[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0034] It should be understood that the terms used herein are only for the purpose of describing specific example embodiments and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "include", "comprise", "contain", and "have" are inclusive, and therefore specify the existence of stated features, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not interpreted as necessarily requiring them to be performed in the specific order described or illustrated, unless the execution order is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0035] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0036] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is turned over, then the elements described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0037] Some sand cores are very heavy. For example, if a sand core weighs more than 100kg, it is difficult to transport the sand core to the core setting station (the core setting station is the preparation station for the sand core before it is placed in the sand mold for casting). It is necessary to use a crane, forklift or other transport tools to transport the sand core.

[0038] However, even if the sand core is transported by using a transport tool, it is necessary to manually transport the sand core to the transport tool.

[0039] Based on the above considerations, in order to solve the problem of how to conveniently transport sand cores and improve the efficiency of moving sand cores to the core lowering station, the utility model designs a sand core transfer auxiliary device, which includes a sand core body and a clamping device for clamping the sand core body, the clamping device is symmetrically provided with two clamping mechanisms for clamping the two end faces of the sand core body, and the clamping device also has a lifting part for cooperating with the lifting device to lift the sand core transfer auxiliary device as a whole, thereby realizing convenient transport of sand cores and improving the efficiency of moving sand cores to the core lowering station.

[0040] Figure 1 A schematic diagram of the structure of a sand core transport auxiliary device clamping a sand core body provided by an embodiment of the utility model; Figure 2 A schematic structural diagram of a sand core body of a sand core transport auxiliary device applicable to an embodiment of the utility model; Figure 3 A schematic diagram of the structure of a cross beam and a first longitudinal beam in a sand core transport auxiliary device provided in an embodiment of the utility model; Figure 4 A schematic diagram of the structure of the second longitudinal beam in the sand core transport auxiliary device provided in the embodiment of the utility model; Figure 1-Figure 4 The embodiment of the present application provides a sand core transport auxiliary device 10, the sand core includes a sand core body 1, and the two end faces 11 of the sand core body 1 are both provided with clamping holes 12. The sand core transport auxiliary device includes a clamping device 2 for clamping the sand core body 1, and the clamping device 2 includes: a cross beam 21, and the top of the cross beam is provided with a lifting portion 211; a first longitudinal beam 22, and the upper end of the first longitudinal beam 22 is fixedly connected to the first end of the cross beam 21; a second longitudinal beam 23, and the upper end of the second longitudinal beam 23 is connected to the first end of the cross beam 21 through a rotating pin 231. The second end of the cross beam 21 is rotatably connected so that the lower end of the second longitudinal beam 23 can move in the first direction toward or away from the first longitudinal beam 22; and two clamping mechanisms 24 are arranged at intervals along the first direction, and the two clamping mechanisms 24 are respectively arranged at the lower end of the first longitudinal beam 22 and the lower end of the second longitudinal beam 23, and the clamping mechanisms 24 are used to extend into the clamping hole 12 of the end face 11 of the sand core body 1, and each clamping mechanism 24 is arranged corresponding to the clamping hole 12 on one end face 11 of the sand core body 1.

[0041] Among them, reference Figure 2 The end surface 11 of the sand core body 1 is the surface at both ends of the sand core body 1 in its own length direction. The sand core body also includes an upper surface 13 and a lower surface 14.

[0042] In this embodiment, when the sand core needs to be transported, first, the clamping device 2 is placed next to the sand core body 1, and then the operator rotates the second longitudinal beam 23 relative to the cross beam 21 around the rotating pin 231, so that the lower end of the second longitudinal beam 23 moves in the first direction away from the first longitudinal beam 22 to make room for the sand core body 1; then the position of the clamping device 2 is adjusted so that the sand core body 1 is below the cross beam 21 of the clamping device 2, between the first longitudinal beam 22 and the second longitudinal beam 23, and the two end faces of the sand core body 1 are close to the first longitudinal beam 22 and the second longitudinal beam 23 respectively; then the clamping mechanism 2 at the lower end of the first longitudinal beam 22 is adjusted. 4 is inserted into the clamping hole 12 on the end surface of the sand core body 1 close to the first longitudinal beam 22, and then the second longitudinal beam 23 is rotated relative to the cross beam 21 around the rotating pin 231, so that the lower end of the second longitudinal beam 23 moves in the first direction toward the direction close to the first longitudinal beam 22, until the clamping mechanism 24 at the lower end of the second longitudinal beam 23 is inserted into the clamping hole 12 on the end surface of the sand core body 1 close to the second longitudinal beam 23, and the sand core body 1 is clamped by the clamping device 2 at this time; finally, the lifting device is connected to the lifting part 211 on the top of the cross beam 21, and the clamping device 2 is lifted together with the sand core body 1 and placed on the traveling crane, so that the sand core can be transported.

[0043] Therefore, the sand core transfer auxiliary device 10 provided in this embodiment can realize the convenient transportation of sand cores and improve the efficiency of moving the sand cores to the core setting station; in addition, continuing to operate the lifting device to move the clamping device 2 together with the sand core body 1 down into the sand mold can also conveniently and accurately realize the core setting of the sand core, further improving the casting efficiency.

