Description

Technical Field

[0001] This invention relates to the field of bridge construction, and in particular to an integrated equipment and method for transporting and erecting large-size steel cap beams in confined spaces. Background Technology

[0002] In the reconstruction and expansion of urban expressways, the construction space is often limited due to the complex existing environment. On the one hand, construction requires the use of existing road passages, and temporary passages are often quite narrow. On the other hand, there are many height restrictions along the construction passages, such as existing road signs and traffic lights. In addition, the new bridges and roads are of a higher grade, and the piers that need to be installed are often large in size and have a large lifting capacity. Considering the above factors, the construction of high piers on urban expressways presents the following problems: (1) The construction space is limited and traditional equipment cannot be used for construction. For example, in the construction of prefabricated high piers, the high piers are often divided into several parts, such as the pier body and the cap beam. Each part needs to be transported from the back site to the installation position for hoisting. Due to the narrow construction passage, the beam transport vehicle and the hoisting equipment cannot work at the same time. If a truck crane is used, two cranes are often needed to lift the beam. In addition, the beam transport station position makes it impossible to expand the space. (2) The construction access occupies the existing urban road. The width of the access is limited. Often the width of the top cap beam is close to the width of the construction access. At the same time, it is affected by the height and traffic restrictions of the existing road. Traditional equipment cannot pass normally. For example, traditional gantry cranes will be blocked by the existing cap beam and road height restriction signs when they are running due to the limited width. (3) Safety issues: Since the hoisting construction is carried out next to the existing highway, it will pose potential risks to passing vehicles. For example, the gantry crane hoisting needs to meet the installation of the maximum height pier beam. If the equipment height is too high, it is easy to cause objects to fall from the sky. At the same time, it will visually interfere with passing vehicles and affect driving safety.

[0003] Therefore, it is necessary to invent a special equipment and erection method for transporting and installing large-size steel cap beams in confined spaces to meet construction needs. Summary of the Invention

[0004] The main objective of this invention is to provide an integrated equipment and method for transporting and erecting large-size steel cap beams in confined spaces, thereby solving the problems of limited construction space, narrow construction passages, height and traffic restrictions, complex component hoisting processes, and impacts on surrounding safety during the installation of high piers in urban expressway reconstruction and expansion projects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an integrated equipment for transporting and erecting large-size steel cap beams in confined spaces, including an erection trolley and a beam transport trolley; The erection trolley is equipped with at least two sliding and lifting first gantry mechanisms, each with a boom and multiple lifting mechanisms. The beam transport trolley is equipped with at least two sliding and liftable second gantry mechanisms. One end of the boom is hinged to the first gantry mechanism, and the lower end face of the other end is abutted and connected to the upper surface of the second gantry mechanism to form a gantry crane structure. A slewing mechanism is also provided in the middle of the beam transport trolley.

[0006] In the preferred embodiment, the first axle of the trolley passes through the lower part of the first gantry mechanism and is slidably connected to the first axle; Multiple sets of first traveling wheels are provided below the first gantry mechanism; The upper part of the first traveling wheel set is connected to the lower part of the first gantry mechanism through the wheel set steering mechanism. The first traveling wheel set is a hydraulic lifting wheel set. The installation structure of the second gantry mechanism and the second axle of the beam-carrying trolley is the same as that of the first gantry mechanism and the second axle of the erecting trolley.

[0007] In the preferred embodiment, the first gantry mechanism is further provided with a gantry traversing mechanism, which includes a traveling fixed base, a sliding rail on the first axle, the fixed base being slidably connected to the sliding rail, a plurality of first pin holes on the sliding rail, and a base cylinder inside the fixed base, the telescopic rod of the base cylinder being inserted into the first pin holes to fix the position of the fixed base. One side of the fixed base is hinged to one end of the traveling cylinder, and the other end of the traveling cylinder is hinged to the first gantry mechanism.

