[0004] To solve the above-mentioned technical problems, this utility model provides a height-adjustable double-layer orthogonal conveying trolley. The conveyor frame includes a base frame, four sets of side guard frames fixedly installed on the sides of the base frame, and a top frame fixedly installed on the top of the side guard frames. The base frame has a traveling mechanism for driving movement installed at both ends. A conveying mechanism for conveying materials and a bottom transmission mechanism for driving the conveying mechanism are fixedly installed on the base frame between the traveling mechanisms. A top transmission mechanism is installed at the top of the conveying mechanism, and the top transmission mechanism is raised and lowered by a lifting mechanism fixedly installed on the top of the top frame and the sides of the side guard frames. The lifting mechanism includes a lifting reducer fixedly installed on the top of the top frame, a lifting sprocket group driven by the lifting reducer, and a chain connecting block fixedly installed on the lifting sprocket group. The four corners of the top transmission mechanism are fixedly installed to the chain connecting block through lifting frames.

[0005] As a further preferred technical solution of this utility model; an installation frame is fixedly installed on the side protective frame, and docking bearing seats for connecting and installing with the lifting sprocket group are fixedly installed on the side of the base frame at the corresponding positions of the top and bottom of the installation frame. The lifting mechanism also includes two sets of transverse transmission shafts fixedly connected to the output end of the lifting reducer, a longitudinal transmission shaft fixedly installed between the two sets of lifting sprocket groups, and an orthogonal bevel gear set that meshes with each other at the vertical position of the longitudinal transmission shaft and the transverse transmission shaft. The longitudinal transmission shaft connected to the orthogonal bevel gear set is fixedly installed on the top frame through a fixed bearing. The output end of the lifting reducer and the outside of the orthogonal bevel gear set are both provided with a top protective frame fixedly installed on the top frame.

[0006] The horizontal transmission shaft is driven to rotate by the lifting reducer, which in turn drives the vertical transmission shaft to rotate under the action of the orthogonal bevel gear set. This drives the lifting sprocket set, thereby ensuring that the lifting frame, which is fixedly installed with the lifting sprocket set, can be raised and lowered. The height of the top layer transmission mechanism can be adjusted according to the size of the material, and the material can also be lifted.

[0007] As a further preferred technical solution of this utility model; the top-level transmission mechanism includes a fixed frame fixedly installed with the lifting frame, meshing wheels installed at both ends of the fixed frame, two sets of transmission plate meshing chains meshing between the two sets of meshing wheels, a C-mounting plate fixedly installed on the fixed frame, and a transmission reducer fixedly installed on the C-mounting plate. The meshing wheels are all installed to the fixed frame through B bearing seats. A B transmission shaft is connected and installed between the meshing wheels. A transmission sprocket set is connected to the output end of the transmission reducer, and the transmission sprocket set is fixedly installed to the other end of the B transmission shaft. A limit frame is fixedly installed at the position of the meshing wheel at one end of the fixed frame, and a limit rod limits the meshing wheel to the limit frame.

[0008] The transmission reducer drives the transmission sprocket assembly to rotate the B transmission shaft, which in turn drives the meshing wheel to rotate, causing the transmission plate meshing chain that meshes with the meshing wheel to rotate, thereby achieving the conveying of materials.

[0009] As a further preferred technical solution of this utility model; positioning frames are fixedly installed on both sides of the base frame, and the conveying mechanism includes a support frame fixedly installed in the middle of the base frame, multiple sets of long rollers connected and installed with the positioning frames, and multiple sets of short rollers respectively connected and installed with the positioning frames and the support frames, and connecting bearings are fixedly installed at both ends of the short rollers.

[0010] The material is placed on top of the long rollers and the short rollers for conveying.

[0011] As a further preferred technical solution of this utility model; the bottom transmission mechanism includes a double gear coupling installed at both ends of the long roller and one end of the short roller respectively, a transmission chain connecting the double gear coupling, and a conveyor reducer for driving the double gear coupling. A B mounting plate is fixedly installed on the top of the base frame, and the conveyor reducer is fixedly installed on the top of the B mounting plate, and its output end is fixedly connected to a set of the double gear couplings.

[0012] The short and long rollers are driven by the fixed connection between the output end of the conveyor reducer and the double gear coupling, so as to achieve the function of bottom conveying of the equipment.

[0013] As a further preferred technical solution of this utility model, the walking mechanism includes walking wheels installed at the four corners of the base frame, wheel frames fixedly installed on the base frame at the top of the walking wheels, an A mounting plate fixedly installed at one corner of the base frame, and a walking reducer fixedly installed on the top of the A mounting plate. The walking wheels and the base frame are fixedly installed through A bearing seats. An A drive shaft is connected and installed between the walking wheels at one end of the base frame. An A drive sprocket is fixedly installed at the output end of the walking reducer, and the A drive sprocket is fixedly installed with the A drive shaft.

