Description
Technical Field
The utility model belongs to the technical field of it prevents weighing down the auto-lock to lift by crane, concretely relates to manual lifting prevents weighing down self-lock device.
Background
The transmission line poles and towers are mostly in mountains and mountains, and in the daily maintenance and hoisting process, workers mostly use manual hoisting, and are forced to select manual hoisting due to heavy motor-driven winching or other hoisting devices. Various special conditions can be met in the manual lifting process, so that lifting workers can loosen hands, lifting objects fall off and are damaged, and the safety risk that the objects fall off and hurt people exists.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: provides a manual hoisting anti-falling self-locking device, which solves the problems in the prior art.
The utility model discloses the technical scheme who takes does: the utility model provides an artifical lift by crane prevents weighing down self-lock device, which comprises an outer shell, spring bolt and pulley, the shell is narrow flat trapezium structure under wide, upper and lower end opening, the spring bolt is triangle platelike structure, the one corner is articulated through the hinge shaft and has cup jointed the torsional spring that can keep the spring bolt rotatory in the articulated shaft of the department in the shell lower left corner department and articulated department, the articulated relative flank of department of spring bolt sets up to the arcwall face structure, be provided with ascending lock tooth on the arcwall face structure, can will penetrate the vertical locking of lifting rope in the shell right side after the spring bolt free rotation, the side sets up two connecting strips of symmetry around the shell upper end, the connecting strip upper end has the pulley through pulley shaft swivelling.
Preferably, the cross section of the arc-shaped surface structure is an arc-shaped groove structure.
Preferably, the mounting frame comprises two connecting plates, one ends of the two connecting plates are symmetrically hinged to the two outer ends of the pulley shaft, and the other ends of the two connecting plates are connected through bolts.
Preferably, the side is provided with the handle on the articulated department of above-mentioned spring bolt, and the handle stretches out shell upper end left side.
The utility model has the advantages that: compared with the prior art, the utility model discloses install and suspend in midair the point of hanging, in the lifting rope penetrated the shell right side, and the round trip pulley, the downward pulling pulley opposite side lifting rope treats the hoist and mount part rebound under the effect of stay cord, and under the torsional spring effect of spring bolt, the automatic reverse locking lifting rope of spring bolt plays and prevents weighing down the effect, when the manual work lifts by crane the handoff, and the locking object that falls is braked fast in the confined distance, suspends article in midair safer, avoids article to drop the safety risk who hurts the people.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1: as shown in fig. 1-4, an artifical lift by crane prevents weighing down self-lock device, which comprises a housing 1, spring bolt 2 and pulley 3, shell 1 is the narrow flat trapezium structure down wide, upper and lower end opening, spring bolt 2 is the triangle platelike structure, one corner articulates in shell 1 on the articulated shaft 4 of lower left corner department and articulated department through articulated shaft 4 and has cup jointed the torsional spring 5 that can keep the rotation of spring bolt 2, 2 articulated department opposite flank of spring bolt sets up to arcwall face structure 6, be provided with up lock tooth on the arcwall face structure 6, can will penetrate the vertical locking of lifting rope in the shell 1 right side after 2 free rotation of spring bolt, shell 1 upper end front and back side sets up two connecting strips 7 of symmetry, connecting strip 7 upper end has pulley 3 through 8 swivelling joint of pulley shaft, be connected with mounting bracket 9 on the pulley 3.
Preferably, the cross section of the arc-shaped surface structure 6 is an arc-shaped groove structure, so that the lifting rope can be attached conveniently, the contact area is increased, and the locking is more reliable.
Preferably, the mounting frame 9 comprises two connecting plates 10, one ends of the two connecting plates 10 are symmetrically hinged to the two outer ends of the pulley shaft 8, and the other ends of the two connecting plates are connected through bolts 11.
Preferably, the side is provided with handle 12 on the articulated department of above-mentioned spring bolt 2, and handle 12 stretches out 1 upper end left side of shell, and the manual selection handle is convenient for give way the spring bolt the space that the lifting rope penetrated, is convenient for install the lifting rope.
The use principle is as follows: in lifting rope 13 penetrated shell 1 right side, and around pulley 3, on installation component's equipment was installed to mounting bracket 9, pulling pulley opposite side lifting rope downwards, treat hoisting component rebound under the effect of stay cord, moreover under the torsional spring effect of spring bolt, the automatic reverse locking lifting rope of spring bolt played and prevented weighing down the effect.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
