Embodiment 1
[0036] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the cordless hoist with a booster mechanism brake of the present invention mainly includes a supporting steel beam assembly, a car, a linear motor drive device, a positioning guide device, a braking device, a safety gear protection device, and a buffer device.
[0037] The supporting steel beam assembly 1 is in the shape of a strip, and is installed vertically on the mounting support 2 on the inner wall of the wellbore. A concave bar-shaped groove 1a with an opening facing outward is respectively arranged in the vertical direction as a guide track and a brake track;
[0038] Both sides of the concave strip groove 1a are convex strips I 1b and convex strips II 1c, and the convex strips I 1b or convex strips II 1c are used as brake rails for the safety gear protection device;
[0039] The brake block 103 of the booster caliper brake 10 is held in the concave strip groove 1a. When braking, the b...
Embodiment 2
[0063] The above-mentioned positioning and guiding device of the linear motor mover 6 can also be realized by a linear guide rail and a slider. The linear guide rail is installed on the two sides of the supporting steel beam assembly 1, and the slider is installed on the back iron 6b of the linear motor mover corresponding to side, and aligned with the linear guide rail, the slider can slide freely on the linear guide rail, thereby ensuring that the linear motor mover 6 moves up and down in the vertical direction on the supporting steel beam assembly 1 .
Embodiment 3
[0065] Such as Figure 9 , taking two rows of linear motor stators installed in parallel as an example, but not limited to two rows of linear motor stators. Two rows of linear motor stators 4 are installed in parallel in the vertical direction on the front of the supporting steel beam assembly 1, and each row of linear motor stators 4 is correspondingly arranged with a row of linear motor movers 6, and each row of linear motor stators 4 is a flat and slender structure. Support rails 155 are arranged between the linear motor stators 4 in each row, and support rollers 153 are installed on the linear motor movers 6, corresponding to the support rails 155. The support rollers 153 support the linear motor movers 6 to slide on the support rails 155, which can disperse the linear motor. The normal force of the motor reduces the requirements for the supporting rollers; the side edges of the two rows of linear motor mover back irons 6b are respectively equipped with multiple groups of ...
