Description

TECHNICAL FIELD

[0001] The present application relates to the hoisting technology field, in particular to a steel structure hoisting device and method. BACKGROUND

[0002] In the construction of steel structure buildings, the hoisting operation of large steel components is one of the core links, and its safety, efficiency and positioning accuracy directly affect the progress and quality of the project. The traditional hoisting device usually adopts fixed hoist arms or simple mobile structures, which have the following technical bottlenecks: the traditional hoist arms are mostly fixed in length or adjustable in a single direction, which is difficult to adapt to the hoisting needs of steel components of different sizes and positions in complex spaces.

[0003] When the hoisting position deviates, the hoisting equipment needs to be repeatedly disassembled or moved as a whole, resulting in low construction efficiency and easy safety risks caused by human operation errors. The hoist arm and support structure in the existing device are mostly rigidly connected, lacking a dynamic force adaptation mechanism. When hoisting heavy components, the cantilever end is prone to deflection and deformation, causing local stress concentration on the main supporting beam, and even causing structural instability. In addition, the support mechanism lacks real-time feedback on load changes, making it difficult to actively disperse the stress. The existing technology mostly relies on manual observation or a single electronic sensor (such as a pressure sensor) to judge the load state, which has high misjudgment rate and response lag. Especially in harsh working conditions such as vibration and high temperature, the sensor is easily disturbed and cannot reliably trigger the protection mechanism. The locking mechanism is delayed when overloaded, which can easily cause equipment damage or accidents. SUMMARY

[0004] The purpose of the present application is to provide a steel structure hoisting device that can solve the problems raised in the background art.

[0005] The technical solution of the present application is as follows:

[0006] The present application provides a steel structure hoisting device, which comprises a hoist main body fixed on the top of a floor, a plurality of main supporting beams are arranged around the top wall of the hoist main body, the side wall of one of the main supporting beams is provided with two mutually perpendicular hoist arms, the end of each hoist arm is provided with a hydraulic lifting device, an adjusting seat is installed on the side wall of the main supporting beam, an inclined support for supporting the two hoist arms is installed on the outer side wall of the adjusting seat, a monitoring mechanism for detecting the force of the hoist arm is arranged between the inclined support and the adjusting seat, a positioning mechanism for driving the adjusting seat to move along the extension direction of the main supporting beam is arranged on the main supporting beam, a locking mechanism linked with the monitoring mechanism is arranged on the adjusting seat, and the locking mechanism is used to fix the adjusting seat on the outer side wall of the main supporting beam.

[0007] In some technical solutions of the present invention, the monitoring mechanism includes two locking seats installed on the outer side walls of the adjustment seat, a locking groove is provided on the side walls of the locking seat, an adjusting wheel connected to the oblique support is rotatably provided in the locking groove, an installation groove is provided in the locking groove along the extension direction of the main support beam, a monitoring part is slidably provided in the installation groove, and adjustment springs abutting against the monitoring part are installed on both sides of the locking groove, and the wheel surface of the adjusting wheel abuts against the outer side wall of the monitoring part.

[0008] In some technical solutions of the present invention, the positioning mechanism includes a first telescopic structure installed in the main support beam, the telescopic end of the first telescopic structure is connected to the adjustment seat, and a guide mechanism for guiding the movement of the adjustment seat is provided on the outer wall of the main support beam.

[0009] In some technical solutions of the present invention, the locking mechanism includes a cam structure installed on the rotating shaft of the adjusting wheel, a locking rod is inserted into the mounting groove, an adjusting spring is sleeved on the outer wall of the locking rod, the adjusting spring is connected to the locking groove, and a plurality of limiting holes are equidistantly provided on the outer wall of the main support frame, and the locking rod passes through the adjusting seat and is placed in the limiting hole.

[0010] In some technical solutions of the present invention, a plurality of adjusting teeth are arranged around the outer wall of the adjusting wheel, and a plurality of limiting teeth are arranged equidistantly on the outer wall of the monitoring component, wherein a portion of one adjusting tooth is embedded between any two adjacent limiting teeth.

