Description

Technical Field

[0001] This utility model relates to the field of auxiliary transportation equipment technology for mining equipment, and in particular to a braking device, specifically a special platform device for a roadheader flatbed truck. Background Technology

[0002] In underground coal mine operations, many projects require roadheaders for construction. With numerous underground work sites, roadheaders have become the mainstream product for tunnel construction. The continuous and extensive use of roadheaders, coupled with the harsh underground working environment, results in a high frequency of maintenance and repair. Because disassembling and repairing roadheaders underground is time-consuming and labor-intensive, and involves many precision components such as pipelines, and requires stringent environmental conditions, roadheaders must be transported to the surface by flatbed truck for maintenance.

[0003] Therefore, the roadheader needs to be frequently disassembled, transported, and reassembled. The roadheader relies on temporary ramps or simple ramps to be moved onto a roadheader trailer for transport. In actual construction, this presents several drawbacks: the platform has poor compatibility with the roadheader and its trailer, easily leading to jamming due to size mismatches; its load-bearing capacity is also unstable, easily deforming under the weight of the roadheader; furthermore, there is a lack of effective guiding and braking mechanisms, making the roadheader prone to deviation and slippage during movement and transport, posing significant safety hazards; moreover, the construction and dismantling of temporary ramps or simple ramps is time-consuming, severely impacting transport efficiency; and the overall movement of the roadheader places high demands on the strength of the loading and unloading sites.

[0004] In summary, the process of moving a roadheader onto its flatbed trailer is subject to harsh and limited application conditions, poses significant safety hazards, has low construction safety, and involves complex procedures. Therefore, it is necessary to develop a dedicated platform device for roadheader flatbed trailers to solve the problem of transporting goods between the roadheader flatbed trailer and the loading / unloading location due to the elevation difference. Utility Model Content

[0005] This utility model addresses the problems of poor adaptability, unstable load-bearing leading to deformation, time-consuming and labor-intensive setup and dismantling, and significant safety hazards associated with temporary ramps or simple planks used when transporting a roadheader on a trackless rubber-wheeled vehicle due to the elevation difference between the roadheader's flatbed truck and the loading / unloading location. The invention provides a dedicated platform device for roadheader flatbed trucks.

[0006] This utility model is achieved using the following technical solution: A dedicated platform device for a roadheader flatbed truck includes a platform body connected to the roadheader flatbed truck. One end of the platform body is provided with a hook that mates with a hook hole on the roadheader flatbed truck, and the hook is fitted with a threaded sleeve for locking. The other end of the platform body is equipped with an inclined transition plate. Support cylinders are installed at the four corners of the lower surface of the platform body via a hinge structure. Traveling wheels are installed at the four corners of the lower surface of the platform body inside the support cylinders via a folding hinge structure. The support cylinders and traveling wheels alternately support the platform body. Guide plates are installed on both sides of the upper surface of the platform body, and several brake strips are laid on the upper surface of the platform body.

[0007] During implementation, the platform body, which is connected to the roadheader trailer, is made of high-strength alloy steel and welded together. The bottom of the platform body is welded with reinforcing ribs to enhance the overall load-bearing capacity and meet the load-bearing requirements of various roadheaders, loaders and excavators. One end of the platform body is equipped with a hook that mates with the hook hole on the roadheader trolley, and the hook is equipped with a threaded sleeve to achieve locking. Specifically, the hook is U-shaped, the hook body end is hinged to the platform body, and the hook head end is equipped with an external thread that mates with the threaded sleeve. The hook head end passes through the hook hole on the roadheader trolley and is tightened by the threaded sleeve to prevent the platform from separating from the roadheader trolley during construction. An inclined transition plate is installed at the other end of the platform body. One end of the inclined transition plate is detachably installed at one end of the platform body, and the other end rests on the ground. Anti-slip brake strips are welded to the surface of the inclined transition plate. Support cylinders are installed at the four corners of the lower surface of the platform body via hinge structures. The maximum load of a single support cylinder is 60 tons. The cylinder body of the support cylinder is hinged to the lower surface of the platform body, and the rotation angle between the cylinder body and the platform body is within 30°. This is used to achieve tilt support of the platform body, which is convenient for docking with trackless rubber-wheeled multi-functional flatbed carts of different heights. At the same time, it can keep the platform level on uneven ground. The piston rod end of the support cylinder is replaced by the support of the traveling wheel. The support cylinder is connected to the cylinder installed under the platform body through oil pipes. The support cylinder is independently controlled by the control system. The control system adopts existing technology. By adjusting the height difference between the two pairs of support cylinders, the platform body can achieve tilt adjustment within 30°. The four corners of the lower surface of the platform body are equipped with traveling wheels through a folding hinge structure inside the support cylinder. The support cylinder and the traveling wheel take turns supporting each other, switching the working and moving modes of the platform. When the piston rod of the support cylinder is in the supporting state, the traveling wheel is folded under the platform body. Specifically, the center of the axle of the traveling wheel is connected to the wheel frame, and the top of the wheel frame is hinged to the mounting seat fixed on the lower surface of the platform body. A support rod is hinged to the lower surface of the platform body next to the mounting seat. The top of the support rod cooperates with the locking baffle fixed in the middle of the wheel frame to keep the wheel frame fixed. The lower surface of the platform body is equipped with wheel fixing hooks for hooking the wheel axles, which are used for folding and retracting the traveling wheels when the platform is working; Guide plates are installed on both sides of the upper surface of the platform body. The guide plates are installed vertically on both sides of the platform body to ensure that the roadheader travels in a straight line during transportation and avoids deviation and falling. Furthermore, the guide plates are installed on both sides of the upper surface of the platform body in an adjustable position, which is suitable for roadheaders of different specifications. The adjustment range is 600mm~3600mm. The adjustment method can be achieved by fixing telescopic fence frames on the upper surface of the platform body or by clipping them on both sides of the platform body. Wear-resistant liners are fixed on the inner side of the guide plates. The upper surface of the platform body is covered with several brake strips, and the upper surface of the platform body has brake strip grooves. The brake strips are fixed in the brake strip grooves, and the upper surface of the brake strips protrudes from the upper surface of the platform body. Specifically, the brake strips are made of high-friction rubber material and are embedded in the brake strip grooves through high-temperature bonding, and the brake strips protrude 20mm above the upper surface of the platform body. When the roadheader travels on the main platform, it can increase the friction between the roadheader and the tracks to achieve temporary braking and prevent slippage.

