Description

Technical Field

[0001] The utility model relates to the field of project cost, and specifically relates to an information collection and recording device for project cost. Background Art

[0002] Project cost is the construction price of a project, which refers to the total cost required, expected or actual, to complete the construction of a project. In the early stage of project cost, during the project decision-making and design stages, an information collection and recording device can provide basic data support for project cost. For example, information such as the topography and geologic conditions of the land can be collected through devices such as a Geographic Information System (GIS). Such information is crucial for estimating the land acquisition cost, foundation engineering cost, etc. At the same time, using professional measuring devices to collect data on the surrounding environment of the project construction site, such as traffic conditions and supporting facilities, helps to evaluate the external costs and potential benefits of the project, thereby enabling more accurate investment estimation and design budgetary estimate.

[0003] In the prior art, such as the "information collection and recording device" with the patent number CN220228608U, it includes a threaded rod, a toolbox, and a base. A stabilizing structure is provided on the outer sidewall of the threaded rod. A threaded cylinder is welded to the upper end of the base, and a limiting cylinder is sleeved on the upper end of the threaded rod. The stabilizing structure includes a hexagonal ring seat, a diagonal support plate, and three bolts. Fixed seats are fixedly installed at the upper ends of the three diagonal support plates; by providing the threaded rod and the fixed support plate, the fixed support plate can limit the toolbox, and the threaded rod can support the fixed support plate. When the threaded rod is inserted into the threaded cylinder and with the cooperation of the base, it can achieve a supporting effect, thereby facilitating the support of the toolbox, preventing the operator from using both hands for a long time to collect and record information, preventing fatigue of the operator's hands, and improving the collection and recording efficiency of the operator. At the same time, under the threaded cooperation of the threaded rod and the threaded cylinder, by rotating the threaded rod, the lower part of the threaded rod can move up and down inside the threaded cylinder under the threaded cooperation with the threaded cylinder, and thus the height of the fixed support plate can be adjusted.

[0004] In the prior art, as in the above patent, it has high requirements for the ground flatness and needs to be placed on a relatively flat ground to function well. If the ground is uneven, the angle adjustment of the three diagonal support plates may be restricted, affecting the overall stability. When conducting topographic surveys, such as when using equipment such as total stations and GPS surveying instruments to work in cooperation with the information collection and recording device, if the device is not level, it will cause deviations in the measured angles and distances, affecting the accuracy of the finally generated topographic map. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides an information collection and recording device for project cost, which solves the problem of deviation caused by the device not being level during topographic surveying and mapping, and the low accuracy of the finally generated topographic map.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: An information collection and recording device for project cost includes a collection device body for information collection and recording and a bracket. One end of the bracket is fixedly installed with a housing, and a sphere is rotatably installed at the bottom of the housing. The contact part between the housing and the sphere is sealed with a sealing structure. A support rod is installed inside the sphere. The support rod passes through the center position of the sphere and is fixed to it. A gravity ball is fixedly installed at the bottom end of the support rod, and a rotating mechanism for fixing the collection device body is fixedly installed at the other end of the support rod. A notch for accommodating the maximum swing amplitude of the support rod is left at the bottom of the housing. A positioning ring for preventing the sphere from rotating is slidably installed inside the housing. An elastic force is applied downward to the top surface of the positioning ring. An annular groove for air intake is opened inside the positioning ring. An air inlet pipe is communicated with the outer surface of the housing, and the positioning ring is separated from the sphere by gas.

[0007] When the sphere is in a non-locked state, the center line connecting the centers of gravity of the collection device body, the rotating mechanism, the sphere, the gravity ball, and the support rod is perpendicular to the ground.

[0008] Preferably, the rotating mechanism includes a bottom shell, a mounting seat, and a conical grinding block with anti-slip treatment. The bottom shell is fixedly connected to the support rod. The collection device body is installed on the upper part of the mounting seat. A placement groove is opened inside the bottom shell. The bottom end of the mounting seat is fixedly connected to the conical grinding block and is rotatably and slidably connected to the upper end of the placement groove.

[0009] Preferably, the collection device body and the mounting seat are fixed by magnetic attraction.

[0010] Preferably, a rotating ring is rotatably installed at the upper end of the bottom shell. A lever mechanism is installed on the upper surface of the rotating ring. A gravity block is fixedly connected to the outer surface of the mounting seat. The lever mechanism is movably installed with the gravity block and is used to lift the gravity block. A counterweight block is fixedly connected to the outer surface of the rotating ring.

[0011] Preferably, the lever mechanism includes a pry bar, a central shaft, two support blocks, and two short plates. Slide grooves are opened inside both short plates. Both ends of the gravity block are cylindrical and are respectively slidably connected to the two slide grooves. Both support blocks are fixedly connected to the rotating ring. The central shaft passes through the two support blocks and is rotatably connected to the two support blocks. The central shaft is fixedly connected to the pry bar and is also fixedly connected to the two short plates.

[0012] Preferably, the sealing structure is made of rubber material in a ring shape.

