Invention description (2) The stretching system such as (2) is sometimes called " step tenon tape stretching Ito ". At this time, a typical escalator ladder belt stretching system includes a compression spring frame on each side of the conveying frame, or is operatively combined with a hinge on each side. The tensile force is mechanical in nature, such as a threaded rod connected to a compression spring. In order to equalize the stretching force of the two opposite sides of the conveyor *, that is, to quantify the respective stretching force of each side key, tape measure or ruler measurement is used to estimate the setting of the stretching force. This setting is actually close to the value, and the best one can be affected by a certain change, such as the shrinkage spring rate, and it is susceptible to other adjustment errors due to consumption and maintenance errors. The present invention is directed to providing a liquid tensioning system and designing M to automatically equalize the tension of the chains on opposite sides of the conveyor or the elevator. SUMMARY OF THE INVENTION: Therefore, the object of the present invention is to provide a novel and improved stretching system for the steering track formation of passenger conveyors.

When this pedal moves in the direction of the tendon (40), this assembly There are a pair of front support rollers (36) M and drag support rollers (38). Fig. 2 only shows a description of the ladder ladder M to avoid disturbing. The steering track assembly (32) on each side includes an outer track (42) and (44) and the support roller (36) moves between the two tracks. This track is roughly semi-circular, so the inner rail (42) supports the roller (36) while the upper rail (44) provides a pressing device for the roller while traveling on the upper part of the rail. A second pair is provided for half-groove-shaped tracks (46) and (48) by using M-guided drag wheels (38) to bypass the steering zone. Also: when buried in the upper part of the track, the inner rail (46) supports the drag roller (38) and the outer rail (48) provides a pressing device for the drag roller. Of course, in one of the following lines, the function of supporting and tightening the orbit is reversed. Refer to circle 3 and circle 1, the steering track assembly shown is extremely detailed, including the aforementioned tracks (42) (44) and (46) (48) on each side of the conveyor.

This skateboard extends beyond the inner edge (70) of the base support plate (50) and is configured between three top rollers (72) and three bottom rollers (74) to walk on the fixed main frame ( 12). Therefore, the skateboard (62) can be moved between the rollers (72) and (74) in the direction of the double-headed arrow (76) to drive the steering track sub-assembly (32a) on the double head (34) Movement in the direction of a block. The shape of a push block K angle beam frame (78) is fixed to the fixed main frame (12) by bolts or other suitable fastening devices (80). The push block is placed on The upper side of the skateboard (6 2) is separated from its inner surface.

The present invention expects a hydraulic key to stretch The system is operably combined between the steering track sub-assembly i32a) and the fixed main frame (12), so that the tensile force on the ladder keys on the opposite sides of the _ conveyor is equal on each side of the escalator system . Still refer to 圔 3, the type of a hydraulic stretching device, cylinder and piston device, which is generally indicated by the code (80), and is alternately connected to each steering track sub-assembly (32a) on each supply side of the escalator and Fixed between the main frame (12). Each stretching device includes a cylinder (84) mounted on the slide plate (62) by a bracket (86). A piston (88) extends from the inner terminal of the cylinder (84) and can be fixed to the fixed main frame (12) the combination of the push block (78). Therefore, when applying pressure fluid to the cylinder (84), the piston (88) will abut the push block (78) in the direction of the arrow (90). Move, in turn, the push block moves to the track sub-assembly (32a) back main frame (12). The Central Standards Bureau of the Ministry of Economic Affairs only the consumer cooperative Innu circle 4 shows one end of the hydraulic stretching system.

Therefore, the pressure in the cylinder is kept equal, so that the piston pushes the push block The power of (78) is also equal. The piston and cylinder device itself should be installed substantially parallel to each other * that is, in a common plane to ensure the precise application of equal force in the push block (78). The pressure device (98) provides both the iliac device and the pressure or stretching adjustment. The stretching force on the stepped rope is adjusted by controlling the inlet pressure of the pressure accumulator. The inlet pressure of the pressure accumulator can be controlled by one The pressure gauge (106) monitoring is easy to visually inspect. Of course, the pressure monitoring of the accumulator can be monitored by a pressure transducer or Kang The escalator is controlled by electronic control. This hydraulic system, the emergency stop can be consumed by pressure (that is, the weakening of the tensile force of the key), the fluctuation of the force, the direction of flow or any such sister Triggered by any combination, such as street strikes or destruction of the steering track secondary formation or other abnormal operation conditions. Slow street vibration absorption may also use simple holes or flow control «can be operated with hydraulic pressure This is achieved by a combination of devices. All these advantages are provided by the hydraulic stretching system of the present invention, otherwise, the mechanical stretching system available before M will be impossible and impractical. To those who understand, even without ignoring the spirit or central characteristics of the present invention, other clear forms can also be used as examples. Therefore, this example and practical examples are regarded as the description of each target point without the meaning of restriction, so the present invention will not be limited by the details given herein. -10- The size of this paper is in use _ National «quasi (CNS) A 4 specifications (210x297 public 81. 7. 20.000 < k (ll) (please read the backing notes first # 巩 写 人 装.
