Technical Field

[0001] This utility model relates to the technical field of cutting devices for asphalt waterproof membranes, and in particular to a cutting device for modified asphalt waterproof membranes for roads and bridges. Background Technology

[0002] Roads and bridges are a collective term for roads and bridges, and are a key component of transportation infrastructure construction. During the construction of roads and bridges, cutting devices are often used to cut asphalt waterproof membranes to improve construction efficiency.

[0003] Existing technologies, such as the utility model patent with publication number CN217102409U, disclose a cutting device for modified bitumen waterproof membrane for roads and bridges. This patent uses an installation platform, on the surface of which a pressure frame and a winding frame are installed. The surface of the installation platform is provided with a limiting device, which includes a fixing frame. The fixing frame is fixedly connected to the surface of the installation platform. The surface of the fixing frame has a sliding hole, and a slide is slidably connected to the inner wall of the sliding hole. A fixing plate is slidably connected to the end of the slide near the installation platform. A cutting blade is fixedly connected to the side of the fixing plate near the installation platform, and a fixing block is fixedly connected to the side of the fixing plate away from the cutting blade. This solves the problem in the prior art that the cutting machine can only cut specific types of membranes.

[0004] In the process of cutting roll materials using a cutting device, there is a problem that when using existing cutting devices such as those mentioned above, the roll material is often placed directly in the cutting area for cutting. Due to the large force generated during the cutting process, when the roll material is simply placed in the cutting area, the force generated during cutting will push the roll material to move, resulting in the deviation of the cut and a reduction in cutting accuracy. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the force generated during the cutting process is too large, and when the roll material is simply placed in the cutting area, the force generated during cutting will push the roll material to move, resulting in the deviation of the cut and the reduction of cutting accuracy. Therefore, a cutting device for modified bitumen waterproof roll material for road and bridge is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for modified asphalt waterproof membrane for road and bridge construction, comprising a base, a placement frame, and a support. The placement frame is fixedly connected to the upper surface of the base, and the support is fixedly connected to the upper surface of the base. A driving mechanism is installed at the upper end of the support, and the driving end of the driving mechanism is located inside the support. A movable frame is slidably connected to the inner wall of the support, and the movable frame is threadedly connected to the driving end of the driving mechanism. A cylinder is fixedly connected to the lower surface of the movable frame, and a cutting blade is installed at the driving end of the cylinder. A clamping assembly is provided at the connection between the support and the base.

[0007] The clamping assembly includes a guide rail, which is fixedly connected to the side surface of the bracket. A slider is slidably connected to the surface of the guide rail, and a connecting plate is fixedly connected to the surface of the slider. Clamping plates are fixedly connected to both the front and rear sides of the connecting plate.

A servo motor is fixedly connected to the left side of the guide frame, and a bidirectional lead screw is installed at the drive end of the servo motor. A connecting frame is slidably connected inside the guide frame, and a threaded sleeve is fixedly connected to the outer side of the connecting frame. The threaded sleeve is threadedly connected to the surface of the bidirectional lead screw. A linkage frame is fixedly connected to the side of the connecting frame near the connecting plate, and the linkage frame is slidably connected to the surface of the protrusion.

[0009] Preferably, the slider is in contact with the side surface of the bracket, and the connecting plate is in contact with the side surface of the bracket. Through the cooperation of the slider and the guide rail, the movement direction of the connecting plate can be guided to ensure that the connecting plate moves in a specified direction and reduce the offset of the connecting plate during the movement.

[0010] Preferably, the clamping plate is L-shaped and contacts the side surface of the base. The clamping plate can move downward under the action of the connecting plate and press the roll material on the base through the protruding part located above the base, thereby cooperating with the base to clamp and lock the position of the roll material.

[0011] Preferably, the lower inner wall of the connecting plate base is in contact with the connecting plate, and the protrusion and the connecting plate can be connected through the connecting plate so that when the protrusion is pushed by the linkage frame, the connecting plate can be moved by the protrusion.

[0012] Preferably, the protrusion is cylindrical, and the protrusion can push the connecting plate downward along the slot direction of the linkage frame during the movement of the linkage frame, so that the connecting plate can pull the connecting plate downward.

[0013] Preferably, the bidirectional lead screw is rotatably connected to the inner wall of the guide frame. Driven by a servo motor, the bidirectional lead screw can engage with the threaded sleeves on both sides, thereby driving the connecting frame to move.

[0014] Preferably, the linkage frame is in contact with the side surface of the connecting plate, and the slot of the linkage frame is inclined. The linkage frame can push the protrusion under the drive of the connecting frame, so that the protrusion can pull the connecting plate downward.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up a clamping component, the equipment can clamp the roll material in the processing area during processing, thereby reducing the problem of the roll material shifting during the cutting process and causing a decrease in cutting accuracy, and further improving the cutting accuracy of the cutting device and the constraint on the roll material.

