Description

Technical Field

[0001] The invention relates to the technical field of carrying platforms, in particular to a novel welded railway rail carrying lifting platform. Background Art

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

[0003] While traditional rail transport can travel in a straight line along the track (the shortest route), transport tools such as rail flatcars are limited in functionality and can only operate on fixed tracks. They cannot move independently from the track to the rail welding machine's storage point or maintenance starting point. This means that the rail welding machine must first be hoisted from the storage area to the trackside using other equipment (such as a truck crane or forklift), 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 scenarios where there is no auxiliary lifting equipment in the field, construction can easily be delayed due to poor connections. In addition, the rail vehicle requires additional traction when facing steep slopes.

[0004] Although vehicle transportation (mainly tracked vehicles) can adapt to complex terrain in non-track areas (such as dirt roads and grasslands), it is limited by its driving method and cannot directly drive along tracks, which greatly increases the transportation distance.

[0005] Therefore, the industry urgently needs an integrated transport platform that has off-road capability, rail driving 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 object of the present invention is to provide a novel welded railway rail carrying lifting platform to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a novel welding railway rail carrying and lifting platform, comprising a frame body, crawler bodies mounted on both sides of the bottom of the frame body, a track travel mechanism for traveling on the track mounted on the bottom of the frame body, and a crane mounted on the top of the frame body for hoisting a rail welding machine;

[0008] Two mechanical arms of auxiliary climbing and stabilizing equipment are symmetrically installed at the front end of the frame body. Both of the mechanical arms are equipped with gripping cones that can be inserted into the ground. A central jacking mechanism for assisting equipment to enter the track is installed at the bottom center of the frame body.

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

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

[0011] Preferably, an outer cylinder is installed on the support seat, and the outer cylinder is sleeved on the outer side of the jacking hydraulic cylinder.

[0012] Preferably, the mechanical arm comprises a movable arm; one end of the movable arm is rotatably connected with a taper arm, and a first hydraulic cylinder for driving the taper arm to operate is installed on the movable arm.

[0013] Preferably, a gripping taper is installed at the end of the movable arm, and a second hydraulic cylinder for driving the gripping taper to operate is installed on the movable arm.

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

[0015] Compared with the prior art, the beneficial effects of the present application are that the front-end symmetrical mechanical arms and gripping tapers can insert into the ground to form temporary support points on a slope less than 40° or a muddy road section, and the equipment is moved steadily through the pulling force or pushing force of the mechanical arms, thereby reducing the dependence on additional traction equipment. The bottom track walking mechanism can control the track wheel to be connected with the track through the pressing hydraulic cylinder, realize the quick switching from cross-country travel of the track to straight-line travel of the track, and greatly reduce the transportation time and energy consumption.

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

[0023] See also Figure 1-5 The present invention provides a technical solution: a new type of welding railway rail carrying and lifting platform, comprising a frame body 1, characterized in that: crawler bodies 2 are installed on both sides of the bottom of the frame body 1, a track running mechanism 8 for traveling on the track is installed at the bottom of the frame body 1, and a crane 5 for hoisting a rail welding machine is installed on the top of the frame body 1;

[0024] Two mechanical arms 6 for assisting climbing and stabilizing equipment are symmetrically installed at the front end of the frame body 1. Both mechanical arms 6 are equipped with gripping cones 7 that can be inserted into the ground. A central jacking mechanism 3 for assisting equipment to enter the track is installed at the bottom center of the frame body 1.

[0025] like Figure 4 As shown: the central jacking mechanism 3 includes a jacking hydraulic cylinder 31; one end of the cylinder body of the jacking hydraulic cylinder 31 is detachably connected to the bottom center of the frame body 1 through a flange, the end of the piston rod of the jacking hydraulic cylinder 31 is equipped with a ball head, and a ball socket is provided on the support seat 33. The end of the piston rod is movably connected to the support seat 33, and a slewing support 34 is installed on the outer side of the support seat 33. A base 35 is installed on the outer side 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 seat 33, and the outer cylinder 32 is sleeved on the outside of the jacking hydraulic cylinder 31. The outer cylinder 32 is a seamless steel pipe sleeved on the outside of the jacking hydraulic cylinder 31, thereby protecting the jacking hydraulic cylinder 31 and preventing debris from obstructing the operation of the jacking hydraulic cylinder 31.

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

[0028] As shown in Figure 5 The track running mechanism 8 includes a support rod 83, one end of the support rod 83 is rotationally connected to the vehicle frame body 1, the other end of the support rod 83 is provided with a track wheel 82, and a down-pressing hydraulic cylinder 81 is installed between the support rod 83 and the vehicle frame body 1. The support rod 83 can rotate around the rotation shaft by the extension and retraction of the piston rod of the down-pressing hydraulic cylinder 81, so that the track wheel 82 moves downward to contact the track.

[0029] Working principle: first, the operator starts the truck-mounted crane 5 through the control panel of the cab, uses the lifting function of the truck-mounted crane to accurately hoist the rail welding machine to the bearing surface of the vehicle frame body 1, and fixes the rail welding machine through the preset fixing device (such as buckle, hydraulic clamp) to prevent displacement due to bumping during transportation. At this time, the track running mechanism 8 is in the retracted state, the piston rod of the down-pressing hydraulic cylinder 81 is retracted, the support rod 83 is rotated upward, the track wheel 82 is separated from the ground, and the device is supported by the two side track bodies 2.

[0030] The device travels in the non-track area (such as wild field, construction road, etc.) through the track body 2. The track body adopts a wide track design to reduce the ground pressure ratio and is suitable for soft ground. When encountering complex terrain such as slope and mud, the operator can control the front end of the symmetrically distributed mechanical arm 6 to assist in passing.

[0031] When the device travels to the vicinity of the track and needs to switch to track travel, the operator controls the device to accurately move above the track through the cab to ensure that the center jacking mechanism 3 at the bottom of the vehicle frame body 1 is aligned with the middle part of the track.

[0032] The piston rod of the jacking hydraulic cylinder 31 is extended to push the support seat 33, the rotary support 34 and the base 35 to move downward until the anti-skid teeth at the bottom of the base 35 tightly contact the ground. Continuous jacking lifts the vehicle frame body 1 as a whole until the two side track bodies 2 completely separate from the ground. At this time, the weight of the device is borne by the center jacking mechanism and the two side mechanical arms, the ground penetration cone of the mechanical arm is inserted into the ground to assist in stability and prevent tilting.

[0033] In the track-off state, the operator controls the track running mechanism 8 to work, the piston rod of the down-pressing hydraulic cylinder 81 is extended to push the support rod 83 to rotate downward around the hinge point of the vehicle 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 amount of the down-pressing hydraulic cylinder is adjusted to ensure that the track wheel is accurately matched with the track.

[0034] After the switching is completed, the central jacking mechanism is retracted, and the device relies on the track wheels 82 to travel along the track, reducing the detour problem and shortening the transportation distance. When the track has a slope of ≤ 40°, the mechanical arm plays a role again. The two side ground-holding cones 7 alternately insert into the ground beside the track. When one side is pulled out for movement, the other side remains inserted to provide support. Through the pulling force or pushing force of the mechanical arm, the device is assisted to travel along the slope, avoiding the track wheels from slipping and eliminating the need for additional traction equipment.

[0035] While embodiments of the present application have been shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the application. The scope of the application is defined by the appended claims and their equivalents.
