Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically an engineering construction isolation device. Background Technology

[0002] In the field of engineering construction, especially in scenarios such as road maintenance, municipal emergency repairs, and temporary building construction, the need for temporary isolation of construction areas is frequent, and construction sites often change as projects progress. Therefore, construction isolation devices not only need to meet basic isolation functions but also need to have the characteristics of flexible movement and rapid deployment. Currently, most construction isolation devices on the market are fixed frame structures. Although some can be assembled into multiple units by bolting, the overall structure is cumbersome to disassemble, and the disassembled parts are numerous and bulky, making it inconvenient for manual handling or vehicle transportation. There are also a few foldable isolation devices, but their folding structure design is simple, and after folding, they still occupy a lot of space and are inconvenient to carry, making it difficult to adapt to the operational needs of frequently changing construction sites, causing inconvenience in the early deployment and later storage of construction.

[0003] However, the disassembly and assembly of most existing devices rely on a large number of loose connecting parts such as bolts and clips. They need to be tightened one by one during installation and disassembled one by one during disassembly, which consumes a lot of manpower and time. In addition, the connecting parts are easy to be lost, affecting subsequent reuse. It is difficult to meet the actual needs of construction personnel for isolation devices to be "quickly disassembled and portable". Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an engineering construction isolation device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An engineering construction isolation device includes an I-shaped frame, with isolation barrier units hinged to both sides of the I-shaped frame. Connecting components are detachably connected to the ends of the two isolation barrier units that are far apart from each other. An installation cavity is formed inside the upper horizontal plate of the I-shaped frame. A rotating shaft is rotatably connected to the inner wall of the installation cavity, and a gear is fixedly connected to the rotating shaft. Two racks are also provided inside the installation cavity, located on the upper and lower sides of the gear. One half of each rack has a toothed section, and the other half has a toothless section. The toothed sections of both racks mesh with the gear. A fixing block is fixedly connected to the top of each isolation barrier unit near the I-shaped frame. A slot adapted to the toothless section of the rack is formed on the side of the fixing block near the I-shaped frame. Guide sliders are fixedly connected to both the front and rear sides of the rack. A guide groove adapted to the guide slider is formed on the inner wall of the installation cavity.

[0006] Preferably, a steering limiting plate is fixedly connected to the front side of the I-beam frame, and mounting holes are provided at the four corners of the steering limiting plate.

[0007] Preferably, a diagonal brace is fixedly connected to the rear side of the I-beam frame, and a first positioning hole is provided at the bottom of the diagonal brace.

[0008] Preferably, the top of the guardrail unit is provided with anti-tipping rollers.

[0009] Preferably, the rear end of the rotating shaft extends to the rear side of the I-beam frame and is fixedly connected to a knob, and the outer ring of the knob is fixedly connected to a plurality of anti-slip protrusions distributed in a ring array.

[0010] Preferably, the connecting assembly includes a base, a rectangular column fixedly connected to the top center of the base, a top sleeve movably fitted on the top of the rectangular column, a fixing screw threadedly connecting the top sleeve and the rectangular column, and connecting rods symmetrically distributed on the left and right sides of the rectangular column fixedly connected to the top of the base. The length of the connecting rods is the same as the length of the rectangular column. The bottom of the top sleeve has two slots that fit the tops of the two connecting rods. The end of the isolation barrier unit away from the I-beam has a through hole in the vertical direction that fits the connecting rod.

[0011] Preferably, mounting plates are fixedly connected to both the front and rear sides of the base, and the mounting plates are provided with second positioning holes.

[0012] Compared with the prior art, the present invention provides an engineering construction isolation device, which has the following beneficial effects: 1. This utility model effectively solves the problem of cumbersome disassembly and assembly of existing isolation devices. The isolation barrier unit and the I-beam frame are connected by hinges. Through the meshing transmission of gears and racks in the mounting cavity of the I-beam frame and the matching structure of the toothless section of the rack and the slot of the fixing block, the folding and fixing of the isolation barrier unit can be achieved without a large number of scattered connecting parts. At the same time, the connecting components can quickly connect with the connecting uprights through the through holes of the isolation barrier unit, and with the locking of the top sleeve slot and the fixing screws, the splicing and disassembly steps of multiple devices are greatly simplified, reducing manpower and time costs, avoiding the risk of losing connecting parts, and meeting the needs of rapid disassembly and assembly.

