Description

Technical Field

[0001] The present disclosure relates to the technical field of bridge construction, and in particular to a displacement device for a side cast-in-situ beam. Background Art

[0002] In the construction of viaducts across existing railway lines, beam erection machines are usually used to lay precast beams on bridge piers. Although this method is widely used, it still has obvious limitations, especially when high-speed railways are running at a high density. The working cycle of beam erection machines for laying precast beams is relatively long, and it usually takes several hours to complete the installation of a beam section. Due to the high-density operation of high-speed railways, there is almost no time window allowing beam erection machines to work for a long time. In addition, in order to ensure the safety of high-speed railways during operation, beam erection operations can usually only be carried out for a short period of time after the high-speed railways are stopped at night. This not only limits the construction time, but also leads to low construction efficiency, while also increasing the safety risks and costs of nighttime construction. Utility Model Content

[0003] The purpose of the present invention is to provide a side cast-in-situ beam displacement device, which can quickly and efficiently complete the movement of the beam body within a limited construction time without affecting the operation of the high-speed rail during the day, so as to at least partially solve the problems in the related technology.

[0004] In order to achieve the above-mentioned purpose, the present disclosure provides a displacement device for a side cast-in-place beam, comprising:

[0005] span beam;

[0006] A base is slidably connected to the upper surface of the cross beam and is provided with a mounting position for placing the cast-in-place beam;

[0007] The driving mechanism is arranged on the cross beam and has a traction machine for driving the base to move along the length direction of the cross beam. The cross beam is provided with a traction seat for fixing the traction machine.

[0008] Optionally, the base comprises a first base and a second base arranged opposite to each other along the length direction of the cross beam;

[0009] The upper surface of the first base and the upper surface of the second base are both set as the installation position, and the first base and the second base are both provided with a limiting baffle for limiting the cast-in-place beam.

[0010] Optionally, the driving mechanism further includes a pushing jack for pushing the first base or the second base, and the cross beam is provided with a pushing seat for fixing the pushing jack.

[0011] Optionally, the traction line of the traction machine is connected to one of the first base or the second base, and the output rod of the push jack abuts against the other of the first base or the second base;

[0012] The traction machine and the jacking jack are arranged opposite to each other along the length direction of the cross beam, and the first base and the second base are both placed between the traction machine and the jacking jack.

[0013] Optionally, there are multiple groups of the bases, and the multiple groups of the bases are arranged at equal intervals along the length direction of the cast-in-place beam, and each group of the bases is provided with the cross beam adapted thereto.

[0014] Optionally, a slip-aiding layer is laid on the upper surface of the cross beam.

[0015] Optionally, a sliding block corresponding to the sliding-aiding layer is provided on the bottom surface of the first base and the bottom surface of the second base.

[0016] Optionally, a correction component is also included;

[0017] The deviation-correcting components are provided on both side walls of the first base and the second base which are arranged opposite to each other along the first direction, and are used to maintain the movement tracks of the first base and the second base when they are displaced.

[0018] Optionally, the deviation-correcting assembly includes an extension frame, one end of which is fixedly connected to the first base and / or the second base, and the other end of which extends along the second direction to below the upper surface of the cross beam.

[0019] Optionally, the deviation-correcting assembly further comprises a pulley, and a mounting plate for mounting the pulley is provided at one end of the extension frame away from the first base or the second base, and the pulley is rotatably connected to the mounting plate via a pin.

[0020] Through the above technical solution, a construction platform for casting cast-in-place beams is built on one side of the railway line, and a bracket for supporting the cross-beam is built at the same time. At this time, the construction platform and the bracket should be in the same construction plane to facilitate construction operations. On this basis, after the base is slidably connected to the cross-beam, the casting operation of the cast-in-place beam is started. In order to optimize the construction process, the installation position of the base can be used as a partial template for casting the cast-in-place beam. After the pouring is completed and the concrete is solidified, the template is removed to achieve the purpose of placing part of the cast-in-place beam directly in the installation position. Afterwards, the base is towed by a traction machine to drive the cast-in-place beam to move, so that the cast-in-place beam can be quickly and efficiently moved to the top of the bridge pier, which saves a lot of time for the subsequent beam dropping operation and significantly improves the overall construction efficiency.

