Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction of bite pile, in particular to a bite pile construction positioning and deviation rectification device. BACKGROUND

[0002] The bite pile is a kind of foundation pit enclosure structure formed by mutual bite arrangement between piles. The arrangement of the piles is that one is a non-reinforced super-retarding concrete pile (A pile) and the other is a reinforced concrete pile (B pile) (constructed by full casing drill), which are arranged at intervals. During construction, the A pile is constructed first, and then the B pile is constructed, and the construction of the B pile is completed after the initial setting of the A pile concrete and before the final setting. Both the A pile and the B pile are constructed by full casing drill, and the concrete of the intersecting part of the adjacent A pile is cut off, so as to realize bite. Before the construction step of pouring concrete, a reinforcement cage needs to be placed inside the steel casing, and the position of the reinforcement cage needs to be corrected before pouring to avoid the reinforcement cage from being skewed or twisted. Therefore, during construction, the positioning lug at the top of the reinforcement cage needs to be connected with a lifting device, and after adjusting the position of the reinforcement cage, the lifting device is used to directly adjust the reinforcement cage. Since the reinforcement cage is located inside the steel casing, it is not convenient to observe, which may lead to inaccurate positioning and deviation rectification of the reinforcement cage, and secondary deviation rectification is needed, thereby reducing the efficiency of deviation rectification.

[0008] Further, the moving unit comprises a second hydraulic cylinder, one end of the second hydraulic cylinder is rotationally connected to the inner side of one end of the first branch arm, a sliding frame is slidably connected to the inner side of the other end of the first branch arm, a push rod is rotationally connected to the top end of the sliding frame in the inverted T-shaped structure, the output end of the second hydraulic cylinder is rotationally connected to one side of the push rod, the second hydraulic cylinder pushes the push rod to be in a vertical state, then the push rod and the sliding frame move as a whole, and after the push rod contacts the reinforcement cage, the reinforcement cage can be in a central position due to the same moving distance of the plurality of push rods under the continuous pushing of the push rod.

[0009] Further, a rubber sheet in contact with the sliding frame is fixed to the inner side wall of the other end of the first branch arm, the rubber sheet and the sliding frame are in contact, the push rod is first pushed to be in a vertical state when the second hydraulic cylinder is just started, and then the sliding frame is moved, so that when the size of the reinforcement cage is small, the push rod is in a vertical state after the sliding frame moves to the outer side of the reinforcement cage, and the position of the reinforcement cage cannot be corrected.

[0010] Further, the two sides of the main plate are rotationally connected with side plates, and one side of the main plate is symmetrically rotationally connected with two first electric push rods, the output ends of the two first electric push rods are rotationally connected with adjacent side plates, the rotation angle of the two side plates relative to the main plate can be adjusted by the first electric push rods, so that the end of the side plate is extruded and abuts against the outer wall of the steel casing, and the vertical rod is in abutment with the inner wall of the steel casing, so that the whole bearing mechanism is stably placed at the top opening of the steel casing, and operation is facilitated.

[0011] Further, the inner side of the winding seat is fixed with a second electric push rod, and the output end of the second electric push rod abuts against the inner wall of the winding seat when the second electric push rod is in the working position.

[0014] Further, the side wall of the shell is fixed with a wire clamp, the wire clamp can store the pull rope connected to the wire hanging frame on the bottom surface of the shell inside, and avoid the pull rope from being entangled with the adjacent centering mechanism to cause normal use.

[0015] The beneficial effects of the present application are:

[0016] 1. By installing hanging frames and winding seats at the top and bottom of the housing, and by releasing the pull ropes that pass over the second electric push rod on the winding seat when it retracts, the centering mechanism can be manually pulled to move the two pull ropes separately when the centering mechanism gets tangled with the rebar cage during the overall upward movement of the drive mechanism and centering mechanism. This allows for adjustment of the housing's tilt angle by pulling the two pull ropes at different strokes. The tilted housing facilitates the adjustment of the position of the centering mechanism connected to the rebar cage, enabling the centering mechanism to detach from the rebar cage and facilitating overall lifting and recovery. This reduces the likelihood of the drive mechanism and centering mechanism being difficult to remove due to the rebar cage obstructing the movement, thus improving the efficiency of positioning and correction. Furthermore, by rotating the lead screw driven by the motor, the centering mechanism can be adjusted to a conical or inverted conical shape, further reducing the likelihood of the centering mechanism getting tangled with the rebar cage.

