Technical Field

[0001] The invention relates to the technical field of bridge machinery, in particular to a beam guide machine with a liftable multifunctional trolley. Background Art

[0002] The transporter-erector-machine can be used to transport concrete box girders for passenger dedicated lines at concrete beam yards and to erect concrete box girders at bridge locations.

[0003] The existing integrated transport and erection machine mainly includes two parts: a beam transport machine and a beam guide machine. The beam transport machine is used to lift the beam guide machine and the concrete box beam, and the beam guide machine is used to guide the beam transport machine to lift the concrete box beam. However, the main beam of the beam guide machine of the existing integrated transport and erection machine is divided into multiple sections of supporting beams, so that when the beam transport machine and the beam guide machine are feeding and dropping the box beam, they need to rely on the supporting beam hoisting system of the beam guide machine to lift and transport each section of the supporting beam in turn to achieve the movement of the beam guide machine. However, this structure makes the structure of the beam guide machine complicated, and the operation of the beam guide machine in the beam erection work is cumbersome, so that the beam guide machine and the beam transport machine cannot better cooperate to achieve the feeding and dropping of the box beam. In addition, in the existing integrated transport and erection machine, the beam transport machine moves directly on the main beam of the beam guide machine. When the bridge deck heights at both ends of the beam erection station to be erected are different, it will hinder the movement of the beam transport machine and affect the normal operation of the integrated transport and erection machine.

[0004] Therefore, in view of the above shortcomings, it is necessary to provide a beam guide machine that can assist the beam transport machine to achieve beam erection work on bridge decks of different heights. Summary of the invention

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the embodiment of the present invention, Figure 1 As shown, the beam guide machine with a liftable multifunctional trolley of an embodiment of the present invention is applied to an integrated transport and erection machine, wherein the integrated transport and erection machine includes a beam guide machine 100 and a beam transport machine 200, wherein the beam transport machine 200 is used to lift the beam guide machine 100 and a concrete box beam (hereinafter referred to as "box beam"), and the beam guide machine 100 assists the beam transport machine 200 to cooperate in realizing the through-hole beam erection in bridge erection. Specifically, the beam transport machine 200 can transport the beam guide machine 100, and cooperate with the beam guide machine 100 to keep the beam guide machine 100 at the beam erection station. The beam transport machine 200 can also travel back and forth between the beam yard and the beam erection station, transport the box beam, and cooperate with the beam guide machine 100 to complete the erection of the box beam.

[0042] like Figure 2As shown, the guide beam machine 100 with a multifunctional trolley that can be raised and lowered according to the embodiment of the present invention includes a guide beam main beam 110, a front guide beam leg 120, a middle guide beam leg 130 and a rear guide beam leg 140, wherein the front guide beam leg 120, the middle guide beam leg 130 and the rear guide beam leg 140 are respectively arranged on the guide beam main beam 110. The front guide beam leg 120 and the middle guide beam leg 130 can move on the guide beam main beam 110 along the length direction of the guide beam main beam 110. The front guide beam leg 120 is always arranged vertically and can extend or retract from the bottom surface of the guide beam main beam 110. When the front guide beam leg 120 extends from the bottom surface of the guide beam main beam 110, it can support the guide beam main beam 110; when the front guide beam leg 120 retracts from the bottom surface of the guide beam main beam 110, it can prevent the front guide beam leg 120 from contacting the ground or other obstacles and hindering the beam transport machine 200 from transporting the guide beam machine 100. The middle guide beam leg 130 can be vertically arranged and located below the guide beam main beam 110, or can be suspended by the front suspension device 170 at the front end of the guide beam main beam 110 and suspended at the front end of the guide beam main beam 110, and the bottom surface of the middle guide beam leg 130 is not lower than the bottom surface of the guide beam main beam 110. When the middle guide beam leg 130 is located below the guide beam main beam 110, it can support the guide beam main beam 110; when the middle guide beam leg 130 is suspended at the front end of the guide beam main beam 110, it can prevent the middle guide beam leg 130 from contacting the ground or other obstacles and hindering the beam transporter 200 from transporting the guide beam machine 100. The rear guide beam leg 140 is rotatably connected to the rear end of the guide beam main beam 110, so that the rear guide beam leg 140 can rotate in a vertical plane, so that the rear guide beam leg 140 can be vertically arranged below the guide beam main beam 110 or parallel to the rear end of the guide beam main beam 110. When the rear guide beam legs 140 are arranged vertically, they can support the guide beam main beam 110 ; when the rear guide beam legs 140 are arranged horizontally, they can prevent the beam transport machine 200 from being obstructed in transporting the guide beam machine 100 .

[0043] It should be noted that, in the embodiment of the present invention, the front end of the guide beam main beam 110 and the front end of the guide beam machine 100 are the same end, specifically, the end of the guide beam machine 100 that is away from the beam transport machine 200 or not connected to the beam transport machine 200 when the bridge erection work is performed; the rear end of the guide beam main beam 110 and the rear end of the guide beam machine 100 are the same end, specifically, the end of the guide beam machine 100 that is close to the beam transport machine 200 or connected to the beam transport machine 200 when the bridge erection work is performed.

