Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering grid laying, in particular to a glass fiber civil engineering grid laying device. Background Art

[0002] In road construction, fiberglass geogrids are generally used as roadbed reinforcement materials to improve the road's bearing capacity. They are generally laid on the ground using a geogrid laying device. For example, the existing patent number CN217419572U discloses a geogrid laying device that includes a laying frame, a counterweight rod, and multiple guide rollers disposed within the laying frame. The counterweight rod is inserted into a rolled geogrid and placed on the guide rollers. The geogrid can rotate on the guide rollers to achieve unrolling and laying of the geogrid. However, the counterweight rod of the laying device must be fully inserted into the rolled geogrid. After the geogrid is used, the counterweight rod needs to be removed and reinserted into the rolled geogrid. This installation method is not conducive to the rapid replacement of the geogrid. Furthermore, the laying device does not have a downward pressure device, and cannot press down the laid geogrid, causing the laid geogrid to be prone to unevenness or wrinkles, which is not conducive to the tensioning and fixing of the geogrid. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a glass fiber civil engineering grid laying device.

[0004] The technical solution of this utility model is as follows:

[0005] A glass fiber civil engineering grid laying device, comprising:

[0006] The vehicle body is arranged on a reference plane and has a front and a rear portion, the front and the rear portion are distributed along the forward direction of the vehicle body, and running wheels are provided under the vehicle body;

[0007] The support portion is provided on the vehicle body and includes an arc-shaped support plate for placing the rolled earthenware grille. The length direction of the support plate is provided perpendicular to the forward direction of the vehicle body. A first support seat and a second support seat connected to the vehicle body are provided at both ends. The first support seat and the second support seat are provided with an insertion rod on the opposite surfaces. The two insertion rods are coaxially arranged, and the axis direction is coaxial with the axis of the arc-shaped support plate. The insertion rod is located above the arc-shaped support plate. The second support seat is movably connected to the vehicle body and the distance between the second support seat and the first support seat is adjustable.

[0008] The lower pressure part is arranged on the rear side of the vehicle body in the forward direction and on the side of the rolling direction of the rolled civil engineering grille. It includes a lower pressure roller located outside the vehicle body, whose axis direction is parallel to the axis of the insertion rod, and the two ends of the lower pressure roller are respectively connected to the vehicle body through a rotating rod.

[0009] The rolled civil grating is placed on the arc-shaped support plate, and the insertion rods of the first support seat and the second support seat can be inserted into the two ends of the rolled civil grating. In order to facilitate the rapid replacement of the new rolled civil grating, the second support seat is provided to be able to move away from the first support seat so that the new rolled civil grating can be installed between the two insertion rods; a guide roller that can roll on the ground is provided at the rear side of the vehicle. After the civil grating is laid, the guide roller can roll on the civil grating to achieve downward pressure on the civil grating.

[0010] Regarding the second support seat being movable on the vehicle body, the second support seat is elastically connected to the vehicle body through an elastic member, and can slide along the axial direction of the arc-shaped support plate. The elastic member is a tension spring. When a new rolled civil grille needs to be replaced, the second support seat is pulled away from the first support seat, and one end of the new rolled civil grille is inserted into the insertion rod of the first support seat, and the other end is aligned with the insertion rod of the second support seat. The second support seat is released, and the second support seat can be reset under the action of the elastic member.

[0011] In order to facilitate the rotation of the rolled civil grille on the arc support plate, so that the arc support plate can support the rolled civil grille and reduce the bending of the middle part of the longer rolled civil grille, which affects the rotation and feeding, the axes of the two insertion rods are set to be coaxial and parallel to the axis of the arc support plate.

[0012] When the rolled civil grating is rotated and rolled, the middle part is prone to bending. For this reason, the first support seat is symmetrically provided with first guard bars on both sides along the rolling direction. The two first guard bars are located on the outside of the rolled civil grating. The length direction of the first guard bar is parallel to the length direction of the arc support plate and extends toward the middle of the arc support plate. The two first guard bars are located outside the maximum outer diameter that the rolled civil grating can reach.

