Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and particularly relates to a Bailey beam transverse movement and removal device. Background Art

[0002] In recent years, with the advancement of bridge construction, the use of Bailey beam support structures has increased significantly. Before pouring concrete for a bridge, multiple sets of Bailey beams are hoisted and secured to the load-bearing beams erected on the piers by a crane. Formwork supports and casting templates are then fixed to the Bailey beams. After pouring, the concrete solidifies and hardens, and the formwork supports and casting templates are removed. However, when removing the Bailey beams, the crane hook cannot lift and remove them vertically because the concrete bridge body has already formed above them, obscuring the space above them.

[0003] During actual construction, the Bailey beam is often first moved horizontally to a lifting area with the aid of an external device before being lifted and removed using a crane. Prior art discloses transverse movement devices for Bailey beam removal. For example, CN220335726U discloses a transverse dragging device for Bailey beam removal. This device uses a translation assembly comprising a wire rope and a motorized reel to drag the Bailey beam truss in a directional translation along the load-bearing crossbeam. However, the bottom of the Bailey beam truss directly contacts the load-bearing crossbeam, resulting in significant friction. Although lubricant is applied to the load-bearing crossbeam, this is still laborious and can cause frictional wear on both the Bailey beam truss and the load-bearing crossbeam.

[0004] CN111877165B also discloses a Bailey beam translation device for use in confined spaces and its construction method. The disclosed Bailey beam translation device for use in confined spaces comprises a bidirectional translation device and a unidirectional translation device, respectively, at the contact points between the two ends of the Bailey beam assembly and the I-beam. The bottoms of the bidirectional and unidirectional translation devices utilize transverse translation wheels to contact the load-bearing crossbeam, effectively resolving the problem of Bailey beam trusses moving laterally when they directly contact the load-bearing crossbeam. However, the device still presents certain problems: As the translation device slides along the load-bearing crossbeam, it sometimes deviates, necessitating the provision of a position-limiting device on the translation device. Although the position-limiting device includes retaining edges on both sides of the undercarriage that are lower than the upper flange of the I-beam, the retaining edges provide a very limited position-limiting effect. Furthermore, when the retaining edges contact the I-beam, frictional obstruction is generated, which to some extent affects the movement of the translation device.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a Bailey beam transverse movement and removal device to solve the problems existing in the Bailey beam translation device under limited space in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A Bailey beam transverse dismantling device, comprising:

[0009] The transverse trolley includes a horizontally arranged load-bearing plate, a transverse roller horizontally arranged at the bottom of the load-bearing plate, a fixed plate vertically fixed at both ends of the load-bearing plate and extending along the length direction of the transverse roller, and a limiting roller vertically arranged at both ends of the bottom of the fixed plate; wherein the bottom of the limiting roller is lower than the bottom of the transverse roller.

[0010] Preferably, the top of the fixing plate is higher than the top of the load-bearing plate.

[0011] Preferably, a limit plate is hingedly connected to the outer side of the fixed plate near the top. When the limit plate is erected, the inner wall of the limit plate is attached to the outer wall of the fixed plate, and the two limit plates are connected by connecting screws.

[0012] Preferably, support plates are fixed at the bottom of the load-bearing plate at both ends of the transverse roller; a transverse pin shaft rotatably connected to the transverse roller is provided in the middle of the transverse roller, and both ends of the transverse pin shaft pass through the support plate and are rotatably connected to the transverse roller.

[0014] Preferably, two transverse rollers are arranged at intervals.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model provides a transverse roller at the bottom of the transverse trolley that cooperates with the load-bearing crossbeam, and also provides a limit roller to limit the movement of the transverse trolley to avoid friction obstruction. When the Bailey beam frame is transversely moved to the lifting area and then lifted and removed by a crane, the transverse movement of the entire Bailey beam frame is smooth and stable, and the parallelism and straightness requirements of the I-beam load-bearing crossbeam are low, the fault tolerance rate is high, and jamming and derailment will not occur, which can improve construction efficiency.

