Description

Technical Field

[0001] This utility model relates to the field of mechanical handling equipment technology, specifically providing an adjustable heavy workpiece installation and positioning handling vehicle. Background Technology

[0002] In large-scale industrial manufacturing, energy equipment, heavy machinery, and building structures, the installation of massive workpieces is a crucial step in engineering construction. Traditional installation methods typically rely on temporary lifting equipment such as gantry cranes, tower cranes, and hydraulic lifting devices, requiring multiple adjustments to hoist the workpiece to the designated location. However, this method suffers from numerous technical drawbacks, severely impacting construction efficiency and safety.

[0003] First, the setup of lifting equipment is complex and inefficient. Before lifting operations, significant manpower and resources are required for foundation preparation, support structure assembly, equipment debugging, and load testing. For single or non-repetitive lifting tasks, the setup and dismantling time of temporary equipment may even exceed the actual lifting operation time, leading to a substantial extension of the project cycle and a significant increase in costs. Furthermore, limited space or insufficient foundation bearing capacity at some construction sites further complicates the deployment of lifting equipment.

[0004] Secondly, the workpiece hoisting process suffers from poor stability and significant safety hazards. Large workpieces are susceptible to severe swaying or deflection during hoisting, moving, and positioning due to factors such as wind, inertia, and wire rope swaying. This not only increases the difficulty of precise alignment but may also cause collisions between the workpiece and surrounding structures, potentially leading to equipment damage or personal injury. The swaying problem is particularly pronounced in confined spaces or high-altitude operations, making traditional methods relying on manual experience insufficient for high-precision installation requirements.

[0005] Furthermore, traditional methods rely on manual operation, resulting in insufficient controllability. The hoisting process typically requires multiple operators to work together, adjusting the workpiece's posture visually or using simple measuring tools. The accuracy and efficiency are significantly affected by the operators' skill levels. Under complex conditions (such as nighttime construction or inclement weather), the risk of human error increases further, making it difficult to guarantee consistent installation quality.

[0006] In summary, existing technologies for installing large-mass workpieces have inherent drawbacks such as cumbersome processes, low efficiency, and high safety risks, and there is an urgent need for a simple and stable handling device. Utility Model Content

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0033] The following is combined Figures 1 to 7 The technical solution of this utility model is described as follows: This utility model provides an adjustable heavy-duty workpiece installation and positioning transport vehicle, including: a tracked walking mechanism 100 and a turntable assembly 200 mounted thereon; a horizontal lifting mechanism 300 disposed on the surface of the turntable assembly 200, the turntable assembly 200 driving the horizontal lifting mechanism 300 to rotate on the tracked walking mechanism 100; and a workpiece fixing mechanism 400 disposed at the top end of the horizontal lifting mechanism 300; wherein the horizontal lifting mechanism 300 is used to adjust the horizontal distance between the workpiece fixing mechanism 400 and the turntable assembly 200.

[0034] In the above embodiments, when installing heavy workpieces, the workpiece is fixed on the workpiece fixing mechanism 400. Then, the crawler walking mechanism 100 is started to transport the workpiece over a short distance. When the workpiece reaches the installation position, the horizontal lifting mechanism 300 is started, which then lifts the workpiece fixing mechanism 400, allowing the workpiece fixing mechanism 400 to adjust the vertical height of the workpiece. Then, the turntable assembly 200 is started, which drives the horizontal lifting mechanism 300 and the workpiece fixing mechanism 400 to rotate, causing the turntable assembly 200 to rotate the workpiece fixing mechanism 400 and the workpiece around the Z-axis. The crawler walking mechanism 100 is started again to move the workpiece closer to the installation position, and then the workpiece is installed at the installation position. This improves the problem of low operation efficiency when traditionally installing large-mass workpieces, which requires the use of gantry cranes for hoisting. It also reduces the problem of workpiece swaying during positioning and installation, solves the problems of inconvenient installation and cumbersome operation of gantry cranes, and improves the efficiency of heavy workpiece installation.

[0035] Please see Figures 1-7 In some embodiments, the tracked walking mechanism 100 includes: a frame 110 disposed below the turntable assembly 200, a horizontal mounting platform 120 disposed at the center of the frame 110, and the turntable assembly 200 disposed on the surface of the horizontal mounting platform 120; a track assembly 130 mounted on both sides of the frame 110; and a servo motor assembly 140 connected to the track assembly 130 in a transmission manner.

