Abstract

The invention discloses a vertical shaft hoisted cage differential synchronizer, and belongs to the technical field of construction. The vertical shaft hoisted cage differential synchronizer comprises a movable pulley block and a balancing weight, and further comprises a rail, an upper limiter, a lower limiter, a vice rope winch abrupt stop switch, an upper beam and a lower beam, wherein the upper beam and the lower beam are installed on the right side of a portable frame and located between a vertical post and an inclined support; the rail is installed between the upper beam and the lower beam; the balancing weight is installed on the rail; the upper limiter and the lower limiter are installed on the vertical post; and a vice rope is connected to a vice rope winch through a left fixed pulley, the movable pulley block and a right fixed pulley. According to the vertical shaft hoisted cage differential synchronizer, the risk that a hoisted cage falls off is lowered, safety risks of working staff are reduced at the same time, and working efficiency is improved; and the problem that a main rope and the vice rope are inconsistent in speed is solved, and the safe and fast vertical conveying of vertical shaft construction materials is achieved.

Description

Vertical shaft cage differential synchro

Technical field

The present invention relates to a kind of vertical transferring apparatus, especially the vertical shaft cage, belong to technical field of construction.

Background technology

At present,, in the Hydraulic and Hydro-Power Engineering To Construction of Silo, adopt single wire rope lifting reinforcing bar cage to transport material, construction safety risk is very big, and workmen's life security is caused great threat; But when adopting duplex type lifting reinforcing bar cage, need to solve the two inconsistent problems of rope running velocity.

Summary of the invention

For the problems referred to above, the invention provides a kind of differential synchro that coordinates the duplex type cage to use.

The technical solution adopted for the present invention to solve the technical problems is: vertical shaft cage differential synchro comprises running block and clump weight; Also comprise track, upper limit device, lower retainer, secondary rope winch emergency stop switch, upper beam and underbeam; Upper beam and underbeam are arranged on the portal frame right side and between column and diagonal ligament; Track is arranged between upper beam and underbeam; Clump weight is installed on track; Upper limit device, lower retainer are arranged on column; Secondary rope arrives secondary rope winch through left fixed pulley, running block, right fixed pulley.

The invention has the beneficial effects as follows, reduced the risk that cage falls, also reduced staff's security risk simultaneously, improved work efficiency; Solve the inconsistent problem of major and minor rope speed, realized the top-down safety of To Construction of Silo material, fast transportation.

The specific embodiment

The present invention is further described below in conjunction with embodiment.

Referring to Fig. 1,2, vertical shaft cage differential synchro comprises running block 1 and clump weight 2; Also comprise track 3, upper limit device 4, lower retainer 5, secondary rope winch emergency stop switch 6, upper beam 7 and underbeam 16; Upper beam 7 and underbeam 16 are arranged on portal frame 11 right sides and between column 8 and diagonal ligament 9; Track 3 is arranged between upper beam 7 and underbeam 16; Clump weight 2 is installed on track 3; Upper limit device 4, lower retainer 5 are arranged on column 8; Secondary rope 15 arrives secondary rope winch 21 through left fixed pulley 14, running block 1, right fixed pulley 22.

Main rope 12 uses 10 tons of main rope winchs 13, and main rope 12 is connected by wire clips with cage 10 by main rope fixed pulley group, left fixed pulley 14.Secondary rope 15 uses 10 tons of secondary rope winchs 21 to be fixed in ground.

Increase guide rope 17 in main rope 12 1 sides, to stablize cage 10, prevent its horizontally rotating or playing pendulum in lifting, decline process.Guide rope 17 uses 5 tons of guide rope winchs 18, and guide rope 17 passes two steelframe arms 19 on cage 10 through guide rope fixed pulley group, and guide rope 17 terminals are connected with guide rope clump weight 20 by snap ring.First guide steel wire rope 17 is put down before cage 10 descends, the rear cage 10 that comes to a complete stop can move.

The differential synchro is the use of regulating major and minor rope speed, and clump weight 2 slides up and down along two siding tracks 3.Operation between upper limit device 4 and lower retainer 5, normal range ability is 1 meter.

Main rope 12 transports material with the common traction cage of secondary rope 15 in vertical shaft, when major and minor rope speed was inconsistent, the differential synchro was started working.

Main rope winch 13 and secondary rope winch 21 can be worked simultaneously, also can work independently, and two winchs all are equipped with emergency stop switch.

Initial condition differential synchro is positioned at upper limit device 4 places, if major and minor rope running velocity is consistent, the differential synchro is stopped at upper limit device 4 places, does not work.

When main rope 12 excessive velocities, secondary rope 15 is main head-rope, and the differential synchro stops main rope winch this moment in the 4 places warning of upper limit device, regulates secondary rope running velocity, makes it recovery consistent.

Cross when slow when main rope 12 speed, the differential synchro slides downwards along track 3, and in the process of sliding, consistent if major and minor rope running velocity is regulated, major and minor winch continues operation; If the differential synchro moves to lower retainer 5 positions, major and minor rope running velocity is still inconsistent, and the differential synchro is reported to the police, and stops secondary rope winch this moment, regulates main rope running velocity, recover unanimously after the major and minor rope winch of synchronized operation again.