[0011] In some technical solutions of the present invention, an adjusting beam is slidably provided on the side wall of the boom, a driving structure for driving the adjusting beam to reciprocate is provided inside the boom, and a supporting structure for supporting the adjusting beam is provided on the oblique support.

[0012] In some technical solutions of the present invention, the driving structure includes a second telescopic structure installed in the boom, the telescopic end of the second telescopic structure is connected to the adjusting beam, and the hydraulic lifting device is installed on the free end of the adjusting beam.

[0013] In some technical solutions of the present invention, a third telescopic structure connected to the oblique support is installed on the outer wall of the main supporting beam, and a guide groove is opened on the outer wall of the boom, in which a support seat connected to the oblique support is slidably provided.

[0014] In some technical solutions of the present invention, the supporting structure includes an outer support frame installed on the outer side wall of the oblique support, and a fourth telescopic structure connected to the oblique support is installed on the side wall of the outer support frame.

[0015] Compared with the prior art, the present invention has at least the following advantages or beneficial effects: the monitoring mechanism combines a mechanical adjustment wheel with an electronic sensor (displacement sensor, pressure sensor) to dually detect the stress state of the boom, and avoids slipping through the meshing design of the adjustment teeth and the limit teeth to ensure detection accuracy.

The outer support frame uses a fourth telescopic structure to expand the contact area, distributing local pressure and preventing crushing. A mechanical adjustment wheel is combined with electronic sensors (displacement sensor, first / second pressure sensor) to reduce the error of a single detection method and adapt to high-vibration environments. The two vertical booms form a cantilever structure through the main support beam. Combined with the extended support of the diagonal support and the outer support frame, the upper limit of the single lifting weight is significantly increased. The adjustment mechanism uses a first telescopic structure (such as a hydraulic cylinder) to drive the adjustment seat to slide along the main support beam. A guide mechanism (guide rails or rollers) ensures a straight horizontal movement trajectory, achieving stepless horizontal adjustment of the boom. A second telescopic structure within the boom drives the adjustment beam to extend and retract, expanding the lifting range. A third telescopic structure pushes the diagonal support along the guide groove, dynamically adapting the adjustment beam length to maintain the optimal support angle.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0029] Example

[0030] The present invention provides a steel structure hoisting device, such as Figures 1-9As shown, including fixed to the top of the floor 1, the hanger body 7, the hanger body 7 is made of steel profile by welding and bolted together, its overall rectangular frame structure. The top wall of the hanger body 7 is provided with a plurality of main support beams 3, the number of main support beams is at least 4, and the four main support beams 3 are all fixed to the top of the hanger body 7 by bolts, and the two form a fitting structure, which can improve the stability of the above structure connection. One of the side walls of the main support beam 3 is provided with two mutually perpendicular hangers 4, one of which extends outward after penetrating the side wall of the main support beam 3, and the other extends outward after penetrating the main support beam 3 and the hanger 4, so that the two form a cantilever structure, thereby improving the carrying capacity of the two hangers 4 when lifting the object. The end of the hanger 4 is provided with a hydraulic lifting device 6, which is a prior art, and is clamped at the free end of the hanger 4 by a clamping structure. The side wall of the main support beam 3 is provided with an adjusting seat 10, which is a frame structure. The outer wall of the adjusting seat 10 is provided with inclined supports 5 for supporting two hangers 4, respectively. A monitoring mechanism is provided between the inclined support 5 and the adjusting seat 10 for detecting the force of the hanger 4. The monitoring mechanism: uses a mechanical sensor or a mechanical linkage to detect the force state of the inclined support 5, triggers a signal when the load of the hanger 4 is too large, and reminds the construction personnel. The main support beam 3 is provided with a positioning mechanism for driving the adjusting seat 10 to move along the extension direction of the main support beam 3. The positioning mechanism drives the adjusting seat 10 to slide on the main support beam 3 by mechanical or hydraulic drive, so as to change the relative position of the inclined support 5 and the hanger 4, thereby adjusting the stress point of the hanger 4 on the main support beam 3, and improving the carrying capacity of the hanger 4. The adjusting seat 10 is provided with a locking mechanism linked with the monitoring mechanism, which is used to fix the adjusting seat 10 on the outer side wall of the main support beam 3. The locking mechanism is linked with the monitoring mechanism, and the adjusting seat 10 is fixed by mechanical locking when the stress is abnormal to prevent displacement. The hanger body 7 is fixed to the top of the floor 1, and the main support beam 3 is arranged around the top wall thereof. One of the side walls of the main support beam 3 is provided with two vertical hangers 4, and the hydraulic lifting device 6 at the end of the hanger 4 is responsible for lifting the steel structure. The adjusting seat 10 moves along the main support beam 3 through the positioning mechanism, driving the hanger 4 to adjust the horizontal position; the inclined support 5 detects the force of the hanger 4 in real time through the monitoring mechanism, and when the force exceeds the limit, the locking mechanism triggers to fix the adjusting seat 10 on the main support beam 3, stopping the movement of the positioning mechanism. The horizontal movement of the hanger 4 is realized through the positioning mechanism, which meets the flexible demand of different lifting positions. The monitoring mechanism and the locking mechanism are linked to prevent displacement risk caused by overload and improve safety. The inclined support 5 and the adjusting seat 10 form a triangular support structure, which disperses the stress of the hanger 4 and reduces the deformation of the main support beam 3, thereby improving the safety of the structure during lifting.

