Description

Technical Field

[0001] The utility model relates to the field of electromagnetic brake equipment, in particular to a waterproof electromagnetic brake. Background Art

[0002] Electromagnetic brake is a brake that uses electromagnetic effect to achieve braking. Electromagnetic brake is an ideal automatic actuator in modern industry. It mainly plays the role of transmitting power and controlling movement in mechanical transmission system. It has the advantages of compact structure, simple operation, sensitive response, long life, reliable use and easy remote control.

[0003] When the electromagnetic brake is powered on, a large amount of heat will be generated inside the shell. If the heat generated inside the shell is not dissipated in time, the electronic components of the electromagnetic brake will be in a high-temperature working environment for a long time, which will shorten the service life of the electronic components. If the electromagnetic brake is to be cooled, it is generally done through a heat pipe.

[0004] The current heat dissipation pipe is generally composed of a pipe combined with a filter installed at the outlet of the pipe; when the electromagnetic brake is running, the heat generated is discharged through the pipe connected to the shell to achieve the heat dissipation effect; however, this heat dissipation method also has some defects. For example, when the electromagnetic brake is not working, since the pressure inside the shell is consistent with that of the outside air, it is easy for dust and water vapor in the outside air to enter the shell, causing oxidation corrosion to the electronic components inside the shell, shortening the service life of the entire waterproof electromagnetic brake;

[0005] In view of the problems in the above background technology, the utility model aims to provide a waterproof electromagnetic brake. Utility Model Content

[0006] The purpose of the utility model is to provide a waterproof electromagnetic brake to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A waterproof electromagnetic brake, comprising:

[0009] A brake body, wherein a driving wheel is movably mounted on one side of the brake body, a driving shaft is arranged at the axis of the driving wheel, and one end of the driving shaft extends into the interior of the brake body;

[0010] A gear sleeve is movably mounted at the axis center of the brake body, and the axis center of the gear sleeve movably mounted at the axis center of the brake body is connected to the outer side of the drive shaft through a key;

[0011] In addition, the brake body is also connected to a heat dissipation pipe which is used to brake the rotating drive wheel when the brake body is started, and can also ensure that when the brake body stops working, it is not easy for external dust and water droplets to enter the inside of the brake body, thereby achieving moisture-proof and dust-proof performance.

[0012] As a further solution of the utility model: a threaded groove is provided on the outer surface of the heat dissipation tube, a filter hole is provided on the upper surface of the heat dissipation tube, a filter frame is installed inside the filter hole, and a filter screen is placed inside the filter frame; an air inlet is provided at the lower end of the heat dissipation tube.

[0013] As a further solution of the utility model: the interior of the heat dissipation pipe is divided into an upper air cavity and a lower air cavity, and the upper air cavity and the lower air cavity are connected by a guide pipe; a positioning frame is installed inside the upper air cavity, the positioning frame is connected to the upper exhaust pipe, and the top of the upper exhaust pipe is connected to the filter hole position; the interior of the lower air cavity is divided into an inner air cavity and an outer air cavity, and the bottom end of the inner air cavity is connected to the outer air cavity by an air guide pipe; a floating ball is placed inside the inner air cavity, and air distribution pipes are installed on both sides of the inner wall of the upper end of the inner air cavity, and an air distribution port is opened at the lower end of the air distribution pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] Compared with the current electromagnetic brake, the waterproof electromagnetic brake has the following advantages:

[0016] The heat dissipation pipe is installed on the brake body, and the inside of the heat dissipation pipe is divided into an upper air cavity and a lower air cavity;

[0017] When the brake is powered on and in operation, a large amount of heat is generated inside the brake body, which increases the air pressure inside the brake body and generates expansion pressure, so that hot air enters and is discharged through the lower air cavity and the upper air cavity in turn, thus achieving heat dissipation for the running brake;

[0018] When the brake stops working, the hot air inside the brake body is discharged to a small space volume, which is not enough to generate sufficient buoyancy for the float ball inside the lower air cavity. The float ball will block the air guide pipe under its own gravity, thereby preventing dust and water droplets from the outside from passing through the inner air cavity into the outer air cavity. At the same time, since the air guide pipe and the air guide pipe are both in a protruding state, it is not easy for dust or water droplets that enter the heat dissipation pipe to pass through the heat dissipation pipe into the brake body.

