[0051] like Figure 1 As shown, this embodiment provides a non-stop automatic track scale with a track-grip beam structure to solve the problem that due to the busy operation of the railway line, it is impossible to provide a long time for the line to be closed to build the foundation of the track scale, overcome the difficulties in the construction of the track scale, greatly shorten the construction time, and speed up the construction speed.

[0052] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4The non-stop track automatic track scale with a track-grip beam structure includes a track scale bearing base 1 and a beamless non-stop track automatic track scale 2. The track scale bearing base 1 includes a frame-type track-grip steel beam 11 and a bearing pier 12. The frame-type track-grip steel beam 11 extends along a preset direction. Bearing piers 12 are provided at both ends of the frame-type track-grip steel beam 11 in the width direction, and both ends of the frame-type track-grip steel beam 11 are connected to the corresponding bearing piers 12; the beamless non-stop track automatic track scale 2 includes a rail 21 and a weighing unit. The weighing unit includes a combined rail pad type weighing sensor 22 and a pin type weighing sensor 23. The rail 21 is provided on the combined rail pad type weighing sensor 22. The combined rail pad type weighing sensor 22 is provided on the frame-type track-grip steel beam 11. The pin type weighing sensor 23 is provided on the waist of the rail 21. The weighing unit is used to weigh vehicles passing through the rail.

[0053] The track scale support foundation 1 is used to support a beamless, non-stop, automatic track scale 2. By configuring the track scale support foundation 1 as a combination of a frame-type rail-gripping steel beam 11 and supporting piers 12, it replaces the traditional reinforced concrete structure of the track scale support foundation 1. During construction, the supporting piers 12 on both sides are first constructed, and then the prepared frame-type rail-gripping steel beam 11 is erected and connected to the supporting piers 12. The supporting piers 12 can be constructed when the line is idle, eliminating the need to close the line. Erecting the frame-type rail-gripping steel beam 11 and installing the beamless, non-stop, automatic track scale 2 only requires one to two days of track closure. This effectively solves the problem of long track closures for track scale construction due to busy railway lines, overcomes the difficulties of track scale construction, significantly shortens construction time, and increases construction speed. Furthermore, the beamless, non-stop, automatic track scale 2 avoids the deep foundation trench excavation required for beam-type track scales, which can damage the line's roadbed structure. The non-stop rail structure ensures smooth operation of freight trains, improving line safety and weighing accuracy.

[0054] If a track scale with a beam structure is used, the excavation of the foundation trench is too deep, which will affect the stability of the bearing foundation and cause damage to the line subgrade structure. The technical solution adopted in this embodiment is to use a beamless, uninterrupted track automatic track scale 2 with a rail 21 as the track scale carrier. The foundation trench only needs to be excavated to the ballast layer, which will not damage the subgrade structure of the line, and has smooth drainage, a simple structure, and is easy and quick to install.

[0055] In this embodiment, see Figure 3 and Figure 4The load-bearing pier 12 includes a reinforced concrete casting pier 121 and a pre-embedded adjustment structure 122 embedded in the reinforced concrete casting pier 121. The frame type rail-gripping steel beam 11 is welded to the pre-embedded adjustment structure 122. The pre-embedded adjustment structure 122 is used to adjust the corresponding position of the frame type rail-gripping steel beam 11 relative to the reinforced concrete casting pier 121. The corresponding position includes the elevation of the frame type rail-gripping steel beam 11 relative to the reinforced concrete casting pier 121. The reinforced concrete casting pier 121 is set on the outside of the track sleeper, and its reinforced concrete structure can be formed through on-site casting construction. The pre-embedded adjustment structure 122 facilitates welding with the frame type rail-gripping steel beam 11, so that the load-bearing pier 12 and the frame type rail-gripping steel beam 11 are firmly installed together. Moreover, the pre-embedded adjustment structure 122 can adjust the height and / or angle of the frame type rail-gripping steel beam 11 to achieve the best installation state.

[0056] Exemplarily, the embedded adjustment structure 122 includes an embedded steel plate and an adjustment device connected to the embedded steel plate. Its specific structure is an inclined iron pad.

[0057] Specifically, after the frame type rail buckle steel beam 11 and the bearing pier 12 are adjusted, they are welded and fixed, and then the frame type rail buckle steel beam 11 is backfilled with ballast and tamped.

[0058] For example, the frame-type rail-clamping steel beam 11 is made of H-shaped steel. Its rigidity exceeds the requirement of GB / T11885-2015 "Automatic Rail Scales," which stipulates that the deflection of the load carrier under maximum load should not exceed 0.3‰. The frame-type rail-clamping steel beam 11 is manufactured in a modularized manner in the factory, assembled on-site, and welded into a single structure.

