Problems solved by technology

[0002] At present, none of the track flat trolleys used in track construction have the function of automatic braking and parking. In the environment of ramp construction, it is very easy to slip and cause safety accidents. It is not realistic to rely solely on rules and regulations to restrict workers to work safely. How to rely on equipment The design of technical functions enables the rail trolley to achieve the goals of simple structure, convenient use, automatic parking, safety and reliability, which has become an urgent need for current on-site construction

Embodiment Construction

[0012] Such as figure 1 As shown, under the normal state of parking, the brake pads 16 attached to the brake pad bracket 6 tightly embrace the track roller 2 under the action of the tension spring 5, so that the whole vehicle is in a static state; when normal operation is required, the staff The hand push rod 13 must be rotated 90° clockwise to make it in an upright position, and the brake torsion shaft 8 is driven to rotate 90°. The brake pad positioning piece 9 fixed together with the torsion shaft 8 also rotates 90° thereupon, and the left and right soft steel wires 14, 14' connected with it are pulled to drive the brake pad bracket 6 to rotate around the pin shaft hinge 3, so that the brake pad 16 is detached from the track roller 2 wheels.

Abstract

The invention provides an automatic parking braking type railway track trolley and belongs to the field of track construction equipment. The automatic parking braking type railway track trolley is characterized in that braking devices are installed on the inner sides of front track idler wheels on the lower face of a trolley frame; each braking device is of a structure that a brake rubber block support of a brake rubber block is installed on the position attached to the wheel face of the corresponding front track idler wheel; the middle portion of each brake rubber block support is hinged and fixed to the trolley frame through a pin shaft, the upper end of each brake rubber block support is connected with the trolley frame through a tension spring, and the lower end of each brake rubber block support is connected with a soft steel wire; each soft steel wire is wound around a channel-shaped guide wheel to be connected with a brake locating sheet fixed to a braking torsion shaft; and the front end and the rear end of the braking torsion shaft are hinged to fixing boards on the trolley frame, one end of a torsion spring arranged on a braking handle shaft in a sleeving manner is connected with the trolley frame, the other end of the torsion spring is connected with the braking handle shaft, and the front end and the rear end of the braking torsion shaft are hinged to a hand push rod through pin shafts. The automatic parking braking type railway track trolley has the beneficial effects of being capable of achieving automatic parking braking, simple in structure, safe and reliable.

Description

technical field [0001] The invention belongs to the field of track construction equipment, and in particular relates to an automatic braking type railway track trolley. Background technique [0002] At present, none of the track flat trolleys used in track construction has the function of automatic braking and parking. In the environment of ramp construction, it is very easy to slip and cause safety accidents. It is not realistic to rely solely on rules and regulations to restrict workers to work safely. How to rely on equipment The design of technical functions enables the rail trolley to achieve the goals of simple structure, convenient use, automatic parking, safety and reliability, which has become an urgent demand for current on-site construction. Contents of the invention [0003] The object of the present invention is to provide an automatic parking brake type railway track trolley, which can effectively overcome the shortcomings of the prior art. [0004] The pres...
