DETAILED DESCRIPTION

[0034] The technical solutions of the utility model will be described clearly and completely below in combination with embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] As Figures 1-7 shown, one embodiment of the utility model provides a kind of alloy sampling pouring device, including trolley 1, lifting arm connecting rod mechanism, guide rail mechanism, iron barrel bracket 7, receiving hopper 9 and telescopic drive piece;The platform of trolley 1 is provided with mounting hole, receiving hopper 9 is located in mounting hole;

[0036] The guide rail mechanism comprises at least one guide rail 8, which comprises a vertical rail and an arc rail 801 connected to each other, the vertical rail is vertically installed on the side of the trolley 1, the arc rail 801 is higher than the table top of the trolley 1, and the end of the arc rail 801 points to the receiving hopper 9, the iron bucket bracket 7 is slidably installed on the guide rail 8, and the iron bucket bracket 7 is used for carrying the iron bucket containing the alloy;

[0037] The first end of the boom linkage mechanism is hingedly connected to the table top of the trolley 1, and the other end is hingedly connected to the iron bucket bracket 7; the first end of the telescopic driving member is hingedly connected to the trolley 1, and the other end is hingedly connected to the boom linkage mechanism; the telescopic driving member is used for driving the boom linkage mechanism to pull the iron bucket bracket 7 to slide along the guide rail 8.

[0038] In the embodiment, when the noble metal alloy in the iron bucket is sampled or taken, an empty bucket is placed under the trolley 1 located below the receiving hopper 9, then the iron bucket is carried to the iron bucket bracket 7, and then the hydraulic cylinder 10 is started, the hydraulic cylinder 10 is elongated to drive the boom linkage mechanism to pull the iron bucket bracket 7 to move upwards along the guide rail 8, when the iron bucket bracket 7 moves to the arc rail 801, the iron bucket on the iron bucket bracket 7 is gradually tilted, so that the noble metal alloy in the iron bucket is poured into the receiving hopper 9.

[0039] In this way, the noble metal alloy in the iron bucket can be simply and quickly poured out, without the cooperation of the crown block, and without the cooperation of multiple people, so that the labor intensity is small, the safety factor is high, the crown block and other human resources are released, and even when the crown block is busy or fails, the sampling or taking work is not affected.

[0040] In the embodiment, as shown in the drawings, Figure 1 The boom linkage mechanism comprises a linkage 3, a boom 4, an adapter plate 5 and a pull rod 6 connected in sequence, two hinge shaft seats 2 are fixedly installed on the table top of the trolley 1, a first pin shaft is rotatably installed between the two hinge shaft seats 2, and one end of the linkage 3 away from the boom 4 is fixedly connected to the first pin shaft. An included angle formed between the boom 4 and the linkage 3 is obtuse, a cavity is arranged in the trolley 1, a bottom end of the hydraulic cylinder 10 is hingedly connected to a mounting seat on the bottom wall in the cavity, and the other end of the hydraulic cylinder 10 is hingedly connected to a second pin shaft on one end of the linkage 3 close to the boom 4. The adapter plate 5 is connected to one end of the boom 4 away from the linkage 3, the adapter plate 5 has a first end and a second end, the first end of the adapter plate 5 is fixedly connected to one end of the boom 4 away from the linkage 3, the second end of the adapter plate 5 points to the ground, a third pin shaft is arranged between the first end of the pull rod 6 and the second end of the adapter plate 5, and the second end of the pull rod 6 is hingedly connected to the iron bucket bracket 7.

[0041] During sampling, the worker places the iron drum containing the precious metal alloy onto the iron drum holder 7, and then activates the hydraulic cylinder 10. The hydraulic cylinder 10 extends to push the connecting rod 3 to rotate clockwise around the first pin. Driven by the connecting rod 3, the pull rod 6 pulls the iron drum holder 7 to slide upward along the guide rail 8 until the iron drum holder 7 moves onto the arc-shaped rail 801. At this point, the iron drum on the iron drum holder 7 gradually tilts, thus pouring the precious metal alloy inside the iron drum into the receiving hopper 9.