DETAILED DESCRIPTION

[0030] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the related art, the beam body is laid on the bridge piers by crossing the existing railway line, and the prefabricated beams are laid on the bridge piers by using a beam erecting machine. This method mainly relies on the efficient operation of the beam erecting machine. However, this method also has limitations, especially on the railway line used for high-speed rail, the limitations will be more obvious, that is, the working cycle of the beam erecting machine for laying prefabricated beams is relatively long, and it usually takes several hours to complete the installation of a beam section. Due to the high-density operation of high-speed rail, for the sake of high-speed rail driving safety, there is almost no time period for the beam erecting machine to operate during the day. Therefore, the beam erecting operation can only be carried out in a short period of time after the high-speed rail is stopped at night, which not only limits the construction time, but also leads to low overall construction efficiency. In addition, if a beam erecting machine is used for laying operations, in order to maximize the construction efficiency within a limited time, accurate and correct operation and a large amount of manpower and material support are required, which requires extremely high technical level and coordination ability of the construction team, which will further increase the construction difficulty and potential risks. Therefore, it is not preferred to use a beam erecting machine to cross the existing railway line to lay the beam body on the bridge piers;

[0033] If the beam body is not laid using a beam erector, in the related technology, a template for pouring cast-in-place beams can also be directly built on the piers, and the piers can be used as the supporting points of the templates. After the templates are built, the steel bars produced according to the installation design requirements are tied and fixed in the templates. After the tying and fixing are completed, the concrete pouring operation can be carried out. However, this construction method has safety hazards. When pouring concrete, some concrete may splash out of the template and fall onto the railway line, posing a safety hazard to the operation of high-speed railways. At the same time, the personnel cannot ensure the firmness of the template. If the template breaks during the concrete pouring process or when the concrete has not solidified in the template, the loss caused is difficult to estimate. Therefore, the method of directly pouring cast-in-place beams on the piers is not the preferred method.

[0034] Therefore, in the face of the problems existing in the above-mentioned construction process, there is an urgent need for a new construction technology that can quickly and efficiently move the beam body within a limited construction period, saving precious time for subsequent beam dropping operations.

[0035] In the specific implementation manner provided in the present disclosure, a side cast-in-place beam displacement device is provided, referring to Figures 1 to 5 As shown, the lateral cast-in-place beam displacement device includes: a cross-beam 1, a base 2 and a driving mechanism, wherein the base 2 is slidably connected to the upper surface of the cross-beam 1 and the base 2 is provided with a mounting position 203 for placing the cast-in-place beam 9, the driving mechanism is arranged on the cross-beam 1 and has a traction machine 3 for driving the base 2 to displace along the length direction of the cross-beam 1, and the cross-beam 1 is provided with a traction seat 301 for fixing the traction machine 3.

[0036] Through the above technical solution, a construction platform for casting the cast-in-place beam 9 is built on one side of the railway line to ensure that the construction platform is stable and can carry construction equipment and casting materials. At the same time, a bracket for supporting the cross beam 1 is built next to the construction platform. The cross beam 1 should span the railway line and the bridge piers to ensure that the cast-in-place beam 9 can be moved to the top of the bridge pier through the cross beam 1. It is also necessary to ensure that the bracket and the construction platform remain in the same construction plane for subsequent operations. After that, the base 2 is slidably connected to the cross beam 1 to ensure that the base 2 can move smoothly during the subsequent traction process. The installation position 203 of the base 2 is used as a template for part of the cast-in-place beam 9, that is, after the casting is completed, the part of the cast-in-place beam 9 with the template removed is placed in the installation position 203, thereby achieving the effect of optimizing the construction process. After the cast-in-place beam 9 is manufactured, the base 2 is towed by the traction machine 3 to drive the cast-in-place beam 9 to move, so that the cast-in-place beam 9 can be quickly and efficiently moved to the top of the bridge pier, saving a lot of time for the subsequent beam dropping operation and significantly improving the overall construction efficiency.

