Abstract
The utility model provides a folding arm support pin roll dismounting device, and relates to a construction crane. The folding arm support pin roll dismounting device is used for solving the technical problem that a conventional pin roll dismounting device causes the overrun of the width of the whole crane. The folding arm support pin roll dismounting device comprises a hydraulic oil cylinder which is arranged on a crane rotary table, wherein a cylinder barrel of the hydraulic oil cylinder is an arm support pin roll of the crane, namely the oil cylinder type pin roll and a piston rod form the hydraulic oil cylinder, the head of the piston rod is connected to a cross bar which is placed on a guiding frame fixed on the crane rotary table, and pin holes into which the location a and the location b of a stop bin can be inserted are formed in the guiding frame; and the guiding frame is formed by connecting a fixed mount and a bogie through a bolt. The folding arm support pin roll dismounting device is used for the construction crane and has the advantages of simple structure, convenience in dismantling, cost conservation and small land occupation after the guiding frame is folded.
Description
Technical field
The utility model relates to crane, particularly the attaching/detaching apparatus of crane boom pin.
Background technology
For heavy construction hoisting crane, when transition and transportation, jib part need to be dismantled from turntable, to avoid overweight.Conventional scheme is that the dismounting that auxiliary cylinder carries out bearing pin is set on rotating platform of crane at present, as shown in Figure 1.In bearing pin 01 inside, auxiliary cylinder 02 is set, bearing pin 01 is fixedly connected with by end baffle 03 with auxiliary cylinder 02.The piston rod 04 of auxiliary cylinder is fixedly connected with guiding trestle 05, and guiding trestle 05 is fixed on turntable 06.The horizontal extension of the cylinder barrel 07 by auxiliary cylinder 02 drives bearing pin 01 to move, thereby realizes the dismounting of bearing pin 01.
Pin assembling/disassembling structure shown in Fig. 1, its mounting distance is L1, at least should be greater than the stroke L of auxiliary cylinder 02.This structure is used on heavy construction hoisting crane and is easy to make car load width to exceed the 3m limit for width of national regulation.Meanwhile, outstanding this structure out on turntable, in rotation of rotary table process, also object or the staff easily and outside turntable bumps, and causes unnecessary trouble and danger.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, and a kind of folding boom pin attaching/detaching apparatus is provided, and solves the technical matters that current pin shaft dismounting device makes car load width overrun.
The utility model is achieved through the following technical solutions:
A kind of folding boom pin attaching/detaching apparatus, comprise: be arranged on the hydraulic ram on rotating platform of crane, it is characterized in that: the cylinder barrel of described hydraulic ram is crane arm support bearing pin, that is: cylinder type bearing pin and piston rod form hydraulic ram, the head of piston rod is connected with cross bar, cross bar is placed on the guide frame fixing with rotating platform of crane, and guide frame is provided with and can inserts the position a of backing pin and the pin-and-hole of position b; Described guide frame is formed by connecting with latch by fixed mount and bogie truck.
The utility model compared with prior art, due to a set of pin shaft dismounting device being set on rotating platform of crane, make cylinder type bearing pin under hydraulic oil effect, realize the dismounting of bearing pin, the guide frame after simultaneously folding reduces car load width effectively, has met the regulation of national legislation to overall width.
The utility model is for crane, have simple in structure, easy accessibility, cost-saving, the device little advantage that takes up room after guide frame is folding.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing crane arm support pin shaft dismounting device;
Fig. 2 is structural representation of the present utility model (bearing pin is in confined state);
Fig. 3 is the structural representation that piston rod stretches out bearing pin;
Fig. 4 is the structural representation that bearing pin is pulled out turntable completely;
Fig. 5 is structural representation of the present utility model (concrete structure of guide frame);

Below in conjunction with accompanying drawing, the utility model is described in further detail.
The specific embodiment
As shown in Figure 2-5, a folding boom pin attaching/detaching apparatus, comprising: be arranged on the hydraulic ram on rotating platform of crane, the cylinder barrel of described hydraulic ram is crane arm support bearing pin, that is: cylinder type bearing pin 1 forms hydraulic ram with piston rod 4, can utilize hydraulic principle work.The head of piston rod 4 is connected with cross bar 41, and cross bar 41 is placed on the guide frame fixing with rotating platform of crane 2, and guide frame 2 is provided with and can inserts the position a of backing pin 3 and the pin-and-hole of position b, and backing pin 3 is for preventing the parallel motion of piston rod 4; Described guide frame 2 is formed by connecting by fixed mount 21 and bogie truck 22 use latches 23.
Working process of the present utility model is as follows:
A, dismounting hinge pin process: Fig. 2 are initial condition, during dismounting, backing pin 3 are extracted by position b, and piston rod 4 oil-feeds make it along guide frame 2 horizontal left, during to range place, backing pin 3 are positioned over to position a to stop piston rod 4 oppositely to move, as shown in Figure 3.Piston rod 4 is drained the oil, and makes to serve as bearing pin 1 horizontal left of cylinder barrel, thereby bearing pin 1 is extracted from turntable, as shown in Figure 4.
B, bearing pin installation process: during installation, backing pin 3 is positioned at position a and moves to right to prevent piston rod 4, as shown in Figure 4.Piston rod 4 oil-feeds, make bearing pin 1 move to right with respect to piston rod 4 levels, pack turntable into, to range, as shown in Figure 3.Backing pin 3 is extracted, and piston rod 4 is drained the oil it is moved to right to complete retracted mode along guide frame 2 levels, and backing pin 3 is positioned over to position b, as shown in Figure 2, completes the installation of bearing pin 1.
As shown in Figure 2, the installation length of guide frame 2 is at least greater than the range of bearing pin 1, is therefore easy to make car load super wide, need be by folding rear placement of guide frame 2.
As shown in Figure 5, guide frame 2 consists of fixed mount 21, bogie truck 22 and latch 23.When bearing pin 1 is during in confined state, upper and lower two latches 23 of a side are extracted, promote bogie truck 22 and make it around two latches of opposite side 23, rotate 90 ° of folding placements, as shown in Figure 6.
The utility model be take cylinder tube as bearing pin, utilizes the flexible dismounting that realizes bearing pin of oil cylinder, simple in structure, and easy accessibility is cost-saving; Device after guide frame is folding takes up room little, effectively reduces car load width, is beneficial to transition and transportation.
