Description

Technical Field

[0001] The utility model belongs to the technical field of automobile exhaust assembly installation, in particular to an automobile exhaust post-processing assembly hoisting device. Background Art

[0002] The center of gravity of the automobile exhaust after-treatment assembly is difficult to determine due to its complex structure. During the lifting process, not only will the two ends of the slings tie the automobile exhaust after-treatment assembly into a knot for fixing during lifting, but also the center of gravity cannot be accurately found due to the random fixing, so that the automobile exhaust after-treatment assembly cannot maintain balance during lifting, and the hole installation angle is misaligned. Therefore, during the lifting process, it is necessary to repeatedly disassemble the slings and adjust the lifting position to find the center of gravity of the automobile exhaust after-treatment assembly so that the hole installation angle is aligned. Therefore, lifting devices that can facilitate the installation of automobile exhaust assemblies have gradually appeared.

[0003] For example, patent application number CN202223422100.2 discloses a lifting device for an automobile exhaust after-treatment assembly, comprising an exhaust treatment assembly main body, a support plate being detachably mounted on the surface of the exhaust treatment assembly main body, a first spring being fixedly mounted on one side surface of the support plate, a telescopic rod and an adjusting plate being fixedly mounted between the two support plates, a cap hole being opened on the surface of the adjusting plate, the cap hole and the cap head being matched with each other, and the clamp being rotated through a hinge through the mutual cooperation between the clamp and the support plate, so that the exhaust treatment assembly main body is fixed in the clamp, and the distance between the two support plates can be adjusted according to the exhaust treatment assembly main body of different lengths through the mutual cooperation between the telescopic rod and the adjusting plate, and the exhaust treatment assembly main body can be fixed from the side through the mutual cooperation between the first spring and the baffle plate to prevent the exhaust treatment assembly main body from slipping, so that the exhaust treatment assembly main body can be effectively and conveniently lifted.

[0004] In the prior art, the support plate, the clamping plate and the telescopic plate are arranged so that the device can effectively complete the lifting, handling and installation of the automobile exhaust assembly. However, there are still certain shortcomings during the use of the whole: although the existing lifting device can form a clamp at both ends of the exhaust assembly to complete the handling, the overall lifting is in the form of an inverted clamp, and the bottom of the exhaust assembly lacks the necessary support. The clamping claws at both ends are under great pressure, the wear is relatively serious, and it is easy to be damaged, and the safety of use cannot be guaranteed. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a lifting device for an automobile exhaust after-treatment assembly. The utility model uses a semi-arc seat and a semi-arc plate as well as an elastic inclined plate and an elastic strip so that the exhaust assembly is clamped and fixed at both ends in a wrapped manner, and an elastic support can be formed at the bottom, so that the clamping and fixing effect is improved and the vibration generated during the mobile installation can also be absorbed, thereby effectively improving the stability during installation.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting device for automobile exhaust after-treatment assembly, including a base, a slide plate, the base is provided with slide plates that can slide outward on both sides, the outer end faces of the two slide plates are provided with semi-arc seats, the end faces of the semi-arc seats are provided with detachable semi-arc plates, a clamping circular cavity is formed between the semi-arc seats and the semi-arc plates, two elastic inclined plates inclined outward are provided on the end faces of the base, and a plurality of elastic strips are connected and provided between the two elastic inclined plates. The provision of a plurality of elastic strips enables the bottom of the exhaust assembly to be elastically supported during lifting, which not only avoids the arbitrary shaking of the exhaust assembly, but also absorbs certain vibrations and improves stability.

[0007] Preferably, a plurality of hook plates are provided on both side end surfaces of the base, and a plurality of conical grooves are provided on the inner end surfaces of the hook plates. The provision of the conical grooves increases the contact friction between the traction rope or the hook and the hook plate, which can effectively prevent the traction rope from slipping and deflecting.

[0008] Preferably, the semi-arc seat and the semi-arc plate are both provided with a plurality of pressing blocks on their inner circumferential surfaces, and each of the pressing blocks is provided with a plurality of anti-skid grooves on its arc surface. The provision of the anti-skid grooves and the pressing blocks effectively improves the clamping stability of the semi-arc seat and the semi-arc plate on the exhaust assembly.

[0009] Preferably, a plurality of rough surface sleeves are arranged outside each of the elastic strips. The provision of the rough surface sleeves can improve the contact friction and stability with the outside of the exhaust assembly.

[0010] Preferably, a plurality of second connection holes are arranged on the bottom end surface of the base, and a plurality of first connection holes are arranged on the end surface of the slide outside the second connection holes. The arrangement of the first connection holes and the second connection holes enables the slide to be fixed smoothly after being moved outward.

[0011] Preferably, the semi-arc seat and the semi-arc plate are connected and fixed by a mounting plate. The arrangement of the mounting plate enables the semi-arc plate and the semi-arc seat to be quickly assembled and disassembled.

[0012] Preferably, a plurality of convex strips are arranged on the end surface of the hook plate at both sides of the conical groove. The arrangement of the convex strips can improve the stability of the traction rope or the hook when it is hung on the hook plate.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0014] The utility model uses the arrangements of a semi-arc seat and a semi-arc plate as well as an elastic inclined plate and an elastic strip, so that the exhaust gas assembly can be clamped and fixed at both ends, and a semi-wrapped elastic support can be formed at the bottom, which can effectively prevent the exhaust gas assembly from slipping, thereby improving the clamping and fixing effect. At the same time, the vibration generated during mobile installation can also be absorbed, effectively improving the stability and safety during installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0022] Embodiment 1:

[0023] refer to Figure 1-6 A lifting device for an automobile exhaust aftertreatment assembly includes a base 10 and a slide plate 11. The base 10 is provided with slide plates 11 that can slide outward on both sides thereof. Semi-arc seats 15 are provided on the outer end surfaces of the two slide plates 11. A detachable semi-arc plate 16 is provided on the end surface of the semi-arc seats 15. A clamping circular cavity is formed between the semi-arc seats 15 and the semi-arc plate 16.

