Description

Technical Field

[0001] This utility model relates to the field of regulator technology, and in particular to a novel regulator for steel trestle decks used in deep foundation pits. Background Technology

[0002] Steel trestle platforms for deep foundation pits are prefabricated steel plate structures, typically welded from shaped steel sections and reinforced with stiffening ribs to enhance their strength and stability. The main body is encased in side panels, with a surface covered in patterned steel plates for excellent anti-slip properties. The steel trestle platform adjuster is a crucial auxiliary device during the construction and use of deep foundation pit steel trestle platforms. Its core function is to precisely adjust the installation state of the steel trestle platforms, resolving on-site construction errors, adapting to working conditions, and addressing subsequent maintenance issues, thereby ensuring the safe, stable, and efficient use of the steel trestle platform.

[0003] Currently, steel trestle bridges in use often experience warping and unevenness due to the inability of the supporting beams to achieve standard levelness. During vehicle traffic, the trestle bridge panels can tilt, causing them to shift, generate collision noise, and pose safety hazards. Existing technologies using manual leveling with rubber and steel shims are time-consuming and labor-intensive. Furthermore, factors such as vehicle loads and friction, rubber wear, and movement of the steel shims during use cannot effectively address these safety issues, thus preserving the safety risks. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel steel trestle plate adjuster for deep foundation pits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel adjuster for steel trestle platforms used in deep foundation pits includes a seamless steel pipe and bolts. The bolts are located inside the seamless steel pipe, which has three sets of pads. The bolts are rotatably connected to two sets of pads, and one set of pads is integrally connected to the bottom end of the bolt. The pads at the bottom end of the bolts are rotatably connected to the bottom opening of the seamless steel pipe. The two sets of pads rotatably mounted on the bolts are fixedly connected inside the seamless steel pipe and located on top of one set of pads. Nuts are fixedly connected to the top and bottom of both sets of pads, and the bolts are threadedly connected to several of the nuts.

[0006] As a further embodiment of this utility model, a skeleton sealing ring is inserted and installed at the top opening of the seamless steel pipe, the bottom of the skeleton sealing ring abuts against the top of the pad at the top of the seamless steel pipe, and the bolt is located in the middle of the skeleton sealing ring.

[0007] Compared with the prior art, the present invention has the following beneficial effects: The adjuster is installed at the bottom of the steel trestle via a support frame. When the adjuster is turned around, the original bottom pad of the seamless steel pipe rests against the bottom of the steel trestle. Then, the skeleton sealing ring installed at the top of the seamless steel pipe is opened. A socket wrench is applied to the top of the bolt, and the bolt is rotated manually or by motor drive. The bolt rotates in the middle of the two sets of pads. The bolt surface has a double-ended trapezoidal thread, and the trapezoidal threads at both ends of the helix are connected to the threads of the two sets of nuts respectively. As the bolt rotates, it moves down and pushes out the pad at the bottom of the seamless steel pipe, so that the pad lifts the steel trestle and adjusts the height of the steel trestle. This design is time-saving, labor-saving, and convenient for workers to operate. Attached Figure Description

Three sets of pads 4 are provided inside the seamless steel pipe 1. Bolts 2 are rotatably connected to two sets of pads 4. One set of pads 4 is integrally connected to the bottom end of bolt 2. The pads 4 at the bottom end of bolt 2 are rotatably connected to the bottom opening of seamless steel pipe 1. The two sets of pads 4 rotatably installed on bolt 2 are fixedly connected inside seamless steel pipe 1 and located on top of one set of pads 4. Nuts 3 are fixedly connected to the top and bottom of both sets of pads 4. Bolt 2 is threadedly connected to several nuts 3.

[0014] In use, the adjuster is installed at the bottom of the steel trestle via a support frame that is part of the existing steel trestle support installation device. The adjuster is turned around, and the original bottom pad 4 of the seamless steel pipe 1 rests against the bottom of the steel trestle. Then, the skeleton sealing ring 5 installed at the top of the seamless steel pipe 1 is opened. A socket wrench is applied to the top of the bolt 2, and the bolt 2 is rotated manually or by motor drive. The bolt 2 rotates in the middle of the two sets of pads 4. The surface of the bolt 2 has a double-headed trapezoidal thread, and the trapezoidal threads at both ends of the helix are threadedly connected to the two sets of nuts 3 respectively. As the bolt 2 rotates, it moves down and pushes out the pad 4 at the bottom of the seamless steel pipe 1, so that the pad 4 lifts the steel trestle and adjusts the height of the steel trestle.

[0017] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The adjuster is installed at the bottom of the steel trestle through the support frame, which is a support installation device of the existing steel trestle. When the adjuster is turned around, the original bottom end pad 4 of the seamless steel pipe 1 rests against the bottom of the steel trestle. Then, the skeleton sealing ring 5 installed at the original top of the seamless steel pipe 1 is opened. A socket wrench is used to act on the top of the bolt 2, and the bolt 2 is rotated manually or by motor drive. The bolt 2 rotates in the middle of the two sets of pads 4. The surface of the bolt 2 is provided with a double-headed trapezoidal thread. The trapezoidal threads at both ends of the spiral are respectively threaded to the two sets of nuts 3. When the bolt 2 rotates, it moves down and pushes out the pad 4 at the bottom of the seamless steel pipe 1, so that the pad 4 lifts the steel trestle and raises it, thereby adjusting the height of the steel trestle. This design is more time-saving and labor-saving, and convenient for workers to operate.