[0037] In some embodiments, the pouring operation of the cast-in-place beam 9 is carried out during the daytime. The pouring operation is not limited to the short time window when the high-speed rail is shut down at night, and the daytime can be used to prepare for the traction and movement of the cast-in-place beam 9. After the high-speed rail is shut down, the traction of the cast-in-place beam 9 can be started, thereby increasing the overall construction efficiency and gaining more time for the subsequent beam dropping operation. At the same time, in the overall construction process, except for the necessary movement of the cast-in-place beam 9 and the beam dropping operation which are carried out at night, the rest of the construction operations can be carried out during the day. The entire construction process is reasonably allocated, and the advantages of the daytime construction environment with sufficient light and clear vision are utilized, which can reduce the safety hazards of night construction and improve the overall construction safety. In turn, the additional lighting and safety measures required for night construction are reduced, the manpower and material costs are reduced, and the work efficiency of the construction personnel is improved.

[0038] In some embodiments not shown in the figure, in order to improve the connection stability between the base 2 and the cast-in-place beam 9, a steel plate with threaded holes can be embedded in advance during the casting process of the cast-in-place beam 9, and threaded holes corresponding to the threaded holes of the steel plate are provided on the mounting position 203 of the base 2. The base 2 and the steel plate are connected by screws, that is, after the template is built, steel bars should be tied and fixed in the template. At this time, the steel plate and the steel bars are fixed, and the steel plate and the base 2 are connected by screws. After that, concrete is poured into the template. After the concrete solidifies, the template is removed. At this time, part of the cast-in-place beam 9 is not only placed in the installation position 203 of the base 2, but also connected and fixed to the base 2 by a threaded rod, so that the connection between the base 2 and the cast-in-place beam 9 is more firmly established, and the stability of the cast-in-place beam 9 during movement is improved. When the cast-in-place beam 9 and the base 2 are moved to the top of the bridge pier, the cast-in-place beam 9 and the base 2 are lifted up together with the help of a jack, and the threaded rod is cut with the help of a spray gun, so as to achieve the purpose of efficiently separating the base 2 and the cast-in-place beam 9, saving limited construction time. After separating the base 2, the cross beam 1 is removed, and then the subsequent beam dropping operation is carried out.

[0039] In some embodiments not shown in the figures, the base 2 includes a base frame, an upper surface of the base frame is provided with a mounting position 203, and limit plates for limiting the cast-in-place beam 9 are provided on both sides of the upper surface of the base frame located at the mounting position 203. In order to facilitate the base 2 to be towed and moved by the traction machine 3, a slide rail can be provided on the cross beam 1, and a slider 7 adapted to the slide rail is provided on the lower surface of the base frame. At the same time, in order to prevent the base 2 from deviating during movement and causing the slider 7 to detach from the slide rail, a limit guide column can be provided on the lower surface of the base frame, and a slide groove for accommodating the limit guide column is opened on the upper surface of the cross beam 1, and the slide groove should be opened along the length direction of the cross beam 1, so that when the base 2 moves, the limit guide column is always located in the slide groove. At the same time, in order to further prevent the base 2 from deviating during movement, limit guide columns can be provided on both sides of the slider 7, and a slide groove corresponding to the limit guide column is opened on the upper surface of the cross beam 1.

[0040] In some embodiments, in order to enable the base 2 to load and support the cast-in-place beam 9 more stably, the number of the base 2 is multiple groups, wherein at least two groups are provided. When there are two groups of bases 2, the two groups of bases 2 are respectively arranged at the two ends of the cast-in-place beam 9. At the same time, each base 2 has a corresponding cross beam 1 and a traction machine 3. When the cast-in-place beam 9 needs to be moved, the traction machine 3 connected to each base 2 should be started synchronously to ensure that the traction force of the traction machine 3 is evenly distributed. In order to achieve the synchronous start-up of multiple traction machines 3, the multiple traction machines 3 can be controlled by a PLC controller. At the same time, with the help of the PLC controller, the construction personnel can also understand the various parameters of the traction machine 3 in real time, monitor the operating status of each traction machine 3, and make targeted adjustments when necessary to ensure a smooth and synchronous traction process.

