Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment installation technology, and more specifically, to a track elevation adjustment device. Background Technology

[0002] The crash test center is used for conducting crash tests on relevant vehicles. Along its central axis is a double-track traction track, approximately 230 meters long, with the two parallel tracks spaced 1.88 meters apart. To ensure the vehicle maintains smooth and uniform acceleration during the test, the track elevation must strictly comply with the drawings and relevant specifications. Typical specifications require: 1. The height difference between the highest and lowest points of the track within its normal range should not exceed 10mm; 2. The maximum straight section of the track within its normal range should not exceed 15mm; 3. The lateral misalignment and height difference between the two tracks at the joint should be less than or equal to 1mm.

[0003] The traditional method for adjusting the elevation of a single rail is as follows: 1. Based on the measured data and the data on the drawings, use manual tools such as crowbars to manually pry up the rail at each rail clamp, adding or removing shims until the elevation meets the requirements; 2. Use jacks and rail clamps to lift the rail, adding or removing shims until the elevation meets the requirements.

[0004] Using the two traditional methods mentioned above not only increases the number of repeated adjustments, but also requires two jacks to work together, which is also relatively expensive. Summary of the Invention

[0005] In view of this, the present invention proposes a track elevation adjustment device, which aims to solve the problem that the existing single track elevation adjustment method increases the number of repeated adjustments and requires two jacks to cooperate, resulting in high costs.

[0006] This utility model proposes a track elevation adjustment device, which includes: an adjustment bracket for mounting on the outer periphery of the track to be adjusted; a track clamp disposed inside the adjustment bracket in a vertically adjustable manner for clamping the track to be adjusted within the adjustment bracket and driving the track to be adjusted to be vertically lifted, thereby adjusting the adjustment shims at the bottom of the track; and a drive unit whose power output end is connected to the track clamp for driving the track clamp to perform vertical position adjustment.

[0007] Furthermore, in the above-mentioned track elevation adjustment device, the driving component includes: a driving support block, which is rotatably mounted on the adjustment bracket; and a transmission component, which is connected to the driving support block and the track clamp respectively, for converting the rotation of the driving support block into reciprocating linear motion of the track clamp in the vertical direction.

[0008] Furthermore, in the aforementioned track elevation adjustment device, the transmission component is a threaded rod, which passes through the adjustment bracket and the drive support block, and the threaded rod is threadedly connected to the drive support block to form a ball screw pair.

[0009] Furthermore, in the aforementioned track elevation adjustment device, the drive support block is a nut adapted to the threaded rod, and the nut is in rotatable contact with the top wall of the adjustment bracket.

[0010] Furthermore, in the aforementioned track elevation adjustment device, a support pad is also provided between the drive support block and the top wall of the adjustment bracket.

[0011] Furthermore, in the aforementioned track elevation adjustment device, the track clamp is provided with a fixing nut, which is threadedly connected to the bottom end of the threaded rod, for the purpose of assembling and disassembling the track clamp and the threaded rod.

[0012] Furthermore, in the aforementioned track elevation adjustment device, the fixing nut and the track clamp are connected by welding.

[0013] Furthermore, in the above-mentioned track elevation adjustment device, the track clamp includes: two intersecting and oppositely arranged clamping parts; wherein the two clamping parts are rotatably connected to each other for adjusting the position between the two clamping ends of the two clamping parts to clamp onto the track to be adjusted.

[0014] Furthermore, in the aforementioned track elevation adjustment device, there are two driving components, with the power output ends respectively connected to the two clamping parts.

[0015] Furthermore, in the aforementioned track elevation adjustment device, the adjustment bracket is a gate-shaped bracket.

[0016] The track elevation adjustment device provided by this utility model supports the track clamp and the driving component through the adjustment bracket. The track clamp holds the track to be adjusted, and the driving component drives the track clamp to adjust its vertical position, thereby driving the track to be adjusted to be vertically lifted to a preset elevation. Then, the adjustment shim at the bottom of the track to be adjusted is adjusted. After the adjustment is completed, the driving component drives the track clamp to lower its vertical position, thereby driving the track to be adjusted to fall onto the adjustment shim after adjustment, completing the elevation adjustment. The elevation adjustment can be completed in one step, and the height position of the track to be adjusted can be precisely adjusted. The adjustment is convenient. Compared with the existing technology that uses jacks for adjustment, the cost is greatly reduced. It also solves the problem that the existing single track elevation adjustment method increases the number of repeated adjustments and requires two jacks, resulting in high cost.

[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] See Figure 1 This is a schematic diagram of the track elevation adjustment device provided in an embodiment of the present invention. As shown in the figure, the device includes: an adjustment bracket 1, a track clamp 2, and a driving component 3.

