Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the embodiment of the invention, as shown in fig. 1, the integrated machine for transporting and erecting the girder in the embodiment of the invention comprises a girder guiding machine 100 and a girder transporting machine 200, wherein the girder transporting machine 200 is used for lifting and erecting the girder guiding machine 100 and a concrete box girder (hereinafter referred to as a box girder), and the girder guiding machine 100 assists the girder transporting machine 200 so as to cooperatively realize the passing Kong Jialiang in bridge erection. Specifically, the beam machine 200 is capable of transporting the beam machine 100 and, in cooperation with the beam machine 100, leaves the beam machine 100 in the beam erecting station. The beam transport machine 200 is also capable of transporting box beams to and from a beam yard and a beam erecting station and completing erection of the box beams in cooperation with the beam guide machine 100.

As shown in fig. 2, the girder machine 100 includes a girder main girder 110, a front girder leg 120, a middle girder leg 130, and a rear girder leg 140, and the front girder leg 120, the middle girder leg 130, and the rear girder leg 140 are respectively provided on the girder main girder 110. Wherein the front guide beam legs 120 and the middle guide beam legs 130 are movable on the guide beam main beam 110 along the length direction of the guide beam main beam 110, respectively. And the front guide beam legs 120 are always vertically arranged to extend or retract from the bottom surface of the guide beam main beam 110. When the front guide beam legs 120 extend out of the bottom surface of the guide beam main beam 110, the guide beam main beam 110 can be supported; when the front guide beam legs 120 are retracted to the bottom surface of the guide beam main beam 110, they can be prevented from obstructing the girder transporting machine 100 by the girder transporting machine 200 due to contact with the ground or other obstacles. The middle guide beam supporting leg 130 can be vertically arranged and positioned below the guide beam main beam 110, or can be lifted by the front suspension device 170 at the front end of the guide beam main beam 110 and is lifted at the front end of the guide beam main beam 110, and the bottom surface of the middle guide beam supporting leg 130 is not lower than the bottom surface of the guide beam main beam 110. When the middle guide beam legs 130 are positioned below the guide beam main beams 110, the guide beam main beams 110 can be supported; when the center sill leg 130 is suspended from the front end of the sill main beam 110, the center sill leg 130 is prevented from contacting the ground or other obstacles to prevent the girder machine 200 from transporting the girder machine 100. The rear guide legs 140 are rotatably coupled to the rear end of the guide girder 110 such that the rear guide legs 140 can be rotated in a vertical plane so that the rear guide legs 140 can be vertically disposed under the guide girder 110 or in parallel with the rear end of the guide girder 110. When the rear guide beam legs 140 are vertically disposed, the guide beam main beam 110 can be supported; when the rear girder leg 140 is horizontally disposed, the girder transporting machine 200 can be prevented from being hindered from transporting the girder transporting machine 100.

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

In the embodiment of the invention, a front suspension structure is arranged at the front end of the girder main beam 110, a middle support leg guide rail is arranged on the bottom surface of the girder main beam 110 along the central line, the middle support leg guide rail extends to the bottom surface of the front suspension structure, and the middle girder support leg 130 is connected below the girder main beam 110 in a matched manner through a middle wheel train and the middle support leg guide rail, so that the middle girder support leg 130 is connected with the middle support leg guide rail, and the middle girder support leg 130 can move below the girder main beam 110 and the front suspension structure along the length direction of the girder main beam 110. The middle guide beam supporting leg 130 can slide to the front end of the guide beam main beam 110 and can be finally hung on a front hanging mechanism at the front end of the guide beam main beam 110; the middle guide beam leg 130 can also be moved to the rear end of the guide beam main beam 110 and eventually to a position near the rear guide beam leg 140. In the process of moving the middle guide beam leg 130, since the maximum width thereof is the same as the width of the guide beam main beam 110 and is located right under the guide beam main beam 110, the movement of the front guide beam leg 120 or the multifunctional trolley 150 is not hindered, and the movement of the front guide beam leg 120 or the multifunctional trolley 150 is not hindered.

The front suspension structure comprises a guide beam lifting frame and a winch arranged on the guide beam lifting frame, when the middle guide beam supporting leg 130 moves to the junction of the front suspension structure and the guide beam main beam 110 from the bottom surface of one of the guide beam main beam 110 or the front suspension structure through the middle wheel train, the winch can drive the middle guide beam supporting leg 130 to do ascending or descending movement so as to enable the middle guide beam supporting leg 130 to move 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 to the junction between the front suspension structure and the guide beam main beam 110 along the bottom surface of the guide beam main beam 110, the hoist works and drives the middle guide beam leg 130 to perform a lifting motion, so that the middle guide beam leg 130 can move upwards 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 described here.

