Problems solved by technology

[0002] The existing leveling control device of rack and pinion lifting equipment still uses the way of traction lifting equipment, but the rack and pinion lifting equipment has its own characteristics different from traction lifting equipment. According to its characteristics, the existing leveling control It is necessary to improve the device; the existing safety braking device of the rack and pinion lifting equipment is realized by making the drive gear stop rotating through various methods; Gear brakes cannot guarantee reliable braking of lifting equipment. To ensure safety, rack and pinion lifting equipment must be equipped with reliable safety braking devices that can deal with problems including driving gears and similar safety problems.

Embodiment 1

[0022] Example 1, Figure 10 It is a schematic diagram of embodiment 1, and the drawing shows the appearance of the side of the lifting equipment. The horizontal leveling control and safety brake device is installed on the rack and pinion lifting equipment and is temporarily in a free position, and the lifting equipment is ready to run or is running In the situation, Figure 11 It is a schematic diagram of the situation that the horizontal leveling control and safety braking device of embodiment 1 brakes the lifting equipment, (the previous figure 1 , figure 2 , image 3 , Figure 4 , Figure 8 , Figure 9 The left and right mentioned are viewed from the inside of the lifting device to the side of the lifting device. Figure 10 , Figure 11 It is viewed from the outside to the side of the lifting equipment, so the left and right directions are just opposite). Figure 1-9As shown, and [0004] paragraph, [0005] paragraph, [0006] paragraph, [0007] paragraph, [0008] paragr...

Embodiment 2

[0023] Example 2, Figure 10 , Figure 11 It is also a schematic diagram of embodiment 2, which shows an elevator equipped with a horizontal leveling control and safety braking device according to the present invention, and its appearance is the same as Figure 10 , Figure 11 , the internal structure of the horizontal leveling control and safety brake device and its functions are described in Figure 1-9 As shown, and described in [0004], [0005], [0006], [0007], [0008], and [0009], the working principle is the same as that described in [0022].

Abstract

The invention provides a horizontal flat layer control and safety brake device of pinion-and-rack lifting equipment. The horizontal flat layer control and safety brake device is horizontally arranged, and comprises a bearing part, a rail assembly, a movable rack, a movable rack limiting mechanism, a movable rack operating mechanism, a movable rack operating mechanism control device and a manual unlocking mechanism, wherein the movable rack is operated by the horizontally-arranged movable rack operating mechanism to horizontally move on a rail hole or to stay at several certain positions, including a brake position meshed with a lifting equipment drive rack or a free position which is completely divorced from the lifting equipment drive rack by a gap. The flat layer control is performed in a rack-meshed manner, and the horizontal flat layer control and safety brake device is horizontally arranged at a top or bottom position, thereby achieving the beneficial effects of saving the effective space, remarkably improving the flat layer precision, and safely protecting the brake quality.

Description

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