[0024] The base 10 is provided with slots inside to cooperate with the slides 11, so that the two slides 11 can slide inside the base 10. The cross-section of the slide 11 is I-shaped, and the overall strength is guaranteed to a certain extent. When the exhaust assembly needs to be hoisted, the staff can adjust the extended length of the two slides 11 according to the length of the exhaust assembly, thereby adjusting the distance between the two semi-arc seats 15. Then the staff can place the exhaust assembly on the inner circular surface of the two semi-arc seats 15.

[0025] Two outwardly inclined elastic inclined plates 12 are arranged on the end surface of the base 10, and a plurality of elastic strips 13 are connected and arranged between the two elastic inclined plates 12, and the elastic strips 13 are made of elastic material. When placed, the exhaust assembly will also abut against each other with the plurality of elastic strips 13 between the two elastic inclined plates 12, and the elastic strips 13 are made of elastic material. When subjected to pressure, the elastic strips 13 will bend and deform outside the exhaust assembly to form a semi-encapsulation, and a certain elastic supporting force will be generated during the deformation process. At this time, if the semi-arc plate 16 needs to be buckled on the top of the semi-arc seat 15, when the clamping of the exhaust assembly is completed, a secondary clamping pressure will be formed between the semi-arc plate 16 and the elastic strips 13, so that the stability of the exhaust assembly as a whole after being clamped is effectively improved.

[0026] In the above relationship, the base 10 and the slide plate 11 are both located below the exhaust assembly. Compared with the traditional arrangement in which the base plate is located above the exhaust, the protection effect on the exhaust is better and the situation in which the clamping jaws fall downward due to insufficient pressure can be avoided. When the elastic strips 13 form a semi-wrapped support, multiple elastic strips 13 with bending tension deformation can also prevent the exhaust assembly from shaking at will, and can also absorb the vibration generated when the device moves, so that the exhaust assembly can be installed smoothly. The two elastic inclined plates 12 are tilted outward and opened. On the one hand, it is convenient for the exhaust assembly to be placed smoothly on the multiple elastic strips 13. On the other hand, when the elastic strips 13 are over-stressed, they can also be appropriately tilted and deformed outward to ensure the supporting and fixing effect of the automobile assembly.

[0027] refer to Figure 1 A plurality of rough surface sleeves 14 are arranged outside each elastic strip 13 .

[0028] A plurality of rough surface sleeves 14 are sleeved on the outside of the elastic strip 13, and a plurality of anti-skid particles are arranged on the surface of each rough surface sleeve 14, so that the rough surface sleeve 14 can better fit on the outside of the exhaust assembly, form a good contact friction force with the exhaust assembly, and better avoid the shaking of the exhaust assembly.

[0029] refer to Figure 3 A plurality of pressing blocks 17 are arranged on the inner circumferential surfaces of the semi-arc seat 15 and the semi-arc plate 16 . The pressing blocks 17 are made of elastic material, and a plurality of anti-slip grooves 18 are arranged on the arc surface of each pressing block 17 .

[0030] The pressure block 17 is made of elastic material. When the semi-arc seat 15 and the semi-arc plate 16 clamp the exhaust assembly, multiple arc surfaces of the pressure blocks 17 can contact and clamp the exhaust assembly, which has a certain vibration absorption effect while avoiding damage to the outer surface of the exhaust assembly. Multiple anti-slip grooves 18 can increase the contact friction, thereby improving the clamping stability and making it safer during lifting and installation.

[0031] refer to Figure 3 The semi-arc seat 15 and the semi-arc plate 16 are connected and fixed by a mounting plate 22 .

[0032] The semi-arc seat 15 and the semi-arc plate 16 are both provided with mounting plates 22 on their adjacent end surfaces. The mounting plates 22 are provided with holes for connection on their end surfaces, and the staff can tighten them with bolts.

[0033] refer to Figure 6 A plurality of hook plates 19 are provided on both side end surfaces of the base 10 , and a plurality of tapered grooves 23 are provided on the inner end surfaces of the hook plates 19 .

[0034] The staff can hang the traction rope on multiple hook plates 19, so as to lift the base 10 and the automobile exhaust placed on the two semi-arc seats 15 to complete the installation process. The multiple conical grooves 23 on the inner end surface of the hook plate 19 can increase the contact friction with the traction rope, so that the traction rope will not swing at will when it is hung on the hook plate 19, thereby ensuring the safety of lifting.

[0035] refer to Figure 2 A plurality of second connection holes 21 are arranged on the bottom end surface of the base 10 , and a plurality of first connection holes 20 are arranged on the end surface of the slide plate 11 outside the second connection holes 21 .

[0036] When the slide plate 11 is pulled outward, the staff can connect the second connection hole 21 and the first connection hole 20 by bolts, so as to fix the slide plate 11 and the base 10 .

[0037] Embodiment 2:

[0038] On the basis of or different from the first embodiment, reference Figure 6 A plurality of convex strips 24 are arranged on the end surface of the hook plate 19 on both sides of the tapered groove 23 .

[0039] The provision of the convex strip 24 improves the surface roughness of the inner end surface of the hook plate 19, so that when the traction rope is embedded in the tapered groove 23, the overall stability is effectively improved, and the shaking of the traction rope can be effectively avoided.
