Abstract
The anti-climbing safety device of a kind of tower crane that the utility model relates to building ground use passes through door status switch (4) and skeleton (8) by access door (6) one end, and the other end is connected with skeleton (8) by hinge (7).When tower lifting people operator will pass through operational tower machine on access door (6) to tower crane, need to open door status switch (4) with special magnetic card (9), promote access door (6), after access door (6), access door (6) under gravity, the door status switch (4) of access door (6) automatically on skeleton (8), access door (6) is held by magnetic force by door status switch (4) tightly, if at this moment non-tower crane operator climbs upper tower crane not having the situation of magnetic card (9) to have no idea to push access door open, use very convenient, safe and reliable, can effectively prevent NOT operation personnel from climbing tower crane.
Description
Technical field:
The utility model relates to construction machine safety protection field, particularly the anti-climbing safety device of tower crane that uses of a kind of building ground.
Background technology:
Current China construction site tower crane exists in a large number, and existing general workman on-site but not the event that the special operation workers relevant to tower crane climbing tower crane malice is asked for salary often occur, and cause very severe social influence.Sometimes because climbing personnel psychology and physiological reason also can crash into ground from tower crane and cause casualty accident.This event can only after occurring in the past, and arrange personnel's persuasion and education, promise their some unreasonable demands or please rescue by Fire soldier, often effect is undesirable for this, does not have a kind of effective ways of pre-control in advance, can not tackle the problem at its root.
Summary of the invention:
Technical problem to be solved in the utility model is exactly climb the generation of event and industrial accident in order to avoid non-tower crane operator and provide a kind of tower crane anti-climbing safety device, this tower crane anti-climbing safety device cost of manufacture is low, simple to operate, easy to use and reliable, can fundamentally prevent from, with the generation avoiding a little class event, being applicable to all kinds of tower crane.
The technical solution adopted in the utility model is:
The anti-climbing safety device of a kind of tower crane, be made up of checkered steel plate, door status switch, bolt, hinge, skeleton, access door, magnetic card, be provided with access door one end and the chain connection of door status switch, the access door other end is connected with skeleton by door status switch, hinge is connected with skeleton, skeleton is connected with diamond plate, and skeleton is connected with skeleton.
Described access door is provided with door status switch.
It is that electromagnetic force by door status switch connects that described access door one end is connected with skeleton.
Described access door and the skeleton other end are that hinge type connects.
Described checkered steel plate is welded on skeleton.
Described skeleton and skeleton are bolted between this.
The utility model can prevent non-tower crane operator from climbing tower crane, has and manufactures and use simple, convenience, safety, reliability high.Even more important is effectively to prevent non-tower crane operation from climbing tower crane, and the probability causing ground high falling industrial accident generation because of climbing tower crane can be close to zero.
Accompanying drawing illustrates:
Fig. 1 is that the anti-climbing safety device of tower crane looks schematic diagram.
Fig. 2 is that schematic diagram is looked in the anti-climbing safety device access door unlatching of tower crane.
Fig. 3 is that the anti-climbing safety device skeleton of tower crane looks schematic diagram.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1 and Figure 2, the anti-climbing safety device of this tower crane, access door 6 is provided with door status switch 4, access door 6 one end is connected with skeleton 8 by door status switch, access door 6 other end is connected with skeleton by hinge 7 with skeleton, and skeleton 8 is connected by bolt 5 with skeleton 8, skeleton 8 welds checkered steel plate 1, skeleton 8 is placed on horizon bar 3, and tower owner chord member 2 and horizon bar 3 are welded to connect.
Concrete operations are as follows: when tower lifting people operator will pass through operational tower machine on access door 6 to tower crane, need to open door status switch 4 with special magnetic card 9, promote access door 6, after access door 6, access door 6 under gravity, the door status switch 4 of access door 6 automatically on skeleton 8, access door 6 is held by magnetic force by door status switch 4 tightly, if at this moment non-tower crane operator climbs tower crane not having the situation of magnetic card to have no idea to push access door open.
It should be noted that: skeleton 8 be by bolt 5 be spliced into one overall time, need to be tilted through tower owner chord member 2.Hinge 7 is installed in 8 four, skeleton choosing wherein two adjacent skeletons 8.
