Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and in particular to a metal casting transport vehicle. Background Technology

[0002] Metal casting is a process in which metal is melted into a liquid that meets certain requirements and poured into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size, and properties is obtained. The handling of molten iron in metal casting is an important part of the metal casting industry.

[0003] Currently, some small businesses still rely on manual handling or make simple handling vehicles to reduce their burden. For example, document CN205996187U discloses a low-cost molten iron casting vehicle for casting grinding balls. It adopts a two-wheel drive wheel design. During the handling of molten iron, it lacks an effective closed structure, and the molten iron is prone to splashing due to bumps or vibrations. Furthermore, the casting process involves directly controlling the rotation of the shaft manually, which can easily lead to accidental tipping due to the weight of the molten iron or accidental contact, posing a significant safety risk. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a metal casting transport vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal casting transport vehicle includes a vehicle body and a casting barrel. The vehicle body includes a long pipe and a short pipe arranged perpendicularly to each other and fixedly connected. Drive wheels are installed at both ends of the short pipe. A rotating shaft is rotatably installed inside the long pipe. The casting barrel is fixedly installed on one end of the rotating shaft. A pressure cap is hinged to one end of the long pipe and can cover the casting barrel. A control box is fixedly connected to the other end of the long pipe. An opening and closing control mechanism and a rotation control mechanism are respectively installed in the control box. The opening and closing control mechanism drives the pressure cap to rotate to cover and open the casting barrel. The rotation control mechanism drives the rotating shaft to rotate, so that the casting barrel is tilted to pour molten iron.

[0007] Preferably, the opening and closing control mechanism includes a first rocker arm and a transverse rotating rod rotatably mounted on the control box. A first gear is fixedly sleeved on the first rocker arm, and a second gear, a winding wheel, and a ratchet are sequentially fixedly sleeved on the transverse rotating rod. The second gear and the first gear mesh with each other. A pull rope is fixedly connected to the winding wheel, and the end of the pull rope away from the winding wheel is fixedly connected to the pressure cap.

[0008] Preferably, the control box has a limit rod that engages with a ratchet via a pivot pin. A spring is fixedly connected between the limit rod and the control box. A lever is fixedly connected to the side of the limit rod. The control box has a slot. The end of the lever away from the limit rod passes through the slot and extends outside the control box.

[0009] Preferably, the rotation control mechanism includes a second rocker arm and a vertical rotating rod rotatably mounted on the control box. One end of the rotating shaft extends into the control box and is fixedly sleeved with a worm gear. The bottom end of the vertical rotating rod is fixedly connected to a worm gear that meshes with the worm gear. A driving wheel and a driven wheel are respectively fixedly sleeved on the second rocker arm and the vertical rotating rod. A transmission belt is provided between the driving wheel and the driven wheel for transmission.

[0010] Preferably, the number of teeth of the first gear is twice the number of teeth of the second gear, and the diameter of the driving gear is twice the diameter of the driven gear.

[0011] Preferably, a number of guide wheels are fixedly installed on the long tube, and the number of guide wheels is at least two and they are in contact with the pull rope.

[0012] Preferably, two limiting blocks are fixedly connected to the long tube, and an elastic pad is fixedly connected to each of the two limiting blocks. When the pressure cap is opened and closed, it contacts the elastic pads on the two limiting blocks respectively, and the included angle between the two limiting blocks is 70°.

[0013] Preferably, a support base is fixedly connected to the long tube, and a handle is fixedly connected to the end of the long tube that connects to the control box.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this application, through the opening and closing control mechanism and the rotation control mechanism, the operator can easily realize the opening and closing of the cap and the tilting and resetting of the casting barrel through the two mechanisms. It is easy to use and suitable for small and medium-sized enterprises.

[0016] 2. In this application, the cover can seal the casting ladle to a certain extent during the handling of molten iron, effectively reducing the risk of molten iron splashing, thereby reducing safety hazards and ensuring the safety of operators.

