Description

Technical Field

[0001] The present invention relates to the field of engineering technology, and specifically refers to an engineering scaffolding with a feeding function. Background Art

[0002] Engineering scaffolding is a very important temporary facility in building construction. It is a working platform erected to ensure the smooth progress of each construction process. It can provide a safe operating place for construction workers, and is also used to place building materials, tools, etc., enabling construction workers to carry out operations such as wall building, painting, and installation at different heights and positions.

[0003] In the prior art, engineering scaffolding generally consists of vertical poles, horizontal bars, scaffold boards, diagonal braces and wall connectors. Before use, the vertical poles, horizontal bars, scaffold boards, diagonal braces and wall connectors are assembled. After that, the staff can carry out construction on the scaffold board. However, in the prior art, the above structures of the engineering scaffolding need to be sequentially spliced, and the staff climbs onto the scaffold board. But when the staff needs to feed materials during the construction using the scaffolding, generally, manual lifting from the ground or the assistance of lifting equipment is required to complete the feeding work. Manual feeding is time-consuming and laborious, and the feeding efficiency is low. When using lifting equipment, it will increase the engineering construction cost, and there will be a situation where personnel accidentally fall when the staff climbs onto the scaffolding, causing casualties.

Inside the base 1, there is a lifting mechanism 4 that passes through the folding frames 2 and is connected to the working plate member 5. At the bottom of the base 1, there are several support members 10. The vertical section of the folding frame 2 is slidably sleeved with a limiting frame 3. On the working plate member 5, there is a local lifting mechanism 6 that can move up and down. Inside the folding frame 2, there is a limiting mechanism 7 for limiting the limiting frame 3;

[0040] Working principle of the present invention: The base 1 serves as the support of the present invention and can transfer the present invention through the support member 10. The folding frame 2 provides fixed longitudinal height support for the present invention, facilitating the rising of the working plate member 5. The limiting frame 3 can fix the two folding frames 2 to keep them stable. The lifting mechanism 4 can lift the working plate member 5 to facilitate the transportation workers. The local lifting mechanism 6 can transport materials during the construction process. The limiting mechanism 7 can fix the limiting frame 3.

[0041] Combined with the attached Figure 11 As shown in the figure, the support member 10 includes a connecting plate 1001 fixed to the bottom of the base 1. A rotating cylinder 1002 is rotatably provided at the bottom of the connecting plate 1001. Two side plates 1003 are provided at the side end of the rotating cylinder 1002. Co-acting members 1004 are provided on the side end faces of the two side plates 1003. A second through groove is provided at the bottom. A universal wheel 1006 is provided between the two side plates 1003. The rotating shaft on the universal wheel 1006 is rotatably connected to the second through groove and can slide in the second through groove, and the rotating shaft passes through the second through groove and is rotatably connected to the bottom of the co-acting member 1004. The top of the side end faces of the two side plates 1003 is hinged to the top of the hinge member 1007. The top of the co-acting member 1004 is hinged to the bottom of the hinge member 1007. A third spring 1009 is connected between the top end of the side plate 1003 and the side end of the co-acting member 1004. A pedal 1008 is provided on the hinge member 1007. A support leg is provided at the bottom of the rotating cylinder 1002;

[0042] Embodiment 1: The support leg includes a bottom cylinder 1010 located at the center of the rotating cylinder 1002. A screw rod 1011 is provided with internal threads in the bottom cylinder 1010. A support 1012 is provided at the bottom of the screw rod 1011. A fixing plate 1013 sleeved outside the screw rod 1011 is fixed at the bottom of the bottom cylinder 1010. A second driving motor 1014 is provided at the side end. A gear 1015 is provided on the second driving motor 1014. A toothed ring 1016 meshing with the gear 1015 is rotatably provided at the bottom of the fixing plate 1013. A nut 1017 is provided at the bottom of the toothed ring 1016. A plurality of sliding rods 1018 passing through the fixing plate 1013 are provided on the support 1012;

