As shown in fig. 1 to 4, a beam moving device includes a base 1, a jacking assembly, a first driving assembly 5, and a second driving assembly 6.
The base body 1 comprises a first sliding surface 11; the jacking assembly comprises a first sliding mechanism 2 arranged on the base body 1 in a sliding mode, and a vertical jacking device 3 and a second sliding mechanism 4 which are fixedly connected, specifically, the first sliding mechanism 2 is arranged on a first sliding surface 11, and the first sliding mechanism 2 and the first sliding surface 11 can be kept relatively fixed and can also move relatively along a first direction.
The first sliding mechanism 2 has a second sliding surface 21 on one side, and the second sliding mechanism 4 is provided on the second sliding surface 21, so that the second sliding mechanism 4 and the second sliding surface 21 can be held relatively fixed or can be moved relatively in the second direction.

The first direction is different from the second direction, and the vertical jacking device 3 can drive the beam body to slide along the second direction or the first direction through the sliding process of the vertical jacking device 3 along the second direction and the first direction, so that the deviation correction of the moving beam in multiple directions is finally realized.
The vertical jacking device 3 can be a jack device, and has simple structure and good bearing.
The first embodiment.
As shown in fig. 1 to 4, the first sliding mechanism 2 includes a first limiting portion 22 for limiting the second direction, and in a state where the vertical jacking device 3 slides in 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; in the state that the vertical jacking device 3 slides along the second direction, the first limiting part 22 is unlocked so that the first sliding mechanism 2 and the second sliding mechanism 4 can move relatively; it should be understood that the second direction refers to one of the beam moving directions pre-designed in the specific implementation and is defined by the first position-limiting portion 22, so the second direction may be the axial direction or the extending direction of the first position-limiting portion 22 itself, or may be another direction.
The first sliding mechanism 2 is provided with two convex parts which protrude out of the second sliding surface 21 and are arranged at intervals, the two convex parts and the second sliding surface 21 jointly enclose a guide groove which extends along a first direction, the guide groove is a first limiting part 22, the second sliding mechanism 4 is adaptively embedded into the first limiting part 22, when the sliding trend of the second sliding mechanism 4 relative to the first sliding mechanism 2 is the first direction, the groove wall of the first limiting part 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, the second sliding mechanism 4 is ensured to slide along the second direction relative to the first sliding mechanism 2, and the beam moving device is realized in the mode that the beam moving device is arranged on the beam moving device
And a second direction deviation rectifying function.
Under the sliding of the first position-limiting part 22 in the second direction, the first direction also needs to be further limited. The maximum static friction force between the first sliding mechanism 2 and the base body 1 is F1, the maximum static friction force between the second sliding mechanism 4 and the first sliding mechanism 2 is F2, and F2 < F1 can be adopted in the embodiment to limit to the first direction; the limitation here means that in a state where the vertical jacking device 3 is along 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 body 1 are relatively fixed.
Specifically, as shown in fig. 1 to 3, when the first sliding mechanism 2 has a sliding tendency along a first direction relative to the base 1 under the driving of the first driving assembly 5, that is, the vertical jacking device 3 is 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 no displacement and no friction occur between the first sliding mechanism and the second sliding mechanism, the first driving assembly 5 only needs to provide an acting force F3 to overcome the F1, so that the first sliding mechanism 2 can slide back and forth relative to the base 1 along the first direction, and 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 jacking device 3, and finally drives the beam body to slide along the first direction, thereby achieving deviation rectification along the first direction;
similarly, when the second sliding mechanism 4 is driven by the second driving assembly 6 to have a sliding tendency along the second direction relative to the first sliding mechanism 2, that is, the vertical jacking device 3 is along the second direction, the first limiting part 22 is unlocked, the first sliding mechanism 2 and the second sliding mechanism 4 move relatively, and the relative movement here means that the sliding mechanism can slide along the second direction;
a friction force F2 'exists between the first sliding mechanism 2 and the second sliding mechanism 4, the second driving assembly 6 can apply an acting force F4 to the second sliding mechanism 4 to overcome the friction force F2' to slide, and the first sliding mechanism 2 movably disposed on the first sliding surface 11 is respectively subjected to the friction force F2 'acting on the first 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 relative to the first sliding mechanism 2 along the second direction, so that the second sliding mechanism 4 drives the vertical jacking device 3, and finally, the sliding of the beam body along the second direction is realized, and the deviation correction in the second direction is realized.
It can be understood that when the force F4 is equal to or slightly greater than the friction force F2 ', the second sliding mechanism 4 can be pushed to slide in the second direction, and as the value of F2 ' is greater, the friction force F1 ' needs to be correspondingly increased to ensure that the first sliding mechanism 2 is stationary relative to the base 1, the first direction can be defined only by designing the maximum static friction force F1 > the maximum static friction force F2, and when F2 ' reaches the maximum (i.e., 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, and F1 ' ═ F2 ' ═ F2 < F1, so that the sliding of the second sliding mechanism 4 relative to the first sliding mechanism 2 in the second direction can be smoothly achieved.
