[0002] In the construction operation of high-speed railway bridges, double-track precast box girders and single-track precast box girders are selected for erection according to different topographies and environmental conditions faced by the line.

When replacing the spreader according to the erection requirements, the whole machine needs to be replaced.

[0040] In order to more clearly understand the above objects, features and advantages of the present invention, the solution of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0042] In the construction operation of high-speed railway bridges, double-track precast box girders and single-track precast box girders are selected for erection according to the different terrains and environmental conditions faced by the line.

[0043] Currently, with the increase in the construction scale and the improvement of the complexity of the line terrain environment, on the same high-speed railway line, there will be both the erection requirements for double-track precast box girders and the erection requirements for single-track precast box girders. This requires adjusting the spreader of the bridge girder erecting machine according to the erection requirements to meet the erection requirements of different box girders.

[0044] However, the existing spreaders are generally special spreaders for single-track or double-track precast box girders. When replacing the spreader according to the erection requirements, the whole machine needs to be replaced. The replacement process is relatively complex and the replacement efficiency is low, seriously affecting the construction operation efficiency.

[0045] To solve the above technical problems, the present application provides a bridge girder erecting machine, which may include a machine arm and two lifting beam traveling assemblies 100. The lifting beam traveling assemblies 100 are slidably engaged with the machine arm, and the lifting beam traveling assemblies 100 can slide along the extending direction of the machine arm. The two lifting beam traveling assemblies 100 are spaced apart in the extending direction of the machine arm. The two lifting beam traveling assemblies 100 provide two lifting points for the erection of precast box girders and can also provide counterweights for the machine arm.

[0046] Among them, please refer to Figures 1 to 5 , the lifting beam traveling assembly 100 includes: a lifting beam traveling crane 110, a hanging frame 120, a first double-track spreader 130, a second double-track spreader, a first single-track spreader, and a second single-track spreader 150.

[0047] Among them, please refer to Figure 1 and Figure 2 , the lifting beam traveling crane 110 is provided with a machine arm passage 111. The machine arm of the bridge girder erecting machine passes through the machine arm passage 111 and is slidably connected with the lifting beam traveling crane 110. Specifically, the top wall of the machine arm passage 111 is provided with upper guide wheels 112, and there may be multiple upper guide wheels 112. The side wall of the machine arm passage 111 is provided with side guide wheels, and there may be multiple side guide wheels. The side guide wheels may include opposite front guide wheels 114 and rear guide wheels 115.

[0048] The lower wall of the boom channel 111 is provided with a lower driving gear 113, which is driven to rotate by a motor. A guiding rack can be arranged on the lower surface of the boom, and the guiding rack can be engaged with the lower driving gear 113. When the boom is inserted into the boom channel 111, the lower driving gear 113 is engaged with the guiding rack of the boom, and the motor is driven to rotate the lower driving gear 113 to realize the movement of the beam crane 110 relative to the boom.

[0049] In a specific implementation process, two beam crane assemblies 100 are provided on the bridge erecting machine. The motors corresponding to the lower driving gears 113 in one beam crane assembly 100 (front beam crane assembly) are arranged opposite to the motors corresponding to the lower driving gears 113 in the other beam crane assembly 100 (rear beam crane assembly). That is, the motors corresponding to the front beam crane assembly are arranged on its rear side, and the motors corresponding to the rear beam crane assembly are arranged on its front side.

[0050] The upper guiding wheel 112 abuts against the upper surface of the boom, and the front guiding wheel 114 and the rear guiding wheel 115 respectively abut against the front surface and the rear surface of the boom, thereby realizing the sliding connection between the boom and the beam crane 110, and the beam crane 110 can slide along the extending direction of the boom.

[0051] Please continue to refer to Figure 1 and Figure 2 The hanger 120 is located on the side of the beam crane 110 facing the ground and is movably connected to the beam crane 110. Specifically, the hanger 120 is provided with a first wire winding pulley and a second wire winding pulley, and the first wire winding pulley and the second wire winding pulley are symmetric about the bisector of the hanger 120 in the length direction (the length direction of the hanger 120 is perpendicular to the extending direction of the boom); the beam crane 110 can include a third wire winding pulley 1101 and a fourth wire winding pulley 1102. The third wire winding pulley 1101 is arranged opposite to the first wire winding pulley, and the fourth wire winding pulley 1102 is arranged opposite to the second wire winding pulley.

