Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building construction equipment technology, specifically relating to a construction equipment structure suitable for modular pressurized building installation. Background Technology

[0002] Modular pressurized buildings consist of compartments of varying sizes, including standard cabins, transition areas, corridors, connecting passages, stairwells, and large spaces. During assembly, a single truck crane is typically used for lifting. However, in actual lifting operations, the uneven weight distribution and skewed center of gravity of the compartments cause them to tilt after lifting, making alignment difficult. While using specialized rigid lifting equipment can solve this problem, conventional equipment cannot accommodate all the different sizes of the modular pressurized building's compartments. Equipping multiple sizes of lifting equipment would increase costs and make operation inconvenient. Utility Model Content

Therefore, they should not be construed as limitations on this application.

[0033] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0034] This embodiment provides a construction equipment structure suitable for modular pressurized building installation, such as... Figures 1-2 As shown, it mainly includes: a lifting frame 1, a fixed lug 2, and an adjustable lug 3;

[0035] The lifting frame 1 consists of an upper square frame 11 and a lower lifting plate 12. The frame longitudinal beams 13 on both sides of the upper square frame 11 are evenly provided with a plurality of equally spaced pin holes 14 for installing the fixed lug 2 and the adjustable lug 3.

[0036] The lower suspension plate 12 has multiple equally spaced suspension holes 15 on both sides for attaching shackles or lifting rings to hook the four corner suspension points of the modular pressurized building body.

[0037] One end of the frame longitudinal beam 13 is equipped with a fixed lug 2, and the other end is equipped with an adjustable lug 3. The top lifting lugs of both the fixed lug 2 and the adjustable lug 3 are provided with lifting ring connection holes 4, and lifting wire ropes 5 (or chains, slings) are threaded through them.

[0038] like Figures 3-4 As shown, the fixing ear seat 2 includes an ear seat frame 21 sleeved on the frame longitudinal beam 13. The ear seat frame 21 is groove-shaped, and a circular through hole 22 adapted to the size of the pin hole 14 is opened on the side of the ear seat frame 21. After the fixing ear seat 2 slides along the frame longitudinal beam 13 to a preset position, it is fixedly connected to the corresponding pin hole 14 on the frame longitudinal beam 13 through the cooperation of the circular through hole 22 and the pin 23.

[0039] The mounting position of the fixing lugs on the longitudinal beam of the frame can be quickly adjusted by using a pin connection, so as to achieve large-span equal-space adjustment of the fixing lugs.

[0040] like Figures 5-6 As shown, the adjustable ear seat 3 includes a first fixed frame 32 and a second fixed frame 33 sleeved on the frame longitudinal beam 13, and an ear seat frame 31 is provided between the first fixed frame 32 and the second fixed frame 33. The first fixed frame 32, the second fixed frame 33 and the second ear seat frame 31 are all groove-shaped.

[0041] Both the first fixed frame 32 and the second fixed frame 33 have circular through holes 41 on their sides that are adapted to the size of the pin holes 14. The first fixed frame 32 and the second fixed frame 33 are fixedly connected to the corresponding pin holes 14 on the frame longitudinal beam 13 through the circular through holes 41 and the pins 42. The ear seat frame 31 is slidably sleeved on the frame longitudinal beam 13 between the first fixed frame 32 and the second fixed frame 33.

[0042] The installation position of the adjustable lugs on the longitudinal beam of the frame can be quickly adjusted by means of a pin connection, so as to achieve large-span equal-space adjustment of the adjustable lugs.

[0043] Furthermore, the outer surfaces of the ear seat frame 2 31, the fixing frame 1 32, and the fixing frame 2 33 are respectively provided with connecting block 1 34, connecting block 2 35, and connecting block 36. The rear end face of the connecting block 1 34 is fixedly connected with a lead screw nut 37. The lead screw 38 passes through the connecting block 2 35, the connecting block 1 34, the lead screw nut 37, and the connecting block 36 in sequence and then exits from the rear end face of the connecting block 36.