[0014] The A drive shaft is driven by a travel reducer to rotate, which in turn drives the two sets of travel wheels to rotate, thus achieving the travel effect of the equipment.

[0015] As a further preferred technical solution of this utility model, anti-collision bars are fixedly installed at both ends of the base frame.

[0016] Ensure the equipment's anti-collision performance.

[0017] Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The horizontal transmission shaft is driven to rotate by the lifting reducer, which in turn drives the vertical transmission shaft to rotate under the action of the orthogonal bevel gear set. This drives the lifting sprocket set, thereby ensuring the lifting frame, which is fixedly installed with the lifting sprocket set, can be raised and lowered. The height of the top transmission mechanism can be adjusted according to the size of the material, and the material can also be lifted. This achieves orthogonal conveying of materials in both horizontal and vertical directions. The precise transmission mechanism and control system ensure the accuracy and stability of the material when changing the conveying direction.

[0020] 2. The transmission reducer drives the transmission sprocket assembly, which in turn rotates the B transmission shaft, thereby driving the meshing wheel to rotate the transmission plate chain meshing with the meshing wheel, thus achieving material conveying. The double-layer conveying system ensures that the two layers can operate independently without interference, while also guaranteeing structural stability and reliability. Employing a unique double-layer orthogonal structure design, it offers significant advantages in space utilization and conveying flexibility compared to traditional equipment. Integrating orthogonal material conveying, double-layer conveying, and lifting functions into one unit, it achieves efficient material conveying between different directions and heights, reducing the equipment's footprint and investment costs.

Detailed Implementation

[0026] This specific embodiment is a height-adjustable double-layer orthogonal conveying trolley.

[0027] The above-mentioned utility model is a single-layer conveying trolley, which has certain functional limitations, poor space utilization, and general conveying flexibility. It cannot adjust the height of materials or convey them longitudinally. During the material conveying process, it needs to cooperate with other conveying equipment to achieve multi-directional material conveying.

[0028] Example 1: Its structural schematic diagram is as follows Figures 1-4 As shown. A height-adjustable double-layer orthogonal conveying trolley, the conveyor frame 1 includes a base frame 13, four sets of side guard frames 11 fixedly installed on the sides of the base frame 13, and a top frame 12 fixedly installed on the top of the side guard frames 11. The base frame 13 has a traveling mechanism 2 for driving movement installed at both ends. The base frame 13 between the traveling mechanisms 2 has a conveying mechanism 4 for conveying materials and a bottom transmission mechanism 3 for driving the conveying mechanism 4. The top transmission mechanism 5 is installed at the top of the conveying mechanism 4, and the top transmission mechanism 5 is lifted and lowered by a lifting mechanism 6 fixedly installed on the top of the top frame 12 and the sides of the side guard frames 11. The lifting mechanism 6 includes a lifting reducer 61 fixedly installed on the top of the top frame 12, a lifting sprocket group 64 driven by the lifting reducer 61, and a chain connecting block 65 fixedly installed on the lifting sprocket group 64. The four corners of the top transmission mechanism 5 are fixedly installed on the sides by lifting frames 14 and chain connecting blocks 65.

[0029] A mounting frame 111 is fixedly installed on the side guard frame 11. The mounting frame 111 has a docking bearing seat 66 fixedly installed on the side of the base frame 13 at the corresponding positions of the top and bottom ends for connecting and installing with the lifting sprocket group 64. The lifting mechanism 6 also includes two sets of transverse drive shafts 62 fixedly connected to the output end of the lifting reducer 61, a longitudinal drive shaft 633 fixedly installed between the two sets of lifting sprocket groups 64, and an orthogonal bevel gear group 63 that meshes with each other at the vertical position of the longitudinal drive shaft 633 and the transverse drive shaft 62. The longitudinal drive shaft 633 connected to the orthogonal bevel gear group 63 is fixedly installed on the top frame 12 through a fixed bearing 631. The output end of the lifting reducer 61 and the outside of the orthogonal bevel gear group 63 are both provided with a top guard frame 632 fixedly installed on the top frame 12. The horizontal transmission shaft 62 is driven to rotate by the lifting reducer 61, which in turn drives the vertical transmission shaft 633 to rotate under the action of the orthogonal bevel gear set 63. This causes the lifting sprocket set 64 to perform transmission, thereby ensuring that the lifting frame 14, which is fixedly installed with the lifting sprocket set 64, can be raised and lowered. The height of the top layer transmission mechanism 5 can be adjusted according to the size of the material, and the material can also be lifted. This achieves orthogonal conveying of materials in both horizontal and vertical directions. The precise transmission mechanism and control system ensure the accuracy and stability of the material when changing the conveying direction. Load capacity: 5 tons.