[0041] In some embodiments, if the number of bases 2 is more than two groups, for example four groups, it is necessary to ensure that the four groups of bases 2 are arranged at equal intervals along the length direction of the cast-in-place beam 9. This can ensure that the beam body of the cast-in-place beam 9 is evenly stressed during the traction movement, reduce the deformation of the beam body, and ensure its structural integrity. At the same time, the equally spaced bases 2 can evenly distribute the weight of the cast-in-place beam 9 to avoid excessive pressure at a single location, thereby reducing stress concentration on the cast-in-place beam 9 and the base 2 and reducing the risk of damage.

[0042] In some embodiments, reference Figure 2 and Figure 3 As shown, due to considerations such as construction requirements, design standards, bridge location and bearing capacity, the size of the beam body may vary. In order to enable the base 2 to better load and support the cast-in-place beam 9 and improve the adaptability of the base 2, the base 2 may be designed as a split structure, that is, the base 2 includes a first base 201 and a second base 202 that are relatively arranged along the length direction of the cross beam 1, and the upper surface of the first base 201 and the upper surface of the second base 202 are both set as the installation position 203. When the cross beam 1 is built, the first base 201 and the second base 202 can be installed on the cross beam 1 in turn, and the distance between the first base 201 and the second base 202 can be adjusted according to the size of the cast-in-place beam 9 to be cast. After the adjustment is completed, the first base 201 and the second base 202 can be connected and fixed, for example, a metal rod is welded or threaded between the first base 201 and the second base 202 to ensure that the distance between the first base 201 and the second base 202 remains unchanged, and then the template for casting the cast-in-place beam 9 is The installation position 203 of the first base 201 and the installation position 203 of the second base 202 are both used as part of the template. After the template is built, the steel bars are tied to the inside of the template, and concrete is poured into the template to fill the internal space of the template. After the concrete solidifies, the template is removed. At this time, part of the cast-in-place beam 9 is directly placed in the installation position 203 of the base 2. At the same time, in order to improve the connection strength between the first base 201 and the second base 202 and the cast-in-place beam 9, a threaded member can be embedded in the template before the casting process of the cast-in-place beam 9. The steel plate with holes is provided with threaded holes corresponding to the threaded holes of the steel plate on the mounting positions 203 of the first base 201 and the mounting positions 203 of the second base 202. The base 2 and the steel plate are connected by screws. After the screw connection is completed, the pouring operation is started. The first base 201 and the second base 202 are fixedly connected to the cast-in-place beam 9 by the threaded rods, which effectively improves the stability of the cast-in-place beam 9 during movement, avoids the separation of the first base 201 and the second base 202 from the cast-in-place beam 9 during movement, and improves construction safety.

[0043] In some embodiments, reference Figure 1As shown, in order to improve the safety and stability of the first base 201 and the second base 202 when transporting the cast-in-place beam 9, a limit baffle 4 for limiting the cast-in-place beam 9 can be provided on the first base 201 and the second base 202. The limit baffle 4 on the first base 201 and the limit baffle 4 on the second base 202 are arranged relatively to each other along the length direction across the beam 1, that is, when the first base 201 and the second base 202 drive the cast-in-place beam 9 to move, the limit baffle 4 on the first base 201 and the limit baffle 4 on the second base 202 can withstand the external force from the moving direction, thereby ensuring the stability and safety of the cast-in-place beam 9 during the displacement process.

