Description

Technical Field

[0001] The present application relates to railway bridge repair technology, and in particular to a beam shifting device. Background Art

[0002] Bridges are an important form of transportation in my country. Severe deformation of bridge bearings, slight bulging, partial hollowing, etc. can cause the bridge beam to shift horizontally or vertically, causing damage to the structure on the beam or the bridge structure cannot meet the functional requirements. In this case, the beam needs to be moved and restored. In the prior art, temporary bearings are usually set between the beam and the piers to transfer the weight of the beam to the piers through the temporary bearings, and then jacks, sliding surfaces and reaction facilities are set on the piers to move the beam.

[0003] The reaction equipment is generally a reaction pier or a reaction steel frame fixed on the pier. The reaction pier is a concrete structure fixed to the pier by embedding or expansion bolts; the reaction steel frame is a steel structure fixed to the pier by embedding or expansion bolts. When moving the beam, a sliding surface is set on the jack, and the reaction equipment is used to provide reaction force to move the beam. After the construction is completed, the reaction pier or reaction steel frame is removed. The general reaction device only provides reaction force in one direction. If it is necessary to provide reaction forces in multiple directions, such as horizontal and vertical directions, multiple reaction devices need to be set up, which makes the construction and installation more complicated. In addition, the reaction equipment needs to be fixed and removed on the pier, which causes varying degrees of damage to the pier. Summary of the invention

[0009] Furthermore, the maximum static friction force between the first sliding mechanism and the base is F1, and the maximum static friction force between the second sliding mechanism and the first sliding mechanism is F2, and F2<F1, so that when the vertical jacking device is in a state along the second direction, the first sliding mechanism and the second sliding mechanism are relatively movable, and the first sliding mechanism and the base are relatively fixed.

[0011] Further, the first sliding mechanism is formed with two hooks protruding from the bottom end surface of the first sliding mechanism, and the two hooks and the bottom end surface of the first sliding mechanism together form a slide groove extending along the first direction as the second limiting portion, and the base is adaptively embedded in the second limiting portion.

[0012] Furthermore, the maximum static friction force between the first sliding mechanism and the base is F1, the maximum static friction force between the second sliding mechanism and the first sliding mechanism is F2, and F2≥F1, so that when the vertical jacking device is in a state along the first direction, the first sliding mechanism and the second sliding mechanism are relatively fixed, and the first sliding mechanism and the base are relatively movable.

[0013] Furthermore, the first driving assembly includes at least two driving mechanisms arranged opposite to each other, the first ends of the driving mechanisms are fixed to the base, and the second ends of the two driving mechanisms respectively abut against the lifting assembly from two opposite directions.

[0025] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed descriptions in the specific implementation methods should be understood as explanations of the present application and should not be regarded as improper limitations on the present application.

[0026] In the description of the embodiments of the present application, the directions or positional relationships of "up", "down", "left", "right", "front", and "rear" are based on the attached Figure 1 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] A general multi-directional beam-moving device for reaction force is usually claimed to have a vertical jack and a plurality of horizontally arranged driving devices. The vertical jack is used to lift the beam of the bridge so that the beam is separated from the pier. The vertical jack is then driven by driving devices along different directions respectively, so that the vertical jack can drive the beam to move horizontally. The direction of movement can be lateral or longitudinal. The longitudinal displacement is the relative movement of the first component and the second component, and the lateral displacement is the relative movement of the second component and the third component. The vertical jack is arranged on the first component, and the third component is the base. However, the three components are movably connected to each other. How to ensure that the second component can move relative to the third component in the state of lateral movement and no longitudinal displacement occurs (that is, the first component and the second component are required to be relatively fixed during lateral movement and become relatively movable during longitudinal movement) is not explained. The first component and the second component also have the same problem. Therefore, the scheme is incomplete and cannot be implemented.

[0028] like Figures 1 to 4 As shown, a beam moving device includes a base 1, a lifting assembly, a first driving assembly 5 and a second driving assembly 6.

[0029] The base 1 includes a first sliding surface 11; the lifting assembly includes a first sliding mechanism 2 slidingly arranged on the base 1, and a vertical lifting device 3 and a second sliding mechanism 4 fastened to each other. Specifically, the first sliding mechanism 2 is arranged on the first sliding surface 11, and the first sliding mechanism 2 and the first sliding surface 11 can remain relatively fixed or can move relatively along the first direction.

