Abstract
Description
Technical Field
[0001] This utility model belongs to the field of processing tooling technology, and more specifically, it relates to a seepage layer tooling for a high-speed railway bridge pier hanging fence support. Background Technology
[0002] High-speed railway bridge pier hanging fence supports are a type of safety protection facility used in the construction of high-speed railway bridges. They are mainly installed on the edge of the bridge or around the piers to protect the safety of construction workers, prevent tools and materials from falling, and in some cases, also to beautify the appearance of the bridge. However, the supports are prone to corrosion after long-term use, so zinc-nickel infiltration is required during the production process.
[0003] Current zinc-nickel corrosion protection technology uses a rotary drum furnace to process the diffusion layer. The process involves placing the workpiece to be coated into a special fixture, then into a furnace chamber filled with diffusion agent, and finally rotating it at a constant speed for heating. Because of the rotation, the workpiece inside the furnace tumbles continuously, and multiple supports collide with each other, leading to poor diffusion layer formation and, in severe cases, product damage.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a seepage layer tooling for the support of the railing of high-speed railway bridge piers, in order to achieve a more practical purpose. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a seepage layering tooling for high-speed railway bridge pier hanging fence supports, which solves the problem that multiple supports collide with each other inside the furnace during roller seepage layering of high-speed railway bridge pier hanging fence supports, resulting in poor seepage layering and easy damage.
[0006] The purpose and effectiveness of this utility model for the seepage layer tooling of the high-speed railway bridge pier hanging fence support are achieved by the following specific technical means:
[0007] A permeation tooling for a high-speed railway bridge pier hanging fence support includes a base plate and a rear fixing plate. A front fixing plate is provided on the base plate. Both the rear fixing plate and the front fixing plate are provided with multiple corresponding slots. The front fixing plate and the rear fixing plate are connected by pins passing through the corresponding slots. Multiple pads are distributed vertically on the front fixing plate.
[0008] Furthermore, a foot block is provided on the base plate, and the foot block abuts against the outer side of the bottom of the rear fixing plate.
[0009] Furthermore, a pad strip is provided on the base plate.
[0010] Furthermore, the pin block includes a pressure plate, which passes through the slots of the front and rear fixed plates and abuts against the bracket. One end of the pressure plate is provided with a limiting plate, and the other end is provided with multiple through holes.
[0011] Furthermore, the base plate has multiple drainage holes.
[0012] Furthermore, both the front fixing plate and the rear fixing plate are provided with multiple corresponding openings.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The bracket is fixed by the clamping of the front and rear fixing plates in the tooling, which reduces the shaking of the bracket in the furnace. At the same time, each pad can support the adjacent brackets, which can play an isolation role and prevent overlapping brackets from colliding with each other. In addition, the bracket and the tooling are placed in the furnace as a whole and rotated, and the multiple brackets do not fall apart, effectively protecting the product. Attached Figure Description

[0025] Example:
[0026] As attached Figure 1 To be continued Figure 5 As shown:
[0027] This utility model provides a seepage layer tooling for a high-speed railway bridge pier hanging fence support, including a base plate 3 and a rear fixing plate 2. A front fixing plate 1 is provided on the base plate 3. Both the rear fixing plate 2 and the front fixing plate 1 have a plurality of corresponding slots 102. After the support is overlapped, it is clamped in the front fixing plate 1 and the rear fixing plate 2. The front fixing plate 1 and the rear fixing plate 2 are connected by pins 6 passing through the corresponding slots 102 to complete the fixation. The clamped whole is placed in a furnace for seepage layer treatment.
[0028] In addition, multiple pads 103 are vertically distributed on the front support plate 1. The pads 103 can support the adjacent supports and play an isolation role to prevent the overlapping supports from colliding with each other. When one end of the pad 103 contacts one of the supports, there is a gap between the other end and the other support, so that the penetrant can contact every position of the support during the rotation of the support and the tooling in the furnace, preventing the support and the tooling from sticking together and forming a layer that cannot be penetrated.
[0029] In this embodiment, a foot block 105 is provided on the base plate 3. The foot block 105 abuts against the outer side of the bottom of the rear fixed plate 2 to enhance the overall stability of the connection between the rear fixed plate 2, the front fixed plate 1, and the base plate 3. A pad strip 104 is also provided on the base plate 3 to increase the gap between the bracket and the base plate 3. At the same time, multiple drainage holes 5 are provided on the base plate 3 so that the seepage agent can contact the bracket at the bottom.
[0030] Both the front fixed plate 1 and the rear fixed plate 2 have multiple corresponding drain holes 4. The height of the drain hole 4 is greater than the height of the slot 102. It can be used as a slot 102 and also allows the penetrant to pass through the front fixed plate 1 and the rear fixed plate 2.
[0031] The pin 6 includes a pressure plate 303, which passes through the slot 102 of the front fixed plate 1 and the rear fixed plate 2 and abuts against the bracket. One end of the pressure plate 303 is provided with a limiting plate 301, and the other end is provided with multiple through holes 302. The limiting plate 301 restricts the depth of the pressure plate 303 passing through the slot 102, while the through holes 302 on the extended part can reduce the obstruction of the penetrant.
[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
