Embodiment 1

[0071] Such as figure 1 and figure 2 As shown, the half-gantry scraper reclaimer of the present embodiment includes,

[0072] Half gantry 1, which is placed above the stockyard 1000;

[0073] Walking system 2, which includes an upper traveling mechanism 20 and a lower traveling mechanism 21, which are respectively connected to the upper end beam 10 and the lower end beam 11 of the half mast 1;

[0074] Reclaiming system 3, which is located under the half-gantry 1, and reclaims materials through scrapers;

[0075] The unloading system 4, which is located next to the lower end beam 11 of the semi-gantry 1, receives and unloads the materials output by the reclaiming system 3;

[0076] Pitching system 5, which is set on the semi-gantry 1 and is connected to the reclaiming system 3 in transmission, to control the lifting of the reclaiming system 3;

[0077] The upper traveling mechanism 20 is movably connected with the upper end beam 10 of the half mast 1 through a spherical f...

Embodiment 2

[0081] Such as figure 1 and figure 2 As shown, the semi-gantry scraper reclaimer of the present embodiment is further improved on the basis of Embodiment 1, the traveling system 2 is driven by a plurality of motors 22, and the upper traveling mechanism 20 is driven by two motors 22 drive, the lower traveling mechanism 21 is driven by four motors 22, and all motors 22 are driven by a variable frequency drive.

[0082] The applicant found that the two traveling mechanisms connected to the two end beams of the semi-gantry 1 received different loads from the gravity of the semi-gantry 1, and the load on the lower traveling mechanism 21 was greater than that on the upper traveling mechanism 20. The load is much larger, which causes the power loss of the two traveling mechanisms to be different when driving, which will cause the displacement speeds of the beams at both ends of the half-gantry 1 to be inconsistent when moving, and also cause the half-gantry 1 to gnaw to death. 1. ...

Embodiment 3

[0084] Such as image 3 with Figure 4 As shown, the half-gantry scraper reclaimer of this embodiment is further improved on the basis of Embodiment 2, and the half-gantry 1 is composed of an upper end beam part 100, an upper end beam upper part 111 and a lower end beam lower part 110 in sequence. , Welding and fixing between adjacent parts.

[0085] Due to the large structural size of the half-gantry 1, transportation and on-site installation are relatively difficult. The structure of the half-gantry 1 in this embodiment is composed of three-stage assembly, which can effectively reduce the difficulty of installation and transportation of the half-gantry 1. 1 The three-stage structure is a sealed box structure, which can reduce the weight and prevent dust from entering and accumulating. After the adjacent parts are connected by high-strength bolts and connecting plates, they are welded and fixed, thereby ensuring the stability of the connecting structure.

Abstract

The invention discloses a half-portal scraper reclaimer, and belongs to the field of mechanical conveying equipment. The half-portal scraper reclaimer comprises a half portal, a walking system, a material reclaiming system, an unloading system and a pitching system, wherein the half portal is placed above a stockyard, the walking system comprises an upper walking mechanism and a lower walking mechanism which are connected with an upper end beam and a lower end beam of the half portal correspondingly, the material reclaiming system is located below the half portal and performs material reclaiming through a scraper, the unloading system is located beside the lower end beam of the half portal and receives and discharges a material output from the material reclaiming system, the pitching system is arranged on the half portal and in transmission connection with the material reclaiming system and controls the material reclaiming system to rise or fall, and the upper walking mechanism is movably connected with the upper end beam of the half portal through a spherical fixing hinge support. The upper walking mechanism is connected with the upper end beam through the spherical fixing hinge support, the stress caused to equipment by nonlinear errors generated on the end beams in the moving process of the half portal can be compensated for through the spherical fixing hinge support, and therefore the rail gnawing or seizing phenomenon is avoided, and the material reclaiming efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mechanical conveying equipment, and more specifically relates to a half-gantry scraper reclaimer. Background technique [0002] The raw material field for the half-gantry scraper reclaimer is an indoor closed layout, which can effectively prevent dust. It is a typical application in the steel industry and meets the current national strict requirements for environmental protection. The half-gantry scraper reclaimer The semi-gantry structure straddles the material pile and walks along the material pile, relying on the scraper chain on the cantilever mechanism of the reclaimer to run continuously, the material is scraped from the surface of the material pile layer by layer by the scraper, and the scraped material passes through a The unloading hopper is conveyed to the transport mechanism arranged along the edge of the pile. When the scraper scrapes the material from the pile, the walking system continuously drives th...
