Description

The present invention relates to a residual concrete recovery vehicle, and more particularly, to a vehicle capable of recovering residual concrete generated at a construction site.

In general, when concrete is placed at a construction site, a supply device is required to supply concrete, and a separate transfer device is used to transfer the concrete supplied from the supply device to a location where concrete is to be placed.

At this time, a ready-mixed concrete car is used as the supply device, and a concrete pump car with a pump capable of pouring the ready-mixed concrete supplied from the ready-mixed concrete car is used as the transfer device.

In general, the concrete in the concrete pump vehicle is discharged as it is after the completion of concrete placing.

When the residual concrete is discharged to the construction site in this way, environmental pollution and other construction progress impediments occur.

Therefore, collection vehicles capable of collecting waste concrete by various methods have been developed.

For example, there is a concrete rotating chute car disclosed in Korean Patent No. 10-2300120.

However, since the concrete rotary chute car is used with a collection part separately provided on the rear surface of the ready-mixed concrete car, it is easy to use at a large construction site where the ready-mixed concrete car, which is a large vehicle, can work, but it has the disadvantage that it is difficult to use at a narrow construction site.

For the above reasons, the field has attempted to develop a device capable of recovering residual concrete generated after concrete placement, but until now, satisfactory results have not been obtained under various site conditions.

Korean Patent No. 10-2300120

The present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the residual concrete recovery vehicle 1 according to the present invention includes a recovery section 100, a loading section 200, a recovery operation section 300, and a control section 500. As shown in FIG.

The recovery unit 100 of the present invention can include a recovery box 110 in which the residual concrete 10 is stored in the recovery space, as shown in FIG.

At this time, the collection box 110 may be arranged to cover the upper end of the loading unit 200 .

Here, the collection box 110 may be provided with a discharge port 120 through which the residual concrete 10 can be discharged.

At this time, the outlet 120 may comprise a plate (not shown) as an example.

Here, the plate (not shown) may be configured in various ways, such as a structure that is coupled with a speed reducer or a structure that rotates with a plurality of gears, and any structure and method that can open or close the discharge port 120 may be used, so a detailed description of the structure that can be opened or closed will be omitted.

More specifically, the collection bin 110 is divided into a first zone 130 and a second zone 140 .

Here, the first zone 130 has a plurality of inclined surfaces 135 through which the residual concrete 10 can be easily discharged.

At this time, the inclined surfaces 135 are provided on the bottom and both sides of the collection box 110 as an example, the inclined surfaces 135 on both sides gather the residual concrete 10 toward the discharge port 120, and the inclined surfaces 135 on the bottom are inclined within a predetermined angle toward the discharge port 120, so that the collected residual concrete 10 can be discharged more smoothly.

Here, the second section 140 is provided with a collection box cover 145 to prevent the hopper 30 from detaching from the collection box 110 due to vibration or impact when receiving the residual concrete 10 .

At this time, a support member 160 may be provided to support the collection box 110 from the ground.

Here, the support member 160 may be provided on the bottom surface of the collection box 110 as an example.

The support members 160 may also be wheels, as shown in FIG. 4, or, alternatively, cylindrical rollers (not shown).

At this time, the position of the support member 160 may be a position where the collection box 110 can be coupled to the upper end of the loading unit 200, so various embodiments can be applied according to the design.

The load station 200 of the present invention may comprise a load frame 205 mounted on the vehicle 50, as shown in FIG.

At this time, the loading frame 205 may be provided with a loading box 210 on which the residual concrete 10 can be loaded.

Here, the rear surface of the loading box 210 may be provided with a tailgate 220 through which the loaded residual concrete 10 can be discharged.

At this time, the tailgate 220 opens and closes the rear surface of the loading box 210 to discharge the loaded residual concrete 10 and prevent the residual concrete 10 from leaking during loading.

Moreover, as shown in FIG. 4, the loading box 210 may be provided with a gasket 215 for preventing leakage of the residual concrete 10 on the surface with which the recovery unit 100 abuts.

At this time, when the collecting part 100 is positioned and covered on the upper end of the loading box 210, the collecting part 100 abuts against the gasket 215 to prevent the residual concrete 10 from leaking.

Here, one surface of the loading frame 205 is provided with lift cylinders 230 that can be extended or contracted to vertically move the front side of the loading frame 205, and by tilting the loading frame 205 within a predetermined angle, the loaded residual concrete 10 can be smoothly discharged.

At this time, the lift cylinder 230 can be controlled by the controller 500, which will be described later.

Here, as an example, when the lift cylinder 230 is fully extended, the tailgate 220 is opened and closed, so that the residual concrete 10 loaded on the loading box 210 can be discharged more smoothly.

