[0002] In the field of construction engineering, steel cages are widely used. In large-scale construction projects, such as high-rise buildings, large bridges, underground continuous walls, etc., the depth of the foundation structure is large, and the required length of the steel cage often exceeds the production length of a single-section steel cage. Therefore, the steel cage needs to be connected up and down to meet the above-mentioned project's demand for longer steel cages and ensure that the foundation structure can penetrate to a sufficient depth to provide stable support.

[0003] The related art (publication number CN110616640A) discloses a steel cage positioning and lowering device and a construction method thereof, including a pad and a positioning mechanism, a first through hole is provided on the pad, the pad is used to be arranged on the top of the pile hole, a second through hole is provided on the positioning mechanism, the positioning mechanism is arranged on the top of the pad, and the first through hole and the second through hole are used to form a lowering channel with the pile hole, at least three positioning holes are provided on the side of the positioning mechanism at intervals, and a positioning member is movably provided on each positioning hole, the positioning member can move in the positioning hole in a direction close to or away from the lowering channel, and one end of the positioning member is extended into the lowering channel to fix the steel cage segment lowered into the lowering channel. A steel cage positioning and lowering device and a construction method thereof are provided, which can assist the steel cage segments to complete the docking more quickly and efficiently, and is easier to separate from the steel cage, with a high safety factor.

[0004] However, when the existing steel cages are butt-jointed, due to the lack of effective positioning devices and precise butt-jointing means, it is often difficult to ensure that the two steel cages are aligned in the same line at the joint. Therefore, before installing the connecting sleeve at the joint of the two steel cages, it is necessary to manually adjust the positions of the two steel cages repeatedly; however, the two steel cages are prone to angular deviation and horizontal offset during the manual adjustment process. In addition, the accuracy of manual adjustment is limited, and it is difficult to achieve the ideal co-linear alignment of the two steel cages. In addition, the manual adjustment method reduces the efficiency of the steel cage butt-jointing installation and prolongs the project progress. Summary of the invention

[0025] The present invention also provides a method for butt jointing a reinforcement cage butt jointing device, comprising the following steps:

[0026] S1. Equipment adjustment:

[0027] Move the docking device to the rear side of the steel cage, and cause the first fixed seat and the first fixed seat in the separated state to be located on the left and right sides of the steel cage respectively, so as to adjust the initial position of the equipment;

[0028] S2. Equipment weight:

[0029] Adjust the base plate to fit the ground, and place weight blocks of appropriate weight on the base plate;

[0030] S3. docking the first fixed seat with the first fixed seat, the first rotating seat with the second rotating seat:

[0031] By docking the two sets of positioning components, the first fixed seat and the first fixed seat, the first rotating seat and the second rotating seat are docked respectively, so that the first fixed seat and the first fixed seat are connected to form an annular seat with a hollow annular space, and the first rotating seat and the second rotating seat are connected to form an annular plate. At this time, the steel cage is located in the middle of the annular seat formed by the first fixed seat and the first fixed seat;

[0032] S4. Preliminary connection of upper and lower reinforcement cages:

[0033] By means of a lifting device, the upper steel cage is lifted to the first fixed seat and the steel cage inside the first fixed seat, and the steel bars of the upper steel cage are positioned between the two clamping claws above the movable plate, and the steel bars of the lower steel cage are positioned between the two clamping claws below the movable plate;

[0034] S5. Upper and lower reinforcement cages are connected in line:

[0035] The docking unit causes each set of corresponding clamps at all movable plates to rotate synchronously toward the middle, so as to clamp and limit the steel bars of the upper and lower steel cages respectively, so as to achieve the co-linear docking of the steel bars of the upper and lower steel cages;

[0036] S6. Connect the upper and lower reinforcement cages after collinear docking:

[0037] The existing connection sleeve is threadedly sleeved on the steel bar connection of the two steel bar cages, thereby realizing the collinear connection of the upper and lower sets of steel bar cages;

[0038] S7. Remove the docking device from the steel cage.

