Abstract
Description
Technical Field
[0001] This utility model belongs to the field of highway construction technology, specifically relating to an automatic geotextile laying and unlaying device. Background Technology
[0002] In highway pavement base course construction, base course curing is particularly important, and covering with geotextile and watering is a commonly used curing technique. However, traditional geotextile laying and recycling mainly rely on manual rolling and unrolling, which has many shortcomings. Specifically, manual rolling of geotextile is inefficient, consumes a lot of time, and is not conducive to the progress of base course construction. At the same time, controlling the tensile force during manual rolling is a technical challenge. Too little tensile force will cause the geotextile to loosen and wrinkle, causing physical damage, while too much tensile force may cause the geotextile to shift, be incompletely covered, or even tear, all of which will affect the reuse of the geotextile and the quality of base course construction. Secondly, manual unrolling of geotextile also faces many challenges. Since the width of a single roll of geotextile is usually between 5 and 6 meters, inconsistent unrolling speeds at both ends can easily lead to damage to the geotextile. At the same time, geotextile with a single roll length of up to 50 meters makes manual unrolling extremely difficult.
[0003] Currently, although some automatic fabric winding devices exist on the market, these devices are not entirely suitable for the winding needs of geotextiles. Specifically, these devices are too small to accommodate the large dimensions of geotextiles; they fail to effectively compress the geotextile during the winding process, resulting in folding damage; after the geotextile is wound, the winding shaft is difficult to disassemble, reducing the equipment's working efficiency; at the same time, due to friction, it is very difficult to remove the wound geotextile from the shaft; in addition, most winding devices are immobile, making it impossible to perform geotextile winding operations while moving along a road. Utility Model Content
[0004] The purpose of this invention is to provide an automatic geotextile laying and winding device to solve the problem that existing automatic fabric winding and winding devices are difficult to lay and wind up geotextiles.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic geotextile laying and taking-up device, comprising a frame, wherein a pair of ground wheels, an active take-up and take-up wheel and a driven take-up and take-up wheel are rotatably arranged at the bottom of the frame, and a second guide wheel and a second support wheel are rotatably arranged at the top of the frame; a first support wheel and a first guide wheel are rotatably arranged at the front end of the frame; any of the ground wheels and the active take-up and take-up wheel, and the active take-up and take-up wheel and the driven take-up and take-up wheel are connected by chain transmission.
[0006] The technical solution of this utility model also has the following characteristics:
[0007] As a preferred embodiment of this utility model, the frame is further provided with a first limiting wheel and a second limiting wheel.
[0008] As a preferred embodiment of this utility model, both the active take-up and take-up wheels and the driven take-up and take-up wheels are coated with rubber.
[0009] As a preferred embodiment of this utility model, a cleaning mechanism is provided at the rear end of the frame, and the cleaning mechanism is located outside the second guide wheel.
[0010] As a preferred embodiment of this utility model, the cleaning mechanism is a cleaning brush.
[0011] As a preferred technical solution of this utility model, a transition shaft is rotatably provided at the bottom of the frame, and the two ends of the transition shaft are respectively connected to the ground wheel and the active take-up and take-down wheel through chain transmission.
[0012] As a preferred embodiment of this utility model, a pair of limiting rods are provided on the frame.
[0013] The beneficial effects of this utility model are:
[0014] (1) The present invention provides an automatic geotextile winding and laying device, which realizes the winding of geotextile through the friction between geotextile and winding and laying wheel, effectively solving the problem of "soft core" phenomenon of geotextile during winding, and geotextile can be used without threading a shaft.
[0015] (2) The automatic geotextile winding and laying device of this utility model does not require an independent power source. It can move by connecting with a carrier, which solves the problem of tearing and cracking of geotextile caused by the inconsistency between the winding speed and the equipment travel speed.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0021] Example 1
[0022] like Figure 1 As shown, an automatic geotextile laying and taking-up device of this utility model includes a frame 1. The bottom of the frame 1 is rotatably equipped with a pair of ground wheels 9, an active take-up and take-up wheel 11 and a driven take-up and take-up wheel 12. The top of the frame 1 is rotatably equipped with a second guide wheel 3 and a second support wheel 4. The front end of the frame 1 is rotatably equipped with a first support wheel 7 and a first guide wheel 8. The sprocket at one end of any ground wheel 9 is connected to the sprocket at one end of the active take-up and take-up wheel 11, and the sprocket at one end of the active take-up and take-up wheel 11 is connected to the sprocket at one end of the driven take-up and take-up wheel 12 through a chain 14.
