Abstract

This utility model discloses a high-speed railway single-track beam storage shared device that can be quickly converted, including a beam storage platform and a support structure set on the beam storage platform. The beam storage platform includes a double-track beam storage platform and a single-track beam storage platform set between the double-track beam storage platforms. It utilizes the space between the traditional double-track beam storage platforms.

Description

Technical Field

[0001] This utility model relates to the field of beam storage technology. More specifically, this utility model relates to a shared beam storage device for a single-track high-speed railway that can be quickly converted. Background Technology

[0002] The current state of precast high-speed railway box girder storage presents several challenges, despite relatively mature technology. Traditional storage devices often suffer from insufficient storage platforms when storing small quantities of double-track box girders or large quantities of single-track box girders. Furthermore, traditional storage methods typically occupy significant space with low stacking density, leading to wasted space. In addition, traditional storage platforms have room for improvement in terms of load-bearing stability and flexibility. Currently, fixed or movable structures resembling blocks or supports are generally used. Fixed supports have limited capacity to support certain types and sizes of box girders, while movable supports lack stability and are prone to shifting during transport, posing structural safety hazards. Summary of the Invention

[0003] The purpose of this invention is to provide a high-speed railway single-track beam storage device that can be quickly converted to solve the technical problem that existing beam storage devices cannot be dynamically adjusted to adapt to the type and quantity of box girders in order to meet the beam storage requirements.

[0004] To achieve these objectives and other advantages according to this utility model, a high-speed railway single-track beam storage and sharing device with rapid conversion is provided, comprising:

[0005] The beam storage platform includes single-line beam storage platforms and double-line beam storage platforms. Each set of single-line beam storage platforms or each set of double-line beam storage platforms is used to jointly support both ends of the box girder in the length direction. The top height of the single-line beam storage platform is greater than the top height of the double-line beam storage platform. The width of the single-line beam storage platform matches the width of the single-line box girder, and the width of the double-line beam storage platform matches the width of the double-line box girder. In the width direction of the box girder, the double-line beam storage platforms on both sides and the single-line beam storage platform in the middle can jointly support three sets of single-line box girders.

[0006] The supports are detachably installed on single-line beam storage platforms and double-line beam storage platforms, and are symmetrically installed on each set of single-line beam storage platforms or each set of double-line beam storage platforms. The top of the supports is covered with rubber pads, and one end of the bottom of the single-line box girder abuts against the rubber pads of the two supports.

[0007] Preferably, the single-line beam storage platform or the double-line beam storage platform includes two bearing platforms set at both ends of the corresponding box girder. The bottom of the bearing platform is cast downward and connected to the pipe pile foundation. The piers are detachably arranged on the top of the bearing platform and are spaced apart along the length of the bearing platform.

[0008] Preferably, the single-line beam storage platform is configured as a first platform, and the double-line beam storage platform is configured as a second platform. The length of the second platform is greater than the length of the first platform. Each second platform is provided with three sets of the aforementioned supports, and each first platform is provided with two sets of the aforementioned supports. Each pair of adjacent sets of the aforementioned supports jointly supports the bottom of one end of the single-line beam storage.

[0009] Preferably, the pier has a pair of limiting rods abutting on the front and rear sides of the single-line box girder along its length. The limiting rods are placed on the top surface of the corresponding first or second pier, and the outer ends of the limiting rods extend downward to form blocks, abutting against the corresponding end sides of the first or second pier along its length.

[0010] Preferably, the limiting rod is made of magnetic material, and a longitudinal rod is provided between the top of the pair of limiting rods. The longitudinal rod is attached to the side of one of the supports on one side of the single-line box girder in the width direction. Magnets are fixed at both ends of the bottom of the longitudinal rod to temporarily adhere to and fix it on the pair of limiting rods and limit the position of the abutting support.

[0011] Preferably, a side pipe is fixedly connected to the middle of the side of the support in a horizontal direction, and a gate-shaped rod is hung downward between the two side pipes on the same side of two adjacent supports. The bottom side of the middle of the gate-shaped rod abuts against the top of the side pipe, and the inner sides of both ends of the gate-shaped rod abut against the outer sides of the corresponding side pipes.

[0012] Preferably, the limiting rod includes a pair of sleeves and a movable rod disposed between the pair of sleeves, the stop is located at the outer end of the sleeve, and the movable rod is connected to the sleeve by a threaded connection or the two ends of the movable rod are slidably embedded in the pair of sleeves.