[0052] In some embodiments of the present application, please refer to Figure 6, two steel wire ropes (the first steel wire rope 170 and the second steel wire rope) are used to connect the hanging beam crane 110 and the hanging bracket 120. Specifically, the hanging beam crane includes a first roller 1103, a first driving motor, a second roller 1105, a second driving motor, the first steel wire rope 170 and the second steel wire rope. The first roller 1103 is connected to the output shaft of the first driving motor, the second roller 1105 is connected to the output shaft of the second driving motor. The first steel wire rope 170 is sequentially wound around the first roller 1103, the first wire winding pulley and the third wire winding pulley 1101, and both ends of the first steel wire rope 170 are connected to the first roller 1103. The second steel wire rope is sequentially wound around the second roller 1105, the second wire winding pulley and the fourth wire winding pulley 1102, and both ends of the second steel wire rope are connected to the second roller 1105.

[0053] In a specific implementation process, the first wire winding pulley may include a first sub-pulley and a second sub-pulley. The third wire winding pulley 1101 includes a fifth sub-pulley and a sixth sub-pulley. The first steel wire rope 170 is sequentially wound around the first roller 1103, the first sub-pulley, the second sub-pulley, the fifth sub-pulley and the sixth sub-pulley. The second wire winding pulley includes a third sub-pulley and a fourth sub-pulley. The fourth wire winding pulley 1102 includes a seventh sub-pulley and an eighth sub-pulley. The second steel wire rope is sequentially wound around the second roller 1105, the third sub-pulley, the fourth sub-pulley, the seventh sub-pulley and the eighth sub-pulley.

[0054] In some other embodiments, please refer to Figure 7 , a steel wire rope (the third steel wire rope 180) is used to connect the hanging beam crane 110 and the hanging bracket 120. The hanging beam crane 110 includes a first roller 1103, a second roller 1105, a third driving motor 1104 and the third steel wire rope 180. The first roller 1103 is connected to the output shaft of the third driving motor 1104. The third steel wire rope 180 is sequentially wound around the first roller 1103, the first wire winding pulley, the third wire winding pulley 1101, the fourth wire winding pulley 1102, the second wire winding pulley and the second roller, and one end of the third steel wire rope 180 is connected to the first roller 1103, and the other end is connected to the second roller 1105.

[0055] In a specific implementation process, the first wire winding pulley may include a first sub-pulley and a second sub-pulley. The third wire winding pulley 1101 includes a fifth sub-pulley and a sixth sub-pulley. The third steel wire rope 180 is sequentially wound around the first roller 1103, the first sub-pulley, the second sub-pulley, the fifth sub-pulley, the sixth sub-pulley, the seventh sub-pulley, the eighth sub-pulley, the third sub-pulley, the fourth sub-pulley and the second roller 1105.

[0056] Thus, the movable connection between the hanging bracket 120 and the hanging beam crane 110 is realized, so that the hanging bracket 120 can move towards or away from the ground.

[0057] Among them, the two lifting beam traveling assemblies 100 on the bridge erecting machine can be such that one of them uses two steel wire ropes to connect the lifting beam traveling 110 and the hanger 120, and the other uses one steel wire rope to connect the lifting beam traveling 110 and the hanger 120, meeting the requirement of four-point lifting and three-point balance.

[0058] Please refer to Figures 3 to 5 , in the length direction of the hanger 120, the hanger 120 is successively provided with a first installation cavity 121 having a first opening, a second installation cavity 122 having a second opening, a third installation cavity 123 having a third opening, and a fourth installation cavity 124 having a fourth opening. The first opening, the second opening, the third opening, and the fourth opening all face the ground. The first installation cavity 121 and the fourth installation cavity 124 are symmetric about the bisector of the hanger 120 in the length direction, and the second installation cavity 122 and the third installation cavity 123 are symmetric about the bisector of the hanger 120 in the length direction.

[0059] The first single-line lifting beam is detachably connected to the second installation cavity 122 of the hanger 120, and the second single-line lifting beam 150 is detachably connected to the third installation cavity 123 of the hanger 120; the first single-line lifting beam is detachably connected to the second installation cavity 122, and the second single-line lifting beam 150 is detachably connected to the third installation cavity 123.

[0060] It can be understood that the working widths of the first single-line lifting beam and the second single-line lifting beam 150 are relatively small and are suitable for the erection of single-line precast box girders. The first single-line lifting beam and the second single-line lifting beam 150 are symmetrically arranged, which can ensure the stability of the lifting beam traveling assembly 100 during the hoisting of single-line precast box girders.

[0061] The first double-line lifting beam 130 is detachably connected to the first installation cavity 121 of the hanger 120, and the second double-line lifting beam is detachably connected to the fourth installation cavity 124 of the hanger 120; the first double-line lifting beam 130 is detachably connected to the first installation cavity 121, and the second single-line lifting beam 150 is detachably connected to the fourth installation cavity 124.