[0039] Compared with the prior art, the steel cage butt joint device and the butt joint method of the present invention have the following beneficial effects:

[0040] 1. When the existing steel cages are butt-jointed, due to the lack of effective positioning devices and precise butt-jointing means, it is often difficult to ensure that the butt joint of the two steel cages is aligned in the same line up and down. Therefore, before installing the connecting sleeve at the butt joint of the two steel cages, it is necessary to manually and repeatedly adjust the positions of the two steel cages. The present invention can quickly position the upper and lower steel cages to ensure that the two butt jointed steel cages can be aligned in the same line up and down, so as to facilitate the subsequent precise butt joint of the connecting sleeves at the butt joint of the two steel cages. Compared with the manual repeated adjustment method, it is more accurate and effectively avoids the problem of angle deviation and horizontal offset of the two steel cages caused by manual adjustment.

[0041] Second, the present invention adopts the upper and lower corresponding clamping jaws to clamp synchronously towards the middle, which can dock the upper and lower steel cages in the same line, and by driving the fixed frame and the movable plate at the corresponding position of all the movable frames to move, all the upper and lower corresponding clamping jaws can be clamped synchronously towards the middle or unfolded outward, that is, the upper and lower steel cages can be docked at all circumferential angles at one time, which is more efficient than the traditional manual docking method of adjusting the docking angles one by one, effectively shortening the project progress and improving the construction efficiency;

[0042] 3. The present invention can promote the synchronous movement of all moving pins, moving frames and moving plates through cylinders, spur racks, rotating shafts, gears and arc-shaped racks, that is, the linkage of all moving frames can be realized through the same driving force, which saves driving force and ensures the synchronization of the movement of all moving frames, thereby ensuring that the clamps at various angles corresponding to the moving frames can be synchronously clamped to the middle or expanded to the outside, so as to synchronously limit and dock the upper and lower steel cages at various angles;

[0043] Fourth, the present invention can limit the rotation direction of the first rotating seat and the second rotating seat by setting the limiting rod and the moving frame, so as to ensure that the first rotating seat and the second rotating seat can rotate stably in the first fixed seat and the first fixed seat, so as to keep all the driving slots stable during the rotation process;

[0044] 5. The existing traditional docking method requires the use of lifting equipment to set the docking device from top to bottom on the side wall of the steel cage. It is inconvenient to repeatedly adjust the lifting equipment, which increases the construction steps. In addition, some lifting equipment cannot be hoisted due to space limitations at the construction site, which easily leads to the problem of limited docking of the steel cage. The docking device of the present invention adopts a split design. The first fixed seat and the first fixed seat can be flexibly connected or disassembled, and the first rotating seat and the second rotating seat can be flexibly connected or disassembled. The device can be assembled on the side wall of the steel cage from the side. Compared with the traditional method of setting the docking device from top to bottom on the side wall of the steel cage with the help of lifting equipment, the operation is more convenient, saving the cumbersome steps of operating the lifting equipment, and avoiding the problem of limited steel cage docking construction due to limited use of lifting equipment;

[0045] Sixth, the present invention can promote the insertion of the U-shaped plug between the two into the slot cavity at the corresponding position through the first fixed seat and the first fixed seat that are close to each other, and automatically realize the locking limit of the U-shaped plug inserted into the slot cavity, that is, through the first fixed seat and the first fixed seat that are close to each other, automatic locking and docking can be realized, so that the first fixed seat and the first fixed seat form a stable annular positioning space. Similarly, through the first rotating seat and the second rotating seat that are close to each other, automatic locking and docking can be realized between the two, so that the first rotating seat and the second rotating seat form a stable whole, ensuring that the first rotating seat and the second rotating seat can rotate synchronously after locking and docking;

[0046] 7. The present invention can move the device from the back to the front through the first fixed seat and the first fixed seat, the first rotating seat and the second rotating seat in the separated state, so that the steel cage is located in the middle of the device, and the first fixed seat and the second rotating seat can be stably supported by the supporting platform, and at the same time, when the movable arm moves in the direction close to the fixed arm, the first fixed seat and the second rotating seat are gradually docked with the first fixed seat and the first rotating seat respectively, so as to dock the steel cage later;

[0047] 8. The present invention can drive the movable arm, the supporting platform and the components arranged on the supporting platform to move synchronously to the left or right through the motor, the lead screw, the polished rod and the slider, thereby realizing that the first fixed seat moves closer to the first fixed seat to the left or moves away from the first fixed seat to the right;

