DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example 1: Reference Figure 1-Figure 14 A prefabricated ancient building support structure stability detection device comprises: a base 1, a mounting tube 2, a pressure mechanism 3, a connecting mechanism 4 and a top plate 5. A mounting tube 2 is provided in the middle of the top surface of the base 1, and a lifting mechanism is connected inside the mounting tube 2. The top surface of the base 1 is connected with a pressure mechanism 3, a connecting mechanism 4 and a measuring mechanism 6. The ends of the pressure mechanism 3 and the measuring mechanism 6 are in contact and fit. The measuring mechanism 6 is arranged above the mounting tube 2. A top plate 5 is installed on the connecting mechanism 4, and the top plate 5 is arranged above the measuring mechanism 6.

[0035] The principles and beneficial effects of the above scheme are:

[0036] Before starting the test, place the support column in the installation tube 2, and make the top end of the lifting mechanism contact and cooperate with the bottom end of the support column, move the ends of the pressure mechanism 3 and the measuring mechanism 6, make the ends of the two contact and cooperate, and at the same time contact the side wall of the support column, then fix the connecting mechanism 4 on the top surface of the base 1, and make the bottom surface of the top plate 5 contact and cooperate with the top end of the support column. When measuring, start the pressure mechanism 3 to apply pressure to the side of the support column, and the measuring mechanism 6 will display the deformation of the support column. When the pressure is applied to the side of the support column, the stability of the support column before installation can be measured. When the lifting device is started, and the lifting device and the top plate 5 apply longitudinal pressure to the support column, it can also simulate the stress that the support column will bear after installation. The pressure can be measured and displayed to show the stability of the support column after installation. The pressure mechanism 3 and the measuring mechanism 6 can measure the stability of the structure of the support column before installation. At the same time, the cooperation between the lifting mechanism and the top plate 5 can simulate the actual pressure state of the support column when bearing weight after installation. Therefore, the device can further test the stability of the support column after installation, thereby improving the comprehensiveness of the stability detection and further ensuring the safety of the support column after it is put into use. Compared with the prior art, when it is necessary to simulate the burial depth of the support column, it is only necessary to adjust the distance between the top surface of the lifting mechanism and the top of the installation pipe 2. At the same time, when it is necessary to simulate the formation pressure, it is only necessary to select the installation pipe 2 with an appropriate inner diameter to cooperate with the support column set. Therefore, the technical solution adopted in this application is more practical.

[0037] Example 2: Reference Figure 1-Figure 14 The connecting mechanism 4 includes: a mounting tube 27, a bolt 8 and a connecting column 9. The bottom ends of multiple mounting tubes 27 are fixed to the top surface of the base 1. The bottom ends of the connecting columns 9 are inserted into the mounting tube 27. The bolts 8 are threadedly connected to the screw holes on the side walls of the mounting tube 27. The screw holes are opened on the side walls of the mounting tube 27. The ends of the bolts 8 are threadedly connected to the fixing screw holes on the side walls of the connecting columns 9. The top ends of the connecting columns 9 are connected to the bottom surface of the top plate 5.

[0038] The principles and beneficial effects of the above scheme are:

[0039] After the connecting column 9 is inserted into the mounting tube 7, the bolt 8 is rotated to make it threadedly connected with the screw hole and the fixing screw hole respectively, thereby completing the fixation of the connecting column 9 and then completing the fixation of the top plate 5. When the lifting mechanism is started, it cooperates with the top plate 5 to apply pressure to the bottom end of the support column. The bolt 8 fixes the connecting column 9 to improve the stability of the device during detection.

[0040] Example 3: Reference Figure 1-Figure 14 The top surface of the top plate 5 is provided with a plurality of hooks 10 .

[0041] The principles and beneficial effects of the above scheme are:

[0042] After the support column is placed in the installation pipe 2, the lifting equipment is started, and the lifting hook 10 is lifted by the lifting ring of the lifting equipment, and then the top plate 5 is lifted. By arranging the lifting hook 10 on the top plate 5, it is convenient to move the top plate 5.

[0043] Example 4: Reference Figure 1-Figure 14 The bottom end of the mounting tube 2 is placed in the mounting cavity 11 of the base 1, and the bottom end of the motor is slidably connected to the middle of the bottom wall of the mounting cavity 11. The bottom end of the worm 12 is installed at the output end of the motor, and the top of the worm 12 is installed with a gear 13. The gear 13 is arranged below the bottom end of the mounting tube 2. The end of a pull rod 14 is installed on the side of the motor. The pull rod 14 is slidably connected to the circular hole on the side wall of the base 1, and the end of the pull rod 14 that passes through the outside of the base 1 is connected with a pull ring 15.