[0030] The first sliding mechanism 2 has a second sliding surface 21 on which the second sliding mechanism 4 is disposed. The second sliding mechanism 4 and the second sliding surface 21 can be relatively fixed or relatively movable along a second direction. Usually, the second sliding surface 21 is the side of the first sliding mechanism 2 that is away from the base 1.

[0031] One end of the vertical lifting device 3 is supported on the second sliding mechanism 4, and the other end of the vertical lifting device 3 is used to support the beam body (not shown).

[0032] The first driving component 5 is used to drive the vertical lifting device 3 to slide along the first direction relative to the base 1; wherein, when the vertical lifting device 3 slides back and forth along the first direction, the first sliding mechanism 2 and the second sliding mechanism 4 are relatively fixed, and the first sliding mechanism 2, the vertical lifting device 3 and the second sliding mechanism 4 form a whole. The first driving component 5 can drive one or more of the first sliding mechanism 2, the vertical lifting device 3 or the second sliding mechanism 4 to slide. Taking the first driving component 5 directly driving the vertical lifting device 3 as an example, the vertical lifting device 3 transmits the sliding trend along the first direction to the second sliding mechanism 4, and the second sliding mechanism 4 transmits it to the first sliding mechanism 2, and the first sliding mechanism 2 is set to move relative to the base 1, so as to realize the first sliding mechanism 2 sliding along the first direction on the first sliding surface 11, thereby completing the process of reciprocating sliding of the vertical lifting device 3 relative to the base 1 along the first direction.

[0033] Similarly, the second driving component 6 is used to drive the vertical jacking device 3 to slide along the second direction relative to the first sliding mechanism 2; wherein, when the vertical jacking device 3 slides back and forth along the second direction, the first sliding mechanism 2 and the second sliding mechanism 4 move relatively, and the vertical jacking device 3 and the second sliding mechanism 4 form a whole. The second driving component 6 can drive the vertical jacking device 3 or one of the second sliding mechanisms 4 to slide. Taking the second driving component 6 directly driving the vertical jacking device 3 as an example, the vertical jacking device 3 transmits the sliding trend along the second direction to the second sliding mechanism 4, and the first sliding mechanism 2 is set to be relatively fixed to the base 1, so as to realize the second sliding mechanism 4 sliding along the second direction on the second sliding surface 21, thereby completing the process of the vertical jacking device 3 sliding back and forth relative to the base 1 along the second direction.

[0034] The first direction is different from the second direction. Through the sliding process of the vertical lifting device 3 along the second direction and the first direction, the vertical lifting device 3 can drive the beam body to slide along the second direction or the first direction, and finally realize beam shifting and deviation correction in multiple directions.

[0035] The vertical lifting device 3 can be a jack device, which has a simple structure and good load-bearing capacity.

[0036] Embodiment 1

[0037] like Figures 1 to 4As shown, the first sliding mechanism 2 includes a first limiting portion 22 for limiting the second direction. When the vertical lifting device 3 slides along the first direction, the first limiting portion 22 is locked so that the first sliding mechanism 2 and the second sliding mechanism 4 are relatively fixed; when the vertical lifting device 3 slides along the second direction, the first limiting portion 22 is unlocked so that the first sliding mechanism 2 and the second sliding mechanism 4 are relatively movable; it should be understood that the second direction refers to one of the beam shifting directions pre-designed in the specific implementation and is limited by the first limiting portion 22. Therefore, the second direction can be the axial direction or extension direction of the first limiting portion 22 itself, or it can be other directions.

[0038] The first sliding mechanism 2 is formed with two convex portions protruding from the second sliding surface 21 and arranged at intervals. The two convex portions and the second sliding surface 21 together form a guide groove extending along the first direction. The guide groove is the first limiting portion 22. The second sliding mechanism 4 is adaptively embedded in the first limiting portion 22. When the sliding trend of the second sliding mechanism 4 relative to the first sliding mechanism 2 is in the first direction, the groove wall of the first limiting portion 22 is limited by the second sliding mechanism 4, so that the first sliding mechanism 2 and the second sliding mechanism 4 are relatively fixed, thereby ensuring that the second sliding mechanism 4 can only slide along the second direction relative to the first sliding mechanism 2, thereby realizing the deviation correction function of the beam shifting device in the second direction.

[0039] When the first limit portion 22 limits the sliding in the second direction, further limitations are also required in the first direction. The maximum static friction between the first sliding mechanism 2 and the base 1 is F1, and the maximum static friction between the second sliding mechanism 4 and the first sliding mechanism 2 is F2. In this embodiment, F2<F1 can be used to limit the first direction; the limitation here refers to the state that when the vertical lifting device 3 is in the second direction, the first sliding mechanism 2 and the second sliding mechanism 4 are relatively movable, and the first sliding mechanism 2 and the base 1 are relatively fixed.

