Description

Technical Field

[0001] The invention relates to the technical field of embedded steel plate processing, and more specifically to a multi-element powder co-infiltration tooling for embedded steel plates of contact networks for high-speed railways. Background Art

[0002] The overhead contact network is a high-voltage transmission line that is set up in a zigzag shape above the rails in an electrified railway and is used by the pantograph to draw current. The overhead contact network consists of contact suspension, support device, positioning device, pillars and foundation. The embedded parts of the overhead contact network foundation for high-speed railways are embedded in the beam at the corresponding position, and the part of the foundation above the beam surface is constructed together with the vertical wall of the beam after the beam is erected.

[0003] With the enhancement of comprehensive national strength, the construction of concrete bridges such as highways and railways in my country has been greatly accelerated, and the quality and durability requirements of bridge-related steel parts have also been gradually improved. At present, the number of concrete structure metal embedded parts, bolt fasteners, etc. using multi-element metal powder co-penetration anti-corrosion treatment is increasing. The principle is to use high-temperature atomic diffusion and mechanical collision to form an anti-corrosion layer on the surface of the workpiece with multi-element metal powder. In this way, due to the introduction of other metal elements, the anti-corrosion layer is composed of similar multiple alloys, thereby improving the anti-rust performance of the penetration layer.

[0004] The utility model patent with the patent application publication number CN214782088U discloses a new type of angle steel multi-element alloy co-infiltration special tooling, including a mounting structure, a bracket body and a workpiece, wherein the mounting structure is provided with two groups, the bracket body is provided with two, and the two bracket bodies are both installed at the two groups of mounting structures, and the upper end surfaces of the two bracket bodies are provided with a plurality of inclined grooves inclined at 45°, and the inclined directions of the plurality of inclined grooves are consistent, and the spacing between adjacent inclined grooves is the same, and the workpiece is provided with a plurality of, and the bottoms of the plurality of workpieces are respectively clamped in the inclined grooves inside the two bracket bodies, and the mounting structure includes a connecting bracket and a limiting steel pipe, and the connecting bracket and the limiting steel pipe are both provided with two. The utility model has a simple structure and is easy to use, and can effectively avoid collision or mutual shielding between workpieces, which causes uneven thickness of the infiltration layer, and even causes serious problems such as scratches and shedding of the infiltration layer on the surface of the workpiece, and has high practicality.

[0005] However, in actual use, although the workpiece can be isolated and fixed to avoid scratches, the workpiece is fixed and cannot be combined with the multi-element metal powder, which will cause a penetration layer gap on the surface of the workpiece, thereby reducing the overall anti-corrosion performance of the workpiece, especially the use of embedded parts, which will lead to a reduction in the service life of the embedded parts. Therefore, a multi-element powder co-infiltration tooling for embedded steel plates of contact networks for high-speed railways is proposed. Summary of the invention

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] As attached Figure 1-11 The multi-element powder co-infiltration tooling for the embedded steel plate of the contact network for high-speed railway shown in the figure comprises a top plate 1, two lifting ears 2 are symmetrically welded on the top plate 1, a plurality of legs 3 are symmetrically installed at the bottom end of the top plate 1, and a support block 4 is installed on each of the legs 3. The top of each of the support blocks 4 is jointly supported by a support device 5, and the top of the support device 5 is matched with a pressing device 6 connected to the top plate 1;

[0049] The supporting device 5 comprises a lower supporting plate 51, a first supporting mechanism 52 and a second supporting mechanism 53. The lower supporting plate 51 is bolted to the top of the supporting block 4. The bottom end of the first supporting mechanism 52 is inserted into the supporting block 4, and the top end of the first supporting mechanism 52 is connected to the top plate 1. The bottom end of the second supporting mechanism 53 is inserted into the supporting block 4. The bottom end of the second supporting mechanism 53 is vertically plugged with the first supporting mechanism 52, and the top end of the second supporting mechanism 53 is connected to the top plate 1.

[0050] The pressing device 6 includes an upper pressing plate 61, a first pressing mechanism 62 and a second pressing mechanism 63. The upper pressing plate 61 is arranged in parallel at the top of the lower support plate 51, and the upper pressing plate 61 and the lower support plate 51 are connected at both sides. The bottom end of the first pressing mechanism 62 is plugged into the top of the upper pressing plate 61, and the top of the first pressing mechanism 62 is connected to the top plate 1. The bottom end of the second pressing mechanism 63 is plugged into the top of the upper pressing plate 61, and the second pressing mechanism 63 and the second pressing mechanism 63 are vertically plugged and matched, and the top of the second pressing mechanism 63 is connected to the top plate 1.

[0051] The lower support plate 51 and the upper pressing plate 61 have the same structure, the first support mechanism 52 and the first pressing mechanism 62 have the same structure, and the second support mechanism 53 and the second pressing mechanism 63 have the same structure.

