Description
Technical field
This utility model relates to a kind of transport section of Mini-tower hoist tool, and particularly a kind of cocked trailer of Mini-tower hoist tool, belongs to hoisting crane manufacturing technology field.
Background technology
Tower crane (tower crane) is called for short tower machine, also claims tower crane, and its crane arm is contained in the rotary crane on towering tower body top.Working space is large, is mainly used in the installation of vertical and horizontal feed and the building element of material in housing construction.By metal construction, operating mechanism and electric system three parts, formed.Metal construction comprises tower body, crane arm and base etc.Operating mechanism hoists, luffing, revolution and walking four parts, and crawler body mainly comprises cocked trailer.Electric system comprises electrical motor, controller, electric power distribution cabinet, connection line, signal and illumination equipment etc.
In recent years, three layers and with storied building, residential building, in the small building constructions such as low layer industrial building, adopts universal building tower crane more, install, transportation and conversion building site inconvenient, construction cost is high, operating efficiency is lower.Particularly when new countryside construction is constructed, the restriction that is subject to transporting road conditions and conversion building site is more, and common way is that universal building tower crane is divided into a plurality of parts, then, being transported to respectively job location, in job location, is installing on the spot.But this universal building tower crane field-mounted process time and effort consuming, and there is potential safety hazard; In transportation, need to could realize the transfer in place by other transportation devices, increased traffic cost simultaneously.
The transportation of Mini-tower hoist tool at present is mainly realized by cocked trailer, but cocked trailer need to be placed at hinge-point opposite side the clump weight of constant weight in cocked tower body process, clump weight has increased cost as the accessory of complete machine, and clump weight weight is large, and transportation is inconvenient.
Summary of the invention
Goal of the invention: the purpose of this utility model be to provide a kind of in installation process during cocked tower body without the cocked trailer that the Mini-tower hoist tool of clump weight is set.
Technical scheme: a kind of cocked trailer of Mini-tower hoist tool, comprise trailer skeleton, steering front wheel, driven trailing wheel, cocked cylinder installation position and tower body hinge-point, described tower body hinge-point is positioned at trailer skeleton rear, described cocked cylinder installation position is positioned at the below at trailer skeleton middle part, described trailer skeleton rear expenditure pair of parallel is in the supporting component of trailer skeleton, described supporting component comprises bracing frame and the strong point, and the described strong point is positioned at the rear of tower body hinge-point.When the cocked tower body of needs, cocked cylinder two ends are connected with tower body with the cocked cylinder installation position on trailer skeleton respectively, the piston rod of cocked cylinder stretches out, tower body rotates around the tower body hinge-point at trailer skeleton rear, when center of gravity turns over driven trailing wheel because trailer skeleton rear is provided with pair of parallel in the supporting component of trailer skeleton, the strong point of described supporting component is positioned at the rear of tower body hinge-point, and therefore whole equipment can not produce potential safety hazard because of crank generation hypsokinesis.
Preference, in order to facilitate the transportation of complete machine, the described strong point comprises the first strut bar and the second strut bar, and described the first strut bar and the second strut bar are hinged with bracing frame end respectively, and described the first strut bar side relative to the second strut bar is respectively equipped with the portion of being connected and fixed.When trailer is during in travelling position, the first strut bar rearward overturns vertical with trailer skeleton fixing, and the second strut bar overturns forward parallel with trailer skeleton fixing; When the cocked tower body of needs, the first strut bar and the second strut bar are drawn close mutually, by the portion of being connected and fixed, realize being fixedly connected with each other.
Preference, in order to facilitate equipment to carry out movement by a small margin after installation, described the first strut bar and the second strut bar end are respectively equipped with roller.
Preference, in order to solve the problem that cornering resistance is large, described steering front wheel comprises front wheel body, turns to support roller and turns to supporting disk, describedly turn to the midway location that supporting disk is positioned at front wheel body and be fixedly connected with front wheel body, the described support roller that turns to is fixedly connected with trailer skeleton front end, described in turn to support roller to rotate turning on supporting disk.
Beneficial effect: the utility model compact conformation, space connection and reasonable arrangement, floor area is little, flexible operation; The disposable cocked installation of the major part that can complete fast tower body and carry, disposable dismounting keeps flat and proceeds to transportation operating mode; And can carry part tower machine accessory device transition transportation; Work capacity when having greatly reduced installation, the dismounting of this tower machine and having transported, makes this tower machine under restricted workyard and transportation road conditions, has higher work efficiency, has greatly reduced the demand to extra auxiliary installing device.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As illustrated in fig. 1 and 2, a kind of cocked trailer of Mini-tower hoist tool, comprise trailer skeleton 1, steering front wheel 2, driven trailing wheel 3, cocked cylinder installation position 4 and tower body hinge-point 5, described tower body hinge-point 5 is positioned at trailer skeleton 1 rear, described cocked cylinder installation position 4 is positioned at the below at trailer skeleton 1 middle part, described trailer skeleton 1 rear expenditure pair of parallel is in the supporting component 6 of trailer skeleton 1, described supporting component 6 comprises bracing frame 61 and the strong point 62, and the described strong point 62 is positioned at the rear of tower body hinge-point 5.When the cocked tower body of needs, cocked cylinder two ends are connected with tower body with the cocked cylinder installation position 4 on trailer skeleton 1 respectively, the piston rod of cocked cylinder stretches out, tower body rotates around the tower body hinge-point 5 at trailer skeleton 1 rear, when center of gravity turns over driven trailing wheel 3 because trailer skeleton 1 rear is provided with pair of parallel in the supporting component 6 of trailer skeleton 1, the strong point 62 of described supporting component 6 is positioned at the rear of tower body hinge-point 5, and therefore whole equipment can not produce potential safety hazard because of crank generation hypsokinesis.
