Technical Field

[0001] The utility model relates to a concrete geotextile covering machine provided with an extension mechanism, belonging to the technical field of road and bridge construction machinery. Background Art

[0002] After concrete pavement leveling is completed, it needs to be covered with plastic film for curing. Furthermore, to further enhance the curing effect, a geotextile is often laid over the plastic film. Water is sprayed during this process. The application of plastic film and geotextile is now typically performed using specialized machines, significantly improving efficiency compared to traditional methods. In particular, integrated film and geotextile covering machines enable the integrated construction of both film and geotextile coverings.

[0003] However, geotextile covering machines also suffer from poor coverage. Furthermore, in actual construction, the road width at some construction sites varies, rather than being fixed. Beyond the main road surface, there may be areas with gradually varying widths. Traditional machines have a fixed coverage width, making it impossible to cover these additional areas with geotextile coverings. Manual geotextile covering of these areas is highly inconvenient.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] 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", etc., indicating the orientation or position relationship, are based on the orientation or position relationship 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 a limitation on the present invention.

[0033] The utility model relates to a concrete film-covering geotextile machine provided with an extension mechanism. The machine is based on a film-covering and geotextile-covering integrated machine and is provided with an extension mechanism, and can perform mechanized construction operations of film-covering and geotextile-covering on concrete pavements of gradually varying widths.

[0034] 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 entire machine to move longitudinally.

[0035] With the machine's forward direction as the front, the film covering mechanism is placed in front of the geotextile covering mechanism. During construction, the film covering mechanism will apply the film first, followed by 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.

[0036] The machine is equipped with a telescopic paving mechanism, specifically at the two ends of the main truss 1. This mechanism allows paving to be performed on areas beyond the main truss 1, effectively covering areas beyond the main road surface. The adjustable extension length of the mechanism allows paving to be performed on roads with varying widths. Figure 1 and Figure 2 The triangular areas at the two ends represent the road surface with gradually changing width.

[0037] 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.

[0038] like Figure 3 、 Figure 4 As shown, the telescopic and extendable paving mechanism includes a telescopic assembly and a paving assembly positioned at the outer end of the telescopic assembly. The telescopic assembly controls the paving assembly, adjusting its extension range to accommodate gradual road changes and providing power for its movement. The paving assembly is the component that actually performs paving construction, primarily for laying plastic film and geotextiles.

[0039] 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 on the telescopic end at the other end of the telescopic assembly.

[0040] like Figure 4 As shown, the paving assembly primarily comprises a paving support 2 and a paving material mounted on the paving support 2. The paving material is a plastic film 3 or a geotextile 4. The paving material is arranged in a reel-like structure, which is rotated and mounted on the paving support 2 and can be released by rotating during construction. The plastic film 3 and geotextile 4 of the telescopic paving mechanism are rotated and mounted on the paving support 2 using a reel 15.

[0041] In a specific implementation, the covering on the covering support 2 can be a plastic film 3, or a geotextile 4. Typically, the plastic film 3 and the geotextile 4 are simultaneously placed on the covering support 2. When both the plastic film 3 and the geotextile 4 are placed, the geotextile 4 is positioned 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.

[0042] 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 and a plurality of telescopic cylinders 6 that drive 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 level. 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.

[0043] The construction machine of the present invention is provided with a film covering mechanism and a geotextile covering mechanism on the main truss 1. Among them, the film covering mechanism on the main truss 1 includes a plurality of roll-type plastic films 3 and a film pressing shaft 7 arranged along the main truss 1. Specifically, a support beam is provided on the front end side of the main truss 1, and the plastic film 3 is rotated by the roll-up and arranged on the support beam on the front end side of the main truss 1. A film pressing shaft 7 is also provided 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 provided on the front section side of the main truss 1 corresponding to the film covering mechanism. When the construction of laying the plastic film 3 is carried out, water spraying is performed, which can improve the laying effect and promote the curing of the concrete. Specifically, Figure 5 、 Figure 8 shown.

[0044] The geotextile covering mechanism of the present invention is arranged at the rear side of the main truss 1. As a whole, the geotextile covering mechanism is located behind the film covering mechanism, so that the construction sequence of first covering the plastic film 3 and then covering the geotextile is realized.

[0045] like Figure 6 、 Figure 7 As shown, the geotextile covering mechanism includes a geotextile turret 8 fixed to the rear end of the main truss 1 and a rolled geotextile 4. Several rotating rollers 9 are rotatably mounted on the geotextile turret 8. These rollers 9 are arranged in an arc shape, allowing the rolled geotextile 4 to be placed on the arc-shaped rollers 9. The geotextile 4 can rotate on the rotating rollers without falling. Furthermore, a rotatable geotextile guide shaft 10 is located at the rear end of each geotextile turret 8. During geotextile covering, the geotextile 4 passes under the guide shaft 10, which ensures better adhesion to the plastic film 3 and enhances the covering effect. Furthermore, a platform frame 13 is provided at a distance from the rear end of the main truss 1; this platform frame 13 is located behind the geotextile covering mechanism. Typically, both ends of the platform frame 13 are fixedly connected to the rear end of the traveling mechanism. A water sprinkler 11 can be installed 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 the paving effect needs to be checked, the staff can walk on the platform frame 13. The platform frame 13 can be equipped with handrails and other safety protection structures.

[0046] The present invention requires the installation of multiple plastic films 3 and multiple geotextiles 4 to cover a concrete pavement with a relatively long width. Therefore, the plastic films 3 and geotextiles 4 on the main truss 1 are arranged in several rolls along the transverse direction of the main truss 1, and corresponding film covering mechanisms and geotextile covering mechanisms are also provided in multiples. In order to ensure that the pavement is completely covered without any gaps or dead corners, 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, it forms a structure that is staggered in space, 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.

[0047] When the machine is working, the traveling mechanism drives the entire machine to move along the longitudinal direction of the construction road surface, and the film covering mechanism and geotextile covering mechanism on the main truss are attached to the road surface in sequence. At the same time, the telescopic extension paving mechanism works. The outer end of the paving material on the telescopic extension paving mechanism is attached to the outermost end of the widened and gradually changing concrete road surface, and then the telescopic component is retracted, thereby driving the paving material support 1 and the movement of the paving material toward the fixed end of the telescopic component. After the pavement in this area is paved, the main machine moves forward as a whole. 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 extension mechanism repeats the above paving process.

[0048] This utility model is an integrated construction machine for film and geotextile coating during concrete pavement construction, capable of simultaneously performing both film and geotextile coating. Furthermore, a telescopic and extended coating mechanism is provided at the end of the main truss, enabling the coating of additional gradient sections of a road surface with a gradient width. This machine exhibits strong adaptability, a high degree of mechanization, and high construction efficiency.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
