It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0037] like Figure 1-Figure 7As shown, the embodiment of the present application proposes a movable lifting tool, including a mobile base 1; the mobile base 1 includes a first moving part 11 and a second moving part 12, and the first moving part 11 and the second moving part 12 are arranged at an interval; there are two lifting components 2, one of which is installed on the first moving part 11, and the other lifting component 2 is installed on the second moving part 12 (the bottom of the lifting component 2 is connected to a connecting plate 22, and the connecting plate 22 is fixed to the moving part by bolts). The lifting component 2 in this solution adopts a jack in the prior art (including a jacking frame, a screw, and a motor connected to the screw, and the motor drives the screw to rotate to realize the lifting of the controller). Since it is a prior art, it will not be described in detail; it also includes a lifting component 3, and the lifting component 3 is connected to The number of lifting components 2 is matched (two are provided), and the lifting component 3 is detachably connected to the upper end of the lifting component 2. The two lifting components 3 respectively support the two ends of the object to be transferred, thereby realizing the installation of the object to be transferred on the first movable member 11 and the second movable member 12; when transferring, the staff can control the movement trajectory of the first movable member 11 and the second movable member 12 respectively to realize more flexible adjustment of the overall movement path of the object to be transferred. The first movable member 11 and the second movable member 12 are separately provided and their movement trajectories can be controlled individually, so that the first movable member 11 and the second movable member 12 cooperate with each other, so that the adjustment of the movement trajectory of the object to be transferred has a higher degree of freedom and flexibility (better adapted to the relatively narrow test space of the test bench). At the same time, due to the detachable connection between the lifting component 3 and the lifting component 2, the matching lifting component 3 can be selected according to the different objects to be transferred, thereby expanding the functionality of the tooling.

[0038] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the lifting component 3 includes a connecting portion 31 and a lifting portion 32 connected to the upper end of the connecting portion 31. The connecting portion 31 is detachably connected to the upper end of the lifting component 2. The two lifting portions 32 correspondingly lift the two ends of the object to be transferred.

[0039] In some embodiments of the present application, Figure 3 As shown, the upper end of the lifting assembly 2 has a mounting portion 21 for mounting the connecting portion 31 , and the connecting portion 31 is threadedly connected to the mounting portion 21 .

[0040] In some embodiments of the present application, Figure 1As shown, the movable lifting tooling also includes an auxiliary transport part 4, which includes a square shaft 41. The part to be transported is a test rim 5, which is usually used in the research and development, testing and verification stages to evaluate the performance and reliability of new designs, new materials or new technologies. The test rim 5 will be customized according to specific test needs. The inner ring of the test rim 5 is square. When it is necessary to perform corresponding tests on it, the test rim 5 needs to be transported to the test bench to carry out various tests; before the test rim 5 is tested, the auxiliary transport part 4 needs to be assembled with the test rim 5 (to facilitate its transportation and test operations in subsequent tests); specifically: pass the square shaft 41 through the inner ring of the test rim 5 (such as Figure 1 As shown), the test rim 5 is sleeved on the square shaft 41 (the size of the square shaft 41 matches the inner ring of the test rim 5), and then the two lifting parts 32 respectively lift the two ends of the square shaft 41. The staff transfers the test rim 5 to the test bench by controlling the first movable member 11 and the second movable member 12; the cooperation between the square shaft 41 and the clamping groove 3211, on the one hand, helps to control the installation angle of the test rim 5 on the test bench, and on the other hand, has better movement stability, which is safer during transportation.

[0041] In some embodiments of the present application, the connecting portion 31 is a connecting rod, such as Figure 3 As shown, a first threaded portion 311 is provided at the bottom of the connecting rod, and the mounting portion 21 has a threaded hole 211 that cooperates with the first threaded portion 311; the first threaded portion 311 is screwed into the threaded hole 211 provided on the mounting portion 21, thereby realizing the installation of the connecting portion 31 on the lifting assembly 2; when different types of objects need to be transported, a lifting portion 32 that matches the contact surface of the transported object is selected to realize the lifting of the object to be transported.

