Abstract
The invention discloses a counter weight of an aerial work platform. The counter weight of the aerial work platform comprises a welding type shell body, low-density filler and high-density filler, wherein the welding type shell body is centrosymmetric, an inner cavity of the shell body is divided into a plurality small cavities through a plurality of partition plates, the volumes of the small cavities are eudipleural relative to the center of the counter weight, the inner cavity of the shell body is divided into an upper filling area and a lower filling area, the upper filling area and the lower filling area are respectively filled with the low-density filler and the high-density filler in a symmetrical mode, and the gravity center of the counter weight after being filled is centered and close to the lower portion. The counter weight of the aerial work platform uses the design concept of area division and the method of symmetrical filling, achieves that the gravity center of the counter weight after being filled is centered and close to the lower portion under strict control, and greatly improves stability of a complete machine, thereby resolving the technical problem that performance of the complete machine is affected due to unbalance loading of the counter weight and the overhigh gravity center. Meanwhile, the counter weight of the aerial work platform is simple to manufacture, convenient to check and accept, economical and reliable, and has important popularization and application significance.
Description
Technical field
The present invention relates to balancer weight, especially a kind of balancer weight of aerial work platform.
Background technique
Be applied to the high-altitude construction operation from walking straight arm type aerial work platform since the operation amplitude greatly, highly high, require machine to have outstanding complete machine Static and dynamic stability, thereby the effect of balancer weight seems particularly important.Balancer weight is used for the moment that the front section load of balance produces, if center of gravity is too high unfavorable to walking and operation, machine topples easily backward; If left and right sides center of gravity symmetry properties is poor, will produce unbalance loading, behind the revolving dial revolution several angle, a phenomenon that the tire perk is liftoff can occur, cause machine to roll to unbalance loading one easily and cover.
At present, the balancer weight that is installed on the straight arm type aerial work platform of walking mainly is divided into two types: a kind of is one piece casting formula balancer weight, though its position of centre of gravity is controlled, manufacture cost is high, is difficult to apply; Another kind is welding filled type balancer weight, its manufacturing is simple, with low cost, deeply be subjected to the welcome of vast main engine factory, but because the inside of welding filled type balancer weight all is only to be made of a large chamber, and packing is the mixture of multiple different densities material, is difficult to stir fully, so balancer weight weight left-right asymmetry, position of centre of gravity after being easy to cause filling are uncontrollable, thereby affect stability and normal use of complete machine, even have potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of make simple, check and accept convenient, the economic reliably balancer weight of aerial work platform, it belongs to a kind of center of gravity between two parties and the balancer weight of welding fabrication on the lower, filled type, can be widely used on the series product.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: the balancer weight of aerial work platform, comprise welding type housing and low density packing, high density packing, symmetric body centered by the welding type housing, the housing inner chamber is some loculuses by some baffle for separatings, the heavy center of the volume relative equilibrium of these loculuses bilateral symmetry; The housing inner chamber is divided into fill area and lower fill area, symmetrical low density packing and the high density packing of filling respectively, and the center of gravity of the balancer weight after the filling is between two parties and on the lower.
After weight, volume being carried out the calculating of density proportioning, the housing inner chamber is divided into upper fill area and lower fill area.
The low density packing is the concrete of sand, rubble and cement composition, and the high density packing is the mixture that barite, iron powder and concrete form.
Problem for the balancer weight existence that has aerial work platform now, the inventor uses design concept and the symmetrical engineering method of filling of separated region, balancer weight housing inner chamber is separated into the symmetrical some loculuses in the heavy center of volume relative equilibrium, pass through weight again, after volume carries out the calculating of density proportioning, the housing inner chamber is divided into upper fill area and lower fill area, symmetry is filled low density packing and high density packing respectively, the center of gravity that has finally realized the balancer weight after strict control is filled between two parties and on the lower, greatly improved the stability of complete machine, thereby solved because of the balancer weight unbalance loading, center of gravity is too high and affect the technical barrier of overall performance.
Description of drawings

Fig. 2 is the axonometric drawing of welding type housing of the balancer weight of Fig. 1 high and medium working platform.
Fig. 3 is the positive side schematic view of the balancer weight of Fig. 1 high and medium working platform.
Among the figure: 1 welding type housing, 2 low density packings, 3 high density packings, 4 shells, four, 12 times fill areas of 5 dividing plate one, 6 dividing plate, two, 7 dividing plate three, 8 loculuses, one, 9 loculus two, 10 loculuses, three, 11 loculuses, fill area on 13.
Embodiment
As shown in Figures 1 to 3, the balancer weight of the balancer weight aerial work platform of aerial work platform of the present invention comprises welding type housing 1 and low density packing 2, high density packing 3.Symmetric body centered by the welding type housing 1, be welded by shell 4, dividing plate etc., the housing inner chamber is divided into four loculuses (loculus 1, loculus 29, loculus 3 10, loculus 4 11) by three dividing plates (dividing plate 1, dividing plate 26, dividing plate 3 7), the heavy center bilateral symmetry (loculus one is identical with loculus four volumes, and loculus two is identical with loculus three volumes) of the volume relative equilibrium of these loculuses; After weight, volume being carried out the calculating of density proportioning, the housing inner chamber is divided into the different upper fill area 13 of density and lower fill area 12, namely the H1 absolute altitude is lower fill area, and remaining zone (H2-H1) is upper fill area, and so center of gravity can be realized on the lower in the zoning.
The low density packing adopts the concrete of sand, rubble and cement composition, the mixture that the high density packing adopts barite, iron powder and concrete to form.
When loading packing, use symmetrical engineering method of filling, first high density packing 3 is filled into respectively symmetrically and separates in four good loculuses, and only be filled to lower fill area 12, so loculus 1 and loculus 4 11, loculus 29 and loculus 3 10 such as have respectively at the heavy high density packing 3; Fill low density packing 2 supreme fill areas 13 with method.Because respectively symmetrical low density packing 2 and the high density packing 3 of filling, thereby the center of gravity of the balancer weight after filling between two parties and on the lower.