[0030] The top-level transmission mechanism 5 includes a fixed frame 15 fixedly installed with the lifting frame 14, meshing wheels 54 installed at both ends of the fixed frame 15, two sets of transmission plate meshing chains 53 meshing between the two sets of meshing wheels 54, a C mounting plate 511 fixedly installed on the fixed frame 15, and a transmission reducer 51 fixedly installed on the C mounting plate 511. The meshing wheels 54 are all installed with the fixed frame 15 through B bearing seats 55. A B transmission shaft 56 is connected between the meshing wheels 54. A transmission sprocket set 52 is installed at the output end of the transmission reducer 51, and the transmission sprocket set 52 is fixedly installed with the other end of the B transmission shaft 56. A limit frame 57 is fixedly installed at the position of the meshing wheel 54 at one end of the fixed frame 15. The limit rod 541 limits the meshing wheel 54 to the limit frame 57. The transmission reducer 51 drives the transmission sprocket group 52, which in turn drives the B transmission shaft 56 to rotate. This, in turn, drives the meshing wheel 54, causing the transmission plate meshing chain 53, which meshes with the meshing wheel 54, to rotate, thus achieving material conveying. The conveying speed is 26 m / min. The double-layer conveying system ensures that the two layers can operate independently without interference, while also guaranteeing structural stability and reliability. It adopts a unique double-layer orthogonal structure design, which offers significant advantages in space utilization and conveying flexibility compared to traditional equipment. Integrating orthogonal material conveying, double-layer conveying, and lifting functions, it achieves efficient material conveying between different directions and heights, reducing the equipment's footprint and investment costs.

Connecting bearings are fixedly installed at both ends of the short rollers 42. The material is placed on top of the long rollers 41 and the short rollers 42 for conveying. The bottom transmission mechanism 3 includes double gear couplings 34 respectively installed at both ends of the long rollers 41 and one end of the short rollers 42, a transmission chain 33 connecting the double gear couplings 34, and a conveying reducer 31 for driving the double gear couplings 34.

The conveying reducer 31 is fixedly installed on the top of the B mounting plate 35, and its output end is fixedly connected to a set of double gear couplings 34. The short roller 42 and long roller 41 are driven by the fixed connection between the output end of the conveyor reducer 31 and the double gear coupling 34 to achieve the bottom conveying function of the equipment. The roller conveying speed is 23 m / min. Through the double-layer structure design, materials can be conveyed to two layers within the same floor area. Compared with single-layer equipment, this greatly improves space utilization and better adapts to production workshops with limited space. It also meets the conveying needs of different conveying directions, facilitating material transition and connection at production line intersections, making the workshop production line layout more flexible and rational, and improving production efficiency. It enables the classified and layered conveying of various materials. According to the needs of different workstations, materials of different types or processing stages can be placed on the upper and lower layers for conveying, improving the flexibility and targeting of the conveying process.

An A-drive sprocket 23 is fixedly installed at the output end of the traveling reducer 22, and the A-drive sprocket 23 is fixedly installed to the A-drive shaft 25. The traveling reducer 22 drives the A-drive shaft 25 to rotate, thereby driving the two sets of traveling wheels 26 to rotate, achieving the traveling effect of the equipment. The equipment is equipped with an advanced intelligent control system, realizing automated operation, automatic material identification and positioning, automatic fault diagnosis and alarm functions, improving the automation level of production and the reliability of the equipment, and reducing labor costs and labor intensity. Anti-collision bars 131 are fixedly installed at both ends of the base frame 13 to ensure the anti-collision effect of the equipment.

[0033] The output end of the conveyor reducer 31 is fixedly connected to the double gear coupling 34 to drive the short roller 42 and the long roller 41, thereby achieving the bottom conveying function of the equipment. The transmission reducer 51 drives the transmission sprocket group 52 to drive the B transmission shaft 56 to rotate, thereby driving the meshing wheel 54 to rotate, so that the transmission plate meshing chain 53 meshing with the meshing wheel 54 rotates to achieve the conveying of materials. The double-layer conveying ensures that the two layers of conveying can operate independently and without interference, while ensuring the stability and reliability of the structure. It adopts a unique double-layer orthogonal structure design, which has significant advantages in space utilization and conveying flexibility compared with traditional equipment. The horizontal transmission shaft 62 is driven to rotate by the lifting reducer 61, which in turn drives the vertical transmission shaft 633 to rotate under the action of the orthogonal bevel gear set 63. This causes the lifting sprocket set 64 to perform transmission, thereby ensuring that the lifting frame 14, which is fixedly installed with the lifting sprocket set 64, can be raised and lowered. The height of the top layer transmission mechanism 5 can be adjusted according to the size of the material, and the material can also be lifted, realizing orthogonal conveying of the material in the horizontal and vertical directions.
