Description

Technical Field

[0001] The invention belongs to the technical field of engineering construction, and in particular is an information data collection device for quota determination. Background Art

[0002] At present, the determination of construction quotas for building construction projects is mainly carried out by professional quota personnel through traditional manual recording to collect on-site data, and perform data analysis based on the on-site recorded data to obtain the quota consumption results, and comprehensively analyze to determine the construction quota and material consumption. For example, when building a house, a stable foundation is often required to support the weight of the house. Therefore, we need to measure the depth of the foundation pile hole in order to calculate the total amount of concrete that needs to be injected into the foundation pile hole. This is a tedious task that is time-consuming, labor-intensive and prone to errors.

[0003] At present, when measuring the depth of the pile hole, people often use a handheld laser rangefinder to measure the depth of the pile hole by the operator, with the laser head perpendicular to the top of the pile hole. However, due to people's own reasons, it is impossible to accurately keep the laser head perpendicular to the pile hole, which causes the laser beam to deviate and fail to irradiate the bottom of the pile hole, thereby causing measurement errors. Therefore, an information data collection device for quota measurement is proposed to solve the problems raised in the background technology. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides an information data collection device for quota measurement, which solves the problem of measurement error when people use handheld laser rangefinders to measure the depth of pile holes.

[0005] To achieve the above object, the present invention provides the following technical solution: an information data collection device for quota determination, comprising an outer shell, and also comprising:

[0006] The support assembly and the protection assembly are cross-arranged in a circular array inside the outer shell, and the locking assemblies are distributed in a circular array on the top of the outer shell;

[0007] A vertical component, the vertical component is arranged in the inner cavity of the outer shell;

[0008] An elastic support ring, which is annular and sleeved outside the outer shell, initially, the elastic support ring has a downward trend due to the tension of a tension spring connected between the elastic support ring and the outer shell;

[0009] The vertical assembly includes a cylindrical rod movably connected to the middle of the outer shell, a convex column is connected to the bottom ball shaft of the cylindrical rod, and a laser rangefinder for measuring the depth of the pile hole is fixedly installed at the bottom of the convex column. The bottom of the cylindrical rod is elastically supported by an elastic top bead, and the bottom end of the elastic top bead is used to squeeze the convex column. The outer circumference array of the cylindrical rod is fixedly connected with a connecting rod, and the bottom end of the connecting rod is fixedly connected to the elastic support ring.

[0010] The support assembly includes a first bracket in an annular array and hinged on the outer shell, a first spring is fixedly connected between the two hinges, a second bracket is also hinged on the top, and a second spring is fixedly connected at the hinge between the second bracket and the first bracket, a convex block is fixedly connected to the bottom end of the second bracket, and the bottom end of the second bracket is movably clamped on the top of the first bracket and used to limit the rotation angle of the second bracket;

[0011] The locking assembly includes a top cover sleeved on the top of the outer shell, an elastic block in a circumferential array and elastically supported inside the outer shell, and an elastic inclined block elastically connected to the inner part of the outer shell and penetrating upward through the elastic block and fixed to the top cover. Initially, the elastic block is clamped into the annular groove formed on the cylindrical rod by its own elastic force;

[0012] After the elastic inclined block moves upward to squeeze the inner wall of the elastic clamping block and makes it separate from the annular groove, the elastic support ring moves downward under its own tension, gradually releasing the squeezing of the second bracket and the first bracket;

[0013] The center of gravity of the laser rangefinder is at the bottom.

[0014] Preferably, the top cover initially maintains a downward trend due to the tension of the tension spring at the bottom of the elastic inclined block, and the bottom of the elastic clamping block close to one end of the cylindrical rod is in an inclined shape.

[0015] Preferably, both the first bracket and the second bracket have a tendency to rotate toward a side away from the outer shell, and the maximum rotation angle of the first bracket is ninety degrees.

[0016] Preferably, the second mainsprings are grouped in pairs and are located at two sides of the bottom end of the second bracket. The maximum rotation angle of the second bracket relative to the second bracket is limited by the protrusion to be sixty degrees.

[0017] Preferably, when the elastic support ring descends to the bottom, its top is used to support the first bracket after rotating ninety degrees.

