Description

Technical Field

[0001] The utility model relates to the field of municipal engineering, and specifically relates to an auxiliary device for laying coal gangue on expressways. Background Technique

[0002] There are mainly the following reasons for using coal gangue to pave expressways: Resource utilization: Coal gangue is a waste generated during coal mining and processing. If not utilized, it will occupy a large amount of land and cause environmental pollution; Using it for expressway paving realizes the resource utilization of waste and reduces land occupation; For example, in some areas rich in coal resources, coal gangue piles up like mountains. By applying it to road construction, this problem has been effectively solved; Cost reduction: Compared with traditional road construction materials, the acquisition cost of coal gangue is relatively low, which can reduce the cost of expressway construction to a certain extent; For example, purchasing high-quality stone materials as road paving materials is often expensive, while using coal gangue can save capital investment; Performance advantages: Appropriately treated coal gangue has certain engineering properties, such as compressive strength, stability, etc., which can meet the basic requirements of expressways; For example, in some areas, through experiments and practices, it has been proved that the expressway sections paved with coal gangue perform well in terms of bearing capacity and durability.

[0003] During the construction of expressways, when coal gangue is used as the base layer and laid manually, it is very difficult to make its surface flat by relying on manual observation. Subsequently, it may lead to uneven thickness of the upper asphalt or cement concrete surface layer. The thin places are prone to early damage, such as cracking and peeling; For example, cracks will quickly appear in the thin part of the surface layer under the repeated action of vehicle loads and gradually expand; It affects the flatness of the surface layer and greatly reduces the driving comfort of the expressway.

[0004] Currently, the flatness of coal gangue laying is usually judged by a flatness detection device after laying. For example, the Chinese utility model patent with the application number 202220142913.7 provides a subgrade and pavement flatness detection device, which automatically detects the flatness of the road surface, replaces the artificial observation of the level measuring ruler, and improves the detection accuracy.

[0005] However, the usual practice is to conduct flatness detection after laying, which has problems such as rework and material waste, and cannot guarantee the flatness during the laying of coal gangue, resulting in low efficiency of coal gangue laying on expressways and not meeting the actual laying requirements. Content of the Utility Model

[0006] The purpose of the utility model is to provide an auxiliary device for laying coal gangue on expressways to solve the technical problem that the existing coal gangue on expressways cannot be laid flat.

The specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Specific details such as specific system structures and technologies are proposed to more thoroughly understand the embodiments of the present utility model. The described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. However, those skilled in the art should understand that the present utility model can also be implemented in other embodiments without these specific details. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model disclosure.

[0028] The following details the specific implementation manners of the present utility model in conjunction with the accompanying drawings.

[0029] Please refer to Figures 1-5 , the present utility model provides an auxiliary device for laying coal gangue on highways, including a first auxiliary frame 1, a second auxiliary frame 2 and a horizontal calibration mechanism. The horizontal calibration mechanism can perform horizontal calibration by using a light source. The horizontal calibration mechanism includes a transmitting member provided on the first auxiliary frame 1 and a receiving member 3 provided on the second auxiliary frame 2. The transmitting member and the receiving member 3 are facing each other. The transmitting member is used to emit visible light, and the receiving member 3 is used to receive visible light. By adjusting the heights of the first auxiliary frame 1 and the second auxiliary frame 2, when the light spot irradiated by the center point of the transmitting member falls on the center of the receiving member 3, the laying flatness of the coal gangue on both sides of the highway is ensured.

[0030] The transmitting member includes an installation cylinder 17 and a laser lamp 18. The laser lamp 18 is movably connected to the first auxiliary frame 1 through the installation cylinder 17, and the laser lamp 18 is rotatably connected to the installation cylinder 17. Preferably, the laser lamp 18 can rotate up and down in the installation cylinder 17 around the horizontal axis.

[0031] Specifically, during actual use, place the first auxiliary frame 1 on one side of the highway pavement to be laid, place the second auxiliary frame 2 on the other side of the highway pavement to be laid, start the transmitting member, adjust the height of the first auxiliary frame 1 according to the laying thickness of the coal gangue, and then adjust the height of the second auxiliary frame 2. The laser lamp 18 is horizontally arranged so that the light spot emitted by the laser lamp falls on the middle position of the receiving member 3, then the adjustment of the horizontal reference for laying the coal gangue is completed. Subsequently, when laying the coal gangue, lay it according to the adjusted horizontal reference, which improves the flatness after laying the coal gangue.

