Description

Technical Field

[0001] This invention belongs to the field of auxiliary operation machinery in coal mines, specifically relating to a tracked tractor-trailer type heavy-duty anti-impact support transport vehicle. Background Technology

[0002] To strengthen the roof support in the advance area during the longwall mining process, mines in China with rockburst potential commonly use anti-rockburst supports (anti-rockburst hydraulic supports) for advance support in the two roadways of longwall mining faces, thereby improving the roadway support strength. Currently used anti-rockburst supports mostly employ a four-column support structure, which is significantly greater than ordinary single or unit-type hydraulic supports in terms of support resistance and weight, typically weighing around 20 tons. After the anti-rockburst supports are installed in the roadway, the passageway narrows to only 2.1-2.3 meters wide. Heavy-duty transport vehicles commonly used underground generally have four wheels and a width exceeding 2 meters, making it impossible for such transport equipment to operate within the passageway.

[0003] Currently, the alternating forward movement of anti-impact supports during construction is mainly done manually, using manual track laying and winch wire rope traction. This method is inefficient, labor-intensive, and physically demanding. During the advancement of the work face, the winch needs to be repeatedly moved and fixed, making the process complex and tedious. Furthermore, the winch wire rope traction has a high risk of accidents and a slow moving speed. To better solve the problem of moving anti-impact supports, there is an urgent need to research and develop mechanized handling equipment for anti-impact supports that can smoothly pass through narrow transport channels and has a large load capacity. Summary of the Invention

[0004] This invention aims to solve the problem of rapid moving and transporting of anti-impact supports in the confined space of the return air roadway in fully mechanized mining faces, realize the mechanized moving of large-tonnage anti-impact supports, reduce the labor intensity of workers, and improve the support efficiency of the return air roadway.

[0005] The present invention provides the following technical solution: a tracked tractor-trailer type heavy-duty anti-impact support transport vehicle, comprising a tractor and a flatbed trailer, wherein the tractor and the flatbed trailer are connected by a swing hinge frame. The flatbed trailer includes a carrying flatbed, which includes a front flat section, a rear flat section, and a middle sunken transport platform; the bottom of the front flat section is equipped with a front carrying wheel axle, and the bottom of the rear flat section is equipped with a rear carrying wheel axle. An auxiliary loading and unloading mechanism is provided on one side of the carrying plate, and a protective mechanism is provided on the other side. The auxiliary loading and unloading mechanism is used to drag the anti-impact support from the side to the sunken transport platform, or to drag it in the opposite direction to unload it. The protective mechanism works with the auxiliary loading and unloading mechanism to prevent the anti-impact support on the sunken transport platform from moving laterally.

[0006] Furthermore, the auxiliary loading and unloading mechanism includes two sets of horizontal pull cylinders and chains. The two sets of horizontal pull cylinders are respectively arranged on the vertical surfaces on both sides of the sunken transport platform. Each set of horizontal pull cylinders includes an upper horizontal pull cylinder and a lower horizontal pull cylinder arranged in parallel. The cylinder barrels of the upper and lower horizontal pull cylinders are movably nested in the guide holes of the bearing plate, and the piston rods are connected to the bearing plate by a pin. The piston rods of the upper horizontal pull cylinders face the right side of the bearing plate, and the piston rods of the lower horizontal pull cylinders face the left side of the bearing plate. The two sides of the chain can optionally be connected to the cylinder barrel ends of the two upper horizontal pull cylinders or the cylinder barrel ends of the two lower horizontal pull cylinders.

[0007] Furthermore, the swing articulated frame includes a front cross, a rear cross, a steering cylinder, a vertical hinge pin, and a cylinder pin; the front cross is hinged to the tractor via a front horizontal hinge pin, and the rear cross is hinged to the flatbed trailer via a rear horizontal hinge pin; the rotation axes of both the front and rear horizontal hinge pins are parallel to the ground; the front and rear crosses are hinged via vertical hinge pins; a steering cylinder is arranged on each side of the front and rear crosses, and the two ends of the steering cylinder are hinged to the front and rear crosses respectively via cylinder pins.

[0008] Furthermore, a spherical bearing is installed at the hinge pin to achieve universal hinge between the front cross and the rear cross; a spherical bearing is installed at the cylinder pin to achieve universal hinge between the steering cylinder and the front and rear crosses.

