Description

Technical Field

[0001] This application relates to the field of construction, and in particular to a device and method for monitoring and synchronously adjusting the overall lifting level of a steel structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, columns, trusses, and other components made of shaped steel and steel plates. These components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. In the field of overall steel structure installation in building construction, steel structure lifting devices occupy less space and require less steel for temporary support structures during installation. Therefore, the overall lifting method can meet the needs of installations that cannot be completed by general large machinery.

[0003] The existing method for lifting steel structures as a whole involves setting up hydraulic synchronous hoists at predetermined points on the steel structure corridor. The corridor is then lifted to a designated height and welded to the pre-reserved brackets of the main structure. Currently, monitoring during the lifting process primarily involves maintaining the structure at a certain height while it remains stationary. A total station is used to measure the elevation differences between the four corner points of the steel structure and the backsight points, using coordinates set within the building as backsight points. This determines the relative error of the four corner points during the lifting process. The hydraulic synchronous hoists are then adjusted individually to ensure the levelness of the steel structure during lifting. Since the corridor is typically located between two main buildings, two teams are usually selected for simultaneous measurement, with data processed manually at the end.

[0004] Regarding the aforementioned technologies, the inventors believe that having multiple groups of people perform measurements is a waste of manpower. Summary of the Invention

[0005] To save manpower during adjustment and measurement, this application provides a device and method for monitoring and synchronously adjusting the overall lifting level of a steel structure.

[0006] This application provides a device and method for monitoring and synchronously adjusting the overall lifting level of a steel structure, which adopts the following technical solution:

[0007] A device for monitoring and synchronously adjusting the overall lifting level of a steel structure includes: a main structure, a lifting platform mounted on the main structure for lifting the entire steel structure, a lifting assembly connecting the lifting platform and the entire steel structure, and an adjustment assembly for detecting and adjusting the entire steel structure.

[0008] The adjustment assembly includes a first signal transmitter for transmitting position signals, a first signal receiver for receiving signals from the first signal transmitter, a second signal transmitter for transmitting adjustment command signals, and a controller for receiving signals from the second signal transmitter and controlling and adjusting the lifting assembly.

[0009] The system includes multiple first signal transmitters, each located at the lifting assembly, and the signals emitted by each first transmitter are received by the first signal receiver.

[0010] By adopting the above technical solution, when lifting the steel structure as a whole, the lifting components are installed on the lifting platform, which is then installed on the main structure. The steel structure is lifted using the lifting components. After being lifted to a certain position, the position and level of the steel structure are adjusted using the adjustment components. A first signal transmitter and a first signal receiver work together. The first signal receiver receives the signal transmitted by the first signal transmitter to confirm the position of the steel structure as a whole, analyzes the position, and derives an adjustment plan. The adjustment plan is then transmitted to the controller via a second signal transmitter. The controller receives the adjustment plan and controls the lifting components to adjust the steel structure as a whole until the steel structure reaches a level and position within the error range. Throughout the lifting process, the first signal transmitter and the first signal receiver work together to monitor the position of the steel structure as a whole in real time, meeting the need for adjustment at any time. This eliminates the need for multiple teams of personnel to inspect and adjust, saving manpower and improving accuracy.

[0011] Preferably, the first signal transmitter includes a first adjustment base and a transmitter body. The first adjustment base is rotatably fixed near the lifting assembly, and the height of the first adjustment base is adjustable. The transmitter body is used to transmit position signals.

[0012] By adopting the above technical solution, the transmitter body can adjust its horizontal angle and vertical height through the first adjustment seat, so that the signal emitted by the transmitter body can be adjusted in coordination with the first signal receiver.

[0013] Preferably, the transmitter body includes a transmitter housing mounted on the first adjustment seat, and the transmitter housing is movably connected to the first adjustment seat, so that the transmitter housing is adjustable on the first adjustment seat;

[0014] The transmitting housing contains a power supply assembly and a transmitter for transmitting signals, with the signal transmission ports of the transmitter all facing the first signal receiver.

