Description

Technical Field

[0001] The embodiments of the present invention relate to the field of transfer technology, specifically to a DC steering wheel type trackless remote-controlled transfer vehicle. Background Technology

[0002] Currently, my country's manufacturing market is developing towards automation and intelligence. While greatly reducing labor costs, it also promotes the standardization and unification of product quality, making product quality quite stable. However, the proportion of automated and intelligent production in the special vehicle sector is relatively low, which means it still cannot escape the category of labor-intensive industries.

[0003] During the production and processing of special vehicles, the transfer of vehicle frames within the workshop requires the use of overhead cranes for hoisting. The frames are then lifted onto a platform and transported using forklifts or overhead cranes. However, the number of overhead cranes in the workshop is limited. Forklifts, due to their structural design (limited for the length and width of the forks) and their counterweight, also have limited capacity, resulting in a limited number of frames that can be transferred at a time. This reduces transfer efficiency. Furthermore, due to the size and counterweight limitations of forklifts, their stability is also limited when transferring larger vehicle frames. Overhead cranes lift the vehicle frames to a certain height, and during transfer, the steel cables make directional control difficult, leading to lower stability. Collisions or falls with equipment or workpieces in the workshop could cause significant safety accidents. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a DC steering wheel type trackless remote control transfer vehicle, which solves the technical problems of low efficiency and stability in the frame transfer process in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a DC steering wheel type trackless remote-controlled transfer vehicle, including a vehicle body, and further comprising: A traveling mechanism, disposed below the vehicle body, is used to drive the vehicle body forward, backward, and turn. The traveling mechanism includes: A bogie is rotatably mounted on the car body, the rotation axis of the bogie is vertical, and a rotation angle sensor is provided on the car body for monitoring the rotation angle of the bogie. The wheel is rotatably mounted on the bogie, the wheel is in contact with the ground, and the wheel's axis of rotation is horizontally positioned. The support frame, which is vertically and vertically mounted on the vehicle body via a lifting mechanism, includes: A scissor lift carrier 1, the bottom of which is rotatably connected to the vehicle body, and the top of which is rotatably connected to the support frame; A drive unit is rotatably mounted on the vehicle body, and the output end of the drive unit is rotatably connected to the central axis of the scissor lift to drive the scissor lift to perform a scissor lift action; A rolling conveyor mechanism, disposed on the support frame, is used to transfer the vehicle frame and limit its movement during the transfer process. The rolling conveyor mechanism includes: The rollers are arranged in two rows, with the two rows of rollers located on both sides of the length direction of the support frame. The rollers are rotatably mounted on the support frame. The roller is conical and inclined toward the middle of the support frame to limit the centering of the frame; The clamping arm is rotatably mounted at the end of the support frame and is used to clamp the vehicle frame. There are two sets of clamping arms, which are located on both sides of the support frame in the width direction. Each set has two clamping arms, and the bottom of the clamping arm is rotatably connected to the support frame.

[0006] To further ensure the stability of the frame, a fall arrestor is also included. This fall arrestor is used to limit the lateral movement of the frame. The fall arrestor includes: A connecting plate, which is fixedly connected to the arm; A limiting plate is fixedly connected to the connecting plate via an elastic element, and the limiting plate is in contact with the vehicle frame.

[0007] To ensure vehicle stability, an anti-rollover component is also included. This component provides auxiliary lateral support to the vehicle body and includes: Diagonal bracing, which is movably mounted on both sides of the vehicle body; A roller is rotatably mounted below the diagonal brace and is in contact with the ground.

[0008] Preferably, the diagonal brace is mounted on the vehicle body via a second scissor lift, and the side of the second scissor lift closest to the vehicle body is rotatably connected to the first scissor lift to perform a scissor lift action along with the first scissor lift.

[0009] The beneficial effects of the embodiments of the present invention are as follows: 1. In this invention, the vehicle body can move forward and backward by rotating the wheels. The rotation angle of the bogie can be monitored by the rotation angle sensor, thereby accurately controlling the turning angle of the vehicle body. The vehicle body to be transferred is placed on the carrier frame, which can realize the transfer of the vehicle body. The size of the carrier frame is much larger than that of a forklift, so the number of vehicle bodies that can be transported at one time is more than that of a forklift. In addition, the transfer vehicle is more flexible and does not rely on rails. Multiple units can be set up in the workshop, without being restricted by the site. The conveying efficiency is higher than that of the smaller forklifts and the large-area overhead cranes in the prior art.

[0010] 2. In this invention, the scissor lift action of the scissor lift can drive the support frame to rise and fall, thereby adjusting the height of the frame. At the same time, the rotation of the roller can drive the frame to move on the support frame, which facilitates the support frame to receive and place the frame, and reduces the lifting and placement work before and after the transfer to a certain extent.

