The utility model provides a small flat car for uncovering a railway cover plate, aiming at solving the problems of large workload and high safety risk of uncovering the railway channel cover plate in railway public network covering engineering.
The utility model is realized by adopting the following technical scheme: uncovering railway apron small flatcar, the on-line screen storage device comprises a base, four corner positions of base are equipped with the wheel, wherein the diameter of two wheels of base one side is the same, the diameter of two wheels of opposite side is the same, the diameter difference of the wheel of both sides equals the difference between interior height, the outer height of weak current channel, still be provided with the support column on the base, the top of support column and the bottom of slant davit rotate to be connected, the top of slant davit is provided with the pulley, the bottom of slant davit still is fixed with the motor, the cylinder is connected to the motor, twine wire rope on the cylinder, wire rope's free end is walked around the pulley and is connected with the couple.
When the small flat car is used, the small flat car is pushed to the position of the weak current channel, the wheel with the small diameter is positioned at the position of measuring the inner height of the weak current channel, the wheel with the large diameter is positioned at the position of measuring the outer height of the weak current channel, the diameter difference of the wheels at two sides just balances the height difference of the inner height and the outer height, the small flat car is horizontal at the moment, when the cover plate is uncovered, the cover plate is hooked by a steel wire rope, a motor is started, the cover plate is lifted, the oblique suspension arm is rotated, the cover plate is placed at the edge of the channel, the optical cable immediately starts to be laid after the cover plate is uncovered, and after the optical cable is laid, the cover plate is restored to the original position by the small flat car.
Foretell take off and cover railway apron small flatcar, still be connected with 4 bracing on the support column, improve the structural strength of small flatcar bearing greatly.
The base of the small flat wagon for uncovering the railway cover plate is formed by welding 3 long channel steels and 5 short channel steels in a transverse and vertical mode.
According to the small flatcar for uncovering the railway cover plate, the top of the supporting column is provided with the stand column, the bottom of the oblique suspension arm is provided with the sleeve, and the sleeve at the bottom of the oblique suspension arm is fixedly sleeved on the stand column at the top of the supporting column, so that the oblique suspension arm is rotatably connected.
In the small flatcar with the cover-uncovering railway cover plate, the wheels are made of rubber.
In the construction of the cover plate of the weak current channel of the uncovered railway, a small flat car is used for replacing a manual mode, the cover plate is lifted, the optical cable is laid and then recovered in time, and labor cost and time cost are greatly saved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the base.
Fig. 3 is a side view of the base.
In the figure: 1-base, 2-wheel, 3-support column, 4-inclined strut, 5-oblique suspension arm, 6-motor and 7-steel wire rope.
Detailed Description
3 pieces of 2.3-meter long channel steel and 5 pieces of 1.5-meter long channel steel are transversely and vertically welded into a small flat car base 1, 4 pieces of 40-cm-long DN50 steel pipes are used as inclined struts 4, 1 piece of 55-cm-long DN200 steel pipe is used as a support column 3, the inclined struts 4 and the support columns 3 are welded into a small flat car bearing part, 3 pieces of long DN150 steel pipes and 10 pieces of 25-cm-long DN100 steel pipes are welded into a small flat car inclined suspension arm 5, and a motor 6 and a steel wire rope 7 are additionally arranged, as shown in figure 1.
The inner height and the outer height of a railway weak current channel are marked through early-stage field investigation, measurement and calculation, two rubber wheels are respectively manufactured, and the stability of the use process of the small flat car is ensured; measuring the width of the channel by using a measuring tape to determine the width of the small flatcar; the middle support column 3 greatly improves the weighing structural strength of the small flat car through the inclined struts 4 at four positions, and the expected effect is achieved.
The small flat car is used and operated:
1. and (5) enabling the small flat car to go up the road. The method comprises the steps of handling the recording procedures of the upper lanes of the small flat cars to a central dispatching room in advance, selecting the position with better road conditions, and pushing the small flat cars to the weak current channel.
2. And (6) uncovering the cover plate. When the cover plate is uncovered, the cover plate is hooked by a rope.
3. And starting the motor. After the cover plate is firmly sleeved by the rope, the motor is started to lift the cover plate and place the side of the channel.
4. And laying the optical cable. And after the cover plate is uncovered, the optical cable is laid immediately.
5. And (6) recovering the cover plate. And after the optical cable is laid, the cover plate is restored to the original position by using a small flat car.
The small flat car mainly has the following 4 technical characteristics:
1. the structure is simple. The small flat car is made of common steel, and is low in price and low in cost.
2. The operation is convenient. After the cover plate is firmly sleeved by the rope, the cover plate is hoisted by utilizing a hoisting device of the small flat car.
3. And the cost is saved. The small flat car reduces a large amount of manual operation, saves operation time, and is convenient to operate and high in efficiency.
4. The damage rate of the cover plate is reduced. The cover plate is manually uncovered for construction, and the cover plate can be greatly damaged in the cover plate uncovering process of the railway due to factors such as improper use of tools, physical strength and the like. The use of the small flatcar, the cover plate uncovering process is convenient, and the damage to the cover plate is greatly reduced.
