Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a steel structure installation auxiliary device used in building construction. Background Art

[0002] During the construction process, when installing steel structures, sometimes part of the installed structure will be tilted. In order to facilitate the subsequent docking and installation of the steel structure, a motor is usually used to rotate the steel structure to be installed so that its connection surface matches the existing tilted structure to ensure that the two can be docked smoothly. Since the motor output shaft must always maintain a fixed connection with the steel structure connection block, this makes the role of the motor redundant and unnecessary when the hoisting device performs hoisting tasks in a non-tilted state. Secondly, in all hoisting operations, once the steel structure leaves the ground, factors such as wind may cause the steel structure to shake, thereby causing the splint to rotate. Since the splint is fixed to the motor output shaft, this shaking will exert additional force on the motor output shaft, causing the motor to wear faster and increase the cost of maintenance and servicing. Summary of the invention

[0003] In order to overcome the shortcomings of existing steel structure lifting equipment in non-tilted lifting tasks, in which the fixed connection between the motor and the steel structure connecting block becomes unnecessary and increases equipment wear and maintenance costs, and at the same time, the shaking caused by wind transmits additional stress through the fixed motor output shaft, accelerating motor damage, the present invention provides a steel structure installation assistant for construction.

[0004] The technical solution is: a steel structure installation assistant for construction, including a base plate, a connecting plate and a hook; the base plate is rotatably connected to the connecting plate; the connecting plate is fixedly connected to the hook; it also includes a sliding block, a screw, a rotating ring, a steel wire rope, a limit block and a fixed component; the connecting plate is slidably connected to the sliding block; the sliding block is rotatably connected to two screws; all the screws are screwed together with the connecting plate; each screw is fixedly connected to a rotating ring; at least four steel wire ropes are fixedly connected to the base plate; all the steel wire ropes are fixedly connected to the sliding block; the sliding block is fixedly connected to the limit block; the base plate is connected to a fixed component for fixing the steel structure.

[0005] More preferably, a silicone sleeve is provided on the outer side of the rotating ring.

[0006] More preferably, the fixing assembly includes an electric push rod 1, a sliding plate, a screw rope, a fixing plate, a locking plate, an electric push rod 2, an electric push rod 3 and a push rope plate; an electric push rod 1 is fixedly connected to each of the two sides of the front of the base plate; the telescopic parts of all the electric push rods 1 are commonly fixed to the sliding plate; the sliding plate is fixedly connected to at least five screw ropes; the other ends of all the screw ropes are commonly fixedly connected to the fixing plate; an electric push rod 2 is fixedly connected to each of the two sides of the rear of the base plate; the telescopic parts of all the electric push rods 2 are commonly fixedly connected to the locking plate; the locking plate is provided with a plurality of grooves 1; the fixing plate is placed on the locking plate, and the screw rope passes through the groove 1, and two electric push rods 3 distributed on the left and right are fixedly connected to the front side of the base plate; the telescopic parts of the two electric push rods 3 are commonly fixedly connected to the push rope plate; the push rope plate is provided with a plurality of grooves 2; the screw rope passes through the groove 2.

[0007] More preferably, a sliding groove is provided on the bottom plate, the sliding plate is located in the sliding groove of the bottom plate, and the sliding plate is slidably connected to the sliding groove.

[0008] More preferably, it further comprises a safety rope; at least two safety ropes are fixedly connected to the bottom plate and the sliding block, and the length of the safety rope is greater than that of the steel wire rope.

[0009] More preferably, the steel wire rope is connected to the base plate and the sliding block respectively by bolts.

[0010] More preferably, it further includes a material stopper; and at least two material stoppers are connected to the left portion of the bottom plate.

[0011] More preferably, each stopper block is provided with a guide portion.

[0012] More preferably, the stop block is connected to the base plate by bolts.

[0013] More preferably, the lower side of the bottom plate is rough, and the facing sides of the positioning plate and the rope pushing plate are rough.

[0014] The beneficial effects are:

[0015] The lowering of the limit block can lock the rotation of the base plate. Compared with the method of using a motor, it can effectively avoid damage to the motor output shaft. The lifting angle is adjusted by controlling the lifting of the sliding block with a high-strength alloy screw. Similar to the method of using an electric telescopic rod, it can also avoid damage to the output shaft of the electric telescopic rod, thereby reducing maintenance costs.

[0016] The sliding block drives the wire rope to move to adjust the inclination angle of the base plate. After the steel structure to be installed is fixed by the base plate, the hoisting inclination angle of the steel structure to be installed is consistent with the inclination angle required for its installation. It is then hoisted to the installation position. There is also no need to perform a secondary adjustment on the inclination angle of the steel structure to be installed at a high altitude, which eliminates safety hazards and speeds up installation efficiency.

