Description

Technical Field

[0001] This application relates to the field of controllable vibration source equipment technology, and in particular to a controllable vibration source lifting and movable counterweight device. Background Technology

[0002] When a controlled seismic source vehicle travels on highways during field construction, especially on paved roads in mountainous areas, its excessive weight may prevent it from meeting the crossing requirements of some bridges. Therefore, the vehicle's weight needs to be reduced during the design phase. However, to better transmit seismic waves underground, the controlled seismic source requires a certain mass of the vehicle body to weigh down the vibrating plate and improve coupling between the plate and the ground. Therefore, counterweights are used to adjust the vehicle's weight, reducing its weight during transit and increasing it during construction.

[0003] Regarding the aforementioned technologies, the traditional method of counterweighting involves installing square tubes extending laterally to both sides at the bottom of the frame, and then manually adding counterweight plates to these tubes. When crossing some bridges, the counterweights need to be temporarily removed and then reinstalled after crossing the bridge. This manual method of installing counterweight plates is extremely inconvenient, and the operation takes place in a confined space under the vehicle, posing a safety risk. Summary of the Invention

[0004] Therefore, it is necessary to provide a controllable seismic source lifting and movable counterweight device that can conveniently install and remove the counterweight of the controllable seismic source vehicle.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution: A controllable vibration source lifting and movable counterweight device includes: counterweight; The adsorption section, on the side opposite to the counterweight section, is used to adsorb onto the vehicle. The lifting part, located between the counterweight part and the lifting part, includes a first movable end, a second movable end and a lifting assembly. The first movable end is connected to the counterweight part, the second movable end is connected to the adsorption part, and the lifting assembly adjusts the distance between the first movable end and the second movable end.

[0006] Understandably, by adjusting the distance between the counterweight and the adsorption unit through the lifting mechanism, and since the counterweight is located on one side of the ground, the lifting mechanism moves the adsorption unit toward the side of the vehicle chassis. The adsorption unit then adsorbs the entire device onto the vehicle. Once the adsorption is stable, the lifting mechanism moves the counterweight at the bottom toward the side closer to the vehicle chassis, causing the counterweight to detach from the ground, thus installing the counterweight onto the vehicle. When it is necessary to unload the counterweight, the lifting mechanism moves the counterweight downwards, causing it to contact the ground. At this point, the adsorption unit disconnects from the vehicle chassis, thus detaching the counterweight from the vehicle. This allows for convenient installation and removal of the counterweight on the controllable vibration source vehicle.

[0007] In one embodiment, the counterweight includes a first counterweight plate, on which a counterweight block is mounted, and the first movable end is disposed on the first counterweight plate.

[0008] In one embodiment, the first counterweight plate and the first counterweight block are detachably connected.

[0009] In one embodiment, the counterweight further includes a counterweight chassis connected to the counterweight block, and the counterweight chassis is used to drive the counterweight to move.

[0010] In one embodiment, the adsorption unit includes a second counterweight plate and an adsorption member. The second counterweight plate is connected to the second movable end, and the adsorption member is installed on the side of the second counterweight plate away from the lifting unit, so that the lifting unit and the counterweight unit are adsorbed to the vehicle through the adsorption member.

[0011] In one embodiment, multiple adsorption elements are disposed on the side wall of the second counterweight plate.

[0012] In one embodiment, a fastener is provided on the second counterweight plate, the fastener being used to connect the second counterweight plate to the vehicle.

[0013] In one embodiment, the lifting assembly includes a first hinge rod, a second hinge rod, and a driving member. The first hinge rod and the second hinge rod are hinged together. The two ends of the first hinge rod are respectively hinged to the counterweight and the adsorption part. The two ends of the second hinge rod slide with the counterweight and the adsorption part, respectively. The movable end of the driving member is connected to the second hinge rod, so that the driving member drives the angle between the first hinge rod and the second hinge rod to change.

[0014] In one embodiment, a roller is mounted on the end of the second hinge rod, and a sliding frame is fixedly connected to the side of the counterweight near the roller, with the roller located inside the sliding frame.

[0015] In one embodiment, the counterweight is provided with a first locking member, and the adsorption part is provided with a second locking member, and the counterweight and the adsorption part can be locked by the first locking member and the second locking member.

