Description

Technical Field

[0001] The utility model relates to the field of track devices, in particular to a heavy-load trolley track device. Background Art

[0002] Track systems are devices that allow objects to move along a specific trajectory. They can significantly improve production efficiency and offer advantages such as high stability, large load-bearing capacity, and easy maintenance. Therefore, they are widely used in industrial automation equipment, high-bay warehouses, and production lines. Track systems used with functional equipment typically require leveling and maintaining the track within a high precision range to ensure smooth movement and operation. However, during track installation, the ground is often not perfectly level. Installing the track directly on the ground would not easily meet the operational and precision requirements of the equipment. Most existing track systems only feature a leveling mechanism, while left-right alignment is simply achieved by tapping left and right during installation. This results in crude and time-consuming adjustments, low installation efficiency, and poor accuracy. Track leveling is often achieved using a base plate and thin shims, which often results in large height differences between different adjustment sections and relatively poor track stability after installation. Overall, traditional equipment track leveling is difficult, installation and commissioning are complex, and maintenance efficiency is low. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a heavy-load trolley track device, which includes one or more track mechanisms, wherein the track mechanism includes: a base plate, a steel rail, and a leveling component for adjusting the upper and lower positions of the steel rail and a straightening component for adjusting the left and right positions; the leveling component includes a thick pad, a thin pad and an adjusting top screw; the upper and lower surfaces of the base plate are both horizontal surfaces, and are fixed on a workbench or the ground; the thick pad is fixed to the base plate, and the steel rail is fixed to the thick pad, and a thin pad is provided between the thick pad and the base plate, and a plurality of through threaded holes matched with the adjusting top screw are provided on the thick pad, and the adjusting top screw is screwed to the threaded hole to determine the thickness of the thin pad compensation; the straightening components are respectively arranged on both sides of the steel rail; each steel rail is provided with at least two groups of leveling components and two groups of straightening components.

[0006] Furthermore, the thicknesses of the plurality of thick pads are all consistent, and the thickness of the thin pad is equal to the thickness compensated after the top screw is adjusted to be leveled.

[0007] Furthermore, the base plate is composed of several sub-base plates spliced ​​in parallel, and each sub-base plate is fixed to the workbench or the ground by chemical bolts or expansion bolts; thick pads and thin pads are provided between each sub-base plate and the rails.

[0008] Furthermore, the thick pad is fixed to the base plate by bolts.

[0009] Furthermore, the rail is pressed against the thick pad by fixed pressure blocks arranged on both sides of the rail. The fixed pressure blocks include pressure blocks, fixing bolts and fastening bolts. One end of the pressure block is fixed to the thick pad by the fixing bolts, and the other end is pressed down on the edge of the rail. A fastening bolt is arranged in the middle of the pressure block to press the pressure block against the edge of the rail.

[0010] Furthermore, the straightening assembly includes an adjusting fixed block and an adjusting bolt. The adjusting fixed block is fixed on the base plate. A horizontal threaded hole is provided on the fixed block to be screwed to the adjusting bolt. The adjusting bolt passes through the horizontal threaded hole and abuts against one side of the rail for adjusting the left and right position of the rail.

[0011] Furthermore, the track mechanism also includes an anti-tilt guide rail and a mechanical limit block fixed on the thick pad. The anti-tilt guide rail is arranged on the inner side of the steel rail and parallel to the steel rail. The anti-tilt guide rail is an I-beam, one side of which is a sliding groove that is engaged with the trolley running wheel box, and the other side is provided with a number of ribs for reinforcement; the mechanical limit block is arranged on the bottom plate, located at one end of the steel rail, and is used to prevent the heavy-loaded trolley from derailing at the end during operation.

[0012] Furthermore, there are two track mechanisms, which are arranged parallel to each other.

[0013] The above-mentioned debugging method of the heavy-duty trolley track device includes the following steps:

[0014] S1. Roughly level all sub-bases and fix them on the workbench or floor;

[0015] S2. Place the rails and leveling components, and fine-level the entire structure: lay the thick pads on the base plate, fix the rails on the thick pads, screw in the adjustment screws to fine-level the rails, and secure the thick pads to the base plate.

[0022] The benefits of this utility model are:

[0023] 1.

[0051] like Figure 1 As shown, the present invention discloses a heavy-duty trolley track device, which includes one or more track mechanisms 100. In this embodiment, two track mechanisms 100 are provided and are arranged parallel to each other.

[0052] Among them, such as Figure 1 、 Figure 2 As shown, the track mechanism 100 includes: a base plate 1, a steel rail 5, an anti-tilt guide rail 8 and a mechanical limit block 13, as well as a leveling component for adjusting the upper and lower positions of the steel rail 5 and a straightening component for adjusting the left and right positions.

[0053] Specifically, the base plate 1 is composed of several sub-base plates 101 joined together in parallel, each of which is secured to a workbench or the ground using chemical bolts 9 or expansion bolts. Multiple sub-base plates 101 secured in parallel to the floor significantly increase the contact area with the ground, effectively distributing the load and reducing ground pressure. Furthermore, they can better adapt to uneven ground surfaces and facilitate the installation and leveling of the rails 5.