[0052] In a specific implementation, multi-element metal powder is laid on the support device 5, and then the embedded steel plate is evenly placed on the support device 5, which is supported by the first support mechanism 52 and the second support mechanism 53, and the multi-element metal powder is laid on the top of the laid embedded steel plate, and then the bolt rod 8 is adjusted to adjust the position of the pressing device 6 on the top, so that the pressing device 6 is lowered, and when the pressing device 6 is lowered, the first pressing mechanism 62 and the second pressing mechanism 63 in the pressing device 6 are synchronously lowered, so that the first pressing mechanism 62 and the second pressing mechanism 63 are pressed on the top of the embedded steel plate, so that each laid embedded steel plate is clamped, and then the lifting ear 2 is lifted to move the entire tooling with the embedded steel plate placed thereon into the oven, and the top plate 1 cooperates to seal the oven, so that the embedded steel plate with the multi-element metal powder on the inner surface of the tooling is baked, so as to perform the co-infiltration operation;

[0053] During the co-infiltration operation of the embedded steel plate, the bottom end of the first supporting mechanism 52 descends and the second pressing mechanism 63 rises, so that the second supporting mechanism 53 and the first pressing mechanism 62 cooperate to clamp the embedded steel plate, and then, the bottom end of the first supporting mechanism 52 rises and the second pressing mechanism 63 descends. After the bottom end of the first supporting mechanism 52 rises and the second pressing mechanism 63 cooperates to clamp the embedded steel plate again, the second supporting mechanism 53 descends and the first pressing mechanism 62 rises, and this cycle is repeated to continuously change the clamping point of the embedded steel plate. In the process of changing the clamping point, the embedded steel plate can remain fixed, so that the multi-element metal powder can contact various positions of the embedded steel plate, thereby ensuring that an overall co-infiltration layer can be formed on the surface of the embedded steel plate, thereby avoiding the generation of missing corners, thereby improving the rust-proof performance of the embedded steel plate after the co-infiltration is completed.

[0054] As attached Figure 2 As shown, fixed blocks 7 are welded on both sides of the supporting device 5 and the pressing device 6, and a bolt rod 8 is connected between the two fixed blocks 7 on the same side. A pressing nut and a supporting nut are sleeved on the top of the bolt rod 8. The pressing nut is arranged on the top of the fixed block 7 on one side of the pressing device 6, and the supporting nut is arranged at the bottom of the fixed block 7.

[0055] During specific implementation, the lowering position of the pressing device 6 can be adjusted by the support nut on the bolt rod 8, thereby adjusting the distance between the pressing device 6 and the support device 5, so that the embedded steel plates of different thicknesses and shapes can be clamped conveniently, and the embedded steel plates can be fixed by tightening the pressing nut.

[0056] As attached Figure 5 As shown, the first supporting mechanism 52 includes two first electric telescopic rods 5201, and the two first electric telescopic rods 5201 are symmetrically installed on the top plate 1;

[0057] Two first connecting components 5202, one end of each of the first connecting components 5202 is connected to the bottom end of the corresponding first electric telescopic rod 5201;

[0058] There are multiple first supporting components 5203 , each of which is evenly connected between two first connecting components 5202 , and each of which is inserted into the lower supporting plate 51 .

[0059] In specific implementation, by extending and retracting the first electric telescopic rod 5201, the first connecting component 5202 can be raised and lowered accordingly, so that each first support component 5203 can be raised and lowered accordingly, so that each first support component 5203 can be supported out from the lower support plate 51, or stored in the lower support plate 51. When the first support component 5203 descends, the top of the first support component 5203 is flush with the top surface of the lower support plate 51, preventing multi-element metal powder from entering the lifting groove 6102.

[0060] As attached Figure 6 As shown, the first connecting assembly 5202 includes a first connecting plate 5202a, and one end of the first connecting plate 5202a is connected to the corresponding first electric telescopic rod 5201;

[0061] A plurality of first slots 5202b, each of which is evenly arranged on one side of the first connecting plate 5202a, each of which is a right-angle slot, and the bottom of one end of each first supporting assembly 5203 is respectively plugged into the corresponding first slot 5202b;

[0062] Two first locking rods 5202c, the two first locking rods 5202c pass through each first slot 5202b and are connected to each first supporting assembly 5203.

[0063] During specific implementation, the first connecting plate 5202a can be lifted and lowered by lifting the first electric telescopic rod 5201, so that the first supporting assembly 5203 connected by the first locking rod 5202c in each first slot 5202b can be lifted and lowered accordingly. The first slot 5202b is a right-angle slot and can cooperate with the corner at the bottom of one end of the first supporting assembly 5203, thereby improving the installation fit and reducing the force exerted on the first locking rod 5202c, thereby reducing the wear on the connection of the first supporting assembly 5203 and improving the overall service life.

