Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a reinforcement cage butt adjustment device. Background Art

[0002] For the construction of super-long pile foundations, it is necessary to prepare a correspondingly long steel cage. In order to facilitate processing and transportation, the steel cage is usually manufactured in sections, for example, each section is 9 meters long. During the construction process, the segmented steel cages are lowered into the pile hole in turn, and in the process of lowering them in batches, the subsequent steel cages to be lowered are lifted to the top of the pile hole by a crane, and then the steel cage to be installed is aligned with the steel cage that has been lowered, and then the main steel bars of the upper and lower steel cages are fixed with a threaded sleeve. Only after the upper and lower steel cages are fixedly connected can the steel cages continue to be lowered.

[0003] At present, when connecting the upper and lower steel cages, the steel cage on the upper side is lifted by a crane. Since the single-section steel cage is long and heavy, the steel cage on the upper side is prone to shaking and causing displacement deviation when aligning the upper and lower steel cages, resulting in the upper and lower steel cages being unable to be accurately connected. At present, the process of connecting the threaded sleeve is done manually. When the main reinforcement is not aligned, manual adjustment is required, which is inconvenient and very laborious, resulting in low efficiency of steel cage connection. Utility Model Content

[0004] The utility model aims to provide a reinforcement cage butt adjustment device to solve the problems of inconvenient operation and low efficiency when connecting the main reinforcement of the reinforcement cage in the prior art.

[0005] To solve the above problems, the utility model adopts the following technical solutions: a steel cage docking adjustment device, comprising two fixing mechanisms arranged in pairs and a positioning piece arranged between the two fixing mechanisms, the fixing mechanism comprising a semicircular base and a fixing unit for fixing the main reinforcement, the number of the semicircular bases is two and the two semicircular bases are detachably connected, the two semicircular bases are used to connect to form a circular limiting ring, the number of the fixing units is several and all the fixing units are evenly arranged on the inner side wall of the limiting ring, and the positioning piece is used to drive the fixing units between the two fixing mechanisms to correspond one to one in the vertical direction.

[0006] The principle of this solution is: in this application, two fixing mechanisms are set up, and the two fixing mechanisms are respectively set corresponding to the upper and lower steel cages. When in use, one of the fixing mechanisms is connected to the top end of the lower steel cage, and the other fixing mechanism is connected to the bottom end of the upper steel cage.

[0007] Taking the connection between one of the fixing mechanisms and the steel cage as an example, during the connection process, the two semicircular bases are first fixedly connected from a separated state to an interconnected state. At this time, the two semicircular bases form a circular limiting ring, and the limiting ring receives all the main bars of the steel cage in the limiting ring. At this time, the annular structure of the limiting ring can be used to initially limit the main bars, and then the main bars are fixed using fixing units evenly arranged along the circumferential direction of the inner wall of the limiting ring. The number of fixing units is equal to the number of main bars and is set one-to-one to ensure that all main bars can be fixed by the fixing units.

[0008] After the two fixing mechanisms are respectively connected to the ends of the two steel cages, the upper steel cage is released downward by using a crane in the prior art. When the upper steel cage moves downward, the upper fixing mechanism and the steel cage are positioned by using the positioning pieces arranged between the two fixing mechanisms, so that all the fixing units in the two fixing mechanisms correspond one to one in the vertical direction, thereby ultimately ensuring that the main bars of the upper steel cage can be accurately aligned with the main bars of the lower steel cage in the vertical direction, so that the main bars of the two steel cages can be quickly and accurately fixed and connected by using a threaded sleeve.

[0009] The beneficial effects of this program are:

[0010] 1. Ability to quickly and accurately complete the alignment connection of the steel cage: In the present application, by setting a fixing mechanism and a positioning member, during the alignment connection process of the upper and lower steel cages, relying on the positioning function of the positioning member, the fixing units of the two fixing mechanisms correspond one to one in the vertical direction, so that the main bars of the two steel cages are quickly and accurately aligned in the vertical direction. Moreover, due to the relationship between the fixing mechanism and the positioning mechanism, the steel cage in the hoisting state on the upper side can be limited, effectively reducing the shaking of the upper steel cage when installing the threaded sleeve, etc., further improving the accuracy of the steel cage installation.

