Description

Technical Field

[0001] The invention relates to the technical field of power facility foundation detection, in particular to a pull-out force detection device for designing a screw anchor in a prefabricated cabin of a transformer substation. Background Art

[0002] As we all know, the substation prefabricated cabin is a cabin-type equipment combination that is pre-manufactured in the factory, with standardized design and integrated production. Various electrical equipment in the substation are installed in a closed cabin. These cabins can be installed, wired, and debugged in the factory, and then transported to the substation site. They can be put into use after simple installation and connection.

[0003] As an important anchoring method, the accurate detection of the pull-out force of the spiral anchor is crucial to ensure the stability and safety of the prefabricated cabin. During the pull-out force detection of the spiral anchor, when the spiral anchor is subjected to tension during the pulling process, the hydraulic jacking equipment will generate a reverse force, which will act on the base of the detection device. When the base is on a soft surface soil layer, the reaction force will cause the base to sink into the soft ground, resulting in uncontrollable movement of the base position and even tilting of the base, making it difficult for the base to maintain a horizontal and stable state. At the same time, it will also affect the coaxiality of the spiral anchor during the pulling process, so that the originally precisely aligned pulling direction no longer coincides with the axis of the spiral anchor, resulting in eccentricity of the pull-out force, so that the spiral anchor is subjected to additional bending moment and uneven stress distribution during the detection process, thereby affecting the accuracy of the pull-out force detection. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a pull-out force detection device for a spiral anchor design in a prefabricated cabin of a substation, which has the advantages of being able to effectively cope with the influence of reaction force on soft ground, ensure the stability of the base, and ensure the coaxiality of the spiral anchor pull-out detection.

[0005] (II) Technical solution The above technical objectives of the present invention are achieved through the following technical solutions: A pull-out force detection device for a substation prefabricated cabin spiral anchor design, comprising a reaction base, both sides of the top of the reaction base are bolted with hydraulic cylinders, and a jacking rod is bolted between the tops of the two hydraulic cylinders, the bottom of the jacking rod is bolted with a sleeve, and the inside of the sleeve is bolted with a connecting plate, and the bottom of the connecting plate is provided with a connecting structure through a steel cable; The reaction force base includes an upper base and a lower base, the four corners of the lower base are penetrated by anchoring components, and the top of the anchoring components is connected to the upper base, and the upper base is connected to the hydraulic cylinder; The connecting structure includes a connecting column, which is located inside the sleeve, and a retaining component is sleeved on the top of the connecting column surface, and the retaining component is in contact with the inner wall of the sleeve on one side thereof, a clamping component is provided at the bottom of the connecting column, and a fixing component is provided inside the connecting column, and the fixing component is connected to the clamping component on one side thereof.

[0006] By adopting the above technical scheme, by setting up a reaction base, during the pull-out force detection of the spiral anchor, especially in the soft surface soil environment, the upper base and the lower base are connected by an anchoring assembly, and the anchoring assembly can penetrate deep into the soil and maintain good friction between the soil, so that the reaction base can adapt to the unevenness of the soft ground, buffer and disperse the reaction force generated by the pull-out force, and avoid the base from sinking into the ground or uncontrollable movement due to the reaction force, thereby providing stable support conditions for the detection. By setting up a connecting structure, during the pulling process, the holding assembly can effectively compensate for the slight displacement and angle change that occurs, ensure the relative position between the connecting column and the sleeve is stable, and thus avoid pull-out force eccentricity. In addition, by using the clamping assembly in conjunction with the fixing assembly, not only can a firm connection with the spiral anchor during the pulling process be guaranteed, but also the spiral anchor can be prevented from shaking or displacing under the action of the pull-out force, further improving and ensuring the integrity of the entire connecting structure during the pulling process, effectively transmitting the pull-out force, and avoiding the pull-out force detection result being affected by loose connection.

[0007] The present invention is further configured as follows: the retaining assembly includes a rubber ring, the rubber ring is sleeved on the top of the surface of the connecting column, and the inside of the rubber ring is provided with a plurality of arc-shaped top plates in an annular shape, the arc-shaped top plate is in contact with the inner wall of the connecting column on one side close to it, a push plate is provided on one side of the arc-shaped top plate, and an elastic sheet is provided on the side of the push plate close to the inner wall of the rubber ring, the bottom of the rubber ring is connected to a connecting pipe, and the bottom of the connecting pipe is connected to a sleeve, the inside of the sleeve is slidably connected with a contact plate, the side of the contact plate close to the connecting column and the inner wall of the sleeve is respectively connected to the two, and a pressure spring is provided between the opposite sides of the two contact plates.

