It is characterized in that there is also an automatic travel device installed in the middle of the belt frame; the automatic travel device includes a fixed frame, an automatic travel wheel, a wheel support frame, a motor and a reducer; the automatic travel wheel is installed at the lower part of the wheel support frame through an axis, and the motor and the reducer are installed at the upper part of the support frame; a small sprocket is installed on the output shaft of the reducer, and a large sprocket is installed on the shaft of the travel wheel, and the large sprocket and the small sprocket are connected by a chain; a steering shaft is provided on the wheel support frame, and a steering rod for manual operation is also provided on the upper part of the steering shaft, and the steering shaft is installed in a steering sleeve on the fixed frame.

[0003] The above-mentioned travel wheel has the reducer installed on the external frame of the travel wheel. The motor power is relatively large, the reducer box is large, and it occupies a large space. In addition, it requires additional mounting brackets and protective covers, which makes installation difficult. The bare motor reducer brings certain safety hazards. Summary of the invention

[0004] The utility model aims to solve the deficiencies in the prior art and provide a roller type traveling wheel for a belt conveyor.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented according to the following technical scheme:

[0006] A roller type walking wheel of a belt conveyor is installed on the frame of the belt conveyor, comprising a cylindrical hub, a roller installed outside the cylindrical hub, a tire installed outside the roller, fixed transmission shafts are respectively fixed to the centers of both ends of the cylindrical hub, the ends of the fixed transmission shaft are rotatably installed in bearing seats fixed to the frame of the belt conveyor, and the inner walls of both ends of the roller are rotatably connected to the bearing seats; a planetary reduction motor is axially fixed in the cylindrical hub, a transmission gear is axially fixed to the end of the output shaft of the planetary reduction motor, an inner gear ring is provided on the inner ring of the roller corresponding to the outer periphery of the transmission gear, and the inner gear ring is meshed with the transmission gear.

[0007] Furthermore, the planetary reduction motor adopts an AC servo control system to control the forward and reverse rotation of the planetary reduction motor.

[0008] Furthermore, the rollers at both ends of the tire are sleeved with elastic retaining rings, and the elastic retaining rings fix the tire on the rollers.

[0009] Furthermore, one or more tires are installed outside the drum.

[0010] Compared with the prior art, the utility model installs the planetary reduction motor inside the wheel hub, which saves external space, avoids the planetary reduction motor from being hit by external forces, and is safer and more reliable; all manufacturing is completed in the factory, and actual use only requires the roller tire moving device to be installed on the equipment, reducing the difficulty of on-site installation.

[0011] Adopt AC servo control system, high-precision repeated positioning, unmanned operation and remote control; control the motor to rotate in the opposite direction to achieve braking, eliminating the need for brakes and simplifying the equipment structure; wide speed adjustment range, motor overload 300%, suitable for a variety of working conditions.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] like Figure 1 , Figure 2 As shown, this embodiment exemplarily shows a roller type running wheel of a belt conveyor, which is installed on a frame 10 of the belt conveyor, and includes a cylindrical hub 1, a roller 7 installed outside the cylindrical hub 1, and a tire 8 installed outside the roller 7, as shown in FIG. Figure 1As shown, two tires 8 are installed on the drum 7 of this embodiment, and elastic retaining rings 9 are sleeved on the drum 7 at both ends of the tires 8, and the elastic retaining rings 9 fix the tires 8 on the drum 7; fixed transmission shafts 2 are fixed to the centers of both ends of the cylindrical hub 1, and the ends of the fixed transmission shaft 2 are rotatably mounted in the bearing seat 3 fixed on the frame 10 of the belt conveyor, and the inner walls of the two ends of the drum 7 are rotatably connected to the bearing seat 3, and the bearing seat 3 is mainly used to support and position the drum 7; a planetary reduction motor 4 is axially fixed in the cylindrical hub 1, and the planetary reduction motor 4 adopts an AC servo control system (which can be directly purchased on the market) to control the forward and reverse rotation of the planetary reduction motor to achieve braking; a transmission gear 5 is axially fixed to the output shaft end of the planetary reduction motor 4, and an inner gear ring 6 is provided on the inner ring of the drum 7 corresponding to the outer circumference of the transmission gear 5, and the inner gear ring 6 is meshed with the transmission gear 5; for example, when the planetary reduction motor 4 rotates clockwise (forward), it will drive the transmission gear 5 to rotate clockwise, and the transmission gear 5 will drive the drum 7 to reverse, that is, the travel wheel retreats; on the contrary, the travel wheel moves forward.

[0017] like Figure 2 , Figure 3 As shown, when in use, the bearing seat 3 is installed at the place where the travel wheel needs to be installed at the bottom of the frame 10 of the belt conveyor, and then the tire 8 is installed on the roller 7 and fixed at both ends with elastic retaining rings 9, and then the fixed transmission shaft 2 is installed in the bearing seat 3, that is, the installation of the travel wheel is completed, and the planetary reduction motor 4 is controlled by the AC servo control system to rotate forward to make the travel wheel move backward or reverse to make the travel wheel move forward. Of course, during the process of the travel wheel moving forward, the planetary reduction motor 4 can also be controlled by the AC servo control system to reverse to achieve the purpose of braking.
