Description

Technical Field

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

[0002] When constructing a highway, for the safety of construction workers, it is necessary to set up corresponding isolation devices in the construction area to separate the construction area from the driving area. On the one hand, this prevents the normal driving of passing vehicles from being affected during construction, and on the other hand, it protects the personal safety of construction workers in the construction area.

[0003] However, the railings above the existing isolation barriers cannot be disassembled separately. In the event of a collision, the isolation barriers need to be replaced as a whole, resulting in a waste of resources. In addition, the existing isolation barrier protection structure is simple and the protection is insufficient, which affects the protection effect. Therefore, in order to correct the above defects, we propose an isolation device for highway construction safety. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figures 1 to 4 The embodiment of the utility model is an isolation device for highway construction safety, which includes a positioning frame 1: a pair of support blocks 2 are fixedly connected to the bottom of the positioning frame 1, and a positioning block 3 is provided above the positioning frame 1, a pair of first bolts 4 pass through the positioning block 3, and a threaded groove matching the first bolt 4 is opened on the top of the positioning frame 1, and a plurality of railings 5 are provided in the positioning frame 1, and the top and bottom ends of the railings 5 are fixedly connected to the limit rod 6, and a plurality of limit grooves 7 matching the limit rod 6 are opened on the bottom of the positioning block 3 and the inner wall of the bottom of the positioning frame 1, and rubber rings 8 are fixedly connected to the rod bodies of the plurality of railings 5, and an interception mechanism is provided on the positioning frame 1.

[0024] The force is evenly distributed, and a pair of support blocks 2 are symmetrically arranged about the central axis of the positioning frame 1.

[0025] To increase the friction force at the bottom of the support block 2, a pair of support blocks 2 are provided with anti-slip grooves at the bottom.

[0026] In order to improve the comprehensiveness of the protection of the device, a plurality of railings 5 are evenly distributed on the positioning frame 1.

[0027] The force is evenly distributed, and the pair of first bolts 4 are symmetrically arranged about the central axis of the positioning block 3 .

[0028] To prevent people from climbing over the isolation fence and improve the protective effect of the isolation fence, the interception mechanism includes a pair of limiting rings 9, which are fixedly connected to the side walls of the positioning frame 1, and a vertical block 10 passes through the limiting ring 9, and an interception block 11 is fixedly connected to the top of a pair of vertical blocks 10. A second bolt 12 is threadedly connected to the side wall of the limiting ring 9, and a number of slots 13 are opened on the side wall of the vertical block 10.

[0029] In order to facilitate the upward and downward movement of the intercepting block 11 , anti-slip grooves are provided on the side walls of the intercepting block 11 .

[0030] Working principle: When the present invention is used, the isolation device is placed at the isolation location, and then the height of the intercepting block 11 is adjusted up and down until the height of the intercepting block 11 is appropriate, and then the second bolt 12 is screwed until the second bolt 12 is inserted into the card slot 13 at the appropriate position, thereby preventing people from turning over the isolation device and improving the isolation effect of the isolation device. When the railing 5 on the isolation device is hit, the rubber ring 8 absorbs the impact force, thereby improving the protective effect of the railing 5. When the impact is too large and causes the railing 5 to be damaged, unscrew the first bolt 4, remove the positioning block 3, and then remove the damaged railing 5, and insert the limiting rod 6 at the bottom of the new railing 5 into the limiting groove 7 on the positioning frame 1, and then place the positioning block 3 above the positioning frame 1, and insert the limiting rod 6 at the top of the railing 5 into the limiting groove 7 at the bottom of the positioning block 3.
