Description

Technical Field

[0001] The present invention belongs to the technical field of material platforms, and particularly relates to a loading platform. Background Art

[0002] In actual production, inclined platforms are widely used. Their main functions are storage and transportation. Among material platforms, inclined platforms are the most widely used. They mainly utilize the rolling or sliding of materials on the inclined platform to achieve the feeding or receiving operations of materials.

[0003] Currently, the inclination of most material platforms is fixed. Affected by factors such as the size, material, surface shape, smoothness of the billet, and the bending degree of the billet itself, they often cannot fully meet the requirements of the speed and stability of billet transportation by inclination. That is, if the inclination of the material platform is too small or too large, there will be phenomena such as material jamming or excessive impact on downstream equipment due to too fast material speed. This not only increases the maintenance and operation time but also poses potential hazards to operators and downstream equipment. Moreover, the application of material platforms with a fixed inclination is relatively single and usually can only meet the transportation operations of some specific-shaped or -material materials, with relatively poor adaptability.

[0004] It can be seen that the material platforms in the prior art have problems such as poor adaptability in use, poor transportation stability, and high potential safety hazards. Therefore, it is of great significance to improve the adaptability in use and transportation stability of the material platform and reduce potential safety hazards. Summary of the Invention

[0061] To make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other arbitrarily without conflict.

[0062] like Figures 1 to 11 An embodiment of the present invention is shown, in which a loading platform is disclosed, including a table top 1 for storing and conveying materials, a front column 2 and a plurality of rear columns 3 are arranged below the table top 1, the front column 2 is arranged below the discharge end of the table top 1, and the plurality of rear columns 3 are respectively located behind the front column 2, and the front column 2 and the plurality of rear columns 3 are arranged and distributed together along the length direction of the table top 1.

[0063] In one embodiment, Figure 1 , Figure 2 , Figure 3As shown in the figure, a hinge portion 4 is provided at the top of the front column 2. The tabletop 1 is hinged to the hinge portion 4, and the tabletop 1 can rotate in the vertical direction. At the same time, an adjusting portion 5 is provided at the top of each rear column 3. The plurality of adjusting portions 5 are used to support the tabletop 1, and the adjusting portion 5 can lift the tabletop 1 so that the slope of the tabletop 1 can be adjusted.

[0064] In the loading table frame of this embodiment, by providing the tabletop 1 with an adjustable slope, the table frame can adapt to the feeding requirements of materials with different shapes, weights, and materials, thereby improving the adaptability of the table frame. At the same time, the staff can adjust the slope of the tabletop 1 to adjust the speed of the material moving to the external baffle member, so as to reduce the risk of excessive impact of the material on the external baffle member, which can not only reduce potential safety hazards but also save unnecessary maintenance and other operations. Moreover, the slope of the tabletop 1 can be adjusted, enabling the staff to adjust the tabletop 1 to an appropriate slope according to factors such as the material and shape of the material, so that the material can smoothly roll or slide on the tabletop 1, reducing the risk of material blockage, thereby improving the conveying stability of the material and further improving production efficiency.

[0065] In one embodiment, as Figure 2 , Figure 3 , Figure 4 shown, the hinge portion 4 includes a support seat 41 fixedly connected to the top of the front column 2. A support inclined surface 42 is integrally formed on the top of the support seat 41, and the inclination direction of the support inclined surface 42 is opposite to the inclination direction of the tabletop 1.

[0066] In one embodiment, as Figure 2 , Figure 3 , Figure 4 shown, two support plates 43 are fixedly connected to the support inclined surface 42. An articulated seat 44 is provided on the support inclined surface 42 between the two support plates 43. An articulated block 45 is fixedly connected to the bottom of the tabletop 1. An articulated shaft 46 is fixedly connected to the articulated seat 44. The articulated shaft 46 passes through the articulated block 45, and the articulated block 45 is rotatably sleeved on the articulated shaft 46 so that the tabletop 1 can swing around the articulated shaft 46.

[0067] In one embodiment, as Figure 2 , Figure 3 , Figure 4 shown, the articulated seat 44 is movably connected to the support inclined surface 42, and the articulated seat 44 can slide along the inclination direction of the support inclined surface 42. At the same time, a locking member 6 capable of fixing the articulated seat 44 is provided on the support seat 41.