[0042] As a specific embodiment, such as Figure 2 As shown, there are two of each of the following: boom 4, adapter plate 5, and tie rod 6, with each boom 4, adapter plate 5, and tie rod 6 corresponding to the other. The first end of each boom 4 is simultaneously connected to one end of the connecting rod 3. An adapter plate 5 is fixedly installed on the second end of each boom 4, and a connecting rod 501 is fixedly installed between the two adapter plates 5, forming a triangular frame structure between the connecting rod 501 and the two booms 4. The first end of each tie rod 6 is hinged to the second end of each adapter plate 5 via a third pin, and the second end of each tie rod 6 is hinged to both sides of the iron barrel bracket 7 via a fourth pin 11.

[0043] It is important to understand that the triangular structure formed between the connecting rod 501 and the two booms 4 can greatly improve the structural strength of this boom linkage mechanism, enabling it to stably lift heavy iron drums containing alloys. Furthermore, the use of two tie rods 6 to connect the iron drum bracket 7 allows for more stable pulling of the iron drum bracket 7.

[0044] In this embodiment, the guide rail mechanism includes two guide rails 8, which are vertically fixed to the same side of the trolley 1. The iron barrel bracket 7 is slidably installed between the two guide rails 8. This arrangement ensures the stability of the iron barrel bracket 7 when sliding on the guide rails 8 and effectively prevents the two from separating.

[0045] It should be noted that there are various ways to slide between the guide rail 8 and the iron bucket bracket 7. For example, a slider can be slidably installed on the guide rail 8, and then the two sides of the iron bucket bracket 7 can be fixedly connected to the two guide rails 8 respectively. Another example is that multiple rollers can be installed on the sides of the iron bucket bracket 7, and multiple roller grooves adapted to the rollers can be opened on the guide rail 8. The rollers on both sides of the iron bucket bracket 7 can be embedded into the roller grooves on the two guide rails 8 and can slide along the roller grooves. These are just a few examples; any method that allows the iron bucket bracket 7 to slide along the guide rail 8 is acceptable.

[0046] To prevent the iron drum support 7 from separating from the arc-shaped rail 801 when it moves to the top of the arc-shaped rail 801 of the guide rail 8, a stop block is fixed at the top of the arc-shaped rail 801 to block the iron drum support 7.

[0047] As a preferred embodiment, in order to ensure the flexibility of the alloy sampling pouring device, the four corners of the trolley 1 are provided with rollers 101. It should be noted that, as shown in the drawings, the two rollers 101 on the left side of the trolley 1 are metal rollers, and the two rollers 101 on the left side are a double wheel pair. The double wheel pair is composed of two wheels which can be coaxial or independent but synchronous. The double wheel pair is a metal roller. The two rollers 101 on the right side of the trolley 1 are universal wheels. Figure 1

[0048] It should be noted that when the iron bucket is lifted, the weight of the whole bucket of alloy is mainly borne by the front wheels, that is, the rollers 101 on the left side of the trolley 1, so the rollers 101 on the left side of the trolley 1 are set as a double wheel pair to improve stability and carrying capacity. Moreover, the metal roller will not easily embed into metal iron filings or hard particles like polyurethane rubber wheels, and has stronger carrying capacity, better adaptability to the working environment and longer service life. Figure 1

[0049] In this embodiment, as shown in the drawings, the iron bucket bracket 7 includes two side plates 701, two side rods 703, a connecting bottom plate 702, a cross beam 704, an arc-shaped seat 705, a plurality of ear plates 706 and at least one bucket mouth clamp. The two side rods 703 are respectively fixed at the bottom of the two side plates 701, the connecting bottom plate 702 is fixed between the two side rods 703, the cross beam 704 is fixed between the sides of the two side plates 701 near the top thereof, the arc-shaped seat 705 is welded on the cross beam 704, and an arc-shaped surface for fitting the iron bucket is formed on the arc-shaped seat 705. A plurality of ear plates 706 for blocking the mouth of the iron bucket are welded on the arc-shaped surface, and the ear plates 706 are used to block the iron bucket when the iron bucket is in an inclined state to prevent the iron bucket from falling off the iron bucket bracket 7. The bucket mouth clamp is fixedly installed on the arc-shaped seat 705 (not shown in the drawings). Figure 3

[0050] It should be noted that in this embodiment, an arc-shaped groove is formed on the top surface of the connecting bottom plate 702, which is used to fit the side surface of the iron bucket.

