Description

A micro-adjustment device for hanging basket straps Technical Field

[0001] This utility model belongs to the field of building construction equipment design technology, and relates to the design of auxiliary equipment for bridges in civil engineering, specifically a hanging basket sling micro-adjustment device. Background Technology

[0002] In cantilever bridge construction, the formwork, as the main construction equipment, plays a crucial role in construction quality and safety through its stability and precise positioning. The formwork slings are important components connecting the formwork and the main beam. During construction, the suspension length and stress of the formwork slings need to be precisely adjusted according to the pouring progress of the main beam, changes in concrete weight, and various load conditions during construction.

[0003] Currently, the traditional method of adjusting the slings of a hanging basket mainly involves manual adjustment using tools such as jacks. This method has several drawbacks: firstly, the precision of manual adjustment is difficult to guarantee, easily leading to adjustment errors, uneven stress on the hanging basket, and affecting construction quality and structural safety; secondly, the manual adjustment process is cumbersome, time-consuming, and inefficient, making it difficult to meet the requirements of modern bridge construction's rapid pace. Furthermore, traditional adjustment methods lack flexibility and real-time capability when facing complex and changing construction conditions, failing to provide timely and effective precise adjustment of the slings. Summary of the Invention

[0004] The purpose of this invention is to provide a micro-adjustment device for the hanging basket slings, to solve the problems of low adjustment accuracy, poor efficiency, and insufficient flexibility in the existing technology, and to achieve precise, efficient, and real-time adjustment of the hanging basket slings, thereby ensuring the quality and safety of bridge cantilever construction.

[0005] This utility model is achieved through the following technical solution:

[0006] A micro-adjustment device for a hanging basket sling includes a cantilever beam for suspending a construction hanging basket and a steel sling, with positioning holes evenly spaced along the axial direction at the upper end of the sling; characterized in that: the adjustment device is set on the cantilever beam and consists of an upper base, a lower base, a first bolt, a second bolt, a buffer device, and a gauge.

[0007] The upper base and the lower base are two parallel planar support plates;

[0008] The caliper is a hollow steel cylinder that allows steel slings to pass through. The cylinder has multiple positioning holes that pierce through the cylinder wall at the same intervals as the slings. The upper end of the caliper is fixedly connected to the upper base, and the lower end slides into a hole of matching size set in the middle of the lower base.

[0009] Two sets of buffer devices are respectively installed on both sides of the caliper and between the upper base and the lower base; each set of buffer devices includes a spring that is fixed to the upper base and a spring limiting and fixing seat that is fixed to the lower base.

[0010] The No. 1 and No. 2 bolts have diameters that match the positioning holes of the steel sling and the gauge. The No. 1 bolt is used to pass laterally through the positioning hole of the steel sling and is positioned above the upper base for limiting support and fixation. The No. 2 bolt is used to pass laterally through the positioning holes of the gauge and the steel sling and is positioned above the lower base for limiting support and fixation.

[0011] Furthermore, the cantilever beams are two parallel beams, and the slings pass through the space between the two cantilever beams. The lower base has L-shaped fixing slots on both sides of the flat support plate, and the fixing slots are embedded and fixed to the edge of the cantilever beams.

[0012] Furthermore, the spring limiting and fixing seat is a sleeve structure with an open top, and the bottom is fixed to the surface of the lower base and fixed by reinforcing ribs; the top of the spring of the buffer device is connected and fixed to the bottom surface of the upper base, and the lower part of the spring is embedded in the spring limiting and fixing seat of the sleeve structure.

[0013] Furthermore, the first and second locking bolts are radially provided with pins to prevent the locking bolts from freely sliding out of the positioning holes.

[0014] The method of using this utility model adjustment device is as follows: During construction, construction personnel use measuring tools such as levels and total stations to obtain data on the deformation of the main beam and the load borne by the hanging basket. Based on this data, the construction personnel can loosen the No. 1 bolt from the current positioning hole, set the suspension position of the sling and the upper base, and re-insert the No. 1 bolt to fix it; adjust the tension of the sling by adjusting the buffer device, and then simultaneously insert the No. 2 bolt into the positioning hole above the lower base along with the gauge, thus completing the adjustment of the length and force of the hanging basket sling.

[0015] This utility model has a buffer device set between the upper and lower bases, and the force on the sling can be adjusted by adjusting the buffer spring.

[0016] The support arms are at least two parallel extension beams that are connected and fixed to the truss. The length of the support arms is greater than the length of the gap in the closure section. Both ends of each support arm are fixed to the bridge structure that has been cast and solidified at both ends of the closure section of the side span of the bridge.

[0017] This utility model's snap-on adjustment device simplifies the adjustment process of steel slings. Construction workers only need to loosen, move, and adjust the buckles. Compared to traditional, complex manual adjustment methods, this reduces the number of steps and improves work efficiency. This adjustment device is not limited by external factors such as power supply and can work stably in various complex construction environments, adapting to different construction conditions.
