[0060] Embodiment 1

[0061] A cast lifting device, comprising: an electric control sliding assembly 1, a lifting assembly, a suspension assembly and a cast support tray 7.

[0062] The lifting device provided by the utility model is arranged below the running slide rail of the shot blasting machine and can slide on the running slide rail, realizes the transfer of the cast to be processed into the shot blasting machine for processing or the transfer of the cast processed by the shot blasting out of the shot blasting machine; the slide rail usually adopts a "I-steel" slide rail; the electric control sliding assembly 1 is slidably arranged on the slide rail.

[0063] As shown in Figure 2 The electric control sliding assembly 1 in the embodiment comprises a slide 101, a pulley 102 and a motor 8.

[0064] The slide 101 is in a "U" shape structure, and the open end of the slide 101 is arranged upward, and a bearing rod is arranged on the inner wall of each side of the slide 101, and a set of pulleys 102 are arranged on the bearing rod; the first end of the bearing rod is arranged on the shaft of the pulley 102, and the second end is rotatably arranged on the inner wall of the slide 101;

[0065] The first end of the bearing rod on the inner wall of one side of the slide 101 is arranged on the pulley 102, and the second end penetrates the inner wall of the slide 101, and the entire bearing rod is rotatable relative to the slide 101, and the second end of the bearing rod penetrating the inner wall of the slide 101 is arranged on the rotor of the motor 8; the motor 8 is operated to drive the pulley 102 on one side to rotate;

[0066] As shown in Figure 7 , the pulleys 102 on both sides are movably arranged on the inner sides of the "I-beam" slide rail 10; the motor 8 drives the pulley 102 on one side to rotate, thereby driving the entire electric control sliding assembly 1 to move on the slide rail 10;

[0067] As a preferred embodiment, in order to ensure safety, a cross rod can also be arranged on the open upper side of the "U" shaped slide 101, but the cross rod does not contact the slide rail 10; in this way, if the pulley 102 falls off, the cross rod can be blocked on the slide rail 10, thereby avoiding the entire slide 101 and the structure below the slide 101 from falling off;

[0068] A lifting assembly is arranged below the slide 101, as shown in Figure 2 , the lifting assembly in the embodiment includes a winch 2, a sling 3 and a lifting pulley 301;

[0069] The winch 2 is fixedly arranged below the slide 101 through a connecting rod; the sling 3 is wound on the winch 2; the sling 3 can be a chain or a steel cable; the lifting pulley 301 is arranged below the winch 2, and the free end of the sling 3 penetrates the lifting pulley 301 and is fixedly arranged on one side of the winch 2 upward; the winch 2 controls the unwinding or winding of the sling 3, so that the lifting pulley 301 and the structure assembly below the lifting pulley 301 are synchronously lowered or lifted;

[0070] A suspension assembly is arranged below the lifting pulley 301, and a plurality of groups of casting support plates 7 are arranged on the suspension assembly at equal intervals from top to bottom, and the castings are placed on the casting support plates 7; as shown in Figure 1 , the suspension assembly in the embodiment includes a hook 5, a hooking buckle 602 and a main suspension rod 6;

[0071] The upper end of the hook 5 is arranged below the lifting pulley 301 of the lifting assembly; the hooking buckle 602 is movably arranged on the hook 5; the lower end of the hooking buckle 602 is vertically connected to the upper end of the main suspension rod 6; a plurality of groups of casting support plates 7 are arranged on the main suspension rod 6 at equal intervals. The castings to be processed are placed on the casting support plates 7 and are transferred to the shot blasting machine for processing.

[0072] In a preferred embodiment, the casting on the casting support tray 7 is transferred to the shot blasting machine. To facilitate rotation of the casting support tray 7 within the shot blasting machine for position adjustment, ensuring it is fully inserted into the machine; as... Figure 2 As shown, a universal joint 9 is provided between the hook 5 and the caster wheel 301; the universal joint 9 allows the hook 5 and the casting support tray 7 suspended below the hook 5 to rotate 360° relative to the caster wheel 301. When the casting support tray 7 is transferred into the shot blasting machine, if part of the casting support tray 7 is not yet safely inside the shot blasting machine, the casting support tray 7 can be rotated appropriately to ensure it is fully inside the shot blasting machine before closing the shot blasting machine door.

[0073] A through slot is cut in the center of the top of the shot blasting machine, such as... Figure 2 As shown, a bracket 4 is installed on the straight rod part of the hook 5; the bracket 4 has an inverted trapezoidal structure, and the cross section of the through groove is also set as an inverted trapezoid; the bracket 4 is inserted into the groove above the shot blasting machine for limiting, which can prevent the hook 5 and the structure suspended on the hook 5 from shaking significantly. During the shot blasting process, large shaking may cause the casting on the casting support tray 7 to fall off.

