Description

Technical Field

[0001] The utility model relates to the technical field of Bailey beam construction, in particular to a Bailey beam bracket translation device. Background Art

[0002] Bailey beam is a truss assembled with Bailey frames. Bailey frames are mostly connected by hairpins and fixed with bolts. It has the characteristics of rapid erection and strong maneuverability. Therefore, it is mostly used to build simple bridges over rivers and cliffs. It is now mostly used in engineering construction, such as gantry cranes, construction platforms, engineering access bridges, etc.

[0003] A Bailey beam support translation device with application number 202223005953.6 includes a Bailey beam support composed of a longitudinal Bailey beam and a transverse Bailey beam fixed to the lower sides of both ends of the longitudinal Bailey beam, the length direction of the longitudinal Bailey beam is the span direction of the bridge, including support beams respectively arranged under the transverse Bailey beam, a translation panel is fixedly connected under the transverse Bailey beam, a translation guide mechanism is arranged between the translation panel and the support beam, the translation guide mechanism includes a rotating round steel, the Bailey beam support can move along the width direction of the bridge, the rotating round steel and the translation panel can reduce the friction between the Bailey beam support and the translation guide mechanism, the utility model forms an integral part of the bottom of the Bailey beam support by arranging the translation panel, so as to facilitate the movement of the Bailey beam support on the translation guide mechanism; by arranging the translation guide mechanism, the friction generated when the Bailey beam support moves is reduced, so that the Bailey beam support can be conveniently shifted, and the construction is simple and the operation is convenient.

[0004] This technical solution uses round steel and other structures to form a translation guide mechanism to reduce the travel resistance of the Bailey beam and facilitate the movement of the Bailey beam. However, there is a lack of connection between the translation guide mechanisms, and direct placement is adopted. Deviations are prone to occur after placement, causing the Bailey beam to fall off to the side after movement, or causing the channel steel to be pressed, resulting in structural damage and wear. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a Bailey beam support translation device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Bailey beam support translation device, comprising a main beam, a secondary beam is fixed to the outer surface of the main beam through a connecting beam, and a steel roller is connected between the main beam and the secondary beam, a slot is provided on one side of the secondary beam, an insert block is fixed on the other side of the secondary beam, a first limit block is fixed on one side of the main beam, and a second limit block is fixed on the other side of the main beam.

[0007] By adopting the above technical solution, the first limiting block and the second limiting block between the two translation devices are connected, and the second limiting block faces the traveling direction of the Bailey beam. First, it prevents the distance between the two translation devices from increasing and affecting the movement of the Bailey beam. Second, when the Bailey beam moves on the translation devices, the weight of the Bailey beam presses down on the second limiting block, causing the second limiting block to fit tightly with the first limiting block, thus preventing a height gap between the two translation devices. At the same time, the slots and inserts between the two translation devices are also connected to each other. The cooperation of the slots and inserts prevents the two translation devices from being misaligned, thereby avoiding the occurrence of phenomena such as the subsequent displacement of the Bailey beam deviating from the steel rollers and derailing or damaging the main beam. In addition, the setting of the secondary beams increases the supporting points for the steel rollers, improves the stability and structural strength, and prevents the phenomenon that the steel rollers bend and sag in the middle area due to excessive span and affect the movement of the Bailey beam.

[0008] Further, the first limiting block is in an "L" shape, and the second limiting block is in a "" shape.

[0009] By adopting the above technical solution, the first limiting block and the second limiting block between the two translation devices are connected. First, it prevents the distance between the two translation devices from increasing and affecting the movement of the Bailey beam. Second, when the Bailey beam moves on the translation devices, the weight of the Bailey beam presses down on the second limiting block, causing the second limiting block of one translation device to fit tightly with the first limiting block of the other translation device, thus preventing a height gap between the two translation devices.

[0010] Further, the first limiting block is adapted to the second limiting block.

[0011] By adopting the above technical solution, the structure is simple and convenient for disassembly and assembly, and it can prevent a large gap and a height gap between the two translation devices, improving the stability when the Bailey beam moves.

[0012] Further, the slot and the insert are detachably connected.

[0013] By adopting the above technical solution, the slots and inserts between the two translation devices are connected to each other, preventing the two translation devices from being misaligned, thereby avoiding the occurrence of phenomena such as the subsequent displacement of the Bailey beam deviating from the steel rollers and derailing or damaging the main beam.

[0014] Further, a plurality of secondary beams and steel rollers are provided, and the plurality of secondary beams and steel rollers are equally spaced.

[0015] By adopting the above technical solution, the setting of the secondary beams increases the supporting points for the steel rollers, improves the stability and structural strength, and prevents the phenomenon that the steel rollers bend and sag in the middle area due to excessive span and affect the movement of the Bailey beam.

[0016] Further, the heights of the connecting beam and the secondary beam are both less than the height of the main beam.

[0017] By adopting the above technical solution, since the heights of the connecting beam and the secondary beam are both less than that of the main beam and are located below the apex of the steel roller, the connecting beam and the secondary beam are prevented from being crushed during the movement of the Bailey beam.

[0018] Furthermore, a plurality of connecting beams are provided, and the plurality of connecting beams are distributed in a rectangular array.

[0019] By adopting the above technical solution, through the arrangement of a plurality of connecting beams, the connection between the plurality of secondary beams and between the secondary beam and the main beam is made stable.