[0026] The following is a clear and complete description of the technical solution of this utility model. Obviously, the embodiments described are part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this utility model.

[0027] Example

[0028] See attached Figure 1-6 , a Bailey beam transverse dismantling device, comprising:

[0029] The transverse trolley 1 includes a horizontally arranged load-bearing plate 11, a transverse roller 12 horizontally arranged at the bottom of the load-bearing plate 11, a fixed plate 13 vertically fixed to both ends of the load-bearing plate 11 and extending along the length direction of the transverse roller 12, and a limit roller 14 vertically arranged at both ends of the bottom of the fixed plate 13; wherein, a support plate 15 is fixed at the bottom of the load-bearing plate 11 at the positions of both ends of the transverse roller 12; a transverse pin 16 is provided in the middle of the transverse roller 12 to be rotatably connected thereto. The ends of the transverse shift pin 16 pass through the support plate 15 and are rotatably connected thereto. Fixed arms 131 are integrally formed at the bottom of each end of the fixed plate 13, each with a clearance slot 132 corresponding to the limiting roller 14. A limiting pin 17 is provided in the middle of the limiting roller 14, rotatably connected thereto. Both ends of the limiting pin 17 are bolted to the fixed arm 131. Furthermore, two transverse shift rollers 12 are spaced apart, with the bottom of the limiting roller 14 lower than the bottom of the transverse shift roller 12. It should be noted that the limiting pin 17 has a semi-cylindrical cross-sectional connection integrally formed at each end, which secures the limiting pin 17 to the fixed arm 131.

[0030] In this embodiment, the top of the fixed plate 13 is higher than the top of the load-bearing plate 11, and a limiting plate 18 is hingedly connected to the outer side of the fixed plate 13 near the top. When the limiting plate 18 is flipped upward at a certain angle 8 and erected, the inner wall of the limiting plate 18 is attached to the outer wall of the fixed plate 13, and the two limiting plates 18 are connected by a connecting screw 19.

[0031] During use, the Bailey beam 2 is first lifted upward with the aid of an external jack, and the traversing trolley 1 is then placed between the Bailey beam 2 and the load-bearing crossbeam 3. The traversing rollers 12 are now in contact with the load-bearing crossbeam 3, the limiting rollers 14 are located on both sides of the upper flange of the load-bearing crossbeam 3, the lower chord at the bottom of the Bailey beam 2 rests on the load-bearing plate 11, and the fixing plates 13 are located on both sides of the lower chord. The limiting plates 18 on both sides are then erected and then fixedly connected using the connecting screws 19. At this point, the lower chord at the bottom of the Bailey beam 2 is located between the load-bearing plate 11 and the connecting screws 19, allowing the traversing trolley 1 in this embodiment to be stably placed at the bottom of the Bailey beam 2, allowing the entire Bailey beam 2 to be subsequently moved laterally.

[0032] One end of the rope 5 is fixed to the bottom of the Bailey beam 2, and the other end is fixed to the external traction device. The Bailey beam 2 can be pulled and moved horizontally with the help of the external traction device. In actual use, a hand hoist 4 is used as a traction device. In addition, a transverse trolley 1 is respectively set at the four bottom corners of the Bailey beam 2. During the traction process, the transverse roller 12 at the bottom of the transverse trolley 1 rolls along the load-bearing beam 3. When the transverse trolley 1 is offset, the limiting roller 14 will abut against the upper flange of the load-bearing beam 3 and thus play a good limiting role to avoid friction obstruction. After the Bailey beam 2 is transversely moved to the lifting area, a crane is used to lift and dismantle it. The transverse movement process of the entire Bailey beam 2 is smooth and stable, and the requirements for the parallelism and straightness of the I-beam load-bearing beam 3 are low, the fault tolerance rate is high, and jamming and derailment will not occur, which can improve construction efficiency.
