Abstract
The utility model discloses a kind of novel crawler-type telescopic arm crane, comprise gantry body, described gantry body comprises creeper undercarriage, chassis, turn table, counterweight, telescopic jib, luffing mechanism and lift system, described gantry body is also provided with ground flattening mechanism, for carrying out screed operation to ground, so that described creeper undercarriage is walked on the ground or is worked all be in optimum level state.The utility model can utilize self leveling function, before hanging loads, carry out screed operation to ground, thus the horizontality making fuselage reach best, reduce the risk causing hoisting crane to tumble because ground is uneven; The cost simultaneously avoiding organizing extra instrument or equipment to carry out ground leveling and produce and expense; The utility model has the economy of advance functionally and practical application.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of novel crawler-type telescopic arm crane with leveling function.
Background technology
Crawler telescopic arm hoisting machine is made up of parts such as creeper undercarriage, chassis, turn table, telescopic jib, lift systems.In lift heavy operation process, require that fuselage is in relative level state all the time, its permissible angle of heel degree, according to different designs, all will limit within the specific limits.Therefore, the planeness on ground just becomes the key factor affecting crawler crane safe operation.
Existing crawler crane, before operation, all will be cleared up ground by extra various instrument or equipment (as road grader, bulldozer or digging machine) and flatten, until the planeness on ground reaches the safe operation requirement of crawler crane.
But above-mentioned this mode needs to organize extra manpower and materials, has both increased cost, has affected work efficiency, can not ensure again smooth after ground and crawler body plane fit like a glove.If condition is not enough in work-yard, or workman can not understand the technical requirements of ground leveling completely, then there is great potential safety hazard.
Utility model content
Technical problem to be solved in the utility model, proposes a kind of novel crawler-type telescopic arm crane exactly, can utilize the leveling function of self, before hoisting crane hangs loads, carry out screed operation to ground, thus makes the horizontality that fuselage reaches best.
For solving the problems of the technologies described above, technology of the present utility model by the following technical solutions:
A kind of novel crawler-type telescopic arm crane, comprise gantry body, described gantry body comprises creeper undercarriage, chassis, turn table, counterweight, telescopic jib, luffing mechanism and lift system, described gantry body is also provided with ground flattening mechanism, for carrying out screed operation to ground, so that described creeper undercarriage is walked on the ground or is worked all be in optimum level state.
On the basis of the above, the technical solution of the utility model can also do following improvement:
As preferably, described ground flattening mechanism comprises arcwall face dozer, strut bar and hydraulic ram, and described dozer is connected with described chassis front end by described strut bar and hydraulic ram, and described hydraulic ram controls raising of described dozer and lowers.
As preferably, the pilot piping of described hydraulic ram is integrated in the hydraulic efficiency pressure system of described gantry body.
As preferably, different according to hoisting crane tonnage, described hydraulic ram is single oil cylinder or two oil cylinder.
As preferably, the width of described dozer is more than or equal to the width between the traveling crawler of described gantry body, width between traveling crawler is the ultimate range width between traveling crawler, thus within ensureing that the walking path of traveling crawler is in the leveling scope of dozer all the time.
Compared with prior art, the beneficial effect that the utility model has is:
(1) advance functionally: crawler telescopic arm hoisting machine of the present utility model has the leveling function of original creation, when not by external tool and equipment, just can complete the screed operation to ground by hoisting crane chaufeur one people;
(2) reliability of operation effectiveness: compare the screed operation using external tool or equipment, dozer and chassis link together, in flattening course, dozer driving surface and descending traveling crawler are in same plane, ground after leveling is more conducive to hoisting crane and is in horizontality, reduces the risk causing hoisting crane to tumble because ground is uneven;
(3) economy applied: without the need to spending extra manpower and materials to carry out screed operation to ground, use manpower and material resources sparingly cost, saves the time, increases work efficiency.

Detailed description of the invention
For the understanding the utility model making those skilled in the art more clear and intuitive, below in conjunction with accompanying drawing, the utility model is further described.
Be preferred embodiment of the present utility model as Figure 1-Figure 2.
A kind of novel crawler-type telescopic arm crane, comprise gantry body 1, gantry body 1 comprises creeper undercarriage 2, chassis 3, turn table 4, counterweight 5, telescopic jib 6, luffing mechanism 7 and lift system 8, gantry body 1 is also provided with ground flattening mechanism 9, for carrying out screed operation to ground, so that described creeper undercarriage is walked on the ground or worked all be in optimum level state, wherein
Ground flattening mechanism 9 comprises the dozer 10 of arcwall face, strut bar 11 and hydraulic ram 12, the front end of dozer 10 with chassis 3 is connected by strut bar 11 and hydraulic ram 12, hydraulic ram 12 controls raising of dozer 10 and lowers, the pilot piping of hydraulic ram 12 is integrated in the hydraulic efficiency pressure system of gantry body 1, different according to hoisting crane tonnage, hydraulic ram 12 can be single oil cylinder or two oil cylinder, the width of dozer 10 slightly larger than gantry body 1 traveling crawler between ultimate range width, thus within ensureing that the walking path of traveling crawler is in the leveling scope of dozer 10 all the time.
When hoisting crane enters a new working environment, when needing to carry out screed operation to ground, hydraulic ram 12 first controls dozer 10 and lifts, after gantry body 1 drives to desired location, lower and start gantry body 1 after dozer 10 and push ahead, ground is cleared up and screed operation.Need in whole process to keep straight-line travelling, and guarantee that elevator boom rack is retracted completely, angle is no more than 30 degree, combination lantern is in alert status of glittering.When after the screed operation completing whole presumptive area, hydraulic ram 12 controls dozer 10 and lifts, and then hoisting crane carries out normal lifting operation again on smooth ground.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
