Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a vertical cutting device for road and bridge construction. Background Art

[0002] Road bridges are generally composed of several parts, such as roadbed, pavement, bridge, tunnel engineering and traffic engineering facilities. Plate bridges are the most common bridge types in highway bridges with large volume and wide coverage. They have simple structure and clear force. They can adopt reinforced concrete and prestressed concrete structures. They can be made into solid and hollow ones, and cast in situ to adapt to various shapes of curved, sloped and inclined bridges. Therefore, they are widely used in general highways, high-grade highways and urban road bridges, especially medium and small span bridges on highways in plain areas with limited building height, which are particularly popular, thereby reducing the height of embankment fill, occupying less arable land and saving earthwork. Road bridges are composed of roadbed, pavement, bridge, tunnel engineering, etc., focusing on linear design to maintain its continuity. During the construction of road bridges, materials need to be cut.

[0003] Among them, the patent with publication number: CN216831622U discloses a vertical cutting device for road and bridge construction, including a guide slide rail, a liftable cutting mechanism is fixedly installed inside the guide slide rail, one end of the guide slide rail is rotatably connected to a plurality of cutting support plates, a fixing component is fixedly installed in the middle of the cutting support plate, and a cutting positioning component is fixedly installed at one end of the cutting support plate.

[0004] When the structure is in use, the fixing component is controlled to fix and separate the cutting support plate and the guide rail, and the cut material is fixed by the cutting positioning component. Multiple cutting support plates are provided to enable continuous cutting of multiple materials. However, when the structure is in use, it is not easy to gather different materials (such as beams and supporting components required for bridges) together and then cut them one by one. The cutting process takes a certain amount of time, which results in low cutting efficiency of the device and slow construction progress. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vertical cutting device for road and bridge construction, aiming to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a vertical cutting device for road and bridge construction, comprising a base, on which a conveying and cutting assembly is arranged.

[0007] The conveying and cutting assembly includes a turntable arranged at the bottom of the base, a plurality of measuring cylinders with adjustable positions are arranged on the top of the turntable, and the measuring cylinders are rotatably connected to the turntable, a lower hopper is installed at the bottom of the base by bolts, a protective shell is arranged in the dislocation cavity, a supporting block is arranged on one side of the protective shell, the supporting block and the protective shell are both installed on the base, and the supporting block is located at the bottom of the center rod and is rotatably connected to the center rod, and a slag discharge port for slag discharge is arranged on the outer side of the protective shell.

[0008] It can be seen that in the above technical solution, the material falls into the measuring cylinder without contacting the supporting member, so that the function of automatically measuring the size of the material during cutting is realized, ensuring that each material can be cut into the same size and the cutting accuracy is ensured. After the cutting is completed, the measuring cylinder is driven to rotate by the turntable, so that the cut material can be discharged through the guide of the lower hopper.

[0009] A center rod is provided at the top of the base, and a plurality of separation cylinders for guiding materials are distributed on the outside of the center rod, and an offset cavity is formed between the center rod and the base. The top of the inner cavity of the protective shell is rotatably connected to an electric push rod through an axle pin, and the output end of the electric push rod is rotatably connected to a lever through an axle pin, one end of the lever is rotatably connected to the protective shell through an axle pin, and one end of the lever extends into the offset cavity, a cutting disk for cutting the workpiece is provided in the protective shell, and a servo motor for driving the pulley group, the turntable and the cutting disk to rotate respectively is provided at the bottom of the pulley group, the turntable and the protective shell, a pulley group is provided on the outside of the separation cylinder, and the pulley group is installed on the base, and a transmission belt is provided at the output end of the pulley group, and the transmission belt is sleeved on the outside of the separation cylinder and is transmission-connected to the separation cylinder, the cross-sectional shape of one end of the lever located in the offset cavity is set to an arc, and a plurality of mocha teeth are provided at the end of the lever.

