Abstract

The utility model relates to an H-shaped monopolar type slide-contact wire which comprises a slide-wire conductor and a connecting plate, wherein a connecting terminal is arranged at the upper part of the slide-wire conductor, a groove is formed at the lower part of the connecting plate, and the connecting terminal is mounted inside the groove and is installed and fixed through a fastener. The H-shaped monopolar type slide-contact wire is characterized in that the cross sections of the connecting terminal at the upper part of the slide-wire conductor and the groove at the lower part of the connecting plate are both wedged, and the outer wall of the connecting terminal is in close contact with the inner wall of the groove. The H-shaped monopolar type slide-contact wire has a simple and reasonable structure. The cross sections of the connecting terminal and the groove are both wedged so as to ensure that the installation is more stable. After installation, the outer wall of the connecting terminal is in close contact with the inner wall of the groove without gaps, so that the slide-wire conductor is mounted inside the connecting plate with no problems of distortion and displacement, and the current collector carbon brush slides on the inverted V-shaped slide contact surface inside the slide-wire conductor more smoothly. Both the top part and the lateral part of the connecting terminal are in contact with the inner wall of the groove, thereby increasing the conducting area and minimizing the cost.

Description

H shape acyclic type trolley

Technical field

The utility model relates to a kind of trolley of slide-contact-type power transmitting device, specifically is a kind of H shape acyclic type trolley.

Background technology

Along with the quickening of economic development and process of industrialization, safety sliding contact line is as a kind of electric supply installation of mobile device, its range of application more and more widely, common its is used for the transmission of electricity power supply of occasion hoisting machineries such as workshop lifting, streamline production and port cargo.

In the prior art; connecting plate groove on the trolley is generally rectangular configuration; and the side angle that is installed in the slip conductor in the connecting plate groove also is rectangle; between the inwall of the outer wall of slip conductor and connecting plate groove certain interval is arranged; when the slip conductor is installed in the connecting plate; produce the distortion inconsistent phenomenon through regular meeting between the slip conductor of two butt joints, and then cause two inverted V-shaped wiping faces on the adjacent slip conductor also to produce dislocation.The current-collector carbon brush during slip power taking, sparking occurs easily in this inverted V-shaped wiping face, beat and fault such as loose contact, and what the equipment of influence used and produced normally carries out, when serious even burning apparatus; And this dislocation can aggravate the wearing and tearing of current-collector carbon brush, shortened the useful life of equipment.

In addition, effective conductive area between the connecting plate of this structure and the slip conductor is less, is easy to generate temperature rise in the junction, under the bigger situation of trolley electric current demand, reaching satisfactory contact conductive area just needs to strengthen the size of trolley, causes production cost to increase.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and reasonable, installs firmly, does not have the distortion inconsistent phenomenon, reduces the H shape acyclic type trolley of failure rate and cost savings greatly.

The purpose of this utility model realizes by following technical scheme: described H shape acyclic type trolley comprises slip conductor and connecting plate, slip conductor top is provided with link, the connecting plate bottom is provided with groove, link is assemblied in the groove, install and fix by securing member, it is characterized in that: the cross section of described slip conductor upper linker and connecting plate lower recess all is a wedge structure, the outer wall of link closely contacts with the inwall of groove, receives the inner groovy that forms wedge shape in the both sides outer wall of described slip conductor.

As further improvement of the utility model, described securing member comprises bolt, nut and clip plate, clip plate is pressed on the upper surface of this inner groovy, and the both sides of clip plate press closer the madial wall of inner groovy, and screw bolt and nut is with clip plate, slip conductor and connecting plate is fastening is installed together.

The utility model is simple and reasonable, compared with prior art, because the cross section of link and groove all is a wedge structure, installs more firm; The outer wall that the back link is installed closely contacts with the inwall of groove, and is very close to each other, and there is not the distortion inconsistent phenomenon in the slip conductor when being installed in the connecting plate, and the slip on the inverted V-shaped wiping face of current-collector carbon brush in the slip conductor is more smooth and easy; The top of link and sidepiece all contact with the groove inwall, and conductive area is bigger, and cost is saved more.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As Fig. 1, shown in Figure 2, described H shape acyclic type trolley comprises slip conductor 1 and connecting plate 4, slip conductor 1 top is provided with link 2, connecting plate 4 bottoms are provided with groove 3, link 2 is assemblied in the groove 3, install and fix by securing member, described securing member is by bolt 5, nut 6 and clip plate 10 constitute, receive the inner groovy 9 that forms wedge shape in the both sides outer wall of slip conductor 1, clip plate 10 is pressed on the upper surface of this inner groovy 9, the both sides of clip plate 10 press closer the madial wall of inner groovy 9, and bolt 5 and nut 6 are with clip plate 10, slip conductor 1 and connecting plate 4 fastening being installed together; The cross section of described slip conductor 1 upper linker 2 and connecting plate 4 lower recess 3 all is a wedge structure, and it is more firm to make that installation connects; When link 2 is assemblied in the groove 3; The outer wall of link 2 closely contacts with the inwall of groove 3, and is very close to each other, and there is not the distortion inconsistent phenomenon in slip conductor 1 when being installed in the connecting plate 4.

As shown in Figure 1 and Figure 2, floor 7 in the middle of the described slip conductor 1 is the inverted V-shaped structure, the lower surface center fixed of this inverted V-shaped floor 7 is equipped with the metal slide plate 7 of the inverted V-shaped that adopts the stainless steel material making, form inverted V-shaped wiping face 8, the current-collector carbon brush is assemblied in the slip conductor 1, the carbon brush surface contacts the slip power taking with inverted V-shaped wiping face.

Link 2 tops of slip conductor 1 and sidepiece all contact with groove 3 inwalls of connecting plate 4 in the utility model, and under the identical situation of conductive area, it is littler that the size of trolley can design; Under the condition of same size, the conductive area of trolley is bigger, can save cost effectively.