[0059] In this embodiment, the design bearing capacity of the bearing buttress 123 is 25t, the foundation trench of the bearing buttress 12 is excavated to the frozen soil layer, and the foundation bearing capacity of the foundation trench is ≥150KPa.

[0060] See also Figure 3 and Figure 4 The frame-type rail-clamping steel beam 11 includes a first rail steel beam 111 and a second rail steel beam 112. The first rail steel beam 111 is arranged in two sections side by side, and both extend along a preset direction for supporting the rail 21. The second rail steel beam 112 is arranged in multiple sections at intervals along the preset direction and extends along the width direction of the first rail steel beam 111. The second rail steel beam 112 is cross-connected to the first rail steel beam 111, and both ends of the second rail steel beam 112 are respectively connected to the bearing pier 12.

[0061] The above-mentioned preset direction is the extension direction of the rail 21. By providing a plurality of second rail steel beams 112, while connecting the two first rail steel beams 111, the second rail steel beams 112 can also be connected to the supporting pier 12.

[0062] like Figure 4 and Figure 5 As shown, the weighing unit includes a combined rail pad type weighing sensor 22, which includes a pressure sensor 221 and a spring bar baffle seat 222. An installation space for accommodating the pressure sensor 221 is defined between the rail 21 and the frame type rail clip steel beam 11. The upper surface of the pressure sensor 221 contacts the rail bottom of the rail 21, and the lower surface of the pressure sensor 221 contacts the frame type rail clip steel beam 11, so that the pressure sensor 221 can move horizontally in and out of the installation space along the width direction of the rail 21. Two spring bar baffle seats 222 are provided, one on each side of the rail bottom of the rail 21, and both are detachably connected to the pressure sensor 221 via fasteners 223. The spring bar baffle seats 222 are used to limit the movement of the pressure sensor 221 along the width direction of the rail 21.

[0063] The pressure sensor 221 can be along Figure 5 The middle rail 21 moves horizontally in and out between the rail 21 and the frame-type rail-grip steel beam 11 in the width direction. This allows for quick installation and removal of the pressure sensor 221 without having to lift the rail 21. The two spring bar baffles 222 act as a stop, preventing the combined rail pad-type load cell 22 from moving along the width direction of the rail 21 after installation.

[0064] Furthermore, the spring bar baffle seat 222 includes a baffle seat 2221 and a spring bar 2222. The baffle seat 2221 is stopped on one side of the rail 21. The fastener 223 passes through the spring bar 2222 and the baffle seat 2221 and is connected to the pressure sensor 221. The pressure sensor 221 is provided with a first guide structure, and the baffle seat 2221 is provided with a second guide structure. The first guide structure and the second guide structure slide together to allow the two baffle seats 2221 to move closer to or away from each other. When installing the baffle seat 2221, the baffle seat 2221 is slid onto the pressure sensor 221 along the width of the rail 21. Once it is in place, the fastener 223 is passed through the spring bar 2222 and the baffle seat 2221 and connected to the pressure sensor 221.

[0065] Exemplarily, the fastener 223 is a bolt.

[0066] Specifically, if Figure 5 、 Figure 6 as well as Figure 7As shown, the first guide structure includes a first slot 2211 recessed on opposite side surfaces of the pressure sensor 221, and the pressure sensor 221 forms a guide rail 2212 above the first slot 2211. The second guide structure includes a T-shaped slot 2221a provided on the baffle seat 2221. The baffle seat 2221 forms two spaced guide blocks 2221b and two spaced second slots 2221c by providing the T-shaped slot 2221a. The guide blocks 2221b are slidably engaged with the first slot 2211, and the second slots 2221c are slidably engaged with the guide rail 2212. When installing or removing the baffle seat 2221, the guide blocks 2221b of the baffle seat 2221 slide within the first slot 2211, and the second slots 2221c slidably engage with the guide rail 2212, thereby sliding the baffle seat 2221 into place.

[0067] Specifically, when installing the combined rail pad type weighing sensor 22, first slide the pressure sensor 221 horizontally under the rail 21, then slide the two baffle seats 2221 along the pressure sensor 221 into place, and finally use the fasteners 223 to pass through the spring bars 2222 and the baffle seats 2221 and connect them to the pressure sensor 221. When disassembling, loosen the fasteners 223, slide the baffle seats 2221 in the opposite direction to remove them, and finally pull the pressure sensor 221 horizontally out from under the rail 21. There is no need to lift the rail 21 during the entire process, making the installation and replacement of the combined rail pad type weighing sensor 22 faster and more convenient, and reducing the difficulty of installation and replacement.