[0044] In the embodiment of the present invention, the front end of the guide beam main beam 110 is provided with a front suspension structure, and a middle leg guide rail is provided on the bottom surface of the guide beam main beam 110 along the center line, and the middle leg guide rail extends to the bottom surface of the front suspension structure, and the middle guide beam leg 130 is connected to the bottom of the guide beam main beam 110 through the middle wheel system and the middle leg guide rail, so that the middle guide beam leg 130 is connected to the middle leg guide rail, so that the middle guide beam leg 130 can move along the length direction of the guide beam main beam 110 under the guide beam main beam 110 and the front suspension structure. Among them, the middle guide beam leg 130 can slide to the front end of the guide beam main beam 110, and finally can be suspended on the front suspension mechanism at the front end of the guide beam main beam 110; the middle guide beam leg 130 can also move to the rear end of the guide beam main beam 110, and finally move to a position close to the rear guide beam leg 140. During the movement of the middle guide beam leg 130, since its maximum width is the same as the width of the guide beam main beam 110 and is located directly below the guide beam main beam 110, it will not hinder the movement of the front guide beam leg 120 or the multi-functional trolley 150, nor will it be hindered by the front guide beam leg 120 or the multi-functional trolley 150.

[0045] The front suspension structure includes a guide beam lifting frame and a winch disposed on the guide beam lifting frame. When the middle guide beam leg 130 moves from the bottom surface of one of the guide beam main beam 110 or the front suspension structure to the junction of the front suspension structure and the guide beam main beam 110 through the middle wheel system, the winch can drive the middle guide beam leg 130 to do an upward or downward movement, so that the middle guide beam leg 130 moves to the bottom surface of the other one of the guide beam main beam 110 or the front suspension structure. For example, when the middle guide beam leg 130 moves along the bottom surface of the guide beam main beam 110 to the junction of the front suspension structure and the guide beam main beam 110, the winch works and drives the middle guide beam leg 130 to do an upward movement, so that the middle guide beam leg 130 can move upward to the guide beam lifting frame, and finally move to the front end of the guide beam lifting frame. When the middle guide beam leg 130 moves in the opposite direction, the principle is the same and will not be repeated here.

[0046] like Figure 3 As shown, the middle guide beam leg 130 includes a middle upper section column, a middle middle section column 133 and a middle lower section column 134 which are connected in sequence from top to bottom in the vertical direction. The middle middle section column 133 can move relative to the middle upper section column in the vertical direction. The middle lower section column 134 is located at the bottom end of the middle guide beam leg 130, and the middle lower section column 134 can be turned over to the bottom surface of the guide beam main beam 110. At the same time, the middle middle section column 133 and the middle lower section column 134 can also rotate relative to the middle upper section column to change the angle between the middle middle section column 133 and the middle lower section column 134 and the guide beam main beam 110 in the horizontal direction.

[0047] Specifically, the middle upper section column is used to connect with the guide beam main beam 110, and plays the role of connecting the middle guide beam support leg 130 with the guide beam main beam 110. The middle middle section column 133 is slidably connected with the middle upper section column, and plays the role of supporting the guide beam main beam 110, and is used to bear the heavy load of the beam transport machine 200 through the hole. A vertically arranged middle sliding hydraulic cylinder is provided between the middle middle section column 133 and the middle upper section column, so that the middle middle section column 133 can move in the vertical direction, so that the middle middle section column 133 can move relative to the middle upper section column in its length direction, so that the middle guide beam support leg 130 can be extended or shortened as a whole, meeting the requirements for different lengths of the middle guide beam support leg 130.

[0048] At the same time, the middle upper section column can also drive the middle middle section column 133 and the middle lower section column 134 to rotate, so as to adjust the guide beam machine 100 in place according to the specific situation when building a curved bridge. Specifically, the middle upper section column includes a middle section connection part 131 and a middle section rotating part 132, the middle section connection part 131 is rotatably connected to the middle section rotating part 132, the middle section connection part 131 is connected to the guide beam main beam 110, and the middle section rotating part 132 is connected to the middle middle section column 133. In an embodiment of the present invention, the middle section connection part 131 and the middle section rotating part 132 can be connected through a middle section rotating shaft 135.

[0049] The middle and lower section column 134 includes two middle and lower section units, each of which is respectively arranged along the width direction of the guide beam main beam 110 and is respectively hingedly connected to the bottom of the middle and lower section column 133. In one embodiment of the present invention, the middle and lower section units can be respectively hingedly connected to the middle section rotating part 132. The two middle and lower section units can be respectively flipped 90° along the length direction of the guide beam main beam 110 toward the bottom surface of the guide beam main beam 110, so that the middle and lower section units have two states of vertical or horizontal, that is, the middle and lower section units have two states of vertical or parallel to the guide beam main beam 110 relative to the guide beam main beam 110, so that the overall length of the middle guide beam support leg 130 can be further extended or shortened to meet the requirements of different beam erection heights.

[0050] The middle wheel system includes a middle guide wheel, a middle reverse hanging wheel and a middle support wheel, and the middle guide wheel, the middle reverse hanging wheel and the middle support wheel are respectively arranged on the top of the middle guide beam support leg 130, specifically, they can be respectively arranged on the top of the middle upper section column.

[0051] Among them, the middle anti-hanging wheel is used to connect the middle guide beam leg 130 with the middle leg guide rail, which can play an anti-overturning role. The middle anti-hanging wheel is connected to a motor to provide power for the middle anti-hanging wheel, so that the middle anti-hanging wheel can drive the middle guide beam leg 130 to move along the middle leg guide rail. The middle guide wheel is located in the middle leg guide rail parallel to the bottom surface of the middle leg guide rail, and the diameter of the middle guide wheel is the same as the width of the middle leg guide rail, so that the middle guide wheel can guide the middle guide beam leg 130 to move according to the trajectory of the middle leg guide rail. The middle support wheel is located between the middle upper section column and the bottom surface of the guide beam main beam 110 to support the guide beam main beam 110, and can play a role in supporting the guide beam main beam 110 to move longitudinally through the hole.

