Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a painting auxiliary tooling for a gantry crane cab. Background Art

[0002] As an important component of the vehicle, the cab needs to be painted to ensure its durability, corrosion resistance, and overall quality. Electrophoretic coating is one of the key steps in cab painting, and the hoist is the main tool for electrophoretic coating of the mobile cab. The existing cab painting hoist has problems with the cab shaking easily and poor stability, especially when only a single lifting rope is used to lift the cab. Therefore, multiple lifting ropes are often used to connect the mobile cab to improve stability. However, the lifting points of the multiple lifting ropes are distributed differently for cabs with different frame structures. The lifting points are set irrationally, and the cab as a whole is offset after being lifted, resulting in easy shaking and instability. Especially for cabs with special-shaped structures, the center of gravity is not easy to determine, and the lifting point setting is difficult. At the same time, due to the repeated entry of the lifting rope into the electrophoretic liquid, a layer of electrophoretic floating paint will be attached to the surface. This floating paint mixes with the lubricating oil on the conveyor chain to form sludge, which is difficult to completely remove during the degreasing and water washing process, thereby contaminating the electrophoretic tank liquid and the electrophoretic baking room, resulting in shrinkage holes in the electrophoretic paint film.

[0029] The length direction of the first guide rail 21 is the first direction; the length direction of the second guide rail 31 is the second direction; the length direction of the third guide rail 111 is the third direction; the first direction, the second direction and the third direction are perpendicular to each other.

[0030] like Figures 1 to 4 As shown in the embodiment, a painting auxiliary tool for a gantry crane cab includes:

[0031] Lifting mechanism 1;

[0032] The hoisting plate 2 is connected to the lifting mechanism 1 and moves along the third direction through the lifting mechanism 1. The hoisting plate 2 is provided with a first guide rail 21. The length direction of the first guide rail 21 is the first direction.

[0033] The sling limit seat 3 is connected to the first guide rail 21 and moves along the first direction. The sling limit seat 3 is provided with a second guide rail 31. The length direction of the second guide rail 31 is the second direction.

[0034] The slings 4 include a sling 41 and a sling connector 42. The slings 4 are connected to the sling limit seat 3 and move along the second guide rail 31. One end of the sling connector 42 is connected to the sling 41, and the other end is connected to the object 6 to be slinged.

[0035] The object-hanging connecting member 42 includes two opposing abutment plates 421, a plurality of rollers 422 disposed between the two abutment plates 421, and a first fastener 423 disposed on the rollers 422. The first fastener 423 abuts the two abutment plates 421 against the object to be hung 6, and the rollers 422 are configured to support the object to be hung 6.

[0036] The first direction, the second direction and the third direction are perpendicular to each other.

[0037] The first guide rail 21 allows the position of the sling 4 to be adjusted along a first direction; the second guide rail 31 allows the position of the sling 4 to be adjusted along a second direction; and the lifting mechanism 1 allows the height of the sling 4 to be adjusted along a third direction. This arrangement allows the sling 4 and the object to be hoisted 6 to be moved in three dimensions, facilitating adjustment of the lifting point and improving the stability of the object 6. Furthermore, the adjustable position of the sling 4 accommodates a variety of objects 6 with varying structures and centers of gravity, ensuring high stability for the objects 6 and expanding the scope of application of the present coating auxiliary tooling.

[0038] The object connecting member 42 is provided to connect the object to be hung 6 and the sling 41; a roller 422 is provided on the object connecting member 42, and the roller 422 supports the object to be hung 6 (that is, the roller 422 abuts against the top beam 61 of the object to be hung), and after the sling 4 lifts the object to be hung 6, the setting of the roller 422 facilitates the movement of the relative position of the object connecting member 42 and the object to be hung 6, that is, the fine adjustment of the position of the lifting point, further improving the balance of the object to be hung 6 after it is lifted, and improving the stability of the object to be hung 6.