[0044] In some embodiments, reference Figure 1 As shown, since the weight of each section of the cast-in-place beam 9 that needs to be displaced is relatively large, in order to reduce the use intensity of the traction machine 3, the driving mechanism also includes a jacking jack 5 for jacking the first base 201 or the second base 202. The direction of the output rod of the jacking jack 5 should be consistent with the traction direction of the traction machine 3 to ensure that the thrust and traction force act on the cast-in-place beam 9 together. The jacking jack 5 is a high-strength hydraulic jack with sufficient thrust and stroke to effectively provide an initial driving force for the cast-in-place beam 9. A jacking seat 501 for fixing the jacking jack 5 is designed and installed on the cross beam 1 to ensure that the output rod of the jacking jack 5 is When the first base 201 or the second base 202 is thrusted, it can remain stable without any displacement in position or angle. At the same time, through control devices such as PLC, the traction machine 3 and the push jack 5 are started and operated synchronously, so that the cast-in-place beam 9 can obtain additional initial power during the movement process, thereby improving the movement efficiency. The push jack 5 provides initial thrust, which reduces the burden of the traction machine 3 during the startup and operation process and extends the service life of the traction machine 3. In addition, the use of the push jack 5 enables the side cast-in-place beam displacement device to cope with the heavier cast-in-place beam 9, meet the needs of heavy-load construction, and improve construction efficiency.

[0045] In some embodiments, the tractor 3 and the jacking jack 5 are arranged opposite to each other along the length direction of the cross beam 1, and the first base 201 and the second base 202 are both placed between the tractor 3 and the jacking jack 5. Therefore, the traction line of the tractor 3 is connected to one of the first base 201 or the second base 202, and the output rod of the jacking jack 5 abuts against the other of the first base 201 or the second base 202. Figure 1For example, the traction line of the traction machine 3 is connected to the first base 201, and the output rod of the jacking jack 5 is against the second base 202. When the cast-in-place beam 9 needs to be displaced, the traction line of the traction machine 3 pulls the first base 201, and the output rod of the jacking jack 5 pushes the second base 202. Through the coordinated cooperation of the traction machine 3 and the jacking jack 5, the moving efficiency of the cast-in-place beam 9 is improved, the construction efficiency is improved, and the load on the traction machine 3 and the jacking jack 5 is reduced.

[0046] In some embodiments, reference Figures 1 to 4 As shown, in order to reduce the load on the traction machine 3 and the push jack 5 during operation and extend their service life, a slip layer 6 can be laid on the upper surface of the cross beam 1, and a slider 7 corresponding to the slip layer 6 is provided on the bottom surface of the first base 201 and the bottom surface of the second base 202, wherein the slip layer 6 is a polytetrafluoroethylene layer or a high-density polyethylene layer, and the slider 7 is a polytetrafluoroethylene block or a high-density polyethylene block. The use of the slip layer 6 and the slider 7 significantly reduces the friction between the cross beam 1 and the first base 201 and the second base 202, reduces the load on the traction machine 3 and the push jack 5, extends their service life, and at the same time, the friction resistance is small, which can improve the stability and efficiency of the movement of the cast-in-place beam 9.

[0047] In some embodiments, reference Figures 2 to 5 As shown, when the cast-in-place beam 9 is moved, for safety reasons, it should be ensured that the cast-in-place beam 9 does not deviate from the remote trajectory when moving. Based on this, the first base 201 and the second base 202 are provided with the correcting assembly 8 on both side walls that are arranged opposite to each other along the first direction, so as to maintain the movement trajectory of the first base 201 and the second base 202 during displacement. The correcting assembly 8 includes an extension frame 801, wherein one end of the extension frame 801 can be fixed to the first base 201 and the second base 202 by welding or threaded connection. On the base 202, the other end extends along the second direction to below the upper surface of the cross beam 1, that is, the first base 201 and the second base 202 are provided with extension frames 801 on the side walls that are relatively arranged along the first direction, and at the same time, one end of the extension frame 801 extends along the second direction to below the upper surface of the cross beam 1. When the base 2 drives the cast-in-place beam 9 to move on the cross beam 1, the base 2 can be prevented from shifting during the movement under the limiting action of the extension frame 801, ensuring that the base 2 and the cast-in-place beam 9 maintain a straight line movement along the length direction of the cross beam 1.

