Bridge inspection car running track manual shifter

Abstract

The invention provides a bridge inspection car running track manual shifter, and belongs to the field of bridge equipment. The bridge inspection car running track manual shifter comprises a rotary support, a rotary track, an upper rotating and positioning mechanism, a lower rotary supporting block and fixed connection supports; the rotary support is composed of a combination coupling shaft and a bearing pedestal, wherein the rotary support is installed in the bearing pedestal in a matched mode through a bearing outer ring and the lower end of the combination coupling shaft is connected with the rotary track. Two running tracks are located in the same horizontal plane, wherein an included angle is formed between the two running tracks, and the middle portions of the two running tracks are broken and respectively provided with two opposite internal end sockets; the four fixed connection supports are installed at corresponding joints of the internal end sockets of the two running tracks and the two end portions of the rotary track respectively. The combination coupling shaft is pushed manually to drive the rotary track connected to the lower end of the combination coupling shaft to rotate 360 degrees; when the rotary track rotates to a position where the two ends of the rotary track are in butt joint with the internal end sockets of the corresponding running tracks at the fixed connection supports respectively, the rotating and positioning mechanism is used for positioning and locking the rotary track, therefore, track transfer is realized, and the requirement that an inspection car changes running directions to conduct inspection and maintenance operation is met.

Description

technical field [0001] The invention relates to a manual track changing device for a bridge inspection vehicle, which belongs to the field of bridge equipment, and in particular relates to bridge inspection vehicle equipment. Background technique [0002] At present, there are mainly the following two ways of changing the track of the existing bridge inspection vehicle when it is running: first, the track changing of the slewing bearing, that is, the driving device drives the lower slewing support to move relative to the upper slewing support, so as to realize the The 360° rotation of the rotary track connected to the lower support of the slewing system is complex in structure and high in manufacturing cost. If the bridge needs multiple cross-bridge inspections, a large number of installations are required, resulting in high engineering costs and poor mass production economy. It is suitable for large-scale production; second, the height difference track change track, this tr...

[0002] At present, there are mainly the following two ways of changing the track of the existing bridge inspection vehicle when it is running: first, the track changing of the slewing bearing, that is, the driving device drives the lower slewing support to move relative to the upper slewing support, so as to realize the The 360° rotation of the rotary track connected to the lower support of the slewing system is complex in structure and high in manufacturing cost. If the bridge needs multiple cross-bridge inspections, a large number of installations are required, resulting in high engineering costs and poor mass production economy. It is suitable for large-scale production; second, the height difference track change track, this track change device is formed by laying two tracks with a certain height difference, the two tracks go up and down, and cross each other, when the track change operation , it is necessary to disassemble the track at the intersection of the running track first, and then install the track at the intersection on another track that needs to be changed. This way of changing the track requires dismantling the current track and installing the upcoming track every time the track is changed. long time for disassembly and installation will affect the maintenance progress, and high-altitude operations are very dangerous, the workload is large, the maintenance period is long, the operation is complicated, and the operability is not strong
