[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a beam transport and lifting device, comprising a beam transport section 1, a beam lifting and unloading section 2, an extended lifting platform 3, an electric hoist 4, a traveling motor 5, a lifting hook 6, and a connecting lifting longitudinal beam 7. The extended lifting platform is located at the front end of the beam transport section, and the beam lifting and unloading section is located at the rear end of the beam transport section. The beam transport section and the beam lifting and unloading section are connected by the connecting lifting longitudinal beam. The beam transport section can be opened to facilitate the placement of the box girder onto the support frame by a crane. The beam transport section can also utilize the extended lifting platform to complete the beam loading itself. This beam transport and lifting device is made of high-strength aluminum, and the components are bolted together, allowing for rapid on-site assembly.

[0031] The beam transport section includes a support frame 11, an upper frame 12, and a first hoisting longitudinal beam 13. The support frame includes a base 111 and a support plate 112. There are two bases, and the two bases support the support plate. There are two upper frames, and the two upper frames are fixedly installed on the two bases by bolts.

[0032] The two chassis include a first chassis and a second chassis, which have identical structures. Each chassis includes a main crossbeam 1111 and two axles 1112. Axle mounting seats 1113 are provided on both sides of the main crossbeam. The axle mounting seats are fixed to both sides of the main crossbeam by welding, with two axle mounting seats symmetrically welded on each side. A bearing mounting seat is provided below the axle mounting seat, and a ball bearing is fixedly mounted on the bearing mounting seat. The outer ring of the ball bearing is fixedly fitted with the bearing mounting seat, and the axle passes through the inner ring of the ball bearing. The chassis is fixedly installed on the axle mounting seat, and the axle can rotate freely around its own central axis. A train wheel 1114 is fixedly installed at each end of the axle. The four train wheels of the chassis support the chassis and can stand independently on the railway rails. The chassis is also provided with a load-bearing universal ball joint 1115 and a slewing support 1116. The slewing support is located in the middle of the chassis, and two load-bearing universal ball joints are arranged side by side on each side of the slewing support. The load-bearing universal ball joints and the slewing support are used to install the load-bearing plate. The chassis is also provided with a chassis connecting seat 1117.

[0033] The bearing plate has an "I" shaped structure, including two connecting seats 1121 and one connecting longitudinal beam 1122. The two ends of the connecting longitudinal beam are connected to the two connecting seats by bolts, which facilitates disassembly and assembly on the construction site. The two connecting seats are connected to the first chassis and the second chassis by bearing universal ball joints and slewing supports, respectively. There are two upper frames, which are a first upper frame connected to the first chassis and a second upper frame connected to the second chassis. The two upper frames have the same structure. The upper frame includes a portal frame beam 121. A lifting hook mounting hole 122 is provided directly above the portal frame beam, and a longitudinal beam connecting seat 123 is provided directly below the portal frame beam. The lifting hook is fixedly installed on the upper frame by bolts that fit with the lifting hook mounting hole. The lifting hook is used to assemble the first lifting longitudinal beam. The lifting hook is equipped with a fixed pulley at its end, and a rope passes through the pulley. One end of the rope can be connected to the first lifting longitudinal beam on the ground, and the other end can be pulled by personnel on the ground, thus lifting the first lifting longitudinal beam to the installation position. The extended lifting platform is fixedly connected to the front end of the first upper frame by bolts to the longitudinal beam connecting seat. The two ends of the first lifting longitudinal beam are connected to the longitudinal beam connecting seats of the two upper frames through an intermediate connecting rod and a rotating shaft to form a flexible connection. An upper frame connecting seat 124 is also provided at the lower end of the upper frame. The flexible connection between the first lifting longitudinal beam and the two upper frames and the flexible connection between the bearing plate and the two chassis together form a steering connection, which can ensure that the entire mechanism does not jam when traveling on the turning rail. The two chassis are respectively connected to the two upper frames by bolts. When it is necessary to use an off-line crane to lift the box girder onto the rail, the upper frame can be removed from the chassis, and only the bearing frame part is placed on the railway track. A travel motor is also fixedly installed on the main crossbeam of the first chassis. A main pulley is fixedly installed on the output shaft end of the machine, and a driven pulley is fixedly installed on the axle at the front end of the first chassis. The main pulley and the driven pulley are connected by a belt. The traveling motor can drive the axle at the front end of the first chassis to rotate. The traveling motor is speed-adjustable and can rotate in both directions. It is driven by a small generator, and the traveling speed can be adjusted arbitrarily between 0-15km / h. The forward or reverse rotation of the traveling motor drives the axle at the front end of the first chassis to rotate in both directions, so that the beam transport and lifting equipment moves forward or backward. The beam lifting and unloading section includes an open trapezoidal frame 21, a second lifting longitudinal beam 22, a third chassis 23, and a third upper frame 24. The beam lifting and unloading section is assembled on-site. It only needs to install the lifting longitudinal beam into place using a lifting hook. The second lifting longitudinal beam is connected to the rear end of the open trapezoidal frame and the front end of the third upper frame, respectively. The two ends of the connecting lifting longitudinal beam are connected to the rear end of the second upper frame and the front end of the open trapezoidal frame, respectively, connecting the beam transport section and the beam lifting and unloading section.

