DETAILED DESCRIPTION

[0032] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0033] In the embodiment, as shown in FIGS. 1-2, the present application provides a technical solution of a vertical take-off and landing hoisting device for concrete high-altitude construction, which comprises a hoisting structure 2. A gear two 29 is rotatably installed inside an equipment shell 21 in the hoisting structure 2. A forward-reverse motor 212 is fixedly connected to one side inside the equipment shell 21. A gear box 211 installed at an output end of the forward-reverse motor 212 is used to change the speed of the rotation force output by the forward-reverse motor 212. A gear three 210 fixedly connected to an output end of the gear box 211 is engaged with the gear two 29. Therefore, the rotation force output by the forward-reverse motor 212 is transmitted to the gear three 210 under the action of the gear box 211. The gear three 210 drives the engaged gear two 29 to rotate. The rotating gear two 29 drives the engaged gear one 28 to rotate. The support shaft 27 fixedly connected inside the gear one 28 rotates under the support of the equipment shell 21. The winding frame 213 fixedly connected to the outside of the support shaft 27 rotates.

[0034] A steel wire rope 26 is fixedly connected to the winding frame 213. Part of the steel wire rope 26 is wound around the outside of the winding frame 213. Therefore, the winding frame 213 can be controlled to wind or unwind the steel wire rope 26 by controlling the forward-reverse motor 212 to work in forward rotation or reverse rotation. One end of the steel wire rope 26 extends to the outside of the equipment shell 21 through the inner wall of the equipment shell 21 away from the side of the forward-reverse motor 212. The end of the steel wire rope 26 is a heavy object hoisting end. Under the action of the fixed heavy object and the deflection of the pulley one 214 fixedly connected to the outside of the equipment shell 21, the heavy object hoisted by the one end of the steel wire rope 26 moves vertically up and down during the winding and unwinding of the steel wire rope 26.

[0035] In the embodiment, as shown in FIG. 3, a plurality of support wheels 23 are fixedly connected to both sides of the equipment shell 21. The support wheels 23 are arranged inside the adjacent horizontal guide rails 11 and can roll inside the horizontal guide rails 11. The position of the hoisting structure 2 can be adjusted. The hoisting structure 2 is more labor-saving when changing position. The distance of transporting concrete materials is reduced. The concrete materials hoisted up by the hoisting structure 2 can be conveniently placed nearby. The concrete material hoisting work is orderly carried out.

[0036] After the position adjustment of the hoisting structure 2 is completed, the power supply of the hoisting structure 2 is turned on, the controller 5 fixedly connected on one side of the equipment shell 21 controls the hydraulic cylinder one 215 fixedly connected at the bottom of the equipment shell 21 to work, the hydraulic cylinder one 215 pushes the friction plate 25 fixedly connected at the bottom to move downward, so that the friction plate 25 moves downward and contacts the building to limit the movement of the hoisting structure 2; and a plurality of telescopic rods 24 are fixedly connected between the top of the friction plate 25 and the bottom of the equipment shell 21, the telescopic rods 24 can extend and retract without affecting the downward movement of the friction plate 25, and the telescopic rods 24 share the force received by the hydraulic cylinder one 215, thereby reducing the possibility of deformation damage of the hydraulic cylinder one 215.

[0037] As shown in FIGS. 3-5, the transverse support structure 1 is composed of two transverse guide rails 11 and two longitudinal mounting frames 14 as a skeleton, after the components of the transverse support structure 1 are carried into the high-rise building, first, the two support frames one 19 fixedly connected at the bottom of the first longitudinal mounting frame 14 are contacted with the building floor, the support frames one 19 are fixedly installed on the building by using the plurality of threaded holes 110 formed on the support frames one 19, square insertion slots 12 and two circular insertion slots 13 are formed at both ends of the two transverse guide rails 11, square insertion plates 16 and two circular insertion rods 17 are fixedly connected at both ends of one side of the longitudinal mounting frame 14, so the square insertion slots 12 formed on the transverse guide rails 11 are aligned with the square insertion plates 16 fixed on the longitudinal mounting frame 14, and the circular insertion slots 13 formed on the transverse guide rails 11 are aligned with the circular insertion rods 17 fixed on the longitudinal mounting frame 14, then the two transverse guide rails 11 are inserted into the longitudinal mounting frame 14 fixed on the building, the plurality of support wheels 23 fixed on both sides of the equipment shell 21 are pushed into the two transverse guide rails 11, so that the support wheels 23 are supported by the transverse guide rails 11, and the equipment shell 21 is installed between the two transverse guide rails 11; since the support frames two 111 fixedly connected at the bottom of the transverse guide rails 11 are in contact with the building floor, the transverse guide rails 11 can support the equipment shell 21 at this time.