[0019] The heat dissipation pipe is provided so that the entire waterproof electromagnetic brake has a heat dissipation function and can also achieve waterproof and dustproof performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A brake body 3, wherein a driving wheel 2 is movably mounted on one side of the brake body 3, a driving shaft 1 is arranged at the axial center of the driving wheel 2, and one end of the driving shaft 1 extends into the interior of the brake body 3;

[0029] A gear sleeve 5 is movably mounted at the axis center of the brake body 3, and the gear sleeve 5 movably mounted at the axis center of the brake body 3 is connected to the outer side of the drive shaft 1 at the axis center through a key;

[0030] In addition, the brake body 3 is also connected to a heat dissipation pipe 4, which is used to brake the rotating driving wheel 2 when the brake body 3 is started, and can also ensure that when the brake body 3 stops working, it is not easy for external dust and water droplets to enter the brake body 3, thereby achieving moisture-proof and dust-proof performance;

[0031] In the embodiment of the utility model, when the waterproof electromagnetic brake is used, for example, when the brake body 3 is not powered on, the driving wheel 2 installed on one side of the brake body 3 rotates simultaneously with the rotation of the driving shaft 1, and when the driving shaft 1 rotates, the gear sleeve 5 located on the outer side of the driving shaft 1 also rotates simultaneously;

[0032] When the brake body 3 is powered on and brakes the rotating driving wheel 2, after the brake body 3 brakes the rotating gear sleeve 5, the driving shaft 1 arranged at the axial position of the gear sleeve 5 will also stop rotating, thereby stopping the driving wheel 2 from rotating, thereby achieving braking operation; and when the brake body 3 brakes the driving wheel 2, a large amount of heat generated inside the brake body 3 can be discharged through the connected heat dissipation pipe 4 to achieve ventilation and heat dissipation; and when the brake body 3 stops working normally, the heat dissipation pipe 4 will provide moisture-proof and waterproof performance for the brake body 3;

[0033] See also Figure 2 In one embodiment of the utility model, a thread groove 9 is provided on the outer surface of the heat dissipation pipe 4, and the thread groove 9 provided on the outer surface of the heat dissipation pipe 4 facilitates the rapid and movable installation between the entire heat dissipation pipe 4 and the brake body 3; a filter hole 6 is provided on the upper end surface of the heat dissipation pipe 4, a filter frame 8 is installed inside the filter hole 6, and a filter screen 7 is placed inside the filter frame 8; an air inlet 10 is provided at the lower end of the heat dissipation pipe 4, and the air inlet 10 is used to guide the hot air into the heat dissipation pipe 4;

[0034] The filter hole 6 is used to guide and discharge the heat generated by the brake body 3 during braking, and the filter screen 7 is used to filter and intercept the air entering the heat dissipation pipe 4 from the outside. The filter frame 8 is convenient for the filter screen 7 and the filter hole 6 to be quickly installed and disassembled.

[0035] See also Figure 3 In the embodiment of the utility model, the interior of the heat dissipation tube 4 is divided into an upper air cavity and a lower air cavity, and the upper air cavity and the lower air cavity are connected through a guide tube 13; a positioning frame 12 is installed inside the upper air cavity, and the positioning frame 12 is connected to the upper exhaust pipe 11, and the top of the upper exhaust pipe 11 is connected to the position of the filter hole 6; the interior of the lower air cavity is divided into an inner air cavity 17 and an outer air cavity 19, and the bottom end of the inner air cavity 17 is connected to the outer air cavity 19 through an air guide tube 18; a floating ball 16 is placed inside the inner air cavity 17, and air distribution pipes 14 are respectively installed on both sides of the inner wall of the upper end of the inner air cavity 17, and an air distribution port 15 is opened at the lower end of the air distribution pipe 14;

[0036] In the embodiment of the utility model, for example, when the brake body 3 is used to brake the rotating driving wheel 2 and a large amount of heat is generated inside the brake body 3, the air pressure inside the brake body 3 increases, generating a diffusion pressure, and then the hot air enters the outer air cavity 19;

[0037] When the hot air enters the outer air cavity 19, since there is no other opening in the outer air cavity 19, the hot air can only pass through the air guide pipe 18 to enter the inner air cavity 17; and when the hot air enters the inner air cavity 17, it generates buoyancy on the float 16, so that the float 16 is lifted inside the inner air cavity 17; until the float 16 finally moves to the top position inside the inner air cavity 17, so that the hot air enters from the air distribution port 15 along the two ends of the inner air cavity 17, and finally is discharged from the air distribution pipe 14, and then passes through the connected guide pipe 13 to enter the upper air cavity, and finally is discharged from the upper exhaust pipe 11;

[0038] When the hot air inside the brake body 3 is discharged to a small space volume, which is not enough to generate sufficient buoyancy for the float 16, the float 16 will block the air guide pipe 18 under its own gravity, thereby preventing dust and water droplets from the outside from passing through the inner air cavity 17 into the outer air cavity 19; at the same time, since the air guide pipe 13 and the air guide pipe 18 are both in a protruding state, it is not easy for dust or water droplets that enter the heat dissipation pipe 4 to pass through the heat dissipation pipe 4 into the brake body 3;
