Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and particularly relates to a type-I and type-II connecting device for attaching a construction elevator and an installation method thereof. Background Art

[0002] Currently, a construction elevator usually uses a wall-attaching frame to fix the guide rail on the outside of a building. However, due to construction environment restrictions in the early and middle stages of nuclear island construction, the elevator cannot be normally connected to the nuclear island shell through the wall-attaching frame. To solve the installation of the elevator in the early and middle stages of nuclear island construction, a patent application (CN214569941U) provides an attachment passage device for a nuclear island construction elevator, which effectively realizes the installation of the elevator in the early and middle stages of nuclear island construction. However, the current connecting device has a poor connection and fixation effect on the human passage standard section and the elevator standard section. Therefore, a connecting device and an installation method thereof that can enhance the connection effect and ensure the safety of elevator installation and use are needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a type-I and type-II connecting device for attaching a construction elevator and an installation method thereof. By using the type-I connecting device and the type-II connecting device in cooperation, the stable connection between the human passage standard section and the construction elevator standard section can be effectively realized, thereby ensuring the safety of elevator installation and use.

[0012] When the connection points of the standard sections of the construction hoist are staggered from the ear plates on the standard sections of the human-shaped passage, a type-II connection device is used to connect the standard sections of the human-shaped passage and the standard sections of the construction hoist. To solve the above technical problems and achieve the corresponding technical effects, by installing and using the type-I connection device and the type-II connection device, the present invention can effectively and safely connect and fix the standard sections of the human-shaped passage and the standard sections of the construction hoist. Compared with the traditional connection device, the type-I connection device and the type-II connection device are designed for the standard sections of the human-shaped passage and the standard sections of the construction hoist, so their connection effect is better, the connection strength that can be achieved is higher, and the installation and use safety of the hoist is higher.

[0039] Embodiment 1

[0040] Such asFigure 1 As shown in the figure, a method for installing a connecting device for attaching a construction elevator includes the following steps:

[0041] Step 1: Determine the position of the connection point and select a Type I connecting device or a Type II connecting device.

[0042] Step 2: Fix the connecting ear plate 3 to the ear plate provided on the outer side of the standard section of the human-shaped passage.

[0043] Step 3: Connect one side of the rigid connecting piece to the connecting ear plate 3.

[0044] Step 4: Connect the other side of the rigid connecting piece to the connecting fastener 5.

[0045] Step 5: Nest the standard section of the construction elevator within the connecting fastener 5.

[0046] When the connection point of the standard section of the construction elevator is flush with the ear plate on the standard section of the human-shaped passage, use a Type I connecting device to connect the standard section of the human-shaped passage and the standard section of the construction elevator.

[0047] When the connection point of the standard section of the construction elevator is offset from the ear plate on the standard section of the human-shaped passage, use a Type II connecting device to connect the standard section of the human-shaped passage and the standard section of the construction elevator. In this embodiment, the connecting device can be disassembled into multiple individual components and transported to the connection point for splicing and installation, thereby achieving the connection effect between the standard section of the human-shaped passage and the standard section of the construction elevator. Before the splicing and installation of the connecting device, first, preset ear plates on the outer horizontal bar of the standard section of the human-shaped passage, and then use methods such as bolt connection or pin connection to connect the preset ear plates to the connecting ear plate 3. Then, fix the rigid connecting piece to the ear plate through high-strength bolts 4. After the rigid connecting piece is stable, fix the connecting fastener 5 to the rigid connecting piece, so as to be able to build a connecting device for connecting and fixing the standard section of the construction elevator on the outer side of the human-shaped passage. Finally, nest the connecting guide rail of the construction elevator within the connecting fastener 5, and then the construction elevator can be effectively attached to the human-shaped passage, solving the construction elevator erection work in the early and middle stages of nuclear island construction. At the same time, during the installation and erection process, the positional relationship between the preset ear plates and the connection points on the standard section of the construction elevator not only includes being flush but also being offset from each other. Therefore, in this embodiment, two structural forms of connecting devices are provided. When the connection point of the standard section of the construction elevator is flush with the ear plate on the standard section of the human-shaped passage, use a Type I connecting device to connect the standard section of the human-shaped passage and the standard section of the construction elevator; when the connection point of the standard section of the construction elevator is offset from the ear plate on the standard section of the human-shaped passage, use a Type II connecting device to connect the standard section of the human-shaped passage and the standard section of the construction elevator.