[0018] Preferably, the cylindrical rod descends to the bottom of the outer shell and is supported by the bottom step thereof to remain stationary, and the diameter of the laser rangefinder is smaller than the diameter of the bottommost opening of the outer shell.

[0019] Preferably, a rolling ball is provided at the bottom end of the elastic top ball, which is supported by the upper spring to squeeze the spherical part of the top of the protruding column.

[0020] When the first bracket and the second bracket rotate to the maximum extent, the laser rangefinder synchronously descends to the bottom of the outer shell cover, and the bottom end height of the laser rangefinder is located below the bottom height of the second bracket. A display screen for displaying measurement data of the laser rangefinder is provided on the top of the outer shell cover.

[0021] Preferably, the protection assembly includes a circumferential array of limiting grooves opened inside the outer shell and a spring piece movably connected inside the limiting grooves;

[0022] Initially, the laser rangefinder is squeezed by the shrapnel to remain stable in the outer shell cover. The top of the shrapnel is fixedly connected to the inner wall of the outer shell cover, and the bottom of the shrapnel is movably connected to the bottom of the limiting groove. When the cylindrical rod moves downward, the shrapnel is squeezed to shrink into the limiting groove and the stability of the laser rangefinder is released.

[0023] Preferably, initially, the middle portion of the spring piece is semi-arc-shaped and convex toward one side of the laser rangefinder. Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The above scheme makes it easy to keep the laser rangefinder perpendicular to the pile hole and reduce the error by cooperating with the first bracket, the first spring, the elastic block and the cylindrical rod. The elastic block is pulled upward by pulling the top cover to disengage the annular groove and release the clamping of the cylindrical rod. At this time, the elastic support ring moves downward and gradually releases the restriction on the second bracket and the first spring. The second bracket and the first bracket rotate respectively under the elastic force of the second spring and the first spring. When the elastic support ring moves downward to the bottom, the first bracket, the second bracket and the laser rangefinder are as shown in the attached figure. Fig. 9 As shown in , the device is then placed above the pile hole. At this time, the bottom end of the laser rangefinder is kept vertical to the pile hole by gravity, and the bottom end of the protruding column is squeezed by the elastic top bead to reduce the swing amplitude of the laser rangefinder after the device is placed, so that it can accurately measure the depth of the pile hole and finally display the measured data on the display screen;

[0025] The present invention cooperates with structures such as the spring sheet and the limiting groove, so that the device has the function of preventing the laser rangefinder from being damaged by collision inside the outer shell when being carried around. During the upward movement of the cylindrical rod, the spring sheet squeezed by the bottom thereof is first retracted into the limiting groove, and then as the laser rangefinder moves upward, the spring sheet is reset by its own elastic force and squeezes the laser rangefinder to support it, thereby preventing the laser rangefinder from being damaged by collision with the outer shell when being carried around.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 11 As shown, the present invention provides an information data collection device for quota determination, including an outer shell 100, and also including:

[0040] The support assembly 200 and the protection assembly 600 are intersected and arranged in a circular array inside the outer shell 100, and the locking assembly 300 is distributed in a circular array on the top of the outer shell 100;

[0041] A vertical assembly 400, the vertical assembly 400 is disposed in the inner cavity of the outer shell 100;

[0042] The elastic support ring 500 is annular and sleeved on the outer shell cover 100. Initially, the elastic support ring 500 has a downward trend due to the tension of the tension spring connected between the elastic support ring 500 and the outer shell cover 100.

[0043] The vertical assembly 400 includes a cylindrical rod 401 movably connected to the middle of the outer shell 100, a protruding column 402 is connected to the bottom ball shaft thereof, and a laser rangefinder 700 for measuring the depth of the foundation pile hole is fixedly installed at the bottom of the protruding column 402, an elastic top bead 403 is elastically supported at the bottom of the cylindrical rod 401, and its bottom end is used to squeeze the protruding column 402, and a connecting rod 404 is fixedly connected to the outer circumference array of the cylindrical rod 401, and its bottom end is fixedly connected to the elastic support ring 500;

