Description

Technical Field

[0001] The invention relates to the technical field of positioning devices, in particular to a circular ring-shaped base marking positioning device for a spherical tank. Background Art

[0002] As a container for storing high-pressure, flammable and explosive media, the circular foundation of the spherical tank requires extremely high precision. If the deviation is slightly larger, the force on the spherical tank will be uneven after installation, and long-term operation will increase the local stress concentration of the tank body, posing a safety hazard and threatening the safety of life and property. With the expansion of the energy and chemical industries, the large-scale spherical tank has become a trend, and the foundation diameter and complexity have increased, which has led to an exponentially increasing demand for measurement efficiency and accuracy.

[0003] At present, the survey and design of circular foundations of spherical tanks mostly rely on traditional surveying tools, such as theodolites, levels and steel rulers for multi-point measurement and positioning operations. At large-scale project construction sites, the environment is complex, personnel and equipment frequently move back and forth, and traditional methods frequently move and calibrate instruments, which is inefficient and easy to damage instruments due to bumps, resulting in the accumulation of measurement errors and affecting the positioning accuracy of the foundation. There are many measuring points on the circumference of the circular foundation, and the operation is cumbersome, which consumes a lot of manpower and time, delaying the construction period. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a circular foundation marking positioning device for a spherical tank, comprising a triangular bracket, the upper end of which is fixedly connected with a marking body, the marking body comprising a mounting plate, the upper end of which is provided with a ball head, a cylindrical shell is movably provided on the ball head, a plurality of adjusting bolts are threadedly connected to the mounting plate, and the upper ends of the adjusting bolts abut against the lower end of the shell. The movable arrangement of the ball head and the shell, combined with the adjusting bolts, can adjust the level of the shell.

[0005] The side wall of the housing is rotatably provided with a rotating ring, a driving motor is provided inside the housing, and a first gear is provided at the output end of the driving motor, and gear teeth are provided inside the rotating ring, and the gear teeth are meshed with the first gear. That is, when the driving motor is working, the first gear rotates, driving the rotating ring to rotate.

[0006] The side wall of the rotating ring is fixedly connected with a marking rod, and the marking rod includes a sleeve and a telescopic rod, and the telescopic rod extends from the inside of the sleeve, and the end of the telescopic rod is fixedly connected with a laser irradiation device, and the laser irradiation device includes a first shell, and a laser generator and a reflector are arranged inside the first shell. The laser generator faces the reflector, and during the rotation of the reflector, the inclination angle of the laser irradiating the ground is changed. When the device is used, the placement position is determined in advance, and then the laser irradiation device works, the laser irradiates the ground and the staff marks it. At the same time, the laser irradiation device rotates with the rotating ring to form a circular mark on the ground, thereby facilitating subsequent construction.

[0007] Preferably, the first housing is fixedly connected to a deflection mechanism, the deflection mechanism includes a second housing, the second housing is rotatably connected to a second gear, and the end of the reflector is fixedly connected to the second gear, the upper and lower parts of the second gear are meshed with racks, one end of the rack is fixedly connected to an armature, one end of the armature is provided with a spring, and the other end of the spring is against the inner wall of the second housing, and the outer side of the armature is sleeved with a coil. The two coils are energized in a linked manner to generate a magnetic field, which acts on the armature to push the rack, the second gear rotates, and the reflector connected thereto rotates, thereby changing the inclination of the laser irradiating the ground.

[0008] Preferably, the triangular bracket includes a connecting plate, three telescopic legs are rotatably connected to the connecting plate, a support plate is fixedly connected to the upper end of the connecting plate, a stud is fixedly connected to the upper end of the support plate, and the stud is threadedly matched with the mounting plate.

[0009] Preferably, end bearings are provided at the upper and lower ends of the rotating ring, and a bubble level is fixedly connected to the middle of the upper end of the shell, which displays whether the shell is level.

