Description

Technical Field

[0001] The present application relates to the field of lifting technology, and in particular to a lifting device for painting large parts. Background Art

[0002] Large parts need to be painted before leaving the factory. For example, the integrated transmission box of a tank usually needs to be placed flat on a pallet when it is painted. The five sides are painted for the first time. After the five sides are dried, it is turned over and the bottom is painted. Because the integrated transmission box is heavy (weight is about 3000Kg), and the existing paint shop does not have a crane installed due to explosion-proof requirements, and many sides have special-shaped pipeline parts without a flat supporting surface, it is difficult to turn over the integrated transmission box, and it takes time and labor, which leads to low painting efficiency of the integrated transmission box.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0028] refer to Figures 1 to 3 The present application provides a lifting device for painting large parts, comprising:

[0029] The support frame 100 has a vertical slideway 101 disposed on one side of the support frame 100 and fixed pulleys 102 disposed on the tops of two opposite sides thereof.

[0030] The pneumatic hydraulic cylinder 200 is arranged on one side of the support frame 100 through the fixed plate 300, and the bottom end of the hydraulic rod of the pneumatic hydraulic cylinder 200 is rotatably provided with a movable pulley 201 matching the vertical slideway 101; wherein, the fixed plate 300 is arranged on the support frame 100, and the cylinder body of the pneumatic hydraulic cylinder 200 is fixed on the fixed plate 300. One movable pulley 201 corresponds to one vertical slideway 101, and the hydraulic rod of the pneumatic hydraulic cylinder 200 drives the movable pulley 201 rotatably connected thereto to move vertically up and down in the vertical slideway 101 during the extension and retraction process.

[0031] The chains 400 are two and one end of each chain is connected to the fixed plate 300. The other end of one of the chains 400 is connected to one side of the beam 500 by sequentially rotating around the movable pulley 201 and the fixed pulley 102 (the fixed pulley 102 is located above the movable pulley 201). The other end of the other chain 400 is connected to one side of the beam 500 by sequentially rotating around the pulley 201 and the two fixed pulleys 102 (the chain 400 passes through the movable pulley 201 first and then passes through the fixed pulley 102 above the movable pulley 201). 2, and then through the fixed pulley 102 arranged on the other side of the support frame relative to the movable pulley 201) connected to the other side of the crossbeam 500, so that the two chains 400 are respectively connected to the opposite sides of the crossbeam 500 to ensure the balance and stability of the crossbeam 500 during the lifting process, and the crossbeam 500 is connected to the integrated transmission box 501 below through the suspension chain 600, and the crossbeam 500 can drive the integrated transmission box 501 to rise and fall below the inner top surface of the support frame 100. Among them, during the vertical up and down movement of the movable pulley 201 in the vertical slideway 101, it drives the chain 400 wound thereon to move vertically up and down, thereby lifting and lowering the crossbeam 500 connected to the chain 400 and the integrated transmission box 501 connected to the bottom of the crossbeam 500 through the suspension chain 600. The lifting device for painting large parts provided by the present application drives the movable pulley 201 arranged thereon to move vertically up and down by telescoping the hydraulic rod of the pneumatic hydraulic cylinder 200, and one end of one chain 400 away from the fixed plate 300 is connected to one side of the beam 500 by winding around the movable pulley 201 and the fixed pulley 102, while the other end of the chain 400 away from the fixed plate 300 is connected to the other side of the beam 500 by winding around the movable pulley 201 and the two fixed pulleys 102. That is to say, both chains 400 are wound around the fixed pulley 102 and are moved up and down by the movable pulley 201. The movement is used to pull up and down, so that the crossbeam 500 is pulled up or down through the chain 400, thereby realizing the lifting and lowering of the integrated transmission box 501 connected to the bottom of the crossbeam 500 through the lifting chain 600. After the integrated transmission box 501 rises to a certain height, it is convenient to paint all surfaces of the integrated transmission box 501 at one time, avoiding the situation of painting the five surfaces of the integrated transmission box 501 for the first time, waiting for the five painted surfaces to dry, turning it over and then painting the bottom surface, saving time and labor, and improving the painting efficiency of the integrated transmission box 501.In addition, since the paint spray room is originally an enclosed space with a certain concentration of particulate matter, that is, when the concentration of particulate matter in the paint spray room reaches a certain concentration, the paint spray room is prone to explosions, fires and other dangers. Therefore, it is not suitable to use a crane to lift the integrated transmission box 501 (the power of the crane is provided by electricity, that is, when the integrated transmission box is lifted by a crane, explosion-proof settings are required, and improper explosion-proof settings may cause leakage and sparks, which may cause explosions, fires, etc. in the paint spray room). The present application uses a pneumatic hydraulic cylinder 200 as the power for lifting the integrated transmission box 501, does not involve the use of electricity, and thus reduces the risk of explosions in the paint spray room, thereby improving the safety of the painting process in the paint spray room.

