Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, specifically to an RGV mother-daughter vehicle track structure. Background Technology

[0002] In modern industrial automated warehousing and logistics systems, RGVs (Rail Guided Vehicles) are widely used as efficient and reliable material handling equipment in smart factories, automated warehouses, and other scenarios. RGV mother-daughter vehicle systems, through the coordinated operation of the main vehicle and the daughter vehicle, can achieve material handling along complex paths, significantly improving transportation efficiency. However, existing RGV mother-daughter vehicle track structures still have many shortcomings: the installation accuracy of the tracks significantly affects the operational stability of the RGV, but the existing track support structures are difficult to adapt to uneven ground and settlement problems, lacking effective adjustment methods, which can easily lead to track tilting or deformation, causing RGV malfunctions such as jamming and derailment, affecting system operational efficiency and safety. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an RGV mother-daughter vehicle track structure with a ground mat assembly, enabling the track to be correctly installed even on uneven ground.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides an RGV mother-daughter vehicle running track structure, including:

[0005] Two parallel tracks, each track comprising multiple sub-tracks connected in a "line" configuration;

[0006] Multiple parallel cross braces, with each end of the cross brace connected to one of two tracks;

[0007] Multiple floor mat assemblies are installed below the track to support it;

[0008] The ground mat assembly includes two support units respectively located on both sides of the bottom of the track. The support unit adjusts its support height through an adjustment structure so that the bottom of the support unit touches the ground.

[0009] Preferably, the top of the sub-track is provided with a main wheel groove, the two sides of the sub-track are symmetrically provided with auxiliary wheel grooves, the bottom of the sub-track is provided with a protrusion, and the floor mat assembly is provided on both sides of the protrusion.

[0010] Preferably, the support unit includes:

[0011] A connecting plate, which is fixed below the auxiliary wheel groove by bolts;

[0012] A support plate, which is hinged to a connecting plate.

[0013] Preferably, the adjustment structure includes:

[0014] A ball joint seat, which is fixed to the side of the protrusion by bolts;

[0015] An adjusting rod, which is hinged to the protrusion via a ball joint seat;

[0016] The support plate has a through groove, the adjusting rod passes through the through groove, and the adjusting rod on the side of the support plate away from the ball joint seat is provided with a clamping mechanism.

[0017] Preferably, the clamping mechanism includes:

[0018] A spherical sleeve is fitted onto the adjusting rod on the side of the support plate away from the ball joint seat, and a spherical groove adapted to the spherical sleeve is provided on the through groove.

[0019] The locking nut is fitted onto the adjusting rod on the side of the spherical sleeve away from the support plate, and is threaded into the adjusting rod.

[0020] Preferably, the end of the support plate away from the connecting plate is provided with a pad, and the pad is provided with a positioning hole.

[0021] Preferably, the foot is fixed to the ground by an expansion bolt passing through a positioning hole.

[0022] Preferably, the protrusion has multiple through holes, and the cross brace is fixedly connected to the protrusion by bolts passing through the through holes.

[0023] Preferably, the cross-section of the through hole is waist-shaped.

[0024] Preferably, the groove walls of the main wheel groove and the auxiliary wheel groove gradually taper inward from the groove opening to the groove bottom.

[0025] The beneficial effects of this utility model are as follows:

[0026] The track designed in this utility model includes multiple sub-tracks, which facilitates transportation and handling and is easier to process. The ground mat assembly set under the track can adapt well to the ground. Even if the ground is uneven, the tilt angle of the support unit can be adjusted by adjusting the structure so that the support height of the support units on both sides of the sub-track is adapted to the ground undulations, ensuring that the sub-track is level and preventing the RGV mother-daughter vehicle from tilting when it is running.

[0027] The spherical sleeve designed in this invention, in conjunction with the spherical groove, can limit the position of the spherical sleeve, thereby constraining the position of one end of the adjusting rod. The other end of the adjusting rod is hinged to the protrusion through a ball joint seat. When the locking nut is rotated, the locking nut pushes the spherical sleeve to move, thereby driving the support plate to rotate around the hinge axis, changing the position and height of the pad to adapt to complex terrain. The main wheel groove supports the main wheels of the RGV mother-daughter vehicle, and the auxiliary wheel groove cooperates with the auxiliary wheels of the RGV mother-daughter vehicle to form a "three-wheel groove" structure, which distributes the load and prevents the RGV from derailing and overturning, thus improving operational stability.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1:

[0041] like Figures 1 to 8 As shown, Embodiment 1 of this utility model provides an RGV mother-daughter vehicle track structure that can be used in flat, hardened industrial plant environments. First, multiple shorter sub-tracks 1 are connected sequentially in a straight line to form a longer track. Two such tracks are laid in parallel. The main wheel groove 11 at the top of each sub-track 1 supports the main wheels of the RGV mother-daughter vehicle, while the symmetrical auxiliary wheel grooves 12 on both sides cooperate with the auxiliary wheels of the RGV mother-daughter vehicle, forming a "three-wheel groove" structure, effectively distributing the load and preventing the RGV from derailing and tipping over.

