Description

Technical Field

[0001] The present application relates to the technical field of concrete pouring, and in particular to a pneumatic installation and removal device for a pile foundation concrete pouring conduit. Background Art

[0002] Underwater concrete pouring, also known as conduit concrete, is a method of pouring concrete through a vertical iron pipe, relying on the concrete's own weight. The concrete slowly flows out from the bottom of the conduit and spreads around, so that it will not be disturbed by the water flow outside, thus ensuring the quality. It is suitable for pouring cofferdams, caisson foundations, caisson foundations, underground continuous walls, pile foundations and other underwater or underground projects.

[0003] When pouring pile foundation concrete, a conduit is used. The conduit is formed by splicing multiple sections of pipes. During installation, the two pipes need to be aligned with a wrench and then tightened with a connecting structure. After the pouring is completed, the conduit needs to be moved upward and the connecting structure needs to be removed with a wrench to separate the pipes. When installing and removing the conduit, it is necessary to manually apply force to the wrench to connect or separate two adjacent conduits. However, this installation and removal method requires a lot of strength on the one hand, and on the other hand, the installation and removal time is long and the efficiency is low. In addition, when installing manually by applying force, the tightness of the connection between the two adjacent conduits cannot be guaranteed. Utility Model Content

The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0028] The present application provides a pneumatic installation and removal device for a pile foundation concrete pouring conduit, comprising a wrench, the wrench comprising a wrench body 1 and a wrench handle 2 provided at one end of the wrench body 1, the pneumatic installation and removal device also comprising:

[0029] A load-bearing sleeve 3 disposed below the wrench handle 2 and extending along a first direction, wherein the load-bearing sleeve 3 has an open end;

[0031] When in the first state, the end of the collision unit away from the piston sleeve 4 abuts against the inner wall of the load-bearing sleeve 3, and when in the second state, the collision unit is separated from the inner wall;

[0032] An air intake assembly, one end of which is connected to an end of the piston sleeve 4 relatively away from the inner wall, and is used to inflate the piston sleeve 4 so that the collision unit switches from the second state to the first state; a first through hole 5 is opened on the side wall of the load-bearing sleeve 3, and a second through hole 6 is opened on the side wall of the piston sleeve 4. When the collision unit is in the first state, the first through hole 5 coincides with the second through hole 6 and is connected to the outside to exhaust the air in the piston sleeve 4 so that the collision unit switches from the first state to the second state; when the collision unit is in the second state, the first through hole 5 and the second through hole 6 are staggered.

[0033] Specifically, in this embodiment, the pneumatic installation and removal device of the pile foundation concrete pouring conduit provided in the present application includes a connecting structure, the connecting structure includes a fastening ring, and a first thread arranged inside the fastening ring, and a second thread is arranged on the outer wall of two adjacent conduits, and the two conduits are connected together using the fastening ring, and grooves are evenly arranged on the outside of the fastening ring. It also includes a wrench used in conjunction with the connecting structure, and the wrench includes a wrench body 1 and a wrench handle 2 arranged at one end of the wrench body 1, as shown in FIG. Figure 1As shown, a protrusion is provided on the inner wall of the wrench body 1. When a wrench is needed to connect or remove a catheter, the protrusion on the wrench body 1 is inserted into the groove outside the fastening ring, and the wrench is rotated in one direction, so as to realize the disassembly and installation of the two catheters. The pneumatic installation and disassembly device also includes: a load-bearing sleeve 3 arranged below the wrench handle 2, the load-bearing sleeve 3 extends along a first direction, and an open end is provided at one end of the load-bearing sleeve 3; and also includes a collision component, the collision component includes a piston sleeve 4 extending along the first direction, and an opening is also provided at one end of the piston sleeve 4 away from the open end, and the collision component can be connected through the piston sleeve 4. The piston sleeve 4 enters into the interior of the load-bearing sleeve 3 along the first direction, and the piston sleeve 4 and the load-bearing sleeve 3 jointly form a collision space. The collision assembly also includes a collision unit arranged at one end of the piston sleeve 4 and located in the collision space. The collision unit has a first state and a second state. When the collision unit is in the first state, the end of the collision unit away from the piston sleeve 4 abuts against the inner side wall of the load-bearing sleeve 3 away from the opening end. When the collision unit is in the second state, the end of the collision unit away from the piston sleeve 4 abuts against the inner side wall of the load-bearing sleeve 3 away from the opening end. Also includes an air intake component, one end of the air intake component is connected to an end of the piston sleeve 4 relatively away from the inner wall, the air intake component is used to inflate the piston sleeve 4 to increase the air pressure in the piston sleeve 4. When the air pressure in the piston sleeve 4 gradually increases, it will prompt the collision unit to switch from the second state to the first state. A first through hole 5 is opened on the side wall of the load-bearing sleeve 3, and a second through hole 6 is opened on the side wall of the piston sleeve 4. When the collision unit is in the first state, the first through hole 5 coincides with the second through hole 6 and is connected to the outside to exhaust the air in the piston sleeve 4. When the collision unit is in the second state, the air pressure in the collision space gradually decreases, so that the collision unit can be switched from the first state to the second state. When the collision unit is in the second state, the first through hole 5 and the second through hole 6 are staggered. At this time, the space in the piston sleeve 4 is in a closed state, and the air intake assembly continues to inflate the piston sleeve 4, and so on, so that the collision unit continuously hits the inner wall of the load-bearing sleeve 3, thereby driving the wrench on the load-bearing sleeve 3 to rotate relative to the catheter, so that the fastener will also rotate with the wrench, and the installation and removal of the catheter can be achieved in this way;