[0038] After the square insertion plates 16 and the circular insertion rods 17 fixed on the second longitudinal mounting frame 14 are inserted into the square insertion slots 12 and the circular insertion slots 13 formed on the transverse guide rails 11, the longitudinal mounting frame 14 is fixed on the building, and a guide rail structure meeting the movement of the hoisting structure 2 is assembled, so that the hoisting structure 2 can reciprocate within a certain range, the transverse support structure 1 can be dispersedly carried, and the difficulty of carrying the vertical take-off and landing hoisting device composed of the transverse support structure 1, the hoisting structure 2, the multifunctional self-locking structure 3, the support arm 4 and the like is reduced.

[0039] And the bottom of the extension rail 112 is also fixedly connected with a support frame two 111, and one end of the extension rail 112 is also fixedly connected with a square plug plate 16 and two circular plug rods 17. Before assembling the second longitudinal mounting frame 14 with the transverse rail 11, the square plug plate 16 and the circular plug rod 17 fixedly connected with the extension rail 112 are inserted into the square slot 12 and the circular slot 13 of the transverse rail 11, and then the transverse rail 11 and the extension rail 112 constitute a new length of rail. In addition, the other end of the extension rail 112 is also provided with a square slot 12 and two circular slots 13, so that two extension rails 112 can also be assembled together. After installing a proper number of extension rails 112 on one side of the two transverse rails 11 according to the building space, the second longitudinal mounting frame 14 is assembled with the two extension rails 112 at the end, so that different lengths of rail structures can be assembled according to the building space to meet the construction needs.

[0040] As shown in FIGS. 1 and 6, two fixed frames one 41 are fixedly connected on one side of the equipment shell 21. The fixed seat 44 fixedly connected to one end of the fixed frame two 43 is inserted between the two fixed frames one 41, and the inclination angle of the fixed frame two 43 is adjusted. Since the fixed frame one 41 and the fixed seat 44 are both provided with two multi-surface grooves 42, and the multi-surface groove 42 is an eight-surface structure, after aligning the multi-surface groove 42 of the fixed seat 44 with the multi-surface groove 42 of the fixed frame one 41;

[0041] The U-shaped frame composed of the two multi-surface columns 45 and the fixed frame three 47 fixedly connected between the two multi-surface columns 45 is taken up, the one end of the multi-surface column 45 is inserted into the multi-surface groove 42 of the fixed seat 44, and then the one end of the multi-surface column 45 is inserted into the multi-surface groove 42 of the fixed frame one 41. When the square vertical slot 46 at the top of the two multi-surface columns 45 is inserted into the square plate, the fixed seat 44 and the two fixed frames one 41 can be assembled together.

[0042] The hydraulic cylinder two 48 is fixedly connected inside the fixed frame two 43, the one end of the piston of the hydraulic cylinder two 48 is fixedly connected with the moving beam 49, and the pulley two 410 is fixedly installed at one end of the moving beam 49, which is used for changing the direction of the steel wire rope 26, so that one end of the steel wire rope 26 moves up and down; the controller 5 controls the working of the hydraulic cylinder two 48, that is, the distance between the pulley two 410 fixedly connected at one end of the moving beam 49 and the equipment shell 21 is controlled, the distance between the pulley two 410 and the building is controlled, the bottom end weight of the steel wire rope 26 changed by the pulley two 410 has sufficient rising space; when the weight rises to the bottom near the pulley two 410 and the weight transversely moves to the transverse support structure 1 and is not blocked by the building, the hydraulic cylinder two 48 can be controlled to work synchronously with the lifting structure 2, and in the process that the lifting structure 2 winds the steel wire rope 26, the hydraulic cylinder two 48 retracts to drive the moving beam 49 and the pulley two 410 to move close to the lifting structure 2, at this time, the moving speed of the pulley two 410 and the winding speed of the steel wire rope 26 reach dynamic balance, so that the weight transversely moves to the transverse support structure 1 without changing the up-down position, so that the weight is directly lifted into the building, avoiding the safety hazard that the staff pulls and carries the concrete material at the edge of the building.

