Therefore, it is necessary to develop and design a new wheel expanding device.
Disclosure of Invention
The utility model aims to avoid the shortcoming and the weak point that exist among the above-mentioned prior art, provide not only design structure scientific and reasonable, can prevent that the machine during operation is impaired, move safe and reliable again, have a novel wheel device that rises of maintenance, convenient to use of being convenient for moreover.
The utility model aims at adopting the following technical scheme to realize: a novel wheel expanding device comprises an electro-hydraulic push rod (1), a swing frame (2), a connecting frame (5), a push rod base (3), a pull rod assembly (8), a base (11), a connecting rod I (4), a connecting rod II (6), a swing arm I (9), a swing arm II (10) and a clamping opening (12), wherein the electro-hydraulic push rod (1) is installed on the push rod base (3); swing frame (2) middle part and push rod base (3) are articulated and round the axle swing on push rod base (3), the one end and the electricity liquid push rod (1) head of swing frame (2) are articulated, the other end and the connecting rod (4) one end of swing frame (2) are articulated, every of connecting rod (4) the other end and one of them link (5) one end articulated, every the link (5) other end passes through the axle and is connected with base (11), connect through connecting rod two (6) between two link (5), two pull rod assembly (8) one end articulates respectively in two link (5) middle parts, every the other end of pull rod assembly (8) is articulated with the one end of swing arm one (9), the other end and swing arm two (10) one end of swing arm (9) are articulated, the other end of swing arm two (10) articulates on pressing from both sides mouth (12).
Furthermore, the swing frame (2) is in a triangular fork shape.
The principle of the utility model is as follows: the electro-hydraulic push rod stretches out and retracts, the connecting rod is pulled through the swinging frame, the connecting rod pulls the pull rod assembly to move horizontally, the swinging arms at the two ends of the base swing along the fixed points, and the swinging arms drive the clamping openings to open and retract. Wherein the pull rod assembly is internally provided with a spring; the spring can adjust the rigidity by adjusting the gasket, thereby changing the expansion force of the wheel expander.
Compared with the prior art, the utility model has the advantages of it is following:
1. the electro-hydraulic push rod is used for driving, compared with hydraulic driving, the cost is low, the maintenance is simple, the occupied space is small, and the original foundation is not required to be damaged;
2. slopes at two ends of the clamping rail can enter the vehicle in an opening state of the wheel expanding device, and the vehicle and equipment are not damaged;
3. the wheel expanding device is of a split structure, the main structure is fixed between two rails of a railway line, and the driving device can be installed on a foundation outside the railway line, so that the wheel expanding device is compact in structure and simple and convenient to install, disassemble and assemble.

fig. 2 is a schematic top view of an open position of an embodiment of the present invention;
fig. 3 is a left side view of the particular embodiment.
In the figure: 1. an electro-hydraulic push rod; 2. a swing frame; 3. a push rod base; 4. a first connecting rod; 5. a connecting frame; 6. a second connecting rod; 7. a shaft; 8. a drawbar assembly; 9. a first swing arm; 10. a second swing arm; 11. a base; 12. and (4) clamping the opening.
Detailed Description
As shown in fig. 1-3, the novel wheel expanding device is a novel wheel expanding device, and comprises an electro-hydraulic push rod 1, a swing frame 2, a connecting frame 5, a push rod base 3, a pull rod assembly 8, a base 11, a first connecting rod 4, a second connecting rod 6, a first swing arm 9, a second swing arm 10 and a clamping opening 12, wherein the electro-hydraulic push rod 1 is installed on the push rod base 3; swing frame 2 middle part and the push rod base 3 of triangle fork type are articulated and round the axle swing on the push rod base 3, the one end of swing frame 2 is articulated with 1 head of electricity liquid push rod, the other end and the 4 one ends of connecting rod of swing frame 2 are articulated, every of the other end and 5 one end of one of them link 5 other end of link is connected with base 11 through the axle, connect through two 6 connecting rods between two links 5, two pull rod assembly 8 one ends articulate respectively at 5 middle parts of two links, every pull rod assembly 8's the other end is articulated with the one end of swing arm 9, the other end and the two 10 one ends of swing arm 9 are articulated, the other end of two 10 swing arms articulates on pressing from both sides mouthful 12.
The working principle is as follows: when the electro-hydraulic push rod 1 works, the swing frame 2 is driven to do rotary motion, when the electro-hydraulic push rod 1 extends to the full stroke (the position shown in figure 2), the push rod can push the swing frame 2 to move together with the connecting rod I4, the connecting rod I4 pulls all mechanisms of a main body of the wheel expanding device to swing, and finally the swing arm II 10 pulls the clamping opening 12 to swing. When the clamping opening 12 needs to be retracted, the electro-hydraulic push rod 1 retracts to the original position (the position shown in figure 1), and the clamping opening 12 is restored under the action of the pull rod assembly 8.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
