Description

[Detailed description of the invention] The present invention relates to a vehicle body tilting device for pouring low-slump concrete, and more specifically, a mixer truck enters from an inclined approach provided at the front end of the base and is placed on the pedestal. The present invention relates to a vehicle body tilting device for pouring concrete, which tilts the frame using a driving device such as a hydraulic cylinder to efficiently discharge and pour low-slump concrete from a mixer.

Conventionally, when attempting to place concrete with low slump and large aggregate diameter, it was not possible to efficiently discharge low slump concrete with the concrete discharge capacity of the mixer truck alone, so slopes were constructed near the pouring site. Then, the mixer truck itself is tilted by entering the slope. In other words, the slope of the mixer was used to discharge low slump concrete.

According to this discharge method, it is not always possible to secure a slope depending on the site conditions, and there are many inconveniences such as the inclination angle of the slope cannot be adjusted or varied once it has been constructed.

In addition, the mixer truck itself may be modified to perform drum dumping, or a special model equipped with an ejector discharge function may be adopted, but in both cases, the mixer truck itself is special and cannot be used for other concrete pouring. It lacks versatility, such as not being able to be used for many purposes, and is extremely expensive.

Furthermore, low slump concrete was stored in buckets and transported to the pouring site using a trolley for transporting buckets, but depending on the road conditions, the load could spill, and during transportation, consolidation or aggregate It was causing separation.

Therefore, the present invention was developed to solve the above-mentioned problem that occurs when placing low-slump concrete.By tilting the pedestal via a drive device, the mixer truck itself on the pedestal can be tilted arbitrarily. The outline of this device is to efficiently discharge and place low slump concrete based on this inclination.

EMBODIMENT OF THE INVENTION Hereinafter, the vehicle body tilting device for concrete pouring according to the present invention will be explained in detail based on the drawings.

FIG. 1 is a front view of the vehicle body tilting device for pouring concrete according to the present invention.

This tilting device includes a base 1 made of, for example, a rectangular H-beam steel, a tilt approach 2 placed at the front end 11 of the base 1, and a tilt approach 2 that rotates to the rear end 12 of the base 1 via a pivot a. It consists of a frame 3 which is movably attached.

The inclined approach 2 arranged at the front end 11 of the base 1 has a gradual upward slope from above the ground, and the front end 11
The uppermost end in contact with the frame 3 is configured to be substantially flush with the upper surface of the pedestal 3. Furthermore, since the mixer truck is placed on the pedestal 3 via this inclined approach 2, the structure has sufficient strength.

On the other hand, at the rear end 12 of the base 1, a pivot a is connected via a bearing 13 and a bracket 31 attached to the pedestal 3.

That is, when the pedestal 3 is rotated upward by the hydraulic cylinder 4 and the position sensor 52 is turned on, a stop device is actuated by this sensor signal and the drive of the hydraulic cylinder 4 is stopped.

On the other hand, the pedestal 3 rotates downward and the position sensor 53
When turned on, this sensor signal activates the stop device as described above, and the hydraulic cylinder 4 is stopped.

As a result, the front end 11 of the pedestal 3 becomes substantially flush with the inclined approach 2.

Furthermore, stop plates 6, 6 for stopping the rear wheels of the mixer car from the front are pivotally mounted approximately in the center of the pedestal 3, that is, in the centers of steel car plates 35, 35, which will be described later, so that they can be turned upside down. .

A hydraulic cylinder 6 is mounted on the underside of the pedestal 3.
1 and 61 are fixed at one end 62 and 62, and rods 63 and 63 at the other end are connected to stop plates 6 and 6, respectively.

Therefore, as will be described later, when the operation panel is turned on, the rods 63, 63 of the hydraulic cylinders 61, 61 extend, rotate the stop plates 6, 6 in a predetermined direction, and stand up on the steel car plates 35, 35. let

Also, when the same OFF is done, the rods 63 and 63 are reduced,
The stop plates 6, 6 are rotated and drawn toward the lower surfaces of the steel car plates 35, 35, respectively.