[0034] During use, when it is necessary to connect or disassemble the two conduits, the wrench is connected to the connecting structure, and then the piston sleeve is inserted into the bearing sleeve along the first direction, the air intake assembly is opened, and the collision space is inflated. At this time, the pressure in the collision space gradually increases, prompting the collision unit to switch from the second state to the first state. When the collision unit switches to the first state, that is, when one end of the collision unit abuts against the inner wall of the bearing sleeve, the first through hole and the second through hole overlap and are not connected to the outside world, and the pressure in the piston sleeve is reduced. At this time, the collision unit switches from the first state to the second state, and the collision space is continuously inflated through the air intake assembly. The collision unit continuously switches between the first state and the second state, and continuously hits the inner wall of the bearing sleeve. The wrench provided above the bearing sleeve will drive the connection structure to change relative to the conduit, thereby fixing the two conduits or disassembling the two conduits.

[0035] Through the device described in the present application, during installation, the air provided by the air intake assembly is used for impact installation, which solves the problem of insufficient tightness in manual installation and improves the installation efficiency. During the disassembly process, this method can also be used for disassembly, which solves the problem of difficult disassembly, improves the disassembly efficiency, and shortens the disassembly time. At the same time, during disassembly, the vibration of the wrench body will cause the solidified part of the concrete attached to the outer wall of the conduit to split, and then when a high-pressure water gun is used for cleaning later, not only can the viscous or liquid concrete be washed away, but also the solidified part of the concrete can be washed clean.

[0036] Furthermore, the collision unit includes an elastic member 7 connected to one side of the piston sleeve 4 , the elastic member 7 can be extended and retracted along the first direction, and also includes a piston hammer 8 connected to a side of the elastic member 7 away from the piston sleeve 4 .

[0037] Specifically, in this embodiment, if Figure 3 As shown, the collision unit includes an elastic member 7, which is a spring in this embodiment. One end of the elastic member 7 is connected to an inner wall of one side of the piston sleeve 4, and the elastic member 7 can be extended and retracted along the first direction. The collision unit also includes a piston hammer 8 connected to a side of the elastic member 7 away from the piston sleeve 4. When the elastic member 7 is in an original state, the piston hammer 8 is separated from the inner wall of the bearing sleeve 3. When the elastic member 7 is in an extended state, the piston hammer 8 abuts against the inner wall of the bearing sleeve 3.

[0038] When the air intake assembly inflates the piston sleeve 4, the air pressure in the piston sleeve 4 gradually increases, which will cause the elastic member 7 to gradually extend from the original state, thereby pushing the piston hammer 8 to move toward the direction close to the inner wall of the load-bearing sleeve 3 until the piston hammer 8 abuts against the inner wall. At this time, the first through hole 5 overlaps with the second through hole 6 and is connected to the outside, and the air pressure in the piston sleeve 4 will decrease. Therefore, the elastic member 7 will gradually switch from the extended state to the original state. At this time, the piston sleeve 4 returns to the closed space state, and the air intake assembly continues to inflate the piston sleeve 4. This reciprocating process allows the piston hammer 8 to hammer the inner wall of the load-bearing sleeve 3 multiple times.

[0039] Furthermore, the air intake assembly includes an air pump, one end of the air pump is connected to an air pipe 9, the end of the air pipe 9 away from the air pump is connected to an air nozzle 10, an air inlet is opened on the side wall of the piston sleeve 4, and the air nozzle 10 is connected to the piston sleeve 4 through the air inlet.

