Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foundry sand conveying, in particular to a lump sand conveying device for foundry. Background Art
[0002] Sand casting refers to a casting method that produces castings in sand molds. Since the molding materials used in sand casting are cheap and easy to obtain, the mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings, it has long been the basic process in casting production.
[0003] The basic raw materials for making sand molds are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. In order to make the sand mold and core have a certain strength and prevent deformation or damage during transportation, mold assembly and pouring of liquid metal, it is generally necessary to add sand binder during casting to bind the loose sand particles together to form sand; after the casting is poured, the sand mold needs to be separated from the casting, and the sand mold needs to be crushed and regenerated to reuse the sand.
[0004] At present, the sand conveying on the molding production line is generally carried out by pneumatic or belt conveying, but the sand particles cannot be too large. For lump sand, its fluidity is poor and pneumatic conveying cannot be used. Belt conveyor takes up a lot of space, and the foundry workshop is often compact in layout, so it is difficult to reserve extra space to install the belt conveyor. Utility Model Content
[0005] The present application provides a lump sand conveying device for casting to solve the technical problem of inconvenient lump sand conveying in the prior art.
[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme: a lump sand conveying device for casting, comprising a mounting frame, a sand storage is provided on the mounting frame, a guide rail is obliquely installed on one side of the mounting frame, and the upper end of the guide rail is located above the sand storage; a dump trolley is installed on the guide rail, and the dump trolley cooperates with the guide rail through the front wheels and the rear wheels, and the top part of the guide rail is forked to form an upper track and a lower track, and when the dump trolley moves to the top of the guide rail, the front wheel can move along the lower track and the rear wheel can move along the upper track.
[0007] When using this device for operation, lump sand can be added into the tipping trolley. When the tipping trolley moves along the guide rail to the fork, the front wheels move along the lower track and the rear wheels move along the upper track. Therefore, the tipping trolley will tip toward one side of the sand bin and pour the lump sand inside into the sand bin, thereby realizing the transportation of lump sand without taking up too much space.
[0008] Furthermore, the mounting frame includes an upper bracket and a lower bracket, and the sand storage is located on the top of the lower bracket.
[0009] Furthermore, the bottom of the upper bracket is fixed to the top of the lower bracket, a winch is fixed to the top of the upper bracket, and the winch is connected to the dump trolley through a wire rope; thus, the dump trolley can be easily lifted to the top of the guide rail by utilizing the traction force of the winch.
[0010] Furthermore, the dump truck comprises a portal frame and a truck bed, wherein the truck bed is installed in the portal frame and can be turned over relative to the portal frame.
[0011] Furthermore, the portal frame is connected to the bottom of the truck bucket via a rotating shaft; thereby, the truck bucket can have a larger turning angle, making it easier for the lump sand therein to enter the sand storage.
[0012] Furthermore, a rope pulley is installed on the top of the portal frame, and the rope pulley is connected to the steel wire rope.
[0013] Furthermore, the upper track is in an arc shape, and the center of the arc is the top of the lower track; thereby, when the front wheel moves to the top of the lower track, the truck bed will smoothly flip around the front wheel, while ensuring that the rear wheel always remains inside the arc-shaped upper track.
[0014] Furthermore, front wheels and rear wheels are installed on both sides of the dump truck. Correspondingly, two guide rails are provided, and the two guide rails respectively cooperate with the front wheels and rear wheels on both sides of the dump truck; thereby, the stability and stability of the dump truck during the movement along the guide rails can be improved.
[0015] Furthermore, a pit is provided on the ground on one side of the mounting frame, the lower end of the guide rail is located in the pit, and the width of the pit is greater than the width of the dump truck.
[0016] Furthermore, when the tipping trolley is located in the pit, the opening of the trolley bucket is flush with the upper edge of the pit; thereby, lumps of sand or sand grains can be loaded into the tipping trolley more conveniently.
[0017] It can be seen from the above technical solutions that the utility model has at least the following technical effects or advantages:
[0018] When using this device for operation, lump sand can be added into the tipping trolley. When the tipping trolley moves along the guide rail to the fork, the front wheels move along the lower track and the rear wheels move along the upper track. Therefore, the tipping trolley will tip toward one side of the sand bin and pour the lump sand inside into the sand bin, thereby realizing the transportation of lump sand without taking up too much space.

