Definitions

  • the drive of the tank being produced by friction on belts, the size of the tank can be adapted so that it can be transported with its tank support in a van, for example.
  • the capacity of the tank preferably varies between 0.5 m 3 and 1.5 m 3 .
  • the two sets of drive are interconnected via a first and a second drive shaft, so that the two belts drive the tank at the same speed.
  • the two belts are driven simultaneously and it is therefore necessary, during their mounting and possibly in use, especially during the wear of one of the belts, to synchronize them.
  • two belts are tensioned using tensioning means. We first tension the belt of the first set, then to the tension of the belt of the second set.
  • the synchronization means include advantageously, a variable clamping hub for mounting a roller of one of the two drive assemblies on said second drive shaft. So the last pebble of the second drive assembly can be free to rotate, when second belt tension.
  • the tensioning means advantageously comprise two tensioners which allow the belt to be tensioned during assembly or during possible loosening of the belt during time.
  • the drive means of at least one drive assembly includes a motor.

  • Guide rails 40 and 42 can be attached to the floor of the van 10 near the side members of the chassis, so as to facilitate sliding guidance of the device 12 in the van 10.
  • Figure 5 shows a first set of training 44A and a second drive assembly 44B for the support and the rotation of the tank 14.
  • the first drive assembly 44A includes a belt 46A intended to support and drive the tank 14 in rotation around the XX 'axis.
  • Belt 46A is mounted around two rollers 48A and 50A. To increase the force transmission between the belt 46A and the two rollers 48A and 50A, these can be notched, just like the 46A belt.
  • the first drive assembly 44A is connected to the second drive assembly 44B by two shafts transmission 52, 54.
  • the transmission shaft 52 is connected to the rollers 48A and 48B, while the transmission shaft 54 is connected to the rollers 50A and 50B.
  • the device 12 includes means for synchronization.
  • the rollers 48A and 50A of the first set 44A drive are fixed, by tight fitting or by keying for example, on their respective transmission shaft 52 and 54.
  • roller 48B of the second set 44B drive is also fixed on its transmission shaft 52.
  • the other roller 50B of the second drive assembly 44B is free in translation and in rotation on the drive shaft 54.
  • the means of synchronization include a hub 56 with variable clamping, disposed between the drive shaft 54 and the roller 50B, which allows mounting the roller 50B.
  • the hub 56 is composed of a set of two coaxial conical rings 56A and 56B, split longitudinally, the inside diameter of which varies when tightened a clamping screw 56C by varying the opening or closing from their respective slots.
  • the two conical rings 56A and 56B are placed between the roller 50B and the drive shaft 54.
  • Each of the rings 56A, respectively 56B has a conical crown 56'A, respectively 56'B, intended to slide on a corresponding conical portion of the roller 50B. So the conical crown 56'A is capable of sliding against the conical portion 51'B and the conical crown 56'B is capable of sliding against the tapered portion 51 "B.
  • the taperings of the two rings 56A and 56B and roller 50B, are such that when tightening the clamping screw 56C, the rings 56A and 56B approach each other causing the closure of their respective slots 56 "A and 56" B and therefore the locking of the roller 50B on the transmission shaft 54.
  • the assembly of the device 12 begins with the installation teeth 46'A of the belt 46A on the teeth 48'A of a first roller of the first drive assembly 44A, for example the roller 48A, as shown in Figure 7A. Then the teeth 46'A of the belt 46A are placed on teeth 50'A of the second roller 50A of the first drive assembly 44A.
  • the first set drive 44A includes tensioning means 58A which allow the belt 46A to be tensioned on the two rollers 48A and 50A.
  • the tensioning means 58A comprise a set of two rollers tensioners 60A and 62A tightened by two respective bolts 64A and 66A. The tightening of these two bolts 64A and 66A causes tension more or less important of the belt 46A. Gradually as the tension of the belt 46A increases, the roller 50A rotates in the clockwise, while the roller 48A is immobilized by immobilizing the transmission shaft 52 on which it is mounted integrally.
