[0009] A vibration device according to an embodiment of the present invention will be described below with reference to the drawings. The vibration device is a device that applies vibration to an object placed on mortar. In the embodiment described below, the object will be described as a concrete block (hereinafter, referred to as a block), but it may be any object that is placed on mortar, such as a fixed-shaped block such as a refractory block, or a stone to be placed in a rock garden.

[0010] (Embodiment 1) The vibration device of the embodiment 1 will be described below. Fig. 1 is a diagram showing a state of use of the vibration device 10. The vibration device 10 is a device in which mortar 101 is applied to an installation surface 100 on which a block 102 is to be installed, and the vibration device 10 drops the block 102 into the mortar 101 by vibrating the mortar 101 through the block 102 placed on the mortar 101.

[0011] The block 102 has a rectangular parallelepiped shape, and an opening 103 that opens upward is formed on the top surface of the block 102. The shape of the block 102 and the number of the openings 103 are not particularly limited. The vibration device 10 applies vibration to the block 102 by inserting a hanger pin 1 (described later) into one of the three openings 103 and vibrating in that state. FIG. 1(A) shows the state before the hanger pin 1 is inserted into the opening 103, and FIG. 1(B) shows the state after the hanger pin 1 is inserted into the opening 103.

[0012] Fig. 2 is a front view of the vibration device 10. Fig. 3 is a top view of the vibration device 10. Fig. 4 is a side view of the vibration device 10.

[0013] The vibration device 10 includes a hanging pin 1 , a hydraulic drive unit 2 , and a vibration motor 3 .

[0014] The hanger pin 1 is a cylindrical member that is expandable and contractable in the radial direction, and is a holding part that holds the block 102. The hanger pin 1 is configured to be insertable into the opening 103 of the block 102, expand in the radial direction when inserted into the opening 103, and be able to come into close contact with the wall surface of the opening 103, and holds the block 102 from the inside of the opening 103.

[0015] 5 and 6 are diagrams for explaining the configuration of the hanger pin 1. Fig. 5 is a cross-sectional view of the hanger pin 1. Fig. 6 is a diagram of the cylindrical hanger pin 1 viewed from the axial direction. Note that, in the vibration device 10, the axial direction coincides with the vertical direction when in use. Therefore, in the following description, the axial direction will be taken as the vertical direction.

[0016] The hanging pin 1 has a shaft portion 11, a peripheral wall portion 12 arranged in the circumferential direction of the shaft portion 11, and a connection portion 13 that connects the shaft portion 11 and the peripheral wall portion 12.

[0017] The shaft portion 11 has a cylindrical shape that is long in the vertical direction. The shaft portion 11 is supported by the shaft support portion 11A so as to be movable in the vertical direction, and one end of the shaft portion 11 is connected to the hydraulic drive portion 2. The shaft portion 11 moves along the vertical direction when driven by the hydraulic drive portion 2. Hereinafter, moving the shaft portion 11 in a direction in which the other end of the shaft portion 11 approaches the shaft support portion 11A will be referred to as "pulling up the shaft portion 11," and moving the shaft portion 11 in a direction in which the other end of the shaft portion 11 moves away from the shaft support portion 11A will be referred to as "pulling down the shaft portion 11."

[0018] The peripheral wall portion 12 has a plurality of (four in FIG. 6) arc-shaped members, each of which is arranged along the circumferential direction of the shaft portion 11 so as to surround the outer periphery of the shaft portion 11. Each member is connected to the shaft portion 11 by a connection portion 13. The peripheral wall portion 12 is held by a shaft support portion 11A so as to be movable in a radial direction perpendicular to the vertical direction, but not to be movable in the vertical direction.

[0019] The connection portion 13 that connects the shaft portion 11 and the peripheral wall portion 12 is provided so as to be rotatable about the connection portion with the peripheral wall portion 12 and the connection portion with the shaft portion 11 as fulcrums. The connection portion 13 connects the shaft portion 11 and the peripheral wall portion 12 in a state inclined with respect to the vertical direction.

[0020] With the hanging pin 1 configured as described above, the peripheral wall portion 12 moves in the radial direction as the shaft portion 11 is pulled up and down. In detail, when the shaft portion 11 is pulled up from the state shown in FIG. 5(A), the connection portion 13 pushes the peripheral wall portion 12 radially outward, as shown in FIG. 5(B), and the inclination angle increases. As a result, the peripheral wall portion 12 expands in the radial direction. On the other hand, when the shaft portion 11 is pulled down from the state shown in FIG. 5(B), the connection portion 13 pulls the peripheral wall portion 12 radially inward, as shown in FIG. 5(A), and the inclination angle decreases. As a result, the peripheral wall portion 12 shrinks in the radial direction.

[0021] 5(B), when the peripheral wall portion 12 is in close contact with the wall surface of the opening 103, a gap is formed between the hanging pin 1 and the mortar 101. This prevents the mortar 101 from being directly vibrated by the vibration device 10, making it easier to adjust the thickness of the mortar 101. The reason for this is that when the mortar 101 is directly vibrated, the fluidity of the mortar increases compared to when the mortar 101 is not directly vibrated, making it difficult to control the thickness.

[0022] The configuration of the hanging pin 1 that expands and contracts in the radial direction is not limited to the above, and any known configuration can be appropriately adopted.

