[0002] Engineering cost surveying equipment is used to quickly and accurately collect on-site spatial data, acquiring geometric information such as building dimensions through laser, imaging, or 3D scanning. It is directly linked to cost data, providing objective evidence for quantity calculation, cost estimation, and review, significantly improving measurement efficiency and accuracy, reducing human error, assisting cost management, and effectively controlling project investment.

[0003] Existing surveying devices, when used on slopes or stepped terrain, typically require multiple adjustments using brick shims of appropriate height or individually adjustable supports before proceeding to the next surveying step. This process is extremely cumbersome and troublesome. Furthermore, when moving the surveying device to the next location after surveying the outer wall, it is usually transported as a whole, which can easily lead to collisions during transport. Due to the simple structure of the surveying device and the lack of protective measures, the lifespan of the equipment is affected, failing to meet usage requirements. Therefore, a field surveying device for engineering cost estimation is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a field surveying device for engineering cost estimation, which aims to improve the problems of cumbersome and troublesome adjustment of the stabilizing support for special terrain and the easy damage to the surveying instrument during transportation in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a field surveying device for engineering cost estimation, including a surveying instrument, a fixing plate detachably connected to the bottom outer wall of the surveying instrument, a hinge block fixedly connected to the bottom outer wall of the fixing plate, a stabilizing mechanism provided on the outer wall of the hinge block, and a protective mechanism provided on the inner wall of the fixing plate.

[0006] The stabilizing mechanism includes a support rod hinged to the outer wall of a hinge block. A threaded rod is threaded to the inner wall of the support rod.

A fixed block is fixedly connected to the outer wall of the sliding sleeve. A fixed cone is fixedly connected to the inner wall of the fixed block. A sliding rod is slidably connected to the inner wall of the sliding sleeve by a first spring.

[0007] As a further description of the above technical solution: the protection mechanism includes a protective rod, which is slidably connected to the inner wall of the fixed plate. A limit block is fixedly connected to the outer wall of the top end of the protective rod, and a base plate is fixedly connected to the outer wall of the bottom end of the protective rod. An inclined rod is slidably connected to the inner wall of the hinge block, and the inclined rod is elastically connected to the inner wall of the hinge block by a second spring.

[0008] As a further description of the above technical solution: the threaded rod is in contact with the outer wall of the fixed rod.

[0009] As a further description of the above technical solution: the inner wall of the fixed rod is provided with a slot, and the sliding rod is engaged in the slot on the inner wall of the fixed rod.

[0010] As a further description of the above technical solution: one end of the first spring is fixedly connected to the inner wall of the sliding rod, and the other end of the first spring is fixedly connected to the inner wall of the sliding sleeve.

[0011] As a further description of the above technical solution: the bottom outer wall of the limiting block is in contact with the top outer wall of the fixing plate.

The fixed rod is adjusted to a suitable position, and the threaded rod is rotated again to fix and lock the fixed rod. The sliding rod on the fixed rod that is suspended on one side is pulled out of the sliding sleeve. Then, the sliding sleeve is adjusted to drive the fixed cone to the place closest to the ground. The sliding rod is then put into the slot of the fixed rod to fix the sliding sleeve. The threaded rod is rotated again to release the locking fixation of the fixed rod. The fixed rod is then lowered so that the fixed cone contacts the ground. This improves the problem of the cumbersome and troublesome adjustment of the stabilizing bracket for special terrain in the prior art.

[0023] 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.

[0024] Reference Figure 1 As shown, one embodiment of this utility model is provided: a field surveying device for engineering cost estimation, including a surveying instrument 1. The surveying instrument 1 can be used to quickly and accurately collect on-site spatial data to assist in engineering cost estimation. A fixing plate 2 is detachably connected to the bottom outer wall of the surveying instrument 1. The fixing plate 2 facilitates the installation and removal of the surveying instrument 1. A hinge block 4 is fixedly connected to the bottom outer wall of the fixing plate 2. The hinge block 4 is used to connect a stabilizing mechanism 3 to help stabilize the device. The stabilizing mechanism 3 is provided on the outer wall of the hinge block 4. The stabilizing mechanism 3 can help stabilize the device in some special terrains. A protective mechanism 5 is provided on the inner wall of the fixing plate 2. The protective mechanism 5 can prevent the surveying instrument 1 from being accidentally bumped when changing surveying locations.