[0048] 9. The present invention is provided with a moving rod and a limiting piece, through which the relative movement of the moving arm with respect to the fixed arm can be limited, and through which the moving arm with respect to the fixed arm can be limited, so as to ensure that when the limiting piece moves to fit the right side wall of the fixed arm, the first fixing seat and the first fixing seat can be locked and docked accurately;

[0049] 10. The present invention is provided with a fixed platform, a lifting column, a bottom plate, and a screw rod, and the position of the bottom plate can be lifted and adjusted. By adjusting the bottom plate to fit the ground and placing a counterweight on the bottom plate, the overall balance of the equipment is maintained, and the equipment is kept in a vertically stable state during the docking of the steel cage, thereby ensuring the normal docking of the steel cage. In addition, the bottom plate that is lifted upward and off the ground will not affect the movement and transportation of the overall equipment, and is flexible and convenient to use;

[0050] In summary, the present invention can quickly position the upper and lower steel cages, ensuring that the two steel cages after docking can be aligned in the same line up and down, so as to facilitate the precise docking of the connecting sleeves at the docking point of the two steel cages. Compared with the method of repeated manual adjustment, it is more accurate, and effectively avoids the problem of angle deviation and horizontal offset of the two steel cages caused by manual adjustment. In addition, all the upper and lower corresponding jaws are synchronously clamped toward the middle or expanded outward, that is, the upper and lower steel cages can be docked at all circumferential angles at one time, which is more efficient than the traditional method of manually adjusting the docking angles one by one, effectively shortening the project progress and improving the construction efficiency. In addition, the docking device adopts a split design, which can be assembled on the side wall of the steel cage from the side. Compared with the traditional method of using lifting equipment to sleeve the docking device from top to bottom on the side wall of the steel cage, it is more convenient to operate, saves the cumbersome steps of operating the lifting equipment, and avoids the problem of limited steel cage docking construction due to limited use of lifting equipment.

DETAILED DESCRIPTION

[0064] The following is a combination of specific implementation cases and attached Figures 1 to 12 The present invention is further described below, but the present invention is not limited to these embodiments.

[0065] When docking existing steel cages, due to the lack of effective positioning devices and precise docking means, it is often difficult to ensure that the two steel cages are aligned vertically at the docking point. Therefore, before installing the connecting sleeve at the docking point of the two steel cages, it is necessary to manually adjust the positions of the two steel cages repeatedly. Figures 1 to 12As shown, a reinforcement cage docking device is now proposed, including a seat body 1, the seat body 1 includes a first fixed seat 1001, a first fixed seat 1002, a first rotating seat 1003 and a second rotating seat 1004, the first fixed seat 1001 and the first fixed seat 1002, the first rotating seat 1003 and the second rotating seat 1004 are detachably connected through two sets of positioning components, the first fixed seat 1001 and the first fixed seat 1002 are connected to form an annular seat with a hollow annular space, the first rotating seat 1003 and the second rotating seat 1004 are connected to form an annular plate, the first rotating seat 1003 and the second rotating seat 1004 are relative to the first fixed seat 100 1 and the first fixed seat 1002 inner cavity rotation arrangement, that is, the annular plate can rotate relative to the annular seat under the action of external force, the first rotating seat 1003 and the second rotating seat 1004 are provided with a plurality of driving grooves 2 equidistantly along the circumferential direction, and each driving groove 2 is inclined from the inside to the outside, and a moving pin 3 is slidably embedded in the inner cavity of each driving groove 2. Through the rotation of the first rotating seat 1003 and the second rotating seat 1004, the driving groove 2 can drive the moving pin 3 to move, and a docking unit is respectively installed on the top of each moving pin 3. Through the movement of the moving pin 3, the docking unit is prompted to limit the steel cage, so that the upper and lower steel cages are in a vertical collinear state.