[0011] 3. In this invention, the clamping arms on both sides of the carrier can clamp or block the frame. When the clamping arms rotate inward, they can drive the limiting plate to clamp and limit the frame, ensuring the stability of the frame on the carrier and blocking the side of the frame to prevent it from falling. During transportation, the scissor lift one is in a retracted state, so that the carrier and the frame are in a lower position, lowering the center of gravity during the transfer, thereby preventing the vehicle from tilting or even tipping over. When the scissor lift one drives the carrier and the frame to rise, the scissor lift two extends with the scissor lift one, driving the diagonal support frame away from the vehicle body. The diagonal support frame provides auxiliary support to the side of the vehicle body, preventing the vehicle body from tilting or even tipping over after it is raised. Attached Figure Description

[0019] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 7 As shown, it illustrates a DC steering wheel type trackless remote control transfer vehicle according to an embodiment of the present invention, including a vehicle body 1, a walking mechanism, a support frame 2, a rolling conveyor mechanism, and a grab arm 3.

[0021] like Figures 1 to 3As shown, the traveling mechanism is located below the vehicle body 1 and is used to drive the vehicle body 1 forward, backward, and turn. The traveling mechanism includes a bogie 101 and wheels 102. The bogie 101 is rotatably mounted on the vehicle body 1, and the rotation axis of the bogie 101 is vertical. A fixed shaft 103 is fixedly mounted on the vehicle body 1, and the bogie 101 is rotatably mounted on the fixed shaft 103. A motor 104 and a motor 105 are mounted on the bogie 101. A drive gear 106 is fixedly connected to the output end of the motor 104. A fixed gear 107 is fixedly fitted on the outside of the fixed shaft 103. The drive gear 106 and the fixed gear 107 mesh. A rotation angle sensor 108 is provided on the vehicle body 1 to monitor the rotation angle of the bogie 101. A driven shaft 109 is rotatably mounted on the bogie 101, and the rotation angle sensor 108 is mounted on the driven shaft 109. A driven gear 110 is coaxially fixedly connected to the driven shaft 109. 110 meshes with fixed gear 107, and wheel 102 is rotatably mounted on bogie 101. Wheel 102 is fixedly mounted on the output end of motor 2 105. Wheel 102 is in contact with the ground, and the rotation axis of wheel 102 is horizontally set. Motor 104 can drive drive gear 106 to rotate. Under the action of fixed gear 107, drive gear 106 rotates around fixed shaft 103, thereby adjusting the angle of bogie 101. When bogie 101 rotates, it drives driven shaft 109 and driven gear 110 to rotate around fixed shaft 103. Rotation angle sensor 108 monitors the rotation angle of bogie 101, forming a closed loop for adjusting the rotation angle of bogie 101 with motor 104. The vehicle body 1 is equipped with a battery for powering motor 104 and motor 2 105 and a receiver for receiving remote control signals from a remote controller. The forward, backward and turning movements of vehicle body 1 can be controlled by the remote controller.

[0022] like Figures 1 to 7 As shown, the support frame 2 can be raised and lowered on the vehicle body 1 via a lifting mechanism. The lifting mechanism includes a scissor lift 201 and a drive unit 202. The bottom of the scissor lift 201 is rotatably connected to the vehicle body 1, and the top of the scissor lift 201 is rotatably connected to the support frame 2. The drive unit 202 is rotatably mounted on the vehicle body 1, and the output end of the drive unit 202 is rotatably connected to the central axis of the scissor lift 201 to drive the scissor lift 201 to perform a scissor lift action. The drive unit 202 can be a hydraulic cylinder or an electric cylinder. The vehicle body can be equipped with a hydraulic oil tank and hydraulic pump adapted to the hydraulic cylinder. The hydraulic cylinder pushes the scissor lift 201 to perform a scissor lift action, thereby driving the support frame 2 to rise and fall. The vehicle body is placed on the support frame 2, thereby adjusting the height of the vehicle body to correspond to the height position of the transfer, which is convenient for receiving the vehicle body or transporting the vehicle body to a suitable position.

[0023] like Figures 1 to 4As shown, a rolling conveyor mechanism is installed on the support frame 2 to transfer the vehicle frame and limit its movement during the transfer process. The rolling conveyor mechanism includes two rows of rolling wheels 301, which are located on both sides of the length of the support frame 2. The rolling wheels 301 are rotatably mounted on the support frame 2 and are tapered and inclined towards the center of the support frame 2 to limit the vehicle frame inward. A motor 302 is installed on the support frame 2. Both the rolling wheels 301 and the motor 302 are coaxially fixedly connected to sprockets 303. Adjacent sprockets 303 are connected by chain drive. The motor 302 can drive multiple rolling wheels 301 to rotate. The vehicle frame is placed on top of the rolling wheels 301. The rotation of the rolling wheels 301 can adjust the position of the vehicle frame and move the vehicle frame from the support frame 2 to the conveying position.

