DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: A self-locking support rod for construction, such as Figure 1-Figure 3 The cam 3 is connected to the first support shell 1 and the first support shell 1 is connected to the first support shell 1 by sliding. The cam 3 is connected to the first support shell 1 and the first support shell 1 is connected to the first support shell 1 by sliding and sealing. A sealing ring is installed on the outer side of the first sliding plate 3 to increase the sealing effect between the first sliding plate 3 and the first support shell 1. The lower end of the first sliding rod 2 is fixed to the first sliding plate 3. When hydraulic oil is injected into the first support shell 1, the first sliding plate 3 drives the first sliding rod 2 to slide upward along the first support shell 1. The lower end of the first support shell 1 is hinged with a first connecting member 4 through a rotating shaft. The first connecting member 4 is used to be connected to the embedded parts on the raft plate. The first connecting member 4 is connected to the embedded parts of the raft plate by bolts. The first support shell 1 is connected to a fixed pipe 5. The fixed pipe 5 is set to a metal pipe. The first support shell 1 is connected to the fixed pipe 5 by welding. The fixed pipe 5 is located at the lower side of the first sliding plate 3. The fixed pipe 5 is installed with a quick connector. The quick connector is used to increase the connection speed of the fixed pipe 5 and the hydraulic pump oil pipe. The pump has a pressure detection function. The fixed pipe 5 is connected to the oil pipe of the hydraulic pump through a quick connector. The hydraulic pump can control the flow direction of the hydraulic oil inside it. The fixed pipe 5 is installed with a first valve 6. The first valve 6 is used to control the connection state of the fixed pipe 5 and prevent the hydraulic oil in the first support shell 1 from flowing out. The upper end of the first sliding rod 2 is fixedly connected to a first connecting column 7. The upper side of the first connecting column 7 is fixedly connected to a second connecting column 8. The central axes of the first sliding rod 2, the first connecting column 7 and the second connecting column 8 are in the same straight line. The upper side of the second connecting column 8 is hinged with a second connecting member 9. The second connecting member 9 is used to be fixed on the inclined member to be supported. The fixed pipe 5 is installed with a pressure gauge 10. The pressure gauge 10 is used to monitor the pressure value of the hydraulic oil in the first support shell 1 and the fixed pipe 5. The pressure gauge 10 is arranged between the first support shell 1 and the first valve 6. The first connecting member 4 is provided with an angle measuring component. The angle measuring component is used to measure the angle between the first support shell 1 and the first connecting member 4.

[0030] like Figure 3As shown, the angle measuring assembly includes a first fixed base 11, which is fixedly connected to the front side of the first connecting member 4. The first fixed base 11 is slidably connected to a rack 12, and an indicator scale is provided on the front side of the rack 12 away from the first connecting member 4. The scale of the rack 12 is used to indicate the angle between the first support shell 1 and the first connecting member 4. The staff observes the indicator scale of the rack 12 through the window of the first fixed base 11. The first fixed base 11 is provided with a window, which is set as a circular hole. The front end of the rotating shaft between the first support shell 1 and the first connecting member 4 is fixedly connected to a gear 13, which is engaged with the rack 12. The gear 13 is used to drive the rack 12 to move up and down, so that the rack 12 indicates the size of the angle between the first support shell 1 and the first connecting member 4 in real time.

[0031] When using the support rod, the staff first connects the first connecting piece 4 with the embedded parts on the raft plate, and connects the oil pipe on the hydraulic pump to the quick connector of the fixed pipe 5. The hydraulic pump is used to control the flow of hydraulic oil. The staff opens the first valve 6 and then starts the hydraulic pump. The hydraulic oil flows into the first support shell 1 along the fixed pipe 5. After the first sliding plate 3 in the first support shell 1 is squeezed by the hydraulic oil, the first sliding plate 3 drives the first sliding rod 2 fixed thereon to move, and the first sliding rod 2 drives the first connecting column 7 and other parts thereon to move away from the first support shell 1 until the distance between the first connecting piece 4 and the second connecting piece 9 reaches the closing distance. After reaching the appropriate distance, the staff turns off the hydraulic pump and stops injecting hydraulic oil inward. Then the staff controls the first support shell 1 to rotate along the first connecting member 4 to an appropriate angle, and connects the second connecting member 9 to the inclined member on the raft. At this time, the support rod, raft and inclined member form a triangular stable structure. Then the staff starts the hydraulic pump again to extend the distance between the first connecting member 4 and the second connecting member 9 again. The length of the support rod can be changed by the hydraulic pump, thereby changing the placement angle of the inclined member. When the inclination angle of the inclined member is adjusted, the staff closes the first valve 6 and disconnects the oil pipe of the hydraulic pump from the quick connector of the fixed pipe 5.

