Description

Technical Field

[0001] This application relates to the field of material handling equipment technology, and in particular to a material handling device for loading and unloading heavy objects in civil engineering. Background Technology

[0002] Logs are a common interior decoration material in building materials. They refer to logs that are cut into certain lengths according to standard or special specifications for size, shape, and quality.

[0003] During the loading and unloading process, logs are generally handled manually or by cranes and forklifts. Logs are heavy and difficult to handle, so manual handling is labor-intensive, inefficient, and costly. Using cranes and forklifts is very limited by space. Cranes and forklifts are difficult to access in small and complex work areas, and the cost of operating large machinery is also high, which increases the handling cost. Utility Model Content

[0004] To address the issue of high handling costs during the loading and unloading of logs, this application provides a heavy-duty loading and unloading handling device for civil engineering.

[0005] The technical solution of the heavy object loading and unloading device for civil engineering provided in this application is as follows:

[0006] A heavy-duty loading and unloading device for civil engineering includes a base, a mounting base, a first rotating shaft, a first connecting rod, a second connecting rod, a drive mechanism, and a clamping mechanism. The mounting base is disposed on the base. The first rotating shaft is rotatably connected to the mounting base in a transverse direction. The first connecting rod and the second connecting rod are perpendicularly connected to the first rotating shaft at an included angle. The drive mechanism is disposed on the mounting base and is used to drive the first connecting rod to rotate around the first rotating shaft. The clamping mechanism is disposed on the second connecting rod and is used to clamp logs.

[0007] By adopting the above technical solution, the logs are clamped by the clamping mechanism during use. Then, the drive mechanism drives the first connecting rod to rotate around the first rotating shaft, which in turn drives the second connecting rod to rotate synchronously around the first rotating shaft. This allows the logs clamped on the second connecting rod to be transported, thus realizing the functions of clamping and transporting logs. Compared with manual handling, this reduces the labor intensity of workers and increases the handling efficiency. Compared with using forklifts, cranes, and other machinery, it reduces the limitation of site space, makes the use more flexible, and improves the problem of high handling costs during the loading and unloading of logs.

[0008] Optionally, the driving mechanism includes a linear drive member, the fixed end of which is rotatably connected to the mounting base about the lateral direction, and the movable end of which is rotatably connected to the end of the first connecting rod away from the first rotating shaft about the lateral direction.

[0009] By adopting the above technical solution, by extending or shortening the movable end of the linear drive component, the end of the first connecting rod that is away from the first rotating shaft can be driven to move away from or closer to the fixed end of the linear drive component. Since the positions of the first rotating shaft and the linear drive component are fixed, the extension or shortening of the movable end of the linear drive component can achieve the functional requirement of driving the first connecting rod to rotate around the first rotating shaft. The structure is simple and the driving method is stable and reliable.

[0010] Optionally, one end of the mounting base is rotatably connected to the base, the rotation axis of the mounting base is parallel to the first rotation axis, and the base is provided with an adjustment mechanism for adjusting the rotation angle of the mounting base.

[0011] By adopting the above technical solution, the height of the clamping mechanism on the mounting base can be adjusted by adjusting the rotation angle of the mounting base through the adjustment mechanism, thereby adapting to the loading and unloading needs of logs of different heights and improving the practicality of the handling device of this application.

[0012] Optionally, the adjustment mechanism includes a third link, a slider, and a screw. The slider is slidably connected to the base along a direction perpendicular to the rotation axis of the mounting base. One end of the third link is rotatably connected to the mounting base, and the other end of the third link is rotatably connected to the slider. A fixing block is provided on the base. The screw is inserted into the fixing block along the sliding direction and is threadedly connected to the fixing block. The end of the screw is rotatably connected to the slider around its own axis.

[0013] By adopting the above technical solution, the third link and the mounting base form a triangular stable structure. By rotating the screw, the slider can be moved, thereby causing the third link to swing, thus realizing the angle adjustment of the mounting base. The structure is simple and the adjustment is convenient. Moreover, the threaded connection between the screw and the fixed block also enables the screw to form a self-locking mechanism, thereby improving the stability of the overall structure.

[0014] Optionally, the clamping mechanism includes a fixed plate and a pneumatic gripper. The fixed plate is fixedly connected to the second connecting rod, and the pneumatic gripper is disposed on the fixed plate. An extension chuck is detachably connected to the clamping part of the pneumatic gripper.

