Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the above technical solutions will be described in detail below.
Relates to a pillow changing method for greatly improving pillow changing efficiency and eliminating personal safety hidden dangers,
1. two persons in cooperation are arranged in advance to check or wash the screws of the I type, II type and III type new cement pillows to be replaced, then the prepared spring boxes are installed, and the spring cushion nuts are fastened firmly;
2. simultaneously, two persons are arranged to remove nuts, fasteners, elastic strips and nylon cushions of I-type, II-type and III-type old pillows or damaged pillows to be replaced, and 20 persons are generally used as the best;
3. after the skylight point is started, an operator of the multifunctional operation vehicle normally takes off a ballast opening under the command of a safety commander, extracts an old sleeper, extracts three old sleepers, extracts a fourth old sleeper in a rotating mode, the rotation aims to improve the efficiency, after 5 th to 7 th old sleepers are extracted, puts a prepared new sleeper into a track bed in the same rotating mode, operates a button by the operator, turns down a special hydraulic clamp to perform rapid inward pressurization movement, rapidly pushes out a spring steel plate with the thickness of 8 mm in a newly-replaced I, II and III type cement sleeper spring box, and enables the spring steel plate to extend about 40 mm to 60 mm along the inclined plane of a steel rail 4: 1; under the elasticity of the spring steel plate, the cement sleeper tightly presses the inclined plane of the steel rail, so that the cement sleeper and the steel rail are ensured to be integrated;
4. after the manipulator finishes, continuously taking out an old pillow in a rotating mode, replacing the old pillow with a new pillow, clamping in the same mode, and circulating;
5. along with the constantly new pillow that trades of multi-functional operation car, the cement pillow that newly trades removes backward gradually, after waiting to shift out and push away the tiny fragments of stone, coal, etc. board, install four sets of hydraulic pressure rotary steel wire brushes that push away on the tiny fragments of stone, coal, etc. board and begin work, the tiny fragments of stone, coal, etc. board that will take off is piled up the railway ballast around the spring box and is cleaned totally, the aforesaid two cooperation personnel of solving old pillow bolt, fastener, bullet strip, nylon pad etc. tear the spring box open rapidly to a whole set of rail fasteners such as fastener, flat pad, bullet strip, nylon pad that will prepare are installed, whole work is ended.
The spring box mounting method comprises the following steps: four spring boxes are installed in advance on a new pillow to be replaced, the spring boxes are installed on four screw rods respectively, spring pads are additionally installed, nuts are installed, and a kilogram wrench is used for tightening the nuts. The spring box is provided with a spring steel plate with 8 mm, the spring box is fixed by four screws with 5 mm in a penetrating way, and elastic allowance of 2 mm-4 mm is arranged between the screws and the nuts; the spring steel plate can move about 60 mm under the action of external force, namely, the spring steel plate extends about 40 mm-60 mm along the inclined plane of the steel rail 4: 1. In order to reduce the weight of the spring case, the spring case may be made of aluminum alloy.
When the sleeper is replaced, two special hydraulic clamps are respectively added at two ends of the sleeper clamp, the direction of each special hydraulic clamp is vertical to the sleeper clamp, when the sleeper clamp puts a newly replaced cement sleeper in place, the two sets of hydraulic clamping devices are turned down at 90 degrees, the clamping heads are aligned to the position of the spring steel plate, and the spring steel plate moves inwards rapidly under pressure, so that the spring steel plate extends by about 40-60 mm along the inclined plane of the steel rail 4: 1; under the elastic force of the spring steel plate, the cement sleeper tightly presses the inclined plane of the steel rail.
Because the ballast removing plate needs to continue sleeper replacement, the rear ballast covers the front cement sleeper and covers the four spring boxes, and therefore the fasteners, the nylon pads, the elastic strips and the like are inconvenient to replace at the rear. Therefore, the steel plate needs to be cleaned, and four sets of hydraulic rotary steel wire brushes (adopting thicker steel wires with the diameter of 20 mm) are arranged above the ballast pushing plate; when the railway ballast covered on the cement sleeper exceeds the surface of the railway track, the ballast pushing plate is pushed to be flat; the rest railway ballast is cleaned under the action of the four sets of hydraulic rotating steel wire brushes, and the fasteners, the nylon pads, the elastic strips and the like are convenient to replace.

2. compared with the pure manual pillow replacement, the efficiency is obvious; taking a 3-hour skylight as an example, the pillow changing equipment of one multifunctional operation vehicle can only work for 2 hours, about 120 to 180 pillows are changed (calculated according to 150), 6 people (one manipulator, four coordinators and one commander) are invested, and 25 people are all used; the pure manual pillow replacement can work for 2.5 hours (2 people per hour), and each person replaces about 5 pillows;
3. because the matched personnel do not work under the pillow changing device of the multifunctional working vehicle, the potential safety hazard of the personnel is thoroughly solved, the long-time high tension of the operating personnel is avoided, and the fatigue is reduced;
4. the cooperation personnel can enter and exit from the lower part of the pillow changing device of the multifunctional working vehicle, so that the working strength of the cooperation personnel is greatly reduced, and the cooperation personnel can work orderly behind the pillow changing machine;
5. the pillow replacement cost is reduced, and the space is large;
6. due to high pillow changing efficiency, the pillow changing machine can replace manual pillow changing in a large amount and adapt to a large amount of pillow changing operations in a cluster mode;
7. when the square sleepers are used for stringing the sleepers, the operation of stringing the sleepers can be accelerated, so that the operation of stringing the square sleepers is comprehensively improved by about 15 percent.
