Description

Technical Field

[0001] This application relates to the technical field of road engineering. Specifically, it relates to a road construction guardrail with noise reduction effect. Background Art

[0002] A road construction guardrail is a facility used to ensure traffic safety during road construction. It is mainly used to isolate the construction area from the traffic lane to protect the safety of construction workers and passing vehicles.

[0003] For example, a road construction guardrail with the patent number (CN220928989U) is characterized in that it includes: a housing, on both sides of which a first guardrail and a second guardrail are slidably embedded. The first guardrail and the second guardrail are slidably inserted into both sides of the housing; the first guardrail and the second guardrail are both provided with columns. Inside the column corresponding to the first guardrail, there are a number of sliding sleeves, and inside the column corresponding to the second guardrail, there are sliding shafts arranged corresponding to the sliding sleeves, and the sliding sleeves are sleeved on the sliding shafts; a fixing member arranged on the top of the housing, which fixes the positions of the first guardrail and the second guardrail when the first guardrail and the second guardrail are adjusted to appropriate positions.

[0004] In the above structure, by slidably embedding the first guardrail and the second guardrail in the housing, pulling out the first guardrail and the second guardrail can adjust the length of the guardrail, and sliding the first guardrail and the second guardrail into the housing is convenient for storing and transporting the guardrail; however, the contraction effect of the guardrail is limited, and the housing still occupies a large space.

[0005] The guardrail in the above structure does not have the function of noise reduction, making it easy to bring noise to surrounding residents and pedestrians during road construction.

[0006] In view of this, the purpose of the present utility model is to provide a road construction guardrail that can be folded and stored and has a noise reduction effect at the same time. Content of the Utility Model

[0024] Further, a first mounting hole is formed through a part of the surface of the noise reduction plate, and a second mounting hole corresponding to the first mounting hole is formed on the connecting rod assembly;

[0025] The fixing member includes a bolt and a nut. The bolt is inserted into the first mounting hole and the second mounting hole, and the nut is in threaded cooperation with the bolt.

[0026] Furthermore, the fixing member further includes a partition ring, which is sleeved on the bolt and disposed at a position between the first mounting hole and the second mounting hole.

[0027] Furthermore, the partition ring includes a long partition ring and a short partition ring, and the length of the long partition ring is greater than that of the short partition ring.

[0028] Furthermore, noise reduction strips are fixedly installed on the side walls of the first fixing rod and the second fixing rod away from each other, and the noise reduction strips are elastic.

[0029] Furthermore, bases are fixedly arranged at the bottoms of the first fixing rod and the second fixing rod, and the bases can be fixedly installed on the ground through expansion bolts.

[0030] The beneficial effects of the present application are as follows:

[0031] 1. Through the mutual articulation of the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod, the first fixing rod and the second fixing rod can freely expand and contract; the setting of the first reinforcing rod and the second reinforcing rod can improve the stability of the connecting rod assembly; when the first fixing rod and the second fixing rod approach each other, the connecting rod assembly automatically folds up, facilitating the handling and storage of the guardrail; by setting the noise reduction plate, the noise during road construction is reduced, and the noise pollution to nearby residents and pedestrians during construction is reduced.

[0032] 2. The noise reduction plate is inserted into the first slot and the second slot, facilitating installation.

[0033] 3. The noise reduction plate is detachably fixedly installed on the connecting rod assembly through the fixing member, which can improve the stability of the noise reduction plate.

[0034] 4. The setting of the partition ring can prevent the noise reduction plate from moving towards the direction close to the connecting rod assembly, further improving the stability of the noise reduction plate. Description of the Drawings

[0054] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence relationship of the functions performed by these devices, modules or units.

[0055] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0056] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0057] A road construction guardrail with a noise reduction effect includes a first fixed rod 1 and a second fixed rod 101. The first fixed rod 1 and the second fixed rod 101 are movably connected by a connecting rod assembly 2. The connecting rod assembly 2 includes a first connecting rod 201 hinged to the top of the first fixed rod 1, a second connecting rod 202 hinged to the bottom of the first fixed rod 1, and the second connecting rod 202 is arranged crosswise with the first connecting rod 201; a third connecting rod 203 hinged to the top of the second fixed rod 1, and one end of the third connecting rod 203 away from the second fixed rod 101 is hinged to one end of the first connecting rod 201 away from the first fixed rod 1; a fourth connecting rod 204 is hinged to the bottom of the second fixed rod 101, and the fourth connecting rod 204 is arranged crosswise with the third connecting rod 203, and one end of the fourth connecting rod 204 away from the second fixed rod 101 is hinged to one end of the second connecting rod 202 away from the first fixed rod 1; when the first fixed rod 1 and the second fixed rod 101 approach each other, the first connecting rod 201 and the second connecting rod 202 rotate towards the direction close to the first fixed rod 1, and the third connecting rod 203 and the fourth connecting rod 204 rotate towards the direction close to the second fixed rod 101, so that the first fixed rod 1 and the second fixed rod 101 can freely approach and separate; the connecting rod assembly 2 further includes a first reinforcing rod 205 and a second reinforcing rod 206. One end of the first reinforcing rod 205 is hinged to one end of the first connecting rod 201 away from the first fixed rod 1, and the other end is hinged to the second connecting rod 202; one end of the second reinforcing rod 206 is hinged to one end of the fourth connecting rod 204 away from the second fixed rod 101, and the other end is hinged to the third connecting rod 203; the settings of the first reinforcing rod 205 and the second reinforcing rod 206 can improve the stability of the connecting rod assembly 2 and at the same time can control the degree of expansion of the connecting rod assembly 2.