[0052] like Figure 4-5 As shown, the front guide beam leg 120 includes an embracing mechanism 121, a left and right sliding beam 122 and an upper and lower sliding column 123. The front guide beam leg 120 is movably connected to the guide beam main beam 110 through the embracing mechanism 121, so that the front guide beam leg 120 can move along the length direction of the guide beam main beam 110. The left and right sliding beam 122 is movably connected to the embracing mechanism 121 in the horizontal direction, and can drive the upper and lower sliding column 123 to move along the width direction of the guide beam main beam 110. The upper and lower sliding column 123 is arranged at both ends of the left and right sliding beam 122, and can slide in the vertical direction, so that the upper and lower sliding column 123 can extend or retract the bottom surface of the guide beam main beam 110. When the upper and lower sliding columns 123 extend out of the bottom surface of the guide beam main beam 110, they can support the guide beam main beam 110; when the upper and lower sliding columns 123 are retracted into the bottom surface of the guide beam main beam 110, they can prevent them from obstructing the beam transport machine 200 from transporting the guide beam machine 100 due to contact with the ground or other obstacles.

[0053] The front guide beam leg 120 also includes a front wheel system, and the embracing mechanism 121 is sleeved on the guide beam main beam 110 and is movably connected to the guide beam main beam 110 through the front wheel system. The front wheel system includes a front load-bearing wheel 126, a front running wheel 124 and a front reverse hanging wheel 125; the front running wheel 124 is arranged between the embracing mechanism 121 and the top surface of the guide beam main beam 110, and the front running wheel 124 is connected to the driving mechanism to drive the embracing mechanism 121 to move. The front reverse hanging wheel 125 movably connects the embracing mechanism 121 to the guide beam main beam 110, which plays an anti-overturning role. Flanges are provided on both sides of the top of the guide beam main beam 110, and the front load-bearing wheel 126 is arranged between the embracing mechanism 121 and the bottom surface of the flange to play a load-bearing role.

[0054] An embracing bracket is provided on the top of the embracing mechanism 121, and the left and right sliding beams 122 can be movably arranged in the embracing bracket along the width direction of the guide beam main beam 110. The left and right sliding beams 122 can be driven by the front transverse hydraulic cylinder to move horizontally along the width direction of the guide beam main beam 110, so that the upper and lower sliding columns 123 can move synchronously along the width direction of the guide beam main beam 110 to meet the beam erection requirements of the curved section of the bridge.

[0055] The upper and lower sliding columns 123 are slidably connected to the two ends of the left and right sliding beams 122, respectively, and the upper and lower sliding columns 123 can move relative to the left and right sliding beams 122 in the vertical direction. At the same time, the distance between the two upper and lower sliding columns 123 is greater than the maximum width of the middle guide beam leg 130, so that the middle guide beam leg 130 can freely pass through the front guide beam leg 120, and the middle guide beam leg 130 and the front guide beam leg 120 will not hinder each other when they move. In the embodiment of the present invention, the upper and lower sliding columns 123 can be connected to the left and right sliding beams 122 through the front vertical hydraulic cylinder, and the upper and lower sliding columns 123 can be driven to extend or retract the bottom surface of the guide beam main beam 110 in the vertical direction to meet the requirements of different heights when erecting beams.

[0056] In an embodiment of the present invention, a front support base is provided at the bottom end of the upper and lower sliding columns 123, and the maximum width of the bottom of the front support base is smaller than the width between the upper and lower sliding columns 123, thereby ensuring that the bottom of the front guide beam leg 120 can be fully supported on the pier to be erected, and preventing the front guide beam leg 120 from being unable to reliably support the guide beam main beam 110 on the pier to be erected due to the distance between the upper and lower sliding columns 123 being greater than the width of the pier to be erected.

[0057] like Figure 6-7 As shown, the rear guide beam leg 140 includes a rear fixed section 141, a rear sliding section 142 and a rear lower section column 143 from top to bottom in the vertical direction. Among them, the rear sliding section 142 can drive the rear lower section column 143 to slide relative to the rear fixed section 141 in the vertical direction, so that the rear guide beam leg 140 can be extended or shortened as a whole, meeting the requirements for different lengths of the rear guide beam leg 140. The rear lower section column 143 can be turned toward the bottom surface of the guide beam main beam 110 (specifically, turned toward the direction of the middle guide beam leg 130), that is, the rear lower section column 143 has two states relative to the guide beam main beam 110: vertical or parallel to the guide beam main beam 110, so that the overall length of the rear guide beam leg 140 can be further extended or shortened to meet the requirements of different beam heights.

[0058] Specifically, the top end of the rear fixed section 141 is connected to the guide beam main beam 110 through the guide beam fixed shaft 144, so that the rear fixed section 141 can rotate around the guide beam fixed shaft 144, so that the rear guide beam support leg 140 can be recovered to the rear end parallel to the guide beam main beam 110, which facilitates the guide beam main beam 110 to move forward or backward without being blocked by the ground or other obstacles.

[0059] The rear guide beam leg 140 further includes a rear sliding joint 142, which is slidably connected to the rear fixed joint 141, and the rear sliding joint 142 can move relative to the rear fixed joint 141 along the length direction of the rear fixed joint 141. Specifically, the rear sliding joint 142 is connected to the rear fixed joint 141 through a rear sliding hydraulic cylinder, so that the rear sliding joint 142 can move relative to the rear fixed joint 141 along its length direction.

[0060] The rear lower section column 143 is arranged at the bottom of the rear sliding section 142, and the rear lower section column 143 can be turned over to the bottom surface of the guide beam main beam 110. Specifically, the rear lower section column 143 is arranged at the bottom of the rear sliding section 142 and is rotatably connected to the rear sliding section 142. In the embodiment of the present invention, the rear lower section column 143 and the rear sliding section 142 can be hinged. Therefore, the rear lower section column 143 can be folded up, that is, the rear lower section column 143 can be turned over on the ground of the guide beam main beam 110, so as to adjust the height of the guide beam machine 100, and realize the low-position beam erection at the tunnel entrance or the high-position beam erection in the case of no tunnel.