[0023] The geotextile is rolled onto a drum. When the geotextile is laid on the road surface, the drum containing the geotextile is placed between the active take-up and release wheel 11 and the driven take-up and release wheel 12, ensuring that one end of the geotextile passes around the outside of the second support wheel 4 and the outside of the first support wheel 7 in sequence and is pressed into the bottom of the ground wheel 9.
[0024] During the laying of geotextile, the ground wheel 9 drives the frame 1 to move forward. While the ground wheel 9 is rotating, it drives the active take-up and release wheel 11 to rotate through the chain 10. The active take-up and release wheel 11 drives the driven take-up and release wheel 12 through the chain 10. The surface of the active (driven) take-up and release wheel generates friction through the friction between the geotextile and the rubber surface, which causes the roll to rotate. The geotextile is gradually unrolled from the roll and the laying work begins. During the forward movement, the ground wheel 9 will flatten the geotextile on the road surface.
[0025] When the geotextile is rolled up, one end of the geotextile on the road is first wrapped around the bottom of the first guide wheel 8, and then wrapped around the outside of the first support wheel 7, the second support wheel 4, and the second guide wheel 3 in sequence, and then connected to the surface of the roll.
[0026] During geotextile winding, as the frame 1 moves forward and the ground wheel 9 rotates, the chain 10 drives the active winding wheel 11 to rotate. The active winding wheel 11 drives the driven winding wheel 12 via the chain 14. The surfaces of the active and driven winding wheels generate friction through the friction between the geotextile and the adhesive surface, causing the roll to rotate. The geotextile gradually unrolls around the pile on the roll and begins the winding process. During the winding process, the first support wheel 7 and the first guide wheel 8 perform preliminary separation and cleaning of sand, gravel, and moisture on the surface of the geotextile.
[0027] Example 2
[0028] like Figure 1 As shown, unlike Embodiment 1, in Embodiment 2, a cleaning mechanism 2 is provided at the rear end of the frame 1 of this utility model for an automatic geotextile laying device. The cleaning mechanism 2 is located outside the second guide wheel 3.
[0029] During the winding process, when the geotextile 6 passes the second guide wheel 3, the cleaning mechanism 2 cleans the sand and gravel on the upper layer of the geotextile.
[0030] Example 3
[0031] like Figure 1 As shown, unlike Embodiment 2, in Embodiment 3, a first limiting wheel 13 and a second limiting wheel 5 are rotatably arranged inside the frame 1. The first limiting wheel 13 and the second limiting wheel 5 are located on both sides of the drum, which can limit the drum from above to prevent it from deviating during rotation.
[0032] Example 4
[0033] like Figure 1 As shown, unlike Embodiment 3, in Embodiment 4, a pair of limiting rods 6 are provided on the frame 1 of this utility model to limit the geotextile and prevent it from deviating during winding and laying.
[0034] Example 5
[0035] like Figure 1 As shown, unlike Embodiment 3, in Embodiment 4, a geotextile automatic laying device of this utility model has a cleaning mechanism 2 at the rear end of the frame 1. The cleaning mechanism 2 is located outside the second guide wheel 3 and is a cleaning brush.
[0036] During the winding process, the cleaning mechanism 2 will further separate and clean the sand and water on the surface of the geotextile.
[0037] Example 6
[0038] like Figure 1As shown, unlike Embodiment 5, in Embodiment 6, an automatic geotextile laying and taking-up device of this utility model has a transition shaft 10 rotatably provided at the bottom of the frame. The two ends of the transition shaft are respectively connected to the ground wheel 9 and the active take-up and take-up wheel 11 through the chain 14.
[0039] The ground wheel 9 and the drive take-up and take-down wheel 11 are equipped with sprockets at their ends, which are connected to the sprockets at both ends of the transition shaft 10 via chain 14.
