Technical Field

[0001] This utility model relates to the technical field of spiral rail spikes, and in particular to a spiral rail spike pull-out force testing machine. Background Technology

[0002] With the progress of the times and the continuous development of technology, spiral rail spikes have played a significant role in the construction of railway tracks. Due to their stability, spiral rail spikes are used at the tight joints of railway tracks to improve railway safety performance. However, there are certain requirements for the pull-out force of spiral rail spikes. Therefore, it is particularly important to develop a spiral rail spike pull-out force testing machine.

[0003] Chinese utility model patent application CN205300814U discloses an electric spiral rail spike pull-out force testing machine, comprising a force equalizing plate, two tie rods, a pressure gauge, an electric jack, and a power supply. The force equalizing plate presses on the pressure gauge, and the pressure gauge presses on the top of the electric jack. The electric jack is mounted on a concrete sleeper and connected to the power supply via a power cord, which has a switch. The force equalizing plate is connected to two spiral rail spikes via the two tie rods. The lower part of the tie rod has an internal thread for connecting to the spiral rail spikes, and the upper end of the tie rod has a pressure cap that presses against the force equalizing plate. This utility model uses an electric jack as a power source to simultaneously test the pull-out force of two spiral rail spikes on one side of a concrete sleeper, improving on-site testing efficiency. The use of an integrated, threshold-adjustable buzzer-type pressure gauge reduces operational difficulty, and setting different pressure thresholds improves the instrument's versatility.

[0004] When in use, this spiral rail spike pull-out force testing machine can simultaneously test the pull-out force of two spiral rail spikes on one side of a concrete sleeper, improving the efficiency of on-site testing. However, in actual use, the following defects still exist: the size of the hole in the tension plate of the device is fixed, making it inconvenient to stably clamp spiral rail spikes of different sizes. When the spikes are lifted by the jack, the spikes and the top plate holding the spikes are prone to bounce off and injure people. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a spiral rail spike pull-out force testing machine includes a local track 1, a support frame 3 disposed at the top of the local track 1, a drive assembly 5 mounted at the top of the support frame 3, a spiral rail spike body 7 disposed at the top of the local track 1, and a side door 8 mounted on one side of the top of the support frame 3. A clamping structure 2 is also included, comprising a connecting plate 201 fixed to the bottom of the drive assembly 5, connecting bolts 202 threaded into the connecting plate 201, a base plate 203 disposed on both sides of the bottom of the connecting plate 201, and a clamping mechanism 2. The mounting groove 204 on the outer side of the top of the 203, the detection ring 205 set on the inner side of the top of the mounting groove 204, and the collar 206 threaded to the outer wall of the spiral rail spike body 7, the connecting bolts 202 are evenly arranged at the corner positions of the connecting plate 201, the bottom end of the connecting bolts 202 penetrates the connecting plate 201 and is threaded to the mounting groove 204 at the top of the bottom plate 203, the detection ring 205 is equipped with a pressure sensor, and the pull rod at the bottom of the drive assembly 5 penetrates the support frame 3 and is fixedly connected to the connecting plate 201.

[0029] It should be noted that when testing the spiral rail spike, first place the collar 206 at the appropriate position on the top of the spiral rail spike body 7, then place the base plate 203 under the bottom of the collar 206, and then place the entire device on top. Use the connecting bolt 202 to connect the connecting plate 201 and the base plate 203 together. Thus, the top of the spiral rail spike body 7 can be stably clamped by the cooperation of the connecting plate 201, connecting bolt 202, base plate 203, mounting groove 204, detection ring 205 and collar 206. When encountering spiral rail spikes of different sizes, simply replace the base plate 203, detection ring 205 and collar 206 with different hole sizes.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the buffer structure 6 is located at the bottom of the support frame 3 and is used to buffer the impact of the connecting plate 201 on the support frame 3 when the spiral spike body 7 is pulled off. The buffer structure 6 includes a limiting groove 601 opened on the inner side wall of the bottom of the support frame 3, a sliding plate 602 set above the connecting plate 201, and a buffer spring 603 set at the top of the sliding plate 602. Slider blocks are fixed on both sides of the sliding plate 602, and the limiting groove 601 and the sliding plate 602 are slidably connected.

[0031] It should be noted that the limiting groove 601 on both sides of the inner wall of the support frame 3 limits the sliding of the slide plate 602, preventing it from wobbling. The limiting groove 601, the slide plate 602, and the buffer spring 603 are located between the support frame 3 and the connecting plate 201. When the spiral road stud body 7 is pulled out, it is restricted by the collar 206 and will not pop out. The connecting plate 201 then impacts the slide plate 602 upward with the pull rod of the drive component 5. The impact force is buffered by the buffer spring 603, reducing damage to the support frame 3.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a detection structure 4 is provided on the top of the support frame 3. The detection structure 4 includes a pressure display gauge 401 installed on the outer wall of the support frame 3, a data processor 402 installed inside the support frame 3, and a built-in power supply 403. Wires are connected between the pressure display gauge 401 and the drive assembly 5, and the wires are all hidden inside the support frame 3.

[0033] It should be noted that during testing, the detection ring 205 transmits the pressure to the data processor 402. After processing by the data processor 402, the pressure is transmitted to the pressure display 401 for display. The built-in power supply 403 continuously supplies power to the pressure display 401 and the data processor 402 inside the support frame 3. The pressure display 401, the data processor 402, and the built-in power supply 403 inside the support frame 3 can display the pressure data detected by the detection ring 205 to the worker for recording.

[0034] When using this invention to test a spiral road spike, first place the collar 206 at a suitable position on the top of the spiral road spike body 7, then place the base plate 203 under the bottom of the collar 206, and then place the entire device on top. Connect the connecting plate 201 and the base plate 203 together with the connecting bolts 202. When encountering spiral road spikes of different sizes, simply replace the base plate 203, the detection ring 205, and the collar 206 with different hole sizes. The limiting groove 601 on both sides of the inner wall of the support frame 3 limits the sliding of the slide plate 602, preventing the slide plate 602 from wobbling during sliding. The limiting groove 601, the slide plate 602, and the buffer spring 603 are located between the support frame 3 and the connecting plate 201. When the spiral road spike body 7 is pulled out... When the ring 206 is confined within the connecting plate 201, it will not pop out and injure people. The connecting plate 201 impacts the slide plate 602 upward with the pull rod of the drive component 5. The impact force is buffered by the buffer spring 603, reducing damage to the support frame 3. During testing, the detection ring 205 transmits the pressure to the data processor 402. After being processed by the data processor 402, it is transmitted to the pressure display 401 for display. The built-in power supply 403 continuously supplies power to the pressure display 401 and the data processor 402 inside the support frame 3. The pressure display 401, the data processor 402, and the built-in power supply 403 inside the support frame 3 can display the pressure data detected by the detection ring 205 to the workers for recording. When the built-in power supply 403 is out of power, the side door 8 can be opened to replace it.

[0035] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
