Abstract
The utility model relates to an overload alarm device of a crane, for facilitating improvement of the safety of a lifting operation of the crane. A crane operator cannot easily learn the weight of a heavy object to be hoisted conveniently, accurately and effectively under normal conditions; the condition that a wire rope of the crane is snapped frequently appears. Thus, the overload alarm device of the crane is characterized by comprising a sleeve, a baffle block, a connecting rod, a pressure sensor and an electronic control unit, wherein a slideway is arranged inside the sleeve; the connecting rod sequentially comprises a slender rod, a connecting section and a thick rod from top to bottom; the diameters of the connecting section, the slender rod and the thick rod are sequentially increased; the baffle block is fixed inside the slideway of the sleeve, and arranged at the lower end of the sleeve; the shape and the size of the slender rod in the connecting rod are matched with those of the slideway in the sleeve; the slender rod is sleeved inside the slideway; the pressure sensor is arranged between the slender rod and the baffle block; the electronic control unit is electrically connected with the pressure sensor. The overload alarm device is simple in structure, reasonable in design, and convenient to use; improvement of the safety performance of the crane in the lifting operation is facilitated.
Description
Technical field
The utility model relates to a kind of overload alarm, especially relate to a kind of crane overload alarm, be mainly used in crane, when the weight of the object that will lift by crane when crane surpasses the gravity that crane can carry, crane overload alarm will send warning, is conducive to improve the safety of crane lifting operation.
Background technology
The Main Function of crane is hoisting heavy, generally, crane operation personnel are difficult to conveniently, accurate and actv. is known the weight of the weight that will lift by crane, and the pulling force that can bear of crane rope, general is all that experience by crane operation personnel self judges the weight of the weight that will lift by crane and pulling force that crane rope can bear, when the crane lifted weight exceeds the weight that crane rope can carry, the situation that often there will be crane rope to be pulled off, not only can break hung object, and even can cause casualties serious the time, safety is poor.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of simple in structure, and reasonable in design, easy to use, cost is lower, is convenient to promote the crane overload alarm that is conducive to improve safety performance in the crane lifting operation.
The technical scheme in the invention for solving the above technical problem is: the constructional feature of this crane overload alarm is: comprise sleeve pipe, block, connecting rod, pressure sensor and electronic control unit, be provided with slideway in described sleeve pipe, described connecting rod comprises thin bar from top to bottom successively, linkage section and thick bar, described linkage section, the diameter of thin bar and thick bar increases successively, described block is fixed in the slideway of sleeve pipe, this block is positioned at the lower end of sleeve pipe, in described connecting rod the shape of thin bar and size all with sleeve pipe in slideway mate, this thin bar is sleeved in slideway, described pressure sensor is arranged between thin bar and block, described electronic control unit and pressure sensor are electrically connected to.
As preferably, electronic control unit described in the utility model is fixed on the outer wall of sleeve pipe.
As preferably, connecting rod described in the utility model is the integral type structure.
As preferably, sleeve pipe described in the utility model and block are the integral type structure.
The utility model compared with prior art, have the following advantages and effect: between the weight hook and steel rope that are connected to crane, the utility model can will need by pressure sensor the weight data of lifting to convey to the crane operation personnel effectively, make the crane operation personnel to facilitate, accurate and the real-time weight of knowing the weight that will lift by crane, effectively prevent that the situation of overload from appearring in crane, thereby prevent the situation that crane rope is pulled off, guaranteed the stable rising of weight, and prevent personal casualty, safety while greatly having improved crane operation.Of the present utility model simple in structure, be convenient to manufacture, easy to use, cost is lower, is convenient to promote.
The accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of crane overload alarm in the utility model embodiment.
Fig. 2 is the sectional structure schematic diagram of connecting rod in the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 2, the crane overload alarm in the present embodiment comprises sleeve pipe 1, block 3, connecting rod 4, pressure sensor 5 and electronic control unit 6, and wherein, connecting rod 4 is the integral type structure.
Be provided with slideway 11 in sleeve pipe 1 in the present embodiment, connecting rod 4 comprises thin bar 41, linkage section 43 and thick bar 42 from top to bottom successively, and the diameter of linkage section 43, thin bar 41 and thick bar 42 increases successively, because thin bar 41 is thicker than linkage section 43, make thin bar 41 compare with linkage section 43, formed projection 2 in the outer ring of thin bar 41.
In the present embodiment connecting rod 4 shape of thin bar 41 and size all with sleeve pipe 1 in shape and big or small coupling of slideway 11, this thin bar 41 is sleeved in slideway 11, linkage section 43 is just in time between block 3, and thin bar 41 can be slided in slideway 11, and the projection 2 on thin bar 41 can withstand on block 3.
The lower end of the slideway 11 of the present embodiment in sleeve pipe 1 is provided with block 3, thin bar 41 in connecting rod 4 is set in the slideway 11 of sleeve pipe 1, there is being projection 2 lower end of thin bar 41 near block 3 places, pressure sensor 5 is clamped between projection 2 and block 3, crane overload alarm in the present embodiment in use, when crane need to be sling weight, crane overload alarm in the present embodiment is connected between the weight hook and steel rope of crane, thereby can know the gravity carried between crane weight hook and steel rope by pressure sensor 5, then can by electronic control unit 6, the weight data of knowing be conveyed to the crane operation personnel by actv., make the crane operation personnel to facilitate, accurate and the real-time weight of knowing the weight that will lift by crane, thereby prevent the situation that crane rope is pulled off, guaranteed the stable rising of weight in crane lifting process, and prevent personal casualty, improved the safety in crane lifting process.
In addition, it should be noted that, the specific embodiment described in this specification sheets, the shape of its parts and components, institute's title of being named etc. can be different, and the above content described in this specification sheets is only to the explanation of the utility model structure example.Allly according to the utility model patent, conceive equivalence variation or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
