Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping positioning, and specifically relates to an outdoor surveying and mapping positioning device. Background Art

[0002] Surveying instruments are needed in outdoor surveying. To ensure the accuracy of the measured values, the surveying instruments need to be placed in a stable environment. Since it is difficult to place the surveying instruments horizontally outdoors, a positioning device is required for assistance.

[0003] A Chinese patent with publication number CN216480002U discloses a surveying instrument positioning device for engineering surveying. The device is provided with a surveying positioning device. After the device is unfolded and placed on the ground, the four threaded rods can be rotated according to the horizontal condition displayed by the level meter. The threaded rods can be raised and lowered by threaded connection with the threaded barrel. At this time, the spherical slider provided at the top of the threaded rod is connected with the hemispherical groove to adjust the height of the four corners of the surveying platform, so that the surveying platform is adjusted to a horizontal state, and then the surveying instrument can be placed for use. At the same time, through the provided connection device and adjustment device, the adjustment device can be stored and folded to the bottom side of the surveying positioning device, thereby realizing folding and storage, which is convenient for carrying outdoors.

[0004] However, in actual use, since the rotating plate in the connecting device limits the friction force generated by the extrusion of the ear plate by the support screw and the fixed nut, and the weight of the surveying and mapping instrument is usually large, when the surveying and mapping instrument is placed on the surveying and mapping platform, the gravity is indirectly transmitted to the ear plate, and the gravity may overcome the friction force and drive the ear plate to rotate around the support screw, that is, the ear plate drives the surveying and mapping platform to rotate, which leads to poor stability of the above scheme. Utility Model Content

[0005] The utility model aims to provide an outdoor surveying and positioning device to solve the problem of poor stability of the prior art mentioned above.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions: an outdoor surveying and positioning device, comprising

[0007] A surveying platform with a cross brace installed at the bottom;

[0008] A level adjustment mechanism is installed on the cross support plate and is used to adjust the level of the surveying platform;

[0009] The storage mechanism includes a sliding sleeve, an adjustment plate, a locking bolt and a connecting plate. The sliding sleeve is installed at the bottom of the cross support plate. The adjustment plate and the sliding sleeve are slidably inserted. The locking bolt is threadedly inserted on the side wall of the sliding sleeve, and the end thereof abuts against the adjustment plate. The L-shaped connecting plate is installed at the bottom of one end of the adjustment plate.

[0010] The supporting mechanism includes a connecting seat, a connecting bolt, a locking nut, a main shaft, a stabilizing rod and multiple groups of supporting units. The connecting seat is installed at the bottom of the connecting plate. The connecting bolt passes through the connecting seat and cooperates with the locking nut thread. The locking nut abuts against the outer wall of the connecting seat. The top of the main shaft is located on the inner side of the connecting seat and is connected to the connecting bolt. The main shaft is provided with a stabilizing groove. One end of the stabilizing rod is slidably hinged to the stabilizing groove, and the other end of the stabilizing rod is hinged to the outer wall of the sliding sleeve. The multiple groups of supporting units are arranged at intervals along the circumference of the main shaft.

[0011] The principle and effect of this technical solution:

[0012] 1. The surveying platform can be adjusted through the horizontal adjustment mechanism, so that the surveying instrument placed on the surveying platform can be in a horizontal state to survey the land or engineering projects. The storage mechanism controls and stores the supporting mechanism, so that the device can be folded and unfolded, so that the device can reduce space occupation during transportation and facilitate transportation. It can be unfolded when in use to provide stable support.

[0013] 2. By sliding the adjustment plate, the position of the connecting plate relative to the sliding sleeve can be changed, and by rotating the locking bolt, the locking bolt can be abutted against the adjustment plate, and then the adjustment plate is limited by friction. The position change of the connecting plate will simultaneously drive the support mechanism installed under the connecting plate to change its position. Since the top of the main shaft is indirectly hinged to the connecting plate, and one end of the stabilizing rod is slidably hinged in the stabilizing groove of the main shaft, the stabilizing rod, the main shaft and the connecting plate constitute a crank slider mechanism. By controlling the position of the connecting plate, the main shaft can be driven to rotate, so that the stabilizing rod rotates in the stabilizing groove of the main shaft. That is, when the device plays a supporting role, since the adjustment plate can only move horizontally and the gravity of the surveying and mapping instrument is vertically downward, the adjustment plate can be stably fixed by friction. At this time, the position of the connecting plate cannot be changed due to the fixing of the adjustment plate, thereby causing the end of the main shaft to be unable to change its position, that is, the stabilizing rod cannot move along the stabilizing groove, so that the stabilizing rod can play a supporting and limiting role on the main shaft through the restriction of the stabilizing groove, so that the top of the main shaft cannot rotate around the connecting plate.

[0014] 3. The top of the main shaft is connected to the connecting bolt, so that the main shaft can rotate with the rotation of the connecting bolt, that is, the main shaft can rotate relative to the connecting seat, and the locking nut can be abutted against the connecting seat by rotating the locking nut, so that the rotation of the main shaft is further limited by the abutment force. When the main shaft plays a supporting role, it is not only limited by the stabilizing rod and the stabilizing groove, but also by the friction between the locking nut and the connecting seat, and the stability is stronger.

