Description

Technical Field

[0001] The utility model relates to the technical field of steel structure measurement, in particular to a measurement device for super high-rise steel structures. Background Art

[0002] In super high-rise steel structure buildings, the steel structure is the core load-bearing system, and its installation accuracy and stability are directly related to the safety and service life of the entire building. Super high-rise steel structures are usually composed of steel columns, steel beams, and steel truss members. These members need to be measured in multiple dimensions of angle, length, and height during the installation process to ensure the accuracy and stability of the overall structure. During the installation of steel columns and steel beams, angle measurement is a crucial link. Traditionally, this measurement work mostly relies on manual use of two hinged angle measuring rods.

[0003] However, this method has significant limitations:

[0004] When the angle measuring rod contacts the steel structure, due to the uneven surface of the steel structure or improper operation, the angle measuring rod is prone to rotate, resulting in deviation of the measured angle, thus affecting the overall measurement accuracy. For places with a certain height on the steel structure, the measurement personnel need to work at heights, which not only increases the difficulty of the measurement work but also brings higher safety risks.

[0005] To solve the above problems, a measurement device for super high-rise steel structures is proposed in this application. Content of the Utility Model

[0006] Based on the technical problems existing in the background art, the utility model proposes a measurement device for super high-rise steel structures.

[0007] A measurement device for super high-rise steel structures proposed by the utility model includes a protractor and two angle measuring rods;

[0008] One ends of the two angle measuring rods are rotatably connected to the middle of the protractor;

[0009] A fixing rod is connected to the bottom of the protractor. An adjusting member for adjusting the angle between the two angle measuring rods is slidably sleeved on the fixing rod, and an elastic pressing member for pressing against the fixing rod is installed on the adjusting member;

[0010] A rod-type driving member for adjusting its length is installed at one end of the fixing rod away from the protractor;

[0011] A telescopic member for pushing the adjusting member to slide on the fixing rod is installed on the adjusting member.

[0012] Preferably, the adjusting member includes an adjusting cylinder which is slidably sleeved on the fixed rod. Connecting rods are hinged to both sides of the adjusting cylinder. Blocks are hinged to the ends of the two connecting rods away from the adjusting cylinder, and the two blocks are respectively slidably sleeved on the two angle measuring rods.

[0013] Preferably, the elastic pressing member includes a pressing rod. A jack is formed in the side surface of the adjusting cylinder. The pressing rod slidably passes through the jack and presses against the fixed rod. An end block is installed at the end of the pressing rod away from the fixed rod. A spring is sleeved on the pressing rod between the adjusting cylinder and the end block, and both ends of the spring are respectively connected to the adjusting cylinder and the end block.

[0014] Preferably, the rod-type driving member includes a fixed cylinder and an electric push rod. The fixed cylinder is arranged at the end of the fixed rod away from the angle measuring ruler. An insertion cavity is formed in the fixed cylinder. The electric push rod is installed in the insertion cavity. The end of the fixed rod away from the angle measuring ruler is inserted into the insertion cavity and connected to the electric push rod, and the fixed rod is driven by the electric push rod to move in the insertion cavity.

[0015] Preferably, the telescopic member includes a fixed shaft which is rotatably connected to one side of the adjusting cylinder. A telescopic rod is connected to the fixed shaft. A sleeve is slidably sleeved on the telescopic rod, and a bolt which presses against the telescopic rod is threadedly connected to the outer circumference of the sleeve.

[0016] The above technical solution of the present utility model has the following beneficial technical effects:

[0017] When measuring the angles of some steel structures at relatively high positions by means of the provided adjusting member, elastic pressing member, telescopic member and rod-type driving member, the overall extension length of the fixed rod can be adjusted by the rod-type driving member. Then, the two angle measuring rods on the angle measuring ruler can be placed at the positions of the steel structure where angle measurement is required. The adjusting member is pushed by the telescopic member to slide on the fixed rod, so as to adjust the angle between the two angle measuring rods. The angles of the steel structure are measured by the two angle measuring rods. Since an elastic pressing member which presses against the fixed rod is installed on the adjusting member, when the angle measuring rods contact the steel structure, under the pressing action of the elastic pressing member, the rotation of the angle measuring rods can be prevented, so as to maintain the stability of the angle measuring rods. This structure can realize the measurement of steel structures at relatively high positions, and can effectively prevent the rotation of the angle measuring rods during the measurement of steel structures, so as to maintain the measurement accuracy.

