Description

[Detailed description of the invention] (Field of industrial application) The present invention is a self-propelled vehicle for removing flooring materials, and more specifically, a self-propelled vehicle for removing flooring materials that can easily peel off a large number of flooring materials stuck to a floor surface. Regarding self-driving cars.

(Prior Art) Conventionally, as this type of floor material stripping apparatus, there exists, for example, the one described in Japanese Patent Application Laid-Open No. 51-64735.

That is, as shown in Fig. 3, this conventional method
A peeling blade 35 having a predetermined inclination angle with respect to the flooring material is provided on the traveling side of the self-propelled vehicle main body 20 so as to be swingable back and forth in order to peel off the flooring material.

When using the peeling blade 35, the peeling blade 35 is inserted into the boundary between the floor surface and the flooring material.
While swinging the robot 5 back and forth, the flooring is sequentially peeled off using the propulsive force of the self-propelled vehicle.

Since this flooring stripping device is configured to be self-propelled, it has the advantage of being able to quickly strip the flooring using the propulsion force.

(Problem to be solved by the invention) By the way, in order to effectively peel off the flooring, it is necessary to first enter the peeling blade 35 into the boundary between the floor surface and the flooring and start the peeling operation, as described above. but,
Due to its relationship with the floor surface, flooring materials are not necessarily bonded in a uniform plane, and usually have some unevenness. Therefore, it is necessary to move the peeling blade 35 into the boundary portion according to the unevenness.

However, the above conventional method simply uses the peeling blade 35.
Since the stripping blade 35 only swings back and forth, it is extremely difficult to move the tip of the stripping blade 35 into the boundary area according to the unevenness of the flooring material, and therefore the stripping blade 35 does not touch the floor surface. This has the serious disadvantage of slipping, digging into the floor surface, or having its tip come into contact with the side of the flooring material, resulting in part of the flooring material remaining on the floor surface and being peeled off. It was. Therefore, the remaining flooring has to be peeled off again, which poses a problem in that complicated post-treatment work is required.

In addition, when peeling, the peeling blade 3
5 into the floor material and floor surface, remove the peeling blade 3.
The self-propelled vehicle is moved forward while rocking the base material 5 in the forward direction, and the flooring is sequentially peeled off. With conventional products that peel off uniformly, for example, if a self-propelled vehicle is forced to move against a strongly bonded flooring, the self-propelled vehicle itself may lift, creating an extremely dangerous situation during work. It also had the fatal problem of causing.

In other words, the conventional method was not able to perform appropriate peeling work depending on the adhesion state of the flooring material.

Therefore, the present invention was devised to solve the above-mentioned conventional problems, and is an easy-to-handle material that can be peeled off appropriately depending on the state of adhesion of the flooring material adhered to the floor surface. The object of the present invention is to provide a self-propelled vehicle for stripping flooring.

(Means for Solving the Problems) That is, in order to solve the above problems, a driver's seat 16 is provided in a self-propelled vehicle body 20 capable of self-propelled, and a floor material is provided on the traveling side of the self-propelled vehicle body 20. A peeling blade 35 having a predetermined angle of inclination with respect to the floor surface to peel off the
However, in a self-propelled vehicle for floor material stripping which is provided so as to be swingable back and forth by a pushing means, in order to be able to adjust the inclination angle of the stripping blade 35, the stripping blade 35 is provided with a swing at its tip. This is a self-propelled vehicle for flooring stripping, in which a frame having a movable arm 34 pivoted thereon is swingably provided around a fulcrum B, and is provided with means for swinging the frame.

(Function) Therefore, in the self-propelled vehicle for floor material stripping having the above-mentioned configuration, the frame formed by pivoting the swinging arm 34 having the stripping blade 35 at the tip is attached to the fulcrum B.
Since the frame is provided so as to be able to swing freely around the frame, and is provided with a means for swinging the frame, first, at the beginning of peeling, by swinging the frame, the The peeling blade 35 can be easily placed at the boundary between the floor material and the floor surface. Therefore, for example, it becomes possible to deal with peeling of flooring material that has been adhered in an uneven manner, and it becomes possible to start the peeling work extremely well.