Detailed Implementation

[0025] Please see Figures 1-6 This utility model provides a technical solution: a cutting device for modified asphalt waterproof membrane for road and bridge construction, including a base 1, a placement frame 2 and a support 3. The placement frame 2 is fixedly connected to the upper surface of the base 1, and the support 3 is fixedly connected to the upper surface of the base 1. A driving mechanism 4 is installed at the upper end of the support 3, and the driving end of the driving mechanism 4 is located inside the support 3. A movable frame 5 is slidably connected to the inner wall of the support 3. The movable frame 5 is threadedly connected to the driving end of the driving mechanism 4. A cylinder 6 is fixedly connected to the lower surface of the movable frame 5. A cutting blade 7 is installed at the driving end of the cylinder 6. A clamping assembly 8 is provided at the connection between the support 3 and the base 1.

[0026] In this embodiment: the clamping assembly 8 includes a guide rail 81, the guide rail 81 is fixedly connected to the side surface of the bracket 3, the surface of the guide rail 81 is slidably connected to a slider 82, the surface of the slider 82 is fixedly connected to a connecting plate 83, the front and rear sides of the connecting plate 83 are fixedly connected to clamping plates 84, the lower surface of the connecting plate 83 is fixedly connected to a connecting plate 85, and the surface of the connecting plate 85 is fixedly connected to a protrusion 86.

[0027] The clamping assembly 8 also includes a guide frame 87, which is fixedly connected to the upper inner wall of the base 1. A servo motor 88 is fixedly connected to the left side of the guide frame 87. A bidirectional lead screw 89 is installed at the drive end of the servo motor 88. A connecting frame 810 is slidably connected inside the guide frame 87. A threaded sleeve 811 is fixedly connected to the outside of the connecting frame 810. The threaded sleeve 811 is threadedly connected to the surface of the bidirectional lead screw 89. A linkage frame 812 is fixedly connected to the side of the connecting frame 810 near the connecting plate 85. The linkage frame 812 is slidably connected to the surface of the protrusion 86.

[0028] Specifically, the slider 82 contacts the side surface of the bracket 3, and the connecting plate 83 contacts the side surface of the bracket 3. Through the cooperation of the slider 82 and the guide rail 81, the movement direction of the connecting plate 83 can be guided to ensure that the connecting plate 83 moves in the specified direction and reduce the offset of the connecting plate 83 during the movement.

[0029] Specifically, the clamping plate 84 is L-shaped and contacts the side surface of the base 1.

[0030] In this embodiment: the clamping plate 84 can move downward under the drive of the connecting plate 83, and press the roll material on the base 1 through the protruding part located above the base 1, thereby cooperating with the base 1 to clamp and lock the position of the roll material.

[0031] Specifically, the connecting plate 85 contacts the lower inner wall of the base 1. The connecting plate 85 can connect the protrusion 86 and the connecting plate 83, so that when the protrusion 86 is pushed by the linkage frame 812, the connecting plate 83 can be moved by the protrusion 86.

[0032] In this embodiment, the protrusion 86 is cylindrical.

[0033] In this embodiment: the protrusion 86 can push the connecting plate 85 downward along the slot direction of the linkage frame 812 during the movement of the linkage frame 812, so that the connecting plate 85 can pull the connecting plate 83 downward.

[0034] Specifically, the bidirectional lead screw 89 is rotatably connected to the inner wall of the guide frame 87. Driven by the servo motor 88, the bidirectional lead screw 89 can engage with the threaded sleeves 811 on both sides, thereby driving the connecting frame 810 to move.

[0035] Specifically, the linkage frame 812 is in contact with the side surface of the connecting plate 85, and the slot of the linkage frame 812 is set at an angle.

[0036] In this embodiment: the linkage frame 812 can push the protrusion 86 under the drive of the connecting frame 810, so that the protrusion 86 can pull the connecting plate 85 downward.

[0037] Working principle: When cutting the roll material, place the roll material in the placement rack 2. After placement, pull the free end of the roll material and pass it through the cutting area below the bracket 3. When the roll material is pulled out to a certain length, turn on the power cylinder 6. The power cylinder 6 pushes the cutter 7 downward. The cutter 7 is inserted into the roll material. After the cutter 7 is inserted into the roll material, turn on the power drive mechanism 4. The drive mechanism 4 drives the moving frame 5 through the threaded rod at its drive end. The moving frame 5 drives the cylinder 6 and the cutter 7 to move. During the movement, the cutter 7 cuts the roll material in the cutting area.

[0038] Before cutting, the servo motor 88 is switched on and powered on. The servo motor 88 drives the bidirectional lead screw 89, which pushes the threaded sleeves 811 on both sides outward through the thread. With the cooperation of the connecting frame 810, the threaded sleeves 811 push the linkage frame 812. The linkage frame 812 moves outward and pushes the protrusion 86 through the slot. Guided by the slot, the protrusion 86 pulls down the connecting plate 85. The connecting plate 85 pulls the connecting plate 83. Guided by the guide rail 81 and the slider 82, the connecting plate 83 pulls down the clamping plate 84. During the movement, the clamping plate 84 comes into contact with the surface of the roll material in the cutting area and clamps the roll material with the base 1. After clamping the roll material, the cutting operation can be performed. By setting the clamping component 8, the equipment can clamp the roll material in the processing area during processing, thereby reducing the problem of roll material deviation during cutting, which leads to a decrease in cutting accuracy, and further improving the cutting accuracy of the cutting device and the constraint of the roll material.
