Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a hydraulic driving overturning installation mechanism for a giant steel column. BACKGROUND

[0002] The existing building is often located in the core area of the city or the dense factory area, and there are often existing building groups, underground pipelines and overhead lines around. Large truck cranes and caterpillar cranes cannot enter the site. Moreover, the indoor space of the existing building is narrow, and the crane boom cannot be unfolded. The ground of some old buildings is a prefabricated floor or a plain foundation, and the bearing capacity is only 0.1-0.3MPa, which cannot bear the weight of the crane (the conventional 25-ton crane ground pressure ratio is greater than or equal to 0.5MPa), and is easy to cause ground cracking or structure collapse.

[0003] At present, in the steel structure engineering of the existing building, the overturning installation of the steel column under the condition of no crane mainly adopts the following technical scheme:

[0004] Scheme one: manual prying + temporary support overturning.

[0005] First, a steel pipe temporary support (height 2-3m) is built around the installation position, and the steel column transported to the site horizontally (transported by a handcart or a hydraulic cattle) is placed on the support. Three to five operators use a crowbar and a jack (10-20 tons of manual jack) to first lift one end of the steel column, pad with a wooden board to adjust the height, and then pry the other end to rotate around the support fulcrum. The steel column is gradually overturned to the vertical state. After overturning, the position is adjusted by a hand-operated hoist on the support, and the installation node of the existing structure is connected.

[0006] Scheme two: winch + pulley block traction overturning.

[0007] A hoisting point is embedded in the beam or roof of the existing building (the existing beam needs to be reinforced, such as pasting carbon fiber cloth), a small winch (rated tension ≤5 tons) and a fixed pulley block are installed, the steel column is placed horizontally on the ground guide rail, the upper part of the steel column is bound with a steel wire rope, the winch is used to pull the steel wire rope, and the steel column is overturned to the vertical state around the bottom fulcrum (a steel plate is laid to reduce friction). Two people need to stabilize the steel column with a rope on both sides during the overturning process to prevent the steel column from colliding with the existing wall.

[0008] The existing scheme has low construction efficiency, great safety hazards, and poor adaptability to different construction scenes, and may collide and damage the existing building structure during construction. Therefore, it is necessary to provide a hydraulic driving overturning installation mechanism for a giant steel column, which can solve the above technical problems of the prior art. SUMMARY

[0009] The purpose of the present application is to provide a hydraulic driving overturning installation mechanism for a giant steel column, which can solve the above technical problems of the prior art.

[0010] To achieve the above object, the technical scheme of the present application is:

[0011] A hydraulic driving overturning installation mechanism for a giant steel column, comprising: a fixed frame, a guide plate, an overturning frame and an overturning driving assembly; the fixed frame is fixedly installed at an installation position of the giant steel column, the guide plate is installed on the fixed frame, one end of the overturning frame is movably connected with the guide plate, and one end of the giant steel column is horizontally arranged on the upper surface of the overturning frame; the overturning driving assembly is supported on the lower surface of the overturning frame and can push the overturning frame to overturn upward, so that the overturning frame drives the giant steel column to overturn from a horizontal position to a vertical position.

[0012] The fixed frame is located in the overturning vertical plane of the giant steel column, and the fixed frame comprises side frames, a front frame and a rear frame; a pair of side frames are symmetrically installed on the ground at both sides of the installation position of the giant steel column, and the front frame and the rear frame are installed on the ground in front of and behind the installation position of the giant steel column respectively and are connected with the pair of side frames.

[0013] A pair of guide plates are fixedly installed on the pair of side frames, and the overturning frame is movably arranged between the two guide plates through two groups of overturning driving assemblies arranged side by side.

[0014] Each group of overturning driving assemblies comprises a hydraulic oil cylinder, a first connecting rod and a second connecting rod; the fixed end of the hydraulic oil cylinder is installed on the front frame, and the top end of the hydraulic oil cylinder, one end of the first connecting rod and one end of the second connecting rod are hinged; the other end of the first connecting rod is hinged to a connecting rod connecting seat in the middle of the side end of the overturning frame, and the other end of the second connecting rod is hinged to the bottom of the side frame.

[0015] Each guide plate is formed with an axis hole and a guide limiting slot; both side ends of the overturning frame are provided with a positioning pin, and the positioning pin is slidably arranged in the guide limiting slot; both sides of the overturning frame are provided with an axis pin, and the axis pin is rotatably arranged in the axis hole.

[0016] The guide limiting slot is in the shape of a quarter of a circle, and the axis hole is located at the center of the quarter of a circle.

[0017] The bottom of the axis hole is formed with a first recess, so that the axis pin can fall into the first recess; the bottom of the guide limiting slot is formed with a second recess, so that the positioning pin can fall into the second recess.

