Description

A portable concrete placement device for narrow slot

Technical Field

The utility model relates to a concrete pouring auxiliary device, in particular to a movable concrete pouring device for a narrow groove.

Background

Municipal sewage is often transported through sewage pipes. The sewage pipe network has large engineering quantity and wide range, the pipe network is mainly laid in a roadway, after the pipeline is laid with grooves for backfilling, the pavement of the grooves needs to be concreted, and a concrete transportation tank is usually required to be concreted in situ. Because the concrete transportation tank truck cannot directly reach due to the limitation of site conditions, workers are required to move the concrete on the concrete transportation tank to the road surface of the designated narrow groove on site, and casting operation is carried out on the narrow groove. The patent with the application number of 202221697630.5 is a movable narrow-groove pavement concrete pouring device, a traction device is adopted to traction a hopper carrier vehicle to move, and a hopper body on the hopper carrier vehicle pours concrete into a narrow groove. The lower end of the hopper body of the device is far away from the narrow groove, and concrete is easy to splash everywhere.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a movable concrete pouring device for a narrow groove, which can reduce the distance between a discharge hole and the ground and ensure that concrete accurately falls into the narrow groove.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the movable concrete pouring device for the narrow groove comprises rails arranged on two sides of the narrow groove, a hopper is arranged on the rails in a sliding mode, a material guiding opening is formed in the lower end of the hopper, an opening and closing door is arranged at the bottom of the material guiding opening, and the opening and closing door is driven to be opened or closed through a first cylinder; the lower end of the material guiding opening is opposite to the narrow groove; an extension tube is arranged in the material guiding opening, an upper limit ring is arranged at the upper end of the extension tube, and a lower limit ring is arranged at the bottom end of the material guiding opening; the upper limit ring is limited by the lower limit ring when moving to the lower limit position.

And a vibrating motor is arranged at the lower part of the hopper.

The utility model discloses a movable concrete pouring device for a narrow groove, which has the following technical effects:

1) The hopper is arranged on the rails on two sides of the narrow groove in a sliding mode, the hopper can be directly pushed while being discharged, linear motion can be achieved, pouring is achieved, and the operation is simpler and more reliable compared with traction equipment.

2) The opening and closing door and the first cylinder are arranged at the material guiding opening, so that the opening and closing can be performed at any time; when pouring of one narrow groove is completed and the rest of concrete in the hopper is left, the material guiding opening can be closed, and the next position is transferred to perform pouring, so that the flexibility is improved.

3) By sleeving the extension pipe in the material guiding opening, the extension pipe is basically and quickly close to the ground after extending out, so that concrete can directly and accurately fall into the narrow groove to avoid splashing.

Detailed Description

As shown in fig. 1 to 3, a movable concrete pouring device for narrow grooves comprises a hopper 2, wherein supports are welded at the left and right of the lower end of the hopper 2, rollers are arranged in front of and behind the supports, and the rollers are arranged on a track 1 paved on the ground in a sliding manner. The narrow groove to be poured is formed between the two rails 1. The bottom of the hopper 2 is provided with a material guiding opening 3 matched with the width of the narrow groove, and the bottom of the material guiding opening 3 is provided with an opening and closing door 4. The opening and closing door 4 comprises a left fan-shaped connecting plate and a right fan-shaped connecting plate, and the upper ends of the two fan-shaped connecting plates are hinged on the outer side wall of the hopper 2. The bottoms of the two fan-shaped connecting plates are connected with arc plates, and the arc plates can seal the material guiding opening 3. An ear plate is welded on one side of the arc plate and hinged with the first air cylinder 5, the other end of the first air cylinder 5 is hinged on a connecting plate, and the connecting plate is fixed on the outer side of the hopper 2.

When pouring is required, the hopper 2 is moved forwards along the track 1, the first cylinder 5 is started, the first cylinder 5 is contracted, the opening and closing door 4 is opened, and concrete falls into the narrow groove from the material guiding opening 3 to perform pouring operation.

As shown in fig. 2, a vibration motor 6 is mounted at the lower part of the hopper 2. The vibrating motor 6 is connected with an external power supply, and can vibrate during pouring, so that quick discharging is facilitated.

As shown in fig. 4-6, an extension tube 7 is arranged in the material guiding opening 3, an upper limit ring 8 is arranged at the upper end of the extension tube 7, and a lower limit ring 9 is arranged at the bottom end of the material guiding opening 3; the upper limit ring 8 is limited by the lower limit ring 9 when moving to the lower limit position. When the material guiding opening 3 is closed, the extension pipe 7 is retracted into the material guiding opening 3, and the upper side of the upper limiting ring 8 is in smooth transition with the inclined plane of the inner surface of the hopper 2. When the material guiding opening 3 is opened, the extension pipe 7 can extend out of the material guiding opening 3 under the action of gravity, the extension pipe 7 can extend the length of the whole blanking pipe, the upper port of the narrow groove can be accessed, concrete can be conveniently and accurately introduced and poured, and splashing is avoided.
