Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying and mapping, and particularly relates to a surveying and mapping support frame. Background Art

[0002] Engineering surveying and mapping provides precise measurement data, map materials and other services for the planning, design, construction, operation and management stages of engineering construction. When surveying and mapping, instruments such as level gauges, theodolites or total stations are usually used. In order to ensure the stability of such instruments during use, support frames are used to support the instruments.

[0003] In the existing patent literature, the patent with the publication number CN 214222499 U and the name of "a surveying and mapping support frame" has multiple support points, but there is only one supporting foot at each support point.

[0032] As Figures 1 to 4 shown, a surveying and mapping support frame includes a top placement part 1, a side support part 2, and a central strengthening part 3. The side support part 2 is movably installed at the bottom of the top placement part 1 and is distributed in a circumferential array centered on the top placement part 1. The central strengthening part 3 is fixedly installed at the bottom of the top placement part 1 and simultaneously strengthens the connection to support the side support part 2. The top placement part 1 includes a placement table 101. The side support part 2 includes a first side support arm 201 and a second side support arm 202 located below the first side support arm 201. The placement table 101, the first side support arm 201, and the second side support arm 202 are rotatably installed between each other and are provided with damping. A first foot 203 is installed at the bottom of the second side support arm 202. A storage groove 204 is formed on the rod body of the second side support arm 202. The top of the storage groove 204 is rotatably installed with a side support rod 205 and is provided with damping. A second foot 206 is installed at the bottom of the side support rod 205. The first foot 203 and the second foot 206 simultaneously support on the ground. At each support point of this surveying and mapping support frame, two feet are set at the same time. When the surveying and mapping support frame is placed on an inclined surface or an uneven surface, the surveying and mapping support frame will be more stable and reliable after being placed. Secondly, one of the feet can be stored and hidden, making it more flexible in actual application.

[0033] As Figure 4 shown, both between the second side support arm 202 and the first foot 203, and between the side support rod 205 and the second foot 206 are connected by a lead screw 207. The lead screw 207 can move up and down inside the second side support arm 202 or the side support rod 205. In order to adjust the height of the two feet, by rotating the lead screw 207, the height of the feet can be adjusted to adapt to the inclined or uneven ground.

[0034] As Figure 4 shown, the bottom ends of the first support leg 203 and the second support leg 206 are both provided with pointed ends. In order to facilitate the embedding of the support legs into the ground, the bottom ends of the support legs are tapered, and they will be more stable after being embedded into the ground.

[0035] As Figure 4 shown, at least one rotating handle 208 is fixedly installed on the side walls of the first support leg 203 and the second support leg 206. In order to facilitate the rotation of the support legs, by installing the rotating handle 208, it will be more labor-saving when rotating the support legs.

[0036] As Figure 5 shown, the central strengthening part 3 includes a central arm 301, the top end of the central arm 301 is fixedly installed at the bottom of the placement table 101 through a flange 302; a first strengthening rod 303 and a second strengthening rod 304 located below the first strengthening rod 303 are rotatably installed on the side wall of the central arm 301, and the first strengthening rod 303 and the second strengthening rod 304 respectively support on the first side support arm 201 and the second side support arm 202; a first slot 305 and a second slot 306 are respectively formed on the first side support arm 201 and the second side support arm 202 along their respective lengths, and the first strengthening rod 303 and the second strengthening rod 304 are respectively inserted into the first slot 305 and the second slot 306; two nuts 307 are respectively installed on the first strengthening rod 303 and the second strengthening rod 304, and the two nuts 307 can clamp and fix the first strengthening rod 303 on the first side support arm 201, and the two nuts 307 can clamp and fix the second strengthening rod 304 on the second side support arm 202. In order to improve the support effect of the side support arms, strengthening rods are used for support on the side support arms, and there are two nuts 307 for tightening. It has high flexibility in application and can meet the tightening of the side support arms in different states.

[0037] As Figure 6 shown, two symmetrically arranged bases 102 are fixedly connected to the upper surface of the placement table 101, a screw rod 103 extending into the center of the placement table 101 is penetrated and fitted on the bases 102, and a chuck 104 is fixed at the end of the screw rod 103; the surface of the chuck 104 is round-headed. In order to facilitate the fixation of the instrument, after placing the instrument on the placement table 101, by rotating the screw rod 103, the instrument can be clamped and fixed by two symmetrically arranged chucks 104, and it will be more stable when using the instrument.

[0038] The working principle of the present utility model:

[0039] During application, the first side support arm 201 and the second side support arm 202 are respectively rotated and adjusted to meet their use on different ground surfaces.

[0040] If it is used on a flat surface, at this time the center of gravity is located at the center, and only the supporting leg 203 can be used for support at each supporting point. Subsequently, a reinforcing rod is used for support on the side support arm, and there are two nuts 307 for fastening to strengthen the support.

[0041] If it is used on an inclined or uneven surface, at this time the center of gravity will shift. In order to stabilize the support effect, after rotating the side support rod 205, the supporting leg 206 is used for additional support. At this time, each supporting point is supported by two supporting legs at the same time, and the surveying and mapping support frame will be more stable and reliable after being placed.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
