Abstract
The invention relates to an escalator hand belt tension adjusting device and belongs to the technical field of escalator manufacturing. A fixed roller disc and a movable roller disk are arc-shaped, rollers are sequentially arranged on the fixed roller disc and the movable roller disc along the direction of the arc, radian of the movable roller disc is less than that of the fixed roller disc, and the movable roller disc is arranged on the outer arc surface of the fixed roller disc. The escalator hand belt tension adjusting device uses a hand belt tension detection device in an escalator for performing coordinate control. At first, a cylinder is at an initial state, along with increase of operation time, under the condition that passengers are many and load is increased, the cylinder pushes the movable roller disc to move downward to tension a hand belt so as to guarantee consistency of operation of the hand belt and stairs. The cylinder is taken back when the load is reduced, and the hand belt springs back.
Description
Technical field
The present invention relates to the hand steered band degree of tension of a kind of staircase control apparatus, belong to technical field of elevator manufacturing.
Background technology
Hand steered band is along with step is mobile in the lump on the staircase, and speed will be consistent with the motion of step.One important leverage of hand steered band 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 step motion inconsistent, in advance or lost motion.The motion of pin and hand the inconsistent personnel of causing fall down.
Summary of the invention
The present invention is directed to above-mentioned deficiency the hand steered band degree of tension of a kind of staircase control apparatus is provided.
The present invention adopts following technical scheme:
The hand steered band degree of tension of a kind of staircase of the present invention control apparatus comprises and decides roller disk, action roller dish, roller; Decide roller disk and action roller dish circular arc, and decide roller disk and action roller dish upper edge circular arc direction is arranged in order the arrangement roller; The radian of action roller dish is less than deciding roller disk; The action roller dish is arranged on the extrados of deciding roller disk.
The hand steered band degree of tension of staircase of the present invention control apparatus also comprises 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 deciding roller disk; Arrange spring between action roller dish and the spring.
The hand steered band degree of tension of staircase of the present invention control apparatus, described base arrange that the spring place arranges groove.
Beneficial effect
The hand steered band degree of tension of staircase provided by the invention control apparatus utilizes the hand steered band tensioning detecting device in the staircase, cooperates regulation and control.Originally cylinder initial condition, along with the increase of time of run, under 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 bullet of taking back of withdrawal cylinder when load reduces.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is described in more detail below in conjunction with accompanying drawing:
As described in Figure: the hand steered band degree of tension of a kind of staircase control apparatus comprises and decides roller disk 1, action roller dish 2, roller 3, cylinder 4, spring 5, outer cover 6, base 7; Decide roller disk 1 and action roller dish 2 circular arcs, and decide roller disk 1 and be arranged in order arrangement roller 3 with action roller dish 2 upper edge circular arc directions; The radian of action roller dish 2 is less than deciding roller disk 1; Action roller dish 2 is arranged on the extrados of deciding roller disk 1.
The hand steered band degree of tension of staircase provided by the invention control apparatus utilizes the hand steered band tensioning detecting device in the staircase, cooperates 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, under 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 bullet of taking back of withdrawal cylinder when load reduces.
