Description

Technical Field

[0001] This utility model relates to the field of wheeled excavator technology, specifically to an integrated wheeled excavator braking and steering device. Background Technology

[0002] Wheeled trenchers are earthmoving machines that use tires as their walking components and employ hydraulic digging principles. They are mainly used for small to medium-sized construction projects such as municipal maintenance and highway construction. Their walking speed reaches 20-35 km / h, or 25-40 km / h, and they are characterized by self-transfer and quick changing of operating devices.

[0003] However, existing integrated wheel-type excavator braking and steering devices have the following drawbacks:

[0004] (1) Existing integrated wheel excavators generally require long-term operation. However, since there is no heat dissipation structure inside the wheel excavator, the internal components may overheat after long-term use, causing the steering mechanism to stop.

[0005] (2) When existing wheeled excavators are used, they are generally used in outdoor working environments. Outdoor environments have a lot of soil, stones and mud that may enter the connection between the chassis and the cab. If they fall into the steering mechanism, they may cause damage to the main gear. Utility Model Content

[0006] The purpose of this invention is to provide an integrated wheel-digger braking and steering device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated wheel excavator braking and steering device, including a heat dissipation assembly and a protective assembly. The heat dissipation assembly consists of a base, a main gear, a bearing, a hydraulic drive motor, a conveying pipe, a first air duct, a second air duct, a first fan, a second fan, a connecting rod, a first gear, and a second gear. The inner wall of the base is provided with a bearing, and the surface of the bearing is equipped with a hydraulic drive motor on one side of the main gear. The inner bottom wall of the base is equipped with a conveying pipe located below the bearing. The top end of the conveying pipe has a first air duct, and the side of the first air duct has a second air duct. The inner wall of the first air duct is provided with a first fan, and the inner wall of the second air duct is provided with a second fan. The bottom end of the main gear is located between the first fan and the second fan, and a connecting rod is provided between the main gear and the first fan. The surface of the connecting rod is equipped with a first gear, and the surfaces of the first fan and the second fan are equipped with a second gear.

[0008] The protective component consists of a protective cover and a brush. The protective cover is provided at the top of the base, and the brush is provided on the surface of the protective cover.

[0009] Optionally, an oil tank is provided on the inner wall of the base on one side of the hydraulic drive motor. A transmission pipe is installed on one side of the oil tank. The oil tank is connected to the hydraulic drive motor through the transmission pipe. The oil tank is used to add hydraulic oil. The hydraulic oil can be transported to the hydraulic drive motor through the transmission pipe to drive the main gear to rotate.

[0010] Optionally, the second gear has the same size as the first gear, and the second gear meshes with the first gear. The rotation of the first gear can drive the second gear to rotate clockwise and counterclockwise, thereby driving the first and second fans to rotate and dissipate heat. This eliminates the need to use the power supply of the wheel excavator, reducing energy consumption.

[0011] Optionally, the output end of the hydraulic drive motor is meshed with the main gear, and a drive rod is installed on the inner bottom wall of the main gear. The drive rod is installed to connect with the cab and can drive the drive rod to rotate and steer the cab when the main gear rotates.

[0012] Optionally, the base has air inlet slots on its side, which are arranged at equal intervals. The air inlet slots can work with the heat dissipation components to dissipate heat from the interior, forming a convection channel and accelerating the flow of air.

[0013] Optionally, the top of the base has a circular groove on the inner wall of the protective cover, and the circular groove is located on the surface of the drive rod. The circular groove is used to limit the movement of the drive rod.

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

[0015] 1. This integrated wheel-driven excavator braking and steering device, through the setting of a heat dissipation component, allows the hydraulic drive motor, powered by an external power source, to rotate its output end during use. The output end meshes with the main gear, driving the main gear to rotate. The rotation of the main gear drives the connecting rod to rotate, which in turn drives the first gear to rotate. The first gear meshes with the second gear fixed to the first and second fans. When the main gear rotates clockwise or counterclockwise, the first gear drives the second gear to rotate, which in turn drives the first and second fans to perform exhaust and intake operations through the first and second air slots opened in the conveying pipe. The first and second fans can switch between intake and exhaust according to the rotation of the main gear, achieving the effect of dissipating internal heat and delivering external air for heat dissipation, thereby extending the service life of the device and reducing mechanical failures.

