Description

Technical Field

[0001] This utility model relates to the field of mechanical transportation technology, and in particular to an AGV (Automated Guided Vehicle) trolley. Background Technology

[0002] In scenarios such as intelligent manufacturing, e-commerce warehousing, and electronic component production, automated guided vehicles (AGVs) serve as core equipment for achieving unmanned material handling and have become a key support for improving operational efficiency and reducing labor costs.

[0003] Existing AGVs are mainly divided into two categories: "trackless navigation type" and "rail-guided type". However, neither can adapt to complex layout requirements. Although trackless navigation AGVs do not require ground modification and can plan their own paths, their positioning accuracy is easily affected by indoor environmental interference. In addition, their turning radius is too large in narrow passages, making it impossible to efficiently shuttle between dense shelves. Rail-guided AGVs have fixed track layouts and can only move along preset paths (such as straight lines and fixed curves). If the work area needs to be adjusted (such as temporarily adding sorting stations), the guide rails need to be re-laid, resulting in extremely poor adaptability in indoor dynamic operation scenarios (such as temporarily adjusting sorting paths during e-commerce promotions). Utility Model Content

[0004] The purpose of this invention is to provide an AGV (Automated Guided Vehicle) to solve the technical problem of poor flexibility in the prior art.

[0005] To solve the above problems, the AGV trolley involved in this utility model adopts the following technical solution:

[0006] This utility model provides an AGV trolley, including a chassis, a traveling mechanism disposed on opposite sides of the chassis, and a lifting mechanism disposed on the chassis. The traveling mechanism includes a transmission part capable of reciprocating along the side wall of the chassis, a first drive part that drives and cooperates with the transmission part, and a working part that is hinged at equal intervals along the circumference of the transmission part and slides and is limited by the chassis. When the traveling mechanism passes through the I-beam track at equal intervals in sequence, the transmission part drives the working part to move circumferentially under the action of the first drive part. The adjacent working parts at its first end are sequentially clamped on both sides of the I-beam track, and the adjacent working parts at its tail end are sequentially disengaged from both sides of the I-beam track.

[0007] Preferably, a first slide rail is provided on the side wall of the chassis, extending circumferentially and forming a closed loop. The first slide rail includes two symmetrically arranged curved sections and two parallel straight sections located between the two curved sections. The two ends of the two curved sections correspond one-to-one with the ends of the adjacent straight sections and are smoothly connected. The transmission part is limited and slidably disposed in the first slide rail.

[0008] Preferably, the walking mechanism further includes a main sprocket and a secondary sprocket that are rotatably disposed on the side wall of the chassis at intervals. The first drive unit is connected to the main sprocket, and the transmission unit is a chain. The chain passes around the main sprocket and the secondary sprocket in sequence and then links the ends of the chain. The main sprocket is driven by the chain and the secondary sprocket.

[0009] Preferably, the two curved sections of the first slide are located on the inner side of the chain, and the main sprocket and the auxiliary sprocket are coaxially arranged with the two curved sections.

[0010] Preferably, the working part includes a connecting arm, a roller, a first guide wheel, and a second guide wheel. The roller, the first guide wheel, and the second guide wheel are rotatably mounted on the connecting arm. The first guide wheel is matched and mounted in the first slide rail. A second slide groove corresponding to the position of the chain is also opened on the side wall of the chassis. The second guide wheel is matched and mounted in the second slide rail.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model provides an AGV (Automated Guided Vehicle) trolley, including a chassis, a traveling mechanism disposed on opposite sides of the chassis, and a lifting mechanism disposed on the chassis. The traveling mechanism includes a transmission part capable of reciprocating along the side wall of the chassis, a first drive part that drives and cooperates with the transmission part, and working parts that are hinged at equal intervals along the circumference of the transmission part and slidingly cooperate with the chassis for limiting.

[0022] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] This utility model provides an AGV (Automated Guided Vehicle) trolley, as shown in the figure, including a chassis 1, a traveling mechanism disposed on opposite sides of the chassis 1, and a lifting mechanism 2 disposed on the chassis 1. The lifting mechanism 2 is used to suspend the equipment to be transported and adopts an existing mechanical structure, specifically an electric hoist. The traveling mechanism includes a transmission part capable of reciprocating along the side wall of the chassis 1, a first drive part that drives the transmission part, and working parts 4 that are hinged at equal intervals along the circumference of the transmission part and slidingly fitted to the chassis 1. When the traveling mechanism traverses the I-beam tracks 3 at equal intervals, the transmission part drives the working parts 4 to move circumferentially under the action of the first drive part. The adjacent working parts 4 at its first end are sequentially clamped on both sides of the adjacent I-beam track 3, and the adjacent working parts 4 at its tail end sequentially disengage from the sides of the I-beam track 3 they are clamped on, realizing continuous travel.

