[0033] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] See also Figure 1 , Figure 2 The transport platform provided in this embodiment includes a bridge deck 100 , a rotating mechanism 200 , a conveying mechanism 300 and an auxiliary supporting mechanism 400 .

[0035] There are multiple bridge decks 100, and the multiple bridge decks 100 are connected and rotated in sequence along the extension direction of the bridge decks 100. The slewing mechanism 200 includes a driving member 210, and the slewing mechanism 200 is arranged between two adjacent bridge decks 100 to drive the bridge deck 100 to flip vertically along the connection. The conveying mechanism 300 is arranged on the bridge deck 100, and the conveying direction of the conveying mechanism 300 is the same as the extension direction of the multiple bridge decks 100. The auxiliary support mechanism 400 is arranged at the bottom of the bridge deck 100, and the auxiliary support mechanism 400 extends in the vertical direction and slidably cooperates with the bridge deck 100.

[0036] When in use, the bridge deck 100 at the end is connected to the transport vehicle. When the transport vehicle reaches the pickup or placement position, the rotating mechanism 200 is driven to flip the multiple bridge decks 100 until all the bridge decks 100 are in the same horizontal plane to form an extended bridge body.

[0037] The conveying mechanism 300 takes the workpiece along the long bridge body to the transport vehicle or to the processing equipment. In the process of taking and delivering the workpiece, the auxiliary support mechanism 400 can provide auxiliary support for the bridge deck 100 to prevent the middle part of the long bridge body from collapsing and being damaged. After use, the rotating mechanism 200 is driven to flip multiple bridge decks 100 to the top of the bridge deck 100 at the end without taking up too much space.

[0038] The transport platform provided in this embodiment is formed into a long bridge body by overlapping multiple bridge decks 100 to increase the pick-up and delivery distance, and the multiple bridge decks 100 can be flipped after use, thereby meeting the transportation of workpieces during processing without occupying too much space, and is very convenient to use.

[0039] In this embodiment, a rotating shaft 110 is provided at one end of the bridge deck 100, and a rotating hole is provided at the other end. The rotating shaft 110 extends along the width direction of the bridge deck 100. There are multiple bridge decks 100, and the multiple bridge decks 100 are rotatably connected through the rotating shaft 110 and the rotating hole. The driving end of the driving member 210 is drivingly connected to the rotating shaft 110.

[0040] The plurality of bridge decks 100 are connected by the rotation shaft 110 and the rotation hole. Specifically, the driving member 210 in this embodiment is a driving motor, which is installed on one side of the rotation hole and is transmitted by the rotation shaft in the rotation hole through gears. When in use, the driving motor drives the rotation shaft to rotate through the gears, so that the bridge deck 100 with the rotation shaft is turned along the rotation shaft until the bridge deck 100 is horizontal, and the driving motor stops running and is locked, thereby completing the horizontal setting of the bridge deck 100.

[0041] As an implementable method, the drive motor can also be replaced by a cylinder drive or a hydraulic drive. Taking the cylinder drive as an example, under this structure, a mounting column extending in the vertical direction can be set on a bridge body, one end of the cylinder is hinged to the mounting column, and the other end is hinged to the connected bridge body. When the cylinder is extended, the two bridge bodies are turned inward under the drive of the cylinder, and when the cylinder is retracted, the two bridge bodies are turned out to the horizontal, which can also realize the turning and resetting of the bridge body.

[0042] In this embodiment, the conveying mechanism 300 includes a conveying chain 310. A chain groove 120 is provided on the bridge deck 100. The extension direction of the chain groove 120 is the same as the extension direction of the bridge deck 100. The chain grooves 120 on multiple bridge decks 100 are connected to form a placement groove. The conveying chain 310 is arranged in the placement groove.

[0043] The chain is placed in the placement groove to prevent the chain from being exposed and to prevent the chain from being damaged due to excessive load. Specifically, when the chain is used to pick up and deliver the workpiece, a clamp or a magnetic device can be connected to the end of the chain, and the clamp or the magnetic device can be driven to move by the chain, and the workpiece can be clamped or adsorbed and then driven to move together.

[0044] In this embodiment, a limiting member 130 is disposed on the bridge deck 100. The limiting member 130 is covered on the placement groove.

[0045] The limiter 130 is arranged on the mounting groove. When the bridge deck 100 rotates, the limiter 130 can press the chain to prevent the chain from tilting out or falling off due to the rotation of the bridge deck 100, thereby ensuring that the chain can be stably placed in the mounting groove and will not fall off or become disordered due to the flipping of the bridge deck 100.

[0046] The stopper 130 in this embodiment is a blocking paddle. The blocking paddle has a rotation axis, which is arranged in the chain slot 120, so that the blocking paddle can rotate in the same direction as the bridge deck 100 flipping, thereby ensuring that the blocking paddle can rotate with the bridge deck 100. The blocking paddle is located at the connection between the two bridge decks 100 and when the bridge deck 100 flips, the blocking paddle can rotate 90° together to prevent the blocking paddle from getting stuck and damaging the equipment when the bridge deck 100 rotates.

[0047] In this embodiment, the auxiliary support mechanism 400 includes a locking member 410 and a supporting member 420. The locking member 410 is slidably matched with the bridge deck 100 and can lock the bridge deck 100. The top end of the supporting member 420 is hinged to the locking member 410, and the supporting member 420 extends in the vertical direction.