[0015] By adopting the above technical solution, the transmitting shell is movably connected to the first adjustment seat, so that the angle between the transmitting shell and the first adjustment seat can be adjusted to adapt to the use of different types of transmitter bodies. In order to ensure that the signal transmitted by the first signal transmitter can be accurately received by the first signal receiver, the signal transmission port of the transmitter faces the first signal receiver.

[0016] Preferably, the first signal receiver includes a second adjustment base and a receiver body disposed on the second adjustment base. The receiver body is provided with one or more receiving surfaces, which are positioned corresponding to the first signal transmitter.

[0017] By adopting the above technical solution, the second adjustment seat is used to adjust the angle and height of the first signal receiver to facilitate position calibration, and one or more receiving surfaces on the receiver body are used to receive signals transmitted by multiple first signal transmitters.

[0018] Preferably, the receiving surface includes an inner ring and an outer ring, with one inner ring and one outer ring forming a group. The center of each group of inner rings and outer rings coincides. The diameters of the inner ring and the outer ring are determined according to a standard error range. The signal emitted by the first signal transmitter can be received by either the inner ring or the outer ring.

[0019] By adopting the above technical solution, the size of the inner ring is set according to the standard error range. When the signal emitted by the first signal transmitter is within the inner ring, there is no need to adjust the position and angle of the steel structure as a whole. When the signal emitted by the second signal transmitter is within the outer ring, the second signal transmitter sends a command to the controller, thereby controlling the lifting component to adjust the height, position, and angle of the steel structure as a whole.

[0020] Preferably, there is one receiving surface, which is a spherical surface; the receiving surface includes multiple inner rings and multiple outer rings, and the centers of the inner rings and the outer rings are all located on the transverse axis of the spherical surface.

[0021] By adopting the above technical solution, when there is one receiving surface, the spherical surface can receive signals emitted by the first signal transmitter from multiple directions. When the receiving surface is a spherical surface, the two adjacent inner rings cannot overlap, thus avoiding judgment errors.

[0022] Preferably, there are multiple receiving surfaces, all of which are planar and of the same size. The centers of the receiving surfaces, the inner ring, and the outer ring coincide. The number of receiving surfaces is set according to the number of the first signal transmitters.

[0023] By adopting the above technical solution, multiple receiving surfaces are respectively set to correspond to the first signal transmitter, and the position and height of the steel structure as a whole are accurately detected from multiple angles and points.

[0024] Preferably, the edge of the receiver body is close to or coincides with the edge of the outer ring.

[0025] By adopting the above technical solution, in order to save space occupied by the receiver body, save materials and reduce the volume of the receiver body, the edge of the receiver body can be close to or coincide with the edge of the outer ring.

[0026] A measurement method for monitoring and synchronously adjusting the overall lifting level of a steel structure, comprising the following steps:

[0027] Location of steel structure lifting points;

[0028] The first signal transmitting device is set at the same position as the steel structure lifting point.

[0029] Align the signal transmitter of the first signal transmitter with the first signal receiver;

[0030] After receiving the signal from the first signal transmitter, the first signal receiving device checks the error and performs offset data analysis, then transmits the information to the second signal transmitter.

[0031] The second signal transmitting device sends an adjustment command to the controller based on the analyzed information;

[0032] The controller controls the lifting components to adjust the steel structure as a whole until it is level.

[0033] By adopting the above technical solution, the position and level of the steel structure as a whole are monitored in real time through the cooperation of the first signal transmitting device and the first signal receiving device. When the level, angle, etc. of the steel structure as a whole deviate, the second signal transmitting device transmits the adjustment signal to the controller, and the controller controls the lifting component to adjust the steel structure as a whole to a suitable position.

[0034] Preferably, the first signal receiver has an inner ring and an outer ring corresponding to the first signal transmitter;

[0035] If the signal emitted by the first signal transmitter is received by the outer ring, then a signal needs to be emitted to the controller through the second signal transmitter in order to adjust the overall steel structure.

[0036] If the signal emitted by the first signal transmitter is received by the inner ring, no adjustment is required. Attached Figure Description