[0043] Embodiment 2: The support leg is a fixed cylindrical support rod, and the height of the support rod is not adjustable. The structure is relatively simple and is suitable for a ground with better flatness;

[0044] Working principle of Embodiment 1: Before construction, step on the pedal 1008. The pedal 1008 causes the hinge member 1007 to rotate downward. The hinge member 1007 causes the cooperating member 1004 to move downward. The cooperating member 1004 causes the universal wheel 1006 to move downward. After moving the present invention to a predetermined position through the universal wheel 1006, lift the pedal 1008 to move the universal wheel 1006 upward. At this time, the support 1012 contacts the ground. When it is necessary to adjust the level of the present invention, start the second driving motor 1014 on each support member 10. The second driving motor 1014 causes the gear ring 1016 to rotate through the gear 1015. The gear ring 1016 causes the nut 1017 to rotate. The nut 1017 causes the screw rod 1011 to extend and retract in the bottom cylinder 1010, thereby adjusting the height of the connecting plate 1001, and then achieving the function of adjusting the level of the present invention;

[0045] Before construction in Embodiment 2: It is necessary to use a transportation device or manual labor to transport the present invention to a predetermined position.

[0046] Combined with attached Figure 1 、attached Figure 4 、attached Figure 5 、attached Figure 8 、attached Figure 9 As shown in attached

[0047] During assembly: After the base 1 is in place, manually lift the two folding frames 2 and start the lifting mechanism 4 to move the limiting frame 3 upward. When the limiting frame 3 moves upward, the sliding frame 302 slides outside the rod frame 201. After the limiting frame 3 moves upward in place, fix the limiting frame 3 on the top of the folding frame 2 through the limiting mechanism 7. Then install the anti-tilting shock absorber frame 8 on the folding frame 2 and install the reinforcement frame 9.

[0048] Combined with attached Figure 9 、attached Figure 15 、attached Figure 16As shown in the figure, the limiting mechanism 7 includes a limiting block 701 hinged to the inner side wall of the rod frame 201. There is a slot 203 on the rod frame 201 at the position of the limiting block 701. There is an L-shaped card slot 204 below the slot 203 on the rod frame 201. The bottom end of the limiting block 701 is provided with a resisting rod 702 in contact with the left inner wall of the rod frame 201, and the top end is provided with a connecting ring 708. A first spring 703 and a pulling rope 704 are connected to the connecting ring 708. The top end of the first spring 703 is connected to the right inner wall of the rod frame 201 and the connection position is above the slot 203. The bottom end of the pulling rope 704 is provided with a longitudinal slider 705 that slides up and down inside the rod frame 201. A transverse slider 706 that slides left and right is provided on the longitudinal slider 705. A positioning bolt 707 is provided on the transverse slider 706, and the positioning bolt 707 is located in the card slot 204;

[0049] Working principle of the limiting mechanism 7: When the limiting frame 3 moves upward, the sliding frame 302 contacts the limiting block 701 and squeezes the limiting block 701 into the slot 203. At this time, the first spring 703 is stretched. When the sliding frame 302 is separated from the limiting block 701, the first spring 703 resets to make the limiting block 701 return to extend out of the slot 203. After the limiting frame 3 moves upward, it will press on the limiting block 701. At this time, the limiting block 701 is fixed under the action of the contact between the resisting rod 702 and the rod frame 201 and limits the limiting frame 3 at the top of the rod frame 201;

[0050] When the limiting frame 3 needs to move downward: Pull the positioning bolt 707 downward to make the longitudinal slider 705 move downward. When the longitudinal slider 705 moves downward until the transverse slider 706 contacts the bottom of the card slot 204, pull the positioning bolt 707 to the left to make the transverse slider 706 move rightward and get stuck. During this process, the longitudinal slider 705 makes the limiting block 701 contract into the slot 203 through the pulling rope 704. At this time, the limiting frame 3 can move downward smoothly. During the process of the limiting block 701 contracting into the slot 203, the limiting block 701 will push up the limiting frame 3 a certain distance and then move downward.