[0010] It can be seen that in the above technical scheme, when the material is cut by the cutting disc, the electric push rod is used to start the driving lever to rotate along the axis point of the connection between the lever and the protective shell, so that the lever and the mocha teeth can be deflected, so that the mocha teeth extend to the outside of the material, and the material is rotated in the separation cylinder by the deflection of the mocha teeth. In combination with the rotation of the cutting disc along the axis pin point of the separation cylinder, the material can be fully in contact with the cutting disc during cutting, so as to realize the functions of material rotation, pushing and cutting at the same time, thereby improving the cutting efficiency. At the same time, the transmission belt is driven to rotate through the pulley group. When the transmission belt rotates, it drives each separation cylinder to rotate and displace along the axis point of the center rod, so that each material does not contact the support block one by one, so that the material in the corresponding separation cylinder can fall into the measuring cylinder, and at the same time, the cutting disc is rotated to cut the material. During the cutting process, the separation cylinder is continuously driven to rotate by the transmission belt, and the turntable drives each measuring cylinder to rotate, so that the material can approach the cutting disc, and then the cutting disc rotates to pressurize the material when it is cut, thereby effectively improving the material cutting efficiency.

[0011] A hollow disk is provided in each of the plurality of separation cylinders, and two sliding rods are provided on the top of each of the hollow disks, and the sliding rods are arranged opposite to each other, and a clamping plate is slidably connected to the sliding rod, and a clamping wheel for conveying materials is rotatably connected to the clamping plate. Two driving motors are provided on the hollow disk, and an axle pin is installed at the output end of each driving motor through bolts, and a battery for power supply is provided on one side of the driving motor, and both ends of the two axle pins are rotatably connected to a pull rod through an axle pin, and one end of each pull rod extends to one end of the corresponding clamping plate and is rotatably connected to the clamping plate through an axle pin. Two side abutment plates are provided on the outer side of the hollow disk, and each of the side abutment plates is installed on the inner wall of the separation cylinder and is detachably connected to the separation cylinder through bolts, and concave frames are installed at both ends of the two side abutment plates through bolts, and each of the concave frames is rotatably connected to a supporting wheel, and a slip ring is provided on the outer side of the hollow disk, and the outer side of the slip ring extends to the outer side of the supporting wheel and contacts with the supporting wheel.

[0012] It can be seen that in the above technical solution, when the material is transported into the separation cylinder, the outer sides of the material can contact the clamping wheels respectively, and the clamping wheels are limited by the material and drive the clamping plates to slide on the hollow disk, and then the driving motor starts the drive shaft pin to rotate. When the shaft pin rotates, the pull rod will be deflected and the two clamping plates will be close to each other, so that the clamping wheels can be stuck on the outer side of the material, which not only realizes the function of clamping and positioning the material, but also facilitates the friction between the material and the clamping wheels. Through the guidance of the clamping wheels, the bottom of the material can extend into the measuring cylinder, ensuring the stability of the material during cutting. When the lever is deflected and the material is rotated, the material is clamped by the clamping wheels and the clamping plates, so that the clamping wheels and the clamping plates can drive the hollow disk to rotate in the separation cylinder through the support of the slip ring and the support wheel, so that the material rotates more smoothly in the separation cylinder, thereby improving its cutting efficiency.

[0013] The present invention has the following advantages:

[0014] 1. The present invention can place different materials in the separation cylinder respectively, and position the materials through the separation cylinder, and the bottom of the material can extend to the top of the supporting member. At the same time, the transmission belt is driven to rotate through the pulley group. When the transmission belt rotates, it drives each separation cylinder to rotate and move along the axis point of the central rod, so that each material does not contact the supporting member one by one, so that the material in the corresponding separation cylinder can fall into the measuring cylinder for cutting.

[0015] 2. The present invention cuts the material by rotating the cutting disc. During the cutting process, the separation cylinder is continuously driven to rotate by the conveyor belt, and the turntable drives each measuring cylinder to rotate, so that the material can approach the cutting disc. The cutting disc rotates to pressurize the material during cutting, thereby effectively improving the material cutting efficiency.

