Description

Technical Field

[0001] The present application belongs to the technical field of hoisting equipment, and specifically relates to a vehicle body electrophoresis hoisting equipment. Background Art

[0002] In the automobile production process, electrophoretic coating is an important production stage. The car body needs to be immersed in water-based paint containing special resins and pigments. The area where these water-based paints are loaded is called the electrophoretic pool. Under the action of the electric field, these particles will migrate and deposit on the surface of the car body to form a dense paint film, which is called the electrophoretic layer. When painting the electrophoretic layer of the car body, it is necessary to use lifting equipment to lift the car body, so that the car body is lowered into the electrophoretic pool for immersion and the car body is lifted from the electrophoretic pool. The lifting equipment includes a car body lifting rack for mounting the car body and a lifting structure acting on the car body lifting rack. Since the electrophoretic pool contains a large amount of electric charge, these charges will be transmitted to the lifting structure through the car body lifting rack, and then transmitted to the electronic components above by the lifting structure, which is easy to cause a short circuit of the electronic control equipment. Therefore, the lifting structure needs to be insulated. Although the traditional lifting structure has been insulated, there is still the possibility of insulation failure or failure to completely block the charge phenomenon. Therefore, how to design an electrophoretic lifting equipment with good insulation effect has become a problem that needs to be solved urgently. Utility Model Content

[0004] The technical solution adopted in this application is:

[0005] A vehicle body electrophoresis lifting device comprises a vehicle body lifting frame and an insulating lifting structure connected to the vehicle body lifting frame. The vehicle body lifting frame is lowered into or lifted out of the electrophoresis pool by lifting the insulating lifting structure. The insulating lifting structure comprises an upper lifting assembly connected to the lifting device, a lower lifting assembly connected to the vehicle body lifting frame, and extensions respectively connected to the upper lifting assembly and the lower lifting assembly. The upper lifting assembly is provided with a first insulating portion, and the lower lifting assembly is provided with a second insulating portion.

[0006] The vehicle body electrophoresis lifting equipment described in this application also includes the following additional technical features:

The two side plates are respectively located on both sides of the reinforcing plate so that the extension piece has a U-shaped structure.

[0009] The upper lifting assembly includes an upper lifting member connected to the lifting device, a first connecting member connected to the extension member, and a first positioning member fixing the upper lifting member to the first connecting member, and the first insulating portion is located between the upper lifting member and the extension member.

[0010] The upper lifting member includes an upper lifting portion and a first matching portion, the first positioning member has a first positioning plate for fixing the upper lifting member, the first positioning member has a first locking state that locks with the first matching portion to fix the upper lifting member to the first positioning plate, the first insulating portion includes two first insulating gaskets and a second insulating gasket respectively located on both sides of the first positioning plate, when the first positioning member is in the first locking state, the first insulating gasket respectively abuts against the upper lifting member and the first positioning plate, and the second insulating gasket respectively abuts against the first positioning member and the first positioning plate.

[0012] The lower lifting assembly includes a lower lifting member connected to the lifting device, a second connecting member connected to the extension member, and a second positioning member fixing the lower lifting member on the second connecting member, and the second insulating portion is located between the lower lifting member and the extension member.

[0013] The lower lifting member includes a lower lifting portion and a second matching portion, the second positioning member has a second positioning plate for fixing the lower lifting member, the second positioning member has a second locking state that locks with the second matching portion to fix the lower lifting member to the second positioning plate, the second insulating portion includes two third insulating gaskets and a fourth insulating gasket respectively located on both sides of the second positioning plate, when the second positioning member is in the second locking state, the third insulating gasket respectively abuts against the second matching portion and the second positioning plate, and the fourth insulating gasket respectively abuts against the lower lifting member and the second positioning plate.

