Abstract
Provided is a goose-head traction mechanical lifting device. The lower portion of the front end of a goose head is provided with a goose-head sliding plate, a screw and nut mechanical lifting assembly is installed between the goose-head sliding plate and the goose head, a traction pin assembly matched with a tractor saddle is installed under the goose-head sliding plate, the goose-head sliding plate is provided with an upward guiding column, and the goose head is provided with a guide sleeve matched with the guiding column. The screw and nut mechanical lifting assembly is arranged between the goose-head sliding plate and the goose head, a screw of the screw and nut mechanical lifting assembly rotatably and simultaneously performs vertical motion and accordingly drives the goose-head sliding plate to perform vertical motion, the guiding column and the guide sleeve play a guiding role on the motion, a goose-head sliding plate plane performs vertical linear motion and does not incline, and a liftable adjustment function of the semitrailer goose-head sliding plate is achieved. Therefore, the semitrailer goose-head sliding plate can be smoothly in hooked connection with different models of tractor saddle planes, and operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of superimposed trailer technical field, particularly a kind of superimposed trailer gooseneck boom trailer-type machine jacking system.
Background technology
Traditional superimposed trailer gooseneck boom slide plate is not liftable.Tractor truck saddle level is consistent with superimposed trailer gooseneck boom slide plate requirement for height, traditional superimposed trailer gooseneck boom slide plate not liftable makes superimposed trailer gooseneck boom slide plate not realize and articulating from different tractor truck saddles, again because superimposed trailer exists scale error and the impact of other various factors in manufacturing process, in practical operation, repeatedly there is the phenomenon that tractor truck and superimposed trailer are done over again because height error does not articulate.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, the gooseneck boom draw gear of hand-operated lifting.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of gooseneck boom trailer-type machine jacking system, in the bottom of gooseneck boom front end, be provided with gooseneck boom slide plate, bolt and nut mechanical elevating assembly is housed between gooseneck boom slide plate and gooseneck boom, the towing pin assembly matching with tractor truck saddle is equipped with in gooseneck boom slide plate below, described gooseneck boom slide plate is provided with guidepost upwards, is provided with the guide pin bushing coordinating with guidepost at gooseneck boom.
Technical problem to be solved in the utility model can also further realize by following technical scheme, described bolt and nut mechanical elevating assembly is contained in the front end of gooseneck boom by bracing frame, bracing frame comprises two crossbeams that be arranged in parallel and two longerons that be arranged in parallel, and longitudinal and cross beam forms a frame mechanism.
Technical problem to be solved in the utility model can also further realize by following technical scheme, support frame as described above is equipped with the nut coordinating with screw rod, the inner side symmetry of bracing frame is equipped with two groups of guide pin bushings, guide pin bushing is connected with bracing frame by gusset piece, fixedly guide pin bushing, makes guidepost do upper and lower vertical line motion.
Technical problem to be solved in the utility model can also further realize by following technical scheme, one end of the screw rod of described bolt and nut mechanical elevating assembly is provided with handle, the other end is provided with bulb ball seat assembly, and the ball seat on bulb ball seat assembly is connected with gooseneck boom slide plate over against towing pin assembly.
The utility model is by establishing bolt and nut mechanical elevating assembly, bolt and nut mechanical elevating assembly is contained between gooseneck boom slide plate and gooseneck boom, handle is established in one end of the screw rod of bolt and nut mechanical elevating assembly, the other end is connected with gooseneck boom slide plate by bulb ball seat assembly, the nut coordinating with screw rod is housed on support frame as described above, during artificial turning handle, drive bolt rotary, the bulb of screw rod one end combines and relatively rotates with ball seat on gooseneck boom slide plate, screw rod is moving up and down vertically rotationally simultaneously, so just driven gooseneck boom slide plate, towing pin assembly moves up and down together, guide pillars and bushes play the guiding role to motion, assurance gooseneck boom slide plate plane is done upper and lower vertical line motion, do not tilt, realized articulating smoothly of gooseneck boom slide plate and tractor truck saddle, compared with prior art, it is reasonable in design, simple to operate, convenient, realized the liftable regulatory function of gooseneck boom slide plate.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model.
Fig. 2 is construction profile schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
See figures.1.and.2, a kind of gooseneck boom trailer-type machine jacking system, bottom at gooseneck boom 1 front end is provided with gooseneck boom slide plate 2, bolt and nut mechanical elevating assembly is housed between gooseneck boom slide plate 2 and gooseneck boom 1, the towing pin assembly 3 matching with tractor truck saddle is housed below gooseneck boom slide plate 2, described gooseneck boom slide plate 2 is provided with guidepost 4 upwards, is provided with the guide pin bushing 5 coordinating with guidepost 4 at gooseneck boom 1.
Described bolt and nut mechanical elevating assembly is contained in the front end of gooseneck boom 1 by bracing frame, bracing frame comprises two crossbeams that be arranged in parallel 7 and two longerons that be arranged in parallel 6, and longeron 6 and crossbeam 7 form a frame mechanism.
Support frame as described above is equipped with the nut 9 coordinating with screw rod 8, and the inner side symmetry of bracing frame is equipped with two groups of guide pin bushings 5, and guide pin bushing 5 is connected with bracing frame by gusset piece 10.
One end of the screw rod 8 of described bolt and nut mechanical elevating assembly is provided with handle 11, and the other end is provided with bulb ball seat assembly, and the ball seat 12 on bulb ball seat assembly is connected with gooseneck boom slide plate 2 over against towing pin assembly 3.
During artificial turning handle 11, drive screw rod 8 to rotate, screw rod 8 one end are connected with gooseneck boom slide 2 by the ball seat 12 on bulb ball seat assembly, screw rod 8 is being done rotationally simultaneously, lower perpendicular movement, so just driven gooseneck boom slide plate 2, towing pin assembly 3 moves up and down together, 5 pairs of motions of guide pillar 4 and guide pin bushing play the guiding role, assurance gooseneck boom slide plate 2 planes are done upper and lower vertical line motion, do not tilt, realized the function that superimposed trailer gooseneck boom slide plate 2 liftables regulate, superimposed trailer gooseneck boom slide plate 2 just can articulate smoothly with the tractor truck saddle plane of different model, simple to operate, convenient.
