Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bridge construction technology, and specifically relates to a cutting device for bridge construction. Background Technology
[0002] Roads and bridges generally consist of several major parts, including the roadbed, the pavement, and the bridge itself. The roadbed is a linear structure built of earth or stone, which bears the weight of its own soil and rock, the weight of the pavement, and the traffic load transmitted from the pavement. It is an important part of the entire highway structure. During the construction of roads and bridges, it is necessary to repair and cut the pavement, which requires the use of a cutting machine to cut and groove the joints.
[0003] Chinese patent CN202420019989.X discloses a bridge construction joint cutting device, including a base plate and a joint cutting mechanism. The joint cutting mechanism includes a joint cutting machine, a lifting plate, four rollers, two sets of connecting components, a moving component, two sets of support components, two sets of auxiliary components, and a pushing component. Each set of connecting components includes a hinge block, a support rod, and a moving block. The four rollers are fixedly connected to the lower surface of the base plate. The lifting plate is set on the upper surface of the base plate. The joint cutting machine is fixedly connected to one side of the lifting plate. The two sets of connecting components are symmetrically arranged on the bottom surface of the lifting plate. The hinge block is fixedly connected to the base plate. One end of the support rod is hinged to the hinge block, and the other end of the support rod is hinged to the moving block. The moving component is set on the upper surface of the base plate. The two sets of support components are symmetrically arranged on both sides of the lifting plate.
[0004] Current bridge construction work requires the use of cutting equipment to cut joints in bridges. However, the cutting process easily generates a lot of dust. The dust that floats in the air not only has a certain impact on the environment, but is also easily inhaled by workers. Over time, this will cause irreversible damage to the health of the workers.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in the related technologies, this utility model proposes a cutting device for bridge construction to overcome the above-mentioned technical problems existing in the existing related technologies.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to a cutting device for bridge construction, comprising a movable frame, a support frame connected to the top of the movable frame, and a reinforcing plate connected to the top of the support frame.
[0009] One end of the reinforcing plate is connected to a second drive source. A slit-cutting assembly is provided above the movable frame. A dust collection box is connected to the top of the movable frame. A dust cleaning assembly is provided on the dust collection box. A cover is snapped onto one side of the dust collection box. A third drive source is connected to the top of the movable frame. A suction pipe is connected to the input end of the third drive source. A dust outlet pipe is connected to the output end of the third drive source. One end of the dust outlet pipe is connected to one side of the dust collection box.
[0010] The surface of the slit assembly is poweredly connected to the power output end of the second drive source, so as to drive the slit assembly to move up and down in the vertical direction to slit the bridge through the second drive source;
[0011] The surface of the dust removal component is slidably connected to the interior of the other side of the dust collection box, so as to move horizontally to push out the dust drawn into the dust collection box by the third drive source.
[0012] Furthermore, the slit assembly includes a fixing frame, a first drive source, and a support plate. The fixing frame is disposed on the power output end of the second drive source, and a protective cover is connected to the surface of the fixing frame. The first drive source is disposed inside the fixing frame, and a slit blade is poweredly connected to the power output end of the first drive source. The support plate is disposed on the surface of the fixing frame, and a limit plate is connected to one side of the support plate.
[0013] Furthermore, the surface of the first drive source is connected to one side of the protective cover, and the power output end of the first drive source passes through the middle of the protective cover.
[0014] Furthermore, both the support plate and the limiting plate are slidably connected to the inner side of the support frame.
[0015] Furthermore, the dust removal assembly includes two sliding rods, two contraction springs, a sliding groove, and a slider. Both sliding rods are slidably connected to the interior of the other side of the dust collection box. One end of each sliding rod is connected to a dust-pushing plate, the surface of which slides against the inner wall of the dust collection box. The two contraction springs are respectively sleeved on the outer sides of the two sliding rods. The sliding groove is formed on the inner side of the top of the dust collection box. The slider is located at the top of the dust-pushing plate. The other end of each sliding rod is connected to a handrail.
[0016] Furthermore, the two ends of the two retraction springs are respectively connected to one side of the dust pusher plate and the inner wall of the other side of the dust collection box.
[0017] Furthermore, the slider is slidably connected to the groove.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model uses a first driving source to easily drive the cutting blade to rotate and cut the bridge, a second driving source to easily adjust the cutting depth of the cutting blade, and a third driving source to easily draw dust into the dust collection box, thus avoiding the workers from inhaling too much dust and causing harm to their bodies, and also helps to protect the environment.
[0020] 2. By pushing the dust pusher to the right, dust can be easily discharged through the inside of the dust collection box, making it convenient to vacuum and clean up dust at the same time. At the same time, the contraction of the spring allows the dust pusher to move to the left and reset when it is not necessary to clean the dust inside the dust collection box. This leaves more space for the third drive source to suck the dust into the dust collection box later. In addition, as the dust pusher moves, the slider will slide accordingly inside the slide groove, preventing the edge of the dust pusher from being completely in contact with the inside of the dust collection box, which helps to improve the smoothness of the dust pusher's movement.