[0043] And the multi-faceted groove 42 and the multi-faceted column 45 are both multi-faceted structures, so the inclination angle of the fixed frame two 43 and the fixed seat 44 can be controlled, the fixed seat 44 and the fixed frame one 41 are fixedly installed together through the U-shaped frame, and a certain space is arranged between the two multi-faceted columns 45, so that the fixed frame one 41 and the fixed seat 44 can be accommodated when the U-shaped frame works, so the U-shaped frame can still meet the installation needs of the fixed seat 44 and the fixed frame one 41; in the state that the hydraulic cylinder two 48 does not work and extend, the pulley two 410 fixed at one end of the moving beam 49 has a certain distance from the building floor, so as to provide space for the weight to transversely move into the building.

[0044] And the external support 411 is arranged outside the fixed frame two 43, the external support 411 is fixedly connected with the pulley two 410, and the external support 411 increases the stability of the pulley two 410 and the fixed frame two 43.

[0045] In summary, during the assembly of the transverse support structure 1, the lifting structure 2 is installed inside the transverse support structure 1, the position of the lifting structure 2 is adjusted, and then the lifting structure 2 and the controller 5 are powered on, the hydraulic cylinder one 215 fixedly connected at the bottom of the equipment shell 21 is controlled by the controller 5 to work, the position of the lifting structure 2 is fixed, then the support arm 4 is installed on one side of the lifting structure 2, the pulley two 410 in the support arm 4 changes the direction of the steel wire rope 26, so that one end of the steel wire rope 26 moves away from the building in the air to provide space for the lifting of the heavy object; a vertical lifting device assembled by the transverse support structure 1, the lifting structure 2 and the support arm 4 is provided, which can be conveniently and flexibly disassembled and used, and meets the vertical lifting of concrete, paint, wire and other materials with smaller weight in building construction which is not suitable for large lifting equipment.

[0046] As shown in FIGS. 2-12, the multifunctional self-locking structure 3 is installed in the equipment shell 21, the flow guide one 32 is fixedly connected to one side of the oil storage tank 31 at the bottom, the impeller 33 rotatably installed in the flow guide one 32 is fixedly connected to the gear two 29 at one end extending out of the flow guide one 32, so that during the unwinding of the steel wire rope 26 by the lifting structure 2, the gear two 29 is reversed to drive the impeller 33 to rotate, and the force generated by the rotating impeller 33 in the flow guide one 32 transports the lubricating oil in the flow guide one 32 to the inside of the return pipe one 327 fixedly connected to the flow guide one 32. Although the inner diameter of the flow guide two 34 fixedly connected in the return pipe one 327 is smaller than the inner diameter of the return pipe one 327, in the normal working state of the lifting structure 2, the rotating speed of the gear two 29 and the impeller 33 is slow, at this time the flow rate of the lubricating oil is slow, and the inner hole of the flow guide two 34 meets the flow needs of the lubricating oil, and the hydraulic oil is returned to the inside of the oil storage tank 31 through the return pipe two 326 fixedly connected between one end of the return pipe one 327 and the oil storage tank 31.

[0047] When the lifting structure 2 is damaged and the heavy object falls out of control to cause the gear two 29 to rotate quickly, at this time the rotating speed of the gear two 29 and the impeller 33 is fast, the inner hole of the flow guide two 34 does not meet the flow needs of the hydraulic oil, the hydraulic pressure at the bottom of the relief valve 37 arranged on one side of the flow guide two 34 increases, part of the hydraulic oil rushes through the relief valve 37 into the three-way valve 39, at this time the pressure sensor 38 fixedly connected to the output end of the relief valve 37 detects the increase of the hydraulic pressure, the controller 5 electrically connected to the pressure sensor 38 works to issue an alarm to remind the staff of the fault;

[0048] And the lubricating oil output from the pressure relief valve 37 into the tee valve 39 inside from the tee valve 39 inside the constant open end discharge, and the hydraulic push assembly guide piece three 310 is fixedly installed between the constant open end of the tee valve 39 and the inlet of the check valve 311, the lubricating oil enters the check valve 311 inside through the guide piece three 310, the lubricating oil enters the guide piece four 312 inside fixedly connected to the outlet of the check valve 311, the check valve 311 restricts the backflow of the lubricating oil into the guide piece three 310; and the hydraulic telescopic rod 313 fixedly connected to one end of the guide piece four 312, at this time the hydraulic pressure in the hydraulic telescopic rod 313 increases, the hydraulic telescopic rod 313 extends to push the connecting frame one 314 fixedly connected to the piston end to move downward;
