Description

Technical Field

[0001] This invention relates to the field of civilian explosives production technology, and in particular to an explosives loading and unloading device. Background Technology

[0002] Explosives are commonly used in engineering blasting and combat operations, and are classified as Class 1 hazardous materials internationally. Explosives are sensitive to hazards such as friction, impact, and high temperatures; improper handling can easily lead to accidental explosions and catastrophic consequences. On the one hand, to prevent and reduce safety accidents in explosives production and protect the lives and property of the public, comprehensive regulations have been established for the production and storage of explosives, prohibiting the storage of electrical equipment, especially power electrical equipment. On the other hand, with technological advancements and social development, relevant enterprises are also demanding more sophisticated containerized and mechanized storage of explosives. Summary of the Invention

[0003] This invention provides an explosives loading and unloading device to achieve a mechanized loading and unloading operation of explosives without the need for a power source.

[0004] This invention provides an explosives loading and unloading device, comprising: a gravity conveyor, two sets of support seats, and a hoisting mechanism, wherein the two sets of support seats are respectively disposed on both sides of the gravity conveyor; wherein,

[0005] The gravity conveyor includes a base frame rotatably connected to two sets of support seats via pins. The base frame is provided with a support beam, and the support beam is provided with a roller guide rail and a stop structure at one end near the support seat. The base frame has a circular through hole at one end near the support seat for installing a winch cable end shaft. The winch cable end shaft is connected to the winch cable of the winch mechanism so that the gravity conveyor can rotate around the pin under the pull of the winch mechanism.

[0006] Both sets of support seats are located on the side of the hoisting mechanism close to the gravity conveyor, and each set of support seats is provided with a waist-shaped through hole of the same size, so that the pin can rotate in the waist-shaped through hole and move up and down in the vertical direction along the waist-shaped through hole under the pull of the hoisting cable.

[0007] In some embodiments of the present invention, the hoisting mechanism includes a hydraulic motor, a hydraulic motor base, a drum, a drum shaft, a drum shaft base, a hoisting cable, and a gantry; wherein,

[0008] The gantry is respectively located on the outside of the two sets of support seats, away from the gravity conveyor. One gantry is provided with the hydraulic motor base on its side, and the hydraulic motor is installed on the outside of the hydraulic motor base away from the support seat. The other gantry is provided with the drum shaft base. The drum shaft is coaxially connected to the two drums, and then coaxially connected to the hydraulic motor and the drum shaft base.

[0009] Both drums are wound with winch cables, and the end of each winch cable is connected to the winch cable end shaft on the corresponding side of the gravity conveyor.

[0010] In some embodiments of the present invention, the pin passes through the circular through hole of the base frame and the waist-shaped through holes of the two support seats, and the pin can slide along the length direction of the waist-shaped through holes of the two support seats.

[0011] When the hydraulic motor of the winch mechanism rotates, the gravity conveyor can be rotated around the pin and slid along the waist-shaped through hole of the support seat via the winch cable.

[0012] In some embodiments of the present invention, when the gravity conveyor is not in operation, the winch is in a tightened state, the gravity conveyor is flipped to a first set angle under the lifting action of the winch, and the pin is raised to the upper limit position along the waist-shaped through hole of the support seat, and the gravity conveyor exits the ammunition magazine opening.

[0013] In some embodiments of the present invention, when the gravity conveyor is performing explosive unloading operations, the winch is released, and the gravity conveyor, under its own weight, causes the pin to descend along the waist-shaped through hole of the support seat. The gravity conveyor rotates counterclockwise around the pin until the side of the gravity conveyor away from the support seat is mounted on the placement opening of the gravity rack. The pin slides along the waist-shaped through hole of the support seat to the lower limit position, so that the gravity conveyor is in a left-high-right-low state. Thus, after the explosive container unit unloaded from the gravity rack reaches the discharge port, it automatically moves onto the gravity conveyor under its own weight until the explosive container unit contacts the stop structure of the gravity conveyor, completing the explosive unloading operation.

[0014] In some embodiments of the present invention, when performing explosive storage operations, the winch is released, and the gravity conveyor, under the action of gravity, causes the pin to descend along the waist-shaped through hole of the support seat. The gravity conveyor rotates counterclockwise around the pin until the side of the gravity conveyor away from the support seat is mounted on the shelf opening of the gravity rack.

[0015] The hoisting cable of the hoisting mechanism is tensioned and contracted, lifting the right side of the gravity conveyor until the pin rises along the waist-shaped through hole of the support seat to the upper limit position, so that the gravity conveyor is in a left-low and right-high state. The container unit placed on the gravity conveyor automatically moves to the loading port of the gravity rack under its own gravity, completing the explosives storage operation.

[0016] In some embodiments of the invention, the roller guide includes a plurality of cylindrical rollers installed at equal intervals for supporting and conveying explosive container units.

[0017] In some embodiments of the present invention, the support base is installed on the ground outside the entrance of the explosives depot, and the winch mechanism is installed on the ground outside the support base.