[0042] The two ends of multiple parallel cross braces 2 are respectively fixedly connected to the protrusions 13 of the two tracks by bolts. The waist-shaped through holes 131 opened on the protrusions 13 allow the cross braces 2 to be finely adjusted to a certain extent to accommodate positional errors during installation. The cross braces 2 can fix the two tracks relatively and maintain the stability of the track width.

[0043] Each sub-track 1 is fixed to the ground by multiple floor mat assemblies 3, and each floor mat assembly 3 includes two support units 31, supporting the bottom sides of the sub-track 1. Figure 4 As shown, the connecting plate 311 can be fixed to the lower part of the auxiliary wheel groove 12 with bolts. The support plate 312 is hinged to the connecting plate 311. A pad 3122 is fixed to the end of the support plate 312 away from the connecting plate 311. The pad 3122 can increase the support area, and a rubber pad can be placed under the pad 3122. By changing the tilt angle of the support plate 312 using the adjustment structure, the support position of the pad 3122 can be changed. The support plates 312 on the left and right sides can be adjusted separately, thereby adjusting the sub-track 1 to be level.

[0044] After installation, if a slight tilt is found in the track, the height of the foot 3122 can be changed by rotating the support plate 3122 around the hinge axis to make the track level. Finally, the foot 3122 is fixed to the ground by the expansion bolts passing through the positioning holes 3123 on the foot 3122 to ensure the track is stable.

[0045] Example 2:

[0046] Based on Embodiment 1, this utility model proposes a specific design for the adjustment structure. In this embodiment, the adjustment structure includes a ball joint seat 313, an adjusting rod 314, a spherical sleeve 315, and a locking nut 317. The ball joint seat 313 is fixed to the side of the protrusion 13 by multiple bolts, and the adjusting rod 314 is hinged to the protrusion 13 via the ball joint seat 313, allowing the adjusting rod 314 to rotate at multiple angles on the protrusion 13. Figure 7 and Figure 8 As shown, a through groove 3121 is provided on the support plate 312, and the end of the adjusting rod 314 away from the ball joint seat 313 passes through the through groove 3121 on the support plate 312.

[0047] like Figure 4 and Figure 8 As shown, a spherical sleeve 315 is fitted onto the adjusting rod 314 on the side of the support plate 312 away from the ball joint seat 313, so that it fits into the spherical groove 316 on the through groove 3121. Under the weight of the sub-track 1, the ball joint seat 313 pulls the adjusting rod 314 downward, causing the spherical sleeve 315 to press against the spherical groove 316, limiting the position of the spherical sleeve 315, thereby constraining the position of the adjusting rod 314 away from the ball joint seat 313. Then, a locking nut 317 is fitted onto the adjusting rod 314 on the side of the spherical sleeve 315 away from the support plate 312, and it is threaded into the adjusting rod 314.

[0048] When installing the RGV mother-daughter vehicle track on ground with a certain angle of inclination, observe the inclination of the sub-track 1, and rotate the locking nut 317. Since one end of the adjusting rod 314 is hinged to the protrusion 13 through the ball joint seat 313, and the other end is constrained by the spherical sleeve 315 and the spherical groove 316, the adjusting rod 314 pulls the support plate 312 under the push of the locking nut 317, causing it to rotate around the hinge axis, so that the support height of the support units 31 on both sides of the sub-track 1 adapts to the ground undulations. Continuously adjust the height of each support unit 31 until the track reaches a horizontal state, ensuring that the RGV mother-daughter vehicle will not tilt due to the ground inclination when traveling. Finally, use expansion bolts to fix the pads 3122 to the ground, so that the track is firmly fixed to the ground.

[0049] Example 3:

[0050] Based on Embodiments 1 and 2, the groove walls of the main wheel groove 11 and the auxiliary wheel groove 12 are designed to have a certain slope. For example... Figure 4 As shown, the groove walls of the main wheel groove 11 and the auxiliary wheel groove 12 gradually contract inward from the groove opening to the groove bottom, which can guide the wheels of the RGV mother and daughter car to automatically position themselves and reduce the risk of derailment.

[0051] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
