Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic monorail hanging and rail restoration, in particular to a convenient pneumatic rail restoration device. Background Art

[0002] The pneumatic monorail crane is composed of a track suspended above the tunnel, and is combined with a pneumatic hoist, a main traction device, a failure brake device, a carrier vehicle, a control system and other parts. Each section of the track is composed of an I-beam, a chain, and a shackle. The system is pulled by the main traction device and runs along the track.

[0003] In the process of rail transportation in mines, due to factors such as the ups and downs of the tunnels, turns and the quality of double-track laying, it is easy for the mine car to fall off the track. Once the mine car falls off the track, it is necessary to promptly re-track the derailed mine car. The general treatment method requires that the materials be unloaded from the car, and then the mine car is lifted by manpower, crowbars, hand winches, etc., and then the mine car is manually pushed to re-track. This treatment method not only requires the cooperation of multiple people, but also has high labor intensity and is very likely to cause injuries to operators. The current commonly used treatment method is to use an air bag jack to lift and re-track the mine car. Although it can reduce the labor intensity during re-tracking, it still needs to manually push the mine car to re-track, which is not very convenient. In addition, during the re-tracking process, it is impossible to avoid the problem of the mine car falling again due to the accidental loss of pressure of the air bag jack, which is very likely to cause damage to the mine car or the re-tracking device.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The existing technology is not very convenient during the rerailing process, and cannot avoid the problem that the mine car falls again due to accidental decompression of the airbag jack. The following solutions can be used to solve the problem:

[0028] See also Figure 1 - Figure 5As shown, a portable pneumatic rerailing device comprises a bottom plate 1, a slide seat 2 is installed on the top of the bottom plate 1, and an air bag jack 21 is fixedly installed on the top of the slide seat 2. The air bag jack 21 is moved by the slide seat 2 on the bottom plate 1, and then the lifted mine car is rerailed. The top of the air bag jack 21 is fixedly connected with a top plate 22, and an anti-falling component 3 is symmetrically arranged between the top plate 22 and the slide seat 2 and on both sides of the air bag jack 21. The anti-falling component 3 is used to realize synchronous self-locking when the top plate 22 rises, so as to avoid the mine car falling again due to accidental decompression of the air bag jack 21 during the rerailing process. The anti-falling component 3 includes a sleeve 31, a tooth plate 32 and a tongue 33. The top of the slide 2 is fixedly connected with the sleeve 31, and the bottom of the top plate 22 is fixedly connected with the tooth plate 32 which is slidably connected with the corresponding sleeve 31. A tongue 33 which is adapted to the tooth plate 32 is installed on the top of one side of the sleeve 31. When the top plate 22 rises, the tooth plate 32 is synchronously driven to move in the sleeve 31, and cooperates with the tongue 33 on the top of one side of the sleeve 31 to self-lock the top plate 22 during the rising process. The sliding connection between the sleeve 31 and the tooth plate 32 improves the effect of pushing the top plate 22 to move sideways during the lateral movement of the slide 2.

[0029] Trapezoidal slide rails 11 are symmetrically fixedly connected to both sides of the top of the base plate 1, and a trapezoidal slide groove 23 is provided at the bottom of the slide seat 2 for sliding connection with the corresponding trapezoidal slide rails 11. The cooperation between the trapezoidal slide rails 11 and the trapezoidal slide groove 23 can avoid the slide seat 2 and the base plate 1 from being separated, and ear plates are symmetrically fixedly connected to the outer walls on both sides of the slide seat 2. An adjusting cylinder 24 is fixedly connected between the top of the base plate 1 and one side of the corresponding ear plate. The adjusting cylinder 24 is used to drive the slide seat 2 to slide on the top of the base plate 1, so that after the air bag jack 21 lifts the derailed mine car, it is possible to avoid the need for manual pushing and re-tracking of the mine car.

