Description

A roadbed waterproof layer shovel vehicle

technical field

The invention relates to a construction machine, in particular to a roadbed waterproof layer shovel vehicle.

Background technique

The first generation of my country's high-speed rail line has been in operation for nearly ten years, and the subgrade of some lines has warped or even fallen off the waterproof layer, which easily interferes with the vision of high-speed rail drivers and poses a safety hazard. Therefore, the railway department requires that the original waterproof layer be completely Remove, re-build and lay. Since the high-speed railway lines are laid on viaducts, the subgrade area is relatively closed and there is not much space. Therefore, the existing large and medium-sized forklifts cannot enter the high-speed railway foundation for operation, and can only rely on manual removal. And in order not to affect the normal operation of the high-speed rail, the window period for on-site construction is only four hours between 0:00 and 4:00 a.m., so the construction unit has to increase manpower, which leads to high labor costs and low work efficiency. Therefore, it is necessary to design a small-scale eradication equipment that can be used in the high-speed railway base area to replace labor and improve the construction progress.

Detailed ways

The specific structure of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, and Figure 3, the generator 1 is used to provide power, the output voltage is 380V, the AC motor 2 is used as the power output, and the worm gear reducer 3 and the chain transmission device include a small sprocket 4 and a chain 5 , the large sprocket 6 is used for deceleration transmission, the worm gear reducer 3 is fixed on the forklift bracket 7, the large sprocket 6 is installed on the crank 9, and the crank 9 crank is connected to the symmetrical crank 24 through the cross bar 23 to form an output end, symmetrical Crank 24 is installed on bearing seat 8, and bearing seat 8 is then fixed on forklift support 7. One end of the connecting rod 10 is connected with the middle section of the crank 9, and the other end is connected with the middle section of the blade push rod 11. The two ends of the blade push rod 11 are respectively inserted into the central hole of the push rod slider 12, the push rod slider 12 is installed inside the guide rail 13, and the guide rail 13 is fixed on the front end of the forklift bracket 7. In the middle of the blade push rod 11, several movable blade rods 14 are loaded into simultaneously, and the end of the blade rod 14 is then fixedly connected with the blade 15.

In addition, inside the guide rail 13 , away from the front end of the push rod slider 12 , there is placed a pressing rod slider 16 , and the pressing rod slider 16 is connected to the push rod slider 12 through a slider connecting rod 17 . The two ends of the pressure rod 18 are inserted into the pressure rod sliders 16 on both sides, and the movable compression spring mounting seat 20 is inserted into the middle part of the pressure rod 18, and the movable compression spring mounting seat 20 is inserted into the part of the blade rod 14 close to the blade 15 at the same time. The compression spring mounting seat 20 of the compression spring is installed and aligned with the compression spring on the depression bar, and between the two compression spring mounting seats 20, a compression spring 19 is installed. Fixed casters 21 and movable casters 22 are respectively installed at the bottom of the forklift frame.

During operation, place the shovel in the area where the waterproof layer is to be removed, first peel off the waterproof layer with a tool, and then push the shovel so that the blade of the shovel 15 enters between the waterproof layer and the roadbed. Start the generator 1, turn on the power switch of the AC motor 2, the output speed of the motor is 1400r/min, through the worm gear reducer 3 with a reduction ratio of 50 and the sprocket drive 4, 5, 6 with a transmission ratio of 2, the crankshaft 7 is driven at 14r Rotating at a speed of 1/min, the connecting rod 10 drives the blade push rod 11 and the push rod slider 12 to make a reciprocating linear motion. The pressure rod slider 16 moves synchronously with the push rod slider 12, so the pressure rod 18 and the blade push rod 11 also move synchronously, which ensures that the compression spring 19 between the above compression spring mounts 20 can always align the blade rod 14 Keep the pressure so that the shovel blade 15 fixedly connected with the shovel bar 14 is always in contact with the roadbed surface to adapt to slight changes in the slope of the roadbed surface. The waterproof layer within the stroke can be eradicated by the shovel back and forth once. The operator can push the shovel forward at the same time according to the linear speed converted from the crank speed and the specific stroke to realize the continuous peeling and eradication of the waterproof layer, and then the rest of the personnel Collect the shoveled waterproofing layer at the back. The designed working speed of this product is 4.2m/min, so it can remove 1km of waterproof layer by working four hours a day, and its working efficiency is much higher than that of manual removal progress of 100m/day.

The above specific embodiments are used as explanations of the present invention, and equivalent transformation thereof still falls within the protection scope of the present invention.
