Abstract
Description
Technical Field
[0001] The invention relates to a drainage structure in a railway turnout close contact detector, in particular to a design method for the drainage structure of the close contact detector. Background Art
[0002] The railway turnout close contact detector is the main component of the speed-up turnout conversion equipment. The reliability of the close contact detector on track depends on the performance of key components. In the open air environment, the corrosion resistance of various metal parts is subjected to severe tests.
[0003] like Figure 1 As shown, in the existing technology, it is difficult to improve the sealing effect of the square rod. After the seal is aged, water often enters the site and accumulates in the guide sleeve and cannot be discharged, causing the rod to rust.
[0004] Because the distance between the guide sleeve of the detector and the installation base plate is too close, the structural design of the existing drainage rubber plug cannot be integrated, but the demand of on-site users for improving the drainage structure at the guide sleeve is increasing day by day. Summary of the invention
[0005] The invention provides a design method for a drainage structure of a dense detector capable of discharging accumulated water in a guide sleeve out of the dense detector.
[0006] The specific technical scheme of the present invention is: the present invention relates to a design method of a close fit detector drainage structure, which is characterized in that: it includes a guide sleeve and a close fit detector indicating rod, the close fit detector indicating rod passes through the guide sleeve, a drainage groove is opened at the bottom of the guide sleeve, and a guide rope is embedded inside the drainage groove. The guide rope is a corrosion-resistant guide rope, and the guide rope is clamped between the bottom end face of the guide sleeve and the end face of the bottom shell; when the close fit detector indicating rod is in reciprocating motion, the accumulated water in the guide sleeve will pass through the drainage groove and be discharged along the guide rope.
[0007] A drainage groove or a drainage bolt has a guide rope embedded inside the drainage bolt. The guide rope is a corrosion-resistant guide rope, and the guide rope is clamped between the bottom end surface of the guide sleeve and the end surface of the bottom shell. When the close fit checker indicating rod is in reciprocating motion, the accumulated water in the guide sleeve will be discharged along the guide rope through the drainage bolt.
[0008] Furthermore, the drainage groove or the drainage bolt is located in the middle of the funnel-shaped bottom. A funnel-shaped drainage groove is provided on the bottom surface of the guide sleeve, and the drainage bolt is installed at the bottom of the funnel-shaped drainage groove.
[0009] The interference fit between the guide rope and the drain groove prevents fine dust from entering the machine through the drain groove.
[0010] A U-shaped drainage pad is placed at the front opening of the guide sleeve with the opening of the U-shaped drainage pad facing downward. Before the indicating rod enters the guide sleeve, the U-shaped drainage pad will first scrape off the water on the indicating rod, and since the bottom of the drainage pad is open, the water stains will flow to the ground along the gap of the drainage pad, thus playing a drainage role.
[0011] The advantages of the present invention are: 1. The present invention provides a drainage groove on the lower end surface of the guide sleeve and installs a guide rope between the guide sleeve and the bottom shell. This design not only takes sealing performance into consideration, but also realizes drainage function.
[0012] 2. For drainage structures in narrow spaces, considering the convenience of disassembly and assembly, grooves are cut at the bottom, and the guide rope can be installed by disassembling and assembling the guide sleeve mounting bolts.

[0016] In order to further explain the technical means and effects adopted by the invention to achieve the predetermined purpose, the specific implementation methods, structural features and effects of the invention are described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 2 , Figure 3 and Figure 4As shown, the present invention relates to a design method for a close-fitting detector drainage structure, which is characterized in that: it includes a guide sleeve 1 and a close-fitting detector indicating rod 7, the close-fitting detector indicating rod 7 passes through the guide sleeve 1, a drainage groove 3 is opened at the bottom 2 of the guide sleeve 1, and a guide rope 4 is embedded in the drainage groove 3. The guide rope 4 is a corrosion-resistant guide rope, and the guide rope 4 is clamped between the bottom end face 5 of the guide sleeve 1 and the end face 6 of the bottom shell; when the close-fitting detector indicating rod 7 is in the reciprocating motion process, the accumulated water in the guide sleeve 1 will pass through the drainage groove 3 and be discharged along the guide rope 4.
[0018] like Figure 5a As shown, the drainage groove 3 or the drainage bolt 9 has a guide rope 4 embedded inside the drainage bolt 9. The guide rope 4 is a corrosion-resistant guide rope, and the guide rope 4 is clamped between the bottom end surface 5 of the guide sleeve 1 and the bottom shell end surface 6. When the close contact inspection device indicates that the rod 7 is in the reciprocating motion, the accumulated water in the guide sleeve 1 will be discharged along the guide rope through the guide rope 4 in the drainage bolt 9.
[0019] Further, such as Figure 5b As shown, the drainage groove 3 or the drainage bolt 9 is located in the middle of the bottom of the funnel-shaped structure. The funnel-shaped drainage groove 3 is provided on the bottom surface of the guide sleeve 1, and the drainage bolt 9 is installed at the bottom of the funnel-shaped drainage groove 3. Compared with the guide rope 4 structure, this embodiment is more difficult to modify the guide sleeve 1, and the drainage bolt 9 needs to be specially made. When installing the drainage bolt 9, the guide sleeve 1 needs to be completely disassembled, which is not conducive to on-site modification. Therefore, this embodiment is not preferred, but its drainage effect is better.
[0020] Because the detector guide sleeve 1 is very close to the installation base plate 8, it is basically impossible to install and open and close the waterproof and breathable structure. If the sealing performance of the drainage structure at the guide sleeve 1 is also considered, it is necessary to design an interference fit between the guide rope 4 and the drainage groove 3 so that fine dust cannot enter the machine through the drainage groove 3.
[0021] Furthermore, if the guide sleeve 1 needs a period of disassembly and repair on site, and the problem of water ingress to the detector cannot be solved immediately, an alternative implementation such as Figure 6 As shown: a U-shaped drainage pad 10 is inserted into the front side opening of the guide sleeve 1, that is, a U-shaped drainage pad 10 is placed at the front side opening of the guide sleeve 1, and the mouth of the U-shaped drainage pad 10 faces downward. The advantage of this installation is that before the indicating rod 7 enters the guide sleeve 1, the U-shaped drainage pad 10 will first scrape off the water on the indicating rod 7, and because the bottom of the drainage pad 10 is in an open state, the water stains will flow to the ground along the gap of the drainage pad 10, thereby playing a drainage role.
[0022] The drainage structure of the present invention achieves drainage function by improving the existing guide sleeve 1 and using corrosion-resistant drainage structures such as guide ropes 4 clamped in small holes to drain the accumulated water in the guide sleeve 1 without adding additional parts. The guide rope 4 can achieve the diversion function and is suitable for the material and form of the open air environment. The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
[0023] For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
