Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tooling, in particular to a novel 90-degree turning machine suitable for small tubes. Background Art

[0002] In the prior art, when transporting small-tube iron pipes, both ends of the small-tube iron pipes are often hung on the sling of a crane, and the crane is used to drive the small-tube iron pipes to move. After the crane moves to the designated position, the small-tube iron pipes are manually turned. Since the weight of the small pipes is between 100 and 300 kilograms, a large force is required to turn the small-tube iron pipes. At the same time, since the small-tube iron pipes have inertia after rotating, it is difficult to stop the rotating small-tube iron pipes manually. Since the length of the small pipes is about 6.2 meters, the small pipes are prone to a large swing amplitude when turning, making it difficult to stably control the small pipes. In this process, there is a risk of the small pipes falling from the slings and injuring people, and the small pipes hitting people when rotating or swinging.

[0003] In order to realize efficient cross-span transportation of ductile iron pipes, ensure uniform rotation of small pipes when turning, and reduce the swing amplitude of small pipes during rotation, a new type of 90° turning machine suitable for small pipes is proposed. Summary of the Invention

[0004] The purpose of the utility model is to provide a pipe turning machine to solve the problems existing in the prior art.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a pipe turning machine, comprising a liftable platform, a reciprocating rotating assembly is provided on the liftable platform, and a roller conveying assembly is provided on the reciprocating rotating assembly;

[0006] The reciprocating rotating assembly includes a sector plate rotatably connected to the liftable platform and a driving member rotatably connected to the liftable platform. The driving member is connected to and drives the sector plate. The roller conveying assembly is arranged on the sector plate.

[0007] In the above technical solution, the lifting platform can lift the material to a certain height, and then use the reciprocating rotating component to drive the material to rotate and turn. After the material is rotated and turned, the lifting platform can drive the material to land on another conveying equipment. The reciprocating rotating component can drive the material to rotate, and the driving part can drive the fan-shaped plate to rotate when the material needs to be turned. The rotation of the fan-shaped plate can drive the roller conveying component to rotate, thereby driving the material to turn.

[0008] Preferably, a rotating shaft is installed on the liftable platform, and the outer periphery of the rotating shaft is rotatably connected to the sector plate.

[0009] In the above technical solution, when the sector plate rotates, the tip portion of the sector plate can rotate around the center of the rotating shaft, and the rotating shaft can be used to support the sector plate and the roller conveying assembly.

[0010] Preferably, the reciprocating rotating assembly further comprises a connecting plate mounted on the driving member, wherein a rotating rod is rotatably connected in the connecting plate, and the rotating rod is rotatably connected to the tip portion of the sector plate.

[0011] In the above technical solution, when it is necessary to drive the material to turn around, the piston rod of the push cylinder extends or contracts, and the piston rod drives the connecting plate and the rotating rod to rotate. The rotating rod rotates relative to the connecting plate while moving, and the rotating rod drives the fan plate to rotate. At the same time, the rotating rod and the fan plate rotate relative to each other.

[0012] Preferably, the reciprocating rotating assembly further comprises an articulated mounting seat mounted on a side of the liftable platform, and the driving member is hinged to the liftable platform via the articulated mounting seat.

[0013] In the above technical solution, the articulated mounting seat can ensure that the driving member is installed on the basis of the liftable platform, so that the driving member can also rotate synchronously when driving the sector plate to rotate.

[0014] Preferably, the roller conveying assembly includes a support base mounted on the fan-shaped plate, a drive motor is mounted on the support base, a plurality of conveying rollers are rotatably connected to the support base, and the drive motor is connected to and drives the plurality of conveying rollers.

[0015] In the above technical solution, the driving motor can drive the coupling to rotate, and the coupling can drive the longitudinal rotation of the motor output shaft to change to lateral rotation, so as to facilitate the installation of the driving motor and the chain in parallel, saving the space of the supporting base. The chain can drive multiple conveying rollers to rotate synchronously, so that the conveying rollers drive the pipe body to move, and then the pipe body can be conveyed from the roller conveying assembly to another conveying equipment.

[0016] Preferably, the liftable platform includes a base plate, a lifting hydraulic cylinder is mounted on the base plate, a placement plate is mounted on the execution end of the lifting hydraulic cylinder, and the reciprocating rotating assembly is mounted on the placement plate.

[0017] In the above technical solution, the lifting hydraulic cylinder can drive the placement plate to move up and down through the extension and retraction of the execution end, so that the placement plate can drive the reciprocating rotating component, the roller conveying component and the material to adjust the height, so that the material is higher than another conveying equipment, so that the material will not be blocked by another conveying equipment when turning around, and it is convenient to transport the material to the conveying equipment after turning around.

