Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 to 3, the present embodiment provides a hydraulic lifting device, which includes a frame, a lifting platform, a first hydraulic cylinder 1, an unpowered trolley 2, and a second hydraulic cylinder 3. First pneumatic cylinder 1 slides from top to bottom along the frame for driving the elevating platform, the elevating platform includes lifter plate 17 and the fixed box that sets up on the elevating platform, the box includes bottom plate 4, fixed plate 5 and rotor plate 6, the lower extreme of fixed plate 5 is fixed in on bottom plate 4, the lower extreme and the bottom plate 4 of rotor plate 6 pass through the hinge rotation and are connected, the one end rotation of second pneumatic cylinder 3 is connected in the outside of fixed plate 5, the other end and the rotor plate 6 of second pneumatic cylinder 3 rotate and are connected, second pneumatic cylinder 3 is used for driving rotor plate 6 and rotates, be provided with respectively on the bottom plate 4 and the inboard of rotor plate 6 and be used for carrying out the first guide rail 7 and the second guide rail 8 that lead to unpowered dolly 2.

During the use, will wait to go up and down the goods and place on unpowered dolly 2 earlier, open rotor plate 6, unpowered dolly 2 gets into in the box along first guide rail 7 and second guide rail 8, later close rotor plate 6, wait that the elevating platform goes up and down to open rotor plate 6 behind the assigned height, unpowered dolly 2 moves to the box outside along first guide rail 7 and second guide rail 8. This embodiment can make things convenient for the horizontal transport of goods through setting up unpowered dolly 2 and first guide rail 7 and second guide rail 8, can improve the security of freight process through setting up the box.

In this embodiment, the frame includes base 9, upper cover 10 and four uprights 11 for connecting base 9 and upper cover 10, and four uprights 11 are square distribution, are provided with the through-hole that matches with upright 11 shape on lifter plate 17, make lifter plate 17 not take place to rotate when sliding from top to bottom along upright 11. Other frame configurations may be selected by those skilled in the art so long as they guide the vertical motion of the lift table.

In this embodiment, the fixed plates 5 are three and perpendicular to each other, and the rotating plate 6 can enclose a square groove structure with the three fixed plates 5 after rotating to a vertical position. The square groove can limit the movement of the unpowered trolley 2, and a person skilled in the art can reasonably adjust the position relation between the fixed plate 5 and the rotating plate 6, so long as the unpowered trolley 2 can be limited after the rotating plate 6 rotates to the vertical position.

Furthermore, in order to prevent the unpowered trolley 2 from shaking along the first guide rail 7 when moving up and down along with the lifting platform, an electromagnet 12 is further arranged on the inner side of the fixed plate 5 opposite to the rotating plate 6, and an iron plate 13 opposite to the electromagnet 12 is arranged on the unpowered trolley 2. By electrifying the electromagnet 12, the unpowered trolley 2 can be firmly adsorbed on the electromagnet 12, thereby improving the safety of the conveying process.

Furthermore, as the unpowered car 2 and the electromagnet 12 approach each other, the attraction force between the iron plate 13 and the electromagnet 12 gradually increases, and in order to prevent the shock caused by the sudden stop of the unpowered car 2, the present embodiment is provided with a buffer spring 14 on the inner side of the fixed plate 5 opposite to the rotating plate 6, and the buffer spring 14 is configured to elastically contact the unpowered car 2. The buffer spring 14 can buffer the unpowered trolley 2 on one hand, and can provide outward auxiliary thrust for the unpowered trolley 2 when the electromagnet 12 is not electrified, so that the unpowered trolley 2 can be conveniently moved outwards.

When the weight of the unpowered trolley 2 is larger, the auxiliary thrust provided by the buffer spring 14 is not enough to move the unpowered trolley 2 out, and therefore, a third hydraulic cylinder 15 is further arranged on the inner side of the fixed plate 5 opposite to the rotating plate 6 in the embodiment, and a piston rod of the third hydraulic cylinder 15 is used for pushing the unpowered trolley 2 to move outwards.

In order to avoid the situation that the thrust exerted by the free end of the piston rod of the third hydraulic cylinder 15 on the unpowered trolley 2 is too concentrated to deform or crack the unpowered trolley 2, in the embodiment, the free end of the piston rod of the third hydraulic cylinder 15 is fixed with the push plate 16, and the push plate 16 is provided with the buffer gasket, and the buffer gasket is preferably made of rubber. Since the driving manner of the hydraulic cylinder and the electromagnet 12 is common knowledge in the art, the description thereof is omitted.

The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
