Description

Technical Field

[0001] This utility model patent relates to the technical field of pile foundation engineering, and more specifically, to a temporary support bracket for pipe pile construction with adjustable inclination angle. Background Technology

[0002] Temporary support frames for pipe pile construction are important auxiliary equipment in civil engineering and building construction. They are mainly used to provide temporary support, positioning, and angle adjustment during the construction of pipe piles (such as prestressed concrete pipe piles, steel pipe piles, etc.) to ensure construction accuracy, safety, and efficiency.

[0003] In existing pipe pile construction processes, pipe piles are erected by hoisting and then installed using vibratory driving or static pressure methods. However, there are certain limitations on the installation angle and stability. During vibratory driving, it is difficult to control the position of the pipe pile due to swaying when it is hoisted, and it mainly relies on simple support devices, which are easily affected by operational errors. During the swaying process, it is easy to hit construction personnel and cause safety accidents, posing a high construction risk. On the other hand, static pressure requires large support equipment and cannot adjust the installation angle. When the construction requirement is inclined piling, the existing supports cannot be placed stably on the inclined installation surface, and cannot achieve stable support. At the same time, in cases where there are buildings or large protrusions next to the piling location, static pressure installation support cannot be installed at the piling location.

[0034] Reference Figure 1-8 The image shown is a preferred embodiment of the present invention.

[0035] An adjustable-angle temporary support frame for pipe pile construction includes a base plate 1, a support component 3 on top of the base plate 1, a counterweight box 2 at the rear and sides of the support component 3, and a clamping structure 4 at the front end above the support component 3.

[0036] The adjustable tilt angle temporary support for pipe pile construction provided in this embodiment uses a base plate 1 to support the overall support and increase the grounding area. In order to adapt to different construction environments, the equipment can be placed on a vehicle or movable brake casters can be added to the bottom of the base plate 1.

[0037] The support component 3 can be set to allow the mechanical control of the support frame to adjust the front and rear angles of the pile body by tilting it forward and backward.

[0038] The counterweight box 2 can be used to place heavy objects to balance the support frame and prevent it from tipping over.

[0039] The clamping structure 4 allows the support frame to mechanically control the clamping of the pipe pile and adjust the left and right angles of the pile body.

[0040] In this embodiment, the support component 3 includes a first fixed base 301, a support column 302 is hinged above the first fixed base 301, and a second fixed base 305 is provided behind the first fixed base 301. The first fixed base 301 and the second fixed base 305 are fixedly connected to the base plate 1. By hinged between the first fixed base 301 and the support column 302, the support column 302 can tilt back and forth and be fixed as a whole on the base plate 1.

[0041] In this embodiment, the front end of the support column 302 is provided with a movable groove 303, and the rear end of the support column 302 is provided with a third fixed base 306. A second hydraulic rod 307 is provided between the second fixed base 305 and the third fixed base 306. The two ends of the second hydraulic rod 307 are respectively hinged to the second fixed base 305 and the third fixed base 306. By fixing the third fixed base 306 to the rear of the support column 302 and hinged the second hydraulic rod 307 between the second fixed base 305 and the third fixed base 306, the movement of the support column 302 can be mechanically controlled to adjust the tilt angle of the pipe pile clamped by the clamping structure 4, which is used to adjust the tilt angle of the pipe pile.

[0042] In this embodiment, a hydraulic rod 304 is fixedly provided at the bottom end of the movable groove 303, and a fixed rod 308 is provided behind the hydraulic rod 304. The two ends of the fixed rod 308 are fixedly connected to the bottom end and the top end of the movable groove 303. By extending and retracting the hydraulic rod 304, the clamping structure 4 can be controlled to move up and down and control the height. This is used to cooperate with the clamping structure 4 to move down to clamp the pipe pile and lift it up to adjust the angle. After the angle is adjusted, the clamping structure 4 moves down again to place the pipe pile on the ground and fix it.

[0043] In this embodiment, the clamping structure 4 includes a movable support column 401, which is sleeved on the fixed rod 308. A rotating disk 402 is fixedly provided at the front end of the movable support column 401, and a mechanical claw assembly 5 is provided at the front end of the rotating disk 402. The movable support column 401 is sleeved on the fixed rod 308 to prevent the clamping structure 4 from shifting and getting stuck when moving up and down.

