DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] The invention discloses a concrete geotextile covering machine provided with an extension mechanism. The machine is based on a geotextile covering integrated machine and provided with an extension mechanism, and can carry out mechanized construction operations of geotextile covering on concrete pavements with gradually varying widths.

[0024] like Figure 1 , Figure 2 As shown, the main body of the machine includes a main truss 1, a film covering mechanism and a geotextile covering mechanism arranged on the main truss 1. A walking mechanism 12 is connected to both ends of the main truss 1, and the walking mechanism 12 drives the whole machine to move longitudinally.

[0025] With the machine moving forward as the front, the film covering mechanism is set in front of the geotextile covering mechanism. During construction, the film covering mechanism covers the film first, and the geotextile covering mechanism follows the geotextile covering mechanism. The plastic film is directly attached to the surface of the concrete pavement, and the geotextile is attached to the upper surface of the plastic film.

[0026] The machine is provided with a telescopic and lengthened paving mechanism, specifically, the telescopic and lengthened paving mechanism is arranged at the two ends of the main truss 1. Through the telescopic and lengthened paving mechanism, paving construction is performed on the area outside the main truss 1. That is, paving construction is performed on the area outside the main road surface. The telescopic length of the telescopic and lengthened mechanism can be adjusted, so it can adapt to the paving construction of a road surface with a gradually changing width. Figure 1 and Figure 2 The triangular areas at the two ends represent the road surface with gradually changing width.

[0027] According to actual needs, the telescopic and lengthened covering mechanism can be set at any section of the main truss 1, or the telescopic and lengthened covering mechanism can be set at both ends of the main truss 1 at the same time.

[0028] like Figure 3 , Figure 4 As shown, the telescopic and extended paving mechanism includes a telescopic component and a paving component arranged at the outer end of the telescopic component. The telescopic component is used to control the paving component, and can control the extension range of the paving component to adapt to the gradual road surface. And provide power for the movement of the paving component. The paving component is the part that specifically performs paving construction, mainly capable of paving plastic film and geotextile.

[0029] The two ends of the telescopic assembly are respectively a fixed end and a telescopic end, and the fixed end of the telescopic assembly is fixedly mounted on the end of the main truss 1. A covering assembly is fixedly arranged at the telescopic end at the other end of the telescopic assembly.

[0030] like Figure 4 As shown, the paving assembly mainly includes a paving support 2 and a paving material arranged on the paving support 2. The paving material is a plastic film 3 or a geotextile 4. The paving material is a structure arranged in a reel, and the paving material is arranged on the paving support 2 by rotating the reel, and can be released and opened by rotating during construction. The plastic film 3 and the geotextile 4 of the telescopic and extended paving mechanism are rotated and arranged on the paving support 2 using a reel 15.

[0031] In a specific implementation, the covering on the covering support 2 may be a plastic film 3, or the covering may be a geotextile 4. Generally, the plastic film 3 and the geotextile 4 are simultaneously arranged on the covering support 2. When the plastic film 3 and the geotextile 4 are simultaneously arranged, the geotextile 4 is located above the plastic film 3. The plastic film 3 is directly attached to the concrete pavement, and the geotextile 4 is attached to the plastic film 3.

[0032] like Figure 4 As shown, the telescopic assembly of the present invention preferably adopts a telescopic sleeve type mechanism. Specifically, the telescopic assembly includes a multi-stage telescopic cylinder 5 and a plurality of telescopic cylinders 6 driving the telescopic cylinders 5. Among them, the multi-stage telescopic cylinder includes a plurality of telescopic cylinders 5 that are sequentially mounted, and the sequential mounting realizes mutual connection and coordination, thereby increasing the stroke. The telescopic cylinder 6 has a cylinder barrel and a telescopic rod. The cylinder barrel of the telescopic cylinder 6 is fixed to the outer wall of the telescopic cylinder 5, and the telescopic rod of the telescopic cylinder 6 is fixedly connected to the outer wall of the telescopic cylinder 6 of the next stage. The movement of the telescopic rod of the telescopic cylinder 6 drives the movement and extension of each telescopic cylinder 5. The telescopic cylinder 6 is connected to the hydraulic system of the machine.

