Description

TECHNICAL FIELD

[0001] The present application relates to the field of angle steel storage, and in particular to a material lifting device. BACKGROUND

[0002] Angle steel is an important component for manufacturing iron towers. Since the volume and weight of angle steel are relatively large, the current angle steel manufacturing enterprises generally use the telescopic shelves disclosed in the patent announcement document CN216316377U to store angle steel. However, there is a problem when storing angle steel using such telescopic shelves, i.e., the angle steel is placed on both sides of the stand column. Therefore, when the weight difference of the angle steel on both sides of the stand column is large, the telescopic shelf may collapse. SUMMARY

[0003] The present application proposes a material lifting device to solve the above problems.

[0004] The technical scheme adopted by the present application is as follows:

[0005] A material lifting device includes a base table, a stand column, a moving table, a lead screw mechanism, and a carrier frame. The base table is not less than two, and is fixedly arranged on the ground without contact between the base tables. Each base table is provided with multiple stand columns in parallel and without contact, and the adjacent two stand columns on the same base table form a clamping channel. The two ends of the carrier frame are slidably connected together in the clamping channel. The base table is used to directly or indirectly support the carrier frame. The moving table is slidably arranged on the ground, and there are two moving tables in parallel. The stand column and the base table are located between the two moving tables. Each moving table is provided with the lead screw mechanism. The sliding block of the lead screw mechanism is provided with a suspension plate. The carrier frame is located between the two suspension plates.

[0006] In the material lifting device, the stand columns are arranged on the base table, and the clamping channel is formed between the adjacent two stand columns. The carrier frame can slide in the clamping channel. The width of the clamping channel is approximately equal to the width of the angle steel. After the angle steel is stacked in the clamping channel, the carrier frame in the clamping channel is used to support the angle steel.

[0007] Meanwhile, since the column and the base are located between the two moving tables, the two moving tables are equivalent to being located at the two ends of the angle steel, and the two moving tables can be moved to any position as required. When the screw mechanism on the moving table operates, the slider (together with the suspension plate) on the screw mechanism will move along the direction of the column. Therefore, when the support frame in the clamping channel is loaded with the angle steel, the movement of the suspension plate can be driven by the operation of the screw mechanism on the moving table. The movement of the suspension plate can drive the support frame (together with the angle steel) to move in the clamping channel. When the angle steel is not placed and needs to be used to support the angle steel, the screw mechanism on the moving table operates to lift the support frame, so that the support frame operates to the channel opening of the clamping channel, and then the angle steel is placed on the support frame, and then the screw mechanism operates again, so that the support frame moves downward (together with the angle steel on the support frame). The angle steel can be stably stacked in the clamping channel. When the angle steel needs to be taken, the screw mechanism drives the support frame to move upward, and when the angle steel is located at the channel opening of the clamping channel, the angle steel can be taken.

[0008] In the device, the column forms a plurality of clamping channels, and each clamping channel can stack the angle steel. The clamping channels are arranged above the base. Therefore, when the device stores the angle steel, the angle steel is arranged and stacked above the base, and the device will not collapse due to loss of balance.

[0009] Optionally, it further includes a folding rod, the folding rod is an L-shaped folding rod, the folding rod is rotatably installed on the suspension plate through a pin shaft, the suspension plate is provided with a receiving groove, the folding rod includes a first rod body and a second rod body, the mass of the first rod body is greater than that of the second rod body, the receiving groove is used for accommodating the first rod body, the suspension plate is provided with a receiving hole, and the top corner of the folding rod is located in the receiving hole.

[0010] Optionally, it further includes a track, the track is arranged on the ground, the moving table is provided with a wheel, the wheel and the track are slidably matched together, and the column is perpendicular to the track.

[0011] Optionally, it further includes a support plate, the support plate is arranged on the base, and the two ends of the support plate are located in the clamping channel. The support plate is used for supporting the support frame.

[0012] Optionally, the support frame is perpendicular to the column.

[0013] Optionally, it further includes a vertical plate, the vertical plate is arranged on the moving table, the vertical plate is provided with a sliding rail, and the slider of the screw mechanism and the sliding rail are slidably matched together.

[0014] The vertical plate is arranged on the moving table, and the sliding rail on the vertical plate and the slider of the screw mechanism are slidably matched together. Therefore, the movement of the slider is stably guided, and the stability of the movement of the slider is improved.

[0015] Optionally, the bearing frame is an isosceles right triangle bearing frame.

[0016] Because the angle of the angle steel is a right angle, the isosceles right triangle bearing frame is used to support the angle steel, and the top angle of the isosceles right triangle is tightly matched with the top angle of the angle steel, so that the stability of the angle steel during stacking can be improved.

[0017] Optionally, the column is a circular column, and the column is perpendicular to the base table.

[0018] The circular column is used to reduce the abrasion of the angle steel during stacking.

