[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] As Figures 1-6 shown, an automatic lifting platform for elevator steel structure installation proposed by the present utility model includes a fixed frame 1, a platform frame 2 that slides vertically along the fixed frame 1, and a sling 3 installed at the top of the fixed frame 1 to drive the platform frame 2 to slide vertically. The platform frame 2 includes a platform bottom plate 21, four connecting columns 22 fixed at the four corner positions on the upper surface of the platform bottom plate 21, and a platform top plate 23 fixed at the tops of the four connecting columns 22. The platform top plate 23 is connected to the bottom end of the sling 3, and the top end of the sling 3 is connected to a hoist installed at the top of the fixed frame 1. The hoist and its connection with the sling 3 are prior art and will not be elaborated here. In addition, the fixed frame 1 is composed of four vertical columns, and the columns are connected and fixed by cross beams. Vertical slide rails are provided on the opposite surfaces of the columns, and sliding grooves matching the slide rails are opened on the sides of the platform bottom plate 21 and the platform top plate 23, so that the platform frame 2 can be lifted and lowered smoothly under the action of the hoist.

[0036] In this embodiment, the lifting platform includes a platform slide plate 5 that slides horizontally on the upper surface of the platform bottom plate 21, and the platform slide plate 5 is used to place the steel structure to be transported. A trapezoidal groove 51 is provided on one side of the platform slide plate 5 away from the floor 4, which is convenient for personnel to stand in the case of co-transporting people and goods.

[0037] Furthermore, the lifting platform further includes connection handles 7 and a binding belt 8. There are two pairs of connection handles 7 in total, and each pair is respectively fixedly connected to two opposite surfaces of the trapezoidal groove 51. One end of the binding belt 8 is fixedly or rotatably sleeved with one side of the connection handle 7. Since the steel structure usually has transverse and longitudinal support arms, the other end of the filling plate 9 can be wound around the steel structure and the corresponding connection handle 7 on the other side, and then fixed through the mother and son magic tape provided on the binding belt 8 itself, so as to fix the steel structure on the platform slide plate 5.

[0038] In addition, the lifting platform includes a pushing and transferring mechanism 6 for realizing the horizontal sliding of the platform slide plate 5, and the sliding direction is close to or away from the wall opening of the floor 4. The pushing and transferring mechanism 6 includes a transverse slide rail 61 fixedly connected to the upper surface of the platform bottom plate 21 and a long strip slider 62 fixedly connected to the lower surface of the platform slide plate 5 and horizontally sliding with the transverse slide rail 61. By the horizontal sliding of the long strip slider 62 on the transverse slide rail 61, the platform slide plate 5 is close to or away from the wall opening of the floor 4, so as to realize the transfer of the steel structure between the construction floor and the platform slide plate 5. In addition, the pushing and transferring mechanism 6 further includes a lead screw 63 rotatably connected to the upper surface of the platform bottom plate 21 through a pair of bearings, a lead screw sleeve 64 fixed to the front end of the lower surface of the platform slide plate 5 and threadedly engaged with the lead screw 63, and a motor 67 fixedly connected to the upper surface of the platform bottom plate 21 and coaxially fixed with the output shaft of the lead screw 63. The output shaft of the motor 67 drives the lead screw 63 to rotate, and the lead screw 63 makes the platform slide plate 5 move backward (towards the direction of the floor 4) or forward (away from the direction of the floor 4) through the threaded engagement with the lead screw sleeve 64. The operation of the motor 67 can be controlled by personnel nearby or remotely. Since it is prior art, it will not be elaborated here. The pushing and transferring mechanism 6 further includes a guide shaft 65 connected to the upper surface of the platform bottom plate 21 through a pair of bearings and a guide shaft sleeve 66 fixed to the front end of the lower surface of the platform slide plate 5 and slidably sleeved with the guide shaft 65. Through the sliding sleeve connection of the guide shaft sleeve 66 and the guide shaft 65, further guidance can be provided for the translation of the platform slide plate 5 on the basis of the transverse slide rail 61 and the long strip slider 62.