[0023] The adjusting bracket 1 is used to be mounted on the outer periphery of the track 4 to be adjusted. Specifically, as shown... Figure 1 and Figure 2 As shown, the adjusting bracket 1 can be a U-shaped bracket, that is, a U-shaped cross-section, supported on both sides of the track to be adjusted by vertical support rods or vertical support plates 11, and supported above the track 4 to be adjusted by horizontal connecting rods or horizontal connecting plates 12, that is, erected on the outer periphery of the track 4 to be adjusted. Of course, the adjusting bracket 1 can also be other structures, and no limitation is made in this embodiment. The track 4 to be adjusted has an H-shaped structure.

[0024] The track clamp 2 is vertically adjustable inside the adjusting bracket 1. It is used to clamp the track 4 to be adjusted, which is placed inside the adjusting bracket 1, and to drive the track 4 to be adjusted to be vertically lifted, thereby adjusting the adjusting shim (not shown in the figure) at the bottom of the track 4. Specifically, the track clamp 2 can be a clamp structure adapted to the track 4 to be adjusted. It can clamp the track 4 to be adjusted on the upper flange plate, thereby clamping the track 4 to be adjusted and driving the track 4 to be adjusted to be raised and lowered. This causes the bottom end of the track 4 to be adjusted to disengage from the bottom adjusting shim, thereby adjusting the bottom adjusting shim, such as adding or removing the adjusting shim. After the adjusting shim is adjusted to the correct position, the track 4 to be adjusted can be lowered so that it falls onto the adjusted shim.

[0025] The power output end of the drive component 3 is connected to the track clamp 2, and is used to drive the track clamp 2 to perform vertical position adjustment, thereby driving the track 4 to be adjusted to rise and fall. Specifically, the fixed end of the drive component 3 can be fixedly installed on the adjustment bracket 1, and the power output end can be connected to the track clamp 2 to drive the track clamp 2 to perform vertical position adjustment, that is, to rise and fall, thereby driving the track 4 to be adjusted to rise and fall. In this embodiment, the power output end of the drive component 3 is detachably connected to the track clamp 2 to facilitate the assembly of the device, especially to facilitate the track clamp 2 to clamp onto the upper flange plate 41 of the track 4 to be adjusted.

[0026] See also Figure 1 and Figure 3 The track clamp 2 includes two intersecting and oppositely arranged clamping portions 21; wherein the two clamping portions 21 are rotatably connected to each other for adjusting the two clamping ends 211 of the two clamping portions 21 (e.g., ...). Figure 3 The clamping part 21 is positioned at the end between the two vertical connecting plates shown on the left and right sides, to clamp onto the track 4 to be adjusted. Specifically, the clamping part 21 can be L-shaped, that is, it includes a long arm section and a short arm section connected together. The long arm sections of the two clamping parts 21 are rotatably connected by a rotating shaft 23. When in the clamping state, the long arm sections of the two clamping parts 21 can be in a horizontal state, and the short arm section is in a vertical state. The clamping end 211 of the short wall section is provided with a clamping hook, which is hooked at the connection angle between the upper flange plate 41 and the web plate of the track 4 to be adjusted. The two clamping hooks arranged opposite to each other of the two clamping parts 21 hook onto the left and right sections of the upper flange plate 41 respectively, thereby clamping the track 4 to be adjusted. The rotating shaft 23 can be a bolt assembly.

[0027] In this embodiment, there are two drive members 3, and the power output ends of the two drive members 3 are respectively connected to the two clamping parts 21. Specifically, the power output ends of the two drive members 3 are detachably connected to the top wall ends of the long arm sections of the two clamping parts 21, so as to facilitate the synchronous lifting and lowering drive of the two clamping parts 21 and avoid the clamping parts 21 from tilting.

[0028] See also Figure 1 The driving component 3 includes a driving support block 31 and a transmission component 32; wherein the driving support block 31 is rotatably mounted on the adjusting bracket 1; the transmission component 32 is connected to the driving support block 31 and the track clamp 2 respectively, and is used to convert the rotation of the driving support block 31 into reciprocating linear motion in the vertical direction of the track clamp 2.

[0029] Specifically, the drive support block 31 can press against the top wall of the transverse connecting rod or transverse connecting plate 12 of the adjusting bracket 1, the transmission component 32 passes through the transverse connecting rod or transverse connecting plate 12 of the adjusting bracket 1, the power input end is connected to the drive support block 31, and the power output end (such as...) Figure 1 The bottom end of the transmission component 32 is detachably connected to the track clamp 2. Due to the gravity of the track clamp 2 and the track 4 to be adjusted held by the transmission component 32, the drive support block 31 presses against and is fixed to the top wall of the transverse connecting rod or transverse connecting plate 12 of the adjusting bracket 1. By manually rotating the drive support block 31, the transmission component 32 converts the rotation of the drive support block 31 into reciprocating linear motion in the vertical direction of the track clamp 2, thereby realizing the vertical lifting or lowering of the track clamp 2 and the track 4 to be adjusted held by it.

