[0002] The quality requirements for reinforced concrete structures are becoming increasingly higher. For the secondary lining concrete of the shaft constructed from bottom to top using the slipform construction process, surface cracks are not allowed. Taking measures to strictly control the position of the steel bars and the thickness of the steel bar protective layer of the reinforced concrete structure is an effective measure to reduce concrete cracks. Therefore, the steel bars need to be positioned during the secondary lining slipform construction to facilitate the staff to carry out subsequent work.

[0003] However, in the construction of the secondary lining slipform of some shafts, it is often necessary to manually measure and locate the distance between each steel bar and the inner wall of the shaft one by one. This not only consumes a lot of time, but also causes fatigue among the workers after a long period of measurement and positioning, which may lead to problems such as incorrect positioning. Moreover, this inefficient working method will delay the construction period. Summary of the invention

[0007] Preferably, a rotating groove is provided on the left side of the rotating rod, and a moving block 1 is rotatably connected to the inner wall of the rotating groove, a moving hole is provided on the front of the moving block 1, a fixing rod 1 is fixedly connected to the bottom of the rotating plate, the inner wall of the moving hole is in contact with the outer surface of the fixing rod 1, and a top block is fixedly connected to the right side of the moving block 1. After the device is installed on the crane as a whole through the assembly frame, a plurality of steel bars are installed on the device, and then the device as a whole is lowered to a position suitable for operation by the staff, and the motor is started to make the rotating column 1 drive the rotating plate as a whole to rotate counterclockwise through the fixing frame. Since the fixing plate 1 is fixedly connected to the bottom of the assembly frame, when the rotating plate as a whole rotates The rotation of the rotating rod will drive the moving block 1 to extend under the restriction of the fixed rod 1. Since the top block is fixed on the moving block 1, it will drive the top block to move synchronously when it moves, until the top block contacts the inner wall of the shaft, so that its outer wall is supported on the inner wall of the shaft, thereby fixing the device as a whole and making the device more stable, avoiding the shaking of the device when the staff performs subsequent operations on the steel bars, which will lead to inaccurate positioning of the distance between the steel bars and the inner wall of the shaft, affecting the construction.

[0008] Preferably, the number of positioning components is two, the two hydraulic telescopic cylinders are symmetrically arranged with the assembly frame as the center, the bottom of the hydraulic telescopic cylinder is fixedly connected to the top of the fixed ring, a hole groove is opened on the right side of the movable block 2, the inner wall of the hole groove contacts with an annular spring, and a limiting groove is opened on the temporal part of the telescopic column 1.

[0009] Preferably, there are several limit grooves, which are arranged in a horizontal array, the right side of telescopic column one is rotatably connected to rotating column two, the front thread of telescopic column one is connected to the limit thread, and a trapezoidal groove is opened on the top of moving block two.

[0010] Preferably, a clamping assembly is provided above the rotating plate, and the number of the clamping assemblies is several, and the parts contained in the several clamping assemblies are all the same. The clamping assembly includes a limit rod, which contacts the top of the second moving block, and the left side of the second moving block is fixedly connected to the second telescopic column, and the right side of the inner wall of the slot is fixedly connected to the tension spring, and the left side of the second telescopic column is fixedly connected to the front side of the inner wall of the slot.

[0011] Preferably, the right side of the tension spring is fixedly connected to one side of the telescopic column 2 close to the limit rod, the inner wall of the trapezoidal groove contacts the limit block, the top of the limit block is fixedly connected with a clamping claw, the left side of the clamping claw is slidably connected to the outer surface of the limit rod, there are two clamping claws, the two clamping claws are symmetrically arranged around the telescopic column 2, and the inner wall of the assembly hole is fixedly connected with an assembly claw 1. The present invention moves the moving block 2 by pressing down on the lower pressure ring. Since the top of the moving block 2 is provided with a trapezoidal groove, when it moves outward, the two limit blocks matched with it will drive the two clamping claws to move in relative directions, and the continuous movement will cause the two clamping claws to contact the assembly claws installed in advance. The steel bar on the first, because a tension spring is arranged on the back of the limit rod, and the tension spring is fixedly connected to the inner wall of the groove opened by the fixing ring, after the clamping claw clamps the steel bar and moves to the position where it cannot move further and is driven by the moving block two, the tension spring will generate a pulling force on the limit rod, so that the two clamping claws can clamp the steel bar more stably under the restriction of the trapezoidal groove. Under the continuous movement, the two clamping claws will also drive the steel bar to break away from the restriction of the assembly claw one, so that the device can be more stable when driving the steel bar for positioning, avoiding the hidden danger of the steel bar falling off when moving and positioning, and effectively protecting the work safety of the staff.

