Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, and more specifically, to a construction engineering cost analysis device. Background Technology

[0002] Construction project cost refers to the total amount of all construction expenses invested in the entire process of construction from planning to completion and acceptance. It consists of construction and installation costs, equipment and tool purchase costs, other construction costs, contingency funds, and taxes. It is both the total fixed asset investment and current asset investment required by the investor (owner) to complete the project, and the contract price obtained by the contractor through contracting transactions.

[0003] For example, Chinese utility model patent CN220041362U discloses a construction engineering cost analysis device, belonging to the field of engineering cost technology. It includes a base, with a telescopic sleeve fixed to the upper middle part of the base. A fastening bolt is installed on the fixed arm of the telescopic sleeve. A rotating shaft is inserted through one end of the telescopic sleeve, and a display panel is fixed to the other end of the rotating shaft. This utility model designs a rotating limiting mechanism consisting of a rotating shaft, a limiting hole, a limiting rod, a lever, a telescopic column, and a spring. During the display process, the orientation of the display panel can be adjusted according to the layout of the report. By applying external force to the lever, the limiting rod separates from the limiting hole, releasing the display panel for adjustment. After adjustment, releasing the external force allows the limiting rod to automatically reset and fix the display panel, effectively improving the device's applicability.

[0004] During construction, it is necessary to use analytical devices to analyze the construction cost. However, existing analytical devices require the use of magnets or other fixing objects to fix the construction cost table and other data onto the analytical panel.

[0013] As a further embodiment of the present invention: the moving component includes a receiving groove, a spring and a connecting block; at least one receiving groove is provided on the front side of the support base, and the storage box is slidably engaged with the receiving groove; one end of the spring is fixedly connected to the inner side wall of the receiving groove; the connecting block is slidably disposed in the receiving groove and fixedly connected to the storage box, and the connecting block is fixedly connected to the other end of the spring.

[0015] As a further aspect of the present invention: the movable groove is an isosceles triangular structure, the side of the movable groove near the storage box is a concave end, the side of the movable groove away from the storage box is a pointed end, the inner and outer walls of the pointed end and the concave end of the movable groove are staggered, and the outer wall arc of the side end of the movable groove is larger than the inner wall arc.

[0016] The beneficial effects of this invention are as follows: 1. This invention, through the setting of a lifting component and the driving component, connects the screw to the sliding block threadedly. The sliding block drives the external and internal threaded cylinders to slide upwards within the sliding block, causing the key block to slide within the keyway. When the screw rotates, the inner wall of the keyway presses against the key block, causing the external threaded cylinder to rotate with the screw. This causes the connecting ring to rotate within the connecting groove, connecting the internal and external threaded cylinders threadedly. Since the internal threaded cylinder is fixedly connected to the top wall of the sliding groove, it moves upwards, achieving twice the travel distance. This allows the analysis plate body to slide outwards within the receiving groove until it reaches the desired position. Compared to existing technologies, this invention has a reasonable structural design. By performing multi-stage lifting of the analysis plate body, it not only reduces the overall volume of the analysis device, making it easier to carry, but also reduces space occupancy. Furthermore, it protects the analysis plate body and extends its service life.

[0017] 2. This invention, by setting up a drive component, starts a servo motor, causing the output shaft of the servo motor to drive the corresponding screw to rotate, causing the driving wheel to rotate, which in turn drives the driven wheel to rotate via a belt, causing the rotating rod to rotate through the rotating shaft A and the bottom wall of the storage groove, thus driving the corresponding screw to rotate. This not only reduces the cost of use but also allows the two screws to rotate synchronously, ensuring transmission accuracy.