[0031] In some technical solutions of the present invention, the monitoring mechanism includes two locking seats 11 installed on the outer wall of the adjustment seat 10. The locking seat 11 is a U-shaped structure. A locking groove is provided on the side wall of the locking seat 11. The diagonal support 5 is installed in the locking seat 11 through the load-bearing shaft 17. An adjusting wheel 16 connected to the diagonal support 5 is rotatably provided in the locking groove. The adjusting wheel 16 is installed on the outer wall of the load-bearing shaft 17. A mounting groove is provided in the locking groove along the extension direction of the main support beam 3. A monitoring member 19 is slidably provided in the mounting groove. Adjustment springs 18 are installed on both sides of the locking groove to abut against the monitoring member 19. The wheel surface of the adjusting wheel 16 abuts against the outer wall of the monitoring member 19. A displacement sensor is provided on the monitoring member. A first pressure sensor 24 is installed between the adjustment spring 18 and the locking groove. When the boom 4 is subjected to force, the diagonal support 5 transmits the force to the adjusting wheel 16. The adjusting wheel 16 rotates to press the monitoring member 19 to slide in the mounting groove, compressing the adjustment springs 18 on both sides. The displacement of monitoring element 19 is proportional to the force applied. By observing the displacement of monitoring element 19, the force applied to boom 4 is monitored. When the displacement of the monitoring element exceeds the limit, the locking mechanism is triggered, increasing the force applied to diagonal support 5. This force is converted into rotational motion by adjusting wheel 16. The wheel surface contacts monitoring element 19, pushing it to slide. Adjusting spring 18 provides reverse resistance, balancing the displacement of monitoring element 19 and forming a dynamic mechanical feedback mechanism. The use of mechanical contact and electronic sensors works together to reduce detection errors, making it suitable for high-vibration environments. The dual adjustment spring 18 design balances the positive and negative forces, preventing unilateral wear of monitoring element 19.

[0032] In some technical solutions of the present invention, the positioning mechanism includes a first telescopic structure 9 installed in the main support beam 3, the telescopic end of the first telescopic structure 9 is connected to the adjustment seat 10, and a guide mechanism for guiding the movement of the adjustment seat 10 is provided on the outer wall of the main support beam 3. The first telescopic structure 9 (such as a hydraulic cylinder) drives the adjustment seat 10 to move along the main support beam 3, and the guide mechanism (such as a guide rail or roller provided on the main support beam) ensures that the motion trajectory is straight. During operation, the position of the boom 4 is accurately adjusted by controlling the telescopic end stroke of the first telescopic structure 9. The guide mechanism avoids offset, improves the control accuracy of the hoisting position, and the mechanical guide reduces the load power of the telescopic structure.