[0040] Specifically, Figures 1 to 3 As shown, when the first sliding mechanism 2 has a sliding tendency along the first direction relative to the base 1 under the drive of the first driving component 5, that is, the vertical lifting device 3 is along the first direction, the first limit portion 22 is locked, so that the first sliding mechanism 2 and the second sliding mechanism 4 are relatively fixed, and no displacement occurs between the two, and there is no friction. The first driving component 5 only needs to provide an action force F3 to overcome F1 to make the first sliding mechanism 2 reciprocate relative to the base 1 along the first direction. Then, the first sliding mechanism 2 drives the second sliding mechanism 4 to slide together along the first direction, and the second sliding mechanism 4 drives the vertical lifting device 3, and finally drives the beam body to slide along the first direction, and realizes the correction in the first direction;

[0041] Similarly, when the second sliding mechanism 4 has a sliding tendency along the second direction relative to the first sliding mechanism 2 under the drive of the second driving assembly 6, that is, the vertical lifting device 3 is along the second direction, the first limit portion 22 is unlocked, and the first sliding mechanism 2 and the second sliding mechanism 4 are relatively movable. The relative movable here refers to being able to slide along the second direction;

[0042] There is a friction force F2' between the first sliding mechanism 2 and the second sliding mechanism 4. The second driving component 6 can apply a force F4 to the second sliding mechanism 4 to overcome the friction force F2' and slide. The first sliding mechanism 2 movably arranged on the first sliding surface 11 is respectively subjected to the friction force F2' from the second sliding mechanism 4 and the friction force F1' between the first sliding mechanism 2 and the base 1, and F2'=F1', so that the first sliding mechanism 2 is stationary relative to the base 1, and the second sliding mechanism 4 slides back and forth along the second direction relative to the first sliding mechanism 2, so that the second sliding mechanism 4 drives the vertical jacking device 3, and finally realizes the sliding of the beam body along the second direction, and realizes the correction in the second direction.

[0043] It can be understood that when the action force F4 is equal to or slightly greater than the friction force F2', the second sliding mechanism 4 can be pushed to slide along the second direction. As the value of F2' increases, the friction force F1' also needs to increase accordingly to ensure that the first sliding mechanism 2 is stationary relative to the base 1. It is only necessary to design the maximum static friction force F1> the maximum static friction force F2 to limit the first direction. When F2' reaches the maximum (that is, the maximum static friction force F2), the friction force F1' can still meet the condition that the first sliding mechanism 2 is stationary relative to the base 1, F1'=F2'=F2<F1, so that the second sliding mechanism 4 can slide smoothly along the second direction relative to the first sliding mechanism 2.

[0044] Under the premise of satisfying F2<F1. For the cooperation between the base 1 and the first sliding mechanism 2, a corresponding plane, concave-convex surface, and a wheel with damping can be set on the first sliding mechanism 2 to cooperate with the first sliding surface 11 to achieve sliding, and a suitable friction material can be added therein, such as filling silicone oil, graphite powder and other lubricants, so as to obtain a suitable friction coefficient. The so-called suitable means that F2<F1 and the friction coefficient between the base 1 and the first sliding mechanism 2 should be as small as possible to reduce the load of the first driving component 5. For the cooperation between the second sliding mechanism 4 and the first sliding mechanism 2, a corresponding smooth plane, pulley or slider can be set on the second sliding mechanism 4 to cooperate with the second sliding surface 21 to achieve sliding, and a suitable friction material can be added therein, such as filling silicone oil, graphite powder and other lubricants, so as to obtain a smaller friction coefficient.

[0045] Embodiment 2

[0046] like Figure 4 and Figure 5 As shown, the first sliding mechanism 2 includes a second limiting portion 23 for limiting the first direction. When the vertical lifting device 3 slides along the second direction, the second limiting portion 23 is locked so that the first sliding mechanism 2 is relatively fixed to the base 1; when the vertical lifting device 3 slides along the first direction, the second limiting portion 23 is unlocked so that the first sliding mechanism 2 is relatively movable to the base 1. It should be understood that the first direction refers to one of the beam shifting directions pre-designed in the specific implementation and is limited by the second limiting portion 23. Therefore, the first direction can be the axial direction or extension direction of the second limiting portion 23 itself, or other directions.