[0008] In the preferred embodiment, the first gantry mechanism and the second gantry mechanism have the same structure; The first gantry mechanism comprises multiple rectangular frame truss segments, and the four columns of the multiple truss segments are connected in succession to form the first gantry mechanism; The first gantry mechanism has multiple hydraulic cylinders installed inside its four columns or two of them, and the upper and lower ends of the multiple hydraulic cylinders are hinged to the upper and lower ends of the first gantry mechanism.

[0009] In the preferred embodiment, each truss segment is provided with multiple pin mechanisms, including a hydraulic pusher with a pin at the hydraulic pusher end, and multiple second pin holes on the column of the truss segment. The pin mechanism pushes the pin into the second pin hole of the previous truss segment to fix the overall position.

[0010] In the preferred embodiment, the top of the first gantry mechanism is hinged to one end of the boom via a boom slewing base. The boom slewing base is equipped with a drive device, which drives the boom to rotate.

[0011] In the preferred embodiment, the drive device includes a rotary motor, which is installed inside the boom slewing base and connected to the boom's rotating shaft.

[0012] In the preferred embodiment, the lifting mechanism is equipped with a horizontal movement motor, which is connected to the horizontal movement wheel of the lifting mechanism; The lifting mechanism's lifting pulley block is connected to the lifting device below, and the lifting device is connected to the lifting beam.

[0013] In the preferred embodiment, the lifting device has a rectangular frame structure, with the lifting beam passing through at least two lifting devices, and lifting bolts are provided at both ends of the lifting beam.

[0014] In the preferred embodiment, the slewing mechanism includes a rotating support platform, which is rotatably connected to the second axle. The second axle is also equipped with multiple slewing drive motors, each with its own output end. The outer ring of the rotating support platform is equipped with gears, and the slewing drive motors mesh with the outer ring of the rotating support platform.

[0015] In the preferred embodiment, the rotating bearing platform is also provided with protruding limiting blocks on both sides, and the inner side of the limiting blocks is provided with guide slopes.

[0016] The method includes: S1: Steel cap beam transportation. Adjust the distance between the front and rear gantry mechanisms on the beam transport trolley, retract the second gantry mechanism to the lowest height, and hoist and fix the steel cap beam onto the slewing mechanism in the middle of the beam transport trolley by a crane. Drive the second traveling wheel set to transport the steel cap beam to the installation position along the construction channel. S2: Steel cap beam rotation. After the beam transport trolley transports the steel cap beam to the installation position, the rotation mechanism is activated to rotate the steel cap beam 90°. S3: The two vehicles are combined. The erection trolley and the beam transport trolley are aligned and combined according to the hoisting position. The two vehicles are adjusted according to the chassis and position requirements, and the first and second traveling wheel sets are adjusted so that the erection trolley and the beam transport trolley reach their respective positions. Then the erection trolley rotates the boom. In order to avoid the erection and beam transport trolley from becoming unstable, the two booms are rotated and connected in sequence. The boom slewing base rotates to the top of the beam transport trolley. After adjusting the height of the first gantry mechanism / second gantry mechanism on both sides, the boom is connected so that the two trolleys are combined into two gantry structures in front and behind.

Move the gantry above the steel cap beam through the gantry lateral movement mechanism and sliding rail to facilitate hooking. Adjust the position of the hoisting mechanism, connect the lifting beam on the lifting device to the lifting lug of the steel cap beam, start the hoisting mechanism, lift and laterally move the steel cap beam, adjust the front and rear position of the steel cap beam through the drive wheel set, hoist the steel cap beam to the design position and connect and fix it.

[0017] This invention provides an integrated equipment and method for transporting and erecting large-size steel cap beams in confined spaces. By inventing a specialized integrated transport and erection equipment, large-size steel cap beams can be transported, rotated, and installed. The equipment adopts a split design, separating the movement and beam transport, and combining them for hoisting. This effectively avoids highway height and traffic restrictions. At the same time, the equipment is designed with a variable height structure, reducing its overall height during transport and over piers to improve its passability. During hoisting, the equipment height is adjusted in real time according to the installation height of the steel cap beam, improving construction efficiency while avoiding safety impacts on passing vehicles.