[0010] Preferably, a counterweight structure is fixedly connected to the rotating ring, and the counterweight structure includes a support rod, and a counterweight block is slidably arranged on the support rod. Since the marking rod is fixed to the rotating ring, the center of gravity is not on the rotation axis during the rotation of the rotating ring. During the rotation, the force on the three telescopic legs changes, and the ground is not hardened. During the operation of the device, the shell is bound to tilt. Therefore, a counterweight structure is provided, and the counterweight structure and the marking rod are arranged coaxially. When the marking rod is extended and retracted, the position of the counterweight block is adjusted at the same time to ensure that the center of gravity of the shell is on the rotation axis of the rotating ring.

[0011] Preferably, the support rod is provided with a plurality of grooves, the counterweight block is provided with balls, and the balls and the grooves cooperate with each other. The cooperation between the balls and the grooves is used for limiting the stacking of the weights.

[0012] The beneficial effects of the present invention are as follows: 1.

A triangular bracket is provided to facilitate the support of the device. Adjustment bolts, ball heads and other structures are provided to adjust the level of the shell. In addition, the length of the marking rod can be changed and the laser irradiation angle can be changed. The above structure not only meets the use needs, but also greatly improves the scope of application of the device, that is, it is suitable for the construction needs of circular foundations of different sizes.

[0016] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1 to 10 As shown, the circular foundation marking positioning device for a spherical tank includes a triangular bracket 1, which is a supporting device of the device. The upper end of the triangular bracket 1 is fixedly connected with a marking body 3, and the marking body 3 includes a mounting plate 32. The mounting plate 32 is a circular plate. A ball head 37 is arranged at the upper end of the mounting plate 32. A cylindrical shell 33 is movably arranged on the ball head 37, that is, a ball socket structure is arranged at the middle of the lower end of the shell 33. The matching structure can easily change the inclination angle of the shell 33. A plurality of adjusting bolts 31 are threadedly connected to the mounting plate 32. The upper end of the adjusting bolt 31 abuts against the lower end of the shell 33. At least two adjusting bolts 31 are arranged, and they are arranged at an angle of 90°. That is, the adjusting bolt 31 is rotated to adjust the level of the shell 33.

[0018] The side wall of the housing 33 is rotatably provided with a rotating ring 35, a driving motor is provided inside the housing 33, and a first gear is provided at the output end of the driving motor, gear teeth are provided inside the rotating ring 35, and the gear teeth are meshed with the first gear. When the driving motor is started, the first gear and the gear teeth are driven, thereby driving the rotating ring 35 to rotate. Furthermore, a battery and a satellite positioning module are also provided inside the housing 33.

[0019] The side wall of the rotating ring 35 is fixedly connected with a marking rod 4. When the rotating ring 35 rotates, the marking rod 4 rotates accordingly. The marking rod 4 includes a sleeve 43 and a telescopic rod 42. The telescopic rod 42 extends from the inside of the sleeve 43, that is, the telescopic structure can change its length. In addition, a laser irradiation device 41 is fixedly connected to the end of the telescopic rod 42. The laser irradiation device 41 irradiates laser. The laser irradiation device 41 includes a first shell 411. A laser generator 413 and a reflector 415 are arranged inside the first shell 411. The laser generator 413 is directly opposite to the reflector 415, and the inclination angle of the laser irradiating to the ground is changed during the rotation of the reflector 415. During the operation of the device, the length of the marking rod 4 is pre-adjusted according to the construction requirements. At this time, the laser irradiation generated by the laser generator 413 is vertically irradiated to the ground. The track irradiated on the ground is the construction area, which can be manually marked. If the construction area exceeds the range of vertical laser irradiation, the reflector 415 is used to change the irradiation inclination of the laser, thereby increasing the irradiation range of the laser.

[0020] Further, one end of the sleeve 43 is fixedly connected to the second connector 44, and bolts are inserted on both sides of the second connector 44, and the bolts are threadedly fixedly connected to the rotating ring 35. A battery 412 is also provided inside the first housing 411, and the battery 412 supplies power to the electronic components inside the first housing 411.

