Abstract
The utility model relates to a clamping rail device special for an anti-wind-load and overturn-preventing crane, which comprises a box body, a hand wheel device and a nut in threaded connection to the lower portion of a rotating shaft of the hand wheel device. A connecting rod mechanism is connected to the nut, and a clamping block is connected to the connecting rod of the connecting rod mechanism. The clamping rail device special for the anti-wind-load and overturn-preventing crane is characterized in that an overturn-preventing bending portion integrated with the connecting rod is arranged at the lower end of the connecting rod of the connecting rod mechanism and has the advantages that when the crane is in a non-working state, users can rotate the hand wheel device to lead the connecting rod device and the clamping block to move, and the clamping block can clamp a crane rail tightly. When wind rises or the wind force is excessive and the crane rail is clamped through the clamping block, the overturn-preventing bending portion at the lower end of the connecting rod can further hook the rail head position of the crane rail, thereby preventing a gantry crane from automatically sliding and deorbiting from the rail and avoiding overturn accidents and guaranteeing the safety of operation personal on the site and the crane under a non-working condition.
Description
Technical field
The utility model belongs to the handling machinery technical field, particularly relates to a kind of wind resistance and carries the special-purpose rail clamping device of the anti-hoisting crane that topples.
Background technology
Hoisting crane is widely used in fields such as nuclear power, military project, metallurgy, machinery, chemical industry, petroleum-based energy, and wherein, gauntry crane is widely used in outdoor work; In process of production, after gauntry crane stops, because environmental factor; It is the effect of wind load; Through regular meeting the accident that hoisting crane is arrived by wind taking place, so not only to hoisting crane self, and all there is very big potential safety hazard in operating personal.In order to address the above problem, traditional gauntry crane all is equipped with crane rail clamp, and its structure is mainly by handwheel devices, casing, connecting rod mechanism with step up device and form.Its principle of work is: casing and crane end carriage bolted connection, and when gauntry crane was in off working state, operating personal rotated handwheel devices, and drivening rod mechanism and fixing device action clamp crane track.When blowing, rely on fixing device to clamp crane track, prevent hoisting crane because wind effect slides voluntarily.But above-mentioned rail clamping device only can prevent the crane track derailing, and can't avoid hoisting crane in the production scene overthrow accident to take place because structure is limit.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, can prevent to de-orbit after hoisting crane from stopping and the wind resistance of overthrow accident carries the special-purpose rail clamping device of the anti-hoisting crane that topples.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Wind resistance carries the special-purpose rail clamping device of the anti-hoisting crane that topples; Comprise casing; Handwheel devices is installed on casing, and the rotating shaft lower thread coupling nut of said handwheel devices connects connecting rod mechanism on nut; Be connected with the clamp that is used to step up crane track on the connecting rod of said connecting rod mechanism, it is characterized in that: the connecting rod bottom of said connecting rod mechanism is shaped on the anti-tipping dogleg section that is connected as a single entity with it.
The utility model can also adopt following technical scheme:
The bending curve of the anti-tipping dogleg section of said connecting rod bottom and rail head lower surface shape match.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; When hoisting crane is in off working state; Operating personal rotates handwheel devices; Descending and the drivening rod device of the nut of handwheel devices, the long connecting rod of linkage drive the clamp action, and clamp can clamp crane track.When blowing or wind-force when excessive; When relying on clamp to clamp crane track; The anti-tipping dogleg section of connecting rod bottom also can be hooked the rail head part of crane track; Can prevent like this gauntry crane receive external factor such as wind-force from line slip, deviate from track and capsizing case take place, guarantee the safety under site operation personnel and the hoisting crane inoperative condition.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, handwheel devices; 1-1, handwheel; 1-2, rotating shaft; 1-3, nut; 2, casing; 3, connecting rod mechanism; 3-1, short connecting rod; 3-2, long connecting rod; 4, clamp; 5, anti-tipping dogleg section; 6, track.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, wind resistance carries the special-purpose rail clamping device of the anti-hoisting crane that topples, and comprises casing 2, and handwheel devices 1 is installed on casing 2.On the handwheel 1-1 of said handwheel devices rotating shaft 1-2 is housed, is shaped on screw thread in the bottom of rotating shaft 1-2, the rotating shaft lower thread is connected with nut 1-3.Connecting rod mechanism 3 is connected with the nut of handwheel devices through bearing pin, and said connecting rod mechanism is to be made up of short connecting rod 3-1 and the long connecting rod 3-2 that is movably hinged with it, on long connecting rod, is connected with the clamp 4 that is used to step up crane track 6.The long connecting rod bottom of said connecting rod mechanism also is shaped on the anti-tipping dogleg section 5 that is connected as a single entity with it, and the rail head lower surface shape of the bending curve of the anti-tipping dogleg section of said connecting rod bottom and track 6 matches.In normal operation, be provided with the gap of 5-10mm between anti-tipping dogleg section 5 and the track.
The principle of work of the utility model is:
With the end carriage bolted connection of casing 2 with hoisting crane; When hoisting crane was in off working state, operating personal rotated handwheel devices, the descending and drivening rod device of the nut of handwheel devices; The long connecting rod of linkage drives the clamp action, and clamp can clamp crane track.When blowing or wind-force when excessive; When relying on clamp to clamp crane track; The anti-tipping dogleg section of connecting rod bottom also can be hooked the rail head part of crane track; Can prevent like this gauntry crane receive external factor such as wind-force from line slip, deviate from track and capsizing case take place, guarantee hoisting crane and site operation personnel's safety.The utility model can improve on the basis of existing crane rail clamp, can use.
