Abstract
A turnover plate type electric push rod locking device is characterized by consisting of a bottom mounting plate, an electric push rod, a trunnion mounting seat, a turnover plate, a turnover plate supporting seat, a locking wheel, a stroke switch and a stroke switch mounting frame. The upper part of the electric push rod is arranged on the turnover plate by a trunnion; the lower part of the electric push rod is connected on the turnover plate by a hinge shaft; the locking wheel is assembled on the turnover plate by a sliding bearing and then is arranged on the supporting frame by the supporters at the two ends of the sliding bearing; the stroke switch is arranged on the stroke switch mounting frame according to a designed rotating design; a trunnion seat, the turnover plate supporting seat and the stroke switch mounting frame are assembled on the bottom mounting plate by bolts to form a locking device assembly. The locking device is adopted by a straddle type single-rail traffic; the electric push rod drives a rotating handle with an idler wheel to be locked in a compulsory pressing-in type, thus realizing the reasonable layout of the structure of the whole machine simultaneously when perfectly ensuring the safety of the locking device.
Description
Technical field
The utility model belongs to the orbital facilities technical field, particularly the track switch accessory device.
Background technology
The straddle-type Rail Transit System is a kind of novel traffic mode that grows up gradually in China in recent years, for filling up and promoting China's energy field of traffic to have long-range economic benefit and social benefit.Blocking device is as the track switch parts of most critical wherein, and the reliability of motion control, accuracy are particularly important to the safety in operation of track switch.The lockout mechanism of city rail traffic was feed screw nut straight line or electric pushrod straight line blocking device in the past.
Summary of the invention
The utility model purpose relates to a kind of track switch vibrator of rotating disc type electric pushrod blocking device, ensures safety, accuracy, the real-time of blocking device as far as possible.
Specifically, a kind of vibrator of rotating disc type electric pushrod blocking device is characterized in that by base plate (1), electric pushrod (11), gudgeon mount pad (12), returning face plate (4), returning face plate supporting seat (8), locking wheel (5), travel switch (10), travel switch erecting frame (9) formation are installed; Electric pushrod top adopts gudgeon to be installed on the returning face plate, and the bottom is connected on the returning face plate by hinge; Locking wheel uses plain bearing to be assembled on the returning face plate, is installed on the supporting seat by the plain bearing two end supports again; Travel switch is installed on the travel switch erecting frame according to the design rotational travel, and trunnion seat, upset supporting seat, travel switch erecting frame are assembled in to install on the base plate by bolt forms locking device assembly.
Cross-saddle single-track traffic adopts the utility model, and the turning handle of electric pushrod rotating band roller is forced forced locking, has perfectly solved when ensureing the blocking device safety realization of said device features rational structure layout.Its advantage specifically has: 1. satisfy under the track switch blocking track switch fully and cross intensity, the rigidity property of car for various load; 2. this device is an electromechanical controlling device, and use is efficient, safeguards simple and easyly, has the actv. overload protection device, can prevent the destruction of mechanical device; 3. having improved parts such as complete machine and blocking device is easy to install, debugs and maintenance; 4. be that power lead and control signal wire adopt distribution form under the beam, make the track switch compact integral structure leave enough design and installation spaces; 5. lock and the two states of unblanking is respectively arranged with two position switchs, detect and have higher reliability.
The utility model promotes and perfect cross-saddle single-track traffic turnout technology, for the exploitation of city rail traffic field and engineering transportation rack device Related product provides technical support and reference.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 lateral plan.
Figure number explanation: 1-installs base plate, 2-inhibiting device, 3-plain bearing, 4-returning face plate, 5-locking wheel, 6-chassis, 7-supporting seat, 8-upset supporting seat, 9-travel switch mount pad, 10-travel switch, 11-electric pushrod, 12-gudgeon mount pad.
The specific embodiment
As shown in Figure 1 and Figure 2, blocking device is under the prerequisite that the complete machine structure layout allows, for safety, accuracy, the real-time that ensures blocking device as far as possible, lock slots is arranged on the sole plate, securing rod drives locking wheel and adopts the convertible lock slots that is pressed into to lock, require accurate positioning and lock firmly, can overcome vehicle by the time centnifugal force and the impulsive force that produce.According to track switch complete machine turn-out track operation sequential, must realize locking and unblanking in specific time, must be provided with position probing and control to realize that complete machine is coordinated to detect with travel switch, blocking device adopts direct motor drive in addition, when can't direct motor drive, can adopt manual mode to drive.The manual drives function must be set, to realize manual drives locking and unlocking action.
Blocking device is after the track switch beam is driven in place, and the device that makes its accurate contraposition and firmly lock is installed in respectively on the chassis side.Blocking device is made of parts such as base plate, electric pushrod, gudgeon mount pad, returning face plate, returning face plate supporting seat, locking wheel, travel switch, travel switch erecting frame are installed.The gudgeon mounting means is adopted on electric pushrod top, and the bottom is connected on the returning face plate by hinge; Locking wheel uses plain bearing to be assembled on the returning face plate, is installed on the supporting seat by the plain bearing two end supports again; Travel switch is installed on the travel switch erecting frame according to the design rotational travel, trunnion seat, upset supporting seat, travel switch erecting frame are assembled in to install on the base plate by bolt forms locking device assembly, plain bearing all adopts high-tensile strength brass high-abrasive material, has highly efficient durable, is easy to install and change.Blocking device promotes returning face plate around axial rotation by electric pushrod, and returning face plate will lock roller and be pressed in the lock slots by force under the effect of electric pushrod, the back inhibiting device that puts in place is issued to bit instruction, electric pushrod quits work, and realizes the locking of track switch, can realize the release of track switch on the contrary.Adopted the turning handle of electric pushrod rotating band roller to force forced locking, be to push away under the rotation of electric pushrod drive locking wheel, position to travel switch control, send and lock the signal that puts in place, send signal: all position switchs carried out comprehensively relatively sending the signal that puts in place to control center after track switch put in place.According to the analysis of track switch load structural stress, structural distortion and the power of returning face plate, turnover bracket, locking roller, lock slots, electric pushrod is carried out strict inspection and calculate, thereby satisfy intensity, the rigidity of blocking device, the designing requirement of safe reliability.
