Abstract
The utility model discloses a manpower vehicle ladder for cast iron pouring is including the frame that is equipped with wheel and handle, still including the staircase that is located frame one side, be connected with the platform of standing that is used for supplying the people to stand between frame and the staircase, be equipped with the guardrail on hand, be equipped with hollow focus adjustment chamber on the supporting legs of staircase bottom, focus adjustment intracavity is equipped with the ball, the external diameter of ball is less than the internal diameter in focus adjustment chamber. The utility model discloses because when the level was placed, the ball was located near center of focus adjustment chamber horizontal direction, and when the car ladder was erect, the ball rolled to the bottom in focus adjustment chamber for holistic focus is steady, and the focus when horizontal migration and erect and place can automatic adjustment, can guarantee personnel safety and stability when standing.
Description
Technical field
The utility model relates to casting technology field, is specially a kind of rickshaw for cast iron ladder.
Background technology
At present, casting shop is in ironcasting casting process, and in order to ensure safety when cast personnel stand when high temperature liquid iron is poured into a mould, general employing overhead traveling crane hangs mobile halfpace and pours into a mould to suitable position.And because overhead traveling crane quantity is few and casting-up place causes halfpace to be not easy practical difficulties such as putting in place because of environmental factor in actual production, cast personnel are worked under sub-safe condition of being everlasting.
The problem of standing to improve cast personnel just need to use a kind of single can the halfpace of convenient movement, the method for employing at present has two kinds: one to be directly buy double ladder; Two is from making light-weighted simple and easy halfpace with reinforcing bar.Above-mentioned two kinds of methods are methods that current most of casting shop adopts, but there is following potential safety hazard in these two kinds of methods: the position that first method is stood narrow equally, the personnel of standing do not have mobile space, affect casting pouring quality, there is the potential safety hazard of tumble injury yet.Second method is in order to allow simple and easy halfpace convenient in carrying, and steel selected during making as far as possible specification are little, and when causing personnel to stand above, stability is poor.
Utility model content
Therefore, in order to overcome the deficiency that prior art exists, the utility model provide a kind of can conveniently moving, simple and safe the ladder of the rickshaw for cast iron completing cast work.
The rickshaw ladder that the utility model is used for cast iron comprises the vehicle frame being provided with wheel and handle, also comprise the staircase being positioned at vehicle frame side, the standing platform for standing for people is connected with between described vehicle frame and staircase, described handle is provided with guardrail, feet bottom described staircase is provided with the centre of gravity adjustment chamber of hollow, be provided with ball in described centre of gravity adjustment chamber, the external diameter of described ball is less than the internal diameter in centre of gravity adjustment chamber.
When the utility model is due to horizontal positioned, ball is positioned at the immediate vicinity of centre of gravity adjustment chamber horizontal direction, when car ladder is erect, ball is rolled into the bottom in centre of gravity adjustment chamber, make overall barycentre steadiness, center of gravity when moving horizontally and erect placement can adjust automatically, safety and stability when can ensure that personnel stand.
After reading the detailed description of the utility model embodiment by reference to the accompanying drawings, other features of the present utility model and advantage will become clearly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is that the utility model erects schematic diagram;
Fig. 2 is the utility model level schematic diagram;
Fig. 3 is the top view of guardrail in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention of the present utility model, the rickshaw ladder that the utility model is used for cast iron is made the following instructions.
Embodiment: a kind of ladder of the rickshaw for cast iron, comprise the vehicle frame 2 being provided with wheel 4 and handle 1, also comprise the staircase 3 being positioned at vehicle frame 2 side, the standing platform 9 for standing for people is connected with between described vehicle frame 2 and staircase 3, described handle 1 is provided with guardrail 10, feet bottom described staircase 3 is provided with the centre of gravity adjustment chamber 7 of hollow, is provided with ball 12 in described centre of gravity adjustment chamber 7, and the external diameter of described ball 12 is less than the internal diameter in centre of gravity adjustment chamber 7.Both sides, described staircase 3 top are provided with the bracing frame 11 extended to vehicle frame 2 direction, and the handrail at support frame as described above 11 top is provided with the centre of gravity adjustment chamber 7 of hollow.
Described vehicle frame 2 bottom is provided with centre of gravity adjustment angle steel 6, and described centre of gravity adjustment angle steel 6 is provided with the adjustment screw rod 5 of multiple up-down adjustment.The shape of described guardrail 10 is arc.
Select section steel manufacture the utility model; first this car ladder level is pushed into cast position; then car ladder is erect; cast personnel climb to standing platform 9 from staircase 3; guardrail 10 or bracing frame 11 can be held up to carry out operation; safety when guardrail 10 can protect personnel to stand; during car ladder horizontal positioned; ball 12 is positioned at the immediate vicinity of centre of gravity adjustment chamber 7 horizontal direction; when car ladder is erect; ball 12 is rolled into the bottom in centre of gravity adjustment chamber 7, makes overall barycentre steadiness, is then rotated down adjustment screw rod 5 to bottommost.After operation completes, cast personnel can facilitate locomotive ladder to parking area.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