[0030] In this embodiment, the transmission component 32 is a threaded rod that passes through the adjusting bracket 1 and the driving support block 31, and the threaded rod is threadedly connected to the driving support block 31 to form a ball screw pair. Specifically, by rotating the driving support block 31, the transmission component 32 reciprocates linearly in the vertical direction, thereby driving the track clamp 2 connected to the bottom end of the transmission component 32 and the clamped track 4 to be adjusted to be vertically lifted or lowered. Of course, in other embodiments, the transmission component 32 and the driving support block 31 can also be other structures, such as a gear and rack structure, and this embodiment does not limit them in any way. The driving support block 31 can be a nut adapted to the screw structure, and the nut is rotatably pressed against the top wall of the adjusting bracket 1. By rotating the driving support block 31 clockwise, the transmission component 32 reciprocates linearly in the vertical direction. Preferably, a support pad 33 is further provided between the drive support block 31 and the top wall of the adjusting bracket 1 to reduce friction between the drive support block 31 and the top wall of the adjusting bracket 1. The support pad 33 can be a flat pad. In this embodiment, the transverse connecting rod or transverse connecting plate 12 of the adjusting bracket 1 is provided with two vertically arranged light holes, and two transmission components 32 pass through the two light holes and can move along the axial direction of the light holes (e.g., along the axial direction of the light holes). Figure 1 (It moves in a reciprocating linear motion in the vertical direction shown).

[0031] In this embodiment, the track clamp 2 is provided with a fixing nut 22, which is threadedly connected to the bottom end of the threaded rod. This allows for the assembly and disassembly of the track clamp 2 and the threaded rod, facilitating the connection between the track clamp 2 and the threaded rod after the track clamp 2 is clamped onto the track 4 to be adjusted. The fixing nut 22 and the track clamp 2 can be connected by welding or other methods; this embodiment does not impose any limitations on these methods.

[0032] The assembly and use method of this device is as follows: First, assemble the two clamping parts 21 into a track clamp 2 by means of the rotating shaft 23, and tighten the transmission part 32, i.e., the threaded rod, to the fixing nut 22 welded on the two clamping parts 21 respectively. Clamp the track clamp 2 on the track 4 to be adjusted, i.e., the track whose elevation needs to be adjusted. Then, put the adjusting bracket 1 on top of the track clamp 2, align the two threaded rods with the two holes on the adjusting bracket 1, and screw the two sets of matching drive support blocks 31 on the two threaded rods so that they are screwed onto the top wall of the adjusting bracket 1 to press against the top wall of the adjusting bracket 1, thereby fixing the threaded rods to the adjusting bracket 1. Then, turn the adjustable wrench or open-end wrench clockwise. Tighten the two drive support blocks 31 evenly. During the tightening process, the two threaded rods move upward, driving the track clamp 2 upward to gradually clamp the track 4 to be adjusted. Using the adjusting bracket 1 as a support, the track 4 to be adjusted is gradually lifted until it reaches the preset elevation. After the elevation of the upper surface of the track 4 to be adjusted meets the requirements of the drawing, adjust the shims at the lower end of the track 4 to be adjusted. Finally, tighten the two drive support blocks 31 counterclockwise. During the tightening process, the two threaded rods move downward, driving the track clamp 2 and the track 4 to be adjusted upward until the track 4 to be adjusted rests on the adjusting shims. Check whether the elevation meets the requirements. If it does not meet the requirements, repeat the above steps until the requirements are met. The preset elevation can be determined according to the actual situation. In this embodiment, it is not limited in any way.

[0033] In summary, the track elevation adjustment device provided in this embodiment supports the track clamp 2 and the driving component 3 through the adjustment bracket 1. The track clamp 2 holds the track 4 to be adjusted, and the driving component 3 drives the track clamp 2 to adjust its vertical position, thereby lifting the track 4 to the preset elevation. Then, the adjustment shim at the bottom of the track 4 is adjusted. After the adjustment is completed, the driving component 3 drives the track clamp 2 to lower its vertical position, thereby lowering the track 4 to the adjustment shim so that the track 4 falls onto the adjusted shim, completing the elevation adjustment. The elevation adjustment can be completed in one step, and the height position of the track 4 can be precisely adjusted and is convenient to adjust. Compared with the existing technology that uses jacks for adjustment, the cost is greatly reduced, and the problem of the existing single track elevation adjustment method increasing the number of repeated adjustments and requiring two jacks to cooperate, resulting in high cost, is solved.