[0066] Main references Figures 2 to 5 As shown, the docking unit includes a mobile frame 5 rotatably connected to the top of the mobile pin 3 through a bearing. When the driving slot 2 rotates, the mobile pin 3 can drive the mobile frame 5 to move synchronously. It also includes a connecting block 9 fixedly installed on the upper surfaces of the first fixed seat 1001 and the first fixed seat 1002. The top of the connecting block 9 is fixedly installed with a fixed frame 6, and the end of the mobile frame 5 slides through the fixed frame 6 and extends into the inner cavity of the fixed frame 6. The fixed seat 6 can be fixedly connected to the first fixed seat 1001 and the first fixed seat 1002 through the connecting block 9 to achieve the fixed installation of the fixed seat 6, so that the mobile frame 5 is driven to move along the inner cavity of the fixed seat 6. The end of the mobile frame 5 extending into the inner cavity of the fixed frame 6 is fixedly installed with a mobile plate 7. The movement of the mobile frame 5 drives the mobile plate 7 to move synchronously. Each mobile plate 7 is collinearly arranged with two groups of docking components 8 respectively. The movement of the mobile plate 7 prompts the two groups of docking components 8 arranged collinearly to be synchronously clamped toward the middle, so as to achieve synchronous collinear positioning of the steel bars of the upper and lower groups of steel cages.

[0067] Main references Figure 5As shown, each docking assembly 8 includes a first rotating rod 8001 rotatably connected to the movable plate 7 via a pin, and also includes a second rotating rod 8003 rotatably connected to the first rotating rod 8001 via a pin, a mounting plate 8002 is fixedly installed on the side of the fixed frame 6 away from the movable frame 5, the second rotating rod 8003 is rotatably connected to the mounting plate 8002 via a pin, and a clamping claw 8004 is fixedly installed on the side of the second rotating rod 8003 away from the first rotating rod 8001; wherein, the two clamping claws 8004 in each docking assembly 8 are arranged opposite to each other, and the two clamping claws 8004 are arranged on opposite sides with an inner concave arc surface;

[0068] As the first rotating seat 1003 rotates, the movable pin 3 embedded in the sliding driving groove 2 is forced to move along the inner cavity of the driving groove 2, and the movable pin 3 drives the movable frame 5 to move synchronously toward the middle of the equipment, so as to drive the movable plate 7 to move synchronously toward the middle of the equipment. The movement of the movable plate 7 drives the upper and lower groups of first rotating rods 8001 to respectively drive the upper and lower groups of second rotating rods 8003 to rotate synchronously relative to each other, so as to realize the upper and lower groups of clamps 8004 to rotate synchronously relative to each other; the upper group of clamps 8004 clamps and positions the steel bars of the upper steel cage, and the lower group of clamps 8004 clamps and positions the steel bars of the lower steel cage. In addition, since the upper and lower groups of clamps 8004 are arranged correspondingly up and down, and the upper and lower groups of clamps 8004 are synchronously driven by the movable plate 7, the synchronous clamping and positioning of the steel bars at the upper and lower steel cages can be realized, and the two steel cages after positioning are ensured to be collinear up and down. After positioning, the existing connecting sleeve is threadedly sleeved on the steel bar connection of the two steel cages, thereby realizing the collinear docking of the upper and lower groups of steel cages.

[0069] Specifically, the angle range of the rotation connection between the first rotating rod 8001 and the second rotating rod 8003 is set to 90 degrees to 120 degrees. When the angle between the rotation connection between the first rotating rod 8001 and the second rotating rod 8003 is 90 degrees, the connection between the two second rotating rods 8003 and the clamps 8004 is in a horizontal state. At this time, the two clamps 8004 can completely fit the steel bar side walls of the steel cage, ensuring that the clamps 8004 and the steel bars of the steel cage fit together to the maximum extent; when the angle between the rotation connection between the first rotating rod 8001 and the second rotating rod 8003 is 120 degrees, the movable plate 7 is in a state closest to the fixed seat 6. At this time, the two clamps 8004 are in the maximum openness, so that when the subsequent equipment detaches from the steel bars of the steel cage, the two clamps 8004 opened at a sufficient angle can smoothly detach from the steel bars of the steel cage, avoiding the situation where the clamps 8004 cannot detach due to too small an opening angle.