[0018] Compared with the prior art, the beneficial effects of the explosives loading and unloading device provided in this embodiment of the invention are as follows: it realizes the mechanical transfer channel for explosives loading and unloading and the space clearance of the warehouse door when there are no explosives loading or unloading through a set of flipping conveying mechanism; it realizes gravity self-conveying slope through floating pin shaft and hoisting mechanism, and dynamically adapts to the height difference of the explosives warehouse inlet and outlet; thus, it can realize automatic loading and unloading of explosives without the premise of no power supply entering the warehouse.

[0033] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0034] This invention provides an explosives loading and unloading device, such as... Figures 1 to 6 As shown, it includes: a gravity conveyor 1, two sets of support seats 2, and a hoisting mechanism 3, with the two sets of support seats 2 respectively located on both sides of the gravity conveyor 1; wherein,

[0035] The gravity conveyor 1 includes a base frame 13 rotatably connected to two sets of support seats 2 via pins 15. The base frame 13 is provided with a support beam 12, and the support beam 12 is provided with a roller guide rail 11 and a stop structure 16 at one end near the support seat 2. The base frame 13 has a circular through hole at one end near the support seat 2 for installing a winch cable end shaft 14. The winch cable end shaft 14 is connected to the winch cable 36 of the winch mechanism 3 so that the gravity conveyor 1 can rotate around the pin 15 under the pull of the winch mechanism 3.

[0036] Both sets of support seats 2 are located on the side of the hoisting mechanism 3 near the gravity conveyor 1, and each set of support seats 2 is provided with a waist-shaped through hole of the same size, so that the pin shaft 15 can rotate in the waist-shaped through hole and move up and down in the vertical direction along the waist-shaped through hole under the pull of the hoisting cable 36.

[0037] In this embodiment, the hoisting mechanism 3 includes a hydraulic motor 31, a hydraulic motor base 32, a drum 33, a drum shaft 34, a drum shaft base 35, a hoisting cable 36, and a gantry 37. The gantry 37 is located on the outer side of each of the two sets of support seats 2, away from the gravity conveyor 1. One gantry 37 has the hydraulic motor base 32 mounted on its side, with the hydraulic motor 31 mounted on the outer side of the hydraulic motor base 32 away from the support seat 2. The other gantry 37 has the drum shaft base 35 mounted on it. The drum shaft 34 coaxially connects the two drums 33, and then coaxially connects the hydraulic motor 31 and the drum shaft base 35. The hoisting cable 36 is wound on both drums 33, and the end of each hoisting cable 36 is connected to the hoisting cable end shaft 14 on the corresponding side of the gravity conveyor 1.

[0038] Furthermore, in this embodiment, the pin 15 passes through and connects the circular through hole of the base frame 13 and the waist-shaped through holes of the two support seats 2, and the pin 15 can slide along the length direction of the waist-shaped through holes of the two support seats 2.

[0039] When the hydraulic motor 31 of the winch mechanism 3 rotates, the gravity conveyor 1 can be rotated around the pin 15 and slide along the waist-shaped through hole of the support seat 2 by the winch cable 36.

[0040] In some embodiments of the present invention, when the gravity conveyor 1 is not working, the winch cable 36 is in a tightened state, the gravity conveyor 1 is flipped to a first set angle under the lifting action of the winch cable 36, and the pin 15 is lifted to the upper limit position along the waist-shaped through hole of the support seat 2, and the gravity conveyor 1 exits the ammunition magazine opening.

[0041] In some embodiments of the present invention, when the gravity conveyor 1 performs explosive unloading operations, the winch cable 36 is released, and the gravity conveyor 1, under its own gravity, causes the pin 15 to descend along the waist-shaped through hole of the support seat 2. The gravity conveyor 1 rotates counterclockwise around the pin 15 until the side of the gravity conveyor 1 away from the support seat 2 is mounted on the shelf opening of the gravity rack. The pin 15 slides along the waist-shaped through hole of the support seat 2 to the lower limit position, so that the gravity conveyor 1 is in a left-high-right-low state (i.e., the side of the gravity conveyor 1 away from the support seat 2 is high). As a result, after the explosive container unit unloaded from the gravity rack reaches the loading port, it automatically moves onto the gravity conveyor 1 under its own gravity until the explosive container unit contacts the stop structure 16 of the gravity conveyor 1, completing the explosive unloading operation.

[0042] In some embodiments of the present invention, when the explosives are stored, the winch cable 36 is released, and the gravity conveyor 1, under the action of gravity, causes the pin 15 to descend along the waist-shaped through hole of the support seat 2. The gravity conveyor 1 rotates counterclockwise around the pin 15 until the side of the gravity conveyor 1 away from the support seat 2 is mounted on the shelf opening of the gravity rack.

[0043] The winch cable 36 of the winch mechanism 3 is tensioned and retracted, lifting the right side of the gravity conveyor 1 until the pin 15 rises along the waist-shaped through hole of the support seat 2 to the upper limit position, so that the gravity conveyor 1 is in a left-low-right-high state (that is, the side of the gravity conveyor 1 away from the support seat 2 is low). The container unit placed on the gravity conveyor 1 automatically moves to the loading port of the gravity rack under its own gravity, completing the explosives storage operation.

