Abstract
Description
Technical Field
[0001] This utility model relates to the field of mine hoist technology, and in particular to a mine hoist brake shoe gap protection and detection device. Background Technology
[0002] A mine hoist is a large-scale hoisting machine that uses an electric motor to drive a steel wire rope, which in turn moves a container up and down within the mine shaft to complete the transportation task. Mine hoists evolved from primitive water-lifting tools. Modern mine hoists offer large lifting capacities, high speeds, and high safety, and have developed into fully automated heavy-duty mining machinery controlled by electronic computers.
[0003] To this end, patent CN220564071U discloses a brake shoe gap protection and detection device for a mine hoist, comprising: a mounting base on a brake disc, an annular fixing seat welded to the top of the mounting base, and a hydraulic cylinder installed inside the annular fixing seat, with a brake shoe mounting seat fixedly installed at the movable end of the annular fixing seat. This mine hoist brake shoe gap protection and detection device uses the extension of the hydraulic cylinder to make the brake shoe plate contact the brake disc, achieving a braking effect. If the brake shoe plate wears more than 1 mm, the distance α between the brake shoe plate and the brake disc increases. When braking, the stroke distance of the hydraulic cylinder increases, thus increasing the distance by which the transverse movable plate moves towards the brake disc. At this time, the protrusion will directly touch the touch switch and activate the alarm light for warning. In this case, an alarm can be triggered as long as the brake shoe plate wears more than 1 mm, without requiring the brake shoe to be completely worn as in traditional methods. Furthermore, the wear alarm value can be set according to the situation.
[0004] The existing technical solutions described above have the following drawbacks: Although the installation of the heat dissipation mechanism connects air vent one and air vent two, with air vent one being larger than air vent two, allowing air to enter from the larger vent and exit from the smaller vent, the air at the outlet is compressed, increasing the flow rate and carrying away more heat in a short time, thereby cooling the interior of the main structure and protecting internal components from damage due to high temperatures, effectively improving the practicality of the mine and the brake shoe gap protection detection device, although multiple sets of air vents are used to cool the interior of the main structure, in actual use, because the multiple sets of air vents are interconnected with the main structure, during daily storage, external dust and foreign objects are easily attracted to the air vents by static electricity, eventually causing blockages and affecting the heat dissipation effect of the main structure.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 2-5This utility model provides a mine hoist brake shoe gap protection and detection device, comprising:
[0036] Main components: The main components include housing 11, mounting bracket 12, brake cylinder 13, brake shoe block 14 and piston rod 16;
[0037] Mounting bracket 12 is slidably connected to the inside of housing 11, brake cylinder 13 is mounted on the top of mounting bracket 12, piston rod 16 is mounted on the connecting end of brake cylinder 13, and brake shoe block 14 is mounted on the connecting end of piston rod 16.
[0038] The main components also include a phase-type laser rangefinder 15, a buzzer 17, and a signal processor 18;
[0039] A phase-type laser rangefinder 15 is installed on the inner wall of the housing 11, a signal processor 18 is installed on the lower part of the phase-type laser rangefinder 15, and a buzzer 17 is installed on the top of the housing 11.
[0040] The brake cylinder 13 drives the piston rod 16 to work, and the piston rod 16 drives the brake shoe 14 to work. The brake shoe 14 stops the wheel from rotating through friction. When the brake shoe 14 has no wear or very little wear, the phase delay of the laser round trip calculated by the brake shoe 14 exceeds the value set in the signal processor 18. At this time, the signal processor 18 will send a signal to make the buzzer 17 alarm. The staff can notice the wear of the brake shoe 14 at the first time, so that the mine hoist can be stopped in time to replace the brake shoe 14.
[0041] All of the above parts are existing publicly available technologies;
[0042] Heat dissipation assembly: The heat dissipation assembly includes ventilation slots 21, knobs 22, and threaded rods 23;
[0043] Ventilation slots 21 are formed on both sides of the outer wall of housing 11, knobs 22 are rotatably connected to the top two ends of housing 11, and threaded rods 23 are fixedly connected to the bottom end of knobs 22;
[0044] The heat dissipation assembly also includes a screw plate 24 and a mounting slot 25;
[0045] The screw plate 24 is threaded to one end of the threaded rod 23, and the mounting groove 25 is opened at both ends of the housing 11;
[0046] The mounting groove 25 is used to provide sliding space for the screw plate 24. The threaded rod 23 is threadedly connected to the inside of the screw plate 24. There are multiple sets of ventilation grooves 21, which are equally spaced on both sides of the outer wall of the housing 11.
[0047] With the auxiliary cooperation between the ventilation slot 21 and the knob 22, the knob 22 can be rotated while the screw plate 24 is driven to slide vertically down inside the mounting slot 25.
[0048] Working principle: When the staff dissipates heat from the device;
[0049] First, by rotating the knobs 22 at both ends of the top of the housing 11 clockwise, the knobs 22 can rotate, thereby driving the threaded rod 23 to rotate.
[0050] Next, the screw plate 24 can slide vertically upward along the threaded track outside the threaded rod 23 inside the mounting groove 25, which can release the obstruction formed by the screw plate 24 on the ventilation groove 21, so that ventilation can be formed between the housing 11 and the ventilation groove 21, thereby allowing the heat inside the housing 11 to be discharged through the ventilation groove 21.
[0051] This step helps staff remove heat from inside the housing 11 and prevents dust from entering the ventilation slot 21 when the housing 11 is handled and stored.
[0052] Please see Figure 3-4 As shown, this embodiment, based on the above embodiment, also includes auxiliary components;
[0053] The auxiliary components include a connecting groove 31, a pull plate 32, a rotating gear 33, and a toothed plate 34;
[0054] A connecting groove 31 is formed at the top rear end of the housing 11, a pull plate 32 is slidably connected to the inside of the connecting groove 31, a rotating gear 33 is rotatably connected to both sides of the inner wall of the housing 11, and a toothed plate 34 is fixedly connected to both ends of the mounting bracket 12.
[0055] The auxiliary components also include toothed blocks 35;
[0056] The toothed block 35 is fixedly connected to the inner side wall of the pull plate 32, and the rotating gear 33 and the toothed block 35 are meshed together.
[0057] The connecting groove 31 provides space for the pull plate 32 to be pulled out, and the toothed plate 34 is located below the rotating gear 33;
[0058] With the auxiliary cooperation between the connecting groove 31 and the pull plate 32, the pull plate 32 can be pulled upward while the mounting bracket 12 slides outward from the inside of the housing 11.
[0059] Working principle: When the staff is inspecting brake cylinder 13;
[0060] First, by pulling the pull plate 32 inside the connecting groove 31 upward, the pull plate 32 can slide upward, causing the two sets of tooth blocks 35 to slide, so that the two sets of tooth blocks 35 and the rotating gear 33 can mesh and connect.
[0061] Next, the rotating gear 33 can be rotated and meshed with the toothed plate 34, so that the mounting bracket 12 with the toothed plates 34 at both ends can slide out from the inside of the housing 11.
[0062] This step provides staff with ample space for maintenance.
