Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road and bridge construction, and particularly relates to a method and device for carrying a steel beam through a hole by using multiple remote-controlled three-dimensional hydraulic power trolleys. BACKGROUND

[0002] In the prior art, many workers are required, and the safety risk is large, so how to safely, quickly and efficiently build a bridge across a highway, a railway, a river, a valley and other obstacles has become a technical problem in current construction.

[0003] Chinese patent CN202210818533.5 discloses a rail-cable type beam carrying system and construction method for installing a main beam of a valley-crossing steel arch bridge, which comprises a rail-cable system, a beam carrying vehicle and a traction system. The rail-cable system uses a load-bearing cable as a beam carrying vehicle track. A winch is used to pull the beam carrying vehicle along the load-bearing cable at one end of the bridge, so as to transport the main beam segment to a position below the installation position. During the movement of the beam carrying vehicle, the winch provides a certain counter-tension, so that the connecting steel wire rope between the two beam carrying vehicles is always in a stressed state. A continuous jack is arranged at the anchoring end of each main beam permanent sling and arch rib, and each continuous jack synchronously lifts the main beam segment to the installation position. Chinese patent CN201610432466.8 discloses a method for cross-bridge construction by using a tire-type carrier. The tire-type carrier is used to realize functions such as in-site beam moving and box beam cross-bridge loading.

[0004] Therefore, in the prior art, it is difficult to use a carrier to transport a large-span bridge, and the construction cost is increased. When a beam carrying vehicle is used for transportation, the running path of the beam carrying vehicle is long and the bridge to be installed cannot be quickly installed due to the curvature of the bridge to be installed and the beam body.

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of the present application.

[0044] S1, installing a support at a bridge site, installing a Bailey frame and a steel rail on the upper surface of the support, the steel rail being located on the upper surface of the Bailey frame, a hydraulic lifting portal and a plurality of three-dimensional hydraulic power trolleys being installed on the upper surface of the steel rail, the Bailey frame and the steel rail being used for the plurality of three-dimensional hydraulic power trolleys to travel;

[0045] S2, sequentially connecting a to-be-installed segmental steel beam and a steel guide beam and placing the to-be-installed segmental steel beam and the steel guide beam on the plurality of three-dimensional hydraulic power trolleys and the hydraulic lifting portal to form a whole-hole steel beam to be carried;

[0046] S3, remotely controlling the plurality of three-dimensional hydraulic power trolleys to jacking and carrying the whole-hole steel beam to be carried to move in a first direction; the first direction is the direction in which the whole-hole steel beam to be carried is installed;

[0047] S4, after the plurality of three-dimensional hydraulic power trolleys move a preset distance in the first direction, the hydraulic lifting portal jacks up and supports the whole-hole steel beam to be carried, wherein a three-dimensional hydraulic power trolley of the plurality of three-dimensional hydraulic power trolleys that is close to the hydraulic lifting portal is separated from the whole-hole steel beam to be carried and returns to an initial position;

[0048] S5, repeating steps S3 and S4 until the whole-hole steel beam to be carried reaches a designated installation position.

[0049] In the embodiments of the present application, the three-dimensional hydraulic power trolleys can travel on the steel rail of the Bailey frame, the three-dimensional hydraulic power trolleys are sequentially placed under the whole-hole steel beam to be carried, the whole-hole steel beam to be carried is jacked up and carried by the plurality of three-dimensional hydraulic power trolleys to move in a first direction, the hydraulic lifting portal is jacked up and supports the whole-hole steel beam to be carried after moving a preset distance, the three-dimensional hydraulic power trolley is separated from the whole-hole steel beam to be carried and returns to an initial position, the whole-hole steel beam to be carried is jacked up again, and the step is repeated until the whole-hole steel beam to be carried reaches a designated position. The three-dimensional hydraulic power trolleys are used to jack up and carry the whole-hole steel beam to be carried, which does not need manual jacking, improves the safety of the steel beam passing through the hole, and the three-dimensional hydraulic power trolleys are used to reciprocate under the whole-hole steel beam to be carried, thereby transporting the whole-hole steel beam to be carried in segments, which improves the efficiency of the steel beam passing through the hole and reduces production costs.

[0050] As a preferred embodiment of the present application, step S5 specifically includes:

[0051] Repeat steps S3 and S4. After the steel guide beam and the steel beam segment to be installed near the steel guide beam have passed through the hole, remove the steel guide beam.

[0052] The three-dimensional hydraulic power trolley carries the steel beam segments to be installed to the designated installation position.

[0053] Understandably, the three-dimensional hydraulic power trolley lifts the entire steel beam to be transported to a preset height and moves it along a first direction. When the trolley approaches the hydraulic lifting gantry, it decelerates and stops. At this time, the hydraulic lifting gantry rises and supports the steel beam. The trolley then falls back and detaches from the beam, moving in the opposite direction. This process is repeated until the steel guide beam and the adjacent steel segment have passed through the hole. The guide beam is then removed, and the trolley transports the remaining steel segment to the designated position. By using the reciprocating motion of the trolley on the rails to transport the beam, the trolley's path is unaffected by the beam's curvature, preventing it from taking detours and reducing transport time and cost.