[0011] 2. Very convenient for assembly and disassembly: In this application, since the two semicircular bases are detachably connected, after completing the alignment of the two steel cages, first loosen the fixing unit and the main reinforcement, and then disassemble the two semicircular bases. Since all the main reinforcements are located in the limiting ring surrounded by the two semicircular bases, the entire device can be easily disassembled from the steel cage, and the operation is very convenient.

[0012] 3. Ability to fine-tune the main reinforcement: In this application, when the two semicircular bases are first fixed, all the main reinforcements will be surrounded by the limiting rings formed by the two semicircular bases. At this time, the main reinforcement can be adjusted once, and then the fixing unit is used to fix the main reinforcement. Since the fixing unit and the main reinforcement are set one-to-one, and the position of the fixing unit and the semicircular base is relatively fixed, when the main reinforcement is fixed by the fixing unit, even if the position of the main reinforcement is offset, the position of the main reinforcement can be accurately adjusted, and the main reinforcement can be adjusted for the second time to ensure that the main reinforcement of the two steel cages can be accurately aligned after the fixing operation is completed, thereby improving the accuracy of the steel cage installation and docking.

[0013] 4. Reusable: The steel cage docking adjustment device in this application can be reused many times, and the equipment utilization rate is high.

[0014] Preferably, as an improvement, one end of the two semicircular bases are rotatably connected, and a detachable connecting piece is provided between the other ends.

[0015] In this solution, one end of the two semicircular bases is rotatably connected, and a detachable connecting piece is set at the other end. When in use, you only need to rotate the two semicircular bases, and then use the detachable connecting piece to connect the free ends of the two semicircular bases, so that the two semicircular bases can be quickly connected, which is very convenient to operate.

[0016] Preferably, as an improvement, the fixing unit comprises a fixed semicircular sleeve, a movable semicircular sleeve and a driving member, the fixed semicircular sleeve is fixedly connected to the inner side of the semicircular base, the movable semicircular sleeve is rotatably connected to the fixed semicircular sleeve and is used to form a fixed ring with the fixed semicircular sleeve for fixing the main reinforcement; the driving member is connected to the fixed semicircular sleeve or the semicircular base, and the driving member drives the movable semicircular sleeve to rotate until it forms a fixed ring with the fixed semicircular sleeve.

[0017] In this solution, when fixing the main reinforcement, the movable semicircular sleeve is first rotated to a state away from the fixed semicircular sleeve, and then the position of the limit ring and the fixed semicircular sleeve is adjusted so that the main reinforcement is basically located in the arc space of the fixed semicircular sleeve. The driving member is then used to drive the movable semicircular sleeve to rotate, so that the movable semicircular sleeve and the fixed semicircular sleeve form a fixed ring, and the main reinforcement is locked and fixed in the fixed ring, thereby fixing the main reinforcement.

[0018] Preferably, as an improvement, a torsion spring is fixedly connected between the movable semicircular sleeve and the fixed semicircular sleeve, and when not subjected to external force, the movable semicircular sleeve is in a state of rotating away from the fixed semicircular sleeve.

[0019] In this solution, a torsion spring is arranged between the movable semicircular sleeve and the fixed semicircular sleeve. When not subjected to external force, the movable semicircular sleeve is in an open state rotated away from the fixed semicircular sleeve, so that the semicircular base can be rotated with the fixed semicircular sleeve to quickly position the main reinforcement in the arc space of the fixed semicircular sleeve, thereby improving the efficiency of fixing the main reinforcement.

[0020] Preferably, as an improvement, the driving member includes a rotating arm and a driving block fixedly connected to the rotating arm, and the outer side of the rotating arm is rotatably connected to a fixed semicircular sleeve or a semicircular base; a driving inclined surface is provided on the driving block, and the outer side of the movable semicircular sleeve is provided with a mating inclined surface that cooperates with the wedge surface of the driving inclined surface.

[0021] In this solution, by rotating the rotating arm, the driving block on the rotating arm can be used to drive the movable semicircular sleeve to rotate relative to the fixed semicircular sleeve, and finally the movable semicircular sleeve is rotated to form a fixed ring state with the fixed semicircular sleeve, so that the main reinforcement is in a locked and fixed state, so as to be connected with the main reinforcement of another steel cage later.

