Description

Technical Field

[0001] This utility model relates to the field of loader technology, and more specifically, to a low-profile electric remote-controlled tracked skid steer loader. Background Technology

[0002] Skid steer loaders, as a type of multi-functional and highly mobile engineering machinery, are widely used in construction, municipal engineering, agriculture, landscaping, warehousing and other fields. They achieve steering by differential speed of the left and right tracks (or tires), and have the advantages of turning on the spot, compact size and flexible operation. They can be equipped with a variety of attachments such as buckets, forks, breakers, and drilling machines to complete a variety of tasks such as excavation, loading, transportation and crushing.

[0003] With the development of modern industrial production and special operating environments, higher requirements have been placed on the adaptability of construction machinery to operating spaces. In some special scenarios with limited space height, such as underground pipe corridors, subway tunnels, civil defense projects, low-rise factories, equipment mezzanines, ship cabins, and dense rack warehouses, traditional skid steer loaders cannot enter or operate effectively due to their excessive overall height (especially the cab and boom lifting height), which seriously restricts the efficiency and safety of mechanized construction. Furthermore, the traditional drive method involves an engine or battery driving a hydraulic pump, which in turn drives a hydraulic motor through pipelines. The hydraulic motor then outputs power to drive the entire vehicle. The hydraulic pump also drives the boom cylinder and dump cylinder through hydraulic pipelines and operating valves. The drawback of this working principle is that the pump motor and hydraulic pump need to work continuously whether the vehicle is moving or working, which can lead to overheating of the pump motor, triggering the protection mechanism, and causing the vehicle to stop working, thus shortening the working time and reducing work efficiency.

[0004] In view of this, this paper studies and improves upon the existing problems, and provides a low-profile electric remote-controlled tracked skid steer loader. The aim is to solve the problems and improve its practical value through this technology. Utility Model Content

[0005] The purpose of this utility model is to provide a low-profile electric remote-controlled tracked skid steer loader to solve the problems and deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a low-profile electric remote-controlled tracked skid steer loader, which is achieved through the following specific technical means: A low-profile electric remote-controlled tracked skid steer loader includes: a body, a boom, a boom cylinder, a quick-change bracket, a bucket, a tipping cylinder, a battery, a traveling mechanism, a hydraulic drive mechanism, and a remote control receiver; the boom is rotatably mounted on the body; one end of the boom cylinder is rotatably mounted on the body, and the other end of the boom cylinder is rotatably mounted on the boom; the quick-change bracket is fixedly mounted on the end of the boom away from the body; the bucket is detachably fixedly connected to the quick-change bracket; one end of the tipping cylinder is rotatably mounted on the boom, and the other end of the tipping cylinder is rotatably mounted on the bucket; the battery is fixedly mounted inside the body. The walking mechanism includes a walking motor, tracks, and a walking controller. The walking motor is fixedly mounted on the machine body and is electrically connected to the battery. The tracks are located at both ends of the machine body, and the walking motor drives the tracks to rotate. The walking controller is fixedly mounted on the machine body and is electrically connected to the walking motor. The hydraulic drive mechanism drives the boom cylinder and the bucket cylinder to extend and retract; The remote control receiver is fixedly mounted on the machine body.

[0007] As a further optimization of this technical solution, the hydraulic drive mechanism of the low-profile electric remote-controlled tracked skid steer loader of this utility model includes a hydraulic oil tank, a hydraulic oil pump, an oil pump motor, and a hydraulic oil radiator. The hydraulic oil tank is fixedly mounted on the machine body; the hydraulic oil pump is fixedly mounted on the machine body, and the hydraulic oil pump, hydraulic oil tank, boom cylinder, and dump cylinder are connected by pipes; the oil pump motor is fixedly mounted on the hydraulic oil pump; the hydraulic oil radiator is fixedly mounted on the machine body, and the hydraulic oil radiator is used for heat dissipation and cooling of the pipes between the hydraulic oil pump, hydraulic oil tank, boom cylinder, and dump cylinder.

[0008] As a further optimization of this technical solution, the present invention provides a low-profile electric remote-controlled tracked skid loader, which also includes a top cover, which is fixedly installed on the top side of the machine body.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: 1. This utility model sets up a walking mechanism and a hydraulic drive mechanism on the machine body. The walking motor is directly driven by the battery through the walking controller to control the movement of the vehicle. The tipping cylinder and boom cylinder are controlled and adjusted by the oil pump motor and hydraulic oil pump through hydraulic pipelines. In this way, two systems are set up for walking and working. When the vehicle is walking, the oil pump motor is in a stopped state. The oil pump motor will only work when adjusting the tipping cylinder and boom cylinder. This can reduce the working time of the oil pump motor, avoid the occurrence of high temperature, and thus extend the working life of the oil pump motor. It also increases the vehicle's operating time, thereby improving work efficiency.

[0010] 2. This utility model has a remote control receiver installed on the machine body, which can realize the operation of the whole machine through electric remote control. Moreover, the whole machine is small in size and equipped with a walking motor and tracks, which can enter special environments such as narrow spaces, complex terrain, poor air circulation, and dangerous working environments. This improves work efficiency, expands the adaptability of working environment, reduces work risks, and also reduces noise.

[0011] 3. This utility model improves the loader and has the advantages of reasonable structural design, divided into two systems: walking and working. This avoids high temperature phenomenon of oil pump motor, increases the vehicle's operating time, expands the adaptability of working environment, reduces working risk, and improves work efficiency, thereby effectively solving the problems and shortcomings of existing technology and equipment.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for a low-profile electric remote-controlled tracked skid steer loader: A low-profile electric remote-controlled tracked skid steer loader includes: a body 1, a boom 2, a boom cylinder 3, a quick-change bracket 4, a bucket 5, a tipping cylinder 6, a battery 7, a walking mechanism 8, a hydraulic drive mechanism 9, a remote control receiver 10, and a top cover 11.