[0033] The construction machine of the present invention is provided with a film covering mechanism and a geotextile covering mechanism on the main truss 1. The film covering mechanism on the main truss 1 includes a plurality of reel-type plastic films 3 and a film pressing shaft 7 arranged along the main truss 1. Specifically, a support beam is arranged on the front end side of the main truss 1, and the plastic film 3 is rotated and arranged on the support beam on the front end side of the main truss 1 through a reel. A film pressing shaft 7 is also arranged corresponding to each plastic film 3, and the film pressing shaft 7 is rotatably arranged on the main truss 1. When the plastic film 3 is being laid, the plastic film 3 passes from the lower side of the film pressing shaft 7, so that the plastic film 3 can be better attached to the concrete pavement, thereby improving the laying effect. Furthermore, a plurality of water nozzles 11 are arranged on the front section side of the main truss 1 corresponding to the film covering mechanism, and water spraying is performed when the construction of laying the plastic film 3 is being carried out, which can improve the laying effect and promote the curing of the concrete. Specifically, as Figure 5 , Figure 8 shown.

[0034] The geotextile covering mechanism of the present invention is arranged at the rear side of the main truss 1. On the whole, the geotextile covering mechanism is located behind the film covering mechanism, so as to realize the sequential construction of first covering the plastic film 3 and then covering the geotextile.

[0035] like Figure 6 , Figure 7 As shown, the geotextile covering mechanism includes a geotextile rotating frame 8 fixedly arranged on the rear end face of the main truss 1 and a rolled geotextile 4. A plurality of rotating rollers 9 are rotatably arranged on the geotextile rotating frame 8, and these rotating rollers 9 are arranged in an arc shape as a whole, so that the rolled geotextile 4 can be placed on the rotating rollers 9 arranged in an arc shape. The geotextile 4 can rotate on the rotating rollers without falling off. In addition, a geotextile guide shaft 10 is arranged at the rear end position corresponding to each geotextile rotating frame 8, and the geotextile guide shaft 10 here can rotate. When the geotextile 4 is covered, the geotextile 4 passes from the lower side of the geotextile guide shaft 10, so that the geotextile 4 can be better attached to the plastic film 3, thereby improving the covering effect. Further, a platform frame 13 is arranged at a distance at the rear end of the main truss 1; the platform frame 13 is located at the rear of the geotextile covering mechanism. Generally, the two ends of the platform frame 13 can be fixedly connected to the rear end of the walking mechanism. A water sprinkler 11 can be provided on the front side of the platform frame 13 to spray water on the geotextile to improve the paving effect and the curing effect of the concrete. In addition, if it is necessary to check the paving effect, the staff can walk on the platform frame 13. Safety protection structures such as handrails can be provided on the platform frame 13.

[0036] The present invention requires the provision of multiple plastic films 3 and multiple geotextiles 4 to cover a concrete pavement with a relatively long width. Therefore, the plastic film 3 and geotextile 4 on the main truss 1 are provided with several rolls along the transverse direction of the main truss 1, and multiple corresponding film covering mechanisms and geotextile covering mechanisms are also provided. In order to ensure the complete covering of the pavement without any gaps and dead ends, it is necessary to ensure that adjacent plastic films 3 have areas of staggered and repeated coverage; it is necessary to ensure that adjacent geotextiles 4 have areas of staggered and repeated coverage. Under this structure, when the plastic film 2 of the film covering mechanism is installed on the support beam, a structure that is staggered in space is formed, and the projection on the ground has areas of repeated overlap. The geotextile rotating frame of the geotextile covering mechanism is a structure that is staggered in space, and the projection on the ground also has areas of repeated overlap.

[0037] When the machine is working, the traveling mechanism drives the whole machine to move along the longitudinal direction of the construction road surface, and the film covering mechanism and the geotextile covering mechanism on the main truss are attached to the road surface in turn. At the same time, the telescopic and extended paving mechanism works. The end of the outer end of the paving material on the telescopic and extended paving mechanism is attached to the outermost end of the widened and gradually changing concrete road surface, and then the telescopic component is contracted to drive the paving material support 1 and the movement of the paving material to the fixed end of the telescopic component. After the pavement in this area is paved, the main machine moves forward as a whole, and at the same time, the telescopic component drives the extension of the covering material support 1 and the paving material to the outermost end. After the longitudinal movement is in place, the telescopic and extended mechanism repeats the above paving process.

[0038] The present invention is an integrated construction machine for film and geotextile covering in concrete pavement construction, which can simultaneously carry out film and geotextile covering construction. At the same time, the machine is provided with a telescopic and lengthened covering mechanism at the end of the main truss, which can carry out film and geotextile covering construction on the additional gradual change part of the road surface with a gradual change width, and has strong adaptability, high mechanization degree and high construction efficiency.
