Description

Technical Field

[0001] The utility model relates to the technical field of construction safety, in particular to an isolation device for highway expansion construction. Background Art

[0002] With the improvement of living standards and the continuous development of the economy, there are more and more cars on the road. All regions need more convenient, fast and safe transportation services. In order to meet the growing demand for traffic volume, the original highways need to be expanded.

[0003] Expressways have the advantages of high speed, high efficiency and large transport volume, which can improve transportation efficiency. Expansion projects usually include building new lanes, widening and adding emergency lanes on the basis of the original roads, etc., which can meet the increasing traffic needs.

[0004] During the process of highway expansion construction, in order to prevent vehicles from mistakenly entering the construction area, an isolation device is set at the edge of the construction area. In the actual use of highway expansion construction isolation devices in the existing technology, most of them adopt traditional bolt connection methods, which leads to low overall assembly convenience of the isolation device and inconvenience in use, thereby reducing the installation and disassembly efficiency at the highway expansion construction site. Therefore, the utility model proposes a highway expansion construction isolation device. Utility Model Content

[0005] In order to overcome the problem that the existing technology mostly uses traditional bolt connection methods, resulting in low overall assembly convenience of the isolation device, inconvenience in use, and reduced installation and disassembly efficiency at the highway expansion construction site, the utility model provides a highway expansion construction isolation device. The technical solution is as follows:

[0006] A highway expansion construction isolation device includes multiple guardrail bodies and multiple columns, and two adjacent guardrail bodies are connected by the columns; side sliders are fixed to both end surfaces of the guardrail bodies, and two top sliding grooves for the side sliders to slide into are symmetrically provided at both ends of the top surface of the columns; two bottom insertion rods are symmetrically fixed to both ends of the bottom surface of the guardrail body, and bottom support blocks corresponding to the bottom insertion rods are fixed to the lower ends of the two side surfaces of the columns, and the bottom insertion rods pass through the bottom support blocks from top to bottom, and a connecting mechanism is also provided between the guardrail body and the columns.

[0007] Furthermore, the connecting mechanism includes a rectangular card plate movably mounted on the front surface of the column, rectangular card holes are provided at both ends of the rectangular card plate, and rectangular strips corresponding to the rectangular card holes are fixed to the front surface of the guardrail body, and the two ends of the rectangular card plate are respectively sleeved on the two rectangular strips; the connecting mechanism also includes a rear slide groove provided on the rear surface of the column, a rear slide rod is fixed on the rear surface of the rectangular card plate, and the rear end of the rear slide rod passes through the rear surface of the column and is rotatably mounted with the rear card plate, and both ends of the rear card plate can be clamped on the rear surface of the column to limit the rear slide rod.

[0008] Furthermore, the connecting mechanism also includes two inner grooves opened inside the column, and a spring and a telescopic bead are arranged inside the inner groove. Both ends of the inner side surface of the rear card plate are provided with limiting grooves corresponding to the telescopic bead. The telescopic bead is movably installed in the inner groove through the spring, and the telescopic bead can pop out into the limiting groove, which is used to limit the rotation of the rear card plate to ensure that the rear card plate does not rotate on its own.

[0009] Furthermore, a through-hole communicating with the rear sliding groove is formed through the front surface of the column, and the through-hole corresponds to the rear sliding rod, so as to facilitate smooth penetration and subsequent sliding of the rear sliding rod.

[0010] Furthermore, one inner end of the spring is fixed to the inner wall of the inner groove, and the other end of the spring is fixedly connected to the telescopic bead, thereby ensuring the installation stability of the spring and the telescopic bead.

[0011] Furthermore, a shaft with a T-shaped cross-section is fixed to one end of the rear slide bar close to the rear card plate, and the rear card plate is rotatably sleeved on the shaft, so that the rear card plate can rotate smoothly on the rear slide bar and is prevented from falling off by being limited by the shaft.

[0012] The positioning protrusion is arranged on the two sides of the rubber seat and is embedded in the mounting groove. The positioning protrusion is arranged on both sides of the rubber seat and is integrated. The positioning protrusion is made of rubber material and elastically deforms when squeezed. The positioning protrusion extends out of the top slide groove and is located at the top of the side slider. When the guardrail body and the column are assembled, the side slider slides from the top of the column into the top slide groove, so that the side slider squeezes and deforms the positioning protrusion until the side slider slides to the bottom end of the top slide groove over the positioning protrusion. At this time, the positioning protrusion will recover under its own elastic action and be at the top of the side slider, which can play a certain auxiliary positioning role for the side slider, prevent the side slider from sliding up, and facilitate the subsequent operator to further connect the guardrail body and the column.

[0013] The beneficial effects of the technical solution provided by the utility model are as follows: the device can quickly assemble the guardrail body and the column through the top slide, side slider, bottom plug rod, bottom support block and other structures, and connect and fix them through the connecting mechanism, which not only improves the installation efficiency of the device but also improves the stability of the device;

[0014] The device also provides preliminary fixation when assembling the guardrail body and the column through the auxiliary positioning structure, which facilitates the operator to further connect the guardrail body and the column. BRIEF DESCRIPTION OF THE DRAWINGS
