Abstract
Description
Technical Field
[0001] The utility model relates to a cast pipe processing device, in particular to a translation feeding mechanism for a cast pipe processing trolley. Background Art
[0002] In the production process of ductile iron pipes, it is often necessary to use a translational feeding trolley to transport processing equipment such as chamfering machines and socket cleaning machines. That is, when the ductile iron pipe is in a rotating state, the translational feeding trolley drives the processing equipment to move toward the ductile iron pipe and process it; when the processing equipment is finished, the translational feeding trolley drives the processing equipment to separate from the ductile iron pipe and return to its original position, so that the ductile iron pipe enters the next station under the action of transportation. At the same time, since the processing equipment needs to maintain a continuous fit with the ductile iron pipe during the processing process, the translational feeding trolley also needs to apply continuous extrusion force to the processing equipment during the processing process, so that the processing equipment can stably fit the ductile iron pipe under the extrusion action.
[0003] On the basis of the above, the current translational feeding trolley generally realizes the translational conveying and squeezing functions of the processing equipment through the jacking equipment such as oil cylinders and air cylinders. However, since the processing equipment rotates in the opposite direction to the ductile iron pipe during the processing, when the two come into contact, the ductile iron pipe will exert an outward force on the processing equipment, causing the processing equipment to vibrate and bounce off; the jacking equipment needs to overcome this force and maintain the continuous fit between the processing equipment and the ductile iron pipe. This causes the jacking equipment to bear the force from the processing equipment for a long time, and it is easy to cause the jacking equipment to be damaged by the force, thereby increasing the manufacturer's equipment loss.
[0004] Therefore, a non-breakable translation feeding mechanism is needed. Utility Model Content
[0005] The utility model aims to provide a translation feeding mechanism for a pipe casting processing trolley, which can prevent the telescopic rod from being damaged by force after long-term use.
[0006] The technical solution of the utility model is as follows: a translational feeding mechanism for a cast pipe processing trolley comprises a base, a feeding trolley is slidably connected to the base, a telescopic rod connected to the base is provided at one end of the feeding trolley, a conveying chain is connected to the other end of the conveying chain, a counterweight block hanging downward is connected to the end of the conveying chain, and the counterweight block applies a horizontal driving force to the feeding trolley after hanging.
[0007] In the aforementioned translational feeding mechanism for the cast pipe processing trolley, the end of the feeding trolley close to the cast pipe is the front end, the telescopic rod is located at the front end of the feeding trolley, the end of the telescopic rod is connected to a push plate, the outside of the push plate and the side wall of the feeding trolley are in contact with each other; the conveying chain is connected to the front end of the feeding trolley, and the conveying chain and the telescopic rod are staggered left and right.
[0008] In the aforementioned translational feeding mechanism for the cast pipe processing trolley, the end of the feeding trolley close to the cast pipe is the front end, the telescopic rod is located at the rear end of the feeding trolley, and the end of the telescopic rod is detachably connected to the feeding trolley; the conveying chain is connected to the front end of the feeding trolley, and the middle part of the conveying chain extends to the rear end of the feeding trolley through the guide sprocket and is connected to the counterweight block.
[0009] In the aforementioned translational feeding mechanism for the cast pipe processing trolley, the end of the telescopic rod is connected to the feeding trolley via a sliding rod, and the sliding rod is respectively connected to a limiting member and a traction member, and a sliding groove is left between the limiting member and the traction member for the feeding trolley to slide freely. The feeding trolley is connected to a transmission plate located in the sliding groove, and a circular hole is provided in the middle of the transmission plate for the sliding rod to pass through.
[0010] Compared with the prior art, the utility model cooperates with the structure of the telescopic rod, the conveying chain and the counterweight block so that the telescopic rod can only translate and convey the feeding trolley when it is in a non-working state. When the feeding trolley is in a working state, the gravity of the counterweight block is used to drive the feeding trolley forward, thereby achieving a continuous pressure effect on the feeding trolley and effectively preventing the damage of the telescopic rod caused by the force. On this basis, the utility model limits the connection structure of the telescopic rod and the conveying chain, so that the feeding trolley can realize its translational feeding function in both states, thereby facilitating the manufacturer to install and connect the feeding trolley according to needs, thereby improving the versatility of the utility model.
[0011] In addition, the utility model optimizes the connection structure between the telescopic rod and the feeding trolley, so that when the feeding trolley is in a working state, its transmission plate can be located in the slide groove between the limit piece and the traction piece, thereby leaving space for the translation of the feeding trolley under the driving action of the counterweight block, and effectively preventing the telescopic rod from contacting the feeding trolley during operation and causing damage, thereby further improving the stability of the utility model.
[0012] Therefore, the utility model can prevent the telescopic rod from being damaged by force after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The end of the conveying chain 4 is rotatably connected to a vertical rod, and the counterweight blocks 5 are multiple in number and sleeved on the vertical rod, so that the manufacturer can adjust the number of counterweight blocks 5 according to demand, thereby improving the processing effect of the processing equipment on the cast pipe.
[0020] The end of the feeding trolley 2 close to the casting pipe is the front end, the telescopic rod 3 is located at the rear end of the feeding trolley 2, and the end of the telescopic rod 3 is detachably connected to the feeding trolley 2; the conveying chain 4 is connected to the front end of the feeding trolley 2, and the middle part of the conveying chain 4 extends to the rear end of the feeding trolley 2 through the guide sprocket 7 and is connected to the counterweight block 5, and the guide sprocket 7 is rotatably connected to the base 1.
[0021] The end of the telescopic rod 3 is connected to the feeding trolley 2 via a sliding rod 8, and a limiting member 9 and a pulling member 10 are respectively connected to the sliding rod 8. The limiting member 9 is used to limit the feeding trolley 2 at the rear; both the limiting member 9 and the pulling member 10 can be made of nuts or discs threadedly connected to the sliding rod 8, and a slide groove is left between the limiting member 9 and the pulling member 10 for the feeding trolley 2 to slide freely. The feeding trolley 2 is connected to a transmission plate 11 located in the slide groove, and a circular hole for the sliding rod 8 to pass through is provided in the middle of the transmission plate 11, and a gap is left between the circular hole and the sliding rod 8.
[0022] A rectangular frame for placing the counterweight 5 is provided at the rear end of the base 1, and a transparent cover is detachably connected around the rectangular frame, thereby effectively preventing outsiders from contacting the counterweight 5 and causing safety hazards.
[0023] In the non-working state of this embodiment, the telescopic rod 3 is in a retracted state and the feeding trolley 2 is limited by the traction member 10, so that the feeding trolley 2 is away from the casting pipe.
