Description

Technical Field

[0001] This utility model relates to the field of engineering construction surveying equipment technology, specifically a surveying device for engineering construction. Background Technology

[0002] During engineering construction, many surveying tasks require the use of surveying equipment. Surveying equipment typically consists of a height-adjustable tripod and a surveying instrument body mounted on it. The tripod includes three hollow outer rods located under the surveying instrument body, and an inner rod located inside the outer rods that can slide up and down along the outer rods and is fixedly connected to the outer rods. The end of the inner rod furthest from the outer rods is a pointed end. For example, the surveying auxiliary surveying support with application number CN202321782583.9 has such a structure. The pointed end allows the surveying equipment to be placed stably on the ground.

[0003] However, during the measurement process, it was found that the operation steps were very troublesome when changing the measurement position. First, because the surveying instrument itself is heavy, it is necessary to disassemble the surveying instrument first, and after the bracket is moved to the measurement position and placed, the surveying instrument is then installed on the bracket and leveled before the measurement can be carried out. This process is time-consuming and laborious, and the work efficiency is low. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a surveying device for engineering construction.

[0005] The technical solution of this utility model is as follows:

[0006] A surveying device for engineering construction includes a support frame and a measuring instrument body mounted on it. The support frame includes multiple adjustable legs, and the height of the support frame can be adjusted by adjusting the length of the legs during use.

[0007] As the core technical concept of this utility model, the lower end of the support leg is also connected to a horizontal bar, the lower side of the horizontal bar is provided with a movable wheel, and the middle part of the horizontal bar is provided with a fixing mechanism that can fix the support frame. Specifically, the fixing mechanism includes a fixing rod that slides vertically through the horizontal bar, and the horizontal bar is also provided with a locking mechanism that can fix its height.

[0008] When this surveying device needs to be moved, adjust the height of the fixing rod to be away from the ground, and push the support frame, which will move under the action of the moving wheels; when this surveying device needs to be fixed, adjust the height of the fixing rod to be close to the ground to fix the support frame.

[0009] As one implementation method, an elastic element is provided between the fixed insertion rod and the horizontal rod, and the fixed insertion rod is subjected to the elastic force of the elastic element upward. In use, the fixed insertion rod is restricted to move upward by a locking mechanism, thereby achieving a fixed height of the fixed insertion rod. The elastic element is preferably a spring.

[0010] As a further implementation, the locking mechanism is locked by a laterally elastic insertion and fixation with the fixed plug rod.

[0011] Specifically, the fixed rod has several slots arranged vertically in a row that can cooperate with the locking mechanism. The upper sidewall of the slot is an inclined surface facing downwards and outwards, while the lower sidewall is a horizontal surface. In use, the fixed rod is pressed down by external force. Due to the structure of the slot, the locking mechanism can automatically release the lateral elastic engagement with the fixed rod as the fixed rod moves downwards, thus facilitating the adjustment of the fixed rod.

[0012] Furthermore, the locking mechanism includes a locking rod that is laterally and elastically inserted into the fixed rod, and the side of the locking rod that fits against the inner side of the slot is a concave arc surface. The design of the concave arc surface makes the locking rod more stable when inserted into the fixed rod and less prone to loosening. Compared with the traditional planar contact method, the design of the concave arc surface can reduce the friction and wear between the locking rod and the slot.

[0013] Furthermore, the horizontal bar has a vertical hole corresponding to the fixed insertion rod, and a sliding groove communicating with the vertical hole is opened laterally at the outer end. The locking rod is slidably disposed in the sliding groove, and the outer end of the horizontal bar is also provided with an end plate. A spring is also provided between the locking rod and the end plate. During installation, the locking rod and the spring are installed on the horizontal bar in sequence through the sliding groove. The inner side of the locking rod and the fixed insertion rod are engaged in the vertical hole, and the outer side of the spring is fixed by the end plate. The end plate is detachably connected to the outer end of the horizontal bar.