[0032] As the hydraulic pump gradually injects hydraulic oil into the first supporting shell 1, the inclination angle of the inclined member changes, and the angle between the first supporting shell 1 and the first connecting member 4 also changes synchronously. The first supporting shell 1 drives the rotating shaft between the first supporting shell 1 and the first connecting member 4 to rotate, and the rotating shaft between the first supporting shell 1 and the first connecting member 4 drives the gear 13 thereon to rotate, and the gear 13 drives the rack 12 to rotate, and the rack 12 moves upward along the first fixed seat 11. The staff reads the scale on the rack 12 through the window of the first fixed seat 11, reads the angle between the first supporting shell 1 and the first connecting member 4, and measures the distance between the first connecting member 4 and the second connecting member 9. The angle between the inclined member and the raft plate is calculated by using the trigonometric formula and the computer to complete the adjustment of the angle of the inclined member. Then the staff closes the first valve 6, and then disconnects the oil pipe of the hydraulic pump from the quick connector of the fixed pipe 5.

[0033] In the process of adjusting the angle of the tilting member, the staff first connects the oil pipe of the hydraulic pump with the quick connector of the fixed pipe 5. At this time, the first valve 6 is in the closed state. Then the hydraulic pump is started to inject hydraulic oil into the fixed pipe 5. The hydraulic oil pressure in the fixed pipe 5 gradually increases. When the pressure in the fixed pipe 5 on the right side of the first valve 6 is the same as the pressure indicated by the pressure gauge 10, the staff opens the first valve 6 again. Through the pressure gauge 10, the staff can accurately know the pressure in the fixed pipe 5, avoiding the process of injecting hydraulic oil into the first support shell 1. The hydraulic oil pressure in the fixed pipe 5 on the left and right sides of the first valve 6 is different, resulting in changes in the positions of the first sliding plate 3 and the first sliding rod 2, thereby causing the length of the support rod to change, causing the angle of the tilting member to change, and thus improving the stability of the support rod.

[0034] When the first connecting column 7 and the components thereon need to be moved closer to the first supporting shell 1, the staff discharges the hydraulic oil in the first supporting shell 1 through the hydraulic pump, and the first sliding plate 3 drives the first sliding rod 2 and the first connecting column 7 thereon to move, so that the first connecting column 7 and the components thereon can be moved closer to the first supporting shell 1. If it is necessary to remove this supporting rod, it is only necessary to unfasten the second connecting member 9 from the inclined member, and after resetting this supporting rod, unfasten the first connecting member 4 from the embedded part.

[0035] Example 2: Based on Example 1, Figure 1 、 Figure 4 and Figure 5As shown, it also includes a reinforcement mechanism, which is arranged between the first supporting shell 1 and the first connecting column 7. The reinforcement mechanism is used to improve the connection strength between the first supporting shell 1 and the first connecting column 7. The reinforcement mechanism includes four evenly and symmetrically distributed guide plates 14. The guide plates 14 are provided with circular through holes at equal intervals. The circular through holes on the guide plates 14 are used to reduce the weight of the guide plates 14. The four evenly and symmetrically distributed guide plates 14 are respectively fixed to the left and right sides of the first supporting shell 1. A reinforcement plate 15 is slidably connected between two adjacent guide plates 14. The reinforcement plate 15 is I-shaped and is used to improve the bending resistance of the reinforcement plate 15, so as to prevent the first sliding rod 2 from extending too long and bending due to long-term force, thereby improving the stability of the device. The upper ends of the two evenly distributed reinforcement plates 15 are both fixed to the first connecting column 7. A self-locking component is provided between the reinforcement plate 15 and the first supporting shell 1. The self-locking component is used to stabilize the distance between the first supporting shell 1 and the first connecting column 7.

