Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, specifically to a transfer trolley for finished air duct processing products with shock absorption function. Background Technology

[0002] In industrial production, shock-absorbing transfer trolleys are key tools for material handling. For finished ductwork products, their material and structural characteristics make them highly susceptible to damage from vibration during transport. Shock-absorbing transfer trolleys can effectively buffer vibrations and ensure the quality of the finished product.

[0003] Traditional shock-absorbing transfer trolleys are commonly used in the transfer of finished ductwork. They typically achieve a certain degree of shock absorption by installing shock-absorbing components such as springs at the bottom of the trolley and using appropriate wheels. When in use, workers place the finished ductwork directly on the trolley platform and secure it with ropes or other simple bindings before transferring it within the workshop or between factories.

[0004] However, existing transfer trolleys have certain limitations in use. When transferring ductwork, the ducts are placed directly on the trolley platform and simply secured with ropes, lacking internal support and making it difficult to stabilize the duct's inner wall. During transport, the ducts are prone to relative displacement due to the trolley's shaking and bumps, leading to collisions with the trolley or other objects, causing scratches, dents, or even deformation on the duct surface, affecting the duct's quality and performance. Furthermore, due to the diverse specifications of ductwork, traditional fixing methods are difficult to adjust flexibly to accommodate different pipe diameters, reducing transfer efficiency and applicability. Therefore, a ductwork processing finished product transfer trolley with shock absorption function is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a duct processing finished product transfer trolley with shock absorption function. This effectively solves the problems of existing technologies where ducts are directly placed on the trolley platform and simply tied and fixed with ropes, which lacks internal support for the ducts, making it difficult to achieve stability of the duct inner wall. It also addresses the issue that traditional fixing methods are difficult to flexibly adjust to meet the needs of different duct diameters due to the variety of duct specifications.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] See attached document Figure 1-5 A trolley for transferring finished ductwork products with shock absorption function, comprising:

[0031] The base 1 and the protective railing 2 are mounted on top of the base 1. The base 1 has shock-absorbing casters at its bottom. The shock absorption is achieved by adding spring-loaded shock-absorbing devices at the connection between the casters and the base 1 to effectively buffer vibrations generated during transport and reduce damage to the finished ductwork. By pushing or pulling the trolley, the casters rotate, moving the entire trolley and the ductwork it carries to the designated position. A fixing plate 201 is welded to the outer wall of the protective railing 2. The fixing plate 201 serves as the mounting base for the support components, securely connecting the support rod 3 to the protective railing 2, allowing the support components to move with the trolley and support the ductwork. The fixing plate 201 is equipped with a support component for internally tightening the ductwork. This support component includes:

[0032] The support rod 3 is fixedly welded to the fixing plate 201. It is a cylindrical metal rod with certain strength and rigidity.

[0033] Multiple sets of abutment plates 4 are provided. A connecting block 401 is fixedly provided at the bottom of the abutment plate 4. The connecting block 401 is rotatably connected to one end of the first rotating plate 301 and the second rotating plate 302 respectively through a pin. The other ends of the first rotating plate 301 and the second rotating plate 302 are rotatably connected to the outer wall of the support rod 3 respectively through a pin. The first rotating plate 301 and the second rotating plate 302 are provided on the left and right sides of the support rod 3. The first rotating plate 301 and the second rotating plate 302 cooperate with each other to constrain and guide the movement trajectory of the abutment plate 4, ensuring its stable movement. Multiple sets of abutment plates 4 are inserted into the inner wall of the air duct. By moving outward, the abutment plates 4 are pressed against the inner wall of the air duct, and the air duct is fixed from the inside by friction, thus completing the tightening action.

[0034] An adjustment unit is mounted on the support rod 3. The adjustment unit is used to drive the abutment plate 4 to move in a direction perpendicular to the axis of the support rod 3.

[0035] A movable ring block 5 is movably sleeved on the outer wall of the support rod 3. The outer wall of the movable ring block 5 is rotatably connected to a third rotating plate 303 via a pin. The other end of the third rotating plate 303 is rotatably connected to the outer wall of the connecting block 401 via a pin. When the movable ring block 5 moves on the support rod 3, the third rotating plate 303 will rotate around the pin, driving the connecting block 401 and the abutment plate 4 to move. It works in conjunction with the first rotating plate 301 and the second rotating plate 302 to adjust the position of the abutment plate 4.