[0039] By setting the first guide rail 21 and the second guide rail 31, the position of the sling 4 is easy to adjust and the adjustment accuracy is high; further, the movement of the sling limit seat 3 on the first guide rail 21 and the movement of the sling 4 on the second guide rail 31 are both controlled by the driving device, thereby improving the displacement accuracy.

[0040] Specifically, such as Figure 2 As shown, in this embodiment, the spreader limit seat 3 is controlled to move by the first drive device 8. After moving to the set position, the ends of the spreader limit seat 3 are locked to the lifting plate 2 by bolts. Furthermore, the first drive device 8 is a cylinder, which is fixedly connected to the spreader limit seat 3.

[0041] In this embodiment, the spreader 4 is controlled to move by the second driving device 9 . After moving to the set position, the spreader 4 and the spreader limit seat 3 are locked by bolts.

[0042] Providing multiple slings 4 to lift the object 6 to be lifted improves the stability of the object 6 to be lifted compared to a single sling 4 .

[0043] Furthermore, at least two first guide rails 21 are spaced apart along the second direction.

[0044] By providing at least two first guide rails 21 , the stability of the sling limiting seat 3 connected to the first guide rails 21 is ensured.

[0045] Furthermore, the sling limiting seat 3 is connected to the first guide rail 21 through the second slider 7 and moves along the first direction.

[0046] Furthermore, at least two sling limiting seats 3 are provided.

[0047] By providing at least two spreader limiting seats 3 , the spacing between different spreader limiting seats 3 along the second direction can be adjusted, and thus the spacing between the spreaders 4 provided on different spreader limiting seats 3 can be adjusted.

[0048] The position of the sling 4 in the plane where the second direction and the third direction intersect is adjustable, and the spacing between the slings 4 is adjusted to make the force at each lifting point uniform, thereby improving the stability of the object to be lifted 6; further, it can better adapt to objects to be lifted 6 with more structures and shapes, thereby expanding the application scope of the tooling of the utility model.

[0049] like Figure 4As shown, in another preferred embodiment, the hanging object connector 42 also includes a limiting hole 424 and a second fastener 425. The two abutment plates 421 are both provided with a limiting hole 424. The second fastener 425 connects the two limiting holes 424 and is pressed onto the top beam 61 of the object to be hung.

[0050] The setting of the second fastener 425, on the one hand, adjusts and fixes the relative positions of the two abutment plates 421, so that the two abutment plates 421 are clamped on the top beam 61 of the object to be hoisted and locked; on the other hand, in the third direction, the second fastener 425 cooperates with the roller 422 to be clamped on the top beam 61 of the object to be hoisted and locked; thereby enhancing the stability of the connection between the object to be hoisted 6 and the hoisting object connector 42.

[0051] like Figures 1 to 4 As shown, in another preferred embodiment, the sling 41 is a sling rod, a rope or an iron chain.

[0052] The sling 41 is configured as a boom structure, and the linkage between the two ends of the sling 41 is better, that is, when the sling 4 moves, the two ends of the sling 41 are ensured to move synchronously to adjust the balance of the object 6 to be hoisted.

[0053] Furthermore, the heavier the sling 41 is, the less likely it is to shake, which is beneficial to improving the stability of the object to be hoisted 6.

[0054] like Figure 3 As shown, at least one sling 41 includes an elastic section 411 and two fixed-length sections 412 , and both ends of the elastic section 411 are fixedly connected to the fixed-length sections 412 .

[0055] By observing the expansion and contraction of the elastic section 411, the balance of the object to be hung 6 and the stress conditions of the sling 4 at each position can be judged, and then the position of the sling 4 can be moved and adjusted to improve the balance of the object to be hung 6 in the hoisting state and improve the stability of the object to be hung 6.

[0056] Furthermore, the elastic section 411 is configured as a gas spring to achieve the extension and retraction of the sling 41 .

[0057] like Figures 1 and 2 As shown, in another preferred embodiment, the sling 4 further includes a third slider 43 , and the sling 41 is detachably connected to the third slider 43 and is connected to the sling limiting seat 3 through the third slider 43 .

