The external frame (14) is fixed on the bottom board (1), the internal frame (13) is fixed on the ceiling, the hydraulic oil cylinder (9) is arranged in the internal frame and the external frame (13, 14), and the cylinder body and the cylinder shaft of the hydraulic oil cylinder are respectively fixed on the internal frame and the external frame (13, 14).
Description
Technical field
The utility model relates to a kind of expanded type compartment, particularly a kind of expanded type compartment with ceiling elevating function.
Background technology
Expanded type compartment with ceiling, rain and sun, convenient moving is suitable for field activity and uses.The domestic expanded type trailer envelope that occurred over the past two years, its ceiling adopts the up-down mode of four column leading screw stage clip mechanisms, and its landing ceiling armrest is swaggered a turn-screw, the tense wire rope compression spring, thereby operation is comparatively painstaking; And, its in storage process, for the release spring stress ceiling that must raise, comparatively inconvenience.At present, for the ceiling lifting in expanded type compartment, employing electric hydaulic up-down mode, its manufacturing cost height; The artificial two oil cylinder hydraulic up-down modes of employing, be easy to generate inclination in the lifting process, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, light, steady safety of lifting of operation and fast speed to have the expanded type compartment of ceiling elevating function.
For achieving the above object, the utility model is achieved by the following technical solutions: a kind of expanded type compartment with ceiling elevating function, comprise: the base plate in compartment and ceiling, and be arranged on lifting device between base plate and the ceiling, it is characterized in that, described lifting device comprises: hydraulic ram, connect the hydraulic oil pump of hydraulic ram by pipeline, but and the inside and outside framework of the sleeve-type of longitudinal sliding motion assembling; Described outside frame is fixed on the base plate, and inner frame is fixed on the ceiling; Hydraulic ram is arranged in the inside and outside framework, and its cylinder body and cylinder axle are separately fixed on the inside and outside framework.
Further characteristics of the present utility model are:
Described inside and outside framework is provided with position-limitting pin, limits the limit hoisting position and the limit landing place of inner frame.
Described hydraulic oil pump is the manual hydraulic oil pump with check valve.
In the utility model, adopt manual hydraulic oil pump and 1 hydraulic ram lifting and landing ceiling, for avoiding occurring tilting in the ceiling lifting process, but the supporting inside and outside framework that has designed the sleeve-type assembling of longitudinal sliding motion plays the lifting guiding function; Inside and outside support is at the end position of a lifting pin of limiting, and prevents that ceiling from unexpected landing occurring in the lifting back that puts in place, and prevents from play up and down to occur after ceiling from dropping to the end in transportation.
Low cost of manufacture of the present utility model is operated lightly, and care and maintenance is simple, lifting and landing process steadily, safety, fast, be particularly suitable for the expanded type compartment that automobile, trailer etc. need have the lifting mode ceiling.
Description of drawings
Fig. 1 is a kind of running condition scheme drawing with expanded type compartment of ceiling elevating function of the present utility model;
Fig. 2 is the rounding state scheme drawing of Fig. 1;
Wherein: 1, base plate; 2, lower side panel; 3, hinge; 4, top board; 5, epipleural; 6; 7, hydraulic oil pump; 8, pipeline; 9, hydraulic ram; 10, carriage; 11, position-limitting pin; 12, handle; 13, inner frame; 14, outside frame.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is done an into detailed description.
With reference to Fig. 1, Fig. 2, a kind of expanded type compartment with ceiling elevating function of the present utility model mainly comprises: basic platform, ceiling and lifting device.In the basic platform, lower side panel 2 opens into horizontal along the hinge 3 of base plate 1 periphery, open lower side panel 2 pivotally attached set squares again, can form big working face together with base plate 1.Ceiling comprises: top board 4, epipleural 5 and outer tarpaulin etc., after ceiling upwards raise by lifting device, epipleural 5 upwards opened about 90 °, struts outer tarpaulin, formed an expansion end face, thereby made interior obtain bigger available height and space.
Lifting device mainly comprises: hydraulic ram 9, and by the hydraulic oil pump 7 of pipeline 8 connection hydraulic rams 9, but and inner frame 13, the outside frame 14 of the assembling of the sleeve-type of longitudinal sliding motion.Outside frame 14 bottom bolt togethers are on the base plate 1 in compartment; Inner frame 13 tops can with top board 4 bolt togethers, fixing with top board 4 again after also can weld brackets 10.Hydraulic ram 9 is vertically installed in the inside of inside and outside framework 13,14, and the top of the bottom of its cylinder body and cylinder axle is fixed on the inside and outside framework by axle 6 respectively.In order to save cost of equipment, hydraulic oil pump 7 adopts the manual hydraulic oil pump with check valve, and equipment is simple, and is easy to operate.
Inside and outside framework 13,14 is provided with position-limitting pin 11, limits the limit hoisting position and the limit landing place of inner frame 13.Be specially: inner frame 13 is provided with upper and lower knock hole, only establish a knock hole on the outside frame 14, in order to limit the limit hoisting position and the limit landing place of inner frame 13, the back appearance is unexpected lands to prevent ceiling to put in place in lifting, and prevents from play up and down to occur after ceiling from dropping to the end in transportation.
When the lifting ceiling, to extract position-limitting pin 1 and tighten the check valve of hydraulic oil pump 7, the handle 12 of hand hydraulic oil pump 7, hydraulic oil be 8 cylinder bodies that are pumped to hydraulic ram 9 by the road, and the driving cylinder axle rises, thereby slowly rises ceiling.After the ceiling lifting put in place, the knock hole that position-limitting pin 11 is inserted the following knock hole of inner frames 13 and outside frame 14 prevented that with the locking ceiling its accident from falling.
During the landing ceiling, extract the check valve that position-limitting pin 11 backs only need be unscrewed hydraulic oil pump 7 gently, the cylinder axle of hydraulic ram 9 slowly descends under the ceiling action of gravity, orders about hydraulic oil 8 hydraulic return oil pumps 7 by the road, thus the slowly land ceiling.After ceiling landing put in place, the knock hole that position-limitting pin 11 is inserted the last knock hole of inner frames 13 and outside frame 14 was with the locking ceiling, prevent in transportation about play.
