Abstract
The utility model relates to an expanding and lifting system for a top part of a carriage, which is characterized in that the expanding and lifting system comprises a main carriage of a vehicle body, wherein the top part of the main carriage is connected with an expanding carriage in a sealing manner through a lifting mechanism, and the expanding carriage is internally embedded into the main carriage; the lifting mechanism comprises four servo motors which are respectively fixed at four corner ends of the inner wall of the main carriage through a motor supporting base; each of the input ends of the servo motors is connected with a monitoring system, the output end of each of the servo motors is connected with a lead screw, and each of the lead screws is supported between the motor supporting bases and the top part of the main carriage through positioning bearings; and each of the lead screw is connected with a floating nut, and each of the floating nuts is connected with the bottom part of the expanding carriage. The expanding and lifting system for the top part of the carriage is simple in structure, ingenious in design, convenient in operation and good in synchronism, and can be widely used on vehicles running on roads and railways.
Description
Technical field
The utility model relates to a kind of jacking system, particularly about a kind of expansion jacking system of car body top.
Background technology
According to national highway, railway transportation requirement, when the dull and stereotyped transportation of railway, the gross vehicle height generally is no more than 3200 millimeters; When road running, the gross vehicle height generally should be controlled at below 4000 millimeters, so as safely, waltz through culvert, bridge, reduce traffic cost.But when need in the compartment, carrying out under the situation of some special operations; The height in compartment must increase could satisfy job requirements, therefore, the expansion lifting mechanism need be set on the compartment; With the height and the space in expansion compartment, guarantee the transportation request of highway, railway simultaneously.In the prior art, that the expansion lifting mechanism of car body top mainly contains is pneumatic, hydraulic pressure, frame mode such as hand, and there is following problem in the said structure mode: pneumatic more with expansion lifting mechanism parts hydraulic structure, it is big to take up room, and structure is complicated; The expansion lifting mechanism of hand cranking structure goes up and down and requires great effort, and the transmission poor synchronization is prone to stuck.
Summary of the invention
To the problems referred to above, the purpose of the utility model provides a kind of simple in structure, and parts are few, and are easy to operate, the car body top expansion jacking system that synchronism is good.
For realizing above-mentioned purpose; The utility model is taked following technical scheme: a kind of car body top expansion jacking system; It is characterized in that: it comprises the main compartment of car body, and the top in said main compartment is through the lifting mechanism expansion compartment that is tightly connected, and said expansion compartment is embedded in the said main compartment; Said lifting mechanism comprises four servomotors, and said four servomotors are fixed on four turning ends of said main compartment inwall respectively through a motor supporting seat; The input end of each said servomotor all connects monitored control system, and the mouth of each said servomotor connects a leading screw respectively, and each said leading screw is supported between the top in said motor supporting seat and said main compartment through location bearing respectively; Connect a captive nut respectively on each said leading screw, each said captive nut all connects the bottom in said expansion compartment.
On each said servomotor one speed reducer is set respectively.
Each said captive nut connects the bottom in said expansion compartment respectively through a support.
The utility model is owing to take above technical scheme; It has the following advantages: 1, the utility model at the top in main compartment through the lifting mechanism expansion compartment that is tightly connected; When needs carry out relevant operation; Can start the expansion compartment through lifting mechanism, will expand the compartment elevates, with height and the working space that increases whole compartment.2, the elevating mechanism of the utility model comprises the servomotor that is separately positioned on four turning ends of main compartment inwall; The output of each servomotor all connects a leading screw that is supported between motor supporting seat and the main car body top; All connect a captive nut on each leading screw, each captive nut all connects the expansion compartment by support; Start servomotor, servomotor drives the leading screw rotation, and leading screw rotates the drive captive nut and moves up or down along leading screw; And then by support drive expansion compartment rise or decline; The control mode synchronism of this kind elevating mechanism is good, simple in structure, and operating maintenance is convenient.The utility model structure is provided with simply ingenious, and is easy to operate, and synchronism is good, can be widely used on highway, the rolling stock.
Description of drawings
Fig. 1 is the utility model integral structure scheme drawing
Fig. 2 is the local enlarged diagram of the utility model lifting mechanism
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
As shown in Figure 1, the utility model comprises the main compartment 1 of car body, and the top in main compartment 1 is through the lifting mechanism 2 expansion compartment 3 that is tightly connected, and expansion compartment 3 is embedded in the main compartment 1.
As shown in Figure 2, the lifting mechanism 2 of the utility model comprises that 21, four servomotors 21 of four servomotors are fixed on four turning ends of main compartment 1 inwall respectively through a motor supporting seat 22.On each servomotor 21 one speed reducer is set respectively; The input end of each servomotor 21 all connects monitored control system (each is not shown among the figure); The mouth of each servomotor 21 connects a leading screw 23 respectively after slowing down, each leading screw 23 is supported between motor supporting seat 22 and 1 top, main compartment through location bearing respectively.Connect a captive nut 24 on each leading screw 23 respectively, be set with a support 25 on each captive nut 24 respectively, the other end of each support 25 all is fixedly installed on the bottom in expansion compartment 3.
In main compartment 1, carry out relevant operation, when needing to start expansion compartment 3, will expand compartment 3 elevates, with height and the working space that increases whole compartment.The concrete operation method of the utility model is: start servomotor 21, servomotor 21 drives leading screw 23 rotations, and leading screw 23 rotations drive captive nut 24 and move up along leading screw 23, and then drives 3 rises of expansion compartment through support 25.Behind the end-of-job, drive leading screw 23 counter-rotatings, fall expansion compartment 3 through servomotor 21.
Above-mentioned each embodiment only is used to explain the utility model; Wherein the structure of each parts, connection mode etc. all can change to some extent; Every equivalents of on the basis of the utility model technical scheme, carrying out and improvement all should not got rid of outside the protection domain of the utility model.
