Description

Technical Field

[0001] The present invention belongs to the field of automation technology, and particularly relates to an RGV transport vehicle and method for tower parts. Background Art

[0002] In today's transmission line tower manufacturing industry, the logistics transportation link of steel pipe components mostly follows the traditional manual overhead crane operation mode. This outdated transportation method has increasingly prominent drawbacks due to its deep binding to the conventional manual operation process.

[0003] On the one hand, the operator needs to constantly control the operation of the overhead crane. From lifting, moving to accurately placing the steel pipe components, each step depends on manual judgment and manual operation. A slight mistake will cause deviation, resulting in the transportation efficiency always remaining at a low level and being difficult to meet the needs of modern large-scale and fast-paced production.

[0004] On the other hand, the complexity and high intensity of manual operation bind a large amount of manpower to the transportation post. Not only is the labor cost high, but also the long-term repetitive labor is prone to operation fatigue, further increasing the probability of errors and causing double waste of time and resources. Over time, this inefficient transportation mode has become a major bottleneck restricting the transmission line tower manufacturing industry from moving towards high-efficiency and automated production.

It should be understood that these descriptions are exemplary and do not limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0035] An RGV transport vehicle for tower components provided by the present invention includes an X track 3, at least one Y track 4 with one end connected to the X track 3, a mother vehicle 2 moving on the X track 3, and a sub-vehicle 1 detachably installed on the mother vehicle 2. The sub-vehicle 1 corresponds to the Y track 4, realizing that the mother vehicle drives the sub-vehicle to move in the X direction. When it is necessary to move on the Y track, the sub-vehicle is separated from the mother vehicle and the sub-vehicle moves onto the Y track.

[0036] A connection code is provided at the connection of the X track 3 and the Y track. The connection code is installed on the ground. A code scanning component 26 corresponding to the connection code is provided on the mother vehicle 2. The code scanning component 26 transmits the in-place signal to the control system. After receiving the in-place signal, the control system controls the stop of the mother vehicle drive unit 24 and the start of the sub-vehicle drive unit 14. When the code scanning component 26 of the mother vehicle 2 scans the connection code, the mother vehicle stops, and its sub-vehicle moving track 22 corresponds to the Y track 4. The sub-vehicle 1 moves from the sub-vehicle moving track 22 onto the Y track 4 to realize the movement in the Y direction.

[0037] The mother vehicle 2 includes a vehicle body 21. A concave installation groove 27 for the sub-vehicle 1 is formed at the center of the top of the vehicle body 21. A first sub-vehicle positioning component 28 is provided on the installation groove 27. A sub-vehicle moving track 22 is provided on the vehicle body 21. When the mother vehicle 2 moves to a position corresponding to the Y track 4, the sub-vehicle moving track 22 matches the Y track 4, and the sub-vehicle 1 can reciprocally move from the sub-vehicle moving track and the Y track.

[0038] An energizing component 24 is provided on the vehicle body 21. The energizing component 24 corresponds to the X track 3 in the form of a sliding contact wire. The contact of the energizing component 24 is installed on the vehicle body 21, and the sliding wire is installed on the track on the ground. The code scanning component 26 is installed at the bottom of the vehicle body. Mother vehicle traveling wheels 23 that rotate under the action of a mother vehicle drive unit 25 are provided on the vehicle body. The mother vehicle traveling wheels 23 correspond to the X track 3. Driven by the mother vehicle drive unit 25, the mother vehicle traveling wheels 23 move, realizing the movement of the mother vehicle on the X track.

[0039] The sub-vehicle 1 includes a moving base 11, on which there are sub-vehicle traveling wheels 12 that move under the action of a sub-vehicle driving unit 14. The sub-vehicle traveling wheels 12 correspond to a sub-vehicle moving track 22 and a Y track 4. On the moving base 11, there is a second sub-vehicle positioning component 13 corresponding to a first sub-vehicle positioning component 28. At one end of the Y track 4 away from the X track 3, there is an anti-disengagement baffle to prevent the sub-vehicle from disengaging from the Y track. On the Y track 4, there is a third sub-vehicle positioning component corresponding to the second sub-vehicle positioning component 13. The settings of the first sub-vehicle positioning component and the third sub-vehicle positioning component can respectively ensure that when the sub-vehicle moves, it moves into place when moving onto the mother vehicle and moves into place when moving on the Y track.

[0040] The moving base 11 is provided with a lifting component 15.

[0041] The lifting component 15 includes a lifting motor 5. The driving end of the lifting motor 5 is meshed with the screw of a lifting screw rod 6. The top of the lifting screw rod 6 is connected to a lifting plate. Under the action of the lifting motor 5, the lifting screw rod 6 is driven to lift relative to a screw rod seat, and the screw rod seat is fixedly installed on the moving base 11. The lifting component further includes a guiding base and a guiding rod slidably installed in the guiding base.