[0036] like Figure 4 and Figure 5 As shown, the self-locking assembly includes two symmetrically distributed positioning blocks 16, which are symmetrically distributed and connected to the inner sides of adjacent reinforcing plates 15 through rotating shafts. A torsion spring 17 is sleeved on the rotating shaft between the positioning block 16 and the adjacent reinforcing plate 15. The two ends of the torsion spring 17 are respectively fixed to the adjacent reinforcing plate 15 and the adjacent positioning block 16. The torsion spring 17 is used to drive the positioning block 16 to reset. A stopper 18 is fixed to the inner side of the reinforcing plate 15. The stopper 18 is limited and matched with the adjacent positioning block 16. In the initial state, the stopper 18 is squeezed and contacted with the adjacent positioning block 16. Under the limiting action of the stopper 18, the positioning Block 16 can only swing outward. The first supporting shell 1 is fixed with symmetrical and evenly spaced limit blocks 19. The positioning block 16 cooperates with the adjacent limit blocks 19 to limit the adjacent reinforcing plates 15. The reinforcing plates 15 are provided with positioning components. The positioning components are used to control the cooperation state of the positioning block 16 and the adjacent limit blocks 19. The limit blocks 19 are wedge-shaped blocks, which are used to increase the limiting strength of the positioning blocks 16 and the adjacent limit blocks 19, thereby avoiding the increase of the extrusion force between the positioning blocks 16 and the adjacent limit blocks 19, resulting in the failure of the limiting of the positioning blocks 16 and the adjacent limit blocks 19.

[0037] like Figure 4As shown, the positioning component includes a second fixing seat 20, the second fixing seat 20 is fixedly connected to the outer side of the adjacent reinforcing plate 15, the second fixing seat 20 is threadedly connected to a threaded rod 21, one end of the threaded rod 21 is fixedly connected to a hexagonal block, the staff can use a hexagonal wrench to rotate the hexagon on the threaded rod 21, the threaded rod 21 rotates and moves upward along the adjacent second fixing seat 20, the lower end of the threaded rod 21 is fixedly connected to a pull rope 22, the reinforcing plate 15 is fixedly connected to a guide wheel, the pull rope 22 is wound around the adjacent guide wheel, the guide wheel is used to change the pulling direction of the adjacent pull rope 22, in the process of the threaded rod 21 moving upward, the threaded rod 21 drives the adjacent positioning block 16 to swing through the adjacent pull rope 22, and loses cooperation with the adjacent limit block 19, the pull rope 22 is set to a steel wire rope, and the pull rope 22 does not deform under stretching, the pull rope 22 is fixed to the adjacent positioning block 16, and the pull rope 22 is in a taut state in the initial state.

[0038] During the process of the hydraulic pump injecting hydraulic oil into the first support shell 1, the first sliding rod 2 drives the first connecting column 7 and other parts thereon to move. At this time, the first connecting column 7 drives the reinforcing plates 15 on the left and right sides to move upward. The reinforcing plates 15 slide upward along the two adjacent guide plates 14. When this support rod supports the inclined member, the reinforcing plates 15 on both sides improve the connection strength between the first support shell 1 and the first connecting column 7, avoiding the first sliding rod 2 from bending due to long-term force, improving the supporting strength of the support rod, and during the process of the reinforcing plates 15 sliding upward, the first connecting column 7 and the first connecting column 7 are connected. During the process, the pull ropes 22 on both sides are in a tightened state, the positioning block 16 is in contact with the adjacent limit block 19, and the reinforcement plate 15 drives the positioning block 16 thereon to move upward. When the positioning block 16 moves upward, the positioning block 16 contacts the upper limit block 19, and the positioning block 16 is squeezed and swings outward. At this time, the torsion spring 17 is tightened. When the positioning block 16 loses contact with the adjacent limit block 19, the positioning block 16 is reset again under the action of the torsion force of the torsion spring 17 until the reinforcement plate 15 drives the positioning block 16 to move to the specified position.

[0039] In the process of the support rod supporting the inclined member, after long-term use, the sealing performance of the first valve 6 is reduced, resulting in leakage of the hydraulic oil in the first support shell 1. The extrusion force of the inclined member acts on the second connecting member 9, and then the first connecting column 7 and other parts thereon move closer to the first support shell 1. The positioning block 16 is limited by the adjacent limit block 19, so that in the event of hydraulic oil leakage of the first support shell 1, the two positioning blocks 16 cooperate with the adjacent limit blocks 19 to automatically lock the positions of the two reinforcing plates, so that the reinforcing plate 15 supports the first connecting column 7, thereby improving the safety of the support rod. At the same time, the support rod can be repaired in the process of supporting the inclined structure, which is simple and convenient and does not delay the progress of construction.

[0040] When it is necessary to reset the first connecting column 7 and the parts thereon, the staff first uses a wrench to rotate the hexagonal blocks on the upper ends of the threaded rods 21 on both sides, so that the threaded rods 21 move upward along the adjacent second fixed seat 20, and the threaded rods 21 pull the adjacent pull ropes 22 upward. Under the action of the guide wheel, the pull ropes 22 pull the adjacent positioning blocks 16 outward, and the positioning blocks 16 lose coordination with the adjacent limit blocks 19. The staff controls the hydraulic pump to return the hydraulic oil in the first support shell 1 to the hydraulic pump, thereby completing the reset of this support rod. After this support rod is reset, the staff again uses a wrench to rotate the hexagonal blocks on the upper ends of the threaded rods 21 to reset the threaded rods 21 on both sides, so that the pull ropes 22 on both sides are in a taut state again.