[0051] In this embodiment, the bucket mouth clamp, as shown in the drawings, includes a chain 14, a connecting ring 15, a main hook 12 and a locking hook 13; one end of the chain 14 is welded to the top surface of the arc-shaped seat 705, and the other end is hingedly connected to the first end of the connecting ring 15 through a hook ring pin 16. The main hook 12 includes an arc-shaped hook 121 and an L-shaped hook 122 connected to each other, the left end of the arc-shaped hook 121 forms a first hook tip 123, the other end is connected to the top end of the L-shaped hook 122, the end of the L-shaped hook 122 away from the arc-shaped hook 121 forms an abutting end 124, the abutting end 124 faces the first hook tip 123, and the abutting end 124 is lower than the first hook tip 123. Figure 5 Figure 6

[0052] ​​​​​The arc-shaped hook 121 forms a semi-enclosed locking cavity inside. The horizontal distance between the abutting end 124 and the first hook tip 123 is greater than the wall thickness of the iron drum, so that the mouth of the iron drum extends into the locking cavity. The main hook 12 is provided with a mounting hole for inserting the locking hook 13, and the mounting hole is formed from the top of the main hook 12 towards the bottom.

[0053] Further, the locking hook 13 comprises a handle 132 and a hook head 131 connected together. The hook head 131 is in the shape of a bent hook. A first mounting hole is formed at the end of the handle 132 close to the hook head 131. A second mounting hole is formed in the arc-shaped hook 121 and communicates with the first mounting hole. The entire hook head 131 of the locking hook 13 and the end of the handle 132 close to the hook head 131 extend into the mounting hole of the main hook 12, and the first mounting hole of the locking hook 13 is aligned with the second mounting hole of the arc-shaped hook 121.

[0054] Further, the locking hook 13 and the arc-shaped hook 121 are hingedly connected through a hook pin 17 and a return spring 18. Specifically, the return spring 18 is provided with a bushing in the center hole. The return spring 18 is sleeved on the hook pin 17 through the bushing, and the hook pin 17 is installed in the first mounting hole and the second mounting hole.

[0055] Further, the end of the hook head 131 away from the handle 132 forms a second hook tip 133. The second hook tip 133 extends into the locking cavity, or in other words, the projection of the second hook tip 133 falls into the locking cavity in the direction perpendicular to the paper surface. Figure 6 In addition, the second end of the connecting ring 15 is connected to the handle 132, and the connecting ring 15 functions as a connecting member.

[0056] In this embodiment, when the alloy sampling and pouring device is used, the trolley 1 is first pushed to be close to the iron drum, so that the side surface of the iron drum is fitted to the inner wall of the arc-shaped groove of the connecting bottom plate 702. Then, the hydraulic cylinder 10 is controlled to shorten a certain length, so as to pull the iron drum carrier 7 to descend by a certain height, and then the mouth clamp also descends by a certain height. During the descending process of the mouth clamp, the Figure 5As shown, the abutting end 124 is attached to the outer wall of the iron drum, the barrel mouth of the iron drum extends into the locking cavity of the arc-shaped hook 121, and at this time, the first hook tip 123 of the arc-shaped hook 121 is attached to the inner wall of the barrel mouth, and the second hook tip 133 of the locking hook 13 is located outside the barrel mouth. Then the worker can manually push the handle 132 clockwise to make the second hook tip 133 of the locking hook 13 hook on the ring rib on the outer side of the barrel mouth of the iron drum. Then the hydraulic cylinder 10 is elongated by a certain length to pull the iron drum carrier 7 upwards, because the top end of the chain 14 is welded on the arc-shaped seat 705, so the chain 14 pulls the handle 132, the handle 132 rotates clockwise around the axis of the hook pin 17, and the second hook tip 133 of the locking hook 13 rotates towards the first hook tip 123 to clamp the barrel mouth together with the first hook tip 123. Moreover, as the iron drum is gradually pulled up, the greater the pulling force on the locking hook 13, the greater the pressure on the outer wall of the barrel mouth by the second hook tip 133 of the locking hook 13, so that the barrel mouth can be clamped firmly.

