Abstract
The utility model relates to components and parts of cranes, in particular to a lower trolley device for a crane, and the lower trolley device for the crane is mainly used for solving the technical problems of relatively-complicated structure, poor strength, higher production cost, incapability of safe distance determining during hoisting, difficulty in assembly and maintenance, and the like of the lower trolley device for the crane in the prior art. The lower trolley device comprises a trolley frame (1) and is characterized in that a lower trolley equipment room (2) is arranged on the trolley frame (1), roller wheels (3) are arranged at the bottom of the trolley frame, a primary hoisting mechanism (4) and a secondary hoisting mechanism (5) are arranged in the lower trolley equipment room, and a safety ruler (6) is arranged at the middle part of the trolley frame.
Description
Technical field
The utility model relates to a kind of hoisting crane parts, especially relates to carriage device under a kind of hoisting crane.
Background technology
Weight-lifting equipment is divided into transfer crane, crane in bridge type, beam crane and boom crane by device structure; Wherein transfer crane mainly representative equipment be gauntry crane; Crane in bridge type mainly representative equipment is the bridge formation machine, and boom crane mainly representative equipment is a tower crane.Transfer crane is mainly used in work operations such as the up-down, parallel motion of building ground, factory floor and shipyard harbour weight.Transfer crane mainly is made up of lifting overhead traveling crane, girder, supporting leg, traveling gear and electric hydraulic system.Its principle of work is: utilize the lifting overhead traveling crane that is installed on the girder that weight is raised up; The supporting leg upper end connects girder; The lower end connects with traveling gear, through being installed in the driving of motor on the traveling gear, realizes the effect that hoisting crane moves on rail; The overhead traveling crane of lifting simultaneously also can be walked on girder, realizes at last weight is hung the effect that moves on to another place from a place.But the structure of these monkey devices is comparatively complicated, and intensity is relatively poor, and productive costs is higher, can't confirm safety distance during lifting, assembles, maintenance is also comparatively difficult.
The utility model content
The utility model provides carriage device under a kind of hoisting crane; It mainly is that to solve the structure of existing in prior technology monkey device comparatively complicated, and intensity is relatively poor, and productive costs is higher; Can't confirm safety distance during lifting, the technical matters that assembling, maintenance also comparatively are difficult for etc.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
Carriage device under a kind of hoisting crane of the utility model comprises vehicle frame, and described vehicle frame is provided with down the dolly machine room, and bottom of frame is provided with roller, is provided with main hoisting mechanism and auxiliary hoisting mechanism in the following dolly machine room, and the middle part of vehicle frame is provided with safe chi.
As preferably, described vehicle frame two ends all are provided with energy disperser.
Therefore, the utility model is relatively simple for structure, and intensity is stronger, utilizes safe chi can measure safety distance, and is safer, and the assembling, the maintenance all more or less freely, productive costs is lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: carriage device under a kind of hoisting crane of this example, like Fig. 1, comprise vehicle frame 1, vehicle frame is provided with down dolly machine room 2, and bottom of frame is provided with roller 3, is provided with main hoisting mechanism 4 and auxiliary hoisting mechanism 5 in the following dolly machine room, and the middle part of vehicle frame is provided with safe chi 6.The vehicle frame two ends all are provided with energy disperser 7.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
Claims (2)
1. carriage device under the hoisting crane; Comprise vehicle frame (1), it is characterized in that described vehicle frame (1) is provided with down dolly machine room (2), bottom of frame is provided with roller (3); Be provided with main hoisting mechanism (4) and auxiliary hoisting mechanism (5) in the following dolly machine room, the middle part of vehicle frame is provided with safe chi (6).
2. carriage device under a kind of hoisting crane according to claim 1 is characterized in that described vehicle frame (1) two ends all are provided with energy disperser (7).
