DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In seismic exploration projects, it is necessary to obtain seismic waveforms under the strata. Usually, a special heavy hammer is used as the exploration source to stimulate vibration and obtain seismic waveforms. Specifically, the heavy hammer is suspended at a certain height and then released to hit the ground to cause vibration. This is used as the exploration source.

[0041] At present, the common method for picking up and releasing the heavy hammer is to hang the heavy hammer by a hook or manually, and then release the heavy hammer by manually pulling the hook. However, this method of picking up and releasing the heavy hammer is inconvenient to operate, and the heavy hammer needs to be manually raised each time after hanging, which consumes a lot of manpower.

[0042] Reference Figure 1 and Figure 2 ,in, Figure 1It is a structural schematic diagram of a clamping member 5 in a heavy hammer release device for seismic exploration proposed in an embodiment of the present application in a clamping state; Figure 2 It is a structural schematic diagram of a clamping member 5 in a released state in a heavy hammer release device for seismic exploration proposed in an embodiment of the present application.

[0043] A weight release device for seismic exploration, the device comprising:

[0044] A column 1, the bottom of which is placed on the ground;

[0045] A fixing frame 2 is fixed to the column 1, and a clamping member 5 is provided at the bottom of the fixing frame 2. The clamping member 5 has a release state and a clamping state. In the clamping state, the clamping member 5 is used to clamp the weight, and in the released state, the clamping member 5 is used to release the weight;

[0046] A movable frame 3 is slidably connected to the column 1;

[0047] A driving assembly, wherein the driving assembly is fixed to the movable frame 3, and a driving end of the driving assembly is connected to the fixed frame 2;

[0048] When the driving end of the driving assembly extends, the movable frame 3 moves upward and contacts the first position 6 of the clamping member 5 to drive the clamping member 5 to a released state; when the driving end of the driving assembly retracts, the movable frame 3 moves downward and contacts the second position 7 of the clamping member 5 to drive the clamping member 5 to a clamping state.

[0049] The column 1 is cylindrical, and is vertically arranged, and the length direction of the column 1 is perpendicular to the ground. The column 1 is arranged to provide a connection position for the connection of the fixed frame 2, and to provide a guide for the movement of the movable frame 3.

[0050] Specifically, the fixing frame 2 is fixed to the column 1, and the fixing frame 2 is connected to a position slightly below the midpoint of the length of the column 1. Since the fixing frame 2 is provided with a clamping member 5, the height position of the fixing frame 2 provides a certain height condition for the clamping member 5, so that after the clamping member 5 clamps the weight and releases the weight, the weight can fall at a certain height, and the weight falls and hits the ground to generate vibration.

[0051] The movable frame 3 is slidably connected to the column 1, and the movable frame 3 can move up and down along the length direction of the column 1. The driving component is used to drive the movable frame 3 to move along the length direction of the column 1. The driving end of the driving component is fixedly connected to the fixed frame 2. Since the fixed frame 2 is fixedly connected to the column 1, the movable frame 3 is slidably connected to the column 1. When the driving end of the driving component is extended and retracted, it will push the movable frame 3 in the opposite direction to move on the column 1, thereby realizing the driving of the movable frame 3 to move.

[0052] The movable frame 3 is in the shape of a frame. During the movement of the movable frame 3, it will contact the clamping member 5. During the contact with the clamping member 5, it will push the clamping member 5 to switch between the release state and the clamping state. In the clamping state, the clamping member 5 can clamp the weight. In the release state, the clamping member 5 releases the clamped weight at the height of the clamping member 5, so that the falling weight hits the ground and generates vibration.

[0053] The first position 6 and the second position 7 of the clamping member 5 are located at different positions, wherein when the movable frame 3 moves upward, it contacts the first position 6 of the clamping member 5, and when the movable frame 3 moves downward, it contacts the second position 7 of the clamping member 5. Thus, the clamping member 5 is switched between the clamping state and the releasing state.

[0054] Through the above arrangement, the movable frame 3 can be moved under the drive of the driving assembly. Specifically, the movable frame 3 can move upward or downward. When the movable frame 3 moves upward, it will contact the first position 6 of the clamping member 5 to put the clamping member 5 in a released state; when the movable frame 3 moves downward, it will contact the second position 7 of the clamping member 5 to put the clamping member 5 in a clamping state. When conducting seismic exploration, the clamping member 5 is first placed in a clamping state, the heavy hammer is hung, and then the driving assembly is controlled at the required time to convert the clamping member 5 from the clamping state to the releasing state, and the clamping member 5 releases the heavy hammer, thereby completing the operation. In this process, compared with the method of releasing the heavy hammer by hand-pulling unhooking, the solution of the present application saves more manpower, and releasing the heavy hammer by the clamping member 5 is more stable than the method of hand-pulling unhooking.

