Description

Technical Field

[0001] The invention belongs to the technical field of geotextile laying, in particular to a geotextile laying device for river channel construction. Background Art

[0002] Geotextile is a new type of geosynthetics, made of synthetic fibers through needle punching or weaving. The finished product is cloth-like, usually 4-6 meters wide and 50-100 meters long, and some products can even reach 9 meters in width. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles, which have many excellent properties and a wide range of applications.

[0003] In the prior art, the laying of geotextiles is generally divided into two directions. One is to lift the geotextile roll by crane, pull the geotextile manually and unfold it and lay it on the riverbed; the other is to manually fix one end of the geotextile on the riverbed, and then roll the geotextile roll on the riverbed to achieve the purpose of laying. When laying in the above method, manual pulling will cause friction between the geotextile and the riverbed, and the width of the geotextile is large, requiring at least two people to operate synchronously. If the two workers cannot be completely synchronized, the geotextile laid on the riverbed will form wrinkles; the rolling method of the geotextile roll is relatively uncontrollable. When the riverbed is uneven, the geotextile roll will deviate from the predetermined trajectory during the rolling process, thereby affecting the laying, and manual correction is required. Therefore, improvements are made to the above problems. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a geotextile laying device for river construction.

[0008] Preferably, the pressing mechanism includes an arc-shaped rod and a spring. One end of the arc-shaped rod is connected to the pressure roller through a bearing, the other end of the arc-shaped rod penetrates through the first guide frame and is connected with a cutter, and the spring is sleeved on one end of the arc-shaped rod located inside the first guide frame.

[0009] Preferably, the bottom of the cutter is in a sharp angle shape, the sharp angle at the bottom of the cutter is adapted to the second grooves at both ends of the second guide roller, and the opening angle of the first groove in the middle of the second guide roller is larger than the angle of the sharp angle at the bottom of the cutter.

[0010] Preferably, an adjusting mechanism is further arranged on the top of the connecting frame. The adjusting mechanism includes a fixed bracket, a rotating shaft and a movable clamp. The fixed bracket is installed on the top of the connecting frame, the rotating shaft is rotatably connected to the fixed bracket, the movable clamp is slidably connected to one side of the fixed bracket, and the rotating shaft is threadedly connected to the movable clamp.

[0012] Preferably, a first guide roller is further rotatably connected to the support frame. The geotextile roll is led out from the geotextile winding roller, passes under the first guide roller, then covers the top of the second guide roller and extends to the bottom of the pressure roller.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, through the cooperation of the pressure roller and the pressing mechanism, the pressure roller can always have pressure on the ground. The geotextile roll is led out from the geotextile winding roller and finally located under the pressure roller. The pressure roller has pressure on the geotextile.

When the position of the second guide roller changes, the cutter and the second guide roller are sheared, and the height difference between the pressure roller and the rear wheel also changes accordingly, that is, the inclination angle of the river slope changes. In this way, it can adapt to the slope angles of different rivers and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 6As shown, the present invention provides a geotextile laying device for river channel construction, comprising: The driving mechanism 1 includes a fixed platform 101, a front wheel 102, a rear wheel 103 and a support frame 104. The front wheel 102 and the rear wheel 103 are arranged at both ends of the fixed platform 101, and the support frame 104 is symmetrically installed on the top of the fixed platform 101. The driving mechanism 1 also includes a driving motor arranged inside the fixed platform 101 and used to drive the front wheel 102 and the rear wheel 103 to walk along the ground; A geotextile reel 2, which is rotatably connected to the middle of the two support frames 104 and has a geotextile roll disposed on its surface; The connecting mechanism 4 is connected to one side of the fixed platform 101. The connecting mechanism 4 includes a connecting frame 401 and a first guide frame 402. The first guide frame 402 is fixedly connected to the fixed platform 101 through the connecting frame 401; A pressure roller 5, which is rotatably connected to the inside of the first guide frame 402 and is used to press the geotextile; A pressure mechanism 6, which is disposed on the first guide frame 402 and is used to make the pressure roller 5 close to the ground; The synchronous belt 10 drives and connects the rear wheel 103 and the pressure roller 5 .

[0020] By cooperating with the pressure roller 5 and the pressure mechanism 6, the pressure roller 5 can always be under pressure with the ground. The geotextile roll is led out from the geotextile winding roller 2 and finally located under the pressure roller 5. The pressure roller 5 exerts pressure on the geotextile, and under the transmission of the synchronous belt 10, when the driving mechanism 1 moves on the riverbed, the pressure roller 5 also moves synchronously, and the pressure roller 5 and the rear wheel 103 rotate synchronously, that is, when the driving mechanism 1 moves, the geotextile is also laid on the riverbed, and the pressure of the pressure roller 5 on the ground causes the geotextile roll on the geotextile winding roller 2 to be pulled and unfolded, thereby ensuring the stability of the device.