[0051] Combined with the attached Figure 8 、attached Figure 9 、attached Figure 10 As shown in the figure, the anti-tilting shock-absorbing frame 8 includes a first clamp 801 sleeved on the outside of the rod frame 201. A second clamp 802 is provided below the first clamp 801. A support rod 803 is hinged on the first clamp 801. The bottom of the support rod 803 contacts the ground. A reinforcing rod 804 is hinged on the second clamp 802. The end of the reinforcing rod 804 is hinged with an adjusting frame 805 sleeved on the outside of the support rod 803. A locking bolt 806 is provided on the adjusting frame 805;

[0052] Both the rod holder 201 and the side end of the base 1 are provided with connection blocks. The reinforcement frame 9 includes a reinforcement member 901. The two reinforcement members 901 are cross-distributed. A first through groove 902 is provided at the bottom of the reinforcement member 901. A second spring 903 is provided in the first through groove 902. The end of the second spring 903 is connected to a sliding sleeve 904 arranged in the first through groove 902. The sliding sleeve 904 is rotatably connected to the connection block on the base 1. A positioning hook 905 that is clamped with the connection block on the rod holder 201 is provided at the top of the reinforcement member 901;

[0053] Working principle of the anti-tilting and shock-absorbing frame 8: When installing the anti-tilting and shock-absorbing frame 8, the anti-tilting and shock-absorbing frame 8 is integrally formed and not disassembled. The first clamp 801 and the second clamp 802 are sleeved on the rod holder 201 at a predetermined position and fixed by bolts. Since the distance and height between the first clamp 801 and the second clamp 802 can be changed, the inclination angle of the support rod 803 can also be changed, which is convenient for adjusting to the optimal anti-tilting position. Since the bottom of the support rod 803 contacts the ground, the center of gravity of the present invention will be reduced, thereby improving the anti-seismic and anti-tilting performance;

[0054] Working principle of the reinforcement frame 9: When installing the reinforcement frame 9, the two reinforcement members 901 can be directly rotated relative to each other, and the two reinforcement members 901 will automatically cross. When the positioning hook 905 moves to the connection block on the rod holder 201, push the reinforcement member 901 upward so that the positioning hook 905 can hook the connection block on the rod holder 201. After hooking, release the hand, and the connection block on the rod holder 201 and the positioning hook 905 are rotationally clamped under the action of the second spring 903.

[0055] Combined with attached Figure 4 、attached Figure 5 、attached Figure 6 、attached Figure 7 、attached Figure 12 、attached Figure 13 As shown in attached

[0056] The lifting mechanism 4 includes a rotating rod 401 located inside the base 1. Both ends of the rotating rod 401 are provided with screw rod ends 402 located inside the base 1. Both ends of the first wire roller 404 are provided with limit blocks 405 located inside the base 1. The limit blocks 405 are located outside the first wire rope 406 wound around the first wire roller 404. A worm gear 403 meshed with the screw rod end 402 is provided at the center of the first wire roller 404. A first transmission wheel 202 is provided at the top of the rod holder 201. The first wire rope 406 is in rolling connection with the first transmission wheel 202;

[0057] The working plate member 5 includes a working platform 501. At the center of the working platform 501, there is an inner frame 502 with a hollow interior. A number of second conveyor wheels 504 are provided on the inner frame 502. The local lifting mechanism 6 includes second wire rollers 606 located on both sides of the inner frame 502. Second steel wire ropes 608 are wound around both ends of the second wire rollers 606. The second steel wire ropes 608 are in rolling connection with the second conveyor wheels 504 and their ends are connected to a moving plate 609 located below the inner frame 502. A number of clamping mechanisms 14 for clamping and fixing the moving plate 609 are provided on the inner frame 502;