[0033] In some technical schemes of the present application, the locking mechanism comprises a cam structure 20 mounted on the rotating shaft of the adjusting wheel 16, a locking rod 22 is arranged in the mounting groove, a positioning spring 23 is sleeved on the outer side wall of the locking rod 22, the positioning spring 23 is connected with the locking groove, a plurality of limiting holes 21 are equidistantly arranged on the outer side wall of the main supporting frame, and the locking rod 22 penetrates through the adjusting seat and is arranged in the limiting hole 21. The rotation of the adjusting wheel 16 drives the rotation of the cam structure 20, and the locking rod 22 is inserted into the limiting hole 21 of the main supporting beam 3 against the resistance of the positioning spring 23. When the monitoring mechanism detects overload, the cam quickly triggers the locking rod 22 to lock, and the quick-return characteristic of the cam profile is used to convert the rotary motion into a linear locking action of the locking rod 22. The cam structure 20 pushes the locking rod 22 into the limiting hole 21 to form mechanical locking, and the locking rod 22 and the limiting hole 21 form a rigid connection to prevent the adjusting seat 10 from sliding accidentally.

[0034] Preferably, two limiting blocks 25 are arranged in pairs on the outer side wall of the locking rod 22, and the limiting blocks 25 are wedge-shaped structures. The limiting blocks 25 can prevent the second pressure sensor 24 mounted on the end of the locking rod 22 from being mistakenly touched and triggering an alarm after the locking rod 22 is retracted in the mounting groove. After the locking rod 22 is pushed by the cam structure 20 to move in the direction of the limiting hole 21, the locking rod 22 can be limited in the corresponding limiting hole 21 by the limiting block 25, so that the locking rod 22 and the limiting hole 21 form a rigid connection to prevent the adjusting seat 10 from sliding accidentally. The monitoring effect of the present structure on the stress condition of the boom 4 is improved.

[0035] In some technical schemes of the present application, a plurality of adjusting teeth 27 are arranged around the outer side wall of the adjusting wheel 16, a plurality of limiting teeth 26 are equidistantly arranged on the outer side wall of the monitoring member, and a part of one adjusting tooth 27 is embedded between any two adjacent limiting teeth 26. The adjusting teeth 27 and the limiting teeth 26 are engaged, the limiting teeth 26 are clamped into the gap between the adjacent adjusting teeth 27 every time the adjusting wheel 16 rotates by a certain angle, forming a step-by-step mechanical locking, ensuring that the displacement of the monitoring member 19 and the load are in a linear relationship, discretizing the continuous rotation through the engagement between the teeth, improving the monitoring resolution, avoiding the slippage of the adjusting wheel 16 and the monitoring member 19 through the engagement of the teeth, avoiding the misjudgment of the stress condition of the boom 4, and improving the detection reliability. The step-by-step displacement facilitates the quantitative analysis of the load state.

[0036] In some technical solutions of the present invention, an adjusting beam 8 is slidingly provided on the side wall of the boom 4. The adjusting beam 8 is a "匚"-shaped steel structure. A driving structure for driving the adjusting beam 8 to reciprocate is provided in the boom 4, and a supporting structure for supporting the adjusting beam 8 is provided on the diagonal support 5. The driving structure in the boom 4 pushes the adjusting beam 8 to extend and retract, and adjusts the extension length of the hydraulic lifting device 6. The diagonal support 5 dynamically adapts to the position change of the adjusting beam 8 through the supporting structure (such as a hydraulic telescopic rod), so that the adjusting beam 8 extends the effective length of the boom 4 to meet the needs of large-span hoisting. In addition, the adjusting beam 8 realizes stepless adjustment of the length of the boom 4 to cover a wider hoisting area. The supporting structure and the adjusting beam 8 are linked to avoid structural instability caused by excessive cantilever length.

