Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering construction, in particular to an installation device for an inter-pile horizontal bracing structure. Background Art

[0002] When constructing large-scale water-crossing bridge projects, it is generally necessary to build a temporary trestle to provide a temporary passage for water-crossing projects and allow vehicles loaded with construction raw materials or semi-finished products to pass. The temporary trestle usually consists of pipe piles, an inter-pile horizontal bracing structure and various load-bearing beams. When constructing the inter-pile horizontal bracing structure above the water surface, a floating crane device is usually used to transport the inter-pile horizontal bracing structure between two pipe piles, and then the inter-pile horizontal bracing structure is welded to the pipe piles. Only after the welding is completed can the floating crane device release the hook. The floating crane device takes a long time and has a relatively low utilization rate, affecting the project progress.

[0003] Under the above background, there is an installation device for an inter-pile horizontal bracing structure in the related technology. A support beam is erected on the pipe piles to replace the floating crane device to play a supporting role, and the utilization efficiency of the floating crane device is improved. However, the adjustment mechanism provided in the installation device in the related technology can only adjust the vertical position of the inter-pile horizontal bracing structure and cannot adjust the distance between the inter-pile horizontal bracing structure and the pipe piles. The welding process between the inter-pile horizontal bracing structure and the pipe piles will thus be affected, and the welding quality will be reduced. Summary of the Utility Model

[0004] Based on the above problems, the purpose of the utility model is to provide an installation device for an inter-pile horizontal bracing structure, which can adjust the distance between the inter-pile horizontal bracing structure and the pipe piles, improve the welding quality, and at the same time enhance the stability of the welding process and improve the utilization rate of the floating crane device.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The installation device for an inter-pile horizontal bracing structure includes:

[0007] A support member, arranged on the pipe pile and used for connecting the floating crane device;

[0008] An adjustment assembly, including a suspension member, an adjustment member and a driving member. The adjustment member is connected to the inter-pile horizontal bracing structure between two adjacent pipe piles through the suspension member. The adjustment member can slide on the support member under the driving action of the driving member to adjust the distance between the inter-pile horizontal bracing structure and the pipe piles through the suspension member.

[0009] Preferably, a slide rail is arranged on the support member, and the adjustment member is slidably arranged on the slide rail.

[0010] Optionally, a slideway beam is arranged on the support member, and the slide rail is arranged on the slideway beam.

[0011] Optionally, a fixing block is arranged on the slideway beam, the fixed end of the driving member is connected to the fixing block, and the output end of the driving member is connected to the adjusting member.

[0013] Preferably, the supporting member includes a first supporting beam and a second supporting beam which are arranged at intervals, the suspension member penetrates through the gap between the first supporting beam and the second supporting beam, and the first supporting beam is connected to the second supporting beam through the first lifting lug.

[0014] Optionally, the driving member includes a pulley and a traction chain, the traction chain is arranged on the pulley, the pulley is arranged on the supporting member, and the output end of the traction chain is connected to the adjusting member.

[0015] Preferably, the inter-pile bracing structure includes a rod-shaped structure and a sleeve, the end of the rod-shaped structure is welded to the pipe pile through the sleeve, and the suspension member is connected to the rod-shaped structure.

[0016] Optionally, the supporting member is erected on two adjacent pipe piles.

[0017] Preferably, there are two groups of adjustment assemblies arranged at intervals.

[0018] The beneficial effects of the present utility model are as follows:

[0019] For the inter-pile bracing structure installation device provided by the present utility model, when installing the inter-pile bracing structure, the driving member drives the adjusting member to move on the supporting member, and then the suspension member drives the movement of the inter-pile bracing structure, adjusting the distance between the inter-pile bracing structure and the pipe pile before welding operation, improving the welding position accuracy of the inter-pile bracing structure relative to the pipe pile, thereby improving the welding quality between the inter-pile bracing structure and the pipe pile; using the floating crane device to hoist the inter-pile bracing structure installation device as a whole to the pipe pile, making the supporting member support on the top of the pipe pile, the floating crane device can be unhooked and continue to complete other construction operations, eliminating the drawback of the traditional construction that requires the floating crane device to be occupied for a long time, improving the utilization efficiency of the floating crane device, and during the subsequent welding process, using the supporting member instead of the floating crane device to bear the inter-pile bracing structure can effectively reduce the influence on the welding construction of the inter-pile bracing structure caused by the undulation of the sea waves when using the floating crane device, improving the stability of the welding process.