[0017] 3. In this application, a worm gear transmission is used to control the tilt angle of the casting barrel. The self-locking characteristic of the worm gear prevents the casting barrel from tilting accidentally due to the weight of the molten iron or operator misoperation, thus ensuring the stability and safety of the handling and casting process.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1-5As shown, this utility model provides a metal casting transport vehicle, including a vehicle body 200 and a casting barrel 100. The vehicle body 200 includes a long pipe 201 and a short pipe 202 that are perpendicularly arranged and fixedly connected to each other. Drive wheels 203 are installed at both ends of the short pipe 202. A rotating shaft 300 is rotatably arranged inside the long pipe 201. The casting barrel 100 is fixedly installed on one end of the rotating shaft 300. A pressure cap 400 is hinged to one end of the long pipe 201. The pressure cap 400 can cover the casting barrel 100. A control box 500 is fixedly connected to the other end of the long pipe 201. An opening and closing control mechanism 600 and a rotation control mechanism 700 are respectively installed in the control box 500. The opening and closing control mechanism 600 drives the pressure cap 400 to rotate to cover and open the casting barrel 100. The rotation control mechanism 700 drives the rotating shaft 300 to rotate so that the casting barrel 100 is tilted to pour molten iron.

[0028] In this embodiment, the opening and closing control mechanism 600 includes a first rocker arm 601 and a transverse rotating rod 602 rotatably mounted on the control box 500. A first gear 603 is fixedly sleeved on the first rocker arm 601. A second gear 604, a winding wheel 605, and a ratchet 606 are sequentially fixedly sleeved on the transverse rotating rod 602. The second gear 604 and the first gear 603 mesh with each other. A pull rope 607 is fixedly connected to the winding wheel 605. One end of the pull rope 607 away from the winding wheel 605 is fixedly connected to the pressure cover 400.

[0029] Specifically, the first rocker arm 601 rotates to make the first gear 603 rotate, and the second gear 604 that cooperates with it drives the transverse rotating rod 602 to rotate, so that the winding wheel 605 tightens the pull rope 607, and the pull rope 607 pulls the pressure cover 400 to rotate and open, so that the pressure cover 400 can be easily opened when adding molten iron and pouring molten iron.

[0030] In this embodiment, a limiting rod 608 that engages with a ratchet 606 is hinged to the control box 500 via a pivot pin. A spring 609 is fixedly connected between the limiting rod 608 and the control box 500. A lever 610 is fixedly connected to the side of the limiting rod 608. A barrel groove 501 is provided on the control box 500. The end of the lever 610 away from the limiting rod 608 passes through the barrel groove 501 and extends to the outside of the control box 500.

[0031] Specifically, during the process of the take-up wheel 605 tightening the pull rope 607, the transverse rotating rod 602 also drives the ratchet 606 to rotate. The ratchet 606 engages with the limit rod 608 to limit the rotation and prevent reverse rotation, thus avoiding sudden closure of the cover 400 during opening. When closing the cover 400, the first rocker arm 601 is finely adjusted and the lever 610 is pushed. The lever 610 causes the limit rod 608 to disengage from the ratchet 606 and the spring 609 to contract. The pull rope 607 is relaxed and the cover 400 closes due to gravity.

[0032] In this embodiment, the rotation control mechanism 700 includes a second rocker arm 701 and a vertical rotating rod 702 rotatably mounted on the control box 500. One end of the rotating shaft 300 extends into the control box and is fixedly sleeved with a worm gear 703. The bottom end of the vertical rotating rod 702 is fixedly connected to a worm 704 that meshes with the worm gear 703. A driving wheel 705 and a driven wheel 706 are respectively fixedly sleeved on the second rocker arm 701 and the vertical rotating rod 702. A transmission belt 707 is provided between the driving wheel 705 and the driven wheel 706 for transmission.

