Detailed Description
the utility model provides a concrete jolter, as shown in fig. 1 and fig. 2, includes the jolter body 1, and the jolter body 1 includes vibration table surface 11, installs tamping unit 3 above vibration table surface 11, and tamping unit 3 supports through the extension board 2 that sets firmly in 1 both sides of jolter body, and one side and one of them extension board 2 of tamping unit 3 are articulated, and the opposite side can be dismantled with another one extension board and be connected. Rotate during the use and open tamping unit 3, place concrete mould 4 containing the concrete on vibration mesa 11, then rotate the closure tamping unit 3, the vibrations of jolt ramming mass body 1 work drive vibration mesa 11, and the concrete in concrete mould 4 shakes the compaction, and tamping unit 3 carries out the tamping to the concrete in concrete mould 4 simultaneously for position composition is even about the concrete in the concrete mould.
Referring to fig. 1 and 2, in order to prevent the concrete form 4 from sliding on the vibration table 11 and affecting the tamping effect, a bar-shaped hole 111 is formed in the vibration table 11, two ends of the bar-shaped hole 111 are respectively provided with a limiting member, the limiting member can be a limiting bolt 12 penetrating through the bar-shaped hole 111, and the limiting bolt 12 is in threaded connection with a nut. The nuts are unscrewed, the limiting bolts 12 can be moved to the two sides of the concrete mold 4 along the strip-shaped holes 111 and tightly attached, and then the nuts are screwed, so that the concrete mold 4 is fixed by the limiting bolts 12.
Referring to fig. 1 and 2, the brace 2 may be fixed with the bench body 1 by a strut 21.
The tamping assembly 3 comprises a base plate 33, a plurality of tamping rods 34 which are fixed on the base plate 33 and distributed in an array, and a cylinder 32 which drives the base plate 33 to move close to or far away from the vibration table 11; the cylinder 32 is connected with the support plate 2 through the mounting plate 31, the cylinder 32 and the mounting plate 31 can be fixed through bolts, and a piston rod of the cylinder 32 penetrates through the mounting plate 31 and is fixed with the base plate 33; the mounting plate 31 is provided with at least one guide hole 311, and the base plate 33 is fixed with a guide rod 35 which passes through the guide hole 311 and slides relatively.
One side of the mounting plate 31 is hinged with one support plate 2 through a hinge, a clamping block 312 is arranged on the other side of the mounting plate 31, and a limiting hole 313 is formed in the clamping block 312. A pair of ear plates 22 is arranged at the end of the other support plate 2 far away from the vibration table 11 corresponding to the position of the fixture block 312, and when the mounting plate 31 rotates to be parallel to the vibration table 11, the fixture block 312 can be clamped between the two ear plates 22. The latch 312 and the ear plate 22 can be fixed by a pin inserted through the limiting hole 313. The end of the bolt can be connected with a nut in a threaded manner, or a spring is connected between the bolt and the lug plate 22 and applies force to the bolt to move towards the limiting hole 313, so that the bolt is prevented from falling from the limiting hole 313 to separate the mounting plate 31 from the support plate 2 in the vibration compaction process.
Referring to fig. 3, the tamper bar 34 can be inserted into the concrete form 4 to a depth of 10-20 cm. In order to prevent the tamper 34 from interfering with the concrete form 4 when the mounting plate 31 is rotated, the distance between the tamper 34 on the side of the base plate 33 remote from the hinged end of the mounting plate 31 and the side wall of the concrete form 4 is greater than the insertion depth of the tamper 34 by 3-5 cm.