[0018] This invention develops specialized equipment and methods for pier and beam erection in complex environments during highway reconstruction and expansion. It aims to solve complex problems encountered in the installation of high piers during urban highway reconstruction and expansion, such as limited construction space, narrow construction access, height and traffic restrictions, complex component hoisting processes, and impacts on surrounding safety. Its specific beneficial effects are as follows: (1) The integrated transport and erection design is adopted, that is, the same set of equipment is used for transporting and erecting beams. At the same time, large-size steel cap beams can be rotated directly on the equipment, avoiding the use of multiple equipment for transporting and lifting beams, reducing the number of construction equipment used, and effectively solving the problem that multiple hoisting equipment cannot be positioned and deployed when the construction space is limited. (2) This equipment adopts a separable and combinable design, which solves the problem that traditional equipment cannot pass through narrow construction passages and height and traffic restrictions. When passing piers and height restriction frames, the equipment is split into independent trolleys and walks alternately on the upper and lower sections, effectively avoiding the existing construction passage height restriction frames. (3) This equipment is equipped with a variable height truss and pulley block lifting mechanism, which can adapt to the hoisting of steel cap beams at different installation heights. Compared with hydraulic gantry cranes, it has a wider range of adaptability and no limit on the minimum hoisting height. Compared with traditional gantry cranes, it effectively reduces the height of the hoisting equipment, especially the height of the equipment when traveling unloaded, which reduces safety risks and reduces the impact on the surrounding area of ​​existing highways.

Detailed Implementation

[0021] Example 1 like Figures 1-9 As shown, an integrated equipment for transporting and erecting large-size steel cap beams in confined spaces includes an erection trolley 100 and a beam transport trolley 200. The trolley 100 is equipped with at least two sliding and lifting first gantry mechanisms 110, the first gantry mechanism 110 is equipped with a boom 130, and the boom 130 is equipped with multiple lifting mechanisms 150. The beam transport trolley 200 is provided with at least two sliding and liftable second gantry mechanisms 210. One end of the boom 130 is hinged to the first gantry mechanism 110, and the lower end face of the other end is abutted and connected to the upper surface of the second gantry mechanism 210 to form a gantry crane structure. A slewing mechanism 230 is also provided in the middle of the beam transport trolley 200.

[0022] An integrated equipment for transporting and erecting large-size steel cap beams in confined spaces includes an erection trolley 100 and a beam transport trolley 200. The erection trolley 100 is equipped with at least two sliding and lifting first gantry mechanisms 110, each with a boom 130 mounted on it and multiple lifting mechanisms 150 mounted thereon. The beam transport trolley 200 is equipped with at least two sliding and lifting second gantry mechanisms 210. One end of the boom 130 is hinged to the first gantry mechanism 110, and the lower end face of the other end is abutted against the upper surface of the second gantry mechanism 210, together forming a gantry crane structure. The beam transport trolley 200 is also equipped with a slewing mechanism 230 in the middle.

[0023] In use, the steel cap beam is first carried by the slewing mechanism 230 of the beam transport trolley 200. The position is adjusted by the sliding and lifting functions of the second gantry mechanism 210 to meet the transportation requirements and transport the steel cap beam to the installation area. After arriving at the position, the first gantry mechanism 110 of the erection trolley 100 slides and lifts, and cooperates with the hinge rotation of the boom 130 to make the boom 130 and the second gantry mechanism 210 abut against each other to form a gantry crane structure. Then, the hoisting mechanism 150 is operated to hoist the steel cap beam. After the installation is completed, the first gantry mechanism 110 and the second gantry mechanism 210 are separated to prepare for the next transportation and erection.

[0024] In the preferred embodiment, the first axle 120 of the trolley 100 passes through the lower part of the first gantry mechanism 110 and is slidably connected to the first axle 120; Multiple sets of first traveling wheel sets 112 are provided below the first gantry mechanism 110; The upper part of the first traveling wheel set 112 is connected to the lower part of the first gantry mechanism 110 through the wheel set steering mechanism 116. The first traveling wheel set 112 is a hydraulic lifting wheel set. The installation structure of the second gantry mechanism 210 and the second axle 220 of the beam transport trolley 200 is the same as that of the first gantry mechanism 110 and the second axle 220 of the erection trolley 100, such as... Figure 2 As shown.

