Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and in particular to a safety enclosure for highway construction which is easy to disassemble. Background Art

[0002] During highway construction, safety fences are one of the essential safety facilities. They can not only effectively isolate the construction site, prevent irrelevant personnel from entering, and ensure the safety of construction workers and passers-by, but also serve as a warning, reminding vehicles to slow down. Traditional highway construction safety fences mostly adopt fixed or semi-fixed structures, which are cumbersome, time-consuming and labor-intensive to install and remove, especially when the construction site is frequently changed. This undoubtedly increases the construction cost and time cost.

[0003] Although traditional safety fences can meet basic isolation needs to a certain extent, they have exposed many shortcomings in actual applications. First, the installation and disassembly process of traditional fences is usually cumbersome and requires a lot of manpower and time, which not only reduces construction efficiency, but also increases project costs to a certain extent. Secondly, since most traditional fences adopt a fixed design with poor mobility, once the construction site changes, rearranging the fence becomes an arduous task, which seriously affects the construction progress. Therefore, it is necessary to design a safety fence for highway construction that is easy to disassemble in view of the shortcomings of the existing technology. Utility Model Content

[0020] Embodiment: A safety enclosure for highway construction that is easy to disassemble, such as Figure 1-Figure 4As shown, it includes a baffle 1, which is the main body of the enclosure, and a through hole is opened at the central position of the bottom of the baffle 1; it also includes: a motor 2, which is installed on one side of the upper part of the baffle 1; a warning sign 3, which is hinged to the upper part of the baffle 1 through a hinge shaft 31, and the output shaft of the motor 2 is connected to the hinge shaft 31 of the warning sign 3, and the hinge shaft 31 is driven by the motor 2 to enable the warning sign 3 to be opened or stored on the baffle 1; two guide rods 6, which are symmetrically fixed to the bottom of the baffle 1; a sliding frame 5, which is slidably set at the bottom through the guide rod 6, and the sliding frame 5 is a hollow frame. The sliding frame 5 is used to load objects (sandbags and stones, etc.) of the enclosure counterweight so that the entire baffle 1 can be stably placed at the site of highway construction; a spring 7, which is set between the sliding frame 5 and the baffle 1 to hold multiple baffles After the guards 1 are placed side by side, the warning sign 3 is automatically driven by the motor 2 to flip and open from the baffle 1, and a counterweight object is placed in the sliding frame 5 to increase the gravity of the sliding frame 5 and overcome the elastic force of the spring 7 to move down to the ground at the construction site, thereby fixing the entire baffle 1, and realizing convenient disassembly and installation of the safety enclosure; the baffle 1 is a frame with an opening on one side, and the guide rod 6 and the sliding frame 5 are both located inside the frame of the baffle 1. The warning content on the warning sign 3 can be conveniently replaced, and the warning sign 3 can be flipped and stored inside the baffle 1, thereby improving the convenience of use of the safety enclosure; a plurality of wheels 4 are installed at the bottom of the baffle 1, and the surface of the wheels 4 is a concave-convex pattern. The wheels 4 are all provided with brake parts, and the wheels 4 are used to conveniently push the baffle 1 to move, thereby improving the flexibility of the safety enclosure when it is combined.

[0021] like Figure 1 and Figure 2 As shown, a plurality of card blocks 8 are fixedly provided on the outer wall of one side of the baffle 1, and a socket is opened on the card block 8. A card slot 81 adapted to the card block 8 is provided on the other side of the baffle 1. The multiple baffles 1 can be conveniently spliced ​​together by inserting the card blocks 8 at the head and tail into the corresponding card slots 81. A locking piece is provided on the inner wall of the baffle 1 on one side of the card slot 81. The locking piece is used to lock the card block 8 inserted into the card slot 81 when the baffle 1 is spliced, thereby improving the convenience of assembling the baffle 1 into a safety enclosure.

[0022] like Figure 2 and Figure 4As shown, the locking member includes a wedge block 9, a mounting plate 10 and a second spring 11. The wedge block 9 is provided with two slots 81 symmetrically arranged on the inner wall of the baffle 1, the inclined surface of the wedge block 9 faces the corresponding slot 81 of the baffle 1, the mounting plate 10 is fixed to the inner wall of the baffle 1 near the slot 81, the wedge block 9 is slidably connected to the mounting plate 10 on the same side through the guide rod 6, and the second spring 11 is arranged between the wedge block 9 and the mounting plate 10. After the block 8 is inserted into the slot 81 of another baffle 1, the compressed wedge block 9 causes the second spring 11 to be compressed and then popped out and stuck in the socket of the baffle 1, thereby locking the block 8 and realizing convenient splicing between the two baffles 1.

[0023] like Figure 1 and Figure 4 As shown, it also includes a two-way cylinder 12 and a contact plate 13. The two-way cylinder 12 is installed on one side of the baffle 1 close to the wedge block 9. The contact plates 13 are symmetrically installed on the two-way telescopic rods of the two-way cylinder 12. The contact plates 13 contact and are limited on the corresponding wedge blocks 9. The contact plates 13 are driven by the two-way cylinder 12 to press the corresponding wedge blocks 9. The wedge blocks 9 will compress the spring 11 and release the lock on the card block 8, so that the two baffles 1 can be easily disassembled.

[0024] When it is necessary to set up a safety fence at a highway construction site, first move a single baffle 1 to a predetermined position. Each baffle 1 is equipped with wheels 4 with concave and convex patterns at the bottom. These wheels 4 can not only help workers easily push the baffle 1 to the specified position, but also the brakes on the wheels 4 can ensure that the baffle 1 is stable and motionless after reaching the position. When multiple baffles 1 are placed side by side, the motor 2 installed on one side of the top of the baffle 1 drives the warning sign 3 to rotate along its hinge axis 31, so that the warning sign 3 is flipped out from the inside of the baffle 1 to clearly display the warning information. The content on the warning sign 3 can be easily replaced according to actual needs to adapt to different construction site requirements. In order to quickly and firmly connect multiple baffles 1 to form a continuous safety fence, a plurality of card blocks 8 with sockets are fixed on the outer wall of one side of each baffle 1, and a matching card slot 81 is designed on the other side. When two baffles 1 are docked, the card block 8 at one end can be smoothly inserted When the block 8 is inserted into the slot 81 at the other end, the wedge block 9 will be squeezed first, causing the spring 2 11 to be compressed. Once the block 8 is completely inserted into the slot 81, the spring 2 11 releases energy, pushing the wedge block 9 to reset and make it snap into the socket of the block 8, thereby realizing the rapid locking of the two baffles 1. When multiple baffles 1 are spliced, the operator can add counterweights to the sliding frame 5. As the weight increases, the sliding frame 5 will overcome the resistance of the spring 1 7 between the baffle 1 and the baffle 1 and descend until it touches the ground, further strengthening the position of the baffle 1. If the enclosure needs to be disassembled, it can be done by the two-way cylinder 12 installed on the baffle 1. The two ends of the two-way cylinder 12 are respectively connected to the contact plate 13. When the cylinder is working, the contact plate 13 will push the wedge block 9, so that it can overcome the pressure of the spring 2 11 and withdraw from the socket of the block 8, thereby easily unlocking and separating the two baffles 1. This process is simple and fast, thereby improving the efficiency of disassembly and assembly of the enclosure.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