[0054] Specifically, if Figure 3As shown, the leveling assembly includes a thick pad 4, a thin pad 3 and an adjustment screw 2. The upper and lower surfaces of the base plate 1 are both horizontal and fixed to a workbench or the ground. The thick pad 4 is fixed to the base plate 1 by bolts, and the rail 5 is pressed against the thick pad 4 by fixed pressure blocks 6 arranged on both sides of the rail 5. A thin pad 3 is arranged between the thick pad 4 and the base plate 1. The thick pad 4 is provided with a number of through-threaded holes that match the adjustment screw 2. The adjustment screw 2 is screwed to the threaded holes to determine the thickness compensated by the thin pad 3. Among them, the thickness of the thick pad 4 is uniform, and the thickness of the thin pad 3 is equal to the thickness compensated after the adjustment screw 2 is adjusted and leveled. Each rail 5 is provided with at least two sets of leveling assemblies. In this embodiment, for greater stability, a leveling assembly is provided on each sub-base plate 101, that is, a thick pad 4 and a thin pad 3 are provided between each sub-base plate 101 and the rail 5.

[0055] During leveling, the thick pad 4 is laid on the base plate 1, and the rail 5 is fixed on the thick pad 4. The rail 5 is finely leveled as a whole by screwing in the adjusting screw 2, and the thick pad 4 is fixed to the base plate 1. Then, the gap between the bottom surface of each thick pad 4 and the corresponding base plate 1 at the four corners is measured in turn, and finally an actual required height value is determined, and thin pads 3 of corresponding thickness are processed in turn for matching height and leveling; during installation, the adjusting screw 2 is removed from the thick pad 4, and then the thin pad 3 is inserted into the gap and fixed to the base plate 1; the adjusting screws 2 are replaced one by one and fixed to ensure that the original leveling is not damaged. The combined installation of the thick pad 4 and the finely processed thin pad 3 can effectively ensure the accuracy of the track device and withstand heavy-load rails 5 for a long time. Leveling is achieved by first adjusting the screw 2 for overall leveling, and then replacing the adjusting screw 2 with an appropriate thin pad for load bearing, making the leveling of the rail 5 simpler and more efficient, and can effectively ensure the stability of the rail 5 when bearing heavy loads.

[0056] The fixed pressure block 6 includes a pressure block 61, a fixing bolt 62, and a fastening bolt 7. One end of the pressure block is fixed to the thick base plate 4 by the fixing bolt 62, and the other end is pressed down on the edge of the rail 5. The fastening bolt 7 is set in the middle of the pressure block to press the pressure block against the edge of the rail 5.

[0057] Specifically, if Figure 4 As shown, the straightening assembly includes an adjustment block 11 and an adjustment bolt 12. The adjustment block 11 is fixed to the base plate 1. The block is provided with a horizontal threaded hole that is threaded with the adjustment bolt 12. The adjustment bolt 12 passes through the horizontal threaded hole and abuts against one side of the rail 5 to adjust the left and right position of the rail 5. The straightening assemblies are installed on both sides of the rail 5; each rail 5 is equipped with at least two sets of leveling assemblies and two sets of straightening assemblies. The bilaterally symmetrical arrangement makes adjustment more convenient and efficient.

[0058] Specifically, the anti-tilt guide rail 8 is located inside and parallel to the steel rail 5. It is an I-beam with a sliding groove on one side that engages with the trolley's wheel box 10, and a number of reinforcing ribs on the other side. The anti-tilt guide rail 8 applies the forward tilting moment of the loaded trolley to the base plate 1, limiting its forward and backward tilting while also increasing its cantilever load. This results in a more balanced overall load distribution, a more stable structure, and enhanced safety.

[0059] Specifically, the mechanical limit block 13 is provided on the base plate 1 at one end of the rail 5 and is used to perform a hard limit on the travel of the heavy-loaded trolley to prevent the heavy-loaded trolley from derailing at the end during operation.

[0060] This embodiment also discloses a method for debugging the heavy-duty trolley track device, which includes the following steps:

[0061] S1. After roughly leveling each sub-base plate 101 using a level ruler, all sub-base plates 101 are fixed side by side on a workbench or floor using chemical bolts 9 or expansion bolts.

[0062] S2. Place the rails 5 and leveling components, and fine-level them as a whole: lay the thick pads 4 on the base plate 1, fix the rails 5 on the thick pads 4, screw in the adjusting screws 2 to fine-level the rails 5 as a whole, and securely connect the thick pads 4 to the base plate 1. Then, measure the gaps between the bottom surface of each thick pad 4 and the corresponding base plate 1 at the four corners in turn, and finally determine the actual required pad height value. Then, process thin pads 3 of corresponding thickness to match and level them in turn. During installation, remove the adjusting screws 2 from the thick pads 4, then insert the thin pads 3 into the gaps and secure them to the base plate 1. Replace the adjusting screws 2 one by one and secure them to ensure that the original leveling is not damaged.

[0063] S3. Install straightening components on both sides of each rail 5, loosen the rails 5, rotate the adjusting bolts 12 to push the rails 5 to the left and right positions to adjust the joints of adjacent rails 5 to the same straight line, and fix the rails 5 on the thick base plate 4;

[0064] S4. Install the anti-tilt guide rail 8 on the thick backing plate 4. The anti-tilt guide rail 8 is located on the inner side of the rail 5, and the anti-tilt guide rail 8 is adjusted to be parallel to the rail 5.

[0065] S5. Fix a mechanical limit block 13 on the bottom plate 1 , where the mechanical limit block 13 is located at one end of the rail 5 .

[0066] In summary, the utility model can realize the rapid leveling and straightening of the track, improve the track installation accuracy, and effectively solve the problem of inconvenience in equipment installation and rotation caused by the horizontal difference of the ground.

[0067] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the various technical features in any other appropriate manner. These simple variations and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.