[0058] The local lifting mechanism 6 includes a first driving motor 601 located on the working platform 501. A first bevel gear 602 is provided on the first driving motor 601. A transmission rod 604 is provided on one side of the first bevel gear 602. A second bevel gear 603 meshing with the first bevel gear 602 is provided on the transmission rod 604, and third bevel gears 605 are provided at both ends. A fourth bevel gear 607 meshing with the third bevel gear 605 is provided at the end of the second wire roller 606. Cover plates 503 are hinged at both ends of the working platform 501. The inner ends of the cover plates 503 have the same contour as the inner frame 502;

[0059] Working principle of the lifting mechanism 4: When lifting the working plate member 5, the rotating rod 401 is driven. The rotation of the rotating rod 401 causes the screw rod end 402 to drive the first wire roller 404 to wind the first steel wire rope 406 through the worm gear 403. Since the first steel wire rope 406 is connected to the working plate member 5 through the first conveyor wheel 202, at this time, the first steel wire rope 406 causes the working plate member 5 to rise. When the working plate member 5 rises to the top, a rod member can be inserted into the working plate member 5 through the rod rack 201, thereby fixing the working plate member 5;

[0060] Before lifting the limiting frame 3, the working plate member 5 needs to be lifted first. During the process, it is necessary to manually hold or use tools to keep the rod rack 201 vertical. After the working plate member 5 rises to the top, the lifting auxiliary member 13 below the limiting frame 3 is locked. Then, the working plate member 5 is lowered. During the process, the first steel wire rope 406 on the side away from the working plate member 5 rises, and then the lifting auxiliary member 13 rises, so as to achieve that the first steel wire rope 406 pushes the limiting frame 3 upward through the lifting auxiliary member 13. After the limiting frame 3 rises to the predetermined position, the lifting auxiliary member 13 is unlocked. Then, when the working plate member 5 is lifted again, loading can be carried out, that is, transporting personnel and materials;

[0061] Working principle of the local lifting mechanism 6: When it is necessary to convey materials from the ground to the working plate 5, start the first driving motor 601, which drives the third bevel gear 605 to rotate through the first bevel gear 602, the second bevel gear 603, and the transmission rod 604. The third bevel gear 605 drives the second wire roller 606 to rotate through the fourth bevel gear 607, so that the second wire roller 606 releases the second wire rope 608. Before this, the clamping mechanism 14 needs to be disengaged from the moving plate 609. At this time, the moving plate 609 can move down to the ground, and the ground staff can place materials on the moving plate 609. Then, start the reverse rotation of the first driving motor 601 to make the moving plate 609 rise to the initial position, achieving the function of quickly conveying materials. After moving up, the moving plate 609 is clamped and fixed by the clamping mechanism 14.

[0062] Combined with the attached Figure 7 , attached Figure 14 As shown, the clamping mechanism 14 includes a frame body 1401 fixed on the outer end face of the inner frame 502. An insertion rod 1402 passing through the inner frame 502 is arranged inside the frame body 1401. A jack 610 is arranged on the moving plate 609. The moving plate 609 is fixed by inserting the insertion rod 1402 into the jack 610. One end of the insertion rod 1402 is provided with a fourth spring 1403. A connecting rod 1404 connected to the insertion rod 1402 is arranged inside the fourth spring 1403. The end of the connecting rod 1404 passes through the frame body 1401 and is connected with a handle 1405 at the end;

[0063] Working principle of the clamping mechanism 14: Pull the handle 1405 outwards, and through the connecting rod 1404, make the insertion rod 1402 move outwards until it disengages from the jack 610 on the moving plate 609. At this time, the fourth spring 1403 is compressed. Just release the handle 1405 when the moving plate 609 moves down. The bottom of the part where the insertion rod 1402 is inserted into the jack 610 is in an arc shape.
