Description

Technical Field

[0001] This utility model relates to the field of engineering cost technology, specifically to an auxiliary device for measuring multi-specification drawings for engineering cost. Background Technology

[0002] Engineering cost consulting refers to accepting commissions from the public to undertake the full-process and dynamic cost management of construction projects, including feasibility studies, investment estimation, project economic evaluation, engineering budget, project settlement, project final settlement, preparation and review of project bidding documents and bid quotations, monitoring of project costs, and providing relevant engineering cost information and data.

[0003] A known authorized patent with publication number CN214230349U discloses an auxiliary device for construction project cost budgeting. Its background art addresses the problem that "existing construction cost budgeting structures are too simplistic. Because cost budgeting requires extensive measurement and calculation, and work projects and construction sites vary, it's difficult to find a flat table for drawing and calculation. The calculated drawings are often carried in a work bag, easily leading to blurred or damaged text." To address this, the proposed solution includes a panel body, with a placement groove fixedly installed at the bottom, a handle fixedly installed at the top, a drawing tube fixedly installed at the back, a fixing spring fixedly installed on the surface, and a fixing clip fixedly installed at the bottom of the fixing spring.

[0004] However, in implementing the relevant technology, the following problems were found in the existing technical solutions: When using the existing drawing measurement auxiliary device, it is inconvenient to lay the drawing flat. Usually, the drawing is unfolded and the four corners are fixed with magnets. However, since the drawing is usually rolled up and stored, some parts of the drawing are prone to wrinkles or curling edges after unfolding, making it difficult to lay flat and contact the board surface. During measurement, personnel still need to smooth the measurement position, which is inconvenient to use and can easily affect the measurement results. Utility Model Content

[0005] This utility model proposes an auxiliary device for measuring multi-specification drawings for engineering cost estimation, which solves the problem of inconvenience in flattening and smoothing drawings in related technologies.

[0006] The technical solution of this utility model is as follows: A multi-specification drawing measurement auxiliary device for engineering cost estimation, comprising: a base and two support shells symmetrically installed on its top; A frame positioned between supporting shells; Rotate the placement plate connected within the frame; Two fixing rods are fixedly installed between the top sides of the front and rear of the placement plate; Two sliding blocks are slidably connected to the surface of the fixed rod; A hand-tightened bolt that is threaded through the sliding block and abuts against the fixed rod; The lower pressure plate is movably mounted at the bottom of the sliding block via a rotating shaft and a torsion spring; Rotate the two smoothing rollers connected to the side of the lower pressure plate near the placement plate; And a flat plate that is fixedly installed on the middle of the side of the lower pressure plate near the placement plate.

[0007] Preferably, the frame is provided with a limiting mechanism for fixing the placement plate.

[0008] The limiting mechanism includes two mounting blocks fixedly installed at the bottom of the frame, a bent rod slidably connected to the mounting blocks, a lock hole opened at the bottom of the placement plate, and a reset component provided on the mounting blocks. The end of the bent rod slidably passes through the frame and is inserted into the lock hole.

[0009] The reset component includes a limiting ring fixedly installed on the surfaces of both ends of the bent rod, and a spring sleeved on the surfaces of both ends of the bent rod. The two ends of the spring are respectively connected to the limiting ring and the mounting block.

[0010] Preferably, the support shell is provided with an adjustment mechanism for adjusting the frame up and down and the angle.

[0011] The adjustment mechanism includes a fixed block fixedly installed inside the support shell, a bent rod slidably connected to the two fixed blocks, a comb-shaped protrusion fixedly connected to the end of the bent rod, a spring 2 sleeved on the surface of both ends of the bent rod, a shaft rotatably connected to the top of the support shell, a cam gear fixedly installed on the surface of the shaft and engaged with the comb-shaped protrusion, and a lifting component provided on the support shell. The opposing surfaces of the two support shells are provided with slots for the bent rod 2 to extend and slide. The two ends of the spring 2 are respectively connected to the fixed block and the comb-shaped protrusion.

[0012] The lifting component includes a guide shell fixedly connected to one end of the shaft, a second hand-tightening bolt threaded through and connected to one side of the guide shell, and a clamping block fixedly connected to one end of the second hand-tightening bolt. The frame is slidably installed inside the guide shell.

[0013] The working principle and beneficial effects of this utility model are as follows: By rotating the lower pressure plate away from the placement plate, after the drawing is unfolded and placed on the placement plate, the spring force of the torsion spring causes the lower pressure plate to return to its original position, initially fixing the drawing. This brings the smoothing roller and the laying plate into contact with the drawing. Then, the sliding blocks are moved to both sides, causing the sliding blocks to move the lower pressure plate to both sides. During this process, the smoothing roller rolls on the drawing to smooth out wrinkles and bends, and the laying plate slides on the surface of the drawing to further smooth out wrinkles. After moving to the edge of the drawing, the position of the sliding blocks is fixed by hand-tightening the bolts. Therefore, under the action of the smoothing roller and the laying plate, the drawing is laid flat and smoothed, avoiding the situation where the traditional fixing method is difficult to lay the drawing flat and affects the measurement. This effectively improves the measurement effect and ease of use of the drawing. Attached Figure Description

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1 - Figure 6The present invention provides an auxiliary device for measuring multi-specification drawings for engineering cost, comprising: a base 1 and two support shells 2 symmetrically installed on its top; The frame 3 is located between the supporting shells 2; Rotate the placement plate 4 connected within the frame 3; Two fixing rods 5 are fixedly installed between the top sides of the front and rear of the placement plate 4; Two sliding blocks 6 are slidably connected to the surface of the fixed rod 5; A hand-tightening bolt 7 is threaded through and connected to the sliding block 6 and abuts against the fixing rod 5; The lower pressure plate 8 is movably mounted at the bottom of the sliding block 6 via a pivot and a torsion spring; Two smoothing rollers 9 are rotatably connected to the side of the lower pressure plate 8 near the placement plate 4; A flat plate 10 is fixedly installed on the lower pressure plate 8 near the middle of one side of the placement plate 4. The smoothing roller 9 and the lowest surface of the flat plate 10 are on the same horizontal line and in contact with the surface of the placement plate 4. The flat plate 10 is a low-friction smooth plate, such as graphene material.