[0032] The large parts in the present application may be an integrated transmission box 501 of a tank that needs to be painted, and the large parts may be other large parts that need to be hoisted for painting. The specific implementation method in the present application only takes the integrated transmission box 501 that needs to be hoisted for painting as an example, but is not limited to the integrated transmission box 501.

[0033] In some embodiments, reference Figure 1 The air inlet of the pneumatic hydraulic cylinder 200 in the present application is connected to a pneumatic hydraulic pump 2021 through a pneumatic tube 202. The pneumatic hydraulic pump 2021 converts the lower air pressure into high-pressure oil, that is, the low air pressure at the large-area piston end is used to generate the high hydraulic pressure at the small-area piston end. The pneumatic hydraulic pump 2021 provides power to the pneumatic hydraulic cylinder 200, thereby avoiding the risk of explosion in the paint spraying room caused by electric means (because when the concentration of particulate matter in the paint spraying room reaches a certain concentration, the paint spraying room is prone to explosion, fire, etc., therefore, the use of electric means requires explosion-proof settings, and improper explosion-proof may cause leakage to generate sparks, which may cause explosions, fires, etc. in the paint spraying room), thereby improving the safety of the painting process of the integrated transmission box 501.

[0034] In some embodiments, the air source of the pneumatic hydraulic pump 2021 in the present application is 0.5Mpa-0.8Mpa. The air source within this range can ensure that the pneumatic hydraulic cylinder 200 has enough power to make the crossbeam 500 and the integrated transmission box 501 connected to the bottom of the crossbeam 500 through the suspension chain 600 rise, and the specific value of the air source can be set according to actual conditions, and the present application does not make specific restrictions on it.

[0035] In some embodiments, reference Figure 2There are four fixed pulleys 102 in the present application, and the four fixed pulleys 102 are respectively arranged at the four corners of the top of the support frame 100, and each fixed pulley 102 is provided with two first annular grooves 1021; the bottom end of the hydraulic rod of the pneumatic hydraulic cylinder 200 is provided with a connecting rod 203 perpendicular to its hydraulic rod, and the two ends of the connecting rod 203 are respectively rotatably provided with movable pulleys 201 and each movable pulley 201 is provided with two second annular grooves 2011; wherein, there are two vertical slideways 101, and the two vertical slideways 101 correspond one to one to the two movable pulleys 201.

[0036] There are four chains 400, and each movable pulley 201 corresponds to two chains 400. Each chain 400 can be pulled in the corresponding first annular groove 1021 and the second annular groove 2011, so that the four corners of the beam 500 are connected with chains 400, so that the beam 500 can be raised or lowered under the simultaneous pulling of four chains 400, thereby improving the balance and stability of the lifting process of the beam 500 and the integrated transmission box 501 connected to its lower surface through the lifting chain 600.

[0037] In the above embodiment, when the hydraulic rod of the pneumatic hydraulic cylinder 200 is extended, its hydraulic rod drives the connecting rod 203 arranged thereon downward, and the two movable pulleys 201 connected to the connecting rod 203 are rotatably connected to slide downward in the corresponding vertical slideway 101, thereby driving the chain 400 wound in its second annular groove 2011 to be pulled downward by the downward force from the movable pulley 201, so that the chain 400 connected to the beam 500 moves upward, thereby realizing the rise of the beam 500 and the integrated transmission box 501 connected to the bottom of the beam 500 through the suspension chain 600, and when the hydraulic rod of the pneumatic hydraulic cylinder 500 is contracted, its hydraulic rod drives the connecting rod 203 arranged thereon upward, and the rotating The two movable pulleys 201 movably connected to the connecting rod 203 slide upward in the corresponding vertical slideway 101, and the pressure of the movable pulley 201 on the chain 400 wound in its second annular groove 2011 disappears, and the end of the chain 400 connected to the beam 500 is pulled downward by the gravity of the beam 500 and the integrated transmission box 501 connected to the bottom of the beam 500 through the lifting chain 600, thereby realizing the descent of the integrated transmission box 501, and the descent distance is equal to the extension and retraction length of the hydraulic rod of the pneumatic hydraulic cylinder 200, thereby realizing the lifting and lowering of the beam 500 and the integrated transmission box 501 connected to the bottom of the beam 500 through the lifting chain 600.

