Description

Technical Field

[0001] The invention relates to the technical field of hoisting, and in particular to a mine electric locomotive rail transportation hoisting device. Background Art

[0002] With the development of the coal industry, most of the transportation of underground equipment, materials, etc. is carried out by using mine overhead line locomotives to pull mine cars on rails. The effect of only clamping and fixing the hook during transportation is not good for the clamping and limiting effect of the cable above the hook. When the crane is lifting, the object being lifted will shake due to the deviation between the lifting point position of the object being lifted and the hook or the inertia generated by the crane during the start and stop process. At the same time, it is necessary to wait until the object being lifted stops shaking before it can be put down, which further affects the efficiency of working time. The existing use of multiple pulleys to limit the position of the steel rope to limit the shaking of the object being lifted, and then due to its anti-swaying characteristics, when the connected hook and the lifting point position are staggered, it is necessary to move the object as a whole or over-lower the hook to let the steel rope be in a relaxed state before hooking the hook on the lifting point. If the weight of the object being lifted exceeds tens of kilograms, it is difficult to push it. Similarly, the steel rope is easy to detach from the pulley when it is in a relaxed state.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0021] In order to better understand the mine electric locomotive rail transport hoisting device provided in this embodiment, the object being hoisted may shake due to the deviation between the lifting point position of the object being hoisted and the hook or the inertia generated by the crane during the start and stop process. The specification aims to solve the above technical problems. The embodiment of the present application provides a mine electric locomotive rail transport hoisting device.

[0022] Example 1: Reference Figure 1 , which is the first embodiment of the present invention, provides a mine electric locomotive rail transportation hoisting device, comprising: The running wheel 1 is mounted on the electric locomotive 6 and the lifting beam 3. The running wheel 1 is connected to the motor on the electric locomotive 6. The power of the motor is controlled by the electric locomotive 6. The motor and the running wheel 1 are driven by the electric locomotive 6 to work, so that the running wheel 1 rotates and can move forward or backward along the track 2; Track 2, track 2 is installed on the top of the mine, the electric locomotive 6 and the lifting beam 3 move along the track 2 through the running wheel 1, the track 2 adopts a single track structure to adapt to the narrow passage in the mine, the electric locomotive 6 of the device can be a wire type electric locomotive or a battery type electric locomotive, which can be set according to the needs; Reference Figure 2-Figure 4 , a lifting suspension beam 3, a main drum 31 installed on the lifting suspension beam 3 is provided with a suspension steel rope 32, a pulley 33 is provided at the bottom of the lifting suspension beam 3, the suspension steel rope 32 passes through the pulley 33 and the suspension wheel 34 and is wound on the main drum 31, and a hook extension component 4 is movably connected to the suspension wheel 34; Specifically, the length and width of the lifting beam 3 are set according to the size of the mine. The lifting beam 3 is provided with a reducer and a driving motor connected to the main drum 31. The motor is controlled by the electric locomotive 6. After the motor transmits power to the reducer, it drives the main drum 31 to rotate forward and reverse to wind up or lower the suspension steel rope 32, and the hook extension assembly 4 is pulled up or down by the suspension steel rope 32.

[0023] Reference Figure 4-Figure 5 A block 431 is installed in the hook frame 43, and a through hole is opened inside the block 431 for the hook steel rope 42 and the hook member 45 to be inserted.

[0024] The hook member 45 includes a hook sleeve 451 whose top is fixed to the hook steel rope 42 , and the hook sleeve 451 and the rod body of the hook 452 are threadedly connected, so that the hook sleeve 451 and the hook 452 are conveniently replaced by the thread.

[0025] Wheel covers 432 are symmetrically fixed on the outer walls of both sides of the hook frame 43 , and the suspension wheel 34 is placed in the wheel cover 432 . An arc groove is provided on the top of the wheel cover 432 , and the suspension steel rope 32 passes through the arc groove and is wound around the suspension wheel 34 .

[0026] The suspension rope 32 passes through the suspension wheel 34 and the pulley 33 on one side and is fixed on the main drum 31 in sequence. The suspension wheels 34 and the pulley 33 on both sides limit the suspension rope 32 to prevent the suspension rope 32 from shaking during the suspension process.