[0016] 2. This integrated wheel-type excavator braking and steering device, through the setting of protective components, features a conical protective cover with a sloping surface. When stones pass through the brush and come into contact with the protective cover, they can slide off the surface of the protective cover and not enter the base. The brush acts as the first layer of barrier, blocking most of the mud. During cleaning, a water gun is used to clean the mud on the brush surface and the stones on the protective cover surface, thereby protecting the main gear. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4As shown, the technical solution provided by this utility model is an integrated wheel excavator braking and steering device, including a heat dissipation component 1 and a protective component 2. The heat dissipation component 1 consists of a base 101, a main gear 102, a bearing 103, a hydraulic drive motor 104, a conveying pipe 105, a first air duct 106, a second air duct 107, a first fan 108, a second fan 109, a connecting rod 1010, a first gear 1011, and a second gear 1012. The inner wall of the base 101 is provided with a bearing 103, and the surface of the bearing 103 is mounted on one side of the main gear 102. A hydraulic drive motor 104 is provided. A conveying pipe 105 is installed on the inner bottom wall of the base 101 below the bearing 103. A first air duct 106 is opened at the top of the conveying pipe 105, and a second air duct 107 is opened on one side of the first air duct 106. A first fan 108 is installed on the inner wall of the first air duct 106, and a second fan 109 is installed on the inner wall of the second air duct 107. A connecting rod 1010 is provided at the bottom of the main gear 102 between the first fan 108 and the second fan 109. The first gear 109 is installed on the surface of the connecting rod 1010. 11. The surfaces of the first fan 108 and the second fan 109 are provided with second gears 1012. The hydraulic drive motor 104, connected to an external power source, can drive the output end to rotate. The output end meshes with the main gear 102, which in turn drives the main gear 102 to rotate. When the main gear 102 rotates, it drives the connecting rod 1010 to rotate. When the connecting rod 1010 rotates, it drives the first gear 1011 to rotate. The first gear 1011 meshes with the second gear 1012 fixed to the first fan 108 and the second fan 109 respectively. When the main gear 102 rotates clockwise or counterclockwise, it can drive the first gear 1011 to rotate. The first gear 1011 drives the second gear 1012 to rotate, which in turn drives the first fan 108 and the second fan 109 to perform exhaust and intake operations through the first air duct 106 and the second air duct 107 opened in the conveying pipe 105. The first fan 108 and the second fan 109 can switch between intake and exhaust according to the rotation of the main gear 102, so as to dissipate internal heat and deliver external air for heat dissipation, thereby improving the service life of the device and reducing mechanical failures. The hydraulic drive motor 104 is a Bosch Rexroth A6VM walking motor.

[0024] The protective component 2 consists of a protective cover 201 and a brush 202. The protective cover 201 is installed at the top of the base 101, and the brush 202 is installed on the surface of the protective cover 201. The protective cover 201 is installed in a conical shape with a sloping surface. When stones pass through the brush 202 and come into contact with the protective cover 201, they can slide off the surface of the protective cover 201 and will not enter the interior of the base 101. The installation of the brush 202 serves as the first layer of barrier to block most of the dirt. During cleaning, a water gun is used to clean the dirt on the surface of the brush 202 and the stones on the surface of the protective cover 201, thereby protecting the main gear 102.

[0025] An oil tank 3 is provided on the inner wall of the base 101 on one side of the hydraulic drive motor 104. A transmission pipe 4 is installed on one side of the oil tank 3. The oil tank 3 is connected to the hydraulic drive motor 104 through the transmission pipe 4. The oil tank 3 is used to add hydraulic oil. The hydraulic oil can be transported to the hydraulic drive motor 104 through the transmission pipe 4 to drive the main gear 102 to rotate.

[0026] The second gear 1012 has the same size as the first gear 1011. The second gear 1012 meshes with the first gear 1011. The rotation of the first gear 1011 can drive the second gear 1012 to rotate clockwise and counterclockwise, thereby driving the first fan 108 and the second fan 109 to rotate and dissipate heat. This eliminates the need to use the power supply of the wheel excavator, reducing energy consumption.

[0027] The output end of the hydraulic drive motor 104 is meshed with the main gear 102. The inner bottom wall of the main gear 102 is equipped with a drive rod 5. The drive rod 5 is installed to connect with the cab and can drive the drive rod 5 to rotate and steer the cab when the main gear 102 rotates.

[0028] The base 101 has air inlet slots on its side, which are arranged at equal intervals. The air inlet slots can work with the heat dissipation component 1 to dissipate heat from the inside, forming a convection channel and accelerating the flow of air.

[0029] The top of the base 101 has a circular groove on the inner wall of the protective cover 201. The circular groove is located on the surface of the drive rod 5 and is used to limit the drive rod 5.

[0030] In this invention, the working steps of the device are as follows:

[0031] First step: The hydraulic drive motor 104, connected to an external power source, can drive the output end to rotate. The output end meshes with the main gear 102, which in turn drives the main gear 102 to rotate. When the main gear 102 rotates, it drives the connecting rod 1010 to rotate. When the connecting rod 1010 rotates, it drives the first gear 1011 to rotate. The first gear 1011 meshes with the second gear 1012 fixed to the first fan 108 and the second fan 109. When the main gear 102 rotates clockwise or counterclockwise, the first gear 1011 drives the second gear 1012 to rotate, which in turn drives the first fan 108 and the second fan 109 to perform exhaust and intake operations through the first air duct 106 and the second air duct 107 opened in the conveying pipe 105. The first fan 108 and the second fan 109 can switch between intake and exhaust according to the rotation of the main gear 102, thereby dissipating internal heat and delivering external air for heat dissipation, thus extending the service life of the device and reducing mechanical failures.

[0032] The second step: The protective cover 201 is installed in a conical shape with a sloping surface. When stones pass through the brush 202 and come into contact with the protective cover 201, they can slide off the surface of the protective cover 201 and will not enter the base 101. The installation of the brush 202 serves as the first layer of barrier to block most of the dirt. During cleaning, a water gun is used to clean the dirt on the surface of the brush 202 and the stones on the surface of the protective cover 201, thereby protecting the main gear 102.

[0033] The third step: The oil tank 3 is used to add hydraulic oil. The hydraulic oil can be transported to the hydraulic drive motor 104 through the transmission pipe 4 to drive the main gear 102 to rotate. The drive rod 5 is installed to connect with the cab. When the main gear 102 rotates, it can drive the drive rod 5 to rotate and steer the cab. The air inlet can work with the heat dissipation component 1 to dissipate heat inside and form a convection channel to accelerate the flow of air.
