Abstract
The invention discloses a guide pulley with an open lock. The guide pulley comprises a pulley body and further comprises a U-shaped lock catch, wherein a left ear piece and a right ear piece are respectively mounted at the two ends of the pulley spindle of the pulley body; one end of the U-shaped lock catch is hinged to the upper end of the right ear piece; a lockhole II is formed in the other end of the U-shaped lock catch; a groove matched with the U-shaped lock catch in size is formed in the upper end of the left ear piece; a lockhole I and a lockhole III are respectively formed in the two sides of the groove; when the guide pulley with the open lock is in a closed state, a bolt assembly or a threaded pin shaft sequentially penetrates through the lockhole I, the lockhole II and the lockhole III, so as to connect the U-shaped lock catch with the left ear piece. The guide pulley provided by the invention is simple in structure, easy to process and manufacture, economic and practical; the lock can be manually opened at any time, so that the guide pulley can transversely enter or retreat from a cable system and the disassembly of the cable system is not required.
Description
Technical field
The invention belongs to component of machine, be 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, just form a closed funicular system.In system, increase new leading block (or tension pulley block) if now want, require newly-increased pulley should there is opening function, can enter closed funicular system work.There is the leading block of opening function, particularly important for the cable transporting something containerized material funicular system of forest zone timber production use.Due to forest zone operating mode complexity, for a cable logging system having designed, after installing, often must according to actual needs, by additional leading block, funicular system be adjusted temporarily, or system is carried out to tensioning, or change the trend of cable.For this reason, people have researched and developed some and have had the pulley of opening function, if Chinese Patent Application No. is 201220300389.8 disclosed a kind of snatch blocks, 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 by latch shaft respectively, and movable mainboard one is connected with movable mainboard two by pin; Described side guard plate two is connected with mainboard with main shaft by latch shaft respectively, 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 exist following deficiency: as complicated structure, many, the difficult manufactures of Component, especially can not realize pure manual opening-closing lock catch, must use the instruments such as spanner can open or close snap close, use inconvenience etc.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, practical leading block with opening function.
To achieve these goals, the present invention has adopted following technological scheme:
With a leading block for hatch lock, comprise pulley; Be separately installed with left auricle and auris dextra sheet at the two ends of the pulley axle of pulley; Wherein, also comprise U-lock button; The upper end of one end of described U-lock button and auris dextra sheet is hinged; 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 matching with U-lock button size, and the both sides of groove are respectively equipped with lockhole I, lockhole III; When this leading block with hatch lock is during in closed state, adopt bolt assembly or screw thread bearing pin through lockhole I, lockhole II, lockhole III, U-lock button and left auricle to be linked together successively.
Further illustrate as of the present invention, in the time adopting screw thread bearing pin that U-lock button and left auricle are linked together, described lockhole I and lockhole II are unthreaded hole; Described lockhole III is interior threaded hole; In the time adopting bolt assembly that U-lock button and left auricle are linked together, described lockhole I, lockhole II and lockhole III are unthreaded hole.
In the present invention, while 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), match 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 present invention, while adopting bolt assembly, lockhole I, lockhole II, lockhole III can be unthreaded hole; Lockhole III does not need to be set to specially interior threaded hole, can certainly be made as interior threaded hole.
Further illustrate as of the present invention, one end of the upper end of described auris dextra sheet and U-lock button is undertaken hinged by hinge.
Leading block working principle with hatch lock of the present invention:
When initial, the hatch lock of leading block is in closed state, and cable can not free in and out pulley, in the time of needs cable turnover pulley, pinch the head (having one end of flange) of screw thread bearing pin with hand thumb and forefinger, by counterclockwise rotation, screw thread bearing pin is separated with being threaded of left auricle, take 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 can laterally free in and out pulley.Cable turnover is complete, by above-mentioned reverse procedure, U-shaped snap close is closed, and manually screws in threaded shaft locking, makes pulley hatch lock recover closed state, and cable can not free in and out pulley.
Advantage of the present invention:
1, for ready closed funicular system is installed, the leading block with hatch lock of the present invention can manually be unblanked at any time, laterally enters or exit funicular system, and need not disassembly system.
2, the leading block with hatch lock of the present invention, the opening of its U-lock button adopts hand thread bearing pin to connect, and it is unblanked and locking process need not be used instrument, manually can complete.
3, the leading block with hatch lock of the present invention, simple in structure, easy to use, be easy to manufacturing, economical and practical.