[0064] As attached Figure 7 As shown, the first supporting assembly 5203 includes a horizontal plate 5203a, and both ends of the horizontal plate 5203a are respectively inserted into corresponding first slots 5202b and connected to corresponding first locking rods 5202c;

[0065] Two side plates 5203b, the two side plates 5203b are symmetrically arranged at two ends of the horizontal plate 5203a;

[0066] A plurality of support bars 5203c are evenly arranged on the horizontal plate 5203a between two side plates 5203b.

[0067] In a specific implementation, the two ends of the horizontal plate 5203a are inserted into the first slot 5202b and connected to the first locking rod 5202c, so that when the first connecting plate 5202a is raised or lowered, the horizontal plate 5203a can be raised or lowered synchronously, so that the two side plates 5203b and multiple support bars 5203c are raised or lowered accordingly, so that each support bar 5203c can support the embedded steel plate, or when it is lowered, the support point here is eliminated, so that the multi-element metal powder at the support point can fit with the embedded steel plate, thereby performing co-infiltration.

[0068] As attached Figure 8 As shown, the second supporting mechanism 53 includes a second electric telescopic rod 5301, and the top end of the second electric telescopic rod 5301 is connected to the top plate 1;

[0069] A second connecting component 5302, which is installed at the bottom end of the second electric telescopic rod 5301;

[0070] A plurality of second supporting components 5303 , each of the second supporting components 5303 is evenly connected to one side of the second connecting component 5302 .

[0071] In specific implementation, by extending and retracting the second electric telescopic rod 5301, the second support assembly 5303 connected to the second connecting assembly 5302 can be raised and lowered synchronously, so that the second support assembly 5303 can be pushed out from the lower support plate 51 or retracted into the lower support plate 51, thereby cooperating with the ups and downs of the first support assembly 5203, so that the support point can be changed.

[0072] As attached Fig. 9 As shown, the second connecting assembly 5302 includes a second connecting plate 5302a, and the second connecting plate 5302a is installed at the bottom end of the second electric telescopic rod 5301;

[0073] A plurality of second slots 5302b, each of which is evenly arranged on one side of the second connecting plate 5302a, each of which is a right-angle slot, and the bottom of one end of each second supporting assembly 5303 is respectively plugged into the corresponding second slot 5302b;

[0074] Two second locking rods 5302c, the two second locking rods 5302c pass through each second slot 5302b and are connected to each second supporting assembly 5303.

[0075] In specific implementation, by extending and retracting the second electric telescopic rod 5301, the second connecting plate 5302a can be raised and lowered, so that the second support assembly 5303 inserted in the second slot 5302b and connected to the second locking rod 5302c can be raised and lowered. Moreover, by setting the second slot 5302b as a right-angle slot, the coordination of the bottom connection at one end of the second support assembly 5303 can be improved, thereby ensuring that the second support assembly 5303 can be stably raised and lowered vertically.

[0076] As attached Fig.10 As shown, the second support assembly 5303 includes a support plate 5303a, one end of which is inserted into the corresponding second slot 5302b and connected to the two second locking rods 5302c;

[0077] A plurality of through slots 5303b are evenly arranged on the support plate 5303a, and the first support assembly 5203 is inserted into each through slot 5303b.

[0078] During specific implementation, one end of the support plate 5303a is inserted into the second slot 5302b and connected to the two second locking rods 5302c, so that the support plate 5303a can be raised and lowered synchronously with the second connecting plate 5302a, so that the support plate 5303a can alternately support the embedded steel plate with the support bar 5203c, thereby cyclically changing the clamping point where the embedded steel plate is fixed. Therefore, during the entire co-infiltration process, the embedded steel plate is equivalent to being in a suspended fixed state, thereby ensuring that the embedded steel plate forms a co-infiltration layer as a whole, avoiding the formation of gaps in the co-infiltration layer, and thus improving the corrosion and rust resistance of the embedded steel plate.

[0079] As attached Fig.11 As shown, the upper pressing plate 61 includes a plate body 6101, and the plate body 6101 is connected to the lower supporting plate 51;

[0080] A plurality of lifting slots 6102 are evenly arranged on the plate body 6101 , and two lifting slots 6102 at the edges are connected to a plurality of side slots 6103 .

[0081] In specific implementation, the support bar 5203c and the support plate 5303a are plugged into the lifting groove 6102, so that the lifting groove 6102 is closed, and the side groove 6103 is closed by the side plate 5203b, and the support bar 5203c fills the through groove 5303b, so that during the co-infiltration operation, each support plate 5303a and the support bar 5203c are alternately lifted and lowered, thereby alternately supporting the embedded steel plate, thereby continuously changing the support point, so that each support point can also be alternately exposed, which is convenient for combining with multi-element metal powder, so that after the co-infiltration operation, the outside of the embedded steel plate can be completely wrapped by the co-infiltration layer, thereby improving the anti-corrosion and anti-rust performance of the embedded steel plate.