[0044] The principles and beneficial effects of the above scheme are:

[0045] The pull ring 15 is pulled to drive the pull rod 14 to move, and the pull rod 14 drives the motor to move, so that the worm 12 and the gear 13 can move in the installation cavity 11.

[0046] Example 5: Reference Figure 1-Figure 14 The lifting mechanism includes: a lifting plate 16, a lifting plate 16 is slidably connected in the mounting tube 2, the bottom surface of the lifting plate 16 is rotatably connected with the top of a screw 17, the screw 17 is threadedly connected to the second screw hole, the second screw hole is opened on the sealing plate at the bottom end of the mounting tube 2, the bottom end of the screw 17 is provided with a spline shaft slot, the spline shaft slot is slidably connected to the spline at the top of the spline shaft 18, the bottom end of the spline shaft 18 is rotatably connected to the bottom wall of the mounting cavity 11, and a gear 2 19 is coaxially installed on the spline shaft 18, the gear 2 19 is arranged below the sealing plate, the top surface of the gear 2 19 is coplanar with the top surface of the gear 13, and the gear 2 19 is adjacent to the gear 13.

[0047] The principles and beneficial effects of the above scheme are:

[0048] After the bottom end of the support column is placed in the installation tube 2, the top end of the support column contacts and cooperates with the bottom surface of the top plate 5. When the longitudinal pressure on the support column after installation needs to be simulated, the pull ring 15 is pulled outward to finally make the gear 13 and the gear 2 19 mesh with each other, start the motor, the motor output end rotates clockwise, the worm 12 and the gear 13 rotate synchronously clockwise, the gear 13 drives the gear 2 19 meshing with it to rotate counterclockwise, the spline shaft 18 rotates counterclockwise, the screw 17 rotates counterclockwise, and the screw 17 is threadedly connected to the screw hole 2. At the same time, the top end of the screw 17 is turned to The top end of the mounting tube 2 moves in the direction of the spline shaft slot and the spline at the top of the spline shaft 18 are slidably connected, so the spline shaft 18 can provide guidance for the upward movement of the screw 17. The lifting plate 16 moves upward synchronously with the upward movement of the screw 17. Since the lifting plate 16 is rotationally connected to the top end of the screw 17, when the lifting plate 16 rises, it will not rub against the bottom end of the support column, which can prevent the bottom end of the support column from being damaged. At the same time, it can prevent the bending position of the support column from changing after the longitudinal pressure and the lateral pressure are applied, thereby avoiding the mechanism from repeatedly rotating the support column during measurement.

[0049] Example 6: Reference Figure 1-Figure 14 One end of a rotating shaft 20 is rotatably connected to each of the two inner walls of the installation cavity 11. Two worm segments 21 are provided on the rotating shaft 20. A worm wheel 22 is coaxially installed in the middle of the rotating shaft 20. The worm wheel 22 is arranged adjacent to the worm 12, and the motor is arranged between the worm wheel 22 and the gear 2 19.

[0050] The principles and beneficial effects of the above scheme are:

[0051] The two ends of the rotating shaft 20 are respectively rotatably connected to an inner wall of the mounting cavity 11, which improves the stability of the rotating shaft 20 during operation. A worm gear 22 is arranged in the middle of the rotating shaft 20, and the motor is arranged between the worm gear 22 and the gear 19. The spacing between the worm gear 22 and the gear 19 can provide sufficient distance for the movement of the motor. The mounting tube 2 is arranged in the middle of the mounting cavity 11, and the motor is slidably connected to the middle of the bottom wall of the mounting cavity 11. Because the worm gear 22 is arranged in the middle of the rotating shaft 20, the movement of the motor facilitates the meshing connection of the gear 13 with the gear 19, or the meshing connection of the worm 12 with the worm wheel 22. When the worm 12 is meshed with the worm wheel 22, it is convenient for the motor to drive the worm wheel 22, and further facilitates the driving of the rotating shaft 20 to rotate.

[0052] Example 7: Reference Figure 1-Figure 14 The pressure mechanism 3 includes: a mounting frame 23, one end of which is threadedly connected to the threaded section of the longitudinal shaft 24, the longitudinal shaft 24 is rotatably connected to the second circular hole on the top surface of the base 1, the bottom end of the longitudinal shaft 24 placed in the mounting cavity 11 is equipped with a worm gear 25, the worm gear 25 is meshedly connected to a worm segment 21, and the other end of the mounting frame 23 is slidably connected to the guide rod 26 on the top surface of the base 1.

