Description

Technical Field

[0001] This invention relates to the field of aircraft support equipment technology, and in particular to a high-efficiency ground assembly vehicle. Background Technology

[0002] With the increasing application of multi-unit modular equipment, the existing support equipment assembly vehicles have limited adjustment functions on the top bracket of the assembly platform. They cannot simultaneously assemble two components in a single row. Often, after the front component is assembled, the rear component cannot be adjusted. The lifting lugs of the front component need to be detached from the bracket and readjusted to complete the front-to-back assembly, which is time-consuming and labor-intensive, greatly affecting the assembly efficiency of the support equipment.

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0096] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0097] The present invention is as follows Figure 1 As shown, a high-efficiency ground-based assembly vehicle includes: a chassis running mechanism 1, a lifting platform 2, an assembly and adjustment platform 3, and a lifting interface mechanism 4.

[0098] The chassis running mechanism 1 includes a frame body 11, and the hoisting platform 2 and the assembly and adjustment platform 3 are respectively mounted on the frame body 11.

[0099] The hoisting platform 2 hoists the object through the hoisting interface mechanism 4; Figure 1 The arrows in the text represent the directions: forward, backward, left, and right.

[0100] like Figure 2-12 As shown, the assembly and adjustment platform 3 is used to adjust the posture of the object during assembly. The assembly and adjustment platform 3 includes, from bottom to top, a lifting mechanism 31, a lifting, pitching and rolling mechanism 32, a lateral shifting and rotating mechanism 33, a heading fine-tuning mechanism 34, and a single-row front-to-back and height fine-tuning structure 35.

[0101] The lifting mechanism 31 includes a lifting base 311 and an adjusting base 321. The lifting base 311 is connected to the vehicle frame body 11, and the adjusting base 321 is flexibly connected above the lifting base 311.

[0102] The lifting, pitching, and rolling mechanism 32 includes four sets of worm gear screw jacks 322, a ball joint interface 323, and a lateral rotating base 331.

[0103] The lateral rotation base 331 is located above the attitude adjustment base 321, and four sets of worm gear screw jacks 322 are respectively located at the four corners of the attitude adjustment base 321.

[0104] The worm gear screw jack 322 is used to drive the ball socket interface 323 to rise and fall, and the top of the ball socket interface 323 is connected to the lateral rotating base 331 through the connecting plate 324;

[0105] When the four sets of worm gear screw jacks 322 lift synchronously, the overall lifting of the assembly and adjustment platform is achieved; when the extension and retraction speeds of the two sets of worm gear screw jacks in front are not synchronized with the two sets of worm gear screw jacks behind, the pitch adjustment action of the assembly and adjustment platform is achieved; when the extension and retraction speeds of the two sets of worm gear screw jacks on the left are not synchronized with the two sets of worm gear screw jacks on the right, the roll adjustment action of the assembly and adjustment platform is achieved; the posture adjustment ensures that the posture of the assembly below and the hanging frame above are consistent.

[0106] The lateral rotation mechanism 33 includes two sliding plates 332, a slewing support 333, and a heading fine-tuning base 341.

[0107] Two sliding plates 332 are slidably connected to both ends of the lateral rotating base 331, and the rotary support 333 is mounted on one of the sliding plates 332.

[0108] One end of the heading fine-tuning base 341 is connected to the slewing support 333, and the other end is connected to another sliding plate 332;

[0109] The heading fine-tuning mechanism 34 includes an assembly beam base 342, which is slidably connected to the heading fine-tuning base 341.

[0110] The heading fine-tuning mechanism 34 also includes a lead screw drive assembly 343 and a nut seat 344. The lead screw drive assembly 343 is connected to the heading fine-tuning base 341. The structure of the lead screw drive assembly 343 is the same as that of the lead screw drive assembly 313. The lead screw drive assembly 343 drives the nut seat 344 connected to the assembly beam base 342.

[0111] The assembly beam base is equipped with a slider, and the heading fine-tuning base is equipped with a guide rail that matches the slider for easy guidance.

[0112] The single-row front-to-back and height fine-tuning structure 35 includes at least one row of bracket assemblies. The bracket assemblies are mounted on the heading fine-tuning base 341 and include two sets of bracket components 351 arranged front and back. The bracket components 351 are used to support the object.

