Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying instruments, in particular to a GPS surveying instrument for construction engineering. Background Art

[0002] GPS measurement for construction projects is a method of using the carrier phase collected by the base station to send to the user's receiver to calculate the coordinates by difference, which greatly improves the user's efficiency in operations such as engineering layout and topographic mapping.

[0003] For example, a GPS measuring instrument for construction engineering with publication number CN219715762U belongs to the technical field of high-precision engineering measurement equipment, which includes a support rod and a receiver arranged at the upper end of the support rod, the receiver is plugged into the upper end of the support rod, a positioning block is provided on the support rod, the side wall on the lower side of the receiver abuts against the side wall of the positioning block, and a fixing part for fixing the support rod is provided on the receiver. The present application has the effect of improving the stability of the support rod and the receiver and ensuring the measurement accuracy.

[0004] However, the above patents do not store the entire device when it is in use, so the entire device will take up a lot of space when placed after use. At the same time, if a worker accidentally touches it during placement, it is very easy to tip over and damage the receiver of the device. At the same time, when the equipment needs to be moved during work, it is generally moved manually. This moving method not only consumes a lot of physical strength of the personnel, but also during the moving process, the personnel cannot always see the entire equipment, which is easy to cause bumps on the equipment, thereby affecting the data measured by the equipment.

[0027] The telescopic component 6 includes a sliding cam 61, a sliding groove 62, a fixed rod 63 and a matching cam 64. The sliding cam 61 is movably arranged on the sliding cavity 5. The sliding cam 61 is slidably connected to the sliding cavity 5. At the same time, the elastic buckle 21 at the bottom of the support rod 2 can be detached from the inside of the sliding cam 61 during the sliding process. The sliding groove 62 is opened through the sliding cam 61. The sliding groove 62 is used for the elastic buckle 21 to slide. During the sliding process, the support rod 2 can be detached. The fixed rod 63 is arranged on the sliding cam 61. The fixed rod 63 is used to cooperate with the matching cam 64 to push the matching cam 64 downward under the rotation of the sliding cam 61. The matching cam 64 is arranged outside the sliding cam 61, and the matching cam 64 and the fixed rod 63 are slidably connected.

[0028] A movably connected sliding disc 7 is provided on the side of the cam 64 away from the sliding cavity 5. The sliding disc 7 is used to connect the telescopic plate 71. The telescopic plates 71 are arranged in an array on the sliding disc 7. The telescopic plates 71 are used to be telescopic and move under the drive of the bracket 4. A connecting rod 72 is provided on the end of the telescopic plate 71 away from the sliding disc 7. A base 73 is provided on the end of the connecting rod 72 away from the telescopic plate 71. The base 73 is a circular ring, which lifts the entire device during the downward movement, so that the universal wheel 43 is separated from the ground to form a locked state of the entire device.

[0029] A movably connected rotating disk 41 is provided at one end of the bracket 4 away from the placement ring 3. The rotating disk 41 is rotatably connected to the bracket 4. When the bracket 4 is opened, it can drive the rotating disk 41 to slide on the Y-shaped slide 81, and the rotating disk 41 is slidably connected to the connecting rod 72. A sliding rod 42 is provided on the rotating disk 41, and the sliding rod 42 is used to slide on the Y-shaped slide 81.

[0030] During use, the bracket 4 is first opened to stabilize the entire device, and then the device can be moved to the designated position under the action of the universal wheel 43. During the moving process, there is no need for staff to move the device, which greatly facilitates the removal of the device. After moving to the designated position, the receiver 1 is extended from the storage state. During the extension process, the elastic buckle 21 at the lower end of the support rod 2 drives the sliding cam 61 to rotate. During the rotation of the sliding cam 61, the fixed rod 63 on the sliding cam 61 will drive the matching cam 64 to rotate. Under the rotation of the matching cam 64, the matching cam 64 can move downward. During the downward movement of the matching cam 64, the sliding disc 7 is moved downward. At the same time, the base 73 lifts up the entire device under the movement of the connecting rod 72 and the telescopic plate 71, and the entire device is locked.

[0031] Example 2

[0032] See also Figures 1 to 5, which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0033] A universal wheel 43 is disposed at one end of the rotating disk 41 away from the telescopic plate 71 . The universal wheel 43 is used to move the entire device, and the universal wheel 43 and the base 73 do not contact each other.

[0034] An L-shaped plate 8 is arranged in an array on one side of the placement ring 3 away from the receiver 1. The L-shaped plate 8 is used to connect the Y-shaped slide 81 and the placement ring 3. A Y-shaped slide 81 is arranged on one end of the L-shaped plate 8 away from the placement ring 3, and the Y-shaped slide 81 is slidably connected to the sliding rod 42.

[0035] A fixing plate 9 is provided on the L-shaped plate 8, and the fixing plate 9 is used to fix the telescopic rod 91, and the telescopic rod 91 is provided on the fixing plate 9. A snap block 93 is provided at one end of the telescopic rod 91 away from the fixing plate 9, and the snap block 93 is used to snap into the notch on the matching cam 64 after the fixing rod 63 moves, so as to prevent the matching cam 64 from rotating in the opposite direction under the action of external force, thereby failing to lock the entire device. A spring 92 is provided on the outside of the telescopic rod 91, and the spring 92 is used to provide elastic force to move the snap block 93 into the notch of the matching cam 64.

[0036] During use, when the fixing rod 63 drives the matching cam 64 to rotate and the fixing rod 63 is displaced, the locking block 93 can directly extend into the slot of the matching cam 64 under the action of the spring 92, and the rotation direction of the matching cam 64 is limited under the action of the locking block 93 so that it will not rotate in the opposite direction. After locking the rotation of the matching cam 64, the base 73 can always remain below the horizontal line of the universal wheel 43, and the entire device can be locked for movement, so that the device will not change its position due to human contact during the measurement process.

[0037] The remaining structures are the same as those of Example 1.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
