Abstract
The utility model provides engineering machinery and a protective device which is arranged on a vehicle frame. The protective device comprises a push rod and a protective rail movably connected on the vehicle frame. One end of the push rod is hinged with the protective rail. The other end of the push rod is connected with one of at least two mounting supports arranged on the vehicle frame in a selectable mode. A lower front protective device and/or a lower back protective device of the protective device can be in a working state or a contracting state by changing of the mounting position of the push rod, and accordingly the distance between the protective device and the ground is adjustable, the fact that when an autocrane runs on a road, the autocrane meets requirements of laws and regulations is guaranteed, and passing requirements of special road conditions can be met.

The utility model relates to engineering machinery field, particularly a kind of construction machinery and equipment and protective device.
Background technology
According in rules GB26511 in the front bottom requirement of shelter of commercial vehicle/comm..vehicle and GB11567.2 to the rear lower requirement of shelter of automobile and trailer, car hosit need to be installed front underrun protection device and protecting device for rear lower part.The front protective device of existing vehicle dress, the mounting means of protecting device for rear lower part are to adopt plain bolt connect or directly be welded on vehicle frame, but for car hosit, the operation of need to travelling through be everlasting building site or mine, these local road conditions are relatively poor, high to the crossing ability requirement, common fixed type front underrun protection device, protecting device for rear lower part can affect its crossing ability.
The utility model content
In view of this, the utility model is intended to propose a kind of construction machinery and equipment and protective device, affects the problem of crossing ability to solve the fixed type protective device.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of protective device, be arranged on vehicle frame, described protective device comprises push rod and is movably connected in guard rail on described vehicle frame, and an end and the described guard rail of described push rod are hinged, the other end selectable be arranged on described vehicle frame at least two mounting brackets in one be connected.
Further, be disposed with front mounting bracket, middle mounting bracket and rear mounting bracket on described vehicle frame, the top of described guard rail is connected on described front mounting bracket by bearing pin, described push rod one end is connected to described guard rail bottom by bearing pin, the other end is selectable is connected to described in the middle of on mounting bracket or rear mounting bracket.
Further, when described push rod was connected on described middle mounting bracket, described guard rail was vertical state; When described push rod was connected on described rear mounting bracket, described guard rail rotated to an angle around described front mounting bracket and is contraction state.
Further, described rear mounting bracket is arranged on the position near described vehicle frame middle part, and described front mounting bracket is arranged on the position away from described vehicle frame middle part.
Further, described push rod is connected with described middle mounting bracket or rear mounting bracket by bearing pin or bolt.
Further, described protective device comprises front underrun protection device and/or protecting device for rear lower part.
A kind of construction machinery and equipment, described construction machinery and equipment is provided with above-mentioned protective device.
Further, described construction machinery and equipment is car hosit.
With respect to prior art, the utlity model has following advantage:
(1) front underrun protection device of protective device described in the utility model and/or protecting device for rear lower part can be mode of operation or contraction state by the variation of push rod installation site, and then make protective device and ground distance adjustable, satisfy regulatory requirement in the time of can guaranteeing the car hosit road running also can be satisfied the crossing ability requirement of special road conditions.
(2) push rod of protective device described in the utility model is connected on guard rail and vehicle frame by bearing pin, and is simple in structure, controls convenient and reliable.
Description of drawings
The accompanying drawing that consists of a part of the present utility model is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the described protective device working state structure of the utility model embodiment schematic diagram;
Fig. 2 is the described protective device contraction state of the utility model embodiment structural representation.
Description of reference numerals:
The 1-guard rail, mounting bracket before 2-bearing pin, 3-, mounting bracket in the middle of 4-push rod, 5-, mounting bracket after 6-, 7-vehicle frame.
The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Fig. 1 and Fig. 2 are the relevant drawings of the present embodiment, as shown in FIG., the described protective device of the present embodiment comprises front underrun protection device and protecting device for rear lower part, this front underrun protection device and protecting device for rear lower part mainly are made of guard rail 1, bearing pin 2, front mounting bracket 3, push rod 4, middle mounting bracket 5, rear mounting bracket 6 and vehicle frame 7, guard rail 1 top is connected by bearing pin 2 with vehicle frame 7, and guard rail 1 can be around these bearing pin 2 rotations; Guard rail 1 bottom and push rod 4 is anterior to be connected by bearing pin 2, push rod 4 rear portions and middle mounting bracket 5 or afterwards mounting bracket 6 be connected by bearing pin 2.After being somebody's turn to do, mounting bracket 6 is arranged on the position near vehicle frame 7 middle parts, and this front mounting bracket 3 is arranged on the position away from vehicle frame 7 middle parts.
When the described protective device of the present embodiment is applied on car hosit, when road running, on mounting bracket 5, make guard rail 1 in running order (as shown in Figure 1) in the middle of push rod 4 can being connected to, at this moment guard rail 1 is less with ground distance, avoids dolly to pierce; When car hosit in the building site or mine when travelling, the condition of road surface variation, crossing ability is bad, can be fixed on push rod 4 on rear mounting bracket 6 by bearing pin 2 this moment, the bearing pin 2 of guard rail 1 this moment on front mounting bracket rotates to an angle backwards, make guard rail be in the contraction state (see figure 2), and then the angle of attach of vehicle, departure angle are strengthened, to improve the crossing ability of car hosit.
In other embodiments, the top of this push rod 4 also can be connected with middle mounting bracket 5 or rear mounting bracket 6 by bolt.
Except above-mentioned protective device, the utility model also provides a kind of construction machinery and equipment that is provided with above-mentioned protective device, particularly a kind of car hosit, and the structure of other each several part of this car hosit is with reference to prior art, and this paper repeats no more.