[0014] To facilitate upward adjustment of the fixed rod, a transverse sliding hole is provided on one side of the horizontal bar corresponding to the sliding groove. A pull rod connected to the locking rod is also provided in the transverse sliding hole. When in use, pull the pull rod outward, the locking rod slides outward along the sliding groove and compresses the spring. At this time, the locking rod releases its engagement with the fixed rod, and the fixed rod moves upward under the action of the elastic element between it and the horizontal bar. The whole process only requires pulling the pull rod, which is very convenient.

[0015] Furthermore, the lever has an inward-facing U-shaped structure, with its two sides connected to the two sides of the locking rod. When in use, the operator can insert their toes into the U-shaped opening of the lever and pull it outward with a little force, making the operation more convenient.

[0016] To prevent the fixed insertion rod from detaching from the horizontal bar, a long strip-shaped sliding hole is vertically opened on the fixed insertion rod, passing through both sides, and a limiting shaft is horizontally inserted through the sliding hole on the horizontal bar.

[0017] As described above, the surveying device for engineering construction has an adjustable angle between the horizontal bar and the support legs to improve its flexibility of use.

[0018] The beneficial effect of this utility model of a surveying device for engineering construction is that, through the setting of a horizontal bar and its moving wheels and fixing mechanism, this surveying device can not only be moved without disassembling the main body of the measuring instrument, but also be fixed at any time under the action of the fixing mechanism, which not only facilitates use, but also improves work efficiency.

[0027] Combination Figure 1 This embodiment provides a surveying device for engineering construction, including a support frame and a measuring instrument body installed on it. The support frame includes multiple adjustable legs, each leg including an upper sleeve rod 1 and a lower sleeve rod 2 slidably disposed inside its lower end. In use, the height of the support frame can be adjusted by adjusting the length of the legs. Typically, there are three legs.

[0028] As the core technical concept of this utility model, the lower end of the lower sleeve rod 2 is also provided with a horizontal rod 3 along its outer side, the lower side of the horizontal rod 3 is provided with a movable wheel 4, and the middle part of the horizontal rod 3 is provided with a fixing mechanism 5 that can fix the support frame. Specifically, the fixing mechanism 5 includes a fixing rod 51 that slides vertically through the horizontal rod 3, and the fixing rod 51 is located outside the movable wheel 4. The lower end of the fixing rod 51 is a pointed structure, and the horizontal rod 3 is also provided with a locking mechanism that can fix its height.

[0029] Combination Figure 2 and Figure 4 An elastic element is provided between the fixed insertion rod 51 and the horizontal rod 3, and the fixed insertion rod 51 is subjected to the elastic force of the elastic element and moves upward. In use, the locking mechanism restricts the fixed insertion rod 51 from moving upward, thereby achieving the height fixation of the fixed insertion rod 51. In this embodiment, the elastic element is the first spring 52.

[0030] The locking mechanism is locked by a horizontal elastic insertion with the fixed rod 51. The fixed rod 51 is a T-shaped structure, including an upper pedal and a lower cylindrical rod. The cylindrical rod is vertically slidably mounted on the horizontal rod 3. The first spring 52 is sleeved on the cylindrical rod between the pedal and the horizontal rod 3. The cylindrical rod has a number of slots 511 arranged vertically to cooperate with the locking mechanism. The upper sidewall of the slot 511 is an inclined surface facing downwards and outwards, and the lower sidewall is a horizontal surface.

[0031] When in use, by pressing down the pedal with external force, the locking mechanism can automatically release the lateral elastic connection with the fixed rod 51 during the downward movement of the cylindrical rod through the structural setting of the slot 511, thereby facilitating the adjustment of the fixed rod 51.

[0032] To prevent the fixed insertion rod 51 from detaching upward from the horizontal rod 3, a long strip-shaped sliding hole 512 is vertically opened on the cylindrical rod and passes through both sides of it. A limiting shaft 53 is horizontally inserted on the horizontal rod 3 and passes through the sliding hole 512.

