Description

Technical Field

[0001] The utility model belongs to the technical field of metal tank safety detection, and in particular relates to a total station bracket fixing tool for metal tank safety detection. Background Art

[0002] Railway tank cars and vertical metal tanks are one of the commonly used equipment in petrochemical and transportation companies, and belong to the category of atmospheric pressure containers and thin-walled structures. External floating roof tank is a common form of vertical metal tank, which is characterized by not only small evaporation loss of stored oil, but also the weight of the tank top is supported by the stored liquid, so that the force is evenly distributed. Therefore, large storage tanks mostly adopt this form. The size of the geometric deformation of the external floating roof tank generally increases with the increase of the time the tank is put into use. After a period of use, due to the rise and fall of the liquid level in the tank, foundation deformation, strong wind and sunshine and other factors, it is inevitable that the tank will undergo a certain deformation. The geometric dimensions of the local convexity and concavity, ovality, maximum inclination, foundation settlement and other geometric dimensions of the tank body are very important indicators. If these indicators are too large, the tank will fail due to stress concentration and cannot be fully utilized or cannot be used at all; in addition, excessive deformation will cause the sealing ring of the floating roof of the tank to be loose, resulting in a high oil and gas concentration, which will not only increase the loss of oil and gas, but also easily become the source of fire and explosion, causing safety hazards to production and personnel. Therefore, it is very necessary to accurately grasp the geometric deformation of the external floating roof tank and conduct a safety assessment.

[0003] At present, the safety inspection of external floating roof tanks usually uses optical reference method and photoelectric method to measure the deformation of the tank. The optical reference method requires the use of optical plumb line, horizontal ruler, mobile magnetic ruler, etc., but this single-point measurement method will produce large measurement errors when the deformation of the tank wall is complex. The photoelectric method generally uses a total station to measure the deformation of the tank, and the total station is fixed on the support of the bracket.

[0004] When inspecting the inside of the tank through a total station, the bottom of the existing bracket will slide when in contact with the steel plate, and the bracket is not convenient to fix, which makes it inconvenient for operators to perform inspection work and is inconvenient to use. Summary of the invention

[0005] In order to solve the defects of the prior art, a total station bracket fixing tool for metal tank safety inspection is provided, which includes three legs. The three legs form a triangular bracket. The legs include a fixed bracket, an adjusting bracket, a fixed sleeve block, a connecting plate, and a supporting block. The adjusting bracket is slidably sleeved in the fixed bracket, a threaded hole is arranged on the side wall of the fixed bracket, and a through hole is arranged on the side wall of the adjusting bracket. Bolts are threadedly connected with the threaded holes and then pass through the through holes. The adjusting bracket is fastened to the connecting plate through the fixed sleeve block, and a support block is arranged on the end of the connecting plate away from the fixed sleeve block.

[0006] Furthermore, a placement slot block is provided in the support block, and a magnetic block is arranged in the placement slot block.

[0007] Furthermore, a magnetic block picking device is arranged on two side walls facing each other where the slot blocks are placed. The magnetic block picking device comprises a picking slot, a picking block and a sliding rod. The picking block is movably sleeved on the sliding rod, and the sliding rod is arranged in the picking slot.

[0008] Furthermore, the fixing sleeve block is fixedly connected to the adjusting bracket. The fixing sleeve block is fixedly connected to the connecting plate.

[0009] Furthermore, the fixing sleeve block is fixedly connected to the adjusting bracket via a locking mechanism, and the fixing sleeve block is fixedly connected to the connecting plate.

[0010] Furthermore, the locking mechanism includes a connecting rod, a fixed block, a fixed rod, a sliding plate, and a spring. The fixed sleeve block is fixedly connected to the connecting rod, the sliding plate is movably sleeved on the connecting rod, the sliding plate is fixedly connected to the fixed block through a spring, the spring is sleeved on the connecting rod, the fixed block is movably connected to the fixed rod, the fixed rod passes through the fixed block and is fixedly connected to the sliding plate, and passes through the sliding plate, the side wall through hole of the fixed sleeve block, and the side wall through hole of the adjustment bracket in sequence.

[0011] Furthermore, the through holes on the side walls of the adjusting bracket are fixing grooves provided at the upper ends of both sides of the adjusting bracket for transporting and fixing the adjusting bracket.

[0012] Furthermore, the through holes on the side walls of the adjusting bracket are fixing grooves provided at the lower ends of both sides of the adjusting bracket for fixing the adjusting bracket in use.

[0013] The beneficial effects of the utility model are as follows: the utility model detects the inside of the tank body through the total station, and the bottom of the stable bracket contacts with the steel plate to avoid sliding, which is convenient for the bracket to be fixed, thereby facilitating the operator to carry out the detection work. The locking mechanism pulls the fixing rod so that the fixing rod drives the sliding plate to slide on the outside of the connecting rod, so that the sliding plate compresses the spring arranged on the side, thereby separating the fixing rod from the fixing groove opened on the top, and then pushes the fixing sleeve block to slide on the outside of the adjusting bracket, and the fixing sleeve block drives the connecting plate to move, and the supporting block arranged at the bottom end of the connecting plate fits with the steel plate, and the magnetic block is clamped in the placement groove block opened inside the supporting block, and the supporting block and the steel plate are fixed by the magnetic force generated by the magnetic block, so that the adjusting bracket can be fixed, on the contrary, the opposite operation is performed, and the fixing sleeve block is fixed to the outside of the adjusting bracket, which is convenient for the adjusting bracket to be inserted into the inside of the soil, and the bracket can be fixed according to the user's use environment, thereby facilitating the operator to carry out the detection work, and the operation is simple and fast, and it is easy to use.
