[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] See also Figure 1As shown;

[0049] This embodiment discloses an electric safety operating device for quickly replacing a fixture on a crane carriage, the operating device comprising:

[0050] Bottom frame 1;

[0051] A load-bearing frame 2 movably connected to the bottom frame 1; and

[0052] A hydraulic jacking device 3 is provided between the bottom frame 1 and the load-bearing frame 2, and the load-bearing frame 2 can be driven to move in the vertical direction by the hydraulic jacking device 3;

[0053] The upper end of the load-bearing frame 2 is a load-bearing plate 202, which is used to support the truck;

[0054] The bottom of the bottom frame 1 is integrated with a moving roller 102;

[0055] The hydraulic jacking device 3 has a jacking limit mechanism 5, which is used to limit the height of the hydraulic jacking device 3 lifting the load-bearing plate 202.

[0056] Specifically, this embodiment discloses an electric safety operation device suitable for quickly replacing fixtures and overhead crane carts in the production of prebaked anodes for aluminum. The device includes a bottom frame 1 and a load-bearing frame 2. At the same time, a load-bearing plate 202 on the top of the load-bearing frame 2 is used to support the cart. In this embodiment, a hydraulic jacking device 3 is provided between the bottom frame 1 and the load-bearing frame 2. The hydraulic jacking device 3 is used to drive the load-bearing frame 2 to move in the vertical direction to adjust the height of the cart. The load-bearing frame 2 of this embodiment is slidably connected to the bottom frame 1. At the same time, in order to facilitate the movement of the cart position after supporting the cart, a movable roller 102 is integrated at the bottom of the bottom frame 1 of this embodiment, and the movable roller 102 of this embodiment is equipped with a brake device to achieve positioning and fixation.

[0057] At the same time, in order to adapt to the lifting height requirements of the hydraulic jacking device 3 for the load-bearing plate 202, this embodiment is designed with a jacking limit mechanism 5, which limits the lifting height of the driving end of the hydraulic jacking device 3 to avoid the load-bearing plate 202 from tilting upward.

[0058] Preferably, the bottom frame 1 of this embodiment includes:

[0059] A bottom frame support column 101, with a movable roller 102 at the bottom of the bottom frame support column 101;

[0060] A bottom plate 103 connected between the bottom frame support columns 101 and located below the bottom frame support columns 101; and

[0061] A fixing plate 104 connected between the bottom frame support columns 101 and located above the bottom frame support columns 101;

[0062] The hydraulic jacking device 3 is fixed at the middle position of the fixing plate 104 .

[0063] The bottom frame support column 101 of this embodiment is made of DN50 steel pipe.

[0064] As an expanded implementation, the bottom frame 1 of this embodiment is connected to and slidably engages with the load-bearing frame 2. The bottom frame support columns 101 utilize DN50 steel pipes, providing high support stability and enabling a slidable engagement with the load-bearing frame 2. A mechanical jacking device 3 is positioned between the two, specifically a hydraulic jacking device 3 integrated into the center of the fixed plate 104.

[0065] Based on the structure of the above-mentioned bottom frame 1, the load-bearing frame 2 of this embodiment includes a load-bearing frame support column 201 that cooperates with the bottom frame support column 101. The load-bearing frame support column 201 adopts a DN40 steel pipe, and the lower part of the load-bearing frame support column 201 is embedded in the bottom frame support column 101.

[0066] In order to achieve sliding cooperation with the bottom frame support column 101, the load-bearing frame support column 201 of the load-bearing frame 2 of this embodiment adopts a DN40 steel pipe, which is inserted into the load-bearing frame support column 201 and slides up and down under the drive of the hydraulic jacking device 3.

[0067] The main body of the hydraulic jacking device 3 of this embodiment is assembled and fixed to the fixing plate 104 by fixing bolts 301 ; the driving end of the hydraulic jacking device 3 is connected to the bottom of the bearing plate 202 .

[0068] In addition, as a preferred embodiment, the stroke of the hydraulic jacking device 3 of this embodiment needs to be smaller than the length of the load-bearing frame support column 201 to prevent the load-bearing plate 202 from falling off due to human error.

[0069] To expedite the return of the bottom frame 1 and the load-bearing frame 2 after lifting, a reset assembly is provided between the bottom frame 1 and the load-bearing frame 2. Specifically, the reset assembly comprises two reset springs 4 connected between the fixed plate 104 and the load-bearing plate 202.

[0070] Preferably, the control mechanism of the hydraulic jacking device 3 of this embodiment is provided on the bottom plate 103;

[0071] Among them, the control mechanism of this embodiment includes a hydraulic station 302; and a lifting oil pipe 304 and a reset oil pipe 305 connected to the hydraulic station 302, and the lifting oil pipe 304 and the reset oil pipe 305 are respectively connected to the corresponding interfaces of the hydraulic jacking device 3; the hydraulic station 302 has a reversing valve 303.

[0072] First, this embodiment further introduces the composition of the hydraulic jacking device 3, which provides hydraulic oil to the hydraulic jacking device 3 through the hydraulic station 302, and uses the reversing valve 303 to switch the jacking oil pipe 304 and the reset oil pipe 305, thereby realizing the lifting and lowering of the driving end of the hydraulic jacking device 3.

[0073] In order to further cooperate with the lifting limit of the hydraulic jacking device 3 , the lifting limit mechanism 5 of this embodiment includes a limiter 501 and a pull wire 502 connected between the limiter 501 and the bearing plate 202 .

[0074] The limiter 501 of this embodiment is connected to the controller through a control circuit 503, and is connected to a pull wire 502. The pull wire 502 is in a non-stretched state when not in the lifting state. Once the device is started, the driving end of the hydraulic jacking device 3 lifts the load-bearing plate 202. At this time, the pull wire 502 will rise along with the load-bearing plate 202. When it rises to a specified height, it triggers a limit switch or uses the pull wire to trigger other switches to indicate that it has been lifted to the maximum height. In this way, the lifting height of the hydraulic jacking device 3 is constrained by the lifting limit mechanism 5, which plays a safety protection role. In addition, when actually wiring, a hole can be drilled on the fixed plate 103 to allow the pull wire 502 to pass through, or it can be bypassed from the side of the fixed plate 104 to achieve wiring. The wiring method is not unique.

[0075] In the above technical solution, the utility model provides an electric safety operation device for quickly replacing a fixture crane carriage, which has the following beneficial effects:

[0076] The operating device of the utility model can realize the lowering, moving, lifting and supporting of the truck, avoiding manual handling and manual dragging, reducing labor intensity, improving operating efficiency and reducing safety risks.

[0077] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
