Abstract
The invention discloses a kind of gantry crane trolley walking mechanism automatic anchoring device thereofs, its main feature is that the device is made of anchor block and positioning pin, electric pushrod, driving lever and first, second limit switch, it is on the mounting bracket being fixedly connected that the bolt, electric pushrod, the first and second limit switches, which are arranged on trolley,；The anchor block and driving lever are arranged on main beam structure；The driving lever triggers trolley Reduced Speed Now after first limit switch, trolley is automatically in place after driving lever triggers the second limit switch, and start electric pushrod and positioning pin is inserted into anchor block, realize the automatic anchoring of trolley, it is on the contrary, start electric pushrod and extract positioning pin, release trolley anchoring.The present invention compared with prior art have it is simple in structure, have a safety feature, mitigate the live load of driver, preferably solve wheeling mechanism high-altitude anchoring safety problem, installation and it is easy to maintain.
Description
Technical field
The present invention relates to technical field of crane equipment, especially a kind of gantry crane trolley for windproof antiskid
Walking mechanism automatic anchoring device thereof.
Background technology
At present, it has all been pressed in crane operating mechanism《Safety rules for lifting appliances》Requirement, in orbit
The crane of outdoor work employs complete draught exclusion device.But for gantry crane, trolley is being arranged in girder knot
It is run on the track of structure, also all trolley is locked using the artificial anchored modes such as handle or insertion bolt of pulling at present, is increased
Maintenance personnel's labor intensity is added, while large-sized gantry crane complete machine is higher, particularly girder apical side height reaches or surpasses
80 meters are crossed, and wind-proof device is installed on wheeling mechanism, use environment is in the marginal position of structure, and personnel are manual
During operation, the danger of accidental falling is larger, and depending merely on driver can not the locking of complete independently trolley.
The anchoring device of the prior art need to manually pull handle or be inserted into bolt, and high-altitude manual operation is dangerous big, especially
Trolley lock when need to by related personnel's floor manager it is in place after, could complete be anchored operation, operation loaded down with trivial details, labor intensity
Greatly.
Invention content
A kind of gantry crane trolley walking mechanism designed the purpose of the present invention is being directed to prior art deficiency
Automatic anchoring device thereof, using limit switch and the anchoring structure of electronic plug positioning pin, realize the automatic in place of trolley and
Anchoring, anchoring operation is convenient, significantly reduces the live load of driver, and trolley is anchored safely, effectively, preferably solves
The safety problem of trolley high-altitude anchoring, it is simple in structure, it has a safety feature, manufacture is at low cost, installs and easy to maintain.
The object of the present invention is achieved like this：A kind of gantry crane trolley walking mechanism automatic anchoring device thereof,
Its main feature is that the automatic anchoring device thereof is opened by anchor block and positioning pin, electric pushrod, driving lever, the first limit switch and the second limiting
Composition is closed, the positioning pin, electric pushrod, the first limit switch and the second limit switch are arranged on to be connected with trolley to be fixed
On the mounting bracket connect；The anchor block and driving lever are arranged on the main beam structure of crane；The electric pushrod is with positioning pin
Axial connection；The control signal of first limit switch is connect with running gear for trolley；The control of second limit switch
Signal is connect respectively with electric pushrod and running gear for trolley；Trolley slows down after the driving lever triggers first limit switch
Traveling, trolley is automatic in place on anchor station after driving lever triggers the second limit switch, and start electric pushrod will be fixed
Position pin is inserted into the anchor hole of anchor block, realizes that trolley is anchored automatically on main beam structure, is extracted conversely, starting electric pushrod
Positioning pin releases trolley anchoring.
First limit switch and the second limit switch are respectively fixedly disposed at mounting bracket both sides, and with the length of driving lever
To be correspondingly arranged.
The present invention has the advantages that automatic in place and anchoring compared with prior art, significantly reduces the work of driver
Load preferably solves the safety problem of wheeling mechanism high-altitude anchoring, simple in structure, has a safety feature, manufactures cost
It is low, it installs and easy to maintain.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is Fig. 1 side views；
Fig. 3 is anchored schematic diagram for trolley.
Specific embodiment
Refering to 1~Fig. 2 of attached drawing, the present invention is by anchor block 2, positioning pin 3, electric pushrod 4, the first limit switch 5, driving lever 6
It is formed with the second limit switch 7, the positioning pin 3, electric pushrod 4, the first limit switch 5 and the second limit switch 7 are arranged on
It is on the mounting bracket 1 being fixedly connected with trolley 8；The anchor block 2 and driving lever 6 are arranged on the main beam structure 9 of crane；
The electric pushrod 4 is connect with positioning pin 3 to be axial；The control signal of first limit switch 5 connects with running gear for trolley
It connects；The control signal of second limit switch 7 is connect respectively with electric pushrod 4 and running gear for trolley；First limiting
5 and second limit switch 7 of switch is separately fixed at 1 both sides of mounting bracket, and with the length of driving lever 6 to be correspondingly arranged.
The present invention is installed and is used in this way：Anchor block 2 and driving lever 6 are fixed to the positioning of anchor of main beam structure 9
It puts, and the control signal of electric pushrod 4, the first limit switch 5 and the second limit switch 7 is respectively connected to trolley 8
Driver's cabin control device.
Refering to attached drawing 3a, when trolley 8 need to carry out parking anchoring, trolley 8 is moved close to anchor by driver
Positioning is put, and selects the anchoring operation of " anchoring manually " or " automatic anchoring " program progress trolley 8.
Refering to attached drawing 3b, when trolley 8 proceeds to driving lever 6, trigger trolley 8 after the first limit switch 5 slow down after
Continuous movement.
Refering to attached drawing 3c, trolley 8 is parked on anchor station, and send out small after driving lever 6 triggers the second limit switch 7
The signal that vehicle can be anchored in place starts electric pushrod 4 and positioning pin 3 is pushed to be inserted into the anchor hole of anchor block 2, when electric pushrod 4
When extending limit switch action, electric pushrod 4 stops, then completes the anchoring of trolley 8.Conversely, releasing anchoring only needs to start
Electric pushrod 4 extracts positioning pin 3 from the anchor hole of anchor block 2, when 4 retraction limit switch of electric pushrod acts, electric pushrod 4
Stop, that is, release the anchoring of trolley 8, trolley 8 can normal movement.
Above only the present invention is further illustrated, and not to limit this patent, all is equivalence enforcement of the present invention,
It is intended to be limited solely by within the right of this patent.
