Description

Technical Field

[0001] This utility model relates to railway equipment, and in particular to a tooling for installing a contact frame. Background Technology

[0002] The switch machine's contact frame is a key component in the railway turnout control system. It works closely with the switch machine to ensure that trains can safely and accurately switch from one track to another. The main functions of the switch machine's contact frame include: (1) Signal transmission: The contact frame contains a series of electrical contact points (or contacts) that close or open depending on the position of the turnout. In this way, they provide information about the turnout's position to the railway signaling system. For example, a specific set of contacts closes when the turnout points to a straight track, while another set closes when the turnout points to a siding. (2) In addition to electrical functions, the contact frame also provides physical support for the moving parts inside the switch machine. It helps stabilize and position these parts, ensuring that they maintain the correct relative position during operation. (3) Safety assurance: By precisely controlling the position of the turnout and feeding it back to the signaling system, the contact frame ensures the safe operation of trains. If the turnout is not set correctly, the signaling system can prevent trains from entering the path, thus avoiding potential collisions.

[0003] Traditionally, installing a connector rack requires a lot of physical labor, including multiple reverse installations of components. The connector rack itself needs to be moved and repositioned many times, making it a time-consuming and labor-intensive task. Furthermore, the repeated moving of the connector rack can easily cause it to be bumped and damaged. Utility Model Content

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] Combination Figure 1-2 As shown, this utility model provides a tooling 100 for installing a contact bracket, which includes a rotating work platform 10, a contact bracket support block 20, a base 30, and a locking assembly 40. The rotating work platform 10 has a first assembly section 11 in the center, and a plurality of locking holes 12 are provided around the first assembly section 11. These locking holes 12 are distributed on a circumference with the first assembly section 11 as the center, and the number of locking holes 12 is 4-12. In this embodiment, the first assembly section 11 is an assembly hole, and the number of locking holes 12 is 8, evenly distributed on a circumference with the first assembly section 11 as the center. The locking holes 12 are through holes.

[0030] A contact bracket support block 20 is mounted on the rotary work platform 10. The contact bracket support block 20 includes a first protrusion 21 and a second protrusion 22, which are centrally symmetrically arranged at both ends of the rotary work platform relative to the first assembly part 11, with a certain distance between them. The tops of the first protrusion 21 and the second protrusion 22 are fixed to the contact bracket, creating a large gap between the lower surface of the contact bracket and the upper surface of the rotary work platform. This gap provides operating space for reverse mounting of various accessories on the contact bracket. The first protrusion 21 and the second protrusion 22 are integrally formed with the rotary work platform 10 or fixed to the rotary work platform 10 by welding. Figure 1 As shown, the top surfaces of the first protrusion 21 and the second protrusion 22 are provided with a plurality of bolt holes 210 and 220 for mounting the contact bracket.

[0031] The base 30 has a second assembly part 331 at its upper end, which is a convex shaft. A bearing is installed in the assembly hole of the first assembly part 11, and the convex shaft of the second assembly part 331 is assembled into the bearing hole, thereby allowing the rotary work platform 10 to rotate smoothly relative to the base 30 in the horizontal plane.

[0032] Preferably, the rotating work platform 10 does not detach from the base 30 in the height direction. The base 30 has a certain height, which is based on the distance from most people's hands naturally hanging to the ground when standing, so as to be suitable for workers to stand and work, and improve the operating comfort of workers during the installation of accessories on the joint frame. The base 30 includes a base plate 31, an intermediate connecting column 32, and a top plate 33 connected in sequence from bottom to top, and a second assembly part 331 is provided on the top plate 33. The top plate 33 is used to support the rotating work platform 10. The base plate 31 is set on the ground or a working base surface, and the base plate 31 is provided with bolt holes for fixing to the ground or working base surface. The base plate 31 has an enlarged diameter surface relative to the intermediate connecting column 32, so as to ensure that the entire tooling is placed stably on the ground; the top plate 33 has an enlarged diameter surface relative to the intermediate connecting column 32, so that the rotating work platform 10 can rotate more smoothly relative to the base 30. Preferably, the area of ​​the top plate 33 is equal to the area of ​​the largest inscribed circle of the rotating work platform 10.

