Description

Technical Field

[0001] This utility model relates to the technical field of dangerous goods transportation equipment, specifically an explosion-proof horizontal ammunition transport trolley, which is particularly suitable for the explosion-proof transportation of highly dangerous agents such as powdered or granular explosives. Background Technology

[0002] Currently, indoor ammunition transport mainly relies on manual carrying or simple trolleys. This method lacks any enclosure or protective mechanism, leaving the ammunition directly exposed to the external environment. For example, during handling, ammunition boxes may experience violent impacts due to human error or environmental factors. Ammunition often contains powdered or granular agents, which are extremely sensitive to friction and static electricity. Without protection, even a slight collision can trigger friction and heating between the agents, leading to an accidental explosion.

[0003] In confined indoor environments such as ammunition depots or laboratory corridors, the shockwave from an explosion cannot be absorbed or isolated, and the instantaneously released energy can cause a chain reaction. This can lead to casualties and facility damage. The accidental explosion rate in traditional transportation is as high as 5% or more on average in the industry, highlighting the gaps in safety protection.

[0004] Chinese utility model patent CN214689631U provides an ammunition transport trolley, including a pallet and a walking mechanism, which facilitates ammunition transport, reduces transport risks, and can quickly form a support after being transported to a designated location, transforming it into a placement bracket; it isolates the ammunition from the ground, increasing moisture protection; it is easy to operate, has a simple structure, and is convenient to use. However, this design does not consider factors such as severe impacts due to human error or environmental factors, does not discharge static electricity from the transport device, and does not have explosion-proof isolation, posing a significant risk during ammunition transport.

[0005] Therefore, there is an urgent need to develop an explosion-proof horizontal ammunition transport trolley to solve the above problems. Utility Model Content

[0006] This utility model is an explosion-proof horizontal ammunition transport trolley. By setting up a horizontal explosion-proof ball machine anti-static handcart, the ammunition is clamped to reduce friction during delivery. The setting of an anti-static belt effectively reduces static electricity during delivery, thereby reducing the risk of ammunition transportation. At the same time, the modular components make it easy to maintain, significantly improving personnel safety and effectively solving the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof horizontal ammunition transport trolley, comprising: a horizontal explosion-proof ball and an anti-static handcart; the horizontal explosion-proof ball is bolted and fixed to the anti-static handcart.

[0008] The horizontal explosion-proof sphere includes a sphere, a switching mechanism, a bracket, a locking device, and a tray. The bracket is fixedly connected to an anti-static handcart at the bottom, and the sphere is fixedly connected to the top of the bracket. A switching mechanism, a sphere cover, and a locking device are movably connected to one side of the sphere, and a tray is fixedly connected to the inside of the sphere.

[0009] The anti-static handcart includes a body, a handle, a brake lever, casters, and a static-dissipating belt. Casters are located under the body, a static-dissipating belt is located under the body, a handle is located on one side of the body, and a brake lever is located in the middle of the handle.

[0010] Preferably, the sphere is placed horizontally, the switching mechanism is fixedly connected to the sphere cover, the outer side of the sphere cover is provided with equally spaced extension structures, and the sphere is provided with a valve plate corresponding to the shape of the sphere cover.

[0011] Preferably, the locking device is a self-locking device, and the locking device self-locks when the ball cover is fully closed.

[0012] Preferably, support rods are fixedly connected to both sides of the tray, and the tray is bolted to the ball through the support rods. A clamping device is provided at the front end of the tray, and the clamping device is fixedly connected to the tray to hold and fix the ammunition.

[0013] Preferably, the electrostatic conductive strip is bolted to the bracket, and both the sphere and the bracket are made of conductive materials.

[0014] Preferably, a brake cable is provided below the brake lever, and the brake cable is fixedly connected to the caster below.

[0015] Preferably, the caster unlocks and rotates when the brake lever is pulled toward the handrail, and locks when the brake lever is moved away from the handrail.

[0016] Beneficial effects

[0017] This utility model provides an explosion-proof horizontal ammunition transport cart, which has the following advantages compared with the existing technology:

[0018] The ammunition of this utility model is enclosed in a horizontal explosion-proof sphere, forming an explosion-proof sealed space. The sphere is made of high-strength material, which can absorb and disperse the shock wave of an explosion. When the internal agent explodes accidentally, the shock wave is blocked and weakened by the sphere wall, limiting the kill range to inside the equipment. The clamping device fixes the ammunition box, avoiding friction fire caused by shaking during transportation.

[0019] The brake lever and handle of this anti-static handcart are designed in a linkage manner. When operating, holding the handle with both hands will unlock the casters, making it easy to push. After releasing the brake lever, it will automatically lock to prevent accidental slippage. The static discharge strap continuously discharges static charge to avoid spark ignition and eliminate the risk of accumulation in dry environments.

[0020] This invention effectively reduces the risks and hazards of ammunition during transportation, and its modular components facilitate maintenance, significantly improving personnel safety. Attached Figure Description
