Description

Technical Field

[0001] This application relates to the technical field of construction, and in particular to a device for correcting the deviation of a steel reinforcement cage. Background Technique

[0002] During the construction of bridges, culverts or high-rise buildings, according to requirements, it may be necessary to drive piles for the foundation. The method is to use a machine to punch holes and drill holes with a water mill, and the hole depth reaches the design requirements. Then, a steel reinforcement cage is lowered into the pile hole, and a conduit is inserted for concrete pouring. During the construction process, it is necessary to hoist and place the steel reinforcement cage into the pile hole. In order to ensure the construction quality of the pile body, it is necessary to place the steel reinforcement cage at the central position of the pile hole. The accurate placement of the steel reinforcement cage is crucial for ensuring the stability and safety of the building structure.

[0003] Regarding the above related technologies, the inventor believes that during the construction process, after the steel reinforcement cage is placed in the pile hole, it is necessary to observe and adjust the position of the steel reinforcement cage to the central position of the pile hole. However, this method has certain deviations and low efficiency, and cannot meet the construction requirements of fast and accurate pile foundations. Utility Model Content

[0004] In order to improve the production quality of pile foundations, this application provides a device for correcting the deviation of a steel reinforcement cage.

[0005] The device for correcting the deviation of a steel reinforcement cage provided by this application adopts the following technical solutions:

[0006] A device for correcting the deviation of a steel reinforcement cage includes a connecting bracket and a deviation correction assembly. The connecting bracket includes two parallel guide rods. The deviation correction assembly includes a driving hydraulic cylinder and a set of deviation correction rods. The driving hydraulic cylinder is connected between the two guide rods. A first sliding plate is slidably connected to the two guide rods in common. The output shaft of the driving hydraulic cylinder is in transmission connection with the first sliding plate. The set of deviation correction rods includes a first deviation correction rod and a second deviation correction rod. One end of the first deviation correction rod is rotatably connected to the first sliding plate. One end of the second deviation correction rod is connected to the end of the first deviation correction rod away from the first sliding plate, and the other end of the second deviation correction rod is rotatably connected to the guide rod.

[0007] By adopting the above technical solutions, during construction, the casing is placed in the corresponding pile hole, and the steel reinforcement cage is hoisted into the casing. Several sets of deviation correction devices are placed in the gap between the casing and the steel reinforcement cage. The driving hydraulic cylinders in several sets of deviation correction devices operate simultaneously, driving the connection point of the first deviation correction rod and the second deviation correction rod to rotate towards the direction close to the steel reinforcement cage. Several sets of deviation correction rods simultaneously squeeze the steel reinforcement cage, realizing the deviation correction of the steel reinforcement cage, and making the central axis of the steel reinforcement cage coincide with the central axis of the casing. Through the mutual cooperation of the connecting bracket and the deviation correction assembly, the deviation correction operation of the steel reinforcement cage is realized, and the effect of improving the production quality of pile foundations is achieved.

[0008] Optionally, two sets of deviation rectifying rod groups are arranged in parallel on the first sliding plate. The two sets of deviation rectifying rod groups are arranged in one-to-one correspondence with two guide rods. A linkage rod is rotatably connected between the rotating shafts of the first deviation rectifying rod and the second deviation rectifying rod in the two sets of deviation rectifying rod groups. An abutting arc plate is connected to the side of the linkage rod away from the guide rod.

[0009] By adopting the above technical solution, the setting of the abutting arc plate increases the contact area between the deviation rectifying component and the steel reinforcement cage, and reduces the possibility of damage to the deviation rectifying rod group during the deviation rectifying process.

[0010] Optionally, hanging handles are arranged at the tops of the guide rods.

[0011] By adopting the above technical solution, the setting of the hanging handles facilitates the operator to hang the device on the top edge of the casing.

[0012] Optionally, a clamping component is arranged on the connecting bracket. The clamping component includes a connecting plate, a first clamping plate, a mounting plate and a second clamping plate. The bottoms of the two hanging handles are simultaneously connected to the connecting plate. The guide rods are arranged in parallel with respect to the connecting plate. The first clamping plate is arranged in parallel on the side of the connecting plate close to the guide rod. A driving member for driving the first clamping plate to approach or move away from the guide rod is arranged on the connecting plate. The mounting plate is connected to the guide rod and is arranged in parallel with the connecting plate. The second clamping plate is arranged in parallel on the side of the mounting plate close to the connecting plate. A driving member for driving the second clamping plate to approach or move away from the connecting plate is arranged on the mounting plate.

[0013] By adopting the above technical solution, the hanging handles are hung on the top of the casing. The first clamping plate and the second clamping plate both move in the direction of approaching each other under the drive of the driving member until the casing is clamped, realizing the fixation of the device and reducing the possibility of the device tilting and shaking on the casing during the deviation rectifying process.

