Detailed implementation method
[0015] Embodiment 1
[0016] Such as Figures 1 to 3As shown in the figure, the utility model discloses a building material transfer vehicle. The technical solution adopted is as follows: it includes a vehicle board 1. At the left and right ends of the bottom of the vehicle board 1, wheel brackets 2 are respectively welded. At the front and rear ends of the bottom of the wheel brackets 2, wheels 3 are respectively rotatably installed. The diameter of the wheel 3 on the left wheel bracket 2 at the bottom of the vehicle board 1 is larger than that of the wheel 3 on the right wheel bracket 2 at the bottom of the vehicle board 1. This design helps the operator to lift and pull the transfer vehicle to a horizontal or vertical state. It also includes diagonal braces 8 and cross braces 9. There are two cross braces 9, which are symmetrically arranged front and rear under the vehicle board 1. At the left and right ends of the cross braces 9, diagonal braces 8 are respectively fixedly installed. The top ends of the diagonal braces 8 are respectively fixedly connected to the bottom of the vehicle board 1, and the bottom ends of the diagonal braces 8 are respectively fixedly connected to the middle parts of the wheel brackets 2. Through the arrangement of the diagonal braces 8 and the cross braces 9, it can be used to enhance the stability and load-bearing capacity of the transfer vehicle. A push handle 10 is fixedly installed in the groove provided in the middle of the right end of the vehicle board 1, which is convenient for the operator to push the transfer vehicle through the push handle 10. At the front and rear of the left end of the top of the vehicle board 1, L-shaped fixing plates 4 are symmetrically welded. A buffer unit 7 is arranged on the top of the L-shaped fixing plate 4. The buffer unit 7 includes a buffer bin 71, a second compression spring 72, a push plate 73, a buffer rod 74 and a buffer plate 75. There are two buffer bins 71, which are respectively arranged on the top of the L-shaped fixing plate 4. Inside the buffer bins 71, push plates 73 are respectively slidably installed. On the right sides of the push plates 73, second compression springs 72 are respectively fixedly installed. The other ends of the second compression springs 72 are respectively fixedly connected to the right sides inside the buffer bins 71. On the left sides of the push plates 73, buffer rods 74 are symmetrically arranged front and rear. The left ends of the buffer rods 74 respectively pass through the through holes provided on the left sides of the buffer bins 71 and are fixedly connected to the buffer plates 75 arranged in the front left of the L-shaped fixing plate 4. By lifting the wheel bracket 2 at the right end of the bottom of the vehicle board 1, the buffer unit 7 on the L-shaped fixing plate 4 at the left end of the vehicle board 1 is brought into contact with the ground, so that the transfer vehicle is in an upright state. When the buffer plate 75 contacts the ground, the impact force can be transferred to the second compression spring 72 through the buffer rod 74 and the push plate 73, so that the second compression spring 72 buffers the impact force. After the transfer vehicle is stable, next, the cast wooden templates to be transferred are moved one by one onto the L-shaped fixing plate 4. A fixing unit 5 is arranged in the middle of the vehicle board 1. The fixing unit 5 includes a fixing plate 51, a threaded rod 52, a guide groove 53, a sliding rod 54, a moving plate 55 and a handwheel 56. The guide groove 53 is arranged in the middle of the vehicle board 1. Inside the guide groove 53, a sliding rod 54 is arranged. The left and right ends of the sliding rod 54 are respectively fixedly connected to the inner sides of the guide groove 53. The sliding rod 54 is slidably connected with the sliding hole provided at the top of the convex block at the bottom of the moving plate 55 arranged at the right end of the top of the vehicle board 1. The fixing plate 51 is arranged at the lower left of the guide groove 53, and the fixing plate 51 is welded to the bottom left end of the vehicle board 1. In the middle of the right side of the fixing plate 51, a threaded rod 52 is rotatably installed. The threaded rod 52 is threadedly connected with the threaded hole provided on the convex block at the bottom of the moving plate 55. The right end of the threaded rod 52 is fixedly installed with a handwheel 56. By rotating the handwheel 56,The handwheel 56 drives the moving plate 55 to move along the guide groove 53 and the slide bar 54 in the guide groove 53 through the threaded rod 52, so that the moving plate 55 presses against the top of the cast wooden formwork, thereby realizing clamping and fixing. A clamping unit 6 is arranged on the top of the moving plate 55. The clamping unit 6 includes a clamping frame 61, a spring chamber 62, a baffle 63 and a first compression spring 64. There are two spring chambers 62, which are symmetrically arranged front and back on the top of the moving plate 55 respectively. The clamping frame 61 is slidably installed inside the spring chamber 62. The end parts of the clamping frame 61 are fixedly connected to the baffle 63 slidably installed inside the spring chamber 62. The first compression springs 64 are respectively arranged on the tops of the baffles 63, and the first compression springs 64 are respectively sleeved on the outside of the clamping frame 61. The upper and lower ends of the first compression spring 64 are fixedly connected to the inner top of the spring chamber 62 and the top of the baffle 63 respectively. By pulling out the clamping frame 61 outward, the baffle 63 at the end of the clamping frame 61 will squeeze the first compression spring 64, and then the other end of the clamping frame 61 can be abutted against the front of the outermost cast wooden formwork. Then, release the clamping frame 61. Under the action of the first compression spring 64, the clamping frame 61 can clamp and fix the cast wooden formwork.
[0017] The working principle of the present utility model: When in use, first, the transporter is pushed to the vicinity of the vertically placed cast wooden formwork, and then the wheel frame 2 at the right end of the bottom of the car body 1 is lifted, so that the buffer unit 7 on the L-shaped fixing plate 4 at the left end of the car body 1 contacts the ground, so that the transporter is in an upright state, that is, the loading and unloading state. When the buffer plate 75 in the buffer unit 7 contacts the ground, the impact force can be transferred to the second compression spring 72 through the buffer rod 74 and the push plate 73, so that the second compression spring 72 buffers the impact force. After the transporter is stable, next, the cast wooden formwork to be transported is moved to the L-shaped fixing plate 4 one by one. When fixing the cast wooden formwork, by rotating the handwheel 56, the handwheel 56 drives the moving plate 55 to slide downward along the guide groove 53 and the slide bar 54 in the guide groove 53 through the threaded rod 52. When the moving plate 55 approaches the cast wooden formwork, the operator can pull the clamping frame 61 outward, which will cause the baffle 63 at the end of the clamping frame 61 to squeeze the first compression spring 64, and then the other end of the clamping frame 61 can be abutted against the front of the outermost cast wooden formwork. Then, release the clamping frame 61. Under the action of the first compression spring 64, the clamping frame 61 can clamp the cast wooden formwork to achieve preliminary fixation. Then, continue to rotate the handwheel 56 to make the moving plate 55 press against the top of the cast wooden formwork, thereby realizing clamping and fixing. Finally, when the transporter is restored to the horizontal state, that is, the moving state, since the diameter of the wheel 3 on the left-end wheel frame 2 at the bottom of the car body 1 is larger than the diameter of the wheel 3 on the right-end wheel frame 2 at the bottom of the car body 1, this design helps the operator to restore the transporter to the horizontal state.