[0025] To make the technical problems solved by the present utility model, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present utility model will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] Such as Figures 1 to 2As shown in the figure, the utility model provides an installation device for the inter-pile horizontal connection structure. This installation device for the inter-pile horizontal connection structure can be used to install the inter-pile horizontal connection structure 4 between two adjacent pipe piles 3 during the construction of bridge projects. It can adjust the distance between the inter-pile horizontal connection structure 4 and the pipe pile 3 before welding, improve the welding position accuracy of the inter-pile horizontal connection structure 4 relative to the pipe pile 3, and thus improve the welding quality between the inter-pile horizontal connection structure 4 and the pipe pile 3.

[0029] Specifically, this installation device for the inter-pile horizontal connection structure includes a support member 1 and an adjustment assembly 2.

[0030] Among them, as Figure 1 shown, the support member 1 is arranged on the pipe pile 3 and can be used to connect the floating crane device. The support member 1 can be fixedly arranged on one pipe pile 3. The fixed connection between the support member 1 and the pipe pile 3 can adopt a detachable manner, which is convenient for disassembling and installing the inter-pile horizontal connection structure 4 between different pipe piles 3. The support member 1 can also be erected on two adjacent pipe piles 3. The support member 1 can be a beam-like structure. When using the floating crane device to hoist the installation device for the inter-pile horizontal connection structure, the support member 1 can be supported on the tops of two adjacent pipe piles 3, ensuring that the support member 1 is reasonably stressed when bearing the inter-pile horizontal connection structure 4, the support process is stable, and it can also provide enough adjustment space for the adjustment assembly 2. Of course, the support member 1 can also be erected on multiple pipe piles 3, and the support member 1 can be a frame-like structure, such as a triangular frame or a square frame.

[0031] Use the floating crane device to hoist the installation device for the inter-pile horizontal connection structure as a whole to the pipe pile 3, so that the support member 1 is supported on the top of the pipe pile 3, and then the floating crane device can unhook and continue to complete other construction operations, improving the utilization efficiency of the floating crane device. During the subsequent welding process, using the support member 1 to bear the inter-pile horizontal connection structure 4 can effectively reduce the impact on the welding construction of the inter-pile horizontal connection structure 4 caused by the undulation of sea waves when using the floating crane device, and improve the stability of the welding process.

[0032] Specifically, the adjustment assembly 2 includes a suspension member 21 connected to one end of the inter-pile horizontal connection structure 4, an adjustment member 22 connected to the other end of the suspension member 21, and a driving member 23 for driving the adjustment member 22 to move. The adjustment member 22 can slide on the support member 1 under the driving action of the driving member 23, so as to change the position of the inter-pile horizontal connection structure 4 through the connected suspension member 21, achieve the effect of adjusting the distance between the inter-pile horizontal connection structure 4 and the pipe pile 3, improve the welding position accuracy of the inter-pile horizontal connection structure 4 relative to the pipe pile 3, and improve the welding quality.

[0033] One end of the suspension member 21 passes through the support member 1 and is connected to the adjusting member 22, and the other end is connected to the inter-pile flat connection structure 4. To prevent the suspension member 21 from deforming when bearing the inter-pile flat connection structure 4, the manufacturing material of the suspension member 21 should have a relatively large stiffness, such as channel steel. During the actual operation process, the length of the suspension member 21 can be adjusted accordingly according to the water level during the construction period, so as to avoid affecting the welding operation due to the water level change. For example, in response to the rising water level caused by strong winds at sea, the construction personnel can adjust the length of the suspension member 21 according to the on-site survey results. The length of the suspension member 21 can be cut, or the suspension member 21 can be set as a telescopic member with an adjustable length to cope with the construction operations under various weather conditions. To avoid affecting the welding process during actual operation, the length of the suspension member 21 should be such that the welding position of the inter-pile flat connection structure 4 is 50 cm to 60 cm above the water surface.

[0034] If the adjusting member 22 slides directly on the support member 1, it will generate a large amount of friction. A slide rail 15 can be set on the support member 1. The surface of the slide rail 15 is a smooth surface compared with the support member 1. Then, the adjusting member 22 is directly set on the slide rail 15, which can reduce the friction generated during the sliding process of the adjusting member 22.