[0032] To meet the laying requirements, the length of the first auxiliary frame 1 and that of the second auxiliary frame 2 can both be selected from 3m to 5m. At this time, both the receiving member 3 and the transmitting member can be selected as multiple. The multiple transmitting members are arranged at equal intervals along the length direction of the first auxiliary frame 1, while the receiving member 3 is arranged along the length of the second auxiliary frame 2, and the receiving member 3 and the transmitting member are arranged in a one-to-one facing manner.

[0033] Furthermore, since the laying thickness requirements of different highways are different, the first auxiliary frame 1 and the second auxiliary frame 2 are both preferably of a telescopic structure.

[0034] The first auxiliary frame 1 includes a first calibration piece 15 and a first support frame. The first calibration piece 15 is installed on the first support frame, and the first calibration piece 15 is telescopically connected to the first support frame up and down. The mounting cylinders 17 are arranged at equal intervals along the length of the first calibration piece 15.

[0035] Similarly, the second auxiliary frame 2 includes a second calibration piece and a second support frame. The second calibration piece is installed on the second support frame, and the second calibration piece is telescopically connected to the second support frame up and down. The receiving members 3 are arranged at equal intervals along the length of the second calibration piece.

[0036] During actual use, according to the requirement of the laying thickness of coal gangue on the highway, the laying thickness of coal gangue can be determined based on the height between the reference line horizontally irradiated by the laser lamp 18 and the highway pavement to be laid. Subsequently, the height of the second calibration piece is adjusted so that the laser lamp 18 is directly opposite to the corresponding receiving member 3.

[0037] Specifically, the first calibration piece 15 and the first support frame can be telescopically connected by means of electric lifting or hydraulic lifting and other structures. Preferably, a first adjusting column 16 is provided at the bottom of the first calibration piece 15, and a vertically arranged first adjusting hole 19 is opened on the first support frame. The first adjusting column 16 cooperates with the first adjusting hole 19, and by adjusting the insertion depth of the first adjusting column 16 in the first adjusting hole 19, the height of the first calibration piece 15 can be adjusted, which is simple and convenient to operate.

[0038] Similarly, a second adjusting column is provided at the bottom of the second calibration piece, and a second adjusting hole is opened on the second support frame. The height of the second calibration piece is adjusted by using the cooperation between the second adjusting column and the second adjusting hole.

[0039] Among them, the first support frame includes a first bottom plate 11 and a first vertical plate 13. The first bottom plate 11 and the first vertical plate 13 are perpendicularly arranged to form a T-shaped structure. The first adjusting hole 19 is opened on the first vertical plate 13. Preferably, the number of the first adjusting holes 19 is two, and the two first adjusting holes 19 are located on the opposite sides of the first vertical plate 13; the first bottom plate 11 is used to provide stable support.

[0040] Similarly, the second support frame includes a second bottom plate and a second vertical plate. The second bottom plate and the second vertical plate are perpendicularly arranged to form a T-shaped structure. The second adjustment holes are formed in the second vertical plate, and the number of the second adjustment holes is two. The two second adjustment holes are formed on the opposite sides of the second vertical plate. The second bottom plate is used to provide stable support.

[0041] Adjustment grooves are formed on the side walls of the first adjustment hole 19 and the side walls of the second adjustment holes. The adjustment grooves are vertically arranged. Studs 14 are arranged on both the first adjustment column 16 and the second adjustment column. The end of the stud 14 on the first auxiliary frame 1 extends from the first adjustment column 16 through the adjustment groove to the outside of the first adjustment hole 19. The end of the stud 14 on the second auxiliary frame 2 extends from the second adjustment column through the adjustment groove to the outside of the second adjustment hole. After adjusting the heights of the first calibration piece 15 and the second calibration piece, nuts are arranged on the studs 14 and tightened to prevent loosening.

[0042] In order to reduce the weight for handling, weight reduction holes 12 are selected to be formed in the first bottom plate 11 and the second bottom plate, so as to reduce the overall weight and facilitate transportation and handling.

[0043] When there is a bend during the laying process of the highway, the road surface design has an angle with the horizontal direction. At this time, the height of the first calibration piece 15 can be determined according to the laying thickness of the coal gangue. According to the road surface width a, the height b of the first calibration piece 15, and the size of the road surface angle α, the height h of the second calibration piece is calculated through trigonometric functions, h = a × tanα + b. At this time, it is preferably to arrange height scales on both the first adjustment column 16 and the second adjustment column to facilitate accurately adjusting the height of the second calibration piece. Finally, the angle of the laser lamp 18 is adjusted so that the light spot of the laser lamp 18 irradiates on the center position of the receiving member 3, and then the adjustment of the horizontal reference is completed. The coal gangue is laid according to the adjusted horizontal reference, so as to ensure the requirement of uniform laying thickness of the coal gangue for the highway and further meet the actual laying requirements.
