Description

Technical Field

[0001] This utility model belongs to the field of construction engineering cost technology, specifically a portable construction engineering cost testing instrument. Background Technology

[0002] Construction cost estimation is the process of determining and controlling all expenses required for the construction of a construction project. It covers all stages from project planning, design, construction to final acceptance. It involves accurate estimation and accounting of various expenditures such as labor, materials, equipment, and management fees to ensure reasonable investment and economic efficiency. It is one of the key factors for the successful implementation of a construction project.

[0003] In order to ensure the timeliness and accuracy of data during the construction cost estimation process, a portable construction cost estimation tester is used. Due to the complexity of construction sites, operators often need to park the tester on slopes during testing. Although existing portable construction cost estimation testers can facilitate movement, they cannot guarantee the stability of the tester when parked on slopes, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a mobile building construction cost testing instrument with the advantage of stable stationary operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable building construction cost testing instrument, comprising a base plate, on which movable wheels are movably installed on both the left and right sides of the front and back sides of the base plate; a handrail is fixedly installed on the left side of the top of the base plate; vertical rods are movably sleeved at the four corners inside the base plate; anti-slip pads are fixedly installed at the bottom of the vertical rods; mounting blocks are fixedly connected to the top of the vertical rods; connecting rods are fixedly sleeved between the mounting blocks; a double-threaded rod is movably sleeved inside the base plate; and the front and rear sides of the outer surface of the double-threaded rod... Each side is threaded with a movable plate, the outer surface of which is movably connected to the inner surface of the base plate. There are two movable plates, and each movable plate has a hinge rod hinged to its left and right sides. The other end of each hinge rod is hinged to a movable block. The bottom of each movable block is fixedly connected to a limit block, the outer surface of which is movably connected to the inner wall of the base plate. The movable block has an inclined groove inside, the inner surface of which is movably connected to the outer surface of a connecting rod. A handle located on the front of the base plate is fixedly sleeved on the front side of the outer surface of the double-threaded rod.

[0006] As a preferred embodiment of this utility model, a housing is fixedly installed on the top of the base plate, a base is fixedly installed on the top of the housing, and the tester body is fixedly installed on the top of the base.

[0007] As a preferred embodiment of this invention, a protective cover is movably mounted on the top of the housing, and a sliding groove is provided on the top of the housing.

[0008] As a preferred embodiment of this invention, a slider located inside a groove is fixedly installed at the bottom of the protective cover, and a round block is fixedly connected to the bottom of the slider.

[0009] As a preferred embodiment of this utility model, crossbars are fixedly installed on both the front and rear sides inside the housing, and movable plates are movably sleeved on both the left and right sides of the outer surface of the crossbars. A fixed frame is fixedly connected to the top of the movable plate, and the inner surface of the fixed frame is movably connected to the outer surface of the circular block.

[0010] As a preferred embodiment of this utility model, a motor is fixedly installed on the top of the inner surface of the housing, and a rotating shaft is fixedly connected to the other end of the motor output shaft, with a rotating rod fixedly sleeved on the outer surface of the rotating shaft.

[0011] As a preferred embodiment of this invention, push-pull rods are hinged to both the left and right ends of the rotating rod, and the other end of the push-pull rod is hinged to the inner side of the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a vertical rod, a connecting rod, a moving block, and an inclined groove, allows the operator to rotate the handle when the base plate is positioned on the slope. This rotation causes the handle to rotate the double threaded rod, which in turn causes the two moving plates to move in opposite directions. This, in turn, causes the hinged rod to push the two moving blocks to move in opposite directions. Consequently, the inner surface of the inclined groove presses against and pushes the connecting rod downwards. The connecting rod then causes the vertical rod and the anti-slip pad to move downwards, allowing the anti-slip pad to contact the ground. This provides stable support for the entire base plate, making the base plate more stable when placed.

[0014] 2. This utility model, by setting up protective covers, movable plates, motors, and slides, allows the operator to start the motor after completing the test using the main body of the tester. This causes the rotating shaft to rotate, which in turn causes the push-pull rod to pull the two movable plates to move in opposite directions. The movable plates then cause the fixed frame to move, and the inner surface of the fixed frame will press and push the circular block to move. This causes the circular block to move the slider along the inner surface of the slide, thereby causing the four protective covers to close, thus protecting the main body of the tester.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a portable building construction cost testing instrument, including a base plate 1. Movable wheels 2 are movably installed on the left and right sides of the front and back of the base plate 1. A handrail 3 is fixedly installed on the left side of the top of the base plate 1. Vertical rods 4 are movably sleeved at the four corners inside the base plate 1. Anti-slip pads 5 are fixedly installed at the bottom of the vertical rods 4. Mounting blocks 6 are fixedly connected to the top of the vertical rods 4. Connecting rods 7 are fixedly sleeved between the mounting blocks 6. A double-threaded rod 8 is movably sleeved inside the base plate 1. Moving plates 9 are threadedly sleeved on the front and back sides of the outer surface of the double-threaded rod 8. The outer surface of the movable plate 9 is movably connected to the inner surface of the base plate 1. There are two movable plates 9. The left and right sides of the two movable plates 9 are hinged with hinge rods 10. The other end of the hinge rods 10 is hinged with a movable block 11. The bottom of the movable block 11 is fixedly connected to a limit block 14. The outer surface of the limit block 14 is movably connected to the inner wall of the base plate 1. The inside of the movable block 11 is provided with a slanted groove 12. The inner surface of the slanted groove 12 is movably connected to the outer surface of the connecting rod 7. The front side of the outer surface of the double threaded rod 8 is fixedly sleeved with a handle 13 located on the front of the base plate 1.