[0054] The height to which the bridge can be lifted by the three-dimensional hydraulic power trolley can be set according to the elastic device on the three-dimensional hydraulic power trolley and actual needs, and this application does not limit this. For example, when the elastic range of the elastic device of the three-dimensional hydraulic power trolley is 20 mm, the three-dimensional hydraulic power trolley can lift the whole steel beam to be transported by 20 mm.

[0055] like Figure 2 As shown, on the other hand, the multi-remote-controlled three-dimensional hydraulic power trolley steel beam conveying device of this application includes a support 1, a Bailey bridge 2 and steel rails, a three-dimensional hydraulic power trolley, a hydraulic lifting gantry 4, and a whole-hole steel beam to be conveyed and a steel guide beam. The support 1 supports the Bailey bridge 2; the Bailey bridge 2 is located on top of the support 1, and steel rails are provided on top of the Bailey bridge 2 for the three-dimensional hydraulic power trolley to travel on; the three-dimensional hydraulic power trolley is remotely powered to lift and convey the whole-hole steel beam to be conveyed along a first direction; the first direction is the direction in which the whole-hole steel beam to be conveyed is installed; the hydraulic lifting gantry 4 is located at the front end of the three-dimensional hydraulic power trolley in the first direction and is used to lift and support the whole-hole steel beam to be conveyed.

[0056] As a preferred embodiment of this application, the whole-span steel beam to be transported includes a steel guide beam and a plurality of steel beam segments to be installed. The plurality of steel beam segments to be installed are connected sequentially, and the steel guide beam is connected to the installation steel beam to form the whole-span steel beam to be transported. The steel guide beam is located at the front end of the whole-span steel beam to be transported in a first direction.

[0057] It is understandable that steel guide beams are installed at the front end of several steel beam segments to be installed in the first direction to ensure the spacing and stability of the installed steel beams. After the steel beam segments to be installed connected to the steel guide beams have passed through the holes, the steel guide beams can be removed.

[0058] In a preferred embodiment of this application, the integral steel beam to be transported is further provided with a counterweight section. The counterweight section is located at the end of the integral steel beam to be transported in the first direction and is connected to the segment steel beam to be installed. The counterweight section is used to increase the overturning resistance of the integral steel beam to be transported and improve the safety of transport.

[0059] It is understandable that a counterweight section can be set according to actual usage needs. Whether or not a counterweight section is set on the whole steel beam to be transported does not affect the operation of the multiple remote-controlled three-dimensional hydraulic power trolleys transporting steel beams through the hole.

[0060] like Figure 3 As shown in the preferred embodiment of this application, the three-dimensional hydraulic power trolley includes a vehicle body 31 and a three-dimensional hydraulic jack 32, wherein the vehicle body 31 is used to drive the whole-hole steel beam to be transported to move along a first direction; the three-dimensional hydraulic jack 32 is used to lift the whole-hole steel beam to be transported.

[0061] When the three-dimensional hydraulic power trolley carries the whole-span steel beam to be carried, the three-dimensional hydraulic jack 32 is first used to lift the whole-span steel beam to be carried to a preset height. Then, the trolley body 31 drives the three-dimensional hydraulic jack 32 and the whole-span steel beam to be carried to move along the first direction. When the three-dimensional hydraulic power trolley approaches the hydraulic lifting gantry 4, the trolley body 31 decelerates and stops, the hydraulic lifting gantry rises to support the whole-span steel beam to be carried, the three-dimensional hydraulic jack 32 descends, and moves in the opposite direction of the first direction to return to the initial position.

[0062] In a preferred embodiment of this application, the vehicle body 31 is provided with mounting holes, and the three-dimensional hydraulic jack 32 is engaged with the vehicle body 31 through the mounting holes.

[0063] Understandably, the three-dimensional hydraulic jack 32 is connected to the vehicle body 31 through the mounting hole to prevent the three-dimensional hydraulic jack 32 from shifting during the process of carrying the whole steel beam to be carried through the hole, which would affect the installation of the whole steel beam to be carried.

[0064] As a preferred embodiment of this application, the three-dimensional hydraulic power trolley further includes X, Y, and Z three-way hydraulic cylinders.

[0065] The X, Y, and Z three-way hydraulic cylinders are located in the middle of the three-dimensional hydraulic power trolley and are used to precisely adjust the position of the whole-hole steel beam to be transported in the X, Y, and Z directions.

[0066] Understandably, when the whole steel beam to be transported by the three-dimensional hydraulic power trolley is heavy, X, Y, and Z three-way cylinders can be installed at one end of the three-dimensional hydraulic power trolley to provide power to the three-dimensional hydraulic power trolley; alternatively, the X, Y, and Z three-way cylinders can be installed on land and connected to the three-dimensional hydraulic power trolley and cylinders through pipelines.

