Description

Technical Field

[0001] The present application relates to a steep tunnel transportation device in the field of inclined shaft construction of a water conservancy and hydropower station, and in particular to an inclined shaft rail climbing vehicle suitable for inclined shaft construction of a pumped storage power station. Background Art

[0002] In many fields such as mining and pumped storage, there are materials and personnel transportation operations in inclined shafts. These inclined shaft transportations have the characteristics of long transportation distances and steep slopes, which bring huge challenges to the transportation of materials and personnel. At present, most of the common rail transportation on steep slopes is towed by winches. There are two more serious problems in transportation on large slopes. One is that the transport vehicle may roll over, and the other is that the conventional braking system is difficult to brake on large slopes. When the transport vehicle rolls over on the track or the wire rope suddenly breaks, it will endanger the personal safety of the construction workers and hinder daily operations. Summary of the invention

[0003] The technical problem to be solved by the embodiments of the present application is to provide a safe transportation system device suitable for steep tunnel tracks, which can prevent the transport vehicle from rolling over during transportation, and when the traction wire cable suddenly breaks, the transport vehicle can be safely braked by disengaging from the winch. The system can reduce safety hazards, ensure construction safety, and has the advantages of double insurance, safety, and convenience.

[0004] The technical solution adopted by the present invention is:

[0006] The anti-rollover track system includes tracks, sleepers, fasteners and a wheel system; the sleepers are laid on the slope in a steep tunnel, the tracks are laid on the sleepers, the tracks and the sleepers are fixed by the fasteners, and the wheel systems are installed on the four corners of the transport platform, and the wheel systems are rollingly installed on the tracks and roll along the tracks.

[0007] Concave horizontal strip grooves are provided on both sides of the track. The wheel system includes a base plate and special wheels. The top surface of the base plate is fixed to the bottom surface of the transport platform. A wall panel is fixed on both sides of the bottom surface of the base plate. An axis is fixed on each wall panel. A special wheel is rotatably mounted on the axis through a bearing. The two special wheels on both sides are respectively embedded in the concave horizontal strip grooves on both sides of the track and roll.

[0008] The transport platform comprises a vehicle body, hanging wheels and heightening blocks. The top surface of the vehicle body is provided with hanging wheels for connecting steel wire ropes, and heightening blocks are fixed at the four corners of the bottom surface of the vehicle body. The bottom surface of the heightening blocks is used to install the wheel system of the anti-rollover track system.

[0009] The electromagnetic brake is arranged on the vehicle body floor of the transport platform and is located above the track of the anti-rollover track system.

[0010] The electromagnetic brake comprises a brake housing, an electromagnet, a cross bar and a synchronization mechanism; a track groove is arranged in the middle upper part of the brake housing, a hollow structure is arranged in the middle lower part, and installation chambers are arranged on both sides; the electromagnet and the cross bar are arranged at the hollow structure, the cross bar is arranged parallel to the track groove, and the two ends of the cross bar are respectively fixedly connected with the first upper and lower sliders and the second upper and lower sliders after the cross bar moves through the electromagnet, the first upper and lower sliders and the second upper and lower sliders are respectively movable up and down in the upper and lower guide grooves arranged in their respective installation chambers, and the electromagnets are respectively sleeved with the first buffer spring and the second buffer spring on the cross bar between the first upper and lower sliders and the second upper and lower sliders; a first left and right slider is arranged in the track groove, the first left and right sliders are freely movable along the track groove in the track groove, and the two ends of the first left and right sliders are respectively connected to the electromagnet via a crank slider assembly; a first electric hydraulic actuator and a second electric hydraulic actuator are respectively installed in the installation chambers on both sides, the actuating rod of the first electric hydraulic actuator is downward and fixedly connected to the first upper and lower sliders, and the actuating rod of the second electric hydraulic actuator is downward and fixedly connected to the second upper and lower sliders; the second upper and lower sliders are connected to the first left and right sliders via the synchronization mechanism.

[0011] The crank slider assembly comprises a connecting crank and a crank slider, the upper end of the connecting crank is hinged to the first left and right sliders, the lower end of the connecting crank is connected to the crank slider, and the crank slider is hinged to the side of the electromagnet.

[0012] The synchronization mechanism includes a second pinion, a first pinion, a large gear, a first rack and a second rack arranged on the side of the second upper and lower sliders. The second pinion, the first pinion and the large gear are arranged in the installation chamber from bottom to top and are meshed and connected in sequence. The second rack is meshed with the second pinion at the bottom. A first rack is provided above the large gear, and the first rack is meshed with the large gear; the first rack is fixedly connected to the second left and right sliders via a connecting rod, the second left and right sliders are fixedly connected to one end of the inner rod of the telescopic rod, and the other end of the inner rod of the telescopic rod is fixedly connected to the first left and right sliders via the telescopic rod outer shell.