[0019] The column forms a plurality of clamping channels, and each clamping channel can stack the angle steel. The clamping channels are arranged above the base table. When the angle steel is stored, the angle steel is arranged and stacked above the base table, and the phenomenon of losing balance and collapsing does not occur. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0027] The present application will be described in detail below with reference to the drawings.

[0028] Example 1

[0029] As shown in the accompanying Figure 1 , accompanying Figure 2 , accompanying Figure 3 and accompanying Figure 4 , a material lifting device, comprising a base table 3, a stand column 2, a moving table 8, a lead screw mechanism 1 and a bearing frame 5, the base table 3 is not less than 2, the base table 3 is fixedly arranged on the ground, and the base table 3 is not in contact with each other, a plurality of stand columns 2 are arranged on each base table 3, and the stand columns 2 are in parallel and not in contact with each other, the adjacent two stand columns 2 on the same base table 3 form a clamping channel 201, the two ends of the bearing frame 5 are slidably connected together in the clamping channel 201, the base table 3 is used for directly or indirectly supporting the bearing frame 5, the moving table 8 is slidably arranged on the ground, the moving table 8 is two, and the two moving tables 8 are in parallel, the stand column 2 and the base table 3 are located between the two moving tables 8, the lead screw mechanism 1 is arranged on each moving table 8, the sliding block 101 of the lead screw mechanism 1 is provided with a suspension plate 11, and the bearing frame 5 is located between the two suspension plates 11.

[0030] In the material lifting device, the stand column 2 is arranged on the base table 3, the clamping channel 201 is formed between the adjacent two stand columns 2, the bearing frame 5 can slide in the clamping channel 201, the width of the clamping channel 201 is substantially equal to the width of the angle steel 12 (the width of the clamping channel is wider than the width of the angle steel and the width of the bearing frame by about 0.5 cm), and after the angle steel 12 is stacked in the clamping channel 201, the bearing frame 5 located in the clamping channel 201 is used to support the angle steel 12.

[0031] At the same time, since the stand column 2 and the base table 3 are located between the two moving tables 8, the two moving tables 8 are equivalent to being located at the two ends of the angle steel 12, and the two moving tables 8 can be moved to any position as needed. When the lead screw mechanism 1 on the moving table 8 operates, the sliding block 101 (together with the suspension plate 11) on the lead screw mechanism 1 will move along the direction of the stand column 2. Therefore, in the device, when the bearing frame in the clamping channel 201 is loaded with the angle steel 12, the movement of the suspension plate 11 can be driven by the operation of the lead screw mechanism 1 on the moving table 8, and the movement of the suspension plate 11 can drive the bearing frame 5 (together with the angle steel 12) to move in the clamping channel 201. When the angle steel 12 is not placed and needs to be used to support the angle steel 12, the lead screw mechanism 1 on the moving table 8 operates to lift the bearing frame 5, so that the bearing frame 5 operates to the opening of the clamping channel 201, and then the angle steel 12 is placed on the bearing frame 5, and then the lead screw mechanism 1 operates again, so that the bearing frame 5 moves downward (together with the angle steel 12 on the bearing frame 5), and the angle steel 12 can be stably stacked in the clamping channel 201. When the angle steel 12 needs to be taken, the bearing frame 5 moves upward under the action of the lead screw mechanism 1, and when the angle steel 12 is located at the opening of the clamping channel 201, the angle steel 12 can be taken.

[0032] In this device, since the column 2 forms multiple clamping channels 201, each clamping channel 201 can hold angle steel 12. The clamping channels 201 are arranged above the base platform 3. Therefore, when storing angle steel 12, the angle steel 12 is stacked above the base platform 3 and will not lose balance and collapse.

[0033] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, it also includes a track 6, which is set on the ground. The moving platform 8 is equipped with wheels 7, which slide together with the track 6. The column 2 is perpendicular to the track 6.

[0034] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, it also includes a support plate 4, which is set on the base platform 3, and both ends of the support plate 4 are located in the clamping channel 201. The support plate 4 is used to support the bearing frame 5.

[0035] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the support frame 5 is perpendicular to the column 2.

[0036] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, it also includes a vertical plate 9, which is mounted on a movable table 8. A slide rail 10 is mounted on the vertical plate 9, and the slider 101 of the lead screw mechanism 1 is slidably engaged with the slide rail 10.

[0037] A vertical plate 9 is set on the moving table 8, and the slide rail 10 on the vertical plate 9 is slidably engaged with the slider 101 of the lead screw mechanism 1. The slide rail 10 is a square slide rail 10, and the square opening on the slider 101 is engaged with the slide rail 10. This is equivalent to playing a stable guiding role in the movement of the slider 101, and improving the stability of the slider 101 when it moves.

[0038] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the support frame 5 is an isosceles right-angled triangular support frame 5.