[0035] After setting the slide rail 15, there may be a certain deviation between the dimensions of the slide rail 15 and the support member 1. To prevent the slide rail 15 from shaking during the movement of the adjusting member 22, a slideway beam 14 can be connected to the support member 1, and the slide rail 15 is directly set on the slideway beam 14. The slideway beam 14 can use I-beam, and the slide rail 15 can use channel steel. The notch of the slide rail 15 is set facing the slideway beam 14, and the width of the notch of the slide rail 15 exactly matches the width of the slideway beam 14. Setting the slideway beam 14 can fix the position of the slide rail 15 on the support member 1. After setting the slideway beam 14, the bearing work of the inter-pile flat connection structure 4 can also be shared by the support member 1 and the slideway beam 14, avoiding damage to the structure of the support member 1 due to local overload.

[0036] A fixing block 16 can be set on the slideway beam 14. The fixing block 16 is used to fix the fixed end of the driving member 23, and the output end of the driving member 23 is connected to the adjusting member 22. After setting both ends of the driving member 23 to be one fixed and one adjustable, the adjustment process of the adjustment assembly 2 can be simplified. When adjusting the distance between the inter-pile flat connection structure 4 and the pipe pile 3, only the output end of the driving member 23 needs to be adjusted to achieve the adjustment effect.

[0037] To facilitate the connection between the floating crane device and the support member 1, a first lifting lug 13 can be set at the middle position of the support member 1, or two first lifting lugs 13 can be correspondingly set on both sides of the support member 1. This can reduce the requirements for the self-strength and connection strength of the first lifting lug 13 and improve the stability of the hoisting. Of course, multiple first lifting lugs 13 can also be set on the support member 1 to balance a large load, which is not limited here.

[0038] To allow the suspension member 21 to pass through the support member 1, the support member 1 can be set as a single beam structure with a middle slot, or two spaced-apart first support beams 11 and second support beams 12 can be selected as the support member 1, leaving a gap for the suspension member 21 to pass through. The first support beam 11 and the second support beam 12 can be connected by a first lifting lug 13. The first lifting lug 13 can serve as both a lifting action point and a connecting component between the first support beam 11 and the second support beam 12. When using the first support beam 11 and the second support beam 12 as the support member 1, there is no need to slot the single-beam structure support member 1 to provide sufficient space for the suspension member 21 to pass through. And after the construction is completed, the first support beam 11 and the second support beam 12 can also be recycled in other construction projects. Correspondingly, a first slide rail 151 and a second slide rail 152 can be respectively arranged on the first support beam 11 and the second support beam 12 to reduce the friction generated during the sliding process of the adjusting member 22. The gap between the first slide rail 151 and the second slide rail 152 can not only avoid the suspension member 21 but also limit the suspension member 21. Or a first slideway beam 141 and a second slideway beam 142 can be respectively arranged on the first support beam 11 and the second support beam 12 to share the load-bearing weight of the first support beam 11 and the second support beam 12. The gap between the first slideway beam 141 and the second slideway beam 142 can not only avoid the suspension member 21 but also limit the suspension member 21.

[0039] To reduce the actual work done during construction, a labor-saving machine can be selected as the driving member 23. The driving member 23 can include a pulley and a traction chain. The traction chain is arranged on the pulley, and the pulley is arranged on the support member 1. The output end of the traction chain is connected to the adjusting member 22. The cooperation of the pulley and the traction chain can achieve a labor-saving effect. For example, the driving member 23 can be a chain hoist. The chain hoist includes a hand-pulled chain, a pulley block, and a lifting chain. When the chain hoist is selected as the driving member 23, since the device itself is provided with hooks, located at one end of the lifting chain and one end of the pulley block respectively, as Figure 2 shown, a second lifting lug 161 and a third lifting lug 221 can be respectively arranged at the fixed block 16 and the adjusting member 22. The second lifting lug 161 and the third lifting lug 221 are respectively used to connect the fixed end and the output end of the driving member 23. When adjusting the position of the inter-pile bracing structure 4, the construction worker can stand near the fixed block 16, pull the hand-pulled chain, drive the sprocket to rotate, and realize the movement of the adjusting member 22 on the support member 1 through the transmission of the pulley block near the adjusting member 22, thereby driving the connected suspension member 21 to move, and finally realizing the effect of adjusting the distance between the inter-pile bracing structure 4 and the pipe pile 3. It should be noted that, Figure 2 The driving member 23 shown is only a schematic diagram of a chain hoist.