[0113] One of the bracket assemblies is equipped with a front-to-back linkage fine-tuning mechanism 352, which is used to move and adjust the bracket assembly 351.

[0114] The front and rear linkage fine-tuning mechanism enables one set of bracket components to form a floating bracket component relative to the heading fine-tuning base, while the other set of bracket components is fixedly connected to the heading fine-tuning base to form a fixed bracket component.

[0115] In its operation, this invention improves upon the structural design concept of adding relative fine-tuning and height fine-tuning of a single row by setting three rows of assembly beam brackets (i.e., bracket assemblies) at the top layer of the assembly adjustment platform. Since mismatches in distance and height are inevitable when assembling two components in the same row during a single assembly, this design avoids the problem of assembly failure in a single row due to the inability to adjust the distance and height of the other component after one component is attached, effectively solving the pain points of existing assembly vehicles.

[0116] In addition, the height fine-tuning function is also used to quickly adjust the height of a single-row assembly beam bracket, so that the overall height of the assembly of one row is higher than the height of the other two rows each time, ensuring the reliability of the assembly adjustment.

[0117] The top of the assembly and adjustment platform can be adapted to accommodate various combinations of assemblies by replacing the bracket components, making it highly versatile in practical use.

[0118] To improve the overall assembly time, the lifting interface mechanism on the lifting platform has been designed to be universal, allowing for the simultaneous lifting of multiple assemblies.

[0119] This invention optimizes the process from multiple dimensions, greatly improving the efficiency of the assembly process.

[0120] like Figure 11-12 As shown, the bracket assembly 351 includes a first fine-tuning jack 3511, a second fine-tuning jack 3512, a front bracket 3513, and a rear bracket 3514, arranged at the front and rear.

[0121] The front bracket 3513 is located on top of the first fine-tuning jack 3511, and the rear bracket 3514 is located on top of the second fine-tuning jack 3512.

[0122] The bases of the fine-tuning jack 1 3511 and the fine-tuning jack 2 3512 are respectively equipped with scales 353.

[0123] The front-to-back linkage fine-tuning mechanism 352 includes a fixed base 3521, a forward and reverse threaded rod 3522, and a linkage pull rod 3523.

[0124] The fixed base 3521 is located at the front end of the heading fine-tuning base 341, and the positive and negative threaded rods 3522 are connected between the fixed base 3521 and the base of the fine-tuning jack 3511.

[0125] The linkage rod 3523 is connected between the first fine-tuning jack 3511 and the second fine-tuning jack 3512.

[0126] The fine-tuning jacks 3511 and 3512 are slidably connected to the heading fine-tuning base 341. In application, the heading fine-tuning base is equipped with a guide rail, and the bases of the fine-tuning jacks 3511 and 3512 are equipped with sliders. The sliders and guide rails cooperate to facilitate the sliding of the fine-tuning jacks 3511 and 3512.

[0127] The fine-tuning jacks 3511 and 3512 are scissor jacks, which are conventional devices operated by handwheels. The forward and reverse threaded rod 3522 is equipped with an operating handle 3524.

[0128] Due to its compact design in the width direction, the bracket components in adjacent rows of bracket assemblies are staggered in the front-to-back direction, facilitating easy operation of the height adjustment handwheels on the first and second jacks, thus meeting ergonomic requirements. During installation, the rear side is used as a fixed reference for installation, followed by the installation of the floating bracket section in the front of the same row. The single-row front-to-back relative fine-tuning and height fine-tuning mechanisms are then used to align it with the top bracket.

[0129] like Figure 3 As shown, the lifting mechanism 31 also includes a pair of parallel scissor arms 3121, a pair of parallel scissor arms 3122, a lead screw drive assembly 313, and a connecting rod 314.

[0130] The scissor arms 3121 and 3122 are cross-connected, and their ends are respectively connected to the lifting base 311 and the attitude adjustment base 321.

[0131] The lead screw drive assembly 313 includes a drive motor 3131 and a trapezoidal lead screw 3132. The drive motor 3131 is connected to the lifting base 311 and drives the trapezoidal lead screw 3132.