[0014] Optionally, the first deviation rectifying rod includes a sliding sleeve rod and an extension sliding rod slidably connected thereto. A positioning member for positioning the extension sliding rod is arranged on the sliding sleeve rod. The sliding sleeve rod is rotatably connected to the first sliding plate. The extension sliding rod is rotatably connected to the second deviation rectifying rod.

[0015] By adopting the above technical solution, the overall length of the first deviation rectifying rod is adjusted by adjusting the position of the extension sliding rod in the sliding sleeve rod, so that the device can be applied to steel reinforcement cages of different diameter specifications.

[0016] Optionally, a second sliding plate is rotatably connected to one end of the second deviation rectifying rod away from the first deviation rectifying rod. The second sliding plate is slidably sleeved on the guide rod, and a fastener for positioning the second sliding plate is arranged on the guide rod.

[0017] By adopting the above technical solution, for steel reinforcement cages with different diameters, the position of the second sliding plate on the guide rod is adjusted, and the second sliding plate is positioned by using the fastener, so that the deviation rectifying rod group can be applicable to steel reinforcement cages with different diameters.

[0018] Optionally, an installation sleeve rod perpendicular to the guide rod is arranged on one side of the abutting arc plate close to the guide rod. A sliding L-shaped rod is slidably arranged in the installation sleeve rod. One end of the sliding L-shaped rod extends out of the installation sleeve rod and is connected with a sliding sleeve, and the sliding sleeve is slidably sleeved on the guide rod.

[0019] By adopting the above technical solution, when the abutting arc plate moves along with the deviation rectifying rod group, relative sliding occurs between the installation sleeve rod and the sliding L-shaped rod, and the sliding sleeve slides on the guide rod. The setting of the sliding sleeve realizes the guiding of the abutting arc plate and also avoids the abutting arc plate driving the linkage rod to rotate.

[0020] Optionally, the sliding L-shaped rod includes a sliding section and a connecting section perpendicular to it. One end of the sliding section is slidably arranged in the installation sleeve rod. The connecting section is connected with the sliding sleeve, and scale lines are arranged on the sliding section along its length direction.

[0021] By adopting the above technical solution, when the abutting arc plate moves in the pile hole, the sliding section slides in the installation sleeve rod, and the setting of the scale lines enables the operator to intuitively observe the distance between the abutting arc plate and the inner wall of the casing.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the mutual cooperation of the connecting bracket and the deviation rectifying assembly, the deviation rectifying operation of the steel reinforcement cage is realized, and the effect of improving the production quality of the pile foundation is achieved;

[0024] 2. The setting of the abutting arc plate increases the contact area between the deviation rectifying assembly and the steel reinforcement cage, and reduces the possibility of damage to the deviation rectifying rod group during the deviation rectifying process;

[0025] 3. For steel reinforcement cages with different diameters, the position of the second sliding plate on the guide rod and the overall length of the first deviation rectifying rod are adjusted, so that the deviation rectifying rod group can be applicable to steel reinforcement cages with different diameters.

[0031] The following Figures 1-4 further elaborates on the present application in detail. The embodiment of the present application provides a steel reinforcement cage deviation rectification device, which has the effect of improving the production quality of pile foundations.

[0032] Referring to Figure 1 and Figure 2 , a steel reinforcement cage deviation rectification device includes a connecting bracket 1, a deviation rectification assembly 2, and a clamping assembly 3.

[0035] Refer to Figure 4 The second sliding plate 26 is slidably sleeved on the guide rod 101, and the second sliding plate 26 is arranged on the side of the first sliding plate 25 away from the driving hydraulic cylinder 21. The bottom end of the guide rod 101 is provided with a threaded section, and two fixing bolts 5 are threadedly connected to the threaded section of the guide rod 101. The second sliding plate 26 is clamped between the two fixing bolts 5. One end of the extended sliding rod 272 extends out of the sliding sleeve rod 271 and is rotatably connected to one end of the second deviation rectifying rod 28, and the other end of the second deviation rectifying rod 28 is rotatably connected to the second sliding plate 26.

[0036] Refer to Figure 4 On the side of the linkage rod 22 away from the guide rod 101, a connecting block 29 is arranged, and the side of the connecting block 29 away from the linkage rod 22 is connected to the abutting arc plate 23. On the side of the abutting arc plate 23 close to the guide rod 101, two mounting sleeve rods 6 are arranged, and a sliding L-shaped rod 7 is arranged on the mounting sleeve rods 6. The sliding L-shaped rod 7 includes a sliding section 71 arranged vertically and a connecting section 72. One end of the sliding section 71 is slidably arranged in the mounting sleeve rod 6. The sliding section 71 is arranged perpendicular to the guide rod 101, and scale lines 8 are arranged along the length direction of the sliding section 71. The end of the connecting section 72 away from the sliding section 71 is fixedly connected to a sliding sleeve 24, and the sliding sleeve 24 is slidably connected to the guide rod 101.