[0030] The outer wall of the tube sleeve 31 is fixedly connected with a fixing seat 34 at the position corresponding to the latch tongue 33, and the fixing seat 34 is provided with an active groove that runs through the interior of the tube sleeve 31, and the latch tongue 33 is slidably connected in the corresponding active groove, and the side of the latch tongue 33 away from the tooth plate 32 is fixedly connected with a pull rod 35 that runs through the outer side of the fixing seat 34, and the pull rod 35 is slidably connected with the fixing seat 34, and the outer sleeve of the pull rod 35 is provided with a return spring 36, and the two ends of the return spring 36 are respectively fixedly connected to the latch tongue 33 and the inner wall of the active groove, and the set latch tongue 33 is compressed by the return spring 36, so that the tooth plate 32 is in the process of ascending, and the latch tongue 33 is continuously separated and engaged with the tooth groove on the tooth plate 32, thereby realizing self-locking of the top plate 22 at all times during the ascending process, effectively avoiding the problem that the mine car falls again due to accidental decompression of the air bag jack 21, and the set pull rod 35 can pull the latch tongue 33 to separate from the tooth plate 32, thereby realizing the resetting of the air bag jack 21.

[0031] A plurality of rubber anti-sliding blocks 25 are fixedly connected to the top plate 22 to increase the contact friction between the top plate 22 and the derailed mine car, thereby improving the lateral shifting effect of the airbag jack 21 in driving the mine car to be lifted.

[0032] A base plate 12 is provided on the top of the bottom plate 1 on the outside of the airbag jack 21, and the bottom of the base plate 12 is fixedly connected with vertical rods 13 at the four corners, and the bottom of the vertical rods 13 are rotatably connected with rollers 14. A through groove for the corresponding vertical rods 13 to pass through is opened on the bottom plate 1, and a tension spring 15 is fixedly connected to the outside of each vertical rod 13 between the bottom plate 1 and the base plate 12. The vertical rods 13 and rollers 14 provided on the base plate 12, and the base plate 1 is separated from the ground by the tension springs 15, so as to facilitate movement. In the process of re-tracking, when the airbag jack 21 drives the top plate 22 to rise and contact the bottom of the derailed mine car, the bottom plate 1 is simultaneously driven to descend and contact the ground. Compared with the method of contacting the ground through the rollers 14, the support stability of the airbag jack 21 can be greatly improved, thereby improving the safety of use.

[0033] One side of the base plate 12 is symmetrically fixedly connected with an armrest 16 , and the free end of the armrest 16 is fixedly sleeved with a rubber sleeve, so as to facilitate the movement of the device in the lane and increase the comfort between the hand and the armrest 16 .

[0034] The working process and principle of the utility model are as follows:

[0035] During use, the utility model pulls the handrail 16 and cooperates with the roller 14 on the base plate 12 to move the device to the bottom of the derailed mine car, first remotely controls the airbag jack 21 to drive the top plate 22 to rise, and the top plate 22 drives the derailed mine car to lift and make the bottom surface of the wheel slightly higher than the plane on the track, and then remotely controls the regulating cylinder 24 to drive the slide 2 to move, push the derailed mine car to move horizontally above the track, and complete the rerailing operation;

[0036] When the top plate 22 rises during the rerailing process, the tooth plate 32 is synchronously driven to move in the corresponding pipe sleeve 31. The provided latching tongue 33 is continuously separated and engaged with the tooth groove on the tooth plate 32 under the compression of the return spring 36, and the rising top plate 22 is self-locked at all times, effectively avoiding the problem that the mine car falls again due to accidental decompression of the airbag jack 21, which may easily cause damage to the mine car or the rerailing device. After the top plate 22 rises and contacts the bottom of the derailed mine car, it pushes the bottom plate 1 down and contacts the ground. Compared with the contact with the ground through the roller 14, the support stability of the airbag jack 21 is improved;

[0037] After the re-tracking is completed, the pull rod 35 is pulled to drive the latch tongue 33 to compress the reset spring 36 and separate from the tooth plate 32, thereby realizing the reset of the airbag jack 21 and the bottom plate 1.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
