Description

Technical Field

[0001] The invention belongs to the technical field of beam erection vehicles, and in particular relates to a multifunctional beam erection vehicle integrating steel beam unloading, assembly and hoisting. Background Art

[0002] As the core hub of modern transportation systems, bridges transcend geographical barriers and connect regional networks, not only ensuring the efficient flow of people and materials, but also promoting economic and social development and cultural integration at a deeper level. In the evolution of bridge construction technology, I-type steel beam bridges have always occupied an important position due to their simple structure and excellent mechanical properties. However, the current steel beam bridge construction technology still has significant limitations: During construction in the low-pier area, the conventional process requires densely setting up temporary auxiliary piers between the main bridge piers for segmented splicing and hoisting. Although this method is easy to implement, it has the following shortcomings: (1) To ensure the assembly accuracy of the steel beam units, the top surfaces of all auxiliary piers must be kept strictly horizontal, and the elevation control accuracy requirements are high, which significantly increases the workload of measurement and positioning; (2) The auxiliary piers are set up densely, and each steel beam unit needs to be supported separately, which makes the process complicated and affects the construction efficiency; (3) After the steel beam is fully closed, all auxiliary piers need to be dismantled. The repeated erection and dismantling of a large number of temporary support structures not only prolongs the construction period, but also results in additional material loss and manpower investment.

[0003] In the high-rise area of the pier, after the beam transporter transports the beam unit to the bridge position, it must first be unloaded by the lifting equipment onto the sleepers for assembly, and then the overall lifting and installation is carried out. This process has the following main defects: (1) Ground assembly has strict space requirements for the work site. The construction area must not only meet the basic width for temporary stacking and assembly of beam units, but also have a high degree of flatness. When the site is not flat enough, the construction workers need to repeatedly adjust the ground elevation of adjacent beam units and eliminate the errors during splicing by leveling with pads, which increases the workload of on-site leveling; (2) In the double-machine lifting operation mode, the two cranes need to maintain sufficient standing distance and boom extension space. Narrow sites can easily lead to limited equipment layout, which not only affects the lifting efficiency, but also poses safety risks due to insufficient operating space. (3) Each steel beam is composed of multiple steel beam units. During assembly, the two beam units are connected by bolts. The bolts are tightened one by one by the workers. Although the bolting work is simple, the number of bolts is large and cannot be completed quickly, which wastes time. In addition, the bolts tightened by different workers are different in tightness, which makes the quality of the steel beam unguaranteed. In summary, these constraints lead to low utilization of construction machinery and poor process connection, which ultimately prolongs the construction period and increases construction costs.

[0004] Therefore, it is urgent to design a multifunctional beam erecting vehicle that integrates steel beam unloading, assembling and hoisting to solve the above problems. Summary of the Invention

In the U-shaped transport rail 6, the steel plate transport arm 801 is arranged in the outer chute 302-1A, and the electric bolt tightener 802 and the steel plate transport arm 801 are arranged in the inner chute 1 302-1B.