As shown in fig. 3, the middle guide beam leg 130 includes a middle upper section column, a middle section column 133, and a middle lower section column 134 that are sequentially connected from top to bottom in the vertical direction. The middle section post 133 is movable in a vertical direction relative to the middle upper section post. 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. Meanwhile, the middle and lower section posts 133, 134 can also be rotated relative to the middle and upper section posts to change the angle of the middle and lower section posts 133, 134 with the girder 110 in the horizontal direction.

Specifically, the middle-upper section column is used for connecting with the girder 110, and serves to connect the middle girder leg 130 with the girder 110. The middle section column 133 is slidably connected with the middle section column and plays a role in supporting the girder 110 of the guide beam and is used for bearing the heavy load of the through hole of the girder transporting machine 200. The middle sliding hydraulic cylinder is arranged between the middle section column 133 and the middle section column, so that the middle section column 133 can move along the vertical direction, the middle section column 133 can move relatively to the middle section column in the length direction, the middle guide beam supporting leg 130 can be integrally lengthened or shortened, and the requirements of the middle guide beam supporting leg 130 on different lengths are met.

Meanwhile, the middle upper section column can also drive the middle section column 133 and the middle lower section column 134 to rotate, so that the girder erection machine 100 can be adjusted to be in place according to the specific situation when the curve is bridged. Specifically, the middle-upper section column includes a middle section connecting portion 131 and a middle section rotating portion 132, the middle section connecting portion 131 is rotatably connected with the middle section rotating portion 132, the middle section connecting portion 131 is connected with the guide girder 110, and the middle section rotating portion 132 is connected with the middle section column 133. In the embodiment of the present invention, the middle joint connection part 131 and the middle joint rotation part 132 may be connected by the middle joint rotation shaft 135.

The middle lower section column 134 includes two middle lower section units, each of which is disposed along the width direction of the girder 110 and is hinged to the bottom of the middle section column 133, respectively. In one embodiment of the present invention, the middle and lower joint units may be respectively hinge-coupled with the middle joint rotating parts 132. The two middle lower section units can respectively turn over 90 degrees along the length direction of the guide girder main beam 110 to the bottom surface of the guide girder main beam 110, so that the middle lower section units have two states, namely, the middle lower section units have two states which are vertical or parallel to the guide girder main beam 110 relative to the guide girder main beam 110, so that the whole length of the middle guide girder supporting leg 130 can be further prolonged or shortened, and the requirements of different girder heights are met.

The middle wheel train comprises a middle guide wheel, a middle reverse gear wheel and a middle supporting wheel, wherein the middle guide wheel, the middle reverse gear wheel and the middle supporting wheel are respectively arranged at the top of the middle guide beam supporting leg 130, and specifically, can be respectively arranged at the top of the middle section column.

The middle reverse change gear is used for connecting the middle guide beam supporting leg 130 with the middle supporting leg guide rail, so that the anti-overturning effect can be achieved. The middle reverse gear is connected with a motor to provide power for the middle reverse gear, so that the middle reverse gear can drive the middle guide beam supporting leg 130 to move along the middle supporting leg guide rail. The middle guide wheels are positioned in the middle leg rail in parallel with the bottom surface of the middle leg rail, and the diameters of the middle guide wheels are the same as the widths of the middle leg rail, so that the middle guide wheels can guide the middle guide beam legs 130 to move according to the track of the middle leg rail. The middle supporting wheel is positioned between the middle-upper section column and the bottom surface of the guide girder 110 to support the guide girder 110, and can play a role in supporting the guide girder 110 to longitudinally move through the hole.

As shown in fig. 4 to 5, the front guide beam leg 120 includes an encircling mechanism 121, a left-right sliding cross beam 122, and an up-down sliding column 123. The front guide beam supporting leg 120 is movably connected with the guide beam main beam 110 through an encircling mechanism 121, so that the front guide beam supporting leg 120 can move along the length direction of the guide beam main beam 110. The left and right slide cross members 122 are connected to the encircling mechanism 121 so as to be movable in the horizontal direction, and can drive the up and down slide columns 123 to move in the width direction of the girder main beams 110. The up-and-down sliding columns 123 are provided at both ends of the left-and-right sliding cross beam 122 and can slide in the vertical direction so that the up-and-down sliding columns 123 can extend or retract from the bottom surface of the girder main beam 110. When the upper and lower sliding columns 123 extend out of the bottom surface of the guide girder 110, the guide girder 110 can be supported; when the up-and-down sliding column 123 retracts the bottom surface of the girder 110, it can be prevented that it hinders the girder transporting machine 200 from transporting the girder transporting machine 100 due to contact with the ground or other obstacles.