[0037] Refer to Figure 2 and Figure 3, the clamping assembly 3 is arranged on the connecting bracket 1. The clamping assembly 3 includes a connecting plate 31, a first clamping plate 32, a driving screw 33, a limiting rod 34, a limiting block 35, a rotating block 36, a mounting plate 37, a clamping cylinder 38 and a second clamping plate 39. The connecting plate 31 is connected to two hanging handles 102 at the same time. The connecting plate 31 is arranged in parallel with two guiding rods 101 at the same time. The first clamping plate 32 is arranged between the connecting plate 31 and the guiding rod 101. The driving screw 33 is threadedly connected to the connecting plate 31. One end of the driving screw 33 is rotatably connected to the first clamping plate 32, and the other end is connected to the rotating block 36. The limiting rod 34 slidably penetrates through the connecting plate 31 and is parallel to the driving screw 33. One end of the limiting rod 34 is connected to the connecting plate 31, and the other end is connected to the limiting block 35. A mounting plate 37 is connected to each guiding rod 101.

The output shaft of the clamping cylinder 38 extends towards the connecting plate 31 and is connected to the second clamping plate 39.

[0038] Refer to Figure 1 , Figure 2 and Figure 4 , during pile foundation construction, a casing is placed in the pile hole, and the steel reinforcement cage is hoisted into the casing using a hoisting device. Install no less than three sets of deviation correction devices on the casing, hang the hanging handle 102 on the edge of the casing, and rotate the rotating block 36. The first clamping plate 32 moves towards the direction close to the outer wall of the casing under the drive of the driving screw 33 and the guiding action of the limiting rod 34. At the same time, the clamping cylinder 38 is started, and the second clamping plate 39 moves towards the direction close to the inner wall of the casing under the drive of the clamping cylinder 38. The first clamping plate 32 and the second clamping plate 39 clamp the casing at the same time, realizing the positioning of the connecting bracket 1 and reducing the possibility of the connecting bracket 1 tilting and shaking on the casing during the deviation correction process.

[0039] Refer to Figure 2 and Figure 4 , after the fixing of the connecting bracket 1 is completed, the driving hydraulic cylinder 21 is started to drive the first sliding plate 25 to slide downward. The first deviation correction rod 27 and the second deviation correction rod 28 form a certain angle, and the abutting arc plates 23 arranged on the linkage rod 22 in several sets of deviation correction devices move towards the direction close to the central axis of the casing synchronously, realizing the deviation correction operation of the steel reinforcement cage. During the process of the abutting arc plate 23 moving towards the central axis of the casing, the sliding section 71 of the sliding L-shaped rod 7 slides in the mounting sleeve rod 6, and the sliding sleeve 24 slides on the guiding rod 101, realizing the limiting and guiding of the abutting arc plate 23. Through the scale line 8 on the sliding part, it can be directly observed whether the distances of each abutting arc plate 23 from the inner wall of the casing are the same, improving the accuracy of the deviation correction process.

[0040] Refer to Figure 2 andFigure 4 For steel reinforcement cages of different specifications, in order to enable the abutting arc plate 23 to contact the steel reinforcement cage, it is necessary to adjust the length of the first deviation rectifying rod 27 and the position of the second sliding plate 26 on the guiding rod 101. Adjust the position of the extension sliding rod 272 in the sliding sleeve rod 271, and use the locking bolt 4 to position the extension sliding rod 272. Rotate and tighten the fixing bolt 5 to adjust the position of the second sliding plate 26 on the guiding rod 101, and rotate and tighten the fixing bolt 5 to fix the second sliding plate 26. This enables the deviation rectifying assembly 2 to be applicable to the deviation rectifying operations of steel reinforcement cages of different specifications. The setting of the abutting arc plate 23 increases the contact area between the deviation rectifying assembly 2 and the steel reinforcement cage, reducing the possibility of damage to the deviation rectifying rod group.

[0041] In the embodiment of the present application, the implementation principle of a steel reinforcement cage deviation rectifying device is as follows: During pile foundation construction, a casing is placed in the pile hole, and the steel reinforcement cage is hoisted into the casing using a hoisting device. Install no less than three sets of deviation rectifying devices on the casing, and use the clamping assembly 3 to position the connecting bracket 1, reducing the possibility of the connecting bracket 1 tilting and shaking on the casing during the deviation rectifying process.