In the vertical transport rail 7, an electric bolt tightener 802 and a steel plate transport arm 801 are arranged in the second inner chute 302-1D, a motor is placed in the second motor chute 302-1E, and the steel plate transport arm 801 in the second inner chute 302-1D cooperates with the steel plate transport arm 801 in the first inner chute 302-1B; In the embodiments of this application, refer to the attached Figure 18-25 The beam unloading system 2 includes a beam connecting plate assembly 201 and a beam transporting plate assembly 202 which can be spliced together, wherein the beam connecting plate assembly 201 is rotatably connected to the rear side of the beam erecting vehicle body. The free ends of the beam transport plate assembly 202 and the beam connecting plate assembly 201 are spliced to realize a detachable connection between the beam transport plate assembly 202 and the beam connecting plate assembly 201. Specifically, one end of the retracting member 203 is rotatably connected to the beam erection vehicle body 1, and the other end is rotatably connected to the beam connecting plate assembly 201. The retracting member 203 is a telescopic hydraulic rod 1, which is a mature product available on the market and is not improved in the present invention. In the embodiments of this application, refer to the attached Figure 18 As shown, the beam connecting plate assembly 201 and the beam transport plate assembly 202 have the same structure and both include a bearing plate 201-1, hydraulic legs 201-2, a plurality of longitudinal conveyor belts 201-3, and a plurality of transverse conveyor belts 201-4. One side of the bearing plate 201-1 is rotatably connected to the rear side of the beam erection vehicle body 1 via a pin shaft, and each longitudinal conveyor belt 201-3 and transverse conveyor belt 201-4 can be controlled independently. Refer to the attached Figure 19 As shown, a through-joining piece 201-1A is provided at the end of the bearing plate 201-1 of the beam transport plate assembly 202, and a second joining piece 201-1B that matches the first joining piece 201-1A is provided at the end of the bearing plate 201-1 of the beam connection plate assembly 201. When the bearing plate 201-1 of the beam connection plate assembly 201 rotates from top to bottom relative to the beam erection vehicle body 1, the first joining piece 201-1A and the second joining piece 201-1B thereon are hooked together, completing the splicing of the beam transport plate assembly 202 and the beam connection plate assembly 201. Further references Figure 20 As shown, splicing piece 1 201-1A is rotatably connected to the end of the bearing plate 201-1 via a hinge 202-1C. One end of a spring 202-1D is connected to the bearing plate 201-1, and the other end is connected to splicing piece 1 201-1A. This structural design satisfies the requirement for stable overlap of the two bearing plates 201-1 in an inclined state. The supporting force of the two bearing plates 201-1 is provided by the hydraulic support legs 201-2, and splicing piece 1 201-1A and splicing piece 2 201-1B only provide an oblique connection. When unloading the beam, both load-bearing plates 201-1 are in an oblique, angled position. The purpose of providing joint piece 1 201-1A and joint piece 2 201-1B is to provide a restraining force to keep the two load-bearing plates relatively fixed, preventing excessive relative displacement in an oblique direction. Hinges 202-1C and springs 202-1D are provided at the ends of load-bearing plates 201-1, ensuring that this oblique restraining force is not disrupted after the overlap. Spring 202-1D holds joint piece 1 201-1A in place, preventing it from rotating downward under gravity in its natural state. This configuration provides a wider vertical overlap range, thereby preventing damage to the joint pieces due to the hydraulic support legs 201-2 being unable to accurately control the height of the load-bearing plates 201-1. Furthermore, it reduces wear on the joint pieces caused by multiple overlaps.

[0030] There are two hydraulic legs 201-2, which are retractable and symmetrically installed at the lower end of the bearing plate 201-1, and are used to support and adjust the height of the bearing plate 201-1; A plurality of longitudinal conveyor belts 201-3 are arranged at intervals on the upper surface of the bearing plate 201-1 and can be raised and lowered relative to the bearing plate 201-1; each transverse conveyor belt 201-4 is arranged between every two longitudinal conveyor belts 201-3 and can be raised and lowered relative to the bearing plate 201-1; In the embodiments of this application, refer to the attached Figure 21-22 As shown, the longitudinal conveyor belt 201-3 and the transverse conveyor belt 201-4 have the same structure, and both include a transmission assembly 201-3A, a small crawler belt 201-3B, and a small jack 201-3C. The transmission assembly 201-3A is used to drive the small crawler belt 201-3B to rotate. The small crawler belt 201-3B is sleeved on the outer periphery of the transmission assembly 201-3A. The small jacks 201-3C are arranged on both sides of the transmission assembly 201-3A to adjust the height of the transmission assembly 201-3A. Further, see the attached Figure 23-25 As shown, the transmission assembly 201-3A includes a main structural plate 201-3A1, four large transmission gear rods 201-3A2, a transmission shaft 201-3A3, a motor 201-3A4, and a structural gear rod 201-3A5; Among them, four large transmission gear rods 201-3A2 are arranged in groups of two at the ends on both sides of the main structural plate 201-3A1. The inner side of the small crawler 201-3B is engaged with the large transmission gear rods 201-3A2 and is sleeved on the main structural plate 201-3A1. The two large transmission gear rods 201-3A2 in each group are fixedly connected by a transmission shaft 201-3A3, and a motor 201-3A4 is provided on the transmission shaft 201-3A3. When in use, the motor 201-3A4 drives the transmission shaft 201-3A3 to rotate, and the transmission shaft 201-3A3 drives the two large transmission gear rods 201-3A2 in each group to rotate. The rotation of the large transmission gear rods 201-3A2 drives the small crawler 201-3B to rotate. In order to ensure the stability and load-bearing capacity of the small crawler 201-3B during rotation, structural gear rods 201-3A5 are arranged at equal intervals around the main structural plate 201-3A1 through rotating shafts. The structural gear rods 201-3A5 are engaged with the small crawler 201-3B. The side of the main structural plate 201-3A1 is fixedly connected to a small jack 201-3C for adjusting the height of the main structural plate 201-3A1. The use process of beam unloading system 2 is as follows: S1. First, the beam assembly 202 is installed on the beam transport vehicle frame, the beam unit is fixed by unloading the conveyor belt position on the beam plate, and the beam transport vehicle is a multi-vehicle continuous transport; S2. After the beam transporter transports the beam unit to the construction site, adjust the position of the beam transporter to align with the beam erection vehicle; S3. The bearing plate 201-1 on the connecting beam plate assembly 201 is rotated relative to the beam erection vehicle body 1 by retracting the member 203, thereby approaching the beam transport plate assembly 202. The bearing plate 201-1 on the connecting beam plate assembly 201 is adjusted in conjunction with the hydraulic support legs 201-2 in the connecting beam plate assembly 201, so that the connecting beam plate assembly 201 and the beam transport plate assembly 202 are overlapped together to form a whole. S4. Then place the beam unit on the beam transport plate assembly 202, and use the small jack 201-3C to lower the height of the longitudinal conveyor belt 201-3 on the beam transport plate assembly 202 so that it is out of contact with the beam unit, and the transverse conveyor belt 201-4 is in contact with the beam unit. Each column of transverse conveyor belts 201-4 on the beam transport plate assembly 202 controls one beam unit, and the three columns of transverse conveyor belts 201-3 cooperate with each other, and use the small crawler 201-3B that can move left and right to adjust the transverse position of the beam unit so that there is sufficient transverse spacing between the beams.