[0025] The first axle 120 of the erecting trolley 100 passes through the lower part of the first gantry mechanism 110 and is slidably connected to it. Multiple sets of first traveling wheel sets 112 are provided below the first gantry mechanism 110. The upper part of the first traveling wheel sets 112 is connected to the lower part of the first gantry mechanism 110 through the wheel set steering mechanism 116, and is a hydraulic lifting wheel set. The installation structure of the second gantry mechanism 210 and the second axle 220 of the beam transport trolley 200 is the same as the installation structure of the first gantry mechanism 110 and the first axle 120 of the erecting trolley 100.

[0026] In use, the position of the first gantry mechanism 110 on the erection trolley 100 can be adjusted by the sliding connection between the first axle 120 and the first gantry mechanism 110. The first traveling wheel set 112 adjusts the height of the erection trolley 100 through the hydraulic lifting function. The wheel set steering mechanism 116 realizes the flexible change of the traveling direction. The second gantry mechanism 210 and the second axle 220 adopt the same installation structure and have the same sliding, lifting and steering functions as the first gantry mechanism 110 and the first axle 120, which facilitates the flexible adjustment of the beam transport trolley 200.

[0027] This structural design allows the erection trolley 100 and the beam transport trolley 200 to have good mobility, steering and height adjustment capabilities in confined spaces. The hydraulic lifting function of the first traveling wheel set 112 can adapt to different ground conditions. The wheel set steering mechanism 116 improves the equipment's steering flexibility. The same installation structure simplifies the manufacturing and maintenance process, and overall improves the equipment's adaptability and operational efficiency in complex environments.

[0028] In the preferred embodiment, the first gantry mechanism 110 is further provided with a gantry traversing mechanism 113. The gantry traversing mechanism 113 includes a traveling fixed base 1131, and a sliding rail 213 is provided on the first axle 120. The fixed base 1131 is slidably connected to the sliding rail 213. The sliding rail 213 is provided with a plurality of first pin holes 214. The fixed base 1131 is provided with a base cylinder 1133 inside. The telescopic rod of the base cylinder 1133 is inserted into the first pin holes 214 to fix the position of the fixed base 1131. One side of the fixed base 1131 is hinged to one end of the traveling cylinder 1132, and the other end of the traveling cylinder 1132 is hinged to the first gantry mechanism 110.

[0029] The first gantry mechanism 110 is provided with a gantry lateral movement mechanism 113, which includes a traveling fixed base 1131 and a sliding rail 213 on the first axle 120. The fixed base 1131 is slidably connected to the sliding rail 213. The sliding rail 213 has multiple first pin holes 214. The telescopic rod of the base cylinder 1133 inside the fixed base 1131 can be inserted into the first pin holes 214 to fix the position of the base 1131. One side of the fixed base 1131 is hinged to one end of the traveling cylinder 1132, and the other end of the traveling cylinder 1132 is hinged to the first gantry mechanism 110.

[0030] In use, the base cylinder 1133 of the fixed base 1131 is first inserted into the first pin hole 214 of the sliding rail 213 for fixation. Then, the first traveling wheel set 112 driven by electric retraction or pushing moves on the first axle 120. The two first gantry mechanisms 110 on the first axle 120 move individually, that is, when one first gantry mechanism 110 moves, the other remains stationary.

[0031] This structure achieves precise lateral movement and fixation of the first gantry mechanism 110 through the gantry lateral movement mechanism 113, while the travel cylinder 1132 provides stable driving force. The single movement method makes operation more flexible and can adapt to the fine-tuning needs of confined spaces. The electrically driven first travel wheel set 112 improves movement efficiency and control precision, and as a whole, it enhances the equipment's adaptability and operational stability in complex environments. At the same time, it simplifies the adjustment process and improves work efficiency.

