Description

Technical Field

[0001] This application relates to the technical field of AGV lanes, and in particular to an AGV lane floor structure. Background Art

[0002] AGV refers to a transport vehicle equipped with automatic guiding devices such as electromagnetic or optical devices, which can travel along a specified guiding path on an AGV lane and has safety protection and various transfer functions, belonging to the category of wheeled mobile robots. Generally, the transportation requirements of AGVs are very demanding. For example, when using an AGV to transport glass substrates, if the AGV vibrates during transportation, it may cause damage to the glass substrates and result in great losses. The transportation requirements for AGVs include not only the requirements for the AGV itself but also the requirements for the AGV lane.

[0003] The existing AGV lane structures generally include three types: elevated floor structure, epoxy floor structure, and reinforced concrete floor (hereinafter referred to as RC floor) paved with stainless steel plates. Among them, making an elevated floor has high space requirements. In the case where the space requirements for making an elevated floor are not met, one has to settle for the epoxy floor structure or the RC floor paved with stainless steel plates. The epoxy floor structure is a structure formed by laying epoxy mortar on an RC floor, which can meet the flatness requirements of the AGV lane during design and manufacture. However, due to the excessive weight of the AGV itself, the epoxy floor structure will be damaged after long-term use. For the reinforced concrete floor paved with stainless steel plates, the stainless steel plates are relatively less likely to be damaged compared with the epoxy floor structure. However, with the increase in the number of uses, delamination may occur between the stainless steel plates and the floor, affecting the stable transportation of AGV vehicles. Therefore, further improvement is needed. Summary of the Utility Model

[0004] In order to reduce the damage to the ground under the load-bearing handling of AGV cars while improving the transportation stability of AGV cars, this application provides an AGV lane floor structure.

[0005] An AGV lane floor structure provided by this application adopts the following technical solutions:

[0006] An AGV lane floor structure includes a stainless steel base laid on a concrete ground. The stainless steel base is provided with base side edges at intervals along its width direction, and a laying gap is formed between the base side edges. A second leveling layer and a stainless steel plate adhered to the second leveling layer are sequentially arranged in the laying gap from bottom to top. The stainless steel plate is used as the walking track for AGV cars, and a floor layer is laid on the outside of the base side edges of the stainless steel base on the concrete ground.

[0007] By adopting the above technical solutions, a stainless steel base is provided, which provides a rigid connection foundation for the stainless steel plate, plays a positioning effect on the stainless steel plate, reduces the possibility of relative slip between the stainless steel plate and the ground, and improves the installation stability of the stainless steel plate. When the stainless steel is subjected to the force after being pressed by the AGV cart, the force is transmitted to the stainless steel plates on both sides to improve the load dispersion ability of the stainless steel plates. At the same time, a second leveling layer is provided in the stainless steel base for leveling, which improves the installation flatness of the stainless steel plate, also provides a load dispersion effect for the stainless steel plate, improves the load capacity of the lane, reduces the damage to the lane during the load-bearing transportation of the AGV cart, and can also improve the transportation stability of the AGV cart. The floor layer provided on the outer side of the stainless steel base provides support for the side of the stainless steel base to improve the installation stability of the stainless steel base, and further improves the running stability of the AGV cart on this walking track.

[0008] Preferably, the upper surfaces of the stainless steel plate, the stainless steel base, and the floor layer are flush with each other.

[0009] By adopting the above technical solutions, after reducing the height difference between the stainless steel plate, the stainless steel base, and the floor layer, when the upper end of the stainless steel plate is pressed, it forces the stainless steel base to move in the direction away from each other, so as to reduce the possibility of the stainless steel plate slipping off, or the possibility of vibration when the AGV cart slips off the stainless steel plate during driving, so as to further improve the running stability of the AGV cart on the walking track.

[0010] Preferably, the floor layer is an inorganic silicon crystal floor layer.

