Description

Technical Field

[0001] This utility model relates to a material turnover vehicle, and more specifically, to a gravity turnover vehicle. Background Technology

[0002] When manufacturing products, companies transfer different components to the corresponding assembly lines. Workers then take materials from the turnover carts and assemble them with the products on the assembly line. Most of these materials are stacked on the turnover carts. Initially, the materials are stacked high, and workers need to reach up to pick them up. As they are picked up, the amount of materials on the turnover carts gradually decreases, and the height also decreases. At this point, workers need to bend over to pick up the materials, which is labor-intensive. Therefore, there is an urgent need to improve this process. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a gravity turnover cart. After the material is placed on the lifting frame, the lifting frame will be lowered by the tension spring, reducing the height. After the material is reduced, the tension spring will retract, and the lifting frame will rise, reducing the labor intensity of the workers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a gravity turnover cart, comprising a trolley and a lifting frame located inside the trolley, wherein the trolley and the lifting frame are connected by tension springs, the trolley comprising a first bottom frame and a first side frame connected to the first bottom frame, universal wheels fixed at the four corners of the lower part of the first bottom frame, crossbeams provided on both sides of the first side frame, the lifting frame located inside the first side frame, and the tension springs respectively located on the outer sides of the four corners of the lifting frame, wherein the upper end of the tension spring is connected to the crossbeam and the lower end is connected to the lifting frame.

[0005] Furthermore, a guide rod is provided inside the first side frame. The guide rod is located on both sides of the lifting frame. The upper end of the guide rod is connected to the crossbeam and the lower end is connected to the first bottom frame. Slider blocks are fixed on both sides of the lifting frame, and the guide rod passes through the sliders.

[0006] Furthermore, the lifting frame includes a second bottom frame and a second side frame connected to the second bottom frame, the tension spring is connected to the bottom of the second side frame, and the slider is fixed to the outside of the second side frame.

[0007] Furthermore, the first side frame is fixed with a first side plate on both sides of the tension spring, the second bottom frame is fixed with a bottom plate on the upper part, and the second side frame is fixed with a second side plate on the outside.

[0008] Furthermore, the second bottom frame includes a first crossbar and a second crossbar, and the second side frame includes a vertical bar. The ends of the first crossbar, the second crossbar, and the vertical bar are connected by connectors.

[0009] Furthermore, the connecting member includes a first clamping plate, a second clamping plate, a third clamping plate, and a fourth clamping plate. The vertical bar and the second horizontal bar are connected through the first clamping plate and the second clamping plate, and the first horizontal bar and the second horizontal bar are connected through the third clamping plate and the fourth clamping plate.

[0010] Furthermore, the lower end of the vertical rod is inserted between the first clamping plate and the second clamping plate, which are fixed by bolts to clamp the lower end of the vertical rod. The end of the first horizontal rod is inserted between the third clamping plate and the fourth clamping plate, which are fixed by bolts to clamp the end of the first horizontal rod.

[0011] Furthermore, the second crossbar is provided with multiple limiting grooves on its periphery. The width of the bottom of the limiting groove is smaller than the width of the opening of the limiting groove. The first clamping plate is provided with a first protrusion at its lower part, the second clamping plate is provided with a second protrusion at its lower part, the third clamping plate is provided with a third protrusion on its side, and the fourth clamping plate is provided with a fourth protrusion on its side. The first protrusion is inserted into a limiting groove, the side of the second protrusion abuts against the side of the third protrusion, the second protrusion and the third protrusion are inserted together into a limiting groove adjacent to the first protrusion for limiting, and the fourth protrusion is inserted into a limiting groove adjacent to the third protrusion for limiting.

[0012] In summary, this utility model has the following beneficial effects:

[0013] When materials are stacked inside the lifting frame, the heavier the lifting frame, the greater the stretch of the tension spring. As the materials are stacked higher, the lifting frame will descend, thus preventing the upper layer of materials from being too high. Workers do not need to lift their hands to pick up the materials. During the process of workers picking up materials, as the amount of materials decreases, the gravity on the lifting frame decreases. At this time, the tension spring will contract and drive the lifting frame to rise, thus preventing the lower layer of materials from being too low and greatly reducing the labor intensity of workers when picking up materials.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this embodiment discloses a gravity-operated turnover vehicle, including a trolley 1 and a lifting frame 2 located inside the trolley 1. The trolley 1 and the lifting frame 2 are connected by a tension spring 3. The trolley 1 includes a first bottom frame 11 and a first side frame 12 connected to the first bottom frame 11. Universal wheels 16 are fixed at the four corners of the lower part of the first bottom frame 11. Crossbeams 13 are provided on both sides of the first side frame 12. First side plates 15 are fixed on both sides of the first side frame 12 located on the tension springs 3. The lifting frame 2 is located inside the first side frame 12. The tension springs 3 are respectively located on the outer sides of the four corners of the lifting frame 2. The upper end of the tension spring 3 is connected to the crossbeam 13 and the lower end is connected to the lifting frame 2.