[0058] The sling 41 is detachably connected to the third slider 43 , which facilitates replacement of the sling 41 and prevents the stains remaining on the surface of the sling 41 due to long-term and repeated immersion in the electrophoretic fluid from affecting subsequent painting.

[0059] Furthermore, the movement of the third slider 43 along the second guide rail 31 is controlled by the second drive device 9, thereby improving displacement accuracy. Specifically, in this embodiment, the second drive device 9 includes a lead screw 91 and a rotary motor 92. The sling 4 is connected to the sling limit seat 3 via the third slider 43. The third slider 43 is mounted on the lead screw 91, which is connected to the rotary motor 92. The third slider 43 is controlled by rotating the lead screw 91 to move on the second guide rail 31 of the sling limit seat 3.

[0060] like Figure 1 As shown, in another preferred embodiment, the lifting mechanism 1 includes two columns 11 and a beam 12 arranged between the two columns 11. The beam 12 is provided with a crane 13. The crane 13 is connected to the lifting plate 2 and drives the lifting plate 2 to move along the third direction.

[0061] like Figures 1 and 2 As shown, in another preferred embodiment, a third guide rail 111 is provided along the third directional column 11 , and the third guide rail 111 is provided with a first slider 5 , which is connected to the hanging plate 2 and enables the hanging plate 2 to move along the third guide rail 111 .

[0062] The crane 13 drives the hoisting plate 2 fixedly connected thereto to move along the third guide rail 111 , thereby achieving the lifting of the object 6 to be lifted.

[0063] The lifting mechanism 1 and the sling 41 cooperate with each other, and both extend along the third direction, so that the object to be lifted 6 can be immersed in or separated from the electrophoresis liquid, thereby improving the stability of the object to be lifted 6.

[0064] Furthermore, the first sliding block 5 cooperates with the third guide rail 111 to connect with the hanging plate 2 , thereby enhancing the stability of the hanging plate 2 during movement and preventing the hanging plate 2 from shaking.

[0065] In this embodiment, the electrophoretic liquid pool is arranged directly below the lifting mechanism 1 along the third direction. Furthermore, the electrophoretic liquid pool is arranged below the base 14 of the lifting mechanism 1 along the third direction.

[0066] Furthermore, the movement of the object to be hoisted 6 in the third direction is controlled by the crane 13 , thereby ensuring the accuracy of height adjustment of the object to be hoisted 6 in the third direction.

[0067] like Figures 1 to 4 As shown, when the utility model sling 4 is used:

[0068] Step 1: Start the lifting mechanism 1 and connect the crane 13 to the hoisting plate 2; the hoisting plate 2 is connected to the first slide 5, which is disposed on the third guide rail 111; the crane 13 drives the hoisting plate 2 downward in the third direction until the connecting piece 42 connected to the hoisting plate 2 reaches the position of the top beam 61 of the object to be hoisted, and the movement of the lifting mechanism 1 is stopped;

[0069] Step 2: Preliminarily estimate the position of the lifting point (the lifting point is the connection point between the sling 4 and the object to be lifted 6), and connect the sling 4 to the top beam 61 of the object to be lifted according to the estimated position;

[0070] Step 3: Start the lifting mechanism 1 again to lift the object 6 so that the object 6 is suspended in the air;

[0071] Step 4: Observe the expansion and contraction of the elastic section 411 in the sling 41 to determine the deflection of the object 6 after lifting and adjust the position of the sling 4 to balance the forces on each sling 4 and achieve a balanced state of the object 6 (if the deflection is not large, the elastic section 411 can achieve self-adjustment of the stability of the object 6). Specifically, if the elastic section 411 is extended, the sling 41 is subjected to greater force at that location, and vice versa. The stability of the object 6 is adjusted by adjusting the position of the sling 4.

[0072] Step 5: Lock the lifting device 4 and the object to be lifted 6; start the lifting mechanism 1, and immerse the object to be lifted 6 in the electrophoretic liquid for coating.

[0073] 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 modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
