Description

Technical Field

[0001] The utility model belongs to the technical field of casting material transfer, and particularly relates to an auxiliary transfer device. Background Art

[0002] In investment casting, firing is an important step; firing is to bake the coating applied to the surface of the investment at high temperature to achieve the effect of controlling the surface condition of the investment and enhancing thermal stability; in order to facilitate the placement of the investment during firing, the investment must be taken out after firing is completed; the operator has designed a rack specifically for transferring the investment, which is a ring-shaped structure, and the investment can be stuck in the ring-shaped structure; a horizontal bar is set on each side of the ring-shaped structure; during firing, a hook is set on the structure for placing the investment, and the horizontal bars on both sides of the ring are hung on the hooks, so that the investment is suspended for firing; after firing is completed, the operator holds the horizontal bars on both sides to take away the investment and transfer it, and the horizontal bars on both sides can prevent the hands from directly touching the surface of the investment.

[0003] However, the transfer of the investment mold is still a manual operation. During the operation, especially after the melting is completed, the ring and the cross bars on both sides are still warm, so the operator needs to wear heat-insulating gloves to operate. However, heat-insulating gloves cannot completely insulate, and this process may still cause burns to the operator due to heat radiation. Utility Model Content

DETAILED DESCRIPTION

[0057] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] Example 1

[0059] An auxiliary transfer device, comprising: a support 1, a rotating shaft seat 3, a cross brace, a hook 20, a suspension rod 4 and a counterweight assembly;

[0060] like Figure 1 As shown, the pillar 1 serves as the supporting main structure of the entire transfer device, and the pillar 1 is set as a cylindrical structure; the lower end of the pillar 1 needs to be fixed on the flat ground; in this embodiment, a chassis 101 is set at the lower end of the pillar 1, and a plurality of bolt holes are opened on the chassis 101. Bolts are driven into the bolt holes and the bolts are driven into the ground, so that the pillar 1 can be fixed to the ground.

[0061] A circular support plate is provided at the upper end of the pillar 1, and a shaft 2 is provided on the support plate, and a rotating shaft seat 3 is rotatably sleeved on the outer periphery of the shaft 2; Figure 5 As shown, the shaft 2 is divided into two sections, the outer diameter of the first section of the shaft is smaller than that of the second section of the shaft, and the lower end of the second section of the shaft is set on the above-mentioned circular support plate; the upper end of the first section of the shaft is detachably provided with a limit cover plate 201 through a thread; the bottom of the shaft seat 3 is an open structure, the interior of the shaft seat 3 is hollow, and the shape of the hollow structure is the same as the outer shape contour of the entire shaft 2; the shaft seat 3 is rotatably sleeved on the outer periphery of the shaft 2, and the upper end of the first section of the shaft extends out of the upper end of the shaft seat 3, and then a limit cover plate 201 is set on the upper end of the first section of the shaft by screwing. The limit cover plate 201 can prevent the shaft seat 3 from falling off the shaft 2; and combined with the two sections of the shaft with different outer diameters, the shaft seat 3 will not shift up and down.

[0062] like Figure 1 As shown, the first end of a horizontal support rod is horizontally mounted on the outer wall of the rotating shaft seat 3; a bearing sleeve is mounted on the second end of the horizontal support rod, and a shaft is rotatably mounted within the bearing sleeve. A hook 20 is mounted at the lower end of the shaft rod, with two hooks 20 disposed on opposite sides, each located below a horizontal plate and near each end of the plate. The lower end of the shaft rod is centrally mounted on the upper surface of the horizontal plate.

[0063] Located on the outer wall of the rotating shaft seat 3 and on the opposite side of the cross brace, the first end of a suspension rod 4 is also horizontally arranged, and a counterweight assembly is arranged on the second end of the suspension rod 4 through a suspension rope 5; the counterweight assembly is used to maintain the balance of the hook 20 side.

[0064] If the length of the cross brace is fixed, the rotation range of the cross brace is limited, and the investment material can only be hooked and transferred within the area covered by the length of the cross brace; Figure 1 As shown, as a preferred embodiment, the cross brace is configured as a telescopic structure, comprising: a base section rod 7 and a telescopic rod 8; the first end of the base section rod 7 is transversely arranged on the side wall of the rotating shaft seat 3; the first end of the telescopic rod 8 extends from the second end of the base section rod 7 into the base section rod 7 and is telescopic relative to the base section rod 7; a locking screw is provided on the side wall of the base section rod 7; a screw hole is formed on the side wall of the telescopic rod 8; after adjusting the position of the telescopic rod 8 to an appropriate length, the locking screw is screwed into the corresponding screw hole; thus, the telescopic rod 8 can be fixed to the base section rod 7 to maintain its inherent length;

[0065] The hook 20 is still the same as above, and is rotatably arranged on the second end of the telescopic rod 8 through the bearing sleeve and the cross plate.

