Description

Technical Field

[0001] The invention relates to the technical field of pneumatic diameter system equipment, in particular to a diameter gauge circulation receiving and conveying system of a pneumatic diameter system. Background Art

[0002] For hot-rolled steel pipes used in fields such as oil production, strict diameter detection is generally required to ensure the straightness of the inner diameter of the steel pipe. The existing detection methods mainly include mechanical, pneumatic and other methods. The power of the pneumatic diameter gauge in the steel pipe comes from high-pressure gas. Due to its low energy consumption, simplicity and high efficiency in the diameter process, it has become a diameter process commonly used by steel pipe manufacturers. In the pneumatic diameter process, the diameter gauge is first automatically pushed into the steel pipe by the device at the diameter station, and then passes through the qualified steel pipe at high speed under the action of high-pressure gas. After collision with the receiving buffer device, it rolls into the conveyor roller and is sent back to the diameter station, thus achieving the continuity of the diameter process. In a continuous and fast-paced automated diameter system (more than 6 diameters per minute), it must be ensured that only one diameter gauge is delivered to the diameter platform at a time. When a diameter gauge is blocked during the conveying process or multiple diameter gauges are delivered to the platform at the same time, the entire diameter system will be interrupted or need to be stopped for manual processing, thereby affecting the diameter rhythm and causing the entire production line to be unsmooth.

[0003] In the existing technology related to the conveying of the diameter gauge, for example, patent publication number CN202038689U discloses an automatic lifting device for a steel pipe diameter gauge rod, which solves the technical problem that the operator has to lift the diameter gauge rod to the working position when the steel pipe is calibrated. This technology cannot meet the requirements of fast-paced automatic calibrating.

[0004] For example, publication number CN103991677A discloses a diameter gauge lifting device. The diameter gauge is driven by a driving plate, passes through a horizontal track, a climbing guide, and enters an upper horizontal track. When it runs to the end of the upper horizontal track under the drive of a conveyor chain and a diameter gauge driving plate, it enters a diameter gauge collection table under the guidance of the driving plate for the next diameter adjustment. This patented technology avoids the operator bending over to pick up, reduces labor intensity, and improves diameter adjustment efficiency. However, this technology cannot meet the requirements of fast-paced automatic diameter adjustment. Summary of the invention

[0005] The purpose of the present invention is to provide a circulation receiving and conveying system for a pneumatic diameter system to overcome the technical problems existing in the prior art. To achieve the above technical purpose and the above technical effect, the present invention is implemented through the following technical solutions:

[0006] A diameter gauge circulation receiving and conveying system of a pneumatic diameter gauge system comprises a control cabinet, a lifting platform, a diameter gauge transverse pushing device, a diameter gauge conveying roller, a diameter gauge blocking and releasing device and a diameter gauge receiving trolley, wherein the rear end of the diameter gauge conveying roller is rotatably connected to the roller side plate, the front end of the diameter gauge conveying roller is sleeved with a roller conveying sprocket, the left part of the diameter gauge conveying roller is connected to a second reduction motor through a chain drive, the right part of the diameter gauge conveying roller is connected to a first reduction motor through a chain drive, the first reduction motor and the second reduction motor are fixedly mounted on the roller side plate, and the diameter gauge receiving trolley is connected to a side movable baffle mounting shaft close to the diameter gauge conveying roller.

[0007] Preferably, in the diameter gauge circulating receiving and conveying system of the pneumatic diameter gauge system, the diameter gauge receiving trolley includes a car body, one end of the car body is connected to a buffer bumper, the other end of the car body is connected to a diameter gauge guide tube, the car body is provided with a side movable baffle on the side close to the diameter gauge conveying roller, the side movable baffle is connected to the car body through a side movable baffle mounting shaft, and a top fixed baffle and a top movable baffle are installed on the top of the car body.

