Referring to fig. 3, 4 and 5, in a normal operation of the ordinary rail tractor on a slope of less than 10 degrees, a first implementation method of the rope breaking protection device 2 comprises the following steps:
in the gravity unlocking device 2-1, a push rod 2-1-1 can freely slide in holes at two ends of a fourth fixed sleeve 2-1-5, the sliding distance can be adjusted by positioning nuts 2-1-3; the pressure of the fourth spring 2-1-2 can be adjusted by the adjusting pad 2-1-4. A first lock rod 2-2-1 in the first gear component 2-2 can freely slide in a hole at the front end of the second fixed sleeve 2-2-2, a first stop block is arranged at the head of the first lock rod 2-2-1, the first stop block 2-2-6 and the first lock rod 2-2-1 are arranged in an L shape, and the first stop block 2-2-6 can be inserted into a groove at the side surface of the second fixed sleeve 2-2-2, so that the first lock rod 2-2-1 can be prevented from rotating, and the area of a lock head is increased; one end of a second spring 2-2-3 is inserted into a hole at one end of a second fixed sleeve 2-2-2, a first lower spring seat 2-2-4 is arranged in the hole, a first adjusting screw 2-2-5 is also arranged in the hole at the rear part, the first adjusting screw 2-2-5 can adjust the pressure of the second spring 2-2-3, the other end of the second spring 2-2-3 is arranged on a first upper spring seat, and a first lock rod 2-2-1 is fixed on the first upper spring seat and extends out of the hole at the front part of the second fixed sleeve 2-2-2.
Optionally, the push rod 2-1-1 comprises a gravity block arranged in the middle of the push rod, and the gravity block is columnar and is coaxial with the rod body of the push rod 2-1-1. When the tractor normally runs on a slope of less than 10 degrees, the push rod 2-1-1 of the gravity unlocking device 2-1 does not move under the action of the fourth spring 2-1-2 and friction force; due to the fact that the head of the first lock rod 2-2-1 of the first gear component 2-2 loses pressure, the first lock rod moves towards the gravity unlocking device 2-1 under the action of the second spring 2-2-3 at the rear portion of the first gear component, one end of the head of the flashboard 2-5-1 of the brake triggering component 2-5 is blocked after the first lock rod moves, and the position of the flashboard 2-5-1 enables the oil path of the hydraulic valve 2-6 to be in a blocking state.
The pressure oil in the oil cylinder of the brake 5 must be decompressed through the oil circuit of the hydraulic valves 2-6, and the brake block of the brake 5 is closed under the action of the spring force for braking only after the pressure is decompressed. Because the oil paths of the hydraulic valves 2 to 6 are locked, the pressure oil in the oil cylinder of the brake 5 is in a pressure maintaining state, and the brake block of the brake 5 is always in an opening state under the action of the oil pressure.
In the rope breaking unlocking device 2-3, the traction rod 2-3-5 can freely slide in holes at two ends of the fifth fixed sleeve 2-3-4, and the sliding distance can be determined by the upper end part of the traction rod 2-3-5 and a middle positioning step; the positioning sleeve 2-3-2 is sleeved on the traction rod 2-3-5, the bottom of the hole is tightly propped against the step in the middle of the traction rod 2-3-5 and is locked by the nut 2-3-1, the fifth spring 2-3-3 is sleeved on the excircle of the positioning sleeve 2-3-2 and is compressed by the movement of the traction rod 2-3-5, the spring parameter is fixed, and the required pressure is determined by the length of the positioning sleeve 2-3-2.
A second lock rod 2-4-1 in the second gear component 2-4 can freely slide in a hole at the front end of a third fixed sleeve 2-4-2, a second stop block 2-4-6 is arranged at the head of the second lock rod 2-4-1, the second baffle block 2-4-6 and the first lock rod 2-2-1 are arranged in an L shape, and the L part is inserted into a groove on the side surface of the third fixed sleeve 2-4-2, so that the second lock rod 2-4-1 can be prevented from rotating, and the area of the lock head is increased; one end of a third spring 2-4-3 is inserted into a hole at the rear part of the second lock rod 2-4-1, the other end of the third spring is plugged into a hole at the rear end of the first fixed sleeve 2-4-2 together with a second lower spring seat 2-4-4, a second adjusting screw 2-4-5 at the tail part can adjust the pressure of the fourth spring 2-4-3, the other end of the third spring 2-4-3 is arranged in a second upper spring seat, and the second lock rod 2-4-1 is arranged on the second upper spring seat.
When the tractor runs on a slope less than 10 degrees, the traction rod 2-3-5 moves forwards in the hole of the fifth fixed sleeve 2-3-4 under the action of load tension, and the forward movement distance is controlled by the positioning sleeve 2-3-2; when the traction rod 2-3-5 moves forwards, the fifth spring 2-3-3 is compressed at the same time, and the compression amount of the fifth spring 2-3-3 is also controlled by the positioning sleeve 2-3-2; the nut 2-3-1 fixes the positioning sleeve 2-3-2 on the traction rod 2-3-5. When the traction rod 2-3-5 is in a forward moving state under the action of load tension, the head of a second lock rod 2-4-1 of the second gear component 2-4 and the tail of the traction rod 2-3-5 are in a separated state, so that a second stop block moves out in the direction of the traction rod 2-3-5 under the action of a rear third spring 2-4-3, and after the head of the second lock rod 2-4-1 moves out, the second stop block and a first stop block on a first lock rod 2-2-1 of the first gear component 2-2 simultaneously stop the end face of a flashboard 2-5-1 of a brake triggering component 2-5; even if the first gear component 2-2 malfunctions, the position of the brake plate 2-5-1 of the brake triggering component 2-5 cannot be changed, and the hydraulic valve 2-6 is still in an oil circuit locking state.
