Abstract
The utility model relates to a tension degree adjusting device for a hand holding belt of an escalator, and belongs to the technical field of escalator manufacturing. A fixed idler wheel plate and a movable idler wheel plate are respectively in an arc shape, idler wheels are sequentially arrayed on the fixed idler wheel plate and the movable idler wheel plate in the arc direction, the radian of the movable idler wheel plate is smaller than the radian of the fixed idler wheel plate, and the movable idler wheel plate is arranged on the outer arc surface of the fixed idler wheel plate. The tension degree adjusting device for the hand holding belt of the escalator conducts adjustment and control in cooperation with a hand holding belt tension detection device in the escalator. At first, an air cylinder is in the initial state; when the running time of the hand holding belt is increased, the number of passengers is increased and load is increased, the air cylinder pushes the movable idler wheel plate to move downwards to strain the hand holding belt, and therefore synchronicity of the running of the hand holding belt and the running stairs is ensured; the air cylinder is retracted when the load is decreased, and the hand holding belt is rebounded.
Description
Technical field
The utility model relates to the hand steered band degree of tension of a kind of staircase control apparatus, belongs to technical field of elevator manufacturing.
Background technology
On staircase, hand steered band is along with step moves in the lump, and speed will be consistent with the motion of step.Hand steered one important leverage with thing protection personal security.Hand steeredly be with a kind of rubber product, can cause hand steered band to damage long-term after using the box wearing and tearing.At present, the most incident situation is the stretching, extension of hand steered band, the length of the hand steered band that stretches, cause with the step motion inconsistent, in advance or lost motion.The motion of pin and hand the inconsistent personnel of causing fall down.
The utility model content
The utility model provides the hand steered band degree of tension of a kind of staircase control apparatus for above-mentioned deficiency.
The utility model adopts following technical scheme:
The hand steered band degree of tension of a kind of staircase described in the utility model control apparatus, comprise and determine roller disk, action roller dish, roller; Determine roller disk and action roller dish circular arc, and determine along the circular arc direction, to be arranged in order the arrangement roller on roller disk and action roller dish; The radian of action roller dish is less than determines roller disk; The action roller dish is arranged on the extrados of determining roller disk.
The hand steered band degree of tension of staircase described in the utility model control apparatus, also comprise cylinder, spring, outer cover, base; Described cylinder is connected with an end of action roller dish; Outer cover parcel action roller dish; Base is arranged in outer cover and an end of determining roller disk; Between action roller dish and spring, arrange spring.
The hand steered band degree of tension of staircase described in the utility model control apparatus, described base arrange that the spring place arranges groove.
Beneficial effect
The hand steered band degree of tension of the staircase that the utility model provides control apparatus, utilize the hand steered band tensioning detecting device in staircase, coordinates regulation and control.Originally cylinder initial condition, along with the increase of time of run, in the situation that the more load of occupant strengthens, cylinder advances the action roller dish to move down the hand steered band of tension, has guaranteed the conformability of hand steered band and step operation, the hand steered band resilience of withdrawal cylinder when load reduces.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As described in Figure: the hand steered band degree of tension of a kind of staircase control apparatus comprises and determines roller disk 1, action roller dish 2, roller 3, cylinder 4, spring 5, outer cover 6, base 7; Determine roller disk 1 and action roller dish 2 circular arcs, and determine along the circular arc direction, to be arranged in order and to arrange roller 3 on roller disk 1 and action roller dish 2; The radian of action roller dish 2 is less than determines roller disk 1; Action roller dish 2 is arranged on the extrados of determining roller disk 1.
Cylinder 4 is connected with an end of action roller dish 2; Outer cover 6 parcel action roller dishes 2; Base 7 is arranged in outer cover 6 and an end of determining roller disk 1; Between action roller dish 2 and spring 5, arrange spring 5.Base 7 arranges that spring 5 places arrange groove.
The hand steered band degree of tension of the staircase that the utility model provides control apparatus, utilize the hand steered band tensioning detecting device in staircase, coordinates regulation and control.The control module of cylinder is connected with the tensioning detecting device.
Originally cylinder initial condition, along with the increase of time of run, in the situation that the more load of occupant strengthens, cylinder advances the action roller dish to move down the hand steered band of tension, has guaranteed the conformability of hand steered band and step operation, the hand steered band resilience of withdrawal cylinder when load reduces.
