Description

Technical Field

[0001] The invention relates to the technical field of bus assembly, and in particular to a high-position support sequence transfer device and method for a full-load bus. Background Art

[0002] The manufacturing process of full-load buses is complex, and the challenges faced in the production process are becoming increasingly prominent. Among them, the high-position support and transfer links of the body assembly are important parts of the manufacturing process, which directly affect production efficiency and cost. In the traditional production process of full-load buses, the support and transfer of the body often rely on manual operation and simple four-wheel lifting machinery and equipment. However, the complex structure and large size of full-load buses make it difficult for traditional support and transfer methods to meet the needs of efficiency, accuracy and safety. In the process of high-position support of the body, if the position of the support point is improperly selected or the support force is unevenly distributed, it may lead to serious consequences such as deformation, damage or even overturning of the body. In the process of transfer, if the operation is improper or the equipment fails, it may also cause the body to lose balance during movement, thereby causing safety accidents.

[0003] There are some high-position work vehicles for buses in the prior art. For example, CN207106694U discloses a bus chassis rear-mounted process flow support vehicle, including a front process vehicle and a rear process vehicle. The front and rear process vehicles are both composed of a base and a bow-shaped crossbeam. Wheels are provided on the base, and retractable support arms are provided in the middle of both sides of the base; CN112896382A discloses a high-position work vehicle for full-load bus chassis assembly, including a bottom frame and guide wheels. By supporting the front and rear of the vehicle body on the high-position work vehicle, the work content is distributed at each workstation according to the process.

[0004] Although the above solutions have solved the problem of uneven force and easy deformation of the vehicle body during transportation to a certain extent, they are all supported at both ends of the vehicle body by the same work vehicle structure, and the middle section of the vehicle body has no support, so the work vehicle is under greater pressure. In addition, although the above solutions are equipped with a positioning device, when the initial positioning is inaccurate, the vehicle body needs to be lifted again to adjust the position of the work vehicle, which is a cumbersome operation. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a high-position support transfer device and method for a full-load passenger car, which can ensure that the car body remains balanced during movement, effectively avoid safety accidents caused by unstable support, and improve the transfer efficiency.

[0039] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0040] Embodiment 1:

[0041] This embodiment provides a high-position support sequence transfer device for a full-load passenger car, such as Figure 1 and Figure 6 As shown, it includes end high-position support fixtures 200 and middle high-position support fixtures 400 arranged along the ground drag chain line 100, and each end of the full-load vehicle body 300 is supported by a set of end high-position support fixtures 200, and the middle of the full-load vehicle body 300 is supported by the middle high-position support fixture 400. The middle high-position support fixture 400 cooperates with the two sets of end high-position support fixtures 200 to stably support the full-load vehicle body 300, thereby improving the stability and safety during the transfer process. In addition, the middle high-position support fixture 400 is first supported in the middle of the full-load vehicle body 300, and then the corresponding support point position of the end high-position support fixture 200 is adjusted to avoid multiple hoisting and improve the installation efficiency of the transfer device and the full-load vehicle body 300.

[0042] Specifically, Figure 2 and Figure 4 As shown, the end high-position support tooling 200 mainly includes a support base 205, a double-linkage lifting mechanism, a first moving component, and a first supporting beam 209. The first moving component can move along the floor drag plate chain track 102, and it includes a plurality of first track wheels 204. The two tracks of the floor drag plate chain track 102 correspond to the same number of first track wheels 204, for example: each track corresponds to two first track wheels 204; the number of first track wheels 204 can be set according to actual requirements as long as stable movement can be guaranteed.

[0043] The shape of the support base 205 can be set arbitrarily. In this embodiment, considering the simplicity of the structure and the ease of installation, the support base 205 is set to a rectangular frame structure, and the first rail wheels 204 are installed in pairs at the bottom of the support base 205.

[0044] The double-linked lifting mechanism is installed on the upper side of the support base 205, and the first supporting beam 209 is connected to the top of the double-linked lifting mechanism. The height of the first supporting beam 209 can be adjusted through the double-linked lifting mechanism to achieve accurate positioning and stable support of the vehicle body.

[0045] The double-linked lifting mechanism includes two lifts 202, with a lift 202 installed at each end of the support base 205; the lift 202 is installed with a hand wheel 201, and a connecting rod 211 is connected between the two lifts 202, and the connecting rod 211 is connected to the lift 202 through a coupling 208. Rotating the hand wheel 201 can realize the synchronous movement of the two lifts 202, so that the first supporting beam 209 can be lifted in a horizontal state.

[0046] The extension direction of the first support beam 209 is parallel to the extension direction of the single floor drag chain track 102. Two or more limit pressure plates 210 are installed along the length direction of the first support beam 209. The limit pressure plates 210 are connected to the grille beam 301 of the full load-bearing vehicle body 300, wherein the grille beam 301 and the limit pressure plates 210 are connected by bolts. The first support beam 209 is provided with a plurality of bolt fixing holes to facilitate adjustment of the spacing of the limit pressure plates 210 for different vehicle models.