When the common rail tractor normally runs on a slope with the angle less than 10 degrees, the first lock rod 2-2-1 of the first gear component of the rope breakage protection device 2 and the second stop block at the head of the second lock rod 2-4-1 of the second gear component both extend out of the base body, and the two lock rods block the flashboard 2-5-1 at the same time, so that the hydraulic valve 2-6 cannot be reversed and is always in an oil circuit locking state.
Referring to fig. 6, 7 and 8, a second method for implementing the rope breakage protection device 2 when the common rail tractor breaks a rope on a slope of less than 10 degrees is as follows:
when the tractor breaks a rope on a slope of less than 10 degrees, the first gear component 2-2 of the rope breaking protection device 2 is in the same working state as the first gear component in normal operation on the slope of less than 10 degrees, and at the moment, the hydraulic valve 2-6 is still in a locking state due to the position of the brake plate 2-5-1.
After the common rail transport tractor breaks a rope on a slope with the angle less than 10 degrees, the load moves towards the slope under the action of inertia, the rope breaking unlocking device 2-3 of the rope breaking protection device 2 loses the tension of the traction steel wire rope 4, the traction rod 2-3-5 slides backwards along the guide holes at the two ends of the fifth fixed seat 2-3-4 under the action of the fifth spring 2-3-3, and the traction rod 2-3-5 pushes the second lock rod 2-4-1 of the second gear component to move backwards while sliding backwards, so that the second lock rod 2-4-1 is unlocked; although the second lock rod 2-4-1 is unlocked, the first lock rod 2-2-1 is still in a locking state, and the end part of the gate plate 2-5-1 of the brake trigger assembly 2-5 is still blocked, so that the oil path of the hydraulic valve cannot be communicated.
When the common rail tractor breaks a rope on a slope of less than 10 degrees, the first lock rod 2-2-1 of the first gear component of the rope breaking protection device 2 is continuously in a locking state, and the second lock rod 2-4-1 of the second gear component is unlocked under the pushing of the draw bar 2-3-5 of the rope breaking unlocking device 2-3, but one of the two lock rods blocks the flashboard 2-5-1, so that the hydraulic valve cannot be reversed and still stays in an oil circuit locking state.
Referring to fig. 9, 10 and 11, when the ordinary rail tractor normally runs on a slope of more than or equal to 10 degrees, the third implementation method of the rope breakage protection device 2 comprises the following steps:
when the tractor normally runs on a slope of more than or equal to 10 degrees, the mass of the whole push rod is increased due to the fact that the volume of the middle of the push rod 2-1-1 of the gravity unlocking device 2-1 is increased (the gravity block part); when the whole device is in a state that the inclination angle is larger than or equal to 10 degrees, the push rod 2-1-1 slides forwards under the action of gravity and overcomes the direction of the fourth spring 2-1-2, when the push rod 2-1-1 moves, the head of the push rod props against the head of the first lock rod 2-2-1, the first lock rod 2-2-1 retreats until the position of the first stop block 2-2-6 retracts into the slotted hole at one end of the first fixed sleeve 2-2-2, and the first gear component 2-2 is unlocked.
When the tractor normally runs on a slope of more than or equal to 10 degrees, the working states of the rope breaking unlocking device 3-1 and the second stop assembly 2-4 are the same as the working states of the tractor when the tractor normally runs on the slope of less than 10 degrees, and therefore the second stop assembly 2-4 is in a locking state at the moment.
The first gear assembly 2-2 is unlocked, the second gear assembly 2-4 is locked, the head of the brake plate 2-5-1 of the brake triggering assembly 2-5 is still blocked, and the hydraulic valve 2-6 is still in an oil circuit locking state.
Referring to fig. 12, 13 and 14, when the common rail tractor breaks the rope on a slope of more than or equal to 10 degrees, the fourth implementation method of the rope breaking protection device 2 comprises the following steps:
when the tractor breaks the rope on the slope of more than or equal to 10 degrees, the working state of the gravity unlocking device 2-1 and the first gear component 2-2 is the same as the working state of the tractor in normal operation on the slope of more than or equal to 10 degrees, so that the first gear component 2-2 is in an unlocking state.
When the tractor breaks the rope on the slope of more than or equal to 10 degrees, the working state of the rope breaking unlocking device 2-3 and the second gear component 2-4 is the same as that of the tractor when the rope breaks on the slope of less than 10 degrees, so that the second gear component 2-4 is in an unlocking state at the moment.
Because the first gear component 2-2 and the second gear component 2-4 are unlocked, after the two stop dogs are unlocked completely, the gate plate 2-5-1 of the brake triggering component 2-5 is provided with a channel, the gate plate 2-5-1 moves forwards under the action of the first spring 2-5-2, and the moving distance is controlled by the limiting block 2-5-3; after the flashboard 2-5-1 moves, the rod part drives the normally closed hydraulic valve 2-6 to change direction to connect an oil way until an oil cylinder of a system brake 5 is decompressed; because the used brake 5 is of a failure safety type, the brake 5 starts to brake after the oil cylinder is decompressed.
The embodiment of the invention also provides endless rope common rail transportation equipment, and by adopting the rope breaking protection device, when the transportation equipment breaks a rope on a slope with the angle of more than 10 degrees, automatic braking can be controlled through the rope breaking protection device, so that the safety performance of the equipment is improved.