[0018] The technical solution provided in this embodiment is as follows: In use, the lower pressure plate 8 is rotated away from the placement plate 4 to store the torsion spring, and the drawing is unfolded and placed on the placement plate 4. Then, the spring force of the torsion spring causes the lower pressure plate 8 to return to its original position and press against the drawing for initial fixation. The smoothing roller 9 and the laying plate 10 are then brought into contact with the drawing. The sliding block 6 is then moved to both sides, causing the sliding block 6 to move the lower pressure plate 8 to both sides along the surface of the fixing rod 5. During this process, the smoothing roller 9 can roll on the drawing to smooth out wrinkles and bends, and the laying plate 10 can slide on the surface of the drawing to further smooth out wrinkles. The drawing stops at the edge of the drawing, and the hand-tightened bolt 7 is tightened to make it abut against the fixing rod 5, thereby fixing the position of the sliding block 6 and preventing the movement of the sliding block 6 from affecting the fixation of the drawing during measurement. Therefore, under the action of the smoothing roller 9 and the laying plate 10, the drawing is flattened and smoothed, avoiding the situation where the traditional fixing method is difficult to make the drawing flat and affect the measurement. This effectively improves the measurement effect and ease of use of the drawing. Repeating the above operation, a second drawing can be fixed on the back of the placement plate 4 for subsequent switching measurements.

[0019] Furthermore, the frame 3 is provided with a limiting mechanism for fixing the placement plate 4.

[0020] The limiting mechanism includes two mounting blocks 11 fixedly installed at the bottom of the frame 3, a bent rod 12 slidably connected to the mounting blocks 11, a lock hole opened at the bottom of the placement plate 4, and a reset component provided on the mounting blocks 11. The end of the bent rod 12 slidably passes through the frame 3 and is inserted into the lock hole.

[0021] The reset component includes a limiting ring 13 fixedly installed on the surfaces of both ends of the bent rod 12, and a spring 14 sleeved on the surfaces of both ends of the bent rod 12. The two ends of the spring 14 are respectively connected to the limiting ring 13 and the mounting block 11.

[0022] Specifically, by moving the bent rod 12 downwards to separate it from the lock hole, and causing the limiting ring 13 to move downwards to compress the spring 14, the placement plate 4 can rotate within the frame 3 to switch between the front and back sides. This allows for measurement of the front drawing first, followed by rotation to measure the back drawing, facilitating measurement changes and reducing the time spent disassembling and reinstalling the drawings, thus improving the efficiency of drawing measurement. After rotation, by releasing the bent rod 12 and adjusting the position of the placement plate 4 until the bent rod 12 and the lock hole are aligned, the spring force of the spring 14 can move the bent rod 12 upwards to reset and insert it into the lock hole to fix the placement plate 4, ensuring its stability.

[0023] Furthermore, the support shell 2 is provided with an adjustment mechanism for adjusting the frame 3 vertically and at an angle.

[0024] The adjustment mechanism includes a fixed block 15 fixedly installed inside the support shell 2, a bent rod 16 slidably connected to the two fixed blocks 15, a comb-shaped protrusion 17 fixedly connected to the end of the bent rod 16, a spring 18 sleeved on the surfaces of both ends of the bent rod 16, a shaft rotatably connected to the top of the support shell 2, a cam gear 19 fixedly installed on the surface of the shaft and engaged with the comb-shaped protrusion 17, and a lifting component provided on the support shell 2. The opposing surfaces of the two support shells 2 are provided with slots for the bent rod 16 to extend and slide. The two ends of the spring 18 are respectively connected to the fixed block 15 and the comb-shaped protrusion 17.

[0025] The lifting component includes a guide shell 20 fixedly connected to one end of the shaft, a second hand-tightening bolt 21 threadedly connected to one side of the guide shell 20, and a clamping block 22 fixedly connected to one end of the second hand-tightening bolt 21. The frame 3 is slidably installed inside the guide shell 20.

[0026] Specifically, during the measurement of the drawing, the foot-operated bent rod 16 causes the comb-shaped protrusion 17 to move downward and separate from the cam gear 19. The comb-shaped protrusion 17 then compresses the spring 18. At this time, the frame 3 can be rotated to rotate the placement plate 4, so as to adjust the tilt angle of the placement plate 4. After adjusting to the appropriate angle, the bent rod 16 is released, and the spring 18 causes the comb-shaped protrusion 17 to move upward and reset, engaging with the cam gear 19 to fix the angle. By loosening the hand-tightening bolt 21, the clamping block 22 is separated from the frame 3. The frame 3 is then moved up and down to slide within the guide shell 20, facilitating the adjustment of the height of the placement plate 4. After adjustment, the hand-tightening bolt 21 is tightened, and the clamping block 22 and the frame 3 are fixed in contact, thereby achieving the purpose of adjusting the angle and height of the drawing and enhancing the flexibility of use.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
