DETAILED DESCRIPTION

[0026] In order to better understand the present application, the following examples are described in conjunction with the drawings, which belong to the protection scope of the present application, but do not limit the protection scope of the present application.

[0027] Example 1

[0028] An electrically driven crane, such as Figures 1-5 As shown, it includes: a pushing assembly 1, including: casters 11; axle brackets 12, with both sides connected to the casters 11; an inner axle tube 13, with its bottom connected to the axle bracket 12; an outer axle tube 14, disposed on the axle bracket 12, with the inner axle tube 13 inside it; a lifting assembly 2, including: a lifting device 21, with its bottom end disposed on the outer axle tube 14; an upper support beam 22, with one end hinged to the outer axle tube 14; a lower support beam 23, with one end hinged to the lifting device 21; a lifting beam frame 24, with both sides hinged to the other ends of the upper support beam 22 and the lower support beam 23, respectively; and several load-bearing axle rods 25, spaced apart on the lifting beam frame 22; the lifting beam frame 24 and the outer axle tube 14 are respectively disposed on both sides of the lifting device 21.

[0029] like Figures 1-5 As shown, the upper support beam 22 is located above the lower support beam 23, and the two are arranged parallel to each other; the upper support beam 22 and the lower support beam 23 do not contact the lifting device 21.

[0030] The outer tube increases the surface area, making it easier to securely install components such as lifting devices, upper support beams, and lower support beams. It also protects the inner tube from foreign objects falling in and affecting normal use.

[0031] The inner shaft tube is connected to the wheel axle frame by bearings. There are two casters, which are set opposite each other on both sides of the wheel axle frame. They are solid rubber wheels with a large load-bearing capacity to meet the needs of transporting heavy objects.

[0032] The lifting device uses an electro-hydraulic cylinder, or similar existing products such as an electric actuator; when in use, the lifting rod rises, which drives the lower support beam to rotate upward, thereby causing the upper support beam to rotate upward, thus raising the support beam frame and lifting the item through the load-bearing shaft.

[0033] The upper support beam is connected to the outer shaft tube and the lifting beam frame at both ends, and the lower support beam is connected to the outer shaft tube and the lifting beam frame at both ends, making the connection more stable and ensuring greater stability during lifting.

[0034] The load-bearing beam has four load-bearing shafts, two at the top and two at the bottom, corresponding to the container crossarm beams at the top and bottom of the box ammunition. Before use, pre-drill through holes at appropriate positions on the container crossarm beams. When in use, insert the load-bearing shafts of the crane into the holes of the crossarm beams, and then control the lifting device to lift the box ammunition.

[0035] The use method is as follows: a plurality of box-type ammunitions to be transported are assembled by using the container cross beam, the jacks are moved to appropriate positions and placed symmetrically, the load shaft rods of the jacks are respectively inserted into the pre-set holes of the upper and lower cross beam, then the lifting mechanism is started, the lifting rod is lifted to drive one end of the lower support beam to rotate upward, and then the upper support beam is rotated upward, so that the ammunition is supported; then one person pushes one jack or the jack is mechanically pulled to an appropriate position; after reaching the designated position, the lifting rod of the lifting device is controlled to retract downward, so that one end of the lower support beam rotates downward, and then the upper support beam is driven to rotate downward, so that the ammunition to be transported is stably placed on the ground, and the jack is pushed away.

[0036] Embodiment 2

[0037] Compared with embodiment 1, the jack further has the following technical features:

[0038] As shown in Figures 1-5 , the lifting assembly 2 further comprises: an eccentric rod 26 arranged in the load shaft rod 25; an eccentric head 27 arranged at one end of the eccentric rod 26 away from the lifting beam frame 22; and an eccentric tail 28 arranged at the other end of the eccentric rod 26 opposite the eccentric head 27. The eccentric tail 28 can drive the eccentric rod 26 and the eccentric head 27 to rotate relative to the lifting beam frame 24, and can be locked on the lifting beam frame 24 through a fixing piece.

[0039] As shown in Figures 1-5 , the lifting assembly 2 further comprises: a measuring scale 29 movably arranged on the side surface of the outer shaft tube 14, and the top thereof is connected with the lifting rod of the lifting device 21.

