Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile planting construction technology, specifically a limiting device for prestressed pipe pile planting construction. Background Technology
[0002] Prestressed concrete pipe piles are precast concrete piles with a hollow circular cross-section, manufactured in a factory using pre-tensioning prestressing technology and centrifugal molding. With their high strength, good impact resistance, fast construction speed, and high bearing capacity, they have become one of the most widely used pile foundation types in industrial and civil buildings, bridges, ports, and other engineering projects. In construction methods such as pile driving, limiting devices are needed to fix and guide the prestressed concrete pipe piles to ensure that they do not undergo horizontal displacement or tilting during the driving process into the soil.
[0003] The existing patent publication number CN222782060U discloses an adjustable pile body limiting device for prestressed pipe pile installation, which includes a horizontally set roadbed box, a limiting bracket set on the roadbed box, and an adjustable limiting clamp fixedly connected to the limiting bracket. The limiting bracket has a through-hole in the center, through which the precast pipe pile is driven into the pile hole. The adjustable limiting clamp is installed on the limiting bracket. The adjustable limiting clamp includes two semi-circular steel plates that are spliced together on both sides. The semi-circular steel plates surround the side wall of the precast pipe pile. An adjustable thickness square steel is set in the gap between the two sides of the semi-circular steel plates. The limiting bracket has a movable bolt slot, through which the semi-circular steel plates are bolted to the limiting bracket.
[0004] The aforementioned limiting device can be used for limiting the installation of prestressed concrete pipe piles. However, during the limiting process, the adjustable limiting clamp consists of two sets of semi-circular steel plates. After the device is placed at the target position, it is inconvenient to adjust the diameter for centering, which easily leads to deviation from the pile center and affects the limiting. To address these issues, a limiting device for prestressed concrete pipe pile installation is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a limiting device for prestressed pipe pile planting construction, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A limiting device for prestressed pipe pile installation, comprising:
[0008] The support frame includes a support plate, casters mounted on the bottom of the support plate, and a guide groove provided on the top of the support plate;
[0009] An adjusting frame, which includes an adjusting ring;
[0010] Four sets of limiting mechanisms, including a limiting plate and a lever rotatably connected to the outer side of the top of the limiting plate, the end of the lever away from the limiting plate being rotatably connected to the bottom of the adjusting ring, the bottom of the limiting plate being connected to a guide that can slide on the support plate; and an adjusting mechanism installed between the support plate and the adjusting ring for adjusting the height of the adjusting ring.
[0011] In one alternative: the support plate has at least two sets of perforations, and buried rods are inserted through the perforations; the top of the support plate is connected to two sets of handrails.
[0012] In one alternative embodiment: the guide includes a movable strip connected to the bottom of the limiting plate, the bottom of the movable strip is rotatably connected to a roller, and the top of the support plate is provided with a guide groove for sliding of the movable strip and a groove for rolling of the roller, the groove being disposed at the bottom of the guide groove.
[0013] In one alternative: two sets of handles are connected to the adjusting ring.
[0014] In one alternative embodiment: the adjusting mechanism includes a sleeve connected to the top of the support plate and an adjusting rod connected to the bottom of the adjusting ring. The bottom end of the adjusting rod is slidably disposed inside the sleeve. A limiting bolt is threadedly connected to one side of the sleeve. A plurality of limiting holes corresponding to the limiting bolts are provided on one side of the adjusting rod. The limiting holes are disposed on one side of the handle.
[0015] In one alternative embodiment, the adjusting mechanism further includes a fixed sleeve connected to the top of the support plate and a slide rod connected to the bottom of the adjusting ring, the bottom end of the slide rod being slidably disposed within the fixed sleeve.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] In this invention, the limiting plates in the four sets of limiting mechanisms can be adjusted synchronously. By adjusting the height of the ring, the four sets of limiting plates are moved horizontally synchronously via the lever, so that the limiting plates move closer to or further away from the center of the pipe pile from all sides at the same time. This synchronous adjustment mechanism ensures that the pipe pile is always located in the center of the device, effectively preventing the problem of deviating from the center of the pile, and improving the limiting accuracy and the verticality of the pipe pile.
[0018] In this invention, the adjusting ring is height-fixed by a handle and a limiting bolt, the adjusting rod slides within the sleeve, and the limiting hole and the limiting bolt provide precise position locking. The entire adjustment process does not require individual adjustment of each limiting plate, shortening the adjustment time and adapting to on-site construction needs.
[0019] In this invention, the movable wheels at the bottom of the support frame allow the device to be easily pushed to the planting point. Once there, it is driven into the ground by the buried pole, achieving rapid and stable fixation. This prevents the device from shifting during construction and improves construction efficiency.
