Description

Technical Field

[0001] The invention relates to the technical field of transport bracket devices, in particular to a novel cantilever bracket device. Background Art

[0002] The mining rubber-tyred vehicle is a new type of rubber-tyred vehicle system that adopts rubber-tyred running and guiding technology, has anti-vibration and anti-derailment functions, and is widely used in technical fields such as coal mining. During the construction and mining of coal mining, it is necessary to transport and move extra-long materials, which requires the installation of a cantilever bracket device.

[0003] The existing Chinese patent application with application publication number CN115515821A discloses a carrier transport system, including several wheels that allow the device to move; a receiving device designed to receive a motor vehicle so that the motor vehicle is transported by means of an autonomous transport device; a motor designed to drive at least one of the wheels; a steering device designed to steer at least one of the wheels; and an autonomous control device designed to control the motor and the steering device, and the autonomous control device is designed to allow the autonomous transport device to move autonomously; the invention, the carrier can be moved manually or towed by a conventional tractor within the perimeter of the loading or unloading area. When the carrier is ready to be transferred, any carrier in the carrier can travel and position the carrier itself under the carrier to move the carrier without waiting for a whole column of carriers to be loaded.

[0004] However, the bracket device has the following defects when used:

[0005] 1. When the existing bracket device is used to transport materials, it is impossible to determine the specific length of the materials. When supporting and transporting extra-long materials, the center of gravity of the extra-long materials is biased towards the hollow part at the rear. During the transportation process, the materials are easily dropped or collided with the rear pillar of the vehicle due to the vibration of the vehicle when it is moving. The safety of transporting extra-long materials is low;

[0006] 2. When the existing bracket device is used to transport materials, vibration and other problems are unavoidable because the material conveying operation is achieved by moving the vehicle. Therefore, it is necessary to detect the materials in the transportation process in a timely manner to ensure that the materials can be adjusted in time when they are offset to reduce the problems of material falling. However, in actual operation, when the above scheme is installed on the side of the material, it is easy to collide with the material, and the safety is low; when the detection equipment is installed at the bottom of the material, the hollow part above the detection equipment affects the effect of supporting the material.

At the same time, in the actual operation of the above scheme, one rotation of the drive motor can achieve a moving operation of twice the horizontal distance, maximizing the effect of supporting extra-long materials;

[0046] 2. In the new cantilever bracket device, when adjusting the position of the horizontal support plate to improve the stability of supporting and transporting overlong materials, the hollow part generated by the movement of the horizontal support plate can be supplemented by the lifting and lowering of the two extended support plates to keep the hollow part flush with the horizontal support plate, so as to improve the stability of supporting and transporting overlong materials without affecting the hollow part.

When the overlong materials shake or deviate, they can be corrected in time, further reducing the probability of overlong materials falling or colliding with vehicles during transportation;

[0047] 3. In the new cantilever bracket device, during the process of supporting and transporting extra-long materials, the vertical frames and the beam oblique supports on both sides of the top of the bracket seat form a triangle with the bracket seat. At this time, the design of the triangular structure can improve the load-bearing capacity of the bracket seat during installation and assembly, and improve the support capacity when supporting and transporting extra-long materials. At the same time, the middle support obliquely set at the bottom of the beam oblique support can support and protect the beam oblique support that supports the positioning bracket seat, reducing the problem of the beam oblique support breaking when supporting heavier and extra-long materials, and has high safety.

[0048] 4. In the new cantilever bracket device, when the support plate is extended to support the extra-long material on the top, the multiple connecting rods arranged at the bottom angle of the extended support plate can squeeze the support spring and cause the support spring to be compressed. At this time, the elasticity of the support spring can buffer and damp the vibration force generated when supporting the material, thereby ensuring the service life and stability when supporting the extra-long material.