[0067] In a preferred embodiment of this application, the rail is further provided with a stop and a limit switch. The stop is located at the front end of the rail in the first direction and is used to prevent the three-dimensional hydraulic power trolley from moving the whole-span steel beam to be transported in the first direction. The limit switch is located on the side of the stop close to the hydraulic lifting gantry. When the distance between the limit switch and the three-dimensional hydraulic power trolley is less than a preset value, the three-dimensional hydraulic power trolley decelerates and stops moving, the hydraulic lifting gantry lifts and supports the whole-span steel beam to be transported, and the three-dimensional hydraulic power trolley disengages from the whole-span steel beam to be transported and returns to its initial position.

[0068] The distance between the limit switch and the hydraulic lifting gantry 4 can be set according to actual needs, and this application does not impose specific restrictions on this.

[0069] Understandably, when the distance between the limit switch and the three-dimensional hydraulic power trolley is less than the preset value, it is considered that the distance between the three-dimensional hydraulic power trolley and the limit switch is too small. The speed of the three-dimensional hydraulic power trolley should be slowed down. If the three-dimensional hydraulic trolley cannot stop completely, a stop should be used to prevent the three-dimensional hydraulic trolley from continuing to carry the whole hole steel beam to be carried along the first direction. At this time, the hydraulic lifting gantry 4 should be raised to support the whole hole steel beam to be carried, so that the three-dimensional hydraulic power trolley can be lowered and detached from the steel frame to be carried.

[0070] As a preferred embodiment of this application, the three-dimensional hydraulic power trolley further includes a reduction gearbox 33 and a frequency-modulated motor 34. The reduction gearbox 33 is located at one end of the three-dimensional hydraulic power trolley and is used to adjust the speed of the three-dimensional hydraulic power trolley. The frequency-modulated motor 34 is located at the end of the three-dimensional hydraulic power trolley away from the reduction gearbox 33 and is connected to the reduction gearbox 33.

[0071] By using a reduction gearbox 33 and a frequency-modulated motor 34 to change the travel speed of the three-dimensional hydraulic power trolley, the three-dimensional hydraulic power trolley can stably decelerate when it approaches the hydraulic lifting gantry 4, preventing it from affecting the steel beams to be transported and improving the safety and stability of the transport.

[0072] In an embodiment of the present application, the support 1 is installed on both sides of the bridge position, the support 1 is installed on the road surface, the Bailey frame 2 and the guide rail are installed on the top of the support 1, the guide rail is used for the three-dimensional hydraulic power trolley to travel, the installed segment steel beam is three segments, i.e., the Z1 segment steel beam, the Z2 segment steel beam and the Z3 segment steel beam, the Z1 segment steel beam, the Z2 segment steel beam and the Z3 segment steel beam are connected in sequence, and the Z3 segment steel beam is located at the front end of the first direction, and the steel guide beam is installed at the end of the Z3 segment steel beam away from the Z2 segment steel beam, which is used to ensure the stability between the installed steel beams.

[0073] In an embodiment of the present application, the support 1 is installed on both sides of the bridge position, the support 1 is installed on the road surface, the Bailey frame 2 and the guide rail are installed on the top of the support 1, the guide rail is used for the three-dimensional hydraulic power trolley to travel, the installed segment steel beam is three segments, i.e., the Z1 segment steel beam, the Z2 segment steel beam and the Z3 segment steel beam, the Z1 segment steel beam, the Z2 segment steel beam and the Z3 segment steel beam are connected in sequence, and the Z3 segment steel beam is located at the front end of the first direction, and the steel guide beam is installed at the end of the Z3 segment steel beam away from the Z2 segment steel beam, which is used to ensure the stability between the installed steel beams.

[0074] Specifically, the three-dimensional hydraulic power trolley and the hydraulic lifting portal frame 4 repeat the above steps in a cycle until the whole-hole steel beam to be carried over the hole and reaches the specified installation position, which not only improves the speed of carrying the steel beam over the hole, but also avoids the manual lifting portal frame to support the whole-hole steel beam to be carried, realizes the long-distance carrying of the whole-hole steel beam over the hole, and improves the safety of the hole.

[0075] When the three-dimensional hydraulic power trolley carries the whole-hole steel beam to be carried and travels a distance, if the steel guide beam and the Z3 segment steel beam pass through the hole, the Z3 segment steel beam is placed on the hydraulic lifting portal frame and the three-dimensional hydraulic power trolley on the other side of the bridge position, and at this time the steel guide beam and the three-dimensional hydraulic power trolley are removed.

[0076] It can be understood that the support 1 adopts a lattice column type support and is installed by a car crane. When the steel beams are connected, the car crane is also used for installation. The hydraulic lifting portal frame 4 can be wired or wireless electric control.

[0077] In an embodiment of the present application, the hydraulic lifting portal frame 4 is also provided at the end of the first direction of the whole-hole steel beam to be carried, which is used to lift and support the whole-hole steel beam to be carried. In an embodiment of the present application, the hydraulic lifting portal frame 4 is also provided at the end of the first direction of the whole-hole steel beam to be carried, which is used to lift and support the whole-hole steel beam to be carried.

[0078] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