[0022] Preferably, as an improvement, the rotating arm is rotatably connected to the semicircular base, a avoidance groove is provided on the semicircular base, and the free end of the rotating arm passes through the avoidance groove and extends outside the outer wall of the semicircular base.

[0023] In this solution, the free end of the rotating arm extends beyond the outer wall of the semicircular base, and the rotating arm can be manually pushed to rotate very conveniently during the process of fixing the main reinforcement, which is more convenient to use.

[0024] Preferably, as an improvement, the rotating arm rotates along the vertical direction.

[0025] In this solution, the rotation direction of the rotating arm is set along the vertical direction, which reduces the mutual influence between adjacent rotating arms and enables better arrangement of the rotating arms.

[0026] Preferably, as an improvement, a locking groove is provided on the semicircular base, and a locking piece that is locked with the locking groove is movably connected on the rotating arm, and when the driving block drives the movable semicircular sleeve to rotate to form a fixed ring with the fixed semicircular sleeve, the locking piece is locked and fixed with the locking groove.

[0027] In this solution, by setting a locking piece and a locking groove structure, when the movable semicircular sleeve is rotated to lock and fix the main reinforcement, the locking piece is locked and fixed with the locking groove, so as to avoid the loosening of the movable semicircular sleeve when connecting the main reinforcement of two steel cages, which will cause the accuracy of main reinforcement connection to be reduced, making the main reinforcement connection process more stable.

[0028] Preferably, as an improvement, the locking member includes a locking rod, an elastic reset member and a switch pressure rod, the locking rod is slidably connected to the rotating arm, the elastic reset member is connected between the locking rod and the rotating arm, the side wall of the switch pressure rod is rotatably connected to the rotating arm, the switch pressure rod and the rotating arm form a lever, and one end of the switch pressure rod is in contact with an end of the locking rod close to the rotating arm.

[0029] In the present solution, a locking rod and an elastic reset member are utilized. When the movable semicircular sleeve is rotated to lock the main reinforcement, the locking rod is inserted into the locking groove. Under the elastic force of the elastic reset member, the locking rod can be ensured to be always inserted into the locking groove without being subjected to external force, so that the movable semicircular sleeve cannot be reversed and loosened, thereby making the main reinforcement firmly clamped and locked. When the steel cage is docked and fixed, it is only necessary to drive the locking rod out of the locking groove. Under the torsion of the torsion spring, the movable semicircular sleeve automatically rotates and opens, so that the fixed semicircular sleeve and the movable semicircular sleeve can be conveniently removed. The structure is simple and the locking effect is stable.

[0030] Preferably, as an improvement, the positioning member includes positioning rods and positioning holes that are plugged into each other, the number of the positioning rods is at least two, and when the positioning rods are plugged into the positioning holes, the multiple fixing units in the two fixing mechanisms are arranged one by one in the vertical direction.

[0031] In this solution, by relying on the positioning of at least two positioning rods, the two fixing mechanisms can be conveniently and accurately docked, so that the two steel cages are accurately aligned, the structure is simple and the docking process is easy to operate.

[0040] Embodiment 1

[0041] This embodiment is as shown in the attached Figure 1 and Figure 2 As shown: A reinforcement cage docking adjustment device comprises two vertically paired fixing mechanisms and a positioning member arranged between the two fixing mechanisms. Figure 3 The fixing mechanism includes a semicircular base 1 and a fixing unit for fixing the main rib 2, wherein the number of the semicircular bases 1 is two and the two semicircular bases 1 are detachably connected, one end of the two semicircular bases 1 is rotatably connected by a pin shaft, and a detachable connecting piece is provided between the other ends (i.e., the free ends), and the two semicircular bases 1 can be fixedly connected by the detachable connecting piece, so that the two semicircular bases 1 are surrounded by a circular limiting ring. Specifically, the detachable connecting piece in this embodiment adopts a bolt structure, and a connecting seat 3 is integrally formed at the free end of the semicircular base 1, and a fixing hole 301 is opened on the connecting seat 3. When it is necessary to fix the free ends of the two semicircular bases 1, it is only necessary to insert the bolt into the fixing hole 301 to fix it. In other embodiments other than this embodiment, the free ends of the semicircular bases 1 can also be fixed by structures such as buckles, as long as the free ends of the two semicircular bases 1 can be stably fixed, and its implementation methods are not listed one by one here.