[0008] In use, move the platform to the rear of the roadheader's flatbed truck, activate the control system to operate the support cylinders, and slowly extend the piston rods of the support cylinders until the height of the platform body is consistent with the height of the roadheader's flatbed truck. The traveling wheels should be completely off the ground and folded away. Specifically, fold up the support rod to disengage it from the locking baffle, and rotate the rod downwards around the hinge point until it fits against the lower surface of the platform, releasing the wheel frame constraint. The wheel frame rotates around the mounting base as a fulcrum until the wheel axle hook is inside the wheel fixing hook, avoiding interference with the ground. Align one end of the hook on the platform body with the hook hole, insert the hook end into the hook hole of the flatbed truck, and install the threaded sleeve to achieve mechanical locking. Continue operating the control system to adjust the height difference between the two support cylinders, creating a smooth slope between the platform and the ground. Place the inclined transition plate naturally on the ground, ensuring the anti-slip brake strips on the plate are in complete contact with the ground.

[0009] The roadheader slowly travels along the inclined transition plate to the main platform. During the journey, the roadheader corrects its direction by referring to the guide plate. When the roadheader's tracks contact the platform surface, the rubber brake strips generate friction through the tracks to prevent slippage. When the roadheader has completely traveled onto the main platform, the control system finely adjusts the platform's tilt angle to facilitate a smooth transition of the roadheader to the flatbed truck.

[0010] After the roadheader has completely left the platform, disconnect it from the roadheader trailer, extend the support cylinder, and lower the travel wheels. Specifically, unlock the wheel axle, rotate the wheel frame downwards until the wheel frame droops, and engage the free end of the support rod with the locking baffle to keep the wheel frame stable. Then retract the support cylinder, and the travel wheels are supported on the ground.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a special platform device for roadheader trolleys; it can flexibly adapt to different models of roadheaders and roadheader trolleys, significantly improve versatility, stabilize control, ensure load-bearing safety, effectively prevent the roadheader from deviating during travel or transport, and greatly reduce safety risks. Furthermore, this invention can adapt to different site conditions, eliminating the need for temporary construction work, effectively shortening operation time and improving overall work efficiency; the device has high structural strength and wear resistance, long service life, and low maintenance costs.