[0066] When the hook 20 is being transferred, in order to prevent the hook 20 from touching the material below, it is best that the hook 20 and the material thereon can be properly lifted, and after the transfer reaches the destination, it is properly lowered to separate the material from the hook 20; as a preferred embodiment, Figure 3 As shown, two hinged plates 901 are vertically provided at the second end of the telescopic rod 8; a hinged shaft 902 is provided between the two hinged plates 901 and close to the upper and lower sides of the hinged plates 901; and the first end of a lifting movable rod 9 is connected to each of the two hinged shafts 902;

[0067] like Figure 2 As shown, a hinge shaft 902 is also provided on the second end of each of the two lifting movable rods 9, and the hinge shaft 902 is also provided between the two hinge plates 901; a hook 20 is rotatably provided on the outer side of the hinge plate 901; the hook 20 is also rotatably provided through the bearing sleeve and the cross plate as described above;

[0068] On the lifting movable rod 9, a lifting assembly is provided, which is used to control the lifting or lowering of the lifting movable rod 9. Figure 1 As shown, the lifting assembly includes: a vertical support rod 10, a winch 12, a first pulley 13, a second pulley 14 and a pulling rope 11;

[0069] A vertical support rod 10 is provided at the second end near the top of the base rod 7; a winch 12 is provided at the first end above the base rod 7; a first pulley 13 is provided at the upper end of the vertical support rod 10; a second pulley 14 is provided at the second end above the lifting movable rod 9; a pulling cable 11 is wound around the winch 12, and the free end of the pulling cable 11 passes through the first pulley 13 and the second pulley 14 and is placed on the second pulley 14. The winch 12 retracts the pulling cable 11, allowing the lifting movable rod 9 to rotate with the hinge at the first end as the fulcrum, that is, the lifting movable rod 9 can be lifted. The second end of the lifting movable rod 9 is hinged to the hinge plate 901, and a hook 20 is provided on the outside of the hinge plate 901, and the hook 20 is also lifted synchronously. Since the second end of the lifting movable rod 9 is hinged to the hinge plate 901, the hook 20 does not tilt during lifting and always remains vertically downward under the action of gravity. This can prevent the material on the hook 20 from tilting and sliding off.

[0070] After the investment material is placed on the hook 20, when the investment material needs to be transferred, it is achieved by rotating the entire cross brace; however, sometimes the range of rotation required is small, and rotating the entire cross brace is more laborious;

[0071] As a preferred embodiment, Figure 2 As shown, a first bearing sleeve 15 is provided on the outside of the hinged plate 901 at the second end of the lifting movable rod 9; a first shaft rod 16 is rotatably provided in the first bearing sleeve 15; a first end of a horizontal connecting rod 19 is provided near the lower end of the first shaft rod 16 and perpendicular to the first shaft rod 16; a second bearing sleeve 17 is provided at the second end of the horizontal connecting rod 19; a second shaft rod 18 is rotatably provided in the second bearing sleeve 17; the lower end of the second shaft rod 18 is centered on the upper surface of a horizontal plate; a hook 20 is provided below the horizontal plate and near both ends of the horizontal plate.

[0072] When transferring materials, only a small range of rotation transfer is required. It is only necessary to rotate the cross-link 19 with the first shaft 16 as the axis, that is, to rotate within the range of the length of the cross-link 19 as the radius; there is no need to rotate the entire cross-bracing rod, which is more labor-saving.

[0073] like Figure 1As shown, the counterweight assembly includes a counterweight box 6 and counterweights 601. One side of the counterweight box 6 is open. The interior of the box 6 is divided into several equal compartments by transverse partitions. A counterweight 601 is removably inserted into each compartment. The number of counterweights 601 is adjusted based on the weight of the transferred investment on the hook 20 to achieve weight balance on both sides.

[0074] like Figure 1 As shown, in order to ensure the stability of the entire suspension rod 4 and the counterweight assembly, an oblique support rod 401 is obliquely arranged between the bottom of the suspension rod 4 and the support 1; the suspension rod 4 is reinforced by the oblique support rod 401.