[0008] Preferably, in the diameter gauge circulating receiving and conveying system of the pneumatic diameter gauge system, the diameter gauge conveying roller includes a cylindrical conveying roller and a V-shaped conveying roller, the cylindrical conveying roller is close to the lifting platform, and the diameter gauge blocking device is located at the front section of the V-shaped conveying roller close to the cylindrical conveying roller.

[0009] Preferably, in the diameter gauge circulating receiving and conveying system of the pneumatic diameter gauge system, the diameter gauge blocking and releasing device includes a roller baffle frame connected to the roller side plate, a roller baffle cylinder is installed on the roller baffle frame, and the output end of the roller baffle cylinder is connected to the roller baffle.

[0010] Preferably, in the diameter gauge circulation receiving and conveying system of the pneumatic diameter gauge system, the diameter gauge transverse pushing device includes a transverse pushing cylinder, and a transverse pushing bracket is fixedly connected between the transverse pushing cylinder and the roller side plate.

[0012] The beneficial effects of the present invention are:

[0013] The present invention has a reasonable structural design. The center line of the diameter gauge is made parallel to the center line of the diameter gauge conveying roller through the side movable baffle. After the side movable baffle is opened, the diameter gauge falls smoothly onto the diameter gauge conveying roller, thereby preventing the diameter gauge from being stuck between the trolley and the roller. The diameter gauge blocking and releasing device ensures that only one diameter gauge is conveyed to the cylindrical conveying roller segment at a time. The diameter transverse pushing device is used to push the diameter gauge of the cylindrical conveying roller segment to the lifting platform. The lifting platform is used to lift the diameter gauge to a certain height that meets the needs of precise positioning, which serves the subsequent precise positioning and pushing process of the diameter gauge. The present invention can realize the cyclic transportation of the diameter gauge in the diameter process, thereby ensuring high-rhythm diameter efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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.

[0022] See also Figure 1-6As shown, the present embodiment is a diameter gauge circulation receiving and conveying system of a pneumatic diameter gauge system, comprising a control cabinet 1, a lifting platform 2, a diameter transverse pushing device 3, a diameter gauge conveying roller, a diameter gauge blocking and releasing device 6 and a diameter gauge receiving trolley 11, the rear end of the diameter gauge conveying roller is rotatably connected to the roller side plate 12, the front end of the diameter gauge conveying roller is sleeved with a roller conveying sprocket 8, the left part of the diameter gauge conveying roller is connected to the second reduction motor 7 through a chain drive, and the right part of the diameter gauge conveying roller is connected to the first reduction motor 10 through a chain drive, the first reduction motor 10 and the second reduction motor 7 are fixedly mounted on the roller side plate 12, the diameter gauge receiving trolley 11 is connected to a side movable baffle mounting shaft 9 close to the diameter gauge conveying roller, the side movable baffle mounting shaft 9 is driven by a cylinder, the control cabinet 1 controls the operation of the electrical components, and the diameter gauge realizes reciprocating circulation conveying during the operation of the system, which can meet the pneumatic diameter production requirements of steel pipes with a diameter efficiency of more than six steel pipes.

[0023] The diameter gauge receiving trolley 11 includes a car body 111, one end of the car body 111 is connected to a buffer bumper 112, and the other end of the car body 111 is connected to a diameter gauge guide tube 116. The function of the diameter gauge guide tube 116 is to guide the forward direction of the diameter gauge to prevent the diameter gauge from deviating and falling into the car body 111. The car body 111 is provided with a side movable baffle 113 on the side close to the diameter gauge conveying roller. The side movable baffle 113 is connected to the car body 111 through the side movable baffle mounting shaft 9. The top of the car body 111 A top fixed baffle 114 and a top movable baffle 115 are installed. The top movable baffle 115 is locked with a pin when working. When the diameter gauge is stuck between the end of the steel pipe and the car body 111, it can be disassembled to deal with abnormal conditions. After the diameter gauge is cleared, it first collides with the buffer bumper 112 and rebounds and falls into the car body 111. After the system receives the diameter gauge falling signal, the cylinder drives the side movable baffle mounting shaft 9 to lift the side movable baffle 113, and the diameter gauge falls into the side diameter gauge conveying roller and is sent to the lifting platform 2.