[0044] Furthermore, the middle part of the lead screw 38 is threadedly engaged with the lead screw nut 37, and both ends are respectively supported on the middle through holes of the connecting block 2 35 and the connecting block 36. The end of the lead screw 38 that passes through the connecting block 36 is fixedly connected to a dial wheel 39, and a lever 40 is provided on the dial wheel 39.

[0045] like Figure 7 As shown, a plurality of insertion holes 43 are evenly provided on the outer circumferential surface of the dial 39 for inserting the dial lever 40;

[0046] Specifically, by moving the lever 40 to drive the dial wheel 39 to rotate the lead screw 38 axially, the lead screw nut 37, under the action of the thread, drives the connecting block 34 and the ear seat frame 31 to slide together along the longitudinal beam 13 of the frame. The stepless and precise adjustment of the position of the adjustable ear seat is realized through the lead screw and nut mechanism.

[0047] This application combines two adjustment methods—large-span fixed spacing adjustment and stepless precise adjustment—to achieve large-span precise adjustment of the hook spacing. The overall structure is compact, convenient and flexible to use, and can adapt to the hoisting of modular pressurized building compartments of various sizes and specifications. It can also adjust the lug spacing in a timely manner according to the shift of the compartment's center of gravity, keeping the compartment's center of gravity and the hook center on the same vertical line to achieve balanced hoisting.

[0048] The specific usage method is as follows:

[0049] 1) Estimating the initial installation position: Based on the dimensions of the modular pressurized building cabin and the span of the lifting points, estimate the initial installation position of the fixed lugs and adjustable lugs on the upper square frame, and fix the fixed lugs and adjustable lugs to the corresponding pin holes on the longitudinal beams of the frame using pins.

[0050] 2) Hooking the compartment to be lifted: Select suitable lifting holes on the lower lifting plate and use shackles or lifting rings to hook the four corner lifting points of the compartment;

[0051] 3) First trial lift: Based on the initial installation position, the first trial lift of the compartment is carried out. If the tilt of the compartment during the first trial lift exceeds the expected range, the distance between the lifting lugs is adjusted by a large span and then a second trial lift is carried out. If the tilt of the compartment during the first trial lift is within the expected range, the distance between the lifting lugs is adjusted steplessly and precisely.

[0052] 4) Large-span equidistant adjustment of the lifting lug spacing: Based on the cabin tilt during the first trial lift, adjust the mounting pin hole positions of the fixed lug and adjustable lug on the frame longitudinal beam to make large-span adjustment of the lifting lug positions. At the same time, adjust the length of the lifting ropes at each lifting point to roughly correct the center of gravity shift during cabin lifting.

[0053] 5) Second trial lift: Based on the position of the lifting lugs after the large span adjustment, a second trial lift of the cabin is carried out. If the cabin tilt during the second trial lift still exceeds the expected range, the above large span adjustment steps are repeated until the tilt is within the expected range. If the cabin tilt during the second trial lift is within the expected range, the stepless precise adjustment of the lifting lug spacing continues.

[0054] 6) Stepless precise adjustment of the lug spacing: Based on the specific offset of the cabin's center of gravity during the last trial lift, the lever of the corresponding adjustable lug is moved to make the lead screw rotate axially. Through the threaded engagement, the rotational motion of the lead screw is converted into the linear motion of the lead screw nut, which in turn drives the lug frame of the adjustable lug to slide along the longitudinal beam of the frame. This precisely adjusts the position of the adjustable lug, ensuring that the center of the crane hook coincides with the center of gravity of the cabin, thus achieving load balance during the actual lifting.

[0055] Optionally, the number of fixed lugs 2 and adjustable lugs 3, as well as their installation positions on the lifting frame 1, can be arbitrarily selected according to the size of the pod to be lifted and the number of lifting points.

[0056] Furthermore, all parts of this application that are not described in detail are the same as or implemented using existing technology.

[0057] The above embodiments are only used to illustrate the design concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The protection scope of this utility model is not limited to the above embodiments. Therefore, all equivalent changes or modifications made based on the principles and design ideas disclosed in this utility model are within the protection scope of this utility model.