[0021] like Figure 1 As shown, when materials are stacked inside the lifting frame 2, the heavier the lifting frame 2, the greater the stretch of the tension spring 3. As the materials are stacked higher, the lifting frame 2 will descend, thus preventing the upper layer of materials from being too high. Workers do not need to lift their hands to pick up the materials. During the process of picking up materials, as the amount of materials decreases, the gravity on the lifting frame 2 decreases. At this time, the tension spring 3 will contract and drive the lifting frame 2 to rise, thus preventing the lower layer of materials from being too low and greatly reducing the labor intensity of workers when picking up materials.

[0022] The first side frame 12 is provided with guide rods 14, which are located on both sides of the lifting frame 2. The upper end of the guide rod 14 is connected to the crossbeam 13 and the lower end is connected to the first bottom frame 11. Slider blocks 23 are fixed on both sides of the lifting frame 2, and the guide rods 14 pass through the sliders 23. The lifting frame 2 includes a second bottom frame 21 and a second side frame 22 connected to the second bottom frame 21. A bottom plate 24 is fixed on the upper part of the second bottom frame 21, and a second side plate 25 is fixed on the outside of the second side frame 22. The tension spring 3 is connected to the bottom of the second side frame 22, and the sliders 23 are fixed on the outside of the second side frame 22. There are four guide rods 14 located on both sides of the second side frame 22. Through the cooperation of the guide rods 14 and the sliders 23, the lifting frame 2 can be lifted and guided, improving its stability.

[0023] like Figure 3 and Figure 4 As shown, the second bottom frame 21 includes a first horizontal bar 211 and a second horizontal bar 212, and the second side frame 22 includes a vertical bar 221. The ends of the first horizontal bar 211, the second horizontal bar 212, and the vertical bar 221 are connected by connectors. Specifically, the connectors include a first clamping plate 4, a second clamping plate 5, a third clamping plate 6, and a fourth clamping plate 7. The vertical bar 221 and the second horizontal bar 212 are connected by the first clamping plate 4 and the second clamping plate 5, and the first horizontal bar 211 and the second horizontal bar 212 are connected by the third clamping plate 6 and the fourth clamping plate 7. The lower end of the vertical bar 221 is inserted between the first clamping plate 4 and the second clamping plate 5. The first clamping plate 4 and the second clamping plate 5 are fixed by bolts 8 to clamp the lower end of the vertical bar 221. The end of the first horizontal bar 211 is inserted between the third clamping plate 6 and the fourth clamping plate 7. The three-ply plate 6 and the fourth-ply plate 7 are fixed by bolts 8 to clamp the end of the first crossbar 211. The second crossbar 212 has multiple limiting grooves 213 around its periphery. The width of the bottom of the limiting groove 213 is smaller than the width of the opening of the limiting groove 213. The first clamping plate 4 has a first protrusion 41 at its lower part, the second clamping plate 5 has a second protrusion 51 at its lower part, the third clamping plate 6 has a third protrusion 61 on its side, and the fourth clamping plate 7 has a fourth protrusion 71 on its side. The first protrusion 41 is inserted into a limiting groove 213, the side of the second protrusion 51 abuts against the side of the third protrusion 61, and the second protrusion 51 and the third protrusion 61 are inserted together into a limiting groove 213 adjacent to the first protrusion 41 for limiting. The fourth protrusion 71 is inserted into a limiting groove 213 adjacent to the third protrusion 61 for limiting.

[0024] Since the width of the bottom of the limiting groove 213 is smaller than the width of the opening of the limiting groove 213, the limiting groove 213 is a groove with barbs. When the second protrusion 51 and the third protrusion 61 abut against each other and are located in the limiting groove 213, the second clamping plate 5 and the third clamping plate 6 can only move horizontally along the limiting groove 213 and will not be pulled out of the limiting groove 213. When the first clamping plate 4 and the second clamping plate 5 are locked, and the third clamping plate 6 and the fourth clamping plate 7 are locked, the first clamping plate 4 and the second clamping plate 5 can clamp the second crossbar 212. At the same time, the third clamping plate 6 and the fourth clamping plate 7 can also clamp the second crossbar 212, thereby realizing the connection and fixation of the second bottom frame 21 and the second side frame 22, with good connection reliability.

All technical solutions falling within the scope of this utility model's concept are protected.