Furthermore, even during peeling, by adjusting the movement of the peeling blade 35 according to the adhesion state of the flooring material, the approach angle, approach force, adhesion force, etc. of the peeling blade 35 to the floor surface can be subtly adjusted. It is also possible to individually deal with peeling of flooring materials that have varying adhesion conditions.

Reference numeral 18 denotes a lever erected in an inclined manner on one side of the tip end of the upper surface of the base 2, and the lever 18 can be moved up and down on the tip end side of the tip frame 13 via a connecting rod 19. The self-propelled vehicle main body 20 is configured as described above.

Reference numeral 21 indicates a fourth pulley having two grooves, which is pivoted on one side of the center portion of the upper surface of the tip frame 13, and the first groove of the fourth pulley 21 has the second groove.
The third groove of the pulley 5 and the belt 22 are stretched over each other. Reference numeral 23 indicates an eccentric crank vibration section provided at the center of the lower surface of the tip frame 13, and the eccentric crank vibration section 23 has a body section 24 connected to both end sections 25 in an eccentric state as shown in FIG. A fifth pulley 29 is attached to one end of the shaft 26. The fifth pulley 29 is formed by spanning the second groove of the fourth pulley 21 and the belt 28. Further, a cylindrical body 31 is fitted onto the body 24 of the shaft rod 26 via rolling elements 30, and the outer peripheral surface of the cylindrical body 31 is reciprocated in the front-rear direction by passing through a vibrating housing 32. A pushing body 33 is protrudingly guided, and the tip of the pushing body 33 is bulged.

34 is a support shaft A at the tip of the tip frame 13.
The figure shows a swinging arm which is tilted and pivoted toward the self-propelled vehicle body 20 through the swing arm, and two peeling blades 35 are provided at the lower end with their cutting edges 36 protruding downward at a constant angle of inclination. In addition, a receiving portion 37 is formed on the back surface of the swinging arm 34 so that the tip of the pushing body 33 can be struck.

The self-propelled vehicle for removing flooring materials of this embodiment has the above-described configuration, and next, this self-propelled vehicle 38 is used to peel off a large number of flooring materials 40 such as plastic tiles pasted on the floor surface 39. Let me explain the case.

First, when a worker gets into the driver's seat 16 of the self-propelled vehicle 38 and operates the driving operation lever 17 to start the prime mover 1, the first pulley 4 rotates and the second and second pulleys are rotated via the belts 6 and 8. As the third pulleys 5 and 9 rotate, the wheel 1 pivoted on the transmission 7
0, the crawler 15 rotates and the self-propelled vehicle 38
moves forward. At the same time, due to the rotation of the second pulley 5, the fourth
The fifth pulleys 21 and 29 rotate, and the shaft rod 26 within the eccentric crank vibration section 23 rotates.

At this time, since the body 24 of the shaft 26 is eccentric, the cylindrical body 31 externally fitted onto the body 24 via the rolling elements 30 reciprocates the pushing body 33 in the front and back direction, causing the pushing body 33 to reciprocate in the front and back direction. Swing arm 34 at the tip of moving body 33
This results in continuous impact on the receiving portion 37 of the ball.

As a result, the swinging arm 34, which is pivotally attached to the tip of the tip frame 13 with an inclination toward the self-propelled vehicle main body 20, is intermittently pressed in the traveling direction about the support shaft A, and the swinging arm The cutting edge 36 of the peeling blade 35 provided at the stripping blade 34 is vibrated at an acute angle with respect to the flooring 40 while in contact with the flooring 40. Therefore, when the cutting edge 36 of the peeling blade 35 enters between the adhesive surfaces of the floor material 40 and the floor surface 39, the cutting edge 36 moves forward due to the forward propulsive force of the self-propelled vehicle 38 and the impact of the pressing body 33. It moves back and forth while being pressurized, and is deeply inserted between the floor material 40 and the floor surface 39 while being in close contact with the floor surface 39, so that the floor material 40 is rolled up smoothly and reliably by the peeling blade 35. It can be peeled off.