[0027] Although the suspension steel rope 32 solves the problem of shaking due to the structural setting of the suspension wheel 34 and the pulley 33, its anti-sway setting causes the directly connected hook 452 to move up and down in the vertical direction. If the hanging point of the suspended object is misaligned with the hook 452, it is necessary to move the suspended object to align the hanging point with the hook 452, or continue to lengthen the suspension steel rope 32 so that the hook extension assembly 4 is located below the level of the hanging point as a whole. Then, the suspension steel rope 32 is in a loose state and the hook extension assembly 4 is moved to drive the hook 452 to hook on the hanging point.

[0028] The hook extension assembly 4 provided to solve the above problem can solve the shaking of the suspended object and also can eliminate the need to lengthen the suspension rope 32 or move the suspended object when the suspension point of the suspended object and the hook 452 are staggered.

[0029] The hook extension assembly 4 includes an auxiliary drum 41, a hook steel rope 42, a hook frame 43 and a hook member 45. Both ends of the auxiliary drum 41 are connected to the suspension wheel 34. The hook frame 43 is penetrated by the auxiliary drum 41 and rotates around the auxiliary drum 41. One end of the hook steel rope 42 is wound around the auxiliary drum 41 and fixed, and the other end of the hook steel rope 42 is connected to the hook member 45. A limiting portion 5 is provided on the hook frame 43 to prevent the hook member 45 from shaking.

[0030] The auxiliary drum 41 and the suspension wheel 34 rotate synchronously, and the hook frame 43 can rotate around the auxiliary drum 41. Therefore, in the process of lengthening or shortening the suspension rope 32, the suspension wheel 34 and the auxiliary drum 41 can be driven to rotate forward or reverse synchronously. When the suspension rope 32 is lengthened, the main drum 31 rotates forward and the auxiliary drum 41 also rotates forward. At this time, the rotation of the main drum 31 also synchronously lengthens the hook rope 42, so that the hook 452 can be detached from the hook member 45.

[0031] Through the above structure, when the main drum 31 rotates forward and the suspension rope 32 is lengthened, the hook rope 42 is also lengthened synchronously, and the hook rope 42 and the hook 452 can move in any direction. Through the above structure, when the suspended object and the hook 452 are staggered, the hook 452 can be pulled to hook at the suspension point, and there is no need to lengthen the hook extension component 4 or move the suspended object. At the same time, the suspension rope 32 is always in a taut state and will not detach from the pulley 33.

[0032] As the suspension rope 32 shortens to drive the hook extension assembly 4 to rise, the hook rope 42 also synchronously rotates around the auxiliary reel 41 to shorten its length, and the hook 452 also rises synchronously until the hook 452 and the hook sleeve 451 are inserted into the through hole of the hook member 45. The hook 452 and the hook sleeve 451 are restricted by the hook member 45. When the crane moves and starts and stops, the hook member 45 reduces the swing amplitude of the hook 452, thereby avoiding the existing hanging object when the crane is stopped. In order to reduce the swing, it is necessary to extend the braking time to reduce the influence of inertia on the hung object. At the same time, it is necessary to wait until the swing amplitude is reduced before the hung object can be put down.

[0033] Example 2: Reference Figure 6-Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment. Since the lifting point of the hanging object and the hook 452 are staggered, the hanging object will swing when the hook 452 lifts the hanging object. When the hanging object swings, it is difficult to insert the hanging object into the through hole of the hook member 45. It is necessary to wait until the swing amplitude of the hanging object is small before the hook 452 and the hook sleeve 451 can be inserted into the through hole of the hook member 45. In order to solve the above problem, the limiting part 5 is provided to limit the hook 452 and the hook sleeve 451 to reduce the waiting time.

[0034] The limiting part 5 includes a limiting ring 51, a limiting plate 52, a counterweight rod 53 and a connecting rod 54. The limiting ring 51 is assembled in the hook frame 43, and the connecting rod 54 rotates around the limiting ring 51. The two ends of the connecting rod 54 are respectively hinged to the counterweight rod 53 and the limiting plate 52.

[0035] The connecting rod 54 is composed of a straight arm portion 541 and a curved portion 542 . The cylinder connected to the curved portion 542 is sleeved on the limiting ring 51 for rotation. The counterweight rod 53 is arranged horizontally and the weight of the counterweight rod 53 exceeds the weight of the straight arm portion 541 and the limiting plate 52 .