[0008] By adopting the above technical solution, by setting up a retaining component, the axial position of the connecting column can be maintained by the rubber ring.

The pressure of the internal compressed air can make the rubber ring adapt to its position change within a certain range, and through the connecting pipe, the compressed air can flow freely in the rubber ring and the sleeve, so that the compressed air can change with the pressure, so that the contact plate can adaptively maintain the corresponding position of the connecting column under the coordinated cooperation of the pressure spring and the compressed air, and can automatically adapt and adjust during the pulling process to ensure that the position of the connecting column in the sleeve is stable, thereby maintaining the coaxiality of the pulling direction and the axis of the spiral anchor.

[0009] The present invention is further configured as follows: a plurality of slots are provided inside the rubber ring, the push plate and the elastic sheet are both arranged inside the slots, and the slots, the connecting pipe and the sleeve are all filled with compressed air.

[0010] By adopting the above technical solution, by setting the groove, when the pulling force or external factors cause the position of the connecting column to change, the spatial change of the groove in the rubber ring will affect the pressure of the compressed air, and the compressed air transmits the pressure in the sleeve through the connecting pipe, so that the contact plate adjusts the pressure on the connecting column and the inner wall of the sleeve under the synergistic action of the pressure spring to maintain the balance and stability of the entire retaining assembly.

[0011] The present invention is further configured as follows: the fixing assembly includes a screw rod, which is rotatably connected to the inside of a connecting column, and a threaded sleeve is threadedly connected to the bottom of the screw rod surface, the surface of the threaded sleeve is rotatably connected to a plurality of connecting rods in a ring shape, and the other end of the connecting rod is rotatably connected to a movable plate, a fixing column is provided on a side of the movable plate close to the clamping assembly, and a side of the fixing column close to the clamping assembly contacts an inner wall thereof, a side of the movable plate close to the connecting column is rotatably connected to a connecting frame, and a side of the connecting frame close to the connecting column is connected to it.

[0012] By adopting the above technical solution and setting up a fixing component, the screw can be rotated, and the screw sleeve can move downward under the action of the thread by utilizing the cooperation between the screw and the thread of the screw sleeve. At the same time, the movement of the screw sleeve drives the movable plate to move through the connecting rod, so that the movable plate rotates with the connecting frame as the fulcrum, so that the fixed column on the movable plate adjusts its position accordingly, and the fixed column enters the interior of the clamping component, thereby realizing the connection between the connecting column and the clamping component, which is convenient for the transmission of the pulling force.

[0013] The present invention is further configured as follows: a movable hole is provided in a ring shape on the surface of the connecting column, and one side of the connecting rod passes through the interior of the movable hole.

[0015] The present invention is further configured as follows: the clamping assembly includes a centering sleeve, the top of the centering sleeve is in contact with a connecting plate, and the connecting plate is connected to a fixed column, the bottom of the connecting plate is connected to a plurality of clamping blocks via a steel cable, and the side of the clamping block close to the inner wall of the centering sleeve is in sliding contact with it, the bottom of the centering sleeve is bolted with a fixing ring, and the interior of the fixing ring is annularly threaded with a plurality of centering bolts.

[0016] By adopting the above technical solution, through setting up the clamping assembly, the centering sleeve and the spiral anchor can be kept on the same axis through the centering bolt, and during the pulling process, the connecting plate will be driven to move under the influence of the tension, and the clamping block will be driven to slide along the inner wall of the centering sleeve simultaneously, and the inclined surfaces of the two are used to make the clamping block gradually approach the surface of the spiral anchor, and under the action of the tension, the clamping block clamps the spiral anchor, thereby achieving fixation with the spiral anchor.

[0019] The present invention is further configured as follows: the opposite sides of the centering sleeve and the clamping block are both arranged in an inclined surface, and the opposite sides of two adjacent clamping blocks are both arranged with groove patterns.

[0020] By adopting the above technical solution, the centering sleeve and the opposite side of the clamping block are arranged in an inclined surface, so that during the pulling process, as the pulling force increases, the clamping force of the clamping block on the spiral anchor will gradually increase, thereby ensuring a firm connection. By setting the groove texture on the surface of the clamping block, the friction between the clamping block and the spiral anchor can be further increased, preventing the spiral anchor from slipping during the pulling process.