[0021] A deflection mechanism 414 is fixedly connected inside the first housing 411, and the deflection mechanism 414 is used to change the angle of the reflector 415. The deflection mechanism 414 includes a second housing 4141, and a second gear 4146 is rotatably connected inside the second housing 4141, and the end of the reflector 415 is fixedly connected to the second gear 4146. Racks 4145 are meshed at the upper and lower parts of the second gear 4146, and one end of the rack 4145 is fixedly connected to an armature 4144, and one end of the armature 4144 is provided with a spring 4142, and the other end of the spring 4142 is against the inner wall of the second housing 4141, and a coil 4143 is sleeved on the outer side of the armature 4144. The two coils 4143 are energized in a linkage manner, and the current size is controlled, that is, the two armatures 4144 are attracted, thereby pushing and pulling the rack 4145, so that the second rack 4146 rotates, thereby changing the tilt angle of the reflector 415. Two sets of coils 4143, springs 4142, armatures 4144 and racks 4146 are provided here. By controlling the current difference between the two coils 4143, the deflection of the gear can be controlled with high precision.

[0022] Furthermore, when the device is in use, the rotation axis of the rotating ring 35 needs to be aligned with the center of the annular foundation, so the device pre-sets the tripod bracket 1, and then adjusts the level of the housing 33. After the adjustment, it is bound to cause a large deviation. Therefore, at this time, the device is aligned with the center of the annular foundation as much as possible, and the position of the rotation axis of the rotating ring 35 is measured by theodolite, level and other equipment. Combined with the preset position of the annular foundation, the deflection mechanism 4141 is linked during the operation of the device, so that the reflector 415 is deflected in real time to ensure that the trajectory of the laser irradiation coincides with the preset position of the annular foundation.

[0023] The triangular bracket 1 includes a connecting plate 12, on which three telescopic legs 11 are rotatably connected. The telescopic legs 11 are unfolded and can provide support. At the same time, the telescopic legs 11 are formed by multiple rods nested with each other. According to the usage scenario, the length and unfolding angle of each telescopic leg 11 can be independently adjusted. The upper end of the connecting plate 12 is fixedly connected to a support plate 13, and the upper end of the support plate 13 is fixedly connected to a stud 14. The stud 14 and the mounting plate 32 are threadedly matched, and the marking body 3 is fixedly connected to the stud 14 through the stud 14.

[0024] The upper and lower ends of the rotating ring 35 are both provided with end bearings 34. The provision of the end bearings 34 improves the smoothness of the rotation of the rotating ring 35. A bubble level 36 is fixedly connected to the middle of the upper end of the shell 33. The bubble level 36 displays whether the shell 33 is horizontal. At the same time, when adjustment is performed by adjusting the adjusting bolt 31, the bubble level 36 provides an indication for the adjustment.

[0025] The rotating ring 35 is fixedly connected with a counterweight structure 2, which plays a balancing role. The counterweight structure 2 and the marking rod 4 are arranged in the same line. The counterweight structure 2 includes a support rod 22, and a counterweight block 23 is slidably arranged on the support rod 22. When the marking rod 4 is extended or retracted, the change in its length will inevitably cause the center of gravity to shift, and most of the ground is not hardened, in order to ensure the stability of the device. Further, a first connecting member 21 is fixedly connected to one end of the support rod 22. The first connecting member 21 and the second connecting member 44 have the same structure and are both provided with bolts. The bolts are fixedly connected to the rotating ring 35. The support rod 22 is provided with a plurality of grooves, and the counterweight 23 is provided with balls, and the balls cooperate with the grooves. The arrangement of the grooves and the balls serves to limit the counterweight 23.

[0026] When in use, use theodolite, level and other equipment to obtain the center of the circular foundation in advance, then place the device at the center and adjust the laser irradiation point. Note that the ground at the irradiation point should be kept level. Then when the device is operating, mark the circular foundation, which greatly improves the efficiency of construction.
