DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection is a non-detachable connection, including but not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: choose welding connection for fixed connection and hinge connection for detachable connection.

[0024] Specific implementation method 1: Combination Figure 1-Figure 4 To illustrate this embodiment, the automatic steel pipe placing machine of this embodiment includes a steel pipe track 1, a chain transmission mechanism 2, a fork 3, a hydraulic lifting platform 4 and a loading rack 5. A hydraulic lifting platform 4 is arranged below the steel pipe track 1, and a chain transmission mechanism 2 is installed on the top of the hydraulic lifting platform 4. A plurality of forks 3 are arranged at equal intervals on the chain transmission mechanism 2, and the chain transmission mechanism 2 is located at the front side and / or the rear side of the steel pipe track 1.

[0025] The chain transmission mechanism 2 includes a frame 21, a fin chain 22, a driving sprocket 23, a driven sprocket 24 and a driving motor. The frame 21 is fixedly installed on the top of the hydraulic lifting platform 4. The driving sprocket 23 and the driven sprocket 24 are rotatably installed on the frame 21 through a rotating shaft. The driving sprocket 23 and the driven sprocket 24 are connected through the fin chain 22. A plurality of shift forks 3 are installed side by side on the fin chain 22. The output end of the driving motor is connected to the rotating shaft connected to the driving sprocket 23, that is, the driving sprocket 23 is driven to rotate by the driving motor, thereby driving the entire fin chain 22 to transmit.

[0026] The hydraulic lifting platform 4 is a hydraulic lifting platform driven by an oil cylinder 41. That is, the hydraulic lifting platform 4 also includes a base 42, a first arm 43, a second arm 44, a connecting shaft 45 and a lifting platform 46. The middle parts of the first arm 43 and the second arm 44 are connected to each other through the connecting shaft 45. One end of the first arm 43 is connected to the lifting platform 46 in a sliding manner. The other end of the first arm 43 is connected to the base 42 in a rotational manner. One end of the second arm 44 is connected to the base 42 in a sliding manner. The other end of the second arm 44 is connected to the lifting platform 46 in a rotational manner. The two ends of the oil cylinder 41 are connected to the base 42 and the lifting platform 46 in a rotational manner. When the oil cylinder 41 is stretched, the first arm 43 and the second arm 44 move crosswise, and one end of the first arm 43 and the second arm 44 slides relative to the lifting platform 46 and the base 42, respectively, and the lifting platform 46 rises. The same is true in reverse.

[0027] In addition, the automatic steel pipe feeding machine of this embodiment can also be provided with a sensor for counting, that is, measuring the number of steel pipes transferred from the loading rack 5 to the chain transmission mechanism 2. The sensor can be a rotary encoder, an infrared counter, etc.

[0028] The steel pipe track 1 includes a track frame 11, a transmission shaft 12, a track roller 13, a track motor 14, a pulley 15 and a transmission belt 16. A plurality of transmission shafts 12 are rotatably installed on the top of the track frame 11 through a belt seat bearing, and the plurality of transmission shafts 12 are arranged in parallel with equal intervals, and each two adjacent transmission shafts 12 are connected by two pulleys 15 and a transmission belt 16, that is, each transmission shaft 12 is equipped with two pulleys 15, one of the pulleys 15 on each transmission shaft 12 is connected to one of the pulleys 15 on the previous transmission shaft 12 through the transmission belt 16, and the other pulley 15 on each transmission shaft 12 is connected to the other pulley 15 on the next transmission shaft 12 through the transmission belt 16, and a track roller 13 is fixedly installed coaxially at one end of the transmission shaft 12, and the other end of any one of the transmission shafts 12 is connected to the output end of the track motor 14.

[0029] The working principle of the steel pipe track 1 is as follows: first, the track motor 14 drives the transmission shaft 12 connected to it to rotate. Due to the transmission setting of the pulley 15 and the transmission belt 16 between the multiple transmission shafts 12, the track motor 14 directly drives one transmission shaft 12 to drive the remaining transmission shafts 12 to rotate. At the same time, the track roller 13 rotates synchronously with the transmission shaft 12 to realize the track transmission of the steel pipe 6.

[0030] A chain transmission mechanism 2 is arranged between two adjacent track rollers 13. Figure 4 shown.

[0031] The loading rack 5 is provided with a detachable stopper 51, which can be mounted on the end of the top of the loading rack 5 through a clamping seat, so as to control the rolling of the steel pipe 6. When the steel pipe 6 needs to roll down automatically, it is only necessary to remove the detachable stopper 51, and vice versa.

[0032] The number of the chain transmission mechanisms 2 in this embodiment is multiple, and they can be installed and arranged on the front and rear sides of the steel pipe track 1 through the hydraulic lifting platform 4, or interlaced and arranged between two track rollers 13.

[0033] The specific working method of this embodiment is as follows: the steel pipes 6 are hoisted onto the loading rack 5, the bundled steel pipes 6 are opened, and the steel pipes 6 are evenly distributed on the loading rack 5 by gravity, and then the hydraulic lifting platform 4 is started, and the cylinder 41 lifts the hydraulic lifting platform 4 to a specified height.

[0034] Start the driving motor, which drives the chain transmission mechanism 2 to rotate. A shift fork 3 is installed on the fin chain 22. When rotating, the shift fork 3 shifts the steel pipe 6 dropped from the loading rack 5 into its groove. After the number of steel pipes 6 is counted, the detachable stopper 51 is installed back on the loading rack 5 to prevent the steel pipe 6 from rolling down automatically. Then the hydraulic lifting platform 4 descends, and the steel pipe 6 falls neatly onto the steel pipe track 1, and then the next process is carried out.

[0035] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined, and those skilled in the art can exhaust all possibilities based on the mathematical knowledge of arrangement and combination. Therefore, the present utility model will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present utility model.

[0036] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
