Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, in particular to a conveying rack with the functions of changing the number of conveying layers and extending the length of the conveying layers. Background Art

[0002] Conveyor racks are a common type of conveying equipment, often used for conveying solid materials. With advancements in production, conveyor racks have evolved from the common single-layer model to include double-layer and even multi-layer models. However, the number of layers on existing conveyor racks is mostly fixed, making it impossible to adjust the number of layers. Furthermore, due to size limitations, the length of most conveyor racks is also fixed. Consequently, existing conveyor racks have certain limitations in practical use.

[0003] A search revealed Chinese patent application number 201120569572.3, which discloses a multi-layer, flip-up transport rack. The rack comprises a chassis frame, a rectangular hanger fixed to the chassis frame, and a plurality of rubber sheets fixedly mounted along the height of the rectangular hanger. The two ends of the rubber sheets are hung on either side of the rectangular frame via chains. Rectangular flat steel is fixed to the side walls of the rubber sheets, and hooks are fixed to the side walls of the rectangular hanger. The other ends are welded to a middle rectangular tube using a chain. Hooks are welded to corresponding positions on the crossbeam of the middle rectangular tube. When the top four layers are not in use, the hooks and chains cooperate to flip them up and hang them on the hooks, without affecting the placement and retrieval of products on the lower layers. The rack is economical and durable, prevents collisions between products, allows for multi-layered storage, and facilitates product placement and retrieval, fully utilizing the space in the transport vehicle. This patent utilizes a flip-up and folding method to adjust the number of transport layers, but suffers from the drawback of a fixed length. Summary of the Invention

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 5As shown, a conveyor frame with the function of changing the number of conveying layers and extending the length of the conveying layer includes a base frame body 1, a rotating conveyor frame body 2 rotatably mounted on the top of the base frame body 1, and two sets of conveyor plate modules distributed vertically are provided on the rotating conveyor frame body 2. In this embodiment, the present invention sets up two upper and lower conveyor layers, and in actual use, the number of conveyor plates can be increased or decreased according to the needs of use. The first conveyor plate module 3 located on the lower layer is horizontally fixedly connected to the rotating conveyor frame body 2, and the second conveyor plate modules 4 located on the upper layer are provided with two and are horizontally distributed left and right. After the two second conveyor plate modules 4 are horizontally combined, they are adapted to the length of the first conveyor plate module 3.

[0027] The two second conveyor plate modules 4 are slidably mounted on the rotating conveyor frame 2 in the vertical direction, and the movement tracks of the two second conveyor plate modules 4 are in an eight-shaped shape. Limited position fixing components are set at the top and bottom of the track to fix the second conveyor plate module 4 after each movement.

[0028] The base frame 1 is an I-shaped seat plate structure, and a rotation mounting hole 13 is provided at the middle position of the top of the base frame 1. The rotating conveying frame 2 is composed of a connecting frame seat 5, two side frame plates 6 that are symmetrically distributed front and back and fixedly connected to the two ends of the connecting frame seat 5, and four track plates 7 arranged on the left and right sides of the two side frame plates 6. A connecting rod 14 that cooperates with the rotation mounting hole 13 is provided in the middle of the bottom of the connecting frame seat 5. Through the rotation mounting hole 13 and the connecting rod 14, the rotating conveying frame 2 can be rotatably mounted on the base frame 1, thereby adjusting the conveying direction of the first conveying plate module 3 and the second conveying plate module 4. The two positioning holes 16 on the front and back sides of the top of the base frame 1 are provided with a rotation angle positioning component that cooperates with the two positioning holes 16 at the bottom of the two side frame plates 6 on the rotating conveying frame 2. After each rotation of the rotating conveying frame 2, the rotation angle positioning component cooperates with the positioning hole 16 to achieve the post-rotation positioning of the rotating conveying frame 2. The two track plates 7 on the same side frame plate 6 are distributed in an eight-shaped pattern, and the middle parts of the front and rear sides of the two second conveyor plate modules 4 are correspondingly slidably installed on the four track plates 7, and the limiting fixing components are arranged on the two track plates 7 on the front side.

[0029] As a further improvement to this embodiment, four guide slots 8 are provided on the four track plates 7, and four connecting guide blocks 9 are slidably provided in the four guide slots 8. The four connecting guide blocks 9 are all square block structures. The middle portions of the front and rear sides of the two second conveyor plate modules 4 are correspondingly fixedly connected to the inner side walls of the four connecting guide blocks 9, and a pulling handle 10 is provided on the outer side walls of the two connecting guide blocks 9 on the two front track plates 7. The length requirements of the guide slots 8 are required to ensure that: when the connecting guide blocks 9 move to the upper limit position of the guide slots 8, the two second conveyor plate modules 4 are flush with each other; when the connecting guide blocks 9 move to the lower limit position of the guide slots 8, the two second conveyor plate modules 4 are flush with the two ends of the first conveyor plate module 3. The pulling handle 10 facilitates the operator to pull the second conveyor plate module 4 to slide up and down along the guide slots 8.

[0030] As a further improvement to this embodiment, the position-limiting and fixing assembly includes two arc-shaped clips 11 rotatably mounted on the two front track plates 7 and located at the top and bottom of the guide slots 8. Locking nuts 12 are coaxially connected to the arc-shaped clips 11, and the clip portion dimensions of the arc-shaped clips 11 are adapted to the dimensions of the pull handle 10. The arc-shaped clips 11 support and position the pull handle 10, thereby limiting the movement of the second conveyor plate module 4. The locking nuts 12 can lock the rotated arc-shaped clips 11, limiting their rotation.

[0031] As a further improvement to this embodiment, the rotation angle positioning assembly includes two adjustment slots 17 provided at the bottom of the two side frame plates 6 and distributed in the left-right direction, two mounting seats 18 slidably mounted in the two adjustment slots 17, and two telescopic positioning rods 15 fixedly and vertically connected to the two mounting seats 18. The two telescopic positioning rods 15 are adapted to the size of the two positioning holes 16. The telescopic positioning rods 15 can move left and right at the bottom of the side frame plates 6 through the mounting seats 18. After the rotating conveying frame 2 rotates horizontally, the telescopic positioning rods 15 can be moved along the adjustment slots 17 to a position above the positioning hole 16 and then reinserted into the positioning hole 16.

[0032] The working principle and use process of the present invention:

[0033] like Figure 1The figure shows the double-layer conveying state of the conveyor frame of the present invention. When it is necessary to switch to a single-layer conveying state: first ensure that there is no object remaining on the second conveyor plate module 4, then loosen the locking nut 12 at the top of the guide chute 8, rotate the arc-shaped bracket 11 to release the restriction on the pulling handle 10, then the operator pulls the second conveyor plate module 4 downward to the lower limit position of the guide chute 8 by pulling the handle 10. At this time, the left and right second conveyor plate modules 4 are flush with the left and right ends of the first conveyor plate module 3, then rotate the arc-shaped bracket 11 at the bottom of the guide chute 8 to limit the pulling handle 10 and tighten the locking nut 12. When it is necessary to switch to a double-layer conveying state, the above process can be reversed. When the conveying direction of the conveying layer needs to be adjusted: first pull the telescopic positioning rod 15 out of the positioning hole 16, then rotate the rotating conveying frame 2. After rotating the rotating conveying frame 2, slide the telescopic positioning rod 15 so that the telescopic positioning rod 15 moves to the top of the positioning hole 16 and inserts it into the positioning hole 16, and then rotates and positions it.