[0013] Preferably, a side surface of the positioning ring close to the sphere is configured as a curved surface adapted to the sphere, and the two are in close contact.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The information collection and recording device for engineering cost, when the set sphere is in a non-locked state, the connecting line of the center of gravity of the collection equipment body, the rotating mechanism, the sphere, the gravity ball and the support rod is vertical to the ground, ensuring that the collection equipment body automatically remains horizontal when working in an uneven terrain environment. When the positioning ring contacts the sphere, a closed space is formed between the shell and the sphere. By delivering gas, the positioning ring is separated from the sphere under the push of air pressure. When the collection equipment body needs to be horizontal again, it is helpful to reduce the resistance encountered by the sphere during rotation during the adjustment process. After the adjustment is completed, the downward elastic force applied by the top surface of the positioning ring resets the positioning ring and limits the sphere, so as to achieve the purpose of positioning the sphere and prevent the collection equipment body from tilting, so as to meet the needs of surveying and mapping work.

[0016] 2. The information collection and recording device for engineering cost displaces the gravity block by prying the lever mechanism, thereby causing the conical grinding block to break contact with the placement slot, thereby separating the two, which is conducive to easily rotating the mounting seat and adjusting the rotation angle of the collection device body. By setting the gravity block, the gravity of the gravity block increases the squeezing force between the conical grinding block and the placement slot, thereby increasing the friction force, so that the conical grinding block is firmly stuck in the bottom of the placement slot, which is conducive to fixing the position of the adjusted collection device body.

Specific embodiments

[0023] Such as Figures 1 - 5As shown in the figure, an information collection and recording device for project cost includes a collection device body 1 for information collection and recording and a bracket 2. The collection device body 1 is located directly above the bracket 2. The bracket 2 is installed with an external tripod. One end of the bracket 2 is fixedly installed with a housing 3. The bottom of the housing 3 is semi-circular, and the upper part of the housing 3 is cylindrical. A sphere 4 is rotatably installed at the bottom of the housing 3. The contact part between the housing 3 and the sphere 4 is sealed by a sealing structure. The sealing structure is made of rubber in a ring shape. The sealing structure is fixed to the housing 3 and is in close contact with the sphere 4 to ensure the fixed position of the sealing structure and seal between the sphere 4 and the housing 3 to prevent gas leakage from between their bottoms. A support rod 5 is installed inside the sphere 4. The support rod 5 passes through the center of the sphere 4 and is fixed to it. A gravity ball 6 is fixedly installed at the bottom end of the support rod 5. The other end of the support rod 5 is fixedly installed with a rotating mechanism 7 for fixing the collection device body 1. The rotating mechanism 7 includes a bottom shell 701, a mounting seat 702, and a tapered grinding block 703 with anti-slip treatment. The bottom shell 701 is fixedly connected to the support rod 5. The collection device body 1 is installed on the upper part of the mounting seat 702. A placement groove 11 with a tapered bottom and a cylindrical upper end is opened inside the bottom shell 701, and they are in close contact. The bottom end of the mounting seat 702 is fixedly connected to the tapered grinding block 703 and is rotatably and slidably connected to the upper end of the placement groove 11. The collection device body 1 is fixed to the mounting seat 702 by magnetic attraction, so that the collection device body 1 adjusts its angle as the rotating mechanism 7 rotates. A rotating ring 12 is rotatably installed at the upper end of the bottom shell 701. A lever mechanism 13 is installed on the upper surface of the rotating ring 12. A gravity block 14 is fixedly connected to the outer surface of the mounting seat 702. The lever mechanism 13 is movably installed with the gravity block 14. The lever mechanism 13 is used to lift the gravity block 14 to make the tapered grinding block 703 disengage from the placement groove 11. A counterweight block 15 is fixedly connected to the outer surface of the rotating ring 12, and the counterweight block 15 is located on the opposite side of the lever mechanism 13 to make the two sides of the rotating ring 12 have balanced forces. By prying the lever mechanism 13, the gravity block 14 is displaced, and then the tapered grinding block 703 is disengaged from the placement groove 11, so that the friction between them is lost, which is beneficial to easily rotate the mounting seat 702 and adjust the rotation angle of the collection device body 1. By setting the gravity block 14, the gravity of the gravity block 14 increases the extrusion force between the tapered grinding block 703 and the placement groove 11, thereby increasing the friction force and making the tapered grinding block 703 firmly snap into the bottom of the placement groove 11, which is beneficial to fixing the position of the adjusted collection device body 1. The lever mechanism 13 includes a pry bar 131, a central shaft 132, two support blocks 133, and two short plates 134. Sliding grooves 16 are opened inside both of the two short plates 134. The two ends of the gravity block 14 are cylindrical and are respectively slidably connected to the two sliding grooves 16. Both of the two support blocks 133 are fixedly connected to the rotating ring 12. The central shaft 132 passes through the two support blocks 133 and is rotatably connected to the two support blocks 133. The central shaft 132 is fixedly connected to the pry bar 131.It is also fixedly connected to the two short plates 134. The length of the lever 131 is greater than that of the short plates 134, so that the lever 131 and the two short plates 134 swing around the central axis 132 as a fulcrum, making it easier to pry the gravity block 14. There is a notch at the bottom of the housing 3 for accommodating the maximum swing amplitude of the support rod 5. A positioning ring 8 for preventing the sphere 4 from rotating is slidably installed inside the housing 3. An elastic force is applied downward to the top surface of the positioning ring 8. The side surface of the positioning ring 8 close to the sphere 4 is set as an arc surface adapted to the sphere 4, and the two are in close contact to increase the contact area between them, thereby increasing the friction force and facilitating the fixation of the sphere 4. An annular groove 9 for air intake is opened inside the positioning ring 8. The cross-section of the annular groove 9 is trapezoidal to carry enough gas to make it effectively displace. An air inlet pipe 10 is connected to the outer surface of the housing 3, and the gas is sequentially passed through the air inlet pipe 10, the housing 3, the gap between the housing 3 and the sphere 4 and reaches the annular groove 9 through an external air pump, and the positioning ring 8 is separated from the sphere 4 by the gas. When it is necessary to re-level the collection device body 1, it is beneficial to reduce the resistance suffered by the sphere 4 during rotation in the adjustment process;

