Description

Technical Field

[0001] This utility model relates to the field of casting transfer technology, specifically a casting transfer vehicle with a limiting function. Background Technology

[0002] In the casting production process, the transfer of castings is a crucial link. Traditional casting transfer vehicles are usually only equipped with a simple base plate and displacement wheels to carry and move castings. However, in the actual transfer process, because some castings are regular columnar in shape, they may be affected by external forces such as bumps and vibrations during transportation, making it difficult for the castings to remain stable on the transfer vehicle, and they are very prone to displacement, shaking or even falling.

[0003] Existing transfer vehicles often lack effective limiting measures and cannot reliably fix castings. Although some transfer vehicles are equipped with some limiting structures, most of them use relatively simple external blocking methods. For castings with regular round shapes or hollow internal structures, it is difficult to achieve precise and stable limiting. In the process of transfer, once the casting is displaced significantly, the limiting structure is prone to failure, which poses a serious threat to the quality of the casting and the safety of transfer. Utility Model Content

[0004] The purpose of this utility model is to provide a casting transfer vehicle with a limiting function to solve the problem of unstable limiting of castings during the transfer process mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a casting transfer vehicle with a limiting function, including a base plate, a displacement wheel installed on the lower surface of the base plate, a support seat fixedly provided on the upper surface of the base plate, and a limiting mechanism provided on the surface of the support seat. By internally supporting and limiting the two ends of the casting, the stability of the casting during the transfer process is ensured.

[0006] The limiting mechanism includes: a pressure chamber located inside the middle section of the support, with a piston disc inside the pressure chamber. An abutment plate is fixedly connected to the upper end of the piston disc, and the upper end of the abutment plate penetrates the upper surface of the middle section of the support. Piston chambers are located inside both ends of the support, and a guide groove is provided between the piston chamber and the pressure chamber. A piston square plate is located inside each piston chamber, with a gear fixedly connected to one end of the piston square plate. Rotating gears are installed inside both ends of the support, and rotating rods are fixedly mounted on the outer surfaces of the gears. The upper end of the rotating rod... A fixed port is connected to a central block, and a support plate is set inside the central block. The other end of the support plate penetrates the outer surface of the central block. Limiting blocks are fixedly set inside both ends of the support. The inner surface of one end of the guide channel is penetrated by one end of the connecting channel, and the other end of the connecting channel penetrates the outer surface of the support. One end of the connecting channel penetrating the outer surface of the support is fixedly connected to one end of a spring tube, and the other end of the spring tube is fixedly connected to a rotating rod. The end of the spring tube connected to the rotating rod penetrates the inner surface of the rotating rod. The upper end of the rotating rod is penetrated by a locking bolt.

[0007] The limiting mechanism further includes: a clearance groove, which is formed on the upper surfaces of both ends of the support seat, and a sliding support rod is installed on the upper surfaces of both ends of the support seat, and a connecting rod is installed on the upper end of the support rod.

[0008] Preferably, the pressure chamber and the piston plate are connected by sliding friction, and a spring is connected between the pressure chamber and the piston plate. The end of the contact plate located outside the support is arc-shaped, and the arc-shaped end of the contact plate is in contact with the outer surface of the casting.

[0009] Using the above technical solution, when the casting is placed on the support, the contact plate can better fit with the outer surface of the casting. Under the action of the casting's gravity, the contact plate can drive the piston plate to slide in the pressure chamber, compress the spring, and pressurize the inside of the pressure chamber, providing power for the subsequent movement of components such as the rotating rod. At the same time, the arc design can increase the contact area with the casting, disperse the pressure, and avoid damage to the surface of the casting.

[0010] Preferably, the piston chamber and the piston square plate are connected by sliding friction, the rack is meshed with the gear, and the outer surface of the rotating rod is in contact with the outer surface of the limiting block.

[0011] Using the above technical solution, when the increased pressure in the pressure chamber is transmitted to the piston chamber, the piston square plate can slide smoothly in the piston chamber, thereby driving the rack to move. The meshing of the rack and gear can convert linear motion into gear rotation, driving the rotating rod to rotate, so that the rotating rod can accurately rotate to the position that fits with the limit stop, ensuring the accuracy and stability of the rotating rod's rotation angle, and providing reliable support and positioning for the support plate to enter the interior of both ends of the casting.

[0012] Preferably, the rotating rod is hollow, and one end of the rotating rod is connected to the internal cavity of the central block where the support plate is located. The support plate and the internal cavity of the central block are connected by sliding friction, and one end of the support plate is in contact with the inner surface of the casting.

[0013] By adopting the above technical solution, the hollow design of the rotating rod facilitates the transmission of pressure to the internal cavity of the central block, pushing the support plate to slide within the central block and making it fit against the inner surface of the casting, thereby achieving internal support and limiting of the casting. The sliding friction connection method ensures that the support plate can slide flexibly when under force, closely fitting the inner side of the casting, enhancing the limiting effect, and will not affect the rotation of the rotating rod or the stability of the overall structure.

[0014] Preferably, the locking bolt penetrates the inner surface of the upper end of the rotating rod, and the locking bolt and the rotating rod are connected by a thread, and the diameter of the locking bolt is larger than the inner diameter of the hollow part of the rotating rod.