[0042] In some embodiments of the present application, Figure 2 、 Figure 3 、 Figure 4 As shown, the lifting portion 32 includes a lifting frame 321 connected to the upper end of the connecting portion 31, and a snap-in groove 3211 is provided along the width direction of the lifting frame 321 (the bottom of the snap-in groove 3211 is set to be a plane, so that there is a relatively stable contact surface between it and the square shaft 41), and the snap-in groove 3211 is used to snap-in the square shaft 41; the size of the snap-in groove 3211 is slightly larger than the side length of the square shaft 41, so that the square shaft 41 can be placed in the snap-in groove 3211.

[0043] In some embodiments of the present application, the connecting rod can be set to have multiple length specifications to adapt to test rims 5 of different sizes. For example, when a large-sized test rim 5 is transported or installed, disassembled, or other operations are performed on it, a longer connecting rod can be used for lifting. Because the large-sized test rim 5 requires a higher lifting height (compared to the small-sized test rim 5) when it is transported or other operations are performed on it, in order to avoid the lifting component 2 (jack) from being over-extended and causing instability, a connecting part 31 with a longer specification can be selected. When the lifting component 2 is lifted to the same height, the use of a connecting part 31 with a larger length specification can lift the part to be transported to a higher height.

[0044] In some embodiments of the present application, during a series of tests on the test rim 5, some projects also involve adjusting the rolling angle of the test rim 5, that is, the test rim 5 can be rotated according to the test needs (in this case, the lifting frame 321 in the above embodiment can no longer achieve this effect). This embodiment provides a lifting portion 32 for achieving the above effect; specifically, it includes a rolling frame 322 connected to the upper end of the connecting portion 31, the rolling frame 322 has a first rod 3221 and a second rod 3222, the first rod 3221 and the second rod 3222 are symmetrically connected to both sides of the upper end of the connecting portion 31; the first rod 3221 and the second rod 3222 are both inclined from bottom to top in a direction away from the connecting portion 31, so that the interval between the first rod 3221 and the second rod 3222 constitutes a V-shaped groove 3223 for lifting the part to be transported (such as Figure 6 、 Figure 7 As shown in FIG3 ); a plurality of first rolling balls 3224 are provided on the side of the first rod 3221 facing the V-shaped groove 3223. The first rolling balls 3224 extend axially along the width direction of the first rod 3221 and are spaced apart along the length direction of the first rod 3221. The first rolling balls 3224 are rotatably mounted on the first rod 3221 (mounted on the first rod 3221 via a bearing), and the first rolling balls 3224 are at least partially located in the V-shaped groove 3223; a plurality of second rolling balls 3225 are provided on the side of the second rod 3222 facing the V-shaped groove 3223. The second rolling balls 3225 extend axially along the width direction of the second rod 3222 and are spaced apart along the length direction of the second rod 3222. The second rolling balls 3225 are rotatably mounted on the second rod 3222 (mounted on the second rod 3222 via a bearing), and the second rolling balls 3225 are at least partially located in the V-shaped groove 3223.

[0045] During the specific implementation of this embodiment, the connecting portion 31 on which the rolling frame 322 is installed is first assembled on the mounting portion 21, and the two ends of the square shaft 41 are respectively placed in the corresponding V-grooves 3223. The outer contour of the square shaft 41 contacts the portion of the first rolling ball 3224 protruding from the first rod 3221 and contacts the portion of the second rolling ball 3225 protruding from the second rod 3222. By rotating the square shaft 41, the square shaft 41 can be rotated in the V-groove 3223 under the cooperation of the multiple first rolling balls 3224 and the second rolling balls 3225, thereby driving the test rim 5 to adjust the rolling angle.

