Abstract
Description
Technical Field
[0001] This utility model relates to the field of building marking equipment technology, specifically to a marking device for the surface of earth and rock dams. Background Technology
[0002] During the construction and marking of lines on the surface of an earth-rock dam, the process of marking the horizontal axis is as follows: after the ink line is dipped in ink, the ink line is stretched taut on the slope of the earth-rock dam to complete the marking. This process is also called snapping the line. When pulling up the taut ink line, it is necessary to pull the ink line in a direction perpendicular to the dam surface.
[0003] Currently, because the surface of an earth-rock dam has a certain slope, if the ink line is not perpendicular to the ground and the slope of the dam surface when marking the lines, it will cause a large error when the ink is applied to the dam surface, which will make it difficult to accurately position the construction lines on the dam surface. Utility Model Content
[0004] The purpose of this utility model is to provide a marking tool for earth-rock dam surfaces, reducing errors when marking lines on earth-rock dam surfaces.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A marking tool for the surface of an earth-rock dam includes an alignment plate with fixing components installed at both ends. A connecting plate is hinged to the alignment plate, and the connecting plate has a connecting hole for connecting the ink line. It also includes a vertical rod with its lower end connected to the alignment plate and a top plate installed on its top. A positioning rod is also included, with one end connected to the upper end of the vertical rod via a rotating ring, and the other end having a through hole. A sliding rod is slidably connected within the through hole, and the lower end of the sliding rod is connected to a fixing rod. The fixing rod is hinged to a pair of clamping blocks via a rotating rod, the clamping blocks being used to clamp the ink line. An insert rod is also included, passing through the positioning rod. The upper end of the insert rod is connected to the top plate, and the connecting plate has a mating groove, with the lower end of the insert rod engaging with the mating groove. Finally, a sliding sleeve is included, slidably connected to the outside of the sliding rod, located above the clamping blocks. Pull ropes are provided on the left and right sides of the sliding sleeve, respectively connected to the left and right ends of the clamping blocks, so that the clamping blocks separate when the sliding sleeve moves upward.
[0007] Furthermore, the positioning rod includes a first positioning rod section and a second positioning rod section. One end of the first positioning rod section is installed on the upright, and the through hole is provided on the second positioning rod section. The first positioning rod section and the second positioning rod section are hinged together by a hinge block.
[0008] Furthermore, a pull ring is installed at the upper end of the slide rod.
[0009] Furthermore, a support block is provided on the side of the slide rod, and a clearance channel is provided on one side of the through hole for the support block to pass through; a support groove is provided on the other side of the through hole for engaging the support block.
[0010] Furthermore, the fastener includes a positioning groove and a pin.
[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0012] The uprights are slidably connected through the perforations on the positioning rods, which ensures that the sliding direction of the positioning rods is always perpendicular to the mounting surface of the alignment plate, i.e., the dam surface. After the alignment plate is fixed, the rebound direction of the ink line is restricted and always perpendicular to the dam surface. Even when drawing lines on an inclined dam surface, errors can be reduced and the accuracy of the lines can be ensured. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a marking tool for the surface of an earth-rock dam includes an alignment plate 1, with fixing components installed at both ends of the alignment plate 1. A connecting plate 12 is hinged to the alignment plate 1, and the connecting plate 12 has a connecting hole 13 for connecting the ink line. It also includes a vertical rod 23, the lower end of which is connected to the alignment plate 1, and a top plate 25 is installed on the top of the vertical rod 23. Furthermore, it includes a positioning rod, one end of which is connected to the upper end of the vertical rod 23 via a rotating ring 24, and the other end has a through hole 33. A sliding rod 34 is slidably connected within the through hole 33, and the lower end of the sliding rod 34 is connected to a fixing rod 36. The fixing rod 36 is connected to the rotating rod 36 via the rotating rod 36. A pair of clamping blocks 37 are hinged together, which are used to clamp the ink line; it also includes a plug rod 26, which passes through the positioning rod and whose upper end is connected to the top plate 25. The connecting plate 12 is provided with a docking groove 121, and the lower end of the plug rod 26 is engaged with the docking groove 121; it also includes a sliding sleeve 35, which is slidably connected to the outside of the sliding rod 34. The sliding sleeve 35 is located above the clamping blocks 37, and pull ropes 351 are respectively provided on the left and right sides of the sliding sleeve 35. The pull ropes 351 on the left and right sides are respectively connected to the left and right ends of the clamping blocks 37, so that the clamping blocks 37 are separated when the sliding sleeve 35 moves upward.