In this case, when the lever 18 is pulled forward, the distal end side of the distal end frame 13 swings around the support shaft B via the connecting rod 19 and is lifted up somewhat, and when the lever 18 is pushed forward, the distal end frame 13 13
The tip side of the peeling blade 35 is lowered, and the angle of inclination of the peeling blade 35 with respect to the floor material can be adjusted. Therefore, by operating the lever 18, the cutting edge 36 of the peeling blade 35 can enter the boundary between the floor material 40 and the floor surface 39 via the tip frame 13 and the swing arm 34.

This makes it possible to deal with, for example, the floor material 40 that has been pasted with unevenness by adjusting the inclination angle by moving the peeling blade 35 up and down according to the unevenness, making the peeling work extremely easy. It can be started immediately.

Also, during peeling, the peeling blade 3
Since it is possible to finely adjust the approach angle, approach force, and adhesion force to the floor surface of the floor material 40 of No. , variations in the adhesion state of the flooring material 40 can also be dealt with favorably.

In this way, there is an advantage that the peeling work of the flooring material 40 can be performed more reliably and quickly by simply operating the lever 18.

Furthermore, during the stripping work of the flooring material 40, the stripping blade 35 is subjected to resistance due to the flooring material 40, but in this embodiment, the self-propelled vehicle 38 is difficult to slip because it runs on the rubber crawler 15. Therefore, the stripping work can be carried out reliably, and there is no inconvenience such as leaving marks of the crawler 15 on the floor surface 39 after the floor material has been stripped and causing damage.

In the above embodiment, the eccentric crank vibrating section 23 using an eccentric shaft and the swinging arm 3 are used as pushing means for swinging the cutting edge 36 of the peeling blade 35 back and forth.
However, the present invention is not limited to this, and instead of the eccentric shaft, an eccentric cam, a slider crank mechanism, etc. may be used, or it may be operated via a hydraulic pump. It is also possible to use a hydraulic motor or the like, and the specific configuration of this pushing means is not critical.

Further, in this embodiment, the crawler 15 is used to make the self-propelled vehicle main body 20 run, but the present invention is by no means limited to this, and it may be configured with tires, etc., for example.

Furthermore, the prime mover 1, which is the driving means of the self-propelled vehicle body 20, is not limited to the gasoline engine of the above embodiment, but may also be configured with an electric motor or the like.

Further, the peeling blade 35 does not necessarily have to be constructed by connecting two blades as in the above embodiment, and may be, for example, a single blade, and its specific configuration is not limited.

Furthermore, in this embodiment, the self-propelled vehicle body 20
Although the movement of the peeling blade 35 and the back-and-forth swinging of the peeling blade 35 are linked, the present invention is by no means limited to this, and it is of course possible to configure the two to operate independently.

Further, in the above embodiment, the tip frame 13 is swung by operating the lever 18, but the specific means for this is by no means limited to this, and for example, a hydraulic cylinder or the like may be used. In short,
It is sufficient that the frame formed by pivoting the swinging arm 34 having the peeling blade 35 at its tip can swing around the fulcrum B.

In addition, the specific configuration of each part, such as the shape of the self-propelled vehicle body 20, can be changed as desired within the scope of the present invention.

The present invention can be widely applied to flooring materials such as long plastic sheets and cushion sheets in addition to the plastic tile flooring material of the embodiment.

(Effect of the invention) As mentioned above, the present invention has a frame formed by pivoting a swinging arm with a peeling blade at the tip,
Since the frame is provided so as to be able to swing freely around the frame, and is provided with a means for swinging the frame, first, at the beginning of peeling, by swinging the frame, the The peeling blade can be easily placed at the boundary between the flooring material and the floor surface. Therefore, it is now possible to deal with the peeling of flooring materials that are stuck in an uneven manner, which was impossible with conventional devices that simply swing the peeling blade back and forth. It was effective.

In addition, even during stripping, by adjusting the movement of the stripping blade according to the adhesion state of the flooring material, the approach angle, approach force, and adhesion force of the stripping blade to the floor surface can be finely adjusted. It also has the unique effect of being able to deal with variations in the adhesion state.

As a result, inconveniences such as lifting of the front end of the self-propelled vehicle can be avoided, and the flooring removal work can be performed reliably and quickly without leaving the flooring on the floor surface.