[0044] To facilitate understanding of the above technical solutions, the following detailed explanation is provided with reference to the accompanying drawings and specific examples:

[0045] Specifically, the aforementioned explosives loading and unloading device consists of a gravity conveyor 1, two sets of support bases 2, and a hoisting mechanism 3. The gravity conveyor 1 consists of roller guide rails 11, support beams 12, base frame 13, hoisting cable end shafts 14, pins 15, and stop structures 16; the hoisting mechanism 3 consists of a hydraulic motor 31, a hydraulic motor base 32, a drum 33, a drum shaft 34, a drum shaft base 35, a hoisting cable 36, and a gantry 37.

[0046] like Figure 1The roller guide rail 11 and the stop structure 16 of the gravity conveyor 1 are respectively installed above the support beam 12. Multiple cylindrical rollers are installed at equal intervals on the roller guide rail 11 to support and convey the explosive container unit. The support beam 12 is installed above the base frame 13, and a set of winch cable end shafts 14 is located on the outside of the base frame 13. The support base 2 is installed on the ground outside the entrance of the explosives depot, and the winch mechanism 3 is installed on the ground outside the support base 5.

[0047] like Figure 2 The hydraulic motor 31 of the hoisting mechanism 3 is installed on the outside of the hydraulic motor base 32. The hydraulic motor base 32 is installed on the side of one gantry 37. The drum shaft base 35 is installed on the side of another gantry 37. The drum shaft 34 is coaxially connected to the hydraulic motor 31 and two drums 33. The drums 33 are wound with hoisting cables 36. The ends of the two hoisting cables 36 are respectively connected to the two hoisting cable end shafts 14 of the gravity conveyor 1.

[0048] like Figure 2 and Figure 3 Near the hoisting cable end shaft 14 of the gravity conveyor 1, there is a circular through hole, and the support base 2 has a waist-shaped through hole. The pin 15 passes through and connects the circular through hole of the base frame 13 and the waist-shaped through hole of the support base 2, and the pin 15 can slide a certain distance along the waist-shaped through hole of the support base 2. When the hydraulic motor 31 of the hoisting mechanism 3 rotates, the gravity conveyor 1 can be rotated around the pin 15 and slide along the waist-shaped through hole of the support base 2 through the hoisting cable 36.

[0049] like Figure 1 and Figure 4 When the gravity conveyor 1 is not working, the winch cable 36 of the winch mechanism 3 is in a tightened state. Under the lifting action of the winch cable 36, the gravity conveyor 1 is flipped at a certain angle, and the pin 15 is lifted to the upper limit along the waist-shaped through hole of the support seat 2. The gravity conveyor 1 exits the ammunition depot opening.

[0050] like Figure 1 and Figure 5 When the gravity conveyor 1 performs explosive unloading operations, the winch cable 36 of the hoisting mechanism 3 is released. Under its own weight, the pin 15 of the gravity conveyor 1 descends along the waist-shaped through hole of the support base 2 and rotates counterclockwise around the pin 15 until the left side of the gravity conveyor 1 is mounted on the placement opening of the gravity rack. The pin 15 on the right side of the gravity conveyor 1 slides along the waist-shaped through hole of the support base 2 to the lower limit. At this time, the gravity conveyor 1 is in a left-high-right-low state. After the explosive container unit unloaded from the gravity rack reaches the loading port, it automatically moves onto the gravity conveyor 1 under its own weight until the explosive container unit contacts the stop structure 16 of the gravity conveyor 1, completing the explosive unloading operation.

[0051] like Figure 1 and Figure 6 When performing explosives storage operations, the winch cable 36 of the winch mechanism 3 is released. Under the action of gravity, the pin 15 of the gravity conveyor 1 descends along the waist-shaped through hole of the support base 2 and rotates counterclockwise around the pin 15 until the left side of the gravity conveyor 1 is mounted on the placement opening of the gravity rack. The winch cable 36 of the winch mechanism 3 is then tensioned and contracted, raising the right side of the gravity conveyor 1 until the pin 15 rises to its upper limit along the waist-shaped through hole of the support base 2. At this time, the gravity conveyor 1 is in a left-low, right-high state. The container unit placed on the gravity conveyor 1 automatically moves to the loading opening of the gravity rack under its own gravity, completing the explosives storage operation.

[0052] As can be seen from the above technical solutions, the explosives loading and unloading device provided in the above embodiments of the present invention realizes the mechanical transfer channel for explosives loading and unloading and the space clearance of the warehouse door when there are no explosives loading or unloading; through the floating pin shaft 15 and the hoisting mechanism 3, the gravity self-conveying slope is realized and dynamically adapts to the height difference of the explosives warehouse inlet and outlet; thus, it can realize the automatic loading and unloading of explosives without the need for power supply to enter the warehouse.

[0053] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