[0013] Regarding the specific structure of the insertion rod, the insertion rod is a cylindrical insertion rod. In order to facilitate the rolled civil grille to rotate around the insertion rod better and unwind, a sleeve is provided on the outer surface of the insertion rod for rotation, and the sleeve can be inserted into the center hole of the rolled civil grille.

[0014] When the rolled civil grille is unrolled, part of the civil grille will slide over the upper surface of the vehicle body and be laid on the ground. The rear part of the vehicle will inevitably cause wear to the civil grille or affect the sliding of the civil grille. In order to reduce the wear of the civil grille by the rear part of the vehicle, a guide roller is provided on the upper surface close to the rear side. The axial direction of the guide roller is parallel to the axis of the insertion rod. The laid civil grille will contact and slide with the outer cylindrical surface of the guide roller, which is convenient for the unrolling of the civil grille.

[0015] The connection structure between the above-mentioned lower pressure roller and the vehicle body is that the first pin shafts are symmetrically provided on the two opposite sides of the vehicle rear end, the vehicle front and the vehicle rear end are located on the front and rear sides of the vehicle body, and the two first pin shafts are arranged on the left and right sides of the vehicle body, and the axis of the first pin shaft is parallel to the axis of the insertion rod. One end of a single rotating rod is rotatably connected to the end of the lower pressure roller, and the other end is rotatably connected to the first pin shaft, so that the guide roller can rely on gravity to roll the civil engineering grille on the rear side of the vehicle body in the forward direction.

[0016] To facilitate the storage of the guide roller, a sliding groove is provided along the length direction of the rotating rod. The end of the lower pressure roller and the first pin shaft on the same side are both located in the sliding groove. When the guide roller is not used, the guide roller can be connected to the rotating rod and rotated toward the upper surface of the vehicle body so that the guide roller can be placed on the vehicle body.

[0017] When the guide roller is stored as mentioned above, the guide roller will cause pressure loss to the rolled civil grille, and it is inconvenient to store the guide roller. For this reason, a second pin shaft is symmetrically provided on both sides of the vehicle head. The second pin shaft is parallel to the axis of the first pin shaft and is located in the same horizontal plane. One end of the rotating rod is provided with a plug interface adapted to the second pin shaft.

[0018] If the horizontal distance between the first pin and the second pin is greater than the length of the sliding slot, the plug interface will not be plugged into the corresponding second pin. Therefore, the horizontal distance between the first pin and the second pin is set to be smaller than the length of the sliding slot.

[0019] The beneficial effect of the present invention is that, in order to facilitate the rapid replacement of the rolled civil grating, a first support seat and a movable second support seat are provided, the insertion rods on which are located at both ends of the arc-shaped support plate, and the two ends of the rolled civil grating can be respectively inserted into the insertion rods, and the rolled civil grating is supported by the insertion rods, which facilitates the rotation and rolling of the rolled civil grating. When a new rolled civil grating needs to be replaced, the second support seat is moved away from the first support seat, and the new rolled civil grating can be installed, and finally the second support seat is reset;

[0020] In order to press down the civil engineering grille after laying and reduce the unevenness or wrinkles of the civil engineering grille, a guide roller that moves with the vehicle body is set at the rear of the vehicle. The guide roller can be placed directly on the ground. When laying the civil engineering grille, it can roll onto the civil engineering grille and roll it to reduce the wrinkles in the middle or on both sides of the civil engineering grille, facilitate the fixation of the laid civil engineering grille, and improve the laying effect of the fiberglass grille.

[0030] like Figure 1 and Figure 3 The fiberglass civil engineering grid laying device shown in the figure includes a vehicle body 1, a support portion, and a holding portion. The vehicle body 1 is disposed on a reference plane and has a front 101 and a rear 102. The front 101 represents the front side, while the rear 102 represents the rear side. The front 101 and rear 102 are arranged along the forward direction of the vehicle body 1. The vehicle body 1 has an upper surface for mounting a support plate.