[0048] The first direction can refer to Figure 4 The X direction in the second direction can refer to Figure 4 In the Y direction.

[0049] In some embodiments, in order to improve the safety of moving the cast-in-place beam 9, the first base 201 and the second base 202 can be fixed to the cast-in-place beam 9, and then the first base 201, the second base 202 and the cast-in-place beam 9 can be regarded as a whole. Therefore, when installing the extension frame 801, it can be installed only on the first base 201 or only on the second base 202. This can simplify the structure and reduce costs, while still ensuring the stability and safety of the cast-in-place beam 9 during the movement.

[0050] In some embodiments, reference Figures 2 to 5 As shown, a pulley 802 can also be installed at one end of the extension frame 801 close to the cross beam 1, wherein the pulley 802 is rotatably connected to the mounting plate 803 through a pin 804, and the mounting plate 803 is welded to the extension frame 801. The pulley 802 can convert the sliding friction between the extension frame 801 and the cross beam 1 into rolling friction, significantly reducing the friction coefficient, thereby reducing the resistance during the movement process and reducing the load of the traction machine 3 and the push jack 5.

[0051] Description of the operation process: a construction platform for casting the cast-in-place beam 9 is built on one side of the railway line, and a bracket for supporting the cross beam 1 is built next to the construction platform. The cross beam 1 should cross the railway line and the bridge piers to ensure that the cast-in-place beam 9 can be moved to the top of the bridge pier through the cross beam 1. At the same time, it is also necessary to ensure that the bracket and the construction platform remain in the same construction plane for subsequent operations. After that, the base 2 is slidably connected to the cross beam 1 to ensure that the base 2 can smoothly drive the cast-in-place beam 9 to move during the subsequent traction process. In order to optimize the construction process and improve construction efficiency, the installation position 203 of the first base 201 and the installation position 203 of the second base 202 can be used as part of the cast-in-place beam 9. The template for casting the cast-in-place beam 9 is constructed on the mounting position 203 of the first base 201 and the mounting position 203 of the second base 202. The mounting position 203 of the first base 201 and the mounting position 203 of the second base 202 provide support for the template. Then, the pre-designed steel bars are tied and fixed in the template. At the same time, in order to strengthen the connection strength between the first base 201 and the second base 202 and the cast-in-place beam 9, a steel plate can be added in the template when tying the steel bars. The steel plate is provided with threaded holes. The first base 201 and the second base 202 are also provided with threaded holes. Before pouring concrete, the first base 201 and the second base 202 are connected to the steel plate by threaded rods. The plate is connected. After the connection is completed, check whether the template construction and the bundled steel bars are qualified. After the inspection is completed, start pouring concrete. The steel plate is fixed in the template by the concrete, so that the cast-in-place beam 9 is connected to the first base 201 and the second base 202 through the threaded rod. During pouring, the construction personnel can use a vibrating rod to vibrate the concrete to make it dense, so as to prevent quality problems such as honeycombs and pockmarks. After pouring, the cast-in-place beam 9 is cured. After the curing is completed, the template can be removed. Then, the first base 201 and the second base 202 are driven by the joint action of the traction machine 3 and the push jack 5 to drive the cast-in-place beam 9 to move. When moving, the extension frame 801 and the pulley 802 can ensure that the cast-in-place beam 9 The telecontrol track will not deviate during movement. The movement can be stopped when the cast-in-place beam 9 moves to the top of the bridge pier. The cast-in-place beam 9 can be lifted with the help of a jack, so that the cast-in-place beam 9 together with the first base 201 and the second base 202 are lifted up, and the first base 201 and the second base 202 are separated from the cross beam 1. At this time, the personnel can use a spray gun to cut the threaded rod connected between the first base 201 and the second base 202 and the cast-in-place beam 9, so that the first base 201 and the second base 202 are separated from the cast-in-place beam 9. After removing the first base 201 and the second base 202, the construction personnel dismantle the cross beam 1.