[0017] The screw rod is screwed to the connecting plate. If the steel structure to be installed pulls the sliding block downward, there is a tendency to pull the screw rod downward relative to the connecting plate. The downward movement of the screw rod relative to the connecting plate will make the thread fit between the screw rod and the connecting plate tighter, thereby improving the lifting stability.

[0018] The lower end of the blocking block is pressed against the left side of the steel frame of the steel structure to be installed to prevent it from sliding further to the left, thereby avoiding the safety accident of the steel structure to be installed slipping and falling.

[0019] The guide portion becomes a supporting point, which enhances the stability when installing the steel structure to be installed and avoids the problem of shaking or sliding of the steel structure to be installed during the installation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A silicone sleeve is provided on the outside of the rotating ring 5 to prevent the worker from slipping when twisting the rotating ring 5 .

[0035] The fixing assembly includes an electric push rod 101, a sliding plate 102, a screw rope 103, a fixing plate 104, a positioning plate 105, an electric push rod 2 106, an electric push rod 3 107 and a push rope plate 108; an electric push rod 101 is fixedly connected to the left and right sides of the front of the bottom plate 1; the telescopic parts of all the electric push rods 101 are fixedly connected to the sliding plate 102; the sliding plate 102 is fixedly connected to five screw ropes 103; the other ends of all the screw ropes 103 are fixedly connected to the fixing plate 104; the left and right sides of the rear of the bottom plate 1 are fixedly connected to the There is an electric push rod 2 106; the telescopic parts of all the electric push rods 2 106 are commonly fixedly connected to a positioning plate 105; the positioning plate 105 is provided with at least five grooves 10501; the fixing plate 104 is placed on the positioning plate 105, and the screw rope 103 passes through the groove 10501, and two electric push rods 3 107 distributed on the left and right are fixedly connected to the front side of the bottom plate 1; the telescopic parts of the two electric push rods 3 107 are commonly fixedly connected to a push rope plate 108; the push rope plate 108 is provided with five grooves 2 10801; the screw rope 103 passes through the groove 2 10801.

[0036] A sliding groove is provided on the base plate 1, and the sliding plate 102 is located in the sliding groove of the base plate 1, and the sliding plate 102 is slidably connected to the sliding groove. When hoisting, the hoisted object pulls the screw rope 103 downward, thereby applying a downward pulling force to the sliding plate 102, and the sliding groove of the base plate 1 provides support for the lower side of the sliding plate 102, sharing the pressure at the connection between the electric push rod 101 and the sliding plate 102, thereby improving the stability of the operation of the electric push rod 101.

[0037] It also includes a safety rope 8; the bottom plate 1 and the sliding block 3 are fixedly connected to two safety ropes 8, and the length of the safety rope 8 is greater than the wire rope 6.

[0038] The steel wire rope 6 is respectively connected to the bottom plate 1 and the sliding block 3 by bolts. When the steel wire rope 6 is worn, it is convenient to replace the steel wire rope 6.

[0039] The specific working steps are:

