Description
Technical field
The utility model belongs to component of machine, has been specifically related to a kind of leading block with hatch lock.
Background technique
Leading block is widely used in cable crane and cableway transportation system.Usually, when a funicular system is designed to install, the funicular system that just formation one is closed.If now for increasing new leading block (or tension pulley block) in system, then require that the pulley increased newly should have opening function, closed funicular system work can be entered.Have the leading block of opening function, the cable transporting something containerized material funicular system for forest zone wood producing is particularly important.Because forest zone operating mode is complicated, for the cable logging system that has designed, after installing, often according to actual needs, by additional leading block, funicular system must be adjusted temporarily, or tensioning is carried out to system, or change the trend of cable.For this reason, people have developed the pulley that some have opening function, as Chinese Patent Application No. a kind of snatch block disclosed in 201220300389.8, comprise suspension ring, mainboard and pulley, suspension ring are connected with side guard plate one and side guard plate two by latch shaft, side guard plate one is connected with pulley by main shaft with side guard plate two, and side guard plate one is connected with movable mainboard two and movable mainboard one with main shaft respectively by latch shaft, and movable mainboard one is connected with movable mainboard two by pin; Described side guard plate two is connected with mainboard with main shaft respectively by latch shaft, and mainboard is connected by high strength hex head bolt with movable mainboard one.The pulley of technique scheme has possessed the function of opening, but also there is following deficiency: as many in complicated structure, Component, not easily manufacture, especially can not realize pure manual opening-closing lock catch, the instruments such as spanner must be used can to open or close snap close, use inconvenience etc.
Summary of the invention
The purpose of this utility model is the leading block with opening function providing a kind of structure simple, practical.
To achieve these goals, the utility model have employed following technological scheme:
With a leading block for hatch lock, comprise pulley; Left auricle and auris dextra sheet is separately installed with at the two ends of the pulley axle of pulley; Wherein, U-lock button is also comprised; One end of described U-lock button and the upper end thereof of auris dextra sheet; The other end of described U-lock button is provided with lockhole II; The upper end of described left auricle is provided with the groove matched with U-lock button size, and the both sides of groove are respectively equipped with lockhole I, lockhole III; When the leading block of this band hatch lock is in closed state, bolt assembly or screw thread bearing pin is adopted U-lock button and left auricle to be linked together through lockhole I, lockhole II, lockhole III successively.
Further illustrate as of the present utility model, when adopting screw thread bearing pin U-lock button and left auricle to be linked together, described lockhole I and lockhole II are unthreaded hole; Described lockhole III is interior threaded hole; When adopting bolt assembly U-lock button and left auricle to be linked together, described lockhole I, lockhole II and lockhole III are unthreaded hole.
In the utility model, when adopting screw thread bearing pin, lockhole I and lockhole II are unthreaded hole, lockhole III is interior threaded hole (being equivalent to the function of nut), are matched like this by the internal thread of lockhole III with the outside thread of screw thread bearing pin, make U-lock button form reliable connection with left auricle.In the utility model, when adopting bolt assembly, lockhole I, lockhole II, lockhole III can be unthreaded hole; Lockhole III does not need to be set to interior threaded hole specially, can certainly be set to interior threaded hole.
Further illustrate as of the present utility model, the upper end of described auris dextra sheet and one end of U-lock button are undertaken hinged by hinge.
The leading block working principle of band hatch lock of the present utility model:
Time initial, the hatch lock of leading block is in closed state, and cable can not free in and out pulley, when needs cable turnover pulley, the head (having one end of flange) of screw thread bearing pin is pinched with hand thumb and forefinger, by counterclockwise rotating, screw thread bearing pin being separated with being threaded of left auricle, taking out screw thread bearing pin, U-lock button is upwards pulled, turn to horizontal position around hinge, make U-lock buckle in open state, now cable laterally can free in and out pulley.Cable turnover is complete, is closed by U-shaped snap close by above-mentioned reverse procedure, manually screws in threaded shaft locking, and make pulley hatch lock recover closed state, cable can not free in and out pulley.
Advantage of the present utility model:
1, for installing ready closed funicular system, the leading block of band hatch lock of the present utility model can manually be unblanked at any time, laterally enters or exits funicular system, and need not disassembly system.
2, the leading block of band hatch lock of the present utility model, the opening of its U-lock button adopts hand thread pinned connection, and it is unblanked and latching process need not use instrument, manually can complete.
3, the leading block of band hatch lock of the present utility model, structure is simple, easy to use, be easy to manufacturing, economical and practical.