[0044] refer to Figure 4 According to an optional embodiment of the present application, the upper end of the second longitudinal beam 23 has a limiting groove 232, and the clamping device 2 also includes a limiting mechanism, which has a limiting protrusion 2521. The limiting protrusion 2521 is used to engage with the limiting groove 232 to limit the rotation of the second longitudinal beam 23 relative to the cross beam 21.

[0045] In this embodiment, when it is necessary to adjust the position of the limiting mechanism installed at the lower end of the second longitudinal beam 23, the limiting protrusion 2521 is removed from the limiting groove 232 to release the clamping relationship between the two, so that the second longitudinal beam 23 can rotate relative to the cross beam 21 around the rotating pin 231 to adjust the position of the limiting mechanism installed at the lower end of the second longitudinal beam 23; when the two end faces of the sand core body 1 are clamped by the clamping mechanism 24, the limiting protrusion 2521 is clamped and matched with the limiting groove 232. At this time, the second longitudinal beam 23 cannot rotate relative to the cross beam 21, that is, the sand core body 1 is "locked", thereby ensuring that the limiting mechanism installed at the lower end of the second cross beam 21 can stably penetrate into the clamping hole 12 on the end face of the sand core body 1 close to the second longitudinal beam 23, thereby preventing the sand core from falling due to the loose clamping of the sand core body 1 by the clamping device 2 when the sand core transport auxiliary device 10 is lifted or transported.

[0046] Therefore, the configuration of this embodiment can improve the stability of the clamping device 2 on the sand core body 1, thereby reducing the risk of the sand core body 1 falling during transportation.

[0047] Figure 5 The schematic diagram of the structure of the limit rod in the sand core transport auxiliary device provided by the embodiment of the utility model is shown in FIG. Figure 1 , Figure 3 , Figure 4 and Figure 5 According to an optional embodiment of the present application, the limiting mechanism includes a limiting rod 25, the limiting rod 25 includes a connecting rod 251 and a limiting portion 252 arranged at one end of the connecting rod 251, the limiting portion 252 is rotatably connected to the second end of the beam 21 through a limiting pin 253, the extension direction of the limiting pin 253 is the same as the extension direction of the rotating pin 231, and the limiting protrusion 2521 is arranged on the limiting portion 252.

[0048] When the clamping device 2 has completed clamping the two end faces of the sand core, the connecting rod 251 is pressed downward to drive the limiting part 252 to rotate clockwise around the limiting pin 253 until the limiting protrusion 2521 on the limiting part 252 is engaged with the limiting groove 2431 at the upper end of the second longitudinal beam 23. At this time, the second longitudinal beam 23 cannot rotate relative to the cross beam 21, thus achieving the "locking" of the sand core body 1.

[0049] Therefore, the setting of the limiting rod 25 has a simple structure and is easy to install, and can well ensure the stability of the sand core transport auxiliary device 10 during the lifting or transport process.

[0050] like Figure 1 As shown, according to an optional embodiment of the present application, the clamping mechanism 24 includes a clamping member 241 for extending into the clamping hole 12 , and an extending direction of the clamping member 241 is the same as an extending direction of the clamping hole 12 .

[0051] In this embodiment, the clamping member 241 can be a columnar, rod-shaped, cylindrical or other structure, and its function is to penetrate into the clamping hole 12 of the sand core body 1 and fit tightly with the inner wall of the clamping hole 12. When the sand core body 1 is lifted along with the clamping device 2, the clamping member 241 can support the clamping hole 12, thereby achieving support for the entire sand core body 1.

[0052] like Figure 1 and Figure 2 As shown, according to an optional embodiment of the present application, the two end faces of the sand core body 1 are provided with a plurality of clamping holes 12, and the number of clamping members 241 of the clamping mechanism 24 is multiple; in a group of corresponding clamping mechanisms 24 and end faces of the sand core body 1: the number of clamping members 241 is the same as the number of clamping holes 12, and the clamping members 241 and the clamping holes 12 are arranged one by one.

[0053] In this embodiment, it is taken as an example that each end surface of the sand core body 1 is provided with three clamping holes 12. Figure 2 As shown; the number of clamping members 241 of the clamping mechanism 24 corresponding to each end face is also three, and the three-point support method is relatively stable. When the clamping device 2 clamps the sand core body 1 and the two are lifted or transported together, the sand core body 1 can be more stable.

[0054] Specifically, the center lines of the three clamping holes 12 can form an equilateral triangle to provide a more stable support, further preventing the sand core from falling due to the loose clamping of the sand core body 1 by the clamping device 2 when the sand core transport auxiliary device 10 is lifted or transported.