As shown in FIG. 4, the retrieving operation unit 300 of the present invention may include folding cylinders 310 that are provided on both sides of the loading unit 200 and extend or contract to adjust the distance between the loading unit 200 and the retrieving unit 100.

At this time, the loading frame 205 provided with the folding cylinder 310 cannot protrude beyond the width of the vehicle 50 according to relevant regulations, so it can be deformed into various shapes according to the design so that the folding cylinder 310 does not protrude.

At this time, one side of the folding cylinder 310 may be provided with an auxiliary cylinder 320 that expands or contracts.

Here, the auxiliary cylinder 320 has one end coupled to the folding cylinder 310 and the other end coupled to the loading frame 205 to support the folding cylinder 310 when the folding cylinder 310 is extended.

At this time, the folding cylinders 310 and the auxiliary cylinders 320 are preferably driven by hydraulic cylinders, but this is not limited to hydraulic cylinders, and the folding cylinders 310 and the auxiliary cylinders 320 can be operated using other means such as a motor as power means.

Here, the collection box 110 may be provided with a rotating support member 330 that is connected to one end of the folding cylinder 310 and rotatable.

At this time, the rotation support member 330 is provided to traverse the inside of the collection box 110, and rotates when the collection box 110 is extended and moved by the folding cylinder 310, so that the horizontality of the collection box 110 can be kept constant.

The detection unit 400 of the present invention is provided in the collection unit 100 and can detect the horizontal and rotation angles of the collection unit 100 .

At this time, as an example, the detection unit 400 may include a gyro sensor 405 capable of detecting the horizontal state and rotation angle of the recovery unit 100, as shown in FIG. 5(a).

As another example, as shown in FIG. 5B, a horizontal sensor 410 for detecting the horizontality of the collecting unit 100 may be provided, and an encoder sensor 420 for detecting the rotation angle of the collecting operation unit 300 may be provided.

The control unit 500 of the present invention can control the operation of the collection operation unit 300 based on the horizontal and rotation angles detected by the detection unit 400 .

Here, when controlling the recovery operation unit 300, as an example, the rotation angles of the folding cylinder 310 and the rotation support member 330 are adjusted based on the horizontal and rotation angle values detected by the detection unit 400, so that the residual concrete 10 stored in the recovery box 110 can be poured onto the loading unit 200.

As another example, the collecting unit 100 and the collecting operation unit 300 can be manually operated by an operator via the control unit 500 .

At this time, an infrared sensor (not shown) that emits infrared rays outward in parallel with the ground is provided at the upper end of the recovery unit 100 for safety during manual operation, and a configuration that emits an alarm sound depending on the presence or absence of an object to be detected may be added.

Here, the configuration for setting the height by a separate position measurement sensor and emitting an alarm sound according to the presence or absence of a plurality of detected objects may be of any ordinary structure and method, but detailed description thereof will be omitted.

Next, the case of working with the residual concrete recovery vehicle 1 according to the present invention will be described.

As shown in FIG. 1, the residual concrete recovery vehicle 1 according to the present invention includes a recovery unit 100, a loading unit 200 that receives and loads the residual concrete 10, and a recovery operation unit 300 that is provided between the loading unit 200 and the recovery unit 100 and enables positional movement and angle adjustment of the recovery unit 100.

Here, the recovery operation unit 300 can be controlled by the control unit 500 based on the horizontal and rotation angles detected by the detection unit 400 that detects the horizontal and rotation angles of the recovery unit 100 .

At this time, when the device is operated for collecting the residual concrete 10, the folding cylinder 310 allows the collecting box 110 to move on top of the loading box 210, as shown in FIG.

Here, the rotation support member 330 allows the collection box 100 to be kept horizontal and positioned near the ground.

At this time, as shown in FIG. 6, when the folding cylinder 310 is fully extended, the auxiliary cylinder 320 supports the extended folding cylinder 310, and the collection box 110 can receive the residual concrete 10 transferred via the pump car 20 to the collection box 110 via the hopper 30.

Here, the collection box cover 145 can prevent the separation of the hopper 30 used when receiving the transfer of the residual concrete 10 .

At this time, when a certain amount of residual concrete 10 is collected in the recovery box 110, the folding cylinder 310 is contracted to position the recovery box 110 at the upper end of the loading box 210, as shown in FIG.

Here, when the residual concrete 10 is collected in the loading box 210, as shown in FIG. 1, the collection box 110 is arranged to cover the loading box 210 and block the outflow of the residual concrete 10 to the outside.

The invention described above is not limited to the above embodiments, and can be modified within the scope of the invention claimed in the claims, and such modifications are also within the scope of protection of the invention defined by the description of the claims.