[0009] Furthermore, both the front and rear load-bearing wheel axles include tires, sliding sleeves, and sliding lifting axles; the sliding sleeve is slidably inserted into the sliding lifting axle, and the sliding key on the sliding sleeve cooperates with the keyway of the sliding lifting axle to restrict the rotation of the sliding sleeve; lifting cylinders are installed inside the sliding sleeve and the sliding lifting axle; the two ends of the sliding lifting axle are connected to tire brakes by bolts, and the tire brakes are connected to the tires by bolts. The top end of the sliding sleeve in the front load-bearing wheel axle is connected to the load-bearing plate by bolts; the top end of the sliding sleeve in the rear load-bearing wheel axle is provided with a hinge pin hole, the axis of the hinge pin hole is perpendicular to the axis of the tire of the rear load-bearing wheel axle, and the rear wheel axle swing pin is installed in the hinge pin hole and hinged to the load-bearing plate.

[0010] Furthermore, support columns are erected on the front and rear flat sections of the load-bearing plate, and the support columns are staggered with the front and rear load-bearing wheel axles, respectively.

[0011] Furthermore, the protective mechanism includes a sliding side guard plate, the two transverse plates of which are slidably connected to the bearing plate, and the longitudinal plate between the two transverse plates is intercepted between the front and rear flat sections of the bearing plate. A side guard plate telescopic cylinder is connected between the sliding side guard plate and the bearing plate.

[0012] Furthermore, a flat roller is installed on the sunken transport platform carrying the flat plate, and the axis of the flat roller is parallel to the longitudinal direction of the carrying plate; a flipping wedge is connected to one side edge of the sunken transport platform through a flipping wedge hinge shaft, the flipping wedge and the auxiliary loading and unloading mechanism are on the same side, and a flat roller is installed on the inclined surface of the flipping wedge.

[0014] Compared with the prior art, the advantages of the present invention are: The present invention provides a tracked towing flatbed trailer-type heavy-duty anti-impact bracket transport vehicle. The whole machine is designed as a combination of a towing vehicle and a flatbed trailer. The towing vehicle is driven by an engine and travels on tracks. It is designed with a narrow body structure to ensure passage space. The flatbed trailer adopts a passive towing type and only considers the function of loading and unloading anti-impact brackets. Its structural dimensions are narrower and its height is lower than that of the towing vehicle.

[0015] The tractor and flatbed trailer are connected by a swing-arm hinge, which is omnidirectionally adjustable and can be used in combination with follow-up towing and active steering, solving the problem of forward and backward steering of the entire machine. The flatbed trailer is specially designed with anti-impact brackets, making it easier to load, unload and move the anti-impact brackets. The load-bearing flatbed is lowered when loading and raised when transporting, balancing loading convenience and transport maneuverability. Attached Figure Description

Detailed Implementation

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] like Figure 1 As shown: A tracked towing flatbed trailer type heavy-duty anti-impact support transport vehicle, including a towing vehicle and a flatbed trailer, which are connected by a swing hinge frame 7. The flatbed trailer includes a carrying flatbed 11, which includes a front flat section, a rear flat section, and a middle sunken transport platform; a front carrying wheel axle 9 is installed at the bottom of the front flat section, and a rear carrying wheel axle 12 is installed at the bottom of the rear flat section; the front carrying wheel axle 9 and the rear carrying wheel axle 12 are not powered, and the flatbed trailer moves by passive towing. An auxiliary loading and unloading mechanism is provided on one side of the carrying plate 11, and a protective mechanism is provided on the other side. The auxiliary loading and unloading mechanism is used to drag the anti-impact bracket 14 from the side to the sunken transport platform, or to drag it in the opposite direction to unload it. The protective mechanism works with the auxiliary loading and unloading mechanism to prevent the anti-impact bracket 14 on the sunken transport platform from moving laterally.

[0020] The tractor is a tracked vehicle. The tractor includes a tractor frame 1, with a tracked running gear 5 installed on the lower part of the tractor frame 1. The upper part of the tractor frame 1 is arranged from front to back as a cab 2, a hydraulic system 3, and an explosion-proof diesel engine system 4. It is designed with a narrow body structure, and the width of the tractor is designed to be within 1.6m to ensure smooth passage through narrow driving lanes.