[0040] When it is necessary to install the steel structure 100 to be installed in an inclined state, the external crane drives the connecting plate 2 and the bottom plate 1 to move to the top of the steel structure 100 to be installed through the hook 9, and then the worker holds the fixing plate 104, drives the fixing plate 104 to move upward and then moves backward away from the bottom plate 1, so that the fixing plate 104 drives the screw rope 103 to disengage from the positioning plate 105, and then holds the fixing plate 104 to move under the sliding plate 102, and then the external crane drives the bottom plate 1 to descend and fits the upper part of the steel structure 100 to be installed, the worker holds the fixing plate 104 and passes through the bottom of the steel structure 100 to be installed, and repositions the fixing plate 104 on the positioning plate 105, limits the fixing plate 104 by the positioning plate 105, and then limits the rear end of the screw rope 103, and the screw rope 103 will pass through the groove 10501, as shown in FIG. Figure 7In the state shown, in order to ensure that the screw rope 103 firmly fixes the steel structure 100 to be installed, after the fixing plate 104 is placed on the positioning plate 105, the electric push rod 106 is controlled to push the positioning plate 105 to move in the direction of the steel structure 100 to be installed, and the electric push rod 107 is controlled to push the rope pushing plate 108 to move in the direction of the steel structure 100 to be installed. Since the screw rope 103 passes through the groove 10801, the rope pushing plate 108 will squeeze the screw rope 103 when moving, so that the screw rope 103 is squeezed to gradually fit with the lower side of the bottom plate 1, and the contact part of the screw rope 103 with the steel structure 100 to be installed is pushed to move, and the positioning The plate 105 will also drive one end of the screw rope 103 to move toward the direction of the steel structure 100 to be installed, so that the screw rope 103 moves and contacts the front and rear sides of the steel structure 100 to be installed. At the same time, the electric push rod 101 will drive the front end of the screw rope 103 to move away from the steel structure 100 to be installed through the sliding plate 102, so that the screw rope 103 drives the steel structure 100 to be installed to rise and contact the lower side of the bottom plate 1, so as to achieve the steel structure 100 to be installed The screw rope 103 is fastened to the middle position of the lower side of the bottom plate 1, thereby ensuring that the steel structure 100 to be installed cannot move during the hoisting process, thereby ensuring the safety of the construction;Then the external crane lifts the steel structure 100 to be installed and moves the steel structure 100 to be installed to the installation position. Since the connecting plate 2 is rotatably connected to the bottom plate 1, after the steel structure 100 to be installed is lifted, when the lifting weights on the left and right sides of the bottom plate 1 are different, the bottom plate 1 will rotate, thereby driving the steel structure 100 to be installed to rotate. If the steel structure 100 to be installed needs to be installed in an inclined state with the left side higher and the right side lower, the bottom plate 1 is fixed at the left half of the steel structure 100 to be installed using the screw rope 103 when lifting the steel structure 100 to be installed, and the bottom plate 1 is lifted. When installing the steel structure 100 to be installed, since the steel structure 100 to be installed on the right side of the bottom plate 1 is heavier, the steel structure 100 to be installed drives the bottom plate 1 to rotate, so that the bottom plate 1 and the steel structure 100 to be installed are in a state where the left side is higher and the right side is lower. If the steel structure 100 to be installed needs to be installed in a state where the left side is lower and the right side is higher, the screw rope 103 can be used to fix it at the right half of the steel structure 100 to be installed. At this time, the steel structure 100 to be installed is hoisted to the installation position in an inclined state, which is convenient for workers to perform installation work. After the steel structure 100 to be installed is fixed, the greater the gravity difference between the left and right ends, the easier it is to install. , the greater the inclination of the steel structure 100 to be installed, the greater the inclination of the steel structure 100 to be installed. Then, by changing the fixed position of the steel structure 100 to be installed, the inclined hoisting state of the steel structure 100 to be installed can be more in line with the inclination angle required during installation. When it is necessary to hoist the steel structure 100 to be installed in a horizontal installation state, the worker holds the rotating ring 5 and twists the screw 4. Since the screw 4 is screwed to the connecting plate 2, the screw 4 can be rotated to rise and fall on the connecting plate 2. At this time, the rotation of the screw 4 drives the sliding block 3 to descend, so that the sliding block 3 drives the limit block 7 to descend and press the rotating part of the bottom plate 1. At this time, the bottom plate 1 will be blocked by the limit block 7 when rotating, so when the horizontally installed steel structure 100 needs to be installed, the base plate 1 cannot rotate, which is suitable for different lifting situations. The limit block 7 is lowered to lock the rotation of the base plate 1. Compared with the method of using a motor, it can effectively avoid the damage of the motor output shaft. The method of adjusting the lifting angle by controlling the lifting of the sliding block 3 by using a high-strength alloy screw 4 is similar to the method of using an electric telescopic rod, which can also avoid the damage of the output shaft of the electric telescopic rod and reduce maintenance costs. ;

