It is composed of an electric motor, brake, coupling, reduction box, traction wheel, frame and guide wheel, and an auxiliary handwheel. Its function is to convey and transmit power to make the elevator run. Before tightening the bolts, the joints between the traction machine base and the mounting plane must be checked with a feeler gauge to see if there is any gap. If there is a gap, fill it with a gasket. Any form of gap will affect the operating function of the traction machine or elevator. The detection of the single-group brake components of the traction machine's brake needs to be coordinated with the rotary drive. When using heavy objects for detection, the single-group brake components of the traction machine's brake need to be connected to the output shaft of the rotary drive.

[0012] Compared with the prior art, the present invention provides a single-group brake component detection device for an elevator traction machine brake, which has the following beneficial effects:

[0013] 1. The elevator traction machine brake single-group brake component detection device is designed by placing a counterweight object in the counterweight box, and then fixing the brake device to be detected on the mounting frame, and then fixing the brake device to the rotating column on the left. Then, by moving two square bars to the left, the extrusion rod can be driven to move to the left, so that the four blocks can be squeezed by the round table block, and the rotary drive is started to rotate the round tube slowly. When the block is aligned with four of the extrusion blocks, the user can squeeze the four blocks to move outward from the four slots by moving two square bars. The round tube can drive the rotating tube to rotate through the clamping block, thereby driving the winding roller to rotate and wind up the tension rope to drive the counterweight box to move upward. When the counterweight box is suspended in the air, the square bar can be moved to the right, so that the rebound of the pressure spring a will push the clamping block into the slot through the extrusion block, thereby rotating the tube so that its support can rotate autonomously. In this way, the counterweight box will pull the winding roller to rotate due to gravity, and then start the brake device to test whether the brake device can brake the winding roller. By detecting in this way, there is no need to rotate the output shaft of the rotation drive, so that damage to the rotation drive can be avoided.

[0014] 2. The elevator traction machine brake single-group brake component detection device can move the two lifting frames downward and utilize the inclined surfaces of the two trapezoidal blocks at the top to move the square bar to the right. On the contrary, by moving the two lifting frames upward, the inclined surfaces of the two trapezoidal blocks at the bottom can be used to press the square bar to the left, thereby making it convenient for users to move the two square bars.

[0015] 3. The elevator traction machine brake single-group brake component detection device can keep the lifting frame stable when it moves up and down through the square frame, so that the counterweight box can be kept stable when it moves up and down through four connecting ropes, so as to avoid the single connection point of the tension rope causing the counterweight box to tilt when it moves up and down.

[0016] 4. The elevator traction machine brake single-group brake component detection device places a half frame on two trapezoidal bars and fixes two small columns on a wall or other fixed objects. When the counterweight box moves upward to a suitable position, the two trigger blocks will move upward to drive the left ends of the two trigger bars to tilt, so that the two trigger bars can move downward to pull the two transmission ropes, thereby driving the two trapezoidal bars to move into the two square boxes respectively, so that the half frame will lose support and move downward, so that the two square bars can be driven to move to the right through the two downward-moving lifting frames, so that the rotating tube will lose support and can rotate autonomously, so that the counterweight box will fall, so that the user can start the brake device for testing, so that it can automatically fall when the counterweight box rises to a certain height.

[0017] 5. The elevator traction machine brake single-group brake component detection device can reduce the friction of the trapezoidal bar by rotating the rod, thereby preventing excessive friction from affecting the falling of the half frame. The limit rod can maintain the stability of the extrusion block when it moves, and the two circular plates can limit the position of the tension rope when it is wound.

By putting the counterweight object into the counterweight box 15, and then fixing the brake device to be detected on the mounting frame 1, and then fixing the brake device to the rotating column 10 on the left, the two square bars 20 can be moved to the left, so that the extrusion rod 41 can be driven to move to the left, so that the four blocks 46 can be squeezed by the truncated table block 52, and the rotary drive 2 is started at the same time to make the round tube 34 rotate slowly. When the blocks 46 are aligned with four of the extrusion blocks 47, the user can squeeze the four blocks 46 to move outward from the four slots 5 by moving the two square bars 20, so that the round tube 34 can drive the rotating tube 43 to rotate through the blocks 46, thereby driving the winding roller 9 to rotate.