[0042] like Figure 2 As shown, the number of fixed units in the fixing mechanism is several and the several fixed units are evenly and equidistantly arranged along the inner wall arc direction of the semicircular base 1. The number of fixed units needs to be determined according to the number of main bars 2 in the fixed steel cage to ensure that each main bar 2 is provided with a corresponding fixed unit. In this embodiment, the fixed unit includes a fixed semicircular sleeve 4, a movable semicircular sleeve 5 and a driving member. The fixed semicircular sleeve 4 is welded to the inner wall of the semicircular base 1, and combined with the semicircular sleeve 4, the movable semicircular sleeve 5 and the driving member are provided. Figure 3 and Figure 4 The fixed semicircular sleeve 4 is provided with a vertically penetrating semicircular groove, and the movable semicircular sleeve 5 is rotatably connected to the fixed semicircular sleeve 4 through a pin shaft. The movable semicircular sleeve 5 is also provided with a vertically penetrating semicircular groove. When the movable semicircular sleeve 5 is rotated to fit with the fixed semicircular sleeve 4, the fixed semicircular sleeve 4 and the movable semicircular sleeve 5 form a vertically penetrating fixed collar 6, and the inner diameter of the fixed collar 6 is equal to the diameter of the main reinforcement 2, so that the main reinforcement 2 can be stably locked and fixed in the fixed collar 6.

[0043] In this embodiment, the driving member is connected to the fixed semicircular sleeve 4 or the semicircular base 1, and the driving member can drive the movable semicircular sleeve 5 to rotate to form a fixed collar 6 with the fixed semicircular sleeve 4, so that the main reinforcement 2 is tightly locked. Figure 2 and Figure 3 As shown, an implementation method is illustrated, the driving member includes a rotating arm 7 and a driving block 8 fixedly connected to the rotating arm 7, the rotating arm 7 is rotatably connected to the semicircular base 1 by a pin shaft, and the rotating direction of the rotating arm 7 is located in a vertical plane. In order to facilitate the manual pushing of the rotating arm 7 to rotate, in this embodiment, a vertically arranged avoidance groove 101 is opened on the semicircular base 1, and the free end of the rotating arm 7 passes through the avoidance groove 101 and extends to the outside of the outer wall of the semicircular base 1. The driving block 8 is fixedly connected to one end of the rotating arm 7 located on the inner side of the semicircular base 1 by a screw, the driving block 8 is located on one side of the movable semicircular sleeve 5, and the driving block 8 is opened on the side facing the movable semicircular sleeve 5. A matching bevel 501 that matches the wedge surface of the driving bevel 801 is provided on the outer side of the movable semicircular sleeve 5. When the driving block 8 rotates in the vertical direction following the rotating arm 7, the movable semicircular sleeve 5 can be pushed to rotate and surround the fixed semicircular sleeve 4 to form a fixed ring 6, thereby locking and fixing the main reinforcement 2.

[0044] In this embodiment, for the convenience of operation, a torsion spring is installed between the movable semicircular sleeve 5 and the fixed semicircular sleeve 4. When the movable semicircular sleeve 5 is not subjected to external force, the movable semicircular sleeve 5 is located away from the fixed semicircular sleeve 4, so as to adjust the position of the fixed semicircular sleeve 4 and the semicircular base 1, so that the main reinforcement 2 can be located as much as possible in the semicircular groove of the fixed semicircular sleeve 4, thereby ensuring that the main reinforcement 2 can be accurately fixed later.

[0045] like Figure 2 As shown, the positioning member in this embodiment includes a positioning rod 9 and a positioning hole that are plugged into each other. The positioning rod 9 is fixedly connected to the semicircular base 1 in one of the fixing mechanisms, and the positioning hole is opened on the semicircular base 1 of the other fixing mechanism. The positions of the two can be selected according to the actual construction situation and will not be repeated here. At the same time, for the accuracy of positioning, the number of positioning rods 9 is at least two, and preferably three in this embodiment.

