Description

Technical Field

[0001] The utility model relates to a construction engineering cost on-site surveying and mapping device. Background Art

[0002] The construction cost generally refers to the cost of carrying out a certain project construction, that is, all the costs from preparation to completion and acceptance. It consists of construction and installation engineering costs, equipment and tools purchase costs, other construction costs and contingency costs and taxes. In the process of construction project cost calculation, it is sometimes necessary to survey the site, and when conducting on-site surveying and mapping, surveying and mapping devices are often used.

[0003] Among the existing utility models in China, the publication number CN219263820U discloses a construction engineering cost on-site surveying and mapping device, wherein three groups of fixed blocks with the same structure are arranged in a triangular structure at the bottom of the support plate, a connecting pipe is arranged at the bottom of the fixed block, a leg sleeve is arranged at the bottom of the connecting pipe, a fastening device is arranged at the bottom outer wall of the leg sleeve, a sliding rod is movably connected to the bottom of the leg sleeve, a foot support is arranged at the bottom of the sliding rod, a rotating groove is opened at the top central axis position of the support plate, a bottom plate is arranged at the upper end of the support plate, a rotating column is arranged at the bottom of the bottom plate, the rotating column is arranged in the rotating groove, and a surveying and mapping instrument is arranged at the top of the bottom plate, which is convenient for fixing the overall device, and can also achieve horizontal fixation by adjusting the sliding rod and the fastening device for uneven terrain, and different angles can be measured by rotating the bearing shaft even without moving the device, which saves the time for adjusting the instrument.

[0004] Referring to the above-mentioned construction engineering cost on-site surveying and mapping device, the footrest at the bottom of the surveying and mapping device is in a pointed cone shape, and its supporting surface is relatively small.

Therefore, how to make the surveying and mapping device better supported on the soft ground is an important problem that needs to be solved in the design of the construction engineering cost on-site surveying and mapping device. Utility Model Content

[0005] The utility model provides a construction engineering cost on-site surveying and mapping device to solve the problem of enabling the surveying and mapping device to be better supported on soft ground.

[0018] Preferably, snap-fit ​​grooves are provided at equal distances on the side walls of the rotating block.

[0019] Preferably, the clamping structure includes a sliding frame, a sliding block, a spring, a clamping rod and a sliding rod, the sliding block is fixedly connected to the inner side wall of the sliding frame, the sliding frame is slidably connected to the side wall of the support rod, the sliding block is slidably connected in the sliding groove, the sliding rod is fixedly connected to the inner side wall of the sliding groove, the sliding rod and the sliding block are slidably connected, a spring is fixedly connected between the sliding block and the sliding groove, two clamping rods are fixedly connected to the bottom side wall of the sliding frame, and the clamping rods and the clamping groove cooperate with each other.

[0021] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0022] The positive and progressive effects of the utility model are:

[0023] 1. By rotating the support plate to be parallel to the ground, the contact area between the support plate and the ground support can be increased, thereby increasing the support surface at the bottom end of the support rod, making it easier for the support rod to be better supported on the soft ground, thereby preventing the support rod from sinking into the soft ground, resulting in unstable placement of the construction project cost site surveying and mapping device.

[0024] 2. By clamping the clamping rod in the clamping groove, the rotating block can be restricted, thereby better restricting the column support plate to avoid the support plate from rotating during the support process, resulting in failure to provide better support for the on-site surveying and mapping device of the engineering cost.

[0032] like Figure 1-4 As shown, a construction engineering cost on-site surveying and mapping device includes a construction engineering cost surveying and mapping instrument 1, and also includes:

[0033] A support structure 2, wherein the support structure 2 is arranged at the bottom of the construction engineering cost surveying and mapping instrument 1;

[0035] The clamping structure 3 is arranged above the rotating structure 4 , and the clamping structure 3 is used to fix and restrict the rotating structure 4 .

[0036] The support structure 2 includes a support base 201, a support rod 202 and a support foot 203.

The two ends of the bottom side wall of the support rod 202 are fixedly connected with support feet 203, and the bottom of the support foot 203 is in a pointed cone shape.

[0037] By opening the support rod 202 and supporting the support foot 203 on the ground, the support base 201 can be well supported, thereby well supporting the construction engineering cost surveying and mapping instrument 1.

[0038] The side wall of the support rod 202 is provided with a first rotation groove 221 , a sliding groove 222 and a second rotation groove 223 , and the first rotation groove 221 and the second rotation groove 223 are connected to each other.

