Abstract
The present invention is a kind of crawler crane, including getting off and getting on the bus, also include bore operation device, reinforced basic arm activity on mast installation and crane it is hinged, amplitude modulation oil cylinder and leveling cyclinder one end are hinged in mast installation, the reinforced basic arm activity on the other end of amplitude modulation oil cylinder and leveling cyclinder and crane it is hinged；Unit head is provided with mast installation, the pipe that the input port of the power source of unit head passes through in the mast installation that is located at is connected with the power output mouth of the high pressure fuel source on the reinforced basic arm on crane, described drilling rod assembly is arranged on the output end of unit head, described drilling tool is arranged on the bottom of drilling rod assembly, and the top of drilling rod assembly is connected by rope with the medium-sized raising elevator on crane.Contrast prior art, the present invention is when crawler crane runs into hard rock in bore operation, usable power puts type elevator and carries out rock fracture in dynamic indentation soon, greatly improve operating efficiency, shorten construction period, and then the high performance-price ratio and efficiency of construction of product are improve, and product competitiveness in the market is enhanced, meet the requirement of national energy-saving emission reduction.
Description
Technical field
The present invention relates to a kind of stepless luffing device, specifically a kind of crawler crane is filled with the stepless luffing of combined type auxiliary
Put, belong to crane technical field.
Background technology
Crawler crane is that hoisting operation is partially contained on crawler body, and walking relies on the flow-type lifting of crawler attachment
Machine.Crawler crane can carry out the operations such as material lifting, transport, handling and installation.Crawler crane have elevating capacity it is strong,
Grounding pressure is small, radius of turn is small, climbing capacity is big, be not required to supporting leg, belt carrying running, job stabilization are good and truss combination is high
The advantages of degree can be changed freely, is widely used in construction industries such as electric power, municipal administration, bridge, petrochemical industry, water conservancy and hydropowers.
At present, in the market crane mainly has two kinds of luffing device forms, principal arm, the angle form of auxiliary be divided into it is fixed,
Two kinds of variable.The former can only realize the angle of several fixations（Major-minor arm angle）, meanwhile, adjusting angle is unable in working order
Degree, limits the performance of auxiliary performance；The latter's oil cylinder receives luffing power, and security, reliability have hidden danger.
The content of the invention
For the problem that above-mentioned prior art is present, the present invention provides a kind of crawler crane stepless change of combined type auxiliary
Width device, forms dual security protection, improves security, realizes stepless luffing, while reducing the length of oil cylinder, reduces oil cylinder
Production cost and technical difficulty.
To achieve these goals, the present invention includes arm-tie, auxiliary support and auxiliary post-tensioning before principal arm 1, auxiliary, auxiliary
Plate；Also include stepless luffing device；Stepless luffing device is arranged on after auxiliary in arm-tie, by oil cylinder, drag-line and set square structure
Into, wherein, oil cylinder is by the way that in arm-tie after the set square at two ends is fixed on auxiliary, the two ends of drag-line are separately mounted to oil cylinder two ends
On set square.
Further, drag-line sets two, is installed in parallel on the set square at oil cylinder two ends.
Further, length of oil cylinder is not more than the maximum displacement of drag-line.
Further, stepless luffing device is movably arranged on after auxiliary in arm-tie.
Further, stepless luffing device can be replaced regular length arm-tie component.
Further, the angular range of stepless luffing device may be selected（10°-30°）With（30°-60°）Two kinds of different operating modes.
Contrast prior art, the present invention realizes fixing the stepless luffing of auxiliary by adjusting the length of oil cylinder：Oil cylinder group
Oil cylinder, drag-line are arranged in parallel in part.When adjustment length of oil cylinder is no more than maximum displacement, drag-line keeps relaxed state；Reach oil cylinder
Range when, drag-line is tightened, stress, and dual security protection is formed together with oil cylinder, improves security.In addition,
The adjustment combined by arm-tie, the regular length after adjustment in arm-tie, the angular range of stepless luffing may be selected and two kinds of differences
Operating mode, the method is substantially reduced the length of oil cylinder, reduces the production cost and technical difficulty of oil cylinder.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of crawler crane stepless luffing device of combined type auxiliary, including principal arm 1, auxiliary 2, auxiliary
Preceding arm-tie 3, auxiliary support 4 and arm-tie 5 after auxiliary；Also include stepless luffing device；As shown in Fig. 2 described stepless luffing dress
Put after auxiliary in arm-tie 5, be made up of oil cylinder 6, drag-line 7 and set square 8, wherein, described oil cylinder 6 is by two ends
Set square 8 is fixed on after auxiliary in arm-tie 5, and the two ends of described drag-line 7 are separately mounted on the set square 8 at the two ends of oil cylinder 6.
Used as further improvement of the invention, drag-line 7 sets two, is installed in parallel on the set square 8 at the two ends of oil cylinder 6.
Used as further improvement of the invention, the length of oil cylinder 6 is not more than the maximum displacement of drag-line 7.
Improved as of the invention further, stepless luffing device is movably arranged on after auxiliary in arm-tie 5.
Used as further improvement of the invention, stepless luffing device can be replaced regular length arm-tie component.
Used as further improvement of the invention, the angular range of stepless luffing device may be selected 10 ° -30 ° with 30 ° -60 ° two
Plant different operating modes.
Contrast prior art, the present invention realizes fixing the stepless luffing of auxiliary by adjusting the length of oil cylinder：Oil cylinder group
Oil cylinder, drag-line are arranged in parallel in part.When adjustment length of oil cylinder is no more than maximum displacement, drag-line keeps relaxed state；Reach oil cylinder
Range when, drag-line is tightened, stress, and dual security protection is formed together with oil cylinder, improves security.In addition,
The adjustment combined by arm-tie, the regular length after adjustment in arm-tie, the angular range of stepless luffing may be selected and two kinds of differences
Operating mode, the method is substantially reduced the length of oil cylinder, reduces the production cost and technical difficulty of oil cylinder.
