Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

The first embodiment is as shown in fig. 1, and the tower crane anti-climbing device comprises a fence unit 1 arranged around a tower crane A, a safety door 2 arranged on the fence unit 1 and used for people to enter the tower crane A, and a baffle unit 3 arranged on the top surface of the fence unit 1 and used for blocking climbing. Overlook visual angle in fig. 2 and see, fence unit 1 is equipped with a plurality of to a rectangle in the wall, this rectangle and tower crane A interval certain distance are about 1m, and this distance makes anti-climb device can not occupy too much land area, and can prevent effectively that the climber from separating fence unit 1 and directly seizing the tower crane climbing. Emergency exit 2 sets up on arbitrary one fence unit 1, and this fence unit 1 is emergency exit 2 and is equipped with the installation frame in advance, and emergency exit 2 installs on this installation frame and is equipped with the safety lock, and the key is kept in tower crane staff's hand, and it can to open emergency exit 2 when needing to use the tower crane and get into, convenient operation. The baffle unit 3 sets up on fence unit 1 upper strata, and is different from fence unit 1, and baffle unit 3 is solid construction, and baffle unit 3's setting makes the people that respectively just hand was strong climb to the top layer of fence unit 1 even only by holding the railing on fence unit 1, also can't obtain the point of effective gripping through baffle unit 3 to the climbing fails. Certainly, if the fence unit 1 is also set to be a solid structure, irrelevant personnel cannot climb, but the fence unit 1 is made of multiple materials due to the design, and the dismounting and the transportation are difficult, so that the inventor finds that the fence unit 1 and the baffle unit 3 are the most scientific after multiple designs, not only has the characteristics of convenience and easiness in dismounting, but also obtains the same effect as a fence with a full solid structure.

The detailed design of the barrier unit 1 plus the baffle unit 3 will be explained one by one hereinafter.

< regarding the fence unit 1>

The barrier unit 1 includes a frame 101, and vertical reinforcing posts 102 provided on the frame 101. Vertical reinforcement post 102 perpendicular to ground design for it is difficult to climb upwards with the help of helping hand when non-tower crane staff tries to climb, but only sets up vertical reinforcement post 102, in some use scenarios, because the steel pipe or the reinforcing bar of preparation vertical reinforcement post 102 have certain plasticity, non-tower crane staff can directly get into through bending off vertical reinforcement post 102, so still need transversely set up a horizontal reinforcement post 103, prevent to be bent off with the fingers and thumb for fixed each vertical reinforcement post 102. However, after the transverse reinforcing columns 103 are arranged, the potential for assisting a worker not on a tower crane to climb is existed, and based on the potential, the distance between the vertical reinforcing columns 102 is 240-200mm in the embodiment, because the width of the foot of a general adult is 250-210mm, and according to statistics, people climbing the tower crane illegally, with more men, the distance between the vertical reinforcing columns 102 is set to be narrower than the width of one sole of the general adult, so that the general people cannot insert the foot and use the transverse reinforcing columns 103 to help.

In addition, in order to avoid the foot width of an individual being less than 200mm, in the embodiment, the distance between two transverse reinforcing columns 103 is limited to be too low, so that even if one foot of the climber uses the transverse reinforcing column 103 for borrowing force, the other foot of the climber hardly contacts the previous transverse reinforcing column 103, and through tests, when the vertical distance of the transverse reinforcing columns 103 is more than 1000mm, the climber is almost impossible to use the two transverse reinforcing columns 103 for borrowing force at the same time, but the distance between the transverse reinforcing columns 103 cannot be too large, otherwise, insufficient supporting force for the vertical reinforcing columns 102 is caused, and the distance between the transverse reinforcing columns 103 is optimally kept to be less than 2000mm.

< regarding the shutter unit 3>

Some scramblers only utilize two vertical reinforcement post 102 on the left and right sides can accomplish the climbing, in order to prevent this type of scrambler, in this embodiment, the frame 101 top still is equipped with baffle 301 in addition, even 2 vertical reinforcement posts 102 climb to frame 101 top like this, do not have any part that can snatch to reach tower crane A yet, through the test, when baffle 301 vertical height is greater than 1500mm, the climber just can not grasp frame 101 top by one hand, another hand contacts baffle 301 top gravity-assist simultaneously, and for the convenience dismouting transportation, baffle 301 vertical height designs and is not greater than 2000mm.

Some scramblers probably carry the instrument climbing, for example, the ladder, the above measure of preventing from climbing will lose the effect like this, for this reason, in this embodiment, apron 302 has been set up at baffle 301 top, even make the scrambler climb to baffle 301 topmost, also can not cross baffle 301 and enter into tower crane A base department (tower crane A and apron 302 between sealed the setting make the unable direct entering of climber), in addition, can set up the spine around apron 302 and prevent the climber and borrow the power, this kind of spine can not cause the injury to the people, but can block the power of borrowing process of people to the apron, thereby make it unable hard to grasp because of the conditioned reflex of the sense of pain.

In addition, the terms "vertical", "horizontal", "top", "bottom", "front", "back", "upper", "lower", "inner", "outer", and the like in the embodiments of the present invention refer to the orientation or positional relationship based on the drawings, or the orientation or positional relationship that the product is conventionally placed when in use, only for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