[0012] Preferably, a bending assembly is arranged under the rotating plate, and the number of the bending assemblies is several, and the several bending assemblies are arranged in a circular array, and the parts included in the several bending assemblies are the same. The bending assembly includes a fixed plate 2, the top of the fixed plate 2 is fixedly connected to the bottom of the rotating plate, the back of the fixed plate 2 is fixedly connected to a telescopic cylinder 1, the back of the telescopic cylinder 1 is fixedly connected to a connecting tube 2, and the side of the connecting tube 2 away from the telescopic cylinder 1 is fixedly connected to the telescopic cylinder 2.

[0013] Preferably, the top of the telescopic cylinder 2 away from the connecting tube 2 is rotatably connected with a rotating wheel rod, the top of the rotating wheel rod is fixedly connected to the limiting column, the bottom of the top block is fixedly connected to a connecting plate, the bottom of the connecting plate is provided with a slideway, the inner wall of the slideway is in contact with the outer surface of the limiting column, and the bottom of the connecting plate is fixedly connected with a second assembly claw, the number of the second assembly claws is two, and the two second assembly claws are symmetrically arranged. The present invention can make the telescopic cylinder 1 move in the direction of the fixed plate 2 away from the second fixed plate through the movement of the top block. Since the inside is full of liquid, the continuous movement will make the liquid inside enter the inside of the telescopic cylinder 2 through the connecting tube 2. The increase of liquid in the telescopic cylinder II will drive the two rotating wheel rods to move. Since a slideway adapted to the limit column is provided at the bottom of the connecting plate, the rotating wheel rod will rotate in the preset direction of the slideway when the telescopic cylinder II pushes the rotating wheel rod to move. The rotation of the two rotating wheel rods will push the steel bars fixed in advance on the two assembly claws II along the direction of the preset slideway, and bend them and fit them against the inner wall of the shaft, so that the steel bars and the vertical steel bars can be directly operated subsequently. Compared with the previous manual bending, it not only saves a lot of time, but also makes it more convenient for the staff to operate and reduces the workload of the staff.

[0014] The present invention has the following beneficial effects:

[0015] (1) According to the present invention, after a worker measures the distance between a steel bar and the inner wall of the shaft, the worker then turns the limiting thread to adjust the distance of the telescopic column 1. After the adjustment is completed, the worker turns the limiting thread in the opposite direction to fix the telescopic column 1. After the device is lowered as a whole to a position suitable for the worker to carry out construction, the motor is started to drive the rotating column 1 to rotate through the fixed frame. The rotation of the rotating plate will cause the top block to drive the hydraulic telescopic cylinder 1 on the fixed rod 2 to move. The movement of the hydraulic telescopic cylinder 1 will drive the telescopic column 1 to move synchronously. After the device is continuously extended, since the length of the telescopic column 1 is greater than the top block, the rotating column 2 will first contact the inner wall of the shaft. Under the continuous push of the top block, the telescopic column 1 will push the hydraulic telescopic cylinder 1 into the shaft. The movement of the hydraulic telescopic cylinder 1 will cause the liquid inside it to be transported into the hydraulic telescopic cylinder 2 through the connecting pipe 1. The increase of liquid in the hydraulic telescopic cylinder 2 will drive the push block to push toward the center of the device. Since the push block is arranged obliquely and fits with the lower pressure ring, it will push the lower pressure ring downward. The downwardly pushed lower pressure ring will push the moving block 2 matched with its bottom inclined surface under the restriction of the fixed ring. Since there are several positioning components, several steel bars can be driven to move at the same time, so that several steel bars can be positioned, which reduces the large amount of time spent on positioning the steel bars and speeds up the construction period. It can not only reduce the workload of the staff, but also avoid the problem of incorrect positioning caused by fatigue of the staff during positioning.