[0048] Specifically, the locking member 410 is used to slide on the bridge deck 100. When the bridge deck 100 is extended or moved in the same direction as the extension of the bridge deck 100, the locking member 410 moves with the bridge deck 100. If the bridge deck 100 needs to be extended into a processing device, the bottom of the locking member 410 and the support member 420 move along the bridge deck 100 under the push of the processing device to adjust the support position. After stopping the movement, the locking member 410 locks the bridge deck 100 and fixes the support position. The support member 420 supports the locking member 410 and the bridge deck 100. The locking member 410 can slide along the extension direction of the bridge deck 100 to prevent the locking member 410 from colliding with the processing device when the bridge deck 100 is extended into the processing device, causing damage to the device.

[0049] In this embodiment, guide members are provided on both sides of the bridge deck 100. The extension direction of the guide member is the same as the extension direction of the bridge deck 100, and a limiting portion is provided on the guide member. The locking member 410 has a slide groove, and an elastic limiting member 130 is provided in the slide groove. The slide groove and the guide member are slidably matched, and the elastic limiting member 130 is clamped with the limiting portion.

[0050] The guide piece and the slide groove are slidably matched to enable the locking piece 410 to slide along the extension direction of the guide piece. The guide pieces are connected to the limiter on both sides of the bridge deck 100, thereby achieving two-point support for the bridge deck 100 and making the bridge deck 100 more stable. After the limiter is engaged with the elastic limiter 130, the position of the locking piece is fixed to prevent the auxiliary support mechanism 400 from moving in series.

[0051] Furthermore, when the auxiliary support mechanism 400 is pushed, the elastic limit member 130 is compressed and comes out of the limit portion, and the locking member slides. After the locking member stops sliding, the elastic limit member 130 performs restorative deformation to engage with the limit portion again to achieve limitation.

[0052] In this embodiment, the guide member includes a plurality of pulleys 140. The rotating shaft of the pulley 140 extends in the horizontal direction, and a limiting hole is provided on the side of the pulley 140. The plurality of pulleys 140 are arranged at intervals along the extension direction of the bridge deck 100. The elastic limiting member 130 includes an elastic portion and a limiting portion, one end of the elastic portion is provided in the slide groove, and the other end is connected to the limiting portion, the limiting portion is a convex curved surface structure, and the limiting portion is adapted to the limiting hole.

[0053] Multiple pulleys 140 are arranged at intervals on the side of the bridge deck 100 along the extension direction of the bridge deck 100 to form a guide member. A limiting hole is provided on the side of each pulley 140, and a slide groove is buckled on the pulley 140. The locking member 410 can slide along the setting direction of the multiple pulleys 140.

[0054] Specifically, the limiting part in this embodiment is a limiting bead, the diameter of the limiting bead is larger than the diameter of the limiting hole, and the elastic part is a spring, one end of the spring is connected to the bottom of the slide groove, and the other end is connected to the limiting bead. When the locking member 410 stops moving, the spring stretches to push the limiting bead into the limiting hole, and when the locking member 410 is pushed and moves, the locking member 410 pulls the spring to move so as to pull the limiting bead out of the limiting hole.

[0055] In this embodiment, the support member 420 is a telescopic member, and a sensor 430 is disposed at the bottom of the telescopic member.

[0056] Specifically, the telescopic part in this embodiment is a pneumatic telescopic part, which is arranged in the vertical direction. The end of the pneumatic telescopic part moves in the vertical direction. The sensor 430 at the bottom of the pneumatic telescopic part can detect the distance from the ground. After the bottom end of the pneumatic telescopic part abuts the ground, the sensor 430 is triggered to stop the pneumatic telescopic part from extending.

[0057] In this embodiment, a support tube 440 is provided at the bottom of the support member 420. The support member 420 includes a telescopic portion and a connecting portion, the connecting portion is provided at the end of the telescopic portion, the outer diameter of the connecting portion is larger than the telescopic portion, an elastic member is connected to the bottom of the connecting portion, and the elastic member is connected to the sensor 430. A light hole is provided at the top of the support tube 440, the light hole is slidably matched with the telescopic portion, and the support tube 440 is sleeved outside the connecting portion and the sensor 430.

[0058] The support tube 440 is sleeved on the outside of the sensor 430 and the connecting part to prevent the sensor 430 and the connecting part from being damaged due to collision when following the movement. Specifically, the sensor 430 in this embodiment is a pressure sensor 430. When the pneumatic telescopic part is extended, the connecting part drives the pressure sensor 430 and the elastic part to move downward together. After the bottom of the pressure sensor 430 touches the ground, the pneumatic telescopic part continues to extend to compress the elastic part. After the pressure on the pressure sensor 430 reaches a preset value, the pneumatic telescopic part is controlled to stop moving and extending, thereby applying prestress to the pneumatic telescopic part to ensure stable bearing and delivery of the workpiece.

[0059] The transport vehicle provided in this embodiment includes a vehicle body and a transport platform. The transport vehicle includes a mounting slot, in which a driving mechanism is provided. The transport platform is provided in the mounting slot, and the driving mechanism is transmission-connected to the transport platform, and the driving mechanism is used to drive the transport platform to extend out of the mounting slot or to be retracted into the mounting slot.

[0060] Specifically, the driving mechanism in this embodiment is a driving motor cooperated with a screw transmission structure. The conveying platform is connected to the screw transmission structure and moves along the length direction of the screw in the screw transmission structure under the drive of the driving motor, thereby realizing the movement of extending the conveying platform from the installation slot or retracting it into the installation slot.

[0061] Furthermore, in this embodiment, the screw transmission structure includes two screws, and the driving motor is transmission-connected to the two screws via gears, and the two screws are respectively connected to two sides of the conveying platform, thereby realizing stable movement of the conveying platform.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
