Description

Technical Field

[0001] The utility model relates to the technical field of road construction enclosures, and specifically relates to a safety enclosure for highway pavement construction. Background Art

[0002] During the process of highway pavement construction, in order to ensure the safety of construction workers and passing pedestrians, safety enclosures are usually set up to isolate the construction area.

[0003] Most of the traditional safety enclosures adopt fixed structures, and they occupy a large space, which is not conducive to transportation and storage. Especially in projects that require frequent replacement of different construction sections, the limitations of traditional enclosures are particularly obvious. Moreover, when the safety enclosures are idle, the traditional safety enclosures lack an effective stacking mechanism and cannot reasonably utilize the storage space, resulting in low transportation and storage efficiency and increasing the construction cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safety enclosure for highway pavement construction. This device can be stacked, and can reasonably utilize the storage space during storage, improving transportation and storage efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A safety enclosure for highway pavement construction, including a base, a retaining frame is rotatably connected to the top of the base, a cushion block is fixedly connected to one side of the retaining frame, a limiting plate is fixedly connected to the other side of the retaining frame, and the cushion block and the limiting plate are symmetrically distributed about the length direction of the retaining frame.

[0006] With the above structure, after the retaining frame is flipped to a state parallel to the base, this device can be stacked for storage, and can reasonably utilize the storage space during storage, improving transportation and storage efficiency.

[0007] Preferably, when the retaining frame is flipped to the horizontal state, the bottom surface of the cushion block is on the same horizontal plane as the bottom surface of the base, and the upper surface of the retaining frame is on the same horizontal plane as the upper surface of the base.

[0008] With the above structure, the skew during stacking is avoided, and the transportation and storage efficiency is improved.

[0009] Preferably, the limiting plate is in an "L"-shaped plate structure.

[0010] With the above structure, the limiting plate limits the cushion block to prevent the retaining frame from moving randomly after stacking.

[0011] Preferably, a bolt groove is opened on the top surface of the base, a through hole is opened on the bottom surface of the bolt groove, and the bolt groove is in a "U"-shaped groove.

[0012] With the above structure, when the device protects the road surface, it can be connected to the ground using bolts to ensure the stability of the device and prevent it from being moved randomly.

[0013] Preferably, the enclosure frame has a square frame structure, and a plurality of guardrails are fixed in the inner ring opening of the enclosure frame.

[0014] With the above structure, the enclosure frame is strengthened and the cost is saved.

[0015] Preferably, a first hand-tightening screw and a second hand-tightening screw are threaded through the side wall of the base. When the enclosure frame is in a vertical state, the first hand-tightening screw brakes the enclosure frame. When the enclosure frame is in a horizontal state, the second hand-tightening screw brakes the enclosure frame.

[0016] With the above structure, when the device is placed on the road surface, the first hand-tightening screw brakes the enclosure frame to prevent the enclosure frame from tilting. When the device is stacked and stored, it prevents the base from tilting and causing the device to tip over after stacking.

[0017] Preferably, a first positioning hole corresponding to the first hand-tightening screw is provided on the enclosure frame. When the base and the enclosure frame are perpendicular, one end of the first hand-tightening screw is inserted into the first positioning hole; a second positioning hole corresponding to the second hand-tightening screw is provided on the enclosure frame. When the enclosure frame and the base are parallel, the second hand-tightening screw passes through the side wall of the base and is inserted into the second positioning hole.

[0018] With the above structure, the braking effect of the first hand-tightening screw braking the enclosure frame and the second hand-tightening screw braking the enclosure frame is enhanced.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1) The enclosure frame can be rotated flexibly and fixed on the base. At the same time, the first hand-tightening screw is used to brake the enclosure frame, and the installation and disassembly can be quickly completed without complex tools, improving the construction efficiency.

[0021] 2) The self-weight of the base and the screw fixing mechanism ensure the stability of the enclosure during use, effectively preventing the enclosure from being moved or tipped over randomly and ensuring the safety of the construction area.