[0017] 2. By rotating and connecting the side plates on both sides of the main board, and connecting the main board and the side plates through the first electric push rod, the rotation angle of the side plates relative to the main board can be adjusted by the first electric push rod. After the horizontal plate overlaps the top opening of the steel casing, the output end of the first electric push rod pushes the side plate to fit tightly against the outer wall of the steel casing, which can improve the stability of the main board, cantilever and electric winch, and improve the efficiency of correction.

[0018] 3. By setting up a centering mechanism arranged in a cross shape, with two mechanisms distributed at different heights, the centering efficiency is improved after the centering mechanism contacts the side wall of the steel casing. This avoids errors in the correction of the reinforcing cage caused by the overall tilt of the casing. Furthermore, after the second hydraulic cylinder pushes the push rod vertically, it moves the sliding frame and push rod synchronously. After the push rod contacts the reinforcing cage, because multiple push rods move the same distance, the reinforcing cage can be centered under the continuous push of the push rod. The rubber sheet is set to contact the sliding frame, which can push the push rod vertically or horizontally first when the second hydraulic cylinder is started. This avoids the situation where the push rod is only vertical after the sliding frame has moved to the outside of the reinforcing cage, which would prevent the position of the reinforcing cage from being corrected. This design is applicable to reinforcing cages of different sizes and is convenient to use. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-9 As shown, a positioning and correction device for interlocking pile construction includes a bearing mechanism 100, a driving mechanism 200, and four centering mechanisms 300 arranged in a cross shape. The bearing mechanism 100 includes a main plate 110 and a top plate 130 fixed to the top of the main plate 110. Two horizontal plates 140 are symmetrically fixed at both ends of the top surface of the main plate 110, and vertical rods 150 are fixed to the bottom surface of the two horizontal plates 140. A cantilever 400 and an electric winch 500 for winding the pull rope are fixed to the top surface of the top plate 130.

[0030] The drive mechanism 200 includes a housing 210. Four rectangular through holes 211 are evenly distributed on the side wall of the housing 210. A lead screw 260 is rotatably connected to the center of the inner bottom surface of the housing 210. A fixing bracket 250 is fixed to the inner side of the housing 210, and a motor 240 is mounted on the top surface of the fixing bracket 250. The motor shaft of the motor 240 is fixed to the top end of the lead screw 260. A threaded sleeve 270 is screwed onto the lead screw 260, and connecting discs 271 penetrating the lead screw 260 are fixed to both ends of the threaded sleeve 270. Two sliding through holes 272 are symmetrically distributed on the connecting discs 271. A wire hanger 220 is fixed to one side of the top surface and the center of the bottom surface of the housing 210, and a pull rope is fixed to each of the two wire hangers 220. A winding seat 230 is fixed to one side of the wire hanger 220 on the top surface of the housing 210. One end of one pull rope passes over the end of the cantilever 400 and is fixed to the electric winch 500, and one end of the other pull rope passes over the winding seat 230 and the end of the cantilever 400 and is fixed to the electric winch 500. One end of the centering mechanism 300 is rotatably connected to a sliding through hole 272 at a corresponding position. The centering mechanism 300 is arranged inside a rectangular through hole 211 at a corresponding position. In use, the horizontal plate 140 on the main board 110 is attached to the top of the steel casing. At this time, the main board 110 is located outside the steel casing, and the vertical rod 150 is located inside the steel casing. The end of the cantilever 400 is adjusted to be located at the center of the steel casing. Then, the drive mechanism 200 and the centering mechanism 300 are lowered by releasing the pull rope through the electric winch 500. After being released to the appropriate position, the electric winch 500 stops releasing. The centering mechanism 300 is used to correct the position of the rebar cage. After the rebar cage is restored to verticality, positioning lugs can be added directly to the top of the rebar cage for connection. Multiple positioning lugs are used to keep the position of the rebar cage fixed. After the correction is completed, the electric winch 500 is used to wind up the rope to drive the drive mechanism 200 and the centering mechanism 300 to move upward. When the centering mechanism 300 is connected to the rebar cage, the winding seat 230 can be disengaged from the rope. Then, the workers adjust the movement of the two ropes separately to change the tilt angle of the shell 210 until the centering mechanism 300 can be disengaged from the rebar cage, which facilitates the overall lifting and recovery. This reduces the probability that the drive mechanism 200 and the centering mechanism 300 will be difficult to remove due to the obstruction of the rebar cage.

