Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of geological exploration, in particular to an elastic wave detector exploration equipment for power transmission engineering karst exploration. BACKGROUND

[0002] With the rapid economic development, the demand for electricity gradually increases, and more and more power transmission lines need to be built. The foundation, tower foundation and other foundations of the power transmission line substation need to reach a certain bearing capacity to meet the safety needs of the project. However, China is a country with widely distributed karst development. In the construction of power transmission line foundation engineering, the problem of passing through karst areas is often encountered. In order to ensure the safety needs of the power transmission line substation foundation, tower foundation and other foundation engineering, when building the substation foundation, tower foundation and other foundations in the karst area, it is necessary to use the elastic wave detection method to detect the karst and other adverse geology.

[0003] The specific operation of the current elastic wave detection method is as follows: according to the requirements of engineering practice, each detector is arranged, and the interval is measured and positioned by manual one by one during the period, and then the detectors are connected by cables, and then data collection is carried out through the detectors, and the detection of a geological profile is completed; in this way, when each geological profile is detected, the interval of each detector needs to be repositioned, and the detector is manually transported and arranged, and the cable is manually connected to each detector. A power transmission line engineering project often needs to involve the detection of dozens to hundreds of geological profiles, which makes the current elastic wave detection method not only time-consuming and laborious, but also inefficient, and it is difficult to meet the requirements of rapid construction in the power transmission line. On the other hand, the current elastic wave detection method only relies on the gravity of the detector itself to contact the ground to realize coupling, which often has the problem of poor coupling. In order to ensure that the detector is in close contact with the ground, manual compaction is usually required before data collection. SUMMARY

[0004] The purpose of the present application is to provide an elastic wave detector exploration equipment for power transmission engineering karst exploration, which can effectively improve the detection operation efficiency, reduce the labor intensity of the detection operation, and effectively ensure the close contact and coupling of the detector with the ground in the detection operation.

[0005] The technical scheme of the present application is:

[0006] The utility model provides a kind of elastic wave detector exploration equipment for transmission engineering karst exploration, including several sequentially connected mobile trolley and one-to-one corresponding elastic exploration device arranged on mobile trolley, elastic exploration device includes lifting frame, for lifting the lifting actuator of the lifting frame, the vertical sleeve being set on lifting frame, along vertical sleeve up and down sliding float column, for the first compression spring of float column down pressure and the detector being set in the lower end of float column, the detector on each mobile trolley is connected by cable.This utility model's elastic wave detector exploration equipment for transmission engineering karst exploration when using, by manual traction mode or by power car head traction mode drives each mobile trolley moves in position;Then, lifting actuator drives lifting frame to descend, lifting frame drives vertical sleeve, float column, first compression spring and detector synchronous down, so that detector is in contact with ground;Then, lifting actuator continues to drive lifting frame to descend, by vertical sleeve compression first compression spring, so as to be pressed tightly on ground by first compression spring to detector, to ensure that detector and ground are closely contacted and coupled in detection operation;Then data acquisition is carried out by detector;Then, lifting actuator drives lifting frame, vertical sleeve, float column, first compression spring and detector up reset, then by manual traction mode or by power car head traction mode drives each mobile trolley to next detection position moves.This utility model's elastic wave detector exploration equipment for transmission engineering karst exploration in detection process, without measuring the interval positioning of each detector, without manual handling and arranging detector, without manual cable connection each detector, so as to effectively improve detection operation efficiency, reduce detection operation intensity, while effectively ensuring that detector and ground are closely contacted and coupled in detection operation.

[0007] As preferred, it further comprises an exploration device locking mechanism, which comprises a vertical guide hole arranged on the lifting frame, a vertical locking rod sliding along the vertical guide hole, a locking rod upper limiting block arranged on the vertical locking rod and located above the lifting frame, an annular stopper arranged on the vertical locking rod and located below the lifting frame, and a second compression spring sleeved on the vertical locking rod, with the upper end of the second compression spring abutting against the lifting frame and the lower end of the second compression spring abutting against the annular stopper. During the process of lowering the lifting frame driven by the lifting actuator, the lower end of the vertical locking rod first contacts the ground, and then the detector contacts the ground. In this way, the lower end of the vertical locking rod can first contact the ground without affecting the close contact and coupling of the detector with the ground, so as to lock the mobile trolley in place by the vertical locking rod, avoiding the damage of the detector caused by the movement of the mobile trolley during the detection process after the detector contacts the ground. Moreover, the same lifting actuator is used to drive the vertical locking rod and the detector to perform lifting work, which not only can save cost, but also can avoid the mistakes caused by the non-standard operation of multiple lifting actuators, such as forgetting to drive the vertical locking rod to descend and contact the ground.

[0008] As preferred, the lower end of the vertical locking rod is provided with a pointed cone. In this way, after the lower end of the vertical locking rod contacts the ground, the mobile trolley is locked in place.