The front guide beam supporting leg 120 further comprises a front wheel train, and the encircling mechanism 121 is sleeved on the guide beam main beam 110 and is movably connected with the guide beam main beam 110 through the front wheel train. The front wheel system comprises a front bearing wheel 126, a front travelling wheel 124 and a front reverse gear 125; the front travelling wheels 124 are arranged between the encircling mechanism 121 and the top surface of the guide girder 110, and the front travelling wheels 124 are connected with the driving mechanism and used for driving the encircling mechanism 121 to move. The front reverse gear 125 movably connects the encircling mechanism 121 with the girder 110, and plays a role in preventing overturning. Flanges are arranged on two sides of the top of the guide girder 110, and front bearing wheels 126 are arranged between the encircling mechanism 121 and the bottom surfaces of the flanges, so that a bearing effect is achieved.

The top of encircling the mechanism 121 is provided with an encircling bracket, and the left and right sliding cross beams 122 can be movably arranged in the encircling bracket in a penetrating manner along the width direction of the guide girder main beam 110, so that the left and right sliding cross beams 122 can horizontally move along the width direction of the guide girder main beam 110 through the driving of a front transverse moving hydraulic cylinder, and the upper and lower sliding columns 123 can synchronously move along the width direction of the guide girder main beam 110 so as to meet the girder erecting requirement of a bridge bending section.

The up-and-down sliding column 123 is slidably connected to both ends of the left-and-right sliding beam 122, respectively, and the up-and-down sliding column 123 is movable in the vertical direction relative to the left-and-right sliding beam 122. Meanwhile, 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 are not blocked by each other when moving. In the embodiment of the invention, the up-down sliding column 123 and the left-right sliding beam 122 can be connected through a front vertical moving hydraulic cylinder, and the up-down sliding column 123 is driven to extend or retract from the bottom surface of the girder 110 along the vertical direction, so as to meet the requirements of different heights during girder erection.

In the embodiment of the invention, the bottom ends of the upper and lower sliding columns 123 are provided with the front supporting base, and the maximum width of the bottom of the front supporting base is smaller than the width between the upper and lower sliding columns 123, so that the bottom of the front guide beam supporting leg 120 can be ensured to be completely supported on the pier to be erected, and the problem that the front guide beam supporting leg 120 cannot reliably support the guide beam main beam 110 on the pier to be erected due to the fact that the distance between the upper and lower sliding columns 123 is larger than the width of the pier to be erected is prevented.

As shown in fig. 6 to 7, the rear guide beam leg 140 includes a rear fixing section 141, a rear sliding section 142, and a rear lower section column 143 in this order from top to bottom in the vertical direction. The rear sliding section 142 can drive the rear lower section column 143 to slide relative to the rear fixing section 141 along the vertical direction, so that the rear guide beam supporting leg 140 can be integrally lengthened or shortened, and the requirements of different lengths of the rear guide beam supporting leg 140 are met. The rear lower section column 143 can turn over the bottom surface of the girder main beam 110 (specifically, turn over toward the middle girder leg 130), that is, the rear lower section column 143 has two states perpendicular or parallel to the girder main beam 110 with respect to the girder main beam 110, so that the overall length of the rear girder leg 140 can be further extended or shortened, and the requirements of different girder heights can be satisfied.

Specifically, the top end of the rear fixing section 141 is connected with the girder main beam 110 through the girder fixing shaft 144, so that the rear fixing section 141 can rotate with the girder fixing shaft 144 as an axis, and the rear girder support leg 140 can be recovered to the rear end of the girder main beam 110 which is arranged in parallel, so that the girder main beam 110 can conveniently move forwards or backwards without being blocked by the ground or other obstacles.

The rear guide beam leg 140 further includes a rear sliding section 142, the rear sliding section 142 is slidably connected to the rear fixing section 141, and the rear sliding section 142 is movable relative to the rear fixing section 141 along a length direction of the rear fixing section 141. Specifically, the rear sliding joint 142 is connected to the rear fixed joint 141 by a rear sliding hydraulic cylinder so that the rear sliding joint 142 can move in the length direction thereof with respect to the rear fixed joint 141.