[0041] Considering that the lifting tilt angle of the steel structure 100 to be installed is adjusted by adjusting the fixed position of the steel structure 100 to be installed, there is a deviation between the actual lifting tilt angle and the required installation tilt angle, resulting in the need for workers to lift or press down the steel structure 100 to be installed to adjust the tilt angle during installation, which affects the installation efficiency. In addition, there are additional safety hazards in adjusting the lifting angle of the steel structure 100 to be installed at a high place. Therefore, before lifting, the worker twists the rotating ring 5 to drive the screw 4 to rotate, and the rotation of the screw 4 can be adjusted on the connecting plate 2 rises or falls, and the rotation of the screw rod 4 will drive the sliding block 3 to rise or fall. The rise or fall of the sliding block 3 will pull the right part of the bottom plate 1 to rise synchronously through the wire rope 6. If the installation inclination angle of the steel structure 100 to be installed is a state of left low and right high, the specific installation inclination angle is measured in advance or calculated according to the installation drawing. Before hoisting the steel structure 100 to be installed, the sliding block 3 is controlled to rise, and the sliding block 3 will pull the wire rope 6 to rise. At this time, the wire rope 6 will pull the right part of the bottom plate 1 to rise, so that the bottom plate 1 is in an inclined state of left low and right high, and the bottom plate 1 is tilted. The inclination angle of the plate 1 is measured, and the position of the sliding block 3 is fine-tuned by twisting the rotating ring 5 according to the measurement result, and then the inclination angle of the bottom plate 1 is fine-tuned by pulling the wire rope 6 until the inclination angle of the bottom plate 1 is consistent with the installation inclination angle of the steel structure 100 to be installed, and then the steel structure 100 to be installed is fixed on the lower side of the bottom plate 1, and is fixed at the left half of the steel structure 100 to be installed by the screw rope 103, so that the lifting center of gravity of the steel structure 100 to be installed is located on the right part of the bottom plate 1, and the steel structure to be installed is fixed on the lower side of the bottom plate 1. After the steel structure 100 is hoisted, under the action of gravity, its right end tends to droop downward, and pulls the right part of the base plate 1 to rotate downward. At this time, the steel wire rope 6 pulls the right part of the base plate 1 upward, so that it cannot rotate downward, that is, the downward rotation tendency of the right end of the steel structure 100 to be installed is locked, so that its inclination angle is consistent with the base plate 1, that is, the hoisting inclination angle of the steel structure 100 to be installed is consistent with the inclination angle required for its installation, and then it is hoisted to the installation position, without the need to perform secondary adjustment on the inclination angle of the steel structure 100 to be installed at a high place, thereby eliminating safety hazards.

[0042] If the installation inclination angle of the steel structure 100 to be installed is in a state of left-higher-right-lower, the sliding block 3 is controlled to descend before hoisting the steel structure 100 to be installed, and the sliding block 3 moves downward to loosen the wire rope 6. At this time, the bottom plate 1 has not hoisted the steel structure 100 to be installed, and its center of gravity is balanced so that the right part of the bottom plate 1 will not rotate downward. At this time, the staff needs to manually press the right part of the bottom plate 1 downward to make it in an inclined state of left-higher-right-lower, and press its right part downward until the wire rope 6 is straightened. At this time, it can be concluded that the wire rope 6 is Under the limitation of the maximum inclination angle of the bottom plate 1, the position of the sliding block 3 is fine-tuned by twisting the rotating ring 5, and then the maximum inclination angle of the bottom plate 1 is fine-tuned by pulling the wire rope 6 until the maximum inclination angle of the bottom plate 1 is consistent with the installation inclination angle of the steel structure 100 to be installed, and then the steel structure 100 to be installed is fixed on the lower side of the bottom plate 1, and is fixed at the left half of the steel structure 100 to be installed by the screw rope 103, so that the hanging of the steel structure 100 to be installed is The center of gravity is located at the right side of the base plate 1. After the steel structure 100 to be installed is lifted, it forms a tendency for the right end to droop downward under the action of gravity, and pulls the right part of the base plate 1 to rotate downward. At this time, the steel wire rope 6 pulls the right part of the base plate 1 upward, so that it cannot rotate downward, that is, the tendency of the right end of the steel structure 100 to be installed to rotate downward is locked, so that its inclination angle is consistent with the maximum inclination angle of the base plate 1, that is, the lifting inclination angle of the steel structure 100 to be installed is consistent with the inclination angle required for its installation, and then it is lifted to the installation position, and there is no need to perform secondary adjustment on the inclination angle of the steel structure 100 to be installed at a high place, which plays the effect of eliminating safety hazards and accelerating installation efficiency; and the screw rod 4 is screwed to the connecting plate 2. If the hoisted steel structure 100 to be installed pulls the sliding block 3 to move downward, there is a tendency to pull the screw rod 4 to move downward relative to the connecting plate 2, and the way in which the screw 4 moves downward relative to the connecting plate 2 will make the threaded fit between the screw 4 and the connecting plate 2 tighter, thereby improving the lifting stability.

[0043] After long-term use, the steel wire rope 6 will inevitably wear out. If part of the steel wire rope 6 is disconnected during the lifting process, since the center of the steel structure 100 to be installed is biased to the right, it will tend to pull the right part of the base plate 1 downward to rotate, which may easily lead to an imbalance in the lifting. If the right part of the base plate 1 rotates downward at too large an angle, it may cause a safety hazard of the steel structure 100 to be installed falling. At this time, through the setting of the safety rope 8, since the length of the safety rope 8 is greater than the length of the steel wire rope 6, the safety rope 8 will not limit the rotation of the base plate 1 during normal use. When the steel wire rope 6 is disconnected and the right part of the base plate 1 can be further rotated downward, the safety rope 8 will be straightened to limit the right part of the base plate 1 to prevent it from further rotating downward, thereby avoiding the safety hazard of falling caused by imbalance in the lifting and improving safety.