[0068] If the position of the hinge shaft 46 is fixed to the rod, when the tabletop 1 is lifted by the adjustment part, when the tabletop 1 rotates around the hinge shaft 46, the position of the discharge end of the tabletop 1 will change, that is, the position of the key point of feeding at the end of the tabletop 1 will change. By providing a hinge seat 44 whose position can be adjusted, the position of the hinge shaft 46 can be adjusted, so that during the rotation of the tabletop 1, the position of the key point of feeding at the end of the tabletop 1 remains unchanged, that is, the slope of the tabletop 1 changes, but the position of the receiving material of the downstream equipment remains unchanged, thereby improving the feeding accuracy.

[0069] In one embodiment, as Figure 2 、 Figure 3 、 Figure 4 shown, the locking member 6 includes two strip-shaped holes 61 respectively formed in the support base 41, and the length direction of the strip-shaped holes 61 is arranged along the inclination direction of the support inclined surface 42. The hinge seat 44 and the support base 41 are connected by a plurality of pairs of fastening bolts 62, and the screw rod of the fastening bolt 62 can pass through the corresponding strip-shaped hole 61 to fix the hinge seat 44.

[0070] In one embodiment, as Figure 2 、 Figure 3 、 Figure 4 shown, adjusting screws 7 are respectively threadedly connected to the two support plates 43, and the adjusting screws 7 can abut against the side wall of the hinge seat 44 to limit the sliding of the hinge seat 44 along the inclination direction of the support inclined surface 42. At the same time, at least one adjusting gasket 8 is movably inserted between the support plate 43 at the low point of the support inclined surface 42 and the hinge seat 44. By increasing the number of adjusting gaskets 8, the position adjustment of the hinge seat 44 can be realized.

[0071] When the position of the hinge seat 44 needs to be adjusted, loosen the nut of the fastening bolt 62, then pull the hinge seat 44 to move and make the hinge shaft 46 located at the required position. At this time, insert the adjusting gasket 8 between the support plate 43 and the hinge seat 44. If multiple adjusting gaskets 8 need to be inserted, stack the multiple adjusting gaskets 8 and insert them between the support plate 43 and the hinge seat 44 to position the hinge seat 44. At the same time, rotate the adjusting screw 7 and make the adjusting screw 7 abut against the side wall of the hinge seat 44 to fix the position of the hinge seat 44. Subsequently, tighten the nut of the fastening bolt 62 to fix the hinge seat 44.

[0072] In one embodiment, as Figure 1 、 Figure 4 、 Figure 5 shown, the adjustment part 5 includes a first track slide plate 51 and a second track slide plate 52. The first track slide plate 51 is fixed to the top of the rear column 3, and the second track slide plate 52 is movably arranged on the top of the rear column 3, and the second track slide plate 52 can slide towards the first track slide plate 51.

[0073] In one embodiment, as Figure 4 , Figure 5 shown, a support portion 53 is provided between the first track slide plate 51 and the second track slide plate 52. Both ends of the support portion 53 form a vertical sliding fit with the first track slide plate 51 and the second track slide plate 52 respectively, and the support portion 53 is used to support the tabletop 1.

[0074] In one embodiment, as Figure 4 , Figure 5 shown, a limiting member 9 is provided on the rear column 3. The limiting member 9 is used to fix the second track slide plate 52 and enable the first track slide plate 51 and the second track slide plate 52 to jointly clamp the support portion 53, so as to realize the position limitation of the support portion 53.

[0075] In one embodiment, as Figure 6 , Figure 7 , Figure 8 , Figure 9 shown, the support portion 53 includes a slider 531. Both ends of the slider 531 form a vertical sliding fit with the first track slide plate 51 and the second track slide plate 52 respectively. A sliding sleeve 532 is sleeved on the slider 531. A supporting plate 533 is fixedly connected to the outside of the sliding sleeve 532, and the supporting plate 533 can abut against the lower surface of the tabletop 1.

[0076] In one embodiment, as Figure 7 , Figure 8 , Figure 9 shown, the middle position of the slider 531 is a cylindrical or arc-shaped cylindrical surface structure. In this embodiment, the middle position of the slider 531 is cylindrical. At the same time, the inner wall of the sliding sleeve 532 is rectangular, and the sliding sleeve 532 can rotate on the slider 531. At the same time, the width of the sliding sleeve 532 is smaller than the length of the slider 531, so that the slider 531 can slide along the axis direction of the slider 531, that is, the sliding sleeve 532 can translate. The length direction of the inner wall of the sliding sleeve 532 is greater than the outer diameter of the slider 531, so that the sliding sleeve 532 can slide on the slider 531, and the sliding direction of the sliding sleeve 532 is perpendicular to the axis direction of the slider 531.