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the 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 described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0025] The utility model discloses a lump sand conveying device for casting, which comprises a mounting frame, on which a sand storehouse 6 is provided, a guide rail 4 is obliquely installed on one side of the mounting frame, and the upper end of the guide rail 4 is located above the sand storehouse 6; a dump trolley 2 is mounted on the guide rail 4, and the dump trolley 2 cooperates with the guide rail 4 through a front wheel 7 and a rear wheel 8, and when the dump trolley 2 moves along the guide rail 4, it can move to the top of the sand storehouse 6. In one example, the top portion of the guide rail 4 forks and forms two tracks of different heights, which are an upper track 402 and a lower track 401. When the dump trolley 2 moves to the top of the guide rail 4, the front wheel 7 can move along the lower track 401, and the rear wheel 8 can move along the upper track 402.
[0026] When using the device for operation, lump sand 1 can be added into the dump trolley 2. When the dump trolley 2 moves along the guide rail 4 to the fork, since the front wheel 7 moves along the lower track 401 and the rear wheel 8 moves along the upper track 402, the dump trolley 2 will tilt toward one side of the sand bin 6 and pour the lump sand 1 inside it into the sand bin 6.
[0027] The mounting frame is composed of two main parts: an upper support and a lower support. The sand storage 6 is arranged on the top of the lower support, and the bottom of the upper support is fixedly connected to the top of the lower support. A winch 5 is also installed on the top of the upper support, and the winch 5 is connected to the dump trolley 2 through a steel wire rope 3. Therefore, the dump trolley 2 can be easily lifted to the top of the guide rail 4 by the traction force of the winch 5.
[0028] In this embodiment, the dump truck 2 includes a portal frame 202 and a bucket 201. The bucket 201 is installed in the portal frame 202 and can be turned over relative to the portal frame 202. A rope pulley 9 is installed on the top of the portal frame 202, and the rope pulley 9 is connected to the wire rope 3. Therefore, during the process of the dump truck 2 being lifted along the guide rail 4, the portal frame 202 and the bucket 201 will move under the drive of the winch 5. When the front wheel 7 of the dump truck 2 moves to the top of the lower track 401, the portal frame 202 can still provide a force for the bucket 201, so that the rear wheel 8 moves along the upper track 402, and finally the dump truck 2 is turned over.
[0029] Preferably, if Figure 3 As shown, a rotating shaft 10 is installed at the bottom of the bucket 201, and both sides of the portal frame 202 are connected to the rotating shaft 10 at the bottom of the bucket 201. In this way, the bucket 201 can be turned around the rotating shaft 10 at the bottom relative to the portal frame 202, so that the bucket 201 can have a larger turning angle, which is convenient for the lump sand 1 therein to enter the sand storage 6.
[0030] On the other hand, the upper track 402 is in an arc shape, and the center of the arc is the top of the lower track 401. Therefore, when the front wheel 7 moves to the top of the lower track 401, the bucket 201 can smoothly flip around the front wheel 7, while ensuring that the rear wheel 8 always remains inside the arc-shaped upper track 402. Mechanical jamming and potential failure risks are reduced. In addition, the rear wheel 8 remains in the arc track, ensuring the stability and safety of the vehicle during the flipping process.
[0031] In this embodiment, front wheels 7 and rear wheels 8 are installed on both sides of the dump truck 2. Correspondingly, two guide rails 4 are also provided, which respectively cooperate with the front wheels 7 and rear wheels 8 on both sides of the dump truck, thereby keeping the dump truck 2 moving more stably on the guide rails 4.
[0032] In addition, a pit is provided on the ground on one side of the mounting frame, the purpose of which is to improve loading efficiency. Specifically in this embodiment, the lower end of the guide rail 4 is located in the pit, and the width of the pit is greater than the width of the dump truck 2, so that when the dump truck 2 is at the lowest position of the guide rail 4, the edge of the bucket 201 is flush with the upper edge of the pit, or the opening of the bucket 201 is lower than the upper edge of the pit. This simplifies the loading process of the lump sand 1 or sand particles, making the operation more convenient and quick.