[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0033] Please see Figures 1-6 As shown, this utility model is a cutting device for bridge construction, including a movable frame 1, a support frame 4 connected to the top of the movable frame 1, and a reinforcing plate 5 connected to the top of the support frame 4.
[0034] One end of the reinforcing plate 5 is connected to a second drive source 6. A slit-cutting assembly 2 is provided above the movable frame 1. A dust collection box 8 is connected to the top of the movable frame 1. A dust cleaning assembly 3 is provided on the dust collection box 8. A cover 7 is snapped onto one side of the dust collection box 8. A third drive source 9 is connected to the top of the movable frame 1. A suction pipe 10 is connected to the input end of the third drive source 9. A dust outlet pipe 11 is connected to the output end of the third drive source 9. One end of the dust outlet pipe 11 is connected to one side of the dust collection box 8.
[0035] The surface of the cutting assembly 2 is poweredly connected to the power output end of the second drive source 6, so as to drive the cutting assembly 2 to move up and down in the vertical direction to cut the bridge through the second drive source 6;
[0036] The surface of the dust removal component 3 is slidably connected to the interior of the other side of the dust collection box 8, so as to move horizontally to push out the dust drawn into the dust collection box 8 by the third drive source 9.
[0037] First, the mobile frame 1 is moved to the desired cutting position. Then, the cutting assembly 2 is driven down by the second drive source 6 to cut the bridge. During the cutting process, a lot of dust is inevitably generated. Therefore, the third drive source 9 is driven to operate, and the generated dust is drawn into the dust collection box 8 through the suction pipe 10 and the dust outlet pipe 11. This prevents workers from inhaling too much dust and causing harm to their bodies, and also helps to protect the environment. After the cutting is completed, when it is necessary to clean the concentrated dust inside the dust collection box 8, the cover 7 is opened and the dust removal assembly 3 is manually pushed to the right to remove the dust from the inside of the dust collection box 8. This makes it convenient to both vacuum and clean the dust, and the operation is simple.
[0038] The second drive source 6 allows for flexible adjustment of the cutting depth of the cutting assembly 2, improving the flexibility of use. The third drive source 9 facilitates the extraction of dust into the dust collection box 8, preventing workers from inhaling too much dust and causing harm to their bodies, and also helps protect the environment. Pushing the dust removal assembly 3 to the right facilitates the removal of dust through the dust collection box 8, making it convenient to both vacuum and clean up dust.
[0039] In one embodiment, the slit assembly 2 includes a fixing frame 21, a first drive source 23, and a support plate 25. The fixing frame 21 is disposed on the power output end of the second drive source 6, and a protective cover 22 is connected to the surface of the fixing frame 21. The first drive source 23 is disposed inside the fixing frame 21, and a slit blade 24 is poweredly connected to the power output end of the first drive source 23. The support plate 25 is disposed on the surface of the fixing frame 21, and a limit plate 26 is connected to one side of the support plate 25.
[0040] First, the movable frame 1 is moved to the desired cutting position. Then, the second drive source 6 drives the fixed frame 21, protective cover 22, first drive source 23, cutting blade 24, and support plate 25 to move downwards as a whole. Next, the first drive source 23 is driven to rotate the cutting blade 24 to cut the bridge. The cutting depth of the cutting blade 24 can be adjusted by the second drive source 6, improving the flexibility of use. When the cutting blade 24 is raised or lowered, the support plate 25 and the limiting plate 26 slide synchronously inside the support frame 4 to support the cutting blade 24 as a whole. To improve the lifting and lowering stability of the cutting blade 24 and the cutting process, a lot of dust or powder is inevitably generated during the cutting process. Therefore, the third drive source 9 is driven to operate, and the generated dust is drawn into the dust collection box 8 through the suction pipe 10 and the dust outlet pipe 11. This avoids the operator from inhaling too much dust and causing harm to the body, and also helps to protect the environment. After the cutting is completed, the concentrated dust inside the dust collection box 8 needs to be cleaned. Open the cover 7 and manually push the dust removal component 3 to the right to remove the dust from the inside of the dust collection box 8. This makes it convenient to both vacuum and clean the dust, and the operation is simple.
[0041] The first drive source 23 facilitates the rotation of the cutting blade 24 to cut the bridge, the second drive source 6 facilitates the flexible adjustment of the cutting depth of the cutting blade 24, and the third drive source 9 facilitates the extraction of dust into the dust collection box 8, preventing workers from inhaling too much dust and causing harm to their bodies, and also helps to protect the environment. By pushing the dust removal component 3 to the right, the dust can be easily removed through the dust collection box 8, making it convenient to both vacuum and clean the dust.
