The collapsible ceiling comprises a ceiling support, wherein the ceiling support is respectively hinged with one ends of a ceiling folding arm A and a ceiling folding arm B; the other ends of the ceiling folding arm A and the ceiling folding arm B are both hinged with a connecting arm, the connecting arm is fixedly connected with a canvas supporting frame, the ceiling support is also hinged with one end of an air spring, and the other end of the air spring is hinged with the middle of the ceiling folding arm A. The collapsible ceiling provided by the utility model has the advantages that the operation process is labor-saving and convenient and the requirements when the milling machine is positioned in multiple states can be met.

Description

The collapsible ceiling of pavement milling machine

Technical field

This patent belongs to field of road engineering machinery technical field, particularly relates to the collapsible ceiling of a kind of pavement milling machine.

Background technology

Existing pavement milling machine, ceiling is integral frame structure mostly, is bolted on vehicle frame.In transportation, for reducing complete machine height, ceiling need to be placed into extreme lower position or disassemble, increased so much unnecessary work; In addition available frame structure ceiling is too heavy, and unloading process is wasted time and energy.In addition,, when milling machine is when parking stops out of doors for a long time, existing fixed ceiling cannot be avoided the invasion and attack of rainwater to operating desk and maneuvering area.

Summary of the invention

This patent provides a kind of pavement milling machine collapsible ceiling for solving the technical problem existing in known technology, and this collapsible ceiling rapid operation, convenience, can meet the needs of milling machine when various states.

The collapsible ceiling of pavement milling machine, comprises ceiling bracket,

Hinged with one end of the folding bracelet of ceiling and ceiling folding arm second respectively in described ceiling bracket, it is all hinged with linking arm that ceiling folds the other end of bracelet, ceiling folding arm second, on linking arm, be fixedly connected with canvas bracing frame, in described ceiling bracket, be also hinged with one end of air spring, the middle part of the folding bracelet of the other end of air spring and ceiling is hinged.

This patent can also be by the following technical solutions:

Preferably, be also provided with steady pin in described ceiling bracket, described steady pin passes ceiling bracket and sells in the folding bracelet of ceiling.

Advantage and good effect that this patent has are:

Because this patent adopts technique scheme, by ceiling bracket, the folding bracelet of ceiling, ceiling folding arm second and linking arm, form a quadric chain, under the booster action of air spring, make the expansion of pavement milling machine ceiling and the work of packing up become easily, facilitate, can meet milling machine and normally work, transport and the multiple needs of long-time outdoor parking.

Accompanying drawing explanation

Fig. 1 is the structural representation under the present invention in working order;

Fig. 2 be the present invention at ceiling the structural representation under self-locking critical condition;

Fig. 3 is the structural representation of the present invention under the complete folded state of ceiling.

In figure: 1, ceiling bracket; 2, the folding bracelet of ceiling; 3, ceiling folding arm second; 4, linking arm; 5, canvas bracing frame; 6, air spring; 7, steady pin.

The specific embodiment

For further understanding innovation and creation content, the Characteristic of this patent, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

As shown in Figure 1, the collapsible ceiling of a kind of pavement milling machine, comprise ceiling bracket 1, hinged with one end of the folding bracelet 2 of ceiling and ceiling folding arm second 3 respectively in ceiling bracket, it is all hinged with linking arm 4 that ceiling folds the other end of bracelet, ceiling folding arm second, on linking arm, be fixedly connected with canvas bracing frame 5, be also hinged with one end of air spring 6 in ceiling bracket, the middle part of the folding bracelet of the other end of air spring and ceiling is hinged.

In ceiling bracket, be also provided with steady pin 7, steady pin passes ceiling bracket and sells in the folding bracelet of ceiling.

The operating principle of this patent is:

As shown in Figures 1 to 3, under normal operation condition, the folding bracelet 2 of ceiling and ceiling folding arm second are in vertical state, and air spring 6 is without pressure, and canvas bracing frame 5 is positioned at highest order, by steady pin 7, are sold into the folding bracelet of ceiling and are kept this state; Under state shown in Fig. 2, air spring 6 is in most compressed state; When continuing to decline; surpass after the state shown in Fig. 2; under the state shown in Fig. 3; because air spring starts after by dead point to extend; now just cover instrument desk and seat; so the folding bracelet 2 of ceiling and ceiling folding arm second 3 are positioned at extreme lower position, ceiling integral body, in stable state, is protected instrument desk and maneuvering area when parking stops out of doors.

Although by reference to the accompanying drawings the preferred embodiment of this patent is described above; but this patent is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under the enlightenment of this patent; not departing from the scope situation that this patent aim and claim protect, can also make a lot of forms, within these all belong to the protection domain of this patent.

Claims (2)

1. the collapsible ceiling of pavement milling machine, comprises ceiling bracket, it is characterized in that:

Hinged with one end of the folding bracelet of ceiling and ceiling folding arm second respectively in described ceiling bracket, it is all hinged with linking arm that ceiling folds the other end of bracelet, ceiling folding arm second, on linking arm, be fixedly connected with canvas bracing frame, in described ceiling bracket, be also hinged with one end of air spring, the middle part of the folding bracelet of the other end of air spring and ceiling is hinged.

2. the collapsible ceiling of pavement milling machine according to claim 1, is characterized in that: in described ceiling bracket, be also provided with steady pin, described steady pin passes ceiling bracket and sells in the folding bracelet of ceiling.