[0016] Compared with existing technologies, a controllable vibration source lifting and movable counterweight device adjusts the distance between the counterweight and the adsorption part through a lifting part. Since the counterweight is located on one side of the ground, the lifting part drives the adsorption part to move towards the side of the vehicle chassis. The adsorption part adsorbs the entire device onto the vehicle. After the adsorption is stable, the lifting part drives the counterweight at the bottom to move towards the side closer to the vehicle chassis, so that the counterweight is lifted off the ground and installed on the vehicle. When it is necessary to unload the counterweight, the lifting part drives the counterweight to move downward so that the counterweight contacts the ground. At this time, the adsorption part breaks the adsorption between the adsorption part and the vehicle chassis, so that the counterweight is detached from the vehicle. This allows for convenient installation and removal of the counterweight for the controllable vibration source vehicle. Attached Figure Description

[0026] When a controlled seismic source vehicle travels on highways during field construction, especially on paved roads in mountainous areas, its excessive weight may prevent it from meeting the crossing requirements of some bridges. Therefore, the vehicle's weight needs to be reduced during the design phase. However, to better transmit seismic waves underground, the controlled seismic source requires a certain mass of the vehicle body to weigh down the vibrating plate and improve coupling between the plate and the ground. Therefore, counterweights are used to adjust the vehicle's weight, reducing its weight during transit and increasing it during construction.

[0027] Regarding the aforementioned technologies, the traditional method of counterweighting involves installing square tubes extending laterally to both sides at the bottom of the frame, and then manually adding counterweight plates to these tubes. When crossing some bridges, the counterweights need to be temporarily removed and then reinstalled after crossing the bridge. This manual method of installing counterweight plates is extremely inconvenient, and the operation takes place in a confined space under the vehicle, posing a safety risk.

[0028] Therefore, it is necessary to provide a controllable seismic source lifting and movable counterweight device that can conveniently install and remove the counterweight of the controllable seismic source vehicle.

[0029] Please see Figures 1 to 2 This application provides a controllable vibration source lifting and movable counterweight device, including a counterweight part 1 for bearing the counterweight, a lifting part 2 located above the counterweight part 1, and an adsorption part 3 located on the side of the lifting part 2 away from the counterweight part 1, such that one end of the lifting part 2 is connected to the adsorption part 3, and the other end of the lifting part 2 is connected to the counterweight part 1. The bottom end of the counterweight part 1 can be supported on the ground, so that the lifting part 2 can drive the adsorption part 3 to move along the height direction, and the lifting and movable counterweight device can be adsorbed onto the vehicle by the adsorption part 3, so as to meet the vehicle installation counterweight requirements.

[0030] In a specific embodiment, the counterweight unit 1 includes a counterweight chassis 11, which is a movable vehicle chassis. The counterweight chassis 11 includes rollers 233, which can drive the counterweight chassis 11 to move, thereby driving the entire device to move, making it convenient to move the counterweight device to the bottom of the vehicle for the installation and removal of the counterweight.

[0031] A counterweight block 12 is also provided above the counterweight chassis 11. The counterweight block 12 is used to form a counterweight. In one embodiment, the counterweight block 12 and the counterweight chassis 11 are detachably installed, so that the counterweight block 12 of different masses can be adjusted according to different needs. In another embodiment, the counterweight block 12 and the counterweight chassis 11 can also be a fixed installation structure. The counterweight chassis 11 also serves as a counterweight, and the fixation of the counterweight block 12 and the counterweight chassis 11 can make the installation of the counterweight block 12 on the counterweight chassis 11 more stable.

[0032] A first counterweight plate 13 is horizontally positioned above the counterweight block 12. The first counterweight plate 13 is fixedly connected to the counterweight block 12, and its horizontal cross-sectional area is larger than that of the counterweight block 12. The first counterweight plate 13 can also function as a counterweight to balance the weight of the vehicle.

[0033] The adsorption unit 3 includes a horizontally arranged second counterweight plate 31, which is located above the first counterweight plate 13, and the projection of the second counterweight plate 31 along the vertical direction coincides with that of the first counterweight plate 13. The lifting unit 2 is located between the first counterweight plate 13 and the second counterweight plate 31, and is used to adjust the distance between the first counterweight plate 13 and the second counterweight plate 31, that is, to adjust the height of the first counterweight plate 13.