[0017] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0018] A special platform device for roadheader flatbed trucks, such as Figures 1-4 As shown: The platform body 1 is connected to the roadheader trolley 8. The platform body 1 is made of high-strength alloy steel and has a rectangular frame structure with a length of 5m and a width of 3.6m. The platform body 1 is welded from high-strength alloy steel. The bottom of the platform body 1 is welded with reinforcing ribs, and the spacing between two adjacent reinforcing ribs is 0.5m to enhance the overall load-bearing capacity and meet the load-bearing requirements of various roadheaders, loaders and excavators. One end of the platform body 1 is provided with a hook 6 that mates with the hook 6 hole on the roadheader trolley 8, and the hook 6 is provided with a threaded sleeve 9 to achieve locking. Specifically, the hook 6 is U-shaped, the hook body end of the hook 6 is hinged to the platform body 1, and the hook head end of the hook 6 is provided with an external thread that mates with the threaded sleeve 9. The hook head end passes through the hook 6 hole on the roadheader trolley 8 and is tightened by the threaded sleeve 9 to prevent the platform from separating from the roadheader trolley 8 during construction. An inclined transition plate 5 is installed at the other end of the platform body 1. One end of the inclined transition plate 5 is detachably installed at one end of the platform body 1, and the other end rests on the ground. Anti-slip brake strips 10 are welded to the surface of the inclined transition plate 5. Support cylinders 4 are installed at the four corners of the lower surface of the platform body 1 via hinge structures. The maximum load of a single support cylinder 4 is 60 tons. The cylinder body of the support cylinder 4 is hinged to the lower surface of the platform body 1. The rotation angle between the cylinder body and the platform body 1 is within 30°. This is used to achieve tilt support for the platform body 1, which facilitates docking with trackless rubber-wheeled multi-functional flatbed carts of different heights. At the same time, it can keep the platform level on uneven ground. The piston rod end of the support cylinder 4 is replaced by the support of the traveling wheel 2. The support cylinder 4 is connected to the cylinder installed below the platform body 1 through an oil pipe. The support cylinder 4 is independently controlled by the control system 3. The control system 3 adopts existing technology. In this embodiment, the control system 3 extends a 5-meter-long rubber pipe from the cylinder to the control handle to remotely control the cylinder lifting rod to adjust the undulation angle of the platform. By adjusting the height difference between the two pairs of support cylinders 4, the platform body 1 can achieve tilt adjustment within 30°. At the four corners of the lower surface of the platform body 1, inside the support cylinder 4, there are traveling wheels 2 installed via a folding hinge structure. The wheel diameter is Φ300mm. The support cylinder 4 and the traveling wheels 2 are used as alternate supports to switch the working and moving modes of the platform. When the piston rod of the support cylinder 4 is in the support state, the traveling wheels 2 are folded under the platform body 1. Specifically, the axle 201 of the traveling wheel 2 is connected to the wheel frame 202 in the center, and the top of the wheel frame 202 is hinged to the mounting seat 203 fixed on the lower surface of the platform body 1. A support rod 204 is hinged to the lower surface of the platform body 1 next to the mounting base 203. The top of the support rod 204 cooperates with the locking baffle 205 fixed in the middle section of the wheel frame 202 to keep the wheel frame 202 fixed. The lower surface of the platform body 1 is provided with a wheel fixing hook 206 for hooking the wheel axle 201, which is used for folding and retracting the walking wheel 2 when the platform is working; Guide plates 7 are installed on both sides of the upper surface of the platform body 1. The guide plates 7 are vertically installed on both sides of the platform body 1 with a height of 300mm to ensure that the tunneling machine travels in a straight line during transportation and avoids deviation and falling. Wear-resistant liners are fixed on the inner side of the guide plates 7. The upper surface of the platform body 1 is covered with several brake strips 10, and the upper surface of the main platform has grooves for the brake strips 10. The brake strips 10 are fixed in the grooves, and the upper surface of the brake strips 10 protrudes from the upper surface of the main platform. Specifically, the brake strips 10 are made of high-friction rubber material and are embedded in the grooves by high-temperature bonding, and the brake strips 10 are 20mm higher than the upper surface of the platform body 1. When the roadheader travels on the main platform, the friction between the roadheader and the tracks can be increased to achieve temporary braking and prevent slippage.

[0019] When using it, take the EBZ-280 roadheader in the north wing auxiliary transport roadway of Huayang Group Qiyuan Company as an example for on-site maintenance: 1. Preparation stage Move the platform to the rear of the roadheader trolley 8, start the control system 3 to operate the support cylinder 4, so that the piston rod of the support cylinder 4 slowly extends, making the height of the platform body 1 the same as the height of the roadheader trolley 8, and the traveling wheels 2 completely leave the ground and fold up. At this time, the wheel axle 201 of the traveling wheels 2 is hooked in the wheel fixing hook 206 to avoid interference with the ground; one end of the hook 6 of the platform body 1 is aligned with the hook 6 hole. After inserting the hook end into the hook 6 hole of the trolley, install the threaded sleeve 9 to achieve mechanical locking.

[0020] Adjust the width of the platform transition device and the spacing of the guide plates 7 according to the model of the roadheader to ensure compatibility with the roadheader.

[0021] Continue operating the control system 3 to adjust the height difference between the two end support cylinders 4, so that the platform forms a smooth slope with the ground; place the inclined transition plate 5 naturally on the ground, ensuring that the anti-slip brake strip 10 on the plate surface is in complete contact with the ground.

[0022] 2. Platform Launch Phase Operate the roadheader to approach the platform and align its tracks with the platform transition device. With the reference guidance of the guide plate 7, the roadheader slowly moves along the inclined transition plate 5 to the platform body 1. When the roadheader tracks contact the platform surface, the rubber brake strips 10 generate friction through the track compression to achieve anti-slip.

[0023] 3. Transfer to the roadheader's flatbed truck (stage 8) Once the roadheader has fully moved onto the platform body 1 and its brakes are confirmed to be secure, the platform tilt angle is finely adjusted through the control system 3 to ensure that the platform and the roadheader trolley 8 are horizontally connected. Guided by the guide plate 7, the roadheader slowly moves off the platform and into the designated position on the roadheader trolley 8, thus smoothly transitioning the roadheader to the trolley.

[0024] 4. Reset Phase After the roadheader has completely left the platform, disconnect it from the roadheader trolley 8, extend the support cylinder 4, lower the traveling wheels 2, retract the support cylinder 4, and the traveling wheels 2 are supported on the ground. Move the platform to the storage position to complete one transfer operation.