[0015] 4. The position of the connecting plate can be changed by changing the position of the adjusting plate, so that the stabilizing rod drives the main shaft to change. That is, the user can control the expansion of the main shaft by controlling the position of the adjusting plate, which is simple and convenient to operate.

[0016] The utility model is further configured as follows: the supporting unit comprises an abutment rod and a control assembly, the top of the abutment rod is rotatably connected to the outer wall of the main shaft, the control assembly is arranged on the main shaft and is used to control the position of the abutment rod.

[0017] The principle and effect of this technical solution: by controlling the control component to limit the rotating abutment rod, the abutment rod can be unfolded when supporting, so as to contact the ground and play a stable supporting role. When storing, it rotates and contracts, so as to facilitate transportation.

[0018] The utility model is further configured as follows: the support unit also includes an insert rod, and the insert rod is threadedly sleeved on the bottom of the abutment rod.

[0019] The principle and effect of this technical solution: by inserting the insertion rod into a softer soil layer, the device can be fixed more stably, and by rotating the insertion rod, the matching length of the insertion rod and the abutment rod can be changed, that is, the overall length of the abutment rod and the insertion rod can be adjusted. When the ground is uneven, the support mechanism can be stably placed on the ground through this adjustment, so that the surveying and mapping platform can provide stable support for the surveying and mapping instruments.

[0020] The utility model is further configured as follows: a control component includes a driving ring, a fixed ring, a first control rod, a second control rod and a rotating shaft; the fixed ring is sleeved on the bottom of the main shaft; the driving ring is slidably sleeved on the main shaft and is connected to the stabilizing rod; a control groove is provided on the rod body of the abutting rod; one end of the first control rod is hinged to the outer wall of the driving ring; the other end of the first control rod is rotatably connected to the rotating shaft; one end of the second control rod is rotatably connected to the rotating shaft; the other end of the second control rod is hinged to the outer wall of the fixed ring; and the rotating shaft is slidably installed in the control groove.

[0021] The principle and effect of the technical solution are as follows: since the driving ring, the fixing ring, the first control rod, the second control rod, the rotating shaft and the abutting rod are respectively hingedly connected to each other, a crank slider mechanism is formed, which is connected to the driving ring through the stabilizing rod, so that the stabilizing rod can drive the driving ring to slide on the main shaft, and then the driving ring drives the first control rod to change its position, and the first control rod drives the rotating shaft to slide in the control groove, thereby driving the abutting rod and the second control rod to rotate, and the stabilizing rod is indirectly limited by limiting the position of the adjusting plate, so that the driving ring cannot move, that is, the crank slider mechanism related to the driving ring cannot change its position, so that the control component can control the abutting rod to play a stable support, and can also store and fold the abutting rod through the control component, so as to facilitate storage and storage during transportation, and the driving ring is connected to the stabilizing rod, so that the user can indirectly control the abutting rod to unfold and store by controlling the position of the adjusting plate, so that the device forms a driving whole, and the operation is simpler.

[0022] The utility model is further configured as follows: the number of the supporting units is three groups.

[0023] The principle and effect of this technical solution: three groups of support units can play a supporting role, and because the number of support units is the least, when the support units and the support mechanism are controlled, the component resistance is minimal, which is easy to adjust and has high stability.

[0024] The utility model is further configured as follows: the storage mechanism also includes a limit assembly, the limit assembly includes a limit cylinder, a limit rod, a baffle, a limit spring and a pull plate, the limit cylinder is fixed on the outer wall of the sliding sleeve and is located on the side of the sliding sleeve away from the locking bolt, a limit hole is provided on the adjusting plate, the limit rod is slidably inserted into the limit cylinder, and the end of the limit rod extends into the limit hole, the baffle is slidably fitted in the limit cylinder and is mounted on the limit rod, the pull plate is connected to one end of the limit rod away from the adjusting plate, the limit spring is installed in the limit cylinder and is located on the side of the baffle away from the adjusting plate.

[0025] The principle and effect of the technical solution: through the setting of the limit assembly, when the adjustment plate controls the support mechanism to extend or fold and store, the limit rod can be inserted into the limit hole of the adjustment plate to limit the adjustment plate laterally, so that the adjustment plate will not slide relative to the sliding sleeve, that is, when the abutment between the locking bolt and the adjustment plate is loose, the adjustment plate cannot slide relative to the sliding sleeve, so that the support mechanism can provide stable support, thereby improving the stability of the device when in use.

[0026] The utility model is further configured as follows: two stabilizing rods are provided and are symmetrically distributed about the sliding sleeve.

[0027] The principle and effect of this technical solution: the setting of two stabilizing rods can make the limiting force or driving force of the stabilizing rods on the main shaft more uniform, so that the force on the main shaft is more balanced, so that the stabilizing rods can drive and adjust the main shaft, making the adjustment of the main shaft by the stabilizing rods more stable.
