The adjustment of current reach fork truck gantry mounting support seat mainly ensures by processing and welding precision, but like this to Fabricating machinery, detection and working accuracy cost and all higher to the requirement of operating personal, open shelves due to car body guide groove and produce the excessive problem of tolerance clearance because of welding deformation or Mismachining tolerance, make door frame produce larger rocking in stacking and handling process, affect whole vehicle stability and reliability.
Utility model content
The utility model, in order to solve the problems of the technologies described above, provides a kind of door frame bearing of reach truck, by can protect that positive door frame runs after effectively adjusting with car body gap steadily with reliable.
The technical solution of the utility model is:
A kind of door frame bearing of reach truck, comprise the door frame support body of L shape, the both sides horizontal segment of described door frame support body is arranged with adjustable-side roll wheel assembly, side wheel and adjustable main roller, and the vertical section bottom, both sides of door frame support body is arranged with main roller; Described main roller is positioned at car body guide groove upper surface and moves, and described adjustable-side roll wheel assembly, side wheel and adjustable main roller are positioned at the inside of car body guide groove, moves after the tolerance clearance between synchronous adjustment they and car body guide groove inside face.
Further, described adjustable main roller is arranged in door frame support body by main wheel eccentric shaft, adjusts the gap between adjustable main roller and car body guide groove inside face, and locked by clamp nut by adjustment main wheel eccentric shaft.
Further, described side wheel is arranged in door frame support body by side wheel eccentric shaft, adjusts the gap between adjustable main roller and car body guide groove inside face, and locked by clamp nut by adjustment side wheel eccentric shaft.
Described adjustable-side roll wheel assembly comprises and carries out by bearing pin and the bearing be installed in door frame support body the draw-in groove that is connected, is arranged with adjustable-side roller in described draw-in groove; The described draw-in groove back side is connected with the adjusting bolt for adjusting gap between adjustable-side roll wheel assembly and car body guide groove inside face.
Described adjustable-side roll wheel assembly, side wheel are each two right, and it is staggered is arranged symmetrically on the both sides horizontal segment of door frame support body.
Door frame support body and roller and annex become one by the utility model, and 1 pair of main roller is arranged symmetrically in the vertical section lower end of the both sides of door frame support body, and another is arranged symmetrically in the horizontal segment end of door frame support body both sides to adjustable main roller.The horizontal segment intermediate symmetry of door frame support body is provided with 2 pairs of adjustable-side roll wheel assemblies and 2 pairs of side wheels.Thus the tolerance clearance adjustment making door frame support body can synchronously realize on 4 directions up and down in car body guide groove, ensure that stationarity when door frame bearing is movable in car body guide groove and reliability, namely can solve and open shelves due to car body guide groove and produce the excessive problem of tolerance clearance because of welding deformation or Mismachining tolerance, avoid door frame to produce larger rocking in stacking and handling process, affect whole vehicle stability and reliability.
So door frame bearing of the present utility model improves the stability of door frame in movable process; And because adjustable main roller, side wheel and adjustable-side roll wheel assembly all have adjustability, the tolerance clearance between they and car body guide groove can be regulated, thus ensure that door frame stability and reliability in the course of the work; And improve equipment adjustment efficiency, ensure the reliability of product.In addition, this door frame bearing all has convenient-to-running feature in adjustment, dismounting and maintenance, is convenient to replaceability operation especially.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model and car body guide groove assemble schematic diagram.
In figure: 1-door frame support body, 2-main roller, 3-adjustable-side roll wheel assembly, 3-1 draw-in groove, 3-2 adjustable-side roller, 3-3 bearing pin, 4-bearing, 5-side wheel, the adjustable main roller of 6-, 7-side wheel eccentric shaft, 8-adjusting bolt, 9-main wheel eccentric shaft, 10-car body guide groove, 11-wear-resistant pad.
Detailed description of the invention
As shown in Figure 1, a kind of door frame bearing of reach truck, comprise the door frame support body 1 of L shape, the both sides horizontal segment of described door frame support body 1 is arranged with adjustable-side roll wheel assembly 3, side wheel 5 and adjustable main roller 6, and the vertical section bottom, both sides of door frame support body 1 is arranged with main roller 2;
