Description
Technical field
The utility model relates to runabout crane, particularly the caterpillar telescopic boom crane.
Background technology
Generally two kinds commonly used of the runabout cranes of prior art.A kind of as Fig. 1: crawler body adds the hoisting crane of truss arm, is mainly used in the lifting operation of big elevating capacity.Shortcoming is hoisting capacity when increasing, and truss arm configuration complexity is out of shape greatlyyer, and mechanism is more, and material and manufacturability are had relatively high expectations.Another kind of as Fig. 2: automobile or All-terrain chassis add the hoisting crane of box-shaped arm, are mainly used in the lifting operation of little hoisting capacity.Shortcoming is that the box-shaped arm increases with joint number, and weight is bigger, poor stability, and lifting altitude is also restricted, and simultaneously, carrying capacity of chassis is limited, the welding process complexity, the turntable space is little, and the parts layout is difficulty comparatively.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of caterpillar telescopic boom crane is provided, and crane structure complexity, manufacturing process difficulty that the existing crawler body of solution adds the truss arm are big; Automobile or All-terrain chassis add the technical matters that crane stability is poor, carrying capacity of chassis is little of box-shaped arm.
The utility model is achieved through the following technical solutions:
A kind of caterpillar telescopic boom crane comprises: arm, Y type surpass, pivoting support, turntable, counterweight, crawler body, supporting leg, amplitude oil cylinder.Crawler body is connected with pivoting support with turntable, and counterweight is placed in the turntable back, and hoist hoisting mechanism, power and hydraulic efficiency gear are placed in the turntable middle part, anterior arm and the driver's cab installed of turntable, arm is connected with turntable, and the arm root is equipped with amplitude oil cylinder, and crawler body is equipped with supporting leg.It is characterized in that: the reductor that motor drives is housed on four angles of the track frame of described crawler body, and described crawler body is connected with the fast disassembly type pivoting support with described turntable; Described arm is the flexible box-structures of eight joints, relies on single cylinder insert-pull pin mechanism flexible between the arm joint, and there are four principal arm support oil cylinders the described arm of first segment outside, and support oil cylinder can support arm after launching; The Y type that the head of the described arm of first segment is equipped with two struts surpasses, a cover hoisting mechanism is equipped with at the head A place of each strut, the root of each strut is equipped with and has surpassed the anti-dumping oil cylinder, the steel rope that comes out from hoisting mechanism is connected with the head of described arm, captives joint with rope row between the head A place of described strut and the described turntable.
The utility model compared with prior art has the following advantages and beneficial effect:
1, owing at four angles of track frame the reductor that motor drives is housed, realize the moving walking of crawler body 4 wheel driven, the driver train volume is little, and is in light weight, and service requirement is strong, but pivot turn.
2, owing to employing fast disassembly type pivoting support, the separation of convenient for passenger to get on and off, the built-up time of minimizing car load has improved transportation transition efficient.
3, because arm uses single cylinder insert-pull pin technology, operation is simpler, stable during hoisting heavy.The arm support oil cylinder makes car load easy to assembly, quick, has improved from the dismounting ability.
4, use the Y type to surpass, can effectively alleviate the arm deadweight, complete machine structure is simple, and load-carrying ability is big, especially is fit to be provided in the hoister in large tonnage.

The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Shown in Fig. 3,4,5,6, a kind of caterpillar telescopic boom crane comprises: arm 1, Y type have surpassed 2, pivoting support 3, turntable 4, counterweight 5, crawler body 6, supporting leg 7, amplitude oil cylinder 8.Crawler body 6 is connected with turntable 4 usefulness pivoting supports 3, counterweight 5 is placed in turntable 4 back, hoist hoisting mechanism, power and hydraulic efficiency gear are placed in turntable 4 middle parts, turntable 4 anterior arm 1 and the driver's cabs installed, arm 1 is connected with turntable 4, arm 1 is equipped with amplitude oil cylinder 8, and crawler body 6 is equipped with four oil cylinder supporting legs 7; The reductor that motor drives is housed on four angles of the track frame of described crawler body 6, described crawler body 6 is connected with turntable 4 usefulness fast disassembly type pivoting supports, described arm 1 is the flexible box-structures of eight joints, rely on single cylinder insert-pull pin mechanism flexible between the arm joint, there are four principal arm support oil cylinders 1.1 first segment arm outside, can support arm 1 after support oil cylinder 1.1 launches; The Y type that the head of the described arm 1 of first segment is equipped with two struts 2.3 has surpassed 2, a cover hoisting mechanism is equipped with at the head A place of each strut 2.3, the root of each strut 2.3 is equipped with and has surpassed anti-dumping oil cylinder 2.2, the steel rope 2.1 that hoisting mechanism comes out is connected with the head of described arm 1, captives joint with rope row 2.4 between the head A place of strut 2.3 and the turntable 4.
The utility model adopts the narrow gauge crawler body, ground contact length * track center distance: 8.68 * 3.3m, the maximum ground connection width of crawler belt 4.8m.Span when supporting leg launches (laterally * vertically): 13 * 13m.Turntable adopts the high tensile steel plate welding, and counterweight is placed in the back, and major-minor hoist hoisting mechanism, power and hydraulic efficiency gear are placed in the middle part, anterior arm is installed and can swing up and down, the rotating driver's cab in the left and right sides.
The box arm comprises eight joint arms, relies on single cylinder insert-pull pin mechanism flexible between the arm joint, according to operating mode, and assembled length 18.3～100m.There are four principal arm support oil cylinders 1.1 first segment arm outside, and as shown in Figure 4, when arm and hoisting crane assembling, support oil cylinder launches, and supports arm 1, and the crawler vehicle motion can realize the quick link of principal arm.
As shown in Figure 5, two struts 2.3 having surpassed of Y type are contained in the head of first segment arm.A cover hoisting mechanism is equipped with at the head A place of each strut, and root is equipped with and has surpassed anti-dumping oil cylinder 2.2.The steel rope 2.1 that hoisting mechanism comes out is connected with the head of arm, captives joint with rope row 2.4 between the head A place of strut and the turntable.
The utility model principle of work: a part of power of combustion engine finally drives crawler travel, in the driving process, and the speed per hour of normally walking 0.23km/h, F-Zero reaches 1.26km/h, max. climb slope 17.6%, average unit pressure of ground 0.14MPa, at this moment, supporting leg is packed up along the crawler belt direction.During handling large-tonnage article, supporting leg launches, supporting ground, and caterpillar block breaks away from ground.The fast disassembly type pivoting support can be realized getting on or off the bus and splice fast, during work, realizes getting on the bus around 360 ° of unrestricted rotations of getting off.The luffing of arm is realized by amplitude oil cylinder.When arm does not have hoisting heavy, to surpass the anti-dumping oil cylinder earlier and adjust to appropriate length, the Y type has surpassed stationkeeping, the head A place of strut and the row of the rope between the turntable are in relaxed state, hoisting mechanism with the head A place of strut drives the prior pretension of steel rope, in the working process, the head A place hoisting mechanism of strut quits work.During the handling weight, under the weight effect, the arm first half is wanted downwarp, and steel rope 2.1 and rope row 2.4 just in time bear pulling force simultaneously, prevent the arm downwarp.The rated load weight of this hoisting crane can reach 1200 tons.