[0058] The connecting rod assembly 2 can automatically expand and contract when the first fixed rod 1 and the second fixed rod 101 approach and separate from each other, so as to realize the folding of the guardrail, which is convenient for storing and transporting the guardrail.

[0059] To avoid the impact of road construction on nearby residents and pedestrians, a noise reduction plate 3 is also provided on the guardrail. Specifically, a first insertion plate 102 is fixedly provided on the first fixing rod 1, a first insertion slot 103 is formed in the first insertion plate 102, a second insertion plate 104 is fixedly provided on the second fixing rod 101, a second insertion slot 105 is formed in the second insertion plate 104. The first insertion slot 103 and the second insertion slot 105 extend along the height direction of the first fixing rod 1, and the first insertion slot 103 and the second insertion slot 105 are arranged oppositely. The noise reduction plate 3 is inserted into the first insertion slot 103 and the second insertion slot 105;

[0060] Furthermore, to improve the stability of the noise reduction plate 3, the noise reduction plate 3 and the connecting rod assembly 2 are detachably fixedly connected by a fixing member 4. Specifically, a first mounting hole 401 is formed through a part of the surface of the noise reduction plate 3, a second mounting hole 402 corresponding to the first mounting hole 401 is formed through a part of the surface of the first connecting rod 201. The fixing member 4 includes a bolt 403 and a nut 404. The bolt 403 is inserted into the first mounting hole 401 and the second mounting hole 402, and the nut 404 is in threaded fit connection with the bolt 403. The bolt 403 is a hexagonal bolt 403;

[0061] Since there is a gap between the noise reduction plate 3 and the first connecting rod 201, in order to prevent the noise reduction plate 3 from moving towards the direction close to the first connecting rod 201, a spacer ring 405 is sleeved on the bolt 403, and the spacer ring 405 is arranged at the position between the first connecting rod 201 and the noise reduction plate 3;

[0062] It should be noted that there are multiple first mounting holes 401, and the first mounting holes 401 can be arranged at any position of the noise reduction plate 3. A plurality of second mounting holes 402 corresponding to the first mounting holes 401 are arranged. The second mounting holes 402 are not limited to being arranged on the first connecting rod 201, and can also be arranged on the second connecting rod 202, the third connecting rod 203, the fourth connecting rod 204, the first reinforcing rod 205, and the second reinforcing rod 206;

[0063] Since the distance between the first connecting rod 201 and the noise reduction plate 3 is different from the distance between the second connecting rod 202 and the noise reduction plate 3, to solve this problem, the spacer ring 405 includes a long spacer ring 406 and a short spacer ring 407. The length of the long spacer ring 406 is greater than the length of the short spacer ring 407. The long spacer ring 406 and the short spacer ring 407 are simultaneously sleeved on the bolt 403, or the long spacer ring 406 is sleeved alone, and the short spacer ring 407 is sleeved alone, which can adapt to the distances between different parts of the connecting rod assembly 2 and the noise reduction plate 3.

[0064] Further, in order to improve the stability of the guardrail, a base 106 is provided at the bottom of the first fixing rod 1 and the second fixing rod 101. A support plate 107 connecting the first fixing rod 1 or the second fixing rod 101 is provided on the base 106. The base 106 can be fixedly installed on the ground through expansion bolts 108 to prevent the guardrail from being accidentally knocked down.

[0065] Arranging multiple guardrails at the edge of the construction road can play a role in protection and noise reduction. Since there may be gaps between the guardrails, in order to prevent noise from passing through the gaps between the guardrails, noise reduction strips 5 are fixedly installed on the side walls of the first fixing rod 1 and the second fixing rod 101 that are away from each other. The noise reduction strips 5 are elastic. When the second guardrail is installed on one side of the first guardrail, the noise reduction strip 5 on the first fixing rod 1 of the second guardrail can squeeze the noise reduction strip on the second fixing rod 101 of the first guardrail, thereby preventing sound from passing through the gap between two adjacent guardrails; the material of the noise reduction strip 5 can be polyester fiber, foam plastic, etc.

[0066] The guardrail of this embodiment can form a variety of usage modes according to needs. When only the construction road surface needs to be partitioned and noise reduction is not required, the noise reduction board 3 can be removed, and it only plays a protective role; when temporary noise insulation and reduction are required, the noise reduction board 3 can be inserted into the first slot 103 and the second slot 105; when long-term noise reduction and partitioning are required, the noise reduction board 3 is fixedly connected to the link assembly 2 to improve the stability of the noise reduction board 3.

[0067] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