[0055] Reference Figure 3 , Figure 3 1 is a schematic diagram of the structure of the clamping member 5 proposed in one embodiment of the present application. In order to achieve the clamping of the weight, the specific structure of the clamping member 5 is further described. In some embodiments of the present application, the following configuration is provided:

[0056] The clamping member 5 includes two clamping claws 501, each of which is in the shape of a hook. Both of the clamping claws 501 are rotatably connected to the bottom of the fixing frame 2.

[0057] When the ends of the two clamping jaws 501 are close to and in contact with each other, the two clamping jaws 501 enclose and form an arc structure for supporting the heavy hammer, so that the clamping member 5 is in a clamping state; when the ends of the two clamping jaws 501 are away from each other, there is a gap between the two clamping jaws 501 for the heavy hammer to pass through, so that the clamping member 5 is in a released state.

[0058] The two clamping jaws 501 are both hook-shaped, and the arc-shaped openings of the two clamping jaws 501 are arranged opposite to each other, and the two clamping jaws 501 are both rotatably connected. The two clamping jaws 501 can be rotated until their ends contact each other, and can also be rotated until their ends move away from each other. When the ends of the two clamping jaws 501 contact each other, the two hook-shaped clamping jaws 501 are enclosed to form a semicircular frame structure, and the weight is suspended in this semicircular frame structure to achieve the clamping of the weight. When the two clamping jaws 501 move away from each other, the two clamping jaws 501 move away from each other so that a gap appears in the above-mentioned semicircular frame structure, and the existence of this gap allows the suspended weight to pass through, thereby achieving the release of the weight.

[0059] Reference Figure 3 In order to make the clamping jaw 501 rotate under the movement of the movable frame to achieve the switching between the clamping state and the release state, in some embodiments of the present application, the following settings are provided:

[0060] The clamping jaw 501 includes a connected rotating portion 5011 and a contact portion 5012, wherein the rotating portion 5011 is rotatably connected to the bottom of the fixed frame 2, and the contact portion 5012 is located on the motion track of the movable frame 3;

[0061] Wherein, the first position 6 is located on the contact portion 5012, and the second position 7 is located on the rotating portion 5011;

[0062] The movable frame 3 includes a connecting portion 301 and a pushing portion 302, wherein the connecting portion 301 is slidably connected to the column 1, and the pushing portion 302 is located at the bottom of the connecting portion 301, and the pushing portion 302 is used to contact the first position 6 and the second position 7;

[0063] When the pushing portion 302 moves upward to contact the first position 6 of the contact portion 5012, the ends of the two clamping jaws 501 move away from each other; when the pushing portion 302 moves downward to contact the second position 7 of the rotating portion 5011, the ends of the two clamping jaws 501 approach and contact each other.

[0064] The rotating portion 5011 is rotatably connected to the bottom of the fixing frame 2 . Since the rotating portion 5011 and the contact portion 5012 are connected to form a single clamping jaw 501 , the rotation of the rotating portion 5011 also drives the contact portion 5012 to rotate.

[0065] The first position 6 is set on the contact portion 5012, and the contact portion 5012 is located on the upward movement trajectory of the movable frame 3, so the movable frame 3 will contact the contact portions 5012 on both clamping jaws 501 when moving, pushing the two clamping jaws 501 to rotate, so that the ends of the two clamping jaws 501 move away from each other.

[0066] The second position 7 is arranged on the rotating part 5011, and when the movable frame 3 moves downward, the movable frame 3 will contact the second position 7 of the rotating part 5011 of the two clamping jaws 501, and the movable frame 3 presses the two clamping jaws 501 tightly, so that the ends of the two clamping jaws 501 are in contact and cannot be separated, thereby making the weight suspended between the two clamping jaws 501 unable to be separated.

[0067] Reference Figure 1 and Figure 2 In order to achieve the fixation between the fixed frame 2 and the column 1 and the sliding connection between the movable frame 3 and the column 1, in some embodiments of the present application, the following settings are provided:

[0068] The device also includes:

[0069] A first sleeve 8 and a second sleeve 9 are provided on the column 1, wherein the first sleeve 8 is fixedly connected to the column 1 and the fixing frame 2 respectively;

[0070] The second sleeve 9 is slidably connected to the column 1 , and the second sleeve 9 is fixedly connected to the movable frame 3 , and the second sleeve 9 is located above the first sleeve 8 .

