Description

Technical Field

[0001] The invention relates to the field of measurement-related technical fields, and in particular to a steel structure pile foundation inclination detection device. Background Art

[0002] In the construction industry, steel pile foundations are used to improve the supporting strength of the building foundation. Steel pile foundations are also used for support. In engineering supervision, it is often crucial to measure the inclination angle of steel pile foundations. When measuring the inclination angle of steel pile foundations, a steel structure engineering steel pile foundation inclination angle detection device is required.

The device for detecting the inclination angle of a steel structure pile foundation in a steel structure engineering is provided with a thread groove, a fixing rod, a rotating block and a limiting rod. The bottom plate is placed on the ground, and after being placed, the rotating block is rotated to make the fixing rod rotate inside the thread groove. The fixing rod rotates inside the thread groove to make the limiting rod descend. The descending of the limiting rod can make the limiting rod inserted into the ground to fix the bottom plate."

[0031] like Figure 1-4 As shown, the present invention provides an inclination detection device, which is applied to a steel structure pile foundation, and includes a detection rod 1 for detecting the inclination of the steel structure pile foundation, and also includes:

[0032] An upper supporting mechanism 2, arranged at the bottom end of the detection rod 1, for supporting the detection rod 1 on a steel structure pile foundation;

[0033] A lower support mechanism 3 is spaced below the upper support mechanism 2 and is also used to support the detection rod 1 on the steel structure pile foundation;

[0034] The telescopic assembly 4 is telescopically connected between the detection rod 1 and the upper supporting mechanism 2 .

[0035] In the specific implementation, the upper supporting mechanism 2 and the lower supporting mechanism 3 are connected up and down by the telescopic component 4. When the lower supporting mechanism 3 placed at the bottom is fixed on the outer wall of the steel structure pile foundation, the upper supporting mechanism 2 placed at the top is in a released state with respect to the outer wall of the steel structure pile foundation. At this time, the cylinder connected to the bottom of the upper supporting mechanism 2 on the telescopic component 4 is started to push the upper supporting mechanism 2 upward, thereby realizing the length extension of the device on the steel structure pile foundation. Then, when the upper supporting mechanism 2 placed at the top is fixed on the outer wall of the steel structure pile foundation, the lower supporting mechanism 3 placed at the bottom is in a released state with respect to the outer wall of the steel structure pile foundation. At this time, the two cylinders connected to the upper supporting mechanism 2 and the lower supporting mechanism 3 on the telescopic component 4 are started to drive the lower supporting mechanism 3 to move up on the outer wall of the steel structure pile foundation, thereby realizing the movement of the device outside the steel structure pile foundation, and the inclination measurement can be performed at different heights on the steel structure pile foundation without manual lifting, thereby reducing the measurement error.

[0036] It should be noted that the detector installed on the detection rod 1 is composed of a pointer and an angle disk. The tilt condition can be determined by the coordinated use of the pointer on the angle disk.

[0037] In one embodiment, the upper support mechanism 2 and the lower support mechanism 3 have the same structure, and both include a first outer support ring 201 and a second outer support ring 202 that are symmetrical and rotatably connected on one side by a pin shaft, and two arc-shaped clamping blocks 203 for fixing on a steel structure pile foundation are symmetrically arranged on the inner sides of the first outer support ring 201 and the second outer support ring 202, and a rack 2031 is horizontally arranged on the outer end of the arc-shaped clamping block 203, and guide rods 2032 that slide horizontally on the first outer support ring 201 or the second outer support ring 202 are arranged on both sides of the rack 2031 and at the outer end of the arc-shaped clamping block 203. With this design, the first outer support ring 201 and the second outer support ring 202 are rotatably installed through a pin shaft on one side, and the rack 2031 and the arc clamping block 203 welded on the inner end of the guide rod 2032 are slidably installed in the through guide grooves machined on the inner sides of the first outer support ring 201 and the second outer support ring 202. When external force is applied, the two arc clamping blocks 203 installed inside the first outer support ring 201 and the second outer support ring 202 can be synchronously driven to move toward or away from each other, thereby realizing the transition of clamping-release state on the steel structure pile foundation.

[0038] It should be noted that a locking part is installed on the end of the first outer support ring 201 and the second outer support ring 202 away from the pin shaft, and the external threaded fixing rod is rotated and fixed in the internal threaded hole machined on the locking part to achieve the function of fixing and closing the upper support mechanism 2 and the lower support mechanism 3.

[0039] It should be noted that the portion of the guide rod 2032 disposed between the arc-shaped clamping block 203 and the corresponding first outer support ring 201 or the second outer support ring 202 is sleeved with a spring.

[0040] It should be noted that the bottom end of the detection rod 1 is welded to the end surface of the second outer support ring 202 included in the upper support mechanism 2 .