[0013] This utility model has at least the following beneficial effects: The high-speed railway single-track beam storage shared device of this utility model, which can be quickly converted, includes a beam storage platform and a support structure set on the beam storage platform. The beam storage platform includes a double-track beam storage platform and a single-track beam storage platform set between the double-track beam storage platforms, utilizing the space between traditional double-track beam storage platforms. The top of the support structure is connected to a rubber pad to provide upward support and buffer protection. The support structure is movably arranged on the top of the beam storage platform for group support at the bottom of the precast box girder. The relative positions on the girder storage platform are flexibly adjustable, allowing the overall girder storage method to be changed from the traditional two sets of box girders to the parallel storage of three single-line box girders within a limited space. At the same time, it can adapt to changes in beam length and width, solving the problem of storing girder in special beam yards with complex and numerous beam types. It saves land in the precast beam yard, reduces construction costs, and improves economic efficiency. In addition, the single-line girder storage platform is set higher than the double-line girder storage platform, which facilitates the subsequent retrieval of box girders on the single-line girder storage platform, reduces the possibility of wing plate collision during box girder hoisting, and improves the safety of box girder hoisting.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-4 As shown, the high-speed railway single-track beam storage and sharing device of this utility model with rapid conversion includes:

[0023] The beam storage platform includes a single-line beam storage platform 1 and a double-line beam storage platform 2. Each set of single-line beam storage platforms 1 or each set of double-line beam storage platforms 2 is used to jointly support the two ends of the box girder in the length direction. The top height of the single-line beam storage platform 1 is greater than the top height of the double-line beam storage platform 2. The width of the single-line beam storage platform 1 matches the width of the single-line box girder 15, and the width of the double-line beam storage platform 2 matches the width of the double-line box girder. In the width direction of the box girder, the double-line beam storage platforms 2 on both sides and the single-line beam storage platform 1 in the middle can jointly support three sets of single-line box girders 15.

[0024] The support pier 3 is detachably installed on the single-line beam storage platform 1 and the double-line beam storage platform 2, and is symmetrically installed on each set of single-line beam storage platform 1 or each set of double-line beam storage platform 2. The top of the support pier 3 is covered with rubber pads 4, and one end of the bottom of the single-line box girder 15 abuts against the rubber pads 4 of the two support piers 3.

[0025] The support piers 3 can be prefabricated using C50 reinforced concrete, making them easy to arrange and reuse. The top surface elevation of the support piers 3 placed on each set of single-line or double-line beam storage platforms 1 and 2 should be consistent. Compared to traditional beam storage devices, which require moving all support piers 3 to the appropriate positions for fixing when storing high-speed railway box girders (double-line or single-line box girders 15), and where each double-line platform 2 can only store one double-line or one single-line box girder 15, this device adds a single-line beam storage platform 1 between the traditional double-line and single-line beam storage platforms 2, utilizing the space between them. Furthermore, the support piers 3 on the double-line and single-line beam storage platforms 2 and 1 are aligned with the dimensions of the double-line or single-line box girder 1. The piers 3 are movable and flexibly adjustable to adapt to changes in beam length and width. When storing beams, at least the piers 3 on the side of the double-line beam storage platform 2 closest to the single-line beam storage platform 1 need to be moved to match the width of the single-line box girder 15. With the addition of a pair of piers 3 arranged at each end of the single-line beam storage platform 1, three single-line box girders 15 can be stored side by side in a limited space. This solves the problem of storing beams with complex and numerous beam types in special beam yards, saves land in the precast beam yard, reduces construction costs, and improves construction progress. The rubber pads 4 play a buffering role when storing precast box girders. The single-line beam storage platform 1 in the middle is arranged slightly higher than the double-line beam storage platforms 2 on both sides, which makes it easy to independently retrieve the single-line box girder 15 in the middle in a limited space. For a row of beam storage platforms, including two sets of double-line beam storage platforms 2 and one set of single-line beam storage platforms 1, after storing one layer of box girders on the rubber pad 4, double-layer beam storage is possible. Six box girders can be stored simultaneously in a limited space, saving beam storage land in the beam yard, improving economic efficiency, facilitating management and scheduling, accelerating construction progress, and providing a guarantee for subsequent laying.

[0026] In another technical solution, such as Figure 1-2 As shown, the single-line beam storage platform 1 or the double-line beam storage platform 2 respectively includes two bearing platforms set at both ends of the corresponding box girder, that is... Figure 1In the front-to-back direction, the bottom of the pier is cast downwards and connected to the pipe pile foundation 5. The support pier 3 is detachably arranged on the top of the pier and spaced apart along the length of the pier.

[0027] Pipe pile foundation 5 uses prestressed C80 high-strength concrete pipe piles, with four pipe piles arranged side by side under the central beam storage platform. The beam storage platform is cast integrally with C30 reinforced concrete on top of pipe pile foundation 5, adopting a high-density pile layout scheme, which occupies little space and consumes few resources. Pipe pile foundation 5 provides vertical bearing capacity, providing a stable and strong foundation for the foundation casting. The use of prestressed pipe piles results in fast construction speed, high quality, strong applicability, high efficiency, short construction period, mature construction technology, and low potential safety hazards.