In other words, these roadways 21, 21 and vehicle plates 35, 35
The front end 11 of the base 1 forms the same surface with no difference in level, and is configured so that a mixer truck entering from the inclined approach 2 can be smoothly placed on the pedestal 3.

Further, the walkway 7 is provided with a control panel 71 for operating the driving equipment of the tilting device, and an operation panel 72 for driving the hydraulic cylinder 61 for inverting the stop plates 6, 6.

FIG. 3 shows the right side of the tilting device.

A pedestal 3 is arranged on a base 1, and the pedestal 3 is tilted about a pivot a by hydraulic cylinders 4, 4. An inclination angle adjustment stopper 5 is provided to prevent this inclination from exceeding a certain angle.

Wheel stops 34, 34 are protruded from the mount 3 on the rear end 12 side of the base 1. Further, various control devices and a pump unit 73 are housed in the lower part of the walkway 7.

At this time, the inclination of the pedestal 3 is adjusted by the inclination angle adjustment stopper 5 to ensure the necessary inclination angle. Moreover, when the maximum inclination angle is reached, a stop device is activated to prevent the tilt angle from being exceeded.

On the other hand, when the pedestal 3 rotates, a space is created between the base 1 and the pedestal 3, and people may enter and exit this space from the inclined approach 2 side.

Since this space cannot be clearly seen from the control panel 71, a safety fence 8 is provided to prevent danger. This safety fence 8 is constructed to be erected in conjunction with the rotation of the pedestal 3.

Next, referring to FIG. 5, concrete pouring work using the present concrete pouring vehicle body tilting device will be explained.

First, as explained above, the car plates 35, 35 of the pedestal 3 are
The roadways 21 and 21 of the inclined approach 2 are configured to be on the same plane, and the mixer truck 100 is made to enter onto the frame 3 from the inclined approach 2. Then, with the rear wheels of the mixer truck 100 in contact with the car stops 34, 34, the stop plates 6, 6 are erected, and the rear wheels are stably temporarily secured on the frame 3.

Further, the front end of the mixer truck 100 can be connected to the pedestal 3 by a chain or the like to prevent the mixer truck from floating.

Next, the hydraulic cylinders 4, 4 are braked and the pedestal 3 is rotated to have an appropriate inclination angle. Due to the inclination of the pedestal 3, the mixer truck 100 has a certain inclination, and the mixer itself also inclines.

As a result, the low slump concrete descends along this slope and is easily discharged from the mixer.

On the other hand, on the rear end side of this tilting device, for example, a bucket 101 is placed on a turntable 102,
Low slump concrete from mixer truck 100 is discharged into this bucket 101. Then, the bucket 101 is lifted by the crane 103 and placed at a pouring site 104, where the bottom of the bucket 101 is opened and low slump concrete is poured.

At this time, an appropriate number of buckets are placed on the turntable 102, and the mixer truck 100
Low slump concrete discharge from and crane 1
03 can be carried out efficiently by rotating the bucket turntable 102.

Moreover, FIG. 6 shows another example of construction using the present vehicle body tilting device for pouring concrete.

According to this construction method, the mixer truck 100 is temporarily fixed on the pedestal 3 in the same way as described above.
Tilt.

In addition, low slump concrete is dropped from this mixer onto a belt conveyor 107 via a chute 105 and a hopper 106, and is transferred to another belt conveyor 108 in conjunction with the operation of the belt conveyor 107 to be transferred to a pouring site 104 with a low slump. Place concrete.

Since this tilting device has the above configuration, it can be installed freely according to the topography of the site, and since the base is configured flat,
It can be stably placed on the ground and does not require anchoring. Also, since it does not require anchoring, it can be easily moved to other sites.

Furthermore, the inclination angle of the pedestal can be arbitrarily set depending on the situation at each site and the degree of low slump.

In this way, by using the vehicle body tilting device for concrete pouring of the present invention, low slump concrete can be discharged completely and in a short time even with a conventional mixer truck, improving concrete quality and pouring performance. It is possible to improve the overall construction efficiency without reducing the construction efficiency.