[0070] Main references Figure 3 and Figure 6As shown, a driving unit for driving the first rotating seat 1003 and the second rotating seat 1004 to rotate is provided at the first rotating seat 1003 and the second rotating seat 1004; the driving unit includes a fixed platform 17, a cylinder 10 is fixedly installed on the fixed platform 17, a spur rack 11 is connected to the output end of the cylinder 10, a rotating shaft 12 is rotatably connected to the fixed platform 17 through a bearing, a gear 13 is fixedly installed on the rotating shaft 12, and the spur rack 11 is meshed and connected with the left side wall of the gear 13, an arc-shaped rack 14 is installed on the side wall of the first rotating seat 1003, and the first rotating seat 1003 is meshed and connected with the right side wall of the gear 13; wherein, a through groove for the gear 13 to rotate is opened on the side wall of the first fixed seat 1001;

[0071] The opened cylinder 10 causes the spur rack 11 to move, thereby causing the gear 13 meshing with the spur rack 11 to rotate. The rotation of the gear 13 drives the arc rack 14 to rotate circumferentially, thereby causing the first rotating seat 1003 and the second rotating seat 1004 to rotate relative to the first fixed seat 1001 and the first fixed seat 1002 respectively.

[0081] The present invention also provides a method for butt jointing a reinforcement cage butt jointing device, comprising the following steps:

[0082] S1. Equipment adjustment:

[0083] Move the docking device to the rear side of the steel cage, and make the first fixed seat 1001 and the first fixed seat 1002 in the separated state be located on the left and right sides of the steel cage respectively, so as to adjust the initial position of the device;

[0084] S2. Equipment weight:

[0085] The driving hand wheel 37 rotates to drive the screw rod 36 to rotate, and the screw rod 36 moves downward under the limiting action of the lifting column 34 until the bottom plate 35 is adjusted to fit the ground, and a counterweight block of appropriate weight is placed on the bottom plate 35;

[0086] S3. docking the first fixed seat 1001 with the first fixed seat 1002, the first rotating seat 1003 with the second rotating seat 1004:

[0087] By means of docking of two sets of positioning components, the first fixed seat 1001 and the first fixed seat 1002, the first rotating seat 1003 and the second rotating seat 1004 are docked respectively, so that the first fixed seat 1001 is connected with the first fixed seat 1002 to form an annular seat with a hollow annular space, and the first rotating seat 1003 and the second rotating seat 1004 are connected to form an annular plate. When the second rotating seat 1004 and the first fixed seat 1002 move to the left to gradually fit the first rotating seat 1003 and the first fixed seat 1001, the U-shaped plug 32 installed on the side walls of the second rotating seat 1004 and the first fixed seat 1002 can be inserted into the corresponding position. The inner cavity of the slot 28 is arranged, and the ball 31 is embedded in the inner cavity of the U-shaped plug block 32 by means of the elastic force of the spring 30. At this time, the ball 31 is locked in the U-shaped plug block 32, thereby realizing the locking connection of the first fixed seat 1001 and the first fixed seat 1002, the first rotating seat 1003 and the second rotating seat 1004 after docking, so as to ensure that the first fixed seat 1001 and the first fixed seat 1002 form an annular whole, and ensure that the first rotating seat 1003 and the second rotating seat 1004 after the locking connection can rotate synchronously under the action of external force, and at this time, the steel cage is located in the middle of the annular seat formed by the first fixed seat 1001 and the first fixed seat 1002;

[0088] S4. Preliminary connection of upper and lower reinforcement cages:

[0089] By means of a lifting device, the upper steel cage is lifted to the top of the steel cage inside the first fixing seat 1001 and the first fixing seat 1002, and the steel bars of the upper steel cage are positioned between the two clamping jaws 8004 above the movable plate 7, and the steel bars of the lower steel cage are positioned between the two clamping jaws 8004 below the movable plate 7;

[0090] S5. Upper and lower reinforcement cages are connected in line:

[0091] The docking unit causes each set of clamping jaws 8004 corresponding to the upper and lower positions of all movable plates 7 to rotate synchronously toward the middle, so as to clamp and limit the steel bars of the upper and lower steel cages respectively, so as to achieve the co-linear docking of the steel bars of the upper and lower steel cages:

[0092] The upper set of clamping jaws 8004 clamps and positions the steel bars of the upper steel cage, and the lower set of clamping jaws 8004 clamps and positions the steel bars of the lower steel cage. In addition, since the upper and lower sets of clamping jaws 8004 are arranged correspondingly, and the upper and lower sets of clamping jaws 8004 are synchronously driven by the moving plate 7, the synchronous clamping and positioning of the steel bars at the upper and lower steel cages can be achieved, and the two steel cages after positioning are ensured to be collinear. After positioning, the existing connecting sleeve is threadedly sleeved on the steel bar connection of the two steel cages, thereby achieving the collinear docking of the upper and lower sets of steel cages.