[0031] The support portion is provided on the upper surface, and includes an arc-shaped support plate 2 for placing the rolled civil grating 14. The length direction thereof is provided perpendicular to the forward direction of the vehicle body 1, and a first support seat 5 and a second support seat 6 connected to the vehicle body 1 are provided at both ends respectively. The opposite surfaces of the first support seat 5 and the second support seat 6 are provided with an insertion rod 3. The two insertion rods 3 are coaxially provided, and the axial direction is coaxial with the axis of the arc-shaped support plate 2. The insertion rod 3 is located above the arc-shaped support plate 2. The first support seat 5 is fixedly connected to the vehicle body 1, and the second support seat 6 is movably connected to the vehicle body 1. The distance between the second support seat 6 and the first support seat 5 is adjustable. The width of the above-mentioned vehicle body 1 is greater than the length of the arc-shaped support plate 2. As for the specific structure of the insertion rod 3, the insertion rod 3 is a cylindrical insertion rod 3. In order to facilitate the rolled civil grating 14 to rotate better around the insertion rod 3 for unwinding, a sleeve 4 is provided on the outer surface of the insertion rod 3. The sleeve 4 can be inserted into the center hole of the rolled civil grating 14. (See Figure 1 )

[0032] The beneficial effects that can be achieved by the above structure are as follows: the first support seat 5 and the second support seat 6 are respectively arranged on the left and right sides of the vehicle body 1, the arc-shaped support plate 2 is arranged on the upper surface of the vehicle body 1, and the arc direction of the arc-shaped support plate 2 is arranged upward, and the rolled earth grille 14 is placed on the arc-shaped support plate 2, and the middle of the rolled earth grille 14 has a center hole formed by rolling. The insertion rods 3 of the first support seat 5 and the second support seat 6 can be inserted into the two ends of the rolled earth grille 14 to support it, so that the rolled earth grille 14 can be rotated and rolled during laying. In order to facilitate the rapid replacement of the new rolled earth grille 14, the second support seat 6 is arranged to be able to move in the direction away from the first support seat 5, so that the new rolled earth grille 14 can be installed between the two insertion rods 3; in order to reduce the unevenness or wrinkles of the earth grille after laying, a guide roller 11 that can roll on the ground is provided on the rear side of the vehicle tail 102. After the earth grille is laid, the guide roller 11 can roll on the earth grille to achieve downward pressure on the earth grille.

[0033] like Figure 2 As shown, the second support seat 6 can move on the vehicle body 1. The second support seat 6 is elastically connected to the vehicle body 1 through an elastic member 9 and can slide along the axial direction of the arc-shaped support plate 2. The elastic member 9 is a tension spring. When a new rolled earth grille 14 needs to be replaced, the second support seat 6 is pulled away from the first support seat 5. One end of the new rolled earth grille 14 is inserted into the insertion rod 3 of the first support seat 5, and the other end is aligned with the insertion rod 3 of the second support seat 6. The second support seat 6 is released and the second support seat 6 can be reset under the action of the elastic member 9. Specifically, a mounting groove 103 is provided on the side of the vehicle body 1 away from the first support seat 5. The lower end of the second support seat 6 is adapted to the shape of the mounting groove 103. The second support seat 6 is slidably connected to the mounting groove 103 along the length direction of the arc-shaped support plate 2. The second support seat 6 can move in the left and right directions of the vehicle body 1. The tension spring is installed in the mounting groove 103 to connect the second support seat 6 to the mounting groove 103. The axial direction of the tension spring is parallel to the axial direction of the insertion rod 3.