Specific embodiments

[0022] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0023] As Figures 1-3 shown, a super high-rise steel structure measuring device proposed by the present utility model includes a protractor 1 and two angle measuring rods 2;

[0024] In this embodiment, one ends of the two angle measuring rods 2 are both rotatably connected to the middle of the protractor 1.

[0025] In this embodiment, a fixed rod 3 is connected to the bottom of the protractor 1, and an adjusting member 4 for adjusting the angle between the two angle measuring rods 2 is slidably sleeved on the fixed rod 3. The adjusting member 4 includes an adjusting cylinder 41 which is slidably sleeved on the fixed rod 3. Connecting rods 42 are hinged to both sides of the adjusting cylinder 41. One ends of the two connecting rods 42 far from the adjusting cylinder 41 are both hinged with sleeve blocks 43, and the two sleeve blocks 43 are respectively slidably sleeved on the two angle measuring rods 2.

[0026] In this embodiment, an elastic pressing member 5 which presses against the fixed rod 3 is installed on the adjusting member 4. The elastic pressing member 5 includes a pressing rod 51. A jack is formed on the side surface of the adjusting cylinder 41. The pressing rod 51 slidably passes through the jack and presses against the fixed rod 3. An end block 52 is installed at one end of the pressing rod 51 far from the fixed rod 3. A spring 53 located between the adjusting cylinder 41 and the end block 52 is sleeved on the pressing rod 51, and both ends of the spring 53 are respectively connected to the adjusting cylinder 41 and the end block 52.

[0027] In this embodiment, a rod-shaped driving member 7 for adjusting its length is installed at one end of the fixed rod 3 away from the protractor 1. The rod-shaped driving member 7 includes a fixed cylinder 71 and an electric push rod 72. The fixed cylinder 71 is arranged at one end of the fixed rod 3 away from the protractor 1. An insertion cavity is formed in the fixed cylinder 71. The electric push rod 72 is installed in the insertion cavity. One end of the fixed rod 3 away from the protractor 1 is inserted into the insertion cavity and connected to the electric push rod 72, and the fixed rod 3 is driven by the electric push rod 72 to move in the insertion cavity.

[0028] In this embodiment, a telescopic member 6 for pushing the adjusting member 4 to slide on the fixed rod 3 is installed on the adjusting member 4. The telescopic member 6 includes a fixed shaft 61. The fixed shaft 61 is rotatably connected to one side of the adjusting cylinder 41. A telescopic rod 62 is connected to the fixed shaft 61. A sleeve 63 is slidably sleeved on the telescopic rod 62. A bolt 64 that presses against the telescopic rod 62 is threadedly connected to the outer periphery of the sleeve 63.

[0029] It should be noted that when measuring the angle of some steel structures at higher positions, the fixed rod 3 can be driven by the electric push rod 72 to slide in the fixed cylinder 71, so as to adjust the extended length of the fixed rod 3. Then, the two angle measuring rods 2 on the protractor 1 can be placed at the positions of the steel structure where the angle needs to be measured. According to the extended length of the fixed rod 3, the sleeve 63 can slide on the telescopic rod 62 to adjust its overall length. Subsequently, the position of the sleeve 63 on the telescopic rod 62 can be fixed by the bolt 64. The staff can apply a thrust to the sleeve 63 to push the adjusting cylinder 41 to slide on the fixed rod 3. The connecting rods 42 hinged on both sides of the adjusting cylinder 41 will respectively push the two sleeve blocks 43 to slide on the two angle measuring rods 2. Under the action of the thrust, the two angle measuring rods 2 rotate on the protractor 1 and open the corresponding angle. The angle of the steel structure is measured by the two angle measuring rods 2, and the reading can be taken through the protractor 1. During the process of the adjusting cylinder 41 sliding on the fixed rod 3, under the elastic action of the spring 53, the pressure rod 51 can apply a certain pressure to the fixed rod 3. When the adjusting cylinder 41 stops moving, under the elastic action of the spring 53, the adjusting cylinder 41 can be limited to the corresponding position on the fixed rod 3. When the angle measuring rod 2 contacts the steel structure, under the pressing action of the pressure rod 51, the rotation of the angle measuring rod 2 can be prevented, so as to maintain the stability of the angle measuring rod 2. This structure can realize the measurement of steel structures at higher positions and can effectively prevent the angle measuring rod 2 from rotating during the measurement of the steel structure, so as to maintain the measurement accuracy.