[0021] like Figures 3 to 6 As shown, the connecting mechanism 4 also includes a second guide frame 403, which is fixedly installed on the top of the connecting frame 401, and the second guide roller 8 is movable inside the second guide frame 403 through a bearing; the surface of the second guide roller 8 is annularly provided with a first groove located in the middle and second grooves located at both ends, and the first groove is connected to the second groove; the bottom of the cutter 7 is pointed, and the sharp angle of the bottom of the cutter 7 is matched with the second grooves at both ends of the second guide roller 8, and the opening angle of the first groove in the middle of the second guide roller 8 is greater than the angle of the sharp angle of the bottom of the cutter 7; the first guide roller 3 is also rotatably connected to the support frame 104, and the geotextile roll is led out from the geotextile winding roller 2, passes through the bottom of the first guide roller 3, covers the top of the second guide roller 8 and extends to the bottom of the pressure roller 5.

[0022] Through the cooperation of the cutting knife 7 and the second guiding roller 8, the geotextile can be cut when the device travels to the opposite bank of the river, which is convenient for use. When the device travels to the opposite bank of the river, there is a height difference between the pressing roller 5 and the driving mechanism 1. Under the action of the pressing mechanism 6, the pressing roller 5 maintains the pressure on the ground, and the cutting knife 7 on the pressing mechanism 6 squeezes the geotextile into the first groove, and the geotextile is cut by the shearing force between the cutting knife 7 and the second guiding roller 8. It is worth noting that the width of the first groove is greater than the width of the geotextile, so the geotextile will not enter the second groove, and the second groove is adapted to the cutting knife 7 to limit the cutting knife 7 to ensure stable shearing. The opening angle of the first groove is larger than the angle of the bottom sharp corner of the cutting knife 7. In this way, when the geotextile is cut, the cut part can fall off smoothly and will not be stuck by the cutting knife 7 and the second guiding roller 8, ensuring the use effect of the device.

[0023] As Figure 3 shown, the pressing mechanism 6 includes an arc-shaped rod 601 and a spring 602. One end of the arc-shaped rod 601 is connected to the pressing roller 5 through a bearing, the other end of the arc-shaped rod 601 penetrates through the first guiding frame 402 and is connected with a cutting knife 7, and the spring 602 is sleeved on one end of the arc-shaped rod 601 located inside the first guiding frame 402.

[0024] The arranged spring 602 applies pressure to the pressing roller 5 through its elastic force. Since the arc-shaped rod 601 is connected to the pressing roller 5 through a bearing, when the pressing roller 5 changes its position inside the first guiding frame 402, the position of the cutting knife 7 connected to the arc-shaped rod 601 also changes.

[0025] As Figure 3 shown, an adjusting mechanism 9 is further arranged on the top of the connecting frame 401. The adjusting mechanism 9 includes a fixed bracket 901, a rotating shaft 902 and a movable clamp 903. The fixed bracket 901 is installed on the top of the connecting frame 401, the rotating shaft 902 is rotatably connected to the fixed bracket 901, the movable clamp 903 is slidably connected to one side of the fixed bracket 901 and the rotating shaft 902 is threadedly connected to the movable clamp 903; the movable clamp 903 is in a "C" shape, and both ends of the second guiding roller 8 are rotatably connected inside the opening of the movable clamp 903.

[0026] By rotating the rotating shaft 902, the movable clamp 903 can be driven to move up and down on the side of the fixed bracket 901, thereby driving the second guide roller 8 limited by the movable clamp 903 to move. When the position of the second guide roller 8 changes, the cutter 7 and the second guide roller 8 are sheared, and the height difference between the pressure roller 5 and the rear wheel 103 also changes accordingly, that is, the inclination angle of the river slope changes. In this way, it can adapt to the slope angles of different rivers and has a wide range of applications. It is worth mentioning that when the pressure roller 5 is in any position inside the first guide frame 402, the distance between the pressure roller 5 and the rear wheel 103 is the same, that is, the synchronous belt 10 always maintains the transmission effect, and when the second guide roller 8 is in any position inside the second guide frame 403, the distance between the second guide roller 8 and the rear wheel 103 is also the same.

[0027] The working principle and use process of the present invention: When in use, firstly roll the geotextile on the surface of the geotextile winding roller 2, then lead the geotextile from the geotextile winding roller 2, pass the bottom of the first guide roller 3, cover the top of the second guide roller 8 and extend to the bottom of the pressure roller 5, adjust the rotating shaft 902, so that the second guide roller 8 is at a suitable height, and then start the driving motor. At this time, the front wheel 102 and the rear wheel 103 rotate synchronously, and the pressure roller 5 also rotates with the driving of the synchronous belt 10. Since the spring 602 applies pressure to the pressure roller 5, the pressure roller 5 can press the geotextile and lay the geotextile on the river surface by rotating. At the same time, due to the pressure of the pressure roller 5 on the geotextile, the geotextile roll on the geotextile winding roller 2 is unfolded under the action of tension. At this time, the first guide roller 3 and the second guide roller 8 also rotate accordingly; When the driving mechanism 1 as a whole passes over the river channel slope and the pressure roller 5 is still on the slope, the pressure roller 5 is located below the rear wheel 103 in the height direction. At this time, the arc rod 601 is driven by the pressure roller 5 to move, and the cutter 7 moves with the arc rod 601. During the movement, the cutter 7 squeezes the geotextile and brings the geotextile into the first groove on the surface of the second guide roller 8. The geotextile is sheared by the shear force generated by the squeezing between the cutter 7 and the second guide roller 8.