[0023] The hydraulic drive unit 2 supports one end of the shaft portion 11 and moves the shaft portion 11 in the vertical direction by hydraulic pressure. The hydraulic drive unit 2 can be a well-known configuration such as a hydraulic jack, and therefore a description thereof will be omitted. The hydraulic drive unit 2 is provided with a hydraulic pump connection portion 4. A hydraulic pump (not shown), which serves as a power source, is connected to the hydraulic pump connection portion 4.

[0024] Incidentally, the means for moving the shaft portion 11 of the hanging pin 1 is hydraulic, but may be electric or mechanical.

[0025] The vibration motor 3 is a vibration unit that is fixed to the hydraulic drive unit 2 and vibrates the hanging pin 1 and the hydraulic drive unit 2. The vibration motor 3 is not particularly limited as long as it is a motor such as an eccentric motor that can vibrate the hanging pin 1 and the hydraulic drive unit 2 and generates vibrations that are transmitted from the hanging pin 1 to the block 102. The vibration motor 3 is fixed to the hydraulic drive unit 2 with its rotation axis 3A aligned with the vertical direction.

[0026] A method of using the vibration device 10 configured as described above will be described below. Mortar 101 is applied to the installation surface 100, and a block 102 is placed on the mortar 101. The hanging pin 1 of the vibration device 10 is inserted into the opening 103 of the block 102 in a radially contracted state. The hydraulic drive unit 2 is driven to pull up the shaft 11, thereby expanding the peripheral wall 12 in the radial direction. As a result, the peripheral wall 12 presses against the wall surface of the opening 103 and comes into close contact with it. As a result, the vibration device 10 holds the block 102.

[0027] With the block 102 held, the vibration motor 3 is driven to vibrate the entire vibration device 10. The rotation axis 3A of the vibration motor 3 coincides with the vertical direction. In other words, when the vibration device 10 holds the block 102, the rotation axis 3A of the vibration motor 3 coincides with the vertical direction. In this state, when the hanging pin 1 holding the block 102 is vibrated, the vibration in the horizontal direction, which is the radial and circumferential directions of the rotation axis, becomes stronger. As a result, the block 102 vibrates more greatly in the horizontal direction compared to when the vibration motor 3 is vibrated with the rotation axis 3A aligned with the horizontal direction. The frequency or amplitude of the vibration at this time may be determined based on the size of the block 102, etc.

[0028] When the block 102 vibrates, the mortar 101 vibrates, and the block 102 sinks into the mortar 101. In this manner, the block 102 can be sunk into the mortar 101 without the need for heavy work such as hitting the block 102 to make the block 102 sink into the mortar 101, and without damaging the block 102 by hitting it.

[0029] (Embodiment 2) The vibration device of the second embodiment will be described below. The vibration device of the second embodiment is a device that drops into mortar blocks that are too large to be vibrated entirely by the vibration device 10 of the first embodiment. The vibration device of the second embodiment differs from the first embodiment in the configuration of the holding part that holds the blocks.

[0030] Fig. 7 is a plan view of the vibration device 20. Fig. 8 is a side view of the vibration device 20. Fig. 9 is a front view of the vibration device 20.

[0031] Block 105 has a rectangular parallelepiped shape extending in one direction (hereinafter referred to as the length direction). Vibration device 20 is placed on the upper surface of block 105 and vibrates block 105. Fig. 7 is a view of the upper surface of block 105 seen from the height direction of block 105. Fig. 8 is a view seen from a direction perpendicular to the length direction. Fig. 9 is a view seen from the length direction.

[0032] The vibration device 20 includes a holder 21 and a vibration motor 3 .

[0033] The holding portion 21 holds the block 105 by sandwiching the sides of the block 105. The holding portion 21 includes a base 22, a handle 23, and a fixing portion 24. Note that the fixing portion 24 is not shown in Figs. 7 and 9.

[0034] The base 22 is placed on the upper surface of the block 105. The base 22 extends in the length direction, and at least one end is bent into an L shape. The L-shaped bent portion of the base 22 supports the side surface of the block 105. A fixing portion 24 is provided on the other end of the base 22.

[0035] Fixing part 24 has shaft part 24A that supports the side surface of block 105, and lever 24B. Fixing part 24 is configured such that shaft part 24A advances and retreats in the length direction by operating lever 24B, as shown by the arrow in Fig. 8. Fixing part 24 holds block 105 from both side surfaces by the L-shaped bent part and shaft part 24A as shaft part 24A moves toward block 105.

[0036] The handle 23 is provided on the base 22 and is grasped by an operator when attaching or detaching the base 22.

[0037] The vibration motor 3 is fixed to the base 22. The vibration motor 3 is the same as in the first embodiment, and therefore a description of the configuration thereof will be omitted. The vibration motor 3 is fixed to the base 22 so that its rotation axis 3A is perpendicular to the plane of the base 22. In other words, the vibration motor 3 is oriented such that its rotation axis 3A coincides with the vertical direction. This allows the block 105 to vibrate more greatly in the horizontal direction, as in the first embodiment.

[0038] The vibration device 20 configured as described above vibrates the vibration motor 3 while holding the block 105 with the holding part 21, so that the vibration of the vibration motor 3 is transmitted from the block 105 to the mortar via the holding part 21. As the block 105 and mortar vibrate, the block 105 sinks into the mortar. In this way, the block 105 can be sunk into the mortar without the need for heavy work such as hitting the block 105 to make it sink into the mortar, and without damaging the block 105 by hitting it.