[0068] See also Figure 5 The beamless, non-stop track automatic track scale 2 further includes an insulating component 24, which includes an insulating pad 241 and an insulating pressure strip 242. Both sides of the rail bottom of the rail 21 are covered with insulating pressure strips 242. The insulating pad 241 is located on the bottom surface of the rail bottom of the rail 21, and a first sink 2213 for clamping the insulating pad 241 is provided on the pressure sensor 221. For further information, see Figure 4 The frame-type rail-fastening steel beam 11 includes an effective weighing section and guide rail sections at both ends of the effective weighing section. The effective weighing section is provided with a plurality of combined rail pad type weighing sensors 22. The guide rail area is provided with a sleeper trough plate 3 for supporting the rail 21. The sleeper trough plate 3 is provided with a second trough 31 for clamping the insulating pad 241. Figure 3 shown.

[0069] The shape of the insulating strip 242 is adaptively matched with the shape of the rail bottom on one side of the rail 21. The insulating pad 241 and the insulating strip 242 are used to wrap the rail 21 and then install it in the first groove 2213 of the combined rail pad type weighing sensor 22 in the effective weighing section and in the second groove 31 of the sleeper groove plate 3 in the guide rail section. The insulating pad 241 and the insulating strip 242 insulate the rail 21, so that the line forms a track circuit structure.

[0070] See also Figure 4 The weighing unit includes two sets of spaced-apart pin-type load cells 23, which are installed on the waist of the rail 21. The two sets of pin-type load cells 23 separate the rail 21 into a weighing rail and guide rails installed at both ends of the weighing rail. The weighing rail is located in the effective weighing section, and the guide rail is located in the guide rail section. The above-mentioned rail 21 is a rail 21 of the same specifications as the existing line, and a 25m standard new rail is required. The center point of the rail 21 is located at the center point of the effective weighing section. The rail 21 in the effective weighing section serves as the load carrier of the track scale, and the rail 21 outside the effective weighing section serves as the guide rail.

[0071] See also Figure 4 The track scale also includes a vehicle number recognition system 4, which is a device that automatically reads the model and vehicle number information of railway freight cars passing through the effective weighing section. It includes an antenna, a radio frequency cable, and a vehicle number host. The antenna is installed at the center of the effective weighing section, and the vehicle number host is placed in the control room and connected to the antenna through a radio frequency cable.

[0072] Furthermore, the beamless non-stop automatic track scale 2 also includes a dynamic weighing instrument, which is configured to be placed in the control room and is communicatively connected to the weighing unit. Specifically, the pin-type weighing sensor 23, the combined rail pad-type weighing sensor 22, and the signal output lines of the vehicle number recognition system 4 are introduced into the control room through the threading tube and connected to the dynamic weighing instrument. The dynamic weighing instrument is used to convert the carrying signal and vehicle information output by the combined rail pad-type weighing sensor 22, the pin-type weighing sensor 23, and the vehicle number recognition system 4 through its own AD conversion module, calculation module, and display module, and finally display the relevant information and data of the weighing measurement and vehicle number recognition of each truck. The dynamic weighing instrument is an existing mature technology and will not be described in detail here.

[0073] The working process of the track scale is roughly as follows:

[0074] When the truck train enters the effective weighing section at a constant speed, the pin-type weighing sensor 23 at the entrance end outputs a shear force electrical signal, instructing the dynamic weighing instrument to turn on. After the truck train has passed, the pin-type weighing sensor 23 at the exit end outputs a shear force electrical signal, instructing the dynamic weighing instrument to turn off. During the operation, the dynamic weighing instrument collects the electrical signals output by the pin-type weighing sensor 23 and the combined rail pad-type weighing sensor 22 at high speed, automatically converts the collected electrical signals into digital signals and transmits them to the calculation module. The calculation module automatically corrects and compensates the converted data and the vehicle-related information collected and transmitted by the vehicle number recognition system 4 according to the compiled legal metrology weighing software program settings, and displays the weighing time, vehicle model, vehicle number, speed, gross weight, tare weight, net weight, vehicle weight difference, vehicle load imbalance rate and other related data of each truck, and can transmit this data to the industrial computer. Combined with the weighing management software, it can meet customer needs and display complete weighing and measurement related information, and finally store the weighing and measurement related information of each train in a relational database (or remote network server) for future query and further data processing.

[0075] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