[0047] The first sliding mechanism 2 is formed with two hooks protruding from the bottom end surface of the first sliding mechanism 2, and the hooks are arranged at intervals. The two hooks and the bottom end surface of the first sliding mechanism 2 together form a slide groove extending along the first direction. The slide groove can be T-shaped, and the slide groove is used as the second limiting portion 23. The base 1 is adaptively embedded in the second limiting portion 23. The adaptation here means that the base 1 includes a guide portion 12, and the guide portion 12 cooperates with the second limiting portion 23 to provide a sliding guide for the first sliding mechanism 2 relative to the base 1 along the first direction, and prevents the first sliding mechanism 2 from detaching from the base 1 under external force to ensure safety. When the sliding tendency of the first sliding mechanism 2 relative to the base 1 is the second direction, the hook of the second limiting portion 23 can hook the base 1, so that the first sliding mechanism 2 is relatively fixed with the base 1, thereby ensuring that the first sliding mechanism 2 can only slide along the first direction relative to the base 1, thereby realizing the deviation correction function of the beam shifting device in the first direction.

[0048] Under the premise that the second limiter 23 limits the sliding in the first direction, further limitations are also required in the second direction. The maximum static friction between the first sliding mechanism 2 and the base 1 is F1, and the maximum static friction between the second sliding mechanism 4 and the first sliding mechanism 2 is F2. In this embodiment, F2≥F1 can be used to limit the second direction; the limitation here means that when the vertical lifting device 3 is in the first direction, the first sliding mechanism 2 and the second sliding mechanism 4 are relatively fixed, and the first sliding mechanism 2 and the base 1 are relatively movable.

[0049] Specifically, Figure 5 As shown, when the first sliding mechanism 2 has a sliding tendency along the second direction relative to the base 1 under the drive of the second driving component 6, that is, the vertical lifting device 3 is along the second direction, the second limit portion 23 is locked, so that the first sliding mechanism 2 and the base 1 are relatively fixed, and no displacement occurs between the two, and there is no friction. The second driving component 6 only needs to provide a force F5 to overcome F2 to make the second sliding mechanism 4 reciprocate relative to the first sliding mechanism 2 along the second direction. The second sliding mechanism 4 drives the vertical lifting device 3, and finally drives the beam body to slide along the second direction, and realizes the correction in the second direction;

[0050] Similarly, when the first sliding mechanism 2 has a sliding tendency along the first direction relative to the first sliding mechanism 2 under the drive of the first driving assembly 5, that is, the vertical lifting device 3 is along the first direction, the first limit portion 22 is unlocked, and the first sliding mechanism 2 and the base 1 are relatively movable. The relative movable here refers to being able to slide along the second direction;

[0051] The friction force F1' between the first sliding mechanism 2 and the base 1, the first driving component 5 can apply an action force F6 to the second sliding mechanism 4 to be transmitted to the first sliding mechanism 2 to overcome the friction force F1' so as to realize the sliding of the second sliding mechanism 4, and the second sliding mechanism 4 movably arranged on the second sliding surface 21 is respectively subjected to the friction force F2' and the action force F6 from the first sliding mechanism 2, and F2'=F6, so that the second sliding mechanism 4 is stationary relative to the first sliding mechanism 2, and the first sliding mechanism 2 slides reciprocatingly along the first direction relative to the base 1, the first sliding mechanism 2 slides synchronously with the second sliding structure 4, and the second sliding mechanism 4 slides synchronously with the vertical jacking device 3, finally realizing the sliding of the beam body along the first direction and realizing the deviation correction in the first direction.

[0052] It can be understood that when the action force F6 is equal to or slightly greater than the friction force F1', the first sliding mechanism 2 can be pushed to slide along the first direction. As the value of F1' increases, the friction force F2' also needs to increase accordingly to ensure that the second sliding mechanism 4 is stationary relative to the first sliding mechanism 2. It is only necessary to design the maximum static friction force F2> the maximum static friction force F1 to limit the second direction. When F1' reaches the maximum (that is, the maximum static friction force F1), the friction force F2' can still meet the condition that the second sliding mechanism 4 is stationary relative to the first sliding mechanism 2, F2≥F2'=F1'=F1, so that the first sliding mechanism 2 can slide smoothly relative to the base 1 along the first direction.