[0011] By adopting the above technical solutions, since floor materials such as inorganic silicon crystals have characteristics such as high bearing capacity, high wear resistance, high flatness, and aesthetics, it can improve the aesthetics of the set lane floor while reducing the damage to the lane during the load-bearing transportation of the AGV cart.

[0012] Preferably, the second leveling layer successively includes an interface agent layer and an epoxy mortar layer from bottom to top.

[0013] By adopting the above technical solutions, the set interface layer is used to improve the adhesion between the subsequent epoxy mortar layer and the concrete floor, so as to reduce the possibility of the subsequent epoxy mortar falling off.

[0014] Preferably, expansion bolts are provided through the stainless steel plate, and the expansion bolts are threadedly connected to the second leveling layer.

[0015] By adopting the above technical solutions, by providing expansion bolts, the fixing effect with the second leveling layer is further improved.

[0016] Preferably, the concrete floor is provided with a slot for inserting the stainless steel base.

[0017] By adopting the above technical solution, the stainless steel base can be pre-positioned, reducing the possibility of relative sliding of the stainless steel base during the pouring of the second leveling layer and the floor layer, so as to ensure the horizontal straightness of the subsequent stainless steel plate, that is, improve the quality of the laid lane floor structure.

[0018] Preferably, the stainless steel base includes two side plates and a connecting strip arranged between the two side plates, and a plurality of connecting strips are arranged at intervals along the length direction of the side plates.

[0019] By adopting the above technical solution, if two side plates form the stainless steel base, during the pouring of the second leveling layer and the floor layer, the two side plates may be pushed to bulge away from each other or concave towards each other, or during the subsequent load-bearing handling of the AGV cart, the load borne by the side plates may force the side plates to bulge away from each other. Therefore, by providing a connecting strip and arranging a plurality of connecting strips at intervals along the length direction of the side plates, the connection strength between the two side plates can be improved, thereby improving the installation stability of the stainless steel base for the stainless steel plate.

[0020] Preferably, a first leveling layer is arranged between the two side plates and laid on the connecting strip.

[0021] By adopting the above technical solution, due to the set connecting strip, there is a certain height difference between it and the concrete floor. If the second leveling layer is directly laid, it may force the stainless steel base to have the possibility of top-to-bottom sliding with the concrete floor, and then the subsequent load-bearing capacity may be reduced. Therefore, before laying the second leveling layer, the first leveling layer is laid first to adjust the position of the stainless steel base.

[0022] Preferably, a bolt is inserted through the connecting strip, and the bolt is threadedly connected to the concrete floor.

[0023] By adopting the above technical solution, by using bolts, the connection strength between the stainless steel base and the concrete floor can be further improved.

[0024] Preferably, a bolt is inserted through the side plate, the bolt is threadedly connected with nuts, two nuts are provided and respectively abut against the opposite side walls of the side plate, and both ends of the bolt extend into the second leveling layer and the floor layer respectively.

[0025] By adopting the above technical solution, bolts extending into the second leveling layer and the chassis layer are provided. The bolts and nuts are installed on the side plates before pouring the floor layer and the second leveling layer. After installation, the subsequent pouring of the second leveling layer and the floor layer is started. After the second leveling layer and the floor layer solidify, the connection strength between the side plates and the second leveling layer and the floor layer is improved, the possibility of subsequent slippage and detachment of the side plates is reduced, and the installation stability of the subsequent stainless steel plates is improved.

[0026] In summary, the present utility model has the following beneficial effects:

[0027] By providing a stainless steel base, a rigid connection foundation is provided for the stainless steel plate, which plays a positioning effect on the stainless steel plate, reduces the possibility of relative slippage between the stainless steel plate and the ground, and improves the installation stability of the stainless steel plate. Moreover, when the stainless steel is subjected to the force after being pressed by the AGV cart, the force is transmitted to the stainless steel plates on both sides, so as to improve the load dispersion ability of the stainless steel plates. At the same time, a second leveling layer is provided in the stainless steel base for leveling, which improves the installation flatness of the stainless steel plates, also provides a load dispersion effect for the stainless steel plates, improves the load capacity of the lane, and reduces the damage to the lane during the load-bearing transportation of the AGV cart. The floor layer provided outside the stainless steel base provides support for the side of the stainless steel base, so as to improve the installation stability of the stainless steel base, and further improve the running stability of the AGV cart on this walking track.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will further describe the present application in detail Figures 1-4 in conjunction with the attached

[0034] The embodiments of the present application disclose an AGV lane floor structure.