  • the mounting of the belt 46B of the second set 44B drive is done with the same elements, as shown in Figure 7B.
  • the belt tension 46B, roller 50B rotates in the opposite direction clockwise, while the roller 48B is immobilized by immobilization of the transmission shaft 52 on which it is fixed.
  • the transmission shaft 54 is also fixed, since it is linked to the rotation of the transmission shaft 52 via the belt 46A.
  • the hub 56 is not yet tightened, there is a relative sliding between the roller 50B and the drive shaft 54. As soon as the belt 46B is tensioned, the hub 56 is tightened using of the tightening screw 56C and the two belts 46A and 46B are synchronous.
  • the tension of the two belts 46A and 46B is adjusted so that the tank 14 rests on the belts 46A and 46B, in the vicinity of the rollers 48A, 50A, 48B and 50B, the tank 14 therefore being driven by belts 46A and 46B.
  • the tank 14 is thus rotated by friction between the tank 14 and four belt portions 46 48 A, 46 50 A, 46 48 B and 46 50 B, respectively in the vicinity of each roller 48A, 50A, 48B and 50B, when the belts 46A and 46B are rotated.
  • the tank 14 To facilitate the production of the tank 14, it is preferable to provide the tank 14 with two rings 70 and 72 (shown in Figure 8) whose roughness is adjusted. These two crowns 70 and 72 come to bear against these belt portions 46 48 A, 46 50 A, 46 48 B and 46 50 B, the length of which varies, in particular, according to the irregularities of the two crowns 70 and 72 and the weight of the tank 14.
  • the device 12 works well whatever that is the distribution of the load in the tank 14 and whatever its filling level; the tank 14 being itself heavy enough for there to be training without slipping the tank 14 on the belts 46A and 46B.
  • a DC motor 53 (shown in Figure 5) powered by batteries (not shown) drives the shaft of transmission 52 in rotation, which also causes rotation the transmission shaft 54 via the belts 46A and 46B and therefore rotates the tank 14.
  • the motor 53 is of variable speed, so that it can cause the tank 14 to rotate more or less rapidly depending on the needs. Furthermore, the motor 53 has two directions of rotation which allow, as the case may be, the filling of the tank 14, or its discharge, as will be explained below.
  • the batteries supplying the motor 53 can be arranged in a location provided for this purpose on the support tank 16, so that it can be moved with it. This way power supply with batteries gives device 12 the advantage to be both self-sufficient in food and non-polluting.
  • Two helical spirals 14A and 14B are arranged on the inner wall 14C of the tank 14 for allow the filling of concrete 22 towards the bottom of the tank or at otherwise its extraction from the tank 14 depending on the direction of rotation of the tank 14.
  • the two spirals 14A and 14B are formed respectively by a continuous propeller 14A and 14B; both propellers 14A and 14B having the same pitch and rotating in the Same direction.
  • the direction of rotation of the tank 14 determines the operation of the tank 14 in loading or unloading mode. So it is enough the user operating the motor in a direction of rotation or in the other to choose the direction of rotation of the tank 14.
  • the bottom 14D of the tank 14 can advantageously be detachable so as to facilitate cleaning of the spirals 14A and 14B.
  • the axial forces of the tank 14 on the belts 46A and 46B can be taken up by carefully placed rollers.
  • a roller 68 is in contact with a 70 of the crowns 70 and 72 which are formed on the tank 14 and which then come into contact with the belts 46A and 46B (not shown in Figure 8).
  • the axis of rotation XX 'of the tank 14 can be partially superimposed with a material axis, for example a rod (not shown) which would be arranged coaxially with the tank 14 while being fixed to the bottom of the tank 14D and extending outside and the back of the tank 14.
  • This rod can be connected to a anti-skid retainer of the tank 14 on the belts 46A and 46B.
  • the rod is fixed to the tank 14, it is movable in rotation by relative to the retainer itself fixed to the tank support 16 and vice versa.
  • retaining devices for the tank 14 different, can be provided in order to secure the device according to the invention retaining the tank 14, in case it is no longer supported by belts 46A and 46B of the first 44A and second 44B drive sets.
