Detailed Description
The present invention will be described in further detail with reference to specific embodiments in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As required, detailed embodiments of the present invention are disclosed in the present specification; however, it is to be understood that the embodiments disclosed herein are merely exemplary of the invention that may be embodied in various and alternative forms. In the following description, a number of operating parameters and components are described in terms of various embodiments contemplated. These specific parameters and components are presented as examples and are not meant to be limiting.
It should be noted that, in the following description, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the apparatus or element to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Fig. 1 and 2 are schematic diagrams of an active wheel set of a bridge crane, wherein fig. 1 is a front view and fig. 2 is a side view. As shown in fig. 1 and 2, the active wheel set 1 of the bridge crane comprises two wheels 3 connected together by a drive wheel balance beam 2, each wheel 3 comprising a respective axle 4, wheel shoe 6, wheel bearing cap 7, etc. Due to the presence of the axle 4 and the coupling (not shown), the driving wheel set 1 is not symmetrical in the transverse direction X, which is prone to toppling over during movement due to weight bias.
Fig. 3 is a schematic diagram of a conventional replacement operation of a driving wheel set of a bridge crane. Firstly, after the driving wheel set 1 is detached from the bridge crane body A, 4 pieces of 3 tons of chain blocks 8 and 6 persons are required to perform cooperation operation so as to be dumped from the body A along the track surface B in the direction indicated by an arrow C. Because the supporting point of the driving wheel set 1 is a line (track) instead of a surface, and 6 operators have the problems of uneven traction and uneven force, the stability of the driving wheel set 1 in the moving process is difficult to control, and the driving wheel set is easy to incline. The current operation mode of the driving wheel set cannot meet the efficiency and safety requirements.
In view of this problem, it is an object of the present invention to provide a wheel anti-toppling device, so as to assist in stabilizing an active wheel set when changing the active wheel set, and prevent toppling.
According to a first aspect of the present invention, there is provided a wheel anti-toppling device. Fig. 4 and fig. 5 are schematic diagrams of a wheel anti-toppling device according to an embodiment of the present invention. As shown, the wheel anti-toppling device 10 includes a first support frame 20, a second support frame 30, and a link mechanism 40. The first support frame 20 comprises a first base 21 extending in the longitudinal direction Y, a lifting mechanism 22 arranged on the first base 21, and an axle supporting member 23 arranged above the lifting mechanism 21, the axle supporting member 23 being for supporting an axle of a wheel, for example the axle 4 of the above-mentioned active wheel set. Wheels 24 are provided under the first base 21. The second support frame 30 comprises a second base 31 extending in the longitudinal direction Y, below which second base 31 wheels 32 are arranged. The linkage 40 extends in the transverse direction X and connects the first support frame 20 and the second support frame 30 together.

Specifically, in the illustrated embodiment, the first link 41 and the second link 42 are respectively engaged with the first support frame 20 and the second support frame 30. In other embodiments, the linkage 40 may take other forms that conveniently connect the first support bracket 20 and the second support bracket 30.
Fig. 6 is an isolated schematic view of the first support frame 20. In the embodiment shown, two sets of wheels 24 are provided below the first base 21, each set having two wheels, each set being secured below the first base 21 by a wheel carrier. In the illustrated embodiment, the first base 23 takes the form of a single stringer, and in other embodiments, the first base 23 may take other forms, such as a multi-stringer form.
With continued reference to fig. 6, the first support frame 20 further comprises a support 25 extending in the longitudinal direction Y, the support 25 being arranged above the lifting mechanism 22, the axle support member 23 being arranged on the support 25. In the embodiment shown, two axle support members 23 are symmetrically arranged above the support 25 for supporting two axles of the active wheel set 1, for example as mentioned above, respectively. It should be appreciated that in other embodiments, a different number of axle support members 23 may be provided above the support 25, and the number of axle support members 23 may be determined based on the number of wheels of the wheel set to be supported. The axle support member 23 may be configured to include an arcuate support surface to match the shape of the axle to facilitate better supporting the axle and prevent slippage. The axle support member 23 may be provided with rotatable rollers 26 for slidably supporting the axle so as to allow the axle of the wheel to rotate. In the embodiment shown, two rollers 26 are provided per axle support member 23, and in other embodiments a greater or lesser number of rollers 26 may be provided.