[0046] The specific implementation process is as follows:

[0047] When two steel cages need to be docked and fixed, first, two fixing mechanisms are fixedly connected to the two steel cages respectively, and then the crane in the prior art is used to lift the steel cage that can be lifted, and the fixing mechanism on the lifted steel cage is located at the bottom of the steel cage, so that the fixing mechanism on the lifted steel cage can cooperate with the fixing mechanism on the other steel cage. Then the lifted steel cage is moved to the top of the other steel cage, so that the two steel cages are roughly located on the same vertical line, and then the upper steel cage is gradually moved down, and the positioning function of the positioning rod 9 and the positioning hole is used to dock the two steel cages, and under the positioning function of the positioning rod 9 and the positioning hole, the fixing units in the two fixing mechanisms correspond one to one in the vertical direction, ensuring that after the two steel cages are vertically docked, the main bars 2 of the two steel cages correspond one to one in the vertical direction and are in a coaxial state. At this time, the threaded sleeves 10 in the prior art can be used to fix the ends of the corresponding two main bars 2, and the operation is very simple. After all the threaded sleeves 10 are fixed, the fixing of the fixing unit to the main bars 2 is loosened, and then the bolts between the semicircular bases 1 are opened, and then the entire device can be disassembled.

[0048] Embodiment 2

[0049] The difference between the second embodiment and the first embodiment is that: Figure 5 and Figure 6 In this embodiment, a locking groove 102 is opened on the inner wall of the avoidance groove 101 on the semicircular base 1, and a locking piece that is locked with the locking groove 102 is movably connected on the rotating arm 7. When the driving block 8 drives the movable semicircular sleeve 5 to rotate to form a fixed ring 6 with the fixed semicircular sleeve 4, the locking piece is locked and fixed with the locking groove. Specifically, the locking member in this embodiment includes a locking rod 11, an elastic reset member and a switch pressure rod 12. A sliding hole 701 is opened on the rotating arm 7. The locking rod 11 is slidably connected to the sliding hole 701. The elastic reset member is connected between the locking rod 11 and the rotating arm 7. In this embodiment, the elastic reset member is a reset spring 13 sleeved on the locking rod 11. A limiting protrusion 1101 for limiting the reset spring 13 is integrally formed on the side wall of the locking rod 11. In addition, the side wall of the switch pressure rod 12 is rotatably connected to the rotating arm 7. The switch pressure rod 12 and the rotating arm 7 form a lever, and one end of the switch pressure rod 12 is in contact with the end of the locking rod 11 close to the rotating arm 7.

[0050] When the switch pressure rod 12 is not subjected to external force, under the support of the elastic force of the return spring 13, one end of the locking rod 11 slides out of the sliding hole 701. At this time, the end of the locking rod 11 can be inserted into the locking groove 102 to prevent the rotating arm 7 from rotating. At this time, under the driving action of the driving block 8, the movable semicircular sleeve 5 and the fixed semicircular sleeve 4 are in a state of fixing the main reinforcement 2, thereby avoiding the loosening of the movable semicircular sleeve 5 during lifting or docking, which causes the two main reinforcements 2 to be unable to be accurately aligned, thereby ensuring the accuracy of the docking of the main reinforcement 2.

[0051] After the two butted main bars 2 are fixed by the threaded sleeve 10, it is only necessary to manually press the switch pressure rod 12 so that the switch pressure rod 12 pushes the locking rod 11 to slide into the sliding hole 701. At this time, the rotating arm 7 is pushed to rotate so that the force of the driving block 8 on the movable semicircular sleeve 5 disappears. Under the action of the torsion spring, the movable semicircular sleeve 5 automatically rotates to a state away from the fixed semicircular sleeve 4, so that the entire device can be easily disassembled from the steel cage later.

[0052] Of course, in this embodiment, in order to enable the locking rod 11 to automatically enter the locking groove 102 during the rotation of the rotating arm 7, a guiding slope that cooperates with the end of the locking rod 11 can be opened on the inner wall of the avoidance groove 101. When the locking rod 11 follows the rotating arm 7 to slide toward the semicircular base 1, under the guidance of the guiding slope, the locking rod 11 automatically slides into the sliding hole 701, and when the end of the locking rod 11 moves to the locking groove 102, it is automatically pushed out and locked with the locking groove 102 under the elastic force of the reset spring 13, which is more convenient to operate.

[0053] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
