Abstract
Description
Technical Field
[0001] This application relates to the technical field of material handling, and in particular to a push-pull explosion-proof electric forklift. Background Technology
[0002] Hand forklifts are a type of non-powered, two-wheeled trolley commonly used in the logistics industry. They are mainly used for short-distance material handling in warehouses, factories, supermarkets, and other similar locations. Hand forklifts can directly scoop up and place materials and are highly maneuverable, but they rely entirely on human power for propulsion. This results in significant physical exertion during operation, especially when pushing them uphill, and requires multiple people to assist in pushing and balancing them when moving heavy objects.
[0003] In the military field, to facilitate the transport of flammable and explosive hazardous materials such as ammunition, explosion-proof containers are typically placed on forklifts. Operators can then transport both other goods and explosion-proof items. Generally, the explosion-proof containers are simply secured to the forklift with straps, lacking other effective restraint mechanisms. This results in significant shaking of the containers during transport, severely impacting the stability of the transport and requiring improvement. Utility Model Content
[0004] The purpose of this application is to provide a push-pull explosion-proof electric forklift to improve the stability of the explosion-proof box installed on the forklift.
[0005] This application provides a push-pull explosion-proof electric forklift with the following technical solution: It includes a movable frame, on which an explosion-proof box is placed; a chassis is rotatably connected to the movable frame; a handrail is provided at the top of the chassis; a fork is provided at the bottom of the chassis; several rollers are rotatably connected to the movable frame; the movable frame is provided with two limiting plates and at least one support plate; the support plate is located between the two limiting plates; the support plate is provided with a positioning groove for cooperating with the explosion-proof box; and binding straps are fitted onto the limiting plates for binding the explosion-proof box.
[0006] By adopting the above technical solution, the explosion-proof box is placed in the positioning groove and positioned between two limiting plates. The outer surface of the explosion-proof box abuts against the inner wall of the positioning groove and also abuts against the opposite side of the two limiting plates. The cooperation between the support plate and the two limiting plates restricts the horizontal movement of the explosion-proof box, thereby improving the stability of the explosion-proof box installed on the forklift. The explosion-proof box is then secured with straps, further improving its stability on the forklift.
[0007] Optionally, the mobile frame includes a connecting plate and two support plates, both of which are connected to the connecting plate. The frame is rotatably connected to the connecting plate. The connecting plate and the support plates are rotatably connected to the rollers. The support plate and the limiting plate are both connected to the support plates.
[0008] By adopting the above technical solution, the mobile frame consists of only a connecting plate and two support plates, which has a simple structure, fewer parts, reduced weight, and facilitates the movement of the mobile frame.
[0009] Optionally, the limiting plate is detachably connected to the support plate, and the support plate is connected to an adjustment structure for adjusting the distance between the two limiting plates.
[0010] By adopting the above technical solution, the adjustment structure can adjust the distance between the two limiting plates, which can be adapted to explosion-proof boxes of different sizes, improving the versatility of the device and the stability of conveying explosion-proof boxes of different specifications.
[0011] Optionally, the limiting plate is provided with a guide groove, which is used for the two support plates to engage.
[0012] By adopting the above technical solution, the cooperation between the two support plates and the guide groove plays a guiding and limiting role in adjusting the position of the limiting plate, so that the limiting plate can move accurately to the corresponding position.
[0013] Optionally, the adjustment structure includes a bolt and a nut threaded onto the bolt, the support plate is provided with a waist-shaped hole, the extension direction of the waist-shaped hole is the same as the adjustment direction of the limiting plate, and the threaded end of the bolt passes through the limiting plate and the waist-shaped hole and is located in the guide groove.
[0014] By adopting the above technical solution, the limiting plate can move when the nut is loosened. The sliding fit between the bolt and the slotted hole guides and limits the sliding of the limiting plate, thereby improving the stability of the limiting plate's movement and allowing the limiting plate to move accurately to the corresponding position. After the position of the limiting plate is adjusted, the nut is rotated, and the nut abuts against the support plate. The limiting plate is clamped by the support plate and one end of the bolt, thus fixing the limiting plate again.
[0015] Optionally, the support plate is connected to a locking element, which is used to fix or loosen the support plate.
[0016] By adopting the above technical solution, the support plate can be easily disassembled and installed by fixing or loosening the support plate by connecting the locking parts to the support plate. Different support plates can be replaced, i.e., the positioning grooves are of different sizes, so as to adapt to explosion-proof boxes of different specifications.
[0017] Optionally, two of the support plates are spaced apart and connected to the support plate.
[0018] By adopting the above technical solution, the two support plates can support the explosion-proof box from multiple positions, improving the support stability of the explosion-proof box and thus enhancing the stability of the explosion-proof box during transportation.
[0019] Optionally, the support plate includes a reinforcing rod, a crossbar, and two vertical rods disposed on the crossbar. The two vertical rods are respectively disposed at both ends of the crossbar. Each vertical rod is rotatably connected to the roller. The two ends of the reinforcing rod are respectively connected to the two vertical rods. The reinforcing rod is provided with a reinforcing part, and the reinforcing part is connected to the crossbar.
[0020] By adopting the above technical solution, the reinforcing rod is connected to the vertical rod and to the horizontal rod through the reinforcing part, making the overall structure of the mobile frame more stable, improving the overall stability and load-bearing capacity of the forklift, and thus enhancing the stability of the explosion-proof box transportation.
[0021] Optionally, each of the limiting plates is provided with a limiting channel for the binding strap to pass through.
[0022] By adopting the above technical solution, the binding strap passes through the limiting channel, which can prevent the binding strap from shifting or sliding during the binding of the explosion-proof box, thereby improving the fixing effect of the binding strap on the explosion-proof box and further enhancing the stability of the explosion-proof box during transportation.
[0023] Optionally, the inner wall of the limiting channel is arc-shaped.
[0024] By adopting the above technical solution, the arc-shaped inner wall disperses pressure and protects the binding strap.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. Place the explosion-proof box in the positioning slot, with the box positioned between the two limiting plates. The outer surface of the box abuts against the inner wall of the positioning slot and against the opposite side of the two limiting plates. The cooperation of the support plate and the two limiting plates restricts the horizontal movement of the explosion-proof box, thereby improving its stability when mounted on the forklift. The explosion-proof box is then secured with straps, further enhancing its stability on the forklift.
[0027] 2. The adjustable structure allows for adjustment of the distance between the two limit plates, enabling it to adapt to explosion-proof boxes of different sizes, thus improving the versatility of the device and the stability of conveying explosion-proof boxes of different specifications.
