[0016] The following further details the specific embodiments of the utility model with reference to the accompanying drawings.
[0017] As Figures 1 to 6 can be seen, an electric flat car for tunnel handling with a scissor lift includes a vehicle body 1. Driving wheel sets are arranged at both the front and rear ends of the bottom of the vehicle body 1. A scissor lift 2 is arranged above the vehicle body 1. A tabletop 3 is arranged above the scissor lift 2. A plurality of U-shaped plates 4 are arranged above the tabletop 3. Items are placed on the U-shaped plates 4. The scissor lift 2 is a hydraulic scissor lift. The opening and closing of the scissor lift 2 realizes the lifting of the tabletop 3 so as to adjust the height of the items;
[0018] The drive wheel set includes a balance beam 5 rotatably arranged at the bottom of the vehicle body 1. A drive wheel 6 and an auxiliary wheel 7 are respectively arranged on both sides of the balance beam 5. The auxiliary wheel 7 is rotatably connected to the balance beam 5. The positions of the drive wheels 6 of the front and rear two drive wheel sets are on different sides of the vehicle body 1. The drive wheel 6 includes a connecting seat 8 fixedly connected to the balance beam 5. The drive wheel 6 is rotatably arranged at the bottom of the connecting seat 8. The drive wheel 6 is controlled by a drive motor 9. A steering motor 10 is arranged between the drive wheel 6 and the connecting seat 8. The drive motor 9 controls the rotation of the drive wheel 6, and the steering motor 10 controls the steering of the drive wheel 6.
[0019] When the present utility model is specifically used,
[0020] Place the article on the U-shaped plate 4. The groove on the U-shaped plate 4 can hold the article, so that the article will not fall during transportation. When transporting, lower the height of the tabletop 3 to reduce the collision volume and avoid collisions in the tunnel, which will affect the transportation. And the drive wheel set can realize the forward movement, backward movement, steering and in-situ rotation of the vehicle body 1, which is convenient for transporting the article and the construction after the transportation in place.
[0021] The movement of the vehicle body 1 is controlled by the drive wheel set. The drive wheel 6 rotates under the action of the drive motor 9 to realize the movement of the vehicle body 1. The steering motor 10 controls the steering of the drive wheel 6, driving the vehicle body 1 to realize left turn, right turn and in-situ rotation, so as to adjust the movement direction of the vehicle body 1 and the position of the article. The positions of the drive wheels 6 of the front and rear two drive wheel sets are on different sides of the vehicle body 1. When the two drive wheels 6 rotate in the same direction, they drive the vehicle body 1 to move in a certain direction. When the two drive wheels 6 rotate in opposite directions, a large rotation of the vehicle body 1 is realized. The orientation and rotation speed of the drive wheel 6 cooperate to complete the control of the movement of the vehicle body 1.
[0022] The drive wheel 6 and the auxiliary wheel 7 are connected to the bottom of the vehicle body 1 through the balance beam 5. When the road surface is uneven, they can rotate around the center of the balance beam 5 to keep the vehicle body 1 balanced. The auxiliary wheel 7 adopts a universal wheel, which can change with the change of the drive wheel 6 and cooperate with each other to complete the control of the movement of the vehicle body 1.
[0023] An electric control box is arranged in the vehicle body 1. The electric control box is electrically connected to the scissor lift 2, the drive motor 9 and the steering motor 10.
[0024] A fixing frame 11 is rotatably arranged below the connecting seat 8. The drive wheel 6 is rotatably arranged in the fixing frame 11. A first gear ring 12 is arranged outside the connecting seat 8. The steering motor 10 is fixed outside the fixing frame 11 and a first gear 13 meshing with the first gear ring 12 is arranged on the output shaft of the steering motor 10. A second gear ring 14 is arranged outside the drive wheel 6. A second gear 15 meshing with the second gear ring 14 is arranged on the output shaft of the drive motor 9.
[0025] When the vehicle body 1 needs to turn, the steering motor 10 drives the first gear 13 to rotate externally meshed with the first toothed ring 12, causing the fixing frame 11 to rotate relative to the connecting seat 8, and an angle is generated between the driving wheel 6 and the length direction of the vehicle body 1, thereby adjusting the traveling direction of the vehicle body 1. The drive circuit drives the second gear 15 to rotate, and the second toothed ring 14 rotating with the second gear 15 drives the driving wheel 6 to rotate, and the vehicle body 1 travels through the friction force with the ground.
[0026] Compared with the prior art, the utility model has the following beneficial effects: By arranging two sets of driving wheel sets and controlling the two driving wheels separately, the vehicle body can move forward, backward, turn left, turn right, travel obliquely and rotate in place, which is convenient for use in the complex environment in the tunnel; at the same time, the upper part of the vehicle body is connected to the table top through a scissor, and the height of the table top can be adjusted, so that the items to be carried can be more conveniently loaded and unloaded and directly serve as a workbench to lift the items to the construction position; a plurality of U-shaped plates are arranged on the table top, which can clamp tubular objects and make them more stable during the handling process to avoid falling.