[0031] S5. The horizontal conveyor belt 201-4 on the beam transport plate assembly 202 is lowered by the small jack 201-3C so that it is out of contact with the bottom of the beam unit. Then, the longitudinal conveyor belt 201-3 on the beam transport plate assembly 202 is raised by the small jack 201-3C so that it contacts the bottom of the beam unit. The longitudinal conveyor belt 201-3 simultaneously transports each beam unit to the beam plate assembly 201; S6. Use the small jack 201-3C to lower the height of the longitudinal conveyor belt 201-3 in the beam-plate assembly 201 so that it is out of contact with the beam unit, and the transverse conveyor belt 201-4 is in contact with the beam unit. Each row of transverse conveyor belts 201-4 on the bearing plate 201-1 of the beam-plate assembly 201 controls one beam unit, and the three rows of transverse conveyor belts 201-4 use small crawlers 201-3B that can move left and right to adjust the transverse position of the beam unit.

[0032] S7. Use the small jack 201-3C to lower the height of the transverse conveyor belt 201-4 in the beam-plate assembly 201 so that it is out of contact with the bottom of the beam unit, and then use the small jack 201-3C to adjust the height of the longitudinal conveyor belt 201-3 in the beam-plate assembly 201 so that it is in contact with the bottom of the beam unit. The longitudinal conveyor belt 201-3 transports each beam unit to the beam-erecting vehicle body 1 at the same time.

