Abstract
The utility model discloses a novel structure connecting a protective guard and crossbeams of a tractor, which comprises the protective guard and the crossbeams. The structure is characterized by further comprising two support plates and channel sections. The two support plates which are both U-shaped bending pieces are symmetrically equipped between the protective guard and the crossbeams. One upper parallel side of each support plate is welded on the lower part of the protective guard while one lower parallel side of each support plate is respectively in contact with the upper part of one crossbeam. The channel sections arranged in an inclined way simultaneously contact the crossbeams and the support plates. Bolts are screwed by double nuts after passing through the support plates and the channel sections. A wedge-form clamping way is adopted in the utility model to support and fix the protective guard on the crossbeams of the tractor. The fixation process which is not limited by the positions of holes on the side surfaces of the crossbeams further requires no punching on the upper planes of the crossbeams. The bolts and the nuts are applied for direct fixation. The connecting structure in the utility model has the advantages of simple production, convenient operation and easy installation. Meanwhile, the connecting structure poses no damage to the crossbeams of an original chassis and casts no influence on the overall strength of the crossbeams. Therefore, the connecting structure further has the advantages of safety, reliability and strong universality.
Description
Technical field
The utility model relates to the chassis ridgepole of tractor truck and the coupling mechanism between the guard rail support.
Background technology
In tractor truck, usually the connecting mode that installs additional of guard rail has two kinds: a kind of is to utilize the hole of big beam sides itself or punch again in its side, because the stationkeeping and the quantity in hole are few, and survey precision requires height, has brought great difficulty to making; Because it is optional features such as the gas cylinder of crossbeam side arrangement, storage battery, fuel tank, spare tyre are very many, dry and astringent with it simultaneously through regular meeting, so also there is limitation the position; Another kind is the mode that adopts plane punching on crossbeam, and this connecting mode degree of freedom is big, and alternative place is many, and shortcoming is the bulk strength that can have a strong impact on crossbeam, causes the serious consequence of crossbeam in punching place fracture easily.
Summary of the invention
Problem to be solved in the utility model provides a kind of novel draw bail between guard rail and the crossbeam, makes to connect conveniently rapidly, and is safe and reliable.
The novel draw bail of the guard rail of the utility model tractor truck and crossbeam comprises guard rail, crossbeam, it is characterized in that: further comprising support plate, channel-section steel; Support plate has two, is U type bending part, is arranged on symmetrically between guard rail and the crossbeam; A top parallel edges of support plate be welded on guard rail below, below it parallel edges with contact above the crossbeam, tilted-putted channel-section steel contacts with crossbeam, support plate simultaneously, bolt passes the back with double nuts and tight from support plate, channel-section steel.
The utility model is to adopt the wedge shape clamping mode, and guard rail is supported and fixed on the tractor truck crossbeam, is not subjected to the position limit of crossbeam lateral aperture also to need not on crossbeam the plane and punches, and directly uses bolt, nut and tight.This novel production is simple, easy to operate, is easy to install.Simultaneously, the crossbeam on former chassis is not had damage, can not influence the bulk strength of crossbeam, therefore safe and reliable and highly versatile.
Description of drawings
Now the utility model will be further described with the specific embodiment in conjunction with the accompanying drawings:
Fig. 1 is the chassis ridgepole of this novel traction car and the coupling mechanism assembling scheme drawing between the guard rail support.
The specific embodiment
The novel draw bail of the guard rail of the utility model tractor truck and crossbeam comprises guard rail 5, crossbeam 1, it is characterized in that: further comprising support plate 2, channel-section steel 4; Support plate 2 has two, is U type bending part, is arranged on symmetrically between guard rail 5 and the crossbeam 1; A top parallel edges of support plate 2 be welded on guard rail 5 below, below it parallel edges with contact above the crossbeam 1, tilted-putted channel-section steel 4 contacts with crossbeam 1, support plate 2 simultaneously, and it is also tight with double nuts that bolt passes the back from support plate 2, channel-section steel 4.Channel-section steel 4 wherein is U type bending part or is the section bar channel-section steel.
In order further to increase the single-piece Joint strenght, support plate 2 is welded with stay bearing plate 3 between two parallel limits.
The utility model is that channel-section steel 4 adopts the wedge shape clamping mode by support plate 2 guard rail 5 to be supported and fixed on the tractor truck crossbeam 1, its horizontal spacing longitudinally of Field adjustment, guarantee not interfere, and guarantee when channel-section steel 4 is installed cell cover to open without hindrance with other parts of crossbeam 1.After the position of channel-section steel 4 is determined, adopt the mode of double nuts, clamp with bolt, other parts such as crossbeam with guard rail 5 are welded again.
The utility model is supported and fixed on guard rail on the tractor truck crossbeam, is not subjected to the position limit of crossbeam lateral aperture also to need not on crossbeam the plane and punches, and directly uses bolt, nut and tight.This novel production is simple, easy to operate, is easy to install.Simultaneously, the crossbeam on former chassis is not had damage, can not influence the bulk strength of crossbeam, therefore safe and reliable and highly versatile.
