Abstract
The utility model relates to a lifting mechanism maintaining hanger rod of a self-lifting tower crane. Temporary lifting equipment is generally used for maintaining a lifting mechanism, and the methods are as follows: a gin pole is mounted at a position at an altitude of above 50 m, which has the disadvantage that the mounting of the gin pole is labor-consuming and troublesome; or a truck crane is used at a position at an altitude of around 30 m, which has the disadvantage that the cost is higher. A U-steel I (3) and a U-steel II (4) are connected with a main chord of a balance arm (1); a steel pipe (5) is connected with the U-steel I (3) and the U-steel II (4); a lifting rod (6) is inserted into the steel pipe of a bearing seat (5); and a nut (2) is in threaded connection with the lifting rod (6). Compared with the prior art, the lifting mechanism maintaining hanger rod can reduce the workload of mounting and demounting, save partial material cost and labor cost and reduce the maintenance cost of the lifting mechanism.
Description
One, technical field
The utility model is used for the lifting mechanism maintenance suspension rod of self-raising tower crane.
Two, background technology
The interim hanging device of general use when lifting mechanism is keeped in repair, method has two kinds: position more than 50 meters, gin pole is installed, shortcoming: gin pole is installed effort, trouble; Wheel crane is used in position, 30 meters left and right sides, and shortcoming: expense is bigger.
Three, utility model content
1 the utility model purpose: design a kind of maintenance suspension rod that is applicable to lifting mechanism, the lifting mechanism maintenance suspension rod that on self-raising tower crane, uses, can reduce the work capacity of Assembly ﹠Disassembly, save part fee of material and labour cost, reduce the service expenditure of lifting mechanism.
2. lifting mechanism maintenance suspension rod solution is: near channel-section steel I[3 equilibrium arm [1] lifting mechanism], channel-section steel II[4] be connected steel pipe [5] and channel-section steel I[3 with the main chord of equilibrium arm [1]], channel-section steel II[4] connect.Gib [6] inserts in the steel pipe of supporting base [5], and nut [2] links to each other with screw thread on the gib [6], and nut [2] is tightened.Adapter plate [8] is connected gib [6] vertical direction, from equilibrium arm [1] level 0.8 meter position upwards.Be installed on the adapter plate [8] connecting electric winch [9] with bolt pair [10].With sheave shaft [12] lower sheave [13] is installed in the hole at gib [6] middle part.Steel rope bearing pin [16] inserts in the hole of gib [10] upper end.Steel rope [11] one ends link to each other with electric winch [9], after steel rope [11] other end passes lower sheave [13] top sheave [17], pass lifting hook pulley [15] again and are upward through steel rope bearing pin [16] and later with wire clips [14] steel rope [11] are tightened.
3 the utility model are compared with known technology, can reduce the work capacity of Assembly ﹠Disassembly, save part fee of material and labour cost, reduce the service expenditure of lifting mechanism
Four, description of drawings
Accompanying drawing 1 is a lifting mechanism maintenance suspension rod front view.Accompanying drawing 2 is lifting mechanism maintenance suspension rod birds-eye vieies.
Five, specific embodiment
1,2 describe in conjunction with the accompanying drawings: near channel-section steel I[3 equilibrium arm [1] lifting mechanism], channel-section steel II[4] be connected steel pipe [5] and steel I[3 with the main chord of equilibrium arm [1]], channel-section steel II[4] connect.Gib [6] inserts in the steel pipe of supporting base [5], and nut [2] links to each other with screw thread on the gib [6], and nut [2] is tightened.Adapter plate [8] is connected gib [6] vertical direction, from equilibrium arm [1] level 0.8 meter position upwards.Be installed on the adapter plate [8] connecting electric winch [9] with bolt pair [10].With sheave shaft [12] lower sheave [13] is installed in the hole at gib [6] middle part.Steel rope bearing pin [16] inserts in the hole of gib [10] upper end.Steel rope [11] one ends link to each other with electric winch [9], after steel rope [11] other end passes lower sheave [13] top sheave [17], pass lifting hook pulley [15] again and are upward through steel rope bearing pin [16] and later with wire clips [14] steel rope [11] are tightened.Install the back and just can use in the lifting mechanism maintenance, lifting mechanism maintenance suspension rod can hang electrical motor, reel, drop-gear box, drg.
Claims (2)
1. a lifting mechanism maintenance suspension rod is characterized in that: channel-section steel I[3], channel-section steel II[4] be connected with the main chord of equilibrium arm [1], steel pipe [5] and steel I[3], channel-section steel II[4] connect, gib [6] inserts in the steel pipe of supporting base [5], and nut [2] links to each other with screw thread on the gib [6].
2. a kind of lifting mechanism maintenance suspension rod according to claim 1, it is characterized in that: adapter plate [8] is connected gib [6] vertical direction, from equilibrium arm [1] level 0.8 meter position upwards.