[0061] It should be noted that when the guide beam machine with a multifunctional trolley that can be raised and lowered according to the embodiment of the present invention is in a curved bridge erection condition, the middle guide beam leg 130 can be used as a fulcrum to control the middle and lower section columns 134 and the middle and middle section columns 133 of the middle guide beam leg 130 to rotate relative to the guide beam main beam 110, thereby changing the angle between the bottom end of the middle and lower section columns 134 and the guide beam main beam 110, so that the rear guide beam leg 140 at the rear end of the guide beam main beam 110 can be located directly above the corresponding bridge pier to be erected. And by controlling the left and right sliding cross beams 122 of the front guide beam leg 120 to move along the width direction of the guide beam main beam 110, the positions of the upper and lower sliding columns 123 are changed, so that the upper and lower sliding columns 123 are located directly above the corresponding bridge pier to be erected. In this way, the guide beam machine 100 can be adjusted into position according to the specific conditions of the curved bridge erection.

[0062] In the embodiment of the present invention, the front guide beam leg 120, the middle guide beam leg 130 and the rear guide beam leg 140 can drive the guide beam main beam 110 to rise or fall, so that the guide beam main beam 110 is at a high position or a low position. In order to ensure that the guide beam main beam 110 can be reliably adjusted in height, such as Figure 8 As shown, a jack bracket 160 is provided at the rear end of the guide beam main beam 110. When the guide beam main beam 110 is switched between a high position or a low position, the jack bracket 160 can support the jack to cooperate with the guide beam main beam 110 to adjust the height.

[0063] In one embodiment of the present invention, the jack bracket 160 is detachably connected to the guide beam main beam 110. In another embodiment of the present invention, the jack bracket 160 is movably connected to the guide beam main beam 110 and can extend or retract the rear end of the guide beam main beam 110 along the length direction of the guide beam main beam 110. In another embodiment of the present invention, the jack bracket 160 is rotatably connected to the guide beam main beam 110 so that the jack bracket 160 can extend or retract the rear end of the guide beam main beam 110.

[0064] The specific method of using the jack bracket 160 to adjust the height of the guide beam main beam 110 of the guide beam machine 100 in the embodiment of the present invention is as follows:

[0065] When the height of the guide beam main beam 110 needs to be lowered, the jack bracket 160 extends out of the rear end of the guide beam main beam 110 and is supported on the jack. The middle and lower section column 134 of the middle guide beam support leg 130 is flipped upward, and the rear lower section column 143 of the rear guide beam support leg 140 is flipped upward. The jack and the front guide beam support leg 120 are lowered at the same time so that the middle guide beam support leg 130 and the rear guide beam support leg 140 are supported on the pier to be erected. At this time, the jack can be disassembled and the jack bracket 160 can be retracted to the rear end of the guide beam main beam 110, thereby completing the switching of the guide beam main beam 110 from the high position to the low position. When the height of the guide beam main beam 110 needs to be increased, the principle is the same and will not be repeated here.

[0066] In an embodiment of the present invention, the guide beam machine 100 with a liftable multifunctional trolley also includes a multifunctional trolley 150, which is movably arranged on the guide beam main beam 110. The multifunctional trolley 150 can move relative to the guide beam main beam 110 along the length direction of the guide beam main beam 110, and is used to drive the guide beam main beam 110 to move or drive the beam transport machine 200 to move.

[0067] like Fig. 9 As shown, the multifunctional trolley 150 includes a plurality of trolleys 151 and an integral frame 152. The trolleys 151 are respectively arranged along the length direction of the guide beam main beam 110 and connected to the guide beam main beam 110. The trolleys 151 are respectively connected to the top inner side of the integral frame 152. Specifically, the trolleys 151 are respectively movably connected to the guide beam main beam 110, and the trolleys 151 can move along the length direction of the guide beam main beam 110. Every two adjacent trolleys 151 are connected by a pin shaft. The trolleys 151 are respectively connected to the top inner side of the integral frame 152 by a trolley lifting cylinder, so that the integral frame 152 can rise or fall in the vertical direction.

[0068] In the embodiment of the present invention, support platforms 153 for driving the beam transporter 200 are provided on both sides of the integral frame 152. Since the front guide beam legs 120, the middle guide beam legs 130 and the rear guide beam legs 140 can drive the guide beam main beam 110 and the multifunctional trolley 150 to synchronously perform lifting and lowering movements, the guide beam main beam 110 and the multifunctional trolley 150 are in a high position or a low position. When the guide beam main beam 110 and the multifunctional trolley 150 are in a low position, in order to ensure that the overall height of the support platform 153 remains unchanged, that is, to ensure that the height of the front traveling system of the beam transporter 200 remains unchanged, a trolley support frame is provided on the support platform 153.

[0069] In the embodiment of the present invention, a relative movement mechanism is provided between the integral frame 152 and the guide beam main beam 110, which is used to drive the multifunctional trolley 150 to move relative to the guide beam main beam 110. That is, when the multifunctional trolley 150 is fixed in position, the multifunctional trolley 150 can drive the guide beam main beam 110 to move; when the guide beam main beam 110 is fixed in position, the multifunctional trolley 150 can move on the guide beam main beam 110.

[0070] In one embodiment of the present invention, the relative movement mechanism includes a guide beam chain arranged on the guide beam main beam 110 and a mid-position driver arranged on the top of a trolley 151 near the front end of the guide beam main beam 110; the mid-position driver includes a frame sprocket and a mid-position drive motor, the guide beam chain is cooperatively connected with the frame sprocket, the mid-position drive motor can be a hydraulic motor and a reducer, the hydraulic motor drives the reducer, and drives the frame sprocket through the reducer to drive the guide beam chain, so that the multi-functional trolley 150 and the guide beam main beam 110 make relative movement.