[0018] Preferably, the liftable platform further comprises at least one pair of outer support rods hinged on one side of the placement plate and at least one pair of inner support rods hinged on one side of the base plate, the corresponding outer support rods and the inner support rods intersect in the middle and are connected by support rod pins, the outer support rods are slidably connected to the other side corresponding to the base plate, and the inner support rods are slidably connected to the other side corresponding to the placement plate.

[0019] In the above technical solution, the movement of the outer support rod and the inner support rod can support the placement plate when the placement plate is raised or lowered, thereby avoiding the problem that the lifting hydraulic cylinder cannot stably support the placement plate. The support rod pin can limit the outer support rod and the inner support rod, so that the outer support rod and the inner support rod can rotate around the support rod pin.

[0020] Preferably, a limiting plate is installed on the other side of the placement plate and the other side of the base plate, and an angle shaft is installed on the inner support rod and the outer support rod. A limiting hole for the sliding of the angle shaft is opened in the limiting plate, and a screw is threadedly connected on the limiting plate, and the screw can move in the limiting hole.

[0021] In the above technical solution, the angle shaft can limit the upper and lower extreme positions of the placement plate by sliding in the limiting hole of the limiting plate. When the height of the placement plate needs to be fixed, the screw can be rotated to make the screw abut against the angle shaft to prevent the angle shaft from continuing to move, thereby preventing the placement plate from continuing to move downward under the action of gravity. At this time, there is no need to use a lifting hydraulic cylinder to support the placement plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The pipe turning machine installs a reciprocating rotating component on a liftable platform, and can use a driving component to drive a sector plate to rotate. The rotation of the sector plate can drive a roller conveying component to rotate, and the roller conveying component can drive the pipe to turn. Compared with manually driving the pipe to turn, the reciprocating rotating component can ensure that the pipe rotates more smoothly, increases the controllability of the pipe movement, and can prevent the pipe from falling off the hanger and injuring people during the turning process, while reducing the large swing amplitude of the pipe during the rotation process.

[0024] By installing the roller conveying assembly on the reciprocating rotating assembly, the roller conveying assembly can be used to convey the pipe fittings that have completed the U-turn, so that the pipe fittings that have completed the U-turn can be transported to another conveying device.

[0025] The lifting hydraulic cylinder in the liftable platform can drive the placement plate to move up and down through the extension and retraction of the execution end, so that the placement plate can drive the reciprocating rotating component, the roller conveying component and the pipe fittings to adjust the height, so that the pipe fittings are higher than another conveying equipment, so that the pipe fittings will not be blocked by another conveying equipment when turning around, and at the same time, it is convenient for the pipe fittings to be transported to the conveying equipment by the roller conveying component after turning around.

DETAILED DESCRIPTION

[0036] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please refer to Figures 1 to 9 In this embodiment, a pipe turning machine includes a liftable platform 1, a reciprocating rotating component 200 is provided on the liftable platform 1, and a roller conveying component 300 is provided on the reciprocating rotating component 200; the reciprocating rotating component 200 includes a fan-shaped plate 201 rotatably connected to the liftable platform 1 and a driving member 202 rotatably connected to the liftable platform 1, the driving member 202 is connected to and drives the fan-shaped plate 201, and the roller conveying component 300 is arranged on the fan-shaped plate 201.

[0038] The liftable platform 1 in this embodiment can lift the material 4 to a certain height, and then use the reciprocating rotating component 200 to drive the material 4 to rotate and turn. After the rotation and turning of the material 4 are completed, the liftable platform 1 can drive the material 4 to land on another conveying equipment. The reciprocating rotating component 200 can drive the material 4 to rotate, and the driving member 202 can drive the fan-shaped plate 201 to rotate when the material 4 needs to be turned. The rotation of the fan-shaped plate 201 can drive the roller conveying component 300 to rotate, thereby driving the material 4 to turn.

[0039] It should be noted that this equipment is suitable for the 90° reversing conveying of DN80~300 ductile iron pipes. This equipment can also perform reversing conveying of other materials 4 at specified angles as needed. Since the driving member 202 is used to drive the fan plate 201 to rotate, and the fan plate 201 is used to drive the material 4 to rotate, the material 4 is guaranteed to rotate smoothly, and its rotation speed is also relatively uniform, which can ensure that the material 4 will not be thrown out from the roller conveyor assembly 300 under the action of inertia during the turning process. By arranging the driving member 202 on the side of the placement plate 7, the space above the placement plate 7 can be saved, and the driving member 202 can be avoided from increasing the overall height of the turning machine, so that the turning machine can be better adapted to other equipment.