[0057] It should be noted that, as shown in the drawings, Figure 5 The outer wall of the barrel mouth of the iron drum is generally provided with a ring rib or a convex rib, and when the barrel mouth clamp clamps the barrel mouth, the second hook tip 133 of the locking hook 13 hooks on the ring rib on the outer side of the barrel mouth of the iron drum, so that the gravity of the iron drum acts on the second hook tip 133 of the locking hook 13.

[0058] After the material is taken out, the iron drum is placed on the ground, and the handle 132 is in a force-free state, at this time, the handle 132 can be rotated counterclockwise by a certain angle to make the second hook tip 133 of the locking hook 13 separate from the outer wall of the barrel mouth, so that the barrel mouth clamp and the iron drum are separated.

[0059] The special structure of the barrel mouth clamp in the embodiment can firmly clamp the barrel mouth of the iron drum to ensure that the iron drum does not fall off during pouring, and ensures the safety of the equipment. The chain 14, the locking hook 13 and the main hook 12 of the barrel mouth clamp are all made of alloy, which has high strength and long service life.

[0060] It should be noted that the installation position and the number of the barrel mouth clamp are not limited, the barrel mouth clamp can be installed on the arc surface of the arc-shaped seat 705 or on the side surface of the arc-shaped seat 705. Of course, it can also not be installed on the arc-shaped seat 705, but on the cross beam 704 of the iron drum carrier 7.

[0061] It should be noted that when the worker manually rotates the locking hook 13, one hand usually holds the main hook 12 still, and the other hand holds the handle 132 and rotates the handle 132, so that the second hook tip 133 of the locking hook 13 approaches or moves away from the first hook tip 123. It is more laborious to use.

[0062] In order to solve this problem, as shown in the drawings, Figure 7As shown, a force assisting rod 125 is integrally formed or welded on the side of the arc-shaped hook 121 of the main hook 12, and the force assisting rod 125 is located on the side of the first hook tip 123, and the force assisting rod 125 is obliquely arranged. The included angle between the length direction of the force assisting rod 125 and the handle 132 is obtuse.

[0063] Thus, when the rotating locking hook 13 is rotated to clamp or unclamp the iron barrel mouth, the worker holds the handle 132 and the force assisting rod 125 at the same time, and then presses the handle 132, the lower surface of the handle 132 is abutted against the force assisting rod 125, and the top end of the force assisting rod 125 is used as the fulcrum, so that the handle 132 can be easily pried. Thus, the use of the barrel mouth clamp is facilitated, and the rotating locking hook 13 can be more easily rotated to clamp or unclamp the iron barrel mouth.

[0064] As an optional embodiment, a fastener is installed on the arc surface of the arc-shaped seat 705, and the fastener is used to replace the barrel mouth clamp. Figure 4 As shown, the fastener includes a screw rod, a fastening plate 707 and at least one nut 708. Threaded holes are formed on the arc surface of the arc-shaped seat 705 along the radial direction of the arc-shaped seat 705, the screw rod is threadedly connected in the threaded holes, the fastening plate 707 is used as the fastener, and a circular hole is formed on the fastening plate 707.