[0013] 2. The isolation barrier unit of this utility model can be rotated and folded around the hinge point of the I-beam frame. After folding, the overall volume can be greatly reduced, making it easy to handle manually or transport by vehicle. At the same time, the base, rectangular column, top sleeve and other components of the connecting components are compact in structure. There are no bulky components after disassembly, and each component can be stored in a centralized manner. This effectively solves the problem of large volume and difficulty in carrying traditional fixed frame structure devices after disassembly. It is especially suitable for scenarios such as road maintenance and municipal emergency repairs that require frequent changes of construction sites, improving the convenience of carrying and moving.

Detailed Implementation

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Example 1 Please refer to Figures 1 to 6 As shown, an engineering construction isolation device includes an I-beam frame 1. Isolation barrier units 2 are hinged to both the left and right sides of the I-beam frame 1. Connecting components 3 are detachably connected to the ends of the two isolation barrier units 2 that are far apart from each other. An installation cavity 4 is opened inside the upper horizontal plate of the I-beam frame 1. A rotating shaft 5 is rotatably connected to the inner wall of the installation cavity 4. A gear 6 is fixedly connected to the rotating shaft 5. Two racks 7 are also provided in the installation cavity 4, located on the upper and lower sides of the gear 6. Half of the racks 7 is toothed and the other half is toothless. The toothed sections of the two racks 7 mesh with the gear 6. A fixing block 8 is fixedly connected to the top of the isolation barrier unit 2 near the I-beam frame 1. A slot 9 that matches the toothless section of the rack 7 is opened on the side of the fixing block 8 near the I-beam frame 1. Guide sliders 10 are fixedly connected to both the front and rear sides of the rack 7. A guide groove 11 that matches the guide slider 10 is opened on the inner wall of the installation cavity 4.

[0018] Those skilled in the art will understand that the rotating shaft 5 can drive the gear 6 fixed thereon to rotate synchronously; the two racks 7 on the upper and lower sides of the gear 6 mesh with the gear 6 through toothed sections. When the gear 6 rotates, the two racks 7 move in opposite directions, and the guide sliders 10 on the front and rear sides of the racks 7 slide in the guide grooves 11 on the inner wall of the mounting cavity 4 to ensure that the movement direction of the racks 7 is stable; when the two isolation barrier units 2 rotate to a horizontal line, the toothless section of the rack 7 can be aligned with the slot 9 and inserted to realize the rapid unfolding and fixing of the two isolation barrier units 2.

[0019] Example 2 Furthermore, a steering limiting plate 12 is fixedly connected to the front side of the I-beam frame 1, and mounting holes 13 are provided at the four corners of the steering limiting plate 12.

[0020] Those skilled in the art will understand that when the two folded guardrail units 2 are unfolded, the turning limit plate 12 can limit the turning range of the two guardrail units 2, so that the toothless section of the rack 7 can quickly align with the slot 9, preventing the guardrail units 2 from exceeding the preset use angle due to excessive rotation. At the same time, the mounting hole 13 facilitates the installation of warning signs and other components.

[0021] Example 3 Furthermore, a diagonal brace 14 is fixedly connected to the rear side of the I-beam frame 1, and a first positioning hole 15 is provided at the bottom of the diagonal brace 14.

[0022] Those skilled in the art will understand that the first positioning hole 15 can be fixed to the ground by anchor bolts or the like; the diagonal brace reinforcement 14 is inclined to connect the I-beam frame 1 to the ground, forming a triangular support structure. By utilizing the stability principle of triangles, the vertical and horizontal external forces on the I-beam frame 1 are dispersed, reducing the risk of the I-beam frame 1 tipping over.

[0023] Example 4 Furthermore, the top of the guardrail unit 2 is equipped with anti-overturning rollers 16.