[0040] As a preferred embodiment, a rotating shaft 203 is installed on the liftable platform 1, and the outer periphery of the rotating shaft 203 is rotatably connected to the sector plate 201. The reciprocating rotating component 200 also includes a connecting plate 204 installed on the driving member 202, and a rotating rod 205 is rotatably connected inside the connecting plate 204. The rotating rod 205 is rotatably connected to the tip part of the sector plate 201. The reciprocating rotating component 200 also includes an articulated mounting seat installed on the side of the liftable platform 1, and the driving member 202 is hinged to the liftable platform 1 through the articulated mounting seat, and the driving member 202 is a push cylinder.

[0041] The articulated mounting seat in this embodiment includes a mounting plate 206 mounted on the side of the liftable platform 1 and two rotating rods 208 mounted on the driving member 202. Two ear plates 207 are installed on the mounting plate 206. The two ear plates 207 rotate in the corresponding ear plates 207 respectively. A baffle 209 is installed on the end of the rotating rod 208 away from the driving member 202. The articulated mounting seat can ensure that the driving member 202 is installed on the basis of the liftable platform 1, so that the driving member 202 can also rotate synchronously when driving the fan-shaped plate 201 to rotate.

[0042] It should be noted that when it is necessary to drive the material 4 to turn around, the piston rod of the pushing cylinder is extended or contracted, and the piston rod drives the connecting plate 204 and the rotating rod 205 to rotate. The rotating rod 205 rotates relative to the connecting plate 204 while moving, and the rotating rod 205 drives the fan plate 201 to rotate. At the same time, the rotating rod 205 and the fan plate 201 rotate relative to each other. When the driving member 202 drives the fan plate 201 to rotate, the driving member 202 will swing around the position of the rotating rod 208 as the center, so that the tip part of the fan plate 201 can rotate around the center of the rotating shaft 203. The rotating rod 208 can be limited by rotating the rotating rod 208 in the ear plate 207, so that the rotating rod 208 and the driving member 202 rotate in the same plane. The baffle 209 can prevent the rotating rod 208 from falling from the ear plate 207 in an accident.

[0044] The drive motor 302 in this embodiment can drive the coupling 304 to rotate, and the coupling 304 can drive the longitudinal rotation of the output shaft of the motor 302 to change to lateral rotation, so as to facilitate the installation of the drive motor 302 in parallel with the chain, saving space for the support base 301, and the chain can drive multiple conveying rollers 303 to rotate synchronously, so that the conveying rollers 303 drive the material 4 to move, and then the material 4 can be conveyed from the roller conveying assembly 300 to another conveying equipment.

The liftable platform 1 also includes at least one pair of outer support rods 8 hinged on one side of the placement plate 7 and at least one pair of inner support rods 9 hinged on one side of the base plate 5. The corresponding outer support rods 8 and inner support rods 9 cross in the middle and are connected by a support rod pin 10. The outer support rod 8 is slidably connected to the other side corresponding to the base plate 5, and the inner support rod 9 is slidably connected to the other side corresponding to the placement plate 7.

[0046] The lifting hydraulic cylinder 6 in this embodiment can drive the placement plate 7 to move up and down by telescoping the execution end, so that the placement plate 7 can drive the reciprocating rotating component 200, the roller conveying component 300 and the material 4 to adjust the height, so that the material 4 is higher than the other conveying equipment, so that the material 4 will not be blocked by the other conveying equipment when turning around, and at the same time it is convenient for the material 4 to be transported to the conveying equipment after turning around. The movement of the outer support rod 8 and the inner support rod 9 can support the placement plate 7 when it is raised and lowered, thereby avoiding the problem that the lifting hydraulic cylinder 6 cannot stably support the placement plate 7. The support rod pin 10 can limit the outer support rod 8 and the inner support rod 9, so that the outer support rod 8 and the inner support rod 9 rotate around the support rod pin 10.

[0048] In this embodiment, the angle shaft 13 can limit the upper and lower extreme positions of the placement plate 7 by sliding in the limiting hole 12 of the limiting plate 11. When the height of the placement plate 7 needs to be fixed, the screw 14 can be rotated to make the screw 14 abut against the angle shaft 13 to prevent the angle shaft 13 from continuing to move, thereby preventing the placement plate 7 from continuing to move downward under the action of gravity.
