Description

Technical Field

[0001] This utility model relates to the field of transportation platform technology, specifically a novel welded railway rail transportation and lifting platform. Background Technology

[0002] In railway track welding and maintenance operations, the efficient transport of large equipment such as rail welding machines is a crucial link in ensuring construction progress. Current mainstream transportation methods in the industry have significant limitations, specifically in the following aspects:

[0003] While traditional rail transport methods allow for straight-line travel (the shortest path), transport vehicles like rail flatcars are limited in function, operating only on fixed tracks and unable to move independently to the storage or maintenance point of the rail welding machine. This means that the rail welding machine must first be hoisted from the storage area to the track using other equipment (such as truck cranes or forklifts), and then hoisted a second time onto the rail transport vehicle. The entire process involves multiple loading and unloading operations and equipment coordination, making it cumbersome and time-consuming. Especially in field scenarios without hoisting assistance, poor coordination can easily delay construction. Furthermore, the rail vehicle requires additional traction when facing steep inclines.

[0004] While vehicle-based transportation (primarily tracked vehicles) can adapt to complex terrain in off-track areas (such as dirt roads and grasslands), it is limited by its mode of transport and cannot travel directly along tracks, significantly increasing the transport distance.

[0005] Therefore, the industry urgently needs an integrated transportation platform that combines off-road capability, rail travel function, and stability in complex terrain to solve the pain points of traditional transportation methods, such as cumbersome processes, long routes, and poor adaptability. Summary of the Invention

[0006] The purpose of this utility model is to provide a novel welded railway rail transport and lifting platform to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel welding railway rail transport and lifting platform, comprising a frame body, track bodies installed on both sides of the bottom of the frame body, a track traveling mechanism for traveling on the track installed at the bottom of the frame body, and a crane mounted on the vehicle for lifting a rail welding machine installed at the top of the frame body;

[0008] Two robotic arms for assisting climbing and stabilizing are symmetrically installed at the front end of the main frame. Each robotic arm is equipped with a ground grip cone that can be inserted into the ground. A central lifting mechanism for assisting the equipment to enter the rail is installed at the bottom center of the main frame.

[0009] Preferably, the central lifting mechanism includes a lifting hydraulic cylinder; one end of the lifting hydraulic cylinder is connected to the bottom center of the vehicle frame body, and a support seat is installed at the end of the piston rod of the lifting hydraulic cylinder.

[0010] Preferably, a slewing support is installed on the outer side of the support base, and a base is installed on the outer side of the slewing support.

[0011] Preferably, an outer cylinder is installed on the support base, and the outer cylinder is sleeved on the outside of the lifting hydraulic cylinder.

[0012] Preferably, the robotic arm includes a movable arm; one end of the movable arm is rotatably connected to a conical arm, and a first hydraulic cylinder for driving the conical arm is mounted on the movable arm.

[0013] Preferably, a grip cone is installed at the end of the boom, and a second hydraulic cylinder for driving the grip cone is installed on the boom.

[0014] Preferably, the track walking mechanism includes a support rod; one end of the support rod is rotatably connected to the frame body, the other end of the support rod is equipped with a track wheel, and a downward hydraulic cylinder is installed between the support rod and the frame body.

[0015] Compared with existing technologies, the advantages of this invention are: the symmetrically distributed robotic arms and grip cones at the front end can insert into the ground to form temporary support points on slopes less than 40° or muddy sections, allowing for steady movement of the equipment through the pulling or pushing force of the robotic arms, reducing reliance on additional traction equipment. The bottom track-walking mechanism can control the track wheels to connect with the track through a downward-pressing hydraulic cylinder, enabling a rapid switch from tracked off-road travel to track-based straight-line travel, significantly reducing transportation time and energy consumption.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a novel welding railway rail transport lifting platform, including a frame body 1, characterized in that: track bodies 2 are installed on both sides of the bottom of the frame body 1, a track traveling mechanism 8 for traveling on the track is installed at the bottom of the frame body 1, and a crane 5 for lifting the rail welding machine is installed on the top of the frame body 1.

[0024] Two robotic arms 6 for assisting in climbing and stabilizing are symmetrically installed at the front end of the main frame 1. Each robotic arm 6 is equipped with a ground-gripping cone 7 that can be inserted into the ground. A central lifting mechanism 3 for assisting the equipment to enter the rail is installed at the bottom center of the main frame 1.