[0035] Embodiment 1:

[0036] An AGV lane floor structure, referring to Figure 1 、 Figure 2 , includes two stainless - steel bases 1 laid on the concrete ground and arranged oppositely. A number of stainless - steel bases 1 are arranged at intervals along the length direction of the concrete ground. Base side edges 11 are arranged at intervals along the width direction of the stainless - steel base 1. A laying gap 12 is formed between the base side edges 11. A first leveling layer 2, a second leveling layer 3, a second bonding layer 4, and a stainless - steel plate 5 are sequentially arranged in the laying gap 12 from bottom to top.

[0037] Referring to Figure 2 、 Figure 3 , in this embodiment, the height h1 of the stainless - steel base 1 ranges from 2 cm to 3 cm, specifically 2.5 cm high. The stainless - steel base 1 specifically includes two symmetrically arranged side plates 13 and a connecting strip 14 fixedly connected between the side plates 13. The distance w1 between the two side plates 13 is specifically 12 cm, so that the width of a single track for the AGV vehicle to travel is 12 cm. Among them, the opposite two surfaces of the side plate 13 form the base side edge 11. A number of connecting strips 14 are arranged at intervals along the length direction of the side plate 13. A bolt 141 is penetrated through the middle of the connecting strip 14. The bolt 141 is specifically a countersunk head bolt 141, and the countersunk head bolt 141 is threadedly connected to the concrete ground to further improve the connection strength between the stainless - steel base 1 and the concrete ground. It should be noted that the bolt 141 can be installed after the first bonding layer 6, or after the first bonding layer 6 and the first leveling layer 2, specifically set according to requirements.

[0038] Furthermore, bolts 141 are also penetrated through the side plate 13. The bolts 141 are arranged at intervals along the length direction of the side plate 13 and are staggered with the connecting strip 14. The bolt 141 is threadedly connected with a nut 142. Two nuts 142 are provided and respectively abut against the opposite two side walls of the side plate 13. The operation of installing the bolt 141 and the nut 142 on the side plate 13 can be carried out before the first bonding layer 6, that is, when assembling the stainless - steel base 1, or after the first bonding layer 6, specifically set according to requirements. It should be noted that in this embodiment, the bolt 141 is a long bolt 141 and is exposed on the opposite two side walls of the side plate 13. When pouring the floor layer 7 and the second leveling layer 3, at this time, both ends of the bolt 141 extend into the second leveling layer 3 and the floor layer 7 respectively, to improve the connection strength and stability between the side plate 13 and the floor layer 7 and the second leveling layer 3, and further improve the installation stability of the installed stainless - steel plate 5.

[0039] Furthermore, in order to reduce the possibility of relative slippage of the stainless steel base 1 under pressure during the subsequent pouring of the first leveling layer 2 and the second leveling layer 3, the concrete floor is provided with a slot for the stainless steel base 1 to be inserted, specifically for the side panel 13 to be inserted, and the depth of the slot is 2 mm, which plays a pre-positioning role for the stainless steel base 1. Before the side panel 13 is inserted into the corresponding slot, the connecting strip 14 and the surface of the side panel 13 close to the concrete floor are coated with epoxy adhesive. At this time, the height of the epoxy mortar applied is about 1 mm, and then they are bonded to the concrete floor and the slot respectively. When the epoxy adhesive solidifies, a first bonding layer 6 is formed. Then, the epoxy mortar is applied to cover the connecting strip 14, and after solidification, the first leveling layer 2 is formed to fix the stainless steel base 1. It should be noted that the height of the applied epoxy mortar is about 2 mm.

