Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway construction technology, and in particular to a material cutting device used in highway construction. Background Technology
[0002] Currently, highway pavements are mainly made of asphalt. However, asphalt pavements are prone to aging, fatigue cracking, and high-temperature deformation. Therefore, during the construction of highways, materials such as fiberglass grids or asphalt self-adhesive mesh are laid on the pavement base layer, and then an asphalt layer is laid and reinforced with reinforcing materials to form an asphalt pavement, which can strengthen the structural performance of the asphalt pavement.
[0003] When laying reinforcing materials such as asphalt self-adhesive mesh on the road surface, in order to make rational use of the materials, it is usually necessary to cut the reinforcing materials such as asphalt self-adhesive mesh according to the road construction conditions. Currently, this step is usually done manually by holding a knife. However, some reinforcing materials have high structural strength and contain steel wires, so cutting such as asphalt self-adhesive mesh reinforcing materials manually is time-consuming and laborious.
[0004] Therefore, we propose a material cutting device for use in highway construction. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art and provide a material cutting device for highway construction.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material cutting device for highway construction, comprising a base, a driving body fixedly installed on the upper surface of the base, two sets of rotatable rollers fixedly installed on the bottom surface of the base, a fixing block fixedly installed on the bottom surface of the base away from the rollers, insert rods provided at both ends of the fixing block, top rods rotatably connected to the outer walls of the two insert rods, and a movable block slidably installed on the bottom surface of the base between the two insert rods, a hydraulic shear fixedly installed on the bottom surface of the movable block, and two sets of symmetrically arranged pressing components installed on the bottom surface of the base between the rollers and the hydraulic shear.
[0007] Preferably, the pressing assembly includes an adjusting rod with one end rotatably connected to the base, and a flattening roller is rotatably mounted on the end of the adjusting rod away from the base.
[0008] Preferably, an adjusting gear is rotatably mounted on the outer wall of the base at a position corresponding to the adjusting rod, and a plurality of equally spaced tooth blocks are fixedly mounted on the outer wall of the adjusting rod near the adjusting gear, and the adjusting gear meshes with the plurality of tooth blocks.
[0009] Preferably, a mounting plate is installed on the fixing block, and two insert rods are respectively located at both ends of the mounting plate, and the insert rods are fixedly connected to the mounting plate.
[0010] Preferably, both ends of the mounting plate are threaded with fixing bolts, and the mounting plate is movably connected to the fixing block through two fixing bolts.
[0011] Preferably, two symmetrically arranged fixing plates are fixedly installed on the bottom surface of the base corresponding to the position of the movable block. A threaded rod is rotatably connected between the two fixing plates. The movable block is located on the outer wall of the threaded rod, and the threaded rod is threadedly connected to the movable block. One end of the threaded rod passes through one of the fixing plates and extends to the outside of the fixing plate. A knob is fixedly installed on the end of the threaded rod located outside the fixing plate.
[0012] Preferably, two sets of symmetrically arranged pull rods are fixedly installed on the outer wall of the base near the roller, and a crossbar is fixedly connected between the ends of the two sets of pull rods away from the base. Beneficial effects
[0013] This utility model provides a material cutting device for highway construction. It has the following advantages:
[0014] (1) The material cutting device used in the construction of this expressway has two upward-curved inserts on the bottom surface of the base. After inserting the end of the insert into the gap between the asphalt self-adhesive net and the road surface, the fixed plate connected to the insert will lift the asphalt self-adhesive net upward. The curvature of the fixed plate is opposite to that of the insert. When the fixed plate rotates upward, the asphalt self-adhesive net can be lifted up, which makes it easier for the hydraulic shears on the bottom surface of the movable block to cut it, so that the size of the asphalt self-adhesive net is more in line with the road conditions.
[0015] (2) The material cutting device used in the construction of the highway can be adjusted by turning the knob to adjust the position of the movable block when the user needs to fine-tune the cutting position of the asphalt self-adhesive mesh cloth. This does not require adjusting the position of the entire device, making the device more flexible in use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-4 As shown, a material cutting device used in highway construction includes a base 3, a drive body 5 fixedly installed on the upper surface of the base 3, two sets of rotatable rollers 4 fixedly installed on the bottom surface of the base 3, a fixing block 8 fixedly installed on the bottom surface of the base 3 away from the rollers 4, and insert rods 11 provided at both ends of the fixing block 8. The outer walls of the two insert rods 11 are rotatably connected to top rods 16, and a movable block 15 is slidably installed on the bottom surface of the base 3 between the two insert rods 11. A hydraulic shear 7 is fixedly installed on the bottom surface of the movable block 15, and two sets of symmetrically arranged pressing components are installed on the bottom surface of the base 3 between the rollers 4 and the hydraulic shear 7.
[0025] In use, the roller 4 rolls to move the device. The ends of the two upward-curved inserts 11 on the bottom surface of the base 3 can be inserted into the gap between the asphalt self-adhesive net and the road surface. The fixed plate 12 connected to the insert 11 rotatably lifts the asphalt self-adhesive net upward. The curvature of the fixed plate 12 is opposite to that of the insert 11. When the fixed plate 12 rotates upward, the asphalt self-adhesive net can be lifted, which makes it easier for the hydraulic shear 7 on the bottom surface of the movable block 15 to cut it, so that the size of the asphalt self-adhesive net is more matched with the road conditions. After the corresponding position on the asphalt self-adhesive net is cut, the two sets of pressing components on the bottom surface of the base 3 can press the asphalt self-adhesive net down to fit the road surface.