[0042] In one embodiment, for the first drive source 23, the surface of the first drive source 23 is connected to one side of the protective cover 22, and the power output end of the first drive source 23 passes through the middle of the protective cover 22, thereby facilitating the improvement of the stability of the first drive source 23 and the cutting blade 24 during cutting.
[0043] In one embodiment, for the support plate 25, both the support plate 25 and the limiting plate 26 are slidably connected to the inner side of the support frame 4, so as to facilitate the movement inside the support frame 4 as the cutting blade 24 rises and falls, which further improves the stability of the cutting.
[0044] In one embodiment, the dust removal assembly 3 includes two sliding rods 31, two contraction springs 33, a sliding groove 34, and a slider 35. Both sliding rods 31 are slidably connected to the interior of the dust collection box 8 on the other side. One end of each sliding rod 31 is connected to a dust-pushing plate 32, the surface of which slides against the inner wall of the dust collection box 8. The two contraction springs 33 are respectively sleeved on the outer sides of the two sliding rods 31. The sliding groove 34 is formed on the inner side of the top of the dust collection box 8. The slider 35 is located at the top of the dust-pushing plate 32. The other end of each sliding rod 31 is connected to a handrail 36, facilitating manual removal of dust from the interior of the dust collection box 8 without the need for electricity, thus saving resources.
[0045] In one embodiment, for the above-mentioned retraction springs 33, the two ends of the two retraction springs 33 are respectively connected to one side of the dust pusher plate 32 and the inner wall of the other side of the dust collection box 8, thereby facilitating the provision of retraction and reset force for the dust pusher plate 32, which helps to reserve enough space inside the dust collection box 8 for subsequent dust collection when there is no need to clean the dust inside the dust collection box 8.
[0046] In one embodiment, the slider 35 is slidably connected to the groove 34, thereby facilitating the improvement of the stability of the pusher plate 32 when it moves.
[0047] In summary, using the above-mentioned technical solution of this utility model, the movable frame 1 is first moved to the desired cutting position. Then, the second drive source 6 drives the fixed frame 21, protective cover 22, first drive source 23, cutting blade 24, and support plate 25 to move downwards as a whole. Next, the first drive source 23 is driven to rotate the cutting blade 24 to cut the bridge. The cutting depth of the cutting blade 24 can be adjusted by the second drive source 6, improving the flexibility of use. When the cutting blade 24 is raised or lowered, the support plate 25 and the limiting plate 26 slide synchronously inside the support frame 4 to support the cutting blade 24 as a whole, improving the stability of the cutting blade 24 during raising, lowering, and cutting. During the cutting process, a lot of dust or powder is inevitably generated. Therefore, the third drive source 9 is driven to operate, and the generated dust is drawn into the dust collection box 8 through the suction pipe 10 and the dust outlet pipe 11 to avoid dust accumulation. Inhaling excessive dust can harm the health of workers and help protect the environment. After cutting, when cleaning the concentrated dust inside the dust collection box 8, open the cover 7 and hold the handle 36 to push the slide bar 31 and the dust pusher 32 to the right. The dust pusher 32 will push the dust accumulated in the right half of the dust collection box 8 outward. While the dust pusher 32 moves, the slider 35 will move inside the slide groove 34 to prevent the side of the dust pusher 32 from completely touching the inside of the dust collection box 8, thus improving the smoothness of the movement of the dust pusher 32. After the dust is cleared out of the dust collection box 8, close the cover 7. When the handle 36 loses its force, the contraction of the compression spring 33 will drive the slide bar 31 and the dust pusher 32 to the left to reset, leaving more space for the third drive source 9 to suck the dust into the dust collection box 8. This makes it convenient to vacuum and clean the dust at the same time, and the operation is simple.
[0048] Through the above technical solution, 1. The first drive source 23 facilitates the rotation of the cutting blade 24 to cut the bridge, the second drive source 6 facilitates the flexible adjustment of the cutting depth of the cutting blade 24, and the third drive source 9 facilitates the extraction of dust into the dust collection box 8, avoiding the harm to the workers caused by inhaling too much dust and helping to protect the environment; 2. Pushing the dust pusher 32 to the right facilitates the removal of dust through the interior of the dust collection box 8, making it convenient to both vacuum and clean the dust. At the same time, the contraction of the spring 33 facilitates the leftward movement of the dust pusher 32 to reset when it is not necessary to clean the dust inside the dust collection box 8, reserving a large space for the third drive source 9 to subsequently vacuum the dust into the interior of the dust collection box 8. Furthermore, as the dust pusher 32 moves, the slider 35 will slide accordingly inside the slide groove 34, preventing the sides of the dust pusher 32 from being completely in contact with the interior of the dust collection box 8, which helps to improve the smoothness of the movement of the dust pusher 32.