[0040] Then, the second leveling layer 3 is poured to level the stainless steel plate 5. In this embodiment, the second leveling layer 3 includes an interface agent layer 31 and an epoxy mortar layer 32 from bottom to top, wherein the interface agent is applied by spraying or rolling, and forms an interface agent layer 31 after solidification, which is mainly used to ensure that the bottom wall of the paving gap 12 is completely closed, and to improve the bonding force between the subsequent epoxy mortar layer 32 and the first leveling layer 2. In this embodiment, the epoxy mortar layer 32 is specifically poured by solvent-free epoxy mortar. It should be noted that during the pouring of the solvent-free epoxy mortar, a 1 cm high space needs to be reserved between the stainless steel base 1 for the installation of the stainless steel plate 5.

[0041] Before laying the stainless steel plate 5, a floor layer 7 is first laid on the concrete ground on the outside of the base side 11 of the stainless steel base 1. The laid floor layer 7 is arranged flush with the upper surface of the stainless steel base 1. In this embodiment, the floor layer 7 is specifically an inorganic silicon crystal floor layer 7, because it has the characteristics of high bearing capacity, high wear resistance, high flatness and aesthetics.

[0042] After the inorganic silicon crystal floor layer 7 solidifies and is polished, epoxy adhesive is applied to the upper surface of the second leveling layer 3 and the lower surface of the stainless steel plate 5, and they are bonded together. After the epoxy adhesive solidifies, a second adhesive layer 4 is formed to fix the stainless steel plate 5 in the stainless steel base 1. In this embodiment, the height of the stainless steel plate 5 is about 8 mm. It should be noted that the stainless steel plate 5 is set as flush as possible with the upper surface of the stainless steel base 1 to reduce the possibility of vibration due to the height difference when the AGV vehicle is driving on the lane.

[0043] In this embodiment, the stainless steel plate 5 is provided with perforations extending therethrough. A plurality of perforations are arranged at intervals along the length direction of the stainless steel plate 5, specifically three perforations are provided. The stainless steel plate 5 is provided with expansion bolts 51 inserted through the perforations. The expansion bolts 51 are threadedly connected to the second leveling layer 3. It should be noted that the expansion bolts 51 are countersunk. And in order to reduce the possibility of rusting when exposed to the outside, in this embodiment, sealant can be applied to the expansion bolts 51 to achieve a sealing effect and make the surface of the stainless steel plate 5 relatively smooth.

[0044] The implementation principle of an AGV lane floor structure according to an embodiment of the present application is as follows: By providing the stainless steel base 1, a rigid connection foundation is provided for the stainless steel plate 5 to position the stainless steel plate 5, reducing the possibility of relative slippage between the stainless steel plate 5 and the ground and improving the installation stability of the stainless steel plate 5. And when the stainless steel is subjected to the force after being pressed by the AGV cart during formation, the force is transmitted to the stainless steel plates 5 on both sides to improve the load dispersion ability of the stainless steel plates 5. At the same time, the second leveling layer 3 is provided in the stainless steel base 1 for leveling, improving the installation flatness of the stainless steel plate 5 and also providing a load dispersion effect for the stainless steel plate 5, improving the load capacity of the lane, reducing the damage to the lane during the load-carrying transportation of the AGV cart and at the same time improving the transportation stability of the AGV cart. The floor layer 7 provided outside the stainless steel base 1 provides support for the side surface of the stainless steel base 1 to improve the installation stability of the stainless steel base 1, and further improves the running stability of the AGV cart on this walking track.

[0045] Embodiment 2:

[0046] Refer to Figure 4 , the difference from Embodiment 1 is that the length direction of the connecting strip 14 is inclined to the length direction of the side plate 13, and adjacent connecting strips 14 are connected to each other. A plurality of connecting strips 14 are distributed in a zigzag shape along the length direction of the stainless steel base 1. At this time, the bolts 141 provided on both sides of the stainless steel base 1 are arranged staggeredly.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
