Description

TECHNICAL FIELD

[0001] The utility model relates to a steel pipe lifting device with material blocking adjustment function. BACKGROUND

[0002] At present, the steel pipe lifting device is a kind of equipment for lifting and conveying steel pipe, and a steel pipe lifting device is disclosed in Chinese patent with announcement number CN203975752U.In the steel pipe lifting device, there is usually a chain and a bracket connected to the chain, and in the conveying process, the first sequentially arranged steel pipe is conveyed to the bracket, then the chain drives the bracket to move in the running process, and the bracket lifts the steel pipe and drives the steel pipe to be lifted upward and conveyed.In some processes, the steel pipe lifting device is needed to lift and convey the steel pipe single by single, and the existing steel pipe lifting device can only lift and convey the steel pipe single by single of specific diameter specifications, and cannot lift and convey the steel pipe single by single of different diameter specifications.For example, when the size of the bracket is designed to be small, the bracket can lift a small-diameter steel pipe each time, so it can lift and convey the small-diameter steel pipe single by single, but when lifting the large-diameter steel pipe, the small size of the bracket causes the steel pipe to fall off the bracket, so it cannot lift and convey the large-diameter steel pipe single by single.For another example, when the size of the bracket is designed to be large, the bracket can lift a large-diameter steel pipe each time, so it can lift and convey the large-diameter steel pipe single by single, but when lifting the small-diameter steel pipe, the large size of the bracket causes the bracket to lift two or more steel pipes at the same time, so it cannot lift and convey the small-diameter steel pipe single by single.It can be seen that the size of the bracket restricts the existing steel pipe lifting device to lift and convey the steel pipe single by single of specific diameter specifications, and cannot lift and convey the steel pipe single by single of different diameter specifications.

[0040] In order to make the content of the utility model more easily be clearly understood, the utility model is further explained in detail below according to specific embodiments and in conjunction with the drawings.

[0042] As Figure 1 , 2 , 4, 5, 6, a kind of steel pipe lifting device with material blocking adjusting function, including feeding mechanism 100, lifting mechanism 200 and material blocking mechanism 300, the material blocking mechanism 300 includes base 1, material blocking block 2 and adjusting drive mechanism;

[0043] The feeding mechanism 100 is loaded with sequentially arranged steel pipe 3, and the feeding mechanism 100 is used to transport steel pipe 3 to move towards the lifting mechanism 200;

[0044] The material blocking block 2 is slidably connected on the base 1, and the material blocking block 2 is used to resist the foremost steel pipe 3 on the feeding mechanism 100 to block the steel pipe 3 on the feeding mechanism 100;

[0045] The adjusting drive mechanism is connected with the material blocking block 2 and is used to drive the material blocking block 2 to move back and forth on the base 1 so as to adjust the position of the material blocking block 2, in turn adjust the position of the steel pipe 3 abutting against the material blocking block 2;

[0046] At least one lifting chain 4 is arranged in the lifting mechanism 200, and the lifting chain 4 is connected with sequentially spaced carriers 5, and the lifting mechanism 200 is used to drive the lifting chain 4 to move in turn, so that the carrier 5 is lifted and transported upwards by the lifting chain 4 to make the carrier 5 hold the foremost steel pipe 3 on the feeding mechanism 100.

[0047] Specifically, the steel pipes 3 arranged in sequence on the feeding mechanism 100 will move towards the lifting mechanism 200, and the steel pipes 3 will stop moving when the frontmost steel pipe 3 on the feeding mechanism 100 abuts against the blocking block 2. Therefore, the blocking block 2 is moved to a suitable position in front of and behind the feeding mechanism 100 by the adjusting driving mechanism according to the diameter of the steel pipe 3 in advance, and the position of the steel pipe 3 abutting against the blocking block 2 can be adjusted by adjusting the position of the blocking block 2, that is, the position where the frontmost steel pipe 3 stops can be adjusted, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100 when the carrier 5 moves with the lifting chain 4, and then the steel pipe 3 is lifted upwards. Specifically, when the diameter of the steel pipe 3 is large, the blocking block 2 is moved to a suitable position away from the feeding mechanism 100 by the adjusting driving mechanism, at this time, the part of the carrier 5 exposed to the blocking block 2 becomes larger, so the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100. Further specifically, when the diameter of the steel pipe 3 is small, the blocking block 2 is moved to a suitable position close to the feeding mechanism 100 by the adjusting driving mechanism, at this time, the part of the carrier 5 exposed to the blocking block 2 becomes smaller, and the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100 and lift it upwards when the carrier 5 moves with the lifting chain 4. Therefore, when lifting steel pipes 3 of different diameters, the position of the steel pipe 3 abutting against the blocking block 2 can be adjusted by adjusting the position of the blocking block 2, that is, the position of the frontmost steel pipe 3 on the feeding mechanism 100 is adjusted, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100, and then the steel pipes 3 of different diameters can be lifted and transported one by one, and the problems of double feeding or dropping can be avoided.

