Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping engineering technology, specifically to a support frame for surveying and mapping engineering measuring equipment. Background Technology

[0002] Support frames are mainly divided into three categories: tripods, centering rods, and special brackets. They consist of three legs and a connecting screw at the top, and have an extremely high strength-to-weight ratio. They are lightweight, shock-resistant, and extremely stable, making them very suitable for field operations that require long-distance trekking.

[0003] For example, patent application number 202020804009.9 published on the China Patent Network, entitled "A Conveniently Foldable Measuring Equipment Support Frame," includes a triangular connecting seat. Three sides of the outer wall of the triangular connecting seat are fixedly connected to limiting shells. A fixing plate is provided on one side of the inner cavity of the limiting shell. The fixing plate is fixedly sleeved with the inner wall of the limiting shell. Connecting rods are slidably inserted through the fixing plate. One end of each of the two connecting rods is fixedly connected to a connecting plate, which is located within the inner cavity of the limiting shell. Springs are movably sleeved on the outside of the connecting rods. Connecting blocks are fixedly connected to the other ends of the two connecting rods, and a pressure plate is fixedly connected to the top of the connecting blocks. This utility model utilizes the combination of limiting shells and springs. Through the elastic restoring force of the springs, the connecting plates are pushed away from the fixing plates. The spring force thus secures the level instrument to the triangular connecting seat, avoiding the inconvenience of bolt connections. It is more flexible and practical.

[0004] However, the existing support frame has a relatively simple structure, mainly relying on elastic clamping to connect the equipment to the support frame. The elastic clamping method is easily affected by vibration, which can cause the equipment to fall off and separate.

[0005] Therefore, it is necessary to redesign and modify the support frame for surveying equipment used in surveying engineering. Utility Model Content

[0021] 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.

[0022] like Figures 1 to 4 As shown, the present invention provides a support frame for surveying equipment used in surveying engineering, including a bearing plate 1; A bracket 2 is hinged to the bottom of the support plate 1. A threaded sleeve 3 is movably connected to the bottom of the support plate 1 via a bearing. A screw 4 is threadedly connected to the inside of the threaded sleeve 3. A support rod 5 is movably connected to the bottom end of the screw 4 via a pin. The end of the support rod 5 away from the screw 4 is movably connected to the inner side of the bracket 2 via a pin. An equipment base 6 is slidably inserted into the inside of the support plate 1. Connecting plates 7 are fixedly connected to both sides inside the support plate 1. A transmission rod 8 is inserted into the inner side of the connecting plate 7. A limit plate 9 is fixedly connected to the surface of the transmission rod 8. The side of the limit plate 9 away from the connecting plate 7 extends to the outer side of the equipment base 6. An adjustment structure is provided inside the support plate 1, which can control the opening and closing of the limit plate 9.

[0023] refer to Figure 3 The adjustment structure includes a traction rope 10 fixedly connected to the inside of the limiting plate 9. The traction rope 10 is elastic. The side of the traction rope 10 away from the limiting plate 9 passes through the bearing plate 1 and extends into the interior of the screw sleeve 3. One end of the traction rope 10 located inside the screw sleeve 3 is fixedly connected to the top end of the screw rod 4.

[0024] As a technical optimization of this utility model, the movement of the screw 4 is directly linked to the opening and closing of the limiting plate 9 by using the elastic traction rope 10, which creates a safety logic of unfolding and locking, and the elastic design can buffer vibration.

[0025] refer to Figure 3 A force-bearing plate 11 is fixedly connected to the inner side of the limiting plate 9, and a spring plate 12 is fixedly connected to the inner side of the force-bearing plate 11. The side of the spring plate 12 away from the force-bearing plate 11 is in contact with the inner surface of the bearing plate 1.

[0026] As a technical optimization of this utility model, by adding the spring plate 12, the effect is to provide an automatic reset force, ensuring that the limit plate 9 can automatically and quickly open when the traction rope 10 is slack, which facilitates the picking and placing of equipment.

[0027] refer to Figure 3 Guide wheels 13 are fixedly connected to both sides inside the bearing plate 1, and traction rope 10 is hung on the surface of guide wheel 13 and slidably connected to guide wheel 13.

[0028] As a technical optimization of this utility model, by adding a guide wheel 13, the transmission path of the traction rope 10 is optimized, friction and wear are reduced, making the operation smoother and more durable.

[0029] refer to Figure 4 Both sides of the bearing plate 1 are provided with sleeve plates 14. The inner side of the sleeve plate 14 is fixedly connected to the upright plate 15. The top of the upright plate 15 is fixedly connected to the pressure plate 16. The side of the pressure plate 16 away from the upright plate 15 extends to the top of the bearing plate 1 and penetrates the bearing plate 1. The side of the pressure plate 16 that penetrates the bearing plate 1 contacts the top of the equipment base 6.

[0030] As a technical optimization of this utility model, by adding an upper pressure plate 16, a multi-dimensional clamping device from the side and top is realized, forming a three-dimensional fixation, which greatly enhances the vibration resistance and anti-fall-off capability.

[0031] refer to Figure 4 Both ends of the transmission rod 8 are fixedly connected to a swing rod 17. The side of the swing rod 17 away from the transmission rod 8 extends to the outside of the sleeve plate 14. The end of the swing rod 17 away from the transmission rod 8 is fixedly connected to a push rod 18 located inside the sleeve plate 14. The push rod 18 and the sleeve plate 14 are slidably connected.

[0032] As a technical optimization of this utility model, by linking the pressure plate 16 with the limiting plate 9, the two actions of side clamping and upper pressing can be controlled simultaneously by a single operation, making the structure more compact and the clamping more reliable and efficient.

[0033] The working principle and usage process of this utility model are as follows: When in use, first slide the base of the measuring device into the slot of the bearing plate 1. At this time, the support frame is in the initial state, and the limiting plate 9 opens under the action of the spring plate 12, so that the device can be easily placed. When adjusting the height, the rotating screw sleeve 3 drives the screw 4 to move up and down. When the screw 4 descends and the bracket 2 extends to reduce the height, the traction rope 10 will be tightened simultaneously. The traction rope 10 overcomes the elastic force of the spring plate 12 through the guide wheel 13 and pulls the limiting plates 9 on both sides to move inward, thereby clamping the device base 6 from both sides. At the same time, the transmission rod 8 connected to the limiting plate 9 will drive the swing rod 17 and the push rod 18 to move, so that the pressure plate 16 on the sleeve plate 14 presses down and fixes the device from above. Conversely, when the screw 4 rises and the bracket 2 retracts to increase the height, the traction rope 10 loosens, and the limiting plate 9 moves outward under the action of the elastic force to release the device. The pressure plate 16 also rises accordingly, so that the clamping and release of the device is automatically synchronized with the lifting and lowering of the bracket 2, which effectively improves the stability.

[0034] In summary, the support frame for the surveying equipment used in this surveying project, through the single action of rotating the screw sleeve 3, simultaneously controls the lifting and lowering of the bracket 2 and the clamping of the equipment, thereby fundamentally improving stability through a linkage mechanism and solving the problem of easy loosening with a single elastic clamp.
