Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying and mapping, in particular to a surveying and mapping instrument frame for engineering surveying and mapping. Background Art

[0002] Surveying instruments are the most commonly used surveying tools in engineering surveying. They are instruments and devices designed and manufactured for surveying operations, such as data collection, processing, and output. They are instruments for various orientation, distance, angle, height, mapping, and photogrammetry required for surveying work during the planning, design, construction, and management stages of engineering construction.

[0003] When in use, a surveying instrument is usually equipped with a surveying instrument frame for use. The existing surveying instrument is usually composed of three sets of frames hinged at the bottom of a mounting plate, and a ground cone is fixed at the bottom of the frame. At the same time, each set of frames is individually provided with a structure that can adjust the height. Although the existing device can adjust the height, since each set of frames is individually provided with an adjustment structure, it cannot be adjusted uniformly, which easily leads to inconsistent heights of each set of frames during the adjustment process, resulting in the need for repeated adjustments, thereby reducing the work efficiency of engineering surveying and mapping; in addition, since the existing device is provided with a ground cone at the bottom of the frame, although the ground cone can be inserted into the ground to improve the stability of the device when used on soft land, when used on a cement ground, the ground cone cannot be inserted into the ground, and the area in contact with the ground is small, so the stability is poor, especially in windy weather, the frame is prone to tipping over, causing the surveying instrument to fall, thereby increasing the surveying and mapping cost of engineering surveying and mapping, so the utility model proposes a surveying instrument frame for engineering surveying and mapping to solve the above problems.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-3 The utility model provides a technical solution: a surveying instrument rack for engineering surveying and mapping, comprising a mounting plate 10, three racks 20 arranged at the bottom of the mounting plate 10, and a surveying instrument body 30 for engineering surveying and mapping arranged at the top of the mounting plate 10, a fixing plate 40 is arranged at the bottom of the rack 20, a movable sleeve 50 is arranged at the bottom of the mounting plate 10, a support rod 4001 is arranged on the fixing plate 40, a fixing frame 4002 is arranged on the outer peripheral wall of the support rod 4001, and a fixing rod 4003 is arranged at the bottom of the mounting plate 10. A connecting seat 4004 is provided on the outside of the fixing rod 4003, and a connecting rod 4005 is hinged between the connecting seat 4004 and the three fixing frames 4002. When the height of the rack 20 needs to be adjusted during the engineering surveying process, it is only necessary to move the connecting seat 4004 up and down. In the process of moving the connecting seat 4004, the supporting rod 4001 can be driven to move up and down by the connecting rod 4005, so as to achieve the purpose of synchronously adjusting the height of the three sets of racks 20, avoiding the problem that the traditional device needs to repeatedly adjust the height of the rack 20 for many times.

[0027] The mounting plate 10 is designed in a “triangle” shape, and the three racks 20 are hingedly connected to the mounting plate 10 .

[0028] At the same time, a fixing hole 4006 is opened at the center of the top surface of the fixing plate 40, and the support rod 4001 passes through the fixing hole 4006 and is slidably connected to the fixing hole 4006. A ground cone 4007 is fixed to the bottom end of the support rod 4001. When the device is used on soft soil, the ground cone 4007 can be inserted into the ground to improve the stability of the device. A stop block 4009 is fixed to the top of the support rod 4001 to prevent the support rod 4001 from falling off from the bottom of the frame 20.

[0029] In addition, the fixing rod 4003 is fixed at the center of the bottom surface of the mounting plate 10, and a through hole 4008 is opened on the top of the connecting seat 4004. The fixing rod 4003 passes through the through hole 4008 and is slidably connected to the through hole 4008. The connecting seat 4004 can slide up and down on the outer peripheral wall of the fixing rod 4003. During the upward sliding process, the connecting rod 4005 can be contracted inward to pull the support rod 4001 upward to lower the height of the device. During the downward sliding process, the connecting rod 4005 can be expanded outward to push the support rod 4001 downward to increase the height of the device.

