Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile power assembly dismounting, more particularly to a portable dismounting power assembly supporting device. BACKGROUND

[0002] The power assembly of an automobile, especially the engine, needs to be lifted off the automobile using a lifting machine during repair. Specifically, when the power assembly needs to be repaired due to a fault, the entire vehicle is first lifted, and then the power assembly is lifted off and repaired. During the process of lifting the power assembly off the vehicle body, the lifting machine is mostly a kink lifting system. After the tray for supporting the power assembly is aligned with the power assembly, the kink lifting system is used to control the power assembly to descend. Before the power assembly descends, four supports need to be manually installed in the positioning holes at the corresponding positions on the power assembly, and then the power assembly is driven to descend. During the descent of the power assembly, the operator needs to manually intervene to find the connection position and then fix the supports of the power assembly on the transfer tray legs.

[0003] During the above process of lifting the power assembly off, if the alignment by manual intervention is inaccurate, the external parts of the power assembly are likely to be damaged, and safety hazards may also occur. In addition, too much manual intervention will also result in low work efficiency. SUMMARY

[0004] The utility model aims at overcoming the problem that during the process of lifting the power assembly off, manual intervention to connect the power assembly supports and the transfer tray legs not only has the risk of misalignment, but also has low work efficiency. The utility model provides a portable dismounting power assembly supporting device. The supporting device can be fixed on the power assembly before the power assembly descends. When the power assembly descends onto the tray, the power assembly is fixed on the tray by the supporting device, which is simple and convenient to operate and has high efficiency.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

[0006] The utility model provides a portable dismounting power assembly supporting device, which comprises a frame base, a light shaft and an adjusting foot cup.

[0007] The frame base comprises two long rods and two short rods. The two long rods and the two short rods are sequentially connected to form a rectangular frame base.

[0008] The optical axis includes a first optical axis, a second optical axis, a third optical axis, and a fourth optical axis, which can be respectively inserted into four positioning holes at the bottom of the powertrain. The first and second optical axes are respectively mounted on two of the long rods, and the third and fourth optical axes are both mounted on the same short rod. The adjusting foot cup is mounted on another short rod. The supporting part at the top of the adjusting foot cup is rotatable.

[0009] The operator holds the support device and aligns the optical axis on the frame base with the positioning hole on the powertrain being lifted, ensuring the adjusting feet are in contact with the bottom surface of the powertrain. The operator then secures the frame base to the powertrain using connecting ropes and other devices. The powertrain is then lowered using the KBK lifting system. Once the powertrain is on the pallet, it is placed on the pallet by the support device. When the support device is on the pallet, its four optical axes and the adjusting feet in contact with the powertrain provide support, and the plane of the frame base aligns with the top surface of the pallet, ensuring the support device is stably placed on the pallet.

[0010] The supporting device in this solution allows the operator to align the powertrain with the positioning holes before it descends. During descent, the powertrain is placed on the pallet using the supporting device. Using this device eliminates the need to connect the pallet and powertrain during descent, preventing misalignment issues. Furthermore, the device is lightweight, easy to carry and operate, and highly efficient.

[0011] Furthermore, both the long and short rods are hollow aluminum rods. The hollow nature of both the long and short rods allows for a reduction in the weight of the frame base while maintaining its strength. Both the long and short rods are made of 40 series aluminum alloy, and the thickness of the hollow rod sheet can be 2mm-4mm.

[0012] Furthermore, it also includes an optical axis seat, with the bottom of each optical axis threadedly connected to one of the optical axis seats. Both the long rod and the short rod are provided with sliding grooves, within which the optical axis seat can slide. The optical axis is mounted on the frame base via the optical axis seat. The sliding optical axis seat allows adjustment of the optical axis's position on the frame base, enabling the optical axis in the support device to align with positioning holes at different locations on more powertrain models, thus expanding the applicability of the support device. The threaded connection between the optical axis and the optical axis seat allows for disassembly of the optical axis from the frame base. When not in use, the optical axis can be removed from the frame base, facilitating the storage of the support device.

[0013] Furthermore, it also includes a first fixing bolt and a first sliding nut. In a direction perpendicular to the axis of the slide groove, the cross-section of the slide groove is convex. The optical axis seat has a positioning hole through which the first fixing bolt can pass. The first sliding nut is located inside the slide groove and slidably connected to it. The first fixing bolt passes through the positioning hole, extends into the interior of the slide groove, and is threadedly connected to the first sliding nut. The convex cross-section of the slide groove, with the first sliding nut located at the wider bottom of the convex slide groove, and the first fixing bolt passing through the narrower top of the convex slide groove and threadedly connected to the first sliding nut, prevents the first sliding nut from falling out from the top of the slide groove. After position adjustment is completed, the first fixing bolt and the first sliding nut are tightened, clamping the slide groove with the first sliding nut and the optical axis seat, thereby fixing the optical axis seat to the frame base, completing the fixation of the optical axis on the frame base.