[0032] In the preferred embodiment, the first gantry mechanism 110 and the second gantry mechanism 210 have the same structure; The first gantry mechanism 110 includes multiple rectangular frame truss segments 111, and the four columns of the multiple truss segments 111 are connected in a step-by-step manner to form the first gantry mechanism 110. The first gantry mechanism 110 has four columns or two of them equipped with multi-stage hydraulic cylinders 115 inside, and the upper and lower ends of the multi-stage hydraulic cylinders 115 are hinged to the upper and lower ends of the first gantry mechanism 110.

[0033] The first gantry mechanism 110 and the second gantry mechanism 210 have the same structure, both consisting of multiple rectangular frame truss segments 111. The four columns of the multiple truss segments 111 are connected in stages to form the main body of the gantry. The four columns of the first gantry mechanism 110 or two of the columns are equipped with multi-stage hydraulic cylinders 115. The upper and lower ends of the multi-stage hydraulic cylinders 115 are respectively hinged to the upper and lower ends of the first gantry mechanism 110.

[0034] like Figure 3 As shown, by controlling the extension and retraction of the multi-stage hydraulic cylinders 115, the columns of the truss segments 111 can be driven to extend or retract along the splicing direction, realizing the height adjustment of the first gantry mechanism 110 and the second gantry mechanism 210, meeting the height requirements under different operating scenarios. In this structural design, the step-by-step splicing of the truss segments 111 ensures the structural strength and stability of the gantry mechanism, while the multi-stage hydraulic cylinders 115 provide stable lifting power, making the gantry height adjustment precise and efficient. The identical structure of the first gantry mechanism 110 and the second gantry mechanism 210 simplifies the manufacturing process and maintenance procedures, while enhancing the versatility of the equipment. It can better adapt to the diverse needs of transporting and erecting large-size steel cap beams in confined spaces, improving overall operating efficiency.

[0035] In the preferred embodiment, each truss segment 111 is provided with multiple pin mechanisms 114. The pin mechanism 114 includes a hydraulic pusher, and the hydraulic pusher end is provided with a pin. The column of the truss segment 111 is provided with multiple second pin holes 117. The pin mechanism 114 pushes the pin into the second pin hole 117 of the previous truss segment 111 to fix the position of the whole.

[0036] Each truss segment 111 is provided with multiple pin mechanisms 114. The pin mechanism 114 includes a hydraulic jacking device, the jacking end of which is equipped with a pin, and multiple second pin holes 117 are opened on the column of the truss segment 111.

[0037] In use, after the truss segment 111 is adjusted to the required height by the multi-stage hydraulic cylinder 115, the hydraulic jacking device of the pin mechanism 114 pushes the pin into the second pin hole 117 of the previous truss segment 111, thereby fixing the position of the entire gantry mechanism. This structure, through the cooperation of the pin mechanism 114 and the second pin hole 117, can achieve a stable lock after the gantry mechanism is adjusted to the appropriate height. The hydraulic jacking drive ensures the accuracy and reliability of the pin action. The setting of multiple pin mechanisms 114 and second pin holes 117 enhances the overall fixing effect, effectively preventing the gantry mechanism from shifting or shaking during operation, improving the structural stability and operational safety of the equipment, and also facilitating flexible adjustment and quick fixing of the gantry height according to different operational needs, thus improving operational efficiency.

[0038] In the preferred embodiment, the top of the first gantry mechanism 110 is hinged to one end of the boom 130 via the boom slewing base 140. The boom slewing base 140 is equipped with a drive device, which drives the boom 130 to rotate by an angle.

[0039] The drive unit includes a rotary motor 141, which is installed inside the boom slewing base 140 and is connected to the rotating shaft of the boom 130.

[0040] The top of the first gantry mechanism 110 is hinged to one end of the boom 130 via the boom slewing base 140. The boom slewing base 140 is equipped with a drive device, which includes a rotary motor 141. The rotary motor 141 is located inside the boom slewing base 140 and connected to the rotation shaft of the boom 130, and can drive the boom 130 to rotate.

