Problems solved by technology

[0002] Improving the effective capacity and saving energy is a task that needs continuous efforts for the rack and pinion lifting equipment. The safety brake device of the existing rack and pinion lifting equipment is realized by stopping the driving gear from rotating by various methods; but if If there is a problem with the drive 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 reliable safety mechanisms that can deal with problems including drive gear and similar safety issues. moving device

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 lever 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 lever 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). Figure 1-7As shown in paragraphs [0004], [0005], [0006] and [0007], due to the coordination and coordinatio...

Embodiment 2

[0020] Example 2, Figure 8 , Figure 9 It is also a schematic diagram of embodiment 2, which shows a kind of elevator equipped with the horizontal electromagnetic lever 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 lever safety brake device for gear and rack lifting equipment. The horizontal electromagnetic lever safety brake device comprises a bearing component, a track assembly, a movable rack, a movable rack limiting mechanism, a movable rack control mechanism, a control device for the movable rack control mechanism, and a manual unlocking mechanism, wherein after entering a braking state, the top of the movable rack is in direct contact with a main bearing structure of a sedan of the lifting equipment or is in contact with and borne by an intermediate transition bearing component; the movable rack control mechanism controls the movable rack to horizontally move on a track hole or is remained at a braking position meshed with a lifting equipment driving rack or completely separated from the lifting equipment driving rack and has a free position with a clearance section. With the adoption of a lever and an electromagnetic impeller, the deadweight of the device is lightened, and the cost is saved; the beneficial effects of saving an effective space, saving energy and improving the leveling accuracy and safety protection braking quality are achieved.

Description

technical field [0001] The invention relates to the field of safety braking devices for lifting equipment, in particular to a horizontal electromagnetic lever safety braking device for rack and pinion lifting equipment.