[0022] By adopting the above technical solution, by setting up an anchoring assembly, the impact of the force on the reaction base can be reduced by the coordinated use of a rubber pad and a supporting spring, and by the fixed tube penetrating deep into the soil and utilizing the contact between the elastic member and the soil, the contact area between the fixed tube and the soil can be expanded, thereby improving the stability of the reaction base, and as the pulling force increases, the reaction force also gradually increases, so that the push column penetrates deep into the interior of the fixed tube and drives the extrusion ring to move, so that the extrusion ring squeezes the elastic member, so that several elastic members can gradually expand, thereby further increasing the contact area with the soil, and further improving the stability of the reaction base, which not only ensures the stability during the detection process, but also reduces the impact on the coaxiality during the detection process.

[0023] The present invention is further configured as follows: a connecting block is provided in an annular shape at the bottom of the surface of the push column, and a side of the connecting block close to the extrusion ring is connected to the extrusion ring.

[0024] By adopting the above technical solution, the connection between the extrusion ring and the pushing column can be achieved by setting a connecting block, so that it is convenient for the pushing column to drive the extrusion ring to move.

A clamping component 63 is provided at the bottom of the connecting column 61, and a fixing component 64 is provided inside the connecting column 61, and the side of the fixing component 64 close to the clamping component 63 is connected to it. By setting the connecting structure 6, the retaining component 62 can effectively compensate for the slight displacement and angle change that occur during the pulling process, ensure the relative position between the connecting column 61 and the sleeve 4 is stable, thereby avoiding eccentricity of the pulling force, and through the coordinated use of the clamping component 63 and the fixing component 64, not only can a firm connection with the spiral anchor be guaranteed during the pulling process, but also the spiral anchor can be prevented from shaking or displacing under the action of the pulling force, further improving and ensuring the integrity of the entire connecting structure 6 during the pulling process, effectively transmitting the pulling force, and avoiding the influence of the pulling force detection result due to loose connection.

[0030] The retaining assembly 62 includes a rubber ring 621, which is sleeved on the top of the surface of the connecting column 61, and a plurality of arc-shaped top plates 622 are arranged in an annular shape inside the rubber ring 621, and the arc-shaped top plates 622 are in contact with the inner wall of the connecting column 61 on one side thereof, and a push plate 623 is arranged on one side of the arc-shaped top plate 622, and an elastic sheet 624 is arranged on the side of the push plate 623 close to the inner wall of the rubber ring 621, and a connecting tube 625 is connected to the bottom of the rubber ring 621, and a sleeve 626 is connected to the bottom of the connecting tube 625, and a contact plate 627 is slidably connected to the inside of the sleeve 626, and the contact plate 627 is connected to the connecting column 61 and the inner wall of the sleeve 4 on one side thereof, respectively, and a pressure spring 628 is arranged between the opposite sides of the two contact plates 627, and the retaining assembly is arranged 62, the axial position of the connecting column 61 can be maintained by the rubber ring 621. When the connecting column 61 is subjected to a large external force, the arc-shaped top plate 622 moves with the connecting column 61, and moves and squeezes the elastic sheet 624 through the push plate 623. The pressure of the internal compressed air can make the rubber ring 621 adapt to its position change within a certain range, and through the connecting pipe 625, the compressed air can flow freely in the rubber ring 621 and the sleeve 626, so that the compressed air can change with the pressure, so that the contact plate 627 can adaptively maintain the corresponding position of the connecting column 61 under the coordinated cooperation of the pressure spring 628 and the compressed air, and can automatically adapt and adjust during the pulling process, ensuring that the position of the connecting column 61 in the sleeve 4 is stable, thereby maintaining the coaxiality of the pulling direction and the axis of the spiral anchor.

[0031] Among them, a plurality of slots are opened inside the rubber ring 621, and the push plate 623 and the elastic sheet 624 are both arranged inside the slots, and the slots, the connecting tube 625 and the sleeve 626 are all filled with compressed air. By setting the slots, when the pulling force or external factors cause the position of the connecting column 61 to change, the spatial change of the slots in the rubber ring 621 will affect the pressure of the compressed air, and the compressed air transmits the pressure in the sleeve 626 through the connecting tube 625, so that the contact plate 627 adjusts the pressure on the connecting column 61 and the inner wall of the sleeve 4 under the coordinated action of the pressure spring 628, so as to maintain the balance and stability of the entire retaining assembly 62.

