Therefore, they cannot be understood as limitations on the present invention.

[0027] In this utility model, unless otherwise expressly defined, terms such as "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection; internal communication between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of these terms in this utility model based on the specific content of the technical solution.

[0028] Reference Figures 1 to 3 The embodiment of the present invention is a rolling ruler tool for engineering cost estimation, which includes a mounting frame 100, a small wheel component 200, a large wheel component 300 and a handle assembly 400.

[0029] A recorder 500 is provided on the top side of the mounting frame 100. The small wheel component 200 is connected to the rotating shaft of the recorder 500 and is located on the left side of the mounting frame 100. The large wheel component 300 is detachably mounted on the small wheel component 200. The hand lever assembly 400 is provided on the mounting frame 100.

[0030] It is understood that the lateral projection area of ​​the large wheel 300 is larger than the lateral projection area of ​​the small wheel 200, and the lateral projection area of ​​the small wheel 200 is larger than the sum of the lateral projection areas of the mounting bracket 100 and the recorder 500. The above lateral projection is projected from left to right.

[0031] It is understandable that, referring to Figure 1 The recorder 500 is provided with two buttons for switching between a first recording mode and a second recording mode, wherein the first recording mode corresponds to measurement of the small wheel 200 and the second recording mode corresponds to measurement of the large wheel 300.

[0032] When the surveyor chooses to use the small wheel member 200 for measurement according to the road conditions, the surveyor can detach the large wheel member 300 mounted on the small wheel member 200 to push the hand lever assembly 400 to drive the small wheel member 200 to roll on the road surface, so that the recorder 500 in the first recording mode can obtain and record the corresponding travel data.

[0033] When the surveyor chooses to use the large wheel 300 for measurement according to the road conditions, the surveyor can re-install the large wheel 300 on the small wheel 200 to push the hand lever assembly 400 to drive the large wheel 300 to roll on the road surface, so that the recorder 500 can obtain and record the corresponding travel data in the second recording mode.

[0034] It is understandable that when the large wheel 300 is re-mounted on the small wheel 200 and rolls on the road, the rolling large wheel 300 drives the small wheel 200 to roll, thereby driving the rotating shaft on the recorder 500 to rotate to generate corresponding travel data.

[0035] Through the above structure, on the one hand, the roller measure tool for engineering cost of the present application can achieve the measurement effect of both the large wheelbase measuring wheel and the small wheelbase measuring wheel; on the other hand, when the surveyor carries the roller measure tool for engineering cost of the present application, it can reduce the physical burden of the surveyor compared to the traditional method of carrying two measuring wheels at the same time, thereby reducing the labor intensity of the surveyor.

[0036] The large wheel 300 is detachably mounted on the small wheel 200. Figure 1 and Figure 2 The small wheel assembly 200 includes a first inner frame portion 210 and a first outer ring portion 220 connected to each other. The large wheel assembly 300 includes a second inner frame portion 310 and a second outer ring portion 320 connected to each other. The first outer ring portion 220 and the second outer ring portion 320 are both configured for rolling contact with the road surface. The second inner frame portion 310 has a fitting groove 311, and a connecting post 311A ​​is provided at the bottom of the fitting groove 311. The first inner frame portion 210 has a connecting hole 211. The second inner frame portion 310 is fitted onto the first outer ring portion 220 through the fitting groove 311. The connecting post 311A ​​is inserted into the connecting hole 211. A first fastener is threadedly connected to the connecting post 311A. The bottom of the fitting groove 311 and the first fastener jointly clamp the first inner frame portion 210. The first fastener can be a nut or the like.

[0037] In some embodiments, the connection hole 211 may be disposed at the bottom of the fitting groove 311 , and the connection column 311A ​​may be disposed at the first inner frame portion 210 .

[0038] In order to improve the connection stability between the large wheel 300 and the small wheel 200, refer to Figure 1 and Figure 2 The number of the connecting posts 311A ​​and the number of the connecting holes 211 are both set to three, and the three connecting posts 311A ​​are inserted into the three connecting holes 211 in a one-to-one correspondence.

[0039] It can be understood that the three connecting columns 311A ​​are inserted into the three connecting holes 211 in a one-to-one correspondence, which can better position the large wheel component 300 and the small wheel component 200.

[0040] The hand lever assembly 400 includes a first lever 410 , a second lever 420 and a handle 430 .

[0041] Reference Figure 1 and 2 One end of the first rod 410 is detachably disposed on the top side of the mounting bracket 100 , one end of the second rod 420 is detachably disposed on the other end of the first rod 410 , and the handle 430 is disposed on the other end of the second rod 420 .

[0042] It is understandable that the surveyor can hold the handle 430 and move the first rod 410 and the second rod 420 to drive the small wheel 200 or the large wheel 300 to roll on the road surface.

[0043] Through the above structure, the first rod 410 can be detached from the mounting frame 100, and the second rod 420 can be detached from the first rod 410, so as to reduce the space occupied by the roller ruler tool of the present application during transportation and reduce the transportation cost.

[0044] One end of the second rod 420 is detachably mounted on the other end of the first rod 410. Figure 2 The other end of the first rod 410 is provided with four locking holes 411, and the four locking holes 411 are arranged in sequence along the length direction of the first rod 410. One end of the second rod 420 is provided with a compressible and resilient locking block 421. One end of the second rod 420 can be slidably and telescopically inserted into the other end of the first rod 410, and the locking block 421 is passed through a corresponding locking hole 411.

[0045] Through the above structure, on the one hand, the compressible and resilient locking block 421 is inserted into the corresponding locking hole 411, which can realize the detachable connection between the second rod 420 and the first rod 410; on the other hand, the measurement personnel can adjust the compressible and resilient locking block 421 to be inserted into the corresponding locking hole 411 according to their own height, that is, adjust the corresponding length of the hand rod assembly 400 to adapt to their own height.

[0046] In this embodiment, referring to Figure 1 The mounting frame 100 is provided with a first connection notch 110 for sleeve-fixing the first rod 410 , and the first rod 410 is provided with a second connection notch 412 for sleeve-fixing the second rod 420 .

[0047] Through the above structure, when the first rod 410 is detached from the mounting bracket 100 and the second rod 420 is detached from the first rod 410, the mounting bracket 100 can be mounted on the rod portion of the first rod 410 through the first connecting notch 110, and the first rod 410 can be mounted on the rod portion of the second rod 420 through the second connecting notch 412, so as to reduce the probability of losing the first rod 410 and / or the second rod 420.

[0048] One end of the first rod 410 is detachably mounted on the top side of the mounting bracket 100. Figure 1 and Figure 3The top side of the mounting frame 100 is provided with an inserting barrel 120. The mounting frame 100 is provided with a first hole 130 that communicates with the barrel cavity of the inserting barrel 120. One end of the first rod 410 is provided with a second hole. One end of the first rod 410 is inserted into the inserting barrel 120. A second fastener is threadedly inserted through the second hole and the first hole 130. The second hole is a screw hole, the first hole 130 is a through hole, and the second fastener is a bolt.
