Abstract
The utility model relates to a rotation prevention device for a climbing passageway of a tower crane. The rotation prevention device comprises a slewing support, a detection element mounting base, a detection element, turnover doors and a turnover door hinge; the detection element mounting base is arranged on the slewing support; the turnover doors are connected with each other through the turnover door hinge; and the detection element is arranged on the detection element mounting base and faces to the adjacent side of the connection of the turnover door hinge. According to the opening/closing of the turnover doors, a detection switch controls the on/off of a power supply of a slewing mechanism of the tower crane through a control system, therefore, the slewing mechanism of the tower crane can be prevented from being started; and the protection device, namely, the rotation prevention device, has the advantages that the safety and the reliability are good, the operation is convenient, the structure is compact, the cost is low, and the mounting and the maintenance are convenient.
Description
Technical field
The utility model is about being installed in the climb safety guard at passage turnover door place of top slewing tower crane.
Background technology
The top slewing tower crane is equipped with the passage that climbs that leads to driver's cab; And the passage that climbs need pass through the transition portion of fixed tower and last revolution support and connection place; When the staff through here the time, if the tower machine turns round, certainly will damage or panic the staff; Owing to be aloft work, cause safety misadventure to take place easily.The top slewing tower crane that uses does not in the market have this fender guard.In order to improve tower machine staff life safety; Anti-rotation device is installed at the passage turnover door place of climbing in that turning down is supported, and when guaranteeing that the staff supports through last revolution, tower machine swing type mechanism is in halted state; Conscientiously play the safety guard-safeguard effect, ensure safety through the staff of passage.This fender guard is through the power supply of detector switch control tower machine swing type mechanism, and when guaranteeing that turnover door is opened, the tower tester in power-down state is in off working state, prevents the staff is caused personal injury.
Summary of the invention
The utility model is exactly to above-mentioned shortcoming, and the mechanical and electrical protection device that a kind of safe and reliable, easy to operate, compact conformation, cost are low, be convenient to installation and maintenance is provided.
The technical scheme that the utility model adopted is: the tower machine passage anti-rotation device that climbs; Comprise pivoting support, detecting element mount pad, detecting element, turnover door, turnover door hinge; It is characterized in that: the detecting element mount pad is set on the described pivoting support; Turnover door is connecting with the turnover door hinge, and described detecting element is installed on the detecting element mount pad, and detecting element is facing to the adjacent side of turnover door hinge bonded assembly.
Described detector switch is according to the switching of turnover door, and the power supply through control system control tower machine swing type mechanism cut-offs, and can prevent the swing type mechanism startup work of tower machine.
Say that further when turnover door was opened, detecting element detected signal, break off tower machine swing type mechanism circuit, prevent the work of tower machine swing type mechanism, thereby the staff through turnover door is played the safety guard-safeguard effect through control system.
When turnover door was in normal closed condition, detecting element is not worked, and was inoperative to the mode of operation of tower machine swing type mechanism power supply.
The beneficial effect of the utility model is: such fender guard has the advantage that safe and reliable, easy to operate, compact conformation, cost are low, be convenient to installation and maintenance.
Description of drawings
Fig. 1 is the climb front view of passage anti-rotation device of tower machine.
Fig. 2 is the climb A-A section-drawing of passage anti-rotation device of Fig. 1 tower machine.
Fig. 3 is the tower machine turnover door of the passage anti-rotation device cutaway view when opening that climbs.
Fig. 4 is the climb partial view of passage anti-rotation device of tower machine.
Among the figure: 1, pivoting support; 2, detector switch mount pad; 3, detecting element; 4, turnover door; 5, turnover door hinge.
The specific embodiment:
Like Fig. 1,2,3, shown in 4; The tower machine passage anti-rotation device that climbs; Comprise pivoting support 1, detecting element mount pad 2, detecting element 3, turnover door 4, turnover door hinge 5, it is characterized in that: on the described pivoting support 1 detecting element mount pad 2 is set, turnover door 4 usefulness turnover door hinges 5 are connecting; Described detecting element 3 is installed on the detecting element mount pad 2, and detecting element 3 is facing to the adjacent side of turnover door hinge 5 bonded assemblys.
In the switching of described detecting element 3 according to turnover door 4, the power supply through control system control tower machine swing type mechanism cut-offs, and can prevent the swing type mechanism startup work of tower machine.
Say that further when turnover door 4 was opened, detecting element 3 detected signal, break off tower machine swing type mechanism circuit, prevent the work of tower machine swing type mechanism, thereby the staff through turnover door is played the safety guard-safeguard effect through control system.
When turnover door was in normal closed condition, detecting element is not worked, and was inoperative to the mode of operation of tower machine swing type mechanism power supply.