[0013] In the present invention, manual work or material transportation is carried out in a steep tunnel. A common method is to lay tracks and use a winch to raise and lower the platform. At this time, two problems may arise:

[0014] First, the platform may roll over due to unstable operation. The existing anti-rollover method is to add fasteners under the platform to buckle on the track. Such fasteners are not firm and are easy to break. Based on the principle of reducing the activity space, the anti-rollover track system in this application, wherein the wheels are confined in the track, achieves the ideal result.

[0015] The second is the serious harm caused by the breakage of the winch cable. The current large-slope track transportation has no braking device and relies only on the winch to drag. Based on the principle of safety first, a braking system is added to the existing platform. The existing brakes include friction braking, electromagnetic braking, etc. Friction braking is slow, so electromagnetic braking is selected. In a track with a large slope, if only the wheel is stopped, the sliding friction between the wheel and the track is very likely to fail to brake the platform. Therefore, the characteristics of the super-large magnetic force of the electromagnet after power is turned on are considered, and the electromagnet is used to absorb it to the track for rapid braking.

[0016] The beneficial effects of the present invention are:

[0017] The anti-rollover track system applied by the present invention can effectively avoid the rollover risk caused by uneven weight distribution of the transport platform. At the same time, the conventional braking method is replaced by the method of using electromagnets and rail adsorption, so that the transport platform can brake on the rail with a large slope when the wire rope suddenly breaks, which has the advantages of double insurance, safety and convenience.

[0018] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

After the cross bar 3-17 moves through the electromagnet 3-15, the two ends are fixedly connected to the first upper and lower slider 3-2 and the second upper and lower slider 3-13-15 respectively. The first upper and lower slider 3-2 and the second upper and lower slider 3-13-15 can be lifted and lowered in the upper and lower guide grooves arranged in their respective installation chambers.

The crank slider assembly on the other side includes a second connecting crank 3-8 and a crank slider, which are arranged in the same structure.

[0050] The first electro-hydraulic actuator 3-10 and the second electro-hydraulic actuator 3-18 are respectively installed in the installation chambers on both sides. The actuating rod of the first electro-hydraulic actuator 3-10 faces downward and is fixedly connected to the first upper and lower sliders 3-2. The actuating rod of the second electro-hydraulic actuator 3-18 faces downward and is fixedly connected to the second upper and lower sliders 3-13-15. The second upper and lower sliders 3-13-15 are connected to the first left and right sliders 3-11 via a synchronization mechanism 3-13.

[0051] like Figure 8As shown, the synchronization mechanism 3-13 includes a second pinion 3-13-13, a first pinion 3-13-8, a large gear 3-13-5, a first rack 3-13-4 and a second rack 3-13-14 arranged on the side of the second upper and lower sliders 3-13-15. The second pinion 3-13-13, the first pinion 3-13-8 and the large gear 3-13-5 are arranged in sequence from bottom to top in the installation chamber and are meshed and connected in sequence. The second rack 3-13-14 and the second pinion at the bottom are connected to each other. The wheel 3-13-13 is meshed, and a first rack 3-13-4 is provided above the large gear 3-13-5, and the first rack 3-13-4 is meshed with the large gear 3-13-5; the first rack 3-13-4 is fixedly connected to the second left and right sliders 3-13-2 via the connecting rod 3-13-3, the second left and right sliders 3-13-2 are fixedly connected to one end of the telescopic rod inner rod 3-13-1, and the other end of the telescopic rod inner rod 3-13-1 is fixedly connected to the first left and right sliders 3-11 via the telescopic rod outer shell 3-12.

[0052] The first left and right sliders 3-11 and the second left and right sliders 3-13-2 are both embedded in the track groove and move freely along the track groove.

[0053] In a specific implementation, the second pinion 3-13-13, the first pinion 3-13-8, and the large gear 3-13-5 are all mounted on the gear shaft through bearings, and the gear shaft is fixed to the inner wall of the mounting chamber.

[0054] The second pinion 3-13-13 is mounted on the second pinion shaft 3-13-11 through the bearing 3-13-12, and the second pinion shaft 3-13-11 is fixed to the inner wall of the mounting chamber; the first pinion 3-13-8 is mounted on the first pinion shaft 3-13-9 through the bearing 3-13-10, and the first pinion shaft 3-13-9 is fixed to the inner wall of the mounting chamber; the large gear 3-13-5 is mounted on the large gear shaft 3-13-6 through the bearing 3-13-7, and the large gear shaft 3-13-6 is fixed to the inner wall of the mounting chamber.