[0053] The mounting frame 23 is provided with a mounting cavity 27, in which a cylinder 28 is installed. The output shaft of the cylinder 28 is slidably connected to the circular hole 3 on the side wall of the mounting frame 23. The end of a guide tube 29 is installed on the middle side wall of the mounting frame 23. The end of the output shaft of the cylinder 28 is placed in the guide tube 29 and connected to the end of a push block 30. The push block 30 is slidably connected to the inner wall of the guide tube 29, and the other end of the push block 30 outside the guide tube 29 is provided with a longitudinal groove.

[0054] The principles and beneficial effects of the above scheme are:

[0055] When measuring the stability of the support column, the height of the mounting bracket 23 can be adjusted. The specific method is that after the worm wheel 22 is meshed with the worm 12, the motor is started to rotate forward or reverse. Driven by the worm 12, the worm wheel 22 meshed with it flips or rotates forward. Further, the worm wheel 22 drives the rotating shaft 20 to rotate reversely or forward. The worm segment 21 on the rotating shaft 20 drives the worm wheel 25 meshed with it to rotate forward or reverse. At the same time, the longitudinal shaft 24 rotates forward or reversely. The end of the mounting bracket 23 threadedly connected to the longitudinal shaft 24 rises or falls relative to the longitudinal shaft 24. The guide rod 26 slidably connected to the other end of the mounting bracket 23 provides guidance for the rise or fall of the mounting bracket 23. When the mounting bracket 2 After moving to the designated position, the cylinder 28 is started, and the output shaft of the cylinder 28 is extended to drive the push block 30 to move. The longitudinal groove on the push block 30 contacts and cooperates with the side wall of the support column, increasing the contact area between the push block 30 and the side wall of the support column, preventing the support column from being damaged during the test due to excessive local pressure. At the same time, the extension of the push block 30 applies pressure to the side wall of the support column, which is convenient for simulating the lateral force on the support column. Adjusting the height of the mounting frame 23 also drives the adjustment of the height of the push block 30, which is convenient for further testing of various positions of the support column. After the test is completed, the cylinder 28 is started again, and the output end of the cylinder 28 is retracted to drive the retraction of the push block 30.

[0056] Example 8: Reference Figure 1-Figure 14 The measuring mechanism 6 includes: a mounting frame 31, the mounting frame 31 is threadedly connected to the threaded section of the longitudinal axis 32, the longitudinal axis 32 is rotatably connected to the circular hole 4 on the top surface of the base 1, the bottom end of the longitudinal axis 32 placed in the mounting cavity 11 is equipped with a worm gear 3, the worm gear 3 is meshed and connected with another worm segment 21, the other end of the mounting frame 31 is slidably connected to the guide rod 2 on the top surface of the base 1, the middle part of the mounting frame 31 is equipped with the end of the guide tube 33, the guide tube 33 is slidably connected with a push block 34, one end of the push block 34 is connected to the inner wall of the guide tube 33 through a spring 35, the other end of the push block 34 is placed outside the guide tube 33 and has a longitudinal groove 2, the other end face of the push block 34 is in contact with the other end face of the push block 30.

[0057] The side wall of the push block 2 34 is provided with a wire 56, and the wire 56 is electrically connected to a power source. One end of the wire 56 is slidably connected to a resistor 57, and the resistor 57 is installed on the inner wall of the guide tube 2 33. The resistor 57 is electrically connected to one end of the wire 2 58, and the other ends of the wire 56 and the wire 2 58 are both electrically connected to an ammeter. The spring 35 is a hollow structure, and the top of the spring 35 is connected to the end of the conduit 36, and the other end of the conduit 36 ​​is placed in the mounting cavity 3 of the mounting frame 2 31 and connected to the top of the liquid storage tank 37. A piston 38 is slidably sealed in the liquid storage tank 37, and hydraulic oil is filled in the top surface of the piston 38, the top surface of the piston 38, the liquid storage tank 37 and the spring 35, and the top of the screw 2 39 is connected to the bottom surface of the piston 38, and the screw 2 39 is threadedly connected to the spiral tube at the bottom of the liquid storage tank 37, and the bottom end of the screw 2 39 is connected to the adjustment mechanism.