[0033] In the embodiments of this application, refer to the attached Figure 26 As shown, there are two hanging beam systems 4, which are symmetrically arranged on the main body of the beam erection vehicle 1, and include a crane arm 601, a sling 602 and a direction control mechanism 603. The crane arm 601 is rotatably arranged on the direction control mechanism 603 through a rotating seat, and the sling 602 is hung at the free end of the crane arm 601 for connecting with the steel beam unit. The direction control mechanism 603 is arranged on the main body of the beam erection vehicle 1 and is used to adjust the direction and angle of the crane arm 601 to facilitate the lifting of the steel beam unit. In the embodiment of the present application, the direction control mechanism 603 includes a lower base plate 603-1, an upper base plate 603-2, a drive assembly, and an angle adjustment member. The lower base plate 603-1 is welded to the beam erection vehicle body 1 to provide a stable support force. The upper end surface of the upper base plate 603-2 is rotatably connected to the crane arm 601 through a rotating seat; the driving assembly is arranged between the lower base plate 603-1 and the upper base plate 603-2, and is used to drive the upper base plate 603-2 to rotate, thereby driving the crane arm 601 to rotate in the direction to achieve direction adjustment; One end of the angle adjustment member is rotatably connected to the upper base plate 603-2 via a rotating seat, and the other end is rotatably connected to the crane arm 601 via a rotating seat, for adjusting the angle between the crane arm 601 and the upper base plate 603-2; In the embodiment of the present application, the drive assembly includes a power gear 603-3, a transmission gear 603-4, and a motor 603-5. The power gear 603-3 is fixedly connected to the output end of the motor 603-5. The motor 603-5 is disposed on the upper base plate 603-2, and its output shaft movably passes through the upper base plate 603-2 and is fixedly connected to the power gear 603-3. The upper end of the transmission gear 603-4 is fixedly connected to the upper base plate 603-2, and the lower end is rotatably connected to the lower base plate 603-1 via a bearing, and is simultaneously meshed with the power gear 603-3. When the motor 603-5 drives the power gear 603-3 to rotate, the power gear 603-3 drives the transmission gear 603-4 to rotate, and the transmission gear 603-4 rotates relative to the lower base plate 603-1, and at the same time drives the upper base plate 603-2 to rotate synchronously, and the upper base plate 603-2 synchronously drives the crane arm 601 to rotate, thereby achieving the purpose of adjusting the direction of the crane arm 601.

[0034] In the embodiment of the present application, the angle adjustment member is a telescopic hydraulic rod 604. By controlling the extension or contraction of the telescopic end of the telescopic hydraulic rod 604, the angle between the crane arm 601 and the upper base plate 603-2 is adjusted. The use process of the multifunctional beam erecting vehicle integrating steel beam unloading, assembly and hoisting of the present invention is as follows: First, the vehicle main platform 1 controls the position of the beam erecting vehicle to facilitate the beam unloading system 2 to unload the beam units from the beam transport vehicle. At the same time, the beam unloading system 2 transports the beam units sequentially to the steel beam direction adjustment plate 301. The steel beam direction adjustment plate 301 is raised and rotated by a hydraulic device, so that the position and direction of the beam units thereon are adjusted to correspond to the steel beam assembly slots 303. Then, multiple beam units are pushed into the steel beam assembly slots 303 on both sides, and the beam units transported later to the steel beam direction adjustment plate 301 are adjusted to correspond to the beam units in the steel beam assembly slots 303. Next, the beam unit in the steel beam assembly slot 303 and the end of the beam unit on the steel beam direction adjustment plate 301 are assembled using the steel beam assembly device 302. Specifically: Step 1: Install the nut on the nut fixing plate 2 302-7 and the bolt on the bolt fixing plate 302-8; Step 2: Overlap the nut fixing plate 2 302-7 with the connecting steel plate and place them into the steel plate fixing housing 302-5 on one side of the U-shaped transport rail 6. The steel plate fixing housing 302-5 is located in the outer slide groove 302-1A of the U-shaped transport rail 6. Then, the steel plate fixing housing 302-5 on the steel plate transport arm 801 on one side of the U-shaped transport rail 6 is controlled to transport the nut fixing plate 2 302-7 to the steel plate fixing housing 302-5 in the vertical transport rail 7 in sequence. Finally, all vertical transport rails 7 and one steel plate transport arm 801 on the inner side of the U-shaped transport rail 6 are fixed with the nut fixing plate 2 302-7. Step 3: Overlap the bolt fixing plate 302-8 with the connecting steel plate and place it into the steel plate fixing housing 302-5 on the other side of the U-shaped transport slide 6. The steel plate fixing housing 302-5 is located in the outer slide groove 302-1A of the U-shaped transport slide 6. Then, control the steel plate fixing housing 302-5 on the steel plate transport arm 801 on the other side of the U-shaped transport slide 6 to transport the bolt fixing plates 302-8 to the steel plate fixing housing 302-5 in the vertical transport slide 7 in sequence. The transport process is as follows: The larger surface of the overlapping body (hereinafter referred to as the overlapping body) between the bolted plate 302-8 and the connecting steel plate is initially vertical. After reaching the top of the U-shaped transport rail 6, the larger surface is adjusted to a horizontal position. At this time, the first gear rod 302-6B is rotated, which drives the second gear rod 302-6B, which in turn drives the steel plate fixing housing 302-5 with the overlapping body to rotate counterclockwise 90 degrees. At this point, the larger surface of the overlapping body is restored to a vertical position. The position of the sliding transport arm on the U-shaped transport rail 6 is then adjusted to align with the steel plate transport arm 801 on the vertical transport rail 7. The electric rubber conveyor belt 302-5C of the steel plate transport arm 801 on the U-shaped transport slide 6 transports the overlapping body vertically downward until half of the overlapping body leaves the electric rubber conveyor belt 302-5C of the steel plate transport arm 801 on the U-shaped transport slide 6, and the steel plate transport arm 801 on the vertical transport slide 7 moves upward until the rubber conveyor belt 302-5C on the steel plate transport arm 801 on the vertical transport slide 7 contacts the overlapping body (a part of the overlapping body penetrates into the electric rubber conveyor belt 302-5C), and the micro hydraulic telescopic rods 302-5B on both sides of the electric rubber conveyor belt 302-5C squeeze the electric rubber conveyor belt 302-5C inward, thereby clamping the overlapping body from the steel plate transport arm 801 on the U-shaped transport slide 6, and the micro hydraulic telescopic rods 302-5B on the steel plate transport arm 801 on the U-shaped transport slide 6 shrink, and the electric rubber conveyor belt 302-5C on the steel plate transport arm 801 on the U-shaped transport slide 6 is loosened and separated from the overlapping body. Then the electric rubber conveyor belt 302-5C of the steel plate transport arm 801 on the vertical transport slide 7 works to move the entire overlapping body to the inside of the steel plate fixing shell on the vertical transport slide 6, completing the steel plate transport process. The transportation steps of the nut fixing plate 302-7 and the overlapping body connected to the steel plate are the same as the transportation steps of the bolt fixing plate 302-8, which will not be repeated here. Finally, all vertical transport slides 7 and a steel plate transport arm on the inner side of the U-shaped transport slide 6 are fixed with a nut fixing plate 2 302-7, and the bolt fixing plate 302-8 and the nut fixing plate 2 302-7 are correspondingly distributed on a group of vertical transport slides 7, and can cooperate to tighten the bolts and nuts; Step 4: Use each transport arm to transport 801 and adjust the connecting steel plates on the bolt side and the nut side so that they are aligned with the bolt holes of the beam unit and close to the beam unit ribs.