On the premise of satisfying F2 < F1. For the engagement between the base body 1 and the first sliding mechanism 2, a corresponding plane, concave-convex, damped wheel body may be provided on the first sliding mechanism 2 to engage the first sliding surface 11 for sliding, and a suitable friction material, such as a lubricant filled with silicone oil, graphite powder, etc., may be added thereto to obtain a suitable friction coefficient, so-called suitable, i.e., F2 < F1 and the friction coefficient between the base body 1 and the first sliding mechanism 2 should be as small as possible to reduce the load on the first drive assembly 5. For the matching between the second sliding mechanism 4 and the first sliding mechanism 2, a corresponding smooth plane, pulley or slider may be provided on the second sliding mechanism 4 to match the second sliding surface 21 for sliding, and a suitable friction-resisting material, such as a lubricant filled with silicone oil, graphite powder, etc., may be added thereto, so as to obtain a smaller friction coefficient.
Example two
As shown in fig. 4 and 5, the first sliding mechanism 2 includes a second limiting portion 23 for limiting the first direction, and in a state where the vertical lifting device 3 slides in the second direction, the second limiting portion 23 is locked so that the first sliding mechanism 2 is fixed relative to the base 1; in the state that the vertical jacking device 3 slides along the first direction, the second limiting part 23 is unlocked, so that the first sliding mechanism 2 and the base body 1 move relatively. It should be understood that the first direction refers to one of the beam moving directions pre-designed in the specific implementation and is defined by the second limiting portion 23, so the first direction may be the axial direction or the extending direction of the second limiting portion 23 itself, or may be another direction.
The first sliding mechanism 2 is formed with two hook members protruding out of the bottom end face of the first sliding mechanism 2, the hook members are arranged at intervals, the two hook members and the bottom end face of the first sliding mechanism 2 jointly enclose a sliding groove extending along the first direction, the sliding groove can be in a T shape, the sliding groove serves as a second limiting portion 23, and the base body 1 is adaptively embedded into the second limiting portion 23. The base body 1 includes a guide portion 12, and the guide portion 12 and the second limiting portion 23 cooperate together to provide sliding guidance of the first sliding mechanism 2 relative to the base body 1 along the first direction, and prevent the first sliding mechanism 2 from being separated from the base body 1 under an external force, so as to ensure safety. When the sliding trend of the first sliding mechanism 2 relative to the base body 1 is the second direction, the hook member of the second limiting portion 23 can hook the base body 1, so that the first sliding mechanism 2 and the base body 1 are relatively fixed, and the first sliding mechanism 2 is ensured to only slide along the first direction relative to the base body 1, so that the deviation rectifying function of the beam moving device in the first direction is realized.
Further limitation is required in the second direction as well, provided that the second stopper portion 23 limits the sliding movement in the first direction. The maximum static friction force between the first sliding mechanism 2 and the base body 1 is F1, the maximum static friction force between the second sliding mechanism 4 and the first sliding mechanism 2 is F2, and F2 is not less than F1 in the embodiment to limit the second direction; the limitation here means that, in a state where the vertical jacking device 3 is along 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.
Specifically, as shown in fig. 5, when the first sliding mechanism 2 has a sliding tendency along the second direction relative to the base 1 under the driving of the second driving assembly 6, that is, the vertical jacking device 3 is along the second direction, the second limiting portion 23 is locked, so that the first sliding mechanism 2 and the base 1 are relatively fixed, no displacement occurs between the first sliding mechanism 2 and the base 1, and no friction exists between the first sliding mechanism and the base, the second driving assembly 6 only needs to provide an acting force F5 to overcome the F2, so that the second sliding mechanism 4 can slide in a reciprocating manner along the second direction relative to the first sliding mechanism 2, and the second sliding mechanism 4 drives the vertical jacking device 3, so as to finally drive the beam to slide along the second direction, thereby achieving deviation rectification in the second direction;
similarly, when the first sliding mechanism 2 is driven by the first driving assembly 5 to have a sliding tendency along the first direction relative to the first sliding mechanism 2, that is, the vertical jacking device 3 is unlocked along the first direction by the first limiting part 22, the first sliding mechanism 2 and the base 1 move relatively, and the relative movement here means that the first sliding mechanism can slide along the second direction;
the first driving assembly 5 may apply an acting force F6 to the second sliding mechanism 4 to be transmitted to the first sliding mechanism 2 to overcome the frictional force F1 ' so as to enable the second sliding mechanism 4 to slide, while the second sliding mechanism 4 movably disposed on the second sliding surface 21 is respectively subjected to the frictional force F2 ' and the acting force F6 acted on the second 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 back and forth relative to the base 1 in the first direction, the first sliding mechanism 2 slides synchronously with the second sliding mechanism 4, the second sliding mechanism 4 slides synchronously with the vertical jacking device 3, and finally, the sliding of the beam body in the first direction is realized, and the deviation correction in the first direction is realized.