[0018] 3. This invention, by setting up a movable component, allows the storage box to slide within the receiving groove when pressed, causing the connecting block to slide. This causes the spring to contract, resulting in the movable pin sliding from the concave end of the moving groove to the side end. The connecting plate then rotates against the inner wall of the receiving groove via the rotating shaft B until the movable pin reaches the side end of the moving groove. At this point, releasing the storage box causes the connecting block to slide in the opposite direction within the receiving groove under the spring force, allowing the movable pin to slide from the side end to the tip of the moving groove. The connecting plate then rotates against the inner wall of the receiving groove via the rotating shaft B until the movable pin reaches the tip of the moving groove. At this point, the storage box's storage groove is outside the receiving groove, allowing the fixed object inside to be removed. This not only enables the storage of objects but also maintains the overall aesthetic appeal of the analytical device. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 10 As shown, the present invention provides a construction project cost analysis device, including a device body 1 for construction project cost analysis, a storage mechanism 2, storage boxes 5, and a moving component 6; the device body 1 includes a support base 101 and an analysis plate body 102; the analysis plate body 102 is connected to the support base 101 through the storage mechanism 2, and an iron sheet is provided on the front of the analysis plate body 102; the storage mechanism 2 includes a lifting component 3 and a driving component 4; the lifting component 3 is disposed inside the analysis plate body 102; the driving component 4 is disposed on the lifting component 3 and is located inside the support base 101; two storage boxes 5 are connected to the front of the support base 101 through the moving component 6, and the storage boxes 5 are used to store the fixing objects for fixing the construction project cost table; a control panel is provided on the support base 101, and the control panel model is LC-M2E; The lifting assembly 3 includes a storage slot 301, a sliding square slot 302, a sliding square cylinder 303, a fixing plate 304, a sliding block 305, a screw 306, an external threaded cylinder 307, a connecting slot 308, a connecting ring 309, and an internal threaded cylinder 310; the support base 101 has a storage slot 301 on its top surface; two sliding square slots 302 are symmetrically opened on the bottom surface of the analysis plate body 102; the sliding square cylinder 303 slides through the sliding square slots 302; the two A fixed plate 304 is symmetrically fixedly connected to the bottom surface of the sliding square tube 303, and the fixed plate 304 is fixedly connected to the inner bottom wall of the storage groove 301; the sliding block 305 is slidably disposed inside the sliding square tube 303; the screw 306 is screwed through the sliding block 305, and the threaded connection between the screw 306 and the sliding block 305 has a self-locking function; the external threaded cylinder 307 is sleeved on the screw 306; a connecting groove 308 is opened on the top surface of the sliding block 305; The connecting ring 309 is rotatably inserted into the connecting groove 308 and fixedly connected to the bottom surface of the external threaded cylinder 307; the internal threaded cylinder 310 is screwed onto the external threaded cylinder 307 and fixedly connected to the inner top wall of the sliding square groove 302. The threaded connection between the internal threaded cylinder 310 and the external threaded cylinder 307 has a self-locking function; the receiving groove 301 has a convex structure with a larger upper part and a smaller lower part to ensure that the moving component 6 has design space without affecting the movement of the analysis plate body 102; a keyway is provided on the circumferential surface of the screw 306, and a key block is provided on the inner circumferential surface of the external threaded cylinder 307, and the key block slides with the keyway; the longitudinal section of the connecting ring 309 is a Y-shaped structure with a smaller upper part and a larger lower part. The inner and outer diameters of the top surface of the connecting ring 309 are adapted to the inner and outer diameters of the external threaded cylinder 307, and the shape of the connecting ring 309 is adapted to the shape of the connecting groove 308 to facilitate the connection between the external threaded cylinder 307 and the sliding square block 305.

[0023] This invention, by setting up a lifting component 3, uses a driving component 4 to thread a screw 306 onto a sliding block 305. The sliding block 305 causes the external threaded cylinder 307 and the internal threaded cylinder 310 to slide upwards within the sliding block 303, allowing the key block to slide within the keyway. When the screw 306 rotates, it causes the inner wall of the keyway to press against the key block, causing the external threaded cylinder 307 to rotate with the screw 306. This causes the connecting ring 309 to rotate within the connecting groove 308, resulting in a threaded connection between the internal threaded cylinder 310 and the external threaded cylinder 307. Because the internal threaded cylinder 310 is connected to the sliding block... The fixed connection to the inner top wall of 302 causes the internal threaded cylinder 310 to move upward, allowing it to achieve twice the travel distance. This allows the analysis plate body 102 to slide outward within the storage groove 301 until it reaches the desired position. Compared to existing technologies, this invention has a reasonable structural design. By performing multi-stage lifting and lowering of the analysis plate body 102, the overall volume of the analysis device body 1 can be reduced, making it easier to carry and reducing space occupancy. At the same time, it also protects the analysis plate body 102 and extends its service life.