[0047] When the end high-position support tooling 200 moves to below the corresponding end body support point of the full-load body 300, there is still some deviation between the positions of the grille crossbeam 301 and the limiting pressure plate 210. Therefore, a slide groove 206 is set on the upper side of the support base 205, and the slide groove 206 is set at the end of the support base 205, and the setting direction of the slide groove 206 is along the width direction of the support base 205; the support seat 207 of the lift 202 is set in the slide groove 206, and the position of the limiting pressure plate 210 can be fine-tuned by moving the support seat 207 of the lift 202 relative to the slide groove 206, thereby improving the alignment accuracy of the limiting pressure plate 210 and the grille crossbeam 301, which is convenient for installation.

[0048] The support base 205 is also equipped with a first limiting assembly, which is fixed to the floor drag chain track 102 to limit the end high-position support tooling 200. In this embodiment, the first limiting assembly includes a first support plate 212, a first limiting seat and a first limiting pin 203, the first limiting seat is fixed to the support base 205, and the first support plate 212 is fixed to the upper side of the first limiting seat; the first limiting seat is provided with a through hole for the first limiting pin 203 to pass through, the first limiting pin 203 has a handle perpendicular to the limiting pin body, and the support plate is provided with a groove for carrying the handle.

[0049] like Figure 2 As shown, the first stop pin 203 is in a lifted state, that is, it is not inserted into the positioning hole of the floor board chain track 102, and the handle is set in the groove of the support plate. Figure 4 As shown, the first stop pin 203 is in the lowered state, that is, the first stop pin 203 is inserted into the positioning hole of the floor drag chain track 102, and the handle is out of the groove of the support plate. When the first stop pin 203 is changed from the raised state to the lowered state, it is only necessary to properly lift the first stop pin 203 and rotate it to disengage the handle from the groove, which is simple to operate.

[0050] like Figure 3 and Figure 5 As shown, the middle section high position support tooling 400 includes a support frame, a second movable assembly installed at the bottom of the support frame, and the second movable assembly includes a plurality of second rail wheels 404 . The number of the second rail wheels 404 may be the same as or different from that of the first rail wheels 204 .

[0051] After the full-load vehicle body 300 is hoisted, it is pre-supported by the middle section high position support tooling 400. In order to ensure the support stability, the middle section high position support tooling 400 has multiple vehicle body support points, and the multiple vehicle body support points are realized by the support frame. The support frame includes a support base frame 401 and a second support beam 402. The second track wheels 404 are installed in pairs at the bottom of the support base frame 401. At least two second support beams 402 are connected to the upper side of the support base frame 401. Each second support beam 402 is sequentially arranged along the extension direction of the floor drag chain track 102, and the second support beam 402 forms an effective support for the full-load vehicle body 300.

[0052] The support base 401 is installed with a second limit assembly, which includes a second limit pin 403, a second limit seat and a second support plate 405. Its structure is the same as that of the first limit assembly. Here, "first" and "second" are distinguished for the convenience of description, and its specific structure will not be repeated.

[0053] The end high-position support tooling 200 and the middle high-position support tooling 400 of this embodiment are made of high-strength materials to ensure that they can withstand the weight of the vehicle body and possible impact force during the support process while maintaining the stability and balance of the vehicle body.

[0054] In this embodiment, the transfer device is placed on the floor drag chain track 102 according to the body length and the support point position, the full-load body 300 is hoisted above the middle high-position support tooling 400, and then the end high-position support tooling 200 is adjusted to the corresponding support point position in turn, and then the corresponding limit pin is rotated and inserted into the positioning hole of the floor drag chain track 102; the hand wheel 201 is rotated to make the first supporting beam 209 contact with the grid beam 301, and the slide groove 206 is fine-tuned to ensure that the limit pressure plate 210 accurately fixes the grid beam 301 to the supporting beam.

[0055] During the transfer process, the transfer device and the floor drag chain line 100 are fixed with limit pins, and move with the track through the track wheels to ensure that the vehicle body remains balanced during the movement, effectively avoiding safety accidents caused by unstable support.

[0056] Embodiment 2:

[0058] 1) According to the length and support point positions of the full load-bearing vehicle body 300, two end high-position support fixtures 200 and one middle high-position support fixture 400 are placed on the floor drag chain track 102.

[0059] 2) The full-load vehicle body 300 is hoisted above the middle high-position support tooling 400.

[0061] 4) Rotate the hand wheel 201 to make the first support beam 209 contact the grille beam 301 , and make fine adjustments through the slide groove 206 to ensure that the limit pressure plate 210 accurately fixes the grille beam 301 to the support beam 209 .

[0062] 5) According to the production rhythm of the workstation, the floor drag chain line 100 is started, and the sequence transfer device is linked to the next workstation through the first limit pin 203 and the second limit pin 403 to ensure safe sequence transfer and improve production efficiency.