[0042] The sub-vehicle 1 is provided with a clamping component 16 corresponding to the pipe tower. The clamping component 16 is installed on a lifting plate 113. The clamping component 16 includes at least two clamping units. During the clamping process, the multiple clamping units can ensure the stable movement of the pipe tower components. Each clamping unit includes a horizontally arranged fixed clamping plate 163. On the fixed clamping plate 163, there is a first pipe tower support base 164. On the fixed clamping plate 163, there is a vertically arranged support plate 162. On the support plate 162, there is a track for facilitating the up and down movement of a moving clamping plate 161. On the moving clamping plate 161, there is a second pipe tower support base corresponding to the first pipe tower support base 164. The moving clamping plate moves vertically on the support plate under the action of a clamping driving unit. The clamping driving unit includes a clamping screw rod. The clamping screw rod is rotatably installed on the support plate. The moving clamping plate is fixedly connected to a screw rod seat, and the screw rod fixed seat is screwed with the clamping screw rod. The clamping screw rod is connected to a clamping motor.

[0043] When it is necessary to clamp the pipe tower components, the sub-vehicle drives the clamping component to move. The pipe tower components are placed between the fixed clamping plate and the moving clamping plate. The lifting component drives the fixed clamping plate to rise, thereby lifting the pipe tower components. The moving clamping plate descends to fix the pipe tower components between the moving clamping plate and the fixed clamping plate, realizing the clamping of the pipe tower components.

[0044] When it is necessary to lower the tower component, the sub - vehicle drives the clamping component and the tower component on the clamping component to move to the placement position. The moving clamping plate rises, and the lifting component drives the fixed clamping plate to descend, so as to realize the lowering of the tower component to the placement support frame.

[0045] The support grooves of the first tower support base 164 and the second pipeline support base are V - shaped, which better match the circular pipe wall of the tower component and prevent displacement during the movement.

[0046] The moving base 11 includes a U - shaped support shell and a reinforcing rib 112 arranged in the insertion groove of the U - shaped support shell, which can avoid other equipment mechanisms for supporting materials to a certain extent when taking and placing materials.

[0047] First, the mother vehicle 2 stops at the starting position of the X - track 3. The sub - vehicle 1 is installed in the installation groove 27 of the mother vehicle 2. The first sub - vehicle positioning component 28 and the second sub - vehicle positioning component 13 ensure that the sub - vehicle 1 is installed in place. The power - on component 24 of the mother vehicle 2 obtains power from the ground track through the sliding contact line, and the code - scanning component 26 is in a standby state. Then, under the command of the control system, the mother vehicle 2 drives the mother vehicle traveling wheel 23 to move along the X - track 3 through the mother vehicle driving unit 25, driving the sub - vehicle 1 to move in the X - direction to the target position. When the code - scanning component 26 of the mother vehicle 2 scans the connection code at the connection of the X - track 3 and the Y - track 4, the control system receives the positioning signal and controls the mother vehicle driving unit 25 to stop. Then, the control system drives the sub - vehicle driving unit 14 to start working. The sub - vehicle 1 separates from the sub - vehicle moving track 22 of the mother vehicle 2 and moves onto the Y - track 4. The sub - vehicle 1 moves along the Y - track 4 to the target position through the sub - vehicle traveling wheel 12, and the third sub - vehicle positioning component ensures that the sub - vehicle 1 moves in place on the Y - track 4. After that, the sub - vehicle 1 drives the clamping component 16 to move to the placement position of the tower component, and the clamping component 16 completes the clamping of the tower component through the lifting component 15 and the clamping driving unit. The sub - vehicle 1 transports the clamped tower component along the Y - track 4 to the target position. Finally, the sub - vehicle 1 drives the clamping component 16 and the tower component to move to the placement position, and the clamping component 16 lowers the tower component to the support frame through the lifting component 15 and the clamping driving unit.

[0051] The S3 sub-vehicle moves from the mother vehicle to the Y track and transports the tower parts at the end of the Y track.

[0052] The RGV transport vehicle of the present invention realizes precise positioning and rapid movement through an automated control system. The high-speed operation of the mother vehicle on the X track and the flexible shuttling of the sub-vehicle on the Y track greatly shorten the transportation time of the tower parts, make the production process smoother, and can effectively meet the needs of large-scale and fast-paced production in the modern transmission line tower manufacturing industry. The production efficiency can be increased by more than 50%. At the same time, the RGV transport vehicle realizes automated operation and only requires a small number of technical personnel for equipment maintenance and monitoring, reducing the dependence on manual labor.