[0041] In use, the rotary motor 141 inside the boom slewing base 140 is started. Its connection to the boom 130's rotation shaft drives the boom 130 to rotate, thereby adjusting the boom 130's angle and position to adapt to different operational needs. For example, when two vehicles are combined, it enables precise docking of the boom 130 with the second gantry mechanism 210. In this structure, the hinged design between the boom slewing base 140 and the boom 130 provides a base for the boom 130's rotation. The rotary motor 141, as a drive device, can precisely control the boom 130's rotation angle, improving the flexibility and accuracy of boom 130 operation. This allows the equipment to flexibly adjust the boom 130's position even in confined spaces, better completing lifting and docking operations. Simultaneously, the motor drive provides rapid response, contributing to improved overall operational efficiency.

[0042] In the preferred embodiment, the lifting mechanism 150 is equipped with a transverse motor, which is connected to the transverse wheel of the lifting mechanism 150; The lifting pulley block 151 of the lifting mechanism 150 is connected to the lifting device 152 below, and the lifting device 152 is connected to the lifting beam 153.

[0043] The lifting device 152 has a rectangular frame structure, and the lifting beam 153 passes through at least two lifting devices 152. The lifting beam 153 is equipped with lifting bolts 154 at both ends.

[0044] The lifting mechanism 150 is equipped with a transverse motor, which is connected to the transverse wheel of the lifting mechanism 150. The lifting pulley block 151 of the lifting mechanism 150 is connected to the lifting device 152 below, and the lifting device 152 is connected to the lifting beam 153. The lifting device 152 is a rectangular frame structure, and the lifting beam 153 passes through at least two lifting devices 152. The lifting beam 153 is equipped with lifting bolts 154 at both ends.

[0045] In use, first, based on the lifting point position of the steel cap beam, start the lateral movement motor on the lifting mechanism 150. The lateral movement motor drives the lateral movement wheel to rotate, adjusting the lateral position of the lifting mechanism 150 so that the lifting device 152 and the lifting beam 153 are aligned with the lifting lugs of the steel cap beam. Then, connect and fix the lifting bolts 154 at both ends of the lifting beam 153 to the lifting lugs of the steel cap beam. Then, through the extension and retraction of the lifting pulley block 151 of the lifting mechanism 150, drive the lifting device 152, the lifting beam 153 and the steel cap beam to rise and fall synchronously, completing the lifting operation of the steel cap beam.

[0046] In this structure, the cooperation between the lateral motor and the lateral wheel gives the lifting mechanism 150 the ability to make fine adjustments laterally, which can accurately align with the lifting point. The rectangular frame structure of the lifting device 152, together with the lifting beam 153 that passes through multiple lifting devices, can stably support the large-sized steel cap beam. The lifting bolts 154 ensure that the steel cap beam and the lifting beam 153 are firmly connected. The overall design improves the stability and accuracy of the steel cap beam lifting, adapts to the lifting needs of large-sized steel cap beams in confined spaces, and is easy to operate, which helps to improve work efficiency.

[0047] In the preferred embodiment, the slewing mechanism 230 includes a rotating support platform 231, which is rotatably connected to the second axle 220. The second axle 220 is also provided with a plurality of slewing drive motors 233, the output end of which is provided with a slewing drive motor 233. The outer ring of the rotating support platform 231 is provided with a gear, and the slewing drive motors 233 mesh with the outer ring of the rotating support platform 231.

[0048] The rotating support platform 231 is also provided with protruding limiting blocks 232 on both sides, and the inner side of the limiting blocks 232 is provided with guide slope.

[0049] like Figure 4As shown, the slewing mechanism 230 includes a rotating support platform 231, which is rotatably connected to the second axle 220. The second axle 220 is also equipped with multiple slewing drive motors 233. The output end of the slewing drive motors 233 is equipped with drive gears. The outer ring of the rotating support platform 231 is equipped with gears. The drive gears of the slewing drive motors 233 mesh with the gears on the outer ring of the rotating support platform 231. The rotating support platform 231 has protruding limiting blocks 232 on both sides. The inner side of the limiting block 232 has a guide slope, which can guide the steel cap beam into the rotating support platform 231.