[0062] It can be understood that the working widths of the first double-line lifting beam 130 and the second double-line lifting beam are relatively large and are suitable for the erection of double-line precast box girders. The first double-line lifting beam 130 and the second double-line lifting beam are symmetrically arranged, which can ensure the stability of the lifting beam traveling assembly 100 during the hoisting of double-line precast box girders.

[0063] In this way, when the bridge erecting machine constructs the double-track precast box girder, it only needs to assemble the first double-track lifting beam 130 into the first installation cavity 121 and the second double-track lifting beam into the fourth installation cavity 124 to meet the erection requirements of the double-track precast box girder. When the bridge erecting machine constructs the single-track precast box girder, it only needs to remove the first double-track lifting beam 130 and the second double-track lifting beam, assemble the first single-track lifting beam into the second installation cavity 122, and assemble the second single-track lifting beam 150 into the third installation cavity 123 to meet the erection requirements of the single-track precast box girder.

[0064] Therefore, the beam lifting trolley assembly 100 provided by the present application can meet the construction of single-track precast box girders and double-track precast box girders, and has simple operation and high efficiency.

[0065] In some embodiments of the present application, please continue to refer to Figure 3 and Figure 4 , the beam lifting trolley assembly 100 may further include a first pin 131. The first double-track lifting beam 130 includes a first side plate and a second side plate opposite to each other in the length direction of the hanging bracket 120. The first side plate extends into the first installation cavity 121, and the second side plate extends into the first installation cavity 121. The first pin 131 penetrates through the first side plate, the second side plate, and the side wall of the first installation cavity 121. In this way, by setting the first pin 131, a detachable connection between the first double-track lifting beam 130 and the hanging bracket 120 is realized.

[0066] In some embodiments of the present application, please continue to refer to Figures 3 to 5 , the beam lifting trolley assembly 100 may further include a first reinforcing block. The first reinforcing block is disposed on the top wall of the first installation cavity 121. The first reinforcing block is located between the first side plate and the second side plate. The first pin 131 penetrates through the first side plate, the second side plate, the first reinforcing block, and the side wall of the first installation cavity 121. Therefore, by setting the first reinforcing block, a support point is added for the first pin 131, the upper limit of the bending moment that the first double-track lifting beam 130 can bear is increased, and the stability of the first double-track lifting beam 130 during use is further ensured.

[0067] In some embodiments of the present application, please continue to refer to Figures 3 to 5, the first double-line carrying pole 130 includes: a first functional plate 132 facing the ground and a first hanging rod 133. The first functional plate 132 is provided with a first hole group, and the first hole group includes two first holes 134. The two first holes 134 are symmetric about the bisector of the first double-line carrying pole 130 in the width direction of the hanger 120; the number of the first hanging rods 133 is two, and the two first hanging rods 133 are respectively inserted through the two first holes 134. The connection between the first double-line carrying pole 130 and the double-line precast box girder is realized through the first hanging rod 133. By symmetrically arranging the two first hanging rods 133, the first double-line carrying pole 130 can be prevented from deflecting when erecting the double-line precast box girder, thereby ensuring the stability of the connection between the first double-line carrying pole 130 and the double-line precast box girder.

[0068] Among them, the number of the first hole groups is multiple, and in the length direction of the hanger 120, the multiple first hole groups are arranged at intervals. In this way, by setting multiple first hole groups, the connection position between the first double-line carrying pole 130 and the double-line precast box girder can be finely adjusted, reducing the influence of position errors and improving the applicable range of the first double-line carrying pole 130.

[0069] In a specific implementation process, the first double-line carrying pole 130 is formed into a "U" - shaped structure, and both ends of the first functional plate 132 are respectively connected to the first side plate and the second side plate.

[0070] In some embodiments of the present application, please refer to Figures 3 to 5 , the beam - hanging traveling assembly 100 may further include a second pin. The first single - line carrying pole includes a third side plate and a fourth side plate opposite to each other in the length direction of the hanger 120. The third side plate extends into the second installation cavity 122, and the fourth side plate extends into the second installation cavity 122. The second pin is inserted through the third side plate, the fourth side plate, and the side wall of the second installation cavity 122. In this way, by setting the second pin, the detachable connection between the first single - line carrying pole and the hanger 120 is realized.