[0025] Reference Figure 2As shown, the stabilizing mechanism 3 includes a support rod 31, which supports the surveying device to meet measurement requirements. The support rod 31 is hinged to the outer wall of the hinge block 4. A threaded rod 32 is threadedly connected to the inner wall of the support rod 31. The threaded rod 32 is used to adjust the height of the fixing rod 33 to achieve precise fixation. The fixing rod 33 is slidably connected to the inner wall of the support rod 31. The fixing rod 33 is used to fix the support rod 31 to ensure the stability of the surveying device. A sliding sleeve 34 is slidably connected to the outer wall of the fixing rod 33. When the sliding sleeve 34 slides, it can drive the fixing cone 36 to help fix the device in special terrain. A fixing block 35 is fixedly connected to the outer wall of the sleeve 34, and a fixing cone 36 is fixedly connected to the inner wall of the fixing block 35. The fixing cone 36 is used to contact or insert into the ground to enhance the stability of the surveying device. A sliding rod 37 is slidably connected to the inner wall of the sliding sleeve 34. The sliding rod 37 can fix and limit the sliding sleeve 34 by engaging with the inner wall groove of the fixing rod 33. The sliding rod 37 is elastically connected to the inner wall of the sliding sleeve 34 by a first spring 38. The first spring 38 ensures the stable connection of the sliding rod 37 to the sliding sleeve 34 and prevents the sliding rod 37 from falling off accidentally.

[0026] Reference Figures 3-4 As shown, the protective mechanism 5 includes a protective rod 52, which is used to protect the surveying instrument 1 from collision damage and external interference during transportation. The protective rod 52 is slidably connected to the inner wall of the fixed plate 2. A limit block 51 is fixedly connected to the outer wall of the top of the protective rod 52. The limit block 51 is used to limit the range of the protective rod 52's fall. A base plate 53 is fixedly connected to the outer wall of the bottom of the protective rod 52. The base plate 53 can connect the protective rods 52 so that all the protective rods 52 can move up and down synchronously. An inclined rod 54 is slidably connected to the inner wall of the hinge block 4. The inclined rod 54 can be engaged with the limit slot on the inner wall of the side of the base plate 53 to fix and limit the base plate 53. The inclined rod 54 is elastically connected to the inner wall of the hinge block 4 by a second spring 55. The second spring 55 ensures the stable connection of the inclined rod 54 to the hinge block 4 and prevents the inclined rod 54 from falling off accidentally.

[0027] In use, the device is first initially stabilized by unfolding the support rod 31. Then, the threaded rod 32 is rotated to release the fixation of the fixed rod 33. The fixed rod 33 is adjusted to a suitable position, and the threaded rod 32 is rotated again to lock the fixed rod 33. The sliding rod 37 on the fixed rod 33, which is suspended on one side, is pulled out of the sliding sleeve 34. The sliding sleeve 34 is then adjusted to move the fixed cone 36 to the closest point to the ground. The sliding rod 37 is then inserted into the slot of the fixed rod 33 to fix the sliding sleeve 34. The threaded rod 32 is rotated again to release the lock on the fixed rod 33. The fixed rod 33 is then lowered so that the fixed cone 36 contacts the ground, thus completing the fixed placement of the device on special terrain.

[0028] When it is necessary to change the surveying location, the base plate 53 is raised upward, which drives the protective rod 52 to move upward until the limiting slot on the side of the base plate 53 engages with the inclined rod 54, thus completing the protection of the surveying instrument 1; when the location is reached and the protection is released, the inclined rod 54 is pulled to release the engagement with the limiting slot on the side of the base plate 53, and the base plate 53 falls down until the limiting block 51 contacts the top outer wall of the fixed plate 2, thus completing the release of the protection of the surveying instrument 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