[0009] As preferred, a power car head is further included, which is connected with one of the mobile trolleys at the end, and is used to drive the mobile trolleys to move. In this way, the power car head can be used to drive the mobile trolleys to move.

[0010] As preferred, an anti-misdragging self-unlocking connection structure is further included, which connects the power car head and the mobile trolley at the end. The anti-misdragging self-unlocking device includes a floating connecting column, and a trolley connecting piece, a car head connecting piece and a support flat plate arranged in sequence from top to bottom. The trolley connecting piece is connected with the mobile trolley close to the power car head, and is provided with a vertical upper connecting hole. The car head connecting piece is connected with the power car head, and is provided with a vertical lower connecting hole. The support flat plate is connected with the lifting frame on the mobile trolley close to the power car head. The floating connecting column is inserted into the vertical upper connecting hole and the vertical lower connecting hole, and the lower end of the floating connecting column is supported on the support flat plate.

[0011] After the lifting execution mechanism on the mobile trolley connected with the power car head drives the lifting frame to move downward to the position, the upper end of the floating connecting column is located below the vertical upper connecting hole, so that the floating connecting column is separated from the vertical upper connecting hole.

[0012] Although the power car head is used to drive the mobile trolleys to move, it is convenient to operate, but there is a problem that the detector is damaged due to the misoperation of the operator. Specifically, during the process of coupling with the ground for detection behind each detector, if the operator mistakenly drives the power car head to drive the mobile trolley to move forward, the detector may be damaged. In order to solve this problem, the inventor designs the anti-misdragging self-unlocking connection structure. Since the lower end of the floating connecting column is supported on the support flat plate, when the lifting execution mechanism on the mobile trolley connected with the power car head drives the lifting frame to move downward to the position, the floating connecting column is separated from the vertical upper connecting hole. In this way, during the process of coupling with the ground for detection behind each detector, even if the operator mistakenly drives the power car head to drive the mobile trolley to move forward, at this time, since the floating connecting column is separated from the vertical upper connecting hole, the power car head will move forward alone and will not drive the mobile trolley to move forward, thereby effectively solving this problem. More importantly, the anti-misdragging self-unlocking connection structure automatically realizes the connection and unlocking of the power car head and the mobile trolley with the action of the lifting frame of the elastic exploration device, without the need for independent control of the action of the anti-misdragging self-unlocking connection structure. In this way, not only the operation control is simplified, but also the problem that the anti-misdragging self-unlocking connection structure cannot work due to forgetting to control the action of the anti-misdragging self-unlocking connection structure can be avoided.

[0013] As preferred, the upper end of the floating connecting column is provided with a conical guide part with a gradually decreasing outer diameter from bottom to top. In this way, the floating connecting column is facilitated to be inserted into the vertical upper connecting hole upward during the upward movement of the lifting frame.

[0014] As preferred, the moving trolley is provided with a translation guide rail, a translation slide moving along the translation guide rail, and a slide locking structure for locking the translation slide on the translation guide rail, the lifting frame is located below the corresponding translation slide of the moving trolley, and the lifting actuator is arranged on the translation slide. In this way, the position of the elastic exploration device on the moving trolley can be adjusted as needed.

[0015] As preferred, the elastic exploration device further comprises a vertical guide rod and an upper guide rod limiting block and a lower guide rod limiting block arranged on the vertical guide rod, the upper end of the vertical guide rod is fixed on the translation slide, the lifting frame is provided with a vertical guide sleeve matched with the vertical guide rod, and the vertical guide sleeve is located between the upper guide rod limiting block and the lower guide rod limiting block.

[0016] As preferred, the inner wall of the vertical sleeve is provided with a limiting groove extending along the axial direction of the vertical sleeve, the outer wall of the floating column is provided with a limiting block matched with the limiting groove, the first compression spring is located in the vertical sleeve, the lower end of the first compression spring abuts against the upper end of the floating column, and the upper end of the first compression spring abuts against the inner top surface of the vertical sleeve.

[0017] The present application has the advantages of effectively improving the detection operation efficiency, reducing the labor intensity of the detection operation, and effectively ensuring the close contact and coupling between the detector and the ground in the detection operation.

[0027] Specific embodiment one: as shown in Figure 1 , Figure 2 A kind of elastic wave detector exploration equipment for power transmission engineering karst exploration, including a plurality of sequentially connected mobile trolleys 1 and one-to-one corresponding elastic exploration devices 2 arranged on the mobile trolley. The elastic exploration device includes a lifting frame 2.1, a lifting actuator 2.2 for lifting the lifting frame, a vertical sleeve 2.3 arranged on the lifting frame, a floating column 2.4 sliding up and down along the vertical sleeve, a first compression spring 2.5 for pressing the floating column downward, and a detector 2.6 arranged at the lower end of the floating column. The detectors on each mobile trolley are connected by a cable, i.e. the detectors on each mobile trolley are connected in series by a cable.