[0036] The outer wall of the support rod 3 is provided with a guide groove 304, and a guide block 501 is movably inserted into the inner wall of the guide groove 304. One end of the guide block 501 is fixedly connected to the inner wall of the moving ring block 5. The guide groove 304 and the guide block 501 cooperate to guide and limit the movement, ensuring that the moving ring block 5 can only move along the axial direction of the support rod 3, and preventing the moving ring block 5 from deviating during the movement.

[0037] The adjustment unit includes a drive block 502 and a guide screw 6. The guide screw 6 is rotatably connected to the inner cavity of the support rod 3 via a bearing. The drive block 502 is threadedly connected to the outer wall of the guide screw 6, and the outer wall of the drive block 502 is fixedly connected to the other end of the guide block 501. In use, the rotation of the guide screw 6 causes the drive block 502 to move, which in turn causes the guide block 501 to move, thereby causing the moving ring block 5 to move on the support rod 3. The movement is transmitted to the abutment plate 4 through the third rotating plate 303, thereby adjusting the position of the abutment plate 4.

[0038] An adjustment handle 601 is rotatably inserted into the outer wall of the support rod 3, and the adjustment handle 601 is fixedly connected to the guide screw 6, providing the operator with a point of force to rotate the guide screw 6, so that the operator can manually adjust the rotation of the guide screw 6, thereby realizing the adjustment of the position of the abutment plate 4. When in use, the operator holds the adjustment handle 601 and rotates it. Since the adjustment handle 601 is fixedly connected to the guide screw 6, it will drive the guide screw 6 to rotate together.

[0039] A rotating disk 602 is fixedly mounted on the outer wall of the adjusting handle 601, and a through hole 603 is provided through the outer wall of the rotating disk 602. Multiple sets of through holes 603 are provided, and the through holes 603 will align with the positioning holes 605 at different positions as the rotation proceeds, providing multiple selectable positions for locking to adapt to the state after tightening ducts of different diameters. A fixing screw 604 is movably inserted into the inner wall of the through hole 603. A positioning hole 605 is provided on the outer wall of the support rod 3, and the fixing screw 604 is threaded into the positioning hole 605. In use, when the adjusting handle 601 is adjusted to a suitable position, the positioning hole 605 is aligned with the corresponding through hole 603. The fixing screw 604 is inserted into the corresponding through hole 603 and tightened into the positioning hole 605. Through the threaded connection between the fixing screw 604 and the positioning hole 605, the rotating disk 602 and the adjusting handle 601 are fixed to the support rod 3 for locking, reducing the phenomenon of reverse loosening caused by vibration.

[0040] A protective pad 402 is fixedly installed on the outer wall of the clamping plate 4 to protect the inner wall of the air duct and prevent the clamping plate 4 from directly contacting the inner wall of the air duct and causing scratches or damage to the inner wall of the air duct during the clamping process.

[0041] Working principle:

[0042] In use, the duct is fitted over the support rod 3, and then the adjusting handle 601 is rotated, causing the guide screw 6 to rotate. The driving block 502 is threaded onto the outer wall of the guide screw 6 and fixedly connected to the guide block 501. The guide block 501 is inserted into the guide groove 304 on the outer wall of the support rod 3. Therefore, the rotation of the guide screw 6 causes the driving block 502 to move, which in turn causes the guide block 501 and the moving ring block 5 to move along the axial direction of the support rod 3. Through the moving ring block 5, the third rotating plate 303 rotatably connected to its outer wall will rotate around the pin, causing the connecting block 401 and the abutment plate 4 to move. At the same time, the connecting block 401 is also connected to the support rod 3 via the first rotating plate 301 and the second rotating plate 302. The rod 3 is rotatably connected, and the first rotating plate 301 and the second rotating plate 302 cooperate with each other to constrain and guide the stable movement of the clamping plate 4, so that multiple sets of clamping plates 4 move outward and press against the inner wall of the air duct. The air duct is fixed from the inside by friction. After adjusting to the appropriate position, the fixing screw 604 is inserted into the through hole 603 on the rotating disk 602 that is aligned with the positioning hole 605 and tightened in the positioning hole 605. The adjusting handle 601 is locked to prevent it from turning back and loosening due to vibration. The protective pad 402 on the outer wall of the clamping plate 4 can protect the inner wall of the air duct and prevent scratches or damage. Then, push or pull the trolley, and the moving wheels at the bottom of the base 1 rotate, driving the entire trolley and the air duct it carries to move to the designated position, completing the transfer and support work of the air duct.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