[0044] Example 2

[0045] On the basis of Example 1, Figure 1 , Figure 2 and Fig. 9 As shown, a blocking block 201 is also included; two blocking blocks 201 are connected to the left part of the bottom plate 1, and the blocking blocks 201 are used to block the steel structure 100 to be installed, thereby limiting the relative movement between the steel structure 100 to be installed and the bottom plate 1.

[0046] Each blocking block 201 is provided with a guide portion 20101. During installation, the guide portion 20101 is used to guide and limit the steel structure 100 to be installed, so as to facilitate the installation work.

[0047] The blocking block 201 is connected to the bottom plate 1 by bolts, so that the blocking block 201 can be easily disassembled.

[0048] The lower side of the bottom plate 1 is rough, and the facing sides of the clamping plate 105 and the rope pushing plate 108 are rough, so as to strengthen the clamping friction of the bottom plate 1, the clamping plate 105 and the rope pushing plate 108 on the steel structure 100 to be installed.

[0049] The specific working steps are:

[0050] Considering that the steel structure 100 to be installed is in an inclined state during the hoisting process, its center of gravity is not in the middle of the bottom plate 1, and there is a tendency for the steel structure 100 to be installed to slide toward the inclined downward side. During the outdoor hoisting process, if the wind is too strong to cause the hoisting structure to shake, it is more likely to cause the steel structure 100 to be installed to slide relative to the bottom plate 1, and there is a safety hazard of slipping and falling in the inclined downward direction. If the steel structure 100 to be installed is inclined with the left side higher and the right side lower during hoisting, then when the steel structure 100 to be installed is fixed to the lower side of the bottom plate 1, the lower end of the blocking block 201 is inserted into the right side of a steel frame of the steel structure 100 to be installed, such as Fig. 9 In the state shown in the middle left figure, if the steel structure 100 to be installed accidentally slides to the right, the lower end of the blocking block 201 can be used to abut against the right side of the steel frame of the steel structure 100 to prevent it from sliding further to the right, thereby enhancing the safety of the operation; if the steel structure 100 to be installed is tilted with the left side lower and the right side higher during hoisting, when the steel structure 100 to be installed is fixed to the lower side of the base plate 1, the lower end of the blocking block 201 is inserted into the left side of a steel frame of the steel structure 100 to be installed, such as Fig. 9 In the state shown in the middle right figure, if the steel structure 100 to be installed accidentally slides to the left, the lower end of the blocking block 201 can be used to support the left side of the steel frame of the steel structure 100 to be installed to prevent it from sliding further to the left, thereby avoiding a safety accident of the steel structure 100 to be installed slipping and falling.

[0051] Secondly, during the installation work, if the steel structure 100 to be installed shakes or slides, it will increase the difficulty of the installation work and easily crush the workers' fingers. Therefore, during the installation, when the steel structure 100 to be installed is aligned with the installation position, first control the crane to lower the base plate 1 and the steel structure 100 to be installed until the guide part 20101 of the blocking block 201 overlaps with the upper part of the installed steel structure. Under the action of gravity, the guide part 20101 will be pressed on the upper side of the installed steel structure, making the guide part 20101 a support point, thereby enhancing the stability when installing the steel structure 100 to be installed and avoiding the problem of shaking or sliding of the steel structure 100 to be installed during the installation process.

[0052] When the steel structure 100 to be installed is hoisted in a horizontal state, although the middle part of the steel structure 100 to be installed is fixed by the screw rope 103 to balance its center of gravity, due to uncontrollable factors such as external wind interference during the hoisting process, the steel structure 100 to be installed will swing slightly and tilt. At this time, the positioning plate 105 and the rope pushing plate 108 tighten the screw rope 103 in the direction of the steel structure 100 to be installed, and the screw rope 103 pulls up the steel structure 100 to be installed. The structure 100 is in close contact with the lower side of the base plate 1, and the facing sides of the positioning plate 105 and the push rope plate 108 are also in contact with the steel structure 100 to be installed, so that the steel structure 100 to be installed is tightly clamped. Therefore, the lower side of the base plate 1 and the facing sides of the positioning plate 105 and the push rope plate 108 are roughened, thereby strengthening the clamping friction of the base plate 1, the positioning plate 105 and the push rope plate 108 on the steel structure 100 to be installed, so that the steel structure 100 to be installed is not easy to slide relative to the base plate 1, thereby improving the lifting stability.

[0053] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