[0041] In one embodiment, the rack 2031 included in the lower support mechanism 3 is extended to the outside and an active component 204 is provided;

[0042] The active component 204 includes a first gear 2041 meshed with the side of the rack 2031, and a second gear 2042 coaxially arranged at the center of the first gear 2041, a transmission shaft is coaxially arranged on the first gear 2041 and the second gear 2042, and a motor 2043 is arranged on the upper end of the transmission shaft. A third gear 2044 is meshed on the side of the second gear 2042 away from the rack 2031, and a first connecting rod 2045 is arranged at the center of the end face of the third gear 2044. In this design, by meshing the first gear 2041 installed on the side extending from the rack 2031 to the outside, and the second gear 2042 installed coaxially on the first gear 2041, when the motor 2043 connected to the coupling on the transmission shaft coaxially installed on the center of the first gear 2041 and the second gear 2042 is started, the first gear 2041 and the second gear 2042 will be driven to rotate, and under the action of the first gear 2041, the rack 2031 meshing on its outside will be driven to move horizontally under the guidance of its corresponding outside, so that the arc-shaped clamping block 203 welded at the inner end of the rack 2031 included in the lower support mechanism 3 can move away from or approach under the guidance of the guide rod 2032; and under the action of the second gear 2042, the third gear 2044 installed on the outside will be meshed and transmitted, and then the first connecting rod 2045 fixed by the groove sleeve on the center of the end face of the third gear 2044 will be driven to rotate.

[0043] In one embodiment, a follower assembly 205 is provided on the rack 2031 included on the upper support mechanism 2 and extends to the outside;

[0044] The follower assembly 205 includes a fourth gear 2051 meshed with the side of the rack 2031, and a first pulley 2052 coaxially arranged at the center of the fourth gear 2051, a transmission belt 2053 is horizontally wound around the first pulley 2052, a second pulley 2054 is wound around the other end of the transmission belt 2053, and a second connecting rod 2055 is arranged on the end face of the second pulley 2054. With such a design, through the second pulley 2054 fixedly sleeved on the end face of the second connecting rod 2055 and the transmission belt 2053 wound around the second pulley 2054, when the second connecting rod 2055 is subjected to the transmitted force, the second pulley 2054 will be driven to rotate, and then through the transmission belt 2053, the first pulley 2052 wound around the transmission belt 2053 is driven to rotate in the same direction. At this time, the fourth gear 2051 coaxially installed with the first pulley 2052 rotates accordingly, and the meshing surface of the fourth gear 2051 outside drives the meshing rack 2031 to move in the horizontal direction, thereby realizing the clamping-release state change of the two arc-shaped clamping blocks 203 installed inside the first outer support ring 201 and the second outer support ring 202 included in the upper support mechanism 2.

[0045] It should be noted that, since the force transmission of the second gear 2042 and the third gear 2044 included in the active component 204 adopts a gear transmission structure, the rotation directions are opposite, while the force transmission of the second pulley 2054 and the first pulley 2052 included in the follower component 205 adopts a belt transmission structure, so that they rotate in the same direction, thereby achieving different clamping-release state changes of the two arc-shaped clamping blocks 203 correspondingly installed in the upper support mechanism 2 and the lower support mechanism 3.

[0046] In one embodiment, a first fixing sleeve 206 slidably mounted on the outer side of the upper end of the first connecting rod 2045 is slidably provided on the outer side of the lower end of the second connecting rod 2055;

[0047] Both ends of the first fixed sleeve 206 are provided with sliding grooves for slidingly inserting the second connecting rod 2055 and the first connecting rod 2045. With this design, the telescopically changeable first fixed sleeve 206 connected by the vertical sliding guide installed between the second connecting rod 2055 and the first connecting rod 2045 not only connects the second connecting rod 2055 and the first connecting rod 2045 to achieve the transmission of the acting force, but also does not interfere with the distance change between the upper supporting mechanism 2 and the lower supporting mechanism 3.

[0048] In one embodiment, the telescopic assembly 4 includes a first telescopic cylinder 41 respectively arranged at the pin connection parts on the first outer support ring 201 and the second outer support ring 202 included on the upper support mechanism 2, and a second telescopic cylinder 42 respectively arranged at the pin connection parts on the first outer support ring 201 and the second outer support ring 202 included on the lower support mechanism 3. With such a design, the first telescopic cylinder 41 and the second telescopic cylinder 42 are bolted to the pin connection parts respectively installed on the upper support mechanism 2 and the lower support mechanism 3, and the ends of the first telescopic cylinder 41 and the second telescopic cylinder 42 are combined in a manner including but not limited to bolting, so as to drive the height change of the upper support mechanism 2 and the lower support mechanism 3 respectively.

[0049] In one embodiment, two groups of support parts, which are composed of two movable rods 5 connected to the adjacent end surfaces of the upper supporting mechanism 2 and the lower supporting mechanism 3 and second fixed sleeves 6 slidably installed on the adjacent ends of the two movable rods 5, are symmetrically arranged between the upper supporting mechanism 2 and the lower supporting mechanism 3. With such a design, when the first telescopic cylinder 41 and the second telescopic cylinder 42 respectively apply external forces to change the height, the two groups of support parts can play a guiding and limiting role, thereby ensuring the movement stability of the overall structure.

[0050] In one embodiment, the active component 204 and the follower component 205 are both provided with L-shaped support plates 7 for horizontally moving the rack 2031. With this design, the L-shaped support plates 7 correspondingly screwed on the active component 204 and the follower component 205 can not only shield and protect the relevant transmission structure, but also provide a guide groove for the lateral movement of the rack 2031, which is convenient for operation as a whole.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