[0132] The inner walls on both sides of the posture adjustment base 321 are respectively provided with sliding grooves 3210, and the two ends of the connecting rod 314 pass through the bottom of the scissor arm 3122 and are slidably connected in the sliding grooves 3210.

[0133] The trapezoidal lead screw 3132 and the connecting rod 314 are connected by threads.

[0134] The drive motor 3131 drives the trapezoidal lead screw 3132 to rotate, thereby moving the connecting rod 314 back and forth. The connecting rod 314 drives the second scissor arm 3122 to move, and then the overall lifting function is achieved through the movement of the first scissor arm 3121 and the second scissor arm 3122.

[0135] like Figure 4-5 As shown, the ball joint 323 includes a ball joint 3231, an upper ball flange plate 3232, and a lower ball clamping plate 3233.

[0136] The lifting screw in the worm gear screw jack 322 is connected to a ball joint 3231, which is connected between the upper spherical flange plate 3232 and the lower spherical clamping plate 3233.

[0137] By setting up a ball socket interface, it can adapt to different fine-tuning movements (such as pitch and roll) during the lifting and lowering process.

[0138] like Figure 7-9 As shown, another slide plate 332 in the lateral rotation mechanism 33 is provided with a Teflon wear-resistant plate 334, and the other end of the heading fine-tuning base 341 is connected to the Teflon wear-resistant plate 334.

[0139] It also includes a rotating connecting block 335 and a rotating pin 336. The heading fine-tuning base 341 is provided with a connecting hole 3410, which is located above the Teflon wear-resistant plate 334.

[0140] The rotating connecting block 335 has a horizontal-folded structure. The rotating connecting block 335 includes an upper horizontal plate, a vertical plate, and a lower horizontal plate. The upper horizontal plate is located on the heading fine-tuning base 341. The vertical plate and the lower horizontal plate are located within the connecting hole 3410. The lower horizontal plate has a waist hole.

[0141] The rotating pin 336 passes through the waist hole and is connected to the sliding plate 332 by threads.

[0142] The two ends of the lateral rotating base 331 are respectively provided with linear guide rails 337, and the bottom of the slide plate 332 is provided with a guide rail slider 338, which is connected to the linear guide rail 337.

[0143] The lateral rotating base 331 is equipped with a worm gear screw jack 339 that drives the sliding plate 332 to move.

[0144] The Teflon wear-resistant plate has a coating on its surface, and its coefficient of friction with iron is very small, which can produce relative slippage. One end of the heading fine-tuning base 341 is connected to the top of the slewing support 333, and the other end is constrained by the rotating connecting block 335 and the rotating pin 336. The rotating connecting block 335 has a waist hole in the front-back direction, the diameter of which is basically the same as the pin size, but the tolerance is slightly larger. The bottom of the rotating pin 336 is threaded and connected to the slide plate. The rotating pin 336 has a step on it, leaving a gap of 1-2mm to press against the rotating connecting block 335.

[0145] When the hand-cranked rotation speeds of the two sets of worm gear screw jacks 339 are the same, the assembly and adjustment platform can be moved laterally as a whole. When the hand-cranked rotation speeds of the two sets of worm gear screw jacks 339 are the same or only one of them is rotated, the assembly and adjustment platform can rotate with the slewing support as the rotation point.

[0146] like Figure 13-16 As shown, the lifting platform 2 includes a pair of parallel lifting columns 21, which are vertically mounted on the frame body 11. The lifting columns 21 are connected to the fork extension mechanism 22 via a folding mechanism 24. The fork extension mechanism 22 is equipped with a rope lowering mechanism 23.

[0147] The rope lowering mechanism 23 includes a drum winch 231, a top lifting beam 232, a fixed pulley 233, and a hook rope 234.

[0148] The drum winch 231 is located on the top of the uppermost platform of the fork extension mechanism 22. The lifting top beam 232 is connected to the outside of the uppermost platform of the two fork extension mechanisms 22. Below the lifting top beam 232, there is a fixed pulley 233 for supporting and guiding the lowering of the hook rope 234 (i.e., the rope with the hook) on the drum winch 231.

[0149] The top beam 232 of the hoisting system is provided with grooved guide blocks 235 on both sides.