[0071] In some embodiments of the present application, please refer to Figures 3 to 5 , the beam - hanging traveling assembly 100 may further include a second reinforcing block 141. The second reinforcing block 141 is arranged on the top wall of the second installation cavity 122. The second reinforcing block 141 is located between the third side plate and the fourth side plate. The second pin is inserted through the third side plate, the fourth side plate, the second reinforcing block 141, and the side wall of the second installation cavity 122. Thus, by setting the second reinforcing block 141, a support point is added for the second pin, increasing the upper limit of the bending moment that the first single - line carrying pole can bear, and further ensuring the stability of the first single - line carrying pole during use.

[0072] In some embodiments of the present application, please refer to Figures 3 to 5, the first single-line carrying pole may include a second functional plate facing the ground and a second suspension rod 142. The second functional plate is provided with a second hole group, and the second hole group includes two second holes, and the two second holes are symmetric about the bisector of the first single-line carrying pole in the width direction of the hanger 120; the number of the second suspension rods 142 is two, and the two second suspension rods 142 are respectively inserted through the two second holes. The connection between the first single-line carrying pole and the single-line precast box girder is realized through the second suspension rod 142. By symmetrically arranging the two second suspension rods 142, the first single-line carrying pole can be prevented from deflecting when erecting the single-line precast box girder, thereby ensuring the stability of the connection between the first single-line carrying pole and the single-line precast box girder.

[0073] Wherein, the number of the second hole groups is multiple, and in the length direction of the hanger 120, the multiple second hole groups are arranged at intervals. In this way, by setting multiple second hole groups, the connection position between the first single-line carrying pole and the single-line precast box girder can be finely adjusted, reducing the influence of position errors and improving the applicable range of the first single-line carrying pole.

[0074] In some embodiments of the present application, please continue to refer to Figures 3 to 5 , the beam-hoisting trolley assembly 100 may further include a third pin 151. The second single-line carrying pole 150 includes a fifth side plate and a sixth side plate opposite to each other in the length direction of the hanger 120. The fifth side plate extends into the third installation cavity 123, and the sixth side plate extends into the third installation cavity 123. The third pin 151 is inserted through the fifth side plate, the sixth side plate and the side wall of the third installation cavity 123. In this way, by setting the third pin 151, the detachable connection between the second single-line carrying pole 150 and the hanger 120 is realized.

[0075] In some embodiments of the present application, please refer to Figures 3 to 5 , the beam-hoisting trolley assembly 100 may further include a third reinforcing block. The third reinforcing block is arranged on the top wall of the third installation cavity 123, the third reinforcing block is located between the fifth side plate and the sixth side plate, and the third pin 151 is inserted through the fifth side plate, the sixth side plate, the third reinforcing block and the side wall of the third installation cavity 123. Thus, by setting the third reinforcing block, a support point is added for the third pin 151, increasing the upper limit of the bending moment that the second single-line carrying pole 150 can bear, and further ensuring the stability of the second single-line carrying pole 150 during use.

[0076] In some embodiments of the present application, please refer to Figures 3 to 5, the second single-line carrying pole 150 includes: a third functional plate 152 facing the ground and a third hanging rod 153. The third functional plate 152 is provided with a third hole group, and the third hole group includes two third holes 154. The two third holes 154 are symmetric about the bisector of the second single-line carrying pole 150 in the width direction of the hanging frame 120; the number of the third hanging rods 153 is two, and the two third hanging rods 153 are respectively inserted through the two third holes 154. The connection between the second single-line carrying pole 150 and the single-line precast box girder is realized through the third hanging rod 153. By symmetrically arranging the two third hanging rods 153, the second single-line carrying pole 150 can be prevented from deflecting when erecting the single-line precast box girder, thereby ensuring the stability of the connection between the second single-line carrying pole 150 and the single-line precast box girder.

[0077] Among them, the number of the third hole groups is multiple, and in the length direction of the hanging frame 120, the multiple third hole groups are arranged at intervals. In this way, by setting multiple third hole groups, the connection position between the second single-line carrying pole 150 and the single-line precast box girder can be finely adjusted, reducing the influence of position errors and improving the applicable range of the second single-line carrying pole 150.

[0078] In some embodiments of the present application, please refer to Figures 3 to 5 , the beam hanging traveling assembly 100 may further include a fourth pin. The second double-line carrying pole includes a seventh side plate and an eighth side plate opposite to each other in the length direction of the hanging frame 120. The seventh side plate extends into the fourth installation cavity 124. The fourth pin is inserted through the seventh side plate, the eighth side plate and the side wall of the fourth installation cavity 124. In this way, by setting the fourth pin, the detachable connection between the second double-line carrying pole and the hanging frame 120 is realized.