[0046] In some embodiments of the present application, in order to more conveniently adjust the rolling angle of the test rim 5, this embodiment provides an auxiliary transfer member 4, including a sleeve 42, wherein two sleeves 42 are provided, and the two sleeves 42 are correspondingly sleeved (welded or bolted) on the square shaft 41 located on both sides of the member to be transferred (the sleeve connection positions of the two sleeves 42 and the square shaft 41 and the clamping position of the clamping groove 3211 and the square shaft 41 are staggered); the sleeve 42 is accommodated in the V-shaped groove 3223 so that the outer periphery of the sleeve 42 abuts against the surfaces of the first rolling ball 3224 and the second rolling ball 3225, respectively, as shown in FIG. Figure 7 As shown, when the angle of the test rim 5 needs to be adjusted, the square shaft 41 is still rotated. Since the square shaft 41 is in contact with the surfaces of the first rolling ball 3224 and the second rolling ball 3225 through the sleeve 42 (round), the adjustment of the rolling angle of the test rim 5 is easier and faster, and it helps the staff to accurately control the adjustment of the angle of the test rim 5, thereby improving the test efficiency.

[0047] In some embodiments of the present application, Figure 1As shown, the first movable member 11 includes a first movable plate 111, and the second movable member 12 includes a second movable plate 121 (a steel plate); the bottom of the first movable plate 111 and the second movable plate 121 are both arrayed with a plurality of bull's eye universal balls 14. The bull's eye universal balls 14 can adjust their positions in any horizontal direction (the bull's eye universal ball 14 is a mechanical component, also known as a universal ball, universal conveyor ball, steel ball wheel, etc. Its structure is usually a stamped part with a steel ball installed in the middle; it can easily turn, rotate, and push a single object, allowing objects to be easily turned in the horizontal direction, and realizing multi-directional motion transmission), further improving the mobility of the tooling, allowing the operator to adjust and control the position of the test rim 5 more flexibly and accurately. At the same time, the use of bull's eye universal balls 14 installed at the bottom of the first movable plate 111 and the second movable plate 121 can reduce the height of the base to adapt to the installation and use scenarios of small rims. Handrails 13 are respectively provided on the first movable plate 111 and the second movable plate 121. The first movable member 11 and the second movable member 12 in this solution only need one person to operate to realize the transfer of objects. The staff stands in the middle position of the first movable member 11 and the second movable member 12, and holds the two handrails 13 with both hands, so as to realize the adjustment of various positions and roll angles of the test rim 5 on the test bench with a relatively narrow working surface; the lifting work in this solution adopts the existing jack installed on the movable base 1 and realizes the transfer of objects and the adjustment of the roll angle through the cooperation of the connecting part 31 and the lifting part 32. They are all assembled from components with relatively simple structures, which effectively reduces the cost of processing and assembling the lifting tooling.

[0048] The working process of the present invention is as follows: first, the test rim 5 is sleeved on the square shaft 41, and the sleeves 42 are respectively sleeved on the square shafts 41 on both sides of the test rim 5; according to different test requirements, the lifting frame 321 with a snap-fit ​​groove 3211 (which snaps into place with the square shaft 41) or the rolling frame 322 with a V-shaped groove 3223 (which fits with the sleeve 42) is selected accordingly to complete various test operations.

[0049] In summary, the embodiment of the present invention provides a movable lifting tooling, and this scheme arranges a first moving part 11 and a second moving part 12 and arranges a lifting component 2 and a lifting component 3 on the first moving part 11 and the second moving part 12 respectively, and lifts the two ends of the part to be transferred (test rim 5) respectively through the lifting component 3 to realize the transfer and position adjustment of the part to be transferred; since the first moving part 11 and the second moving part 12 are provided, the moving trajectories of the first moving part 11 and the second moving part 12 can be controlled separately and then the overall moving path of the part to be transferred can be flexibly adjusted, so that the transfer control of the part to be transferred has higher flexibility and freedom, and can be better adapted to the test bench with a smaller working surface, so that the staff can adjust the position of the part to be transferred conveniently, and provide convenience for the implementation of the test work.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
