The utility model is characterized in that a truck drive mechanism and a lifting mechanism share one internal combustion engine as a power source, and a hydraulic top cylinder is adopted to support and return the lever arm type lifting mechanism, and the utility model has the advantages of simple structure of an integral truck, correspondingly low cost, and convenient operation.

Description

The hand-held design hydraulic lift truck

The utility model relates to a kind of hand-held design engineering-use vehicle, and especially a kind of taking blame for others by hydraulic pressure supported the answer arm-type mechanism of lever and made this vehicle and lifting weight drop on four novel elevating mechanisms on the feet.

Each model elevator in the past, all be by the large combustion machine travel, though because of its preceence being arranged, manufacturing cost height, mechanism's complexity, machine operation flexibility of operation deficiency, comformability and operation are subjected to the restriction of this body structure, and it is single to manage the operation channel, the cost height, operation is tired, can not bring economical and practical and flexible to operation effect to the user.

The purpose of this utility model is: providing a kind of is traction power with the compact internal combustion engine, drive oil pump pump oil and take blame for others to all hydraulic pressure, and then pushing tow supports the answer arm-type mechanism of lever and make this vehicle and lifting weight drop on four novel elevating mechanisms on the hydraulic supporting feet through the electromagnetic type seperating vale.

For achieving the above object, the technical solution of the utility model is: it is by vehicle chassis, combustion engine, the wheel drive force transfer mechanism, the hydraulic pressure bearing support that contacts to earth, compositions such as hydraulic efficiency elevation structure, it is characterized in that: this hydraulic efficiency elevation structure is by the I that takes blame for others, II takes blame for others, hold-down arm I, hold-down arm II, bracket I, bracket I I, strengthen hold-down arm I, strengthen hold-down arm II, manned bench board, electromagnetism seperating vale and corresponding oil pipeline, the control operation platform, ease of Use box and four hydraulic pressure formations such as feet of contacting to earth, by drive belt make the internal combustion engine moving power output shaft on the one hand with wheel drive force transfer mechanism interlock mutually, on the other hand with geared oil pump interlock mutually, in this hydraulic oil pump oil supply loop, be provided with the electromagnetism seperating vale, several oil pipelines are connected between this electromagnetism seperating vale output port and all hydraulic pressure takes blame for others, bracket I I is fixed on the vehicle chassis, the cylinder body of II of taking blame for others is fixed on the bracket I I, but the end of hold-down arm II is reeling with bracket I I top and is connected, the push rod of II of taking blame for others is movable with hold-down arm II and is connected, but the other end of hold-down arm II is reeling with bracket I and is connected, strengthen hold-down arm II for two and lay respectively at hold-down arm II both sides, but an end of strengthening hold-down arm II is reeling with bracket I I and is connected, but the other end is reeling with bracket I and is connected, the cylinder body of I of taking blame for others is fixed in the bottom of bracket I, but the end of hold-down arm I is reeling with bracket I top and is connected, the push rod of I of taking blame for others is movable with hold-down arm I and is connected, the other end of hold-down arm I is connected with manned bench board, but an end of strengthening hold-down arm I also is reeling with bracket I top and is connected, but its other end is reeling with manned bench board and is connected, handling control desk is arranged on the vehicle chassis, and be with the electromagnetism seperating vale and be electrically connected, maneuver box is arranged on the manned bench board, also is with electromagnetic valve to be electrically connected.

Advantage of the present utility model is: adopted the supporting mechanism of hydraulic actuating cylinder pushing tow return type throw of lever, made that whole elevator structure is simple; In addition, the shared same combustion engine of vehicular drive and lifting mechanism can reduce integral vehicle cost greatly.

Below in conjunction with accompanying drawing, introduce an embodiment of the present utility model.

Accompanying drawing 1 is the utility model embodiment transmission of power, hydraulic oil supply unit and vehicle chassis structural representation.

Accompanying drawing 2 is that the utility model embodiment vehicle chassis, supporting mechanism, lifting mechanism fold the status architecture scheme drawing.

Accompanying drawing 3 is the utility model embodiment feet holding state scheme drawings that land.

Accompanying drawing 4 is that the utility model embodiment hold-down arm I stretches the open mode scheme drawing.

Accompanying drawing 5 is that the utility model embodiment hold-down arm II stretches the open mode scheme drawing.

Accompanying drawing 6 is that the utility model embodiment handles control desk panel feature scheme drawing.

Accompanying drawing 7 is birds-eye vieies of the utility model embodiment radical function structure.

The concrete structure of present embodiment constitutes below by the process of manipulating of this embodiment being introduced structure as shown in drawings.

At first, combustion engine 1 starting passes to drop-gear box 4 and geared oil pump 2 by the belt pulley of widening 3 respectively with power, is transmitted by chain 5 by reduction gearbox output shaft to drive rear axles 8 and rotate again, and makes it can be by normal motor vehicle driving by power operation.

After vehicle came to a complete stop, combustion engine worked on, and drove oil pump 2 work, to electromagnetism seperating vale 6, by the output main oil pipe 7 of seperating vale 6, was transferred to the control operation platform by oil pump 2 output machinery oil again, saw Fig. 1.

The first step: supporting leg.Rotary valve arrow on the control operation deck plate is pushed the full application position, spur operating handle 10 downwards, make 12 work of taking blame for others of the hydraulic pressure of four supports in the leg 11, the support of contacting to earth of four spikes, whole vehicle built on stilts (seeing Fig. 2,3).When ground is uneven, can rotate rotary valve 9 and regulate the flexible of each supporting leg, make it to reach the level of whole vehicle.

Second step: launch hold-down arm.When supporting leg 11 is in steady status fully, " rise I " by the button on the operating console I12 that takes blame for others is started working, hold-down arm I13 is upwards propped up desired height; " rise II " by the button on the operating console II14 that takes blame for others is started working, hold-down arm II15 upwards props up desired height, drives hold-down arm I13 simultaneously and upwards further props up, to reach work desired height (seeing Fig. 4,5).

As end-of-job, press button on the control operation platform earlier and " fall II ", the II14 that takes blame for others directly receives, and is returned to state as shown in Figure 4, connects button again and " falls I ", and the I12 that takes blame for others directly receives, and is returned to the state (see figure 3) that hold-down arm all folds.At last the rotation rotary valve on the control operation platform is placed the full application position, boost operating handle 10 then, pack up four supporting legs 11, this moment, whole vehicle can normal powered travel state to return to.

The utility model is equipped with operating case for easy to operate on manned bench board 16, the stretching, extension that the operator who is arranged in manned bench board also can be by this operating case direct control hold-down arm I, II and folding.

In order to increase the stationarity of elevator, be provided with reinforcement hold-down arm II17 in hold-down arm II15 both sides.Be provided with above hold-down arm I13 and strengthen hold-down arm I18, (see figure 7) is strengthened hold-down arm I18 and hold-down arm I13 combined action, makes manned bench board remain vertical state.
