Description
Technical field
The utility model relates to building construction hoist, is specifically related to a kind of building construction hoist limit for tonnage safety device.
Background technology
In the existing various building construction hoist; as towed building hoist; winding type building hoist etc.; its steel rope is terminal to be fastenedly connected with the box top; in work progress; when overloading, can cause box steel rope and cylinder to skid; braking failure; even steel rope tear fracture; box falls; serious safety misadventure takes place; generation for fear of accident; people install the overload protection device at elevator; it is 03226342.2 Chinese patent as the patent No.; the overload protection utensil of this patent has the control accuracy height; be active in one's movements; characteristics such as compact conformation and cost are low; but because the structural particularity of transmission building hoist itself; can't use the overload protection device of putting down in writing as above-mentioned patent; in order to guarantee construction safety; normally by limiting the load volume of elevator box; and the measures such as safety factor that increase power and running part; though this safety measure plays a positive role in actual applications; but its safety rate that reaches still is in fuzzy state, can only rely on experience in actual use or even feel and carry out operation, and potential safety hazard is very big.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of safe, reliable and stable building construction hoist limit for tonnage safety device is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of building construction hoist limit for tonnage safety device described in the utility model, comprise safety control, elevator switch box, weight sensor, described weight sensor is placed in below the elevator support board, safety control is electrically connected elevator switch box and weight sensor, and described safety control is provided with annunciator and telltale.
Further, described safety control also comprises amplifying unit, filter unit, A/D converting unit and microcomputer, and annunciator, telltale, amplifying unit are connected with microcomputer through filter unit, A/D converting unit.
Further, described annunciator comprises LED lamp and buzzer phone.
After adopting said structure, the utility model beneficial effect is: dependable performance is stable, easy for installation, debugging simply, anti-adverse environment, antijamming capability be strong, improved the safety of building ground.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of building construction hoist limit for tonnage safety device described in the utility model, comprise safety control 1, elevator switch box 3, weight sensor 2, described weight sensor 2 is placed in below the elevator support board 4, safety control 1 is electrically connected elevator switch box 3 and weight sensor 2, described safety control is provided with annunciator 5 and telltale 6, described safety control 1 also comprises amplifying unit, filter unit, A/D converting unit and microcomputer, annunciator 5, telltale 6, amplifying unit is through filter unit, the A/D converting unit is connected with microcomputer, and described annunciator comprises LED lamp and buzzer phone.
The utility model support board 4 is equipped with the power sensor 2 of weighing, safety control calculates the load-carrying of elevator according to pressure signal, as after the rated weight that overloaded, the power supply that sends in the signal control switch box disconnects, elevator stops work, simultaneously carry out sound and light alarm by LED siren horn and buzzer phone, and show current weight by telltale.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