[0093] S6. Connect the upper and lower reinforcement cages after collinear docking:

[0094] The existing connection sleeve is threadedly sleeved on the steel bar connection of the two steel bar cages, thereby realizing the collinear connection of the upper and lower sets of steel bar cages;

[0095] S7. Remove the docking device from the steel cage.

[0096] It is worth noting that the cylinder 10 used in the present application is a self-locking cylinder commonly used on the market, and its output end can stay at any position and be locked; the motor 26 adopts a self-locking motor commonly used on the market with an output end that can be locked. When it stops working, the output end can be self-locked and will not rotate under external force, and the motor 26 is a forward and reverse motor commonly used on the market, and its output end can rotate forward or reverse according to usage requirements, and it can meet the above-mentioned usage requirements; the above-mentioned existing components will not be described in detail here.

[0097] The working principle of a reinforcement cage docking device and a docking method thereof in this embodiment is as follows:

[0098] First, adjust the position of the equipment, and install and connect the first fixing seat 1001 and the first fixing seat 1002: in the initial state, the first fixing seat 1001 and the first fixing seat 1002 are separated, move the equipment to the rear side of the steel cage, and gradually move the equipment to the front side, so that the steel cage is located in the first fixing seat 1001;

[0099] Secondly, the equipment is counterweighted to ensure the subsequent stability of the equipment: the hand wheel 37 is driven to rotate to drive the screw 36 to rotate, and the screw 36 moves downward under the limiting action of the lifting column 34 until the bottom plate 35 is in contact with the ground, and the counterweight block is placed on the bottom plate 35 to achieve the balance of the equipment;

[0100] Then, the first fixed seat 1001 and the first fixed seat 1002, the first rotating seat 1003 and the second rotating seat 1004 are locked and connected: the lead screw 25 is driven to rotate by the turned-on motor 26, so that the slider 23 threadedly mounted on the lead screw 25 moves to the left along the light rod 27, so as to cause the movable arm 22, the supporting platform 21 and the first fixed seat 1002 and the second rotating seat 1004 in the supporting platform 21 to move to the left synchronously; when the second rotating seat 1004 and the first fixed seat 1002 move to the left until they gradually fit the first rotating seat 1003 and the first fixed seat 1001, the U-shaped plug 32 installed on the side walls of the second rotating seat 1004 and the first fixed seat 1002 can be inserted into the inner cavity of the slot 28 at the corresponding position; during the process of the U-shaped plug 32 being inserted into the inner cavity of the slot 28 The U-shaped plug 32 first touches the ball 31 and forces the ball 31 to move upward, forcing the positioning rod 29 to move upward. At this time, the spring 30 is forced to stretch. When the U-shaped plug 32 is completely embedded in the inner cavity of the slot 28, the elastic force of the spring 30 causes the positioning rod 29 and the ball 31 to move downward synchronously, so that the ball 31 is embedded in the inner cavity of the U-shaped plug 32. At this time, the ball 31 is locked in the U-shaped plug 32, thereby realizing the locking connection between the first fixed seat 1001 and the first fixed seat 1002, the first rotating seat 1003 and the second rotating seat 1004 after docking, so as to ensure that the first fixed seat 1001 and the first fixed seat 1002 form an annular whole, and ensure that the first rotating seat 1003 and the second rotating seat 1004 after the locking connection can rotate synchronously under the action of external force;