[0018] The first recess and the second recess are both vertical grooves, and the height of the first recess is the same as the height of the second recess.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1. The application can eliminate the hidden danger of manual operation: compared with the existing "manual prying + temporary support" scheme, the application realizes automatic overturning by pushing the overturning frame through the overturning drive assembly, without direct contact with the overturning parts throughout the process, combined with the mechanical locking of the falling of the shaft pin into the first sink and the falling of the positioning pin into the second sink, which can greatly reduce the safety accident rate during overturning and avoid collision and falling accidents caused by support point sliding and large steel column shaking.

[0021] 2. The application can be designed in a modular way, with small size, and can be transported through existing building stairs and elevators, requiring only 1-2 people to assemble on site, which can reduce labor costs by more than 60% compared with traditional 3-5 people synchronous operation; the installation process of the whole mechanism takes ≤1 hour, which is more efficient than the traditional 3-4 hour construction of temporary support, without the need to rent large cranes, customize tooling, and change tooling for different specifications of steel columns, and when multiple specifications of steel columns are installed continuously, there is no need to interrupt and adjust, further improving the continuity of operation, reducing equipment investment costs by 40%-50%, and being well adapted to narrow installation environments, especially meeting the needs of "strict cost control" in existing building renovation projects.

[0022] 3. The application is designed for the particularity of the existing building without crane operation scene, through modular structure design, precise overturning control and scene adaptation optimization, effectively solving the technical problems of high safety risk, low efficiency, poor adaptability, damage to existing structure and insufficient positioning accuracy in the prior art, providing a standardized and replicable installation solution for existing building steel structure renovation projects, and having significant industry application value and promotion prospects.

DETAILED DESCRIPTION

[0036] The hydraulic driving overturning installation mechanism of the giant steel column of the application is further described in detail below in combination with the drawings and specific embodiments. The advantages and features of the application will be more apparent according to the following description and claims. It should be noted that the drawings are all very simplified and use non-precise proportions, only for the purpose of facilitating and clarifying the purpose of assisting in the description of the embodiments of the application.

[0037] Please refer to the drawings Figure 1 , the drawings Figure 6 to the drawings Figure 8 and the drawings Figure 11A hydraulic drive overturning installation mechanism for a giant steel column, comprising a fixed frame, a guide plate 2, an overturning frame 3 and an overturning drive assembly; the fixed frame is fixedly installed at the installation position of the giant steel column 4, the guide plate 2 is installed on the fixed frame, one end of the overturning frame 3 is movably connected with the guide plate 2, and one end of the giant steel column 4 is horizontally arranged on the upper surface of the overturning frame 3; the overturning drive assembly is supported on the lower surface of the overturning frame 3 and can push the overturning frame 3 to overturn upward, so that the overturning frame 3 drives the giant steel column 4 to overturn from a horizontal position to a vertical position.

[0038] Preferably, the overturning frame 3 can be made of steel by welding, and the specification, shape and size of the steel can be adaptively selected according to the size and weight of the giant steel column 4 to be installed, so as to ensure the stable support of one end of the giant steel column 4. The giant steel column 4 is temporarily fixed and connected to the overturning frame 3, so that the giant steel column 4 overturns synchronously with the overturning frame 3.

[0039] The overturning drive assembly is used to provide overturning driving force, and the guide plate 2 is used to provide guidance and limiting for the overturning of the overturning frame 3, so that the overturning frame 3 drives the giant steel column 4 to overturn from a horizontal position to a vertical position, so that the bolt holes of the giant steel column 4 are aligned with the foundation bolts on the ground, which is beneficial to improve the construction efficiency, construction safety, construction precision and quality.

[0040] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 6 to the accompanying drawings Figure 11 , the fixed frame is located in the overturning vertical plane of the giant steel column 4, and the fixed frame comprises side frames 11, a front frame 12 and a rear frame 13; a pair of side frames 11 are symmetrically installed on the ground on both sides of the installation position of the giant steel column 4, and the front frame 12 and the rear frame 13 are respectively installed on the ground in front of and behind the installation position of the giant steel column 4 and are connected with the pair of side frames 11.

[0041] Preferably, the side frames 11, the front frame 12 and the rear frame 13 can be made of steel by welding, and the specification, shape and size of the steel can be adaptively selected according to the size and weight of the giant steel column 4 to be installed, so as to ensure that the fixed frame has sufficient bearing capacity and will not be deformed or displaced during the overturning of the giant steel column 4.