[0015] Using the above technical solution, after the support plate completes the support and limit of the casting, rotating the locking bolt can lock the internal cavity of the rotating rod, preventing the support plate from transmitting pressure in the reverse direction to the pressure chamber when under force, avoiding the casting from being lifted due to pressure changes in the pressure chamber, ensuring that the casting always maintains a stable placement state during transportation, and improving the reliability of the limit.

[0016] Preferably, the end of the supporting ball rod connected to the support seat is spherical, the supporting ball rod and the connecting rod are threadedly connected, and the connecting rod is threadedly connected to the upper end of the rotating rod.

[0017] The above technical solution utilizes a spherical design at the connection end between the support rod and the support seat, allowing it to slide flexibly on the support seat and facilitating position adjustment. The threaded connection method enables easy installation and disassembly. Once the rotating rod has rotated to its position, rotating the connecting rod allows the support rod to provide lateral support to the rotating rod, enhancing its stability and thus improving the stability of the casting during transport, preventing the rotating rod from swaying or deforming due to uneven force.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the casting transfer cart with limiting function:

[0019] 1. By gradually placing the casting on the support and then pressing the contact plate, the contact plate can pressurize the inside of the pressure chamber through the piston plate, thereby pushing the rotating rod to rotate the center block and support plate to the inside of both ends of the casting. This allows the casting to be fully limited with the cooperation of the support and will not shake during transportation.

[0020] 2. Furthermore, by having the rotating rod flip up and then being supported laterally by the supporting club, the rotating rod can obtain a stable supporting force, thereby ensuring sufficient support for the rotating rod during casting swaying and guaranteeing the stability of the casting placement.

By internally supporting and limiting the two ends of the casting, the stability of the casting during the transfer process is ensured.

[0032] The limiting mechanism includes: a pressure chamber 4, which is located inside the middle section of the support 3, and a piston disc 5 is installed inside the pressure chamber 4. An abutment plate 6 is fixedly connected to the upper end of the piston disc 5, and the upper end of the abutment plate 6 penetrates the upper surface of the middle section of the support 3. Piston chambers 7 are located inside both ends of the support 3, and a guide groove 8 is provided between the piston chamber 7 and the pressure chamber 4. A piston square plate 9 is installed inside the piston chamber 7, and a gear 10 is fixedly connected to one end of the piston square plate 9. Rotating gears 11 are installed inside both ends of the support 3, and a rotating rod 12 is fixedly installed on the outer surface of the gear 11. The upper end of the rotating rod 12 is fixedly connected to a middle... The center block 13 has a support plate 14 at one end inside, and the other end of the support plate 14 penetrates the outer surface of the center block 13. Limiting blocks 15 are fixedly installed inside both ends of the support seat 3. The inner surface of one end of the guide channel 8 is penetrated by one end of the connecting channel 16, and the other end of the connecting channel 16 penetrates the outer surface of the support seat 3. One end of the connecting channel 16 penetrating the outer surface of the support seat 3 is fixedly connected to one end of the spring tube 17, and the other end of the spring tube 17 is fixedly connected to the rotating rod 12. The end of the spring tube 17 connected to the rotating rod 12 penetrates the inner surface of the rotating rod 12, and the upper end of the rotating rod 12 is penetrated by the locking bolt 18.

[0033] The pressure chamber 4 and the piston plate 5 are connected by sliding friction, and a spring is connected between the pressure chamber 4 and the piston plate 5. The end of the contact plate 6 located outside the support 3 is arc-shaped, and the arc-shaped end of the contact plate 6 is in contact with the outer surface of the casting.

[0034] The piston chamber 7 and the piston square plate 9 are connected by sliding friction, the rack 10 is meshed with the gear 11, and the outer surface of the rotating rod 12 is in contact with the outer surface of the limiting block 15.

[0035] The rotating rod 12 is hollow, and one end of the rotating rod 12 is connected to the cavity inside the central block 13 where the support plate 14 is located. The support plate 14 and the cavity inside the central block 13 are connected by sliding friction. One end of the support plate 14 is in contact with the inner surface of the casting.

[0036] The locking bolt 18 penetrates the inner surface of the upper end of the rotating rod 12, and the locking bolt 18 is threadedly connected to the rotating rod 12. Furthermore, the diameter of the locking bolt 18 is larger than the inner diameter of the hollow part of the rotating rod 12.

[0037] During use, the base plate 1 is moved to the predetermined position by the displacement wheel 2, and then gradually lifted and placed on the support seat 3. During the process, the contact plate 6 is pressed and drives the piston circular plate 5 to slide inside the pressure chamber 4, compressing the air inside the pressure chamber 4, which increases the pressure inside the pressure chamber 4.

The support plate 14 abuts against the inner surface of the casting for support. At this time, the locking bolt 18 is rotated to lock the cavity inside the rotating rod 12, so that the support plate 14 will not transmit the pressure to the pressure chamber 4 in the reverse direction when it is under force, causing the casting to be lifted.

[0042] After the rotating rod 12 is rotated into position, the support ball rod 20 is rotated so that it is disengaged from the relief groove 19 and faces the upper end of the rotating rod 12. At this time, the connecting rod 21 is rotated, and the connecting rod 21 is gradually moved out through the threaded connection with the support ball rod 20 and threadedly connected to the rotating rod 12, so that the support ball rod 20 can provide auxiliary support for the rotating rod 12 from both sides.