[0020] Furthermore, friction bottom plates are connected to the bottoms of the main beam, the connecting beam and the secondary beam.

[0021] By adopting the above technical solution, while transporting the Bailey beam, the friction between the bottom plate and the ground is increased through the friction bottom plate, thereby preventing the displacement device from generating displacement.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] Through the arrangement of the main beam, the secondary beam, the steel roller, the slot, the plug, the first limiting block and the second limiting block, the first limiting block and the second limiting block between the two displacement devices are connected, and the second limiting block faces the traveling direction of the Bailey beam. First, it prevents the distance between the two displacement devices from becoming larger and affecting the movement of the Bailey beam. Second, when the Bailey beam moves on the displacement device, the weight of the Bailey beam presses the second limiting block, making the second limiting block fit tightly with the first limiting block, preventing a height gap between the two displacement devices. At the same time, the slots and plugs between the two displacement devices are also connected to each other. Through the cooperation of the slots and plugs, it is prevented that the two displacement devices are not aligned, thereby preventing the subsequent displacement of the Bailey beam from deviating from the steel roller and causing derailment or crushing the main beam. And the arrangement of the secondary beam increases the supporting points for the steel roller, improves the stability and structural strength, and prevents the phenomenon that the middle area of the steel roller bends and sags due to too large a span and affects the movement of the Bailey beam; the splicing operation is simple and convenient, only need to align and place, the positioning effect is good, preventing deviation between the two displacement devices, and the structural stability is good and not easy to deform.

[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0031] Embodiment 1:

[0032] A Bailey beam support translation device, as Figures 1-4 shown, includes a main beam 1. A secondary beam 3 is fixed to the outer surface of the main beam 1 through a connecting beam 2. The setting of the secondary beam 3 increases the support points for the steel roll 4; there are multiple connecting beams 2, and the multiple connecting beams 2 are distributed in a rectangular array, making the connection between the main beam 1 and the secondary beam 3 stable; the heights of the connecting beam 2 and the secondary beam 3 are both less than the height of the main beam 1 to prevent the Bailey beam from pressing and damaging the connecting beam 2 and the secondary beam 3 during movement; a steel roll 4 is connected between the main beam 1 and the secondary beam 3. There are multiple secondary beams 3 and steel rolls 4, and the multiple secondary beams 3 and steel rolls 4 are equally spaced, reducing the traveling resistance of the Bailey beam, thereby facilitating the movement of the Bailey beam.

[0033] Referring to Figures 1-4 , in the above embodiment, a slot 5 is opened on one side of the secondary beam 3, and an insertion block 6 is fixed on the other side of the secondary beam 3. The slot 5 is detachably connected to the insertion block 6 to prevent the two translation devices from not being aligned, thereby preventing the subsequent displacement of the Bailey beam from deviating from the steel roll 4 and causing derailment or pressing and damaging the main beam 1; a first limit block 7 is fixed on one side of the main beam 1, the first limit block 7 is in an "L" shape, a second limit block 8 is fixed on the other side of the main beam 1, the second limit block 8 is in a "7" shape, and the first limit block 7 is adapted to the second limit block 8. One is to prevent the distance between the two translation devices from becoming larger and affecting the movement of the Bailey beam. The other is that when the Bailey beam moves on the translation device, the weight of the Bailey beam presses the second limit block 8, so that the second limit block 8 of one translation device is closely attached to the first limit block 7 of another translation device, preventing a height gap between the two translation devices.

[0034] Embodiment 2:

[0035] On the basis of the above Embodiment 1, in order to prevent the connection points between the two translation devices from being stressed due to the sliding of the translation device on the ground; the following settings are now made.

[0036] Refer to Figures 1-3 In the above embodiments, friction bottom plates 9 are connected to the bottoms of the main beam 1, the connecting beam 2, and the secondary beam 3, and the friction between the friction bottom plates 9 and the ground is increased to prevent the displacement of the translation device.

[0037] The implementation principle of the present utility model is as follows: First, the staff aligns the first limit block 7 of one translation device with the second limit block 8 of another translation device, and the second limit block 8 faces the advancing direction of the Bailey beam. Then, the staff aligns the slot 5 of one translation device with the plug 6 of another translation device. After that, the staff can place one translation device on another translation device.

[0038] By connecting the first limit block 7 and the second limit block 8 between the two translation devices, on the one hand, it prevents the distance between the two translation devices from becoming larger and affecting the movement of the Bailey beam. On the other hand, when the Bailey beam moves on the translation device, the weight of the Bailey beam presses on the second limit block 8, making the second limit block 8 of one translation device closely fit with the first limit block 7 of another translation device, preventing a height gap between the two translation devices. At the same time, by connecting the slots 5 and plugs 6 between the two translation devices, it prevents the two translation devices from not being aligned, thereby avoiding the subsequent displacement of the Bailey beam from deviating from the steel roller 4 and causing derailment or damaging the main beam 1. In addition, the setting of the secondary beam 3 increases the support points for the steel roller 4, improves stability and structural strength, and prevents the phenomenon that the steel roller 4 bends and sags in the middle area due to excessive span and affects the movement of the Bailey beam.

[0039] When transporting the Bailey beam, the friction between the friction bottom plates 9 and the ground is increased to prevent the displacement of the translation device.

[0040] During disassembly, the staff only needs to lift the translation device upward to complete the separation between the two translation devices.

[0041] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and do not limit the utility model. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