[0058] The principles and beneficial effects of the above scheme are:

[0059] When the support column is subjected to lateral pressure, longitudinal pressure, or both pressures, the side of the support column is deformed and bent. Since two worm segments 21 are provided on the rotating shaft 20, and the other worm segment 21 is meshed with the worm gear 3, the rotating shaft 20 rotates to drive the worm gear 3 and the longitudinal shaft 2 32 meshed therewith to rotate. The threaded segment of the longitudinal shaft 2 32 is threadedly connected to one end of the mounting frame 2 31, and the other end of the mounting frame 2 31 is slidably connected to the guide rod 2. The mounting frame 2 31 can rise or fall synchronously with the mounting frame 23. Therefore, when the pressure exerted by the push block 30 on the support column causes the support column to deform, the push block 2 34 can be squeezed by the deformed part of the support column at the same time, or when the lifting plate 16 and the top plate After the support column is deformed by the mutual cooperation of the two support brackets 31 and the two support brackets 34, the height of the mounting frame 31 can be adjusted to be level with the position of the deformed support column, and the push block 34 is squeezed by the deformed part of the support column. After the push block 34 is squeezed, the spring 35 is compressed. At this time, since the end of the wire 56 on the push block 34 and the resistor 57 start to slide from the initial position, the wire 56 is electrically connected to the power supply, the other end of the wire 58 is electrically connected to the ammeter, and the other end of the wire 56 is electrically connected to the ammeter, therefore, the value of the ammeter will change, thereby detecting the stability of the support column; when the device is working, it is easily affected by temperature changes, which will cause the spring 35 to expand or contract, thereby seriously affecting the measurement accuracy. Accuracy, when the ambient temperature becomes higher, the adjustment mechanism drives the screw rod 39 to rotate counterclockwise, the screw rod 39 moves downward in the liquid storage tank 37, the synchronous piston 38 moves downward, part of the hydraulic oil in the spring 35 enters the liquid storage tank 37, and the length of the spring 35 becomes shorter; when the ambient temperature becomes lower, the adjustment mechanism drives the screw rod 39 to rotate clockwise, the screw rod 39 moves upward in the liquid storage tank 37, the synchronous piston 38 moves upward, part of the hydraulic oil in the liquid storage tank 37 enters the spring 35, and the length of the spring 35 becomes longer, ensuring that the length of the spring remains constant before the measurement starts, and at the same time ensuring that the relative positions of the push block 34 and the guide tube 33 are fixed before the measurement, further ensuring that the device is in the lead wire 56 before each measurement starts The ends of the wire 56 are in the same position relative to the resistor 57, that is, at this time, the ends of the wire 56 and the ends of the resistor 57 are in the initial position without contact, which can avoid the distance between the ends of the wire 56 and the ends of the resistor 57 being too large at high temperatures, which makes it impossible to monitor small deformations. It can also prevent the need to increase pressure to monitor current changes, avoid excessive pressure on the support column causing damage to it, or cause harm to on-site equipment and personnel, and avoid the wire 56 end contacting the resistor 57 in advance due to the contraction of the spring 35 at low temperatures, or the resistor 57 area between the wire 56 and the wire 2 58 is too small after pressure is applied, resulting in excessive current on the ammeter and causing damage to the ammeter. The accuracy of monitoring can be guaranteed by adjusting the spring 35;The resistor 57 is arranged on the inner wall of the guide tube 33 to avoid the influence of temperature changes on the resistance value of the resistor 57 itself, further improving the accuracy of monitoring; multiple groups of wires 56, resistors 57 and wires 58 can be arranged in the guide tube 33. The resistor 57 can not only play a role in monitoring, but also be used as a part to assist the sliding of the push block 34. Since the push block 34 and the resistor 57 are in friction with each other, the generation of an oxide film on the surface of the resistor 57 made of certain special metals can be prevented, thereby ensuring the accuracy of monitoring and making full use of the relative movement between parts; the device can also calculate the theoretically tolerable pressure value based on the material and size of the support column. When the support column is not placed in the device, When the pressure mechanism 3 is activated to apply pressure to the measuring mechanism 6, the current value detected by the ammeter under the corresponding pressure is converted to compare it with the theoretically tolerable pressure value. When the current value is about to reach the theoretically tolerable pressure value, the monitoring is terminated to prevent accidents. At the same time, the pressure mechanism 3 can also be used to apply pressure to the measuring mechanism 6 for calibration to detect whether the spring 35 is at the theoretical length. That is, when the current value generated by the actual pressure is zero or less than the theoretical current value, it can be inferred that the piston 38 is in the ascending position and has not descended. When the current value generated by the actual pressure is greater than or reaches the test range of the ammeter, it can be inferred that there is a hydraulic oil leak or that the piston 38 is at the bottom of the liquid storage tank 37. ;

[0061] The pump housing 44 , the air guide pipe 45 , the heat collecting box 46 , the heat preservation box 48 and the air guide pipe 2 49 are filled with nitrogen.

