Description

TECHNICAL FIELD

[0001] The present application relates to the field of conveying facilities, in particular to a seamless pipe falling system for heat exchangers. BACKGROUND

[0002] As the core equipment in the field of material conveying, the conveyor is a mechanical device that can realize continuous conveying of materials on a specific line, also known as a continuous conveyor. This kind of equipment occupies an important position in many industries due to its outstanding performance advantages. It not only has strong conveying capacity and can efficiently handle a large amount of materials, but also can realize long-distance material transportation, reducing the need for intermediate transfer. More importantly, the conveyor can flexibly integrate multiple process operations during the conveying of materials. The seamless pipe of the heat exchanger often uses the conveyor for conveying during the processing.

[0003] In actual production scenarios, when the seamless pipe is conveyed by the conveyor, falls off the conveyor belt and is stacked, a rubber pad needs to be placed between the upper and lower seamless pipes to separate them. However, the current operation of placing the rubber pad mostly relies on manual work by workers. This process is not only tedious and time-consuming, but also requires workers to frequently bend over, stand up and repeatedly perform the same actions, which greatly increases the labor intensity of the workers. SUMMARY

[0004] The purpose of the present application is to solve the shortcomings in the background art and provide a seamless pipe falling system for heat exchangers.

The guide post plays a guiding role on the fixed frame. The anti-separation cap plays a role in preventing the fixed frame and the guide post from separating. When the push magnet is moving towards the seamless tube under the action of magnetic force, the fixed frame will be on the protective cap when the two are about to contact, so as to prevent the push magnet from continuing to move, so as to avoid damage caused by the impact between the push magnet and the seamless tube during movement.

The shell holder plays a role in fixing the fixed shell. The pin cap is pushed by the fixed spring. The fixed shell plays a role in bearing the fixed pin. The fixed pin plays a role in fixing the ear seat and the extension ear together. The fixed spring plays a role in pushing the fixed pin into the ear seat and the extension ear. By pulling the pull ring, the fixed pin can be slidingly moved in the fixed shell, so that the fixed pin is separated from the ear seat and the extension ear, so that the frame door can be opened.

[0011] Preferably, the reset member comprises a threaded rod rotatably installed at the rear end surface of the seat, a plurality of threaded sleeves are screwed on the outer surface of the threaded rod, the spacing between the plurality of threaded sleeves is the same as the spacing between the plurality of material frames, the upper end of the threaded sleeve is fixedly installed with a stepped frame, and the rear end of each of the plurality of load cases extends a jacking rod, and the end portion of the jacking rod is aligned with the stepped frame. The threaded rod plays a role in driving the plurality of threaded sleeves to move synchronously. Rotating the threaded rod can drive the threaded sleeves to move, thereby driving the stepped frame to move, at this time, the guide sleeve slides on the guide rod to guide the stepped frame, so that the plurality of jacking rods are pushed through the moved stepped frame, so that the plurality of pushing magnets on the plurality of material frames can be reset to be stepped at the same time, thereby driving the plurality of first rubber pads to be reset to be stepped at the same time, which avoids the cumbersome phenomenon of resetting the plurality of pushing magnets and the first rubber pad one by one.

The guide rod and the guide sleeve play a role in guiding the stepped frame.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] 1. When the seamless tube is conveyed into the guide hopper by the conveyor and rolls down the bottom of the material frame, the bottommost pushing magnet will move towards the seamless tube due to its attraction. Simultaneously, the fixed bracket slides on the guide post, causing the bottommost rubber pad to move above the seamless tube. During this process, the lug pushes the multiple pushing magnets above. At this point, the second-to-last pushing magnet at the bottom is just close to the material frame. Then, the second seamless tube rolls down into the material frame and lands on the bottommost rubber pad, thus separating the two seamless tubes. The second-to-last pushing magnet at the bottom will move towards the second seamless tube due to its attraction, thus moving the second-to-last rubber pad at the bottom to above the second seamless tube. During this process, the lever pushes the multiple pushing magnets above again. At this time, the third-to-last pushing magnet at the bottom is just close to the material frame, and then the third seamless tube falls down. This process is repeated, so that multiple seamless tubes are stacked together while the rubber pads are automatically placed between the upper and lower seamless tubes. This process does not require manual placement by workers, thus effectively reducing the labor intensity of workers.

[0015] 2. When the material frame is full, the positioning post fixed by the fixing magnet can be pulled out from the positioning hole on the T-shaped frame. Then, push the seat. At this time, the T-shaped frame slides in the sliding sleeve for guidance. When the other positioning hole on the T-shaped frame is aligned with the positioning post, insert the positioning post into the other positioning hole. This will allow the other material frame to be aligned with the guide bucket for material dropping. The process is simple and convenient for material dropping.

[0016] 3. By rotating the threaded rod, the threaded sleeve can be moved, which in turn drives the stepped frame to move. At this time, the guide sleeve slides on the guide rod to guide the stepped frame. The moving stepped frame pushes multiple top rods, so that multiple pushing magnets on multiple material frames can be reset to a stepped shape at the same time. This drives multiple No. 1 rubber pads to be reset to a stepped shape at the same time. This process avoids the tedious phenomenon of resetting multiple pushing magnets and No. 1 rubber pads one by one, which effectively facilitates the next use. Attached Figure Description