[0039] Because the angle of angle steel 12 is a right angle, an isosceles right triangle-shaped support frame 5 is used to support angle steel 12. The vertex of the isosceles right triangle fits tightly with the vertex of angle steel 12, which can improve the stability of angle steel 12 when stacked.

[0040] As shown in Figs. 1, 2, 3, 4, 5 and 6, the column 2 is a round column 2, and the column 2 is perpendicular to the base 3. Figure 1 Figure 2 The round column 2 is to reduce the wear of the angle steel 12 when the angle steel 12 is stacked. Figure 3 Figure 4 In the embodiment, the suspension plate 11 is a flat plate.

[0041] In the embodiment, four parallel bases are placed between the two moving tables.

[0042] In the embodiment, all the columns are in parallel state.

[0043] In the embodiment, a motor can be further arranged on the moving table to drive the wheels to rotate on the track, or the moving table can be manually pushed to move on the track.

[0044] Embodiment 2

[0045] As shown in Figs. 1, 2, 3, 4, 5 and 6, the column 2 is a round column 2, and the column 2 is perpendicular to the base 3.

[0046] Embodiment 2

[0047] As shown in Figs. 1, 2, 3, 4, 5 and 6, the column 2 is a round column 2, and the column 2 is perpendicular to the base 3. Figure 5 Figure 6 The difference between the embodiment and the embodiment 1 is that the suspension plate in Fig. 6 is used to replace the flat suspension plate in the embodiment 1. Figure 5

[0048] As shown in Figs. 1, 2, 3, 4, 5 and 6, the column 2 is a round column 2, and the column 2 is perpendicular to the base 3. Figure 5 As shown in Figs. 1, 2, 3, 4, 5 and 6, the column 2 is a round column 2, and the column 2 is perpendicular to the base 3.The first rod body 1301 has a mass greater than that of the second rod body 1302. In the natural state without external contact with the folding rod, the first rod body 1301 is located in the accommodating groove 1101, and the first rod body 1301 is parallel to the ground. The second rod body 1302 is in a state perpendicular to the ground. The second rod bodies 1302 on the two suspension plates 11 are in a parallel state. The distance between the second rod bodies 1302 on the two suspension plates 11 is greater than the length of the carrier 5. The accommodating groove 1101 is used to accommodate the first rod body 1301. The accommodating hole 1102 is arranged on the suspension plate 11. The top corner of the folding rod is located in the accommodating hole 1102. When an external object touches the folding rod, the folding rod will rotate around the pin shaft 14. When the first rod body 1301 contacts the groove bottom of the accommodating groove 1101, it cannot continue to rotate in the original direction. When the second rod body 1302 contacts the hole wall of the accommodating hole 1102, it cannot continue to rotate in the original direction. The sliding blocks 101 of the two screw rod mechanisms 1 are respectively provided with a block as shown in Fig. 7. Figure 5 ​​​The two top corners of the two folding rods are both directed to the carrier 5 after the installation. When in use, the two ends of the carrier 5 are placed on the two suspension plates 11 respectively. If the two suspension plates 11 are at the same height relative to the ground, the two ends of the carrier 5 will not contact the second rod bodies 1302 on the two sides.

[0049] As shown in the device in Embodiment 1, there is a problem in lifting the carrier 5, that is, the two screw rod mechanisms 1 on the two sliding tables are both driven by independent motors, and the control of the two motors can not guarantee synchronization, so the device shown in Embodiment 1 can have the phenomenon that the two suspension plates 11 are not in the same horizontal plane when being lifted, that is, one side of the suspension plate 11 is relatively high in height, and the other side of the suspension plate 11 is relatively low in height. When this situation occurs, the carrier 5 can be overturned together with the angle steel 12.

[0050] Referring to FIG. 1, Figure 6 As shown in FIG. 1, it is assumed that due to objective reasons, the two screw rod mechanisms 1 are in operation, so that the two suspension plates 11 are not in the same horizontal plane, and the left side is low and the right side is high. At this time, the carrier 5 (together with the carried angle steel 12) has a tendency to slide to the left. The carrier 5 sliding to the left will contact the second rod body 1302 on the left side, so that the folding rod on the left side rotates counterclockwise, and after the rod body on the left side rotates, the first rod body 1301 on the left side rotates out of the accommodating groove 1101 and contacts the carrier 5 to lift the carrier 5, so that the two ends of the carrier 5 are at the same height relative to the ground, thereby avoiding the carrier 5 from being overturned when carrying the angle steel.

[0051] Therefore, the lifting device provided in the embodiment has good self-balancing performance in the lifting process, and the carrier is prevented from being overturned when carrying the angle steel.

[0052] The above only describes the preferred embodiments of the present application, and does not limit the patent protection scope of the present application. Any equivalent transformation of the content of the present application specification, direct or indirect application in other related technical fields, is also included in the protection scope of the present application.