[0079] In some embodiments of the present application, please refer to Figures 3 to 5 , the beam hanging traveling assembly 100 may further include a fourth reinforcing block 161. The fourth reinforcing block 161 is arranged on the top wall of the fourth installation cavity 124. The fourth reinforcing block 161 is located between the seventh side plate and the eighth side plate. The fourth pin is inserted through the seventh side plate, the eighth side plate, the fourth reinforcing block 161 and the side wall of the fourth installation cavity 124. Thus, by setting the fourth reinforcing block 161, a support point is added for the fourth pin, increasing the upper limit of the bending moment that the second double-line carrying pole can withstand and further ensuring the stability of the second double-line carrying pole during use.

[0080] In some embodiments of the present application, please continue to refer to Figures 3 to 5, the second double-line lifting beam can include a fourth functional plate facing the ground and a fourth suspension rod 162. The fourth functional plate is provided with a fourth hole group, and the fourth hole group includes two fourth holes. The two fourth holes are symmetric about the bisector of the second double-line lifting beam in the width direction of the hanger 120; the number of the fourth suspension rods 162 is two, and the two fourth suspension rods 162 are respectively inserted into the two fourth holes. The connection between the second double-line lifting beam and the double-line precast box girder is realized through the fourth suspension rod 162. By symmetrically arranging the two fourth suspension rods 162, the second double-line lifting beam can be prevented from tilting when erecting the double-line precast box girder, thereby ensuring the stability of the connection between the second double-line lifting beam and the double-line precast box girder.

[0081] Wherein, the number of the fourth hole groups is multiple, and in the length direction of the hanger 120, the multiple fourth hole groups are arranged at intervals. In this way, by arranging multiple fourth hole groups, the connection position between the second double-line lifting beam and the double-line precast box girder can be finely adjusted, reducing the influence of position errors and improving the applicable range of the second double-line lifting beam.

[0082] It can be understood that when it is necessary to erect a single-line precast box girder, only the first single-line lifting beam and the second single-line lifting beam 150 need to be assembled to the hanger 120. When it is necessary to erect a double-line precast girder, only the first double-line lifting beam 130 and the second double-line lifting beam need to be assembled to the hanger 120.

[0083] In the specific implementation process, the specifications of the first installation cavity 121, the second installation cavity 122, the third installation cavity 123 and the fourth installation cavity 124 are the same, the specifications of the first double-line lifting beam 130, the first single-line lifting beam, the second single-line lifting beam 150 and the second double-line lifting beam are the same, and they can be replaced with each other; the specifications of the first suspension rod 133, the second suspension rod 142, the third suspension rod 153 and the fourth suspension rod 162 are the same, and they can be replaced with each other; the specifications of the first bolt 131, the second bolt, the third bolt 151 and the fourth bolt are the same, and they can be replaced with each other.

[0084] Since the single-line precast box girder means that the lower structure of the beam is a single box shape and the beam body is single-line, which is suitable for the construction of bridges with smaller spans and has the characteristics of simple structure and convenient construction. The double-line precast box girder means that the lower structure of the beam is two juxtaposed box shapes and the beam body is double-line, which is suitable for the construction of bridges with larger spans and has the characteristics of strong bearing capacity and good stability. In the specific implementation process, it can also be that the specifications of the first suspension rod 133 and the fourth suspension rod 162 corresponding to the first double-line lifting beam 130 and the second double-line lifting beam are the same, the specifications of the second suspension rod and the third suspension rod 153 corresponding to the first single-line lifting beam and the second single-line lifting beam 150 are the same, and the radial dimensions of the first suspension rod 133 and the fourth suspension rod 162 are larger than the radial dimensions of the second suspension rod 142 and the third suspension rod 153 to meet the erection of the double-line precast box girder with a larger span and greater weight.

[0085] In a specific beam lifting operation, taking the erection of a double-track prefabricated box beam as an example, two beam lifting crane assemblies 100 are moved along the machine arm to the lifting position, and then the first drive motor and the second drive motor rotate, and the wire rope lowers the hanger 120. When the hanger 120 is lowered to the preset position, the hanger 120 is fixed to the double-track preset box beam by the first hanger rod 133 and the fourth hanger rod, and then the hanger 120 is raised, and the double-track prefabricated box beam is lifted to the assembly position, and the hanger 120 is lowered. After the hanger 120 is lowered to the preset position, the first hanger rod 133 and the fourth hanger rod are adjusted to separate the hanger 120 from the double-track prefabricated box beam, the hanger 120 is raised, and the beam lifting crane assembly 100 returns to the initial position, and the working process of the beam lifting crane assembly 100 is completed.
