On some construction sites, there are additional pavement areas outside the main pavement, and the width of some additional pavement areas is gradual. In this way, traditional machines cannot realize the construction of covering the additional areas with film and geotextile. Utility Model Content
[0004] The purpose of the utility model is to provide a telescopic extension mechanism of a concrete pavement geotextile covering machine, which can adapt to the construction of geotextile covering and geotextile covering on a road surface with gradually changing width, thereby solving the above technical problems.

[0020] 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.
[0021] 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.
[0022] The utility model is a telescopic extension mechanism for a machine for coating geotextiles on concrete pavements. The telescopic extension mechanism is arranged at the end of the machine for coating geotextiles on concrete pavements, and can be used to coat concrete surfaces other than the main pavement with geotextiles. The machine for coating geotextiles on concrete pavements comprises a main truss 2.
[0023] like Figure 1 、 Figure 2 、 Figure 3 As shown, the telescopic extension mechanism mainly includes a telescopic component, a covering support 1 and a covering. One end of the telescopic component is fixedly connected to the main truss 2, and the other end is provided with the covering support 1, on which the covering is arranged.
[0024] Specifically, the telescopic assembly is horizontally arranged, with its fixed end fixedly mounted on the end of the main truss 2. A covering support 1 is fixedly mounted on the telescopic end of the telescopic assembly. The covering is generally a plastic film or geotextile. The covering is rolled and rotated on the covering support 1. The covering can be released by rotating it and then laid on the concrete surface to be cured.
[0025] In a specific implementation, the covering is set to be a plastic film 3, which is wound on a reel 9, and then the rolled plastic film 3 is rotated by the reel 9 and set on the covering support 1. The plastic film 3 rotates with the reel 9 and is released flatly.
[0026] If necessary, the covering can also be a geotextile 4, which is wound on a reel 9 and then rotated on the covering support 1 by the reel 9. The geotextile 4 rotates with the reel 9, thereby achieving the release of the geotextile 4 in a flat manner.
[0027] If the concrete pavement needs to be covered with plastic film and geotextile at the same time, it is necessary to set the plastic film 3 and geotextile 4 on the covering support 1 at the same time. The plastic film 3 and geotextile 4 are both wound on the reel 9. Two positions for installing the reel 9 are set on the covering support 1, and the plastic film 3 and geotextile 4 are rotated and set on the covering support 1 through the reel 9. The geotextile 4 is above the plastic film. During the covering construction, the plastic film 3 is directly covered on the concrete surface, and the geotextile 4 is laid on the surface of the plastic film 3. Specifically, Figure 2shown.
[0028] To improve the paving effect, a rotatable film pressing shaft 5 is installed at the bottom end of the paving support 1. The plastic film 3 and geotextile 4, which are covered by the film pressing shaft 5, pass under the film pressing shaft 5 before being placed on the concrete surface. Furthermore, a number of water sprinklers can be installed on either side of the film pressing shaft 5. These sprinklers spray water onto the concrete surface being paved, and the plastic film and geotextile are immediately applied after the water spraying, thereby improving the curing effect. The water sprinklers are supplied by water pipes. Spraying water also improves the curing effect of concrete.
[0029] The mechanism can also fix a platform frame 6 at the lower end of the covering support 1. If the staff needs to check the covering situation in real time, the staff can stand on the platform frame 6.
[0030] The telescopic extension mechanism drives the movement of the covering support 1 and the covering by the telescopic assembly, thereby achieving the covering of the covering.
[0031] like Figure 1 、 Figure 2 As shown, specifically, the telescopic assembly includes a multi-stage telescopic cylinder and a plurality of telescopic cylinders 8 that drive the telescopic cylinders 7. The multi-stage telescopic cylinder includes a plurality of telescopic cylinders 7 that are sequentially mounted, and the sequential mounting enables mutual connection and coordination, thereby increasing the stroke. The telescopic cylinder 8 has a cylinder barrel and a telescopic rod. The cylinder barrel of the telescopic cylinder 8 is fixed to the outer wall of the telescopic cylinder 7, and the telescopic rod of the telescopic cylinder 8 is fixedly connected to the outer wall of the telescopic cylinder 8 of the next stage. The movement of the telescopic rod of the telescopic cylinder 8 drives the movement and extension of each telescopic cylinder 7. The telescopic cylinder 8 is connected to the hydraulic system of the machine.
[0032] During operation, the telescopic extension mechanism places the outer end of the covering against the concrete pavement. The telescopic assembly then retracts, driving the covering support 1 and the covering toward the fixed end of the telescopic assembly. After the pavement in that area is paved, the main unit moves forward, while the telescopic assembly simultaneously extends the covering support 1 and the covering to their outermost ends. Once the longitudinal movement is complete, the telescopic extension mechanism repeats the paving process.
[0033] The telescopic extension mechanism of the utility model cooperates with a machine for covering a concrete pavement with geotextiles. The telescopic extension mechanism can cover the widened part with plastic film and geotextiles according to the actual width of the widened pavement. The setting of the telescopic component can adapt to the construction of pavements with gradually changing widths.
[0034] 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.