[0028] In another technical solution, such as Figure 1-4 As shown, the single-line beam storage platform 1 has a first platform 6 as its base, and the double-line beam storage platform 2 has a second platform 7 as its base. The length of the second platform 7 is greater than the length of the first platform 6. Each second platform 7 is provided with three sets of the aforementioned supports 3, and each first platform 6 is provided with two sets of the aforementioned supports 3. Each pair of adjacent sets of the aforementioned supports 3 jointly support the bottom of one end of the single-line beam storage platform.

[0029] The single-line beam storage platform 1 or the double-line beam storage platform 2 each includes two foundations, and two supports 3 are set on each foundation. When only the double-line beam storage platform 2 is used to store double-line box girders, the supports 3 on the second foundation 7 are used for joint support. After the first foundation 6 is set up, two sets of the three sets of supports 3 on the second foundation 7 are retained to match the single-line box girder 15. One set is moved to the first foundation 6. A total of two sets of supports 3 on the two sides of the second foundation 7 are moved to the first foundation 6 to support the single-line box girder 15 to be placed on the first foundation 6. In this way, the turnover rate of supports 3 can be improved and the frequency of support 3 movement can be reduced.

[0030] In another technical solution, such as Figure 3-4 As shown, the pier 3 has a pair of limiting rods 8 abutting on the front and rear sides of the single-line box girder 15 along its length. The limiting rods 8 are placed on the top surface of the corresponding first pier 6 or second pier 7. The outer end of the limiting rod 8 extends downward to form a stop 9, which abuts against the corresponding end side of the first pier 6 or second pier 7 along its length.

[0031] Through such Figure 1As shown in the front and back directions, a pair of limiting rods 8 are set up to quickly place on the bearing platform. The two ends of the limiting rods 8 are hooked downwards to the left and right sides of the bearing platform. The support 3 is located between the pair of limiting rods 8, which realizes the limitation of the support 3 in the front and back directions. Or, when adjusting the position of the support 3, it is only necessary to move along the transverse track formed by the pair of limiting rods 8 to ensure the transverse consistency of the support 3 in adjustment and placement, and avoid the instability or instability of the support position when storing beams later.

[0032] In another technical solution, such as Figure 3-4 As shown, the limiting rod 8 is made of magnetic material. A longitudinal rod 10 is also provided between the tops of the pair of limiting rods 8. The longitudinal rod 10 is attached to the side of one of the supports 3 on one side of the single-line box girder 15 in the width direction. Magnets are fixed at both ends of the bottom of the longitudinal rod 10 to temporarily adhere to and fix it on the pair of limiting rods 8 and limit the position of the abutting support 3.

[0033] If the limiting rod 8 is made of ordinary iron-containing angle steel, by setting the longitudinal rod 10, it can be attached to the limiting rod 8. The longitudinal rod 10 can be set at the side of the support 3 that needs to be limited for quick limiting, thereby limiting the position of the support 3 in the horizontal plane, improving the stability of the support 3 when supported, and preventing slippage.

[0034] In another technical solution, such as Figure 3-4 As shown, a side pipe 11 is fixedly connected to the middle of the side of the support 3 in a horizontal direction. A gate-shaped rod 12 is hung downward between the two side pipes 11 on the same side of two adjacent supports 3. The bottom side of the middle part of the gate-shaped rod 12 abuts against the top of the side pipe 11, and the inner sides of both ends of the gate-shaped rod 12 abut against the outer sides of the corresponding side pipe 11.

[0035] A longitudinal rod 10 is installed on one side of the adjacent pier 3 facing each other and is attached to the limiting rod 8. A portal rod 12 is hooked downward between the two side tubes 11, which are both on the front and rear sides. The portal rod 12 quickly limits the horizontal movement of the two side tubes 11 outward, thereby limiting and determining the position of the pier 3 in the horizontal plane. The length of the portal rod 12 can be set according to the spacing requirements of the pier 3 to match the support spacing of the single-line box girder 15. Thus, the spacing of the pier 3 can also be quickly adjusted according to the length of the portal rod 12.

[0036] In another technical solution, such as Figure 3-4As shown, the limiting rod 8 includes a pair of sleeves 13 and a movable rod 14 disposed between the pair of sleeves 13. The stop block 9 is located at the outer end of the sleeve 13. The movable rod 14 is connected to the sleeve 13 by a threaded connection or by the two ends of the movable rod 14 being inserted into the pair of sleeves 13 for sliding connection. The spiral connection allows the limiting rod 8 to be rotated to adjust the total length. The embedded setting can also be additionally set with holes and elastic elements to be inserted into the holes to temporarily limit the length. The principle of these two telescopic connection adjustments is conventional technology and will not be elaborated here. By setting the limiting rod 8 as a structure that is adjustable in length direction, it can better and faster match the length changes of the first support 6 or the second support 7, and improve the applicability of the rod.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the drawings shown and described herein.