[0024] Those skilled in the art will understand that the anti-climbing roller 16 can rotate freely; when a non-construction worker attempts to climb over the guardrail unit 2, the contact between the body and the anti-climbing roller 16 will cause the roller to rotate, making it difficult for the worker to obtain a stable support point, thereby preventing the climbing behavior.

[0025] Example 5 Furthermore, the rear end of the rotating shaft 5 extends to the rear side of the I-beam frame 1 and is fixedly connected to a knob 17. The outer ring of the knob 17 is fixedly connected to several anti-slip protrusions 18 distributed in a ring array.

[0026] Those skilled in the art will understand that the anti-slip protrusions 18 on the outer ring of the knob 17 can increase the friction between the hand and the knob 17; when the operator rotates the knob 17, it can drive the rotating shaft 5 and the gear 6 to rotate synchronously, thereby controlling the movement of the rack 7 and realizing the angle adjustment and fixation of the isolation barrier unit 2.

[0027] Example 6 Furthermore, the connecting component 3 includes a base 301, a rectangular column 302 fixedly connected to the top center of the base 301, a top sleeve 303 movably fitted on the top of the rectangular column 302, and a fixing screw 304 threadedly connected between the top sleeve 303 and the rectangular column 302. The top of the base 301 is also fixedly connected with connecting rods 305 symmetrically distributed on the left and right sides of the rectangular column 302. The length of the connecting rods 305 is the same as the length of the rectangular column 302. The bottom of the top sleeve 303 has two slots 306 that are adapted to the tops of the two connecting rods 305. The end of the isolation barrier unit 2 away from the I-beam 1 has a through hole 307 in the vertical direction that is adapted to the connecting rod 305.

[0028] Those skilled in the art will understand that during assembly, the through hole 307 of the isolation barrier unit 2 is inserted into the connecting rod 305, and then the top sleeve 303 is placed on the rectangular post 302, so that the slot 306 at the bottom of the top sleeve 303 engages with the top of the connecting rod 305. Finally, the fixing screw 304 is tightened to complete the assembly of the two sets of devices. The structural design of the connecting component 3 enables rapid assembly of the isolation device, significantly saving manpower and time compared to the existing cumbersome assembly methods. The engagement of the top sleeve 303 and the connecting rod 305, combined with the locking of the fixing screw 304, ensures the firmness of the assembly, solving the problem of easy loosening and separation after assembly of existing devices, and forming a continuous and stable isolation barrier.

[0029] Example 7 Furthermore, mounting plates 19 are fixedly connected to both the front and rear sides of the base 301, and the mounting plates 19 are provided with second positioning holes 20.

[0030] Those skilled in the art will understand that the second positioning hole 20 can be fixed to the ground by means of expansion bolts or other connecting parts; during installation, the expansion bolts are passed through the second positioning hole 20 and driven into the ground, so that the base 301 forms a firm connection with the ground, thereby enhancing the stability of the connecting component 3 and the entire isolation device.

[0031] The working principle and usage process of this device are as follows: First, rotate and unfold the two folded isolation barrier units 2 until they are in a straight line. Then, the operator rotates the knob 17 in the forward direction, driving the rotating shaft 5 and gear 6 to rotate, causing the two racks 7 to move in opposite directions, so that the toothless section of the rack 7 is inserted into the slot 9, thereby fixing the two isolation barrier units 2. Then, through the first positioning hole 15, use anchor bolts to fix the I-beam frame 1 to the ground in the construction area. At the same time, use the second positioning hole 20 to fix the base 301 to the preset position on the ground with expansion bolts. If multiple sets of devices need to be spliced, put the through hole 307 at one end of the isolation barrier unit 2 of another set of devices onto the connecting pole 305 of the fixed connecting component 3, and then put the top sleeve 303 on the top of the rectangular column 302, so that the slot 306 at the bottom of the top sleeve 303 engages with the top of the connecting pole 305. Finally, use the fixing screw 304 to thread the top sleeve 303 and the rectangular column 302 to complete the splicing.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