[0015] By adopting the above technical solution, the pneumatic gripper and the extension chuck are designed to stably clamp the logs simply by activating the pneumatic gripper, making the clamping method simple and reliable. The detachable connection of the extension chuck allows for timely replacement of the type and size of the extension chuck according to the size and shape of the logs, further improving the applicability of the clamping mechanism.

[0016] Optionally, a sliding seat is slidably connected to the fixed plate, the pneumatic gripper is fixed on the sliding seat, a baffle is provided on the fixed plate, an electric telescopic rod is fixed on the fixed plate, and the movable end of the electric telescopic rod is fixedly connected to the baffle.

[0017] By adopting the above technical solution, the sliding seat and the electric telescopic rod are designed to be coordinated, making the position of the pneumatic gripper relative to the fixed plate adjustable. This allows the pneumatic gripper to clamp logs at different positions at the same height, improving the flexibility and adaptability of the handling device.

[0018] Optionally, the base has multiple legs at its bottom, and the legs have casters at their bottoms.

[0019] By adopting the above technical solution, the outriggers and casters enable the entire device to have better mobility and stability, facilitating rapid movement between different work locations. At the same time, the outriggers can provide support on uneven ground, ensuring the stability of the handling device during operation.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. During use, the logs are clamped by the clamping mechanism, and then the first connecting rod is driven to rotate around the first rotating shaft by the drive mechanism, which drives the second connecting rod to rotate synchronously around the first rotating shaft, thereby driving the logs clamped on the clamping mechanism on the second connecting rod to rotate, thus realizing the handling of logs. Compared with manual handling and mechanical handling using forklifts and cranes, the handling cost is reduced.

[0022] 2. The coordinated arrangement of the mounting base and the adjustment mechanism allows the height of the clamping mechanism on the mounting base to be adjusted by adjusting the rotation angle of the mounting base through the adjustment mechanism, thereby adapting to the loading and unloading needs of logs of different heights and improving the practicality of the handling device of this application.

[0023] 3. The matching configuration of the sliding seat, baffle and electric telescopic rod makes the position of the pneumatic gripper relative to the fixed plate adjustable, thereby enabling the pneumatic gripper to clamp logs at different positions at the same height, improving the flexibility and adaptability of the handling device.

[0028] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0029] This application discloses a heavy-duty loading and unloading device for civil engineering. (Refer to...) Figure 1 The civil engineering heavy object loading and unloading handling device includes a base 1, a mounting base 2, a first rotating shaft 3, a first connecting rod 4, a second connecting rod 5, a drive mechanism 6, and a clamping mechanism 7.

[0030] The base 1 has four support legs 11 at its bottom corners, and each support leg 11 has a self-locking caster wheel 12 at its bottom. One end of the mounting base 2 is rotatably connected to the base 1, and the base 1 has an adjustment mechanism for adjusting the rotation angle of the mounting base 2. A support plate 21 is fixedly connected to the mounting base 2. A first rotating shaft 3 is rotatably connected to the top of the support plate 21 around its own axis. The first rotating shaft 3 is parallel to the rotation axis of the mounting base 2. A first connecting rod 4 and a second connecting rod 5 are both vertically welded and fixed to the periphery of the first rotating shaft 3, forming an angle. In this embodiment, the angle between the first connecting rod 4 and the second connecting rod 5 is 120°. A drive mechanism 6 is mounted on the mounting base 2 and is used to drive the first connecting rod 4 to rotate around the axis of the first rotating shaft 3. A clamping mechanism 7 is mounted on the second connecting rod 5 and is used to clamp the log.

[0031] In use, the logs are clamped by the clamping mechanism 7, and then the drive mechanism 6 drives the first connecting rod 4 to rotate around the axis of the first rotating shaft 3, which in turn drives the second connecting rod 5 to rotate synchronously around the axis of the first rotating shaft 3. This causes the logs clamped on the clamping mechanism 7 to flip, thus realizing the clamping and handling function of the logs. Compared with manual handling, this reduces the labor intensity of workers and increases handling efficiency. Compared with using forklifts and cranes, it reduces the limitation of site space, making it more flexible and improving the problem of high handling costs during the loading and unloading of logs. Furthermore, the adjustable mechanism allows the height of the clamping mechanism 7 on the mounting base 2 to be adjusted by adjusting the rotation angle of the mounting base 2, thereby adapting to the loading and unloading needs of logs of different heights and improving the practicality of the handling device of this application.

