Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude hoisting, and in particular to a high-altitude hoisting device and method for a heavy steel structure corridor. Background Art

[0002] With the rapid development of modern industrial buildings, large-scale public facilities, and urban transportation systems, the demand for high-altitude installation of heavy-duty steel structure corridors, which serve as crucial pathways connecting different buildings or process units, is increasing. These corridors typically feature large spans, wide cross-sections, and heavy weights (up to tens of tons). During the hoisting process, high-precision docking is required, and working space is limited, placing extremely high demands on construction safety and installation accuracy.

[0003] Currently, traditional heavy steel corridor hoisting is often performed using a dual crane system combined with manual positioning. During the hoisting process, simple support frames or temporary blocks are often used to protect the corridor ends to prevent collisions with the target building. However, these devices are limited in functionality, lacking buffering and intelligent adjustment capabilities, and are difficult to adapt to the precise docking requirements under complex working conditions.

[0004] Furthermore, after the corridor is spliced, the reliability and long-term safety of the overall connection are directly affected by the uniform stress distribution of the structure and the presence of localized gaps or uneven loading. Existing technologies typically separate structural stress monitoring from the hoisting device, requiring the subsequent installation of independent stress monitoring equipment to assess splice quality. This makes it difficult to integrate hoisting and monitoring operations, resulting in suboptimal construction safety and efficiency.

[0005] To this end, a heavy steel structure corridor high-altitude lifting device and method are provided to solve the above-mentioned problems. Summary of the Invention

DETAILED DESCRIPTION

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1 In order to solve the problems of high collision risk, poor docking accuracy and low construction safety caused by the large volume, heavy weight and limited space of the existing hoisting process, please refer to Figures 1-3 The present invention provides a heavy steel structure corridor high-altitude hoisting device, comprising: Buffer assembly 1, used to wrap the end of the corridor to achieve buffering, anti-collision and positioning functions during the hoisting process, and to prevent the corridor from rigidly contacting the target building; A support frame 2 is provided at the end of the corridor and is used to install the buffer assembly 1; The intelligent positioning component 3 is provided on the buffer component 1 and is used to monitor the relative position information between the end of the corridor and the target building in real time during the hoisting process; Among them, the support frame 2 includes a fixed clamp 201 that is detachably fixed on the corridor, a movable clamp 202 that is movably mounted on the corridor, and a driving member 203. The driving member 203 is used to drive the movable clamp 202 to drive the buffer assembly 1 along the axial direction of the corridor away from the target building to expose the corridor overlap position. The driving member 203 is fixed on the fixed clamp 201.

[0023] When in use, the fixed hoop 201 is installed on the end of the steel structure corridor through stud bolts or other detachable connectors, the movable hoop 202 is sleeved on the corridor and connected to the driving member 203, the main body of the buffer component 1 is installed on the movable hoop 202, and inflated to the set pressure so that it completely wraps the end of the corridor to form a flexible protective layer to prevent rigid collision with the surrounding structure during the lifting process. Through the collaborative operation of the two cranes, the two ends of the corridor are lifted synchronously to achieve smooth lifting and aerial translation in a horizontal posture. During the lifting process, the intelligent positioning component 3 collects the three-dimensional relative position information between the end of the corridor and the target building in real time. When approaching the target installation position, the control system determines whether the current posture meets the docking conditions based on the data fed back by the intelligent positioning component 3. If the docking requirements are met, the system first controls the buffer component 1 to gradually deflate, so that the corridor slowly descends while maintaining a horizontal state until a safe gap is maintained between the buffer component and the building. Subsequently, the control system controls the drive component 203 to drive the movable clamp 202 to move backward along the axis of the corridor, driving the buffer component 1 to retreat synchronously, gradually exposing the end structure of the corridor. When the buffer component 1 is completely retreated to a position that does not affect the overlap, the end of the corridor falls precisely into the preset overlap structure of the building. After the overlap is completed, the device is dismantled for reuse.

[0024] like Figure 4As shown, the buffer assembly 1 includes a plurality of airbag bodies 101 uniformly distributed along the circumference of the corridor end, a connecting pipe 102 for connecting adjacent airbag bodies 101, and an inflation and deflation unit for wrapping the corridor end and providing multi-point buffering protection. The connecting pipe 102 realizes the air pressure balance between each airbag body 101; the inflation and deflation unit includes an air pump 103, a multi-way piece 104 provided at the air outlet of the air pump 103, and an inflation solenoid valve 105 and a deflation solenoid valve 106. The air pump 103 is fixed on the fixed clamp 201, the multi-way piece 104 is connected to at least one airbag body 101 through an air pipe, the inflation solenoid valve 105 is provided on the air pipe, and the deflation solenoid valve 106 is provided on the top of the airbag body 101.

