Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical brakes, and in particular relates to a brake device for a discharge trolley. Background Art
[0002] The steelmaking converter unloading trolley is a key equipment for transporting converter alloys. Its function is to unload the alloy from the belt conveyor to any point in the middle of the conveyor, so as to utilize the site to pile up or distribute materials in a larger range. With the acceleration of the steelmaking smelting rhythm, the frequency of use of the unloading trolley is also becoming more and more frequent. The current unloading trolley brake uses a motor to obtain power to open the electromagnetic brake. This method often causes the brake to fail to open due to a broken brake or a broken brake output line, which burns the motor, the contactor, and the thermal relay, causing the trolley to get stuck on the track due to the brake failure. It takes at least 30 minutes for the operator to repair the brake. These 30 minutes will cause the entire furnace to stop, seriously affecting the smelting and steelmaking production.
[0003] In view of this, in order to solve the above technical problems, the utility model proposes a brake device for a discharge trolley which is easy to maintain, has a simple structure and is easy to operate, and can reduce the impact on production progress caused by problems with the brake of the discharge trolley. Summary of the invention

[0005] A brake device for a unloading trolley comprises a mounting plate arranged at the rear side of a rotating wheel of the trolley and connected to a side wall of the trolley, the mounting plate being provided with a through hole for passage of a rotating shaft of the trolley, a first brake arm and a second brake arm being rotatably connected to the lower side of the mounting plate via a first fixed shaft, a Y-shaped pulling arm being rotatably connected to the upper side of the mounting plate via a second fixed shaft, one free end of the Y-shaped pulling arm being rotatably connected to a driving mechanism, and the other two free ends being rotatably connected to the first brake arm and the second brake arm via connecting rods, a telescopic spring being connected between the first brake arm and the second brake arm, the first brake arm and the second brake arm being provided with mounting blocks facing the rotating wheel direction, and both mounting blocks being provided with brake blocks opposite to the rotating wheel.
[0006] Furthermore, the telescopic spring is arranged between the first brake arm and the second brake arm away from the first fixed shaft end.
[0007] Furthermore, cushion blocks extending toward the rotating wheel are provided on the upper and lower sides of the mounting plate, and the first fixed shaft and the second fixed shaft are fixedly arranged on the two cushion blocks respectively.
[0008] Furthermore, the driving mechanism is an electric cylinder, and the electric cylinder is detachably connected to the mounting plate.
[0009] Still further, a fixing sleeve through which the rotating shaft of the trolley can pass is sleeved on the mounting plate.
[0010] The beneficial effects of the present utility model are as follows:
[0011] A brake device for a discharging trolley of the present utility model controls the start of the driving motor through a mounting plate connected to the side wall of the trolley behind the runner, a first brake arm and a brake block thereon, a second brake arm and a brake block thereon, a connecting rod, a Y-shaped pulling arm, a telescopic spring and a driving mechanism. When the output shaft of the driving motor retracts, the two brake blocks will fit with the runner to complete the brake braking. The device has few components, a simple structure, and the components are arranged on the side wall of the trolley and are easy to damage, which can speed up the maintenance progress and further reduce the impact on the production progress due to brake problems.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0018] Refer to Figures 1-4A brake device for a unloading trolley comprises a mounting plate 2 which is arranged at the rear side of a trolley rotating wheel 1 and connected to a side wall of the trolley, the mounting plate 2 being detachably connected to the side surface of the trolley by bolts, a through hole for the trolley rotating shaft to pass through is opened on the mounting plate 2, a first brake arm 3 and a second brake arm 4 are rotatably connected to the lower side of the mounting plate 2 by a first fixed shaft, a Y-shaped pulling arm 5 is rotatably connected to the upper side of the mounting plate 2 by a second fixed shaft, a free end of the Y-shaped pulling arm 5 is rotatably connected to a driving mechanism 6, and the other two free ends are rotatably connected to the first brake arm 3 and the second brake arm 4 by connecting rods 7, a telescopic spring 8 is connected between the first brake arm 3 and the second brake arm 4, a mounting block 9 facing the direction of the rotating wheel 1 is provided on the first brake arm 3 and the second brake arm 4, the mounting block 9 is an L-shaped structure, and a brake block 10 opposite to the rotating wheel 1 is provided on the two mounting blocks 9.
[0019] Preferably, the telescopic spring 8 is arranged between the first brake arm 3 and the second brake arm 4 away from the first fixed shaft end.
[0020] Cushion blocks 11 extending toward the rotating wheel 1 are disposed on the upper and lower sides of the mounting plate 2 , and the first fixed shaft and the second fixed shaft are fixedly disposed on the two cushion blocks 11 , respectively, so as to facilitate the device to have a more stable brake part.
[0021] The preferred driving mechanism 6 is an electric cylinder, which is detachably connected to the mounting plate 2 .
[0022] The mounting plate 2 is provided with a fixing sleeve 12 through which the rotating shaft of the trolley can pass, so that the whole device is more stable when the rotating wheel 1 is tightened or loosened.
[0023] Working principle: when the trolley needs to stop, the output shaft of the start-up driving mechanism 6 is controlled to retract, and the two brake blocks 10 will fit with the rotating wheel 1 to complete the braking.