[0053] Embodiment 3

[0054] like Figure 4 As shown, the first sliding mechanism 2 includes a first limiting portion 22 for limiting the second direction and a second limiting portion 23 for limiting the first direction. When the vertical lifting device 3 slides along the first direction, the first limiting portion 22 is locked so that the first sliding mechanism 2 and the second sliding mechanism 4 are relatively fixed, and the first limiting portion 22 is unlocked so that the first sliding mechanism 2 and the base 1 are relatively movable; when the vertical lifting device 3 slides along the second direction, the first limiting portion 22 is unlocked so that the first sliding mechanism 2 and the second sliding mechanism 4 are relatively movable, and the second limiting portion 23 is locked so that the first sliding mechanism 2 and the base 1 are relatively fixed;

[0055] The specific process can refer to the parts corresponding to the first limiter 22 and the second limiter 23 in the first and second embodiments, which will not be repeated here. By effectively limiting the first direction and the second direction, the deviation correction function of the beam shifting device in the first direction and the second direction is realized.

[0056] In a possible embodiment, the second direction and the first direction are generally set at an angle to facilitate the vertical jacking device 3 to slide along the specified direction within the plane through the first sliding mechanism 2 and the second sliding mechanism 4 to achieve correction within the plane; the second direction is usually set perpendicular to the first direction to facilitate position adjustment.

[0057] In a possible implementation, Figure 1 and Figure 2 As shown, the first driving assembly 5 includes at least two driving mechanisms 51 set up opposite to each other. The driving mechanism 51 can be a jack. The first end of the driving mechanism 51 is fixed to the base 1. The second ends of the two driving mechanisms 51 respectively contact the lifting assembly from two opposite directions. The two directions refer to two directions along the same axis, which are opposite and have zero force arm to avoid forming a moment. It can be understood that the contacting part can be one or more of the first sliding mechanism 2, the vertical lifting device 3 or the second sliding mechanism 4; the lifting directions of the two driving mechanisms 51 are on the same axis to avoid forming a moment; sliding along the first direction, one driving mechanism 51 presses on the lifting assembly to apply thrust, and the other relative driving mechanism 51 retracts to provide space for the lifting assembly to slide horizontally, the vertical lifting device 3 slides along the first direction, so that the second sliding mechanism 4 slides along the first direction, the first limit portion 22 locks the first sliding mechanism 2 and the second sliding mechanism 4 to be relatively fixed, and the first sliding mechanism 2 slides on the first sliding surface 11 along the first direction.

[0058] In a possible implementation, Figure 3 As shown, the beam shifting device includes a connecting plate 7, the number of jacking assemblies is more than two groups, and adjacent vertical jacking devices 3 are fixedly connected by the connecting plate 7. Specifically, the connecting plate 7 can be directly connected to the vertical jacking device 3, or it can be connected to the second sliding mechanism 4 in the jacking assembly, so that the vertical jacking device 3 slides together along the second direction or the first direction.

[0059] The first driving assembly 5 includes at least two driving mechanisms 51, the first ends of the driving mechanisms 51 are fixed to the base 1; the second ends of the driving mechanisms 51 abut against the corresponding lifting components, specifically, the abutting parts can be the first sliding mechanism 2, the vertical lifting device 3 or the second sliding mechanism 4.

[0060] It should be understood that, since the adjacent vertical jacking devices 3 have been fixed, the number of jacking components and the driving mechanism 51 are not necessarily the same. It is sufficient to ensure that the driving directions of at least two groups of driving mechanisms 51 are opposite to each other, one group of first driving components 5 acts on one group of jacking components from the positive direction of the second direction, and the other group of first driving components 5 acts on the other group of jacking components from the reverse direction of the second direction. The vertical jacking devices 3 of the two groups of jacking components are directly or indirectly fixedly connected as a whole by means of a connecting plate 7.

[0061] In a possible implementation, Figures 1 to 4 As shown, the first end of the second drive assembly 6 is fixedly connected to the first sliding mechanism 2, and the second end of the second drive assembly 6 is fixedly connected to the vertical jacking device 3 or the second sliding mechanism 4. When the second drive assembly 6 is lifted or retracted, the vertical jacking device 3 can slide along the second direction relative to the first sliding mechanism 2. The second drive assembly 6 can be a jack device; the first sliding mechanism 2 includes a second retaining wall 24 for the second drive assembly 6 to bear force. Specifically, the first end of the second drive assembly 6 can be fixedly connected to the first retaining wall 13 to facilitate the force.

[0062] It is understandable that if the first drive assembly 5 is connected in an interference manner with the lifting assembly, when the second drive assembly 6 moves the vertical lifting device 3, the first drive assembly 5 should be retracted in advance to separate the first drive assembly 5 from the lifting assembly to avoid interfering with the sliding of the second drive assembly 6.

[0063] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0064] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