[0021] like Figure 2 , Figure 3 , Figure 4 As shown: The auxiliary loading and unloading mechanism includes two sets of horizontal pull cylinders and a chain 15. The two sets of horizontal pull cylinders are respectively arranged on the vertical surfaces of the sunken transport platform. Each set of horizontal pull cylinders includes an upper horizontal pull cylinder 16 and a lower horizontal pull cylinder 17 arranged in parallel. The cylinder barrels of the upper horizontal pull cylinder 16 and the lower horizontal pull cylinder 17 are movably nested in the guide holes of the bearing plate 11. The piston rods are connected to the bearing plate 11 by a pin. The cylinder barrels of the upper horizontal pull cylinder 16 and the lower horizontal pull cylinder 17 cooperate with the guide holes of the bearing plate 11 to form a sliding guide structure, which effectively resists the radial force when dragging the anti-impact bracket 14. The piston rod of the upper horizontal pull cylinder 16 faces the right side of the bearing plate 11, and the piston rod of the lower horizontal pull cylinder 17 faces the left side of the bearing plate 11. The two sides of the chain 15 can optionally be connected to the cylinder barrel ends of the two upper horizontal pull cylinders 16 or the cylinder barrel ends of the two lower horizontal pull cylinders 17.

[0022] When loading the anti-impact bracket 14, a chain 15 is used to secure it. In the first stage, the chain 15 is connected to the chain sockets at the cylinder ends of the two upper horizontal pull cylinders 16. The two upper horizontal pull cylinders 16 retract, dragging the anti-impact bracket 14 to the front of the bearing plate 11. In the second stage, the chain 15 is connected to the chain sockets at the cylinder ends of the two lower horizontal pull cylinders 17. The lower horizontal pull cylinders 17 are used to compensate for the stroke defects of the upper horizontal pull cylinders 16. The two lower horizontal pull cylinders 17 extend, dragging the anti-impact bracket 14 to the bearing plate 11, further pulling the anti-impact bracket 14 into position. Before transport, the two lower horizontal pull cylinders 17 are reset and retracted. The chain 15 is reconnected to the cylinder ends of the two lower horizontal pull cylinders 17. The lower horizontal pull cylinders 17 push the chain 15 to keep the anti-impact bracket 14 in a fixed state, improving transportation safety.

[0023] The protective mechanism includes a sliding side guard plate 19, which, together with the chain 15, reliably fixes the anti-impact bracket 14. The two transverse plates of the sliding side guard plate 19 are slidably connected to the supporting plate 11, and the longitudinal plate between the two transverse plates intercepts the front and rear flat sections of the supporting plate 11. A side guard plate telescopic cylinder 18 connects the sliding side guard plate 19 and the supporting plate 11, enabling the lateral extension and retraction of the sliding side guard plate 19. When transporting the anti-impact bracket 14, the sliding side guard plate 19 extends to accommodate different bracket sizes; when unloaded, the sliding side guard plate 19 retracts to reduce the overall width of the machine.

[0024] like Figure 5As shown: The swing articulated frame 7 includes a front cross 7.1, a rear cross 7.2, a steering cylinder 7.3, a vertical hinge pin 7.4, and a cylinder pin 7.5; the front cross 7.1 is hinged to the tractor unit via the front horizontal hinge pin 6, and the rear cross 7.2 is hinged to the flatbed trailer via the rear horizontal hinge pin 8. The rotation axes of the front horizontal hinge pin 6 and the rear horizontal hinge pin 8 are both parallel to the ground, ensuring the ground adaptability of the tractor unit and the flatbed trailer; the front cross 7.1 and the rear cross 7.2 are hinged via the vertical hinge pin 7.4; a steering cylinder 7.3 is arranged on each side of the front cross 7.1 and the rear cross 7.2, and the two ends of the steering cylinder 7.3 are hinged to the front cross 7.1 and the rear cross 7.2 via the cylinder pin 7.5 respectively.