[0016] (2) The present invention installs the device as a whole on the crane through the assembly frame, and then installs a plurality of steel bars on the device. After the device as a whole is lowered to a position suitable for the staff to operate, the motor is started to drive the rotating column 1 to drive the rotating plate as a whole to rotate counterclockwise through the fixed frame. Since the fixed plate 1 is fixedly connected to the bottom of the assembly frame, the fixed plate 1 will not be driven to rotate when the rotating plate as a whole rotates. Since the fixed plate 1 is connected to the rotating plate through the rotating rod, the rotating plate will cause the rotating rod to rotate when it rotates counterclockwise. The rotation of the rotating rod will drive the moving block 1 to extend out under the restriction of the fixed rod 1. Since the top block is fixed on the moving block 1, it will drive the top block to move synchronously when it moves until the top block contacts the inner wall of the shaft, so that its outer wall is supported on the inner wall of the shaft, and the device as a whole is fixed to make the device more stable, so as to avoid the device shaking when the staff performs subsequent operations on the steel bars, thereby causing the distance positioning between the steel bars and the inner wall of the shaft to be inaccurate, affecting the construction.

[0017] (3) The present invention moves the moving block 2 by pressing down the lower pressure ring. Since a trapezoidal groove is provided on the top of the moving block 2, when the moving block 2 moves outward, two limit blocks matched with the moving block 2 will drive the two clamping claws to move in relative directions. Continuous movement will cause the two clamping claws to contact the steel bars installed in advance on the assembly claw 1. Since a tension spring is provided on the back of the limit rod, the tension spring is fixedly connected to the inner wall of the groove provided on the fixing ring. After the clamping claws clamp the steel bars and move to a position where they cannot move further and are driven by the moving block 2, the tension spring will generate a pulling force on the limit rod, so that the two clamping claws can clamp the steel bars more stably under the restriction of the trapezoidal groove. Under continuous movement, the two clamping claws will also drive the steel bars to break away from the restriction of the assembly claw 1, so that the device can be more stable when driving the steel bars for positioning, avoiding the hidden danger of the steel bars falling off when moving and positioning, and effectively protecting the work safety of the staff.

[0018] (4) The present invention causes the telescopic cylinder 1 to move away from the side of the fixed plate 2 toward the fixed plate 2 through the movement of the top block. Since the interior of the telescopic cylinder 1 is filled with liquid, the continuous movement causes the liquid inside the telescopic cylinder 2 to enter the interior of the telescopic cylinder 2 through the connecting pipe 2. The increase in liquid in the telescopic cylinder 2 causes the two rotating wheel rods to move. Since a slideway adapted to the limit column is provided at the bottom of the connecting plate, the rotating wheel rod will rotate in the preset direction of the slideway when the telescopic cylinder 2 pushes the rotating wheel rod to move. The rotation of the two rotating wheel rods will push the steel bars fixed in advance on the two assembly claws 2 along the preset direction of the slideway, and bend them so that they fit with the inner wall of the shaft, so that the steel bars and the vertical steel bars can be directly operated in the subsequent steps. Compared with the previous manual bending, it not only saves a lot of time, but also makes the operation more convenient for the staff, reducing the workload of the staff.

Since the inside is full of liquid, the continuous movement causes the liquid inside to pass through the connecting tube 2 512 After entering the interior of the telescopic cylinder 53, the increase of liquid in the telescopic cylinder 53 will drive the two rotating wheel rods 531 to move. Since a slideway adapted to the limit column 532 is provided at the bottom of the connecting plate 52, the rotating wheel rod 531 will rotate in the preset direction of the slideway when the telescopic cylinder 53 pushes the rotating wheel rod 531 to move. The rotation of the two rotating wheel rods 531 will push the steel bars fixed in advance on the two assembly claws 521 along the direction of the preset slideway, and bend them and fit them against the inner wall of the shaft, so that the steel bars and the vertical steel bars can be directly operated subsequently. Compared with the previous manual bending, it not only saves a lot of time, but also makes it more convenient for the staff to operate, reducing the workload of the staff.

[0041] A specific application of this embodiment is: after the device is installed on the crane as a whole through the assembly frame 1, a number of steel bars are installed on the device, and then the device is lowered to a position suitable for the staff to operate, the motor 13 is started to drive the rotating column 131 to drive the rotating plate 12 to rotate counterclockwise as a whole through the fixed frame 132. Since the fixed plate 11 is fixedly connected to the bottom of the assembly frame 1, when the rotating plate 12 rotates as a whole, it will not drive the fixed plate 11 to rotate. Since the fixed plate 11 is connected to the rotating plate 12 through the rotating rod 21, the rotating plate 12 is rotated. When the top block 212 is fixed on the moving block 211, it will drive the top block 212 to move synchronously when it moves, until the top block 212 contacts the inner wall of the shaft, so that its outer wall is supported on the inner wall of the shaft, and the device as a whole is fixed to make the device more stable, so as to avoid the device shaking when the staff performs subsequent operations on the steel bars, thereby causing the distance positioning between the steel bars and the inner wall of the shaft to be inaccurate, affecting the construction.

