Abstract

The invention discloses a combined ladder-type cable bridge, which comprises a crossarm and a ladder edge, wherein the lower part of the ladder edge is provided with a bending edge; pressing tongues which are formed by stamping are arranged on the ladder edge in pairs, and openings of each pair of pressing tongues are opposite, a distance between tips of each pair of opposite pressing tongues is greater than the width of the crossarm, clamping tongues which are matched with the pressing tongues and formed by stamping and bending two side edges of the crossarm outwards are respectively arranged on two end parts of the crossarm, the clamping tongues are inserted into the pressing tongues to realize fixed connection between the crossarm and the ladder edge, and the lower end of the crossarm is pressed on the bending edge at the lower part of the ladder edge. According to the combined ladder-type cable bridge, the fixed connection between the crossarm and the ladder edge is realized by inserting the clamping tongues on the crossarm onto the ladder edge, and the lower edge of the crossarm is pressed on the bending edge at the lower part of the ladder edge to form the bridge; thus the crossarm and the ladder edge do not need to be welded together in the manufacturing process, convenience is provided for bulk transportation, and the transportation cost is effectively reduced; and the welding process is saved, and the whole beauty is increased.

Description

The combined type ladder-type cable bridge
Technical field
The invention belongs to the cable testing bridge field, especially relate to a kind of combined type ladder-type cable bridge.
Background technique
Tradition ladder type crane span structure is welded by ladder limit, both sides and some cross-arms, the curved arc hook that reinforing function is arranged in top, terraced limit, and the bottom folding has bending edges, cross-arm two ends to lie prone respectively on the bending edges of bottom, terraced limit, then firm welding.Because the welding job amount is big, causes lead time long, simultaneously, because welding, after surface treatment, local being prone to produces pore or plating leakage point, finally causes stream yellow water phenomenon.When transportation, because of its profile takes up room greatly, but weight is lighter relatively, and traffic expense is improved relatively.
Summary of the invention
The object of the invention is to provide a kind of combined type ladder-type cable bridge of transporting and need not to weld be convenient to.
For realizing above-mentioned purpose, the technological scheme that the present invention adopts is: a kind of combined type ladder type crane span structure comprises that cross-arm and bottom have the terraced limit of bending edges; The paired opening pressure tongue in opposite directions that forms through punching press that is provided with on the said terraced limit; Distance between this paired in opposite directions pressure tongue the tip of the tongue is greater than the width of said cross-arm; Be respectively equipped with the block tongue that matches with described pressure tongue on two ends of described cross-arm with the pressing and bending formation outwardly of this cross-arm dual-side; This block tongue inserts in the described pressure tongue realizes being fixedly connected of cross-arm and terraced limit, and the lower end of cross-arm is pressed on the bottom bending edges on terraced limit.
This programme is through the paired pressure tongue that is provided with on terraced limit; Be provided with and the block tongue of pressing tongue to match in the end of cross-arm; Described block tongue inserted in the described pressure tongue realize being fixedly connected of cross-arm and terraced limit, the lower end of cross-arm is pressed on the bottom bending edges on terraced limit, is combined into crane span structure; Thereby make no longer need cross-arm and terraced side weld be connected together during fabrication, be convenient to transportation in bulk, effectively reduced cost of transportation; The terraced limit of height of the same race is interchangeable, highly versatile.In addition, owing to press tongue and the formation of block tongue pressing and bending,, avoided the distortion and the various resource consumption that cause because of welding, increased overall aesthetics so in the production of crane span structure, saved welding process.

Embodiment
Below in conjunction with accompanying drawing technological scheme of the present invention is done detailed explanation.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; Combined type ladder-type cable bridge of the present invention; Comprise the terraced limit 1 and cross-arm 2 that have the bottom bending edges, the paired opening pressure tongue 3 in opposite directions that is provided with on the terraced limit, this presses between the tip of the tongue of tongue 3 distance greater than the width of cross-arm 2 in pairs; Cross-arm is respectively equipped with the block tongue 4 that matches with described pressure tongue 3 on 2 two ends; Block tongue 4 inserts to press realizes being fixedly connected of cross-arm and terraced limit in the tongues 3, the lower end of cross-arm 2 is pressed on the bottom bending edges on terraced limit, formation combined type ladder-type cable bridge.
In actual use, the pressure tongue 3 on the terraced limit 1 can be employed in punching press formation on the terraced limit 1, and the block tongue 4 of cross-arm 2 ends can be employed in the end of cross-arm 2 with dual-side pressing and bending formation outwardly.During installation, two terraced limits 1 are put well face-to-face, the bending edges 4 that cross-arm 2 two ends are outwards dug inserts corresponding the pressure in the tongue 3 on the terraced limit successively, is pressed onto until cross-arm on the following bending edges on terraced limit, promptly arrives final fixed position.
Characteristics of the present invention are that terraced limit, cross-arm no longer weld combination, bulk delivery, and goods carries out terraced limit, the quick plug-in mounting of cross-arm again behind the scene.The distortion of having avoided welding to cause, the various resource consumptions when reaching welding have been practiced thrift cost.The terraced limit of height of the same race is interchangeable, highly versatile; Also can assemble terraced limit plug-in mounting cross-arm more earlier during on-the-spot the installation, can save a large amount of installation human and material resources, effectively reduce cost.Clamp mounting type, realize through mould, enhance productivity, improve constant product quality, standardized program improves.

Claims (1)

1. a combined type ladder type crane span structure comprises that cross-arm and bottom have the terraced limit of bending edges; It is characterized in that; The paired opening pressure tongue in opposite directions that forms through punching press that is provided with on the said terraced limit; Distance between this paired in opposite directions pressure tongue the tip of the tongue is greater than the width of said cross-arm; Be respectively equipped with on two ends of described cross-arm this cross-arm dual-side block tongue that matches with described pressure tongue of forming of pressing and bending outwardly, this block tongue inserts realizes being fixedly connected of cross-arm and terraced limit in the described pressure tongue, and the lower end of cross-arm is pressed on the bending edges of bottom, terraced limit.