[0040] The eccentric rod tail end is connected with the eccentric head, the middle line of the eccentric rod is located on one side of the middle line of the eccentric head, so that the distances from the two sides of the eccentric rod to the edge of the eccentric head are different; rotating the eccentric tail rod can drive the eccentric rod to rotate, and then drive the eccentric head to rotate; after the load shaft rod passes through the hole of the cross beam, rotating the eccentric tail rod can make the eccentric head protrude upward from the load shaft rod, which has the effect of clamping and prevents the load from falling off during transportation, ensuring safety; in specific use, the eccentric tail rod is in an open state, the load shaft rod is inserted into the hole of the cross beam, and then the eccentric tail rod is rotated to the locked position and locked; at this time, the container cross beam is located at the smaller end of the load shaft rod (the smaller end of the load shaft rod is closer to the eccentric head), and the locked eccentric head protrudes upward from the load shaft rod, so that the ammunition can be clamped; the open / locked state of the eccentric tail rod corresponds to the open hole in the position of the load beam frame, and then the load tail rod and the load beam frame can be locked or unlocked by using a latch. Figure 1

[0041] The measuring scale arranged can facilitate the user to intuitively see the lifting height of the lifting rod of the lifting device during use, and then know the lifting height of the jack for the ammunition, meeting the actual use requirement.

[0042] Embodiment 3​

[0043] Compared with the embodiment 1, the jack further has the following technical features:

[0044] As shown in Figures 1-5 , the jack further comprises: an auxiliary assembly 3, comprising: a fixed column 31 arranged on the wheel shaft frame 12 away from one end of the lifting beam frame 24; a connecting block 32 arranged on the fixed column 31, and a connecting hole is formed in the connecting block 32.

[0045] As shown in Figures 1-5 , the auxiliary assembly 3 further comprises: a sleeve 33 arranged on the outside of the lifting beam frame 24; a manual steering rod 34, the top of which is in a U-shaped structure and is clamped in the sleeve 33; and a connecting head 35 arranged on the top of the manual steering rod 33 and in a U-shaped structure.

[0046] As shown in Figures 1-5 , the auxiliary assembly 3 further comprises: a grounding copper drag chain 36, one end of which is arranged on the wheel shaft frame 12 and the other end of which is in contact with the ground.

[0047] As shown in Figures 1-5 , the jack further comprises: a battery 37 arranged on the outside of the outer shaft tube 14 and above the connecting block 32; a handle 38 arranged on the top of the outer shaft tube 14 and above the battery 37; and a controller 39 arranged on the handle 38; the controller 39 is in control connection with the lifting device 21.

[0048] During the transfer process, sometimes mechanical traction is needed. In order to ensure the synchronous movement of the jack, two jacks near one end of the traction equipment (such as a tractor) can be connected together, and then traction is performed through the traction equipment. When traction is needed, the connecting holes on the connecting blocks at both ends of the connecting rod are respectively connected in rotation, the V-shaped traction rod is connected to the connecting holes on the wheel shaft frames of the two jacks at both sides of one end of the V-shaped traction rod, and the other end of the V-shaped traction rod is connected to the tractor.

[0049] During the process of manually pushing the jack, turning and other actions may be needed. At this time, the manual steering rod can be taken out of the sleeve, the U-shaped connecting head is connected to the fixed column and fixed by a latch and the like, and then the steering action is performed by pushing the manual steering rod to meet the use requirements. After use, the latch can be removed and the manual steering rod can be inserted into the sleeve. The diameter of the connecting head is greater than the diameter of the sleeve, so that the connecting head can be clamped on the sleeve.

[0050] One end of the grounding copper drag chain is arranged on the wheel shaft frame, and the other end is in contact with the ground, so that the static electricity generated during use can be conducted to the ground, improving the safety of use.

[0051] The set battery can provide power for the operation of the lifting device and the controller, and ensure the normal operation of the related electrical components; the battery and the outer shaft tube can be connected by screws and other fixing members, and when the battery power is low, it can be connected to the mains through the power cord for charging; when manually pushing, the handle is set to facilitate the operator to push.

[0052] The controller is connected with the lifting device for control, and the start and stop control can be easily realized by the keys on the controller, improving the operation convenience; when the size of the to-be-transported object is large, multiple hoists (for example, four hoists, two in front and two at the back) are needed for operation, and the operator can press the controller buttons of the four hoists at the same time to realize the operation of multiple synchronous operation.

[0053] The lifting device, battery, controller and other components of the present application are not the innovation points of the present application, and the specific models are not described here, and the installation and connection are all in the existing manner.

[0054] It should be noted that in this text, relational terms such as first and second are used merely to distinguish one entity or action from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or actions. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the statement "including a limited element" does not exclude the existence of other identical elements in the process, method, article or equipment including the element.

[0055] The above is only the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