[0065] Thus, when the alloy sample pouring device is moved close to the iron barrel, the arc-shaped groove of the connecting bottom plate 702 is abutted against the iron barrel, and the arc surface of the arc-shaped seat 705 is also abutted against the iron barrel. Then, the fastening plate 707 is inserted into the screw rod, the lower end of the fastening plate 707 is inserted into the interior of the iron barrel, and finally the nut 708 is screwed on the end of the screw rod and is tightened. Under the action of the nut 708, the fastening plate 707 tightly presses the barrel mouth of the iron barrel, so that the iron barrel is fixed, and the state as shown is achieved. Finally, the hydraulic cylinder 10 is started, the hydraulic cylinder 10 is elongated to drive the boom connecting rod mechanism to pull the iron barrel bracket 7 to move along the guide rail 8 upward. When the iron barrel bracket 7 moves to the arc-shaped rail 801, the iron barrel on the iron barrel bracket 7 is gradually inclined, so that the precious metal alloy in the iron barrel is poured into the receiving hopper 9. Figure 3

[0066] Preferably, the fastening plate 707 is an arc-shaped plate which is matched with the iron barrel. Of course, the fastening plate 707 can also be arranged in a rectangular plate shape or other shapes.

[0067] In this embodiment, as shown, mounting holes are formed on the table top of the trolley 1, the receiving hopper 9 is arranged in the mounting holes, and the top of the receiving hopper 9 is hinged to the table top of the trolley 1 by a hinge, so that the receiving hopper 9 can be easily lifted when needed. Figure 1

[0068] ​​The receiving hopper 9 is a conical hopper. Of course, the receiving hopper 9 can also be other types of hoppers.

[0069] It should be noted that a receiving bucket for receiving the alloy is placed on the chassis of the trolley 1, and the receiving bucket needs to be placed directly below the receiving hopper 9 to receive the alloy falling from the discharge port 901 of the receiving hopper 9.

[0070] Since the receiving bucket is divided into a large bucket and a small bucket, when a large receiving bucket is used to receive the alloy, the height difference between the mouth of the large receiving bucket and the discharge port 901 of the receiving hopper 9 is small, so that the alloy will not splash and dust when receiving. However, when a small receiving bucket is used to receive the alloy, the height difference between the mouth of the small receiving bucket and the discharge port 901 of the receiving hopper 9 is large, so that the alloy will splash and dust. To solve this technical problem, a guide cylinder is provided, which is funnel-shaped. The bottom opening diameter of the funnel-shaped guide cylinder is smaller than the right angle of the discharge port 901 of the receiving hopper 9. When installing the guide cylinder, the guide cylinder is inserted into the receiving hopper 9 from above the receiving hopper 9, the bottom of the guide cylinder passes through the discharge port 901 of the receiving hopper 9, and the top outer side of the guide cylinder is attached to the inner side of the receiving hopper 9. In this way, the height difference between the small receiving bucket and the receiving hopper 9 can be compensated for, and the problem of alloy splashing and dust caused by the large height difference between the small receiving bucket and the receiving hopper 9 can be avoided.

[0071] In addition, it should be noted that since the receiving hopper 9 is hingedly installed on the table top of the trolley 1, when the space for placing a large receiving bucket is limited, the receiving hopper 9 is lifted at this time, and the height of the receiving hopper 9 is appropriately raised, and then the large receiving bucket is placed in the space below the receiving hopper 9.

[0072] It should be noted that the alloy sampling and pouring device is also provided with a remote controller and a control module. A hydraulic system is installed inside the trolley 1, which includes a hydraulic cylinder 10, a hydraulic pump, an oil tank, solenoid valves, pressure valves, and a receiver, etc. The hydraulic pump is used to pump hydraulic oil from the oil tank and pressurize it, and then deliver it to the hydraulic cylinder 10 through a pipeline. The solenoid valve is located between the hydraulic pump and the hydraulic cylinder 10, which controls the path of the hydraulic oil flowing to the hydraulic cylinder 10, thereby controlling the extension and retraction of the hydraulic cylinder 10.