[0016] 3. The present invention realizes the function of automatically measuring the size of materials when they are cut by allowing the materials to fall into the measuring cylinder without contacting the supporting parts, thereby ensuring that all materials can be cut into the same size and the cutting accuracy. After the cutting is completed, the measuring cylinder is driven to rotate by the turntable, so that the cut materials can be discharged through the guide of the lower hopper, thereby improving the convenience of material cutting.

[0017] 4. The present invention starts the drive motor to drive the shaft pin to rotate. When the shaft pin rotates, the pull rod will be deflected and the two clamping plates will be close to each other, so that the clamping wheel can be clamped on the outside of the material, which not only realizes the function of clamping and positioning the material, but also facilitates the friction between the material and the clamping wheel. Through the guidance of the clamping wheel, the bottom of the material can extend into the measuring cylinder, ensuring the stability of the material during cutting.

[0018] 5. The lever and the mocha teeth of the present invention can be deflected so that the mocha teeth extend to the outside of the material. The material can be driven to rotate in the separation cylinder by the deflection of the mocha teeth. Combined with the rotation of the cutting disc along the axis pin point of the separation cylinder, the material can be fully in contact with the cutting disc during cutting, thereby realizing the functions of rotating, pushing and cutting the material at the same time, thereby improving the cutting efficiency. The hollow disc rotates in the separation cylinder through the support of the support wheel via the slip ring, thereby making the material rotate more smoothly in the separation cylinder, thereby improving its cutting efficiency.

[0019] In summary, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, different materials can be placed in the separation cylinders respectively. Each separation cylinder is rotated and displaced along the axis point of the central rod, so that each material does not contact the support block one by one, so that the material in the corresponding separation cylinder can fall into the measuring cylinder, and the material can approach the cutting disk, and then cooperate with the rotation of the cutting disk to pressurize the material when cutting, effectively improving the material cutting efficiency. By allowing the material to fall into the measuring cylinder without contacting the support block, the material can be automatically measured in size when being cut. The function ensures that each material can be cut into the same size and its cutting accuracy is ensured. The two clamps are close to each other, so that the clamping wheel can be stuck on the outside of the material, which not only realizes the function of clamping and positioning the material, but also facilitates the friction between the material and the clamping wheel. Through the guidance of the clamping wheel, its bottom can extend into the measuring cylinder, and the material is rotated in the separation cylinder by deflecting the friction card teeth. Combined with the rotation of the cutting disc along the axis pin point of the separation cylinder, the material can be fully in contact with the cutting disc during cutting, realizing the functions of rotating, pushing and cutting the material at the same time, thereby improving the cutting efficiency.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] As attached Figure 1-7The vertical cutting device for road and bridge construction shown in the figure can place different materials in the separation cylinder 201 respectively through the conveying and cutting assembly arranged on the base 1 and the corresponding coordinated use of various structures. Each separation cylinder 201 is rotated and displaced along the axis point of the central rod 2, so that each material does not contact the supporting block 105 one by one, so that the material in the corresponding separation cylinder 201 can fall into the measuring cylinder 102, and the material can approach the cutting disk 202, and then cooperate with the rotation of the cutting disk 202 to pressurize the material when cutting, effectively improving the material cutting efficiency, and the material does not contact the supporting block 105 and falls into the measuring cylinder 102, so that the material can be automatically measured in size when it is cut. The function of measuring ensures that each material can be cut into the same size and ensures its cutting accuracy. The two clamps 302 are close to each other, so that the clamping wheel 303 can be stuck on the outside of the material, which not only realizes the function of clamping and positioning the material, but also facilitates the friction between the material and the clamping wheel 303. The bottom of the clamping wheel 303 can extend into the measuring cylinder 102 through the guidance of the clamping wheel 303. The material is rotated in the separation cylinder 201 by deflecting the friction-increasing card teeth 207, and the cutting disk 202 rotates along the axis pin point of the separation cylinder 201, so that the material can be fully in contact with the cutting disk 202 during cutting, realizing the functions of rotating, pushing and cutting the material at the same time, thereby improving the cutting efficiency, and the specific structure of the component is arranged as follows.

