Description

Angle steel formula overhead traveling crane wiping line expansion joint forms device

Technical Field

The utility model relates to an angle steel formula wiping line erection equipment, concretely relates to angle steel formula wiping line expansion joint forming device.

Background

The trolley line is a power supply device commonly used in modern factories, is used for supplying power to moving equipment, and consists of a trolley line guide rail 11 and a current collector 10, wherein the trolley line guide rail 11 is a fixed part and is connected with a power supply, and the current collector 10 is a sliding part and can slide on/in the trolley line guide rail 11 and contact with a copper bar to take power (figure 1). Because environmental temperature changes and leads to the wiping line to take place expend with heat and contract with cold easily, consequently, in order to guarantee its normal operating, need set up the expansion joint in certain distance. At present, the lower and commonly used angle steel formula wiping line of cost adopts an expansion joint 4 (fig. 2) that round steel 1 and sleeve pipe 2 location formed, but this kind of expansion joint perk easily, distortion, can lead to the current collector to scrape in wiping line course of operation and turn over, wiping line scrapes trouble such as bad, influences the safety and stability operation of overhead traveling crane, also can increase the maintenance cost of wiping line simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the above-mentioned defect that current angle steel formula wiping line expansion joint forming device exists, provide an angle steel formula wiping line expansion joint forming device that the structure sets up rationally, can guarantee to remove electrical apparatus safety and stability operation.

The utility model aims at realizing through the following technical scheme: an angle steel type sliding contact line expansion joint forming device comprises angle steel which is the same as an angle steel type sliding contact line structure, wherein two sides of a first end face of the angle steel are fixedly connected with the angle steel type sliding contact line, a step-shaped expansion joint extending to a second end face of the angle steel is arranged in the width direction of the first end face of the angle steel, and the angle steel is divided into two independent parts by the expansion joint; the inner sides of the first end surface and the second end surface of the angle steel are respectively provided with a guide rail, the guide rails are respectively provided with a guide plate covering the head and the tail of the expansion joint, and the joint of the head of the expansion joint and the angle steel is a slope.

As a further improvement of the technical scheme, above-mentioned angle steel second terminal surface both ends are equipped with the copper harness that can prevent electrically conductive damage between slide and the slide.

Compare with current angle steel formula wiping line expansion joint forming device, the beneficial effects of the utility model are that:

the utility model can prevent the deformation and dislocation of the expansion joint by arranging the sliding plate and the slide way on the two end surfaces of the angle steel; the expansion joint at the first end face of the angle steel is in a step shape to form a cross design, so that the expansion joint can be prevented from tilting due to a transverse gap; the contact part of the current collector and the expansion joint is processed into a slope shape, so that acute-angle scraping and rubbing of the current collector can be prevented; through set up the copper pencil at angle steel second terminal surface length direction both ends, can prevent the electrically conductive damage between slide and the slide. Through the combined arrangement, the current collector can smoothly pass through the expansion joint, stable power supply is guaranteed, meanwhile, the accident that the current collector is cut over is avoided, production is stabilized, and the maintenance cost of the sliding contact line and the current collector is saved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings:

as shown in fig. 3-4, an angle steel type trolley line expansion joint forming device includes an angle steel 3 having the same structure as an angle steel type trolley line 8, both sides of a first end surface of the angle steel 3 in a length direction are welded to the angle steel type trolley line 8, an expansion joint 4 having a step shape and extending to a second end surface of the angle steel 3 is provided in the width direction on the first end surface of the angle steel 3, and the angle steel 3 is divided into two independent parts by the expansion joint 4; the inner sides of the first end surface and the second end surface of the angle steel 3 are respectively provided with a guide rail 5, and the guide rails 5 are respectively provided with a guide plate 6 covering the head part and the tail part of the expansion joint 4. The joint of the head of the expansion joint 4 and the angle steel 3 is a slope 9, and two ends of the second end surface of the angle steel 3 in the length direction are provided with copper wire harnesses 7.

The device is welded between the two angle steel type sliding contact lines 8, when the temperature of the working environment changes, the angle steel type sliding contact lines 8 expand with heat and contract with cold, the expansion joint 4 is widened or narrowed through the relative movement of the guide plate 6 on the guide rail 5, so that the current collector 10 can smoothly pass through the expansion joint 4, the requirement of stable power supply of the angle steel type sliding contact lines 8 is met, and the maintenance cost of the angle steel type sliding contact lines 8 and the current collector 10 is saved.