[0024] The diameter gauge conveying roller comprises a cylindrical conveying roller 4 and a V-shaped conveying roller 5 . The cylindrical conveying roller 4 is close to the lifting platform 2 . The diameter gauge blocking device 6 is located at the front section of the V-shaped conveying roller 5 close to the cylindrical conveying roller 4 .

[0025] The diameter gauge blocking device 6 includes a roller baffle frame 601 connected to the roller side plate 12, a roller baffle cylinder 602 is installed on the roller baffle frame 601, and the output end of the roller baffle cylinder 602 is connected to the roller baffle 603. The diameter gauge must first pass through the diameter gauge blocking device 6 before reaching the cylindrical conveying roller 4. When the system determines that a certain diameter gauge passes the roller baffle 603 position, the roller baffle cylinder 602 drives the roller baffle 603 to rise, the No. 1 reduction motor 10 stops, and the No. 2 reduction motor 7 starts, so that the remaining diameter gauges stop being transported, thereby ensuring that only one diameter gauge is transported to the cylindrical conveying roller 4.

[0026] The diameter transverse pushing device 3 includes a transverse pushing cylinder 301, and a transverse pushing bracket 302 is fixedly connected between the transverse pushing cylinder 301 and the roller side plate 12. When the system detects that the diameter gauge has reached the cylindrical conveying roller 4 and stopped, the transverse pushing cylinder 301 pushes the diameter gauge to the lifting platform 2, and at the same time, the roller baffle 603 of the diameter gauge blocking device 6 falls, and the No. 1 reduction motor 10 starts to convey the second diameter gauge, thereby realizing continuous conveyance of the diameter gauge.

[0027] The lifting platform 2 includes a lifting cylinder 201, and a diameter gauge lifting platform 202 is connected to the top of the lifting cylinder 201. A lifting bracket 303 is fixedly connected between the diameter gauge lifting platform 202 and the roller side plate 12. After the diameter gauge is lifted to a certain height, it is followed by subsequent precise positioning, pushing and blowing diameter processes, and the diameter gauge falls into the diameter gauge receiving trolley 11 again to realize the recycling of the diameter gauge.

[0028] A specific application of this embodiment is:

[0029] The diameter gauge passes through the diameter gauge guide tube 116 under the push of high-pressure gas, hits the buffer bumper 112 and rebounds, and then passes through the side movable baffle 113 to make its center line parallel to the center line of the diameter gauge conveying roller. After that, the side movable baffle 113 is opened under the drive of the cylinder to make the diameter gauge fall steadily onto the diameter gauge conveying roller, and the roller conveyor conveys the diameter gauge in the direction of the lifting platform 2. When the system detects that there is no diameter gauge on the cylindrical conveying roller 4 and the lifting platform 2 is at the lowest position, the roller baffle 603 of the diameter gauge blocking device 6 falls, and the diameter gauge is conveyed to the cylindrical conveying roller 4. Conveying roller 4, then the horizontal push cylinder 301 extends out and pushes it to the lifting platform 2. The diameter gauge lifting platform 202 lifts the diameter gauge to the required height under the action of the lifting cylinder 201. If the system finds that the cylindrical conveying roller 4 has a diameter gauge, the roller baffle 603 is lifted up by the roller baffle cylinder 602 to block other diameter gauges on the roller. At the same time, the No. 1 reduction motor 10 stops and the roller stops rotating until the system detects that there is no diameter gauge on the cylindrical conveying roller 4. The roller baffle 603 falls and the No. 1 reduction motor 10 starts, thereby ensuring the transportation of a single diameter gauge.