It can be understood that when the 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, and as the value of F1 ' is greater, the friction force F2 ' needs to be correspondingly increased to ensure that the second sliding mechanism 4 is stationary relative to the first sliding mechanism 2, the second direction can be defined only by designing the maximum static friction force F2 > the maximum static friction force F1, and when F1 ' reaches the maximum (i.e., 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, and F2 ≧ F2 ': F1 ' ═ F1, so that the sliding of the first sliding mechanism 2 relative to the base body 1 along the first direction can be successfully realized.
In the third embodiment, as shown in fig. 4, 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, in a state where the vertical jacking device 3 slides in the first direction, the first limiting portion 22 is locked to relatively fix the first sliding mechanism 2 and the second sliding mechanism 4, and the first limiting portion 22 is unlocked to relatively move the first sliding mechanism 2 and the base 1; in the state that the vertical jacking device 3 slides along the second direction, the first limiting part 22 is unlocked to enable the first sliding mechanism 2 and the second sliding mechanism 4 to move relatively, and the second limiting part 23 is locked to enable the first sliding mechanism 2 and the base body 1 to be relatively fixed;
for a specific process, reference may be made to portions of the first limiting portion 22 and the second limiting portion 23 corresponding to the first limiting portion and the second limiting portion in the first and second embodiments, which are not described herein again. The deviation rectifying function of the beam moving device in the first direction and the second direction is achieved through effective limitation of the first direction and the second direction.
In a possible implementation manner, the second direction and the first direction are generally arranged at an included angle, so that the vertical jacking device 3 can conveniently slide along a specified direction in a plane range through the first sliding mechanism 2 and the second sliding mechanism 4, and deviation rectification in the plane range is realized; the second direction is generally perpendicular to the first direction to facilitate adjustment of the position.
In a possible embodiment, as shown in fig. 1 and 2, the first driving assembly 5 includes at least two opposite driving mechanisms 51, the driving mechanisms 51 may be jacks, a first end of each driving mechanism 51 is fixed to the base 1, and second ends of the two driving mechanisms 51 respectively abut against the jacking assembly from two opposite directions, which are two directions along the same axis and are opposite to each other, and the moment arm is zero, so as to avoid forming a moment. It is understood that the interference part may be one or more of the first sliding mechanism 2, the vertical jacking device 3 or the second sliding mechanism 4; the jacking directions of the two driving mechanisms 51 are on the same axis to avoid forming moment; the jacking assembly slides along a first direction, one driving mechanism 51 pushes against the jacking assembly to exert thrust, the other opposite driving mechanism 51 retracts to provide a space for the jacking assembly to slide transversely, the vertical jacking device 3 slides along the first direction, so that the second sliding mechanism 4 slides along the first direction, the first limiting part 22 locks the first sliding mechanism 2 and the second sliding mechanism 4 to be fixed relatively, and the first sliding mechanism 2 slides on the first sliding surface 11 along the first direction.
In a possible embodiment, as shown in fig. 3, the beam moving device includes two or more groups of connecting plates 7, the number of the jacking assemblies is two or more, and the adjacent vertical jacking devices 3 are fixedly connected through the connecting plates 7, specifically, the connecting plates 7 can be directly connected with the vertical jacking devices 3, and also can be connected with the second sliding mechanisms 4 in the jacking assemblies, so that the vertical jacking devices 3 can slide along the second direction or the first direction together.
The first driving assembly 5 comprises at least two driving mechanisms 51, and a first end of each driving mechanism 51 is fixed with the base body 1; the second end of the driving mechanism 51 abuts against the corresponding jacking assembly, and specifically, the abutting part may be the first sliding mechanism 2, the vertical jacking device 3 or the second sliding mechanism 4.
It should be understood that, because the adjacent vertical jacking devices 3 are fixed, the number of the jacking assemblies is not consistent with the number of the driving mechanisms 51, and it is ensured that the driving directions of at least two groups of driving mechanisms 51 are opposite to each other, wherein one group of first driving assemblies 5 acts on one group of jacking assemblies from the forward direction of the second direction, the other group of first driving assemblies 5 acts on the other group of jacking assemblies from the reverse direction of the second direction, and the vertical jacking devices 3 of the two groups of jacking assemblies are directly or indirectly fixedly connected into a whole by the connecting plate 7.
In a possible embodiment, as shown in fig. 1 to 4, a first end of the second driving assembly 6 is fixedly connected to the first sliding mechanism 2, a second end of the second driving assembly 6 is fixedly connected to the vertical lifting device 3 or the second sliding mechanism 4, and when the second driving assembly 6 is lifted or retracted, the vertical lifting device 3 can slide in the second direction relative to the first sliding mechanism 2. The second drive assembly 6 may be a jack device; the first sliding mechanism 2 includes a second blocking wall 24 for receiving the force of the second driving assembly 6, and specifically, the first end of the second driving assembly 6 can be fixedly connected to the first blocking wall 13 to receive the force.
It can be understood that if the first driving assembly 5 is in interference connection with the jacking assembly, when the second driving assembly 6 moves the vertical jacking device 3, the first driving assembly 5 should be retracted in advance, so that the first driving assembly 5 is separated from the jacking assembly so as not to interfere with the sliding of the second driving assembly 6.