[0056] As shown in Figure 1 , 2 , 4, 5, 6, the lifting mechanism 200 has at least two parallelly arranged lifting chains 4, and the lifting chains 4 are connected with a plurality of sequentially and spacedly arranged carriers 5;

[0063] The drive shaft 21 is connected to each of the drive sprockets 19 respectively;

[0064] The power component is connected to the drive shaft 21 and is used to drive the drive shaft 21 to rotate, thereby driving the drive sprocket 19 to rotate, and thus driving all the lifting chains 4 to move synchronously; specifically, the lifted steel pipe 3 can be guided by the guide rail 22 and rolled into the conveying device 23 to be conveyed to the next process.

[0065] Example 2

Therefore, the position of the blocking block 2 is adjusted in advance according to the diameter of the steel pipe 3 by the adjusting driving mechanism, so that the position of the steel pipe 3 abutting against the blocking block 2 is adjusted, that is, the position of the frontmost steel pipe 3 stopping is adjusted, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100 when the carrier 5 follows the lifting chain 4 to move. Specifically, when the diameter of the steel pipe 3 is large, the blocking block 2 is driven by the adjusting driving mechanism to move to a suitable position away from the feeding mechanism 100, and at this time, the part of the carrier 5 exposed to the blocking block 2 becomes larger, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100. Further specifically, when the diameter of the steel pipe 3 is small, the blocking block 2 is driven by the adjusting driving mechanism to move to a suitable position close to the feeding mechanism 100, and at this time, the part of the carrier 5 exposed to the blocking block 2 becomes smaller, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100 when the carrier 5 follows the lifting chain 4 to move. Therefore, when lifting steel pipes 3 of different diameters, the position of the steel pipe 3 abutting against the blocking block 2 is adjusted by adjusting the position of the blocking block 2, that is, the position of the frontmost steel pipe 3 on the feeding mechanism 100 is adjusted, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100, and then the steel pipes 3 of different diameters can be lifted and conveyed one by one, so that the problems of double feeding or dropping are avoided.

[0084] The transverse moving frame is connected with a tension sprocket 17 abutting against the transverse moving chain 13.

[0085] As shown, Figures 3-6 the lifting mechanism 200 has at least two parallel arranged lifting chains 4 connected with a plurality of sequentially and interval arranged carriers 5.

[0086] The lifting mechanism 200 further comprises a lifting driving mechanism and a mounting assembly corresponding to each of the lifting chains 4.

[0087] The mounting assembly comprises a mounting frame 18, a driving sprocket 19 and a driven sprocket 20.

Further specifically, when the diameter of the steel pipe 3 is small, the material blocking block 2 is driven to move to a suitable position close to the feeding mechanism 100 by the adjusting driving mechanism, at this time, the part of the carrier 5 exposed to the material blocking block 2 becomes smaller, and the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100 and lift it upwards when the carrier 5 moves with the lifting chain 4. Therefore, when lifting steel pipes 3 of different diameters, the stop position of the steel pipe 3 abutting against the material blocking block 2 can be adjusted by adjusting the position of the material blocking block 2, that is, the stop position of the frontmost steel pipe 3 on the feeding mechanism 100 is adjusted, so that the carrier 5 can just lift the frontmost steel pipe 3 on the feeding mechanism 100, and then the steel pipes 3 of different diameters can be lifted and conveyed one by one, and the problems of double feeding or dropping can be avoided.