[0039] The support structure 2 includes a support plate 211, a rotating connection block 212 and a rotating tooth groove 213. The rotating connection block 212 is rotatably connected in the side wall of the rotating groove 221. The side wall of the rotating connection block 212 is fixedly connected to the support plate 211. The width of the support plate 211 matches the width of the rotating groove 221. The side wall of the rotating connection block 212 is provided with a rotating tooth groove 213.

[0040] The rotating connecting block 212 drives the support plate 211 to rotate, and the support plate 211 is rotated between the two supporting feet 203 on the support rod 202, so that the support plate 211 is as parallel to the ground as possible. When the support plate 211 is rotated to be parallel to the ground, the contact area between the support plate 211 and the ground support can be increased, and the supporting surface at the bottom end of the support rod 202 can be increased, so that the support rod 202 is better supported on the soft ground, avoiding the support rod 202 from sinking into the soft ground, which makes it difficult for the construction project cost on-site surveying and mapping device to stand firmly.

[0041] The rotating structure 4 includes a rotating block 401, a rotating rod 402 and a rotating gear 403. The rotating rod 402 is rotatably connected to the side wall of the support rod 202. The rotating rod 402 passes through the second rotating groove 223. The rotating gear 403 is fixedly connected to the side wall of the rotating rod 402. The rotating gear 403 is located in the second rotating groove 223. The rotating gear 403 and the rotating tooth groove 213 are meshed with each other. Both ends of the rotating rod 402 are fixedly connected to the rotating block 401.

[0042] The rotating block 401 is rotated, and the rotating block 401 drives the rotating rod 402 to rotate. The rotating rod 402 drives the rotating gear 403 to rotate. The rotating gear 403 rotates in the rotating tooth groove 213 to drive the rotating connecting block 212 to rotate.

[0043] The side wall of the rotating block 401 is provided with snap-fitting grooves 5 at equal intervals.

[0044] The clamping structure 3 includes a sliding frame 301, a sliding block 302, a spring 303, a clamping rod 304 and a sliding rod 305.

Two clamping rods 304 are fixedly connected to the bottom side wall of the sliding frame 301. The clamping rod 304 and the clamping groove 5 cooperate with each other.

[0045] Lift the sliding frame 301 upwards, and the sliding frame 301 drives the sliding block 302 and the locking rod 304 to move, so that the locking rod 304 leaves the locking groove 5, and release the sliding frame 301. The compressed spring 303 expands and pushes the sliding frame 301 to descend, so that the locking rod 304 is re-engaged into the corresponding locking groove 5, restricting the rotating block 401, thereby better restricting the column support plate 211.

[0046] When the utility model is in use, the electrical components appearing in the present application are all externally connected to a power supply and a control switch. When the construction engineering cost surveying and mapping device is placed on a soft ground for surveying and mapping, the sliding frame 301 can be lifted upward, and the sliding frame 301 drives the sliding block 302 and the clamping rod 304 to move, so that the clamping rod 304 leaves the clamping groove 5, and the rotating block 401 is rotated, and the rotating block 401 drives the rotating rod 402 to rotate, and the rotating rod 402 drives the rotating gear 403 to rotate, and the rotating gear 403 rotates in the rotating tooth groove 213 to drive the rotating connecting block 212 to rotate, and the rotating connecting block 212 drives the supporting plate 211 to rotate, and the supporting plate 211 is rotated between the two supporting feet 203 on the supporting rod 202, and then the supporting rod 201 is opened, and the supporting feet 203 are inserted into the soft ground;

[0047] After the adjustment, the sliding frame 301 is released, and the compressed spring 303 is expanded to push the sliding frame 301 down, so that the clamping rod 304 is clamped into the corresponding clamping groove 5 again, and the rotating block 401 is restricted, thereby better restricting the column support plate 211. If the clamping rod 304 is not clamped into the clamping groove 5, it is only necessary to slightly rotate the rotating block 401 left and right for adjustment, and the clamping rod 304 will be clamped into the nearest clamping groove 5. When the support plate 211 is rotated to be parallel to the ground, the contact area between the support plate 211 and the ground support can be increased, and the supporting surface of the bottom end of the support rod 202 can be increased, so that the support rod 202 is better supported on the soft ground, avoiding the support rod 202 from sinking into the soft ground, resulting in the unstable placement of the construction project cost on-site surveying and mapping device.