[0026] like Figure 1 , 2 and Figure 3 As shown, the pressing assembly includes an adjusting rod 6 with one end rotatably connected to the base 3, and a flattening roller is rotatably mounted on the end of the adjusting rod 6 away from the base 3. When the hydraulic shear 7 starts cutting the asphalt self-adhesive net, the end of the asphalt self-adhesive net is in an upward-curving state, which affects the rolling of the roller 4 in the subsequent process. The flattening roller at the end of the adjusting rod 6 can be used to adjust the end of the asphalt self-adhesive net to be below the flattening roller. Then, the tilt angle of the adjusting rod 6 is adjusted so that the two sides of the asphalt self-adhesive net after cutting are flattened to contact the bottom surface, which facilitates the rolling of the two sets of rollers 4 in the subsequent process.
[0027] like Figure 3 As shown, an adjusting gear 9 is rotatably installed on the outer wall of the base 3 at a position corresponding to the adjusting rod 6. Multiple equally spaced toothed blocks are fixedly installed on the outer wall of the adjusting rod 6 near the adjusting gear 9, and the adjusting gear 9 meshes with the multiple toothed blocks. When the adjusting gear 9 rotates, it can adjust the tilt angle of the adjusting rod 6 by meshing with the multiple toothed blocks. After the hydraulic shear 7 finishes cutting the asphalt self-adhesive net, by adjusting the adjusting rod 6 from horizontal to downward tilt, the asphalt self-adhesive net on both sides of the cutting position can be pressed downward, which facilitates the movement of the roller 4 on the net.
[0028] like Figure 4 As shown, a mounting plate 10 is installed on the fixing block 8, and two insert rods 11 are respectively located at both ends of the mounting plate 10, and the insert rods 11 are fixedly connected to the mounting plate 10; the two insert rods 11 can be installed at both ends of the fixing block 8 by using the mounting plate 10.
[0029] like Figure 4 As shown, both ends of the mounting plate 10 are threaded with fixing bolts 17, and the mounting plate 10 is movably connected to the fixing block 8 through two fixing bolts 17. The mounting plate 10 and the fixing block 8 can be separated by removing the fixing bolts 17. After the insertion rod 11 is worn out after long-term use, the user can remove the mounting plate 10 and replace it.
[0030] like Figure 4 As shown, two symmetrically arranged fixed plates 12 are fixedly installed on the bottom surface of the base 3, corresponding to the position of the movable block 15. A threaded rod 14 is rotatably connected between the two fixed plates 12. The movable block 15 is located on the outer wall of the threaded rod 14, and the threaded rod 14 is threadedly connected to the movable block 15. One end of the threaded rod 14 passes through one of the fixed plates 12 and extends to the outside of the fixed plate 12. A knob 13 is fixedly installed on the end of the threaded rod 14 located outside the fixed plate 12. By rotating the knob 13, the threaded rod 14 can be rotated. Under the action of the threaded transmission between the threaded rod 14 and the movable block 15, the position of the movable block 15 on the threaded rod 14 can be adjusted. When the device is in use, if the user needs to fine-tune the cutting position of the asphalt self-adhesive mesh, the position of the movable block 15 can be adjusted by rotating the knob 13 without adjusting the position of the entire device, making the device more flexible in use.
[0031] like Figure 1 As shown, two sets of symmetrically arranged pull rods 1 are fixedly installed on the outer wall of the base 3 near the roller 4, and a crossbar 2 is fixedly connected between the ends of the two sets of pull rods 1 away from the base 3; the crossbar 2 has a circular cross section. When in use, the user can push the device to move by holding the crossbar 2. The pull rod 1 is relatively long, and the roller 4 is used as the fulcrum, which makes the device easier to use.
[0032] The working principle of this utility model is as follows: During use, the roller 4 rotates, which drives the device to move. Two upwardly curved inserts 11 are provided on the bottom surface of the base 3. The ends of the inserts 11 are inserted into the gap between the asphalt self-adhesive net and the road surface. The fixed plate 12, rotatably connected to the inserts 11, then lifts the asphalt self-adhesive net upwards. The curvature of the fixed plate 12 is opposite to that of the inserts 11. When the fixed plate 12 rotates upwards, the asphalt self-adhesive net is lifted, making it easier for the hydraulic shears 7 on the bottom surface of the movable block 15 to cut it, thus making the size of the asphalt self-adhesive net more suitable for the road conditions. Rotating the knob 13 drives the threaded rod 14 to rotate. The movable block 15 can be adjusted by the threaded transmission between the threaded rod 14 and the movable block 15. When the device is in use, if the user needs to fine-tune the cutting position of the asphalt self-adhesive mesh, the position of the movable block 15 can be adjusted by turning the knob 13 without adjusting the position of the entire device, making the device more flexible in use. In the process of use, the user can push the device to move by holding the crossbar 2. The pull rod 1 is relatively long, and the roller 4 is used as the fulcrum, which makes it easier to insert the insertion rod 11 set on the bottom surface of the base 3 into the gap between the asphalt self-adhesive mesh and the road surface.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