[0062] The air guide pipe 45 is connected to the end of the second air guide pipe 49, the end of the second air guide pipe 49 is arranged between the pump housing 44 and the heat preservation box 48, the other end of the second air guide pipe 49 is connected to the heat preservation box 48, the other end of the second air guide pipe 49 is arranged above the air guide pipe 45, the air guide pipe 45 and the second air guide pipe 49 are connected through a guide pipe 50, a guide column 51 is slidably connected in the guide pipe 50, and the guide column 51 is provided with an air guide hole 52 and a second air guide hole 53, and the air guide hole 52 It is placed above the top wall of the air guide tube 45, and the second air guide hole 53 is set below the other end of the second air guide tube 49. The top of the guide column 51 is connected to the bottom end of the connecting rod 54, and the connecting rod 54 is slidably connected to the positioning hole and the second positioning hole. The positioning hole passes through the top surface of the mounting frame 31, and the second positioning hole passes through the bottom surface of the heat collecting box 46. The top of the connecting rod 54 placed in the heat collecting box 46 is connected to the bottom end of the second spring 55, and the top of the second spring 55 is connected to the top wall of the heat collecting box 46.

[0063] The principles and beneficial effects of the above scheme are:

[0064] When the ambient temperature rises, the heat conducting sheet 47 transfers the absorbed heat to the heat collecting box 46, and absorbs the heat through the spring 2 55 at the same time. After absorbing the heat, the spring 2 55 expands due to the heat and stretches the connecting rod 54 to move downward. The air guide hole 52 on the guide column 51 connects the air guide pipe 45, and the nitrogen enters the heat preservation box 48 from the heat collecting box 46 through the air guide pipe 45. During the flow of nitrogen in the air guide pipe 45, the blade 43 rotates forward to drive the worm 2 42 to rotate forward, and the worm 2 42 drives the worm gear 41 meshing with it to reverse, thereby causing the spline shaft 2 40 and the screw 2 39 to reverse synchronously, and finally driving the piston 38 to rotate high. The temperature drops; when the ambient temperature drops, the heat conducting sheet 47 quickly dissipates heat, and at the same time, the spring 2 55 dissipates the heat. After the heat is dissipated, the spring 2 55 contracts due to the cold, and the connecting rod 54 moves upward. The air guide hole 2 53 on the guide column 51 connects the air guide pipe 2 49, and the nitrogen in the heat preservation box 48 first passes through the air guide pipe 2 49 and then through the air guide pipe 45 to enter the heat collecting box 46. During the flow of nitrogen in the air guide pipe 45, the blade 43 reverses to drive the worm 2 42 to reverse, and the worm 2 42 drives the worm gear 41 meshing therewith to rotate forward, thereby causing the spline shaft 2 40 and the screw 2 39 to rotate forward synchronously, and finally driving the active The height of the plug 38 rises; the arrangement of the above structure realizes the function of self-regulation of the device, and can be completed without relying on electrical equipment and manual participation, which greatly increases the practicality of the device; since the heat collecting box 46 itself is arranged outside the mounting frame 31, and a plurality of heat conducting sheets 47 are installed on the heat collecting box 46, when the temperature changes, the nitrogen inside the heat collecting box 46 is greatly affected by the temperature, and since the heat preservation box 48 is arranged in the third mounting cavity, there is a temperature difference between the heat preservation box 48 and the heat collecting box 46, and the appearance of the temperature difference is more conducive to the flow of nitrogen, so the mechanism has sufficient power to The worm gear 42 is driven to rotate, and finally the height of the piston 38 is adjusted. After the nitrogen is circulated between the insulation box 48 and the heat collecting box 46, the air guide holes 52 and the air guide holes 53 terminate the connection with the air guide pipe 45 or the air guide pipe 45 and the air guide pipe 49. Since the worm gear 41 and the worm gear 42 are mutually locked after the adjustment of the height of the piston 38 is completed, when the same or different pressures are applied to different parts of the support column, the upward or downward movement of the mounting frame 23 and the mounting frame 31 will not cause the hydraulic oil to be injected or discharged from the spring 35, thereby always maintaining the accuracy of monitoring.
