Meanwhile, the terms "upper", "lower", "front", "rear", "middle", and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

The device for fixing the mesh cloth for covering the ditch in road construction as shown in fig. 1 to 3 comprises a pair of L plates 1 and two support rods 2, wherein the L plates 1 comprise vertical plates 11 and flat plates 12. The length of the stay bar 2 can be adjusted, and the two ends of the stay bar are matched with the two standing plates 11. As shown in fig. 2 and 3, a counter bore 111 corresponding to the end of the brace rod 2 is formed in the vertical plate 11, and after the L-plate 1 and the brace rod 2 are assembled, the end of the brace rod 2 is inserted into the counter bore 111. The counter bore 111 may be a stepped bore or a tapered bore, and correspondingly, the end of the strut 2 is stepped or tapered cylindrical. As shown in the figure, the flat plate 12 includes a base plate 121 connected to the vertical plate 11 and a cover plate 122 disposed above the base plate 121. The base plate 121 is provided with a slit 124 extending along the plate surface. The cover plate 122 is provided with a limiting bolt 123, and the end of the limiting bolt 123 can be pressed on the bottom surface of the crack 124 by screwing the limiting bolt 123 to move relative to the cover plate 122. When using the scheme of this patent in the engineering, arrange two L boards 1 in the last port corner or the last port edge of irrigation canals and ditches to make vaulting pole 2 press riser 11 to accomplish fixedly on the cell wall of irrigation canals and ditches through the length of adjustment vaulting pole. After the edge and corner portions of the mesh cloth are inserted into the slits 124, the end portions of the mesh cloth are close to the bottom surface of the slits 124 by screwing the limiting bolts 123, and finally the mesh cloth and the L-shaped plate 1 can be fixedly connected together. If the mesh cloth is directly pressed on the bottom surface of the crack 124 through the limiting bolt 123, a rubber layer is preferably arranged at the end part of the limiting bolt 123, so that the mesh cloth is prevented from being damaged by the limiting bolt after long-term use. And the mesh cloth is pressed on the bottom surface of the crack together through a plurality of limiting bolts, so that the force of the limiting bolts on the mesh cloth is changed into a line, the wind resistance is improved, and the mesh cloth is prevented from being torn and separated from the L plate when the wind power is strong. The stay bar 2 can be a pneumatic or hydraulic lever, or a telescopic rod with a mechanical structure, such as a rod formed by combining a threaded sleeve and a threaded rod, for example, the stay bar comprises three sections of threaded rods and two threaded sleeves, the three sections of threaded rods are connected into a whole through the threaded sleeves, and the length of the stay bar can be adjusted by adjusting the relative screwing lengths of the threaded rods and the threaded sleeves. When the pneumatic cylinder rod structure is selected, the pneumatic cylinder is a double-rod pneumatic cylinder.

As shown in fig. 1, the stay rod 2 includes a middle section and a pair of end rods. The both ends of interlude are equipped with the screw hole, the one end of end pole is equipped with the external screw thread section of screw hole matching on the interlude, the other end of end pole with riser 11 matches, has set up in the drawing that the foot stool card is gone into in the counter bore 111 that sets up on riser 11. The engagement of the foot with the counterbore 111 may require that the foot is not able to rotate relative to the counterbore, which may require that the relative rotation of the two components overcome sufficient resistance to facilitate rotation of the intermediate section to drive the two end rods in opposite directions. If the middle section is rotated clockwise, the two end head rods move towards the left (left end head rod) and the right (right end head rod) and move towards the opposite far direction, and at the moment, the stay bar 2 gradually extends; conversely, rotating the middle section counterclockwise moves the two end rods one to the right (left end rod) and one to the left (right end rod) in a relatively close direction, and the struts 2 are gradually shortened.

As shown in fig. 2 and 3, as a modified embodiment, the upper end surface of the base plate 121 is provided with opposite side walls 121a on the left and right sides, and the slit 124 is oppositely disposed at the lower portion of the side walls 121 a. The cover plate 122 is connected to the upper end of the side wall 121a, and the end of the limiting bolt 123 extends into the cavity formed between the cover plate 122 and the base plate 121 and is provided with a pressing plate 125 in a matching manner. By screwing the limit bolt 123, the pressing plate 125 can be lifted and lowered to selectively bring the pressing plate 125 into contact with or separate from the bottom surface of the nip 124. When the end of the limit bolt 123 is directly and fixedly connected with the pressure plate 125, the cavity formed between the cover plate 122 and the base plate 121 should satisfy the requirement that the pressure plate 125 rotates along with the limit bolt 123 without causing an obstruction to the rotation. Of course, if the pressure plate is connected to the restricting bolt through the bearing structure, and the pressure plate does not rotate together when the restricting bolt rotates, there is no requirement for the size of the cavity as long as the provision of the cavity does not hinder the upward and downward movement of the pressure plate. The mesh cloth is pressed on the bottom surface of the crack 125 by lifting the pressing plate 125, so that the risk that the mesh cloth is torn at the joint position of the L-plate when the mesh cloth is lifted by wind can be better controlled.

