Abstract
The utility model discloses in a kind of torque arm and fill lift arm and linkage rack oil cylinder locking device, be made up of lift arm and linkage rack, being front end is arranged on the axle bed of linkage rack with the hammerlock body of latch hook by S. A., the lock dog coordinated with the latch hook of hammerlock body is fixedly mounted on lift arm, the two ends of oil cylinder are hinged on linkage rack and hammerlock body respectively, the utility model has that state of kinematic motion is directly perceived, symmetrical, uniform force, the feature that compact conformation, coupling mechanism force are large.
Description
Technical field
The utility model belongs to the catch gear technical field of assembling system on lifting hook, especially relates to a kind of oil cylinder and controls lifting hook lift arm and linkage rack latching device, be suitable for the structural development of assembling system in torque arm.
Background technology
At present, on the torque arm car of domestic use, assembling system lift arm and linkage rack catch gear are divided into two kinds: bottom latch formula catch gear and spring link formula catch gear; Bottom latch formula catch gear, the outside state of kinematic motion that cannot see this mechanism of machine of dress in torque arm, and this structure stress is uneven, affects stability during work.Spring link formula catch gear, although overcome bottom latch formula catch gear to there is the even state of kinematic motion of unbalance stress not problem intuitively, instead of bottom latch formula catch gear gradually, but because the restraining spring pulling force of size is not enough, for a long time tension fatiguability pulling force reduce, stability when affecting work and safety.
Summary of the invention
The purpose of this utility model with the deficiency improving prior art and provide that a kind of state of kinematic motion is directly perceived, symmetrical, uniform force, the torque arm that compact conformation, coupling mechanism force are large fills lift arm and linkage rack oil cylinder locking device.
The purpose of this utility model realizes like this, a kind of torque arm fills lift arm and linkage rack oil cylinder locking device, be made up of lift arm and linkage rack, be characterized in that front end is arranged on the axle bed of linkage rack with the hammerlock body of latch hook by S. A., the lock dog coordinated with the latch hook of hammerlock body is fixedly mounted on lift arm, and the two ends of oil cylinder are hinged on linkage rack and hammerlock body respectively.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is stretched out by HYDRAULIC CONTROL SYSTEM hydraulic actuating cylinder and drives hammerlock body, hammerlock body is rotated by S. A., thus be combined with lock dog, realize lift arm to be combined with the motion of linkage rack, even if hydraulic efficiency pressure system has auto-lock function, under the impact of external force, hydraulic actuating cylinder also can not automatic telescopic, thus to ensure in the process of work uniform force, safe and reliable; The utility model mainly solves lifting hook at work, the problem that unstable properties, safety performance are low, has following characteristics:
1, coupling mechanism force is large, such as specified hydraulic system pressure 20MPa, and now oil cylinder locking power is at 14KN, and spring maximum pull is between 1KN-2KN;
2, hydraulic ram can realize auto-lock function, and hydraulic efficiency pressure system is with the bidirectional hydraulic lock control oil cylinder of auto-lock function, even if oil cylinder also can not automatic telescopic under the impact of external force, and spring can shrink by under external force, and safety performance is high;
3, install, easy to maintenance;
4, HYDRAULIC CONTROL SYSTEM is easy to operate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is a kind of open mode constructional drawing of the present utility model.
Fig. 3 is a kind of locking state constructional drawing of the present utility model.
Detailed description of the invention
A kind of torque arm fills lift arm and linkage rack oil cylinder locking device, with reference to Fig. 1, Fig. 2, Fig. 3, being front end is arranged on the axle bed on linkage rack 6 with the hammerlock body 2 of latch hook by S. A. 3, the lock dog 4 coordinated with the latch hook of hammerlock body 2 is fixedly mounted on lift arm 5, the two ends of oil cylinder 1 are hinged on linkage rack 6 and hammerlock body 2 respectively, hammerlock body 2 is driven by HYDRAULIC CONTROL SYSTEM hydraulic ram 1 is flexible, hammerlock body 2 is rotated by S. A., thus the latch hook realizing hammerlock body 2 front end carries out being separated or locking with lock dog 4, realize the moved apart of lift arm 5 and linkage rack 6.