[0036] In the above embodiment, the upper part of the frame 110 is used to install the turntable assembly 200, and the track assembly 130 is symmetrically installed on both sides of the frame 110 to provide walking power. The servo motor group 140 controls the tracks on both sides to rotate synchronously in the same direction (such as both forward or backward), so that the frame 110 moves in a straight line. The servo motor group 140 can also adjust the speed difference of the tracks on both sides to realize the turning of the frame 110 around the center point. Compared with the roller design, the track assembly 130 can achieve flexible turning effect, stable load bearing, and avoid the phenomenon of large swing and overturning of heavy workpieces during the movement of the track walking mechanism 100.

[0037] Please see Figures 1-7 In some embodiments, the turntable assembly 200 includes: a positioning post 210 disposed at the upper center of the tracked walking mechanism 100; a worm gear 220 horizontally sleeved on the circumferential outer wall of the positioning post 210; a worm 230 disposed on one side of the worm gear 220, the worm 230 meshing with the worm gear 220; a servo motor 240 mounted on the surface of the tracked walking mechanism 100, the output shaft of the servo motor 240 connected to one end of the worm 230; and a mounting plate 250 disposed on the surface of the worm gear 220.

[0038] In the above embodiment, when the turntable assembly 200 is working, the servo motor 240 starts, and its output shaft rotates, driving the worm gear 230 to rotate around the axis of the output shaft of the servo motor 240. During the rotation of the worm gear 230, since it meshes with the worm wheel 220, it can drive the worm wheel 220 to rotate around the axis of the positioning column 210. During the rotation of the worm wheel 220 around the outer wall of the positioning column 210, it drives the mounting plate 250 installed on the top surface of the worm wheel 220 to rotate. The surface of the mounting plate 250 is used to install the horizontal lifting mechanism 300. Then, the mounting plate 250 drives the horizontal lifting mechanism 300 and the workpiece fixing mechanism 400 to rotate around the axis of the positioning column 210.

[0039] Please see Figures 1-7 In some embodiments, the turntable assembly 200 further includes: multiple push rods 260, the lower ends of the multiple push rods 260 are arranged in a ring array on the surface of the track walking mechanism 100, and the top ends of each push rod 260 slide on the bottom surface of the mounting plate 250.

[0040] In the above embodiment, multiple push rods 260 are arranged in a ring between the horizontal mounting platform 120 and the mounting plate 250 to support the bottom surface of the mounting plate 250 near the edge, so as to prevent the edge of the mounting plate 250 from being suspended. When the turntable assembly 200 drives the workpiece to rotate around the positioning column 210, the center of gravity of the heavy workpiece is not collinear with the straight line where the positioning column 210 is located, which causes the mounting plate 250 to be subjected to excessive force on one side, resulting in the overturning phenomenon. It is worth noting that the top of the push rod 260 slides and rubs against the bottom surface of the mounting plate 250. Alternatively, a caster wheel can be installed on the top of the push rod 260 so that the push rod 260 rolls and rubs against the mounting plate 250 through the caster wheel, thereby reducing the friction loss at the top of the push rod 260.

[0041] Please see Figures 1-7 In some embodiments, the horizontal lifting mechanism 300 includes: a guide rail mechanism 310, provided in two sets, the two sets of guide rail mechanisms 310 being spaced apart on the surface of the mounting plate 250; wherein the guide rail mechanism 310 is vertically arranged, and the end wall of the workpiece fixing mechanism 400 is slidably mounted on the guide rail mechanism 310; and an electric telescopic assembly 320, one end of which is hinged to the surface of the mounting plate 250, and the other end of which is hinged to the bottom surface of the workpiece fixing mechanism 400.

[0042] In the above embodiments, when the workpiece fixing mechanism 400 needs to be lifted by the horizontal lifting mechanism 300, the electric telescopic component 320 is activated so that its top extension pushes the bottom surface of the workpiece fixing mechanism 400 upward. During the upward movement of the workpiece fixing mechanism 400, the end wall of one end slides on the guide rail mechanism 310. The mounting end of the electric telescopic component 320 is set close to the guide rail mechanism 310, and the top extension is set away from the guide rail mechanism 310.

[0043] Please see Figures 1-7 In some embodiments, the guide rail mechanism 310 includes: mounting posts 311, two mounting posts 311 spaced apart on both sides of the electric telescopic assembly 320; a slide rail 312, disposed on the side of the mounting posts 311 near the workpiece fixing mechanism 400; and two sets of sliders 313, the two sets of sliders 313 spaced apart on the end wall of the workpiece fixing mechanism 400; wherein the side of the slider 313 away from the workpiece fixing mechanism 400 is slidably disposed on the slide rail 312.