[0034] When the rolled earth grille 14 is rotated and rolled, the middle part is prone to bending. For this reason, the first support seat 5 is provided with first guard bars 10 symmetrically on both sides along the rolling direction. The two first guard bars 10 are located on the outside of the rolled earth grille 14. The length direction of the first guard bar 10 is parallel to the length direction of the arc-shaped support plate 2 and extends toward the middle of the arc-shaped support plate 2. The two first guard bars 10 are located outside the maximum outer diameter that the rolled earth grille 14 can reach. The height of the horizontal plane where the first guard bars 10 are located is not higher than the height of the horizontal plane where the axis of the insertion rod 3 is located. The two first guard bars 10 can support the middle part of the rolled earth grille 14 on both sides, thereby reducing the bending of the rolled earth grille 14 and affecting the rotating rolling. (See Figure 1 and Figure 3 )

[0035] like Figure 1 and Figure 3 As shown, the lower pressure part is arranged on the rear side of the forward direction of the vehicle body 1 and on the side of the feeding direction of the rolled earth grille 14, including a lower pressure roller 7 located outside the vehicle body 1, whose axial direction is parallel to the axis of the insertion rod 3, and the lower pressure roller 7 is provided with a wheel axle along the axial direction, the wheel axle and the lower pressure roller 7 are coaxially arranged, and both ends of the wheel axle pass through the lower pressure roller 7, and the two ends of the wheel axle are respectively connected to the vehicle body 1 for rotation through a rotating rod 8. The connection structure between the above-mentioned lower pressure roller 7 and the vehicle body 1 is that the first pin shafts 12 are symmetrically provided on the opposite sides of the rear end 102, the front end 101 and the rear end 102 are located on the front and rear sides of the vehicle body 1, and the two first pin shafts 12 are arranged on the left and right sides of the vehicle body 1, and the axis of the first pin shaft 12 is parallel to the axis of the insertion rod 3. One end of a single rotating rod 8 is rotatably connected to one end of the wheel axle, and the other end is rotatably connected to the first pin shaft 12. The other rotating rod 8 is arranged similarly. The two rotating rods 8 are symmetrically arranged, so that the guide roller 11 can rely on gravity to roll the civil engineering grille on the rear side of the forward direction of the vehicle body 1.

[0036] To facilitate the storage of the guide roller 11, the rotating rod 8 is provided with a sliding groove 801 along the length direction. The end of the lower pressure roller 7 and the first pin shaft 12 on the same side are both located in the sliding groove 801. When the guide roller 11 is not used, the guide roller 11 can be connected to the rotating rod 8 and rotated toward the upper surface of the vehicle body 1 so that the guide roller 11 can be placed on the vehicle body 1.

[0037] like Figure 6 As shown, when the guide roller 11 is stored, the guide roller 11 needs to be placed on the vehicle body 1. If there is a rolled earth grille 14 that is not in use on the vehicle body 1, the guide roller 11 will cause pressure loss to the rolled earth grille 14, and it is inconvenient to store the guide roller 11. For this reason, second pin shafts 13 are symmetrically provided on both sides of the front of the vehicle 101. The second pin shaft 13 is parallel to the axis of the first pin shaft 12 and is located in the same horizontal plane. One end of the rotating rod 8 is provided with an insertion port 802 that is compatible with the second pin shaft 13. When storing the guide roller 11, it is only necessary to move the end of the rotating rod 8 with the insertion port 802 toward the corresponding second pin shaft 13 and plug it into the second pin shaft 13 to achieve the parallel setting of the rotating rod 8 and the upper surface of the vehicle body 1. Then the guide roller 11 will also be lifted to the side of the rear end 102 for storage. If the horizontal distance between the first pin 12 and the second pin 13 is greater than the length of the sliding slot 801 , the plug-in port 802 will not be plugged into the corresponding second pin 13 . Therefore, the horizontal distance between the first pin 12 and the second pin 13 is set to be smaller than the length of the sliding slot 801 .

[0038] like Figure 4 and Figure 5As shown, when the rolled earth grille 14 is unrolled, part of the earth grille will slide over the upper surface of the vehicle body 1 and be laid on the ground. The rear end 102 will inevitably cause wear to the earth grille or affect the sliding of the earth grille. In order to reduce the wear of the earth grille by the rear end 102, a guide roller 11 is provided on the upper surface close to the rear end 102. The axial direction of the guide roller 11 is parallel to the axis of the insertion rod 3. The laid earth grille will contact and slide with the outer cylindrical surface of the guide roller 11, which facilitates the unrolling of the earth grille and reduces the wear of the earth grille by the rear end 102.
