Abstract

The utility model relates to a threading pipe, in particular to a threading pipe for a crane. The threading pipe is arranged in a single girder body, with both ends connected with holes on the single girder. From the technical scheme we can see that the threading pipe is arranged in the single girder body and can prevent a wire and the threading pipe from being damaged simultaneously when the crane lifts and transports; and simultaneously, the service life can be prolonged when the wire passes through the threading pipe.

Description

The hoisting crane penetration pipe

Technical field

The utility model relates to a kind of penetration pipe, relates to a kind of penetration pipe that is used for hoisting crane specifically.

Background technology

At present, mono beam crane in bridge type and trolley crane are agent structure with single girder, the end carriage at outfit two and mechanical drive and electric system are combined as complete equipment, and i shaped steel on single girder or T-steel form the track of moving cucurbit (the being commonly called as dolly) operation of power supply.The electrical motor of hoisting crane two end carriage links to each other by electric wire, and send signal by controller and make it along the end carriage orbital motion, at present, connect the outside that electric wire between two end carriages directly is fixed on girder mostly, it is the outside of web, there is certain potential safety hazard in this, in the manufacturing process of hoisting crane own, because the needs of lifting transhipment, the web one side elder generation land of electric wire arrangement often occur, so electric wire and penetration pipe are damaged together, and because electric wire is exposed for a long time outside, also can wear out too early, reduce service life, being located at the outside simultaneously also influences attractive in appearance.

Summary of the invention

The purpose of this utility model just provides a kind of safety and the long hoisting crane penetration pipe of period of service.

For achieving the above object, the utility model has adopted following technical scheme: penetration pipe is arranged on the inside of single-beam beam body, and its two ends link to each other with hole on being arranged on single-beam.

As shown from the above technical solution, the utility model selects penetration pipe is located at the inside of single-beam beam body, can avoid hoisting crane electric wire in the process of lifting transhipment to be damaged simultaneously with penetration pipe, and the while electric wire is located in the penetration pipe and also can prolongs its service life.

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the structural representation of another kind of implementation of the present utility model;

Fig. 4 is that the A-A of Fig. 2 is to view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Hoisting crane single-beam 20 as shown in Figure 1 and Figure 2, penetration pipe 10 is arranged on the inside of single-beam 20 beam bodies, and its two ends link to each other with hole on being arranged on single-beam 20.Penetration pipe 10 is arranged on the inside of single-beam 20 beam bodies along the span direction of single-beam 20, being penetration pipe 10 be arranged in parallel along web 21 inboards of single-beam 20, the two ends of penetration pipe 10 are respectively equipped with kink, its overbending direction points to any side of two coxostermums 21, and two holes on the web 21 of the kink of penetration pipe 10 and its side pointed link to each other.

As preferred version of the present utility model, selection is arranged on penetration pipe 10 inside of single-beam 20 beam bodies along the span direction of single-beam 20, it is the method to set up that connects shortest path between two end carriages, be provided with like this except making penetration pipe 10 usefulness materials few, the electric wire that connects between the two end carriage electrical motors relatively also is few, because be provided with along the span direction, promptly penetration pipe 10 is linearly arranged in the inside of single-beam 20 beam bodies, so also comparatively convenient when threading.Because the bottom of single-beam 20 is the track 24 of trolley travelling, both sides are and end carriage bonded assembly end plate 22, so can only be chosen in and offer the hole on the cover plate 23 on top and the web 21 and communicate with penetration pipe 10, as preferred version of the present utility model, selection is arranged on the hole on the web 20 of single-beam 10, and the two ends of penetration pipe 10 are respectively equipped with kink and link to each other with the hole, this is because if perforate on the cover plate 23 on top, not too convenient when more rewiring or keeping in repair, and have dust etc. after 23 perforates of top cover plate and fall, offer the hole and link to each other so preferred version is chosen in web 21 with the two ends of penetration pipe 10.

The position in two holes is respectively near two ends plate 22 on the web 21, and the line of centers between two holes parallels with the shaft core line of penetration pipe 10 and is positioned at same plane, described penetration pipe 10 employing rigidity tubing or PVC materials.

As Fig. 2, shown in Figure 4, because a coxostermum 21 outsides of single-beam 20 are connected with slip support 30, as preferred version of the present utility model, selection is arranged on the position of penetration pipe 10 inboard of parallel and close opposite side web 21, be that penetration pipe 10 splits respectively on the web of both sides with slip support 30, the two ends of penetration pipe 10 bend to opposite side web 21 directions respectively, penetration pipe 10 and slip support 30 are actually that line of centers with single-beam 20 span directions is oppositely arranged like this, can make so whole single-beam 20 keep certain steadily, here said steadily is comparatively speaking, and do not mean that the positioned opposite of only depending on both keeps the steady of whole single-beam 20, it also is feasible being arranged on side direction, as shown in Figure 3.Penetration pipe 10 also can adopt other feasible material except adopting rigidity tubing or PVC material.

The two ends of penetration pipe 10 respectively with web 21 on the hole be connected mutually, can adopt welding manner that penetration pipe 10 is communicated with the hole, also can adopt other mode to be connected, but because the span of single-beam 20 is increasing, reached 20 meters---60 meters, so the inboard at two webs 21 is provided with reinforced rib 211 along its length direction, is provided with transverse horizontal brace rod 212 between the both sides reinforced rib 211, reinforced rib 211 is band iron or angle bar.

As preferred version of the present utility model, as shown in Figure 4, length direction along two webs 21 is provided with three reinforced ribs 211, wherein upper and lower two are adopted band iron, the middle angle bar that adopts, this is because the middle stressed maximum of that root adopts the relative holding capacity of angle bar big, and upper and lower two employing band irons can economical with materials.

Be arranged on single-beam 20 in-to-in penetration pipes 10 and be provided with the support seat that is connected with web 21 along its length direction, help seat for being arranged on the transverse horizontal brace rod 212 between two webs 21, penetration pipe 10 adopts U type card 40 to fix with transverse horizontal brace rod 212.

As preferred version of the present utility model, directly select the support seat of transverse horizontal brace rod 212 for use as penetration pipe 10, saved material, also make simultaneously designs simplification, in order further to strengthen fixedly penetration pipe 10, with penetration pipe 10 and support seat, promptly penetration pipe 10 fixes with transverse horizontal brace rod 212 with U type card 40.

In sum, the utility model selects penetration pipe 10 is located at the inside of single-beam 20 beam bodies, can avoid hoisting crane electric wire in the process of lifting transhipment to be damaged simultaneously with penetration pipe 10, and the while electric wire is located in the penetration pipe 10 and also can prolongs its service life.