[0025] Before the lifting operation, the control system starts the air pump 103, and the gas is distributed to each airbag 101 through the multi-channel piece 104. At the same time, the inflation solenoid valve 105 is opened to achieve synchronous inflation of multiple airbags 101. During the lifting process, if the intelligent positioning component 3 detects that the corridor is close to the target building and meets the docking conditions, the control system issues a command to close the inflation solenoid valve 105 and open the deflation solenoid valve 106, so that the gas in the airbag 101 is slowly discharged through the top exhaust port to achieve controllable deflation.

[0026] In order to adapt to the use of corridors of different specifications, such as Figure 5 As shown, the fixed clamp 201 is composed of a plurality of first angle plates 201a connected end to end, and a plug plate 201e is provided on one side of each first angle plate 201a, and a slot matching the plug plate 201e is provided on the other side to realize a detachable connection between adjacent first angle plates 201a; a support ear 201b is fixed on the outer side of the first angle plate 201a, and a fastener 201c for locking the fixed clamp 201 to the corridor is provided between the support ears 201b on adjacent first angle plates 201a; a rubber pad 201d is provided on the inner side of the first angle plate 201a, which is used to increase the friction with the corridor surface and prevent damage to the corridor structure during the clamping process.

[0027] The movable clamp 202 is composed of four second angle plates 202a connected end to end. The plug-in structure of the second angle plate 202a is the same as the plug-in structure of the first angle plate 201a; the end of the second angle plate 202a is fixed with a guide light axis 202b that is movable through the first angle plate 201a, which is used to guide the movable clamp 202 to move smoothly along the axial direction of the corridor to prevent deflection or jamming. The inner side of the second angle plate 202a is provided with a rubber roller 202c that is in rolling contact with the corridor.

[0028] During the installation process, the four first angle plates 201a are first spliced ​​into a ring structure by plugging the plug plates 201e into the slots, and are sleeved on the predetermined position at the end of the corridor. Subsequently, the adjacent support ears 201b are locked by fasteners 201c such as double-headed high-strength bolts, so that the fixed clamp 201 is firmly fixed to the outer wall of the corridor, and the four second angle plates 202a are assembled into a movable clamp 202 in the same plug-in manner, and are sleeved on the corridor. The guide light axis 202b passes through the corresponding through hole on the fixed clamp 201 to form a sliding guide structure. When the driving member 203 is started, it pushes the movable clamp 202 to move axially along the corridor. The guide light axis 202b is supported by the fixed clamp 201 to achieve linear guidance, ensuring that there is no deflection or lateral displacement during the movement. At the same time, the rubber roller 202c maintains rolling contact with the outer wall of the corridor, significantly reducing the sliding friction resistance and improving the driving efficiency and movement smoothness.

[0029] The fixed clamp 201 and the movable clamp 202 adopt a split and detachable structural design, which is not only convenient for on-site installation and disassembly, but also significantly improves the adaptability of the device to steel structure corridors of different cross-sectional sizes and shapes. This design makes the overall structural specifications flexible and adjustable, and can adapt to the use of corridors of different specifications. It has strong reusability and effectively reduces construction costs.

[0030] like Figure 4 As shown, the intelligent positioning component 3 includes a ranging sensor 301 and a camera 304 embedded on the end face of the airbag body 101 facing the target building, an angle sensor 302 embedded on the top surface of the upper airbag body 101, and a height sensor 303 embedded on the bottom surface of the lower airbag body 101. All sensors are embedded in the airbag body 101 to avoid damage from external collisions; there are at least two ranging sensors 301, which are diagonally distributed to measure the distance between different positions at the end of the corridor and the building, respectively, to form a spatial distance matrix, and to avoid errors caused by single-point measurement.

[0031] The distance measuring sensor 301 is used to collect the relative distance between the end of the corridor and the building in real time. The camera 304 works together with the distance measuring sensor 301 to obtain visual image information of the docking area. The angle sensor 302 is used to monitor the pitch angle or tilt posture of the corridor during the hoisting process to determine whether it is in a horizontal docking posture. The height sensor 303 is used to measure the height of the corridor and the vertical height difference between the corridor and the target overlapping surface; the intelligent positioning component 3 realizes all-round real-time monitoring of the corridor position and posture, significantly improves the hoisting accuracy, and solves the problems of low positioning accuracy and docking difficulty caused by the existing hoisting relying on manual observation or a single sensor, thereby improving construction safety and automation level.

[0032] Example 2 On the basis of the first embodiment, in order to solve the problem that the existing lifting device lacks the ability to monitor the structural stress state after docking is completed, Figures 1-3 、 Figure 6 As shown, the device also includes a monitoring component 4 provided on the movable clamp 202 for continuously monitoring the corridor after the lifting is completed; the cross-sectional structure of the corridor is square, and the monitoring component 4 is provided with three groups, distributed on the bottom surface and both sides of the corridor, for monitoring the vertical bearing force and lateral force of the corridor in the overlapped state, such as wind load and lateral thrust caused by thermal expansion and contraction.