[0014] The number of the insulating lifting structures is two.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0016] 1. The insulating lifting structure in the vehicle body electrophoresis lifting equipment of the present application includes an upper lifting assembly and a lower lifting assembly, and the upper lifting assembly and the lower lifting assembly are respectively provided with a first insulating part and a second insulating part. When the charge in the electrophoretic pool is transmitted upward through the insulating lifting structure, it will be weakened by the second insulating part and the first insulating part in turn. Most of the charge in the electrophoretic pool transmitted to the insulating lifting structure through the vehicle body and the vehicle body lifting frame is absorbed by the second insulating part in the lower lifting assembly, and the residual charge that is not absorbed is blocked for the second time under the insulating effect of the first insulating part, which greatly reduces the transmission of the charge to the electronic equipment located above the insulating lifting structure. possibility; in addition, since an extension piece is provided between the upper lifting and placing component and the lower lifting and placing component in the present application, when the second insulating portion fails to intercept all the charges and causes part of the charges to move from the lower lifting and placing component to the upper lifting and placing component, the charges can be fully dissipated into the external air during the movement in the extension piece, thereby greatly weakening the amount of charges transferred in the upper lifting and placing component. When the amount of charges is small, they can even be completely dissipated into the air during the movement of transmission through the extension piece. That is, by providing the extension piece, the small amount of charges escaping from the lower lifting and placing component can be weakened or eliminated, thereby further improving the insulation performance of the insulating lifting structure.

[0017] 2. As a preferred embodiment of the present application, the distance between the first insulating part and the second insulating part is not less than 30 cm. Such a configuration can, on the one hand, increase the transmission time of the charge from the lower lifting assembly through the extension to the upper lifting assembly, thereby increasing the frequency of the charge escaping to the outside air when moving in the extension; on the other hand, a safe interval is reserved for the upper lifting assembly and the lower lifting assembly, that is, when too much charge accumulates in the lower lifting assembly and an arc is generated, since the arc can be conducted through the air, the distance between the first insulating part and the second insulating part is set to be not less than 30 cm, providing a dissipation length for the arc in the air, avoiding the charge in the lower lifting assembly from being directly transferred to the upper lifting assembly in the form of an arc conducted in the air, and further improving the insulation performance of the insulating lifting structure.

[0035] like Figures 1 to 5 As shown, a vehicle body electrophoresis lifting device includes a vehicle body lifting frame 1 and an insulating lifting structure 2 connected to the vehicle body lifting frame 1. The vehicle body lifting frame 1 is lowered into or lifted out of the electrophoresis pool by lifting the insulating lifting structure 2. The insulating lifting structure 2 includes an upper lifting assembly 3 connected to the lifting device, a lower lifting assembly 4 connected to the vehicle body lifting frame 1, and an extension member 5 respectively connected to the upper lifting assembly 3 and the lower lifting assembly 4. The upper lifting assembly 3 is provided with a first insulating portion 31, and the lower lifting assembly 4 is provided with a second insulating portion 41.

[0036] The insulating hoisting structure 2 in the vehicle body electrophoresis hoisting device of the present application includes an upper lifting assembly 3 and a lower lifting assembly 4, and the upper lifting assembly 3 and the lower lifting assembly 4 are respectively provided with a first insulating portion 31 and a second insulating portion 41. When the charge in the electrophoretic pool is transmitted upward through the insulating hoisting structure 2, it will be weakened by the second insulating portion 41 and the first insulating portion 31 in turn. Most of the charge in the electrophoretic pool transmitted to the insulating hoisting structure 2 through the vehicle body and the vehicle body lifting frame 1 is absorbed by the second insulating portion 41 in the lower lifting assembly 4, and the residual charge that is not absorbed is blocked for a second time under the insulating effect of the first insulating portion 31, which greatly reduces the charge from being transmitted to the electronic equipment located above the insulating hoisting structure 2. In addition, since an extension piece 5 is provided between the upper lifting component 3 and the lower lifting component 4 in the present application, when the second insulating portion 41 fails to intercept all the charges and causes part of the charges to move from the lower lifting component 4 to the upper lifting component 3, the charges can be fully dissipated into the outside air during the movement in the extension piece 5, greatly weakening the amount of charges transmitted in the upper lifting component 3. When the amount of charge is small, it can even be completely dissipated into the air during the movement of transmission through the extension piece 5. That is, by providing the extension piece 5, the small amount of charges escaping from the lower lifting component 4 can be weakened or eliminated, further improving the insulation performance of the insulating lifting structure 2.