[0071] In another embodiment of the present invention, the relative movement mechanism includes a guide beam rack arranged on the guide beam main beam 110 and a mid-position driver arranged on the top of a trolley 151 near the front end of the guide beam main beam 110; the mid-position driver includes a frame gear and a mid-position drive motor, the guide beam rack is cooperatively connected with the frame gear, and the mid-position drive motor drives the frame gear to drive the guide beam rack, so that the multi-functional trolley 150 and the guide beam main beam 110 make relative movement.

[0072] Each trolley 151 is connected to the top inner side of the integral frame 152 through the corresponding trolley lifting cylinder. The integral frame 152 of the multifunctional trolley 150 of the present invention can move up and down. When the height of the guide beam and the multifunctional trolley 150 needs to be changed according to the height of different beam erection stations, the height of the integral frame 152 can be adjusted to cooperate with the beam transporter 200 to realize the beam feeding and beam dropping operations.

[0073] In the embodiment of the present invention, the number of the trolleys 151 is six, which include one first trolley 151, three second trolleys 151 and two third trolleys 151 in order from the front end to the rear end of the guide beam main beam 110. The two side surfaces of the guide beam main beam 110 are respectively provided with trolley 151 tracks for guiding the movement of the trolleys 151. Fig.10 As shown, the first trolley 151, the second trolley 151 and the third trolley 151 respectively include a trolley cross beam 151-1 and a trolley slider 151-2. The trolley slider 151-2 is respectively arranged at both ends of the trolley cross beam 151-1 and connected to the trolley 151 track through the trolley anti-grabbing wheel 151-3 to realize the movement of the trolley 151 relative to the guide beam main beam 110. The first trolley 151 is similar in structure to the second trolley 151. Since the neutral drive is arranged at the top of the first trolley 151, the only difference is that when the neutral drive is installed at the top of the first trolley 151, in order to increase the height of the neutral drive, the height of the trolley cross beam 151-1 of the first trolley 151 is higher than that of the second trolley 151. The difference between the third trolley 151 and the first trolley 151 and the second trolley 151 is that the top of the third trolley 151 is also provided with a structure for connecting with the beam transport machine 200.

[0074] A trolley suspension mechanism 154 is provided on the top of the multifunctional trolley 150. The trolley connection mechanism 250 cooperates with the trolley suspension mechanism 154 to allow the multifunctional trolley 150 to be suspended below the beam transporting main beam 210 of the beam transporting machine 200 so that the beam transporting main beam 210 can load the guide beam main beam 110. The trolley suspension mechanism 154 is connected to the multifunctional trolley 150 through a trolley hanger. The trolley hanger can be extended or shortened in the vertical direction and drive the multifunctional trolley 150 away from or close to the beam transporting main beam 210. Fig.11As shown, there are two trolley suspension mechanisms 154, and the two trolley suspension mechanisms 154 are respectively connected to the top of two trolleys 151 (i.e., two third trolleys 151) of the multifunctional trolley 150 near the rear end of the guide beam main beam 110 through a trolley hanger. The trolley hanger includes a telescopic hanger 154-1, a first adjustment section 154-2 and a second adjustment section 154-3 connected in sequence from top to bottom along the vertical direction. The second adjustment section 154-3 is movably arranged in the first adjustment section 154-2, and the first adjustment section 154-2 is movably arranged in the telescopic hanger 154-1. The telescopic hanger 154-1 is fixedly connected to the trolley suspension mechanism 154. Specifically, the first adjustment section 154-2 and the second adjustment section 154-3 can be driven by the corresponding adjustment section hydraulic cylinders, so that the second adjustment section 154-3 can be extended or retracted to the first adjustment section 154-2, and the first adjustment section 154-2 can be extended or retracted to the telescopic bracket 154-1. When the beam transport main beam 210 moves up and down in the vertical direction, the trolley bracket can be extended and retracted to keep the height of the guide beam main beam 110 of the guide beam machine 100 and the multifunctional trolley 151 unchanged when the beam transport main beam 210 of the beam transport machine 200 is lifted and lowered, so as to meet the different height requirements of high-position beam erection, tunnel exit beam erection and tunnel entrance beam erection. Specifically, when erecting beams at a high position, the first adjustment section 154-2 is completely extended out of the telescopic bracket 154-1, and the second adjustment section 154-3 does not extend out of the first adjustment section 154-2; when erecting beams at the tunnel exit, the first adjustment section 154-2 and the second adjustment section 154-3 are completely extended out; when erecting beams at the tunnel entrance, the first adjustment section 154-2 and the second adjustment section 154-3 are completely retracted.

[0075] In the embodiment of the present invention, the top of the multifunctional trolley 150 is further provided with a trolley hanging beam 151-4 and a trolley top beam 151-5, the trolley hanging beam 151-4 is connected to the bottom of the trolley bracket, and the trolley top beam 151-5 is movably arranged between the trolley bracket and the multifunctional trolley 150 along the vertical direction relative to the trolley bracket. Specifically, as Fig.12As shown, there are two trolley hanging beams 151-4 and two trolley top beams 151-5, one trolley hanging beam 151-4 and one corresponding trolley top beam 151-5 are set as a group, and the two groups of trolley hanging beams 151-4 and trolley top beams 151-5 are respectively fixed on the top of two trolleys 151 (i.e., two third trolleys 151) near the rear end of the guide beam main beam 110. The top of the trolley hanging beam 151-4 is provided with a hanging beam hanging part, and the trolley hanging beam 151-4 is hung on the hanging beam at the bottom of the trolley hanger through the hanging beam hanging part. The trolley top beam 151-5 is located between the top surface of the trolley 151 and the trolley bracket. When the trolley connecting mechanism 250 is connected to the trolley suspension mechanism 154, the multifunctional trolley 150 is suspended below the beam transport main beam 210. After the telescopic bracket 154-1 is subjected to force, the trolley top beam 151-5 presses the trolley hanging beam 151-4 tightly, so that the trolley hanging beam 151-4 and the trolley top beam 151-5 remain locked on the bottom hanging beam of the trolley bracket.