[0071] The first sleeve 8 is fixedly connected to the fixing frame 2 and is fixed to the column 1 .

[0072] The second sleeve 9 extends toward the movable frame 3 from one side close to the movable frame 3 and is fixedly connected to the movable frame 3. The inner diameter of the second sleeve 9 is larger than the diameter of the column 1, so the second sleeve 9 can slide in the length direction of the column 1, and the setting of the two columns 1 guides the sliding of the second sleeve 9.

[0073] Reference Figure 1 and Figure 2 In order to ensure the stability of the fixed frame 2 and the movable frame 3, in some embodiments of the present application, the following settings are provided:

[0074] There are two columns 1 , and the fixed frame 2 and the movable frame 3 are both located between the two columns 1 .

[0075] The first sleeve 8 and the second sleeve 9 are both cylindrical, wherein the first sleeve 8 and the second sleeve 9 are both sleeved on the outer side of the column 1. There are two columns 1, which are arranged in parallel, and a first sleeve 8 is arranged on each of the two columns 1. The fixed frame 2 and the movable frame 3 are both located between the two horizontally arranged columns 1. The arrangement of the two columns 1 enhances the stability of the fixed frame 2 and improves the stability of the movable frame 3 during the sliding process.

[0076] In order to facilitate the disassembly between the fixed frame 2, the movable frame 3 and the column 1, in some embodiments of the present application, the following settings are provided:

[0077] The first sleeve 8 and the second sleeve 9 are both detachably connected to the column 1 .

[0078] The first sleeve 8 is cylindrical, wherein the inner diameter of the first sleeve 8 is close to the diameter of the column 1, and is tightly attached to the side surface of the first column 1. Therefore, after the first sleeve 8 is connected to the column 1, the friction force between the first sleeve 8 and the side surface of the column 1 realizes the fixation between the first sleeve 8 and the column 1.

[0079] The second sleeve 9 is also cylindrical, and the second sleeve 9 formed into a cylindrical shape also has two flanges arranged in contact, and the flanges are fixed by bolts and screws. The inner diameter of the second sleeve 9 is slightly larger than the diameter of the column 1, so after the first sleeve 8 is connected to the column 1, the second sleeve 9 can move on the column 1.

[0080] The first sleeve 8 and the second sleeve 9 are both mounted on the column 1 and are detachably connected to the column 1. When the height of the weight needs to be adjusted, the positions of the first sleeve 8 and the second sleeve 9 are adjusted simultaneously to complete the adjustment of the height of the weight. In this process, the column 1 plays a role in straightening and guiding.

[0081] In some embodiments of the present application, a sliding block may be further provided on the second sleeve 9, a sliding groove matching the sliding block is provided on the outer side of the column 1, and the sliding block is slidably connected to the sliding groove. The provision of the sliding groove and the sliding block further enhances the guiding effect of the sliding movement of the second sleeve 9.

[0082] Reference Figure 1 and Figure 2 , in some embodiments of the present application, has the following settings:

[0083] The fixing frame 2 includes a fixing frame 201 and two mounting plates 202;

[0084] The fixing frame 201 is arranged along the length direction of the column 1 , the two mounting plates 202 are connected to the bottom of the fixing frame 201 , and the clamping member 5 is rotatably connected between the two mounting plates 202 .

[0085] The shape of the fixed frame 201 is a rectangular frame, and the length direction of the rectangular frame is the same as the length direction of the column 1. The shape of the mounting plate 202 is a triangular plate, and the two mounting plates 202 are arranged in parallel, and the two clamping jaws 501 are rotatably connected between the two mounting plates 202. Specifically, the two clamping jaws 501 are partially rotatably connected between the two mounting plates 202, and this part is blocked by the mounting plate 202, and the rest part extends out of the mounting plate 202, and the contact portion 5012 extends in the direction close to one of the columns 1 and is located on the movement trajectory of the movable frame 3.

[0086] In order to realize the driving of the movable frame 3, in some embodiments of the present application, the following settings are provided:

[0087] The driving assembly includes a driving member 4, which is connected to the movable frame 3. The driving member 4 has a retractable pushing rod 10, and the retracting direction of the pushing rod 10 is the same as the length direction of the column 1. The end of the pushing rod 10 is connected to the fixed frame 2.

[0088] The driving member 4 is connected to the movable frame 3, and the driving member 4 has a retractable push rod 10. When the push rod 10 is extended outward, since the end of the push rod 10 is connected to the fixed frame 2, and the movable frame 3 is slidably connected to the column 1, the pushing rod 10 will drive the driving member 4 and the movable frame 3 to move upward in the opposite direction when it is extended downward, thereby realizing the upward movement of the movable frame 3. When the pushing rod 10 is retracted, it will drive the driving member 4 to move downward, and the downward movement of the driving member 4 will drive the movable frame 3 fixedly connected thereto to move downward at the same time.