[0044] The support assembly 200 includes a first bracket 201 in an annular array and hinged on the outer shell 100, a first spring 202 is fixedly connected between the hinged part of the two, a second bracket 203 is also hinged on the top thereof, and a second spring 204 is fixedly connected at the hinged part between the second bracket 203 and the first bracket 201, a convex block 2031 is fixedly connected to the bottom end of the second bracket 203, and the bottom end of the convex block 2031 is movably clamped on the top of the first bracket 201 and used to limit the rotation angle of the second bracket 203;

[0045] The locking assembly 300 includes a top cover 303 sleeved on the top of the outer shell 100, elastic blocks 301 arranged in a circumferential array and elastically supported inside the outer shell 100, and an elastic inclined block 302 elastically connected to the inner part of the outer shell 100 and penetrating upwardly through the elastic block 301 and fixedly connected with the top cover 303. Initially, the elastic block 301 is clamped into the annular groove 304 provided on the cylindrical rod 401 by its own elastic force;

[0046] After the elastic inclined block 302 moves upward to squeeze the inner wall of the elastic clamping block 301 and separates it from the annular groove 304, the elastic support ring 500 moves downward under its own tension, thereby releasing the squeezing of the second bracket 203 and the first bracket 201;

[0047] The center of gravity of the laser rangefinder 700 is at the bottom.

[0048] By adopting the above solution, the elastic inclined block 302 is driven upward by pulling the top cover 303, so that the elastic clamping block 301 is separated from the annular groove 304 and the clamping connection with the cylindrical rod 401 is released. At this time, the elastic support ring 500 moves downward and gradually releases the restriction on the second bracket 203 and the first spring 202. The second bracket 203 and the first bracket 201 are rotated by the elastic force of the second spring 204 and the first spring 202 respectively. When the elastic support ring 500 moves downward to the bottom, the first bracket 201, the second bracket 203 and the laser rangefinder 700 are as shown in the attached figure. Fig. 9 As shown in , the device is then placed above the pile hole. At this time, the bottom end of the laser rangefinder 700 is kept vertical to the pile hole by gravity, and the bottom end of the raised column 402 is squeezed by the elastic top bead 403 to reduce the swing amplitude of the laser rangefinder 700 after the device is placed, so that it can accurately measure the depth of the pile hole and finally display the measured data on the display screen.

[0049] like Figure 5-7 As shown, the top cover 303 initially maintains a downward trend due to the tension of the tension spring at the bottom of the elastic inclined block 302, and the bottom of the elastic block 301 close to the cylindrical rod 401 is inclined;

[0050] By adopting the above scheme, when the cylindrical rod 401 moves upward to reset, its top end will squeeze the bottom inclined surface of the elastic block 301, and when the cylindrical rod 401 moves upward to the top, the elastic block 301 will be inserted into the cylindrical rod 401 again, and supported and fixed by the plane on the top of the elastic block 301.

[0051] like Figure 1-4 and Figure 8-11 As shown, both the first bracket 201 and the second bracket 203 have a tendency to rotate away from the outer housing 100, and the maximum rotation angle of the first bracket 201 is ninety degrees;

[0052] The second springs 204 are grouped in pairs and are located at both sides of the bottom of the second bracket 203. The second bracket 203 is limited by the protrusion 2031 to a maximum rotation angle of 60 degrees relative to the second bracket 203.

[0053] When the elastic support ring 500 descends to the bottom, its top is used to support the first bracket 201 after rotating 90 degrees;

[0054] With the above solution, when the first bracket 201 and the second bracket 203 rotate to the adjacent Fig. 9 After the state shown, the top of the elastic support ring 500 will support the lower surface of the first bracket 201 and keep it stable.

[0055] like Figure 1-5 and Figure 8-11As shown, the cylindrical rod 401 descends to the bottom of the outer shell 100 and is supported by the bottom step thereof to remain stationary, and the diameter of the laser rangefinder 700 is smaller than the diameter of the bottom opening of the outer shell 100;

[0056] A ball is arranged at the bottom of the elastic top ball 403, which is supported by the upper spring to squeeze the spherical part at the top of the protruding column 402;

[0057] When the first bracket 201 and the second bracket 203 rotate to the maximum extent, the laser rangefinder 700 moves synchronously downward to the bottom of the outer shell 100, and the bottom end of the laser rangefinder 700 is located below the bottom of the second bracket 203. The top of the outer shell 100 is provided with a display screen for displaying the measurement data of the laser rangefinder 700.