[0033] Specifically, the rotation of the second rocker arm 701 causes the driving wheel 705 to drive the driven wheel 706 to rotate via the transmission belt 707, which in turn drives the vertical rotating rod 702 to rotate. The worm gear 704 follows the rotation and drives the worm wheel 703 to rotate, thereby driving the rotating shaft 300 to rotate and tilt the casting bucket 100 to pour out the molten iron. Reversing the second rocker arm 701 can reset the casting bucket 100. The worm wheel 703 is used and its self-locking characteristic prevents the molten iron from accidentally tipping over due to its own weight.

[0034] In this embodiment, the number of teeth of the first gear 603 is twice the number of teeth of the second gear 604, and the diameter of the driving gear 705 is twice the diameter of the driven gear 706.

[0035] Specifically, since the diameter of the driving wheel 705 is twice the diameter of the driven wheel 706, the operator needs relatively little force to crank the second rocker arm 701 to achieve the rotation of the rotating shaft 300; since the number of teeth of the first gear 603 is twice the number of teeth of the second gear 604, the increased speed of the second gear 604 can make the winding wheel 605 rotate quickly, thereby increasing the opening speed of the pressure cap 400.

[0036] In this embodiment, a number of guide wheels 611 are fixedly installed on the long tube 201. The number of guide wheels 611 is at least two and they are in contact with the pull rope 607.

[0037] Specifically, the guide wheel 611 guides the pull rope 607, thus limiting the pull rope 607 during the pulling and releasing process, which is a reasonable design.

[0038] In this embodiment, two limiting blocks 800 are fixedly connected to the long tube 201, and elastic pads 801 are fixedly connected to both limiting blocks 801. When the pressure cap 400 is opened and closed, it contacts the elastic pads 801 on the two limiting blocks 800 respectively, and the included angle between the two limiting blocks 800 is 70°.

[0039] When the cap 400 is opened and closed, it will contact the elastic pad 801 on the limit block 800, which can play a buffering and protective role. Due to the setting of the two limit blocks 800, the opening and closing angle of the cap 400 is limited to 70°, which can completely not block the casting barrel 100, and the cap 400 can close due to its own gravity after the pull rope 607 is relaxed.

[0040] In this embodiment, a support base 204 is fixedly connected to the long tube 201, and a handle 205 is fixedly connected to the end of the long tube 201 that is connected to the control box 500.

[0041] Specifically, when the vehicle body 200 is stationary, the support seat 204 contacts the ground, forming a three-point support to stabilize the support, and the handle 205 makes pushing easier.

[0042] How to use and how to work this device:

[0043] When in use, the operator pushes the vehicle body 200 with the handle 205. The drive wheel 203 and the support seat 204 touch the ground to form a three-point support, ensuring the stability of the vehicle body 200. Rotating the first rocker arm 601 rotates the first gear 603, and the second gear 604 that cooperates with it drives the transverse rotating rod 602 to rotate, so that the winding wheel 605 tightens the pull rope 607. The pull rope 607 pulls the pressure cover 400 to rotate and open. The ratchet 606 engages with the limit rod 608 to keep the pressure cover 400 in the open state, so that molten iron can be poured into the casting bucket 100.

[0044] Subsequently, the limit rod 608 is disengaged from the ratchet 606 by the lever 610 and the spring 609 is contracted. The pull rope 607 is relaxed and the pressure cover 400 is closed by gravity. The worker drives the vehicle 200 to the casting site. During this process, the pressure cover 400 seals the casting barrel 100 to a certain extent, which can reduce the risk of molten iron splashing and thus reduce safety hazards.

[0045] After the worker drives the vehicle 200 to the casting site, he repeats the above operation to open the pressure cover 400. Then, he rotates the second rocker arm 701 to make the drive wheel 705 drive the driven wheel 706 to rotate through the transmission belt 707, which in turn drives the vertical rotating rod 702 to rotate. The worm 704 follows the rotation and drives the worm wheel 703 to rotate, thereby driving the rotating shaft 300 to rotate and tilting the casting bucket 100 to pour out the molten iron. The self-locking characteristics of the worm wheel 703 and worm 704 prevent accidental tipping caused by the weight of the molten iron or by the operator's accidental contact.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