[0031] Specifically, rotating shafts 213 are fixed on both sides of the rectangular through hole 211 on the inner wall of the housing 210. First sliding grooves 273 are provided on both inner walls of the sliding through hole 272. The centering mechanism 300 includes a first arm 310. Second sliding grooves 311 are provided on both sides of the first arm 310, slidably connected to an adjacent rotating shaft 213. One end of the first arm 310 is fixed with a sliding shaft, and both ends of the sliding shaft are slidably connected to the inner side of a corresponding first sliding groove 273. The other end of the first arm 310 is slidably sleeved with a second arm 320, and the top surface of the second arm 320 is flush with... A first hydraulic cylinder 330 is fixed between the top surfaces of the first arm 310 and the first arm 310. A moving unit for pushing the rebar cage is provided on the inner side of the first arm 310. When the drive mechanism 200 moves downward, the motor 240 drives the lead screw 260 to rotate clockwise. The lead screw 260 causes the threaded sleeve 270 to move downward. At this time, because the end of the centering mechanism 300 is connected to the threaded sleeve 270, the centering mechanism 300, under the action of the rotating shaft 213, will have one end inside the housing 210 move downward, and the other end outside the housing 210 rotate upward, causing the entire drive mechanism 200 and centering mechanism 300 to move downward in a conical shape, enabling rapid... The rapid downward movement reduces the likelihood of the centering mechanism 300 becoming entangled with the rebar cage. Furthermore, when the drive mechanism 200 moves the centering mechanism 300 upward, the motor 240 reverses the lead screw 260, causing the threaded sleeve 270 to move upward, resulting in the centering mechanism 300 rotating downward. This allows the drive mechanism 200 and the centering mechanism 300 to move upward in an inverted cone shape, further reducing the likelihood of the centering mechanism 300 becoming entangled with the rebar cage. Additionally, the contact between the moving unit and the rebar cage allows for the correction of the rebar cage's position. The bottom surface of the second support arm 320 has a through hole, the width of which is greater than the width of the push rod 360. When the second hydraulic cylinder 340 pushes the sliding frame 350 to move, the push rod 360 is in a vertical state. Continuously pushing the sliding frame 350 to drive the push rod 360 to move can correct the deviation of the rebar cage. When the push rod 360 moves out of the range of the first support arm 310, the push rod 360 can move inside the through hole, so that it can be used for rebar cages with different inner diameters and is convenient to use. A wire clip 212 is fixed on the side wall of the housing 210. The wire clip 212 can be used to store the pull rope connected to the wire hanging frame 220 on the bottom surface of the housing 210 inside it, and prevent the pull rope from getting tangled with the adjacent centering mechanism 300, which would prevent it from being used normally.

[0032] Specifically, the moving unit includes a second hydraulic cylinder 340. One end of the second hydraulic cylinder 340 is rotatably connected to the inner side of one end of the first support arm 310. A sliding frame 350 is slidably connected to the inner side of the other end of the first support arm 310. A push rod 360 is rotatably connected to the top of the inverted T-shaped sliding frame 350. The output end of the second hydraulic cylinder 340 is rotatably connected to one side of the push rod 360. The second hydraulic cylinder 340 pushes the push rod 360 to a vertical position, and then pushes the push rod 360 and the sliding frame 350 to move as a whole. After the push rod 360 contacts the reinforcing cage, due to multiple push rods... The rod 360 moves the same distance. With the continuous pushing of the push rod 360, the rebar cage can be in the center position. A rubber sheet that contacts the sliding frame 350 is fixed on the inner wall of the other end of the first arm 310. By utilizing the contact between the rubber sheet and the sliding frame 350, the push rod 360 can be pushed vertically first when the second hydraulic cylinder 340 is started, and then the sliding frame 350 can be moved. In this way, when the size of the rebar cage is small, it avoids the push rod 360 being in a vertical state only after the sliding frame 350 has moved to the outside of the rebar cage, which would make it impossible to correct the position of the rebar cage.

