Abstract
The utility model discloses a mechanical braking device for escalators, which comprises a bracket (1) and a driving main spindle (2) of the existing escalator. The bracket (1) is provided with an electromagnet (3) which is connected with a pawl device (5) positioned on the bracket (1) by a long screw (4); the pawl device (5) is provided with a pawl (6); the driving main spindle (2) is provided with a ratchet wheel (7); a ratchet (8) is arranged on the ratchet wheel (7) and in contact with the pawl (6). When the escalator runs normally, the electromagnet is powered on and then drives the long screw to withdraw the pawl in the pawl device without affecting the normal rotation of the main spindle. But when the escalator is in fault, the electromagnet is powered off, the pawl is ejected from a pawl holder by a spring to stop the ratchet wheel from rotating so that the driving main spindle connected with the ratchet wheel cannot rotate any longer, thereby preventing accidents caused by backward slip when the escalator has a fault.
Description
Technical field
The utility model relates to the mechanical brake device of a kind of brake equipment, particularly a kind of escalator.
Background technology
Escalator is continuous and big flow performance with it, firmly gets the market, and crowd's flows such as airport are than large user's favor.But because various faults make when safety return circuit destroys that during particularly owing to the dragging chain fracture, staircase is under the weight effect of personnel and article on deadweight and the step, it is sliding to cause the back fast at escalator; If do not slide after having a cover actv. mechanical device to stop staircase, escalator might directly threaten life with the danger close that becomes.
The utility model content
The purpose of this utility model is, a kind of mechanical brake device of escalator is provided, to prevent when staircase breaks down sliding causing the accident after staircase produces.
The technical solution of the utility model: a kind of mechanical brake device of escalator comprises support and drive shaft; Be provided with electromagnet on support, electromagnet is connected with pawl device on being located at support through long bolt, and pawl device is provided with ratchet; Be provided with ratchet on drive shaft, ratchet is provided with ratchet, and ratchet contacts with ratchet.
In the mechanical brake device of above-mentioned escalator, described pawl device comprises and support bonded assembly base plate; Base plate one end is connected with spring bracket, and the base plate bottom is connected with ratchet holder; Be provided with ratchet in the ratchet holder, ratchet is connected with the screw thread fork arm with connecting plate through pawl axis; Be rotary with the long bolt that passes spring bracket on the screw thread fork arm, between screw thread fork arm and spring bracket, be provided with spring.
In the mechanical brake device of aforesaid escalator, the cross section of described pawl axis and ratchet junction is a rectangle.
In the mechanical brake device of aforesaid escalator, described spring end is provided with spring perch.
Compared with prior art, when the utility model normally moves at escalator, the electromagnet energising, electromagnet promotes long bolt, makes that the ratchet in the pawl device is regained, and can not influence main shaft and normally rotate, and this device does not influence spindle operation.But at escalator various faults appear, when rupturing as dragging chain, the electromagnet outage, ratchet is under the effect of spring, eject ratchet holder, stop the ratchet rotation, because the ratchet stall, so can not be rotated further with ratchet bonded assembly drive shaft, can prevent sliding the causing the accident in staircase generation back when staircase breaks down.
Description of drawings

Being labeled as among the figure: 1-support, 2-drive shaft, 3-electromagnet, 4-long bolt, 5-pawl device, 6-ratchet, the 7-ratchet, 8-ratchet, 9-base plate, 10-spring bracket, 11-ratchet holder, the 12-pawl axis, 13-connecting plate, 14-screw thread fork arm, 15-spring, 16-spring perch.
The specific embodiment
Be described in further detail below in conjunction with the mechanical brake device of drawings and Examples a kind of escalator of the present utility model, but not as the foundation of the utility model being done any restriction.
Embodiment.The mechanical brake device of a kind of escalator of the present utility model, as shown in Figure 1.Comprise support 1 and drive shaft 2 on the existing escalator; Be provided with electromagnet 3 on support 1, electromagnet 3 is connected with pawl device 5 on being located at support 1 through long bolt 4, and pawl device 5 is provided with ratchet 6; Be provided with ratchet 7 on drive shaft 2, ratchet 7 is provided with ratchet 8, and ratchet 8 contacts with ratchet 6.Described pawl device 5 comprises and support 1 bonded assembly base plate 9; Base plate 9 one ends are connected with spring bracket 10, and base plate 9 bottoms are connected with ratchet holder 11; Be provided with ratchet 6 in the ratchet holder 11, ratchet 6 is connected with screw thread fork arm 14 with connecting plate 13 through pawl axis 12; Pawl axis 12 is a rectangle with the cross section of ratchet 6 junctions.Be rotary with the long bolt 6 that passes spring bracket 10 on the screw thread fork arm 14, between screw thread fork arm 14 and spring bracket 10, be provided with spring 15.Spring 15 ends are provided with spring perch 16.
Principle of work of the present utility model: when the utility model normally moves at escalator, the electromagnet energising, electromagnet promotes long bolt, makes that the ratchet in the pawl device is regained, and can not influence main shaft and normally rotate, and this device does not influence spindle operation.But at escalator various faults appear, when rupturing as dragging chain, the electromagnet outage, ratchet is under the effect of spring, eject ratchet holder, stop the ratchet rotation, because the ratchet stall, so can not be rotated further with ratchet bonded assembly drive shaft, can prevent sliding the causing the accident in staircase generation back when staircase breaks down.