[0032] The adjustment mechanism includes a first slide rail, a third connecting rod, a slider, and a screw. The first slide rail is fixed on the base 1. The slider is slidably connected within the first slide rail in a direction perpendicular to the rotation axis of the mounting base 2. One end of the third connecting rod is rotatably connected to the mounting base 2, and the other end is rotatably connected to the slider. The swing direction of the third connecting rod is the same as the swing direction of the mounting base 2. A fixing block 13 is provided on the upper surface of the base 1. The screw is inserted into the fixing block 13 along the slider's movement direction and is threadedly connected to the fixing block 13. The end of the screw is rotatably connected to the slider around its own axis.

[0033] The base 1, mounting base 2, and third connecting rod form a stable triangular structure. Rotating the screw moves the slider, which in turn causes the third connecting rod to swing, thus adjusting the angle of mounting base 2 relative to base 1. The structure is simple and easy to adjust. Furthermore, the self-locking property of the threaded connection between the screw and the fixing block 13 makes the slider more stable, thereby improving the overall structural stability.

[0034] The drive mechanism 6 includes a linear drive component 61. For example, the linear drive component 61 is a telescopic cylinder. The fixed end of the linear drive component 61 is rotatably connected to the mounting base 2, and the movable end of the linear drive component 61 is rotatably connected to the end of the first connecting rod 4 away from the first rotating shaft 3. By driving the movable end of the linear drive component 61 to extend or retract, the functional requirement of driving the first connecting rod 4 to rotate upwards or downwards around the axis of the first rotating shaft 3 can be achieved. The structure is simple, and the drive method is stable and reliable.

[0035] Reference Figure 1-2The clamping mechanism 7 includes a fixed plate 71, a baffle 72, a second slide rail 73, a sliding seat 74, an electric telescopic rod 75, and a pneumatic gripper 76. The fixed plate 71 is bolted to the second connecting rod 5. The second slide rail 73 is fixedly mounted on the fixed plate 71. The sliding seat 74 is slidably connected to the second slide rail 73 in a direction perpendicular to the axis of the first rotating shaft 3. A baffle 72 is provided on the side of the fixed plate 71 near the first rotating shaft 3. The fixed end of the electric telescopic rod 75 is fixedly mounted on the sliding seat 74, and the movable end of the electric telescopic rod 75 is fixedly connected to the baffle 72. The extension direction of the electric telescopic rod 75 is consistent with the movement direction of the sliding seat 74. The pneumatic gripper 76 is fixedly mounted on the sliding seat 74, and the clamping part of the pneumatic gripper 76 faces the side away from the first rotating shaft 3. An extension chuck is detachably connected to the clamping part of the pneumatic gripper 76.

[0036] By activating the pneumatic gripper 76, the two clamping parts move closer or further apart, thereby causing the two extension clamps to move closer or further apart, thus clamping and releasing the log. The clamping method is simple and reliable. The detachable connection of the extension clamps allows for clamping logs of different sizes and shapes by replacing the extension clamps. The cooperation between the sliding seat 74 and the electric telescopic rod 75 makes the position of the pneumatic gripper 76 relative to the fixed plate 71 adjustable, enabling the pneumatic gripper 76 to clamp logs at different positions at the same height, improving the flexibility and adaptability of the handling device.

[0037] The implementation principle of the civil engineering heavy object loading and unloading device in this embodiment is as follows: During use, the electric telescopic rod 75 is activated, causing the pneumatic gripper 76 on the sliding seat 74 to approach the log. Then, the pneumatic gripper 76 is activated again, causing the two extended clamps to move closer together and clamp the log. Next, the movable end of the linear drive component 61 is driven to retract, causing the first connecting rod 4 to rotate downwards along the first rotating shaft 3. This causes the log inside the clamping mechanism 7 on the second connecting rod 5 to flip, thus achieving log handling. Compared to manual handling, this reduces the labor intensity of workers and increases handling efficiency. Compared to using forklifts or cranes, it reduces space limitations, making it more flexible and improving the high handling cost of logs during loading and unloading. Furthermore, rotating the screw moves the slider, causing the third connecting rod to swing, thus adjusting the angle of the mounting base 2 and consequently the height of the clamping mechanism 7 on the mounting base 2, adapting to the loading and unloading needs of logs at different heights.

[0038] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