[0035] Step 5: The electric bolt tightener 802 starts working and tightens each bolt.

[0036] Step 6: Repeat steps 2-5 to tighten the top bolts of the beam unit; Step 7: Overlap the bolt fixing plate 302 - 8 and the connecting steel plate and pass them through the steel plate transport arm, so that the connecting steel plate with the bolt fixing plate 504 is closely attached to the upper surface of the beam unit bottom plate.

[0037] Step 8: Place the nut into the hole of the nut fixing plate 502 on the bottom steel plate conveyor belt 5, place the connecting steel plate on the upper surface of the nut fixing plate 502, and adjust the height of the nut fixing plate 502 through the hydraulic telescopic device until it is close to the lower surface of the beam unit.

[0038] Step 9: Turn the electric bolt tighteners 803 downward and tighten the bolts connecting the steel plates of the beam unit bottom plate in sequence to complete the connection between the two beam units.

[0039] Step 10: Push the two connected beam transport units into the left and right steel beam assembly slots 303 .

[0040] Step 11: Repeat steps 2 to 9 until the end of the assembled beam unit is aligned with the end of the farthest steel beam assembly groove 303 of the vehicle body platform 1.

[0041] Step 12: Repeat steps 2 to 9 to transport the last beam unit to the steel beam direction adjustment plate 301, and adjust the position of the last beam unit so that it is first aligned with the left side assembly beam unit of the vehicle main platform 1, and connect the left side beam unit assembly to its left side through a bolt tightening mechanism, and then push the left side beam unit assembly as a whole to align with the right side beam unit assembly, and connect them through the bolt tightening mechanism, so that the left and right side beams are combined with the last beam unit to form a whole beam.

[0042] Step 13: The number of steel beam transport units in a composite beam can be determined based on actual needs, up to a maximum of five.

[0043] Step 15: Use the beam lifting system 4 to lift a whole beam onto the cap beam or auxiliary pier to complete the entire construction process.

[0044] Through process integration and equipment innovation, this invention achieves three major engineering benefits: construction period, material consumption, and work site requirements, thereby realizing a comprehensive improvement in construction efficiency, economy, and site intensiveness.