[0034] An adsorption component 32 is fixedly connected to the top wall of the second counterweight plate 31. In a specific embodiment, the adsorption component 32 can be an electromagnetic adsorption method, where four or more electromagnetic chucks are installed on the second counterweight plate 31. The strong magnetic force of the electromagnetic chucks is used to adsorb the counterweight plate onto the mounting position of the controllable vibration source vehicle, making the operation simple and convenient. Alternatively, a vacuum adsorption method can be used: multiple vacuum chucks are installed on the second counterweight plate 31, and a vacuum pump generates negative pressure, causing the vacuum chucks to adhere tightly to the mounting position of the controllable vibration source vehicle. The adsorption force can be adjusted according to the vacuum level, ensuring stable adsorption and minimizing susceptibility to environmental influences. By adsorbing the second counterweight plate 31 onto the vehicle using the adsorption component 32, the vehicle's counterweight is increased.

[0035] A fixing member 33 is also provided on the side wall of the second counterweight plate 31. The fixing member 33 is used to stabilize the second counterweight plate 31 with the vehicle after it is attracted and stabilized. In a specific embodiment, the fixing member 33 can be a bolt. Four or more bolt holes are provided on the second counterweight plate 31. The second counterweight plate 31 is fixedly connected to the mounting holes of the controllable vibration source vehicle by bolts, ensuring that the counterweight device is stably suspended under the vehicle frame. Since the controllable vibration source generates artificial seismic waves by its own vibration when it works, in addition to the attraction device, bolts are also needed for a stable connection, providing double protection to prevent the counterweight from falling off.

[0036] In some embodiments, the lifting part 2 may include a first movable end 21, a second movable end 22 and a lifting assembly 23. The lifting assembly 23 can adjust the distance between the first movable end 21 and the second movable end 22. The first movable end 21 is connected to the first counterweight plate 13 and the second movable end 22 is connected to the second movable plate. Thus, the lifting assembly 23 adjusts the distance between the first counterweight plate 13 and the second counterweight plate 31.

[0037] In some other embodiments, the lifting part 2 may only include a lifting assembly 23, one end of which is connected to the first counterweight plate 13 and the other end is connected to the second counterweight plate 31. The lifting assembly 23 can adjust the distance between the first counterweight plate 13 and the second counterweight plate 31, that is, adjust the height of the first counterweight plate 13, so as to facilitate the adsorption member 32 located on the first counterweight plate 13 to be adsorbed onto the vehicle.

[0038] The lifting assembly 23 includes a first hinge rod 231 and a second hinge rod 232 that are hinged to each other. One end of the first hinge rod 231 is hinged to the side wall of the first counterweight plate 13, and the other end is hinged to the side wall of the second counterweight plate 31. Both ends of the second counterweight plate 31 are slidably connected to the first counterweight plate 13 and the second counterweight plate 31, respectively. In a specific embodiment, a roller 233 can also be rotatably connected to the end of the second hinge rod 232. A sliding frame 14 is also fixedly connected to the side wall of the first counterweight plate 13. The sliding frame 14 is a rectangular frame structure, and the roller 233 opposite to the sliding frame 14 is located inside the sliding frame 14 and is relatively tumbling connected. This improves the rolling effect between the first hinge rod 231 and the first counterweight plate 13, and between the first hinge rod 231 and the second counterweight plate 31.

[0039] A driving component 234 is horizontally arranged on the second counterweight plate 31. In specific embodiments, the driving component 234 can be a cylinder, a hydraulic cylinder, or a linear guide, etc., which will not be listed here. The piston end of the driving component 234 is connected to the side wall of the second hinge rod 232, so that the driving component 234 drives the piston rod to move horizontally. In turn, the piston rod can drive the first hinge rod 231 and the second hinge rod 232 to rotate, thereby adjusting the height of the first counterweight platform and the second counterweight platform, and thus adjusting the height of the adsorption part 3 to facilitate the adsorption of vehicles.

[0040] A first locking element 15 is provided on the side wall of the first counterweight platform, and a second locking element 34 is provided on the side wall of the second counterweight platform. In a specific embodiment, the first locking element 15 is a locking head, and the second locking element is a locking seat. After the second counterweight plate 31 is fixed to the frame, the lifting assembly 23 is controlled to perform a reverse lifting action to raise the first counterweight plate 13 to the minimum position of the lifting assembly 23. Finally, the locking head is hooked onto the locking seat and fastened to ensure the stability of the counterweight system.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