One specific embodiment of the connection of the limit bolt 123 to the pressure plate 125 is described below with reference to fig. 2, 3, 5, and 8:

in order to support the above-mentioned structure, a step 121b is provided on the inner side of the side wall 121a, a spring a126 is provided on the step 121b, and grooves (three grooves in a row or two grooves in a row) for fitting the lower ends of the springs a126 are provided on the top surface of the step 121 b. The two sides of the pressing plate 125 corresponding to the step 121b are provided with L-shaped arms, the upper ends of the L-shaped arms press the spring a126, and the spring a126 can lift the pressing plate 125 upwards to separate the pressing plate from the bottom surface of the gap 124. When the limiting bolt 123 is screwed to make the end part relatively close to the bottom surface of the crack 124, the pressing plate 125 can be pressed towards the bottom surface of the crack 124, and finally the lower end surface of the pressing plate 125 is pressed on the bottom surface of the crack 124, so that the elevator cloth is fixedly connected to the L-shaped plate 1. In order to optimize the acting force of the limiting bolt 123 on the pressure plate 125, the end of the limiting bolt 123 is provided with an arched plate 126, the notch of the arched plate 126 faces the pressure plate 125, and the arched plate 126 can act on the upper end face of the pressure plate 125 by screwing the limiting bolt 123. As shown in fig. 2 and 3, the limiting bolt 123 and the arch plate 126 are connected by a column block 128. The lower end of the stud 128 is fixedly connected to the arch 126, and the upper end is inserted into a recess provided in the end face of the limit bolt, so that the stud 128 does not rotate together with the limit bolt 123 when the limit bolt is rotated. If in some embodiments the bolts 123 are defined to be fixedly attached to the arch 126, it is desirable to ensure that the cavity formed between the base plate 121 and the cover plate 122 is able to accommodate the space required for rotation of the arch 126.

In some embodiments, the plate is rotatable in a horizontal plane relative to the riser. Specifically, as shown in fig. 4, a post 112 is disposed on an upper end surface of the vertical plate 11, and an external thread is disposed on an upper portion of the post 112. A second-order stepped counter bore (or a counter bore, at this time, the later mentioned spiral ring is arranged on the upper side relative to the upper end face of the flat plate 11) is arranged on the flat plate 12, and a coaxial through hole is arranged at the bottom of the stepped counter bore. The column rod 112 arranged on the vertical plate 11 penetrates through the upper end of the stepped counter bore. A spring B32 is arranged in the stepped counter bore, and the spring B32 is sleeved on the column rod 112. The spring B32 can push the threaded sleeve 31 disposed at the end of the post 112 to the end of the stepped counterbore, so that the threaded sleeve 31 and the stepped counterbore form a vertical spacing. Thus, the vertical plate 11 is pulled downwards or the flat plate 12 is lifted upwards, so that a space is formed between the lower end surface of the flat plate 12 and the upper end surface of the vertical plate 12, and at the moment, the flat plate 12 can be easily rotated to rotate a certain angle relative to the opposite plate 11. After the external force is removed, the lower end face of the flat plate 12 can be contacted with the upper end face of the vertical plate 12 again under the action of the spring B. In order to ensure that resistance for hindering the relative rotation between the upper end surface of the upright plate 11 and the lower end surface of the flat plate 12 is formed after the upper end surface of the upright plate 11 is contacted with the lower end surface of the flat plate 12, a rubber layer can be arranged on the upper end surface of the upright plate 11 and/or the lower end surface of the flat plate 12 to increase the resistance to the relative rotation. The structure can ensure that the vertical plate 11 is relatively fixed after rotating to any angle relative to the flat plate 12 to a certain extent. The space formed between the vertical plate and the flat plate is not required to be too large, and the vertical plate and the flat plate can be separated from contact.

In some embodiments, it can also be set to position the flat plate relative to the vertical plate after rotating 90 degrees in the horizontal plane. As shown in fig. 6 to 7, positioning posts 113 (two in total) are respectively disposed on two sides of the post 112 on the upper end surface of the vertical plate 11 and in the length direction of the upper end surface of the vertical plate 11. On the lower end surface of the flat plate 11, positioning grooves 121c (four in total) corresponding to the positioning posts 113 are provided on both sides of the through hole. The four positioning grooves 121c are distributed in the relatively vertical radial direction (radial direction of the through hole), and one of the axis connecting lines of every two positioning grooves 121c is consistent with the length direction of the flat plate 12, and the other is consistent with the width direction of the flat plate 12. When the length direction of the upper end surface of upright plate 11 coincides with the width direction of the lower end surface of flat plate 12 (shown in fig. 5), two positioning positions 113 are inserted into two positioning grooves 121c in the up-down direction shown in fig. 6. Conversely, when the width direction of the upper end surface of upright plate 11 coincides with the width direction of the lower end surface of flat plate 12 (shown in fig. 8), two positioning positions 113 are inserted into two positioning grooves 121c in the left-right orientation shown in fig. 6. In a further improvement, in some embodiments, the lower end surface of the flat plate 12 is provided with an annular groove 121d, and the center of the annular groove 121d coincides with the intersection of the axial connecting lines of the positioning grooves 121c arranged in two radial directions. The groove depth of the annular groove 121d is smaller than the depth of the positioning groove 121c, and the groove width of the annular groove 121d is not greater than the inner diameter of the positioning groove 121 c. The upper end surface of the positioning column 113 is provided with a boss matched with the annular groove 121 d. When external force is applied to separate the lower end face of the flat plate from the upper end face of the vertical plate 11, the positioning column 113 gradually moves out of the positioning groove 121c, finally, the boss on the end face of the positioning column 113 moves out of the port of the positioning groove, and the vertical plate can be restrained by the annular groove 121d and walk along the annular groove 121d when being rotated.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. The present invention can be modified in many ways without departing from the spirit and scope of the present invention, and those skilled in the art can modify or change the embodiments described above without departing from the spirit and scope of the present invention.
