Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying devices, in particular to a material conveying device for an intelligent truss production line. BACKGROUND

[0002] A truss is a geometrically stable structure system formed by straight rods connected through nodes, commonly used in large-span structures such as bridges and building roofs. Among them, the triangular truss is widely used due to its excellent stability and high material utilization rate, and its basic unit is a triangle, which forms a whole force structure by repeated combination of multiple triangles. Under the background of modern intelligent manufacturing, intelligent truss production lines are gradually popularized, and higher requirements are put forward for the automation and high-precision logistics conveying of truss components. At present, some production lines use automatic transport vehicles to run along fixed tracks or autonomous navigation paths to realize continuous and efficient material flow between the material preparation area, processing stations and assembly stations.

[0003] However, in the intelligent truss production line, different specifications of triangular truss section members have the characteristics of various sizes, and the existing material conveying devices have poor adaptability and cannot effectively accommodate truss structures of different sizes, resulting in poor fixation, which can cause the truss to loosen, shift or even fall off during transfer, and may also cause harm to the operator during movement, therefore improvement is urgently needed.

[0057] Reference Figures 1 to 7An embodiment of the material transport device for an intelligent truss production line according to the present invention will be further described.

[0058] A material handling device for an intelligent truss production line includes a transport platform 1, and further includes:

[0059] Four rotating platforms 2 are provided, and the four rotating platforms 2 are fixedly installed on the transport platform 1; they are used to limit the position of the rollers 3.

[0060] There are four rollers 3, which are rotatably mounted on the rotating platform 2; used for the movement of the entire device.

[0061] Reference Figures 2 to 4 In a preferred embodiment, there are two cross sliding tables 4, which are symmetrically arranged on the transport table 1 and slidably connected to the transport table 1.

[0062] A cross-shaped sliding groove 11 is provided on the transport table 1 to limit and guide the movement path of the cross-shaped sliding table 4.

[0063] A rotating mechanism, mounted on the transport table 1, is used to move the two cross-shaped sliding tables 4 closer together or further apart; the rotating mechanism includes:

[0064] The first motor 8 is fixedly mounted on the transport platform 1;

[0065] A bidirectional lead screw 9 is rotatably mounted on the transport table 1, and one end of the bidirectional lead screw 9 is fixedly connected to the output end of the first motor 8.

[0066] There are two built-in threaded sleeves 10, which are symmetrically arranged on the bidirectional lead screw 9 and threadedly connected to the bidirectional lead screw 9. The built-in threaded sleeves 10 are fixedly connected to the cross sliding table 4.

[0067] There are four T-shaped fixing plates 5, and the four T-shaped fixing brackets are fixedly installed on the cross sliding table 4.

[0068] During operation, the first motor 8 is started, which drives the bidirectional lead screw 9, which is fixedly connected to its output end, to rotate. The bidirectional lead screw 9 drives the two built-in threaded sleeves 10 to move closer or further apart. The two built-in threaded sleeves 10 drive the two cross sliding tables 4 to move closer or further apart along the cross sliding groove 11. The cross sliding tables 4 drive the two support tables 6 to move closer or further apart through the T-shaped fixing plate. The support tables 6 drive the drive mechanism, the fixed triangle plate 7, and the fixing mechanism to move, thereby achieving precise adjustment of the relative distance between the two triangular truss sections. This allows for adaptation to truss structures of different sizes, achieving stable support and positioning for trusses of various specifications, and improving the versatility of the equipment.

[0069] Reference Figure 3 and Figure 4In a preferred embodiment, the support platform 6 is provided with four T-shaped limiting grooves 14, which are used to provide compression space for the shock absorption mechanism and to guide and restrict the movement trajectory of the T-shaped fixing plate 5.

[0070] The shock absorption mechanism comprises eight components, which are mounted on the T-shaped fixed plate 5 to absorb vibration energy generated during movement. The shock absorption mechanism includes:

[0071] Eight shock absorbers 12 are provided. The eight shock absorbers 12 are fixedly installed on the support platform 6 and fixedly connected to the T-shaped fixing plate 5.

[0072] There are eight reset springs 13, which are set on the support platform 6. One end of the reset spring 13 is fixedly connected to the support platform 6, and the other end of the reset spring 13 is fixedly connected to the T-shaped fixing plate 5.

[0073] During operation, the vibration generated during the movement causes the support platform 6 to move upward, thereby causing the T-shaped fixing plate to move downward along the T-shaped limiting groove. The T-shaped fixing plate compresses the return spring 13 and stores its elastic potential energy. The damping device 12 absorbs the vibration energy and converts it into heat energy. At this time, the return spring 13 releases its elastic potential energy, causing the support platform 6 to move downward, thus stabilizing the device.

[0074] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, there are two support platforms 6, which are mounted on the shock-absorbing mechanism and slidably connected to the T-shaped fixing plate 5.

