Abstract
The present utility model relates to a slipper current collector for powering up mobile equipment and specifically provides a constant-force current collector, which comprises a connection support, a cutter head support and a contact cutter head. The slipper current collector is characterized in that the cutter head support is connected with the connection support through an elastic connector used for elastically supporting the cutter head support. According to the technical scheme of the utility model, the support spring of the connection support of an original current collector is adopted as a primary adjustment mechanism, and the elastic connector is adopted as a secondary adjustment mechanism. The elastic force between the cutter head and a slip wire is ensured to be sufficient by means of the elastic connector. In this way, even used on a road segment of a slightly non-uniform levelness, the contact pressure of the constant-force current collector is ensured to be sufficient. Meanwhile, the deformation of the slip wire under the effect of an overlarge elastic force can be avoided. Therefore, the phase-loss faults of electrical equipment can be eliminated.
Description
Technical field
The utility model relates to mobile power supply equipment slide wire collector, specifically a kind of constant force current-collector.
Background technology
In industrial and mining enterprises, mobile power supply equipment often can reach hundreds of rice by the slip length of slide wire collector, owing to can not ensure abswolute level in the initial process of installing of equipment, through nearly operation for a long time, slip there will be obvious height to rise and fall or local deformation again, and average level degree declines.
What general mobile device adopted is Integral three-phase slide wire collector and single-phase type slide wire collector, four single-phase type slide wire collectors of employing that power is larger.Referring to Fig. 1, the contact cutter head of current-collector is by cutter head stent support, cutter head support is fixed on by the support bar of its underpart on the structure stand of link, contact between contact cutter head and slip only relies on the spring of link to regulate, current-collector is in operation and just has the chance that does not reach slip, thereby causes mining equipment electric power phase shortage, and equipment can not run well, incur loss through delay project progress, also can motor damage.Therefore, overcome the above problems imperative.
Utility model content
The technical problems to be solved in the utility model is, a kind of constant force current-collector is provided, can ensure that the contact of current-collector on slip can not depart from slip, thereby guarantee no matter slip slides to any position, and contact force is constant, even if slip has fluctuating, current-collector also can reliably contact, the normal operation of guarantee equipment, minimizing equipment, because of electric power phase shortage initiating failure, is enhanced productivity.
For solving the problems of the technologies described above, the utility model adopts following technical proposals:
A kind of constant force current-collector, comprises link, cutter head support, contact cutter head, and described cutter head support is connected with described link by the Flexible Connector that it is carried out to resiliency supported.
The utility model that adopts technique scheme, compared with prior art, its beneficial effect is:
By the stand spring of the link of former current-collector as main regulation, utilize Flexible Connector to regulate as pair, Flexible Connector can make to keep between cutter head and slip enough elastic force, even be not that section also can keep enough contacts especially uniformly in levelness, can not make because elastic force is excessive again trolley distortion simultaneously, make that electric equipment is unlikely to break down because of phase shortage.
As preferably, the utility model further technical scheme is:
Its main body of described Flexible Connector is a short metal pipe, described short metal pipe is fixed on described link by connection handle, the support bar of described cutter head support bottom inserts in described short metal pipe, in described short metal pipe, spring is housed, and described spring top resiliency supported is in described support bar.Adopt such Flexible Connector, make the utility model structure simpler, be easy to make, and be convenient to assembling.
The described short metal pipe bottom end cap that has been threaded, the lower end of the spring in described short metal pipe and described end cap are fixed, and described end cap is provided with regulating handle.By the position that rotation regulating handle can facilitate, labour-saving regulates end cap, and then the position of regulating spring, make spring there is best support effect to support bar.
On the tube wall of described short metal pipe, symmetry has slotted hole, and described support bar lower end is fixed with the pin spacing by described slotted hole.Such structure, while making support bar flexible in short metal pipe, because pin can block at slotted hole two ends, unlikely coming off run out of short metal pipe.
Brief description of the drawings
Fig. 1 is existing common current collector structural representation;
Fig. 2 is the structural representation of the utility model embodiment;
Brief description of the drawings: 1-link, 2-contacts cutter head, 3-cutter head support, 4-support bar, 5-short metal pipe, 6-pin; 7-slotted hole, 8-spring, 9-end cap, 10-regulating handle, 11-connection handle.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, and object is only to understand better the utility model content.
Referring to Fig. 2, the constant force current-collector that the present embodiment provides, by link 1, contact cutter head 2, cutter head support 3 and Flexible Connector composition, link 1, contact cutter head 2, link in cutter head support 3 and existing current-collector, contact cutter head, cutter head supporting structure is identical, its main body of Flexible Connector is that a segment length is 90mm, the short metal pipe 5(of diameter 20mm is intercepted by coating steel pipe), short metal pipe 5 is fixed on the structure stand of link 1 by two connection handles 10, the short metal pipe 5 bottoms end cap 9 that has been threaded, end cap 9 is provided with regulating handle 10, spring 8 is housed in short metal pipe 5, the lower end of spring 8 and end cap 9 are fixing, the support bar 4 of cutter head support 3 bottoms inserts in short metal pipe 5, and the spring 8 top resiliency supported of short metal pipe 5 are in support bar 4, on the tube wall of short metal pipe 5, symmetry has a pair of slotted hole 7, and support bar 4 lower ends are fixed with pin 6, and pin 6 can be spacing by the upper and lower end of slotted hole 7 in the time that support bar 4 is flexible.
Above-mentioned constant force current-collector is dialled on coal machine and is used at impeller, the failure rate causing because of current-collector loose contact, power phase shortage greatly reduces, fundamentally solve the problem of power phase shortage, reduce the maintenance of slip and current-collector, save manpower, improved efficiency, laid a good foundation for the safe and stable operation of equipment, comprehensive benefit is remarkable.
