The liftable trolley comprises an upper plate, a lower plate and a lifting power mechanism, wherein the lower plate is provided with wheels, symmetric vertical columns are arranged on the upper plate, the support is a rectangular frame with symmetric vertical legs on the bottom surface, and the vertical legs are respectively hinged with the upper ends of the vertical columns. The liftable trolley further comprises an X-shaped folding frame connected between the upper plate and the lower plate with the wheels. The lifting power mechanism comprises a hydraulic cylinder and a piston rod, the hydraulic cylinder is mounted at the bottom of the lower plate with the wheels and is connected with the X-shaped folding frame through the piston rod. The lifting device is fittingly used with a crown block, the height of a bottom door is increased by the lifting power mechanism and the position thereof is adjusted by the liftable trolley, mounting and operation of the bottom door are facilitated by supporting of the trolley, production efficiency is improved, labor intensity is reduced, industrial accidents are reduced, and safety production is guaranteed.
Description
Technical field
The utility model relates to a kind of jacking system that boxcar bottom door is installed, and is applicable to the installation location of goods train carriage bottom door.
Background technology
Bottom door is equipped with in goods train carriage bottom for bulk freight, and its effect is the unloading that facilitates bulk freight.The method that bottom door is installed in prior art is: boxcar is promoted, bottom door is sling with overhead traveling crane and is moved to a side of boxcar, installer moves to bottom door below boxcar, then firmly boxcar bottom door is lifted and withstood in the frame that is placed on bottom door, by installation connecting element, bottom door is connected with the frame of boxcar bottom door.The drawback of the method is: although boxcar elevated height, construction space is below inadequate, and operator also will bend over or semi-crouch operates installation bottom door below, labour intensity is very large, waste time and energy and dangerous, boxcar bottom door puts in place inaccurate, and production efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of jacking system that boxcar bottom door is installed, and has that to load boxcar bottom door quick, and mobile boxcar bottom door accurately puts in place, facilitate that boxcar bottom door installs feature.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of jacking system that boxcar bottom door is installed, is characterized in that: comprise liftable hand barrow and support; Described liftable hand barrow comprises upper strata sweep, with lower floor's sweep and the lifting drive mechanism of wheel, upper strata sweep is provided with symmetrical column; Described support is the rectangular frame that bottom surface is provided with symmetrical vertical leg, and described vertical leg is hinged with the upper end of column respectively.
The further improvement that the utility model is done is: described liftable hand barrow also comprises and is connected to upper strata sweep and with the X-shaped folding stand between lower floor's sweep of wheel, described lifting drive mechanism comprises hydraulic actuating cylinder and piston rod, and described hydraulic actuating cylinder is arranged on the bottom of lower floor's sweep of wheel and by piston rod and is connected with X-shaped folding stand.
The beneficial effect that technique scheme produces is: the utility model and overhead traveling crane are used in conjunction with, bottom door is sling and is placed on the support above liftable hand barrow, by lifting drive mechanism, promote the height of bottom door, by liftable hand barrow, adjust the position of bottom door, operator promotes hand barrow, bottom door is delivered to below boxcar bottom door frame, support due to hand barrow, facilitated bottom door fitting operation, can enhance productivity, reduce labour intensity, reduce accident on duty, guarantee safe production.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
As shown in the figure: the frame of 1 boxcar, 2 boxcar bottom doors, 3 boxcar bottom doors, 4 supports, 5 vertical legs, 6 columns, 7 upper strata sweeps, 8 wheels, the 9 lower floor's sweeps with wheel, 10X shape folding stand ,11 lifting drive mechanism, 12 handlebars.
The specific embodiment
Contrast Fig. 1 is used step to be described further to operation of the present utility model:
The jacking system that boxcar bottom door is installed, is characterized in that: comprise liftable hand barrow and support 4; Described liftable hand barrow comprises upper strata sweep 7, with lower floor's sweep 9 and the 11， of the lifting drive mechanism upper strata sweep 7 of wheel, is provided with symmetrical column 6; The rectangular frame of described support 4 symmetrical vertical leg 5 for bottom surface is provided with, described vertical leg 5 is hinged with the upper end of column 6 respectively.
Described liftable hand barrow also comprises and is connected to upper strata sweep 7 and with the X-shaped folding stand 10 between lower floor's sweep 9 of wheel, described lifting drive mechanism 11 comprises hydraulic actuating cylinder and piston rod, and described hydraulic actuating cylinder is arranged on the bottom of lower floor's sweep 9 of wheel and by piston rod and is connected with X-shaped folding stand 10.
Support 4 and column 6 channel-section steel welding fabrication, support 4 is hinged by semi-finished round pin with the upper end of column 6, and support 4 can stir left and right.Hydraulic actuating cylinder right-hand member is arranged on the bottom with lower floor's sweep 9 of wheel, and its piston rod is connected with X-shaped folding stand 10, utilizes Hydraulic Pump that oil pressure is entered to hydraulic actuating cylinder, then the power of hydraulic actuating cylinder is passed to upper strata sweep 7 by X-shaped folding stand 10, for bay-lift provides power.
The control step of the present embodiment: one, the height of lifting boxcar 1, making has enough fitting operation spaces below it.Two, with the overhead traveling crane boxcar bottom door 3 of slinging, be placed on above support 4, primer fluid press pump, the piston rod of hydraulic actuating cylinder is the frame 2 lower than boxcar bottom door by the height of X-shaped folding stand 11 jack-up rising ，Shi boxcar bottom doors 3.Three, liftable hand barrow is pushed into below the frame 2 of boxcar bottom door.Four, operator enter boxcar 1 below, then adjust the height of lifting table, while substantially reaching setting height(from bottom), then the angle ，Shi boxcar bottom door 3 that manually changes swinging strut enters in the frame 2 of boxcar bottom door, completes installation.