A lifting frame 3 is provided on each of the two square bars 20, and two trapezoidal blocks 21 are fixedly installed in each of the two lifting frames 3. The two trapezoidal blocks 21 in the lifting frame 3 are respectively arranged at the upper left corner and the lower right corner of the lifting frame 3.Two groups of support plates 4 are arranged on the mounting frame 1, and half frames 24 are fixedly installed on the lower sides of the two lifting frames 3, and each support plate 4 is respectively fitted with the left and right sides of the two lifting frames 3, and each support plate 4 is respectively fitted with the left and right sides of the half frames 24. By moving the two lifting frames 3 downward, the inclined surfaces of the two trapezoidal blocks 21 at the top can be used to squeeze the square bar 20 to the right. On the contrary, by moving the two lifting frames 3 upward, the inclined surfaces of the two trapezoidal blocks 21 at the bottom can be used to squeeze the square bar 20 to the left, so that the user can move the two square bars 20 conveniently. A square frame 12 is fixedly installed on the lower side of the mounting frame 1, and a lifting block 13 is movably connected in the square frame 12. The lifting block 13 is fixedly connected to the tension rope 7, and four connecting ropes 14 are fixedly installed on the lower side of the lifting block 13. The lower ends of the four connecting ropes 14 are fixedly connected to the counterweight box 15, and trigger blocks 16 are fixedly installed on the front and rear sides of the counterweight box 15. The square frame 12 can keep the lifting frame 13 stable when it moves up and down, so that the four connecting ropes 14 can keep the counterweight box 15 stable when it moves up and down, so that the single connection point of the tension rope 7 can be avoided to cause the counterweight box 15 to tilt when it moves up and down. Two square boxes 23 are fixedly installed on the mounting frame 1, and trapezoidal bars 25 are movably connected in the two square boxes 23. Two pressure springs b30 are fixedly installed on the side away from each other of the two trapezoidal bars 25. Fixed plates 31 are fixedly installed on the four pressure springs b30. The four fixed plates 31 are respectively fixedly installed in the two square boxes 23. The two trapezoidal bars 25 are connected to each other. A transmission rope 19 is fixedly installed on the side away from each other, a small rod 33 is fixedly installed in the two square boxes 23, and a circular groove 32 is opened on the lower wall of the two square boxes 23. The two transmission ropes 19 pass through the two circular grooves 32 after passing through the two small rods 33 respectively. The lower ends of the two transmission ropes 19 are fixedly installed with a trigger bar 18, and the two trigger bars 18 are movably penetrated with a small column 17. By placing the half frame 24 on the two trapezoidal bars 25, the two small columns are fixed on a wall or other fixed object. When the counterweight box 15 moves upward to a suitable position, the two trigger blocks 16 will move upward to drive the left ends of the two trigger bars 18 to tilt up, so that the two trigger bars 18 can move downward to pull the two transmission ropes 19, so that the two trapezoidal bars 25 can be driven to move to the two sides. The square box 23 moves, so that the half frame 24 will lose support and move downward, so that the two square bars 20 can be driven to move to the right through the two downwardly moving lifting frames 3, so that the rotating tube 43 will lose support and can rotate autonomously, so that the counterweight box 15 will fall, so that the user can start the brake device for testing, so that the counterweight box 15 can automatically fall when it rises to a certain height. A groove 28 is provided on the side where the two trapezoidal bars 25 are close to each other, and a cross bar 27 is fixedly installed in the two grooves 28. A rotating rod 26 is movably sleeved on the two cross bars 27. A limit rod 50 is arranged in each pressure spring a49, and each limit rod 50 is fixedly connected to each square block 48 respectively, and each limit rod 50 movably passes through each extrusion block 47.Two circular plates 8 are fixedly sleeved on the winding roller 9. The friction of the trapezoidal bar 25 can be reduced by rotating the rod 26, so as to prevent the half frame 24 from falling due to excessive friction. The stability of the extrusion block 47 during movement can be maintained by the limit rod 50. The position of the tension rope during winding can be limited by the two circular plates 8.

[0034] When in use, the first step is: put the counterweight object into the counterweight box 15, then fix the brake device to be tested on the mounting frame 1, and then fix the brake device to the rotating column 10 on the left, and then move the two square bars 20 to the left, so that the extrusion rod 41 can be driven to move to the left, so that the four blocks 46 can be squeezed by the truncated table block 52, and the rotation drive 2 is started to rotate the round tube 34 slowly. When the block 46 is aligned with four of the extrusion blocks 47, the user can squeeze the four blocks 46 to move outward from the four slots 5 by moving the two square bars 20, so that the round tube 34 can pass. The rotating tube 43 is driven to rotate through the clamping block 46, thereby driving the winding roller 9 to rotate and wind up the tension rope 7 to drive the counterweight box 15 to move upward. When the counterweight box 15 is suspended in the air, the square bar 20 can be moved to the right, so that the rebound of the pressure spring a49 will push the clamping block 46 into the slot 5 through the extrusion block 47, so that the rotating tube 43 allows its support to rotate autonomously. In this way, due to gravity, the counterweight box 15 will pull the winding roller 9 to rotate, and then start the brake device to test whether the brake device can brake the winding roller 9. Through such detection, there is no need to rotate the output shaft of the rotary drive 2, so that damage to the rotary drive 2 can be avoided.

[0035] Step 2: By moving the two lifting frames 3 downward, the oblique surfaces of the two trapezoidal blocks 21 at the top can be used to squeeze the square bar 20 to the right. Conversely, by moving the two lifting frames 3 upward, the oblique surfaces of the two trapezoidal blocks 21 at the bottom can be used to squeeze the square bar 20 to the left, thereby making it convenient for users to move the two square bars 20.

[0036] Step 3: The lifting frame 13 can be kept stable when moving up and down through the square frame 12, so that the counterweight box 15 can be kept stable when moving up and down through the four connecting ropes 14, so that the single connection point of the tension rope 7 can be prevented from causing the counterweight box 15 to tilt when moving up and down.

[0037] Step 4: By placing the half frame 24 on the two trapezoidal bars 25 and fixing the two small columns on a wall or other fixed object, when the counterweight box 15 moves upward to a suitable position, the two trigger blocks 16 will move upward to drive the left ends of the two trigger bars 18 to tilt up, so that the two trigger bars 18 can move downward to pull the two transmission ropes 19, thereby driving the two trapezoidal bars 25 to move into the two square boxes 23 respectively, so that the half frame 24 will lose support and move downward, so that the two square bars 20 can be driven to move to the right through the two downward moving lifting frames 3, so that the rotating tube 43 will lose support and can rotate autonomously, so that the counterweight box 15 will fall, so that the user can start the brake device for testing, so that the counterweight box 15 can automatically fall when it rises to a certain height.

[0038] Step 5: The friction of the trapezoidal bar 25 can be reduced by rotating the rod 26, thereby preventing excessive friction from affecting the falling of the half frame 24. The stability of the extrusion block 47 during movement can be maintained by the limit rod 50, and the position of the tension rope during winding can be limited by the two circular plates 8.