[0022] 3) The enclosure frame can be rotated to a state parallel to the base and fixed by the second hand-tightening screw, enabling the enclosure to be folded into a flat shape when idle, greatly reducing the occupied space.

[0023] 4) Through the design of the cushion block and the limit plate, multiple folded enclosures can be conveniently stacked together, avoiding skew during the stacking process and improving the transportation and storage efficiency. Description of the Drawings

[0031] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear and understandable, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0032] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a safety enclosure for highway pavement construction, including a base 1, the top of the base 1 is rotatably connected with an enclosure frame 6, an installation groove 3 is opened on the top surface of the base 1, the height of the installation groove 3 is less than the thickness of the base 1, a limiting shaft 4 is fixed between two parallel side walls of the installation groove 3, the limiting shaft 4 penetrates through a through hole 5 opened on the enclosure frame 6, a cushion block 8 is fixedly connected to one side of the enclosure frame 6, a limiting plate 9 is fixedly connected to the other side of the enclosure frame 6, and the cushion block 8 and the limiting plate 9 are symmetrically distributed about the length direction of the enclosure frame 6.

[0033] When the enclosure frame 6 is flipped to the horizontal state, the bottom surface of the cushion block 8 is on the same horizontal plane as the bottom surface of the base 1, and the upper surface of the enclosure frame 6 is on the same horizontal plane as the upper surface of the base 1.

[0034] The limiting plate 9 has an "L"-shaped plate-like structure.

[0035] The top surface of the base 1 is provided with a bolt slot 2 , and the bottom surface of the bolt slot 2 is provided with a through hole, and the bolt slot 2 is a “U”-shaped slot.

[0036] The enclosure frame 6 is a square frame structure, and a plurality of guardrails 7 are fixed in the inner ring opening of the enclosure frame 6.

[0037] The side wall of the base 1 is provided with a hand screw 12 and a hand screw 2 14 through threads. When the enclosure frame 6 is in a vertical state, the hand screw 12 brakes the enclosure frame 6. When the enclosure frame 6 is in a horizontal state, the hand screw 2 14 brakes the enclosure frame 6.

[0038] A positioning hole 11 corresponding to a hand-tightening screw 12 is formed on the enclosure frame 6. When the base 1 and the enclosure frame 6 are perpendicular, one end of the hand-tightening screw 12 is inserted into the positioning hole 11; a positioning hole 2 13 corresponding to a hand-tightening screw 2 14 is formed on the enclosure frame 6. When the enclosure frame 6 and the base 1 are parallel, the hand-tightening screw 2 14 passes through the side wall of the base 1 and is inserted into the positioning hole 2 13.

[0039] Working principle:

[0040] When the base 1 is placed on the road surface, the enclosure plate 1 is in a vertical state, and the staff twists the hand screw 12 to insert it into the positioning hole 11. Due to the weight of the base 1, the base 1 will not be moved at will, that is, when the enclosure frame 6 is vertically perpendicular to the base 1, the base 1 and the enclosure frame 6 cooperate to stand on the road surface to achieve protection of the highway construction area; in order to strengthen the enclosure standing on the road surface, a screw can be used to pass through the through hole at the bottom of the bolt slot 2 to fix the base 1 on the road surface.

[0041] When the enclosure is idle, in order to facilitate the transportation of multiple enclosures after stacking, after screwing the hand screw 12 to disengage it from the positioning hole 11, the enclosure frame 6 is rotated ninety degrees with the limiting axis 4 as the center axis. The enclosure frame 6 is parallel to the base 1, and at this time the top surface of the enclosure frame 6 and the top surface of the base 1 are coplanar. The hand screw 2 14 is screwed and inserted into the positioning hole 2 13 to limit the folded enclosure frame 6. Then, when the two groups of enclosures are stacked, the pad 8 at the bottom of the upper enclosure is inserted into the limiting plate 9 at the top of the lower enclosure to prevent the stacked enclosures from tilting.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