[0032] The fixing assembly 64 includes a screw rod 641, which is rotatably connected to the inside of the connecting column 61, and a screw sleeve 642 is threadedly connected to the bottom of the surface of the screw rod 641, and the surface of the screw sleeve 642 is rotatably connected to a plurality of connecting rods 643 in an annular manner, and the other end of the connecting rod 643 is rotatably connected to a movable plate 644, and a fixing column 645 is provided on the side of the movable plate 644 close to the clamping assembly 63, and the side of the fixing column 645 close to the clamping assembly 63 is in contact with the inner wall thereof, and a connecting frame 646 is rotatably connected to the side of the movable plate 644 close to the connecting column 61, and the connecting frame 646 is close to the inner wall of the clamping assembly 63, and the fixing column 645 ... One side near the connecting column 61 is connected to it, and a fixing assembly 64 is set up. By rotating the screw rod 641, the screw sleeve 642 will move downward under the action of the thread by utilizing the thread cooperation between the screw rod 641 and the screw sleeve 642. At the same time, the movement of the screw sleeve 642 drives the movable plate 644 to move through the connecting rod 643, so that the movable plate 644 rotates with the connecting frame 646 as the fulcrum, so that the fixing column 645 on the movable plate 644 adjusts its position accordingly, and the fixing column 645 enters the interior of the clamping assembly 63, thereby realizing the connection between the connecting column 61 and the clamping assembly 63, which is convenient for the transmission of the pulling force.

[0033] Among them, the surface of the connecting column 61 is provided with a circular movable hole, and one side of the connecting rod 643 passes through the inside of the movable hole. By setting the movable hole, the connecting rod 643 can pass through the connecting column 61 to connect with the movable plate 644, thereby facilitating the adjustment of the position of the movable plate 644.

[0034] Among them, the clamping assembly 63 includes a centering sleeve 631, the top of the centering sleeve 631 contacts with a connecting disk 632, and the connecting disk 632 is connected to the fixing column 645, the bottom of the connecting disk 632 is connected with a plurality of clamping blocks 633 through a steel cable, and the clamping block 633 is in sliding contact with the side close to the inner wall of the centering sleeve 631, the bottom of the centering sleeve 631 is bolted with a fixing ring 634, and the interior of the fixing ring 634 is annularly threaded with a plurality of centering bolts 635. By setting the clamping assembly 63, the centering sleeve 631 and the spiral anchor can be kept at the same axis through the centering bolts 635, and during the pulling process, the connecting disk 632 will be driven to move under the influence of the pulling force, and the clamping block 633 will be driven to slide along the inner wall of the centering sleeve 631 simultaneously, and the inclined surfaces of the two will be used to make the clamping block 633 gradually approach the surface of the spiral anchor, and under the action of the pulling force, the clamping block 633 will clamp the spiral anchor, thereby achieving fixation with the spiral anchor.

[0035] Among them, a plug-in column 7 is provided at the bottom of the connecting column 61, and a slot for use with the plug-in column 7 is opened at the top of the connecting plate 632. The connecting column 61 is connected to the connecting plate 632 through the plug-in column 7 and the slot. By setting the plug-in column 7 and the slot, the connection between the connecting column 61 and the connecting plate 632 can be achieved, thereby facilitating the pull-out test of the spiral anchor.

[0036] Among them, the opposite sides of the centering sleeve 631 and the clamping block 633 are both inclined, and the opposite sides of two adjacent clamping blocks 633 are both provided with groove patterns. By setting the opposite sides of the centering sleeve 631 and the clamping block 633 to be inclined, during the pulling process, as the pulling force increases, the clamping force of the clamping block 633 on the spiral anchor will gradually increase, ensuring a firm connection. By setting the groove patterns on the surface of the clamping block 633, the friction between the spiral anchor and the spiral anchor can be further increased to prevent the spiral anchor from slipping during the pulling process.

[0037] The working principle of this embodiment is as follows: the centering sleeve 631 and the spiral anchor are kept at the same axis by the centering bolt 635, and then the plug column 7 is inserted into the slot to limit the position of the connecting column 61, and then the screw rod 641 is rotated, and the screw sleeve 642 moves downward under the action of the thread by utilizing the thread cooperation between the screw rod 641 and the screw sleeve 642. At the same time, the movement of the screw sleeve 642 drives the movable plate 644 to move through the connecting rod 643, so that the movable plate 644 rotates with the connecting frame 646 as the fulcrum, thereby making the movable plate 64 The fixed column 645 on the 4 is adjusted to the position accordingly, so that the fixed column 645 enters the interior of the connecting plate 632, and then the sleeve 4 is put on the surface of the connecting column 61, and the retaining assembly 62 is in contact with its inner wall, and then the sleeve 4 is connected to the connecting plate 5 and the jacking rod 3 at the same time, and then the jacking rod 3 is moved by extending the hydraulic cylinder 2. During the pulling process, the connecting plate 632 is driven to move under the influence of the pulling force, and the clamping block 633 is driven to slide along the inner wall of the centering sleeve 631 at the same time, and the two are used to The inclined surface makes the clamping block 633 gradually approach the surface of the spiral anchor. As the pulling force increases, the clamping force of the clamping block 633 on the spiral anchor will gradually increase, so that the clamping block 633 is in close contact with the spiral anchor. When the connecting column 61 is subjected to a large external force, the arc-shaped top plate 622 moves with the connecting column 61, and moves and squeezes the elastic sheet 624 through the push plate 623. Through the pressure of the internal compressed air, the rubber ring 621 can adapt to its position change within a certain range, and through the connecting pipe 625, the compressed air can flow freely in the rubber ring 621 and the sleeve 626, so that the compressed air can change with the pressure, so that the contact plate 627 can adapt to the corresponding position of the connecting column 61 under the coordinated cooperation of the pressure spring 628 and the compressed air, and can automatically adapt and adjust during the pulling process to ensure that the position of the connecting column 61 in the sleeve 4 is stable, thereby maintaining the coaxiality of the pulling direction and the axis of the spiral anchor. Finally, the spiral anchor is destroyed and the pulling force reaches the design requirement, that is, the detection of the pulling force of the spiral anchor is completed.

