Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a so-called method for constructing carpets, long flooring materials, etc. as indoor floor finishing materials on concrete ceiling slabs without a mortar base. Concerning the concrete floor finishing machine for smoothing the concrete floor surface after concrete pouring and compaction and removal of water seeping from the surface in construction work called concrete floor finishing, please refer to the following for more details. ! This invention relates to a concrete floor finishing machine equipped with a device for smoothing the surface of a concrete floor in a semi-solidified state.

[Conventional technology]

Concrete mentioned above) 11! ! In finishing work,
Conventionally, plasterers use a mantle to finish the work while observing the hardening plate on the concrete floor surface, or they ground several finishing rods that are rotated by an engine installed in the main body on the concrete floor surface. A finishing machine (product name: Nitrowell) is used to carry out semi-finishing while the worker holds and moves the handle extending from the main body.
After that, methods such as plastering with a trowel finish were used. However, when using the above conventional method, not only does the plasterer need to be skilled, but the concrete hardens slowly, especially in the winter, so the work takes a long time, and the working conditions may become harsh. . In addition, in the latter case, when the finishing machine is dispatched, the finishing machine is grounded and the main body is pulled by the handle, and the ground reaction force of the finishing m1-shaped body is used to perform the process. The steering operation is difficult, and the concrete surface is easily damaged when steering.
Furthermore, the vibrations of the engine are transmitted to the worker, and if the worker continues to work for a long time, there is a risk that the worker will become fatigued.

Therefore, as shown below, 12 proposals have been made in which concrete floor finishing is performed using a finishing device attached to a self-propelled vehicle body.

A pair of crawler traveling devices are installed at the front and rear of the aircraft, and a plurality of finishing trowels rotate around the axis approximately at the center of the pair of traveling devices. A J position is provided (for example, see Japanese Patent Application No. 58-212892).

However, when using the concrete floor finishing machine of the earlier patent application mentioned above, it was possible to finish the concrete floor with considerable accuracy and reduce worker fatigue; however, as described below, There was a wide range that caused such inconveniences, and there was room for improvement.

In other words, when traveling during work, traces of the traveling equipment located at the rear of the finishing equipment remain, so in order to erase these traces, it is necessary to install a leveling device such as a leveling body further behind the traveling equipment. This caused an increase in the weight of the aircraft, which tended to result in poor finishing due to the aircraft sinking on unhardened concrete floors. Furthermore, the leveling tool did not erase traces of passage very well.

On the other hand, since the structure has a finishing device between a pair of traveling devices, the finish by the finishing device is
R was small. Furthermore, since space is required for moving the running equipment, especially for floor slabs 'Q'W+
However, depending on the finishing machine, large areas of uneven finishing tended to remain, and manual finishing was still required to a large extent.

[Problem that the invention seeks to solve]

In view of the above-mentioned practicalities, the aim of the present invention is to improve the accuracy (and save labor) of finishing the concrete floor.

(Measures to solve the problem fi1) The structure of the concrete floor 1J-upper machine according to the present invention f2 is that a finishing device for smoothing the semi-solidified concrete floor surface is disposed on the outside of the traveling device, and , a driving mechanism is provided for rotating the finishing device around the travel 211, and its effects are as follows.

(Function) In other words, there is a finishing device on the outside of the traveling @jL'Il, and the finishing device rotates around the traveling device, so the finishing range caused by the finishing device can be made larger compared to the entire aircraft. . Furthermore, this finishing machine can finish the edges of the floor slab without considering the space for movement of the traveling device, significantly reducing the portions that require manual filter finishing. I can do it.

Furthermore, since one of the traveling devices conventionally provided at the front and rear can be omitted, the transmission mechanism can also be simplified. Also,
Traveling by VT setting! ! Since the marks are self-erased by the 1!1 rotation of the finisher d, there is no need to provide a separate leveling step that was conventionally required.

Furthermore, since the traveling device and finishing device work together to support the machine on the ground during work, the traveling device itself is also small! ! We should be able to turn it into an IT system.

〔Effect of the invention〕

As a result, work efficiency can be improved, and
It is now possible to reduce the number of personnel required for concrete floor finishing work, shortening work time, and
It has become possible to reduce costs by reducing labor costs.

In addition, since the fuselage ff1ffi can be made smaller than the conventional one, there is less chance of finishing defects caused by sinking of the fuselage on the unhardened concrete floor surface. The finishing equipment itself erases the finish on the concrete floor surface.
I was able to do it well 1.7 times.

It's easy to do direct finishing work on concrete floors as part of your work or as a break! ! I made 7 songs so that I could do it under the best conditions, extremely efficiently, and with good accuracy.

〔Example〕

The present invention will be described in detail below based on the drawings.

A pair of left and right crawlers run at 1° as shown in Figures 1, F, and 3! The main body (1) equipped with J11 (A) has a finish 'J2 i1?' for smoothing the concrete floor surface. -CB)
This is a concrete floor finishing machine that is used for concrete floor finishing work by connecting the two.

Both crawler traveling devices (A) each have a drive 9) attached to both ends of the vehicle body (1), a wheel body (2) and a main idle wheel body (2).
3), and the pickles stretched across both wheels (2) and (3)! l! ! The left and right drive transport bodies (2) consist of an endless belt-like body (4) made of rubber with flat sides.
) are interlocked and connected to separate forward and reverse traveling motors (5), and are configured so that the aircraft can move forward and backward and change direction by combining the forward and reverse directions of both motors (5). . In addition, at the # rear intermediate part of both wheels (2) and (1), a lever-shaped body (6) extending downward from the vehicle body (1) is attached to the inner circumferential surface of the belt-shaped body (4) on the ground contact side. The crawler traveling device (A) is placed in contact with the ground over a wide area to prevent the aircraft from sinking into the concrete I-surface that has not hardened yet. C11 (4a) is a scraper for scraping off concrete that has rained on the outer peripheral surface of the belt-like body (4).