[0037] As a preferred embodiment of the present application, the distance between the first insulating part 31 and the second insulating part 41 is not less than 30 cm. Such a setting can, on the one hand, increase the transmission time of the charge from the lower lifting assembly 4 through the extension 5 to the upper lifting assembly 3, thereby increasing the frequency of the charge escaping to the outside air when moving in the extension 5; on the other hand, a safe interval is reserved for the upper lifting assembly 3 and the lower lifting assembly 4, that is, when the charge accumulates too much in the lower lifting assembly 4 and an arc is generated, since the arc can be conducted through the air, the distance between the first insulating part 31 and the second insulating part 41 is set to be not less than 30 cm, providing a dissipation length for the arc in the air, avoiding the charge in the lower lifting assembly 4 from being directly transported to the upper lifting assembly 3 in the form of an arc conducted in the air, and further improving the insulation performance of the insulating hoisting structure 2.

[0038] As a preferred implementation of the present application, Figure 2 As shown, the extension member 5 includes two side panels 51 that are opposite to each other and extend in the vertical direction, and a reinforcing plate 52 connected to the two side panels 51. The two side panels 51 are respectively located on both sides of the reinforcing plate 52 so that the extension member 5 is in a U-shaped structure. Preferably, the side panels 51 and the reinforcing plate 52 are integrally formed. Such an arrangement can improve the structural strength of the extension member 5, reduce the difficulty of assembling the side panels 51 and the reinforcing plate 52 after being manufactured separately, and reduce the difficulty of assembling the insulating hanging structure 2.

[0039] As a preferred implementation of the present application, Figure 3 As shown, the upper lifting and placing assembly 3 includes an upper lifting and placing member 32 connected to the lifting and placing device, a first connecting member 33 connected to the extension member 5, and a first positioning member 34 for fixing the upper lifting and placing member 32 to the first connecting member 33, and the first insulating portion 31 is located between the upper lifting and placing member 32 and the extension member 5. In this way, the upper lifting and placing member 32, the first connecting member 33, and the first positioning member 34 can be manufactured separately and then assembled, so that it is convenient to design an upper lifting and placing member 32 that matches the structural form of the upper lifting device, and to set a first connecting member 33 that matches the structural form of the extension member 5, thereby optimizing the structural design of the upper lifting and placing assembly 3. At the same time, it is convenient for designers to design the first insulating portion 31 that matches the upper lifting and placing member 32 and the first connecting member 33 according to their structural forms, thereby further optimizing the structural design of the upper lifting and placing assembly 3.

[0040] As a preferred embodiment of this implementation, Figure 3 As shown, the upper lifting member 32 includes an upper lifting portion 321 and a first matching portion 322, the first positioning member 34 has a first positioning plate 341 for fixing the upper lifting member 32, the first positioning member 34 has a first locking state that is locked with the first matching portion 322 to fix the upper lifting member 32 to the first positioning plate 341, the first insulating portion 31 includes two first insulating gaskets 311 and a second insulating gasket 312 respectively located on both sides of the first positioning plate 341, when the first positioning member 34 is in the first locking state, the first insulating gasket 311 respectively abuts against the upper lifting member 32 and the first positioning plate 341, and the second insulating gasket 312 respectively abuts against the first positioning member 34 and the first positioning plate 341. With such arrangement, the first matching portion 322, on the one hand, has the function of fixing the upper lifting portion 321 to the first positioning plate 341, thereby realizing a stable installation of the upper lifting portion 321; on the other hand, the first matching portion 322 cooperates with the first positioning plate 341 to realize clamping and locking of the first insulating gasket 311, eliminating the need for a separate locking member for fixing the first insulating gasket 311, thereby optimizing the structural design of the upper lifting assembly 3; in addition, the first positioning member 34, on the one hand, locks the upper lifting member 32 to the first positioning plate 341, thereby realizing the function of installing the upper lifting member 32 in cooperation with the first matching portion 322, and at the same time integrates the function of clamping the second insulating portion 41 in cooperation with the first positioning plate 341, thereby eliminating the need for a separate locking member for fixing the second insulating gasket 312, thereby further integrating the functions and further optimizing the structural design of the upper lifting assembly 3.

[0041] This embodiment does not limit the structural form of the first connecting member 33 and the first matching portion 322, and they can adopt any one of the following examples:

[0042] Example 1: The first connector 33 is provided with a lower supporting portion 331 abutting against the second insulating gasket 312 , and the lower supporting portion 331 has a supporting surface 33 adapted to the shape of the second insulating gasket 312 .