[0030] It should be noted that a threaded hole 41 is provided on one side of the connecting seat 4004, and a plurality of threaded grooves 4101 evenly and equidistantly distributed from top to bottom are provided on one side of the fixing rod 4003. The inner thread of the threaded hole 41 is matched with a screw 4102, and the other end of the screw 4102 extends into the corresponding threaded groove 4101 and is threadedly matched with the thread of the threaded groove 4101. When the device is adjusted to a suitable position, the screw 4102 is rotated, and the fixing rod 4003 and the connecting seat 4004 can be fixed by the screw 4102, and the position of the support rod 4001 can be further fixed.

[0031] See also Figure 2 and Figure 4 A skid plate 5001 is provided at the bottom of the movable sleeve 50, a fixing ring 5002 is provided at the top of the movable sleeve 50, a supporting spring 5003 is provided outside the fixing rod 4003, a screw rod 5004 is provided on one side of the fixing ring 5002, and a baffle 5005 is provided at one end of the fixing rod 4003.

[0032] It can be understood that the movable sleeve 50 is sleeved on the bottom of the outer wall of the fixed rod 4003, and the anti-slip plate 5001 is made of rubber. When the device is used on a cement floor, the movable sleeve 50 can be operated to make the anti-slip plate 5001 fit tightly with the cement floor to increase the friction between the cement floor and the cement floor, thereby improving the stability of the device. The diameter of the baffle 5005 is larger than the inner diameter of the fixing ring 5002, which can prevent the movable sleeve 50 from falling off from the bottom end of the fixed rod 4003.

[0033] It should be emphasized that the support spring 5003 is sleeved on the bottom of the outer surface of the fixed rod 4003, the baffle 5005 is fixed on the bottom end of the fixed rod 4003, and the two ends of the support spring 5003 are respectively abutted between the baffle 5005 and the fixed ring 5002. The support spring 5003 can make the movable sleeve 50 automatically reset after the limit is released by the screw 5004 when the anti-slip plate 5001 is not in use, thereby avoiding the anti-slip plate 5001 from continuously generating friction with the ground when not in use, thereby reducing the service life of the anti-slip plate 5001.

[0034] Finally, a screw hole is provided on the front side of the fixing ring 5002, and the screw rod 5004 passes through the screw hole and is threadedly connected to the screw hole, and the other end of the screw rod 5004 extends into the corresponding thread groove 4101 and is threadedly connected to the thread groove 4101. When the anti-slip plate 5001 is used, the anti-slip plate 5001 is tightly fitted to the ground by pulling down the movable sleeve 50, and then the screw rod 5004 is rotated to engage with the thread groove 4101, thereby limiting the position of the anti-slip plate 5001.

[0035] Specifically, the working principle of the surveying and mapping instrument frame for engineering surveying and mapping is as follows:

[0036] 1. When using the device to carry out engineering surveying on a soft ground, first, according to the height and usage habits of the surveyor, the device is adjusted to a suitable position, which can be achieved by operating the connecting seat 4004. The connecting seat 4004 can be moved upward by contracting the connecting rod 4005 inwardly, thereby pulling the support rod 4001 upward to lower the height of the device. The connecting seat 4004 can be stretched outward by the connecting rod 4005 to push the support rod 4001 downward to increase the height of the device. When the device is adjusted to a suitable position, the screw 4102 is rotated into the corresponding thread groove 4101, and the fixing rod 4003 and the connecting seat 4004 can be fixed by the screw 4102, and the position of the support rod 4001 can be further fixed. Then, the ground cone 4007 is inserted into the ground to fix the device. Finally, the surveying instrument body 30 for engineering surveying is installed on the top of the mounting plate 10 to carry out engineering surveying.

[0037] 2. When using the device to conduct engineering surveying on a cement floor, first, adjust the height of the device according to the height and usage habits of the surveyor according to the above steps. After the height adjustment of the device is completed, place the device at the designated position. Then, pull down the movable sleeve 50 to make the anti-slip plate 5001 fit the cement floor. Next, rotate the screw 5004 to insert the screw 5004 into the corresponding thread groove 4101 to fix the anti-slip plate 5001. Finally, install the surveying instrument body 30 for engineering surveying on the top of the mounting plate 10 to conduct engineering surveying.

[0038] It should be noted that the specific model specifications of the surveying instrument body 30 and the anti-slip pad 5001 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] In addition, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first", "second", "third" and "fourth" may explicitly or implicitly include at least one of such features.