[0028] In this embodiment, the elastic wave detector exploration equipment for karst exploration in power transmission engineering is used by manually pulling or using a powered vehicle to move each trolley into position. Then, the lifting mechanism drives the lifting frame to descend, causing the vertical sleeve, floating column, first compression spring, and detector to move synchronously downwards, bringing the detector into contact with the ground. Next, the lifting mechanism continues to drive the lifting frame downwards, compressing the first compression spring through the vertical sleeve, thereby pressing the detector firmly against the ground to ensure tight contact and coupling between the detector and the ground during the exploration operation. Data is then acquired through the detector. Next, the lifting mechanism drives the lifting frame, vertical sleeve, floating column, first compression spring, and detector to move upwards and reset, and then each trolley is moved to the next exploration position by manually pulling or using a powered vehicle. The elastic wave detector exploration equipment for karst exploration in this scheme eliminates the need to measure the spacing and positioning of each detector, manually transport and arrange the detectors, or manually connect the detectors with cables during the exploration process. Therefore, it can effectively improve the efficiency of the exploration operation, reduce the labor intensity of the exploration operation, and effectively ensure that the detectors are in close contact and coupled with the ground during the exploration operation.

[0029] Specifically, the inner wall of the vertical sleeve is provided with a limiting groove extending along the axial direction of the vertical sleeve, and the outer wall of the floating column is provided with a limiting stop 2.11 that cooperates with the limiting groove. The lower end of the vertical sleeve is open, and the upper end of the vertical sleeve is closed. The lower end of the floating column is located below the lower end of the vertical sleeve. The first compression spring is located inside the vertical sleeve, with its lower end abutting against the upper end of the floating column and its upper end abutting against the inner top surface of the vertical sleeve.

[0030] In this embodiment, the lifting actuator is a lifting cylinder or an electric cylinder.

[0031] In this embodiment, the elastic wave detector exploration equipment for karst exploration in power transmission projects also includes a power unit 3. The power unit is connected to one of the mobile trolleys located at the end of each mobile trolley, and is used to drive each mobile trolley to move. In this way, the power unit can drive each mobile trolley to move.

[0032] Furthermore, such as Figure 1 , Figure 2 As shown, the mobile trolley is equipped with a translation guide rail 1.1, a translation slide 1.2 that moves along the translation guide rail, and a slide locking structure 1.3 for locking the translation slide onto the translation guide rail. The flexible exploration device is mounted on the corresponding translation slide of the mobile trolley. The lifting frame is located below the corresponding translation slide of the mobile trolley. The lifting actuator is mounted on the translation slide. Thus, the position of the flexible exploration device on the mobile trolley can be adjusted as needed.

[0033] In the embodiment, the translation guide rail extends along the front-rear direction of the moving trolley. The slide locking structure is a locking bolt arranged on the translation slide, the locking bolt is vertically distributed, and the locking bolt penetrates the translation slide. By locking the locking bolt, the lower end of the locking bolt is abutted on the body of the moving trolley, and the translation slide is locked on the translation guide rail.

[0034] The elastic exploration device further comprises a vertical guide rod 2.7 and a guide rod upper limiting block 2.8 and a guide rod lower limiting block 2.9 arranged on the vertical guide rod. The upper end of the vertical guide rod is fixed on the translation slide. The lifting frame is provided with a vertical guide sleeve 2.10 matched with the vertical guide rod, and the vertical guide sleeve is located between the guide rod upper limiting block and the guide rod lower limiting block.

[0035] When the vertical guide sleeve abuts on the guide rod upper limiting block, the limiting block abuts on the lower end of the limiting groove, and the detector is located above the ground and separated from the ground. When the vertical guide sleeve abuts on the guide rod lower limiting block, the limiting block is separated from the lower end of the limiting groove, and the detector is in contact with the ground.

[0036] Further, as shown in Figure 1 , Figure 2 The elastic wave detector exploration equipment for power transmission engineering karst exploration further comprises an exploration device locking mechanism 4. The exploration device locking mechanism comprises a vertical guide hole arranged on the lifting frame, a vertical locking rod 4.1 sliding along the vertical guide hole, a locking rod upper limiting block 4.2 arranged on the vertical locking rod and located above the lifting frame, an annular block 4.3 arranged on the vertical locking rod and located below the lifting frame, and a second compression spring 4.4 sleeved on the vertical locking rod. The upper end of the second compression spring abuts on the lifting frame, and the lower end of the second compression spring abuts on the annular block. In the embodiment, when the vertical guide sleeve abuts on the guide rod lower limiting block, the lower end of the vertical locking rod is in contact with the ground. During the process of the lifting actuator driving the lifting frame to move downward, the lower end of the vertical locking rod is in contact with the ground first, and then the detector is in contact with the ground. In this way, the lower end of the vertical locking rod can be in contact with the ground first without affecting the close contact and coupling of the detector with the ground, so as to lock the moving trolley in place by the vertical locking rod, thereby avoiding the damage of the detector caused by the movement of the moving trolley during the process of the detector being in contact with the ground for detection. Moreover, the same lifting actuator is used to drive the vertical locking rod and the detector to work, which not only can save cost, but also can avoid the mistakes caused by the non-standard operation of multiple lifting actuators, such as forgetting to drive the vertical locking rod to move downward and contact with the ground.