[0014] Furthermore, it also includes an adjustable foot cup holder, which can slide on the groove of the short rod, and the bottom of the adjustable foot cup is threadedly connected to the adjustable foot cup holder. The adjustable foot cup holder allows the adjustable foot cup to slide on the frame base, facilitating the adjustment of the position of the foot cup holder on the frame base, and enabling the adjustable foot cup to support more types of powertrain devices.

[0015] Furthermore, it also includes a second fixing bolt and a second sliding nut. The second sliding nut is located within the slide groove. The adjusting foot cup seat has a slot through which the second fixing bolt passes. The second fixing bolt passes through the slide groove and is bolted to the second sliding nut. The second sliding nut is located at the wider bottom of the convex slide groove, and the second fixing bolt passes through the narrower top of the convex slide groove and is threaded to the second sliding nut, which prevents the second sliding nut from falling out from the top of the slide groove. After the position adjustment of the adjusting foot cup is completed, the second fixing bolt and the second sliding nut are tightened to fix the adjusting foot cup seat to the frame base, thereby completing the fixation of the adjusting foot cup on the frame base.

[0016] Furthermore, it also includes two hanging loops through which ropes can pass, each fixedly installed in the middle of one of the two long rods. The hanging loops facilitate securing the support device to the engine with ropes. Because the hanging loops are located in the middle of the long rods, securing the device to the powertrain with a traction rope reduces the likelihood of the device's center of gravity shifting.

[0017] Furthermore, both ends of the long rod are provided with reinforcing ribs, which connect the long rod and the short rod. The addition of reinforcing ribs can further increase the rigidity of the frame base and prevent deformation of the frame base.

[0018] Furthermore, along the axial direction of the first optical axis, the total length of the first optical axis and the frame base is 260mm-270mm, the total length of the second optical axis and the frame base is 220mm-230mm, the length of the third optical axis and the frame base is 130mm-140mm, and the length of the fourth optical axis and the frame base is 110mm-120mm. Since the depths of the four positioning holes on the powertrain are different, the lengths of the four optical axes are not consistent. Preferably, the total length of the first optical axis and the frame base is 265mm, the total length of the second optical axis and the frame base is 228mm, the length of the third optical axis and the frame base is 138mm, and the length of the fourth optical axis and the frame base is 112mm.

[0019] Furthermore, the top of the adjustable feet is provided with an anti-slip pad, and the anti-slip pad has anti-slip texture. The anti-slip pad and anti-slip texture prevent the adjustable feet from rotating again and falling off after they are in contact with the powertrain.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The supporting device of this invention allows the operator to align the powertrain with the positioning holes before it descends. During the descent, the powertrain is placed on a tray using the supporting device. Using this device eliminates the need to connect the tray and the powertrain during descent, avoiding misalignment issues. Furthermore, the device is lightweight, easy to carry and operate, and highly efficient.

[0022] In this utility model, both the optical axis and the adjusting feet in the support device can slide on the frame base, allowing the position of the optical axis and the adjusting feet on the frame base to be adjusted. This enables the optical axis in the support device to be aligned with the positioning holes on more powertrain models, and the adjusting feet to support more powertrain models, thus expanding the applicability of the support device.

[0030] This embodiment is a first embodiment of a portable powertrain mounting and disassembly support device, such as... Figure 1 and Figure 2 As shown, the device includes a frame base, an optical axis, and an adjusting foot cup 1. Both the optical axis and the adjusting foot cup 1 are mounted on the frame base. The frame base includes two long rods 2 and two short rods 3, which are sequentially connected to form a rectangular frame base. The optical axis includes a first optical axis 4, a second optical axis 5, a third optical axis 6, and a fourth optical axis 7, which can be inserted into four positioning holes at the bottom of the powertrain. The first optical axis 4 and the second optical axis 5 are respectively mounted on the two long rods 2, while the third optical axis 6 and the fourth optical axis 7 are both mounted on the same short rod 3. The adjusting foot cup 1 is mounted on another short rod 3. The supporting portion at the top of the adjusting foot cup 1 is rotatable.