[0024] A first slide rail 5 extending circumferentially and forming a closed loop is provided on the side wall of the chassis 1. The first slide rail 5 includes two symmetrically arranged curved sections and two parallel straight sections located between the two curved sections. The two ends of the two curved sections correspond one-to-one with the ends of the adjacent straight sections and are smoothly connected (that is, the first end of one curved section is tangentially connected to the first end of one straight section, and the second end of the curved section is tangentially connected to the first end of the other straight section; the first end of the other curved section is tangentially connected to the tail end of one straight section, and the second end of the curved section is tangentially connected to the tail end of the other straight section, so that the two curved sections and the two straight sections together form a continuous and uninterrupted closed loop first slide rail 5). The transmission unit is limited and slidably disposed within the first slide rail 5.

[0025] The traveling mechanism also includes a main sprocket 6 and a secondary sprocket 7, which are rotatably mounted on the side wall of the chassis 1 at intervals. A first drive unit is connected to the main sprocket 6, and the transmission unit is a chain. The chain passes around the main sprocket 6 and the secondary sprocket 7 in sequence and then links them end to end. The main sprocket 6 is driven by the chain to the secondary sprocket 7. The first drive unit works to drive the main sprocket 6 to rotate, and the main sprocket 6 drives the secondary sprocket 7 to rotate through the chain. The two curved sections of the first slide rail 5 are located on the inner side of the chain, and the main sprocket 6 and the secondary sprocket 7 are coaxially mounted with the two curved sections.

[0026] The working part 4 includes a connecting arm 41, a roller 42, a first guide wheel 43, and a second guide wheel 44. The roller 42, the first guide wheel 43, and the second guide wheel 44 are rotatably mounted on the connecting arm 41. The first guide wheel 43 is matched and mounted in the first slide rail 5 (the inner sidewall of the first slide rail 5 laterally limits the first guide wheel 43 so that it can only slide along the direction of the first slide rail 5). The sidewall of the chassis 1 is also provided with a second slide groove corresponding to the position of the chain. The second guide wheel 44 is matched and mounted in the second slide rail 8 (the inner sidewall of the second slide rail 8 laterally limits the second guide wheel 44 so that it can only slide along the direction of the second slide rail 8). The roller 42 and the first guide wheel 43 are respectively located on both sides of the second guide wheel 44. When the working part 4 moves to the straight section of the first slide rail 5, the axis of the roller 42 is parallel to the straight section of the first slide rail 5. The rollers 42 in any adjacent working sections 4 have the same direction, while the rollers 42 in adjacent working sections 4 have opposite directions. The connecting arm 41 is connected to the connecting shaft of the two chain links of the chain. In the above, the second guide wheel 44 is rotatably mounted on the connecting shaft that passes through the connecting arm 41 and enters the second slide groove.

[0027] This device also includes a lifting unit mounted on the chassis 1, a roller 10 rotatably mounted on the lifting unit, and a second drive unit mounted on the lifting unit for driving the roller 10 to rotate. These components work in conjunction with the traveling mechanism to stabilize the vehicle body and adjust the contact state between the roller and the track. The lifting unit can move the roller 10 away from or towards the chassis 1, cooperating with the traveling mechanism to bring the roller 10 into contact with or release it from the I-beam track 3. The lifting unit has two rollers 10, which are inclined at an acute angle to each other. Both the first and second drive units are motors.

[0028] The working process of this device is as follows: Through preset guidance, the initial position of the working part is aligned with the starting I-beam track. The first drive unit drives the main sprocket to rotate. The main sprocket drives the secondary sprocket to rotate synchronously through the chain. The chain drives the working part to move along the first slide and the second slide. The first guide wheel slides in the first slide and the second guide wheel slides in the second slide, restricting the movement direction of the working part. The adjacent working parts at the beginning are clamped to both sides of the adjacent I-beam track in turn because the rollers alternate in opposite directions. The adjacent working parts at the end move with the chain and disengage from the original clamped sides of the track in turn, realizing continuous alternation and pushing the trolley to move forward along the track.

[0029] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