[0024] When the operator moves the base plate 1 to the slope or a designated location, they can rotate the handle 13 to rotate the double threaded rod 8. Since the threads on the front and back sides of the outer surface of the double threaded rod 8 are in opposite directions, the double threaded rod 8 can drive the two moving plates 9 to move towards each other. This allows the hinge rod 10 to push the two moving blocks 11 to move away from each other, thereby causing the inner surface of the inclined groove 12 to press and push the connecting rod 7 down. The connecting rod 7 will then drive the vertical rod 4 to move downward, so that the anti-slip pad 5 contacts the ground, making the base plate 1 more stable.

[0025] The base plate 1 has a housing 15 fixedly installed on the top, a base 16 fixedly installed on the top of the housing 15, and a tester body 17 fixedly installed on the top of the base 16.

[0026] As a technical optimization of this utility model, after the operator pushes the base plate 1 to the designated location, the test can be performed using the tester body 17.

[0027] The top of the housing 15 is movably fitted with a protective cover 18, and the top of the housing 15 is provided with a sliding groove 28.

[0028] As a technical optimization of this utility model, by setting up protective covers 18, the tester body 17 can be protected when the four protective covers 18 are closed.

[0029] The bottom of the protective cover 18 is fixedly installed with a slider 19 located inside the slide groove 28, and the bottom of the slider 19 is fixedly connected with a round block 20.

[0030] As a technical optimization of this utility model, when the circular block 20 moves, it will drive the slider 19 to move along the inner surface of the groove 28, thereby enabling the protective cover 18 to move.

[0031] The shell 15 has crossbars 21 fixedly installed on both the front and rear sides inside. The crossbars 21 have movable plates 22 movably sleeved on both the left and right sides of their outer surfaces. The top of the movable plates 22 is fixedly connected to a fixed frame 23, and the inner surface of the fixed frame 23 is movably connected to the outer surface of the round block 20.

[0032] As a technical optimization of this utility model, by setting a crossbar 21, the crossbar 21 can limit the movement of the movable plate 22. When the two movable plates 22 move towards each other, the fixed frame 23 will drive the circular block 20 to move.

[0033] The top of the inner surface of the housing 15 is fixedly mounted with a motor 24, the other end of the output shaft of the motor 24 is fixedly connected to a rotating shaft 25, and a rotating rod 26 is fixedly sleeved on the outer surface of the rotating shaft 25.

[0034] As a technical optimization of this utility model, the operator can start the motor 24 so that the rotating shaft 25 can drive the rotating rod 26 to rotate.

[0035] The rotating rod 26 has push-pull rods 27 hinged to both its left and right ends, and the other end of the push-pull rods 27 is hinged to the inner side of the movable plate 22.

[0036] As a technical optimization of this utility model, when the rotating rod 26 rotates, it will drive the two movable plates 22 to move in opposite directions through the push-pull rod 27.

[0037] Working principle and usage process of this utility model:

[0038] The operator can push the base plate 1 to the testing location using the handle 3. When the base plate 1 is moved onto the slope, the operator can rotate the handle 13 to rotate the double threaded rod 8. This causes the double threaded rod 8 to move the two moving plates 9 towards each other. The hinge rod 10 then pushes the two moving blocks 11 towards each other under the limiting action of the limiting block 14. This causes the inner surface of the inclined groove 12 to press against the outer surface of the connecting rod 7, causing the connecting rod 7 to move downwards. This, in turn, causes the vertical rod 4 to move downwards, ultimately making the anti-slip pad 5 contact the ground. This provides stable support for the base plate 1, allowing it to be placed more stably.

[0039] After the test is completed, the motor 24 is started, which causes the rotating shaft 25 to drive the rotating rod 26 to rotate. This causes the two movable plates 22 to move towards each other under the limiting action of the crossbar 21 via the push-pull rod 27. The movable plates 22 then drive the fixed frame 23 to move towards each other. The inner surface of the fixed frame 23 will squeeze and push the round block 20, causing the round block 20 to drive the slider 19 to move along the inner surface of the slide groove 28. This causes the four protective covers 18 to close, which can protect the tester body 17.