[0036] The limiting ring 51 provides support for the connecting rod 54, allowing the connecting rod 54 to rotate around the limiting ring 51. Since the gravity of the counterweight rod 53 exceeds the straight arm portion 541 and the limiting plate 52, the hook sleeve 451 contacts multiple counterweight rods 53 during the process of moving upward and swinging. Since the hook sleeve 451 will swing, when the hook sleeve 451 swings to one side, the hook sleeve 451 will abut against the counterweight rod 53, and the counterweight rod 53 will drive the connecting rod 54 and the limiting plate 52 to rotate in the opposite direction, and the limiting plate 52 In the opposite direction to the swinging direction of the hook sleeve 451, the limit plate 52 limits the swinging amplitude of the hook sleeve 451. The larger the swinging direction of the hook sleeve 451, the greater the amplitude limited by the limit plate 52 in that direction, thereby continuously limiting the swinging of the hook sleeve 451 until multiple limit plates 52 are all against the outer peripheral surface of the hook sleeve 451. At this time, the main reel 31 stops working, and the set limit plate 52 stops the swinging of the hook sleeve 451 and the hook 452, thereby shortening the swinging time of the hook sleeve 451 in the through hole.

[0037] When the main drum 31 rotates in the opposite direction, the suspension steel rope 32 and the hook steel rope 42 extend synchronously. Under the action of gravity, the hook sleeve 451 and the counterweight rod 53 are separated, and the counterweight rod 53 also slowly moves downward with the hook sleeve 451. The limit plate 52 unfolds and separates from the hook sleeve 451 to allow the suspended object to fall from the vertical direction.

[0038] Example 3: Reference Figure 8-Figure 9 , which is the third embodiment of the present invention. The limiting part 5 of this embodiment is different from that of the second embodiment, and the rest of the structure is the same as that of the first embodiment. The limiting part 5 includes a limiting ring 51 which is assembled in the hook frame 43. The limiting ring 51 is sleeved with a plurality of rotatable abutment plates 511. The damper 58 hinged at the bottom edge of the abutment plate 511 is fixed to the inner wall of the through hole. The rotating sleeve 56 is arranged in the through hole above the limiting ring 51 and rotates, the spiral rod 55 is engaged with the rotating sleeve 56, and the spiral rod 55 moves up and down for rotating the rotating sleeve 56. The spiral rod 55 is located on the outer wall above the rotating sleeve 56 and is wound with a reinforcing steel cable 57. The other end of the reinforcing steel cable 57 passes through the arc groove at the bottom end of the abutment plate 511 and is fixed on the abutment plate 511.

[0039] A plurality of abutment plates 511 are provided, and the plurality of abutment plates 511 rotate around the limit ring 51 to form an expanded or contracted state under the pulling of the reinforcing steel cable 57. The abutment plates 511 form a cylinder against the hook sleeve 451 in the contracted state. The reset plate connected to the top of the spiral rod 55 is connected to the limit ring 51 through a spring.

[0040] The rotating sleeve 56 can rotate around the limiting ring 51, and the rotating sleeve 56 does not move as a whole. When the hook sleeve 451 moves upward and presses against the spiral rod 55, the spiral rod 55 is pushed upward. During the upward movement, the spiral rod 55 pushes the rotating sleeve 56 to rotate. At the same time, the reset plate is also pushed upward by the spiral rod 55. The spring is stretched, and the rotating sleeve 56 rotates and rolls up the reinforcing steel cable 57. The reinforcing steel cable 57 pulls the bottom ends of the plurality of the abutment plates 511 to contract when the abutment plates 511 are rolled up. When the abutment plates 511 are contracted, the damper 58 is slowly stretched to keep the abutment plates 511 contracted. uniformity, and the damper 58 can also provide support for the end angle of the support plate 511. At the same time, the strengthening steel cable 57 can also provide support force for several support plates 511 to resist the collision impact force generated by the swing of the hook sleeve 451, until the support plate 511 contracts and presses against the hook sleeve 451, so as to ensure the clamping force of the hook sleeve 451 and shorten the swinging time of the hook sleeve 451 in the through hole. At the same time, the circle of strengthening steel cable 57 can also limit the hook steel rope 42 to prevent the hook steel rope 42 from moving to the back of the support plate 511 during the swinging process.
