Description
Technical Field
[0001] The utility model relates to the technical field of pipe pile movement, in particular to a prestressed pipe pile movement control device. Background Art
[0002] Prestressed pipe piles, also known as prestressed concrete pipe piles, can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles. Pre-tensioned prestressed pipe piles are hollow cylindrical slender concrete prefabricated components made using pre-tensioned prestressing technology and centrifugal forming method.
[0003] In the prior art, the Chinese utility model with publication number CN219219014U discloses a prefabricated stress pipe pile movement control device, comprising a support steel pipe, support plates fixedly connected to both sides of the surface of the support steel pipe, the front and back sides of the support plate are hinged to a hydraulic cylinder via a shaft and a sleeve, the front and rear sides of the bottom of the support plate are provided with an arc-shaped splint, the top of the arc-shaped splint is hinged to the bottom of the support plate via a shaft and a sleeve, and the output end of the hydraulic cylinder is hinged to the top of the arc-shaped splint via a shaft and a sleeve. In this utility model, the hydraulic cylinder drives the arc-shaped splint to rotate and sleeve on the surface of the prestressed pipe pile, and then an external forklift drives the arc-shaped splint and the prestressed pipe pile to move through the support steel pipe and the support plate, which facilitates unloading and achieves the advantages of convenient and fast loading and unloading. It does not require the use of a wire rope sleeved on the surface of the prestressed pipe pile for control, thereby improving the user's loading and unloading efficiency of the prestressed pipe pile.
[0004] Although the mobile control device in the above technical solution is convenient for rapid clamping and loading and unloading, this technical solution can only clamp the middle and upper parts of the pipe pile when clamping the pipe pile through the arc plate, and is not convenient for clamping pipe piles of different diameters. When the diameter of the pipe pile is large, the clamping range of the clamping plate is limited, which leads to a reduction in the clamping effect of the pipe pile, which may cause the pipe pile to fall during the movement, increasing the safety risk. The stability of the clamping movement of the pipe pile needs to be further improved. Therefore, we need to propose a prestressed pipe pile movement control device. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-3 The utility model provides a technical solution: a prestressed pipe pile movement control device, comprising a connecting steel pipe 1, both ends of the outer side of the connecting steel pipe 1 are fixedly connected to a fixed frame 4, an adjusting mechanism 5 is provided in the fixed frame 4, and two sets of clamping mechanisms 7 are provided at the lower end of the adjusting mechanism 5, and a hydraulic cylinder 6 is provided between the adjusting mechanism 5 and the clamping mechanism 7;
[0023] The adjustment mechanism 5 includes a bidirectional screw 51 rotatably connected to the inner cavity of the fixed frame 4. Both ends of the bidirectional screw 51 are threadedly connected to displacement clamps 54. The opposite sides of the two sets of displacement clamps 54 are fixedly connected to the first mounting hinge 56 for rotatably mounting the hydraulic cylinder 6.
[0024] The clamping mechanism 7 includes two groups of arc-shaped clamping plates 71, and the outer sides of the two groups of arc-shaped clamping plates 71 are fixedly connected with a second mounting hinge 74 for rotating connection of the telescopic end of the hydraulic cylinder 6. The lower surfaces of the two groups of displacement clamping plates 54 are provided with mounting grooves 55 for rotating installation of the arc-shaped clamping plates 71.
[0025] A second anti-slip pad 75 is fixedly connected to the inner side of the arc-shaped clamping plate 71, and multiple groups of reinforcing ribs 73 are provided on the outer side of the arc-shaped clamping plate 71. The multiple groups of reinforcing ribs 73 are arranged at equal intervals. The second anti-slip pad 75 increases the friction with the outer surface of the pipe pile, thereby improving the stability of the pipe pile during clamping and movement.
[0026] The lower ends of the displacement clamp 54 and the two adjacent sides of the first mounting hinge seat 56 are both connected with fixed pins 72 that are rotatably connected to the arc clamp 71. The arc clamp 71 can be flipped 0-60 degrees with the fixed pin 72 as the axis. The telescopic end of the hydraulic cylinder 6 is extended, and the arc clamp 71 is flipped with the fixed pin 72 as the axis, so that the second anti-slip clamping pad 75 contacts the pipe pile, thereby improving the stability of the clamping.
[0027] The lower ends of the opposite sides of the displacement splints 54 are fixedly connected with first anti-slip pads 57, and the opposite sides of the two groups of first anti-slip pads 57 are provided with inner arc grooves. The two groups of first anti-slip pads 57 are respectively arranged above the two groups of second anti-slip pads 75. The first anti-slip pads 57 facilitate pre-clamping of the pipe piles, and at the same time avoid damage to the displacement splints 54 caused by rigid clamping, thereby improving the overall service life and adaptability range of the device.
[0028] Two groups of horizontal guide rods 52 are fixedly connected to the inner cavity of the fixed frame 4. Through holes for the horizontal guide rods 52 to pass through are opened on the opposite sides of the two groups of displacement splints 54. The bidirectional screw 51 and the two groups of horizontal guide rods 52 are arranged in the same plane. One end of the bidirectional screw 51 passes through the fixed frame 4 and is driven by the forward and reverse motor 53. The horizontal guide rod 52 improves the stability of the two groups of displacement splints 54 during relative movement.
[0029] The cross section of the displacement clamping plate 54 is set in a right-angled trapezoid. Two groups of connecting plates 41 fixedly connected to the connecting steel pipe 1 are symmetrically welded on the upper surface of the fixed frame 4. The connecting plates 41 improve the installation stability of the fixed frame 4.
[0030] The outer side of the connecting steel pipe 1 is fixedly connected with a reinforcing beam 3 located between two sets of connecting plates 41. The cross-section of the reinforcing beam 3 is arched. The outer side of the connecting steel pipe 1 is fixedly connected with two sets of connecting rings 2. The reinforcing beam 3 improves the overall bearing capacity of the connecting steel pipe 1, thereby improving the overall service life of the device.
[0031] When in use, the connecting ring 2 is hung on an external forklift, and then the device is moved above the pipe pile. First, the bidirectional screw 51 is driven to rotate by the forward and reverse motor 53 to make the two sets of displacement clamps 54 relatively close to each other, so that the first anti-slip clamping pad 57 contacts the outer surface of the pipe pile. The second mounting hinge seat 74 is driven to move by the extension end of the hydraulic cylinder 6. After the arc-shaped clamping plate 71 is flipped with the fixed pin 72 as the axis, the second anti-slip clamping pad 75 contacts the lower end of the outer side of the pipe pile, thereby completing the clamping and fixing of the pipe pile, improving the stability of the clamped pipe pile, and moving the mobile device to the designated ground by the external forklift, thereby realizing the movement of the pipe pile and improving the moving efficiency.
[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