[0101] Finally, each group of clamping jaws 8004 is driven to rotate synchronously toward the middle to limit the docking of the steel cage: the straight rack 11 is prompted to move by the opened cylinder 10 to prompt the gear 13 meshing with the straight rack 11 to rotate, and the rotation of the gear 13 drives the arc rack 14 to rotate circumferentially, so as to prompt the first rotating seat 1003 and the second rotating seat 1004 to rotate relative to the first fixed seat 1001 and the first fixed seat 1002 respectively. During the conversion process of the first rotating seat 1003 and the second rotating seat 1004, the moving frame 16 installed thereon slides and moves along the inner cavity of the limiting rod 15, and the movement of the first rotating seat 1003 and the second rotating seat 1004 is circumferentially limited by the moving frame 16 moving along the inner cavity of the limiting rod 15; with the rotation of the first rotating seat 1003, the moving pin 3 embedded in the sliding driving groove 2 is forced to move along the inner cavity of the driving groove 2, and the moving pin 3 brings The movable frame 5 moves synchronously toward the middle of the equipment to drive the movable plate 7 to move synchronously toward the middle of the equipment. The movement of the movable plate 7 drives the upper and lower groups of first rotating rods 8001 to respectively drive the upper and lower groups of second rotating rods 8003 to rotate synchronously relative to each other, so as to realize the upper and lower groups of clamps 8004 to rotate synchronously relative to each other; the upper group of clamps 8004 clamps and positions the steel bars of the upper steel cage, and the lower group of clamps 8004 clamps and positions the steel bars of the lower steel cage. In addition, since the upper and lower groups of clamps 8004 are arranged correspondingly up and down, and the upper and lower groups of clamps 8004 are synchronously driven by the movable plate 7, the synchronous clamping and positioning of the steel bars at the upper and lower steel cages can be realized, and the two steel cages after positioning are ensured to be collinear up and down. After positioning, the existing connecting sleeve is threadedly sleeved on the steel bar connection of the two steel cages, thereby realizing the collinear docking of the upper and lower groups of steel cages;

[0102] The present invention can quickly position the upper and lower steel cages, ensuring that the two steel cages can be aligned in the same line after docking, so as to facilitate the precise docking of the connecting sleeves at the docking point of the two steel cages. Compared with the method of repeated manual adjustment, it is more accurate and effectively avoids the problem of angle deviation and horizontal offset of the two steel cages caused by manual adjustment. In addition, all the upper and lower corresponding clamps 8004 are synchronously clamped toward the middle or unfolded toward the outside, that is, the upper and lower steel cages can be docked at all circumferential angles at one time. Compared with the traditional method of manually adjusting the docking angles one by one, it is more efficient, effectively shortens the project progress and improves the construction efficiency. In addition, the docking device adopts a split design, and the device can be assembled on the side wall of the steel cage from the side. Compared with the traditional method of using lifting equipment to sleeve the docking device from top to bottom on the side wall of the steel cage, the operation is more convenient, saves the cumbersome steps of operating the lifting equipment, and avoids the problem of limited steel cage docking construction due to limited use of lifting equipment.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

Equipment weight: The bottom plate (35) is adjusted to fit the ground, and a counterweight block of appropriate weight is placed on the bottom plate (35); S3. docking the first fixed seat (1001) with the first fixed seat (1002), the first rotating seat (1003) with the second rotating seat (1004): By means of docking of the two sets of positioning components, the first fixed seat (1001) and the first fixed seat (1002), and the first rotating seat (1003) and the second rotating seat (1004) are docked respectively, so that the first fixed seat (1001) and the first fixed seat (1002) are connected to form an annular seat with a hollow annular space, and the first rotating seat (1003) and the second rotating seat (1004) are connected to form an annular plate, and at this time, the steel cage is located in the middle of the annular seat formed by the first fixed seat (1001) and the first fixed seat (1002); S4. Preliminary connection of upper and lower reinforcement cages: By means of a lifting device, the upper steel cage is lifted to the top of the steel cage inside the first fixed seat (1001) and the first fixed seat (1002), and the steel bars of the upper steel cage are positioned between the two clamping claws (8004) above the movable plate (7), and the steel bars of the lower steel cage are positioned between the two clamping claws (8004) below the movable plate (7); S5. Upper and lower reinforcement cages are connected in line: The docking unit causes each group of clamping claws (8004) corresponding to the upper and lower parts of all movable plates (7) to rotate synchronously toward the middle, so as to clamp and limit the steel bars of the upper and lower steel cages respectively, thereby achieving the co-linear docking of the steel bars of the upper and lower steel cages; S6. Connect the upper and lower reinforcement cages after collinear docking: The existing connection sleeve is threadedly sleeved on the steel bar connection of the two steel bar cages, thereby realizing the collinear connection of the upper and lower sets of steel bar cages; S7. Remove the docking device from the steel cage.