[0055] The present invention sets a synchronization mechanism 3-13 to drive the second upper and lower sliders 3-13-15 and the first left and right sliders 3-11 to move in conjunction, so that the electromagnet 3-15 and the crank 3-6 / 3-8 are relatively stationary and descend, thereby preventing the crank 3-6 / 3-8 from pushing upward and causing locking when the electromagnet 3-15 descends.

[0056] In an embodiment, Figure 3 As shown, the track 2-1 has an additional groove on the basis of its I-shaped cross section, and a protruding shaft 2-4-10 is provided on the inner side of the second special wheel 2-4-5 / 2-4-8, and the protruding shaft 2-4-10 is located in the groove.

[0057] like Figure 4As shown, a single wheel system 2-4 includes two second special wheels 2-4-5 / 2-4-8, and the two second special wheels 2-4-5 / 2-4-8 are located on both sides of the track 2-1. The second special wheels 2-4-5 / 2-4-8 clamp the track 2-1 and the protruding shaft 2-4-10 is located in the groove, which can limit the second special wheels 2-4-5 / 2-4-8 and prevent the transport platform from tipping over due to eccentric force, thereby ensuring the safety and reliability of the transport platform.

[0058] The electromagnet 3-15 in the electromagnetic brake 3 generates magnetic force by power supply to attract the track 2-1 so that the transport platform 4 stops sliding down. The electromagnet 3-15 and the track 2-1 are adsorbed to replace the conventional braking method, so that the transport platform 4 can brake on a steep rail when the wire rope suddenly breaks.

[0059] When the electromagnet 3-15 is adsorbed on the track 2-1, the two buffer springs 3-14 and 3-16 are deformed, so that the transport platform 4 is decelerated to a stationary state with a relatively small acceleration. The buffer spring is used to reduce the acceleration during deceleration, ensuring the safety of personnel and materials during emergency braking. It has the advantages of double insurance, safety and convenience.

[0060] When the electromagnet 3-15 is not working, it is at a certain distance from the track 2-1. The electromagnet 3-15 moves left and right on the crossbar 3-17, and can move up and down driven by the electric hydraulic actuators 3-10 and 3-18. The electromagnet can move up and down and left and right at the same time, and can also move left and right alone.

[0061] The working principle of the embodiment of the present invention is as follows:

[0062] Under normal circumstances, the up and down movement of the transport platform 4 along the anti-rollover track system 2 is achieved by the winch 1 pulling and releasing the steel wire rope.

[0063] When the wire rope suddenly breaks, the electromagnetic brake 3 starts to work. The upper and lower sliders 3-2 and the upper and lower sliders 3-13-15 move downward under the extension of the electro-hydraulic actuators 3-10 and 3-18, so that the rod 3-17 for moving the electromagnet and the electromagnet 3-15, the buffer spring 3-14 and the buffer spring 3-16 thereon move downward. At the same time, through the transmission of the synchronization mechanism 3-13, the left and right sliders 3-11 and the left and right sliders 3-13-2 move synchronously to the middle, and the connecting crank 3-6 / 3-8 rotates.

[0064] When the electromagnet 3-15 fits with the track 2-1, the electric hydraulic actuator 3-10 / 3-18 stops extending, the left and right sliders 3-13-2 stop moving, the connecting crank 3-6 / 3-8 rotates to the specified position, and the rotating block 3-5 of the connecting crank pops out and snaps into the groove of the connecting crank 3-6 / 3-8, making the left and right sliders 3-11, the connecting crank 3-6 / 3-8 and the electromagnet 3-15 relatively still.

[0065] When the electromagnet 3-15 is powered on and adsorbed to the track 2-1, the electromagnet 3-15 is stationary relative to the track 2-1. Since the left and right sliders 3-11, the connecting cranks 3-6 / 3-8 and the electromagnet 3-15 are relatively stationary, and the left and right sliders 3-13-2 no longer move, the electromagnet 3-15 slides left and right on the rod 3-17 used for moving the electromagnet, and the telescopic rod housing 3-12 and the telescopic rod inner rod 3-13-1 move relative to each other. The buffer springs 3-14 and 3-16 are deformed to decelerate the brake housing 3-1 to a stationary state, and the brake housing 3-1 is fixedly connected to the transport platform, thereby decelerating the transport platform to a stationary state.

[0066] The safe transportation system device for steep-slope tunnel tracks according to the embodiment of the present invention has a simple structure and can be used in a variety of steep-slope transportation situations, thereby improving engineering safety and reliability.