[0024] When the sphere 4 is in a non-locked state, the center of gravity connection line of the collection device body 1, the rotating mechanism 7, the sphere 4, the gravity ball 6 and the support rod 5 is perpendicular to the ground.

[0025] Working principle:

[0026] First, the acquisition device body 1 is fixed to the mounting base 702 by magnetic attraction, and then the bottom of the bracket 2 is fixed to the external tripod, and the tripod is placed on the ground. When it is on an uneven ground, the gas is first transported to the air inlet pipe 10 through an external air pump. The gas passes through the air inlet pipe 10, the shell 3, and the gap between the shell 3 and the sphere 4 in turn and reaches the annular groove 9. Since the positioning ring 8 squeezes the sphere 4, a closed space is formed between the sphere 4, the positioning ring 8 and the shell 3. When the gas enters the above-mentioned closed space, the gas pushes the positioning ring 8 to rise and break away from the sphere 4 under the push of air pressure. It should be noted that the positioning ring 8 does not need to be displaced too much, and a small offset of the sphere 4 is sufficient to achieve the purpose of separating the positioning ring 8 from the sphere 4. When the ground is uneven, the gravity ball 6 will swing under the action of its gravity. Until the gravity center connection line of the acquisition device body 1, the rotating mechanism 7, the sphere 4, the gravity ball 6 and the support rod 5 is perpendicular to the ground, and the acquisition device body 1 will gradually tend to a horizontal state with the gravity ball 6. When the gravity ball 6 is stable, the gas output is stopped. Since the top surface of the positioning ring 8 applies a downward elastic force to apply a downward pushing force to the positioning ring 8, the positioning ring 8 begins to reset and squeeze the sphere 4, and cooperates with the arc surface setting of the positioning ring 8 to increase the contact area between the positioning ring 8 and the sphere 4, thereby increasing the friction force, making it easier to fix the sphere 4, so that the sphere 4 remains stable, and the purpose of positioning the sphere 4 is achieved, thereby improving the stability of the acquisition device body 1, ensuring that the acquisition device body 1 automatically remains horizontal when working in an uneven terrain environment, and preventing the measured angle and distance from deviations during terrain surveying and mapping, thereby affecting the accuracy of the final generated topographic map.

[0027] Next, when it is necessary to adjust the rotation angle of the acquisition device body 1, first press the pry bar 131, so that the pry bar 131 and the two short plates 134 swing with the central axis 132 as the fulcrum, and the two short plates 134 pry the gravity block 14 up, and the gravity block 14 drives the mounting seat 702 to rise, and the mounting seat 702 drives the conical grinding block 703 to rise, and the conical grinding block 703 is separated from the bottom of the placement groove 11, so that the mounting seat 702 is driven to rotate by the pry bar 131, so as to adjust the rotation angle of the acquisition device body 1. Since the length of the pry bar 131 is greater than the length of the short plate 134, the lever principle is used to make it easier to pry the gravity block 14. It should be noted that the conical grinding block 703 does not need to move too much distance After the adjustment is completed, the pry bar 131 is released, and under the gravity of the acquisition device body 1 and the gravity block 14, the mounting seat 702 drives the conical grinding block 703 to move vertically downward, and reinserts the conical grinding block 703 into the bottom of the placement groove 11. Due to the large contact area between the conical setting of the conical grinding block 703 and the bottom of the placement groove 11, and the gravity of the acquisition device body 1, the mounting seat 702 and the gravity block 14 are cooperated, not only the conical grinding block 703 is firmly stuck in the bottom of the placement groove 11, but also the friction between the two is increased, making the conical grinding block 703 and the mounting seat 702 more stable, thereby achieving the purpose of fixing the rotation angle of the acquisition device body 1.
