Description

Technical Field

[0001] This utility model relates to the field of belt conveyors, and in particular to a self-moving and circumferential telescopic belt conveyor with a liftable tail. Background Technology

[0002] Most existing mobile telescopic belt conveyors are passively traction-driven, and currently mobile belt conveyors on the market can only move back and forth, resulting in low efficiency in relocation and low space utilization, making them inconvenient to work in narrow spaces. Moreover, traditional heavy-duty mobile belt conveyors require a large space due to their large turning radius, and suffer from poor mobility, poor self-movement displacement, and poor repeatability accuracy.

[0003] When loading ships on narrow piers in ports and stacking and placing materials in cargo yards, existing self-moving telescopic belt conveyors do not have a mechanical swing function. The swing function is based on a virtual theoretical swing center point. Ground and tire friction factors can affect the position of the swing center point, causing the swing center point to shift and the material drop point of the conveyor to shift. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a tail-liftable, self-moving, and circumferential telescopic belt conveyor.

[0005] To achieve the above objectives, this utility model is implemented according to the following technical solution:

[0006] A tail-mounted, self-moving, and circumferential telescopic belt conveyor includes a frame-type axle frame. A telescopic belt conveyor is mounted on top of the frame-type axle frame. A first hydraulic cylinder is mounted on the front end of the frame-type axle frame via a hinged seat. The end of the push rod of the first hydraulic cylinder is hinged to the middle of the telescopic belt conveyor via the hinged seat. A head support structure is fixed to the front end of the frame-type axle frame. Head wheels, a head driving mechanism, and a steering drive mechanism for driving the head wheels to rotate 360° are mounted at both ends of the head support structure. An anti-tilt and slewing support seat is mounted at the bottom of the rear end of the frame-type axle frame. A tail box girder bridge-type support structure is fixed to the bottom of the rear end of the frame-type axle frame at the front end of the anti-tilt and slewing support seat. The rear box girder bridge-type load-bearing structure frame is equipped with tail travel wheels, a tail travel drive mechanism, a steering drive mechanism for driving the tail travel wheels to rotate 360°, and a lifting mechanism for driving the tail travel wheels to rise and fall. The steering drive mechanism for driving the tail travel wheels to rotate 360° is located on both sides of the tail box girder bridge-type load-bearing structure frame. The tail travel wheels are rotatably installed in the mounting frame. The tail travel drive mechanism is fixedly installed on the mounting frame and connected to the tail travel wheels. The mounting frame is connected to the output end of the steering drive mechanism for driving the tail travel wheels to rotate 360° via an L-shaped frame. When the lifting mechanism drives the tail travel wheels to support the ground, the anti-tilt slewing support seat is suspended in the air. When the lifting mechanism drives the tail travel wheels to lift off the ground, the anti-tilt slewing support seat is supported on the ground.

[0007] Furthermore, the lifting mechanism includes a second hydraulic cylinder, the base of which is hinged to the lower end of the L-shaped frame, and the end of the push rod of which is hinged to the mounting frame. One end of the mounting frame is hinged to the end of the L-shaped frame.

[0008] Furthermore, the anti-tilt slewing support includes a base, a slewing support is installed inside the base, a hinge seat is rotatably installed inside the slewing support, a rotating shaft is provided inside the hinge seat, and two mounting blocks are rotatably connected to the rotating shaft at the same time. The end of one mounting block is fixedly connected to the tail of the frame-type vehicle bridge, and the end of the other mounting block is fixedly connected to the tail of the frame of the telescopic belt conveyor.

[0009] Compared with existing technologies, the new utility model of a swing-around and self-lateral telescopic belt conveyor is mainly suitable for loading ships and stacking and laying materials in narrow port piers. The addition of a liftable universal drive mechanism at the tail allows it to be raised independently when not in use, so that the self-balancing anti-tilt rotation device at the tail can be placed on the ground to achieve the rotation function. During operation, it can rotate and move flexibly around any point as the center, and can load ships on both sides of the pier and move warehouses to load ships on its own. It is more flexible and convenient than existing mobile belt conveyors, avoiding the occupation of a lot of space, time, manpower and material resources due to turning and other reasons, and effectively improving the available space and efficiency.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model.