[0024] like Figures 1 to 5 As shown, the clamping arms 3 are rotatably mounted at the end of the support frame 2 for clamping the frame. There are two sets of clamping arms 3, located on both sides of the support frame 2 in the width direction. Each set has two clamping arms 3. The bottom of the clamping arms 3 is rotatably connected to the support frame 2. Two hydraulic cylinders or electric cylinders are rotatably mounted on both sides of the support frame 2 in the width direction. The bottom of the clamping arms 3 is rotatably connected to the output end of the hydraulic cylinders or electric cylinders. By extending, retracting, and rotating the hydraulic cylinders or electric cylinders, the two clamping arms 3 can be driven to open and close. The relative rotation of the two clamping arms 3 can clamp the side of the frame or block the end of the frame to ensure the stability of the frame and prevent the frame from falling off the support frame 2. When the frame needs to be transported, the two clamping arms 3 are moved away from the frame to avoid obstructing it. At the same time, during the transportation process, the frame can be moved while providing a certain degree of protection to the side of the frame to prevent the frame from falling.

[0025] like Figures 1 to 5 As shown, to further ensure the stability of the frame, an anti-fall component is also included. The anti-fall component is used to limit the side movement of the frame. The anti-fall component includes a connecting plate 401 and a limiting plate 402. The connecting plate 401 is fixedly connected to the arm 3. The limiting plate 402 is fixedly connected to the connecting plate 401 through an elastic element 403. The limiting plate 402 is in contact with the frame. When the arm 3 rotates inward to tighten the frame, it drives the connecting plate 401 and the limiting plate 402 to move closer to the frame. The elastic element 403 can be a spring, elastic steel, rubber block or airbag. The elastic element 403 drives the limiting plate 402 to press against the surface of the frame, further limiting the frame. The elasticity of the elastic element 403 can adapt to the surface undulations of the frame, so that the limiting plate 402 and the frame are close together, ensuring the limiting effect on the frame. The connecting plate 401 provides the final line of defense to prevent the frame from detaching from the support frame 2, thereby preventing the frame from falling.

[0026] like Figures 1 to 7As shown, to ensure the stability of the vehicle body 1, an anti-tipping component is also included. This component provides auxiliary support to the sides of the vehicle body 1. The anti-tipping component includes a diagonal brace 501 and rollers 502. The diagonal brace 501 is movably mounted on both sides of the vehicle body 1. The rollers 502 are rotatably mounted below the diagonal brace 501 and are in contact with the ground. The rotation of the rollers 502 allows the diagonal brace 501 to move. The diagonal brace 501 is mounted on the vehicle body 1 via a second scissor lift 503. The side of the second scissor lift 503 closest to the vehicle body 1 is rotatably connected to the first scissor lift 201 to perform a scissor lift action. Simultaneously with the drive unit 202 driving the first scissor lift 201 to perform the scissor lift action, the diagonal brace 501 is moved by the first scissor lift 201. The ends of the scissor lift 203 and scissor lift 201 are rotatably connected. Scissor lift 201 can drive scissor lift 203 to perform scissor lift actions synchronously. That is, while scissor lift 201 drives the support frame 2 to rise, scissor lift 203 drives the diagonal support frame 501 away from the vehicle body 1. As the height of the support frame 2 increases, that is, as the center of gravity of the DC steering wheel type trackless remote control transfer vehicle rises, the contact range between the vehicle body 1 and the ground through the diagonal support frame 501 also increases. As the diagonal support frame 501 moves away from the vehicle body 1, the stability of the vehicle body 1 is improved, thereby ensuring the stability of the vehicle body 1 after the support frame 2 drives the frame to rise, avoiding the vehicle body 1 from tilting or falling over due to the increase in the center of gravity, and improving the stability of the transfer.

[0027] The working principle or usage process of this DC steering wheel type trackless remote-controlled transfer vehicle is as follows: The drive unit 202 can be used to raise the support frame 2 to the position of receiving the vehicle frame. At the same time as the support frame 2 is raised, the scissor lift 2 503 drives the diagonal support frame 501 away from the vehicle body 1 to provide auxiliary support to the side of the vehicle body 1. The vehicle frame to be transferred is hoisted or pushed above the roller 301 of the support frame 2 by the overhead crane or other equipment. After the vehicle frame is loaded, the hydraulic cylinder drives the clamping arm 3 to clamp the vehicle frame. At the same time, the clamping arm 3 drives the limiting plate 402 to clamp and limit the side of the vehicle frame. The drive unit 202 drives the scissor lift 1 201 to descend, and at the same time, the diagonal support frame 501 moves closer to the vehicle body 1. The operation of motor 104 and motor 105 is controlled by remote control, and the vehicle body 1 moves forward, backward or turns according to the ground markings. The vehicle frame is moved within or between workshops. After being moved to the appropriate position, the drive unit 202 drives the support frame 2 to rise to the receiving position. During this process, the scissor lift 201 drives the diagonal support frame 501 away from the vehicle body 1 to support the vehicle body 1. The hydraulic cylinder drives the arm 3 away from the frame, and the motor 302 drives the roller 301 to rotate, rolling the frame above it down from the support frame 2 to the receiving position, such as the placement platform, or the frame can be lifted onto the placement platform by an overhead crane or other equipment to complete the transfer process.