[0040] Specifically, in this embodiment, if Figure 3 As shown, the air intake assembly includes an air pump, one end of the air pump is connected to an air pipe 9, the end of the air pipe 9 away from the air pump is connected to an air nozzle 10, an air inlet is opened on the piston sleeve 4 and on the side wall of the piston sleeve 4, the air nozzle 10 is connected to the piston sleeve 4 through the air inlet, and so on and so forth, so that the piston hammer 8 can continuously impact the inner wall of the load-bearing sleeve 3.

[0041] Furthermore, a clamping portion 11 is provided on the outer side wall of the piston sleeve 4. When the clamping portion 11 abuts against the opening end and the collision unit is in the first state, the first through hole 5 and the second through hole 6 are connected to the outside.

[0042] Specifically, in the present embodiment, a clamping portion 11 is provided on the outer wall of the piston sleeve 4. The clamping portion 11 may be circumferentially arranged on the outer wall of the piston sleeve 4, or may be evenly spaced on the outer wall of the piston sleeve 4. When the clamping portion 11 abuts against the open end and the collision unit is in the first state, the first through hole 5 overlaps with the second through hole 6 and is connected to the outside. The purpose is to ensure that when the piston hammer 8 abuts against the inner wall, the air pressure in the collision space can be reduced in time to enable the collision unit to reciprocate.

[0043] Furthermore, the pneumatic installation and disassembly device also includes a wrench connecting sleeve 12 arranged above the load-bearing sleeve 3, and the wrench connecting sleeve 12 has an installation space. One end of the wrench handle 2 can enter the installation space and be connected to the wrench connecting sleeve 12. The wrench connecting sleeve 12 extends along a second direction, and the second direction is perpendicular to the first direction.

[0044] Specifically, in this embodiment, the starting and disassembly device also includes a wrench connecting sleeve 12, which is arranged above the load-bearing sleeve 3, and the wrench connecting sleeve 12 extends along a second direction, the second direction is perpendicular to the first direction, and there is an installation space in the wrench connecting sleeve 12, one end of the wrench handle 2 can be extended into the installation space and connected to the wrench connecting sleeve 12.

[0045] Furthermore, the wrench handle 2 includes a connecting column arranged at one end thereof, the shape of the connecting column is adapted to the wrench connecting sleeve 12, the connecting column can be extended into the wrench connecting sleeve 12, and at least two first pin shaft holes arranged along the second direction and extending along the third direction are opened on the connecting column, and a second pin shaft hole is provided on the wrench connecting sleeve 12 at a position corresponding to the first pin shaft hole, the first pin shaft hole and the second pin shaft hole are connected using a pin shaft 13, and the third direction is perpendicular to the second direction and the first direction.

Figure 2 and Figure 4 As shown, a second pin hole corresponding to the position, shape, number and size of the first pin hole is opened on the wrench connecting sleeve 12, and the first pin hole and the second pin hole are connected together using a pin 13, which can enhance the stability of the connection between the connecting column and the wrench connecting sleeve 12.

[0047] Furthermore, a cross handle 14 is provided at one end of the piston sleeve 4 away from the load-bearing sleeve 3 .

[0048] Specifically, in the present embodiment, a cross handle 14 is provided at one end of the piston sleeve 4 away from the load-bearing sleeve 3. When in use, the cross handle 14 is manually held to prevent the piston sleeve 4 from being separated from the load-bearing sleeve 3. At the same time, it can also ensure that under the impact of the piston hammer 8, the load-bearing sleeve 4 drives the wrench and the connecting structure to rotate relative to the catheter.

[0049] Furthermore, a shock-absorbing rubber sleeve 15 is provided on the cross handle 14;

[0050] Furthermore, the material of the shock-absorbing rubber sleeve 15 is rubber.

[0053] Specifically, in this embodiment, a connecting rod 16 is provided between the cross handle 14 and the piston sleeve 4 to further reduce the vibration generated during the collision. At the same time, it can also ensure that the operator will not be injured when the piston sleeve 4 partially withdraws from the load-bearing sleeve 3 during the hand-supporting process.

[0054] Working principle: When it is necessary to connect or disassemble the two catheters, connect the wrench to the connecting structure, then insert the piston sleeve 4 into the bearing sleeve 3 along the first direction, open the air intake assembly, and inflate the piston sleeve 4. At this time, the pressure in the piston sleeve 4 gradually increases, prompting the collision unit to switch from the second state to the first state. When the collision unit switches to the first state, that is, when one end of the collision unit abuts against the inner wall of the bearing sleeve 3, the first through hole 5 coincides with the second through hole 6 and is connected to the outside world, and the pressure in the piston sleeve 4 decreases. At this time, the collision unit switches from the first state to the second state, and continuously inflates the piston sleeve 4 through the air intake assembly. The collision unit continuously switches between the first state and the second state, and continuously hits the inner wall of the bearing sleeve 3.