[0025] like Figure 4 As shown: The central lifting mechanism 3 includes a lifting hydraulic cylinder 31; one end of the cylinder body of the lifting hydraulic cylinder 31 is detachably connected to the bottom center of the frame body 1 through a flange; the piston rod end of the lifting hydraulic cylinder 31 is equipped with a ball head; the support seat 33 is provided with a ball socket; the end of the piston rod and the support seat 33 are movably connected; a slewing support 34 is installed on the outside of the support seat 33; a base 35 is installed on the outside of the slewing support 34; and the bottom of the base 35 is provided with evenly distributed anti-slip teeth.

[0026] like Figure 4 As shown: An outer cylinder 32 is installed on the support base 33. The outer cylinder 32 is sleeved on the outside of the lifting hydraulic cylinder 31. The outer cylinder 32 is a seamless steel pipe sleeved on the outside of the lifting hydraulic cylinder 31, thereby protecting the lifting hydraulic cylinder 31 and preventing debris from obstructing the operation of the lifting hydraulic cylinder 31.

[0027] like Figure 3 As shown: The robotic arm 6 includes a movable arm 61; a conical arm 63 is rotatably connected to one end of the movable arm 61, and a first hydraulic cylinder 62 is mounted on the movable arm 61 to drive the conical arm 63. A gripping cone 7 is mounted at the end of the movable arm 61, and a second hydraulic cylinder 64 is mounted on the movable arm 61 to drive the gripping cone 7. The movable arm 61 and the conical arm 63 cooperate to move the gripping cone 7.

[0028] like Figure 5 As shown: The track-walking mechanism 8 includes a support rod 83; one end of the support rod 83 is rotatably connected to the frame body 1, and the other end of the support rod 83 is equipped with a track wheel 82. A downward hydraulic cylinder 81 is installed between the support rod 83 and the frame body 1. By extending and retracting the piston rod of the downward hydraulic cylinder 81, the support rod 83 can rotate around the pivot, thereby causing the track wheel 82 to move downward and contact the track.

[0029] Working principle: First, the operator starts the truck-mounted crane 5 through the control panel in the cab. Using the crane's lifting function, the rail welding machine is precisely lifted onto the bearing surface of the chassis body 1. The machine is then securely fixed using pre-set fixing devices (such as clips and hydraulic clamps) to prevent displacement due to bumps during transport. At this time, the rail travel mechanism 8 is in the retracted state, the piston rod of the hydraulic cylinder 81 retracts, driving the support rod 83 to rotate upward, and the rail wheels 82 lift off the ground. The equipment is then supported by the track bodies 2 on both sides of the bottom.

[0030] The equipment travels in off-track areas (such as field sites, construction access roads, etc.) via the tracked main body 2. The tracked main body adopts a wide track design to reduce ground pressure and is suitable for soft ground. When encountering complex terrain such as slopes or mud, the operator can use the symmetrically distributed robotic arms 6 at the front to assist in passage.

[0031] When the equipment needs to switch to track travel when it is near the track, the operator controls the equipment through the cab to move it precisely above the track, ensuring that the center lifting mechanism 3 at the bottom of the frame body 1 is aligned with the center of the track.

[0032] The piston rod of the lifting hydraulic cylinder 31 extends, pushing the support seat 33, the slewing support 34 and the base 35 downward until the anti-slip teeth at the bottom of the base 35 are in close contact with the ground. The lifting continues to raise the frame body 1 as a whole until the track bodies 2 on both sides are completely off the ground. At this time, the weight of the equipment is borne by the central lifting mechanism and the two mechanical arms. The grip cones of the mechanical arms are inserted into the ground to assist in stabilization and prevent tilting.

[0033] With the tracks off the ground, the operator controls the track walking mechanism 8 to work. The piston rod of the hydraulic cylinder 81 extends, pushing the support rod 83 to rotate downward around the hinge point of the frame body, so that the track wheel 82 gradually approaches the track. After the track wheel 82 contacts the top surface of the track, the extension and retraction of the hydraulic cylinder is finely adjusted to ensure that the track wheel and the track are precisely matched.

[0034] After the switch is completed, the central lifting mechanism is retracted, and the equipment travels along the track using the track wheels 82, reducing detours and shortening the transportation distance. When the track has a slope of ≤40°, the robotic arm comes into play again. The two gripping cones 7 alternately insert into the ground next to the track. When one side is pulled out and moved, the other side remains inserted for support. The robotic arm's pulling or pushing force assists the equipment in traveling along the slope, preventing the track wheels from slipping and eliminating the need for additional traction equipment.

[0035] 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.