[0076] like Fig.13 As shown, the beam transport machine 200 includes a beam transport main beam 210, a front traveling system 220, a rear traveling system 230, a lifting and hoisting structure 260, and a telescopic beam transport support leg 240. The beam transport main beam 210 is a cross beam of a box structure, the front traveling system 220 and the rear traveling system 230 are respectively fixedly connected to the two ends of the beam transport main beam 210, the front traveling system 220 is fixed to the front end of the beam transport main beam 210, and the rear traveling system 230 is fixed to the rear end of the beam transport main beam 210. The telescopic beam transport support leg 240 is arranged on the bottom surface of the beam transport main beam 210, and the telescopic beam transport support leg 240 is arranged between the front traveling system and the rear traveling system and close to the front traveling system. There are two lifting and hoisting structures 260, and the two lifting and hoisting mechanisms are respectively fixed on the bottom surface of the beam transport main beam 210 and are located between the telescopic beam transport support leg 240 and the rear traveling system 230. The distance between the two lifting structures 260 is the same as the length of the box beam. The lifting mechanism is used to lift the box beam, and the front walking system 220 and the rear walking system 230 are used to drive the beam transport main beam 210 and other structures of the beam transport machine 200 to move synchronously, so that the beam transport machine 200 can transport the guide beam machine 100 and the box beam. When the beam transport machine 200 needs to be fixed, the telescopic beam transport legs 240 can be supported on the bottom surface to fix the position of the beam transport machine 200.

[0077] It should be noted that, in the embodiment of the present invention, the front end of the beam transport main beam 210 is the same end as the front end of the beam transport machine 200, specifically, the end of the beam transport machine 200 that is close to the guide beam machine 100 or connected to the guide beam machine 100 when the bridge erection work is performed; the rear end of the beam transport main beam 210 is the same end as the rear end of the beam transport machine 200, specifically, the end of the beam transport machine 200 that is away from the guide beam machine 100 or not connected to the guide beam machine 100 when the bridge erection work is performed.

[0078] Specifically, each lifting structure 260 includes two lifting units, which are symmetrically fixed on both sides of the beam transporting main beam 210. Each lifting structure 260 is used to connect with the front and rear ends of the box beam, and lift the box beam to facilitate the transportation of the box beam.

[0079] The bottom surface of the front end of the beam transport main beam 210 is provided with an inwardly concave step surface, and the front walking system 220 is fixed on the step surface. Since the front end of the beam transport main beam 210 is provided with a step surface, it is possible to prevent the front end bottom surface of the beam transport main beam 210 from colliding or rubbing with the rear end of the guide beam main beam 110 when the guide beam main beam 110 is connected to the beam transport main beam 210, thereby avoiding obstruction of the connection between the beam transport main beam 210 and the guide beam machine 100, which causes the beam transport machine 200 to be unable to transport the guide beam machine 100.

[0080] In an embodiment of the present invention, the front traveling system and the rear traveling system can synchronously drive the beam transporting main beam 210 to perform lifting motion, so that the beam transporting main beam 210 performs lifting motion in the vertical direction. Specifically, the front traveling system 220 includes a front traveling support 221, which is connected to the front end of the beam transporting main beam 210 and can drive the beam transporting main beam 210 to perform lifting motion. The front traveling system 220 also includes a front traveling wheel set 222, which is arranged at the bottom of the front traveling support 221 and can drive the front traveling support 221 to perform lifting motion. There are two front traveling wheel sets 222, and the two front traveling wheel sets 222 are arranged in parallel along the length direction of the beam transporting main beam 210, and the distance between the two front traveling wheel sets 222 is greater than the maximum width of the beam guide machine 100. The rear traveling system 230 includes a rear traveling support, which is connected to the rear end of the beam transporting main beam 210 and can drive the beam transporting main beam 210 to perform lifting motion. The rear travel system 230 also includes a rear travel wheel set, which is arranged at the bottom of the rear travel frame and can drive the rear travel frame to do lifting and lowering movements. There are two rear travel wheel sets, which are arranged in parallel along the length direction of the beam transport main beam 210, and the distance between the two rear travel wheel sets is greater than the maximum width of the beam guide machine 100.

[0081] Since the front walking system 220 and the rear walking system 230 have the same structure in the embodiment of the present invention, Figure 14-15As shown, the front travel system 220 is used as an example for explanation. The front travel system 220 includes a front travel bracket 221 and two front travel wheel groups 222. The front travel bracket 221 is used to connect the front travel wheel group 222 to the lower end of the beam transport main beam 210, so that the front travel wheel group 222 can drive the front end of the beam transport main beam 210 to move. The midpoint of the front travel bracket 221 is fixed to the front end of the beam transport main beam 210 through the front travel lifting system 223. The front travel lifting system 223 can be a front travel hydraulic cylinder. The front travel hydraulic cylinder can raise or lower the beam transport main beam 210 in the vertical direction to meet the requirements of different beam erection heights. At the same time, the front walking bracket 221 is arranged along the length direction of the beam transporting main beam 210, and a front walking wheel set 222 is arranged on both sides of the bottom end of the front walking bracket 221 along the length direction of the beam transporting main beam 210, and the distance between the two front walking wheel sets 222 is greater than the maximum width of the beam guide machine 100, so that the beam guide machine 100 can pass between the two front walking wheel sets 222, which is convenient for the beam transporting machine 200 and the beam guide machine 100 to cooperate, so that the beam guide machine 100 moves to the beam erection station or completes the erection of the box beam. The front walking wheel set 222 is connected to the bottom of the front walking bracket 221 through the front wheel hydraulic cylinder, and can drive the front walking bracket 221 to do lifting and lowering movements, and further drive the beam transporting main beam 210 to rise or fall.