[0042] The front end and the rear end of the pair of side frames 11 are connected by the front frame 12 and the rear frame 13 respectively to form a whole fixed frame, which has high structural strength and strong bearing capacity. The front frame 12 and the rear frame 13 are the same in structure but different in installation direction, and through the cooperative action of the front frame 12 and the rear frame 13, the structural stability of the whole fixed frame is ensured, and the risk of overturning is effectively avoided.

[0043] Please refer to the accompanying drawings Figure 1The pair of side frames 11 are each fixedly provided with a guide plate 2, and the turnover frame 3 is rotatably arranged between the two guide plates 2 through two groups of turnover driving assemblies arranged side by side.

[0044] The two guide plates 2 guide and limit the turnover process of the turnover frame 3 on both sides of the turnover frame 3, and the stress on both sides is uniform and balanced, thereby ensuring the stability, controllability and safety of the turnover of the turnover frame 3 and the giant steel column 4.

[0045] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 6 to the accompanying drawings Figure 8 , each group of the turnover driving assembly comprises a hydraulic oil cylinder 5, a first connecting rod 6 and a second connecting rod 7; the fixed end of the hydraulic oil cylinder 5 is installed on the front frame 12, and the top end of the hydraulic oil cylinder 5, one end of the first connecting rod 6 and one end of the second connecting rod 7 are hingedly connected; the other end of the first connecting rod 6 is hingedly connected to the connecting rod connecting seat 31 at the middle of the side end of the turnover frame 3, and the other end of the second connecting rod 7 is hingedly connected to the bottom of the side frame 11 on the same side.

[0046] The driving force of the hydraulic oil cylinder 5 is determined according to the actual tonnage of the giant steel column 4 to be installed, and the top end of the hydraulic oil cylinder 5, the length of the first connecting rod 6 and the length of the second connecting rod 7 can be adaptively adjusted according to the actual turnover requirement, so as to ensure that the turnover frame 3 can be turned between the horizontal position (0°) and the vertical position (90°).

[0047] Under the pushing of the top end of the hydraulic oil cylinder 5, the included angle between the first connecting rod 6 and the second connecting rod 7 increases, so that the first connecting rod 6 pushes the turnover frame 3 upward to realize the upward turnover of the turnover frame 3.

[0048] Please refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 3 , each of the guide plates 2 is formed with a rotating shaft hole 21 and a guide limiting groove 22; the two side ends of the turnover frame 3 are each provided with a positioning pin 32, and the positioning pin 32 is slidably arranged in the guide limiting groove 22; the two sides of the turnover frame 3 are each provided with a rotating shaft pin 33, and the rotating shaft pin 33 is rotatably arranged in the rotating shaft hole 21.

[0049] The rotating shaft hole 21 is used for penetrating the rotating shaft pin 33, and the diameter of the rotating shaft hole 21 is slightly larger than the diameter of the rotating shaft pin 33, so that the rotating shaft pin 33 can rotate in the rotating shaft hole 21, and the turnover frame 3 can be turned around the rotating shaft pin 33.

[0050] The guide limiting groove 22 is used for penetrating the positioning pin 32, and the width of the guide limiting groove 22 is slightly larger than the diameter of the positioning pin 32. In the process of the turnover of the turnover frame 3, the positioning pin 32 slides from one end to the other end of the guide limiting groove 22, which can guide and limit the turnover track of the turnover frame 3, thereby ensuring the stability and controllability of the turnover process.

[0051] Please see the attached Figure 3 The guide limiting groove 22 is in the shape of a quarter of a circle, and the rotating shaft hole 21 is located at the center of the quarter of the circle to realize the 90° overturning of the overturning frame 3 from the horizontal position to the vertical position.

[0052] Please see the attached Figure 3 The bottom of the rotating shaft hole 21 is formed with a first sunken groove 23, so that the rotating shaft pin 33 can fall into the first sunken groove 23; and the bottom of the guide limiting groove 22 is formed with a second sunken groove 24, so that the positioning pin 32 can fall into the second sunken groove 24.

[0053] Through the setting of the first sunken groove 23 and the second sunken groove 24, the overturning frame 3 and the giant steel column 4 can fall as a whole by a certain height, so as to limit the overturning of the overturning frame 3 by the clamping of the rotating shaft pin 33 in the first sunken groove 23 and the clamping of the positioning pin 32 in the second sunken groove 24, thereby ensuring that the giant steel column 4 is in the vertical position during the installation process.

[0054] Preferably, the upper and lower surfaces of the rotating shaft pin 33 are flat, and the left and right surfaces are circular arc surfaces, and the spacing between the upper and lower surfaces of the rotating shaft pin 33 matches the width of the first sunken groove 23, so as to ensure the limiting effect of the first sunken groove 23 on the rotating shaft pin 33. Similarly, the size of the positioning pin 32 matches the width of the second sunken groove 24.

