Abstract
The invention relates to a rail clamping device special for a wind load-resisting and overturn-preventing crane, comprising a box body, a hand wheel device and a nut in threaded connection with the lower part of a rotating shaft of the hand wheel device, wherein the nut is connected with a connecting rod mechanism, and a clamping block is connected to a connecting rod of the connecting rod mechanism. The clamping rail device is characterized in that an overturn-preventing bending part which is connected with the connecting rod into a whole is arranged at the lower end part of the connecting rod of the connecting rod mechanism. The invention has the advantages that: when the crane is in a non-work state, the hand wheel device is rotated to drive the connecting rod mechanism and the clamping block to act, thus the clamping block can be used for clamping a crane rail; and when wind blows or wind force is over-strong and the crane rail is clamped by using the clamping block, the overturn-preventing bending part at the lower end part of the connecting rod can be also used for hooking a rail head part of the crane rail, so that a gantry crane can be prevented from automatically sliding, going off the rail and generating overturn accidents due to the wind force and other outside factors and the safety of field operators and the crane under the non-work conditions is ensured.
Description
Technical field
The invention belongs to the handling machinery technical field, particularly relate to a kind of wind resistance and carry 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; 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 present invention 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 present invention takes 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, the rotating shaft lower thread coupling nut of described handwheel devices, on nut, connect connecting rod mechanism, be connected with the clamp that is used to step up crane track on the connecting rod of described connecting rod mechanism, it is characterized in that: the connecting rod bottom of described connecting rod mechanism is shaped on the anti-tipping dogleg section that is connected as a single entity with it.
The present invention can also adopt following technical scheme:
The bending curve of the anti-tipping dogleg section of described connecting rod bottom and rail head lower surface shape match.
Advantage and good effect that the present invention has are: because the present invention 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 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 be subjected to 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 a structural representation of the present invention;
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 of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail 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 described 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 by bearing pin, and described connecting rod mechanism is to be made of short connecting rod 3-1 and the long connecting rod 3-2 that is movably hinged with it, is connected with the clamp 4 that is used to step up crane track 6 on long connecting rod.The long connecting rod bottom of described 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 described 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.
Principle of work of the present invention 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 be subjected to 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 present invention can improve on the basis of existing crane rail clamp, can use.