[0015] like Figure 1 Figure 4As shown in the illustration, this embodiment exemplarily demonstrates a tail-mounted, self-moving, and circumferentially swinging telescopic belt conveyor, including a frame-type axle frame 1. A telescopic belt conveyor 2 is mounted on top of the frame-type axle frame 1. A first hydraulic cylinder 3 is mounted on the front end of the frame-type axle frame 1 via a hinged seat. The end of the push rod of the first hydraulic cylinder 3 is hinged to the middle of the telescopic belt conveyor 2 via the hinged seat. A head support structure is fixed to the front end of the frame-type axle frame 1. Head wheels, a head driving mechanism, and a steering drive mechanism for driving the head wheels to rotate 360° are mounted on both ends of the head support structure. It should be noted that in this embodiment... The head walking wheels, head walking drive mechanism, and steering drive mechanism for driving the head walking wheels to rotate 360° directly adopt the structure from our previously filed patent. The specific structure will not be described in detail in this embodiment (see application number CN202310564917.3, patent title: A Self-Rotating, Telescopic, and Tilting Belt Conveyor). Its main function is to achieve self-propelled movement and 360° steering of the head walking wheels. An anti-tilt rotation support seat 5 is installed at the bottom rear end of the frame-type axle frame 1. A tail box girder bridge-type load-bearing structure frame 6 is fixed to the bottom rear end of the frame-type axle frame 1 at the front end of the anti-tilt rotation support seat 5. The support frame 6 has a rear walking wheel 7, a rear walking drive mechanism 9, a steering drive mechanism 11 for driving the rear walking wheel to rotate 360°, and a lifting mechanism 12 for driving the rear walking wheel to rise and fall (the difference from the steering drive mechanism for driving the head walking wheel to rotate 360° is mainly that the drive motor is mounted on the upper part). In this embodiment, the structure of the rear walking wheel 7, the rear walking drive mechanism 9, and the steering drive mechanism 11 for driving the rear walking wheel to rotate 360° is the same as that of the head walking wheel, the head walking drive mechanism, and the steering drive mechanism for driving the head walking wheel to rotate 360°, and is used to drive the rear walking wheel. The steering drive mechanism 11, which allows the tail wheel to rotate 360°, is located on both sides of the tail box girder bridge-type load-bearing structure frame 6. Its main function is to enable the tail wheel to move on its own and to turn 360°. The tail wheel is rotatably mounted in the mounting frame 8. The tail drive mechanism 9 is fixedly mounted on the mounting frame 8 and connected to the tail wheel 7. The mounting frame 8 is connected to the output end of the steering drive mechanism 11, which is used to drive the tail wheel to rotate 360°, through the L-shaped frame 10. When the lifting mechanism 12 drives the tail wheel 7 to support the ground, the anti-tilt slewing support 5 is suspended in the air. When the lifting mechanism 12 drives the tail wheel 7 to leave the ground, the anti-tilt slewing support 5 supports the ground.

[0016] like Figure 2 , Figure 3 As shown, the lifting mechanism 12 includes a second hydraulic cylinder. The base of the second hydraulic cylinder is hinged to the lower end of the L-shaped frame 10, and the end of the push rod of the second hydraulic cylinder is hinged to the mounting frame 8. One end of the mounting frame 8 is hinged to the end of the L-shaped frame 10.

[0017] like Figure 4As shown, the anti-tilt slewing support 5 includes a base 51, in which a slewing support is installed. A hinge seat 52 is rotatably installed in the slewing support. A rotating shaft 53 is provided in the hinge seat 52. Two mounting blocks are rotatably connected to the rotating shaft 53. The end of one mounting block 54 is fixedly connected to the tail of the frame-type vehicle bridge 1, and the end of the other mounting block 55 is fixedly connected to the tail of the frame of the telescopic belt conveyor 2. This enables the entire telescopic belt conveyor to achieve self-balancing and anti-tilt, while also realizing the slewing function.

[0018] For example, the tail-mounted liftable self-moving and circumferential telescopic belt conveyor of this embodiment is used for loading ships on narrow piers in ports and for stacking and laying materials in cargo yards. The entire conveyor is moved by driving the head and tail wheels. When the conveyor needs to move, the tail drive device uses a hydraulic cylinder to make the tires support the ground, the anti-tilt slewing support seat lift off the ground, and the head and tail wheels are on the ground, allowing for lateral, longitudinal, diagonal, and slewing movements. When the conveyor needs to circumferentially lay materials, the tail drive device uses a hydraulic cylinder to make the tail wheels lift off the ground, the anti-tilt slewing support seat supports the ground, and the anti-tilt slewing support seat and the head wheels are on the ground. The steering drive mechanism of the head wheels can then turn the conveyor to circumferentially move around the anti-tilt slewing support seat.

[0019] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