[0034] The conveying and cutting assembly includes a turntable 101 arranged at the bottom of the base 1, and a plurality of measuring cylinders 102 with adjustable positions are arranged on the top of the turntable 101, and the measuring cylinders 102 are rotatably connected to the turntable 101. A lower hopper 103 is installed at the bottom of the base 1 by bolts, and a protective shell 104 is arranged in the offset cavity. A supporting member 105 is arranged on one side of the protective shell 104, and the supporting member 105 and the protective shell 104 are both installed on the base 1, and the supporting member 105 is located at the bottom of the center rod 2 and is rotatably connected to the center rod 2, and a slag discharge port 106 for slag discharge is arranged on the outer side of the protective shell 104.

[0035] A center rod 2 is arranged on the top of the base 1, and a plurality of partition cylinders 201 are distributed on the outside of the center rod 2 for guiding the materials. A dislocation cavity is formed between the center rod 2 and the base 1. The top of the inner cavity of the protective shell 104 is rotatably connected to an electric push rod 203 through an axle pin. The output end of the electric push rod 203 is rotatably connected to a lever 204 through an axle pin. One end of the lever 204 is rotatably connected to the protective shell 104 through an axle pin, and one end of the lever 204 extends into the dislocation cavity. A cutting disc 202 for cutting a workpiece is arranged in the protective shell 104, and the pulley group 2 05. The bottom of the turntable 101 and the protective shell 104 are provided with servo motors that respectively drive the pulley group 205, the turntable 101 and the cutting disc 202 to rotate. The outer side of the separation cylinder 201 is provided with a pulley group 205, and the pulley group 205 is installed on the base 1. The output end of the pulley group 205 is provided with a transmission belt 206, which is sleeved on the outer side of the separation cylinder 201 and is connected to the separation cylinder 201 for transmission. The cross-sectional shape of one end of the shifting rod 204 located in the dislocation cavity is set to an arc shape, and a plurality of mocha teeth 207 are provided at the end of the shifting rod 204.

[0036] A hollow disk 3 is provided in each of the plurality of separation cylinders 201, and two slide bars 301 are provided on the top of each hollow disk 3, and each slide bar 301 is arranged opposite to each other, a clamping plate 302 is slidably connected to the slide bar 301, and a clamping wheel 303 for conveying materials is rotatably connected to the clamping plate 302, and two driving motors 304 are provided on the hollow disk 3, and an axle pin is installed at the output end of each driving motor 304 through a bolt, and a battery 305 for power supply is provided on one side of the driving motor, and both ends of the two axle pins 305 are rotatably connected to a pull rod 306 through an axle pin, and One end of each pull rod 306 extends to one end of the corresponding splint 302 and is rotatably connected to the splint 302 through an axle pin. Two side abutment plates 307 are arranged on the outer side of the hollow disk 3, and each side abutment plate 307 is installed on the inner wall of the separation cylinder 201 and is detachably connected to the separation cylinder 201 through bolts. Both ends of the two side abutment plates 307 are installed with concave frames 308 through bolts, and each concave frame 308 is rotatably connected to a supporting wheel 309. A slip ring 310 is sleeved on the outer side of the hollow disk 3, and the outer side of the slip ring 310 extends to the outer side of the supporting wheel 309 and contacts with the supporting wheel 309.

[0037] According to the above structure, when in use, the staff installs the device at the designated position. When cutting the beams or support rods used for road and bridge construction, different materials can be placed in the separation cylinder 201 respectively, and the materials are positioned through the separation cylinder 201, and the bottom of the materials can extend to the top of the supporting block 105. At the same time, the transmission belt 206 is driven to rotate through the pulley group 205. When the transmission belt 206 rotates, it drives each separation cylinder 201 to rotate and move along the axis point of the center rod 2, so that each material does not contact the supporting block 105 one by one, so that the corresponding material in the separation cylinder 201 can fall into the measuring cylinder 102.