[0075] The support platform 6 has two operating spaces 21 to provide space for the rotation of the drive mechanism; the support platform 6 has six cross-shaped moving grooves 22 to limit the movement trajectory of the cross-shaped moving key 19.

[0076] There are two drive mechanisms, which are mounted on the support platform 6; the drive mechanisms include:

[0077] Two second motors 15 are provided, and the two second motors 15 are fixedly mounted on the support platform 6.

[0078] Two rotating rods 16 are provided, and the two rotating rods 16 are mounted on the second motor 15. One end of the rotating rod 16 is fixedly connected to the output end of the second motor 15.

[0079] There are two rotating discs 17, and the two rotating discs 17 are fixedly mounted on the rotating rod 16;

[0080] There are six arc-shaped grooves 18, which are formed on the rotating disk 17.

[0081] There are six movable components, which are mounted on the support platform 6. The movable components include:

[0082] Six cross-shaped movement keys 19 are provided. The six cross-shaped movement keys 19 are slidably set on the support platform 6 and are fixedly connected to the fixed triangle plate 7.

[0083] There are six drive cylinders 20, which are fixedly mounted on the cross-shaped moving key 19 and slidably connected to the rotating disk 17.

[0084] There are six fixed triangular plates 7, which are set on the drive mechanism to stabilize and fix triangular truss sections of different sizes.

[0085] During operation, the second motor 15 is started, which drives the rotating rod 16, which is fixedly connected to its output end, to rotate. The rotating rod 16 drives the rotating disk 17 to rotate, which is used to limit the cross-shaped moving groove 22, so that the driving cylinder 20, which is fixedly connected to the cross-shaped moving key 19, can only move along the cross-shaped moving groove 22. The rotating disk 17 drives the three driving cylinders 20 to move along the arc-shaped groove 18 and the cross-shaped moving groove 22. The driving cylinders 20 drive the three fixed triangular plates 7 to move in a triangular expansion or contraction motion in the plane through the cross-shaped moving key 19, thereby adapting to triangular truss sections of different sizes, completing the reliable clamping and positioning of various triangular truss sections, and improving the adaptability of the equipment.

[0086] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, the fixed triangular plate 7 is provided with six limiting lifting grooves 26 to limit the lifting trajectory of the vertical fixed plate 25.

[0087] There are six fixing mechanisms, which are mounted on the fixing triangle 7. The fixing mechanisms include:

[0088] There are six third motors 23, which are fixedly mounted on the fixed triangular plate 7.

[0089] There are six screws 24, which are rotatably mounted on the fixed triangular plate 7. One end of each screw 24 is fixedly connected to the output end of the third motor 23.

[0090] There are six vertical fixing plates 25, which are threaded onto the screw 24 and slidably connected to the fixing triangle plate 7.

[0091] During operation, the third motor 23 is started, which drives the screw 24 fixedly connected to its output end to rotate. The screw 24 drives the vertical fixing plate 25 to move up and down along the limit lifting groove 26. The vertical fixing plate 25 is used to cooperate with the support platform 6 to achieve vertical fixation of the truss and prevent damage to the truss due to bumps during movement.

[0092] Working principle: Based on the distance between the two triangular truss sections, the first motor 8 is activated. The first motor 8 drives the bidirectional lead screw 9 to rotate. The bidirectional lead screw 9 drives the two internal threaded sleeves 10 to move closer or further apart. The two internal threaded sleeves 10 drive the two cross sliding tables 4 to move closer or further apart along the cross sliding groove 11. The cross sliding tables 4, through the T-shaped fixing plate, drive the two support platforms 6 to move closer or further apart. The support platforms 6 drive the drive mechanism, the fixed triangular plate 7, and the fixing mechanism to move, thus adapting to truss structures of different sizes. Subsequently, the second motor 15 is activated. The second motor 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the rotating disk 17 to rotate. Due to the limitation of the cross moving groove 22, the driving cylinder 20, fixedly connected to the cross moving key 19, can only move along the cross moving groove 22. The rotating disk 17, through the arc groove 18, drives the three driving cylinders 20 to move along the cross moving groove 22. The column 20 drives three fixed triangular plates 7 to expand or contract in a triangular shape within a plane via the cross-shaped moving key 19, thereby adapting to triangular truss sections of different sizes and completing the reliable clamping and positioning of various triangular truss sections. Finally, the third motor 23 is started, which drives the screw 24 to rotate. The screw 24 drives the vertical fixing plate 25 to move up and down along the limiting lifting groove 26. The vertical fixing plate 25 is used to cooperate with the support platform 6 to achieve vertical fixation of the truss. The vibration generated during the movement drives the support platform 6 to move upward, thereby causing the T-shaped fixing plate to move downward along the T-shaped limiting groove. The T-shaped fixing plate compresses the return spring 13 and stores its elastic potential energy. The damping damper 12 absorbs the vibration energy and converts it into heat energy. At this time, the return spring 13 releases its elastic potential energy, driving the support platform 6 to move downward, making the device more stable and preventing damage to the truss due to bumps during the movement.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
