 3 contacts with the top plate 24. Since the position of the top plate 24 is fixed, it is ensured that the jack 3 can apply pressure in the direction of the center beam 1.
[0032] In one embodiment, the jack 3 is arranged at the center of the jack plate 31. Specifically, the jack 3 is arranged at the center of the jack plate 31, so that the pressure applied by the jack 3 to the center beam 1 can be more uniform, and the measured camber value can be more accurate.
[0033] In one embodiment, the jack plate 31 is arranged parallel to the top plate 24. Specifically, a laser emitting device and a jack are placed on the jack plate 31, and the jack plate is placed on the middle beam 1. In order to facilitate the operation of the jack 3, a top plate is arranged above the jack 3 so that the jack plate 31 is parallel to the top plate 24. When the jack 3 is in the working state, one end of the jack contacts the top plate 2, and the other end of the jack contacts the jack plate 31, which can ensure that the jack 3 can apply pressure to the middle beam 1.
[0034] In one embodiment, the laser emitting device 4 is a laser emitter 41, and the laser emitter 41 is fixedly connected to the jack platen 31. Specifically, the laser emitter 41 can be a laser emitter 41 that emits a horizontal line laser, and in this application, a mini infrared laser level from ZhonNa is selected.
[0035] It should also be understood that the laser emitter 41 can be fixed to the jack platen 31 by magnetic attraction, or the laser emitter 41 can be fixed to the jack platen 31 by bolt and nut connection. As long as the laser emitter 41 can be fixed to the jack platen 31, the present application adopts magnetic attraction to fix the laser emitter 41 to the jack platen 31, which is not only convenient for taking, but also can adjust the relative position of the laser emitter 41 with respect to the scale 5.
[0036] In one embodiment, the supporting structure 2 also includes steel plate feet 23, which fix one end of the first supporting steel plate 21 and the second supporting steel plate 22 on the ground. The steel plate feet 23 can place the first supporting steel plate 21 and the second supporting steel plate 22 firmly on both sides of the central beam 1.
[0037] The working process of the camber measuring device is as follows:
[0038] The center beam 1 should have a certain arch value during production. The theoretical arch values of center beams of different lengths can be obtained by calculation according to the formula. In actual production, a certain force is applied to the middle of the center beam 1 to achieve the arch value of the center beam 1. Support plates are set at both ends of the center beam 1 to suspend the center beam 1 so that the center beam 1 maintains a certain distance from the ground. The arch measuring device is then fixed on both sides of the middle of the center beam. A jack plate 31 is placed horizontally in the middle of the center beam 1. The laser transmitter 41 is placed on the jack plate 31. A first support steel plate 21 and a second support steel plate 22 perpendicular to the ground are respectively provided on both sides of the middle of the center beam 1. A scale ruler 5 is installed on the inner side of the first support steel plate 21 or the second support steel plate 22. When the jack 3 is in a non-working state, such as Figure 1 As shown, the laser emitter 41 on the jack plate 31 emits the laser to the zero position of the scale 5. When the jack 3 is in working state, as shown in FIG. Figure 2 As shown, the laser emitted by the laser emitter 41 on the jack 3 moves on the scale ruler 5 accordingly as the jack 3 moves downward. The laser moves with the change of the middle part of the middle beam 1, and the scale value of the laser moving on the scale ruler 5 is the arch value of the middle beam. The arch measuring device not only measures the arch value simply and quickly, but also ensures the consistency of the arch value, thereby improving the manufacturing efficiency and accuracy of the steel tube hard beam.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