[0150] The fork extension mechanism adopts a mature two-stage fork extension mechanism on the market. It drives the left and right fork extension mechanisms to move synchronously through a set of side-mounted right-angle geared motors 221 and synchronous shafts 222. Its internal structure is usually guided by a double-speed chain and roller structure. The mechanism has a long extension range and the load can be customized according to the actual situation, which meets the requirements of this application.

[0151] The rope lowering mechanism 23 is arranged on the uppermost platform of the fork extension mechanism. It adopts two independent roller winches 231 and achieves synchronous rope lowering through servo reduction motor control. The outermost side of the uppermost platform of the fork extension mechanism is equipped with a lifting top crossbeam 232, and the bottom of the crossbeam is equipped with a fixed pulley 233 to support and guide the lowering of the hook rope 234. The two sides of the lifting top crossbeam 232 are equipped with grooved guide blocks 235. The inner three sides of the crossbeam are trapezoidal. During the process of controlling the rope to move upward and tighten, the lifting universal crossbeam 41 is self-guided and smoothly aligned in the groove of the grooved guide block 235. Finally, the lifting universal crossbeam 41 is stably and rigidly connected to the lifting platform through the limit pin, which is conducive to ensuring the smooth implementation of subsequent assembly and fine-tuning work.

[0152] The folding and lowering mechanism 24 includes a pair of hoisting folding columns 241, a manual winch 242, a lowering support column 243, a support pulley 244, a steel wire rope 245, and a self-locking hook 246.

[0153] The lifting folding column 241 is hinged to the lifting column 21 in a one-to-one correspondence, the fork extension mechanism 22 is connected to the lifting folding column 241, and a pair of lifting folding columns 241 are connected by a horizontal square tube 247.

[0154] The manual winch 242 and the folding support column 243 are respectively installed on the frame body 11 and located between a pair of lifting columns 21.

[0155] The supporting pulley 244 is located on top of the collapsed supporting column 243 and is used to support and guide the steel wire rope 245.

[0156] One end of the steel wire rope 245 is connected to a manual winch 242, and the other end is connected to a horizontal square tube 247 via a self-locking hook 246.

[0157] Equipped with a folding and lowering mechanism 24, the lifting platform has a folding and lowering function. By cranking the manual winch 242, the wire rope is hooked through the self-locking hook 246 to the interface of the horizontal square tube 247 in the middle of the lifting folding column 241, so that the entire lifting platform can be lowered, which meets the requirements of miniaturized transportation design.

[0158] like Figure 17-19 As shown, the lifting interface mechanism 4 includes a general-purpose lifting beam 41 and several assembly hooks 42.

[0159] The universal lifting beam 41 is connected to the grooved guide blocks 235 on both sides of the top lifting beam 232.

[0160] Several assembly hooks 42 are evenly distributed at the bottom of the general lifting beam 41.

[0161] If three sets of assembly hooks 42 are set, the middle set of assembly hooks is used when lifting a large object, and the front and rear sets of assemblies are used when lifting two sets of assemblies at the same time.

[0162] It also includes a foldable assembly lifting beam 43, which includes a rectangular tube 431 and a rotating connecting plate 434. The bottom of the rectangular tube 431 is provided with a combined hanging bracket interface 432. The rectangular tube 431 is hinged to the hanging bracket pivot 433 on one side of the general lifting beam 41.

[0163] The general-purpose hoisting beam 41 is provided with a retractable pin hole 411 and an extended pin hole 412. The bottom ends of the rotating connecting plate 434 are respectively provided with a rotating shaft 435 and a positioning pin 436. The rotating shaft 435 is used to connect the rectangular tube 431, and the positioning pin 436 is used to connect the retractable pin hole 411 or the extended pin hole 412.

[0164] The rotating connecting plate 434 is provided with a handle 437 for easy operation.

[0165] When the other end of the rotating connecting plate 434 is fixed in the unfolded state pin hole 412 by the positioning pin 436 through the handle 437, the combined hanging bracket is unfolded; when it is fixed in the retracted state pin hole 411 by the positioning pin 436, the combined hanging bracket is retracted.