[0043] Example 2: The first matching portion 322 includes a contact surface 3221 that is adapted in shape to the first insulating gasket 311 .

Such a configuration allows the second insulating gasket 312 to be better stabilized between the lower supporting portion 331 and the first positioning plate 341 in the clamping arrangement therebetween. The configuration of the supporting surface 33 enables the second insulating gasket 312 to better fit with the first positioning plate 341 and the first connecting member 33, thereby reducing the probability of charge transmission between the first positioning plate 341 and the first connecting member 33, thereby improving the insulation performance of the second insulating gasket 312. At the same time, by configuring the abutting surface 3221, the first insulating gasket 311 can be better stabilized between the first matching portion 322 and the first positioning plate 341 in the clamping arrangement therebetween, thereby reducing the probability of charge transmission between the first positioning plate 341 and the first matching portion 322, thereby improving the insulation performance of the first insulating gasket 311.

[0045] As a preferred implementation of the present application, Figure 3 As shown, the lower lifting and placing assembly 4 includes a lower lifting and placing member 42 connected to the lifting and placing device, a second connecting member 43 connected to the extension member 5, and a second positioning member 44 fixing the lower lifting and placing member 42 to the second connecting member 43, and the second insulating portion 41 is located between the lower lifting and placing member 42 and the extension member 5. In this way, the lower lifting and placing member 42, the second connecting member 43, and the second positioning member 44 can be manufactured separately and then assembled, so that it is convenient to design an adaptive lower lifting and placing member 42 according to the structural form of the vehicle body lifting and placing frame 1, and to set an adaptive second connecting member 43 according to the structural form of the extension member 5, thereby optimizing the structural design of the lower lifting and placing assembly 4, and at the same time, it is convenient for designers to design the second insulating portion 41 adapted to the upper lifting and placing member 32 and the second connecting member 43 according to their structural forms, further optimizing the structural design of the lower lifting and placing assembly 4.

[0046] As a preferred embodiment of this implementation, Figure 3 As shown, the lower lifting member 42 includes a lower lifting portion 421 and a second matching portion 422, the second positioning member 44 has a second positioning plate 441 for fixing the lower lifting member 42, the second positioning member 44 has a second locking state that locks with the second matching portion 422 to fix the lower lifting member 42 to the second positioning plate 441, the second insulating portion 41 includes two third insulating gaskets 411 and a fourth insulating gasket 412 respectively located on both sides of the second positioning plate 441, when the second positioning member 44 is in the second locking state, the third insulating gasket 411 respectively abuts against the second matching portion 422 and the second positioning plate 441, and the fourth insulating gasket 412 respectively abuts against the lower lifting member 42 and the second positioning plate 441. Such arrangement enables the second matching portion 422, on the one hand, to have the function of fixing the lower lifting portion 421 to the second positioning plate 441, thereby realizing a stable installation of the lower lifting portion 421; on the other hand, the second matching portion 422 cooperates with the second positioning plate 441 to realize clamping and locking of the third insulating gasket 411, thereby eliminating the need for separately setting a locking member for fixing the first insulating gasket 311, thereby optimizing the structural design of the upper lifting assembly 3; in addition, the second positioning member 44, on the one hand, locks the lower lifting member 42 to the second positioning plate 441, thereby realizing the function of installing the lower lifting member 42 in cooperation with the second matching portion 422, and at the same time integrates the function of clamping the fourth insulating portion in cooperation with the second positioning plate 441, thereby eliminating the need for separately setting a locking member for fixing the fourth insulating gasket 412, thereby further integrating the functions and further optimizing the structural design of the lower lifting assembly 4.

Preferably, the two insulating hoisting structures 2 are symmetrically distributed above the vehicle body lifting frame 1, which helps to improve the lifting stability of the vehicle body lifting frame 1 and reduce the occurrence of vehicle body loading instability caused by uneven force on the vehicle body lifting frame 1 during the lifting process.

[0048] The present application does not limit the number of insulating hoisting structures 2. In another embodiment, the number of insulating hoisting structures 2 may be set to four.