With continued reference to fig. 6, in the illustrated embodiment, the lift mechanism 22 includes an articulating quadrilateral lift 221, an adjustment screw 222, and an operating handle 223. The articulated quadrilateral elevating frame 221 includes an upper movable joint 224, a lower movable joint and two middle movable joints 225 therebetween, the upper movable joint 224 is movably connected with the supporting member 25, the lower movable joint is movably connected with the first base 21, the adjusting screw 222 passes through the two middle movable joints 225 at the same time, and the operating handle 223 is connected with the adjusting screw 222. When the operating handle 223 is rotated in the first direction, the adjusting screw 222 rotates to drive the two middle movable joints 225 to approach each other, push the upper movable joint 224 to move upwards, and drive the supporting piece 25 and the wheel axle supporting member 23 to move upwards, so that the height is raised; when the operation handle 224 is rotated in a second direction opposite to the first direction, the adjustment screw 222 rotates accordingly, driving the two middle movable joints 225 away from each other, driving the upper movable joint 224 to move downward, driving the support 25 and the wheel shaft support member 23 to move downward, thereby lowering the height. In other embodiments, other types of lifting mechanisms may be used.
With continued reference to fig. 6, the first base 21 is provided with a first engaging structure 27 for engaging with the first link 41 and the second link 42, the first engaging structure 27 includes two engaging grooves (one of which is open toward the left side and one of which is open toward the right side in the drawing) open toward each other in the longitudinal direction Y, and the first link 41 and the second link 42 can be engaged into the corresponding engaging grooves. In the illustrated embodiment, the clamping groove of the first clamping structure 27 comprises a horizontal segment 271 extending in the longitudinal direction Y and a vertical segment 272 extending in the vertical direction. The first and second links 41, 42 may enter the horizontal segment 271 via an opening and then snap into the vertical segment 272. The vertically extending flange 273 serves to prevent the first and second links 41 and 43 from exiting the catch.
Fig. 7 is an isolated schematic view of the second support 30. In the embodiment shown, two sets of wheels 32, one for each set, are provided below the second base 31, each set being secured below the second base 31 by a wheel carrier.

With continued reference to fig. 7, in the illustrated embodiment, the second base 31 includes a middle recess 33, the middle recess 32 having a height lower than the heights of the side portions. The intermediate recessed portion 33 is provided with a second engagement structure 34 for engaging with the first link 41 and the second link 42. The second engaging structure 34 includes two engaging grooves (one of which is open toward the left and one of which is open toward the right in the drawing) open toward each other in the longitudinal direction Y, and one ends of the first link 41 and the second link 42 can be engaged into the corresponding engaging grooves, respectively. In the illustrated embodiment, the clamping groove of the second clamping structure 34 is a longitudinally extending linear clamping groove, i.e. comprises only a longitudinally extending horizontal section, and not a vertically extending vertical section.
Fig. 8 is an isolated schematic view of the linkage 40. In addition to the first and second links 41, 42, in the illustrated embodiment, the linkage mechanism 40 further includes a locking structure 43 for locking the first and second links 41, 42 together.
It should be appreciated that while in the illustrated embodiment the clamping grooves of the first clamping structure 27 comprise a horizontal section extending in the longitudinal direction Y and a vertical section extending in the vertical direction, the clamping grooves of the second clamping structure 34 comprise only a horizontal section extending in the longitudinal direction, in other embodiments the clamping grooves of the first and second clamping structures 27, 34 may each be arranged to comprise a horizontal section extending in the longitudinal direction Y and a vertical section extending in the vertical direction, or may each be arranged to comprise only a horizontal section extending in the longitudinal direction. It should be appreciated that where the detents of the first and second snap structures 27, 34 are each provided to include only longitudinally extending horizontal segments, a locking structure 43 must be provided for locking the first and second links 41, 42 together to ensure that the first and second links are not separated from the first and second support brackets. It should be understood that, in the case where the locking groove of at least one of the first and second locking structures 27 and 34 is provided to include a horizontal section extending in the longitudinal direction Y and a vertical section extending in the vertical direction, the locking structure 43 for locking the first and second links 41 and 42 together is not necessarily provided, and may be selectively added as needed in order to enhance the stability of the connection of the first and second links to the first and second support frames.