[0033] Specifically, both the main board 110 and the side plate 120 are arc-shaped plate structures, and the second support arm 320 is a cuboid shell 210 mechanism. The arc-shaped plate structure of the main board 110 and side plate 120 facilitates contact with the side wall of the steel casing. By setting the second support arm 320 to a rectangular tube shape, after the end of the second support arm 320 abuts against the inner side wall of the steel casing, it can help maintain the overall stability of the drive mechanism 200, facilitating the centering mechanism 300 to correct the rebar cage and improving the efficiency of correction. Side plates 120 are rotatably connected to both sides of the main board 110, and two first electric push rods 160 are symmetrically rotatably connected to one side of the main board 110. The output ends of the two first electric push rods 160 are rotatably connected to an adjacent side plate 120. The first electric push rods 160 can adjust the rotation angle of the two side plates 120 relative to the main board 110, thereby allowing the ends of the side plates 120 to press against the outer wall of the steel casing. Furthermore, the vertical rod 1... The 50 abuts against the inner wall of the steel casing, thus allowing the entire bearing mechanism 100 to be stably placed at the top of the steel casing, facilitating operation. A second electric push rod 231 is fixed to the inner side of the winding seat 230. When the second electric push rod 231 is in the working position, the output end of the second electric push rod 231 is close to the inner wall of the winding seat 230. When the centering mechanism 300 and the reinforcing cage are moved upward as a whole, the output end of the second electric push rod 231 can be retracted. At this time, one of the pull ropes around the winding seat 230 is released. When the two pull ropes are pulled manually to move them separately, since one pull rope is connected to the top of the housing 210 and the other pull rope is connected to the bottom of the housing 210, the tilt angle of the housing 210 can be adjusted, which facilitates the adjustment of the position of the centering mechanism 300 connected to the reinforcing cage, so that the centering mechanism 300 can be disengaged from the reinforcing cage, which is convenient for overall lifting and recovery.

[0034] Working principle: In use, the hoist first connects the positioning lugs at the top of the steel cage with a wire rope to lift the entire steel cage to the inside of the steel casing. Then, the entire cage is placed on one side of the steel casing. The horizontal plate 140 on the main plate 110 is overlapped with the top of the steel casing. A controller can be installed on the top plate 130 to control the start and stop of the first electric push rod 160, the second electric push rod 231 and the motor 240. At this time, the first electric push rod 160 starts and pushes the side plate 120 to rotate until it is in close contact with the outer wall of the steel casing, so that the vertical rod 150 touches the inner side of the steel casing to fix the position of the top plate 130. Then, the end of the cantilever 400 is adjusted to be in the center position of the steel casing.

[0035] When the drive mechanism 200 moves downward, the motor 240 drives the lead screw 260 to rotate forward, causing the threaded sleeve 270 to move downward. At this time, because the end of the centering mechanism 300 is connected to the threaded sleeve 270, the centering mechanism 300 will move downward at one end inside the housing 210 and rotate upward at the other end inside the housing 210 under the action of the rotating shaft 213, so that the entire drive mechanism 200 and the centering mechanism 300 move downward in a conical shape. Then, the electric winch 500 releases the pull rope to lower the drive mechanism 200 and the centering mechanism 300. After being released to the appropriate position, the electric winch 500 stops releasing, and the first hydraulic cylinder 330 pushes the second arm 320 to move along the first arm 310. The movement continues until the end of the second arm 320 contacts the inner wall of the steel casing. Since the four second arms 320 move the same distance, when the second arms 320 cannot move, the housing 210 is in the center of the steel casing. Then, the second hydraulic cylinder 340 pushes the push rod 360 to a vertical position, and then pushes the push rod 360 and the sliding frame 350 to move as a whole. After the push rod 360 contacts the steel cage, since the multiple push rods 360 move the same distance, the steel cage can be in a centered position under the continuous pushing of the push rod 360. At this time, a positioning lug can be added to the top of the steel cage, and a steel wire rope can be used to connect the positioning lug and the lifting device, thereby adjusting the entire steel cage to a vertical position.

[0036] After the positioning and correction are completed, the motor 240 first drives the lead screw 260 to reverse, and the threaded sleeve 270 moves upward, causing the centering mechanism 300 to rotate downward. This makes the drive mechanism 200 and the centering mechanism 300 form an inverted cone shape. Then, the electric winch 500 winds up the pull rope to drive the drive mechanism 200 and the centering mechanism 300 to move upward. During the upward movement, the first hydraulic cylinder 330 may become hooked with the rebar cage. At this time, the output end of the second electric push rod 231 retracts. At this time, one pull rope that passes around the winding seat 230 is released. When the two pull ropes are pulled manually to move them separately, since one pull rope is connected to the top of the housing 210 and the other pull rope is connected to the bottom of the housing 210, the tilt angle of the housing 210 can be adjusted, which facilitates the adjustment of the position of the centering mechanism 300 hooked with the rebar cage, so that the first hydraulic cylinder 330 can be disengaged from the rebar cage.