[0048] Embodiment 2

[0049] Based on Embodiment 1, this embodiment provides a type-I connecting device.

[0050] As Figure 2 , Figure 3 shown, a type-I connecting device includes a type-I rigid connecting member 1, a connecting ear plate 3 and a connecting fastener 5. The connecting ear plate 3 is fixed to one side of the type-I rigid connecting member 1, and the connecting fastener 5 is fixed to the other side of the type-I rigid connecting member 1. In this embodiment, in order to achieve the connection effect between the construction hoist standard section and the ear plate on the human-shaped passage standard section when the connection points of the construction hoist standard section are flush with the ear plates on the human-shaped passage standard section, the type-I rigid connecting member 1 can install the connecting ear plate 3 and the connecting fastener 5 at the same horizontal height, so as to achieve the connection effect in the above-mentioned flush situation.

[0051] The type-I rigid connecting member 1 includes a first connecting section 11 and second connecting sections 12 arranged at both ends of the first connecting section 11. The second connecting sections 12 extend away from the side where the connecting ear plate 3 is fixed, and the axes of the first connecting section 11 and the second connecting sections 12 are located in the same horizontal plane. In this embodiment, the first connecting section 11 and the second connecting sections 12 are preferably of an integrally formed structural form, so as to enhance the structural strength of the type-I rigid connecting member 1, and further improve the structural strength of the entire connecting device, so as to improve safety. Specifically, second connecting sections 12 are arranged at both ends of the first connecting section 11, and a connecting fastener 5 is arranged on each of the two second connecting sections 12. At the same time, in order to improve the structural stability, the two connecting fasteners 5 (i.e., the second connecting sections 12 at both ends) should be symmetric about the midline of the first connecting section 11; and the connecting ear plate 3 should also be symmetrically arranged into two about the midline of the first connecting section 11. And a backing plate can also be added between the connecting ear plate 3 and the first connecting section 11, so as to increase the contact area, reduce the pressure, prevent loosening and protect the first connecting section 11 and the high-strength bolt 4.

[0052] Both the first connecting section 11 and the second connecting sections 12 are provided with bolt holes. The connecting ear plate 3 is fixed to the first connecting section 11 through a high-strength bolt 4, and the connecting fastener 5 is fixed to the second connecting section 12 through a high-strength bolt 4. In this embodiment, all components are connected by high-strength bolts 4, so each fastener can be disassembled and spliced, so the connecting device can be reused multiple times, thereby reducing the construction cost. Among them, the connection method using high-strength bolts 4 can also be replaced by connection methods such as pin connection that can achieve disassembly and splicing. However, among many alternative structures, the connection method of using high-strength bolts 4 in combination with bolt holes for fixed connection is more stable, so as to improve the stability and safety of the entire connecting device.

[0053] As Figure 6As shown in the figure, the connecting fastener 5 includes a rigid clamping member 51 and a disc fastener 52. The rigid clamping member 51 is clamped to the second connecting section 12 and fixed by high-strength bolts 4. The disc fastener 52 is used to connect to the standard section of the construction elevator. In this embodiment, the rigid clamping member 51 and the disc fastener 52 are connected into an integral body by welding. When splicing, the two side plates of the rigid clamping member 51 are clamped on the second connecting section 12, and the high-strength bolts 4 are passed through the bolt holes and tightened to achieve the connection effect between the connecting fastener 5 and the second connecting section 12. At this time, the connecting guide rail of the construction elevator can be nested in the disc fastener 52 and locked, and then the installation of the construction elevator can be completed by relying on this human-shaped passage.

[0054] Embodiment 3

[0055] On the basis of Embodiment 1, this embodiment provides a type-II connecting device.