[0038] At the same time, the cutting disc 202 rotates to cut the material. During the cutting process, the conveyor belt 206 continuously drives the separation cylinder 201 to rotate, and the turntable 101 drives each measuring cylinder 102 to rotate, so that the material can approach the cutting disc 202. The cutting disc 202 rotates to pressurize the material when cutting, which effectively improves the material cutting efficiency.

[0039] At the same time, by allowing the material to fall into the measuring cylinder 102 without contacting the support member 105, the function of automatically measuring the size of the material during cutting is realized, ensuring that all materials can be cut into the same size and the cutting accuracy is ensured. After the cutting is completed, the measuring cylinder 102 is driven to rotate by the turntable 101, so that the cut material can be discharged through the guide of the lower hopper 103.

[0040] When the material is transported to the separation cylinder 201, the outer side of the material can contact the clamping wheel 303 respectively. The clamping wheel 303 is limited by the material and drives the clamping plate 302 to slide on the hollow disk 3. Then, the driving motor 304 starts the driving shaft pin 305 to rotate. When the shaft pin 305 rotates, the pull rod 306 will be deflected and the two clamping plates 302 will be close to each other, so that the clamping wheel 303 can be stuck on the outer side of the material, which not only realizes the function of clamping and positioning the material, but also facilitates the friction between the material and the clamping wheel 303. Through the guidance of the clamping wheel 303, its bottom can extend into the measuring cylinder 102, ensuring the stability of the material during cutting.

[0041] In addition, when the material passes through the cutting disc 202 and is being cut, the electric push rod 203 is used to start the driving lever 204 to deflect along the axis point of the connection between the lever 204 and the protective shell 104, thereby making the lever 204 and the mocha teeth 207 deflect, so that the mocha teeth 207 extend to the outside of the material, and the mocha teeth 207 rub against the workpiece. The friction force generated by the deflection of the mocha teeth 207 drives the material to rotate in the separation cylinder 201. Combined with the way in which the cutting disc 202 rotates along the axis pin point of the separation cylinder 201, the material can be fully in contact with the cutting disc 202 when being cut, thereby realizing the functions of rotating, pushing and cutting the material at the same time, thereby improving the cutting efficiency.

[0042] And when the lever 204 is deflected to drive the material to rotate, the material is clamped by the clamping wheel 303 and the clamping plate 302, so that the clamping wheel 303 and the clamping plate 302 can drive the hollow disk 3 to rotate in the separation cylinder 201 through the slip ring 310 and the support of the support wheel 309, so that the material can rotate more smoothly in the separation cylinder 201, thereby improving its cutting efficiency.

[0043] Different from the prior art, the present application discloses a vertical cutting device for road and bridge construction. Through the corresponding coordinated use of various structures, different materials can be placed in the separation cylinder 201 respectively. Each separation cylinder 201 is rotated and displaced along the axis of the central rod 2, so that each material does not contact the support block 105 one by one, so that the corresponding material in the separation cylinder 201 can fall into the measuring cylinder 102, and the material can approach the cutting disc 202, and then cooperate with the cutting disc 202 to rotate to pressurize the material when cutting, effectively improving the material cutting efficiency. By making the material fall into the measuring cylinder 102 without contacting the support block 105, the material can be cut automatically when cutting. The function of automatically measuring the size ensures that each material can be cut into the same size and its cutting accuracy is ensured. The two clamping plates 302 are close to each other, so that the clamping wheel 303 can be stuck on the outside of the material, which not only realizes the function of clamping and positioning the material, but also facilitates the friction between the material and the clamping wheel 303. The bottom of the clamping wheel 303 can extend into the measuring cylinder 102 through the guidance of the clamping wheel 303. The material is rotated in the separation cylinder 201 by deflecting the friction-increasing card teeth 207, and the cutting disk 202 rotates along the axis pin point of the separation cylinder 201, so that the material can be fully in contact with the cutting disk 202 during cutting, realizing the functions of rotating, pushing and cutting the material at the same time, thereby improving the cutting efficiency.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
