CN2473063Y - Folding safety frame for wheel tractor - Google Patents

Abstract

The utility model relates to a folding safety stand used by the roller tractors, essentially characterized in that the bottom of a doorframe-shaped upper framework is connected to two junction panels respectively, the junction panels are provided with at least three switch ports, the outside of each of the junction panels is provided with a left and a right stay bars which are fixedly and respectively connected to the two junction panels. Thereby, the upper framework can be swept down or stood up by connecting the upper framework to the open holes at different positions on the junction panels, and the height of the safety stand can be adjusted at any time. The utility model is easy to be operated and the passing function of the tractor is improved.

Description

Wheel-tire tractor is with folding relief bracket

The utility model relates to the folding relief bracket that a kind of used with tractor relief bracket, especially wheel-tire tractor are used.

The relief bracket that present wheel-tire tractor is used, it is the one-piece construction that constitutes by whisker boom and the crossbeam that is welded on the whisker boom top, in the accidental roll-over accident of trac., the whisker boom of relief bracket will support trac., for the clearance zone of chaufeur provides a protective zone.But because trac. has been installed the relief bracket of one-piece construction, make the trac. whole height increase, cause the trac. through performance to descend, by culvert or go into the place that garage etc. has certain altitude to place restrictions on, usually need the relief bracket overall pulling down, use very inconvenient.

The purpose of this utility model provides a kind of easy to use, is convenient to adjust the wheel-tire tractor of relief bracket height with folding relief bracket.

The utility model is that the technical scheme that achieves the above object is: its bottom of upper frame that is doorframe shape is contained in respectively on two connecting panels, have on the connecting panel and three above mounting holes of upper frame bonded assembly, the outside has the left strut of main frame connecting panel to captive joint with two connecting panels respectively with right strut.

The utility model adopts the advantage of technique scheme to be: because relief bracket is to be connected and composed by connecting panel by upper frame that is doorframe shape and left and right strut, and mounting hole more than three is arranged on the connecting panel, so upper frame is by being connected with the mounting hole of diverse location on the connecting panel, upper frame was fallen or erect, become the folding structure, thereby by regulating the connection location of upper frame and connecting panel, at any time adjust the height of relief bracket, use easy to operately, improved the through performance of trac..

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the schematic side view of Fig. 1.

Fig. 3 is tractor mounted structural representation.

Wheel-tire tractor shown in Fig. 1～2 is with folding relief bracket, upper frame 1 its bottom that is doorframe shape is installed in respectively on two connecting panels 4, mounting hole more than three is arranged on the connecting panel 4, this mounting hole except that one be often with being connected of upper frame 1, all the other are connected with upper frame 1 according to service condition, or/and lock pin is connected the location with two mounting holes on the connecting panel 4, upper frame 1 puts down when being connected then with mounting hole below the connecting panel 4 by tie bolt in upper frame 1 bottom as shown in Figure 2; Being connected then with mounting hole above the connecting panel 4, upper frame 1 erects.For ease of operation, the bottom of upper frame 1 also is provided with a block 11 on the connecting panel 4.The left strut 5 and the right strut 8 of outside welding main frame connecting panel 7 are fixedly connected on two connecting panels 4, and 7 of main frame connecting panels are bolted to connection on the semiaxis housing of wheel-tire tractor.Therefore upper frame 1 is connected the position of connecting panel 4 different mounting holes, and realizes adjusting the height of relief bracket, and is easy to use.

For improving the bulk strength of relief bracket, its two face down bonding of the bottom of upper frame 1 has brace panel 2, and its two side of the top of left strut 5 and right strut 8 also is welded with brace panel 6.

For ease of tilt is installed on relief bracket, positive fluffy attaching parts 10 is arranged on the entablatrance of upper frame 1, its column is provided with socket 9.

Claims (3)

1, a kind of wheel-tire tractor is with folding relief bracket, it is characterized in that: its bottom of upper frame (1) that is doorframe shape is contained in respectively on two connecting panels (4), have on the connecting panel (4) and three above mounting holes of upper frame bonded assembly, the outside has the left strut (5) of main frame connecting panel (7) to captive joint with two connecting panels (4) respectively with right strut (8).

2, wheel-tire tractor according to claim 1 is with folding relief bracket, and it is characterized in that: bottom two face down bondings of upper frame (1) have brace panel (2), and its two side of top of left strut (5) and right strut (8) also is welded with brace panel (6).