[0089] In some embodiments of the present application, the following settings are provided:

[0090] The driving member 4 includes an electric cylinder, which is fixed on the movable frame 3 , and an output end of the electric cylinder is connected to the pushing rod 10 .

[0091] Among them, the description of the electric cylinder is as follows: The electric cylinder is a modular product that integrates a servo motor and a lead screw, and is used to convert the rotational motion of the servo motor into linear motion.

[0092] The output end of the electric cylinder is fixedly connected to the push rod 10, so the push rod 10 can realize telescopic movement along with the extension and retraction of the output end of the electric cylinder.

[0093] In some other embodiments of the present application, the following configuration is provided: the driving member 4 may also be a cylinder, the cylinder is fixed on the movable frame 3 , and the output end of the cylinder is fixedly connected to the push rod 10 .

[0094] Based on the same inventive concept, the present application also provides a weight release system for seismic exploration, the system comprising a weight and a weight release device for seismic exploration.

[0095] The weight can be clamped and suspended when the clamping member 5 of the weight releasing device for seismic exploration is in a clamping state, and fall off when the clamping member 5 is in a releasing state.

[0096] In general, this application has the following advantages:

[0097] On the one hand, the movable frame 3 can be moved under the drive of the driving component. Specifically, the movable frame 3 can move upward or downward. When the movable frame 3 moves upward, it will contact the first position 6 of the clamping member 5 to put the clamping member 5 in a released state; when the movable frame 3 moves downward, it will contact the second position 7 of the clamping member 5 to put the clamping member 5 in a clamping state. When conducting seismic exploration, the clamping member 5 is first placed in a clamping state, the heavy hammer is hung, and then the driving component is controlled at the required time to convert the clamping member 5 from the clamping state to the releasing state, and the clamping member 5 releases the heavy hammer, thereby completing the operation. In this process, compared with the method of releasing the heavy hammer by hand-pulling unhooking, the solution of the present application saves more manpower, and releasing the heavy hammer by the clamping member 5 is more stable than the method of hand-pulling unhooking.

[0098] In the second aspect, the two clamping jaws 501 are both hook-shaped, and the arc-shaped openings of the two clamping jaws 501 are arranged opposite to each other, and the two clamping jaws 501 are both rotatably connected. The two clamping jaws 501 can be rotated until their ends contact each other, and can also be rotated until their ends move away from each other. When the ends of the two clamping jaws 501 contact each other, the two hook-shaped clamping jaws 501 are enclosed to form a circular frame structure, and the weight is suspended in this circular frame structure to achieve the clamping of the weight. When the two clamping jaws 501 move away from each other, the two clamping jaws 501 move away from each other so that a gap appears in the above-mentioned circular frame structure, and the existence of this gap allows the suspended weight to pass through, thereby achieving the release of the weight.

[0099] In the third aspect, the first sleeve 8 and the second sleeve 9 are both cylindrical, wherein the first sleeve 8 and the second sleeve 9 are both sleeved on the outer side of the column 1. There are two columns 1, and the two columns 1 are arranged in parallel. A first sleeve 8 is arranged on each of the two columns 1, and the fixed frame 2 and the movable frame 3 are both located between the two horizontally arranged columns 1. The arrangement of the two columns 1 enhances the stability of the fixed frame 2 and improves the stability of the movable frame 3 during the sliding process.

[0100] Fourthly, the first sleeve 8 and the second sleeve 9 are both mounted on the column 1 and are detachably connected to the column 1. When the height of the weight needs to be adjusted, the positions of the first sleeve 8 and the second sleeve 9 are adjusted at the same time to complete the adjustment of the height of the weight. In this process, the column 1 plays a role in straightening and guiding.

[0101] In the fifth aspect, the driving member 4 is connected to the movable frame 3, and the driving member 4 has a retractable push rod 10. When the push rod 10 is extended outward, since the end of the push rod 10 is connected to the fixed frame 2, and the movable frame 3 is slidably connected to the column 1, when the push rod 10 is extended downward, it will drive the driving member 4 and the movable frame 3 to move upward in the opposite direction, thereby realizing the upward movement of the movable frame 3. When the push rod 10 is retracted, it will drive the driving member 4 to move downward, and the downward movement of the driving member 4 will drive the movable frame 3 fixedly connected thereto to move downward at the same time.

[0102] It should also be noted that, in this article, the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations, nor can they be understood as indicating or implying relative importance.
