Abstract
A non-gravity balance lifter resolves the problems of prior art as inaccurate positioning, large energy consumption and serious abrasion on machine. The utility model is characterized in that based on the structure of prior balance lifter, in a box body (1), a lead screw (7) and a smooth rod (8) are symmetry arranged with a large arm (12), the rod (8) is parallel with the lead screw (7), the lead screw (7) and the rod (8) are arranged with counterbalance (5), a nut (6) is arranged between the counterbalance (5) and the lead screw (7), and a bearing (10) is arranged between the box body (1) and the lead screw (7). The non-gravity balance lifter has the advantages of simple structure, accurate positioning, easy operation, low energy consumption, low abrasion, large power and high safety, with wide application for different conditions.
Description
Technical field:
The utility model belongs to the technical field of machine manufacture, is specifically related to a kind of agravic balance crane.
Background technology:
Known to the contriver, at present the general-duty balance crane can only be a balance on horizontal surface mostly, relies on motor drives during lifting, and it is inaccurate to have a location, and work is inconvenient, and power consumption is big, the defective that the body wearing and tearing are big.
Summary of the invention;
For overcome above deficiency, work conveniently exactly by a kind of accurate positioning that provides for the purpose of this utility model, and it is little to consume energy, and the body wearing and tearing are little, and can adapt to the agravic balance crane of managing the environmental balance lifting variously.
The utility model is to realize like this, the structure of described agravic balance crane is the casing (1) that a square body unfilled corner is set earlier, mandrel (2) is set in casing (1), be nested with an axle sleeve (3) at mandrel (2), be connected with axle sleeve (3) root post (4) is set, column (4) setting is connected by front-wheel (17), middle wheel (18), on the mobile vehicle frame that trailing wheel (19) and handle (15) and handle (16) are formed, on casing (1) internal axle sleeve (3), be connected with middle arm (13), be provided with forearm (14) at the following base angle of casing (1), big arm (12) is arranged on another termination of middle arm (13) and forearm (14), motor (11) is arranged on the last top of casing (1), captive joint with belt pulley (9) belt on being arranged on leading screw (7), it is characterized in that in casing (1), being symmetrically arranged with leading screw (7) and polished rod (8) with big arm (12), polished rod (8) be arranged in parallel with leading screw (7), leading screw (7) is provided with counterweight (5) with polished rod (8), be provided with screw (6) between counterweight (5) and the leading screw (7), between casing (1) and leading screw (7), also be provided with bearing (10).Agravic balance crane of the present utility model is to utilize lever principle, realizes weight balancing by mobile counterweight front and back position and institute's hoisting thing, and support body is steady, carries with have gentle hands article are sling.
It is simple in structure, easy to operate to adopt agravic balance crane of the present utility model to have, accurate positioning, and work is convenient, and it is little to consume energy, and the body wearing and tearing are little, and can adapt to the advantage of managing the environmental balance lifting variously.