[0040] The inter-pile horizontal connection structure 4 may include a rod-shaped structure 41 and a sleeve 43. The end of the rod-shaped structure 41 is welded to the pipe pile 3 through the sleeve 43, and the suspension member 21 is connected to the rod-shaped structure 41. Compared with the inter-pile horizontal connection structure 4 that only uses the rod-shaped structure 41 without the sleeve 43, the addition of the sleeve 43 reduces the dimensional accuracy requirements for the inter-pile horizontal connection structure 4 and can be applicable to the welding operations of inter-pile horizontal connection structures 4 and pipe piles 3 with different sizes. To facilitate the connection between the inter-pile horizontal connection structure 4 and the suspension member 21, a fourth lifting lug 42 may be provided on the rod-shaped structure 41. A single fourth lifting lug 42 with a stronger load-bearing capacity may be provided in the middle of the rod-shaped structure 41, or a fourth lifting lug 42 may be provided at each end of the rod-shaped structure 41, making the force on the rod-shaped structure 41 more reasonable.

[0041] The rod-shaped structure 41 is welded to the pipe pile 3 through the sleeve 43. For convenient welding, the length of the sleeve 43 is between 25 cm and 35 cm, and the diameter of the sleeve 43 is 8 mm to 12 mm larger than the diameter of the rod-shaped structure 41. During installation, first, one end of the suspension member 21 is connected to the fourth lifting lug 42, and the other end passes through the support member 1 and is connected to the adjusting member 22 to complete the overall connection between the inter-pile horizontal connection structure 4 and the adjustment assembly 2. Then, the floating crane device lifts the entire inter-pile horizontal connection structure installation device through the first lifting lug 13, and the inter-pile horizontal connection structure installation device is hoisted onto the pipe pile 3, and the inter-pile horizontal connection structure 4 is located between two pipe piles 3. The horizontal position of the inter-pile horizontal connection structure 4 is adjusted through the adjustment assembly 2, so that one end of the rod-shaped structure 41 is closely attached to the welding position on the pipe pile 3 and welded. Then, a sleeve 43 is added to the other end of the rod-shaped structure 41 and welded. When the length of the inter-pile horizontal connection structure 4 is too small, sleeves 43 can be connected to both sides of the rod-shaped structure 41. During welding, first, the connection between the sleeve 43 and the pipe pile 3 needs to be welded, and then the connection position between the sleeve 43 and the rod-shaped structure 41 is welded. To ensure the smooth progress of the welding process, the sleeve 43 needs to be made of a material with sufficient strength to ensure that the sleeve 43 does not deform during the high-temperature welding process. The material of the sleeve 43 can be steel.

[0042] To improve the position adjustment efficiency of the inter-pile horizontal connection structure 4, two sets of adjustment assemblies 2 may be arranged at intervals on the support member 1, and the two sets of adjustment assemblies 2 may be symmetrically arranged, enabling construction workers to adjust the inter-pile horizontal connection structure 4 from both sides. In a single set of adjustment assemblies 2, either a single suspension member 21 may be provided, or two suspension members 21 may be arranged at intervals, reducing the requirements for the structural strength of a single suspension member 21 and ensuring the stability when lifting the inter-pile horizontal connection structure 4. The suspension member 21 may be two channel steels with their notches facing away from each other, with a gap left in the middle. The suspension member 21 and the fourth lifting lug 42 may be detachably connected, such as by bolt connection or pin connection. Corresponding pores may be opened at the bottom end of the suspension member 21 to correspond to the fourth lifting lug 42, facilitating the passing of bolts or pins.

[0043] After completing the welding of the inter-pile parallel structure 4 and the pipe pile 3, when removing the inter-pile parallel structure installation device, it is first necessary to release the connection between the fourth lifting ear 42 and the suspension member 21, disconnect the overall connection between the inter-pile parallel structure 4 and the adjustment assembly 2, and then disconnect the two ends of the driving member 23 from the fixed block 16 and the adjustment member 22 respectively, and remove the adjustment assembly 2. After the disassembly is completed, the support member 1 can be moved to other pipe piles 3 that have not been completed to continue the operation. During the installation and disassembly process of the inter-pile parallel structure 4, the use time of the floating lifting device is relatively short. After removing the support member 1, the floating lifting device can be moved to other inter-pile parallel structures 4 to continue other operations, thereby improving the utilization efficiency of the floating lifting device. In addition, using the support member 1 instead of the floating lifting device to carry the inter-pile parallel structure 4 can effectively reduce the impact of the ups and downs of the sea waves on the welding construction process when using the floating lifting device, and improve the stability of the welding process.