In addition, the finishing device (B) 1, as shown in FIGS.
In plan view, from the center of the vehicle body (1)
! ! It is attached to the tip of a pipe frame (8) made of rich pipes arranged radially with a phase difference of 9G' towards the center. A circular pipe frame (
19) are bolted together via support rods (20) to the tip side of the pipe frame (8) to which each section (7) is attached, and when finishing the concrete floor while moving, the hIv This is to prevent the body () and other components from colliding with other objects.

As shown in FIG. 5, each layered body (7) is attached so as to be movable laterally around the horizontal axis CP+ via a bracket (9) fixed to its upper surface. Then, this bolt (11) is screwed into the NAND (10) welded to the pipe frame (8) (by rotating the bolt).
The bracket (9
) are rotated four times around the axis $(P+), so that the shield (7) can be set at any angle with respect to the concrete floor surface. Also, i! in bracket (9)! The degree of inclination of the layered body (7) can be visually checked by the scale (21) on which the provided pointer (9a) is located.

It is attached to a spherical pressure receiver (14) externally fitted on the finishing device side cylindrical body (13) in an up-down position so as to be able to move up and down, so as to be relatively rotatable around the axis (P,). Then, a plug 7) (16) to which a pair of rod-shaped bodies (15) are fixed, sandwiching one pipe frame (8) from both sides, is fitted onto the cylindrical body 13) so as to be relatively rotatable. At the same time, this platen (16) is interlocked and connected to the motor (17) attached to the cylindrical body (13) via a reduction gear 1t4 (18), and the (ii) rotation of the motor (17) ,
Various shapes ()) are I' of the vehicle body (1)! I12! The concrete floor is rotated to smooth the surface of the semi-solidified concrete floor.

The finishing device side cylindrical body (13) is attached to the car body @ cylindrical body (22) vertically fixed vertically at approximately the center of the car body (1), and the two cylindrical bodies (13) and (22) are slid relative to each other. externally fitted via a linear bearing (23) that allows movement;
Then, the bracket (24) is attached to the finishing device @ cylindrical body (13).
), and the head part (25a) is fixed to the vehicle body (1).
25), both the cylindrical bodies (!3) and (22) are erected relative to each other, and the vehicle body (1) and the part 1-device (n) are moved up and down relative to each other. .

Then, this concrete floor f'', 1, uses the above-mentioned slow setting tank construction of both cylindrical bodies (13) and (22), and the linear 7-speed motor (25) to change the direction of the aircraft. It is now possible to do so. In other words, when changing the direction of the aircraft, first, each string-like body (7) is grounded on the concrete floor surface, the body is supported by the legs of the string-like body (7) at 4Cli, and the 7-domain motor (25) is operated linearly. The vehicle body (1) is raised relative to the finishing device (B). In this state, when the finishing device rotation motor (17) is operated,
Conversely, it moves around the vehicle body (1) side or around the axis (P8). When the car body (1) faces a predetermined direction, the finishing ff1 rotation-motor 7) is stopped, and the 7-d motor (25
), the vehicle body (1) is lowered to the concrete floor surface, completing the direction IA of the vehicle.

Therefore, compared to the case where the direction change of the aircraft is performed simply by the difference in moving speed between the left and right crawler traveling devices (A), it is possible to turn the aircraft with almost no IR damage on the concrete floor surface caused by the direction change. This can be done in a small radius, and the aircraft can be accurately moved to a predetermined position.

The shape, mounting structure, or number of the trowels (7) constituting the finishing equipment U (B) are subject to change.For example,
The trowel-shaped body (7) itself may rotate around the main body (ri) while rotating on its own axis. Also, in order to rotate the finishing sheath Z (B) around the main body (1), the above implementation may be necessary. In the example, instead of the finishing equipment rotation motor (17), the rotor is built into the circular coupling (12) to which the pipe frame (8) is attached, and the stator is built into the spherical catch (14). , this connection structure itself may constitute a motive force (they are referred to as a drive f!i structure (17) for rotating the finish 2 Z (11)).

Pressure force by each immersion body (7)! It! The configuration for IT can be modified in various formats, for example, a concrete hardness detection device consisting of a load cell and a steel rod attached to the tip of the load cell is installed, and an X rod is placed in a semi-solidified concrete floor. The load required to penetrate concrete for a certain length can be detected by a load cell, and the appropriate pressing force can be determined and displayed based on the number of detected loads, or the appropriate pressing force determined by this concrete hardness detection device can be The pressing force value and the pressure value indicated by the pressing force adjustment load cell (31) are respectively input into the 1lIa circuit of the linear heft motor (25), and this motor (25) automatically adjusts the pressing force! It may be configured to perform section J1. Also, it is also possible to use various pressure sensors instead of the load cell (31) to confirm the pressing force.

Left and right - Instead of the phantom crawler traveling device (A), several drive rollers may be provided on each of the left and right sides (and they are set at t = 1).
It is called 〒2-oki (A).

Furthermore, a receiver is installed in place of the relay box (34) in the previous embodiment, and the 4W signal from the transmitter held by the worker is sent to this receiving machine using radio to perform operations with the machine. Alternatively, the finishing machine is equipped with a position ff pinch sensor to recognize the current position, and the work is performed while determining the travel route based on the conventional information from this sensor and the hardness detection device (32). The method of eye operation can be changed as appropriate, such as performing a fully automatic operation such as advancing the screen.
