Description

Technical Field

[0001] The utility model relates to the technical field of high-speed railway bridge seam cutting machines, in particular to a seam cutting machine for high-speed railway bridge construction. Background Art

[0002] A high-speed railway bridge is a structure built for railways to cross rivers, lakes, straits, valleys or other obstacles, and for the purpose of achieving a three-dimensional intersection between railway lines and railway lines or roads. It is the abbreviation of high-speed railway bridge engineering, a branch of railway engineering. Therefore, it also includes a series of technologies for the construction and maintenance of high-speed railway bridges. High-speed railway bridges are divided into railway bridges and dual-purpose highway and railway bridges according to their uses; and are divided into beam bridges, arch bridges, rigid frame bridges, suspension bridges, cable-stayed bridges and combined system bridges, etc. according to their structures. During use, the teeth of the rotating slitting knife directly contact the cutting debris, causing some of the cutting debris to be stuck in the teeth of the slitting knife. The slitting knife will greatly reduce the cutting rate after being stuck with the debris. For this reason, a slitting machine for high-speed railway bridge construction is proposed.

[0003] In order to solve the above problems, after searching, the prior art discloses (application number: CN202320463608.2) a seam cutting machine for high-speed railway bridge construction; the article proposes "including a seam cutting machine main body frame, two movable rollers rotatably installed at the bottom end of the seam cutting machine main body frame and a hand-push handle fixedly installed at the top end of the seam cutting machine main body frame, characterized in that: a water tank is installed on the upper surface of the seam cutting machine main body frame, a pair of positioning belts are provided above the water tank, both ends of the two positioning belts are fixedly connected to the seam cutting machine main body frame, and a high-pressure water pump is fixedly installed at the bottom end of the water tank. The utility model overcomes the shortcomings of the existing technology. The high-pressure water transported through the water supply pipe can enter the interior of the rotating cylinder along the connecting bend pipe. When the starting motor drives the cutting disc to rotate, the rotating cutting disc can drive the transmission wheel in contact with it to rotate, and the rotating rotating cylinder cooperates with the high-pressure water sprayed from the water outlet to impact the tooth notch at the edge of the cutting disc;".

[0050] As a preferred embodiment, the protective cover 306 is semicircular in shape and covers the upper half of the cutting blade 305;

[0051] Example 2:

[0052] On the basis of Example 1, in order to further increase the depth of the ground cut of the high-speed railway bridge, a lifting mechanism is provided on the bottom plate 1;

[0064] Example 4:

[0065] On the basis of Example 3, in order to further improve the efficiency of ground slit cutting of high-speed railway bridges, a cooling component is provided on the bottom plate 1;

[0066] As a preferred embodiment, the cooling component includes a water tank 501 arranged on the bottom plate 1 for storing water;

[0067] As a preferred embodiment, the cooling assembly further includes: a water inlet 502, arranged at the upper end of the water tank 501, for replenishing water into the water tank 501; a water pump 503, fixedly arranged on a side of the upper end of the water tank 501 away from the water inlet 502; a telescopic hose 504, one end of which is fixedly connected to the water pump 503 and the other end of which is fixedly connected directly above the protective cover 306, for telescoping and stretching according to the up and down movement of the protective cover 306, and continuously transporting water from the water tank 501 through the telescopic hose 504 to the protective cover 306 through the water pump 503 to cool the cutting blade 305;

[0068] It should be noted that the telescopic hose 504 is made of rubber, which has good elasticity and can be freely expanded and contracted within a certain range, so that it can easily cope with changes in water pressure while maintaining the stability and durability of the hose body.

[0069] Working principle: When in use, first drive the device to the desired place through the wheel at the bottom of the base plate 1, then turn on the motor 301, the motor 301 drives the pulley 1 302 to rotate, the pulley 1 302 drives the belt 1 303 to rotate, the belt 1 303 drives the pulley 2 304 to rotate, the pulley 2 304 drives the cutting blade 305 to rotate on the fixed frame 203, and then screw the screw rod 202 to rotate on the fixed frame 203, the screw rod 202 is connected to the bracket 201 through a thread The fixing frame 203 is driven to slide downward on the bracket 201, and the protective cover 306 drives the telescopic hose 504 to pull, and the cutting blade 305 is completed when the bottom of the cutting blade is in contact with the ground. As the screw rod 202 is continuously turned, the cutting blade 305 continues to cut the ground downward, and the roller 404 is in contact with the ground and drives the slide rod 403 to slide on the sleeve 401 while compressing the spring 405. At this time, the pointer 407 on the slide rod 403 slides upward synchronously. When the cutting depth corresponds to the scale line 406 on the sleeve 401, stop twisting the screw rod 202, and then push the handle on the base plate 1. The four sets of wheels at the bottom of the base plate 1 drive the cutting blade 305 to move forward at a constant speed to cut the ground. At the same time, the roller 404 rotates on the slide bar 403 following the movement of the base plate 1. By equipping the scale line 406 and twisting the screw rod 202 to accurately adjust the cutting depth of the cutting blade 305, it can be ensured that each cutting reaches the preset depth requirement. This helps to reduce errors and improve the overall construction quality and accuracy. At the same time, the water pump 503 is turned on. The water pump 503 transports water from the water tank 501 to the telescopic hose 504, and then transports it from the telescopic hose 504 to the protective cover 306. It is sprayed on the cutting blade 305 through the protective cover 306. This not only cools the cutting blade 305 during cutting, but also prevents dust generated during cutting from polluting the outside world. A water inlet 502 is provided on the water tank 501 for replenishing water into the water tank 501.

[0070] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
