Embodiment 1

[0019] Example 1, Figure 8 It is a schematic diagram of Embodiment 1, and the drawing shows the appearance of the side of the lifting equipment. The horizontal electromagnetic drive safety brake device is installed on the top of the rack-and-pinion lifting equipment, temporarily in a free position, and the lifting equipment is ready to run or is running In the situation, Figure 9 It is a schematic diagram of the situation that the horizontal electromagnetic promotion safety braking device of embodiment 1 brakes the lifting equipment, (the front figure 1 , figure 2 , image 3 , Figure 4 , Figure 6 , Figure 7 The left and right mentioned are viewed from the inside of the lifting device to the side of the lifting device. Figure 8 , Figure 9 It is viewed from the outside to the side of the lifting equipment, so the left and right directions are just in reverse), and the horizontal electromagnetic push safety brake device is used for the description of the components...

Embodiment 2

[0020] Example 2, Figure 8 , Figure 9 It is also a schematic diagram of embodiment 2, which shows a kind of elevator installed with the horizontal electromagnetic propulsion safety braking device of the present invention. See Figure 1-7 As shown, and described in [0004], [0005], [0006], and [0007], the working principle is the same as that described in [0019].

Abstract

The invention discloses a horizontal electromagnetic pushing safety braking device for a gear and rack lifting device. The horizontal electromagnetic pushing safety braking device comprises a bearing part, a rail assembly, a movable rack, a limiting mechanism for the movable rack, an operation mechanism for the movable rack, a control device for the operation mechanism for the movable rack, and a manual unlocking mechanism. The top of the movable rack makes direct contact with a main bearing structure of a lifting device lift car after entering a braking state for bearing or makes contact with the main bearing structure through a middle transition bearing part for bearing. The operation mechanism for the movable rack configured in the horizontal direction operates the movable rack to horizontally move on a rail hole or stay and keep at a braking position engaged with a drive rack of the lifting device or a free position completely disengaged from the drive rack of the lifting device and having a certain gap with the drive rack. An electromagnetic pusher is adopted so that the dead load of the device can be better reduced; and the beneficial effects that the dead load is reduced, effective space is saved, the flat layer precision is obviously improved, and the safety protection braking quality is obviously improved are achieved.

Description

technical field [0001] The invention relates to the field of safety braking devices for lifting equipment, in particular to a horizontal electromagnetically driven safety braking device for rack and pinion lifting equipment. Background technique [0002] The existing safety braking device of rack and pinion lifting equipment is realized by stopping the driving gear from rotating through various methods; but if there is a problem with the driving gear, such as tooth damage, reliable braking cannot be guaranteed even if the gear does not rotate ;In order to ensure safety, the rack and pinion lifting equipment must be equipped with a reliable safety brake device that can deal with problems including driving gears and similar safety problems. Contents of the invention [0003] The object of the present invention is to provide a reliable safety braking device capable of dealing with problems involving driving gears and similar safety problems. [0004] figure 1 It is a struct...
