Abstract

The utility model discloses a rope downslide controller, the controller comprises a brake disc, a movable handle, a fixed handle, a front cover board, a brake pad, a bearing base, a driving wheel, a back cover board and a brake handle, the down speed can be adjusted according to the needs, the movable handle is hold tightly when the down speed is slow, the brake pad is pushed to move forward by beads which are arranged in a wedge-shaped groove of the brake disc, the gap between the driving wheel and a brake drum is narrowed, the rope friction between the driving wheel and the brake drum is increased, therefore, the down speed is slow, the movable handle is loosed, the brake disc is reset by a reset spring, further, the gap between the driving wheel and the brake drum is returned and the down speed is increased. When in high-altitude operation, the brake handle is rotated to make a support rod be adjusted to an upper dead point from a movable pulley to position the controller at a position. The utility model has compact structure, safety, reliability, convenient and flexible use, which can slide down from a high building conveniently and rapidly, in addition, the speed can be controlled arbitrarily, and the utility model can be stayed at any position at any time.

Description

Rope downslide controller

Technical field

The utility model relates to the controller that a kind of high-rise building life saving or work high above the ground are used.

Background technology

At present, the high buildings and large mansions of various places are acquisition approval and rising like the mushrooms after rain, continuous increase along with high building, the high-rise building fire prevention, lifesaving has become an important problem with operation, the breaking out of fire of high building bottom, can only lean on fire department to rescue the people with high-rise stair, but the height of stair is limited, and the speed of rescuing the people is also slow, and this way does not fit into current needs, and the long cloth bag that also has the hard cloth making of a kind of usefulness is as brucker survival capsule, one of its cloth bag is fixed on upstairs, the other end is from upstairs throwing away on the ground, and the people slides from cloth bag, and it is long more to implement its cloth bag of lifesaving in this way, volume is just big more, and the scope that can only accomplish three or four floors, be subjected to the restriction of story height restriction and the length weight of cloth bag own, also be difficult to play a role.

The utility model content

The purpose of this utility model is to provide a kind of and can be conveniently slides from high level upstairs, and speed can be controlled arbitrarily, can also fixedly stop at the rope downslide controller of optional position.

Technical solution of the present utility model is: rope downslide controller is made up of brake disc, flexible handle, fixed handle, front shroud, brake block, bearing block, driving wheel, back shroud and brake handle, connect by steady pin respectively between front shroud, bearing block and the back shroud, flexible handle is fixed on the brake disc, fixed handle is fixed on the front shroud, back-moving spring one end is arranged on the fixed handle, and the other end is arranged on the brake disc; Brake disc is connected with front shroud by bearing pin, bearing pin is supported by bearing, one location projection is arranged in the middle of the front shroud, have through hole on the projection, trace is set in the through hole, the trace rear end is provided with groove and matches with ball in the inboard wedge-shaped slot of brake disc, and the cylindrical groove with the brake block rear end of trace front end matches, and is with back-moving spring on the trace; Bearing block is movably arranged in the back shroud, driving wheel is arranged in the bearing block by axle and bearing, wheel shaft is arranged in the elongated slot of bearing block both sides, semi-circular braking hub is set in the back shroud, braking hub and driving wheel matched in clearance, braking hub two ends are provided with follow-up pulley, and the interior brake(-holder) block of follow-up pulley and bearing block grooves on two sides contacts; Back brake handle is made up of taper knob, handle, and taper knob is screwed onto on the Handle axis, and Handle axis and back shroud are spirally connected, and the taper knob front end is provided with the adjustment plate of pole, and pole is provided with spring, and the pole front end contacts with the wheel shaft that can adjust follow-up pulley.

The utility model can be clamped in rope between braking hub and the driving wheel, two ends are passed between follow-up pulley and brake(-holder) block respectively, promote brake block and adjust driving wheel and the gap of braking between the hub by adjusting fixed handle and flexible handle, controller is glided along rope, realize high building decline function, and can control the speed of decline, this apparatus structure compactness, safe and reliable, characteristics such as flexibly easy to use, and can arbitrarily rest on aerial optional position.

Fig. 3 is the magnifying state of the cutaway view of the utility model rope downslide controller right view.

The specific embodiment

The utility model rope downslide controller, form by brake disc 4, flexible handle 1, fixed handle 2, front shroud 8, brake block 9, bearing block, driving wheel 12, back shroud 14 and brake handle 15, be connected by steady pin 18 respectively between front shroud, bearing block and the back shroud.Flexible handle 1 is fixed on the brake disc 4, and fixed handle 2 is fixed on the front shroud, and back-moving spring 3 one ends are arranged on the fixed handle, and the other end is arranged on the brake disc, and after brake disc rotated, back-moving spring resetted it.Bearing pin 3 is set in the brake disc to be connected with front shroud, bearing pin is installed on the bearing of brake disc, and the brake disc inboard is symmetrical arranged two wedge-shaped slots, is equipped with ball 5 in the groove, locating convex block is set in the middle of the front shroud, projection is provided with through hole, and trace 7 passes through hole, the groove that the trace rear end is provided with, match with ball in the brake disc 5, trace front end front end is cylindrical, matches with the groove of brake block 9 rear ends, is with back-moving spring 6 on the trace; The brake block front end is provided with driving wheel 12, driving wheel is movably arranged in the bearing block by axle and bearing, the bearing block both sides are provided with an elongated slot, wheel shaft can elongated slot in slide, the bearing block two ends are provided with groove, be provided with brake(-holder) block 10 in the groove, the braking hub 13 be semi-circular, be screwed onto in the back shroud 14, and with the driving wheel matched in clearance, braking hub two ends are provided with follow-up pulley 11,17, follow-up pulley is installed in the back shroud two ends, and is corresponding with bearing block inside brake sheet, and one of them follow-up pulley is a fixed block 11, another is for can adjust follow-up pulley 17, and pulley spindle is arranged in the elongated slot; Back brake handle 15 is made up of taper knob, handle, and taper knob is screwed onto on the Handle axis, and Handle axis and back shroud are spirally connected, the taper knob front end is provided with the adjustment plate 19 of pole 20, pole is provided with spring 21, and the pole front end is coupling and touches with adjusting follow-up pulley, and the back shroud lower end is provided with retainer ring 22.