[0033] A locking assembly 40 is provided on the side wall of the base 30. The locking assembly 40 includes a locking pin 41, which can be operated to move vertically up and down, so that the upper end 411 of the locking pin 41 is inserted into a locking hole 12 of the rotating work platform 10 (e.g., Figure 1 (As shown) The rotating work platform 10 is then fixed relative to the base 30, or it is removed from the locking hole 12 to allow the rotating work platform 10 to rotate freely relative to the base 30. Preferably, when the locking post 41 is inserted into the locking hole 12, its upper end 411 does not protrude from the surface of the rotating work platform 10, so as to avoid occupying the operating space of the operator for reverse installation of accessories.

[0034] A guide cylinder 332 is provided on the lower surface of the top plate 33. The top plate 33 has a through hole corresponding to the upper end of the guide cylinder 332. The guide cylinder 332 is a hollow cylinder. The lower end of the guide cylinder 332 fits around the outside of the locking pin 41, keeping the upper end of the locking pin 41 inside the guide cylinder 332, while the lower end of the locking pin 41 extends outside the guide cylinder 332 (hinged to the connecting rod 46). The upper end 411 of the locking pin 41 can pass through the through hole on the guide cylinder 332 and the top plate 33 and be inserted into a locking hole 12 of the rotary work platform 10 to position the rotary work platform 10. The guide cylinder 332 allows for smoother and more stable up-and-down movement of the locking pin 41. Specifically, as shown... Figure 1 As shown, the locking assembly 40 includes a horizontal shaft 42 located on the lower outer side of the base 40 (near the chassis 31). A rotating sleeve 43 is provided outside the horizontal shaft 42, and a torsion spring is provided between the horizontal shaft 42 and the rotating sleeve 43. The starting end of the operating arm 44 is connected to the outside of the rotating sleeve 43. A pedal 45 is provided at the end of the operating arm 44, and the surface of the pedal 45 is provided with anti-slip points. The lower end of a connecting rod 46 is hinged to the middle part of the operating arm 44, and the upper end of the connecting rod 46 is hinged to the lower end of the locking pin 41.

[0035] During the installation of accessories on the contact frame, see [the following text is incomplete and requires further context]. Figure 3 As shown, when the pedal 45 is stepped on, the operating arm 44 drives the connecting rod 46 to move downwards. The connecting rod 46 pulls the locking pin 41 downwards, and the upper end 411 of the locking pin 41 disengages from a locking hole 12 of the rotating work platform 10, allowing the rotating work platform 10 to return to a state where it can rotate freely. At this time, the rotating work platform 10 can be manually pushed to rotate the contact frame to a position suitable for operation. Then, the operator releases the pedal 45 (see...). Figure 1 Under the reset action of the torsion spring, the rotating sleeve 43 resets, driving the operating arm 44 upward. At this time, the connecting rod 46 moves upward and pushes the locking pin 41 upward. The upper end 411 of the locking pin 41 is inserted into a locking hole 12 of the rotating working platform 10 along the guide tube 332 without protruding to the surface of the rotating working platform 10 (e.g., Figure 1 As shown, the rotating work platform 10 is fixed in a certain position relative to the base, at which point the installation operation of the accessories on the contact frame can be carried out. Therefore, the operation of stepping on the pedal 45 is only required when the rotating work platform 10 needs to be rotated. When installing the contact frame accessories, it is not necessary to step on the pedal 45, and the operator can concentrate on the installation of the contact frame accessories.

[0040] Example 4

[0041] The only difference between this embodiment and embodiments 1, 2, or 3 is that the locking assembly 40 includes a transverse hollow cylinder located on the lower outer side of the base 30 (near the chassis 31). A rotating shaft is installed inside the transverse hollow cylinder, and the outer side of the rotating shaft is connected to the starting end of the operating arm.