The rear lower section column 143 is provided at the bottom of the rear sliding section 142, and the rear lower section column 143 can be turned over toward the bottom surface of the girder 110. Specifically, a rear lower section column 143 is provided at the bottom of the rear sliding section 142 and is rotatably connected to the rear sliding section 142. In an embodiment of the present invention, the rear lower section post 143 may be hinged with the rear sliding section 142. Therefore, the rear lower section column 143 can be folded, i.e. the rear lower section column 143 can be turned over to the ground of the girder main girder 110, so as to adjust the height of the girder guide 100, thereby realizing a low-level girder of a tunnel portal or a high-level girder without a tunnel condition.

It should be noted that, when the frame transporting and integrating machine of the embodiment of the present invention is in the curve bridging working condition, the middle guide beam supporting leg 130 can be used as a supporting point, and the relative rotation between the middle lower section post 134 and the middle section post 133 of the middle guide beam supporting leg 130 and the guide beam main beam 110 is controlled, so that the angle between the bottom end of the middle lower section post 134 and the guide beam main beam 110 is changed, and the rear guide beam supporting leg 140 at the rear end of the guide beam main beam 110 can be located right above the corresponding bridge pier to be erected. And the left and right sliding beams 122 of the front girder leg 120 are controlled to move along the width direction of the girder main beam 110 to change the positions of the up and down sliding columns 123, so that the up and down sliding columns 123 are located right above the corresponding piers to be erected. Thereby enabling the beam machine 100 to adjust the beam machine 100 to position according to the specific conditions when the curve bridges.

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 in a high-level station or a low-level station. In order to ensure that the girder 110 can be reliably height-adjusted, as shown in fig. 8, a jack stand 160 is provided at the rear end of the girder 110, and the jack stand 160 can support a jack to adjust the height in cooperation with the girder 110 when the girder 110 is switched between a high-level position or a low-level position.

In one embodiment of the invention, the jack mount 160 is removably connected to the guide girder 110. In another embodiment of the present invention, the jack mount 160 is movably coupled to the guide girder 110 and can extend or retract the rear end of the guide girder 110 in the length direction of the guide girder 110. In yet another embodiment of the present invention, the jack mount 160 is rotatably coupled to the guide girder 110 such that the jack mount 160 can extend or retract the rear end of the guide girder 110.

The specific method for realizing the height adjustment of the girder guide beam 110 of the girder guide machine 100 by using the jack stand 160 in the embodiment of the invention is as follows:

When the height of the girder 110 needs to be lowered, the jack stand 160 protrudes out of the rear end of the girder 110 and is supported on the jack. The middle lower section column 134 of the middle guide beam leg 130 is flipped up and the rear lower section column 143 of the rear guide beam leg 140 is flipped up. The jack and the front guide beam leg 120 are simultaneously lowered so that the middle guide beam leg 130 and the rear guide beam leg 140 are supported on the pier to be erected. At this time, the jack may be disassembled, and the jack stand 160 is retracted to the rear end of the guide girder 110, thereby completing the switching of the guide girder 110 from the high-order station to the low-order station.

As shown in fig. 20, the front end of the girder 110 is moved between girder erection stations 320 (i.e., between the second bridge pier 330 to be erected and the third bridge pier 340 to be erected).

And S3, the multifunctional trolley 150 moves forwards along the guide girder 110, so that the rear end of the integral frame 152 of the multifunctional trolley 150 is connected with the front end of the bridge deck 310 carrying the girder transporting machine 200.

Specifically, as shown in fig. 21, the front guide beam leg 120 and the multi-function carriage 150 are synchronously moved along the guide beam main beam 110 toward the front end of the guide beam main beam 110, so that the front guide beam leg 120 is moved to the front end of the middle guide beam leg 130, and the multi-function carriage 150 is moved to a position where the rear end of the integral frame 152 thereof abuts against the deck 310 of the girder-carrying machine 200.

S4, the integral frame 152 moves downwards, so that the top surface of the supporting platform 153 of the integral frame 152 is flush with the bridge deck.

Specifically, as shown in fig. 22, the integrated frame 152 of the multi-purpose carriage 150 is moved downward with respect to the deck 310 of the girder carrier 200 such that the top surfaces of the support platforms 153 on both sides of the integrated frame 152 are flush with the surface of the deck on which the girder carrier 200 is mounted.