[0055] refer to Figure 1According to an optional embodiment of the present application, the clamping mechanism 24 also includes a rotating shaft 242; in a group of rotating shafts 242 and multiple clamping members 241 that cooperate with each other: the extension direction of the rotating shaft 242 is the same as the extension direction of the clamping member 241, the rotating shaft 242 is fixedly connected to the multiple clamping members 241, and the multiple clamping members 241 can make circular motion with the rotating shaft 242 as the rotating shaft 242; the rotating shafts 242 of the two clamping mechanisms 24 rotate simultaneously to drive the sand core body 1 to rotate 180°; the lower end of the first longitudinal beam 22 is provided with a first mounting hole 221 for mounting a rotating shaft 242, and the lower end of the second longitudinal beam 23 is provided with a second mounting hole 233 for mounting another rotating shaft 242.

[0056] Because some sand cores need to be rotated 180° before casting, the clamping mechanism 24 of this embodiment is provided with a rotating shaft 242, and each clamping mechanism 24 is provided with a plurality of clamping members 241 to achieve 180° rotation of the sand core body 1.

[0057] Specifically, in this embodiment, after the sand core body 1 is transferred to the core setting station by the clamping device 2, the rotating shafts 242 of the two clamping mechanisms 24 are rotated at the same time. Since the rotating shafts 242 are fixedly connected to the multiple clamping members 241, the multiple clamping members 241 of each clamping mechanism 24 can make circular motion with the rotating shaft 242 as the rotating shaft 242, thereby driving the sand core body 1 to rotate. After the sand core body 1 rotates 180°, the rotating shaft 242 stops rotating. At this time, the sand core body 1 is adjusted to the position before the core is set.

[0058] Therefore, the setting of the rotating shaft 242 in the present embodiment can be applicable to the sand core body 1 with different core lowering directions, thereby increasing the application scenarios of the sand core transport auxiliary device 10.

[0059] Continue to refer Figure 1 According to an optional embodiment of the present application, the clamping mechanism 24 also includes a clamping plate 243, which is used to clamp the end face of the sand core body 1; in a group of corresponding clamping plates 243 and rotating shafts 242: one side of the clamping plate 243 is fixedly connected to the rotating shaft 242, and a plurality of clamping members 241 are arranged on the side of the clamping plate 243 away from the rotating shaft 242.

[0060] In this embodiment, the clamping plate 243 is provided so that when the clamping member 241 extends into the clamping hole 12 , the clamping plate 243 can clamp the end surface of the sand core body 1 , thereby further clamping the sand core body 1 and improving the stability of the sand core body 1 .

[0061] In addition, if Figure 1As shown, the clamping mechanism 24 may further include a pad 244, which is used to protect the end face of the sand core body 1; in a set of corresponding clamping plates 243, pads 244 and rotating shaft 242: the pad 244 is arranged on the side of the clamping plate 243 away from the rotating shaft 242. The pad 244 may be made of a relatively soft material, such as rubber, and the rubber pad 244 can protect the end face of the sand core body 1 while also increasing friction, thereby improving the clamping effect.

[0062] like Figure 1 As shown, according to an optional embodiment of the present application, a positioning pin 222 is provided on the first longitudinal beam 22; for the clamping mechanism 24 arranged on the first longitudinal beam 22: a clamping plate 243 of the clamping mechanism 24 is provided with a slot 2431 for engaging with the positioning pin 222, and when the positioning pin 222 is inserted into the slot 2431, the sand core body 1 is in the core lowering position.

[0063] The positioning pin 222 can be connected to the first longitudinal beam 22 via the positioning shaft 223, and the extending direction of the positioning shaft 223 is perpendicular to the extending direction of the first longitudinal beam 22. When the positioning pin 222 can be inserted into the slot 2431, it indicates that the sand core body 1 is in the core setting position; therefore, for the sand core body 1 that needs to be rotated 180° to set the core, the slot 2431 should be installed at one end of the clamping plate 243 close to the lower surface 14 of the sand core body 1, such as Figure 1 As shown, the positioning pin 222 can be locked into or out of the locking slot 2431 by rotating around the positioning shaft 223 .

[0064] In this embodiment, the arrangement of the positioning pin 222 and the clamping groove 2431 can make the core setting of the sand core body 1 more accurate, thereby ensuring the quality of the final casting.

[0065] refer to Figure 1 According to an optional embodiment of the present application, the clamping mechanism 24 also includes a handle 245; in a set of corresponding handles 245 and rotating shafts 242: the handle 245 is fixedly connected to the rotating shaft 242.

[0066] In this embodiment, the setting of the handle 245 makes it easier for the operator to rotate the shaft 242, thereby improving work efficiency. In addition, the size of the handle 245 can be set larger to increase the rotation force arm, thereby saving effort.

[0067] An embodiment of the present application also provides a sand core transfer system, including any one of the above-mentioned sand core transfer auxiliary devices 10, and the sand core transfer system also includes: a lifting device for connecting to a lifting part 211, the lifting device being capable of lifting the sand core transfer auxiliary device 10; and a crane for transporting the sand core transfer auxiliary device 10.

[0068] The beneficial effects of the sand core transfer system provided in this embodiment are the same as those of any of the above-mentioned sand core transfer auxiliary devices 10 , and will not be described in detail.

[0069] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
