In the present invention, as shown in fig. 1-6, there is provided a seismic source generating device, comprising a supporting frame 1, a driving rope 2, a weight 3, and a driving member, wherein the weight 3 comprises a first connecting portion 5 having a hanging hole 4, and the seismic source generating device further comprises: the second connecting part comprises two connecting blocks 6, the upper ends of the two connecting blocks 6 are hinged, at least one inserting rib 7 extending transversely is formed at the lower end of one connecting block 6, when the two connecting blocks 6 are closed, the inserting rib 7 can be inserted into the hanging hole 4, and the driving piece can drive the driving rope 2 to drive the second connecting part to move upwards; the connecting assembly is arranged on the second connecting part and can connect the two connecting blocks 6 to be in a close state; the unlocking piece can release the connection of the connecting assembly and one of the connecting blocks 6, so that the dowel bars 7 can be separated from the hanging holes 4.

The utility model discloses a seismic source generating device is when using, when weight 3 is located ground position department, transfers through drive rope 2, then opens two connecting blocks 6 to insert dowel 7 in hanging hole 4, make two connecting blocks 6 draw close, then connect two connecting blocks 6 through coupling assembling. At this moment, can drive driving rope 2 through the driving piece and lift up weight 3, when mentioning to a take the altitude, relieve the connecting piece through the unblock piece and be connected with one of them connecting block 6, at this moment, the rotation that two connecting blocks 6 can be free, under the effect of weight 3 dead weight, first connecting portion 5 can be by breaking away from the whereabouts between two connecting blocks 6.

The utility model discloses a seismic source generating device has adopted mechanical type connection structure between weight 3 and the driving rope 2, compares in the mode that adopts the electro-magnet sucking disc among the present formula seismic source generating device that falls, because the battery iron is higher to power supply and self state requirement, the utility model discloses a connection structure between weight 3 and the connection rope 8 is connected more stably, has reduced the requirement to on-the-spot power supply, has still reduced because the possibility that weight 3 that the electro-magnet failure leads to drops suddenly.

Even in some embodiments, no electrical component may be used between the weight 3 and the driving rope 2, so that the circuit layout of the seismic source generator can be reduced.

Wherein, it is required to explain that the utility model discloses the improvement part is directed against the connection structure between weight 3 and the driving rope 2, does not do specific restriction to other structures, and other structures can adopt the structure in the current hammer drop hammer hammering source. For example, in the embodiment shown in fig. 1, the support frame 1 is a three-legged support frame 1, and the driving member may be an electric hoist fixed on the top of the support frame 1. Or, a winch can be arranged on one of the supporting legs, a guide pulley is arranged at the top of the supporting frame 1, and the driving rope 2 is connected with the heavy hammer 3 after passing around the guide pulley.

In the embodiment shown in fig. 1, more specifically, the connection assembly includes a connection rope 8 and a plug 9, one end of the connection rope 8 is connected to one of the connection blocks 6, a through hole 10 for the connection rope 8 to pass through is formed in the other connection block 6, a hanging ring 11 is formed at an end of the connection rope 8 passing through the through hole 10, and the plug 9 can be inserted into the hanging ring 11. As shown in fig. 2 and 5, after the two connecting blocks 6 are closed, the hanging ring 11 connected with the connecting rope 8 passes through the through hole 10 and passes through the hanging ring 11 through the bolt 9, at this time, the connecting rope 8 and the bolt 9 can limit the two connecting blocks 6 to be opened, so that the connecting rope 7 can be separated from the hanging hole 4, and the second connecting part and the first connecting part 5 are fixed.

As shown in fig. 3, by using the connection rope 8, after the latch 9 is separated from the hanging ring 11, when the two connection blocks 6 are separated, the connection rope 8 can be quickly removed from the through hole 10. Wherein, the hanging ring 11 can be knotted at the end of the connecting rope 8 to form a ring, or the connecting ring is separately arranged at the end of the connecting rope 8.

Preferably, the connecting block 6 at the position of the bolt 9 is provided with a guide block 12, and the guide block 12 is provided with a guide hole 13 for the bolt 9 to pass through.

The further optimization is that one end of the bolt 9 is provided with a cap head 14, and the guide block 12 is magnetically connected with the cap head 14. As shown in fig. 5, an iron cap 14 may be used, and a magnet may be provided on the lower surface of the guide block 12, thereby preventing the falling of the weight 3 caused by the random downward movement of the pin 9.

To the structure of the unlocking part, in the embodiment shown in fig. 1, further specifically, the axis of the guide hole 13 is vertically arranged, the bolt 9 passes through the guide hole 13 from bottom to top, the unlocking part includes an unlocking block 15 arranged on the support frame 1, and when the driving rope 2 drives the second connecting part to move upwards, the unlocking block 15 can push the bolt 9 to move downwards to separate from the hanging ring 11. As shown in fig. 2 and 5, the cap head 14 extends transversely, and when the driving rope 2 drives the first connecting portion 5 to move upwards to the unlocking block 15, the unlocking block 15 can abut against the outer edge of the cap head 14 to drive the latch 9 to move downwards. From this it is difficult to see, the utility model discloses a generating device can be when weight 3 upwards removes to a certain extent, automatic release weight 3, and it is more convenient to use.

When the bolt 9 is inserted into the hanging ring 11, the connecting rope 8 tensions the bolt 9, so that the bolt 9 is abutted against the connecting block 6 at the corresponding position, and therefore, when the unlocking piece does not perform unlocking action, the bolt 9 is not easy to fall.

More specifically, as shown in fig. 2, the unlocking piece 15 has a ring shape. This ensures that the unlocking piece 15 can abut against the cap head 14.

As shown in fig. 2, the cap head 14 extends laterally to a certain length, and when the unlocking block 15 pushes the cap head 14, the distance between the inner edge of the unlocking block 15 and the outer edge of the connecting block 6 is reserved to leave a space for the connecting block 6 to rotate and open, so as to ensure that the weight 3 can be released.

As shown in FIG. 6, the lower end of the unlocking rope 16 extends downward, and when it is necessary to release the weight 3, the user can pull the unlocking rope 16 manually to pull down the latch 9.

A further refinement provides that the top faces of the ribs 7 extend obliquely downwards in the direction away from the connecting piece 6. As shown in fig. 5, the weight 3 can generate a horizontal component force to the tendon 7 by its own weight after losing the constraint of the connecting rope 8, so as to separate the two connecting blocks 6 quickly and release the weight 3.

In an alternative embodiment, a spring may also be provided between the two connecting pieces 6. So that the spring can push the two connecting blocks 6 to open quickly after the restraint of the connecting rope 8 is lost.

In the embodiment shown in fig. 1, more specifically, the two connecting blocks 6 are respectively provided with the dowels 7, and the dowels 7 of the two connecting blocks 6 are arranged in a staggered manner along the direction of the hinge axis of the two connecting blocks 6.

More specifically, the first connecting portion 5 is a connecting rod integrally formed with the weight 3, and the hanging hole 4 is formed in the connecting rod.