[0073] The receiver is installed in the control box of the hydraulic system, which receives signals from the remote controller and converts them into electrical signals.

[0074] The instructions sent by the remote controller are transmitted to the receiver of the hydraulic system through wireless signals or wired connection. The remote controller can be wireless, using radio frequency, Bluetooth or other wireless technologies; or wired, such as through a cable connection.

[0075] The receiver sends the electrical signal to the control module. The control module can be a PLC (Programmable Logic Controller) or other type of controller, which controls the solenoid valves in the hydraulic system according to the received signal.

[0076] The solenoid valve is a key component in the hydraulic system, which opens or closes the flow path of hydraulic oil according to the instructions of the control module. The solenoid valve can be a proportional valve for precise control of oil flow, or a on-off valve for simple on / off control.

[0077] In addition, a power supply is also installed in the trolley 1, which is four 12V, 60ah lead-acid batteries, which supply power to each electrical component. Even if the factory power is off, it does not affect the normal use of the alloy sampling and pouring device.

[0078] It should be noted that the particle size of the alloy in the iron bucket is 30mm-60mm, the single block weight is 0.5-2kg, and the shape is irregular. Direct pouring will form a dent on the inner surface of the receiving hopper 9. In order to solve this technical problem, the rubber skin with appropriate thickness and softness is cut and shaped according to the model of the receiving hopper 9, and then naturally attached to the inner surface of the receiving hopper 9, which can avoid the dent, burr and noise caused by the hard contact between the alloy and the hopper steel plate.

[0079] In this embodiment, considering that when the iron bucket is taken, the iron bucket is located at the front end of the trolley 1 (i.e. Figure 1 The left side of the trolley 1), which will cause the front end of the trolley 1 to be too heavy and the rear end to be too light, thereby causing the trolley 1 to be warped. Therefore, the two wheels on the front side of the trolley 1 can be moved forward, and the rear end can be appropriately counterweighted, for example, by placing counterweight blocks in the cavity of the trolley 1, which can effectively prevent the problem of the trolley 1 being warped due to excessive load.

[0080] As an optional embodiment, a handle 102 is installed at the rear end of the trolley 1, which facilitates pushing the trolley 1.

[0081] In this embodiment, a power switch and a charging port are installed on the trolley 1, and the power switch and the charging port are respectively connected with the power supply wire mentioned above. The power switch controls the on-off of the power supply, and the charging port charges the power supply.

[0082] When using the alloy sampling and pouring device to take material, it generally includes the following steps:

[0083] Step one: prepare a suitable empty bucket as a receiving bucket, and then place the receiving bucket into the space below the receiving hopper 9.

[0084] Step two: push the trolley 1 to the iron bucket to be sampled, and then use the bucket mouth clamp or the fastener mentioned above to fix the bucket mouth.

[0085] Step three: open the power switch, press the remote control up button, realize automatic pouring. And can be released at any time button or point down button. Sampling can be taken from the top of the iron bucket, also can be taken from the lower receiving barrel.

[0086] Step four: sampling is completed, pull out the trolley 1, put down the original iron bucket, remove the receiving barrel and place it in the appropriate position.

[0087] Step five: the cycle operation completes all sampling, finally turn off the power switch, and charge the battery during the spare time.

[0088] In this way, a single person can operate sampling, changing the previous 3-4 people cooperation, even the condition of the crown crane, improving work efficiency, reducing labor intensity and danger, and without artificial weight lifting bucket, releasing the crown crane and other human resources, even if the power is off, the crown crane is busy or fails to affect the sampling work.

[0089] In addition, the alloy sampling and pouring device can not only be used for automatic pouring in quality sampling and production ingredient links, but also can play a carrying function for adjusting the position of the barrel alloy. The whole alloy sampling and pouring device is small in overall shape, occupies an area of 0.55m 3 , meets the iron bucket carrying, lifting and turning pouring work of the iron bucket with a diameter of 300mm-420mm, a height of 300mm-700mm and a weight of less than 300kg.