[0058] Using the above solution, when the laser rangefinder 700 moves downward to the Fig. 9 As shown, there is a gap between the outer wall of the laser rangefinder 700 and the inner wall of the outer shell cover 100, so that the laser rangefinder 700 can shake inside the outer shell cover 100. Since its top end is fixed by the raised column 402, the bottom end of the laser rangefinder 700 will be affected by gravity and its posture can be corrected to a vertical state by its own center of gravity. At the same time, the ball at the bottom end of the elastic top ball 403 will squeeze the spherical part at the top of the raised column 402 and reduce the amplitude of the shaking of the raised column 402 driven by the laser rangefinder 700, so that the laser rangefinder 700 is quickly stabilized.

[0059] like Figure 2 and Figure 4-5 As shown, the protection assembly 600 includes a circumferential array of limiting grooves 602 opened inside the outer shell 100 and a spring piece 601 movably connected thereto;

[0060] Initially, the laser rangefinder 700 is squeezed by the spring sheet 601 to maintain stability in the outer shell cover 100. The top of the spring sheet 601 is fixedly connected to the inner wall of the outer shell cover 100, and the bottom of the spring sheet 601 is movably connected to the bottom of the limiting groove 602. When the cylindrical rod 401 moves downward, the spring sheet 601 is squeezed to shrink into the limiting groove 602, and the laser rangefinder 700 is released from stability.

[0061] Initially, the middle portion of the spring piece 601 is semi-arc-shaped and bulges toward one side of the laser rangefinder 700;

[0062] By adopting the above scheme, during the upward movement of the cylindrical rod 401, the elastic sheet 601 squeezed by its bottom is first retracted into the limiting groove 602, and then as the laser rangefinder 700 moves upward, the elastic sheet 601 is gradually reset by its own elastic force and squeezes the laser rangefinder 700 to support it, thereby preventing it from being damaged by collision with the outer shell cover 100 when carried around.

[0063] The working principle and use process of the present invention:

[0064] The operator pulls the top cover 303 to drive the elastic inclined block 302 upward, so that the elastic block 301 is separated from the annular groove 304 and releases the clamping of the cylindrical rod 401. At this time, the elastic support ring 500 moves downward under the tension of the bottom spring, and the restriction on the second bracket 203 and the first spring 202 is gradually released. At this time, the second bracket 203 and the first bracket 201 are rotated by the elastic force of the second spring 204 and the first spring 202 respectively. When the elastic support ring 500 moves downward to the bottom, the first bracket 201, the second bracket 203 and the laser rangefinder 700 are as shown in the attached figure. Fig. 9 As shown in , the device is then placed above the pile hole. At this time, the bottom end of the laser rangefinder 700 is kept vertical to the pile hole by gravity, and the bottom end of the protruding column 402 is squeezed by the elastic top bead 403 to reduce the swing amplitude of the laser rangefinder 700 after the device is placed, so that it can quickly measure the depth of the pile hole and finally display the measured data on the display screen;

[0065] When the cylindrical rod 401 moves downward, the raised portion in the middle of the spring sheet 601 is squeezed and retracted into the limiting groove 602. When the cylindrical rod 401 moves downward to the bottom, the spring sheet 601 is reset, and the raised portion is located above the larger diameter portion of the bottom of the cylindrical rod 401.

[0066] After the device measurement is completed, the operator pulls the annular portion of the elastic support ring 500 upwards, and makes it squeeze the first bracket 201 and the second bracket 203 in turn, so that both are reset to the initial state. At the same time, the upward movement of the elastic support ring 500 will also drive the vertical component 400 to reset upward and be re-engaged by the locking component 300 to complete the reset;

[0067] During the upward movement of the cylindrical rod 401, its bottom will squeeze the spring piece 601 to shrink into the limiting groove 602 first, and then as the laser rangefinder 700 moves upward, the spring piece 601 will gradually reset due to its own elastic force and squeeze the laser rangefinder 700 to fix it, thus completing the operation.