[0042] After the staff measures the distance between a steel bar and the inner wall of the shaft, they then turn the limiting thread 36 to adjust the distance of the telescopic column 135. After the adjustment is completed, they turn the limiting thread 36 in the opposite direction to fix the telescopic column 135. Then, after the device is lowered as a whole to a position suitable for the staff to carry out construction, the motor 13 is started to drive the rotating column 131 to rotate through the fixing frame 132. The rotation of the rotating plate 12 will cause the top block 212 to drive the hydraulic telescopic cylinder 132 on the fixed rod 231 to move. The movement of the hydraulic telescopic cylinder 132 will drive the telescopic column 135 to move synchronously. After the device is continuously extended, since the length of the telescopic column 135 is greater than the top block 212, the rotating column 1351 will first contact the inner wall of the shaft. Under the continuous push of the top block 212, the telescopic column 135 will push the hydraulic telescopic cylinder 13 2 moves in the opposite direction of the inner wall of the shaft. The movement of the hydraulic telescopic cylinder 1 32 will transport the liquid inside it into the hydraulic telescopic cylinder 2 33 through the connecting pipe 1 321. The increase of liquid in the hydraulic telescopic cylinder 2 33 will drive the push block 331 to push toward the center of the device. Since the push block 331 is arranged obliquely and fits with the lower pressure ring 34, it will push the lower pressure ring 34 downward. The downwardly pushed lower pressure ring 34 will push the moving block 2 341 adapted to its bottom inclined surface under the restriction of the fixed ring 121. Since there are several positioning components 3, several steel bars can be driven to move at the same time, so that several steel bars can be positioned, reducing the large amount of time spent on positioning the steel bars, speeding up the construction period, not only reducing the workload of the staff, but also avoiding the problem of incorrect positioning caused by fatigue of the staff during positioning.

[0043] The second moving block 341 is moved by pressing down the lower pressing ring 34. Since a trapezoidal groove is provided on the top of the second moving block 341, when it moves outward, the two stop blocks 412 matched with it drive the two clamping claws 411 to move in relative directions. The continuous movement makes the two clamping claws 411 contact the steel bars pre-installed on the assembly claw 1 43. Since a tension spring 421 is provided on the back of the stop rod 41, the tension spring 421 is fixedly connected to the inner wall of the notch provided on the fixing ring 121, the clamping claws 411 can be pressed against the steel bars. After the steel bar is clamped and moved to a position where it cannot move further and is driven by the moving block 2 341, the tension spring 421 will generate a pulling force on the limit rod 41, so that the two clamping claws 411 can clamp the steel bar more stably under the restriction of the trapezoidal groove. Under continuous movement, the two clamping claws 411 will also drive the steel bar to break away from the restriction of the assembly claw 1 43, so that the device can be more stable when driving the steel bar for positioning, avoiding the hidden danger of the steel bar falling off when moving and positioning, and effectively protecting the work safety of the staff.

[0044] The movement of the top block 212 will cause the telescopic cylinder 1 511 to move away from one side of the fixed plate 2 51 toward the fixed plate 2 51. Since the interior of the telescopic cylinder 1 511 is filled with liquid, the continuous movement will cause the liquid inside to enter the interior of the telescopic cylinder 2 53 through the connecting pipe 2 512. The increase of liquid in the telescopic cylinder 2 53 will drive the two rotating wheel rods 531 to move. Since a slideway adapted to the limiting column 532 is provided at the bottom of the connecting plate 52, the rotating wheel rod 531 will rotate in the preset direction of the slideway when the telescopic cylinder 2 53 pushes the rotating wheel rod 531 to move. The rotation of the two rotating wheel rods 531 will push the steel bars fixed in advance on the two assembly claws 2 521 along the direction of the preset slideway, and bend it and fit it against the inner wall of the shaft, so that the steel bars and the vertical steel bars can be directly operated subsequently. Compared with the previous manual bending, it not only saves a lot of time, but also makes the operation more convenient for the staff and reduces the workload of the staff.