[0074] Normally, multiple sets of casting support trays 7 are coaxially connected in series on the main suspension rod 6. In order to ensure the quantity of castings placed in a batch, an appropriate number of sets of casting support trays 7 are needed. Therefore, the spacing between each set of casting support trays 7 cannot be too large. If the spacing between two adjacent sets of casting support trays 7 is too small, the castings placed on the inner side will inevitably be partially blocked, which may result in insufficient contact with the abrasive and affect the shot blasting effect.

[0075] like Figure 1 As shown, the casting support tray 7 in this embodiment is also set on the main suspension rod 6. Unlike the prior art, in this embodiment, two adjacent sets of casting support trays 7 are set in opposite directions. In order to ensure balance, it is best that the number of casting support trays 7 set on each side is the same. This arrangement structure increases the distance between the upper and lower sets of casting support trays 7 on the same side, which greatly reduces the range of castings placed on the inner side being blocked.

[0076] The structure of the casting support plate 7 and its connection with the main suspension rod 6 are as follows: Figure 3 As shown, a suspension rod fixing plate 703 is integrally formed on the side edge of the casting pallet 7; the main suspension rod 6 passes through the suspension rod fixing plate 703 to fix the casting pallet 7 to the main suspension rod 6.

[0077] As a preferred embodiment, to ensure the connection stability of the casting support plate 7 on the main suspension rod 6, such as Figure 1As shown, in addition to the lowermost group of cast support tray 7, the rest of the cast support tray 7 lower bottom surface and the main suspension rod 6 between the setting of inclined strut 601; the upper surface of the lowermost group of cast support tray 7 and the main suspension rod 6 between the setting of inclined strut 601. Through the inclined strut 601 to the cast support tray 7 play a supporting role in the auxiliary fixed.

[0078] The castings to be processed are neatly placed on the upper surface of each group of cast support tray 7, and the winch 2 controls the sling 3 to lift the cast support tray 7 to the appropriate height; the motor 8 controls the pulley 102, so that the slide 101 moves on the slide rail 10, driving the cast support tray 7 to move into the shot blasting machine; adjust the position of the cast support tray 7, so that it is completely located in the shot blasting machine, and the door of the shot blasting machine is closed; the castings can be treated by shot blasting.

[0079] Example 2

[0080] Based on the basis of example 1, in example 1, the spacing between the upper and lower groups of cast support tray 7 is increased, which reduces the mutual shielding between the cast support trays 7 and improves the shot blasting effect; but on the same group of cast support tray 7, the castings placed in the inner circle will inevitably be partially shielded by the castings placed in the outer circle, and the part that is shielded may not be fully treated by shot blasting.

[0081] As Figure 3 shown, the upper surface of the second support table 702 is higher than the upper surface of the cast support tray 7; the upper surface of the first support table 701 is higher than the upper surface of the second support table 702; only a height difference is needed between them, and the height difference does not need to be too large; it does not affect the overall spacing between the upper and lower two groups of cast support trays 7; in this way, the castings placed in the inner and outer circles are formed in a high-low staggered manner, which can minimize the shielding between the castings caused by the placement of the inner and outer circles;

[0082] As a preferred embodiment, a shaft 704 is passed through from the center of the lower bottom surface of the cast support tray 7 upwards; the shaft 704 is fixedly arranged with the first support table 701 and the second support table 702; the shaft 704 is rotatable relative to the cast support tray 7; the lower end of the shaft 704 is arranged on the rotor of the motor 8. The motor 8 drives, which can drive the first support table 701 and the second support table 702 to rotate, and keeps the first support table 701 and the second support table 702 rotating slowly and uniformly during the shot blasting process, so that the contact between the castings is more uniform, and the shot blasting effect is further improved.

[0083] Example 3

[0084] Based on Embodiment 2, in Embodiment 2, the upper surfaces of the primary support platform 701, the secondary support platform 702, and the casting support tray 7 have no protective shielding structure; the casting placed on the upper surface may slip off the side during the shot blasting process or transfer.

[0085] like Figure 5 As shown, in this embodiment, side railings 705 are provided on the outer edges of the casting support tray 7, the primary support platform 701 and the secondary support platform 702. Under the protection of the side railings 705, the castings placed on the upper surface of the casting support tray 7, the primary support platform 701 and the secondary support platform 702 can be prevented from sliding off the sides.

[0086] Example 4

[0087] Based on embodiment 2 or 3, in embodiment 2 or 3, the castings are stacked on the upper surfaces of the casting support tray 7, the primary support platform 701 and the secondary support platform 702; since the castings are adjacent to each other, a large area of ​​mutual obstruction will be formed between the castings.

[0088] like Figure 6 As shown, in this embodiment, several partition plates 706 are evenly spaced on the upper surfaces of the casting support tray 7, the primary support platform 701, and the secondary support platform 702. The partition plates 706 divide the upper surface placement space into several independent placement areas. Depending on the volume of the casting, 2 to 3 castings are placed in each independent placement area. This avoids all castings from sticking together and forming a large area of ​​mutual obstruction; it also makes the castings more neat and uniform in placement; and it facilitates counting.
