Abstract
The utility model provides a novel automatic forward/reversal collector bow frame device of a mining direct circuit (DC) electric locomotive, which belongs to the field of equipment for connecting mine wiring electric locomotive cables and the electric locomotive. The novel automatic forward/reversal collector bow frame device comprises a connecting plate and a collector bow strip, and is characterized in that the connecting plate is connected with the collector bow strip by a large limit swinging device and a small limit swinging device; the large limit swinging device is fixedly arranged on the connecting plate and is connected with the small limit swinging device; the small limit swinging device fixes a connection rotating shaft by insulation wood; and the two ends of the connection rotating shaft are fixedly provided with the collector bow strip. When the collector bow strip is contacted with an overhead line by virtue of the connection rotating shaft, rolling friction is generated between the collector bow strip and the overhead line so as to reduce the original friction, and thus the service life of the collector bow strip and the overhead line is prolonged. The automatic forward/reversal collector bow frame device provided by the utility model can ensure the safe running and reliable working of the electric locomotive, and has the advantages that the structure is simple, the service life of the overhead line and a bow is prolonged, the production cost is reduced, and the device is capable of rotating forward or reversely automatically, easy to implement and convenient to use and maintain, and the like.

Background technology
Along with science and technology constantly develops; Stringing direct-current electric locomotive current collection bow bar cliding friction increases the contact pressure of bow and air wire greatly; Shortened, life-span of air wire and bow, increase productive costs, direct-current electric locomotive is being turned or need manually controlled the current collection bow with the run rider when reverse simultaneously; Manually control to very difficulty of correct position, this brings very big difficulty, has very big potential safety hazard to the run rider.Therefore be badly in need of the technical personnel innovation transformation; Design a kind of safety, simple in structure, reliable operation, prolongation air wire and bow life-span, reduce production costs, can change current collection bow rack device automatically anyway by new type mining direct-current electric locomotive positive and negative automatically, that be easy to advantages such as realizing, working service is convenient.
The utility model content
According to above deficiency of the prior art, the problem that the utility model will solve is: provide a kind of can guarantee electric locomotive safe operation, reliable operation, simple in structure, prolong air wire and bow life-span, reduce production costs, can be positive and negative automatically, be easy to realize, working service easily the new type mining direct-current electric locomotive change current collection bow rack device automatically anyway.
The utility model solves the technical scheme that its technical matters adopted: the new type mining direct-current electric locomotive changes current collection bow rack device automatically anyway; Comprise connecting panel and current collection bow bar; It is characterized in that: connecting panel is connected current collection bow bar through big spacing pendulous device with little spacing pendulous device; Fixedly install big spacing pendulous device on the connecting panel; Big spacing pendulous device is provided with and connects little spacing pendulous device, and little spacing pendulous device connects the turning cylinder two ends and fixedly installs current collection bow bar through the wood that the insulate turning cylinder that is fixedly connected.
Produce friction of rolling when current collection bow bar contacts with air wire, little spacing pendulous device can freely swing at big spacing pendulous device, and big spacing pendulous device can freely swing on connecting panel.
Wherein preferred version is:
Described big spacing pendulous device comprises big swinging mounting, support turning cylinder, big support spring, first barrier rib, second barrier rib and block; Supporting turning cylinder is fixed on the connecting panel through bearing seat and bolt of rear end plate; Support the fixing big swinging mounting of turning cylinder; Between the big swinging mounting first barrier rib and second barrier rib are set, big support spring is arranged on and supports on the turning cylinder, and the two ends of big support spring are separately positioned on the block and first barrier rib.
Described little spacing pendulous device comprises little swinging mounting, turning cylinder, little support spring and the 3rd barrier rib; Turning cylinder is fixed on big swinging mounting; Turning cylinder is provided with rotary little swinging mounting; The 3rd barrier rib is set between the little swinging mounting, and little support spring is arranged on the turning cylinder, and the two ends of little support spring are separately positioned on second barrier rib and the 3rd barrier rib.
The new type mining direct-current electric locomotive of the utility model changes the beneficial effect that current collection bow rack device had automatically anyway: generation friction of rolling when current collection bow bar contacts with air wire by connecting turning cylinder; Changed original cliding friction; Reduced current collection bow bar and air wire friction, make current collection bow bar and air wire friction force, prolonged service life.
The utility model can guarantee electric locomotive safe operation, reliable operation, simple in structure, prolong air wire and bow life-span, reduce production costs, can be positive and negative automatically, be easy to realize, advantages such as working service is convenient.
Description of drawings