[0037] In some technical solutions of the present invention, the drive structure includes a second telescopic structure 15 installed in the boom 4. The telescopic end of the second telescopic structure 15 is connected to the adjustment beam 8, and the hydraulic lifting device is installed on the free end of the adjustment beam 8. The second telescopic structure 15 (such as an electric push rod) directly drives the adjustment beam 8 to move. The hydraulic lifting device 6 extends and retracts synchronously with the end of the adjustment beam 8 to achieve coordinated adjustment of the lifting height and horizontal position. The independent drive unit enables multi-directional fine-tuning to meet the requirements of complex lifting paths.

[0038] In some technical solutions of the present invention, a third telescopic structure 14 connected to the diagonal support 5 is mounted on the outer wall of the main support beam 3. A guide groove is defined on the outer wall of the boom 4, within which a support seat 28 connected to the diagonal support 5 slides. The third telescopic structure 14 pushes the diagonal support 5 along the guide groove of the boom 4. The support seat 28 cooperates with the guide groove to ensure that the diagonal support 5 always maintains the optimal support angle with the adjustment beam 8, eliminating the need for manual adjustment of the diagonal support 5 angle and improving operational efficiency.

[0039] In some technical solutions of the present invention, the support structure includes an outer support frame 13 installed on the outer side wall of the diagonal support 5, and a fourth telescopic structure 12 connected to the diagonal support 5 is installed on the side wall of the outer support frame 13. The fourth telescopic structure 12 drives the outer support frame 13 to retract and expand the contact area of ​​the diagonal support 5. When hoisting heavy components, the outer support frame 13 is unfolded to enhance the local load-bearing capacity. By increasing the support area, the pressure is dispersed to prevent the local structure from collapsing. The outer support frame 13 provides an additional fulcrum, which significantly increases the upper limit of the single hoisting weight. The telescopic outer support is easy to store, reducing the space occupied in the non-operating state.

[0040] Preferably, the outer support frame 13 is slidably arranged on the outer side wall of the oblique support 5 through the frame body, and the outer support frame 13 is parallel to the oblique support 5. When the outer support frame 13 is extended and retracted under the push of the fourth telescopic structure 12, a part of the outer support frame 13 passes through the boom 4 and is placed in the adjusting beam 8, supporting the adjusting beam 8 while locking it.

[0042] The main supporting beam 3 is fixed around the top of the hanger body 7, and then the hanger body 7 is fixed to the top of the floor 1;

[0043] The adjusting seat 10 is moved to the initial position along the main supporting beam 3 through the positioning mechanism;

[0044] The inclined support 5 is installed on the outer wall of the adjusting seat 10, and the position of the inclined support 5 in the guide groove of the boom 4 is adjusted through the third telescopic structure 14;

[0045] The second telescopic structure 15 in the boom 4 is started, the adjusting beam 8 is driven to be telescoped outward, the effective length of the boom 4 is expanded to the target range, and the telescoping amount of the outer support frame 13 is adjusted synchronously to ensure that it is partially embedded in the adjusting beam 8;

[0046] The hydraulic lifting device 6 is operated in an empty state, and the monitoring mechanism is observed;

[0047] Whether the engagement state of the adjusting wheel 16 and the monitoring piece 19 is normal, and whether the signals of the displacement sensor and the pressure sensor 24 are sensitive;

[0048] The light test component is hoisted, the monitoring mechanism is observed, if the stress of the boom 4 exceeds the limit, the adjusting wheel 16 presses the monitoring piece 19 to slide, the locking mechanism is triggered, and the positioning mechanism is immediately stopped.

[0049] The load state is quantified through the displacement sensor data, and it is ensured that the hoisting path meets the design requirements;

[0050] According to the weight and size of the component, the length and horizontal position of the boom 4 are adjusted, the inclined support 5 and the outer support frame 13 are real-time adapted to the position of the adjusting beam 8, the load pressure is dispersed, the hydraulic lifting device 6 slowly lifts the component, the monitoring mechanism tracks the stress state throughout the process, the locking mechanism is kept on standby, and the hoisting is completed.

[0051] The above is only a preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations.