[0025] A spherical bearing is installed at the hinge pin 7.4 to achieve universal joint between the front cross 7.1 and the rear cross 7.2, so as to accommodate the towing and walking of the tractor and the flatbed trailer, and to allow the tractor and the flatbed trailer to twist; a spherical bearing is installed at the cylinder pin 7.5 to achieve universal joint between the steering cylinder 7.3 and the front cross 7.1 and the rear cross 7.2, so as to prevent the cylinder from getting stuck when the tractor and the flatbed trailer twist.

[0026] Steering cylinder 7.3 switches between active and passive modes. When the vehicle is moving forward, the tractor pulls the flatbed trailer, and steering cylinder 7.3 is in passive mode and does not bear any force, but extends and retracts accordingly. When the vehicle is reversing, steering cylinder 7.3 actively bears the force and adjusts the direction of the flatbed trailer to meet the vehicle's reversing steering requirements.

[0027] like Figure 6 , Figure 7 As shown: Both the front load-bearing wheel axle 9 and the rear load-bearing wheel axle 12 include a tire 9.1, a sliding sleeve 9.2, and a sliding lifting axle 9.4; the sliding sleeve 9.2 is slidably inserted into the sliding lifting axle 9.4, and the sliding flat key 9.3 on the sliding sleeve 9.2 cooperates with the keyway of the sliding lifting axle 9.4 to restrict the rotation of the sliding sleeve 9.2; lifting cylinders 9.5 are installed inside the sliding sleeve 9.2 and the sliding lifting axle 9.4; the two ends of the sliding lifting axle 9.4 are connected to tire brakes 9.6 by bolts, and the tire brakes 9.6 are connected to the tire 9.1 by bolts; the tire brakes 9.6 are spring brake hydraulic release type, the brakes are released hydraulically when driving, and the spring brakes are applied when parking to ensure parking safety.

[0028] The top end of the sliding sleeve 9.2 in the front load-bearing wheel axle 9 is connected to the load-bearing plate 11 by bolts; as Figure 8As shown: The sliding sleeve 9.2 in the rear bearing wheel axle 12 has a hinge pin hole 12.1 at its top. The axis of the hinge pin hole 12.1 is perpendicular to the axis of the tire 9.1 of the rear bearing wheel axle 12. The rear wheel axle swing pin 13 is installed in the hinge pin hole 12.1 and hinged to the bearing plate 11. The rear bearing wheel axle 12 has a swing design, which allows it to twist and undulate with the roadway floor. The four tires of the flatbed trailer are always in contact with the ground, ensuring the stability and passability of the flatbed trailer in the uneven underground roadway and reducing the risk of support instability caused by bumps.

[0029] When the machine is moving, the front bearing wheel axle 9 and the rear bearing wheel axle 12 are raised so that the bearing plate 11 is off the ground. When loading and unloading the bracket, the front bearing wheel axle 9 and the rear bearing wheel axle 12 are lowered so that the bearing plate 11 is on the ground to facilitate the loading and unloading of the bracket.

[0030] like Figure 2 As shown: Support columns 10 are erected on the front and rear flat sections of the bearing plate 11. The support columns 10 are used to stabilize the flatbed trailer body. When the bracket is loaded and unloaded laterally, the support columns 10 extend to support the roof of the roadway to ensure the stability of the whole machine. The support columns 10 are staggered with the front bearing wheel axle 9 and the rear bearing wheel axle 12 respectively to prevent interference.

[0031] Flat rollers 20 are installed on the sunken transport platform carrying the flat plate 11. The flat rollers 20 are evenly installed on the plane of the sunken transport platform, with a total of 8 sets. The axis of the flat rollers 20 is parallel to the longitudinal direction of the flat plate 11, and the tangent of the rollers is slightly higher than the plane to reduce the sliding resistance when the anti-impact bracket 14 moves laterally. A flipping wedge 22 is connected to one side edge of the sunken transport platform through a flipping wedge hinge shaft 23 to provide transition support for the anti-impact bracket 14 when it is loaded onto the vehicle. The flipping wedge 22 is on the same side as the auxiliary loading and unloading mechanism. Flat rollers 20 are installed on the inclined surface of the flipping wedge 22 to reduce the resistance of the anti-impact bracket 14 when it moves laterally to load onto the vehicle.

[0032] Side impact rubber blocks 21 are installed on both sides of the front and rear flat sections of the load-bearing plate 11 to reduce collision damage.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