[0038] Example 2 refer to Figure 1 and Figure 7A pull-out force detection device for a substation prefabricated cabin spiral anchor design also includes a reaction base 1, wherein the reaction base 1 includes an upper base 11 and a lower base 12, and the four corners inside the lower base 12 are penetrated by anchor components 13, and the top of the anchor component 13 is connected to the upper base 11, and the upper base 11 is connected to the hydraulic cylinder 2. By setting the reaction base 1, during the pull-out force detection of the spiral anchor, especially in the soft surface soil environment, the upper base 11 and the lower base 12 are connected through the anchor component 13, and the anchor component 13 can penetrate into the soil and maintain good friction between the soil, so that the reaction base 1 can adapt to the unevenness of the soft ground, buffer and disperse the reaction force generated by the pull-out force, and prevent the base from sinking into the ground or uncontrollable movement due to the reaction force, thereby providing stable support conditions for detection.

[0039] The anchor assembly 13 includes a fixing tube 131, which passes through the interior of the lower base 12, and an elastic member 132 is provided at the bottom of the surface of the fixing tube 131 in a ring shape, and a pushing column 133 is provided inside the fixing tube 131 for sliding, and a rubber pad 134 is sleeved on the top of the pushing column 133 and the surface of the fixing tube 131, and the rubber pad 134 is connected to the upper base 11 and the lower base 12 on one side thereof, respectively, and a supporting spring 135 is provided between the opposite sides of the two rubber pads 134, and an extrusion ring 136 is sleeved on the surface of the fixing tube 131, and the extrusion ring 136 is connected to the pushing column 133. By providing the anchor assembly 13, the rubber pad 134 and the supporting spring 135 can be connected to each other. The coordinated use can reduce the impact of the force on the reaction base 1, and the fixed tube 131 penetrates into the soil, and the contact area between the fixed tube 131 and the soil is expanded by utilizing the contact between the elastic member 132 and the soil, thereby improving the stability of the reaction base 1, and as the pulling force increases, the reaction force also gradually increases, so that the pushing column 133 penetrates into the interior of the fixed tube 131 and drives the extrusion ring 136 to move, so that the extrusion ring 136 squeezes the elastic member 132, so that several elastic members 132 can be gradually expanded, thereby further increasing the contact area with the soil, and further improving the stability of the reaction base 1, which not only ensures the stability during the detection process, but also reduces the impact on the coaxiality during the detection process.

[0040] Among them, a connecting block 8 is arranged in a ring shape at the bottom of the surface of the pushing column 133, and the connecting block 8 is connected to the side close to the extrusion ring 136. By setting the connecting block 8, the connection between the extrusion ring 136 and the pushing column 133 can be realized, so that it is convenient for the pushing column 133 to drive the extrusion ring 136 to move.

[0041] The working principle of this embodiment is as follows: by penetrating the fixed tube 131 into the soil and utilizing the contact between the elastic member 132 and the soil, the contact area between the fixed tube 131 and the soil can be expanded, thereby improving the stability of the reaction base 1, and as the pulling force increases, the reaction force also gradually increases, so that the push column 133 penetrates into the interior of the fixed tube 131 and drives the extrusion ring 136 to move, so that the extrusion ring 136 squeezes the elastic member 132, so that several elastic members 132 can be gradually expanded, thereby further increasing the contact area with the soil, further improving the stability of the reaction base 1, and the coordinated use of the rubber pad 134 and the support spring 135 can reduce the impact of the force on the reaction base 1.