[0016] The boom 2 is used to lift the bucket 5, and the boom 2 is rotatably mounted on the machine body 1.

[0017] The boom cylinder 3 is used to drive the boom 2 to rise and fall. One end of the boom cylinder 3 is rotatably mounted on the machine body 1, and the other end of the boom cylinder 3 is rotatably mounted on the boom 2. When the boom cylinder 3 extends, it pushes the boom 2 to rise. When the boom cylinder 3 retracts, it drives the boom 2 to fall.

[0018] The quick-change bracket 4 is fixedly installed at the end of the boom 2 away from the body 1, which can enable quick disassembly and assembly of the bucket 5 or other auxiliary tools.

[0019] The bucket 5 is used to load materials. The bucket 5 is fixedly connected to the quick-change bracket 4 in a detachable manner. The bucket 5 can also be replaced with other auxiliary tools according to work requirements.

[0020] The tipping cylinder 6 is used to drive the bucket 5 to tilt. One end of the tipping cylinder 6 is rotatably mounted on the boom 2, and the other end of the tipping cylinder 6 is rotatably mounted on the bucket 5. When the tipping cylinder 6 extends, it drives the bucket 5 to tilt downward. When the tipping cylinder 6 retracts, it drives the bucket 5 to tilt upward.

[0021] Battery 7 is fixedly installed inside the body 1 to provide power support for the operation of the whole machine. It can also be replaced with lead-acid or lithium batteries according to actual needs. Moreover, the use of new energy batteries as power source avoids exhaust emissions and reduces working noise.

[0022] The walking mechanism 8 is used to drive the overall movement. The walking mechanism 8 includes a walking motor 81, a track 82, and a walking controller 83. The walking motor 81 is fixedly mounted on the machine body 1 and is electrically connected to the battery 7. The track 82 is located at both ends of the machine body 1, and the walking motor 81 drives the track 82 to rotate. The walking controller 83 is fixedly mounted on the machine body 1 and is electrically connected to the walking motor 81. The walking motor 81 directly drives the track 82, and there is no need to rely on the oil pump motor 93 when walking, thus reducing the burden on the oil pump motor 93.

[0023] The hydraulic drive mechanism 9 is used to drive the boom cylinder 3 and the bucket cylinder 6 to extend and retract. The hydraulic drive mechanism 9 includes a hydraulic oil tank 91, a hydraulic oil pump 92, an oil pump motor 93, and a hydraulic oil radiator 94. The hydraulic oil tank 91 is fixedly mounted on the machine body 1. The hydraulic oil pump 92 is fixedly mounted on the machine body 1, and the hydraulic oil pump 92, the hydraulic oil tank 91, the boom cylinder 3, and the bucket cylinder 6 are connected by pipes. The oil pump motor 93 is fixedly mounted on the hydraulic oil pump 92. The hydraulic oil radiator 94 is fixedly mounted on the machine body 1, and the hydraulic oil radiator 94 is used for heat dissipation and cooling of the pipes between the hydraulic oil pump 92, the hydraulic oil tank 91, the boom cylinder 3, and the bucket cylinder 6.

[0024] The remote control receiver 10 is fixedly mounted on the main body 1. Electronic cameras are equipped on both the front and back of the main body 1. The remote control is equipped with a display screen and is connected to the remote control receiver 10. It can intuitively see the surrounding working conditions and remotely control the equipment to enter special environments such as confined spaces, complex terrains, poor air circulation, and dangerous working environments. This improves work efficiency, expands the adaptability of the working environment, and reduces work risks.

[0025] The top cover 11 is used to close the body 1, and the top cover 11 is fixedly installed on the top side of the body 1.

[0026] Working principle: In use, the device can be controlled by a remote control. When the device moves, the walking motor 81 drives the track 82 to rotate to achieve movement. When turning is required, one track 82 is kept stationary while the other track 82 rotates to complete the turn. The bucket 5 is controlled by the boom cylinder 3 and the tipping cylinder 6. The oil pump motor 93 and the hydraulic oil pump 92 work together to generate the pressure required by the hydraulic system and deliver hydraulic oil to the system (boom cylinder 3 and tipping cylinder 6), thereby enabling the bucket 5 to complete lifting and tipping, so that the device can work normally.

[0027] In summary, this low-profile electric remote-controlled tracked skid steer loader, by incorporating a walking mechanism and a hydraulic drive mechanism on its body, uses a battery to directly drive the walking motor via a walking controller to control the vehicle's movement. The dump cylinder and boom cylinder are controlled and adjusted by an oil pump motor and a hydraulic pump via hydraulic lines. This separates the walking and working systems, ensuring that the oil pump motor is inactive when the vehicle is moving, only activating when adjusting the dump cylinder and boom cylinder. This reduces the oil pump motor's operating time, avoids overheating, extends its lifespan, and increases the vehicle's operating time, thereby improving work efficiency. Furthermore, by integrating the machine body... Equipped with a remote control receiver, the machine can be controlled electrically. Its compact size, combined with a walking motor and tracks, allows it to operate in confined spaces, complex terrains, poorly ventilated areas, and hazardous environments, improving work efficiency, expanding its adaptability, reducing work risks, and minimizing noise. Through improvements to the loader, it features a rational structural design, separating the walking and working systems to avoid overheating of the hydraulic pump motor, increasing the vehicle's operating time, expanding its adaptability to different working environments, reducing work risks, and improving work efficiency. This effectively solves the problems and shortcomings of existing technologies and equipment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