[0050] In use, when the steel cap beam is hoisted to the slewing mechanism 230 of the beam transport trolley 200, the steel cap beam will slide along the guide slope inside the limiting block 232 and accurately enter the rotating bearing platform 231. The limiting block 232 also limits the steel cap beam to prevent it from shifting during transportation. When it is necessary to adjust the angle of the steel cap beam, the slewing drive motor 233 on the second axle 220 is started. Through the meshing transmission between the drive gear and the outer ring gear of the rotating bearing platform 231, the rotating bearing platform 231 is driven to rotate around the second axle 220, thereby driving the steel cap beam to rotate synchronously to the required angle to adapt to subsequent installation requirements.

[0051] In this structure, the guide ramp limiting block 232 simplifies the alignment and placement of the steel cap beam, improving the accuracy and efficiency of its placement. The rotary drive motor 233 and gear meshing transmission design can stably and accurately control the rotation angle of the rotating bearing platform 231, ensuring a smooth rotation process for the steel cap beam. This adapts to the needs of transporting and adjusting the angle of the steel cap beam in confined spaces. At the same time, the rotational connection between the rotating bearing platform 231 and the second axle 220 further ensures the flexibility of the rotation operation, and overall improves the convenience and stability of the equipment for transporting and adjusting the angle of the steel cap beam.

[0052] Example 2 Further explanation in conjunction with Example 1, such as Figure 1-9 As shown in the structure, S1: Steel cap beam transportation. Adjusting the distance between the front and rear gantry mechanisms on the beam transport trolley 200, the second gantry mechanism 210 is retracted to its lowest height. The steel cap beam is then hoisted and fixed onto the slewing mechanism 230 in the middle of the beam transport trolley 200 by a crane. The second traveling wheel set 212 is then driven to transport the steel cap beam along the construction channel to the installation position. Figure 5 As shown; S2: After the steel cap beam is transported to the installation position by the beam transport trolley 200, the rotation mechanism 230 is activated to rotate the steel cap beam 90°. Figure 6 As shown; S3: The two vehicles are combined. The erection trolley 100 and the beam transport trolley 200 are aligned and combined according to the hoisting position. Based on the chassis and positioning requirements, the first and second travel wheel sets 112 and 212 are adjusted to ensure the erection trolley 100 and beam transport trolley 200 reach their respective positions. Then, the erection trolley 100 rotates the boom 130. To prevent instability of the erection and beam transport trolley 100, the two booms 130 are rotated and connected sequentially. The boom slewing base 140 rotates above the beam transport trolley 200. After adjusting the height of the first gantry mechanism 110 and the second gantry mechanism 210 on both sides, the booms 130 are connected, so that the two trolleys combine to form a front and rear gantry structure. Figure 7 As shown; S4: Steel cap beam hoisting. Adjust the four gantry mechanisms on both sides to the appropriate height according to the installation height of the steel cap beam, and fix them with pin mechanisms 114. Move the gantry above the steel cap beam using the gantry lateral movement mechanism 113 and sliding rail 213 for easy hooking. Adjust the position of the lifting mechanism 150, connect the lifting beam 153 on the lifting device 152 to the lifting lugs of the steel cap beam, start the lifting mechanism 150, lift and laterally move the steel cap beam, and adjust the front and rear position of the steel cap beam using the drive wheel set. Hoist the steel cap beam to the designed position and connect and fix it. The steel cap beam installation is complete. Figure 8 , Figure 9 As shown; S5: Separate the equipment, open the connection of the boom 130 of the front and rear combined gantry, rotate the boom 130 in sequence to separate the combined trolley, the erection trolley 100 moves forward to the next installation position, and the beam transport trolley 200 moves back to transport the next steel cap beam, repeating S1~S5.
