Summary of the invention hangs limitation in order to overcome existing retractable vehicle, the utility model has designed a kind of telescopic boom crane that has Weighting system, Weighting system has been installed, on the front portion of telescopic boom foremost, a steel rope Connection Block has been installed, utilize winch to give power that makes progress of telescopic boom foremost, can improve the force-bearing situation of lifting arm preferably, increase effective hoisting weight of crane, strengthen the safety of crane.
The described telescopic boom crane that has Weighting system has a walking chassis, a revolution telescopic boom system and a Weighting system, and revolution telescopic boom system and Weighting system all are installed on the walking chassis.
On the walking chassis of the described telescopic boom crane that has a Weighting system four hydraulic rams are installed.
The revolution telescopic boom system of the described telescopic boom crane that has a Weighting system is by big gear wheel, rotary table, lifting arm, the winch of hoisting heavy, steel rope, big arm swing oil cylinder and suspension hook are formed, lifting arm is made up of big arm and telescopic boom, big gear wheel is installed on the walking chassis and maintains static, rotary table is installed in above the big gear wheel and is coaxial and can rotate around their common axis line with big gear wheel, rotary motor is installed on the rotary table, on the output shaft of rotary motor miniature gears has been installed, miniature gears and big gear wheel engagement, big arm is hinged by central rotating shaft and rotary table, in big arm the inside the hydraulic ram that telescopic boom stretches is installed, between big arm and the rotary table oil cylinder that drives big arm swing is installed, the winch of hoisting heavy is installed on the Weighting system, after the front end track adjusting wheel of its steel rope by telescopic boom foremost, connects a suspension hook, the steel rope Connection Block that upwards draws has been installed in the front portion of telescopic boom foremost.
The Weighting system of the described telescopic boom crane that has a Weighting system is by clump weight, the counterweight carriage, counterweight carriage sliding sleeve, driven wheel, two toothed rack, winch, steel rope, supporting gear, gear wheel shaft, ratchet and pawl is formed, the counterweight carriage is made up of two sliding bars and two clump weight clamping plate, two sliding bars and two breeding clamping plate are to link as a whole, clump weight is placed between two clamping plate, the following toothed rack of respectively having installed of two sliding bars, tooth bar both meshed with driven wheel, mesh with slip cap in-to-in supporting gear again, the gear wheel shaft of supporting gear is installed on the sliding sleeve, ratchet has been installed in the outside at an end sliding sleeve of gear wheel shaft, the ratchet supporting with ratchet also installed in the outside at sliding sleeve, the top circle hole sleeve of two carriage sliding sleeves is contained in the two ends of central rotating shaft, winch is installed on the carriage, its steel rope links to each other with Connection Block on the telescopic boom foremost, the following tooth bar engagement of driven wheel and counterweight carriage, driven wheel is installed on the walking chassis.
The telescopic boom crane that has Weighting system has following major advantage:
1, utilize Weighting system and winch to give power that makes progress of telescopic boom foremost, can improve the force-bearing situation of lifting arm preferably, increase effective hoisting weight of crane,
2, strengthen the safety of crane
3, the wearing and tearing of rotary system have been reduced.
Description of drawings is below in conjunction with the description of drawings specific embodiment of the invention:
Fig. 1 is the structural representation that has the telescopic boom crane of Weighting system
Fig. 2 is the structural representation of mode of operation that has the telescopic boom crane of Weighting system
Fig. 3 is the counterweight carrier structure scheme drawing that has the telescopic boom crane of Weighting system
Fig. 4 is the telescopic boom crane hydraulic principle scheme drawing that has Weighting system
As shown in FIG.: the 1-chassis of walking, 2-rotary motor, 3-rotary table, the 4-driven wheel, 5-tooth bar, 6-counterweight carriage, the 7-Weighting system, 8-clump weight, 9-steel rope, the 10-winch, 11-counterweight carriage slip cap, 12-central rotating shaft, 13-revolution telescopic boom system, the big arm of 14-, 15-suspension hook, 16-is telescopic boom foremost, the big arm swing oil cylinder of 17-, 18-ratchet, the 19-ratchet, 20-road wheel, 21-big gear wheel, the 22-miniature gears, 23-steel rope, 24-supporting gear, the 25-gear wheel shaft, 26-counterweight clamping plate, 27-counterweight carriage sliding bar, the 28-hydraulic efficiency pressure system, the three position four-way directional control valve of 29-rotary motor, 30-telescopic boom elongation oil cylinder, the three position four-way directional control valve of 31-elongation oil cylinder, 32-winch, 33-steel rope Connection Block, the 34-track adjusting wheel, the three position four-way directional control valve of the big arm swing oil cylinder of 35-.
The specific embodiment:
In Fig. 1 and Fig. 2, starter motor and hydraulic efficiency pressure system, operation three position four-way directional control valve 35, the big arm suitable angle of steeving, operation three position four-way directional control valve 31, telescopic boom 16 is foremost released the appropriate location, operation driven wheel 4 rotates counterclockwise, drive Weighting system by tooth bar 5 and be moved to the left to the appropriate location, because the effect of ratchet 19 and ratchet 18, Weighting system 7 can not slide to the right automatically, driving winch 32 earns steel rope 9 tightly, operation three position four-way directional control valve 35 commutates once more, the elevation angle of big arm 14 is reduced a little, driving Weighting system 7 by steel rope 9 rotates around central rotating shaft 12, it is upwards steeved, make tooth bar 5 leave driven wheel 4, Here it is mode of operation, start winch 10 then and HM Hydraulic Motor 2 is carried out hoisting heavy and revolution, when weight was put into assigned address, operation three position four-way directional control valve 35 suitably increased the elevation angle of big arm 14, make the tooth bar 5 and driven wheel 4 engagements of Weighting system 7, unclamp ratchet 19 and ratchet 18, allow driven wheel 4 clockwise rotate, drive tooth bar 5 and Weighting system 7 home position that moves right, reclaim telescopic boom 16, big arm 14 is dropped to the home position, start winch 10 and 32, steel rope 23 and 9 is regained, allow ratchet 19 contact, just finished a lifting operation to this with ratchet 18.