[0037] In the embodiment, the lower end of the vertical locking rod is provided with a sharp cone. In this way, after the lower end of the vertical locking rod is in contact with the ground, the moving trolley can be locked in place.

[0038] Further, as shown in Figure 1 ,Figure 3 As shown, the elastic wave detector exploration equipment for power transmission engineering karst exploration further comprises an anti-misdragging self-unlocking connecting structure 5. The power car head and the mobile trolley located at one end are connected through the anti-misdragging self-unlocking connecting structure. The anti-misdragging unlocking device comprises a floating connecting column 5.1 and a trolley connecting piece 5.2, a car head connecting piece 5.3 and a support flat plate 5.4 distributed in sequence from top to bottom. The trolley connecting piece is connected with the mobile trolley close to the power car head. The trolley connecting piece is provided with a vertical upper connecting hole. The car head connecting piece is connected with the power car head, and the car head connecting piece is provided with a vertical lower connecting hole. The vertical upper connecting hole is located directly above the vertical lower connecting hole. The support flat plate is connected with the lifting frame on the mobile trolley close to the power car head. The floating connecting column is inserted into the vertical upper connecting hole and the vertical lower connecting hole, and the lower end of the floating connecting column is supported on the support flat plate. In the embodiment, the support flat plate is in the shape of a long strip, and the length direction of the support flat plate is parallel to the translation guide rail. The support flat plate is horizontally distributed.

[0039] After the lifting execution mechanism on the mobile trolley connected with the power car head drives the lifting frame to move downward to the position, the upper end of the floating connecting column is located below the vertical upper connecting hole, so as to separate the floating connecting column from the vertical upper connecting hole, and at this time, the floating connecting column remains inserted into the vertical lower connecting hole; specifically, after the lifting execution mechanism on the mobile trolley connected with the power car head drives the lifting frame to move downward, and the vertical guide sleeve abuts against the lower limiting block of the guide rod, the upper end of the floating connecting column is located below the vertical upper connecting hole, so as to separate the floating connecting column from the vertical upper connecting hole, and at this time, the floating connecting column remains inserted into the vertical lower connecting hole.

[0040] Although the operation is convenient, the power car head drives the mobile trolley to move, but there is a problem of causing the detector to be damaged due to the misoperation of the operator. Specifically, during the process of coupling with the ground behind each detector for detection, if the operator mistakenly drives the power car head to drive the mobile trolley to move forward, the detector may be damaged. In order to solve this problem, the inventor designs a mistaken dragging prevention and self-unlocking connection structure. Since the lower end of the floating connecting column is supported on the supporting plate, when the lifting mechanism on the mobile trolley connected with the power car head drives the lifting frame to move down to the position, the floating connecting column is separated from the vertical upper connecting hole. Thus, during the process of coupling with the ground behind each detector for detection, even if the operator mistakenly drives the power car head to drive the mobile trolley to move forward, at this time, since the floating connecting column is separated from the vertical upper connecting hole, the power car head will move forward alone and will not drive the mobile trolley to move forward, thereby effectively solving this problem. More importantly, the mistaken dragging prevention and self-unlocking connection structure automatically realizes the connection and unlocking of the power car head and the mobile trolley with the action of the lifting frame of the elastic exploration device, without the need for independent control of the action of the mistaken dragging prevention and self-unlocking connection structure. Thus, not only is the operation control simplified, but also the problem that the mistaken dragging prevention and self-unlocking connection structure cannot work due to forgetting to control the action of the mistaken dragging prevention and self-unlocking connection structure can be avoided.

[0041] In the embodiment, the upper end of the floating connecting column is provided with a tapered guide portion with a gradually decreasing outer diameter from bottom to top. Thus, during the upward movement of the lifting frame, the floating connecting column is beneficially inserted into the vertical upper connecting hole. Specifically, when the vertical guide sleeve abuts against the limiting block on the guide rod, the floating connecting column is inserted into the vertical upper connecting hole and the vertical lower connecting hole.

[0042] The above is only a preferred embodiment of the present application, and does not limit the present application in any way. Any simple modification, change and equivalent transformation of the above embodiment according to the technical essence of the present application still belongs to the protection scope of the technical solution of the present application.
