Abstract

The utility model discloses a current collector slide block in a square shape, and four side surfaces are completely identical. Therefore, the mounting direction of the current collector slide block can be changed to prolong the service life of the current collector slide block.

Description

A kind of collector-block

Technical field

The utility model relates to a kind of collector-block, more particularly, relates to a kind of collector-block increasing the service life.

Background technology

Power-supply trolley line apparatus is that movement, slewing (comprising crane, purlin car, crane etc.) provide electric energy, and assurance equipment continues mobile operating.Power-supply trolley line apparatus is comprised of two parts, slide-wire guide rails and current-collector.Slide-wire guide rails is standing part, joins with power supply, and slide-wire guide rails is formed by connecting by the guide rail of singly growing 4 meters/root or 6 meters/root, current-collector is slipper, for being connected with mobile motor, can on slide-wire guide rails or in slide-wire guide rails, slide, and with conductor contact power taking.

As everyone knows, collector-block is one of most important part in current-collector, by collector-block, can realize the sliding contact between current-collector and slip, then by power delivery to equipment.

Figure 1A and Figure 1B are front view and the end view of collector-block of the prior art, and Fig. 1 C is that collector-block of the prior art is installed to the sectional view after slide block fixture.

With reference to Figure 1A, Figure 1B and Fig. 1 C, the lower end of slide block 10 is fixedly mounted in slide block fixture 20, and the upper surface of slide block 10 contacts with slide-wire guide rails.As shown in Figure 1B and 1C, the lower end of slide block 10 is right angle, and the way of contact being therefore fixedly connected with slide block fixture 20 is right angle contact.

Because the sliding friction between slide block and slip causes the wearing and tearing of slide block, and then affect providing of power-supply trolley line apparatus electric energy, especially, in the situation that work condition environment (bisque, granular substance) is severe, slider wear situation is more serious, and the life-span sharply reduces.Therefore, the useful life of collector-block of the prior art is shorter.

Utility model content

The purpose of this utility model is to solve in prior art that sliding friction between slide block and slip causes slider wear and problem that slide block is reduced useful life.

To in ensuing description, part set forth aspect the utility model general plotting and/or advantage, some will be clearly by description, or can be by the enforcement of the utility model general plotting is learnt.

According to one side of the present utility model, a kind of collector-block is provided, it is characterized in that, described collector-block is square, four side surfaces are identical.

One end that described collector-block is installed to slide block fixture is processed to swallow-tail form, to be installed in the dovetail groove of slide block fixture.

Four side chamferings that described collector-block contacts with slide-wire guide rails.

Because collector-block of the present utility model is square slide block, therefore can reach and extend the slide block object in useful life by conversion slide block installation direction.On the other hand, even if still can guarantee the contact-making surface of slide block and slide-wire guide rails after wearing and tearing, guarantee amount of power supply.Described slide block can be widely used in mobile electrical appliance power supply device.

Accompanying drawing explanation

By the description of embodiment being carried out below in conjunction with accompanying drawing, these and/or other aspect advantage of the present utility model will become clear and be easier to and understand, wherein:

Figure 1A is the front view of collector-block of the prior art;

Figure 1B is the end view of collector-block of the prior art;

Fig. 1 C is that collector-block of the prior art is installed to the sectional view after slide block fixture;

Fig. 2 A is the front view according to collector-block of the present utility model;

Fig. 2 B is the end view according to collector-block of the present utility model;

Fig. 2 C is according to the sectional view after collector-block of the present utility model and the fixed installation of slide block fixture;

Fig. 3 is the schematic diagram contacting with slip before wearing and tearing according to collector-block of the present utility model;

Fig. 4 contacts schematic diagram with slip according to collector-block of the present utility model after wearing and tearing;

Fig. 5 is according to the sectional view after collector-block wearing and tearing of the present utility model.

Wherein, 10 is collector-block of the prior art, and 20 is slide block fixture of the prior art, and 100 is collector-block of the present utility model, and 200 is slide block fixture of the present utility model, and 300 is slip.

Embodiment

Now embodiment of the present utility model is described in detail, in the accompanying drawings, wherein, identical label represents same parts to its example shown all the time.Below with reference to the accompanying drawings embodiment is described to explain the utility model.

Collector-block of the present utility model and collector-block difference of the prior art are that described collector-block is square but not rectangle on the whole.In other words, the length direction of collector-block and Width measure-alike, and the shape full symmetric of four sides.

Fig. 2 A and Fig. 2 B are respectively according to the front view of collector-block of the present utility model and end view, and Fig. 2 C is for to be installed to the sectional view after slide block fixture according to collector-block of the present utility model.

Collector-block of the present utility model can process by four-prism.As shown in Fig. 2 A, Fig. 2 B and Fig. 2 C, the front view of collector-block 100 of the present utility model is identical with right view shape.The face of the upper surface of collector-block 100 for contacting with slide-wire guide rails, lower end is fixedly mounted in slide block fixture 200.In the upper end with slide-wire guide rails joint, rounding is carried out at four side angles that slide block is contacted with slide-wire guide rails, thereby smoothly contacts with slide-wire guide rails 300 when collector-block 100 is slided on slide-wire guide rails 300.In order to prevent that collector-block 100 from coming off from slide block fixture 300, in slide block fixture 200, process dovetail groove, and the bottom of slide block 100 is processed to corresponding swallow-tail form, thus slide block 100 is stably stuck in slide block fixture 200, and be not easy to come off.

Fig. 3 is the schematic diagram contacting with slip according to before collector-block wearing and tearing of the present utility model, and Fig. 4 is the schematic diagram contacting with slip according to after collector-block wearing and tearing of the present utility model, and Fig. 5 is according to sectional view after collector-block wearing and tearing of the present utility model.For ease of setting forth, the square contact-making surface that slide block 100 is contacted with slip 300 is divided into a, b, tri-regions of c, and the region contacting with slip 300 in the middle of slide block is c district, and the left and right sides in c district is respectively a district and b district.C district and slip 300 sliding friction effects, produce wearing and tearing, when c district may wear to can not meet instructions for use time, by slide block 100 half-twists.Due to the wearing and tearing generation groove of slide block c district and slip 300, therefore, after half-twist, slide block and slip contact area become a, b district.A, b district and slip sliding friction, and then extended useful life of slide block.

By finding out description of the present utility model above, collector-block of the present utility model has reached the object in prolongation slide block useful life by the installation direction of conversion slide block.On the other hand, also increase the contact-making surface of slide block, guaranteed amount of power supply.

Although represented and described embodiment more of the present utility model, but, it should be appreciated by those skilled in the art, in the situation that not departing from principle of the present utility model and spirit, can make in these embodiments change, scope of the present utility model is limited by claim and equivalent thereof.
