Description
Technical field
The utility model belongs to heavy-duty engine accessory technical field, relates in particular to a kind of loaded vehicle fine motion running gear.
Background technology
Heavy-duty vehicle is when mobile during especially unpowered movable parking berth, by power traction, the fine motion that realizes vehicle by push-and-pull by many people realizes, but is no matter everybody's push-and-pull or power traction because the negative interaction of its inertia very is obviously difficult to realize berth accurately.
Utility model content
The purpose of this utility model is just to provide a kind of for carrying out the effortless loaded vehicle fine motion running gear of arbitrarily realizing the accurate berth of heavy-duty vehicle car advance and retreat walking by artificial.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A loaded vehicle fine motion running gear,
Comprise being arranged in heavy-vehicle wheels and outer rim is provided with the coaxial ratchet of ratchet, and be hinged with frame on the lazy axle of described wheel, the end of this frame is provided with handle fork;
In described frame, by ratchet bearing pin, be fixed with the ratchet with three sour jujube pin that can swing; Wherein, upper and lower two sour jujube pin can snap in respectively in described ratchet ratchet, are provided with spring pin second on drift angle sour jujube pin, and in this spring pin second and described detent pin, cover has quadrangle circlip, in described frame, be provided with spring pin first, between this spring pin first and described circlip, be provided with extension spring.
In addition, the additional technical feature that forms above-mentioned a kind of loaded vehicle fine motion running gear also comprises:
---described quadrangle circlip is the combination of upper and lower two equicrural triangles;
---the upper leg-of-mutton waist length of side of described upper and lower two equicrural triangles is in described lower leg-of-mutton waist limit;
---described frame is that two clamping plate that are socketed on described ratchet both sides form, and wherein, described ratchet is fixed between two clamping plate;
---on described ratchet, be provided with and stir handle.
A kind of loaded vehicle fine motion running gear provided by the utility model compared with prior art has the following advantages: utilize hand fixed handle fork can realize the small mobile berth of heavy-duty vehicle, save labor and walk freely and the accurate feature in position, berth.
Accompanying drawing explanation
Fig. 1: be the structural representation of loaded vehicle fine motion running gear;
Fig. 2: the structural representation while retreating for loaded vehicle fine motion running gear.
The specific embodiment
Below in conjunction with accompanying drawing, the concrete structure of a kind of loaded vehicle fine motion running gear provided by the utility model is described further.
As shown in Figure 1, 2, be the structural representation of a kind of loaded vehicle fine motion running gear provided by the utility model.Be that the structure of fine motion running gear comprises and is arranged on heavy-duty vehicle 1 wheel and outer rim is provided with the coaxial ratchet 3 of ratchet 2, on the lazy axle 4 of wheel, be provided with frame 5, the end of this frame is provided with can wiggly handle fork 15, and this handle fork drives frame end to rotate around the lazy axle 4 of wheel by waving; In above-mentioned frame, by ratchet bearing pin 6, being fixed with can be around upper and lower and three the sour jujube pin of drift angle 7,8 of having of its swing and 9 and stir the ratchet 10 of handle 16; Wherein, upper and lower two sour jujube pin 7,8 can snap in respectively in described ratchet ratchet when ratchet bearing pin 6 swings, on drift angle sour jujube pin 9, be provided with spring pin second 11, on this spring pin second and ratchet bearing pin, cover has the combination quadrilateral circlip 12 of upper and lower two equicrural triangles, in frame, be provided with spring pin first 13, between this spring pin first and circlip, be provided with extension spring 14.
Its principle of work is: when needs by heavy-duty vehicle to micro-while shifting to a berth left along arrow A direction, as shown in Figure 1, first by stirring handle 16, the upper sour jujube pin 7 of ratchet is snapped in ratchet ratchet 17, rear crank handle fork 15 swings left along arrow A, the upper sour jujube pin 7 by frame 5 ratchet bearing pins 6 promotes ratchet, to ratchet 3 is rotated counterclockwise, to realize the berth of minute movement; When needs by heavy-duty vehicle to micro-while shifting to a berth to the right along arrow B direction, as shown in Figure 2, first by stirring handle 16, the lower sour jujube pin 8 of ratchet is snapped in ratchet ratchet 18, rear crank handle fork 15 swings to the right along arrow B, the lower sour jujube pin 8 by frame 5 ratchet bearing pins 6 promotes ratchet, to ratchet 3 is clockwise rotated, to realize the berth of minute movement to the right.In said structure, on spring pin second and ratchet bearing pin cover to have 12 of the combination quadrilateral circlips of upper and lower two equicrural triangles be for to snapped in ratchet ratchet 17(or ratchet ratchet 18) upper sour jujube pin 7(or lower sour jujube pin 8) and fixing, make 6 of snapped in ratchet ratchet, drift angle sour jujube pin 9 and ratchet bearing pins form firm triangles, be convenient to sour jujube pin 7(or lower sour jujube pin 8) promotion to snapped in ratchet ratchet; The extension spring 14 arranging between spring pin first and circlip is for swinging up and down fixing displacement after at ratchet around its bearing pin 6 to circlip 12.
In forming the structure of above-mentioned a kind of loaded vehicle fine motion running gear:
For quadrangle circlip can be played snapped in ratchet ratchet 17(or ratchet ratchet 18) in upper sour jujube pin 7(or lower sour jujube pin 8) fixing, form more firm three-legged structure, lower leg-of-mutton waist limit 20 is longer than on the upper leg-of-mutton waist limit 19 that forms quadrangle circlip;
---more firm for the frame that makes to form, and there is enough intensity, make reasonable integral structure simultaneously, frame is that two clamping plate 21 and 22 that are socketed on ratchet both sides form, and ratchet is fixed between two clamping plate.