[0055] Please see the attached Figure 3 The first sunken groove 23 and the second sunken groove 24 are both vertical groove bodies, and the height of the first sunken groove 23 is the same as the height of the second sunken groove 24, so as to ensure the sinking synchronization of the positioning pin 32 and the rotating shaft pin 33.

[0056] Please see the attached Figure 4 A construction method of the hydraulic drive overturning and installing mechanism of the giant steel column, comprising the following steps:

[0057] Please see the attached Figure 5 Step 1: Fixing and installing the hydraulic drive overturning and installing mechanism of the giant steel column at the ground surface at the installation position of the giant steel column 4, and installing one end of the giant steel column 4 to the overturning frame 3. At this time, the giant steel column 4 is in a horizontal state (0°).

[0058] Step 2: Overturning preparation.

[0059] Before the overturning operation, it is necessary to check the firmness of the installation of each part of the hydraulic drive overturning and installing mechanism of the giant steel column, so as to ensure the safety and controllability during the overturning process.

[0060] Please see the attached Figure 6Step 3: Push the turnover frame 3 upward to turn over by the turnover driving assembly, so as to turn over the giant steel column 4 by a safe angle.

[0061] Preferably, the safe angle is 5°, and the specific angle value of the safe angle can also be adaptively adjusted according to the actual construction conditions.

[0062] The step 3 includes the following sub-steps:

[0063] Step 31: A pair of turnover driving assemblies are started at the same time, so that the top end of the hydraulic cylinder 5 is extended.

[0064] Step 32: The top end of the hydraulic cylinder 5 pushes one end of the first connecting rod 6 and one end of the second connecting rod 7, so that the first connecting rod 6 pushes the turnover frame 3 upward.

[0065] Step 33: The turnover frame 3 is turned upward by a safe angle relative to the guide plate 2 through the pivot pin 33 and the pivot hole 21, and drives the giant steel column 4 to be turned upward synchronously.

[0066] At this time, the turnover frame 3 and the giant steel column 4 are in an inclined state (safe angle).

[0067] Please refer to the attached Figure 7 Step 4: Continue to push the turnover frame 3 upward to turn over by the turnover driving assembly, so as to turn over the giant steel column 4 to 90°, that is, to the vertical state.

[0068] During the process of turning over the giant steel column 4 by a safe angle and the standing process after turning over, it is confirmed that the parts of the hydraulic driving turnover installation mechanism of the giant steel column do not appear deformation, connection loosening, loosening and sliding of the giant steel column 4, etc. The turning over can be continued, that is, step 4 is executed.

[0069] The turning over process of step 4 is the same as that of step 3, only the turning over angle is different, which will not be described here.

[0070] Please refer to the attached Figure 8 Step 5: The turnover frame 3 is limited in position.

[0071] The step 5 includes the following sub-steps:

[0072] Step 51: The turnover frame 3 is slowly turned to the vertical state with the pivot pin 33 as the shaft.

[0073] Step 5 is the formal turning over process of the giant steel column 4, and the turning over speed should not be too fast, the control acceleration should be less than 0.15g (g is the acceleration of gravity), and the uniform speed should be maintained for the whole process and the time should be not less than 10 minutes.

[0074] Step 52: the positioning pin 32 slides to the lower end of the guide limiting slot 22 along with the turning of the turning frame 3, the top end of the hydraulic cylinder 5 is slowly retracted, the bolt hole on the mega steel column 4 is accurately aligned with the anchor bolt at the installation position.

[0075] Step 53: under the gravity of the mega steel column 4, the positioning pin 32 falls into the second sink groove 24, the shaft pin 33 falls into the first sink groove 23 at the same time, and the mega steel column 4 is located at the installation position.

[0076] Preferably, the falling height of the positioning pin 32 and the shaft pin 33 is 10 cm, the turning of the turning frame 3 is limited by the positioning pin 32 and the shaft pin 33 of the vertical slot body, which plays a locking role, thereby ensuring the stability and safety of the installation process of the mega steel column 4.

[0077] Through the slow retraction of the top end of the hydraulic cylinder 5, the slow and safe falling of the turning frame 3 and the mega steel column 4 is ensured.

[0078] Step 6: fix the anchor bolt of the mega steel column 4, and complete the installation of the mega steel column 4.

[0079] The mega steel column 4 is installed and fixed by conventional process, which is not described here.

[0080] Step 7: remove or disassemble the hydraulic drive turning installation mechanism of the mega steel column by releasing the connection between the mega steel column 4 and the turning frame 3.

[0081] The above description is only a description of the preferred embodiment of the present application, and does not limit the scope of the present application, any modification of the above disclosure made by a person skilled in the art belongs to the protection scope of the claims.