[0033] Combination Figure 5 The locking mechanism includes a locking rod 54 that is laterally and elastically inserted into the cylindrical rod. The side of the locking rod 54 that is in contact with the inner side of the slot 511 is a concave arc surface. The concave arc surface design makes the locking rod 54 more stable when inserted into the fixing rod 51 and less prone to loosening. Compared with the traditional planar contact method, the concave arc surface design can reduce the friction and wear between the locking rod 54 and the slot 511.

[0034] The horizontal rod 3 has a vertical hole corresponding to the cylindrical rod, and a groove 32 communicating with the vertical hole is opened laterally at the outer end. The locking rod 54 is slidably disposed in the groove 32, and the outer end of the horizontal rod 3 is also provided with an end plate 31. A second spring 55 is also provided between the locking rod 54 and the end plate 31.

[0035] The locking rod 54 has a T-shaped structure with an outer diameter larger than the inner diameter. During installation, the inner side of the second spring 55 is connected to the outer side of the locking rod 54. Then, the locking rod 54 is installed in the horizontal rod 3 through the sliding groove 32. Finally, the end plate 31 is installed on the outer end of the horizontal rod 3. The inner side of the locking rod 54 is inserted into the cylindrical rod in the vertical hole. The outer side of the second spring 55 is fixed by the end plate 31, and the end plate 31 is detachably connected to the outer end of the horizontal rod 3 to facilitate the installation and removal of the locking rod 54 and the second spring 55.

[0036] To facilitate upward adjustment of the fixed rod 51, a transverse sliding hole 512 is provided on one side of the horizontal rod 3 corresponding to the sliding groove 32. A pull rod 6 connected to the locking rod 54 is also provided in the transverse sliding hole 512. In use, the pull rod 6 is pulled outward, and the locking rod 54 slides outward along the sliding groove 32 and compresses the spring. At this time, the locking rod 54 is released from its insertion into the cylindrical rod, and the fixed rod 51 moves upward under the action of the elastic element between it and the horizontal rod 3. The whole process only requires pulling the pull rod 6, which is very convenient.

[0037] Combination Figure 4 The lever 6 has an inward-facing U-shaped structure, with its two sides connected to the two sides of the locking lever 54. When in use, the operator can insert their toes into the U-shaped opening of the lever 6 and pull the lever 6 outward with a little force, making the operation more convenient.

[0038] To improve the flexibility of this surveying device, the angle between the horizontal bar 3 and the support leg is adjustable.

[0039] Specifically, an adjustment knob is provided between one end of the inner side of the horizontal bar 3 and the lower end of the outrigger, and the adjustment knob is configured to adjust the angle between the horizontal bar 3 and the outrigger.

[0040] When this surveying device needs to be moved, pull the lever 6 outward, compress the second spring 55, and slide the locking lever 54 away from the fixed insertion rod 51 outward. At this time, the fixed insertion rod 51 slides upward under the elastic force of the first spring 52 until the limiting shaft 53 contacts the lower side of the sliding hole 512, and the fixed insertion rod 51 stops sliding upward. At this time, the fixed insertion rod 51 is in a state away from the ground (reference). Figure 3 At this time, by pushing the support frame, the support frame moves under the action of the moving wheel 4.

[0041] When this surveying device needs to be fixed, press down on the pedal with your foot / hand. The first spring 52 is compressed, and the fixing rod 51 slides downward. At this time, since the upper sidewall of the slot 511 is an inclined surface facing downward and outward, and the lower sidewall is a horizontal surface, as the fixing rod 51 slides downward, it pushes the locking rod 54 to slide outward and compresses the second spring 55. When the fixing rod 51 contacts the ground, stop pressing down on the pedal. At this time, under the elastic force of the second spring 55, the locking rod 54 slides inward and engages with the slot 511, thereby adjusting the height of the fixing rod 51 to be pressed against the ground, thus achieving the fixation of the support frame (see reference). Figure 2 ).