[0024] In a preferred embodiment, the drive assembly 4 includes a battery 401, a servo motor 402, a rotating rod 403, a drive wheel 404, a driven wheel 405, and a belt 406. The battery 401 is detachably mounted on the inner bottom wall of the storage slot 301, and a charging port is provided on the battery 401. The servo motor 402 is fixedly connected to the inner bottom wall of the storage slot 301 via a motor mount, and the output end of the servo motor 402 is fixedly connected to the end of one of the screws 306. One end of the rotating rod 403 is rotatably connected to the inner bottom wall of the storage slot 301 via a rotating shaft A, and the other end is connected to another screw 306. 06. The end is fixedly connected; the driving wheel 404 is sleeved and fixed on the output shaft of the servo motor 402; the driven wheel 405 is sleeved and fixed on the rotating rod 403, and the driving wheel 404 is connected to the driven wheel 405 through the belt 406, which passes between the two fixed plates 304; several tooth blocks are provided on the circumferential surface of the driving wheel 404 and the circumferential surface of the driven wheel 405, and several tooth grooves are provided on the inner wall of the belt 406. The tooth blocks and tooth grooves mesh and drive to avoid slippage between the belt 406 and the driving wheel 404 and the driven wheel 405, which would affect the transmission accuracy.

[0025] This invention, by setting up a drive component 4, activates a servo motor 402, causing the output shaft of the servo motor 402 to drive the corresponding screw 306 to rotate, which in turn causes the drive wheel 404 to rotate. The drive wheel 404 then drives the driven wheel 405 to rotate via a belt 406, causing the rotating rod 403 to rotate with the inner bottom wall of the storage groove 301 via a rotating shaft A. This rotating rod 403 then drives the corresponding screw 306 to rotate. This not only reduces the cost of use but also allows the two screws 306 to rotate synchronously, ensuring transmission accuracy.

[0026] In a preferred embodiment, the movable component 6 includes a receiving groove 601, a spring 602, a connecting block 603, a movable groove 604, a connecting plate 605, and a movable pin 606; two receiving grooves 601 are symmetrically provided on the front of the support base 101, and the storage box 5 is slidably engaged with the receiving groove 601; one end of the spring 602 is fixedly connected to the inner wall of the receiving groove 601; the connecting block 603 is slidably disposed in the receiving groove 601 and fixedly connected to the storage box 5, and the other end of the connecting block 603 is fixedly connected to the spring 602; two movable grooves 604 are symmetrically provided on both sides of the connecting block 603; one end of each of the two connecting plates 605 is connected to the receiving groove 601 via a rotating shaft B. The inner wall is rotatably connected; the movable pin 606 slides through the movable groove 604 and is fixedly connected to the other end of the connecting plate 605; the movable groove 604 is an isosceles triangular structure, with the side of the movable groove 604 near the storage box 5 being a concave end and the side of the movable groove 604 away from the storage box 5 being a pointed end, and the inner and outer walls of the pointed end and the concave end of the movable groove 604 are staggered, and the outer wall arc of the side end of the movable groove 604 is larger than the inner wall arc; when the movable pin 606 slides to the side end of the movable groove 604, the spring 602 is not compressed beyond the elastic range; when the movable pin 606 slides to the concave end of the movable groove 604, the side of the storage box 5 and the side of the support base 101 are on the same vertical plane.

[0027] This invention, by setting up a movable component 6, allows the storage box 5 to slide within the receiving groove 601 when pressed, causing the connecting block 603 to slide within the receiving groove 601. This causes the spring 602 to contract, resulting in the movable pin 606 sliding from the concave end of the moving groove 604 towards its side. This causes the connecting plate 605 to rotate relative to the inner wall of the receiving groove 601 via the rotating shaft B, until the movable pin 606 slides to the side of the moving groove 604. At this point, releasing the storage box 5 allows it to move under the elastic force of the spring 602. The connecting block 603 slides in the opposite direction within the receiving groove 601, causing the moving pin 606 to slide from the side end of the moving groove 604 to the tip of the moving groove 604. This causes the connecting plate 605 to rotate with the inner wall of the receiving groove 601 via the rotating shaft B, until the moving pin 606 slides to the tip of the moving groove 604. At this point, the storage box 5 is located outside the receiving groove 601, allowing the fixed object inside the storage box 5 to be removed. This not only allows for the storage of objects but also ensures the overall aesthetics of the analytical device body 1.