[0039] Furthermore, the lifting platform further includes a filling plate 9 for filling the trapezoidal groove 51. When transporting people and goods together, the filling plate 9 can be stored under the platform slide plate 5 as shown in Figure 5 to expose the trapezoidal groove 51 for people to stand. When transporting the steel structure alone, the filling plate 9 can be placed above the platform slide plate 5 as shown in Figure 6 to fill most of the trapezoidal groove 51 to provide more placement space for the steel structure. Specifically, a filling plate slider 91 is fixedly connected to one side surface of the filling plate 9. Taking Figure 6 as a reference, this side surface refers to the lower surface. Upper and lower slide grooves 52 and 53 matching the filling plate slider 91 are respectively formed on the upper and lower surfaces of the platform slide plate 5. And, a handle 92 is fixedly connected to one end surface of the filling plate 9, a limit ring 921 is fixedly connected to the middle section of the handle 92, a rear limit hole 54 capable of being vertically aligned with the limit ring 921 is formed at one end of the platform slide plate 5, and a front limit hole 211 capable of being vertically aligned with the limit ring 921 is formed at one end of the platform bottom plate 21 away from the rear limit hole 54. Specifically: when transporting people and goods together, since it is necessary to expose the trapezoidal groove 51, the filling plate 9 is placed as shown in Figure 5As shown, it is placed on the lower surface of the platform slide plate 5. At this time, the filling plate slider 91 is horizontally slidably engaged with the lower chute 53, and slides until the limit ring 921 is vertically aligned with the rear limit hole 54, and then it can be fixed by stringing and connecting with long connectors such as pin shafts and screw shafts. When transporting steel structures alone, there is no need to expose the trapezoidal groove 51. At this time, the filling plate 9 can be placed as Figure 6 shown on the upper surface of the platform slide plate 5 (rotate 180° horizontally to swap the positions of the left and right sides). At this time, the filling plate slider 91 is horizontally slidably engaged with the upper chute 52 and the lower chute 53, and slides until the limit ring 921 is vertically aligned with the front limit hole 211, and then it can be fixed by stringing and connecting with long connectors such as pin shafts and screw shafts.

[0040] The working principle of this embodiment is as follows: Place the steel structure to be transported on the platform slide plate 5 and fix it with the strap 8. The hoist at the top of the fixing frame 1 works, and drives the platform frame 2 to rise through the sling 3 to lift the steel structure to the floor 4 where construction is to be carried out. Subsequently, through the pushing and transferring mechanism 6, the platform slide plate 5 is translated in the direction close to the floor 4, so that the platform slide plate 5 drives the steel structure thereon to extend into the floor 4. Since the site in the floor 4 is relatively open, whether it is manual unloading by workers or using the lifting device installed in the floor 4, the steel structure can be easily unloaded from the platform slide plate 5;

[0041] In addition, this device can be applied to different scenarios such as co-transporting people and goods and transporting people or goods alone. When co-transporting people and goods or transporting people alone, the platform slide plate 5 can be removed or people can stand at the trapezoidal groove 51. It should be noted that anti-falling protection measures need to be taken when transporting people. Such measures are commonly used in lifting equipment and will not be elaborated here. When transporting goods alone (such as steel structures), the filling plate 9 can be placed as Figure 6 shown on the upper surface of the platform slide plate 5. At this time, the filling plate slider 91 is horizontally slidably engaged with the upper chute 52 and the lower chute 53, and slides until the limit ring 921 is vertically aligned with the front limit hole 211, and then it can be fixed by stringing and connecting with long connectors such as pin shafts and screw shafts. At this time, the filling plate 9 fills most of the trapezoidal groove 51, which can provide more placement space for the steel structure. And, when co-transporting people and goods or transporting people alone as described above, the filling plate 9 can be placed as Figure 5 shown on the lower surface of the platform slide plate 5. At this time, the filling plate slider 91 is horizontally slidably engaged with the lower chute 53, and slides until the limit ring 921 is vertically aligned with the rear limit hole 54, and then it can be fixed by stringing and connecting with long connectors such as pin shafts and screw shafts, which can reserve more space for people to stand.

[0042] In summary, by providing a platform skateboard 5 that can slide horizontally on the platform bottom plate 21, the steel structure can be transferred into the floor 4 in a horizontal pushing manner, avoiding potential safety hazards to personnel caused by the shaking of the steel structure during traditional hoisting and transfer; by providing a trapezoidal groove 51 on the platform skateboard 5, a standing position can be provided for personnel during the co-transport of people and goods without being affected by the translation of the platform skateboard 5 for standing stability; in addition, through the design of the filling plate 9, the trapezoidal groove 51 can be filled when only transporting the steel structure, so as to provide more placement space for the steel structure, and the filling plate 9 can be stored under the platform skateboard 5 during the co-transport of people and goods.

[0043] The above specific embodiments are merely several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
