Abstract
The invention discloses a double-head suspension tower crane, which is used for building, water conservancy, electricity, highways, stations, docks, petrifaction, nuclear power stations and other construction sites. The tower crane in the prior art is only provided with one crane boom and one head suspension, so the hoisting efficiency is not high. The observation front side of a cab [16] is parallel to a rotation tower body [9], the cab [16] is installed on an upper base [8], a lifting mechanism [11] which is installed on a crane boom [12] is arranged at the right side of the rotation tower body [9], the crane boom is arranged at the left side of the rotation tower body [9] of the tower crane, one end of a crane boom short drag rod [13] is obliquely arranged on the crane boom, the other end of the crane boom short drag rod [13] is obliquely arranged in the middle of a tower plate, and one end of a crane boom long drag rod [14] is obliquely arranged on the crane boom. Compared with the acknowledged technology, the hoisting efficiency of the tower crane is improved by one time.
Description
One, technical field
Two tower crane formula hoisting crane that use in building sites such as the present invention is used to build, water conservancy, electric power, highway, station, harbour, petrochemical industry, nuclear station.
Two, background technology
Existing technological tower crane has only one of a crane arm to hang, and lifting efficient is not high.
Three, summary of the invention
1. the objective of the invention is to design a kind of two tower crane formula hoisting crane; Tower crane removes equilibrium arm and balance arm brace, and a cover crane arm is installed again, a cover crane arm long draw, a cover crane arm short rod.All there is crane arm on the right side, the slewing tower left side of tower crane.
2. two tower crane formula hoisting crane is characterized in that: there is crane arm on the slewing tower left side of tower crane; Crane arm short rod one end is oblique on crane arm, and crane arm short rod one end is oblique in the middle of column plate, and crane arm long draw one end is oblique on crane arm; Crane arm long draw one end is oblique in the middle of column plate; The root of crane arm has lifting mechanism, and two on the pulley of tower head plate is symmetrical, and driver's cab is observed positive parallel with slewing tower apart.Driver's cab is installed, Yi Bian allow on the crane arm advertising panel is installed on upper bracket.The electrical apparatus control circuit of two tower crane formula hoisting crane is used known electrical apparatus control circuit, and the slewing tower right side also has lifting mechanism, luffing mechanism, suspension hook, the load-carrying dolly installed on the crane arm to be equal to that installed device is the same model and specification on the crane arm on the left side.The installation method of two tower crane formula hoisting crane have with, install the pinnacle of a pagoda after, the slewing tower height is about 22m; Will become splayed to fix with two steel cable wind ropes on the slewing tower, brake swing type mechanism, crane arm installs back (following installation is all pressed existing regulation and installed) by existing standard; Lifting mechanism is installed again; At the crane arm that steel cable wind rope opposite is installed, install with the crane arm of crane lifting, with rising mechanism's pull-up respectively; Crane arm short rod, crane arm long draw are installed, after crane arm, crane arm pull bar install.Steel cable wind rope the crane arm here is installed again, and with rising mechanism's pull-up respectively, crane arm short rod, crane arm long draw are installed, after crane arm, crane arm pull bar install.Dismantle the steel cable wind rope.Unclamp slewing gear brake.After hanging by existing standard mode, test run, examination, use by safety supervision approval back.
3. the present invention compares with known technology, and tower crane lifting efficient doubles, and practices thrift 30% manufacturing cost, practices thrift a body of the tower, practices thrift a basic expense, practices thrift 15% transportation volume.
Four, description of drawings
Accompanying drawing 1 of the present invention is a front view, and accompanying drawing 2 of the present invention is a planar view.
Five, the specific embodiment
Describe in conjunction with accompanying drawing 1,2: foundation for tower crane as prescribed is at the scene built, and base section [3] is upward installed (following installation all has by existing regulation installation) by existing regulation at foundation for tower crane [1], with the fastening base section of nut [2] [3]; Upward installation code joint [4] is with the secondary fastening standard knot [4] of high strength bolt for base section [3], and standard knot [4] is gone up undersetting [7] is installed, the following stock [6] of installing of undersetting [7]; Undersetting is equipped with pivoting support on [7], and upper bracket [8] is installed on the pivoting support, goes up at upper bracket [8] driver's cab [16] is installed; Go up installation slewing tower [9] at upper bracket [8]; Slewing tower [9] go up to be installed pinnacle of a pagoda [10], install pinnacle of a pagoda [10] after, slewing tower [9] height is about 22m; To become splayed to fix with two steel cable wind ropes on the slewing tower [2], brake swing type mechanism.Go up installation lifting mechanism [11], luffing mechanism, load-carrying dolly at crane arm [12].The crane arm [12] on steel cable wind rope opposite is installed; With crane lifting crane arm [12], the otic placode hole of crane arm links to each other with the otic placode hole of bearing pin with slewing tower [2], with rising mechanism [11] pull-up respectively; Crane arm short rod [13], crane arm long draw [14] are installed; The suspension centre hole of crane arm links to each other with the otic placode hole of pull bar with bearing pin, and the otic placode hole of pull bar links to each other with the hole of tower head plate, after crane arm, crane arm pull bar install.Steel cable wind rope the crane arm here is installed again.After connecting into an integral body to crane arm [12] earlier, lifting mechanism [11], luffing mechanism, load-carrying dolly are installed at crane arm [12].Crane arm [12] with crane lifting; With rising mechanism [11] pull-up respectively, crane arm short rod [13], crane arm long draw [14] are installed, and the suspension centre hole of crane arm links to each other with the otic placode hole of pull bar with bearing pin; The otic placode hole of pull bar links to each other with the hole of tower head plate, after crane arm rises, the weighing arm pull bar installs.Also to install the suspension hook on both sides.Allow on the crane arm advertising panel is installed on one side.Dismantle the steel cable wind rope.Unclamp slewing gear brake.After hanging by existing standard mode, test run, examination, use by safety supervision approval back.
Claims (1)
1. two tower crane formula hoisting crane, driver's cab [16] are observed positive and slewing tower [9] at a distance of parallel, go up installation driver's cab [16] at upper bracket [8]; Slewing tower [9] right side also has a crane arm [12] to go up the lifting mechanism of installing [11]; It is characterized in that: there is crane arm on the slewing tower of tower crane [9] left side, and crane arm short rod [13] one ends are oblique on crane arm, and crane arm short rod [13] one ends are oblique in the middle of column plate; Crane arm long draw [14] one ends are oblique on crane arm; Crane arm long draw [14] one ends are oblique in the middle of column plate, and the root of crane arm [12] has lifting mechanism [11], [15] two on the both sides pulley of tower head plate.