[0038] In some embodiments, the fixed pulley 102 and the movable pulley 201 in the present application are both made of nylon or brass. Since during the lifting process of the crossbeam 500, the chain 400 pulls and generates friction with the movable pulley 201 and the fixed pulley 102, and since the paint spraying room is originally a closed space with a certain concentration of particulate matter, that is, the paint spraying room is a dangerous place that is prone to explosions, fires, etc., therefore, in order to avoid the situation where static electricity is generated due to friction between the chain 400 and the movable pulley 201 or the fixed pulley 102, which may cause a fire in the paint spraying room, the fixed pulley 102 and the movable pulley 201 are set to nylon or brass material to prevent static electricity from being generated between the chain 400 and the movable pulley 201 or the fixed pulley 102, thereby ensuring the safety of the paint spraying room.

[0039] In some embodiments, reference Figure 3 In the present application, guide grooves 103 are arranged on opposite sides of the support frame 100, and opposite sides of the cross beam 500 respectively move vertically up and down in the corresponding guide grooves 103. In the process of the cross beam 500 moving up and down, the opposite sides are always in the corresponding guide grooves 103, so as to avoid the cross beam 500 from deflecting during the lifting process, thereby making the lifting process of the integrated transmission box 501 more stable.

[0040] In some embodiments, reference Figure 2 In the present application, first sockets 502 are respectively provided on opposite sides of the crossbeam 500, and second sockets 104 are respectively provided on opposite sides of the support frame 100 at a preset distance from the top thereof. The two first sockets 502 correspond to the two second sockets 104 one by one, and each first socket 502 and each second socket 104 are connected by a pin 700.

[0041] In the above embodiment, the difference between the distance between the inner top of the support frame 100 and the bottom thereof and the preset distance (which can be set according to actual needs and is not specifically limited in the present application) is the stroke of the rising beam 500 (which can be 600 mm, depending on the needs of the actual painting process), and when the beam 500 rises to this height, it is convenient to spray paint on all surfaces of the integrated transmission box 501. Specifically, when the beam 500 rises to this height, the first plug holes 502 on the left and right sides of the beam 500 and the first plug holes 502 on the support frame 100 are in contact with each other. The second sockets 104 correspond one to one, and the crossbeam 500 and the support frame 100 are fixed together by means of the pin 700 which passes through the first socket 502 and the second socket 104 in sequence, so as to play a mechanical locking role in special circumstances such as the breakage of the chain 400, so as to avoid the crossbeam 500 and the integrated transmission box 501 connected to the crossbeam 500 through the suspension chain 600 suddenly falling due to the breakage of the chain 400, causing casualties and damage to parts in the integrated transmission box 501, thereby improving the stability of the integrated transmission box 501 during the painting process.

[0042] In some embodiments, reference Figure 1 There are multiple lifting chains 600 in the present application, and the multiple lifting chains 600 are evenly spaced on the lower surface of the beam 500; specifically, one end of each lifting chain 600 is fixedly connected to the lower surface of the beam 500, and a lifting ring 601 is provided at the bottom end of each lifting chain 600, and a lifting hook 5011 is provided on the integrated transmission box 501, and the lifting hook 5011 matches the lifting ring 601.

[0043] In the above embodiment, the hook 5011 on each integrated transmission box 501 is hung on the ring 601 of the corresponding hanging chain 600 to achieve the connection between the integrated transmission box 501 and the crossbeam 500. Since the weight of the integrated transmission box 501 is relatively large, and a plurality of hanging chains 600 are arranged on the lower surface of the crossbeam 500, the weight of the integrated transmission box 500 can be evenly distributed on the plurality of hanging chains 600, avoiding the situation that a certain hanging chain 600 is overstressed and broken, thereby ensuring the stability of the lifting process of the integrated transmission box 500. In addition, the number of the hanging chains 600 can be set according to actual conditions, and therefore, the present application does not specifically limit it here.

[0044] In some embodiments, reference Figure 1 The lifting device in the present application further includes a transfer bracket 800, which is used to transfer the integrated transmission box 501 thereon to change the position of the integrated transmission box 501 relative to the ground. The transfer bracket 800 facilitates the integrated transmission box 501 to be painted to move toward the support frame 100 and makes the integrated transmission box 501 located directly below the crossbeam 500. After the painting process is completed and the paint on each surface is completely dry, the painted integrated transmission box 501 is placed on the transfer bracket 800 and removed by the transfer bracket 800. Since the integrated transmission box 501 is heavy, it is more labor-saving to move the integrated transmission box 501 by the transfer bracket 800, thereby improving the portability of the integrated transmission box 501.

[0045] In some embodiments, reference Figure 1 The bottom of the support frame 100 in the present application is connected to the ground through anchor bolts 900. The ground refers to the ground in the spray paint room where the support frame 100 is placed. The bottom of the support frame 100 is fixed to the ground through anchor bolts 900, in order to improve the stability of the support frame 100 relative to the ground, so that the lifting process of the integrated transmission box 501 is more stable when the integrated transmission box 501 is sprayed with paint.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features therein may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