[0041] Example 3: Based on Example 2, Figure 6 As shown, it also includes an auxiliary supporting mechanism, which is arranged between the second connecting column 8 and the first supporting shell 1, and the auxiliary supporting mechanism is used to locate the distance between the first connecting column 7 and the first supporting shell 1, and the auxiliary supporting mechanism includes a second sliding plate 24, and a cavity 23 is provided on the lower side of the second connecting column 8, and the cavity 23 is filled with hydraulic oil. The second sliding plate 24 slides and is sealed in the cavity 23, and a sealing ring is provided on the outer side of the second sliding plate 24 to improve the sealing effect between the second sliding plate 24 and the second connecting column 8, and an elastic member 25 is provided in the cavity 23, and the elastic member 25 is set as a spring. The elastic member 25 is initially in a compressed state, and the two ends of the elastic member 25 are respectively fixed to the first connecting column 7 and the second sliding plate 24, and the outer walls of the first connecting column 7 and the second connecting column 8 are fixed with two symmetrical second supporting shells 26, and a third sliding plate 27 is slid and sealed in the second supporting shell 26. A sealing ring is provided on the outer side of the third sliding plate 27 to increase the sealing effect between the third sliding plate 27 and the adjacent second support The sealing effect between the support shells 26 is improved. The second support shell 26 is slidably connected to the second sliding rod 28. The second sliding rod 28 is set to an alloy material to improve the bearing capacity of the second sliding rod 28. The lower end of the second sliding rod 28 is fixed to the first support shell 1, and the upper end of the second sliding rod 28 is fixed to the adjacent third sliding plate 27. When the second support shell 26 moves upward with the first connecting column 7 and the second connecting column 8, hydraulic oil enters the second support shell 26. The second connecting column 8 is fixed with two symmetrical first connecting pipes 29. A one-way valve is installed in the first connecting pipe 29. The first connecting pipe 29 is connected to the cavity 23 and the adjacent second support shell 26. Under the action of the one-way valve, hydraulic oil can only flow from the cavity 23 to the second support shell 26. The second connecting column 8 is fixed with two symmetrical second connecting pipes 30. The second connecting pipe 30 is connected to the cavity 23 and the adjacent second support shell 26. The second connecting pipe 30 is installed with a second valve 31. In the initial state, the two second valves 31 are both in the closed state.

[0042] The staff controls the hydraulic pump to inject hydraulic oil into the first support shell 1, and the first sliding rod 2 drives the first connecting column 7 and other parts thereon to move upward. The first connecting column 7 and the second connecting column 8 drive the second support shells 26 on both sides to move upward. In the initial state, the elastic member 25 is in a compressed state, and the second valves 31 on both sides are in a closed state. The two second support shells 26 move upward, and the hydraulic oil in the cavity 23 flows into the two second support shells 26 along the two first connecting pipes 29. The hydraulic oil passes through the one-way valve of the first connecting pipe 29, and at the same time, the elastic member 25 is in a compressed state. Under the action of the elastic force of 25, the second sliding plate 24 slides upward along the cavity 23. When the support column reaches the specified length, the first connecting column 7, the second connecting column 8 and the second support shell 26 stop moving upward. At this time, the two second support shells 26 are filled with hydraulic oil. When the hydraulic oil in the first support shell 1 leaks, under the action of the one-way valve in the first connecting pipe 29, the hydraulic oil in the second support shell 26 cannot flow back into the cavity 23 along the first connecting pipe 29. At this time, the two second sliding rods 28 support the inclined member, thereby improving the safety of the support rod.

[0043] When it is necessary to reset the support rod, the staff opens the second valves 31 on both sides, and the staff controls the hydraulic pump to discharge the hydraulic oil in the first support shell 1. The first connecting column 7 and the second connecting column 8 drive the two second support shells 26 to move downward, and the third sliding plate 27 squeezes the hydraulic oil in the adjacent second support shells 26. The hydraulic oil in the second support shell 26 flows back to the cavity 23 along the adjacent second connecting pipe 30. The hydraulic oil in the cavity 23 squeezes the second sliding plate 24 downward again, and the second sliding plate 24 slides downward along the cavity 23. The elastic member 25 is compressed again to complete the reset.

[0044] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures and devices not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