[0166] This invention uses a hoisting platform 2 to simultaneously pick up one or two assemblies from the transport vehicle (depending on the structure of the multi-unit hanger single-row combination), and place them sequentially on the same row of assembly beam brackets (i.e., bracket assemblies) on the assembly adjustment platform 3. After the assemblies are placed, the hoisting platform 2 picks up the hangers to be assembled from the transport vehicle, and then the assembly adjustment platform 3 completes the mounting of the assemblies on the innermost row of assembly beam brackets in one go. The operation of the three rows of assemblies is completed in three steps in the order from the inside out. Finally, the hoisting platform 2 lifts the assembled multi-unit combination onto the hanger vehicle, thus completing the entire assembly operation process.

[0167] like Figure 20-22 As shown, the vehicle frame body 11 is provided with a driving system structure 12, a steering system structure 13, a traction mechanism 14, a parking mechanism 15, and an anti-roll support mechanism 16.

[0168] The present invention rationally arranges the chassis body 11, leaving a large space on one side in the middle for placing the assembly and adjustment platform 3, and placing the hoisting platform 2 on the other side. The power battery is arranged under the hoisting platform, and the accessory box and the electronic control box are placed at the front and rear of the chassis, respectively.

[0169] The relevant structures on the frame body 11 are conventional technologies, specifically:

[0170] The driving system structure 12 is mainly composed of solid rubber wheels and double wishbone suspension connected to a dual-output right-angle reduction motor 122 located in the middle of the vehicle body via a universal coupling 121. The spatial structure design is reasonable and compact.

[0171] The steering system structure 13 mainly adopts the form of a gear transmission group 131, with one end connected to a right-angle reduction motor 132 (to prevent the motor from protruding from the body skin through steering), and the other end connected to a large sector gear concentric with the traction steering shaft 142. The main body of the traction mechanism 14 is the traction interface steering plate 141, with the traction steering shaft 142 located in the middle. One end protruding from the body has a traction rod interface, and the other end is used to install and fix the steering system structure 13.

[0172] In addition, during the assembly, hoisting, and transfer process, to ensure that the vehicle body does not shift, parking mechanisms 15 are provided at the four corners of the chassis. The parking mechanism 15 mainly consists of a worm gear screw jack 151 and a spherical foot flange plate 152. The worm gear screw jack 151 is fixed on the frame. The motor controls the lifting and lowering of the trapezoidal screw, which drives the spherical foot flange plate 152 to extend and retract, thereby achieving contact and separation with the ground and completing the parking work.

[0173] Because the lifting platform needs to extend laterally across the width of the vehicle during operation, when the multi-unit trailer assembly is moved laterally onto the trailer after assembly, the center of gravity of the entire assembled vehicle is significantly offset relative to the vehicle's center. To ensure stability and prevent tipping, two sets of anti-rollover support mechanisms 16 are installed on one side of the chassis. Each anti-rollover support mechanism 16 has two sets of pin holes: one is a pivot hole for rotation around the center, and the other is a fixing hole for extending and retracting the mechanism. When extension is required, the quick-release pin 161 is removed, and the support leg is rotated to extend it beyond the width of the chassis. This ensures that the vehicle's center of gravity falls within the support position, preventing tipping or overturning.

[0174] like Figure 23 As shown, after the folding support column 241 is lowered, the lifting platform 2 and the assembly and adjustment platform 3 are secured together by tightening straps to ensure no interference. The folding down design further reduces the overall vehicle height, ensuring stable transport.

[0175] This invention optimizes the structural layout to meet the assembly task of multiple components, while the vehicle body structure is compact, has a small footprint, and is lighter in weight than other similar assembled vehicles.

[0176] The assembly and adjustment platform features a staggered design for the adjacent rows of independent height adjustment jacks in the front-to-back and height fine-tuning structures, ensuring human-machine efficiency during manual operation. In addition, each jack is equipped with an independent scale for operators to quantitatively adjust the height, making it highly practical.

[0177] The lifting interface mechanism, through its universal design, integrates the functions of both lifting assembled components and lifting multi-unit combination hangers. Switching between lifting and picking up objects can be performed without changing the interface, eliminating unnecessary intermediate time and making the lifting mechanism more efficient.