[0044] In the above embodiments, the thrust direction of the electric telescopic component 320 may generate a lateral component due to installation errors or uneven load. The slide rail 312 can constrain the platform to move only in the vertical direction, avoiding tilting or jamming. At the same time, during the lifting process of the workpiece fixing mechanism 400, the guiding effect of the slide rail 312 can ensure the straightness of the lifting of the workpiece fixing mechanism 400 and improve the repeatability of positioning accuracy. The slide rail 312 can absorb radial force, protect the internal transmission components of the electric telescopic component 320, and share the friction load.

[0045] Please see Figures 1-7 In some embodiments, the electrically telescopic assembly 320 includes: a first mounting base 321 and a second mounting base 322, spaced apart on the surface of the mounting plate 250, wherein the line connecting the first mounting base 321 and the second mounting base 322 is perpendicular to the line connecting the two sets of mounting posts 311; a servo electric cylinder 323, the mounting end of which is hinged to the first mounting base 321; a first fixing rod 324, located at the extended end of the servo electric cylinder 323, wherein the axis of the first fixing rod 324 is perpendicular to the axis of the extended end of the servo electric cylinder 323; and two sets of V-bars 325. 5 are respectively disposed at both ends of the first fixing rod 324; wherein one end sidewall of the V rod 325 is hinged to the end wall of the first fixing rod 324; the second fixing rod 326 is provided in two sets, one end of the two sets of the second fixing rod 326 is respectively connected to the sidewall of the two sets of V rods 325 away from the first fixing rod 324, and the two sets of the second fixing rods 326 are disposed on the side of the V rod 325 away from the first fixing rod 324; the second fixing rod 326 slides horizontally along the bottom surface of the workpiece fixing mechanism 400; the corner of the V rod 325 is hinged to the second mounting base 322.

[0046] In the above embodiments, the first mounting base 321 and the second mounting base 322 are respectively used to mount the servo electric cylinder 323 and the V-rod 325. When the workpiece fixing mechanism 400 is lifted, the servo electric cylinder 323 is activated so that its extended end pushes the first fixed rod 324 to move. The distance between the first fixed rod 324 and the first mounting base 321 increases. The two ends of the first fixed rod 324 drive the two ends of the two sets of V-rods 325 to swing around the second mounting base 322. This causes the end of the V-rod 325 away from the first fixed rod 324 to drive the second fixed rod 326 to swing around the second mounting base 322. During the swing of the second fixed rod 326, the height gradually increases. When the second fixed rod 326 slides on the bottom surface of the workpiece fixing mechanism 400, it pushes the workpiece fixing mechanism 400 to rise. The V-rod 325 is located below the workpiece on the workpiece fixing mechanism 400. The V-rod 325 can save more effort during the pushing process of the servo electric cylinder 323 through the lever principle, thereby improving the load capacity of the servo electric cylinder 323. At the same time, the setting of the V-rod 325 saves more installation space compared with the traditional lever.

[0047] Please see Figures 1-7 In some embodiments, the workpiece fixing mechanism 400 includes: a U-shaped bracket 410 disposed on the upper part of the horizontal lifting mechanism 300; two sets of upright plates 420, which are spaced apart on the bottom surface of the U-shaped bracket 410, with the slider 313 mounted on one end of each upright plate 420; and a strip-shaped hole 430 disposed on the surface of the upright plate 420, which is horizontally arranged, with one end of the second fixing rod 326 slidably disposed within the strip-shaped hole 430. The system includes two sets of anti-slip grippers 440, each located on the inner wall of one end of the U-shaped base 410; adjustment holes 450, vertically located on the outer wall of both ends of the U-shaped base 410; adjustment bolts 460, one end of which passes through the adjustment holes 450 and is threadedly connected to the anti-slip grippers 440; and two sets of positioning plates 470, each located on both sides of the adjustment holes 450, with the adjustment bolts 460 rotatably connected to the positioning plates 470.

[0048] In the above embodiment, the heavy workpiece is placed in the opening of the U-shaped bracket 410, and the adjusting bolt 460 is turned so that the threaded end of the adjusting bolt 460 gradually comes out of the threaded hole on the anti-slip gripper 440. The adjusting bolt 460 drives the positioning plate 470 to gradually approach the adjusting hole 450 until the adjusting bolt 460 is locked outside the adjusting hole 450. The adjusting bolt 460 moves up and down in the adjusting hole 450, which drives the anti-slip gripper 440 to move up and down. Then, the adjusting bolt 460 can be used to push the anti-slip gripper 440 towards the workpiece, so as to achieve the purpose of clamping the workpiece on both sides.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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 do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
