Definitions
- the present invention relates to a concrete pump for the preparation and injection of the concrete thus obtained according to the technique of the present machine.
- the concrete pump consists mainly of a mixing tank for mixing materials, an engine ensuring the operation of a set of mechanical elements and an air compressor and a set of accessories to optimize the maximum operation and performance.
- the concrete pump described is used to prepare concrete concrete at the place of use by mixing and injecting pressurized compressed air using an air compressor. It also makes it possible to reduce all the problems associated with heavy handling, and above all to send the concrete at variable distances horizontally and vertically.
- Figure 1 shows a view of the pump
- FIG. 1 shows the pump frame with its set of mechanisms
- Figure 3 shows the transmission shaft with its reducer
- the concrete pump described essentially consists of a mixing tank (1) mounted on a chassis (21) of a road vehicle equipped with two tires (28) which are resistant and can support all the payloads during long working hours.
- the pump is provided with two stabilizers (32) allowing on the one hand to lift the latter and on the other hand to give it a suitable working height meeting ergonomic standards. This height is manually adjustable.
- the mixing tank (1) is internally fitted with an interchangeable sheet metal lining of curved wear. This protective lining protects the interior of the tank against scraping of the gravel from the concrete during mixing.
- the mixing tank (1) is equipped with a closure cover resistant (46) to the high pressure exerted by the air compressor during concrete transfer operations. This seal is ensured by a rubber seal inserted around the entire circumference of the cover. The location of the seal is protected by two metal hoops used to hold it in place against any possible displacement.
- This closure cover can pivot around an axis during the loading of materials such as sand, cement, gravel. This axis ensuring this opening and closing is fixed by two gussets.
- the lid is closed by means of a lever (31) placed at the rear of the tank, on the top of the rear end of the tank.
- This cover is also equipped with a trap (35) for the mixing tank to evacuate the pressurized air just before it opens, just after the injection of the concrete and before each filling.
- This trap also called a maneuvering valve, is a metal valve ensuring a perfect seal.
- the mixing tank is equipped with a square shaped drive shaft on which four mixing blades are fixed. These blades are slightly inclined towards the inside of the tank. This inclination of about 45 ° allows better scraping of the concrete at the bottom of the tank.
- the transmission shaft with its reducer is equipped with a universal joint (6) assembled between the sleeve (5) of the shaft (3) and the sleeve (7) of the reducer.
- the drive shaft (14) is driven by a reduction unit (10) composed of a drive pinion, a two-stage pinion and a single pinion.
- the reduction unit is equipped at the inlet with a pulley (26) connected to the compressor motor by a belt mounted on another pulley thus ensuring its drive through the axis of the compressor. This mounted pulley also serves to drive the hydraulic pump (25).
- the mixing tank is surmounted by one or two skips (or hopper) (34) ensuring the supply of building materials to the mixing tank. It has the shape of a movable visor and is synchronized with the movements of the machine. It can also be manipulated by the two handles (30) placed at the rear of the concrete pump.
- the skip (s) are equipped with an interchangeable cement bag holder () facilitating handling during loading maneuvers.
- the OR the two skips are lifted during the various loading operations by hydraulic cylinders.
- a hydraulic distributor is placed on its support and fixed by bolts on the rear end of the tank. The hydraulic distributor controls the two skips in all operations.
- the concrete pump is supplied with water through a tank placed at the rear of the machine.
- the water tank is equipped with a flow regulator allowing each filling to pour a quantity previously determined for each dosage.
- the machine or the concrete pump is driven by an electric motor (27) of 10 CV of 1500 revolutions per minute.
- This electric motor is placed on the front of the machine and drives the reduction unit (25) thanks to the pulley (26).
- This transmission is ensured by a belt placed on the one hand on the pulley of the engine and on the other hand on the pulley of the rector.
