Description

Novel simply assemble over-and-under type portal frame

Technical Field

The utility model relates to a direct-burried insulating tube simply assembles over-and-under type portal frame construction field, concretely relates to novel simply assemble over-and-under type portal frame.

Background

The direct-buried heat-insulating pipeline of the centralized heat supply networking capacity expansion and network expansion engineering is constructed in the groove, and a portal frame is required to hoist the pipeline due to the fact that the pipeline is heavy in weight. Traditional portal frame adopts the steel pipe channel-section steel welding to form, and volume weight is great, and the artifical transport of upper and lower slot is hard still needs mechanical assistance, causes artifical mechanical cost height, inefficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel simply assemble over-and-under type portal frame.

In order to achieve the above object, the utility model provides a following technical scheme: a novel simple assembling lifting portal frame comprises a cross beam, a stand column and a base; a vertical mounting pipe is fixedly arranged on the base, the upright post is movably inserted in the vertical mounting pipe along the vertical direction, a plurality of positioning holes are formed in the side part of the vertical mounting pipe along the vertical direction, a plurality of slots are formed in the side wall of the upright post along the axial direction, and the positioning holes are aligned with the slots and then inserted with pins to lock the upright post; the two ends of the beam are fixedly connected with the upper ends of the upright posts.

Furthermore, the cross beam, the upright post and the base are all formed by welding channel steel, steel pipes and steel plates. Simple structure and low cost.

Furthermore, the lower end of the cross beam is provided with a first connecting flange, the upper end of the stand column is provided with a second connecting flange, and the first connecting flange and the second connecting flange are fixedly connected through bolts. Through first flange and second flange joint, stress is concentrated for minimumly, and intensity is high, and bearing capacity strengthens, simple structure, easy dismounting.

Furthermore, a plurality of reinforcing diagonal rods are uniformly distributed on the vertical installation pipe in the circumferential direction, the upper ends of the reinforcing diagonal rods are fixedly connected with the outer side wall of the vertical installation pipe, and the lower ends of the reinforcing diagonal rods are fixedly connected with the base. The connection stability of the vertical installation pipe on the base is improved, deformation is not easy to occur, and the bearing capacity is improved.

Furthermore, the bottom of the base is provided with a supporting roller. The portal frame is convenient to move.

The technical effects of the utility model are as follows: novel simply assemble over-and-under type portal frame adopts height-adjustable assembly methods, and the installation is dismantled conveniently, has overcome and has adopted traditional portal frame heaviness, artifical mechanical cost height, inefficiency scheduling problem. The construction is assembled fast at the scene to convenient transportation, reduces construction cost for the construction progress reduces the transport construction degree of difficulty, reduce cost, accelerate the progress, guarantee construction safety. The hoisting device can be suitable for hoisting pipelines in the groove, is simple and convenient to transport and install, greatly reduces the construction difficulty, achieves the aims of reducing the construction cost, accelerating the construction progress and ensuring the construction safety, has considerable economic and social benefits, and accumulates experience for the same type of engineering.