According to a second aspect of the present invention, there is provided a method of using the wheel anti-toppling device 10, comprising the steps of: placing the first support frame 20 on the wheel axle side of the wheel to be supported, adjusting the lifting mechanism 22 until the wheel axle supporting member 23 contacts and lifts the wheel axle of the wheel to be supported; placing the second support frame 30 on the other side of the wheel to be supported; the first support bracket 20 and the second support bracket 30 are connected together by a link mechanism 40. At this time, the assembly and support of the wheel anti-toppling device 10 are completed, and then the wheel conveyance can be started.
Wherein connecting the first support frame 20 and the second support frame 30 together with the link mechanism 40 includes: the first link 41 is engaged with the first engaging structure 27 and the second engaging structure 34, respectively, and then the second link 42 is engaged with the first engaging structure 27 and the second engaging structure 34, respectively, and then the first link 41 and the second link 42 are locked together by the locking mechanism 43.
In one specific example, the wheel anti-toppling device 10 described above may be utilized to eliminate the mechanical imbalance of the active wheel set of the bridge crane, allowing the active wheel set to move steadily. Based on the foregoing description, the driving wheel set eccentricity is mainly composed of the weight of the coupling and the wheel shaft. The following drawing is checked and calculated to know that: the weight of the coupler is 36Kg; the eccentric part of the wheel axle weighs about 42kg; the total eccentric weight is 78Kg. The wheel anti-toppling device 10 can meet the use requirement by designing the wheel load to be more than 156kg (a group of balancing frames have 2 driving wheels). Before use, the anti-toppling device 10 can be used for supporting and conveying the wheels of the driving wheel set only through stress checking according to the structure and stress condition of the anti-toppling device 10. The stress checking comprises checking the shear stress of the first base of the first supporting frame, wherein the shear stress is required to meet the design requirement. The stress checking comprises the step of checking the normal stress of the lifting mechanism pull rod (namely the adjusting screw), wherein the normal stress is required to meet the design requirement.
An example of a verification process is given below:
checking the shear stress of the first support frame base:
τ＝Q/A＝780N/0.0816m 2 ＝9559pa<tau number=113 MP (meet design requirements)
Checking the positive stress of the lifting mechanism pull rod: ( The pull rod is subjected to maximum pulling force F=1560N in the working state; the pull rod is phi 16 round steel )
Positive stress σ=p/a=1560n/200.96 mm 2 ＝77627pa<335MP。
In this example, the shear and normal stresses are required to meet design requirements, so the anti-toppling device 10 may be used to support and transport the wheels of an active wheel set.
The use of anti-toppling device 10 to support and transport the wheels of an active wheel set changes the traditional "pouring" mode to the "out" mode, namely: the method is characterized in that the mode of hoisting, transporting, dragging and moving out is not adopted, the supporting point of the disassembled wheel set is changed from one line to a surface formed by a plurality of lines, the stability problem of the driving wheel set in a free state and in a moving process is solved, the driving wheel set is guided in an outward direction of a track, 2 persons cooperate with each other, the wheel set is guided out in a pushing mode, the operation modes of dragging, pulling and dragging in the past are optimized and improved into the mode of only needing the easy cooperation of the automobile crane, the anti-toppling device 10 and the personnel, the guiding and moving out of the wheels can be completed, the easy, convenient and quick replacement process is realized, the wheel replacement efficiency is improved by 25%, and the safe and essential leap is realized.
It should be noted that, each component or step in each embodiment may be intersected, replaced, added, and deleted, and therefore, the combination formed by these reasonable permutation and combination transformations shall also belong to the protection scope of the present invention, and shall not limit the protection scope of the present invention to the embodiments.
