Description

Technical Field

[0001] The present application belongs to the technical field of municipal engineering cost estimation, and in particular, relates to a cost estimation toolbox based on municipal engineering cost. Background Art

[0002] Municipal engineering is a planning and construction project for urban areas and towns, which generally belongs to national infrastructure and various public transportation facilities in urban construction. From large projects such as railways, roads, bridges, subways and river dams to small projects such as urban pipelines, water supply, natural gas and squares, municipal engineering directly affects the improvement of people's quality of life and is also related to the sustainable development of the urban economy. In order to accurately estimate the amount required for municipal engineering, it is usually necessary to use drawing comparison and on-site measurement to roughly estimate the data to ensure that the cost of municipal engineering is within an acceptable range.

[0003] The utility model with the existing authorization announcement number CN213197476U discloses a tool box for municipal engineering cost estimation, including a box body with multiple storage drawers inside; it also includes a base, with universal wheels installed at the four corners of the bottom surface of the base, and a support plate movably installed on the top surface of the base, and a support suction cup is provided on the top surface of the support plate.

[0004] The above technical scheme is easy to move, and different storage drawers are built into the box to store different cost estimation tools, which are easy to use immediately, greatly reducing the labor intensity of the estimation personnel and ensuring the reliable implementation of the project cost estimation. However, according to the above technical scheme, the cost tool box for municipal engineering cost can only be used to store cost estimation tools when in use, and cannot be used to store drawings for municipal engineering cost estimation. Since the drawings are large and cannot be folded but only rolled up to ensure the service life of the drawings, the drawings are too large to be placed inside the cost tool box. The staff needs to carry a special storage structure for the drawings, which reduces the practicality of the municipal engineering cost tool box and the adaptability of the cost estimation tool storage.

[0005] To this end, we propose a cost estimation toolbox based on municipal engineering cost estimation to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4A cost estimation toolbox based on municipal engineering cost estimation includes a box body 1. Two storage tubes 2 are arranged inside the box body 1. The top of each storage tube 2 passes through the box body 1 and extends to the top of the box body 1. An armrest 11 is fixedly connected to the back of the box body 1. Four universal wheels 12 are fixedly connected to the bottom of the box body 1. The armrest 11 cooperates with the universal wheels 12 to facilitate the staff to move the device, so that the device can be conveniently moved to the required position for cost estimation as needed, thereby improving the convenience of moving the device.

[0026] A cover plate 3 is provided on the top of each storage tube 2, and a base 4 is slidably connected to the inside of each storage tube 2. The outer surfaces of the two storage tubes 2 are commonly fixedly connected to a reinforcement frame 13, and the outer surface of each reinforcement frame 13 is fixedly connected to the inner wall of the box body 1. The reinforcement frame 13 can fix the position of the storage tube 2 inside the box body 1, making the connection between the storage tube 2 and the box body 1 more stable, thereby increasing the safety of the storage tube 2.

[0027] Three connecting plates 5 are fixedly connected to the upper surface of each base 4, and a limiting rod 14 is fixedly connected to the inner bottom wall of each storage tube 2. The inner wall of each base 4 contacts the outer surface of the limiting rod 14, and the top of each limiting rod 14 is fixedly connected to a limiting ring 15. The limiting rod 14 can assist the base 4 to slide up and down inside the storage tube 2, and the limiting ring 15 can limit the upward sliding position of the base 4 to prevent the base 4 from loosening from the storage tube 2.

[0028] The upper surface of each connecting plate 5 is fixedly connected to the bottom surface of the cover plate 3, and the outer surface of each connecting plate 5 is fixedly connected to four rubber clamping rings 6. The bottom surface of each cover plate 3 is fixedly connected to a sealing ring 16, and the outer surface of each sealing ring 16 contacts the inner wall of the storage tube 2. The upper surface of each cover plate 3 is fixedly connected to a handle 17. The sealing ring 16 can close the gap between the cover plate 3 and the storage tube 2 to prevent external dust and impurities from entering the interior of the storage tube 2, so that dust and impurities are not easy to contaminate the internal drawings of the storage tube 2. The handle 17 can facilitate the staff to manually lift the cover plate 3.

[0029] There are five drawers 7 slidably connected inside the box 1. The left side of each drawer 7 passes through the box 1 and extends to the left side of the box 1. Two limit bars 18 are arranged under each drawer 7. The side of each set of limit bars 18 that are away from each other are fixedly connected to the inner wall of the box 1. The limit bars 18 can limit the position of the drawer 7, so that the drawer 7 can slide left and right smoothly inside the box 1, thereby improving the stability of the drawer 7 during use.

[0030] A U-shaped frame 8 is slidably connected to the inside of the box 1, and three limit frames 9 are fixedly connected to the inner wall of the U-shaped frame 8. Two auxiliary plates 19 are arranged on the left and right sides of the U-shaped frame 8. The side surfaces of the two groups of auxiliary plates 19 that are away from each other are fixedly connected to the inner top wall and the inner bottom wall of the box 1 respectively. The auxiliary plates 19 can assist the U-shaped frame 8 to slide back and forth inside the box 1, so that the U-shaped frame 8 is not prone to excessive deviation, thereby increasing the reliability of the use of the U-shaped frame 8.

[0031] A plurality of limit grooves 10 are provided on the upper surface of each limit frame 9, a first handle 20 is fixedly connected to the left side of each drawer 7, and a second handle 21 is fixedly connected to the front of the U-shaped frame 8. The first handle 20 can facilitate the staff to manually open the drawer 7 and take out the tools for municipal engineering cost estimation inside, and the second handle 21 can facilitate the staff to pull the U-shaped frame 8 outward, thereby increasing the convenience of manual operation of the U-shaped frame 8.

[0032] The working principle of the utility model is as follows: when in use, the handrail 11 is first used in conjunction with the universal wheel 12 to move the device to the required position for cost estimation. At this time, the drawings for municipal engineering cost estimation rolled into a tube can be clamped through the elastic force of the rubber clamp ring 6 in conjunction with the connecting plate 5. When the drawings are needed, the connecting plate 5 can be pulled upward by the handle 17 in conjunction with the cover plate 3. At this time, the drawings clamped on the rubber clamp ring 6 can be lifted up from the storage tube 2 with the assistance of the limit rod 14 and the limit ring 15 in conjunction with the base 4, so that the cost estimation tool box for municipal engineering cost can safely and reliably store multiple municipal engineering cost estimation drawings, without the need for staff to carry a separate drawing storage structure, thereby increasing the practicality of the municipal engineering cost estimation tool box. In addition, by sliding the drawer 7 in cooperation with the first handle 20 and the limit bar 18 inside the box 1, the staff can smoothly place other municipal engineering cost estimation tools, such as calculators, notebooks, paper and pens, etc., and by using the U-shaped frame 8 in cooperation with the limit frame 9 and the limit groove 10, long strips of municipal engineering cost estimation tools, such as rulers and levels, can be conveniently placed inside the box 1, further increasing the tool storage diversity of the municipal engineering cost estimation tool box, so that the municipal engineering cost estimation tool box can store different tools as needed, making the cost tool box more adaptable to storage. When the tools inside the U-shaped frame 8 need to be used, only the second handle 21 needs to be manually pulled to pull the U-shaped frame 8 forward with the help of the auxiliary plate 19.