[0021] The working process of this utility model is as follows: The alignment plate 1 is fixed to the dam surface using the fixing structures at both ends, ensuring that the alignment plate 1 corresponds to the horizontal line on the dam surface, so that the horizontal and vertical axes remain perpendicular during line marking. One end of the ink line is connected to the connecting hole 13 of the connecting plate 12. Then, the ink line is taut according to the desired line marking position. Since the connecting plate 12 is hinged to the alignment plate 1, it automatically adjusts its orientation according to the taut direction of the ink line during tautness. Because the insertion rod 26 passes through the positioning rod and connects to the connecting plate 12, the positioning rod and the taut ink line are always aligned, ensuring that the upright rod 23 is always directly above the ink line. After tautness, the ink line is clamped by the clamping block 37 at the lower end of the upright rod 23. After raising it to a certain height, the sliding sleeve 35 is slid upwards, causing the sliding sleeve 35 to pull the clamping block 37 apart via the pull rope 351, allowing the ink line to spring back to the dam surface, completing the line marking process. The upright 23 is slidably connected through the through hole 33 on the positioning rod, which can ensure that the sliding direction of the positioning rod is always perpendicular to the mounting surface of the alignment plate 1, i.e. the dam surface. After the alignment plate 1 is fixed, the rebound direction of the ink line is restricted and always perpendicular to the dam surface. Even when drawing lines on an inclined dam surface, errors can be reduced and the accuracy of the drawing can be ensured.
[0022] Furthermore, the positioning rod includes a first positioning rod section 3 and a second positioning rod section 31. One end of the first positioning rod section 3 is mounted on the upright 23, and the through hole 33 is provided on the second positioning rod section 31. The first positioning rod section 3 and the second positioning rod section 31 are hinged together by a hinge block 32. With the through hole 33 on the second positioning rod section 31, during the process of sliding the upright 23 and pulling the ink line, the second positioning rod section 31 can also rise to a certain height through its own rotation, thereby allowing the clamping point of the clamping block 37 to clamp the ink line to rise to a higher height, ensuring sufficient elasticity during the ink line's springing process.
[0023] Furthermore, a pull ring 342 is installed at the upper end of the slide bar 34 to facilitate the operation of the upright pole 23 by the staff.
[0024] Furthermore, a support block 341 is provided on the side of the sliding rod 34, and a clearance channel 331 is provided on one side of the through hole 33 for the support block 341 to pass through; a support groove 332 is provided on the other side of the through hole 33 for engaging the support block 341. By setting the support block 341 and adjusting the position of the support groove 332 by rotating the upright rod 23, the support block 341 can pass smoothly through the clearance channel 331 when the upright rod 23 moves. It can also suspend the upright rod 23 by engaging the support block 341 in the support groove 332, thus preventing the bottom of the upright rod 23 from being on the dam surface and affecting the alignment of the ink line when positioning it.
[0025] like Figure 4 As shown, further, the alignment plate 1 is provided with an installation groove 11, and the connecting plate 12 is hinged in the installation groove 11. Limiting grooves 14 and protrusions 261 are respectively provided on both sides of the installation groove 11. It also includes an installation plate 2, which is fixedly connected to the lower end of the upright 23. The two ends of the installation plate 2 are respectively provided with a pressing rod 21 and a slot. The pressing rod 21 is used to engage the limiting groove 14, and the slot is used to engage the protrusion 261, so that the positioning plate and the installation plate 2 can be detachably connected.
[0026] Furthermore, the pressing rod 21 passes through the mounting plate 2 and is slidably connected to the mounting plate 2. A spring 22 is sleeved on the outer side of the pressing rod 21; one end of the spring 22 is connected to the pressing rod 21, and the other end is connected to the mounting plate 2. The spring 22 provides elastic force to compress and limit the mounting plate 2.
[0027] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
[0028] Furthermore, the fixing component includes a positioning groove 15 and a pin 151. The positioning groove 15 at both ends of the alignment plate 1 facilitates the alignment plate 1 to correspond with the vertical line of the dam surface. The pin 151 is used to allow the alignment plate 1 to be inserted and fixed on the dam surface, so that the position of the alignment plate 1 can be fixed when the position needs to be fixed.
