Abstract

The utility model relates to a folding type bearing mechanism of a crawler crane. The bearing mechanism is mainly used for supporting the whole cranes on working conditions that crawler belt devices of small and medium tonnage crawler cranes are assembled and disassembled. The folding type bearing mechanism of the crawler crane is mainly composed of a bearing oil cylinder and an oil cylinder support, wherein the oil cylinder support is hinged between an upper cover plate of the lower crane and a lower cover plate of the lower crane through supporting shafts, the bearing oil cylinder is hinged on the oil cylinder support, a positioning pin hole and a positioning shaft are arranged at connection positions of supporting shafts and the lower crane, a locking pin hole and a locking shaft are arranged at the connection position of the oil cylinder support and the bearing oil cylinder, and a bearing base which is connected movably is arranged at the bottom of the bearing oil cylinder. According to the bearing mechanism, by the aid of left-and-right rotation of the oil cylinder support and up-and-down rotation of the bearing oil cylinder, during transportation of the crane, the body width of the crane and the height of the bottom of the lower crane are not affected by the bearing mechanism, and the good trafficability characteristic. The bearing mechanism is located between the upper cover plate of the lower crane and the lower cover plate of the lower crane, so that the installation space is saved. The bearing mechanism is simple in structure, easy to operate, safe and reliable.

Description

The collapsible Zhi Chongji structure of crawler crane
One, technical field
The utility model relates to the Zhi Chongji structure of crawler crane, the support of car load when being mainly used in medium and small tonnage caterpiller crane crawler attachment assembly and disassembly operating mode.
Two, background technology
During the crawler attachment Assembly ﹠Disassembly of medium and small tonnage caterpiller crane, the lifting of car load is to realize by the Zhi Chongji structure of getting off.There are two problems in existing Zhi Chongji structure: (one) cylinder bracket is in the outside of getting off, and lower vehicle-width is limited by cylinder bracket, affects the transportation of truck-load width.(2) prop up the heavy oil cylinder and be subjected to stroke limitation, mounting distance can't dwindle, and its lower surface often is lower than the lower surface of getting off, and causes the car load crossing ability to reduce, transport difficulty.
Three, summary of the invention
The purpose of this utility model provide a kind of can save crawler crane get off installing space, increase the collapsible Zhi Chongji structure of crawler crane of the crossing ability of getting off.
The technical scheme of employing of the present utility model is: the collapsible Zhi Chongji structure of crawler crane mainly is made of a heavy oil cylinder and cylinder bracket, and cylinder bracket is hinged on by pivot shaft and gets off between the upper and lower cover plate, and a heavy oil cylinder is hinged on the cylinder bracket; In pivot shaft and the junction of getting off dowel hole and fix shaft are arranged, in cylinder bracket and the junction of propping up the heavy oil cylinder lock pin holes and lock shaft are arranged, the supporting base of flexible connection is arranged in a heavy oil cylinder bottom section.Cylinder bracket of the present utility model can pivot shaft be inner rotary in the axle center, and by fix shaft, the position rotating angle, and a heavy oil cylinder to be rotating up and down as the axle center with the cylinder bracket adapter shaft, and by lock shaft, locks lower angle on it.The utility model uses when crawler crane dismounting track frame, during use first with cylinder bracket to inner rotary, rotate to the dowel hole place and lock with fix shaft, then will prop up heavy oil cylinder lock shaft and extract, a heavy oil cylinder is rotated down, rotate to the lock pin holes place, lock with lock shaft, installation bearing seat just can be propped up car load by cylinder control system, carries out the track frame disassemble and assemble work.The utility model is by the left rotation and right rotation of cylinder bracket and the up and down rotation of a heavy oil cylinder, and when hoisting crane was transported, its width over sides of car body and the bottom level of getting off were not affected by the Zhi Chongji structure, have preferably crossing ability.The Zhi Chongji structure is in gets off between the upper and lower cover plate, saves lower installing space.A kind of simple in structure, processing ease, safe and reliable Zhi Chongji structure.

Fig. 4 is of the present utility model heavy oil cylinder assembly path of motion schematic diagram;
Fig. 5 is the installation site schematic diagram of the utility model on crawler crane.
Five, the specific embodiment
The utility model forms the Zhi Chongji structure of getting off by cylinder bracket 2, a heavy oil cylinder 7.Cylinder bracket 2 is hinged on by pivot shaft 3 and gets off between the upper and lower cover plate 17,18, and pivot shaft 3 is fixed on the upper cover plate 17 of getting off by clip arrangement 1.Prop up heavy oil cylinder 7 and pack into by cylinder bracket 2 guide holes, with adapter shaft 8 places of cylinder bracket 2 shaft-cup of connection 10 and axle sleeve 11 are arranged at a heavy oil cylinder 7, connect shaft-cup 10 and be fixed on the cylinder bracket 2 by bolt 9 with axle sleeve 11.For guaranteeing heavy oil cylinder 7 smooth running, have oil guide groove at the adapter shaft 8 that props up heavy oil cylinder 7 and cylinder bracket 2, the lubricating cup 12 that connects oil guide groove is arranged at adapter shaft 8 spindle noses, can carry out oiling by lubricating cup 12, have oil groove in the axle sleeve 11, can store lubricating oil, guarantee that a heavy oil cylinder 7 rotations are level and smooth.
Base frame at pivot shaft 3 has left dowel hole 13 and right dowel hole 14, and when cylinder bracket 2 left-right rotation, left dowel hole 13 can be corresponding with the pin-and-hole on the lower cover 18 of getting off respectively with right dowel hole 14.At cylinder bracket 2 lower lock pin holes 15 and upper lock pin holes 16 are arranged, at a heavy oil cylinder 7 lock pin holes is arranged, when a heavy oil cylinder rotated up and down, the lower lock pin holes 15 on the cylinder bracket 2 can be corresponding with the lock pin holes on the heavy oil cylinder 7 respectively with upper lock pin holes 16.
Collapsible Zhi Chongji structure working process: during work, first fix shaft 4 is extracted from left dowel hole 13, promoted cylinder bracket 2 to inner rotary, when rotation to right dowel hole 14 overlaps with the lower cover dowel hole of getting off, fix shaft 4 is inserted the location.So far inside and outside jackknife action is finished.After inside and outside jackknife action is finished, lock shaft 5 is extracted from upper lock pin holes 16, will prop up heavy oil cylinder 7 and be rotated down when overlapping with lower lock pin holes 15 to the oil cylinder lock pin holes, lock shaft 5 insertions are locked.So far jackknife action is finished up and down.After above-mentioned two-step action is finished, supporting seat 6 is put into heavy oil cylinder 7 bottom, the operation hydraulic control system just can realize car load support part, carries out crawler attachment installation and removal process.
Collapsible Zhi Chongji structure removal process: be exactly the removal process of this collapsible Zhi Chongji structure with the working process reverse operating, whole mechanism structure is simple, and is easy to operate, safe and reliable.