[0082] The two front walking wheel groups 222 have the same structure, both of which include a vertically arranged front wheel bracket 224, and a plurality of front walking rollers 225 are evenly distributed at the bottom of each front wheel bracket 224. Each front walking roller 225 is connected to the front wheel bracket 224 through a front steering mechanism. Specifically, a front steering shaft is vertically arranged on the front steering mechanism, and the front steering shaft can rotate along its axis. The front walking roller 225 is fixed to the bottom end of the front steering shaft, so that the front steering shaft can drive the front walking roller 225 to rotate around the axis of the front steering shaft, thereby completing the adjustment of the walking direction of the front walking roller 225. The front walking roller 225 is also correspondingly provided with a front walking steering system 226, a front walking power system and a front walking brake system. The front walking steering system 226 can drive the front steering shaft to rotate to change the walking direction of the front walking roller 225, the front walking power system can drive the front walking roller 225 to roll forward or backward, and the front walking brake system can control the front walking roller 225 to stop moving.

[0083] like Fig.16As shown, the telescopic beam transporting legs 240 can be extended or shortened along the length direction thereof. Specifically, the telescopic beam transporting legs 240 include a primary beam transporting legs 241 and a secondary beam transporting legs 242, wherein the primary beam transporting legs 241 are connected to the beam transporting main beam 210, and the secondary beam transporting legs 242 are slidably connected to the primary beam transporting legs 241, so that the secondary beam transporting legs 242 can move relative to the primary beam transporting legs 241 along the length direction of the primary beam transporting legs 241, thereby realizing the use of the telescopic beam transporting legs 240 to fix the position of the beam transporting machine 200.

[0084] The telescopic beam transport leg 240 also includes a beam transport leg cross beam 243, which is used to connect the first-level beam transport leg 241 with the beam transport main beam 210. The beam transport leg cross beam 243 is horizontally arranged and connected to the beam transport main beam 210. The first-level beam transport leg 241 is fixed at both ends of the beam transport leg cross beam 243.

[0085] Among them, the midpoint of the beam transport leg cross beam 243 is fixed on the beam transport main beam 210, and the beam transport leg cross beam 243 is arranged perpendicular to the beam transport main beam 210, and the two ends of the beam transport leg cross beam 243 are respectively connected to the first beam transport leg 241, and the first beam transport leg 241 is respectively arranged perpendicular to the beam transport leg cross beam 243. The second beam transport leg 242 is inserted into the first beam transport leg 241, and the second beam transport leg 242 is connected to the hydraulic cylinder of the beam transport leg, and controls the second beam transport leg 242 to move along the length direction of the first beam transport leg 241.

[0086] The telescopic beam transporting leg 240 also includes a beam transporting leg connection system 244, which is a tripod structure and is respectively fixedly connected to the primary beam transporting leg 241, the secondary beam transporting leg 242 and the beam transporting leg cross beam 243. The beam support leg connection system plays the role of supporting and fixing the primary beam transporting leg 241, the secondary beam transporting leg 242 and the beam transporting leg cross beam 243.

[0087] The telescopic beam transporting leg 240 also includes a beam transporting ball joint base 245 , which is fixed to the bottom of the secondary beam transporting leg 242 .

[0088] In the embodiment of the present invention, since the telescopic beam transport leg 240 can be extended or shortened along its length direction, the front guide beam leg 120 and the middle guide beam leg 130 can move along the length direction of the guide beam main beam 110, and the rear guide beam leg 140 can be flipped along the length direction of the guide beam main beam 110, therefore, the telescopic beam transport leg 240, the front guide beam leg 120, the middle guide beam leg 130 and the rear guide beam leg 140 can cooperate to realize the movement of the guide beam machine 100 between the various piers to be erected. The guide beam machine 100 can be moved between the various piers to be erected only by the beam transport machine 200 and the guide beam machine 100, without the need to add auxiliary equipment to move the guide beam machine 100 to the beam erection station.

[0089] In order to enable the telescopic beam transporting legs 240 to adapt to the ramp, in the embodiment of the present invention, the top end of the telescopic beam transporting legs 240 is rotatably connected to the beam transporting main beam 210, so that the telescopic beam transporting legs 240 swing along the length direction of the beam transporting main beam 210 below the beam transporting main beam 210. In addition, a beam transporting oblique support beam 246 is provided between the telescopic beam transporting legs 240 and the beam transporting main beam 210.

[0090] In one embodiment of the present invention, the diagonal beam transporting support beam 246 is fixedly connected to the main beam transporting beam 210, and the diagonal beam transporting support beam 246 is hingedly connected to the telescopic beam transporting support leg 240. The diagonal beam transporting support beam 246 can be extended and retracted along its length direction to change the angle between the telescopic beam transporting support leg 240 and the main beam transporting beam 210. Specifically, the bottom end of the diagonal beam transporting support beam 246 is hingedly connected to the lower end of the secondary beam transporting support leg 242, and the diagonal beam transporting support beam 246 is fixedly connected to the main beam transporting beam 210 through the diagonal beam transporting hydraulic cylinder. The hydraulic cylinder can drive the diagonal beam transporting support beam 246 to perform telescopic movement, thereby changing the angle between the telescopic beam transporting support leg 240 and the main beam transporting beam 210.