[0033] The monitoring component 4 includes a sub-bag 401, on the side of which the sub-bag 401 faces the building, at least two diagonally distributed pressure sensors 402 are provided. When the sub-bag 401 is inflated, the pressure sensors 402 abut against the building. A switch 403 and an inflation connector 404 are provided on the other side of the sub-bag 401. The inflation connector 404 is connected to other outlets of the multi-way piece 104 through an air pipe, and the air pipe is also provided with an inflation solenoid valve 105. A control module 405, a wireless transmission module 406 and a power supply module 407 are provided inside the sub-bag 401.

[0034] A support plate 202d is fixed on the movable clamp 202, and the support plate 202d is detachably fixedly connected to the auxiliary bag 401. The detachable fixed connection can be a snap connection or a magnetic connection, so that the movable clamp 202 can be disconnected from the monitoring component 4 when moving.

[0035] The driving member 203 drives the movable clamp 202 to drive the monitoring assembly 4 to move along the corridor in the axial direction until the auxiliary capsule 401 reaches the side of the overlapping area between the corridor and the target building, and then the movement is stopped, the control system opens the corresponding inflation electromagnetic valve 105, and the auxiliary capsule 401 is filled with appropriate gas through the multi-way component 104 in the main gas path system and the connecting gas pipe, so that the auxiliary capsule 401 is inflated and tightly adheres to the overlapping interface between the corridor and the building, the pressure sensor 402 arranged on the outside of the auxiliary capsule 401 is in full contact with the surface of the building, effective pressure transmission is realized, and the movable clamp 202 is further controlled to move by the driving member 203, because the auxiliary capsule 401 is filled between the corridor and the building, under the action of tension, the detachable connection structure between the monitoring assembly 4 and the support plate 202d is separated, so that the monitoring assembly 4 is left in place in the overlapping area, and the buffer assembly 1 and the support frame 2 are removed after hoisting is completed; the monitoring assembly 4 enters an independent working mode after being separated, the two pressure sensors 402 arranged at an angle collect pressure data at different positions of the overlapping surface in real time, which are used to judge whether there is a phenomenon of partial load, local void or uneven stress, the control module 405 collects and processes the sensor signals at regular time intervals, the data are uploaded to the ground monitoring terminal in real time through the built-in wireless transmission module 406, remote, continuous and unattended structure stress state monitoring is realized, and the power module 407 provides power for the whole system to support continuous work for several days; when it is confirmed that the structure stress is stable and there is no abnormal change, the opening and closing component 403 can be closed through a remote command or manual operation on site, the internal gas pressure of the auxiliary capsule 401 is released, and then the whole monitoring assembly 4 is taken out from the overlapping area, and is repeatedly used after cleaning and maintenance.

[0036] Embodiment three On the basis of the embodiment one and the embodiment two, the application further provides a hoisting method for a heavy steel structure corridor, comprising the following steps. S1, the main bodies of the two buffer assemblies 1 are respectively installed on the movable clamps 202 at the two ends of the corridor, and are inflated to a set pressure to completely wrap the end portions of the corridor to form a flexible protection layer; S2, the two cranes are used to cooperatively hoist the two ends of the corridor synchronously to realize smooth lifting and air translation in a horizontal posture; In the hoisting process, the intelligent positioning assembly 3 collects three-dimensional relative position information between the end portions of the corridor and the target building in real time; S3, when the corridor approaches the target installation position, the control system judges whether the current posture meets the butt joint condition according to the data fed back by the intelligent positioning assembly 3, if the butt joint requirement is met, the control system controls the buffer assembly 1 to gradually deflate to control the corridor to gradually descend to a preset butt joint height in a horizontal state; S4, the driving member 203 drives the buffer assembly 1 to move away from the target building along the axial direction of the corridor to expose the overlapping position of the corridor; S5. During the backward movement of the buffer assembly 1, the monitoring assembly 4 integrated thereon moves forward until it reaches the predetermined position on the side of the overlap area between the corridor end and the target building. The movement is stopped and the air is inflated to the set pressure to ensure that the monitoring assembly 4 is fully in contact with the building contact surface. Then, the movable clamp 202 is driven to move backward. Under the action of the pulling force, the monitoring assembly 4 is separated from the support frame 2, and the monitoring assembly is retained in place. S6. Accurately overlap the end of the corridor to the preset overlap structure of the building to complete the structural docking. The retained monitoring component 4 starts working to achieve continuous monitoring of the stress state of the structure after docking.

[0037] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