[0077] When the slider 531 moves vertically and jacks up the tabletop 1, the inclination angle of the lower surface of the tabletop 1 also changes accordingly. At this time, by setting the sliding sleeve 532 that can rotate, translate and slide, the angle and position of the supporting plate 533 can be adjusted, so that the supporting plate 43 can closely adhere to the lower surface of the tabletop 1, thereby improving the supporting stability of the tabletop 1.

[0078] In one embodiment, as Figure 5 , Figure 6As shown, the limiting member 9 includes a limiting plate 91 vertically and fixedly connected to the top of the rear column 3, and the second track slide plate 52 is located between the limiting plate 91 and the first track slide plate 51. At least one limiting gasket 92 is movably inserted between the limiting plate 91 and the second track slide plate 52, and the limiting plate 91 and the second track slide plate 52 are connected by a plurality of limiting bolts 93.

[0079] In one embodiment, as Figure 6 , Figure 7 shown, the first track slide plate 51 and the second track slide plate 52 are arranged in an inclined shape with the bottoms approaching each other and the tops moving away from each other. Limiting inclined surfaces 10 are integrally formed at both ends of the slider 531, and the two limiting inclined surfaces 10 respectively fit with the first track slide plate 51 and the second track slide plate 52.

[0080] By increasing the number of limiting gaskets 92, the adjustment of the distance between the second track slide plate 52 and the first track slide plate 51 is realized, so that the slider 531 can move vertically, and then the adjustment of the height of the slider 531 is realized. At the same time, the bottoms of the first track slide plate 51 and the second track slide plate 52 approach each other, which can automatically realize the position limitation of the slider 531 in the vertically downward direction, thereby realizing the locking stability of the slider 531.

[0081] In one embodiment, as Figure 1 , Figure 10 , Figure 11 shown, at least one rear column 3 and the table top 1 are provided with a locking tie rod 11. The locking tie rod 11 includes a support ring 111 fixedly connected to the bottom of the table top 1, and a locking screw rod 112 is vertically and fixedly connected to the bottom of the support ring 111. A receiving ring 113 is fixedly connected to the top of the rear column 3, a locking hole 115 is formed in the receiving ring 113, the bottom end of the locking screw rod 112 passes through the locking hole 115 and is threadedly connected with a locking nut 114. By rotating the locking nut 114, the distance between the support ring 111 and the receiving ring 113 can be adjusted, so as to realize the position limitation of the table top 1 in the vertical direction, reduce the risk of vibration caused by the gaps of the structural members, and further ensure the stability of the table top 1.

[0082] In other embodiments, the support ring 111 and the receiving ring 113 can also be replaced by a chain or a steel cable. The main function is to adjust the slope of the table top 1 and then tighten the chain or the steel cable through the locking nut 114, so as to realize the position limitation of the table top 1 in the vertical direction. Therefore, other replaceable structures are acceptable. Of course, only the state where one column has the locking tie rod 11 is shown in this embodiment. In other embodiments, each column can also be provided with a locking tie rod 11, which can be selected according to the actual situation.

[0083] As can be seen from the above, the use of this device enables the slope of the tabletop 1 to be adjusted, so that the material table frame can adapt to the feeding requirements of materials with different shapes, weights and materials, thereby improving the adaptability of the material table frame. At the same time, multiple groups of material table frames can also be combined for use to adapt to the feeding operations of materials with larger lengths and widths.

[0084] At the same time, the staff can adjust the slope of the tabletop 1 to adjust the speed of the material moving to the external baffle component, so as to reduce the risk of excessive impact of the material on the external baffle component, which can not only reduce potential safety hazards, but also save unnecessary maintenance and other operations. At the same time, this design enables the material to move at a certain speed and stability as much as possible, thus ensuring the production rhythm.

[0085] Moreover, the slope of the tabletop 1 can be adjusted, enabling the staff to adjust the tabletop 1 to an appropriate slope according to factors such as the material and shape of the material, so that the material can roll or slide smoothly on the tabletop 1, reducing the risk of material blockage, thereby improving the conveying stability of the material and further enhancing the production efficiency.