[0091] In another embodiment of the present invention, one end of the beam transport oblique support beam 246 is hingedly connected to the beam transport main beam 210, and the telescopic beam transport leg 240 is provided with a plurality of connection points, and the other end of the beam transport oblique support beam 246 can be connected to different connection points to change the angle between the telescopic beam transport leg 240 and the beam transport main beam 210. Specifically, the primary beam transport leg 241 and the secondary beam transport leg 242 of the telescopic beam transport leg 240 are provided with a plurality of connection points along the length direction thereof, and the beam transport oblique support beam 246 is connected to different connection points to change the angle between the telescopic beam transport leg 240 and the beam transport main beam 210. Among them, the connection point can be a slot, and the beam transport oblique support beam 246 is inserted into the slot to connect to different slots.

[0092] like Fig.13As shown, the beam transport machine 200 further includes a trolley connection mechanism 250, which is fixed to the lower surface of the beam transport main beam 210 and is located between the front trolley system and the telescopic beam transport support leg 240, and is used to connect with the trolley of the beam guide machine 100 to transport and fix the position of the beam guide machine 100. Specifically, the trolley connection mechanism 250 includes a trolley connection part 251 and a beam transport connection part 252, the trolley connection part 251 is connected to the trolley suspension mechanism 154, and the beam transport connection part 252 connects the trolley connection part 251 and the beam transport main beam 210. The beam transport connection part 252 is fixed to the bottom of the beam transport main beam 210, and specifically, the beam transport connection part 252 can be connected to the beam transport main beam 210 through a beam transport connection hydraulic cylinder, and can perform telescopic movement in the vertical direction. The trolley connection part 251 is movably arranged at the bottom of the beam transport connection part 252. Specifically, the trolley connection part 251 can be connected to the beam transport connection part 252 through a trolley connection hydraulic cylinder and can move along the length direction of the beam transport main beam 210. Therefore, the beam transport connection part 252 can drive the trolley connection part 251 to move up and down to adjust the height of the trolley connection part 251. The trolley connection part 251 can move forward and backward along the beam transport main beam 210 to connect or disconnect with the multifunctional trolley 150.

[0093] Below, according to Figure 17-24 As shown, taking the method of installing the guide beam machine at the beam erection station as an example, the operation method of the integrated transport and erection machine of the guide beam machine with a liftable multifunctional trolley according to the embodiment of the present invention is explained.

[0094] The beam erection station 320 is the last hole to be erected on the bridge deck close to the guide beam main beam 110 equipped with the guide beam machine 100. The method of using the guide beam machine to assist the beam transport machine 200 to complete the box beam erection includes the following steps:

[0095] S1. Install the beam guide machine 100 at the beam erection station 320.

[0096] In an embodiment of the present invention, the method of installing the guide beam machine 100 at the beam erection station 320 includes:

[0097] S11, the guide beam machine 100 is in the state of beam erection completion at the penultimate hole to be erected near the bridge deck carrying the guide beam main beam 110. At this time, the front end of the guide beam machine 100 is mounted on the bridge deck away from the beam transporter 200, the front guide beam support leg 120 of the guide beam machine 100 is supported on the bridge deck, the rear guide beam support leg 140 of the guide beam machine 100 is supported on the first bridge pier 350 to be erected near the beam transporter 200, and the middle guide beam support leg 130 of the guide beam machine 100 is located between the beam erection stations 320 (between the second bridge pier 330 to be erected near the beam transporter 200 and the first bridge pier 350 to be erected).

[0098] S12, the front travel system 220 of the beam transporter 200 moves to the support platform 153 of the multifunctional trolley 150 of the beam guide machine 100. After the multifunctional trolley 150 moves to the support platform 153, the trolley connection mechanism 250 of the beam transporter 200 is connected to the trolley suspension structure, and the telescopic beam transport legs 240 of the beam transporter 200 are supported on the first bridge pier 350 to be erected near the beam transporter 200.

[0099] S13, the multifunctional trolley 150 drives the front walking system 220 to rise and keep the height of the beam transporting main beam 210 of the beam transporting machine 200 unchanged, so that the bottom surface of the supporting platform 153 is higher than the bridge deck carrying the guide beam main beam 110, which facilitates the multifunctional trolley 150 to move on the bridge deck away from the beam transporting machine 200.

[0100] S14, driving the guide beam main beam 110 to move, so that the rear guide beam support leg 140 of the guide beam main beam 110 is retracted to a horizontal position. The method of driving the guide beam main beam 110 to move is to use the multifunctional trolley 150 of the guide beam machine 100 to drive the guide beam main beam 110 to move along the length direction of the guide beam main beam 110. Fig.17 As shown, the multifunctional trolley 150 drives the guide beam main beam 110 to move forward, so that the distance between the rear end of the guide beam main beam 110 and the bridge deck 310 carrying the beam transporter 200 is greater than the length of the rear guide beam support leg 140, and then the rear guide beam support leg 140 is flipped upward so that the rear guide beam support leg 140 is horizontally arranged at the rear end of the guide beam main beam 110. At the same time, the middle guide beam support leg 130 can move forward and be supported on the second bridge pier 330 to be erected near the beam transporter 200.

[0101] S15, the multifunctional trolley 150 drives the guide beam main beam 110 to move backward, so that the front end of the guide beam main beam 110 is located in the beam erection station 320, so as to recycle the middle guide beam support leg 130 of the guide beam machine 100 to the front suspension device 170 at the front end of the guide beam machine 100, as shown in FIG. Fig.18 As shown. In this process, in order to facilitate the front end of the guide beam main beam 110 to move to the beam erection station 320, the upper and lower sliding columns 123 of the front guide beam support leg 120 of the guide beam machine 100 are retracted upward and moved to the front end of the guide beam main beam 110.