[0028] The battery 401 and servo motor 402 are conventional instruments, and their working principles, dimensions, and models are irrelevant to the problems solved by this application, so they will not be described in detail. The control method of this invention is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0029] The servo motor 402 is model R88M-K, and it is adjusted in real time through a closed-loop feedback mechanism to achieve high-precision control of position, speed and torque, thereby avoiding the need for sensors to achieve precise control; the battery 401 is model NS40ZL.

[0030] Working principle of this invention: In use, the servo motor 402 is started, causing the output shaft of the servo motor 402 to drive the corresponding screw 306 to rotate, which in turn causes the driving wheel 404 to rotate. The driving wheel 404, through the belt 406, drives the driven wheel 405 to rotate, causing the rotating rod 403 to rotate through the rotating shaft A and the inner bottom wall of the receiving groove 301. The rotating rod 403 drives the corresponding screw 306 to rotate, causing the screw 306 to be threadedly connected to the sliding block 305. The sliding block 305 then drives the external threaded cylinder 307 and the internal threaded cylinder 310. The sliding block slides upward within the sliding square tube 303, causing the key block to slide within the keyway. When the screw 306 rotates, the inner wall of the keyway presses against the key block, causing the external threaded cylinder 307 to rotate with the screw 306. This causes the connecting ring 309 to rotate within the connecting groove 308, resulting in a threaded connection between the internal threaded cylinder 310 and the external threaded cylinder 307. Since the internal threaded cylinder 310 is fixedly connected to the top wall of the sliding square groove 302, it moves upward, allowing it to achieve twice the travel distance. This allows the analysis plate body 102 to be stored... The analyzer slides outward from the groove 301 until the analyzer plate body 102 moves to the appropriate position. Then, by pressing the storage box 5, the storage box 5 drives the connecting block 603 to slide within the receiving groove 601. This causes the spring 602 to contract, causing the moving pin 606 to slide from the concave end of the moving groove 604 to the side end of the moving groove 604. This causes the connecting plate 605 to rotate with the inner wall of the receiving groove 601 via the rotating shaft B until the moving pin 606 slides to the side end of the moving groove 604. At this point, releasing the storage box 5, under the elastic force of the spring 602, will cause the storage box 5 to drive the connecting plate 605 to rotate. Block 603 slides in the opposite direction in the receiving groove 601, causing the moving pin 606 to slide from the side end of the moving groove 604 to the tip of the moving groove 604, causing the connecting plate 605 to rotate with the inner wall of the receiving groove 601 through the rotating shaft B, until the moving pin 606 slides to the tip of the moving groove 604. At this time, the storage box 5 is located outside the receiving groove 601, and the fixed object (such as a magnetic block) in the storage box 5 can be taken out so that the data such as the construction cost table can be fixed in the analysis board body 102 by the fixed object in conjunction with the iron plate on the analysis board body 102. After use, remove the fixing object and place it into the storage slot of storage box 5. Press storage box 5 to make it slide the connecting block 603 in the receiving slot 601. This causes the spring 602 to contract, causing the moving pin 606 to slide from the tip of the moving slot 604 to the other side of the moving slot 604. This causes the connecting plate 605 to rotate with the inner wall of the receiving slot 601 via the rotating shaft B until the moving pin 606 slides to the other side of the moving slot 604. At this point, release storage box 5. Under the elastic force of spring 602, storage box 5 will move the connecting block 603. Slide the device in the opposite direction within the receiving groove 601, causing the moving pin 606 to slide from the other end of the moving groove 604 toward the concave end of the moving groove 604 until the moving pin 606 slides to the concave end of the moving groove 604. At this time, the storage box 5 is located within the receiving groove 601. Then, control the servo motor 402 to rotate the output shaft of the servo motor 402 in the opposite direction, causing the analysis plate body 102 to slide inward within the receiving groove 301 until the analysis plate body 102 moves to its original position. The analysis device body 1 can then be moved and carried using the handles on both sides of the support base 101.
