Description

Technical Field

[0001] The utility model relates to a novel channel cutting machine, belonging to the technical field of concrete construction equipment. Background Art

[0002] Concrete canals are used for irrigation in agriculture. Using concrete canals for irrigation and water delivery is highly efficient and has low losses. Agricultural concrete canals are generally U-shaped or similar to a U-shaped structure. Because they are made of concrete, expansion joints need to be set to cope with thermal expansion and contraction. An expansion joint needs to be set every few meters.

[0003] The traditional operation method is to manually press and shape the concrete channel using a template cutter as soon as it is formed and before the concrete is solidified. This operation method is inefficient, requires manual implementation, and is labor-intensive. In addition, the construction needs to be carried out when the mixed soil is not solidified. The template cutter often brings out a piece of the mixed soil on the surface of the cut, resulting in pits and unevenness on the inner wall of the channel at the upper edge of the cut.

[0004] At present, although there are some cutting machines for channels, they are not adaptable to U-shaped structures and lack stability in operation. Utility Model Content

[0005] The utility model aims to provide a novel channel seam cutting machine which can cut the expansion joint of a U-shaped water channel, realize mechanized construction work and improve the cutting quality.

[0009] The utility model is further improved as follows: a rotary drive gear is fixedly arranged on the output shaft of the rotary drive motor, and the rotary drive gear meshes with the gear plate for transmission; a linear drive gear is fixedly arranged on the output shaft of the linear drive motor, and the linear drive gear meshes with the linear rack for transmission.

[0010] A further improvement of the utility model is that a linear slide rail is also arranged on the hanging rail, and the rotating seat plate is clamped and matched with the linear slide rail.

[0011] A further improvement of the utility model is that the slitting assembly comprises a saw blade and a slitting motor for driving the saw blade.

[0012] The utility model is further improved as follows: a water spray pipe is arranged corresponding to the saw blade, a water tank is fixedly arranged on the traveling frame, and the water spray pipe is communicated with the water tank.

[0013] A further improvement of the utility model is that the interior of the toothed disc is a rotating support member, and the two are in a sleeve relationship.

[0014] A further improvement of the utility model is that the traveling wheels are traveling rollers.

The cutting device drives the cutting assembly to perform dual movements of rotation and linear movement, or two-dimensional movement, so that expansion joints can be cut at various positions of the inner wall of the concrete of the U-shaped structure channel. The rotation is to adapt to the overall contour of the U-shaped structure, and the linear movement is to make the saw blade adapt to the concrete channel wall at different relative distances, so as to ensure sufficient cutting at various positions.

[0018] In the utility model, the rotation of the cutting device driven by the rotating seat plate is realized by the gear pair between the same toothed disc, and at the same time, the linear movement of the cutting assembly driven by the hanging rail is realized by the gear pair between the same linear gear rail; the transmission by the gear pair can ensure smooth transmission, and the gear transmission ratio is large, the driving force is sufficient, and the operation is smooth.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] The utility model is a new channel seam cutting machine, which is used for cutting expansion joints of concrete water channels, and the cutting construction is performed after the concrete of the concrete water channels is solidified. The concrete water channels are generally U-shaped structures, or structures similar to the U-shaped structures.

[0031] like Figure 1 , Figure 2 As shown, the cutting machine mainly includes a traveling frame 2 and a slitting device. A traveling wheel 1 is arranged at the lower end of the traveling frame 2, and the traveling wheel 1 is driven by a motor to move, thereby driving the traveling frame 2 to move. The slitting device is arranged on the traveling frame 2.

[0032] When the channel seam cutting machine of the utility model is working, the walking wheel 1 walks on the upper edge of the water channel. In order to ensure stable walking, the walking wheel 1 is set as a walking roller. Compared with the wheel structure, the contact area between the walking roller and the upper edge of the water channel is large, and the walking is stable.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the slitting device mainly includes a hanging rail 3, a rotating seat plate 4, a rotating drive motor 5, a linear drive motor 6 and a slitting assembly. The rotating seat plate 4 is installed on the hanging rail 3, and the rotating seat plate 4 is driven by the rotating drive motor 5 to rotate; the rotating seat plate 4 drives the hanging rail 3 to rotate together. The hanging rail 3 and the rotating seat plate 4 can achieve relative position movement, and the hanging rail 3 can move linearly relative to the rotating seat plate 4, and the linear drive motor 6 is correspondingly arranged. The rotating drive motor 5 and the linear drive motor 6 are both fixedly arranged on the rotating seat plate 4.

[0034] A slitting assembly is provided at the lower end of the hanging rail 3, and the slitting assembly is a specific execution assembly for realizing expansion joint cutting. Generally, a saw blade 13 is used and a slitting motor 14 is provided accordingly, and the saw blade 13 is driven to rotate by the slitting motor 14 to realize cutting. A plate is provided at the lower end of the hanging rail 3, and the slitting motor 14 is installed on the plate.

[0035] The slitting device as a whole is in a relative rotational mounting relationship with the traveling frame 2 . Specifically, the slitting device is mounted on the traveling frame 2 using a rotating support 7 .

