Abstract
The utility model relates to a tower concrete cloth pole for concrete cloth. The device mainly comprises a tower (28), a folding arm type distributing rod, a hoisting winch (3) and the like. The cargo hook assembly (19) is retracted into the hook clamping seat (18), the fixing pin (17) is inserted, concrete distribution operation can be conducted, or the tower body standard knot (27) is lifted by the tower body standard knot hook (25), the fixing pin (17) is pulled out, the cargo hook assembly (19) is put down, and other cargos can be lifted. Therefore, the utility model has the characteristics of simple structure, convenient conversion and multiple purposes.
Description
The utility model relates to the folding-jib boom, comprises hoisting winding, body of the tower standard knot suspension hook and goods suspension hook assembly, is applied to the realm of building construction.
The tower concrete placing boom that uses all has only the cloth simple function at present.During the boom jacking, need the crane gear lifting body of the tower standard knot by other, machinery expenses shared when therefore constructing is higher.In addition, boom is when non-cloth operating mode, and boom is had to leave unused, and can not bring into play other effect.
The purpose of this utility model provide a kind of can cloth, can lift by crane body of the tower standard knot, jacking boom again and lift by crane other goods, tower concrete placing boom that can a tractor serves several purposes.
The utility model is achieved in that increases hoisting winding, goods suspension hook assembly and body of the tower standard knot suspension hook on common tower concrete placing boom, adopt specific wire rope canoe, promote goods suspension hook assembly or body of the tower standard knot suspension hook with hoisting winding.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is that wire rope of the present utility model twines schematic diagram.
Existing accompanying drawings is as follows: pivoting support [26] is installed on the pylon [28].Slewing tower [29] is installed on the pivoting support [26].Turntable [5] is installed on the slewing tower [29].Big arm [11] is hinged with turntable [5], and the two ends of big arm oil cylinder [7] are hinged with turntable [5] and big arm [11] respectively.Middle arm [20] is hinged with big arm [11], and the both sides of hinged place are equipped with right pulley [16] and left chain wheel [30] respectively.The two ends of middle arm oil cylinder [12] are hinged with big arm [11] and middle arm connecting rod [13] respectively.Forearm [21] is hinged with middle arm [20], and forearm oil cylinder [22] is hinged with middle arm [20] and forearm connecting rod [23] respectively.After big arm [11], middle arm [20] and forearm [21] collapse, middle arm [20] and forearm [21] are hooked on the bottom of big arm [11] by drag hook [10].Drag hook [10] is hinged with big arm [11], and drag hook seat [24] is welded on forearm [21].Goods suspension hook assembly [19] pin [17] that is fixed is fixed in the suspension hook deck [18] of middle arm [20] afterbody.Suspension hook deck [18] and middle arm [20] welding.Counter-jib [2] is hinged with turntable [5].Balancing weight [1] is positioned at the afterbody of counter-jib [2].Hoisting winding [3] is positioned at the top of counter-jib [2].One end of wire rope [4] is fixed on the hoisting winding [3], the other end connects with body of the tower standard knot suspension hook [25] by the pulley [31] on the press rope wheel [6], left front support roller [15], left chain wheel [30], goods suspension hook assembly [19] and pulley [32], right pulley [16], right front support roller [14], back support roller [9], suspension hook block seat [8] again.
Now the course of work of the present utility model is described below:
When needs carry out concrete cloth operation, big arm oil cylinder [7] is stretched out, big arm [11] is lifted when facing upward about 60 ° angle, drag hook [10] is the drag hook seat [24] of one because of action of gravity breaks away from automatically with the forearm weldering, then, driving oil cylinder [12], [22] successively, arm in the stretching, extension [20] and forearm [21] just can carry out the cloth operation on the coagulation.
When needs lifting body of the tower standard knots [27], big arm [11], middle arm [20] and forearm [21] are collapsed entirely, and make drag hook [10] that drag hook seat [24] hook is good, goods suspension hook assembly [19] is fixed in the suspension hook deck [18] with steady pin [17], hoisting winding [3] loosens wire rope [4], body of the tower standard knot suspension hook [25] just can lift by crane the operation of body of the tower standard knot [27] because of action of gravity descends.
When needs lifted by crane other goods, arm [11], middle arm [20] and forearm [21] collapsed entirely greatly, and made drag hook [10] that drag hook seat [24] hook is good.After pulling out steady pin [17], hoisting winding [3] loosens wire rope [4].Because the weight of the weight ratio body of the tower standard knot suspension hook [25] of goods suspension hook assembly [19] is big more than two times, therefore goods suspension hook assembly [19] descends, stop and body of the tower standard knot suspension hook [25] rises to the lower end of the suspension hook shelves seat [8] that is contained in big arm [11], at this moment just can lift by crane the operation of other goods.
This implementation is novel have simple in structure, conversion is convenient, have the characteristics of a tractor serves several purposes.
Claims (1)
