Abstract

The utility model relates to a crane part, in particular to a crane cart traveling mechanism with a travel switch, which mainly solves the technical problems of complexity, high production cost, difficulty in assembly, erection and maintenance, incapability of automatically limiting the operation distance and the like of the crane cart traveling mechanism existing in the prior art. The crane cart traveling mechanism comprises an upper balance beam (1), wherein an upper bearing seat (2) is fixedly arranged on the upper balance beam. The crane cart traveling mechanism is characterized in that the two ends of the upper balance beam are fixed with a lower balance beam (4) through a lower bearing seat (3) respectively; the two ends of each lower balance beam are connected with a driving trolley (5) and a driven trolley (6) respectively; the driving trolley is provided with a motor (7) and a speed reducer; the lower part of the driven trolley is provided with the travel switch (9); and the travel switch is connected with a numerical control device through a circuit; and the numerical control device is connected with the motor.

Description

A kind of crane large vehicle walking mechanism of tape travel switch
Technical field
The utility model relates to a kind of hoisting crane parts, especially relates to a kind of crane large vehicle walking mechanism of tape travel switch.
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 cart walking mechanism of these hoisting cranes is comparatively complicated, and productive costs is higher, and assembling is built, keeps in repair also comparatively difficult, and range ability can not carry out automatic spacing.
The utility model content
The utility model provides a kind of crane large vehicle walking mechanism of tape travel switch; It mainly is that to solve the cart walking mechanism of existing in prior technology hoisting crane comparatively complicated; Productive costs is higher; Assembling is built, keeps in repair also comparatively difficult, and range ability can not carry out the technical matters of automatic spacing etc.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
The crane large vehicle walking mechanism of a kind of tape travel switch of the utility model comprises equalizing bar, is fixed with upper branching holder on the last equalizing bar; Described two ends of going up equalizing bar respectively are fixed with a following equalizing bar through the lower support seat; The two ends of every following equalizing bar are connected with initiatively chassis and passive chassis respectively, and initiatively chassis is provided with electrical motor and retarder, and the bottom of passive chassis is provided with travel switch; Travel switch connects numerical control device through circuit, and numerical control device connects electrical motor.
As preferably, the front end of described active chassis is connected with energy disperser, and clear rail plate lower end is stretched in the track.
As preferably, the front end of described active chassis is connected with rail plate clearly.
Therefore, the utility model is relatively simple for structure, and assembling, maintenance are all more or less freely, and productive costs is lower, through travel switch can the time hoisting crane run to auto-stop behind the certain distance.
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: the crane large vehicle walking mechanism of a kind of tape travel switch of this example; Like Fig. 1, comprise equalizing bar 1, be fixed with upper branching holder 2 on the last equalizing bar; The two ends of last equalizing bar respectively are fixed with a following equalizing bar 4 through lower support seat 3; The two ends of every following equalizing bar are connected with initiatively chassis 5 and passive chassis 6 respectively, and initiatively chassis is provided with electrical motor 7 and retarder, and the bottom of passive chassis is provided with travel switch 9; Travel switch connects numerical control device through circuit, and numerical control device connects electrical motor.Initiatively the front end of chassis is connected with energy disperser 8, and clear rail plate lower end is stretched in the track.Initiatively the front end of chassis is connected with rail plate 10 clearly.
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 (3)

1. the crane large vehicle walking mechanism of a tape travel switch; Comprise equalizing bar (1); Be fixed with upper branching holder (2) on the last equalizing bar, it is characterized in that described two ends of going up equalizing bar respectively are fixed with a following equalizing bar (4) through lower support seat (3), the two ends of every following equalizing bar are connected with initiatively chassis (5) and passive chassis (6) respectively; Initiatively chassis is provided with electrical motor (7) and retarder; The bottom of passive chassis is provided with travel switch (9), and travel switch connects numerical control device through circuit, and numerical control device connects electrical motor.