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a toothed disc 8 is fixedly provided on the walking frame 2, and the rotation drive motor 5 and the toothed disc 8 are driven by a gear pair. Driven by the rotation drive motor 5 and the gear pair, the slitting device as a whole can rotate around the toothed disc 8. A linear rack 9 is provided on the hanging rail 3, and the linear drive motor 6 and the linear rack 9 are driven by a gear pair. Driven by the linear drive motor 6 and the gear pair, the hanging rail 3 can move linearly relative to the rotating seat plate 4. As described above, the overall rotation of the slitting device and the linear movement of the hanging rail 3 can be carried out simultaneously, so that when constructing a concrete canal of a U-shaped structure, a comprehensive expansion joint cutting construction can be achieved on the inner wall of the concrete canal.

[0037] In the specific implementation of the utility model, the output shaft of the rotary drive motor 5 is fixedly provided with a rotary drive gear 10, and the rotary drive gear 10 and the toothed disc 8 form a gear pair for meshing transmission. The output shaft of the linear drive motor 6 is fixedly provided with a linear drive gear 11, and the linear drive gear 11 and the linear rack 9 form a gear pair for meshing transmission. The gear pair transmission is very stable and has sufficient transmission force.

[0038] In the present invention, when working, the hanging rail 3 moves linearly relative to the rotating seat plate 4. With the rotating seat plate 4 as a reference, the hanging rail 3 moves linearly. In order to keep the movement of the hanging rail 3 stable, a linear slide rail 12 is provided on the hanging rail 3, so that the rotating seat plate 4 is snap-fitted with the linear slide rail 12. In this way, the installation and fit between the rotating seat plate 4 and the hanging rail 3 are achieved through snap-fitting. Figure 4 shown.

[0039] The channel cutting machine of the utility model cuts the channel after the concrete is solidified. Therefore, dust will be generated when the saw blade 13 is cutting. In this regard, a water spray pipe 15 can be set accordingly, so that the water outlet of the water spray pipe 15 sprays water toward the saw blade, which plays a role in dust reduction and can also play a role in cooling the saw blade. At this time, it is also necessary to fix a water tank 16 on the traveling frame 2 so that the water spray pipe 15 is connected to the water tank 16. If necessary, a water pump and a valve are set on the water spray pipe 15. The water tank 16 is fixedly installed on the upper end surface of the traveling frame 2.

[0040] In the utility model, the toothed disc 8 cooperates with the rotating drive gear 10, which can be regarded as the rotating drive gear 10 crawling around the outer edge of the toothed disc 8, that is, the entire slitting device can crawl around the outer edge of the toothed disc 8. The cooperation between the toothed disc 8 and the rotating drive gear 10 provides the power for crawling, and the rotating support member 7 provides the rotational support force. Specifically, the interior of the toothed disc 8 is a hollow structure along the axis, and the rotating support member 7 is located in the entire hollow structure, and the toothed disc 8 and the rotating support member 7 are in a fitted relationship. The rotating support member 7 can use a large slewing bearing. The rotating seat plate 4 is fixedly connected to the rotating member of the slewing bearing. Specifically, Figure 4 , Figure 5 As shown, if Figure 4 Assuming that we are looking at the machine from the oblique front, Figure 5 It is viewed from the oblique rear of the machine.

[0041] In the channel slitting machine of the utility model, the rotation of the slitting device and the linear movement of the hanging rail are both performed at a relatively low speed. Therefore, a reducer is connected to the output shaft of the linear drive motor 6, and the linear drive gear 11 is installed on the output shaft of the reducer. A reducer is connected to the output shaft of the rotary drive motor 10, and the rotary drive gear 10 is installed on the output shaft of the reducer, and the speed is reduced by the reducer.

[0042] The driving seam cutting machine of the utility model is also provided with an electric control box, and the electric control box is installed on the traveling frame.

[0043] When the driven slitting machine is used to slit a U-shaped canal, the traveling frame 2 drives the whole machine to the cutting position. The slitting assembly starts from the high end of one side of the canal and gradually moves downward along the contour of the inner wall of the canal. At this time, the rotating seat plate 4 drives the hanging rail 3 and the cutting assembly to rotate under the drive of the rotating drive motor 5. At the same time, the linear drive motor 6 drives the hanging rail 3 to move linearly relative to the rotating seat plate 4, adjusts the horizontal height position of the saw blade 13, and ensures that the saw blade 13 can always fully cut the inner wall of the canal; in this way, sufficient slitting can be achieved at all positions on the inner wall of the canal. Taking the attached figure of the specification as an example, if cutting starts from the right side toward the bottom of the canal, when cutting gradually downward along the contour of the inner wall of the canal, the hanging rail 3 needs to extend downward with the saw blade 13. When cutting from the bottom of the canal along the contour of the inner wall of the canal to the left, the hanging rail 3 needs to be retracted upward with the saw blade 13. After the expansion joint cutting at one position is completed, the traveling wheel drives the whole machine to move to the construction position of the next expansion joint.

[0044] The utility model is a new type of channel seam cutting machine, the cutting component can perform dual motions of rotation and linear movement, and is suitable for cutting expansion joints of U-shaped concrete water channels. The channel seam cutting machine can perform seam cutting construction after the concrete of the water channel is solidified, has a high degree of mechanization, and has high overall construction efficiency.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
