Description

Technical Field

[0001] This utility model relates to the field of surveying support technology, and in particular to a surveying instrument support. Background Technology

[0002] The existing surveying support is a tripod used to install surveying instruments during building construction. The surveying instrument is directly installed on the top of the surveying support during use, which makes the surveying support easy and quick to install and use.

[0003] A search revealed that Chinese patent CN202323465925.7 discloses a movable and stable surveying support for power construction. The tripod support has three legs of adjustable length, each containing a threaded pipe. The relative rotation of the threaded pipes adjusts the length of the leg. The ends of the three legs are pointed. On flat ground, when movement is needed, a slight turn of the handwheel will turn the caster downwards, allowing for easy movement. When support is required, a slight reverse turn of the handwheel will move the support upwards, and then the legs will provide support.

[0004] The above-mentioned technical solution has the following drawbacks: although such a surveying instrument bracket can be moved by a handwheel and can be extended for support during use, in actual surveying work, it is still relatively difficult to move the tripod to the surveying point using only a single handwheel. In order to improve the efficiency of surveying work, a surveying instrument bracket is proposed, which is equipped with retractable pulleys at the bottom. These pulleys can be extended during transportation, making it easy to move the surveying instrument bracket within the surveying area. When it is moved to the surveying point, it can be retracted. The surveying instrument bracket can then be stably placed on the ground with the surveying instrument set up to carry out the surveying work.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides a surveying instrument bracket that solves the problems mentioned in the background. The bottom is equipped with retractable pulleys that can be pulled out during transportation, making it easy to move the surveying instrument bracket within the surveying area. When it is moved to the surveying point, it can be stored away. The surveying instrument bracket can be stably placed on the ground and the surveying instrument can be set up to carry out surveying work.

[0008] The present invention provides the following solution to the above-mentioned technical problems: A surveying instrument bracket includes a movable bracket housing, a movable base plate, and a surveying instrument mounting base. The movable bracket housing is rotatably connected to two ball screws. A brake motor is fixedly mounted on the movable bracket housing, and the drive end of the brake motor is fixedly connected to the ball screws. Screw nuts are threaded onto the ball screws on both sides. Universal wheels are fixedly mounted on the movable base plate. Synchronous pulleys are fixedly mounted on both sides of the ball screws, and synchronous belts are driven by the synchronous pulleys on both sides. A handle is fixedly mounted on the movable bracket housing. A hydraulic cylinder is rotatably connected to the movable bracket housing and is rotatably connected to the surveying instrument mounting base. Two adjusting cylinders are rotatably connected to the surveying instrument mounting base. Adjusting sliders are slidably connected to the inner walls of the two adjusting cylinders. Positioning screws are threaded onto the adjusting sliders, and bracket support rods are fixedly connected to the adjusting sliders.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the movable housing of the support is provided with a sliding groove that is compatible with the lead screw nut, and the inner wall of the sliding groove is slidably connected to the lead screw nut, so that the lead screw nut can be stably raised and lowered within the movable housing of the support.

[0011] Furthermore, the brake motor is fixedly connected to a motor bracket, and the motor bracket is fixedly connected to the support moving housing, so that the brake motor can be stably installed in the support moving housing.

[0012] Furthermore, the bottom of the adjusting cylinder has a sliding hole corresponding to the support rod, and the inner wall of the sliding hole is slidably connected to the support rod, so that the support rod can be extended and retracted within the adjusting cylinder.

[0013] Furthermore, the outer wall of the adjusting cylinder has a slotted hole corresponding to the positioning screw, allowing the positioning screw to slide within the slotted hole, thereby positioning the adjusted bracket support rod.

[0014] Furthermore, the bottom of the movable support box is provided with a storage groove corresponding to the movable base plate, so that the movable base plate can be stored inside the movable support box.

[0015] Furthermore, ground nails are evenly fixedly installed at the bottom of the movable support box near the edge, so that the movable support box can be stably placed on the ground.

[0016] Furthermore, the support rod is fixedly connected to a ground-inserting drill bit, allowing the support rod to be stably inserted into the ground.

[0017] This utility model provides a surveying instrument bracket, which has the following advantages:

[0018] 1. The synchronous pulleys on the outer walls of the ball screws on both sides are connected by a synchronous belt. When the brake motor is started, the ball screw on one side can be rotated synchronously, which can drive the ball screw on the other side to rotate synchronously. The ball screws on both sides can drive the movable base plate to slide on the inner wall of the bracket movable box through the screw nut. When the mobile equipment needs to be moved, the universal wheels at the bottom of the movable base plate can be taken out from the storage slot of the bracket movable box. The equipment on the top of the universal wheels can be moved by the handle.

[0019] 2. When the equipment needs to be moved after it has been moved to the surveying position, the base plate and the casters at the bottom can be retracted into the interior of the support moving box. The ground nails can be inserted into the ground, so that the support moving box can be stably placed on the ground. Rotate the hydraulic cylinder and adjust the length of the hydraulic cylinder according to the size of the worker. Rotate to open the two side adjustment cylinders. After loosening the positioning screw, the adjustment slider can slide on the inner wall of the adjustment cylinder, so that the support rod of the support can extend from the adjustment cylinder for length adjustment. After adjustment, tighten the positioning screw, and the ground drill bit can be inserted into the ground for positioning. The surveying equipment can then be stably and reliably installed at the surveying instrument mounting base for surveying work.

[0020] 3. This type of surveying instrument bracket is equipped with retractable casters at the bottom, which can be pulled out during transportation, making it easy to move the surveying instrument bracket within the surveying area. When it is moved to the surveying point, it can be stored away. The surveying instrument bracket can be placed stably on the ground and the surveying instrument can be set up to carry out surveying work. It is suitable for outdoor surveying operations in large areas, which can effectively reduce manpower and improve work efficiency.