[0034] The specific work process is as follows:

[0035] (1) First, place two chassis on the railway track, with the train wheels of the chassis in contact with the rails. Then, install a bearing plate on the two chassis. The bearing plate is connected to the two chassis by a rotating shaft. The two chassis and one bearing plate are combined into an integral bearing frame to undertake the function of transporting box girders.

[0036] (2) When there is an external crane, the box girder is hoisted onto the support frame by the external crane;

[0037] (3) Install the upper frame and fix the two upper frames to the two chassis respectively with bolts;

[0038] (4) Install the first hoisting longitudinal beam. Use an A-frame ladder to install the hoisting hook to the upper frame and tighten it with bolts in the hoisting hook installation hole. The end of the hoisting hook is equipped with a fixed pulley. The rope passes through the fixed pulley, one end is connected to the first hoisting longitudinal beam on the ground, and the other end is pulled by the personnel on the ground. In this way, the first hoisting longitudinal beam is lifted to the installation position. Then, the personnel on the A-frame ladder assist in placing the first hoisting longitudinal beam in place and install the first hoisting longitudinal beam in place through the intermediate connecting rod and the rotating shaft. In this way, the process of installing the beam with the help of an external crane is completed.

[0039] (5) When no external crane is available, after assembling the support frame, assemble the upper frame and the first lifting longitudinal beam according to the method described in step (4), and install the extended lifting platform and two electric hoists. The beam transport section can then feed the beam by itself: first, use the first electric hoist to lift the head of the box girder and move it into the beam transport section; then the first electric hoist returns to the extended lifting platform to lift the tail of the box girder, and the second electric hoist lifts the head of the box girder, continuing to feed the beam inward until the box girder reaches the middle position of the beam transport section. At this time, place the box girder on the support frame to complete the entire beam lifting operation.

[0040] (6) When the construction pit is cleared and the beam needs to be erected, the assembled open trapezoidal beam is first placed on the construction site, and the corresponding sleepers are placed at the placement position. The third base and the third upper frame are then assembled behind it. The second hoisting longitudinal beam is installed in the same way as the first hoisting longitudinal beam. After the second hoisting longitudinal beam is installed, the height adjustment structure of the open trapezoidal frame is adjusted to keep the newly installed longitudinal beam horizontal.

[0041] (7) Install the connecting hoisting longitudinal beam, control the traveling motor to move the beam transport section to the front of the beam unloading section, and install the connecting hoisting longitudinal beam in the same way as the first hoisting longitudinal beam. After the connecting hoisting longitudinal beam is installed, operate the electric hoist to lift the box beam and move along the first hoisting longitudinal beam, the connecting hoisting longitudinal beam, and the second hoisting longitudinal beam to transport the box beam to the designated location and lower the box beam to the designated position to complete the beam unloading. The two electric hoists can be operated separately or combined into a whole and operated synchronously. The operation mode adopts wireless remote control.