[0031] The working principle of this embodiment is as follows:

[0032] The operator holds the support device and aligns the optical axis on the frame base with the positioning hole on the powertrain being lifted, ensuring that the adjusting feet 1 are in contact with the bottom surface of the powertrain. The operator then secures the frame base to the powertrain using connecting ropes and other devices. The powertrain is then lowered using the KBK lifting system. Once the powertrain is on the pallet, it is placed on the pallet by the support device. When the support device is on the pallet, its four optical axes and the adjusting feet 1, which are in contact with the powertrain, provide support. At this point, the plane of the frame base aligns with the top surface of the pallet, ensuring the support device is stably placed on the pallet.

[0033] The beneficial effects of this embodiment are as follows:

[0034] In this embodiment, the supporting device allows the operator to align the powertrain with the positioning holes before it descends. During descent, the powertrain is placed on the tray using the supporting device. This design eliminates the need to connect the tray and powertrain during descent, preventing misalignment. Furthermore, the device is lightweight, easy to carry and operate, and highly efficient.

[0035] Example 2

[0036] This embodiment is a second embodiment of a portable powertrain mounting and disassembly support device, such as... Figures 1-3 As shown, this embodiment further defines the structure of the optical axis and the frame base based on embodiment one.

[0037] Specifically, both long rod 2 and short rod 3 are hollow aluminum rods. Both long rod 2 and short rod 3 are made of 40 series aluminum alloy, and the thickness of the hollow rod plate can be 2mm-4mm. Both long rod 2 and short rod 3 are provided with sliding grooves, and the cross-section of the sliding groove is convex in the direction perpendicular to the axis of the sliding groove.

[0038] Specifically, it also includes an optical axis seat 8, with the bottom of each optical axis threadedly connected to an optical axis seat 8, which can slide within a groove. It also includes a first fixing bolt 12 and a first sliding nut 13. The optical axis seat 8 has a positioning hole through which the first fixing bolt 12 passes. The first sliding nut 13 is located within the wider portion of the groove and is slidably connected to the groove. The first fixing bolt 12 passes through the positioning hole, extends into the narrower portion of the groove, and is threadedly connected to the first sliding nut 13.

[0039] Specifically, it also includes an adjusting foot cup seat 9, which slides on the groove of the short rod 3, and the bottom of the adjusting foot cup 1 is threadedly connected to the adjusting foot cup seat 9. It also includes a second fixing bolt and a second sliding nut. The second sliding nut is located within the groove, and the adjusting foot cup seat 9 has a slot through which the second fixing bolt passes. The second fixing bolt passes through the groove and is bolted to the second sliding nut. The second sliding nut is located at the wider bottom of the convex groove, and the second fixing bolt passes through the narrower top of the convex groove and is threaded to the second sliding nut. The structure of the second fixing bolt is the same as that of the first fixing bolt 12, and the structure of the second sliding nut is the same as that of the first sliding nut 13.

[0040] The beneficial effects of this embodiment are as follows:

[0041] Both long rod 2 and short rod 3 are hollow rods, which further reduces the mass of the frame base while maintaining its strength. The optical axis is mounted on the frame base via an optical axis seat 8. The optical axis seat 8 is slidable, allowing adjustment of the optical axis's position on the frame base. This enables the optical axis in the support device to align with the positioning holes on more powertrain models, thus expanding the applicability of the support device. Adjusting the foot cup seat 9 allows the foot cup 1 to slide on the frame base, facilitating position adjustment and enabling the foot cup 1 to support more powertrain models.

[0042] Example 3

[0043] This embodiment is a third embodiment of a portable powertrain assembly support device. This embodiment is based on embodiments one and two, such as... Figure 1 and Figure 2 As shown, the structure of the device is further defined.

[0044] Specifically, it also includes two hanging rings 10 through which ropes can pass, and the two hanging rings 10 are fixedly installed in the middle of the two long rods 2. Each end of the long rod 2 is provided with a reinforcing rib 11, which connects the long rod 2 and the short rod 3.

[0045] Specifically, along the axial direction of the first optical axis 4, the total length of the first optical axis 4 and the frame base is 265mm, the total length of the second optical axis 5 and the frame base is 228mm, the length of the third optical axis 6 and the frame base is 138mm, and the length of the fourth optical axis 7 and the frame base is 112mm.

[0046] Specifically, the top of the adjustable foot cup 1 is equipped with an anti-slip pad, and the anti-slip pad has anti-slip texture.

[0047] The beneficial effects of this embodiment are as follows:

[0048] The addition of the hanging ring 10 makes it easier to secure the support device to the engine with a rope. The hanging ring 10 is located in the middle of the long rod 2, preventing the overall center of gravity from shifting when the device is secured to the powertrain with a traction rope. The anti-slip pads and anti-slip textures prevent the adjusting feet 1 from rotating and falling off after being in contact with the powertrain.

[0049] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
