Description
Technical field
The invention belongs to track construction apparatus fields, and in particular to a kind of automatic railroad track trolley of formula in brake.
Background technology
Currently, the track flat bogie used in track construction is constructed all without automatic brake parking function in ramp
Under environment, easily safety accident occurs for car slipping, rules and regulations constraint safety of workers operation and unrealistic is depended merely on, how by equipment
The design of technical functionality so that track wooden handcart reaches simple in structure, easy to use, automatic parking, safe and reliable target, becomes
The active demand of current live construction.
Invention content
It is an object of the present invention to provide a kind of automatic railroad track trolleies of formula in brake, can effectively overcome of the existing technology lack
Point.
The invention is realized in this way as shown in Figure 1, including vehicle frame 1 and the front and back track roller below vehicle frame 1
2,2 ', it is characterized in that 2 inside of track roller is equipped with brake gear before below vehicle frame 1, the structure of the brake gear is such as figure
1, shown in 2,3, the brake rubber block holder 6 equipped with brake rubber block 16, brake rubber block holder are installed at the wheel face close to preceding track roller 2
6 central raised positions are fixed on by axis pin hinged 3 on vehicle frame 1, and the upper top end of brake rubber block holder 6 passes through tension spring 5 and guide wheel
Fixed frame 15 connects, and guide wheel fixed frame 15 is fixedly mounted on vehicle frame 1；The lower end of brake rubber block holder 6 is connect with stone dead wire 14, soft
Steel wire 14 connect around flute profile guide wheel 4 with the brake locating plate 9 being fixed on brake torsional axis 8, and flute profile guide wheel 4 is mounted on guide wheel
On fixed frame 15, guide wheel fixed frame 15 is fixed on vehicle frame 1；The rear and front end of brake torsional axis 8 is supported on front and back stop bit respectively
Baffle 10,10 ' is upper to be hinged with front and back lock plate 10,10 ', and front and rear baffle 10,10 ' is respectively fixedly connected on vehicle frame 1；It turns round
Spring 17 is sleeved on brake torsional axis 8, and one end of torsional spring 17 is fixedly connected with vehicle frame 1, and the other end is fixed with brake torsional axis 8 to be connected
It is connected together；The rear and front end of brake torsional axis 8 is hinged by front and back axis pin 12,12 ' with handspike 13 respectively.
Advantages of the present invention and good effect are：1. handspike, brake torsion bar are combined into one, un-brake is light, resets brake
Reliably；2. self-actuating brake when unattended is in safe park mode；3. portable construction, loading capacity are big, on the track on abrupt slope
It can realize and be fully loaded with safe parking；4. handspike is detachable, it is front and back can safety operation.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is brake gear schematic diagram；
Fig. 3 is K direction views in Fig. 2；
