Description

A surveying and mapping device for urban planning Technical Field

[0001] This utility model relates to the field of urban planning technology, and in particular to a surveying and mapping device for urban planning. Background Technology

[0002] Urban planning is a comprehensive plan that regulates urban development and construction, studies the future development of the city, the rational layout of the city, and the comprehensive arrangement of various urban construction projects. It is a blueprint for urban development within a certain period and an important part of urban management. Surveying equipment is frequently used in urban planning and construction.

[0003] Currently, surveying equipment on the market is usually equipped with a tripod for support. However, most existing tripods are inconvenient to move. When changing the surveying position, the equipment needs to be lifted and moved manually, which is quite laborious. While some existing tripods are equipped with wheels, these wheels are usually independently mounted on the tripod legs and switched between legs. Therefore, before moving the equipment, the user needs to spend a lot of time adjusting each wheel individually, which is quite troublesome.

[0004] Therefore, we propose a surveying and mapping device for urban planning to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a surveying and mapping device for urban planning, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A surveying and mapping device for urban planning includes a surveying and mapping device body and a tripod. The tripod consists of a mounting plate and three support rods hinged around the circumference of the mounting plate. An adjusting rod is connected to the center of the mounting plate. A threaded sleeve is screwed onto the adjusting rod, and a swivel ring is rotatably mounted outside the threaded sleeve. A support rod is hinged to each support rod corresponding to the swivel ring. A chassis is mounted below the adjusting rod via a telescopic rod. Three casters are evenly distributed around the lower surface of the chassis. A slot is provided on the outer periphery of the chassis corresponding to each support rod for locking and limiting the support rod.

[0008] In a further embodiment, the telescopic rod includes a sleeve and a core rod that are sleeved together. A pair of positioning grooves are provided on the outer side walls of the sleeve near both ends. A positioning block is engaged in the positioning groove and is radially slidably connected to the core rod. A metal spring is installed at one end of the positioning block that extends into the core rod.

[0009] In a further embodiment, the positioning block consists of a T-shaped rod and rotating wheels rotatably mounted at both ends of the crossbar of the T-shaped rod.

[0010] In a further embodiment, the adjusting rod is provided with a connecting flange at one end near the sleeve, and the adjusting rod and the sleeve are locked together by multiple bolts.

[0011] In a further embodiment, the lower end of the sleeve is screwed with an end cap, and the core rod slides through the interior of the end cap.

[0012] In a further embodiment, the bottom end of the core rod is threadedly connected to the chassis.

[0013] In a further embodiment, the casters and slots are arranged in an alternating pattern.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In its normal state, the telescopic rod is in a shortened state, with the chassis higher than the bottom of the support rod, which does not affect the normal deployment and support operation of the support rod. At the same time, the slot can be used to limit the retracted support rod, making it less likely to spread out. When it is necessary to move the equipment, simply extend the telescopic rod so that the casters are lower than the bottom of the support rod, and the caster support can be switched, making it more convenient and faster to change the surveying position of the equipment.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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] Please refer to Figures 1-2. A surveying device for urban planning includes a surveying device body 1 and a tripod. The tripod consists of a mounting plate 2 and three support rods 3 hinged around the circumference of the mounting plate 2. The surveying device body 1 is mounted on the mounting plate 2. An adjusting rod 4 is connected to the lower center of the mounting plate 2. The adjusting rod 4 is a threaded rod, and a threaded sleeve 5 is screwed onto the external thread of the adjusting rod 4. A rotating ring 6 is rotatably mounted on the outside of the threaded sleeve 5. A support rod 7 is hinged to each support rod 3 on the outside of the rotating ring 6. The end of the support rod 7 away from the rotating ring 6 is hinged to the inner wall of the support rod 3, so that when the threaded sleeve 5 is rotated, the threaded sleeve 5 rotates within the rotating ring 6 and screws upward or downward along the adjusting rod 4. When the threaded sleeve 5 screws upward, it drives the support rod 7 to support the support rod 3; conversely, when the threaded sleeve screws downward, the support rod 7 screws upward. When the 5-axis rotates downwards, it drives the support rod 7 to pull the support rod 3 to retract. The chassis 9 is installed under the adjusting rod 4 via the telescopic rod 8. Three universal wheels 10 are evenly distributed around the lower surface of the chassis 9. Each support rod 3 has a slot 11 on its outer periphery for the support rod 3 to be engaged and limited. Specifically, the universal wheels 10 and the slots 11 are arranged alternately to avoid mutual interference. Under normal conditions, the telescopic rod 8 is in a shortened state, and the chassis 9 is higher than the bottom of the support rod 3, which does not affect the normal deployment and support operation of the support rod 3. When it is necessary to move the equipment, simply pull down the telescopic rod 8 so that the universal wheels 10 are lower than the bottom of the support rod 3, and the support of the universal wheels 10 can be switched, making it more convenient and faster to change the surveying position of the equipment.

[0025] Please refer to Figures 3-4. To facilitate the telescopic adjustment of the telescopic rod 8, the telescopic rod 8 includes a sleeve 81 and a core rod 82 that are nested together. The sleeve 81 is slidably fitted onto the outside of the core rod 82. A pair of positioning grooves 83 are provided on the outer side wall of the sleeve 81 near its axial ends. Positioning blocks 84 are engaged in the positioning grooves 83, and the positioning blocks 84 are radially slidably connected to the core rod 82. A metal spring piece 85 is installed at one end of the positioning block 84 that extends into the core rod 82. When the positioning block 84 is pressed into the gap between the sleeve 81 and the core rod 82, the core rod 82 can be pulled to extend or retract relative to the sleeve 81. When the positioning block 84 is engaged in the upper positioning groove 83, the telescopic rod 8 is in a shortened state, and when the positioning block 84 is engaged in the lower positioning groove 83, the telescopic rod 8 is in an extended state. In actual operation, you only need to press the positioning block 84 into the positioning groove 83 by hand and then step down on the base plate 9 to extend the telescopic rod 8. The operation is convenient.

[0026] Furthermore, the positioning block 84 consists of a T-shaped rod 841 and rotating wheels 842 rotatably mounted at both ends of the crossbar of the T-shaped rod 841. When the telescopic rod 8 is extended or retracted, the rotating wheels 842 can roll on the inner wall of the sleeve 81, thereby reducing the frictional resistance of extension and retraction. At the same time, the inner wall of the sleeve 81 is provided with grooves for the rotating wheels 842 to roll, which facilitates the limiting of the rotating wheels 842 and prevents the sleeve 81 and the core rod 82 from deflecting when the telescopic rod 8 is extended or retracted.

[0027] For ease of maintenance, a connecting flange is provided at one end of the adjusting rod 4 near the sleeve 81, and the adjusting rod 4 and the sleeve 81 are locked together by multiple bolts. The bolts pass through the flange and can be screwed into the threaded holes at the top of the sleeve 81, making it easy to assemble and disassemble the sleeve 81 and the adjusting rod 4. An end cap 86 is screwed to the lower end of the sleeve 81, and the core rod 82 slides through the interior of the end cap 86, so that after the end cap 86 is unscrewed, the core rod 82 can drive the positioning block 84 to pull out the sleeve 81. The bottom end of the core rod 82 is threadedly connected to the base plate 9, making it easy to disassemble the core rod 82 and the base plate 9. After removing the base plate 9, the end cap 86 can be removed from the bottom end of the core rod 82.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