[0044] The rotating disk 402 is fixed to the rotating shaft of the motor, which is fixed inside the movable support column 401. The motor drives the rotating disk 402 to rotate, controlling the mechanical claw assembly 5 to rotate left and right, adjusting the left and right tilt angle of the pile body, which is used to adjust the tilt angle of the pipe pile.

[0045] In this embodiment, the mechanical claw assembly 5 includes a fixing block 501. The rear end of the fixing block 501 is fixedly connected to the front end of the rotating disk 402. Grooves are provided on the front and rear sides of both sides of the fixing block 501. A fourth fixing base 502 is fixedly provided at the rear end of the groove on both sides of the fixing block 501. A rotating shaft 503 is rotatably provided in the groove at the front end of the fixing block 501. The upper and lower ends of the rotating shaft 503 pass through the upper and lower ends of the groove on both sides of the fixing block 501. Grippers 504 are fixedly provided on the circumferential sides of the two rotating shafts 503. The two grippers 504 are arc-shaped and symmetrically arranged. Through the rotating shafts 503, the two grippers 504 can open and close to clamp the pipe pile or release the pipe pile.

[0046] In this embodiment, a fifth fixed base 505 is fixedly provided on the outer side of the gripper 504. A third hydraulic rod 506 is provided between the fourth fixed base 502 and the fifth fixed base 505. The two ends of the third hydraulic rod 506 are respectively hinged to the fourth fixed base 502 and the fifth fixed base 505. The fourth fixed base 502 and the fifth fixed base 505 are connected by the third hydraulic rod 506, and the movement of the gripper 504 can be mechanically controlled.

[0047] In this embodiment, a dovetail groove 507 is provided on the inner side of the gripper 504, and ball bearings 508 are rotatably provided on the inner walls of both sides of the dovetail groove 507. A dovetail column 509 is slidably provided in the dovetail groove 507, and a protective plate 510 is fixedly provided at the front end of the dovetail column 509. A fixing component 6 is provided between the dovetail groove 507 and the dovetail column 509. Through the dovetail groove 507 and the dovetail column 509, the protective plate 510 and the gripper 504 are connected together and can slide up and down. During the support process, the gripper 504 clamps the pile body through the protective plate 510. The sliding design between the protective plate 510 and the gripper 504 will not hinder the pile body from being pressed into the ground.

[0048] In this embodiment, the fixing component 6 includes a sloping groove 602 formed on the inner contact surface of the dovetail post 509 and the dovetail groove 507. A tenon 603 is embedded in the sloping groove 602. A fixing groove 601 is provided on the inner side of the dovetail groove 507. A push rod 604 is provided behind the tenon 603. The push rod 604 passes through the clamp 504 and is fixedly connected to the tenon 603. The tenon 603 is embedded between the fixing groove 601 and the sloping groove 602. The top of the tenon 603 is flat, the lower end of the tenon 603 near the rear end is flat, and the front end is sloping. The top and bottom of the fixing groove 601 are flat, the top of the sloping groove 602 is flat, and the bottom is a sloping surface parallel to the bottom sloping surface of the tenon 603. The latch 603 can hold the protective plate 510 to prevent it from sliding down. When the protective plate 510 moves upward, the inclined surface of the groove 602 and the latch 603 causes the latch 603 to move into the fixed groove 601, allowing the protective plate 510 to slide downward. During the reset, the sliding of the protective plate 510 aligns the fixed groove 601 and the inclined surface groove 602. Pressing the push rod 604 causes the latch 603 to re-lock the protective plate 510. After the mechanical claw assembly 5 picks up the pipe pile, the support assembly 3 and the rotating disk 402 are adjusted to the correct angle, and the pipe pile is placed on the ground. After the pipe pile lands, the claw 504 continues to move downward, thereby moving the latch 603 to release the protective plate 510 and start the pile driving operation.

[0049] In this embodiment, the counterweight box 2 is fixedly connected to the base plate 1. An opening is provided on one side of the counterweight box 2, and a movable baffle 201 is slidably inserted into the outer wall of the left side of the opening. By setting the movable baffle 201, it is possible to put or take out heavy objects in the counterweight box 2 after pulling out the movable baffle 201, so as to avoid the difficulty in taking out when using sand or soil as heavy objects, and to adjust the balance of the support frame.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
