Description
Technical Field
[0001] The utility model relates to the technical field of signal lights, in particular to a detachable rotary lifting base for railway signal lights. Background Art
[0002] Railway signal lights are important equipment on railways. They command train operation and shunting operations through different light displays to ensure railway transportation safety and improve transportation efficiency. They are connected to the signal mechanical room through cables, receiving computer instructions and at the same time feeding back information to the dispatching centralized command system in a timely manner. The basic colors of railway signal lights include red, yellow, and green. Through different combinations of these colors, commands such as deceleration, passing, and departure are conveyed to the driver. In addition to the basic red, yellow, and green lights, there are also some special signal displays. For example, two yellow lights indicate that the train is allowed to enter the station through the lateral position of the turnout to prepare for stopping, while two green lights indicate that the train is allowed to depart from the station and head for a secondary line. The setting of these signal lights aims to guide train operation and ensure the safety and efficiency of railway transportation.
[0003] However, the current automation level of railway signal lights is relatively low and still cannot meet the requirements of modern railway transportation. The orientation of existing railway signal lights is fixed. With the increasing number of new railway lines, the required signal lights are gradually increasing. Existing railway signal lights can only meet the complex line requirements by increasing the installation quantity of railway signal lights. Existing railway signal lights are divided into two types: high-position signal lights and low-position signal lights, with different functions. Therefore, multiple railway signal lights need to be installed on a railway line. The light box of existing railway signal lights cannot be disassembled. Because of its very important existence on the railway, and railways are generally built in relatively remote areas, the maintenance of signal lights is difficult. It is impossible to carry out replacement maintenance or maintenance, and standby signal lights need to be installed additionally, which easily leads to an excessive number of signal lights installed, limited installation positions, and time-consuming and laborious maintenance and inspection.

[0022] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] A disassembly structure 4 is provided. The signal light box 5 is fixed to the top end of the lifting structure 3 via the disassembly structure 4. The signal light box 5 performs rotational and lifting movements via the rotational structure 2 and the lifting structure 3. The bottom box 1 includes a box body 11, a box door 12 and a support 13. The box body 11 is the protective housing of the base. A column hole 111 is provided at the center of the top of the box body 11. The top end of the rotational structure 2 is welded to the lifting structure 3 via the column hole 111. The box body 11 is hinged to the box door 12. The box door 12 is provided on the front of the bottom box 1. The box door 12 can be opened to facilitate the maintenance or inspection of the rotational structure 2 inside the box body 11. The support 13 is fixed inside the box body 11. The seat body 131 of the support 13 is provided in the middle part of the box body 11. The seat feet 132 of the support 13 are provided at the left and right ends of the seat body 131. The support 13 is fixed to the bottom surface inside the box body 11 via the seat feet 132. The support 13 is used to support the weight of the overall structure. A shaft hole 133 is provided at the center of the seat body 131. The rotational structure 2 passes through the shaft hole 133, enabling the support 13 to play a supporting role without affecting the operation of the rotational structure 2. See specifically Figure 1 , Figure 2 .
[0024] The rotating structure 2 includes a rotating motor 21 and a rotating column 22. The bottom end of the rotating motor 21 is placed on the bottom surface of the box body 11. The rotating motor 21 is arranged between two pedestal feet 132. The bottom of the seat body 131 is threadedly connected to the rotating motor 21, and a part of the weight of the motor is supported by the seat body 131. The rotating column 22 is connected to the rotating motor 21 by bearings. The rotating column 22 rotates on the top surface of the support 13 through the rotating motor 21. The top of the rotating column 22 is welded to the lifting structure 3, and the rotation of the rotating column 22 drives the lifting structure 3 to rotate. The rotating motor 21 includes a machine body 211, a fixing plate 212 and a rotating shaft 213. The machine body 211 is placed inside the box body 11. The fixing plate 212 is welded to the edge of the top of the machine body 211. The fixing plate 212 is threadedly connected to the bottom of the seat body 131. The machine body 211 is fixed to the bottom of the seat body 131 through a threaded plate, fixing the top of the machine body 211, avoiding all the gravity pressing downwards, and preventing the displacement of the machine body 211 caused by the influence of rotation. The central part of the machine body 211 is connected to the rotating shaft 213. The rotating shaft 213 passes through the shaft hole 133 and is connected to the bottom end of the rotating column 22 by bearings. The machine body 211 controls the rotation of the rotating shaft 213, and the rotating shaft 213 is connected to the rotating column 22 to drive the rotating column 22 to rotate. The rotating column 22 includes a column body 221, rollers 222 and balls 223. The column body 221 is connected to the rotating shaft 213. The rollers 222 are circumferentially arranged on the bottom surface of the column body 221. The rollers 222 assist the column body 221 to rotate on the top surface of the support 13. Since the column body 221 bears the weight of the signal lamp box 5 and the lifting structure 3, the rotational friction between the bottom of the column body 221 and the top of the seat body 131 is relatively large. The rollers 222 can avoid the generation of friction, enabling the rotating shaft 213 to easily drive the column body 221 to rotate. The top end of the column body 221 passes through the column hole 111 and is welded to the bottom end of the lifting structure 3. The column body 221 is welded to the lifting structure 3 through the column hole 111. The balls 223 are circumferentially arranged at the top end of the side of the column hole 111. The top end of the column body 221 rotates in the column hole 111 through the balls 223. The balls 223 between the column body 221 and the column hole 111 prevent friction from occurring on the side of the column body 221 in the column hole 111, and can rotate easily through the control of the motor, thereby changing the orientation of the signal lamp box 5, providing signal instructions for the intricate multiple railway lines, and reducing the number of installed signal lamps.The lifting structure 3 includes a sliding seat 31, a lifting motor 32, a guide sleeve 33, a push rod 34 and a connecting seat 35. The bottom surface of the sliding seat 31 is welded to the top surface of the column 221, and the sliding seat 31 is driven by the column 221 to turn. The lifting motor 32 and the guide sleeve 33 are connected to the top of the sliding seat 31. The push rod 34 is slidably connected in the guide sleeve 33. The lifting structure 3 converts the rotational motion of the motor into the linear reciprocating motion of the push rod 34 to achieve the effect of lifting motion. The top end of the push rod 34 is welded with a connecting seat 35, and the connecting seat 35 is driven by the push rod 34 to make a lifting motion. The connecting seat 35 is used to connect the signal lamp box 5, and the connection part adopts a detachable structure 4. The detachable structure 4 consists of a pin shaft 41, a pin hole 42 and a plug rod 43. The bottom end of the pin shaft 41 is welded to the connecting seat 35, the pin shaft 41 is inserted into the signal lamp box 5, the pin hole 42 is arranged inside the signal lamp box 5, and the plug rod 43 passes through the pin shaft 41 through the pin hole 42. The signal lamp box 5 is connected to the connecting seat 35 by the detachable structure 4 through pin insertion. The cooperation between the plug rod 43 and the pin hole 42 on the pin shaft 41 ensures the stability and reliability of the signal lamp box 5 fixed on the connecting seat 35, and the detachable structure facilitates the replacement of the lamp box for maintenance or inspection, extending the service life of the railway signal lamp. See specifically Figure 3 , Figure 4 .