[0056] As Figure 4 、 Figure 5 As shown in the figure, a type-II connecting device includes a type-II rigid connecting member 2, a connecting ear plate 3, and a connecting fastener 5. The connecting ear plate 3 is fixed to one side of the type-II rigid connecting member 2, and the connecting fastener 5 is fixed to the other side of the type-II rigid connecting member 2. In this embodiment, in order to achieve the connection effect between the standard section of the construction elevator and the standard section of the human-shaped passage when the connection points of the standard section of the construction elevator are staggered from the ear plates on the standard section of the human-shaped passage, the type-II rigid connecting member 2 can install the connecting ear plate 3 and the connecting fastener 5 at different horizontal heights, so as to achieve the connection effect in the above-mentioned flush situation.

[0057] The type-II rigid connecting member 2 includes a horizontal section 21 and vertical sections 22 provided at both ends of the horizontal section 21, and the axes of the horizontal section 21 and the vertical sections 22 are perpendicular to each other. In this embodiment, the vertical section 22 can adjust the installation position of the connecting fastener 5 to the position of the connection point on the standard section of the construction elevator, so as to complete the connection effect between the standard section of the construction elevator and the standard section of the human-shaped passage. The horizontal section 21 and the vertical sections 22 are also preferably of an integrally formed structural form, so as to enhance the structural strength of the type-II rigid connecting member 2, and further improve the structural strength of the entire connecting device, thereby improving safety. Specifically, vertical sections 22 are provided at both ends of the horizontal section 21, and one or more connecting fasteners 5 are provided on each of the two vertical sections 22. In this embodiment, it is preferred that a connecting fastener 5 is provided at both the upper and lower ends of each vertical section 22, for a total of four connecting fasteners 5, so as to enhance the connection effect between the standard section of the construction elevator and the standard section of the human-shaped passage. And a backing plate can also be added between the connecting ear plate 3 and the horizontal section 21 to increase the contact area, reduce the pressure, prevent loosening, and protect the horizontal section 21 and the high-strength bolts 4.

[0058] Both the horizontal section 21 and the vertical section 22 are provided with bolt holes, and a plurality of bolt holes are uniformly opened in the vertical section 22 along the vertical direction; the connecting ear plate 3 is fixed to the horizontal section 21 by high-strength bolts 4, and the connecting fastener 5 is fixed to the vertical section 22 by high-strength bolts 4. Similarly, in this embodiment, all components are connected by high-strength bolts 4, so each fastener can be disassembled and spliced, and the connecting device can be reused multiple times, thereby reducing the construction cost. Among them, the connection method using high-strength bolts 4 can also be replaced by connection methods such as pin connection that can achieve disassembly and splicing. However, among many alternative structures, the connection method of using high-strength bolts 4 in combination with bolt holes for fixed connection is more stable, thereby improving the stability and safety of the entire connecting device. Opening a plurality of bolt holes in the vertical section 22 enables the setting position of the connecting fastener 5 to be adjusted according to the position of the connection point during the installation construction process, so as to better achieve the connection effect between the connecting fastener 5 and the connection point on the construction elevator.

[0059] As Figure 6 shown, the connecting fastener 5 includes a rigid clamping member 51 and a disc fastener 52. The rigid clamping member 51 is clamped to the vertical section 22 and fixed by high-strength bolts 4. The disc fastener 52 is used to connect to the standard section of the construction elevator. Similarly, in this embodiment, the rigid clamping member 51 and the disc fastener 52 are connected into a whole by welding. When splicing, the two side plates of the rigid clamping member 51 are clamped on the vertical section 22, and the high-strength bolts 4 are passed through the bolt holes and tightened to achieve the connection effect between the connecting fastener 5 and the vertical section 22. At this time, the connecting guide rail of the construction elevator can be nested in the disc fastener 52 and locked, and then the installation of the construction elevator can be completed by relying on this human-shaped passage.

[0060] A support rib plate 23 is provided at the connection between the horizontal section 21 and the vertical section 22. In this embodiment, the setting of the support rib plate 23 can effectively enhance the structural strength of the II-shaped rigid connector 2, thereby enhancing the strength of the entire device and improving the stability and safety of the connecting device.

[0061] The above-mentioned specific implementation manners have further detailed the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above is only the specific implementation manner of the present invention and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
